Air-cooled refrigerator control method, air-cooled refrigerator control device, and air-cooled refrigerator

Abstract

The invention relates to a control method of an air-cooled refrigerator, a control device of the air-cooled refrigerator and the air-cooled refrigerator. The control method of the air-cooled refrigerator is applied to a compressor, a fan, an evaporator, an air duct, a freezing chamber and the air-cooled refrigerator with a refrigerating chamber; the control method of the air-cooled refrigerator comprises the following steps that whether the fan is in a starting state or not is judged when the temperature of the refrigerating chamber is higher than a first adjusting temperature of the fan, if the fan is not in the starting state, then the fan is controlled to be started, and the rotating speed of the fan is controlled to be a working rotating speed; when the temperature of the refrigeratingchamber is located between a second adjusting temperature and a third adjusting temperature of the fan and the compressor is in a stopping state, and the fan is controlled to be stopped. The controlmethod of the air-cooled refrigerator, the control device of the air-cooled refrigerator and the air-cooled refrigerator effectively controlled the temperature of the refrigerating chamber of the air-cooled refrigerator and the temperature of the freezing chamber, the use effect of a user is guaranteed, the working cost of refrigerator refrigeration is saved, a refrigeration electric air door is omitted, and the overall cost of the air-cooled refrigerator is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerator refrigeration, in particular to a control method for an air-cooled refrigerator, a control device for an air-cooled refrigerator, and an air-cooled refrigerator. Background technique [0002] The air-cooled refrigerator is powered by a fan, so that the air in the refrigerator compartment flows through the evaporator to reduce the temperature, and then the cold air is sent to the refrigerator and freezer through the air duct, so that the temperature of the refrigerator compartment is lowered. Since the refrigerator compartment and the freezer compartment are cooled by the cold air sent into the compartment, the temperature of the refrigerator compartment can be controlled by controlling the air supply volume of the refrigerator compartment. [0003] When the refrigerator works according to a set gear, the temperature of the refrigerator compartment should remain unchanged under different ambie...

AI Technical Summary

Problems solved by technology

[0004] There are two main methods for controlling the air supply ratio of the refrigerator and freezer in the air-cooled refrigerators currently on the market: the first method is to control the air supply volume of the refrigerator by controlling the opening and closing of the electric damper of the refrigerator through sensors, thereby controlling The air supply ratio of the two compartments of the refrigerator, but because this method uses an electric damper, the cost is relatively high

The second is to change the air supply volume of the refrigerator room by manually adjusting the opening size of the mechanical air door of the refrigerator room, thereby controlling the air supply ratio of the two compartments of the refrigerator; however, the mechanical air door needs to be adjusted manually, and the opening size cannot be adjusted automatically. make the user experience poor
