Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a dehydration receiver support device for a washing machine that elastically supports the dehydration receiver and absorbs vibrations of the dehydration receiver during operation.

A conventional one-tub type dehydrating washing machine is constructed as shown in FIG. In Fig. 1, 1 is the main body of the washing machine, 2 is a dehydration receiver installed in the washing machine main body 1, 3 is a washing and dehydration tank rotatably installed in the dehydration receiver 2, and a pulsator is installed in the center of the bottom. 4 is placed. 5 is a motor, the rotation of which is transmitted to the pulsator 4 and the washing and dehydrating water tank 3 via a V-belt 6 and a clutch mechanism 7. Lower supports 8 are provided at four locations on the lower side of the dehydration receiving cylinder 2, and four lower supports 8 are provided at four locations on the lower side surface of the dehydration receiving cylinder 2.
A book support rod 11 is arranged, and the upper end of this support rod 11 is attached to upper support members 12 provided at the four corners of the washing machine main body 1.
are connected to each other via a spherical seat 13 and a pin 14. The above-mentioned mechanism supports the dewatering receiver 2 elastically and so as to be able to swing back and forth to the left and right.

According to the above-mentioned dehydration receiver support device, in order to assemble it, first, the support rod 11 is attached to the lower support member 8 which is protruded from the dehydration receiver 2 through the spring 9 and the spring storage portion 10.
After passing through the water, while lifting it together with the dehydration receiver 2,
As shown in FIG. 2, the upper end of the support rod 11 is passed through the through hole 15 of the upper support body 12, and in this state, the spherical seat 13 and the pin 1 for preventing the spherical seat 13 from coming off.
4 had to be assembled using a very troublesome procedure, which resulted in poor workability and mass productivity. Note that 17 is a rib for reinforcing the upper support body 12, and 18 is a receiving portion for the spherical seat 13.

In order to eliminate these shortcomings,
Japanese Patent No. 35346 proposes an improved dehydration receiver support device as shown in FIG. this is,
The washing machine main body 1 is inserted into the upper support body 12 through the through hole 15.
A notch 16 is provided that reaches the inner edge of the support rod 11, and the support rod 11 is inserted into the through hole 15 through the notch 16 with the support device assembled in advance, and the spherical seat 13 is engaged with the receiving portion 18. be. In this way, ease of assembly is improved, and the dehydration receiver 2 can be easily suspended and supported on the washing machine main body 1.

However, when the dehydration receiver 2 is suspended from the washing machine main body 1, the lower end of the support rod 11 is generally closer to the inside than the upper end, as shown in FIG. weight of water,
The repeated load during dehydration vibration acts on the spherical seat 13 as a vertical component y and a horizontal component x, and the horizontal component x acts in almost the same direction as the notch 16 of the upper support 12. There is a very strong possibility that the spherical seat 13 engaged with the support body 12 will come off during the operation of the washing machine. Furthermore, since the direction of the notch 16 and the horizontal component x are almost the same as described above, the upper support body 12 is easily destroyed from the notch 16,
Furthermore, there are also notches 16 for reinforcing ribs to prevent this.
Because of this, they cannot be provided in an effective continuous manner. Therefore, the upper support 1 has sufficient strength.
2, it is necessary to take measures such as increasing the plate thickness, which not only leads to increased costs, but also offsets improvements in workability and mass productivity. is the upper support 12
This creates an adverse condition in which there is a strong possibility that it will come off while driving.

The present invention solves the above-mentioned drawbacks of the conventional example, and provides the upper support with sufficient strength, and also simplifies the assembly of the upper support and the support rod with the spherical seat attached, thereby improving workability and mass production. The present invention provides a dehydration receiver support device for a washing machine that improves the performance. Hereinafter, embodiments will be described in detail with reference to the drawings.

5 and 6 show an embodiment of the present invention, in which an upper support member 1 provided in a washing machine main body 1 is shown.
2 may have substantially the same configuration as the conventional example shown in FIG. That is, the upper support body 12 has a substantially triangular plate shape.
A receiving part 18 of a spherical seat whose bottom surface forms an arc-shaped curved surface is recessed approximately in the center thereof, and a through hole 15 is provided in the center thereof, and a reinforcing rib 17 is provided on one side facing inward of the washing machine main body. It is provided. Support rod 20
has its upper end bent back approximately 180 degrees to form a folded part 20a, and the distance between this folded part 20a and the straight part of the support rod 20 is equal to that of the upper support 12.
From the through hole 15 of the receiving part 18 to the reinforcing rib 17
Furthermore, the length of the folded portion 20a is such that a portion of the folded portion 20a protrudes downward from the through hole 15 in the assembled state as shown in FIG. The spherical seat 21 is provided with an insertion hole 22 in the center thereof into which the folded portion 20a is inserted, and a fitting portion 23 extending from the insertion hole 22 to the edge into which the bent portion 20b of the support rod 20 is fitted. Further, a small protrusion 23a for preventing the support rod 20 from coming off upward is integrally formed on the fitting portion 23.

Next, in the support device having the above configuration, the support rod 2
0 and the upper support body 12 will be explained.
First, the folded part 20a of the support rod 20 is inserted into the insertion hole 22 of the spherical seat 21, and the bent part 20b is inserted into the fitting part 23.
After assembling the spherical seat 21 integrally with the support rod 20 in advance by fitting the spherical seat 21 into the support rod 20, the tip of the folded portion 20a of the support rod 20 protruding below the spherical seat 21 is inserted into the through hole of the receiving portion 18 in the upper support body 12. 15,
The spherical seat 21 is attached to the receiving part 1 so that the straight part of the support rod 20 is located outside the reinforcing rib 17 of the upper support body 12.
8. As a result, the dehydration receiver 2 is suspended from the washing machine main body 1.

As is clear from the above description, according to this embodiment, the dewatering receiver can be attached to the dehydration receiver by assembling the spherical seat 21 in advance and hooking the integrated support rod 20 onto the upper support 12. The washing machine body 1
Because it can be suspended from
Compared to the method in which the support rod 11 is passed through the through hole 15 of the upper support body 12 and the spherical seat 13 and pin 14 are attached while the dewatering receiver 2 is lifted, the workability is greatly improved, and it is also easier to mass-produce. It will be advantageous. Further, since the upper support 12 has no notch at its edge, it maintains sufficient strength, and at the same time, since the folded part 20a of the support rod 20 is passed through the through hole 15 of the upper support 12, dehydration is achieved. Spherical seat 2 when driving
1 will not come off from the upper support 12, which is extremely effective in terms of safety.

As explained above, according to the present invention, it is extremely easy to suspend and attach the dehydration receiver to the main body of the washing machine, and workability and mass productivity can be improved.
In addition, the structure is simple, and has great practical effects, such as being able to securely attach the support rod without slipping off, and provide sufficient strength to improve safety.
