Abstract

An outdoor unit for an air-conditioning apparatus includes a machine chamber in which a compressor serving as a vibration source and at least two refrigerant-circuit components and are provided. One of the refrigerant-circuit components and is provided with an elastic tab while an other refrigerant-circuit component or is provided with a catching portion that is engageable with the elastic tab. The refrigerant-circuit components and are brought into close contact with each other by the elastic tab and the catching portion.

First claim

1 . An outdoor unit for an air-conditioning apparatus, the outdoor unit comprising:
a machine chamber in which a compressor serving as a vibration source and at least two refrigerant-circuit components are provided, wherein one of the refrigerant-circuit components is provided with an elastic tab while an other refrigerant-circuit component is provided with a catching portion that is engageable with the elastic tab, and wherein the refrigerant-circuit components are in close contact with each other by the elastic tab and the catching portion.

2 . The outdoor unit for an air-conditioning apparatus of claim 1 ,
wherein the elastic tab includes
a base portion extending outward;
a lock portion extending downward from a tip of the base portion; and
a guide portion extending outward from a lower end of the lock portion while sloping downward, and
wherein the guide portion is configured to, when the elastic tab is fit in the catching portion, be in contact with and slide along an edge of the catching portion, to cause the lock portion to elastically deform and store a restoring force urging the refrigerant-circuit components toward each other and bring the refrigerant-circuit components into close contact with each other.

3 . The outdoor unit for an air-conditioning apparatus of claim 1 , wherein a surface of the catching portion with which the elastic tab is configured to be in contact is provided with a rubber component.

4 . The outdoor unit for an air-conditioning apparatus of claim 1 , wherein the refrigerant-circuit components are temporarily fixable to each other by the elastic tab and the catching portion before finally being fastened to a bottom plate of the machine chamber with a screw.

5 . The outdoor unit for an air-conditioning apparatus of claim 1 , wherein the refrigerant-circuit components are an accumulator and a component connecting pipes between the outdoor unit and an indoor unit.
