[0001] The present invention relates to the field of refrigeration and freezing technology, and in particular to a magnetic field component for refrigeration equipment and the refrigeration equipment. Background Art

[0002] Refrigerators are household appliances that can store food and other items in cold storage. As people's living standards improve, higher requirements are placed on the freshness-keeping effect of refrigerators. Studies have found that applying a magnetic field to food can play a good auxiliary role in the storage of food, so that the food can better maintain its quality whether it is refrigerated or frozen.

[0003] However, after the existing magnetic field device is fixed in the compartment of the refrigerator, it can only generate a magnetic field within a fixed range in the compartment, and is not flexible enough to use. Summary of the invention

[0004] An object of the present invention is to provide a magnetic field assembly for a refrigeration device and a refrigeration device that can solve any of the above problems.

[0005] A further object of the present invention is to make the movement of the magnetic sheet more stable.

[0006] In particular, the present invention provides a magnetic field assembly for a refrigeration device, the magnetic field assembly is used to be arranged in a storage compartment of the refrigeration device to generate a magnetic field in a food storage area of ​​the storage compartment, and the magnetic field assembly includes:

[0007] Axle; and

[0008] The magnetic sheet is used to generate a magnetic field. The magnetic sheet is wound around a shaft, and can be rolled up or unfolded relative to the shaft to change the coverage of the magnetic sheet on the area where the food is placed.

[0009] Optionally, the magnetic field assembly further includes a mounting frame, the shaft rod is disposed on the mounting frame, and the magnetic field assembly is fixed in the storage compartment via the mounting frame.

[0010] Optionally, the magnetic field assembly further includes a guide member, which is used to define a moving path of the magnetic sheet so that the magnetic sheet can be rolled up or unfolded along the moving path.

[0011] Optionally, the guiding member comprises:

[0012] A support rod, the support rod and the shaft rod are respectively arranged on two opposite sides of the mounting frame; and

[0013] The transmission belt is sleeved on the shaft rod and the support rod, and the magnetic sheet is fixedly connected to the transmission belt, so that the magnetic sheet can be rolled up or unfolded along the moving path of the transmission belt.

[0014] Optionally, the guiding member includes two transmission belts, which are respectively arranged at two ends of the shaft rod, and the magnetic sheet is fixedly connected to the two transmission belts.

[0015] Optionally, the magnetic field assembly includes a connecting rod, the connecting rod is fixedly connected to the transmission belt, and the connecting rod is connected to the side of the magnetic sheet, so that the magnetic sheet is connected to the transmission belt through the connecting rod.

[0016] Optionally, the magnetic field assembly includes a driving device, and the driving device is used to drive the magnetic sheet to reel in or unfold.

[0017] Optionally, the driving device is connected to the shaft to drive the shaft to rotate, thereby causing the magnetic sheet to be rolled up or unfolded.

[0018] In another aspect of the present invention, a refrigeration device is provided, comprising:

[0019] a box body, the box body forming a storage compartment; and

[0020] According to any one of the above magnetic field components, the magnetic field component is arranged in the storage compartment to generate a magnetic field in the food placement area of ​​the storage compartment.

[0021] Optionally, the refrigeration device includes a partition plate, which is arranged in the food placement area and is used to divide the food placement area into two areas arranged along the unfolding direction of the magnetic sheet, and the partition plate is slidably arranged along the unfolding direction of the magnetic sheet.

[0022] The magnetic field assembly of the present invention winds the magnetic sheet around the shaft so that the magnetic sheet can be rolled up or unfolded relative to the shaft. Depending on the degree of unfolding of the magnetic sheet, the range that the magnetic sheet can cover will also change, that is, the range of action of the magnetic field generated by the magnetic sheet can change. Therefore, by rolling up or unfolding the magnetic sheet, the range of action of the magnetic field generated by the magnetic sheet in the food placement area of ​​the storage room can be adjusted, so that the magnetic field assembly can be used flexibly. For example, when there are fewer ingredients, the magnetic sheet can be adjusted according to the placement of the ingredients so that the magnetic field value of the magnetic sheet acts on the placement of the ingredients, or when the user wants to use the magnetic field to store part of the ingredients and not use the magnetic field to store part of the ingredients, the magnetic sheet can be adjusted to cover part of the ingredients that want to be stored using the magnetic field, thereby improving the user experience.

[0023] Furthermore, the magnetic field assembly of the present invention is provided with a support rod and a transmission belt, and the magnetic sheet is fixedly connected to the transmission belt, so that the moving path of the magnetic sheet is limited to be consistent with the moving path of the transmission belt, thereby limiting the moving path of the magnetic sheet, so that the magnetic sheet can be unfolded according to the fixed moving path, making the movement of the magnetic sheet more stable. In other words, it is ensured that the unfolded state of the magnetic sheet is fixed, and the magnetic sheet is prevented from tilting at a large angle after unfolding, which affects the relative position relationship with the food placement area, thereby avoiding affecting the magnetic field effect. At the same time, the magnetic sheet is fixedly connected to the transmission belt, so that after the magnetic sheet is in an unfolded state, it can be fixed in this state by the transmission belt, and the magnetic sheet is prevented from moving.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] like Figure 1 As shown, in one embodiment, the refrigeration device includes a housing 100 and a magnetic field assembly 200. The housing 100 is formed with a storage compartment 101. The magnetic field assembly 200 is arranged in the storage compartment 101 to generate a magnetic field in the food storage area of ​​the storage compartment 101. Specifically, the refrigeration device of this embodiment is a refrigerator, and the refrigerator includes a housing 100 and a door body (not shown in the figure), and the door body is used to open and close the storage compartment 101 of the housing 100. Generally speaking, a refrigerator usually has multiple storage compartments, such as a refrigerated storage compartment, a frozen storage compartment, a variable temperature storage compartment, and the like. Figure 1 Only one storage compartment 101 of the refrigerator is illustrated, and the storage compartment 101 can be any storage compartment that can be set in the refrigerator. For the refrigerator of the present application, those skilled in the art can configure the number, function and layout of the specific storage compartments according to the needs, and the magnetic field assembly 200 can be set in one or more of the storage compartments.

[0037] Reference Figures 1 to 4As shown, the magnetic field assembly 200 includes a shaft 210 and a magnetic sheet 220. The magnetic sheet 220 is used to generate a magnetic field. The magnetic sheet 220 is wound around the shaft 210, so as to be rolled up or unfolded relative to the shaft 210 to change the coverage of the magnetic sheet 220 on the food placement area. Specifically, the magnetic sheet 220 is a flexible structure. For example, the magnetic sheet 220 is made of a composite material of ferrite magnetic powder and synthetic rubber, and has the ability to deform while being able to generate a magnetic field. The magnetic sheet 220 is wound around the shaft 210, and together with the shaft 210, it forms a rolling curtain structure. When the magnetic sheet 220 is completely rolled up on the shaft 210, the magnetic sheet 220 is generally cylindrical in shape. In the process of unfolding the magnetic sheet 220 relative to the shaft 210, as the part of the magnetic sheet 220 unfolded into a plane continues to increase, the diameter of the cylindrical part of the magnetic sheet 220 continues to decrease. The magnetic sheet 220 unfolded into a plane partially covers the food placement area, and a differential magnetic field is generated in the food placement area.

[0038] In the solution of this embodiment, by winding the magnetic sheet 220 on the shaft 210, the magnetic sheet 220 can be rolled up or unfolded relative to the shaft 210. According to the degree of unfolding of the magnetic sheet 220, the range that the magnetic sheet 220 can cover will also change, that is, the range of action of the magnetic field generated by the magnetic sheet 220 can change. Therefore, by rolling up or unfolding the magnetic sheet 220, the range of action of the magnetic field generated by the magnetic sheet 220 in the food placement area in the storage room can be adjusted, so that the magnetic field component can be used flexibly. For example, when there are fewer ingredients, the magnetic sheet 220 can be adjusted according to the placement position of the ingredients so that the magnetic field value of the magnetic sheet 220 acts on the placement position of the ingredients, or when the user wants to use the magnetic field to store part of the ingredients and not use the magnetic field to store part of the ingredients, the magnetic sheet 220 can be adjusted to cover part of the ingredients that want to be stored using the magnetic field, thereby improving the user's experience.

[0039] like Figures 1 to 4 As shown, the magnetic field assembly 200 also includes a mounting frame 230, and the shaft 210 is arranged on the mounting frame 230. The magnetic field assembly 200 is fixed in the storage compartment 101 via the mounting frame 230. Specifically, the mounting frame 230 is a square frame formed by four side panels, and the four side panels surround a square area. The two ends of the shaft 210 are respectively connected to the two opposite side panels of the mounting frame 230. Specifically, the two ends of the shaft 210 pass through the two opposite side panels of the mounting frame 230 and are connected to the mounting frame 230, so that the end of the shaft 210 is located outside the square area surrounded by the mounting frame 230, and the middle part of the shaft 210 is located in the square area surrounded by the mounting frame 230. And the size of the shaft 210 located outside the square area is larger than the size of the part passing through the mounting frame 230, and the size of the part located inside the square area is larger than the size of the part passing through the mounting frame 230.

[0040] It should be noted that the shaft 210 and the mounting frame 230 can be fixedly connected or rotatably connected (the shaft 210 can rotate around its own axis). In addition, the shaft 210 can be an integrally formed structure, or it can be composed of a main body and a component sleeved on the main body, the diameter of the component sleeved on the main body is larger than the size of the opening of the mounting frame for the shaft to pass through, that is, the component sleeved on the main body constitutes the part of the shaft located outside the square area and the part located inside the square area.

[0041] It should be noted that, in some other embodiments, the size of the portion of the shaft rod located inside the square area may also be equal to the size of the portion of the shaft rod passing through the mounting frame.

[0042] Continue to refer to Figures 1 to 4 As shown, the magnetic sheet 220 is wound around the portion of the shaft 210 located in the square area surrounded by the mounting frame 230, and can be rolled up or unfolded relative to the shaft 210 in the square area. Connectors 231 are provided on both sides of the mounting frame 230, and the mounting frame 230 is connected to the box 100 through the connectors 231, so that the magnetic field assembly 200 is connected to the box 100 as a whole.

[0043] By setting the shaft 210 on the mounting frame 230, the magnetic field assembly 200 is fixed in the storage compartment 101 by the mounting frame 230. Compared with fixing in the storage compartment 101 by the shaft 210, the installation method of the magnetic field assembly 200 is simpler and more flexible.

[0044] It should be noted that in some other embodiments, the mounting frame may not be provided, and the shaft rod is directly connected to the box body.

[0045] like Figures 1 to 4 As shown, further, the magnetic field assembly 200 also includes a guide member, which is used to limit the movable path of the magnetic sheet 220 so that the magnetic sheet 220 can be rolled up or unfolded along the movable path. The guide member includes a support rod 240 and a transmission belt 250. The support rod 240 and the shaft rod 210 are respectively arranged on opposite sides of the mounting frame 230. The transmission belt 250 is sleeved on the shaft rod 210 and the support rod 240, and the magnetic sheet 220 is fixedly connected to the transmission belt 250, so that the magnetic sheet 220 can be rolled up or unfolded along the movable path of the transmission belt 250. Specifically, the guide member includes two transmission belts 250, and the two transmission belts 250 are respectively arranged at both ends of the shaft rod 210, and the magnetic sheet 220 is fixedly connected to the two transmission belts 250.

[0046] like Figure 3 and Figure 4As shown, specifically, the support rod 240 is close to the left side of the mounting frame 230, and the shaft rod 210 is close to the right side of the mounting frame 230. The support rod 240 has the same structure as the shaft rod 210, and is installed on the mounting frame 230 in the same manner. That is, the end of the support rod 240 is located outside the square area surrounded by the mounting frame 230, and the middle of the support rod 240 is located within the square area surrounded by the mounting frame 230. The transmission belt 250 is sleeved on the ends of the support rod 240 and the shaft rod 210 located outside the square area. Figure 3 and Figure 4 As shown, one transmission belt 250 is sleeved on the upper ends of the support rod 240 and the shaft rod 210 , and another transmission belt 250 is sleeved on the lower ends of the support rod 240 and the shaft rod 210 .

[0047] Reference Figures 2 to 4 As shown, further, the magnetic field assembly 200 includes a connecting rod 260, the connecting rod 260 is fixedly connected to the transmission belt 250, and the connecting rod 260 is connected to the side of the magnetic sheet 220, so that the magnetic sheet 220 is connected to the transmission belt 250 through the connecting rod 260. Specifically, the two ends of the connecting rod 260 are fixedly connected to the two transmission belts 250 respectively.

[0048] Specifically, the mounting frame 230 is provided with an escape groove 232, and the position of the escape groove 232 corresponds to a part of the transmission belt 250. The end of the connecting rod 260 passes through the escape groove 232 and is fixedly connected to the transmission belt 250, and the part of the connecting rod 260 located in the square area is connected to the side of the magnetic sheet 220. The mounting frame 230 is provided with two escape grooves 232, and the two ends of the connecting rod 260 are respectively connected to the two transmission belts 250. Because the magnetic sheet 220 is fixedly connected to the transmission belt 250, the moving path of the magnetic sheet 220 during winding and unwinding is limited to be the same as the moving path of the transmission belt 250.

[0049] By setting a guiding member to limit the moving path of the magnetic sheet 220, the magnetic sheet 220 can be unfolded along a fixed moving path, that is, the unfolded state of the magnetic sheet 220 is guaranteed to be fixed, thereby preventing the magnetic sheet 220 from tilting at a large angle after unfolding and affecting the relative position relationship with the food placement area, thereby avoiding affecting the magnetic field effect.

[0050] By setting the support rod 240 and the transmission belt 250, the transmission belt 250 is sleeved on the support rod 240 and the shaft 210, and the magnetic sheet 220 is fixedly connected to the transmission belt 250, so that the moving path of the magnetic sheet 220 is limited to be consistent with the moving path of the transmission belt 250, thereby limiting the moving path of the magnetic sheet 220, avoiding the magnetic sheet 220 from tilting at a large angle after unfolding and affecting the relative position relationship with the food placement area, thereby avoiding affecting the magnetic field effect. At the same time, the magnetic sheet 220 is fixedly connected to the transmission belt 250, so that after the magnetic sheet 220 is in an unfolded state, it can be fixed in this state by the transmission belt 250, avoiding the magnetic sheet 220 from moving.

[0051] Furthermore, by respectively arranging two transmission belts 250 at the two ends of the shaft 210 , the magnetic sheet 220 is fixedly connected to the two transmission belts 250 , so that both sides of the magnetic sheet 220 can be subjected to force, thereby improving the stability of the magnetic sheet 220 during the activity.

[0052] Furthermore, by providing a connecting rod 260 and connecting the connecting rod 260 to the side of the magnetic sheet 220, the entire side of the magnetic sheet 220 can be subjected to force, thereby further improving the stability of the magnetic sheet 220 during movement.

[0053] It should be noted that, in some other embodiments, the guiding member may also be a clamping groove provided on the mounting frame, and the magnetic sheet moves in the clamping groove, and the moving path of the magnetic sheet is limited by the clamping groove.

[0054] like Figures 2 to 4 As shown, further, the magnetic field assembly 200 includes a driving device 270, and the driving device 270 is used to drive the magnetic sheet 220 to be rolled up or unfolded. Specifically, the driving device 270 is connected to the shaft 210 to drive the shaft 210 to rotate, thereby driving the magnetic sheet 220 to be rolled up or unfolded. The driving device 270 can be a motor, and the motor shaft of the motor is connected to the shaft 210, thereby driving the shaft 210 to rotate, thereby causing the magnetic sheet 220 to be unfolded or rolled up.

[0055] By providing the driving device 270 and utilizing the driving device 270 to drive the magnetic sheet 220 to be rolled up or unfolded, the use of the magnetic field assembly 200 is made more convenient.

[0056] It should be noted that in some other embodiments, the driving device can be connected to the magnetic sheet to drive the magnetic sheet to retract or unfold. For example, an electric retracting rod. In addition, the driving device can be a pneumatic, electric, hydraulic or other powered device.

[0057] like Figure 5 and Figure 6As shown, further, the refrigerator also includes a drawer 300, which is arranged in the storage compartment 101, and the internal space of the drawer 300 constitutes a food placement area. Specifically, the drawer 300 is arranged in the storage compartment 101 in a pull-out manner. The magnetic field assembly 200 is arranged at the rear side of the drawer 300. According to the different expansion degrees of the magnetic sheet 220, the coverage degree of the magnetic sheet 220 on the internal space of the drawer 300 in the front and rear directions of the refrigerator will also be different, so that the magnetic field generated by the magnetic sheet 220 in the internal space of the drawer 300 The range of action will also be different.

[0058] Combination Figures 1 to 6 As shown, if the magnetic sheet 220 is in a fully unfolded state, the magnetic sheet 220 completely covers the inner space of the drawer 300 from the rear side of the drawer 300. By continuously rolling up the magnetic sheet 220 from the fully unfolded state, the space of the drawer 300 covered by the magnetic sheet 220 can be reduced, thereby reducing the range of action of the magnetic field generated by the magnetic sheet 220 in the inner space of the drawer 300.

[0059] Combination Figures 1 to 7 As shown, the refrigerator also includes a partition plate 400, which is arranged in the food placement area in the storage compartment 101 (that is, the internal space of the drawer 300) to divide the food placement area into two areas arranged along the expansion direction of the magnetic sheet 220, and the partition plate 400 is slidably arranged along the expansion direction of the magnetic sheet 220.

[0060] Combination Figure 7 As shown, further, the partition plate 400 is provided with a slide column 410 , and the refrigerator is provided with a slide groove 102 extending along the unfolding direction of the magnetic sheet 220 .

[0061] Reference Figures 1 to 7 As shown, the magnetic sheet 220 is unfolded along the left-right direction of the refrigerator, and the partition plate 400 is arranged in the inner space of the drawer 300, so as to divide the inner space of the drawer 300 into two areas distributed on the left and right. Specifically, the front and rear side walls of the drawer 300 are provided with a slide groove 102, and the front and rear ends of the partition plate 400 are provided with a slide column 410, which is embedded in the slide groove 102 to support the partition plate 400, so that the partition plate 400 divides the food placement area into two left and right areas. At the same time, the partition plate 400 can slide along the left-right direction of the drawer 300 and slide to different positions, thereby changing the size of the two side areas.

[0062] By setting the partition plate 400 in the food placement area, the partition plate 400 can separate the food placement area into two areas arranged along the unfolding direction of the magnetic sheet 220, and the partition plate 400 can change the size of the two areas by sliding. Therefore, according to the different degrees of unfolding of the magnetic sheet 220, the partition plate 400 can be slid so that one area separated by the partition plate 400 corresponds to the coverage range of the magnetic sheet 220, so as to visually divide the magnetic field action area and the non-magnetic field action area, thereby improving the user experience.

[0063] Preferably, the partition plate 400 is made of magnetic isolation material.

[0064] It should be noted that in some other embodiments, drawers may not be provided, and shelves provided in the storage compartment may be used to form a food placement area. In this case, the partition plate may be slidably connected to the shelf or directly slidably connected to the box body.

[0065] It should be noted that, in some other embodiments, the refrigerator may be provided with two of the above-mentioned magnetic field components, and the two magnetic field components are arranged opposite to each other.

[0066] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
