Abstract

A locking claw on an outer face of a container portion made of resin is engaged with a locking hole in an outer periphery of a case made of sheet metal, the container portion being covered by the case, a locking claw on an outer face of a cover is engaged with a locking hole in an outer periphery of a lid body, the cover being covered by the lid body, they are assembled so that a part of an opening edge of an opening portion of the case is covered by an opening edge of an opening portion of the cover, the container portion and the case as well as the cover and the lid body are fixed to form an electric equipment box and a flame spread inhibiting path is formed between the lid body and the case.

First claim

What is claimed is:

1. An air conditioner that is a wall-hung air conditioner comprising:
a heat exchanger;
a fan; and
an electric equipment box in a main body of an indoor unit,
wherein said electric equipment box includes:
a container portion made of resin containing a control board, a terminal block and having an opening portion with a locking claw on an outer peripheral face;
a case made of sheet metal having an opening portion with a locking hole engaged with the locking claw of said container portion on an outer periphery thereof;
a cover made of resin having an opening portion with a locking claw on an outer peripheral face thereof; and
a lid body made of sheet metal having an opening portion with a locking hole engaged with the locking claw of said cover on an outer periphery thereof,
wherein the locking claw of said container portion is engaged with the locking hole of said case so that said case covers the outer peripheral face of the container portion, the locking claw of said cover is engaged with the locking hole of said lid body so that said lid body covers the outer peripheral face of said cover, an engaged portion of the locking claw of said container portion and the locking hole of said case is configured to be covered by said lid body by assembling an opening edge of the opening portion of said case covering said container portion to be covered by an opening edge of the opening portion of said cover covered by said lid body, and said cover and said lid body are fixed to said container portion and said case; and
between an opening end of said lid body and an opening end of said case, a flame spread inhibiting path of a predetermined length is formed in which the opening edge of said lid body and the opening edge of said case overlap.

2. The air conditioner of claim 1 , wherein positions of the locking hole of said case and the locking hole of said lid body are displaced from each other so as not to overlap.

3. The air conditioner of claim 1 , wherein said lid body is formed by sheet-metal drawing work.

4. The air conditioner of claim 2 , wherein said lid body is formed by sheet-metal drawing work.

5. The air conditioner of claim 1 , wherein a flange portion with the same height dimension as the plate thickness of said case is disposed in parallel with the opening end on the opening side of the locking claw of said container portion.

6. The air conditioner of claim 2 , wherein a flange portion with a same height dimension as a plate thickness of said case is disposed in parallel with an opening end on the opening side of the locking claw of said container portion.

7. The air conditioner of claim 3 , wherein a flange portion with a same height dimension as a plate thickness of said case is disposed in parallel with an opening end on the opening side of the locking claw of said container portion.

8. The air conditioner of claim 4 , wherein a flange portion with a same height dimension as a plate thickness of said case is disposed in parallel with an opening end on the opening side of the locking claw of said container portion.
