[0002] Current medical refrigerators typically use evaporators for cooling to lower the internal temperature and thus refrigerate the items inside. The evaporator requires electricity to maintain the internal temperature; if the power is cut off, the temperature inside the refrigerator rises rapidly, resulting in fast temperature fluctuations. To meet cooling demands, the evaporator needs frequent power supply, leading to a high operating rate, high power consumption, and ineffective cooling. Utility Model Content

Detailed Implementation
[0028] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0029] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.
[0030] The refrigerator will be described in detail below through specific embodiments:
[0031] Reference Figures 1 to 5 As shown in some embodiments of the present invention, a refrigerator box is provided, including a box body 1, a tray 2, and a door 3.
[0032] The cabinet 1 has a refrigeration chamber 11, and a refrigeration structure 4 for generating cold energy is provided inside the cabinet 1 to reduce the temperature inside the refrigeration chamber 11. A tray 2 is placed inside the refrigeration chamber 11, and a first cold storage structure for storing and releasing cold energy is provided on the tray 2. A door 3 is sealed on the cabinet 1, and a second cold storage structure for storing and releasing cold energy is provided on the door 3.
[0033] In practice, when the refrigeration structure 4 is powered on, it generates cooling energy to lower the temperature inside the refrigerator. At this time, the first cold storage structure on the tray 2 and the second cold storage structure on the door 3 can absorb and store the cooling energy generated by the refrigeration structure 4. When the refrigeration structure 4 is powered off and stops generating cooling energy, the cooling energy stored in the first and second cold storage structures can be released to prevent the temperature inside the refrigerator cavity 11 from rising too quickly and effectively suppress temperature fluctuations inside the refrigerator cavity 11. At the same time, it can also reduce the operating rate of the refrigeration structure 4, meet energy-saving requirements, and facilitate the storage of medicines. In addition, the first and second cold storage structures are respectively set in the refrigerator cavity 11 and on the door 3, which means that they can provide cooling energy to different areas inside the refrigerator 1 to reduce the temperature difference between different areas and improve the refrigeration effect.
[0034] In some embodiments, refer to Figure 1 As shown, the first cold storage structure has a first cold-conducting plane, and the second cold storage structure has a second cold-conducting plane, which intersect. It can be understood that the cold energy stored in the first cold storage structure can extend from the first cold-conducting plane in a direction away from it, and the cold energy stored in the second cold storage structure can extend from the second cold-conducting plane in a direction away from it. Since the first and second cold-conducting planes intersect, the cold energy can uniformly fill the entire three-dimensional space in different directions, effectively ensuring that there are no dead zones with excessive temperature deviations within the cold storage cavity 11.
[0035] In the specific implementation, continue to refer to Figure 1 As shown, the trays 2 and the first cooling plane are arranged horizontally, while the second cooling plane is arranged vertically, meaning the first and second cooling planes are perpendicular to each other. There are multiple trays 2, spaced evenly along the longitudinal direction. In other words, for the vertical refrigerator, the door 3 is a front-opening door. When the door 3 is opened, the multiple trays 2 are arranged longitudinally, facilitating the storage and retrieval of medicines. Correspondingly, the horizontal arrangement of the trays 2 and the first cooling plane allows for a large contact area with the cold energy to absorb and release it, while the vertical arrangement of the second cooling plane also allows for a large contact area with the cold energy to absorb and release it.
[0036] Of course, the tray 2 and the first and second cooling planes are arranged in other directions to accommodate different types of refrigerated boxes, and can be set up according to actual needs.
[0037] It should be noted that multiple trays 2 are arranged at equal intervals along the longitudinal direction, and the first cold-conducting planes arranged on the trays 2 are also arranged at equal intervals along the longitudinal direction. The trays can divide the space inside the cold storage cavity 11 into multiple areas, and multiple first cold storage structures release cold energy to multiple areas accordingly. With this arrangement, the cold energy in different areas inside the cold storage cavity 11 can be evenly distributed, avoiding dead corners with excessive temperature deviations inside the cold storage cavity 11.
[0038] Of course, the projection of multiple first cold storage structures onto the second cold storage structure can also divide the second cold storage plane into multiple parts, so as to further uniformly distribute the cold amount in different areas of the cold storage cavity 11 under the synergistic effect of the second cold storage structure. The specific settings can be made according to actual needs.
[0039] Reference Figure 1 As shown, a tray 2 can also be installed on the bottom wall of the box 1, which can increase the storage space for medicines, improve the cold storage capacity, reduce the temperature difference between different areas, and improve the refrigeration effect.
[0040] In some embodiments, refer to Figure 1 and Figure 2 As shown, the first cold storage structure includes a first cavity 21 integrally formed inside the tray 2. The first cavity 21 is filled with a cold storage medium to absorb and release cold energy. Specifically, the tray 2 is provided with a filling port 53, which communicates with the first cavity 21 to facilitate the filling and replacement of the cold storage medium.
[0041] Reference Figure 2 As shown, the top of the tray 2 is integrally formed with a groove 22 for storing medicines, and the groove 22 is located above the first cavity 21. When the medicine is placed on the tray 2, the cold storage medium in the first cavity 21 can release cold energy to the refrigeration cavity 11 to suppress temperature fluctuations in the refrigeration cavity 11, and can also directly cool the medicine in the tray 2, so that the medicine has a better storage effect.
[0042] It is understandable that the first cavity 21 and the groove 22 are integrally formed on the tray 2, and the first cold storage structure can be supported in the box 1 along with the tray 2, without the need for additional connection or support structures, which makes the structure of the refrigerated box simple.
[0043] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4 As shown, the second cold storage structure includes a cold storage box 5, which is located on the side of the door 3 facing the cabinet 1, so as to absorb the cold energy in the cold storage cavity 11 and release the cold energy toward the cold storage cavity 11. A second cavity 51 is formed inside the cold storage box 5, and the second cavity 51 is filled with a cold storage medium to absorb and release the cold energy through the cold storage medium.
[0044] Specifically, the cold storage box 5 is provided with a filling port 53, which is connected to the second cavity 51, enabling the filling and replacement of the cold storage medium. During manufacturing, the cold storage box 5 can be integrally foamed and molded based on the door body 3. The cold storage box 5 can be designed to fit the structure of the door body 3, thus making the cold storage box 5 suitable for various models and specifications of door bodies 3.
[0045] It is understandable that the cold storage box 5 and the door 3 are separate structures. With this design, there is no need to damage the structure of the refrigerator door 3; it is only necessary to connect the cold storage box 5 and the door 3.
[0046] Reference Figure 5 As shown, the cold storage box 5 and the door 3 are detachably connected. Specifically, the cold storage box 5 can be connected to the door 3 using fasteners such as screws, which makes disassembly and assembly simple and facilitates maintenance and replacement.
[0047] In some embodiments, refer to Figure 5 As shown, the surface of the cold storage box 5 is provided with a groove structure 52. By providing the groove structure 52, the surface area of the cold storage box 5 can be increased, which can increase the cooling efficiency.
[0048] Specifically, the trench structure 52 includes a first trench 521 and a second trench 522. The first trench 521 extends along a first direction, and the second trench 522 extends along a second direction. The first direction and the second direction intersect, that is, the first trench 521 and the second trench 522 extend along different directions, which can further increase the surface area of the cold storage box 5.
[0049] For example, the first direction is Figure 5 The middle left and right directions, the second direction is Figure 5 In the vertical direction, there are multiple first grooves 521 and multiple second grooves 522. The multiple first grooves 521 and multiple second grooves 522 are distributed in an interlaced manner, and the cold storage box 5 has a large surface area and high cooling efficiency.
[0050] In some embodiments, refer to Figure 1 As shown, a front panel 6 is provided on the rear inner wall of the housing 1. The front panel 6 and the rear inner wall of the housing 1 are spaced apart, and a refrigeration air duct 7 is formed between the front panel 6 and the rear inner wall of the housing 1. The refrigeration air duct 7 is connected to the refrigeration cavity 11, and the refrigeration structure 4 is arranged in the refrigeration air duct 7. In a specific implementation, the refrigeration structure 4 can be an irregularly shaped plate tube evaporator. Through its convex and concave aluminum plate surface, the heat conduction area of the gas can be increased.
[0051] It is understandable that the cooling duct 7 can reduce the temperature of the gas passing through the cooling duct 7 to form low-temperature gas. The cooling duct 7 is connected to the cold storage cavity 11 of the cabinet 1. Low-temperature gas can be delivered to the cold storage cavity 11 through the cooling duct 7 to reduce the temperature inside the cold storage cavity 11.
[0052] Specifically, the refrigeration duct 7 has an air inlet 71 and an air outlet 72. A gas flow loop is formed between the refrigeration chamber 11, the air inlet 71, the air outlet 72, and the refrigeration chamber 11. A fan 9 is installed in the gas flow loop. With this configuration, under the action of the fan 9, gas can enter the refrigeration duct 7 through the air inlet 71 in the refrigeration chamber 11, and it can also enter the refrigeration chamber 11 through the air outlet 72 in the refrigeration duct 7. That is, the gas can flow and circulate in the gas flow loop. During the circulation process, it can also be cooled through the refrigeration duct 7 to gradually reduce the temperature of the refrigeration chamber 11.
[0053] In practice, the fan 9 can be installed at the air inlet 71 to drive the gas to circulate in the gas flow loop. Of course, the fan 9 can also be installed at other locations in the gas flow loop. This application does not limit this, as long as it can drive the gas to circulate in the gas flow loop to gradually generate low-temperature gas and reduce the temperature of the cold storage chamber 11.
[0054] Reference Figure 1 As shown, an opening can be directly provided on the front panel 6 to form an air inlet 71 or an air outlet 72, or an air inlet 71 or an air outlet 72 can be formed in the gap between the front panel 6 and the inner wall of the housing 1. This application does not limit this and can be set according to actual needs.
[0055] Reference Figure 2 As shown, the refrigerator also includes a support structure 12 to support the tray 2, thereby fixing the tray 2 within the refrigerator cavity 11 of the box body 1.
[0056] In some embodiments, the support structure 12 includes a first support rib disposed on the front plate 6, and the tray 2 is supported on the first support rib. Specifically, the first support rib is directly formed on the front plate 6 and extends horizontally. In other embodiments, the support structure 12 includes a second support rib disposed on the inner walls of opposite sides of the housing 1, and the tray 2 is supported on the second support rib. Specifically, the second support rib is directly formed on the inner walls of opposite sides of the housing 1 and extends horizontally.
[0057] Of course, it should be noted that the support structure 12 can also be other structures, or the tray 2 can be supported by the first support rib and the second support rib. This application does not limit this, as long as it can support the tray 2 and fix the tray 2 in the refrigeration cavity 11. In specific implementation, the number of support structures 12 is the same as the number of trays 2, so as to support the trays 2 in a one-to-one correspondence.
[0058] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0059] The above are merely specific embodiments of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
