Description

[Detailed Description of the Invention] The present invention relates to a washing machine in which water can be selectively injected from water inlets provided at different positions in the upper and lower parts of the washing tub.

Conventionally, this type of washing machine has a control box with a water supply box divided into multiple chambers each having a water inlet at a different location, such as at the top or bottom of the washing tub, and a water supply hose is bent into each of these chambers. Depending on the orientation, the water inlet can be switched to either inject water from the top of the washing tub or from the bottom.

In such a system, water from the water injection hose bounces off the wall of the water supply box, scattering into the control box, and damaging the insulation of electrical components inside the box.

The present invention has been made in view of this point, and is intended to prevent water from splashing into the control box.

This will be explained below based on the drawings.

Reference numeral 1 denotes a washing tub machine frame that houses a washing tub 2 and an outer dehydration tub 3. Inside the washing tub 2 is a rotary blade 5 that is rotated by a washing motor 4.
However, inside the outer dehydration tank 3, a dehydration tank 7 rotated by a dehydration motor 6 is provided.

Reference numeral 8 denotes a control box, which is composed of a control base 9 and a panel 10, and has electrical components such as a washing timer 11 and a dehydration timer 12 built therein.

The control base 9 is divided into two left and right chambers 14 and 15 by a partition wall 13, and is integrally provided with a water supply box 16 shaped like a rectangular container with an open top.

The right chamber 15 is provided with an opening 17 at the lower part of its front surface.
This opening 17 serves as a water inlet at the top of the washing tub.

On the other hand, the left chamber 14 has an open bottom and is inserted into the upper end of a water passage 18 provided on the side wall of the washing tub.

A water inlet 19 at the lower part of the washing tub is opened in the lower part of this water passage 18, and the water that has entered the left chamber 14 is supplied into the washing tub from this water inlet 19.

On the water supply box 16, the upper end is the control base 9.
A flexible water injection hose 21 connected to a hose receiver 20 attached to the rear wall is located.

An external water injection hose 22 connected to a water faucet is connected to the upper end of the receiver tube 20 .

A water injection pipe 24 that integrally includes a shielding plate 23 is connected to the lower end of the water injection hose 21 .

This shielding plate 23 prevents the water coming out of the water injection hose 21 from hitting the wall of the water supply box and splashing into the control box 8. As is clear from FIG. It has a shape that runs along the inner surface in close opposition to it.

Further, on the side of the shielding plate 23 that is hit by the splashed water, a water collection wall 25 extending in a V-shape as shown in FIG. 5 is integrally suspended from the central water injection pipe 24.

Reference numeral 26 denotes a water injection switching heir attached to the control panel 10, which includes a pair of holding levers 2 that sandwich the water injection pipe 24.
7, and by rotating the handle 26, the water injection hose 21 connected to the water injection pipe 24 held by the holding lever 27 is bent, and its tip can be directed toward the chamber 15 or toward the chamber 14. This switch is used to switch between injecting water from the water inlet 17 at the top of the washing tub or from the water inlet 19 at the bottom.

If the water injection hose 21 is not bent, the tip of the water injection hose is above the chamber 15, as shown in FIG. 3, and water is poured from the water injection port 17 at the top of the washing tub.

At this time, the water that has hit the wall of the water supply box and bounced back hits the shielding plate 23 and is directed downward again as shown by the arrow in the figure, so that the water does not scatter into the control box 8.

When the water injection hose 21 is bent to the left as shown by the dotted line in Fig. 3 and Fig. 6, the tip of the water injection hose is directed toward the chamber 14, so that water is injected through the water passage 18 from the water injection port 19 at the bottom of the washing tub. .

At this time, water that hits the left side wall of the water supply box 16 and bounces off is blocked by the shielding plate 23 and does not scatter into the control box, and exits from the water injection pipe 24 as shown by the arrow in FIG. 6 due to the water collection wall 25. Since it is merged with water, it does not splash into the chamber 15 on the right side of the water supply box.

Therefore, water does not come out from the water inlet 17.1.
9 can be switched reliably.

Furthermore, when the water injection hose 21 is bent, the front shielding plate 23 acts as a guide because it follows both the front and rear walls of the water supply box, and the movement of the water injection hose can be stabilized. Therefore, a shielding plate with good performance can be designed. It's easy to do.

FIG. 7 shows another embodiment of the water injection pipe 24, which has an oval shape that is narrow in the direction of movement of the water injection hose.

In this way, the water injection port can be switched with a small bending angle of the water injection hose, and the durability of the water injection hose can be improved.

As described above, according to the present invention, since the shielding plate 23 is attached to the tip of the water injection hose 21, the shielding plate also moves following the water injection hose, and the water that hits the wall of the water supply box and rebounds is scattered into the control box. The insulation of electrical parts will not be impaired.

Since the shielding plate acts as a guide when bending the water injection hose, it stabilizes the movement of the water injection hose.
This provides various excellent effects such as facilitating the design of the shielding plate.
