Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a two-tub washing machine that has a washing tub and a dehydrating tub, and stops the rotation of the dehydrating tub when the top lid of the dehydrating tank is opened. Concerning strained things.

Conventionally, in order to rinse in a washing tank in a short time and with a small amount of water, the washed clothes are transferred to a spin-drying tank and dehydrated while supplying water (so-called spin-drying, in which detergent is removed in advance in this spin-drying tank). It is known to perform rinsing.

However, even when water is supplied to the rotating spin-drying tank, the centrifugal force causes the water to be blown away before the water has sufficiently penetrated the clothes, resulting in the water being ineffective and wasted. It was something that would become.

The present invention has been made in view of the above points, and it is possible to supply water to the dehydration tank only when the dehydration tank is stopped. (One bottle of strained water should be used effectively.)

This will be explained below based on the drawings.

Reference numeral 1 denotes a machine frame of a two-tub type washing machine, in which a sink 4 in which an inner washing tank 2 and an outer dehydrating tank 3 are integrally arranged side by side is installed.

A rotary blade 5 is located at the bottom of the washing tub 2, and a dehydration tank 6 is located inside the outer dehydration tank 3 and is rotated by a dehydration motor (not shown).
are provided for each.

A top plate 8 having a clothes input lower is attached to the upper opening of the outer dehydration tank 3.

Reference numeral 9 denotes a dehydration upper lid that closes the clothing input lower, and hinge parts 10 and 1
The shafts 11, 11 each having one protruding tip can be opened and closed using a middle claw.

Reference numerals 12 and 12 denote bearing stands that hold the shaft 11°11.

Reference numeral 13 denotes a control box placed on the rear upper part of the crank 4, which is composed of a control base 14 and a control panel 15, and the bearing base 12 is mounted on the base 14.
is installed protrudingly.

When the upper lid 9 is opened, a safety switch (not shown) is opened to cut off the power to the dehydration motor, and a brake device (not shown) applies a brake to the dehydration motor to stop the rotation of the dehydration tank 6. It is something.

The control base 141 is integrally formed with one water supply receiver 17 partitioned into right and left by a partition wall 16.

The left side 18 (right side in Figure 1) of this water supply receiver 17 when viewed from the washing machine iE side is box-shaped, and the lower left front side 18 is provided with a water supply port 19; The right side 20 of the body 17 has a box-like shape with an open front, and a water supply gutter body 21 extending to the top of the water tank 6 is connected to the right side 20 of the body 17.

If the water supply switching valve 22 supplies water from the water supply hose 23 to the left side 18 of the water supply receiver 17, water can be supplied from the water supply port 19 to the washing tub 2, and conversely, water can be supplied to the right side 20 of the water supply receiver. Then, water can be supplied to the dewatering tank 6 via the water supply gutter body 21.

The water supply switching valve 22 has a hose receiver 2 that receives a water supply hose 23 fixed to the control base 14 with screws 24.
5, and a knob lever 26 rotatably connected to the lower end of the hose receiver 25 and protruding outside the control box.
It consists of a rotating body 27 with a protruding structure, and an L-shaped water supply pipe 28 connected to the lower end of the rotating body 27.

Then, by holding the knob 29 attached to the tip of the knob lever 26 and moving the knob left and right, the lower end of the water supply pipe 28 is positioned above either the left or right water supply receiver 18 or 20. , the water supply is switched to the washing tub 2 side or the water tank 6 side.

In FIG. 4, 30 is an O-ring.

Reference numeral 31 designates an operating lever that can rotate about one turn around a support post 32 that projects from the control base 14, and is constantly biased clockwise in FIG. 1 by a spring 33.

One end of this lever 31 comes into contact with a protrusion 34 protruding from the rotating body 27, and the other end comes into contact with a protrusion 35 protruding from the hinge part 10 when the upper dehydration lid 9 is closed.

This contact causes the operating lever 31 to rotate counterclockwise against the spring 33.

Therefore, when the dewatering top cover 9 is opened, the operating lever 31
Since there is one position as shown in FIG. 1, the knob lever 28 can be moved to either the left or right, and water can therefore be supplied to both the washing tub and the spin-drying tub.

It is now assumed that the lower end of the water supply pipe 28 is positioned on the right side 20 of the water supply receiver 17 as shown in FIG. 1 to supply water to the dewatering tank 6.

When the top cover 9 is closed, the operating lever 31 rotates counterclockwise as described above, and the rotating body 27 having the protrusion 34 that contacts one end of the lever 31 rotates clockwise as shown in FIG. The lower end of the water supply pipe 28 is connected to the water supply receiver 17.
The washing tub 2 is located on the left side 18 of the washing tub 2, and the water is supplied to the washing tub 2 from the water supply port 19.

That is, water cannot be supplied to the dehydration tank 6 when the top lid 9 is closed, and water can only be supplied to the dehydration tank when the top lid 9 is opened and the rotation of the dehydration tank is stopped.

Therefore, according to the present invention, water can only be supplied to the dehydration tank when the dehydration tank is stopped, so when performing dehydration rinsing, water can sufficiently penetrate into the clothes without being blown away by centrifugal force. , dehydration and rinsing can be carried out effectively with a small amount of water.

In addition, when the dehydration top lid is closed, the water supply switching valve automatically switches to the washing tub side, so when the washing tub is used next time (there is no need to switch the water supply valve to the washing tub side).

Furthermore, in the conventional system, a large amount of water was wasted by leaving the dehydration tank continuously supplied with water with the dehydration top lid closed, but in the present invention, the dehydration top lid was closed. When closed, the water supply is automatically switched to the washing tub side and water flows out from the easily visible place (water supply port 19 to the washing tub), which prevents the user from leaving the water supply unattended. It has various immersive effects such as its function.

Additionally, in addition to being linked to the dehydration top lid, the water supply switching valve is selectively operated by a knob lever, so water can be supplied to the washing tank as needed, for example, when washing dirty hands while supplying water to the dehydration tank. , usability can be improved.

Since the operation of the knob lever toward the dehydration tank side is prevented during dehydration (when the top lid is closed), the effect of preventing the above-mentioned wasteful water supply can be maintained.
