Description

Technical Field

[0001] The present invention relates to the technical field of clothing treatment, and particularly provides a clothing treatment device. Background Art

[0002] Nowadays, with the continuous improvement of people's living standards, people are constantly pursuing a higher quality of life. Clothing treatment devices such as clothing care machines that use high-temperature steam to remove wrinkles from clothes and clothes dryers that use high-temperature dry air to dry clothes are increasingly favored by people.

[0003] Generally, two bottom wheels are provided at the front side of the bottom of the clothing treatment device, and two fixed feet are provided at the rear side of the bottom of the clothing treatment device. When moving the clothing treatment device, a person stands behind the clothing treatment device and lifts the rear part of the clothing treatment device to make the two fixed feet slightly leave the ground, and then pushes the clothing treatment device forward. However, during the process of pushing the clothing treatment device, it is easy for a person's strength to be exhausted and unable to maintain the state where the fixed feet of the clothing treatment device are always off the ground for a long time, and then the situation where the fixed feet contact the ground and wear the fixed feet and the ground occurs when pushing the clothing treatment device. When pushing the clothing treatment device into the closet, the rear part of the clothing treatment device needs to be placed close to the inner side of the closet, so that the clothing treatment device cannot be pushed from the rear of the clothing treatment device, and the clothing treatment device cannot be pushed and moved at the front side of the clothing treatment device.

[0004] In order to facilitate the movement of the clothing treatment device, in the improved clothing treatment device, a foot and a bottom wheel are respectively provided at the four corners of the bottom, and the foot or the bottom wheel is set to be height-adjustable. When it is necessary to move the clothing treatment device, by adjusting the height of the foot or the bottom wheel, the four bottom wheels contact the ground and the four feet leave the ground. When the clothing treatment device moves in place, by adjusting the height of the foot or the bottom wheel, the four feet contact the ground and the four bottom wheels leave the ground. The inventor of the present invention found that by respectively providing a foot and a bottom wheel at the four corners of the bottom of the clothing treatment device, and the foot or the bottom wheel is set to be height-adjustable, although it is convenient for the movement of the clothing treatment device, the stability of the clothing care device during the movement process is poor, and it is prone to tipping in extreme cases. Specifically, for clothing treatment devices such as clothing care machines and washing and drying mother and son machines stacked up and down, due to the overall height being relatively high, the center of the clothing treatment device is close to the middle and upper part of the machine body. When a person pushes the clothing treatment device to move, the thrust is applied to the middle of the clothing treatment device, and the bottom wheels of the clothing treatment device are subject to the frictional force in the direction opposite to the thrust direction of the ground. The thrust and the frictional force form a torque on the clothing treatment device, making the clothing treatment device tend to tip. In particular, when the bottom wheel rolls into the gap between the floor tiles on the ground, the resistance received by the bottom wheel increases, and the risk of the clothing treatment device tipping increases.

[0005] Therefore, a new technical solution is needed in the art to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the above technical problems, that is, to solve the problem of poor stability of existing clothing treatment devices during movement.

[0007] The present invention provides a clothing treatment device, which includes a box body. At each of two front corner positions at the bottom of the box body, a bottom wheel is provided respectively, and at each of two rear corner positions at the bottom of the box body, a bottom foot is provided respectively; at a position near the rear side at the bottom of the box body, a lifting wheel is further provided. A transmission mechanism is provided at the bottom of the box body. The first end of the transmission mechanism is close to the front part of the box body, and the second end of the transmission mechanism is connected to the lifting wheel, so as to manually drive the transmission mechanism to thereby realize the raising / lowering of the lifting wheel; in the placement state, the bottom wheels and the bottom feet jointly support the ground, so that the box body is in a vertical state; in the walking state, the lifting wheel descends and jointly supports the ground with the bottom wheels, and the bottom feet leave the ground, so that the box body is in a forward-tilted state.

[0008] In a preferred technical solution of the above clothing treatment device, the transmission mechanism includes a transmission rod, a moving member and a force amplification mechanism. The front end of the transmission rod is horizontally slidably connected to the bottom of the box body and the two are rotatably connected at the connection part around a horizontal axis perpendicular to the front-rear direction. The rear end of the transmission rod is slidably connected to the bottom of the box body in an inclined downward direction from front to back and the two are rotatably connected at the connection part around a horizontal axis perpendicular to the front-rear direction. The lifting wheel is rotatably connected to the rear end of the transmission rod; the moving member can only move in the front-rear direction. The rear end of the moving member abuts against the front end of the transmission rod. The force amplification mechanism is in transmission connection with the moving member, so that: when manually operating the force amplification mechanism to make the moving member move backward, the moving member pushes the transmission rod to move backward, and the rear end of the transmission rod moves backward and downward obliquely to make the lifting wheel descend to a state of jointly supporting the ground with the bottom wheels; when manually operating the force amplification mechanism to make the moving member move forward, the lifting wheel can be acted on by the ground force to move forward and upward obliquely to a state where the bottom wheels and the bottom feet jointly support the ground.

[0009] In the preferred technical solution of the above-mentioned clothing treatment device, the transmission mechanism includes a transmission rod, a moving member, and a force amplification mechanism. The front end of the transmission rod is horizontally slidably connected to the bottom of the box body, and the two are rotatably connected at the connection around a horizontal axis perpendicular to the front-rear direction. The rear end of the transmission rod is slidably connected to the bottom of the box body in an inclined downward direction from front to back, and the two are rotatably connected at the connection around a horizontal axis perpendicular to the front-rear direction. The lifting wheel is rotatably connected to the rear end of the transmission rod; the moving member can only move in the front-rear direction. The rear end of the moving member is rotatably connected to the front end of the transmission rod at the connection around a horizontal axis perpendicular to the front-rear direction. The force amplification mechanism is in transmission connection with the moving member, so that: when manually operating the force amplification mechanism to move the moving member backward, the moving member pushes the transmission rod backward, and the rear end of the transmission rod moves backward and downward obliquely, causing the lifting wheel to descend to a state where it jointly supports the ground with the bottom wheel; when manually operating the force amplification mechanism to move the moving member forward, the moving member pulls the transmission rod forward, and the rear end of the transmission rod moves forward and upward obliquely, causing the lifting wheel to rise to a state where the bottom wheel and the bottom feet jointly support the ground.

[0010] In the preferred technical solution of the above-mentioned clothing treatment device, a first bracket is fixed at the position of the bottom of the box body close to the moving member. A threaded hole extending in the front-rear direction is provided on the first bracket. The moving member includes a screw rod section, and the screw rod section penetrates into the threaded hole, so that when the force amplification mechanism drives the moving member to rotate around its axis, the moving member moves along its axis direction.

[0011] In the preferred technical solution of the above-mentioned clothing treatment device, the moving member further includes a gear section connected to the front end of the screw rod section. The gear section is coaxial with the screw rod section and rotates synchronously with the screw rod section. Each tooth on the gear section extends along the axial direction of the gear section. The force amplification mechanism includes a vertical screw rod and a rocker. The upper end of the vertical screw rod is rotatably connected to the bottom of the box body through a rotating shaft. The thread on the vertical screw rod cooperates with the teeth on the gear section. The first end of the rocker is connected to the lower end of the vertical screw rod, so that when manually driving the rocker to rotate, the vertical screw rod can be driven to rotate. The vertical screw rod rotates to drive the moving member to rotate. Under the cooperation of the screw rod section and the threaded hole, the moving member moves along its axis while rotating, thereby realizing the rising / falling of the lifting wheel.

[0012] In the preferred technical solution of the above-mentioned clothing processing equipment, the first end of the rocker is rotatably connected to the lower end of the vertical screw, and the rocker and the vertical screw are configured with a locking mechanism; when the locking mechanism locks the first end of the rocker and the vertical screw, the vertical screw can rotate synchronously with the rocker in the same direction when the rocker rotates along a preset direction; when the locking mechanism releases the lock of the first end of the rocker and the vertical screw, the rocker can rotate freely relative to the vertical screw.

[0013] In the preferred technical solution of the above-mentioned clothing processing equipment, the locking mechanism includes an annular member fixedly connected to the lower end of the vertical screw and coaxial with the vertical screw, and a plurality of tooth structures are distributed circumferentially on the annular member, and a groove structure is formed between two adjacent tooth structures. The locking mechanism also includes a clamping member arranged on the rocker, and at least a portion of the clamping member moves into / out of the groove structure to achieve locking / unlocking of the locking mechanism.

[0014] In a preferred technical solution of the above-mentioned clothing processing device, the clamping member includes a vertical rotating shaft pivotally connected to the rocking arm and a first extension rod and a second extension rod extending from both sides of the vertical rotating shaft toward the direction close to the annular member, the first extension rod and the second extension rod are symmetrical about the plane where the axis of the vertical screw and the axis of the vertical rotating shaft are located, and the first extension rod and the second extension rod can be selectively inserted into the groove structure by rotating the vertical rotating shaft; when the end of the first extension rod away from the vertical rotating shaft is inserted into the groove structure, the vertical screw rotates synchronously with the rocking arm in the same direction when the rocking arm rotates in the first direction, and the end of the first extension rod away from the vertical rotating shaft moves out of the groove structure when the rocking arm rotates in the second direction; when the end of the second extension rod away from the vertical rotating shaft is inserted into the groove structure, the vertical screw rotates synchronously with the rocking arm in the same direction when the rocking arm rotates in the second direction, and the end of the second extension rod away from the vertical rotating shaft moves out of the groove structure when the rocking arm rotates in the first direction.

[0015] In a preferred technical solution of the above-mentioned clothes processing device, a shifting rod is provided on a side of the vertical rotating shaft away from the vertical screw rod, so that the vertical rotating shaft can be rotated by manually shifting the shifting rod.

[0016] In a preferred technical solution of the above-mentioned clothes processing device, a second bracket is fixed to the bottom of the box body near the lifting wheel, and two opposite and parallel inclined slide grooves are formed on the second bracket. The inclined slide grooves extend obliquely downward from the front to the rear, and the axle of the lifting wheel is slidably and rotatably connected to the two inclined slide grooves, and the rear end of the transmission rod is rotatably connected to the axle of the lifting wheel.

[0017] In the case of adopting the above technical solution, the laundry treatment device includes a cabinet. A bottom wheel is respectively arranged at each of the two front corner positions at the bottom of the cabinet, and a bottom foot is respectively arranged at each of the two rear corner positions at the bottom of the cabinet; a lifting wheel is further arranged at a position near the rear side at the bottom of the cabinet, and a transmission mechanism is arranged at the bottom of the cabinet. The first end of the transmission mechanism is close to the front part of the cabinet, and the second end of the transmission mechanism is connected to the lifting wheel, so as to manually drive the transmission mechanism to realize the raising / lowering of the lifting wheel; in the placement state, the bottom wheels and the bottom feet jointly support the ground, so that the cabinet is in a vertical state; in the moving state, the lifting wheel descends and jointly supports the ground with the bottom wheels, and the bottom feet leave the ground, so that the cabinet is in a forward-tilted state.

[0018] Through such a setting, when moving the laundry treatment device, the lifting wheel descends and jointly supports the ground with the bottom wheels, so that the cabinet is in a forward-tilted state. A person stands in front of the laundry treatment device and pushes the laundry treatment device to move. The thrust of the person and the friction force form a torque on the laundry treatment device that causes the laundry treatment device to have a tendency to tip backward. Since the cabinet is in a forward-tilted state, the gravity of the cabinet forms a torque on the laundry treatment device that causes the laundry treatment device to have a tendency to tip forward. The two reverse torques act together, weakening the tipping tendency of the laundry treatment device, reducing the risk of the laundry treatment device tipping in extreme cases, and improving the stability of the laundry treatment device during the moving process.

[0019] Preferably, the transmission mechanism includes a transmission rod, a moving member and a force amplification mechanism. The front end of the transmission rod is horizontally slidably connected to the bottom of the cabinet and the two are rotatably connected at the connection part around a horizontal axis perpendicular to the front-back direction. The rear end of the transmission rod is inclined downward and slidably connected to the bottom of the cabinet along the front-to-back direction and the two are rotatably connected at the connection part around a horizontal axis perpendicular to the front-back direction. The lifting wheel is rotatably connected to the rear end of the transmission rod; the moving member can only move in the front-back direction, the rear end of the moving member abuts against the front end of the transmission rod, and the force amplification mechanism is in transmission connection with the moving member, so that: when manually operating the force amplification mechanism to make the moving member move backward, the moving member pushes the transmission rod to move backward, and the rear end of the transmission rod moves backward and obliquely downward to make the lifting wheel descend to a state of jointly supporting the ground with the bottom wheels; when manually operating the force amplification mechanism to make the moving member move forward, the lifting wheel can be acted on by the ground and move forward and obliquely upward to a state where the bottom wheels and the bottom feet jointly support the ground.

[0020] Through such a setting, the structure of the transmission mechanism is simple and occupies less space. Only by borrowing the limited space between the bottom of the laundry treatment device and the ground can the layout of the transmission mechanism be realized, reducing the modification to the cabinet of the laundry treatment device. In addition, when manually operating the transmission mechanism to adjust the height of the lifting wheel, the operator can more labor-savingly realize the adjustment of the height of the lifting wheel, improving the convenience of operation.

[0021] Preferably, a first bracket is fixed at a position on the bottom of the box body close to the moving member. A threaded hole extending in the front-rear direction is provided on the first bracket. The moving member includes a screw rod section which penetrates into the threaded hole so that when the force amplification mechanism drives the moving member to rotate about its axis, the moving member moves along its axis direction.

[0022] With such a setting, the movement of the moving member in the front-rear direction can be realized by rotating the moving member, which is convenient for the layout of the force amplification mechanism.

[0023] Preferably, the moving member further includes a gear section connected to the front end of the screw rod section. The gear section is coaxial with the screw rod section and rotates synchronously with the screw rod section. Each tooth on the gear section extends along the axial direction of the gear section. The force amplification mechanism includes a vertical screw rod and a rocker. The upper end of the vertical screw rod is rotatably connected to the bottom of the box body through a rotating shaft. The thread on the vertical screw rod cooperates with the teeth on the gear section. The first end of the rocker is connected to the lower end of the vertical screw rod so that when the rocker is manually driven to rotate, the vertical screw rod can be driven to rotate. The vertical screw rod rotates to drive the moving member to rotate. Under the cooperation of the screw rod section and the threaded hole, the moving member moves along its axis while rotating, thereby realizing the rising / falling of the lifting wheel.

[0024] With such a setting, the rocker can be rotated in the horizontal plane to cleverly realize the front-rear movement of the moving member, and then drive the lifting wheel to rise / fall through the transmission rod. In addition, the rocker is hidden at a position in front and below the bottom of the box body, which is not only convenient for manual operation, but also avoids affecting the setting area of the door body on the box body, and also ensures the overall beauty of the clothing treatment device.

[0025] Preferably, the first end of the rocker is rotatably connected to the lower end of the vertical screw rod, and the rocker and the vertical screw rod are provided with a locking mechanism; when the locking mechanism locks the first end of the rocker and the vertical screw rod, the vertical screw rod can rotate in the same direction as the rocker synchronously when the rocker rotates in a preset direction; when the locking mechanism releases the locking of the first end of the rocker and the vertical screw rod, the rocker can rotate freely relative to the vertical screw rod.

[0026] With such a setting, it is not necessary for the rocker to rotate a full circle to drive the vertical screw rod to rotate multiple circles in a preset direction, so that the moving member moves a preset distance in the front-rear direction, and then the lifting wheel rises / falls a preset height, further improving the convenience of operation.

Detailed implementation manners

[0035] First of all, those skilled in the art should understand that the following described implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0036] It should be noted that in the description of the invention, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0037] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the term "connection" 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 a direct connection or an indirect connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0038] Based on the problem that the existing clothing treatment equipment mentioned in the background technology has poor stability during movement, the present invention provides a clothing treatment equipment. The clothing treatment equipment includes a box body. At two front corner positions of the bottom of the box body, a bottom wheel is respectively arranged, and at two rear corner positions of the bottom of the box body, a bottom foot is respectively arranged; at a position near the rear side of the bottom of the box body, a lifting wheel is also arranged, and a transmission mechanism is arranged at the bottom of the box body. The first end of the transmission mechanism is close to the front part of the box body, and the second end of the transmission mechanism is connected to the lifting wheel, so as to manually drive the transmission mechanism to realize the raising / lowering of the lifting wheel; in the placement state, the bottom wheels and the bottom feet jointly support the ground, so that the box body is in a vertical state; in the walking state, the lifting wheel descends and jointly supports the ground with the bottom wheels, and the bottom feet leave the ground, so that the box body is in a forward-tilted state.

[0039] Through such a setting, when moving the clothing treatment equipment, the lifting wheel descends and jointly supports the ground with the bottom wheels, so that the box body is in a forward-tilted state. A person stands in front of the clothing treatment equipment and pushes the clothing treatment equipment to move. The pushing force of the person and the frictional force form a torque on the clothing treatment equipment that causes the clothing treatment equipment to have a tendency to fall backward. Since the box body is in a forward-tilted state, the gravity of the box body forms a torque on the clothing treatment equipment that causes the clothing treatment equipment to have a tendency to fall forward. The two reverse torques act together, weakening the tendency of the clothing treatment equipment to fall, reducing the risk of the clothing treatment equipment falling in extreme cases, and improving the stability of the clothing treatment equipment during movement.

[0040] The following refers to Figures 1 to 5 and combines with a clothing care machine to introduce the clothing treatment equipment of the present invention in detail. Among them, Figure 1 is a schematic structural diagram of a clothing care machine according to an embodiment of the present invention; Figure 2 is a schematic structural diagram of an assembly of a transmission mechanism and a lifting wheel of a clothing care machine according to an embodiment of the present invention; Figure 3 is Figure 2 an enlarged view of a partial A; Figure 4 is Figure 2 an enlarged view of a partial B; Figure 5 is a schematic diagram of a force amplification structure in the transmission mechanism of a clothing care machine according to an embodiment of the present invention (in the state of removing the cover plate of the rocker).

[0041] As Figures 1 to 5 shown, the clothing care machine includes a box body 1. A door body 11 is arranged at the front part of the box body 1. At two front corner positions of the bottom of the box body 1, a bottom wheel 21 is respectively arranged, and at two rear corner positions of the bottom of the box body 1, a bottom foot 22 is respectively arranged; at a position near the rear side of the bottom of the box body 1, a lifting wheel 3 is also arranged, and a transmission mechanism is arranged at the bottom of the box body 1. The first end of the transmission mechanism is close to the front part of the box body 1, and the second end of the transmission mechanism is connected to the lifting wheel 3. The transmission mechanism includes a transmission rod 4, a moving part 5, and a force amplification mechanism 6.

[0042] At a position near the front side of the bottom of the box body 1, a first bracket 41 is provided, and at a position near the rear side of the bottom of the box body 1, a second bracket 42 is provided. The first bracket 41 includes a first horizontal plate 411 and two first vertical plates 412. Both the first horizontal plate 411 and the first vertical plates 412 are vertical plates. The first horizontal plate 411 extends in the left - right direction, the two first vertical plates 412 extend in the front - rear direction and are arranged opposite to each other. The upper edges of the first horizontal plate 411 and the first vertical plates 412 are fixedly connected to the bottom of the box body 1, and the front ends of the two first vertical plates 412 are fixedly connected to the first horizontal plate 411. A threaded hole 4111 is provided on the first horizontal plate 411, and horizontal chutes 4121 extending in the front - rear direction and opposite to each other are respectively provided on the two first vertical plates 412. The second bracket 42 includes two second vertical plates 421. The two second vertical plates 421 are vertical plates. The two second vertical plates 421 extend in the front - rear direction, the upper edges of the two second vertical plates 421 are fixedly connected to the bottom of the box body 1, and inclined chutes 4211 that are opposite to each other and parallel to each other are respectively provided on the two second vertical plates 421. The inclined chutes 4211 extend obliquely downward in the front - to - rear direction. The front end of the transmission rod 4 is slidably and rotatably connected to the horizontal chutes 4121 through the rotating shafts on the left and right sides. The rear end of the transmission rod 4 is rotatably connected to the rotating shaft of the lifting wheel 3, and the rotating shaft of the lifting wheel 3 is slidably and rotatably connected to the inclined chutes 4211.

[0043] The moving part 5 includes a screw rod section 51 and a gear section 52 fixedly connected to the front end of the screw rod section 51. The screw rod section 51 penetrates into the threaded hole 4111. The screw rod section 51 has a right - hand thread. The thread of the screw rod section 51 is matched with the thread of the threaded hole 4111 so that the screw rod section 51 can move along its axis when it rotates. The rear end of the screw rod section 51 abuts against the front end of the transmission rod 4. Each tooth of the gear section 52 extends along the axial direction of the gear section 52.

[0044] The force amplification mechanism 6 includes a vertical screw 61 and a rocker 62. The upper end of the vertical screw 61 is rotatably connected to the bottom of the housing 1 via a rotating shaft. The vertical screw 61 has a right-handed thread. The thread on the vertical screw 61 cooperates with the teeth on the gear segment 52 so that the gear segment 52 is driven to rotate when the vertical screw 61 rotates. The first end of the rocker 62 is rotatably connected to the lower end of the vertical screw 61. The rocker 62 includes a base plate 621 and a cover plate 622 that interlock with each other. The vertical screw 61 and the rocker 62 are equipped with a locking mechanism. The locking mechanism includes an annular member 631 that is fixedly connected to the lower end of the vertical screw 61 and is coaxial with the vertical screw 61. A plurality of tooth structures 6311 are circumferentially distributed on the outer annular surface of the annular member 631, and a groove structure 6312 is formed between two adjacent tooth structures 6311. The locking mechanism also includes a clip 632 disposed on the rocker 62. The clip 632 includes a vertical shaft 6321 pivotally connected to the rocker 62, and a first extension rod 6322 and a second extension rod 6323 extending from either side of the vertical shaft 6321 toward the annular member 631. The first and second extension rods 6322 and 6323 are arc-shaped and symmetrical about the plane containing the axis of the vertical screw 61 and the axis of the vertical shaft 6321. The first and second extension rods 6322 and 6323 can be selectively inserted into the corresponding slot structure 6312 by rotating the vertical shaft 6321. A lever 6324 is connected to the side of the vertical shaft 6321 away from the vertical screw 61 via a connecting rod, so that the vertical shaft 6321 can be rotated by manually toggling the lever 6324. The cover plate 622 is formed with a through hole 6221 for the shifting rod 6324 to pass through.

[0045] When it is necessary to move the laundry care machine, manually turn the lever 6324 clockwise (from a top view angle) by a certain angle. One end of the second extension rod 6323 away from the vertical rotating shaft 6321 is inserted into a groove structure 6312 at a corresponding position, and the locking mechanism locks the rocker 62 and the vertical screw 61. Manually drive the rocker 62 to rotate clockwise (from a top view angle) by a certain angle, and the vertical screw 61 rotates synchronously and in the same direction as the rocker 62 by the same angle. Then manually drive the rocker 62 to rotate counterclockwise (from a top view angle) by a corresponding angle to reset the rocker 62. During this process, one end of the second extension rod 6323 away from the vertical rotating shaft 6321 slides out of the groove structure 6312, and the locking mechanism releases the locking of the rocker 62 and the vertical screw 61. After that, manually turn the lever 6324 clockwise (from a top view angle) by a certain angle. One end of the second extension rod 6323 away from the vertical rotating shaft 6321 is inserted into a groove structure 6312 at a corresponding position, and the locking mechanism locks the rocker 62 and the vertical screw 61 again. Manually drive the rocker 62 to rotate clockwise (from a top view angle) by a certain angle, and the vertical screw 61 rotates synchronously and in the same direction as the rocker 62 by the same angle. Then manually drive the rocker 62 to rotate counterclockwise (from a top view angle) by a corresponding angle to reset the rocker 62. Repeat this cycle to achieve multiple clockwise (from a top view angle) rotations of the vertical screw 61. During the clockwise (from a top view angle) rotation of the vertical screw 61, the vertical screw 61 drives the gear section 52 to rotate clockwise (from a front view angle), and the screw section 51 rotates synchronously with the gear section 52. Due to the cooperation between the screw section 51 and the threaded hole 4111, the screw section 51 moves forward from back to front synchronously during the clockwise (from a front view angle) rotation. Since each tooth on the gear section 52 extends along its axial direction, the gear section 52 moves forward from back to front with the screw section 51, and the gear section 52 has sufficient length to ensure that the teeth on it always engage with the threads of the vertical screw 61. During the forward movement of the screw section 51 from back to front, the rear end of the screw section 51 pushes the transmission rod 4. The front end of the transmission rod 4 slides forward from back to front and rotates around the rotating shafts on both sides. The rear end of the transmission rod 4 slides obliquely downward along the inclined sliding groove 4211 and rotates relative to the rotating shaft of the lifting wheel 3, and the rotating shaft of the lifting wheel 3 slides obliquely downward along the inclined sliding groove 4211. When the lifting wheel 3 supports the ground and makes the two feet 22 leave the ground, stop rotating the rocker 62. At this time, the bottom wheel 21 and the lifting wheel 3 jointly support the ground, and the box body 1 is in a forward-tilted state. A person stands in front of the laundry care machine and pushes the laundry care machine to move.

[0046] The thrust of a person and the frictional force form a torque on the clothing care machine that causes the clothing care machine to tend to tip backward. Since the box body 1 is in a forward-tilted state, the gravity of the box body 1 forms a torque on the clothing care machine that causes the clothing care machine to tend to tip forward. The combined action of these two reverse torques weakens the tipping tendency of the clothing care machine, reduces the risk of the clothing care machine tipping over in extreme cases, and improves the stability of the clothing care machine during the moving process.

[0047] When the clothing care machine moves into place, manually turn the lever 6324 counterclockwise (from a top-down perspective) by a certain angle. One end of the first extension rod 6322 away from the vertical rotating shaft 6321 is inserted into a groove structure 6312 at the corresponding position, and the locking mechanism locks the rocker 62 and the vertical screw 61. Manually drive the rocker 62 to rotate counterclockwise (from a top-down perspective) by a certain angle, and the vertical screw 61 rotates synchronously and in the same direction as the rocker 62 by the same angle. Then manually drive the rocker 62 to rotate clockwise (from a top-down perspective) by the corresponding angle to reset the rocker 62. During this process, one end of the first extension rod 6322 away from the vertical rotating shaft 6321 slides out of the groove structure 6312, and the locking mechanism releases the locking of the rocker 62 and the vertical screw 61. After that, manually turn the lever 6324 counterclockwise (from a top-down perspective) by a certain angle, and one end of the first extension rod 6322 away from the vertical rotating shaft 6321 is inserted into a groove structure 6312 at the corresponding position, and the locking mechanism locks the rocker 62 and the vertical screw 61 again. Manually drive the rocker 62 to rotate counterclockwise (from a top-down perspective) by a certain angle, and the vertical screw 61 rotates synchronously and in the same direction as the rocker 62 by the same angle. Then manually drive the rocker 62 to rotate clockwise (from a top-down perspective) by the corresponding angle to reset the rocker 62. Repeat this cycle to achieve multiple counterclockwise (from a top-down perspective) rotations of the vertical screw 61. During the counterclockwise (from a top-down perspective) rotation of the vertical screw 61, the vertical screw 61 drives the gear section 52 to rotate counterclockwise (from a front view perspective), and the screw section 51 rotates synchronously with the gear section 52. Due to the cooperation between the screw section 51 and the threaded hole 4111, the screw section 51 moves forward from back to front synchronously during the counterclockwise (from a front view perspective) rotation. Since each tooth on the gear section 52 extends along its axial direction, the gear section 52 moves forward from back to front with the screw section 51, and the gear section 52 has sufficient length to ensure that the teeth on it always engage with the threads of the vertical screw 61. During the forward movement of the screw section 51 from back to front, the thrust of the rear end of the screw section 51 on the transmission rod 4 decreases, and the force of the transmission rod 4 on the axle of the lifting wheel 3 decreases. At this time, the force of the ground on the lifting wheel 3 is relatively large, and the rotating shaft of the lifting wheel 3 slides obliquely upward along the inclined chute 4211, thereby causing the rear end of the transmission rod 4 to slide obliquely upward along the inclined chute 4211 and rotate relative to the rotating shaft of the lifting wheel 3. The front end of the transmission rod 4 slides forward from back to front and rotates around the rotating shafts on both sides. When the two feet 22 contact the ground and play a supporting role, stop rotating the rocker 62. At this time, the bottom wheels 21 and the feet 22 jointly support the ground, and the box body 1 is in a vertical state.

[0048] It should be noted that a lever 6324 is connected to the side of the vertical rotating shaft 6321 away from the vertical screw 61 through a connecting rod. This is only a relatively preferred setting method, and adjustments can be made in actual applications. For example, the lever 6324 can be not provided, and the vertical rotating shaft 6321 can be directly driven manually to rotate. In addition, the first extension rod 6322 and the second extension rod 6323 are arc-shaped. This is only a specific setting method, and adjustments can be made in actual applications. For example, both the first extension rod 6322 and the second extension rod 6323 are straight rods. In addition, the screw section 51 has a right-handed thread. This is only a specific setting method, and adjustments can be made in actual applications. For example, the screw section 51 has a left-handed thread, and accordingly, the thread rotation direction of the threaded hole 4111 needs to be adjusted. When operating specifically, the rotation direction of the rocker 62 is adjusted according to the situation. The vertical screw 61 has a right-handed thread. This is only a specific setting method, and adjustments can be made in actual applications. For example, the vertical screw 61 has a left-handed thread, and accordingly, the rotation direction of the rocker 62 is adjusted according to the situation when operating specifically.

[0049] It should also be noted that the rocker 62 includes a bottom plate 621 and a cover plate 622 that are buckled with each other. This is only a specific setting method, and adjustments can be made in actual applications. For example, the rocker can be set as a single rod. In addition, horizontal chutes 4121 extending in the front-rear direction and opposite to each other are respectively provided on the two first vertical plates 412. The front end of the transmission rod 4 is slidably and rotatably connected to the horizontal chutes 4121 through the left and right side rotating shafts. This is only a specific setting method, and adjustments can be made in actual applications. For example, relative extending rotating shafts are respectively provided on the two first vertical plates 412, and horizontal chutes extending in the front-rear direction and opposite to each other are respectively provided on the left and right sides of the front part of the transmission rod 4. The horizontal chutes on the left and right sides of the front part of the transmission rod 4 are slidably and rotatably connected to the rotating shafts on the two first vertical plates 412. In addition, the rear end of the transmission rod 4 can be slidably and rotatably connected to the inclined chute 4211 through the left and right side rotating shafts. The rotating shaft of the lifting wheel 3 is rotatably connected to the rear end of the transmission rod 4.

[0050] On the basis of the above embodiments, preferably, the lever 6324 is rotatably connected to the first end of the spring, and the second end of the spring is rotatably connected to the fixed column on the bottom plate 621. The fixed column is located on the side of the lever 6324 away from the vertical rotating shaft 6321. The fixed column, the vertical rotating shaft 6321, and the rotating shaft of the vertical screw 61 are located in the same vertical plane, and the spring is always in a compressed state.

[0051] During the process of lowering the lifting wheel 3, after manually turning the lever 6324 clockwise (from a top-down perspective), the lever 6324 rotates a certain angle clockwise (from a top-down perspective) around the vertical rotating shaft 6321 under the elastic force of the spring, causing the end of the second extension rod 6323 away from the vertical rotating shaft 6321 to insert into a groove structure 6312 at a corresponding position, and the locking mechanism locks the rocker 62 and the vertical screw 61. During the process of manually driving the rocker 62 to rotate counterclockwise (from a top-down perspective) by a corresponding angle to reset the rocker 62, after the end of the second extension rod 6323 away from the vertical rotating shaft 6321 slides out of the groove structure 6312, under the elastic force of the spring, the end of the second extension rod 6323 away from the vertical rotating shaft 6321 will further insert into an adjacent groove structure 6312 as the vertical rotating shaft 6321 rotates, and finally be located in a groove structure 6312. After that, there is no need to manually turn the lever 6324 anymore, and the rocker 62 can be directly driven to rotate clockwise (from a top-down perspective).

[0052] During the process of raising the lifting wheel 3, after manually turning the lever 6324 counterclockwise (from a top-down perspective), the lever 6324 rotates a certain angle counterclockwise (from a top-down perspective) around the vertical rotating shaft 6321 under the elastic force of the spring, causing the end of the first extension rod 6322 away from the vertical rotating shaft 6321 to insert into a groove structure 6312 at a corresponding position, and the locking mechanism locks the rocker 62 and the vertical screw 61. During the process of manually driving the rocker 62 to rotate clockwise (from a top-down perspective) by a corresponding angle to reset the rocker 62, after the end of the first extension rod 6322 away from the vertical rotating shaft 6321 slides out of the groove structure 6312, under the elastic force of the spring, the end of the first extension rod 6322 away from the vertical rotating shaft 6321 will further insert into an adjacent groove structure 6312 as the vertical rotating shaft 6321 rotates, and finally be located in a groove structure 6312. After that, there is no need to manually turn the lever 6324 anymore, and the rocker 62 can be directly driven to rotate counterclockwise (from a top-down perspective).

[0053] With such a setting, there is no need to frequently operate manually to lock the rocker 62 and the vertical screw 61.

[0054] In another feasible embodiment, different from the above embodiment, the clamping member is set as a slide bar parallel to the rocker 62, and the slide bar can move one end into / out of a groove structure 6312 by sliding; when one end of the slide bar moves into the groove structure 6312, the rocker 62 and the vertical screw 61 are locked, and when one end of the slide bar moves out of the groove structure 6312, the rocker 62 and the vertical screw 61 are unlocked; before reversing the rotation of the rocker 62 to reset, it is necessary to manually move one end of the slide bar out of the groove structure 6312 to release the lock between the rocker 62 and the vertical screw 61.

[0055] In another feasible embodiment, different from the above embodiment, the gear section 52 is connected to the screw section 51 by a spline. That is to say, the gear section 52 and the screw section 51 can move relative to each other axially. Both ends of the gear section 52 are directly rotatably connected to the bottom of the box body 1 through optical axes, so that the gear section 52 does not move axially along with the screw section 51 when the vertical screw 61 drives the gear section 52 to rotate.

[0056] In another feasible embodiment, different from the above embodiment, the locking mechanism is not provided, and the first end of the rocker 62 is directly fixedly connected to the lower end of the vertical screw 61. In order to avoid the need for the rocker 62 to rotate multiple turns to achieve the lifting of the lifting wheel 3 at a specific height, the ratio of the diameter of the vertical screw 61 to the diameter of the gear section 52 can be set to a relatively large value (such as 3, 4, 5, etc.).

[0057] In another feasible embodiment, different from the above embodiment, the moving member 5 does not include the gear section 52, and the force amplification mechanism is provided as a handwheel fixedly connected to the front end of the screw section 51, and the screw section 51 is rotated by rotating the handwheel.

[0058] In another feasible embodiment, different from the above embodiment, the first bracket 41 does not include the first longitudinal plate 412, the second bracket 42 is not provided at the bottom of the box body 1, a groove extending in the front-rear direction is provided at the bottom of the box body 1, the horizontal sliding groove 4121 is provided at a position close to the front end of the side wall extending in the front-rear direction of the groove, and the inclined sliding groove 4211 is provided at a position close to the rear end of the side wall extending in the front-rear direction of the groove.

[0059] In another feasible embodiment, which is different from the above embodiment, the above locking mechanism is not provided. A coaxial prism is fixedly connected to the lower end of the vertical screw rod 61, and a groove or through hole adapted to the shape and size of the prism is provided at the first end of the rocker 62. In the non-use state, the rocker 62 and the vertical screw rod 61 are in a separated state. When it is necessary to raise or lower the lifting wheel 3, the groove or through hole at the first end of the rocker 62 is sleeved on the prism at the lower end of the vertical screw rod 61. After the rocker 62 drives the vertical screw rod 61 to rotate a certain angle, the groove or through hole at the first end is disengaged from the prism at the lower end of the vertical screw rod 61. Then, the groove or through hole at the first end of the rocker 62 is sleeved on the prism at the lower end of the vertical screw rod 61 in the previous orientation, and the rocker 62 is rotated to drive the vertical screw rod 61 to rotate. In another feasible embodiment, which is different from the above embodiment, the above locking mechanism is not provided. A coaxial clamping section is fixedly connected to the lower end of the vertical screw rod 61. The operator can use a wrench, pliers, etc. to clamp the clamping section to drive the vertical screw rod 61 to rotate. The clamping section at the lower end of the vertical screw rod 61 can also be replaced with a "one"-shaped or "cross"-shaped groove provided at the lower end of the vertical screw rod 61. After the operator cooperates a screwdriver of the corresponding type with the "one"-shaped or "cross"-shaped groove at the lower end of the vertical screw rod 61, the screwdriver is rotated to drive the vertical screw rod 61 to rotate.
