Description

Technical Field

[0001] The utility model relates to the technical field related to washing devices, and in particular to a washing machine base and a washing machine. Background Art

[0002] As the number of washing machine loading functions increases, the weight of the washing machine also increases. In order to ensure the stability of the washing machine during operation, the chassis of the washing machine is usually very low. This makes it difficult to carry and move the washing machine. At the same time, it is not easy to install and move the washing machine in a narrow space, and it is not convenient for after-sales personnel to repair the washing machine.

[0003] The mobile washing bases currently available on the market all have a relatively high base height, requiring users to lift and carry them for installation, which is difficult to install or increases the cost of additional tools for installation, making it difficult for users to carry and move them independently. After installation, the height of the original washing machine is raised, or the original design support feet of the washing machine are replaced. Such lifting and modification can easily cause the washing machine to work unstably, resulting in greater noise or danger.

[0004] As can be seen from the above, the washing machine in the prior art has the problem of being inconvenient to move and transport. Utility Model Content

[0021] According to another aspect of the present invention, there is provided a washing machine, which includes the above-mentioned washing machine base and a body, and the body is disposed on the washing machine base.

[0022] Applying the technical solution of the present invention, the washing machine base includes a bottom plate, a bracket assembly and a roller assembly.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0032] 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.

[0033] 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.

[0034] In order to solve the problem that the washing machine in the prior art is inconvenient to move and carry, the utility model provides a washing machine, which includes a body and a washing machine base, and the body is arranged on the washing machine base. The body is the main structure of the washing machine for washing clothes, and the washing machine base is used to support the body, and the washing machine base is in contact with the ground.

[0035] Specifically, the type of washing machine may be a pulsator washing machine, a drum washing machine, or the like.

[0036] In this embodiment, the washing machine base in this application supports the body of the washing machine. When the washing machine needs to be moved, it is moved through the roller assembly on the washing machine base, which is beneficial to improving the movement efficiency. When the washing machine needs to be fixed, the use of the roller assembly is cancelled to achieve the bottom plate abutting against the ground, which is beneficial to improving the stability of the placement of the washing machine.

[0037] like Figures 1 to 3 As shown, the washing machine base includes a bottom plate 10, a bracket assembly 20 and a roller assembly 30, the bracket assembly 20 includes a first frame 210 and a second frame 220 extending along a first direction, the first frame 210 is arranged on the bottom plate 10, the second frame 220 is slidably arranged inside the first frame 210 along the first direction, the first frame 210 has a first track extending along a side away from the bottom plate 10, the second frame 220 has a second track obliquely arranged along a side away from the bottom plate 10 and extending along the first direction, at least a portion of the roller assembly 30 passes through and is slidably arranged inside the first track and the second track, as the second frame 220 slides, the second frame 220 provides a driving force for at least a portion of the roller assembly 30 to move relative to each other in the first track and the second track, and the roller assembly 30 moves toward or away from the side of the bottom plate 10.

[0038] Specifically, the washing machine base of the present application uses the first track on the first frame 210 and the second track on the second frame 220 to limit the roller assembly 30. When the second frame 220 slides on the first frame 210 in the first direction, the contact surface between the second track and the roller assembly 30 changes. Then, the second frame 220 drives the roller assembly 30 to move relative to the first track and the second track. The first frame 210 is fixedly connected to the bottom plate 10, and thus the roller assembly 30 moves along the first track towards or away from the bottom plate 10. Among them, when it is necessary to carry and move, slide the second frame 220 to make the roller assembly 30 move towards the side away from the bottom plate 10. The roller assembly 30 contacts the ground and supports the bottom plate 10, and thus the movement can be carried out through the roller assembly 30. Using the roller assembly 30 for movement improves the movement efficiency; when it is not necessary to carry, by sliding the second frame 220 in the reverse direction of the first direction, it can be realized that the contact roller assembly 30 abuts against and supports the ground, which is beneficial to improving the placement stability of the washing machine base.

[0039] Among them, both the first track and the second track are long hole structures, and at least a part of the roller assembly 30 moves relatively inside the long hole along the extension direction of the long hole. It can be understood that the relative movement means that the roller assembly 30 can move inside the second track while the second frame 220 slides and the contact position with the second track changes.

[0040] Since the second track in this embodiment extends towards the side away from the bottom plate 10 and is inclined in the first direction, when the second frame 220 slides in the first direction, the inner wall surface of the second track gives the roller assembly 30 a squeezing force towards or away from the bottom plate 10 and a squeezing force in the first direction; the first track extends in the direction away from the bottom plate 10, and at least a part of the roller assembly 30 can only move towards or away from the bottom plate 10 inside the first track. That is, the first track limits the roller assembly 30 in the first direction. Under the limiting action of the first track, when the roller assembly 30 receives the driving force brought by the sliding of the second track, it will move along the direction towards or away from the bottom plate 10. At this time, the positions of the roller assembly 30 inside the first track and the second track both change.

[0041] In this embodiment, one end of the second frame 220 is a pulling end, and the second frame 220 is pulled through the pulling end. It should be noted that being inclined in the first direction means that the distance between the side of the second track close to the pulling end and the bottom plate 10 is less than the distance between the side away from the pulling end and the bottom plate 10.

[0042] In this embodiment, a group of planes of the first track along the first direction abut against the roller assembly 30 to prevent the roller assembly 30 from being displaced along the first direction; specifically, two inner wall surfaces of the first track relatively arranged along the first direction abut against at least a portion of the roller assembly 30 and are slidably arranged to limit the roller assembly 30 along the first direction.

[0043] The two oppositely disposed long strips of the second track are respectively in contact with the roller assembly 30 , thereby facilitating the driving of the roller assembly 30 to move.

[0044] Specifically, the inner wall surface of the second track close to the base plate 10 abuts against at least a portion of the roller assembly 30, providing a driving force for the roller assembly 30 to move toward the side away from the base plate 10. The inner wall surface of the second track away from the base plate 10 abuts against at least a portion of the roller assembly 30, providing a driving force for the roller assembly 30 to move toward the side close to the base plate 10.

[0045] The inner wall surface of the second track has the function of squeezing the roller assembly 30 , and when at least a portion of the roller assembly 30 is squeezed and moved by the inner wall surface of the second track, it can be slidably arranged with at least a portion of the roller assembly 30 .

[0046] In this embodiment, two inner wall surfaces of the first track that are opposite to each other along the first direction abut against and slide against at least a portion of the roller assembly 30 to limit the roller assembly 30 along the first direction.

[0047] The washing machine base used in this embodiment adjusts the sliding position of the second frame 220 to achieve movement of the roller assembly 30 toward or away from the bottom plate 10. The overall structure is simple and easy to operate.

[0048] In this embodiment, a plurality of bracket assemblies 20 are provided, and the plurality of bracket assemblies 20 are arranged at intervals along a second direction perpendicular to the first direction.

[0049] like Figures 1 to 3 As shown, a channel structure is formed between the first track and the second track along a second direction perpendicular to the first direction, and at least a portion of the roller assembly 30 passes through the channel structure.

[0050] Among them, a part of the first track and a part of the second track form a channel structure along the second direction, and the channel structure is used for at least a part of the roller assembly 30 to pass through, so that one part of the roller assembly 30 is located inside the first track along the second direction, and the other part of the roller assembly 30 is located inside the second track.

[0051] Specifically, the first frame 210 has two first side plates spaced apart in the second direction. Each first side plate is provided with a first track. The second frame 220 is disposed in the area between the two first side plates. The second frame 220 has two second side plates spaced apart in the second direction. Each second side plate is provided with a second track. A channel structure is formed between the first tracks and the second tracks on the two first side plates and the two second side plates.

[0052] The two second tracks are disposed in the area between the two first tracks, and the first tracks and the second tracks are arranged in a one-to-one correspondence.

[0053] In this embodiment, the first direction is the X direction shown in the figure, and the second direction is the Y direction shown in the figure. X and Y are the length and width directions of the surface of the bottom plate 10.

[0054] As Figures 1 to 3 shown, the roller assembly 30 includes a connecting column and a universal wheel 310. The connecting shaft 330 penetrates through the first track and the second track. When the second frame 220 slides, the connecting shaft 330 moves relatively inside the first track and the second track to move toward or away from one side of the bottom plate 10. Universal wheels 310 are provided at both ends of the connecting shaft 330, and the universal wheels 310 are disposed on both sides of the bracket assembly 20.

[0055] Specifically, the setting of the universal wheels 310 is beneficial for multi-directional movement when the washing machine needs to be carried, thereby improving the convenience and efficiency of movement. The connecting shaft 330 is connected to the universal wheels 310, realizing the synchronous movement of the connecting shaft 330 and the universal wheels 310, which is beneficial to improving the consistency of the movement of the roller assembly 30 and is beneficial to improving the movement efficiency.

[0056] Furthermore, the connecting shaft 330 is used to penetrate through the first track and the second track. Along the second direction, a part of the connecting shaft 330 is located inside the first track, and another part of the connecting shaft 330 is located inside the second track. The connecting shaft 330 is an integral body, so the connecting shaft 330 has the effect of synchronous movement.

[0057] Among them, the connecting shaft 330 extends along the second direction.

[0058] In this embodiment, the connecting shaft 330 is slidably disposed inside the first track and the second track, and the connecting shaft 330 is tangent to a set of opposite inner wall surfaces of the first track and the second track.

[0059] The universal wheels 310 are arranged in pairs. Both ends of the connecting shaft 330 along the second direction are connected to the universal wheels 310. During the sliding process of the second frame 220, the inner wall surface of the second track drives the connecting shaft 330 to move, and then the connecting shaft 330 drives the universal wheels 310 to move synchronously up and down. So that after the connecting shaft 330 and the universal wheels 310 move in the direction away from the bottom plate 10, the universal wheels 310 contact the ground and move through the universal wheels 310.

[0060] In this embodiment, the roller assembly 30 further includes a bearing 320. The universal wheel 310 is connected to the connecting shaft 330 through the bearing 320. The bearing 320 plays a role of connecting and fixing, and the connecting shaft 330 is rotatably connected to the universal wheel 310 through the bearing 320.

[0061] In this embodiment, according to the different structures for driving the movement of the second frame 220, the following implementation manners are provided.

[0062] As Figures 1 to 3 shown in the specific implementation manner, the washing machine base further includes a handle 50. The first end of the handle 50 has a rotating part 510 and a connecting part 520. The rotating part 510 is rotatably connected to the first frame 210 or the bottom plate 10. Along the first direction, the connecting part 520 is connected to one end of the second frame 220. The connecting part 520 is used to push and pull the second frame 220 to slide. The second end of the handle 50 has a holding part 530.

[0063] Specifically, the handle 50 is used to facilitate manual operation to slide the second frame 220. The rotating part 510 of the handle 50 forms a rotation center. During the use of the handle 50, it rotates around the rotating part 510 through the holding part 530, and then the position of the connecting part 520 can be driven to move. The connecting part 520 pulls the second frame 220 to move, realizing the sliding of the second frame 220 inside the first frame 210.

[0064] Furthermore, since both the first frame 210 and the second frame 220 are arranged along the first direction, the second frame 220 slides along the first direction under the limiting action of the first frame 210.

[0065] In this embodiment, there is a mating part on the first frame 210 or the bottom plate 10 that is rotatably connected to the rotating part 510. One of the rotating part 510 and the mating part is a convex column, and the other is a rotating hole. The convex column extends along the side facing or away from the bottom plate 10. Among them, the structure of using the convex column and the rotating hole for cooperation realizes a simple and convenient rotating structure. The position where the mating part is arranged can be on the first frame 210 or the bottom plate 10 other than the second frame 220.

[0066] In the actual process of rotating the handle 50, since the second frame 220 is pulled to move by rotation, in order to make the second frame 220 move in the first direction, in this embodiment, the connecting portion 520 is a long hole extending in a second direction perpendicular to the first direction. The second frame 220 has a connecting shaft 330 disposed inside the long hole. The connecting shaft 330 can slide and rotate inside the long hole, and the inner wall of the long hole abuts against the connecting shaft 330 to drive the connecting shaft 330 to move in the first direction.

[0067] Specifically, the connecting portion 520 has a long hole structure. During the rotation of the handle 50, the rotating shaft abuts against the long hole in the first direction, thereby driving the second frame 220 to move in the first direction. While the second frame 220 is moving, the connecting shaft 330 undergoes relative displacement along the first direction inside the long hole, so as to convert the rotation action of the handle 50 into the action of pulling the second frame 220 in the first direction.

[0068] In a specific embodiment not shown in the figure, one end of the second frame 220 in the first direction has a handle portion, and the handle portion is spaced apart from the first frame 210 and the bottom plate 10.

[0069] Specifically, the handle portion is used to perform a pulling action in the first direction, thereby realizing the movement of the second frame 220 along the first direction.

[0070] It should be noted that the handle portion needs to be spaced apart from the first frame 210 and the bottom plate 10 to avoid the problem that the first frame 210 and the bottom plate 10 interfere with the movement of the handle portion in the first direction.

[0071] As Figures 1 to 3 shown, the surface of the first frame 210 facing the bottom plate 10 has a convex structure 211 disposed on the side facing the bottom plate 10. The convex structure 211 abuts against the bottom plate 10. Along a second direction perpendicular to the first direction, the universal wheels 310 of the roller assembly 30 are disposed on both sides of the convex structure 211.

[0072] Specifically, the convex structure 211 is provided to raise the height of the first frame 210, thereby increasing the distance between the connecting shaft 330 and the bottom plate 10. When the washing machine does not need to be moved, the roller assembly 30 can move towards the bottom plate 10 until it does not abut against the ground for support. That is, by providing the convex structure 211, the universal wheels 310 of the roller assembly 30 can be stored in this area.

[0073] In this embodiment, the washing machine base further includes feet 40 which are arranged on the bottom plate 10. The roller assembly 30 has a support position and a retracted position. As the second frame 220 moves, the roller assembly 30 switches between the support position and the retracted position. When the roller assembly 30 is in the support position, the distance between the end of the roller assembly 30 facing away from the bottom plate 10 and the bottom plate 10 is greater than the distance between the end of the foot 40 facing away from the bottom plate 10 and the bottom plate 10. When the roller assembly 30 is in the retracted position, the distance between the end of the roller assembly 30 facing away from the bottom plate 10 and the bottom plate 10 is less than the distance between the end of the foot 40 facing away from the bottom plate 10 and the bottom plate 10.

[0074] It can be understood that when the washing machine needs to be moved, by sliding the second frame 220 in the first direction, the roller assembly 30 is driven to move towards the side away from the bottom plate 10 to be in the support position. The universal wheels 310 of the roller assembly 30 in the support position come into contact with the ground and move on the ground. When it is not necessary to move, by moving the second frame 220, the roller assembly 30 is switched to the retracted position, and the feet 40 are abutted and fixed to the ground.

[0075] In this embodiment, a plurality of feet 40 are provided. The plurality of feet 40 are arranged on the bottom plate 10 at intervals along the circumference of the bottom plate 10. By providing a plurality of feet 40, it is beneficial to improve the stability of the washing machine placement.

[0076] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0077] The washing machine base of the present application uses the first track on the first frame 210 and the second track on the second frame 220 to limit the roller assembly 30. When the second frame 220 slides on the first frame 210 in the first direction, the contact surface between the second track and the roller assembly 30 changes. Then, the second frame 220 drives the roller assembly 30 to move relative to the first track and the second track. The first frame 210 is fixedly connected to the bottom plate 10, thereby realizing the movement of the roller assembly 30 along the first track towards or away from the bottom plate 10.

[0078] When it is necessary to move the washing machine, sliding the second frame 220 enables the roller assembly 30 to move towards the side away from the bottom plate 10. The roller assembly 30 comes into contact with the ground and supports the bottom plate 10, and then the washing machine can be moved through the roller assembly 30. Using the roller assembly 30 for movement improves the movement efficiency. When it is not necessary to move, by sliding the second frame 220 in the reverse direction of the first direction, the contact between the roller assembly 30 and the ground can be achieved for abutment and support, which is beneficial to improving the stability of the washing machine base placement.

[0079] The washing machine base adopted in this application realizes the movement of the roller assembly 30 towards or away from the bottom plate 10 by adjusting the sliding position of the second frame 220. The overall structure is simple and convenient to operate.
