Definitions

  • the present invention relates to a ventilation system for a table or similar cooking appliance, comprising in particular an upper plate of reinforced glass or of a transparent ceramic material, heating zones distributed under the plate and a box in which these zones are mounted. and their electrical power supply and operating control members, this box being fixed under the plate and forming with it a one-piece assembly, of relatively reduced thickness and whose generally square or rectangular outline allows it to be embedded in a suitable housing at the top of a piece of furniture or similar support element, which fits into the layout of a domestic or other kitchen.
  • a fan is conventionally used (see FR-A-2 417 725), of the centrifugal type or of the so-called tangential type, the thickness dimensions of which can be reduced enough to allow it to be housed in the mounted box. under the plate inside the table.
  • the fan must have an air intake and a discharge section of sufficient size.
  • the suction is carried out directly in the cabinet, which requires practicing in the latter suitable openings with cutouts of the floor, the bottom and if necessary the drawer or the door of this furniture, surrounding the housing of the box, the discharge generally takes place in the rear part of the box, opposite its front face visible from the outside.
  • the present invention relates to a ventilation system for a hob which avoids these drawbacks, this table with its ceramic glass upper plate and its lower casing forming an autonomous assembly, capable of being cooled in operation without requiring any air intake to be produced. in the cabinet where it fits.
  • the system considered, for a hob having a glass plate or the like at its upper part, a lower flat box, integral with the plate and placed under it, this box housing one and preferably several hearths of heating mounted inside the box and of the electrical and electronic organs for controlling and regulating these fireplaces, as well as a cooling fan, is characterized in that the glass plate is supported by a peripheral angle of the box, this angle resting by means of a horizontal bearing surface on a piece of furniture receiving the table in a recess space of corresponding dimensions and having a substantially vertical rim provided with a lateral extension to which the plate is applied inside the angle iron, this rim being provided with passages respectively for the entry of ambient air sucked in by the fan and for the exit of this air after discharge inside the box, these passages being preferably arranged in opposite sides of the angle iron.
  • the air inlet passages formed in the edge of the angle iron are provided towards the front of the box and the outlet passages towards the rear of the latter.
  • these passages can be provided on the lateral sides of the angle iron.
  • the peripheral angle surrounding the glass plate is hollow and has a slightly rounded outward return whose end is in contact with the horizontal bearing surface of the table.
  • the box has a bottom bottom formed of a flat sheet or has a double bottom delimited by two parallel sheets providing between them a space for circulation of the air discharged by the fan.
  • the fan is housed inside the box near the side of the box having the air inlet orifices.
  • the reference 1 designates a hob consisting of an upper plate 2, made of reinforced glass or of a vitroceramic material and of a lower box 3, placed under the plate 2 and containing in particular heating zones (not shown), suitably distributed under the plate, these fireplaces may include, as the case may be, electric resistances, halogen lamps delivering infrared radiation or even magnetic coils to produce induction heating by coupling with metal utensils placed on top of plate 2.
  • the table 1 is designed to be embedded inside a support unit 4 having a housing 5 of suitable dimensions in which the table 1 and in particular the box 3 is placed, placed under the glass plate 2.
  • the table 1 rests on a horizontal bearing surface 6 of the cabinet 4 by means of a metal angle iron 7 comprising a lateral extension 8 to which the external peripheral edge of the plate 2 is applied, this extension comprising a substantially vertical rim 9 surrounding at its periphery the glass plate.
  • the flange 9 extending from the extension 8 supporting the plate 2 may have an end 10 closed on itself, as shown in Figure 1, or extend by a return 11 extending towards the exterior as illustrated in FIG. 2, this return having in this case a rounded profile terminated by a folded end 12 coming into contact or in the immediate vicinity of the bearing surface 6.
  • the angle iron 7 comprises a plurality of passages such as 13 and 14 formed in its vertical edge 9, making it possible to communicate through these outside the table 1 and the inside of the cabinet 4 in the housing 5 where s' embed the table, the passages 13 being for example reserved for a suction of ambient air inside the angle iron 7, while the passages 14 allow the simultaneous evacuation of the air thus sucked.
  • the angle iron 7 comprises a bottom plate 15 with a vertical return 16 engaging in the housing 5, in particular in the clearance 17 formed between the corresponding edge of the table 4 and the sides of the box 3, in order to ensure positioning and adequate centering of the table 1 when it is embedded in this housing.
  • the box 3 provided under the glass plate 2 contains, under the plate 2 a fan 18, the detail of which does not directly contribute to the invention, this fan being able to be especially of the centrifugal or tangential type, the only imperative to be satisfied being that it can be housed at the inside of the box without interfering with the installation in it of the heating zones providing the heat necessary for cooking through the plate 2.
  • FIG. 3 there has also been shown diagrammatically, with reference 19, an electronic circuit for controlling the heating foci of the table 1 and for regulating the temperature delivered by these foci according to the various heating stages chosen by the user.
  • the problem to be solved is essentially to ensure satisfactory cooling of the circuit 19 and in particular of the electronic components of this circuit by means of the fan 18, without the need to spare in the cabinet 4, in particular in the bottom or the sides thereof, openings for the suction and discharge of the air driven by the fan 18.
  • the air thus sucked in is discharged at high speed by the turbine inside the box 3 and in particular on the electronic circuit 19 which it cools vigorously before to be forced out of the box at the opposite end of it by the passages 14.
  • the mounting is slightly different, the box 3 having a double bottom delimited by the sheet 21 and a parallel sheet 25 located under the first, delimiting between them a circulation space 26. Ports 27 are provided at the ends of this circulation space so that the air sucked into the clearance 17 through the passages 13 precedes it, is then taken up by the turbine 23 passing through the communication orifice 24 of the sheet 21, then driven back by it both inside the box to cool the electronic circuit here not shown and in space 26 to keep the bottom of the box and the part facing the cabinet 4 at a satisfactory low temperature.
  • the inlet and outlet passages 13 and 14 of the air sucked in and then discharged by the fan 18 may be in the form of holes made in the vertical flange 9 of the angle iron, as illustrated in FIG. 2, or well fit the shape of more or less elongated slits.
  • the inlet orifices are provided on one of the lateral sides or on the front face of the angle iron 7, the outlet orifices being arranged on the opposite side or the rear face; however, any other development could be considered.
  • the invention in no way prejudges the embedding depth of the hob, provided that this allows the housing of the box and, in the latter of the fan, the latter being able, moreover, as already indicated, be of the centrifugal, tangential or helical type.
  • the proposed solution allows a safe installation of the table without specific constraints and without in particular requiring interventions on the piece of furniture which receives it, the dimensions of which can thus be particularly well adjusted.
