Definitions

  • the present invention relates to a household gas cooktop.
  • a gas cooktop is known to comprise a supporting and containing structure having an upper wall with an upwardly faced on-sight surface, a support grid arranged on the on-sight surface which defines a plane to support containers to be heated, e.g. pots, and one or more fuel gas burners so configured as to generate a series of flames in the gap between the on-sight surface and the support plane, in order to heat the containers supported by the support grid.
  • Known burners for gas cooktops usually comprise a main gas supply duct connectable to an external fuel gas source, for example to the gas pipe network or a gas cylinder.
  • One or more combustion units are connected to the main duct through one or more gas partial ducts, respectively.
  • a regulating valve (usually called the gas tap) is associated to each of the gas partial ducts, which is so configured as to regulate the gas passage through the partial duct between a closed position and a maximum opened position.
  • a safety valve is provided to cut the gas passage off through the partial duct in response to a signal indicative of an incorrect operation of the combustion unit.
  • Such safety valve can be arranged upstream or downstream the regulating valve (in relation to the gas flow direction from the main duct to the combustion unit), or integrated in the valve body of the regulating valve.
  • the burner is a non-aerated burner, or an atmospheric air burner (called induced air burner), in which a venturi tube mixer is provided which is arranged in the partial duct upstream the combustion unit and adapted to suck a primary air amount in the gas partial flux.
  • a further volume of secondary air is needed for an efficient combustion, which is drawn by the same flames in the gap between the support plane (pot bottom) and the upper wall on-sight surface.
  • JP 02 089917 A discloses an example of a prior art cook top having features of the preamble of claim 1.
  • object of the present invention is to provide a household gas cooktop having such characteristics as to obviate at least some of the drawbacks cited with reference to the prior art.
  • a further object of the present invention is to propose a household gas cooktop which allows a drastic reduction of CO and CO 2 emissions during operation.
  • a still further object of the present invention is to propose a household gas cooktop which allows reducing the distance between the support plane (pot bottom) and the on-sight surface, in order to permit innovative design solutions.
  • a household gas cooktop is generally indicated with the reference numeral 1.
  • the cooktop 1 comprises a supporting and containing structure 2 with an upper wall 3 which has an on-sight surface 4.
  • one or more support members 5 are arranged which support the containers to be heated, for example pots, pans, coffee makers, etc., and define a support plane 6 thereof on the side of the on-sight surface 4 of the upper wall 3.
  • One or more combustion units 7 are arranged at the upper wall 3, preferably partially projecting and partially inserted in such upper wall.
  • the combustion units 7 are so configured as to generate flames in a space 8 between the on-sight surface 4 and the support plane 6 which, in use, matches to the pot bottom plane.
  • the gas cooktop 1 further comprises a gas supply system 30 supported by the supporting and containing structure 2 and so configured as to be able to supply a gas flow 34 to the combustion unit 7.
  • the gas cooktop further comprises a forced suction group, for example an electrical blower 9 adapted to suck a secondary air volume 10 through a suction opening obtained in the supporting and containing structure 2 and to convey such secondary air 10 in a ventilation duct 11 which extends in the support structure 2 (at least partially, preferably completely) beneath the on-sight surface 4.
  • a forced suction group for example an electrical blower 9 adapted to suck a secondary air volume 10 through a suction opening obtained in the supporting and containing structure 2 and to convey such secondary air 10 in a ventilation duct 11 which extends in the support structure 2 (at least partially, preferably completely) beneath the on-sight surface 4.
  • the ventilation duct 11 preferably extends on a lower side 12 of the upper wall 3 opposite the on-sight surface 4.
  • the ventilation duct 11 connects the electric fan 9 to the combustion unit 7, so as to be able to supply the secondary air volume 10 to the latter.
  • the support members 5 are formed integrally with the upper wall 3, which is manufactured by means of cast iron fusion.
  • part of the combustion units 7 is also formed integrally with the upper wall 3.
  • the combustion units 7 comprise a diffuser 13, which defines a plurality of gas outlet holes 14, and a base portion 15, which forms one or more distribution chambers 16, 17 adapted to spread and convoy the gas flow 34 and the secondary air flow 10 to the diffuser 13.
  • the base portion 15, 16, 17 is formed integrally with the upper wall 3.
  • the whole upper wall 3, the support members 5, and the base portions 15 of the combustion units 7 are formed by means of cast iron fusion in a single piece. Beside the plain advantages in the cooktop assembling, such integration of upper wall, support members, and burner cups in a single cast iron piece markedly decreases the production cost of the whole appliance.
  • the upper wall 3 and the diffuser 13 are shaped in such manner that a transition zone 19 between the on-sight surface 4 and an outer surface 18 of the diffuser 13 has an essentially continuous, without step progression, in order to promote the gas cooktop cleaning.
  • this transition zone 19 can have a surface interruption, or a grout line or slit between the upper wall 3 and the diffuser 13 which are preferably manufactured individually and in different materials.
  • the ventilation duct 11 is connected to a plurality of combustion units 7 and comprises a ventilation chamber 20 essentially plate-like and extending on all the combustion units 7 which it supplies with secondary air 10.
  • the ventilation chamber 20 has a distribution wall 21 which defines a plurality of air outlet openings 22, each connected to a combustion unit 7.
  • the base portions 15 of the combustion units 7 form a secondary air distribution chamber 17 and a gas distribution chamber 16, as well as a tubular portion 25 in flow connection with the secondary air distribution chambers 17 and vertically downwardly projecting.
  • the distribution wall 21 is arranged on the lower side 12 of the upper wall 3 and shaped so as that the tubular portion 25 is inserted in the relative air outlet opening 22 or, alternatively, on an edge of such air outlet opening 22.
  • sealing gaskets can be provided between the air outlet openings 22 and the relative tubular portions 25.
  • the supporting and containing structure 2 further comprises a lower wall 26 with upwardly bent outer sides and connected, for example, glued, to the upper wall 3.
  • the distribution wall 21 comprises, in turn, downwardly bent outer sides and connected to the lower wall or abutting against the latter, so that the lower wall 26 and the distribution wall 21 define the ventilation chamber 20.
  • a sealing gasket for example a rubber tape, is provided in the junction area between the distribution wall 21 and the lower wall 26.
  • the blower 9 is located in a seat 27 formed by the lower wall 26 and the upper wall 3 or the air distribution wall 21, and a blower 9 suction opening is connected to a gas cooktop suction grid, while the blower outlet opening is in flow connection with the above-mentioned ventilation duct 11, particularly with the ventilation chamber 20.
  • the ventilation chamber 20 which extends in the supporting and containing structure 2 plane forms a first portion 28 without said air outlet openings 22, and one or more second portions 29 with the air outlet openings 22, in which the second portions 29 have a height which is lesser than the first portion 28 height, so as to promote an even distribution of the secondary air on all the outlet openings 22.
  • the gas supply system 30 of the cooktop 1 comprises a main gas supply duct 31 which can be connected to an external fuel gas source.
  • One or more partial ducts 32 connect the main duct 31 to each of the combustion units 7, and a regulating valve 33 associated to the partial duct 32 allows a regulation, preferably continuous, of the gas passage through the partial duct 32 between a closed position and a maximum opened position.
  • Air adduction means can be provided in the partial duct 32 which are configured so that, during operation, the gas flow 34 in the partial duct and/or the same flame draw a first volume of oxidizing primary air.
  • the air adduction means comprise, for example, a venture tube device (not shown) with a gas passage having a throttled section portion and one or more primary air passages which open in the proximity of the throttled section portion, so that the gas acts as a driving fluid in order to draw the primary air volume in the partial gas flow 34.
  • the forced suction group 9 is advantageously configured so as to suck the secondary air 10 from a zone which is different from the zone of the primary air volume.
  • a control unit 35 drives the forced suction group 9 in response to an actuation of the regulating valve 33, so as to actuate the forced flow of secondary air concurrently to a gas supply to the combustion unit 7.
  • the household gas cooktop 1 has a number of advantages. Due to the provision of a ventilation duct 11 arranged on the lower side 12 of the upper wall 3 opposite the on-sight surface 4, the cooktop visible parts, in particular the space between the on-sight surface 4 and the support plane for the pots, can be formed in an aesthetically very pleasant design, without compromising the most complete combustion possible. Furthermore, while keeping the heating power constant, the CO and CO 2 emissions turn out to be sensibly reduced compared to those of the gas cooktops of the prior art.
  • the manufacturing of the upper wall and the support members in a single piece by means of cast iron fusion reduces the production and assembling cost and time for the cooktop.
