[0002] With the improvement of the living standards of the people in our country, the demand for refrigerators is also increasing. Whether it is an embedded refrigerator or a free-standing ordinary refrigerator, it is usually placed on the ground or other fixed bases. However, it is very difficult to ensure that the ground or the fixed base is horizontal, which easily causes the refrigerator to be skewed and unstable, and there will be relatively large noises or other states during use. Especially for an embedded refrigerator, while being horizontally placed, it also needs to be flush with the surrounding cabinets. Therefore, it is particularly important to adjust the horizontal state and height of the refrigerator by adjusting the heights of the four feet of the refrigerator.

[0003] In the prior art, adjustable feet are provided at the four feet of the refrigerator to adjust the height and the horizontal placement state of the refrigerator. However, during the adjustment process, the adjustable feet to be adjusted need to be tilted away from the ground, and after adjustment, the refrigerator is placed upright again. After multiple adjustments, the horizontal placement of the refrigerator can be achieved. It is time-consuming and laborious, and the adjustment efficiency is low. Summary of the Invention

[0022] The present invention will be described in detail below in conjunction with the embodiments shown in the drawings. Please refer to Figures 1 to 4 shown, which is a preferred embodiment of the present invention. It should be noted, however, that these embodiments are not limitations on the present invention. Any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art based on these embodiments shall fall within the protection scope of the present invention.

[0023] The words expressing positions and directions described within the present invention are all referenced during the use of the adjustable foot device. The installation side of the adjustable foot device close to the bottom of the refrigerator is the upper side, and the supporting side of the adjustable foot device on the bearing surface is the lower side. When the refrigeration device is in use, the side close to the user is the front, and the remaining directions "rear", "left", and "right" are all referenced with the front as the reference. It can be known that this is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation on the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0024] Furthermore, it should be noted that in the description of the present invention, unless otherwise clearly defined and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can also be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Please refer to Figures 1~4 As shown, the present invention provides an adjustable foot device 10 and a refrigeration device having the adjustable foot device 10. The adjustable foot device 10 is used to be fixed to the bottom of the box body in the refrigeration device, so as to place the refrigeration device on a bearing surface. Thus, by adjusting the height of the adjustable foot device 10, the four corners of the refrigeration device can be adjusted to be horizontal, thereby avoiding the inclination problem of the refrigeration device caused by the flatness of the bearing surface and achieving a horizontal placement, which is safe and reliable.

[0026] Of course, it can be understood that the adjustable foot device 10 is not limited to being applied to the refrigeration device, and can also be applied to other household appliances such as washing machines and dryers. The refrigeration device includes but is not limited to a refrigerator 20, a freezer, a cold cabinet, etc. Hereinafter, taking the refrigeration device as the refrigerator 20 as an example, specific elaboration will be carried out. Of course, it is not limited thereto.

[0027] Meanwhile, the above-mentioned "bearing surface" can be any feasible plane, inclined plane, arc surface, etc. For example, it can be the ground, a tabletop, a step surface, etc. Hereinafter, taking the bearing surface as the ground as an example, specific elaboration will be carried out.

[0028] Combined with Figures 2 - 4 As shown, the adjustable foot device 10 includes a base 1 for assembling to the bottom end surface of the box body of the refrigerator 20, and at least one set of adjustable foot structures 2 installed on the base 1. The adjustable foot structures 2 are used to support on the ground. After adjusting the position of the adjustable foot structures 2 in the vertical direction, the distance between the base 1 and the ground can be adjusted, that is, the distance between the refrigerator 20 and the ground can be adjusted. Thus, the level of the refrigerator 20 can be adjusted.

[0029] Furthermore, the base 1 has mounting parts corresponding one-to-one to the adjustable feet structure 2. Each mounting part is provided with two mounting plates 11 that are opposite and spaced apart in a horizontal first direction. An installation cavity that opens downward is formed between the two mounting plates 11, and the mounting plates 11 extend in the vertical direction. The adjustable feet structure 2 includes a feet assembly 21 that is movably connected in the vertical direction within the installation cavity, and an adjustment assembly 22 for driving the feet assembly 21 to move in the vertical direction. By operating the adjustment assembly 22, the user can drive the feet assembly 21 to move in the vertical direction, and can adjust the distance between the base 1 and the ground, that is, adjust the distance between the refrigerator 20 and the ground. Thus, the levelness of the refrigerator 20 can be adjusted.

[0030] The feet assembly 21 includes a movable frame 211 that is slidably connected in the vertical direction within the installation cavity, and a foot 212 located at the lower end of the movable frame 211. The movable frame 211 includes side walls 2111 corresponding one-to-one to the mounting plates 11. One of the mounting plate 11 and the corresponding side wall 2111 is provided with a first guide groove 111 that extends horizontally in a second direction, and the other is provided with a second guide groove 2112 that extends obliquely in the vertical direction in the second direction. The second direction is perpendicular to the first direction. The adjustment assembly 22 includes a guide rod 221 that is simultaneously inserted into the first guide groove 111 and the corresponding second guide groove 2112, and a driving mechanism 222 for driving the guide rod 221 to move in the second direction. It can be known that the guide rod 221 is always located at the intersection of the projections of the first guide groove 111 and the second guide groove 2112 on the vertical plane in the second direction. When the driving mechanism 222 drives the guide rod 221 to move in the second direction, the guide rod 221 moves along the first guide groove 111. Since the movable frame 211 and the mounting plate 11 can only move relative to each other in the vertical direction and cannot move horizontally relative to each other, thus, the guide rod 221 pushes the second guide groove 2112 to move relative to the guide rod 221, driving the movable frame 211 to move in the vertical direction, so as to drive the feet assembly 21 to move in the vertical direction.

[0031] Specifically, the second guiding groove 2112 includes a first end A and a second end B opposite to the first end A, and the first end A is lower than the second end B; the first guiding groove 111 includes a third end C corresponding to the first end A and a fourth end D corresponding to the second end B. In the embodiment where the first guiding groove 111 is provided on the mounting plate 11 and the second guiding groove 2112 is provided on the side wall 2111, when the guide rod 221 moves towards the third end C, the guide rod 221 simultaneously moves towards the first end A, driving the foot component 21 to move upward, reducing the distance between the base 1 and the ground, that is, reducing the distance between the refrigerator 20 and the ground; when the guide rod 221 moves towards the fourth end D, the guide rod 221 simultaneously moves towards the second end B, driving the foot component 21 to move downward, increasing the distance between the base 1 and the ground, that is, increasing the distance between the refrigerator 20 and the ground. In the embodiment where the first guiding groove 111 is provided on the side wall 2111 and the second guiding groove 2112 is provided on the mounting plate 11, when the guide rod 221 moves towards the third end C, the guide rod 221 simultaneously moves towards the first end A, driving the foot component 21 to move downward, increasing the distance between the base 1 and the ground, that is, increasing the distance between the refrigerator 20 and the ground; when the guide rod 221 moves towards the fourth end D, the guide rod 221 simultaneously moves towards the second end B, driving the foot component 21 to move upward, reducing the distance between the base 1 and the ground, that is, reducing the distance between the refrigerator 20 and the ground.

[0032] In a specific embodiment, the first guiding groove 111 is provided on the mounting plate 11 and the second guiding groove 2112 is provided on the side wall 2111. Thus, when adjusting the height of the foot component 21 through the adjusting component 22, only the foot component 21 moves in the vertical direction, and the adjusting component 22 does not move in the vertical direction, which is beneficial for the user to adjust. Of course, this is not the only limitation.

[0033] Further, in the embodiment where the first guiding groove 111 is provided on the mounting plate 11 and the second guiding groove 2112 is provided on the side wall 2111, the first end A and the third end C are on the same vertical line, and the horizontal distance between the second end B and the first end A is not less than the horizontal distance between the fourth end D and the third end C. Thus, when the guide rod 221 moves to the third end C, the guide rod 221 is simultaneously located at the first end A, which can maintain the relative stability between the guide rod 221 and the first guiding groove 111 and the second guiding groove 2112, avoid the foot component 21 from shaking up and down under the gravity of the refrigerator 20, and improve the stability of the adjustable foot device 10.

[0034] Furthermore, one of the side wall 2111 and the mounting plate 11 is provided with a slide groove 112 extending in the vertical direction, and the other is provided with a slide plate 2113 matched with the slide groove 112. When the foot assembly 21 moves in the vertical direction, the slide plate 2113 moves relative to the slide groove 112. By providing the matched slide groove 112 and the slide plate 2113, the horizontal movement of the foot assembly 21 can be limited, the stability of the vertical movement of the foot assembly 21 is improved, and the stability of the adjustable foot device 10 is improved.

[0035] In a specific embodiment, the slide 2113 is disposed at both ends of the side wall 2111 in the second direction, and the slide 2113 protrudes from the end of the side wall 2111 along the first direction toward the mounting plate 11 corresponding to the side wall 2111. Of course, this is not limited thereto.

[0036] Specifically, combined Figure 3 As shown, the mounting portion further includes a connecting plate 12 connecting the ends of the two mounting plates 11 in the second direction, and the two connecting plates 12 are spaced apart along the second direction. The connecting plate 12 and the mounting plate 11 are jointly arranged to form the slide groove 112 .

[0037] Furthermore, the thickness of the mounting plate 11 is greater than the thickness of the connecting plate 12 , which can further improve the stability of the adjustable foot device 10 .

[0038] Specifically, the connection plate 12 on the side corresponding to the driving mechanism 222 is provided with a clearance groove 121 for the driving mechanism 222 to pass through.

[0039] In a specific embodiment, the driving mechanism 222 includes a screw rod 2221 connected to the guide rod 221 and a driving screw sleeve 2222 threadedly connected to one end of the screw rod 2221 away from the guide rod 221. When the driving screw sleeve 2222 is operated to rotate, the screw rod 2221 is driven to move along the second direction, thereby driving the guide rod 221 to move along the second direction.

[0040] Furthermore, one end of the screw rod 2221 away from the driving screw sleeve 2222 is connected to a fixing block 2223, and the fixing block 2223 is penetrated by a through hole 2224 extending along the first direction, and the guide rod 221 is inserted into the through hole 2224, so as to facilitate the assembly of the adjustable foot device 10.

[0041] Further, the driving screw sleeve 2222 has an operating portion at one end away from the guide rod 221. Specifically, the operating portion can be configured as a non-circular nut or a non-circular groove, such as a hexagonal nut or a hexagonal groove, for user operation.

[0042] In a specific embodiment, after the adjustable feet device 10 is installed on the bottom end face of the refrigerator 20, the first direction is the left - right direction, the second direction is the front - back direction, and the driving mechanism 222 is connected to the front side of the guide rod 221. Thus, the user can operate the driving from the front side, which is convenient for the user to operate. Of course, this is not the only limitation.

[0043] Specifically, the base 1 includes a base plate 13 for assembling to the bottom end face of the cabinet of the refrigerator 20, and a peripheral wall extending downward from the periphery of the base plate 13. The peripheral wall includes a front wall 14 and a rear wall 15 which are oppositely arranged, and a left wall and a right wall which are oppositely arranged. An operation hole 141 is formed through the front wall 14, and the operation part in the driving mechanism 222 is exposed outward from the operation hole 141 for the convenience of user operation.

[0044] Furthermore, at the positions corresponding to the mounting plate 11 on the left wall and the right wall, there are notches 16. On the one hand, it is beneficial to the assembly of the adjustable feet structure 2. On the other hand, it can also prevent the guide rod 221 from protruding from the outer surface of the base 1 after the adjustable feet structure 2 is assembled to the base 1, which affects the embedding of the refrigerator 20 and also has a certain risk, and affects the overall appearance effect of the refrigerator 20.

[0045] In a specific embodiment, the feet 212 are rollers rotatably connected to the lower end of the movable frame 211. Thus, after the adjustable feet device 10 is installed on the bottom end face of the refrigerator 20, the rollers are supported on the ground, and the position of the refrigerator 20 can be adjusted by pushing the refrigerator 20 to make the rollers rotate, which is convenient for adjusting the position of the refrigerator 20.

[0046] Specifically, the feet assembly 21 further includes a rotating shaft 213 for rotatably connecting the roller to the movable frame 211 and a locking screw 214 for restricting the axial movement of the rotating shaft 213. After the roller is rotatably connected to the movable frame 211 through the rotating shaft 213, the locking screws 214 are fixed at both opposite ends of the rotating shaft 213, and the roller can be stably rotatably connected to the movable frame 211.

[0047] Furthermore, in a specific embodiment, the base 1 has two mounting parts, and the adjustable feet device 10 includes two groups of adjustable feet structures 2 corresponding to the two mounting parts respectively, which can adjust the heights of multiple positions of the refrigerator 20 and improve the integration degree of the adjustable feet device 10.

[0048] Specifically, the two mounting parts are spaced and staggered along the second direction, and the two mounting parts are spaced and staggered in the front-to-back direction. Specifically, one of the two mounting parts is arranged forward, the other is arranged backward, one is arranged leftward, and the other is arranged rightward. This can avoid interference between the two driving mechanisms 222 when they are exposed outward from the same side.

[0049] Specifically, the base 1 is in a rectangular parallelepiped shape. When the base 1 is mounted on the bottom end surface of the refrigerator 20, the length direction of the base 1 extends along the front-back direction, and the width direction of the base 1 extends along the left-right direction. That is, the first direction is the width direction of the base 1, and the second direction is the length direction of the base 1.

[0050] Furthermore, the driving mechanisms 222 of the two adjustable foot structures 2 are exposed outward from the same side of the base 1. Specifically, when the base 1 is mounted on the bottom end surface of the refrigerator 20, the driving mechanisms 222 of the two adjustable foot structures 2 are exposed outward from the front side of the base 1. Thus, the heights of the two adjustable foot structures 2 can be adjusted from the front side of the refrigerator 20, that is, the levels of the front and rear ends of the adjustable foot device 10 can be adjusted, and the adjustment is convenient.

[0051] Combination Figure 1 As shown, in this embodiment, the adjustable foot device 10 is provided on both the left and right sides of the body of the refrigerator 20, and each of the adjustable foot devices 10 has the adjustable foot structure 2 located on the front and rear sides, so that the height of the four corners of the bottom of the refrigerator 20 can be adjusted from the front side of the refrigerator 20, and the adjustment is convenient.

[0052] Compared with the prior art, the adjustable foot device 10 in the present invention can drive the foot assembly 21 to move in the vertical direction by setting a guide rod 221 to cooperate synchronously with the first guide groove 111 and the second guide groove 2112 with two different extension directions, so as to adjust the distance between the base 1 and the ground, that is, adjust the distance between the refrigerator 20 and the ground, and adjust the level of the refrigerator 20 without lifting one side of the refrigerator 20 for adjustment. The structure is simple and the adjustment is convenient.

[0053] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0054] The series of detailed descriptions listed above are only specific descriptions of the feasible implementation manners of the present invention, and they are not intended to limit the protection scope of the present invention. Any equivalent implementation manners or modifications made without departing from the technical spirit of the present invention should be included within the protection scope of the present invention.
