Embodiment 1

[0056] The cooling of the refrigerated compartment of the air-cooled refrigerator is usually achieved by the cooling fan passing the cold air to the refrigerated compartment through the air duct. The temperature in the lower half is high. During the non-refrigerating period, the temperature in the upper half is high and the temperature in the lower half is low. This uneven temperature in the refrigerated compartment often leads to frosting in the refrigerated compartment in the lower half, and it will As a result, the temperature collected by the temperature sensor in the refrigerated room, which can only detect the temperature of the air near itself, is inaccurate, resulting in the frequent start and stop of the compressor used for refrigeration, which increases the power consumption of the refrigerator and reduces the reliability of the compressor. In addition, low-temperature cold air blowing directly into the refrigerated compartment will cause food frostbite and freeze, wh...

Embodiment 2

[0083] For ease of understanding, an example of a refrigerator control method is provided below for illustration. In practical applications, the temperature field in the refrigerated compartment will be disturbed for a certain period of time before detecting the temperature of the refrigerated compartment to obtain an accurate refrigerated compartment temperature. temperature, and compare the difference between the temperature of the refrigerating room and the set refrigerating temperature with the temperature threshold of the stop point, and then compare it with the temperature threshold of the start point, fully considering the temperature value of the start and stop points of the refrigeration, and clarifying the location of the refrigerating room to determine whether there is a cooling demand for the refrigerated compartment.

Abstract

The present application relates to a refrigerator control method. The method includes: obtaining the power-on time of the refrigerating unit, and when the power-on time is longer than the preset power-on time, controlling the refrigerating fan to turn on, and the refrigerating fan is used to disturb the temperature field of the refrigerating room; Material temperature: compare the first temperature difference with the temperature threshold of the start-up point of the refrigeration unit, the first temperature difference is the difference between the temperature of the refrigerated compartment and the set refrigeration temperature, and the temperature threshold of the start-up point is greater than zero; when the first temperature difference is greater than the temperature threshold of the start-up point , compare the second temperature difference with the cold storage temperature difference threshold, the second temperature difference is the difference between the temperature of the cold storage material and the set refrigeration temperature, and the cold storage temperature difference threshold is less than zero; when the second temperature difference is greater than the cold storage temperature difference threshold, the refrigeration unit is controlled to start. The solution provided by the present application can optimize the cooling start-up rate of the refrigerated compartment, improve the energy efficiency of the refrigerator, and improve the freshness preservation effect of the refrigerated compartment.
