3,712,819 PER Jan. 23, 1973 "r. R. FIELD VENTILA'I'ED OPEN-AIR INDOOR BROILER HAVING DAM MEANS AND CONTROL THE FOR Filed Nov 23 1e VENTILATED OPEN-AIR INDOOR BROILER HAVING DAMPER MEANS AND CONTROL THEREFOR Thomas R. Field, 4129 Flamingo W. Drive, Indianapolis, Ind. 46226 Filed Nov. 23, 1971, Ser. No. 201,436 Int. Cl. A47j 37/ 08 U.S. Cl. 99-400 17 Claims ABSTRACT OF THE DISCLOSURE Ventilated open-air indoor broiler having damper means and positionable control therefor comprising an energizing switch for electric heating elements.
BACKGROUND OF THE INVENTION and exhausted therefrom to the atmosphere by ducting (not shown).
The invention herein can be used advantageously, for example, with the broiling apparatus disclosed in U.S. Pat. Nos. 3,444,805 and 3,474,724. The invention is directed to a relationship of a positionable closure or damper at the entrance to a plenum chamber and a physical co operative relationship with electric switch means. Energization of the heating elements and exhaust fan means is prevented when the entrance to the plenum is closed by the damper. Once the damper is opened the switch may be turned for energizing the heating elements and fan means. The damper cannot be lowered for closing the entrance to the plenum as long as the heating elements are energized. This is a safety feature assuring that the damper to the plenum entrance will always be open whenever the heating element is energized, and preventing energization as long as the damper is closed to ventilation.
BRIEF SUMMARY OF THE INVENTION It is an object of this invention to provide a damper for an air ventilated broiler.
It is another object to provide a safety feature whereby whenever the broiler heating elements are energized for broiling, the damper means must be in open position.
It is still another object of this invention to prevent closure of the damper means at the plenum entrance as long at the heating elements are energized.
It is still another object to disclose a back draft damper for preventing reverse flow of outside air through the plenum into a room.
BRIEF DESCRIPTION OF THE DRAWINGS The invention will be more fully understood and further objects and advantages thereof will become aparent when reference is made to the following detailed description of the preferred embodiment of the invention and the accompanying drawings in which:
FIG. 1 is a perspective view of an air ventilated counter top broiler showing the damper means in a position establishing an opening to an air plenum chamber;
FIG. 2 is a cross-sectional view of the broiler shown in FIG. 1; and
FIG. 3 is a perspective view of a control switch knob in position adjacent a damper in closed position.
United states Patent O ice DESCRIPTION OF THE PREFERRED EMBODIMENT The invention is adaptable for use with a broiler arrangement as disclosed in the preferred embodiment disclosed in the drawings; however, it is also adaptable for use with other broiling or cooking arrangements such as disclosed in U.S. Pat. Nos. 3,587,555 or 3,596,650.
Referring to FIG. 1 there is shown in perspective a counter top drop-in open surface broiler identified generally by the numeral 10. A cross-sectional view is shown in FIG. 2. The broiler is comprised generally of the broiling portion and a plenum chamber having power driven fan exhaust means associated therewith. A frame includes a box or chamber 12 defining a recess preferably formed of sheet metal. The box is recessed to the extent of several inches for the purpose of housing broiler and grease collecting component to be described in detail later in the specification. A peripheral portion 14 of the frame surrounds the box and is adapted to overlie an opening in a kitchen counter top 15 and be supported therefrom. Chamber 12 is provided with a plurality of openings. Slotted opening 16 admits cooling air which is drawn therethrough and exhausted through port 21 into air plenum chamber 34. Opening 18 in the bottom of the chamber permits grease and meat juices to fiow into removable jar 32.
Another recessed chamber 19 is received within chamber 12 in fixed spaced relationship with the walls thereof to define insulating spaces 20 through which cooling air may pass for carrying away heat. Chamber 19 is adapted to receive heating or broiling elements 22 just below the top level of the frame. Electrical elements 22 are supported in the position shown in FIG. 2 by an arched wire support member carried above a metal casting 24. The casting in turn is supported above the bottom of chamber 19 by upward protrusions formed in the bottom. Grill 26 overlies the opening in the frame and is disposed above electrical elements 22 for supporting meat in broiling position.
A cross-sectional view of a housing 34, defining an air plenum chamber, is shown in cross-section in FIG. 2. The entrance to the plenum is disposed to one side of and substantially on the level of grill 26.
A damper 36 preferably formed of sheet metal, or as a casting or extrusion, is adapted to be hinged adjacent one side of housing 34. The damper is adapted to be positionable over the entrance to the plenum for the purpose of determining the size of the opening to the plenum chamber of for closing the entrance altogether. As shown in FIG. 2 the damper may be hinged to an upstanding peripheral sheet metal frame 38 at the entrance to the plenum. The damper in the form of a cover is adapted to be received over the peripheral frame for selective closure of the entrance to the plenum. A link bar 40 is connected to damper 36 in a manner for limiting the extent to which the damper can open so that the entrance into the chamber faces across the grill or broiling surface.
As will be noted in FIG. 1, after knob 44 has been rotated to turn its switch to an on position, a portion of the knob interferes with inadvertent closure of the damper.
This amounts to a safety feature so that electrical broiling elements 22 cannot be energized as long as the damper closes the entrance to the plenum. Once the damper has been raised to expose the entrance to the plenum, knob 44 can be turned so as to energize the electrical broiling elements 22 and motor 48 for driving exhaust fan 50. Air is thereby drawn into the entrance of the plenum from across the surface of grill 26 for the purpose of collecting smoke and fumes caused by broiling. These gases are drawn into the plenum and exhausted by fan 50 through ducting for extending through a building wall to the the atmosphere. As long as elements 22 are energized, knob 44 is in the position shown in FIG. 1, and damper 36 cannot be lowered to close the entrance to the plenum. By the arrangement disclosed, as long as elements 22 are energized, exhaust fan 50 will be operating and damper 36 will be open. Additionally, a small amount of air is drawn through vent opening 16 and around and underneath chamber or pan 19 into the plenum at opening 21 so as to cool the chamber and prevent heat build-up sufficient to support combustion. It also prevents excessive heat to be conducted to the kitchen counter top.
