The present invention relates to a system for disinfecting bidets. More particularly, the present invention relates to a water tank for generating sterilizing water and using the generated sterilizing water, a water tank for storing cleaning water, a cleaning channel for discharging the cleaning water through the cleaning nozzle, a bidet channel for leaving the cleaning water to the bidet nozzle, The present invention relates to a disinfecting system for a bidet that disinfects the surface of a main body and injects disinfecting water into a pot with a bidet.

As living standards improve, households using bidet are increasing. The bidet typically stores tap water as a washing water in a water tank, and performs a predetermined operation including a washing function and a bidet function by using the washing water stored in the water tank.

When the tap water is used as washing water, since the tap water contains a sterilizing component such as chlorine, the propagation of various microorganisms including bacteria and fungi is suppressed.

However, the tap water stored in the water tank gradually dissolves the germicidal component such as chlorine as time elapses, so that microorganisms propagate over time to the washing water stored in the water tank.

For example, when the user does not use the bidet for more than two or three days due to traveling abroad or traveling for a long period of time, the sterilizing component of the tap water stored in the water tank is stored in the water tank, The microorganisms start to multiply in the washing water stored in the washing water.

That is, the bidet is sanitarily safe by washing it with water without using toilet paper after use.

However, if a user performs a cleaning function or a bidet function while a microorganism harmful to the body propagates in a water tank of a bidet, etc., the microorganism may remain in the user's body and reproduce, resulting in the user's health being deteriorated &Lt; / RTI > Furthermore, in the case of women, the genital part of the body is susceptible to microorganisms.

Therefore, there is a demand for a bidet having an excellent sterilizing function. In other words, it is possible to sterilize the inside of the water tank in which the washing water is stored, as well as the surface of the nozzle body, the bidet channel which is a path through which the washing water from the bidet nozzle and the washing channel, And a bidet having a sterilizing function capable of sterilizing the surface of the nozzle body having the bidet nozzle.

In addition, there is a need for a bidet capable of sterilizing the pottery in which the bidet is installed together with the sterilizing function of the bidet described above, because the pottery in which the bidet is installed can reproduce many microorganisms harmful to the body including excretion from the body. It is a fact that it is emerging.

As a prior art which is installed in a bidet and performs a sterilization operation, Korean Patent Laid-Open Publication No. 10-2011-0129258 (entitled "Bidet capable of sterilizing euro," published Dec. 1, 2011) is known.

Then, the sterilized water generated is discharged through the cleaning nozzle to sterilize the flow path of the cleaning nozzle or to flow out through the bidet nozzle, thereby sterilizing the flow path of the bidet nozzle.

The sterilized water is sent to a nozzle sterilizer, sterilizing the surface of the nozzle body having the cleaning nozzle and the bidet nozzle, and discharging the sterilized water to the potter sterilizer through a pump and spraying the pottery Sterilize.

However, in the prior art described above, the cleaning water stored in the water tank is supplied to the sterilizing water generating module to generate sterilizing water, and the flow path of the cleaning nozzle, the flow path of the bidet nozzle, the surface of the nozzle body, And the inside of the water tank in which the washing water is stored most is not sterilized.

Therefore, even if the sterilizing function is performed by the sterilizing water generated in the sterilizing water generating module, there is a high possibility that the microorganisms still remain in the water tank and reproduce. Therefore, when the user uses the cleaning function or the bidet function, There was a problem that the microorganisms were left in the body.

In addition, the above-described prior art has a problem in that the cleaning water stored in the water tank is supplied to the sterilizing water generating module to generate sterilizing water, and the flow path of the cleaning nozzle, the flow path of the bidet nozzle and the surface of the nozzle body are cleaned The remaining sterilizing water is not removed.

Therefore, after the bidet performs the sterilizing function, the user performs the cleaning function or the bidet function with the sterilization water remaining in the inside of the bidet at the initial stage of using the cleaning function or the bidet function.
