Reference numeral 42 denotes a lever control body formed at the rear of the storage container 18, which is constructed by inserting a cylindrical body 46 into a protruding rod 44 protruding from one side of the protruding piece 43 via a compression coil spring 45. When the switching lever 19 is further rotated to the right from the position where the convex part 25 engages with the recessed part 27, the compression coil spring 45 is compressed through the cylindrical body 46, and the switching lever 1 is compressed by the compression coil spring 45.
A biasing force that attempts to rotate 9 to the left is stored.

Next, the operation of this embodiment configured as described above will be described. First, move the switching lever 19 to the convex portion 25.
When the water inlet 14a is rotated to a position where it engages with the recess 26, the water inlet 14a faces the water supply channel 30 for the washing tank, and when the faucet (not shown) is opened in this state, water is supplied to the washing tank (not shown). . After water is supplied to the washing tank, detergent washing is performed in the washing tank as is well known. Next, transfer the laundry that has been washed with detergent to the dehydration basket 3, and turn the switching lever 19 so that the convex part 25 is in the concave part 27.
When the faucet is opened by rotating the faucet to the position where it engages, the water inlet 14a faces the dehydration tank water supply channel 31, and water is injected into the water sprinkling tube 4 through the dehydration tank water supply channel 31. In this state, the laundry in the dehydration basket 3 is dehydrated and rinsed. If, for example, the laundry is to be softened after completion of such dehydration and rinsing, a predetermined amount of softener is first poured into the storage container 18 from the finishing agent input port 11. Next, the switching lever 19 is rotated further to the right from the position at the time of dehydration and rinsing, against the elastic force of the compression coil spring 45, so that the engaging recess 41 of the switching lever 19 engages with the protrusion 40 of the lever 36. into the engaged state (see Figure 4). After such an operation, the faucet (not shown) of the water supply device 13 is opened to start water supply, and at the same time, the dehydration timer 8 is operated to cause the dehydration motor (not shown) to operate intermittently. Then, the water supplied from the faucet (not shown) is transferred to the water supply hose 12, the water supply port body 10, and the switching pipe 1.
The water enters the storage container 18 from the water inlet 14a through the water inlet 4, and the softener in the storage container 18 is diluted and stirred, and the liquid level in the storage container 18 gradually rises until the finishing agent input pipe 33 middle part 33a of
The liquid level reaches a higher level, and the softener aqueous solution in the storage container 18 flows from one end 33b of the finishing agent input pipe 33 to the other end 3.
It begins to flow out to 6c due to the siphon phenomenon. On the other hand, when the liquid level of the softener aqueous solution in the storage container 18 rises as described above, when the liquid level exceeds the position of the intermediate portion 33a of the finishing agent input pipe 33, the buoyancy force generated on the float 37 is applied to the lever 36. Convex portion 40 of
becomes larger than the engagement force between the switching lever 19 and the engagement recess 41, and the float 37 suddenly moves upward.
As a result, the lever 36 rotates about the pin 38 and disengages the engagement recess 41 from the protrusion 40, so that the switching lever 19 is moved by the force stored in the compression coil spring 45. Pushed by the cylindrical body 46 by the generated force, the convex portion 25 is rotated back to the left until it engages with the concave portion 27 . That is, at the same time when the softener is started to be introduced from the storage container 18 through the siphon effect of the finishing agent input pipe 33, the water supplied from the water supply device 13 flows from the water inlet 14a through the opening 16 to the water supply channel 31 for the dehydration tank. from the other end 33c of the finishing agent input pipe 33 to the water supply channel 3 for the dewatering tank.
The aqueous softener solution supplied into the dehydration tank 1 is mixed with water supplied from the water supply device 13 into the water supply channel 31 for the dehydration tank, diluted to a more uniform state, and then dispersed through a water supply device (not shown). It is supplied into the water bottle 4. and,
In this way, the water uniformly containing the softener is sprayed onto the laundry from the water-permeable micropores around the outer circumference of the water spray tube 4 through the intermittent operation of the dehydration basket 3, and is contained in the laundry. The laundry is sufficiently immersed in the water containing the softener for the predetermined time set by the spin-drying timer 8, so that the laundry is sufficiently softened. By the way, the inner diameter of the finishing agent input pipe 33 is set so that the softener aqueous solution diluted in the storage container 18 flows out in a time approximately equal to the time set in the dehydration timer 8. During the treatment, water uniformly containing the softener is always supplied to the water spray barrel 4. Next, after the above-described softening process is completed, the water supply from the water supply device 13 is stopped and the dehydration timer 8 is operated to perform a predetermined dehydration.

As described above, in this embodiment, the aqueous softener solution in the storage container 18, which has been diluted to a certain concentration by water supplied from the water supply device 28, is transferred to the dehydration tank water supply channel through the finishing agent input pipe 33 by siphoning. 31, diluted with water supplied from the water supply device 28 to the water supply channel 31 for the dehydration tank, and then supplied into the dehydration basket 3 via the water spray pipe 4, so that it is flexible. The treatment can be carried out in the dehydration basket 3, and therefore:
When performing the softening process, it is no longer necessary to transfer the laundry that has been dehydrated and rinsed to the washing tank (not shown) again, and the final dehydration can be carried out in the dehydration basket 3. In short, the laundry can be softened. Processing work becomes much easier.

Further, after the softener is temporarily stored in the storage container 18 and water is supplied to the storage container 18 to a predetermined level to dilute the softener to a certain concentration, the softener aqueous solution is poured into the storage container 18 through the finishing agent input pipe 33. Therefore, even if the viscosity of the softener varies depending on the type, the concentration of the recommended aqueous softener solution is almost constant (softeners with high concentration and high viscosity The amount of softener to be put into the storage container 18 is smaller than that of a softener with a low concentration and low viscosity, so the viscosity of the softener after being diluted in the storage container 18 is approximately constant. Finishing agent input pipe 33
The outflow time is also constant, and the laundry can be uniformly softened for a predetermined period of time.

Furthermore, in this embodiment, when water is supplied to the storage container 18 to a predetermined level at which a siphon phenomenon occurs, the switching lever 19 is switched from supplying water to the storage container 18 to supplying water to the water supply channel 31 for the dehydration tank. float 3
7 is provided in the storage container 18, the switching lever 19 automatically switches to the storage container 1 without the user's intervention.
By switching the water supply from the water supply to the dewatering tank 8 to the water supply channel 31 for the dewatering tank, it is possible to make the harvesting process easier. Although this can be reliably prevented, for example, the switching operation from water supply to the storage container 18 to water supply to the water supply channel 31 for the dehydration tank may be prevented by using the finishing agent input pipe 3.
The flexible aqueous solution flowing out from 3 is transferred to the water supply channel 31 for the dehydration tank.
The switching lever 19 may be operated manually by checking the above, and in this case, the lever 36, the float 37, and the lever control body 42 may be omitted, and the finishing agent may be bleach in addition to the softener. The present invention may be applied to all finishing agents, etc., and may be modified as appropriate without departing from the spirit of the invention.

As described above, the present invention has a simple configuration in which the water from the water supply device is switched to be supplied to the storage container by a switching body, and the finishing agent aqueous solution diluted in the storage container is introduced by siphoning. The water is poured from the pipe into the water supply channel for the dehydration tank and is sufficiently diluted to be uniformly contained in the water supplied to the dehydration basket via the water supply channel for the dehydration tank, so finishing treatment is carried out inside the dehydration tank. A finishing agent for a two-tub washing machine that can be used in a washing machine, which can greatly improve the work during finishing treatment, and which can also perform a uniform finishing treatment without being affected by the viscosity of the finishing agent stored in a storage container. Can provide input device.
