Is set much larger than On the other hand, a through hole 22 shown on the right side in the figure is for allowing the signal cables 14 and 15 to pass therethrough.
This is also set to be sufficiently larger than the connectors 14a and 15a provided at the ends of the signal cables 14 and 15 so that the connectors 14a and 15a can be passed through with a margin.

A closing plate 23 shown in FIG. 2 is provided on the bottom wall plate 1a of the main body 1 of the washing machine. The closing plate 23 has a rectangular shape large enough to cover and cover the two through holes 21 and 22 formed in the bottom wall plate 1a, and can be moved by sliding on the bottom wall plate 1a. Can be. Then, on one side edge side of the closing plate 23, two aperture openings 24,
25 are provided side by side at the same interval as between the two through holes 21 and 22 described above. Each of these aperture openings 24, 25
Are formed in an elongated slit shape so as to extend in parallel from one side edge of the closing plate 23, and their width dimension is slightly wider than the outer diameter of the tubes 9, 10 or the signal cables 14, 15, and the innermost The part is cut out in a semicircle and rounded.

In addition, two ends of the closing plate 23 which are opposed to each other with the aperture openings 24 and 25 interposed therebetween are provided with two opposed members.
The two long holes 26 are formed, and the two long holes 26 are straight portions 2 extending straight along the left and right side edges.
6a, and a bent portion 26b which is connected to both ends of the linear portion 26a and which bends obliquely inside the closing plate 23 and extends.
A fixing screw 27 is passed through both long holes 26, and this is
The closing plate 23 can be fixed to the bottom wall plate 1a by being screwed into a screw hole 28 (see FIG. 1) formed in the bottom plate 1a. It is configured. Here, the distance A between the straight portions 26a of the two long holes 26 is set to be equal to the distance C between the screw holes 28 of the fixing screw 27, and the left and right long holes 26 are obliquely opposed to each other. The distances B1 and B2 between the two bent portions 26b are also set to be equal to the distance C between the screw holes 28 of the fixing screw 27, and the closing plate 23 is turned from the state shown in FIG. 3 to the state shown in FIG. It can be moved and fixed with the fixing screw 27.

Next, a procedure for leading the tubes 9, 10 and the signal cables 14, 15 out of the machine in the dishwasher of this embodiment will be described. First, the filters 9a and 10a of the tubes 9 and 10 are inserted into one of the through holes 21 to make the two tubes 9 and 10 penetrate. Also, the other through-hole 22 has a signal cable 14,
The fifteen connectors 14a, 15a are inserted, and the two signal cables 14, 15 are made to pass through. In this state, while passing the tubes 9 and 10 and the signal cables 14 and 15 through the aperture openings 24 and 25, respectively, as shown in FIG. 3, two straight holes 26a and 26a The fixing screw 27 is passed through and screwed into a screw hole 28 formed in the bottom wall plate 1a. At this time, the fixing screw 27
Is left loose and the closing plate 23 is slidable. And, the aperture openings 24, 2 and 2 of the closing plate 23
The closing plate 23 is slid in the direction in which 5 overlaps the through holes 21 and 22. As a result, the remaining openings after the tubes 9 and 10 of the through holes 21 and 22 and the signal cables 14 and 15 have been penetrated are closed by the closing plate 23, and the through holes 21 and 22 Opening area is reduced. Then, as shown in FIG. 3, all the remaining openings of the through holes 21 and 22 are closed by the closing plate 23, and
1, 22 are two tubes 9, 10, and 2, respectively.
When the size of the signal cables 14 and 15 has been reduced, the closing screws 23 are tightened to fix the closing plate 23 to the bottom wall plate.

As described above, according to the above configuration, the through hole 2
1, 22 sac tubes 9, 10 and signal cable 1
Since the remaining opening portion through which the holes 4 and 15 penetrate can be reliably closed by the closing plate 23, it is possible to prevent a mouse or the like from entering the opening portion and causing a failure in the device.

In the above embodiment, the case where the two tubes 9 and 10 and the two signal cables 14 and 15 pass through the through holes 21 and 22, respectively, has been described. Penetration morphology can be dealt with.

(1) For example, since the detergent tank 11 and the rinsing agent tank 12 are installed in the machine, the signal cable 1
When only the tubes 4 and 15 are led out of the machine and the tubes 9 and 10 are unnecessary, the following is performed. First, the aperture opening 2
After passing the signal cables 14 and 15 through 5, the closing plate 23 is rotated from the state shown in FIG. 3 as shown in FIG. A fixing screw 27 is passed through a bent portion 26b connected to a lower end portion of the long hole 26 on the right side in the drawing, and these are screwed into screw holes 2 of the bottom wall plate 1a.
8 At this time, if the fixing screw 27 is left loose, the closing plate 23 can slide along both the bent portions 26b while being inclined as shown in FIG.
The closing plate 23 is fully slid in the direction in which the opening area of the opening is reduced, and is fixed with fixing screws 27.

Thus, as shown in FIG. 4, one of the through holes 22 is covered with the closing plate 23 so that the signal cables 14 and 15 pass therethrough, while the other through hole 21 is entirely covered. It can be closed by the closing plate 23.

(2) Since the operation box 16 and the detergent tank 11 are installed in the machine, two through holes 21 are provided.
When it is desired to completely close the opening 22, as shown in FIG. 5, a fixing screw 27 is passed through the linear portions 26 a, 26 a of both the long holes 26, 26 of the closing plate 23 and screwed into the screw hole 28, and The closing plate 23 is attached to the wall plate 1a. At this time, the fixing screw 27
Is left loose so that the closing plate 23 is slidable along the straight portion 26a. Then, the closing plate 23 may be slid in the direction of closing the through holes 21 and 22 to completely close the respective through holes 21 and 22.

(3) Further, when one detergent tube 9 is passed through the through hole 21 on the left side of the drawing and two signal cables 14 and 15 are passed through the through hole 22 on the right side of the drawing, the closing plate 23 is used. The opening widths of the two long holes 26 formed in the above may be set slightly larger than the thickness of the fixing screw 27. Then, the long hole 2
Since the play is generated between the fixing screw 27 and the long hole 26 in a state where the fixing screw 27 is passed through 6, the closing plate 23 can be slightly rotated along the upper surface of the bottom wall plate 1a. Therefore,
By tilting the closing plate 23 as shown in FIG.
The apertures can be narrowed so that the through holes 21 and 22 have different opening areas.

As described above, the remaining opening portion can be reliably closed by the closing plate 23 even in various penetrating forms. Therefore, in a dishwasher of a different mode, or in other devices, the closing plate 23 of this embodiment can be used as it is, and the closing plate 23 can be shared,
As a result, the economic burden can be reduced.

In the above embodiment, the tubes 9, 10
Hole 21 and signal cable 1 through which
Although the case where the through holes 22 through which the holes 4 and 15 can penetrate are formed separately has been described, the line of the present invention is also applicable to the case where the two through holes 21 and 22 are connected to form a common through hole. A thread penetration structure can be applied. Further, the elongated hole 26 formed in the closing plate 23 is not limited to the linear shape as in the above-described embodiment, but may be partially or entirely formed in an arc shape, and the closing plate 23 can be rotated along the arc-shaped hole. You may do so.

The mechanism for adjusting the fixing position of the closing plate is not limited to forming a long hole in the closing plate, but also forming a long hole in the wall of the device and closing a fixing screw passing through the long hole. The closing plate may be fixed to the wall of the device with elastic claws without using screws, or by moving the closing plate relative to the wall without using screws. What is necessary is just to be able to adjust the substantial opening area of the through hole to a size that allows the wire to penetrate.

The tubes 9, 10 and the signal cables 14, 15 are formed by the edges of the aperture openings 24, 25.
Various modifications can be made without departing from the spirit, for example, a protective member made of resin may be provided along the contour of the aperture openings 24 and 25 so as not to damage the aperture.
