Device and method for cleaning fume exhauster

Abstract

The invention provides a lampblack absorber cleaning device. The invention is characterized by comprising a cleaning process controller, wherein, the cleaning process controller consists of a wind wheel totating speed control module and a water pump switch control module; the output terminal of the wind wheel totating speed control module is connected with a motor to transmit different totating speed signals to the motor, and the motor rotates at totating speed corresponding to the totating speed signals; an output terminal of the water pump switch control module is connected with the water pump to transmit switch signals to the water pump, and the water pump is switched on or off according to the switch signals. The invention also provides a cleaning method for a lampblack absorber cleaning device, which includes the following steps: the motor is started; the motor drives the wind wheel to rotate at high speed; the motor drive the wind wheel to rotate at low speed; the water pump is turned on and cleaning fluid is spouted from a cleaning nozzle; the motor drives the wind wheel to rotate at medium speed; the water pump is turned off and the cleaning nozzle stops spouting cleaning fluid; the motor drives the wind wheel to rotate at high speed to dry the wind wheel; the motor is turned off and the cleaning process is finished. The invention has the advantages that the cleaning is complete, and the cleaning effect is good; the cleaning process is controlled through the cleaning process controller, therefore, the cleaning efficiency is high, and the use is convenient; in addition, the leakage of cleaning fluid is avoided.

Description

[0001] Field: [0002] The invention relates to a cleaning device for a range hood and a cleaning method thereof. Background technique: [0003] After the kitchen range hood has been used for a period of time, oil stains will adhere to the fan wheel of the range hood and the fume exhaust flue, especially the more oil stains on the wind wheel. If it is not cleaned in time, it will affect the performance of the range hood. Effect. [0004] At present, a cleaning device is installed on most range hoods. As shown in Figures 1 and 2, the cleaning device generally includes a water tank 11 for containing cleaning fluid, a water pump 12, a water supply pipe 13, a wind wheel 15 and a driving wind turbine. The motor 16 of the wheel 15, the water inlet of the water pump 12 is connected with the water tank 13, the water outlet of the water pump 12 is connected with the water inlet of the water supply pipe 13, the water outlet of the water supply pipe 13 is provided with a cleaning nozzle...

Problems solved by technology

As shown in Figure 1, when the motor 16 rotates at too high a speed, the cleaning liquid ejected from the cleaning nozzle 14 cannot reach the inside of the wind wheel 15 at all, and the cleaning area is limited, and due to the high rotating speed, part of the cleaning liquid is easily drawn out of the range fume body 1 In addition, it causes water dripping outside the body of the range hood 1; as shown in Figure 2, when the 4 mo
