[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...

Abstract

The invention discloses a kitchen appliance, a range hood and an automatic cleaning method of the range hood. The cleaning method comprises the steps that an impeller (3) is driven to rotate backwards, at least part of oil on the impeller (3) is thrown to a volute (1), and the rotation direction when the impeller (3) rotates backwards is opposite to the rotation direction of the impeller (3) in a smoke exhaust mode of the range hood (V); and the volute (1) is heated, so that the oil attached to the volute (1) is molten and then flows into an oil collection device (2). By driving the impeller (3) to rotate backwards and heating the volute (1), cleaning of the impeller (3) and the volute (1) is achieved, and the internal cleaning effect of the range hood (V) is improved.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a kitchen appliance, a range hood, and an automatic cleaning method for the range hood. Background technique [0002] The range hood is a kind of kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove. It can quickly remove the waste burned by the stove and the harmful oil fume generated during the cooking process, and discharge it outdoors to reduce pollution and purify the indoor air. During the use of the range hood, grease is most likely to adhere to the volute and impeller inside the range hood. If it is not cleaned effectively for a long time, the grease will accumulate more and more, and the grease will be difficult to clean due to oxidation and air drying. In addition, the accumulation of excessive grease on the impeller will increase the weight of the impeller and thus increase the load on the motor driving the impelle...
