As described above, the core flow channel 452 can utilize the drop according to the height of the nozzle core 450 and at the same time increase the rotational force and rotation speed of the washing water sprayed by using the spiral flow channel structure.

Next, an operation method using the bidet 1000 having the sterilizing water spraying nozzle of the present invention will be described.

The sterilization method of the bidet 1000 in the standby state is as follows.

The washing water passing through the reduced pressure water supply module (200) flows into the washing water storage part (100). The inflowing wash water is maintained at the inflow temperature or heated to a low temperature of about 40 degrees through the heater 120.

In the case where cleaning is performed using a separate seating sensor disposed on the toilet seat where the bidet 1000 is installed, the sterilizing module 110 can be controlled to be in an unoperated state.

On the other hand, when the washing water stored in the washing water storage unit 100 for a long time is stored in an unused state, the washing water is volatilized into the atmosphere as time elapses, so that an environment in which general bacteria can easily reproduce is formed. At this time, the chlorine concentration of the washing water in the washing water storage part 100 is controlled to 0.5 ppm, which is the normal water level, through the operation of the sterilizing module 110 mounted on the washing water storage part 100, . As a result, it is possible to cleanly use the cleaning water which is always maintained at a uniform chlorine concentration when cleaning the local area and the anus.

The chlorine concentration of the washing water in the washing water storage part 100 can be continuously increased due to the operation of the sterilizing module 110 which is continued when the bidet 1000 is not used for a long time.

Chlorine concentration is 0.3 ~ 0.5ppm in the case of water supply, and chlorine is killed within 1 ~ 2 hours when it is generally opened and opened. The washing water storage part 100 of the bidet 1000 according to the present invention can maintain a hermetic state for 5 to 6 hours so that the concentration of the general bacteria can be maintained at 0.2 ppm or more.

The wash water obtained through the decompression water supply module 200 is stored in the wash water storage part 100 without operating the sterilization module 110 for 5 to 6 hours. Thereafter, the chlorine concentration of the wash water stored through the sterilization module 110 operation can be maintained at 0.5 ppm.

Thereafter, when the user again receives the water from the washing machine, the sterilizing module 110 is operated after 6 hours from the receipt of the water, so that the chlorine concentration of the washing water stored in the washing water storage part 100 is always low Keep the minimum chlorine concentration. The check at intervals of 6 hours after the use of the bidet (1000) follows the control module (500). In the present invention, the waiting time is defined as the waiting time after the water is newly introduced and is unused.

The sterilization process after using the bidet 1000 is as follows.

The control module 500 controls the flow path-changing valve 300 to supply the washing water to the self-cleaning nozzle 410 to clean the cleaning nozzle 401 and to remove the foreign matter of the nozzle module 400 Remove.

At the same time, power is applied to the sterilizing module 110 of the washing water storage unit 100, and electrolysis of the washing water occurs on the surface of the pole plate 112 of the sterilizing module 110. In the electrolysis process of the sterilizing module 110, air bubbles such as oxygen may be generated on the surface of the electrode plate 112. The bubbles lower the electrolytic efficiency by reducing the contact area with the washing water.

Meanwhile, in the bidet 1000 according to the present invention, the electrode plate 110 of the sterilizing module 110 may be placed on the rotating flow path of the washing water. In this case, when the washing water flows out to the flow path changing valve 300 The bubbles can be discharged together with the washing water discharged to the outside, thereby maximizing the electrolysis efficiency. Here, the washing water passes between the pole plates 110 of the sterilizing module 110 and contains a germicidal substance such as hypochlorite ions. The washing water containing the germicidal substance removes foreign matter and sterilization outside the nozzle module 400 do.

As described above, the bidet having the sterilizing water spraying nozzle of the present invention eliminates the problem that the cleaning efficiency is drastically lowered due to fusion residue when the foreign matter is fused to the sterilizing water spraying nozzle while using the bidet, The present invention is not limited to the above-described specific embodiments, and various changes and modifications may be made without departing from the scope of the present invention. It will be apparent to those skilled in the art that numerous modifications and variations can be made in the present invention without departing from the spirit or scope of the appended claims. And equivalents should also be considered to be within the scope of the present invention.
