Description

[Detailed Description of the Invention] The present invention relates to an outdoor unit of an air conditioner with an improved drainage structure for drain water.

This type of outdoor unit has an outdoor heat exchanger in its main body and a drain outlet on the bottom plate, and the drain water flowing down from the heat exchanger when defrosting the outdoor heat exchanger is used as described above. The drain is drained to the outside through the drain outlet.

However, in conventional systems, the outdoor heat exchanger was installed close to the drain outlet, so as the outside temperature drops, the drain outlet is more likely to freeze, and if the operation continues for a long time, the bottom plate metal body will freeze. At the same time, the lower part of the outdoor heat exchanger freezes, reducing heating capacity and causing deformation and damage to the outdoor heat exchanger.

The present invention was developed in view of the above circumstances, and its purpose is to form an opening by forming a cut and raised piece on the bottom plate of the outdoor unit body, and to use the opening as a drain outlet. The present invention aims to provide an outdoor unit of an air conditioner in which the outdoor heat exchanger and the drain outlet are separated from each other by using a cut and raised piece as a mounting part for the outdoor heat exchanger.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes the main body of the outdoor unit, and a U-shaped outdoor heat exchanger 2 is installed upright on one side of the bottom plate 1a, and a compressor 3 is installed on the other side.

Further, a blower 4 is provided on the bottom plate 1a so as to be surrounded by the outdoor heat exchanger 2.

5 is a partition plate.

On the other hand, the bottom plate 1 facing the lower end surface of the outdoor heat exchanger 2 has a plurality of cut and raised pieces 6 as shown in FIG.
. . . are formed, and the formation path of these cut and raised pieces 6 . . . becomes a drain drainage lower . . . as shown in FIG.

The outdoor heat exchanger 2 has these cut and raised pieces 6...
It is placed on the top of the .

Further, an indoor heat exchanger (not shown) of an indoor unit is communicated with the outdoor heat exchanger 2 via a refrigerant pipe to constitute a refrigeration cycle.

Then, the refrigeration cycle is activated and the blower 4 is activated.
When activated, outdoor air is sent to the outdoor heat exchanger 2, and the refrigerant evaporates within the outdoor heat exchanger 2 during heating operation.

During this heating operation, drain water is generated on the surface of the outdoor heat exchanger 2 and eventually forms frost, but this frost is defrosted by the defrosting mechanism and flows down as drain water.

This drain water that has fallen onto the bottom plate 1a of the main body 1 into the unit 1 is also discharged to the outside through the drain drain lower as shown by the arrow in FIG.

As mentioned above, the outdoor heat exchanger 2 is cut and raised to form pieces 6...
Because it is placed on the upper surface, the outdoor heat exchanger 2 and the drain drain lower... are separated by a large distance, and the rotation of the blower 4 causes the drain drain lower...... to pass through. The amount of air flow increases, making it difficult to connect the drain lower.

Therefore, the bottom plate 1a of the unit body 1 and the 2,000 parts of the outdoor heat exchanger are prevented from freezing.

Further, since the outdoor heat exchanger 2 is placed on the cut and raised pieces 6, a separate support member for the heat exchanger 2 is not required, and the installation work is facilitated.

As explained above, the present invention forms an opening by forming a cut and raised piece on the bottom plate of the outdoor unit main body, and uses the opening as a drain outlet, and also uses the cut and raised piece for outdoor heat exchange. Since the outdoor heat exchanger and the drain outlet are separated from each other, the amount of air passing through the drain outlet increases, and the drain outlet becomes difficult to freeze.

Therefore, the bottom plate of the unit main body and the outdoor heat exchanger are prevented from freezing, the heating capacity is maintained well, and the outdoor heat exchanger is prevented from being deformed or damaged.

In addition, since the outdoor heat exchanger is mounted on a cut-and-raised piece, there is no need for a separate support member for the heat exchanger, making it economical and providing excellent installation stability. be.
