Next, the effects of the drainage path constituting member 5, drainage structure 6, and the like having the above configuration will be explained. The drainage path component 5 constitutes a drainage path from the drain port 1a of the air conditioner 1 to the drain pipe end 4a located above the drain port 1a, and includes a cylindrical main body 7, It includes a first joint 8 to which one end of the main body 7 is connected, and a second joint 9 to which the other end of the main body 7 is connected. Here, the axis of the first joint 8 is approximately L-shaped (in the illustrated embodiment, the direction 8x of the drain side connection port 8a connected to the drain port 1a is connected to the one end side of the main body 7). It is bent so that the direction 8y of the opening 8b on one end of the main body is perpendicular to the direction 8y. In the second joint 9, the direction 9x of the main body other end side connection port 9a to which the other end side of the main body 7 is connected and the direction 9y of the drain pipe side connection port 9b connected to the drain pipe end 4a are as follows. It is possible to selectively change to a parallel posture in which the directions are parallel, and a bent posture in which the directions 9x and 9y are intersecting directions (in the illustrated embodiment, an orthogonal posture in which the directions are orthogonal). In this way, the second joint 9 can be changed between the parallel posture and the bent posture (orthogonal posture), so that the connecting direction of the second joint 9 can be easily changed, and also the parallel posture and the bent posture (orthogonal posture) can be changed. By selecting one of the bent postures (orthogonal postures), it is possible to easily correspond to the situation of the place where the drainage path forming member 5 is arranged.

The first joint 8 is configured by connecting a drain port side member 801 whose shaft center is formed in a substantially L-shape and a first main body side member 802 whose shaft center is formed in a straight shape. The drain port side member 801 can be connected to the first main body side member 802 at any position rotated around the axis of the first main body side member 802. . Therefore, by rotating the drain port side member 801 and changing the direction 8x of the drain port side connection port 8a in the drain port side member 801, the drain port side connection port 8a can be easily connected to the air conditioner. It can be directed toward the drain port 1a of No. 1.

The second joint 9 is configured by connecting a second main body side member 901 and a drain pipe side member 902, and the second main body side member 901 and the drain pipe side member 902 have a protrusion 9d and a recess. By engaging with the portion 9e, it is positioned in the parallel attitude and the bent attitude (in the illustrated embodiment, the orthogonal attitude). A water stop member 9h is interposed between the second main body side member 901 and the drain pipe side member 902, and the water stop member 9h is disengaged from the protrusion 9d and the recess 9e. The drain pipe side member 902 is prevented from moving away from the second main body side member 901 due to its own weight. In this way, by maintaining the engagement between the protruding portion 9d and the recessed portion 9e by the water stop member 9h, the parallel posture or bent posture (orthogonal posture) of the second joint 9 is maintained, and the second joint 9 is assembled. The work (the work of assembling the second main body side member 901 and the drain pipe side member 902, specifically the work of assembling including screwing the second connecting nut 9j into the second male screw portion 9i) is facilitated.

The main body 7 includes a first tubular body 10, a second tubular body 11, and a bent flow path forming member 12 that connects the first tubular body 10 and the second tubular body 11. Therefore, by providing an opening 12j and a lid 12i in the bent flow path forming member 12 located in the middle of the main body 7 (and in turn located in the middle of the drainage path), the inner bent drainage flow path 12a can be inspected. be able to.

A valve body 13 is provided inside the bent flow path forming member 12, and the valve body 13 can be replaced by inserting and removing the valve body 13 from the opening 12j. Furthermore, by providing the valve body 13 at the protruding end of the protruding cylindrical portion 12m that protrudes upward from the bottom plate 12k, impurities such as dust contained in the drainage sink to the bottom plate 12k. It is possible to prevent the valve body 13 from sticking, and the movement of the valve body 13 can be maintained for a long time.

The bent flow path forming member 12 constitutes the apex portion of the drainage path, and includes a first pipe body side connection port 12b to which the first pipe body 10 connected to the drain port 1a of the air conditioner 1 is connected; It has a second pipe side connection port 12c to which the second pipe body 11 connected to the drain pipe end 4a located above the drain port 1a is connected. When the direction 12x of the first pipe body side connection port 12b is vertically downward, the direction 12y of the second pipe body side connection port 12c is horizontal or lower (in the illustrated embodiment, horizontal direction). facing. By using the bent flow path forming member 12 at the apex portion of the drainage path, the orientation of the second tube 11 relative to the first tube 10 can be changed, and bending of the tube itself can be suppressed. Further, the bent flow path forming member 12 includes a fixing portion 12e that can be fixed to the support body 3, and by fixing the fixed portion 12e to the support body 3, the bent flow path forming member 12 itself is supported. .

Therefore, when screwing the connecting nut (the first connecting nut 8d or the second connecting nut 9j) to the male threaded part (the first male threaded part 8c or the second male threaded part 9i), the first connecting body and the second connecting body are screwed together. By rotating the body relatively around the axis of the connection side, both connection ports (the drain side connection port 8a and the connection port 8b on one end of the main body, or the connection port 9a on the other end of the main body) It is possible to change the relative orientation of the drain pipe side connection port 9b) and the drain pipe side connection port 9b), thereby making it possible to easily change the connection direction in this pipe joint.

In addition, the connecting body on the other side (the first main body side member 802 or the second main body side member 901) has a regulation that restricts the movement of the connecting nut (the first connecting nut 8d or the second connecting nut 9j) to the loose side. A convex portion (first regulating convex portion 8g or second regulating convex portion 9n) is provided to avoid unnecessary retreat of the connecting nut (first connecting nut 8d or second connecting nut 9j). Screwing into the male threaded portion (first male threaded portion 8c or second male threaded portion 9i) can be performed quickly. A regulating protrusion (first regulating protrusion 8g or second regulating protrusion 9n) passes through the coupling nut (first coupling nut 8d or second coupling nut 9j) at a predetermined rotational position of the coupling nut. A possible recess (first recess 8h or second recess 9p) is provided, and by moving the connecting nut backward so that the regulating projection passes through the recess, the retaining ring (retaining ring 8j or retaining ring 9r) can be removed. ) can be attached and detached. In addition, in the second connecting nut 9j, by retracting the connecting nut 9j so that the regulating convex portion 9n passes through the recessed portion 9p, the positional relationship between the protruding portion 9d and the recessed portion 9e, which is the positioning means 9c, is adjusted. It can also be visually recognized.

Further, the pipe joint (for example, the second joint 9) includes a first connecting body (second main body side member 901) and a second connecting body (drain pipe side member 902), and the axis of these connecting bodies is Both connection ports (body other end side connection port 9a and drain pipe side connection port 9b) are formed by bending and are rotated relative to each other around the axis of the connection side. The relative orientation of the pipe joint can be changed, thereby easily changing the connection direction in this pipe joint.
