A speed cooking ovens is disclosed comprising a cooking cavity, thermal heating source, air movement and directing means, air flow control means, an air delivery means, and a vent assembly. The speed cooking oven may additionally utilize air flow control mechanisms and be practiced as a single rack speed cooking oven or a multi rack speed cooking oven. Hot gas is circulated to and from the oven cavity via air delivery means, such that turbulently mixed glancing, conflicting and colliding air flows mix at and about the surfaces of the food product. The turbulently mixed air flows are spatially averaged over the surface area of the food product producing high heat transfer and moisture removal rates, thereby optimizing speed cooking of the food product.

A combination heat and steam oven according to the present invention includes a housing having an internal heating compartment, at least one dry heating element disposed within the heating compartment, a steam generating unit configured to produce steam for injection into the heating compartment, and a user interface. The user interface is configured for selectively controlling operation of the at least one dry heating element and the steam generating unit, so that the steam generating unit and the at least one dry heating element may be operated alone or simultaneously with the other of the steam generating unit and the at least one dry heating element.

An appliance is rendered self-cleaning of accumulated organic contaminants on one or more surfaces of the appliance, by coating such surfaces of the appliance with a photocatalytically-activated self-cleaning coating. Upon exposing such coated surfaces to radiation of the appropriate wavelength, for a sufficient interval of time, at least a portion of the organic contaminants present on the photocatalytically-activated self-cleaning coating are removed. The coated surface is thereby cleaned without the need of manual effort or high temperatures. The radiation is generally actinic radiation, and more particularly includes ultraviolet radiation.

An oven rack assembly including full extension slides. Full extension slides are mounted to an oven rack and oven rack frames or wire racks providing full extension of an oven rack from an oven enclosure. The rack frame is mounted to oven walls or the slides are coupled to wire racks along oven slide walls.

A combination cooking oven is disclosed comprising a cooking cavity, a controller, thermal heating source, blower assembly, air directing means, deflecting means and a vent assembly wherein speed cooking or slower cooking of food products may be accomplished within the same appliance by movement of a gas baffle.

A method and apparatus for cleaning a cooking apparatus. A self-cleaning cooking apparatus can include a cooking chamber having a plurality of surfaces a food preparation assembly configured to prepare food product within the cooking chamber, a water nozzle positioned to direct water into cooking chamber, a holder configured to hold a detergent packet in a position configured to allow the water to dissolve the detergent from the detergent packet. The holder can be positioned in a drain tank or within the cooking chamber. The liquid within the drain tank can be re-circulated from the drain tank to the nozzle.

A system for controlling temperature in an enclosure operates in a low heat or a high heat mode with flame always present. The presently intended use is for providing a cooking grill with a controlled temperature cooking space. An electrically controlled valve having high flow rate and low flow rate settings is interposed in the fuel line for at least one of the burners in the grill. A temperature sensor signals cooking space temperature to a controller that may be a microprocessor. The system includes a keyboard allowing the user to communicate a selected set point to the microprocessor and the microprocessor communicates status to a display. The microprocessor selects the setting of the electrically controlled valve. In a preferred embodiment, the electrically controlled valve is placed in series fuel flow with one of the manually adjustable valves commonly found on cooking grills.

A convection steam cooking device utilizes forced recirculation of gases along a primary recirculation path that extends through a steam chamber so that gases from the cooking cavity flow through the steam chamber and are subjected to a “steam bath” that alters the gases by adding heat and/or moisture. The cooking device includes a cooking cavity, a fan, a steam chamber disposed beneath the cooking cavity with a lower pool area for holding water and an upper steam collecting area disposed directly above the pool area, and a removable baffle disposed between the cooking cavity and the steam chamber with a perforated section remote from the fan and disposed at an upward angle. The primary forced recirculation path extends from the main cooking cavity, through the baffle, substantially across the steam collecting area, through a duct to the fan, and back to the main cavity.

The cleaning-friendly article, such as a household kitchen appliance, which is suitable for heating food and/or directly connected with this unit, has a suitable long-lasting or permanent easily cleaned coating on its surfaces that are accessible to dirt. In order to provide this easily cleaned coating a mixture is applied to these surfaces, which contains a hydrolyzable, network-forming gel and a hydrophobic substance. The gel is preferably formed from metal oxides. such as SiO₂, Al₂O₃, Fe₂O₃, In₂O₃, SnO₂, ZrO₂, B₂O₃ and/or TiO₂. The hydrophobic substance is preferably chemically combined with the gel network. The hydrophobic substance preferably includes pre-condensed fluoroalkyl-silanes.

Disclosed herein is an oven that is capable of discharging hot air generated when cooling a door and heat generated in a cooking chamber through the lower end of the door. The oven includes a door having at least two separated air channels. The air channels comprise at least one first air channel to discharge hot air generated when cooling the door through the lower end of the door, and at least one second air channel to introduce air through the lower end of the door such that the door is cooled. In the housing is mounted a circulating fan. Between the circulating fan and the air channels is connected a channel connecting unit. As the circulating fan is rotated, air flows along the second air channel to cool the door. Hot air generated when cooling the door is introduced into the first air channel through the channel connecting unit, and is then discharged out of the oven through the lower end of the door.

An outdoor oven may have a cooking chamber defined by six sides. Each of the six sides may be insulated. A front side may have a door for access to the cooking chamber. The cooking chamber may have a baffle and a cooking plane above and separated some distance from the baffle. Heat in the form of a flame may enter the cooking chamber. The baffle may prevent heat from the flame from directly contacting food on the cooking plane, may inhibit heat transfer through the baffle, and/or may direct heated air around the baffle. The heat is circulated through the cooking chamber to heat the food, and exits a vent positioned below the cooking chamber. An outdoor cooking system may include a burner, a support structure and a fuel supply.

An outdoor gas barbecue grill having an electric self-cleaning unit. The gas barbecue grill includes a grill housing, a grill cover, and a lower grill housing for receiving a gas burner and a cooking grate member. The underside of the cooking grate member includes a plurality of heating members made of metal attached thereto. One of the walls of the lower grill housing includes an electric self-cleaning heating unit mounted thereon and includes an electrical conductor member having a plurality of heating elements for detachably connecting to the plurality of heating members on the cooking grate. During a self-cleaning cycle, the heating members are heated to at least 500° F. in order to burn-off and clean the encrusted and burnt food residues on the cooking grate member for sanitizing the cooking grate member. The grill housing further includes a grill lock connected to the grill cover and to the lower grill housing for locking the grill cover relative to the lower grill housing in order to maintain and control the heat production (ΔH) within the closed gas grill for cleaning the cooking grate member during a self-cleaning cycle. Further, one of the walls of the lower grill housing includes an exhaust fan being attached thereto for venting and dissipating the vaporized fumes to the outside air from the burning of the encrusted food residues on the cooking grate member during the self-cleaning cycle.
