Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an improvement in stacking W tanks when transporting a two-tank body (hereinafter referred to as W tank) of a washing machine consisting of a washing tank and a dehydration tank.

[Prior art]

When transporting the double tanks of a washing machine, stacking the double tanks alone will cause them to fall over, so the double tanks are stacked in four tiers, placed against wooden frames from both sides, and tied with string for transportation.

[Purpose of the invention]

The present invention provides a stacking stopper on the tank side wall so that the W tanks do not fall over when stacked, and this stopper hits the other shelf when stacking to prevent the W tanks from falling over. The aim is to achieve wide-ranging cost reductions.

Furthermore, the deformation of the partition plates, which was conventionally supported at the upper end of the partition plates during stacking, is supported by the stopper, thereby eliminating deformation of the partition plates and reducing defects.

[Summary of the invention]

The present invention is characterized in that a stacking stopper is provided on the side wall of the tank.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.
In the figure, a W tank 3 is integrally formed from a washing tank 1 and a dehydration tank 2.

A hole 4 for attaching a pulsator (not shown) and a drain port 5 are provided at the bottom of the washing tank 1.

The bottom of the dehydration tank 2 is provided with a hole 6 for attaching a bellows (not shown) that supports the shaft of the dehydration basket (not shown), and the upper part is provided with a hole 6 for attaching a panel base and an inner lid (not shown). Shelves 7, 7' are provided.

Stacking stoppers 8, 8' are provided on the side walls of the dehydration tank 2 below the shelves 7, 7'.

The lower sides of the stoppers 8 and 8' are flat,
It protrudes by L from the side wall.

When these stoppers 8, 8' are stacked, the flat portions of the stoppers 8, 8' engage with the shelves 7, 7' to ensure stability during stacking.

Since the stoppers 8 and 8' are undercuts, the mold cannot normally be removed, but by first removing the core mold and making the inside of the tank hollow, and then removing the cavity mold in a state that makes it easy to deform, the stoppers can be removed. 8 and 8' were deformed as shown by the dashed lines in FIG. 3 so that they could be molded.

The joint between the washing tank 1 and the dehydration tank 2 is the partition plate 9.
The bottom side has a groove 1 into which the partition plate 9 is inserted when stacking.
0, and the depth of this groove 10 is the same as that of the partition plate 9 when stacking.
It is deep enough so that the top edge of the hole does not touch it.

A W tank flange 11 is integrally provided on the upper part.

4 and 5 show conventional embodiments.

In the figure, a vertical stopper during stacking is provided by a partition plate 9', and to prevent it from falling down, the W tank flange 11' is held down by wooden frames 12 from both sides, and the wooden frames are tied and fixed with strings or the like.

In the above configuration, after the W tanks 3 are formed, by stacking them one after another, the inner and outer walls of the upper and lower W tanks 3 are engaged, and the stoppers 8, 8'
are in contact with the shelves 7 and 7', respectively, and can be stacked in a stable state.

At this time, the upper end of the partition plate 9 is kept from touching the groove 10 to prevent the partition plate 9 from being deformed and resulting in poor assembly during assembly.

Furthermore, since no excessive force is applied when stacking, the W tank flange 11 does not become deformed or loosened, and the number of defects is reduced.

This stack is stacked in five stages, with the W tank flange 11 side facing down, and then placed on a trolley and transported as is.

However, conventionally, when stacking W tanks 3, wooden frame 1
2 will damage the W tank flange 11',
Cover the W tank flange 11' with a cloth to prevent scratches,
Next, place the stacked W tanks 3 on the fallen wooden frame 12,
The other wooden frame 12 is placed on top of the wooden frame 12, and both wooden frames 12 are tied together with string to complete the process and then transported.

In addition, since the stopper in the height direction was performed by the partition plate 9' when stacking, the upper end of the partition plate 9' was sometimes deformed, resulting in assembly failure.

〔Effect of the invention〕

As described above, according to the present invention, the following actions and effects can be expected.

(1) When multiple two-tank bodies are stacked, the outer surface of the side wall of the upper two-tank body is joined to the inner side wall of the lower two-tank body, and the stacking stopper of the upper two-tank body is connected to the inner surface of the side wall of the lower two-tank body. Since it abuts against the shelf of the tank bodies, a large number of two-tank bodies can be stacked in a stable state without using conventional stacking tools such as wooden frames and strings.

(2) When a plurality of two-tank bodies are stacked, the upper end of the partition plate of the lower two-tank body does not come into contact with the upper part of the groove of the upper two-tank body, so the partition plate will not be deformed or damaged.

(3) The stopper is formed as an undercut on the outer surface of the side wall of the dehydration tank, but by removing the mold inside the dehydration tank and then removing the outside mold, the outer wall itself can be removed. Since it bends inward, the mold can be removed. In other words, even though an undercut stopper is provided, a two-tub body can be formed without using a complicated mold such as a slide core.

(4) Since the stopper is partially installed on the outer surface of the side wall of the dehydration tank at a position facing the groove, there is almost no increase in material and no strings are formed on the inner surface of the dehydration tank due to the synthetic resin molding.
