Control method of refrigerator and refrigerator

Abstract

The invention provides a refrigerator, which comprises a door body, a refrigerator body, a circulating fan, temperature sensors, a refrigerating system and a controller, wherein chambers are defined in the interior of the refrigerator body; the chambers comprise a refrigerating chamber, a freezing chamber and a temperature-variable chamber; the circulating fan is arranged in the temperature-variable chamber, and runs when temperature differences of different areas in the temperature-variable chamber are bigger than a preset value or runs during the refrigerating process of the temperature-variable chamber; the temperature sensors are respectively arranged in the chambers so as to acquire the temperature of each chamber; the refrigerating system is used for refrigerating the chambers; the controller is used for controlling the refrigerating system to be started and stopped and the circulating fan to be started and stopped according to the acquired temperature. The refrigerator provided by the embodiment of the invention has the advantages that the temperature of the temperature-variable chamber can be accurately controlled, and the temperature fluctuation of the temperature-variable chamber is smaller, and therefore, the market competitiveness of the refrigerator is promoted. The invention also provides a control method of the refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator control method and the refrigerator. Background technique [0002] At present, there are direct cooling refrigerator products with variable greenhouses in the market, for example: traditional direct cooling three-door and multi-door products, the working range of variable greenhouses is in the range of -10℃~+10℃, and traditional variable greenhouses are generally designed in the middle door position, which is convenient for consumption Combined with the limitation of direct cooling products and direct cooling system and structure, the temperature of the variable temperature room changes drastically, and it is easily affected by the temperature changes of the refrigerator and freezer. The temperature of the variable temperature room fluctuates greatly and the temperature control is not accurate. Especially near zero, the temperature difference drifts...

Problems solved by technology

[0002] At present, there are direct cooling refrigerator products with variable greenhouses in the market, for example: traditional direct cooling three-door and multi-door products, the working range of variable greenhouses is in the range of -10℃~+10℃, and traditional variable greenhouses are generally designed in the middle door position, which is convenient for consumption Combined with the limitation of direct cooling products and direct cooling system and structure, the temperature of the variable temperature room changes drastically, and it is easily affected by the temperature change of the refrigerator and freezer. The temperature of the variable temperature room fluctuates greatly and the temperature control is not accurate.

Especially near zero, the temperature difference drifts greatly (that is, the temperature fluctuates greatly). For example, some existing refrigerators and variable temperature chambers can usually only achieve a temperature control accuracy of ±3°C
