Description

[Detailed Description of the Invention] The present invention relates to a drainage device for an air conditioner.

The conventional air conditioner has a main body base 11 as shown in Figure 5a.
Either a hole is made in the side edge of the main body base 11 and a drain pipe 12 having a tapered drain port is pushed out from the inside and installed, or a U-shaped notch is formed on one side of the main body base 11 as shown in FIG. A drainage pipe 13 with a corresponding U-shaped retaining edge was inserted from above. However, these drain pipes 12 and 13 are made of an elastic material to facilitate installation and to ensure a complete seal at the installation part, but when installing the main body 14 from the drainage side as shown in Figure 4. When placed, the end of the drain pipe 12 or 13 hits the stand 15 etc. due to the tilt, and a force is applied to push it upward diagonally, causing the drain pipe 12 or 13 to come off, or the attachment part to shift, and the seal part to be damaged. It had drawbacks such as being incomplete and causing water leaks.

The present invention eliminates the drawbacks of the above conventional type.
To explain the present invention with reference to an embodiment shown in the figure below, 1 is the main body base of an air conditioner, and the main body base 1 is formed into a dish shape that also serves as a receptacle for the required amount of water by pressing a metal plate or the like. A rectangular hole 2 is made in one side edge of the main body base 1 as shown in FIG. On the other hand, a drainage pipe 3 as shown in Fig. 3 is formed from an elastic material such as synthetic rubber, and the drainage pipe 3 is provided with a fitting groove 4 corresponding to the hole 2, and the outside is provided along the outer periphery of the pipe. A flange-like part 6 is formed with an annular recess 5, and a tapered square insertion part 7 is formed on the inside for insertion into the hole 2, and one side of the insertion part 7 has an insertion end. A rectangular water inlet 10 with a partition edge 9 for regulating a predetermined water level is formed in the drain outlet part 8 of the other side.
communicate with.

When attaching the drain pipe 3 to the main body base 1 with the above configuration, simply insert the press rod 14 as shown in Fig. 1 and press it from the outside to use its elastic deformation to fit the fitting groove 4 into the hole 2. Can be inserted. In this way, the drain pipe 3 attached to the main body base 1 is installed in the same direction against external forces, so it will not fall off, and in particular, the force applied to the pipe by the recess 5 can be absorbed by the flange 6. It can be difficult to convey to others. Further, the flanged portion 6 has a sufficient contact area with the side wall of the main body base 1, and can ensure sufficient sealing performance. Furthermore, the drainage pipe 3 can be mounted in the square hole 2 and rotated in 90° increments to change the position of the water inlet 10, making it easy to change the water level inside the main body base 1 according to the position of the partition edge 9. can do.
