Abstract

PURPOSE:To contrive to increase the heat exchanging rate in the titled air conditioner, by dripping drainage from a plurality of through-holes provided on a drain pipe to the surface of the fin of a condenser in the wide range. CONSTITUTION:When a compressor 7 and a fan motor 8 are operated, a room is cooled in such a manner that heat is radiated by an outdoor compressor 14, while it is absorbed by an indoor evaporator 11. At that time, the vapor in the air on the indoor side is liquified and is collected in a drain pan 12 drainage, flowing into a drain pipe 15, passing through a tube 13. The drainage flowing into the drain pipe 15 drips from through-holes 15a opened on the drain pipe 15 along the surface of a fin 16. Because the through-holes opened in the lower- most part of a drain pipe 15 are made smaller than the other holes, the drainage drips in the wide area of a fin 16 from three-staged holes in nearly the same quantity, so that the fin 16 can be cooled sufficiently.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an air conditioner in which indoor and outdoor areas are integrated.
The present invention relates to a drain water treatment device that uses drain water from an evaporator for heat exchange.

Structure of the conventional example and its problems The drain processing structure in the conventional integrated air conditioner is as shown in Fig. A structure is known in which the condenser C is extended to the side of the condenser C, and is connected to a condenser C that has approximately the same width as the condenser C.

With this structure, by driving the fan motor e and the compressor f, air is blown by the indoor fan g and the outdoor fan h, heat is absorbed by the evaporator a, and heat is radiated by the condenser. At this time, the air passing through the evaporator a'1 is cooled, and the water vapor contained in the air is liquefied and becomes dew, which drips onto the drain pan.

The dripped drain water collects in a drain provided in contact with the condenser C from the drain outlet of the drain dish, and flows down the surface of the condenser C to the substrate.

At this time, since the drain water generated in the evaporator a is cooled, when the entire surface of the condenser C falls off, it helps the condensation action of the condenser C, but the fins of the fin-tube condenser C There was a drawback that the temperature difference between the condenser C and the drain could not be used effectively because only the ends were covered with gold.

OBJECT OF THE INVENTION The present invention solves these problems, and provides a drain water system in which drain water flows down completely on the fin surface of a fin-tube type condenser, effectively utilizing the temperature difference between the drain water and the condenser. The purpose is to obtain a processing device.

Structure of the Invention In order to achieve all of these objects, the present invention provides a drain pipe having a large number of through holes inside the fin tube type condenser and passing through the entire condenser. One end of this drain pipe is a reed tube with a drain water introduction path, and the other end of the drain pipe is closed off.

With this configuration, the drain water produced in the evaporator is allowed to flow widely through the introduction path, through the holes in the drain pipe provided inside the condenser, and onto the fin surface of the condenser.

DESCRIPTION OF THE EMBODIMENTS The present invention will now be described with reference to FIGS. 1 to 6 of the accompanying drawings, which illustrate one embodiment of the present invention.

In the figure, 1 is the main body of the indoor/outdoor integrated air conditioner;
The front side has an indoor air inlet 2 and an outlet 3,
There are all outdoor air inlets 4 at the rear side of the house, and an external heat exchange air outlet 5 at the rear of the reed. Reference numeral 6 denotes a partition plate that divides the inside of the main body 1 into an inner side and an outer side. 7 is a compressor provided in the main body 1, 8 is a fan motor,
An outdoor fan 9 is provided at one end of the rotating shaft, and an indoor fan 10 is provided at the other end. 11 is an evaporator provided opposite to the indoor air suction port 2; 12 is a drain tray provided below the evaporator 11; A tube 13 for introducing drain water is connected to the outlet of the drain dish 12. 14 is a condenser, and a drain pipe 15 passing through the condenser 14 and having porous holes 15a is provided inside the condenser.

One end of this drain pipe 16 is connected to the tube 13, and the other end is closed. In addition, the drain pipe 16
Among the through holes 15L formed in the bottom, the one at the bottom has a small diameter, and the ones on the left and right of the through holes are formed with slightly larger diameters. The upper half of the fin 16 that contacts the drain pipe 15 is subjected to a drawing process of 91γ, and is in wide contact with the pipe 16. On the other hand, the lower half of the fin 16 does not have a restriction and is perpendicular to the three holes of the drain nozzle 160.
Protrusions 18 are provided near each of the three through holes 152L, and these protrusions 18 maintain uniform spacing between the fins 16. 19 is refrigerant ζ
This is the hole through which Eve 2o passes.

In the above structure, when the compressor 7 and fan motor 8 are operated, heat is radiated in the condenser 14 on the outdoor side, and heat is absorbed in the evaporator 11 on the indoor side, thereby completely cooling the room. At this time, the water vapor in the air on the indoor side is liquefied and becomes drain water, which accumulates on the drain pan 12 and passes through the tube 13 to the drain pipe 1.
5.

The inflowing drain water is drained into the drain pipe 15;'t
J! Flows down the surface of hole 16a X-57in16.

At this time, since the through hole drilled at the bottom of the drain pipe 16 is smaller than the other holes, the drain water flows down from the three holes in approximately equal amounts over a wide area of the fins 16, sufficiently cooling the fins 16. .

one! Since the pipe 15 is cooled by the drain water, the upper fins of the pipe 16 are also cooled through all the constricted portions 17 of the fins 16 that are in close contact with the upper half of the pipe 15. These cooling effects greatly enhance the condensing effect of the condenser at low cost.

Effects of the Invention As described above, in the drain water treatment device of the present invention, the drain water generated in the evaporator is transmitted to the fin surface and flows down through the through hole of the drain squib that passes through the condenser and is closed at the other end. The drain water introduced into the drain pipe cools the drain pipe and the fins in contact with the drain pipe, and the drain water flows down the entire surface of the fin from the through hole of the pipe, which efficiently cools the fin and cools the condenser pipe. This has the effect of greatly promoting the condensation effect of the liquid at a low cost.
