Abstract
A blower cover and an air conditioner using such blower. A rollable sheet is locked between two side plates by rollable connectors. A belt plate is secured between the side plates to lock the rollable sheet between the side plates. The belt plate also directs air from the blower. The blower cover can easily be assembled at a work site without welding or expert metal working. The blower cover is used in an air conditioner in which air is forced upwards from the blower and the air is directed into a heat exchange unit by one or more air deflectors. Another air deflector directs air coming out of the heat exchanger in an upwardly direction out of the air conditioner and this air deflector also directs any condensate downwards toward a drain system generally located below the heat air conditioner.
Claims20
A cover for a blower, the cover comprising:
- at least two side plates positioned substantially perpendicular to an imaginary common longitudinal line, each of the plates having an edge portion extending substantially parallel to the imaginary longitudinal line and towards the other plate;
- a rollable sheet comprised of a flexible material, the rollable sheet positioned between the two side plates, the sheet comprising left and right side edges;
- at least two rollable connectors, one for each of the side plates, each of the connectors comprising upper and lower walls that are parallel and a rib that connects to and spaces apart the walls so that each of the connectors defines a substantially H-shaped cross-section, the upper wall comprising upper left and right legs, the lower wall comprising lower right and left legs, with the legs on either side of the rib, said upper right leg being longer than the lower right leg;
- the upper right leg comprising a lip extension that extends from an open end of the upper right leg perpendicularly toward the lower right leg to form a substantially L-shaped cavity between the upper and lower right legs;
- a left cavity formed by the rib and the upper and lower left legs;
- and
- the edge portions of each of the side plates is secured in and along the L-shaped cavity of a respective one of the rollable connectors, and the side edges of the rollable sheet are each secured in the respective one of the left cavities of the rollable connectors.

A method of assembling a cover for a blower comprising:
- providing a blower having a central axis;
- positioning at least two side plates substantially perpendicular to an imaginary longitudinal line that extends through the blower axis, wherein each of the plates having an edge portion extending substantially parallel to the imaginary longitudinal line and towards the other plate;
- providing a rollable sheet comprised of a flexible material, the rollable sheet positioned between the two side plates and covering a longitudinal side of the blower, wherein the sheet comprises left and right side edges;
- providing at least two rollable connectors, one for each of the side plates, each of the connectors comprising upper and lower walls that are parallel and a rib that connects to and spaces apart the walls so that each of the connectors defines a substantially H-shaped cross-section, the upper wall comprising upper left and right legs, with the lower wall comprising lower right and left legs, with the legs on either side of the rib, said upper right leg being longer than the lower right leg, with the upper right leg comprising a lip extension that extends from an open end of the upper right leg perpendicularly toward the lower right leg to form a substantially L-shaped cavity between the upper and lower right legs, a left cavity formed by the rib and the upper and lower left legs;
- securing the edge portions of each of the side plates in and along the L-shaped cavity of a respective one of the rollable connectors;
- securing the side edges of the rollable sheet in the respective one of the left cavities of the rollable connectors;
- and
- providing a belt plate that extends the length between the two side plates and securing the belt plate to the side plates.

An air conditioner and blower comprising:
- a blower that forces air upward;
- a heat exchanger comprising substantially vertical air entering and air exiting faces, the heat exchanger having air passages between the air entering and the air exiting faces through which air from the blower passes therethrough and is cooled, the air entering and air exiting faces having upper and lower portions;
- an upper air deflector attached to the upper portion of the air entering face of the heat exchanger, the upper air deflector guides air from the blower into the air entering face;
- a lower air deflector positioned near the lower portion of the air exiting face of the heat exchanger, the lower air deflector guides air exiting out from the air exiting face of the heat exchanger towards an outlet, the lower air deflector comprises an upper surface on which condensed water may accumulate, the lower air deflector arranged so as to guide the condensed water downwards, assisted by gravity;
- and
- a water drain system which receives and expels the condensed water that is directed by the lower air deflector.
