Abstract: A grille for ventilation apparatus arranged downstream of insufflation elements of a ventilation apparatus, the grille including a grid portion arranged upstream of a stator portion. The insufflation elements may include a fan. The grid portion may include fins which form concentric rings.

Abstract: A vertical discharge condenser includes a generally cylindrical heat exchanger having a vertical interruption between a first and a second end of the heat exchanger, a panel enclosing the vertical interruption in the heat exchanger to form an uninterrupted generally cylindrical enclosure, a generally circular fan grille enclosing a top of the cylindrical enclosure, and a generally circular base pan enclosing a bottom of the cylindrical enclosure.

Abstract: An orifice member for the condenser fan of an air conditioning unit which has a basepan and partition dividing the unit into an indoor section forward or the partition and an outdoor section behind the portion. The wall section has at least one through opening therein laterally spaced from the centerline of the orifice and in close proximity to the basepan. The opening communicates the region of the basepan on the high pressure side of the wall section with the low pressure side region of the basepan, which contains the sub-cooling coil. The opening is located and configured such that when the air conditioner is operating and condensate has collected in the basepan, condensate will be pumped through the opening from the high pressure side to the low pressure side and thereby cause turbulence in the condensate in the region of the basepan which contains the sub-cooling coil.

Abstract: A room air conditioner unit of the type having a basepan, which is divided into indoor and outdoor sections by a partition. The indoor section includes an evaporator coil, an evaporator fan and a scroll for directing indoor air flow. The outdoor section includes a compressor, a condenser coil, a condenser fan, a condenser fan shroud and an electric motor. The motor is configured to drive both the evaporator and condenser fans. A first partition wall section is attached to the basepan and has a height less than the overall height of the partition. A first condenser fan shroud section is also attached to the basepan and has a height less than the overall height of the condenser fan shroud. A molded component having a top wall is configured to overlie at least a portion of both the indoor section and the outdoor section. The top wall has, integrally formed therewith, a downwardly extending partition wall section.

Abstract: Apparatus for alternatively mounting either a large cylindrical capacitor having a given length and a given diameter or a small cylindrical capacitor having a given length and a given diameter. The apparatus includes a substantially planar support wall having two or more substantially U-shaped support walls extending substantially perpendicularly therefrom. The U-shaped support walls are parallel to one another and are spaced from one another by a distance such that at least two of the U-shaped walls will span the given length of either of the capacitors. Each of the two or more U-shaped walls defines an upwardly facing capacitor support surface. Each of the support surfaces has a lower arcuate section extending between left and right end points. The lower arcurate sections have an effective diameter, which is substantially equal to the given diameter of the small capacitor.

Abstract: A condensate drain outlet for a room conditioner of the type which includes a sheet metal basepan having a horizontally extending bottom wall and a rear wall joined to and extending upwardly from the bottom wall in a perpendicular relationship. The rear wall has a substantially U-shaped opening formed therein. A one-piece molded plastic condensate drain insert for insertion into the U-shaped opening includes a mounting plate having a size configured to overly the U-shaped opening in the rear wall and having an opening extending therethrough. A tubular section, having an axial opening extending therethrough, extends from one side of the mounting plate. A U-shaped section extends by a distance greater than the thickness of the rear wall from the other side of the mounting plate. The U-shaped section has an open back, and an inner surface which is in fluid communication with the opening in the plate and the opening in the tubular section.

Abstract: A room air conditioner of the type having a partition, which divides the indoor and outdoor sections of the air conditioning unit. The partition has an exhaust opening for exhausting room air into the outdoor section. An improved exhaust and control arrangement includes a scroll structure mounted in the indoor section for directing conditioned air into the space to be cooled. The scroll structure has a rear wall in confronting relation with the partition and has an exhaust opening therein in fluid communication with the indoor section side of the exhaust opening in the partition. Support structure is provided in the indoor section located laterally of and forwardly of the exhaust opening in the partition. The partition is provided with a second opening therethrough adjacent the support structure. A one-piece exhaust actuation device includes an elongated actuating arm.

Abstract: An electric appliance in a control box mounted within the appliance. The appliance has a planar support wall, which includes first and second mounting rails carried by the support wall. Each of the mounting rails includes an L-shaped structure having a first leg attached to the wall and a second leg supported by the first leg in spaced parallel relationship with the wall. The free edges of the first and second mounting rails are configured to face one another in parallel spaced relationship with one another. The control box is provided with a planar mounting wall, which has a first rail engaging structure formed thereon which is configured to be slidingly received in the space between the second leg of the first mounting rail and the planar support wall. The planar mounting wall includes a second rail engaging structure, which is configured to be slidingly received in the space between the second leg of the second mounting rail and the support wall.
