Description

[Detailed Description of the Invention] This invention relates to reliable treatment of condensed water that forms on the outer wall of an auxiliary drain pan during cooling operation of an air conditioner.

In an air conditioner as shown in Figure 1,
Inside it, there is a main body frame 1, a heat exchanger 2 screwed to it, a blower 3, etc., and an inlet 4.
The indoor air sucked in is cooled by a heat exchanger 2 through which cold water is passed, and then returned to the room through an outlet 5 for cooling operation. At this time, a large amount of drain is generated on the surface of the heat exchanger 2, but in order to quickly discharge it outside the machine, a main drain pan 6 is provided at the bottom of the heat exchanger 2. The drain generated in
A drain drain pipe 8 is connected to the lower drain port 7a of the auxiliary drain pan 7, which is led to the drain pan 7, and drain is discharged outside the machine.This drain discharge structure has a drain pipe connected directly to the main drain pan 6. Since the main drain pan 6 can be freely attached and detached even after the drain pipe etc. are completed, the main drain pan 6
However, since the drain pan is divided into two parts, condensation water is generated in both drain pans due to the cooling of the outer wall during drain processing, and the condensation water drips onto the floor. It was necessary to attach a heat insulating material 9 to prevent such accidents, which was extremely wasteful.Also, since the auxiliary drain pan 7 is attached to the outside of the main body frame 1, tools etc. are not needed during piping or installation work. If the insulation material 9 attached to the outside is torn or peeled off, or if the insulation material 9 is not sized or applied properly, it may get inside the auxiliary drain pan 7 and cause internal damage. There was also the problem that the drain water that had accumulated on the floor would be sucked up and drip onto the floor.

The present invention was devised to eliminate the above-mentioned conventional drawbacks, and provides a drain discharge device that can reliably dispose of dew on the outer wall without attaching any heat insulating material or the like to the outer wall.

The present invention will be described below. FIG. 3 shows an embodiment of the present invention. As shown in the figure, the shape of the auxiliary drain pan 7 is funnel-shaped.
Several vertical grooves 7b are formed on the outer periphery of the drain outlet 7a, and the connection end 8a of the drain drain pipe 8 is opened in an upwardly flaring shape as shown in FIG. FIG. 5 is a diagram in which a drain pipe 8 is connected to the auxiliary drain pan 7, and the condensed water 10 generated on the outer wall of the auxiliary drain pan 7 configured in this manner during cooling operation is transmitted through the funnel-shaped outer wall of the auxiliary drain pan 7. The drain drain pipe 8 flows in the direction of the arrow in the figure, is captured at the drain drain pipe connection end 8a, and is connected to the vertical groove 7b provided on the outer periphery of the drain drain port 7a.
and ejected from the aircraft.

As described above, the present invention has a main drain pan that receives the condensate dripping from the surface of the heat exchanger during cooling operation and guides the condensate to one place inside the machine, and a main drain pan that receives the condensate guided by the main drain pan and connects it to the lower drain port. In an air conditioner that has a drain discharge device consisting of an auxiliary drain pan that has the role of draining drain into a drain pipe, the auxiliary drain pan is shaped like a funnel, a vertical groove is provided around the outer periphery of the lower drain port, and the drain port has a drain outlet. By connecting a drain pipe with an upwardly opening opening, the condensed water that forms on the outer wall surface when draining drain can be reliably drained outside the machine without the need to attach any insulation material to the outer wall of the auxiliary drain pan. This has extremely great practical effects.
