[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a window-type air conditioner that is mounted on the wall of a building.

[Prior art]

As a type of air conditioner, a window-type air conditioner is widely used, which is mounted on a wall window with a part of the housing exposed both indoors and outdoors.

FIG. 1 is a plan view showing the inside of a casing of a conventional air conditioner of this type. To explain this based on the figure, the casing 3 of the air conditioner 2 mounted on a wall 1 is a rectangular box. It is shaped like a roof, with approximately half of its total length exposed to the outdoors. A cooler 4 and an indoor blower fan 5 are provided inside the room of the casing 3, and a V-shaped condenser 6 and a condenser 6 directly connected to a motor 7 are provided outside the room. An outdoor ventilation fan 8 is provided. 9 is cooler 4
and a condenser 6 through piping, and the cooler 4 and condenser 6 are connected through separate piping. 10 is a dew pan, 11 is a blowout port, and 12 is a blowout nozzle. And Juan 5,
When the motor for 8 and the compressor 9 are started, the refrigerant circulating in the pipes by the compressor 9 repeats evaporation and condensation, and is sucked into the side of the casing 3 by the blower fan 5 inside the room. Indoor air sucked through the mouth is cooled by the cooler 4 and then blown out from the outlet 11 into the room. In addition, the outdoor air sucked from the suction port on the side of the housing 3 by the ventilation fan 8 outside the room is
After removing heat from the refrigerant gas passing through the condenser 6 and raising its temperature, the refrigerant gas is blown out from the blow-off nozzle 12 to the outside.

During cooling performed in this manner, the air that is blown up by the blower fan 5 and passes through the cooler 4 is cooled and condensed, and accumulates in the dew pan 10 to become drain water.
This drain water is then scattered by the blower fan 8 and used for heat radiation from the condenser 6.

However, in conventional air conditioners,
Droplets of drain water blown away by the wind pressure of the blower fan 8 are often scattered outside from the lattice part of the blow-off nozzle 12 and wet objects around the outside of the casing room, and the drain water is also wasted. There were flaws.

[Summary of the idea]

The present invention was developed in view of the above points, and consists of a plurality of annular ribs arranged concentrically within the circular air outlet of the condenser cooling fan provided inside the outdoor side of the casing. By allowing scattered drain water to adhere and flow down, and by providing a gutter that runs from the lower end of the annular rib toward the bottom of the blower fan to collect the flowing drain water, it is possible to prevent water droplets from scattering outdoors and to effectively utilize low-temperature drain water. The purpose of this project is to provide an air conditioner that measures the following. Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

An indoor ventilation fan 28 is mounted on a shaft inside the room, and is directly connected to a motor 29 and driven to rotate. The cooler 30 has a large number of fins and is housed in the indoor exposed part of the casing 24, and the part between it and the intake side of the compressor 31 provided in the center of the casing 24 is not shown. The front end surface of the housing 24 on the indoor 25 side includes a rib that blows air that has been sucked from the indoor 25 by the blower fan 28 and cooled by being blown onto the cooler 30 into the indoor 25. A blower outlet 32 is provided.

On the other hand, inside the indoor exterior of the casing 24, a multi-stage condenser 33 having a large number of fins is arranged close to both side walls of the casing 24, and one end is connected to a pipe (not shown). It is connected to the discharge side of the compressor 31. Further, the compressor 31 is connected to the cooler 30 through another pipe. The reference numeral 34 is an outdoor ventilation fan that is disposed in the middle of the condensers 33 on both sides and is directly connected to a motor 35 and driven to rotate. The air from outside 26 is sucked into the condenser 3.
After cooling the air outlet 3, the cylindrical air outlet 3 at the rear end of the housing 24
It is configured to blow out from 7.

Refrigerant gas compressed and frozen by the compressor 31 is circulated within the pipe, and evaporation by the cooler 30 and condensation by the condenser 33 are repeated. What is designated by the reference numeral 38 is a dew tray that collects drain water generated when indoor air flowing from the blower fan 28 toward the outlet 32 is cooled by the cooler 30, and is provided below the cooler 30. , the drain pipe 39 connected to this dew pan 38 is connected to the dew pan 3
It is opened above the base plate 40 outside the room, which is lower than the height of 8, that is, below the blower fan 28, so that drain water is discharged onto the base plate 40. Further, the outdoor blower fan 34 is provided with a water ring 41 integrally with the blade, and its rotation causes the drain water on the base plate 40 to be swung around and scattered to the condenser 33 to cool it.
