Abstract

PROBLEM TO BE SOLVED: To stabilize heat exchanging performance by enhancing draining efficiency of an outdoor unit of air conditioning equipment. SOLUTION: A plurality of louver-shaped upright rise tabs 10 are arranged at positions corresponding to an outdoor heat exchanger 6 of a bottom plate 2 where an outdoor heat exchanger 6, an outdoor blower, a compressor and the like are arranged. As a result, draining area can be expanded without reducing the strength of the bottom plate 2 so that defrosted water and rain water flowing down from the outdoor heat exchanger 6 can be discharged more quickly to eliminate freezing between the bottom plate 2 and the outdoor heat exchanger 6 thereby stabilizing heat exchangeability.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor unit for an air conditioner, and more particularly to a means for increasing the drainage efficiency inside the main body.

[0002]

2. Description of the Related Art An outdoor unit for an air conditioner has a structure as shown in FIG. 4 and a machine room 5. An L-shaped outdoor heat exchanger 6 and an outdoor blower 7 are arranged in the heat exchange room 4, and a compressor 8 in the machine room 5 and the compressor 8 and the like are controlled. The control device 9 and the like are arranged. Further, the bottom plate 2 is provided with drainage holes 11 as shown in FIG. 4 for discharging rainwater that has entered the main body 1 and defrosted water from the outdoor heat exchanger 6. In addition,
As shown in FIGS. 4 and 5, the peripheral portion of the drainage hole 11 is made one step lower than the surface on which the outdoor heat exchanger 6 is mounted to promote drainage.

[0003]

However, since the conventional bottom plate 2 having only one drain hole 11 has poor drainage efficiency, the water accumulated on the bottom plate 2 may freeze in winter.
When the drain hole 11 is blocked by the growth of ice, the drainage becomes impossible, the growth of ice becomes more and more active, the bottom of the outdoor heat exchanger 6 is covered with ice, and the predetermined heat exchange cannot be performed. The problem occurs. In order to prevent such a problem from occurring, it is effective to make the drain holes 11 large or increase the number of drain holes 11, but with such measures, the strength of the bottom plate 2 is lowered and the outdoor heat exchanger 6 is used. May adversely affect the ventilation of. Therefore, it is an object of the present invention to provide an outdoor unit for an air conditioner that improves drainage efficiency without lowering the heat exchange performance and the strength of the bottom plate.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and divides the inside of the main body into a heat exchange chamber and a machine chamber by partition plates that are erected between the front and rear of the bottom plate. In an outdoor unit of an air conditioner in which an outdoor heat exchanger and an outdoor blower are arranged in a heat exchange chamber and a compressor or the like is arranged in a machine room, a plurality of positions of the bottom plate corresponding to the outdoor heat exchanger are provided. I decided to make a louvered cut and raised piece.

[0005]

With the above-mentioned structure, the drainage efficiency can be improved and the louver-shaped cut-and-raised shape can be obtained by the presence of the plurality of holes formed by the cut-and-raised all over the lower part of the outdoor heat exchanger. As a result, the original strength of the bottom plate can be maintained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. Fig. 1 shows the schematic configuration of the outdoor unit.
Reference numeral 1 is a main body having an intake port for outside air on one rear side and one side, and an air outlet on one front side. The inside of the main body 1 is partitioned into a heat exchange chamber 4 and a machine room 5 by partition plates 3 provided upright in front of and behind the bottom plate (base) 2, and in the heat exchange chamber 4, an outdoor heat exchanger 6 and An outdoor blower 7 is arranged, and a compressor 8 and a control device 9 for controlling the compressor 8 and the outdoor blower 7 are arranged in the machine room 5. The outdoor heat exchanger 6 is L-shaped and is erected on the bottom plate 2.

The feature of this embodiment is that a plurality of cut-and-raised parts 10 are formed at positions corresponding to the bottom surface of the outdoor heat exchanger 6 of the bottom plate 2, as shown in FIG. Each of these cut-and-raised parts 10 has a louver shape as shown in FIG. 3, and the upper end portion thereof abuts the bottom surface side of the outdoor heat exchanger 6 to support the outdoor heat exchanger 6. . In the present embodiment, the cut and raised 10
The upper end of the heat exchanger is brought into contact with the bottom surface side of the outdoor heat exchanger 6, but the invention is not necessarily limited to such a form, and a slight gap may be formed between the cut-and-raised part 10 and the outdoor heat exchanger 6. Even if there is, there is no particular problem.

[0008]

As described above, in the case of the outdoor unit having the bottom plate as described above, the defrosting water and the rainwater flowing down from the outdoor heat exchanger are quickly drained, so that the ice grows on the bottom plate. Without this, the heat exchange performance is stable, and since the cut-and-raised parts formed on the bottom plate are louver-shaped, the outdoor unit is also stable in strength.
