Problems solved by technology

Since the electronic damper itself generally does not have a dedicated position sensor, it cannot sense whether the damper has moved to the required position
If the damper does not operate properly, it will affect the air supply control of the cooling room, resulting in the cooling unable to meet the demand

Embodiment Construction

[0027] This embodiment provides a method for controlling the electronic air door, which is used to control the electronic air door of the air-cooled refrigerator to improve the reliability of the electronic air door. figure 1 It is a schematic diagram of a control method of an electronic damper according to an embodiment of the present invention. Such as figure 1 As shown, the control method includes:

[0028] Step S102, obtaining a control instruction for controlling the electronic damper;

[0029] Step S104, driving the electronic damper to execute the switching action according to the control instruction;

[0030] Step S106: Detect the temperature change trend in the compartment where air is supplied through the electronic damper;

[0031] Step S108, judging whether the temperature change trend matches the temperature adjustment target of the switch action;

[0032] Step S110, if not, control the electronic damper to perform a reset operation and return to step S106; if yes, perform...

Abstract

The invention provides a control method and device of an electronic air door. The control method of the electronic air door comprises the steps of acquiring a control command used for controlling the electronic air door; driving the electronic air door to perform opening and closing action according to the control command; detecting the temperature variation trend in a chamber of which the air is supplied from the electronic air door; judging whether the temperature variation trend is matched with a temperature regulation objective of the opening and closing action or not; and if not, controlling the electronic air door to perform reset action. According to the control method and device of the electronic air door, after the electronic air door is driven to perform the opening and closing action, the temperature variation trend in the chamber of which the air is supplied from the electronic air door is detected, whether the temperature variation trend conforms to the temperature regulation objective of the electronic air door action or not is judged, and when the temperature variation trend does not conform to the temperature regulation objective of the electronic air door action, the electronic air door is driven to perform reset action, so that the situation that the refrigeration of an air-cooled refrigerator is influenced by abnormal air supply due to the fact that the air door does not move in place is avoided, and the reliability of the electronic air door is improved.

Description

Technical field [0001] The invention relates to the control of household electrical appliances, in particular to a method and device for controlling an electronic damper. Background technique [0002] With the popularization of air-cooled refrigerators, electronic dampers are more and more widely used in refrigerators. The electronic air door uses a stepping motor to drive the air door baffle through a gear reduction to achieve air supply control to the compartment that needs cooling. [0003] From the closed state to the opening of the damper, the stepper motor is required to perform a fixed number of running steps. Similarly, the stepper motor is required to run a fixed number of steps in the opposite direction from opening to closing. In the prior art, when the compartment needs to be cooled, the control board controls the stepper motor to open the damper according to the number of steps opened; when the compartment does not require cooling, the control board controls the stepp...
