[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water cleaning apparatus for cleaning a human buttocks with hot water, and more particularly to a hot water cleaning apparatus having a nozzle cleaning function.

[0002]

2. Description of the Related Art Toilet facilities in which a hot water washing device is installed in a toilet such as a Western style toilet and the buttocks can be washed with hot water after stool or the like are rapidly spreading. This hot water washing apparatus is often provided with a nozzle having a cylinder and a nozzle main body that can protrude from the tip of the cylinder. When hot water is supplied to the rear part of the cylinder, the nozzle body moves forward and protrudes from the cylinder by this water pressure, and hot water spouts from the spout hole at the tip to wash the buttocks. In addition, a hot water cleaning device in which a nozzle body is advanced by a motor is also used.

[0003] In order to wash off dirt adhering to the nozzles of the hot water cleaning apparatus, a system having a mechanism for flowing nozzle cleaning water to the outer surface of the nozzle is widely used. JP-A-11-
Japanese Patent No. 193567 discloses that, when hot water is jetted from a nozzle body and local cleaning is performed, nozzle cleaning water is caused to flow on the outer surface of the nozzle body, so that dirt adhering to the nozzle body is quickly washed down. A hot water cleaning device as described above is described.

[0004]

If the nozzle cleaning water is caused to flow to the outer surface of the nozzle body while the hot water is being jetted from the nozzle body as described above, dirt and the nozzle cleaning water together with the nozzle cleaning water flow into the ejection hole at the tip of the nozzle body. If it reaches, there is a risk that it will be scattered again with the jet water.

[0005] It is an object of the present invention to provide a hot water washing apparatus which prevents such re-scattering of dirt.

[0006]

SUMMARY OF THE INVENTION A hot water cleaning apparatus according to the present invention has a cylinder and a nozzle body protruding from the cylinder, a nozzle for jetting hot water toward a human body, and a nozzle cleaning water on an outer surface of the nozzle body. And a nozzle washing means provided with a nozzle washing means for flowing the nozzle, the nozzle having transmitted the upper surface of the nozzle body from the rear side to the upper surface near the hot water ejection portion at the tip of the nozzle body and on the rear side of the ejection portion. It is characterized in that a ridge or a ridge for guiding the cleaning water to the side of the nozzle body is provided.

In such a hot water washing apparatus, even if dirt accompanies the nozzle washing water flowing on the upper surface of the nozzle body, the nozzle washing water flows down to the side of the nozzle body by the strip. So that the waste does not re-splash with the nozzle jet water.

In one aspect of the present invention, the ridges are provided on both left and right sides of the center of the upper surface of the nozzle body.
The left and right comrades are separated. In this case, a part of the nozzle washing water reaches the ejection part through the space between the strips,
Since the main flow of the nozzle cleaning water flows to the side of the nozzle body along the strip, the dirt also flows to the side of the nozzle body together with the main flow. The nozzle cleaning water that has passed between the strips cleans the vicinity of the spout.

In another aspect of the present invention, the left and right ridges are arranged so as to move away from each other as the tip end side of the nozzle body. By providing the ridges obliquely with respect to the center line of the nozzle main body, water and dirt transmitted from the rear end side of the nozzle main body smoothly flow down to the side of the nozzle main body. Also, it is possible to prevent the waste from remaining along the strip.

[0010]

Embodiments of the present invention will be described below with reference to FIG. FIG. 1A is a perspective view of a nozzle of the hot water cleaning device according to the embodiment, and FIG. 1B is an enlarged view of a tip end portion of the nozzle body.

[0011] The nozzle of this hot water washing device is a cylinder 1
And a nozzle body 2 that can protrude from the tip of the cylinder 1, and a hot water ejection hole 3 is provided on the upper surface of the tip of the nozzle body 2. Further, a knob 4 is provided on the tip end surface of the nozzle main body 2, and the knob 4 can be picked up and the nozzle main body 2 can be pulled out from the cylinder 1. A return spring (not shown) is provided in the cylinder 1 and urges the nozzle body 2 to retreat into the cylinder 1. This nozzle body 2
It is installed diagonally so that the tip side is low.

A feed pipe (not shown) is connected to a hot water introduction port 5 at a rear portion of the cylinder 1, and the feed pipe is connected to a hot water source such as a hot water tank via a switching device (not shown).

When hot water is supplied from the feed pipe to the cylinder 1 by the switching device, the nozzle body 2 moves forward, hot water is blown out from the jet holes 3, and the buttocks of the human body sitting on the Western-style toilet are cleaned.

A port 6 for introducing nozzle cleaning water into the cylinder 1 is provided near the tip of the cylinder 1. The water (warm water or room temperature water) supplied into the port 6 is supplied between the outer peripheral surface of the nozzle body 2 and the inner peripheral surface of the cylinder 1, and the outer periphery of the nozzle body 2 at the tip of the cylinder 1. It flows out from the gap 8 between the nozzle body 2 and the outer peripheral surface of the nozzle body 2.

The water flowing to the outer peripheral surface of the nozzle main body 2 flows along the outer peripheral surface of the nozzle main body 2 to the tip end side of the nozzle main body 2, but the water flowing down the upper surface of the nozzle main body 2 emits water. A protrusion 7 is provided on the upper surface of the nozzle body 2 near the ejection hole 3 in order to prevent the nozzle 3 from reaching the nozzle hole 3.

In this embodiment, two protruding ridges 7 are provided on the left and right sides of the center line of the nozzle body 2 so as to have a substantially C-shape. That is, the ridges 7, 7 approach each other toward the rear end side of the nozzle body 2 and extend away from the front end side of the nozzle body 2. Nozzle body 2 of ridges 7, 7
A predetermined distance (e.g., 0.5 to 2
mm).

In the hot water washing apparatus having the nozzle configured as described above, the nozzle body 2 is advanced and the nozzle washing water is supplied to the port 6 even when the hot water is ejected from the ejection hole 3. Then, water is caused to flow on the outer peripheral surface of the nozzle body 2 to prevent adhesion of dirt. The nozzle cleaning water may be supplied to the port 6 when the nozzle body 2 moves forward or backwards.

When the nozzle body 2 is advanced and hot water is being ejected from the ejection hole 3, the water introduced into the cylinder 1 via the port 6 and flowing out to the outer surface of the nozzle body 2 reaches the ridge 7. Guided by the ridges 7, they flow down to the side of the nozzle body 2, and the water hardly reaches the ejection holes 3.
For this reason, even if dirt accompanies the water flowing along the outer surface of the nozzle main body 2, the dirt is prevented from re-scattering together with the jet water.

Since the ridges 7 extend obliquely to the center line of the upper surface of the nozzle body 2, water flowing along the upper surfaces of the ridges 7 smoothly flows along the ridges 7. It does not flow down to the side and stays along the ridges 7.

Although the ridges 7 are provided in the above embodiment, a ridge may be provided in the same arrangement as the ridges 7 instead of the ridges.

In the above embodiment, the nozzle body 2 is advanced by the water pressure supplied into the cylinder 1, but the nozzle body 2 may be moved forward and backward by a motor. Also,
In the above embodiment, the nozzle cleaning water is supplied into the cylinder 1 and discharged from the gap 8. However, the nozzle cleaning water outlet for discharging the nozzle cleaning water toward the outer surface of the nozzle body 2 is provided on the outer surface of the nozzle body 2. They may be provided close to each other.

[0022]

As described above, according to the present invention, when using the hot water cleaning device, dirt adheres to the nozzle body,
This is prevented from re-scattering with the nozzle jet water. Further, according to the present invention, it is possible to prevent adhesion of dirt to the nozzle body and keep the nozzle body extremely clean.
