[0028] The refrigeration device may include a housing and a shelf. A refrigeration compartment is provided in the housing for accommodating food. The shelf is arranged in the refrigeration compartment to separate the refrigeration compartment into multiple layers, thereby facilitating the placement of food and improving the space utilization rate of the refrigeration compartment.

[0029] When food is refrigerated in a refrigeration room, some of the food will emit peculiar smell, which will diffuse in the refrigeration room, causing the odor to cross with other foods and affect the consumption of the food.

[0030] Some foods that emit odors may include: stinky tofu, durian, etc.

[0031] It is understandable that food is generally placed in a container with an open top. When the food and the container are placed on the shelf together, the plastic wrap can cover and block the opening of the container to prevent the spread of peculiar smell.

[0032] When the food itself is partially opened, the plastic wrap can also cover and block the opening of the food to keep the food fresh and prevent the odor in the food from diffusing into the refrigeration room from the opening.

The fresh-keeping structure 300 may be received in the receiving cavity 240.

[0051] When the fresh-keeping structure 300 needs to be inspected, repaired or replaced, the user can open the end cover 220 to open the accommodating cavity 240 , thereby facilitating the inspection, replacement or repair of the fresh-keeping structure 300 .

[0052] See also Figure 3 to Figure 4 In this embodiment, the accommodating cavity 240 may extend in the front-to-back direction. The front and / or rear of the shelf 200 may be open so as to be able to enclose the accommodating cavity 240 with the end cover 220 .

[0053] The upper surface of the shelf 200 is provided with a communication port 250 to communicate with the accommodating cavity 240. The communication port 250 extends in the front-to-back direction, so that the cling film 320 can be expanded and contracted through the communication port 250, and can ensure the stability of the cling film 320 during contraction and prevent the cling film 320 from tilting during contraction.

[0054] In some embodiments, the connecting port 250 is located in the middle of the shelf 200 so that the second end can be limited by the hook 112 on the left or right side, respectively, so as to cover the food 40 on the left or right side of the shelf 200, respectively, thereby improving the space utilization of the refrigeration chamber 110 and effectively preventing the food 40 from tainting the food 40.

[0055] In some embodiments, the communication port 250 is located on the left side of the shelf 200, and the hook 112 is located on the right side wall of the refrigeration chamber 110, so that the plastic wrap 320 can cover the multiple foods 40 on the shelf 200, thereby effectively preventing the food 40 from tainting the food 40. In some embodiments, the communication port 250 is located on the right side of the shelf 200, and the hook 112 is located on the left side wall of the refrigeration chamber 110, so as to prevent the food 40 from tainting the food 40.

[0056] In other embodiments, the accommodating cavity 240 and the communicating opening 250 may extend in the left-right direction, and the second end of the cling film 320 may be positioned forwardly on the front side or the rear side of the shelf 200 .

[0057] See also Figure 3 to Figure 4 In this embodiment, a sealing strip (not shown) may be provided between the end cover 220 and the layer frame body 210. The sealing strip can seal the gap between the layer frame body 210 and the end cover 220, thereby ensuring the sealing performance of the accommodating cavity 240.

[0058] In this embodiment, a sealing protrusion 223 may be provided on one side of the end cover 220 facing the accommodating cavity 240 relative to the accommodating cavity 240. The sealing protrusion 223 can extend into the accommodating cavity 240, and the peripheral side wall of the sealing protrusion 223 can abut against the peripheral side wall of the accommodating cavity 240, thereby improving the sealing performance of the accommodating cavity 240.

[0059] In some embodiments, the sealing protrusion 223 may be arranged in a ring shape. In other embodiments, the sealing protrusion 223 may extend in a rectangular shape on a side wall of the end cover 220 facing the accommodating cavity 240 .

[0060] See also Figure 3 to Figure 4 In this embodiment, a fixed shaft 260 may be further provided in the receiving chamber 240 of the shelf 200. The fixed shaft 260 extends along the extension direction of the receiving chamber 240 to facilitate the curling of the elastic member 310, thereby realizing the expansion and contraction of the cling film 320.

[0061] When the shelf 200 is provided with end covers 220 at both ends of the accommodating cavity 240 , both ends of the fixed shaft 260 can be detachably connected to the end covers 220 , so as to facilitate the fixing and removal of the fixed shaft 260 .

[0062] A limiting protrusion 221 may be convexly provided on one side of the end cover 220 facing the layer frame body 210. The limiting protrusion 221 may extend into the accommodating cavity 240. A first fixing groove 222 may be concavely provided on a side wall of the limiting protrusion 221 facing the center of the accommodating cavity 240. The first fixing groove 222 can accommodate and limit the fixed shaft 260, so that the end cover 220 can support and limit the fixed shaft 260, and ensure the stability and reliability of the fixed shaft 260.

[0063] The limiting protrusion 221 may be provided with a first spline groove 2221 on the inner peripheral wall of the first fixed groove 222, and a second spline groove (not shown in the figure) may be provided on the peripheral side wall of one end of the fixed shaft 260 relative to the first spline groove 2221. When the fixed shaft 260 extends into the first fixed groove 222, the limiting protrusion 221 is spline-connected with the fixed shaft 260 through the first spline groove 2221 and the second spline groove to prevent the fixed shaft 260 from rotating around its own axis relative to the end cover 220, thereby ensuring the stability and reliability of the fixed shaft 260.

[0064] In some embodiments, the first spline groove 2221 may extend along the axial direction of the fixed shaft 260 toward the center of the fixed shaft 260 to facilitate the fixed shaft 260 and the spline to move into and out of the first fixed groove 222 .

[0065] In other embodiments, the front end of the shelf 200 at the accommodating cavity 240 may be opened to cover the end cover 220, the front end of the fixed shaft 260 may be detachably connected to the end cover 220, and the rear end of the fixed shaft 260 may be detachably connected to the rear end wall of the accommodating cavity 240. In other embodiments, the rear end of the shelf 200 at the accommodating cavity 240 may be opened to cover the end cover 220, the rear end of the fixed shaft 260 may be detachably connected to the end cover 220, and the front end of the fixed shaft 260 may be detachably connected to the front end wall of the accommodating cavity 240.

[0066] When an end cover 220 is provided at one end of the accommodating cavity 240 and the other end is closed, a second fixing groove (not shown in the figure) is recessed on the end wall of the accommodating cavity 240 away from the end cover 220. The second fixing groove can accommodate one end of the fixed shaft 260, so that the second fixing groove and the first fixing groove 222 can jointly accommodate and limit the fixed shaft 260 to ensure the stability and reliability of the fixed shaft 260.

[0067] See also Figure 3 to Figure 4 In this embodiment, the refrigeration device may further include a fresh-keeping structure 300. The fresh-keeping structure 300 can be accommodated in the accommodating cavity 240. The fresh-keeping structure 300 can cover the food 40 to achieve functions such as fresh-keeping and anti-odor.

[0068] The preservation structure 300 may include an elastic member 310 and a preservation film 320. One end of the elastic member 310 may be connected to the fixed shaft 260, and the other end of the elastic member 310 may be wound around the fixed shaft 260 and connected to the first end to drive the preservation film 320 to be wound around the fixed shaft 260.

[0069] When the user uses the cling film 320, the user pulls the second end of the cling film 320, the elastic member 310 is stretched out after being stressed, and the second end of the cling film 320 moves toward the hook 112 and is limited on the hook 112. During the unfolding process of the cling film 320, the cling film 320 can cover the food 40, which can keep the food 40 fresh on one hand, and prevent the odor emitted by the food 40 from spreading in the refrigeration chamber 110 on the other hand.

[0070] When the user has finished using the refrigeration device, the user pulls the second end to separate the second end from the hook 112, and the elastic member 310 contracts, so that the cling film 320 shrinks into the accommodating cavity 240 under the action of the elastic member 310, thereby facilitating multiple uses of the cling film 320 and reducing the use cost of the refrigeration equipment.

[0071] In this embodiment, the elastic member 310 includes a fixed end and a telescopic end. The fixed end can be connected to the fixed shaft 260. The telescopic end can be connected to the first end. The telescopic end can be extended or retracted relative to the fixed end, so that the cling film 320 can be switched between the expanded state and the retracted state.

[0072] In some embodiments, the elastic member 310 can extend along the axial direction of the fixed shaft 260 so that the telescopic end of the elastic member 310 can be connected to both sides of the first end. During the winding process of the cling film 320, the telescopic end is connected to both sides of the first end to ensure that the first end of the cling film 320 is stably wound on the fixed shaft 260, preventing the cling film 320 from being wound obliquely and preventing the cling film 320 from being wound misaligned.

[0073] In some embodiments, the elastic member 310 is a spiral spring. The spiral spring is sleeved on the fixed shaft 260. The fixed end of the spiral spring is fixed on the fixed shaft 260, and the telescopic end of the spiral spring is connected to the first end.

[0074] The spiral spring extends along the axial direction of the fixed shaft 260. In the axial direction of the fixed shaft 260, the length of the spiral spring is greater than or equal to the length of the cling film 320, so that the first end is attached to and limited on the telescopic end of the spiral spring, ensuring that the cling film 320 rotates smoothly and stably around the axis of the fixed shaft 260, preventing the cling film 320 from tilting, curling, and misalignment, thereby improving the safety, reliability and stability of the preservation structure 300.

[0075] See also Figure 3 to Figure 4 In this embodiment, the cling film 320 may include a first end and a second end that are arranged opposite to each other, the first end is connected to the elastic member 310 in the accommodating cavity 240, and the second end can extend out of the shelf 200 through the connecting port 250.

[0076] A handle 330 may be provided on the second end portion relative to the hook 112. When the preservation structure 300 is in the unfolded state, the handle 330 moves and engages with the hook 112 on the side wall of the refrigeration compartment 110. When the preservation structure 300 is in the retracted state, the handle 330 can abut against the upper surface of the shelf 200, so that the user can pull the handle 330.

[0077] In some embodiments, the handle 330 may extend in the forward direction so that the handle 330 can be engaged with the plurality of hooks 112 on the side wall of the refrigeration compartment 110 , thereby improving the connection stability between the handle 330 and the hooks 112 .

[0078] In this embodiment, a disinfectant layer (not shown in the figure) is provided in the accommodating cavity 240, and the disinfectant layer can infiltrate at least a portion of the cling film 320, so that when the cling film 320 is in a contracted state, the disinfectant layer can disinfect the cling film 320, thereby facilitating multiple uses of the cling film 320.

[0079] See also Figures 1 to 4In this embodiment, when the user uses the refrigeration equipment to refrigerate and preserve food 40, the food 40 is placed on the shelf 200, and then the handle 330 is pulled toward the hook 112 adjacent to the food 40. The handle 330 drives the plastic wrap 320 to unfold through the second end, so that the plastic wrap 320 switches from the contracted state to the unfolded state.

[0080] When the cling film 320 is in the unfolded state, the handle 330 is engaged with the hook 112, and the cling film 320 can cover the upper end of the food 40, thereby realizing the functions of preserving the food 40 and preventing odor contamination. The elastic member 310 absorbs part of the pulling force to convert it into elastic potential energy.

[0081] When the user needs to take out the food 40, the handle 330 is separated from the hook 112, and the elastic member 310 converts the elastic potential energy into an elastic tension on the first end of the cling film 320, so that the cling film 320 can switch from the expanded state to the contracted state under the action of the elastic tension.

[0082] When the cling film 320 switches to the contracted state, the cling film 320 contracts back into the accommodating cavity 240 , and the handle 330 abuts against and is limited to the upper surface of the shelf 200 , thereby facilitating the user to recycle the cling film 320 later.

[0083] The utility model shelf 200 also provides another embodiment structure:

[0084] In the horizontal plane, the accommodating cavity 240 in the shelf 200 can be arranged in a rectangular shape. The connecting port 250 is connected to one side of the accommodating cavity 240. The cling film 320 is located in the accommodating cavity 240 and is horizontally extended. The first end of the cling film 320 is connected to the accommodating cavity 240 through the elastic member 310, and the second end of the cling film 320 is limited to the upper side of the shelf 200 through the handle 330.

[0085] When the user uses the preservation structure 300, the user pulls the handle 330 to stretch the elastic member 310 so that the second end of the preservation film 320 can be limited on the hook 112 through the handle 330, so that the preservation film 320 can cover the food 40, keep the food 40 fresh and prevent the food 40 from odor transfer.

[0086] In some embodiments, the elastic member 310 may be a tension spring.
