DETAILED DESCRIPTION OF THE DRAWINGS

While the concepts of the present disclosure are susceptible to various modifications and alternative forms, specific exemplary embodiments thereof have been shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that there is no intent to limit the concepts of the present disclosure to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
Referring to FIG. 1, a gas cooking range assembly 10 (hereinafter range 10) includes a lower frame 12 and an upper panel 14. The lower frame 12 includes a number of downwardly extending legs 16 configured to contact a floor of a house (not shown). The legs 16 are located in each corner of the lower frame 12 and are adjustable to allow the user to level the range 10 to compensate for any tilt or angle of the floor.
A housing 18 extends upwardly from the lower frame 12. The upper panel 14 has a laterally extending base 20 that is secured to the housing 18. A lower oven 22 and an upper oven 24 are accessible from the front of the housing 18. The oven 22 has a cooking chamber (not shown) into which pans, sheets, or other cookware carrying food items are placed to be heated. The cooking chamber includes a rack 26 located therein. A door assembly 28 is hinged to the front of the housing 18 and permits access to the rack 26. The oven 22 has a baking element 30 that is configured to provide heat for baking or otherwise cooking food items placed on the rack 26. In the illustrative embodiment, the baking element 30 is a gas-fired bake burner. It should be appreciated that in other embodiments the baking element 30 may be an electric heating element.
The upper oven 24 is positioned above the lower oven 22 and below the base 20 of the upper panel 14. The upper oven 24 has a cooking chamber (not shown) into which pans, sheets, or other cookware carrying food are placed to be heated. The cooking chamber includes a rack 32 located therein. A door assembly 34 is hinged to the front of the housing 18 and permits access to the rack 32. The oven 24 has a baking element 36 that is configured to provide heat for baking or otherwise cooking food items located on the rack 32. In the illustrative embodiment, the baking element 36 is a gas-fired bake burner. It should be appreciated that in other embodiments the baking element 36 may be an electric heating element.
A user may control the operation of the ovens 22, 24 using a control interface 38 located on the upper panel 14 above the base 20. The control interface 38 includes a display 40 and a set of push buttons 42 that are connected to an automated control system (not shown) operable to control the operation of the ovens 22, 24. For example, the user may use the control interface 38 to set a desired temperature for each oven. The automated control system responds by igniting a flame within each of the baking elements 30, 36 and adjusting the flow of gas as necessary to heat the ovens 22, 24 to the desired temperatures. The amount of heat generated in the cooking chambers of each oven is proportionate to the amount of gas flowing to the baking elements 30, 36.
A cooktop 50 is positioned above the upper oven 24. The cooktop 50 is positioned between the base 20 of the upper panel 14 and a laterally extending manifold 52 positioned at the front of the housing 18. The cooktop 50 includes a top surface 54 and a bottom surface 56. A number of gas burners 58 extend through the top surface 54. A burner grate 60 is positioned above each of the gas burners 58, and the burner grates 60 define a cooking surface 62.
As best seen in FIG. 2, the manifold 52 is positioned above the door assembly 34 of the upper oven 24. The manifold 52 has a front surface 64, a rear surface 66, and a lower surface 68 extending from the front surface 64 to the rear surface 66. The bottom surface 56 of the cooktop 50 is coplanar with the lower surface 68 of the manifold 52. The cooktop 50 and the grates 60 are positioned behind the rear surface 66 of the manifold 52. The cooktop 50 extends away from the rear surface 66 of the manifold 52 to the base 20 of the upper panel 14.
A set of knobs 70 are mounted on the front surface 64 of the manifold 52. Each knob 70 has a face 72 with a grip 74 extending outwardly from the face 72. It should be appreciated that in other embodiments each knob 70 may be shaped as a cylinder or oval without a grip 74 extending outwardly from the face 72. Each knob 70 is mounted on the front surface 64 such that the face 72 is parallel to the front surface 64 and perpendicular to the cooking surface 62.
The knobs 70 are operable to control the flow of gas to the gas burners 58. The burners 58 are configured to generate controlled flames that may be used to heat cooking utensils (i.e., pots and pans) placed on the grates 60. The burners 58 and grates 60 are arranged on the cooking surface 62 such that a user can simultaneously heat pots, pans, skillets, and the like. The magnitude of the flame generated by the burners 58 is proportionate to the amount of gas flowing to the burners 58. A user may adjust the flow of gas to the burners 58 using the set of knobs 70 that are mounted on the front surface 64 of the manifold 52. As the user rotates each of the knobs 70, a gas control valve (not shown) changes the amount of gas flowing to the corresponding burner 58.
Referring now to FIG. 3, the range 10 is shown with a different embodiment of a manifold (hereinafter referenced as a manifold 152). Some features of the embodiment illustrated in FIG. 3 are substantially similar to those discussed above in reference to the embodiment of FIGS. 1 and 2. Such features are designated in FIG. 3 with the same reference numbers as those used in FIGS. 1 and 2.
The laterally extending manifold 152 is positioned above a door assembly 34 of an upper oven 24 at the front of a housing 18. The manifold 152 has a front surface 164 and a lower surface 168 extending from the front surface 164 to a rear surface (not shown) of the manifold 152. A bottom surface 56 of a cooktop 50 is coplanar with the lower surface 168 of the manifold 152. The cooktop 50 is positioned between the manifold 152 and a base 20 of an upper panel 14. The cooktop 50 and a number of burner grates 60 are positioned behind the rear surface of the manifold 152. The cooktop 50 extends away from the rear surface of the manifold 152.
A set of knobs 170 is mounted on the front surface 164 of the manifold 152. Each knob 170 has a face 174 with a grip 172 extending outwardly from the face 174. It should be appreciated that in other embodiments each knob 170 may be shaped as a cylinder or oval without a grip 172 extending outwardly from the face 174. Each knob 170 is mounted on the front surface 164 such that the face 174 is parallel to the front surface 164 and at an angle relative to a cooking surface 62, which is defined by the number of grates 60, which are positioned above each of a number of gas burners 58.
There are a plurality of advantages of the present disclosure arising from the various features of the method, apparatus, and system described herein. It will be noted that alternative embodiments of the method, apparatus, and system of the present disclosure may not include all of the features described yet still benefit from at least some of the advantages of such features. Those of ordinary skill in the art may readily devise their own implementations of the method, apparatus, and system that incorporate one or more of the features of the present invention and fall within the spirit and scope of the present disclosure as defined by the appended claims.
