In this state, the pump 73 is operated to drain the water in the bathtub 68 into the second branch pipe 71 and the first water supply valve 35a. The water is supplied into the water tank 3 via. When the detection unit 47 confirms that there is no water in the bathtub 68, the first water supply valve 35a is opened from the faucet 1 to the water tank 3 side, and water is supplied from the faucet 1 to the water tank 3 (step S-5). Then, the detection unit 47 checks whether or not the water in the water tub 3 has reached the amount of washing water (step S-6).

After the water supply for washing is completed, the water used for the next rinse is stored in the bathtub 68, or the wastewater after the washing is temporarily stored and the wastewater other than the wastewater is stored, depending on the setting stored in the storage unit 14. It is determined whether to discharge at the time (step S-7). When the water to be used for the next rinse is stored in the bathtub 68, the control unit 12 opens the first water supply valve 35a from the faucet 1 to the second branch pipe 71 side, and connects the second water supply valve 71a to the faucet 1 , And the second drain valve 70a is closed toward the bathtub. Further, the first drain valve 45a is opened from the water tank 3 toward the sewer. In this way, tap water for rinsing is introduced into the bathtub 68 from the faucet 1 and stored therein (step S-8), and drainage after the washing process is directly drained from the water tank 3 to the sewer.

When rinsing water is supplied to the water tank 3, the control unit 12 sets the second drain valve 70 a to the bath tank 68.

When the water to be used for the next rinse is not stored in the bathtub 68, the first drain valve 45a is opened from the water tub 3 to the bathtub 68 after the washing process is completed, and the second drain valve 70a is set to the first drain valve 70a. It opens to the bathtub 68 side from the drain valve 45a. In this case,
The washing water used in the washing process is discharged to the bathtub 68 side.
At that time, the washing water is supplied to the bathtub 6 at a position lower than the water tub 3.
8 so that it can be stored in the bathtub 68. The control unit 12 opens the first drain valve 45a from the water tub 3 toward the bathtub 68, and connects the second drain valve 70a to the first drain valve 45.
When the second water supply valve 71a is opened from the pump 73 to the bathtub 68 side, the washing water used in the washing process flows to the bathtub 68 side by the pump 16, and the bathtub 68 is opened.
Is relatively higher than the position of the water tub 3,
Can be stored inside. After the drainage of the washing is completed, the washing water that has flowed and stored in the bathtub 68 moves the second drain valve 70a from the bathtub 68 to the first drain valve 45a side, and moves the first drain valve 45a from the bathtub 68 to the sewer side. By opening, while the washing machine is performing another process, it is discharged to the sewer (step S-9).

After the end of the rinsing process, the control unit 12 determines whether to discharge or store the rinsing water of the last rinsing process according to the storage in the storage unit 14. At the time of draining, the first and second drain valves 45 are used to drain the water from the bathtub 68 during the next step in the same manner as the washing water and the first rinsing water.
When opening and storing a and 70a, the first and second drain valves 45a and 70a are closed. According to the present embodiment, since a spare tank is not used, space can be effectively used, and water can be supplied from the bathtub at the time of initial water supply, so that the water supply time can be shortened and bath water can be easily used. Further, by setting, the bathtub 68 can be used as a water supply storage spare tank or a drainage storage spare tank, and the washing time can be reduced.

The operation of the present embodiment configured as described above will be described. First, a bathtub 68 is connected by a connecting portion (not shown).
Is connected to the water tank 3. If not connected, the control unit (not shown) opens the first water supply valve 35 a from the faucet 1 to the water tank 3 side.
The drain valve 45a is opened from the water tank 3 to the sewer side, and is operated in the same manner as a normal washing machine. When the bathtub 68 is connected to the water tank 3, the operation is performed as follows. First, at the time of water supply, the control unit opens the first water supply valve 35a from the second branch pipe 71 to the water tank 3 side, and opens the second water supply valve 71a from the pump 73 to the first water supply valve 35a side. , Bathtub 68

May not be provided in the washing machine main body 2. According to this embodiment, the effect of two water tanks can be obtained with one bathtub, and the space can be effectively used because no water storage tank is used.

Embodiment 14 FIG. 23 is a schematic view of a fourteenth embodiment of the present invention. Reference numeral 2 denotes a washing machine, 12 denotes a control unit, 82 denotes an outlet which is attached to the washing machine 2 and is energized according to an instruction of the control unit 12, and 83 denotes a water supply timing by judging a water supply timing during operation of the washing machine 2. A discriminating unit that sends a signal to the control unit 12 at times.

The operation of the present embodiment having the above-described structure will be described. When the control unit 12 receives a signal indicating the water supply timing from the determination unit 83, the control unit 12 starts energizing the outlet 82. In this way, power is supplied to the outlet 82 only at the time of water supply, and there is no difference from a normal commercially available washing machine except that the outlet 82 is attached to the washing machine. From this,
By inserting a plug (not shown) of a commercially available pump into the outlet 82 by an operation of energizing the outlet 82 only at the time of water supply, the pump is automatically turned on at the time of water supply and the pump operates. Water supply is started from a tank (not shown) in which water is stored.

The outlet 82 may be provided at any location such as the upper, lower, front, and back sides of the washing machine as long as the outlet 82 is attached to the washing machine. Therefore, according to the present embodiment, the water in the tank in which the water is stored can be easily reused for washing, the trouble of pumping water can be omitted, and the water supply time can be reduced by simultaneously supplying water from the tank and the faucet. Can be shortened.

Embodiment 15 FIG. 24 is a schematic view of a fifteenth embodiment of the present invention. 82
Denotes an outlet, 12 denotes a control unit, 83 denotes a determination unit, and 47 denotes a detection unit. A container 84 stores water to be used for washing. The shape and the structure of the container 84 are not limited, but may be those only for storing water.

In this embodiment, at the start of water supply, the water supply valve 43a is kept closed, and the water supply valve 43a is closed.
Is controlled by the control unit 12 so that water is not supplied to the
This is different from the fourteenth embodiment. For example, it is assumed that the plug 86 of the water supply pump 85 is inserted into the outlet 82. The water supply capacity of the water supply pump 85 is determined, and the amount of water supply is inevitably determined. Therefore, the water supply time is reduced by simultaneously supplying water from the water supply. If water is supplied by both pumps 85, the effect of water reuse will be diminished. Then, after a certain period of time has elapsed since the start of water supply by the water supply pump 85, water is supplied by both the water supply pump 85 and the water supply, and the amount of water used is reduced as much as possible to increase the water reuse effect. It is.

That is, it is determined whether or not a fixed time has elapsed from immediately after the water supply timing (step S- in FIG. 25).
1) If the time has not elapsed, water is continuously supplied only from the water supply pump 85 (step S-2), and if a predetermined time has elapsed, water is supplied simultaneously by both the water supply pump 85 and the water supply (step S-3). This means that even when the water supply pump 85 is not connected to the outlet 82, water is automatically supplied from the water supply after a certain period of time has elapsed from the water supply timing, so that the washing machine is used even if water is not supplied from the water supply pump 85. be able to.

Further, after a lapse of a certain time from the water supply timing, it is also possible to determine whether or not water is to be supplied from the water supply and water is to be used in combination with the water level of the water tank 3. Since a commercially available pump is used for the water supply pump 85, the combined use of the water supply pump 85 and the water supply is determined based on the amount of water supplied to the water tank 3 in consideration of the difference in the amount of water supplied by the pump. It is. That is, after the water supply timing, the water tank 3 is supplied with water only by the water supply pump 85 (step S- in FIG. 26).
4) After a certain time has elapsed, the amount of water in the water tank 3 is detected (step S-5). Then, when the water amount is equal to or less than the set water amount, the water is continuously supplied by the water supply pump 85, and when the water amount exceeds the set water amount, the water is supplied by using both the water supply pump 85 and the water supply (step S-6).

In the fourteenth embodiment, an outlet is provided in the washing machine, and power is supplied only at the time of water supply.
In the present embodiment, there are two effects of how efficiently the water is supplied to the washing machine in a short time and the amount of tap water used is reduced as follows.

In each of the above embodiments, a bathtub can be used as a spare storage tank in all cases, and in all cases (except when already installed, the same applies to the following). A detection unit for detecting the amount of water in the inside can be provided. Further, in each of the above-described embodiments, in all cases, the water supply storage reserve tank and the bathtub can be detachably mounted, and in this case, a connection portion for detecting a connection state of the storage reserve tank with the water tank can be provided. . The flow of water supply and drainage can be changed depending on the connection state. Further, a partition may be provided in one storage reserve tank or bath tub to have both functions of water supply and drainage.

[0116]

As is clear from the above description, according to the present invention, the following effects can be obtained. In addition,
In the description, the same reference numerals as in the claims are used to describe the effects of each claim. (1) Two storage reserve tanks, water supply and drainage, are provided in addition to the water tank, so that water supply and drainage from the storage reserve tank can be performed when necessary by operating the control unit. After the water supply operation in the rinsing process is completed, water is not supplied to the water supply reserve tank, so that the water supply time and the drainage time can be reduced, and the time required for the entire washing process can be reduced. In addition, by setting using the operation panel, corrosion of water stored in the storage reserve tank can be prevented, water resources can be reused, and energy saving can be realized.

(2) Water can be supplied simultaneously from the water supply storage reserve tank and the water supply, and the operation panel is set so that the water supply to the water supply storage reserve tank is not performed after the water supply operation in the last rinsing process is completed. Therefore, the water supply time can be further reduced. In addition, by setting using the operation panel, corrosion of water stored in the storage reserve tank can be prevented, water resources can be reused, and energy saving can be realized.

(3) The three-way switching from the water supply to the water supply storage reserve tank, from the water supply to the water tank, and from the water supply storage reserve tank to the water tank can be performed by one valve, so that the number of water supply valves can be reduced. Water supply time can be further reduced. Also, depending on the settings on the operation panel,
Water can be stored in the storage reserve tank, water resources can be reused, and energy saving can be realized.

(4) The drainage time can be further reduced because the drainage storage reserve tank and the sewer are configured to be drained simultaneously. In addition, by setting using the operation panel, corrosion of water stored in the storage reserve tank can be prevented, water resources can be reused, and energy saving can be realized.

(5) The three-way switching from the water tank to the drainage storage reserve tank, from the water tank to the sewer system, and from the wastewater storage reserve tank to the sewerage system can be performed with one valve.
The number of drain valves can be reduced, and the drain time can be further reduced. In addition, by setting using the operation panel, washing water can be stored, water resources can be reused, and energy can be saved.

(6) Since water is supplied simultaneously from the water supply storage reserve tank and the water supply, and water is simultaneously drained to the drainage storage reserve tank and the sewer, the water supply / drainage time can be further reduced. In addition, by setting using the operation panel, corrosion of water stored in the storage reserve tank can be prevented, selected water can be stored, water resources can be reused, and energy can be saved.

(7) A single valve can be used to switch the three directions from the water supply to the water supply reserve tank, from the water supply to the water tank, and from the water supply storage reserve tank to the water tank, and from the water tank to the waste water storage reserve tank and from the water tank. Since the three-way switching from the sewer and the drainage storage reserve tank to the sewer can be performed with one valve, the number of water supply valves and drainage valves can be reduced, and the time for water supply and drainage can be further reduced. In addition, by setting using the operation panel, it is possible to prevent corrosion of water stored in the storage reserve tank and store washing water, reuse water resources, and realize energy saving.

(8) Since the water is drained from the water tank by two drain pipes, when the storage reserve tank is connected, the water is apparently drained from the water tank at once and the drainage time is reduced. Can be shortened. Further, since the washing water can be stored, water resources can be reused, and energy saving can be realized.

(9) Since two water supply valves, two drainage valves, and a pump, which can be switched in three directions, are used to supply and drain water by one storage spare tank, space can be effectively used. Also, the washing time can be reduced.

(10) Using two water supply valves, two drainage valves and a pump which can be switched in three directions, the two storage reserve tanks are made to be in the same position so that water can be supplied and drained. Since the system is configured so that water can be drained to the tank and the sewer at the same time, the space can be effectively used, the washing time can be reduced, and the drainage time can be further reduced.

(11) A detection unit for detecting the amount of water in the storage reserve tank is provided, and the control unit controls each valve in response to a signal from the detection unit. Can be performed efficiently and efficiently.

(12) Since the storage reserve tank is detachably mounted and a connection portion for detecting the connection state of the storage reserve tank is provided, the connection state of the storage reserve tank can be automatically determined, and there is no storage reserve tank. In this case, it can be used in the same manner as a normal washing machine.

(13) Since the storage tank for water supply and the storage tank for drainage are formed by providing a partition in one storage preliminary tank, one spare tank can fulfill two roles.

(14) When the water stored in the storage reserve tank is supplied to the water tank by the control means, it is detected that there is no water in the storage reserve tank, or if there is no water supply in the water tank for a predetermined time, Since the water supply valve is controlled so as to supply water from the tap water, the washing machine can be operated without supplying water from the storage reserve tank.

(15) Since the bathtub of the bathroom is used as the storage tank, there is no need to install a dedicated storage tank, and the space can be used effectively, and the remaining hot water in the bath can be easily used to save water resources. Can be used effectively.

(16) Since a judging section for judging the water supply timing and an outlet for starting or stopping energization according to a signal from the judging section are provided, a commercially available pump can be automatically operated. It is exactly the same size as a normal washing machine, and can easily reuse water in a tank in which water is stored. In addition, water can be supplied from a tank and a faucet at the same time, thereby shortening a water supply time.

(17) A judging section for judging that it is water supply timing, an outlet for starting or stopping energization according to a signal from the judging section, a detecting section for detecting the amount of stored water, and a detecting section for determining the amount of water storage A water supply valve that operates to supply water from the water supply to the water tank when the required water amount is not reached, and a control unit that controls the water supply valve are provided, so that a commercially available water supply pump can be automatically operated, and Reuse can be performed easily, and the ratio of the amount of water supplied from the water supply to the amount of water supplied from the container storing the water can be changed, so that energy saving of water can be realized.
