Abstract

A power supply panel includes an engagement portion. An electrical component box includes a hook portion that engages with the engagement portion. A temporarily fixed state in which the power supply panel is attached to the electrical component box is set when the engagement portion engages with the hook portion.
A securely fixed state in which the power supply panel is positioned inside the outer periphery of a housing, as the housing is seen in a plan view, and the power supply panel is positioned below the electrical component box is set when the electrical component box is placed in a machine chamber and the power supply panel is attached to the housing.

First claim

The invention claimed is:

1. An outdoor unit of an air-conditioning apparatus, the outdoor unit comprising:
a housing in which a machine chamber is formed, the machine chamber is adapted to have disposed therein a compressor of the air-conditioning apparatus and a refrigerant pipe of the air-conditioning apparatus;
an electrical component box disposed in the machine chamber; and
a power supply panel including a terminal block to which a connection wire is attached, the connection wire being connected to an electrical component held in the electrical component box and adapted for connection to an indoor unit of the air-conditioning apparatus,
the power supply panel including a first power-supply-panel-side engagement member, and
the electrical component box including an electrical-component-box-side engagement member that engages with the first power-supply-panel-side engagement member,
wherein a first state in which the power supply panel is attached to the electrical component box is set when the first power-supply-panel-side engagement member and the electrical-component-box-side engagement member engage with each other, and
wherein a second state in which the power supply panel is positioned inside an outer periphery of the housing, as the housing is seen in a plan view, and the power supply panel is positioned below the electrical component box is set when the electrical component box is placed in the machine chamber and the power supply panel is attached to the housing from a state in which the first state is released and the power supply panel is removed from the electrical component box.

2. The outdoor unit of an air-conditioning apparatus of claim 1 ,
wherein the first power-supply-panel-side engagement member is an engagement portion formed in the power supply panel,
wherein the electrical-component-box-side engagement member is a hook portion that engages with the engagement portion, and
wherein the first state is set when the engagement portion and the hook portion engage with each other.

3. The outdoor unit of an air-conditioning apparatus of claim 1 , further comprising:
a side panel configured to cover the machine chamber,
wherein the power supply panel includes a second power-supply-panel-side engagement member,
wherein the side panel includes a side-panel-side engagement portion that engages with the second power-supply-panel-side engagement member, and
wherein the second state is set when the electrical component box is placed in the machine chamber, the second power-supply-panel-side engagement member engages with the side-panel-side engagement portion, and the power supply panel is attached to the housing.

4. The outdoor unit of an air-conditioning apparatus of claim 1 ,
wherein a space is formed inside an outer periphery of the housing, as the housing is seen in a plan view, and
below the electrical component box, and wherein the second state includes a second state in which the power supply panel is positioned in the space and which is set when the electrical component box is placed in the machine chamber and the power supply panel is attached to the housing.

5. An outdoor unit of an air-conditioning apparatus, the odoor unit comprising:
a housing in which a machine chamber is formed;
an electrical component box disposed in the nmachine chamber; and
a power supply panel including a terminal block to which a connection wire is attached, the connection wire being connected to an electrical component held in the electrical component box,
the power supply panel including a first power-supply-panel-side engagement member, and
the electrical component box including an electrical-component-box-side engagement member that engages with the first power-supply-panel-side engagement member,
wherein a first state in which the power supply panel is attached to the electrical component box is set when the first power-supply-panel-side engagement member and the electrical-component-box-side engagement member engage with each other, and
wherein a second state in which the power supply panel is positioned inside an outer periphery of the housing as the housing is seen in a plan view, and the power supply panel is position below the electrical component box is set when the electrical component box is placed in the machine chamber and the power supply panel is attached to the housing,
wherein the power supply panel includes a rib,
wherein the electrical component box includes an electrical-component-box-side slide surface, a first stopper, a second stopper, and a fixing piece,
wherein the second stopper is positioned more to a side defined by a first direction than the first stopper,
wherein the electrical-component-box-side slide surface is positioned more to a side defined by a second direction than the fixing piece,
wherein the first state is set when, in a state in which the first power-supply-panel-side engagement member and the electrical-component-box-side engagement member are engaged with each other, the power supply panel slides over the electrical-component-box-side slide surface by a reference distance in the first direction and the rib passes over the first stopper, and
wherein, in the first state,
movement of the power supply panel in a direction opposite to the first direction is restrained by the first stopper,
movement of the power supply panel in the first direction is restrained by the second stopper,
movement of the power supply panel in a direction opposite to the second direction is restrained by the fixing piece, and
movement of the power supply panel in the second direction is restrained by the electrical-component-box-side engagement member.

6. The outdoor unit of an air-conditioning apparatus of claim 5 ,
wherein the first power-supply-panel-side engagement member is an engagement portion formed in the power supply panel,
wherein the electrical-component-box-side engagement member is a hook portion that engages with the engagement portion, and
wherein the first state is set when the engagement portion and the hook portion engage with each other.

7. The outdoor unit of an air-conditioning apparatus of claim 5 , further comprising:
a side panel configured to cover the machine chamber,
wherein the power supply panel includes a second power-supply-panel-side engagement member,
wherein the side panel includes a side-panel-side engagement portion that engages with the second power-supply-panel-side engagement member, and
wherein the second state is set when the electrical component box is placed in the machine chamber, the second power-supply-panel-side engagement member engages with the side-panel-side engagement portion, and the power supply panel is attached to the housing.

8. The outdoor unit of an air-conditioning apparatus of claim 5 ,
wherein a space is formed inside an outer periphery of the housing, as the housing is seen in a plan view, and
below the electrical component box, and wherein the second state includes a second state in which the power supply panel is positioned in the space and which is set when the electrical component box is placed in the machine chamber and the power supply panel is attached to the housing.

9. An outdoor unit of an air-conditioning apparatus, the outdoor unit comprising:
a housing in which a machine chamber that holds a compressor and a refrigerant pipe of the air-conditioning apparatus is formed;
an electrical component box disposed in an upper part of the machine chamber and holds an electrical component; and
