Description

[Detailed description of the invention] The present invention installs a fully automatic washing tub and a non-automatic washing tub side by side, and transfers the washing liquid or rinsing liquid used in the fully automatic washing tub to the non-automatic washing tub and reuses it. In a washing machine, the transfer is stopped when a non-automatic washing machine is in use to prevent washing liquid or rinsing liquid from overflowing.

In a washing machine that transfers the washing liquid or rinsing liquid once used in the fully automatic washing tub to a non-automatic washing tub for reuse, if the washing liquid or rinsing liquid is transferred even though the non-automatic washing tub is in use. During washing, the liquid may become diluted, and during rinsing, the clothes may become soaked with the washing liquid again, or the liquid may overflow.

The present invention solves the above drawbacks by first checking whether the non-automatic washing tub is in use when the washing liquid reuse key or the rinsing liquid reuse key is pressed, and transferring the washing liquid only when the non-automatic washing tub is not in use. This is something that we are trying to resolve. Note that "non-automatic" means not fully automatic, and includes those that automatically perform rinsing before dehydration.

The present invention will be explained below based on the drawings. 1 is a washing machine, and inside the machine frame 3 which has a keyboard 2 on the top surface,
A fully automatic washing tub 4 and a non-automatic washing tub 5 are provided. On the other hand, the fully automatic washing tub 4 is elastically suspended by a plurality of hanging rods 6, and an inner tub 7 having a large number of dehydration holes is housed inside the tub. A pulsator 8 is present. 9,1
0 is a motor and a clutch installed at the bottom of the washing tub 4, and the rotational force of the motor 9 is transmitted by a pulley 11,
12 and a belt 13 to the clutch 10, and by switching this clutch, the rotational force is transmitted to the pulsator 8 for washing or to the inner tub 7 for dewatering.

On the other hand, there is also a pulsator 14 at the bottom of the non-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 5 and 4.
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, 4 bits of the timing signal are used to read data from the keyboard 2. Reference numeral 32 indicates a switch group, and the open/close states of the 50/60 Hz changeover switch, lid switch/safety switch, and liquid level switch are input to the microcomputer 30 in 4 bits. 3
3 is a group of AC control elements, and a microcomputer 3
The 8-bit signal output from 0 causes the non-automatic washing tub side water supply valve 28, the non-automatic side motor 16, the fully automatic side water supply valve 29, the fully automatic side motor 9, the non-automatic side drain valve 24, and the fully automatic side to be activated. Drain valve 23 and intermediate valve 2
1 is 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 non-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 non-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 the time up key 38 is pressed, each light emitting diode will light up sequentially from 1 minute to 10 minutes at 0.5 second intervals, and when the time up key 38 is released, no more light emitting diodes will light up. Therefore, it is possible to set the time in minutes within the range of 1 to 15 minutes. Also time down key 3
When 9 is pressed, the lit light emitting diodes 37... turn off one after another at 0.5 second intervals.

When the water supply key 40 is pressed, water is supplied to the non-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. It's okay.

The simultaneous water supply key 45 is a key for simultaneously supplying water to both the fully automatic washing tub 4 and the non-automatic washing tub 5. When this key is pressed, the water supply valves 29 and 28 to both washing tubs 4 and 5 are activated. 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 level in both washing tubs 4 and 5 will be the same. Water level can be controlled. At this time, the light emitting diode on the course display board 46 shown in FIG. 5, which indicates simultaneous water supply, lights up.

The simultaneous washing key 47 is used to perform washing in both washing tubs at the same time, and when this washing key is pressed, the light emitting diode for simultaneous washing display on the course display board 46 lights up. Thereafter, when the start key 48 is pressed, the water supply valves 28 and 29 are opened to supply water to both washing tubs at the same time, and when water is supplied to a predetermined water level, the pulsators 8 and 14 of both washing tubs rotate simultaneously to perform a washing operation. When washing is finished, the non-automatic washing tub stops operating, but the fully automatic washing tub continues to perform spin-drying and rinsing operations.

49 is a washing liquid automatic reuse key, and when this key is pressed, the washing liquid is transferred to the non-automatic washing tub 5 side after the washing operation is completed in the fully automatic washing tub 4.
Figure 6 shows the operation in a flowchart.When the washing operation on the fully automatic washing tub 4 side is completed,
Whether or not the motor 16 on the non-automatic washing tub 5 side is operating;
Also, check whether the water supply valve 28 on the non-automatic washing tub side 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, the light emitting diode for washing liquid reuse on the course display board 46 in FIG. is turned on, a time count 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 causes the fully automatic washing tub 4 to rotate.
The side washing liquid is passed through the communication pipe 20 to the non-automatic washing tub 5.
Move to the side. 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. intermediate valve 2
The reason why the pulsator 14 starts rotating after opening the pulsator 1 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.
10 seconds 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 due to the water level difference.
Since the water flows to the side, the pulsator 14 can sufficiently exert its pumping action.

When the fully automatic course key 50 is also pressed in the case of reusing the washing liquid, 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. Incidentally, when the fully automatic course key 50 is pressed, all the light emitting diodes on the program timer display board 51 shown in FIG. 4 light up and turn off sequentially from the stroke that has been completed.

When the rinse liquid automatic reuse key 52 is pressed, the rinse 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 53 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. FIG. 7 is a flowchart.

As described above, when the liquid in the fully automatic washing tub is automatically transferred to the non-automatic washing tub after the washing process or rinsing process is completed, the present invention checks whether the non-automatic washing tub is in operation or not. Since the liquid is transferred only when the machine is not in operation, the washing liquid in the non-automatic washing tub may become diluted with rinsing water, or the rinsing liquid in the non-automatic washing tub may become contaminated with washing liquid, or The liquid on the automatic washing tub side does not overflow, and there is no possibility of mistakes in use.
