Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a configuration diagram of an embodiment of the human body local cleaning device of the present invention. Reference numeral 1 denotes a water shut-off valve that draws tap water into the human body local cleaning device. Reference numeral 2 denotes a water amount adjusting valve for adjusting the flow rate of the drawn tap water. Reference numeral 3 denotes an ultrasonic irradiation unit that irradiates ultrasonic waves to generate sterilized water. Reference numeral 31 denotes an ultrasonic vibrator as ultrasonic irradiation means, which is driven by a drive power supply (not shown) to irradiate ultrasonic waves. Reference numeral 4 denotes a heat exchanger for heating the tap water whose flow rate has been adjusted, adjusting the temperature, and adjusting the temperature of the washing water to an appropriate value. Reference numeral 5 denotes cleaning water discharge means which is extended by the water pressure of the cleaning water and discharges the cleaning water to clean the human body part. Reference numeral 6 denotes a control unit that performs the above control.

Normally, when the user is in a local washing mode which can be used, when the user presses a switch (not shown), the control unit opens the water shutoff valve 1 and adjusts the water amount by the water amount adjusting valve 2, and the heat exchanger The cleaning water is discharged from the discharge means 5 by heating and adjusting the temperature by the step 4. At this time, the operation of the ultrasonic irradiation unit 3 is stopped. Next, the mode is shifted to the channel sterilization mode at regular intervals, and the channel and the washing water discharge unit are sterilized. First, the mode is shifted to the channel sterilization mode by the timer in the control unit 6 to display that it is unusable. Next, the control unit opens the water shut-off valve 1 to allow water to flow through the ultrasonic irradiation unit and fill the water, and sends a generation command of sterilizing water to the ultrasonic irradiation unit, whereby the ultrasonic vibrator 31 is driven and ultrasonic waves are transmitted. Irradiate.

The mechanism of purification by ultrasonic radiation in the ultrasonic irradiation section 3 is not known in detail, but is considered as follows. When strong ultrasonic waves are irradiated into water, pressure changes propagate in the water, but extremely large pressure drops and rises occur in a very short time. When the pressure decreases, water and dissolved gas evaporate due to the rapid pressure decrease, and minute bubbles called cavitation are generated. The bubble then becomes locally hot due to adiabatic compression the next time the pressure is increased. The temperature at this time is said to be several thousand degrees to ten thousand degrees, and it is said that various radicals are generated around this minute high-temperature spot. It is considered that the sterilization effect is obtained by the high temperature and the radical.

This apparatus shifts to the channel sterilization mode at regular intervals, as in the first embodiment, and sterilizes the channel and the washing water discharge means. First, the mode is shifted to the channel sterilization mode by the timer in the control unit 6 to display that it is unusable. This display can be performed by a lamp such as an LED, for example. Next, the control unit opens the water shut-off valve 1 to allow water to flow through the ultrasonic irradiation unit and fill the water, and sends a generation command of sterilizing water to the ultrasonic irradiation unit, whereby the ultrasonic vibrator 31 is driven and ultrasonic waves are transmitted. Irradiate. By irradiating the ultrasonic waves, sterilizing water is generated in the ultrasonic irradiation unit 3. The heat exchanger 4, the cleaning water spouting device 5, and the water pipe are sterilized and washed by slowly passing the sterilized water at a low flow rate. After completion of sterilization of the flow path and the washing water discharge means, tap water is introduced and rinsed, then the display of the flow path sterilization mode is stopped, and the flow path sterilization mode is ended.

When using a hot water storage tank, there are several types. First, there is a case where hot water of an appropriate temperature is stored.

In addition, since there is a possibility that various germs may propagate, it is very effective to provide sterilizing water by providing ultrasonic irradiation means here to keep the hot water storage tank sanitary. By providing the means, no additional space is required. There is another type of hot water storage tank that stores hot water, but in this case, since the temperature is relatively high, sterilization of the hot water storage tank is not particularly required. In addition, since the capacity of the tank is small, it is not appropriate to provide the ultrasonic irradiation means therein. When a hot water storage tank is not used, it is also possible to provide an ultrasonic irradiation means in the flow path. When a hot water storage tank is not used, only about several hundred cc per minute can be passed from the viewpoint of electric capacity in order to heat and raise the temperature of tap water to the appropriate temperature.
Therefore, it is necessary to take measures such as mixing air or performing intermittent water discharge at high speed. When performing this air mixing, if air is mixed, ultrasonic waves will not be propagated,
