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

[0071] Below, refer to Figures 1 - 9 Describe the hinge assembly 2000 according to the embodiments of the present invention.

[0072] AsFigures 1 - 9 As 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 disposed on the hinge base 210 through the rotating shaft 250.

[0073] Moreover, at least a part of the hinge blade 220 passes through the opening 214. With this arrangement, 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. Both ends of the damping device 270 are respectively connected to the hinge base 210 and the hinge blade 220, and are 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 located 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 the action of 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 gradually increases at least within a certain angular range. When the damping force of the damping device increases to just cancel the external force or the inertial force when the hinge blade 220 rotates, the hinge blade 220 can be made to stay at the preset position.

[0077] According to the hinge assembly 2000 of an embodiment of the present invention, by providing a damping device 270 and connecting both ends of the damping device 270 to a hinge base 210 and a hinge vane 220, the damping device 270 can be used to offset the elastic force acting on the hinge vane 220 or the inertial force generated due to the hinge vane 220 being elastically opened, so that the hinge vane 220 can stop at a preset position. On the one hand, the controllability of the elastic opening position of the hinge vane 220 can be achieved, and the impact force generated due to the hinge vane 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 vane 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 achieve manual door opening, especially for the scheme of embedding the door body 3000, the effect is more obvious.

[0078] As Figures 1 - 3 shown, according to some embodiments of the present invention, the damping device 270 includes an elastic member 271. The elastic member 271 is located between the hinge base 210 and the hinge vane 220 and is used to provide a damping force.

[0079] For example, both ends of the elastic member 271 can be respectively connected to or in abutting cooperation with the hinge base 210 and the hinge vane 220. When the hinge vane 220 starts to rotate from a first position under an external force (such as an elastic force), the elastic member 271 continuously stores elastic potential energy. As the included angle between the hinge vane 220 and the hinge base 210 increases, the elastic potential energy stored in the elastic member 271 gradually increases at least within a certain angular range. When the elastic potential energy stored in the elastic member 271 increases to just offset the external force or the inertial force during the rotation of the hinge vane 220, the hinge vane 220 can be stopped at a preset position.

[0080] When the hinge vane 220 rotates from the preset position to a second position, the elastic member 271 can gradually return to its initial state, thereby releasing the stored elastic potential energy to reduce the resistance of the user's manual door opening.

[0081] Thus, by setting the damping device 270 to include the elastic member 271, the elastic member 271 can undergo elastic deformation, thereby storing and releasing elastic potential energy, so as to use the elastic member 271 to provide a certain resistance for the hinge vane 220 within a certain angular range of rotation, achieving the controllability of the elastic opening position of the hinge vane 220 and reducing the impact force generated due to the hinge vane 220 being elastically opened.

[0082] In some embodiments, the elastic member 271 is a spring. The damping device 270 further includes a guide sleeve 272 and a guide rod 273. At least a part of the guide rod 273 is disposed within the guide sleeve 272. The spring is at least partially disposed within the guide sleeve 272 and sleeved on the guide rod 273. One of the hinge seat 210 and the hinge blade 220 is rotatably connected to the guide sleeve 272, and the other of the hinge seat 210 and the hinge blade 220 is rotatably connected to the guide rod 273.

[0083] During the rotation of the hinge blade 220, the axial directions of the guide sleeve 272 and the guide rod 273 change relative to the hinge seat 210 and the hinge blade 220, and relative movement occurs between the guide sleeve 272 and the guide rod 273. The spring can be compressed or stretched, so that elastic potential energy can be stored and released, and the damping device 270 can be used to provide a certain resistance for the hinge blade 220 within a certain rotation angle range, realizing the controllability of the elastic opening position of the hinge blade 220 and reducing the impact force generated when the hinge blade 220 is elastically opened.

[0084] Hereinafter, an example will be given in which when the hinge blade 220 is in a preset position, the preset opening angle of the door body 3000 is smaller than the maximum opening angle.

[0085] Figures 1 - 3 A schematic diagram showing the hinge blade 220 of the hinge assembly 2000 in the first position is shown. In this position, the door body 3000 connected to the hinge blade 220 is in a closed state. Figures 4 - 6 A schematic diagram showing the hinge blade 220 of the hinge assembly 2000 in a preset position is shown. In this position, the door body 3000 connected to the hinge blade 220 is in a state of opening a preset angle. Specifically, when the door body 3000 is elastically opened, the door body 3000 drives the hinge blade 220 to rotate together. When the hinge blade 220 starts to rotate from the first position, the length of the damping device 270 gradually decreases, and the guide rod 273 moves towards the inside of the guide sleeve 272. Subsequently, the spring is gradually compressed, so that elastic potential energy can be stored, so that the damping device 270 generates a damping force. When the damping force of the damping device 270 increases to be able to offset the elastic opening force or the inertial force generated due to the elastic opening of the door body 3000, the hinge blade 220 stops at the Figures 4 - 6 preset position shown, so that the door body 3000 can stop at the set state.

[0086] Figures 7 - 9The 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 the state of the maximum opening angle. Since the door body 3000 is opened at a certain angle, it is convenient for the user to grip the door body 3000, so that the user can manually open the door. During the process of the user manually opening the door body 3000, the elastic potential energy stored in the spring can continue to increase. When the hinge vane 220 rotates to a certain angle and crosses the dead point, the length of the damping device 270 gradually increases, the guide rod 273 moves outward toward the outside of the guide sleeve 272, and the spring gradually releases the elastic potential energy, so that the damping force generated by the damping device 270 gradually decreases, enabling the user to smoothly open the door body 3000 to the preset angle or even fully open. When the door body 3000 is in the state of the maximum opening angle, the hinge vane 220 is in the Figures 7 - 9 second position as shown.

[0087] It should be noted that when the hinge vane 220 rotates to the dead point position, at this time, in the projection in the plane perpendicular to the rotating shaft 250, the rotation center of the rotating shaft 250, one of the hinge seat 210 and the hinge vane 220, the rotation center of one end of the guide sleeve 272, the hinge seat 210 and the other of the hinge vane 220, and the rotation center of one end of the guide rod 273 are collinear. At this time, the elastic potential energy stored in the spring is the largest. After crossing the dead point, the elastic potential energy of the spring gradually decreases and even drops to zero, thus ensuring that the user can smoothly open the door manually.

[0088] It can be seen that under the action of the elastic force, the door body 3000 can be sprung open, that is, the hinge vane 220 can start to rotate from the first position. Under the action of the damping device 270, the hinge vane 220 can stop at the preset position, that is, the door body 3000 can stop at a certain angle. Under the external force of the user, the hinge vane 220 can overcome the resistance of the damping device 270 and rotate to the second position, enabling the door body 3000 to reach the state of the maximum opening angle. Conversely, when the door body 3000 moves from the state of the maximum opening angle to the closed state, correspondingly, the hinge vane 220 can rotate from the second position to the first position.

[0089] As Figure 3 shown, in some examples, the guide rod 273 has a limit step 2733, and the limit step 2733 stops at one end of the spring. By setting the limit step 2733, the spring can be limited to prevent the spring from having too large a displacement on the guide rod 273 and being unable to generate damping, ensuring that the damping device 270 can work normally.

[0090] As Figure 2 and Figure 3As shown, in some examples, the guide rod 273 includes a first rod segment 2731 and a second rod segment 2732. The first rod segment 2731 and the second rod segment 2732 are arranged at an angle, that is to say, the guide rod 273 forms a bent rod. In some specific examples, the first rod segment 2731 and the second rod segment 2732 can be connected by an arc transition.

[0091] Wherein, the spring is sleeved on the first rod segment 2731, and one end of the second rod segment 2732 away from the first rod segment 2731 is rotatably connected to the other one of the hinge seat 210 and the hinge blade 220.

[0092] Thus, by setting the guide rod 273 into the above structure, on the one hand, the second rod segment 2732 can be used to achieve limit, the moving stroke of the guide rod 273 relative to the guide sleeve 272 can be limited, so that the maximum damping force that the damping device 270 can generate can be limited. On the other hand, the structural strength of the guide rod 273 can be improved, avoiding the deformation of the guide rod 273 under the action of external force, and ensuring the normal use of the damping device 270.

[0093] As Figure 1 , Figure 4 and Figure 7 shown, according to some embodiments of the present invention, the hinge seat 210 has a first fixing portion 217, the hinge blade 220 has a second fixing portion 227, and both ends of the damping device 270 are rotatably connected to the first fixing portion 217 and the second fixing portion 227 respectively, with a simple structure and convenient connection.

[0094] Wherein, the rotation axes of the damping device 270 with the first fixing portion 217 and the second fixing portion 227 are both parallel to the rotation axis of the rotating shaft 250, which can reduce the interference of the internal structure of the damping device 270 and ensure that the damping device 270 can work normally when the hinge blade 220 rotates.

[0095] As Figure 1 shown, in some embodiments, the first fixing portion 217 forms a fixing lug, and the fixing lug protrudes from the surface of the hinge seat 210. A connecting shaft 2172 can be provided on one of the fixing lug and the damping device 270, and a first shaft hole 2171 cooperating with the connecting shaft 2172 can be provided on the other one, so as to realize the rotational connection between the damping device 270 and the hinge seat 210. The structure of the fixing lug is simple and convenient to form, which is beneficial to reducing costs.

[0096] As Figure 1 shown, in some embodiments, the second fixing portion 227 forms a fixing shaft, and the fixing shaft is parallel to and spaced from the rotating shaft 250. Specifically, the hinge blade 220 is provided with a fixing shaft, and the damping device 270 is provided with a second shaft hole 2271 cooperating with the fixing shaft, so as to realize the rotational connection between the damping device 270 and the hinge blade 220.

[0097] As Figure 5 and Figure 6 shown, in some embodiments, when the hinge blade 220 is in a preset position, the rotation axes of the damping device 270 with the first fixing portion 217, the rotation axis of the damping device 270 with the second fixing portion 227, and the rotation axis of the rotating shaft 250 are coplanar.

[0098] In this state, the damping force generated by the damping device 270 is the largest. When the hinge blade 220 crosses the preset position, the damping force generated by the damping device 270 gradually decreases and even drops to zero, so as to ensure that the user can smoothly open the door manually.

[0099] As Figures 1 - 9 shown, according to some embodiments of the present invention, the hinge blade 220 includes a first connecting section 223, a second connecting section 224, and a transition section 225. One end of the first connecting section 223 is rotatably connected to the hinge base 210 through the rotating shaft 250. The second connecting section 224 is disposed on one side in the thickness direction of the first connecting section 223. Both ends of the transition section 225 are respectively connected to the other end of the first connecting section 223 and one end of the second connecting section 224, and at least part of the transition section 225 passes through the opening 214.

[0100] Furthermore, the connection position of the damping device 270 and the hinge blade 220 is located at the first connecting section 223, preventing interference between the damping device 270 and the hinge blade 220 and affecting the rotation of the hinge blade 220.

[0101] Among them, by connecting one end of the first connecting section 223 to the hinge base 210 through the rotating shaft 250, the rotational connection between the hinge blade 220 and the hinge base 210 can be realized; by passing at least part of 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 connecting section 223 and one end of the second connecting section 224 respectively, the fixed connection between the first connecting section 223 and the second connecting section 224 can be realized.

[0102] In some embodiments, the rotating shaft 250 is fixed to the hinge base 210. The first connecting section 223 of 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 intervals in the axial direction of the rotating shaft 250. Both the first connecting portion 2261 and the second connecting portion 2262 are rotationally matched with the rotating shaft 250, so as to realize the rotational connection between the hinge blade 220 and the hinge base 210.

[0103] 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 base 210, so as to realize the rotational connection between the hinge blade 220 and the hinge base 210.

[0104] As Figure 2 and Figure 3 、 Figure 5 and Figure 6 、 Figure 8 and Figure 9 shown, in some embodiments, the transition section 225 forms an arc structure, and the radial direction of the arc structure intersects 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 connecting section 224 is a straight structure.

[0105] 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 ensure the stability during the rotation process to a certain extent, that is, ensure the stability of the door body 3000 during the rotation process and ensure the working performance of the door body 3000.

[0106] 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 connection difficulty between the second connecting section 224 and the door body 3000 can also be reduced.

[0107] 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 interference of the first connecting section 223 during the rotation of the hinge blade 220 can be avoided to a certain extent, so that the hinge blade 220 can rotate effectively and ensure the stability during the rotation process to a certain extent.

[0108] 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.

[0109] In order to match modern homes, current laundry treatment devices are increasingly tending to be fully embedded or flush-mounted in the cabinet, but 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, on the basis of ensuring that the laundry treatment device 6000 can be fully embedded or flush-mounted in the cabinet, can open the door body 3000 to the maximum opening angle, and after opening the door body 3000, the hinge seat 210 cannot be seen, and the aesthetics is higher.

[0110] The laundry treatment device 6000 according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0111] As Figures 10 - 14As shown, a laundry treatment apparatus 6000 according to an embodiment of the present invention includes a cabinet assembly 1000 and a door 3000. The cabinet assembly 1000 has an opening 110, and the door 3000 is rotatably provided outside the cabinet assembly 1000 through a hinge assembly 2000. The door 3000 is used to open and close the opening 110, and the hinge assembly 2000 is the hinge assembly 2000 according to the above embodiment.

[0112] The laundry treatment apparatus 6000 further includes an automatic door opening assembly, which is used to open the door 3000 by a preset angle after the laundry treatment program of the laundry treatment apparatus 6000 ends, and the preset angle is less than or equal to the maximum door opening angle.

[0113] Among them, the hinge seat 210 of the hinge assembly 2000 is provided inside the cabinet assembly 1000, and the hinge seat 210 is connected to the cabinet assembly 1000. The door 3000 is connected to the hinge blade 220, hiding the hinge seat 210 inside the cabinet assembly 1000. When the door 3000 is opened, the hinge seat 210 will not be seen, which is beneficial to improving the visual experience of the laundry treatment apparatus 6000.

[0114] Since the hinge assembly 2000 according to the embodiment of the present invention has the above technical effects, the laundry treatment 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 3000 can be kept in a state of being opened by a preset angle. On the one hand, the controllability of the bouncing position of the door 3000 can be realized, reducing the impact force generated by the bouncing of the door 3000, thereby reducing the noise generated during the door opening process. On the other hand, if the automatically opened angle of the door 3000 is less than the maximum door opening angle, it is convenient for the user to grasp the door 3000 to manually open the door, especially for the scheme in which the door 3000 is embedded, the effect is more obvious.

[0115] In addition, by setting the automatic door opening assembly, on the one hand, after the laundry treatment program of the laundry treatment apparatus 6000 is executed and ends, the door 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 3000 has opened the opening 110, natural air can be introduced into the laundry treatment chamber, avoiding the generation of peculiar smell due to the clothes not being taken out for a long time; by arranging the hinge seat 210 inside the cabinet assembly 1000, when the door 3000 is opened, the hinge seat 210 will not be seen, which is beneficial to improving the visual experience of the laundry treatment apparatus 6000.

[0116] Such as Figure 13As shown, according to some embodiments of the present invention, the cabinet assembly 1000 includes an installation panel 102. A through opening 110 is provided in the installation panel 102. The door body 3000 is rotatably provided on the outer side of the installation panel 102 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 provided on the inner side of the installation panel 102. Here, the installation panel 102 can be the front panel of the laundry treatment device 6000.

[0117] As Figures 10 - 12 shown, the cabinet assembly 1000 further includes a cabinet 101. One side of the cabinet 101 has an opening. The 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.

[0118] As Figure 13 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 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.

[0119] 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 outer side of the installation panel 102 through the avoidance opening 120 to be connected to the door body 3000.

[0120] 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, it is used to realize the communication between the opposite sides in the thickness direction of the installation panel 102; 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 outer side of the installation panel 102 through the avoidance opening 120 to be connected to the door body 3000.

[0121] The door body 3000 is rotatably provided on the outer side of the installation panel 102 through the hinge assembly 2000. The door body 3000 is used to open and close the through opening 110. That is to say, the hinge assembly 2000 can realize rotatably setting the door body 3000 on the outer side 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 using the door body 3000 to open the through opening 110, the communication between the opposite sides of the installation panel 102 can be realized; when using the door body 3000 to close the through opening 110, the through opening 110 can be blocked.

[0122] 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 opening and closing the through opening 110 with the door body 3000, and to ensure the shielding effect to a certain extent when the door body 3000 closes the through opening 110.

[0123] It should also be noted that the above-mentioned door body 3000 can be a circular door body 3000, or 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 cabinet assembly 1000 can be rotatably connected through a hinge assembly 2000, and the hinge assembly 2000 can be provided 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 cabinet assembly 1000 can be rotatably connected through a hinge assembly 2000, or can be rotatably connected through a plurality of hinge assemblies 2000. When a plurality of 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, so as to ensure the stability of the door body 3000 during rotation to a certain extent.

[0124] It should be emphasized that in the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0125] In this embodiment, the hinge seat 210 and the door body 3000 are provided on the inner and outer 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 the inner and outer sides of the mounting panel 102 at the same time.

[0126] Among them, by providing the hinge seat 210 and the door body 3000 on opposite sides of the mounting panel 102, when the door body 3000 opens the through opening 110, the mounting panel 102 can be used to shield the hinge seat 210, so as to avoid the user directly observing the hinge seat 210 to a certain extent, thereby improving the aesthetic degree 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.

[0127] It should be noted that the above-mentioned outer side can be understood as Figure 13 the front side of the shown mounting panel 102, and the inner side can be understood as Figure 13The rear side of the mounting panel 102 shown in the figure has an inner side and an outer side that are oppositely arranged.

[0128] Of course, in some other embodiments, when the door body 3000 is located at the top of the cabinet 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.

[0129] By rotatably connecting the hinge blade 220 with the hinge seat 210 and extending at least a part of the hinge blade 220 to the outer side 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, which is convenient for controlling the rotation of the door body 3000 relative to the mounting panel 102 to realize the opening and closing of the access opening 110 by using the door body 3000, and reducing the difficulty of opening and closing the access opening 110.

[0130] From the above structure, it can be seen that by providing the avoidance opening 120 on the mounting panel 102, a part of the hinge assembly 2000 can be arranged on the inner side of the mounting panel 102 and another part of the hinge assembly 2000 can be arranged on the outer side of the mounting panel 102 to connect with the door body 3000, so as to realize 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 also be improved, and the aesthetic degree of the laundry treatment device 6000 can be increased.

[0131] In some embodiments, as shown in Figure 1 、 Figure 4 and Figure 7 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, so as to realize the fixed connection between the hinge seat 210 and the mounting panel 102, which is convenient for using the mounting panel 102 to support the hinge seat 210 and improve the position stability of the hinge seat 210.

[0132] 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 using the first fastener, the hinge seat 210 and the mounting panel 102 can also form a detachable connection, so as to reduce the connection difficulty between the hinge seat 210 and the mounting panel 102 and improve the connection efficiency.

[0133] 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.

[0134] Such as Figure 1 、 Figure 4 andFigure 7 As shown, in some embodiments, the hinge base 210 includes a first base body 215 and a second base body 216. The second base body 216 is connected to one end of the first base body 215, and the rotating shaft 250 is provided on the second base body 216 so that the hinge blade 220 is rotatably connected to the second base body 216.

[0135] The opening 214 can be provided on the first base body 215, or on the second base body 216, or a part of it can be provided on the first base body 215 and another part on the second base body 216.

[0136] Wherein, the connection position of the damping device 270 with the hinge base 210 is located on the first base body 215, preventing the damping device 270 from interfering with the hinge blade 220 and affecting the rotation of the hinge blade 220.

[0137] Here, it means that the hinge base 210 includes a first base body 215 and a second base body 216 that are connected to each other, and 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 also be reduced.

[0138] At the same time, by providing the 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 hinge blade 220 interfering with the hinge base 210 during rotation, thereby ensuring the smoothness of the rotation of the hinge blade 220 to a certain extent and improving the working performance of the hinge assembly 2000.

[0139] Optionally, as Figure 13 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 using the mounting panel 102 to support the hinge base 210, improve the position stability of the hinge base 210, that is, improve the position stability of the hinge assembly 2000, and ensure the working performance of the hinge assembly 2000 to a certain extent.

[0140] In addition, with the above arrangement, the connection points of the first seat body 215 and the second seat body 216 with 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 seat 210 and the mounting panel 102, thereby reducing the connection difficulty between the hinge seat 210 and the mounting panel 102.

[0141] In some embodiments, as shown in Figure 1 、 Figure 4 and Figure 7 , first connection holes 213 are provided at one end of the first seat body 215 away from the second seat body 216 and at one end of the second seat body 216 away from the hinge blade 220. The first seat body 215 and the second seat body 216 are respectively fixedly connected to the mounting panel 102 through the first connection holes 213 to achieve the fixed connection between the hinge seat 210 and the mounting panel 102.

[0142] In summary, the hinge seat 210 of the present application includes a first seat body 215 and a second seat body 216 connected to each other. The first seat body 215 is used to achieve the fixed connection between the hinge seat 210 and the mounting panel 102, and the second seat body 216 is used to achieve 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.

[0143] 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 side of the main panel 142.

[0144] 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 in 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.

[0145] 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 achieving 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 achieving 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.

[0146] Meanwhile, since the installation part 150 is provided with an avoidance opening 120, after connecting the installation part 150 to the main panel 142, the through opening 110 and the avoidance opening 120 can be defined, thereby realizing the formation of the through opening 110 and the avoidance opening 120 on the installation panel 102.

[0147] In some embodiments, such as Figure 13 shown, the installation part 150 is arranged on the inner circumferential side of the panel body 140, and the installation part 150 is formed as an annular structure to define the through opening 110.

[0148] 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 forms the above-mentioned through opening 110, and the side wall of the recessed region forms the above-mentioned avoidance opening 120, thereby realizing the formation of the through opening 110 and the avoidance opening 120 on the installation panel 102.

[0149] 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.

[0150] In some embodiments, such as Figure 13 shown, at least part of the connecting flange 160 protrudes towards the main panel 142 to form an insertion interface 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 board 2151 that is inserted and matched with the insertion interface 161. The insertion board 2151 is matched with the insertion interface 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.

[0151] In some embodiments, such as Figure 1 、 Figure 4 and Figure 7As shown, the plug-in board 2151 is provided with a first connection hole 213. In the process of connecting the hinge seat 210 to the mounting panel 102, the plug-in board 2151 can be first inserted and fitted into the insertion port 161 to achieve preliminary positioning of the hinge seat 210. Subsequently, the hinge seat 210 and the mounting panel 102 are connected by a first fastener to achieve a fixed connection between the hinge seat 210 and the mounting panel 102, reducing the connection difficulty between the hinge seat 210 and the mounting panel 102.

[0152] As Figure 1 , Figure 4 and Figure 7 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 far from the first extension section 2161. That is to say, the second seat body 216 includes a first extension section 2161 and a second extension section 2162 connected to each other, and the hinge blade 220 is connected to the end of the second extension section 2162 far from the first extension section 2161 to achieve the connection of the hinge blade 220 to the hinge seat 210.

[0153] Optionally, the end of the first extension section 2161 far from the second extension section 2162 is connected to the mounting panel 102. It can be understood here that the ends of the first extension section 2161 and the second extension section 2162 far from each other are respectively connected to the mounting panel 102 and the hinge blade 220. In this way, while achieving the fixed connection between the hinge seat 210 and the mounting panel 102 and the rotational connection between the hinge seat 210 and the hinge blade 220, the interference between the hinge blade 220 and the mounting panel 102 during the assembly process of the hinge seat 210 can be avoided, reducing the assembly difficulty of the hinge assembly 2000.

[0154] Combined with Figure 13 , the mounting portion 150 includes a first region 151 and a second region 152. The second region 152 is connected between the panel body 140 and the first region 151 and is inclined relative to the panel body 140 and the first region 151, and the avoidance opening 120 is provided in the second region 152. Among them, by connecting the second region 152 between the panel body 140 and the first region 151, the fixed connection between the panel body 140 and the first region 151 is achieved, making the relative position between the panel body 140 and the first region 151 stable, thereby ensuring the structural stability of the mounting panel 102.

[0155] Meanwhile, by setting the second region 152 to be inclined with respect to the panel body 140 and the first region 151, and disposing the avoidance opening 120 in the second region 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 be avoided that when the hinge blade 220 rotates relative to the avoidance opening 120, the hinge blade 220 interferes with the second region 152, ensuring smooth rotation of the hinge blade 220.

[0156] In a specific example, as Figure 13 shown, the second region 152 is connected to one end of the main panel 142 away from the side plate 141 and is inclined with respect 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 enabling at least a part of the mounting portion 150 to be inclined with respect to the panel body 140, which is convenient for arranging the avoidance opening 120 for avoiding the rotation of the hinge blade 220 on the mounting portion 150.

[0157] In some embodiments, the door body 3000 is disposed on the front side of the mounting panel 102, the first region 151 is disposed 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 avoid interference between the hinge blade 220 and the second region 152 during rotation, ensuring smooth rotation of the hinge blade 220.

[0158] 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 features, without order or importance.

[0159] In some embodiments, in combination with Figure 1 、 Figure 4 and Figure 7 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 provided on the door body 3000, and the second connection hole 2242 and the second mating hole are fixedly connected by a second fastener, thereby realizing the fixed connection between the hinge blade 220 and the door body 3000, facilitating the use of the hinge blade 220 to realize the rotational connection between the door body 3000 and the mounting panel 102, and thus ensuring the working performance of the door body 3000 to a certain extent.

[0160] 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, reducing the connection difficulty between the hinge blade 220 and the door body 3000 and improving the connection efficiency.

[0161] Of course, in some other embodiments, the hinge blade 220 and the door body 3000 may also be non-detachably connected by bonding, welding, etc., and no specific limitation is made here.

[0162] In some embodiments, in combination Figure 1 , Figure 4 and Figure 7 As shown, on a part of the hinge blade 220 extending to the outside of the mounting panel 102, there is provided a positioning convex portion 2241, and a positioning hole (not shown in the figure) matching the positioning convex portion 2241 is provided on the door body 3000.

[0163] Through the above settings, 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, so that the relative position between the hinge blade 220 and the door body 3000 is 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.

[0164] 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 matching the external thread. The external thread and the internal thread are connected in a matching manner to connect the rotating shaft 250 to the hinge seat 210, thereby facilitating the use of the rotating shaft 250 to achieve the rotational connection between the hinge blade 220 and the hinge seat 210.

[0165] According to some embodiments of the present invention, the laundry treatment device 6000 further includes a laundry treatment drum assembly 5000. The laundry treatment drum assembly 5000 is disposed in the cabinet assembly 1000, and the laundry treatment drum assembly 5000 defines a laundry treatment cavity. The laundry treatment cavity has a laundry access opening 510, and the laundry access opening 510 is disposed opposite to the through opening 110. When the door body 3000 is in a state of closing the through opening 110, the door body 3000 can close the laundry access opening 510.

[0166] As Figures 10 - 13 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 disposed on the cabinet assembly 1000 and the other is disposed 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.

[0167] As Figure 14As shown, the automatic door opening assembly further includes a jacking member 330, which 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.

[0168] Specifically, Figure 10 FIG. shows a schematic structural view of the laundry treatment apparatus 6000 when the door body 3000 is in the closed state. Figure 11 FIG. shows a schematic structural view of the laundry treatment apparatus 6000 when the door body 3000 is in the state of being opened by a preset angle. Figure 12 FIG. shows a schematic structural view of the laundry treatment apparatus 6000 when the door body 3000 is in the state of being opened at the maximum opening angle.

[0169] Among them, as Figure 14 shown, in this embodiment, a jacking member 330 is provided on the side of the door body 3000 facing the cabinet assembly 1000. The jacking member 330 is used to jack open the door body 3000 after the laundry treatment program of the laundry treatment apparatus 6000 ends and when the door lock 310 is disengaged from the door hook 320.

[0170] Specifically, the jacking member 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 the position extending out of the door body 3000.

[0171] As Figure 10 shown, when the door body 3000 of the laundry treatment apparatus 6000 is in the closed state, the jacking member 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.

[0172] As Figure 11 shown, after the laundry treatment program of the laundry treatment apparatus 6000 ends, when the door opening execution order is executed, the door lock 310 is unlocked, the door hook 320 is released, and the jacking member 330 releases the elastic force to jack 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 force or the inertial force generated due to the door body 3000 being bounced open, so that the door body 3000 stops at the set state. At this time, the hinge blade 220 is in the preset position.

[0173] Since Figure 11The door body 3000 in it is opened at a certain angle, thus facilitating 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, enabling the user to smoothly open the door body 3000 to a preset angle or even fully open it. When the door body 3000 is in Figure 12 the state of the maximum opening angle in it, the hinge blade 220 is in the second position.
