How to solve the problem that the range hood does not smoke? What is the reason why the range hood d

The range hood can be divided into two types: one is that the motor can rotate, and the common one is that the air inlet or outlet is not passable, and the fan blades are damaged or fall off or are too dirty; The second is that the motor cannot be rotated, which may be a switch failure, a circuit board failure, or a failure of the motor or its related circuits. It is recommended to find a professional to come to inspect and repair.

Extended information: The cleaning method of range hood first needs to prepare cleaning liquid, add a certain amount of vinegar and wash in water. Refine, then stir well.

Remove the box of the range hood with grease, wipe the remaining grease inside with a paper towel, and then place it in the washing solvent to clean it again. If there is a solid residue in the box that is difficult to clean, it can be cleaned with a steel wool ball. Finally, clean the box with clean water.

The top of the range hood is also a difficult place to clean, you can spray the solution to the top grease and scale, and then use steel wool balls and sponge cloth to scrub the surface of the range hood clean. The smooth surface of the range hood is easy to clean, just wipe it back and forth with a sponge cloth dipped in cleaning liquid. Tips:

If the range hood is not cleaned for a long time, there will be great harm, the oil stain in the snail shell and the oil stain of the wind wheel will directly affect the smoke exhaust efficiency, and the long-term smoke exhaust will not be smooth will affect the human body.

The range hood produces air but does not smoke, indicating that the air output is not enough and the suction force is too small, so the smoke cannot be extracted; The solution is to consider whether it is time to clean it first, generally speaking, the smokeless machine should be cleaned at least once a year; If the air outlet is still small after cleaning, it means that there is a problem with the smoke machine, and the common fault is that the parallel capacitor of the motor is broken, and the voltage cannot go up, so the speed is too slow; The solution is to find a professional to carry out repairs; If it is said that the professional cannot repair it, or there is no maintenance value if there is a problem with the motor, the range hood can only be replaced.

There are two ideas to solve, 1Please ask someone or repair it yourself, and call ** to after-sales service during the warranty period, 2Buy a new one and install a new one.

It may be that the air duct is blocked, or it may be that the motor is broken.

The main reasons are: 1. The suction channel of the range hood is blocked by oil pollution. 2. The smoke exhaust pipe is blocked by foreign objects.

3. The motor is damaged, and the range hood is not pumping. 4. The exhaust pipe is too long, resulting in too much resistance increase. 5. The installation point of the range hood is too high from the stove.

6. Caused by damage to the sealing strip. Suggested solutions: 1. If the installation position of the range hood is too high, it is recommended to reduce the installation position appropriately.

2. If the exhaust pipe is too long, or the direction of the air outlet is not suitable, you can appropriately shorten the exhaust pipe, or re-select the direction of the air outlet. 3. If it is an air leak caused by the sealing strip of the range hood, the sealing strip needs to be replaced. 4. If the voltage is too low, a voltage regulator can be configured if necessary.

5. After checking the exhaust pipe, if it is found that the partition in the middle of the exhaust pipe is not straightened, not opened, or the exhaust pipe of the range hood is blocked due to other reasons, the corresponding dredging can be carried out. 6. If the range hood does not turn when the motor is not turned on and accompanied by a buzzing sound, the motor is generally damaged and the capacitance capacity is reduced, resulting in the motor not being able to start normally, so it is considered to replace it with a new capacitor of the same type.

The main reasons are: 1. The flue may be blocked, and the check valve.

It cannot be opened, resulting in no ventilation. 2. The motor of the range hood does not work, resulting in the fan not rotating, which cannot form a low pressure area, and there is no way to realize the flow of wind. 3. The middle of the air duct is not strict, and there is a phenomenon of air leakage, resulting in insufficient air pressure.

4. The airtightness of the use environment, etc. Treatment method: 1. Clean the range hood and flue regularly, the range hood will inevitably appear oil stains after a long time, sometimes only see the outside of the range hood is very clean but the inside is not visible, so it is necessary to clean the flue regularly, check valve can choose a lighter material, easier to open the exhaust effect is better.

2. Check whether the motor is working normally, if it works, see if there are a lot of stains that cause the fan speed of the range hood to not reach, so that the speed of the fan is relatively low, and the ability to extract air decreases. 3. The main principle of exhaust is to use wind pressure.

Check whether there is a leak or gap in the air duct, and repair it in time, so that the air pressure can be stable and the range hood can work normally. 4. The airtightness of the main kitchen, do not leave the windows and doors open, so that the convection is too strong, and most of the oil smoke will drift away with this convection.

There are many reasons why the range hood does not smoke oil, what should we do when we encounter such a situation, only by checking out the reason, it will be easy to repair, first of all, let's see what reasons will cause the range hood not to smoke.

Range hood does not smoke Reason:

1. The partition in the middle of the exhaust pipe is not directly placed or opened (there is such a door in the exhaust pipe of the old-fashioned range hood), or the exhaust pipe is artificially blocked.

2. The wind wheel is reversed or damaged.

3. The smoke exhaust pipe is blocked.

4. The capacitor is damaged (two-phase electricity needs capacitors to rotate forward, and three-phase electricity does not need capacitors), resulting in the reversal of the motor of the range hood, which may not see oil droplets in the oil drop box.

5. The motor is damaged, the power becomes smaller, or the exhaust pipe is too long, and the resistance increases too much.

Solution: 1. Listen to the sound of the wind, turn the air volume of the range hood to the highest, and then open it to the maximum, and then listen carefully to the sound, if the wind sound has only one "whirring" sound, it means normal, if there is a different sound, it means that the air outlet is blocked.

2. Look at the wind wheel. This situation is rare, generally does not appear, is to observe whether the wind wheel of the range hood is rotating in the counterclockwise direction, if it is the opposite, there is no air volume. If the rotor itself is damaged, the bearing may be damaged, and the rotor needs to be replaced.

3. Test the suction. The same is to turn on the air volume of the range hood to the maximum, and then use a newspaper to stick to the air outlet, see if the newspaper can be sucked, and then pull out the smoke exhaust pipe of the range hood to see if the wind is the same as the last time, if the difference is very large, then it can be concluded that the smoke exhaust pipe is blocked. If the air volume is about the same twice, then it is a quality problem of the range hood.

4. The motor is damaged, so the smoker should stop working, there is no buzzing sound, and it is easy to judge.

5. Light the lighter or candle, start the motor, check whether it is suction or blowing, blowing proves that the motor is reversed, and the suction proves that the motor power is too small, the fan blade is deformed, and the exhaust pipe is too long.

1. There is generally a partition in the middle of the exhaust pipe of the range hood, if this partition is not directly placed or not opened, then the range hood will not smoke. If the crack of the exhaust pipe of Beiyuanming is artificially blocked, it will also cause the range hood to fail to smoke. At this time, it is enough to put the partition straight, or open the partition, or clean the exhaust duct.

2. If the wheel of the range hood is reversed or damaged, it will also cause the range hood to not smoke, and a new one needs to be replaced.

3. If the exhaust pipe of the range hood is blocked, then it will cause the range hood to not smoke, and then you need to clean the exhaust pipe.

4. If the capacitance of the range hood has been damaged, it will cause the motor of the range hood to reverse, resulting in the range hood not smoking, and a new capacitor needs to be replaced.

5. If the motor of the range hood is damaged, the power will become smaller, resulting in poor smoking effect of the range hood, or even no smoking, then it is necessary to replace a new motor.

6. If the exhaust pipe is too long, the resistance will increase and become very large, which will also lead to poor smoking effect of the oil extraction imitation smoke machine, or even no smoking, then you need to adjust the length of the exhaust pipe.

Note. 1. Use a special power socket. The special socket is firmly grounded, the power wire is connected normally, no extension cord is used, and too many electrical appliances are not used, otherwise it is easy to have wire heating, short circuit, electric shock, etc.

2. Cut off the power supply during cleaning. It is dangerous to clean the range hood when it is powered on, and it is easy to get an electric shock accident due to misoperation.

3. Do not touch electrical components with wet hands. In the kitchen, it is often necessary to clean the dishes, and when your hands are wet, you cannot directly touch the power plug and operate the switch, otherwise it is easy to get an electric shock.

4. It is strictly forbidden for electrical parts to get wet. Clean the range hood, be careful not to drip water onto the motor, switch, and connector, otherwise there may be a risk of electric shock.

5. Non-professional maintenance personnel are absolutely forbidden to change the internal circuit without permission, otherwise abnormal actions may occur and cause human injury, and electric shock and fire may occur if the repair is not done properly.

1. The wind wheel is reversed or damaged, maintenance method: the wind wheel needs to be removed and reinstalled when reversed, and it is recommended to replace the wind wheel if it is damaged. 2. The smoke exhaust pipe is blocked, maintenance method: clean up the debris in the smoke exhaust pipe. 3. The capacitor is damaged, resulting in the reversal of the motor of the range hood.

Can't smoke cigarettes, maintenance method: replace the capacitor. 4. The motor is damaged, the power becomes smaller, or the exhaust pipe is too long, and the resistance mountain force increases too much resulting in non-smoking, maintenance method: It is recommended to replace the motor. Expansion: Range hoods.

Routine maintenance. 1. Crush the leftover soap that is often used in the home to slip and dry, add water and stir into a paste, and then apply it to the place where the range hood has more oil stains, after a period of time, scrub with a clean rag, and then apply a layer of soap paste, Xinsheng can prevent oil pollution and make the range hood bright as new. 2. The gap between the fan blades is small, and it is difficult to put your hands into it when cleaning, if you want to clean it, you need to remove the fan blades and scrub them slowly.

After scrubbing, you may wish to apply a layer of glue to the fan blades, and after a few months, remove the oil-stained glue sheet and reapply it, so that you can continue to use it again. 3. Although the cleaning of the oil storage box is not difficult, the anti-oil stain work must be done well, and it is recommended to paste a layer of plastic wrap in the box.

Cover the box completely and slightly beyond the surface of the box, let the fumes adsorb on the plastic wrap, and then smoke up after a while and replace it with a new one. 4. Every time you finish cooking, don't turn off the range hood immediately, let it continue to run for 1 minute, and pull out the residual oil smoke outdoors to achieve the purpose of fully eliminating oil smoke and reducing oil condensation.

If you are new and have just used it, check the installation height and smoke exhaust pipe. The installation height is too high, and the suction power is not strong; The smoke exhaust pipe is too long and bent more, which will also affect the smoking effect, so it is recommended that the length of the smoke exhaust pipe be controlled within meters, and the number of bends is 1 time; If it has been used for a long time, too much oil on the oil net will affect the oil absorption effect, it is recommended to clean the range hood. If it still doesn't work, it is recommended to contact the manufacturer for after-sales inspection and processing.

Quite simply, your range hood has been around for a while, is it a public flue? There is a return smoke check valve at the connection between the flue and the smoke pipe, and there is too much oil stain, resulting in the valve not being opened.

Otherwise, there is also a check valve at the connection between the range hood and the smoke pipe, which can be removed and replaced or cleaned.

If you have any questions, please ask.

The accessories of the range hood need to be assembled according to the original, so that the device can achieve the best effect and stable performance. Wrong installation will cause problems such as poor device effect, use failure and so on.

It's the piece of air that fell down, just open it and take it out, my machine is like this, and the range hood has been solved recently, and they asked me for 90 yuan. It's easy to repair, repair it yourself, and it's expensive to wipe the range hood.

If the smoking sound is uneven after the range hood is started, it is possible that the flue is blocked, and it is good to clean it up. If the range hood does not respond when the switch is pressed, it is possible that the switch circuit board of the range hood is loose or broken, and it is recommended to contact the brand after-sales service for on-site maintenance.

If the range hood is used for too long, or if it is not cleaned for a long time, it will also affect the smoking effect, you can clean the range hood, or change to a new range hood.

During the working process of the range hood, the impeller rotates at high speed in the vortex shell, and a negative pressure is formed in the vortex shell, and the oil smoke is sucked into the machine by the strong air flow in the rising process, and is cooled and separated by the impeller for a long time, and some oil stains will accumulate on the impeller, which increases the weight of the impeller, and the speed of rotation will become slower and slower, and the suction power will become smaller and smaller!

I haven't heard of this brand. You can find a distributor of this brand, if not, then find a manufacturer.

There are many reasons for the low suction power of the smoke machine: if it is newly installed and just used, check the installation height and the problem of the smoke exhaust pipe. The installation height is too high, and the suction power is not strong; The smoke exhaust pipe is too long and bent more, which will also affect the smoking effect, and the length of the smoke exhaust pipe is controlled within meters, and the number of bends is 1 time; If it has been used for a long time, it is recommended to clean the range hood.

If it still doesn't work, it is recommended to contact the manufacturer for after-sales inspection and processing.

Just find a way to get the wind out there! For example, connect a bend on the outside, with the mouth downward, so that the wind will not blow in easily, and it will not be flooded in on rainy days.

Quite simply, your range hood has been around for a while, is it a public flue? There is a return smoke check valve at the connection between the flue and the smoke pipe, and there is too much oil stain, resulting in the valve not being opened.
