Description

[Detailed description of the invention] The present invention consists of a washing tub molded from resin, a concave part for water passage formed on the side wall of the washing tub so as to protrude outwardly and to be elongated in the vertical direction, and this concave part. This invention relates to a washing machine having a partition wall that is removably attached to the side wall of the washing tub from above, and aims to firmly attach the partition wall to the recessed portion.

Fig. 1 shows a general two-tub washing machine, where 1 is the main body of the washing machine, 2 is a washing tank installed in the main body 1, and a dehydration tank 4 has a dehydration basket 3 rotatably installed inside. It is also molded into a single piece of resin.

5 is a dewatering motor that rotationally drives the dewatering basket 3; 6 is a pulsator that is rotatably installed at the inner bottom of the washing tub 2; 10.

11 is a panel section installed at the upper rear part of the main body 1;
It has built-in electrical components such as a time switch.

In the washing machine having the above configuration, conventionally, in order to increase the rinsing efficiency, water injection from the hose support section 12 provided on the panel section 11 can be selectively switched to two stages A and B, upper and lower.

That is, as shown in FIG. 2, a recessed part 13 is formed below the hose support part 12, protruding outward and extending in the vertical direction on the side wall of the washing tub 2, and this recessed part 13
The partition wall 14 is inserted into the side wall portion of the washing tub 2 from above.

This partition wall 14 had a plurality of holes 15 in its lower part, and formed a semicircular tongue part 16 projecting toward the interior center of the washing tub 2 in its upper part.

When the partition wall 14 is attached to the recessed part 13, recessed parts 18 and 18' protruding outward in proximity to the side wall of the washing tub 2 are provided correspondingly on the recessed part 13 side, and A protrusion 17.17' is provided on the opposite side of the tongue portion 16.
The partition wall 14 is inserted from above the washing tub 2, and the protrusion 17, 17' and the recesses 18, 1 of the recess 13 are inserted.
It was attached by engaging with 8'.

However, in such a conventional structure, the concave portion 13 is not restricted from expanding in the direction of the arrow F, and also because the concave portion 13 itself has a slope, it is difficult to pour water or laundry into the washing tub 2. When this happens, a force is applied in the direction of arrow F.

Therefore, the width of the concave portion 13 is subject to repeated loads due to use of the washing machine, and the gap between the concave portion 13 and the partition wall 14 gradually increases.

In addition, this spread in the direction of arrow F increases because when hot water or the like is used as washing water, the strength of the thermoplastic resin washing tub 2 itself is affected and significantly reduced, and depending on the time and number of times of use. , the width of the concave portion 13 also tended to increase.

As a result, in such a conventional example, the concave portion 13 and the partition wall 14
Buttons, pins, etc. could get stuck in the gaps created between the laundry, or clothes could dig into them, damaging the laundry and making the product look unsightly, reducing its value as a product.

The present invention was developed to solve the above-mentioned conventional problems, and an embodiment thereof will be described below with reference to FIGS. 3 and 4.

The partition wall 19 has a tongue part 20 and a washing tub 2 on the opposite side.
1 and a protrusion 22,22' that protrudes outward;
The partition wall 19 has projecting ribs 23 and 23' projecting diagonally outward from the washing tub 21 at both lateral ends thereof.

That is, the protruding ribs 23, 23' have a length such that they protrude slightly outward from the washing tub 21 from the inner wall surface of the washing tub 21, which is indicated by the broken line in FIG.

The degree of protrusion is indicated by 11 in the figure.

The washing tub 21 is connected to the concave portion 24 on the side wall from the partition wall 19.
1 Locking portion 25.2 of the outwardly projecting protrusion 22.22'
Engaging portions 26, 26' are provided to engage with 5'.

On the other hand, the aforementioned protruding ribs 23.23' provided at both lateral ends of the partition wall 19 are connected to the inner wall 27.27' of the washing tub 21.
It comes to be pressure-welded along the

That is, the protruding ribs 23, 23'
．． 27', the ll of the partition wall 19 alone is absorbed, and the protruding ribs 23, 23' are deformed by receiving force from their roots toward the tongue portion 20, and the protruding ribs 23, 23'
The elasticity of the resin material forming the partition wall 19 pushes against the inner wall 27, 27' of the washing tub 21, thereby making the partition wall 19 more firmly attached.

In this state, above 41. is the closing allowance.

Further, the protruding ribs 23, 23' have sufficient length, and a slight gap l' is created at the base of the protruding portion 22, 22' with the inner wall 27, 27' of the washing tub 21, as shown in Fig. 4. There is.

Since these sufficiently long protruding ribs 23, 23' cover the inner wall 27, 27' of the washing tub 21, the width of the concave portion 24 is reduced by repeated loads due to the use of the washing machine or by the use of hot water, etc. Even if it increases a little, it does not create a gap between the concave portion 24 and the partition wall 19.

On the other hand, if the length of the locking portion 25, 25' with the concave portion 24 is sufficiently long, the locking will be sufficient even if the concave portion 24 expands to some extent.

Therefore, as a result, buttons, pins, etc. may become stuck,
Or it may dig into your clothes and damage your laundry.
This does not mean that the value of the product decreases.

In the above embodiment, the installation of the concave portion 24 and the partition wall 19 in the upper and lower two-stage water supply has been described, but the invention can also be applied to the installation of the overflow filter 28 shown in FIG. 1.

As is clear from the above embodiments, the washing machine of the present invention has a concave portion formed on the side wall of the resin washing tub that projects outward and is long in the vertical direction, and a portion of the concave portion on the side wall of the washing tub that extends from above. a removably attached partition wall, and a locking part that engages with an outwardly directed protrusion formed integrally with the partition wall is provided in the recessed part, while at both lateral ends of the partition wall, A protruding rib having elasticity that presses against the inner wall of the washing tub in the engaged state is provided, and the protruding rib has its own elasticity and presses against the inner wall of the washing tub, thereby separating the concave portion and the partition wall. The installation of bulkheads can provide a structure that is strong and resistant to deformation due to load and temperature.
The strength, precision, etc. of installing overflow filters, bulkheads for lower water supply, etc. can be greatly improved, and the occurrence of gaps between the concave portions and the bulkheads can be kept to a minimum due to the elasticity of the protruding ribs. .
