A voltage is applied between the plates 9 and 10, thereby generating alkaline ion water in the electrode chamber 7 a and discharging acidic ion water from the water discharge pipe 36 of the water discharge stand 2. After that, when the user closes the faucet 25 and stops the water, it is determined that the water is stopped based on the detection of the flow sensor 6, and the voltage application between the electrode plates 9 and 10 is stopped. The drainage solenoid valve 11 is set to open when water is passed in the acidic ionized water mode, and the alkaline ionized water generated in the electrode chamber 7b is discharged to the outside of the apparatus body 3 through the drainage pipe 13. The

  Further, when the water purification mode is selected by operating the water purification button 32c, no voltage is applied to the electrode plates 9, 10. Therefore, when the faucet 25 is opened and the raw water flows into the internal pipe 28, the purified water passing through the water purification unit 4 passes through the electrode chamber 7a of the electrolytic cell 7 without being subjected to electrolysis, and the water discharge stand. Water is discharged from the second water discharge pipe 36 as purified water.

Further, the main body side control unit 15 monitors the current flowing through the electrode plates 9 and 10 by the electrolysis current detection unit 22 in the alkaline ionized water mode and the acidic ionized water mode, so that no more than a certain current flows through the electrode plates 9 and 10. The application time of the voltage is controlled.

  Moreover, the main body side control part 15 reads the signal of the flow sensor 6, counts the amount of water flow, and when the total water flow amount reaches a certain amount, it displays on the display unit 18a that it is time to replace the water purification unit 4. Thus, the user can recognize that the water purification unit 4 has been clogged, and can prevent the electrolytic performance due to clogging of the water purification unit 4 from being deteriorated. In addition, clogging may proceed before the water flow rate reaches a certain amount due to the quality of the raw water, but this is monitored by monitoring the fluctuation of the signal from the flow sensor 6 to indicate that it is time to replace the water purification unit 4. It is prevented by displaying on 18a. In addition, when the water purification part 4 is replaced | exchanged, this can be detected now by the water purification part detection sensor 14, and when the new water purification part 4 is mounted | worn by this, the above-mentioned water flow count and water flow quantity Change monitoring is the initial state. Here, the counting of the water flow rate and the monitoring of the fluctuation of the water flow rate may be set to the initial state by operating the main body side operation unit 18b.

  Here, in the water treatment apparatus, as shown in FIG. 7, a plurality of transmission units 29 a and 29 b are provided as the transmission means 29 of the water discharge stand 2, and each transmission as the reception means 30 is provided in the apparatus body 3. There is provided only one receiving unit 30a for receiving the operation signal transmitted from the units 29a and 29b, and the operation signal generated by the operation of the operation unit 32 is transmitted from each of the transmission units 29a and 29b toward the ceiling 50. The operation signal is reflected by the ceiling 50 and received by the receiving unit 30a of the apparatus main body 3.

  Each of the transmission units 29a and 29b is composed of an optical transmission element composed of an LED that emits infrared rays. The transmitters 29a and 29b are mounted side by side on a control board 40a that constitutes the transmitter-side controller 40 built in the base 31, and the vertical pipe of the water discharge pipe 36 in front view of the base 31 in front view. It is arranged at symmetrical positions on both the left and right sides with respect to 33. Each of the transmission units 29a and 29b has a different optical axis direction that enables transmission at the maximum output. Specifically, each transmission unit 29a and 29b is moved outwardly in the left-right direction (that is, the other side) Inclined and mounted on the control board 40a so as to be inclined in the direction away from the transmission unit), thereby the transmission direction (that is, the direction of the optical axis) of each transmission unit 29a with respect to the vertical direction as shown in FIG. Is inclined in the left-right direction by an angle θa or an angle θb. In addition, transmission window portions 41a and 41b are provided at positions on the top surface of the base portion 31 on the tip side of the transmission portions 29a and 29b, and the operation signals transmitted from the transmission portions 29a and 29b are opposed to each other. The image is transmitted obliquely above the apparatus body 3 through the windows 41a and 41b.

  The receiving unit 30a is constituted by a receiving element capable of receiving the operation signal transmitted from the transmitting units 29a and 29b, and is built in the upper end portion below the upper surface portion of the apparatus body 3 as shown in FIG. 6 (b). It is mounted on a control board 15 a constituting the main body side control unit 15. The control board 15a is inclined at an angle θ with respect to the horizontal direction so that the upper surface on which the receiving unit 30a is mounted faces upward and obliquely forward, so that the receiving unit 30a is orthogonal to the control board 15a, that is, the front It is in a state in which it is most likely to receive an operation signal from obliquely above. Further, a transmission window 44 is provided at a position facing the receiving unit 30a on the upper surface of the apparatus body 3, and an operation signal transmitted from each of the transmission units 29a and 29b and reflected from the ceiling 50 is transmitted through the transmission window 44. It passes through and reaches the receiving unit 30a.

  As described above, the water treatment apparatus of this example is composed of the apparatus main body 3 and the separate water discharge stand 2, so the water discharge stand 2 that discharges treated water is placed at a desired position away from the apparatus main body 3. The apparatus main body 3 can be remotely operated by the operation unit 32 provided in the water discharge stand 2 and is easy to use. In particular, since a plurality of transmission units 29a and 29b are provided in the water discharge stand 2, communication between small items, the water discharge unit 21 (water discharge pipe 36) and the like is inhibited in the transmission direction of any one of the plurality of transmission units 29a and 29b. Even if an obstacle to be positioned is located, communication with the receiving unit 30a can be ensured by another transmission unit, and the apparatus body 3 and the water discharge stand 2 constituting the water treatment apparatus can be installed at any position without considering the obstacle. can do.

  In this example, the operation signal from the operation unit 32 is transmitted from the transmission units 29a and 29b toward the ceiling 50, and the operation signal is reflected by the ceiling 50 and received by the reception unit 30a of the apparatus main body 3. Even if an obstacle such as a small object is placed on the installation surface such as the sink 24 or the sink 24 on which the water discharge stand 2 is installed, the operation signal can be received by the receiving unit 30a by avoiding the obstacle. Communication can be ensured more reliably.

  Further, in this example, the water discharge portion 21 is provided with a vertical pipe portion 33 raised from the base portion 31 and a water discharge port portion 35 that extends in the horizontal direction from the upper end portion of the vertical pipe portion 33 and discharges treated water at the tip portion. It comprises a water discharge pipe 36 comprising a horizontal pipe part 34, and the horizontal pipe part 34 of the water discharge pipe 36 is rotatable around the vertical axis, and in addition, it can be seen from the positions of the transmission window parts 41a and 41b in FIG. As described above, a plurality of transmission units 29a and 29b are provided in the rotation direction of the horizontal tube portion 34 with a space in plan view, so that one of the plurality of transmission units 29a and 29b rotates in the transmission direction of the transmission unit. Even if the horizontal pipe part 34 of the water discharge pipe 36 that has become free is located and communication is hindered, communication with the receiving part 30a can be ensured by another transmitting part.

  Further, in this example, as shown in FIG. 7, the transmission direction of the operation signal from each transmission unit 29a, 29b is made different, and the transmission direction of each transmission unit 29a, 29b is inclined in the opposite direction. An operation signal can be transmitted to the device, and the transmission and reception range can be expanded. In this case, since the transmission direction of each of the transmission units 29a and 29b is inclined with respect to the vertical direction, even if the apparatus main body 3 is installed at a position relatively away from the water discharge stand 2 as shown in FIG. As in the comparative example shown in FIG. 10, an operation signal having a stronger output can be received by the receiving unit 30a compared to the case where the transmission direction is the vertical direction, and the reception accuracy is improved. Further, in this example, as shown in FIG. 6 (b), the control board 15a on which the receiving unit 30a is mounted is tilted, so that the receiving unit 30a is most likely to receive an operation signal from diagonally forward. As shown in FIG. 8, even if the water discharge stand 2 is installed at a relatively distant position in front of the apparatus main body 3, a strong output operation signal can be received by the receiving unit 30a, and the receiving accuracy is improved.

  Here, in FIG. 11 (a) and FIG. 11 (b), among the operation signals received by the receiving unit 30a of this example, the operation signal from one transmission unit is on the upper stage, and the operation signal from the other transmission unit is on the lower stage. The shown time chart is shown. As a comparative example, in FIG. 12A and FIG. 12B, among the operation signals received by the receiving unit 30a, the operation signal from one transmission unit is on the upper stage, and the operation signal from the other transmission unit is on the lower stage. The shown time chart is shown. Here, FIG. 11A and FIG. 12A are cases where the operation signal from each of the transmission units 29a and 29b is normally received by the reception unit 30a, and FIG. 11B and FIG. This is a case where the operation signal from one of the transmission units cannot be normally received by the reception unit 30a. 11 (a), 11 (b), 12 (a), and 12 (b), the operation signal first received by the receiving unit 30a in FIGS. 11 (a) and 12 (a) is described as frame 1. The operation signals received after the second are described as frame 2, frame 3,.

  The operation signals transmitted from the transmission units 29a and 29b are composed of frame signals obtained by framing the reader unit and the data unit as one frame at a predetermined time t2 as shown in FIG. In the state where the operation buttons 32a to 32c constituting the operation unit 32 provided in the water discharge stand 2 are pushed, the transmission side control unit 40 corresponds to the operated operation button 32a. The same operation signal at the output time t2 is repeatedly transmitted at a predetermined transmission time interval t1, and the operation signals transmitted from different transmission units 29a and 29b are transmitted with a phase shift so as not to overlap. That is, in this example, since two transmission units are provided, operation signals are transmitted alternately from the respective transmission units 29a and 29b.

  After receiving the first operation signal indicated by frame 1 in FIG. 11 by the receiving unit 30a, the main body side control unit 15 of the apparatus main body 3 receives a predetermined time T ′ (here, the predetermined time T ′ from the end of the first operation signal). Is counted until t1: <transmission time interval, t2: output time of the operation signal) satisfying the relationship of t1 <T ′ <t1 + t2, and the second operation signal is not received at the time of counting. The operation signal received first is canceled. In addition, the second operation signal (the operation signal indicated by frame 2 in FIG. 11A and the operation signal indicated by frame 3 in FIG. 11B) that is the same as the first operation signal was received at the first count. In this case, the operation signal is determined as an operation signal for switching the operation mode of the apparatus body 3, and hereinafter, a predetermined time T (where the predetermined time T is the predetermined time T ′ described above) from the end of the second operation signal. And the time t1 <T <t1 + t2 is satisfied) until the predetermined time T elapses from the end of the second operation signal received at the time of counting. The control is continued until no operation signal is received at the second and subsequent counts excluding the first count, and no operation signal is received at the second and subsequent counts. The operation signal received before the count (i.e. the determined operation signal) on the basis of the switch the operating mode of the device body 3 when.

  As described above, in the water treatment apparatus of this example, when the operation buttons 32a to 32c constituting the operation unit 32 are pressed, the transmission units 29a and 29b transmit the same operation signal of the output time t2 as a predetermined transmission. The signal is transmitted repeatedly at the time interval t1 and transmitted with a phase shifted so that operation signals transmitted from different transmission units do not overlap, and the operation signal (second operation signal in this example) is received by the reception unit 30a. Is received until the predetermined time T elapses from the end of the operation signal, and when the operation signal is received at the time of counting, until the predetermined time T elapses from the end of the operation signal received at the time of counting A new count is performed, and thereafter, the control is continued until no operation signal is received at the time of counting. Since it controls the operation of the apparatus body 3 to switch the operation mode based on the received operation signal, when the operation button 32a to 32c is released, the last received operation signal is terminated. When a predetermined time T elapses, it is possible to detect the release of the pressing operation of the operation buttons 32a to 32c, and thereby it is possible to execute an operation of quickly switching the operation mode of the apparatus body 3. Particularly in this case, as shown in FIG. 11B, the water discharge stand 2 is installed at a position away from the apparatus main body 3 in the left-right direction, or an obstacle is positioned in the transmission direction of one of the transmission units. Even if the operation signal received by the receiving unit 30a has a tooth missing state, the operation of the apparatus main body 3 switches the operation mode between the operation signal received by the receiving unit 30a and the next received operation signal. Can be prevented. That is, for example, as shown in FIG. 12A, when the predetermined time T is set to Ta in FIG. 12, assuming that the operation signal from each of the transmission units 29a and 29b can be reliably received by the receiving unit 30a, FIG. When a tooth missing state occurs in the operation signal received by the receiving unit 30a as shown in (b), the operation signal is determined each time when the time Ta elapses from the end of each operation signal received by the receiving unit 30a. In this example, this can be prevented by the above control.

  In this example, the predetermined time T is counted when the second operation signal is received, and is controlled as described below. However, when the first operation signal is received, from the end of the first operation signal. The predetermined time T may be counted, or the predetermined time T may be counted when the third and subsequent operation signals are received.

  Next, another example of the water treatment apparatus different from the above example will be described. In the following explanation, the same number is given about the same composition as the water treatment apparatus of the above-mentioned example, and the duplicate explanation is omitted.

  As shown in FIGS. 13 and 14, the water treatment apparatus of the present example does not include the water discharge stand 2, and is provided with a faucet 25 that supplies raw water and a switching unit 47 that is provided with a raw water discharge port (not shown).

  The basic configuration of the apparatus main body 3 is the same as the apparatus main body 3 of the water treatment apparatus of the above example. Instead of the communication pipe 20 of the water treatment apparatus of the example, a discharge pipe 45a constituting the treated water discharge portion 45 is replaced with an electrolytic cell. 7 in that the water used in the electrode chamber 7a can be discharged from the discharge port portion 46 provided at the tip of the discharge pipe 45a.

  The switching unit 47 is connected to the rear part of the upper surface portion with the raw water outlet 27 of the faucet 25, and discharges the raw water supplied from the faucet 25 from its own raw water outlet or is supplied from the faucet 25. A switching lever 48 is provided as a switching means for switching whether raw water is supplied to the apparatus main body 3 through the water supply pipe 23. The switching lever 48 includes an operation unit 32 for remotely operating the apparatus main body 3 provided in the water discharge stand 2 in the above example (that is, although not shown, an alkaline ion water button 32a, an acidic ion water button 32b, and a water purification button 32c). ), A transmission means 29 for wirelessly transmitting the operation signal 32 to the reception means 30 provided in the apparatus body 3 when the operation section 32 is operated, a transmission side control section 40, and a battery 52 as a power source. is there. Here, the operation unit 32 is provided on the upper surface of the switching unit 47, and the transmission unit 29, the transmission side control unit 40, and the battery 52 are built in the switching unit 47.

In particular, since the switching unit 47 is provided with a plurality of transmission units 29a and 29b, obstacles that obstruct communication such as small articles and levers of the faucet 25 in the transmission direction of any one of the plurality of transmission units 29a and 29b. Even if it is located, communication with the receiving part 30a can be ensured by another transmitting part, and the apparatus main body 3 constituting the water treatment apparatus can be installed at a free position without considering obstacles.
