Definitions

  • the invention relates to household electric ovens comprising a cooking enclosure which opens on its front face and which contains a heating element for the vault and at least one heating element for the bottom, a switch capable of occupying either a position "of oven operation "for which at least the hearth resistance is supplied, that is to say a" grill operation "position for which only the vault resistance is supplied, and a door arranged on said front face and adapted to take, in particular, either a closed or "operating in the oven” position for which it is applied against the surround of the front opening, or a half-open or “operating in the grill” position for which it leaves on this opening a circulation space for air between the enclosure and the exterior.
  • the invention relates more specifically to household ovens of this kind which further comprise movement transmission members arranged between the resistance control switch and the door and intended to obtain an automatic correlation between the position of the door and the operation of the switch.
  • US patent - A - 4189632 describes a furnace of this kind in which the door, which is normally closed during the operation in grill, opens automatically at the end of this operation in grill and controls the simultaneous stop of the resistor supply.
  • the door which is normally closed during the operation in grill
  • the vault resistance being of generally high power, causes an abnormal rise in temperature in the cooking chamber, risking damage to the constituent parts of this oven, and destroying the thermostat fitted to the appliance.
  • the object of the invention is to provide an improvement to this kind of oven so as to allow operation in the grill position only with the door in the ajar position, in order to eliminate the drawbacks described above.
  • the movement transmission members comprise a crank mounted movable on the surround of the front opening and mechanically linked to the control of the switch so that, when the switch is in its operating position in an oven, the spreader is in a rest position for which it is retracted and thus lets the door come into its closed position, and that, when the switch switches to its operating position on the grill, the spreader switches to an active position for which it is interposed between the door and said surround to bring and maintain this door in its ajar position.
  • the oven is transformed into a grill and this automatically, without the user having to worry himself about placing the door in the half-open position, the ajar opening aside the entourage door as soon as the user switches the switch from its operating position in the oven to its operating position in the grill.
  • the oven shown comprises a cooking chamber 12 which opens on its front face and which contains a heating resistance of the roof 14 and two heating elements of the bottom 16 and 18. These resistances are controlled by a switch 20 (FIGS. 3 to 5) which is likely to occupy either an operating position in the oven ( Figure 4 and position A in Figure 3) or an operating position in the grill ( Figure 5 and position B in Figure 3).
  • a switch 20 FIGGS. 3 to 5
  • the resistor 16, on the one hand, and all of the resistors 14 and 18 in series, on the other hand are supplied in parallel on the mains voltage applied to the input terminals 22 and 24.
  • For the grill operating position only the top heater 14 is supplied.
  • the supply voltage is applied to the resistors through a thermostatic switch 26 (only a small part of which is shown in FIGS. 4 and 5) intended to regulating the temperature of the cooking chamber during operation in the oven.
  • the cooking chamber 12 is equipped with a door 28 arranged on the front face and articulated around a horizontal axis 30 located in the vicinity of its lower edge.
  • This door can take, in particular, either a closed position ( Figures 2 and 4) for which it is applied against the surround 32 of the front opening, or a half-open position ( Figures 1 and 5) for which it leaves on this opening an air circulation space 34 between the enclosure 12 and the outside.
  • the resistance control switch 20 is actuated by a movable key 36.
  • This key is itself operated by a rotary shaft 38 which is itself coupled to the adjustment shaft 40 of the thermostatic switch 26.
  • the shaft 38 is provided with a manipulation button 42 and carries a lateral projection 44 which, for a determined angular position of this shaft (fig.5), comes to operate the key 36 of the switch 20 to bring this switch to its position grill operation (position B in Figure 3).
  • This position corresponds to an angular position of the button 42 identified by the letter G, as can be seen in FIG. 5, on which a partial cutout of the shaft 38 has been carried out in order to clearly show the projection 44.
  • the adjustment shaft 40 ensures, for this position, a blocking of the thermostatic switch 26 in a permanently closed position of this switch.
  • the projection 44 releases the key 36 and thus leaves the switch 20 in its operating position in the oven (position A in FIG. 3), the thermostatic switch. 26 being itself also released to ensure temperature regulation as a function of the chosen setting: this choice is made by turning the button 42 to place it in correspondence with one or the other of numerical marks (for example 10 or 9, as in Figures 4 and 5).
  • Motion transmission members arranged between the switch 20 and the door 28, are adapted to ensure that the passage of this switch from its operating position in the oven to its operating position in the grill automatically causes the passage of the door 28 from its closed position ( Figure 4) to its half-open position ( Figure 5).
  • These motion transmission members comprise a stay 46 mounted movably on the surround 32 of the front opening and mechanically linked to the control shaft 38 of the switch 20 so that, when this switch is in its operating position in the oven (FIG. 4), the stay 46 is in a rest position, for which it is retracted to let the door 28 come to its closed position, and that, when this switch switches to its operating position in the grill (FIG. 5), the ajar 46 goes into an active position for which it is interposed between the surround 32 and the lateral edge 48 of the door 28 to cause this door to pivot outwards to its ajar position and to hold it there.
  • the ajar 46 is constituted by a sliding rack whose teeth 50 are engaged with a toothed wheel 52 secured to the rotary shaft 38 and whose pointed free end carries a ramp inclined 54 adapted to engage between the edge 48 of the door 28 and the surround 32 when the rack moves into its active position.
  • the transmission members arranged between the switch 20 and the door 28, and constituted by the shaft 38, the toothed wheel 52, the rack 46, and the ramp 54, are adapted to ensure, not only that the passage of the switch 20 in its grill operating position causes the door to pass into its ajar position, but again, conversely, that the return of the door to its closed position causes the switch 20 to pass into its operating position in the oven.
  • the user therefore does not have to worry about placing the door 28 in a position suitable for grill operation, since this operation is done automatically. He also does not have to worry about manipulating the button 42 when he wishes to return to the operating position in the oven, since this operation is also carried out automatically.
