Abstract

A fan mechanism includes fan units having fan panels, motors mounted inwardly of said fan panels, fans positioned inwardly of the fan panels and driven by the motors, where a pair of vertical rails is mounted on both sides of each of discharge openings inwardly of the front plate so that the inner portions thereof face each other, panel retainers are attached inwardly to the lower portions of the discharge openings, press portions are formed at upper portions of both sides of the fan panels, both sides of each fan panel are pushed down into the vertical rails downward from above while being guided by the pair of vertical rails, the lower edge of the fan panel rides on the panel retainer, and the press portions are pushed down into the vertical rails, so that the fan panel is pressed against the inside of the front plate.

First claim

What is claimed is:

1. A duct type air conditioner comprising at least: a casing having discharge openings and a suction opening therein; said casing being composed of a front plate formed with a discharge duct mounting frame outwardly thereof so as to surround the discharge openings; a fan mechanism mounted inwardly of said front plate; said casing being further composed of a back plate formed with a suction duct mounting frame outwardly thereof so as to surround said suction opening; and a heat exchanger mounted inwardly of said back plate,
wherein
said fan mechanism includes a plurality of fan units each having a fan panel, a motor mounted on the fan panel, a pair of press portions integrally formed with the fan panel on top of the fan panel with bent top two corners of each fan panel orthogonally towards a side on which the motor is mounted, and a discharge port formed on the fan panel,
a pair of L-shaped vertical rails is mounted on the front plate on a side the fan mechanism is mounted and at both sides of each of the discharge openings,
two panel retainers are attached on the front plate and located on bottom of each of the discharge openings and in between the pair of L-shaped vertical rails,
said two panel retainers are separated from each other,
each of the panel retainers comprises: a surface portion inclined relative to the front plate to guide the fan panel; and a stopper portion integrally formed with the surface portion and forming a bottom of each panel retainer to fit the fan panel, and
each of the plurality of fan units is mounted on the front plate of the casing by inserting a pair of side edges of the fan panel into the pair of L-shaped vertical rails of the front plate respectively and by pressing the pair of press portions of the fan panel downwardly until the fan panel abuts the stopper portion of the panel retainers and until each press portion is completely pressed into a space surrounded by the L-shaped vertical rail and the front plate, so that the fan panel is pressed against the front plate and each discharge port faces each of the discharge openings.

2. The duct type air conditioner according to claim 1 ,
wherein each of the panel retainers comprises an inclined surface portion opening inwardly and a stopper portion having a shape of a frame to form a bottom for guiding and fitting a lower edge of the fan panel.

3. The duct type air conditioner according to claim 1 ,
wherein a handle portion, which is bent inwardly, is formed at an upper end of each of the fan panels.

4. The duct type air conditioner according to claim 1 ,
wherein the air flow is reversed through the air conditioner such that
the discharge openings serves as the suction opening,
the suction opening serves as the discharge openings,
the discharge duct mounting frame serves as the suction duct mounting frame, and
the suction duct mounting frame serves as the discharge duct mounting frame.

5. The duct type air conditioner according to claim 2 ,
wherein a handle portion, which is bent inwardly, is formed at an upper end of each of the fan panels.

6. The duct type air conditioner according to claim 2 ,
wherein the air flow is reversed through the air conditioner such that
the discharge openings serves as the suction opening,
the suction opening serves as the discharge openings,
the discharge duct mounting frame serves as the suction duct mounting frame, and
the suction duct mounting frame serves as the discharge duct mounting frame.

7. The duct type air conditioner according to claim 3 ,
wherein the air flow is reversed through the air conditioner such that
the discharge openings serves as the suction opening,
the suction opening serves as the discharge openings,
the discharge duct mounting frame serves as the suction duct mounting frame, and
the suction duct mounting frame serves as the discharge duct mounting frame.

8. The duct type air conditioner according to claim 5 ,
wherein the air flow is reversed through the air conditioner such that
the discharge openings serves as the suction opening,
the suction opening serves as the discharge openings,
the discharge duct mounting frame serves as the suction duct mounting frame, and
the suction duct mounting frame serves as the discharge duct mounting frame.

9. The duct type air conditioner according to claim 1 ,
wherein the fan units comprises: motor supports mounted inwardly of said fan panels; and spacers mounted to said motor supports.

10. The duct type air conditioner according to claim 1 ,
wherein the fan units comprises: reinforcing plates mounted inwardly of said fan panels; and motor supports mounted to said reinforcing plates.
