Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steam discharge device installed on a wall or the like of a steam bath.

2. Description of the Related Art Conventionally, as shown in FIG. 3, a steam supply port 3 provided on a wall surface 2 of a steam bath 1 so as to face the steam bath 1.
Has a substantially L-shape, and the passage from the inlet 3a to the downward outlet 3b is substantially the same size, or the passage is enlarged toward the outlet 3b.

Problems to be Solved by the Invention In such a conventional configuration, the inlet 3a of the steam supply port 3
Since the passage from the outlet 3b to the outlet 3b has almost the same volume or enlargement, the flow velocity of the steam flowing from the inlet 3a does not decrease. It produced a cut or resonance sound, was extremely noisy, and even gave a sense of danger due to the noise.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the conventional technology, and has as its object to reduce the flow rate of steam and reduce flow noise by performing rectification.

Means for Solving the Problems According to the present invention, which achieves the above object, a narrow path is provided between an inlet and a spout, and gradually narrows toward the spout.

According to the above-described means, the steam flowing from the inlet, which is the pipe connection port, is decelerated in the expansion room, and then the flow velocity is reduced and rectified on the narrow road.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. The discharge port 4 for discharging steam provided on the wall surface 2 of the steam bath 1 is as shown in FIG. That is, the discharge port 4 protrudes from the upper side surface of the inlet 5 also serving as a connection port, has a long-hole or round-hole-shaped steam jet port 6 which opens downward, and has a lower bottom. An expansion room 7 larger than the entrance 5 and a narrow path 8 gradually narrowing toward the steam ejection port 6 are formed in this order. The steam outlet 6 has a straight path 6a at least two to three times the opening width B on the short side in order to obtain noise reduction and rectification. The discharge port 4 is press-fitted into a pipe tube 10 fixed to the wall surface 2 via an annular packing 9 and attached. Or the inlet 5 is the pipe 10
It may be screwed directly to and attached. Reference numeral 11 denotes a steam supply pipe screwed into the pipe tube 10.

In the above embodiment, the steam fed from the steam supply pipe 11 enters the discharge port 4 through the inlet 5 and is discharged from the steam outlet 6 to the steam bathing chamber 1 through the expansion room 7 and the narrow path 8. Then, the flow velocity of the steam suddenly decreases when entering the large-sized room 7 from the inlet 5, the particles constituting the steam collide with each other, and the flow velocity further decreases. Further, since the steam flows from the expansion room 7 to the next narrow path 8 and is focused and rectified, and the steam is discharged while being subjected to the silencing and rectifying action at the steam outlet 6, the discharge sound is extremely reduced.

Effect of the Invention As described above, the present invention can significantly reduce and mitigate the discharge sound of the steam flow spouting from the steam discharge port facing the steam bath, and provide a comfortable steam bath.
