Adding an independent water source will occupy the volume of the refrigerator, and the fresh air introduced by the water-free fresh air humidity control technology cannot be adjusted.

[0088] With the above arrangement, when fresh air is introduced into the target space, conditioned air is mixed in, and the air volume of the conditioned air is adjusted according to the temperature and humidity in the target space, thereby adjusting the temperature and humidity of the fresh air, so that the humidity and temperature of the air entering the target space are appropriate, thereby ensuring the freshness requirement in the target space, and being able to effectively solve the technical problem that the fresh air introduced into the refrigerator carries a large amount of moisture and heat; at the same time, by reducing the condensation amount in the fruit and vegetable compartment, the working frequency of the electric heating wire is indirectly reduced, thereby preventing the temperature of the fruit and vegetable compartment from rising due to the operation of the electric heating wire, causing the loss of cold energy, and achieving the purpose of energy saving of the refrigerator.

[0096] By adopting the above setting, it is determined whether the temperature in the target space is normal. If it is normal, there is no need to introduce fresh air, thus reducing energy consumption.

[0097] The air inlet structure of this embodiment is described as follows:

[0098] Embodiment 1:

[0099] The overall structure of the air intake structure of this embodiment is composed of the compartment component 3, the humidity control membrane 5, the temperature and humidity sensor 4, the oxygen control membrane 6, the air intake assembly 1, the dehumidification damper 31 and other components. The air intake assembly 1 mainly serves to introduce the external fresh air through the air intake duct, and after the activated carbon in the activated carbon box 14 adsorbs and removes impurities, it is introduced into the compartment component 3 to increase the internal humidity of the compartment component 3. The temperature and humidity sensor 4 detects whether the internal humidity of the compartment component 3 reaches the preset value range, and controls the start of the fan component 13 and the operation state of the dehumidification damper 31 through the electronic control main board according to the temperature and humidity of the compartment. The dehumidification damper 31 adjusts the internal humidity of the compartment component 3 through the opening and closing state of the damper. When the internal humidity of the compartment component 3 is too high, the damper is opened, and the humid air inside the compartment is discharged to the outside of the compartment through air convection to prevent the internal humidity from being too high to form condensed water. The humidity control membrane 5 and the oxygen control membrane 6 assist in adjusting the internal humidity and oxygen concentration of the compartment component 3.

[0100] Embodiment 2:

[0101] The air inlet assembly 1 of the air inlet structure of this embodiment is composed of an activated carbon box 14, a fan component 13, an air inlet duct, a heating wire (i.e., a heating component 17), a windshield 22, a motor cover, a gear cover, a ventilation cover, an air inlet duct, a gear, a driving motor 23 and other parts. The air inlet duct is pre-buried in the foaming layer between the box 7 and the back plate, the ventilation cover is installed on the back plate of the refrigerator, and the air inlet duct is connected to the compartment component 3. Under the assembly of the air inlet duct, the air inlet duct and the ventilation cover, a ventilation duct is formed that runs through the foaming layer of the refrigerator and connects the refrigerator moisturizing compartment component 3 with the outside world. The fan component 13 is installed in the air inlet duct, and the outside fresh air is quickly introduced into the compartment component 3 through the driving motor 23. The activated carbon box 14 is installed at the port of the air inlet duct. The micropores on the activated carbon box 14 can change the air volume and wind speed to achieve windless air supply. A windshield 22, gears and a drive motor 23 are installed on the top of the air inlet duct. The gear cover and the motor cover are used to fix the gears and the motor. The windshield 22 is opened or closed by the drive motor 23, thereby achieving the purpose of autonomously controlling the cold air inside the refrigerator body to enter the fresh air system channel.

[0102] Embodiment three:

[0103] In the control method of this embodiment, the user adjusts the humidity range of the compartment according to the type of fruits and vegetables stored in the compartment. The temperature and humidity sensor detects whether the humidity of the compartment meets the preset value. If the humidity of the compartment is greater than the preset value, the fan does not start, and the dehumidification damper 31 on one side of the moisturizing compartment is opened to bring the moisture out of the compartment through air convection. At the same time, the wind shield is fully opened, and dry cold air also enters the compartment through air convection. After the humidity of the compartment reaches the preset value, the damper and the wind shield are closed; if the humidity of the compartment is less than the preset value, the dehumidification damper is closed, and the fan component 13 is started to introduce fresh air from the outside to humidify the compartment component 3. The operation process of the fan component 13 When the medium temperature and humidity sensor 4 detects that the temperature and humidity in the compartment are rising too fast, the main board controls the driving motor 23 to rotate, opens the wind shield 22, and rotates the fan component 13 to introduce the cold air in the refrigerated compartment into the fresh air system channel, and mixes the low-temperature and dry cold air with the high-humidity and high-temperature fresh air in the fresh air system to reduce the moisture and heat in the fresh air, so as to avoid the fresh air entering the fruit and vegetable compartment component 3 from forming a large amount of condensation inside the moisturizing compartment component 3 due to excessive humidity and temperature, causing the food to rot due to soaking in water, and too much condensed water will cause the compartment electric heating wire to work frequently, affecting the compartment temperature and causing unnecessary cooling loss.

[0104] The windshield 22 can be controlled to open at different angles by driving the driving motor 23. This program sets the windshield 22 to have three opening angles, namely 30 degrees, 60 degrees and fully opened 90 degrees. The opening angle of the windshield 22 is related to the temperature and humidity in the fresh air. When the temperature and humidity sensor 4 detects that the temperature and humidity in the compartment rise sharply in a short period of time, the windshield 22 opens to 90 degrees, and the fan component 13 introduces the maximum cold air and the fresh air for premixing; when the temperature and humidity in the compartment rise rapidly in a short period of time, the windshield 22 opens 60 degrees, and the fan component 13 introduces two-thirds of the cold air and the fresh air for premixing; when the temperature and humidity in the compartment rise slowly in a short period of time, the windshield 22 opens 30 degrees, and the fan component 13 introduces one-third of the cold air and the fresh air for premixing.

[0105] In summary, the application of this method can effectively solve the problem of a large amount of condensation generated in the fruit and vegetable compartment during the fresh air humidity control process of the existing refrigerator without a water source, which affects the preservation of food ingredients; at the same time, by reducing the amount of condensation in the fruit and vegetable compartment, the working frequency of the electric heating wire is indirectly reduced, preventing the temperature of the fruit and vegetable compartment from rising due to the operation of the electric heating wire, causing the loss of cold energy, and achieving the purpose of energy saving of the refrigerator.
