The generated sterilizing water or purified water is supplied to the flow rate controller 108, and the flow controller 108 regulates the flow rate of purified water for washing or sterilizing water according to the control of the controller 106 and supplies it to the spray nozzle. .

Subsequently, the spray nozzle unit 110 sprays the purified water or sterilized water supplied through the flow control unit 108 into the toilet bowl using the spray nozzle to clean the inside of the toilet bowl at regular time intervals (S507).

Thereafter, the injection is automatically terminated when the injection time of the purified or sterilized water passes a preset period of time (S508 to S509). At the end of spraying, both purified/sterilized water generation and water supply are turned off.

In this way, by automatically washing the toilet at regular intervals, it is possible to maintain an optimal sanitary condition at all times.

According to the present invention described above, the inside of the toilet bowl is cleaned and sterilized with purified water and sterilized water before and after using the bidet through the change in the illumination of the bidet installation space using the illumination using the optical sensor, so that separate chemicals are not used. By keeping the bidet clean at all times without having to do so, it improves the sanitary environment and prevents the user's inconvenience and waste of time due to manual toilet cleaning.

In addition, by controlling the cleaning and sterilization of the toilet by interlocking the change in illumination with time, the bidet can always be kept clean and germ-free even when the bidet is not used for a long time.

Similarly, by automatically cleaning and sterilizing the inside of the toilet bowl with sterilizing water in conjunction with the seating sensor, inconvenience and time wastage due to manual toilet cleaning by the user is prevented.

Although the invention made by the present inventors has been specifically described according to the above embodiments, the present invention is not limited to the above embodiments, and it is common knowledge in the art that various changes can be made without departing from the gist of the present invention.
