Description

[Detailed description of the invention] "Industrial application field" The present invention relates to an integrated air conditioner, and in particular provides a structure for preventing clogging of the drainage part of the dew pan and reducing air circulation. be.

``Prior Art'' In a conventional integrated air conditioner, the inside of the main body 11 is divided into an indoor side and an outdoor side by a partition plate 14, as shown in FIG. A heat exchanger 12 and an indoor fan 15 are disposed facing each other, while an outdoor heat exchanger 13 and an outdoor fan 16 are disposed facing each other on the outdoor side.
2. A dew pan 17 is provided at the bottom of the heat exchanger 1.
The condensed water generated in step 2 is received and directed to the outside of the room. In deriving this, the dew pan 1
7 is extended rearward to form a roughly U-shaped drainage channel 18.
At the same time, the rear end is made to protrude outside from the opening formed in the partition plate 14, or, although not shown, a drainage channel is integrally formed in the fan casing that houses the indoor fan, and the front end thereof is The rear ends of the dew pans 17 are communicated with the openings of the partition plate 14, respectively. Furthermore, in order to reduce the circulation of indoor and outdoor air at the outlet of this drainage channel 18, protrusions 20 are provided at the opening of the partition plate 14 corresponding to the grooves 19 of the drainage channel 18, as shown in FIG. The gap a between the openings was made as small as possible.

``Problems to be Solved by the Invention'' However, according to such a structure, when the main body 11 is installed in a dusty area, dust entering from the outside will flow into the lower part of the partition plate 14, that is, the drainage channel 1.
Since the condensed water accumulates at the outlet part of the condensed water, the gap a is blocked and the condensed water cannot be discharged to the outside of the room.
For this reason, if the gap a is made larger, clogging with dust or the like can be prevented, but there is a drawback that the circulation of indoor and outdoor air becomes significant and the cooling effect is reduced.

"Means for solving the problem" This invention eliminates the drawbacks of the conventional type mentioned above.
A cylindrical drainage part is formed in the dew pan, and a narrow part is formed by having a bent part in the water conduit.

``Example'' The present invention will be explained using an example shown in the figure below. 1 is a main body of an integrated air conditioner, and the inside of the main body 1 is divided into an indoor side and an outdoor side by a partition plate 4. An indoor heat exchanger 2 and an indoor fan 5 are disposed facing each other on the indoor side, while an outdoor heat exchanger 3 and an outdoor fan 6 are disposed facing each other on the outdoor side. A drip tray 7 made of styrofoam or the like is installed at the bottom of the container 2, and a cylindrical drainage portion 8 protruding toward the outside of the room is integrally formed at the rear end. In addition, a narrow part 91 is formed in the conduit 9 of this drainage part 8 with a bent part in the middle, for example, it is formed in a substantially square shape as shown in FIG. 3, and the narrow part 91 is formed at the bent part. are doing.

"Function" With the above configuration, condensed water generated in the indoor heat exchanger 2 during operation of the main unit is received by the condensation tray 7 directly below it, and is led out to the outdoor side through the water conduit 9 of the drainage member 8. be done. At this time, air inside and outside the room tries to flow through the water conduit 9, but the narrow portion 91 in the water conduit 9 prevents the air from flowing. In addition, dust that has entered from outside the main body 1 may be removed from the partition plate 4.
Even if the condensed water accumulates at the lower part, that is, at the outlet of the water conduit 9, the outlet is sufficiently wide and the discharge of condensed water is not obstructed.

``Effects of the invention'' As described above, in this invention, a cylindrical drainage part is formed in the dew pan, and a narrow part is formed in the conduit with a bent part in the middle. Therefore, the outlet of the water conduit can be made sufficiently wide, and even if dust that has entered from outside the main body accumulates at the bottom of the partition plate, the water conduit 9 will not be clogged and the condensed water can be reliably led out. can. Furthermore, the narrow portion within the water conduit can prevent air from flowing inside and outside the room, as in the past, and there is no risk of deterioration in operating efficiency. Moreover, it can be implemented at low cost with an extremely simple configuration as described above.
