Everyone may feel distressed about the oil fume problem in the kitchen, but Xiao Bian believes that it must be because we didn't choose a suitable range hood, or because we didn't clean and maintain it regularly during the later use. Therefore, today, I will introduce the maintenance methods of the range hood, including the cause analysis and troubleshooting suggestions. From this, we can know that the range hood has been used for a long time or its own unreliable quality, which is likely to make the later products wear out or cause troubles that it can't absorb the lampblack. At this time, it is necessary to check the operation, that is, analyze and eliminate the faults in combination with the above, so as to obtain a reasonable and reliable maintenance solution to maximize the use value of the range hood itself.

1. Maintenance method of range hood

Repair of range hood-poor oil smoke extraction effect

Cause analysis and treatment: the installation point is too high from the stove, so lower the installation point appropriately; If the exhaust pipe is too long or the air outlet direction is improperly selected, shorten the exhaust pipe appropriately and re-select the air outlet direction; If the sealing strip fails and leaks, replace the sealing strip to seal it tightly; If the internal circulating activated carbon fails, replace it; If the pressure difference between indoor and outdoor is too large, properly open doors and windows to reduce the pressure difference between indoor and outdoor; If the voltage is too low, a voltage regulator should be configured if necessary; The air intake passage is blocked by oil pollution, so clean the oil pollution.

Repair of range hood-failure of key switch

Cause analysis and treatment: If the key switch can be locked by pressing it, and the motor cannot be started by pressing all gears, the public * * * connection will be disconnected, and it will be found out and welded again; If the motor can't run when one gear is pressed, and the other gear is normal, it means that only the contact of the out-of-control gear is damaged or the step connection is broken, and the contact and connection should be repaired; If the switch motor can run when the key is pressed, the key can't be locked after being released, mainly because the conductive spring in the switch is deformed and can't contact with the conductive piece, or the switch spring piece is displaced or falls off, the spring piece should be adjusted or replaced with a new switch; If the key switch is pressed and both gears are locked, it means that the interlocking spring is deformed and displaced by extrusion, and the interlocking spring should be adjusted and repaired.

Repair of range hood-range hood affects the heat of cooking fire source

Causes and analysis: excessive selection of exhaust air volume causes heat waste and prolongs heating time, so it is necessary to properly select exhaust air volume; The range hood is installed too low, so the height of the range hood should be raised appropriately.

repair of the range hood-the range hood is seriously dirty

Cause analysis and treatment: if the range hood is not cleaned in time, it should be cleaned and tested in time; If the air duct is not cleaned, after the power is cut off, open the cover, take out all baffles and filter screens, clean them and install them.

repair of range hood-touch switch is not working

cause analysis and treatment: replace the switch glass plate.

Repair of range hood-unable to start after being electrified

Cause analysis and treatment: the power cord is broken or the connector is off-welded, carefully find out the broken point or off-welded point and re-weld; If the on-off switch is open or the contact is poor, check whether the circuit breaker is welded well, and replace it with a new one if the contact is poor; The capacity of the starting capacitor of the motor is reduced or it is short-circuited or open-circuited, which requires replacing the capacitor with the same specification to make the motor run; The variable speed coil is open or short-circuited, and the variable speed coil is repaired or replaced with new products; The bearing is damaged and stuck on the rotating shaft, so the bearing must be replaced; The stator winding is short-circuited or the connecting wire is broken. Repair the stator winding or replace it with a new one.

Repair of range hood-abnormal sound or loud noise during operation

Cause analysis and treatment: improper assembly makes the fan blade loose and touches the air guide frame to generate abnormal sound, so reassemble and tighten the fan blade fastening nail correctly; The motor bearing is seriously worn, so the bearing of the same model must be replaced; If the motor is poorly assembled, correct the gap between the stator and rotor of the motor to make it even. If there is axial movement, appropriate washers should be added; The deformation of the fan blades is unbalanced, correct the fan blades, and adjust the dynamic and static balance of the fan blades; The design of air outlet pipeline is unreasonable. The air outlet pipe should turn as little as possible, and the turn should be large and round.

Repair of range hood-excessive vibration of range hood

Cause analysis and treatment: weak fixation or poor installation, and firm fixation with rubber pad or foam plastic; There are foreign bodies on the blades and the internal dirt is too thick. Remove the foreign bodies and internal dirt on the blades; The spindle and blade sleeve are eccentric, and the spindle and blade sleeve are readjusted to be concentric; If the motor bearing is worn or the bearing hole is too large, replace it with a new bearing of the same specification; The motor winding is partially short-circuited or open-circuited. Replace the winding or motor.

Repair of range hood-oil leakage

Cause analysis and treatment: improper installation, insufficient elevation angle, re-installation, so as to keep a certain elevation angle, so that the sucked oil naturally flows down the oil cup smoothly; Or add a filter screen at the air outlet with a certain angle, so that oil droplets cannot drip under the action of surface tension; If the sealing strip fails for a long time, add rubber or foam plastic strips at the sealing place to compact the parts and improve the sealing level; If it is not cleaned regularly, the oil dirt in the oil cup should be removed frequently and the filter screens and pipelines should be cleaned to avoid the overflow of smoke and oil dirt.
