The pushing structure 400 of the present application is arranged on the pushing section 512, and 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 that the roller assembly 200 supports the household appliance, and facilitates movement of the household appliance through rotation of the roller 210.

[0037] 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 guide groove should comprise a plate body and third and fourth vertical plates arranged on both sides of the plate body in the width direction, and the third and fourth vertical plates and the plate body form the above-mentioned guide groove. The guide groove is preferably a U-shaped groove, but can also be replaced by a guide groove with one end blocked and the other end open in the length direction, and the like.

[0039] It should be noted that the above introduction is only exemplary, as long as the roller assembly 200 can be lifted, the specific setting mode can be adjusted. For example, the roller 210 can be provided with 1 or more than 2, and the "roller 210 is rotatably connected to the opposite ends of the third shaft 230" is replaced by "the roller 210 is rotatably connected to the middle part of the third shaft 230", in this case, the first shaft holes of the two connecting arms 220 can be fixed at both ends of the third shaft 230, and the roller 210 can be located in the guide groove.

For example, the fourth shaft 240 is rotatably fixed in the second shaft hole, and the fourth shaft 240 is rotatably connected with the side of the guide groove. For example, the number of the connecting arms 220 can be provided with 1 or more than 2.

[0040] Referring to Figure 3 The bottom of the household appliance has a protruding extension edge 900, which can be located near one side of the door body of the household appliance, that is, the front side of the household appliance, and 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 plate of the household appliance, etc. The extension edge 900 is fixedly connected with the bottom plate of the household appliance, for example, the bottom plate has a flange, the flange is attached to the extension edge 900 and is fixed by bolt connection, welding or the like, thereby enhancing the structural strength of the household appliance and improving the overall stability. The extension edge 900 can also protect the components at the bottom of the household appliance, effectively preventing external objects from damaging or scratching the structure at the bottom of the household appliance, and can also serve as a decorative plate, etc.

[0041] Possibly, the moving mechanism of the present application further comprises a handle structure 600, the third mounting plate 140 has a groove 142 on the top surface extending along the width direction of the base body 110, the groove 142 extends to the bottom surface of the third mounting plate 140 to form a protruding part 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 are through, used to accommodate the extended edge 900 described above, to ensure that the base 100 is horizontally installed at the bottom of the household appliance, and avoid that the moving mechanism is blocked due to inclination or instability. In addition, the moving plate 510 of the present application has a bending section 511 on the 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 is bent away from the base 100 from the pushing section 512, the second extension section 5112 is bent from the first extension section 5111 to the protruding part 143, and beyond the protruding part 143, the handle structure 600 is connected with the part of the second extension section 5112 beyond the protruding part 143, to facilitate the user to hold the handle part 610 from the front of the household appliance, so as to drive the moving plate 510 to reciprocate.

[0042] The handle structure 600 of the present application has a handle part 610, a first connecting part 620 and a second connecting part 630 provided on the handle part 610, the first connecting part 620 is rotatably connected with the third mounting plate 140 through a first shaft, the second connecting part 630 is provided with a second shaft, the second extension section 5112 is provided with a guide hole (which can be a long hole), and the second shaft is movably arranged in the guide hole. The end of the second shaft can be provided with a limiting block to prevent the second shaft from being pulled out of the guide 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 on 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.

[0043] The working principle of the moving mechanism of the present application is introduced as follows. When the rollers 210 need to be lowered to move the household appliance, the handle portion 610 is turned by a certain angle, so that the moving groove moves smoothly along the first direction (e.g. forward) under the guidance of the guide groove, and 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 turns away from the base body 110, the rollers 210 are lowered 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 rollers 210 in the roller assembly 200. When the roller assembly 200 needs to be raised and retracted, the handle portion 610 is turned in the opposite direction by a certain angle, so that the moving groove moves smoothly along the second direction opposite to the first direction (e.g. backward) under the guidance of the guide groove, and the pushing structure 400 moves away from the roller assembly 200, so that the roller assembly 200 can be raised and retracted, and at this time, the foot assembly of the household appliance contacts the ground.

[0044] In the present application, the specific form of the pushing structure 400 is not limited. Two possible embodiments are introduced as follows.

[0045] In the first possible embodiment, the pushing structure 400 is a wedge-shaped block having an inclined surface, which is arranged towards the roller assembly 200 and connected to the moving plate 510 at one end, 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 turn away from the moving plate 510. When the moving plate 510 moves in the opposite direction, the wedge-shaped block moves away from the roller assembly 200, so that the roller assembly 200 can be retracted.

[0046] In the second possible embodiment, the pushing structure 400 is arranged as an inclined groove provided on the first vertical plate 520 and the second vertical plate 530, the opposite two side walls of the guide groove each have a vertically arranged notch, and the two ends of the third shaft 230 are respectively arranged in the two notches and the two inclined grooves. In this case, the rollers 210 can be located outside the guide groove, and the connecting arm 220 can be located inside the moving groove. This arrangement allows the roller assembly 200 to gradually descend and expand under the guidance of the inclined wall of the inclined groove when the moving plate 510 moves along the first direction, until the rollers 210 contact the ground. When the moving plate 510 moves in the opposite direction, the inclined wall of the inclined groove moves away from the roller assembly 200, so that the roller assembly 200 can be retracted. The purpose of arranging the notches is not only to avoid interference, but also to provide a precise movement path for the third shaft 230, effectively avoiding deviation and misalignment due to loose rotation, thereby ensuring the smoothness and stability of the expansion and retraction actions of the roller assembly 200.

[0047] It can be understood that the side wall of the guide groove is provided with a vertical notch, that is, the notch is through from the side of the guide groove close to the groove bottom to the side of the guide groove away 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 along the vertical direction.

[0048] The moving mechanism of the present application further comprises an adjusting member 130, which comprises 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 be telescoped relative to the first mounting plate 120. When the second mounting plate 132 is retracted, at least one of the first mounting plate 120 and the second mounting plate 132 is provided for mounting the first foot 810 in the foot assembly. When the second mounting plate 132 is extended, the second mounting plate 132 is provided for mounting the first foot 810.

[0049] Specifically, the second mounting plate 132 is stacked on the first mounting plate 120, and the first mounting plate 120 has a first mounting hole 121, and the second mounting plate 132 has a second mounting hole 1321. Possibly, the first mounting hole 121 and the second mounting hole 1321 are both strip-shaped holes arranged along the length direction of the base body 110. When the second mounting plate 132 is retracted, the first mounting hole 121 and the second mounting hole 1321 have an overlapping portion for the first foot 810 to pass through. When the second mounting plate 132 is extended, 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.

[0050] When the moving mechanism is applied to a household appliance with small depth, the adjusting body 131 can be moved inward to the base body 110, so that the second mounting plate 132 is retracted to an initial position, which can or can not protrude from the first mounting plate 120, and the application does not limit it. At this time, the first mounting hole 121 and the strip-shaped hole of the second mounting hole 1321 have an overlapping part, forming an overlapping mounting area, and the user can flexibly select the best mounting point within the length range of the overlapping mounting area according to the structure of the household appliance bottom disc, so that the first foot 810 passes through the overlapping part and is fixed at the bottom of the household appliance, and the superposition structure formed by the double-layer mounting plate significantly improves the pressure stability. For a household appliance with large depth, the adjusting body 131 is moved outward to extend, so that the second mounting plate 132 is fully deployed. 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 the large household appliance, but also ensures that the first foot 810 is precisely positioned and installed within a larger span range. In summary, the above setting mode is not only suitable for 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 structure is needed, thereby improving space utilization, simplifying the manufacturing process and improving installation convenience.

[0051] As a possible implementation, the second mounting plate 132 is stacked on the bottom of the first mounting plate 120, and the moving mechanism further includes a gasket 300, which is arranged on the top of the second mounting plate 132 outside the first mounting plate 120 when the second mounting plate 132 is extended. 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 protruding from the top of the base body 110, thereby ensuring the horizontal installation of the moving mechanism. At the same time, since the gasket 300 is arranged on the top of the second mounting plate 132 outside the first mounting plate 120 when the second mounting plate 132 is extended, the gasket 300 can fill the gap between the second mounting plate 132 and the bottom of the household appliance, thereby reducing or avoiding 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, a double-layer superposition structure is formed when the second mounting plate 132 is extended, which significantly improves the pressure stability. The gasket 300 has shock-absorbing felt on one or both sides in the thickness direction, which avoids resonance noise with the shell of the household appliance.

[0052] As a possible implementation, the two side walls of the guide groove are provided with a first slot 111 arranged along the length direction of the guide groove, the adjusting body 131 is arranged at the bottom of the base body 110, the adjusting body 131 is provided with a sliding groove 1311, the guide groove is located in the sliding groove 1311, and the two side walls of the sliding groove 1311 are connected with a connecting shaft 133, and the connecting shaft 133 is arranged in the first slot 111 on the two side walls of the guide groove. Further, the adjusting body 131 is also provided with a connecting plate 1312, the connecting plate 1312 is attached to the side wall of the guide groove, one end of the connecting plate 1312 is connected to the side wall of the sliding groove 1311, and the other end is connected to the second mounting plate 132, so as to avoid affecting the lifting of the roller assembly 200. The connecting plate 1312 and the side wall of the sliding groove 1311 can be located in the same plane, and can be arranged perpendicularly to the second mounting plate 132, or at an angle, etc. Among them, the adjusting body 131, the connecting plate 1312 and the sliding groove 1311 are preferably integrally formed. Further, the first vertical plate 520 and the second vertical plate 530 are provided with a third slot arranged along the length direction of the guide groove, the third slot overlaps with the first slot 111, and the connecting shaft 133 is also located in the first slot 111 and the third slot.

[0053] The adjusting body 131 is arranged at the bottom of the base body 110, avoiding the adjusting body 131 from constituting a protruding part at the top of the base body 110, thereby ensuring the horizontal installation of the moving mechanism. In addition, the nested cooperation of the sliding groove 1311 and the guide groove forms a double-layer guide system, and the sliding track of the connecting shaft 133 in the first slot 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, avoiding deviation or twisting. The symmetrical track formed by the two first slots 111 makes the adjusting body 131 uniformly stressed when stretching and contracting, effectively preventing structural jamming.

[0054] As a possible implementation, the base 100 further comprises a third mounting plate 140, the third mounting plate 140 is arranged at the other end in the length direction of the base body 110, the third mounting plate 140 is preferably integrally formed with the base body 110, and the third mounting plate 140 is provided with a third mounting hole 1411, the third mounting hole 1411 is used for mounting 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 moving mechanism is fixed through the original foot of the household appliance. That is, the moving mechanism of the present application can not only be fixed through the original foot of the household appliance, but also be applicable to different models of household appliances.

[0055] As a possible implementation, the third mounting hole 1411 has an annular protrusion 1412 at the bottom, which 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, and ensure the fastening between the feet and the base 100, so as to effectively bear the weight of the household appliance and the vibration in use. The third mounting hole 1411 can be located between the protruding portion 143 and the guide groove, so that the second foot 820 is located within the extension edge 900, so as to effectively protect the second foot 820 in the front from damage due to bumping by the extension edge 900.

[0056] As a possible implementation, the third mounting plate 140 has a first portion 141, and the third mounting hole 1411 is arranged on the first portion 141. The first portion 141 and the first mounting plate 120 are located on the same side of the base body 110 in the width direction. Thus, not only can the movement of the moving plate 510 be avoided, but also when the moving mechanism is installed on both sides of the household appliance in the width direction, the width between the first feet 810 on both sides is consistent with the width between the second feet 820 on both sides, thereby improving the support stability.

[0057] As an alternative implementation, the number of adjustment bodies is at least two, and each adjustment body is telescopic. One side of the adjustment body is fixed or slidingly connected to the base body, and the other side of the adjustment body is connected to the second mounting plate (e.g., integrally formed). In this case, the connecting plate 1312 can be omitted, and the adjustment body can be arranged on the top, bottom, or any side of the base body 110 in the width direction. The adjustment body can be a sliding groove, and the base body 110 is slidingly connected to the sliding groove. Each sliding groove can be nested and slidingly connected, and each sliding groove can be slidingly connected by a long hole and a shaft, or by a guide rail and a guide groove. In this case, the line from one end to the other end of the moving plate 510 can extend to the first mounting plate 120, so as to avoid the interference of the first mounting plate 120 with the movement of the adjustment body. Of course, this is not a limitation, and the adjustment body can have other shapes, such as a straight plate, which can be arranged on the top or bottom of the base body. As long as each adjustment body is telescopic, one side of the adjustment body is fixed or slidingly connected to the base body, and the other side of the adjustment body is connected to the second mounting plate, these adjustments do not deviate from the principles of the present application, and are within the scope of the present application.

[0058] Possibly, the first foot 810 and the second foot 820 are both fixed feet, thereby facilitating upgrading and reconstruction of existing household appliances. It can be understood that the fixed foot refers to a foot that cannot be extended. 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, the other end of the threaded rod passes through the corresponding mounting plate and is connected to the bottom of the household appliance, and the support pad is used to contact the 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, and 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 by a rod body without threads, and the end of the rod body can be provided with a buckle, and the bottom of the household appliance is provided with a clamping groove, and the fastening connection with the bottom of the household appliance is realized through the clamping of the buckle and the clamping groove.

[0059] Alternatively, the first foot 810 and / or the second foot 820 is a telescopic foot, which 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 is moved through the moving mechanism, and after stopping moving, the moving mechanism can be raised and withdrawn, the telescopic foot contacts the ground and performs leveling operation, ensuring that the equipment immediately returns to a stable state without any additional operation, and enabling the household appliance to seamlessly switch between the moving state and the foot support state.

[0060] Specifically, the first foot 810 is a telescopic foot, which can be connected in the first mounting hole 121 and / or the second mounting hole 1321 through a screw rod, and 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 use of the household appliance, the front part is more stable due to the fixed foot at the front part, which can reduce the risk of damage to the front foot caused by bumping, and the telescopic foot at the rear side provides flexibility, which can adjust the height according to actual needs, so that the household appliance can run stably in various scenes.

[0061] The number of moving mechanisms of the present application is multiple, and two are taken as an example for introduction. The two moving mechanisms are arranged on opposite sides of the bottom plate of the household appliance and can be arranged along the front-rear direction of the household appliance. The number of roller assemblies 200 on each moving mechanism can be multiple, and two are taken as an example for introduction. The two roller assemblies 200 are distributed at intervals and are rotationally connected to the guide groove through the connecting arm 220. The pushing segment 512 is provided with a pushing structure 400 at a position corresponding to each roller assembly 200.

[0062] As a possible implementation, the base body 110 has a protrusion 700 on the top thereof, which is used to fill the gap between the base 100 and the bottom of the household appliance. After the moving mechanism is installed on the bottom of the household appliance, there can be a gap between the base body 110 and the bottom of the household appliance due to the unevenness of the bottom of the household appliance, and the part where the adjusting body 131 is connected to the base body 110 is also relatively weak, so that the moving mechanism can be deformed under the force of the household appliance. Therefore, the gap between the base body 110 and the bottom of the household appliance is filled with the protrusion 700, and the base 100 bears the force through the protrusion 700, which is equivalent to bearing the force by the base body 110 instead of the adjusting member 130, so that even if the adjusting member 130 is designed to be weak, the moving mechanism will not be deformed.

[0063] As a possible implementation, the protrusion 700 is projected on the area between the connecting position of the rear roller assembly 200 on the base body 110 and the pushing structure 400, i.e., the area between the fourth shaft 240 and the pushing structure 400. In actual application, the applicant finds that the rear roller assembly 200 bears a larger force, and the protrusion 700 arranged at the rear roller assembly 200 can effectively prevent the base 100 from being deformed and improve the stability of the moving mechanism. Further, the protrusion 700 is also arranged at the front roller assembly 200, and the protrusion 700 is projected on the area between the connecting position of the front roller assembly 200 on the base body 110 and the pushing structure 400, so as to further prevent the moving mechanism from being deformed.

[0064] The protrusion 700 can be integrally formed with the base body 110 or separately arranged. In the case that the protrusion 700 and the base body 110 are separately arranged, the protrusion 700 can be fixedly connected to the base body 110 by bonding, welding or bolt connection. In the case that the protrusion 700 and the base body 110 are integrally formed, the protrusion 700 and the base body 110 can be formed by stamping. Possibly, in the case that the protrusion 700 and the base body 110 are separately arranged, the top surface of the base body 110 is provided with a mounting groove, and the protrusion 700 is arranged in the mounting groove. The protrusion 700 can be bonded to the base body 110, and a felt is arranged on the top surface, so as to achieve the purpose of vibration reduction. The protrusion structure can be a hollow structure, so as to improve the anti-deformation ability and the ability to resist vibration.

[0065] Possibly, a torsion spring is sleeved on the fourth shaft 240, and the two ends of the torsion spring abut against the moving plate 510. For example, the two ends of the torsion spring protrude and abut against the moving plate 510 on the opposite sides of the fourth shaft 240. Since the torsion spring is sleeved on the fourth shaft 240 connected with the guide groove, and the two ends abut against the moving plate 510, the torsion spring can simultaneously exert force on the fourth shaft 240 and the moving plate 510, so that the compression of the moving groove and the guide groove can be realized, and problems such as resonance noise can be avoided.

[0066] It should be noted that although the present application is introduced by taking the torsion spring sleeved on the fourth shaft 240 as an example. However, this is not intended to limit the protection scope of the present application. The torsion spring can be replaced by other compression structures, as long as it can abut against the moving plate 510. The specific form of change does not deviate from the principle of the present application. For example, the compression structure is set to a hollow cylinder with elasticity, which abuts against the moving plate 510, etc. These adjustments do not deviate from the principle of the present application and are within the protection scope of the present application.

[0067] The possible implementation of the telescopic foot will be introduced below.

[0068] As shown in Figure 5 The number of telescopic feet is at least two. The telescopic foot includes a foot seat 811, an adjusting foot 812, and a telescopic cavity 813. The foot seat 811 is installed on the second mounting plate 132 and sleeved on the adjusting foot 812. The adjusting foot 812 is movably arranged along the axis of the foot seat 811. The adjusting foot 812 has a containing cavity 8121. The telescopic cavity 813 is arranged in the containing cavity 8121 and is arranged to drive the adjusting foot 812 to move. The telescopic cavities 813 of the at least two telescopic feet are communicated through a communication structure 814. The two telescopic feet can be arranged on two moving mechanisms respectively. The communication structure 814 can be a pipe or a pipe and a liquid storage tank that are in communication with each other. The telescopic cavity 813 can be a corrugated cavity of flexible material, but this is not a limitation. The telescopic cavity 813 can also be a rubber capsule. The telescopic cavity 813 can be fixed or in contact with the inner wall of the containing cavity 8121 and abut against the foot seat 811.

[0069] The telescopic cavity 813 can be filled with hydraulic medium. Under the action of pressure, the hydraulic medium can flow between the telescopic cavities 813 in communication. When the ground is uneven, different pressures are generated due to unevenness. The flowability of the hydraulic medium enables the telescopic cavities 813 to adaptively adjust and expand or contract, thereby driving the adjusting foot 812 to adaptively expand or contract relative to the foot seat 811. After the hydraulic medium stops flowing, the telescopic foot can automatically level.

[0070] The communication between the respective telescopic cavities 813 through the communication structure 814 can be that the respective bottom foot bases 811 are provided with liquid passages 8111, the respective telescopic cavities 813 have liquid passages, the liquid passages of each telescopic bottom foot are connected with one end of the liquid passages 8111, and the other end of the liquid passages 8111 of each telescopic bottom foot is communicated through the communication structure 814. Possibly, the bottom foot base 811 is formed with a mounting groove, the groove of the mounting groove is provided with a first limiting ring protruding inwardly, and the outer wall of the adjusting foot 812 is provided with a second limiting ring, which is located on the upper side of the first limiting ring, so that the first limiting ring provides limiting to avoid the falling of the adjusting foot 812.

[0071] It should be noted that although the telescopic bottom foot of the present application is described by taking the hydraulic bottom foot as an example, this is not intended to limit the protection scope of the present application, as long as the telescopic bottom foot has the function of automatic leveling, it can be any structure of the existing and future possible. For example, the telescopic bottom foot is composed of an electric telescopic bottom foot, that is, the bottom foot is driven to telescope through 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 the stability thereof is ensured through a fixed support, the output shaft of the motor is connected with the transmission assembly, and the transmission assembly can be a gear set or a screw nut mechanism. If it is a screw nut mechanism, the motor drives the screw to rotate, the nut is connected with the bottom foot, and with the rotation of the screw, the nut moves up and down along the screw, thereby driving the bottom foot to telescope. In order to realize the automatic leveling function, a corresponding control circuit and sensor can be provided. The sensor can detect the horizontal state of the household appliance, such as a gyroscope, an acceleration sensor, etc. These sensors transmit information such as the inclination angle of the household appliance to the control circuit, the control circuit judges whether the household appliance is in a horizontal state according to the signal of the sensor, and controls the operation of the motor to adjust the length of the bottom foot until the household appliance reaches the horizontal state.

[0072] In another aspect, the present application also provides a household appliance system, which comprises the moving mechanism of any of the above-mentioned embodiments, and further comprises a household appliance, and the base 100 is installed at the bottom of the household appliance. It should be noted that the above-mentioned installation at the bottom of the household appliance can be installed on the bottom plate at the bottom of the household appliance.

[0073] It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present application, and are not intended to limit the protection scope of the present application, and those skilled in the art can adjust the above-mentioned structure without departing from the principles of the present application, so that the present application can be applied to more specific application scenarios.

[0074] For example, as an alternative embodiment, although the present application is introduced by taking the example that the recess 142 is through at both ends in the width direction of the household appliance, this is not intended to limit the protection scope of the present application. For example, the end of the recess 142 close to the edge of the household appliance is blocked, and the opposite end is through, etc. These adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0075] For example, as an alternative embodiment, the side wall of the guide groove can protrude from the side wall of the moving groove, the fourth shaft 240 is connected to the side wall of the guide groove beyond the side wall of the moving groove, in which case the second slot hole can be omitted. In addition, the guide groove can have a notch on only one side, the moving groove can have an inclined groove on only 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 principles of the present application and are within the protection scope of the present application.

[0076] For example, as an alternative embodiment, although the present application is introduced by taking the example that the second connecting part 630 is provided with a second shaft and the second extension section 5112 is provided with a guide hole, this is not intended to limit the protection scope of the present application. For example, the second connecting part 630 is provided with a guide hole, and the second extension section 5112 is provided with a second shaft. These adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0077] For example, as an alternative embodiment, although the present application is introduced by taking the example that the fourth shaft 240 is rotatably connected to the side wall of the guide groove, this is not intended to limit the protection scope of the present application. For example, the groove bottom of the moving groove is provided with a relief groove, the guide groove is provided with a third shaft hole at a position corresponding to the relief groove, and the fourth shaft 240 is rotatably connected to the third shaft hole. These adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0078] For example, as an alternative embodiment, the second extension section 5112 can not pass beyond the protruding part 143, and the second connecting part 630 of the handle structure 600 covers the protruding part 143 and is connected to the second extension section 5112.

[0079] For example, as an alternative embodiment, the handle structure 600 includes a handle part 610 and a driving part, so that the handle part 610 is driven by the driving part to move the moving groove reciprocatingly in the guide groove. The driving part can be a connecting rod mechanism, a cam mechanism, a gear and rack mechanism, a crank mechanism, etc. These adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0080] For example, as an alternative embodiment, the first vertical plate 520 and / or the second vertical plate 530 can be omitted. At least one of the protrusion 700, the gasket 300, the annular protrusion 1412, and the groove 142 can be omitted.

[0081] For example, as an alternative embodiment, the base body 110 can also not have the guide groove, and the guide groove is replaced by a straight plate structure, and a vertical column is arranged on opposite sides of the straight plate structure, and the connecting arm 220 of the roller assembly 200 is rotationally connected to the vertical column through the fourth shaft 240.

[0082] For example, as an alternative embodiment, the handle structure 600 can be omitted, and the user drives the moving plate 510 by using a tool or directly manually.

[0083] 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 the first mounting hole 121 and the second mounting hole 1321 have an overlapping portion when the second mounting plate 132 is retracted, and the second mounting hole 1321 has a portion independent of the first mounting hole 121 when the second mounting plate 132 is extended. For example, alternatively, the first mounting hole 121 and the second mounting hole 1321 are both a plurality of circular holes, each first mounting hole 121 is arranged along the length direction of the base body 110, each second mounting hole 1321 is arranged along the length direction of the base body 110, so that part of the first mounting hole 121 and part of the second mounting hole 1321 overlap when the second mounting plate 132 is retracted, and the first foot 810 is mounted through one set of overlapping portions, and the second mounting hole 1321 has a portion independent of the first mounting hole 121 when the second mounting plate 132 is extended, and the first foot 810 is mounted through the second mounting hole 1321 independent of the first mounting hole 121.

[0084] For example, as an alternative embodiment, 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 by the first mounting plate 120 and / or the second mounting plate 132. As long as at least one of the first mounting plate 120 and the second mounting plate 132 is provided for mounting the first foot 810 in the foot assembly when the second mounting plate 132 is retracted, and the second mounting plate 132 is provided for mounting the first foot 810 when the second mounting plate 132 is extended. These adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0085] For example, as an alternative embodiment, the pushing structure and the moving plate can be omitted, in which case the roller assembly can include a roller and a transmission assembly, and the moving mechanism further includes a motor, which is in driving connection with the roller through the transmission assembly, so as to drive the roller to move up and down through the motor and the transmission assembly. As long as the moving mechanism is arranged to support the household appliance when the roller assembly is in the lowered state and to support the household appliance through the foot assembly at the bottom of the household appliance when the roller assembly is in the raised state, these possible adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0086] For example, as an alternative embodiment, the base body has a plurality of clamping grooves arranged along the length direction thereof, and the adjusting body has a clamping buckle corresponding to each clamping groove along the length direction thereof, and the clamping buckle can be clamped with any clamping groove. As long as the adjusting body can be adjusted in position along the length direction of the base body, the specific embodiments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0087] For example, as an alternative embodiment, the first mounting plate 120 can be located at the top of the base body. For example, the line extending from one end to the other end of the length direction of the moving plate 510 can extend to the first mounting plate 120, and the like, and these adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0088] For example, as an alternative embodiment, the base can not be used to mount the foot.

[0089] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without deviating from the principles of the present application, and the technical solutions after these changes or replacements will fall within the protection scope of the present application.
