Description

  The present invention relates to an electrolyzed water generating device that electrolyzes water supplied from a water supply channel to generate alkaline ionized water and acidic ionized water, and a sink equipped with the same.

  Conventionally known electrolyzed water generators are an electrolyzer that electrolyzes raw water such as tap water and well water supplied from a water supply channel to produce alkali ion water and acidic ion water, and both ion water in the electrolyzer. Of these, a discharge path for discharging one and a discharge path for discharging the other are provided.

  However, when the supply of water from the water supply path to the electrolysis tank is stopped, the electrolyzed water generating apparatus has a problem that water stays in the electrolysis tank, the discharge path, and the discharge path, and various germs propagate.

  For example, in the electrolyzed water generating apparatus shown in Patent Document 1, a drain pump is provided in the discharge channel, and the drain pump is set to a predetermined output that is determined in advance when the supply of water from the water supply channel to the electrolytic cell is stopped. It is possible to discharge the water staying in the electrolytic cell, the discharge path and the discharge path by driving the above, and in this case, the problem of propagation of the above-mentioned germs can be solved.

By the way, the electrolyzed water generating device is used, for example, by placing a main body with an electrolytic cell inside the sink, and piping and discharging the discharge path and the discharge path to the sink provided on the upper surface of the sink. In this case, the installation height of the main body with the drainage pump and the height position of the uppermost portion of the discharge path are not constant depending on the size of the sink. Therefore, in the electrolyzed water generating device shown in Patent Document 1, the height of the water drained by the drainage pump is not determined at the time of drainage, and the accumulated water is discharged by the drainage pump according to the change in the pumping height. The time required for the operation changes greatly, which gives distrust to the worker. In addition, for example, it may be set so that the operation is stopped by a timer or the like after a predetermined time after driving the drainage pump, but in this case, when the pumping height is small, the drainage pump is operated idly without stagnant water. There is a problem in safety, and when the pumping height is large, there is a problem that the accumulated water cannot be completely discharged.

Means are provided.

  In this way, the drain pump 14 is operated at a value corresponding to the detection result detected by the pumping height detecting means, so that the height (pumping height) at which the water drained by the drain pump 14 is pumped is changed.

  Further, as the pumping height detection means, a pump load detection means for detecting the load of the drainage pump 14, and the drainage pump 14 is driven when the supply of water from the water supply path 9 to the electrolytic cell 13 is stopped. It is also preferable to provide a control means for detecting the load of the drainage pump 14 at the time by the pump load detection means and calculating the pumping height based on the detection result. In this case, the pumping height can be calculated based on the load of the drainage pump 14 during driving.

  It is also preferable to provide input means for manually inputting the pumping height as the pumping height detection means. In this case, the input pumping height can be used as the pumping height that determines the output of the drainage pump 14.

  Also, a pump load detecting means for detecting the load of the drain pump 14 is provided, and a control means for stopping the pump when the load of the drain pump 14 detected by the pump load detecting means after the drain pump 14 is driven is below a predetermined value is provided.

  In the electrolyzed water generating apparatus of the present invention, even if the height at which the water drained by the drain pump is pumped up, the time required for discharging the stagnant water can be made substantially constant. A timer can be set so that the drainage pump stops when drainage is completed, and in this case, the drainage pump can be prevented from idling when the pumping height is small.

The drain pump 14 includes a motor (not shown) whose output is variable, and the motor of the drain pump 14 is electrically connected to the controller 12. The output (electric power) of the motor of the drainage pump 14 can be changed by the control unit 12 in three stages of high, standard, and low. Further, the main body 10 is provided with a motor load means comprising the control unit 12 for detecting the motor load such as the voltage of the drain pump 14 and the motor speed as a pump load detecting means for detecting the load of the drain pump 14. Provided. Further, an opening / closing valve 27 (see FIG. 2) made of an electromagnetic valve is provided downstream of the drainage pump 14 in the discharge passage 25 (specifically, inside an operation unit 26 described later), and the opening / closing valve 27 is normally closed. Yes. The pump load detection means is not limited to the motor load detection means, and may be constituted by means for detecting the water pressure on the output side of the pump, for example.

  And in the electrolyzed water generating apparatus 1 of this embodiment, the alkaline ion water production | generation mode which discharges alkaline ion water from the discharge path 24, the acidic ion water production | generation mode which discharges acidic ion water from the discharge path 24, discharge The operation mode is provided by operating a mode selection button (not shown) of the operation unit 26 provided with a display unit provided on the upper surface of the sink 2. Can be selected from an alkali ion water production mode, an acid ion water production mode, and a water purification mode. The operation unit 26 is provided with a pH value setting button (not shown), and the voltage and current applied between the electrodes 19a and 19b from the control unit 12 are changed by operating the pH value setting button. The pH value of the ionic water during operation in the alkaline ionic water production mode or acidic ionic water production mode can be changed.

  When the operation unit 26 is operated and the operation in the alkaline ion water generation mode or the acidic ion water generation mode is started, the branch valve 11 is switched so that the water in the water supply pipe 7 flows to the main body 10 side. The on-off valve 27 is opened, and power is supplied between the electrodes 19 a and 19 b of the electrolytic cell 13. Thus, impurities such as residual chlorine, trihalomethane, mold odor, and general bacteria are removed from the water supplied from the water supply pipe 7 to the water supply channel 9 via the branch point A by the water purification unit 15, and the purified water is supplied to the flow sensor. After passing through 21, branching point B branches to both branch paths 9a and 9b. The water that has flowed into the branch path 9a is processed into water that is easily electrolyzed by dissolving calcium ions such as calcium glycerophosphate and calcium lactate in the calcium supply section 16, and this water flows into the chamber 13a of the electrolytic cell 13, and The water that has flowed into the branch path 9b flows into the chamber 13b of the electrolytic cell 13 as it is. In the electrolytic cell 13, ion water generated in the selected alkaline ion water generation mode or acidic ion water generation mode and between the electrodes 19a and 19b under electrolysis conditions according to the pH value set by the pH value setting button. Predetermined power is supplied, so that during operation in the alkaline ionized water generation mode, electrolysis is performed with the chamber 13a of the electrolytic cell 13 as the cathode chamber and the chamber 13b as the anode chamber to generate ionic water. As a result, alkaline ionized water is discharged from the discharge port 24 a of the discharge path 24, and at the same time, acidic ion water is discharged from the discharge port 25 b of the discharge path 25. During operation in the acidic ion water generation mode, electrolysis is performed using the chamber 13b of the electrolytic cell 13 as the anode chamber and the chamber 13a as the cathode chamber to generate ionic water. Acidic ion water is discharged from 24a, and simultaneously, alkali ion water is discharged from the discharge port 25b of the discharge path 25.

  When the operation unit 26 is operated and the operation in the purified water mode is started, the branch valve 11 is switched so that the water in the water supply pipe 7 flows to the main body 10 side, and at the same time the on-off valve 27 is closed. Become. In the water purification mode, power is not supplied to the electrodes 19a and 19b of the electrolytic cell 13. Thereby, the water introduced into the water supply channel 9 from the water supply pipe 7 via the branch point A is purified by the water purification unit 15, and the purified water passes through the flow sensor 21, the branch channel 9 a, the electrolytic cell 13, and the discharge channel 24. Then, it discharges from the discharge outlet 24a of this discharge path 24. It is assumed that the drainage pump 14 is not operated during operation in each mode of the alkaline ionized water generation mode, acidic ionized water generation mode, and purified water mode.

  When the operation unit 26 is operated during operation in each of the alkaline ion water generation mode, acidic ion water generation mode, and purified water mode, the control unit 12 switches the branch valve 11. It switches so that the water of the water supply pipe 7 may flow to the faucet 8 side. When the operation in each mode is stopped by switching the branch valve 11 in this way, the amount of water flowing to the main body 10 side decreases, and the amount of water per unit time flowing through the water supply passage 9 detected by the flow sensor 21. Falls below a certain amount, whereby the control unit 12 determines that the water is stopped, ends the supply of power between the electrodes 19a and 19b of the electrolytic cell 13, and starts the following drainage mode.

  In the drainage mode, first, the on-off valve 27 is opened, and at the same time, the drainage pump 14 is driven with the motor output set to the standard. At the same time, the load of the drainage pump 14 at the time of driving with this output as a standard is automatically detected by the pump load detecting means, and the height from the main body 10 to the uppermost portion 25b of the discharge passage 25 from the detected load of the drainage pump 14 (that is, drainage). The height at which the water discharged by the pump 14 is pumped up is calculated. That is, in this example, the pump load detection means and the control unit 12 constitute a pumping height detection means for detecting the height at which drained water is pumped by the drainage pump 14 (hereinafter referred to as pumping height). Yes. The control unit 12 sets the output (that is, the lift) of the motor of the drain pump 14 to a value suitable for the pumping height, and drives the drain pump 14 with this set output hereinafter. That is, when the pumping height detected by the pumping height detecting means is large, the output of the drainage pump 14 is increased, and when the pumping height is small, the output of the drainage pump 14 is decreased. More specifically, a threshold value in two stages, upper and lower, is set, and when the detected pumping height is equal to or higher than the upper threshold value, the output of the drainage pump 14 is set to high, and is less than the upper threshold value and larger than the lower threshold value. In this case, the output of the drainage pump 14 is set to the standard, and when it is below the lower threshold, the output of the drainage pump 14 is set to low. By operating the drainage pump 14 in this way, the accumulated water in the discharge path 24, the electrolytic bath 13, and the discharge path 25 is pumped up and discharged into the sink 4 from the discharge port of the discharge path 25. The operation of the drainage pump 14 is stopped when a certain time has elapsed from the time when the output of the drainage pump 14 is pumped by a timer and set to a value corresponding to the height, and at the same time the on-off valve 27 is closed, and the drainage mode Ends.

  Here, the drainage pump 14 is operated at a value corresponding to the detection result detected by the pumping height detection means, so that the installation height in the sink 2 of the main body 10 and the height position of the uppermost portion 25b of the discharge passage 25 are set. Even if the pumping height is changed due to the change, the time for discharging all the accumulated water can be made substantially constant. Further, since the time required for discharging the staying water can be made constant in this way, the timer can be set so that the drainage pump 14 stops just when the staying water drainage is completed. When it is small, it is possible to prevent the drainage pump 14 from being idling, and it is possible to prevent a situation in which the accumulated water cannot be completely discharged when the pumping height is large.

  The output of the drain pump 14 at the time of drainage is set only at the first drain after the main body 10 is installed, and the drain pump 14 is operated at the output value set at the first time at the second and subsequent drains. Alternatively, the output of the drainage pump 14 may be set as described above for each drainage. In the latter case, the position and orientation of the discharge port 24a of the discharge channel 24 and the discharge port 25b of the discharge channel 25 can be changed as described above, so that the uppermost portion 24b and the discharge channel of the discharge channel 24 can be changed even after installation. This is particularly effective when the height position of the top 25 of the 25 is changed. The output of the drainage pump 14 can be changed in three stages according to the pumping height, but it may be changed in two stages or four or more stages, that is, the output of the drainage pump 14 can be changed in several stages according to the pumping height. If possible.

  Further, in this example, the operation of the drainage pump 14 is stopped when a certain time has elapsed from the time when the output of the drainage pump 14 is pumped by a timer and set to a value corresponding to the height. The drainage pump 14 may be stopped after a certain time from the start.

  Further, the operation of the drain pump 14 is stopped when a predetermined time set in advance by a timer elapses, but the load of the drain pump 14 detected by the pump load detecting means until the predetermined time elapses as shown in FIG. The control unit 12 may control the drain pump 14 to stop when the value is lower than the value, and the drain operation of the drain pump 14 can be reliably prevented.

  Further, the load of the drain pump 14 detected by the pump load detecting means after the drain pump 14 is driven without using the timer (specifically, after the drain pump 14 is operated with the output set according to the pumping height) is predetermined. The control unit 12 may control the drain pump 14 to stop when the value is equal to or less than the value (a value that is about the load when the drain pump 14 is idling). By controlling in this way, the operation of the drain pump 14 can be stopped according to the load of the drain pump 14, the idling operation of the drain pump 14 can be reliably prevented, and the accumulated water can be reliably discharged.

  Next, an embodiment different from the above will be described below. In this embodiment, there is a feature in that an input means for manually inputting the pumping height is provided as the pumping height detection means, and the same number is assigned to the same configuration as the above embodiment, A duplicate description is omitted.

  In the present embodiment, a main body position setting button is provided on the operation unit 26 as an input means for manually inputting the pumping height, and an operator or the like can use the main body position setting fixed button from the main body 10 to the uppermost portion 25b of the discharge path 25. The pumping height can be set by inputting the height up to. Then, the control unit 12 sets the output of the motor of the drainage pump 14 to a value suitable for the pumping height set by the main body installation position setting button. Specifically, the pumping height set by the main body installation position setting button has three levels: high, standard, and low. When the pumping height is set to high, the output of the drainage pump 14 is set to high. When the pumping height is set to the standard, the output of the drainage pump 14 is set to the standard, and when the pumping height is set to the low, the output of the drainage pump 14 is set to low.

  In the drainage mode, the on-off valve 27 is opened, and at the same time, the drainage pump 14 is driven by the motor output set according to the pumping height set by the main body installation position setting button. 14 is stopped, and at the same time, the on-off valve 127 is closed.

  As described above, even when the pumping height detecting unit is used as an input unit for manually inputting the pumping height, the time for discharging all the accumulated water can be made substantially constant. In this example, as shown in FIG. 4, the operation of the drainage pump 14 is stopped when a predetermined time has elapsed from the start of operation by a timer. However, similarly to the above embodiment, a pump load detection unit is provided and a timer is provided. If the load on the drainage pump 14 detected by the pump load detecting means after driving the drainage pump 14 becomes less than a predetermined value, the control unit 12 may control the pump to stop. 14 is stopped when a certain time has elapsed from the start of operation by a timer, and when the load of the drainage pump 14 detected by the pump load detecting means becomes equal to or less than a predetermined value before the certain time has elapsed. The control unit 12 may control the drain pump 14 to stop.
