Here, when the flow path switching valve 11a is set to either mode A or mode B, the hot water from the hot water tank 10 is switched to flow to the electrolytic cell 13 through the water channel 14a, and the mode C is set. When it is done, the hot water from the hot water tank 10 is switched to flow into the water channel 14d and the water channel 14e.

  As shown in FIGS. 3 and 4, the butt washing nozzle 6 is provided so as to be retractable by a butt nozzle cylinder 31, and the bidet washing nozzle 7 is provided so as to be freely retracted and retracted by a bidet nozzle cylinder 32. The hot water from the hot water tank 10 is selectively supplied to the buttocks nozzle cylinder 31 and the bidet nozzle cylinder 32 by switching the flow path switching valve 11c by the operation of the operation unit 33. When supplied to the nozzle cylinder 31, as shown in FIG. 4, the buttocks cleaning nozzle 6 protrudes from the buttocks nozzle cylinder 31 to a predetermined position, and hot water is formed as cleaning water at the tip of the buttocks cleaning nozzle 6 at the protruding position. When hot water is supplied to the bidet nozzle cylinder 32 from the spout 6a, the bidet cleaning nozzle 7 protrudes from the bidet nozzle cylinder 32 to a predetermined position, and the hot water is washed at the protruding position.

Here, the nozzle cleaning pipe body 35 is connected to the downstream side of the pump 18 in the water passage 14c.

  The addition unit 12 adds an electrolysis promoter such as salt to the warm water from the warm water tank 10. As described above, when the electrolysis promoter is added to the hot water, the electrolysis efficiency is improved in the electrolytic cell 13, so that it is easy to generate hot water having the target pH, and it is possible to save compared with the case where no electrolysis promoter is added to the hot water. There are effects such as power generation.

  The electrolytic cell 13 has electrode chambers 13a and 13b separated by a diaphragm 13c, and is controlled by the energization control means 20 so that when one of the electrode chambers 13a and 13b is a cathode chamber, the other is an anode chamber. The When the electrolyzer 13 is energized by the energization controller 20, the hot water in the electrolyzer 13 is electrolyzed to generate electrolyzed water. At this time, the electrolyzed water generated in the cathode chamber is alkaline water. The electrolyzed water produced in the anode chamber becomes acidic water.

  The energization control means 20 performs energization control to the electrolytic cell 13 based on the detection signal of the human body detection means 19, and energizes the electrolytic cell 13 while detecting a person, and then detects a person. When there is no more current, the polarity of the voltage applied to the electrodes (not shown) in the electrode chambers 13a and 13b is reversed and energized for a certain period of time, and then the energization is stopped. Here, the polarity of the voltage applied to the electrodes in the electrode chambers 13a and 13b is reversed and the current is applied for a certain period of time in order to remove scales deposited on the electrodes in the cathode chamber. That is, when tap water or groundwater is used as the water supply source, the water supplied from the water supply source contains impurities such as calcium and magnesium in a small amount, and such water (hot water) is electrolyzed in the electrolytic cell 13. Then, impurities are deposited as scale on the electrode of the cathode chamber and the electrolysis ability is reduced, but here, by reversing the polarity of the electrode used as the cathode for a certain time and energizing as the anode, The scale is removed automatically.

  Hereinafter, the operation of the local cleaning device 1 in the present embodiment will be described. In addition, about operation | movement when the bidet washing | cleaning button (not shown) in the operation part 33 is pushed, it shall describe in ().

  First, the operation when the mode A is set at the previous use will be described. When the human body detecting means 19 detects a person, the detection signal is output to the energization control means 20, and the energization control means 20 energizes the electrolytic cell 13 with the electrode of the electrode chamber 13a as the cathode and the electrode of the electrode chamber 13b as the anode. Alkaline water is generated in the electrode chamber 13a, and acidic water is generated in the electrode chamber 13b. And the produced | generated alkaline water and acidic water are stored by the water storage tanks 15 and 17, respectively. Then, when a buttocks washing button (bidet washing button) (not shown) is pressed by the operation unit 33, the flow path switching valve 11b is opened and the pump 16 is driven, so that hot water that has become alkaline water in the water storage tank 15 flows. It flows into the buttocks washing nozzle 6 (bidet washing nozzle 7) via the path switching valve 11c and the buttocks nozzle cylinder 31 (bidet nozzle cylinder 32), and the buttocks washing nozzle 6 (bidet washing nozzle 7) is projected to a predetermined position and sprayed. It is jetted from the outlet 6a (jet outlet 7a) to the local body part. Thus, since the warm water which became alkaline water is injected as washing water to the human body part from the jet nozzle 6a (jet port 7a), in addition to the removal of the filth (solid substance) adhering to the human body part, it is contained in the filth. Fats and proteins can be removed. During this cleaning, alkaline water is generated in the electrode chamber 13 a and replenished to the water storage tank 15, and acidic water is generated in the electrode chamber 13 b and stored in the water storage tank 17.

  Subsequently, when a stop button (not shown) is pressed by the operation unit 33, the driving of the pump 16 is stopped and the flow path switching valves 11b and 11c are closed, and the butt washing nozzle 6 (the bidet washing nozzle 7) is turned to the butt nozzle. The cylinder 31 (the bidet nozzle cylinder 32) is retracted into the retracted posture. When the storage posture is reached, the flow path switching valve 11d is opened, the pump 18 is driven, and the hot water that has become the acid water in the water storage tank 17 is spouted through the nozzle cleaning pipe body 35 and the pipe path 36a. And then sprayed to the buttocks cleaning nozzle 6 and the bidet cleaning nozzle 7. Thus, since the warm water which became acidic water is sprayed as washing water from the spout 36a to the buttocks washing nozzle 6 and the bidet washing nozzle 7, solid matter such as filth adhering to both washing nozzles 6 and 7 is removed. In addition, both cleaning nozzles 6 and 7 can be sterilized. During this cleaning, alkaline water is generated in the electrode chamber 13 a and stored in the water storage tank 15, and acidic water is generated in the electrode chamber 13 b and supplied to the water storage tank 17. When the warm water that has become acid water is injected from the jet port 36a for a certain time (or a certain amount), the driving of the pump 18 is stopped and the flow path switching valve 11d is closed, and the cleaning by the nozzle cleaning means 8 is completed. To do.

  Thereafter, when no human is detected by the human body detection means 19, the polarity of the voltage applied to the electrodes of the electrode chamber 13a and the electrode chamber 13b is reversed by the energization control means 20, that is, the electrode in the electrode chamber 13a is used as an anode. The electrode is used as a cathode, and energization is performed for a predetermined time. If scale is deposited on the electrode in the electrode chamber 13a, the scale is removed. When a certain period of time elapses, the energization control means 20 stops energization of the electrolytic cell 13, and the flow path switching valves 11b and 11d are switched so that the hot water flows toward the water channel 14f, and the electrode chambers 13a and 13b and the water storage are stored. Hot water in the tanks 15 and 17 flows into the water channel 14f via the flow path switching valves 11b and 11d, and is drained into the toilet from a drainage channel (not shown).

  Next, the operation when mode B is set at the previous use will be described. When a human is detected by the human body detection means 19, the detection signal is output to the energization control means 20, and the energization control means 20 energizes the electrolytic cell 13 with the electrode of the electrode chamber 13a as the anode and the electrode of the electrode chamber 13b as the cathode. Acidic water is generated in the electrode chamber 13a, and alkaline water is generated in the electrode chamber 13b. Then, the generated acidic water and alkaline water are stored in the water storage tanks 15 and 17, respectively. When the butt washing button (bidet washing button) is pressed by the operation unit 33, the flow path switching valve 11b is opened, the pump 16 is driven, and the hot water that has become the acidic water of the water storage tank 15 is switched to the flow path. It flows into the buttocks washing nozzle 6 (bidet washing nozzle 7) through the valve 11c and the buttocks nozzle cylinder 31 (bidet nozzle cylinder 32), and the buttocks washing nozzle 6 (bidet washing nozzle 7) protrudes to a predetermined position, and the jet nozzle 6a. It is injected from the (spout port 7a) into the human body part. Thus, since the warm water which became acidic water is injected as washing water from the jet nozzle 6a (jet nozzle 7a) to the human body part, it is sterilized in addition to the removal of the filth (solid matter) adhering to the human body part. It can be performed. During this cleaning, acidic water is generated in the electrode chamber 13 a and replenished to the water storage tank 15, and alkaline water is generated in the electrode chamber 13 b and stored in the water storage tank 17.

  Subsequently, when the stop button is pressed by the operation unit 33, as in the mode A, the butt washing nozzle 6 (the bidet washing nozzle 7) is in the retracted posture. When the storage posture is reached, the flow path switching valve 11d is opened, the pump 18 is driven, and the hot water that has become the alkaline water in the water storage tank 17 is ejected through the nozzle cleaning pipe 35 and the pipe 36 through the jet 36a. And then sprayed to the buttocks cleaning nozzle 6 and the bidet cleaning nozzle 7. Thus, since the warm water which became alkaline water is sprayed as washing water from the spout 36a to the buttocks washing nozzle 6 and the bidet washing nozzle 7, solid substances such as filth adhering to the washing nozzles 6 and 7 are removed. In addition, fats and proteins contained in the filth can be removed. During this cleaning, acidic water is generated in the electrode chamber 13 a and stored in the water storage tank 15, and alkaline water is generated in the electrode chamber 13 b and supplied to the water storage tank 17. When the warm water that has become alkaline water is injected from the jet port 36a for a certain time (or a certain amount), the driving of the pump 18 is stopped and the flow path switching valve 11d is closed, and the cleaning by the nozzle cleaning means 8 is completed. To do.

  Thereafter, when no human is detected by the human body detection means 19, the polarity of the voltage applied to the electrodes of the electrode chamber 13a and the electrode chamber 13b is reversed by the energization control means 20, that is, the electrode in the electrode chamber 13a is used as a cathode. The electrode is used as an anode for energization for a certain time, and if a scale is deposited on the electrode in the electrode chamber 13b, the scale is removed. When a certain period of time elapses, the energization control means 20 stops energization of the electrolytic cell 13, and the flow path switching valves 11b and 11d are switched so that the hot water flows toward the water channel 14f, and the electrode chambers 13a and 13b and the water storage are stored. Hot water in the tanks 15 and 17 flows into the water channel 14f via the flow path switching valves 11b and 11d, and is drained into the toilet from the drainage channel.

  Next, the operation when mode C is set at the previous use will be described. Mode C does not energize the electrolytic cell 13 based on the human body detection means 19 as in the modes A and B, and performs the same operation as that of Patent Document 3 described in the “Background Art” column. is there.

  That is, when the butt washing button (bidet washing button) is pressed by the operation unit 33, the flow path switching valve 11a is switched so that the warm water from the warm water tank 10 flows into the water channel 14d, and the pump 16 is driven, so that the warm water flows. It flows into the buttocks washing nozzle 6 (bidet washing nozzle 7) via the path switching valve 11c and the buttocks nozzle cylinder 31 (bidet nozzle cylinder 32), and the buttocks washing nozzle 6 (bidet washing nozzle 7) is projected to a predetermined position and sprayed. It is jetted from the outlet 6a (jet outlet 7a) to the local body part.

  Subsequently, when the stop button is pressed by the operation unit 33, as in the mode A, the butt washing nozzle 6 (the bidet washing nozzle 7) is in the retracted posture. In the retracted posture, the flow path switching valve 11a is switched so that the hot water from the hot water tank 10 flows into the water passage 14e and the pump 18 is driven, and the hot water is sprayed through the nozzle cleaning pipe body 35 and the pipe passage 36. Sprayed from the outlet 36a to the buttocks cleaning nozzle 6 and the bidet cleaning nozzle 7. When hot water is injected from the outlet 36a for a fixed time (or a fixed amount), the driving of the pump 18 is stopped and the flow path switching valve 11a is closed, and the cleaning by the nozzle cleaning means 8 is completed.

  As described above, in this embodiment, if the mode A or B is set, the electrolysis cell 13 is energized by the energization control unit 20 while the human body detection unit 19 is detecting a person. Therefore, the electrolyzed water that becomes the cleaning water can be generated in the electrolytic cell 13 before being sprayed from the local cleaning nozzle 5 to the local body part and before being sprayed from the nozzle cleaning means 8 to the local cleaning nozzle 5, and as a result , The cleaning effect by electrolyzed water, that is, the pH required to sufficiently exert the bactericidal effect when the electrolyzed water is acidic water, when the electrolyzed water is alkaline water, the effect of removing fat, protein, etc. contained in the filth The electrolyzed water can be stably jetted from the local cleaning nozzle 5 and the nozzle cleaning means 8.

  In this embodiment, the water storage tank 15 is provided on the upstream side of the flow path switching valve 11b, and the water storage tank 17 is provided on the upstream side of the flow path switching valve 11d.
