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.
