2, and work from at least two directions of the air conditioner body 1 is required, which makes the work difficult and reduces work efficiency. However, with the auxiliary drain pan, there was a problem in that it was difficult to attach and remove the drain pan.

This idea solves the above problems and
To provide an air conditioner that can easily attach and detach a drain pan from one direction even when it has an auxiliary drain pan, and can improve its working efficiency.

[Means for solving problems]

The air conditioner according to this invention is provided with hooks on both sides of the drain tray, these hooks are hooked onto hooks provided on the main body of the air conditioner, and one of the hooks is fastened to a hook receiver. At the same time, the hook portion on one side is formed in the shape of a crank that forms a groove inside the side wall of the drain tray.

[Effect]

In the air conditioner according to this invention, the drain tray mounting device hooks the hooks provided on both sides of the drain tray to the hook receivers provided on the air conditioner body, so the hooks can be attached to one place. If you fasten it to the hook receptacle, the drain pan will not come off, and only one fastening member is required.Also, the drain pan can be attached and removed from one direction when the air conditioner is mounted on the ceiling, and the auxiliary drain pan can be attached and removed from one direction. Even if the drain plate has a hook, the drain plate can be attached and detached from one direction by loosely inserting the hook provided on the hook into the groove formed on the inside of the side wall of the drain plate by means of a crank-shaped hook. Installation and removal can be done easily and efficiently.

is formed, and the rear wall 7a on the discharge port 8 side has a hook part 15 consisting of a water guide part 15a extending diagonally outward and upward from the upper end, and an engaging part 15b bent downward at right angles from the tip of the water guide part 15a. is formed over almost the entire length of the rear side wall 7a, and a water guide portion 15a is provided with mounting holes 15c at both ends thereof. On the inner surface of the front wall 7b opposite to the drain port 8 of the drain dish 7,
Hook portions 16 are provided at two locations by fixing metal plates bent into a crank shape, and a groove 16a having an open upper surface is formed by the hook portions 16 and the front wall 7b. The lower end of the hook receiving part 13 is fixed to the vertical part 1a of the notch-like recess provided in the bottom plate of the air conditioner main body 1 with a screw 18.
The upper part is bent so as to form a substantially V-shaped groove between the support part 13a and the support part 13b, which is bent forward at a right angle from the tip of the bent part 13a. The base of the hook receiving part 14 is fixed to the almost horizontal part 1b of the bottom plate with a screw 18, and the hook receiving part 14 has a horizontal V at the tip.
A support portion 14a is formed that is bent downward to form a shaped groove. The above hook receiving part 13,1
Two 4 are provided at positions corresponding to the mounting holes 15c of the hook 15 and the hook 16.

In the air conditioner of this embodiment, in order to attach the drain tray 7 to the air conditioner main body 1, hooks 15 and 16 provided on the drain tray 7 are attached to hook receiving portions 13 and 14 provided on the air conditioner main body 1. The water guide part 15a of the hook part 15 is supported by the support part 13b of the hook receiver 13, and a fastening member 12 such as a screw is inserted into one mounting hole 15c on one support part 13b.
