Zoned cooling control method and zoned cooling control device for refrigerator freezer

Abstract

The invention provides a partition refrigeration control method and a partition refrigeration control device for a refrigerating chamber of a refrigerator. Wherein the refrigerating room of the refrigerator is divided into a plurality of storage spaces, and the refrigerating room is provided with an infrared sensor device, a branch air supply device and the like. The partition refrigeration control method includes: obtaining the temperature of stored items in multiple storage spaces sensed by an infrared sensor device; judging whether the temperature of the stored items meets the preset fast cooling start condition; if so, driving the cold source to quickly cool mode and open the refrigerating air door between the cold source and the branch air supply device, in which in the fast cooling mode, the refrigerating fan and compressor in the cold source run at a higher speed than the normal cooling mode; according to each storage The temperature of the stored items in the space determines the setting of its cooling state identification; the branch air supply device is driven to run to a state corresponding to the cooling state identification of multiple storage spaces. The solution of the invention can avoid the waste of electric energy and improve the storage effect of the refrigerator.

Description

technical field [0001] The invention relates to refrigerator control, in particular to a method for controlling zonal cooling and a device for controlling zonal cooling in a refrigerating room of a refrigerator. Background technique [0002] Existing refrigerators usually use a temperature sensor arranged inside the refrigerating chamber to sense the temperature around the location where it is arranged, and use the temperature as a basis for refrigeration control. [0003] However, when using this control method to control the refrigerator, when the temperature measured by the temperature sensor is higher than the preset value, the refrigerator compartment starts cooling. In the case that the refrigerator compartment is divided into multiple relatively independent storage spaces by shelf partitions, the temperature in the storage space where items have just been placed may be higher than other storage spaces. Using the existing refrigerator temperature control method, it is ...
