The use of "first" and "second" in the description is merely for 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.

[0035] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0036] In low-temperature environments, the humidity inside refrigeration equipment often drops to very low levels, causing moisture to evaporate from the surface of items, leading to dryness and a decline in quality. Humidification components increase the humidity inside the equipment by releasing water vapor or atomizing water droplets, thereby keeping items moist and preventing them from being damaged by dryness.

[0037] Taking wine cabinets as an example, the humidifier in a wine cabinet is designed to maintain a suitable humidity environment inside. Red wine, in particular, needs to be stored in a constant humidity level to prevent the cork from drying out and the wine from evaporating, thus preserving the wine's taste and quality. Simply put, the humidifier in a wine cabinet ensures that fine wines don't spoil due to an overly dry environment.

[0038] Active humidification systems typically consist of 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 tank into the wine cabinet. The elongated design of the water tank increases its length, resulting in a larger water surface area, which helps to increase the evaporation rate. During humidification, more water molecules are exposed to the air, thus accelerating evaporation.

[0039] Reference Figure 1 and Figure 5As shown, the refrigeration equipment includes a cabinet 101, a refrigeration component, and a humidification component 103. The cabinet 101 has a storage compartment 102 and an air duct 501 for supplying airflow to the storage compartment 102. The refrigeration component provides a cooling environment for the storage compartment 102 and is configured to generate a controlled cooling airflow, which is then delivered to the storage compartment 102 through the air duct 501. In other words, the refrigeration component is used to cool the storage compartment 102. The humidification component 103 is located in the cabinet 101 and is configured to generate a controlled high-humidity airflow, which is then delivered to the storage compartment 102. It is understood that the high-humidity airflow contains a high level of moisture, thus increasing the humidity within the storage compartment 102.

[0040] It is understood that the refrigeration equipment in the embodiments of the present invention may specifically be a refrigerator, wine cabinet, or other similar products.

[0041] Reference Figure 4 As shown, the humidifying component 103 includes a water storage unit 201 for storing water. For example, the water storage unit 201 is a water tank containing liquid, with the top of the tank open. Water evaporation increases the humidity inside the refrigeration equipment. The humidifying component 103 also includes a fan 202 that blows air towards the water storage unit 201; that is, the fan 202 has an air outlet facing the water storage unit 201. When the fan 202 is powered on, relatively dry air is drawn in, accelerated, and reaches above the water storage unit 201. The dry air quickly passes over the liquid surface inside the water storage unit 201, and the air with higher humidity on the liquid surface is quickly carried to the storage chamber 102 to mix with the air, thereby increasing the relative humidity of the storage chamber 102.

[0042] Reference Figure 4 As shown, the humidifying component 103 also includes a housing 203, which includes a base 204. The base 204 has a first mounting groove 205 and a second mounting groove 206. A partition strip is provided between the first mounting groove 205 and the second mounting groove 206, located at the bottom of both grooves, preventing communication between their bottoms and allowing communication between their tops. A fan 202 is disposed in the first mounting groove 205, and a water storage component 201 is disposed in the second mounting groove 206. The water storage component 201 may include a water tank, which is integrally formed with the housing 203, becoming part of the housing 203. Alternatively, the water tank can be disposed separately in the second mounting groove 206, meaning it can be an independent component.

[0043] It should be noted that the water storage component 201 may also include humidifying material, such as volcanic rock or non-woven fabric. In other words, the humidifying material can be a porous, multi-layered absorbent material. The diameter and volume of the pores in this material are smaller than the diameter and volume of a normal water droplet, preventing water droplets from flowing through while allowing airflow. After the fan 202 starts, the airflow blown by the fan enters the second mounting groove 206 from above the partition bar. Dry air passes over the surface of the humidifying material, contacting it and carrying away the stored moisture, thus creating high-humidity air. This high-humidity air reaches the storage chamber 102 and mixes with the surrounding air, increasing the relative humidity of the chamber. The humid air above the humidifying material, after being carried away, can quickly absorb moisture from the bottom of the material and evaporate it upwards (due to the low density of water vapor), thus maintaining a high-humidity environment above the material.

[0044] Reference Figure 4 As shown, it can be understood that the housing 203 also includes a cover plate 207, which is connected to the base 204 and located above the first mounting groove 205 and the second mounting groove 206. There is a gap between the cover plate 207 and the liquid surface of the humidifying material or water box to form a humidification channel, which is used to guide the flow direction of the high-humidity gas.

[0045] It is understood that in some other embodiments, the housing 203 may also be formed by a combination of a base plate and a cover, that is, the water storage component 201 and the fan 202 are installed on the base plate, the cover is placed on the outer periphery and top surface of the water storage component 201 and the fan 202, and then connected and fixed to the base plate, and the bottom surface of the water storage component 201 and the fan 202 is sealed by the base plate, thereby completing the installation and protection of the water storage component 201 and the fan 202.

[0046] Reference Figure 1 As shown, the cabinet 101 includes shelves 104 arranged horizontally, which divide the space inside the cabinet 101 into different storage spaces for easier categorization. A humidifying component 103 is installed on the shelf 104. The humidifying component 103 requires regular maintenance and cleaning to ensure its normal operation and extend its service life. The shelf 104's central position facilitates regular inspection and maintenance of the humidifying component 103.

[0047] In related technologies, the cover plate 207 is provided with multiple spaced air vents, from which highly humid air flows out separately. It is understandable that placing the air vents on the cover plate 207, while the humidification component 103 is entirely mounted on the shelf 104, may present some problems, such as the risk of the air vents being blocked. For example, items such as wine bottles may be placed on the shelf 104, and if the humidification component 103 is placed near these items, or if items fall onto the shelf 104 from the shelf above it, these items may obstruct the normal diffusion of moisture, leading to uneven humidification or reduced efficiency. When the air vents of the humidification component 103 are blocked, the released moisture cannot be evenly distributed within the storage compartment 102, resulting in insufficient humidity in some areas and excessive humidity in others. This not only affects the overall humidity balance within the refrigeration equipment but may also damage some items due to unsuitable humidity levels. To achieve the preset humidity level, the humidifier 103 may operate continuously, attempting to overcome the resistance caused by the blocked air vents. This can lead to energy waste and premature wear of the equipment. Prolonged operation with the air vents blocked may accelerate the aging of the humidifier 103 due to overheating, overload, and other issues, shortening its lifespan. Furthermore, blocked air vents can also cause other maintenance problems for the humidifier 103.

[0048] Reference Figure 2 As shown, it can be understood that an air vent 209 is provided on the side wall of the storage compartment 102, and the cabinet 101 has a first channel. One end of the first channel is connected to the humidification component 103, and the other end is connected to the air vent 209. After the fan 202 is turned on, the airflow passes over the water storage component 201 to form a high-humidity airflow. The high-humidity airflow enters the first channel along the humidification channel and flows into the storage compartment 102 through the air vent 209, thereby increasing the humidity in the storage compartment 102. Since the air vent 209 is located on the side wall of the storage compartment 102, it is at a relatively high position and is less likely to be blocked by bottles or other obstacles, thus ensuring the normal operation of the humidification component 103 and reducing the risk of the air vent 209 being blocked.

[0049] It should be noted that in some other embodiments, the vent 209 may also be located at the top of the storage compartment 102, with the vent 209 positioned from top to bottom.

[0050] Reference Figure 2As shown, it can be understood that the side wall of the storage compartment 102 is provided with three layers of air vents 209, which are spaced apart along the height direction of the cabinet 101, and the length of each layer of air vents 209 is basically the same. The side wall of the storage compartment 102 includes an air outlet area B, which is divided into multiple air outlet layers along the height direction of the cabinet 101. Specifically, along the top-to-bottom direction, the three layers of air vents 209 are defined as the first air outlet layer b1, the second air outlet layer b2, and the third air outlet layer b3, respectively. The total area of ​​all the air vents 209 in the first air outlet layer b1 is greater than the total area of ​​all the air vents 209 in the second air outlet layer b2, and the total area of ​​all the air vents 209 in the second air outlet layer b2 is greater than the total area of ​​all the air vents 209 in the third air outlet layer b3, thereby achieving an increase in the air volume of the air outlet area B from bottom to top.

[0051] It should be noted that in some other embodiments, the side wall of the storage room 102 may be provided with one layer of air vents 209, two layers of air vents 209, or more than four layers of air vents 209, and there may also be one layer of air vents 209 located on the top wall of the storage room 102.

[0052] In related technologies, the air vents of the humidification component 103 are typically evenly distributed vertically. However, humid air is generally denser than dry air because water vapor molecules increase the mass of the same volume of air upon entering. Vertically, temperature typically decreases with altitude, creating a temperature gradient. Humid air increases in density during cooling and thus sinks. Furthermore, during humidification, most of the air blown by the fan 202 tends to exit from the vents closest to the fan 202, resulting in only a small portion of the air blowing out from the vents furthest from the fan 202, leading to uneven humidity distribution across the vents. Specifically, the lower vents, closer to the fan 202, have a higher airflow rate, while the upper vents, further away, have a lower airflow rate. If the air vents of the humidification component 103 were evenly distributed vertically, the lower area would have higher humidity, while the upper area would have lower humidity, due to the sinking of humid air and structural limitations.

[0053] In this embodiment, by designing the air volume of the air outlet area B to increase from bottom to top, more airflow is allowed to flow out through the upper air outlet 209, reducing the impact of the sinking of high-humidity air and the limitations of its own structure, thereby achieving dynamic humidification balance in each area and improving humidity uniformity.

[0054] Reference Figure 2As shown, it can be understood that in some embodiments, the air outlet areas of all the vents 209 are different; the higher the layer in which the vent 209 is located, the larger the air outlet area of ​​the corresponding vent 209. Specifically, the air outlet area of ​​any vent 209 in the first air outlet layer b1 is greater than that of any vent 209 in the second air outlet layer b2, and the air outlet area of ​​any vent 209 in the second air outlet layer b2 is greater than that of any vent 209 in the third air outlet layer b3. By increasing the air outlet area of ​​each individual vent 209 layer by layer, the air volume of the air outlet area B increases from bottom to top, ensuring the uniformity of humidity in different height areas.

[0055] In related technologies, the humidification component 103 has only one air outlet per layer, meaning the air outlet is continuous and uninterrupted. Most of the air blown by the fan 202 tends to flow out from the end of the air outlet closest to the fan 202, resulting in only a small portion of the air reaching the other end. This uneven airflow within the same layer reduces humidification efficiency. (Refer to...) Figure 2 As shown, each layer of the embodiment of the present invention has multiple air outlets 209. Since the multiple air outlets 209 are spaced apart along the direction away from the fan 202, the air outlet area of ​​a single air outlet 209 is small, so that the high humidity air cannot be concentrated from the few air outlets 209 close to the fan 202. More high humidity air will flow away from the fan 202, thereby improving the humidification efficiency.

[0056] Reference Figure 2 As shown, it can be understood that in some embodiments, the density of each layer of air outlets 209 increases from bottom to top. Specifically, along the arrangement direction of the air outlets 209 in the same layer, the distance between two adjacent air outlets 209 in the first air outlet layer b1 is L1, the distance between two adjacent air outlets 209 in the second air outlet layer b2 is L2, and the distance between two adjacent air outlets 209 in the third air outlet layer b3 is L3, satisfying: L1 < L2 < L3. In other words, when the length of each layer of air outlets 209 is basically equal, the number of air outlets 209 in each layer gradually increases from bottom to top. This results in less airflow from the fan 202 in the air outlet unit b3, more airflow in the air outlet unit b2, and more airflow from the air outlet unit b1. This achieves an increase in the airflow volume of the air outlet area B from bottom to top, ensuring the uniformity of humidity in different height areas.

[0057] It is understood that in some other embodiments, the density of the air outlet holes 209 in each layer is the same, and the number of air outlet holes 209 in each layer increases from bottom to top. For example, the third air outlet layer b3 has 7 air outlet holes 209, the second air outlet layer b2 has 8 air outlet holes 209, and the first air outlet layer b1 has 13 air outlet holes 209. This embodiment can also achieve an increase in the air volume of the air outlet area B from bottom to top, ensuring the uniformity of humidity in different height areas.

[0058] Reference Figure 1 and Figure 2 As shown, it can be understood that the refrigeration equipment includes a shelf 106 on which items are placed. The shelf 106 supports the items, and users can place different items on the shelf 106 of the refrigeration equipment as needed. For example, in a refrigerator or freezer, people may place food, beverages, or other items that need to be refrigerated on the shelf 106. One of the main functions of the shelf 106 is to support the items placed on it. To achieve this purpose, the shelf 106 is usually made of sturdy materials, such as metal or high-strength plastic, to ensure that it can withstand a certain weight without deforming or being damaged. In addition, some shelves 106 are also designed with special supports or sliding supports to accommodate items of different sizes and shapes.

[0059] Reference Figure 2 As shown, it can be understood that the first passage is equipped with a vent 209 located below the shelf 106. When the vent 209 is located near the top of the storage compartment 102, this position is relatively high, and wine bottles are generally not placed at this height, thus ensuring that the vent 209 is not obstructed. When the vent 209 is located on the side wall of the storage compartment 102 and below the shelf 106, even if wine bottles or other items are placed on the shelf 106, the vent 209 will not be obstructed by the wine bottles or other items because it is located below.

[0060] Understandably, the shelf 106 is made of wood, which possesses unique moisture absorption and release properties, enabling it to regulate the humidity environment within the refrigeration equipment to some extent. As a natural material, wood inherently has a certain capacity for moisture absorption and release. In a wine cabinet, the wooden shelf 106 can help regulate humidity to some extent, especially when humidity fluctuations are minimal; its slight adjustment may help maintain relative humidity stability within the wine cabinet. When the humidity inside the wine cabinet suddenly rises or falls, the wooden shelf 106 can act as a "buffer," slowing down the rate of humidity change and thus providing a more stable storage environment for the wines.

[0061] Understandably, the shelf 106 is equipped with moisture-permeable holes 107, allowing humid air to pass through and facilitating communication between the upper and lower areas of the shelf 106. The moisture-permeable holes 107 in the shelf 106 are designed to promote the circulation of humid air between the upper and lower areas of the shelf 106. This design ensures uniform humidity and temperature distribution, preventing mold or odors from developing in localized areas due to excessive humidity or temperature. The moisture-permeable holes 107 effectively prevent damage to items caused by uneven humidity or temperature. This is especially important when storing humidity-sensitive items, such as wine bottles under the wooden shelf 106, as the moisture-permeable holes 107 reduce the risk of damage from a damp environment.

[0062] Reference Figure 1 and Figure 2 As shown, the cabinet 101 has a second channel, and the humidification component 103 is connected to the second channel. The second channel has a return air vent 105, which is located on the side wall of the storage chamber 102. The return air vent 105 and the exhaust vent 209 are located on opposite sides of the storage chamber 102. The return air vent 105 is generally located on one side of the storage chamber 102, near the bottom. This design helps the sinking, humid air mix with the dry air in the storage chamber 102 before entering from below, improving the overall humidification effect through internal circulation and ensuring uniform humidity distribution. The exhaust vent 209 is located on the other side of the storage chamber 102, near the top. By placing the return air vent 105 and the exhaust vent 209 on opposite sides of the storage chamber 102, airflow short-circuiting can be avoided, preventing humid air from being directly exhausted and flowing back to the humidification component 103 through the return air vent 105 without sufficient mixing with dry air, thus improving humidification efficiency and stability. The return air vent 105 and the outlet air vent 209 are designed diagonally to maximize the airflow path and allow the high-humidity air to mix thoroughly with the dry air in the storage compartment 102.

[0063] Understandably, the sum of the areas of all return vents 105 is greater than the sum of the areas of all outlet vents 209. In refrigeration equipment, the area design of the return vents 105 needs to ensure sufficient airflow. A larger return vent area helps increase the amount of dry air entering the humidification unit 103, promotes more air circulation, and improves the humidification efficiency of the humidification unit 103. A larger return vent area reduces pressure loss during airflow, thereby reducing energy consumption. A larger return vent area also reduces noise during airflow, improving the system's quietness.

[0064] Reference Figure 3As shown, it can be understood that the cabinet 101 includes a liner 301 and an insulation layer. The insulation layer covers the outer layer of the liner 301, and the interior of the liner 301 forms a storage compartment 102. The air outlet is located between the insulation layer and the liner 301. (Refer to...) Figure 3 and Figure 4 As shown, the cabinet 101 includes a first air duct 302, which defines a first channel. When using the refrigeration equipment, users will not see a messy air duct layout, thus improving the overall aesthetics.

[0065] It should be noted that in some other embodiments, the cabinet 101 may not be provided with the first air duct 302, that is, the first channel may be directly defined by the liner 301 and the insulation layer. For example, an air guide groove is provided on the insulation layer, and the groove opening of the air guide groove is attached to the outer surface of the liner 301 to form the first channel.

[0066] Reference Figure 4 As shown, the first air duct 302 includes a first air guide section 304, which is located at the junction of adjacent side walls of the storage compartment 102 and is arranged along the height direction of the cabinet 101. The bottom end of the first air guide section 304 is connected to the humidification component 103. Specifically, the opening at the bottom end of the first air guide section 304 is defined as a first port 401, which faces the humidification component 103. A first air guide portion 402 is provided between the humidification component 103 and the first air guide section 304. One end of the first air guide portion 402 is connected to the first port 401, and the other end is connected to the second mounting groove 206 where the water storage component 201 is located. The airflow blown by the fan 202 passes through the water storage component 201, enters the first air guide section 304 through the first air guide portion 402, and flows upward. The first air guide section 304 is located at the two corners of the back of the tank 301, reducing the storage area occupied.

[0067] Reference Figure 3 As shown, the first air duct 302 includes a second air guide section 305. The second air guide section 305 is located on the outer side wall of the storage room 102 and is arranged horizontally. The air outlet 209 connects to the second air guide section 305. Multiple air outlets 209 are arranged along the depth direction of the refrigeration equipment, so that the high-humidity air behind the storage room 102 can be delivered to the front of the storage room 102. The first air guide section 304 is arranged along the height direction of the cabinet 101, delivering the high-humidity air to multiple second air guide sections 305 at different heights. The second air guide sections 305 are arranged horizontally, allowing the high-humidity air to be blown out from different heights and depths, thereby improving the uniformity of humidification.

[0068] Reference Figure 4As shown, it can be understood that the cabinet 101 includes a second air duct 303, which defines a return air channel. The bottom end of the second air duct 303 is connected to the humidification component 103. Specifically, the opening at the bottom end of the second air duct 303 is defined as a second port 403, which faces the humidification component 103. A second air guide 404 is provided between the humidification component 103 and the second air duct 303. One end of the second air guide 404 is connected to the second port 403, and the other end is connected to the first mounting slot 205 where the ventilator 202 is located.

[0069] Reference Figure 5 and Figure 6 As shown, it can be understood that the refrigeration component includes an evaporator 601. In related technologies, the humidification component 103 is located below the evaporator 601. When the refrigeration equipment is defrosting, the defrosting water produced falls onto the humidification component 103 under the action of gravity, which can replenish water to the humidification component 103, thereby recovering the defrosting water, effectively reducing the frequency of water addition by the user, and realizing the recycling of defrosting water.

[0070] Specifically, refer to Figure 4 As shown, the cover plate 207 is provided with a water receiving trough 208, which is located below the evaporator 601. The water receiving trough 208 collects and guides water flow, channeling the collected condensate / defrost water into the water storage unit 201. For example, when the refrigeration equipment is defrosting, the generated defrost water falls into the water receiving trough 208 under gravity. The defrost water then returns to the water storage unit 201 along the water receiving trough 208 for reuse, effectively reducing the frequency of water refills. The humidification component 103 is also provided with a water inlet located on the bottom wall of the water receiving trough 208. Water from the water receiving trough 208 flows into the interior of the water storage unit 201 through the water inlet, replenishing the water storage unit 201.

[0071] By installing a water collection tank 208 below the evaporator 601, the condensate produced by the evaporator 601 is effectively collected and guided. This water is then used to evaporate through humidifying materials, thereby humidifying the air. This design not only improves water resource utilization but also reduces the frequency of water replenishment by the user.

However, the present invention 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 invention.
