ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a room air conditioner having a plurality of air blow openings and vanes disposed in each air blow opening as air direction control means.
2. Prior Art
FIG. 5
is a sectional view showing an air blow opening of a room air conditioner being a conventional ceiling-embedded air condition. In the drawing, reference numeral
1
denotes a decorative panel fixed to a room air conditioner main body; reference numeral

a
denotes an air blow opening for blowing out an air conditioned by a heat exchanger of a freezing cycle (not shown) inside of the main body; reference numeral

b
denotes an internal air passage in the decorative panel

; reference numeral
2
denotes a respective one of vanes arranged at each air blow opening

which controls an air blow direction; reference numeral

which is not used.
In the air blow opening
1
a
to which an air blow shutdown member

is mounted, an air is not blown out from the air blow opening

, but the unused air blow opening is the same as a used air blow opening

a
not having an air blow shutdown member in other respects. The air blow shutdown member

is hardly seen from a user because the member is positioned at the depth of an internal air passage

b.
A room air conditioner which is a conventional ceiling-embedded air conditioner is configured as described above. With such configuration, in the case where any of plural air blow openings
1
a
is not used, the air is merely shut down by an air blow shutdown member
3
provided at the depth of the internal air blow passage
1
b
. Except that, an unused air blow opening is not different from a used air blow opening. Therefore, there has been a problem that it is difficult for a user to discriminate whether or not the air blow opening is used.
SUMMARY OF THE INVENTION
The present invention has been made in order to solve such problem. It is an object of the present invention to provide a ceiling-embedded air conditioner capable of easily discriminating whether or not the air blow opening is used from the appearance of a decorative panel.
It is another object of the present invention to provide a ceiling-embedded air conditioner capable of easily discriminating whether or not the air blow opening is used, adjusting an air direction every air blow opening, and improving amenity from the viewpoints of human and material engineering.
A ceiling-embedded air conditioner of the present invention includes a decorative panel having: a plurality of air blow openings, an air blow shutdown member for shutting down an internal air passage of unused air blow opening(s) of the air blow openings, and vanes provided in the internal air passage of the air blow openings for changing an air direction, wherein a mount position of the vanes is in the vicinity of a surface of the decorative panel in the internal air passage, and unused air blow opening(s) of the air blow openings can be fully closed by the vane(s). Thus, it can be easily discriminated whether or not the air blow opening is used from the appearance.
Furthermore, all of the air blow openings are fully closed by the vanes when the air conditioner stops. Therefore, it is possible to easily discriminate operation of the air conditioner from the appearance.
Furthermore, a vane driving motor for driving a respective one of the vanes is provided in the decorative panel, whereby the air direction can be adjusted every air blow opening, and amenity is improved from the viewpoints of human and material engineering.
Furthermore, a resisting member for fixing the vane at an arbitrary position in its movable region is disposed between a vane bearing and a vane rotary shaft pivoted by the vane bearing provided at the decorative panel. For this configuration, an air direction can be adjusted every air blow opening, and amenity is improved from the viewpoints of human and material engineering.
