Abstract

An outdoor unit for an air-conditioning apparatus according to the present disclosure includes a heat exchanger comprised of an upper heat exchanger and a lower heat exchanger that are arranged in an up-down direction, an accumulator configured to store refrigerant, a casing, an inside of which is partitioned by a partition plate into an air-sending chamber accommodating the heat exchanger and a machine chamber accommodating the accumulator, and a fixing component configured to be fixed to the heat exchanger and the accumulator so that the accumulator is fixed to the heat exchanger, wherein the fixing component is fixed to both of the upper heat exchanger and the lower heat exchanger.

First claim

The invention claimed is:

1. An outdoor unit for an air-conditioning apparatus, comprising:
a heat exchanger comprised of an upper heat exchanger and a lower heat exchanger that are arranged in an up-down direction;
an accumulator configured to store refrigerant;
a casing, an inside of which is partitioned by a partition plate into an air-sending chamber accommodating the heat exchanger and a machine chamber accommodating the accumulator; and
one fixing component configured to be fixed to the heat exchanger and the accumulator so that the accumulator is fixed to the heat exchanger, wherein
the one fixing component is fixed to both of the upper heat exchanger and the lower heat exchanger,
the one fixing component includes a first fixing component fixed to the accumulator and a second fixing component fixed to the first fixing component and the heat exchanger,
an opening is formed in one of the first fixing component and the second fixing component, and
a claw portion configured to engage with the opening is formed in another of the first fixing component and the second fixing component.

2. The outdoor unit for an air-conditioning apparatus of claim 1 , wherein
the upper heat exchanger includes a first end plate provided in an end portion on a closer side to the machine chamber,
the lower heat exchanger includes a second end plate provided in an end portion on a closer side to the machine chamber, and
the one fixing component is fixedly screwed to the first end plate and is fixedly screwed to the second plate.

3. The outdoor unit for an air-conditioning apparatus of claim 1 , further comprising:
a support component configured to be fixed to a lower surface portion of the casing and a lower surface portion of the accumulator to support the accumulator from below.
