Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 3, the drain pipe assembly of the present embodiment includes a drain pipe 100 and a hook 200, wherein the drain pipe 100 is a circular pipe, and includes a pipe portion 110 and a water outlet head portion 120 located at a water outlet end of the pipe portion 110, the water outlet head portion 120 and the pipe portion 110 are generally an integrally formed structure, a water inlet of the pipe portion 110 of the drain pipe 100 is used for being connected with a water outlet of an outer tub of a washing machine, and the hook 200 is installed on the water outlet head portion 120 of the drain pipe 100; the water outlet head 120 of the present embodiment includes a second pipe segment 121, a first pipe segment 122, and a constricted pipe segment 123 located between the second pipe segment 121 and the first pipe segment 122, which are sequentially arranged along a water discharge direction (as shown by a horizontal arrow in fig. 1), the hook 200 includes a sleeve portion 210 and a hook portion 220, the hook portion 220 is fixedly connected to an outer wall of the sleeve portion 210, the sleeve portion 210 is sleeved on the constricted pipe segment 123, and one end of the sleeve portion 210 abuts against a first transition end surface a of the first tube section 122 and the neck section 123, that is, a step surface at a transition between the first tube section 122 and the neck section 123, and the other end abuts against a second transition end surface B of the neck section 123 and the second tube section 121, that is, a step surface at a transition between the neck section 123 and the second tube section 121, that is, the sleeve portion 210 is engaged with the neck section 123 to limit the axial direction of the sleeve portion 210 and prevent the sleeve portion from coming off the outlet head 120 of the drain pipe 100.

In the drain pipe assembly of the present embodiment, the specific assembly process of the hook 200 and the drain pipe 100 is shown in fig. 4 and 5, and the hook 200 is pushed through the first pipe section 122 of the water outlet head 120 of the drain pipe 100 in the direction opposite to the drainage direction (as shown by the horizontal arrow in fig. 4 and 5) until it is pushed onto the neck section 123, so that the sleeve portion 210 is clamped in the neck section 123, and the hook 200 is mounted on the drain pipe 100.

To reduce the amount of circumferential movement of the hanger 200, the neck segment 123 includes a first portion 123A and a second portion 123B connected, the first portion 123A having an outer diameter less than the outer diameter of the second portion 123B, the first portion 123A being coaxially connected to the first segment 122, the second portion 123B being connected to the second segment 121; the sleeve portion 210 comprises a tapered portion 211 corresponding to the first portion 123A and a straight portion 212 corresponding to the second portion 123B, the tapered portion 211 and the straight portion 212 are coaxially connected into a whole, the inner diameter of the tapered portion 211 is smaller than the inner diameter of the straight portion 212 and smaller than the outer diameter of the first pipe section 122, the free end of the sleeve portion 210 on the tapered portion 211 side is in a reduced mouth shape, and the straight portion 212 and the second portion 123B are sleeved in a matched mode. Thus, in the initial stage of installing the hook 200, as shown in fig. 4, the first pipe section 122 extrudes the tapered portion 211 to cause the tapered portion 211 to generate elastic deformation radially outward until the tapered portion is pushed to the first portion 123A of the necking pipe section 123, and meanwhile, the straight cylinder portion 212 is fittingly sleeved on the second portion 123B, so that the circumferential movement of the hook 200 is small, and the hook 200 can keep some circumferential movement and can rotate along the drain pipe, so that the hook portion 220 of the hook can be hung conveniently.

Further, in order to facilitate the elastic deformation of the tapered portion 211, as shown in fig. 1 and 3, a plurality of slits 213 are formed in the tapered portion 211 and arranged along the circumferential direction thereof, so that the tapered portion 211 is divided into a plurality of arc-shaped pieces, and the slits 213 provide a space for the elastic deformation of the tapered portion 211.

The hook 220 is attached to the outer wall of the straight tube portion 212 so as not to affect the elastic deformation of the tapered portion 211.

In addition, the inner diameter of the straight cylinder part 212 is smaller than the outer diameter of the second pipe section 121, so that the straight cylinder part 212 is clamped on the necking pipe section 123.

To facilitate the nesting of the tapered portion 211, a transition pipe segment 124 is formed at the free end of the first pipe segment 122, the outer diameter of the transition pipe segment 124 is smaller than the outer diameter of the first pipe segment 122, and the junction 125 of the transition pipe segment 124 and the first pipe segment 122 is tapered. Since the inner diameter of the tapered portion 211 is smaller than the outer diameter of the first pipe section 122, when the tapered portion 211 is sleeved on the first pipe section 122, the friction force is inevitably large, and in order to improve the problem, the passing pipe section 124 and the tapered connecting portion 125 are provided as a supplementary part of the first pipe section 122, so that the length of the first pipe section 122 can be properly reduced, and the friction distance in the process of sleeving the tapered portion 211 is reduced.

The drain pipe 100 in this embodiment is preferably an integrally formed structure to improve the strength of the whole structure, and similarly, the hook 200 is an integrally formed structure.

This embodiment has still proposed a washing machine, and the concrete structure of its drain pipe subassembly refers to the description of the embodiment of the utility model drain pipe subassembly and attached fig. 1 to 5, and no longer repeated description here.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
