Abstract

An outdoor unit for an air conditioning device includes an outdoor unit main body, a heat exchanger, a fan provided in an upper part of the outdoor unit main body, the fan blowing out the air taken in from a side surface of the outdoor unit main body upward, a ventilating member surrounding an outer circumference of the fan and forming a blow-out port, and an electric component unit accommodated in the outdoor unit main body and arranged in an opening portion between one side end portion and the other side end portion of the heat exchanger, wherein the electric component unit is provided so as to cross over a lower end of the ventilating member in the up and down direction, and on the upper side than the lower end of the ventilating member, the electric component unit is arranged on the horizontally outer side than the ventilating member.

First claim

The invention claimed is:

1. An outdoor unit for an air conditioning device, comprising:
an outdoor unit main body;
a heat exchanger accommodated in the outdoor unit main body, the heat exchanger having a first horizontal end portion and a second horizontal end portion separated by an open space;
a fan provided in an upper part of the outdoor unit main body, the fan blowing out air taken in from side surfaces of the outdoor unit main body;
a ventilating member, having an upper end and a lower end, surrounding an outer circumference of the fan and forming a blow-out port of the air at a top of the upper part of the outdoor unit main body; and
an electric component unit accommodated in the outdoor unit main body and arranged in the open space between the first horizontal end portion and the second horizontal end portion of the heat exchanger, wherein
the electric component unit extends vertically across the lower end of the ventilating member,
a part of the electric component unit is arranged vertically higher than the lower end of the ventilating member and is arranged horizontally outside of an outer edge of the ventilating member,
the electric component unit includes an electric component box for accommodating an electric component, and
the electric component box includes a first intake port for taking the air into the electric component box formed vertically higher than the lower end of the ventilating member, and a discharge port for discharging the air in the electric component box formed vertically lower than the lower end of the ventilating member.

2. The outdoor unit for the air conditioning device according to claim 1 , wherein the electric component box further includes
a second intake port for taking the air into the electric component box formed vertically lower than the discharge port in a lower portion of the electric component box.

3. The outdoor unit for the air conditioning device according to claim 2 , wherein
a high heat generating part is arranged in the lower portion of the electric component box.

4. The outdoor unit for the air conditioning device according to claim 3 , wherein the electric component box further includes
an arrangement recess portion for arranging a cooling refrigerant pipe for cooling down the high heat generating part in the planar range of the electric component box formed in the lower portion of the electric component box.

5. The outdoor unit for the air conditioning device according to claim 4 , wherein the arrangement recess portion is formed by recessing a part of a bottom wall of the electric component box upward, and an electric wire in the electric component box is pulled out to an exterior from a bottom wall in the arrangement recess portion.

6. The outdoor unit for the air conditioning device according to claim 2 , wherein
the second intake port is formed on a bottom vertical face of the electric component box.
