摘要:
A household cooking appliance, in particular an oven, comprises a cooking chamber defined by a muffle having a flue with a fume outlet at an upper wall of the muffle, and a front door, for opening and closing the cooking chamber. The appliance further comprises a delivery channel, defined by a duct body that extends above the upper wall of the muffle, the duct body having an outlet of the delivery channel that is substantially at a front region of the appliance, above an upper portion of the door, and having a fume inlet in a lower wall of the duct body, which is in fluid communication with the fume outlet of the muffle and with the delivery channel. Operatively associated to the duct body is a ventilation assembly, so as to draw in fumes from the fume outlet of the muffle and expel them from the outlet of the delivery channel, the ventilation assembly being in a rear end region of the duct body that is generally opposite to the outlet of the delivery channel. The ventilation assembly comprises a radial fan with a centrifugal impeller inside the duct body, the centrifugal impeller being positioned above the fume inlet of the duct body substantially coaxial thereto and to the fume outlet of the muffle in such a way that at least the fumes are drawn in from the fume outlet substantially in the direction of the axis (X) of the impeller and forced in a radial direction into the delivery channel for being expelled from the corresponding outlet. The rear end region of the duct body has a generally rounded peripheral profile so as to form a volute of the radial fan, the duct body preferably having a shape generally tapered towards its rear end region and comprising a lower half-shell and an upper half-shell. Provided inside the duct body, within the boundaries of the delivery channel, is a flow-deflector element configured for rendering the flow forced by the centrifugal impeller into the delivery channel uniform.

A gas oven configured to use a single cooking cavity (40) being divided into a plurality of individual cooking cavities (41, 42) by mounting a divider (43) at the cooking space. The gas oven includes a forced air supplying device (100) capable of forcedly supplying air to the individual cooking space at an upper portion of the cooking space, and a natural air discharging device (200) capable of naturally discharging waste air of the individual cooking space at a lower portion of the cooking space, when each individual cooking space is shut off by the divider.

A millivolt damper control device comprises a damper movable between a closed position where a flue is blocked and an open position, a thermoelectric device having an input voltage, a battery having a voltage, and a controller comprising a 7 comparator circuit which compares the input voltage with a reference voltage based 8 upon the voltage of the battery. When the input voltage is greater than or equal to 9 the reference voltage, the comparator circuit transmits a damper signal to move the damper to the open position.

Apparatus for exhausting the combustion gases of a stove with open combustion fired on liquid or gaseous fuel. A collector hood is mounted above the combustion gas outlet of the stove. A heat exchanger is connected to the collector hood. A fan exhausts the combustion gases through the heat exchanger to the exterior of the room to be heated.

The present invention discloses an open gas fire having a gas burner (1, 9), the combustion products of which are fed to a flue system (21) via a heat exchanger (15) for use in providing heated convection air. With such gas fire constructions too much cold air can be drawn into the fire through the front of the fire due to the capacity of the flue system. The flue system (21) has to be able to cope with the maximum quantity of combustion products which can be produced, to thus avoid spillage of the products from the front of the fire. At gas settings other than setting to produce the maximum combustion product, cold air is then drawn into the flue reducing the thermal efficiency of the fire. The present invention improves the thermal efficiency of the gas fire by providing an adjustable baffle (23) which is arranged to vary the flow-through cross-section of the path of the combustion products to the flue system (21). Thus the flue cross-section (21) can be matched to the combustion products quantity, reducing the quantity of cold air drawn into the front (3) of the fire and thus improving thermal efficiency.

Gargerät (1) umfassend einen beheizbaren Garraum (3) mit einer Beschickungsöffnung (4), eine Garraumtür (5) zum Verschließen der Beschickungsöffnung (4), eine Entlüftungseinrichtung (6) zur Abfuhr von Wrasen mit einer Entlüftungsöffnung (7) und eine Blendeneinrichtung (9). Die Blendeneinrichtung (9) ist zwischen einer Ruhestellung (10) und einer Betriebstellung (11) verlagerbar vorgesehen. Weiterhin deckt die Blendeneinrichtung (9) bei geschlossener Garraumtür (5) die Entlüftungsöffnung (7) in der Ruhestellung (10) im Wesentlichen ab und gibt diese in der Betriebstellung (11) wenigstens abschnittsweise frei. Bei dem Verfahren zur Durchführung eines Garprogramms mit einem solchen Gargerät (1) wird die Blendeneinrichtung (9) beim Betreiben des Gargeräts (1) wenigstens zeitweise während des Programmablaufs in die Betriebstellung (11) verlagert wird, um die Entlüftungsöffnung (7) wenigstens abschnittsweise freizugeben.
摘要:
A heating apparatus for cooking, which ventilates the insides of cooking chambers (11A,11B,111,112) after the cooking of food in the cooking chambers is completed, to rapidly cool the insides of the cooking chambers, and selectively ventilates (30,300) one out of the cooking chambers. The heating apparatus for cooking includes a main body (10,110) including a plurality of cooking chambers, which are separable from each other by a partition plate; a plurality of heaters (23A,23B,231,232) for respectively heating the cooking chambers; and a ventilating device (30,300) for ventilating the cooking chambers by introducing external air, wherein the ventilating device includes an air blowing unit (31,400) for blowing the external air to the insides of the cooking chambers, and a flow change unit (40,500) for selectively supplying air blown by the air blowing unit to one of the cooking chambers. In addition, methods to achieve the above are disclosed.
