Background

Currently, a common air-cooled refrigerator generally uses an electric damper to control the temperature of its refrigerating chamber. The structure of the air door is shown in figure 1: when the temperature of the refrigerating chamber is too high and refrigeration is needed, the air door driving motor drives the reduction gear to trigger the electric air door plate to rotate and open so as to enable cold air to flow into the refrigerating chamber; when the temperature of the refrigerating chamber reaches the preset temperature, the air door driving motor runs reversely to drive the electric air door plate to rotate and close through the transmission in the gear box, and the refrigerating chamber stops refrigerating. Refrigerator power dampers typically require only two states, open and closed. It realizes the air door drive through step motor usually, drives drive gear in order to control opening and closing of electronic air door plant through step motor's positive and negative rotation.
