A cooking appliance apparatus includes a fan unit, a sensor unit designed to detect an electrical fan parameter of the fan unit, a filter unit allocated to the fan unit, and a control unit designed to determine a filter parameter of the filter unit in dependence upon the fan parameter.

A cooking device includes a cooking chamber wall delimiting at least partially a cooking chamber for receiving food to be cooked. A fan generates a cooling air flow for cooling an outer side of the cooking chamber wall such as to produce an intake region, in which there is a negative pressure in relation to a surrounding area, and a blow-out region, in which there is an excess pressure in relation to the surrounding area. A short-circuit device generates a short-circuit air flow between the blow-out region and the intake region, thereby generating a pressure-neutral region. The cooking chamber wall has a vapor outlet in communication with the cooking chamber for discharging vapor from the cooking chamber into the pressure-neutral region.

A cooking appliance includes a main body forming a machine room; a cooking chamber arranged below the machine room; an intermediate flow path including a first suction port and formed between the machine room and the cooking chamber; and a fan configured to suction air into the intermediate flow path, wherein the machine room includes a second suction port through which air is suctioned, and an opening portion connected to the intermediate flow path, the opening portion includes a first opening portion and a second opening portion arranged at a farther distance from the fan than the first opening portion, and the second opening portion has an area larger than an area of the first opening portion.

A ventilation system for an oven is provided. The system includes a rear duct assembly. The rear duct assembly includes vertical walls defining a vertical air flow path along a rear of the oven, and a separator plate dividing the vertical air flow path into a first air flow configured to receive air from oven electronics and a second air flow configured to receive air from an oven cavity. The separator plate extends vertically downward between the vertical walls from the top of the vertical air flow path a portion of the height of the oven until a mixing zone at the rear of the oven into which the first and second air flows combine into a combined air flow.

A motor-actuated actuated-vent-valve is configured to operatively couple to a vent port of a solid-fueled cooker. The vent port is in series with both a flow of air into a combustion region of the cooker, and a flow of resulting combustion gases from the cooker, the flow of air being responsive to a position of the actuated-vent-valve. A first controller adapted to receive a sensed-temperature signal responsive to a temperature within a cooking region of the cooker, and operatively coupled to an externally-located actuator motor of the motor-actuated actuated-vent-valve, provides for automatically electronically controlling the position of the actuated-vent-valve to a continuum of positions within a range of the positions, thereby substantially regulating the first temperature within the cooking region of the solid-fueled cooker to a user-defined temperature level responsive to the sensed-temperature signal by controlling an exclusively-naturally-occurring flow of air into the combustion region of the cooker.

A ventilation system for an oven is provided. A side duct assembly includes a substantially vertical exit duct portion adjacent to an oven cavity wrapper defining an oven cavity of the oven, the substantially vertical exit duct portion having an air intake configured to receive a cavity air flow from an air intake along a side of a cavity wrapper. The side duct assembly further includes an angled duct portion defining an air passage angled upwards and towards a rear of the oven, the angled duct portion having an input end configured to receive the cavity air flow from the top of the substantially vertical exit duct portion and an output end configured to provide the cavity air flow into a mixing zone at the rear of the oven for mixing the cavity air flow with an electronics air flow from oven electronics into a combined air flow.

A method of operating a heating device includes heating air in a heating device chamber. The method further includes exhausting outgoing air from the heating device chamber via a first flow path through which the outgoing air flows in a first direction, and supplying incoming air to the heating device chamber via a second flow path through which the incoming air flows in a second direction opposite to the first direction. The latent heat in the outgoing air in the first flow path is transferred to the incoming air in the second flow path thereby condensing water vapor contained in the outgoing air to produce liquid water.

Baking oven for preparing food, comprising a housing in which a baking chamber is provided, a first heating device which is provided in the upper area of the baking chamber, a second heating device which is provided in a lower area of the baking chamber and a circulating air unit. The circulating air unit is provided on a first side wall of the baking chamber, and a fan motor of the circulating air unit is integrated into a side area of the housing, which is located behind a control unit of the oven.

An oven appliance includes a cooking chamber for receipt of a food for cooking and an air exhaust channel having an air inlet and an air outlet. The air inlet is for directing air flowing adjacent to the cooking chamber into the air exhaust channel, whereas the air outlet is for directing the air out of the air exhaust channel. The oven appliance also includes a fan configured for causing air to flow from the cooking chamber and through the air exhaust channel. Further, the oven appliance includes a debris diverter component arranged with the air exhaust channel for preventing debris or liquid from contacting the fan.

The present invention relates to an electric oven capable of reducing contaminants, the electric oven comprising: an oven body having a cavity capable of accommodating food therein; and a convection assembly which is installed to protrude from one surface of the cavity and which can suck and remove contaminants generated when cooking the food and can heat the inside of the cavity. The convection assembly comprises: a cover case, protruding from one surface of the cavity, including a front surface which is spaced apart from the one surface of the cavity and has an inlet port, and a side surface which extends from the front surface to the one surface of the cavity and has an outlet port; a convection fan which is installed inside the cover case and allows air containing the contaminants to be sucked into the cover case through the inlet port and discharged through the outlet port; and a convection heater for heating the air sucked into the cover case by the convection fan to remove the contaminants, wherein the air discharged from the cover case moves in an upward inclined direction with respect to the one surface of the cavity.
