Description

An air conditioning system with duct apparatus

The present invention relates to an integrated air conditioner, and more particularly, to an air conditioner having a discharge duct for guiding cooling air blown by a fan to a discharge port side.

In general, an air conditioner is divided into an integrated unit in which an evaporator and a condenser forming a refrigeration cycle are installed in one cabinet, and a separate type in which they are separately installed in each cabinet. In the integrated air conditioner, a part of the cabinet in which the evaporator is disposed is located at the indoor side, and the other part of the cabinet in which the condenser is disposed is located at the outdoor side.

As shown in FIG. 1, such a conventional integrated air conditioner includes a blower 3, a propeller 4, and a blower 3 disposed in the cabinet 1 forming an exterior to simultaneously rotate through a single motor 2. ) An evaporator 5 provided on the front side and a condenser 6 provided on the back side of the propeller 4.

In addition, the front cover 7 is provided on the front side of the cabinet 1 in which an intake port 7a for sucking indoor air and a discharge hole 7b for discharging the heat-exchanged air back into the room are provided.

In the middle of the cabinet 1, a blower 3 is accommodated, a motor 2 is fixedly installed, and a frame 10 having a discharge duct 13 for guiding air discharge is disposed.

The frame 10 has a lower portion of the blower 3 and the lower frame 11 to which the motor 2 is seated, and an upper portion of the blower 3 and the lower portion of the blower 3. It is provided with an upper frame 12 is provided. The discharge duct 13 extends from the upper end of the upper frame 12 toward the discharge port 7b. The discharge duct 13 is provided in a rectangular tube type in which a front corresponding to the discharge port 7b is opened in order to secure a proper air volume.

The frame 10 is a plastic injection molding, and the lower frame 11 is fixed to the base plate of the cabinet 1, and the upper frame 12 having the discharge duct 13 is mounted on the lower frame 11 and air. It guides the discharge and at the same time supports the exterior of the cabinet 1.

When the compressor (not shown) and the motor 2 are driven in the conventional integrated air conditioner configured as described above, the outside air is sucked into the cabinet 1 by the suction blowing force of the propeller 4 and the condenser 6 is condensed. . At the same time, the indoor air is sucked to the evaporator 5 side through the suction port 7a and cooled by the suction blowing force of the blower 3. Subsequently, the cooling air is forcedly blown to the discharge port 7b side through the discharge duct 13 provided in the frame 10 and discharged again to the room, thereby harmonizing the indoor air.

However, in the conventional integrated air conditioner, there is a disadvantage in that the upper surface 13a of the discharge duct 13 of the upper frame 12 composed of the injection molding is deformed by its own weight. That is, the discharge duct 13 is a rectangular tube type extending in the horizontal direction, and the injection molding of the plastic material, the center portion of the upper surface 13a of the discharge duct 13 is struck in the downward direction (arrow G direction) by its own weight. Flexural deformation occurs. Due to the deformation of the discharge duct 13, there is a problem that the cold air flow path cannot be sufficiently secured, and product reliability is lowered.

In order to solve this problem, conventionally, a separate support device was installed inside the discharge duct 13 to prevent bending deformation of the upper surface 13a of the discharge duct 13 after the injection of the upper frame 12. In this case, the warpage deviation of the discharge duct 13 was more severely generated depending on the injection conditions.

SUMMARY OF THE INVENTION The present invention has been made to solve this problem, and an object of the present invention is to improve the upper surface of the discharge duct of the square tube type for guiding the heat exchanged air through the evaporator to the discharge port side, to prevent its bending deformation and at the same time to provide a sufficient cold air flow path. It is to provide an air conditioner with a discharge duct that can be secured.
