[0018] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. 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.

[0020] In the description of the present invention, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0021] 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.

[0022] In low temperature environments, the humidity inside refrigeration equipment tends to drop to a low level, causing the moisture on the surface of items to evaporate, causing the items to dry out and deteriorate in quality. The humidification component releases water vapor or atomized water droplets to increase the humidity inside the equipment, thereby keeping the items moist and preventing them from being damaged by drying out.

[0023] Take the wine cabinet as an example. The humidification component in the wine cabinet is designed to maintain a suitable humidity environment in the wine cabinet. Red wine in particular needs to be stored at a constant humidity to prevent the cork from drying out and the wine from evaporating, thus maintaining the taste and quality of the wine. In simple terms, the humidification component of the wine cabinet ensures that the wine will not change its taste due to the dry environment.

[0024] The active humidification type humidification component generally includes a humidification fan and a water storage tank. Water or humidification materials such as volcanic rocks and non-woven fabrics containing water are placed in the water storage tank. The humidification fan is located at one end of the water storage tank and blows air toward the other end of the water storage tank. The high-humidity air in the water storage tank is brought to the wine cabinet through the humidification fan. The long strip water storage tank design lengthens the length of the water storage tank, making the water surface area larger, which helps to increase the evaporation rate of water. During the humidification process, more water molecules can be exposed to the air, thereby accelerating evaporation.

[0025] However, since wine cabinets of different widths require humidification components of different sizes, most humidification components in related technologies are only applicable to the structure of a certain model and cannot be used for multiple models. As a module with a fixed size, the humidification component needs to be replaced in its entirety in order to be applied to wine cabinets of different widths. In addition, the overall size of the humidification component is relatively large, which has a significant impact on the overall appearance of the refrigeration equipment. The humidification component is installed inside the refrigeration equipment, and the overall size of the humidification component is relatively large, which also increases the difficulty of operation.

[0026] Refer to the following Figures 1 to 11 It is described how the refrigeration device according to the embodiment of the present invention solves the above problems.

[0027] Figure 1 and Fig.10 The refrigeration device of an embodiment of the present invention is shown. The refrigeration device can be a refrigerator, a wine cabinet and other products. The refrigeration device includes a cabinet 901, a refrigeration component and a humidification module 101. The cabinet 901 is provided with a storage room and an air supply duct 1001 for conveying airflow to the storage room. The refrigeration component is used to provide a refrigeration environment for the storage room. The refrigeration component includes an evaporator 1101 and a compressor, which are configured to generate a cooling airflow in a controlled manner and promote the cooling airflow to be conveyed to the storage room through the air supply duct 1001. In other words, the refrigeration component is used to cool the storage room. The humidification module 101 is arranged in the cabinet 901 and is configured to generate an airflow in a controlled manner.

[0028] Reference Figure 1As shown, it can be understood that the cabinet 901 is provided with an opening 104, the opening 104 is connected to the storage room, the trough 201 and the humidification module 101 are located in the storage room, and the trough 201 and the opening 104 are located on opposite sides of the storage room, the user takes and puts items from the opening 104, the humidification module 101 is away from the user, the trough 201 and the humidification module 101 are located at the deepest part of the cabinet 901, and the humidification module 101 is small in size to reduce the presence of the appearance as much as possible without destroying the original interior structure of the refrigeration equipment.

[0029] Reference Figure 1 As shown, it can be understood that the cabinet 901 includes a layer plate 102, which divides the space in the cabinet 901 to form different storage spaces, making it more convenient to store by classification, and the tank 201 and the humidification module 101 are installed on the layer plate 102. Figure 2 and Figure 3 As shown, a trough 201 is provided on the layer plate 102, that is, when the cabinet 901 is manufactured, a trough 201 is opened on the layer plate 102, and the trough 201 can store water or place humidification materials. The trough 201 is formed into different sizes according to the layer plates 102 of different sizes, and the humidification module 101 can be made into a uniform size, which improves the versatility of the humidification module 101. The humidification module 101 has many parts and a complex structure. Making it into a universal module can reduce the cost of the refrigeration equipment. The trough 201 has a simple structure and is easy to manufacture. Changing the size of the trough 201 will not significantly increase the cost. The trough body 201 and the humidification module 101 constitute the humidification component 100. In this embodiment, the trough body 201 and the humidification module 101 of the humidification component 100 are separately arranged, so that the trough body 201 and the shelf 102 of the cabinet 901 are integrally formed. The humidification module 101 is an independent and universal module, which not only improves the versatility, but also makes the overall appearance of the refrigeration equipment more unified. The size of the humidification module 101 is smaller than that of the humidification component 100, and the difficulty of installation and disassembly is lower.

[0030] Reference Figure 3 As shown, it can be understood that the installation position of the humidification module 101 is reserved on the layer plate 102, that is, the layer plate 102 is provided with an installation position, and the humidification module 101 is installed at the installation position. The layer plate 102 is provided with a groove, a part of the groove forms a groove body 201, which can store liquid, and the other part forms an installation position for placing the humidification module 101, which is convenient for both manufacturing and installation.

[0031] It should be noted that the humidification module 101 and the tank body 201 may also be arranged in two independent recesses.

[0032] Reference Figure 2 , Figure 3 and Figure 5As shown, it can be understood that liquid is stored in the tank body 201, and the top of the tank body 201 is open, so that the liquid in the tank body 201 can emit moisture. The humidification module 101 includes a base 501 and a first fan 502. The base 501 is provided with a mounting groove 503 and an air supply port 610. The first fan 502 is located in the mounting groove 503. The air supply port 610 is connected to the mounting groove 503 and faces the tank body 201. After the first fan 502 is started, the air flow passes through the air supply port 610 and blows toward the tank body 201. The liquid in the tank body 201 contacts the air flow blown out by the first fan 502, thereby generating high-humidity gas that enters the storage compartment and increases the humidity of the storage compartment.

[0033] It is understandable that the humidification module 101 is detachably connected to the cabinet 901, and the humidification module 101 can be installed in models of different widths as a separate universal module, and the tank 201 can be fixed in the cabinet 901. Compared with the prior art, which requires the replacement of the entire humidification assembly 100, this embodiment only requires the corresponding modification of the size of the tank 201 when manufacturing the layer plate 102, thereby reducing the cost. The humidification module 101, as an independent module, can be used in models of different widths, thereby improving the versatility.

[0034] Reference Figure 3 and Figure 4 As shown, it can be understood that the tank body 201 is provided with an overflow port 304, the height of the overflow port 304 is higher than the height of the bottom wall of the tank body 201, and the distance between the overflow port 304 and the bottom wall of the tank body 201 is the water storage height of the tank body 201. The height of the overflow port 304 is lower than the height of the air supply port 610, which can prevent the liquid in the tank body 201 from entering the humidification module 101 from the air supply port 610 to damage the components such as the fan. When the liquid level in the tank body 201 reaches the height of the overflow port 304, the excess liquid is discharged from the overflow port 304.

[0035] Reference Figure 4 As shown, it can be understood that the bottom wall of the tank body 201 is provided with a boss 404, and the overflow port 304 is provided on the top surface of the boss 404. For example, the height of the top surface of the boss 404 is 10 mm to 20 mm lower than the height of the lowest point of the air outlet 610. When the difference between the height of the top surface of the boss 404 and the height of the lowest point of the air outlet 610 is less than 10 mm, the sloshing of the liquid can easily cause part of the liquid to enter the humidification module 101, causing damage to the components. When the difference between the height of the top surface of the boss 404 and the height of the lowest point of the air outlet 610 is greater than 20 mm, the liquid capacity that can be stored in the tank body 201 is small, which is not conducive to humidification.

[0036] Reference Figure 2The refrigeration device includes a cover plate 103, which is arranged at the notch of the tank body 201. The cover plate 103 is provided with a plurality of first air outlets 105 arranged at intervals, and high-humidity air flows out from the plurality of first air outlets 105 respectively. When the first fan 502 is powered on, relatively dry air is sucked into the first fan 502 for acceleration, and the dry air quickly passes through the liquid surface in the tank body 201, and the air with high humidity on the liquid surface is quickly taken away from the first air outlet 105 on the cover plate 103 to the storage room to mix with the air, thereby increasing the relative humidity of the storage room. Since the plurality of first air outlets 105 are arranged at intervals in a direction away from the first fan 502, the air outlet area of ​​a single first air outlet 105 is small, so that the high-humidity air cannot be concentrated and flowed out from the first air outlets 105 close to the first fan 502, and more high-humidity air will flow in a direction away from the first fan 502, thereby taking away more moisture stored in the liquid, thereby improving the humidification efficiency.

[0037] It should be noted that the refrigeration equipment may also include humidifying materials such as volcanic rocks and non-woven fabrics, that is, the humidifying material may be a porous dense structure water-absorbing material, and the diameter and volume of the holes on the porous dense structure water-absorbing material are smaller than the diameter and volume of the normal dripping water droplets, so that the water droplets cannot flow through the porous dense structure water-absorbing material, and at the same time, the air flow can pass through. The airflow blown out by the first fan 502 enters the second installation groove 503 from the top of the partition bar, contacts the humidifying material and takes away the moisture stored in the humidifying material, thereby forming high-humidity air. The first fan 502 is powered on and works, and after the relatively dry air is sucked into the first fan 502 and accelerated, the dry air quickly passes through the surface of the humidifying material and blows out from the first air outlet 105, and the air with high humidity on the surface of the humidifying material is quickly taken away to the storage room and mixed with the air, thereby increasing the relative humidity of the storage room. After the humid air above the humidifying material is taken away, it can quickly absorb the moisture at the bottom of the tank body 201 and evaporate to the top thereof (the water vapor density is small), so that the air above the humidifying material remains in a high-humidity state.

[0038] It can be understood that the cover plate 103 includes an air outlet area, and along the direction away from the first fan 502, the air outlet area is divided into a plurality of air outlet units with equal distances, and each air outlet unit is provided with a first air outlet 105. Along the direction away from the first fan 502, multiple air outlet units are defined as air outlet unit b1, air outlet unit b2, air outlet unit b3, air outlet unit b4, air outlet unit b5, air outlet unit b6, and air outlet unit b7 in sequence. The air outlet volume of air outlet unit b2 is greater than the air outlet volume of air outlet unit b1, the air outlet volume of air outlet unit b3 is greater than the air outlet volume of air outlet unit b2, the air outlet volume of air outlet unit b4 is greater than the air outlet volume of air outlet unit b3, the air outlet volume of air outlet unit b5 is greater than the air outlet volume of air outlet unit b4, the air outlet volume of air outlet unit b6 is greater than the air outlet volume of air outlet unit b5, and the air outlet volume of air outlet unit b7 is greater than the air outlet volume of air outlet unit b6, so that the air outlet volume of the air outlet area increases along the direction away from the first fan 502, allowing more airflow to pass through the end of the liquid surface away from the first fan 502, increasing the contact area and contact time between the liquid surface and the airflow, so that the humidity of the airflow blown out by the humidification component 100 is higher.

[0039] Reference Figure 3 As shown, it can be understood that, in some embodiments, the air outlet areas of all the first air outlets 105 are different, and the farther away from the first fan 502, the larger the air outlet area of ​​the corresponding first air outlet 105. Specifically, the air outlet area of ​​any first air outlet 105 of the air outlet unit b2 is larger than the air outlet area of ​​any first air outlet 105 of the air outlet unit b1, the air outlet area of ​​any first air outlet 105 of the air outlet unit b3 is larger than the air outlet area of ​​any first air outlet 105 of the air outlet unit b2, the air outlet area of ​​any first air outlet 105 of the air outlet unit b4 is larger than the air outlet area of ​​any first air outlet 105 of the air outlet unit b3, and the air outlet area of ​​any first air outlet 105 of the air outlet unit b5 is larger than the air outlet area of ​​any first air outlet 105 of the air outlet unit b6. The air outlet area of ​​any first air outlet 105 of the air outlet unit b4 is larger than the air outlet area of ​​any first air outlet 105 of the air outlet unit b4, the air outlet area of ​​any first air outlet 105 of the air outlet unit b6 is larger than the air outlet area of ​​any first air outlet 105 of the air outlet unit b5, and the air outlet area of ​​any first air outlet 105 of the air outlet unit b7 is larger than the air outlet area of ​​any first air outlet 105 of the air outlet unit b6, thereby ensuring that the humid air on the entire liquid surface is more fully taken away.

[0040] It can be understood that in other embodiments, the air outlet areas of all the first air outlets 105 are the same, and the distance between two adjacent first air outlets 105 gradually decreases in the direction away from the first fan 502, so that in the direction away from the first fan 502, the number of first air outlets 105 of the air outlet unit b2 is greater than the number of first air outlets 105 of the air outlet unit b1, and the number of first air outlets 105 of the air outlet unit b3 is greater than the number of first air outlets 105 of the air outlet unit b2. For example, the number of first air outlets 105 of the air outlet unit b1 is 1, the number of first air outlets 105 of the air outlet unit b2 is 2, and the number of first air outlets 105 of the air outlet unit b3 is 3. And in the direction away from the first fan 502, the distances between two adjacent first air outlets 105 are L1, L2, L3, L4, and L5, respectively, satisfying: L1>L2>L3>L4>L5. As a result, the airflow blown out from the first fan 502 is less blown out from the air outlet unit b1, and more blown out from the air outlet unit b3. The airflow blown out from the air outlet unit b3 basically contacts the entire surface of the liquid surface, so that most of the blown airflow has a 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 humidification component 100.

[0041] It can be understood that in some other embodiments, along the direction away from the first fan 502, the air outlet area is divided into a plurality of air outlet units with equal distances, and each air outlet unit is provided with a first air outlet 105. The first air outlet 105 of each air outlet unit is arranged along a direction perpendicular to the arrangement direction of the air outlet unit, and all the first air outlets 105 may be the same or different. Along the direction away from the first fan 502, the number of first air outlets 105 of each air outlet unit gradually increases. For example, the number of first air outlets 105 of the air outlet unit b1 is 1, the number of first air outlets 105 of the air outlet unit b2 is 2, and the two first air outlets 105 of the air outlet unit b2 are arranged along a direction perpendicular to the arrangement direction of the air outlet units, the number of first air outlets 105 of the air outlet unit b3 is 3, and the three first air outlets 105 of the air outlet unit b3 are arranged along a direction perpendicular to the arrangement direction of the air outlet units.

[0042] It should be noted that, in order to achieve that the air volume at the end away from the first fan 502 is greater than the air volume at the end close to the first fan 502, the air outlet area of ​​a single first air outlet 105 can be increased in the direction away from the first fan 502, or the number of first air outlets 105 can be increased in the direction away from the first fan 502. In addition to increasing the length of the first air outlet 105 along the direction perpendicular to the arrangement of the air outlet units, the width of the first air outlet 105 can also be increased along the arrangement direction of the air outlet units. In addition to increasing the number of first air outlets 105 along a straight line, the number of first air outlets 105 can also be increased along a curve or other lines. The above illustrated embodiments are only for easy understanding and are not specifically limited here.

[0043] It is understandable that the cover plate 103 includes a closed area, an air inlet 106 is provided on the cover plate 103, the first fan 502 sucks air through the air inlet 106, and the closed area is located between the first fan 502 and the air outlet area. No air outlet is provided in the closed area, so that the air outlet area is far away from the air inlet 106, reducing the probability that the humid air is sucked back to the first fan 502 and cannot be fully mixed with the air in the storage compartment.

[0044] Reference Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, it can be understood that the humidification module 101 includes an air guide portion 301, and the air guide portion 301 is used to guide the airflow blown out by the first fan 502 to the outer surface of the liquid in the tank body 201. The air guide portion 301 is provided with a first pipe opening 302 and a second pipe opening 303, the first pipe opening 302 is connected to the outlet of the first fan 502, and the second pipe opening 303 is connected to the air supply port 610, and the first fan 502, the air guide portion 301 and the tank body 201 are arranged along the length direction of the shell.

[0045] Reference Figure 8 As shown, in some embodiments, the air guide portion 301 is integrally formed with the base 501. In the height direction of the base 501, the height of the first pipe opening 302 is greater than the height of the second pipe opening 303, and the airflow blown out by the first fan 502 is guided to the gap between the cover plate 103 and the tank body 201. In the width direction of the base 501, the width of the second pipe opening 303 is greater than the width of the first pipe opening 302, thereby increasing the contact area between the airflow and the liquid surface of the tank body 201 and improving the humidification efficiency.

[0046] Reference Figure 5 and Figure 6As shown, it can be understood that the refrigeration equipment of another embodiment of the present invention includes an air distribution duct 401, which is connected to the first fan 502, and the air distribution duct 401 is provided with a plurality of third air outlets 402, and all the third air outlets 402 face the trough body 201, that is, the conveying airflow generated by the first fan 502 is divided into a plurality of branch airflows through all the third air outlets 402 and then passes through the trough body 201.

[0047] Reference Figure 5 As shown, it can be understood that, among any two third air outlets 402, the air outlet area of ​​the third air outlet 402 far away from the first fan 502 is greater than the air outlet area of ​​the third air outlet 402 close to the first fan 502. That is, the air outlet areas of all the third air outlets 402 are different, and the trend of change is increasing in the direction away from the first fan 502. Among them, the wind pressure in the air distribution duct 401 is also uneven, the closer the wind pressure is to the first fan 502, the greater the wind pressure is, and the farther away from the first fan 502, the smaller the wind pressure is. The wind pressure is proportional to the square of the wind speed, which can be specifically expressed by the Bernoulli equation. Specifically, the air outlet area of ​​the third air outlet 402 at one end of the air distribution duct 401 close to the first fan 502 is the smallest, but its wind speed is the largest. The air outlet area of ​​the third air outlet 402 at one end of the air distribution duct 401 far away from the first fan 502 is the largest, but the wind speed is the smallest. In this way, the difference in air volume of each third air outlet 402 is small, so that the air flow blown out by the fan can maintain a relatively uniform contact with the liquid surface of the entire tank body 201, and the humidity distribution of the air outlet of the humidification component 100 is more uniform.

[0048] Reference Figure 5 and Figure 6 As shown, it can be understood that the refrigeration device includes an air guide portion 301, and the air guide portion 301 is an independent structure. In this embodiment, the air guide portion 301 is used to guide the airflow blown out by the first fan 502 to the air distribution duct 401. The air guide portion 301 is provided with a first pipe opening 302 and a second pipe opening 303, the first pipe opening 302 is connected to the outlet of the first fan 502, and the second pipe opening 303 is connected to the air distribution duct 401. The first fan 502, the air guide portion 301 and the air distribution duct 401 are arranged along the length direction of the base 501, and the air distribution duct 401 is arranged on one side of the width direction of the base 501 and is located above the tank body 201. In the height direction of the base 501, the height of the first pipe opening 302 is greater than the height of the second pipe opening 303, and the airflow blown out by the first fan 502 is guided to the air distribution duct 401. In the width direction of the base 501, the width of the second pipe opening 303 is smaller than the width of the first pipe opening 302, thereby reducing the occupied space of the air distribution duct 401. The airflow blown out from the air distribution duct 401 can contact a larger area of ​​humidification material, thereby improving the humidification efficiency.

[0049] It should be noted that, in some other embodiments, the distance between two adjacent third air outlets 402 gradually decreases in the direction away from the first fan 502, so that the purpose of making the air volume of each length unit of the air distribution duct 401 uniform can be achieved by gradually increasing the number of third air outlets 402 in the direction away from the first fan 502. In addition, the way to increase the air outlet area of ​​a single third air outlet 402 is to increase the width of the third air outlet 402 along the length direction perpendicular to the air distribution duct 401, and the length of the third air outlet 402 can also be increased along the length direction of the air distribution duct 401. The way to increase the number of first air outlets 105 is to increase the number of third air outlets 402 along the length direction of the air distribution duct 401, and the number of third air outlets 402 can also be increased along the width of the third air outlet 402, which is not specifically limited here.

[0050] Reference Figure 5 and Figure 6 As shown, it can be understood that a plurality of equally spaced partitions 403 are further provided in the housing, and the plurality of partitions 403 are arranged along the length direction of the air distribution duct 401, that is, arranged in a direction away from the first fan 502. One or more third air outlets 402 are provided between every two partitions 403, so that an independent humidification unit is formed between every two partitions 403. The function of the partition 403 is to prevent the humidification units from being easily affected or interfered with each other, thereby ensuring the humidification uniformity of the humidification assembly 100 at each position.

[0051] It is understandable that in order to ensure that the humidity of each humidification unit is approximately equal, this can be achieved by increasing the air outlet area of ​​the third air outlet 402 or increasing the number of the third air outlet 402 in the direction away from the first fan 502. For example, when the number of third air outlets 402 contained in all humidification units is equal, the air outlet area of ​​the third air outlet 402 of the humidification unit close to the first fan 502 is smaller than the air outlet area of ​​the third air outlet 402 of the humidification unit away from the first fan 502. When the air outlet area of ​​a single third air outlet 402 contained in all humidification units is equal, the number of third air outlets 402 of the humidification unit close to the first fan 502 is smaller than the number of third air outlets 402 of the humidification unit away from the first fan 502.

[0052] The humidification module 101 includes a fan cover 601, which is used to fix the first fan 502 to the base 501. That is, the first fan 502 is located between the fan cover 601 and the base 501, the fan cover 601 is connected to the base 501, the fan cover 601 and the base 501 are relatively fixed, and the fan cover 601 and the base 501 respectively limit the first fan 502 in the up and down directions.

[0053] Reference Figure 7As shown, it can be understood that the fan cover 601 includes a cover portion 602, a connecting portion 603 and a limiting portion 604. The cover portion 602 is located on the top surface of the first fan 502 so as to limit the upper part of the first fan 502. The cover portion 602 is also provided with an avoidance hole 605, which is connected to the air inlet 606 of the first fan 502, so that the external gas can be normally sucked into the first fan 502. One end of the connecting portion 603 is connected to the cover portion 602, and the other end is connected to the base 501, that is, the connecting portion 603 is used to fix the cover portion 602 and the base 501. The connecting portion 603 and the base 501 can be connected by screws, buckles and other connection methods. The limiting portion 604 is connected to the cover portion 602, and the limiting portion 604 extends downward from the cover portion 602. The limiting portion 604 abuts against the side of the first fan 502 to limit the side of the first fan 502.

[0054] Reference Figure 7 As shown, it can be understood that the humidification module 101 includes a protective cover 607 and a temperature and humidity sensor 608, the protective cover 607 is connected to the base 501, and the protective cover 607 is provided with an air inlet 106, the air inlet 106 is located above the first fan 502, and is connected to the air inlet 606 of the first fan 502. Fig. 9 As shown, it can be understood that the protective cover 607 is provided with a detection port 609 and a mounting portion, the detection port 609 is connected to the outside of the humidification module 101, and the temperature and humidity sensor 608 is located at the detection port 609 and mounted on the mounting portion, so that the temperature and humidity sensor 608 can detect the temperature and humidity of the storage compartment. The mounting portion includes two positioning portions 801 and two hook portions 802, and the two positioning portions 801 and the two hook portions 802 are distributed along the circumferential edge of the detection port 609. The positioning portion 801 is used to maintain the relative position of the temperature and humidity sensor 608 and the detection port 609, and the hook portion 802 is used to fix the temperature and humidity sensor 608 to prevent the temperature and humidity sensor 608 from falling off.

[0055] Reference Fig.10 and Fig.11 As shown, it can be understood that the air supply duct 1001 includes a second air outlet 1002 and a return air outlet 1102 connected to the storage compartment, the second air outlet 1002 is located at the top of the storage compartment, and the return air outlet 1102 is located at the bottom of the storage compartment. The refrigeration device includes a second fan for promoting air circulation between the storage compartment and the air supply duct 1001, and the first air outlet 105 is located near the return air outlet 1102. When the second fan and the humidification module 101 are both in working state, the high humidity airflow generated by the humidification component 100 is sent to the air supply duct 1001 through the return air outlet 1102, and enters the storage compartment through the second air outlet 1002. After the secondary acceleration of the second fan, the high humidity airflow comes out of the second air outlet 1002 and mixes more fully with the air in the storage compartment, thereby further improving the efficiency of humidification.

[0056] It is understandable that the first fan 502 has a relatively small power and a relatively weak driving capability, and it is difficult to effectively deliver the high-humidity airflow generated by it to the upper area of ​​the storage compartment. The second fan is used to deliver cooling airflow to the storage compartment, and has a relatively large power and a relatively strong driving capability. Therefore, the second fan can be cleverly used to deliver air to cause the high-humidity airflow generated by the humidification assembly 100 to flow at a high speed, thereby effectively delivering it to the entire space of the storage compartment.

[0057] It should be noted that when the humidifying component 100 is in working state, mainly in the stage of stopping cooling, even if the evaporator 1101 is located in the air supply duct 1001, the evaporator 1101 is in a non-working state, and the second fan is kept turned on to accelerate the high-humidity air blown out by the humidifying component 100 and interact with the indoor air of the storage room, thereby reducing the probability of frost of the high-humidity airflow due to low temperature.

[0058] It is understandable that the high humidity airflow is delivered to the air supply duct 1001 so that the high humidity airflow flows into the storage compartment along with the cooling airflow. It is understandable that the moisture in the high humidity airflow is relatively large, which can increase the humidity in the storage compartment.

[0059] Reference Figure 2 , Figure 3 and Figure 6 As shown, it can be understood that the cover plate 103 is provided with a water receiving groove 107, and the water receiving groove 107 is located below the evaporator 1101. The water receiving groove 107 is located below the evaporator 1101 and is used to collect and guide water flow. Specifically, the water receiving groove 107 collects the collected condensed water / defrosting water into a water flow and guides it to the tank body 201. Part of the first air outlet 105 extends to the water receiving groove 107. When the water flow of the water receiving groove 107 flows to the first air outlet 105 located in the water receiving groove 107, the water flow will fall from the first air outlet 105, thereby replenishing water for the tank body 201. For example, when the refrigeration equipment is defrosting, the defrosting water generated falls into the water receiving groove 107 under the action of gravity, and the defrosting water returns to the tank body 201 along the water receiving groove 107 for reuse, which can effectively reduce the frequency of users adding water.

[0060] In some other embodiments, a water inlet 108 may also be provided on the cover plate 103 , and the water inlet 108 is located on the bottom wall of the water receiving trough 107 , and the water inlet 108 is located above the trough body 201 , and the water flow of the water receiving trough 107 falls into the trough body 201 from the water inlet 108 to replenish water for the trough body 201 .

[0061] By setting a water receiving tank 107 under the evaporator 1101, the condensed water generated by the evaporator 1101 is effectively collected and guided, and then the water resources are used to evaporate through the humidification material, so as to achieve the purpose of humidifying the air. This design not only improves the utilization rate of water resources, but also reduces the frequency of users adding water.

[0062] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
