[0002] To facilitate the movement of household appliances, a moving mechanism is usually installed at the bottom of the household appliances. The moving mechanism has a liftable roller assembly. When it is necessary to move the household appliances, the roller assembly of the moving mechanism is lowered to improve the moving convenience; when the household appliances do not need to be moved, the roller assembly is raised and retracted.

[0003] In the current pursuit of efficient space utilization, many household appliances are designed to be embedded in cabinets or other structures to save space. However, the existing moving mechanisms usually adopt a unified specification, and this unified specification design has certain limitations in the scenario of embedded installation. The embedding depth of many household appliances is small. When the household appliances are pushed into the cabinet, the too-long structure of the moving mechanism may interfere with the cabinet. Once the interference occurs, it will not only hinder the smooth embedding of the household appliances into the cabinet, but also is very likely to cause serious damage to the cabinet and the household appliances themselves during the forced embedding process, thereby affecting the normal use of the products and greatly reducing the user experience.

Detailed implementation manners

[0046] The preferred implementation manners of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present application and are not intended to limit the protection scope of the present application. Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios.

[0047] It should be noted that in the description of the present application, the terms "upper", "lower", "top", and "bottom" refer to the upper and lower parts, top and bottom of the household appliance based on the height direction in the use state. "Front" refers to the direction close to the door based on the horizontal direction in the use state of the household appliance, and "rear" refers to the direction close to its back panel based on the horizontal direction in the use state of the household appliance. The width direction is the direction from one side panel to the other side panel of the household appliance. In addition, it should be noted that in the description of the present application, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0048] To solve the problem that the existing household appliances are prone to interference during the embedding process when a moving mechanism is installed at the bottom. As Figures 1 to 4As shown in the figure, the present application provides a moving mechanism for household appliances, including a base 100 and a roller assembly 200. The base 100 is set to be adjustable in length, and the roller assembly 200 is vertically movably arranged at the bottom of the base 100. The moving mechanism is configured such that when the roller assembly 200 is in the lowered state, the roller assembly 200 can support the household appliance, and when the roller assembly 200 is in the raised state, the feet assembly at the bottom of the household appliance can support the household appliance.

[0049] When the roller assembly 200 of the moving mechanism descends, the rollers 210 in the roller assembly 200 bear the load to achieve flexible displacement of the household appliance; when the roller assembly 200 rises and resets, the feet assembly of the household appliance realizes stable support. Among them, since the base 100 is set to be adjustable in length, it can be adaptively adjusted according to the size of the household appliance. For small household appliances, the length of the base 100 is shortened to avoid interference caused by exposure, and for large household appliances, the length of the base 100 is extended to improve the installation stability. This not only ensures the compatibility with various models of household appliances but also realizes seamless switching between the moving and fixed states of the household appliance, significantly improving the installation adaptability, use stability, and operation convenience of the household appliance product. It can be understood that the feet assembly of the household appliance can be a combination of multiple individual feet.

[0050] The following specifically introduces the household appliance of the present application and the moving mechanism at the bottom of the household appliance.

[0051] The household appliance of the present application can be a clothes treatment device such as a washing machine, a washer-dryer, a dryer or a shoe washing machine, or can be a refrigerator, etc. The present application does not limit the specific form of the household appliance. Specifically, the moving mechanism of the present application includes a base 100, a moving plate 510, a pushing structure 400 and a roller assembly 200. The base 100 includes a base body 110, a first mounting plate 120 and a third mounting plate 140. The first mounting plate 120 is provided at one end in the length direction of the base body 110, and the third mounting plate 140 is provided at the other end in the length direction of the base body 110. The base body 110 is provided with a guiding groove (the guiding direction of the guiding groove is consistent with the length direction of the base body 110). The roller assembly 200 includes a roller 210 and a connecting arm 220. One end of the connecting arm 220 is rotatably connected to the side wall of the guiding groove, and the other end of the connecting arm 220 is rotatably connected to the roller 210. The moving plate 510 is movably arranged in the guiding groove. The moving plate 510 includes a pushing section 512. First vertical plates 520 and second vertical plates 530 are provided on both sides of the pushing section 512 in the width direction, so that the pushing section 512, the first vertical plates 520 and the second vertical plates 530 enclose to form a moving groove. Among them, the moving groove fits with each surface of the guiding groove, that is, the pushing section 512 fits with the bottom of the guiding groove, and the first vertical plates 520 and the second vertical plates 530 respectively fit with the two side walls of the guiding groove, so as to realize the stable movement of the moving plate 510 and avoid shaking. The pushing structure 400 of the present application is arranged on the pushing section 512. The pushing structure 400 is used to push the roller assembly 200 to descend and abut against the roller assembly 200 when the roller assembly 200 descends, so as to realize the roller assembly 200 supporting the household appliance and facilitate the movement of the household appliance by the rotation of the roller 210.

[0052] In the above introduction, the first mounting plate 120 and the base body 110 are preferably integrally formed. In addition, it can be understood that the guiding groove should include a plate body and third vertical plates and fourth vertical plates provided on both sides in the width direction of the plate body. The third vertical plates, the fourth vertical plates and the plate body enclose to form the above-mentioned guiding groove. The guiding groove is preferably a U-shaped groove, but can also be replaced by a guiding groove with one end blocked and the other end open in the length direction, etc. These possible form adjustments do not deviate from the principle of the present application and are all within the protection scope of the present application.

[0053] Possibly, the roller assembly 200 further includes a third shaft 230 and a fourth shaft 240. The rollers 210 are rotatably connected to opposite ends of the third shaft 230. The number of connecting arms 220 is two. A first shaft hole is provided at one end of each of the two connecting arms 220. The portion of the third shaft 230 between the two rollers 210 at both ends is fixed in the first shaft holes of the two connecting arms 220. The two connecting arms 220 are spaced apart from each other along the third shaft 230. A second shaft hole is provided at the end of each of the two connecting arms 220 away from the first shaft hole. The fourth shaft 240 is rotatably connected in each second shaft hole. Wherein, second strip-shaped holes are provided on both the first vertical plate 520 and the second vertical plate 530 of the moving groove along the moving direction. Both ends of the fourth shaft 240 pass through the second strip-shaped holes on both sides and are fixedly connected to the side wall of the guiding groove to ensure the smooth movement of the moving plate 510.

[0054] It should be noted that the above introduction is only exemplary. As long as it is ensured that the roller assembly 200 can be lifted and lowered, its specific setting method can be adjusted. For example, the number of rollers 210 can be set to 1 or more than 2. "The rollers 210 are rotatably connected to opposite ends of the third shaft 230" can be replaced with "The rollers 210 are rotatably connected to the middle of the third shaft 230". In this case, the first shaft holes of the two connecting arms 220 can be fixed to both ends of the third shaft 230, and the rollers 210 can be located in the guiding groove. Another example is that the rollers 210 can be fixedly connected to the third shaft 230, and the third shaft 230 is rotatably connected in the first shaft hole. Another example is that the fourth shaft 240 is rotatably fixed in the second shaft hole, and the fourth shaft 240 is rotatably connected to the side portion of the guiding groove. Another example is that the number of connecting arms 220 can be set to 1 or more than 2.

[0055] Refer to Figure 3 , the bottom of the household appliance of the present application has a protruding extension edge 900. The extension edge 900 can be located on the side close to the door body of the household appliance, that is, the front side of the household appliance. The extension edge 900 is arranged along the width direction of the household appliance. The extension edge 900 can be an extension edge 900 extending downward from the bottom side of the front panel of the household appliance, etc. The extension edge 900 is fixedly connected to the bottom plate of the household appliance. For example, the bottom plate has a flanging, and after the flanging is attached to the extension edge 900, it is fixedly connected by means such as bolt connection and welding, so as to enhance the structural strength of the household appliance and improve the overall stability. The extension edge 900 can also provide protection for the components at the bottom of the household appliance to effectively prevent damage or scratching of the bottom structure of the household appliance by external objects, and can also be used as a decorative panel, etc.

[0056] Possibly, the moving mechanism of the present application further includes a handle structure 600. The third mounting plate 140 has a groove 142 on the top surface, which is arranged along the width direction of the base body 110. The groove 142 extends towards the bottom surface of the third mounting plate 140 to form a protruding portion 143 on the bottom surface of the third mounting plate 140. The two ends of the groove 142 in the width direction of the household appliance penetrate through, and are used to accommodate the extension edge 900 introduced above, so as to ensure that the base 100 is horizontally installed at the bottom of the household appliance and avoid the movement of the moving mechanism being blocked due to inclination or instability. In addition, the moving plate 510 of the present application further has a bending section 511 on one side close to the third mounting plate 140 in the length direction. The bending section includes a first extension section 5111 and a second extension section 5112. The first extension section 5111 bends away from the base 100 from the pushing section 512, and the second extension section 5112 bends towards the protruding portion 143 from the first extension section 5111 and crosses the protruding portion 143. The handle structure 600 is connected to the part of the second extension section 5112 that crosses the protruding portion 143, so as to facilitate the user to hold the handle part 610 from the front of the household appliance, thereby driving the moving plate 510 to reciprocate.

[0057] The handle structure 600 of the present application has a handle part 610, a first connecting part 620 and a second connecting part 630 arranged on the handle part 610. The first connecting part 620 is rotatably connected to the third mounting plate 140 through a first shaft. A second shaft is provided on the second connecting part 630, and a guiding hole (which can be a long hole) is provided on the second extension section 5112. The second shaft is movably arranged in the guiding hole. Among them, a limiting block can be provided at the end of the second shaft to prevent the second shaft from disengaging from the guiding hole. Possibly, the handle part 610, the first connecting part 620 and the second connecting part 630 can be integrally formed and made of metal material. A plastic sleeve is sleeved at the end of the handle part 610, and a wave structure is formed on the plastic sleeve to facilitate the user to hold the handle part 610.

[0058] The working principle of the moving mechanism of the present application will be introduced below. When it is necessary to lower the roller 210 to move the household appliance, the handle part 610 is rotated by a certain angle, so that the moving groove moves smoothly along the first direction (such as moving forward) under the guidance of the guiding groove. The pushing structure 400 on the pushing section 512 starts to push the roller assembly 200, so that the connecting arm 220 of the roller assembly 200 rotates away from the base body 110, and the roller 210 descends to contact the ground. The pushing structure 400 abuts against the roller assembly 200, and the roller assembly 200 supports the household appliance, so that the household appliance can be moved by the roller 210 in the roller assembly 200. When it is necessary to raise and retract the roller assembly 200, the handle part 610 is rotated by a certain angle in the reverse direction, and the moving groove moves smoothly along the second direction opposite to the first direction (such as moving backward) under the guidance of the guiding groove. The pushing structure 400 moves away from the roller assembly 200, so that the roller assembly 200 can be raised and retracted. At this time, the foot assembly of the household appliance contacts the ground.

[0059] Among them, the present application does not limit the specific form of the pushing structure 400. Two possible implementation manners will be introduced below as examples.

[0060] In the first possible implementation manner, the pushing structure 400 is a wedge-shaped block, which has an inclined surface. The inclined surface is arranged facing the roller assembly 200. One end of the inclined surface is connected to the moving plate 510, so that when the moving plate 510 moves along the first direction, the inclined surface can extend into the gap between the roller assembly 200 and the moving plate 510, thereby guiding the roller assembly 200 to rotate away from the moving plate 510. When the moving plate 510 moves in the reverse direction, the wedge-shaped block moves away from the roller assembly 200, so that the roller assembly 200 can be retracted.

[0061] In the second possible implementation manner, the pushing structure 400 is arranged as inclined grooves provided on the first vertical plate 520 and the second vertical plate 530. Both opposite side walls of the guiding groove have notches arranged vertically. Both ends of the third shaft 230 are respectively arranged in the inclined grooves on both sides and are respectively arranged in the notches on both sides of the guiding groove. In this case, the roller 210 can be located outside the guiding groove, and the connecting arm 220 can be located in the moving groove. In this setting manner, when the moving plate 510 moves along the first direction, the roller assembly 200 gradually descends and unfolds under the drive of the inclined wall of the inclined groove until the roller 210 contacts the ground. When the moving plate 510 moves in the reverse direction, the inclined wall of the inclined groove moves away from the roller assembly 200, so that the roller assembly 200 can be retracted. Among them, the purpose of setting the notches is not only for avoidance, but also to provide a precise moving path for the third shaft 230, effectively avoiding the deviation and misalignment caused by rotational looseness, thereby ensuring the smoothness and stability of the unfolding and retracting actions of the roller assembly 200.

[0062] It can be understood that a notch is provided on the side wall of the guiding groove and arranged vertically, that is, the notch penetrates from one side of the guiding groove close to its groove bottom to the other side of the guiding groove far from the groove bottom. In other words, after the moving mechanism is installed at the bottom of the household appliance and the household appliance is in a normal placement state, the notch groove is arranged vertically.

[0063] The moving mechanism of the present application further includes an adjusting member 130. The adjusting member 130 includes an adjusting body 131 and a second mounting plate 132 provided on the adjusting body 131. The adjusting body 131 is movably arranged on the base body 110 along the length direction of the base body 110, so that the second mounting plate 132 can expand and contract relative to the first mounting plate 120; when the second mounting plate 132 retracts, at least one of the first mounting plate 120 and the second mounting plate 132 is for installing the first foot 810 in the foot assembly, and when the second mounting plate 132 extends, the second mounting plate 132 is for installing the first foot 810.

[0064] Specifically, the second mounting plate 132 is stacked on the first mounting plate 120. The first mounting plate 120 has a first mounting hole 121, and the second mounting plate 132 has a second mounting hole 1321. Possibly, both the first mounting hole 121 and the second mounting hole 1321 are strip-shaped holes arranged along the length direction of the base body 110. When the second mounting plate 132 retracts, there is an overlapping part between the first mounting hole 121 and the second mounting hole 1321, and the overlapping part is used for the first foot 810 to pass through. When the second mounting plate 132 extends, the part of the second mounting hole 1321 independent of the first mounting hole 121 is used for the first foot 810 to pass through.

[0065] When the moving mechanism is applied to household appliances with a small depth, the adjusting body 131 can be moved inward toward the inside of the base body 110, so that the second mounting plate 132 retracts to the initial position. This initial position may not protrude from the first mounting plate 120 or may protrude from the first mounting plate 120. This application does not limit it. At this time, the strip-shaped holes of the first mounting hole 121 and the second mounting hole 1321 have an overlapping part, forming an overlapping mounting area. The user can flexibly select the best mounting point within the length range of the overlapping mounting area according to the chassis structure of the household appliance, so that the first foot 810 passes through the overlapping part and is fixed to the bottom of the household appliance. At the same time, the superimposed structure formed by the double-layer mounting plates significantly improves the bearing stability. For household appliances with a large depth, by moving the adjusting body 131 outward and extending it, the second mounting plate 132 is fully unfolded. At this time, the independent area of the second mounting hole 1321 is exposed, which not only provides an extended support surface matching the size of large household appliances, but also ensures the precise positioning and installation of the first foot 810 within a larger span through the strip-shaped hole. In short, the above setting method is not only applicable to the embedded installation of household appliances of different specifications, but also can provide stable support for household appliances through the reasonable installation position of the first foot 810. And by integrating the moving mechanism into the first foot 810 of the household appliance, no additional structural installation is required, thus improving the space utilization rate, simplifying the manufacturing process and improving the installation convenience.

[0066] As a possible implementation manner, the second mounting plate 132 is stacked on the bottom of the first mounting plate 120. The moving mechanism further includes a gasket 300. The gasket 300 is used to be disposed on the top of the second mounting plate 132 outside the first mounting plate 120 when the second mounting plate 132 extends. The gasket 300 has a fourth mounting hole 310 for the first foot 810 to pass through. Since the second mounting plate 132 is stacked on the bottom of the first mounting plate 120, it avoids the second mounting plate 132 from forming a protruding part on the top of the base body 110, thus ensuring the horizontal installation of the moving mechanism. At the same time, since the gasket 300 is used to be disposed on the top of the second mounting plate 132 outside the first mounting plate 120 when the second mounting plate 132 extends, the gasket 300 can fill the gap between the second mounting plate 132 and the bottom of the household appliance, reducing or avoiding the vibration noise of the second mounting plate 132. Further, since the gasket 300 has a fourth mounting hole 310 for the first foot 810 to pass through, when the second mounting plate 132 extends, the formed double-layer superimposed structure significantly improves the bearing stability. Among them, one side or both sides of the gasket 300 in the thickness direction are provided with shock-absorbing felts to avoid resonance noise with the casing of the household appliance.

[0067] As a possible implementation, both side walls of the guide groove have first strip holes 111 arranged along the length direction of the guide groove, the adjustment body 131 is arranged at the bottom of the base body 110, the adjustment body 131 has a slide groove 1311, the guide groove is located in the slide groove 1311, the two side walls of the slide groove 1311 are connected with connecting shafts 133, and the connecting shafts 133 are arranged in the first strip holes 111 on the two side walls of the guide groove. Further, the adjustment body 131 also has a connecting plate 1312, the connecting plate 1312 is attached to the side wall of the guide groove, and one end of the connecting plate 1312 is connected to the side wall of the slide groove 1311, and the other end is connected to the second mounting plate 132 to avoid affecting the lifting and lowering of the roller assembly 200. The connecting plate 1312 and the side wall of the slide groove 1311 can be located on the same plane, and can be arranged vertically or at an angle with the second mounting plate 132. The adjusting body 131, the connecting plate 1312 and the slide groove 1311 are preferably formed in one piece. Furthermore, the first vertical plate 520 and the second vertical plate 530 are both provided with a third strip hole arranged along the length direction of the guide groove, the third strip hole overlaps with the first strip hole 111, and the connecting shaft 133 is also located in the first strip hole 111 and the third strip hole.

[0068] The adjusting body 131 is arranged at the bottom of the base body 110, so that the adjusting body 131 does not constitute a protruding part on the top of the base body 110, thereby ensuring the horizontal installation of the moving mechanism. In addition, a double-layer guide system is formed by the nesting of the slide groove 1311 and the guide groove. The sliding track of the connecting shaft 133 in the first strip hole 111 strictly limits the moving direction of the adjusting body 131, ensuring that the base 100 always moves in a straight line during the length adjustment process to avoid deviation or twisting. The symmetrical tracks formed by the first strip holes 111 on both sides make the adjusting body 131 evenly stressed when extending and retracting, effectively preventing the structure from getting stuck.

[0069] As a possible implementation, the base 100 further includes a third mounting plate 140, which is disposed at the other end of the base body 110 in the length direction. The third mounting plate 140 is preferably formed integrally with the base body 110, and the third mounting plate 140 has a third mounting hole 1411, which is used to install the second foot 820 in the foot assembly. The first foot 810 can be the original rear foot of the household appliance, and the second foot 820 can be the original front foot of the household appliance, so that the mobile mechanism is fixed by the original foot of the household appliance. In other words, the mobile mechanism of the present application can not only be fixed by the original foot of the household appliance, but also can be applied to household appliances of different models.

[0070] As a possible implementation, an annular rib 1412 is provided at the bottom of the third mounting hole 1411. The annular rib 1412 is flush with the second mounting plate 132, so as to ensure that the first foot 810 and the second foot 820 are mounted on the same horizontal plane, ensuring the fastening degree between the feet and the base 100 to effectively bear the weight of the household appliance and the vibration during use. Among them, the third mounting hole 1411 can be located between the protruding portion 143 and the guiding groove, so that the second foot 820 is located within the extending edge 900, so as to effectively protect the second foot 820 through the extending edge 900 and avoid damage to the second foot 820 at the front due to collision.

[0071] As a possible implementation, the third mounting plate 140 has a first part 141. The third mounting hole 1411 is provided in the first part 141. The first part 141 and the first mounting plate 120 are located on the same side in the width direction of the base body 110. Thus, it can not only avoid interfering with the movement of the moving plate 510, but also ensure that when the moving mechanisms are installed on both sides in the width direction of the bottom of the household appliance, the width between the first feet 810 on both sides is the same as the width between the second feet 820 on both sides, thereby improving the support stability.

[0072] As an alternative implementation, the number of the adjusting bodies is at least two. The adjusting bodies are telescopically arranged between each other. One side of the adjusting body is fixedly or slidably connected to the base body, and the other side of the adjusting body is connected to the second mounting plate (such as integrally formed). In this case, the setting of the connecting plate 1312 can be omitted. The adjusting body can be arranged on the top, bottom or any side in the width direction of the base body 110. The adjusting body can be a sliding groove, and the base body 110 is slidably connected in the sliding groove. The sliding grooves can be nested and slidably connected with each other. Specifically, the sliding grooves can be slidably connected through the cooperation of the long holes and the shafts, or can be slidably connected through the cooperation structures such as the guide rails and the guide grooves. In this case, the connection line from one end to the other end in the length direction of the moving plate 510 can extend to the first mounting plate 120 to avoid the first mounting plate 120 interfering with the movement of the adjusting body. Of course, this is not restrictive. The adjusting body can be of other shapes. For example, the adjusting body is a straight plate, which can be arranged on the top or bottom of the base body, as long as the adjusting bodies can be telescopically arranged between each other, one side of the adjusting body is fixedly or slidably connected to the base body, and the other side of the adjusting body is connected to the second mounting plate. These adjustments do not deviate from the principle of the present application and are within the protection scope of the present application.

[0073] Possibly, both the first foot 810 and the second foot 820 are fixed feet, which facilitates the upgrading of existing household appliances. It can be understood that a fixed foot refers to a foot that cannot be telescoped. Specifically, the fixed foot includes a support pad and a threaded rod. One end of the threaded rod is connected to one side of the support pad, and the other end of the threaded rod passes through the corresponding mounting plate and is connected to the bottom of the household appliance. The support pad is used to contact a reference surface such as the ground. Among them, a fastening nut can be sleeved on the threaded rod. For the first foot 810, the fastening nut can be clamped between the support pad and the second mounting plate 132. For the second foot 820, the fastening nut can be clamped between the support pad and the annular rib 1412. Alternatively, the threaded rod can be replaced with a rod without threads, and a buckle can be provided at the end of the rod. A card slot is provided at the bottom of the household appliance, and the fastening connection with the bottom of the household appliance is realized through the clamping of the buckle and the card slot.

[0074] Alternatively, the first foot 810 and / or the second foot 820 is a telescopic foot, and the telescopic foot is used to automatically level the household appliance. When the user needs to move the household appliance, the moving mechanism can be lowered, so that the household appliance can be moved through the moving mechanism. After stopping the movement, the moving mechanism can be raised and retracted. After the telescopic foot contacts the ground, a leveling operation is performed to ensure that the device immediately returns to a stable state without any additional operations, and the household appliance can be seamlessly switched between the moving state and the foot support state.

[0075] Specifically, the first foot 810 is a telescopic foot, and the telescopic foot can be connected to the first mounting hole 121 and / or the second mounting hole 1321 through a screw rod. The second foot 820 is a fixed foot. This makes the fixed foot located at the front side of the household appliance and the telescopic foot located at the rear side of the household appliance after the moving mechanism is installed. During the use of the household appliance, since the front part of the household appliance is a fixed foot, the front part is more stable, which can reduce the risk of damage to the front foot caused by bumps, etc. The telescopic foot at the rear side provides flexibility and can adjust the height according to actual needs, so that the household appliance can operate stably in various scenarios.

[0076] The number of moving mechanisms in this application is multiple. Taking two as an example for introduction, the two moving mechanisms are arranged on opposite sides of the bottom plate of the household appliance and can both be arranged along the front-rear direction of the household appliance. The number of roller assemblies 200 on each moving mechanism can be multiple. Taking two as an example for introduction, the two roller assemblies 200 are spaced apart and are both rotatably connected to the guide groove through a connecting arm 220. A pushing structure 400 is provided at the position corresponding to each roller assembly 200 on the pushing section 512.

[0077] As a possible implementation, the top of the base body 110 of the present application has a bump 700, and the bump 700 is used to fill the gap between the base 100 and the bottom of the household appliance. After the moving mechanism is installed at the bottom of the household appliance, since the bottom of the household appliance may not be flat, there may be a gap between the base body 110 and the bottom of the household appliance, and the connection part between the adjusting body 131 and the base body 110 is also relatively weak, so that the moving mechanism may not be able to withstand the force of the household appliance and deform. Therefore, in the present application, a bump 700 is filled in the gap between the base body 110 and the bottom of the household appliance, and the base 100 bears this force through the bump 700, which is equivalent to completely relying on the base body 110 to bear the force, rather than letting the adjusting member 130 bear the force. Even if the adjusting member 130 is designed to be more fragile, the moving mechanism will not deform.

[0078] As a possible implementation, the region where the positive projection of the bump 700 on the rear roller assembly 200 is located between the connection position on the base body 110 and the pushing structure 400, that is, the region between the fourth shaft 240 and the pushing structure 400. In practical applications, the applicant found that the rear roller assembly 200 is subjected to a large force. By arranging the bump 700 at the rear roller assembly 200, the deformation of the base 100 can be effectively avoided, and the stability of the moving mechanism can be improved. Further, the bump 700 is also arranged at the front roller assembly 200, and the region where the positive projection of the bump 700 on the front roller assembly 200 is located between the connection position on the base body 110 and the pushing structure 400 is used to further avoid the deformation of the moving mechanism.

[0079] Among them, the bump 700 can be integrally formed with the base body 110 or can be separately arranged. In the case where the bump 700 and the base body 110 are of a split structure, the bump 700 can be fixedly connected to the base body 110 by means of bonding, welding or bolt connection, etc.; in the case where the bump 700 and the base body 110 are of an integrally formed structure, the bump 700 and the base body 110 can be formed by stamping. Possibly, in the case where the bump 700 and the base body 110 are of a split structure, an installation groove is provided on the top surface of the base body 110, and the bump 700 is installed in the installation groove. Among them, the bump 700 can be bonded to the base body 110, and a felt is provided on the top surface to achieve the purpose of vibration reduction. The convex structure can be a hollow structure, so as to improve the anti-deformation ability and the ability to resist vibration.

[0080] Possibly, a torsion spring is sleeved on the fourth shaft 240, and both ends of the torsion spring abut against the moving plate 510. For example, both ends of the torsion spring extend and abut against the moving plate 510 on opposite sides of the fourth shaft 240. Since the torsion spring is sleeved on the fourth shaft 240 connected to the guiding groove and both ends thereof abut against the moving plate 510, the torsion spring can apply a force to both the fourth shaft 240 and the moving plate 510 simultaneously, thereby enabling the pressing together of the moving groove and the guiding groove and avoiding problems such as resonance noise.

[0081] It should be noted that although this application is introduced by taking the example of a torsion spring sleeved on the fourth shaft 240. However, this is not intended to limit the protection scope of this application. The torsion spring can be replaced with other pressing structures as long as they can abut against the moving plate 510. Changes in their specific forms do not deviate from the principle of this application. For example, the pressing structure is set as an elastic hollow cylinder, and the hollow cylinder abuts against the moving plate 510, etc. These adjustments do not deviate from the principle of this application and are all within the protection scope of this application.

[0082] The possible implementation manners of the telescopic feet will be introduced below.

[0083] As Figure 5 shown, the number of telescopic feet is at least two. The telescopic feet include a foot base 811, an adjusting foot 812, and a telescopic cavity 813. The foot base 811 is installed on the second mounting plate 132 and is sleeved on the adjusting foot 812. The adjusting foot 812 is axially movably arranged along the foot base 811. The adjusting foot 812 has a receiving cavity 8121. The telescopic cavity 813 is arranged in the receiving cavity 8121 and is configured to drive the adjusting foot 812 to move. The telescopic cavities 813 of at least two telescopic feet are connected through a communication structure 814. These two telescopic feet can be respectively arranged on two moving mechanisms. The communication structure 814 can be a pipe or a pipe and a liquid storage tank that are interconnected, etc. Among them, the telescopic cavity 813 can be a corrugated cavity made of a flexible material, but this is not restrictive. The telescopic cavity 813 can also be a rubber bladder, etc. The telescopic cavity 813 can be fixedly or contact-connected to the inner wall corresponding to the receiving cavity 8121 and abut against the foot base 811.

[0084] Among them, the telescopic cavity 813 can be filled with a hydraulic medium. Under the action of pressure, the hydraulic medium can flow between the interconnected telescopic cavities 813. When the ground is uneven, different pressures are generated due to the unevenness. The fluidity of the hydraulic medium enables adaptive adjustment of the telescopic length between the telescopic cavities 813, thereby driving the adjusting foot 812 to perform adaptive telescoping relative to the foot base 811. After the hydraulic medium stops flowing, automatic leveling of the telescopic feet can be achieved.

[0085] The manner in which the respective telescopic cavities 813 communicate through the communication structure 814 may be as follows: Each foot base 811 is provided with a liquid passage 8111, each telescopic cavity 813 has a liquid passing port, the liquid passing port of each telescopic foot is connected to one end of the liquid passage 8111, and the other ends of the liquid passages 8111 of each telescopic foot communicate through the communication structure 814. Possibly, an installation groove is formed inside the foot base 811, a first limiting ring protruding inward is provided at the notch of the installation groove, and a second limiting ring is provided on the outer wall of the adjusting foot 812. The second limiting ring is located above the first limiting ring so that the first limiting ring provides limitation to prevent the adjusting foot 812 from falling off.

[0086] It should be noted that although the telescopic feet of the present application are described by taking hydraulic feet as an example, this is not intended to limit the protection scope of the present application. As long as the telescopic feet have the function of automatic leveling, they can be any existing or future possible structures. For example, the telescopic feet are configured as electric telescopic feet, that is, the feet are driven to expand and contract by a motor and a transmission assembly. The motor can be a small DC motor or a stepping motor. The motor is installed at a specific position at the bottom of the household appliance, and its stability is ensured through a fixed bracket. The output shaft of the motor is connected to the transmission assembly. The transmission assembly can be a gear set or a lead screw nut mechanism. If it is a lead screw nut mechanism, the motor drives the lead screw to rotate, and the nut is connected to the foot. As the lead screw rotates, the nut moves up and down along the lead screw, thereby driving the foot to expand and contract. In order to achieve the automatic leveling function, a corresponding control circuit and sensors can be equipped. The sensors can detect the horizontal state of the household appliance, such as a gyroscope, an acceleration sensor, etc. These sensors transmit information such as the tilt angle of the household appliance to the control circuit. The control circuit determines whether the household appliance is in a horizontal state according to the signals of the sensors and controls the operation of the motor to adjust the length of the feet until the household appliance reaches a horizontal state.

[0087] On the other hand, the present application also provides a household appliance system, which includes the moving mechanism described in any of the above embodiments, and further includes a household appliance. The base 100 is installed at the bottom of the household appliance. It should be noted that the above-described installation at the bottom of the household appliance may be on the bottom plate at the bottom of the household appliance.

[0088] It should be noted that the above embodiments are only used to illustrate the principle of the present application and are not intended to limit the protection scope of the present application. Without departing from the principle of the present application, those skilled in the art can adjust the above structure so that the present application can be applied to more specific application scenarios.

[0089] For example, as an alternative embodiment, although this application is introduced by taking the two ends of the groove 142 penetrating in the width direction of the household appliance as an example, this is not intended to limit the protection scope of this application. For example, the end of the groove 142 close to the edge of the household appliance in the width direction is blocked, and the opposite end penetrates, etc. These adjustments do not deviate from the principle of this application and are all within the protection scope of this application.

[0090] For example, as an alternative embodiment, the side wall of the guiding groove can protrude from the side wall of the moving groove, and the fourth shaft 240 crosses the side wall of the moving groove to be connected to the side wall of the guiding groove. In this case, the setting of the second strip-shaped hole can be omitted. In addition, the guiding groove can have a notch only on one side, the moving groove can have an inclined groove only on one side, one end of the third shaft 230 is located in the notch and the inclined groove, and the other end is located inside the moving groove. These adjustments do not deviate from the principle of this application and are all within the protection scope of this application.

[0091] For example, as an alternative embodiment, although this application is introduced by taking the second shaft provided on the second connecting portion 630 and the guiding hole provided on the second extending section 5112 as an example, this is not intended to limit the protection scope of this application. For example, the guiding hole is provided on the second connecting portion 630, and the second shaft is provided on the second extending section 5112. These adjustments do not deviate from the principle of this application and are all within the protection scope of this application.

[0092] For example, as an alternative embodiment, although this application is introduced by taking the fourth shaft 240 rotatably connected to the side wall of the guiding groove as an example, this is not intended to limit the protection scope of this application. For example, an avoidance groove is provided at the bottom of the moving groove, a third shaft hole is provided at the position of the guiding groove corresponding to the avoidance groove, and the fourth shaft 240 is rotatably connected in the third shaft hole. These adjustments do not deviate from the principle of this application and are all within the protection scope of this application.

[0093] For example, as an alternative embodiment, the second extending section 5112 may not cross the protruding portion 143, and the second connecting portion 630 of the handle structure 600 covers the protruding portion 143 and is connected to the second extending section 5112.

[0094] For example, as an alternative embodiment, the handle structure 600 includes a handle portion 610 and a driving portion, so that the handle portion 610 drives the moving groove to reciprocate in the guiding groove through the driving portion. Among them, the driving portion can be a link mechanism, a cam mechanism, a gear rack mechanism, a crank mechanism, etc. These adjustments do not deviate from the principle of this application and are all within the protection scope of this application.

[0095] For example, as an alternative embodiment, the setting of the first vertical plate 520 and / or the second vertical plate 530 can be omitted. At least one of the bump 700, the gasket 300, the annular rib 1412, and the groove 142 can be omitted.

[0096] For example, as an alternative embodiment, the base body 110 may also not have a guide groove, and the guide groove is replaced with a straight plate structure. Columns are provided on opposite sides of the straight plate structure, and the connecting arm 220 of the roller assembly 200 is rotatably connected to the columns through the fourth shaft 240.

[0097] For example, as an alternative embodiment, the setting of the handle structure 600 can be omitted, and the user uses a tool or directly manually drives the moving plate 510.

[0098] For example, as an alternative embodiment, although the above is described by taking the first mounting hole 121 and the second mounting hole 1321 as strip-shaped holes arranged along the length direction as an example. However, this is not intended to limit the protection scope of the present application. As long as when the second mounting plate 132 retracts, the first mounting hole 121 and the second mounting hole 1321 have an overlapping part, and when the second mounting plate 132 extends, the second mounting hole 1321 has a part independent of the first mounting hole 121. For example, alternatively, the number of the first mounting holes 121 and the second mounting holes 1321 is a plurality of round holes, and each first mounting hole 121 is arranged at intervals along the length direction of the base body 110, and each second mounting hole 1321 is arranged at intervals along the length direction of the base body 110, so that when the second mounting plate 132 retracts, some of the first mounting holes 121 and some of the second mounting holes 1321 overlap, and the first foot 810 is installed through one group of overlapping parts, and when the second mounting plate 132 extends, the second mounting hole 1321 has a part independent of the first mounting hole 121, and the first foot 810 is installed through the second mounting hole 1321 independent of the first mounting hole 121.

[0099] For example, as an alternative embodiment, the setting of the first mounting hole 121 and the second mounting hole 1321 can be omitted. In this case, the first foot 810 is clamped and fixed to the bottom of the household appliance with the first mounting plate 120 and / or the second mounting plate 132. As long as when the second mounting plate 132 retracts, at least one of the first mounting plate 120 and the second mounting plate 132 is for installing the first foot 810 in the foot assembly, and when the second mounting plate 132 extends, the second mounting plate 132 is for installing the first foot 810. These adjustments do not deviate from the principle of the present application and are all within the protection scope of the present application.

[0100] For example, as an alternative embodiment, the pushing structure and the moving plate can be omitted. In this case, the roller assembly can include rollers and a transmission assembly, and the moving mechanism further includes a motor. The motor is in transmission connection with the rollers through the transmission assembly to drive the rollers to move up and down through the motor and the transmission assembly. As long as the moving mechanism is configured such that when the roller assembly is in the lowered state, the roller assembly can support the household appliance, and when the roller assembly is in the raised state, the feet assembly at the bottom of the household appliance can support the household appliance, these possible adjustments do not deviate from the principle of the present application and are all within the protection scope of the present application.

[0101] For example, as an alternative embodiment, the base body is provided with a plurality of card slots arranged along its length direction, and the adjusting body has catches corresponding to each card slot one by one along its length direction. The catches can be snap-connected to any card slot.
