How to control the refrigerator

Abstract

The invention provides a refrigerator and a control method of the refrigerator. The refrigerator comprises a temperature changing chamber, a refrigeration system, an air flue, a fan, a controller, a heating element, a first temperature sensor and a second temperature sensor. The heating element is arranged in the air flue, the first temperature sensor is arranged on the upper side of the temperature changing chamber and used for sensing the temperature of the upper side of the temperature changing chamber, and the second temperature sensor is arranged on the lower side of the temperature changing chamber and used for sensing the temperature of the lower side of the temperature changing chamber. When a self-freezing mode of the temperature changing chamber is transformed to be a cold storage mode or an ice temperature mode, on one hand, the heating element and the fan are started, heat is provided for the temperature changing chamber, switching time of the temperature changing chamber is shortened, and convenience is brought to a user for use; on the other hand, when the temperature difference between the temperature sensed by the first temperature sensor and the temperature sensed by the second temperature sensor is higher than a first preset temperature difference, the controller controls the heating element to halt, the fan continues to operate to make the temperature in the temperature changing chamber uniform, and food in the temperature changing chamber can be kept fresh.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a control method for a refrigerator capable of preventing uneven temperature in the variable temperature chamber during the process of switching from the freezing mode to the refrigeration mode or ice temperature mode in the variable temperature chamber. Background technique [0002] Refrigerator is one of the essential household appliances in many families, which provides convenience for people's life. With the development of refrigerator technology and the diversification of consumer demand, refrigerators with variable temperature chambers have appeared to meet consumer demand.

Problems solved by technology

[0003] Existing refrigerators with temperature-changing chambers, in the process of converting from the self-freezing mode to the refrigerating mode or the ice-temperature mode, partly convert the refrigerator into the refrigerating mode or the ice-temperature mode through natural heat exchange, but the downtime is too long , unable to meet the timely needs of users; the other part is to set heating elements in the temperature-changing room to provide heat to the temperature-changing room in the process of changing the self-freezing mode of the temperature-changing room into a refrigerating mode or ice temperature mode, so that the inside of the temperature-changing room However, it is easy to cause local overheating in the variable room, and the temperature sensed by the temperature sensor in the variable temperature room is inaccurate.
