Problems solved by technology

When the temperature collected by the temperature sensor 110' is extremely high, the temperature collected by the temperature sensor 110' is always higher than the start-up temperature of the compressor 130', so that the compressor 130' is always on, which affects the life of the refrigerator, and the actual The temperature will become very low, and the freezer may freeze
When the temperature collected by the temperature sensor 110' is extremely low, the temperature collected by the temperature sensor 110' is always lower than the shutdown temperature of the compressor 130', and the compressor 130' keeps shutting down, causing the actual temperature of the compartment to gradually increase until reaching room temperature, making the functions of the refrigerator such as fresh-keeping and freezing invalid

Abstract

The invention provides a compartment temperature control method of a refrigerator. The compartment temperature control method comprises the following steps of: receiving a first temperature signal detected by a temperature sensor in a compartment of the refrigerator, and judging whether the first temperature signal is in a first temperature interval; if the first temperature signal is in the first temperature interval, judging that the temperature sensor is in a normal state, and controlling a compressor to be started or stopped in a preset way according to the first temperature signal; and if judging that the first temperature signal is not in the first temperature interval, judging that the temperature sensor has a fault, and controlling the compressor to be started and stopped according to a preset stop / start time rate. According to the embodiment of the invention, when the temperature sensor has the fault, the compressor can be controlled to be started and stopped normally so as to prevent the compartment temperature fluctuation from being overlarge, and compartment function failure is avoided.

Description

Technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a method for controlling the temperature of a refrigerator compartment. Background technique [0002] At present, electronically controlled refrigerators collect the temperature of each compartment of the refrigerator through a temperature sensor to control the on and off of the compressor, thereby controlling the temperature of the compartment. If the temperature sensor fails, the compressor of the refrigerator will always be turned on or stopped, making the room temperature of the refrigerator too low or too high, thus affecting the freshness and freezing functions of the refrigerator. And if the compressor is turned on for a long time, it will affect the life of the compressor. [0003] The start and stop of the refrigerator compressor is controlled by the temperature sensor collecting the temperature of the compartment. Such as figure 1 As shown, the temperature se...
