Problems solved by technology

However, the stepper motor cannot be directly connected to the DC power supply, but must be driven by a dedicated stepper motor driver chip (such as Toshiba TA7774P) on the main control board, or driven by a dedicated stepper motor driver and controller.
It is more complicated in terms of drive circuit and control, and the manufacturing cost is relatively high

Embodiment Construction

[0011] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0012] If the DC motor can be used to control the electric damper of the refrigerator, compared with the stepping motor, it can be directly driven by the DC power supply, which improves the safety and will not cause accidents such as fire, and does not need to use special stepping motor drivers and other components. However, the DC motor rotates at a high speed, and there are practical problems to be solved to drive the air door of the refrigerator with it.

Abstract

The invention discloses a refrigerator electric damper control device driven by a direct current motor. The refrigerator electric damper control device comprises the direct current motor and a speed reduction mechanism, wherein the speed reduction mechanism is connected with the direct current motor and acts on an irregular gear used for controlling the opening degree of a damper baffle. The refrigerator electric damper control device has the advantages that the direct current motor driven by a direct current power source is adopted to control the damper baffle and is matched with the speed reduction mechanism to form a control device of a refrigerator electric damper. The refrigerator electric damper control device is simple in whole structure, high in safety and convenient to control, and enables the refrigerator electric damper to be driven by the direct current motor instead of a stepping motor.

Description

technical field [0001] The invention relates to an electric damper of a refrigerator, in particular to a control device for the electric damper of a refrigerator. Background technique [0002] With the further development of electronic temperature-controlled refrigerator control technology, stepper motors are used to control the damper baffle in the existing refrigerator electric damper, and its rotating speed is usually 200-500r / min. However, the stepper motor cannot be directly connected to the DC power supply, but must be driven by a dedicated stepper motor driver chip (such as Toshiba TA7774P) integrated on the main control board, or driven by a dedicated stepper motor driver and controller. It is more complicated in terms of driving circuit and control, and the manufacturing cost is relatively high. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of the present invention is to provide a control device for the el...
