BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner.

[0002]

2. Description of the Related Art FIG. 2 is a longitudinal sectional view of a conventional wall-mounted air conditioner. In FIG. 2, reference numeral 1 denotes an air conditioner main body, 3 denotes a heat exchanger which is disposed inside the main body 1 and extends vertically, and 4 denotes a through flow which is disposed below a downstream side of the heat exchanger 3 and extends substantially horizontally. Fan 2, 2 is disposed on the upstream side of the heat exchanger 3, has a front panel having a suction port 9, 5 is an outlet formed in the lower part of the front of the main body 1, 6 is an outlet provided in the outlet 5. A drain pan 7 disposed below the heat exchanger 3;
Reference numeral 8 denotes an air filter provided behind the suction port 9.

During operation of the air conditioner, the fan 4 rotates,
Refrigerant from an outdoor unit (not shown) circulates through the heat exchanger 3. Then, as indicated by the solid arrow,
The air is sucked into the main body 1 through the suction port 9 and
After the dust contained therein is removed by flowing through the heat exchanger, the refrigerant is cooled or heated by exchanging heat with the refrigerant in the process of flowing through the heat exchanger 3. Next, it is urged by the once-through fan 4, and thereafter, the outlet
It is guided by the bag 6 and blown out into the room.

[0004]

In the above-mentioned conventional air conditioner, the flow velocity of the air flow sucked into the once-through fan 4 is large at the central portion and gradually decreases toward both ends due to the characteristics of the once-through fan 4. Therefore, the wind speed distribution flowing through the lower portion of the suction port 9 and the lower portion of the heat exchanger 3 becomes faster at the central portion than at other portions, and based on this, not only noise called a pure tone is generated but also the heat exchanger 3 Has an unbalanced heat exchange rate, and deteriorates the heat exchange performance.

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-mentioned problems, and the gist of the present invention is to provide a heat exchanger extending vertically inside a main body, and a downstream heat exchanger. And a front panel having a suction port on the upstream side of the heat exchanger, wherein the front panel has a front panel having a suction port upstream of the heat exchanger. An air conditioner characterized by forming a protruding wind shield wall that extends.

[0006]

According to the present invention, since the above structure is provided, the airflow passing through the center of the airflow sucked into the main body from the lower portion of the suction port is suppressed by the wind shield wall.
The bias of the wind speed distribution at the lower part of the suction port is reduced.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG. 1, and FIG. 1 is a front view of an air conditioner viewed from the front. The front panel 2 is formed with a convex wind shield wall 11 extending smoothly upward toward the center of the lower portion of the suction port 9. FIG. 2 shows another configuration.
And the corresponding members are denoted by the same reference numerals.

During operation of the air conditioner,
The airflow passing through the center of the airflow sucked into the main body 1 from the lower portion of the air inlet 1 is suppressed by the wind shield wall 11, so that the deviation of the wind speed distribution along the horizontal direction below the inlet 9 is reduced.

[0009]

[Effect of the Invention] In the present invention, the front panel is formed with a convex wind-shield wall extending smoothly upward toward the center of the lower portion of the suction port. Since the airflow passing through the center is suppressed by the wind shield wall, the bias of the wind speed distribution at the lower portion of the suction port is reduced. As a result, generation of noise called pure tone can be prevented, and the imbalance in the heat exchange rate at the lower part of the heat exchanger is reduced, so that the performance of the heat exchanger is improved.
