Embodiment Construction

[0022] A control system for anti-freezing of rotary electric damper blades, including a control module, the control module is used to receive the state information of the rotary electric damper monitored by the monitoring module, and transmit the state information to the timing module, and at the same time receive the data transmitted by the timing module and analysis; the monitoring module connected with the control module and used to detect the state of the rotary electric damper; the timing module connected with the control module and used for timing the state maintenance time of the rotary electric damper, and the timing module can receive the rotary electric damper sent by the control module. The status information of the damper, and start the timing action, and send the timing data to the control module at the same time; and the heating wire connected to the control module. Freezing; the rotary electric damper is installed inside the air duct, and the damper is opened and...

Abstract

The invention discloses an anti-freezing method for blades of a rotary electric air door, and relates to the technical field of electric air doors of refrigerators. The anti-freezing method comprises the following steps that the refrigerator is powered on, the control system operates, and the monitoring module monitors the state of the rotary electric air door; the opening state of the electric air door and the duration of maintaining the secondary state are judged; and when the duration time is larger than the preset value, the control module controls the rotary electric air door to execute the anti-freezing instruction. By timely controlling the action of the blades of the rotary electric air door and reasonably starting the heating wire of the rotary electric air door, the problem that the existing blades are frozen at low temperature is effectively solved, and normal work of the rotary electric air door is ensured.

Description

technical field [0001] The invention belongs to the technical field of electric dampers of refrigerators, and in particular relates to a method for preventing freezing of blades of rotary electric dampers. Background technique [0002] Electric dampers have been widely used in air-cooled frost-free refrigerators. At present, the more common electric dampers are opened and closed through the rotation of the door shaft to drive the door panel. The electric damper has two states: closed and open, and the maximum opening angle is 90 degrees. In order to ensure the normal switching of the electric damper, a large space needs to be reserved for the air duct where the electric damper is installed, which will also cause a waste of space for the refrigerator. [0003] For example, Chinese Publication No. CN211406312U discloses a damper antifreeze device and an antifreeze damper, which includes a heating belt, the outer side of the heating belt is covered with an insulating layer, and...
