 An embodiment of the present invention will be described below with reference to the drawings.

First, FIG. 2 shows an outer box 1 of the entire two-tub type washing machine, in which a washing tub 2 and a dewatering tub 3 are arranged side by side. Among them, the agitator 4 is arranged at the bottom of the washing tub 2, and the sprinkler cylinder 5 is arranged at the center of the dehydration tub 3. The sprinkling cylinder 5 is made of, for example, a sintered synthetic resin, and has innumerable minute sprinkling holes over the entire area.

A panel 6 is provided at the rear of the upper surface of the outer box 1, a water supply valve 7 is provided at the center of the panel 6, and a detergent injection port 8 is formed at the right adjacent portion. The first and second water supply channels 9 and 10 are arranged below them.

The two water supply channels 9 and 10 are integrally formed in detail as shown in FIG. 3, and the space between them is partitioned by a partition wall 11, and the second both water supply channels 10 have predetermined portions. A detergent receiving portion 12 is formed at a position directly below the detergent injection port 8 so as to project outward and has a recessed bottom portion. The first water outlet 13 and the second water outlet 14 of the water supply valve 7 are made to face the both water supply passages 9 and 10 at a position upstream of the detergent receiving portion 12 from above. There is. It should be noted that the water supply valve 7 has a configuration in which water can be selectively discharged from the first water outlet 13 and the second water outlet 14.

Therefore, as shown in FIG. 2, an inner lid 15 is provided above the dehydration tub 3 in front of the both water supply channels 9 and 10. Water is supplied to the water bottle 5. Further, an operating portion 16 is provided on the portion of the panel 6 on the washing tub 2 side, and a "blanket" course selection key 17 is present in the operating portion 16.

A control device 18 shown in FIG. 4 is arranged on the back side portion (inside the panel 6) of the operation portion 16. The control device 18 is composed of, for example, a microcomputer, receives various operation signals from an operation unit 19 including various operation keys such as the "blanket" course selection key 17 of the operation unit 16 and performs the washing operation. A water level detection signal is input from a water level sensor 20 provided to detect the water level in the tank 2. Then, based on the input and a control program stored in advance, the control device 18 causes the control circuit 18 to drive the water supply valve 7 and a motor (washing motor) 22 provided to rotate the stirring body 4. A drive circuit 23 for driving the water, a drive circuit 25 for driving a drain valve 24 provided for draining from the washing tub 2, and a motor (dehydration motor) 26 provided for rotating the dehydration tub 3. A drive control signal is applied to each of the drive circuits 27.

Therefore, the control content of the control device 18 will be described below with reference to FIG. In FIG. 1, the water supply by the first water supply channel 9 is represented by, and the water supply by the second water channel 10 is represented by, and in addition, an example of the time of each operation is specifically represented.

First, in order to wash and dehydrate a large laundry such as a blanket, the laundry is housed around the water sprinkler 5 in the dehydration tub 3 and the detergent is injected from the detergent injection port 8. The poured detergent is dropped and stored in the detergent receiving portion 12 of the second water supply channel 10. Then, the "blanket" course selection key 17 of the operation unit 16 is operated to start the operation.

Then, the control device 18 first causes the water supply valve 7 to discharge water from the first water outlet 13, and supplies water from the first water outlet 13 into the first water supply passage 9. Therefore, water flows in the first water supply passage 9, and this water is supplied to the sprinkler cylinder 5 in the dehydration tank 3 through the inner lid 15. Then, the motor (dehydration motor) 26 is driven to rotate the dehydration tub 3. Therefore, the centrifugal force disperses water from the water sprinkling cylinder 5, and the water is stored in the stored laundry (prewashing).

Next, while rotating the dewatering tank 3, the water supply valve 7 is arranged to discharge water from the second water outlet 14, and water is supplied from the second water outlet 14 into the second water supply passage 10. Therefore, in this case, the water flows through the second water supply passage 10 to dissolve the detergent stored in the detergent receiving portion 12, and is supplied into the water spray cylinder 5 through the inner lid 15 together with the detergent. Then, the water containing the detergent supplied into the sprinkling cylinder 5 is passed through the laundry to be stored by the centrifugal force due to the rotation of the dehydration tank 3 and is discharged to the outside of the dehydration tank 3 together with the dirt. wash ).

After that, the water supply valve 7 is made to again discharge water from the first water outlet 13, and water is supplied from the first water outlet 13 into the first water supply passage 9. Therefore, water flows in the first water supply passage 9, and this water is supplied into the sprinkling tube 5 through the inner lid 15. This water supply and the rotation of the dehydration tub 3 are mainly performed alternately a plurality of times (for example, 4 times), and water is sprinkled from the inside of the water sprinkling cylinder 5 with each rotation of the dehydration tub 3, so that water is stored in the stored laundry. Carry out the wash-through component (rinse).

Finally, the dehydration tub 3 is rotated independently to shake off the water from the stored laundry (dehydration).

As described above, with this configuration, a large laundry such as a blanket can be washed and dehydrated from the beginning in the dehydration tub 3, which is different from the conventional washing tub and dehydration in the dehydration tub. There is no difficulty in transferring very heavy laundry including water after washing, and it is difficult to store the very heavy laundry in the dehydration tub 3 in a good condition. It has no sex and can be easily washed and dehydrated.

Also, unlike the conventional method of washing by stirring in water in a washing tub, centrifugal washing causes water to be sprinkled from the sprinkling pipe 5 in the central portion of the dehydration tub 3 and the laundry to be washed. It is carried out by pressing and then dehydration, which is efficient and therefore requires less water and detergent, and can be economically washed and dehydrated.

The “prewash” in the “blanket” course is set to perform washing more effectively, but is not always necessary. Also, the specific time, number of times, and other points in the course may be changed as appropriate.
