Definitions

  • the present invention relates to the field of cooking appliances. electric type ovens appliances or any type of appliance used for cooking grills or roasting (grill, barbecue ...) and concerns more particularly a pivoting heating element and its arrangement in such a apparatus.
  • Document FR 2 720 917 discloses a heating element for an oven household appliances, mobile by means of a guide element allowing to move the heating element from a working position to a position release by pivoting around a loop. If this solution is good adapted to a position of the heating element at the bottom of the oven, it should, in a vaulted use of the heating element, provide a specific system for holding this heating element in position horizontal working.
  • the document FR 2 752 918 describes a pivoting furnace resistance, the mounting of said resistor being carried out using holes made in each of the side walls, the resistor being pivotally mounted around a tilt axis passing through said holes.
  • Each hole has a bearing fixed mounted, in which a portion of sheath of the corresponding free end of the resistor to allow pivoting resistance.
  • An elastic means makes it possible to recall the resistance in its working position, horizontal.
  • One of the objects of the present invention is to remedy the drawbacks of the prior art by providing a pivoting heating element for a electric cooking which is easy to carry out and implement, in order to reduce manufacturing costs, without degrading the functionality of the element heating, and while allowing simple handling of the heating element for the user.
  • an electric cooking appliance comprising a frame comprising at least one floor wall and / or a wall of vault, at least one side wall, defining a cooking enclosure, at at least one tubular heating element arranged in the cooking chamber, at near the roof and / or the floor of the electrical appliance, said element heater can be positioned, by rotation, on the one hand in a position horizontal working, and on the other hand in a position of release by relative to said working position, characterized in that said heating element has two end parts, the free ends of which are connected by connectors to an electrical circuit supplying the heating element, said end portions extending out of the cooking chamber by a opening made in one of the side walls and each comprising at minus a protrusion substantially adjacent to the side wall in order to limit the deflections by rotation and / or by translation of said element heating.
  • the protuberance produced on the extreme parts of the element heating is obtained by stamping the heating element under a press.
  • the stamping creates a flattening of the heating element, and therefore a transverse widening thereof, widening capable of retaining the element heating in its deflections.
  • the cooking appliance comprises a frame 3 and a heating element 10 of the type shielded.
  • the different parts of the frame 3, shown in Figure 1, are consisting of a vault 5 secured with side walls 4 and / or a rear wall 7, thus delimiting a cooking enclosure 2.
  • An access door, not shown, makes it possible to produce a closed cooking chamber of an oven electric 1.
  • the heating element 10 extends in an extension plane substantially horizontal, in the vicinity of the roof 5 when said heating element 10 is in a working position, where the electrical device is powered to proceed to a cooking.
  • one of the side walls 4 of the oven has two openings 8 by which the heating element 10 passes through said side wall 4, as as illustrated in Figure 2.
  • This side wall can be completed by a cross 6 to stiffen the entire oven.
  • the heating element 10 is arranged in zigzag in order to best distribute the radiated power.
  • the parts of the heating element located outside the cooking chamber are designated by the reference 11 and called extreme parts.
  • part extreme so here is meant a portion of the heating element 10 comprising the very end of this element and a portion of the heating element extending from the end of the heating element to the side wall 4, the length of this extreme part being able to go up to approximately 10% of the total length of the heating element.
  • These two end parts of the heating element are located on the same side from one of the two side walls and at substantially the same height in the oven.
  • connection electric heating element via connection lugs 12 mounted on crimping rings 14 and connected to the electrical circuit (not shown) supplying the heating element.
  • end portions 11 are arranged return means elastic 16 of the heating element 10 to allow it to occupy a horizontal working position, while offering the possibility, by soliciting the elastic means 16, to pivot the heating element 10 in order to clean the vault or floor adjoining the heating element 10.
  • the heating element 10 is pivoted around the fulcrum 9 of the heating element 10 on the side wall 4 of the cooking appliance, at the level of the opening 8.
  • the return means which can be a spring as in the example presented or any other similar means, comprises, at its end, a fastener 18.
  • This fastener can have various shapes, such as a hook, a necklace, or a loop as presented in the proposed example, allowing to surround partially or totally the tubular heating element 10, on the part extreme and according to a section of it.
  • the end part of the heating element 10 has a projection 20 intended to retain the return means 16 during operation of the device.
  • This outgrowth can be obtained in different ways, either by adding of an element locally surrounding the heating element, either by deformation of the heating element to the extent that its constitution allows.
  • the projection of the extreme part 11 of the element tubular heater is obtained by stamping causing a flattening of the heating element with consequent widening, transverse to the matrixing, as it is clearly visible in FIGS. 3a and 3b.
  • the core 22 of the heating element 10 is also shown in these figures.
  • This element is preferably of the shielded type, that is to say made up of a tube containing a coiled resistive wire surrounded by magnesia.
  • the loop 18 of the return means cannot slide towards the connector 12 and can only slide between the projection 20 of the heating element and the wall side 4 of the cooking appliance. There is indeed no need to establish a fixed mechanical connection between these two elements, the recall function being able to be carried out with a fairly large latitude on the lever arm used.
  • the end portions 11 of the heating element 10 can be tilted towards the return means so that the latter is localized, by systematic sliding, against the outgrowth of the element heating.
  • the return means 16 exerts its force in the same place, producing identical torque during successive manipulations of the element heated by the user. This feature ensures a reproducible and systematic positioning of the heating element in its working position and ensures the horizontality of said heating element.
  • Another advantage to a bent arrangement of the end parts is to prevent the heating element 10 from sliding through the openings 8 when this heating element only consists of a single loop.
  • the heating element can therefore be moved or pivoted to a releasing position the floor and / or the vault to facilitate its cleaning, the pivoting angle being able reach 90 °.
  • the present invention can also be applied to a heating element located near the roof of the electrical appliance or located near the floor of said device, the possible reversal of the elastic return means 16 allowing to adapt the assembly according to the position of the heating element.
  • Another object of the invention relates to guiding and holding the element heater 10. Indeed, the freedom given to the heater to be able to pivot in order to free himself from his working position must however be limited in its lateral deflections, either in translation between the two lateral walls, by sliding in the opening 8 along the arrow G in Figure 4, or rotation perpendicular to the authorized rotation, i.e. in a movement between the rear wall of the oven and the front door, according to arrow F, figure 4.
  • a protuberance may be provided on the end portions 11 obtained similarly to the protuberance 20, that is to say by adding material or by deformation, and located substantially adjacent to the side wall 4, thus avoiding lateral movements of the heating element 10 which could cause dangerous contacts between connectors 12 and the frame the device.
  • this principle of guiding and restricting travel can be applied to any pivoting resistor, regardless of the presence or not a reminder, so regardless of the problem of keeping the loop for maintaining the return means, and / or for locating the element heating in the oven enclosure, in the top or bottom position.
  • the heating element when it is in the sole position, it may not be provided with a reminder, gravity being responsible for recalling the element heating in a horizontal position when it has been released from its working position.
  • a protrusion such as the appropriately positioned protrusion 20, then avoids the deflection of the heating element.
  • the projection 30 produced on the end portions 11 of the heating element 10, close to the wall 4.
  • the projection 30 can be obtained either by adding an element locally surrounding the element heating, either by deformation of the heating element, in particular by stamping.
  • this lateral holding function of the heating element 10 can be combined with that of guiding or holding the loop 18 of the return means 16, by a judicious length of the end portions 11 of the heating element 10 so that the projection 30 is located substantially against the side wall 4.
  • FIG. 4 illustrates this advantageous embodiment where the holding loop 18 of the return means 16 is located between the protrusions 20 and 30.
  • the loop 18 cannot slide on the part extreme 11 only between the two growths 20 and 30 which can be close enough to each other to maintain, without play along the heating element, the holding loop 18, the protrusion 30 avoiding also the transverse deflections of the heating element.
  • a means for retaining the element heating when the latter is positioned, by lateral pivoting, out of its working position can be simple hooks or metal clip elements or any other similar device. The cleaning of the vault and / or the sole is then facilitated, the user not having to hold the heating element in the retracted position to proceed with the cleaning.
  • the electric cooking appliance according to the present invention constitutes preferably an oven, grill or barbecue.
