Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a dehydrating washing machine equipped with a so-called dehydrating and washing tub, in which washing and dehydrating are performed in the same tub, and in particular, a washing machine that automatically dispenses finishing agents, bleach, etc. More specifically, this type of washing machine automatically performs processes such as washing, rinsing, draining, and spin-drying. This system automatically adds finishing agents, etc., and provides a configuration that can greatly contribute to automation.

Embodiments of the present invention will be described below with reference to the drawings. In Figures 1 and 2, 1 is the outer casing, 1a
2 is an upper tank constituting the upper part of the outer casing 1, and 2 is a dehydration/washing tank, which is rotatably arranged in a water receiving tank 3.
Reference numeral 4 denotes a time switch placed on the upper part of the upper tank 1a, which automatically performs the following steps.

That is, when laundry and detergent are put into the spin-drying/washing tub 2 and the time switch 4 is operated, the water supply valve 5 starts to supply water, and the water supply hose 6 and upper tub 1a are
Water is supplied into the dehydration/washing tub 2 through a water supply port 6a fixed to the water supply port 6a. When a certain amount of water is supplied, the motor 7 is activated, and the pulsator 10 is driven to rotate via the pulley 8 and belt 9, and the washing process begins.

When this washing process is finished, drain valve A opens,
The washing water is drained, and then the process moves to a spin-drying process in which the spin-drying/washing tub 2 is rotated. Note that this dehydration process is referred to as a first dehydration process. After this first dehydration process is completed, a certain amount of water is then supplied,
By rotating the pulsator 10 in this state, a rinsing process is performed. Thereafter, a suitable number of rinsing steps are performed, and in between these rinsing steps, a dehydration step is performed. This process is referred to as the second dehydration process. The above is an outline of the program controlled by the time switch 4.

Reference numeral 11 denotes an annular balancer attached to the upper open end of the spin-drying/washing tub 2, which reduces vibrations during the first and second spin-drying steps.

Reference numeral 12 denotes a container containing a liquid agent such as a fabric softener attached to the inner circumferential surface of the balancer 11, and its specific configuration is as shown in FIGS. 3 and 4.

In the figure, 13 and 14 are first and second injection ports for liquid such as fabric softener, 15 is an upper lid, 16 is a first stop holding chamber that holds the liquid when the dehydration rotation is stopped, and 17 is a first partition. , 18 is a first discharge port, 19 is a first rotation holding chamber that holds the liquid agent during dehydration rotation, 20 is a first outlet, 21 is a second stop holding chamber, 22 is a second partition, 23 is a second discharge port, 24 is a second holding chamber during rotation, and 25 is a second outlet.

Next, the details of the structure and operation of the automatic loading device will be explained.

When the liquid agent is injected from the first injection port 13 of the container 12, it is held in the first holding chamber 16 during stoppage. In this state, start washing as described above. After washing is completed and the detergent liquid is drained by opening the drain valve A, the motor 7 rotates the spin-drying/washing tub 2 to perform a first spin-drying process using centrifugal force. At this time, the balancer 11 fixed to the dewatering/washing tub 2 also rotates, and the container 12 installed on the balancer 11 also rotates. This rotation causes centrifugal force to act on the liquid agent held in the first stop holding chamber 16, and the liquid agent is pressed against the first partition wall 17 and stands up. Furthermore, the first
The liquid agent flows out from the first discharge port 18 provided at the upper part of the partition wall 17, and is held against the rear wall of the holding chamber 19 during the first rotation.

When the first spin-drying process is completed and the spin-drying/washing tub 2 stops rotating, the centrifugal force no longer acts on the liquid, so the liquid falls to the bottom of the holding chamber 19 during the first rotation. The bottom surface of the first rotation holding chamber 19 is inclined toward the first outlet 20 and
The stop-time holding chamber 21 and the first outlet 20 communicate with each other, and there is a step between the bottom of the second stop-time holding chamber 21 and the first rotation-time holding chamber 19. The liquid agent that has fallen to the bottom is stored in the second stop holding chamber 21.
leaks to.

When the rinsing is completed and the second dehydration process is performed, the liquid is held in the second rotating holding chamber 24 from the second discharge port 23 provided above the second partition wall 22 in the same manner as described above. When the rotation stops, it flows out from the second outlet 25. In this way, the liquid agent is added after the second dehydration process is completed.

FIG. 5 is a sectional view showing the state when the container 12 is attached to the balancer 11, and shows the second outlet 25.
The liquid agent that has flowed out is flowed out of the dewatering/washing tub 2 through a gutter 26 formed below the second outlet 25 and enters the water receiving tank 3. When water is then poured and rinsed, the fabric softener is adsorbed onto the clothing while being mixed and stirred. After that, when the clothes are dehydrated and dried, the clothes become softer.

In the above structure and operation, by attaching the container 12 to the inner peripheral edge side of the balancer 11, it is possible to easily inject a liquid agent such as a fabric softener into the container 12, and it is also detachable from the balancer 11. It is also possible to

Furthermore, if the liquid is poured into the spin-drying/washing tub 2 from the final outlet consisting of the second outlet 25, there is a risk that the liquid will directly splash onto the clothes and cause stains. The liquid coming out from the outlet 25 is guided to the outside of the dehydration/washing tub 2 through the gutter 26,
Since the water is supplied into the water receiving tank 3, there is no occurrence of stains or the like. This gutter 26 is made of an elastic material such as rubber or soft vinyl chloride resin, and is connected to the second outlet 25.
A gutter 26 is disposed so as to be in contact with the bottom of the container 12 around the area, and the liquid coming out from the second outlet 25 is
It is sealed to prevent it from falling into the dehydration/washing tub 2.

Further, a water receiving tank 3 is disposed outside the dewatering/washing tub 2, and this water receiving tank 3 is formed with a water overflow port 27 for overflowing with water of a certain amount or more.

Since there is no effect if the liquid guided to the gutter 26 is introduced into the overflow port 27, the height of the outlet at the tip of the gutter 26 is formed to be approximately equal to or lower than the height of the overflow port 27. . Figure 5h shows the height difference.

Water supply port 6a for injecting water into the dehydration/washing tub 2
By forming these inwardly from the first and second injection ports 13 and 14 of the container 12, it is possible to prevent water from entering the container 12 from the first and second injection ports 13 and 14. The dimension d indicates the distance between the inlets 13, 14 and the water supply port 6a.

Further, as shown in FIG. 1, a dehydration cover 28 is provided on the upper opening edge of the water receiving tank 3 to prevent water splashes from coming out during dehydration.

Here, the first and second injection ports 13 of the container 12,
14 is formed inward by the dimension e from the inner diameter portion of the dehydration cover 28, so that the container 12 attached to the inner peripheral edge of the balancer 11 can rotate without touching the dehydration cover 28, and the inlet 13 of the container 12, 14 can be formed to have a height substantially equal to or higher than the dehydration cover 28, so that it can be set in a shape that makes it easy to inject the liquid into the container 12.

As described above, according to the present invention, by forming the final outlet of the container so as to correspond to the inside of the washing and dehydrating tank, the container can be installed inside the balancer, so that the liquid agent does not flow into the container. Injection is easy, and since the gutter is in contact with the area around the final outlet, it is possible to reliably prevent the liquid from flowing into the spin-drying/washing tub, and the liquid can be smoothly poured out of the spin-drying/washing tub. Since the liquid flows out in the opposite direction, there is no need for the liquid to be applied directly to the clothes, and there is no need to worry about stains.
