Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a panel device for a two-tub washing machine used in general households.

Conventional structure and problems thereof Conventionally, a two-tub washing machine has a structure shown in FIGS. 1 to 3. That is, a receiver tube 2 for washing and dehydration is fixed inside the outer tub 1. . Reference numeral 3 denotes a display board made of synthetic resin on which electrical equipment such as a timer is mounted, and a plurality of L-shaped protrusions 4 and bosses 5 for fixing the display board are integrally formed at the lower part and the upper part, respectively. Further, near the center of the display board 3, there is provided a device 6 for branching and switching the water supply to the washing tank side and the water supply to the dehydration tank side. Reference numeral 7 denotes a panel stand made of synthetic resin provided below the display board 3, with an inner wall 8 and an outer wall 9 provided at a distance in front, and an outer wall 9.
A locking piece 10 that engages with the L-shaped protrusion 4 of the display board 3 is provided on the upper part of the display board 3. Also, near the center of this panel stand 7, there is a water supply passage 11 to the washing tub.
There is. Further, at the rear of the panel stand 7, a plurality of recesses 12 are provided integrally with a rear wall 13 so as to correspond to the boss portions 5. Reference numeral 14 denotes a water supply passage to the dehydration tank, and if it is provided integrally with the panel stand 7, it will cross the inner wall 8 and outer wall 9 of the panel stand 7, making it difficult to attach the display board 3, so it should be installed separately. There is.

When attaching the parts configured as above to the receiving tube 2, first attach the water supply passage 14 to the dehydration tank to the panel stand 7, then place it on the receiving tube 2 and secure it with screws etc. . Then, the L-shaped protrusion 4 of the display board 3 is engaged with the locking piece 10 of the panel stand 7, and then the boss part 5
is brought into contact with the recess 12 provided in the rear wall of the panel stand 7, and is tightened and fixed with screws or the like to complete the assembly. Here, electrical equipment such as a timer is housed in a closed space with a substantially triangular cross section that is composed of a display board and a panel stand.
Due to its configuration, it is inevitably a large part, so dimensional changes due to heat shrinkage after molding are large and dimensional accuracy is poor. In particular, the rear wall 13 of the panel pedestal 7 requires a certain level of height, but since the panel pedestal 7 has an upward opening due to its overall structure, it may warp or fall due to heat shrinkage after molding. It is difficult to assemble because the tightening holes for screws and the like do not match, and furthermore, the engagement portion between the display board 3 and the panel stand 7 comes off due to falling or impact during product transportation. Furthermore, the panel stand 7 has disadvantages such as necessarily having a complicated structure because it requires an engaging portion with the display board 3.

Purpose of the Invention It is an object of the present invention to eliminate the above-mentioned conventional drawbacks and to provide a panel device for a washing machine with a simple configuration.

Structure of the Invention In order to achieve the above object, the panel device of the washing machine of the present invention has a cross section of approximately U with the upper surface open on the receiver.
A letter-shaped nozzle part is mounted, this nozzle part is covered with a substantially box-shaped display board with an open bottom, and the lower part of this display board is fixed to the upper part of the receiver, and the lower end is formed with a rib that comes into contact with the nozzle portion.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the accompanying drawings with reference to FIGS. 4 and 5. In addition,
Components that are the same as those in the conventional example are given the same numbers and their explanations will be omitted.

In FIGS. 4 and 5, a receiver tube 2 for washing and dewatering is fixed inside the outer tub 1. Receiver 2
is provided with a plurality of mounting holes 15 for fixing with the nozzle part, which will be described later, and furthermore, on the outer peripheral wall of the receiver cylinder 2,
A plurality of attachment portions 16 for attaching to a display board, which will be described later, are provided. 17 is the nozzle part. When considering usability, it is inconvenient if the hose connected to the water faucet is in the front of the product, so it is better to place it at the back of the product. It is arranged at the bottom, and has a substantially U-shaped cross section, and is provided with a water passage section 18 to the washing tub side and a water passage section 19 to the dehydration tank side, and furthermore, the above-mentioned on the outer periphery. A flat part 20 having a through hole for fixing to the receiving tube 2, and a flat part 2 that comes into contact with a side wall rib of a display board to be described later.
1 is provided integrally. Reference numeral 22 denotes a display plate, which has a substantially box-like shape with an open bottom, and has ribs 23 at a plurality of places on the inner side of the side wall that come into contact with the above-mentioned flat part 21, and the side wall has the above-mentioned receiving tube 2 It has a plurality of through holes 24 for fixing with.

When assembling with the above configuration, first place the nozzle part 17 at a predetermined position on the receiving tube 2, and then
and fix with screws etc. Next, the display plate 22 may be further placed and fixed to the receiving tube 2 with screws or the like.
Here, electrical components such as a timer are housed in a closed space formed by the display board 22 and the nozzle section 17.

Effects of the invention As described above, in the present invention, the display board does not have an engaging part for electrical components such as a timer, and there is also no engaging part between the panel stand and the display board as described in the conventional example, so the display board is In addition, the display board can be made into a simple structure, and the display board is shaped like a box with an opening at the bottom, and the ribs provided at multiple locations on the inside of the side wall of the display board serve as reinforcement for the display board itself. The overall strength can be made stronger than that of the conventional example, and therefore, warpage, collapse, etc. due to heat shrinkage after molding are less likely to occur, and therefore, it is easier to fix to the receiving cylinder. but,
Since the display board alone has an opening at the bottom of the laundry receiver, the strength of the product is insufficient even after it is fixed to the receiver, but the nozzle part is placed below the display board, and this On the other hand, the nozzle part has a substantially U-shaped surface with an upward opening, and the display plate and the nozzle part constitute a closed space, thereby increasing the overall strength. Furthermore, with this configuration, even if the nozzle part is pushed up from below, it becomes a stopper because the ribs mentioned above are in contact with the flat part of the outer periphery of the nozzle part, and conversely, even if the nozzle part is pushed down downward, the outer periphery of the nozzle part becomes a stopper. A part of the nozzle is fixed to the receiving cylinder, and the entire nozzle part has a roughly U-shaped cross section, making it strong. It can withstand it well.
Therefore, without providing the nozzle part with a complicated engagement part with a display board as described in the conventional example, it is possible to sufficiently cope with drops, impacts, etc. during product transportation.
Further, the panel stand having the nozzle portion may be small enough to have a water supply passage portion to the washing tub and a water supply passage portion to the dehydration tub as the nozzle portion. Furthermore, as described above, serviceability is improved, as assembly and disassembly of the display plate and nozzle section can be easily performed.
