The griddle section is a flat plate. The wok section is a flat plate having an opening within which a wok may be removably retained. The grill section has bars, with open spaces between the bars. The griddle and wok sections are parts of a single flat plate, the grill section is generally coplanar with the flat plate, and the three sections form a generally rectangular or curvilinear shape. The fifth and sixth preferred embodiments of the invention are substantially the same as the first four embodiments, except that the fifth only includes a wok section and a griddle section, with no grill section, and the sixth only includes a wok section and a grill section, with no griddle section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention is cookware combining two or three cooking sections in one unit. In the first preferred embodiment, the three sections are a griddle section, a wok section, and a grill section.
FIG. 1 shows the griddle section 10, which is a flat plate having an upper surface suitable for cooking food such as Mongolian barbecue or Teppan-Yaki.
FIG. 2 shows the wok section 12, which is a flat plate having an opening 14 within which a wok may be removably retained. (A wok is a bowl-shaped cooking utensil commonly used in the preparation of Chinese food by stir frying. Woks are generally circular, and may have flat bottoms with rounded sides and one or two handles.) The opening is preferably circular, so that it will retain the sides of a conventionally shaped wok. A wok may be sold with the invention, or it may be purchased separately.
FIG. 3 shows a wok 16 that may be used in the wok section, having rounded side 18, a flat bottom 20, and a handle 22. (Alternatively, the wok may have a rounded bottom.)
FIG. 4 shown the grill section 24, preferably having parallel members or bars 26 joined at their ends by traverse members or bars 28. There are open spaces 30 between the bars. The parallel bars hold food that is being cooked (e.g., by barbecuing) while the openings allow the food to be in direct contact with fire or heat below the grill section.
FIG. 5 shows a top view of the first preferred embodiment of the invention, in which the griddle and wok sections are parts of a single flat plate 32. The grill section is generally coplanar with the flat plate. The three sections form a generally rectangular shape, with each section adjoining the other two.
FIG. 6 shows a top view of the second preferred embodiment of the invention, which is the same as the first preferred embodiment, except that the griddle and grill sections are on opposite sides of the wok section.
FIG. 7 shows a top view of the third preferred embodiment of the invention, which is the same as the first and second preferred embodiments, except that the wok and grill sections are on opposite sides of the griddle section, and the three sections form a generally curvilinear shape, namely, a circle.
FIG. 8 shows a top view of the fourth preferred embodiment of the invention, which is the same as the third preferred embodiment, except that the three sections form a different curvilinear shape, namely, a kidney shape.
FIG. 9 shows a top view of the fifth preferred embodiment of the invention, which is substantially the same as the first four embodiments, except that it only includes a wok section and a griddle section, with no grill section.
FIG. 10 shown a top view of the sixth preferred embodiment of the invention, which is substantially the same as the first four embodiments, except that it only includes a wok section and a grill section, with no griddle section.
The flat plate comprising the griddle and wok sections, the members of the grill section, and the wok are preferably made of a ferrous metal, such as iron or steel. (The handle of the wok may be made of wood or another suitable material.) In addition to the shapes shown in the drawings, the sections may form any square, rectangular, circular, oval, kidney, polygonal, curvilinear, or other shape.
FIG. 11 is a front elevational sectional view of the second preferred embodiment of the invention along line 9-9 in FIG. 6. (Substantially the same arrangement may be used for the other embodiments.) A common heat source 34, such as propane or other natural gas, is provided for all three sections 10, 12 and 24. Lines 36 carry the gas to burners 38 below each section. The whole apparatus is contained in housing 40 and supported on legs 42. The supply of fuel to each section is preferably controlled separately, as different temperatures may be required to cook food in each section. Alternatively, wood, charcoal or any other fuel, or electrical resistance heating, may be used. The invention is ideally suited for outdoor cooking. However, with sufficient ventilation and safeguards it can be installed in a dwelling house, restaurant or other building for indoor cooking.
It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
