Abstract

PURPOSE:To reduce the pressure loss due to bent air duct and contrive to increase the air flow rate and to lower the noise by a structure wherein a cold air discharge port is enlarged to the side surface in the window air conditioner having an indoor blowing structure with horizontally circulating system. CONSTITUTION:The window air conditioner having an indoor blowing structure with horizontally circulating system sucks indoor air from a suction grill so as to pass through a filter 3, cool at an evaporator 4, accelerate by means of a Sirroco fan 6 and discharge through the bent air duct 9 from a discharge port 2. In this case, the discharge port 2 is enlarged to the side surface to make an L- shape structure. Due to the structure as mentioned above, the cold air accelerated by means of the Sirroco fan 6 is blown-off from the discharge port 2 into a room smoothly without changing its flow direction, resulting in decreasing the draft resistance in the bent air duct 9 and accomplishing the increase of air flow rate, the lowering of the noise and the like.

欠点があった。The indoor air blowing structure of a conventional window type air conditioner will be explained with reference to FIGS. 1, 2, and 3. Air sucked in by the suction grill 1 passes through a filter 3, is cooled by an evaporator 4, and is accelerated by a sirocco fan 6. The cold air with increased wind speed passes through the wind path 9 and reaches the outlet cross section S1.
It blows out into the room from the discharge port 2 having a diameter. Here, the discharged air blown out from the sirocco fan with a high wind speed is forced to bend the flow direction in the bending air passage 4, which has the disadvantage of increasing ventilation resistance, reducing the air volume, and increasing noise. Ta.

可能となる。As shown in FIG. 4, by enlarging the discharge port 2 to the side and increasing the opening area to 82, the air discharged from the white/bottom fan is blown toward the indoor side without changing the direction of the flow. Therefore, the pressure loss at the bending portion of the airflow is reduced, and it becomes possible to increase the air volume and reduce noise.

来る。Embodiments of the present invention will be described with reference to FIGS. 4, 5, and 6. Indoor air sucked through a suction grill 1 passes through a filter 3, is cooled by an evaporator 2, and is accelerated by a sirocco fan 6. And the cold air with increased wind speed,
As shown by the arrow in the figure, the L-shaped discharge port 2 (opening area S2) smoothly expands to the side without changing the flow direction.
Since more air is blown into the room, the ventilation resistance in the curved air passage 9 is reduced, the air volume is increased, and noise can be reduced.
