When the ambient temperature and humidity are high and reach the dew point temperature, due to the large temperature difference between the internal compartment of the refrigerator and the external ambient temperature and the poor insulation effect of the refrigerator door, the water vapor in the air will condense on the surface of the refrigerator door to form water droplets and water mist. This phenomenon is particularly prominent on the surface of the freezer door.

[0039] Condensation on the refrigerator door is a common problem, mainly caused by the temperature difference between the inside and outside of the refrigerator. When the temperature inside the refrigerator is low, and the ambient temperature and humidity are high and reach the dew point temperature, due to the large temperature difference between the internal compartment of the refrigerator and the external ambient temperature, and the poor insulation effect of the refrigerator door, the surface of the refrigerator door will become colder than the surrounding air, so that the moisture in the hot and humid air that contacts the surface of the refrigerator door condenses into small water droplets, and the water vapor in the air condenses on the surface of the refrigerator door to form water droplets and mist, etc. This phenomenon is particularly prominent on the surface of the freezer door. At the same time, refrigerators are generally placed in the kitchen, where the temperature and humidity are high, and condensation is easy to occur.

[0040] In order to solve the problem of condensation on the refrigerator door, the refrigerator door is generally thickened, or a VIP board (Vacuum Insulation Panel) is pasted inside the door to improve the insulation effect of the refrigerator door and prevent the temperature difference between the refrigerator surface and the ambient temperature from being too large. However, the thickening of the refrigerator door and the use of the VIP board will increase the cost. Although the VIP board can greatly improve the thermal insulation performance, since the refrigerator door is usually opened and closed frequently, the moisture in the environment still has the opportunity to enter and contact the colder door surface, thus forming condensation. In addition, the refrigerator door frame, sealing strip and other parts may also condense due to poor sealing, so it is impossible to completely prevent the occurrence of condensation on the door surface.

[0041] In order to more effectively reduce the condensation problem on the surface of a refrigerator door, a refrigerator is provided in this embodiment, which includes a door body and a controller; an air-conditioning system, a temperature sensor, and a humidity sensor are arranged on the door body; the temperature sensor is used to detect the ambient temperature of the door body; the humidity sensor is used to detect the ambient humidity of the door body; the controller is connected to the temperature sensor and the humidity sensor respectively; the controller is used to determine the ambient dew point temperature according to the detected ambient temperature, and when the ambient dew point temperature reaches a preset dew point temperature threshold and the detected ambient humidity reaches a preset first humidity threshold, the air-conditioning system is turned on to dehumidify the door body; air-conditioning vents and dehumidification air duct inlets are arranged at the front edges on both sides of the refrigerator door body.

[0042] refer to Figure 1 , Figure 11 is a schematic diagram of a refrigerator door structure provided by an embodiment of the present application. An air conditioning system 20, a temperature sensor 30 and a humidity sensor 40 are arranged on the door 10 of the refrigerator 100. The temperature and humidity of the door 10 environment are detected in combination with the temperature sensor 30 and the humidity sensor 40. Based on the detected temperature and humidity, the air conditioning system 20 is controlled to be turned on by the controller according to the preset control logic, thereby performing a dehumidification operation on the door 10 of the refrigerator 100. Specifically, the controller can simultaneously control the refrigerator 100 and the air conditioning system 20, and based on the real-time temperature and humidity of the door 10 of the refrigerator 100, the air conditioning system 20 is controlled to perform a dehumidification operation on the door 10 of the refrigerator 100.

[0043] The positions and quantities of the air conditioning system 20, the temperature sensor 30, and the humidity sensor 40 are determined according to the specific assembly requirements of the refrigerator 100. Figure 1 The positions and quantities shown are for reference only.

[0044] Furthermore, an embodiment of the present application also provides an air outlet structure of a refrigerator door; Figure 2 This is a schematic diagram of the air outlet structure of a refrigerator door provided in an embodiment of the present application;

[0045] refer to Figure 2 The front edges of both sides of the door of the refrigerator are provided with dehumidification air duct air inlets, including a first dehumidification air duct air inlet 14 and a second dehumidification air duct air inlet 15. When the environmental conditions around the refrigerator are monitored in real time by the temperature and humidity sensor, and the current dew point temperature is calculated according to the ambient temperature and relative humidity, the dew point temperature and ambient humidity are judged. If the dew point temperature and ambient humidity reach the threshold value, the controller controls the opening of the dehumidification air duct air inlet, and the dry air is sent to the air inlets at the front edges of both sides of the refrigerator door through the dehumidification air duct air inlet to reduce or prevent condensation.

[0046] In one possible embodiment, a small and efficient air inlet fan is provided in the dehumidification air duct structure of the refrigerator to assist the flow of dry air.

[0047] Further, refer to Figure 2 Air conditioning vents are arranged at the front edges of both sides of the door body of the refrigerator, wherein the air conditioning vents include an air conditioning refrigeration duct air inlet 18 and an air conditioning refrigeration duct air outlet, the air conditioning refrigeration duct air inlet 18 is used to inhale the ambient air of the environment in which the refrigerator is located; the air conditioning refrigeration air outlet is used to deliver cold air to the environment in which the refrigerator is located, specifically, including a first air conditioning refrigeration duct air outlet 16 and a second air conditioning refrigeration duct air outlet 17, thereby cooling the environment in which the refrigerator is located, thereby reducing the difference between the internal temperature of the refrigerator and the ambient temperature of the refrigerator, which is beneficial to further reduce the generation of condensation on the refrigerator door.

[0048] In some of the embodiments, the refrigerator also includes a cabinet; a refrigerator refrigeration system is arranged in the cabinet; the refrigerator refrigeration system includes a refrigerant circulation pipeline, and a compressor, a condenser, an evaporator and a first solenoid valve 11 located in the refrigerant circulation pipeline; the first solenoid valve 11 is arranged on the refrigerant circulation pipeline between the condenser and the evaporator, and the air-conditioning system also includes an air-conditioning evaporator; the air-conditioning evaporator is connected to the refrigerant circulation pipeline through the first solenoid valve 11.

[0049] in, Figure 3 Schematic diagram of the structure of the circulating refrigeration system provided in the embodiment of the present application. Figure 3 The circulating refrigeration system is arranged in the refrigerator and at the refrigerator door, and the circulating refrigeration system includes a refrigerator refrigeration system and an air conditioning evaporator 13. The air conditioning evaporator 13 is arranged in the air conditioning system, and the refrigerator refrigeration system is arranged in the refrigerator box. At the same time, the air conditioning evaporator 13 in the air conditioning system is connected to the refrigerant circulation pipeline via the first solenoid valve 11 and the third capillary tube 12, so that the refrigerator refrigeration system and the air conditioning system share the same set of refrigerant circulation paths, but time-sharing control is achieved through the first solenoid valve 11. When the environmental conditions reach the preset threshold, the control system automatically switches the state of the first solenoid valve 11, starts the air conditioning system, and dehumidifies and cools the refrigerator door through the cold air generated by the air conditioning evaporator 13.

[0050] The compressor 1 on the refrigerant flow pipeline in the refrigerator refrigeration system is used to compress the refrigerant, increase its pressure and temperature, and flow out high-temperature and high-pressure refrigerant to the condenser 2. The condenser 2 cools the high-temperature and high-pressure gaseous refrigerant into liquid refrigerant and releases heat to the external environment. Thereafter, the liquid refrigerant passes through the evaporator to evaporate in a low-pressure environment, absorbing heat from the refrigerator body, thereby lowering the internal temperature of the refrigerator.

[0051] In some embodiments, the refrigerator refrigeration system further includes an auxiliary condenser 4 and a second solenoid valve 6; the input end of the auxiliary condenser 4 is connected to the output end of the anti-condensation pipe 3; the output end of the auxiliary condenser 4 is connected to the evaporator through the second solenoid valve 6.

[0052] Among them, by arranging the auxiliary condenser 4 on the refrigerant circulation pipeline, it is beneficial to further reduce the refrigerant temperature to ensure that the refrigerant in the refrigerant circulation pipeline is completely condensed into a liquid state.

[0053] When the refrigerator needs to be refrigerated, the first solenoid valve 11 is controlled to close the passage to the air conditioner evaporator 13, and the second solenoid valve 6 is controlled to open so that the refrigerant flows through the evaporator in the refrigerator to reduce the temperature inside the box. When the environmental conditions reach the preset dew point temperature and humidity threshold, the first solenoid valve 11 is controlled to open the passage to the air conditioner evaporator 13, and the second solenoid valve 6 is controlled to close to close the passage of the refrigerant to the refrigerator evaporator. The refrigerant passes through the air conditioner evaporator 13 to generate cold air and is sent to the air inlets on the front sides of the refrigerator door through the air duct for dehumidification and cooling.

[0054] In some embodiments, the refrigerator refrigeration system further includes an anti-condensation pipe 3; the anti-condensation pipe 3 is connected to the refrigerant flow pipeline between the condenser 2 and the evaporator; the output end of the anti-condensation pipe 3 is connected to the first solenoid valve 11. By providing the auxiliary condenser 4, the heat of the refrigerant in the condenser 2 can be dispersed, so that the heat load borne by each condenser 2 is reduced, thereby improving the heat dissipation efficiency, avoiding overload of a single condenser 2, and helping to extend the service life of the condenser 2.

[0055] Furthermore, when a failure occurs in the condenser 2, the auxiliary condenser 4 is controlled to continue to operate, thereby ensuring the continuous operation of the circulating refrigeration system.

[0056] Specifically, the anti-dew pipe 3 is connected to the high-temperature refrigerant circulation pipe discharged from the compressor 1, and uses the heat of this part of the refrigerant circulation pipe to heat the outer shell of the refrigerator, especially the water droplets condensed around the door seal of the refrigerator door, so as to achieve the effect of dehumidification and anti-dew.

[0057] In some of the embodiments, the refrigerator refrigeration system further includes a drying filter 5; the drying filter 5 is arranged on the refrigerant flow pipeline between the auxiliary condenser 4 and the evaporator.

[0058] In the refrigerant circulation pipeline, a filter drier 5 is arranged after the condenser 2, and the moisture and impurities in the refrigerant are removed by the filter drier 5, so as to protect the performance of each component in the refrigerant circulation pipeline from being damaged, thereby ensuring the efficient operation of the circulating refrigeration system. The filter drier 5 is usually equipped with a desiccant, such as a molecular sieve or activated carbon, which effectively absorbs the moisture in the refrigerant to prevent the moisture from forming ice blockage in the system or reacting with the lubricating oil to generate acidic substances, thereby protecting the compressor 1 and other key components.

[0059] In some embodiments, the evaporator includes a refrigerating evaporator 9; the refrigerator refrigeration system also includes a first capillary tube 7; the refrigerating evaporator 9 is connected to the condenser 2 through the first capillary tube 7. The evaporator also includes a freezing evaporator 10; the refrigerator refrigeration system also includes a second capillary tube 8; the freezing evaporator 10 is connected to the condenser 2 through the second capillary tube 8. The freezing evaporator 10 is connected to the compressor 1 through the refrigerating evaporator 9.

[0060] The circulating refrigeration system is provided with a refrigerating evaporator 9 and a freezing evaporator 10, wherein the refrigerating evaporator 9 is mainly responsible for cooling the refrigerating chamber, and the freezing evaporator 10 is responsible for cooling the freezing chamber, and the first capillary tube 7 and the second capillary tube 8 are used as throttling devices to respectively adjust the refrigerant flow entering the refrigerating evaporator 9 and the freezing evaporator 10. In the refrigerating evaporator 9, the refrigerant absorbs the heat in the refrigerating chamber and evaporates into a gaseous state; in the freezing evaporator 10, the refrigerant absorbs the heat in the freezing chamber and evaporates into a gaseous state.

[0061] The liquid refrigerant cooled by the condenser 2 will enter the refrigeration evaporator 9 after being decompressed by the first capillary tube 7, absorb heat and evaporate into gas in the refrigeration evaporator 9. The liquid refrigerant will enter the freezing evaporator 10 after being decompressed by the second capillary tube 8, and further absorb heat and evaporate in the freezing evaporator 10.

[0062] The freezing evaporator 10 is then connected to the compressor 1 through the refrigerating evaporator 9. At this time, the gaseous refrigerant in the freezing evaporator 10 is first collected in the refrigerating evaporator 9, and then returns to the compressor 1, thereby optimizing the flow path of the refrigerant and ensuring the overall refrigeration efficiency of the circulating refrigeration system.

[0063] In some of the embodiments, based on Figure 3 The circulating refrigeration system shown can realize various working states by respectively controlling the opening and closing of the first solenoid valve 11 and the second solenoid valve 6. Here, the first solenoid valve 11 is a one-way valve and the second solenoid valve 6 is a three-way solenoid valve.

[0064] Working state 1: the first solenoid valve 11 is closed and the second solenoid valve 6 is opened, and the refrigerant only flows through the air-conditioning evaporator 13, that is, at this time, in the three-circulation refrigeration system, only the air-conditioning system is working to cool the environment where the refrigerator is located.

[0065] Working state two: the first solenoid valve 11 is open, the second solenoid valve 6 is closed, and the second solenoid valve 6 is tangential to the end of the first capillary tube 7, then the refrigerant flows through the refrigeration evaporator 9 and the freezing evaporator 10, that is, at this time, only the refrigerator system is working in the three-circulation refrigeration system, and the refrigeration compartment and the freezing compartment are refrigerated at the same time.

[0066] Working state three: the first solenoid valve 11 is open, the second solenoid valve 6 is closed, and the second solenoid valve 6 is tangential to the end of the second capillary tube 8, then the refrigerant only flows through the freezing evaporator 10, that is, at this time, only the refrigerator system is working in the three-cycle refrigeration system, and only the freezing compartment is refrigerating.

[0067] Working state four: the first solenoid valve 11 and the second solenoid valve 6 are opened at the same time, and the second solenoid valve 6 is tangential to the end of the first capillary tube 7, then the refrigerant flows through the refrigeration evaporator 9, the freezing evaporator 10 and the air conditioning evaporator 13 at the same time, that is, at this time, the three-circulation refrigeration system is running at full power, the air conditioning system and the refrigerator system are working at the same time, and the refrigeration compartment, the freezing compartment and the environment in which the refrigerator is located are cooled at the same time.

[0068] Working state five: the first solenoid valve 11 and the second solenoid valve 6 are opened at the same time, and the second solenoid valve 6 is tangential to the end of the second capillary tube 8, then the refrigerant flows through the freezing evaporator 10 and the air conditioning evaporator 13 at the same time, that is, at this time, the air conditioning system and the refrigerator system in the three-circulation refrigeration system are working at the same time, and the freezing compartment and the room are cooled at the same time.

[0069] Working state six: the first solenoid valve 11 and the second solenoid valve 6 are closed at the same time, which means that the refrigerating compartment, the freezing compartment and the room have reached the shutdown point temperature and no further cooling is required.

[0070] By switching the opening and closing states of the first solenoid valve 11 and the second solenoid valve 6, as well as the tangent direction of the second solenoid valve 6, the interior of the refrigerator and the environment in which the refrigerator is located are cooled, so that the temperature difference between the inside and outside of the refrigerator is reduced, further reducing condensation on the refrigerator door.

[0071] Furthermore, since refrigerators at different time points and in different locations may have different ambient temperatures and ambient humidity conditions, the temperature sensor and humidity sensor need to work together to comprehensively control and determine the start and stop of the air-conditioning system, thereby preventing condensation on the door surface.

[0072] Therefore, a refrigerator dehumidification method is also provided in an embodiment of the present application, which is applied to the refrigerator in the above embodiment. Figure 4 It is a flow chart of a refrigerator dehumidification method provided in an embodiment of the present application, and the method includes the following steps S410 to S440.

[0073] Step S410, detecting the ambient temperature and humidity of the door body.

[0074] Step S420, determining the ambient dew point temperature according to the ambient temperature and ambient humidity of the door body.

[0075] Step S430, when the ambient dew point temperature reaches a preset dew point temperature threshold and the ambient humidity reaches a preset first humidity threshold, the air conditioning system is turned on to dehumidify the refrigerator.

[0076] Step S440, after the air conditioning system is turned on, when it is determined that the ambient humidity reaches a preset second humidity threshold, the air conditioning system is turned off and dehumidification of the refrigerator is stopped; the second humidity threshold is less than the first humidity threshold.

[0077] The above method automatically controls the start and stop of the refrigerator air conditioning system according to the ambient temperature and humidity to achieve the dehumidification function.

[0078] In one specific embodiment, Figure 5 Schematic diagram of the dehumidification determination process provided by this specific embodiment. Figure 5 Assuming that the surface temperature of the door is 16°C, when the ambient temperature is lower than 16°C, the probability of condensation on the refrigerator door is small, and the air inlet of the dehumidification duct is normally closed. Only when the ambient temperature is higher than 16°C, the refrigerator door is prone to condensation. However, due to the differences in the corresponding dew point temperatures under different ambient temperatures and different ambient humidities, it is necessary to judge the opening or closing of the dehumidification duct inlet according to different ambient temperatures and ambient humidities.

The air suction fan is started at the same time to dehumidify the refrigerator door. When the ambient humidity sensor detects in real time that the relative humidity reaches 50%, the dehumidification air duct is controlled to be closed. At this time, the air suction fan stops working, indicating that the dehumidification of the refrigerator door has been completed. At the same time, the temperature sensor continuously detects the ambient temperature and humidity of the refrigerator to determine whether the current ambient temperature of the refrigerator is higher than the surface temperature of the door.
