What is the reason why hotel range hoods don't smoke?

1. The partition in the middle of the exhaust pipe is not straight or open, or the exhaust pipe is artificially blocked. Maintenance method: straighten or open the partition, or remove the sundries in the exhaust pipe. 2. The wind wheel is reversed or damaged. Maintenance method: the wind wheel needs to be disassembled and reassembled before it can be reversed. If it is damaged, it is recommended to replace the wind wheel. 3. The exhaust pipe is blocked. Maintenance method: clean the sundries in the smoke exhaust pipeline. 4. The capacitor is damaged, which causes the motor of the range hood to rotate reversely, and the smoke cannot be smoked. Maintenance method: replace the capacitor. 5. The motor is damaged, the power decreases, or the exhaust pipe is too long, and the resistance increases too much, resulting in no smoke. Maintenance method: It is recommended to replace the motor. Cleaning of the surfaces of various parts of the range hood: Wipe the surfaces of the range hood with a soft cloth and neutral detergent, and be careful not to use strong corrosive detergent to prevent damage to stainless steel panels and other components. Cleaning the oil box The cleaning of the oil box can be prepared in advance: stick a layer of cling film or put a small plastic bag on the box to ensure that the plastic film or plastic bag completely covers the inner surface of the box and can hold the adsorbed waste oil. Then, the oil storage box is pumped every once in a while for replacement, which is basically clean. Clean the oil net. Slowly remove the oil net with a screwdriver, and put the removed oil net in warm water of neutral detergent for 5- 10 minutes. Then use a soft plastic brush to clean the dirt in the pores of the filter screen, and then dry it with a dry rag. If the oil on the oil net is thick, you can also gently scrape off some oil with thin bamboo pieces before cleaning. Fan blade cleaning The cleaning of the fan blades of the range hood can be sprayed with cleaning liquid such as oil fume net. After a few minutes, the oil fume net and the dissolved oil are sucked away by the fan, and then cleaned with a rag. In addition, you can carefully remove the fan blades, soak them in hot water mixed with homemade detergent and vinegar for about 15 minutes, and then scrub them with a rag.
