硬水を軟水化する軟水器に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water softener for softening hard water with an ion exchange resin.

下、従来の軟水器について説明する。2. Description of the Related Art In recent years, household water softeners that soften hard water with an ion exchange resin have become popular. Hereinafter, a conventional water softener will be described.

In FIG. 1, reference numeral 1 is a faucet, to which the water supply hose 2 of the water softener body 13 is connected. The water supply hose 2 is a water softener body 13
It is connected to an inlet 3 of a filtering cartridge 4 for filtering dirt and odor of raw water mounted therein with activated carbon, and an outlet 5 of the filtering cartridge 4 is connected to a filtered water outflow pipe 6.

続されている。Reference numeral 10 denotes a water softening container into which an ion exchange resin for softening hard water is injected, and an inflow pipe 8 is connected to an inflow port 9 thereof. Between the inflow pipe 8 and the filtered water outflow pipe 6, a salt case 7 for disposing salt when the ion exchange resin is regenerated is disposed, and the outlet 11 of the water softening container 10 is provided in the water softener body 13. It is connected to a discharge pipe 12 that discharges soft water to the outside.

り外部へ吐出される。When the faucet 1 is opened, raw water (hard water) passes through the water supply hose 2, and first flows into the filtration cartridge 4 to filter dirt and odor of the raw water, and then the filtered hard water is introduced into the inflow pipe. The water-softening container 10 into which the ion exchange resin has been injected passes through 8 to be softened and discharged from the discharge pipe 12 to the outside.

へ通水されることで再生が行われる。When water is passed through for a long period of time to soften the water, the capacity of the ion exchange resin decreases, so that it is necessary to regenerate the ion exchange resin. In this case, the case lid 14 is removed, and salt (regenerant) is put into the salt case 7 to pass water. Then, the salt that is the regenerant is dissolved, and the solution is passed through the ion exchange resin to regenerate.

という問題点があった。The ion exchange resin is regenerated as described above, but in the above conventional structure,
When soft water is used on a daily basis, it is not known at what point the softening capacity is reduced and regeneration must be performed, because the daily amount of soft water used and the usage time due to water pressure are unknown. Therefore, when the water is actually boiled in a kettle or the like, white floating substances are generated on the surface, or when white precipitates such as magnesium or calcium are generated on the bottom of the kettle or the like, the regeneration time has come. Therefore, there is a problem in that it is difficult to clearly determine when to carry out the rehabilitation.

ことを目的とする。[0008] Therefore, an object of the present invention is to provide a water softener in which it is possible to clearly determine when to regenerate an ion exchange resin.

In the middle of the filtered water outflow pipe 28, there are provided a pressure switch 22 that operates when passing water, and a constant flow valve 23 that operates in response to fluctuations in water pressure and passes a constant flow rate. The pressure switch 22 is connected to a circuit section 25 that operates on a dry battery (power source). The power switch is turned on and off by the operation of the pressure switch 22, and the water flow time is read by the circuit section 25. When the softening is performed for a certain period of time and the integrated time reaches the set time set by the circuit, the circuit unit 25 causes the LED 2

A case 24 of the pressure switch 22 is formed from a part of the water channel 8 and a diaphragm 29 that is operated by water pressure is fixed in the case 24. When the diaphragm 29 operates above, the switch 30 operates (ON state). The power source built in the circuit unit 25 is turned on and the circuit unit 25 operates. 31 is a lead wire. When water does not flow, the diaphragm 29 goes down, the switch 30 is turned off, and the power is turned off.
Then, the circuit section 25 is stopped. The circuit unit 25 reads and integrates the time from the ON state to the OFF state and accumulates the water passage time. Further, the constant flow valve 23 operates according to the fluctuation of the water pressure to ensure a constant flow rate. If the water flow rate during water softening changes significantly, the water softening efficiency fluctuates and constant water softening cannot be performed, and since the total water flow is determined by integrating the water flow time, there is a constant flow rate regardless of changes in water pressure. Need to pass water. Therefore, the combination of the pressure switch 22 and the constant flow valve 23 determines an accurate amount of softened water.

The execution of regeneration is informed by the used water flow rate of 0 to 140 liters. Therefore, when 10 liters / day of soft water is used, regeneration is performed once every 10 to 14 days.
