Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a steam ejector for ejecting high-temperature steam into a sauna chamber in a steam sauna.

(Prior Art) Conventionally, as a steam ejector installed in a sauna room of a steam sauna, a structure shown in FIG. 3 shown in Japanese Utility Model Publication No. 62-72694 is known. The structure will be described below. 1 is a steam carrier pipe, 2 is a steam ejection nozzle, 3 is a heat insulating cover, and 4 is packing. The steam carrier pipe 1 is embedded in the side wall 5, and a tile wall 6 which is a covering material is provided on the indoor side of the side wall 5.
Is installed. In the steam ejector having the above structure, the steam is ejected from the steam ejecting nozzle 2 into the room through the steam carrier pipe 1, and the heat insulating cover 3 is contacted by the bather to the vapor ejecting nozzle 2 heated to a high temperature by the steam. To prevent burns.

(Problems to be solved by the invention) However, in the above-mentioned conventional example, the side walls 5 and the tile walls 6 become high in temperature due to heat transfer from the steam pipes such as the steam carrier pipe 1 and the steam jet nozzle 2 which have become high in temperature. The side wall 5 and the wall material of the tile wall 6 may be thermally deteriorated, and a bather may touch the tile wall 6 and feel very hot or get burned.

The present invention was devised in view of such circumstances, and an object thereof is to protect the wall material from thermal deterioration even during long-term operation, and to guarantee the safety for bathers. It is what

(Means for Solving the Problems) In order to achieve the above object, in a steam ejector according to the present invention, a steam ejector attached to a side wall of a sauna chamber for ejecting steam supplied from a steam carrier pipe into the sauna chamber In the container, a tubular adapter and a steam introduction pipe, both of which have a flange portion on the proximal end side, a back cover and an exterior cover that form a flow space of the steam flowing from the steam introduction pipe, and a jet port provided in the exterior cover The adapter has a tip portion inserted into the opening formed in the side wall, and the steam introduction pipe is a member for inserting the tip portion into the adapter and connecting the steam carrier pipe to the tip portion. Has both flanges fixed to the side wall, and at least one of the adapter and the steam introducing pipe has a structure in which the outer diameter of its tip end is reduced as compared with the base of the insertion portion.

(Operation) In the above configuration, the steam sent from the steam carrier pipe flows from the steam introduction pipe into the flow space formed between the back cover and the outer cover, and is ejected into the room from the ejection port provided in the outer cover.

An adapter is interposed between the steam introducing pipe and the opening formed in the side wall, and an air heat insulating layer is interposed between the opening and the adapter and between the adapter and the steam introducing pipe.
The heat conduction from the steam introduction pipe to the side wall is weak.

(Embodiment) An embodiment of the present invention will be specifically described below with reference to FIGS. 1 and 2.

Reference numeral 11 denotes a side wall panel of the sauna room, and an opening 12 is formed at a predetermined position of the side wall panel 11. 13 is an adapter molded of heat-resistant synthetic resin, the adapter 13 is a cylindrical shape with both ends open, a flange 13a and a protrusion 13b are integrally formed on the base end side, and compared with the base of the insertion part into the opening 12. Then, the outer diameter of the tip side is reduced. Reference numeral 14 is a brass vapor introducing pipe, which has a flange portion 14a integrally formed on the base end side, and the outer diameter on the tip end side thereof is reduced as compared with the base portion of the insertion portion into the adapter 13. Reference numeral 15 is a packing, 16 is an annular bush made of heat-resistant synthetic resin, and a tubular portion 16a integrally formed with the bush 16 is fitted into an opening provided in a flange portion 14a of the steam introducing pipe 14. 17 is a wood screw. Reference numeral 18 denotes a steam pipe inserted into the steam introduction pipe 14 from the base end side, and the steam introduction pipe 14 and the steam pipe 18 are sealed by an O-ring 19. 20
Is a back cover, 21 is an exterior cover, a steam circulation space 22 is formed between the covers 20 and 21, and on both sides of the exterior cover 21 except a portion facing the steam outlet 18a of the steam pipe 18. A slit-shaped steam outlet 23 is opened. The outer cover 21 has a peripheral wall portion 21a formed around it, and a plurality of openings 21b are provided at the tip of the peripheral wall portion 21a. 24 is a spacer and 25 is a washer.

In the above structure, the procedure for attaching the steam ejector will be described. First, insert the tip of the adapter 13 into the opening 12
13a is brought into contact with the inner surface of the side wall panel 11 via the packing 15. Next, the steam introducing pipe 14 is inserted into the adapter 13, and pushed in until the flange portion 14a comes into contact with the protruding portion 13b, the bush 16 is fitted to the flange portion 14a, and the adapter is screwed with the wood screw 17.
13 and the steam introducing pipe 14 are fixed to the wall panel 11. Then, the steam pipe 18, the back cover 20, the outer cover 21, and the spacer 24 are bonded and integrated in advance, the steam pipe 18 is inserted into the steam introduction pipe 14, and the outer peripheral portion of the outer cover 21 is washer 25.
It is fixed to the side wall panel 11 with wood screws 17 sandwiching,
A steam carrier pipe 26 connected to a steam generator is connected to the tip of the steam introducing pipe 14.

The steam flows into the circulation space 22 through the steam introduction pipe 14 and the steam pipe 18, and is ejected into the room from the slit-shaped ejection port 23 provided in the exterior cover 21. Due to such flow of steam, the temperature of the steam introducing pipe 14 becomes particularly high, and since it is made of metal because it is connected to the steam carrying pipe at the tip side, heat transfer to the surroundings is remarkable. However, in the above configuration, the side wall panel
A heat insulating adapter 13 is interposed between 11 and the steam introducing pipe 14, and a gap 26 is provided between the opening end 12 formed in the side wall panel 11 and the adapter 13, and between the adapter 13 and the steam introducing pipe 14. Also, the void 27 is formed, and the voids 26, 27 become a heat insulating space, and the heat insulating action of the adapter 13 is also added, so that the heat transfer amount from the steam introducing pipe 14 to the side wall panel 11 is reduced as much as possible. Of.

(Effects of the Invention) As described above, according to the steam ejector of the present invention,
Since heat conduction from the steam pipe to the mounting wall is weakened by interposing the heat insulating space, the wall material can be protected from thermal deterioration for a long period of time.

Further, because the heat insulating space is formed, no special device is required for its mounting work, which is advantageous in that the steam ejector can be easily mounted.
