Description

[Detailed explanation of the idea] The present invention relates to a dehydrating and washing machine.

More specifically, in a case where the outer box is composed of an upper box and a lower box, this refers to a part of the suspension rod that is integrally provided on the lower surface of the bottom plate of the upper box and is used for elastically suspending the rotating device. It is.

A dehydrating and dehydrating washing machine surrounds the outer periphery of the washing tub with a dehydrating tank,
Furthermore, the outer periphery was surrounded by an outer box, but in order to eliminate the need to use the outer box as a dehydration receiving tank, there is one in which the outer box is divided into an upper box and a lower box.

This is done by installing a dehydration tank that also serves as a leakage tank in the upper box, and
A rotating device is provided to rotate the dewatering/dehydrating tank during dehydration and a stirring blade during washing, and a suspension device is provided to elastically suspend the rotating device.

In the above-mentioned dehydrating and washing machine, the outer box is divided into an upper box and a lower box, that is, the upper box is also used as a dewatering tank for receiving waste water, so that a suspension system that elastically suspends the rotating device is created. The problem was how to configure the support for the device's hanging rod.

In the first conventional example of this receiver, in order to make it completely waterproof, the bottom plate of the upper box is not processed at all, and there is a separate part between the bottom plate of the upper box and the top surface of the lower box. Some devices have a structure in which a steel support plate is inserted and a hanging rod of a suspension device is engaged with this support plate.

This example has the disadvantage that it requires an extra part, the iron support plate, and that even if the dewatering tank is omitted, the cost will not be reduced much.

As a second conventional example, there is one in which the support portion of the suspension rod of the suspension device is integrally molded near the top surface of the plastic lower box, without providing such a support plate made of iron plate.

However, in the case of plastic acid, it is impossible or extremely difficult to integrally mold a receiver that projects directly inward near the top surface of the outer box due to the structure of the mold.

Therefore, instead of protruding directly inward from near the top surface, a rising part is integrally formed from the lower bottom part at the inner corner of the lower box, separate from the outer plate, and the receiver is placed at the upper end of this rising part. The part is extended inward and molded integrally.

Providing a raised part from the bottom of the lower box in order to create a receiving part not only complicates the structure, but also complicates the mold, making the molding process troublesome, and requires the use of raw materials. The drawback is that it requires extra use and therefore increases the overall cost.

In addition, as a third example, there is one in which the support part of the hanging rod is formed directly on the bottom plate of the upper box or a plate corresponding to the bottom plate, and after the hanging rod is engaged, a waterproof lid is covered. .

This example solves the drawbacks of the above two examples, but
The drawback was that the waterproof lid was put on and taken off several times, and as a result of aging over many years, cracks formed, making the most important waterproofing insufficient.

The purpose of this invention is to improve the above drawbacks.
A bottom plate is formed integrally with the upper box, and a support part is integrally formed on the lower surface of this bottom plate by punching outward, and a hanging rod for elastically suspending the rotating device is attached to the side of the support part. It is designed so that it engages from both sides.

Embodiments of the present invention will be described below with reference to the drawings.

1 is an upper box, and 2 is a lower box, and these upper box 1 and lower box 2 do not overlap and constitute an outer box of a washing machine that also serves as a dehydrator.

This upper box 1 is made of i-plastic molded material, and a bottom plate 3 is integrally provided at the bottom to receive drainage water.
A mounting hole 5 for a sealing diaphragm 4 is bored in the center of the bottom plate 3, and an engagement groove for engaging the upper edge of the lower box 2 and a hanging rod holder (described later) are provided on the bottom surface of the bottom plate 3. The portion 6 is integrally molded.

A washing tub 7 for dehydration and dehydration is housed in the upper box 1 with gaps around the entire circumference.

The lower box 2 is also made of plastic,
Inside this lower box 2, a rotating device 10 consisting of a motor 8, a clutch 9, etc. is attached with a support plate 11, a double rotating shaft 12 penetrates the diaphragm 4 in a liquid-tight manner, and the inner shaft is used for washing. The outer shaft is directly connected to the agitating blade which rotates at the time of dehydration, and the outer shaft is directly connected to the washing tub 7, which also serves as a dehydrator and rotates at the time of dewatering.

This rotating device 10 is supported by a suspension device 13 that suspends it elastically.

That is, the hemispherical receiver provided at the upper end of the hanging rod 14 is connected to the seat 1.
The support 5 is rotatably engaged with the part 6, and the lower part of the suspension rod 14 passes through the support plate 11 and is suspended by the elasticity of the coil spring 16.

As shown in FIG.
It is molded integrally with the upper box 1 at the four corners of the lower surface of the
As shown in FIGS. 3 and 4, it has an opening 17 on the outside,
The inner bottom part 18 has a hemispherical shape with approximately the same diameter as the seat 15, and has an insertion hole 19 for the hanging rod 14 formed therein.

In order to obtain strength, side walls 20 are formed integrally with the bottom plate 3 at both sides as shown in FIGS. 4 and 5 in order to obtain strength. A reinforcing rib 22 is integrally molded between the holes 21 and 21, and a rib 23 which also serves to reinforce the insertion hole 19 and prevent the hanging rod 14 from being pulled out is integrally molded.

In addition, when there is sufficient strength even without this rib 23,
As shown in FIG. 6, the insertion hole 19 may have a continuous notch shape from the end surface, and in this way, the hanging rod 14 can be easily inserted during assembly.

For example, in order to integrally mold the portion 6 with the upper box 1,
As shown in the figure, in addition to the male mold 24 and the female mold 25, a slide mold 26 that can be extracted outwardly is used.

That is, the slide mold 26 is inserted from the outside between the bottom part 21 of the receiver part 6 and the bottom plate 3 of the upper box 1, which cannot be formed by simply opening up and down.

After the molten plastic material is press-fitted and hardened, the slide mold 26 is first removed, and then the male mold 24 and female mold 25 are opened to take out the molded product.

In addition, the receiving part 6 needs to be located below the outer peripheral lower edge 27 of the upper box 1 so that the slide mold 26 can be pulled out outward.

In the above embodiment, the receivers 6 are provided at the four corners of the lower surface of the bottom plate 3 of the upper box 1, but the receivers 6 are not limited to this, and may be provided at at least three locations.

In addition, the shape of the receiving part 6 is approximately semi-elliptical in plan view as shown in FIG. This is because it has to be extracted outward.

Therefore, as long as this condition is satisfied, the shape is not limited to a semi-ellipse.

Further, the slide die 26 does not necessarily have to be pulled out horizontally and in a direction perpendicular to the side wall, but may be pulled out diagonally upward or in the direction of the central axis.

Naturally, if this is done, the shape of the portion 6 of the receiver will also be different.

In short, it is sufficient if the bottom plate 3 of the upper box 1 can be integrally formed on the bottom surface without making holes or the like.

As mentioned above, the present invention divides the outer box into an upper box and a lower box,
In this washing machine for dehydration and dehydration, in which the upper box is also used as a dehydration receiving tank, a receiving portion of a hanging rod of a suspension device for elastically suspending a rotating device is integrally formed on the lower surface of a bottom plate that is formed integrally with the upper box; This receiver has a structure that opens from the side of the upper box and is suitable for integral molding, making it easy to assemble and structure, and requires less material such as plastic, resulting in lower costs. .

Moreover, the receiving part 6 according to the present invention can be manufactured without difficulty by using the slide mold 26 even in terms of plastic molding technology.

Further, since the receiving part 6 of the present invention is provided without making any holes in the bottom plate 3 of the upper box 1, a complete waterproof effect can be obtained without requiring a waterproof lid or the like.
