Definitions

  • the present invention relates to a gas burner for a working table of a cooking appliance, in particular of a domestic cooker, which allows both normal cooking at high or medium temperature, cooking at low temperature for example the simmering necessary for the preparation of certain sauces which require low temperatures of the order of 50 to 90 ° C with a very slight temperature gradient on the bottom of the container containing the food to be prepared.
  • the present invention overcomes such drawbacks.
  • the present invention consists in providing a very flexible burner, at its upper part with a cup providing a passage of heat-carrying blown air between the latter and the diffuser cap, which allows reduced flow to reduce the container bottom temperature up to 50 ° C, temperature below which it is no longer possible to cook, while further reducing the temperature gradient on the surface of the container to a value below 10 ° C.
  • the invention therefore relates to a gas burner suitable in particular for low-temperature cooking of the order of 50 to 90 ° substantially, of the type mainly comprising a gas injector disposed in front of a horizontal venturi, a cup pierced with orifices of combustion and pilot orifices, characterized in that it further comprises a pipe comprising on the one hand a horizontal part surrounding said venturi and on the other hand a vertical part comprising two circuits, an external circuit communicating with said venturi and supplying a combustible gas mixture, said main and pilot orifices, and an internal circuit communicating on the one hand with means capable of ensuring a circulation with variable flow of fresh air in a space delimited by said cup and a diffusing cap disposed above said cup.
  • a burner according to the invention comprises a gas injector 1 disposed in front of a horizontal venturi 2 mounted to slide by means of a seal 3 in the horizontal part of a pipe 4 which is a piece of molding.
  • the vertical part of the pipe 4 has two circuits. First an external circuit 5 which supplies a combustible gas mixture to the main orifices 6 and the pilot orifices 7 of the burner cup 8 and secondly an internal circuit 12 connected to a device for blowing fresh air which will be described with reference to Figures 2 to 5.
  • the cup 8 comes to bear on the flat part 32 of the head 9 which covers the passage opening 10 of the burner in the hearth plate 11 of the cooking appliance.
  • This head 9 comes to bear on an outer rim 34 of the pipe 4, located in the same plane as the flat part 31.
  • the burner further includes a diffuser cap, two variant embodiments of which are illustrated in FIG. 1.
  • a diffuser cap two variant embodiments of which are illustrated in FIG. 1.
  • the diffuser cap 35A On the left part of the axis AB, it can be seen that the diffuser cap 35A, the end of which is arranged opposite that of the cup 8 comprises an axial duct 36 the walls of which come to bear on the upper part of the hub 30. Holes (not shown) put this duct 36 in communication with the space delimited by the diffuser cap 35 A and the cup 8.
  • the shape of the diffusing cap is different and it comes to bear by means of pins such as 40 on the cup 8.
  • Such an assembly can be fixed to a support plate 17 of the cooker by means of screws such as 18.
  • the injector 1 and its supply tube 20 can be screwed onto a support 19 itself fixed to the sheet metal 17 (FIG. 1).
  • the elbow 15 has an opening 24 communicating with the atmosphere, the useful air flow rate being adjustable by means of a shutter 25 capable of pivoting about an axis 26 and the control of which can be ensured remotely.
  • a shutter 25 capable of pivoting about an axis 26 and the control of which can be ensured remotely.
  • a flexible or angular return system of any known type, operated by a lever similar to those actuating the burner valve. In its extreme positions, this shutter completely closes either the opening 24 or the passage of air in the circuit 12.
  • FIG. 1 shows the grid 22 of the stove supporting a pan 23 for example.
  • the fan should only operate in low temperature cooking mode.
  • its supply circuit includes a switch, the closure of which is ensured by a cam integral with the turning of the valve, and cutting this circuit as soon as its position corresponds to a higher gas flow no longer suitable for simmering at low temperature, so as to keep the burner at full capacity for ordinary cooking.
  • the diameter of the diffuser cap 35A or 35B is limited by the need to allow the flames, at nominal flow rate, to directly reach the bottom of the pan 23.
  • Another possibility consists in modulating by all or nothing the electrical supply of the fan according to a variable cycle at will using a known device such as a rotary switch, a mobile or electronic bimetal energy regulator which realize thus a sequential operation of the fan.
  • This adjustment can of course be made by varying the speed of the motor actuating the fan.
  • the reference 4 designates the burner pipe, the vertical part of which has an internal circuit 12 as previously described, connected to a device for blowing fresh air by fan according to another embodiment.
  • the device according to this embodiment comprises a circular disc 127 placed between a housing 128 (replacing the elbow 15 of FIG. 2) and the outlet of the fan 113 whose positioning has been modified to allow the removal of the tube 14 of this same figure 2, and thereby a more compact construction.
  • the housing 128 is completely closed except for its air inlet orifice 129 and the opening 30 allowing the passage of the vertical lower end of the pipe 4.
  • the disc 127 is provided with a pin 131 passing through the front wall 132 of the cooking appliance as well as the control panel 133 and receiving at its end the control lever 134.
  • the disc 127 obscures the air outlet orifice 135 of the fan 113 except when the cutout 136 visible in the front view in FIG. 4 is opposite it.
  • Figure 5 is a variant of Figure 4, according to which the cutout 136 of Figure 4 has been replaced by several juxtaposed cutouts 137 separated by bridges of material and ensuring better rigidity of the disc 127 without disturbing the passage of the air, which is shown in Figure 3 by arrows.
