Description

Detailed Description of the Invention The present invention is a two-tank washing machine that has a washing tank and a dehydration tank, and stops the rotation of the dehydration tank when the dehydration top cover is opened, and a water supply channel to the dehydration tank is provided to connect the dehydration tank to the dehydration tank. Regarding things that can supply water.

Conventionally, in order to perform rinsing in a washing tub 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, thereby removing the detergent in advance in this spin-drying tank. It is known to do this.

However, even when water is supplied to a rotating spin-drying tank, the water is splashed away by centrifugal force before it has fully penetrated the clothes, and the water supply is not used effectively and is wasted. Ta.

The present invention has been made in view of this point, and it is possible to supply water to the dehydration tank only when the dehydration tank is stopped, so that water can sufficiently penetrate into the clothes.
The aim is to use water 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 tank 4 including a washing tub 2, an outer dehydration tub 3, and the like are integrally arranged side by side.

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

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

9 is a dehydration upper lid that closes the clothes input lower, and hinge parts io and i
It can be freely opened and closed around a shaft IL11 protruding from the tip of o.

12.12 is a bearing stand that holds the shaft 11°11.

13 is a control box.

When the dewatering top cover 9 is opened, a safety switch (not shown) is opened to cut off the power to the dehydrating motor, and a brake device (not shown) is applied to stop the dehydrating motor, that is, the dehydrating tank 6.

At the rear of the upper part of the washing tub 2, there is a water supply receiver 15 that is partitioned into left and right parts by a partition wall 14, and the left side (right side in Figure 1) 16 when viewed from the front is box-shaped and has a front wall. The water supply port 17 facing the washing tub 2 is opened, and the right side 18
is gutter-shaped and extends above the overflow chamber 20 having the overflow port 19 of the washing tub, and is open at the tip.

Above the partition wall 14 is a water supply port body 2 that can be bent left and right.
1, and when the water supply port body 21 is bent to the left (the state shown in Figure 1A), water is supplied from the water supply port 17 to the washing tub 2, and when it is bent to the right (the state of the opening in the same figure). supplies water to the gutter 18 on the right side of the water supply receiver.

Reference numeral 22 designates a movable water supply gutter body which receives water flowing out from the tip of the valve 18 and guides the water to a fixed water supply gutter body 23 opened above the dehydration tank 6. It can be rotated freely around the center.

The support shafts 24,24 are held by a pair of bearing pieces 26 that protrude from a cover 25 covering the upper side of the overflow chamber 20.

The movable water supply gutter body 22 is constantly biased clockwise by a spring 27 (see FIG. 4) provided between the movable water supply gutter body 22 and the cover 25, and is in the state shown in FIGS. 1 and 2. Water is guided to the fixed water supply gutter body 23 and supplied to the dehydration tank 6.

However, the movable water supply gutter body 22 is provided with a flange 28 on one side wall thereof, and on the other hand, the hinge portion 10 of the dewatering top lid is provided with an engagement protrusion 29, and when the top cover 9 is closed, this engagement protrusion 29 is provided. comes into contact with the flange 28, and the movable water supply gutter body is rotated counterclockwise (as shown in FIGS. 3 and 4) against the spring 27.

As a result, water from the gutter 18 is guided to the overflow chamber 20 through the opening 30 provided in the cover 25, and is not supplied to the dehydration tank 6.

The water led to the overflow chamber 20 is prevented from flowing out through the overflow port 19, and is eventually supplied to the washing tub 2.

Next, the operation will be explained.

When the washed clothes are transferred to the dehydration tank 6 and the top cover 9 is left open, the movable water supply gutter body 22 is
It is in the state shown in the figure.

Therefore, when the water supply port body 21 is turned into a mouth state, the water supply port body 21
The water is led to the dewatering tank 6 via the gutter 18, the movable water supply gutter body 22, and the fixed water supply gutter body 23.

At this time, the dehydration tank 6 is stopped because the upper lid 9 is open, and the clothes in the dehydration tank can be sufficiently soaked with water.

Next, when the top cover 9 is closed in order to rotate the dewatering tank 6, the movable water supply gutter body 22 rotates as described above to stop supplying water to the dehydrating tank and to supply water to the washing tub 2.

(Situations in Figures 3 and 4) Therefore, when the dehydration tank rotates, water is not supplied to the dehydration tank.

This means that whenever you try to supply water to the dehydration tank, the dehydration tank will always stop, and the water will not be splattered away before it has fully penetrated the clothes, allowing it to penetrate sufficiently with a small amount of water and effectively dehydrating and rinsing. can be done.

Furthermore, by closing the top lid, the water supply is switched from the dehydration tub to the washing tub, but this water supply can be used as the next rinse water, or if rinsing is not performed, it is easy to know that water is being supplied to the washing tub. This helps prevent a large amount of water from being wasted by leaving it as is.

(In the conventional device in which water could be supplied to the dehydration tank with the top lid 9 closed, the water supply was sometimes left unattended, resulting in a large amount of water being wasted.

) FIGS. 5 and 6 show another embodiment in which there is no Roe movable water trough, and instead the trough 18 of the water receiver 15 extends above the fixed water trough 23.

When the upper lid 9 is closed by the hinge part 10 of the dehydration upper lid 9, it is closed as shown in the dashed line in FIG. This is to supply water to the washing tub 2.

If the water is made to flow out from the water supply port 1γ when the top cover is closed in this way, it will be easily seen and will have a significant effect in preventing the wasteful use of a large amount of water.

At this time, if the water is also allowed to flow out from a small hole 31 other than the water supply port 17, this effect will become even more remarkable.

Furthermore, the fixed water supply gutter body 23 can also be integrally molded with the top plate 8.

As described above, according to the present invention, when water is to be supplied to the dehydration tank, the dehydration tank is always stopped, and the clothes can be sufficiently soaked with water and can be effectively dehydrated and rinsed with a small amount of water. Even if water is being supplied to the dewatering tank, if the top cover is closed, the water supply will be switched to the washing tank side, and since it is easily visible, there is no fear of leaving the water supply unattended.This pipe has various excellent effects.

By simply placing a part of the gutter body of the water supply channel over the water supply port and rotating it in conjunction with the upper cover, the water supply can be cut off and the flow changed, making it possible to carry out effective rinsing with an extremely simple configuration. It is possible.
