Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a private parts cleaning device for cleaning private parts after defecating.

Generally, the temperature of hot water jetted from the cleaning nozzle of the private parts cleaning device installed near the toilet seat to clean the private parts such as the anus after defecation is 32 to 42 degrees Celsius, and the amount of water is 450 to 50 degrees Celsius.
c/min is said to be appropriate.

However, the temperature of tap water can drop below 10 degrees Celsius or close to 0 degrees Celsius in winter, and if you try to raise the water to the appropriate temperature, the power of the heater will exceed 1KW, which is not suitable for ordinary household electrical appliances. This is undesirable, and if you try to forcefully install it, you will need special wiring and electrical outlet equipment work.

Therefore, conventional private parts cleaning devices store heat in some way to reduce power consumption to 1KW or less, allowing them to be used as general household appliances, but they require equipment such as a hot water storage tank to store heat, making the device large. In addition, when the hot water tank is not used for a long time, heat is dissipated from the hot water tank, and electric power must be supplied to compensate for the heat, which increases the amount of electric power consumed.

In general, the factors that affect the cleaning effect of such a private area cleaning device include a cleaning water temperature, b cleaning water jetting angle, c cleaning water jetting speed, and d cleaning water jetting water amount. If it exceeds 40°C, it may feel hot, so a temperature of 40°C or less is desirable, and if it is below 35°C, it may feel cold, so 36 to 40°C is the appropriate temperature.

(b) Considering the nozzle mounting position, splashing of cleaning water, etc., it is safe to set the spray angle upward by about 30 degrees from the rear to the front.

(c) The faster the spray speed, the better the cleaning effect, but if it is too fast, you will feel pain in the local area and there will be more scattering to the surrounding area, so there is a limit to the speed.

dThe greater the amount of water sprayed, the better the cleaning effect, but there is a limit to the amount of water due to equipment capacity.

Taking these into consideration, it can be said that it is appropriate to inject water at a rate of 450 to 500 cc/min from an injection nozzle with an inner diameter of about 1.5 mm.

However, under such water volume conditions, a heat storage means such as a hot water storage tank is required as described above.

The present invention has been made in view of these points,
It is an object of the present invention to provide a private part cleaning device that can suppress the power consumption of a heating device to 1 KW or less without reducing the cleaning effect and without requiring a heat storage means.

This invention was made based on the discovery as a result of various studies that the above-mentioned cleaning effect can be obtained even with a small amount of washing water by mixing air in the form of bubbles into hot water for private washing. The method is to form an air suction section near the cleaning water injection nozzle for mixing air into the hot water introduced from the heating device.

The present invention will be explained below based on embodiments shown in the drawings.
As shown in the flowchart in Figure 1, water flows from a water pipe 1 through a water stop valve 2, a strainer 3, a backflow prevention valve 4, a solenoid valve 5, a water flow control valve 6, a heating device 7, and a vacuum breaker valve 8. It will be sprayed locally from the spray nozzle 9.

This flowchart shows the general flow,
In reality, the heating device 7 is provided with necessary safety devices in addition to an automatic temperature controller.

Figure 2 shows a cross section of the nozzle 9, and the toilet main body 10.
The main nozzle 9 located at the rear of the toilet seat 11 is located at the bottom of the toilet seat 11.
Consists of a nozzle 12 and a nozzle body 15, with an inner diameter of 1 m.
The hot water injected from the first nozzle 12 with a diameter of approximately 1.5 m passes through a rounded cavity 16 provided in the nozzle body 15, and the direction of the water flow is bent by approximately 90 degrees midway through, and is injected from the injection port 13 toward the local area. Since the air suction port 14 is provided near the injection port 17 of the first nozzle 12, the hot water sucks air and the hot water mixed with bubbles flows through the injection port with a diameter of 2 to 2.5 mm. 13 will be injected.

The diameter of this injection port 13 is slightly larger than that of conventional private parts cleaning devices, so the injection speed is moderate, and although the amount of water is slightly small, the cleaning effect is large because air bubbles are mixed in. .

Also, since air bubbles are mixed in, there is no local pain, and no water droplets are scattered around the area.

According to the experimental results, in the case of hot water of 36-40℃, the temperature is 350-4
00cc/min water flow compared to conventional 450~500cc/min
Therefore, according to the present invention, by sucking air into the jetted hot water for private parts washing, the water volume is 350 to 400C.
C/min, and can be sufficiently heated with a heating device of 1KW or less, which is the maximum capacity of general household appliances and indoor wiring equipment, without installing a heat storage means such as a hot water storage tank.
The water temperature can be raised by 37 degrees Celsius, and even when the tap water temperature drops to 5 degrees Celsius or less in cold weather, private parts can be comfortably washed with warm water at an appropriate temperature.It saves water and power, and also simplifies the device. This has advantages such as miniaturization.
