Description

  The present invention relates to a drain pipe fitting for an air conditioner concealment pipe for a house or the like.

When assembling an indoor unit to a housing unit or the like, especially when incorporating the indoor unit into the ceiling of the room, the drain pipe for guiding the drainage from the drain port of the indoor unit to the outside needs to be installed with a predetermined gradient. . In the traditional wooden Japanese house, the floor was supported by joists and large pulls, so there was a gap below the floor, and this gap was used as a piping space, and the hard vinyl chloride pipe was arranged with a gradient. The present assembly type house has a floor space directly attached to the beam, so there is no piping space, and a notch is formed in the beam, and this notch is required to be the minimum from the viewpoint of maintaining the strength of the beam. In order to allow the drain pipe to pass through the notch, a heat insulating drain pipe having flexibility and elasticity is connected to the drain port of the indoor unit, and the notch has a gradient at the back of the ceiling. Connected to the horizontally-stretched hard vinyl chloride pipe arranged at the end, and when the horizontal pulling part is finished, the heat-insulated drain pipe is connected to the lower end opening of the hard vinyl chloride pipe, and this heat-insulated drain pipe is routed downstairs between the inner and outer walls It was hanging down.
However, in the conventional drain pipe mounting method for a housing air conditioner system, a hard vinyl chloride pipe is used for the laterally drawn portion of the ceiling, and both ends of the hard vinyl chloride pipe have flexible heat insulating drain pipes. Are connected. In other words, since it uses various parts such as the insulated drain pipe, hard vinyl chloride pipe, and vertical hand from the drain port of the indoor unit to the drain outlet to the outdoors, it is costly, and the insulated drain pipe and hard vinyl chloride are used. Since an adhesive is used to connect to the connection portion with the pipe, there has been a situation where water leaks from the connection portion.
Further, as a drain pipe fitting for preventing the drain pipe from being bent behind the ceiling, there is one in which both ends of a duct having a fixed shape are supported by spring leg members having different heights. (For example, refer to Patent Document 1). If it is the drain piping fixture of this patent document 1, a load will be applied to a ceiling and it is not preferable.
Japanese Patent Application Laid-Open No. 10-73276.

  The present invention relates to a drain pipe fitting for an air conditioner concealment pipe that uses the same single heat-insulated drain pipe from the drain port of the indoor unit to the outdoor drain port and can reduce the cost without applying a load to the ceiling. The purpose is to provide.

  In order to achieve the above object, the present invention provides a drain pipe fitting for an air conditioner concealment pipe for attaching a drain pipe for an indoor unit to a ceiling back portion with a predetermined gradient, and can accommodate a heat insulating drain pipe inside. A lower cover that is provided over the entire length in the longitudinal direction of the drain pipe holder having a size, has an opening through which the drain pipe can enter and exit inside the drain pipe holder, and continuously projects outward from the opening edge, Nuts can be stored inside by a side cover that rises substantially perpendicularly from the outer edge of the lower cover and an upper cover that extends inwardly from the upper edge of the side cover and that is provided with bolt insertion holes. A space portion is provided to form a nut housing portion, and mounting plates that project outward are provided on both the left and right sides of the nut housing portion, and this mounting plate has mounting means for mounting a drain pipe fitting to the beam. And wherein the digit.

  In the present invention, a flexible heat-insulating drain pipe can be arranged without bending in the back of the ceiling, and can be suspended from a beam using bolts and nuts using a suspension band, or using screws or nails. This has the effect that it can be applied to any mounting method such as mounting on a wall.

  FIG. 1 is a perspective view of a drain pipe fitting for an air conditioner concealing pipe according to the present invention, FIG. 2 is a side view showing a state in which an upper cover of the drain pipe fitting for an air conditioner concealing pipe of this embodiment is closed, and FIG. It is explanatory drawing which shows a state. In these drawings, the drain pipe holder 1 is made of a synthetic resin such as polypropylene, and is formed in a cylindrical shape that is remarkably long in one direction so that the drain pipe 2 can be accommodated inside and is open at both ends. The drain pipe holder 1 is provided with an opening 3 through which the drain pipe 2 can be taken in and out along the longitudinal direction. Side covers 6 and 7 are continuously provided to rise at an angle of approximately 90 degrees from the edges of the lower covers 4 and 5 continuously projecting outward from the opening edge of the opening 3. The upper covers 8 and 9 are continuously provided inward at an angle of 90 degrees with respect to the side covers 6 and 7 from the upper end edge of 7. The side covers 6 and 7 are formed so that the length in the height direction is longer than the height of the nut 10. The upper covers 8 and 9 are formed so as to overlap each other when folded inward with the upper edges of the side covers 6 and 7 as fold lines, and bolts 11 that are screwed onto the nuts 10 are inserted into the upper cover 8. Bolt insertion holes 12 that are long in the axial direction are formed at predetermined intervals along the axial direction of the drain pipe holder 1. The upper cover 9 is formed with a plain-view T-shaped bolt insertion groove 13 that opens at the edge of the upper cover 9 at a position that coincides with the upper covers 8 and 9 that are overlapped. The mounting plates 14 and 15 are arranged on the upper side of the side covers 6 and 7 so that they are located at the same position as the height of the upper covers 8 and 9 when the upper covers 8 and 9 are stacked one on top of the other and the opening 3 is closed. A fastener insertion hole 16 is bored along the length direction.

Next, a usage method will be described with reference to FIG. The drain pipe 2 lowered from the inner and outer wall surfaces of the upper floor is stored in the drain pipe holder 1 under the floor, the upper covers 8 and 9 are superposed, the mounting plates 14 and 15 are brought into contact with a horizontal member such as a beam, and the fastener 17 is attached. The fastener insertion hole 16 is passed through and fastened.
Also, as shown in FIGS. 4 and 5, the drain pipe 2 descending from the upper floor is stored in the drain pipe holder 1, and the upper covers 8 and 9 superposed by the nuts 10 and 18 and the bolts 11 are fastened, Bolts 11 are attached to a battledore 22 attached to the beam 21, and the drain pipe 2 is disposed behind the ceiling. Further, as shown in the drain pipe fitting 23 for the air conditioner concealment pipe disposed on the right side in FIG. 5, the fastener 17 is attached to the beam 21.
