  According to the structure of claim 5 of the present invention, the electrode is made of silver or a silver alloy, so that silver ions are eluted in the wash water. It is possible to perform sterilization of the inner surface and the like.

  According to the configuration of claim 6 of the present invention, by attaching a spare outlet to the generator, if power is supplied from this spare outlet to the sanitary washing toilet seat, there is no need to add an outlet by adding the generator, The generator can be installed more easily.

  An embodiment according to the present invention will be described first with reference to FIG. 1. Reference numeral 1 denotes a sanitary washing toilet seat which is detachably or detachably mounted on a Western-style toilet bowl 2. It pivots to open and close freely.

  In the main body case 3, for example, as shown in FIG. 2, a hot water storage tank 7 in which a heater 6 is installed, a water supply pipe 8 for supplying tap water to the tank, and the hot water storage tank The anal nozzle 9 and the bidet nozzle 10 for injecting hot water in the body 7 toward the local part of the human body are mainly housed and arranged.

  The water supply pipe 8 is connected to a water pipe 14 such as city water via a metal ion generator 11, a flexible pipe hose 12, a branch tap 13, a strainer 15, a check valve 16, A water stop solenoid valve 17, a pressure reducing valve 18, and a flow rate adjusting valve 19 are sequentially mounted.

  The anal nozzle 9 and the bidet nozzle 10 are connected to the hot water storage tank 7 through a switching valve 20 formed integrally with the flow rate adjusting valve 19, and the flow rate adjusting valve 19 and the switching valve are connected. 20 is rotationally driven by a motor 21 and a predetermined flow rate of cleaning water is supplied to one of the nozzles.

  On the other hand, the generator 11 is detachably or detachably connected to the water supply connection port 22 of the water supply pipe 8 exposed on the side surface of the main body case 3, as shown in FIG. Similarly, a spare outlet 24 is mounted at a position higher than the connection position of the water supply connection port 22, for example, at the upper back of the case 23, and a power switch 25, a power lamp 26, a notification lamp 27, etc. are arranged on the upper surface. The operation panel 28 is arranged.

  With these configurations, the auxiliary outlet 24 is disposed at a position higher than the connection position of the water supply connection port 22, so that even if water leaks from the connection portion of the water supply connection port 22 for some reason, the auxiliary outlet 24 is connected to the auxiliary outlet 24 as much as possible. As shown in FIG. 1, for example, a power plug 51 of the generator 11 is connected to an outlet 50 provided on the wall surface of the toilet. If the power plug 52 of the sanitary washing toilet seat 1 is connected to the spare outlet 24, the generator 11 can be installed relatively easily without adding the outlet 50 and the like.

  Further, in the case 23, as shown in FIG. 4, an electrolytic water channel 31 having a connection fitting 29 for connecting the piping hose 12 at one end and a connection fitting 30 for connecting to the water supply fitting 22 at the other end is provided. The water flow sensor 32 and the metal ion generator 33 are sequentially connected to this electrolytic water channel.

  The metal ion generator 33 is formed of a circular arc, for example, SUS304 type stainless steel, facing the periphery of the metal electrode 34 formed of cylindrical silver or silver alloy, copper, or silver-copper alloy. The counter electrode 35 is disposed, and for example, by applying a positive potential to the metal electrode 34 and a negative potential to the counter electrode 35, silver ions, copper ions, etc. are contained in the washing water passing through the water passage 36 by electrolysis. The metal ions are eluted.

  Reference numeral 37 denotes a control circuit. As shown in FIG. 5, when the water flow sensor 32 is connected to the input port of the control unit 38 constituted by a microcomputer or the like and the water flow sensor 32 detects water flow when the power switch 25 is turned on. A predetermined DC current is applied between the metal electrode 34 and the counter electrode 35. When the power switch 25 is turned on, the power lamp 26 is turned on, and the loading energization time between the metal electrode 34 and the counter electrode 35 is counted. The information is stored in a memory 39 such as a non-volatile memory, and when the loading energization time reaches a preset consumption time of the metal electrode 34, the notification lamp 27 is turned on to notify the replacement time of the metal electrode 34. doing.

  Further, the control circuit 37 is connected with a leakage breaker circuit 41 incorporated in the well-known sanitary washing toilet seat 1 between the power plug 51 and the power supply circuit 40. The spare outlet 24 is connected to 40, and by these configurations, it is possible to eliminate the incorporation of the earth leakage cutoff circuit in the sanitary washing toilet seat 1, and the cost of the sanitary washing toilet seat can be reduced.

  The control circuit 37 detects the amount of water flow based on the output of the water flow sensor 32 and adjusts the amount of current (applied voltage or applied current) applied between the metal electrode 34 and the counter electrode 35 in accordance with the amount of water flow. Thus, the concentration of metal ions eluted in the washing water can be controlled substantially uniformly without being affected by the amount of water. The metal ion concentration may be configured to be set stepwise or steplessly by providing a switch for setting a concentration (not shown).

  Thus, when the sanitary washing toilet seat 1 is washed while the power switch 25 of the generator 11 is turned on, the water stop solenoid valve 17 in FIG. The valve 19 and the switching valve 20 are driven to rotate, and washing water having a set flow rate set by the flow rate adjusting valve 19 is ejected from the anal nozzle 9 or the bidet nozzle 10.

  Simultaneously with the ejection of the washing water, the water flow sensor 32 of the generator 11 detects the water flow, and a predetermined current is applied between the metal electrode 34 and the counter electrode 35 by the control unit 38 so that silver ions or the like are contained in the washing water. The metal ions are eluted.

  Thereby, the metal ions eluted in the wash water can suppress the growth of bacteria in the hot water storage tank 7 and the water supply pipe 8 in the sanitary washing toilet seat 1, and can also sterilize local parts of the human body and washing nozzles. Is.

  In addition, when connecting the generator 11 to the existing sanitary washing toilet seat 1, after stopping the faucet of the branch tap 13 and removing the piping hose 12 from the water supply connection port 22, the generator 11 is connected to the water supply connection port. And the piping hose 12 is connected to the connection fitting 29. For example, the power plug 51 of the generator 11 is inserted into the outlet 50, and the power plug 52 of the sanitary washing toilet seat 1 is connected to the spare outlet 24 of the generator 11. If plugged in, it can be installed relatively easily.
