Techniques regarding a fan friction oven are provided. For example, one or more embodiments described herein can regard an apparatus comprising a processing chamber in fluid communication with a heating blower and a circulation blower. The heating blower can heat air adjacent to the processing chamber by fan friction. Also, the circulation blower can circulate the air heated by the heating blower into the processing chamber.

A heat reclaimer mounted on an exhaust-conveying flue, the flue having a flue inside surface in contact with the exhaust, the heat reclaimer including a heat-exchange assembly adjacent to and in contact with the flue. The heat-exchange assembly includes: (a) a fan for moving ambient air; (b) a chamber through which the fan drives the ambient air, the chamber defining a primary airflow direction; and (c) a plurality of heat transfer plates inside the chamber and transverse to the primary airflow direction, the plates defining airflow openings therethrough and having at least an edge in solid-to-solid thermal contact with a flue inside surface portion inside the chamber, thereby heating the ambient air with heat from the exhaust.

A cooking appliance includes an exhaust inducing part creating at least one of a flow of air from a lateral surface of the housing to the other lateral surface of the housing and a flow of air to a rear surface of the housing from the front of the cooking space, while being disposed on the lateral surface of the housing.

A vent-free fireplace heat removal system and accessories for installation of components for same, and methods for removal utilizing same. The system includes components so that when in use, heat generated in the combustion space escapes into the room in which the fireplace is situated, and heat in the room within a determined distance from the fireplace enters a slot, collects in a collection duct, and passes through a heat exhaust aperture to be expelled from the room. In certain embodiments, a fan system enhances the ability of the vent-free fireplace to expel heat.

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.

An oven appliance includes a chamber, a fan assembly operable to cause air to flow in the chamber, and a first heating element adjacent to a bottom wall of the oven appliance. The oven appliance further includes a removable heating element cover configured for defining a duct in fluid communication with the fan assembly and the first heating element for directing airflow in the chamber to the fan assembly and across the first heating element to heat a food item. The oven appliance also includes a sensing device for detecting a presence of the heating element cover and a controller having a processor configured to receive an indication from the sensing device confirming whether the heating element cover is engaged with the sensing device and control operation of the oven appliance based on the indication.

A heating cooking device includes: a heating chamber having a front face opening; and a heater that is provided on an upper wall of the heating chamber to heat an object to be heated stored in the heating chamber, at least part of the heater being disposed at a center of the heating chamber seen from above. The heating cooking device further includes camera that is provided on the upper wall of the heating chamber and is disposed closer to a front of the heating chamber than the center of the heating chamber is when seen from above, with camera having an imaging direction inclined toward a rear side of the heating chamber with respect to a vertical direction. The heating cooking device further includes blower fan that is provided on the upper wall of the heating chamber, closer to a front of the heating chamber than the center of the heating chamber is when seen from above and is disposed at a position on one of a right side and a left side with respect to camera as seen from above, and that blows air toward camera from the one of the right side and the left side.

In one aspect, a cooking device includes independently controllable cooking zones. In one aspect, a cooking device includes a first cooking zone with heated air configured to move horizontally there through in a first direction and a second cooking zone with heated air configured to move horizontally there through in a second direction different than the first direction. In one aspect, the first and second directions are opposite directions. In one aspect, the heated air flows from one side of the cooking device.

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.
