Definitions
- the invention relates to a hob intended to equip a cooking appliance such as a hob comprising at least one gas burner.
- the hob is made of glass ceramic or another material resistant to high temperature and having a low coefficient of expansion.
- Such gas burners are usually arranged in a usually metallic structure called "box” and covered by a glass-ceramic plate equipped with a frame which closes the structure.
- the aim of the design of these cooking appliances was to replace more traditional cooking appliances, most often made up of an enamelled sheet on which the gas burners are positioned and a metal grid covering them.
- Document DE-U 298 05 620 describes such a cooking appliance and more particularly mounting means making it possible to fix the gas burners to the ceramic hob with gaskets to make the connection between the ceramic hob and the gas burner.
- Patent WO97 / 00407 also describes such a cooking appliance in which the gas burners are surrounded by elements for supporting kitchen utensils used for cooking food.
- Patent FR-B-2 735 562 describes cooking appliances comprising a ceramic hob ensuring the support of gas burners and also making it possible to provide the support function for cooking utensils.
- the inventors have thus given themselves the mission of offering the possibility of providing a cooking appliance comprising at least one gas burner and the upper part of which is formed by a cooking plate, such as a ceramic hob, for which the cleaning is made even simpler than what currently known products allow.
- a cooking plate such as a ceramic hob, intended to equip a cooking appliance comprising at least one gas burner, said ceramic hob comprising an area intended to cover the burner.
- gas and said zone comprising orifices, provided in particular to form an air intake towards the gas burner and to allow the flame to escape.
- the gas burner is completely masked by the plate cooking and therefore invisible to the user; such a design doubly simplifies the cleaning of the cooking appliance.
- the gas burner which is hidden is protected from dirt and therefore less subject to fouling.
- the user cleans the exposed part of the cooking appliance, he simply has to carry out the cleaning of the hob, which considerably simplifies the operation compared to cleaning the cooking appliances currently available.
- the cooking appliance giving a new aesthetic appearance which goes in the direction of developments in recent years, namely a smooth appearance and as little as possible of visible functional elements.
- the cooking appliance comprising a gas burner only reveals orifices which are, as said above, provided on the one hand to allow an air supply to the burner and on the other hand, to allow the formation and exit of the flames on the upper surface of the hob so as to heat the cooking utensils.
- the orifices are holes and / or slots.
- Such orifices can be produced according to techniques known to those skilled in the art, such as in particular laser cutting techniques or water jet cutting techniques.
- the orifices can either act simultaneously as an air inlet and as an outlet for the flames, or be divided into two categories, the first forming the air inlet and the second the flame outlet.
- the cooking plate is capable of supporting 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 capable of contributing to the support of the cooking utensils.
- this zone covering the gas burner may comprise at least one raised part on which a cooking utensil can rest at least partly.
- a second variant provides that the cooking plate has bosses distributed around the periphery of the area covering the gas burner. In this way, cooking utensils can rest on these bosses which for good stability of the cooking utensils are preferably at least in number of three.
- the invention provides a combination of the first two variants, namely that the zone covering the gas burner is designed to support cooking utensils in association with bosses distributed around its periphery.
- a first design of the invention consists in producing the hob in at least two distinct elements, a first element which is essentially flat and comprising at least one opening, in which the gas burner will be housed, and a second element intended to close off said gas burner. opening and forming at least part 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 shape of this element can for example be circular, parallelepiped, star-shaped, etc.
- This cap can be formed by a substantially planar upper part and raised relative to the plane of the first element, which can in particular contribute at least to support cooking utensils, and vertical or slightly inclined side walls.
- the upper part of the hat which can contribute to the support of cooking utensils can either be smooth or have a relief making it possible, for example, to prevent slipping.
- the orifices are formed in the second element which can have the shape of a cap and more particularly in the side walls of the latter.
- This assembly formed by the two elements constituting the hob must have a good seal at the junction of the two elements so that water, for example used to clean the visible surface of the hob, does not penetrate not inside.
- water for example used to clean the visible surface of the hob
- it is necessary to avoid any risk of fouling so as not to see the appearance of germ development.
- the fixing of one element relative to the other can advantageously be simply obtained by the weight of the second element and an indexing thereof with respect to the first element. It is thus possible to form a barrier in particular to water and the fixing being simple, it is possible at any time to separate the two elements for more intense cleaning and in particular to avoid the formation of germ at the level of the seal.
- the cooking plate is essentially flat and has at least one deformed zone which has the 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 bump and / or a hollow.
- This deformation of the plate advantageously comprises an essentially flat and raised part relative to the main plane of the plate.
- it has substantially vertical or inclined side walls on which the orifices are formed.
- the deformed zone can have a general shape independent of its function and which can be chosen arbitrarily.
- the upper part which can advantageously be flat and contribute at least in part to the support of cooking utensils, can either be smooth or have a relief.
- This embodiment of the invention in a single element having at least one deformed zone can be carried out according to the teaching of document FR-B-2 735 562.
- said hob associated with a gas burner, only leaves openings.
- a gas burner more particularly suited to this design is a burner with a high primary ventilation rate.
- the inventors have also planned to simplify the gas burner by using the zone which covers it to form a part of the combustion chamber thereof. Indeed, for example the deformed zone of the hob can constitute the upper part of the combustion chamber.
- this deformed zone also replaces the part of the burner which has orifices where form the flames, said deformed zone which, according to certain embodiments of the invention, may itself include orifices provided for the passage of the flames.
- the inventors also plan to associate this design with electric heating elements such as radiant elements, placed in between the gas burner and the hob.
- the electric heating element can be fixed for example on the upper part of the combustion chamber of the gas burner. This type of embodiment can make it possible to substitute electric heating for gas heating, for example in order to simmer a dish.
- the invention also provides for the production of cooking plates intended to equip mixed cooking appliances, that is to say which may include gas cooking locations, associated with radiant, halogen and / or electric cooking locations. induction.
- mixed cooking appliances that is to say which may include gas cooking locations, associated with radiant, halogen and / or electric cooking locations. induction.
- the inventors advantageously plan to make all the zones intended to cover a cooking location in the same way, that is to say in accordance with what has just been described, in order to offer an appliance. with a homogeneous appearance.
- FIGS. 1 and 2 represent:
- FIG. 1 a schematic perspective view of a glass ceramic plate produced according to the invention, Figure 2, an enlarged view of part of Figure 1.
- the figures are not shown to scale to facilitate the comprehension.
- FIG. 1 represents a glass-ceramic plate 1 produced in a single piece and intended to constitute four gas fireplaces at the level of the four locations 2 which appear in relief on the plate.
- the ceramic hob 1 also has four holes 3 which are provided for the passage of the axes of the gas burner controls.
- the presence of the holes 3 and their location should not lead to a limiting interpretation of the invention; in fact they may not be present, for example when the controls are installed independently of the plate or when it is a question of sensitive controls, and when present their distribution may be different.
- the four locations 2 are produced according to the technique taught by patent FR-B-2 735 562 which describes a process for producing bosses by deformation forming an integral part of the glass-ceramic plate.
- the ceramic hob will completely cover the gas burners, which are placed in a box or support frame not shown in the figures, to form a cooking appliance.
- this type of ceramic hob gas burners the manufacture of which is simplified or at least reduced; in fact, it is possible to provide that a deformed part 2 of the ceramic hob constitutes at least the upper part of the combustion chamber of the gas burner.
- the deformations 2 carried out also have the function of supporting cooking utensils such as pans.
- the diameters likely to contribute to the support are provided with diameters that vary from one location 2 to another, as is the case with more traditional cooking appliances; in fact, the diameters of the support elements or more exactly the diameters of the gas burners are usually provided with variable dimensions on the same cooking appliance in order to be able to be adapted to cooking utensils or pans of different dimensions.
- the upper surfaces 4 of the deformations 2 intended to cover the gas burners have been made flat to offer stable support to utensils such as pans.
- the surface of a deformation may itself have a more or less pronounced relief either to constitute a roughness and to prevent any slippage, or to constitute point supports between which the air or the combustion gases can circulate under the bottom of the cookware.
- the deformations 2 according to this embodiment of the invention consist 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 produced 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 alternative embodiments, for producing the orifices or slots 6 before the deformation of the plate. These slots 6 are provided on the one hand to form the flame exit orifices and on the other hand to allow an air intake at the level of the gas burner.
- all of these orifices 6 formed on the lateral parts 5 of the deformations 2 have an internal shape, not shown in the figures, for example provided on the lower zone 7 which forms a barrier against the penetration of liquid towards the gas burner.
- Such an internal shape can be a simple inclined plane or a more complex shape defined in particular as a function of the shape of the orifices 6 in their positions and of the inclination of the side wall 5. This internal shape of the orifices 6 can be obtained directly during cutting the orifices 6 or by subsequent shaping.
- Such an embodiment of the ceramic hob 1 according to the invention therefore offers a surface made of a single material and according to this embodiment of a single element, which in addition to its innovative appearance for cooking appliances comprising gas burners, will allow very advantageously to simplify the maintenance of such a device, compared to the products which exist today.
- the inventors have advantageously provided for assembly with the box which allows easy access to the burners; such an assembly provides for example a device of the hinge type which allows the complete lifting of the glass ceramic plate 1 without completely dissociating it from the casing and therefore without any problem of repositioning or repositioning.
- Such a device is naturally accompanied by seals adapted over the entire periphery to ensure sealing when the glass-ceramic plate 1 is in the operating position.
- the glass-ceramic plate 1 presented in the figures should not lead to a limiting interpretation of the invention; indeed, the invention relates to all types of ceramic hob intended to cover at least one gas burner. Such a plate can therefore have a single location 2 or more depending on the cooking appliance to be produced, the production with four locations being only 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, halogen and / or induction electric elements.
- the inventors have also considered keeping such a ceramic hob 1, that is to say comprising four deformed locations 2 when, for example two gas burners are associated with two radiant, halogen and / or induction electric heating elements, possibly without form the holes above the electrical elements.
- Such an embodiment makes it possible to maintain a general homogeneous appearance of the ceramic hob. It is also possible to carry out such deformations 2 only above the gas burners and to keep a flat plate as soon as it covers electrical elements to guarantee recognition of the different zones.
