[0022] Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0023] The word "exemplary" used herein means "serving as an example, embodiment or illustration". Any embodiment described herein as "exemplary" is not necessarily to be interpreted as superior or better than other embodiments. In addition, "horizontal" and "vertical" used in this application are not limited to horizontal and vertical in a strict sense, but also include situations where the object is tilted at a certain angle but does not affect the implementation of the present invention.

[0024] The present invention is described below by taking the application of the present invention to a drum washing machine as an example. However, those skilled in the art will appreciate that the present invention can also be applied to other clothing processing devices such as a dryer, a washing and drying machine, and other household electrical appliances such as a dishwasher.

[0025] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0026] Example 1

[0027] like Figure 1 As shown, the clothing treatment device 1 comprises a locking component 10, a door assembly 20 and a main body assembly 30. Among them, the front panel of the main body assembly 30 has an opening for putting in and taking out clothing, the door assembly 20 is freely opened and closed on the main body assembly 30, and can open and cover the opening of the main body assembly 30, and the locking component 10 can lock the door assembly 20 to the main body assembly 30, so that the user cannot open the door assembly 20.

[0028] The clothes processing device 1 also has the following Figure 2 The control unit 40 shown. The control unit 40 can be arranged in the door body assembly 20, or in the main body assembly 30, or a part of it can be arranged in the door body assembly 20 and the other part of it can be arranged in the main body assembly 30. The control unit 40 is used to control the operation of washing, rinsing, dehydration, etc. of the clothing processing device 1, and is also configured to be able to control the locking component 10. In the present invention, the control unit 40 is configured to enable the locking component 10 to unlock the door body assembly after the operation of the clothing processing device 1 is completed. As a result, a closed space is no longer formed inside the clothing processing device 1, and the air entering from the outside is used to reduce the temperature and humidity inside the clothing processing device 1, thereby reducing the risk of the clothes processed in the clothing processing device 1 being contaminated again.

[0029] The structure of the locking component 10 can adopt any suitable structure, and the present invention does not impose any limitation on this. In the present application, a structure in which a lock tongue and a lock hole cooperate to perform locking is exemplarily adopted, and this structure is used as an example for explanation. The locking component 10 may include a lock tongue 101 provided on the door body assembly 20 and a lock hole 102 provided on the main body assembly 30. Figure 3 As shown, when the lock tongue 101 is inserted into the lock hole 102, the door assembly 20 is locked to the main assembly 30. Figure 4 As shown, after the operation of the laundry processing device 1 is finished, the control unit 40 activates a motor (not shown) to drive the lock tongue 101 to rotate and escape from the lock hole 102, thereby releasing the lock of the door assembly 20.

[0030] As those skilled in the art will appreciate, the present invention is not limited to the examples described above. Optionally, the lock tongue 101 and the lock hole 102 can be exchanged, that is, the lock tongue 101 is arranged on the main body assembly 30, and the lock hole 102 is arranged on the door assembly 20; the lock tongue 101 and the lock hole 102 can also adopt any other suitable structure.

[0031] In addition, the laundry processing apparatus 1 further includes a force-applying component for applying a force to the door assembly 20 in a direction to open the door assembly 20. After the control unit 40 causes the locking component 10 to unlock the door assembly 20, the force-applying component can open the door assembly 20 to expand the opening range of the door assembly 20, thereby further reducing the temperature and humidity inside the laundry processing apparatus 1.

[0032] As an example of the force applying member, the force applying member may be a hinge for freely opening and closing the door assembly 20 on the main assembly 30. The hinge may be provided on a side of the door assembly 20 opposite to the locking assembly 10. Figure 5-8 One example of a hinge 200 that can be used as a force applying member is shown.

[0033] like Figure 5 , 6 As shown, the hinge 200 according to the present embodiment includes: a first rotating shaft 240 , a second rotating shaft 260 , a rotating portion 230 , a first connecting portion 210 , a torsion spring 220 , a second connecting portion 250 , and a reinforcing portion 270 .

[0034] The second rotation shaft 260 is arranged in parallel (including substantially parallel) with the first rotation shaft 240 .

[0035] One end of the rotating part 230 is installed on the first rotating shaft 240 at two positions along the axial direction of the first rotating shaft, and the other end opposite to the one end is installed on the second rotating shaft 260 at two positions. An arc-shaped extension part 2301 extending along an arc shape is provided between the one end and the other end. The rotating part 230 can rotate with the first rotating shaft 240 as the central axis.

[0036] One end of the first connection part 210 is mounted on the first rotating shaft 240, and the edge part 2101 of the other end opposite to the one end is in an arc shape protruding toward the first rotating shaft 240. The edge part 2101 is closer to the first rotating shaft 240 in the central part in the axial direction of the first rotating shaft 240 than in the two ends. The edge part has an extension part 2102 at both ends in the axial direction of the first rotating shaft 240, which protrudes in a direction perpendicular to the first rotating shaft 240 and extends along an arc protruding in the same direction as the protruding direction of the arc-shaped extension part 2301 of the rotating part 230. The front end of the extension part 2102 is provided with a threaded part 2103 as a first fixing part, and the first connection part 210 can be fixed by a screw through the threaded part 2103. The first connection part 210 is exemplarily a metal casting of aluminum alloy or zinc alloy. In addition, a limiting part 2104 ( ) for abutting against the rotating part 230 to limit the further rotation of the rotating part 230 is also provided at a position of the first connection part 210 opposite to the rotating part 230. Figure 7 , 8 The limiting portion 2104 is configured to have at least a portion protruding toward the rotating portion 230.

[0037] The torsion spring 220 is installed at a position between two positions of the first rotating shaft 240 where the rotating part 230 is installed. The swing arm 221 of the torsion spring 220 is engaged with the rotating part 230, and the fixed arm 222 of the torsion spring 220 is engaged with the first connecting part 210. By arranging the torsion spring 220 in this way, the torsion spring force acts on the rotating part 230, so that when the lock of the door body assembly 20 is released, the rotating part 230 rotates and drives the door body assembly 20 to open, so that the hinge 200 can function as a force-applying component.

[0038] One end of the second connection part 250 is mounted on the second rotating shaft 260, and can rotate around the second rotating shaft 260 as the center axis. The edge part 2501 of the other end of the second connection part 250 opposite to the one end is in an arc shape protruding toward the second rotating shaft 260, and the center part of the edge part 2501 in the axial direction of the second rotating shaft 260 is closer to the second rotating shaft 260 than the two ends. The arc shape of the edge part 2501 can be substantially the same as or different from the arc shape of the edge part 2101. The two ends of the edge part 2501 are provided with a threaded part 2502 as a second fixing part, and the second connection part 250 can be fixed by screws through the threaded part 2502.

[0039] The reinforcing part 270 is mounted on both ends of the first rotating shaft 240 and can rotate around the first rotating shaft 240 as the central axis. The reinforcing part 270 is generally L-shaped, including a first part and a second part that are perpendicular to each other and connected by a curved part, wherein the first part is mounted on the first rotating shaft 240. A threaded part 2701 is formed on the second part of the reinforcing part 270 as a third fixing part, and the reinforcing part 270 can be fixed by a screw through the threaded part 2701.

[0040] The following references Figure 7 , 8 The hinge 200 is installed in the laundry processing device 1. Figure 7 As shown, the front panel 100 installed on the front surface side of the main body assembly 30 includes a panel portion 1001, an annular recess 1002, an opening portion 1003, a flange 1004 and a vertical portion 1005. The panel portion 1001 is generally flat and constitutes the front surface of the main body assembly seen when the user opens the door assembly 20. The annular recess 1002 is recessed toward the inside of the washing machine in accordance with the shape of the door assembly 20, and is used to accommodate the door assembly 20 when the door assembly 20 is closed. An opening 10021 is formed in the annular recess 1002 for the rotating portion 230 of the hinge 200 to pass through. The opening portion 1003 is surrounded by the annular recess 1002, opposite to the opening of the drum not shown, and is formed into a generally circular shape in the same shape as the opening of the drum, for the user to take out and put in the laundry. The flange 1004 extends from the outer edge of the panel portion 1001 perpendicularly to the panel portion 1001 toward the inside of the washing machine, and may be formed only at a position required for installing the hinge 200, or may be formed on one side or the entire circumference of the panel portion 1001. The erection portion 1005 extends from the edge of the flange 1004 on the opposite side of the panel portion 1001 toward the opening portion 1003 in parallel with the panel portion 1001, and may be formed only at a position required for installing the hinge 200, or may be formed on one side or the entire circumference of the flange 1004. Optionally, the panel portion 1001, the annular recess 1002, the opening portion 1003, the flange 1004, and the erection portion 1005 may be formed integrally.

[0041] The door assembly 20 can be opened and closed freely to cover the opening 1003 of the front panel, and has a convex portion whose cross-sectional area decreases as it approaches the inside of the washing machine. The door assembly 20 may include a window member and a front plate and a rear plate for fixing the window member. Similar to the opening 1003, the window member is formed to have a circular cross-section to match the shape of the opening of the drum. When the door assembly 20 is closed, the window member is opposite to the opening 1003 and the opening of the drum, and the user can observe the state of the laundry in the drum through the window member and the opening 1003.

[0042] The first connection part 210 and the reinforcing part 270 of the hinge 200 are fixed to the front panel of the main body assembly 30, and the second connection part 250 is fixed to the door body assembly 20, so that the door body assembly 20 is installed on the main body assembly 30 so as to be opened and closed freely. The hinge 200 is installed on the back side of the front panel, so when the user opens the door body assembly 20, only the rotating part 230 extending from the opening 10021 can be observed, and the first connection part 210, the torsion spring 220, the first rotating shaft 240 and the reinforcing part 270, etc. cannot be observed.

[0043] The first shaft 240 is disposed at the connection portion between the panel portion 1001 and the flange 1004 of the front panel 100. The first connection portion 210 extends from the first shaft 240 along the panel portion 1001 to the connection portion between the panel portion 1001 and the annular recess 1002. The edge portion 2101 of the first connection portion 210 is formed to match the shape of the outer edge of the annular recess 1002 and extends along the outer edge of the annular recess 1002. The extension portion 2102 of the first connection portion 210 is formed to match the shape of the annular recess 1002 and extends along the back side of the annular recess 1002. The first connection portion 210 is fixed to the annular recess 1002 by a screw through the threaded portion 2103. The reinforcing portion 270 is fixedly mounted on the first rotating shaft 240 in a manner perpendicular to the first connecting portion 210 . The first portion of the reinforcing portion 270 is arranged along the flange 1004 , and the second portion is arranged along the erecting portion 1005 and is fixed to the erecting portion 1005 by means of screws through the threaded portion 2701 .

[0044] like Figure 7 As shown, when the door assembly 20 is in a closed state, the torsion spring 220 is in a deformed state. Therefore, once the lock of the door assembly 20 is released, the torsion spring force of the torsion spring 220 is released, the swing arm 221 pushes the rotating part 230 to rotate, and drives the door assembly 20 to open, switching to Figure 8 Status shown.

[0045] The above examples illustrate a two-axis hinge that can be opened in two stages and has a larger opening range. However, as those skilled in the art can understand, a single-axis hinge can also function as a force-applying component. Optionally, the single-axis hinge as a force-applying component may include: a rotating shaft; a first connecting portion, which is mounted on the rotating shaft and fixed to the main body component 30; a second connecting portion, which is mounted on the rotating shaft and fixed to the door body component 20, and the second connecting portion can rotate around the rotating shaft as the central axis; and a torsion spring, which includes a fixed arm engaged with the first connecting portion and a swing arm engaged with the second connecting portion. It can be arranged that when the door body component 20 is in a closed state, the torsion spring is in a deformed state. After the control unit 40 causes the locking component 10 to release the lock on the door body component 20, the torsion spring releases the torsion spring force, and the swing arm pushes the second connecting portion to rotate around the rotating shaft, and drives the door body component 20 to open.

[0046] In addition to the torsion spring in the hinge as described above, other forms of elastic components can also be used to implement the above-mentioned force-applying component. As long as the elastic component is in a deformed state when the door body assembly 20 is in a closed state, after the control unit 40 causes the locking component 10 to release the lock on the door body assembly 20, the elastic component can use the force generated by its elastic deformation to open the door body assembly 20.

[0047] Optionally, the elastic member may include a spring disposed between the door assembly 20 and the main body assembly 30 and fixed to the door assembly 20 side or the main body assembly 30 side. When the door assembly 20 is in a closed state, the spring is squeezed by the door assembly 20 and the main body assembly 30 and is in a compressed state. After the lock of the door assembly 20 is released, the force generated by the elastic deformation of the spring is released, pushing the door assembly 20 to open.

[0048] In addition to the elastic member, the force-applying component can be realized in other ways. Optionally, the force-applying component includes a motor and an actuator, and the actuator, driven by the motor, applies force to the door assembly 20 to open the door assembly 20. The motor and the actuator can be arranged in the door assembly 20 or in the main assembly 30. The actuator can adopt any suitable structure.

[0049] Optionally, the actuating portion may be a rod-shaped member extending toward the door assembly 20 or the main body assembly 30 under the drive of a motor, and the door assembly 20 may be opened by directly pushing the door assembly 20 or the reaction force obtained by pushing the main body assembly 30.

[0050] In addition, in the above examples, there is only one force-applying component, but as those skilled in the art will appreciate, multiple force-applying components may be provided. The present invention does not impose any restrictions on the structure, position and / or number of the force-applying components, and they may be appropriately arranged according to actual needs, as long as they can apply force to the door assembly 20 in a direction that causes the door assembly 20 to open.

[0051] Example 2

[0052] Embodiment 2 adds a limiting component 300 for limiting the relative position between the door assembly 20 and the main body assembly 30 on the basis of embodiment 1. By using the limiting component 300, the door assembly 20 can be stabilized at a specified position other than the closed position and the fully open position relative to the main body assembly 30, avoiding safety accidents or damage to the door assembly 20 due to the sudden and large opening of the door assembly 20 after the operation is completed and the door assembly 20 is in a free state.

[0053] like Fig. 9As shown, the limiting component 300 and the locking component 10 are arranged in an up-down direction. Figure 9-12 As shown, the limiting component 300 comprises: a magnet member 301, a housing 302, a cover 303, a spring 304, a pin 305, a spring 306 and a sleeve 307. The magnet member 301, the housing 302, the cover 303 and the spring 304 are fixedly mounted on the back side 31 of the front panel of the main assembly 30 as a whole in such a way that the flat bottom surface 3011 of the magnet member 301 is exposed from the through hole formed in the front panel of the main assembly 30.

[0054] The magnet member 301 is composed of a substantially cubic magnet and a covering shell that does not isolate the magnet and covers the magnet. The bottom surface 3011 of the magnet member 301, which is one end surface, is formed as a substantially flat surface, and a convex portion 3012 is formed at a substantially central position on the top surface of the end surface opposite to the one end surface. A convex portion 3013 is formed at a predetermined position in the height direction of the magnet member 301 in a manner that covers the entire circumference of the four side surfaces.

[0055] The shell 302 is formed into a roughly square cylindrical shape with a bottom, and an opening portion is formed on the bottom surface 3021, the opening shape of which is roughly the same as the bottom surface shape of the magnet component 301 and the opening area is slightly larger than the cross-sectional area of ​​the magnet component 301. The portion of the magnet component 301 below the protrusion 3013 can pass through the opening portion of the bottom surface 3021 of the shell 302, and the protrusion 3013 is blocked by the bottom surface 3021 and will not pass through the opening portion.

[0056] The cover 303 is also formed into a substantially square bottomed cylinder, and covers the housing 302 in such a manner that the cylinder wall 3032 surrounds the cylinder wall 3022 of the housing 302 and the top surface 3031 covers the opening of the housing 302. On the surface of the top surface 3031 facing the magnet member 301, a convex portion 3033 is provided at a position corresponding to the convex portion 3012 of the magnet member 301.

[0057] The spring 304 has one end fixed to the convex portion 3012 of the magnet member 301 in a natural state, and the other end fixed to the convex portion 3033 of the cover 303 .

[0058] The magnet member 301 can move through the opening of the bottom surface 3021 of the housing 302, and the movement of the magnet member 301 can be prevented by the contact between the protrusion 3013 and the bottom surface 3021 of the housing. The spring 304 connected to the magnet member 301 can be elastically deformed as the magnet member 301 moves.

[0059] In addition, the pin 305, the spring 306 and the sleeve 307 are fixedly installed as a whole on the side of the door assembly 20 facing the main assembly 30. The back plate 21 of the door assembly 20 has a substantially circular opening, and a vertical portion 22 is formed from the opening in a direction away from the main assembly 30 and substantially perpendicular to the back plate 21, and flanges 23 and 24 are formed at both ends of the vertical portion 22.

[0060] The pin 305, the spring 306 and the sleeve 307 are inserted into the space surrounded by the upright portion 22. The top surface 3051 of the pin 305 is located on the side of the flange 23 facing the main body component 30, and can be restricted from moving toward the side opposite to the magnet component 301 by abutting against the flange 23. The spring 306 is located on the side of the flange 23 away from the main body component 30, and can also be restricted from moving toward the magnet component 301 by abutting against the flange 23. The flange portion 3072 of the sleeve 307 can be restricted from moving toward the side opposite to the magnet component 301 by abutting against the flange 24.

[0061] The pin shaft 305 comprises: a top surface 3051, which is formed into a roughly circular flat plate shape, and its area when viewed from above is smaller than the area of ​​the flat bottom surface 3011 of the magnet member 301; a shaft portion 3052, which is formed into a cylindrical shape with a diameter smaller than the diameter of the top surface 3051 on one side of the top surface 3051; a thin diameter portion 3054, which is formed into a cylindrical shape with a diameter smaller than the diameter of the shaft portion 3052 at one end of the shaft portion 3052 away from the top surface 3051; and a connecting portion 3053, which is formed into a cylindrical shape with a diameter smaller than the diameter of the shaft portion 3052 and larger than the diameter of the thin diameter portion 3054 at one end of the thin diameter portion 3054 away from the shaft portion 3052, and is used for connecting to the sleeve 307.

[0062] The top surface 3051 of the pin 305 is arranged to face the flat bottom surface 3011 of the magnet member 301, and at least the top surface 3051 is formed of a material that can attract the magnet member 301 by magnetic force. When the top surface 3051 of the pin 305 and the bottom surface 3011 of the magnet member 301 are engaged with each other, a magnetic attraction force of, for example, 30 Newtons or more can be provided between them. The spring 306 can be installed in a natural state on the shaft portion 3052 and the thin diameter portion 3054 of the pin 305.

[0063] The spring 306 is attached to the pin 305 in a natural state.

[0064] The sleeve 307 includes a cylindrical portion 3071 and a flange portion 3072. The cylindrical portion 3071 has an inner diameter substantially the same as the diameter of the connecting portion 3053 of the pin 305, and is connected to the connecting portion 3053 of the pin 305 by interference fit to fix the connecting portion 3053. The flange portion 3072 protrudes radially outward at one end of the cylindrical portion 3071. When the connecting portion 3053 of the pin 305 is fixed to the cylindrical portion 3071 of the sleeve 307, the flange portion 3072 faces the end surface of the shaft portion 3052 of the pin 305 via the thin-diameter portion 3054.

[0065] The position limiting component 300 of the above structure has a first state (i.e., an initial state) in which the magnet member 301 and the top surface 3051 of the pin shaft 305 are mutually attracted and engaged by magnetic force and the springs 304 and 306 are in a natural state. Fig.10 ); the magnet member 301 and the top surface 3051 of the pin 305 are mutually attracted by magnetic force and engage with each other and the springs 304 and 306 are elastically deformed in the second state ( Fig.11 ); and the third state where the magnet member 301 is separated from the pin 305 ( Fig.12 ).

[0066] In the clothes processing apparatus 1, the stopper member 300 functions as follows.

[0067] When the door assembly 20 of the laundry processing device 1 is in the closed position, the limiting component 300 is in the closed position. Fig.10 The first state is shown.

[0068] After the operation of the laundry processing device 1 is finished, when the control unit 40 causes the locking component 10 to unlock the door assembly 20, the force-applying component applies force to the door assembly 20 to rotate and open the door assembly 20. As the door assembly 200 rotates and opens, the flange 23 provided on the upright portion 22 of the door assembly 20 compresses the spring 306, and the force applied by the compression spring 306 to the pin 305 and further to the magnet member 301 causes the spring 304 to be stretched. When the door assembly 20 is opened to a specified angle, that is, when the magnet member 301 and the pin 305 have traveled the maximum stroke, the door assembly 20 is in a closed position. Fig.11 The second state is shown.

[0069] The spring 304 also acts as a buffer component, slowing down the door assembly 20 when it is automatically opened to prevent the door assembly 20 from escaping the attraction of the magnet component 301 at an excessive speed. It can also provide a buffer when the door assembly 20 is closed to prevent the magnet component 301 from directly hitting the mounting component, thereby protecting the magnet component 301 and preventing noise.

[0070] In the second state, the flat bottom surface 3011 of the magnet member 301 is still engaged with the top surface 3051 of the pin shaft 305, and the protrusion 3013 of the magnet member 301 abuts against the bottom surface 3021 of the shell 302 and its movement is restricted. At this time, the force applied to the springs 304 and 306 in the direction of opening the door body assembly 20 by the force-applying component is greater than or equal to the force generated by the elastic deformation of the springs 304 and 306 in the direction of closing the door body assembly 20, and is less than the sum of the force generated by the elastic deformation of the springs 304 and 306 in the direction of closing the door body assembly 20 and the magnetic attraction between the magnet member 301 and the pin shaft 305.

[0071] In this state, the door assembly 20 is stably fixed at the rotation angle by the magnetic attraction between the magnet member 301 and the pin shaft 305, for example, the maximum gap between the door assembly 20 and the main body assembly 30 reaches an angle of 20 mm.

[0072] In the case where the door body assembly 20 is to be further opened from this state, it is necessary to apply a force (for example, 30 Newtons) in the opening direction of the door body assembly 20 that exceeds the sum of the force generated by the elastic deformation of the springs 304 and 306 in the direction of closing the door body assembly 20 and the magnetic attraction between the magnet member 301 and the pin 305 minus the difference between the force applied to the springs 304 and 306 in the direction of opening the door body assembly 20 through the hinge. When such a force is applied, the bottom surface 3011 of the magnet member 301 separates from the top surface 3051 of the pin 305 and the limiting component 300 enters the third state.

[0073] At this time, the door body assembly 20 becomes able to rotate freely, and the magnet component 301 returns to the initial position where the bottom surface 3011 and the front panel of the main body assembly 30 are roughly on the same plane under the action of the rebound force of the spring 304. The pin shaft 305 returns to the initial position where the top surface 3051 and the back side panel 21 of the door body assembly 20 are roughly on the same plane under the action of the rebound force of the spring 306.

[0074] In this way, when the limiting component 300 is in the third state and the door body assembly 20 can rotate freely, the magnet component 301 and the pin shaft 305 are restored under the action of the spring rebound force without protruding to the front panel of the main body assembly 30 and the back panel of the door body assembly 20, thereby not affecting the normal use of the user and enhancing the overall appearance of the clothing processing device.

[0075] When the door assembly 20 is closed, the door assembly 20 can be rotated freely. As the door assembly 20 is returned, the magnetic attraction between the magnet member 301 and the pin 305 interacts and moves in the direction of mutual engagement. At this time, the spring 304 is stretched and elastically deformed, and the moving speed of the pin 305 is faster than the moving speed of the door assembly 20, and the spring 306 is pressed and deformed by the flange 23 of the door assembly 20.

[0076] The spring 304 and the spring 306 are elastically deformed, and the limiting component 300 becomes Fig.11 In the second state shown, as described above, the door assembly 20 can be stabilized at a specified angle when the limiting component 300 is in the second state.

[0077] When further closing the door assembly 20 , the force applied in the direction of closing the door assembly 20 needs to exceed the force applied by the force-applying component to the door assembly 20 in the opening direction, so as to overcome the force of the force-applying component in the opening direction to close the door assembly 20 .

[0078] In this way, by using the limiting component 300, the door assembly 20 of the clothing treatment device 1 can be stably fixed at a specified position between the closed position and the fully open position, thereby preventing safety accidents or damage to the door assembly 20 due to the door assembly 20 suddenly opening significantly after the operation is completed and the door assembly 20 being in a free state. Optionally, the limiting component 300 can allow a certain gap, such as 20 mm, between the door assembly 20 and the main body assembly 30, so as to achieve free exchange of air between the inside and outside of the clothing treatment device 1, and enable ventilation and sterilization.

[0079] For example, experiments show that the number of colony groups in the clothing processing device 1 is about 100 when clothing processing is just completed. When the door body assembly is closed in this state, the number of colony groups becomes about 800 after a specified time. When the door body assembly is opened to a specified position relative to the main body assembly, the number of colony groups drops to about 20 after a specified time. When the door body assembly is fully opened, the number of colony groups drops to about 0 after a specified time.

[0080] The above is an exemplary description of the position limiting component 300. As examples of the first engaging member and the second engaging member, the magnet member 301, the pin 305, and the sleeve 307 are illustrated above; as examples of the stop member, the convex portion 3013 and the wall portion of the bottom surface 3021 surrounding the opening portion, the flange portion 3072, and the flange 23 are illustrated above; as examples of the reset member, the spring 304 and the spring 306 are illustrated above.

[0081] However, the present invention is not limited to this, and various modifications can be made without departing from the spirit and scope of the invention.

[0082] Alternatively, only the stopper member is provided, while the reset member is eliminated. For example, the springs 304 and 306 are eliminated. Alternatively, the springs 304 and 306 are retained to be used as both the stopper member and the reset member, while the convex portion 3013 and the wall portion surrounding the opening portion of the bottom surface 3021, as well as the flange portion 3072 and the flange 23 are eliminated. In this case, when the force generated by the elastic deformation of the springs 304 and 306 is equal to the force received by the mutually engaged magnet member 301, the pin 305 and the sleeve 307, the magnet member 301, the pin 305 and the sleeve 307 are restricted from further movement, thus playing the role of the stopper member.

[0083] Alternatively, one of the magnet member 301, the pin 305 and the sleeve 307 may be fixedly disposed on the main body assembly 30 or the door body assembly 20, while the other of the magnet member 301, the pin 305 and the sleeve 307 may be disposed on the door body assembly 20 or the main body assembly 30 in a relatively movable manner.

[0084] Alternatively, the structures of the limiting component 300 on the main component 30 and the door body component 20 sides may be made the same. For example, the structures on the main component 30 and the door body component 20 sides may both adopt any one of the structures exemplified on the main component 30 side and the structures exemplified on the door body component 20 side.

[0085] In the above examples, an elastic body such as an elastically deformable rope may be used instead of the springs 304 and 306 .

[0086] Alternatively, in the above example, one of the springs 304 and 306 may be omitted.

[0087] In the above example, the magnet constituting the magnet member 301 may be a sandwich magnet, an electromagnet that generates magnetism when electricity is supplied, or the like, and is not particularly limited as long as it can generate magnetic force.

[0088] In the above example, the top surface 3051 of the pin 305 and the bottom surface 3011 of the magnet member 301 provide a magnetic attraction force of 30 Newtons or more to each other, but the present invention is not limited thereto and can be arbitrarily set as needed.

[0089] In the above example, the bottom surface of the magnet component 301 is roughly square and the top surface of the pin shaft 305 is roughly circular, but this is not limited to this. There is no particular limitation on the shapes of the bottom surface, top surface, etc. of these components, and they can be set arbitrarily as needed.

[0090] In the above examples, the springs 304 and 306 are in the natural state in the initial state as an example for explanation, but it is not limited to this. It can also be that in the first state as the initial state, at least one of the springs 304 and 306 is in a non-natural state and is in a state of elastic deformation, and the second state is a state in which the spring is further elastically deformed or restored to a natural state. For example, the state of the spring 304 can be adjusted by setting a protrusion on the inner side of the barrel wall 3022 of the housing 302, and by limiting the magnet member 301 between the protrusion and the bottom surface 3021 of the housing 302, and the initial state of the spring 306 can be adjusted by adjusting the length of the shaft 3052 of the pin 305. Those skilled in the art can arbitrarily set the state of the spring in the initial state and the way to set the spring state as needed.

[0091] Alternatively, a locking tongue and a locking hole, or a buckle and a flange, etc. may be used as the first engaging member and the second engaging member, respectively, instead of the magnet member 301, the pin 305, and the sleeve 307, so that the first engaging member and the second engaging member are engaged with each other in other ways such as mutual engagement. In this case, the first engaging member and the second engaging member may be separated by the control of the clothing processing device 1 or the manual operation of the user. In addition, if the application environment of the present invention does not require the separation of the first engaging member and the second engaging member, it may also be configured so that the first engaging member and the second engaging member are engaged with each other in an inseparable manner.

[0092] In the above example, the magnet member 301 and the spring 304 are installed on the main body assembly 30, and the pin 305, the sleeve 307 and the spring 306 are installed on the door assembly 20, but the installation can also be reversed.

[0093] For example, as a modified example, the pin 305 may be installed on the back side of the front panel of the main assembly 30 in a manner that the top surface 3051 and at least a portion of the shaft portion 3052 protrude from the front panel of the main assembly 30, and the magnet member 301 and the spring 304 may be installed on the door assembly 20. The same effect can be achieved in the case of reverse installation.

[0094] In addition, in the above examples, the installation position of the limiting component 300 is not limited to above the locking component 10, and can be set at any position as needed.

[0095] In addition, in the above example, the maximum gap between the door body assembly 20 and the main body assembly 30 reaches 20 mm, but it is not limited to this. It can be adjusted to less than 20 mm or greater than 20 mm as needed by adjusting the stroke of the limiting component of the limiting component 300, such as the spring 304, 106.

[0096] Example 3

[0097] The difference between Example 3 and Example 2 is that one component is used to realize the functions of the force-applying component and the position-limiting component at the same time. Fig.13 , 14 As shown, the force-applying component may include a motor (not shown) and an actuator, and the actuator may be a connecting rod structure 280. One end of the connecting rod structure 280 is provided at the door body assembly 20, and the other end is provided at the main body assembly 30. The connecting rod structure 280 can be deformed under the drive of the motor to move the door body assembly 20 relative to the main body assembly 30 (acting as a force-applying component), and at the same time, the door body assembly 20 can be maintained at the position after the movement, so that the door body assembly 20 is stabilized at a specified position other than the closed position and the fully open position relative to the main body assembly 30 (acting as a limiting component).

[0098] Fig.13 The connecting rod structure 280 is shown when the door assembly 20 is in a closed state. Fig.14 It is shown that after the lock of the door assembly 20 is released, the link mechanism 280 pushes the door assembly 20 outward under the drive of the motor, so that the door assembly 20 is opened and the door assembly 20 is kept in the current position. A plurality of link structures 280 can be arranged in the circumferential direction of the door assembly 20 to achieve the following Fig.14 The effect of the door assembly 20 translating outwardly relative to the main body assembly 30 is shown.

[0099] The connecting rod structure 280 is only an example of the actuating part of this embodiment, and the present invention is not limited thereto. The actuating part of this embodiment may also be a structure that is extended and shortened under the drive of a motor, or a structure that is expanded and reduced under the drive of a motor. In addition, the number and position of the actuating part are not limited, and only one or more actuating parts may be provided, and the actuating parts may be provided at any suitable position, such as near a hinge or near a locking component.

[0100] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terms used herein are selected to best explain the principles of the embodiments, practical applications, or technical improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
