Abstract

A ceiling-embedded air conditioner includes: a pipe draw portion that is provided at one corner portion of a casing main body to draw refrigerant pipes together with an electric wire; a pipe cover that fixes the peripheries of the refrigerant pipes and has a draw hole for the electric wire; a wire cover that is provided on the bottom surface of the casing main body and cover a wire guide groove for the electric wire; a cover plate that is included in the wire cover, covers the wire guide groove, and is screwed to a predetermined place on the casing main body side; and a hold plate that is included in the wire cover and is folded at a right angle from one end of the cover plate to engage with a pipe cover end portion of the pipe cover on the bottom surface side of the casing main body.

First claim

What is claimed is:

1. A ceiling-embedded air conditioner comprising:
a ceiling-embedded casing main body that includes a heat exchanger, a turbo fan, and an electric equipment box inside, and has an air blowoff opening and an air suction opening in a bottom surface;
a pipe draw portion that is provided at one corner portion of the casing main body and is formed by cutting out part of the casing main body to draw refrigerant pipes of the heat exchanger together with an electric wire of the electric equipment box;
a pipe cover that is included in the pipe draw portion, fixes peripheries of the refrigerant pipes, and has a draw hole for the electric wire; and
a wire cover that is provided on the bottom surface of the casing main body and covers a wire guide groove for the electric wire, the wire guide groove being formed from the electric equipment box to the pipe draw portion;
wherein the wire cover includes a cover plate that covers the wire guide groove, and is screwed to a predetermined place on the casing main body bottom surface; and
a bent plate that is folded at a right angle from one end of the cover plate to engage with a pipe cover end portion of the pipe cover on a side of the bottom surface of the casing main body.

2. The ceiling-embedded air conditioner according to claim 1 , wherein
the cover plate has L-shaped guide grooves at two places,
the L-shaped guide grooves have:
first guide paths that extend in a first direction orthogonal to one side of the cover plate, the one side of the cover plate including the bent plate; and
second guide paths that extend in a second direction orthogonal to the first direction from ends of the first guide paths, the second guide paths are situated between the ends of the first guide paths and the bent plate on the bent plate side,
the casing main body has a male screw and an engagement convex portion in predetermined positions,
the male screw is configured to support movement of the cover plate along one of the L-shaped guide grooves and fix the cover plate in a predetermined position, and
the engagement convex portion supports movement of the cover plate along another of the L-shaped guide grooves.

3. The ceiling-embedded air conditioner according to claim 1 , wherein
a foamed resin heat insulator is disposed on an inner peripheral surface of the casing main body,
at a predetermined place of the heat insulator, a seal portion in abutment with an end plate of a side end portion of the heat exchanger extends in a direction parallel to an engagement surface between the bent plate and the pipe cover end portion, and
when the wire cover engages with the pipe cover end portion, the seal portion is pressed against the end plate of the side end portion of the heat exchanger.

4. The ceiling-embedded air conditioner according to claim 2 , wherein
a foamed resin heat insulator is disposed on an inner peripheral surface of the casing main body, and
at a predetermined place of the heat insulator, a seal portion in abutment with an end plate of a side end portion of the heat exchanger extends in a direction parallel to an engagement surface between the bent plate and the pipe cover end portion, and when the wire cover engages with the pipe cover end portion, the seal portion is pressed against the end plate of the side end portion of the heat exchanger.
