On the other hand, there is also a pulsator 14 at the bottom of the semi-automatic washing tub 5.
A back blade 15 for a pumping action is integrally formed on the back surface of this pulsator. Further, to this pulsator 14, rotational force is transmitted via pulleys 17, 18 and a belt 19 from a motor 16 mounted on the bottom plate of the machine frame.

Reference numeral 20 denotes a communicating pipe connecting the bottoms of both washing tubs 4 and 5, and an intermediate valve 21 is interposed within this communicating pipe. 22 is a drain pipe, which connects each washing tank 4 and 5.
Drain valves 23 and 24 are provided at the branched portions, respectively. Further, 25 and 26 are overflow pipes for the respective washing tubs.

A water supply pipe 27 branches into a non-automatic washing tub and a fully automatic washing tub, and is provided with water supply valves 28 and 29, respectively.

FIG. 2 is a block diagram showing the connection state between the microcomputer 30 installed in this washing tub and each device.The display circuit 31 connected to this microcomputer receives a 5-bit timing signal and a 6-bit timing signal. The light emitting diode is lit with the segment signal. Also, reading from the keyboard 2 is performed using 4 bits of the timing signal. 32 indicates switch group, 50/60Hz
The open/close states of the changeover switch, lid switch, safety switch, and liquid level switch are input to the microcomputer 30 in 4 bits.
33 is a group of AC control elements, which control the semi-automatic washing tub side water supply valve 28, the semi-automatic side motor 16, the fully automatic side water supply valve 29, the fully automatic side motor 9, and the semi-automatic side according to an 8-bit signal output from the microcomputer 30. A drain valve 24, a fully automatic side drain valve 23, and an intermediate valve 21 are opened and closed. 34 is an external interrupt circuit for time counting, and 35 is a buzzer.

FIG. 3 shows a keyboard, and the keys surrounded by a triple frame are the operation keys for the semi-automatic washing tub, and the keys surrounded by a single frame are the operation keys for the fully automatic washing tub. 36 is a washing timer on the semi-automatic washing tub side, and the numbers written above the light emitting diodes 37, 37, . . . forming the display section of the timer indicate the operating time in minutes. When time up key 38 is pressed,
Each light emitting diode at 0.5 second intervals starts from 1 minute to 10
The light emitting diodes light up sequentially toward the minute, and when you release the time up key 38, no more light emitting diodes light up, so you can set the time in minutes in the range of 1 to 15 minutes. Also, when the time down key 39 is pressed, the light emitting diodes 37, which are lit, go out one by one at intervals of 0.5 seconds.

When the water supply key 40 is pressed, water is supplied to the semi-automatic washing tub 5 side. Water supply stop key 41 when the predetermined water level is reached
When is pressed, the water supply is stopped, and then washing is started by pressing the standard water flow start key 42 or the soft water flow start key 43. When operating with standard water flow, the pulsator 14 rotates for 15 seconds and pauses for 5 seconds, and then reverses; when operating with soft water flow, the pulsator rotates for 3 seconds and pauses for 7 seconds, and reverses. driving,
The light emitting diodes 37 of the washing timer go out every minute, and the operation ends when all of them go out. When the stop key 44 is pressed, the motor 16 stops even during operation, the memory time in the microcomputer 30 becomes 0, and
The light emitting diodes 37 of the washing timer are turned off.
Note that even after pressing the stop key 44, the remaining time is stored in the microcomputer 30 for a certain period of time, and if the standard water flow start key 42 or the soft water flow start key 43 is pressed within this certain period of time, operation is resumed. You can.

The simultaneous water supply key 45 is a key for supplying water to both the fully automatic washing tub 4 and the semi-automatic washing tub 5 at the same time. When this key is pressed, the water supply valves 29 and 28 to both the washing tubs 4 and 5 are turned on. At the same time as opening, the intermediate valve 21 also opens.
By opening this intermediate valve, the water levels in both washing tubs 4 and 5 will always be the same, so by providing a water level switch only in the fully automatic washing tub 4, the water levels in both washing tubs 4 and 5 can be adjusted. can be controlled. The simultaneous washing key 47 is used for fully automatic washing tub 4 and semi-automatic washing tub 5.
This key is used to wash both washing tubs at the same time. When this key is pressed and the start key 46 is pressed, the intermediate valve 21 opens and both washing tubs are brought into communication, and at the same time both water supply valves 28 and 29 open. Both washing tubs 4 and 5
water at the same time. When the water level reaches a predetermined level, the water level switch on the fully automatic washing tub 4 side is set to energize the motors 9 and 16 of both washing tubs, and both pulsators 8 and 1 are turned on.
4 rotate at the same time.

Figure 4 is a process diagram for simultaneous washing. After the washing process is complete, drain valves 23 and 24 are opened for 4 minutes to drain water, and then the motor 9 on the fully automatic washing tub side is rotated clockwise to spin out the water. conduct. At this time, of course, the clutch 10 is switched so that the rotational force of the motor is transmitted to the inner tank 7.

Note that FIG. 5 is a process diagram when the fully automatic washing tub 4 is used alone, and the draining time after reusing the washing liquid, which will be described later, is 2 minutes. However, the drain time when running simultaneously is 4 minutes because the two washing tubs 4 and 4 have a drain time of 4 minutes.
This is because water is drained from 5 at the same time, so it takes a long time to drain water.

Returning to Figure 4, the semi-automatic washing tub 5
Since there is no dewatering mechanism on the side, while the fully automatic washing tub 4 side is dewatering, the semi-automatic washing tub side is inactive. After the dewatering operation on the fully automatic washing tub side is completed, water is supplied to both washing tubs at the same time again. After the rinsing process is completed, the water is drained, and when the water level switch is stopped due to the water being drained, the fully automatic washing tub 4 side performs a spin-driving operation with a further delay of one minute. FIG. 6 is a flowchart showing the process. The reason why dehydration is not started until one minute has passed after the water level switch is reset is as follows. That is, when performing dehydration operation, the rotation of the inner tank is generally started with some liquid remaining in the outer tank to prevent the inner tank (dehydration tank) from abnormally vibrating. Therefore, the water level switch is generally adjusted so that it is reset when some liquid remains in the outer tank. However, in the case of the present invention, the rinsing water in the fully automatic washing tub 4 and the semi-automatic washing tub 5 is drained at the same time, so the drainage capacity is low. Therefore, if spin-drying is started immediately after resetting the water level switch, the rinse water in the fully-automatic washing tub 4 and the semi-automatic washing tub 5 is drained at the same time. This is because the water level in the fully automatic washing tub 4 side rises together with the water that originally remained, making it impossible to spin out the water.

After continuing the operation in this manner, all operations are terminated when the fully automatic washing tub side completes the final dehydration. Reference numeral 48 is a washing liquid automatic reuse key, and when this key is pressed, after the washing operation in the fully automatic washing tub 4 is completed, the washing liquid is transferred to the non-automatic washing tub 5 side. FIG. 7 shows the operation in the form of a flowchart. When the washing operation on the fully automatic washing tub 4 side is completed, it is determined whether the motor 16 on the non-automatic washing tub 5 side is operating or not, and on the non-automatic washing tub side. Check whether the water supply valve 28 is open. This is checked by signals entering the microcomputer 30 from the motor 16 and water supply valve 28. Note that if there is a water level switch on the side of the non-automatic washing tub 5, the signal from this water level switch may be checked. When the motor 16 is stopped and the water supply valve 28 is closed, that is, when the non-automatic washing tub 5 side is not operating, time counting is started and the intermediate valve 21 is opened. When 10 seconds have passed after the start of time counting, the pulsator 14 on the non-automatic washing tub 5 side is rotated, and its pump action transfers the washing liquid from the fully automatic washing tub 4 side to the non-automatic washing tub 5 side through the communication pipe 20. . When two minutes have elapsed from the start of counting, the intermediate valve 21 is closed and the pulsator driving motor 16 is stopped to complete the transfer of the washing liquid. The reason why the rotation of the pulsator 14 is started after the intermediate valve 21 is opened for 10 seconds is as follows. That is, if the pulsator 14 is rotated from the beginning, the pulsator 14 will rotate without sufficient water, resulting in idling, which will adversely affect the motor 16 and cause water to scatter around. When 10 seconds elapse after opening the intermediate valve 21, the washing liquid in the fully automatic washing tub 4 side flows into the non-automatic washing tub 5 side due to the water level difference, so that the pulsator 14 can fully exert its pumping action. .

In the case of reusing the washing liquid, if the fully automatic course key 49 is also pressed, the fully automatic washing tub 4 side will proceed to rinsing and spin-driving operations after the washing liquid is transferred, but the non-automatic washing tub 5 side will proceed to the standard water flow start key 42. Otherwise, the operation will not be performed unless the soft water flow start key 43 is pressed.

When the rinsing liquid automatic reuse key 50 is pressed, the rinsing liquid in the fully automatic washing tub 4 side is transferred to the non-automatic washing tub 5 side after the rinsing operation is completed.

When the manual reuse key 51 is pressed, the operating status of the motors 9 and 16 of both washing tubs, the operating status of the water supply valves 28 and 29, and the operating status of the water level switch on the fully automatic washing tub 4 side are checked. As a result, both the motors 9, 16
is stopped, both water supply valves 28 and 29 are closed, and the pulsator 14 on the non-automatic washing tub 5 side rotates only when the microcomputer determines that there is liquid up to the specified water level on the fully automatic washing tub side. , the liquid in the fully automatic washing tub 4 side is transferred to the non-automatic washing tub 5 side.

As described above, the present invention is economical because the washing liquid once used in the fully automatic washing tank can be reused in the semi-automatic washing tank, and when the washing key is pressed at the same time, the fully automatic washing tank and the semi-automatic washing tank water is supplied at the same time to
After that, the operations proceed automatically in parallel, so there is no need to manually operate the water supply valve, and although the operation time on the fully automatic washing tank side is longer for the final spin-drying process, it is almost the same. Since the operation of both washing tubs is completed at the same time, it becomes easier to perform post-processing such as hanging clothes on the clothesline.
