Refrigerator and method for controlling electric damper of refrigerator

Abstract

The invention relates to a method for controlling an electric damper of a refrigerator. The method is characterized by comprising firstly, acquiring environmental temperatures T<H>; secondly, comparing the environmental temperatures T<H> to reference environmental temperatures T<reference> to determine environmental temperature intervals of the environmental temperatures T<H>; thirdly, controlling the electric damper of the refrigerator according to the environmental temperatures T<H>, temperatures T<chamber>, temperatures T<target>, the reference environmental temperatures T<reference>, temperatures T1<reference>, temperatures T2<reference> and experimental measured values a<degree>, c<degree>, d<degree>, t1<MIN>, t2<MIN>, b<degree>, e<degree>, f<degree>, t3<MIN> and t4<MIN>. The invention further relates to the refrigerator. The method is used for controlling the electric damper of the refrigerator. The method and the refrigerator have the advantages that the running reliability of the refrigerator with the controlled electric damper can be improved in different regions and different seasons, and 'the deviation between the chamber temperatures and the target temperatures' can be within a small range under the effective and stable control in real time.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a method for controlling an electric damper of a refrigerator and a refrigerator adopting the method. Background technique [0002] At present, there are only two states for the control of the electric damper of the refrigerator: fully open or fully closed. In terms of the control of the electric damper of the refrigerator, there are two factors that affect the performance of the refrigerator: on the one hand, the external ambient temperature (hereinafter referred to as the ambient temperature); on the other hand, the internal "deviation between the room temperature and the target temperature" . Among them, the ambient temperature, as a factor that is relatively stable outside and changes slowly, determines the benchmark for the refrigerator's control operation, and the internal "deviation between the room temperature and the target temperature" is greatly affected by the operating ...

AI Technical Summary

Problems solved by technology

Under the control logic of the electric damper of the existing refrigerator, that is: fully open when it is opened and fully closed when it is closed, it will easily lead to the following phenomenon: when the ambient temperature is low, the damper is fully opened and the room temperature is too cold. When the ambient temperature is high, the damper is fully closed, causing the room to overheat, which in turn increases the risk of food spoilage

[0004] Regarding the "deviation between the compartment temperature and the target temperature": as a refrigeration system, the refrigerator is nothing more than to make the compartment temperature as close as possible to the target temperature. There are many factors that affect the "deviation between the compartment temperature and the target temperature", including: Defrost in the compartment, opening the door, putting food in, changing the target temperature, etc., these factors can easily cause the "deviation between the compartment temperature and the target temperature" to be too large, and the original damper control mode, the simple switch cannot be real-time, Effectively and stably control the "deviation between the compartment temperature and the target temperature" within a small range
