Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer frame structure of a washing machine.

[0002]

2. Description of the Related Art Conventionally, the outer frame structure of a fully automatic one-tub type washing machine is conventionally formed by integrally forming an outer frame body, a front panel and a side panel with a material such as a synthetic resin, and a top cover is provided in an upper opening. , The lid and the operation panel are attached, and finally the rear panel is attached to the opening on the rear surface to form the outer box.

Electrical components such as various operation switches and boards are arranged on the operation panel. This board is 100
There are a V type and a low voltage type, but conventionally, these two types of substrates were integrated into one and arranged on the operation panel.

[0004]

When repairing or maintaining electrical equipment such as a board, the rear panel is removed and then the operation panel is removed, resulting in poor workability.
In particular, when a clothes dryer is combined above the washing machine to form a home laundry, if the support pillar supporting the clothes dryer is attached to the rear part of the outer box of the washing machine, the work must be performed after removing the support pillar. It will be a big one.

Further, when the 100V board is separated from the low voltage board to be attached to a place where maintenance can be easily performed, it is necessary to separately cover this with a metal cover or the like in order to ensure the safety. Becomes complicated.

Therefore, in the prior art, for example, Japanese Unexamined Patent Publication No. 4-19729.
As shown in Japanese Patent Publication No. 5, there is a structure in which an opening portion is provided on the front surface of the outer frame of the washing machine and the front opening portion of the outer frame is covered by a front cover. Although the workability can be improved, safety is not taken into consideration when the 100V board is attached separately from the low-voltage board.

The object of the present invention is to eliminate the disadvantages of the prior art example, improve the workability of maintenance and repair when the 100V board is mounted separately from the low-voltage board, and do not install a metal cover or the like separately. Another object of the present invention is to provide an outer frame structure of a washing machine which can ensure its safety.

[0008]

In order to achieve the above object, the present invention firstly provides an outer frame structure of a washing machine, wherein a panel is detachably attached to an opening of an outer frame body.
A mounting plate having a recess for accommodating a 100V board is integrally projectingly provided from the outer frame body toward the opening, and a panel for closing the opening and a mounting plate projecting on the outer frame body are used to mount the 100V board. It is the gist to form.

Secondly, the gist is that the opening for projecting the mounting plate of the 100V substrate is either the front surface or the side surface.

Third, the gist is that the panel for closing the opening and the outer frame body are made of metal.

[0011]

According to the first aspect of the present invention, by closing the opening of the outer frame main body on which the mounting plate is projecting with the panel, the panel acts as a lid of the recess for accommodating the 100V substrate, and is mounted here. A box is formed as a result, and the 100V board is sandwiched between a mounting plate having a storage recess and a panel, and is enclosed, so that a separate mounting box is not required.

According to the second aspect of the present invention, in addition to the above-mentioned function, the opening for projecting the mounting plate of the 100V board includes:
By using either the front side or the side, even when a clothes dryer is combined with a washing machine to form a home laundry, without removing the support pillar for the clothes dryer, remove only the panel that closes the opening as it is. It is possible to do maintenance work easily.

According to the third aspect of the present invention, the panel for closing the opening and the outer frame body are made of metal so that
The 0V substrate can be surrounded by a metal member, and safety can be ensured without separately providing a metal cover or the like.

[0014]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is an exploded perspective view showing an embodiment of an outer frame structure of a washing machine of the present invention, and FIG. 2 is a front view of a mounting plate of a 100V substrate which is a main part of the washing machine. The water receiving tank 2 is arranged in the outer box 1, and the water receiving tank 2
A washing / dehydrating tub 3 is provided inside, and a top cover 5 provided with a lid 4 is attached to the upper opening of the outer box 1. A rear electrical component panel 6 is provided at the rear of the top cover 5 and a front is provided at the front. Each of the electrical component panels 7 is attached. In this case, the rear electrical component panel 6 is provided with, for example, a water supply valve, a water level sensor, a safety switch, etc., and the front electrical component panel 7 is a low voltage substrate of the substrates.

The outer box 1 is for covering an opening 9 formed around a metal outer frame body 8 with a panel made of a metal, and at least a front panel 10 and a side panel 1.
Either one of them (the front panel 10 in the illustrated example) is detachably attached to the outer frame body 8.

On the outer frame body 8 to which the front panel 10 is detachably mounted, a mounting plate 13 having a recess 12 for accommodating a 100V substrate is provided so as to project from the outer frame body 8 toward the opening 9, and the opening is formed. A front panel 10 that closes 9 and a mounting plate 13 that projects from the outer frame body 8 form a mounting box for a 100V substrate.

In this way, 100 is stored in the storage recess 12.
When the V board is housed, the front panel 10 is attached to the outer frame body 8 and the opening 9 is closed, the front panel 10 acts as a lid of the housing recess 12 of the 100V board, and the 100V board is mounted with the housing recess 12. It is sandwiched and enclosed by the plate 13 and the front panel 10, where the mounting box is formed as a result.

Since the front panel 10 and the outer frame body 8 are made of metal, the safety of the 100V board can be ensured.

At the time of maintenance of the 100V board, etc.
This can be easily done by removing only the front panel 10.

Further, since the 100V board is arranged behind the front panel 10 of the outer box 1 and the upper part is covered with the top cover 5, the washing water does not circulate there, and the water treatment is simultaneously performed. It

[0021]

As described above, according to the outer frame structure of the washing machine of the present invention, first, by closing the opening of the outer frame main body having the mounting plate projecting with the panel, the panel is a 100V board. Acting as a lid for the storage recess, the resulting mounting box is formed therein, and the 100V board is sandwiched between the mounting plate having the storage recess and the panel, so that a separate mounting box is not required.

Secondly, the opening for projecting the mounting plate of the 100V board is formed on either the front surface or the side surface, so that even if the clothes dryer and the clothes dryer are combined into a home laundry, the clothes dryer can be used. Without removing the supporting column, you can remove only the panel that closes the opening as it is, and you can easily perform work such as maintenance.

Thirdly, by making the panel for closing the opening and the outer frame body made of metal, the 100V substrate can be surrounded by a metal member, and safety can be secured without separately providing a metal cover or the like. It is a thing.
