Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a washing machine with an improved operation box.

[Technical background of the invention and its problems]

2. Description of the Related Art Conventionally, a washing machine has a structure in which an operation box, which includes electrical components such as a timer for controlling operation, protrudes upwardly from the upper rear edge of a washing machine body having a washing tub. However, this product has the disadvantage that the operation box protrudes high from the main body of the washing machine, which increases the overall packaging volume, which increases both the packaging material cost and transportation cost, which increases the product cost. Therefore, in recent years, there has been a desire to keep the height of the operation box low, but simply lowering the operation box reduces the internal space, so the bottom of the operation box is sunk into the washing machine body. It is conceivable to lower the overall height of the control box, but in this case, the insertion hole formed at the bottom of the operation box and the drain hole formed at the bottom of the operation box will also be lowered. Therefore, if the water level in the washing tank becomes abnormally high due to the drainage hose being clogged, water will enter the operation box through the insertion port and drain hole, and the electrical components inside the operation box will get wet. I was afraid.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and its purpose is to reduce the height of the operation box protruding from the main body of the washing machine, thereby reducing the overall packaging volume, and to reduce the size of the washing tank. To provide a washing machine in which there is no risk of water intruding into an operation box even when the washing machine is in an abnormal overflow state.

[Summary of the idea]

In the present invention, an operation box is provided in a washing machine body having a washing tub so that its bottom part is lower than the upper end of the washing machine main body, and an insertion opening for inserting a lead wire etc. is provided in the bottom of the operation box. A check valve is installed in the drainage hole formed at the bottom of the operation box, which lowers the overall height and at the same time prevents water from entering the operation box. It is unique in that measures have been taken to prevent infiltration.

[Example of idea]

An embodiment in which the present invention is applied to a two-tub washing machine will be described below with reference to the drawings. First, in FIG. 1, 1 is the main body of the washing machine, 2 is its outer box, and 3 is a tub body having a washing tub 4 as a washing tub and a dewatering tub (not shown). It is set up. Although not shown, the washing machine main body 1 is equipped with a washing drive motor, a pulsator, a dehydration basket, a dehydration drive motor, etc., as is well known. 5
is a removable lid that covers the upper opening of the washing tub 4. Now, reference numeral 6 denotes an operation box composed of a base part 7 and a panel part 8 that closes this top opening. The operation box 6 is provided in the washing machine main body 1, so that approximately the upper half of the operation box 6 protrudes upward from the washing machine main body 1. Electrical components such as a timer 9 for operation control are provided on the back side of the panel section 8, that is, inside the operation box 6, especially on the side of the washing tub 4.
This is the picking. On the other hand, on the bottom part 7a of the base part 7,
Lead wire 11 of timer 9 (double-dashed line in Figure 1)
The insertion opening 12 through which the washing machine is inserted is formed so as to be located higher than the abnormal overflow water level of the washing tub 4, for example, higher than the upper end 1a of the washing machine main body 1. Furthermore, a drain hole 13 facing into the washing tub 4 is provided at the lowest part of the bottom 7a.
is formed. Further, a check valve 14 is provided on the side of the washing tub 4 of the drain hole 13, and this check valve 14
is a drain hole 13 for draining water such as dew condensation generated inside the operation box 6.
Water is allowed to flow out from the operation box 6, and water is prevented from flowing into the operation box 6.

According to this embodiment, the bottom part 7 of the operation box 6
a is located at a lower position than the upper end 1a of the washing machine main body 1 so that the entire operation box 6 is lowered, so that the operation box protrudes high from the washing machine main body as shown by the two-dot chain line in Fig. 2. Unlike the conventional method, as shown by the solid line in FIG. 2, the height of the operation box 6 protruding from the washing machine main body 1 can be kept low, the overall height can be reduced, and the packaging volume can be reduced. Both packaging material costs and transportation costs can be reduced. By the way, the bottom 7a of the operation box 6
By making it lower than the upper end 1a of the washing machine main body 1,
Although there is a concern that washing water may enter the operation box 6 through the insertion port 12 and the drain hole 13 if the washing tub 4 becomes abnormally overflowing due to a clogged drain hose, etc.
However, according to this embodiment, the insertion port 12 is connected to the washing tub 4.
Since the water drain hole 13 is located higher than the abnormal overflow water level, and the check valve 14 is provided in the drain hole 13, there is no risk of water entering the operation box 6.
Therefore, electrical components such as the timer 9 inside the operation box 6 will not get wet, and furthermore, the condensed water that has formed inside the operation box 6 can flow out from the drain hole 13 into the washing tub 4, making it easy to operate. Water does not accumulate inside the box 6.

Further, according to this embodiment, since the electrical component storage part of the operation box 6 is provided in the part of the washing machine main body 1 on the side of the washing tub 4, the upper part of the operation box 6 is made to protrude forward. The required space can be secured. That is, if it were to be installed at the side of the dehydration tank, there would be a dehydration lid that is opened and closed by a hinge, as is well known, and there is a risk that this would hinder the opening of the dehydration lid. There is no such fear at all, and it looks good.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but may be implemented with appropriate modifications within the scope of the gist.

[Effect of idea]

As explained above, in the present invention, an operating box is provided in a washing machine body having a washing tub so that its bottom is lower than the upper end of the washing machine main body, and a lead wire, etc. is inserted through the bottom of the operating box. A washing machine characterized in that an insertion port is provided protrudingly located above the abnormal overflow water level of the washing tank, and a check valve is provided in a drain hole formed at the bottom of the operation box, This makes it possible to keep the protruding height of the operation box from the washing machine body low, thereby reducing the overall packaging volume and greatly contributing to lower product costs.Moreover, the washing tank can be prevented from abnormally overflowing. Even under such circumstances, it is possible to reliably prevent water from entering the operation box, and it has the excellent effect that there is no risk of electrical components inside the operation box getting wet with water. be.
