Description

[Detailed Description of the Invention] This invention relates to an electric washing machine equipped with a washing water drain pump, and particularly to the structure of a drain discharge pipe provided on the base thereof.

In this type of electric washing machine, Fig. 1 and Fig. 2
As shown in FIG. It is being In this case, an L-shaped elbow pipe is used as the drain discharge pipe 4, and this elbow pipe is screwed to the lower surface of the bottom wall 6 of the base 2 by means of a mounting piece 5. This drain discharge pipe 4 is normally closed with a cap 7 made of rubber or the like, but the cap 7 is connected to the drain discharge pipe 4 via a cap holder 8 to prevent powder from being lost.
It is hung on a pillar-shaped hook 9 planted in the.

However, in the conventional structure described above, the drain discharge pipe 4 is constructed as a separate component, which is costly, and the drain discharge pipe 4 is fixed with screws, which requires an extra number of assembly steps.

Therefore, the purpose of this invention was to create a drain discharge pipe,
To provide an electric washing machine having a simple structure and good assembly workability by integrally forming a hook for locking a cap holder on a base.

An embodiment of this invention will be described below with reference to FIGS. 3 and 4. Note that the same parts as in FIGS. 1 and 2 are indicated by the same symbols.

Referring to FIGS. 3 and 4, the electric washing machine according to the invention has a base 2 made of synthetic resin that supports an outer box (not shown), and is close to the peripheral wall 10 of the bottom wall 6 of the base 2. A cylindrical surrounding wall 11 is formed in the portion where the cylindrical wall 11 is formed. A bottom wall 6 is placed in the center of this surrounding wall 11.
A drain discharge pipe 4' is integrally molded so as to pass vertically through the drain discharge pipe 4', and a cap 7 is inserted into the opening at the lower end of the drain discharge pipe 4'. Further, an opening 12 is provided in a part of the bottom wall 6 near the drain discharge pipe 4', and this opening 12 is provided from the outer periphery of the drain discharge pipe 4'.
A hook 9' is formed so as to face inward, and the tip thereof is bent upward into an L-shape. Thereby, when the hook 9' is inserted into the retaining ring 13 formed at the end of the cap holder 8, it is prevented from easily coming off.

As is clear from the description of the embodiments described above, according to this invention, the drain discharge pipe and the hook for holding the cap holder are integrally molded with the base, so the number of parts is reduced, and the installation of the drain discharge pipe is simplified. The process can be omitted. Furthermore, the cap holder can be hung on the hook with a simple operation. Furthermore, in this invention, the drain pipe is particularly provided on the bottom wall, which simplifies the design of the mold compared to, for example, providing it on the peripheral wall of the base, and is advantageous in terms of cost.
