How to clean the big range hood in the hotel

Hotel kitchen lampblack machine is an electrical product that people use to solve the problem of kitchen lampblack. However, if it is used for a long time, the surface and inner cavity of the kitchen range hood will be full of oil pollution, which will affect its normal smoke exhaust effect. Only when it is disassembled and cleaned correctly can it be used normally. Generally, the cleaning process of kitchen range hood without filter screen cover is as follows:

1. First cut off the power supply of the range hood in the hotel kitchen to ensure personal safety.

2. The shell surface and net cover of the range hood in the hotel kitchen are generally cleaned according to the cycle specified in the manual, and scrubbed with a soft cloth with warm water stained with a small amount of neutral detergent. Then dry it with a dry soft cloth.

3. Disassembly and cleaning of impeller and volute cavity

(1) Unscrew the screws of the cover plate and net cover, and remove the cover plate and net cover.

(2) Then unscrew the fastening screw of the wind wheel and take out the wind wheel.

(3) Soak the removed parts in warm water containing neutral detergent, clean them with a soft cloth and dry them.

(4) Dip a small amount of warm water containing neutral detergent with a soft cloth to scrub the dirt in the inner cavity of the volute, and then dry it after cleaning with a soft cloth.

(5) Assemble the above components in the reverse order of disassembly.

(6) After installation, check whether the oil circuit of the appliance is unblocked and whether the sealing ring on the volute can be sealed.

(7) Please clean the wind wheel, volute, oil nozzle and oil drain pipe according to the cycle specified in the manual.

4. Precautions for cleaning impeller and volute:

(1) When cleaning, water cannot enter the motor and electrical components.

(2) When cleaning, do not pull the internal connecting wire, otherwise it will loosen the connecting point and cause electric shock.

(3) It is forbidden to use flammable solvents such as alcohol, banana oil and gasoline to clean the range hood in the hotel kitchen to prevent fire accidents.

(4) When cleaning, wear rubber gloves to prevent sharp edges of metal parts from hurting people.

(5) Handle the removed parts carefully to avoid deformation. Be especially careful when cleaning the impeller. Do not touch or move the counterweight of the blade, otherwise the whole machine will vibrate and the noise will increase. For those range hoods with filter screens, because the kitchen oil fume of the hotel has been filtered before entering the interior of the electric appliance, its internal structure does not need to be cleaned, and only the electric appliance shell and filter screen cover need to be cleaned regularly according to the instructions.

5. Cleaning of filter screen cover.

(1) Unscrew the screw for fixing the net cover.

(2) Soak the removed filter screen cover in warm water of neutral detergent for 5- 10 minutes.

(3) Clean the dirt in the pores of the filter with a soft plastic brush, and then dry it with a dry rag.

(4) Install the filter screen cover as it was before disassembly.

(5) After installation, check whether the oil circuit of the appliance is unblocked and whether the sealing ring on the volute can be sealed.

Please clean the filter screen cover according to the cycle specified in the manual.

The internal electrical connection and airflow seal of the kitchen lampblack machine in the hotel should not be disassembled and cleaned frequently. The sealing ring is often disassembled and cleaned, which may easily lead to aging and deformation. Oil stains easily enter the electrical connection parts of electrical appliances, affecting their safety performance and reducing the service life of kitchen range hoods in hotels.
