Definitions

  • This invention relates to a cooking appliance provided with an atmospheric burner, a thermal receiver, a chamber for distributing the gas/air mixture to the burner, and passages for the combustion products to enable their heat to be utilized for cooking, the combustion products passing through a space between the burner and the thermal receiver.
  • Cooking appliances structured in the aforesaid manner are known, for example from US-A-4,569,328.
  • the passages for the combustion products are holes passing through the said thermal receiver, with the negative consequence that any pan spillage, or spillage of the liquids used for cleaning the thermal receiver or dirt in general reach the burner, to harm its operation.
  • a heating (cooking) appliance is known from EP-B1-0520913 in which the air/gas mixture is fed centrally into a distribution chamber bounded upperly by the thermal receiver, lowerly by the burner and laterally by a metal ring surrounding the receiver and burner. In this appliance the combustion products do not pass through a space between the atmospheric burner and thermal receiver.
  • FR 2 082 312 A discloses an atmospheric burner to be placed in a tight chamber that is in communication with a chimney.
  • the specific object of the invention is to improve the heating (cooking) appliances of said US patent by eliminating the danger of deactivation of the burner and the fragility of the thermal receiver (due to the holes).
  • the reference numeral 1 indicates the appliance box casing, for example of sheet metal, provided preferably with a removable base 2.
  • This casing defines a compartment 1A and presents, in suitable positions not susceptible to occasional blockage (for example on the front and on the rear), wide apertures 3 communicating with the outside such as to enable operationally adequate quantities of combustion air to enter a conventional atmospheric burner 4, for example of channelized ceramic refractory either lined or not lined with a catalyst.
  • the atmospheric burner is preferably and advantageously of discoidal shape and is supported in, and closes, the upper aperture of a sheet metal cup member 5.
  • the atmospheric burner 4 is substantially and advantageously supported at the height of the upper surface 6 of the casing 1 (i.e. of the "cooking hob"). With the cup member 5, the burner 4 defines a chamber 7 for distributing the air/gas mixture which is fed to it via a conventional injector 8 fed with the gas, to draw air from the compartment 1A and hence produce the relative mixing.
  • the injector is connected at one end to the cup member 5 and at its other end to a conventional cock 9 for adjusting the gas flow rate (controlled by the knob 10) and connected to a gas feed conduit 11.
  • a preferably metal spacer means On the cooking hob 6, coaxial with the atmospheric burner 4, there is mounted a preferably metal spacer means, indicated overall by 12, of circular symmetry and provided with a preferably frusto-conical annular wall 12a.
  • This spacer means presents a base 12b for its resting on the cooking hob 6 and, on the opposite side, a ring 12c with a side wall 12d forming a support for the thermal receiver represented by a conventional discoidal glass-ceramic body.
  • the discoidal body 13 is supported spaced from the atmospheric burner 4 coaxially to it, and preferably and advantageously has a diameter greater than the base 12b of the spacer means 12.
  • the wall 12a comprises wide apertures 12e for the exit of combustion products from the space 14 lying between the glass-ceramic disc and the atmospheric burner 4.
  • the scope of protection of the present invention also includes the use of a cylindrical instead of frusto-conical shape for the wall 12a of the spacer 12, possibly inclining the axis of the apertures present in this wall.

  1. Appareil de cuisson, comprenant un brûleur atmosphérique (4), un récepteur thermique (13), une chambre (7) de distribution du mélange air-gaz au brûleur (4), et des passages pour les produits de combustion afin que leur chaleur puisse être utilisée pour la cuisson, les produits de combustion passant dans un espace (14) disposé entre le brûleur (4) et le récepteur thermique (13), dans lequel l'espace est délimité latéralement par une entretoise (12) qui, à une première extrémité, supporte le récepteur thermique (13) et qui, sur sa longueur, a des passages (12e) pour la sortie des produits de combustion de manière qu'ils quittent ces passages avec une composante de déplacement pratiquement perpendiculaire au brûleur (4) et au récepteur thermique (13).
  2. Appareil selon la revendication 1, caractérisé par un carter (1) en forme de boite ayant des ouvertures (3) destinées à communiquer avec l'atmosphère et qui sont disposées dans des faces du carter qui ne peuvent pas être interceptées au hasard.
  3. Appareil selon les revendications 1 et 2, dans lequel l'entretoise (12) est formée de métal et est en appui sur le carter (1) en forme de boíte.
  4. Appareil selon une ou plusieurs des revendications précédentes, dans lequel le brûleur (4) et le récepteur thermique (13) ont une forme de disque, le premier ayant un diamètre inférieur à celui du second.
  5. Appareil selon une ou plusieurs des revendications précédentes, dans lequel le brûleur (4) est disposé pratiquement au niveau de la surface supérieure (6) du carter (1) en forme de boíte.
  6. Appareil selon une ou plusieurs des revendications précédentes, dans lequel l'entretoise métallique (12) comporte une base annulaire (12b), une paroi tronconique (12e) comprenant les passages (12e) et, à sa partie supérieure, un anneau ayant une paroi latérale (12c + 12d) de support du récepteur thermique.
