The present disclosure is directed to a multi-heat source apparatus. The multi heat source may include a fire pit and is configured to provide ambient heating with both convection heat transfer and radiation heat transfer. The multi-heat source apparatus comprises an infrared emitter for generating infrared radiation. The multi-heat source apparatus comprises a shielding member between a heat source for the convection heat transfer and another heat source for radiation heat transfer.

An electric and gas dual-purpose frying oven includes a shell, door body, oil receiver, synchronous motor, a motor bracket, a sub-clutch and a mother clutch, a grill frying pan, and a frying pan cover, an infrared gas burner and a gas valve. The shell is composed of a control chamber with the front opening and the top opening and a holding chamber with the back lower part. An inlet groove and a pivot joint groove are arranged on the baking chamber. The model comprises an electric heating pipe having a head of the tube body and a seat plate part. The baking cavity is provided with a socket hole. The pipe extends into the baking cavity through the socket hole.

A cooking appliance including a cooking chamber for cooking food items, the cooking chamber having a base, at least one wall and a door. A smoke generator is provided in the cooking chamber, the smoke generator made up of a smoke generation compartment in the base, a wall or the door of the cooking chamber and an igniter in, or installable in, the compartment. A fluid injector may be provided to inject a combustion-enhancing fluid such as air into the compartment. Combustible material, such as wood chips, is added to the compartment, covered by a vented compartment lid and then an automated process ignites the wood chips and feeds combustion-enhancing fluid to the compartment to maintain combustion and generation of smoke for smoking the food items.

A burner assembly is disclosed including a burner head for generating heat via an electrical heating element and an annular burner head surrounding the burner head for generating heat via the burning of a gas/air mixture. The burner head may be used for simmering with the electrical heating element including a silicon nitride element for generating the low heat required for simmering. The annular burner head may be used for generating more heat than the burner head.

A method of operating an oven appliance includes obtaining a temperature set point, determining, based on the temperature set point, an electric heating temperature range and a gas undershoot temperature limit, the gas undershoot limit being below the electric heating temperature range, determining that a chamber temperature of the oven appliance has dropped to the gas undershoot temperature limit, and operating a gas heat source to maintain the chamber temperature above the gas undershoot temperature limit.
