Control method and system for refrigerator

Abstract

The invention provides a control method and system for a refrigerator. The control method includes the steps that a first time interval is preset, a controller (220) controls a compressor (230) to stop operating after continuing to operate for a period of time or stop operating after the controller starts the compressor to operate for a period of time; the control system comprises a processor (300), the processor (30) is used for judging the operation state of the compressor within the first time interval and controlling the operation of the compressor by combination with temperature detected by a temperature sensor (210); and the processor controls the compressor to stop operating through the controller after the compressor operates for a period of time or stop operating after the compressor is started and operates for a period of time. The control method and system for the refrigerator have the beneficial effects that a storage chamber (5) is further refrigerated by making the compressor to be started to operate for a period of time or to continue to operate for a period of time, so that the temperature in the storage chamber with the temperature reduced in advance does not rise too much even when the temperature of the storage chamber rises suddenly, and the preservation capacity of the storage chamber for food stored in the storage chamber is facilitated.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a control method and a control system for a refrigerator. Background technique [0002] In the prior art, the ability of the refrigerator to keep the food fresh is often not ideal, one of the reasons is that the temperature in the storage room of the refrigerator is easily affected by external factors and the temperature rises temporarily. For example, when the user opens the door of the storage room of the refrigerator to store food, the outside air with a higher temperature will flow into the storage room and cause the overall temperature of the storage room to rise, or the user puts relatively high-temperature food in the storage room. It will also cause the temperature in the storage room to rise, thereby affecting the freshness preservation ability of the storage room for the food stored therein to a certain extent.

[0002] In the prior art, the ability of the refrigerator to keep the food fresh is often not ideal. One of the reasons is that the temperature in the storage room of the refrigerator is easily affected by external factors and there is a temporary temperature rise.

For example, when the user opens the door of the storage room of the refrigerator to store food, the outside air with a higher temperature will flow into the storage room and cause the overall temperature of the storage room to rise, or the user puts relatively high-temperature food in the storage room. It will also cause the temperature in the storage room to rise, which will affect the freshness of the food stored in the storage room to a certain extent.
