[0070] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0071] The following refers to Figures 1 - 10 Describe the hinge assembly 2000 according to an embodiment of the present invention.

[0072] As Figures 1 - 10 shown, the hinge assembly 2000 according to an embodiment of the present invention includes a hinge base 210 and a hinge blade 220. The hinge base 210 has an opening 214, and a rotating shaft 250 is provided at the opening 214. The hinge blade 220 is rotatably provided on the hinge base 210 through the rotating shaft 250.

[0073] Moreover, at least a part of the hinge blade 220 penetrates through the opening 214. With such a setting, when the hinge assembly 2000 is installed in a device, not only can at least a part of the hinge assembly 2000 be hidden, but also the door body 3000 can be embedded.

[0074] The hinge assembly 2000 further includes a damping device 270. The damping device 270 is sleeved on the rotating shaft 250 and is used to generate a damping force to make the hinge blade 220 stay at a preset position.

[0075] For example, the hinge blade 220 can rotate between a first position and a second position to ensure that the included angle between the hinge blade 220 and the hinge base 210 can change. The damping device 270 can make the hinge blade 220 stay at a preset position. The preset position can be between the first position and the second position, or the preset position can be the second position. When the hinge assembly 2000 is installed in a device, the first position corresponds to the closed position of the door body 3000, and the second position corresponds to the maximum opening angle position of the door body 3000. The damping device 270 can make the door body 3000 stay at a position less than the maximum opening angle, or the damping device 270 can make the door body 3000 stay at the maximum opening angle position.

[0076] When the hinge blade 220 starts to rotate from the first position under an external force (such as an elastic force), as the included angle between the hinge blade 220 and the hinge base 210 increases, the damping force generated by the damping device 270 can offset the external force or the inertial force when the hinge blade 220 rotates, so that the hinge blade 220 stays at the preset position.

[0077] For the hinge assembly 2000 according to an embodiment of the present invention, by providing the damping device 270 and sleeving the damping device 270 on the rotating shaft 250, the damping device 270 can offset the elastic force acting on the hinge blade 220 or the inertial force generated due to the hinge blade 220 being elastically opened, so that the hinge blade 220 can stop at the preset position. On the one hand, the controllability of the elastic opening position of the hinge blade 220 can be realized, and the impact force generated by the hinge blade 220 being elastically opened can be reduced, thereby reducing the noise generated during the automatic door opening process. On the other hand, if the automatically opened angle of the hinge blade 220 is less than the maximum angle, after the automatic door opening, it is convenient for the user to grasp the door body 3000 to realize manual door opening, especially for the scheme of embedding the door body 3000, the effect is more obvious.

[0078] As Figures 1 - 4 shown, according to some embodiments of the present invention, the hinge seat 210 is fixedly connected to the rotating shaft 250. The damping device 270 includes a first cam 274 and a second cam 275. One of the first cam 274 and the second cam 275 is sleeved on the rotating shaft 250 and can move along the axial direction of the rotating shaft 250. The other of the first cam 274 and the second cam 275 is fixed to the hinge blade 220 and can be rotationally engaged with the rotating shaft 250. The second cam 275 abuts against the first cam 274 to generate a damping force during the rotation of the hinge blade 220.

[0079] In the embodiment where the hinge seat 210 is fixedly connected to the rotating shaft 250, the first cam 274 moves along the axial direction of the rotating shaft 250, and the second cam 275 is fixedly connected to the hinge blade 220. Since the rotating shaft 250 and the hinge seat 210 are fixed and immovable, the first cam 274 will not perform a rotational movement. The first cam 274 can only move along the axial direction of the rotating shaft 250 relative to the rotating shaft 250.

[0080] When the hinge blade 220 starts to rotate from the first position, the hinge blade 220 can drive the second cam 275 to rotate together. The second cam 275 and the first cam 274 perform relative rotation, so that the damping force generated by the damping device 270 increases to offset the elastic force acting on the hinge blade 220 or the inertial force generated due to the hinge blade 220 being elastically opened, so that the hinge blade 220 can stop at a preset position.

[0081] As Figures 1 - 2 shown, in the embodiment where the hinge seat 210 is fixedly connected to the rotating shaft 250, the second cam 275 can move along the axial direction of the rotating shaft 250, and the first cam 274 is fixedly connected to the hinge blade 220. Since the rotating shaft 250 and the hinge seat 210 are fixed and immovable, and the rotating shaft 250 is engaged with the second cam 275, the second cam 275 will not perform a rotational movement. The second cam 275 can only move along the axial direction of the rotating shaft 250 relative to the rotating shaft 250.

[0082] When the hinge blade 220 starts to rotate from the first position, the hinge blade 220 can drive the first cam 274 to rotate together. The second cam 275 and the first cam 274 perform relative rotation, so that the acting force between the two increases, and the damping force generated by the damping device 270 increases to offset the elastic force acting on the hinge blade 220 or the inertial force generated due to the hinge blade 220 being elastically opened, so that the hinge blade 220 can stop at a preset position.

[0083] Accordingly, by setting the damping device 270 to include the first cam 274 and the second cam 275, the structure of the damping device 270 is made compact, the operation is reliable, and the control is more precise. When the hinge blade 220 rotates, relative rotation and movement can occur between the first cam 274 and the second cam 275, thereby changing the interaction force between the first cam 274 and the second cam 275, so that the damping device 270 generates a damping force. When the damping force reaches a value that can offset the elastic force acting on the hinge blade 220 or the inertial force generated due to the hinge blade 220 being elastically opened, the hinge blade 220 can stop at a preset position, and the controllability of the elastic opening position of the hinge blade 220 can be achieved.

[0084] In some embodiments, the second cam 275 and the side of the first cam 274 facing each other are respectively provided with a mating convex portion 276 and a mating concave portion 277. For example, the first cam 274 can be provided with the mating convex portion 276, and the second cam 275 can be provided with the mating concave portion 277; alternatively, the first cam 274 can be provided with the mating concave portion 277, and the second cam 275 can be provided with the mating convex portion 276.

[0085] As Figure 2 shown, in some specific embodiments, the mating concave portion 277 is an arc-shaped concave portion extending circumferentially along the rotation axis 250. The arc-shaped concave portion includes a first side wall 2771 and a second side wall 2772 that are oppositely arranged in its extending direction.

[0086] Among them, the hinge blade 220 is rotatable between a first position and a second position. In a state where the hinge blade 220 is in the first position, the mating convex portion 276 abuts against the first side wall 2771 of the arc-shaped concave portion. In a state where the hinge blade 220 is in the preset position, the mating convex portion 276 abuts against the second side wall 2772 of the arc-shaped concave portion. In a state where the hinge blade 220 is in the second position, the mating convex portion 276 is disengaged from the arc-shaped concave portion.

[0087] That is to say, the mating convex portion 276 can slide along the extending direction of the mating concave portion 277. When the mating convex portion 276 slides from the initial position (the position where the first side wall 27612711 is located) to the preset position, at this time the mating convex portion 276 abuts against the second side wall 2772, so that the second side wall 2772 can limit the mating convex portion 276, thereby preventing the hinge blade 220 from continuing to rotate and making the hinge blade 220 stop at the preset position.

[0088] In the above technical solution, by respectively providing the mating convex portion 276 and the mating concave portion 277 on the first cam 274 and the second cam 275, the controllability of the elastic opening position of the hinge blade 220 can be realized with a simple structure.

[0089] Among them, the numbers of the engaging convex portion 276 and the engaging concave portion 277 can be designed as required. For example, the first cam 274 can be provided with only one engaging convex portion 276, while the second cam 275 can be provided with one or more engaging concave portions 277; for another example, the first cam 274 can be provided with a plurality of engaging convex portions 276, and the second cam 275 can be provided with a plurality of engaging concave portions 277. Of course, the installation positions of the engaging convex portion 276 and the engaging concave portion 277 can also be interchanged.

[0090] In some embodiments, one of the first cam 274 and the second cam 275 is axially movable along the rotating shaft 250, and the damping device 270 further includes an elastic member 271 for pushing the second cam 275 to abut against the first cam 274.

[0091] By providing the elastic member 271, the elastic member 271 can store or release elastic potential energy according to the relative positions of the first cam 274 and the second cam 275, so as to change the acting force between the first cam 274 and the second cam 275, and can also keep the first cam 274 and the second cam 275 in a pressed state all the time, so that the damping device 270 can generate a damping force. In addition, the elastic member 271 can also reset one of the first cam 274 and the second cam 275, making it convenient to close the door.

[0092] Such as Figure 1 、 Figure 5 、 Figure 8 As shown, in some examples, the elastic member 271 is a spring sleeved on the rotating shaft 250 and abutting between one of the first cam 274 and the second cam 275 and the hinge blade 220.

[0093] Specifically, in the embodiment shown in Figures 1 - 10 the hinge seat 210 is fixedly connected to the rotating shaft 250, the second cam 275 is axially movable along the rotating shaft 250, and the first cam 274 is fixedly connected to the hinge blade 220 to rotate around the rotating shaft 250 with the hinge blade 220.

[0094] Hereinafter, an example will be given in which when the hinge blade 220 of the hinge assembly 2000 is in a preset position, the preset opening angle of the door body 3000 is less than the maximum opening angle.

[0095] Figure 1 、 Figure 3 and Figure 4 show a schematic diagram of the hinge blade 220 of the hinge assembly 2000 in the first position. In this position, the door body 3000 connected to the hinge blade 220 is in a closed state. Figures 5 - 7The schematic diagram shows the hinge vane 220 of the hinge assembly 2000 in a preset position. In this position, the door body 3000 connected to the hinge vane 220 is in a state of being opened by a preset angle. At this time, the included angle between the hinge vane 220 and the hinge seat 210 is α1.

[0096] Specifically, when the door body 3000 is bounced open, the door body 3000 drives the hinge vane 220 to rotate together. When the hinge vane 220 starts to rotate from the first position, the hinge vane 220 can drive the first cam 274 to rotate. Since the second cam 275 can only move relative to the rotating shaft 250 and the rotating shaft 250 is fixed, the first cam 274 can rotate along the extending direction of the mating recess 277. When the first cam 274 abuts against the second side wall 2772 of the mating recess 277, the second side wall 2772 can limit the mating protrusion 276, thereby preventing the hinge vane 220 from continuing to rotate and making the hinge vane 220 stay in the Figures 5 - 7 preset position as shown, so that the door body 3000 can stop in the set state.

[0097] Figures 8 - 10 The schematic diagram shows the hinge vane 220 of the hinge assembly 2000 in the second position. In this position, the door body 3000 connected to the hinge vane 220 is in a state of the maximum opening angle. At this time, the included angle between the hinge vane 220 and the hinge seat 210 is α2. Since the door body 3000 is opened by a certain angle, it is convenient for the user to grasp the door body 3000, so that the user can manually open the door. During the process of the user independently opening the door body 3000, the mating protrusion 276 and the mating recess 277 are gradually disengaged, and the first cam 274 drives the second cam 275 to move along the rotating shaft 250 in a direction away from the first cam 274, so that the length of the combined structure of the first cam 274 and the second cam 275 becomes longer, and the spring is gradually compressed, thereby storing elastic potential energy. At this time, the hinge vane 220 is in the Figures 8 - 10 second position as shown.

[0098] When closing the door, the second cam 275 moves in the direction close to the first cam 274 under the action of the spring, so that the length of the combined structure of the first cam 274 and the second cam 275 becomes shorter, and the spring gradually releases the elastic potential energy, so that the mating protrusion 276 and the mating recess 277 are mated again until the first cam 274 abuts against the first side wall 2771 of the mating recess 277 to realize the closing of the door body 3000.

[0099] Thus, by setting the elastic member 271 as a spring, the installation is more convenient and the structure can be made more compact.

[0100] As Figures 1 - 4As shown, in some examples, the rotating shaft 250 has a limiting portion 252, and the limiting portion 252 cooperates with one of the first cam 274 and the second cam 275 to prevent it from rotating relative to the rotating shaft 250.

[0101] In an embodiment where the hinge seat 210 is fixedly connected to the rotating shaft 250, the first cam 274 can move axially along the rotating shaft 250, and the second cam 275 is fixedly connected to the hinge blade 220. Since the rotating shaft 250 and the hinge seat 210 are fixed and immovable, the limiting portion 252 cooperates with the first cam 274 to limit the rotation of the first cam 274 on the rotating shaft 250. Therefore, the first cam 274 does not rotate, and the first cam 274 can only move axially along the rotating shaft 250 relative to the rotating shaft 250.

[0102] In an embodiment where the hinge seat 210 is fixedly connected to the rotating shaft 250, the second cam 275 can move axially along the rotating shaft 250, and the first cam 274 is fixedly connected to the hinge blade 220. Since the rotating shaft 250 and the hinge seat 210 are fixed and immovable, the limiting portion 252 cooperates with the second cam 275 to limit the rotation of the second cam 275 on the rotating shaft 250. Therefore, the second cam 275 does not rotate, and the second cam 275 can only move axially along the rotating shaft 250 relative to the rotating shaft 250.

[0103] Thus, by providing the limiting portion 252 on the rotating shaft 250, the rotation of one of the first cam 274 and the second cam 275 relative to the rotating shaft 250 can be restricted, so that during the rotation of the hinge blade 220, the relative positions of the first cam 274 and the second cam 275 in the axial direction of the rotating shaft 250 can be changed, which is beneficial to realizing the controllability of the elastic opening position of the hinge blade 220.

[0104] In some specific examples, the limiting portion 252 forms a section of the rotating shaft 250, and the cross-sectional shape of the limiting portion 252 is non-circular. The shape of the shaft hole of one of the first cam 274 and the second cam 275 is the same as the cross-sectional shape of the limiting portion 252. With such a setting, one of the first cam 274 and the second cam 275 can move axially along the rotating shaft 250.

[0105] For example, the cross-section of the limiting portion 252 can be square. Correspondingly, the shaft hole of one of the first cam 274 and the second cam 275 is a square hole; or, the cross-section of the limiting portion 252 can be oval. Correspondingly, the shaft hole of one of the first cam 274 and the second cam 275 is an oval shaft hole; or, the cross-section of the limiting portion 252 can be irregular. Correspondingly, the shaft hole of one of the first cam 274 and the second cam 275 is an irregular hole.

[0106] Among them, the shaft hole of the other one of the first cam 274 and the second cam 275 is a circular hole, so that the other one of the first cam 274 and the second cam 275 can rotate relative to the rotating shaft 250.

[0107] As Figure 4 shown, according to some embodiments of the present invention, the rotating shaft 250 is fixedly connected to the hinge seat 210. The hinge blade 220 includes a first connecting portion 2261 and a second connecting portion 2262. The first connecting portion 2261 and the second connecting portion 2262 are arranged at an axial interval of the rotating shaft 250, and both the first connecting portion 2261 and the second connecting portion 2262 are rotationally matched with the rotating shaft 250, so that the rotational connection between the hinge blade 220 and the hinge seat 210 can be realized.

[0108] Among them, the damping device 270 is arranged between the first connecting portion 2261 and the second connecting portion 2262, so that the damping device 270 is sleeved on the rotating shaft 250, and the damping device 270 can be connected to the hinge seat 210 through the rotating shaft 250. Since the damping device 270 is located between the first connecting portion 2261 and the second connecting portion, it is convenient to connect part of the structure of the damping device 270 to the hinge blade 220 through the first connecting portion 2261 or the second connecting portion 2262, so that the damping device 270 is connected to the hinge seat 210 and the hinge blade 220.

[0109] Thus, by arranging the hinge blade 220 to include the first connecting portion 2261 and the second connecting portion 2262 arranged at an interval, on the one hand, the hinge blade 220 can be rotationally matched with the rotating shaft 250, and on the other hand, an installation space for the damping device 270 can be formed between the first connecting portion 2261 and the second connecting portion 2262, improving the space utilization rate. It is also convenient to connect part of the structure of the damping device 270 to the hinge blade 220 through the first connecting portion 2261 or the second connecting portion 2262, so that the damping device 270 is connected to the hinge seat 210 and the hinge blade 220.

[0110] In some embodiments not shown in the figure, the rotating shaft 250 is fixedly connected to the hinge seat 210. The hinge blade 220 includes a third connecting portion (not shown in the figure), the third connecting portion is rotationally matched with the rotating shaft 250, and the damping device 270 is arranged between the third connecting portion and the hinge seat 210.

[0111] With such an arrangement, the elastic member 271 of the damping device 270 can directly act on the hinge seat 210, simplifying the force transmission path, and the structure of the hinge blade 220 can also be simplified. When assembling the damping device 270, the hinge seat 210 and the hinge blade 220, the rotating shaft 250 can be sequentially passed through a part of the hinge seat 210, the hinge blade 220, the damping device 270, and another part of the hinge seat 210, and the assembly steps are simpler.

[0112] As Figures 1 - 10 shown, according to some embodiments of the present invention, the hinge blade 220 includes a first connection section 223, a second connection section 224, and a transition section 225. One end of the first connection section 223 is rotatably connected to the hinge seat 210 through a rotating shaft 250. The second connection section 224 is disposed on one side in the thickness direction of the first connection section 223. Both ends of the transition section 225 are respectively connected to the other end of the first connection section 223 and one end of the second connection section 224, and at least a part of the transition section 225 penetrates through the opening 214.

[0113] Further, the damping device 270 cooperates with the first connection section 223 to generate damping for the hinge blade 220, preventing the damping device 270 from entering the rotation angle range of the hinge blade 220 and interfering with the hinge blade 220 to affect the rotation of the hinge blade 220.

[0114] Among them, by connecting one end of the first connection section 223 to the hinge seat 210 through the rotating shaft 250, the rotational connection between the hinge blade 220 and the hinge seat 210 can be realized; by passing the transition section 225 through the opening 214, the fixed connection between the hinge blade 220 and the door body 3000 can be realized; by connecting both ends of the transition section 225 to the other end of the first connection section 223 and one end of the second connection section 224 respectively, the fixed connection between the first connection section 223 and the second connection section 224 can be realized.

[0115] In some embodiments, the rotating shaft 250 is fixed to the hinge seat 210. The first connection section 223 of the hinge blade 220 includes a first connection portion 2261 and a second connection portion 2262. The first connection portion 2261 and the second connection portion 2262 are arranged at intervals in the axial direction of the rotating shaft 250. Both the first connection portion 2261 and the second connection portion 2262 are rotationally matched with the rotating shaft 250, so that the rotational connection between the hinge blade 220 and the hinge seat 210 can be realized.

[0116] Of course, the rotating shaft 250 can also be fixed to the hinge blade 220, and the rotating shaft 250 is rotationally connected to the hinge seat 210, so that the rotational connection between the hinge blade 220 and the hinge seat 210 can be realized.

[0117] As Figure 3 and Figure 4 、 Figure 6 and Figure 7 、 Figure 9 and Figure 10 shown, in some embodiments, the transition section 225 forms an arc structure, and the radial direction of the arc structure intersects with the rotation axis of the rotating shaft 250. For example, the center of the arc structure can be located on the rotation axis of the rotating shaft 250, and the second connection section 224 is a straight structure.

[0118] Among them, by forming the transition section 225 into an arc structure, when the hinge blade 220 rotates around the rotating shaft 250, the contact between the hinge blade 220 and the hole wall of the opening 214 can be avoided to a certain extent, so that the hinge blade 220 can rotate effectively, and the stability during the rotation process can be ensured to a certain extent, that is, the stability of the door body 3000 during the rotation process can be ensured to a certain extent, and the working performance of the door body 3000 is ensured.

[0119] At the same time, by setting the second connecting section 224 as a straight structure, the forming difficulty of the second connecting section 224 can be reduced, and the connecting difficulty between the second connecting section 224 and the door body 3000 can also be reduced.

[0120] In some embodiments, the first connecting section 223 forms an arc structure bent in a direction away from the second connecting section 224, so that the first connecting section 223 can be avoided from being interfered during the rotation of the hinge blade 220 to a certain extent, so that the hinge blade 220 can rotate effectively, and the stability during the rotation process can be ensured to a certain extent.

[0121] Of course, the first connecting section 223 can also form a straight structure, that is, both ends of the arc transition section 225 are respectively connected to one end of the first connecting section 223 and one end of the second connecting section 224, so that the hinge blade 220 can form a multi-bending structure.

[0122] In order to match modern furniture, the current laundry treatment device is increasingly inclined to be fully embedded or flush-mounted in the cabinet body. However, this installation method will affect the opening angle of the door body. Based on this, the present application provides a laundry treatment device 6000, which by adopting the above hinge assembly 2000, can make the door body 3000 open to the maximum opening angle on the basis of ensuring that the laundry treatment device can be fully embedded or flush-mounted in the cabinet body, and after opening the door body 3000, the hinge seat 210 cannot be seen, and the aesthetics is higher.

[0123] The laundry treatment device 6000 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0124] As Figures 11 - 15 shown, the laundry treatment device 6000 according to an embodiment of the present invention includes a cabinet assembly 1000 and a door body 3000. The cabinet assembly 1000 has a through opening 110, and the door body 3000 is rotatably arranged outside the cabinet assembly 1000 through a hinge assembly 2000. The door body 3000 is used to open and close the through opening 110, and the hinge assembly 2000 is the hinge assembly 2000 according to the above embodiment.

[0125] The laundry treating apparatus 6000 further includes an automatic door opening assembly configured to open the door body 3000 by a preset angle after the laundry treating program of the laundry treating apparatus 6000 ends, where the preset angle is less than or equal to the maximum door opening angle.

[0126] Among them, the hinge seat 210 of the hinge assembly 2000 is disposed inside the cabinet assembly 1000, and the hinge seat 210 is connected to the cabinet assembly 1000. The door body 3000 is connected to the hinge blade 220, hiding the hinge seat 210 inside the cabinet assembly 1000. When the door body 3000 is opened, the hinge seat 210 will not be seen, which is beneficial to improving the visual experience of the laundry treating apparatus 6000.

[0127] Since the hinge assembly 2000 according to the embodiment of the present invention has the above technical effects, the laundry treating apparatus 6000 according to the embodiment of the present invention also has the above technical effects, that is, by adopting the above hinge assembly 2000, the door body 3000 can be stopped in the state of being opened by a preset angle. On the one hand, the controllability of the popping-open position of the door body 3000 can be realized, reducing the impact force generated when the door body 3000 is popped open, thereby reducing the noise generated during the door opening process. On the other hand, after the door body 3000 is opened by a certain angle, it is convenient for the user to grasp the door body 3000 to achieve automatic door opening, especially for the scheme where the door body 3000 is embedded, the effect is more obvious.

[0128] In addition, by setting the automatic door opening assembly, on the one hand, after the laundry treating program of the laundry treating apparatus 6000 is executed and ends, the door body 3000 can be automatically opened without the user manually opening the door. On the other hand, it can remind the user to take out the clothes in time. And even if the user does not take out the clothes in time, since the door body 3000 has opened the through-opening 110, natural wind can be introduced into the laundry treating cavity to avoid the clothes from generating peculiar smell due to being not taken out for a long time; by disposing the hinge seat 210 inside the cabinet assembly 1000, when the door body 3000 is opened, the hinge seat 210 will not be seen, which is beneficial to improving the visual experience of the laundry treating apparatus 6000.

[0129] As Figure 14 shown, according to some embodiments of the present invention, the cabinet assembly 1000 includes a mounting panel 102, the through-opening 110 is disposed on the mounting panel 102, the door body 3000 is rotatably disposed outside the mounting panel 102 through the hinge assembly 2000, the door body 3000 is used to open and close the through-opening 110, and the hinge assembly 2000 is disposed inside the mounting panel 102. Here, the mounting panel 102 may be the front panel of the laundry treating apparatus 6000.

[0130] As Figures 11 - 13As shown, the cabinet assembly 1000 further includes a cabinet 101. One side of the cabinet 101 has an opening, and an installation panel 102 is provided at the opening and connected to the cabinet 101, so that the installation panel 102 and the cabinet 101 are combined to form a relatively sealed cabinet assembly 1000, thereby protecting the important structures of the laundry treatment device 6000.

[0131] As Figure 14 shown, according to some embodiments of the present invention, the installation panel 102 further has an avoidance opening 120. The avoidance opening 120 is located on one side of the through opening 110, and the avoidance opening 120 is disposed opposite to the opening 214. It should be noted that the so-called one side here can be any side in the circumferential direction of the through opening 110, such as: the left side, the right side, the upper side, the lower side, or the upper left side, the lower left side, etc.

[0132] Among them, the hinge seat 210 is provided on the inner side of the installation panel 102, and at least a part of the hinge blade 220 extends to the outside of the installation panel 102 through the avoidance opening 120 to be connected to the door body 3000.

[0133] In some embodiments, both the through opening 110 and the avoidance opening 120 can penetrate the installation panel 102 in the thickness direction of the installation panel 102. Among them, by providing the through opening 110, the communication between the opposite sides in the thickness direction of the installation panel 102 is realized; by providing the avoidance opening 120, it is ensured that when the hinge seat 210 is provided on the inner side of the installation panel 102 and the hinge blade 220 is rotatably connected to the hinge seat 210, a part of the hinge blade 220 can extend to the outside of the installation panel 102 through the avoidance opening 120 to be connected to the door body 3000.

[0134] The door body 3000 is rotatably provided on the outside of the installation panel 102 through the hinge assembly 2000, and the door body 3000 is used to open and close the through opening 110. That is to say, the hinge assembly 2000 can rotatably arrange the door body 3000 on the outside of the installation panel 102, so as to facilitate using the door body 3000 to open and close the through opening 110 on the installation panel 102. Among them, when the through opening 110 is opened by using the door body 3000, the communication between the opposite sides of the installation panel 102 can be realized; when the through opening 110 is closed by using the door body 3000, the through opening 110 can be blocked.

[0135] In some embodiments, the size of the door body 3000 is greater than or equal to the size of the through opening 110. For example, the shape of the door body 3000 is adapted to the shape of the through opening 110, so as to facilitate using the door body 3000 to open and close the through opening 110 and ensure the shielding effect when the door body 3000 closes the through opening 110 to a certain extent.

[0136] It should also be noted that the above-mentioned door body 3000 can be a circular door body 3000, a square door body 3000 (such as a rectangular door body 3000, a square door body 3000, etc.), or other irregular-shaped door bodies 3000. Among them, when the door body 3000 is a circular door body 3000, the door body 3000 and the box body assembly 1000 can be rotatably connected through a hinge assembly 2000, and the hinge assembly 2000 can be arranged on any side of the circular door body 3000; when the door body 3000 is a square door body 3000, the door body 3000 and the box body assembly 1000 can be rotatably connected through a hinge assembly 2000, or can be rotatably connected through multiple hinge assemblies 2000. When multiple hinge assemblies 2000 are provided, a plurality of avoidance openings 120 are provided on the mounting panel 102, and the plurality of avoidance openings 120 correspond to the plurality of hinge assemblies 2000 one by one, and the plurality of hinge assemblies 2000 are spaced on the same side of the square door body 3000. In this way, while using the hinge assembly 2000 to realize the rotational connection between the door body 3000 and the mounting panel 102, the connection strength between the door body 3000 and the mounting panel 102 can also be improved, thereby ensuring the stability of the door body 3000 during rotation to a certain extent.

[0137] It should be emphasized that in the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0138] In this embodiment, the hinge seat 210 and the door body 3000 are arranged on opposite sides of the mounting panel 102, and the hinge blade 220 can be connected to the hinge seat 210 and the door body 3000 located on opposite sides of the mounting panel 102 at the same time.

[0139] Among them, by arranging the hinge seat 210 and the door body 3000 on the inner and outer sides of the mounting panel 102, when the door body 3000 opens the through opening 110, the mounting panel 102 can be used to block the hinge seat 210, so as to avoid the user directly observing the hinge seat 210 to a certain extent, thereby improving the aesthetics of the laundry treatment device 6000, and the mounting panel 102 can also be used to protect the hinge seat 210 and extend the service life of the hinge seat 210.

[0140] It should be noted that the above-mentioned outer side can be understood as Figure 14 the front side of the mounting panel 102 shown, and the inner side can be understood as Figure 14 the rear side of the mounting panel 102 shown, and the inner side and the outer side are oppositely arranged.

[0141] Of course, in some other embodiments, when the door body 3000 is located at the top of the box body assembly 1000, the above-mentioned outer side can be understood as the upper side of the mounting panel 102, and the inner side can be understood as the lower side of the mounting panel 102, and the upper side and the lower side are oppositely arranged.

[0142] By rotatably connecting the hinge blade 220 to the hinge seat 210 and extending at least a part of the hinge blade 220 to the outside of the mounting panel 102 through the avoidance opening 120 to connect with the door body 3000, the rotational connection between the door body 3000 and the mounting panel 102 is realized, facilitating the control of the rotation of the door body 3000 relative to the mounting panel 102 to realize the opening and closing of the through opening 110 by the door body 3000, and reducing the difficulty of opening and closing the through opening 110.

[0143] As can be seen from the above structure, by providing the avoidance opening 120 on the mounting panel 102, a part of the hinge assembly 2000 can be arranged inside the mounting panel 102 and another part of the hinge assembly 2000 can be arranged outside the mounting panel 102 to connect with the door body 3000, thereby realizing the rotational connection between the mounting panel 102 and the door body 3000. While ensuring the opening and closing performance of the door body 3000, the appearance of the laundry treatment device 6000 can be improved, and the aesthetic degree of the laundry treatment device 6000 can be enhanced.

[0144] In some embodiments, as shown in Figure 1 、 Figure 5 and Figure 8 , a first connection hole 213 is provided on the hinge seat 210, and a first mating hole matching with the first connection hole 213 is provided on the mounting panel 102. The first connection hole 213 and the first mating hole are fixedly connected by a first fastener, thereby realizing the fixed connection between the hinge seat 210 and the mounting panel 102, facilitating the use of the mounting panel 102 to support the hinge seat 210, and improving the position stability of the hinge seat 210.

[0145] Optionally, the first fastener is a fastening bolt or a fastening screw, etc. In this way, while realizing the fixed connection between the hinge seat 210 and the mounting panel 102 by the first fastener, the hinge seat 210 and the mounting panel 102 can be detachably connected, so as to reduce the connection difficulty between the hinge seat 210 and the mounting panel 102 and improve the connection efficiency.

[0146] Of course, in some other embodiments, the hinge seat 210 and the mounting panel 102 can also be non-detachably connected by bonding, welding, etc., and no specific limitation is made here.

[0147] As shown in Figure 1 、 Figure 5 、 Figure 8 , in some embodiments, the hinge seat 210 includes a first seat body 215 and a second seat body 216. The second seat body 216 is connected to one end of the first seat body 215. The rotating shaft 250 is arranged on the second seat body 216 to rotatably connect the hinge blade 220 with the second seat body 216, and an opening 214 is arranged on the second seat body 216.

[0148] Here, it means that the hinge base 210 includes a first base body 215 and a second base body 216 which are connected to each other. The hinge blade 220 is rotatably connected to the second base body 216. In this way, while realizing the rotational connection between the hinge blade 220 and the hinge base 210, the connection difficulty between the hinge blade 220 and the hinge base 210 can be reduced.

[0149] Meanwhile, by providing an opening 214 on the second base body 216 and setting the opening 214 opposite to and communicating with the avoidance opening 120, while ensuring that at least a part of the hinge blade 220 connected to the second base body 216 can extend through the avoidance opening 120 to be connected to the door body 3000, it can also avoid the second base body 216 from hindering the rotation of the hinge blade 220 to a certain extent, that is, to avoid the interference of the hinge blade 220 with the hinge base 210 during the rotation process, thereby ensuring the smooth rotation of the hinge blade 220 to a certain extent and improving the working performance of the hinge assembly 2000.

[0150] Optionally, as Figure 14 shown, one end of the first base body 215 away from the second base body 216 is connected to the mounting panel 102, and one end of the second base body 216 away from the hinge blade 220 is connected to the mounting panel 102. That is to say, both the first base body 215 and the second base body 216 are connected to the mounting panel 102. In this way, while realizing the fixed connection between the hinge base 210 and the mounting panel 102, the connection strength between the hinge base 210 and the mounting panel 102 can also be improved, so as to facilitate the use of the mounting panel 102 to support the hinge base 210 and improve the position stability of the hinge base 210, that is, to improve the position stability of the hinge assembly 2000, and ensure the working performance of the hinge assembly 2000 to a certain extent.

[0151] In addition, through the above settings, the connection points of the first base body 215, the second base body 216 and the mounting panel 102 can be set far away from the hinge blade 220, so as to avoid the hinge blade 220 from hindering the connection between the hinge base 210 and the mounting panel 102, thereby reducing the connection difficulty between the hinge base 210 and the mounting panel 102.

[0152] In some embodiments, as shown in combination with Figure 1 、 Figure 5 and Figure 8 shown, first connection holes 213 are provided on one end of the first base body 215 away from the second base body 216 and one end of the second base body 216 away from the hinge blade 220. The first base body 215 and the second base body 216 are respectively fixedly connected to the mounting panel 102 through the first connection holes 213 to realize the fixed connection between the hinge base 210 and the mounting panel 102.

[0153] In summary, the hinge seat 210 of the present application includes a first seat body 215 and a second seat body 216 that are connected to each other. The first seat body 215 is used to realize the fixed connection between the hinge seat 210 and the mounting panel 102, and the second seat body 216 is used to realize the rotational connection between the hinge seat 210 and the hinge blade 220 and the fixed connection between the hinge seat 210 and the mounting panel 102 to ensure the working performance of the hinge seat 210.

[0154] In some examples, the mounting panel 102 includes a panel body 140. The panel body 140 includes a main panel 142 and side plates 141, and the side plates 141 are provided on the sides of the main panel 142.

[0155] The mounting panel 102 further includes a mounting portion 150 and a connecting flange 160. The mounting portion 150 is connected to the main panel 142, and the mounting portion 150 defines a through port 110. An avoidance port 120 is provided on the mounting portion 150. The connecting flange 160 is connected to the side plate 141, and the connecting flange 160 is disposed opposite to the main panel 142. The first seat body 215 is connected to the side of the connecting flange 160 facing away from the main panel 142, and the second seat body 216 is connected to the mounting portion 150.

[0156] That is to say, the mounting panel 102 includes a main panel 142, side plates 141, a mounting portion 150, and a connecting flange 160. Among them, both the main panel 142 and the connecting flange 160 are connected to the side plate 141 and are disposed opposite to each other. The first seat body 215 is connected to the side of the connecting flange 160 facing away from the main panel 142, thereby realizing the fixed connection between the first seat body 215 and the mounting panel 102. The mounting portion 150 is connected to the main panel 142 and the second seat body 216 is connected to the mounting portion 150, thereby realizing the fixed connection between the second seat body 216 and the mounting panel 102, enabling the hinge seat 210 to be stably connected to the mounting panel 102 and improving the position stability of the hinge seat 210.

[0157] At the same time, since an avoidance port 120 is provided on the mounting portion 150, after connecting the mounting portion 150 to the main panel 142, the through port 110 and the avoidance port 120 can be defined, thereby realizing the formation of the through port 110 and the avoidance port 120 on the mounting panel 102.

[0158] In some embodiments, as Figure 14 shown, the mounting portion 150 is provided on the inner circumferential side of the panel body 140, and the mounting portion 150 is formed as an annular structure to define a through port 110.

[0159] It should be noted that the installation part 150 mentioned here refers to the installation part 150 for installing the door body 3000. In a specific example, the installation part 150 is a region formed by the main panel 142 recessing backward. The bottom wall of the recessed region is formed with the above-mentioned through opening 110, and the side wall of the recessed region is formed with the above-mentioned avoidance opening 120, so as to form the through opening 110 and the avoidance opening 120 on the installation panel 102.

[0160] It should also be noted that by connecting the first seat body 215 to the side of the connecting flange 160 facing away from the main panel 142, the connection between the first seat body 215 and the outer side of the connecting flange 160 can be realized. On the one hand, the connection difficulty between the first seat body 215 and the connecting flange 160 can be reduced; on the other hand, when the first seat body 215 is arranged on the main panel 142 in the prior art, the wear of the main panel 142 can be reduced.

[0161] In some embodiments, as Figure 14 shown, at least part of the connecting flange 160 protrudes towards the main panel 142 to form an insertion opening 161 on the side of the connecting flange 160 facing away from the main panel 142. The first seat body 215 is provided with an insertion plate 2151 that is inserted and matched with the insertion opening 161. The insertion plate 2151 cooperates with the insertion opening 161. In this way, while realizing the connection between the first seat body 215 and the connecting flange 160, the first seat body 215 can also form an insertion fit with the installation panel 102, so as to reduce the connection difficulty between the hinge seat 210 and the installation panel 102, and at the same time improve the connection strength between the hinge seat 210 and the installation panel 102, and further improve the position stability of the hinge seat 210.

[0162] In some embodiments, as Figure 1 、 Figure 5 and Figure 8 shown, the insertion plate 2151 is provided with a first connection hole 213. In this way, during the connection process of the hinge seat 210 and the installation panel 102, the insertion plate 2151 can be first inserted and matched in the insertion opening 161 to realize the preliminary positioning of the hinge seat 210, and then the hinge seat 210 and the installation panel 102 are connected by the first fastener to realize the fixed connection between the hinge seat 210 and the installation panel 102, reducing the connection difficulty between the hinge seat 210 and the installation panel 102.

[0163] As Figure 1 、 Figure 5 and Figure 8As shown, in some embodiments, the second seat body 216 includes a first extension section 2161 and a second extension section 2162. One end of the second extension section 2162 is connected to one end of the first extension section 2161, and the hinge blade 220 is connected to the end of the second extension section 2162 away from the first extension section 2161. That is to say, the second seat body 216 includes the first extension section 2161 and the second extension section 2162 that are connected to each other, and the hinge blade 220 is connected to the end of the second extension section 2162 away from the first extension section 2161 to realize the connection of the hinge blade 220 to the hinge seat 210.

[0164] Optionally, one end of the first extension section 2161 away from the second extension section 2162 is connected to the mounting panel 102. It can be understood here that the two ends of the first extension section 2161 and the second extension section 2162 away from each other are respectively connected to the mounting panel 102 and the hinge blade 220. In this way, while realizing the fixed connection between the hinge seat 210 and the mounting panel 102 and realizing the rotational connection between the hinge seat 210 and the hinge blade 220, it can also avoid the interference between the hinge blade 220 and the mounting panel 102 during the assembly process of the hinge seat 210, so as to reduce the assembly difficulty of the hinge assembly 2000.

[0165] Combined with Figure 14 , the mounting portion 150 includes a first area 151 and a second area 152. The second area 152 is connected between the panel body 140 and the first area 151 and is inclined with respect to the panel body 140 and the first area 151. The avoidance opening 120 is provided in the second area 152. Among them, by connecting the second area 152 between the panel body 140 and the first area 151, the fixed connection between the panel body 140 and the first area 151 is realized, so that the relative positions of the panel body 140 and the first area 151 are stable, thereby ensuring the structural stability of the mounting panel 102.

[0166] At the same time, by setting the second area 152 to be inclined with respect to the panel body 140 and the first area 151 and providing the avoidance opening 120 in the second area 152, while ensuring that at least a part of the hinge blade 220 can extend to one side of the hinge seat 210 to be connected to the door body 3000, it can also avoid the interference between the hinge blade 220 and the second area 152 when the hinge blade 220 rotates relative to the avoidance opening 120, ensuring the smooth rotation of the hinge blade 220.

[0167] In a specific example, such as Figure 14As shown, the second region 152 is connected to one end of the main panel 142 away from the side panel 141 and is inclined relative to the main panel 142 and the first region 151, so as to facilitate forming the mounting portion 150 on the panel body 140 and make at least part of the mounting portion 150 inclined relative to the panel body 140, which is convenient for arranging an avoidance opening 120 for avoiding the rotation of the hinge blade 220 on the mounting portion 150.

[0168] In some embodiments, the door body 3000 is arranged on the front side of the mounting panel 102, the first region 151 is arranged on the rear side of the main panel 142, and the second region 152 is connected between the main panel 142 and the first region 151 and is inclined backward in the direction of the through opening 110, so as to further prevent the hinge blade 220 from interfering with the second region 152 during rotation and ensure the smooth rotation of the hinge blade 220.

[0169] In the description of the present invention, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features, which are used to distinguish and describe the features, without order or importance.

[0170] In some embodiments, in combination Figure 1 、 Figure 5 and Figure 8 As shown, a second connection hole 2242 is provided on a part of the hinge blade 220 extending to the outside of the mounting panel 102, a second mating hole (not shown in the figure) matching the second connection hole 2242 is arranged on the door body 3000, and the second connection hole 2242 and the second mating hole are fixedly connected by a second fastener, so as to realize the fixed connection between the hinge blade 220 and the door body 3000, which is convenient for using the hinge blade 220 to realize the rotational connection between the door body 3000 and the mounting panel 102, thereby ensuring the working performance of the door body 3000 to a certain extent.

[0171] Optionally, the second fastener is a fastening bolt or a fastening screw, etc. In this way, while using the second fastener to realize the fixed connection between the hinge blade 220 and the door body 3000, the hinge blade 220 and the door body 3000 can also form a detachable connection, so as to reduce the connection difficulty between the hinge blade 220 and the door body 3000 and improve the connection efficiency.

[0172] Of course, in some other embodiments, the hinge blade 220 and the door body 3000 can also be non-detachably connected by bonding, welding, etc., which is not specifically limited herein.

[0173] In some embodiments, in combination Figure 1 、 Figure 5 and Figure 8As shown, a positioning convex portion 2241 is further provided on a part of the hinge blade 220 extending to the outside of the mounting panel 102. A positioning hole (not shown in the figure) that cooperates with the positioning convex portion 2241 is provided on the door body 3000. The positioning convex portion 2241 is cooperatively connected in the positioning hole to achieve the positioning cooperation between the hinge blade 220 and the door body 3000, thereby reducing the connection difficulty between the hinge blade 220 and the door body 3000.

[0174] With the above arrangement, in a specific example, when the hinge blade 220 is connected to the door body 3000, the initial positioning between the hinge blade 220 and the door body 3000 can be first achieved by the cooperation of the positioning convex portion 2241 and the positioning hole, making the relative position between the hinge blade 220 and the door body 3000 stable. Subsequently, the second fastener is used to achieve the fixed connection between the hinge blade 220 and the door body 3000. In this way, while ensuring the connection strength between the hinge blade 220 and the door body 3000, the connection difficulty between the hinge blade 220 and the door body 3000 can also be reduced.

[0175] In some embodiments, one end of the rotating shaft 250 is provided with an external thread, and the hinge seat 210 is provided with an internal thread that cooperates with the external thread. The external thread and the internal thread are cooperatively connected to connect the rotating shaft 250 to the hinge seat 210, thereby facilitating the rotational connection between the hinge blade 220 and the hinge seat 210 by using the rotating shaft 250.

[0176] As Figures 11 - 14 shown, according to some embodiments of the present invention, the automatic door opening assembly includes a door lock and a door hook. One of the door lock 310 and the door hook 320 is provided on the cabinet assembly 1000 and the other is provided on the door body 3000. The door lock 310 switches between a state of locking the door hook 320 and a state of unlocking the door hook.

[0177] As Figure 15 shown, the automatic door opening assembly further includes a jacking member 330. The jacking member 330 is provided on one of the cabinet assembly 1000 and the door body 3000 and is used to jack open the door body 3000 when the door lock 310 unlocks the door hook 320.

[0178] Specifically, Figure 11 shows a schematic structural diagram of the laundry treatment device 6000 when the door body 3000 is in a closed state. Figure 12 shows a schematic structural diagram of the laundry treatment device 6000 when the door body 3000 is in a state of being opened at a preset angle. Figure 13 shows a schematic structural diagram of the laundry treatment device 6000 when the door body 3000 is in a state of being opened at the maximum opening angle.

[0179] Among them, as Figure 15As shown, a top-opening component 330 is provided on one side of the door body 3000 facing the cabinet assembly 1000. The top-opening component 330 is used to push open the door body 3000 when the door lock 310 and the door hook 320 are disengaged after the clothing treatment program of the clothing treatment device 6000 ends.

[0180] Specifically, the top-opening component 330 includes a reset member 332 and a ejector rod 331. The ejector rod 331 is movable along the thickness direction of the door body 3000. The reset member 332 is connected to the door body 3000 and the ejector rod 331, and is used to drive the ejector rod 331 to move towards a position extending out of the door body 3000.

[0181] As Figure 11 shown, when the door body 3000 of the clothing treatment device 6000 is in the closed state, the top-opening component 330 is compressed and stores energy, and the door hook 320 on the door body 3000 is locked by the door lock 310 on the cabinet assembly 1000.

[0182] As Figure 12 shown, when the clothing treatment device 6000 executes an opening door command, the door lock 310 is unlocked, the door hook 320 is released, and the top-opening component 330 releases elastic force to push open the door body 3000. When the door body 3000 drives the hinge blade 220 to rotate a certain angle from the first position, the damping force generated by the damping device 270 can offset the elastic opening force or the inertial force generated due to the door body 3000 being elastically opened, so that the door body 3000 stops at the set state. At this time, the hinge blade 220 is in the preset position.

[0183] Since Figure 12 the door body 3000 in Figure 13 opens a certain angle, it is convenient for the user to grasp the door body 3000, so that the user can manually open the door. During the process of the user opening the door body 3000, the damping force of the damping device 270 gradually decreases at least within a certain angle range and even drops to zero, so that the user can smoothly open the door body 3000 to the preset angle or even fully open it. When the door body 3000 is in
