[0038] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0039] See also Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of the door assembly 1 provided in an embodiment of the present application. Figure 2 This is an exploded schematic diagram of the door assembly 1 provided in an embodiment of the present application. Figure 3 for Figure 2 The enlarged schematic diagram of the middle A part, Figure 4 for Figure 2 The enlarged schematic diagram of the middle part B. The door assembly 1 for a washing machine provided in the present application comprises a base 11 , a mask assembly 12 , a swing assembly 13 and a limit assembly 14 .

[0040] The base 11 is provided with a clothing inlet 110, through which clothing can be put into the washing machine. The mask assembly 12 includes a reel 121 and a rolling door cover 122. The reel 121 is rotatably arranged on the base 11. One end of the door cover 122 is connected to the reel 121. The reel 121 can be wound around the door cover 122 to expose at least part of the clothing inlet 110. By pulling the door cover 122, the door cover 122 can also cover at least part of the clothing inlet 110. The door cover 122 can be a flexible component made of any one of sound-absorbing materials such as organic fibers, inorganic fibers, inorganic foams, and foam plastics to absorb the noise generated by the door assembly 1 during use. The rocking assembly 13 includes a rocking rod 131 and a guide rope 132. The rocking rod 131 is arranged opposite to the reel 121 and is rotatably arranged on the base 11. The guide rope 132 connects the rocking rod 131 and the other end of the door cover 122. When the rocking rod 131 rotates, the guide rope 132 can be rolled up to pull the door cover 122 to cover at least part of the clothing delivery opening 110. The limiting assembly 14 includes a first limiting element 141 and a second limiting element 142. The first limiting element 141 is arranged on the reel 121 or the rocking rod 131, and the second limiting element 142 is arranged on the base 11. The first limiting element 141 can be engaged with the second limiting element 142 to prevent the rocking rod 131 or the reel 121 from rotating, thereby allowing the door cover 122 to keep covering at least part of the clothing delivery opening 110.

[0041] Compared with the traditional hinged cover type door body, the rolling door cover provided in the embodiment of the present application can respectively cover and reveal the clothing delivery port 110 by pulling and winding it, which can avoid the problem of fingers being pinched by the door body. In addition, by setting a first limiting element 141 on the rocker 131 or the roller 121, and setting a second limiting element 142 on the base 11, the rocker 131 or the roller 121 cannot roll up the door cover 122 when the first limiting element 141 and the second limiting element 142 are engaged, so that the door cover 122 can keep covering at least part of the clothing delivery port 110, thereby improving the convenience and user experience.

[0042] See also Figure 4 and Figure 5 , Figure 5 for Figure 2 The enlarged schematic diagram of the middle C portion shows the assembly of the coil spring 123 on the winding shaft 121.

[0043] When the first limiting element 141 and the second limiting element 142 of the door assembly provided in the embodiment of the present application are engaged, the rocker 131 or the reel 121 cannot rotate, so that the door cover 122 keeps covering at least part of the clothing delivery opening 110; when the first limiting element 141 and the second limiting element 142 are separated, the reel 121 can rotate and roll up the door cover 122 to expose the clothing delivery opening 110. In order to enable the reel 121 to automatically roll up the door cover 122, the shielding assembly 12 further includes a coil spring 123, which is wound around the end of the reel 121. Preferably, a coil spring 123 can be provided at each end of the reel 121. For each coil spring 123, one end of the coil spring 123 is connected to the reel 121, and the other end of the coil spring 123 is connected to the door cover 122, so as to accumulate force to drive the reel 121 to roll up the door cover 122 during the process of the door cover 122 covering the clothing delivery opening 110.

[0044] Specifically, the reel 121 can rotate in one direction under the influence of the door cover 122. At the same time, the distance between the two adjacent layers of the coil spring 123 gradually decreases. As a result, the coil spring 123 accumulates elastic potential energy and generates a restoring elastic force that can drive the reel 121 to rotate in the opposite direction. For the sake of convenience, this specification refers to the rotation direction of the reel 121 in one direction due to the influence of the door cover 122 as the first rotation direction, and the rotation direction of the reel 121 in the other direction due to the restoring elastic force of the coil spring 123 as the second rotation direction. In the whole process of pulling the door cover 122 to cover at least part of the clothing inlet 110, the first limit Element 141 and the second limiting element 142 always remain in a clamping state to limit the rotational movement of the reel 121 to wind up the door cover 122 in the second rotation direction, so as to ensure that the door cover 122 can cover the clothing inlet 110 at any position. When the traction external force acting on the door cover 122 is cancelled and the first limiting element 141 and the second limiting element 142 are separated, the reel 121 will rotate in the second rotation direction to wind up the door cover 122 under the action of the restoring elastic force of the coil spring 123. The door cover 122 is wound around the reel 121 under the rotation of the reel 121, thereby preventing hands from being pinched and improving the convenience and user experience.

[0045] In the embodiment where the first limiting element 141 is arranged on the rocking arm 131, when the door cover 122 covers at least a portion of the clothing loading port 110 and the first limiting element 141 and the second limiting element 142 are engaged, the reel 121 has a tendency to rotate in the second rotation direction under the action of the return elastic force generated by the coil spring 123, and the movement tendency of the reel 121 is transmitted to the rocking arm 131 through the guide rope 132 connected between the reel 121 and the rocking arm 131 and the door cover 122. Since the rotation of the first limiting element 141 fixed to the rocking arm 131 is restricted by the second limiting element 142, the rocking arm 131 is indirectly unable to rotate in the second rotation direction. Rotation occurs, so the movement trend of the reel 121 can make the guide rope 132 and the door cover 122 in a tensioned state, so that at least part of the door cover 122 can better maintain the cover at least part of the clothing delivery port 110. When the first limiting element 141 and the second limiting element 142 are separated, since the first limiting element 141 is no longer constrained by the second limiting element 142, the restoring elastic force of the coil spring 123 can drive the reel 121 to rotate in the second rotation direction to wind up the door cover 122. At the same time, the door cover 122 pulls the guide rope 132 to rotate the rocker 131 until the coil spring 123 releases all its elastic potential energy, and finally the clothing delivery port 110 is exposed. As for the embodiment in which the first limiting element 141 is disposed on the reel 121, when the door cover 122 covers at least a portion of the clothing inlet 110 and the first limiting element 141 and the second limiting element 142 are engaged, the reel 121 has a tendency to rotate in the second rotation direction under the action of the return elastic force generated by the coil spring 123. Since the rotation of the first limiting element 141 fixed to the reel 121 is restricted by the second limiting element 142, the reel 121 cannot rotate in the second rotation direction. The first limiting element 141 and the second limiting element 142 are separated from each other, and since the first limiting element 141 is no longer constrained by the second limiting element 142, the restoring elastic force of the coil spring 123 can drive the reel 121 to rotate in the second rotation direction to wind up the door cover 122. At the same time, the door cover 122 pulls the guide rope 132 to rotate the rocker 131 until the coil spring 123 releases all its elastic potential energy.

[0046] See also Figure 4As an optional embodiment, the first limiting element 141 may include a ratchet, and the second limiting element 142 may include a pawl, wherein the ratchet is fixed to the rocker 131 or the reel 121, and ratchet teeth 1411 are evenly distributed around the periphery of the ratchet. One end of the pawl is rotatably disposed on the base 11, and the other end of the pawl can slide relative to the ratchet teeth 1411 and abut against the ratchet teeth 1411. Specifically, for each ratchet tooth 1411 of the ratchet wheel, the ratchet tooth 1411 may include a sliding surface 1410 and a limiting surface 1420, wherein the sliding surface 1410 extends along the rotation direction of the ratchet wheel, and the limiting surface 1420 is connected to one end of the sliding surface 1410. For each two adjacent ratchet teeth 1411, one end of the sliding surface 1410 of one ratchet tooth 1411 is connected to its limiting surface 1420 and the other end is connected to the limiting surface 1420 of the other ratchet tooth 1411. For the pawl, one end of the pawl can be elastically connected to the base 11 using a spring, so that the other end of the pawl separated from the base 11 can elastically abut against the surface of the ratchet tooth 1411 without being subjected to other external forces. In addition, the pawl can also be provided with a limiting structure, which can enable the pawl to rotate only in the second rotation direction but not in the first rotation direction. Rotation, thereby, when the first limiting element 141 and the second limiting element 142 are mutually engaged, the limiting surface 1420 of the ratchet 1411 and the end of the pawl separated from the base 11 abut against each other under the action of the restoring elastic force of the coil spring 123, and then the rotation of the reel 121 in the second rotation direction is restricted, and finally the door cover 122 can keep covering at least part of the clothing inlet 110 even in the absence of the constraint of external traction force, and when the rocker 131 is rotated to make the guide rope 132 pull the door cover 122 to cover at least part of the clothing inlet 110, the rocker 131 or the reel 121 can drive the ratchet to rotate in the first rotation direction, and the end of the pawl separated from the base 11 can make relative sliding motion on each sliding surface 1410 of the ratchet in turn, so as to pull the door cover 122 to cover at least part of the clothing inlet 110.

[0047] See also Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the structure of one side of a limit assembly 14 provided in another embodiment of the present application. Figure 7This is a schematic diagram of the structure of the other side of the limiting assembly 14 provided in another embodiment of the present application. As an optional implementation, the first limiting element 141 includes a first limiting wheel, and the second limiting element 142 includes a second limiting wheel; the first limiting wheel and the second limiting wheel are opposite, and the end surface of the first limiting wheel facing the second limiting wheel is provided with a first limiting structure 1412, and the end surface of the second limiting wheel facing the first limiting wheel is provided with a second limiting structure 1422, and the first limiting structure 1412 can rotate relative to the second limiting structure 1422 and abut against the second limiting structure 1422. Exemplarily, one of the first limiting structure 1412 and the second limiting structure 1422 can be a limiting protrusion, and the other can be a limiting slide groove. This specification takes the first limiting structure 1412 as a limiting protrusion provided on the first limiting wheel and the second limiting structure 1422 as a limiting slide groove provided on the second limiting wheel as an example for schematic description. Specifically, the first limiting wheel can be fixed to the end surface of the rocker 131 or the scroll 121, and the second limiting wheel can be fixed to the base 11. The first limiting wheel is moved toward the end surface of the second limiting wheel along the first limiting wheel. A plurality of limiting protrusions are evenly distributed in the rotation direction of a limiting wheel, and each limiting protrusion includes a sliding surface 1410 and a limiting surface 1420, wherein the sliding surface 1410 extends along the rotation direction of the first limiting wheel, and the limiting surface 1420 is connected to one end of the sliding surface 1410. Corresponding to the plurality of limiting protrusions of the first limiting wheel, the end surface of the second limiting wheel facing the first limiting wheel is evenly distributed with a plurality of limiting grooves along the rotation direction of the first limiting wheel, and each limiting groove also includes a sliding surface 1410 and a limiting surface 1420. When the first limiting element 141 and the second limiting element 142 are engaged with each other, each limiting protrusion is correspondingly assembled in each limiting slide groove, the sliding surface 1410 of the limiting protrusion is opposite to the sliding surface 1410 of the limiting slide groove, and the limiting surface 1420 of the limiting protrusion and the limiting surface 1420 of the limiting slide groove are in contact with each other under the action of the return elastic force of the coil spring 123, so that the rotation of the reel 121 in the second rotation direction is restricted, and finally the door cover 122 can be moved even without the traction external force. In the constrained state, at least a portion of the clothing loading opening 110 can be kept covered. When the rocker 131 is rotated to make the guide rope 132 pull the door cover 122 to cover at least a portion of the clothing loading opening 110, the rocker 131 or the reel 121 can drive the first limiting wheel to rotate in the first rotation direction, and the sliding surface 1410 of each limiting protrusion can slide relative to the sliding surface 1410 of each limiting slide groove in turn, so as to pull the door cover 122 to cover at least a portion of the clothing loading opening 110.

[0048] Figure 8A schematic diagram of the structure of the limiting assembly 14 provided for another embodiment of the present application. As an optional embodiment, the first limiting structure 1412 and the second limiting structure 1422 can both be limiting teeth. Specifically, a plurality of limiting teeth are evenly distributed along the rotation direction of the first limiting wheel on the end face of the first limiting wheel facing the second limiting wheel, and each limiting tooth includes a sliding surface 1410 and a limiting surface 1420, wherein the sliding surface 1410 extends along the rotation direction of the first limiting wheel, and the limiting surface 1420 is connected to one end of the sliding surface 1410, and the second limiting wheel is also provided with a plurality of limiting teeth corresponding to the plurality of limiting teeth of the first limiting wheel. It can be understood that the limiting teeth of the second limiting wheel and the limiting teeth of the first limiting wheel can be the same in terms of number, shape, geometric parameters and other features. When the first limiting element 141 is engaged with the second limiting element 142, each limiting tooth of the first limiting wheel is correspondingly engaged with each limiting tooth of the second limiting wheel, each sliding surface 1410 of the first limiting wheel is opposite to each sliding surface 1410 of the second limiting wheel, and each limiting surface 1420 of the first limiting wheel is in contact with each limiting surface 1420 of the second limiting wheel under the action of the return elastic force of the coil spring 123, so that the rotation of the winding shaft 121 in the second rotation direction is restricted, and finally the door cover 121 is Even in the state without the restraint of the external pulling force, at least a part of the clothing loading opening 110 can be kept covered. When the rocker 131 is rotated to make the guide rope 132 pull the door cover 122 to cover at least a part of the clothing loading opening 110, the rocker 131 or the reel 121 can drive the first limiting wheel to rotate in the first rotation direction, and each sliding surface 1410 of the first limiting wheel can slide relative to each sliding surface 1410 of the second limiting wheel in sequence, so as to pull the door cover 122 to cover at least a part of the clothing loading opening 110.

[0049] See also Figure 3The rocking assembly 13 may further include a reset element 134, which is used to elastically connect the base 11 and the first limiting element 141, and the elastic element is configured to generate an elastic reset force for driving the first limiting element 141 to approach the second limiting element 142 when the first limiting element 141 is away from the second limiting element 142. Specifically, the reset element 134 can be a spring. In an embodiment in which the first limiting element 141 is fixed to the rocking arm 131, the spring can be connected between the rocking arm 131 and the base 11, so that the first limiting element 141 is indirectly elastically connected to the base 11. When an external force is applied to cause the rocking arm 131 to move axially in one direction, the first limiting element 141 moves away from the second limiting element 142. At this time, the reel 121 can be wound around the door cover 122 and drive the rocking arm 131 to rotate through the connected door cover 122 and the guide rope 132. At the same time, the spring will generate a reset force due to being compressed or stretched. When the external force acting on the rocking arm 131 is removed, the rocking arm 131 moves axially in the other direction driven by the spring reset force, and the first limiting element 141 approaches the second limiting element 142 until it is re-engaged. Similarly, in the embodiment where the first limiting element 141 is fixed to the reel 121, the spring can be connected between the reel 121 and the base 11, so that the first limiting element 141 is indirectly elastically connected to the base 11. When an external force is applied to cause the reel 121 to move axially in one direction, the first limiting element 141 moves away from the second limiting element 142. At this time, the reel 121 can be wound around the door cover 122. At the same time, the spring will generate a restoring force due to being compressed or stretched. When the external force acting on the reel 121 is removed, the reel 121 moves axially in the other direction driven by the restoring force of the spring, and the first limiting element 141 approaches the second limiting element 142 until it is re-engaged.

[0050] See also Figure 3 and Fig. 9 , Fig. 9 for Figure 2 Enlarged schematic diagram of the middle D part. In some embodiments, a guide groove 111 may be provided on the side of the base 11 facing the door cover 122, and the guide groove 111 is extended along the movement direction of the door cover 122. Correspondingly, a roller 124 may be provided on the side of the door cover 122 facing the base 11, and the roller 124 is rollingly assembled in the guide groove 111. A rolling fit is formed between the roller 124 and the guide sleeve, thereby greatly reducing the friction between the door cover 122 and the base 11. When the door cover 122 is pulled to cover at least part of the clothing inlet 110, and the reel 121 rotates and winds the door cover 122, the jamming between the door cover 122 and the base 11 can be effectively reduced. It is understandable that in some embodiments, replacing the roller 124 provided on the door cover 122 with a ball can also achieve the same technical effect.

[0051] In some embodiments, the door assembly 1 further includes a motor (not shown) mounted on the base 11, and the motor is connected to the rocker 131 to drive the rocker 131 to rotate. Specifically, the door assembly 1 further includes a control system, and the motor can be electrically connected to the control system. The control system includes a control panel provided on the base 11, and the control panel is used for the operator to input a response signal for controlling the motor to rotate and stop. Thus, the operator can control the motor by operating the control panel, and finally achieve the purpose of driving the rocker 131 to rotate by the motor to pull the door cover 122 to cover at least part of the clothing delivery port 110, thereby improving the intelligence of use.

[0052] See also Fig.10 , Fig.10 The structural diagram of the washing machine 100 provided in the embodiment of the present application is shown in FIG. The washing machine 100 comprises a washing tub and a door assembly 1 provided in the embodiment of the present application, wherein the washing tub is provided with a clothing receiving cavity, and a clothing loading port 110 of the door assembly 1 is connected to the clothing receiving cavity.

[0053] In order to facilitate those skilled in the art to better understand the implementation methods of the embodiments of the present application, the operation process of the washing machine in one embodiment of the present application is schematically described as follows in combination with a specific usage scenario.

[0054] First, put the clothes to be processed into the clothes holding chamber from the clothes feeding port, then, turn the rocker to pull the door cover to cover the clothes feeding port, and stop turning the rocker after the door cover completely covers the clothes feeding port. When the clothes need to be taken out, first press the rocker axially to move the first limiting element away from the second limiting element, and then the reel automatically winds up the door cover under the action of the winding spring, and the clothes feeding port is completely exposed and the clothes can be taken out.
