Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0043] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0044] Reference Figures 1 to 3As shown, the refrigeration equipment of the relevant technology includes a cabinet 101, a refrigeration component, and a humidification component 100. The cabinet 101 has a storage compartment and an air supply duct 201 for delivering airflow to the storage compartment. The refrigeration component provides a cooling environment for the storage compartment and includes an evaporator 301 and a compressor, configured to controllably generate a cooling airflow and direct it through the air supply duct 201 to the storage compartment. In other words, the refrigeration component is used to cool the storage compartment. The humidification component 100 is located in the cabinet 101 and configured to controllably generate a high-humidity airflow and deliver it to the air supply duct 201, so that the high-humidity airflow flows into the storage compartment along with the cooling airflow. It is understood that the high-humidity airflow has a high moisture content, which can increase the humidity inside the storage compartment.

[0045] Reference Figure 2 and Figure 3 As shown, it can be understood that the humidification component 100 is located below the evaporator 301. When the refrigeration equipment is defrosting, the defrosting water produced falls onto the humidification component 100 under the action of gravity, which can replenish the water in the humidification component 100, thereby recovering the defrosting water, effectively reducing the frequency of water addition by the user, and realizing the recycling of defrosting water.

[0046] Specifically, the humidifying component 100 is provided with a water receiving tank 303, which is located below the evaporator 301. The water receiving tank 303 is used to collect and guide water flow. The water receiving tank 303 collects condensate / defrost water and guides it into the interior of the humidifying component 100. The humidifying component 100 is also provided with a water inlet 403, which is located on the bottom wall of the water receiving tank 303. The water flow from the water receiving tank 303 falls into the interior of the humidifying component 100 from the water inlet 403, replenishing the humidifying component 100 with water.

[0047] Understandably, active humidification components typically include a humidifying fan and a water tank. The water tank contains water or humidifying materials such as volcanic rock or non-woven fabric containing moisture. The humidifying fan is located at one end of the water tank and blows air towards the other end, bringing the humidified air from the water tank into the wine cabinet. The humidification component 100 is equipped with an air inlet 401 through which the humidifying fan draws in air. Because the air inlet 401 is located on the top surface of the humidification component 100, condensate from the evaporator 301 may flow into the humidifying fan through the air inlet 401, or the user may accidentally pour water into the air inlet 401 while adding water, causing damage to the humidifying fan.

[0048] The humidification module 501 of this embodiment avoids malfunctions caused by adding water by placing the air inlet 401 on the side of the humidification module 501. See below for further details. Figures 5 to 10 Further explanation of the humidification module 501, humidification component 100 and refrigeration equipment of this utility model embodiment.

[0049] Reference Figure 5 and Figure 6 As shown, the humidification module 501 of this embodiment includes a base 502, a protective cover 503, and a first fan 605. The base 502 has a mounting groove 607, and the first fan 605 is located within the mounting groove 607. The protective cover 503 is connected to the base 502 and covers the top surface of the mounting groove 607. The protective cover 503 has an air inlet 401, which connects to the mounting groove 607 and is located on the side of the base 502. By moving the air inlet 401 from the top surface of the humidification module 501 to the side surface, condensate dripping from the evaporator 301 above is prevented from falling directly into the first fan 605 from the air inlet 401. Even if some water flows down the side from the top surface of the humidification module 501, it is less likely to enter the mounting groove 607 and cause water to enter the first fan 605.

[0050] Reference Figure 7 As shown, the protective cover 503 includes a sidewall located on the side of the base 502, and the sidewall has an air inlet 401. The top wall of the protective cover 503 has no through holes, allowing it to function as a protective barrier and preventing water from flowing into the mounting groove 607. The air inlet 401 is located on the sidewall of the protective cover 503, which makes efficient use of the space between the protective cover 503 and the first fan 605, and also reduces the risk of water entering the first fan 605.

[0051] It should be noted that in some other embodiments, the air inlet 401 may also be located on the side of the base 502, or the air inlet 401 may be defined by the protective cover 503 and the base 502, that is, the protective cover 503 and the base 502 may each be provided with a part of the air inlet 401. In other words, the protective cover 503 and the base 502 may both be provided with a recess, and the two recesses may be combined to form the air inlet 401.

[0052] Reference Figure 6 As shown, it can be understood that the air intake 608 of the first fan 605 faces the top surface of the mounting groove 607. In the axial direction of the air intake 608, the height of the first fan 605 is relatively small, and the humidification module 501 requires less space in the height direction, thus avoiding occupying too much space in the refrigeration equipment.

[0053] Understandably, the humidification module 501 includes an air guide module, which has an air guide channel 704. The air guide channel 704 connects the air inlet 401 and the air intake 608 of the first fan 605, thereby guiding the air at the air inlet 401 to the air intake 608. Since the axial direction of the air inlet 401 is perpendicular or nearly perpendicular to the axial direction of the air intake 608, the airflow changes direction. Without the air guide channel 704, the airflow cannot be concentrated, affecting the air intake efficiency.

[0054] Reference Figure 6 and Figure 7 As shown, it can be understood that the air guiding module includes a fan cover 601, which is used to fix the first fan 605 to the base 502. That is, the first fan 605 is located between the fan cover 601 and the base 502, the fan cover 601 is connected to the base 502, the fan cover 601 and the base 502 are relatively fixed, and the fan cover 601 and the base 502 respectively limit the vertical movement of the first fan 605.

[0055] Reference Figure 6 As shown, the fan cover 601 includes a cover portion, a connecting portion, and a limiting portion. The cover portion is located on the top surface of the first fan 605, thereby limiting the upper part of the first fan 605. The cover portion also has a clearance hole 606, which connects to the air intake 608 of the first fan 605, allowing external air to be normally drawn in by the first fan 605. One end of the connecting portion is connected to the cover portion, and the other end is connected to the base 502. That is, the connecting portion is used to fix the cover portion and the base 502 together. The connecting portion and the base 502 can be connected by screws, clips, or other connection methods. The limiting portion is connected to the cover portion and extends downward from the cover portion. The limiting portion abuts against the side of the first fan 605, thereby limiting the side of the first fan 605.

[0056] Reference Figure 7 As shown, it can be understood that the air guiding module includes a surrounding plate 701, which is located between the protective cover 503 and the fan cover 601. The surrounding plate 701, the protective cover 503, and the fan cover 601 together form an air guiding channel 704. That is, the protective cover 503 and the fan cover 601 define the top and bottom walls of the upper and lower sides of the air guiding channel 704, and the surrounding plate 701 defines the circumferential wall of the air guiding channel 704.

[0057] It should be noted that in some other embodiments, the enclosure 701 may also be provided on the fan cover 601, or the enclosure 701 may be a separate part connected to the fan cover 601 and the protective cover 503.

[0058] Reference Figure 7As shown, the enclosure 701 includes a first part 702 and a second part 703. The first part 702 is disposed along the outer periphery of the air intake 608 away from the air inlet 401, and the second part 703 is disposed along the arrangement direction of the air intake 608 and the air inlet 401. The second part 703 is located on the path between the air intake 608 and the air inlet 401. The second part 703 is connected to the side wall of the protective cover 503 and is composed of two spaced-apart plates, used to guide the air at the air inlet 401 to the air intake 608. The first part 702 and the second part 703 simultaneously prevent other air in the mounting groove 607 from entering the air intake 608, and draw in more dry air from the storage room, which then re-enters the storage room after passing through the humidification component 100, thus improving humidification efficiency. When the first fan 605 is powered on, relatively dry air is drawn into the first fan 605 and accelerated. The dry air quickly passes over the water surface, and the air with high humidity on the water surface is quickly carried into the storage room, where it mixes with the air inside the storage room, thereby increasing the relative humidity inside the storage room.

[0059] Reference Figure 6 As shown, it can be understood that the humidification module 501 includes a temperature and humidity sensor 604, and the fan cover 601 is provided with a mounting part 603. The temperature and humidity sensor 604 is installed in the mounting part 603. The mounting part 603 is located on the lower side of the fan cover 601, which can effectively utilize the space on the lower side of the fan cover 601 and avoid excessive space occupation between the fan cover 601 and the protective cover 503. At the same time, the space on the lower side of the fan cover 601 is relatively large, which facilitates installation and maintenance.

[0060] Reference Figure 6 and Figure 7 As shown, the protective cover 503 has a detection port 402 on its side wall. The mounting part 603 is located on the side of the fan cover 601 near the detection port 402. The fan cover 601 has a through-hole 602. Air in the storage room can reach the temperature and humidity sensor 604 through the detection port 402 and the through-hole 602. The temperature and humidity sensor 604 transmits a signal to the controller based on the detected values, thereby controlling the opening and closing of the humidification component 100. The detection port 402 is located on the side wall of the protective cover 503 to prevent water from entering through the detection port 402 when condensate from the evaporator 301 falls or when the user adds water, thus avoiding damage to the temperature and humidity sensor 604 and the first fan 605.

[0061] It should be noted that in some other embodiments, the detection port 402 may also be disposed on the base 502 and located on the side of the base 502.

[0062] It is understood that in some embodiments, the mounting part 603 includes two positioning parts and two hook parts, which are distributed along the circumferential edge of the communication port 602. The positioning parts are used to maintain the relative position of the temperature and humidity sensor 604 and the communication port 602, and the hook parts are used to fix the temperature and humidity sensor 604 to prevent the temperature and humidity sensor 604 from falling off.

[0063] Reference Figure 9 As shown, it can be understood that the humidification component 100 of this embodiment includes a water storage element 305 and a humidification module 501. The water storage element 305 is used to store water or generate moisture; the humidification module 501 is connected to the water storage element 305, as shown in the figure. Figure 5 As shown, the humidification module 501 is provided with an air outlet 504, which is connected to the mounting groove 607 and faces the water storage component 305.

[0064] Reference Figure 9 As shown, the water storage component 305 includes a tank 801 containing liquid. The top of the tank 801 is open, allowing the liquid inside to evaporate. After the first fan 605 is started, airflow passes through the air outlet 504 and blows towards the tank 801. The liquid inside the tank 801 comes into contact with the airflow from the first fan 605, thereby generating high-humidity gas that enters the target space, increasing the humidity of the target space.

[0065] It should be noted that the water storage component 305 can also include humidifying materials such as volcanic rock or non-woven fabric. That is, the humidifying material can be a porous, multi-layered absorbent material. The diameter and volume of the pores in the porous, multi-layered absorbent material are smaller than the diameter and volume of a normally falling water droplet, so that water droplets cannot flow through the porous, multi-layered absorbent material while allowing airflow. The airflow blown by the first fan 605 enters the second mounting groove 607 from above the partition bar, contacts the humidifying material, and carries away the moisture stored in the humidifying material, thus forming high-humidity air. When the first fan 605 is powered on, relatively dry air is drawn into the first fan 605 and accelerated. The dry air is then quickly blown out from multiple first air outlets 802 and passes over the surface of the humidifying material. The air with high humidity on the surface of the humidifying material is quickly carried to the target space and mixes with the air, thereby increasing the relative humidity of the target space. After the humid air above the humidifying material is carried away, it can quickly absorb moisture from the bottom of the water storage component 305 and evaporate to its upper part (water vapor density is low), thus maintaining a high-humidity state for the air above the humidifying material. The water reservoir 305 can also be a humidifier, such as an ultrasonic humidifier or a steam (thermal evaporation) humidifier. Ultrasonic humidifiers atomize water into micron-sized particles using a high-frequency vibrating ultrasonic transducer (usually a ceramic or metal element), which is then dispersed into the air by a fan. This technology does not generate heat and is therefore called a "cold mist" humidifier. Steam humidifiers heat water to boiling using a heating element, producing steam, which is then released into the air. This type of humidifier is also known as a "hot mist" humidifier.

[0066] Reference Figure 5 and Figure 8 As shown, the protective cover 503 is equipped with a guide groove 505, which is used to guide the water flow to the water storage component 305. By setting the guide groove 505, the liquid on the top surface of the protective cover 503 is guided to the water storage component 305, reducing the flow rate of liquid flowing down the side from the top surface of the protective cover 503, making it less likely for water to enter the mounting groove 607 and cause water to enter the first fan 605. Furthermore, the guide groove 505 guides the water flow to the water storage component 305, which can better replenish the liquid in the water storage component 305 and effectively reduce the frequency of water filling by the user.

[0067] The humidification module 501 includes a cover plate 304, which covers the opening of the tank 801. The cover plate 304 has multiple spaced-apart first air outlets 802, from which highly humid air flows out. When the first fan 605 is powered on, relatively dry air is drawn in and accelerated. The dry air then quickly passes over the liquid surface in the tank 801, while the air with higher humidity on the liquid surface is quickly carried away from the first air outlets 802 on the cover plate 304 and mixed with the air in the storage compartment, thereby increasing the relative humidity of the storage compartment. Because the multiple first air outlets 802 are spaced away from the first fan 605, the outlet area of ​​each individual first air outlet 802 is relatively small. This prevents highly humid air from flowing out from the few first air outlets 802 closest to the first fan 605. Instead, more highly humid air flows away from the first fan 605, thus carrying away more moisture from the stored liquid and improving humidification efficiency.

[0068] It is understandable that the cover plate 304 includes an air outlet area. Along the direction away from the first fan 605, the air outlet area is divided into multiple air outlet units that are equidistant from each other, and each air outlet unit is provided with a first air outlet 802. Along the direction away from the first fan 605, multiple air outlet units are sequentially 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. The air volume of air outlet unit b2 is greater than that of air outlet unit b1, the air volume of air outlet unit b3 is greater than that of air outlet unit b2, the air volume of air outlet unit b4 is greater than that of air outlet unit b3, the air volume of air outlet unit b5 is greater than that of air outlet unit b4, the air volume of air outlet unit b6 is greater than that of air outlet unit b5, and the air volume of air outlet unit b7 is greater than that of air outlet unit b6. This achieves an increase in the air volume of the air outlet area along the direction away from the first fan 605, allowing more airflow to pass through the end of the liquid surface away from the first fan 605, increasing the contact area and contact time between the liquid surface and the airflow, thereby making the airflow blown out by the humidification component 100 more humid.

[0069] Reference Figure 9As shown, it can be understood that in some embodiments, the air outlet area of ​​all the first air outlets 802 is different; the further away from the first fan 605, the larger the air outlet area of ​​the corresponding first air outlet 802. Specifically, the air outlet area of ​​any first air outlet 802 of air outlet unit b2 is larger than that of any first air outlet 802 of air outlet unit b1, the air outlet area of ​​any first air outlet 802 of air outlet unit b3 is larger than that of any first air outlet 802 of air outlet unit b2, the air outlet area of ​​any first air outlet 802 of air outlet unit b4 is larger than that of any first air outlet 802 of air outlet unit b3, and the air outlet area of ​​air outlet unit b5 is larger than that of any first air outlet 802 of air outlet unit b4. The air outlet area of ​​any one of the first air outlets 802 is greater than that of any one of the first air outlets 802 of air outlet unit b4, the air outlet area of ​​any one of the first air outlets 802 of air outlet unit b6 is greater than that of any one of the first air outlets 802 of air outlet unit b5, and the air outlet area of ​​any one of the first air outlets 802 of air outlet unit b7 is greater than that of any one of the first air outlets 802 of air outlet unit b6, to ensure that the humid air on the entire liquid surface is more fully removed.

[0070] It is understood that in some embodiments, all the first air outlets 802 have the same air outlet area. Along the direction away from the first fan 605, the distance between two adjacent first air outlets 802 gradually decreases, such that along the direction away from the first fan 605, the number of first air outlets 802 in air outlet unit b2 is greater than the number in air outlet unit b1, and the number of first air outlets 802 in air outlet unit b3 is greater than the number in air outlet unit b2. For example, air outlet unit b1 has one first air outlet 802, air outlet unit b2 has two first air outlets 802, and air outlet unit b3 has three first air outlets 802. Furthermore, along the direction away from the first fan 605, the distance between two adjacent first air outlets 802 is sequentially divided into L1, L2, L3, L4, and L5, satisfying: L1 > L2 > L3 > L4 > L5. This results in less airflow from the first fan 605 exiting through outlet unit b1 and more airflow exiting through outlet unit b3. The airflow from outlet unit b3 essentially contacts the entire surface of the liquid, resulting in a higher humidity level for most of the airflow. The airflow from outlet units b1 and b2 increases the overall air volume and humidity of the humidification assembly 100.

[0071] It is understood that in some other embodiments, along the direction away from the first fan 605, the air outlet area is divided into multiple equally spaced air outlet units, each air outlet unit having a first air outlet 802. The first air outlet 802 of each air outlet unit is arranged perpendicular to the arrangement direction of the air outlet unit, and all the first air outlets 802 may be the same or different. Along the direction away from the first fan 605, the number of first air outlets 802 in each air outlet unit gradually increases. For example, air outlet unit b1 has one first air outlet 802, air outlet unit b2 has two first air outlets 802, and the two first air outlets 802 of air outlet unit b2 are arranged perpendicular to the arrangement direction of the air outlet unit, air outlet unit b3 has three first air outlets 802, and the three first air outlets 802 of air outlet unit b3 are arranged perpendicular to the arrangement direction of the air outlet unit.

[0072] It should be noted that, in order to achieve a greater airflow at the end furthest from the first fan 605 than at the end closest to the first fan 605, the airflow area of ​​a single first air outlet 802 can be increased along the direction furthest from the first fan 605, or the number of first air outlets 802 can be increased along the same direction. Furthermore, increasing the airflow area of ​​a single first air outlet 802 can be achieved by increasing its length perpendicular to the arrangement direction of the air outlet units, or by increasing its width along the same direction. Increasing the number of first air outlets 802 can be achieved by increasing their number along a straight line, or by increasing their number along curves or other routes. The above illustrated embodiments are for ease of understanding only and are not specifically limited herein.

[0073] Reference Figure 9 As shown, the cover plate 304 is equipped with a water collection trough 303, located below the evaporator 301. The water collection trough 303 is used to collect and guide water flow, and the guide groove 505 communicates with it. Specifically, the water collection trough 303 collects condensate / defrost water and directs it to the tank body 801. A portion of the first air outlet 802 extends into the water collection trough 303. When the water flow from the water collection trough 303 reaches the first air outlet 802 located within it, the water falls from the first air outlet 802, thus replenishing the tank body 801 with water. For example, when the refrigeration equipment is defrosting, the generated defrost water falls into the water collection trough 303 under gravity and returns to the tank body 801 for reuse, effectively reducing the frequency of water refills.

[0074] In some other embodiments, a water inlet 403 may also be provided on the cover plate 304. The water inlet 403 is located on the bottom wall of the water receiving tank 303 and above the tank body 801. The water flow from the water inlet 403 into the tank body 801 replenishes the tank body 801 with water.

[0075] Reference Figure 8 As shown, it can be understood that the depth of the guide groove 505 gradually increases along the direction close to the water storage component 305, and the liquid tends to flow to the lower part, thereby guiding the water flow to flow better toward the water storage component 305.

[0076] Reference Figure 8 As shown, it can be understood that the bottom wall width of the guide groove 505 gradually decreases along the direction close to the water storage component 305, so that the liquid flow rate gradually increases towards the water storage component 305, and can reach the water inlet 403 at the far end in a better and more concentrated manner.

[0077] Reference Figure 10 As shown, it can be understood that the cabinet 101 of the refrigeration equipment in this embodiment of the present invention includes shelves 102. The shelves 102 divide the space inside the cabinet 101 into different storage spaces, making it more convenient to classify and store items. The humidifying component 100 is installed on the shelves 102. (Refer to...) Figure 2 and Figure 3 As shown, the air supply duct 201 includes a second air outlet 202 and a return air outlet 302 connecting the storage room. The second air outlet 202 is located at the top of the storage room, and the return air outlet 302 is located at the bottom of the storage room. The refrigeration equipment includes a second fan for circulating air between the storage room and the air supply duct 201, and a first air outlet 802 is located near the return air outlet 302. When both the second fan and the humidification component 100 are in operation, the high-humidity airflow generated by the humidification component 100 is sent to the air supply duct 201 through the return air outlet 302 and enters the storage room through the second air outlet 202. After secondary acceleration by the second fan, the high-humidity airflow exits from the second air outlet 202 and mixes more thoroughly with the air in the storage room, thereby further improving the humidification efficiency.

[0078] Understandably, the first fan 605 has relatively low power and weak driving capability, making it difficult to effectively deliver the high-humidity airflow it generates to the upper area of ​​the storage compartment. The second fan, however, is used to deliver cooling airflow to the storage compartment; it has higher power and stronger driving capability. Therefore, the second fan can be cleverly used to drive the high-humidity airflow generated by the humidification component 100 at high speed, thereby effectively delivering it to the entire space of the storage compartment.

[0079] It should be noted that when the humidification component 100 is in operation, it is mainly in the stage of stopping cooling. Even if the evaporator 301 is located in the air supply duct 201, the evaporator 301 is not in operation. The second fan is kept on to accelerate the high-humidity air blown out by the humidification component 100 and interact with the indoor air of the storage room, reducing the probability of high-humidity airflow frosting due to low temperature.

[0080] Reference Figure 10 As shown, it can be understood that the cabinet 101 includes a back panel 901, a guide groove 505 and a water receiving groove 303 located on the rear side of the back panel 901, an air inlet 401 facing the front side of the back panel 901, the air inlet 401 being higher than the top surface of the shelf 102, and the gap between the back panel 901 and the humidification component 100 forming a return air inlet 302.

[0081] It should be noted that in some other embodiments, the humidifying component 100 of this utility model can also be an integrated component. For example, the humidifying component 100 includes a housing, a water storage component 305, and a first fan 605. A first mounting groove 607 and a second mounting groove 607 are provided inside the housing. A partition strip is provided between the first mounting groove 607 and the second mounting groove 607, located at the bottom of the first mounting groove 607 and the second mounting groove 607, so that the bottoms of the first mounting groove 607 and the second mounting groove 607 are not connected, but the tops of the first mounting groove 607 and the second mounting groove 607 can be connected. The first fan 605 is disposed in the first mounting groove 607, and the water storage component 305 is disposed in the second mounting groove 607.

[0082] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
