A toilet is a device that allows the user to sit down and use the toilet. Recently, toilets equipped with a bidet have been widely used for hygiene purposes. A bidet is a device that cleans the user's local area by spraying water after toileting. It has the advantage of keeping the local area clean because it cleans with water instead of using toilet paper.

A toilet is typically equipped with a water tank, bidet, and operating unit. When the user presses the lever after using the toilet, the water in the toilet is discharged along with the toilet and the water in the water tank is filled into the toilet. Additionally, when the user operates the bidet by manipulating the control panel, the nozzle installed within the bidet body moves to the front of the bidet body and sprays washing water on the user's local area.

However, in a toilet that operates in this way, if the feces in the toilet are not flushed out at once, the feces may stick to the inner wall of the toilet, and water is always accumulated in the toilet bowl, so various microorganisms can live and proliferate, so it is desirable for hygiene. can't do it Therefore, the user has the inconvenience of having to periodically clean the toilet by adding a disinfectant or cleaning solution inside the toilet.

In order to alleviate this inconvenience to users, devices for injecting sterilizing liquid or cleaning liquid into the inner wall of the toilet have recently been prepared and used. However, the existing disinfectant solution injection device cannot spray the disinfectant solution onto the entire inner wall of the toilet, so the entire inner wall of the toilet was not sufficiently sterilized.
