In addition, a compressor (4) for compressing the refrigerant at a high temperature and high pressure is installed in the outdoor space (9), and a condenser (5) condensing the refrigerant compressed at high temperature and high pressure in the compressor (4) at the rear of the condenser at room temperature. Is installed.

The condenser 5 has a plurality of coolant tubes 5a through which the coolant flows, and is arranged in a zigzag form, and the heat dissipation fins 5b are provided on the outer circumferential surface of each coolant tube 5a to radiate heat generated from them to the outside.

In addition, a cooling fan 6 is installed on the rotating shaft 3a formed in the motor 3 at the rear of the motor 3 corresponding to the outdoor space 9, and blows wind toward the condenser 5 so that the condenser ( Air cool 5). In addition, outdoor suction openings (not shown) are formed at both side plates of the outdoor space portion 9, and an outdoor discharge opening 9a is formed at the rear of the condenser 5.

Therefore, when the cooling fan 6 is rotated by the driving of the motor 3, the outdoor air is sucked along the outdoor suction port (not shown), and the air is cooled by passing through the condenser 6 at the rear, and heated by heat exchange during air cooling. The air is configured to be discharged to the outside along the outdoor discharge port 9a.

On the other hand, the evaporator 7 is installed inside the indoor space 10. The evaporator 7 is an expanded refrigerant flows therein through a capillary tube (not shown), and absorbs ambient heat in the process of evaporating the liquid refrigerant in the refrigerant, thus lowering the room temperature.

The circulation fan 8 is installed in the indoor space 10 corresponding to the motor 3. The circulation fan (8) is rotated by the motor (3), which transmits rotational force in both directions, to circulate the indoor air toward the evaporator (7).

That is, the indoor air inlet 10b through which the indoor air is sucked toward the evaporator 7 by the rotation of the circulation fan 8 is installed, and the cold air cooled by heat exchange while passing through the evaporator 7 behind the indoor air inlet 10b is installed. An indoor discharge port 10a discharged to the room is formed.

In the conventional window type air conditioner configured as described above, when the motor 3 is operated, the circulation fan 8 and the cooling fan 6 installed by being fitted to the rotation shaft 3a in both directions thereof rotate simultaneously. In addition, when the refrigerant is compressed to a high temperature and high pressure in the compressor 4 and then circulated toward the condenser 5, the refrigerant is air-cooled by the wind generated by the rotation of the cooling fan 6.

That is, when the cooling fan 6 is rotated, the outdoor air is sucked into the outdoor space 9 through the outdoor suction port (not shown), and then passes through the condenser 5 at the rear. At this time, while the strong wind passes through the condenser 5, the heat of the condenser 5 is radiated to the outside to cool the wind is discharged to the outside along the outdoor discharge port (9a).

In addition, the refrigerant condensed at low temperature and low pressure in the condenser 5 is expanded while passing through a capillary tube (not shown), and thus the expanded gas liquid mixed refrigerant is circulated toward the evaporator 7 of the indoor space 10 to provide a double liquid state. The refrigerant of evaporates to absorb external heat.

Therefore, when the circulation fan 8 is rotated by the driving of the motor 3, the indoor air is sucked into the indoor space 10 along the indoor suction port 10b and then cooled while passing through the evaporator 7. In addition, the cooled indoor air is discharged again to the room through the indoor discharge port (10a) is to cool the room cool.

This conventional window air conditioner has a problem that can not effectively process the condensate generated in the heat exchange process of the evaporator.

In addition, there is another problem that it is difficult to expect an increase in the condensation efficiency by blowing air using only a cooling fan formed in front of the heat to dissipate heat generated in the condenser.

The present invention was created in view of the above problems, and condensate cooling of the window type air conditioner that uses condensate effectively by sprinkling the condensate generated during the heat exchange process of the evaporator to the top of the condenser in the outdoor space, and improves the cooling efficiency of the condenser. The object is to provide a device.

Referring to the operation of one embodiment of the present invention configured as described above in detail.

First, when cooling is started and the motor 50 is driven, the circulation fan 52 and the cooling fan 51 installed in both directions rotate and the compressor 30 is operated.

In the compressor 30, the refrigerant is compressed to high temperature and high pressure, and then circulated toward the condenser 40. The outdoor air is blown by the rotation of the cooling fan 51 to cool the condenser 40.

On the other hand, the indoor air is sucked into the indoor space 22 along the indoor suction port 24 by the rotation of the circulation fan 52, cooled after passing through the evaporator 70 in the rear, and the cooled indoor air Is discharged into the room through the indoor discharge port 25 is to cool the room.

At this time, the evaporator 70 is converted into a high temperature by absorbing the external heat while the liquid refrigerant circulated therein evaporates, a large amount of condensed water is generated in this heat exchange process.

At this time, when the condensed water is collected by falling to the first drip unit 80 directly below the evaporator 70, the pump 90b is operated in accordance with the driving of the motor 90a of the first pumping means (90). By the hose 81, the condensed water is introduced into the watering means 60 of the upper end of the condenser 40 of the outdoor space 23.

Therefore, the condensed water collected in the sprinkling tank 61 of the sprinkling means 60 is evenly sprayed on the surface of the condenser 40 through the nozzle 62 of the bottom face.

At this time, the cooling fan 51 in front of the condenser 40 is also rotated together so that the air-cooling and water-cooling functions are performed at the same time, thereby rapidly dissipating high heat generated in the condenser 40, thereby increasing condensation efficiency.

In addition, the condensed water passing through the condenser 40 is collected in the second drip tray 82 at the bottom thereof, wherein the condensed water is heat-exchanged by passing through the surface of the high-temperature condenser 40 so that its temperature is raised. Stored.

Therefore, when the condensed water is sprinkled again to the surface of the condenser 40, a predetermined cooling effect cannot be obtained. On the other hand, a cooling effect can be expected when the condensed water is dropped at a predetermined height on the top of the condenser 40. This configuration is impossible due to the internal space structure of the window type air conditioner body 10.

Therefore, the condensed water introduced into the second drip tray 82 is supplied back to the first drip tray 80 through the second pumping means 91. At this time, the pump 91b is operated according to the driving of the motor 91a of the second pumping means 91 so that the condensed water is introduced through the hose 81.

Thereafter, the condensed water supplied to the first drip unit 80 is mixed with the condensed water falling from the surface of the evaporator 70, while the condensed water is converted to a low temperature in the indoor space 22 to transfer the first pumping means 90. Through the watering means 60 is supplied again.

In the process as described above, the loss of minute cold air is expected, but the cooling efficiency is increased by spraying condensate of low temperature in the condenser 40, resulting in an increase in the cooling efficiency of the overall air conditioner. .

Therefore, the refrigerant liquefied and condensed at low temperature and low pressure inside the condenser 40 expands through a capillary tube (not shown), and then the expanded gas liquid mixed refrigerant is returned to the evaporator 70 of the indoor space 22. The room is cooled by repeatedly performing a series of cooling functions.

The present invention is not limited to the contents described in the embodiment, it is intended to include all modifications, variations and improvements included in the contents of the utility model registration claims without departing from the spirit and principles of the present invention.

As described above, the present invention sprays the condensate generated during the heat exchange process of the evaporator to the top of the condenser in the outdoor space, thereby effectively utilizing the condensate and improving the cooling efficiency of the condenser, thereby increasing the overall cooling efficiency of the air conditioner. .
