Description

Window air conditioner

The present invention relates to a window-type air conditioner, and more particularly, to a window-type air conditioner having a condenser formed on an outdoor space of a window-type air conditioner body to increase condensation efficiency by blowing a large amount of wind toward the condenser at high speed. will be.

In general, a window-type air conditioner is installed in a window or the like, as shown in FIG. 1, and includes a main body 1 having the front and the rear exposed to the inside and the outside, and inside the main body 1 by a diaphragm 2. 10) and the outdoor space (9) and the diaphragm (2) is provided with a motor (3) for transmitting the rotational force in both directions from the center.

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 to condense the condenser 5. Air-cool). In addition, the outdoor suction port 9b is formed at both side plates of the outdoor space part 9, and the outdoor discharge port 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 opening 9b and air cooled by passing through the rear condenser 6, and the air heated by heat exchange at the time of air cooling. 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 9b and then passes through the rear condenser 5. 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 into the room through the indoor discharge port (10a) and the room is cooled.

However, the conventional window air conditioner as described above has a problem in that when the cooling fan at the rear of the motor rotates at a high speed in order to increase the heat dissipation effect of the condenser, the circulation fan of the indoor space is rotated at the same time to generate noise in the room.

The present invention was created in view of the above problems, and provided with a speed increasing means at the rear of the condenser formed in the outdoor space of the window type air conditioner main body to blow a large amount of wind toward the condenser at high speed to increase the condensation efficiency The purpose is to provide.
