FIG. 1 shows a toilet apparatus according to one embodiment of the present invention. An electrolytic tank 3 for producing sterilized water is provided in a casing of a hot water washing means 2 attached to a toilet body 1. A controller 4 as control means for controlling the electrolysis and the like;
A blower unit 5 as a drying unit including an air heating unit such as an electric heater is housed therein.

The electrolytic bath 3 is provided below the toilet seat 6.
A toilet sterilizing nozzle 7 for discharging the sterilized water generated by the toilet head toward the rim portion of the toilet body 1 is provided over substantially the entire circumference of the toilet seat 6. A germicidal water spout 8 for discharging germicidal water generated by the electrolytic cell 3 toward a hot water washing nozzle (not shown) for spraying washing water is provided. When the toilet lid 9 is in the closed state, the toilet seat 6 and the toilet body 1
An atomizing nozzle 10 for spraying sterilizing water toward the ball surface is provided.

FIG. 2 is a schematic view of a sterilizing water flow path of the toilet apparatus of FIG. 1. Tap water is branched into a hot water washing flow path 11a and a sterilizing water flow path 11b. 11 a is opened, the tap water is heated by the hot water tank 13, and the hot water washing nozzle 14 is heated.
Is discharged toward the human body, while the sterilization of the toilet bowl device is performed by the solenoid valve 15 provided in the sterilization water flow path 11b.
Is opened and sterilized water is generated by the electrolytic cell 3,
By means of the one-way switching valve 16, the toilet sterilizing nozzle 7 and the sterilizing water spout 8 or the atomizing nozzle 10 or the hot water tank 1
Discharge sterile water toward 3.

The operation of discharging the sterilizing water for sterilizing the toilet apparatus is performed by a use state detecting means of the toilet apparatus such as a human body detecting means provided in the hot water washing means 2 as described later. It operates based on a signal. For example, after a predetermined time after the use of the hot water washing means 2 is stopped,
The four-way switching valve 16 is provided with the toilet sterilizing nozzle 7 and the sterilizing water spout 8.
The solenoid valve 15 is opened while communicating with the toilet, and the tap water is spouted toward the toilet body 1 and the hot water washing nozzle 14 for a predetermined time while generating sterilized water containing hypochlorous acid by the electrolytic cell 3. Thereafter, the four-way switching valve 16 is communicated with the atomizing nozzle 10, and the toilet lid 9 is moved to the closed state by an electric opening / closing means (not shown) so that the sterilizing water is discharged toward the toilet seat 6 for a predetermined time. Then, warm air is blown out from the blower unit 5 for a predetermined period of time to dry the surface of the sterilized water to be discharged.

The toilet body 1 and the hot water washing nozzle 14
Since the frequency of sterilization of the hot water tank 13 is lower than that of the toilet seat 6, the switching to connect the four-way switching valve 16 to the hot water tank 13 is performed by the user because it is determined that the sterilization of the hot water tank 13 is necessary. In the case where an instruction operation is performed, in this case, the solenoid valve 12 is closed and the four-way switching valve 16 is in communication with only the hot water washing channel 11a so that the sterilizing water flows into the hot water tank 13. The electromagnetic valve 15 is opened, and the tap water is caused to flow into the hot water tank 13 and discharged from the hot water washing nozzle 14 while generating sterilizing water containing hypochlorous acid by the electrolytic cell 3. Then, after a lapse of time sufficient to sufficiently sterilize the hot water tank 13, the electromagnetic valve 15 is closed and the electromagnetic valve 12 is opened to replace the sterilized water flowing into the hot water tank 13 with tap water.

FIG. 3 shows the case of producing sterilized water by electrolysis.
FIG. 4 is a diagram showing a mechanism of the present invention. Water flowing into electrolytic cell 3
A voltage is applied between the electrode members 17 arranged at the opposite electrode via water.
When this occurs, electrolysis occurs, and hydrogen gas is applied to the surface of the cathode 17a.
SU_TwoOccurs. In addition, oxygen gas is applied to the surface of the anode 17b.
Su O_Two, Chlorine gas Cl_TwoIs generated and chlorine gas Cl _TwoIs OH^-
Instantaneously reacts with hypochlorite (HCl
O).

In the above toilet apparatus, the solenoid valve 15 is opened and the sterilizing water containing hypochlorous acid is supplied to the toilet sterilizing nozzle 7,
After discharging water from the sterilizing water discharge port 8 or the atomizing nozzle 10, the residual water on the surface to be discharged is dried by driving the blower unit 5 for a predetermined period of time, so that water necessary for the growth of bacteria can be removed. In addition, the antifouling effect can be further improved.

In the above-described embodiment, the case where the electrolytic tank 3 and the controller 4 are housed in the casing of the hot water washing means 2 has been described. However, as shown in FIG. The tank 3 and the controller 4 may be arranged so that the sterilizing water generated by the electrolytic tank 3 may be discharged from the toilet sterilizing nozzle 7, and may be placed at the rear of the toilet body 1 as shown in FIG. The electrolytic bath 3 and the controller 4 are arranged in the toilet flush water tank 19 arranged in the cover casing 18 so that the sterilizing water generated by the electrolytic bath 3 is supplied to the toilet body 1 through a normal toilet flush water flow path. Alternatively, as shown in FIG. 6, the electrolytic bath 3 is housed in the toilet lid 9, and sterilized water generated by the electrolytic bath 3 is directed from the atomizing nozzle 10 to the toilet seat 6 or the toilet body 1. It may be water discharge.

FIG. 7 is a control flow of the timing of generation and discharge of sterilized water, which relates to an apparatus for detecting the usage state of a toilet by a sensor for detecting a user sitting on a toilet seat.

As shown in the flow chart of FIG. 7, when the power of the apparatus is turned on, a timer T starts (S101).
When the seating sensor detects a human body (S102Y), the counter C is incremented (S103). And
The seating sensor stops detecting the human body (S104Y),
When it is determined that the use of the toilet device has been completed, the timer T
It is determined whether or not two hours have elapsed (S105). If two hours have elapsed (S105Y), the counter C indicates "2".
It is determined whether it is less than or equal to “2” (S106).
Y) The frequency of use of the toilet device is low, and the number of times that the cleaning operation for cleaning the toilet is performed during the two hours measured by the timer T is also small, and there is a possibility that various germs in the toilet device have propagated. Therefore, sterilizing water is generated and spouted (S107),
The timer T and the counter C are cleared to see the timing of the next generation and discharge of sterilized water (S108).

Even if it is determined in S105 that two hours have elapsed, if it is determined in S106 that the counter C is not less than "2" (S106N), the frequency of use of the toilet bowl device is high. Naturally, the number of times the washing operation for toilet flushing was performed during the two hours counted by the timer T was also large, and there was a high possibility that the germs in the toilet bowl apparatus did not propagate very much. Without resetting, the counter C is reset (S109), and from the time measured by the timer T,
0.5 hours is subtracted (S110), and apparently timer T is 2
Extend the time before timing. If the frequency of use of the toilet bowl device within the extended time period is low, S1
At 06, the counter C is determined to be "2" or less, so that sterilizing water is generated and spouted.

The step S106 may be omitted. In this case, the seat is not seated, and sterilizing water is generated and discharged every two hours.

In FIG. 7, the state of use of the toilet device is detected based on a signal from the seat sensor. However, instead of the seat sensor, a reflection type infrared sensor for detecting the proximity of the toilet device is used. The state of use of the toilet apparatus may be detected by a sensor or the like, or the supply of flush water to the toilet may be detected. As means for detecting the supply of washing water, as shown in FIG. 5, when detecting the supply of washing water from the toilet washing water tank 19 to the toilet, it can be configured by detecting the operation of the washing water discharge lever. In the case of a flush valve system that does not include a toilet flush water tank, it can be configured by detecting the flow of flush water in the flush water discharge channel with a flow rate sensor or a pressure sensor,
