[0040] Currently, during the use of refrigeration units, condensation easily forms on the door frame due to the temperature difference between the inside and outside, such as in refrigerators. Condensation on the refrigerator door frame severely affects the user's ability to open and close the door. To solve this problem, the common technology involves installing heating wires on the door frame, connecting them to a wiring harness on the refrigerator body for power transmission, and then controlling the power supply to the heating wires via a control module. However, because the refrigerator door and body need to be opened and closed, laying the wiring harness between them is quite difficult.

[0041] Based on this, the present invention proposes a refrigeration device. The aim is to solve the problem of difficult wiring harness layout in existing refrigeration devices. Among other things, Figures 1 to 9 A schematic diagram of the refrigeration device provided by this utility model.

[0042] Please see Figures 1 to 4 In one embodiment of this utility model, the refrigeration device 100 includes a housing 1, a door 2, a mounting component 3, and a wireless power transmission structure 4. The door 2 is disposed on the housing 1 and includes a door body 21 and a cover 22 disposed on the door body 21. An electric heating part 23 is disposed on the cover 22. The mounting component 3 is disposed on the housing 1 and is disposed corresponding to the cover 22. The wireless power transmission structure 4 includes a wireless receiving part 41 and a wireless power transmission part 42 that are wirelessly connected. The wireless receiving part 41 is disposed on the cover 22 and is electrically connected to the electric heating part 23. The wireless power transmission part 42 is disposed on the mounting component 3 and is disposed corresponding to the wireless receiving part 41.

[0043] The technical solution of this utility model involves setting up a housing 1 to install the door 2 and the mounting component 3. The door 2, together with the housing 1, forms a space capable of holding items. An electric heating unit 23 is provided to heat the cover 22 of the door 2, reducing the probability of condensation on the cover 22. The mounting component 3 is provided to install the wireless charging unit 41, allowing the wireless charging unit 41 to be positioned corresponding to the cover 22. The wireless power transmission unit 42 is provided to connect with the electrical circuits on the housing 1. The power supply is connected to the wireless power receiver 41 to supply power to the electric heating unit 23, enabling the electric heating unit 23 to heat the cover 22. Thus, by providing power to the electric heating unit 23 through the wireless power receiver 41, which can wirelessly transmit power, the power supply of the housing 1 and the electric heating unit 23 are not connected through a wire harness. This reduces the difficulty of wiring and solves the problem of difficult wiring in the existing refrigeration device 100.

[0044] It should be noted that the housing 1 is the main structure, primarily used to form a closed space for storing items together with the door 2, thereby extending the storage time of the items. The mounting component 3 is mainly used to install the wireless power connector 41, and its material can vary. The mounting component 3 can be made of metals such as iron and steel, inorganic non-metallic materials such as ceramics, or polymer materials such as plastics; this invention does not limit its material. Furthermore, the mounting component 3 can have various shapes, such as rectangular or rhomboid; this invention does not limit its shape. The electric heating element 23 can be of various types, such as an electric heating wire or an electric heating plate; this invention does not limit its material.

[0045] It should also be noted that the wireless receiving unit 41 and the wireless transmitting unit 42 are devices that cooperate to transmit power wirelessly. This is a structure that can transmit power without a direct electrical connection, and it can be achieved through electromagnetic induction, magnetic resonance coupling, or radio waves. The wireless transmitting unit 42 is connected to the power supply on the housing 1 via a wiring harness to transmit electrical energy to the wireless receiving unit 41. The wireless receiving unit 41 receives the electrical energy transmitted by the wireless transmitting unit 42 and converts it into a stable DC output to power the electric heating unit 23, enabling the electric heating unit 23 to heat the cover 22 and reduce the possibility of condensation on the cover 22.

[0046] In one embodiment of this utility model, please refer to Figures 6 to 9 Along the arrangement direction of the mounting member 3 and the cover 22, the distance between the wireless receiving part 41 and the wireless transmission part 42 is L1, where L1≤10mm. Since the greater the distance between the wireless receiving part 41 and the wireless transmission part 42, the less stable the connection between them, L1≤10mm can effectively reduce the possibility of wireless transmission failure due to excessive distance between them, thereby helping to improve the stability of the wireless connection between the wireless transmission structure 4.

[0047] In one embodiment of this utility model, please refer to Figure 8 and Figure 9The offset between the center of the wireless receiving part 41 and the center of the wireless transmission part 42 is L2, where 0≤L2≤5mm. Since the larger the center offset between the wireless receiving part 41 and the wireless transmission part 42, the less stable the connection between the wireless receiving part 41 and the wireless transmission part 42, 0≤L2≤5mm can effectively reduce the possibility of wireless power transmission failure due to excessive center offset between the wireless receiving part 41 and the wireless transmission part 42, thereby helping to improve the stability of the wireless connection between the wireless power transmission structures 4.

[0048] Since the door 2 needs to be opened during use, if the wireless power transmission structure 4 is located at the end of the door 2 away from the rotating end, when the door 2 is opened, the wireless receiving part 41 will be too far from the wireless power transmission part 42, which may cause the power transmission part to disconnect from the wireless receiving part 41, resulting in wireless power transmission failure. In this embodiment, please refer to... Figures 3 to 5 The door body 2 has a rotating end in its width direction, which is rotatably mounted on the mounting member 3. The wireless power transmission structure 4 is disposed on the rotating end. In this way, by placing the mounting member 3 on the rotating end of the door body 2, the wireless power receiving part 41 is as close as possible to the wireless power transmission part 42 when the door body 2 is open, reducing the risk of disconnection between the wireless power transmission part 42 and the wireless power receiving part 41. This allows the wireless power transmission structure 4 to maintain connection regardless of whether the door body 2 is in the open or closed state, thereby helping to improve the stability of the connection of the wireless power transmission structure 4.

[0049] It should be noted that there are various ways to connect the mounting component 3 to the housing 1. The mounting component 3 can be installed to the housing 1 by welding or by bolts, etc., and this utility model does not limit this. Furthermore, in this embodiment, the mounting component 3 is detachably installed to the housing 1. Thus, the detachable connection structure is adopted to facilitate the installation and removal of the mounting component 3, making it easy to adjust or replace the mounting component 3 as needed, and facilitating subsequent maintenance or replacement.

[0050] In one embodiment of this utility model, one of the rotating ends of the mounting member 3 and the door body 2 is provided with a rotating shaft 51, and the other is provided with a rotating sleeve 52 of the rotating shaft 51. The rotating shaft 51 is rotatably installed in the rotating sleeve 52. Thus, by setting the rotating shaft 51 and the rotating sleeve 52 to cooperate with each other, the door body 2 can be rotatably installed on the housing 1. Furthermore, the rotating shaft 51 is provided on the mounting member 3, and the rotating sleeve 52 is provided on the door body 2, so as to make full use of the space of the door body 2 and reduce the space occupied by the mounting member 3, thereby helping to improve the space utilization rate of the refrigeration device 100.

[0051] Furthermore, the cover 22 includes a cover body 221 and a fixing part 222 detachably installed on the cover body 221. The rotating sleeve 52 is provided on the fixing part 222. Thus, by providing the fixing part 222, the rotating sleeve 52 can be provided so that the door 2 can be rotatably installed on the mounting member 3. At the same time, the detachable structure allows for the installation and removal of the fixing part 222, which can be adjusted as needed and is convenient for maintenance or replacement.

[0052] For ease of installation of the wireless power transmission unit 42, please refer to [reference needed] in this embodiment. Figure 3 The mounting component 3 is provided with a mounting groove 31, and the wireless power transmission unit 42 is disposed in the mounting groove 31. In this way, by providing the mounting groove 31, on the one hand, the position of the wireless power transmission unit 42 can be located on the mounting component 3, which is conducive to the quick installation of the wireless power transmission unit 42 on the mounting component 3. On the other hand, the thickness of the mounting component 3 can be used to accommodate the wireless power transmission unit 42, which can effectively reduce the space occupied by the wireless power transmission unit 42 and improve the space utilization rate of the cooling device 100.

[0053] It should be noted that there are various ways to connect the wireless power transmission unit 42 to the mounting component 3. The wireless power transmission unit 42 can be fixed to the mounting component 3 by adhesive bonding or by snap-fitting, etc. This utility model does not limit this.

[0054] In one embodiment of this utility model, please refer to Figure 4 and Figure 5 The wireless charging unit 41 is disposed on the side of the cover 22 facing away from the mounting member 3, so as to hide the wireless charging unit 41 inside the door body 2, which can both protect the wireless charging unit 41 and improve the appearance of the door body 2. Of course, in other embodiments, the wireless charging unit 41 may also be disposed on the side of the cover 22 facing the mounting member 3, and this utility model does not limit this.

[0055] It should be noted that there are various ways to connect the wireless charging part 41 to the cover 22. The wireless charging part 41 can be fixed to the cover 22 by adhesive bonding, or by snap-fit, etc. This utility model does not limit this. Furthermore, there are various ways to position the wireless charging part 41 on the cover 22. The wireless charging part 41 can be located on the side of the cover 22, or it can be embedded in the cover 22, etc. This utility model does not limit this.

[0056] In one embodiment of this utility model, please refer to Figure 1 and Figure 2 Two door bodies 2 are provided, each consisting of an upper door body 24 and a lower door body 25 spaced apart. Two wireless charging units 41 are provided, one on the cover 22 of the upper door body 24 and the other on the cover 22 of the lower door body 25. Thus, by providing the upper door body 24 and the lower door body 25, items can be stored separately. At the same time, by providing the two wireless charging units 41, the lower door body 25 and the cover 22 of the upper door body 24 can be heated separately, reducing the risk of condensation on the upper door body 24 and the lower door body 25.

[0057] It should be noted that the cover 22 provided on the upper door body 24 can be of various types. It can be a cover 22 provided on the upper end of the upper door body 24 or a cover 22 provided on the lower end of the upper door body. This utility model does not limit this. Similarly, the cover provided on the lower door body 25 can be a cover 22 provided on the upper end of the lower door body 25 or a cover 22 provided on the lower end of the lower door body. This utility model does not limit this.

[0058] Furthermore, in order to heat the cover 22 of the lower door body 25 and the upper door body 24, in this embodiment, please refer to... Figure 8 and Figure 9 A cover 22 located on the upper door body 24 is situated at the lower end of the upper door body 24, and a cover 22 located on the lower door body 25 is situated at the upper end of the lower door body 25. The mounting member 3 is positioned between the upper door body 24 and the lower door body 25. The wireless power transmission unit 42 is electrically connected to two wireless power receiving units 41. Thus, by providing power to both wireless power receiving units 41 simultaneously through one wireless power transmission unit 42, each wireless power receiving unit 41 can provide power to its corresponding electric heating unit 23, enabling the electric heating unit 23 to heat the cover 22. Of course, in other embodiments, power can also be supplied to two wireless power receiving units 41 separately, as long as it allows power to both wireless power receiving units 41; this invention does not limit this.

[0059] In one embodiment of this utility model, in the vertical direction, the center of the wireless power transmission unit 42 is set to correspond to the center of one of the wireless power receiving units 41. Since the temperature is different above and below the box 1, the risk of condensation above and below the box 1 will also be different. Therefore, the center of the wireless power transmission unit 42 is set to correspond to one of the wireless power receiving units 41 to ensure that the wireless power transmission unit 42 is stably connected to the corresponding wireless power receiving unit 41 and reduce the probability of condensation on the corresponding door 2.

[0060] It should be noted that the center of the wireless power transmission unit 42 is set to correspond to the center of one of the wireless power receiving units 41, which means that the center of the wireless power receiving unit is close to the center of one of the wireless power receiving units 41, or aligned with the center of one of the wireless power receiving units 41.

[0061] In one embodiment of this utility model, the refrigeration device 100 includes a refrigerator, which has a refrigerator compartment and a freezer compartment. The upper door 24 corresponds to the refrigerator compartment, and the lower door 25 corresponds to the freezer compartment. Since cold air is heavier than hot air, it sinks. When the refrigerator compartment is located at the top, the cold air naturally flows downward and enters the freezer compartment. This can more effectively utilize the natural convection inside the refrigerator to maintain the temperature, reduce the workload of the compressor, and thus help save energy. At the same time, the refrigerator compartment is usually opened more frequently than the freezer compartment during use. Therefore, placing the refrigerator compartment at the top allows users to easily retrieve food without bending over, which is more ergonomic and helps improve the convenience and comfort of use.

[0062] Furthermore, the center of the wireless power transmission unit 42 is aligned with the center of the wireless power receiving unit 41 located on the lower door body 25, so as to improve the stability of the wireless power transmission structure connection of the lower door body 25, reduce the probability of power transmission failure between the wireless power receiving unit 41 and the wireless power transmission unit 42 located on the lower door body 25, and thus help reduce the risk of condensation on the lower door body 25.

[0063] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
