Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an air conditioner, particularly a drain treatment for an air conditioner having a structure in which drain water generated in an evaporator is scattered to a condenser using a rotating disk. Regarding equipment.

[Technical background and problems of the invention]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An air conditioner equipped with a conventional drain treatment device that uses a rotating disk to scatter drain water will be described with reference to FIGS. 4 and 5.

FIG. 4 shows the external appearance of a vertically elongated window-type air conditioner main body 1, which is provided with an indoor unit part 2 and an outdoor unit part 3 inside. The front surface of the main body 1 includes an air inlet 4 and an air outlet 5 on the indoor side, and an evaporator and an indoor blower (both not shown) are arranged in the ventilation path inside the air inlet 4 and air outlet 5.

Further, FIG. 5 shows the outdoor side unit part which constitutes the rear part and bottom part in the main body 1 with a cross-sectional structure taken along the line A-A of the main body 1. In this figure, 6 is an air inlet on the outdoor side formed on the rear surface of the main body 1, and 7 is an air outlet on the outdoor side. A ventilation passage 9 partitioned off by a fan casing 8 is provided in the housing communicating with the air inlet 6 and the air outlet 7.
In this ventilation passage 9, a condenser 10 is installed at the air suction port 6, and a cross-flow type blower 11 is installed between the condenser 10 and the air outlet 7 in the longitudinal direction. It is set up. Furthermore, this condenser 10
A rotating disk 13 is provided on the bottom plate 12 on the downstream side of the ventilation passage for splashing up and scattering drain water stored on the bottom plate 12 to the condenser 10. 14 is a motor for rotating this rotary disk 13;
5 is a compressor placed on the bottom plate 12.

To explain the operation of the air conditioner with the above configuration,
By operating the compressor 15, the condenser 10 performs a heat dissipation action, and the evaporator (not shown) performs a cooling action. Therefore, there is an indoor fan (not shown) in the room.
Cooled and dehumidified air is sent out for cooling. Further, the drain water generated in this evaporator is guided to the bottom plate 12 of the outdoor unit part 3, and the condenser 10 is guided by the rotating disk 13 disposed on the bottom plate 12.
It is scattered and evaporated, and is exhausted to the outside from the air outlet 7 along with the high temperature air communicated with the condenser 10 by the outdoor side blower 11.

By the way, in the above-described air conditioner, the condenser 10 is located on the air intake side of the ventilation passage 9, and the rotating disk 13 scatters drain water to the condenser 10 from its leeward side.

For this reason, the splashed drain water becomes weaker as it goes farther away, and is sucked toward the blower 11, so that the drain water does not reach the surface of the condenser 10 near the blower 11, but directly to the blower. The water is guided in the direction of water droplets 11, and is further discharged as water droplets from the air outlet 7 by the blower 11. For this reason, there was a problem that the air outlet 7 portion was flooded with water and that the drain water did not contribute to improving the condensing capacity, making it impossible to improve the condensing capacity.

[Purpose of invention]

The present invention was developed in consideration of the above circumstances, and aims to provide a drain treatment device for an air conditioner that effectively scatters drain water into a condenser and does not allow water droplets to blow out of the main unit. shall be.

[Summary of the idea]

In order to achieve the above object, the present invention has a protruding water plate that applies splashed water from the rotating disk to the surface of the condenser between the rotating disk and the outdoor fan. This prevents the splashed water from being led directly to the blower and improves the condensing capacity of the condenser.

[Example of idea]

The following is an example of the present invention shown in Figures 1 to 3.
This will be explained with reference to the figures. Note that the parts that are substantially the same as those described in FIGS. 4 and 5 are designated by the same numbers, and the description thereof will be omitted. In FIG. 1 or 2, the bottom plate 12 of the outdoor unit part 3
A condenser 10 and an outdoor blower 11 are arranged vertically above the condenser 10, and in a portion located between the blower 11 and the rotating disk 13 for splashing drain water on the leeward surface of the condenser 10, A water patch plate 16 is formed in the longitudinal direction to which water splashed by the rotating disk 13 is applied. The configuration of this water patch plate 16 is as shown in FIG.
7. A pair of locking pieces 18 , 18 are provided above and below the water patch part 17 to be held between parts of the pipes arranged in the vertical direction of the condenser 10 , and the water patch part 17
guide protrusion 1 that slopes downward toward the condenser 10 side so that water droplets applied to the surface of the guide stream flow down toward the condenser 10 side;
9... (or guide groove) is formed.

The water patch plate 16 having the above structure is fitted and locked onto the pipe of the condenser 10 so as to be located at the part of the surface of the condenser 10 that is hit by the water splashed by the rotating disk 13.

Next, the operation of the air conditioner having the above configuration will be explained.

First, by operating the compressor 15, drain water generated in an evaporator (not shown) is guided to the bottom plate 12 of the outdoor unit section 3. The drain water stored in the rotating disk 13 is splashed onto the surface of the condenser 10, and the splashed drain water is directly applied to the surface of the condenser 10 on the side closer to the rotating disk 13, thereby performing heat exchange. . In addition, since the force of scattering is reduced on the surface of the condenser 10 on the side closer to the blower 11, it is attracted to the blower 11 side and is no longer directly applied to the surface of the condenser 10.
It hits the surface and becomes water droplets.

The water droplets applied to the water application plate 16 are guided to the condenser 10 via the guide projections 19 (or guide grooves), where heat exchange takes place. Therefore, the drain water splashed up by the rotating disk 13 is transferred to the blower 1.
All of it can be guided to the surface of the condenser 10 without being directly sucked into the condenser 1.

[Effect of idea]

As described above, the present invention includes a water plate on the surface of the condenser located between the rotating disk and the blower to prevent the drain water splashed up by the rotating disk from being directly sucked into the blower. This prevents water droplets from scattering from the outdoor outlet, preventing the area near the outlet from becoming soaked with water, and all of the drain water is effectively guided to the condenser, making the heat of evaporation of the drain water effective. It can be used to improve condensation ability.
