DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a sanitary cleaning device that uses cleansing water to clean private parts after defecation.Prior Art This type of sanitary cleaning device has For example, JP-A-60-1
As shown in Japanese Patent No. 6628, the structure was as shown in FIG.

That is, the main body 1 is installed on a toilet bowl 2, and inside the main body 1, there are a pump 3, a hot water tank 4, and a nozzle 6 as a water supply device. 6. 7. 8 is a hose.

A heater 9 and a water supply vibrator 1o are provided in the hot water tank 4.

Since the hot water tank 4 requires a large capacity, it is installed at the end of the main body 1 away from the toilet bowl 2, and the nozzle 6 is connected to the toilet seat (located on the toilet bowl 2) in order to accurately clean the private parts of the human body. (not shown) is provided within the main body approximately on the center line.

Problems to be Solved by the Invention However, with such a structure, the distance between the hot water tank 4 and the nozzle 6 is large, so the hose 8 that connects the hot water tank 4 and the nozzle 5 becomes long, and the inside of the hose 8 becomes long. There was a problem that residual water remained on the skin and cold water hit the private parts at the beginning of cleaning.

This is due to the following reason.

The hot water tank 4 is provided on a shaft portion of the main body 1 that is located above the toilet bowl 2 because it is necessary to have a tank capacity as large as possible so that water can be washed at a constant and stable temperature during washing. Further, the nozzle 6 is provided within the main body approximately on the center line of a toilet seat (not shown) placed on the toilet bowl 2 in order to ensure that the cleansing water hits the private parts accurately during cleansing.

A pump 3, which is a water supply device, pressurizes water sucked in from the outside and sends the water into a hot water tank 4. Inside the hot water tank 4, hot water is stored by a heater 9, and when water is supplied, Washing water passes through the hose 8 and is jetted out from the spouting hole of the nozzle 6, so that private parts can be washed.

However, by the time the next person uses the water, the remaining water in the hose 8 cools down and becomes cold water.In this configuration, the hot water tank 4 and nozzle 5 are separated, so the hot water tank 4 and nozzle 5 must be connected. Since the hose 8 is long, there is a large amount of remaining water.

As a result, there was a problem in that cold water hit private parts at the start of cleaning.

Therefore, the present invention reduces the amount of residual water by shortening the hose connecting the hot water tank and the nozzle.

Means for solving the problems and technical means of the present invention for solving the above problems are as follows:
A part of the upper part of the hot water tank is extended toward the nozzle side, and a water channel communicating with the nozzle is provided in this projecting part.

action The effect of this technical means is as follows.

That is, by extending a part of the upper part of the hot water tank toward the nozzle side and providing a waterway communicating with the nozzle in this projecting part, the distance between the hot water tank and the nozzle is brought closer, and the connection between the two is shortened. Reduce the amount of remaining water during that time.

As a result, cold water is less likely to hit your buttocks in the early stages of cleaning.
Allows for comfortable cleaning.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In FIG. 2, the main body 11 is placed on a toilet bowl 12, 13 is a toilet seat, and 14 is a toilet lid.

15 is a power switch, and 16 is a water pressure adjustment knob for washing.

FIG. 1 shows the internal structure of the main body 11. Reference numeral 017 represents a case, and 18 represents a back plate, which are integrally formed with a hot water tank 19. 2o is a pump, 21 is a motor that drives the pump, and 22 is a nozzle. The hot water tank 19 has a sealed structure with a flange 23. Inside the hot water tank 19,
A sheathed heater 24 water supply pipe 26 is provided approximately in the center of the hot water tank 19 so as to supply water toward the bottom. 26 is a stopcock for draining water. The hot water tank 19 has a main body part 27 and an overhang part 28 extending from the upper part to the nozzle 22 side.
There are nine exit holes 29. The hot water tank 19 and the nozzle 22 are communicated and connected by a hose 3o.

FIG. 3 is a cross-sectional view of the nozzle 22, in which 31 is a cylinder;
2 is a nozzle body, 33 is a nozzle body pressure receiving part, 34 is a spring, 35 is a guide part that regulates the rotation and sliding of the nozzle body 32, 36 is a water supply part, and 37, 38, and 39 are packings for water sealing. be. 40 is a water passage provided in the nozzle body 32, and 41 is an ejection hole.

Next, the operation of the configuration of this embodiment will be explained.

Normally, the power switch 16 is turned on, and the hot water in the hot water tank 19 and the toilet seat 13 are controlled by a temperature control device (not shown).
The temperature is at an appropriate temperature. Main body part 27 of hot water tank 19
A sheathed heater 24 is provided near the bottom of the tank, and not only the main body part 27 but also the projecting part 28 become hot water by convection of hot water, and hot water at a constant temperature is stored in the hot water tank 19.

When cleaning the private parts after excretion, turning the water pressure control knob 1 causes the motor 21 to rotate the ONL pump 20, sucks water from a tank (not shown) outside the main body 11, pressurizes it, and pumps it into the hot water tank. Cleaning water is sent to 19. Water supply pipe 2
6, the wash water is supplied toward the bottom of the main body portion 27 of the hot water tank 19, pushing up the stored hot water.

The hot water is in the main part 27. Overhanging portion 28. It is supplied to the nozzle 22 through a hose 30.

In FIG. 3, when cleaning water is supplied to the water supply section 36,
The nozzle body 32 projects out of the cylinder 31 against the spring 34 due to water pressure, with its rotation and sliding being regulated by the guide portion 25. At this time, cleaning water leaks from the gap provided between the cylinder 31 and the pressure receiving part 33 of the nozzle body 32 and cleans the nozzle body 32 and the ejection hole 41.

When the nozzle body 32 protrudes and the QIJ ring 38 attached to the nozzle body 32 comes into contact with the guide part 36, the internal pressure of the cylinder 31 increases, and the cleaning water passes through the water passage 4o and is jetted out from the spout hole 41. You can wash your private parts.

As a result, since the hot water tank 19 is provided with the projecting portion 28 and the outlet is provided on the nozzle 22 side, the hot water tank 19
The distance between the nozzle 22 and the hose 30 can be shortened, and residual water can be reduced. Since there is little residual water, when the nozzle body 32 protrudes, this residual water comes out from the gap between the cylinder 31 and the pressure receiving part 33 of the nozzle body 32, and when the nozzle body 32 protrudes and the cleaning water hits the private parts, hot water is released. is ejected from the ejection hole 41, allowing for comfortable cleaning.

In addition, since the hot water tank 19 and the back plate 18 are integrally formed, it becomes a box structure, which increases the strength, and reduces costs by making it a single part instead of the conventional two parts of the hot water tank 19 and the back plate 18. becomes.

Further, in this configuration, the water supply pipe 25 supplies cleaning water toward the bottom of the main body part 27 of the hot water tank 19 to push up the stored hot water, and furthermore, Since the overhang 28 is provided on the nozzle 22 side and the outlet of the hot water tank 19 is provided on the nozzle 22 side, the overhang 28 acts as a guide for the flow of hot water, and the hot water and the supplied water are mixed together. The temperature of the washing water no longer changes or drops, improving hot water dispensing performance (the ability to continuously dispense hot water at a constant temperature).

However, in this configuration, by providing the overhang portion 28, the capacity of the hot water tank increases, so the amount of hot water stored increases and the hot water tapping performance improves.

Figure 4 shows the above-mentioned hot water tapping performance, where the horizontal axis is time;
The vertical axis indicates the temperature of the cleaning water jetted from the nozzle.

M is the hot water dispensing performance of the conventional sanitary cleaning device, B is the hot water dispensing performance of the sanitary cleaning device of the present invention with the same tank capacity as the conventional one and provided with an overhang, and G is the hot water dispensing performance of the sanitary cleaning device of the present invention. By implementing this, hot water tapping performance can be significantly improved.

Next, other embodiments of the present invention will be described.

FIG. 5 shows another embodiment in which the overhang 28' extends to the nozzle 22' and the overhang 28' extends to the nozzle 22'.
By providing a nozzle 22' inside the container, residual water will not drain out. Furthermore, the capacity of the hot water tank 19' can also be increased.
