Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0025]The embodiment of the present invention provides a method for controlling the humidity in the refrigerator. The method is also applicable to the humidity control in the wine cabinet. The method requires that the refrigerator or the wine cabinet use a frequency conversion compressor system. When the compressor runs at high frequency, the evaporating temperature is relatively low, and there will be more condensed water in the cabinet, and the relative humidity in the cabinet will drop rapidly. There is relatively little dew, and the relative humidity in the cabinet drops slowly. According to this principle, when the humidity in the cabinet is high, the operating frequency of the compressor can be increased to reduce the relative humidity in the cabinet. Similarly, when the humidity...

Abstract

The invention discloses a method and device for controlling the humidity in a refrigeration cabinet. The method comprises the steps of controlling a compressor of the refrigeration cabinet to operate at the refrigeration frequency according to the temperature in the refrigeration cabinet and the set temperature, and starting the refrigeration mode; under the refrigeration mode, if it is judged that the humidity in the cabinet is lower than the first preset value, reducing the operation frequency of the compressor within the operation frequency range of the compressor, and starting the frequency-decreasing humidity control mode so as to improve the humidity in the cabinet; and before the compressor enters the frequency-reducing humidity control mode, if it is judged that the humidity in the cabinet is higher than the second preset value, improving the operation frequency of the compressor within the operation frequency range of the compressor, and starting the frequency-increasing dehumidification mode so as to reduce the humidity in the cabinet. By controlling the frequency operation range of the inverter compressor, high-frequency dehumidification and low-frequency humidity control are achieved, the effect that relative humidity in the refrigeration cabinet fluctuates within a certain range is ensured, control over humidity is accurate, and no component needs to be additionally arranged.

Description

technical field [0001] The present invention relates to the technical field of humidity control of refrigerators, in particular to a method and device for controlling the humidity inside the refrigerator. Background technique [0002] Due to the low evaporation temperature of the existing refrigerators, the air in the cabinets condenses, resulting in low humidity in the cabinets. Usually, the following methods are used to increase the humidity in the cabinets: [0003] (1) add a humidifier; or [0004] (2) Design the condensation water tank and add fans or heaters to evaporate the water in the water tank to increase the humidity in the cabinet. [0005] However, the above-mentioned method needs to add additional devices, takes up space, and the humidity control is inaccurate. Contents of the invention [0006] Embodiments of the present invention provide a method and device for controlling the humidity inside a refrigerator to solve the problems in the prior art that the...
