The present invention relates to a window-type room air conditioner, and more particularly, to a window-type room air conditioner that can prevent heat loss due to load to increase heat exchange efficiency and maximize cooling efficiency.

The window-type room air conditioner that cools the room by performing pressure, evaporation, and mechanically compresses the refrigerant gas through 4 processes of compression, condensation, expansion, and evaporation. The indoor and outdoor units are installed in the front and back of the main body. In such a window-type room air conditioner, an indoor unit in which an evaporator is built and an outdoor unit in which a condenser is built are generally separated in front and rear of the main body, and a blower fan and a propeller fan are built in front and rear between the indoor and the outdoor unit. The driving motor is installed to cool the indoors by performing heat exchange while sucking and discharging indoor and outdoor air with the heat exchanger.

By the way, the conventional window-type room air conditioner has a suction port for suctioning the indoor air to the evaporator side, the discharge port for discharging the low-temperature air heat-exchanged from the evaporator back to the room on the upper side or one side of the same inlet As it is provided, the indoor air to be sucked and the low-temperature air discharged close to each other, thereby causing a backflow phenomenon in which the low-temperature air flows back into the suction port, thereby reducing heat exchange efficiency and cooling efficiency.

And the blower fan is installed at the rear of the evaporator so that the duct for guiding the discharge and the suction of indoor air is installed so as to intersect the blower fan's rotation direction and the discharge direction at right angles. Only the top, bottom, left and right could be adjusted, so there was a defect that the cold wind could not be supplied in a balanced manner.

In addition, one propeller fan installed in front of the condenser has a low heat exchange efficiency compared to the heat dissipation area of the condenser, so that the heat exchange efficiency of the condenser is lowered. Air deteriorated the surrounding environment, and the compressor and the driving motor mounted to the indoor unit had a defect that caused severe vibration and noise.

The present invention has been made in view of the above-mentioned conventional defects, and its object is to prevent the loss of blowing force due to the load to increase the heat exchange efficiency and to maximize the cooling efficiency of the window-type room air conditioner. In providing.

This object of the present invention is achieved by providing a window-type room air conditioner that bisects the heat exchanger and separates the air flow passage. The window-type room air conditioner forms an indoor air inlet on both side walls of the indoor unit, and discharges are provided on both sides of the front lower part. It has a discharge port on both side walls of the outdoor unit, constitutes an outdoor air intake frame at the rear side, bisects and installs the evaporator and blower fan toward the inlet of the indoor unit, and bisects the propagator and the propeller fan toward the outlet of the outdoor unit. It is characterized by being.

Hereinafter, the configuration of an embodiment of the present invention with reference to the accompanying drawings in detail as follows.

It is imperative.

Here, the blower fan 56 is embedded in a duct 57 for guiding airflow so as to directly discharge the sucked indoor air to the lower portion of the rotational direction. The duct 57 is blower fan as shown in FIG. A blower chamber 57A for accommodating 56 is provided in the upper center and is configured such that the discharge port 57B, which is curvedly communicated downward in the blower fan rotation direction, is opened to one side, and the discharge port 57B of the duct 57. The front surface is provided with a wind direction control mechanism 52A to be supported by the main body to adjust the wind direction from side to side.

Thus, the partition 58 is formed in the rear surface of the duct 57 in which the blower fan 56 is built, so that the 1st indoor chamber 5 and the 2nd indoor chamber 5A may be isolate | separated, respectively.

The first and second outdoor units 6 and 6A first have discharge ports 61 formed on both side walls of the rear end of the main body, and the outdoor air inlet 62 between the center of the rear of the main body, that is, between the first and second outdoor units. The condenser 63 is mounted inside the two suction ports 61 at the height of the main body, and has a blower port 64A in line with the partition walls 58 of the first and second indoor rooms. The partition 64 which separates in the full length width is provided, and the blower opening 64A is constructed with the propeller fan 65 mentioned later, and isolate | separates the 1st, 2nd outdoor unit 6 and 6A, respectively.

And wrapped between the first and second outdoor unit (6) (6A), that is, the front center of the outdoor air inlet (6) wrapped in the support 31 toward both the first and second outdoor unit (6) (6A) The power transmission means 7 is provided with a driving motor 3 which is configured to deliver the rotational force to the first and second indoor and outdoor air sides from the rotary shaft which has been driven from the drive motor 3 and drawn out from both sides of the rotation motor. The transmission means (7) is provided with a pulley (72) at a predetermined position of the outdoor shaft side rotation shaft (71) directly drawn out from the drive motor (3), and the propeller fan (65) is provided at the end of the rotation shaft (71). It is built up.

In addition, as shown in FIG. 3, the center of the first and second indoor units 5 and 5A is provided with a rotating shaft 73 having pulleys 71 on both sides at the same interval as the pulley on the driving motor rotation side, and the outdoor unit side. It is connected to the pulley 72 and the belt 75, the center of the rotary shaft 73 is fitted to the bush (76A), and freely pivoted on the support 76, the support 76, the control unit (8) It is fixedly installed at the upper portion of the rotary shaft 73, both ends of the blower fan 56 of the first and the second indoor unit is built up.

And a compression chamber 4A in which the first chamber 5 and the partition walls 58 and 64 of the first outdoor unit 6 are connected by the auxiliary partition walls 59 in the longitudinal direction to install the compressor 4 therein. Compression chamber 4A provided with a compressor 4 connected by the auxiliary partition wall 59 is provided, and a vibration damping plate 41 is attached to the inner surface of the auxiliary partition wall 59 so that the first and second outdoor units ( 6) (6A) The vibration isolation plate 32 is also attached to the inner surface of the central partition wall to provide the driving chamber 3A.

When the combined window type air conditioner is operated as described above, the refrigerant gas is condenser 63 of the first and second outdoor units 6 and 6A and the evaporator 55 of the first and second indoor units 5 and 5A. ), While the pressure control and the vaporization control are mechanically performed as usual while the drive motor 3 is operated to rotate the outdoor shaft side rotation shaft 71, the belt 75 connected to the pulley 78 of the rotation shaft is rotated. The indoor unit side rotation shaft 73 is rotated together by the driving.

At this time, the indoor external side rotation shaft rotates the propeller fan 65 and the blower fan 56 at the same time to achieve heat exchange while sucking and discharging indoor and outdoor air.

In more detail, first, the propeller fan 65 of the first and second outdoor units sucks outdoor air to the inlet port 62 at the rear center of the main body and blows the air to the condenser 63 for heat exchange to the discharge port 61. Discharge, and the first one. 2 The blower fan 56 of the indoor unit sucks indoor air into the inlet port 53 formed at both ends of the main body to form heat exchange from the evaporator 55, and then guides the cold air to the duct 57 so that the front plate 51 Is discharged to the discharge port 52.

The cold air discharged at this time can be adjusted to the left and right of the wind direction control port 52A by the selective adjustment of the wind direction control switch 52A-1 at the center of the front plate 51, and also by the guide vane of the discharge port 52. It is possible to adjust up and down.

The indoor air sucked into the center of the rear of the main body not only increases the heat exchange efficiency of the condenser by distributing and discharging the hot air heat-exchanged to both sides in a well-balanced manner in the entire heat dissipation area of the divided first and second outdoor units.
