Abstract
Description
Technical Field
[0001] This application belongs to the field of refrigeration and storage technology, and particularly relates to a moisture-retaining drawer and storage device. Background Technology
[0002] With the development of the refrigeration and storage equipment industry, the functions of storage equipment have become more diverse. In terms of preservation, various technologies have been developed to extend the storage time of food and preserve its original flavor to the greatest extent. Currently, most preservation solutions are achieved by installing airtight drawers inside storage equipment. However, this method greatly reduces gas convection inside the drawer, leading to uneven internal temperature distribution. Consequently, irreversible condensation can occur on the inner surface of the drawer under the combined effects of humidity and temperature.
[0003] In related technologies, solutions for this type of condensation include, but are not limited to, increasing the gap between the drawer body and the cover, drilling holes in the cover, or drilling holes in the back of the drawer. Regardless of the method used, the underlying logic is to create convection to allow some cool air to be blown into the drawer to balance the temperature inside the drawer. However, the introduction and expulsion of airflow will inevitably reduce the airtightness of the drawer, causing the moisture inside the drawer to dissipate with the airflow, which will have a relatively serious negative impact on the drawer's moisture retention and freshness preservation performance. Utility Model Content
[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a humidifying drawer and storage device that reduces the temperature gradient and decreases the occurrence of condensation without sacrificing humidification performance.
[0005] In a first aspect, this application provides a moisture-retaining drawer, comprising:
[0006] The drawer body forms a moisture-retaining space for storage, has an opening, and includes connected drawer compartments and a front panel. The drawer compartment includes a first panel to a fourth panel. The first panel, the second panel, the third panel, and the front panel are connected end to end and are all adjacent to the opening. The front panel and the second panel are arranged opposite each other along a first direction. The first panel and the third panel are arranged opposite each other along a second direction. The fourth panel and the opening are arranged opposite each other along a third direction. The first direction, the second direction, and the third direction intersect each other.
[0007] A metal heat transfer element is installed at least one of the first plate, the second plate, the third plate, and the fourth plate.
[0008] According to the humidifying drawer of this application, by installing a metal heat transfer component on at least one plate of the drawer drawer, the temperature difference between the high-temperature field and the low-temperature field in the humidifying space can be reduced without sacrificing the humidifying performance. This significantly reduces the temperature gradient, alleviates the local water vapor accumulation caused by excessive temperature difference, and thus reduces the occurrence of condensation. At the same time, it makes the water vapor distribution in the humidifying space more uniform, thereby greatly reducing local supersaturation condensation. This further greatly reduces the condensation problem caused by excessive temperature difference between the food and the original temperature in the humidifying space. Moreover, the metal heat transfer component can quickly adapt to external temperature fluctuations and adjust the internal thermal balance in real time, thereby effectively alleviating the periodic condensation caused by the lag in temperature field changes. In addition, the metal heat transfer component can also serve as a buffer for the internal and external temperature difference, effectively alleviating the situation where low-temperature cold air directly acts on the drawer body, thereby reducing local overcooling and further improving the condensation problem.
[0009] According to one embodiment of this application, the metal heat transfer element is elongated, and the extending direction of the metal heat transfer element includes at least the length direction of the corresponding plate.
[0010] According to one embodiment of this application, multiple metal heat transfer elements are installed on the same plate, and the multiple metal heat transfer elements are spaced apart along the third direction on the first plate, the second plate, and the third plate; wherein...
[0011] At least two sets of the metal heat transfer elements installed on the first plate, the second plate, and the third plate are staggered in the third direction.
[0012] According to one embodiment of this application, a plurality of metal heat transfer elements mounted on the first plate and a plurality of metal heat transfer elements mounted on the third plate are arranged flush with each other in the third direction, and are staggered with a plurality of metal heat transfer elements mounted on the second plate in the third direction.
[0013] According to one embodiment of this application, at least two of the metal heat transfer elements mounted on the first plate, the metal heat transfer element mounted on the second plate, and the metal heat transfer element mounted on the third plate are integrated into one unit.
[0014] According to one embodiment of this application, each of the drawer compartments has a first mounting groove on its outer surface away from the moisture-retaining space, and the metal heat transfer component is embedded in the first mounting groove.
[0015] According to one embodiment of this application, each of the drawer compartments has a second mounting groove on its inner surface facing the humidification space, and the metal heat transfer component is embedded in the second mounting groove.
[0016] According to one embodiment of this application, the metal heat transfer element is fitted to the inner surface of the drawer facing the humidification space.
[0017] According to one embodiment of this application, the metal heat transfer element is integrally formed with the drawer, and the metal heat transfer element is enclosed inside the drawer.
[0018] According to one embodiment of this application, the panel is provided with the metal heat transfer element.
[0019] According to one embodiment of this application, the humidifying drawer further includes:
[0020] A heat-containing cover is provided to seal the opening and is equipped with the metal heat transfer element.
[0021] Secondly, this application provides a storage device, which includes:
[0022] The humidifying drawer as described in any of the above solutions.
[0023] According to the storage device of this application, by setting up the aforementioned humidifying drawer, the temperature difference between the high-temperature field and the low-temperature field in the humidifying space can be reduced without sacrificing the humidifying performance. This significantly reduces the temperature gradient, alleviates the local water vapor accumulation caused by excessive temperature difference, and thus reduces the occurrence of condensation. At the same time, it makes the water vapor distribution in the humidifying space more uniform, thereby greatly reducing local supersaturation condensation. This further greatly reduces the condensation problem caused by excessive temperature difference between the food and the original temperature in the humidifying space. Moreover, the metal heat transfer component can quickly adapt to external temperature fluctuations and adjust the internal thermal balance in real time, thereby effectively alleviating the periodic condensation caused by the lag in temperature field changes. In addition, the metal heat transfer component can also serve as a buffer for the internal and external temperature difference, effectively alleviating the situation where low-temperature cold air directly acts on the drawer body, thereby reducing local overcooling and further improving the condensation problem.

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 application, and should not be construed as limiting this application.

[0044] This application discloses a moisture-retaining drawer.
[0045] The following is for reference. Figures 1-10 A moisture-retaining drawer according to an embodiment of this application is described.
[0046] In some embodiments, such as Figures 1-3 As shown, the humidifying drawer includes: a drawer body 1 and a metal heat transfer element 50. The drawer body 1 forms a humidifying space 30 for storage. The drawer body 1 has an opening 40 and includes connected drawer drawers 10 and panels 20. The drawer drawer 10 includes a first plate 10a to a fourth plate 10d. The first plate 10a, the second plate 10b, the third plate 10c and the panel 20 are connected end to end and are all adjacent to the opening 40. The panel 20 and the second plate 10b are arranged opposite each other along a first direction. The first plate 10a and the third plate 10c are arranged opposite each other along a second direction. The fourth plate 10d is arranged opposite to the opening 40 along a third direction. The first direction, the second direction and the third direction intersect each other. The metal heat transfer element 50 is installed at least one of the first plate 10a, the second plate 10b, the third plate 10c and the fourth plate 10d.
[0047] The metal heat transfer element 50 may be distributed in, but is not limited to, the following forms:
[0048] As an example, such as Figures 1-3 As shown, the metal heat transfer element 50 is installed on the first plate 10a, the second plate 10b and the third plate 10c.
[0049] As an example, the metal heat transfer element 50 is mounted on the second plate 10b.
[0050] As an example, the metal heat transfer element 50 is mounted on the first plate 10a and the third plate 10c.
[0051] As an example, the metal heat transfer element 50 is mounted on the first plate 10a, the second plate 10b, the third plate 10c and the fourth plate 10d.
[0052] It should be noted that there are various distribution forms of the metal heat transfer element 50, which are not exhaustive and will not be elaborated here.
[0053] The metal heat transfer element 50 can be made of aluminum, aluminum alloy, copper, copper alloy or other materials with excellent thermal conductivity, and this application embodiment does not limit this.
[0054] The metal heat transfer element 50 can be designed as a strip structure, a plate structure, or a foil structure, etc., and the embodiments of this application do not limit this.
[0055] In some embodiments, the metal heat transfer element 50 may be embedded in the outer or inner surface of the drawer 10; in other embodiments, the metal heat transfer element 50 may be directly attached to the outer or inner surface of the drawer 10; in still other embodiments, the metal heat transfer element 50 may be embedded in the interlayer of the drawer 10, and the embodiments of this application do not limit this.
[0056] In actual operation, due to various factors, the temperature received by the drawer body 1 in different directions will inevitably vary, resulting in temperature differences between the various panels of the drawer body 1. This causes high-temperature and low-temperature fields to form in the internal humidity-retaining space 30. It should be noted that during the long-term operation of the storage equipment, the temperature distribution around the drawer body 1 is constantly changing due to factors such as changes in the cooling cycle. For example, the temperature of the first panel 10a may be higher at a certain time, but it may be lower in the next time while the other panels are higher. Therefore, the specific locations of the high-temperature and low-temperature fields formed in the internal humidity-retaining space 30 are not fixed and will change with the changes in the external temperature distribution. It is impossible to arbitrarily define a certain area as always being at a high or low temperature. Furthermore, since the humidity-retaining space 30 can be regarded as a closed space without external disturbance, the internal temperature changes relatively slowly at low temperatures. This makes it difficult to eliminate internal temperature differences in a short time once they are formed. Based on this, in practical applications, the specific distribution of the metal heat transfer components 50 can be selected according to the specifications of the drawer body 1 and actual cost requirements. For example, refer to Figures 1-3 The diagram shows the most common drawer body 1 available. Drawer body 1 has the largest dimension in the second direction, followed by the first direction, and the smallest dimension in the third direction. Since a longer heat transfer path results in a larger temperature difference, the temperature difference between the first plate 10a and the third plate 10c is relatively difficult to adjust for this type of drawer body 1. Therefore, from a cost-saving perspective, at least a metal heat transfer element 50 needs to be installed on the second plate 10b. If there is still a budget constraint, it is preferable to add metal heat transfer elements 50 to the first plate 10a and the third plate 10c, and secondarily to add them to the fourth plate 10d. Other drawer body 1 specifications can also be designed according to the above principles, which will not be elaborated here.
[0057] It should be noted that since the fourth plate 10d is the plate used to directly support food in the humidifying drawer, the food in the humidifying space 30 will be in long-term contact with the fourth plate 10d. Therefore, the metal heat transfer component 50 is not suitable for installation by embedding or attaching it to the inner surface of the drawer 10. Furthermore, since any protrusion at the bottom of the drawer 10 will interfere with the sliding process of the humidifying drawer, the metal heat transfer component 50 is also not suitable for installation by attaching it to the outer surface of the drawer 10. In addition, if the metal heat transfer component 50 is installed on the fourth plate 10d by embedding it to the outer surface of the drawer 10, the metal heat transfer component 50 will be subjected to stress from its own weight, the weight of the food in the humidifying space, and the vibration from pushing and pulling during use, which can easily cause it to loosen and scratch. Therefore, the metal heat transfer component 50 is also not suitable for installation in this way. In summary, the most suitable way to install the metal heat transfer component 50 on the fourth plate 10d is to embed the metal heat transfer component 50 into the interlayer of the fourth plate 10d. However, this installation method is extremely difficult. Therefore, in practical applications, even if the metal heat transfer component 50 can be installed on the fourth plate 10d through a complex process, from the perspective of cost-effectiveness and practicality, the priority of considering the metal heat transfer component 50 on the first plate 10a, the second plate 10b, and the third plate 10c is far higher than that on the fourth plate 10d.
[0058] Understandably, by installing a metal heat transfer element 50 on the drawer 10, the excellent thermal conductivity of metal allows heat to be transferred from high-temperature areas to low-temperature areas, promoting heat exchange between the high-temperature and low-temperature fields within the humidification space 30. For example, when a certain plate is at a higher temperature, the metal heat transfer element 50 absorbs heat and conducts it to the lower-temperature plate, making the temperature distribution within the entire humidification space 30 more uniform and reducing the temperature gradient. This alleviates localized water vapor accumulation caused by excessive temperature differences, thereby reducing condensation. Unlike related technologies that balance temperature through methods such as seams or perforations, the metal heat transfer element 50 achieves temperature balance without compromising the drawer's airtightness. Because the drawer maintains good airtightness, internal moisture does not dissipate with airflow, thus preserving the drawer's humidification performance and better keeping food fresh, retaining its original flavor to the greatest extent. On the other hand, since the water vapor content varies with temperature under the same humidity, a large temperature difference within the humidification space 30 can lead to significant differences in water vapor content at different locations, making condensation more likely. The metal heat transfer component 50 can effectively reduce the temperature difference, resulting in a more uniform distribution of water vapor content within the humidification space 30, further suppressing condensation. Simultaneously, the metal heat transfer component 50 reacts rapidly to temperature changes, quickly adjusting the temperature when new food is placed inside, reducing condensation caused by excessive temperature differences between the food and the existing temperature within the humidification space 30. Furthermore, the metal heat transfer component 50 can also act as a buffer zone for internal and external temperature differences. When cold air from outside attempts to enter the humidification space 30, the metal heat transfer component 50 can absorb some of the heat from the cold air, mitigating the direct impact of the cold air on the drawer body 1, and evenly distributing the external cold air within the drawer's humidification space 30, reducing localized overcooling and further improving the condensation problem.
[0059] The humidifying drawer provided in this application embodiment, by installing a metal heat transfer element 50 on at least one plate of the drawer 10, can reduce the temperature difference between the high-temperature field and the low-temperature field of the humidifying space 30 without sacrificing the humidifying performance, significantly reduce the temperature gradient, alleviate the local water vapor enrichment caused by excessive temperature difference, thereby reducing the occurrence of condensation, and at the same time make the water vapor distribution in the humidifying space 30 more uniform, thereby greatly reducing local supersaturation condensation, and further greatly reducing the condensation problem caused by the large temperature difference between the food and the original temperature in the humidifying space 30. Moreover, the metal heat transfer can quickly adapt to external temperature fluctuations and adjust the internal thermal balance in real time, thereby effectively alleviating the periodic condensation caused by the lag in temperature field changes. In addition, the metal heat transfer element 50 can also serve as a buffer for the internal and external temperature difference, effectively alleviating the situation where low-temperature cold air directly acts on the drawer body 1, thereby reducing local overcooling and further improving the condensation problem.
[0060] In some embodiments, such as Figures 1-3As shown, the metal heat transfer element 50 is elongated, and the extension direction of the metal heat transfer element 50 includes at least the length direction of the corresponding plate.
[0061] In this embodiment, with Figures 1-3 For example, when a strip-shaped metal heat transfer element 50 is installed on the first plate 10a, since the length direction of the first plate 10a is the first direction, the extension direction of the metal heat transfer element 50 installed on the first plate 10a includes at least the first direction; when a strip-shaped metal heat transfer element 50 is installed on the second plate 10b, since the length direction of the second plate 10b is the second direction, the extension direction of the metal heat transfer element 50 installed on the second plate 10b includes at least the second direction; when a strip-shaped metal heat transfer element 50 is installed on the third plate 10c, since the length direction of the third plate 10c is the third direction, the extension direction of the metal heat transfer element 50 installed on the first plate 10a includes at least the third direction; when a strip-shaped metal heat transfer element 50 is installed on the fourth plate 10d, since the length direction of the fourth plate 10d is the second direction, the extension direction of the metal heat transfer element 50 installed on the fourth plate 10d includes at least the second direction.
[0062] In other embodiments, the metal heat transfer element 50 may also be mesh-shaped. When a mesh-shaped metal heat transfer element 50 is installed on the first plate 10a, since the length direction of the first plate 10a is the first direction, the extension direction of the metal heat transfer element 50 installed on the first plate 10a may include the first direction and a third direction. When a mesh-shaped metal heat transfer element 50 is installed on the second plate 10b, since the length direction of the second plate 10b is the second direction, the extension direction of the metal heat transfer element 50 installed on the second plate 10b may include the second direction and a third direction. When a mesh-shaped metal heat transfer element 50 is installed on the third plate 10c, since the length direction of the third plate 10c is the first direction, the extension direction of the metal heat transfer element 50 installed on the third plate 10c may include the first direction and a third direction. When a mesh-shaped metal heat transfer element 50 is installed on the fourth plate 10d, since the length direction of the fourth plate 10d is the second direction, the extension direction of the metal heat transfer element 50 installed on the fourth plate 10d may include the first direction and a second direction.
[0063] The humidifying drawer provided in this application embodiment, when the metal heat transfer element 50 extends along the length of the plate as described above, can cover the entire length of the plate with its heat capacity. Since the longer the path, the greater the temperature difference, the metal heat transfer element 50 can capture a wider range of temperature differences and directionally transfer heat from the high-temperature end to the low-temperature end through heat conduction, expanding the temperature balance range. This allows for more uniform absorption and release of heat, suppressing the temperature gradient in the direction of maximum size within the humidifying space 30, thereby reducing the risk of condensation caused by localized thermal stress concentration. Compared to block or sheet-shaped heat transfer elements, the elongated design reduces material usage while maintaining heat conduction efficiency. By rationally selecting the extension direction and installation position, a larger temperature difference area can be covered with less material, thus saving on the production cost of the humidifying drawer.
[0064] In some embodiments, such as Figures 1-3 As shown, multiple metal heat transfer elements 50 are installed on the same plate, and the multiple metal heat transfer elements 50 are distributed at intervals along the third direction on the first plate 10a, the second plate 10b and the third plate 10c; wherein, among the multiple metal heat transfer elements 50 installed on the first plate 10a, the multiple metal heat transfer elements 50 installed on the second plate 10b and the multiple metal heat transfer elements 50 installed on the third plate 10c, at least two sets of metal heat transfer elements 50 are staggered in the third direction.
[0065] In this context, "multiple" refers to two or more. When multiple plates are equipped with metal heat transfer elements 50, the number of metal heat transfer elements 50 provided on the multiple plates may be the same or different. This application embodiment does not impose any restrictions on this.
[0066] In some embodiments, the plurality of metal heat transfer elements 50 mounted on the first plate 10a and the plurality of metal heat transfer elements 50 mounted on the third plate 10c are aligned one by one in the third direction, and both are staggered with the plurality of metal heat transfer elements 50 mounted on the second plate 10b in the third direction.
[0067] In other embodiments, at least two sets of metal heat transfer elements 50 installed on the first plate 10a, the second plate 10b, and the third plate 10c are staggered in a third direction among the plurality of metal heat transfer elements 50 installed on the first plate 10a, the second plate 10b, and the third plate 10c.
[0068] In some other embodiments, the plurality of metal heat transfer elements 50 mounted on the first plate 10a and the plurality of metal heat transfer elements 50 mounted on the second plate 10b are aligned one by one in the third direction, and both are staggered with the plurality of metal heat transfer elements 50 mounted on the third plate 10c in the third direction.
[0069] The humidifying drawer provided in this application embodiment, by installing multiple metal heat transfer elements 50 spaced apart on the same plate as described above, can cover different areas of the first plate 10a, second plate 10b, and third plate 10c in the third direction. This increases the contact area between the metal heat transfer elements 50 and the drawer body 1, thereby more comprehensively sensing and conducting heat, improving heat conduction efficiency, and thus enhancing the heat response speed. At the same time, the staggered arrangement allows the metal heat transfer elements 50 on different plates to form a staggered arrangement in the third direction, and the metal heat transfer elements 50 on different plates can complement each other to form a denser heat conduction path, increasing the heat conduction path in the third direction, thereby expanding the heat exchange range within the entire humidifying space 30, making the temperature distribution more uniform, and thus minimizing condensation.
[0070] In some embodiments, such as Figure 8 As shown, the multiple metal heat transfer elements 50 installed on the first plate 10a and the multiple metal heat transfer elements 50 installed on the third plate 10c are arranged flush with each other in the third direction, and are staggered with the multiple metal heat transfer elements 50 installed on the second plate 10b in the third direction.
[0071] Understandably, on the one hand, the multiple metal heat transfer components 50 installed on the first plate 10a and the multiple metal heat transfer components 50 installed on the third plate 10c are highly aligned, forming symmetrical heat conduction paths on the first plate 10a and the third plate 10c. This allows for rapid response to asymmetrical temperature disturbances along the second direction, such as when hot food is placed on one side, maintaining the temperature uniformity of the drawer body 1 along the second direction and minimizing condensation caused by uneven temperature on one side. On the other hand, the multiple metal heat transfer components 50 installed on the second plate 10b are staggered with the aforementioned two components, forming a third-direction heat conduction compensation. This allows heat from the second plate 10b to be quickly conducted to the first plate 10a and the third plate 10c through the staggered points, accelerating the thermal balance of the preservation space in the first direction. This significantly reduces the temperature difference between the front and back, suppressing condensation problems caused by direct cold air blowing on the second plate 10b in some scenarios. On the other hand, the symmetrical design of the two sides along the second direction simplifies the mold design and installation process, while the staggered design of the rear side relative to the two sides along the second direction means that multiple metal heat transfer components 50 do not need to be strictly positioned when assembled into the second plate 10b, which has high fault tolerance and thus significantly reduces the production and processing difficulty of the humidifying drawer.
[0072] In some embodiments, such as Figure 9 and Figure 10 As shown, at least two of the metal heat transfer elements 50 installed on the first plate 10a, the metal heat transfer element 50 installed on the second plate 10b, and the metal heat transfer element 50 installed on the third plate 10c are integrated into one unit.
[0073] In some implementations, such as Figure 9 As shown, the metal heat transfer element 50 mounted on the first plate 10a, the metal heat transfer element 50 mounted on the second plate 10b, and the metal heat transfer element 50 mounted on the third plate 10c can be integrated into one unit. In this case, the three metal heat transfer elements 50 respectively located on the first plate 10a, the second plate 10b, and the third plate 10c can be integrated into a U-shaped structure.
[0074] In other implementations, such as Figure 10 As shown, the metal heat transfer element 50 mounted on the first plate 10a and the metal heat transfer element 50 mounted on the second plate 10b can be integrated into one unit. In this case, the two metal heat transfer elements 50 respectively located on the first plate 10a and the second plate 10b can be integrated into an L-shaped structure.
[0075] In some other implementations, such as Figure 10 As shown, the metal heat transfer element 50 mounted on the first plate 10a and the metal heat transfer element 50 mounted on the third plate 10c can be integrated into one unit. In this case, the two metal heat transfer elements 50 respectively located on the first plate 10a and the third plate 10c can be integrated into an L-shaped structure.
[0076] The humidifying drawer provided in this application embodiment, through the above-described structural design that integrates the metal heat transfer components 50 installed on different plates into one unit, reduces the contact thermal resistance between the original independent heat transfer components, allowing heat to be transferred more efficiently from the high-temperature area to the low-temperature area without the need for transfer through the drawer body 1, thereby balancing the temperature of the humidifying space 30 more quickly. At the same time, it reduces the total number of parts in the humidifying drawer. The metal heat transfer components 50 on different plates do not need to undergo cumbersome independent assembly work; only the integrated whole needs to be installed, thereby greatly simplifying the assembly process and significantly reducing the time required for installation, which in turn helps to accelerate the production efficiency of the humidifying drawer.
[0077] In some embodiments, such as Figure 4 and Figure 5 As shown, each drawer 10 has a first mounting groove 11 on its outer surface away from the humidification space 30, and the metal heat transfer component 50 is embedded in the first mounting groove 11.
[0078] As an example, such as Figure 4 and Figure 5As shown, the metal heat transfer component 50 can be installed on the first plate 10a, the second plate 10b, and the third plate 10c. The outer surfaces of the first plate 10a, the second plate 10b, and the third plate 10c can each be provided with a plurality of first mounting grooves 11 spaced apart along the third direction. The metal heat transfer component 50 is interference-fitted with the first mounting grooves 11. The plurality of first mounting grooves 11 on the first plate 10a, the plurality of first mounting grooves 11 on the second plate 10b, and the plurality of first mounting grooves 11 on the third plate 10c are arranged flush with each other in the third direction.
[0079] As an example, the metal heat transfer element 50 can be installed on the first plate 10a, the second plate 10b, and the third plate 10c. The outer surfaces of the first plate 10a, the second plate 10b, and the third plate 10c can each be provided with a plurality of first mounting grooves 11 spaced apart along a third direction. The metal heat transfer element 50 is interference-fitted with the first mounting grooves 11. The plurality of first mounting grooves 11 on the first plate 10a and the plurality of first mounting grooves 11 on the second plate 10b are flush with each other in a third direction, and both are offset from the plurality of first mounting grooves 11 on the third plate 10c in a third direction.
[0080] As an example, such as Figure 4 and Figure 5 As shown, the metal heat transfer element 50 can be installed on the first plate 10a, the second plate 10b, and the third plate 10c. The metal heat transfer element 50 installed on the first plate 10a, the metal heat transfer element 50 installed on the second plate 10b, and the metal heat transfer element 50 installed on the third plate 10c can be integrated into one unit. The outer surfaces of the first plate 10a, the second plate 10b, and the third plate 10c can be provided with a U-shaped and continuous first mounting groove 11. After the three metal heat transfer elements 50 are integrated, the cross plate and the first mounting groove 11 are interference-fitted.
[0081] It should be noted that, as Figure 4 and Figure 5 As shown, the metal heat transfer element 50 can be set flush with the outer surface of the drawer 10 to minimize dirt accumulation and reduce cleaning difficulty.
[0082] The humidifying drawer provided in this application embodiment, through the structural design of the metal heat transfer component 50 being embedded in the outer surface of the drawer 10 via the first mounting groove 11, greatly increases the contact area between the metal heat transfer component 50 and the drawer 10, reduces the contact thermal resistance, and thus enhances the heat conduction efficiency. At the same time, the metal heat transfer component 50 does not occupy the preservation space, nor does it directly contact the high humidity air in the humidifying space 30, reducing the risk of oxidation and corrosion of the surface of the metal heat transfer component 50 due to long-term moisture, thereby extending the service life of the metal heat transfer component 50.
[0083] In some embodiments, such as Figure 6 and Figure 7 As shown, the inner surface of the drawer 10 facing the moisturizing space 30 is provided with a second mounting groove 12, and the metal heat transfer component 50 is embedded in the second mounting groove 12.
[0084] As an example, such as Figure 6 As shown, the metal heat transfer component 50 can be installed on the first plate 10a, the second plate 10b, and the third plate 10c. The inner surfaces of the first plate 10a, the second plate 10b, and the third plate 10c can each be provided with a plurality of second mounting grooves 12 spaced apart along the third direction. The metal heat transfer component 50 is interference-fitted with the second mounting grooves 12. The plurality of second mounting grooves 12 on the first plate 10a, the plurality of second mounting grooves 12 on the second plate 10b, and the plurality of second mounting grooves 12 on the third plate 10c are flush with each other in the third direction.
[0085] As an example, such as Figure 7 As shown, the metal heat transfer element 50 can be installed on the first plate 10a, the second plate 10b, and the third plate 10c. The inner surfaces of the first plate 10a, the second plate 10b, and the third plate 10c can each be provided with a plurality of second mounting grooves 12 spaced apart along a third direction. The metal heat transfer element 50 is interference-fitted with the second mounting grooves 12. The plurality of second mounting grooves 12 on the first plate 10a and the plurality of second mounting grooves 12 on the second plate 10b are flush with each other in the third direction, and both are offset from the plurality of second mounting grooves 12 on the third plate 10c in the third direction.
[0086] As an example, such as Figure 4 and Figure 5 As shown, the metal heat transfer element 50 can be installed on the first plate 10a, the second plate 10b, and the third plate 10c. The metal heat transfer element 50 installed on the first plate 10a, the metal heat transfer element 50 installed on the second plate 10b, and the metal heat transfer element 50 installed on the third plate 10c can be integrated into one unit. The inner surfaces of the first plate 10a, the second plate 10b, and the third plate 10c can be provided with a U-shaped and continuous second mounting groove 12. After the three metal heat transfer elements 50 are integrated, the cross plate and the second mounting groove 12 are interference-fitted.
[0087] It should be noted that, as Figure 6 and Figure 7 As shown, the metal heat transfer element 50 can be set flush with the inner surface of the drawer 10 to minimize the accumulation of food residue or dirt and reduce the difficulty of cleaning.
[0088] The humidifying drawer provided in this application embodiment, through the structural design of the metal heat transfer component 50 embedded in the inner surface of the drawer 10 via the second mounting groove 12, allows the metal heat transfer component 50 to directly exchange heat with the air in the humidifying space 30, shortening the heat conduction path and accelerating the response speed of the metal heat transfer component 50 to temperature differences, making the temperature regulation of the humidifying space 30 more timely and accurate. At the same time, it greatly increases the contact area between the metal heat transfer component 50 and the drawer 10, reduces the contact thermal resistance, and thus enhances the heat conduction efficiency.
[0089] In some embodiments, the metal heat transfer element 50 is attached to the inner surface of the drawer 10 facing the humidification space 30.
[0090] Specifically, the metal heat transfer element 50 can be fitted to the inner surface of the drawer 10 facing the moisturizing space 30 by means of welding, snap-fitting or threaded connection, and this application embodiment does not limit this.
[0091] By setting the metal heat transfer component 50 to directly adhere to the inner surface of the drawer 10, the installation method is relatively simple. Moreover, after the adherence, the heat transfer component and the drawer 10 form a relatively stable whole. During the daily use of the humidifying drawer, such as opening and closing operations, the metal heat transfer component 50 is not easy to loosen or shift. At the same time, it is not easy to have cleaning dead corners, thus improving the overall cleanliness of the humidifying drawer.
[0092] In some embodiments, the metal heat transfer element 50 is integrally formed with the drawer 10, and the metal heat transfer element 50 is enclosed inside the drawer 10.
[0093] Specifically, the metal heat transfer component 50 can be integrally formed with the drawer 10 through processes such as insert injection molding, co-extrusion, or 3D printing. This application embodiment does not limit this.
[0094] By integrally molding the metal heat transfer component 50 with the drawer 10, the metal heat transfer component 50 becomes part of the structure of the drawer 10, reducing thermal resistance in the heat transfer path, maximizing the rate at which heat is transferred from the high-temperature area to the low-temperature area, minimizing the temperature gradient, and thus effectively suppressing condensation. At the same time, the metal heat transfer component 50 does not directly contact the high-humidity air in the humidification space 30, reducing the risk of oxidation and corrosion of the surface of the metal heat transfer component 50 due to long-term moisture, thereby extending the service life of the metal heat transfer component 50. Furthermore, since the metal heat transfer component 50 is encased inside the drawer 10, the inner and outer surfaces of the drawer 10 are smooth, without gaps or protrusions, making it easier to clean, reducing the accumulation of dust, dirt, and bacteria, and maximizing the cleanliness of the humidification drawer.
[0095] In some embodiments, the panel 20 is provided with a metal heat transfer element 50.
[0096] In this embodiment, the metal heat transfer element 50 can be embedded or attached to the inner surface of the panel 20 to maintain the aesthetics of the humidifying drawer.
[0097] In other embodiments, the metal heat transfer element 50 may also be embedded or attached to the outer surface of the panel 20.
[0098] In some other embodiments, the metal heat transfer element 50 may also be embedded in the interlayer of the panel 20.
[0099] The humidifying drawer provided in this application embodiment, by providing a metal heat transfer element 50 on the panel 20 as described above, extends the heat management range from the first plate 10a to the fourth plate 10d of the drawer 10 to the panel 20. This can quickly balance the temperature difference between the panel 20 and the drawer 10, alleviate the instantaneous thermal shock when the storage device door is opened, further reduce the temperature difference between the high temperature field and the low temperature field in the humidifying space 30, and minimize the temperature gradient, thereby further reducing the occurrence of condensation.
[0100] In some embodiments, the humidifying drawer further includes a humidifying cover.
[0101] The moisture-proof cover is used to seal the opening 40, and the moisture-proof cover is provided with a metal heat transfer element 50.
[0102] The moisturizing cover can be a flat plate structure covering the opening 40, or a cylindrical structure covering the drawer body 1 with one side open. This application embodiment does not limit this.
[0103] In this embodiment, the metal heat transfer element 50 can be embedded or attached to the inner surface of the moisturizing cover to maintain the aesthetics of the moisturizing drawer.
[0104] In other embodiments, the metal heat transfer element 50 may also be embedded or attached to the outer surface of the moisture-proof cover.
[0105] In some other embodiments, the metal heat transfer element 50 may also be embedded in the interlayer of the moisture-retaining cover.
[0106] The humidifying drawer provided in this application extends the heat management range to the humidifying cover by providing a metal heat transfer element 50 on the humidifying cover. This allows for rapid balancing of the temperature difference between the humidifying cover and the drawer 10, minimizing the temperature difference between the high-temperature field and the low-temperature field in the humidifying space 30, and maximizing the reduction of the temperature gradient, thereby minimizing the generation of condensate.

The storage devices have diverse structural forms and a wide range of applications.
[0110] The storage device provided in this application embodiment, through the aforementioned setting of the humidifying drawer, can reduce the temperature difference between the high-temperature field and the low-temperature field of the humidifying space 30 without sacrificing the humidifying performance, significantly reduce the temperature gradient, alleviate the local water vapor enrichment caused by excessive temperature difference, thereby reducing the occurrence of condensation, and at the same time make the water vapor distribution in the humidifying space 30 more uniform, thereby greatly reducing local supersaturation condensation, and further greatly reducing the condensation problem caused by the excessive temperature difference between the food and the original temperature in the humidifying space 30. In addition, the metal heat transfer can quickly adapt to external temperature fluctuations and adjust the internal thermal balance in real time, thereby effectively alleviating the periodic condensation caused by the lag in temperature field changes. Furthermore, the metal heat transfer component 50 can also serve as a buffer for the internal and external temperature difference, effectively alleviating the situation where low-temperature cold air directly acts on the drawer body 1, thereby reducing local overcooling and further improving the condensation problem.
