The washing container 200 according to the embodiment of the present invention includes: a container body and a first drain 210. The bottom wall of the container body is provided with a mounting opening 230, the output shaft 610 of the clutch 600 penetrates through the mounting opening 230, namely the container body is sleeved on the periphery of the output shaft 610 of the clutch 600, and the container body keeps static in the running process of the output shaft 610 of the clutch 600. By providing the first drain port 210 in the bottom wall of the tank body and draining water through the first drain port 210, drainage can be achieved without providing the intermediate drain clutch 600 for the washing tank 200 and without using a drain passage in the intermediate drain clutch 600, that is, without providing the washing tank 200 with the ordinary clutch 600. Since the clutch 600 having the drain passage inside is not required to be disposed, it is advantageous to reduce the manufacturing cost of the washing apparatus 1 to which the washing container 200 is applied. Moreover, the output shaft 610 of the clutch 600 is engaged with the mounting port 230, and the mounting port 230 and the first drain port 210 are independent from each other, so that the torque transmission function of the clutch 600 and the drain function of the washing container 200 are independent from each other, and are not restricted from each other, thereby effectively avoiding the mutual influence between the two. In addition, the first drain port 210 is located at least one side of the mounting port 230, and the structure is compact.

In some embodiments, as shown in fig. 6, the first drain port 210 is disposed at the outer periphery of the mounting port 230.

In these embodiments, the first drainage port 210 is disposed at the periphery of the mounting port 230, for example, distributed circumferentially around the central axis of the mounting port 230, so as to facilitate drainage of liquid from multiple directions to the first drainage port 210, and avoid a large amount of liquid remaining on the container body. Moreover, since the first drain port 210 is disposed at the outer circumference of the mounting port 230 and the first drain port 210 is disposed near the mounting port 230, the structure is compact and the structure of the washing container 200 is simplified.

In a particular embodiment, the first drain opening 210 is annular and is circumferentially and continuously distributed about the mounting opening 230. The first drainage port 210 is facilitated to flow from a plurality of directions, drainage is facilitated, and liquid residue is avoided.

In some embodiments, as shown in fig. 2, 4, 5, and 39, the washing container 200 further comprises: the first sealing member 400 is disposed on an inner surface of the bottom wall of the container body, and the first sealing member 400 is located at an outer periphery of the first drain port 210 while avoiding the first drain port 210.

In these embodiments, the first sealing member 400 is disposed on the inner surface of the bottom wall of the container body, so that the first sealing member 400 surrounds the periphery of the first drainage port 210 and avoids the position of the first drainage port 210, that is, the first sealing member 400 neither shields the first drainage port 210, but also intercepts liquid from leaking from the outer side of the first drainage port 210. The liquid is advantageously introduced into the first drain opening 210 through the closed flow path and then discharged. The liquid is prevented from leaking out and not flowing to the first drain port 210 accurately, and the liquid is prevented from leaking to other places and corroding the washing container 200. Especially in the case that the washing container 200 is connected with the washing inner tub 100, etc., the washing inner tub 100 may be hermetically connected by the first sealing member 400, so that the liquid can be discharged through the first drain port 210 without leaking through the gap between the washing container 200 and the washing inner tub 100.

Note that the first seal 400 is located on the outer periphery of the first drain port 210, which means that the first seal 400 is disposed outside the outer edge of the first drain port 210. In the case where the first drain port 210 is provided at the outer periphery of the mounting port 230, that is, in the case where the first drain port 210 is located outside the outer edge of the mounting port 230, the first seal 400 is provided at a side of the first drain port 210 away from the mounting port 230. The first drain port 210 is located at a position inside the first seal 400 which is continuously arranged end to end. In particular, in case the first drain opening 210 is a non-profiled bore, e.g. the first drain opening 210 is an annular opening, a square opening, etc., the first seal 400 may be circumferentially distributed around the central axis of the first drain opening 210.

In a specific embodiment, the first drain opening 210 has a ring shape and is disposed at an outer circumference of the mounting opening 230. The first seal 400 is annular and is disposed on the outer circumference of the first drain port 210.

In another specific embodiment, the first drain opening 210 is provided in a plurality, spaced circumferentially around the central axis of the mounting opening 230, and located at the periphery of the mounting opening 230. The first seal 400 is annular and is disposed on a side of the plurality of first drain ports 210 away from the mounting port 230.

In another specific embodiment, the first drain opening 210 is provided in a plurality, spaced circumferentially around the central axis of the mounting opening 230, and located at the periphery of the mounting opening 230. The number of the first seals 400 is plural, and each of the first seals 400 is disposed at an outer circumference of the at least one first drain hole 210, i.e., is continuously distributed around the at least one first drain hole 210.

In some embodiments, as shown in fig. 9 and 10, the bottom wall of the container body is provided with a mounting groove 220, and the first sealing member 400 is provided to the mounting groove 220.

In these embodiments, the first sealing member 400 is disposed in the mounting groove 220 by providing the mounting groove 220 at the bottom wall of the washing container 200. On one hand, the first sealing element 400 is provided with an installation space, so that the first sealing element 400 is convenient to install in place quickly; on the other hand, the stable connection between the first sealing member 400 and the washing container 200 is facilitated, and the first sealing member 400 is prevented from falling off from the washing container 200 to affect the sealing effect.

In some embodiments, the first seal 400 is an interference fit with the mounting groove 220.

In these embodiments, the first sealing member 400 is interference-fitted to the mounting groove 220, ensuring a stable connection of the sealing member to the washing container 200 while ensuring a sealing effect. Specifically, when the washing container 200 is draining, the interference fit enables liquid to be drained through the first drainage port 210 and not to flow into the mounting groove 220, so that the liquid is prevented from depositing in the mounting groove 220 to pollute and corrode the mounting groove 220 and other parts, and the use of the washing container 200 is prevented from being influenced.

Example two:

on the basis of the first embodiment, the first sealing element 400 is used to cooperate with the component to be rotated to form a dynamic seal.

In some embodiments, the first sealing member 400 cooperates with the member to be rotated to form a dynamic seal, thereby facilitating the washing container 200 to wash laundry or spin the laundry.

In addition, by using the first sealing member 400 for sealing with the member to be rotated in a dynamic sealing manner, in combination with the fact that the member to be rotated can rotate relative to the washing container 200, the member to be rotated maintains a good sealing state with the first sealing member 400 along with the rotation of the member to be rotated. The sealing effect between the to-be-rotated piece and the washing container 200 is favorably ensured, and the phenomenon that liquid enters a control part of the washing equipment 1 to influence the normal operation of the washing equipment 1 and damage the washing equipment 1 due to the fact that the liquid leaks out through a gap between the to-be-rotated piece and the washing container 200 in the operation of spin-drying and the like of the washing container 200 is avoided. It is advantageous to ensure that liquid is discharged through the first drain 210.

In a specific application, since the member to be rotated and the first sealing member 400 belong to a dynamic seal, a high coaxiality is required between the two members. In order to solve this problem, the first sealing member 400 and the to-be-rotated member may be both positioned with respect to the output shaft 610 of the clutch 600, so that the coaxiality of the first sealing member 400 and the to-be-rotated member can be well ensured, thereby solving the problem that the first sealing member 400 is not durable or easily leaks water due to poor coaxiality.

In a specific application, the member to be rotated may be a sealing rib 310 on the connecting member 300.

In some embodiments, the first seal 400 comprises an oil seal; and/or a lip seal structure is provided on one side of the first seal 400 facing the central axis of the first drain port 210; and/or the first sealing member 400 includes a plastic steel frame and an elastic part coated on an outer surface of the plastic steel frame.

In these embodiments, the first sealing element 400 is designed to include an oil seal, which provides a good sealing effect.

By providing the first sealing member 400 with a lip seal structure on the side facing the central axis of the first drain port 210, on the one hand, stable dynamic sealing with the member to be rotated can be achieved; on the other hand, the sliding friction force between the two parts can be greatly reduced, so that the model selection power of the motor for driving the part to be rotated to rotate is reduced.
