The locking part is provided on the support member, and the mating part is correspondingly provided on the pivot structure.

[0019] The drive unit includes a cam rotatably mounted on the door body, the rotation axis of the cam being intersected with the rotation axis of the door body, the peripheral sidewall of the cam being in contact with the end face of the support member, and when the cam rotates to the first position, it drives the support member to move so that the locking part on it disengages from the mating part; when the cam rotates to the second position, it drives the support member to move so that the locking part on it locks into the mating part.

[0020] The side of the door body is provided with a clearance groove at the position corresponding to the cam, so that the cam is exposed;

[0021] The drive structure also includes a lever, one end of which is inserted into the clearance groove and connected to the cam, and the other end of which is used for the user to turn.

[0030] The door assembly provided by this utility model includes a door body, a locking structure, and a driving structure. One side of the door body is rotatably mounted to the machine body via a pivot structure. After the garment processing equipment completes its processing, the user opens the door to allow for heat dissipation or moisture dissipation. The driving unit drives the locking unit to move, causing the locking unit to engage with the mating unit. At this point, the door body is relatively fixed to the machine body, and the door body can maintain a fixed angle. This not only prevents the door body from rotating arbitrarily, ensuring that pets cannot enter the processing chamber through the opening, but also allows for heat dissipation or moisture dissipation.

[0050] Clothing handling equipment refers to household or commercial appliances used for cleaning, caring for, and organizing clothes. Taking a front-loading washing machine as an example, after washing clothes, to prevent the drum from becoming damp, users usually keep the drum door open to help the drum dissipate moisture and dry.

[0051] To prevent the door 1 from being opened by rotation at will, this utility model improves the door assembly 100 of the clothing processing equipment 1000. The structure of the door assembly 100 will be described in detail below with reference to the accompanying drawings.

[0052] The machine body 200 has a processing chamber with an opening on one side, allowing users to insert or remove clothing from the processing chamber. A door 1 is also provided, with one side of the door 1 rotatably mounted to the machine body 200 via a pivot structure 2. The door 1 can rotate relative to the machine body 200 to open or close the opening.

[0053] In this utility model, please refer to Figure 1 and Figure 2 The door assembly 100 also includes a locking structure 3 and a driving structure 4. The locking structure 3 includes a locking part 31 and a mating part 32 respectively disposed on the door body 1 and the pivot structure 2. The locking part 31 is movably disposed to engage or disengage with the mating part 32, thereby fixing or moving the door body 1 relative to the machine body 200. The driving structure 4 includes a driving part 41 motive-connected to the locking part 31. The driving part 41 is movably disposed on the door body 1, enabling the locking part 31 to engage or disengage with the mating part 32 during its movement.

[0054] After the garment processing equipment 1000 completes its processing, the user will open the door 1 to allow for heat dissipation or moisture dissipation. The drive unit 41 drives the locking unit 31 to move, causing the locking unit 31 to engage with the mating unit 32. At this time, the door 1 is relatively fixed to the machine body 200, and the door 1 can be maintained at a fixed angle. In this way, not only can the door 1 be prevented from being rotated at will, ensuring that pets cannot enter the processing chamber through the opening, but it can also maintain heat dissipation or moisture dissipation.

[0055] In one embodiment, please refer to Figures 2 to 8 The door assembly 100 also includes an elastic element 5, which is suspended from the door body 1 and is disposed corresponding to the pivot structure 2. A drive unit 41 drives the elastic element 5 so that, during its movement, a portion of the elastic element 5 can deform or return to its original position, causing that portion to move closer to or further away from the pivot structure 2. A locking part 31 is disposed at the deformed portion of the elastic element 5 to lock into the mating part 32 when the elastic element 5 deforms and to disengage from the mating part 32 when the elastic element 5 returns to its original position.

[0056] When the door 1 is opened to a predetermined angle and needs to maintain that angle, the drive unit 41 drives a local deformation of the elastic element 5, causing it to move closer to the pivot structure 2. At this time, the locking part 31 on the elastic element 5 locks into place with the mating part 32. The elastic element 5 makes the locking engagement between the locking part 31 and the mating part 32 tighter. When the elastic element 5 deforms, the locking part 31 and the mating part 32 lock together. The elastic element 5 can provide a continuous force, ensuring a stable locking state and preventing accidental unlocking due to external vibrations or other factors, thus improving the reliability of the door assembly 100 locking.

[0057] When the door 1 needs to be rotated, the drive unit 41 moves to partially reset the elastic element 5 so that its corresponding movement moves away from the rotating shaft structure 2. At this time, the locking part 31 on the elastic element 5 disengages from the cooperating part 32 and is unlocked.

[0058] By placing the locking part 31 at the deformation portion of the elastic member 5, the locking and unlocking functions are achieved through the deformation and reset of the elastic member 5. This eliminates the need for a complex mechanical transmission mechanism, simplifying the overall structure of the door assembly 100. This not only reduces manufacturing costs but also reduces potential failure points caused by too many components, improving the stability and reliability of the door assembly 100.

[0059] Meanwhile, the cushioning effect of the elastic element 5 can reduce the impact and wear between the locking part 31 and the mating part 32 during locking and unlocking. When the elastic element 5 deforms, it can absorb some energy, reduce the collision force between the locking part 31 and the mating part 32, thereby extending the service life of these components.

[0060] Specifically, the elastic element 5 and the rotating shaft structure 2 are arranged side by side at intervals in the height direction F1 of the fuselage 200. In the height direction F1 of the fuselage 200, a locking part 31 and a mating part 32 are respectively provided between the two opposing surfaces of the elastic element 5 and the rotating shaft structure 2. The driving part 41 can move at least in the height direction F1 of the fuselage 200 to drive the elastic element 5 to deform or reset in the height direction F1 of the fuselage 200.

[0061] This utility model does not impose specific limitations on the cooperation form of the locking part 31 and the mating part 32. In one embodiment, the locking part 31 and the mating part 32 are respectively configured as a locking post and a locking groove.

[0062] In one embodiment, please refer to Figures 5 to 9 A first tooth 33 and a second tooth 34 are respectively provided between the two surfaces of the elastic member 5 and the rotating shaft structure 2. When the elastic member 5 deforms, the first tooth 33 and the second tooth 34 mesh with each other. When the elastic member 5 returns to its original position, the first tooth 33 and the second tooth 34 disengage from each other. The locking part 31 includes the first tooth 33, and the mating part 32 includes the second tooth 34.

[0063] In other words, when the door 1 is opened to a predetermined angle and needs to be maintained at that angle, the drive unit 41 drives a local deformation of the elastic member 5, causing it to move closer to the rotating shaft structure 2. At this time, the first tooth 33 on the elastic member 5 meshes with the second tooth 34 on the rotating shaft structure 2. The meshing of the first tooth 33 and the second tooth 34 fixes the door 1 relative to the body 200.

[0064] When the door 1 needs to be rotated, the drive unit 41 moves to partially reset the elastic element 5 so that its corresponding movement moves away from the rotating shaft structure 2. At this time, the first tooth 33 on the elastic element 5 and the second tooth 34 on the rotating shaft structure 2 disengage from each other, so that the door 1 and the body 200 can move relative to each other.

[0065] When the door 1 is held at a predetermined angle, to prevent external force from forcibly rotating the door 1, the force applied to the elastic member 5 causes the elastic member 5 to spring back to its original position, thereby disengaging the first tooth 33 and the second tooth 34 from each other. In one embodiment, please refer to... Figure 9 The pressure angle α of the second tooth 34 is set to be less than 30°. Even if the door 1 is forcibly rotated by external force, the component force applied to the elastic element 5 is relatively small and will not cause the elastic element 5 to spring back to its original position, thus making the locking between the door 1 and the body 200 more stable.

[0066] In one embodiment, the door assembly 100 further includes a support member 6, which is movably disposed on the door body 1 and corresponding to the pivot structure 2. The direction of movement of the support member 6 is the same as the direction of the rotation axis of the door body 1, and a locking part 31 is provided on the support member 6; a corresponding mating part 32 is provided on the pivot structure 2.

[0067] The drive unit 41 includes a cam 411 rotatably mounted on the door body 1. The rotation axis of the cam 411 is intersected with the rotation axis of the door body 1. The peripheral sidewall of the cam 411 is in contact with the end face of the support member 6, so that when the cam 411 rotates to the first position, it drives the support member 6 to move so that its locking part 31 and the engaging part 32 are locked together; when the cam 411 rotates to the second position, it drives the support member 6 to move so that its locking part 31 and the engaging part 32 are disengaged and unlocked.

[0068] Continuing from the above, the door assembly 100 also includes an elastic element 5, which is suspended from the door body 1 and is positioned corresponding to the pivot structure 2. In some application scenarios, the support element 6 is set as the aforementioned elastic element 5.

[0069] In conjunction with the above embodiment in which "the locking part 31 includes a first tooth 33 and the mating part 32 includes a second tooth 34", the locking and unlocking of the door assembly 100 will be further explained.

[0070] In this embodiment, an elastic element 5 is suspended on the door body 1, and a locking part 31 is provided on the elastic element 5. A mating part 32 is provided on the rotating shaft structure 2. A cam 411 is rotatably mounted on the door body 1, and the peripheral sidewall of the cam 411 is in contact with the end face of the elastic element 5. A first tooth 33 is provided on the elastic element 5, and a second tooth 34 is provided on the rotating shaft structure 2.

[0071] Please see Figure 5 and Figure 6 When the cam 411 rotates to the first position, the short side of the cam 411 contacts the elastic element 5, the elastic element 5 partially rebounds and resets, and moves away from the rotating shaft structure 2. At this time, the first tooth 33 on the elastic element 5 and the second tooth 34 on the rotating shaft structure 2 disengage from each other, so that the door body 1 and the body 200 can move relative to each other.

[0072] Please see Figures 7 to 9 When the cam 411 rotates to the second position, the long side of the cam 411 contacts the elastic element 5, causing the elastic element 5 to deform locally and move closer to the rotating shaft structure 2. At this time, the first tooth 33 on the elastic element 5 meshes with the second tooth 34 on the rotating shaft structure 2. The meshing of the first tooth 33 and the second tooth 34 fixes the door body 1 relative to the machine body 200.

[0073] Specifically, the cam 411 has an elliptical cross-section in its axial direction. When the cam 411 rotates to the first position, the surface corresponding to the short axis of the cam 411 contacts the elastic element 5, the elastic element 5 partially springs back to its original position, and the first tooth 33 on the elastic element 5 disengages from the second tooth 34 on the rotating shaft structure 2. When the cam 411 rotates to the second position, the surface corresponding to the long axis of the cam 411 contacts the elastic element 5, the elastic element 5 partially deforms, and the first tooth 33 on the elastic element 5 meshes with the second tooth 34 on the rotating shaft structure 2.

[0074] In one embodiment, please refer to Figure 1 , Figure 5 and Figure 7 The side of the door body 1 is provided with a clearance groove 11 at the position corresponding to the cam 411 so that the cam 411 is exposed. The drive structure 4 also includes a lever 42, one end of which is inserted into the clearance groove 11 and connected to the cam 411, and the other end of which is used for the user to turn.

[0075] Understandably, the front of door 1 typically needs to accommodate core functional areas such as an operation panel, observation window, and handles, while the side space is relatively unused. Placing the clearance groove 11 and lever 42 on the side avoids interfering with the functional layout of the front of door 1, ensuring the integrity and functionality of the door 1's appearance. Simultaneously, the lever 42's side location allows users to operate it by moving it along the side of door 1, conforming to ergonomic habits.

[0076] Furthermore, in this embodiment, the clearance groove 11 on the side of the door 1 not only ensures that the cam 411 is partially exposed, but also provides a side access point for the connection between the lever 42 and the cam 411, so that the installation position of the lever 42 is close to the side of the door 1. Compared with reaching out from the front of the door 1 to operate, side operation is more labor-saving.

[0077] One end of the lever 42 is inserted into the avoidance groove 11 and connected to the cam 411, while the other end is for the user to turn. The user's manual turning of the lever 42 is directly converted into the rotation of the cam 411, which in turn drives the support 6 and the locking part 31 to move. The operating force transmission efficiency is high, and the user can lock or unlock without applying too much force.

[0078] In one embodiment, please refer to Figure 2 , Figure 10 and Figure 11 The door body 1 has a notch 12 on its hinge side with the body 200. The pivot structure 2 includes a frame 21 and a shaft 23. The frame 21 is located on the body 200, and a mounting arm 22 protrudes from the surface of the frame 21 opposite to the body 200. The suspended end of the mounting arm 22 is inserted into the notch 12 and is rotatably connected to the door body 1 through the shaft 23. The locking part 31 protrudes from the periphery of the notch 12, and the mating part 32 is located at the suspended end.

[0079] In this embodiment, the frame 21 is fixed to the body 200, and a mounting arm 22 protrudes from the side of the frame 21 opposite to the body 200. The suspended end of the mounting arm 22 is inserted into the notch 12 and is rotatably connected to the door 1 via the shaft 23. That is, the door 1 rotates relative to the suspended end when it is rotated to open or close.

[0080] In conjunction with the above structure, the door assembly 100 also includes an elastic element 5, which is suspended from the door body 1 and spaced side-by-side with the mounting arm 22 in the height direction F1 of the body 200. In the height direction F1 of the body 200, the two surfaces of the elastic element 5 opposite to its suspended end are respectively provided with a first tooth 33 and a second tooth 34. Simultaneously, a mounting cam 411 is rotated on the door body 1. Thus, by rotating the cam 411, the elastic element 5 can be deformed and reset, allowing the door body 1 and the body 200 to be locked or unlocked.

[0081] To facilitate the assembly of the door assembly 100, in one embodiment, please refer to... Figure 2 The door body 1 includes a first cover 13 and a second cover 14 spliced ​​together in the thickness direction F2 of the body 200. The first cover 13 has a notch 12 at the corresponding hinge side, and the suspended end of the mounting arm 22 is rotatably connected to the first cover 13 via a shaft 23. The second cover 14 is located on the side of the first cover 13 facing away from the body 200. A locking structure 3 is located on the first cover 13 and between the first cover 13 and the second cover 14.

[0082] Based on the above structure, when the cam 411 rotates to the second position, the long axis corresponding surface of the cam 411 contacts the elastic element 5, the elastic element 5 is partially deformed, and the first tooth 33 on the elastic element 5 meshes with the second tooth 34 on the rotating shaft structure 2.

[0083] When the door 1 is held at a predetermined angle, in order to prevent external force from forcibly rotating the door 1, the force applied to the elastic member 5 causes the elastic member 5 to spring back to its original position. In one embodiment, the door assembly 100 also includes a limiting part 7 provided on the door 1, and when the locking part 31 moves to lock into the mating part 32, the limiting part 7 can be limited to the driving structure 4 so that the driving structure 4 is fixed relative to the door 1.

[0084] Continuing from the above, a lever 42 is provided for the user to move, so that the cam 411 rotates. Specifically, the limiting part 7 includes a limiting protrusion 71 protruding from the surface of the door body 1. When the locking part 31 moves to lock into the engaging part 32, the limiting protrusion 71 engages with the lever 42.

[0085] This utility model also provides a garment processing device 1000. Please refer to [link / reference]. Figure 12 The garment processing equipment 1000 includes a body 200 and a door assembly 100 disposed on the body 200. The door 1 is rotatably mounted on the body 200 via a pivot structure 2 on one side. The door 1 can rotate relative to the body 200 to open or close the opening.

[0086] It should be noted that the door assembly 100 is configured as described above, which includes all the technical features of the door assembly 100. Therefore, the clothing processing equipment 1000 also includes all the technical features of the door assembly 100, and thus has the technical effects brought about by all the technical features described above.

[0087] After the garment processing equipment 1000 completes its processing, the user will open the door 1 to allow for heat dissipation or moisture dissipation. The drive unit 41 drives the locking unit 31 to move, causing the locking unit 31 to engage with the mating unit 32. At this time, the door 1 is relatively fixed to the machine body 200, and the door 1 can be maintained at a fixed angle. In this way, not only can the door 1 be prevented from being rotated at will, ensuring that pets cannot enter the processing chamber through the opening, but it can also maintain heat dissipation or moisture dissipation.

[0088] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
