JPH09144106A - Washing nozzle for human body part washing device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a stable, wash water jetting angle when a washing nozzle provided with a water-way space inside and wash water jetting ports is manufactured, by providing a wall part in the water-way space close to the upstream side or the downstream side of the jetting ports to change the flow direction of the wash water. SOLUTION: A wall part 17 is provided in a cylinder space 14 formed inside a nozzle and close to the position, at which jetting ports 15, 16 cross the axial direction of the nozzle, on the upstream side or the downstream side of the jetting port 15 of the washing nozzle 13 having the wash water jetting ports 15, 16 connecting the cylinder space 14 to the outside. The wash water flowing in the cylinder space 14 strikes the wall part 17 on the upstream side to turn downward and to flow in the direction of the jetting port 15. The wash water striked the wall part 17 provided on the downstream side, strikes the bottom face of the cylinder space 14 to change the flow direction and to flow in the direction of the jetting port 16 so that the water intake angle may be brought near a set jetting angle. Thus, a stable jetting angle of the wash water can be obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning nozzle for a human body local cleaning device.

[0002]

2. Description of the Related Art A conventional technique of this type (see, for example, Japanese Patent Laid-Open No. Sho 62-62).
The washing nozzle of JP-A-68937) has spouts 100 and 101 through which washing water is spouted as shown in FIG. 4, but the washing is performed especially at the spout 100 depending on the angle of the spout. There was a problem that the direction of water flow could not be sufficiently changed, and even if the set angle was the angle shown by the broken line, it was actually the angle shown by the solid line, and it was difficult to obtain the jet angle as set. For this reason, the ejection angle becomes unstable, which causes variation.

[0003]

SUMMARY OF THE INVENTION It is a technical object of the present invention to provide a cleaning nozzle for a human body local cleaning device capable of obtaining a jet angle as set.

[0004]

[Means for Solving the Problems] The technical means taken to solve the above-mentioned technical problems include a water channel space formed inside and an outlet for washing water which communicates the water channel space with the outside. The cleaning nozzle of the human body local area cleaning device has a wall portion that is provided in the water channel space and that is located near the upstream side or the downstream side of the ejection port.

In the present invention having the above-mentioned structure, since the washing water flowing in the cylinder space can hit the wall portion and sufficiently change the direction of the flow, the direction of the flow in the vicinity of the jet port approaches the jet angle. It is possible to obtain a stable jetting angle of wash water as set.

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a view showing a state in which a human body local cleaning apparatus is used, and FIG. 2 is a sectional view of an embodiment of a cleaning nozzle tip portion. In the figure, the human body local cleaning device 10 is a toilet
The cleaning nozzle 13 is attached to the back of the cleaning nozzle 1 (on the right side in FIG. 1).

The cleaning nozzle 13 has a cylinder space 14 and
A jet port 15 that communicates the cylinder space 14 with the outside,
16 and. A wall portion 17 is provided in the cylinder space 14 in the vicinity of the upstream side of the ejection port 15 so as to further overlap at least the ejection port 15 in the axial direction.

FIG. 3 is a sectional view of the tip portion of the cleaning nozzle according to another embodiment of the present invention. In this other embodiment, the wall portion 17 is provided near the downstream side of the ejection port 15.

In the embodiment shown in FIG. 2, the cylinder space 1
By flowing the wash water flowing in 4 around the wall portion 17, it is possible to make the water entry angle to the ejection port 15 close to the ejection angle, and to obtain the ejection angle as set.

In another embodiment shown in FIG. 3, the wash water collides with the wall portion 17 and is jetted in a state where the flow direction is sufficiently changed, so that the jet angle can be obtained as set.

Since the jet outlets 16 of both embodiments collide with the bottom surface of the cylinder space 14 and the direction is changed, the jetting angle as set can be obtained.

In the above-described embodiment, the washing water flowing in the cylinder space 14 can hit the wall portion 17 to sufficiently change the direction of the flow, and the jetting angle of the washing water can be made stable as set. Since it can be obtained, it is possible to prevent the ejection angle from varying for each product.

[0014]

According to the present invention, since the cleaning water flowing in the cylinder space can hit the wall portion and sufficiently change the direction of the flow, the direction of the flow in the vicinity of the ejection port should be close to the ejection angle. It is possible to obtain a stable jet angle of washing water as set. Therefore, it is possible to prevent the ejection angle from varying for each product.
