Self-adapting rotary electric air door control method for refrigerator

Abstract

The invention discloses a self-adapting rotary electric air door control method for a refrigerator and relates to the technical field of refrigerator control. The self-adapting rotary electric air door control method comprises the following steps that firstly, when the refrigerator starts to refrigerate, the opening size of a rotary electric air door is 50% of the opening size in the fully openedstate; secondly, the cold chamber temperature T1 when the rotary electric air door of the refrigerator is opened and the cold chamber temperature T2 after a period of time t are detected and recorded,and the change amount delta T of the two temperatures is calculated, wherein delta T is equal to T1-T2; and thirdly, the delta T value is compared with the target value T, and the maximum opening size of the rotary electric air door is determined. According to the self-adapting rotary electric air door control method for the refrigerator, the maximum opening value of the rotary electric air dooris controlled by detecting the temperature variation of a cold chamber, so that the rotary electric air door can be installed in refrigerators with different capacity sections and meet the refrigeration requirements of the refrigerators with different capacity sections, and the standardization and generalization of the structural design of the refrigerator are improved; meanwhile, the cold air isreasonably distributed, the utilization rate of the cold air is increased, and thus the purpose of saving energy is achieved.

Description

technical field [0001] The invention belongs to the technical field of refrigerator control, in particular to an adaptive rotary electric damper control method for a refrigerator. Background technique [0002] With the increasingly fierce competition in home appliances, it is imperative to reduce product design costs. At present, the degree of standardization and generalization of product design is low, and the level of generalization of parts and components is insufficient, which directly leads to the high cost of individual parts and brings great pressure to reduce the total cost of products. [0003] Therefore, in response to this problem, the applicant proposed a method for controlling the self-adaptive rotary electric damper applied to refrigerators. Since the area of ​​the air outlet of the self-adaptive rotary electric damper is linearly adjustable, by controlling the rotary electric damper The maximum air outlet opening area is used to control the maximum air output...
