Benefits of technology

The invention creates an air curtain over the stovetop to prevent cooking fumes from passing through. This helps to keep the fumes from polluting the air.

Problems solved by technology

Where the stovetop is placed in an open area such as an open-concept modern kitchen in a private home, or the eating area of an eatery for on-the-spot preparation of customer orders, for example as found in buffet spreads of luxury hotels or restaurants, installation of the extraction hood can pose particular challenges and difficulties from an engineering as well as an aesthetic standpoint.

first embodiment

[0028]In a first embodiment as shown in FIG. 1, the suction duct 20 comprises an L-shaped hollow tube preferably having a rectangular cross-section. The suction duct 20 is configured for placement above two adjacent edges 110, 120 of the stovetop 100, a side edge 110 and a back edge 120. Similarly, the supply duct 30 comprises a hollow tube preferably having a rectangular cross-section. The supply duct 30 is configured for placement above an edge 130 of the stovetop 100, such as the side edge 130 opposing the side edge 110 where the suction duct 20 is placed, as shown in FIG. 1. The suction duct 20 and supply duct 30 together form a simple U-shaped structure above and around the stovetop 100, providing a streamlined look while channelling cooking fumes 50 into the air cleaning device 60 to prevent the cooking fumes 50 from pervading the open space where the stovetop 100 is in use. Alternatively, the suction duct 20 may be configured for placement above only one edge 110 of the stove...

second embodiment

[0029]In a second embodiment as shown in FIG. 2, the suction duct 20 and the supply duct 30 comprise hollow walls extending upwardly from the edges 110, 120130 of the stovetop 100. The supply duct 30 is preferably adjacent the side edge 130 of the stovetop while the suction duct 20 is L-shaped and adjacent the side and back edges 110, 120 of the stovetop 100. Alternatively, the suction duct 20 may be adjacent only the side edge 110 of the stovetop 100. The suction duct 20 preferably comprises a plurality of the inlets 22 in the form of substantially horizontally disposed slots located at different heights on the hollow walls of the suction duct 20, although in other embodiments only one inlet 22 may be provided.

third embodiment

[0030]In a third embodiment as shown in FIG. 3, the supply duct 30 is configured for placement above and extending over the stovetop 100 between two suction ducts 20 provided on either side 110, 130 of the stovetop. The supply duct 30 is preferably placed centrally between the two suction ducts 20 and comprises a hollow tube having a rectangular cross section. The supply duct 30 is provided with at least one outlet 32 on each of two opposing lateral sides of the hollow tube such that each outlet 32 is directed towards each of the suction ducts 20.

[0031]As shown in FIG. 4, the apparatus 10 may comprise an upstanding rim 40 that curves inwardly towards the stovetop 100 provided on a top edge 28 of the supply duct 20 and a top edge 28 of the suction duct 30. The upstanding rim 40 is configured to help guide the air 24 containing the cooking fumes 50 towards the inlet 22 and also enhance the air curtain effect provided by the outflow of air 34.

[0032]Preferably, the apparatus 10 is confi...

Abstract

An apparatus for channelling cooking fumes arising from cooking taking place on a stovetop in a designated area, the apparatus comprising a suction duct having at least one inlet configured for intake of air containing the cooking fumes, the suction duct configured to channel the air containing the cooking fumes away from the designated area; and a supply duct having at least one outlet configured for outflow of air over at least a portion of the stovetop such that the cooking fumes are at least partially directed by the air towards the at least one inlet of the suction duct; the apparatus being hoodless.

Description

FIELD OF THE INVENTION[0001]The invention relates to an apparatus for channelling cooking fumes, and particularly, though not exclusively, relates to an apparatus for channelling cooking fumes arising from a stovetop placed in an open area.BACKGROUND[0002]Exhaust systems in kitchens typically comprise an extraction hood placed over a stovetop for capturing cooking fumes arising from cooking taking place on the stovetop. The cooking fumes are expelled to an exterior atmosphere via ducting provided between the hood and the exterior atmosphere. Where the stovetop is placed in an open area such as an open-concept modern kitchen in a private home, or the eating area of an eatery for on-the-spot preparation of customer orders, for example as found in buffet spreads of luxury hotels or restaurants, installation of the extraction hood can pose particular challenges and difficulties from an engineering as well as an aesthetic standpoint. Within the open area, which is notably lacking in wall...
