Problems solved by technology

These two methods have a certain cleaning effect, but there are also problems: (1) the oil on the back of the blade cannot be completely removed; (2) the cost increases too much; (3) water cleaning needs to be added regularly, winter It may be necessary to heat the water to achieve good results
As previously mentioned, the existing automatic cleaning methods are not satisfactory, and designing a low-cost, easy-to-operate automatic cleaning device and corresponding methods is a problem to be solved in this area

Embodiment 1

[0022] The following is attached figure 1 , 2 The present invention is described in further detail with regard to using single-phase AC motor:

[0023] refer to figure 1 , an automatic cleaning device for range hoods, including a motor M for driving the impeller, a forward and reverse control circuit for the motor, and a forward and reverse control circuit for driving the motor to perform several preset cycles of alternating forward and reverse rotations after the motor works for a set time. The cycle further drives the controller IC1 for automatic centrifugal cleaning of the impeller.

[0024] In order to facilitate the user to start the automatic cleaning program at any time, it also includes an automatic cleaning operation switch S4 that manually sends instructions to the controller to drive the motor through the forward and reverse control circuit to perform several preset cycles of forward and reverse alternate cycles. In addition, there are start switch S1, wind speed...

Embodiment 2

[0038] In this embodiment, the motor adopts a DC brushless motor, combined with the attached image 3 , 4 The present invention is described in further detail:

[0039] refer to image 3 , the range hood self-cleaning device, also includes the motor for driving the impeller, the forward and reverse control circuit of the motor, and the forward and reverse control circuit for driving the motor to perform several preset cycles of alternating forward and reverse after the motor works for a set time The controller that circulates and then drives the automatic centrifugal cleaning of the impeller. The difference is that its motor is a DC brushless motor, and its three-phase running winding is connected to the output end of the controller through a PWM drive circuit. The U-phase and V-phase in the running winding And a braking resistor is connected between the U phase and the W phase through the same internal braking relay with a double-pole single-throw switch, and the control te...

Abstract

The invention provides a device for automatically cleaning an extractor hood. The device comprises a motor, a motor forward-reverse rotating control circuit and a controller, wherein the motor is used for driving an impeller, and the controller is used for driving the motor to rotate forward and reversely in an alternating mode within preset periods through the forward-reverse rotating control circuit after the motor operates for the preset time, and then driving the impeller to automatically clean the extractor hood in a centrifuging mode. The device has the advantages that the motor is controlled through the forward-reverse rotating control circuit to circularly rotate forward and reversely in the alternating mode, the motor drives a turbine and blades of the extractor hood to rotate forward and reversely, greasy dirt on the blades fast falls from the blades based on the principle of movement inertia, and accordingly the self-cleaning purpose is achieved; the device is low in machining cost, convenient to operate and reliable in operation.

Description

technical field [0001] The invention relates to the field of kitchen appliance control, in particular to a self-cleaning device and method for a range hood. Background technique [0002] In the prior art, the internal cleaning of the range hood mainly focuses on the cleaning of the turbine and the blades. There are two common methods. One is to add a heating pipe to the volute to increase the oil temperature in the volute to make it easy to clean. Another way to get rid of the impeller is to increase the water cleaning, that is, use the pump to spray water on the impeller to rinse the impeller. These two methods have a certain cleaning effect, but there are also problems: (1) the oil on the back of the blade cannot be completely removed; (2) the cost increases too much; (3) water cleaning needs to be added regularly, winter Sometimes it may be necessary to heat the water to achieve good results. [0003] The current motors used in range hoods are generally single-phase AC ...
