[0037] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which the same or similar elements or elements having the same or similar functions are denoted by the same or similar reference numerals throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present application, and should not be construed as limiting the present application.

If it is described as first, second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of indicated technical features.

[0040] In the description of the present application, unless otherwise explicitly limited, the words such as setting, mounting, connecting, etc. should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0041] In a low temperature environment, the humidity inside a refrigeration device is often reduced to a low level, causing the surface moisture of the items to evaporate, resulting in drying and quality degradation of the items. The humidifying assembly increases the humidity inside the device by releasing water vapor or atomized water droplets, thereby maintaining the moisture state of the items and preventing them from being damaged due to drying.

[0042] Taking a wine cooler as an example, the humidifying assembly in the wine cooler is a device designed to maintain a suitable humidity environment in the wine cooler. Red wine, in particular, needs to be stored in a constant humidity environment, which can prevent the cork from drying and the wine from evaporating, thereby maintaining the taste and quality of the wine. In short, the humidifying assembly of the wine cooler is to ensure that the wine does not become stale due to a too dry environment.

[0043] The active humidifying type humidifying assembly generally includes a humidifying fan and a water storage tank. Water or humidifying materials such as volcanic rock and non-woven fabric containing moisture are placed in the water storage tank. The humidifying fan is located at one end of the water storage tank and blows air towards the other end of the water storage tank. The humidifying fan brings high-humidity air in the water storage tank to the wine cooler. Due to limited space, the area of the humidifying assembly is also limited. On the air outlet path in the horizontal direction, there is only one layer of water storage tank, resulting in a small humidifying area and low humidifying efficiency.

[0044] The following refers to Figures 1 to 9 how the humidifying assembly 100 and the refrigeration device of the embodiments of the present application solve the above problems.

[0045] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it can be understood that the humidifying assembly 100 of an embodiment of the present application comprises a housing 101, a first water storage member 115, a second water storage member 102, a first fan 103 and a cover plate 104. The housing 101 is provided with a first mounting groove 105 and a second mounting groove 106. A partition 107 is arranged between the first mounting groove 105 and the second mounting groove 106. The partition 107 is located at the bottom of the first mounting groove 105 and the second mounting groove 106, so that the bottom of the first mounting groove 105 and the second mounting groove 106 cannot be connected, while the top of the first mounting groove 105 and the second mounting groove 106 can be connected. The first fan 103 is arranged in the first mounting groove 105, and the first water storage member 115 and the second water storage member 102 are arranged in the second mounting groove 106. The first water storage member 115 and the second water storage member 102 are water boxes, which store liquid. The top of the water box is open, so that the liquid in the water box is in contact with the airflow blown by the first fan 103. The second water storage member 102 is integrally formed with the housing 101 and becomes a part of the housing 101. The first water storage member 115 is separately arranged in the second mounting groove 106, that is, the first water storage member 115 is an independent element. It can be understood that the first water storage member 115 and the second water storage member 102 can also be integrally formed with the housing 101 at the same time, or be independent elements at the same time.

[0046] Referring to Figures 1 to 3 As shown, the cover plate 104 is connected to the housing 101 and located above the first mounting groove 105 and the second mounting groove 106. There is a gap between the cover plate 104 and the housing 101 to form a humidifying channel 302. The cover plate 104 is provided with a first air outlet 108. The area where the first air outlet 108 is located is defined as an air outlet area. The high-humidity air flows out from the first air outlet 108. Specifically, the humidifying channel 302 comprises a first channel 303 and a second channel 304. The first channel 303 is located between the first water storage member 115 and the cover plate 104, and the second channel 304 is located between the first water storage member 115 and the second water storage member 102. The first channel 303 and the second channel 304 are respectively connected to the first air outlet 108. The first water storage member 115 is placed in the second water storage member 102 and is in contact with the cover plate 104 to form the first channel 303. The second channel 304 is formed between the lower part of the first water storage member 115 and the second water storage member 102. The first water storage member 115 and the second water storage member 102 are arranged in the up-down direction, and the first channel 303 and the second channel 304 are arranged in the up-down direction. When the first fan 103 is powered on, the relatively dry air is sucked into the first fan 103 and accelerated. Then, the dry air quickly passes through the first channel 303 and the second channel 304, respectively, that is, passes through the surface of the liquid in the first water storage member 115 and the second water storage member 102, respectively. The air with high humidity on the surface of the liquid is quickly taken away from the first air outlet 108 on the cover plate 104 to the target space to mix with the air, thereby increasing the relative humidity of the target space.

[0047] It can be understood that the single-layer humidifying structure is improved to a double-layer humidifying structure along the flow path of the airflow, that is, the liquid surface area of the first water storage member 115 is added to the liquid surface area of the second water storage member 102, and the humidifying area is further increased. The horizontal space for installing the humidifying assembly 100 on the refrigeration equipment is small, and the area of the humidifying assembly 100 in the horizontal direction is not increased in the embodiment. When the height space for installing the humidifying assembly 100 on the refrigeration equipment is sufficient, the height space can be fully utilized by the humidifying assembly 100 in the embodiment.

[0048] In other embodiments, the first channel 303 and the second channel 304 can also be connected in series, that is, the airflow blown out by the first fan 103 first passes through the first channel 303, then passes through the second channel 304, and finally flows out from the first air outlet 108.

[0049] It should be noted that the first water storage member 115 and the second water storage member 102 can also include humidifying materials such as volcanic rocks and non-woven fabrics, that is, the humidifying materials can be porous and dense structure water-absorbing materials. The diameter and volume of the pores on the porous and dense structure water-absorbing materials are smaller than the diameter and volume of the normally falling water droplets, so that the water droplets cannot flow through the porous and dense structure water-absorbing materials, while the airflow can pass through. The airflow blown out by the first fan 103 enters the second mounting groove 106 from above the partition strip 107, contacts the humidifying material, and carries away the moisture stored in the humidifying material, thereby forming high-humidity air. When the first fan 103 is powered on, the relatively dry air is sucked into the first fan 103 and accelerated, and then the dry air quickly passes through the surface of the humidifying material and is blown out from the first air outlet 108. The humidifying material surface has high humidity, and the air is quickly taken away to the target space and mixed with the air, thereby increasing the relative humidity of the target space. After the humid air above the humidifying material is taken away, the humidifying material can quickly absorb the water at the bottom of the water storage member and evaporate above it (water vapor has small density), so that the air above the humidifying material maintains a high-humidity state. The first water storage member 115 and the second water storage member 102 can also be humidifiers, such as ultrasonic humidifiers and steam type (thermal evaporation) humidifiers. The ultrasonic humidifier uses a high-frequency vibrating ultrasonic transducer (usually a ceramic or metal element) to atomize water into micron-sized particles, which are then blown into the air by a fan. This technology does not generate heat, so it is called a “cool mist” humidifier. The steam type humidifier heats the water to boiling by a heating element, generates steam, and then releases the steam into the air. This type of humidifier is also called a “hot mist” humidifier.

[0050] It can be understood that in other embodiments, the first fan 103 can also be arranged outside the shell 101, and a first air inlet hole corresponding to the first fan 103 is arranged on the shell 101.

[0051] Referring toFigures 1 to 3 As shown, it can be understood that the second installation groove 106 is designed in a strip shape, which lengthens the length of the water storage member, so that the water surface area is larger, which helps to improve the evaporation rate of water. During the humidification process, more water molecules can be exposed to the air, thereby accelerating evaporation.

[0052] Referring to Figure 2 As shown, it can be understood that the number of first air outlets 108 of the humidifying assembly 100 is multiple, and the air outlet area is divided into a first air outlet area D1 and a second air outlet area D2, and the multiple first air outlets 108 are respectively distributed in the first air outlet area D1 and the second air outlet area D2. Along the airflow direction, the length of the first water storage member 115 is less than the length of the second water storage member 102, so that the airflow in the first channel 303 is blown out from the first air outlet area D1, and the airflow in the second channel 304 is blown out from the second air outlet area D2, reducing mutual interference.

[0053] It can be understood that the first air outlet 108 of the humidifying assembly 100 can also have only one, that is, the airflow in the first channel 303 and the second channel 304 is blown out from the same first air outlet 108. However, if the first air outlet 108 of the humidifying assembly 100 is only one, that is, the first air outlet 108 is continuous and uninterrupted, the size and position of the first air outlet 108 correspond to the size and position of the second installation groove 106, and most of the air blown by the first fan 103 is easy to flow out from the end of the first air outlet 108 close to the first fan 103, resulting in only a small part of the air blown by the first fan 103 reaching the other end of the second installation groove 106. The water in the second installation groove 106 evaporates unevenly, the water utilization rate is low, and the humidification efficiency is reduced.

[0054] Referring to Figure 2 As shown, it can be understood that the cover plate 104 is provided with multiple first air outlets 108 arranged at intervals, and the high-humidity air flows out from the multiple first air outlets 108 respectively. Since the multiple first air outlets 108 are arranged at intervals in a direction away from the first fan 103, the air outlet area of a single first air outlet 108 is small, so that the high-humidity air cannot be concentrated to flow out from several first air outlets 108 close to the first fan 103, and more high-humidity air will flow in a direction away from the first fan 103, thereby can take away more water stored in the humidifying material, and also can make more airflow blow out from the micropores 114 to take away the water on the fabric layer 113, thereby improving the humidification efficiency.

[0055] Referring to Figure 4 and Figure 5As shown, in another embodiment, the cover plate 104 comprises a fabric layer 113 which is woven by a plurality of weft threads. The fabric layer 113 is woven by a high-strength material which can be woven, so that it can be manufactured by a weaving process and can also maintain a relatively stable structure and is not easy to deform. Specifically, the material of the fabric layer 113 includes at least one of polyester fiber, aramid fiber, ultra-high molecular weight polyethylene fiber, basalt fiber, polyphenylene sulfide fiber, polyimide fiber, polytetrafluoroethylene fiber, carbon fiber, glass fiber, nylon or polyacrylonitrile fiber, that is, the fabric layer 113 can be woven by a single material or can be woven by a plurality of materials. For example, one weft thread is a polyester fiber material and the other weft thread is a carbon fiber material.

[0056] It can be understood that the fabric layer 113 has a certain water absorption capacity, and the water absorption capacity mainly depends on the type of fiber used by the fabric, the structure of the fabric and the post-processing process. The fiber material used in the fabric is a key factor in determining water absorption. Natural fibers such as cotton, wool, linen and silk generally have good water absorption because they contain a large number of hydrophilic groups in their molecular structure and can absorb water. Certain post-processing processes, such as the addition of water-absorbing agents, can significantly improve the water absorption capacity of the fabric. For example, a special treated polyester-polyamide composite silk fabric can improve its wicking effect and thus enhance its water absorption performance. The surface properties of the fabric, such as roughness and porosity, also affect its water absorption. The rougher and more porous the fabric, the better its water absorption. In some structures, water can also be temporarily stored in the micro-pores 114 under the action of water tension. The fabric layer 113 serves as the first water storage member 115, and the second water storage member 102 is integrally formed with the shell 101 and becomes part of the shell 101.

[0057] Referring to Figure 6 As shown, it can be understood that the humidification channel 302 is only one channel, and the fabric layer 113 and the second water storage member 102 are respectively located on the upper and lower sides of the humidification channel 302, and when the airflow passes through the humidification channel 302, it can simultaneously take away the water in the fabric layer 113 and the second water storage member 102, thereby improving the humidity of the airflow and improving the humidification efficiency. In this embodiment, the height of the humidification assembly 100 does not need to be significantly increased, and the occupied space of the humidification assembly 100 is reduced.

[0058] It can be understood that the first air outlet 108 is an opening on the fabric layer 113, so that the coverage area of the fabric layer 113 can be increased, and thus the overall coverage area of the micro-pores 114 can be increased, which is equivalent to increasing evaporation by using the micro-pores 114 on a large surface area. The large-area micro-pores 114 have the advantage of continuously and uniformly humidifying, so that the humidity distribution is uniform.

[0059] It can be understood that the fabric layer 113 is provided with a plurality of micropores 114, which are gaps between the plurality of weft strips, and the micropores 114 penetrate the cover plate 104 to communicate with the humidification channel 302. The air outlet area of the micropores 114 is much smaller than that of the first air outlet 108. For example, the air outlet area of the micropores 114 ranges from 0.5 square microns to 100 square microns, and the air outlet area of the first air outlet 108 can reach more than 20 square millimeters. A small part of the gas can pass through the micropores 114 to flow outside the humidification assembly 100, and most of the gas flows out of the first air outlet 108 to the outside of the humidification assembly 100, which not only makes the humidification direction of the humidification assembly 100 controllable, but also increases the humidification air outlet area and improves the humidification efficiency.

[0060] It can be understood that when the first fan 103 is powered on, the relatively dry air is sucked into the first fan 103 and accelerated, and then the dry air quickly passes through the lower bottom surface of the fabric layer 113 and the water surface of the second water storage member 102, and the high-humidity air is quickly taken away from the first air outlet 108 to the target space, mixed with the air of the target space, and then the relative humidity of the chamber is increased. A small part of the air passes through the micropores 114, and at the same time, the water adsorbed on the fabric is taken away, which improves the humidification efficiency.

[0061] Referring to Figure 5 It can be understood that the cover plate 104 includes a closed area C and an air outlet area D, and the cover plate 104 is provided with an air inlet 112 through which the first fan 103 sucks in air, and the fabric layer 113 is arranged in the air outlet area D, and the closed area C is located between the first fan 103 and the air outlet area D. The closed area C is not provided with an air outlet, so that the air outlet area D is far away from the air inlet 112, reducing the probability that the humid air is sucked back into the first fan 103 and cannot be fully mixed with the air of the target space.

[0062] In the direction away from the first fan 103, the air outlet area D is divided into a plurality of air outlet units with equal distance at the positions where the first air outlets 108 are arranged. Each of the air outlet units is provided with the first air outlets 108. In the direction away from the first fan 103, the plurality of air outlet units are sequentially defined as the air outlet unit b1, the air outlet unit b2, the air outlet unit b3, the air outlet unit b4, the air outlet unit b5, the air outlet unit b6, and the air outlet unit b7. The air volume of the air outlet unit b2 is greater than that of the air outlet unit b1, the air volume of the air outlet unit b3 is greater than that of the air outlet unit b2, the air volume of the air outlet unit b4 is greater than that of the air outlet unit b3, the air volume of the air outlet unit b5 is greater than that of the air outlet unit b4, the air volume of the air outlet unit b6 is greater than that of the air outlet unit b5, and the air volume of the air outlet unit b7 is greater than that of the air outlet unit b6. Thus, the air volume of the air outlet area D is increased in the direction away from the first fan 103, so that more air flows pass through the end of the liquid surface away from the first fan 103, and the contact area and contact time between the liquid surface and the air flow are increased, so that the humidity of the air flow blown by the humidifying assembly 100 is higher.

[0063] Referring to Figure 5 As shown in FIG. 1, it can be understood that, in some embodiments, the air outlet areas of all the first air outlets 108 are different. The farther away from the first fan 103, the greater the air outlet area of the corresponding first air outlet 108. Specifically, the air outlet area of any one of the first air outlets 108 of the air outlet unit b2 is greater than that of any one of the first air outlets 108 of the air outlet unit b1, the air outlet area of any one of the first air outlets 108 of the air outlet unit b3 is greater than that of any one of the first air outlets 108 of the air outlet unit b2, the air outlet area of any one of the first air outlets 108 of the air outlet unit b4 is greater than that of any one of the first air outlets 108 of the air outlet unit b3, the air outlet area of any one of the first air outlets 108 of the air outlet unit b5 is greater than that of any one of the first air outlets 108 of the air outlet unit b4, the air outlet area of any one of the first air outlets 108 of the air outlet unit b6 is greater than that of any one of the first air outlets 108 of the air outlet unit b5, and the air outlet area of any one of the first air outlets 108 of the air outlet unit b7 is greater than that of any one of the first air outlets 108 of the air outlet unit b6. Thus, the humid air on the entire liquid surface can be more sufficiently taken away.

[0064] It can be understood that in other embodiments, the air outlet area of all first air outlets 108 is the same, and the distance between adjacent two first air outlets 108 gradually decreases in the direction away from the first fan 103, so that the number of first air outlets 108 of the air outlet unit b2 is greater than that of the air outlet unit b1, and the number of first air outlets 108 of the air outlet unit b3 is greater than that of the air outlet unit b2 in the direction away from the first fan 103. For example, the number of first air outlets 108 of the air outlet unit b1 is 1, the number of first air outlets 108 of the air outlet unit b2 is 2, and the number of first air outlets 108 of the air outlet unit b3 is 3. And the distance between adjacent two first air outlets 108 in the direction away from the first fan 103 is L1, L2, L3, L4, L5 in turn, which satisfies: L1>L2>L3>L4>L5. Thus, the airflow blown out from the first fan 103 is less at the air outlet unit b1, and more at the air outlet unit b3, and the airflow blown out from the air outlet unit b3 basically contacts the surface of the length direction of the liquid surface, so that most of the blown-out airflow has high humidity. The airflow blown out from the air outlet unit b1 and the air outlet unit b2 can increase the overall air volume and humidity of the humidifying assembly 100.

[0065] It can be understood that in other embodiments, along the direction away from the first fan 103, the air outlet area D is divided into a plurality of air outlet units with equal distances, and each air outlet unit is provided with a first air outlet 108. The first air outlets 108 of each air outlet unit are arranged in a direction perpendicular to the arrangement direction of the air outlet units, and all the first air outlets 108 can be the same or different. Along the direction away from the first fan 103, the number of first air outlets 108 of each air outlet unit gradually increases. For example, the number of first air outlets 108 of the air outlet unit b1 is 1, the number of first air outlets 108 of the air outlet unit b2 is 2, and the two first air outlets 108 of the air outlet unit b2 are arranged in a direction perpendicular to the arrangement direction of the air outlet units, and the number of first air outlets 108 of the air outlet unit b3 is 3, and the three first air outlets 108 of the air outlet unit b3 are arranged in a direction perpendicular to the arrangement direction of the air outlet units. This embodiment is the same as the embodiment shown in Figure 5 The same as the embodiment shown in Figure 5 In the embodiment shown in the embodiment, all the first air outlets 108 of each air outlet unit are arranged in the arrangement direction of the plurality of air outlet units, and in this embodiment, all the first air outlets 108 of each air outlet unit are arranged in a direction perpendicular to the arrangement direction of the plurality of air outlet units. This embodiment can also achieve that the air volume of the one end away from the first fan 103 is greater than that of the one end close to the first fan 103, thereby improving the humidification efficiency.

[0066] It should be noted that, in order to achieve the air volume of the end away from the first fan 103 is greater than the air volume of the end close to the first fan 103, the air volume of a single first air outlet 108 can be increased in the direction away from the first fan 103, or the number of first air outlets 108 can be increased in the direction away from the first fan 103. In addition to increasing the length of the first air outlet 108 in the direction perpendicular to the arrangement direction of the air outlet unit, the width of the first air outlet 108 in the arrangement direction of the air outlet unit can also be increased in the way of increasing the air volume of a single first air outlet 108. In addition to increasing the number of first air outlets 108 in the linear direction, the number of first air outlets 108 can also be increased in the curved line and the like in the way of increasing the number of first air outlets 108. The above illustrated embodiment is only for convenience of understanding, and is not specifically limited here.

[0067] It should be noted that, Figure 5 The scheme of the cover plate 104 shown can also be applied in the embodiment of Figure 1 .

[0068] Referring to Figure 1 , Figure 3 , Figure 4 and Figure 6 It can be understood that the humidifying assembly 100 includes a connecting air pipe 109, which is used to guide the airflow blown out by the first fan 103 to the outer surface of the first water storage member 115 and the second water storage member 102. The connecting air pipe 109 is provided with a first pipe opening 110 and a second pipe opening 301, the first pipe opening 110 is connected to the outlet of the first fan 103, and the second pipe opening 301 is directed to the humidifying channel 302. The first fan 103 and the connecting air pipe 109 are arranged in the length direction of the shell 101. The outlet size of the first fan 103 is substantially equal to the height of the first mounting groove 105 in the height direction of the shell 101, and is less than the width of the first mounting groove 105 in the width direction of the shell 101, so that the outlet of the first fan 103 is concentrated on one side in the width direction, and a larger air volume is maintained in the height direction. Because the partition 107 is provided between the first mounting groove 105 and the second mounting groove 106, and the second water storage member 102 has a certain height, the height of the first pipe opening 110 is greater than the height of the second pipe opening 301 in the height direction of the shell 101, so as to guide the airflow blown out by the first fan 103 to the humidifying channel 302. In the width direction of the shell 101, the width of the second pipe opening 301 is greater than the width of the first pipe opening 110, so as to increase the contact area of the airflow with the humidifying material of the first water storage member 115 and the second water storage member 102, and improve the humidifying efficiency.

[0069] Referring to Figures 7 to 9As shown, it can be understood that the refrigeration device of the second aspect embodiment of the present application can be a refrigerator, a wine cabinet or the like. The refrigeration device comprises a cabinet body 401, a refrigeration assembly and the humidifying assembly 100 of the first aspect embodiment of the present application. The cabinet body 401 is provided with a storage compartment and an air supply air duct 501 for conveying airflow to the storage compartment. The refrigeration assembly is used to provide a refrigeration environment for the storage compartment and comprises an evaporator 601 and a compressor, which are configured to generate a cooling airflow in a controlled manner and to send the cooling airflow to the storage compartment through the air supply air duct 501. That is, the refrigeration assembly is used to refrigerate the storage compartment. The humidifying assembly 100 is arranged in the cabinet body 401 and is configured to generate a high-humidity airflow in a controlled manner and to convey the high-humidity airflow to the air supply air duct 501 so that the high-humidity airflow flows into the storage compartment together with the cooling airflow. It can be understood that the humidity in the high-humidity airflow is large, which can increase the humidity in the storage compartment.

[0070] Referring to Figure 8 and Figure 9 As shown, it can be understood that the air supply air duct 501 comprises a second air outlet 502 and an air return port 602, which communicate with the storage compartment. The second air outlet 502 is located at the top of the storage compartment, and the air return port 602 is located at the bottom of the storage compartment. The refrigeration device comprises a second fan for promoting air circulation between the storage compartment and the air supply air duct 501. The first air outlet 108 is arranged near the air return port 602. For example, the air return port 602 is located at the rear side of the storage compartment, and the humidifying assembly 100 is also located at the rear side of the storage compartment. The air flowing out of the first air outlet 108 can more easily enter the air return port 602. When the second fan and the humidifying assembly 100 are both in the working state, the high-humidity airflow generated by the humidifying assembly 100 passes through the air return port 602 to the air supply air duct 501 and enters the storage compartment through the second air outlet 502. After being accelerated by the second fan, the high-humidity airflow that flows out of the second air outlet 502 is more fully mixed with the air in the storage compartment, thereby further improving the efficiency of humidification.

[0071] It can be understood that the first fan 103 has a small power and a weak driving ability, and it is difficult to effectively convey the high-humidity airflow generated thereby to the upper region of the storage compartment. The second fan is used to convey the cooling airflow to the storage compartment and has a large power and a strong driving ability. Therefore, the high-humidity airflow generated by the humidifying assembly 100 can be made to flow at a high speed by ingeniously using the air supply of the second fan, so as to be effectively conveyed to the entire space of the storage compartment.

[0072] It should be noted that when the humidifying assembly 100 is in the working state, mainly in the refrigeration stopping stage, even if the evaporator 601 is located in the air supply air duct 501, the evaporator 601 is in a non-working state. The second fan is kept on to accelerate the high-humidity air blown out by the humidifying assembly 100 and interact with the air in the storage compartment, thereby reducing the probability of frosting of the high-humidity airflow due to low temperature.

[0073] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 It can be understood that the cover plate 104 is provided with a water collecting groove 111, which is located below the evaporator 601 and is used to collect and guide the water flow. Specifically, the water collecting groove 111 collects the condensed water / defrosting water into a water flow and drains it to the first water storage member 115 and the second water storage member 102.

[0074] In the embodiment shown in Figure 2 The bottom wall of the water collecting groove 111 is provided with a shunt rib 201 to guide a part of the water flow to the first water storage member 115 and another part of the water flow to the second water storage member 102. The water collecting groove 111 is also provided with a first water inlet 202 and a second water inlet 203, which are located on both sides of the shunt rib 201. The defrosting water can flow back to the first water storage member 115 through the first water inlet 202 and flow back to the second water storage member 102 through the second water inlet 203, respectively, through the shunt of the shunt rib 201. When the refrigeration equipment is defrosting, the defrosting water generated falls into the water collecting groove 111 under the action of gravity, and the defrosting water is reused by flowing along the water collecting groove 111 back to the first water storage member 115 and the second water storage member 102, which can effectively reduce the frequency of water addition by the user.

[0075] It can be understood that the first water inlet 202 and the second water inlet 203 can be in communication with the first air outlet 108, or the first water inlet 202 and the second water inlet 203 can be part of the first air outlet 108.

[0076] In the embodiment shown in Figure 5 When the water flow of the water collecting groove 111 flows to the connection part of the water collecting groove 111 and the woven layer, the water flow will fall from the microporous 114 or the first air outlet 108, thereby supplementing the water storage member.

[0077] The embodiments of the application are described in detail above in combination with the drawings, but the application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the application.
