Refrigerator control method, refrigerator control system and refrigerator

Abstract

The invention provides a refrigerator control method, a refrigerator control system and a refrigerator. The refrigerator control method comprises the following steps: judging whether a refrigerating chamber has a refrigerating request or not; detecting whether a fan is started up or not if the refrigerating chamber does not have the refrigerating request; and opening a refrigerating air door when the fan is not started up to allow air in a freezing chamber to enter the lower part of the refrigerating chamber through a refrigerating air return channel and to allow air at the upper part of the refrigerating chamber to enter the freezing chamber through a refrigerating air inlet channel. According to the refrigerator control method, natural convection is formed due to a relatively great temperature difference between the freezing chamber and the refrigerating chamber by opening the refrigerating air door, cold air enters the refrigerating chamber from the freezing chamber along the refrigerating air return channel, is deposited downwards, and performs complementary cooling on the space at the lower part of the refrigerating chamber, so that the lower part of the refrigerating chamber with higher temperature is fully cooled down, the temperature is reduced, the temperature difference of the whole refrigerating chamber is reduced, and the preservation effect of the whole refrigerating chamber is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerator control method, a refrigerator control system and a refrigerator. Background technique [0002] Nowadays, large-capacity refrigerators usually adopt a single-system side-by-side door structure. The heat load of the refrigerator is relatively large at room temperature (such as 25°C) or above. The air outlet is also in the upper part, and the cold air is conveyed from the top to the bottom, and the height of the refrigerator room with the door open is relatively high, so the temperature distribution in the refrigerator room is often uneven, the upper part is colder, and the lower part is hotter. During the refrigerating cycle of the refrigerator, the temperature distribution in the refrigerating chamber gradually changes from cold to hot from top to bottom; in addition, due to structural limitations, the lower part of the refrigerating It is also difficult for...

AI Technical Summary

Problems solved by technology

The lower space of the refrigerating room will become the place with the highest temperature in the whole refrigerating room. The uneven temperature in the refrigerating room and its various compartments is not conducive to precise temperature control, and the higher temperature in the lower part will make the fresh-keeping effect of the lower part worse.
