Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and specifically provides a clothing processing device. Background Technology

[0002] Currently, garment care machines, washing machines, and dryers have become common household appliances. Most garment care devices have feet at the four corners of their base for support. However, when using these devices, they are often moved from their storage location to a specific spot to connect water hoses or to retrieve clothes from the loading / unloading ports on the top. Moving these devices requires lifting them, and due to their weight, this presents a significant challenge.

[0003] To facilitate movement, the improved clothes handling equipment has added lifting wheels at the bottom. For example, a washing machine disclosed in patent document (CN115874412A) has a set of movable wheels at two corners on one side of the bottom of the washing machine, and feet at two feet on the other side of the bottom. A lifting wheel assembly is located between the two feet on the bottom of the washing machine. The lifting wheel assembly includes a lifting wheel bracket, a rotating shaft passing through the lifting bracket, and lifting wheels mounted on the rotating shaft. Two guide members are installed on both sides of the lifting wheel bracket at the bottom of the washing machine. Guide grooves are formed on the sidewall of the guide members facing the lifting wheel bracket. The guide grooves extend downwards at an angle from the side of the guide members facing the washing machine towards the side opposite to the washing machine. The two ends of the rotating shaft pass through the lifting wheel bracket... A lowering wheel bracket is slidably connected to a guide groove. A slider passes through the rotating shaft. A drive lever is connected to the bottom of the washing machine via an elastic element. A movable support frame is pivotally connected to the drive lever, with the lowest point of the movable support frame lower than the lowest point of the drive lever. The first end of the drive lever extends downward from the side of the drive lever facing the washing machine toward the slider to form a first inclined surface. The first end of the slider extends downward from the side of the slider facing the washing machine toward the drive lever to form a second inclined surface. The lower end of the first inclined surface slides into the second inclined surface. The upper region of the second inclined surface has a locking groove that matches the shape of the lower end of the first inclined surface to lock the position of the slider. A limit plate is provided at the bottom of the washing machine. The limit plate extends from the end face near the drive lever toward the slider to limit the movement of the drive lever and the slider in the direction of the rotating shaft. When the washing machine needs to be moved, the second end of the drive lever rotates vertically downwards (towards the ground), causing the movable support frame to rest on the ground and providing support for the rotation of the drive lever. The lower end of the first inclined plane slides along the upper area of ​​the second inclined plane, pushing the slider away from the drive lever and causing the rotating shaft to move downwards along the guide groove. This gradually increases the distance between the lifting wheel and the bottom of the washing machine, allowing the lifting wheel to rest on the ground while the bottom feet are suspended in the air. At this point, the lower end is engaged in the locking groove, and then the lifting wheel rotates to move the washing machine, making the movement of the washing machine more convenient, quick, and labor-saving. When the washing machine is moved to the predetermined position, the second end of the drive lever rotates vertically upwards (towards the ground), causing the lower end of the first inclined plane to disengage from the locking groove and slide along the lower area of ​​the second inclined plane. This pushes the slider towards the drive lever, causing the rotating shaft to move upwards along the guide groove. This gradually decreases the distance between the lifting wheel and the bottom of the washing machine, allowing the lifting wheel to suspend in the air, and then the bottom feet touch the ground to support the washing machine and prevent it from moving during operation.

[0004] Although the aforementioned washing machine incorporates a lifting wheel assembly, this assembly, through the cooperation of a drive lever, slider, and guide, allows for the lifting of the wheels to support the ground when the washing machine needs to be moved. The lifting wheels and the moving wheels work together to support the ground, facilitating movement. However, due to the limited distance between the bottom of the washing machine and the ground, the length of the drive lever in the mechanism that drives the lifting wheel assembly is restricted. A significant downward force is required at the second end of the drive lever to rotate it vertically downwards, causing the lower end of the first inclined surface to engage in the locking groove, thus supporting the lifting wheel on the ground. In other words, the height adjustment of the lifting wheel assembly in the aforementioned washing machine is not effortless.

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

[0006] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that the height adjustment of the lifting wheel assembly of the existing washing machine is not labor-saving enough.

[0007] This invention provides a garment processing device, comprising a housing, with a base wheel at each of the two rear corners of the bottom of the housing and a foot at each of the two front corners of the bottom of the housing. A lifting wheel assembly is also provided near the front of the bottom of the housing. The lifting wheel assembly includes a wheel frame, rollers mounted to the wheel frame, a vertical shaft with its lower end connected to the wheel frame, and a swing arm rotatably connected to the vertical shaft around its axis. A locking mechanism is provided between the swing arm and the vertical shaft, selectively locking the swing arm to the vertical shaft so that, in the locked state, the swing arm drives the vertical shaft to rotate synchronously. The vertical shaft is threaded into the bottom of the housing so that when the vertical shaft rotates around its axis, it drives the rollers to move vertically.

[0008] In the preferred embodiment of the above-mentioned garment processing equipment, the locking mechanism includes a plurality of first locking structures distributed circumferentially along the vertical axis, and the swing arm is provided with a locking member movably connected thereto. The locking member has a second locking structure formed thereon. The swing arm can be locked to any of the first locking structures through the second locking structure, so as to lock the swing arm to the vertical axis.

[0009] In the preferred technical solution of the above-mentioned clothing processing equipment, a ring-shaped component is fixedly connected or integrally formed on the vertical shaft, and multiple tooth structures are distributed circumferentially on the ring-shaped component, with a groove structure formed between two adjacent tooth structures; the tooth structure constitutes the first snap-fit ​​structure, and the second snap-fit ​​structure is a snap groove adapted to the tooth structure, or the groove structure constitutes the first snap-fit ​​structure, and the second snap-fit ​​structure is a snap block adapted to the groove structure.

[0010] In the preferred embodiment of the above-mentioned garment processing equipment, the groove structure constitutes the first snap-fit ​​structure, the snap-fit ​​component includes a first snap-fit ​​component and a second snap-fit ​​component, the first end of the first snap-fit ​​component and the first end of the second snap-fit ​​component are both pivotally connected to the swing arm about a pivot parallel to the vertical axis, the second snap-fit ​​structure includes a first locking block formed by the second end of the first snap-fit ​​component and a second locking block formed by the second end of the second snap-fit ​​component; when the first snap-fit ​​component is pivoted to the state where the first locking block is inserted into the groove structure and the second snap-fit ​​component is pivoted to the state where the second locking block is not inserted into the groove structure, the swing arm rotates around the vertical axis along the first direction. When the rocker arm rotates, it locks with the vertical axis and drives the vertical axis to rotate synchronously in the first direction. When the rocker arm rotates around the vertical axis in the second direction, it unlocks with the vertical axis and cannot drive the vertical axis to rotate with the rocker arm. When the second locking member pivots to the state where the second locking block is inserted into the slot structure and the first locking member pivots to the state where the first locking block is not inserted into the slot structure, when the rocker arm rotates around the vertical axis in the second direction, it locks with the vertical axis and drives the vertical axis to rotate synchronously in the second direction. When the rocker arm rotates around the vertical axis in the first direction, it unlocks with the vertical axis and cannot drive the vertical axis to rotate with the rocker arm.

[0011] In the preferred embodiment of the above-mentioned garment processing equipment, the first end of the first snap-fit ​​member is pivotally connected to the swing rod around a first rotating shaft parallel to the vertical axis, and the first end of the second snap-fit ​​member is pivotally connected to the swing rod around a second rotating shaft parallel to the vertical axis.

[0012] In the preferred embodiment of the above-mentioned garment processing equipment, the locking mechanism further includes a first elastic mechanism, a second elastic mechanism, and a limiting mechanism; when the first latching member is not acted upon by the limiting mechanism, the first latching member pivots under the action of the first elastic mechanism to the position where the first latching block is inserted into the slot structure; when the second latching member is not acted upon by the limiting mechanism, the second latching member pivots under the action of the second elastic mechanism to the position where the second latching block is inserted into the slot structure; the limiting mechanism enables the first latching member to remain in the position where the first latching block is removed from the slot structure, and enables the second latching member to remain in the position where the second latching block is removed from the slot structure.

[0013] In the preferred embodiment of the above-mentioned garment processing equipment, the first elastic mechanism includes a first spring, the first end of the first spring is connected to the side of the first latching member away from the second latching member, the second end of the first spring is connected to the swing rod, and the first spring is always in a compressed state; and / or the second elastic mechanism includes a second spring, the first end of the second spring is connected to the side of the second latching member away from the first latching member, the second end of the second spring is connected to the swing rod, and the second spring is always in a compressed state.

[0014] In the preferred embodiment of the above-mentioned garment processing equipment, the limiting mechanism includes a cam disposed between the first latching member and the second latching member, the cam being pivotally connected to the swing arm, and the rotation axis of the cam being parallel to the vertical axis; when the cam rotates to the first position, the first latching member is held in the position where the first latching block moves out of the slot structure by the action of the first elastic mechanism and the support of the cam; when the cam rotates to the second position, the second latching member is held in the position where the second latching block moves out of the slot structure by the action of the second elastic mechanism and the support of the cam.

[0015] In the preferred embodiment of the above-mentioned garment processing equipment, the lower end of the vertical shaft is rotatably connected to the wheel frame, and the roller is a cylindrical roller.

[0016] In the preferred embodiment of the above-mentioned garment processing equipment, the lower end of the vertical shaft is fixedly connected to the wheel frame, and the roller is a spherical roller.

[0017] When the above technical solution is adopted, the garment processing equipment includes a box body, with a bottom wheel at each of the two rear corners of the bottom of the box body and a foot at each of the two front corners of the bottom of the box body. A lifting wheel assembly is also provided at the bottom of the box body near the front side. The lifting wheel assembly includes a wheel frame, rollers mounted to the wheel frame, a vertical shaft connected to the wheel frame at its lower end, and a swing arm rotatably connected to the vertical shaft around its axis. A locking mechanism is provided between the swing arm and the vertical shaft. The locking mechanism is used to selectively lock the swing arm and the vertical shaft so that the swing arm drives the vertical shaft to rotate synchronously in the locked state. The vertical shaft is threadedly engaged with the bottom of the box body so that when the vertical shaft rotates around its axis, it drives the rollers to move vertically.

[0018] With this setup, when the roller height needs adjustment, the swing arm is locked to the vertical shaft via a locking mechanism. Rotating the swing arm drives the vertical shaft to rotate synchronously. Because the vertical shaft is threaded into the bottom of the housing, its rotation around its axis causes the roller to move vertically, thus adjusting the roller height. Since the swing arm rotates around the vertical shaft's axis and is connected to it in a horizontal plane, and the horizontal space below the garment processing equipment is much larger than the vertical space, the swing arm can be a relatively long rod. Furthermore, the threaded connection between the vertical shaft and the bottom of the housing, allowing the vertical shaft to rotate around its axis and drive the roller vertically, works synergistically. This means that when manually driving the swing arm to rotate around the vertical shaft's axis, which in turn drives the vertical shaft to rotate synchronously, only a small force is needed to adjust the roller height, facilitating roller height adjustment. Because the locking mechanism can selectively lock the rocker arm and the vertical axis, during the adjustment of the roller height, the rocker arm and the vertical axis are first locked by the locking mechanism. The rocker arm rotates a certain angle around the axis of the vertical axis in a first direction. Then, the lock is released, and the rocker arm rotates a corresponding angle around the axis of the vertical axis in a second direction before resetting. This process is repeated, allowing the vertical axis to move vertically. This eliminates the need for the rocker arm to rotate a full circle around the axis of the vertical axis, simplifying the operation of driving the rocker arm's rotation.

[0019] Preferably, the locking mechanism includes a plurality of first locking structures distributed circumferentially along the vertical axis, and the rocker arm is provided with a locking member movably connected thereto. A second locking structure is formed on the locking member. The rocker arm can be locked with any of the first locking structures through the second locking structure to achieve locking of the rocker arm and the vertical axis.

[0020] This setup allows for convenient and quick locking and unlocking of the lever and vertical axis.

[0021] Preferably, a ring-shaped component is fixedly connected to or integrally formed on the vertical shaft. Multiple toothed structures are distributed circumferentially on the ring-shaped component, with a groove structure formed between adjacent toothed structures. The groove structure constitutes a first locking structure. The locking component includes a first locking component and a second locking component. The first end of both the first and second locking components is pivotally connected to the rocker arm about a pivot parallel to the vertical shaft. The second locking structure includes a first locking block formed by the second end of the first locking component and a second locking block formed by the second end of the second locking component. The first locking component pivots until the first locking block inserts into the groove structure and the second locking component pivots. When the second locking block is not inserted into the slot structure, the swing arm is locked to the vertical axis when rotating around the vertical axis in the first direction, thus driving the vertical axis to rotate synchronously in the first direction. When the swing arm rotates around the vertical axis in the second direction, it is unlocked from the vertical axis and cannot drive the vertical axis to rotate with the swing arm. When the second locking member is pivoted to the second locking block insertion slot structure and the first locking member is pivoted to the first locking block not inserted into the slot structure, the swing arm is locked to the vertical axis when rotating around the vertical axis in the second direction, thus driving the vertical axis to rotate synchronously in the second direction. When the swing arm rotates around the vertical axis in the first direction, it is unlocked from the vertical axis and cannot drive the vertical axis to rotate with the swing arm.

[0022] With this setup, the rocker arm can be unlocked by rotating it in the reset direction, eliminating the need for a separate unlocking operation and further facilitating the height adjustment of the rollers.

[0023] Preferably, the first end of the first latching member is pivotally connected to the swing arm about a first pivot parallel to the vertical axis, and the first end of the second latching member is pivotally connected to the swing arm about a second pivot parallel to the vertical axis; the locking mechanism further includes a first elastic mechanism, a second elastic mechanism, and a limiting mechanism; when the first latching member is not under the action of the limiting mechanism, the first latching member pivots to the position of the first latching block insertion slot structure under the action of the first elastic mechanism; when the second latching member is not under the action of the limiting mechanism, the second latching member pivots to the position of the second latching block insertion slot structure under the action of the second elastic mechanism; the limiting mechanism can keep the first latching member in the position where the first latching block moves out of the slot structure, and can keep the second latching member in the position where the second latching block moves out of the slot structure.

[0024] With this configuration, when the roller needs to rise or fall vertically, the limiting mechanism keeps the first or second locking member in the position where the first or second locking block is removed from the slot structure. Without the action of the limiting member, the second or first locking member can pivot to the position where the second or first locking block is inserted into the slot structure under the action of the second or first elastic mechanism. Thus, after the rocker arm rotates a certain angle in the reset direction and stops rotating, the second or first locking block automatically inserts into the slot structure. This allows the rocker arm to automatically lock with the vertical axis when the rocker arm rotates again in the direction of driving the vertical axis, reducing locking operations and further facilitating the height adjustment of the roller.

[0025] Preferably, the lower end of the vertical shaft is rotatably connected to the wheel frame, and the roller is a cylindrical roller.

[0026] With this setup, when the roller descends to the support surface, even if the roller's axis is not perpendicular to the direction of movement of the garment handling equipment, the roller can automatically adjust its direction during the movement of the garment handling equipment, making its axis perpendicular to the direction of movement, thus facilitating the roller's rolling on the ground. Furthermore, when the rotating lever drives the shaft to move vertically downwards to the support surface, it is not necessary for the roller to rotate with the vertical axis to a position where its axis is perpendicular to the direction of movement of the garment handling equipment, further simplifying the adjustment of the roller's height.

[0027] Preferably, the lower end of the vertical shaft is fixedly connected to the wheel frame, and the roller is a spherical roller.

[0028] With this setup, when the roller moves vertically downwards to the supporting ground by rotating the vertical shaft via the swing arm, there is no need to consider the rotation direction of the roller, making it easier to adjust the height of the roller. Attached Figure Description

[0039] First, those skilled in the art should understand that the embodiments described below are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0040] It should be noted that in the description of the invention, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] Addressing the issue mentioned in the background art that the height adjustment of the lifting wheel assembly in existing washing machines is not labor-saving enough, this invention provides a clothing processing device. The device includes a housing, with a bottom wheel at each of the two rear corners and a foot at each of the two front corners. A lifting wheel assembly is also located near the front of the bottom of the housing. The lifting wheel assembly includes a wheel frame, rollers mounted to the wheel frame, a vertical shaft connected to the wheel frame at its lower end, and a swing arm rotatably connected to the vertical shaft around its axis. A locking mechanism is provided between the swing arm and the vertical shaft to selectively lock the swing arm and the vertical shaft, allowing the swing arm to drive the vertical shaft to rotate synchronously in the locked state. The vertical shaft is threaded into the bottom of the housing, so that when the vertical shaft rotates around its axis, it drives the rollers to move vertically.

[0043] With this setup, when the roller height needs adjustment, the swing arm is locked to the vertical shaft via a locking mechanism. Rotating the swing arm drives the vertical shaft to rotate synchronously. Because the vertical shaft is threaded into the bottom of the housing, its rotation around its axis causes the roller to move vertically, thus adjusting the roller height. Since the swing arm rotates around the vertical shaft's axis and is connected to it in a horizontal plane, and the horizontal space below the garment processing equipment is much larger than the vertical space, the swing arm can be a relatively long rod. Furthermore, the threaded connection between the vertical shaft and the bottom of the housing, allowing the vertical shaft to rotate around its axis and drive the roller vertically, works synergistically. This means that when manually driving the swing arm to rotate around the vertical shaft's axis, which in turn drives the vertical shaft to rotate synchronously, only a small force is needed to adjust the roller height, facilitating roller height adjustment. Because the locking mechanism can selectively lock the rocker arm and the vertical axis, during the adjustment of the roller height, the rocker arm and the vertical axis are first locked by the locking mechanism. The rocker arm rotates a certain angle around the axis of the vertical axis in a first direction. Then, the lock is released, and the rocker arm rotates a corresponding angle around the axis of the vertical axis in a second direction before resetting. This process is repeated, allowing the vertical axis to move vertically. This eliminates the need for the rocker arm to rotate a full circle around the axis of the vertical axis, simplifying the operation of driving the rocker arm's rotation.

[0044] The following reference Figures 1 to 7 The garment processing equipment of the present invention will be described in detail in conjunction with a garment care machine. Figure 1 This is a schematic diagram of the structure of a garment care machine according to the first embodiment of the present invention; Figure 2 yes Figure 1 A magnified view of part A in the middle; Figure 3 This is a schematic diagram of the lifting wheel assembly of the garment care machine in the first embodiment of the present invention; Figure 4 This is a front view of the lifting wheel assembly of the garment care machine in the first embodiment of the present invention; Figure 5 It is along Figure 4 A cross-sectional view of the BB plane; Figure 6 yes Figure 5 A magnified view of part C in the middle; Figure 7 This is a schematic diagram of the assembly structure of the swing arm and vertical shaft of the lifting wheel assembly of the garment care machine in the second embodiment of the present invention.

[0045] In a first embodiment of the present invention, as Figure 1As shown, the garment care machine includes a housing 1, a door 11 pivotally connected to the front of the housing 1, a bottom wheel 21 at each of the two rear corners of the bottom of the housing 1, a foot 22 at each of the two front corners of the bottom of the housing 1, and a lifting wheel assembly 3 at the bottom of the housing 1 near the front, the lifting wheel assembly 3 being located between the two foot 22.

[0046] like Figures 2 to 5 As shown, the lifting wheel assembly 3 includes a wheel frame 31, a roller 32, a vertical shaft 33, and a swing arm 34. The roller 32 is a cylindrical roller, and the axles at both ends of the roller 32 are rotatably connected to the wheel frame 31. The lower end of the vertical shaft 33 is rotatably connected to the wheel frame 31 through a bearing 35. The swing arm 34 is rotatably connected to the vertical shaft 33 around its axis. A locking mechanism is provided between the swing arm 34 and the vertical shaft 33. The locking mechanism is used to selectively lock the swing arm 34 and the vertical shaft 33 so that the swing arm 34 drives the vertical shaft 33 to rotate synchronously in the locked state. A mounting bracket 12 is fixed to the bottom of the housing 1. The vertical shaft 33 is threadedly engaged with the mounting bracket 12 so that when the vertical shaft 33 rotates around its axis, it drives the roller 32 to move vertically. Specifically, the mounting bracket 12 is provided with a threaded hole whose axis extends vertically, and an external thread is formed on the circumferential surface of the vertical shaft 33. The external thread on the vertical shaft 33 engages with the internal thread on the inner wall of the threaded hole, so that the vertical shaft 33 can move vertically when it rotates around its axis. The internal thread on the inner wall of the threaded hole and the external thread on the vertical shaft 33 are right-hand threads.

[0047] The locking mechanism includes multiple first engaging structures distributed circumferentially along the vertical axis 33. A engaging member is provided on the rocker arm 34, which is movably connected to it. A second engaging structure is formed on the engaging member. The rocker arm 34 can engage with any of the first engaging structures through the second engaging structure to achieve locking between the rocker arm 34 and the vertical axis 33. Figure 5 and Figure 6 As shown, a ring-shaped member 36 is fixedly connected to the vertical shaft 33. Multiple toothed structures 361 are evenly distributed circumferentially on the sidewall of the ring-shaped member 36. A groove structure 362 is formed between adjacent toothed structures 361, constituting a first locking structure. The locking components include a first locking component 371 and a second locking component 372. The first end of the first locking component 371 is pivotally connected to the swing arm 34 about a first rotating shaft 3711 parallel to the vertical shaft 33. The first end of the second locking component 372 is pivotally connected to the swing arm 34 about a second rotating shaft 3721 parallel to the vertical shaft 33. The second locking structure includes a first locking block 3712 formed by the second end of the first locking component 371 and a second locking block 3722 formed by the second end of the second locking component 372.

[0048] The locking mechanism also includes a first elastic mechanism, a second elastic mechanism, and a limiting mechanism; when the first latching member 371 is not under the action of the limiting mechanism, the first latching member 371 pivots to the position where the first latching block 3712 is inserted into the slot structure 362 under the action of the first elastic mechanism; when the second latching member 372 is not under the action of the limiting mechanism, the second latching member 372 pivots to the position where the second latching block 3722 is inserted into the slot structure 362 under the action of the second elastic mechanism; the limiting mechanism can keep the first latching member 371 in the position where the first latching block 3712 is removed from the slot structure 362, and can keep the second latching member 372 in the position where the second latching block 3722 is removed from the slot structure 362. Figure 6 As shown, the first elastic mechanism includes a first spring 381. The first end of the first spring 381 is connected to the side of the first latching member 371 away from the second latching member 372, and the second end of the first spring 381 is connected to the rocker arm 34. The first spring 381 is always in a compressed state. The second elastic mechanism includes a second spring 382. The first end of the second spring 382 is connected to the side of the second latching member 372 away from the first latching member 371, and the second end of the second spring 382 is connected to the rocker arm 34. The second spring 382 is always in a compressed state. The limiting mechanism includes a cam 39 disposed between the first latching member 371 and the second latching member 372. The cam 39 is provided with a third rotating shaft 391 integrally formed therewith. The third rotating shaft 391 is pivotally connected to the rocker arm 34 and is parallel to the vertical axis 33. The upper end of the third rotating shaft 391 is fixedly connected to one end of a reversing rod 392, which is parallel to the horizontal plane.

[0049] By rotating the reversing lever 392, the cam 39 is rotated to the first position (from...). Figure 6 In the state shown (where the cam 39 is rotated 90° counterclockwise), the direction of the force exerted by the cam 39 on the first latching member 371 is perpendicular to the length direction of the first latching member 371. The direction of the force exerted by the first spring 381 on the first latching member 371 is also perpendicular to the length direction of the first latching member 371. The first latching member 371 is held in the position where the first latching block 3712 moves out of the slot structure 362 by the force of the first spring 381 and the supporting force of the cam 39. The second latching member 372 pivots to the position where the second latching block 3722 is inserted into the slot structure 362 under the action of the second spring 382. The rocker arm 34 rotates clockwise around the vertical axis 33 (refer to...). Figure 6 When the rocker arm 34 rotates (as shown in the diagram), it locks with the vertical axis 33 and drives the vertical axis 33 to rotate synchronously in a clockwise direction. At this time, the vertical axis 33 moves downwards vertically while rotating; the rocker arm 34 rotates counterclockwise around the vertical axis 33 (refer to the diagram). Figure 6 When the direction shown is rotated, it is unlocked from the vertical axis 33 and cannot drive the vertical axis 33 to rotate with the swing arm 34.

[0050] By rotating the reversing lever 392, the cam 39 is rotated to the second position. Figure 6 In the position shown, the direction of the force exerted by the cam 39 on the second latching member 372 is perpendicular to the length direction of the second latching member 372. The direction of the force exerted by the second spring 382 on the second latching member 372 is also perpendicular to the length direction of the second latching member 372. The second latching member 372 is held in the position where the second latching block 3722 moves out of the slot structure 362 by the force of the second spring 382 and the supporting force of the cam 39. The first latching member 371 pivots to the position where the first latching block 3712 is inserted into the slot structure 362 under the action of the first spring 381. The rocker arm 34 rotates counterclockwise around the vertical axis 33 (refer to...). Figure 6 When the rocker arm 34 rotates around the vertical axis 33 in the direction shown, it locks with the vertical axis 33 and drives the vertical axis 33 to rotate synchronously in the counterclockwise direction. At this time, the vertical axis 33 moves vertically upward while rotating. When the rocker arm 34 rotates around the vertical axis 33 in the clockwise direction, it is unlocked from the vertical axis 33 and cannot drive the vertical axis 33 to rotate with the rocker arm 34.

[0051] When the garment care machine needs to be operated, first move the reversing lever 392 to rotate the cam 39 to the first position. Under the pushing action of the cam 39, the first locking piece 371 rotates clockwise around the first rotating shaft 3711 (refer to...). Figure 6 (As shown in the orientation) Rotation further compresses the first spring 381. The first latching member 371 is held in the position where the first latching block 3712 moves out of the slot structure 362 by the force of the first spring 381 and the supporting force of the cam 39. The second latching member 372 is in the position where the second latching block 3722 is inserted into the slot structure 362 under the action of the second spring 382. Then, grasp the rocker arm 34 and rotate it clockwise (refer to the orientation). Figure 6 (As shown in the diagram) Rotate a certain angle, and the end face of the second locking block 3722 (i.e., the end face of the second end of the second locking member 372) exerts a force on the side wall of the toothed structure 361 that is in contact with it, pushing the ring-shaped member 36 to rotate clockwise synchronously. The vertical shaft 33 rotates clockwise synchronously with the ring-shaped member 36 by the same angle. While rotating, the vertical shaft 33 moves vertically downward by a corresponding distance, and the roller 32 and the wheel frame 31 move vertically downward accordingly. Next, grasp the swing rod 34 and rotate counterclockwise (refer to...). Figure 6 (As shown in the orientation) rotate a certain angle, the second locking member 372 slides relative to the side of the first locking member 371 and the corresponding tooth structure 361. The side of the second locking member 372 relative to the first locking member 371 generates a thrust on the corresponding tooth structure 361. The torque generated by this thrust on the vertical shaft 33 and the torque generated by the static friction between the vertical shaft 33 and the mounting bracket 12 on the vertical shaft 33 always remain equal in magnitude and opposite in direction, and the vertical shaft 33 remains stationary; then grasp the rocker arm 34 and rotate clockwise (refer to...). Figure 6Rotating a certain angle (as shown in the diagram), the end face of the second latch 3722 (i.e., the end face of the second end of the second latching member 372) exerts a force on the side wall of the toothed structure 361 in contact with it, pushing the ring-shaped member 36 to rotate clockwise synchronously. The vertical shaft 33 rotates clockwise synchronously with the ring-shaped member 36 by the same angle. While rotating, the vertical shaft 33 moves vertically downward by a corresponding distance, and the roller 32 and the wheel frame 31 move vertically downward accordingly. Then, grasp the swing rod 34 counterclockwise (refer to...). Figure 6 Rotate the garment care machine at a certain angle (as shown in the diagram)...; repeat this cycle until the roller 32 supports the ground and the foot 22 is lifted off the ground to the desired height, then push the garment care machine to the desired position.

[0052] After pushing the garment care machine to the target position, it needs to be supported by the base 22. First, move the reversing lever 392 to rotate the cam 39 to the second position. Under the pushing action of the cam 39, the second locking piece 372 rotates counterclockwise around the second rotating shaft 3721 (refer to...). Figure 6 The second spring 382 is further compressed by the rotation of the second spring 382 (as shown in the diagram). The second latching member 372 is held in the position where the second latching block 3722 moves out of the slot structure 362 by the force of the second spring 382 and the supporting force of the cam 39. The first latching member 371 pivots to the position where the first latching block 3712 is inserted into the slot structure 362 under the action of the first spring 381. Then, the rocker arm 34 is grasped and rotated counterclockwise (refer to the diagram). Figure 6 (As shown in the diagram) Rotate a certain angle, the end face of the first locking block 3712 (i.e., the end face of the second end of the first locking member 371) exerts a force on the side wall of the toothed structure 361 in contact with it, pushing the annular member 36 to rotate counterclockwise synchronously. The vertical shaft 33 rotates counterclockwise synchronously with the annular member 36 by the same angle. While rotating, the vertical shaft 33 moves vertically upward by a corresponding distance, and the roller 32 and the wheel frame 31 move vertically upward accordingly. Next, grasp the swing rod 34 clockwise (refer to...). Figure 6 (As shown in the diagram) Rotate a certain angle, the side of the first locking member 371 relative to the second locking member 372 slides relative to the tooth structure 361 at the corresponding position, and the side of the first locking member 371 relative to the second locking member 372 generates a thrust on the tooth structure 361 at the corresponding position. The torque generated by this thrust on the vertical shaft 33 and the torque generated by the static friction between the vertical shaft 33 and the mounting bracket 12 on the vertical shaft 33 always remain equal in magnitude and opposite in direction, and the vertical shaft 33 remains stationary; then grasp the rocker arm 34 and rotate counterclockwise (refer to...). Figure 6Rotating a certain angle (as shown in the diagram), the end face of the first locking block 3712 (i.e., the end face of the second end of the first locking member 371) exerts a force on the side wall of the toothed structure 361 in contact with it, pushing the annular member 36 to rotate counterclockwise synchronously. The vertical shaft 33 rotates counterclockwise synchronously with the annular member 36 by the same angle. While rotating, the vertical shaft 33 moves vertically upward by a corresponding distance, and the roller 32 and the wheel frame 31 move vertically upward accordingly. Then, grasp the swing rod 34 clockwise (refer to...). Figure 6 Rotate at a certain angle (as shown in the orientation)...; repeat this cycle until the roller 32 leaves the ground and the foot 22 supports the ground.

[0053] With the above-described structure, the height of the roller 32 can be adjusted with only a small force, making height adjustment convenient. Furthermore, there is no need for the rocker arm 34 to rotate a full circle around the vertical axis 33, simplifying the operation of driving the rocker arm 34 to rotate.

[0054] It should be noted that the internal thread on the inner wall of the threaded hole on the mounting bracket 12 and the external thread on the vertical shaft 33 are right-hand threads. This is only one specific setting, and it can be adjusted in actual applications. For example, the internal thread on the inner wall of the threaded hole on the mounting bracket 12 and the external thread on the vertical shaft 33 can be left-hand threads. Furthermore, the mounting bracket 12 is fixed to the bottom of the housing 1, and the vertical shaft 33 is threadedly engaged with the mounting bracket 12. This is also a specific setting, and it can be adjusted in actual applications. For example, a threaded hole can be provided at the bottom of the housing 1, and the vertical shaft 33 can directly engage with the bottom thread of the housing 1. Additionally, the limiting mechanism includes a cam 39 disposed between the first latching member 371 and the second latching member 372. The cam 39 is integrally formed with a third rotating shaft 391, which is pivotally connected to the rocker arm 34. The third rotating shaft 391 is parallel to the vertical axis 33. This is one specific configuration, which can be adjusted in practical applications. For example, the limiting mechanism may include a first limiting hole and a second limiting hole on the rocker arm 34, a third limiting hole and a fourth limiting hole respectively disposed on the first latching member 371, and a limiting... Position pin; when the first locking member 371 is manually pivoted to the first locking block 3712 disengagement groove structure 362 and the third limiting hole is aligned with the first limiting hole, the limiting pin is simultaneously inserted into the first limiting hole and the third limiting hole, so that the first locking member 371 is held in that position; when the second locking member 372 is manually pivoted to the second locking block 3722 disengagement groove structure 362 and the fourth limiting hole is aligned with the second limiting hole, the limiting pin is simultaneously inserted into the second limiting hole and the fourth limiting hole, so that the second locking member 372 is held in that position.Furthermore, the first elastic mechanism includes a first spring 381, with its first end connected to the side of the first latching member 371 away from the second latching member 372, and its second end connected to the swing rod 34. The first spring 381 is always in a compressed state. The second elastic mechanism includes a second spring 382, ​​with its first end connected to the side of the second latching member 372 away from the first latching member 371, and its second end connected to the swing rod 34. The second spring 382 is also always in a compressed state. This is one specific configuration, which can be adjusted in practical applications. For example, the first elastic mechanism could include a first spring, with its first end connected to the side of the first latching member 371 closer to the second latching member 372, and its second end connected to the swing rod 34. 34 connection, the first spring is always in a stretched state, the second elastic mechanism includes a second spring, the first end of the second spring is connected to the side of the second latching member 372 near the first latching member 371, the second end of the second spring is connected to the rocker arm 34, and the second spring is always in a stretched state; or the first elastic mechanism includes a first torsion spring, the first torsion spring is sleeved on the first rotating shaft 3711 and connected to the first latching member 371 and the rocker arm 34 respectively, the first torsion spring makes the first latching member 371 always maintain a tendency to rotate toward the second latching member 372, the second elastic mechanism includes a second torsion spring, the second torsion spring is sleeved on the second rotating shaft 3721 and connected to the second latching member 372 and the rocker arm 34 respectively, the second torsion spring makes the second latching member 372 always maintain a tendency to rotate toward the first latching member 371.

[0055] In a second embodiment of the invention, such as Figure 7 As shown, unlike the first embodiment, the first end of the first latching member 371 and the first end of the second latching member 372 are fixedly connected to a common rotating shaft 373, which is parallel to the vertical shaft 33 and pivotally connected to the swing arm 34. A vertical lever 375 is connected to the side wall of the common rotating shaft 373 away from the vertical shaft 33 via a connecting rod 374. By moving the lever 375, the first latching member 371 and the second latching member 372 can simultaneously rotate around the common rotating shaft 373, thereby allowing one of the first latching blocks 3712 and the second latching block 3722 to be selectively inserted into the slot structure 362. Before rotating the swing arm 34 to drive the vertical shaft 33 to rotate, the first latching block 3712 or the second latching block 3722 needs to be manually inserted into the slot structure so that when the swing arm 34 rotates in the corresponding direction, the swing arm 34 locks with the vertical shaft 33, and when the swing arm 34 rotates in the opposite direction, the lock is released.

[0056] In another feasible embodiment, unlike the first embodiment, the first elastic mechanism, the second elastic mechanism, and the limiting mechanism of the first embodiment are not provided. In this case, it is necessary to manually pivot the first latching member 371 to the position where the first latching block 3712 is inserted into the slot structure 362 and to manually pivot the first latching member 371 to the position where the first latching block 3712 is removed from the slot structure 362.

[0057] In another feasible embodiment, unlike the first embodiment, the locking mechanism includes a plurality of first engaging structures distributed circumferentially along the vertical axis 33. A engaging member is provided on the rocker arm 34 and movably connected thereto. A second engaging structure is formed on the engaging member. The rocker arm 34 can engage with any of the first engaging structures through the second engaging structure to achieve locking between the rocker arm 34 and the vertical axis 33. An annular member 36 is fixedly connected to the vertical axis 33. A plurality of toothed structures 361 are evenly distributed circumferentially on the sidewall of the annular member 36. The shape of the toothed structures 361 is... Figure 7 The fan-shaped structure shown has a groove structure 362 formed between two adjacent tooth structures 361, and the groove structure 362 constitutes a first snap-fit ​​structure. The snap-fit ​​component includes a slider that is slidably connected to the rocker arm 34 along the length direction of the rocker arm 34, and a second snap-fit ​​structure is formed at the end of the slider near the vertical axis 33, and the axis of the slider intersects the axis of the vertical axis 33.

[0058] When it is necessary to lock the rocker arm 34 and the vertical shaft 33, manually push the slider towards the vertical shaft 33 so that the end of the slider near the vertical shaft 33 inserts into the slot structure 362. At this time, rotating the rocker arm 34 will cause the vertical shaft 33 to rotate synchronously. When it is necessary to release the lock between the rocker arm 34 and the vertical shaft 33, manually move the slider away from the vertical shaft 33 so that the end of the slider near the vertical shaft 33 moves out of the slot structure 362. It should be noted that the tooth structure 361 can also be used as the first locking structure, with a slot adapted to the tooth structure 361 at the end of the slider near the vertical shaft 33, and the slot at the end of the slider near the vertical shaft 33 serving as the second locking structure.

[0059] In another feasible embodiment, unlike the first embodiment, the locking mechanism includes a threaded hole extending radially along the vertical axis 33 on the rocker arm 34 and a set screw that engages with the threaded hole. When it is necessary to lock the rocker arm 34 and the vertical axis 33, the set screw is screwed to move it axially toward the vertical axis 33 until the end of the set screw abuts against the surface of the vertical axis 33, thereby locking the rocker arm 34 and the vertical axis 33. When it is necessary to release the lock between the rocker arm 34 and the vertical axis 33, the set screw is screwed to move it axially away from the vertical axis 33 until the end of the set screw disengages from the surface of the vertical axis 33, thereby releasing the lock between the rocker arm 34 and the vertical axis 33.

[0060] In some other feasible embodiments, unlike the embodiments described above, the lower end of the vertical shaft 33 is fixedly connected to the wheel frame 31. However, when moving the roller 32 downwards to support it on the ground, the roller 32 needs to be rotated with the vertical shaft 33 until the axis of the roller 32 is perpendicular to the direction of movement of the garment care machine, so as to facilitate the movement of the garment care machine.

[0061] In some other feasible embodiments, unlike the embodiments described above, the lower end of the vertical shaft 33 is fixedly connected to the wheel frame 31, and the roller 32 is configured as a spherical roller. When the vertical shaft 33 is driven to rotate by the rocker arm 34, causing the roller 32 to move vertically downward to the supporting ground, there is no need to consider the rotation direction of the roller 32, which makes it more convenient to adjust the height of the roller 32.

[0062] It should also be noted that although this invention is described in conjunction with a garment care machine, the garment processing equipment of this invention is not limited to a garment care machine. The garment processing equipment of this invention can also be a washing machine, a dryer, a shoe washing machine, a washer-dryer combo, etc.

[0063] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
