[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0034] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0035] In order to solve the problem that in the prior art, when a reinforced metal unit is embedded between the rails of a refrigerator liner and a drawer for conducting electricity, the electrical signal cannot be transmitted and potential safety hazards may occur. An embodiment of the present invention provides a refrigeration device.

[0036] like Figure 1-8 As shown, a refrigeration device provided in this embodiment includes a box body 1 having a refrigeration compartment 11, a drawer 2 and a wire assembly 3, wherein the drawer 2 is slidably installed in the refrigeration compartment 11 and has a closed position in which the drawer is stored in the refrigeration compartment 11 and an open position in which the drawer at least partially protrudes out of the refrigeration compartment in the front-rear direction, wherein the wire assembly includes a wire body 31 and an installation unit 32, wherein the installation unit 32 is arranged on the outer side of a side wall of the drawer 2 in the transverse direction, wherein the installation unit 32 includes a wire reel 321, wherein the wire reel 321 is rotatably arranged relative to the drawer, wherein the wire body 31 is wound on the wire reel 321, wherein both ends of the wire body 31 are respectively connected to the drawer 2 and the wall of the refrigeration compartment 11, wherein when the drawer moves from the closed position to the open position, the wire reel 321 is driven to pivot in a first direction, and when the drawer moves from the open position to the closed position, the wire reel 321 is driven to pivot in a second direction, wherein the first direction is opposite to the second direction.

[0037] It should be noted that, in this embodiment, when the cable reel 321 is driven to pivot along the first direction, the cable body 31 can be pulled out from the cable reel 321; and when the cable reel 321 is driven to pivot along the second direction, the cable body 31 can be retracted and wound around the cable reel 321 again.

[0038] The wire body 31 is wound on the wire reel 321, one end of which is connected to the drawer 2, and the other end is connected to the wall of the refrigeration compartment 11, and is configured so that when the wire reel 321 is driven to pivot in a first direction, the wire body 31 can be pulled out from the wire reel 321, and when the wire reel 321 is driven to pivot in a second direction, the wire body 31 can be retracted and wound on the wire reel 321. The specific method of winding the wire body 31 on the wire reel 321 above should be understood by those skilled in the art.

[0039] Here, when the first direction is defined as the clockwise direction, the second direction is the counterclockwise direction; of course, the first direction can also be defined as the counterclockwise direction, and the second direction can be correspondingly set to the clockwise direction. This is not limited in this embodiment.

[0040] Through the above-mentioned arrangement, when the drawer 2 moves from the closed position to the open position, the cable reel 321 is driven to pivot along the first direction, and the wire body 31 is pulled out from the cable reel to ensure that the wire body 31 can connect the wall of the refrigeration compartment 11 and the drawer 2 during this process; when the drawer 2 moves from the open position to the closed position, the cable reel 321 is driven to pivot along the second direction, so that the wire body 31 is retracted and wound around the cable reel 321, so as to prevent the drawer 2 from moving and crushing the wire body 31, thereby causing a safety hazard.

[0041] It should be emphasized that the wire body 31 in this embodiment can be a conductive wire used simply for conducting electricity, or can be a signal wire used for transmitting electrical signals or digital signals.

[0042] Furthermore, if Figure 2-4 As shown, the installation unit 32 includes an installation box 322 connected to the outer side of a side wall of the drawer 2 in the transverse direction. Optionally, the installation box 322 can be installed on the outer side of the left side wall of the drawer 2 in the transverse direction, or on the outer side of the right side wall of the drawer 2 in the transverse direction.

[0043] It should be noted that the installation box has a wire outlet 3221 , and a fixing shaft 3222 is provided on the inner wall of the installation box 322 , and the fixing shaft 3222 is perpendicular to the side wall of the drawer 2 on which the installation box 322 is installed.

[0044] Optionally, the fixing shaft 3222 may be disposed on the inner side of a first wall connecting the installation box 322 and the drawer 2, or may be disposed on the inner side of a second wall opposite to the first wall.

[0045] Furthermore, the cable reel 321 is sleeved with the fixed shaft 3222 through its central sleeve hole 3211 and can pivot relative to the fixed shaft 3222 .

[0046] It can be understood that the cable reel 321 is arranged inside the installation box 322, and the cable body 31 is wound on the cable reel 321 so that most of the cable body 31 is located in the installation box 322. One end of the cable body 31 can extend out of the installation box 322 from the cable outlet 3221, and the other end can pass through the installation box 322 and be connected to the drawer 2. The installation box 322 can protect the cable body 31 located inside it, and the cable body 31 is not easily damaged during the opening and closing of the drawer 2.

[0047] Now turn to Figure 4 The mounting unit 32 also includes a coil spring 323 sleeved on the fixed shaft 3222, and the two ends of the coil spring 323 are respectively connected to the fixed shaft 3222 and the cable reel 321. When the drawer 2 moves from the closed position to the open position, the elastic deformation of the coil spring 323 gradually increases. During this process, the user usually applies a certain pulling force to the drawer 2, and the drawer 2 drives the wire body 31 to drive the cable reel 321 to pivot along the first direction, so that the wire body 31 is pulled out from the cable reel 321.

[0048] When the drawer 2 moves from the open position to the closed position, the elastic deformation of the coil spring 323 gradually decreases, and the elastic potential energy of the coil spring 323 is gradually converted into the kinetic energy of the cable reel 321 connected to the coil spring 323, so as to drive the cable reel 321 to pivot in the second direction, so that the wire body 31 is rewound on the cable reel 321.

[0049] Specifically, if Figure 5 , which shows the general structure of the cable reel 321 in this embodiment, the cable reel 321 includes a reel body 3212, a central hole 3211 is provided at the axis of the reel body 3212, and a wire winding portion 3213 is located in the circumferential direction of the reel body 3212, and the wire winding portion 3213 is used to wind the wire body 31. After the cable reel 321 is sleeved on the fixed shaft 3222, the coil spring 323 can also be sleeved on the fixed shaft 3222, one end of the coil spring 323 is connected to the fixed shaft 3222, and the other end is connected to the reel body 3212 or the wire winding portion 3213.

[0050] Then turn Figure 6 In this embodiment, a mounting groove 111 is provided on the wall of the refrigerating chamber 11, and a connecting column 112 is provided in the mounting groove. Specifically, the wire body 31 is electrically connected to the connecting column 112. This arrangement can ensure the stability of the electrical connection between the wire body 31 and the wall of the refrigerating chamber 11 during the movement of the drawer, and avoid poor contact between the wire body 31 and the wall of the refrigerating chamber 11 due to frequent movement of the drawer 2.

[0051] In some embodiments, the refrigerator further comprises a door body, which is pivotally connected to the box body to open and close the refrigeration compartment. When the door body closes the refrigeration compartment, the drawer is in a closed position stored in the refrigeration compartment. When the drawer needs to be in an open position, the user needs to first open the door body and then pull out the drawer so that the drawer at least partially protrudes out of the refrigeration compartment. The arrangement of the door body is not shown in the drawings of the present invention, but it should be understood by those skilled in the art.

[0052] Preferably, in this embodiment, according to Figure 3 As best shown, the drawer 2 includes a drawer body 21 defining an inner cavity of the drawer and a drawer door 22 attached to the drawer body. In the closed position, the drawer door 22 can directly close the front side of the box body 1.

[0053] According to the specific position of the drawer 2 inside the refrigeration chamber 11, the door body 5 can be arranged above or below the drawer 2; of course, when the drawer 2 is located in the middle position in the vertical direction of the refrigeration chamber 11, the door body 5 can be arranged above and below the drawer 2 respectively.

[0054] It can be understood that the refrigeration compartment 11 has a first portion corresponding to the door body 5, and the door body 5 is pivotally connected to the box body 1 to close the first portion; the refrigeration compartment 11 also has a second portion corresponding to the drawer 2, and the drawer 2 can close the second portion when it is closed. Specifically, the drawer door 22 closes the second portion. Through this arrangement, when the drawer 2 needs to be opened, it is not necessary to open the door body 5 first and then open the drawer, which is convenient for users.

[0055] Furthermore, if Figure 7 As shown, the refrigerator further includes two slide rail assemblies 4 connected to the two side walls of the refrigerating compartment in the transverse direction, wherein each of the slide rail assemblies includes a fixed rail 41 arranged on the side wall of the refrigerating compartment along the front-to-back direction and a sliding rail 42 movable forward and backward on the fixed rail, and the sliding rail 42 is cooperatively arranged on the outer side of the side wall corresponding to the drawer body 21. When the sliding rail 42 slides on the fixed rail 41, the drawer body 41 is driven to move in the refrigerating compartment 11, so that the drawer 2 can be opened or closed.

[0056] Preferably, the slide rail assembly 4 further comprises a brake device 43 for fixing the slide rail 42 relative to the fixed rail 41. Generally speaking, when the drawer 2 is opened, it is necessary to ensure that the slide rail 42 is fixed relative to the fixed rail 41 to keep the drawer 2 in an open state.

[0057] The brake device 43 can generally be configured as a buckle structure. In this embodiment, Figure 7 , 8As shown, the braking device 43 includes at least two supporting protrusions 431 arranged on the lower surface of the sliding rail 42, at least two of the supporting protrusions 431 are arranged at intervals along the front-to-back direction, and the upper surface of the fixed rail 41 is provided with a limiting groove 432 for accommodating the supporting protrusions. When the user opens the drawer 2, the supporting protrusion 431 is engaged in the limiting groove 432, which can limit the position of the drawer 2 in the front-to-back direction to avoid sliding; especially when opening an empty drawer 2, the coil spring 323 is prevented from pulling the cable reel 321 to pull the drawer 2 toward the inside of the refrigeration compartment 11.

[0058] It can be understood that when the drawer 2 needs to be closed, the user applies an upward force to the drawer 2, at which time the sliding rail 42 will pivot upward with a certain part of the rear section as a fulcrum to form a lever, so that the support protrusion 431 moves out of the limit groove 432. Then, a thrust force is applied toward the rear of the drawer 2, which can facilitate the drawer 2 to move backward and finally close.

[0059] Optionally, an inner container opening forward is disposed in the box body 1 , and the inner container defines the refrigeration chamber 11 .

[0060] Preferably, in this embodiment, the refrigeration device is a refrigerator, for example, a single-door upright refrigerator, a double-door upright refrigerator, and the like.

[0061] In summary, the embodiments of the present invention achieve the following technical effects:

[0062] When the drawer 2 moves from the closed position to the open position, the cable reel 321 is driven to pivot in a first direction, and the cable body 31 is pulled out from the cable reel to ensure that the cable body 31 can connect the wall of the refrigeration compartment 11 and the drawer 2 during this process; when the drawer 2 moves from the open position to the closed position, the cable reel 321 is driven to pivot in a second direction, so that the cable body 31 is retracted and wound around the cable reel 321, so as to prevent the drawer 2 from moving and crushing the cable body 31, thereby causing a safety hazard.
