[0042] This application provides a door assembly and a clothes handling device to solve the problem that the inner and outer rings of the door of existing drum washing machines are fixed by multiple screws, which is time-consuming and has low assembly efficiency. The following will be described in conjunction with the accompanying drawings.
[0043] The door assembly provided in this application embodiment is suitable for clothing processing equipment. Please refer to [link / reference]. Figure 1 and Figure 2 The door assembly includes an inner door ring 1 and an outer door ring 2. The inner door ring 1 is provided with a first insertion part 11 and a stop part 12; the outer door ring 2 is provided with a second insertion part 21 and a limiting buckle 22. The outer door ring 2 is used to rotate in a first direction so that the second insertion part 21 is inserted into the first insertion part 11 and the limiting buckle 22 is engaged with the stop part 12. The first insertion part 11 is used to limit the second insertion part 21 in the first direction, and the stop part 12 is used to limit the limiting buckle 22 in the second direction; wherein, the second direction is opposite to the first direction.
[0044] The door assembly provided in this application embodiment connects the outer ring 2 and the inner ring 1 via a first insertion part 11 and a second insertion part 21, thereby limiting the inner ring 1 and the outer ring 2 in a first direction. Simultaneously, a stop part 12 and a limiting buckle 22 further limit the inner ring 1 and the outer ring 2 in a second direction, enabling rapid rotational installation and fixation of the inner ring 1 and the outer ring 2. This method is simple, convenient, and highly efficient in assembly. Compared to assembling the inner ring 1 and the outer ring 2 with multiple screws, production efficiency is significantly improved, material complexity is reduced, the connection is more reliable, and the problem of stripped screws is eliminated.
[0045] Specifically, the first direction can be clockwise rotation of the outer ring 2, and the second direction can be counterclockwise rotation of the outer ring 2. Of course, as an alternative implementation, the first direction can also be counterclockwise rotation of the outer ring 2, and the second direction can be clockwise rotation of the outer ring 2.
[0046] Optionally, please refer to Figure 3 and Figure 4The first insertion part 11 has a slot 111 extending in a first direction. The slot 111 includes a groove opening and a groove bottom wall that are sequentially opposite each other in the first direction. The second insertion part 21 includes a plug extending in the first direction. The plug is used to insert into the slot 111 from the groove opening and abut against the groove bottom wall.
[0047] The inner ring 1 and the outer ring 2 are rotated and fixed by inserting the rod into the slot 111 and simultaneously abutting against the bottom wall of the slot 111. That is, when the outer ring 2 is rotated in the first direction until the rod abuts against the bottom wall of the slot 111, the outer ring 2 and the inner ring 1 are installed in place.
[0048] Optionally, please refer to Figure 6 and Figure 7 The insertion rod can be L-shaped, with one end connected to the outer ring 2 of the door and extending towards the inner ring 1 of the door, and the other end extending along a first direction, wherein the portion extending along the first direction is inserted into the slot 111. Furthermore, the portion extending along the first direction can be interference-fitted with the slot 111 so that the insertion rod and the slot 111 can be inserted and locked together, increasing the connection strength between the insertion rod and the slot 111.
[0049] Optionally, please refer to Figure 9 The outer ring 2 of the door is provided with a receiving hole 23, and a connecting plate 24 is provided inside the receiving hole 23. The connecting plate 24 includes a connecting end and a free end. The connecting end is connected to the hole wall of the receiving hole 23, and the free end extends into the receiving hole 23. A limiting buckle 22 is provided on the side of the connecting plate 24 facing the inner ring 1 of the door. The connecting plate 24 is used to elastically deform when the limiting buckle 22 presses against the stop part 12, and to reset when the limiting buckle 22 engages with the stop part 12. Furthermore, the limiting buckle 22 is also elastic.
[0050] The free end of the connecting plate 24 provides deformation space for the compression of the limiting buckle 22, preventing the limiting buckle 22 and the anti-reverse part 12 from being violently jammed together and causing damage to the limiting buckle 22 or the anti-reverse part 12. At the same time, when it is necessary to disassemble the inner door ring 1 and the outer door ring 2, the free end of the connecting plate 24 can be pried to pry up the limiting buckle 22, so that the limiting buckle 22 and the anti-reverse part 12 are separated from each other, and the limiting effect of the inner door ring 1 and the outer door ring 2 in the second opposite direction is contacted. Then, the outer door ring 2 can be rotated in the second direction to release the insertion limit between the first insertion part 11 and the second insertion part 21, thereby realizing the separation of the inner door ring 1 and the outer door ring 2.
[0051] Optionally, please refer to Figure 3 and Figure 5The anti-reverse part 12 includes a first guide slope 121 and a first limiting surface connected in sequence. The first guide slope 121 gradually approaches the outer ring 2 of the door along a first direction, and the limiting buckle 22 slides along the first guide slope 121 until it abuts against the first limiting surface. Specifically, the anti-reverse part 12 includes a base and an anti-reverse protrusion. The base is disposed on the side of the inner ring 1 facing the outer ring 2, and the anti-reverse protrusion is disposed on the base. The anti-reverse protrusion includes the first guide slope 121 and the first limiting surface connected in sequence, thus forming a protrusion with a gradually decreasing cross-sectional area. The first guide slope 121 and the first limiting surface are arranged in sequence along the first direction. The top of the protrusion is rounded to avoid sharp structures.
[0052] Optionally, the limiting buckle 22 is provided with a second guide slope and a second limiting surface. The second guide slope gradually moves away from the inner ring 1 of the door along a first direction, and slides along the first guide slope 121 so that the second limiting surface abuts against the first limiting surface. Specifically, the limiting buckle 22 includes a protrusion with a gradually decreasing cross-sectional area toward the anti-reverse portion 12.
[0053] Optionally, the first insertion part 11 is provided with a limiting part 112 on the side facing the outer ring 2; the outer ring 2 is also provided with a through hole 25, which is opposite to the first insertion part 11; please refer to Figure 8 The door assembly also includes a pry bar 3, which is used to pry the limiting part 112 along the first direction through the extension hole 25 to separate the first insertion part 11 from the second insertion part 21. To avoid the first insertion part 11 and the second insertion part 21 being too tightly connected, making it difficult to disengage the connection by relative rotation of the inner door ring 1 and the outer door ring, the limiting part 112 and the pry bar 3 are provided. By prying the limiting part 112 on the first insertion part 11 with the pry bar 3, the force on the first insertion part 11 and the second insertion part 21 can be precisely released, so as to easily separate the first insertion part 11 and the second insertion part 21.
[0054] Optionally, the limiting part 112 includes a plurality of limiting protrusions, which are spaced apart on the first insertion part 11. The pry bar 3 can abut against any one of the limiting protrusions to pry the first insertion part 11.
[0055] Optionally, the pry bar 3 includes a hand-held end and a prying end. The cross-sectional area of the prying end gradually decreases in the direction away from the hand-held end, so the force exerted by the prying end on the limiting part 112 is more precisely controlled.
[0056] Optionally, the first plug-in portion 11 and the anti-reverse portion 12 include multiple portions and are spaced apart on the inner ring 1 of the door; the second plug-in portion 21 and the limit buckle 22 respectively include multiple portions and are spaced apart on the outer ring 2 of the door; the first plug-in portion 11 and the second plug-in portion 21 correspond one-to-one, and the anti-reverse portion 12 and the limit buckle 22 correspond one-to-one.
[0057] By setting multiple first insertion parts 11, second insertion parts 21, anti-reverse parts 12, and limit buckles 22, the connection strength between the inner door ring 1 and the outer door ring 2 is increased, improving the reliability of the door assembly. At the same time, installation time is not increased; all the first insertion parts 11 and second insertion parts 21, as well as the anti-reverse parts 12 and limit buckles 22, can be inserted and installed with a single rotation.
[0058] This application embodiment also provides a garment processing device, including the door assembly as described above. The door assembly includes an inner door ring 1 and an outer door ring 2. The inner door ring 1 is provided with a first insertion portion 11 and a stop portion 12; the outer door ring 2 is correspondingly provided with a second insertion portion 21 and a limiting buckle 22. The outer door ring 2 is used to rotate in a first direction so that the second insertion portion 21 is inserted into the first insertion portion 11 and the limiting buckle 22 is engaged with the stop portion 12. The first insertion portion 11 is used to limit the second insertion portion 21 in the first direction, and the stop portion 12 is used to limit the limiting buckle 22 in the second direction; wherein, the second direction is opposite to the first direction.
[0059] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
