' 7 Claims. (Cl. 62-262) ABSTRACT OF THE DISCLOSURE The invention resides in an air conditioning unit for installation in both sliding and double-hung windows in which a common base is provided for evaporator and compressor cabinet structures located on opposite sides of the window. A slot in the common base terminates at a narrow, reinforced corner common to the sections spaced by the slot. The evaporator and compressor cabinet structures are carried upon the two sections and functionally connected to each other across the common reinforced corner by conduit structure.
Heretofore, it has been proposed to partially divide the cabinet structure of a window air conditioning unit in such a manner that a part of the window structure could be disposed within the profile of the cabinet. In the Lipman Patent No. 2,604,763 such a unit is shown adapted to a double-hung window. The Deering Patent No. 2,610,483 shows a unit for a casement window in whichthe condenser section is partially divided to accommodate a vertical mullion between two unglazed lights. However, the arrangements of these two patents are not adaptable to horizontally sliding windows.
According to the invention, the advancement in the art of window air conditioners is characterized by a split chassis having a condenser section and an evaporator section in spaced relation except for a narrow relatively rigid common connector located between said sections and disposed adjacent the corners thereof. When installed in a window having a sliding sash, the sliding sash, when substantially closed, islocated between the condenser and evaporator sections and abuts the common connector. A suitable filler seals the narrow opening'between the sliding sash andthe window frame which results from the interference of the common connector. In the vertical projection of the common connector are housed the electrical, refrigerant, condensation and air connections extending between the evaporator and condenser sections.
More specifically, the invention takes the form of a relatively flat, rigid sheet metal chassis or base having two spaced pan sections each having a rigid reinforcing common connector in one corner. The edges of the spaced sections are flanged for rigidity, as are the edges of the common connector which is preferably a box section. The spaced pan sections provide support for the evaporator condenser structure and the housings therefor.
Thus, an object of the invention is to provide an air conditioning unit specially adapted for horizontally sliding windows which is sufiiciently rigid to enable the same to be handled during transportation and to be installed by homeowners and other unskilled persons, with the overhanging condenser section capable of being conveniently supported from the sill.
Another object is to provide an air conditioning unit which lends itself to installation in both horizontally sliding and double-hung windows.
A further object is to provide an air conditioning unit which is conveniently adapted for use with sliding windows as well as being adapted for installation in walls and bulkheads and is of such a design that maximum heat and sound insulation takes place between the evaporator and condenser sections.
A still further object of the invention resides in the provision of a split, twosection, sheet metal base, each section having a common connector at one corner which reinforces the spaced sections of the base upon which the evaporator and condenser housing and associated mechanism of an air conditioning unit are carried.
These and other objects and advantages will more fully appear from the following specification and appended claims:

FIG. 8 is a view similar to FIG. 7 taken on line VIIIVIII of FIG. 1 showing the seal between the fixed and sliding sashes of the window.
FIG. 9 shows the sill mounting detail of the unit shown in FIG. 1, I
FIG. 10 shows the unit of FIG. I mounted in a doublehung window, and
FIG. 11 shows the sealing strip used when the unit of FIG. 1 is installed in a double-hung window.
Referring to FIG. 1, a conventional sliding window 10 is shown having a fixed sash 12 and a horizontally sliding sash 14. An air conditioning unit '16 is shown positioned in the window 10 with the sash 14 substantially closed, the narrow vertical opening between the end 18 of the sash 14 and the frame 19, caused by the interference of the reinforcing corner structure, generally designated 20, of the unit 16 being shown sealed by a suitable filler means, generally indicated at 22.
As shown in FIG. 2, the unit 16 comprises an evaporator housing 24 and a condenser housing 26 carried upon a chassis or base structure having a common connector which partially defines a reinforcing corner structure generally designated 20 in FIGS. 1 and 2.
The main structural base member for the support of the housings 24 and 26 and the conventional refrigerating apparatus disposed therein preferably takes the form of a one-piece sheet metal split pan 28 having drawn flanges 30 and lanced and turned flanges 32, 34 and 36. The sections 38 and 40 of the pan 28 are attached by a common connector portion 42 disposed at one corner of each of the rectangular sections 38 and 40, the portion 42 being one of the structural elements of the reinforcing corner structure of sections 38 and 40.
To reinforce the portion 42 and the flanges 30 and 36 directly adjacent thereto, a sheet metal part, generally designated 44, of the shape shown in FIG. 4 is provided. As shown, the part 44 comprises two similar parallel angle portions 46 and 48 having a common connecting web 50 with a vertical flange 52. Integral with the portions 46 and 48, and located on the vertical legs thereof, are attachment flanges 54.
In FIG. 5 the part 44 of FIG. 4 is shown welded in position, the flanges 54 being welded to the adjacent flange 30, the flange 52 being welded to the flange 36 and the angle portions 46 and 48 being welded to the flanges 32 and 34 as well as to the pan 28. In this manner, a rigid, six-sided box section is provided in the region of the common connector portion 42 of the pan 28.
As shown in FIG. 4, the part 44 is preferably provided with opening 56 to accommodate the condenser drain tube 58 extending between the evaporator and condenser sections of the unit 16 (see FIG. 6).
Substantially within the vertical projection of the web 50 of the reinforced corner structure is preferably located the refrigerant tube 60 and the air vent conduit 62. A suitable inverted U-shape cover 64 is shown masking the tube 60 and conduit 62 as well as the part 44, the cover 64 also functioning to fill the space between the housings 24 and 26 in the region of the reinforced corner structure. A screw 66 is shown holding the cover 64 to the flange 30.
To reduce the vertical dimension of the structure above the portion 42 of the pan 28 to a minimum, the air ye- 62 may be omitted and the refrigerant tube 60 may be inserted in holes provided in the part 44 in the same manner as the drain tube 54. Similarly, the conduit 68 for the electrical conduit may be lowered into the profile of the part 44. For a more complete disclosure of the air vent 62 and its associated adjustment structure, reference mm be had to copending application Ser. No. 586,865, filed Oct. 14, 1966.
To seal the openings between the sash 14 and the frame 19, as well as between the sashes 12 and 14, caused by the interference of the corner structure 20, a suitable filler strip 70 is provided with grooves 72 in which to receive and support the sealing strips 74 which engage with the edge 18 and frame 19 (see FIG. 7), the lower end of the strip 70 resting on the top of the cover 64 and the strips 74 extending along both sides of the cover 64. As shown in FIG. 8, a vertical sealing strip 76 seals the vertical space 78 between the sashes 12 and 14. A sealing strip is also provided between the portion 42 of the pan 28 and the channel of the window frame in which the sliding sash operates.
FIG. 9 shows one manner of supporting the unit 16 on the window sill. As illustrated, support brackets St are located at opposite sides of the condenser portion and attached to the pan section 38 by a cap screw 82. Lag-screws 84 attach the brackets 30, at the proper height, to the sill 86 while each adjusting screw 88, threaded in the brackets 80, abuts the sill 86 to take the torque. In practice, the entire weight of the unit 16 may be carried on the brackets 80 with the evaporator portion of the unit 16 slightly spaced above the stool 90.
By retaining the vertical dimension of the reinforcing corner 20 to a minimum, the unit 16 is well adapted for installation in double-hung windows as well as horizontally sliding windows. Such use is shown in FIG. wherein the lower sash 92 of the double-hung window 94 is shown lowered between the condenser and evaporator housings 24 and 26 with the opening 96 between the window stool and the lower edge of the sash 92 approximating the vertical dimension of the reinforcing corner 20. In FIG. 11 is shown a sealing and filler member 98 having a clearance portion 100 to accommodate the reinforcing corner 29 and fill the opening 96.
It should be understood that the controls 102 for the unit 16 may be located on either the right side of the front panel 104, as shown, or on the left side. Also, the structure constituting the reinforcing corner 20 may be located at the left end of the space between the sections 24 and 26, as shown in FIG. 2, to accommodate a window which slides to the left to close, as shown in FIG. 1, or at the right end for use in a window which slides to the right to close.
