Abstract

PROBLEM TO BE SOLVED: To easily wash out filth by providing a washing nozzle jetting a mixture of water and hot water and an air mixing means mixing air in the mixture of water and hot water to entrain air bubbles. SOLUTION: When washing of the anus is operated, a solenoid valve 28 is opened and water is supplied to a pipe line 27, and water in a water pipe 14 and hot water in a heatexchanger tank 11 are pushed out to a hotwater pipe 16 to supply water and hot water into a conduction mixing valve 15. A feed back control is carried out through a temperature sensor 18. An appropriately hot water whose temperature is adjusted is supplied from a passage-changing over and flow rate-adjusting valve 20 to a hot water feed pipe line 9. Air is forcibly supplied in the hot water feed pipe line 9 from an air pump 21 through a passage-changing over valve 22 and an air pipe line 23 and washing water in which air bubbles are mixed is ejected from a nozzle 7. In this way, by mixing airbubbles with washing water, the fluid ejecting from the washing nozzle has a volume in which the air bubbles are added and hence, the ejecting speed of the washing water is increased. Accordingly, washing excellent in a washing force can be realized even in a small quantity of washing water.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a local cleaning apparatus for cleaning an anus after stool and for cleaning a local part of a woman during a small or menstrual period, and in particular, sprays cleaning water containing bubbles from a nozzle. The present invention relates to a local cleaning device.

[0002]

2. Description of the Related Art FIG. 1 shows a conventional local cleaning apparatus of this type. (For example, Japanese Patent Laid-Open No.
No. 1). FIG. B is a schematic diagram showing a supply system of cleaning water. In FIG. B, reference numeral 1 denotes an electromagnetic valve, and a water supply pipe 2 is connected upstream of the electromagnetic valve, and an instantaneous heating means 3 is connected downstream. Downstream of the heating means 3, a flow control valve 4,
The nozzle device 5 is connected, and the bubble mixing means 6 is connected to the nozzle device 5. With this configuration, the washing water supplied from the water supply pipe 2 reaches the nozzle device 5 via the heating means 3 and the flow control valve 4. Since the bubble mixing means 6 is connected to the nozzle device, bubbles are forcibly mixed into the cleaning water. As a result, the jetting speed of the washing water ejected from the washing nozzle is greatly increased, and the bubbles contained in the washing water expand after the ejection of the washing water, so that the washing water is appropriately diffused and ejected. For this reason, even a small amount of washing water can be used to wash a human body with extremely excellent bodily sensation and detergency. In addition, the instantaneous configuration of the heat exchanger, which can be configured with a normal household power supply, provides significant water savings and energy savings while obtaining clean water at an appropriate temperature even when washing the human body in cold climate conditions. And continuous tapping is possible.

[0003]

However, in the above-mentioned conventional construction, the feeling of cleaning is not sufficient, and the amount of cleaning water is insufficient, and dirt is hardly removed. there were.

In order to control the temperature of the washing water, the amount of electricity supplied to the electric heater must be changed. Therefore, there was a control delay, and the desired temperature could not be discharged immediately.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a mixing means for mixing hot and cold water, a cleaning nozzle for jetting the mixed hot and cold water mixed by the mixing means, and By providing air mixing means for mixing air into the mixed hot and cold water to contain air bubbles, the human body is washed with mixed hot water containing a large amount of air bubbles.

[0006] According to the above invention, since an appropriate temperature is obtained by mixing hot and cold water, the temperature can be easily adjusted, and the appropriate temperature can be discharged immediately. In addition, when the bubble mixing means forcibly mixes bubbles into the washing water, the volume of the fluid ejected from the washing nozzle is substantially the volume of the washing water plus the volume of the bubbles mixed therein, and is ejected from the washing nozzle. The jetting speed of the washing water will be greatly increased. further,
After the flushing of the washing water, the bubbles contained in the flushing water expand, so that the flushing water is appropriately diffused and ejected. Therefore, even if the amount of the washing water is small, the momentum and the diffusion range of the washing water can be set to appropriate values for washing the human body. In other words, it is possible to clean a human body with very good bodily sensation and detergency even with a small amount of washing water. Furthermore, since the human body was washed with a small amount of washing water and mixed with hot and cold water, a sufficient boiling capacity was obtained even with an instantaneous configuration in which the heat exchanger could be configured with a normal household power supply. It is possible to obtain washing water at an appropriate temperature and an appropriate flow rate even in washing a human body in cold district conditions. As a result, it is possible to save a large amount of water, to achieve a great energy saving accompanying it, and to perform a comfortable washing without running out of hot water even if a sufficient amount of washing water is used.
