[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0035] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the liftable base 1 provided in the embodiment of the present application. Figure 2 The exploded schematic diagram of the liftable base 1 provided in the embodiment of the present application. The liftable base 1 provided in the embodiment of the present application is applied to the washing machine, and the liftable base 1 includes: a base 10, a lifting platform 20 and a transmission mechanism 30. Among them, the lifting platform 20 is movably arranged on the base 10, and the transmission mechanism 30 includes a screw 31 and a slider 32, wherein the screw 31 is rotatably arranged on the base 10, and the slider 32 is fixed to the lifting platform 20 and is threadedly connected to the screw 31. When the screw 31 rotates around the axis of the screw 31, the slider 32 rotates relative to the screw 31 to drive the lifting platform 20 to move up and down relative to the base 10 along the axial direction of the screw 31. The liftable base 1 provided in the embodiment of the present application can facilitate the height adjustment of the clothing processing device by converting the rotational motion of the screw 31 into a motion that can drive the lifting platform 20 to move upward or downward relative to the base 10, so as to adapt to the usage habits of different user groups for the clothing processing device.

[0036] See also Figure 3 , Figure 3 The schematic diagram of the structure of the base 10 provided in the embodiment of the present application is as follows. The base 10 includes a plurality of pillars 11 and a plurality of beams for connecting the plurality of pillars 11. Exemplarily, the base 10 may include at least two oppositely arranged cross beams, each cross beam being used to connect between two adjacent pillars 11. For example, the base 10 may include two cross beams and four pillars 11. The two cross beams are oppositely arranged, and the two ends of one of the cross beams are respectively connected to two of the pillars 11, and the two ends of the other cross beam are respectively connected to the other two pillars 11. It is understandable that three, four or even more cross beams may be provided. In addition to some cross beams that are oppositely arranged and connected to the pillars 11, other cross beams may also be connected between two opposite cross beams to connect the four pillars 11 as a whole, so that the four pillars 11 can restrain each other, improve the integrity and structural strength of the base 10, and ultimately improve the stability of the movement of the lifting platform 20. In addition, the pillars 11 may not be limited to four, and may also be provided with five, six or even more. The number of pillars 11 and the distribution positions between the multiple pillars 11 can be designed according to the structure of the lifting platform 20, the weight of the clothing processing equipment and the load of the clothing processing equipment.

[0037] In some embodiments, the base 10 may further include a buffer pad 13, which is mounted on the end of the support 11 away from the lifting platform 20. Preferably, the buffer pad 13 can be made of rubber or other suitable soft materials. By sleeve-mounting the soft buffer pad 13 on the end of the support 11 away from the lifting platform 20, the support 11 can be effectively prevented from crushing the supporting surface under the action of a large axial pressure, and the base can also be prevented from generating harsh noise when moving.

[0038] please Figure 3 See also Figure 4 , Figure 4 The structural diagram of the lifting platform 20 provided in the embodiment of the present application. The lifting platform 20 may include a support plate 21 and a plurality of guide pillars 22, wherein the support plate 21 is connected to one end of the plurality of guide pillars 22, and a plurality of pillars 11 of the base 10 are provided with guide channels 111, and the guide pillars 22 may be slidably assembled in the guide channels 111, so that the support plate 21 can move up and down relative to the base 10 along the direction of gravity. For example, in some embodiments, the support plate 21 may be a rectangular structural plate, and four guide posts 22 may be provided, and the four guide posts 22 are respectively provided at the four corners of the rectangular support plate 21, and the guide posts 22 have an outer shape that matches the guide channel 111 of the pillar 11, so that each guide post 22 can be slidably assembled in the guide channel 111 of each pillar 11, thereby, when the transmission mechanism 30 connected between the lifting platform 20 and the base 10 drives the lifting platform 20 to move, the lifting platform 20 can only move up and down relative to the base 10 along the direction of gravity, and the freedom of the lifting platform 20 relative to the base 10 in other directions is limited, thereby ensuring the stability of its movement. Similarly, the guide posts 22 may not be limited to four, and may be provided with five, six or even more, and the number of guide posts 22 and the distribution positions of the plurality of guide posts 22 may be designed according to the structure of the base 10, the weight of the clothing processing device and the load of the clothing processing device.

[0039] See also Figure 5 , Figure 5A cross-sectional schematic diagram of the cooperation between the guide post 22 and the pillar 11 provided in an embodiment of the present application. In some embodiments, within the guide channel 111, the guide post 22 extends toward the surface of the pillar 11 along the direction of gravity to form one of the guide protrusion 112 and the guide groove, and the pillar 11 extends toward the surface of the guide post 22 along the direction of gravity to form the other of the guide groove and the guide protrusion 112, and the guide protrusion 112 is slidably disposed in the guide groove. For example, within the guide channel 111, the surface of the guide column 22 facing the pillar 11 is provided with two parallel flanges 221, and the two flanges 221 extend along the direction of gravity to form a guide groove between the two flanges 221, or in some embodiments, the guide groove can be directly opened along the gravity direction on the surface of the guide column 22 facing the pillar 11, and accordingly, the side surface of the pillar 11 facing the guide groove is provided with a guide protrusion 112 extending along the gravity direction, and the guide protrusion 112 is embedded in the guide groove. When the guide column 22 slides relative to the pillar 11, the guide protrusion 112 is restricted to slide only along the guide groove, thereby reducing the shaking of the guide column 22 during movement and reducing the contact area between the surface of the guide column 22 and the surface of the pillar 11, which is beneficial to reducing the sliding friction and improving the smoothness of the lifting movement.

[0040] See also Figure 1 and Figure 2 In order to limit the relative position of the lifting platform 20 with respect to the base 10 so as to better enable the clothing processing device installed on the lifting platform 20 to be maintained at a desired height position, the liftable base 1 can also include a limiter 40. Accordingly, the support column 11 is provided with a plurality of first limiter holes 113 along the direction of gravity, and the guide column 22 is provided with a plurality of second limiter holes 222 along the direction of gravity. The limiter 40 can be provided with a first limiter hole 113 and a second limiter hole 222. Exemplarily, the limiting member 40 can be a screw or any other suitable component that can penetrate the first limiting hole 113 and the second limiting hole 222 to perform a limiting function. The four pillars 11 of the base 10 can be provided with a plurality of first limiting holes 113 along the gravity direction, and accordingly, each guide column 22 can be provided with at least one second limiting hole 222 along the gravity direction, or, each pillar 11 can be provided with at least one first limiting hole 113, and each guide column 22 can be provided with a plurality of second limiting holes 222, or, each pillar 11 can be provided with a plurality of first limiting holes 113, and each guide column 22 can be provided with a plurality of second limiting holes 222. When any first limiting hole 113 and any second limiting hole 222 are aligned, the limiting member 40 is used to pass through the first limiting hole 113 and the second limiting hole 222 in sequence, so as to avoid the lifting platform 20 from sliding downward under the gravity of the clothing processing device and its load, and maintain the height position of the lifting platform 20 relative to the base 10.

[0041] See also Figure 1 and Figure 4 The lifting platform 20 may further include a plurality of rollers 23. One end of the guide column 22 is connected to the support plate 21 and the other end is connected to the roller 23. A through guide channel 111 is provided in the support column 11. The guide column 22 is slidably assembled in the guide channel 111. When the guide column 22 slides toward one end where the roller 23 is provided, the roller 23 can extend out of the guide channel 111 so that the roller 23 abuts against the supporting surface. Exemplarily, the roller 23 can be a universal wheel. When the transmission mechanism 30 connected between the base 10 and the lifting platform 20 drives the lifting platform 20 to make a descending movement close to the base 10, the roller 23 arranged at the bottom end of the lifting platform 20 will be driven by the lifting platform 20 to move toward the supporting surface, such as the ground, along the guide channel 111 of the pillar 11 until it abuts against the supporting surface. When the transmission mechanism 30 continues to drive the lifting platform 20 to approach the supporting surface, the roller 23 arranged at the bottom end of the lifting platform 20 will pass through the guide channel 111 to be exposed at the other end of the pillar 11 away from the support plate 21. In this case, the liftable base 1 is supported as a whole by the roller 23. When the liftable base 1 needs to be moved to the desired position, it only needs to be pushed or dragged to the target position.

[0042] like Figure 4 , corresponding to the structure of the base 10, the lifting platform 20 may also include a plurality of beams for connecting a plurality of guide posts 22. Exemplarily, the lifting platform 20 may include at least two beams arranged opposite to each other, each beam being used to connect between two adjacent guide posts 22. For example, the lifting platform 20 may include two beams and four guide posts 22. The two beams are arranged opposite to each other, and the two ends of one beam are respectively connected to two of the guide posts 22, and the two ends of the other beam are respectively connected to the other two guide posts 22. It is understandable that the beams may also be provided with three, four or even more beams. In addition to some beams arranged opposite to each other and connecting the guide posts 22, other beams may also be connected between two opposite beams. Such a design may be beneficial to improving the overall structural strength of the lifting platform 20, and ultimately improving the stability of the movement of the lifting platform 20.

[0043] See also Figure 6 , Figure 6The structural schematic diagram of the liftable base 1 provided in the embodiment of the present application shows the connection relationship between the base 10, the lifting platform 20 and the transmission mechanism 30. The transmission mechanism 30 includes a screw 31 and a slider 32. The screw 31 is rotatably arranged on the base 10. The slider 32 is fixed to the lifting platform 20 and is threadedly connected to the screw 31. When the screw 31 rotates around the axis of the screw 31, the slider 32 can rotate relative to the screw 31 to drive the lifting platform 20 to perform lifting motion relative to the base 10 along the axial direction of the screw 31. Exemplarily, the screw 31 can be arranged on the cross beam of the base 10, and the slider 32 can be arranged on the cross beam of the lifting platform 20. Specifically, one end of the screw 31 is provided with two limiting structures 311 axially spaced apart, and the cross beam of the base 10 is provided with a first opening 14. After one end of the screw 31 is inserted into the first opening 14, the two limiting structures 311 clamp the cross beam of the base 10. In this way, the screw 31 can be axially limitedly installed on the cross beam, so that the screw 31 only has the freedom to rotate around its axis. Correspondingly, the slider 32 is provided with a threaded hole, and the cross beam of the lifting platform 20 for fixing the slider 32 can be provided with a second opening 24, and the slider 32 is assembled in the second opening 24, or the slider 32 is fixed to the cross beam and its threaded hole is connected to the second opening 24. The screw 31 and the slider 32 are arranged relative to each other in the direction of gravity, so that the other end of the screw 31 away from the base 10 is screwed to the slider 32. When the screw 31 rotates, the slider 32 converts the rotational motion of the screw 31 into a motion that drives the lifting platform 20 away from or close to the base 10. For example, when the screw 31 rotates clockwise, the slider 32 drives the lifting platform 20 to move upward away from the base 10, and when the screw 31 rotates counterclockwise, the slider 32 drives the lifting platform 20 to move downward close to the base 10.

[0044] See also Figure 6 and Figure 7 , Figure 7 A schematic diagram of the structure of a liftable base 1 provided in another embodiment of the present application. There may be two or more transmission mechanisms 30. When there is only one transmission mechanism 30, the axis of the screw 31 may coincide with the geometric center line of the lifting platform 20, and the geometric center line is colinear with the gravity line after the clothing processing device is installed on the lifting platform 20. In an embodiment in which there are at least two transmission mechanisms 30, at least two transmission mechanisms 30 may be respectively arranged on opposite sides of the base 10, and at least two transmission mechanisms 30 are used to lift the lifting platform 20 on both sides of the lifting platform 20. Thus, the bending moment of the screw 31 caused by external factors such as the gravity of the lifting platform 20 and the clothing processing device can be effectively reduced, thereby ensuring the service life of the transmission mechanism 30 and the effectiveness and stability of the transmission of the transmission mechanism 30.

[0045] In some embodiments, the liftable base 1 further includes a motor (not shown), which is connected to the screw rod 31 to drive the screw rod 31 to rotate. When the height position of the clothing processing device needs to be adjusted, the motor only needs to be connected to the circuit loop, so that the motor drives the screw rod 31 to rotate, thereby causing the lifting platform 20 to perform lifting movements to achieve the purpose of adjusting the height position of the clothing processing device. This design saves physical labor and is suitable for users of different ages, especially for young users and elderly users.

[0046] See also Figure 8 , Figure 8 The structural diagram of the clothing processing device assembly 100 provided in an embodiment of the present application. The clothing processing device assembly 100 includes a clothing processing device 2 and a liftable base 1. The clothing processing device 2 may be, but is not limited to, a washing machine, a dryer, a washer-dryer, and a dehydrator that are commonly used at present. The liftable base 1 is the liftable base 1 provided in any embodiment of the present application. The clothing processing device 2 is mounted on a lift platform 20 of the liftable base 1.

[0047] In order to facilitate a better understanding of the liftable base and clothing processing equipment assembly provided in the embodiments of the present application, the operating steps and implementation principles of the liftable base and clothing processing equipment assembly provided in one of the embodiments of the present application are further described and introduced below in combination with specific usage scenarios.

[0048] When the height of the clothing processing device needs to be adjusted, a wrench can be used or the motor can be powered on to drive the screw to rotate around its axis. When the height of the clothing processing device needs to be adjusted upward away from the base, the screw can be rotated in one direction so that the transmission mechanism can drive the lifting platform to move upward. When the height of the clothing processing device needs to be adjusted downward toward the base, the screw can be rotated in another direction so that the transmission mechanism can drive the lifting platform to move downward. When the clothing processing device needs to be moved horizontally to another position, the screw can be rotated in another direction until the roller is exposed from the support and can fully support the liftable base. At this time, the liftable base can be pushed or dragged to move the clothing processing device to the target position.

[0049] Compared with the traditional base and clothing processing equipment assembly, the beneficial effects of the liftable base and clothing processing equipment assembly provided in the embodiment of the present application are: on the one hand, by converting the rotational motion of the screw into a motion that can drive the lifting platform to move upward or downward relative to the base, the height position of the clothing processing equipment can be easily adjusted to adapt to the usage habits of different user groups for the clothing processing equipment; on the other hand, by connecting the roller to the other end of the guide column separated from the support plate, when the guide column slides toward the end where the roller is provided, the roller can extend out of the guide channel of the pillar so that the roller abuts against the support surface. Therefore, when it is necessary to move the liftable base to the desired position, it is only necessary to push the base to shift to the target position.
