Definitions

  • the invention relates to a cooking plate intended to equip a cooking appliance such as a hob having at least one burner gas.
  • the cooking plate is made of glass-ceramic or in another material resistant to high temperature and having a low coefficient of expansion.
  • Such gas burners are usually arranged in a usually metal structure called "caisson" and covered by a vitroceramic plate equipped with a frame that closes the structure.
  • DE-U 298 05 620 discloses such a cooking appliance and more particularly mounting means for fixing the gas burners to the ceramic hob with joints to make the connection between the ceramic hob and gas burner.
  • WO97 / 00407 still describes such a cooking appliance in which gas burners are surrounded by elements to support utensils of cooking used for cooking food.
  • FR-B-2,735,562 discloses cooking appliances having a ceramic hob providing support for gas burners and allowing also to ensure the support function of the cooking utensils.
  • the inventors have set themselves the task of offering the possibility of provide a cooking appliance having at least one gas burner and whose upper part is formed of a hob, such as a plate vitroceramic, for which the cleaning is made even simpler than this that do not allow currently known products.
  • a cooking plate such as a ceramic hob, intended to equip a cooking appliance comprising at least one gas burner, said glass-ceramic plate comprising a zone intended to cover the gas burner and said zone comprising lateral part of the orifices, provided in particular for forming an air intake towards the gas burner and to allow the exit of the flames.
  • the gas burner is completely masked by the plate of cooking and therefore invisible to the user; such a simplified design doubling the cleaning of the cooking appliance. Indeed, first of all, the gas burner that is masked is protected from soiling and therefore less subject to fouling. In addition, when the user cleans the apparent part of the cooking appliance, it must simply perform the cleaning of the plate of cooking, which significantly simplifies the operation compared to the cleaning of cooking appliances currently available.
  • the cooking appliance comprising a gas burner only allows the appearance of ports which are, as said before, provided on the one hand to allow an air supply to the burner and secondly, to allow the formation and the flames exit at the top surface of the hob so as to come to heat the cooking utensils.
  • the orifices are holes and / or slots. Such openings may be made according to known techniques of those skilled in the art, such as in particular laser cutting techniques or water jet cutting. According to different types of design, the orifices can act simultaneously as an air supply and as an outlet for flames, or be divided into two categories, the first forming the entrance of air and the second the exit of the flames.
  • the hob is suitable to bear directly, that is to say without intermediate elements, cooking utensils or containers above the gas burner.
  • a first variant of the invention provides that the area covering the gas burner is able to contribute to the support of cooking utensils.
  • this zone covering the gas burner may comprise at least an elevated part on which at least a part of cooking.
  • a second variant provides for the hob to have bosses distributed around the periphery of the area covering the gas burner.
  • cooking utensils can rest on these bosses which for a good stability of the cooking utensils are preferably at least in number three.
  • the invention provides a combination of the first two variants, namely that the area covering the gas burner is intended to support cooking utensils in combination with bosses distributed at its periphery.
  • a first conception of the invention consists in producing the plate of cooking in at least two distinct elements, a first element essentially plane and having at least one opening, in which will be housed the gas burner, and a second member for closing said opening and forming at least a portion of the area covering the gas burner.
  • the second element can have the shape of a hat whose geometry remains arbitrary and chosen in particular from an aesthetic point of view; the general form of this element can for example be circular, parallelepipedic, star-shaped, etc ...
  • This hat can be formed from a substantially higher part flat and elevated in relation to the plane of the first element, at least contribute to the support of cooking utensils, and side walls vertical or slightly inclined.
  • the top of the hat that can contribute to the support of cooking utensils can either be smooth or present a relief allowing for example to avoid slippage.
  • the orifices are formed in the second element which can have the shape of a hat and more particularly in the side walls of it.
  • This assembly formed by the two elements constituting the cooking plate must have a good seal at the junction of the two elements so that the water, for example used to clean the apparent surface of the cooking plate, does not penetrate not inside.
  • a plate used for the preparation of food it is necessary to avoid any risk of fouling not to see appearing germ developments. It is thus advantageously provided to perform the assembly of the two elements by means of a seal, for example to produce silicone, deposited on the first substantially planar element, the second element coming into contact with this seal which is crushed by the weight of said second element, sealing being thus achieved.
  • the cooking plate is essentially flat and has at least one deformed zone which has orifices and which covers the gas burner. More preferably, the deformed zone represents, with respect to the main plane of the plate, at least one hump and / or hollow.
  • This deformation of the plate advantageously comprises a substantially flat portion and raised relative to the main plane of the plate.
  • it comprises substantially vertical or inclined lateral walls on which the orifices are formed.
  • FIG. 1 represents a glass ceramic plate 1 made in one piece unique and planned to constitute four gas fireplaces at the level of the four locations 2 which are in relief on the plate.
  • the plaque ceramic glass 1 also has four holes 3 which are provided for the passage of the axes of the controls of the gas burners.
  • the presence of holes 3 and their location should not lead to a limiting interpretation of the invention; indeed they may not be present, for example when controls are installed regardless of the plate or when it comes to sensory commands, and when present their distribution can be different.
  • the four locations 2 are made according to the technique taught by FR-B-2,735,562 which describes a method for producing bosses by deformation forming an integral part of the vitroceramic plate.
  • the glass-ceramic plate is completely cover the gas burners, which are set up in a box or support frame not shown in the figures, to form an apparatus for cooking.
  • this type of ceramic hob gas burners whose manufacture is simplified or at least reduced; indeed, it is possible to provide a deformed part 2 of the glass-ceramic plate constitutes at least the upper part of the combustion chamber of the burner gas.
  • the deformations 2 carried out also serve to support cooking utensils such as pans.
  • Diameters that can contribute to the support are provided with varying diameters from one location 2 to another as it exists on more traditional cooking appliances; indeed, the diameters of the elements of support or more precisely the diameters of the gas burners are usually provided with variable dimensions on the same device cooking to be suitable for cooking utensils or pans of different dimensions.
  • the upper surfaces 4 of the deformations 2 intended to cover gas burners were made flat to offer a stable support for utensils such as pans.
  • the surface of a deformation can itself present a relief more or less pronounced to be a roughness and prevent all slip, or to constitute point supports between which the air or the flue gas can circulate under the bottom of the cookware.
  • the deformations 2 are consisting of an upper part 4 and a lateral part 5 which forms a plane inclined.
  • This inclined plane further comprises slots 6 distributed over the periphery of the deformation 2.
  • These slots 6 are made after the deformation of the plate by any means known to those skilled in the art, such as water jet cutting or laser cutting.
  • the invention also provides according to other embodiments of making the orifices or slots 6 before the deformation of the plate. These slots 6 are provided on the one hand to form the outlets from the flames and secondly to allow an air intake to level of the gas burner.
  • all of these orifices 6 formed on the lateral parts 5 of the deformations 2 have a internal form, not shown in the figures, for example provided on the area lower 7 which forms a barrier against the penetration of liquid to the gas burner.
  • Such an internal shape may be a simple inclined plane or a more complex shape defined in particular by the shape of the orifices 6 of their positions and the inclination of the side wall 5.
  • This internal form of orifices 6 can be obtained directly during the cutting of the orifices 6 or by subsequent shaping.
  • Such an embodiment of the glass-ceramic plate 1 according to the invention therefore a surface made of a single material and according to this embodiment of a unique element, which in addition to its innovative appearance for cooking appliances with gas burners, will simplify very advantageously the maintenance of such a device, compared to the products that exist today.
  • an assembly with the box which allows easy access to the burners provides, for example, a device of the hinge type which allows the complete lifting of the ceramic hob 1 without dissociating it totally of the box and therefore without any problem of putting back in place or repositioning.
  • a device of the hinge type which allows the complete lifting of the ceramic hob 1 without dissociating it totally of the box and therefore without any problem of putting back in place or repositioning.
  • Such a device is naturally accompanied by seals adapted over the entire periphery to ensure watertightness when the ceramic hob 1 is in operating position.
  • the vitroceramic plate 1 shown in the figures must not lead a limiting interpretation of the invention; indeed, the invention is aimed at types of ceramic hob for covering at least one gas burner.
  • Such a plate may therefore comprise a single location 2 or more in function of the cooking appliance to be achieved, the realization with four locations being just one example.
  • the ceramic hob can also be intended to cover, in addition to one or more gas burners, other types of cooking elements such as radiant electric elements, halogen and / or induction.
  • the inventors have also considered keeping such a plate vitroceramic 1, that is to say having four deformed locations 2 when for example two gas burners are associated with two heating elements electric radiant, halogen and / or induction, possibly without forming the holes above the electrical elements.
  • a plate vitroceramic 1 that is to say having four deformed locations 2 when for example two gas burners are associated with two heating elements electric radiant, halogen and / or induction, possibly without forming the holes above the electrical elements.
  • Such an embodiment makes it possible maintain a homogeneous general appearance of the ceramic hob. It is It is also possible to make such deformations 2 only over gas burners and to keep a flat plate as long as it covers electrical elements to ensure the recognition of different areas.
