That's what you don't.

  A heating device 28 is provided inside the water softener, and includes a resin chamber 1, a regeneration chamber 2, an injection pump 21, a cleaning line 20, a cleaning line A 20a, a regeneration line 9, a regeneration line A 9a, and raw water. The entire interior of the equipment is heated so that the water inside each of the softening line 5, the soft water line 15 and the drainage line 11 is not frozen. When there is a risk of freezing, the control circuit in the heating device 28 operates to energize the heating device 28 to prevent water in the device from freezing.

  Next, the operation of the water softener having the above configuration will be described.

  First, in order to soften the raw water, the soft water valve 7 of the discharge cock 17 is opened, and then the raw water softening valve 6 of the raw water supply cock 16 is opened. Then, the raw water is softened at a flow rate of about 10 liters / minute. The resin enters the resin chamber 1 from below the resin chamber 1 through the line 5 and replaces calcium and magnesium with sodium while raising the ion exchange resin 13 upward. The substituted raw water is softened and the upper portion of the resin chamber 1 is replaced. From the discharge line 8 through the soft water line 15 and the soft water valve 7 of the discharge cock 17.

  At this time, the raw water softening valve 6 has a function of a pressure reducing valve so that the pressure of the raw water is changed to an appropriate pressure and sent to the resin chamber 1.

  In order to stop the release of soft water, the release of soft water stops if the soft water valve 7 or the raw water softening valve 6 is closed, but normally both the valves 6 and 7 are closed to stop the release of soft water.

  When the soft water discharged from the discharge line 8 is used for haircut or bathing, the water temperature is controlled by a temperature control device with a temperature controller to heat the water heater 26 at an appropriate temperature of about 40 ° C. Is to be obtained.

  At this time, the hot water thermostat 29 provided in the soft water line 15 ensures safety by preventing hot hot water that may cause burns from being released.

  In addition, when hot water such as a boiler provided outside is supplied to the raw water supply cock 16 to soften it and use it for washing hair or bathing, the hot water thermostat 30 prevents hot water from flowing in and damaging the equipment. To prevent the intrusion.

  Next, when the ion exchange resin 13 is regenerated, when the drain valve 12 is opened and then the regeneration valve 10 of the regeneration line 9 is opened, the regeneration is performed through the regeneration line 9 at a low pressure of about 1 liter / minute. Raw water flows into the interior from the upper part of the chamber 2, and the salt water in which the salt of the internal refreshing agent 14 is dissolved moves from the lower part of the regeneration chamber 2 to the resin chamber 1 through the regeneration line A9a, the injection pump 21, and the cleaning line A20a. Start.

  At this time, the regeneration valve 10 has the function of a pressure reducing valve, and changes the pressure of the raw water to an appropriate pressure and sends it to the resin chamber 1.

  The salt water entering the resin chamber 1 regenerates the ion exchange resin 13, passes through the drain line 11 from below the resin chamber 1, passes through the drain valve 12, and is discharged from the discharge line 8. At this time, by reversing the flow of water in the resin chamber 1 from the flow direction of the raw water at the time of soft water preparation, it is easy to remove impurities accumulated at the time of soft water preparation and improve the cleaning performance of the circulation system. ing.

  At this time, the regeneration rate of the ion exchange resin 13 is improved by reducing the pressure of the raw water for regeneration and slowly moving the water. This operation is completed in a time corresponding to the amount of the ion exchange resin 13.

  Next, a cleaning operation is performed in order to remove excess salt water adhering to the ion exchange resin 13 at the end of the regeneration operation and salt remaining in the drain line 11, the drain valve 12, the discharge line 8, and the like.

  In the cleaning operation, the regeneration valve 10 is closed, the cleaning valve 19 is opened, and raw water with a large flow rate of about 15 liters / minute is caused to flow into the resin chamber 1 through the injection pump 21, so that excess salt water or dust adhering to the ion exchange resin 13 is obtained. In addition, the drainage line 11, drainage valve 12, and discharge line 8 are also washed and discharged from the discharge line 8. And the time of this washing | cleaning operation | work is made to complete | finish at different time according to the structure of an apparatus.

  At this time, the jet pump 21 acts, and when passing through the jet pump 21, the raw water is accelerated by the nozzle 22 and decelerated by the diffuser 23. Therefore, the suction port 31 inserted between the two is decompressed by the ejector effect. Then, the regeneration chamber 2 connected to the suction port 31 through the regeneration line A9a has a negative pressure, the intake valve 18 sucks air by the negative pressure, and the salt water in the regeneration chamber 2 enters the resin chamber 1 over time. It is sent together with the raw water, and finally the salt water in the regeneration chamber 2 disappears and is filled with air. Thereafter, all the raw water supply cocks 16 are closed, and then all the discharge cocks 17 are also closed.

  Next, the refreshing agent 14 for regenerating the next ion exchange resin 13 is opened from the refreshing agent inlet 3 by opening the lid 4 of the regeneration chamber 2, and the lid 4 is closed to finish.

  As described above, the water heater 26 is provided in the resin chamber 1 and the temperature of the internal water is controlled so as to be constant within the range of 35 ° C. to 50 ° C., so that hot water having an appropriate temperature suitable for shampooing and bathing is obtained. Can be released.

  In addition, an injection pump 21 including a nozzle 22, a diffuser 23, and a suction port 31 is provided between the regeneration line 9 and the cleaning line 20, and the ejector effect at the time of cleaning salt water in the regeneration chamber 2 that is full during regeneration operation. Since the regeneration chamber 2 can be installed at a position lower than the resin chamber 1, the overall height of the device can be lowered, and the entire device can be made compact. Therefore, it can heat efficiently.

  In addition, the most upstream point for supplying raw water to the raw water softening line 5, the regeneration line 9, and the washing line 20 and the hot water thermostats 30 and 29 for preventing the passage of hot water of 60 ° C. or more are provided in each of the soft water lines 15. Can prevent the ingress of hot water that damages the water softener equipment, and by preventing the high temperature water from coming out of the soft water discharge line 8, it is safe and convenient to wash and bath. Can be provided.

  In addition, by providing the heating device 28 so that the water in the water softener and the water inside the device do not freeze, it is possible to prevent the operation from being lost due to freezing in winter.

  Furthermore, since the overall height of the device is low and the entire device is compact, the entire device can be efficiently heated by the heating device 28, so that the effect of preventing freezing is easily obtained.
