Refrigerator temperature control method and device as well as refrigerator

Abstract

The invention relates to a refrigerator temperature control method and device as well as a refrigerator, and belongs to the technical field of refrigerator temperature control. The refrigerator temperature control method comprises the following steps: obtaining a room temperature of each room of the refrigerator; determining whether or not the refrigerator needs to enter relay refrigerating control according to the room temperature, controlling the refrigerator to perform delay refrigerating control if delay refrigerating control is needed, and stopping refrigerator refrigerating after delay refrigerating control is ended. The refrigerating temperature control method facilitates guaranteeing refrigerating freshness-keeping temperature-control effect during a shut-down protection period, ofthe refrigerator.

Description

technical field [0001] The application belongs to the technical field of refrigerator temperature control, and in particular relates to a refrigerator temperature control method, a device and a refrigerator. Background technique [0002] With the advancement of modern technology, frequency conversion electronically controlled refrigerators are becoming more and more popular, and people's demand for freshness in refrigerators is increasing day by day. Precise temperature control has high requirements on the temperature accuracy of the sensor and the control of the working state of the electrical components by the main control board. Take the air-cooled refrigerator as an example. When the compressor of the traditional air-cooled refrigerator is shut down, the system pressure will not be balanced in a short period of time. Immediately starting the compressor will cause damage, or even burn the compressor, so the general control rules will have a period of time (for example: te...

Problems solved by technology

Precise temperature control has high requirements on the temperature accuracy of the sensor and the control of the working state of the electrical components by the main control board. Take the air-cooled refrigerator as an example. When the compressor of the traditional air-cooled refrigerator is shut down, the system pressure will not be balanced in a short period of time. Immediately starting the compressor will cause damage, or even burn the compressor, so the general control rules will have a period of time (for example: ten minutes) shutdown protection time

see figure 1 , figure 1 is a schematic diagram showing the change of compartment temperature during shutdown protection according to an exemplary embodiment, as shown in figure 1 As shown, when the refrigerator is running, because the cooling rate and heating rate of each compartment are different, it is impossible to guarantee that the temperature of each compartment reaches the start-stop point synchronously

During the compressor shutdown protection period, if the temperature of any room reaches the starting point, but the compressor cannot be started due to the startup protection, the temperature of each room will continue to rise, such as figure 1 It shows that the temperature of the refrigerated compartment exceeds the start-up point during the compressor shutdown protection period, which will result in a decline in the freshness preservation effect of the refrigerated compartment
