    The present invention relates to a worktop, or worktable or countertop or furniture, formed of at least one large plate positioned or intended to be positioned horizontally on one or more support elements (cabinet of a piece of furniture, foot ( s) support (s)) to provide a stable surface for different uses. In particular, the present invention relates to a table or a piece of furniture having a surface or plate capable of simultaneously or successively allowing different activities and / or support of objects, in particular that may allow the cooking or reheating of food in suitable containers. and offer other uses.
    The materials usually used for making worktops are for example wood, quartz, Corian®, etc. For cooking food, there are also large cooking surfaces in kitchens, especially for professional use, these plates are usually metal and / or composite. In particular, there are multilayer panels, based on layers or ceramic materials such as sandstone, layers or aluminum-type metallic materials and layers or insulating plastic materials Bakelite type, these panels generally having a significant thickness (of order of 12 mm for example) and being of complex construction.
    At the same time, hobs made of vitroceramic or reinforced glass type materials, of more limited dimensions (in particular with a surface area generally of less than 0.4 m 2, top surface plates that may be more difficult to obtain by the processes usually used, and which may pose problems in terms of flatness, handling, etc.), exist for uses in particular domestic, the use of glass ceramic material has become widespread in recent years for the cooking plates, due in particular to the performance of this material for this use and attractive appearance of the plates made.
    There are currently different types of glass ceramic plates, each variant being the result of important studies and numerous tests, since it is very difficult to make modifications on these plates and / or on their method of obtaining without risking an adverse effect on the properties sought: to be able to be used as a hob, a glass-ceramic plate must generally have a transmission in the wavelengths of the visible range that is low enough to mask at least a part of the heating elements underlies the rest and high enough that, depending on the case (radiant heating, induction heating, etc.), the user can visually detect the heating elements in working order for safety purposes; it must also have a high transmission in the wavelengths of the infrared range in the case in particular radiant hob plates. The plates thus designed are intended exclusively for use as hobs and are not traditionally intended to receive objects other than heat-resistant utensils used for cooking food, nor intended for exercise other activities than cooking food.
    The present invention has sought to expand the range of existing household equipment products, for domestic or professional use, by developing a new type of interactive products for more varied uses.
    This object has been achieved by the new equipment or article or installation according to the invention, advantageously interactive, this furniture / household equipment comprising: - at least one working plane (or counter or table) formed of at least one substrate (in particular plate or surface or plate) in (or (based on) one or substantially consisting of a) glass material (preferably glass-ceramic) transparent (having in particular a light transmission greater than 60%) monolithic (or monobloc or in one piece), advantageously essentially plane, surface (length by width of its face of larger dimensions) greater than 0.7 m2, provided with a coating so that the substrate provided with the coating has a blur greater than 15%, a light transmission TL less than 60%, and an opacity indicator greater than 85, - at least one heating element (in particular under the substrate and hidden by it when this heating element is not in operation / is at rest), - at least one communication interface with at least one element of the plane (for example with the heating element or elements), and / or where appropriate with at least one an external element (out of the plane), for example with an external module (unit, device) for wireless communication, said equipment being furthermore devoid of light source (s) (or for use (exclusively) lighting).

    More generally, the invention also relates to a work surface formed of at least one monolithic transparent glass material substrate with an area greater than 0.7 m2, provided with a coating so that the substrate provided with the coating has a superior blur at 15%, a TL light transmission of less than 60%, and an opacity indicator greater than 85, this work plan being intended to equip a piece of furniture or interactive multi-purpose equipment (intended for several uses as listed in the previous paragraph) ) as defined above according to the invention. The invention also relates to the use of a substrate, in particular a plate, made of a monolithic transparent glass material with a surface greater than 0.7 m2, provided with a coating so that the substrate provided with the coating has a soft focus. greater than 15%, a TL light transmission of less than 60%, and an opacity indicator greater than 85, as an interactive multi-purpose work plan as mentioned in the above paragraphs.
    As indicated above, the work surface is formed of a substrate or plate of monolithic glass material (the glass material having been formed in one piece / in one piece, even if the substrate may, if necessary, have recesses, generally used in the already formed part, for aesthetic or functional purposes) of large dimensions, the advantage of such a monolithic plate of large dimensions being in particular to provide a predominantly continuous / uniform surface / without connections, aesthetic and easy maintenance, as well as greater comfort of use and greater safety (in terms of sealing in the event of a liquid spill, etc.), etc. The substrate consists essentially, if not solely, of the glass material, this substrate / glass material possibly being able to be provided with decorative or functional coatings of small thickness (in particular of the order of a few tens of nanometers to a few hundred microns, even more), for example in enamel, paint, thin layers, etc., as specified later.
    Unlike the use in vitroceramics in particular, this (substrate) glass material is large, its surface (corresponding to the product of its length by its width for its face of larger dimensions - usually its upper face, intended to be Apparent and serve as support articles (household or work or cooking) being larger than 0.7 m2, preferably greater than 0.9 m2, especially greater than 1 m2, especially greater than or equal to 2 m2. The manufacture of large plates, in the case of glass-ceramics in particular, poses numerous problems with regard to flatness and handling.In the present invention, a plate of large dimensions, having however a good flatness, can nevertheless be advantageously obtained by reducing the speed of passage (or lengthening the arch of ceramization or increasing the residence time in the arch) relative to the speed (or the length of the arch or time standard) usually used to obtain vitroceramic plates of usual dimensions less than 0.4 m2, as explained later in the method according to the invention.
    The substrate / glass material according to the invention is advantageously plane (or predominantly or almost planar), and in particular has a flatness (height between the highest point and the lowest point of the substrate relative to the mean plane of the substrate, with the exception of possible voluntary deformations made on the substrate for aesthetic or functional purposes) less than 0.1% of the diagonal of the substrate, and preferably less than 3 mm, especially less than 2 mm, in particular less than 1 mm. mm, or even of the order of zero, depending on the size / surface / diagonal of the substrate, the flatness being measured using a reference waveform SurFlat sold by the company Visuol. The substrate is generally of geometric shape, in particular rectangular, even square, or even circular or oval, etc., and generally has an "upper" face (visible face) in the use position, another "lower" face (generally hidden , in the frame or cabinet of the furniture incorporating the worktop) in the use position, and a slice (or edge or thickness). The upper face is generally flat and smooth but may also have at least one raised zone and / or at least one hollow zone and / or at least one opening and / or beveled edges (these shapes having been added during manufacture of the substrate, for example by rolling or collapse or pressing, etc., or having been added in recovery), etc., these shape variations advantageously constituting continuous variations of the plate (without changing materials or connections). The lower face may be particularly smooth or provided with pins increasing its mechanical strength and obtained for example by rolling. The thickness of the monolithic substrate made of glass material used is generally at least 2 mm, in particular at least 2.5 mm, in particular is of the order of 3 to 30 mm, and advantageously is less than 15 mm, in particular is of the order of 3 to 15 mm, especially 3 to 10 mm.
    The glass material of the substrate used is advantageously resistant to high temperature and / or has a coefficient of expansion that is zero or almost zero (for example less than 15 × 10 -7 K -1), in particular is advantageously glass-ceramic or reinforced glass ( especially chemically or thermally quenched). Preferably, the substrate is a glass-ceramic substrate. As defined according to the invention, the glass material is advantageously transparent, in particular has a light transmission TL greater than 60%, especially greater than 80%, as defined according to the invention.
    The glass-ceramic used can be in particular of composition as described in the patent applications published under the following numbers: WO2013171288, US2010167903, WO2008065166, EP2086895, JP2010510951, EP2086896, WO2008065167, US2010099546, JP2010510952, EP0437228, this glass ceramic being in particular a glass ceramic of lithium aluminosilicate.
    The glass-ceramic can be refined with arsenic (that is to say (mother glass of) composition comprising of the order of 0.2% to 1.5% by weight of arsenic oxide (expressed as AS2O3), or can be unenriched with arsenic (in particular having an arsenic oxide content of less than 0.2%, in particular less than 0.1%, or even zero) or refined with tin or refined with the sulphide (s). ), and can be obtained by rolling or floating.
    The glass material may also be a non-ceramic tempered glass, for example a lithium aluminosilicate hardened and colored in the mass as described in the patent applications published under the following numbers: FR1060677, WO2012080672, or a tempered glass of a other type (soda-lime, borosilicate, etc.), for example as described in the application published under the number WO2012146860.
    The glass-ceramic or tempered glass are obtained by the respective processes described in the aforementioned documents by using the cycles and processing temperatures to obtain the glass material having the selected characteristics given in the definition of the invention. In the case of glass-ceramics, these methods are preferably modified by reducing the rate of passage by at least 25%, preferably by at least 50%, or by increasing the length of the ceramic arch or the residence time. in said arch by at least 25%, preferably at least 50%, respectively, with respect to the speeds, lengths and times normally used, in order to obtain a large planar substrate as required according to the invention, as explained later. The transparent glass-ceramic substrate generally comprises crystals of β-quartz structure within a residual vitreous phase, the absolute value of its coefficient of expansion being advantageously less than or equal to 15 × 10 -7 / ° C., or even 5 × 10 -7 / ° C, this glass ceramic being for example that of the plates marketed under the name KeraLite by the company Eurokera.
    The glass material may optionally also include dyes giving particular colorations to the substrate, for example vanadium oxide, iron oxide, cobalt oxide, cerium oxide, selenium oxide, chromium oxide, or even nickel oxide, copper oxide and / or manganese oxide, etc.
    As indicated in the definition of the invention, the substrate / glass material is provided with a coating so that the assembly has the characteristics defined in the invention, this coating serving in particular as a masking means for masking at least a part underlying elements (heating means at rest in particular), and where appropriate to provide opacity / low transmission and / or blur suitable in particular for the detection of the heating elements when they are activated.
    The coating is advantageously in the form of at least one layer of paint or thin layers on at least a part or most or all of the lower face of the glass material, in particular a layer of paint of the order of 5 to 500 μm thick, in particular 5 to 50 μm thick. The paint used preferably has a thermal withstand greater than 350 ° C. (generally between 350 ° C. and 500 ° C.), and is for example based on silicone resin (s), in particular alkyd resin (s). (s) silicone (s) (that is to say one or more silicone resins modified by the incorporation of resin (s) alkyd (s)), maybe even based on other resins such as epoxy or polyurethane, for uses at low temperatures below 200 ° C, this paint may include, where appropriate, pigments, preferably pigments for enamels (in proportions not exceeding 50% by weight) depending on the desired color. Alternatively, this coating may also be in the form of at least one enamel layer on the upper face of the glass material. The substrate thus coated may be, for example, of the type sold under the name KeraResin by Eurokera.
    As defined according to the invention, the coated substrate forming the working plane is selected so as to have a blur greater than 15%, in particular greater than 40%, or even greater than 60%, a TL light transmission of less than 60%, in particular less than 50%, or even less than 30% (this light transmission being in particular non-zero / greater than 0) and an opacity indicator greater than 85, preferably greater than 90 (and in particular less than 100). The substrate has these characteristics on the essential (in particular on at least 80%, or even 100%) of its surface, with the exception of any localized additional decorations (for example enamel) or localized components applied to its surface.
    The blur measures the level of light scattering and is defined, in the context of the invention, as the ratio of the diffuse transmission on the total transmission at a wavelength equal to 550 nm, this blur being evaluated for example at using the spectrophotometer with an integrating sphere used for light transmission measurements.
    The TL light transmission is measured according to ISO 9050: 2003 using illuminant D65, and is the total transmission (integrated in the visible range), taking into account both the direct transmission and the possible diffuse transmission. , the measurement being made for example using a spectrophotometer provided with an integrating sphere, the measurement at a given thickness then being converted, if necessary, to the reference thickness of 4 mm according to the ISO 9050: 2003 standard. . The indicator (or factor or coefficient) of opacity Ω is determined in the present invention by the formula Ω = 100 - ΔΕ * and is evaluated by measuring (colorimetry in reflection carried out using a Byk-Gardner Color colorimeter Guide 45/0) the color variation ΔΕ *, corresponding to the difference between the color, measured in reflection on the upper surface of the substrate, for the substrate placed on an opaque black background and that for the substrate placed on an opaque white background (ΔΕ * = ((Ln * -Lb *) 2 + (aN * -aB *) 2 + (bN * -bB *) 2) 1/2 according to the formula established in 1976 by CIE, LB *, aB *, bB * being the colorimetric coordinates of the first measurement on a white background and LN *, aN *, bN * being those of the second measurement on a black background in the colorimetric system established in 1976 by the CIE).
    The coated substrate according to the invention makes it possible, where appropriate, to indicate the cooking zones when they are in working order, this substrate masking at the same time the elements placed below (such as the heating elements and cables).
    As defined above, the article according to the invention also comprises at least one heating element (or heating element), for example one or more radiant or halogen foci or one or more gas burners and / or one or more heating means by induction, these heating means being generally located under the work plan and hidden by it at rest. The work plane of the article according to the invention may comprise one or more heating elements, as well as one or more lights. By the term "fire" is meant a cooking location. The article according to the invention may comprise several types of heating elements or fires (gas fires, radiant, halogen or induction fires). Preferably, the article according to the invention comprises as heating element (s) one or more induction heating means.
    The heating means may be located in a defined area (for example on one end of the substrate) or several areas of the substrate, or may be uniformly distributed under the substrate, occupying for example at least 25% of the surface of the substrate, may even occupy a surface almost equivalent to that of the substrate (for example more than 50%, especially more than 75%, or even more than 85%, or even 100% of the main surface of the substrate), a plurality of small inductors dimensions lining for example the substrate under its underside, to allow heating if necessary in any area.
    The cooking locations on the work surface, directly above the heating means, may be indicated (or not, in the case for example of a plan provided with heating means covering the whole of its area), on activation and / or permanently, in particular by means of a fixed decoration, for example enamel. The dimensions of the patterns used to indicate the cooking zones (as well as those of patterns that can indicate other zones or functions or to create decorations) may be more or less important, for example they may be circles delimiting each of the zones. heating elements, or small patterns (triangles, crosses, etc.) at their center or at their base, etc. The absence of light sources, integrated into the equipment, to signal for example the heating zones (these being indicated if necessary by fixed patterns in the present invention) or to illuminate displays or other lighting effects , has the advantage of being more economical, easier to maintain the equipment, to offer greater safety and simplicity of handling of the equipment, said equipment being generally intended to be used in environments already filled lighting (natural or artificial, such as a living room, a terrace, etc.).
    Preferably, the cooking locations (and / or where appropriate other zones and / or elements and / or functions and / or decorations) are thus permanently indicated by a pattern (in particular of the circle circle, cross, triangle type). , rectangle, or other non-geometric decoration, etc.) fixed, obtained in particular by deposition of layer (s) (in particular such (s) as that (s) used (s) for the decoration of glass-ceramics), for example in enamel or possibly paint, on the surface of the plate (in particular on the upper face, or possibly on the lower face depending on the type of coating).

    Preferably, the interface allows wireless communication with a unit outside the work plane (this unit can be part of the equipment according to the invention and can itself be an interface), allowing for example the activation to distance from the heating zones and / or the control of different functions (increase or decrease in power or heating time, etc.), the commands given by the outdoor unit being transmitted by the interface to the relevant components of the equipment. The interface may also be a control interface located at the plane (control panel) transmitting the commands by wire or possibly without wires to other components of the plane or out of the plane. The outdoor unit in the case of a remote control can be for example in the form of a keyboard, a tablet or a touch screen, a mobile phone, this unit can be fixed (for example fixed on a wall) or mobile (can be placed on the worktop if necessary). This embodiment has the particular advantage of avoiding fingerprints (unsightly and visible on glass materials) on the worktop or cooking zones. Activating the remote controls also reduces the risk of burns by avoiding manipulation of the controls near the cooking zones. In particular for safety concerns, the wireless communication may advantageously be provided to be limited in scope (for example limited to the volume of the room in which the equipment is located) and / or provided with security to prevent inadvertent activation. by a person not present. The wireless communication is carried out in particular by electromagnetic or radio waves, if necessary using Bluetooth, WLAN, wifi, RFID chip type systems, etc. The interface can make it possible to transmit different signals initiated by contact or even by movement to activate different components (for example it can convert a movement, detected by sensors by triangulation, these sensors being connected to this interface (and by being part of it). appropriate), when activating a function (for example increasing the heating power, etc.).
    At least one interface is generally located on or under the work plane or nearby. The equipment according to the invention can also comprise several interfaces, of the same type or different, allowing for example the activation of different elements, or the equipment can comprise several interfaces, functioning if necessary differently (of different constitution, operating at different frequencies, etc.) to control the same element (for example a heating zone) with a reinforced level of security. The interface may be formed of sensor (s), connector (s), control element (s), any other electrical or electronic or electromagnetic component, etc. One or more control means or zones (in the form of keys, logos, or even keyboards, etc.) or indicators (intensity / power, time, etc.), which can be activated for example by contact on the surface of the plane or remotely (in particular by wireless communication), or by simple movement of the hand as already mentioned (by sensors located where appropriate outside and recording the movement, for example by triangulation, to convert, including using a suitable algorithm and interface, for example when activating a function), or where appropriate by placing a specific object (pan, etc.) at a specific location (such as cooking zone) of the plate, can be connected to or be part of the interface (s).
    Preferably, the equipment according to the invention comprises at least one communication interface with at least one external element for the activation of different zones and / or functions of the substrate by wireless communication, in particular when the TL light transmission of the substrate is weak.

The equipment, in particular the work surface, according to the invention may also comprise various functional and / or decorative coatings, in particular those generally used with the glass materials concerned, for example enamel, paint, diaper (s) thin (for example metallic (s), dielectric (s), etc.), etc. For example, one of the faces of the substrate may comprise one or more layers or one or more enamel patterns, for decorative purposes and / or to signal one or more elements (displays, cooking zones, etc.), and / or or serving as a coloring layer or masking and / or for other functions. In particular, the work surface may be provided with a functional layer giving it one or more additional properties such as anti-scratches, mechanical reinforcement, anti-traces, anti-overflow, etc. The coating may be carried out for example by methods such as screen printing, sputtering or pneumatic deposition, ink jet or enamel, etc., the coating can be applied in particular on the visible face or on the opposite face, depending on the type of coating and the desired function. For example, in the case of an enamel decoration, it is preferentially deposited on the upper face for reasons of visibility in particular, while an opacifying layer (such as the coating mentioned according to the invention) is preferably deposited on the opposite face not visible for better protection against abrasion, etc.
    The present invention also relates to a method of manufacturing an equipment according to the invention, in particular the working plane of said equipment, when this working plane is formed of at least one glass-ceramic substrate with an area greater than 0.7 m2, in wherein at least one ceramization cycle of a glass plate with a surface area greater than 0.7 m2 is carried out to obtain said substrate, and wherein the passage rate is reduced by at least 25%, preferably by at least 50% , or the length of the ceramic arch or the residence time in said arch is increased by at least 25%, preferably by at least 50%, with respect to speed, length or residence time respectively. optimal or customary to obtain a glass ceramic substrate of less than 0.4 m2 surface area.
    As a reminder, the manufacture of the glass-ceramic plates generally takes place as follows: in a melting furnace, the glass of the chosen composition is melted to form the glass-ceramic, and then the molten glass is rolled into a standard ribbon or sheet by passing the glass melted between rolling rolls and cut the glass ribbon to the desired dimensions. Alternatively to rolling, the glass can be floated, as described for example in the patent application WO2008056080, before being optionally cut. The plates, already cut or not, are then ceramized in a manner known per se, the ceramization of baking the plates according to the thermal profile chosen to transform the glass into the polycrystalline material called "glass-ceramic" whose expansion coefficient is zero or almost -nul and which withstands a thermal shock up to 700 ° C. The ceramization generally comprises a stage of gradual raising of the temperature to the nucleation range, generally located in the vicinity of the glass transformation domain, a step of crossing in several minutes of the nucleation interval, a new progressive elevation of the temperature up to the temperature of the ceramic bearing, the maintenance of the temperature of the ceramic bearing for several minutes and a rapid cooling to room temperature. If necessary, the method also comprises a cutting operation (generally before ceramization), for example by water jet, mechanical tracing with the wheel, etc. followed by a shaping operation (grinding, beveling, ...). The method may also include a rolling or collapsing step to form particular reliefs.
    In the present invention, the vitroceramic follows a ceramization cycle giving it the desired properties, in particular a transparent appearance. Other details and advantageous features will emerge below from the description of a non-limiting embodiment of the invention with reference to the accompanying drawings, in which: FIG. 1 represents a schematic perspective view of a device according to FIG.

These decorations, for example in the form of colored circles (9) delimiting each location (the colors possibly being identical or different depending on the locations) and surrounding the inductors allow for example to indicate the cooking locations to avoid their contact when the heating elements are activated. They can also consist of information, logos, images (11), etc. The equipment further comprises at least one communication interface (12) (hidden by the substrate) with the heating elements, this interface also communicating wirelessly with an outdoor unit in the form of, for example, a touch pad (13). ) for activating different zones and functions of the plate or equipment. The outdoor unit can be advantageously movable and rest on the work plane (Figure 1) or used for remote activation (Figure 3) of different areas or functions. Alternatively or cumulatively, the interface could also include or be connected to a fixed control panel located on the surface of the substrate (2) for the activation of different zones and functions, in particular of the substrate.
