Refrigerator and controlling method for ice-making air returning

Abstract

The invention relates to the technical field of refrigerating equipment, in particular to a refrigerator and a controlling method for ice-making air returning. The refrigerator comprises an ice-making chamber, low-temperature storage chambers, a first evaporation compartment providing refrigerating capacities for the ice-making chamber and a second evaporation compartment providing refrigerating capacities for the low-temperature storage chambers. An air outlet of the first evaporation compartment communicates with an air inlet of the ice-making chamber. The ice-making chamber comprises a first air outlet and second air outlets. The first air outlet of the ice-making chamber communicates with an air returning opening of the first evaporation compartment. The second air outlets of the ice-making chamber communicate with the low-temperature storage chambers. A first air door and second air doors are arranged at the first air outlet and the second air outlets correspondingly. The first evaporation compartment and the low-temperature storage chambers communicate through air returning channels, and third air doors are arranged on the air returning channels between the first evaporation compartment and the low-temperature storage chambers. Different ice-making air returning modes are adopted under different patterns, and the redundant refrigerating capacities can be provide for the low-temperature storage chambers for refrigerating while fast ice-making is guaranteed, so that the energy utilization rate of the refrigerator is increased.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator and a method for controlling ice-making return air. Background technique [0002] With the development of social life, the functions of refrigeration equipment are also increasing. There are existing refrigeration equipment with automatic ice-making function on the door body. , When the ice-making room needs cooling capacity, the cold air needs to be transported to the ice-making room through the fan and the air duct. The air duct has a long stroke, which generates relatively large resistance along the way and relatively large energy loss. [0003] Since the cooling capacity of the ice making system is provided by the refrigerating room or the evaporator of the freezing room, the cooling capacity provided is relatively small, resulting in a relatively low ice making capacity and ice making speed of the ice making system, which cannot meet the user's...
