Description

[Detailed Description of the Invention] The present invention is a system in which washing liquid or rinsing liquid used once in a fully automatic washing tub is transferred to a non-automatic washing tub for reuse, when both washing tubs are not in use. The rinsing liquid is transferred only when the rinsing liquid is removed.

Various ideas have been proposed to transfer the washing liquid or rinsing liquid once used in a fully automatic washing tub to a non-automatic washing tub for reuse, but when the reuse key is pressed, the usage state of both washing tubs is changed. Because the liquid is transferred regardless of the condition, the liquid in the non-washing tub may overflow, the rinsing liquid may be contaminated with washing liquid, the washing liquid may become diluted, or if the fully automatic washing tub is in operation. As the water level in the fully automatic washing tub decreases due to liquid transfer, the pulsator rotates faster.
There were drawbacks such as damaging clothes.

In order to eliminate such drawbacks, the present invention checks the usage status of both washing tubs when the manual reuse key is pressed, and only when both tubs are not in use, liquid from the fully automatic washing tub is transferred to the non-automatic washing tub. It was moved to the side.

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. Note that here, non-automatic means not fully automatic, and includes those that proceed automatically up to the rinsing process before dehydration. 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 accommodated therein, and a pulsator is installed at the bottom of the inner tub. 8 exists. Reference numerals 9 and 10 denote a motor and a clutch attached to the bottom of the washing tub 4. The rotational force of the motor 9 is transmitted to the clutch 10 via pulleys 11 and 12 and a belt 13, and by switching the clutch, the rotational force is increased. It is transmitted to the pulsator 8 for washing, and is transmitted to the inner tank 7 for dehydration.

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

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 light emitting diode is lit using the bit segment signal. Also, 4 bits of the timing signal are used to read data from the keyboard 2. 32 indicates switch group, 50/60
The open/close states of the Hz selector 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 is controlled by an 8-bit signal output from the microcomputer 30.
Non-automatic washing tank side water supply valve 28 and non-automatic side motor 1
6, and the fully automatic side water supply valve 29, the fully automatic side motor 9, the non-automatic side drain valve 24, the fully automatic side drain valve 23, and the 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 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, . . . that constitute 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 you press 9, 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. When the stop key 44 is pressed, the motor 16 is stopped 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. In addition, stop key 4
Even after pressing 4, 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. good.

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.

The simultaneous washing key 47 is used to perform washing in both washing tubs at the same time. When this washing key is pressed and 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. 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 side washing tank stops operating, but
The fully automatic side 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 in the fully automatic washing tub 4 is completed. FIG. 4 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. .

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.

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 microcomputer 30 determines that there is liquid up to the specified water level in the fully automatic washing tub.
Washing liquid or rinsing liquid is transferred from a fully automatic washing tub 4 to a non-automatic washing tub 5. That is, first, the intermediate valve 21 is opened to transfer some of the liquid in the fully automatic washing tub to the non-automatic washing tub, and after 10 seconds, the pulsator 1 in the non-automatic washing tub is opened.
4, the liquid is forcibly transferred by the pump action of the back blade 15, and after another 2 minutes, the pulsator is stopped and the intermediate valve 21 is closed to complete the transfer of the liquid. FIG. 5 is a flowchart.

As described above, in the present invention, when the manual reuse key is pressed, the usage status of the fully automatic washing tub and the non-automatic washing tub is checked, and the liquid is transferred only when both washing tubs are not in use. There is no possibility that the liquid in the non-automatic washing tub where the liquid is sent will overflow, the washing liquid will not be diluted with the rinsing liquid, or the rinsing liquid will not be contaminated with the washing liquid, and the pulsator will not run in the fully automatic washing tub that sends the liquid. There is no dry running, and errors in use can be avoided.
