Description

Window air conditioner

The present invention relates to a window-type air conditioner, and more particularly, to a window-type air conditioner provided with a blowing member at the rear of the condenser installed in the outdoor space of the window-type air conditioner body to prevent the occurrence of a non-air blast zone on the surface of the condenser to increase the heat radiation effect. It is about.

In general, the air conditioner is installed in a window or the like as shown in Figure 1 is provided with a main body 1, the front, the rear is exposed to the interior, the outside, the interior space portion (2) by the diaphragm (2) inside the main body (1); 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) is installed at the rear thereof to liquefy the refrigerant compressed at high temperature and high pressure in the compressor (4). do. The condenser 5 has a plurality of coolant tubes 5a through which the coolant flows and is arranged in a zigzag form, and is provided with heat dissipation fins 5b on the outer circumferential surface of each coolant tube 5a for radiating heat generated from them to the outside.

In addition, a cooling fan 6 is formed on the rotating shaft 3a formed on the motor 3 at the rear of the motor 3 corresponding to the outdoor space 9 so as to blow 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 while passing through the rear condenser 5. Meanwhile, the outdoor air cooled by air is discharged to the outside along the outdoor discharge port 9a.

In addition, an evaporator 7 is installed inside the indoor space 10. The evaporator 7 is an expanded refrigerant flows through a capillary tube (not shown) therein, and absorbs ambient heat to evaporate the refrigerant, and lowers the room temperature in the process of evaporating the refrigerant. The circulation fan 8 is installed in front of the motor 3 corresponding to the indoor space 10.

The circulation fan 8 is rotated by the motor 3 which rotates in both directions to circulate the indoor air toward the evaporator 7. In addition, the indoor suction port 10b is installed in the front of the main body 1 by the rotation of the circulation fan 8 to suck the indoor air toward the evaporator 7, while passing through the evaporator 7 under the indoor suction port 10b. An indoor discharge port 10a through which the cool air cooled by heat exchange is discharged to the room is formed.

In the conventional air conditioner configured as described above, when the motor 3 is operated, the circulation fan 8 and the cooling fan 6 installed and 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 strong wind passes through the condenser 5, the heat of the condenser 5 itself is radiated to the outside and cooled, and then 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) is to cool the room cool.

At this time, a strong wind is supplied to the condenser 5 through the cooling fan 6 to radiate heat generated in the refrigerant condensation process of the condenser 5 to the outside, which will be described in more detail with reference to FIG. 2. .

2 is a view showing the strength of the cooling fan wind speed of the conventional window air conditioner, the cooling fan 6 rotated by the motor 3 is a strong wind is blown around the rotation axis (3a) around the center It can be seen that a weak wind blows due to the formation of a windless zone.

Therefore, the surface of the condenser 5 is not evenly dissipated by the strength of the wind speed, and in particular, a very slight wind is blown through the central portion, so that the heat dissipation effect is almost absent at the central portion of the condenser 5.

As described above, in the condenser of the conventional air conditioner, the intensity of the wind blown from the cooling fan varies depending on each part of the condenser, so that the distribution of condensation efficiency is uneven. As the wind is blown, the heat dissipation effect of the condenser is lowered, and consequently, the condensation efficiency is lowered.

The present invention was created in view of the above problems, and provided with a blowing member at the rear of the condenser installed in the outdoor space of the window air conditioner main body to prevent the occurrence of a non-air dead zone on the surface of the condenser to increase the heat dissipation effect The purpose is to provide.
