[0002] The door panels of clothing care machines are typically bonded to the door body. Because they are located on the surface of the machine and frequently come into contact with the human body, they are susceptible to staining, corrosion, and collisions, which can damage the door panels. Furthermore, to meet room decoration requirements, the door panels also need to be able to be changed into different patterns or colors. However, conventional bonded door panels are not easy to replace.

[0003] Therefore, there is an urgent need in the art for a door assembly and a clothing care device to solve the above problems. Summary of the Invention

[0004] The present invention aims to solve the above technical problem, that is, to solve the problem that door panels are difficult to replace.

[0005] In a first aspect, the present invention provides a door assembly, comprising a door panel and a door body, wherein one of the door panel and the door body is provided with a first protrusion, and the other is provided with a first receiving hole;

[0006] The first protrusion can extend into the first receiving hole so that the door panel is connected to the door body;

[0007] The first protrusion can be disengaged from the first receiving hole to separate the door panel from the door body.

[0008] In a specific embodiment of the above-mentioned door assembly, the bottom surface of the first receiving hole is a downwardly inclined surface, and the bottom surface of the first protrusion matches the inclined surface;

[0009] When the first protrusion extends into the first receiving hole, the bottom surface of the first protrusion fits with the bottom surface of the first receiving hole, so that the door panel fits with the door body.

[0010] In a specific embodiment of the above-mentioned door assembly, the door assembly further includes a roller and a lead, the roller being rotatably disposed on the door body, one end of the lead being connected to the roller, and the other end being detachably connected to the first protrusion;

[0011] When the roller rotates, the lead wire can be wound onto the roller, and the lead wire pulls the first protrusion to move upward, so that the bottom surface of the first protrusion is separated from the bottom surface of the first receiving hole.

[0012] In a specific embodiment of the above-mentioned door body assembly, the door body assembly further includes a gear and a drive assembly, the gear is fixedly disposed on the roller, and the drive assembly can drive the gear to rotate so that the lead is wound onto the roller.

[0013] In a specific embodiment of the above-mentioned door assembly, the driving assembly includes a rocker and a core shaft, and one end of the rocker is sleeved outside the roller so that the rocker can rotate around the roller;

[0014] When the rocker rotates around the roller, the core shaft extending into the groove between the teeth of the gear can cause the gear to rotate.

[0015] In a specific embodiment of the above-mentioned door assembly, the driving assembly further includes an elastic member;

[0016] The core shaft is slidably connected to the rocker, one end of the elastic member is connected to the rocker, and the other end is connected to the core shaft, and the elastic member can drive the outer end of the core shaft to extend into the inter-tooth groove of the gear.

[0017] In a specific embodiment of the above-mentioned door assembly, the outer end surface of the core shaft is an inclined surface, and the core shaft is rotatably connected to the rocker to control the direction of the inclined surface;

[0018] When the core shaft rotates around the roller in a first direction, the protruding teeth of the gear can make the core shaft slide along the inclined surface;

[0019] When the core shaft rotates about the roller in the second direction, the core shaft can cause the gear to rotate.

[0020] In a specific embodiment of the above-mentioned door body assembly, the side wall of the core shaft is provided with a second protrusion, and the rocker is provided with a clearance groove. The second protrusion extends out of the rocker through the clearance groove, and the first direction and the second direction can be switched by rotating the second protrusion.

[0021] In a specific embodiment of the above-mentioned door assembly, the door assembly further comprises a ratchet and a pawl, wherein the ratchet is fixedly disposed on the roller, and the pawl is rotatably disposed on the door body;

[0022] When the pawl abuts against the ratchet, the ratchet can only rotate in one direction, so that the roller can only rotate in the direction of winding the lead.

[0023] In a second aspect, the present invention provides a clothing care device, which includes the above-mentioned door assembly.

[0024] When the above technical solution is adopted, one of the door panel and the door body is provided with a first protrusion, and the other is provided with a first receiving hole. The first protrusion can extend into the first receiving hole to connect the door panel to the door body. The first protrusion can also be disengaged from the first receiving hole to separate the door panel from the door body. This detachable connection structure between the door panel and the door body makes the door panel easy to install and remove.

[0025] Furthermore, the bottom surface of the first receiving hole is an inclined surface, and the bottom surface of the first protrusion is also an inclined surface. When the first protrusion extends into the first receiving hole, the bottom surface of the first receiving hole and the bottom surface of the first protrusion are aligned, and the surface of the door panel and the surface of the door body are also aligned. This arrangement makes it easier to install and position the door panel and the door body.

[0026] Furthermore, a roller is provided in the door body, and a lead on the roller can be connected to the first protrusion. The roller can be rotated to reel in the lead, and the first protrusion and the door panel can be lifted upwards, so that the first protrusion is separated from the first receiving hole.

[0027] Furthermore, a gear is fixedly mounted on the roller, and a drive assembly is capable of rotating the gear, thereby rotating the roller. The drive assembly includes a rocker, a core shaft, and an elastic member. By rotating the rocker, the elastic member drives the core shaft into the groove between the teeth of the gear, and the core shaft rotates with the rocker, driving the gear. Furthermore, a ratchet is fixedly mounted on the roller, and a pawl abuts the ratchet, limiting the roller's unidirectional rotation. This, in conjunction with the drive assembly, allows the roller to rotate unidirectionally, thereby winding the lead wire. BRIEF DESCRIPTION OF THE DRAWINGS

These terms are used solely for ease of description and are not intended to indicate or imply that the device or component described must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0053] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "installed," "disposed," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0054] In order to solve the problem that the door panel is difficult to replace, this embodiment discloses a clothing care device. Figure 1 The clothing care device includes a door assembly, which includes a door panel 1 and a door body 2. The door panel 1 is detachably connected to the door body 2, so that the door panel 1 of the clothing care device is easy to replace.

[0055] It should be noted that regarding the clothing care device, although the door assembly in this embodiment is arranged on the clothing care device, this arrangement is not a limitation of the present invention. Without deviating from the principles of the present invention, those skilled in the art may also arrange the door assembly on other devices in other embodiments, such as refrigerators, wardrobes, cabinets, room doors 2, etc. These do not deviate from the basic principles of the present invention and therefore fall within the scope of protection of the present invention.

[0056] The specific detachable connection structure between the door panel 1 and the door body 2 is as follows: a first protrusion 11 is provided on the door panel 1, and the first protrusion 11 is specifically a plate-shaped structure extending obliquely downward. Figure 2 The door body 2 is provided with a first receiving hole 21, which is specifically a through hole. The bottom surface of the first receiving hole 21 is a downwardly inclined surface 71, see Figure 3 and Figure 4 The bottom surface of the first protrusion 11 matches the bottom surface of the first receiving hole 21. When the first protrusion 11 extends into the first receiving hole 21, the bottom surface of the first protrusion 11 fits with the bottom surface of the first receiving hole 21, and the surface of the door panel 1 and the door body 2 also fit together, so that the door panel 1 is connected to the door body 2. Figure 5When the door panel 1 needs to be disassembled, the first protrusion 11 is disengaged from the first receiving hole 21, and the door panel 1 can be separated from the door body 2. Figure 6 .

[0057] In order to make it easier to separate the door panel 1 from the door body 2, the door panel 1 assembly further includes a roller 3, a lead, a gear, a driving assembly, a ratchet 9 and a pawl 10.

[0058] Reference Figures 4 to 7 The door body 2 is provided with a cavity 22 inside, and the first receiving hole 21 is connected to the cavity 22. The roller 3 is rotatably provided in the cavity 22, and the roller 3 is provided above the first receiving hole 21. One end of the lead is connected to the roller 3. When the roller 3 rotates, the lead can be wound onto the roller 3. The other end of the lead can be detachably connected to the first protrusion 11. Specifically, the first protrusion 11 is provided with a second through hole 12, see Figure 2 The lead wire can pass through the second through hole 12 and then be tied to connect the lead wire to the first protrusion 11. Figure 5 and Figure 6 Furthermore, two baffles 31 are spaced apart on the roller 3, and the lead wire is wound between the two baffles 31. Figure 8 The baffle 31 can limit the position of the lead wire on the roller 3, preventing the lead wire from being wound around other structures and affecting the rotation of the roller 3 or the operation of other components.

[0059] Regarding the connection structure between the lead and the first protrusion 11, it should be noted that although the lead in this embodiment is connected to the first protrusion 11 by passing through the second through hole 12 and then tying a knot, this setting method is not a limitation of the present invention. Without deviating from the principles of the present invention, those skilled in the art may also adopt other settings in other embodiments, for example: setting a hook on the lead, and connecting the second through hole 12 of the first protrusion 11 through the hook. This does not deviate from the basic principles of the present invention and therefore falls within the scope of protection of the present invention.

[0060] Regarding the roller 3, it should be noted that although the roller 3 in this embodiment is disposed above the first receiving hole 21, this arrangement is not a limitation of the present invention. Without departing from the principles of the present invention, those skilled in the art may adopt other arrangements in other embodiments. For example, the roller 3 may be disposed below the first receiving hole 21, and a second roller may be disposed above the first receiving hole 21, with the middle portion of the lead wire passing around the second roller. This arrangement may also achieve the effect of lifting the door panel 1 when the lead wire is wound. This does not depart from the basic principles of the present invention and therefore falls within the scope of protection of the present invention.

[0061] When installing the door panel 1, first pass the lead wire through the first receiving hole 21 and then connect it to the first protrusion 11. Then extend the first protrusion 11 into the first receiving hole 21 to install the door panel 1 on the door body 2. When removing the door panel 1, rotate the roller 3 to reel the lead wire onto the roller 3. See Figure 5 As the lead wire is tightened, the lead wire will pull the first protrusion 11 and the door panel 1 upward, so that the bottom surface of the first protrusion 11 is separated from the bottom surface of the first receiving hole 21, so that the door panel 1 can be disassembled. Figure 6 .

[0062] Further, refer to Figures 8 to 10 The gear and ratchet 9 are fixedly mounted on the roller 3. The driving assembly can drive the gear to rotate. The pawl 10 is rotatably mounted in the cavity 22. When the pawl 10 abuts against the ratchet 9, the roller 3 can only rotate in one direction. Figure 11 The pawl 10 can also be moved to separate the pawl 10 from the ratchet wheel 9 so that the roller 3 can rotate in the reverse direction.

[0063] When the lead needs to be reeled in, the drive assembly drives the gear to rotate forward, causing roller 3 to rotate forward, tightening the lead onto roller 3. The drive assembly then rotates in the reverse direction, causing pawl 10 and ratchet wheel 9 to abut, preventing roller 3 from rotating in the reverse direction. The drive assembly can then be rotated forward again, causing roller 3 to continue rotating forward to reel in the lead. By repeating this process, the roller can continue to rotate forward, reeling the lead onto roller 3. This arrangement allows the gear and roller 3 to rotate continuously in one direction even when space on door body 2 is limited.

[0064] Regarding the drive assembly, it should be noted that although the drive assembly in this embodiment drives the roller 3 to rotate unidirectionally by reciprocating rotation, this arrangement is not a limitation of the present invention. Without departing from the principles of the present invention, those skilled in the art may also adopt other arrangements in other embodiments. If the drive assembly can drive the roller 3 to rotate continuously in one direction, there is no need to set the ratchet 9 and the pawl 10. For example, when the space inside the door body 2 is large, the drive assembly includes a motor, a driving gear and a driven gear, a driving gear is set on the motor shaft, and a driven gear is set on the roller 3. The driving gear and the driven gear are engaged, and the rotation of the motor can drive the roller 3 to rotate continuously in one direction. This does not deviate from the basic principles of the present invention and therefore falls within the scope of protection of the present invention.

[0065] The driving assembly includes a rocker 6 , a core shaft 7 and an elastic member 8 .

[0066] Reference Figures 8 to 10 One end of the rocker 6 is sleeved on the roller 3, and the rocker 6 can rotate around the roller 3. Figure 7The door body 2 is provided with an opening 23 on its surface, and the opening 23 is connected to the cavity 22. The operator can contact the rocker 6 through the opening 23 to rotate the rocker 6. Figures 12 to 14 The rocker 6 has a slot 62 inside, into which the mandrel 7 passes, allowing the mandrel 7 to slide. The slot 62 slides toward the gear. In other words, the mandrel 7 can move closer to or further away from the gear as it slides along the slot 62. The elastic member 8 is specifically a cylindrical spring, with one end connected to the inner end of the mandrel 7 and the other end connected to the rocker 6. This elastic member 8 forces the outer end of the mandrel 7 to abut the gear.

[0067] Regarding the elastic member 8, it should be noted that although the elastic member 8 in this embodiment is a cylindrical spring, this arrangement is not a limitation of the present invention. Without departing from the principles of the present invention, those skilled in the art may adopt other arrangements in other embodiments, such as an air spring or multiple butterfly springs. This does not deviate from the basic principles of the present invention and thus falls within the scope of protection of the present invention.

[0068] During the rotation of the rocker 6 around the roller 3, the elastic member 8 can drive the outer end of the core shaft 7 to extend into the groove between the teeth of the gear. Thereafter, the rocker 6 continues to rotate around the roller 3, and the core shaft 7 can drive the gear to rotate, thereby driving the roller 3 to rotate.

[0069] Furthermore, the outer end surface of the core shaft 7 is a bevel 71, see Figure 12 The chute 62 of the rocker 6 is cylindrical, and the shape of the core shaft 7 is also cylindrical, so the core shaft 7 can rotate in the chute 62, thereby controlling the contact surface between the outer end of the core shaft 7 and the gear.

[0070] When the outer end of the core shaft 7 extends into the groove between the teeth, the rocker 6 can drive the core shaft 7 to rotate around the roller 3. If the core shaft 7 rotates around the roller 3 in the first direction, in other words, the side wall of the outer end of the core shaft 7 rotates toward the convex teeth, which is equivalent to Figure 12 If the core shaft 7 rotates clockwise around the roller 3, the core shaft 7 can make the gear rotate. If the core shaft 7 rotates along the second direction around the roller 3, in other words, the inclined surface 71 at the outer end of the core shaft 7 rotates toward the convex teeth of the gear, it is equivalent to Figure 12 The mandrel 7 in the gear rotates counterclockwise around the roller 3, and the convex teeth can make the mandrel 7 slide along the inclined surface 71, in other words, make the mandrel 7 slide away from the gear direction and compress the spring. In this case, the mandrel 7 can't drive the gear to rotate.

[0071] Further, continue to refer to Figures 12 to 14The side wall of the core shaft 7 is provided with a second protrusion 72, which is specifically a rod-shaped structure protruding from the side wall of the core shaft 7. The second protrusion 72 and the core shaft 7 body form a T-shaped rod or an L-shaped rod. The operator can turn the second protrusion 72 to rotate the core shaft 7, so that the inclined surface 71 faces left or right. Specifically, refer to Figure 12 When the inclined surface 71 faces right, the first direction of the mandrel 7 is clockwise rotation around the roller 3, and the second direction of the mandrel 7 is counterclockwise rotation around the roller 3. When the inclined surface 71 faces left, the first direction of the mandrel 7 is counterclockwise rotation around the roller 3, and the second direction of the mandrel 7 is clockwise rotation around the roller 3. In summary, the second protrusion 72 can switch the first direction and the second direction of the mandrel 7.

[0072] Reference Figure 10 The surface of the rocker 6 is provided with a clearance groove 61, and the second protrusion 72 extends to the outside of the rocker 6 through the clearance groove 61 so that the operator can move the second protrusion 72. In addition, the clearance groove 61 is provided with sufficient space so that the second protrusion 72 can move in the clearance groove 61 when the core shaft 7 slides.

[0073] The following describes the working principle of the door assembly:

[0074] When installing the door panel 1 on the door body 2, first connect one end of the lead wire to the first protrusion 11 on the door panel 1, then insert the first protrusion 11 into the first receiving hole 21, so that the bottom surface of the first protrusion 11 fits with the bottom surface of the first receiving hole 21, so that the door panel 1 fits with the door body 2, thus completing the installation of the door panel 1. For details, see Figure 1 and Figure 5 .

[0075] When the door panel 1 needs to be disassembled, the pawl 10 is first rotated to make the pawl 10 contact the ratchet 9, thereby preventing the roller 3 from rotating in the opposite direction. Figure 11 Then, turn the rocker 6 forward, and the elastic member 8 pushes the core shaft 7 to slide toward the gear, so that the outer end of the core shaft 7 extends into the groove between the teeth of the gear. Figure 12 Then, the second protrusion 72 is moved to rotate the core shaft 7, and the direction of the inclined surface 71 at the outer end of the core shaft 7 is adjusted. When the rocker 6 drives the core shaft 7 to rotate in the positive direction around the roller 3, the side wall of the outer end of the core shaft 7 rotates toward the convex teeth of the gear, which is equivalent to Figure 12 The mandrel 7 in the middle rotates clockwise around the gear, causing the gear and roller 3 to rotate forward. Then continue to rotate the rocker 6 forward, causing the mandrel 7 to drive the gear to rotate forward, and the roller 3 also rotates forward, causing the lead wire to be wound onto the roller 3. When the rocker 6 rotates forward to the end, rotate the rocker 6 in the reverse direction. When the rocker 6 drives the mandrel 7 to rotate in the reverse direction around the roller 3, the inclined surface 71 at the outer end of the mandrel 7 rotates toward the convex tooth, which is equivalent to Figure 12The core shaft 7 in the middle rotates counterclockwise around the gear, and the convex teeth can make the core shaft 7 move along the inclined surface 71, in other words, make the core shaft 7 slide in the direction away from the gear, and compress the elastic member 8 at the same time. And in the process of the rocker 6 rotating in the opposite direction, the core shaft 7 passes through a plurality of convex teeth and grooves between the teeth, and the core shaft 7 can slide along the outer edge of the gear, and the core shaft 7 will not push the gear. And the pawl 10 and the ratchet 9 limit the rotation direction of the roller 3, so in the process of the rocker 6 rotating in the opposite direction, the gear and the roller 3 remain stationary. When the rocker 6 rotates in the opposite direction to the end, the rocker 6 is rotated forward again, driving the gear and the roller 3 to rotate forward and rewind the lead. By repeating the above process many times, the roller 3 continues to rotate forward, and all the leads are rewound onto the roller 3. In the process of rewinding the lead, the lead will pull the first protrusion 11 and the door panel 1 upward, so that the bottom surface of the first protrusion 11 is separated from the bottom surface of the first accommodating hole 21, so that the door panel 1 can be disassembled, see for details. Figure 6 When the door panel 1 moves upward, stop turning the rocker 6. Then turn the pawl 10 to separate the pawl 10 from the ratchet 9; and move the second protrusion 72 to rotate the core shaft 7 and adjust the direction of the inclined surface 71 at the outer end of the core shaft 7. When the roller 3 rotates in the opposite direction, the convex teeth rotate toward the inclined surface 71 at the outer end of the core shaft 7, which is equivalent to Figure 12 The middle gear rotates clockwise around the roller 3, and the convex teeth can push the core shaft 7 to slide away from the gear along the inclined surface 71, so that the core shaft 7 will not affect the reverse rotation of the gear and the roller 3. In this state, the roller 3 can rotate in the reverse direction. Afterwards, move the door panel 1 so that the first protrusion 11 disengages from the first receiving hole 21, so that the door panel 1 is separated from the door body 2. During the process of separating the door panel 1 from the door body 2, the lead connected to the first protrusion 11 will be stretched, and the roller 3 will also rotate in the reverse direction, so that the lead wound on the roller 3 is released. The lead is then separated from the first protrusion 11, thereby completing the process of disassembling the door panel 1.

[0076] Thus far, the technical solutions of the present invention have been described in conjunction with 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 may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
