United States Patent 2,993,428 RANGE noon WITH A REVERSIBLE BLOWER PANEL Peter C. Wermager, Hartford, Wis., assignor to Broan Mfg. Co. Inc., Hartford, Wis., a corporation of Wisconsin I v Filed June 26, 1957, Ser. No. 668,156
6 Claims. (Cl. 98-115) This invention relates to a range hood with a reversible blower panel.
Depending upon the architecture of the building, kitchen layout, cabinet construction and other factors, the blower fan used with a range hood may require positioning at one end or the other of the hood. Moreover, the range hood may be required to adapt to a blower duct which may be either rectangular or circular in outline.
It is the object of the present invention to provide a range hood with a blower panel having knock-outs of dissimilar outline disposed near its respective ends and including means for reversing the panel with respect to the hood to selectively register the appropriate knock-out with its corresponding blower duct regardless of the end of the hood near which the blower duct is disposed.
In the preferred embodiment of the invention herein disclosed, the blower duct is supported on a cabinet beneath which the range hood is disposed and on bracket means out of vibration transmitting contact with the range hood.
Other objects and advantages of the invention will appear in the following disclosure in which:
FIG. 1 is a perspective view of a range hood embodying the invention.
FIG. 2 is a perspective view of a blower panel disassoci-ated from the range hood.
FIG. 3 is a plan view of the range hood shown in FIG. 1.
FIG. 4 is a vertical cross section, partly in elevation, taken through a range hood embodying the present invention in operative association with a cabinet and a blower having a rectangular duct.
FIG. 5 is a view similar to that shown in FIG. 4 but in which the blower has a duct which is circular in outline and is disposed near an end of the range hood opposite that shown in FIG. 4.
FIG. 6 is a transverse cross section taken through the device of FIG. 5 and along the line 6-6 of FIG. 5.
The range hood 10 is adapted to be mounted beneath a wall cabinet 11 over a conventional cooking stove or the like. The hood 10 is conventionally fabricated of sheet metal and may comprise a rectangular box portion 12 enlarged forwardly by a flaring canopy 13 which increases the area of interception of the hood. The undersurface of the hood is left open and the top of the box 12 is provided with marginal flanges 14, 15 within which there is an opening 16 closed by the removable and reversible panel 17.
Near one of its ends the panel 17 is provided with a rectangular knock-out 20 and near its other end it is provided with a circular knock-out 21. The knock-outs may be of any convenient configuration, those illustrated being typical.
The panel 17 is mounted on the flanges 14, 15 in any suitable manner. In the disclosed embodiment the flanges 14, 15 are provided with openings 22 which register with like openings 23 in the panel 17 and through which bolts or sheet metal screws 24 may be engaged to secure the panel to the marginal flanges 14, 15. The openings 22, 23 are symmetrical with respect to the opening 16 and to its longitudinal center line AA and its transverse center line B-B whereby the panel 17 2. maybe reversed. In FIGURE 1, the panel is shown with the rectangular opening 20 disposed toward the left and in FIGURE 2. the panel is shown reversed with the rectangular opening 20 disposed toward the right. Regardless of the position of the panel, its mounting holes 23 will register with the holes 22 in the flanges 14, 15.
in the panel 17 exposed when'the knock-out "20 is removed therefrom.
,KnOck-Out 21 remains in place and gas impelled by the blower 25 'will pass upwardly throughfthe range hood through thealigned' openings 31, 30 and into the duct 26. The duct 26 is mounted by the brackets 32 upon the floor 27 and there is a slight spacing between the duct 26 and the panel 17 to maintain these parts out of vibration transmitting contact.
In FIGURE 5, the floor 27 is provided with a circular opening 33 to receive the circular duct 34 of the blower 35. Duct 33 aligns with the opening 36 left in the panel 17 upon removal of the knock-out 21. In this embodiment the knock-out 20 of panel 17 is left in place. Accordingly, the gas impelled by the fan 35 will pass through the aligned openings 33, 36 into the duct 34. Brackets 37 mount the duct 34 on floor 27 in spaced relation to and out of vibration transmitting contact with the panel 17.
1. The combination with an elongated range hood adapted for use with one blower or another blower having ducts of dissimilar outline and which may optionally be disposed near either end of said hood, said hood having an opening of a panel closing said opening and having knock-outs of correspondingly dissimilar outline disposed near its respective ends, and means permitting said panel to be reversed in position with respect to said hood opening to permit the selective registration of an appropriate knock out with a corresponding blower duct regardless of the end of the hood near which the blower duct is disposed.
2. The device of claim 1 in which said means comprises a seat about said opening against which said panel is fastened and complementary fastening means on said seat and panel symmetrically disposed with respect to said opening for reversibility of said panel.
3. The device of claim 1 in further combination with a cabinet to which said range hood is fastened and a blower having a duct in said cabinet, said cabinet being provided with means for mounting said blower duct out of vibration transmitting contact with said panel.
4. The device of claim 3 in which the first mentioned means comprises a seat about said opening against which said panel is fastened and complementary fastening means on said seat and panel symmetrically disposed with respect to said opening for reversibility of said panel.
5. In a ventilating range hood adapted for use in connehtion with an exhaust fan unit for collecting and exhausting the fumes and smoke from a cooking range; an elongated hood housing having at least a backwall, a pair of side walls and a front wall defining an enclosure, a planar top panel member removably mountable to afiord a top wall for said hood, the larginal edges of said top panel connected to at least two of said walls, said top panel having a plurality of readily removable knockout blanks of varying sizes and shapes which are such as to provide spaces for accommodating in one or the other thereof an exhaust fan unit, and said top panel being readily reversible to reverse the positions of said knockout blanks.
6. A ventilating range hood comprising an elongated sheet metal housing defined by a back-wall, a pair of straight rear side walls, a pair of inwardly and forwardly inclined front'side walls, a front wall and a frontjtop' wall, all of said walls cooperating to afiord an enclosure,
and a removable rear planar top panel reversibly mount References Cited in the file of this patent UNITED STATES PATENTS 2,028,509
