Fig. 3 is a schematic flow chart of a dehumidification control method for a refrigerator according to an embodiment of the present invention, where an execution main body of the embodiment may be the controller in the embodiment shown in fig. 1. As shown in fig. 3, the method includes:
s301: and responding to a dehumidification starting instruction, acquiring the temperature of the dehumidification module detected by the temperature detection module and acquiring the humidity of the chamber detected by the humidity detection module.
In the embodiment of the invention, a user can send a dehumidification starting instruction to a controller of the refrigerator by controlling the terminal application software of the refrigerator, and can also send the dehumidification starting instruction to the controller by pressing a key special for starting dehumidification.
Illustratively, in the dehumidification control method for the refrigerator provided by the invention, different dehumidification modes are provided for users, and the users can select different dehumidification functions according to the storage requirements of food materials. Specifically, the user may select the dehumidification mode in the terminal application software of the refrigerator, and the user may also select the dehumidification mode in the control key of the refrigerator. And after receiving the dehumidification starting instruction, the controller analyzes the dehumidification starting instruction and determines a dehumidification mode contained in the dehumidification starting instruction.
In the embodiment of the invention, after the dehumidification starting instruction is received, a control instruction for measuring the temperature is sent to a plurality of temperature sensors contained in the temperature detection module, and the temperature of the dehumidification module is measured by the temperature detection module. The controller also sends a control instruction for measuring the humidity of the chamber to the humidity detection module, namely the humidity sensor, and receives the chamber humidity detected by the humidity detection module. Specifically, the temperature sensor may be an infrared sensor.
S302: if the temperature of the dehumidification module is judged to be lower than the preset starting temperature, the heating module is controlled to heat the dehumidification assembly, or if the temperature of the dehumidification module is judged to be higher than or equal to the preset starting temperature, the dehumidification assembly is controlled to start dehumidifying the compartment.
Illustratively, the dehumidification module is an electrolytic dehumidifier, and specifically, an electrolytic dehumidification technology is adopted to realize that electrochemical reaction finishes the transfer of water molecules to achieve the dehumidification effect. Specifically, under the condition that voltage is applied to the electrolytic dehumidifier, the anode side connected with the positive electrode of the power supply generates the reaction of water and hydrogen ions through the decomposition of water molecules, the hydrogen ions pass through the electrolyte membrane to reach the cathode side, and the surface of the cathode is combined with oxygen in the air to generate water molecules, so that the water molecules are transferred from one side to the other side. The electrolytic dehumidifier has the advantages of long-term stable low-humidity state, low energy consumption and no noise.
In the embodiment of the invention, in order to ensure the environmental temperature of the electrolytic dehumidifier during the electrochemical reaction and avoid the influence on the rate of the electrochemical reaction due to too low temperature, the heating module can be used for heating the dehumidifying component so as to realize the function of controlling the temperature of the electrolytic dehumidifier. Specifically, when the temperature of the dehumidification module is judged to be lower than the preset starting temperature, the heating module is controlled to heat the dehumidification assembly.
For example, when it is determined that the temperature of the dehumidification assembly is lower than the preset maximum temperature, the heating module is controlled to heat the dehumidification assembly. Specifically, after the control dehumidification subassembly begins to dehumidify the room for a period of time, the condition that the temperature drops can appear in the dehumidification subassembly, and the temperature of dehumidification subassembly can be less than and predetermine the start-up temperature, consequently, can in time heat the dehumidification subassembly for the temperature of dehumidification subassembly keeps being greater than or equal to and predetermines the start-up temperature, be less than and predetermine the interval of highest temperature, in order to guarantee the dehumidification efficiency of dehumidification subassembly.
In the embodiment of the invention, if the temperature of the dehumidification module is confirmed to be greater than or equal to the preset starting temperature before the heating module is controlled to heat the dehumidification component, the dehumidification component can be directly controlled to start dehumidifying the compartment. Illustratively, the dehumidifying component comprises an electrolytic dehumidifier and a fan, and the dehumidifying function is realized by controlling the electrolytic dehumidifier to dehumidify the chamber and controlling the fan to blow air to the chamber.
Illustratively, the preset starting temperature is any temperature parameter between 8 degrees celsius and 10 degrees celsius.
S303: and if the temperature of the dehumidifying component is judged to be greater than or equal to the preset maximum temperature, controlling the heating module to stop heating.
In the embodiment of the invention, in order to ensure the indoor refrigeration effect of the refrigerator compartment, in the process of controlling dehumidification according to the temperature of the dehumidification component, the preset highest temperature corresponding to the dehumidification component can be set, namely when the temperature of the dehumidification component is judged to be greater than or equal to the preset highest temperature, the heating module is controlled to stop heating.
Illustratively, the preset maximum temperature is any temperature parameter between 10 degrees celsius and 14 degrees celsius.
S304: and if the humidity of the chamber is judged to be less than or equal to the preset humidity, controlling the dehumidifying component to stop dehumidifying the chamber.
In the embodiment of the invention, after the dehumidification of the compartment by the dehumidification component is controlled, when the humidity of the compartment is judged to be less than or equal to the preset humidity, the dehumidification component can be controlled to stop dehumidifying the compartment, so that electric energy waste caused by excessive dehumidification is avoided.
For example, after the dehumidification start command is analyzed and the dehumidification mode is determined in S301, the preset humidity corresponding to each dehumidification mode is pre-stored in the controller. Specifically, the preset humidity corresponding to the dehumidification mode can be determined, and when the humidity of the dehumidification assembly is judged to be smaller than or equal to the preset humidity, the dehumidification assembly is controlled to stop dehumidifying the compartment.
The refrigerator dehumidification control method provided by the embodiment realizes the function of dehumidifying the refrigerator by arranging the dehumidification component in the chamber of the refrigerator, and heats the dehumidification component by arranging the heating module, so that the temperature of the dehumidification component is in the optimal temperature interval of the electrolytic dehumidification chemical reaction, the electrolytic dehumidification efficiency of the dehumidification component is improved, and the dehumidification effect in the refrigerator is guaranteed.
Fig. 4 is a second flowchart illustrating a method for controlling dehumidification of a refrigerator according to an embodiment of the present invention. In the embodiment of the present invention, on the basis of the embodiment provided in fig. 3, the method for automatically controlling the temperature of the dehumidification assembly provided in the embodiment of the present invention specifically includes:
s401: and responding to a dehumidification starting instruction, acquiring the temperature of the dehumidification module detected by the temperature detection module and acquiring the humidity of the chamber detected by the humidity detection module.
S402: if the temperature of the dehumidification module is judged to be lower than the preset starting temperature, the heating module is controlled to heat the dehumidification assembly, or if the temperature of the dehumidification module is judged to be higher than or equal to the preset starting temperature, the dehumidification assembly is controlled to start dehumidifying the compartment.
S403: and if the temperature of the dehumidifying component is judged to be greater than or equal to the preset maximum temperature, controlling the heating module to stop heating.
S404: and if the humidity of the compartment is judged to be less than or equal to the preset humidity, controlling the dehumidifying component to stop dehumidifying the compartment.

S405: and generating a dehumidification finishing instruction, and turning on a dehumidification finishing indicator lamp according to the dehumidification finishing instruction.
In the embodiment of the invention, the indication lamp is arranged on the dehumidification function control panel of the refrigerator, and the indication lamp is turned on when the dehumidification function is finished so as to prompt a user that the dehumidification is finished.
For example, when it is determined that the humidity of the chamber is less than or equal to the preset humidity, dehumidification completion information may be generated and sent to the user terminal to prompt the user that dehumidification is completed.
S406: and acquiring the compartment humidity detected by the humidity detection module.
For example, the compartment humidity detected by at least one humidity sensor is obtained and the average of all the compartment humidities detected is determined as the compartment humidity. In the embodiment of the invention, the number of the humidity sensors can be multiple, namely, the humidity sensors for collecting the humidity of the compartment are uniformly arranged in the compartment, and the average value of the humidity measured by all the humidity sensors is determined as the humidity of the compartment, so that the problem of inaccurate humidity measurement caused by unfixed food placing positions of users is avoided.
