A Comprehensive Guide For The Cooker Hood In 2024

Cooker Hood

A range hood, also known as a range hood, is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove and can quickly remove the waste from the stove and the oil smoke that is harmful to the human body generated during cooking and discharge it outdoors. At the same time, it condenses and collects the oil smoke to reduce pollution, purify the air, and has anti-toxic and explosion-proof safety protection functions.

The range hood needs to be cleaned regularly. Simple cleaning cannot remove the oil stains. Professional cleaning agents must be used to clean the range hood.

Background

In the early days, exhaust fans were used to exhaust smoke from home kitchens. Although exhaust fans can remove most of the kitchen smoke, they are unable to solve the pollution of the entire kitchen caused by cooking smoke. Cooking smoke contains many substances that are harmful to the human body. If people work in a room full of smoke for a long time, many diseases will occur. [1-5]
The WHO research report shows that among the 4.3 million people who died from kitchen air pollution in 2012, 34% suffered from stroke, 22% from chronic obstructive pulmonary disease and 26% from ischemic heart disease, and about 6% died from lung cancer.

In a research project on disease risk assessment published in the famous British medical journal The Lancet, kitchen air pollution (smoke) has been listed as the biggest health hazard after hypertension, smoking and alcoholism. The number of people who die each year from continuous inhalation of smoke from kitchen fires is more than the total number of deaths from malaria, tuberculosis and AIDS.

A study on Chinese farmers published in the Journal of the National Cancer Institute in the United States also confirmed the impact of kitchen air pollution on human health. Chinese and American scientists who participated in the study surveyed more than 20,000 farmers in Yunnan Province and found that farmers who had no ventilation in their stoves were about twice as likely to develop lung cancer as those who had chimneys or ventilation equipment added to their homes. The researchers said that using stoves without ventilation is about the same as smoking in causing lung cancer.
 

Main classification

According to the appearance, range hoods can be divided into three types: Chinese range hoods, European range hoods, side suction range hoods, and multimedia intelligent range hoods. [1] They can also be divided into upper exhaust, side exhaust, and lower exhaust.

Chinese range hoods

Mainly divided into old-fashioned shallow and deep suction range hoods, especially shallow suction range hoods, which are the main targets for elimination. They are ordinary exhaust fans that directly exhaust oil fumes to the outside. The biggest problem with deep suction range hoods is that they take up space, make a lot of noise, are easy to hit your head, drip oil, and the oil fumes cannot be completely extracted. They have a short service life, are inconvenient to clean, and cause great pollution to the environment.
 

European range hoods

Use multiple layers of oil mesh to filter {5-7 layers} and increase the motor power to achieve the best effect. The general power is above 200 watts. Features: beautiful appearance, relatively expensive, suitable for high-end user groups. Most of them are flat mesh filter oil mesh and hanging installation structure.

Side suction type

The advantages are that it is not easy to hit your head, the appearance is fashionable, the suction port is close to the oil fume generation point, the suction and exhaust effect is good, and young people like it. If the design is not good, oil is easy to accumulate at the bottom, and the raised part is easy to affect the operation.

L-type range hood

The L-type range hood is improved to solve the problem of side suction type. The original side protruding suction is changed to two upper and lower suction ports. The main suction port concentrates the suction force in the lower area close to the oil fume generation point, and concentrates almost all the power to suck it away before the oil fume spreads. A very small part of the oil fume that is not sucked in rises along the smoke guide plate to the top and is sucked away by the auxiliary suction port.

Intelligent range hood

The perfect combination of modern industrial automatic control technology, Internet technology and multimedia technology provides a model for modern smart kitchens and leads modern kitchens into a dynamic era of entertainment and enjoyment. However, there are still certain technical bottlenecks before it can be popularized.

According to the type of fan, range hoods can be divided into axial flow and centrifugal types. Axial flow fans are generally equipped with shallow hoods, with large air volume and low air pressure; centrifugal fans have high air pressure. The range hoods sold on the market are mainly centrifugal, so there is not much room for choice in the model. Generally, they are external exhaust type with centrifugal fans.

According to the structural form, range hoods are mainly deep and thin, and there are also semi-deep, European and pull-out models. There are three types of range hoods on the market: thin, deep and cabinet.
Deep range hoods have a high exhaust rate and can match modern kitchen furniture of different styles. The deep outer cover can absorb cooking fumes in a larger range. Its deep body is convenient for installing powerful motors, which greatly improves the exhaust rate of the range hood.

Thin range hoods are light, small and easy to hang, but their thin design and low motor power prevent a considerable part of cooking fumes from being included in the extraction range, and have the opportunity to escape indoors. Its exhaust rate is significantly lower than the other two types of models.

The cabinet-type range hood consists of a fume hood and a special range hood. The range hood is conical. When the fan is turned on, a negative pressure area is formed in the cabinet, and external air is replenished inside. The opening in front of the fume hood forms an air inlet, so that oil smoke and other exhaust gases cannot escape, ensuring the extraction rate of oil smoke and nitrogen oxides.

According to the number of motors, range hoods are divided into single-motor and dual-motor types.
According to the different control methods, range hoods can be divided into mechanical switch control type and electronic switch control type. [2-3]

Equipment structure

The range hood mainly consists of a housing, air duct, fan, check valve, oil collection and exhaust device, lighting device, power switch and power cord. [5]

Case

It consists of two parts: the housing and the panel. It is made of cold-rolled thin steel plate with plastic spraying treatment. It is not only smooth in appearance, beautiful and rust-proof, but also durable and easy to clean.

Motor

The motor is the core part of the range hood. It adopts a fully enclosed single-phase capacitor-operated asynchronous motor; the iron shell is fully enclosed, the motor bearing is a double-row ball bearing, the insulation level is E-pole insulation, and the capacity of the starting capacitor is about 4 microfarads.

Wind wheel

It adopts a centrifugal wind wheel. Its diameter is 220mm/240mm. It is stamped from silicon alloy aluminum sheet, durable and non-deformable, and has good dynamic balancing performance.

Wind duct

It is the passage for smoke. It is made of cold-rolled thin steel plate with plastic spraying treatment. The rationality of the wind duct structure determines the exhaust volume and noise of the entire range hood.

Check valve

It is made of plastic and its function is to prevent smoke backflow.

Smoke exhaust device

It consists of an oil collection box, a smoke exhaust pipe, an oil collection cup and an oil guide ring.

Lighting device

Ordinary Chinese machines use 15~40W incandescent screw bulbs: European machines and near-inhalation machines use cold light source lamps, and there is a detachable transparent organic glass sheet on the outside to seal the lamp to prevent the oil smoke from contaminating and corroding the lamp during cooking, ensuring the safety of the appliance.

Power switch

A touch switch or mechanical switch is used to control the working state.

Power saving strategy

1. Turn on strong wind when starting up. Many people think that using a low wind speed on a range hood can save electricity. In fact, the range hood consumes the most power when starting up. When the low wind speed is turned on, it will consume more power when starting up due to the slow running speed, while the high wind speed is also energy-saving when starting up due to the fast running speed. Therefore, it is best to turn on the high wind speed first and then turn it down when starting up.

2. Do not disassemble and clean frequently. Improper cleaning methods may also increase power consumption during use. Frequent disassembly and cleaning of range hoods will cause parts to deform, thereby increasing resistance and increasing power consumption. In fact, oil smoke generally does not enter the motor, so it is recommended to clean the surface.

3. Do not wipe when cleaning. Some people are used to wiping the oil stains on the fan blades when cleaning the range hood, but this may cause the fan blades to deform, increase resistance and waste electricity. Therefore, when cleaning, you can spray detergent on the fan blades and let the fan blades rotate and dry. 4. Use the small light on the range hood. Some people are used to turning on the lights in the kitchen when cooking, but using the low-power lighting equipment on the range hood is enough. This not only makes full use of the function of the range hood, but also saves electricity. 5. Do not use it for deodorization. Some people use the range hood as a ventilation device and often use the range hood to dissipate odors. In fact, the ventilation range of the range hood is small and the ventilation effect is slow, so it will consume more electricity.

Working principle

The range hood is installed on the top of the stove. When the power supply of the range hood is turned on, the motor is driven to make the fan wheel rotate at high speed, so that a negative pressure area is formed in a certain space above the stove, and the indoor fume gas is sucked into the range hood. The fume gas is filtered through the oil net and separated for the first time, and then enters the air duct of the range hood. The second fume separation is carried out by the rotation of the impeller. The fume in the wind cabinet is subjected to the centrifugal force, and the oil mist condenses into oil droplets, which are collected in the oil cup through the oil path. The purified fume is finally discharged along a fixed passage. [1-5]

How to choose

Criteria for choosing

Exhaust rate

First, choose a range hood with a high exhaust rate. Kitchen fumes can cause damage to the human respiratory system. Data show that respiratory diseases account for the largest number of deaths in China. Coal smoke-type fluorine poisoning and arsenic poisoning have become endemic diseases among residents in some areas. The purpose of installing a range hood is to remove fumes during cooking and reduce indoor pollution. Therefore, when choosing a model, you should first choose one with a high exhaust efficiency.

Negative pressure

Second, choose a range hood with a high negative pressure. The greater the negative pressure of the range hood, the stronger its exhaust capacity. As you mentioned, the range hoods on the market are divided into flat-type, semi-deep, deep and cabinet types. The "negative pressure area" they generate is different due to their different structures. Most deep range hoods have a negative pressure area of ​​about 0.14 cubic meters and a smoke exhaust efficiency of about 60%. The negative pressure area of ​​cabinet range hoods is about 0.32 cubic meters and a smoke exhaust efficiency of more than 95%. However, since the cabinet-type range hood is enclosed on three sides, it is not as luxurious as the hanging-type range hood in appearance.

Purchase Misconceptions

According to research, among non-smoking women who are prone to lung cancer, more than 60% of them are exposed to kitchen fumes for a long time. In a kitchen environment with poor exhaust effect, the harm to health is equivalent to smoking two packs of cigarettes a day, which causes 1.6 million deaths worldwide each year. Experts point out that in addition to correctly controlling the oil temperature and cooking time, it is also necessary to choose the right range hood. [1-3]
Due to the close-range suction and open design of side-suction range hoods, side-suction range hoods have gradually occupied the market and become a major mainstream in the range hood market. However, in the face of a wide variety of side-suction range hoods, consumers should keep their eyes open when choosing side-suction range hoods and avoid the following six misconceptions.

Misconception 1: "Circular air inlet can provide 360° air intake" misconception. Many side-suction range hoods on the market have a circular inlet in the middle, claiming to provide 360° air intake. But in fact, the oil smoke produced by the two burners of the stove is distributed on both sides, and the smoke entering from the center can only ensure that the smoke closest to the center area enters in all directions, and the smoke farther away can easily escape, so this 360° air inlet is only a 360° open design, not to achieve full smoke entry. So in order to let the smoke from the two burners be sucked in at the same time, a wide air inlet must be guaranteed.

Misconception 2: "The larger the air volume, the better the smoking effect" Misconception. The quality of smoking effect cannot be judged only by air volume. Too much air volume not only cannot suck oil smoke, but also disrupts the flow direction of oil smoke gas. The "Eleventh Five-Year Plan" research shows that the most suitable air volume for public flues is 15m3/min, not the larger the better. And theoretically speaking, the air volume and noise of the fan are a natural contradiction. The larger the air volume, the more unbearable the noise.

Misconception 3: "It is cleaner with an oil net" Misconception. Side suction smokes at a close distance, so naturally the smoke is exposed to oil smoke earlier. When the gaseous oil contacts the oil net, it begins to condense into liquid when it is cold. When the oil droplets condense to a certain degree, the smoke can no longer pass through. Therefore, in order to change the trouble of having an oil net, technical experts have developed an oil net-free design with "triple oil smoke separation technology". Through multi-layer technology, oil smoke is filtered, becoming a modern side suction machine. It is a technological innovation and solves the problem of cleaning the oil net for customers. [1-3]

Misconception 4: "Side suction machines that do not require disassembly and washing are really free of disassembly and washing." The real oil smoke separation relies on the centrifugal force generated by the high-speed rotation of the impeller to separate the oil smoke. The side suction machines on the market that claim to be free of disassembly and washing claim to be able to completely filter the oil smoke through the filter, but the filter is only for the first oil smoke separation. It is obviously impossible to expand the function of a filter and turn it into a net that can filter out all the oil smoke from thousands of households. Only with better fan anti-oil coating and good daily maintenance can the range hood be guaranteed to operate efficiently for a long time.

Myth 5: The panel material is irrelevant
Regarding the panel material, the salesperson may "deliberately forget" to mention it, or directly mention a certain alloy name to fool consumers. In fact, it is very simple to check the material. The best domestic material is generally imported M-Cr fine steel, which looks fine and textured. This material is resistant to oxidation and corrosion and will become brighter and brighter as it is polished. To distinguish the difference between this material and general alloy materials, you only need to use a magnet to test it directly. If it can be attracted, it must be a general inferior alloy or iron, and if it cannot be attracted, it is made of fine steel. There is also a panel protected by Teflon coating, which has the advantages of non-stick oil, easy cleaning and corrosion resistance. It is another excellent panel material besides stainless steel.

Myth 6: The inner cavity design is not important
The importance of the inner cavity design of the range hood cannot be ignored. On the one hand, it should be as seamless and easy to clean as possible, and at the same time, it should be able to protect the circuit so that various circuits can work normally under the strong corrosive conditions of oil smoke and not be corroded. The seamless design of the inner cavity is not only seamless inside the cavity, but also the small surface parallel to the stove top should be seamless. At the same time, the junction between the oil net and the inner cavity should also be "invisible and seamless", such as setting up an oil-proof wall, so that there is really no dead corner for cleaning. [1-3]

Identification standards

Since the 21st century, there have been more than 400 manufacturers of range hoods in China, some of which are small workshops with more than a dozen people, and some products have not been certified by national authorities. Therefore, when choosing, consumers should choose products with various technical indicators that meet national standards. Be sure to choose products with guaranteed product quality.

The following four standards should be used to evaluate the quality of range hoods:
1. Whether the kitchen fumes can be completely extracted
2. Whether the oil and smoke can be separated to effectively protect the fan
3. Whether it is easy and convenient to clean
4. Whether it saves electricity and maintains super strong efficacy for a long time
Using the above four standards to examine traditional range hoods, you will naturally know why the range hood industry has not been satisfactory for so many years. [1-3]

Common models

Traditional type

Traditional range hoods are all ceiling-mounted designs, and the installation height is generally around 700mm. The fan power of its mainstream models is mostly between 200~250W, so its effective suction radius is roughly around 400mm, so the pot surface is completely outside its fan suction range, so that the oil smoke will naturally spread everywhere once it is generated from the pot surface. In order to exhaust cleanly, from the principle of air power mechanics, it can only lower the height so that its effective suction radius covers the pot surface, and naturally it can also achieve 99% of the suction effect, but this obviously cannot cook. After careful analysis, it is not difficult to find that this ceiling-mounted design is the fundamental reason why traditional range hoods cannot exhaust cleanly.

Traditional range hoods use oil filter nets to filter oil smoke. There are one, two or more layers, and the filter holes are square, diamond, round, etc. The purpose is to hope to block the oil smoke through the filter. However, from the use of so many years, the effect of this solution is very poor. Even if the filter is as small as 0.01 square centimeters, 37% of the oil smoke cannot be blocked. The filter holes of most range hoods on the market are about 0.04 square centimeters, so they are almost directly discharged. The result is that the inner wall of the range hood is polluted, causing a large amount of uneven oil accumulation on the fan impeller, and the fan rotation loses dynamic balance, so the suction effect is naturally getting worse and worse, and its mechanical noise is getting louder and louder. In short, the lack of effective purification function is the rapid decline of the effectiveness of traditional range hoods. Third: Due to the defects of its ceiling design and the lack of effective purification means, in order to ensure the suction effect in the short term, its power is generally high (mainstream models are between 200W and 250W), which is obviously very power-consuming.
Due to the lack of effective purification means, a large amount of oil accumulates in the fan and the inner cavity of the machine, which is very difficult to clean. Generally, it requires professionals to complete it. Sometimes the effect is worse after cleaning, which is time-consuming and laborious.

Exhaust-free type

How to use: Insert the power plug into a three-core power socket with a grounding device.
(1) In the off state, press the "strong" or "weak" button to start the range hood and run it in the strong wind or weak wind state. The "strong" and "weak" buttons have an interlocking function.
(2) The "light" button is used to control the lighting lamp separately. Press it once to turn on the light, and press it again to turn off the light.
(3) In the on state, press the "off" button to stop the range hood in the running state.

Precautions:

(1) The gas discharged by the exhaust-free range hood should not be discharged into the hot flue used to exhaust the smoke from burning gas or other fuels to prevent fire.
(2) When the exhaust-free range hood is used when the stove consumes gas or other fuels, the room must be well ventilated.
(3) It is forbidden to directly bake the range hood with the stove fire.
(4) A reliably grounded power socket must be used.
(5) If the power cord is damaged, it must be replaced with a special cord or a special component purchased from its manufacturer or maintenance department.
(6) If the range hood is not cleaned according to the instructions, there is a risk of fire.
(7) When replacing a light bulb, please unplug the power first. The power of each light bulb should not exceed 20W.
(8) When cleaning, please wear rubber gloves to prevent metal parts from injuring people. Removed parts should be handled with care to avoid deformation.
(9) When cleaning the impeller, be especially careful not to collide with it, deform it, or move the weight of the blade, otherwise it will cause the whole machine to vibrate and increase the noise.
(10) Please unplug the power cord when not in use for a long time. [1-4]

Notes

Many users only turn off the range hood after turning it on for a few minutes when cooking, which does not make it work. The correct way to use it is to turn it on as soon as cooking starts and not turn it off until 5 to 6 minutes after the entire cooking process is completed. This is because natural gas or liquefied petroleum gas, when the range hood is not used, will exceed the standard by 5 times in just a few minutes of burning nitrogen compounds, and carbon monoxide gas can exceed the standard by more than 65 times. Therefore, during the cooking process, the range hood should be operated throughout the process and cannot be turned on and off. As for the reason why it still needs to work for a few minutes after cooking is finished, it is to exhaust the harmful gases remaining in the kitchen to the greatest extent possible, so that they will not remain in the kitchen to prevent harm to human health. [1-4]

Installation method

MUM KiTCH provide Appliances Installation Services 
1. Installation environment of range hood:
Avoid too many doors and windows around the range hood, because when there are too many doors and windows, the air convection will be too large, so that the oil smoke will spread a lot before it rises to the effective suction range of 250mm, and the effect of oil smoke extraction will be affected.

2. The range hood should be installed directly above the oil smoke exhaust gas, and the height should be 650~700mm.

3. Installation requirements of the exhaust pipe of the range hood:

(1) The distance from the exhaust outlet to the machine body should not be too long, and the turning radius should be as large as possible and the number of turns should be small, otherwise the exhaust effect will be affected.

(2) The exhaust pipe extends to the outdoors or leads to the shared cold air flue. The interface should be tight and the exhaust gas does not need to be discharged into the hot flue.

4. Keep the range hood body level: After the body is installed, observe its levelness.

5. The range hood should be installed directly above the center point of the gas stove.

6. Try not to install the range hood near doors and windows where air convection is strong, so as not to affect the effect of extracting oil fumes.

7. The air outlet pipe should not be too long, preferably not more than 2 meters, and try to reduce bending and avoid multiple 90-degree bends, otherwise it will affect the effect of extracting oil fumes.

Some electrical appliances such as range hoods and TVs will indeed cause safety hazards other than leakage if they are not installed in a standardized manner. Standardized installation is the most important thing. For safety reasons, hurry up and check each room one by one.

The range hood must be fixed directly to the wall. The formal installation method of the range hood is to use expansion bolts to fix the range hood horizontally on the concrete or brick wall. It cannot be directly fixed on the non-load-bearing wall, let alone on the cabinet. The range hood that has been fixed on the cabinet must be removed and reinstalled. In addition, when installing the expansion tube, the pipe hole and the drilling hole must be closely matched. It is strictly forbidden to drill too large a hole to loosen the expansion tube and cause the machine to fall; when the range hood needs to be installed separately, the stop plate in the random accessories must be installed in place to prevent the machine from falling off.

A plastic bag is taped underneath to hold the wall-breaking particles to prevent them from falling onto the countertop.

1. Drill 3-10 holes in the wall with a depth of 50-55mm, bury 10 plastic expansion tubes, and then fasten the hook (accessory) with wood screws.
2. Insert the exhaust hose into the check valve assembly and fasten it with self-tapping screws.
3. After lifting the whole machine, align the two rectangular holes on the back wall with the hooks and hang them, then lead the exhaust hose to the outside. Note that the outlet of the exhaust hose should be lower than the indoor level.
4. Install an M5x25 screw in the screw hole in the middle of the hanging plate and tighten it to prevent the range hood from slipping. The installation is now complete. [1-2] [5]

Cleaning method

Disassembly and cleaning

MUM KiTCH provide Appliances Cleaning Services

Body

Before using the new range hood, sprinkle a thin layer of soap powder in the two oil storage boxes, and then add about one-third of water. In this way, the recovered oil will float on the water surface instead of condensing on the box wall. When the waste oil is almost full, pour it out and do the same.
Before using the range hood, you can use a slightly damp rag dipped in dishwashing detergent (do not add water) to wipe the body, and wipe the fan blades as much as possible. After it dries naturally, the "detergent coating" to prevent oil smoke from sticking is ready. After a period of time, if the body feels sticky, it is time to clean the body. Since the "protective coating" has been applied between the oil and the body, the oil will be washed off first by directly washing the body with 80℃ hot water. After the cleaning work is completed, apply detergent on the body again. Apply it a little thicker and control the humidity to "not drip". Then cover the switch with plastic wrap. [1-3]

Oil storage box

The waste oil in the oil storage box of the range hood is filtered out to the top layer, which is the "best degreasing agent" for cleaning the ventilation fan, stove and range hood stains. The specific method is to dip the waste oil into a rag or a torn towel and apply it to the oily area. After soaking for about half a minute, wipe it off with a cloth, and then wipe it with a clean scouring pad. At this time, the body of the range hood is so bright that it can be "reflected in a mirror".
In addition to the "water storage cleaning method" mentioned above, stick a layer of plastic wrap inside the box or put a small plastic bag filled with tangerines on the inner wall of the oil storage box to ensure that the plastic film or plastic bag completely covers the inner surface of the box and "holds" the absorbed waste oil. Then, after a period of time, remove it and replace it, and the oil storage box will basically be clean.

Oil screen

The oil screen that protects the fan blades can be slowly removed with a screwdriver, sprayed with "Oil Fume Cleaner" and placed in a plastic bag. Let it stand for 15 minutes and then take it out. Pour 80℃ hot water into a basin and clean it carefully with a rag. If the oil stains on the oil net are very thick, you can also use a thin bamboo piece to gently scrape off some of the oil stains before cleaning.

Fan blades

Is it necessary to use "oil fume cleaner" to clean the fan blades? Not necessarily. Although the oil fume cleaner has a strong saponification and emulsification ability on the oil stains on the machine body and fan blades, cover the countertop under the range hood with newspapers, spray the oil fume cleaner on the machine body and fan blades, turn on the range hood after a few minutes, use the centrifugal force of the fan to extract the oil fume cleaner and the dissolved dirty oil, and then wipe it again with a wet paper towel. The cleaning of the machine body and fan blades is done. However, the oil fume cleaner is a chemical product after all, which has a certain irritating effect on the skin and respiratory mucosa, so it is better to use it less. Here are four "oil fume cleaner-free" fan degreasing methods, you can try:

1. Detergent and vinegar soaking method. Carefully remove the fan blades and soak them in a basin of hot water mixed with 2 ml of detergent and 50 ml of vinegar. After soaking for about 15 minutes, wipe them with a clean rag. The body of the range hood is also cleaned with this solution. Be careful to keep the solution humidity at around 60°C for good decontamination power. This self-mixed cleaning solution has been proven to be non-irritating to the skin of the hands and the mucous membranes inside the eyes, non-corrosive to the range hood, and the surface remains glossy after cleaning.

2. Pressure cooker steam flushing method. Put half a pot of cold water in the pressure cooker and boil it. When steam is continuously discharged, remove the pressure limiting valve, turn on the range hood and aim the steam water column at the rotating fan blades. As the high-temperature steam continuously flushes the fan blades, the oily water will flow into the waste oil box along the oil drain tank.

3. After the washed fan blades are dried, apply a layer of office glue. After a few months of use, tear off the oil stains on the fan blades in pieces. The oil stains are all on the glue layer, which is convenient and clean.
4. First, lay newspapers on the stove, turn on the switch of the range hood to "preheat" the fan blades for two minutes, spray detergent on the fan of the range hood, turn off the range hood, let it stand for three minutes, then spray 60℃ hot water into the fan of the range hood, turn on the switch again, and let the dissolved oil drip into the oil storage box. [1-3]
 

Other methods

Most people are used to disassembling the range hood for cleaning, which is not only time-consuming but also easy to damage the parts. Now we introduce a cleaning method that does not require disassembling the machine and is very time-saving and labor-saving.

1. Take a plastic bottle (any beverage bottle that can be flattened by hand will do), use a sewing needle to poke more than 10 small holes on the cover, then fill it with an appropriate amount of detergent, and then fill it with warm water and shake it evenly.
2. Start the range hood, use the plastic bottle filled with detergent to spray the cleaning liquid on the part to be cleaned, and you can see that the oil and dirty water flow into the oil storage bucket together, and pour it out as it fills.
3. After the cleaning liquid in the bottle is used up, continue to prepare and repeat the cleaning. Until the dirty water flowing out becomes clear. Depending on the degree of dirt accumulation, it can be rinsed clean after three cleanings.
4. If there is a mesh cover on the fan blade, it is advisable to remove the mesh cover first to enhance the cleaning effect.
5. Use a rag to wipe the area around the air inlet, the surface of the casing and the lampshade.

Cleaning tips

How to prevent oil stains on kitchen gas pipes:

Building users who use pipeline gas will encounter this situation: the oil stains adhering to the gas pipes are thick and difficult to remove. Here is a preventive method: First, thoroughly clean the oil stains that have penetrated into the gas pipes, and then use paper strips (about 5 cm wide) cut from waste calendars to wrap them along the gas pipes. This is not only beautiful, but also very convenient to replace when the paper strips are dirty.
A trick to remove oil from kitchen range hoods:

After using the range hood, the oil pan should be cleaned. You can put the plastic bag used to wrap oranges into the oil box and stick it close to the box wall. When the oil in the box is full, remove the bag full of oil and replace it with a new bag. This can not only solve the trouble of not washing the oil clean, but also use the waste plastic bags and save time.

The waste oil in the oil box of the range hood can be used:

Many family kitchens use range hoods, and their oil boxes are full of waste oil in a few days. It is the best "degreasing agent" to use it to remove stains on kitchen window frames, ventilation fans and range hoods. Specific method: Dip a rag or a torn towel in the waste oil and apply it to the oily area, then wipe the oil with a cloth, and then wipe it with a clean cloth. Objects with thick oil stains can be soaked in waste oil for a few seconds, and then wiped off with a cloth after the oil stains soften (especially thick ones need to be scraped with a thin bamboo board.)

The oil in the oil box of the range hood can be used. Doors and windows are connected with iron hinges, and they are often opened and closed. Wear is very severe. You can use a small wooden stick to put waste oil on the hinge shaft, which not only extends the life of the hinge, but also reduces noise.

There are some tips for cleaning the oil collection box of the range hood:

When the oil collection box of the range hood is full of oil, the oil stains adhering to the bottom and walls of the box are difficult to remove. If you sprinkle a thin layer of detergent on the bottom of the box and add a little water after each cleaning, the oil is lighter than water, and the accumulated oil will float on the water. When cleaning, pour out the oil in the box, and there will be no oil stains adhering to the bottom of the box. It is easy to clean with detergent.
How to clean the tiles around the gas stove:

The white tiles around the gas stove are easily contaminated by oil splashes and smoke, and are not easy to wipe clean. According to a friend, you can use the unused calendar colored plastic film, apply goldfish detergent around the edges and stick it on the tiles. This can save wiping time and you can change it every few months according to your favorite pattern.
