Abstract
A gas cooking range includes a number of energy-efficient features. The range includes an oven section in which combustion air is preheated by heated discharge gases. Panels are spaced from the walls of the oven and circulation fans are included to provide exceedingly effective airflow within the oven. A gas shutoff valve automatically controls the discharge of heated gases from the oven so that heated gases are discharged only when combustion is occurring. The range also includes a compact, rotatable oven/broiler burner unit, a smoke-free drip pan, an efficient piloted ignition, flame-containing rangetop burner rings atop which pots and pans can be supported, and a small, portable oven which can be supported atop the burner rings.
Claims18
In a gas cooking range, the combination comprising:
- (a) an oven compartment;
- (b) a broiler compartment located beneath the oven compartment;
- (c) a burner element located near the interface between the oven compartment and the broiler compartment, the burner element movable from a first position where heat is directed primarily toward the oven compartment to a second position where heat is directed primarily toward the broiler compartment;
- and
- (d) means for moving the burner element between the first and second positions.
In a cooking range, the combination comprising:
- (a) an oven having a flue vent for the discharge of heated gases from the oven;
- (b) a heating means for the oven, the heating means being in the form of a gas burner;
- (c) a closure member for the flue vent, the closure member movable from a first position where heated gases are permitted to be discharged from the oven and a second position where heated gases are retained within the oven;
- (d) a control for the heating means, the control being disposed in a gas line supplying the heating means and permitting the heating means to be selectively activated, the control being operated by gas pressure in the gas line;
- and,
- (e) an interconnected between the flue vent closure member and the heating means control, the interconnection causing the closure member to move to the first position when the heating means is heating the oven, and causing the closure member to move to the second position when the heating means is not heating the oven.
In a gas cooking range, a means to constrain and direct the flame emitted by range-top burners, comprising an upstanding ring adapted to be disposed circumferentially about a given burner, the ring including vertically extending slots to enable the ring to be fitted about a grid-like pan support having radially extending members, the ring including at least one vent opening for the entrance of air for combustion, and a laterally outwardly extending flange located at the upper periphery of the ring, the flange adapted to maintain generally surface-to-surface contact with the underside of a pan.
In a cooking range having a waist-level oven and an eye-level oven, the combination comprising:
- (a) a flue vent for the discharge of heated gases from the waist-level oven;
- (b) a first passage in communication with the flue vent for conducting heated gases from the flue vent to the atmosphere;
- (c) a second passage in communication with the flue vent for conducting heated gases from the flue vent to the eye-level oven;
- and,
- (d) a diverter valve for controlling the discharge of gases either to the atmosphere or to the eye-level oven.
In a gas cooking range, the combination comprising:
- (a) an oven compartment;
- (b) a broiler compartment located beneath the oven compartment;
- (c) a burner element located near the interface between the oven compartment and the broiler compartment, the burner element including components movable from a first position where heat is directed primarily toward the oven compartment to a second position where heat is directed primarily toward the broiler compartment;
- (d) a flue vent for the discharge of heated gases from the oven compartment;
- (e) a closure member for the flue vent, the closure member movable from a first position where heated gases are permitted to be discharged from the oven and a second position where heated gases are retained within the oven;
- (f) a control for the burner element, the control permitting the burner element to be selectively activated;
- (g) an interconnection between the flue vent closure member and the burner element control, the interconnection causing the closure member to move to the first position when the burner element is heating the oven, and causing the closure member to move to the second position when the burner element is not heating the oven;
- (h) a first passage in communication with the flue vent to convey heated gases away from the oven;
- (i) a second passage for the intake of air into the oven;
- (j) the first and second passages being located in heat exchange relationship with each other so that intake air for the oven is preheated;
- (k) a plurality of panels disposed within the oven, the panels forming an enclosure spaced a small distance from the sides of the oven, the panels providing an area of relatively poor heat conductivity between the panels and the oven walls and an area of relatively uniform temperature distribution within the enclosure;
- and,
- (l) a fan disposed inside the oven for circulating heated gas within the oven.
