The present utility model discloses an oil-smoke removal device, including an oil-smoke removal device body, which is provided with an air inlet at one end, and an air outlet at the other end, and an absorption and decomposition device for decomposing and absorbing the oil-smoke is provided in the middle of the oil-smoke removal device body. The oil-smoke removal device provided by the present utility model is a structure mainly applied for absorbing oil-smoke during barbecue, and it uses the absorption and decomposition device in the structure to achieve the objective of effective adsorption and decomposition of the oil-smoke contained in the oil-smoke gas, which greatly reduces the environmental pollution caused by oil-smoke emissions, resulting in a very good effect in the practical application.

The present invention relates to an exhaust closure system (10) for a cooking oven. Said exhaust closure system (10) is inter-connectable or interconnected between a top wall (30) of an oven cavity (40) and an exhaust channel. The exhaust closure system (10) comprises a lower casing (12) attachable or attached on the top wall (30) of the oven cavity (40) and including at least one inlet opening (22) in its bottom side. The exhaust closure system (10) comprises an upper casing (14) connectable or connected to the exhaust channel and including at least one outlet opening (24) in its top side. The lower casing (12) and the upper casing (14) are permanently or detachably jointed and form a housing of the exhaust closure system (10). A stationary plate (16) and a sliding plate (18) are arranged inside the housing and between the inlet opening (22) and the outlet opening (24). The stationary plate (16) and the sliding plate (18) lie against each other and include at least one opening (26, 28) in each case. The sliding plate (18) is slidable relating to the stationary plate (16) between a closed state and an opened state. The at least one opening (26) of the stationary plate (16) is covered by the sliding plate (18) in the closed state, while the at least one opening (28) of the sliding plate (18) is covered by the stationary plate (16) in the closed state. The openings (26, 28) of the stationary plate (16) and the sliding plate (18) overlap at least partially in the opened state. Further, the present invention relates to a cooking oven with at least one exhaust closure system (10).

A method and system are provided that include features for operating an appliance in an odor removal cycle. In one aspect, an appliance has a housing defining a sealable volume and includes an ozone generator, an ozone detection device, and a controller. In an odor removal cycle, the controller causes the ozone generator to inject, at a predetermined injection interval, predefined dosages of ozone into the sealable volume of the appliance. The controller monitors the concentration level within the sealable volume after each injection based on inputs received from the ozone detection device. The controller ascertains when the concentration level reaches a maximum concentration level threshold, and when this occurs, the controller can cease the injections and can activate one or more ozone removal devices to remove the ozone from the sealable volume to a safe level.

A cooking apparatus and method for use of the same are disclosed that utilize forced convection and radiant heating cooking. In one embodiment, the cooking apparatus includes an oven housing defining a cooking chamber, a circulation chamber, and a catalyst chamber. The catalyst chamber is superposed to the circulation chamber and the circulation chamber is superposed to the cooking chamber. Heating elements are located in the cooking chamber and the circulation chamber. An airflow circulation loop is located between the cooking chamber and the circulation chamber. An exhaust airflow path is provided from the circulation chamber to the catalyst chamber to an exterior of the oven housing. A fan subassembly is located within the oven housing and the fan subassembly circulates convection air along the airflow circulation loop with a portion of the convection air being diverted into the exhaust airflow path.

A system for electronically controlling a vent damper for a gas oven.

An air cleaning system for an oven that includes a cooking chamber configured to receive a food product includes a catalytic converter, an input array and a preheater. The catalytic converter may be configured to clean air expelled from the cooking chamber. The input array may include perforations through which cleaned air that has been processed by the catalytic converter is provided into the cooking chamber. The preheater may be disposed proximate to the cooking chamber to use heat generated by the cooking chamber to preheat the cleaned air prior to entry of the cleaned air into the cooking chamber through the input array.

An air cleaning system for an oven that includes a cooking chamber configured to receive a food product includes a catalytic assembly and a preheater. The catalytic assembly may be configured to clean air expelled from the cooking chamber. The preheater may be configured to receive hot, cleaned air from the catalytic assembly in an outlet duct to transfer heat to fresh air provided from outside the oven in an inlet duct to preheat the fresh air to heated input air prior to provision of the heated input air into the cooking chamber.

A cooking device includes a catalyst device having a base unit which is made of electrically conductive material and on which a plurality of catalytically active elements or a catalytically active surface coating is arranged. The base unit has electric connection regions which are at least partly made of a pressed material region of the base unit and/or at least partly have an electrically conductive adhesive. An electric energy unit is connected to the electric connection regions of the base unit and supplies the base unit with electric energy for a self-heating of the catalyst device.

A method of controlling a cooking apparatus includes a cleaning process which includes controlling a temperature in a cooking chamber such that the temperature in the cooking chamber is maintained at a preset first temperature for a preset first time, and controlling a temperature in a cooking chamber such that the temperature in the cooking chamber is maintained at a preset second temperature higher than the first temperature for a preset second time.
