Problems solved by technology

The temperature of each room of a household refrigerator is different, and during the heat preservation (maintenance) period of the refrigerator (most of the working time of the refrigerator belongs to the heat preservation time), the demand for cooling capacity of each room is certain, and the existing The refrigerator in the technology makes full use of the cold energy that the evaporator needs to absorb for defrosting to cool the cold room very little, resulting in a waste of energy

Embodiment Construction

[0031] Referring to the accompanying drawings, the flow of the control method of the present invention is as follows: first power on the refrigerator, and after the refrigerator is initialized, the temperature sensor starts to detect the temperature of each compartment of the refrigerator to detect whether there is a compartment that requires the compressor to be turned on. If there is no request to start up, the temperature detection will continue. If there is a request to start up, the main CPU will control the compressor to turn on. If the freezer and refrigerator require to be started at the same time, the compressor will run at high speed, and the temperature sensor will detect the temperature of the evaporator at the same time. Whether TZ is lower than the refrigerator temperature TR, if it is not lower, continue to detect, if it is lower, the main CPU will control the door of the refrigerator to open, the refrigerator fan runs at low speed, and the temperature sensor dete...

Abstract

The invention relates to a control method for refrigerator, concretely, it relates to control method for a frequency variable refrigerator, the invention provides a method for time division work of freezing chamber and cold storage chamber in the process of temperature control, and through the cold quantity demands estimation, the frosting process includes the refrigerating process of the cold storage chamber. The variable frequency refrigerator includes: primary CPU, freezing chamber, cold storage chamber, temperature sensor, compressor, the invention introduces the concepts of temperature change rate and target approaching rate, the refrigerator can adjust the temperature change of the refrigerator according to the rate.

Description

technical field [0001] The invention relates to a control method of a refrigerator, in particular to a control method of an inverter refrigerator. Background technique [0002] Air-cooled refrigerators in the prior art generally include: a main CPU, an inverter compressor, a temperature sensor, etc. The refrigerators in the prior art all detect the temperature of the refrigerator compartment or freezer compartment by the temperature sensor. If the temperature is lower than the set temperature, it can control the cooling according to the temperature difference until it reaches the shutdown temperature, and the heater will defrost. The temperature of each room of a household refrigerator is different, and during the heat preservation (maintenance) period of the refrigerator (most of the working time of the refrigerator belongs to the heat preservation time), the demand for cooling capacity of each room is certain, and the existing The refrigerato...
