The object of this invention is to provide a pipe joint and cover member connection structure and a pipe joint device that prevents the cover member from falling off due to its own weight when the cover member is provided to cover the pipe joint (connection member).

In order to achieve the above object, the pipe joint and covering member connecting structure and pipe joint device according to the present invention have the following configuration.
The connection structure between a pipe joint and a covering member according to the invention of claim 1 is a connection structure between a pipe joint having a connection port with a pipe body, and a covering member that covers the pipe joint so as to accommodate the pipe joint inside. The covering member has one or more divided parts extending along its axial direction, and can cover the pipe joint so as to accommodate the pipe joint inside by closing the divided parts. Here, a coupled part is formed on the outer surface of the pipe joint. A coupling part that couples with the coupled part is formed on the inner surface of the covering member. The pipe joint has a bent part where the axis is bent, and the coupled part is formed on the outer surface of the bent part of the pipe joint, on the side away from a cross section cut by a plane including the axis of the bent part. The covering member has a bent part where the axis is bent, and the coupling part is formed on the inner surface of the bent part of the covering member, on the side away from a cross section cut by a plane including the axis of the bent part. Therefore, the joinable part and the joining part are in a joining relationship with each other, with a convex part and a concave part that fits into the convex part and joins to the convex part by friction, and this joining temporarily holds the covering member in place on the pipe joint so that it does not fall off due to its own weight.

The connecting structure between a pipe joint and a covering member according to the invention of claim 2 is a connecting structure between a pipe joint having a connection port with a pipe body and a covering member that covers the pipe joint so as to accommodate the pipe joint inside. The covering member has a plurality of division parts extending along its axial direction, and is provided with a plurality of divided bodies divided by the division parts, and can cover the pipe joint so as to accommodate the pipe joint inside by closing the division parts. Here, the pipe joint has a coupled part formed on its outer surface. The covering member has a coupling part formed on its inner surface that couples with the coupled part. At this time, the coupling part is formed on each divided body of the covering member, and the pipe joint has the coupled part formed corresponding to the coupling part of each divided body. Here, the coupled part and the coupling part are in a coupling relationship between a convex part and a concave part that fits into the convex part and couples with the convex part by friction, and due to this coupling, each divided body of the covering member is temporarily held by the pipe joint so as not to fall by its own weight.
In addition, the connection structure between a pipe fitting and a covering member according to the invention recited in claim 3 is the connection structure recited in claim 2 , wherein the joined portions are formed on both sides away from a cross section cut by a plane including the axis of the pipe fitting, and the connecting portions are formed on both sides away from a cross section cut by a plane including the axis of the covering member .
The invention of claim 4 relates to a connection structure between a pipe joint and a covering member, which is a connection structure between a pipe joint having a connection port with a pipe body, and a covering member that covers the pipe joint so as to accommodate it inside. The covering member has one divided portion extending along its axial direction, and by closing the divided portion, it is possible to cover the pipe joint so as to accommodate it inside. Here, the pipe joint has a coupled portion formed on its outer surface. The covering member has a coupling portion formed on its inner surface that couples with the coupled portion. The coupled portion and the coupling portion are in a coupling relationship between a convex portion and a concave portion that fits into the convex portion and couples with the convex portion by friction, and due to this coupling, the covering member is temporarily held on the pipe joint so as not to fall off due to its own weight, even if the divided portion is not closed.

A pipe joint device according to the invention of claim 5 includes a pipe joint having connection ports for connecting to a pipe body at both ends and having an axis bent in an approximately L-shape, and a cover member for covering the pipe joint so as to accommodate it therein. The cover member has a cylindrical shape with an axis bent in an approximately L-shape, and has one or more divided parts extending along the axis direction, and can cover the pipe joint so as to accommodate it therein by closing the divided parts. Here, a coupled part is formed on the outer surface of the pipe joint. This coupled part is formed on the outer surface of the bent part of the pipe joint where the axis is bent in an approximately L-shape, on the side away from a cross section cut by a plane including the axis of the bent part. The cover member has a coupling part formed on its inner surface for coupling with the coupled part, and the coupling part is coupled to the coupled part, so that the cover member is temporarily held on the pipe joint so as not to fall under its own weight.

A pipe joint device according to the invention of claim 6 includes a pipe joint having connection ports for connecting to pipes at both ends, and a cover member for housing the pipe joint therein. The pipe joint includes a first connecting body and a second connecting body, each having the connection port at one end, and the other ends of the first connecting body and the second connecting body are connected to each other. The first connecting body and the second connecting body are both formed with a bent axis, and the first connecting body and the second connecting body are connected at rotational positions rotated relatively around the axis of the connecting side, thereby making it possible to change the relative orientation of the connection port. On the other hand, the covering member is composed of a first cylindrical covering body with a curved axis that covers the first connecting body so as to accommodate it therein, and a second cylindrical covering body with a curved axis that covers the second connecting body so as to accommodate it therein, and each covering body has one or more divided parts extending along its axial direction, and by closing the divided parts, it is possible to cover the first connecting body and the second connecting body so as to accommodate them therein. In addition, a coupled part is formed on the outer surface of one of the first connecting body and the second connecting body. Then, a coupling part that couples with the coupled part is formed on the inner surface of the covering body that covers the one connecting body of the first covering body and the second covering body, and the covering body that covers the one connecting body is temporarily held on the one connecting body by the coupling part and the coupling part so that it does not fall under its own weight.

The pipe joint in this pipe joint device has a first connecting body and a second connecting body, and these connecting bodies are formed with a bent axis. By rotating these connecting bodies relative to each other around the axis of the connecting side, the relative orientation of the two connection ports can be changed, and this makes it easy to change the connection direction in this pipe joint.

The connection structure between the pipe joint and the cover member and the pipe joint device of this invention have the following advantages:

According to the connection structures between the pipe joint and the covering member described in claims 1 to 4 , and the pipe joint device described in claim 5 , the covering member covering the pipe joint will not fall off due to its own weight, due to the connection between the joinable part and the joining part.

Furthermore, according to the pipe joint device of the sixth aspect, by coupling the coupled part and the coupling part, the covering body (covering member) covering one of the connecting bodies (pipe joint) will not fall off due to its own weight.

The following describes the embodiment of the invention with reference to the drawings.

Figures 1 to 37 show one embodiment of the present invention. In the figures, reference numeral 1 denotes an air conditioner. Reference numeral 1a denotes a drain port of the air conditioner 1. Reference numeral 2 denotes a hanging bolt as a suspending device for suspending the air conditioner 1. Reference numeral 3 denotes a structure or other support. Reference numeral 4 denotes a drain pipe. Reference numeral 4a denotes a drain pipe end portion which is the end portion of the drain pipe 4. Reference numeral 5 denotes a drain path component. Reference numeral 6 denotes a drain structure.

The drainage path component 5 constitutes the drainage path between the drain outlet 1a of the air conditioner 1 and the drain pipe end 4a located above the drain outlet 1a. In other words, the air conditioner 1 is equipped with a pump that pressurizes the drainage water, and the drainage water is first lifted to the top of the drainage path by the pump and then falls.

This drainage path component 5 includes a cylindrical main body 7 whose interior is a drainage flow path, a first joint 8, and a second joint 9. The first joint 8 has a drain outlet side connection port 8a connected to the drain outlet 1a, and a main body one end side connection port 8b to which one end of the main body 7 is connected, and is bent so that its axis is approximately L-shaped (in the illustrated embodiment, the direction 8x of the drain outlet side connection port 8a and the direction 8y of the main body one end side connection port 8b are perpendicular directions). The second joint 9 has a main body other end side connection port 9a to which the other end side of the main body 7 is connected, and a drain pipe side connection port 9b to which the drain pipe end 4a is connected, and is formed so that it can be selectively changed between a parallel position in which the direction 9x of the main body other end side connection port 9a and the direction 9y of the drain pipe side connection port 9b are parallel directions, and a bent position in which the directions 9x and 9y intersect (in the illustrated embodiment, an orthogonal position in which they are perpendicular directions). Therefore, the drainage path component 5 has one end of the main body 7 connected to the one-end connection port 8b of the first joint 8, and the other end of the main body 7 connected to the other-end connection port 9a of the second joint 9, so that the main body 7, the first joint 8, and the second joint 9 are integrated.

In detail, the main body 7 includes a first pipe body 10, a second pipe body 11, and a curved flow path forming member 12 that is arranged above the first joint 8 and connects the first pipe body 10 and the second pipe body 11. In more detail, the curved flow path forming member 12 constitutes the apex of the drainage path between the drain outlet 1a of the air conditioner 1 and the drain pipe end 4a located above the drain outlet 1a, and its inside forms the curved drainage flow path 12a. The side of the first pipe body 10 opposite the curved flow path forming member 12 forms one end of the main body 7, and the side of the second pipe body 11 opposite the curved flow path forming member 12 forms the other end of the main body 7.

The first joint 8 is configured by separably connecting a cylindrical drain side member 801 having the drain side connection port 8a and a cylindrical first main body side member 802 having the main body one end side connection port 8b. Here, the first main body side member 802 is formed with a straight axis. The drain side member 801 is formed with a curved axis in a substantially L-shape, and the drain side member 801 can be connected to the first main body side member 802 at any rotation position rotated around the axis of the first main body side member 802, and this rotation makes it possible to orient the direction 8x of the drain side connection port 8a to any direction rotated around the axis of the first main body side member 802.

In addition, at the connecting sides of the drain side member 801 and the first main body side member 802 in the first joint 8, a first male thread portion 8c is formed on the outer peripheral surface of one of the members (in the illustrated embodiment, the drain side member 801), and a first connecting nut 8d is attached to the outer periphery of the other member (in the illustrated embodiment, the first main body side member 802) so as to be able to rotate freely, and the drain side member 801 and the first main body side member 802 are connected by screwing the first male thread portion 8c into the first connecting nut 8d. Here, the first connecting nut 8d has a first unevenness 8e formed along the circumferential direction on the end surface facing the one of the drain outlet side member 801 and the first main body side member 802 (the drain outlet side member 801), and the one of the drain outlet side member 801 and the first main body side member 802 (the drain outlet side member 801) has a first engagement portion 8f that engages with the first unevenness 8e when the first connecting nut 8d is screwed into the first male thread portion 8c. Therefore, the first unevenness 8e is formed in a sawtooth shape (preferably, in each tooth portion forming the sawtooth unevenness, the engaged surface in the loosening direction is an upright surface or a steeply inclined surface, and the engaged surface in the opposite direction, the tightening direction, is a gently inclined surface) so that the first engagement portion 8f that engages with the first unevenness 8e prevents the first connecting nut 8d from rotating in the loosening direction.

In addition, the other member (first body side member 802) of the drain port side member 801 and the first body side member 802 is provided with a first restricting protrusion 8g that restricts the first connecting nut 8d from moving further toward the loosening side (i.e., moving toward the loosening side in the axial direction of the first male screw portion 8c) by abutting the first connecting nut 8d with the first male screw portion 8c within one lead after the first connecting nut 8d is loosened from the first male screw portion 8c and disengaged from the first male screw portion 8c. The first connecting nut 8d is provided with a first recess 8h through which the first restricting protrusion 8g can pass at a predetermined rotation position of the first connecting nut 8d. Note that one lead refers to the distance that one screw member advances in the axial direction of the screw when one screw member (in the illustrated embodiment, the first connecting nut 8d) is rotated once in the screw engagement.

The second joint 9 has a positioning means 9c for positioning the parallel posture and the bent posture (orthogonal posture in the illustrated embodiment). The second joint 9 is configured by separably connecting a cylindrical second body side member 901 having the main body other end side connection port 9a and a cylindrical drain pipe side member 902 having the drain pipe side connection port 9b. Here, the second body side member 901 and the drain pipe side member 902 are both formed with a bent axis, and the second body side member 901 and the drain pipe side member 902 are connected at a rotational position rotated relatively around the axis of their connection side, thereby forming the parallel posture and the bent posture (orthogonal posture). Therefore, in order to position the second body side member 901 and the drain pipe side member 902 in the parallel position and the bent position (perpendicular position), a protrusion 9d is provided on one of the second body side member 901 and the drain pipe side member 902 (in the illustrated embodiment, the drain pipe side member 902), and a recess 9e that engages with the protrusion 9d is provided on the other member (in the illustrated embodiment, the second body side member 901). In other words, the positioning means 9c consists of these protrusions 9d and recesses 9e.

In addition, the second body side member 901 and the drain pipe side member 902 of the second joint 9 have an outer tube portion 9f on one side (the drain pipe side member 902 in the illustrated embodiment) at the connecting side of each other, and an inner tube portion 9g inserted into the outer tube portion 9f on the other side (the second body side member 901 in the illustrated embodiment). A ring-shaped water-stopping member 9h is fitted on the outer periphery of the inner tube portion 9g, and the water-stopping member 9h is in close contact with the inner periphery of the outer tube portion 9f. This water-stopping member 9h prevents the drain pipe side member 902 from moving toward the side that is detached from the second body side member 901 under its own weight until the engagement between the protrusion 9d and the recessed portion 9e is released.

In addition, at the connecting sides of the second body side member 901 and the drain pipe side member 902, a second male thread portion 9i is formed on the outer peripheral surface of one of the members (in the illustrated embodiment, the drain pipe side member 902), and a second connecting nut 9j is attached to the outer periphery of the other member (in the illustrated embodiment, the second body side member 901) so as to be able to rotate freely, and the second body side member 901 and the drain pipe side member 902 are connected by screwing the second male thread portion 9i into the second connecting nut 9j. Here, the second connecting nut 9j has a second unevenness 9k formed along the circumferential direction on the end surface facing the one of the second body side member 901 and the drain pipe side member 902 (the drain pipe side member 902), and the one of the second body side member 901 and the drain pipe side member 902 (the drain pipe side member 902) has a second engagement portion 9m that engages with the second unevenness 9k when the second connecting nut 9j is screwed into the second male thread portion 9i. Therefore, the second unevenness 9k is formed in a sawtooth shape (preferably, in each tooth portion forming the sawtooth unevenness, the engaged surface in the loosening direction is an upright surface or a steeply inclined surface, and the engaged surface in the opposite direction, the tightening direction, is a gently inclined surface) so that the second engagement portion 9m that engages with the second unevenness 9k prevents the second connecting nut 9j from rotating in the loosening direction.

In addition, the other member (second body side member 901) of the second body side member 901 and the drain pipe side member 902 is provided with a second restricting protrusion 9n that restricts further movement of the second connecting nut 9j toward the loosening side (i.e., movement toward the loosening side in the axial direction of the second male screw portion 9i) by abutting the second connecting nut 9j with the second male screw portion 9i within one lead after the second connecting nut 9j is loosened from the second male screw portion 9i and disengaged from the second male screw portion 9i (i.e., movement toward the loosening side in the axial direction of the second male screw portion 9i). The second connecting nut 9j is provided with a second recess 9p through which the second restricting protrusion 9n can pass at a predetermined rotation position of the second connecting nut 9j.

The curved flow path forming member 12 has a first pipe side connection port 12b to which the first pipe 10 is connected and a second pipe side connection port 12c to which the second pipe 11 is connected, and the inside becomes a curved drainage flow path 12a, which is a part of the drainage flow path. In other words, the first pipe side connection port 12b is connected to the first pipe side connection port 12b so that the inside of the first pipe 10 connected to the drain outlet 1a (more specifically, connected via the first joint 8) communicates with the curved drainage flow path 12a. And the second pipe side connection port 12c is connected to the second pipe side connection port 12c so that the inside of the second pipe 11 connected to the drain pipe end 4a (more specifically, connected via the second joint 9) communicates with the curved drainage flow path 12a.

The curved flow path forming member 12 is formed so that the angle 12x of the first pipe side connection port 12b and the angle 12y of the second pipe side connection port 12c are a right angle or a smaller angle (in the illustrated embodiment, a right angle). In other words, the first pipe side connection port 12b and the second pipe side connection port 12c are arranged so that the direction 12y of the second pipe side connection port 12c faces horizontally or downward (in the illustrated embodiment, the horizontal direction) with the direction 12x of the first pipe side connection port 12b facing vertically downward.

The curved flow path forming member 12 includes a curved flow path forming member main body 12d having the curved drainage flow path 12a, the first pipe body side connection port 12b, and the second pipe body side connection port 12c, and a fixing portion 12e that can be fixed to the support body 3. Here, the fixing portion 12e includes a mounting body 12g that has a mounting portion 12f that is attached to the support body 3 and is separate from the curved flow path forming member main body 12d, and an assembly portion 12h that is provided on the curved flow path forming member main body 12d and can be assembled to the mounting portion 12g. In the illustrated embodiment, the fixing portion 12e is provided on the opposite side of the curved flow path forming member 12 from the second pipe body side connection port 12c. The fixing portion 12e can be fixed to a bolt member (in the illustrated embodiment, a hanging bolt 2 that hangs the air conditioner 1) that serves as a support body 3 arranged near the air conditioner 1, and in the fixed state, the first pipe body 10 is arranged to extend downward from the curved flow path forming member 12.

The curved flow path forming member 12 also includes a lid 12i. Here, the curved flow path forming member body 12d has an opening 12j through which the curved drainage flow path 12a can be seen from the outside. The lid 12i is removably attached to the curved flow path forming member body 12d so as to close the opening 12j.

A valve body 13 is provided inside the curved flow path forming member 12 (more specifically, the curved flow path forming member main body 12d), and the valve body 13 normally closes the curved drainage flow path 12a and opens the curved drainage flow path 12a when drainage water from the first pipe body 10 flows in. The valve body 13 can be inserted and removed from the opening 12j. In detail, the curved flow path forming member 12 (more specifically, the curved flow path forming member main body 12d) has a bottom plate 12k and a protruding tubular portion 12m that protrudes upward from the bottom plate 12k in a cylindrical shape, and the inside of the protruding tubular portion 12m is connected to the inlet portion 12n into which drainage water from the first pipe body 10 flows in. Therefore, the valve body 13 is provided at the protruding end of the protruding tubular portion 12m.

In addition, the drainage path component 5 is provided with a cover member that covers one of the first joint 8 and the second joint 9 so as to accommodate it inside. In the illustrated embodiment, each of the first joint 8 and the second joint 9 is one of the joints, and a first cover member 14 that covers the first joint 8 so as to accommodate it inside and a second cover member 15 that covers the second joint 9 so as to accommodate it inside are provided as cover members. Here, the first joint 8 has a first coupled portion 8i formed on its outer surface as a coupled portion, and the first cover member 14 has a first coupling portion 14a formed on its inner surface as a coupling portion that couples with the first coupled portion 8i, and the first coupling portion 8i and the first coupling portion 14a are coupled to each other, so that the first cover member 14 is temporarily held by the first joint 8 so as not to fall under its own weight. Similarly, the second joint 9 has a second coupled part 9q formed on its outer surface as a coupled part, and the second covering member 15 has a second coupled part 15a formed on its inner surface as a coupling part that couples with the second coupled part 9q, and the coupling between the second coupled part 9q and the second coupled part 15a temporarily holds the second covering member 15 to the second joint 9 so that it does not fall under its own weight. In the illustrated embodiment, the first and second coupled parts 8i and 9q are made of convex parts, and the first and second coupled parts 14a and 15a are made of concave parts that fit into the convex parts and couple to the convex parts by friction.

In detail, the first covering member 14 has a cylindrical shape with an axis bent in a substantially L-shape, and covers the first joint 8 so as to accommodate it inside. This first covering member 14 has one or more (two in the illustrated embodiment) divided parts 14b extending along its axis, and by closing the divided parts 14b, it is possible to cover the first joint 8 so as to accommodate it inside.

Here, the first joint 8 has the first coupled portion 8i formed on the outer surface of the bent portion of the first joint 8, on the side away from the cross section cut by a plane including the axis of the first joint 8 (both sides in the illustrated embodiment). The first covering member 14 has the first coupled portion 14a formed on the inner surface of the bent portion of the first covering member 14, on the side away from the cross section cut by a plane including the axis of the first covering member 14 (both sides in the illustrated embodiment).

The covering member for the second body side member 151 and the covering member for the drain pipe side member 152 each have one or more (two in the illustrated embodiment) dividing sections 15b that extend along their axial direction, and by closing the dividing sections 15b, it is possible to cover the second body side member 901 and the drain pipe side member 902 so as to house them therein.

Here, the second connected portion 9q is formed on the outer surface of the bent portion of one of the second body side member 901 and the drain pipe side member 902, on the side away from the cross section cut by a plane including the axis of the one of the members (both sides in the illustrated embodiment). The second connected portion 15a that connects to the second connected portion 9q is formed on the inner surface of the covering member that covers the one of the second body side member covering member 151 and the drain pipe side member covering member 152 (more specifically, on the inner surface of the bent portion of the covering member, on the side away from the cross section cut by a plane including the axis of the covering member (both sides in the illustrated embodiment)), and the connection between the second connected portion 9q and the second connected portion 15a temporarily holds the covering member that covers the one of the members so that it does not fall by its own weight. In the illustrated embodiment, the second body side member 901 and the drain pipe side member 902 each serve as one of the members, and a second connecting portion 9q is provided on both the second body side member 901 and the drain pipe side member 902, and a second connecting portion 15a is provided on both the cover member 151 for the second body side member and the cover member 152 for the drain pipe side member.

The curved flow path forming body 17 is configured by including the cover member 16 for the curved flow path forming member in the curved flow path forming member 12. That is, the curved flow path forming body 17 includes the curved flow path forming member 12 and the cover member 16 for the curved flow path forming member that covers the curved flow path forming member 12 so as to accommodate it inside. The cover member 16 for the curved flow path forming member is divided into a main body cover part 16a that covers the curved flow path forming member main body 12d and a cover body cover part 16b that covers the cover body 12i. By removing the cover body cover part 16b from the main body cover part 16a, the cover body 12i can be removed from the curved flow path forming member main body 12d.

The curved flow path forming device 18 is configured by including the first pipe body 10 and/or the second pipe body 11 in the curved flow path forming member 12. That is, the curved flow path forming device 18 includes the curved flow path forming member 12, and the first pipe body 10 connected to the first pipe body side connection port 12b of the curved flow path forming member 12, and/or the second pipe body 11 connected to the second pipe body side connection port 12c. Here, the first pipe body 10 is connected to the first pipe body side connection port 12b of the curved flow path forming member 12 so as not to rotate around its axis, and similarly, the second pipe body 11 is connected to the second pipe body side connection port 12c of the curved flow path forming member 12 so as not to rotate around its axis.

The drainage device 19 is configured by including the first pipe body 10 and the first joint 8 in the curved flow path forming member 12. That is, the drainage device 19 includes the curved flow path forming member 12, the first pipe body 10 connected to the first pipe body side connection port 12b of the curved flow path forming member 12, and the bent first joint 8 connecting the first pipe body 10 to the drain outlet 1a of the air conditioner 1. Here, as described above, the first joint 8 is configured by connecting (more specifically, detachably connecting) a cylindrical drain outlet side member 801 having a drain outlet side connection port 8a connected to the drain outlet 1a, and a cylindrical pipe side member (i.e., the first main body side member 802) having a pipe side connection port (i.e., the main body one end side connection port 8b) to which the first pipe body 10 is connected. The first pipe 10 is connected to the first pipe side connection port 12b of the curved flow path forming member 12 so as not to rotate around its axis, and is also connected to the pipe side connection port (i.e., the main body one end side connection port 8b) of the first joint 8 (specifically, the first main body side member 802) so as not to rotate around its axis.

The drainage structure 6 has the fixing portion 12e of the curved flow path forming member 12 fixed to the support body 3, the first pipe body 10 connected to the downward facing first pipe body side connection port 12b of the curved flow path forming member 12, and the second pipe body 11 connected to the side facing second pipe body side connection port 12c. In this drainage structure 6, the first pipe body 10 is connected to the drain outlet 1a of the air conditioner 1, and the second pipe body 11 is connected to the drain pipe end 4a located above the drain outlet 1a.

In addition, in this drainage structure 6, the first pipe body 10 and the drain outlet 1a are connected via the first joint 8. The first joint 8 is covered with a first cover member 14, and the first cover member 14 has a dividing portion 14b extending along its axial direction. Similarly, the second pipe body 11 and the drain pipe end portion 4a are connected via a second joint 9. The second joint 9 is covered with a second cover member 15 (i.e., the aforementioned second body side member cover member 151 and drain pipe side member cover member 152), and the second cover member 15 has a dividing portion 15b extending along its axial direction. Therefore, each cover member (i.e., the first cover member 14 and the second cover member 15) is wrapped with a joining member 20 such as adhesive tape to prevent the dividing portions 14b and 15b from opening.

In addition, in this drainage structure 6, the curved flow path forming member 12 is covered with a cover member 16 for the curved flow path forming member. As described above, the curved flow path forming member 12 includes a curved flow path forming member main body 12d having an opening 12j, and a cover body 12i that closes the opening 12j. Accordingly, the cover member 16 for the curved flow path forming member is divided into a main body cover part 16a that covers the curved flow path forming member main body 12d, and a cover body cover part 16b that covers the cover body 12i. Here, the main body cover part 16a includes two divided bodies 16c, 16c that are divided so as to sandwich the first pipe body side connection port 12b, the second pipe body side connection port 12c, and the fixing part 12e (in the illustrated embodiment, in addition, so as to sandwich the opening 12j), and a joining member 20 such as an adhesive tape is wrapped around the main body cover part 16a so that the divided bodies 16c, 16c do not separate.

By the way, the first joint 8 is not limited to being used in the drainage path of the air conditioner 1, but can also be understood as a pipe joint having a connection port (drain port side connection port 8a, main body one end side connection port 8b) with the pipe body (drain port 1a, first pipe body 10) at both ends. Similarly, the second joint 9 can also be understood as a pipe joint having a connection port (main body other end side connection port 9a, drain pipe side connection port 9b) with the pipe body (second pipe body 11, drain pipe 4) at both ends. Therefore, this pipe joint (first pipe joint 8 or second pipe joint 9) has a cylindrical first connecting body (drain port side member 801 or second main body side member 901) having a connection port (main body one end side connection port 8b or main body other end side connection port 9a) at one end, and a cylindrical second connecting body (first main body side member 802 or drain pipe side member 902) having a connection port (main body one end side connection port 8b or drain pipe side connection port 9b) at one end.

The first and second connecting bodies are connected to each other by forming a male thread (first male thread 8c or second male thread 9i) on the outer periphery of one of the connecting bodies (in the illustrated embodiment, the drain outlet side member 801 or the drain pipe side member 902), and a connecting nut (first connecting nut 8d or second connecting nut 9j) is attached to the outer periphery of the other connecting body (in the illustrated embodiment, the first main body side member 802 or the second main body side member 901) so as to be able to rotate freely. The first and second connecting bodies are connected by screwing the male thread (first male thread 8c or second male thread 9i) and the connecting nut (first connecting nut 8d or second connecting nut 9j).

Here, the end face of the connecting nut (first connecting nut 8d or second connecting nut 9j) facing the connecting body on one side (drain outlet side member 801 or drain pipe side member 902) is formed with unevenness (first unevenness 8e or second unevenness 9k) along the circumferential direction, and the connecting body on one side (drain outlet side member 801 or drain pipe side member 902) is provided with an engaging portion (first engaging portion 8f or second engaging portion 9m) that engages with the unevenness (first unevenness 8e or second unevenness 9k) when the connecting nut (first connecting nut 8d or second connecting nut 9j) is screwed into the male thread portion (first male thread portion 8c or second male thread portion 9i). Therefore, the unevenness (first unevenness 8e and second unevenness 9k) is formed in a sawtooth shape so that the engagement portion (first engagement portion 8f and second engagement portion 9m) that engages with the unevenness (first unevenness 8e and second unevenness 9k) prevents the connecting nut (first connecting nut 8d and second connecting nut 9j) from rotating in the loosening direction.

The other connecting body (first body side member 802 or second body side member 901) is provided with a restricting protrusion (first restricting protrusion 8g or second restricting protrusion 9n) that restricts further movement of the connecting nut (first connecting nut 8d or second connecting nut 9j) toward the loosening side (i.e., movement toward the loosening side in the axial direction of the male threaded portion) by abutting the connecting nut (first connecting nut 8d or second connecting nut 9j) with the male threaded portion (first male threaded portion 8c or second male threaded portion 9i) with a movement of within one lead toward the loosening side (i.e., movement of within one lead toward the loosening side in the axial direction of the male threaded portion) after the connecting nut (first connecting nut 8d or second connecting nut 9j) is loosened from the male threaded portion (first male threaded portion 8c or second male threaded portion 9i) and disengaged from the male threaded portion. Furthermore, the connecting nut (first connecting nut 8d or second connecting nut 9j) is provided with a recess (first recess 8h or second recess 9p) through which the restricting protrusion (first restricting protrusion 8g or second restricting protrusion 9n) can pass when the connecting nut (first connecting nut 8d or second connecting nut 9j) is in a predetermined rotational position.

As described above, the second joint 9 can be understood as a pipe joint having connection ports (main body other end connection port 9a, drain pipe side connection port 9b) at both ends for connection to the pipe body (second pipe body 11, drain pipe 4), and the pipe joint device is made up of this pipe joint (second pipe joint 9) and a cover member (second cover member 15) that covers the pipe joint (second pipe joint 9) so as to accommodate it inside. In other words, the pipe joint device comprises the pipe joint (second pipe joint 9) and the cover member (second cover member 15). In detail, the pipe joint (second pipe joint 9) comprises a cylindrical first connector (second body side member 901) having a connection port (main body other end side connection port 9a) at one end, and a cylindrical second connector (drain pipe side member 902) having a connection port (drain pipe side connection port 9b) at one end, and the other ends of the first connector (second body side member 901) and the second connector (drain pipe side member 902) are connected to each other. The first connector (second body side member 901) and the second connector (drain pipe side member 902) are both formed with a bent axis, and the first connector (second body side member 901) and the second connector (drain pipe side member 902) are connected at a rotational position rotated relative to the axis of the connection side, so that the relative orientation of both connectors (main body other end side connection port 9a and drain pipe side connection port 9b) can be changed.

On the other hand, the covering member (second covering member 15) is composed of a cylindrical first covering body (covering member for second body side member 151) with a bent axis that covers the first connecting body (second body side member 901) so as to accommodate it inside, and a cylindrical second covering body (covering member for drain pipe side member 152) with a bent axis that covers the second connecting body (drain pipe side member 902) so as to accommodate it inside, and each covering body has one or more dividing parts (dividing parts 15b) extending along its axis direction, and by closing the dividing parts (dividing parts 15b), it is possible to cover the first connecting body (second body side member 901) and the second connecting body (drain pipe side member 902) so as to accommodate them inside.

Here, one of the connecting bodies (in the illustrated embodiment, each connecting body) between the first connecting body (second main body side member 901) and the second connecting body (drain pipe side member 902) has a connecting portion (second connecting portion 9q) formed on its outer surface. The cover (cover member 151 for second body side member, cover member 152 for drain pipe side member) covering one of the connecting bodies (second body side member 901, drain pipe side member 902) in the first cover (cover member 151 for second body side member) and the second cover (cover member 152 for drain pipe side member) has a connecting portion (second connecting portion 15a) that connects to the connecting portion (second connecting portion 9q) formed on its inner surface, and the connecting portion (second connecting portion 15a) is connected to the connecting portion (second connecting portion 9q) so that the cover (cover member 151 for second body side member, cover member 152 for drain pipe side member) covering one of the connecting bodies (second body side member 901, drain pipe side member 902) is temporarily held to the one of the connecting bodies (second body side member 901, drain pipe side member 902) by the connection between the connecting portion (second connecting portion 9q) and the connecting portion (second connecting portion 15a).

Here, the pipe bodies 10a, 11a are made of, for example, synthetic resin, and the covering materials 10b, 11b are made of a heat insulating material. At least the second pipe body 11 is flexible. In the illustrated embodiment, the first pipe body 10 and the second pipe body 11 are flexible, and the second pipe body 11 is formed to have a shorter axial length than the first pipe body 10.

As described above, the first joint 8 is connected between the drain port side member 801 and the first main body side member 802 via the first connecting nut 8d.

As described above, the second joint 9 is connected between the second body side member 901 and the drain pipe side member 902 via the second connecting nut 9j. In detail, a U-shaped retaining ring 9r is attached to the outer periphery of the second body side member 901. The second connecting nut 9j is a water-related bag nut, and the second connecting nut 9j is prevented from coming off the outer periphery of the second body side member 901 by the retaining ring 9r and is tightened to the second male threaded portion 9i. At this time, the tip portion of the second body side member 901 (i.e., the aforementioned inner tube portion 9g) is inserted into the drain pipe side member 902 (more specifically, the aforementioned outer tube portion 9f), and the ring-shaped water-stopping member 9h fitted to the outer periphery of the inserted tip portion is in close contact with the inner periphery of the drain pipe side member 902 (more specifically, the aforementioned outer tube portion 9f).

As described above, the second body side member 901 and the drain pipe side member 902 are both formed with a bent axis, but in the illustrated embodiment, this bend is 45° from a straight state. Therefore, the second body side member 901 and the drain pipe side member 902 are connected at a rotational position where their axis centers are located on the same plane and rotated 180° relative to the axis of their connecting side, thereby forming the above-mentioned parallel and orthogonal positions.

In addition, with regard to the aforementioned protrusion 9d and recess 9e in the second joint 9, the protrusion 9d is formed so as to protrude from the tip surface of the drain pipe side member 902 facing the second main body side member 901. And the recess 9e is formed so as to be recessed from the surface of the retaining ring 9r provided on the second main body side member 901 facing the drain pipe side member 902.

In addition, in this second joint 9, the main body other end side connection port 9a is composed of an inner tubular portion 9s, an intermediate tubular portion 9t, and an outer tubular portion 9u, which are arranged concentrically. The pipe main body 11a of the second pipe body 11 is inserted between the inner tubular portion 9s and the intermediate tubular portion 9t, and the covering material 11b of the second pipe body 11 is inserted between the intermediate tubular portion 9t and the outer tubular portion 9u, and is fixed to the main body other end side connection port 9a by, for example, gluing. The drain pipe side connection port 9b has a large diameter portion 9v and a small diameter portion 9w to correspond to the different diameters of the drain pipe 4. In the illustrated embodiment, the diameter of the drain pipe 4 is large, and the drain pipe 4 (more specifically, the drain pipe end portion 4a) fits into the large diameter portion 9v of the drain pipe side connection port 9b.

The curved flow path forming member 12 includes the curved flow path forming member main body 12d, the fixing portion 12e, and the cover body 12i. The curved flow path forming member main body 12d includes a cylindrical connector 12p having a second pipe side connection port 12c as a separate body, and the connector 12p is connected to the main body portion 12q excluding the connector 12p via a connecting nut 12r (having the same shape as the first connecting nut 8d described above). In detail, the main body portion 12q has a main body cylindrical portion 12s and an extension cylindrical portion 12t extending laterally from the main body cylindrical portion 12s, and a male screw portion 12u is formed on the outer circumferential surface of the extension cylindrical portion 12t. The connecting nut 12r is attached to the connector 12p around its outer periphery so as to be able to rotate freely, and the connector 12p is connected to the main body portion 12q by screwing the male screw portion 12u and the connecting nut 12r together. More specifically, a U-shaped retaining ring 12v (same shape as the retaining ring 9r described above) is attached to the outer periphery of the connecting body 12p. The connecting nut 12r is a water-resistant cap nut, and the retaining ring 12v prevents the connecting nut 12r from coming off the outer periphery of the connecting body 12p and tightens it onto the male threaded portion 12u. At this time, the tip of the connecting body 12p is inserted into the extended cylindrical portion 12t, and the ring-shaped water-stopping member 12w fitted to the outer periphery of the inserted tip is in close contact with the inner periphery of the extended cylindrical portion 12t.

In addition, the first pipe side connection port 12b is formed in the curved flow path forming member main body 12d (more specifically, the main body cylindrical portion 12s) so as to protrude downward from the bottom plate 12k. This first pipe side connection port 12b is composed of an inner cylindrical portion 120a, an intermediate cylindrical portion 120b, and an outer cylindrical portion 120c, which are arranged concentrically. The pipe main body 10a of the first pipe body 10 is inserted between the inner cylindrical portion 120a and the intermediate cylindrical portion 120b, and the covering material 10b of the first pipe body 10 is inserted between the intermediate cylindrical portion 120b and the outer cylindrical portion 120c, and is fixed to this first pipe side connection port 12b by, for example, adhesive or the like. The inside of the inner cylindrical portion 120a becomes the inflow portion 12n into which the wastewater from the first pipe body 10 flows. Similarly, the second pipe side connection port 12c is composed of an inner tube portion 120d, an intermediate tube portion 120e, and an outer tube portion 120f, which are arranged concentrically.

The protruding tube portion 12m provided on the curved flow path forming member main body 12d (specifically, the main body tube portion 12s) has a plurality of ribs 120g, 120g radially arranged to connect the protruding end and the center, and a through hole 120h is opened in the center where the ribs 120g, 120g gather. Thus, the drainage passes between the ribs 120g, 120g and enters the inside. The valve body 13 is then attached to the through hole 120h. In detail, the valve body 13 is composed of a disk-shaped valve body 13a and an attachment protrusion 13b protruding from the center of the valve body 13a. Thus, the valve body 13a is placed on the protruding end of the protruding tube portion 12m, and the attachment protrusion 13b is inserted into the through hole 120h and engaged.

The opening 12j of the curved flow path forming member main body 12d (more specifically, the main body tubular portion 12s) is located above the bottom plate 12k and is provided to open upward. The lid body 12i that closes this opening 12j is attached so as to fit inside the curved flow path forming member main body 12d (more specifically, the main body tubular portion 12s). This lid body 12i is positioned opposite the valve body 13. A ring-shaped water-stopping member 120i is fitted to the outer periphery of the lid body 12i, and the water-stopping member 120i is in close contact with the circumferential surface of the opening 12j.

As described above, the fixing portion 12e of the curved flow path forming member 12 includes a mounting body 12g having a mounting portion 12f and an assembly portion 12h.

As described above, the cover member 16 for the curved flow path forming member is divided into a main body cover part 16a and a lid body cover part 16b, and these main body cover part 16a and lid body cover part 16b are assembled by fitting them together. The main body cover part 16a has the above-mentioned divided bodies 16c, 16c, and this main body cover part 16a has a groove 16d that goes around the entire circumference at the end on the side that sandwiches the first pipe side connection port 12b and the end on the side that sandwiches the second pipe side connection port 12c, and the above-mentioned joining member 20 is wrapped around the groove 16d.

Next, the effects of the drainage path component 5 and drainage structure 6, which are configured as described above, will be described. The drainage path component 5 constitutes a drainage path from the drain outlet 1a of the air conditioner 1 to the drain pipe end 4a located above the drain outlet 1a, and includes a cylindrical main body 7, 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 first joint 8 is bent so that its axis is approximately L-shaped (in the illustrated embodiment, the direction 8x of the drain outlet side connection port 8a connected to the drain outlet 1a and the direction 8y of the main body one end side connection port 8b to which one end of the main body 7 is connected are perpendicular directions). The second joint 9 can be selectively changed between a parallel position in which the orientation 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 orientation 9y of the drain pipe side connection port 9b to which the drain pipe end 4a is connected are parallel, and a bent position in which the orientations 9x and 9y intersect (in the illustrated embodiment, an orthogonal position in which they are perpendicular). In this way, since the second joint 9 can be changed between a parallel position and a bent position (orthogonal position), the connection direction of the second joint 9 can be easily changed, and by selecting either the parallel position or the bent position (orthogonal position), it is possible to easily respond to the situation of the location where the drainage path component 5 is placed.

The first joint 8 is configured by connecting a drain outlet side member 801 whose axis is formed in a substantially L-shape to a first main body side member 802 whose axis is formed in a straight line. The drain outlet side member 801 can be connected to the first main body side member 802 at any position rotated about the axis of the first main body side member 802. Therefore, by rotating the drain outlet side member 801 and changing the direction 8x of the drain outlet side connection port 8a in the drain outlet side member 801, the drain outlet side connection port 8a can be easily directed toward the drain outlet 1a of the air conditioner 1.

The second joint 9 is configured by connecting a second body side member 901 and a drain pipe side member 902, and the second body side member 901 and the drain pipe side member 902 are positioned in the parallel posture and the bent posture (orthogonal posture in the illustrated embodiment) by the engagement of the protrusion 9d and the recess 9e. A water stop member 9h is interposed between the second body side member 901 and the drain pipe side member 902, and the water stop member 9h prevents the drain pipe side member 902 from moving toward the side detached from the second body side member 901 due to its own weight until the engagement between the protrusion 9d and the recess 9e is released. In this way, the water-stopping member 9h maintains the engagement between the protrusion 9d and the recess 9e, maintaining the parallel or bent (orthogonal) position of the second joint 9, facilitating the assembly of the second joint 9 (assembly of the second body side member 901 and the drain pipe side member 902, specifically, assembly including screwing the second connecting nut 9j into the second male threaded portion 9i).

The main body 7 includes a first pipe 10, a second pipe 11, and a curved flow path forming member 12 that connects the first pipe 10 and the second pipe 11. By providing an opening 12j and a cover 12i in the curved flow path forming member 12 located midway through the main body 7 (and thus midway through the drainage path), the internal curved drainage flow path 12a can be inspected.

A valve body 13 is provided inside the curved 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. Also, by providing the valve body 13 at the protruding end of the protruding tubular portion 12m that protrudes upward from the bottom plate 12k, impurities such as dust contained in the wastewater sink onto the bottom plate 12k, preventing the impurities from adhering to the valve body 13, and allowing the movement of the valve body 13 to be maintained for a long time.

The curved flow path forming member 12 constitutes the apex of the drainage path, and has a first pipe side connection port 12b to which the first pipe 10 connected to the drain outlet 1a of the air conditioner 1 is connected, and a second pipe side connection port 12c to which the second pipe 11 connected to the drain pipe end 4a located above the drain outlet 1a is connected. When the direction 12x of the first pipe side connection port 12b is vertically downward, the direction 12y of the second pipe side connection port 12c faces horizontally or lower than that (horizontally in the illustrated embodiment). By using the curved flow path forming member 12 at the apex of the drainage path, the direction of the second pipe 11 relative to the first pipe 10 can be changed, and bending of the pipe itself can be suppressed. In addition, the curved flow path forming member 12 has a fixing portion 12e that can be fixed to the support 3, and the curved flow path forming member 12 itself is supported by fixing the fixing portion 12e to the support 3. In other words, by using the curved flow path forming member 12 at the apex of the drainage path, the bending of the pipe itself can be suppressed, and by providing the fixing portion 12e on the curved flow path forming member 12, the curved flow path forming member 12, i.e., the apex of the drainage path, can be easily supported.

The fixing portion 12e is provided on the opposite side of the curved flow path forming member 12 from the second pipe side connection port 12c. This ensures that the support 3 does not interfere with the arrangement of the second pipe 11 connected to the second pipe side connection port 12c, or the drain pipe 4 to which the second pipe 11 is connected.

The fixing portion 12e also includes a mounting body 12g having a mounting portion 12f that is attached to the support body 3, and an assembly portion 12h that is provided on the curved flow path forming member main body 12d and can be assembled to the mounting body 12g. As a result, when fixing the fixing portion 12e to the support body 3, the mounting portion 12f (mounting body 12g) can be attached to the support body 3 first, and then the assembly portion 12h provided on the curved flow path forming member main body 12d can be assembled to the mounting body 12g. In particular, in the illustrated embodiment, the assembly portion 12h (more specifically, the arm portion 120p) is pressed against the mounting body 12g (more specifically, the assembled portion 120m), so that the assembled portion 120m enters the mounting hole 120q provided in the arm portion 120p, and the assembly portion 12h is assembled to the mounting body 12g, making the assembly easy.

The first tube 10 and the second tube 11 are flexible, and the second tube 11 is formed to have a shorter axial length than the first tube 10. By forming the second tube 11 to be short, the second tube 11 is less likely to corrugate.

In addition, the pipe joint (for example, the first joint 8 or the second joint 9) comprises a first connecting body (the drain outlet side member 801 or the second main body side member 901) and a second connecting body (the first main body side member 802 or the drain pipe side member 902), and these connecting bodies are connected by screwing a connecting nut (the first connecting nut 8d or the second connecting nut 9j) rotatably attached to the connecting body on the other side (in the illustrated embodiment, the first main body side member 802 or the second main body side member 901) onto a male threaded portion (the first male threaded portion 8c or the second male threaded portion 9i) formed on the connecting body on one side (in the illustrated embodiment, the drain outlet side member 801 or the drain pipe side member 902). Therefore, when the connecting nut (first connecting nut 8d or second connecting nut 9j) is screwed onto the male threaded portion (first male threaded portion 8c or second male threaded portion 9i), the first connecting body and the second connecting body are rotated relatively around the axis of their connecting sides, making it possible to change the relative orientation of both connection ports (the drain port side connection port 8a and the main body one end side connection port 8b, or the main body other end side connection port 9a and the drain pipe side connection port 9b), thereby making it possible to easily change the connection direction of this pipe joint.

The other connecting body (first body side member 802 or second body side member 901) is provided with a restricting protrusion (first restricting protrusion 8g or second restricting protrusion 9n) that restricts the movement of the connecting nut (first connecting nut 8d or second connecting nut 9j) toward the loosening side, and the connecting nut (first connecting nut 8d or second connecting nut 9j) can be quickly screwed into the male thread (first male thread 8c or second male thread 9i) while avoiding unnecessary retraction of the connecting nut. The connecting nut (first connecting nut 8d or second connecting nut 9j) is provided with a recess (first recess 8h or second recess 9p) through which the restricting protrusion (first restricting protrusion 8g or second restricting protrusion 9n) can pass at a predetermined rotational position of the connecting nut, and the retaining ring (retaining ring 8j or retaining ring 9r) can be attached or detached by retracting the connecting nut so that the restricting protrusion passes through the recess. In addition, in the second connecting nut 9j, the positional relationship between the protrusion 9d, which is the positioning means 9c, and the recess 9e can be visually confirmed by retracting the connecting nut 9j so that the restricting protrusion 9n passes through the recess 9p.

The pipe joint (e.g., second joint 9) has a first connecting body (second main body side member 901) and a second connecting body (drain pipe side member 902), and these connecting bodies are formed with a bent axis. By rotating these connecting bodies relative to each other around the axis of their connecting sides, the relative orientation of both connection ports (main body other end side connection port 9a and drain pipe side connection port 9b) can be changed, and this makes it easy to change the connection direction in this pipe joint.

The present invention is not limited to the above-mentioned embodiment, and various other modifications are possible. For example, in the drainage path component 5, the main body 7 does not have to include the first pipe body 10, the second pipe body 11, and the curved flow path forming member 12, and may be composed of a single pipe body 7a (more specifically, a flexible pipe body) as shown in Figures 38 and 39.

The first pipe 10 connected to the first pipe side connection port 12b in the curved flow path forming member 12 is connected to the drain outlet 1a via the first joint 8, but may be connected directly without the first joint 8. Similarly, the second pipe 11 connected to the second pipe side connection port 12c in the curved flow path forming member 12 is connected to the drain pipe end 4a via the second joint 9, but may be connected directly without the second joint 9.

The fixing portion 12e also includes a mounting body 12g having a mounting portion 12f that is attached to the support body 3, and an assembly portion 12h that can be attached to the mounting body 12g. However, the mounting body 12g may be provided directly on the curved flow path forming member main body 12d without including the assembly portion 12h.

In addition, instead of using the hanging bolts 2 for hanging the air conditioner 1, a dedicated bolt member (hanging bolt) for hanging the curved flow path forming member 12 may be used as the support member 3. In addition, the support member 3 is not limited to a bolt member, and may be a support member provided on the air conditioner 1 or another structure, etc.

The first tube 10 and the second tube 11 are formed so that the second tube 11 has a shorter axial length than the first tube 10, but this is not limited thereto, and they may be the same length or the first tube 10 may be shorter.

The first joint 8 and the second joint 9 are covered by the first covering member 14 and the second covering member 15, but one or both of the first covering member 14 and the second covering member 15 may be omitted. Similarly, the curved flow path forming member 12 is covered by the curved flow path forming member covering member 16, but this curved flow path forming member covering member 16 may be omitted.

The first joint 8 is provided with a first joint part 8i, and the first cover member 14 is provided with a first connecting part 14a, but these first joint part 8i and first connecting part 14a may be omitted. Similarly, the second joint 9 (the second body side member 901 and the drain pipe side member 902) is provided with a second joint part 9q, and the second cover member 15 (the cover member for the second body side member 151 and the cover member for the drain pipe side member 152) is provided with a second connecting part 15a, but these second joint part 9q and second connecting part 15a may be omitted, and the second joint part 9q and second connecting part 15a may be provided only on either the second body side member 901 and the cover member for the second body side member 151, or the drain pipe side member 902 and the cover member for the drain pipe side member 152.

In addition, the first covering member 14 and the second covering member 15 have the joining member 20 wrapped around the grooves 14d and 15d, but this joining member 20 is not limited to the grooves 14d and 15d, and may be wrapped around the entire member, for example. The same is true for the covering member 16 for the curved flow path forming member, and the joining member 20 is not limited to the groove 16d, and may be wrapped around the entire member, for example.
