[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage device for an air conditioner.

[0002]

2. Description of the Related Art In recent years, an air conditioner is generally shown in FIG. 5 in which the mainstream has shifted from a floor-standing type to a ceiling type.

A conventional drainage device for an air conditioner is disclosed in Japanese Patent Application Laid-Open No. 61-189079.

A conventional drainage device for an air conditioner will be described below with reference to the drawings. FIG. 5 is a cross-sectional view of a conventional air conditioner body. In FIG. 5, 1 is an outer casing of the air conditioner, 2 is a decorative panel, and 3 is an indoor heat exchanger. Reference numeral 4 is a drain pan for storing the dew condensation water dehumidified by the indoor heat exchanger 3, and 5 is a drain pump for discharging the accumulated condensation water. Reference numeral 6 is a drain hole provided for draining condensed water temporarily accumulated on the upper portion of the drain pan 4 for repairing the drain pump 5 or the like when the drain pump 5 fails, and 7 is the drain hole 6 The head 7a is exposed so that the attachment / detachment work can be easily performed with a plug that is a piping screw for closing the. The plug 7 will be described in detail with reference to FIG. FIG. 6 is a detailed view of the drain hole 6, and 8 is a drain sheet on the drain pan 4,
Reference numeral 9 is dew condensation water that collects on the upper part. Reference numeral 10 denotes a socket bonded to the drain sheet 8, and the plug 7 is inserted into the socket 10 so that the condensed water 9 does not leak.

The operation of the drainage device of the air conditioner configured as described above will be described below.

First, when the drain pump 5 or the like fails,
In order to repair the drain pump 5, it is necessary to temporarily discharge the condensed water 9 accumulated on the upper portion of the drain pan 4. Next, the plug 7 is taken out from the socket 10, and the condensed water 9 is discharged through the drain hole 6.

[0007]

However, in the above-mentioned conventional configuration, since the plug 7 is a pipe screw,
For removal and installation, the plug 7 must be rotated several times in the ceiling, which is troublesome. Also, plug 7
Plug 7 and socket 10 when you are about to remove
Water leaks from the gap. Furthermore, by removing the plug 7 from the socket 10, the plug 7
Had the drawback of losing.

It is a first object of the present invention to provide a drainage device for an air conditioner which does not need to be removed and can be drained in one operation and does not leak.

Further, the above-mentioned conventional structure has a drawback that the head 7a of the plug 7 projects from the lower surface of the drain pan 4 because the plug 7 is screwed to the socket 10.

A second object of the present invention is to provide a drainage device for an air conditioner which does not protrude from the lower surface of the drain pan.

[0011]

In order to achieve the first object, a drainage device for an air conditioner according to the present invention comprises a tubular portion and a supporter formed in a spherical shape at the tip of the tubular portion. The supporter is slidably held in the drain hole of the drain pan, and when the tubular portion is slid so as to be substantially vertical,
The drain hole of the drain pan is closed by the supporter when the drain hole of the drain pan communicates with the inside of the tubular portion through the hole of the supporter and the tubular portion is slid so as to incline in the lateral direction. It is configured like this.

Further, in order to achieve the second object, the drainage device for an air conditioner of the present invention is further configured such that the cylindrical portion is housed in the recess formed in the lower surface of the drain pan. ..

[0013]

In the drainage device of the air conditioner of the present invention, the supporter is slidably held in the drain hole of the drain pan, and when the tubular portion is slid so as to be in a substantially vertical direction, the supporter passes through the hole of the supporter. The drain hole of the drain pan communicates with the inside of the tube, and when the tube is slid horizontally, the drain hole of the drain pan is closed by the supporter. The operation is one action. By connecting the hose to the lower part of the tubular portion, there is no fear of water leakage during drainage operation. Further, since this drainage device is embedded and fitted in the drain pan, there is no risk of loss.

Further, the drainage device of the air conditioner of the present invention comprises:
By accommodating the tubular portion in the recess formed on the lower surface of the drain pan, it is prevented from protruding from the lower surface of the drain pan.
