A convection oven having a vapor collection system; water injection system; easily accessible electrical components; and a variable-speed, reversible blower is disclosed. The vapor collection system collects vapor from the cooking chamber during a cooking event, condenses the vapor, and drains the condensed vapor. The water injection system injects water for impact against a blower wheel for dispersion into the air circulating through the cooking chamber. The electrical components are housed within a housing that in a closed position conceals the components and in a closed position exposes the components for easy access. The rotational speed and direction of the variable-speed, reversible blower is controlled during a cooking event according to predetermined speed curves which may include one or more reversal events to achieve more uniform cooking of food. A main controller is programmable via an operator input (e.g., liquid crystal display touch screen) to control operating parameters of the oven.

A cooktop burner assembly is described. The cooktop burner assembly includes a main burner, and a simmer burner located below the main burner, where a diameter of the simmer burner is greater than a diameter of the main burner. The closer placement of the main burner to a cooking vessel placed on top of the cooktop burner assembly as compared to the placement of the simmer burner from the cooking vessel increases thermal efficiency. Moreover, the farther placement of the simmer burner from the cooking vessel facilitates simmering of items in the cooking vessel and the larger diameter of the simmer burner reduces a possibility of overheating the main burner and the cooking vessel.

In certain embodiments, a dual fuel heater has a pressure regulating device for selectively coupling with a first source or a second source operating at different pressures. The dual fuel heater can also include first and second fuel lines, a fluid flow controller, a combustion chamber and first and second oxygen depletion sensor nozzles. The fluid flow controller is configured to selectively permit flow of fuel to either the first fuel line or to the second fuel line. In some embodiments, the first fuel line is connected to the first oxygen depletion sensor nozzle and the second fuel line is connected to the second oxygen depletion nozzle.

A cooking apparatus to change the direction of hot air to be fed into a cooking chamber. The cooking apparatus includes a cooking chamber, a hot-air feeder to feed hot air into the cooking chamber, and an air-direction regulator to change a direction of the hot air fed from the hot-air feeder.

A portable cooking kit, apparatus and method is usable for moderating heat from an intense heat source, such as an outdoor grill or 1. The apparatus includes a food support member, including a perforated panel surrounded by a rim. The food support member rests on top of a heat shield made from a heat-tolerant material. During use, the heat shield is stably suspended over direct, intense heat from a heat source. The food to be cooked is placed on the food support member, and the food support member may then be placed on top of the heat shield. By buffering the direct heat from the heat source, the heat shield allows food placed on the food support member to cook, but protects the underside of the food from becoming scorched. Optionally, a dome-shaped cover may be used to cover both the food support member and the heat shield.

A cooking apparatus is provided having an apparatus body including a burner which heats an object. There may be a first image acquirer provided at one side of the apparatus body, the first image acquirer may be configured to acquire image information corresponding to a heat source generated by the burner. Additionally, a display may be provided at one side of the apparatus body to display the image information acquired by the first image acquirer.
