Partition refrigeration control method and device for refrigerating chamber of refrigerator

Abstract

The invention provides a partition refrigeration control method and device for a refrigerating chamber of a refrigerator. The refrigerating chamber of the refrigerator is divided into multiple storage spaces. Infrared sensing devices, branch air supply devices and the like are arranged in the refrigerating chamber. The partition refrigeration control method includes the steps that the temperatures, sensed by the infrared sensing devices, of stored objects in the storage spaces are acquired; whether the temperatures of the stored objects meet the preset quick refrigeration start condition or not is judged; if yes, a cold source is driven to run in a quick refrigeration mode, refrigeration air doors between the cold source and the branch air supply devices are opened, and in the quick refrigeration mode, a refrigeration draught fan and a compressor in the cold source run at the rotating speed higher than that in a normal refrigeration mode; refrigeration state mark arrangement of the stored objects is determined according to the temperatures of the stored objects in the storage spaces. The branch air supply devices are driven to run in the states corresponding to refrigeration state marks of the storage spaces. By the adoption of the scheme, electric energy waste can be avoided, and the storage effect of the refrigerating chamber is improved.

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 ...

During this process, the temperature of the item may be transmitted to other items in contact with it, resulting in a change in the temperature of the food already stored in the refrigerator, resulting in loss of nutrition and reduced storage effect
