[0002] The storage of red wine generally requires storage in an appropriate humidity range to achieve better storage effects. Excessive humidity in the wine cabinet may cause the label paper of the wine bottle to be soaked by water droplets or the cork to mold. Through testing, it was found that under low ambient temperature or when the wine cabinet is set to a high temperature, the humidity in the wine cabinet will be high and exceed the most suitable humidity for red wine storage. At present, the dehumidification method of the wine cabinet mostly uses the evaporator cooling of the wine cabinet to condense the water vapor in the storage room into water, thereby reducing the relative humidity in the storage room. However, in the two environments mentioned above, in order to reach the set temperature of the wine cabinet, the evaporator cooling time is short, which is not enough to reduce the humidity to a suitable humidity.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] In the related art, the refrigeration equipment includes a refrigeration assembly, which is the core part of the refrigeration system and is responsible for transferring heat from the low-temperature area to the high-temperature area, thereby achieving a refrigeration effect. The refrigeration assembly usually includes components such as a compressor, a condenser, a throttling device and an evaporator. The compressor is the heart of the refrigeration system and is responsible for compressing the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas. In this process, the temperature and pressure of the refrigerant will increase significantly. In the condenser, the high-temperature and high-pressure refrigerant gas is cooled down by heat dissipation and converted into a high-pressure liquid. This process is usually accompanied by the release of heat to the external environment. The function of the throttling device is to reduce the pressure and temperature of the refrigerant so that it can absorb more heat when it enters the evaporator. Common throttling devices include capillaries and electronic expansion valves. In the evaporator, the low-temperature and low-pressure refrigerant liquid absorbs heat from the surrounding environment and evaporates into gas, thereby achieving a refrigeration effect.

[0030] When storing wine in refrigeration equipment, it is generally necessary to keep it within the set range. Too high or too low a temperature will accelerate the aging process of the wine and affect its quality and taste. For example, wine usually needs to be stored in a constant temperature, constant humidity, light-proof, and quiet environment between 15°C and 20°C. If the storage temperature is too high, the wine may age faster and lose some of its fruity or other aromas. When the temperature reaches 28°C, the cork may be damaged, and oxygen will enter the bottle through the gap in the bottle mouth, affecting the quality of the wine. In a low temperature environment (below 5°C), the wine will slowly precipitate tartaric acid, and tannin particles will also precipitate faster, which will affect the taste and color of the wine. If the storage temperature is too low, the wine may freeze and increase in volume, resulting in the risk of the cork being pushed out or the bottle breaking.

[0031] During the refrigeration process, the moisture in the air will condense into water droplets, causing the humidity to drop. Therefore, the length of the refrigeration time directly affects the change in humidity. The greater the refrigeration power, the faster the refrigeration speed, but it will also cause more moisture to condense and the humidity to drop faster. Choosing the right refrigeration power can not only effectively reduce the temperature but also avoid too low humidity, which is the key to ensuring the quality of red wine storage.

[0032] In a high temperature environment, the temperature difference between the outside and inside of the refrigeration equipment is large, requiring the refrigeration components to work more frequently to maintain the set low temperature. In this process, the refrigeration time is longer, causing more water to condense into water droplets, resulting in a decrease in humidity.

[0033] However, when the ambient temperature of the refrigeration equipment is low, the temperature difference between the outside and inside of the refrigeration equipment is small. In order to prevent the temperature inside the refrigeration equipment from exceeding the set range, the working time of the refrigeration component needs to be shortened, which results in less water condensing into water droplets, which is not enough to reduce the humidity to an appropriate humidity.

[0034] In addition, when the set temperature of the refrigeration equipment is higher, the refrigeration component only needs to be turned on for a shorter time to reach the set temperature range, which will also cause the amount of water condensing into water droplets to decrease, and the humidity in the refrigeration equipment will be higher and exceed the most suitable humidity for red wine storage.

[0035] Refer to the following Figures 1 to 7 , illustrating how the refrigeration equipment and control method of the embodiments of the present invention solve the dehumidification problem in the two environments mentioned above.

[0036] Reference Figure 1 As shown, it can be understood that the refrigeration device of the embodiment of the present invention includes a cabinet 101, a refrigeration assembly and a fan 102. The cabinet 101 is provided with a storage compartment 103, a heat exchange cavity 104 and an air duct cavity 105. The storage compartment 103 is used to store items. The refrigeration assembly is used to provide a refrigeration environment for the storage compartment 103. The refrigeration assembly includes an evaporator 106 and a compressor. The evaporator 106 is arranged in the heat exchange cavity 104. The fan 102 and the refrigeration assembly cooperate with each other to generate a cooling airflow, and promote the cooling airflow to be sent to the storage compartment 103 through the air duct cavity 105. The heat exchange chamber 104 is connected to the air duct chamber 105, and the storage compartment 103 is provided with an air outlet 107 and an air return port 108. The air outlet 107 is connected to the air duct chamber 105, and the air return port 108 is connected to the heat exchange chamber 104. The storage compartment 103, the heat exchange chamber 104 and the air duct chamber 105 form a refrigeration path; the fan 102 is arranged on the refrigeration path and is used to promote air circulation along the refrigeration path.

[0037] During the refrigeration process, the evaporator 106 generates cold energy, and the fan 102 rotates to generate airflow. The direction of the airflow can be referred to as Figure 1 In the direction of the dotted arrow, the airflow brings the coldness of the evaporator 106 into the storage room 103 through the air duct cavity 105, and the airflow in the storage room 103 circulates back to the heat exchange cavity 104, thereby exchanging heat with the evaporator 106. After the airflow exchanges heat with the evaporator 106, its temperature decreases, and then it is sent into the storage room 103 again by the fan 102, and flows in this cycle, thereby achieving the effect of air cooling. Specifically, along the direction of the airflow flowing between the storage room 103, the heat exchange cavity 104 and the air duct cavity 105, a cooling path will be formed, and the fan 102 is located in the cooling path. The fan 102 is generally arranged in the heat exchange cavity 104 or the air duct cavity 105.

[0038] It can be understood that during the operation of the refrigeration component, the high-humidity air in the storage room 103 enters the heat exchange chamber 104 through the return air port 108 under the action of the circulating airflow. When passing through the evaporator 106, part of the moisture will condense into water, that is, the humidity in the circulating airflow is reduced, and then the airflow with reduced humidity enters the storage room 103 again, and the cycle is repeated in this way to achieve the purpose of reducing the relative humidity in the storage room 103.

[0039] Reference Figure 1 As shown, it can be understood that the refrigeration device of the embodiment of the present invention further includes a heating device 109, and the heating device 109 is arranged in the refrigeration path, so that during the refrigeration process, the airflow generated by the rotation of the fan 102 can pass through the heating device 109, and then the heat generated by the operation of the heating device 109 is mixed with the cold generated by the operation of the refrigeration component, and then heat is exchanged, so that the rate of temperature reduction in the storage room 103 is slowed down, so that the operation of the refrigeration component has less impact on the temperature of the storage room 103, that is, the rate of temperature reduction in the storage room 103 is slower, and finally the working time of the refrigeration component can be extended, and the effect of reducing humidity can be improved.

[0040] It is understandable that the refrigeration device of the embodiment of the present invention further includes a control device, which is connected to the refrigeration component and the heating device 109 in communication. For example, the control device and the compressor can be connected in a wired or wireless manner, and the control device and the heating device 109 can be connected in a wired or wireless manner. Among them, the wired communication connection can be a wire connection, and the wireless communication can be a Bluetooth connection, a local area network connection, and an Internet connection. When the humidity in the storage room 103 is high, the refrigeration device enters the dehumidification mode, and the control device controls the refrigeration component and the heating device 109 to start. The refrigeration component and the heating device 109 are used in combination to reduce the temperature effect of the refrigeration airflow on the items in the storage room 103, extend the working time of the refrigeration component, and then extend the dehumidification time, and improve the dehumidification effect. In particular, the humidity in the storage room 103 can be kept in a high temperature environment, or when the storage room 103 is set to a high temperature, the refrigeration device can also maintain a long refrigeration process, effectively reducing the humidity in the storage room 103.

[0041] It can be understood that the refrigeration equipment in the embodiment of the present invention may specifically be a refrigerator, a wine cabinet or other products.

[0042] Reference Figure 1As shown, it can be understood that the heating device 109 is located in the air duct cavity 105, so that the high-humidity air entering the heat exchange cavity 104 from the storage compartment 103 first passes through the evaporator 106, becomes low-temperature and low-humidity air after condensation, and then passes through the heating device 109 to become medium-temperature and medium-humidity air, and finally enters the storage compartment 103. Specifically, the high-humidity air contains more water vapor. When the high-humidity air flows through the evaporator 106, the water vapor in the air will exchange heat with the surface of the evaporator 106. Since the temperature on the surface of the evaporator 106 is relatively low, the water vapor will release latent heat and condense into liquid water, which will flow along the drainage system and eventually be discharged into the water receiving tray through the drainage system. As the water vapor condenses, the humidity in the air will be significantly reduced, thereby achieving a dehumidification effect. Since the evaporation process requires the absorption of heat, the temperature on the surface of the evaporator 106 will decrease, thereby causing the temperature of the air flowing through the evaporator 106 to also decrease. The air then passes through the heating device 109, and the temperature of the air passing through the heating device 109 is increased through heat exchange with the heating device 109. Finally, the temperature of the air is substantially consistent with the temperature of the air in the storage compartment 103. In other words, after the air passing through the evaporator 106 and the heating device 109 enters the storage compartment 103, the inlet and outlet temperatures can be controlled to be relatively consistent, but the humidity has a significant change, and the temperature fluctuation in the storage compartment 103 is small, which has little impact on the quality of the items.

[0043] It should be noted that the heating device 109 can also be located in the heat exchange cavity 104. The heating device 109 is located in the heat exchange cavity 104 or in the air duct cavity 105, both of which are located on the side away from the storage compartment 103, so as to avoid the heat generated by the heating device 109 being directly transferred to the items in the storage compartment 103, thereby reducing the temperature fluctuation of the items and reducing the impact on the quality of the items.

[0044] Reference Figure 1 As shown, it can be understood that the heating device 109 is located between the evaporator 106 and the air outlet 107, and the fan 102 is located between the evaporator 106 and the heating device 109. The location of the heating device 109 is far away from the evaporator 106, which can reduce the influence of the heat of the heating device 109 on the condensation process, and the dehumidification and cooling process is performed first, and then the heating process is performed, so as to ensure the smooth progress of the dehumidification process. The fan 102 is located on the side of the evaporator 106 away from the return air outlet 108, and the airflow passes through the evaporator 106 by exhausting air, so that the airflow passes through the evaporator 106 more evenly, realizing uniform heat exchange of the airflow and improving the effect of reducing humidity.

[0045] Reference Figure 1As shown, it can be understood that the heat exchange chamber 104 is located at the rear side of the storage compartment 103, and the return air port 108 is located at the rear wall 112 of the storage compartment 103. The heat exchange chamber 104 is closer to the return air port 108, so the return air distance can be shortened. The air outlet 107 is located at the top wall 111 of the storage compartment 103, and the air outlet 107 is connected to the air duct chamber 105, that is, at least part of the air duct chamber 105 is located on the upper side of the storage compartment 103, and the distance between the air outlet 107 and the return air port 108 is relatively far. Moreover, the evaporator 106 is arranged in the heat exchange cavity 104, the heating device 109 is located in the air duct cavity 105, and the heating device 109 is located on the upper side of the storage compartment 103. The evaporator 106 and the heating device 109 are respectively arranged in different areas of the storage compartment 103. The inner walls of the air duct cavity 105 and the heat exchange cavity 104 can block the heat radiation of the heating device 109, and the distance between the two is relatively far, which helps the high-humidity gas to be heated to a temperature close to the storage compartment 103 after a sufficient condensation and cooling process, avoiding interference caused by the close distance between the evaporator 106 and the heating device 109.

[0046] Reference Figure 1 and Figure 2 As shown, it can be understood that there are multiple air outlets 107, and the multiple air outlets 107 are spaced apart along the depth direction of the refrigeration equipment. It can also be understood that the air outlets 107 are divided into multiple groups, and each group of air outlets 107 is spaced apart along the front and back direction of the refrigeration equipment, which can help improve the uniformity of air outlet.

[0047] In the related art, the back-outlet air outlet method is prone to uneven temperature problems. When a large amount of food is stored, the food near the air outlet is prone to overfreezing, while the temperature of the food far away from the air outlet and close to the front of the compartment is relatively high, posing a risk of poor preservation effect.

[0048] In this embodiment, multiple air outlets 107 are located above the storage compartment 103, which can form an airflow from top to bottom into the storage compartment 103, which is beneficial to reduce the difference in cold air flow distance of each air outlet 107, thereby making the temperature reduction amplitude at each position nearly consistent.

[0049] It is understandable that in the related art, the refrigeration temperature of the wine cabinet will not be very low. The optimal storage temperature of red wine is generally between 12°C and 18°C, the suitable refrigeration temperature of white wine is generally 8°C to 10°C, and the suitable storage temperature of sparkling wine, such as champagne, is generally 6°C to 10°C. Therefore, the frost severity of the evaporator 106 of the wine cabinet is not high, and it is generally defrosted by natural defrosting, which uses the natural temperature changes of the ambient temperature and the inside of the wine cabinet to remove the frost layer. The advantage of natural defrosting is that no additional energy consumption is required and the maintenance cost is low, but the disadvantage is that the defrosting process may be longer.

[0050] It is understandable that when the refrigeration device of the embodiment of the present invention is in the dehumidification mode, the heating power of the heating device 109 is 25 watts to 35 watts. The heating power of the heating device 109 is relatively small, which avoids the heating device 109 from having a significant impact on the temperature of the storage compartment 103, and the heating device 109 is turned on in the dehumidification mode, that is, the heating device 109 and the refrigeration component work together to reduce the impact on the temperature of the storage compartment 103.

[0051] In the related art, refrigerators and other products are equipped with defrost heating wires to accelerate the defrosting process. The defrost heating wire is usually installed on the evaporator 106, or located near the evaporator 106. When the frost layer accumulates to a certain extent, the defrost heating wire will start and heat up to melt the frost layer quickly. When the defrosting conditions are met, the intelligent control system will stop the refrigeration function of the refrigerator by closing the refrigeration cycle, so that the evaporator 106 will no longer continue to cool down. The heat generated by the defrost heating wire is transferred to the surface of the evaporator 106, so that the frost layer on the surface of the evaporator 106 gradually melts. During the defrosting process, the temperature of the defrost heating wire is usually controlled within a suitable range to ensure that it can effectively defrost without causing damage to the evaporator 106. For example, the power of the defrost heating wire used for general defrosting is 110 watts. It is understandable that if the wine cabinet uses a defrost heating wire for defrosting, the local temperature in the wine cabinet may rise, affecting the taste and quality of the wine.

[0052] It can be seen that the start timing and working power of the heating device 109 in the embodiment of the present invention are different from those of the heating wire of the existing refrigeration equipment, so that the humidity can be reduced without causing obvious fluctuations in the temperature of the storage compartment 103.

[0053] Reference Figure 1 As shown, it can be understood that the refrigeration equipment of the embodiment of the present invention also includes a humidifying component 110, and the humidifying component 110 is arranged in the storage compartment 103. The humidifying component 110 includes a water storage component, and liquid can be stored in the water storage component. The humidifying component 110 can increase the humidity of the storage compartment 103 by natural evaporation of the liquid. The humidifying component 110 also includes a humidifying fan, and the air outlet 107 of the humidifying fan faces the water storage component. After the humidifying fan is started, a conveying airflow is generated, so that the conveying airflow passes through the water storage component to take away the moisture of the water storage component, thereby forming high-humidity air, which enters the target space and mixes with the air in the storage compartment 103, thereby increasing the humidity of the storage compartment 103.

[0054] The embodiment of the present invention provides a control method for refrigeration equipment, which is applied to the control device provided in the refrigeration equipment in the above embodiment, wherein the function or connection relationship of the control device has been described in detail in the above embodiment and will not be repeated here. Figure 3 As shown, the control method of the embodiment of the present invention includes but is not limited to step S301, step S302, and step S303.

[0055] Step S301, detecting the current humidity of the storage room.

[0056] In one embodiment, a humidity sensor is disposed on the cabinet, and the humidity sensor is used to detect the humidity of the storage compartment, that is, the current humidity of the storage compartment is detected by the humidity sensor.

[0057] In another embodiment, the humidity sensor may also be disposed on the humidifying component.

[0058] Step S302, detecting the current temperature of the storage compartment.

[0059] In one embodiment, a temperature sensor is disposed on the cabinet, and the temperature sensor is used to detect the temperature of the storage compartment, that is, the current temperature of the storage compartment is detected by the temperature sensor.

[0060] Step S303, controlling the opening and closing of the refrigeration component and the heating device according to the current humidity and the current temperature. If the current humidity is greater than the preset humidity value and the current temperature is greater than the preset temperature value, the refrigeration component and the heating device are controlled to start.

[0061] In one embodiment, the preset humidity value and the preset temperature value are input by the user.

[0062] In another embodiment, the preset humidity value and the preset temperature value are called from a program stored in the refrigeration device, and the dehumidification mode needs to be turned on to dehumidify the storage compartment to reduce the humidity.

[0063] If the current humidity is greater than the preset humidity value, it indicates that the humidity in the storage room is too high and exceeds the optimal humidity maintenance range. If the current temperature is greater than the preset temperature value, it indicates that the temperature in the storage room has room to drop, and even if the refrigeration component is turned on for a short time, it will not fall below the normal storage temperature required for the items.

[0064] It should be noted that the preset temperature value may be the upper limit of the storage temperature range required for the item, or may be greater than or slightly less than the upper limit of the storage temperature range required for the item. For example, if the storage temperature range required for the item is 10°C to 14°C, the preset temperature value may be 14°C, 14.5°C, or 13.8°C.

[0065] The refrigeration component and the heating device are controlled to start. The refrigeration component and the heating device can be started at the same time, or the heating device can be started first, and the heating device can be allowed to work for a period of time before the refrigeration component is started. The refrigeration component can also be started first and then the heating device is started.

[0066] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Figure 4 As shown, Figure 4 yes Figure 3 FIG. 4 is a schematic diagram of an embodiment of a detailed process of step S303 in FIG. 4 , wherein the control method of the embodiment of the present invention includes but is not limited to step S401.

[0067] Step S401: If the current temperature is lower than a preset temperature value, the refrigeration component is controlled to be turned off.

[0068] It is understandable that during the dehumidification process, the refrigeration component needs to remain turned on for dehumidification. When the temperature sensor detects that the temperature of the storage room is lower than the preset temperature value, continuing to turn on the refrigeration component for cooling will cause the temperature of the storage room to continue to drop, affecting temperature control. Therefore, the refrigeration component is controlled to be turned off here. When there is a conflict between humidity control and temperature control, the temperature requirement is given priority.

[0069] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Figure 5 As shown, Figure 5 yes Figure 3 FIG. 5 is a schematic diagram of an embodiment of a detailed process of step S303 in FIG. 5 , wherein the control method of the embodiment of the present invention includes but is not limited to step S501.

[0070] Step S501, after controlling the heating device to start and run for a preset time, controlling the refrigeration component to start.

[0071] It is understandable that after the heating device is started and runs for a preset period of time, the temperature in the storage space can rise slightly. When the refrigeration component is started, it will not cause a large drop in temperature, especially for wine. If the storage temperature is too low, the wine may freeze and increase in volume, resulting in the risk of the cork being pushed out or the bottle breaking. In addition, the slightly increased temperature in the storage space can help the water vapor in the air to condense better after the air enters the heat exchange cavity. The temperature difference is the driving force for the condensation of water vapor in the air. When there is a temperature difference between hot air and cold air, the water vapor in the hot air may reach saturation when it encounters cold air or a low-temperature object, and then condense into condensed water. The greater the temperature difference, the easier it is for the water vapor in the hot air to reach saturation and condense when it encounters cold air.

[0072] The embodiment of the present invention provides another control method for refrigeration equipment. Figure 6 As shown, the control method of the embodiment of the present invention includes but is not limited to step S601 and step S602.

[0073] Step S601, detecting the current humidity of the storage room.

[0074] In one embodiment, a humidity sensor is disposed on the cabinet, and the humidity sensor is used to detect the humidity of the storage compartment, that is, the current humidity of the storage compartment is detected by the humidity sensor.

[0075] In another embodiment, the humidity sensor may also be disposed on the humidifying component.

[0076] Step S602: If the current humidity is greater than the preset humidity value and the cooling component is in the on state, the heating device is controlled to start.

[0077] If the current humidity is greater than the preset humidity value, it indicates that the humidity in the storage room is too high and exceeds the optimal humidity maintenance range, and the humidity needs to be lowered. The refrigeration component is in the on state, indicating that the refrigeration equipment is working in the refrigeration mode. Keep the refrigeration component in the on state, and turn on the heating device at the same time to cool the air through the evaporator, so that the water vapor in the air condenses into water droplets, thereby achieving the dual effects of cooling and dehumidification. In this process, the temperature sensor monitors the temperature in the storage room in real time. When the shutdown point (the minimum value of the set temperature range) is reached, the refrigeration component is controlled to shut down, giving priority to meeting the temperature control needs.

[0078] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Figure 7 As shown, Figure 7 This is a complete embodiment of the control method of the refrigeration equipment in which the default heating device and the refrigeration component are initially in the closed state, which is described below in conjunction with specific steps.

[0079] Detect the current humidity X of the storage room and compare it with the preset humidity value Y to determine the humidity of the storage room, confirm the current humidity range, control the working mode of the refrigeration equipment, and then perform corresponding control. If the current humidity X ≥ the preset humidity value Y, it indicates that the humidity of the storage space is too high, and the refrigeration equipment is controlled to be in dehumidification mode.

[0080] Detect the current temperature T of the storage room and compare it with the preset temperature value W to determine the temperature of the storage room, confirm the current temperature range, control the working mode of the refrigeration equipment, and then perform corresponding control. If the current temperature T ≥ the preset temperature value W, it indicates that the compressor has not reached the shutdown point and the evaporator can continue to refrigerate. Control the heating device to start and run for a preset time, so that the temperature of the storage room rises slightly, and control the refrigeration component to start refrigeration and dehumidification.

[0081] During the dehumidification process, the temperature and humidity changes are monitored in real time. If the current humidity X is less than the preset humidity value Y, it indicates that the humidity is within the target range, or is in a low humidity range, and the heating device can be turned off. If the current temperature T is less than the preset temperature value W, it indicates that the compressor has reached the shutdown point, and the refrigeration component is controlled to shut down to avoid adverse effects of temperature drops on items in the storage room.
