DETAILED DESCRIPTION

[0030] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0031] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0032] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0033] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0034] In the related art, in order to realize the automatic opening of the door body, a plurality of elastic top pillars are usually arranged on the door body. After closing the door, the elastic top pillars are compressed to store energy. After opening the door, the energy is released to push the door body outward. However, this design method will cause a plurality of exposed elastic top pillars on the door body, which is not beautiful in appearance, and has a complex structure and poor assembly process. The door body is initially pushed open with great force and speed, which brings a bad experience to the user. In order to solve this problem, the present application proposes a clothing processing device.

[0035] For ease of understanding, the direction in which the clothes treating apparatus faces the user is referred to as the front direction, and the direction in which the clothes treating apparatus faces away from the user is referred to as the rear direction.

[0036] See also Figures 1 to 3 A clothes processing device may include a housing 1, which is the external integral structure of the clothes processing device. The housing 1 is a hollow structure with an internal space, in which other component structures of the clothes processing device may be arranged, such as a circuit structure, an air duct structure, a driving mechanism, and a drainage structure. The housing 1 may be in the shape of a hollow rectangular parallelepiped or a hollow cylindrical body, and of course, is not limited to the above shapes.

[0037] In some embodiments, a mounting groove 11 may be provided on the front side of the box body 1. The mounting groove 11 is concave like other parts of the front side of the box body 1. A clothing delivery port 12 is formed in the middle of the mounting groove 11 to facilitate delivery of clothing to be processed.

[0038] In some embodiments, the clothing processing device may include a drum, which is arranged in the internal space of the housing 1 and is used to process clothing, such as washing clothing or drying clothing, etc. The drum has a clothing processing cavity with an opening on the front side, and clothing is put into the clothing processing cavity for processing through a clothing delivery port 12 provided on the mounting groove 11 of the housing 1. Accordingly, the drum has an opening, and the opening of the drum is arranged opposite to the clothing delivery port 12, so that it is convenient to directly put the clothing to be processed into the clothing processing cavity of the drum through the clothing delivery port 12.

[0039] The drum body may include an outer drum and an inner drum, the inner drum is hollow to form a clothing processing cavity, the inner drum is arranged in the inner cavity of the outer drum, the outer drum is arranged in the box body 1, the axes of the inner drum and the outer drum are opened in the front-to-back direction, and the clothing loading port 12 is opened on the front side plate of the box body 1. An opening is arranged on the peripheral wall of the inner drum, the inner drum is connected with the inner cavity of the outer drum through the opening, the inner drum can discharge washing water to the outer drum through the opening, and the washing water is discharged from the box body 1 through the drainage structure connected to the outer drum. According to the functional distinction of the clothing processing device, the clothing processing device can be a drum washing machine, a dryer or a washing and drying machine, etc. In this embodiment, the clothing processing device is taken as an example of a drum washing machine for explanation.

[0040] In some embodiments, the clothing processing device may include a door body 2, which is rotatably connected to the box body 1 to open or close the clothing loading port 12. It can be understood that the position of the door body 2 corresponds to the clothing loading port 12, and the area of ​​the door body 2 should be able to cover the clothing loading port 12 so as to be able to close the clothing loading port 12, so that the box body 1 is an enclosed space when in operation.

[0041] In some embodiments, the door body 2 may include a front door panel 21 , which is a plate-shaped structure. When the door body 2 closes the clothing loading port 12 , the front door panel 21 faces the user and serves as the appearance surface of the door body 2 .

[0042] In some embodiments, the door body 2 may include a rear door panel 22, which is a plate-shaped structure that matches the shape of the front door panel 21. The rear door panel 22 is opposite to the front door panel 21, and the two are connected by fasteners. When the door body 2 closes the clothing inlet 12, the rear door panel 22 faces the clothing inlet 12. As the back side of the door body 2, an installation space is formed between the front door panel 21 and the rear door panel 22 for setting fasteners and other components. It is understandable that the front door panel 21 and the rear door panel 22 can be annular as a whole, and the middle opening is used to install the door glass 23. The edge of the door glass 23 is stuck in the installation space, and the door glass 23 can facilitate the user to observe the washing situation in the drum.

[0043] See also Figures 6 to 9 In some embodiments, the drum washing machine may further include a hinge assembly 3, which is used to realize the rotation of the door body 2 relative to the cabinet 1, so that the door body 2 is opened or closed, making it convenient for users to open and close the door body 2.

[0044] In some embodiments, the hinge assembly 3 may include a hinge body 31, which is fixedly connected to the box body 1. The hinge body 31 and the box body 1 are fixedly connected by fasteners, and specifically can be connected to the bottom of the mounting groove 11 of the box body 1. In this way, when the door is closed, the hinge body 31 is hidden in the mounting groove 11, and there are no exposed components on the appearance of the box body 1, which is more beautiful.

[0045] In some embodiments, the hinge assembly 3 may include a hinge reinforcement plate 32, which is fixed to the door body 2. The hinge reinforcement plate 32 is fixedly connected to the door body 2 by fasteners. Specifically, the hinge reinforcement plate 32 can be connected to the installation space between the front door panel 21 and the rear door panel 22. In this way, the hinge reinforcement plate 32 is hidden in the door body 2 and not exposed, which is more beautiful.

[0046] In some embodiments, the hinge assembly 3 may include a hinge shaft, and the hinge body 31 and the hinge reinforcement plate 32 are rotatably connected through the hinge shaft. The hinge body 31 and the hinge reinforcement plate 32 are respectively provided with a first rotation hole 313 and a second rotation hole 322 for the hinge shaft to penetrate, so as to realize the relative rotation between the hinge body 31 and the hinge reinforcement plate 32, thereby rotating to open or close the door body 2.

[0047] In some embodiments, the hinge assembly 3 may include a torsion spring 33, which is sleeved on the hinge shaft, and has two opposite ends, one end of the torsion spring 33 is connected to the hinge body 31, and the other end of the torsion spring 33 is connected to the hinge reinforcement plate 32. The torsion spring 33 is a spiral spring, and the torsion spring 33 can store and release angular energy or statically fix a structure by rotating the force arm around the central axis of the spring body.

[0048] It is understandable that by arranging the torsion spring 33 on the hinge shaft, the torsion spring 33 is in a compressed state when the door body 2 closes the clothing loading port 12, and will accumulate energy. When the door body 2 is unlocked and opened, the torsion spring 33 will release the torque. At this time, the door body 2 will slowly and automatically spring open under the action of the torsion spring 33 until it opens and closes to a preset angle. The door body 2 is stopped and no longer rotates. At this time, the torsion spring 33 can still be in a compressed state to prevent the door body 2 from swinging at will. The preset angle can be the maximum opening and closing angle of the door body 2. At this time, the maximum opening range of the door body 2 is usually between 100° and 120°. In this embodiment, the preset angle is 110°.

[0049] In some embodiments, the hinge body 31 may include a connecting plate body 311, which is fixedly connected to the box body 1. The connecting plate body 311 is a plate-like structure so that it can fit on the bottom of the mounting groove 11 to save installation space. Since people are accustomed to opening and closing the door left or right, the connecting plate can be fixed on the left or right bottom of the mounting groove 11. In this way, when opening the door, the door body 2 can be opened and closed left and right, which is more ergonomic.

[0050] In some embodiments, the hinge body 31 may include a hinge cantilever 312 protruding from the edge of the connecting plate body 311, and the hinge cantilever 312 is provided with the above-mentioned first rotation hole 313, wherein the first rotation hole 313 passes through the hinge cantilever 312 to cooperate with the hinge shaft.

[0051] In some embodiments, an opening groove 321 is provided on the edge of the hinge reinforcement plate 32, and the opening of the opening groove 321 should be larger than the volume of the hinge cantilever 312, so that the hinge cantilever 312 is conveniently set in the opening groove 321, and the hinge cantilever 312 can rotate in the opening groove 321. The above-mentioned second rotating hole 322 is provided at the groove wall of the opening groove 321 corresponding to the position of the first rotating hole 313, and the hinge shaft is passed through the first rotating hole 313 and the second rotating hole 322, so that the hinge cantilever 312 can rotate relative to the hinge reinforcement plate 32.

[0052] In some embodiments, in order to make the hinge rotate more stably and the door body 2 and the box body 1 have better connectivity, two hinge cantilevers 312 are provided at intervals, and two opening slots 321 are provided at intervals, and correspond one to one with the hinge cantilevers 312, so as to reduce the possibility of eccentricity of the hinge axis. Of course, in some embodiments, three or more hinge cantilevers 312 and opening slots 321 can be provided to ensure that the hinge body 31 and the hinge reinforcement plate 32 are reliably connected.

[0053] In some embodiments, the torsion spring 33 is a double-torsion structure, and the torsion spring 33 includes two spiral portions 331 and a connecting section 332 located between the two spiral portions 331 for connecting the two spiral portions 331. The two spiral portions 331 are sleeved on the portion of the hinge shaft located between the two hinge cantilevers 312, and can limit the axial direction of the torsion spring 33 to prevent the torsion spring 33 from moving in the axial direction of the hinge shaft. The inner ends of the two spiral portions 331 are connected to the two ends of the connecting section 332, the outer ends of the two spiral portions 331 are connected to the hinge cantilever 312, and the connecting section 332 is connected to the hinge reinforcement plate 32, so that the torsion force of the torsion spring 33 is accumulated more when compressed, and can better push the door body 2 to open when released, and the automatic door opening effect is better.

[0054] In some embodiments, the connecting section 332 includes two first sections 3321 and a second section 3322 axially spaced apart along the hinge axis, one end of the two first sections 3321 are respectively connected to the inner end of the spiral portion 331, and the other ends of the two first sections 3321 are respectively connected to one end of the second section 3322, so that the second section 3322 can be farther away from the hinge axis than the spiral section, and the first section 3321, the second section 3322 and the spiral section can be wound as a whole. In this way, the second section 3322 can store more energy when the torsion spring 33 is in a compressed state, and has greater torque when released.

[0055] In some embodiments, a convex portion 323 is formed on the edge of the hinge reinforcement plate 32 between the two opening grooves 321, and the two side walls of the convex portion 323 constitute one side groove wall of the opening groove 321, and the second section 3322 of the connecting section 332 abuts against the side of the convex portion 323 facing the door body 2, so that when the door body 2 is opened, since the hinge body 31 is in a stationary state following the box body 1, the torque released by the second section 3322 acts on the convex portion 323, pushing the convex portion 323 and the hinge reinforcement plate 32 to rotate outward, thereby driving the door body 2 to open. Among them, the convex portion 323 is a part of the hinge reinforcement plate 32, formed by the part left after the opening groove 321 is opened, and the convex portion 323 protrudes relative to the groove bottom of the opening groove 321.

[0056] In some embodiments, the first section 3321 of the connecting section 332 is bent away from the spiral portion 331 to form a bend in the first section 3321. This allows the connecting section 332 to be bent as a whole. When the second section 3322 abuts against the protrusion 323, it is like hooking on the surface of the protrusion 323, and the connection is more stable.

[0057] In some embodiments, ears 314 are provided on opposite ends of the two hinge cantilevers 312, and the ears 314 are provided with connection holes parallel to the hinge axis, and the outer ends of the spiral parts 331 are inserted into the corresponding connection holes, so as to achieve connection with the hinge body 31. The ears 314 protrude in the radial direction relative to the hinge cantilever 312 so as to be staggered with the spiral parts 331, so as to facilitate the insertion of the outer ends of the spiral parts 331, and the outer ends of the spiral parts 331 can be linear structures so as to be inserted deeper into the connection holes.

[0058] In some embodiments, the hinge assembly 3 may further include a limit member 34, which is disposed on the hinge reinforcement plate 32. The limit member 34 abuts against the hinge body 31 when the angle between the hinge reinforcement plate 32 and the hinge body 31 is at a preset angle to limit the door body 2 from rotating outward. At this time, the opening angle of the door body 2 cannot be further increased. By setting the limit member 34 to limit the extreme position of the rotation of the door body 2, the door body 2 can be prevented from colliding with the box body 1 due to excessive opening angle, thereby protecting the door body 2 and the box body 1.

[0059] In some embodiments, the limit member 34 is specifically arranged on one end of the groove wall of the opening groove 321 away from the groove bottom thereof. The limit member 34 is sheet-shaped and extends from the groove wall of the opening groove 321 along the axial direction of the hinge axis. When the door body 2 rotates to a preset angle, the limit member 34 is located on the side of the hinge cantilever 312 facing the box body 1 and abuts against it, thereby limiting the hinge reinforcement plate 32 from continuing to rotate relative to the hinge body 31.

[0060] Continue to see Figure 3 , Figure 4 and Fig.10 In some embodiments, the push-open assembly 4 may include a top cover 42 disposed on the box body 1, and the elastic column 41 presses against the top cover 42 when the door body 2 closes the clothing loading port 12. The top cover 42 is provided to withstand the force of the elastic column 41 to prevent the box body 1 from being damaged. A reinforcing rib 424 is provided on the side of the top cover 42 away from the elastic column 41, so that the structural strength of the top cover 42 is increased by the reinforcing rib 424.

[0061] In some embodiments, the top cover 42 is cylindrical, including a support column 421 and a cover plate 422 disposed at one end of the support column 421, a reinforcing rib 424 is disposed in the support column 421, a plug hole for inserting the support column 421 is disposed on the box body 1, the edge of the cover plate 422 exceeds the support column 421, an avoidance hole is provided on the peripheral wall of the support column 421, and an elastic rib 423 is provided on the hole wall of the avoidance hole, and the elastic rib 423 has a certain elasticity in the radial direction of the support column 421. In a natural state, the free end of the elastic rib 423 protrudes from the peripheral wall of the support column 421, and the distance between the elastic rib 423 and the cover plate 422 is the thickness of the box body 1, so that when installing, the support column 421 is inserted along the plug hole until the cover plate 422 abuts against the front side of the box body 1, and at this time, the free end of the elastic rib 423 presses against the inner side of the box body 1 to clamp the top cover 42 on the plug hole. Of course, in some embodiments, the top cover 42 may also be the structure of the box body 1 itself, and the box body 1 is structurally reinforced at the portion in contact with the elastic column 41 .

[0062] It is understandable that the top cover 42 can also be made of a cushioning material, such as rubber, to play a cushioning role, reduce the impact caused by the elastic column 41 when closing the door, reduce the noise caused by the impact, and improve the user experience.

[0063] In some embodiments, the elastic column 41 includes a guide sleeve 411 and a top column 412 disposed on the door body 2. One end of the guide sleeve 411 is open, and the open end of the guide sleeve 411 faces the box body 1, forming a guide channel inside. The top column 412 is slidably disposed in the guide sleeve 411 along the guide channel. A compression spring 413 is disposed between the top column 412 and the guide sleeve 411, and the energy of the compression spring 413 is used to make the top column 412 slide along the guide channel. When the door body 2 closes the clothing inlet 12, the end of the top column 412 away from the door body 2 presses against the top cover 42, and the compression spring 413 is in a compressed state. In this way, when the door body 2 is opened, the compression spring 413 releases energy, and the door body 2 is pushed outward, driving the door body 2 to rotate outward, and under the joint action of the torsion spring 33 in the hinge assembly 3, the door body 2 is automatically opened to a preset angle.

[0064] In some embodiments, the guide sleeve 411 is arranged in the installation space between the front door panel 21 and the rear door panel 22. A mounting plate is formed by extending in the radial direction of the guide sleeve 411. The mounting plate is fixedly connected to the rear door panel 22 by fasteners. An opening is opened on the rear door panel 22 for the top column 412 to pass through. The open end of the guide sleeve 411 abuts against the inner side of the rear door panel 22 to realize axial limitation of the guide sleeve 411.

[0065] In some embodiments, the bottom end of the top column 412 extends radially to form a limiting ring 415, and the outer wall of the limiting ring 415 is connected to the inner wall of the guide sleeve 411, thereby achieving a guiding effect on the top column 412, and the limiting ring 415 can be abutted against the inner wall of the rear door panel 22 to limit the travel of the top column 412 and prevent it from falling out of the opening on the rear door panel 22.

[0066] In some embodiments, a boss 414 is further provided at the bottom of the guide sleeve 411, and the interior of the top column 412 is hollow. One end of the compression spring 413 is sleeved on the boss 414, and the other end extends into the top column 412. The boss 414 is used to limit the compression spring 413, and the top column 412 can also slide in the guide sleeve 411 through the compression spring 413.

[0067] In some embodiments, the drum washing machine further comprises a lock hook 5 arranged on the door body 2 and a door lock 6 arranged on the housing 1. The lock hook 5 and the door lock 6 have a locked state and an unlocked state. When the door body 2 closes the clothing delivery port 12, the lock hook 5 and the door lock 6 are locked, and the door body 2 is in a closed state and cannot be opened at will. When the door body 2 opens the clothing delivery port 12, the lock hook 5 and the door lock 6 are unlocked. At this time, the user can control the door lock 6 and the lock hook 5 to unlock. The compressed torsion spring 33 and the compression spring 413 respectively drive the hinge assembly 3 and the push-pull assembly 4 to move, so that the door body 2 is automatically opened, so that the user can handle the clothes in the drum.

[0068] In some embodiments, in order to realize multiple door opening methods, such as electric touch door opening, manual push door opening, etc., a door lock 6 with a push-open function can be used. The door lock 6 has a built-in elastic structure. The door lock 6 and the lock hook 5 can store elastic energy after being locked, and release the elastic potential energy after opening and unlocking the door to assist the door body 2 to bounce open, thereby improving the softness of the door opening and closing feel and improving the user experience.

[0069] To sum up, the drum washing machine of this embodiment is designed with a hinge assembly 3 with torsion at the connection between the door body 2 and the housing 1, and a torsion spring 33 is added to the hinge shaft. When the door is closed, the torsion spring 33 is twisted to store energy, and when the door is opened, the torsion spring 33 releases energy and cooperates with the elastic column 41 in the push-pop assembly 4 to pop the door body 2 open, thereby achieving the effect of automatic door opening and reducing the use of the elastic top column 412. The door body 2 has a beautiful shape, a simple structure and is easy to assemble. The force and speed of the door popping up are relatively gentle, and the door opening experience is good.
