The switch case 80 is fixed to the upper portion of the cylindrical body 100 with a screw 102 or the like.

  The specific configuration according to Example 1 of the present invention will be described below. The water conditioner 1 according to the present invention is a device for taking out the ionic water generated by introducing the tap water that has passed through the water purifier 2 having the water purification filter 2 </ b> A into the electrolytic cell 3 from the discharge pipe 4. The electrically connected electrical unit 5 and the electrolytic cell 3 are housed in one or separate boxes 6 and are adjacent to each other to form an integrated water conditioning unit 7. Power is supplied to the electrical component 5 from the power supply line 45.

  Reference numeral 12 denotes a rotary knob for turning a stop cock that opens and closes a water supply pipe for city water, and the water tap is opened by the rotary knob 12 so that the water purifier is removed from the pipe 13 constituting the water supply water channel. 2 is introduced. The water supply channel of the pipe 13 is opened and closed by the electromagnetic valve 14 based on the operation of the switch device 8 as described later. This water purifier 2 is equipped with a water purification filter 2A for filtering residual chlorine, trihalomethane, pesticides, turbidity, odor of lime, etc. by sequentially passing through a purification layer of granular activated carbon and a hollow fiber membrane after filtering dust through a non-woven filter. Yes. This water purification filter 2A is a cartridge type in which a nonwoven fabric filter, a granular activated carbon purification layer and a hollow fiber membrane are housed, and has a cartridge configuration on the market, and is attached to and removed from the main body of the water purifier 2 for replacement. It is a configuration that can be freely attached.

  The discharge pipe 4 is composed of two pipes 4A and 4B. The pipe 4A includes a pipe 4A1 extending upward from the electrolytic cell 3, a flexible pipe 4A2 disposed in the switch case 80, and a synthetic resin molded body attached in the switch case 80 so as to connect the pipe 4A1 and the pipe 4A2. The pipe 4A3. A main pipe 15 is connected to the upper end of the pipe 4A2 through a connection pipe 4A4 as will be described later.

  The pipe 4B includes a pipe 4B1 extending upward from the electrolytic cell 3, a flexible pipe 4B2 disposed in the switch case 80, and a synthetic resin attached in the switch case 80 so as to connect the pipe 4B1 and the pipe 4B2. It consists of a molded pipe 4B3. A sub pipe 16 is connected to the upper end of the pipe 4B2 through a connection pipe 4B4 as described later.

  The tap water introduced into the water purifier 2 becomes purified water through the water purification filter 2A, and this purified water is introduced into the electrolytic cell 3 through the pipe 10 after passing through calcium in a calcium addition tube 2B described later. The electrolytic cell 3 has a known function of electrolyzing tap water with positive and negative electrodes to generate alkaline ionized water and acidic water (also referred to as acidic ionized water). When one electrode is positive and the other electrode is negative (this is referred to as “positive conduction”), one electrode is negative so that the polarity of the electrode is reversed. In addition, the switch device 8 can select whether the other electrode is positively energized (hereinafter referred to as “reverse energization”) or not.

  The switch device 8 includes switches 8A, 8B, 8C, and 8D. The switch 8A selects three types of water, that is, strong alkaline ionized water, weak alkaline ionized water, and purified water for each ON. is there. The three selection states are displayed by lighting of the indicator lamps 17A, 17B, and 17C that are sequentially switched on each time the switch 8A is turned on. The switch 8C is a switch for selecting supply of acidic water. When the switch 8C is turned on, the indicator lamp 18 is turned on, and when it is turned on again, the indicator lamp 18 is turned off. The switch 8B is a water supply ON-OFF switch that starts and stops the supply of strong alkaline ionized water, weakly alkaline ionized water, purified water, or acidic water with the switch 8A or the switch 8C turned on.

  The switch 8D is used when the water filter of the water purifier 2 is replaced. The switch 8D is turned on, the indicator light 19 is lit to indicate that the water filter is being replaced, and the switch 8D is switched again after the water filter is replaced. By turning on, it can be confirmed that the indicator lamp 19 is extinguished and the normal state is restored.

  The positive energization can be achieved by turning on the water supply ON-OFF switch 8B in a state where alkali ion water is selected by turning on the switch 8A of the switch device 8. The switch 8A selects, for example, strong alkaline ionized water that turns on the indicator lamp 17A, and turns on the water supply ON-OFF switch 8B, thereby energizing the electrode of the electrolytic cell 3 and opening the electromagnetic valve 14 to open the water supply system. A passage through which water passes from the pipe 13 through the water purifier 2 and is introduced into the electrolytic cell 3 is formed. Strong alkaline ionized water generated in the electrolytic cell 3 is taken out from the main pipe 15 through the discharge pipe 4A. Energization of the electrode and the electromagnetic valve 14 is held by a self-holding relay (not shown) which is one of the electrical components 5.

  Since acidic water is also generated by this positive energization, this acidic water is taken out from the sub-pipe 16 through the discharge pipe 4B. In this case, since the positive energization is mainly taken out of strong alkaline ionized water, the sub-pipe 16 Acidic water taken out from the water may be considered as water discharged as sewage. The stop of the positive energization can be achieved by turning on the water supply ON-OFF switch 8B again to release the self-holding of the relay.

  The supply of weak alkaline ionized water can be similarly achieved by turning on the water supply ON-OFF switch 8B with the indicator lamp 17B lit by the switch 8A.

  The reverse energization can be achieved by turning on the water supply ON-OFF switch 8B in a state where acidic water is selected by the switch 8C of the switch device 8. When the switch 8C is turned ON and the water supply ON-OFF switch 8B is turned ON, the electrode of the electrolytic cell 3 is energized and the electromagnetic valve 14 is opened. After the tap water passes through the water purifier 2 from the pipe 13, the purified water supply is performed. A passage through which purified water is introduced into the electrolytic cell 3 through the pipe 10 is formed, and the acidic water generated in the electrolytic cell 3 is taken out from the main pipe 15 through the discharge pipe 4A. Energization of the electrolytic cell 3 and the electromagnetic valve 14 is held by a self-holding relay (not shown) which is one of the electrical components 5.

  Since the alkaline ionized water is also generated by the reverse energization, the alkaline ionized water is extracted from the sub-pipe 16 through the discharge pipe 4B. Since the reverse energization is mainly the extraction of the acidic water, the alkaline ionized water is extracted from the sub-pipe 16. The alkaline ionized water that is taken out may be considered as water that is discharged as surplus water. This stop of reverse energization can be achieved by turning on the water supply ON-OFF switch 8B again to release the self-holding of the relay.

  The removal of the purified water is achieved by selecting the state in which the indicator lamp 17C is lit by the switch 8A and turning on the water supply ON-OFF switch 8B. As a result, the energization circuit to the electrolytic cell 3 is cut off, the solenoid valve 14 is opened by energization, and a passage through which the tap water passes from the pipe 13 through the water purifier 2 to the electrolytic cell 3 is formed. However, since the electrode of the electrolytic cell 3 is not energized, the tap water is taken out from the main pipe 15 through the discharge pipe 4 </ b> A as it is after passing through the water purifier 2. Energization of the solenoid valve 14 is held by a self-holding relay (not shown) which is one of the electrical components 5.

  In this case, since the same purified water is taken out from the sub pipe 16 through the discharge pipe 4B, both the purified water taken out from the sub pipe 16 and the main pipe 15 can be received in a container such as a cup. This stop of the water removal can be achieved by turning on the water supply ON-OFF switch 8B again to release the self-holding of the relay.

  The two discharge pipes 4A and 4B are connected to the connection pipes 4A4 and 4B4 at the upper ends of the pipes 4A2 and 4B2 so that the main pipe 15 and the sub pipe 16 can be rotated by connection rings 20 and 21, respectively. The connection rings 20 and 21 are arranged on the upper surface of the control box 80 of the switch device 8, and the main pipe 15 and the sub pipe 16 can be pivoted left and right in this portion in a watertight state. For this reason, the main pipe 15 and the sub pipe 16 can be attached and exchanged by removing the connection rings 20 and 21. With this configuration, the main pipe 15 and the sub-pipe 16 are overlapped in the front-rear direction when viewed from the front, and can be in any state facing left or right by turning.

  The switch device 8 is attached to a faucet case 80 that holds and covers the discharge pipes 4A and 4B. The faucet case 80 has a waterproof structure made of a synthetic resin for electrical insulation and waterproofing with respect to the switch device 8, and the switch touch surface on the front surface is covered with a flexible synthetic resin film in a watertight state, and a switch is provided inside. And mounting members, lead wires, and the like associated therewith are housed.

  Reference numeral 22 denotes a general mixing plug, in which tap water is supplied through a tap water supply pipe 25, hot water is supplied from a hot water supply pipe 24, and the tap water, hot water, and mixed water of the tap water and hot water can be selectively taken out.
