[0067] Humidity is an important factor affecting the shelf life and quality of fruits and vegetables. Maintaining a high humidity environment is conducive to the long-term storage of fruits and vegetables and the retention of nutrients, and humidification is an important means to maintain a high humidity environment.

[0068] Among the humidification methods in the related technologies, passive humidification has problems such as large dry consumption of fruits and vegetables and slow humidification rate. Most liquid mist humidification requires users to manually replenish water at regular intervals. If the humidified gas is not condensed, it is easy to contain too much water, which is easy to form condensation on the surface of fruits and vegetables, which is not conducive to the preservation of fruits and vegetables. Volatile humidification has the problem that users need to replenish water regularly or the transpiration of fruits and vegetables themselves is provided, the humidification effect is not good, and the humidity cannot be maintained at a high level.

[0069] In view of this, an embodiment of the present disclosure provides a refrigerator capable of improving humidification capacity.

[0070] Figure 1 is a schematic diagram of the structure of some embodiments of the refrigerator according to the present disclosure, referring to Figure 1 The refrigerator includes a box body, a refrigeration air duct assembly 2, a fan 3 and a surface cooler 4.

[0071] A refrigerating chamber 1 is provided in the box body, and the refrigerating chamber 1 includes but is not limited to one or more refrigerating drawers 11 . The refrigerating drawers 11 are used for refrigerating fruits, vegetables and other items to keep the freshness of the items stored in the refrigerating drawers 11 .

[0072] The refrigeration duct assembly 2 is arranged in the box body, and the excess cold capacity of the refrigeration refrigeration can be provided to the surface cooler 4 by the refrigeration duct assembly 2. The cold air of the refrigeration refrigeration flows in the refrigeration duct assembly 2, and is used to distribute the cold air to control the temperature of the refrigerator. The refrigeration duct assembly 2 has a duct cover plate 21.

[0073] The fan 3 is disposed in the box body and is configured to introduce air from the outside and move the air to the refrigerating chamber 1. The fan 3 includes but is not limited to a fresh air fan, which can be disposed on the rear wall of the refrigerator. The high-temperature and high-humidity air from the outside is sent into the interlayer between the air duct cover plate 21 of the refrigerating air duct assembly 2 and the refrigerating chamber 1 under the wind pressure formed by the operation of the fan 3.

[0074] The surface cooler 4 is arranged in the box, close to the refrigeration air duct assembly 2, and located on the path of the gas moving from the fan 3 to the refrigeration chamber 1. The surface cooler 4 is configured to obtain cold energy from the refrigeration air duct assembly 2 and exchange heat with the gas to make the gas humidify the refrigeration chamber.

[0075] The excess cold energy of the refrigeration duct assembly 2 during refrigeration is provided to the surface cooler 4, so that the temperature of the surface cooler 4 drops to a temperature lower than that of the refrigeration chamber 1. The surface cooler 4 includes but is not limited to extending along the extension direction of the refrigeration duct assembly 2 and abutting against the refrigeration duct assembly 2, so as to increase the contact area with the refrigeration duct assembly 2 and reduce the loss of cold energy during the transmission process.

[0076] In this embodiment, external air is introduced through the fan 3 and cooled by the surface cooler 4. The cooled air enters the refrigerated drawer 11 of the refrigerating chamber 1 to humidify the stored items, so that the refrigerating chamber 1 can have a long-term and stable humidification source, and can provide a high-humidity environment for fruits, vegetables and other items stored in the refrigerating chamber, reduce the dryness of fruits and vegetables, and save users from the operation of frequently adding water for humidification, thereby improving the humidification and preservation ability of the refrigerator.

[0077] refer to Figure 1 In some embodiments, the refrigerator further comprises a guide member 5, which is arranged near the air outlet of the fan 3 and is configured to guide the gas to move toward the surface cooler 4. Figure 1 As shown in A.

[0078] The guide member 5 is directly opposite to the air outlet of the fan 3, and the extension direction of the guide member 5 is close to the surface cooler 4, and forms a certain angle with the air outlet direction of the fan 3, thereby guiding the gas discharged by the fan 3 to move from the gap between the guide member 5 and the fan 3 to the surface cooler 4 along the extension direction of the guide member 5.

[0079] In this embodiment, by providing a guide member 5 to guide the gas to move more concentratedly toward the working surface of the surface cooler 4, the heat exchange efficiency between the gas and the surface cooler 4 can be improved, thereby improving the humidification capacity of the refrigerator to provide a stable high-humidity environment for the storage of fruits and vegetables.

[0080] refer to Figure 1 In some embodiments, the guide member 5 is rotatably connected to the refrigerating chamber 1 to guide the gas to move to different positions of the working surface of the surface cooler 4. The guide member 5 can be arranged on the rear wall of the refrigerating drawer 11 of the refrigerating chamber 1 and rotatably connected to the refrigerating drawer 11.

[0081] A rotating shaft is set at the end of the guide member 5, and the rotating shaft can be driven by a motor to drive the guide member 5 to rotate, thereby adjusting the angle between the guide member 5 and the air outlet direction of the fan 3, adjusting the size of the gap between the guide member 5 and the fan 3, and then guiding the gas to move to different positions on the working surface of the surface cooler 4.

[0082] When the guide member 5 rotates toward the direction close to the fan 3, that is, Figure 1 As shown in the figure, the gap between the guide member 5 and the fan 3 is reduced, and the gas exchanges heat with the working surface of the cooler 4 closer to the fan 3. At this time, the heat exchange area between the gas and the cooler 4 is reduced.

[0083] When the guide member 5 rotates away from the fan 3, that is, Figure 1 As shown in the figure, the gap between the guide member 5 and the fan 3 increases, and the gas can exchange heat with the working surface of the cooler 4 which is farther away from the fan 3. At this time, the gas can generate a larger heat exchange area with the cooler 4.

[0084] In this embodiment, by adjusting the angle of the flow guide 5, the heat exchange area between the gas and the surface cooler 4 can be increased or decreased, and the temperature of the gas in the refrigerating chamber 1 can be specifically adjusted according to the humidification needs.

[0085] refer to Figure 1 In some embodiments, the refrigerator further includes a filter element 6, which is disposed on a moving path of the gas entering the refrigerating chamber 1 and is connected to the refrigerating chamber 1, and the filter element 6 has a plurality of pores.

[0086] The filter 6 is arranged on the path of the gas discharged from the fan 3 to the cold storage room. The filter 6 includes but is not limited to a porous medium layer, and the porous medium layer can be made of activated carbon. The gas enters the cold storage room through the filter 6 under the action of the wind pressure and osmotic pressure of the fan 3. The filter 6 includes but is not limited to a large number of pores, and the gas encounters greater resistance when passing through these pores, which can reduce the gas flow rate.

[0087] The gas will change direction multiple times when passing through the complex pores inside the filter element 6, thereby increasing the chances of collision between gases, promoting the diffusion process between different components, and further enhancing the gas mixing effect.

[0088] The large number of pores in the filter element 6 increases the opportunities for heat conduction and convection heat transfer for the gas, and because the flow rate of the gas is slowed down, more sufficient temperature and humidity exchange can be achieved.

[0089] In this embodiment, by setting up the filter element 6, the flow rate of the gas can be reduced, and the gas can be more fully mixed and the temperature and humidity exchanged when passing through can be achieved, so that the temperature and humidity of the gas entering the cold storage room 1 are more uniform. In addition, the filter element 6 can also absorb impurities in the gas to sterilize and deodorize the gas.

[0090] refer to Figure 1 In some embodiments, the refrigerator further includes a water collecting tank 7 , which is disposed near the fan 3 and configured to collect condensed water formed on the working surface of the surface cooler 4 .

[0091] The water collecting tank 7 includes but is not limited to being arranged below the surface cooler 4 and the fan 3. The condensed water formed by the heat exchange between the surface cooler 4 and the external air drips downward along the surface of the surface cooler 4 under the action of gravity and is collected by the water collecting tank 7. The water collecting tank 7 can be connected to the water receiving pan at the bottom of the refrigerator so that the condensed water collected by the water collecting tank 7 can be directed to the water receiving pan and evaporate in the water receiving pan and be discharged from the machine room.

[0092] In this embodiment, the water collecting tank 7 can collect the condensed water generated when the gas passes through the filter element 6 and the condensed water formed on the working surface of the surface cooler 4. By collecting the condensed water by the water collecting tank 7, the risk of condensed water accumulation affecting the safety of electrical equipment can be reduced, which helps to maintain the safe operation of the refrigerator.

[0093] Figure 2 is a connection diagram of some embodiments of the refrigerator according to the present disclosure, referring to Figure 1 and Figure 2 In some embodiments, the refrigerator further includes a detection device 8 and a processor 9.

[0094] The detection device 8 is configured to obtain the humidity in the refrigerating chamber 1 . The detection device 8 may include a first sensor 81 . The first sensor 81 includes but is not limited to being arranged in the refrigerating chamber 1 to obtain an average humidity value of the refrigerating chamber 1 within a preset time.

[0095] The detection device 8 includes but is not limited to starting to detect the temperature and humidity status of the refrigerator chamber 1 when the refrigeration is about to end. At this time, the temperature and humidity in the refrigerator chamber 1 are at the lowest value in the refrigeration operation cycle, so as to more accurately evaluate the storage conditions of fruits and vegetables in the refrigerator chamber 1.

[0096] The processor 9 is connected to the detection device 8 and the fan 3 signals, and is configured to enable the fan 3 to introduce gas from the outside to increase the humidity in the refrigeration chamber 1 in response to the humidity of the refrigeration chamber 1 obtained by the detection device 8 being less than a preset humidity.

[0097] The refrigerator includes but is not limited to humidifying the refrigerator compartment 1 after the refrigeration is completed, when the temperature of the refrigerator compartment 1 is at the lowest value. If the humidification causes the temperature of the refrigerator compartment 1 to rise too high, the humidification can be stopped and the humidification operation can be performed after the next round of refrigeration is completed.

[0098] In this embodiment, by providing a detection device 8 and a processor 9, the humidity state in the cold storage room 1 can be accurately obtained. When the humidity in the cold storage room 1 is lower than a preset value, the fan 3 is used to introduce outside air to humidify the cold storage room 1, thereby providing a reliable temperature and humidity environment for the items stored in the cold storage room 1.

[0099] In some embodiments, the detection device 8 is configured to obtain the temperature of the condenser 4. The detection device 8 may further include a second sensor 82, which can obtain the temperature of the condenser 4.

[0100] The processor 9 is also configured to: in response to the humidity of the cold storage chamber 1 obtained by the detection device 8 being less than the preset humidity, obtain the temperature of the cooler 4 through the detection device 8; in response to the temperature of the cooler 4 being less than or equal to the first preset temperature, enable the fan 3 to introduce gas from the outside, and / or in response to the temperature of the cooler 4 being greater than the first preset temperature, wait for the cooler 4 to exchange heat and cool down with the refrigeration air duct assembly 2 until the temperature of the cooler 4 is less than or equal to the first preset temperature, allowing the fan 3 to introduce gas from the outside.

[0101] When the humidity of the refrigerator compartment 1 is lower than the preset humidity, the refrigerator compartment 1 needs to be humidified. At this time, the temperature of the cooler 4 is obtained by the detection device 8 to determine whether the cooler 4 has the ability to cool the gas inhaled from the outside.

[0102] When the temperature of the cooler 4 is less than or equal to the first preset temperature, the cooler 4 has sufficient cooling capacity to immediately cool down the gas sucked from the outside. At this time, the fan 3 can be directly turned on to introduce the outside air and perform convection heat exchange with the cooler 4.

[0103] When the temperature of the cooler 4 is greater than the first preset temperature, the temperature of the cooler 4 is too high to immediately cool down the gas sucked in from the outside. At this time, it is necessary to wait for the refrigeration duct assembly to provide enough cooling capacity to the cooler 4 so that the temperature of the cooler 4 is less than or equal to the first preset temperature before turning on the fan 3.

[0104] In this embodiment, the opening and closing of the fan 3 is controlled based on the relationship between the temperature of the surface cooler 4 and the first preset temperature, ensuring that the fan 3 is turned on after the temperature of the surface cooler 4 reaches the preset value. This can make the temperature and humidity of the gas entering the cold storage room 1 more stable, avoid drastic fluctuations in temperature and humidity, and accurately control the time for cooling the external air, optimize the dehumidification efficiency, and reduce additional energy consumption.

[0105] In some embodiments, the detection device 8 is configured to obtain the temperature of the humidified gas entering the refrigerating chamber 1 , and the first sensor 81 can also detect the temperature of the humidified gas so as to understand the condition of the gas after being cooled by the surface cooler 4 .

[0106] The humidified gas includes the gas introduced from the outside by the fan 3 and the gas that has been cooled by the surface cooler 4 through heat exchange. The humidified gas leaves the surface cooler 4 and enters the refrigerating chamber 1 to humidify the refrigerating chamber 1 .

[0107] The processor 9 is further configured to increase the rotation speed of the fan 3 in response to the temperature of the humidified gas obtained by the detection device 8 being greater than the second preset temperature, and / or to reduce the rotation speed of the fan 3 in response to the temperature of the humidified gas obtained by the detection device 8 being less than the third preset temperature. The third preset temperature is less than the second preset temperature.

[0108] When the temperature of the humidified gas is greater than the second preset temperature, the rotation speed of the fan 3 is increased to increase the heat exchange degree between the gas introduced from the outside and the surface cooler 4, thereby increasing the cooling capacity provided to the gas and reducing the temperature of the gas.

[0109] When the temperature of the humidified gas is lower than the third preset temperature, the rotation speed of the fan 3 is reduced, and the degree of heat exchange between the gas introduced from the outside and the surface cooler 4 is reduced, thereby reducing the cooling capacity provided to the gas, so as to increase the temperature of the gas and also increase the water vapor content in the gas.

[0110] In this embodiment, the heat exchange degree between the surface cooler 4 and the gas introduced from the outside is controlled by adjusting the rotation speed of the fan 3, and then the temperature of the humidified gas entering the refrigerating chamber 1 is accurately controlled, so as to provide a stable and suitable storage environment for the items stored in the refrigerating chamber 1 and prolong the freshness of the stored items.

[0111] In some embodiments, the processor 9 is also configured to adjust the angle between the guide member 5 and the air outlet direction of the fan 3 in response to the temperature of the humidified gas being greater than a second preset temperature, so as to guide the gas introduced from the outside to exchange heat with the working surface of the surface cooler 4 farther away from the air outlet of the fan 3.

[0112] When the temperature of the humidified gas is greater than the second preset temperature, the flow guide 5 can be rotated counterclockwise, that is, in a direction away from the fan 3, so that the gas discharged by the fan 3 can move to a position farther from the air outlet of the fan 3, thereby allowing the fan 3 to achieve a wider range of contact with the working surface of the cooler 4, thereby improving the degree of cooling the gas. It can also reduce the interference of condensed water condensed on part of the working surface of the cooler 4 on the gas heat exchange.

[0113] In this embodiment, the contact between the gas and the working surface of the surface cooler 4 is adjusted by rotating the flow guide 5, so that the degree of cooling of the gas is adjusted, thereby improving the controllability of the humidification of the refrigerating chamber 1.

[0114] In some embodiments, the processor 9 is further configured to maintain the rotation speed of the fan 3 in response to the temperature of the humidified gas being equal to the average of the second preset temperature and the third preset temperature.

[0115] In this embodiment, when the temperature of the humidified gas is maintained at the average of the second preset temperature and the third preset temperature, the rotation speed of the fan 3 is maintained, and the temperature of the humidified gas is monitored in real time. If the temperature deviates from the preset value, the rotation speed of the fan 3 and / or the angle between the guide member 5 and the air outlet direction of the fan 3 are adjusted to maintain a stable temperature and humidity environment and improve the moisturizing effect of stored items such as fruits and vegetables.

[0116] Figure 3 is a flow chart of some embodiments of the gaseous humidification control method disclosed in the present invention, with reference to Figure 1 and Figure 3 In another aspect of the embodiments of the present disclosure, a gas humidification control method for a refrigerator based on any embodiment is provided, comprising: step S1 to step S2.

[0117] In step S1 , the humidity in the refrigerating chamber 1 is obtained.

[0118] In step S2, in response to the humidity of the refrigerating chamber 1 being lower than a preset humidity, when the humidity of the refrigerating chamber 1 is lower than the preset humidity, the refrigerating chamber 1 has a need for humidification, so that the fan 3 introduces air from the outside.

[0119] In this embodiment, the humidity state in the cold storage room 1 is grasped by acquiring the humidity in the cold storage room 1. When the humidity in the cold storage room 1 is less than a preset value, the fan 3 is used to introduce outside air to humidify the cold storage room 1, thereby providing a humidity environment with a reliable temperature for the items stored in the cold storage room 1.

[0120] In some embodiments, in response to the humidity of the cold storage chamber 1 being less than a preset humidity, the operation of causing the fan 3 to introduce gas from the outside specifically includes: obtaining the temperature of the cooler 4; in response to the temperature of the cooler 4 being less than or equal to a first preset temperature, causing the fan 3 to introduce gas from the outside, and / or in response to the temperature of the cooler 4 being greater than the first preset temperature, waiting for the cooler 4 to cool down, until the temperature of the cooler 4 is less than or equal to the first preset temperature, causing the fan 3 to introduce gas from the outside.

[0121] When the humidity of the refrigerating chamber 1 is lower than the preset humidity, the refrigerating chamber 1 needs to be humidified. At this time, the temperature of the surface cooler 4 is required to determine whether the surface cooler 4 has the ability to cool the gas inhaled from the outside.

[0122] When the temperature of the cooler 4 is less than or equal to the first preset temperature, the cooler 4 has sufficient cooling capacity to immediately cool down the gas sucked from the outside. At this time, the fan 3 can be directly turned on to introduce the outside air and perform convection heat exchange with the cooler 4.

[0123] When the temperature of the cooler 4 is greater than the first preset temperature, the temperature of the cooler 4 is too high to immediately cool down the gas sucked in from the outside. At this time, it is necessary to wait for the refrigeration duct assembly to provide enough cooling capacity to the cooler 4 so that the temperature of the cooler 4 is less than or equal to the first preset temperature before turning on the fan 3.

[0124] In this embodiment, the opening and closing of the fan 3 is controlled based on the relationship between the temperature of the surface cooler 4 and the first preset temperature, ensuring that the fan 3 is turned on after the temperature of the surface cooler 4 reaches the preset value. This can make the temperature and humidity of the gas entering the cold storage room 1 more stable, avoid drastic fluctuations in temperature and humidity, and accurately control the time for cooling the external air, optimize the dehumidification efficiency, and reduce additional energy consumption.

[0125] In some embodiments, in response to the humidity of the refrigerating chamber 1 being lower than a preset humidity, the operation of causing the fan 3 to introduce gas from the outside also includes: obtaining the temperature of the humidified gas entering the refrigerating chamber 1; in response to the temperature of the humidified gas being higher than a second preset temperature or lower than a third preset temperature, adjusting the rotation speed of the fan 3 and / or adjusting the angle between the guide member 5 and the air outlet direction of the fan 3. The humidified gas includes the gas introduced from the outside by the fan 3 that has been heat exchanged with the surface cooler 4 and cooled down. The humidified gas leaves the surface cooler 4 and enters the refrigerating chamber 1 to humidify the refrigerating chamber 1.

[0126] When the temperature of the humidified gas is greater than the second preset temperature, the rotation speed of the fan 3 is increased, and the degree of heat exchange between the gas introduced from the outside and the surface cooler 4 is increased, thereby increasing the degree of refrigeration of the gas and reducing the temperature of the gas.

[0127] When the temperature of the humidified gas is lower than the third preset temperature, the rotation speed of the fan 3 is reduced, and the degree of heat exchange between the gas introduced from the outside and the surface cooler 4 is reduced, thereby reducing the degree of refrigeration of the gas, so as to increase the temperature of the gas and also increase the water vapor content in the gas.

[0128] When the temperature of the humidified gas is greater than the second preset temperature, the flow guide 5 can be rotated counterclockwise, that is, rotated in a direction away from the fan 3, so that the gas discharged by the fan 3 can move to a position farther from the air outlet of the fan 3, thereby allowing the fan 3 and the working surface of the cooler 4 to achieve a larger range of contact heat exchange, thereby improving the degree of cooling the gas. It can also reduce the interference of condensed water condensed on part of the working surface of the cooler 4 on the gas heat exchange.

[0129] When the gas temperature of the humidified gas is lower than the third preset temperature, the flow guide 5 can rotate clockwise, that is, rotate toward the direction close to the fan 3, so that the fan 3 and the working surface of the surface cooler 4 can be in contact with each other for heat exchange in a small range, thereby reducing the degree of cooling of the gas.

[0130] In this embodiment, by adjusting the rotation speed of the fan 3 and / or rotating the guide member 5, the contact heat exchange between the gas and the surface cooler 4 is adjusted, the cooling degree of the gas is accurately adjusted, and the controllability of the humidification of the cold storage chamber 1 is improved, so as to provide a stable and suitable storage environment for the items stored in the cold storage chamber 1 and extend the freshness maintenance time of the stored items.

[0131] refer to Figure 1 and Figure 3 , the gaseous humidification control method in some embodiments is given below:

[0132] During the actual operation, when the refrigeration is about to end, for example, about half a minute before the end of the refrigeration, the first sensor 81 starts to detect the state of the refrigeration chamber 1. When the sensor detects that the humidity of the refrigeration chamber 1 is less than the preset humidity, the humidification operation can be turned on: first, check whether the temperature of the cooler 4 has reached the first preset temperature. If the temperature of the cooler 4 is less than or equal to the first preset temperature, turn on the fan 3 directly to introduce the outside air and perform convection heat exchange with the cooler 4; if the temperature of the cooler 4 is greater than the first preset temperature, wait until the refrigeration air supply brings enough cold air to the cooler 4, so that the temperature of the cooler 4 is less than or equal to the first preset temperature before turning on the fan 3.

[0133] When the outside air is cooled, condensed and passes through the filter 6, the first sensor 81 will detect its temperature. If the temperature of the gas is lower than the third preset temperature, the rotation speed of the fan 3 will be reduced, thereby reducing the heat exchange between the outside air and the surface cooler 4, thereby reducing the cooling capacity, causing the temperature of the gas to rise above the third preset temperature, and also causing the water vapor content in the gas to increase.

[0134] On the contrary, if the temperature is greater than the second preset temperature, the speed of the fan 3 is increased to increase the heat exchange between the fan 3 and the cooler 4, increase the cooling capacity, and adjust the angle of the guide 5 to allow the air to exchange heat with the surfaces of the cooler 4 at different heights through convection, so as to prevent the condensed water condensed on the surface of the cooler 4 from dripping down and interfering with the heat exchange of the air below, and finally reduce the temperature of the gas to the average of the second preset temperature and the third preset temperature. Subsequently, the speed of the fan 3 is maintained, and the temperature of the gas is monitored in real time. If the temperature deviates from the preset range, the above operation is repeated until the humidity in the refrigerating chamber 1 is equal to the preset humidity.
