[0061] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above-described accompanying drawings.

[0062] In this application, the terms "comprise", "comprising", "include", "including", "have", "has", "contain", "containing", or any other any other variant thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element preceded by "comprises a" does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0063] In this application, the term "and / or", is a descriptive association relationship of associated objects, which means that there can be three relationships. For example, A and / or B, can represent the following three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in this application generally represents that the front and rear associated objects are in a "and / or" relationship.

[0064] In this application, the terms "connected", "coupled", "engage", "engagement", "attached" can be direct connection, coupling or engagement, or indirect connection, coupling or engagement through an intermediate part. For example, direct connection refers to two parts or components connected together without an intermediate part, and indirect connection refers to two parts or components connected to at least one intermediate part, and the two parts or components are connected through the intermediate part. In addition, "connection" and "coupling" are not limited to physical or mechanical connection or coupling, and can include electrical connection or coupling.

[0065] In this application, those of ordinary skill in the art will understand that the relative terms used in connection with the quantity or condition (for example, "about", "approximately", "substantially" and the like) include the value indicated and have the meaning indicated by the context. For example, the relative terms at least include the degree of error related to the measurement of the specific value, the tolerance caused by manufacturing, assembly, use and the like related to the specific value. Such terms should also be considered to disclose the range defined by the absolute values of the two endpoints. The relative terms can refer to a certain percentage (for example, 1%, 5%, 10% or more) of the indicated value. The numerical value without the relative term should also be disclosed as a specific value with tolerance. In addition, "substantially" when expressing the relative angular position relationship (for example, substantially parallel, substantially perpendicular), can refer to a certain degree (for example, 1 degree, 5 degrees, 10 degrees or more) added or subtracted from the indicated angle.

[0066] In this application, those of ordinary skill in the art will understand that the function performed by the component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by the part can also be performed by one part, one component, or multiple parts in combination.

[0067] In this application, the terms "up", "down", "left", "right", "front", "back" and the like are described in the orientation and positional relationship shown in the drawings, and should not be understood as limiting the embodiments of the application. In addition, it should also be understood in the context that when referring to one element connected to another element "up" or "down", it can not only be directly connected to another element "up" or "down", but also indirectly connected to another element "up" or "down" through an intermediate element. It should also be understood that the terms "up", "down", "left", "right", "front", "back" and the like not only represent the positive direction, but also can be understood as the side direction. For example, the lower side can include the lower side, the lower left side, the lower right side, the lower front side and the lower back side, etc.

[0068] Figure 1 The structure schematic diagram of the fabric treatment device provided by the embodiments of the application in one state is shown. Figure 2 The structure schematic diagram of the fabric treatment device provided by the embodiments of the application in another state is shown. As shown inFigures 1-2 As shown, the fabric treatment apparatus includes a cabinet 100, a tub 200 and a door 300, the tub 200 is installed in the cabinet 100, and the tub 200 has an opening for taking and placing fabrics, and the door 300 is rotatably installed on the cabinet 100 about a first axis and is used to open or close the opening of the tub 200. It can be understood that the fabric treatment apparatus can be a washing machine or a dryer or a washer-dryer, which is not limited here.

[0069] For the convenience of description, the direction of the opening of the tub 200 of the fabric treatment apparatus is defined as "front", the direction of the closed end of the tub 200 is defined as "back"; when a user faces the fabric treatment apparatus, the left hand side of the user is defined as "left", and the right hand side of the user is defined as "right"; the upper of the height direction of the cabinet 100 is defined as "up", and the lower of the height direction of the cabinet 100 is defined as "down". In addition, it needs to be particularly pointed out that the left-right orientation description of the door 300 is based on the left-right of the door 300 in the closed state.

[0070] The fabric treatment apparatus further includes a door lock mechanism to ensure that the door 300 can be locked with the cabinet 100 in the closed state, to avoid the door 300 being opened in the working state of the fabric treatment apparatus, and to improve the safety of the product.

[0071] The door lock mechanism includes a lock body assembly 401 and a lock tongue assembly 402, the lock body assembly 401 is installed on the right front side of the cabinet 100, and the lock tongue assembly 402 is installed on the right rear side of the door 300, and in the closed state of the door 300, the lock tongue assembly 402 can cooperate with the lock body assembly 401 to achieve locking, so as to avoid the door 300 being opened. In an embodiment, the door lock mechanism can be an electric door lock or a pure mechanical door lock, as long as the lock structure that can lock the door 300 on the cabinet 100 can be applied to the fabric treatment apparatus of the present application.

[0072] In the related art, when taking and placing fabrics, the user needs to exert a certain force to rotate the door 300 to achieve the unlocking and opening or closing and locking operation. However, after the door 300 is used for a long time, part of the structure of the door 300 will be slightly deformed, such as the door 300 sagging, so that the door 300 does not cooperate with the cabinet 100, thereby causing the unlocking and opening or closing and locking operation to be more time-consuming and laborious, and the user experience is poor. In addition, after the fabrics are washed, the temperature and humidity in the tub 200 are high, and if the user does not open the door 300 in time, the fabrics stored in the tub 200 for a long time are easy to breed bacteria, and even the fabrics can be secondarily contaminated.

[0073] To solve the above problems, the application provides an automatic door opening and closing mechanism 500 for rotatably mounting a door body 300 on a box body 100 about a first axis, and capable of achieving a certain degree of automatic opening and closing of the door body 300 during door closing and opening operations, so as to make the user's unlocking and opening or closing operation more time-saving and labor-saving, and also automatically open the door body in time after the fabric is washed, so as to solve the problem that the temperature or humidity in the barrel of the fabric treatment device is high after the fabric is washed, and if the user does not open the door body in time, the fabric is likely to breed bacteria for a long time in the barrel, and even cause secondary pollution to the fabric, and improve the user's opening and closing operation experience.

[0074] Figure 3 An exploded view of the automatic door opening and closing mechanism 500 is shown. Figure 4 An exploded view of the automatic door opening and closing mechanism 500 is shown. Figure 2 A partial structure schematic view of the fabric treatment device is shown. Figure 5 An exploded view of the door body 300 is shown. Figure 6 An exploded view of the door body 300 is shown. Figure 5 A partial structure schematic view of the door body 300 is shown. As shown in the figure, Figures 3-6 The automatic door opening and closing mechanism 500 includes a fixed frame 11 and a rotating part 12, the fixed frame 11 is fixed to the box body 100, and the rotating part 12 is rotatably mounted on the fixed frame 11 about a first axis and fixedly connected with the door body 300, so as to realize the rotation of the door body 300 relative to the box body 100 about the first axis.

[0075] The automatic door opening and closing mechanism 500 further includes a first pivot 10 and an automatic door opening and closing module 13, wherein the automatic door opening and closing module 13 includes a bracket 131, a cam 132, an energy storage assembly 133 and a second pivot 134, the first pivot 10 is fixedly connected with the fixed frame 11, the first end of the bracket 131 is rotatably sleeved on the first pivot 10, the second end of the bracket 131 is fixedly connected with the door body 300, the cam 132 is fixed on the first pivot 10, and the cam 132 cooperates with the energy storage assembly 133 to realize the automatic closing and opening of the door body 300, so as to save time and labor for the user during the opening and closing operation. In this embodiment, the fixed frame 11 includes a first fixed part 111 and a second fixed part 112, the first fixed part 111 is fixed to the left front side of the box body 100, one end of the second fixed part 112 is fixedly connected with the first fixed part 111, and the other end of the second fixed part 112 is fixedly connected with the first pivot 10. Wherein, the extension direction of the first pivot 10 is the same as the extension direction of the first axis, and the rotating part 12 is rotatably sleeved outside the first pivot 10.

[0076] The second fixing member 112 is used to connect the first fixing member 111 and the first pivot 10, and the line between the connecting position between the second fixing member 112 and the first fixing member 111 and the connecting position between the second fixing member 112 and the first pivot 10 is arranged at an obtuse angle with the plane where the first fixing member 111 is located. In the embodiment, the second fixing member 112 is L-shaped, the first branch of which is fixedly connected with the first fixing member 111, and the second branch of which is fixedly connected with the first pivot 10, so that the first pivot 10 is staggered with the first fixing member 111 in the front-back direction, and enough space is reserved for the rotation of the door body 300. This is because the door body 300 usually has a certain thickness, and if the first pivot 10 is directly fixed to the first fixing member 111, the door body 300 is likely to interfere with the cabinet 100 during rotation, which is not conducive to the opening and closing of the door body 300, and also affects the service life of the door body 300.

[0077] In the embodiment, the number of the second fixing members 112 is two, and the two second fixing members 112 are arranged at intervals along the extension direction of the first axis, and the number of the first pivots 10 is also two, and the two first pivots 10 are respectively fixed to the two second fixing members 112. In this way, not only the assembly of the fixing frame 11 can be facilitated, but also the stability of the rotational connection between the door body 300 and the cabinet 100 can be improved.

[0078] Further, the rotating member 12 includes a rotating sleeve part 121 and a first mounting part 122, the rotating sleeve part 121 is rotationally matched with the first pivot 10, and the mounting part 22 is fixed to the door body 300. In the embodiment, the number of the rotating members 12 is three, one end of one of the first pivots 10 is connected with the rotating member 12, and the other end of the first pivot 10 is connected with the rotating member 12, and the other end of the first pivot 10 is connected with the rotating member 12. Through the arrangement of the three rotating members 12, the stability of the connection between the door body 300 and the first pivot 10 can be improved, and the stable rotation of the door body 300 can be ensured.

[0080] In the embodiment, the first pivot 10 has a flat shaft portion matched with the cam 132, and the cam 132 has a flat hole matched with the flat shaft portion. In addition, the cam 132 has a threaded hole communicated with the flat hole, and a bolt is screwed with the threaded hole and abuts against the flat shaft portion of the first pivot 10 to fix the cam 132 to the first pivot 10. In this way, the relative rotation between the first pivot 10 and the cam 132 is prevented, and the stability of the automatic door opening and closing mechanism 500 is ensured.

[0081] It can be understood that in other embodiments, the portion matched with the cam 132 of the first pivot 10 can not be flat shaft-shaped, but can be a non-cylindrical structure, which will not be described one by one here.

[0082] The bracket 131 includes a surrounding wall portion 1311, a first connecting portion 1312 and a second connecting portion 1313. The first connecting portion 1312 is connected to a first end of the surrounding wall portion 1311 and has a rotating hole for rotating matching with the first pivot 10. The second connecting portion 1313 is connected to a second end of the surrounding wall portion 1311 and is limitingly installed in the door body 300. In the embodiment, the number of the first connecting portions 1312 is two, and the two first connecting portions 1312 are arranged in parallel and at intervals. The number of the second connecting portions 1313 is two, and the two second connecting portions 1313 are arranged in parallel and at intervals.

As shown in Figure 9 In combination Figure 7 As shown, in the thickness direction of the door body 300 (i.e. the front-rear direction of the fabric treatment device), the support 131 is clamped between the support 302 and the rear door frame 303, and the limiting of the support 131 in the front-rear direction can be realized. In this way, on the one hand, the limiting installation of the support 131 can be realized without using fastening bolts, and on the other hand, the cracking of the support 131 or the door body 300 caused by stress concentration due to rigid connection of the bolts can be avoided.

[0086] In other words, the support 131 realizes the limiting in the plane direction of the door body 300 through the cooperation of the first limiting column 3021 and the second limiting column 3022 on the support 302, and realizes the limiting in the front-rear direction through the cooperation of the support 302 and the rear door frame 303, so as to ensure that when the energy storage assembly 133 moves relative to the guide track of the cam 132, the energy storage assembly 133 can drive the door body 300 to automatically open or automatically close in a small range through the support 131.

[0087] Continuing as Figure 9 In combination Figure 7 As shown, the energy storage assembly 133 includes a first mounting part 1331, a second mounting part 1332 and an elastic part 1333, the elastic part 1333 is located between the first mounting part 1331 and the second mounting part 1332, and is used to realize the elastic movement of the second mounting part 1332 relative to the first mounting part 1331, the first end of the first mounting part 1331 forms the first end of the energy storage assembly 133, and is used to be swing-connected with the support 131, and the second end of the second mounting part 1332 forms the second end of the energy storage assembly 133, and is used to cooperate with the guide track.

[0088] The first mounting member 1331 is a first sleeve with a closed end, and the closed end of the first sleeve forms a first end of the energy storage assembly 133. The second mounting member 1332 is slidably mounted in the first sleeve along the extension direction of the first sleeve. The second mounting member 1332 is a second sleeve with a closed end, and the opening of the second sleeve faces the closed end of the first sleeve. The inner cavity of the second sleeve cooperates with the inner cavity of the first sleeve to form a containing space. The elastic member 1333 is accommodated in the containing space, and the elastic deformation direction of the elastic member 1333 is the same as the center line extension direction of the containing space. The elastic member 1333 is used to automatically move the second end of the energy storage assembly 133 along the guide rail in a small range.

[0089] In order to reduce the friction between the second end of the energy storage assembly 133 and the guide rail, the second mounting member 1332 includes a second mounting portion 13321 and a plurality of rolling balls 13322 rotatably mounted in the second mounting portion 13321. The rolling balls 13322 are in rolling cooperation with the guide rail. In this way, the friction between the second end of the energy storage assembly 133 and the guide rail becomes rolling friction, and the rolling friction is much smaller than the sliding friction, which can ensure the stable movement of the energy storage assembly 133 relative to the guide rail.

[0090] In order to realize the automatic movement of the energy storage assembly 133 relative to the guide rail in a small range, in addition to the structure of the energy storage assembly 133, the track and trend of the guide rail also need to be matched. Based on this, the embodiment of the present application designs a guide rail which can cooperate with the energy storage assembly 133 to realize the automatic rotation of the support 131 relative to the first pivot 10, and then realize the rotation of the door body 300 in a small range.

[0091] Figure 10 A structural schematic diagram of the cam 132 in one direction provided by the embodiment of the present application is shown. Figure 11 A schematic diagram of the track and trend of the guide rail provided by the embodiment of the present application is shown. As shown in Figures 10-11 And as shown in Figure 7 The guide rail has a manually opening and closing door rail 13201, an automatic closing door rail 13202, an automatic opening door rail 13203 and a manually opening door energy storage rail 13204 connected in sequence. The manually opening door energy storage rail 13204 is connected to the middle position of the manually opening and closing door rail 13201. The automatic closing door rail 13202 and the automatic opening door rail 13203 are approximately U-shaped transition. The distance between the automatic closing door rail 13202 and the first axis (i.e. the center line of the first pivot 10) gradually decreases along the closing direction, and the distance between the automatic opening door rail 13203 and the first axis (i.e. the center line of the first pivot 10) gradually decreases along the opening direction.

[0092] In addition, the distance of the manual door opening and energy storage track 13204 from the first axis (i.e. the center line of the first pivot 10) gradually increases in the door opening direction. When the energy storage assembly 133 moves from the starting point to the end point of the manual door opening and energy storage track 13204, the elastic member 1333 is compressed to store energy. In other words, during the movement of the energy storage assembly 133 along the manual door opening and closing track 13201, the elastic member 1333 is always in a compressed state; during the movement of the energy storage assembly 133 from the starting point to the end point of the automatic door closing track 13202 and from the starting point to the end point of the automatic door opening track 13203, the elastic member 1333 is elongated and releases elastic force, so that the energy storage assembly 133 automatically moves along the automatic door closing track 13202 and the automatic door opening track 13203.

[0093] Since the automatic door closing track 13202 and the automatic door opening track 13203 are located at different positions in the axial direction of the cam 132 wheel surface, in order to ensure that the second end (ball 13322) of the energy storage assembly 133 can smoothly switch between the automatic door closing track 13202 and the automatic door opening track 13203, the energy storage assembly 133 as a whole should be able to swing within a certain range relative to the bracket 131 in the extension direction of the first pivot 10. Therefore, the bracket 131 has a movable space, and the closed end of the first mounting member 1331 is swingably mounted in the movable space through the second pivot 134. Further, the second connecting portion 1313 of the bracket 131 has a fixing hole for fixing the second pivot 134, and the closed end of the first mounting member 1331 is in rotational cooperation with the second pivot 134. It can be understood that the closed end of the first mounting member 1331 can be a through hole in rotational cooperation with the second pivot 134, or a circular arc groove in rotational cooperation with the second pivot 134, which is not limited here.

[0094] For the convenience of understanding, the opening and closing process of the door body 300 will be described below in conjunction with the drawings, and the initial state of the door body 300 is assumed to be the open door state. At this time, the elastic member 1333 of the energy storage assembly 133 is in a compressed energy storage state, and the operation process of manual door closing, automatic door closing, automatic door opening and manual door opening is as follows: Figures 1-11

[0095] 1) Manual door closing process: the user manually pushes the door body 300 to rotate in the door closing direction. During this process, the ball 13322 of the energy storage assembly 133 moves along the manual door opening and closing track 13201 in the door closing direction until the ball 13322 moves to the junction of the manual door opening and closing track 13201 and the automatic door closing track 13202, and the length of the elastic member 1333 does not change, i.e. the elastic force stored by the elastic member 1333 is not used.

[0096] ​2) Automatic closing process: due to the gradually decreasing distance between the automatic closing track 13202 and the center line of the first pivot 10 in the closing direction, and under the elastic action of the elastic member 1333 and the inertial action of the energy storage assembly 133, the ball 13322 of the energy storage assembly 133 can automatically continue to move in the closing direction along the automatic closing track 13202, until it moves to the junction between the automatic closing track 13202 and the automatic opening track 13203, and the latch assembly 402 on the door body 300 cooperates with the lock assembly 401 on the cabinet 100 to lock the door body 300 on the cabinet 100. In this automatic closing process, the elastic force released by the elastic member 1333 in the energy storage assembly 133 can save manpower and improve user operation experience.

[0097] 3) Automatic opening process: first, ensure that the latch assembly 402 on the door body 300 and the lock assembly 401 on the cabinet 100 are in an unlocked state. Then, due to the gradually decreasing distance between the automatic opening track 13203 and the first axis in the opening direction, and under the elastic action of the elastic member 1333, the ball 13322 of the energy storage assembly 133 can automatically move in the opening direction along the automatic opening track 13203, until it moves to the junction between the automatic opening track 13203 and the manual opening energy storage track 13204, at which time the length of the elastic member 1333 is at the maximum length.

[0098] 4) Manual opening process: used to manually push the door body 300 to rotate in the opening direction and open the door body 300 to the desired position. In this process, the ball 13322 of the energy storage assembly 133 moves along the manual opening energy storage track 13204 to the manual opening and closing track 13201, and the elastic member 1333 of the energy storage assembly 133 is compressed to store energy for the next automatic closing and automatic opening.

[0099] The fabric treatment device provided in the application not only retains the manual opening and closing function, but also can automatically open and close the door, has high product integration, simple structure, and makes the user's closing and locking and opening and unlocking operation more time-saving and labor-saving, effectively promotes the intelligent development and popularization of the product.

[0101] Referring to Figures 12-13 As shown, the second automatic door opening and closing mechanism differs from the first automatic door opening and closing mechanism mainly in that:

[0102] 1) The connection mode of the first pivot 20, the fixed frame 21 and the rotating member 22 is different.

[0105] 3) The structure of the rotating member 22 is different. Specifically, in the present embodiment, the rotating member 22 is a one-piece structure, and the rotating member 22 includes a rotating sleeve portion 221 and a first mounting portion 222, the rotating sleeve portion 221 is two in number, and the two rotating sleeve portions 221 are arranged along the first axis direction at intervals, the rotating sleeve portion 221 is in rotating cooperation with the first pivot 20, and the first mounting portion 222 is fixed to the door body 300.

It should be understood by those skilled in the art that the above embodiments do not limit the present application in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present application.
