The supplied tap water flows into the pre-filter 24 via the first check valve 22 to remove solid particles such as rust contained in the tap water. The water flowing out of the pre-filter 24 flows into the ion exchange resin tank 30 in one of the two tanks via the water amount integrating meter 28. The other ion exchange resin tank 30 is connected to a brine tank 32 and is regenerated with saline. The water amount integrator 28 integrates the amount of water to be treated in the ion exchange resin tank 30, and when a predetermined amount of water is reached, one ion exchange resin tank 30 is connected to the brine tank 32 and the other ion exchange resin tank 30 is connected. Purifies the water from the prefilter 24. As described above, the ion exchange resin tank 30 is configured with two ion exchange resin tanks 30 and the water is alternately purified, so that the ion exchange resin tank 30 without water purification is
It can be connected to the brine tank 32 and regenerated,
Maintenance of the ion exchange resin tank 30 can be omitted.

The water from which the cations have been removed in the ion exchange resin tank 30 flows into the carbon filter 34, the chlorine ions contained in the water are removed by adsorption, and the water flows out of the carbon filter 34. The outflowing water is stored in the holding tank 36. Water flowing out of the outlet (not shown) of the holding tank 36 flows into the second check valve 64 of the high pressure section 14 and the second pump 42 of the intermediate pressure section 12. The water flowing into the second pump 42 is boosted in pressure, but since the first motor drive valve 46 is in the open state,
The first return flow path 44 via the first motor drive valve 46.
Is returned to the holding tank 36. As a result, sufficient osmotic pressure is not applied to the reverse osmosis membrane unit 52, so that water does not pass through the reverse osmosis membrane unit 52.

As a result, the water pressure of the water flowing out from the reverse osmosis membrane unit 52 (which can be monitored by the third water pressure gauge 56) is
Since the water pressure is lower than the water pressure flowing out from the outlet of the holding tank 36, the water flowing from the holding tank 36 through the second check valve 64 flows into the first pump 62 of the high-pressure unit 14. That is, the water is not purified by the reverse osmosis membrane unit 52. The water flowing into the first pump 62 is boosted in pressure and is injected into the second motor drive valve 70. Since the flow path of the second motor drive valve 70 is switched to the first unloader 72 side, water flows into the first unloader 72. The first unloader 72 returns a part of the inflowing water to the holding tank 36 via the fifth return flow passage 90, and the hose 8 via the fourth check valve 82.
The water pressure of the water injected from No. 8 is adjusted to a predetermined value. Water ejected from the hose 88 can be used to wash the walls of the house, window glass, and the like. The water sprayed for cleaning removes solid particles such as rust, cations such as calcium and magnesium ions, and chlorine ions, so when water drops on the wall of a house or window glass are dried during cleaning. In addition, there is no cloudiness.

Further, when cleaning a window glass or the like incorporating a glass having higher transparency, first, the controller 18 is used.
The third switch 1 in the power unit 16 by operating the switch
12, the second motor 110 is operated to reduce the rotation speed of the engine 92, and the amount of water injected from the first pump 62 and the second pump 42 is reduced. After that, the switch of the controller 18 is further operated to switch the second switch 100 in the power unit 16 to the second position. As a result, the first motor drive valve 46 in the intermediate pressure section 12 is closed,
The flow path of the second motor drive valve 70 in the high-pressure unit 14 is switched so that water flows out to the second unloader 74 side. In this state, the water pressurized by the second pump 42 is not returned from the first motor drive valve 46 to the holding tank 36 via the first return flow path 44, but to the reverse osmosis membrane unit 52. The water pressure applied increases and passes through the reverse osmosis membrane unit 52. Output part of the reverse osmosis membrane unit 52,
Regarding the water pressure of the input part of the first pump 62 and the output part of the second check valve 64, a part of the water boosted by the first pump 62 passes through the second unloader 74 and then the first pump 62. 6
Since it is returned to the second input portion, the water pressure from the holding tank 36 added to the input portion of the second check valve 64 becomes higher. Therefore, since the water from the holding tank 36 does not flow into the input portion of the first pump 62, only the water flowing out from the reverse osmosis membrane unit 52 flows into the first pump 62. The water whose pressure has been increased by the first pump 62 is injected into the second motor drive valve 70, and the water pressure is adjusted by the second unloader 74 so that the water pressure becomes a predetermined value. It is injected from the hose 88 to the outside via the. By passing through the reverse osmosis membrane unit 52, water removes anions and the like in the water that have not been adsorbed by the carbon filter 34. Therefore, the injected water is further reduced in impurities, so that even if a highly transparent glass product or the like is washed, turbidity or the like does not occur after drying.

When the cleaning work is completed, the engine 92 is stopped and the driving of the first pump 62 and the second pump 42 is stopped. Next, the first switch 98 in the power unit 16 is turned on, an AC voltage is supplied to the first motor 84, the first motor 84 is operated, the hose 88 is rewound, and the whole operation is completed. In this way, the operator who injects water and cleans the wall of the house and the window glass, etc., purifies the water to be used by selecting whether or not to use the reverse osmosis membrane unit with the controller while performing the cleaning work. The degree can be changed. Further, since there is an engine that uses gasoline or the like as a fuel and the generator can generate electric power to drive the first and second pumps, it is not necessary to supply power from the outside. In the path where water is boosted, a regulator valve that adjusts the water pressure and a water pressure gauge that monitors the water pressure are installed, so it is possible to prevent abnormalities in each part, and when an abnormality occurs, immediately detect the abnormal place. It can be specified and repair time can be shortened.

Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and two prefilters and two carbon filters are provided, and one filter is provided. It is needless to say that many modifications can be made without departing from the spirit of the invention, for example, by using the other filter when exchanging the device so that the device can be operated effectively.

[0023]

When the water treatment device according to the present invention is used, since water such as tap water passes through the prefilter, the ion exchange resin tank, and the carbon filter, solids such as rust contained in the tap water and the like. Particles and various ions can be removed as much as possible. Therefore, solid particles, various ions, and the like are extremely small in the water sprayed onto the wall and the like, and traces of water droplets do not remain on the wall where the washed water is dried. Since the constituent members such as the ion-exchange resin tank are incorporated in the frame body and are made compact, there is a remarkable effect that they can be easily carried by a small automobile.
