[0051] This embodiment provides an automatic cleaning method for range hoods, such as Figure 1 to Figure 2 As shown, the range hood V of this embodiment includes a volute 1 , an oil collecting device 2 for collecting grease, an impeller 3 inside the volute 1 and a motor 4 for driving the impeller 3 to rotate. When the range hood V works in the smoking mode to take away the oil fume generated in the cooking process and discharge it outside, the motor 4 drives the impeller 3 to rotate.
[0052] Combine below image 3 The automatic cleaning method of the range hood in this embodiment is introduced. like Figure 1 to Figure 3 As shown, the automatic cleaning method of the present embodiment includes:
[0053] Step S1: Drive the impeller 3 to reverse to throw at least part of the grease on the impeller 3 onto the volute 1. The rotation of the impeller 3 during reverse rotation is opposite to that of the range hood V in the smoking mode.
[0054] Step S2: heating the volute 1 t...

[0111] The difference between the second embodiment and the first embodiment is: in the automatic cleaning method of the range hood of the second embodiment, continue to refer to Figure 1 to Figure 2 As shown, before heating the volute 1, the impeller 3 is driven to reverse A times, A is less than N; then, while the volute 1 is heated, the impeller 3 is driven to reverse B times, A+B=N, that is, the volute The starting time of heating 1 is not later than the starting time of the penultimate B reverse rotation of the impeller 3, and the stopping time of the heating of the volute 1 is not earlier than the stopping time of the last reverse rotation of the impeller 3.
[0112] In the first variation example of this embodiment, before the volute 1 is heated, the driving impeller 3 is reversed A times, A is less than N; then, after the volute 1 is heated, the driving impeller 3 is reversed C times, A+ C=N, that is, the stop moment of heating of the volute 1 is not earlier than the ...

[0122] The difference between the third embodiment and the first embodiment is: in the automatic cleaning method of the range hood of the third embodiment, continue to refer to Figure 1 to Figure 2 As shown, while the volute 1 is being heated, the impeller 3 is driven to reverse B times, and B is equal to N, that is, the starting time of the volute 1 being heated is not later than the starting time of the first reverse rotation of the impeller 3, and the volute The heating of the casing 1 is stopped no earlier than the last reverse rotation of the impeller 3 .
[0123]In the technical solution of this embodiment, on the one hand, at least part of the grease on the impeller 3 will be thrown onto the volute 1 under the action of centrifugal force during the reverse rotation, thereby realizing the cleaning of the impeller 3 . On the other hand, while heating the volute 1, the impeller 3 is driven to reverse, and the remaining grease on the impeller 3 can be thrown onto the volut...
