Description

  The present invention relates to a reforming system for water supplied to a bathroom.

Water discharged from a currant or shower provided in the bathroom is generally tap water (see, for example, Patent Document 1). By the way, since tap water contains a lot of dissolved substances such as calcium, magnesium, silicon, etc., when the bathroom is washed with tap water, the tap water remaining in the bathroom evaporates, causing scale dirt in the bathroom. In addition, since tap water contains components necessary for the growth of bacteria, contamination by microorganisms is likely to occur in the bathroom. In addition, tap water containing mineral components generates metal soap, and there is also a problem that the cleaning power of the soap is reduced due to the generation of the metal soap.

Residual chlorine, odor turbidity, organic compounds, chlorinated hydrocarbons, etc. are removed. The pump 9 pressurizes the water pretreated by the prefilter 8 and supplies it to the reverse osmosis membrane filter 10. The water supplied from the pump 9 permeates the reverse osmosis membrane filter 10, so that the prefilter 8 Then, impurities such as dissolved substances such as calcium, magnesium, and silicon that have not been removed are almost completely removed to generate permeated water (removed water). At this time, concentrated water containing a high concentration of the dissolved substance or the like is separated and produced as a secondary. The permeated water and the concentrated water separated and generated by the reverse osmosis membrane filter 10 are supplied as treated water to the water discharger 2 via the downstream water supply channel 3, and the concentrated water is supplied to the bathroom 1. It is discharged outside. The reverse osmosis membrane device 7a generates pure water having a conductivity of 1 μS / cm or less as permeate.

To drive. As a result, water (pure water) from which impurities such as dissolved substances have been removed by the reverse osmosis membrane device 7 a is discharged into the bathroom 1 from the water outlet 5 a of the currant 5 or the shower nozzle 6 a of the shower device 6.

  The bathroom water reforming system of the present example described above can discharge water from which dissolved substances have been removed by the removing means 7 (reverse osmosis membrane device 7a) from the water discharge section 2 provided in the bathroom 1. Therefore, a person in the bathroom 1 can use the water to rinse the bathroom 1 and wash his body. And since the water discharged from the water discharge part 2 in the bathroom 1 removes dissolved substances such as calcium, magnesium, and silicon, it prevents the dirt and microorganisms from adhering in the bathroom 1. it can. Moreover, since the water discharged from the water discharge part 2 is a thing from which the mineral component was removed, generation | occurrence | production of metal soap can be suppressed and it can prevent that the cleaning power of soap falls by this. In addition, since the reverse osmosis membrane device 7a can also reduce the residual chlorine concentration contained in the water supplied from the water supply source, the water discharger 2 can discharge water with less irritation to the skin, and can be used for people with sensitive skin. It is valid.

  In this example, the removing means 7 is constituted by the reverse osmosis membrane device 7a. However, other removing means 7 conventionally used can be used as long as the dissolved substance can be removed to produce high purity water. May be.

  Next, another example of the water reforming system is shown in FIG. In the following explanation, the same number is given about the same composition as an example, and the duplicate explanation is omitted.

  The water reforming system of another example shown in FIG. 2 is treated water that is water from which dissolved substances have been removed by removing means 7, or non-treated water that is water from which dissolved substances have not been removed by removing means 7, or Of the mixed water obtained by mixing the treated water and the non-treated water, any one type of water can be selectively discharged from the water discharger 2, and the mixing ratio of the treated water and the non-treated water in the mixed water It is provided with a mixing ratio adjusting means for adjusting.

  The water supply path 3 includes a main flow path 14 that connects the water supply source and the water discharge unit 2, and a sub flow path 15 that is a bypass path of the main flow path 14. Only the reverse osmosis membrane device 7a is provided. In the main channel 14, downstream of the branch point 18 with the sub-channel 15 and upstream of the junction 19 with the sub-channel 15, and upstream of the reverse osmosis membrane device 7 a in the sub-channel 15. Are provided with valves 16 and 17 comprising electromagnetic valves having a flow rate adjusting function.

  The water reforming system of this example can selectively discharge any one of the treated water, non-treated water, or mixed water from the currant 5 or the shower device 6.

  That is, when the treated water is discharged from the water discharger 2, water is supplied from the water supply source to the water supply channel 3, the valve 16 is closed and the valve 17 is opened, and the pump 9 of the reverse osmosis membrane device 7a is driven. . As a result, the water supplied to the water supply channel 3 flows toward the sub-flow channel 15 and is processed by the reverse osmosis membrane device 7a as in the example, and then discharged from the water discharge unit 2 as treated water.

  Moreover, when discharging non-process water from the water discharge part 2, water is supplied to the water supply path 3 from a water supply source, and the valve 17 is closed and the valve 16 is opened. As a result, the water supplied to the water supply channel 3 does not flow to the side of the sub-flow channel 15 provided with the reverse osmosis membrane device 7a but flows through the main channel 14 and is not treated by the reverse osmosis membrane device 7a from the water discharge part 2. It is discharged as water.

  Moreover, when discharging mixed water from the water discharge part 2, water is supplied to the water supply path 3 from a water supply source, the valves 16 and 17 are opened together, and the pump 9 of the reverse osmosis membrane device 7a is driven. Moreover, the opening degree of each valve 16 and 17 at this time becomes an opening degree according to a mixture ratio set in advance by operation of an operation unit (not shown). As a result, the water supplied to the water supply channel 3 flows into the main flow channel 14 and the sub flow channel 15, and then passes through the sub flow channel 15 at the junction 19 to be treated with the treated water and the main flow processed by the reverse osmosis membrane device 7a. Untreated water that has not been treated after passing through the passage 14 joins, and the treated water and the untreated water are mixed at a ratio corresponding to the degree of opening of the valves 16 and 17. Then, the treated water and the non-treated water are discharged from the water discharge unit 2 as a mixed water mixed at a predetermined mixing ratio. That is, in this example, the mixing ratio adjusting means is constituted by the valves 16 and 17 having a flow rate adjusting function.

  As described above, the water reforming system of this example is a treated water that is water from which dissolved substances have been removed by the removing means 7, or non-treated water that is water from which dissolved substances have not been removed by the removing means 7, or Since any one kind of water can be selectively discharged from the water discharger 2 among the mixed water obtained by mixing the treated water and the non-treated water, water is necessary but water from which dissolved substances are removed is unnecessary. When the water from which the dissolved substance has been removed is necessary or when high purity water is not necessary, the untreated water or the mixed water can be discharged from the water discharger 2 and the load on the removing means 7 can be reduced. Moreover, when discharging mixed water, the mixing ratio of treated water and non-treated water can be adjusted to a desired mixing ratio, and mixed water having a necessary mixing ratio can be obtained.

  Next, another example of the water reforming system is shown in FIG. In the following description, the same components as those of the water reforming system of the other example shown in FIG.

  In this example, in addition to the currant 5 and the shower device 6, the water discharge unit 2 includes a spraying device 20 that sprays the water from which the dissolved substance has been removed by the removing means 7 into the bathroom 1. In addition, the upstream end of the branch path 22 is connected to the branch point 23 on the downstream side of the reverse osmosis membrane device 7 a in the sub-flow path 15, and the downstream side of the branch path 22 is connected to the spraying device 20. The branch point 23 is provided with a valve 24 composed of a three-way electromagnetic valve. By switching the valve 24, the water from which the dissolved substance has been removed by the reverse osmosis membrane device 7a is supplied to the spray device 20, and the spray device 2 has. It can be sprayed into the bathroom 1 from a large number of nozzles 20a.

  That is, when discharging treated water from the spraying device 20, water is supplied from the water supply source to the water supply channel 3, the valve 16 is closed and the valve 17 is opened, the valve 24 is switched to the spraying device 20 side, and the reverse osmosis membrane The pump 9 of the device 7a is driven. As a result, the water supplied to the water supply channel 3 flows to the sub-flow channel 15 side and is processed by the reverse osmosis membrane device 7a, and then discharged from the spraying device 20 through the branch channel 22 as treated water.

  Further, in order to discharge treated water from the currant 5 or the shower device 6, water is supplied from the water supply source to the water supply channel 3, the valve 16 is closed and the valve 17 is opened, and the valve 24 is switched to the main flow channel 14 side. The pump 9 of the osmotic membrane device 7a is driven. As a result, the water supplied to the water supply channel 3 flows to the sub-flow channel 15 side and is processed by the reverse osmosis membrane device 7a, and then discharged as treated water from the currant 5 and the shower device 6 through the main flow channel 14. .

  The water reforming system of this example can spray the water from which dissolved substances have been removed by the removing means 7 by the spraying device 20 into the bathroom 1, and can wash a wide area in the bathroom 1 using the sprayed water.

  In addition, although discharge of the treated water from the said spraying apparatus 20 may be performed by switching the valve 24 manually, you may make it discharge treated water from the spraying apparatus 20 automatically, for example after bathing. Here, as an example of the determination after bathing, for example, a human body detection sensor is provided in the bathroom 1, and after a person enters the bathroom 1 and the person is detected by the human body detection sensor, the person comes out of the bathroom 1 and is detected by the human body detection sensor. When it stops detecting a person, it is mentioned that it is after bathing.

  Next, another example of the water reforming system is shown in FIG. In the following description, the same components as those of the water reforming system of the other example shown in FIG.

  In the water reforming system of still another example shown in FIG. 4, a separate curan is provided in the bathroom 1 as a discharge unit 25 that discharges water containing dissolved substances removed by the removing means 7. The discharge unit 25 is connected to the reverse osmosis membrane filter 10 of the reverse osmosis membrane device 7 a through the concentrated water channel 26, and a drainage channel 28 is connected to the concentrated water channel 26. A valve 29 made of a three-way solenoid valve is provided at a branch point 27 of the concentrated water channel 26 with the drainage channel 28. By switching the valve 29, the concentrated water supplied from the reverse osmosis membrane device 7a is passed through the concentrated water channel 26. It can be discharged into the bathroom 1 from the discharge part 25.

  That is, in order to discharge concentrated water from the discharge unit 25 into the bathroom 1, when the treated water is discharged from the water discharge unit 2 described above, that is, water is supplied from the water supply source to the water supply path 3 and the valve 16 is closed. When both valves 17 are opened and the pump 9 of the reverse osmosis membrane device 7a is driven, the valve 29 is switched to the discharge unit 25 side. Thereby, the concentrated water separated and generated when the permeated water (removed water) is generated by the reverse osmosis membrane device 7 a is discharged from the discharge unit 25 into the bathroom 1 through the concentrated water flow channel 26. Further, in order to prevent the concentrated water from being discharged from the discharge section 25 when the treated water is discharged from the water discharge section 2, the valve 29 is switched to the drainage channel 28 side, and the concentrated water generated by the reverse osmosis membrane device 7a. Is drained to the outside of the bathroom 1 through the drainage channel 28.

  The water reforming system of this example can discharge water containing dissolved substances removed by the removing means 7, that is, concentrated water containing abundant minerals, from the discharge unit 25 into the bathroom 1. Available.

  In this example, the drainage channel 28 is branched from the concentrated water channel 26 and the valve 29 is switched so that the concentrated water can be discharged from the drainage channel 28. However, the drainage channel 28 and the valve 29 are not provided, and the water discharge unit Concentrated water may be discharged from the discharge unit 25 at all times when the treated water is discharged from 2. Also in this example, as in the example of FIG. 3, the upstream end of the branch path 22 is connected to the branch point 23 downstream of the reverse osmosis membrane device 7 a in the sub-flow path 15, and the downstream side of the branch path 22 is connected to the downstream end of the branch path 22.
