Refrigerator control method and device

Abstract

The invention provides a control method and device of a refrigerator. The control method of the refrigerator comprises the following steps: detecting a current humidity value at a smell sensor; acquiring a previous humidity value at the smell sensor, the smell sensor being integrally provided with a humidity sensor configured to periodically acquire the humidity value at the smell sensor; calculating the difference value between the current humidity value and the previous humidity value; judging whether the difference value is greater than or equal to a preset difference value threshold; and if yes, determining that the dehumidification structure reaches the saturation state, and the refrigerator is controlled to enter the reduction mode. According to the scheme, after it is determined that the dehumidification structure reaches the saturation state, the refrigerator is controlled to enter the reduction mode, the dehumidification structure is reduced, the situation that the dehumidification effect is affected when the dehumidification structure absorbs water to be saturated is avoided, the dehumidification capacity of the dehumidification structure is guaranteed, and therefore it can be guaranteed that the humidity in the air return duct is low.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a method and device for controlling a refrigerator. Background technique [0002] With the development of society and the continuous improvement of people's living standards, people's pace of life is getting faster and faster, so they are more and more willing to buy a lot of food and put it in the refrigerator. The refrigerator has become one of the indispensable household appliances in people's daily life. . [0003] However, after storing a large amount of food in the refrigerator, the following problems often occur: the user may forget that some food is stored in the refrigerator, resulting in food expiration and waste; affect health. In the current prior art, an odor sensor is provided in the refrigerator, so as to determine the freshness of food by detecting the odor value in the storage compartment. However, the humid environment in the refrigerator storage...
