再生される。BEST MODE FOR CARRYING OUT THE INVENTION In the water softening section of the water softening device of the present invention, raw water is softened using a generally used cation exchange resin. The cation exchange resin removes calcium ion (Ca 2+ ) and magnesium ion (Mg 2+ ) in tap water. In the initial stage, in the matrix of the ion exchange resin, the anion (R—SO 3 −) is bound to the cation sodium ion (Na + ). When tap water is introduced into the cation exchange resin, ion exchange starts, Ca 2+ and Mg 2+ are adsorbed on the resin, and Na + is released instead. Therefore, the hardness component C
Water is softened by removing a 2+ and Mg 2+ . Also, since the exchange capacity of cation exchange resin is limited,
When the exchange capacity is lowered, it is regenerated, but it is generally regenerated by passing salt water (NaCl). NaCl
When water is passed, Ca 2+ and Mg 2+ become chlorine ions Cl
It is regenerated by binding with − and being discharged, while Na + is bound with R—SO 3 − to restore the initial state of the cation exchange resin.

うな使い勝手が得られる。An opening / closing valve is used to allow tap water to flow into the water softening portion of such a water softening device, and the opening / closing valve is housed in the same casing as the water softening portion.
The entire water softening device can be made compact. In addition, there is an on-off valve that opens and closes the tap water passage and also switches the passage to the shower or Karan.By connecting such an on-off valve and the water softening part, the water softening device as a whole can be used. However, it is possible to use it as if using a normal faucet.

It is required to have the ability to prevent. That is, in a water softener that is connected to a faucet that is connected to a water supply and uses a salt water to regenerate a cation exchange resin, it is necessary to use a means for preventing backflow on the upstream side of the water softener. The supply of water to generate salt water for regeneration can be performed by operating only the regeneration valve regardless of whether the on-off valve is open or closed by using some regeneration valve and connecting this regeneration valve directly to the tap water. To be able to
Usability is further improved.

が劣化したときの交換作業が容易になる。The amount of the cation exchange resin is determined according to the required amount of soft water and the hardness of raw water. For example, about 50 in the shower
When L soft water is required, the raw water hardness should be approximately 150 mg / L.
Then, about 200 mL of the cation exchange resin is required, but the cation exchange resin is determined according to the required amount of soft water targeted by the water softening device and the targeted raw water hardness. However, the hardness of water that has passed through the cation exchange resin is preferably 30 mg / L or less. When the hardness is 30 mg / L or less, the soap foams well, the cleaning power is improved, and the scale is less likely to adhere. The hardness of water described here is
It is shown by the content of calcium salt and magnesium salt in water. Further, if the water softening part is equipped with a cation exchange resin cartridge containing a cation exchange resin, and the cation exchange resin cartridge is structured so that it can be exchanged from the outside of the casing, the cation exchange resin will deteriorate. The replacement work becomes easy.

When the shower head 23 or the calan 24 discharges soft water, first, the temperature control handle 20 is operated to set the temperature, and then the switching handle. When 21 is operated to the shower side or the Karan side, the opening / closing part 16 is opened at the same time, and water and hot water flow from the water inlet pipe 13 and the hot water inlet pipe 14. Water and hot water flow into the mixing unit 15, and the mixing unit 15 automatically adjusts the mixing ratio of water and hot water so as to match the set temperature. The water mixed here passes through the supply pipe 3 through the opening / closing part 16 and flows into the cation exchange resin part 2. In the cation exchange resin part 2, the water that has passed through the cation exchange resin 1 is softened. Further, the internal pressure of the water softening unit 33 rises due to the inflow of water, and this pressure closes the check valve 10 of the salt water pipe 9 and the drain valve 11 of the discharge pipe 7. The water that has passed through the cation exchange resin 1 flows into the switching valve 19 through the soft water pipe 4, and is switched to the shower-side passage 17 or the calan-side passage 18 there, and is discharged to the selected side.

とした。In the case of regeneration, when the regeneration valve 8 is opened by some means (for example, switch operation), water flows from the regeneration pipe 6 into the salt tank section 5. Salt is stored in advance in the salt tank portion 5, and is dissolved by water from the regeneration pipe 6 to generate salt water. Since the water softening part 33 is in a state of being open to the atmosphere in a non-water-flowing state, salt water naturally flows down from the salt tank part 5 arranged at the upper part through the salt water pipe 9,
The cation exchange resin 1 is regenerated, and the drainage after regeneration is the drain valve 1.
1. The water is discharged to the outside of the water softening device 42 through the discharge pipe 7. In the embodiment, the drainage pipe 7 is connected so that the drainage after the regeneration is discharged to the floor of the washing floor of the bathroom through the drainage port 37 provided at the lower part of the bathroom counter 40 as shown in FIG.
