Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for holding a flexible water supply hose that connects a water supply box and an electromagnetic water supply valve of a washing machine.

As seen in conventional washing machines, a washing machine has a structure in which a water inlet is provided on the operation box at the top of the washing machine main body, and an electromagnetic water supply valve is placed inside the operation box and attached to the operation panel on the front of the operation box. When assembling or servicing, use the engagement part between the operation box and the operation plate as a fulcrum to tilt the operation plate onto the laundry lid and remove the control parts attached to the operation plate. It must be long enough to allow the board to fall. However, in the case of a structure in which the electromagnetic water supply valve is attached to the top of the operation panel, if the length is set to be sufficient when the operation panel is folded down as described above, the water supply hose will be long enough when the operation panel is attached to the operation box. Otherwise, the water injection hose may bend in the middle, and the middle part of the water injection hose may become lower than the water injection mouthpiece, resulting in water remaining inside the water injection hose after water supply is completed. If water remains, the remaining water may drip and stick to the clothes when you take them out after the spin cycle is complete, or the remaining water may freeze in the winter and cause the water injection hose to burst. It's large.

The present invention solves the above-mentioned conventional problems, and one embodiment of the present invention will be described below. In the figure,
Reference numeral 1 denotes an outer frame constituting the main body of the washing machine, and a plurality of outer frame receivers provided on the upper part of the frame are provided with a hanging rod 3 via a slider 2. A buffer tube 4 with a built-in tube (not shown) is provided. Reference numeral 5 denotes an outer tank receiving part, which is suspended by a suspension rod 3 through a buffer pipe 4, thereby elastically suspending the outer tank 6. Reference numeral 7 denotes a board fixed to the bottom of the outer tank 6, and to this board 7, a rotating mechanism section 8 containing a speed reduction mechanism during washing, a switching mechanism for washing and dewatering, an electric motor 9, etc. are attached. Further, an inner tank 10 and a pulsator 11 are rotatably attached to the shaft of the rotation mechanism section 8.

Moreover, on the top of the outer frame 1, there is a top plate part 12 and an operation box 1.
A member integrally molded with 3 is fixed. or,
A washing lid 14 is pivotally supported on the top plate portion 12.
Further, above the upper end opening of the inner tank 10, a top plate portion 12 is provided.
A water inlet cap 15 fixed to is located. The water injection cap 15 has an opening formed in its lower part, and a connection port 1 for a water injection hose, which will be described later, in the other part.
5a is provided.

16 is the operation panel, which controls water supply, washing, draining, rinsing,
It is equipped with control switches such as a time switch that controls a series of cycles such as dehydration, a pressure switch for water level detection, and a changeover switch for changing water flow.
A substantially L-shaped claw is formed at the lower end of the operation plate 16, a hole is formed at a corresponding position on the operation box 13, and the claw and the hole are engaged. The operation box 1 is screwed to the mounting boss 17.
An operation plate 16 is fixed to 3. Also, operation panel 1
A decorative board 18 is fixed to the surface of 6.

Reference numeral 19 denotes a concave portion provided on the upper surface of the operation plate 16, in which a hole 20 is formed, and around this hole 20, a hanging rib 21 having a substantially half-moon arc shape is formed. A boss 22 is formed on the outside of the hanging rib 21. 23 is an electromagnetic water supply valve, and its connection base 24
into the hole 20, and insert the collar 25 into the hanging rib 2.
1 and fixed to the boss 22 with a screw 27 via the mounting portion 26.

A water injection hose 28 has one end connected to the outlet 29 of the electromagnetic water supply valve 23, and the other end communicates with the connection port 15a of the water injection cap 15 as described above.

The water injection hose 28 is connected to the operation panel 16 as shown in FIG.
It needs to be long enough for the operation board 16 to fall down when it is folded down. The reason is that the time switch 30, changeover switch 31, and
This is to tilt the operation panel 16 forward when assembling parts such as the water level changeover switch 32 or during service.

If the length of the water injection hose 28 is set to such a length that the operation panel 16 will fall down, the water injection hose 28 will be too long when the operation panel is attached to the operation box 13 as shown in FIG. The middle part of the water injection hose 28 may be bent or twisted, making it impossible for water to pass through, or the middle part of the water injection hose 28 may be located at a lower position than the connection port 15a of the water injection mouthpiece 15, resulting in residual water.

In order to prevent such problems from occurring, the bottom surface of the operation box 13 in the direction directly below the outflow port 29 of the electromagnetic water supply valve 23 is designed so that the upper end surface is located at a higher position than the water inlet cap 15. Convex stepped portion 33
are integrally formed. A substantially triangular inclined convex portion 34 is integrally formed on the upper end surface of this convex step portion 33, and the inclined surface 3 of this inclined convex portion 34 is
It has a flat portion 35 continuous to 4a.

The operation plate 16 has an L-shaped locking piece 16 at its lower part.
It is attached to the operation box 13 so as to be openable and closable using a as a fulcrum. During this attachment, the water injection hose 28 comes into contact with the inclined convex part 34, and then slides on the inclined surface 34a to be located on the flat part 35. This flat portion 35 is located at a higher position than the connection port 15a of the water injection cap 15, and prevents water from remaining in the middle of the water injection hose 28.

When attaching the operation plate 16 to the operation box 13, the water injection hose 28 is connected to the inclined surface of the inclined convex portion 34.
A movement of a dimension A between the state in which it is in contact with 4a and the state in which it is located on the flat portion 35 is performed. Therefore, the length of the water injection hose 28 may be set to a length that allows sliding movement of the dimension A described above. Note that as the water injection hose 28, it is preferable to use a highly flexible bellows hose made of resin.

As described above, according to the present invention, when the electromagnetic water supply valve is attached to the operation panel and the operation panel is opened and closed by rotating motion with respect to the operation box, bends in the water injection hose and residue in the water injection hose can be avoided. Water can be prevented, and the structure is as simple as providing a convex step with a sloped convex part and a flat part on the bottom of the operation box, which stabilizes the quality of the water injection surface. At the same time, it is possible to improve the workability of assembling the operation panel.
