The cleaning means is controlled so as to discharge the one ionized water, and after the cleaning, the other one of the alkaline water and the acidic water is output from the ionized water supply means. In this case, one of the ionic water may be supplied to the cleaning unit before starting the cleaning, and the other may be supplied while the one of the ionic water is already supplied to the cleaning unit. is there. In the rinsing mode, the ionic water supply unit is controlled so as to supply the other ionic water to the cleaning unit after the rinsing, and the other ionic water is discharged from the cleaning unit. The other ionic water may be supplied to the washing unit until the other ionic water is stored to some extent, and then the other ionic water may be discharged. In this case, the other ionized water may be added to the cleaning means in an amount substantially corresponding to the discharged amount. In the cleaning mode, one of the ionic water discharged from the cleaning means and the other ionic water output from the ionic water supply means are stored in a tank. Both ionized waters can be combined before reaching the tank, or they can be combined in the tank. In the rinsing mode, the other ionic water discharged from the cleaning means is stored in a tank. The water from this tank is filtered and supplied to the ionic water supply means by the filter.

In this case, in the cleaning mode, one of the alkaline ionized water and the acidic water suitable for the property of the object to be cleaned is selected and supplied to the cleaning means. Washing is performed with the one ionized water. One of the ionic water used for the washing is combined with the other ionic water and neutralized. In the rinsing mode, the other ionic water is supplied to the cleaning means to neutralize the one ionic water attached to the object to be cleaned. As described above, since the object to be cleaned is washed without using the dry cleaning solvent, when the object to be cleaned is clothing, skin wear does not occur to a wearer of the clothing. Further, since no detergent is used, there is no problem of environmental and pollution, and one of the ionic water adhered by the washing is neutralized, so that the object to be washed is not damaged. In the cleaning mode, one ion water and the other ion water stored in the tank are neutralized, and in the rinsing mode, one ion water adheres to the object to be cleaned, and the object to be cleaned exists. Since the other ionic water is supplied to the cleaning means, both the object to be cleaned and the other ionic water are neutralized. The other neutralized ionized water is supplied to the tank. In addition, by being stored in the tank,
More neutralization is promoted. The water in this tank is supplied to the filter, filtered, and supplied to the ionic water supply means as raw water. Therefore, resource saving can be achieved.

Which is connected to the discharge passage 5 via a stopper 22b.

The alkaline ion water conduit 20a and the acidic water conduit 20b are connected to switching means, for example, an input port of a switching valve 24. The switching valve 24 has two output ports, one of which is connected to the washing tub 2 a and the other of which is connected to the discharge passage 5. The switching valve 24 supplies the alkaline ionized water from the alkaline ionized water conduit 20a to the washing tub 2b via the washing machine conduit 25, or supplies the alkaline ionized water to the discharge passage 5 via the neutralizing conduit 26. Alternatively, the acidic water from the acidic water passage 20b is supplied to the washing tub 2b through the washing machine conduit 25 or to the discharge passage 5 through the neutralizing conduit 26.

A surge tank 30 is provided at an end of the discharge passage 5. The sewage that has passed through the surge tank 30 is supplied to a sewage tank 32 via a passage 31. In the sewage tank 32, a sewage passage 3 in which a pump 34 is provided halfway is provided.
6 is attached. The sewage pumped by the pump 34 is supplied to a filter 38. Filter 3

The fourth layer 38d is a hollow filter for removing all remaining contaminants. Since the filter 38 having a plurality of layers having different properties is used, various contaminants can be removed.

The water filtered by passing through the filter 38 is supplied to a magnetic water treatment device 42 through a passage 40. The magnetic water treatment apparatus 42 removes slime and scale attached to the passage 40 as disclosed in, for example, Japanese Patent Application Laid-Open No. 6-343973. The water that has passed through the magnetic water treatment device 42 is supplied to the ion water generator 6 via the electromagnetic on-off valve 44 and the check valve 46, and is reused as raw water for the ion water. Tap water is also supplied to the ionized water generator 6 via a water tap 48, an electromagnetic on-off valve 49, and a check valve 50. Reference numeral 52 denotes a stopper for the sewage tank 32, which is opened when the sewage tank 32 is cleaned and inspected.

The ion water generator 6, the discharge electromagnetic opening / closing valve 4, the alkaline ion water air electromagnetic opening / closing valve 18a, the acidic water air electromagnetic opening / closing valve 18b, the switching valve 24, the pump 34, the electromagnetic opening / closing valves 44 and 49 are control means, For example, it is controlled by a microcomputer 28.

The control of the ion water generator 6 is performed, for example, as shown in FIG. As a premise of the control, the water tap 48 and the electromagnetic on-off valve 49 are opened, and the water is supplied to the ionized water generator 6.
Is supplied to The solenoid on-off valve 44 is closed.
Although not shown, the first and second alkaline water tanks 14 and the acidic water tank 16 are located at different heights.
Sensors are provided. The first sensor is mounted at a lower position than the second sensor.

When the first sensor stops detecting the liquid level, the controller 28 operates the ionized water generator 6 (step S2). Thereby, the alkali ion water tank 14 of the alkali ion water and the acid water and the acid water tank 1
Storage at 6 is started. Next, it is determined whether the second sensor is turned on, that is, whether a predetermined amount of alkaline ionized water or acidic water is stored in the alkaline tank 14 or the acidic water tank 16 (step S4). If it is not determined that the second sensor is on, step S4 is repeated until it is turned on. When the second sensor is turned on, the ion water generator 6 is stopped (Step S6). Therefore, when the amount of the alkaline ionized water or the acidic water decreases, the alkaline ionized water and the acidic water are automatically generated. The pH of the alkaline ionized water is 9 to 1
The acidic water has a pH of 4 to 6.

Also, a discharge electromagnetic on-off valve 4, an alkali ion water air electromagnetic on-off valve 18a, an acidic water air electromagnetic on-off valve 1
The washing process and the rinsing process are executed by the control of the switch 8b and the switching valve 24. In the washing process, basket 2 in washing tub 2a
The laundry put in b is washed. Clothing such as cotton and acrylic is used as the laundry. The switching valve 24 is switched to supply the alkaline ionized water to the washing tub 2a, and the discharge electromagnetic on-off valve 4 is closed.

When the washing start signal is supplied to the control unit 28, as shown in FIG. 3, the alkaline ionized water air electromagnetic on-off valve 18a is opened (step S8). Thus, the alkaline ionized water is supplied from the alkaline ionized water tank 14 to the washing tub 2a via the switching valve 24. Subsequently, the washing tub 2a or the alkaline ionized water tank 1
It is determined whether or not the sensor provided in No. 4 has been turned on (step S10). That is, it is determined whether a predetermined amount of alkaline ionized water has been supplied to the washing tub 2a. If the sensor is not turned on, step S8 until the sensor is turned on,
S10 is repeated. When turned on, the alkaline ionized water air electromagnetic on-off valve 18a is closed, and the supply of the alkaline ionized water is stopped (step S12). Next, it waits for the passage of time until the alkaline ionized water sufficiently permeates the clothes (step S14). Thereafter, although not shown, the rotation of the car 2b is started.

In parallel with this rotation, the one-shot operation of the alkaline ion water air electromagnetic on-off valve 18a is performed (step S16). That is, after the alkaline ionized water air electromagnetic on-off valve 18a is opened for a predetermined time, it is closed. As a result, a predetermined amount of alkali ion water is added to the washing tub 2a.

Subsequently, the switching valve 24 is switched to supply the acidic water to the discharge passage 5 (step S18). Then, the acidic water air electromagnetic on-off valve 18b and the discharge electromagnetic on-off valve 4 are simultaneously operated by one shot (step S20). That is, the acidic water air solenoid on-off valve 1
8b and the discharge electromagnetic on-off valve 4 are closed after being opened. As a result, the acidic water is discharged to the discharge passage 5, and the alkaline ionized water in the washing tub 2a is discharged from the discharge electromagnetic on-off valve 4 to the discharge passage 5 to neutralize the alkaline ionized water.

The discharge amount of the alkaline ionized water from the discharge electromagnetic on-off valve 4 is set to substantially the same amount as the alkaline ionized water added to the washing tub 2a by the one-shot operation of the alkaline ionized water air electromagnetic on-off valve 18a. ing. During the opening time of the acidic water air electromagnetic on-off valve 18b, the amount of acidic water required to neutralize the alkaline ionized water discharged to the discharge passage 5 by opening the discharge electromagnetic on-off valve 4 is discharged to the discharge passage 5. It is set to be able to. Therefore, the opening time of the acidic water air electromagnetic on-off valve 18b does not always coincide with the opening time of the discharge electromagnetic on-off valve 4.

Subsequently, the switching valve 24 is switched so that the alkaline ionized water can be supplied to the washing tub 2a (step S22). Then, it is determined whether the above-described one-shot operation has been performed a predetermined number of times, for example, 10 times (step S24). If it is determined that the processing has not been repeated ten times, steps S16 to S24 are repeated until the result of the determination in step S24 becomes YES. If it is determined in step S24 that the processing has not been performed ten times, step S16 may be started immediately after a predetermined time has elapsed without immediately starting step S16.

During the washing, as the dirt comes off from the laundry, the pH value of the alkaline ionized water in the washing tub 2a changes, the washing effect decreases, and the dirt can re-attach to the laundry. There is. In order to cope with this, in this cleaning device, alkaline ionized water is added to the washing tub 2a, and old alkaline ionized water is discharged from the washing tub 2a by an amount substantially corresponding to the added amount. Therefore, even if the washing progresses, the PH value of the alkaline ionized water in the washing tub 2a is maintained substantially at the initial value, the washing effect is improved, and reattachment of dirt is prevented. Moreover, since such an operation is repeatedly performed, the pH value of the alkaline ionized water in the washing tub 2a can be maintained substantially at the initial value during the washing.

The alkaline ionized water discharged from the washing tub 2a is neutralized by being mixed with the acidic water in the discharge passage 5, and further neutralized by the surge tank 30 more reliably.

If the result of the determination in step S24 is YES, that is, if it is determined that the washing process has been completed, the switching valve 24 is switched so as to discharge the acidic water to the discharge passage (step S26). Next, the discharge electromagnetic on-off valve 4 is opened, and the acidic water air electromagnetic on-off valve 18b is opened (step S28). Thereby, the alkaline ionized water in the washing tub 2a is discharged to the discharge passage 5. This alkaline ionized water is neutralized in the discharge passage 5 by the acidic water from the switching valve 24, and is further reliably neutralized by the surge tank 30. Although not shown, step S
When the determination result at 24 is yes, the rotation of the car 2b is stopped. When all the alkaline ionized water in the washing tub 2a is discharged, the acidic water air electromagnetic on-off valve 1
8b is closed.

Next, when the rinsing start signal is supplied to the control unit 28, as shown in FIG. 4, the discharge electromagnetic on-off valve 4 is closed (step S30), and the rinsing frequency counter advances by one (step S32). . However, this counter is initially reset.

Subsequently, the switching valve 24 is switched so that the acidic water is supplied to the washing machine 2 (step S3).
4). Subsequently, the acidic water electromagnetic on-off valve 18b is opened to start supplying the acidic water to the washing tub 2 (step S36). Next, it is determined whether a sensor provided in the washing tub 2a or the acidic water tank 16 has been turned on, that is, whether a predetermined amount of acidic water has been supplied to the washing tub 2a (step S38). If the predetermined supply is not performed, steps S36 and S38 are repeated until a predetermined amount of supply is performed. When the supply of the predetermined amount is performed, the acidic water electromagnetic on-off valve 18b is closed (Step S40), and the supply of the acidic water is stopped.

In this state, although not shown, the car 2b
Is rotated, and rinsing with acidic water is performed. Since the previous washing is performed with alkaline ionized water, the clothes are neutralized by rinsing with acidic water.

Next, it is determined whether or not the discharge start signal has been supplied (step S42).
Step S42 is repeated. When a time suitable for ending the rinsing has elapsed, a discharge start signal is supplied, the discharge electromagnetic on-off valve 4 is opened (step S44), and the neutralized acidic water is discharged from the washing tub 2a into the discharge passage 5. Is started, and further neutralized by the surge tank 30.

Next, the acidic water air electromagnetic on-off valve 18b is opened (Step S46), and while the acidic water is being discharged from the washing tub 2a, the acidic water is additionally supplied to the washing tub 2a. As a result, the clothing is sterilized.

Subsequently, it is determined whether the sensor provided in the washing tub 2a or the sensor provided in the acidic water tank 16 is ON, that is, whether the acid water in the washing tub 2a has decreased to a predetermined amount (step). S48). If not, steps S46 and S48 are repeated until it does. When it decreases, the acidic air electromagnetic on-off valve 18b is closed and the discharge electromagnetic on-off valve 4 is closed (step S50).

Then, it is determined whether the number of times of rinsing is a predetermined number, for example, two (step S52). If the number of times of rinsing has not reached the predetermined number, the process is repeated from step S32. If the predetermined number of times has been reached, the rinsing number counter is reset (step S54), and the rinsing step ends.

The water neutralized as described above is further neutralized while being stored in the surge tank 30.
Discharging this water as is is wasting resources. Therefore, it is conceivable that this water is recirculated to the ion water generator 6 to save resources. However, this water is dirty because it is used for washing. In order to remove the dirt, the water in the surge tank 30 is passed through the filter 38 and the magnetic water treatment device 40.

That is, although not shown, the sewage tank 32 is provided with a water level sensor. When a predetermined amount of sewage is stored in the sewage tank 32, the control unit 28 closes the solenoid valve 49 and stops the supply of tap water to the ionic water generator 6 based on a signal from the water level sensor. And pump 3
4 is operated, and the electromagnetic switching valve 44 is opened. Thereby, the sewage is pumped up from the sewage tank 32 by the pump 34, passes through the filter 38, and is filtered.
Further, scale and slime of the water that has passed through the filter 38 are removed by the magnetic water treatment device 40, and the water is supplied to the ionized water generator 6.

The operation of the pump 34 and the operation of the solenoid on-off valve 4
The opening of the washing machine 4 is performed only when the washing machine 2 is operating. When the washing machine 2 is stopped, the pump 34 is also stopped, and the electromagnetic on-off valve 44 is also closed.

In the above embodiment, the one-shot operation is performed ten times in the washing process. However, the number of the one-shot operations can be arbitrarily changed depending on the soiling of the laundry. Further, in the rinsing step, rinsing is performed twice, but the number of times may be arbitrarily changed.
The alkaline ionized water used for washing is
Although cold water was used as it is, the alkaline ionized water tank 1
The heater 4 may be provided with a heater to be used after warming. The use of warm water in this manner has a high effect of removing dirt. For example, the temperature to be warmed may be from room temperature to about 80 degrees Celsius.

In the above embodiment, the laundry is made of cotton,
Acrylic and the like were used, but in addition to these, those of vegetable or chemical fiber can also be used. In addition, when clothes made of wool or other animal fibers are washed with alkaline ionized water, the fibers may shrink. Therefore, at the time of washing, acidic water is used, and while adding the acidic water for a short time, the acidic water is discharged from the washing tub 2a to the discharge passage 5, and at the same time, the alkaline ionized water is supplied to the discharge passage 5, and the washing tub 2a When neutralizing the acidic water, and discharging the acidic water used for washing from the washing tub, the alkaline ionized water is discharged to the discharge passage 5,
It may be neutralized. In this case, rinsing is performed with alkaline ionized water to neutralize the laundry being acidic. However, it is desirable that the final rinsing performed in steps S44 to S50 be performed with acidic water and sterilized.

In the above-described embodiment, in the washing step, the alkaline ionized water is discharged from the washing tub 2a to the discharge passage 5 while the alkaline ionized water is added for a short time, and the acidic water is discharged to the discharge passage 5 at the same time. Although the supply and neutralization of the alkaline ionized water from the washing tub 2a were performed, the discharge electromagnetic on-off valve 4 was closed, and the washing tub 2a was added by adding the alkaline ionized water.
, The alkaline ionized water may automatically overflow into the discharge passage 5, and the acidic water may be supplied to the discharge passage 5 by the overflow amount. As the washing machine 2, a drum type in which the basket 2b rotates is used.
A vertical washing machine can also be used. Further, in the above embodiment, the electromagnetic on-off valve is used, but another valve may be used instead. Further, in the above embodiment, since the switching valve 24 is used, the passage from the switching valve 24 to the washing machine 2 is only the conduit 25 for the washing machine, and the passage from the switching valve 24 to the discharge passage 5 is provided. There is an advantage that only the neutralization passage 26 is provided, but when a passage to the washing machine 2 and a passage between the discharge passages 5 may be respectively added,
Instead of the switching valve 24, a passage having an on-off valve between the washing machine 2 and the alkali ion water outlet 14c, a passage having an on-off valve between the washing machine 2 and the acidic water outlet 16c, the discharge passage 5 A passage having an on-off valve between the alkaline ionized water outlet 14c, the discharge passage 5 and the acidic water outlet 16c.
And a passage having an opening / closing valve may be provided between them, and the opening / closing of each of these opening / closing valves may be controlled.

In the above-described embodiment, laundry is used as an object to be washed. However, the present invention is not limited to this, and can be used for washing various items such as linen, tableware, and cooking utensils. When washing dishes and cooking utensils, for example, an automatic dishwasher may be used instead of the washing machine. Also,
In the above embodiment, sterilization was performed by adding acidic water to the washing tub 2a at the end of the rinsing step, but this is not necessary in some cases.

In the above embodiment, the magnetic water treatment apparatus 40 is provided on the outlet side of the filter 40. However, the magnetic water treatment apparatus 40 may be provided on the inlet side, for example, provided at the inlet or outlet of the surge tank 30. Is also good.

[0048]

As described above, according to the present invention, when the object to be washed is, for example, laundry, the object to be washed is washed without using a dry cleaning solvent. It does not cause any environmental or pollution problems because it does not cause skin damage and does not use detergent. In addition, the ionic water used for washing and rinsing is neutralized, filtered by a filter, and used again as raw water for generating ionic water, so that resource saving can be achieved. Further, by using a magnetic water treatment apparatus, water to which scale and slime are not attached can be used as raw water.
