According to the present invention, by sterilizing the injection nozzle by the sterilizing means, it is possible to prevent the occurrence of contamination by pathogenic bacteria and keep the injection nozzle in a sterilized state for a long time.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. The same or corresponding parts as in the conventional example of FIG. 6 are denoted by the same reference numerals, and redundant description will be omitted.

FIG. 1 to FIG. 3 show a sterilizing apparatus for a flush toilet seat according to a first embodiment of the present invention. The first embodiment shows a plurality of (five) units such as a shared toilet. This is a case where the flush toilet seat 1 is installed on the toilet 2 respectively.

As shown in FIG. 1, a water storage tank 9 for storing tap water is provided at a distal end side of a main water supply pipe 8 connected to a water pipe (not shown). Vessel 10
Is attached. The disinfectant supplier 10 contains a disinfectant (ozone gas, ozone-containing water, strongly acidic water, hypochlorous acid, chloric acid, bromine compound, electrolyzed water, etc.). Is automatically supplied to the water tank 9 and the sterilizing agent is mixed with the tap water stored in the water tank 9 to produce washing water having a bactericidal concentration harmless to the human body (for example, ozone water). 0.8 PPM to 1 PP
M). And the water distribution pipe 11 which connects the water storage tank 9 and each toilet 2 is provided, respectively, and the water supply pipe 12 which connects each water distribution pipe 11 and the injection nozzle 7 of each washing toilet seat 1 is provided.

FIG. 2 shows the spray nozzle 7 in the cleaning toilet seat 1.
The jet nozzle 8 is configured such that a tip end having an injection hole 7a is rotatable 180 ° to the left or right, and when a sterilization switch on the main body operation unit 6 of the cleaning toilet seat 1 is pressed, cleaning is performed. After sliding to the position for spraying water, the tip having the spray hole 7a is rotated left or right by 180 °.

FIG. 3 is a detailed view of the toilet seat 4 in the flush toilet seat 1. The toilet seat 4 is provided with a horseshoe-shaped injection tube 13 connected to a water supply pipe 12 along the inner surface thereof. A large number of injection holes 13 a are provided at appropriate intervals toward the inner surface of the toilet seat 4.

The operation of the apparatus for sterilizing a flush toilet seat according to the present embodiment having the above configuration will be described. First, a certain amount of disinfectant is automatically supplied from the disinfectant supply device 10 to the water storage tank 9, so that washing water having a concentration that is harmless to the human body is produced inside the water storage tank 9. Then, when the user presses the cleaning switch on the main body operation section 6 of the cleaning toilet seat 1, the spray nozzle 7 is slid to the position where the cleaning water is sprayed, and then the sterilizing cleaning water is distributed from the water storage tank 9. The water is jetted from the cleaning nozzle 7 of the cleaning toilet seat 1 through the water pipe 11 and the water supply pipe 12 to clean the anus and the like of the user. Next, when the user presses the stop switch on the main body operation unit 6 of the cleaning toilet seat 1 or rises from the cleaning toilet seat 1, the ejection nozzle 7
Is rotated 180 ° to the right or left, and sterilizing water is sprayed from the spray nozzle 7. Further, sterilizing cleaning water is guided to the jet tube 13 provided also on the inner surface of the toilet seat 4, and the sterilizing cleaning water is jetted from the jet tube 13. Thus, the inner surfaces of the toilet 2 and the toilet seat 4 are sterilized.

According to the first embodiment, not only the jet nozzle 7, the toilet seat 2, and the toilet bowl 2 of the cleaning toilet seat 1 can be sterilized, but also the water storage tank 9, the water distribution pipe 12, and the water supply pipe 13 can be sterilized. As a result, the entire cleaning system can be kept in a sterilized state for a long time.

In the first embodiment, the case where the flush toilet seat 1 is installed on each of a plurality (five) of toilets 2 such as a shared toilet is described. The present invention can be applied to a flush toilet seat to be installed. In the first embodiment, the case where the number of the injection nozzles 7 is one has been described. However, the present invention can be applied to the case where the number of the injection nozzles 7 is two for the anus and the bidet.

FIG. 4 is a view showing a sterilizing device for a flush toilet seat according to a second embodiment of the present invention. A heater 14 is provided. The heater 14 for sterilization is fitted with a heating element 15 made of a circular ceramic having a plurality of injection holes 7a at the tip of the injection nozzle 7 and a sensor provided with the heating element 15 on the toilet seat 4 (see FIG. Connected to a battery (not shown) through a heater (not shown), the heater 14 is heated by the current flowing through the heating element 15, and is provided on the toilet seat 4 when the user sits on the toilet seat 4. Heating element 1 by sensor
5 is temporarily cut off, the heating of the heater 14 is stopped, and the temperature of the cleaning water is prevented from becoming too high.

In the second embodiment, when the user rises from the toilet seat 4 after stool, a current is applied to the heating element 15 of the heater 14 and the heater 14 starts heating. Thereby, the injection nozzle 7 and the washing water inside thereof are heated to, for example, about 65 ° C. to 80 ° C. which has a sterilizing action.

In the case of a cleaning toilet seat having a self-cleaning function, the washing water supplied to the injection nozzle 7 at the time of self-cleaning is sterilized by a heater for heating the cleaning water supplied to the injection nozzle 7 at a temperature that is comfortable for the human body. It may be heated to about 65 ° C. to 80 ° C.
