Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in a structure in which two spouts attached to a bathtub are joined together by pipes. The ejector ejects the circulating hot water together with the bubbles into the bath.

[0002]

[Prior art]

 Conventionally, as for the piping structure of a bubble bath, as shown in FIGS. 2 (A) and 2 (B), pipe joints 3 and 4 such as elbows are joined to the adjacent jetting tools 2 and 2 provided in the bath 1 to form pipe joints. One of the flexible hot water supply pipes 5 extending in a straight line is brazed to each of the joining ports 3a and 4a of the braids 3 and 4 and brazed to each other. Further, the ejection tools 2 and 2 are joined to the pipe joints 7 and 8 such as elbows, and one of the flexible air supply pipes 9 linearly extended to the joint ports 7a and 8a of the pipe joints 7 and 8. The ends of the pipes are brazed and 6-joined. Although not shown, the hot water supply pipe 5 and the air supply pipe 9 are flared at the pipe ends cut to a length suitable for the construction site, and the pipe ends are connected to the pipe joints 3, 4 or 7, 8 with flare nuts. Sometimes joined.

The jetting device 2 includes a casing 2a, a jetting port 2b facing the bath 1 and a nozzle 2c provided in the casing 2a, and a water channel 2d communicating with the jetting port 2b in the casing 2a. Are formed. The hot water supply pipe 5 is joined to a suction tool (not shown) provided in the bathtub 1, and a circulation pump (not shown) is arranged in the middle thereof. When the hot water in the bathtub 1 is supplied through the hot water supply pipe 5 when the circulating pump is started, each of the ejection tools 2 mixes the air sucked from the air supply pipe 9 as air bubbles when ejecting from the nozzle 2c. The circulating hot water is ejected together with the bubbles from the ejection port 2b.

[0004]

[Problems to be solved by the device]

 However, joining the hot water supply pipe 5 and the air supply pipe 9 with the brazing 6 requires a high degree of skill and has a problem that the construction time becomes long. Furthermore, joining the hot water supply pipe 5 and the air supply pipe 9 by performing flare processing on site requires a high degree of skill as well as a problem that the construction time becomes long, and a male screw that is a partner of the flare nut is used. There is a problem that a special pipe joint is required.

In order to solve the above-mentioned problems, an object of the present invention is to provide a pipe joining structure for a jetting tool in a bubble bath which can be installed in a short time without requiring a high degree of skill.

[0006]

[Means for Solving the Problems]

 Means adopted by the present invention is a structure in which the joint ports of two ejectors attached to a bathtub are joined together by joint pipes, in which annular groove portions are formed on the outer peripheries of both pipe ends of the joint pipes, respectively. An annular packing is fitted in the groove, and corresponding pipe ends of the joint pipes are watertightly inserted into the joint ports of the two ejectors, and the joint of the ejector in the bubble bath is joined. It is a structure.

[0007]

[Action]

 By simply inserting the corresponding pipe ends of the joint pipes into the joints of the two ejectors in a watertight manner, the joints of the ejectors can be joined to each other by piping.

【Example】

 Hereinafter, a piping structure of a bubble bath according to the present invention (hereinafter, referred to as "the piping structure of the present invention") will be described based on an embodiment shown in the drawings. 1 (A) and 1 (B) show an embodiment of the piping structure of the present invention. FIG. 1 (A) is a partially sectional plan view, and FIG. 1 (B) is a front view looking straight from the outside of the bathtub. In this embodiment, the piping structure of the present invention is applied to the joining of the hot water supply pipe 15 and the air supply pipe 19.

The joint structure of the hot water supply pipe 15 is as follows. The hot water supply pipe 15, which is a joining pipe, is formed of a copper pipe or the like, and a flexible portion 15b such as a bellows is formed in the middle thereof so that it can be easily bent and the like. It is designed to handle the error. The hot water supply pipe 15 has one or a plurality of annular groove portions 15a formed by plastic working or the like on the outer circumferences of both pipe ends. An annular packing 20 made of an O-ring or the like is fitted in each annular groove 15a. Pipe joints 13 and 14 such as elbows are joined to the ejection tools 2 and 2. The ejection pipe 2 may be integrally formed with the pipe joint 13 or 14. The pipe joints 13 and 14 are formed with joint ports 13a and 14a into which the pipe ends of the hot water supply pipe 15 can be watertightly inserted through the annular packing 20.

The hot water supply pipe 15 is joined to the pipe joints 13 and 14 by first inserting one end of the hot water supply pipe 15 into the connection port 13a (14a) of the one pipe joint 13 (or 14) and then inserting it. One of the pipe ends is pulled back and the other pipe end is inserted into the connection port 14a (13a) of the other pipe joint 14 (or 13). Finally, in the hot water supply pipe 15, a connector 21 such as a quick washer is fitted to one pipe end and the pipe joint 13 (or 14) so as not to move in the insertion direction.

The hot water supply pipe 15 is joined to the pipe joints 13 and 14 by inserting both ends of the hot water supply pipe 15 into the connection ports 13a (14a) of the pipe joints 13 and 14, respectively. 2 may be attached to the bathtub 1.

The joint structure of the air supply pipe 19 is as follows. The air supply pipe 19 which is a joining pipe is formed of a copper pipe or the like, and a flexible portion 19b such as a bellows portion or a curved portion (not shown) is formed in the middle thereof so that the air supply pipe 19 can be easily curved. It has become possible to deal with the error in the mounting position of the ejection tools 2 and 2. The air supply pipe 19 has one or a plurality of annular groove portions 19a formed on the outer circumferences of both pipe ends by plastic working or the like. An annular packing 26 made of an O-ring or the like is fitted in each annular groove 19a. Pipe joints 23 and 24 such as elbows are joined to the ejection tools 2 and 2. The ejection pipe 2 may be integrally formed with the pipe joint 23 or 24. The pipe joints 23, 24 are formed with joint ports 23a, 24a into which the pipe ends of the air supply pipe 19 can be watertightly inserted via an annular packing 26.

The air supply pipe 19 is joined to the pipe joints 23 and 24 after the one end of the air supply pipe 19 is excessively inserted into the connection port 23a (or 24a) of the one pipe joint 23 (or 24). , One inserted pipe end is pulled back, and the other pipe end is inserted into the connection port 24a (or 23a) of the other pipe joint 24 (or 23). Finally, the air supply pipe 19 is fitted with a connector 27 such as a quick washer on one pipe end and the pipe joint 23 (or 24) so as not to move in the insertion direction.

The hot water supply pipe 19 is joined to the pipe joints 23 and 24 by inserting both pipe ends of the hot water supply pipe 19 into the connection openings 23a (24a) of the pipe joints 23 and 24, respectively. 2 may be attached to the bathtub 1.

In the present embodiment, by simply inserting the pipe end of the hot water supply pipe 15 into the joint opening connection ports 13a and 14a of the two ejectors 2 and 2 in a watertight manner, the joint ports of the ejectors 2 and 2 can be quickly and simply formed. The pipes 13a and 14a can be simply and quickly joined together. Further, in this embodiment, by simply inserting the pipe end of the air supply pipe 19 into the joint openings 23a and 24a of the two ejectors 2 and 2 in a watertight manner, the joint 23a of the ejectors 2 and 2 can be quickly and simply formed. , 24a can be simply and quickly pipe-joined.
