    DESCRIPTION
    The present invention refers to a cooking field device according to the preamble of claim 1.
    Through the state of the art, a cooking field device with a lighting unit is already known, which has multiple luminous elements. In an operating state, the luminous elements illuminate a partial surface area of a cooking field plate. The light elements are made as LEDs (light emitting diodes) and are part of an LED display of a cooking field user interface. In the mounted state, the luminous elements are directly adjacent to each other and have a distance between their central points of much less than 1 mm. Each of the luminous elements provides punctual lighting.
    The present invention solves the technical problem of providing a generic cooking field device with better properties in relation to its lighting. According to the invention, this technical problem is solved by the features of claim 1, while advantageous embodiments and improvements of the invention can be extracted from the secondary claims.
    The present invention refers to a cooking field device, in particular, to an induction cooking field device, with at least one cooking field plate and with at least one lighting unit, which has multiple luminous elements , which in the installation position are arranged as a matrix under the cooking field plate and which illuminate at least a partial surface area of the cooking field plate in at least one operating state, where two luminous elements directly adjacent to each other in at least one direction have in the direction a distance between their central points of at least 1 mm, preferably, at least 1.5 mm, advantageously, at least 2 mm, particularly advantageous, at least 2.5 mm and, preferably, at least 3 mm.
    By means of such an embodiment, advantageous lighting can be achieved. Thanks to the minimum distance between the central points, it is possible that the quantity of luminous elements is small compared to a surface extension to be illuminated, whereby the costs can be low.

In the operating state, the shielding unit largely or completely prevents interference between the light emitted by a first light element of the two light elements directly adjacent to each other and the light emitted by a second luminous element of the two luminous elements directly adjacent to each other. In particular, the shielding unit could absorb and / or reflect to a large or complete extent the light emitted by the first light element.

In this way, particularly advantageous lighting can be achieved and / or effects of unwanted interference between two luminous elements directly adjacent to each other can be prevented.
    When viewed perpendicularly on the main extension plane of the cooking field plate, the shielding unit could be arranged, for example, exclusively between the two luminous elements directly adjacent to each other, the luminous elements being, in particular, all the elements luminous, of the lighting unit, arranged in a row. However, preferably, when viewed perpendicularly on the main extension plane of the cooking field plate, the shielding unit surrounds at least one of the luminous elements through an angular area of at least 180 °, so preferably, at least 270 °, advantageously, at least 300 °, particularly advantageously, at least 330 ° and, preferably, at least 350 °, with respect to the central point and / or center of gravity of the light element.

The shielding unit has an essentially grid-shaped conformation, and is made as a grid-shaped building unit. The distances between the central points of the grid cells of the essentially grid-shaped conformation of the shielding unit correspond to the distances between the central points of the luminous elements. In this way, interference between the luminous elements in a directed and / or lasting manner can be prevented, thereby making optimum illumination possible.
    Likewise, it is proposed that the shielding unit has a distance of a maximum of 20 mm, preferably, a maximum of 15 mm, advantageously, a maximum of 12 mm, particularly advantageously, a maximum of 10 mm and, preferably, 8 mm maximum, with respect to the luminous elements. By way of example, the shielding unit could be partially or completely arranged in a plane laid out by the luminous elements and have a distance with respect to them of approximately or exactly 0 mm in the vertical direction. Advantageously, the unit
    The shield is arranged distanced from the luminous elements in the vertical direction.

    Advantageously, the shielding unit has a distance, which is measured in parallel to the vertical direction, of at least 0.2 mm, preferably, at least 0.5 mm, advantageously, of at least 1 mm and, preferably, at least 2 mm, with respect to the luminous elements. Thus, a compact embodiment can be achieved with optimal illumination at the same time. In particular, cooling of the light elements for a distance greater than zero becomes possible.
    In addition, it is proposed that the lighting unit has at least one diffusion unit, which disperses the light emitted in the operating state by the luminous elements before it reaches the partial surface area. In the installation position, the diffusion unit is arranged at least in large part and, advantageously, completely, between the luminous elements and the partial surface area. The term "broadcast unit" includes the concept of a unit that is intended to transmit a percentage of at least 75%, preferably at least 80%, advantageously, at least 85%, of particularly advantageous, of at least 90% and, preferably, of at least 95% of the incident light on a first side to a second side, opposite the first side, and to modify the direction of this percentage of the In particular, the diffusion unit is intended to transmit a maximum percentage of 10%, preferably, maximum 8%, advantageously, maximum 5%, particularly advantageously, 3% as maximum and, preferably, a maximum of 1% of the incident light on a first side to a second side, opposite to the first side, and to allow this percentage of the light to pass without modifying. roughly or exactly shaped plate, so that the diffusion unit can be manufactured in a particularly simple and / or economical manner and / or so that a particularly compact embodiment can be achieved. In addition, the diffusion unit has at least one longitudinal extension and at least one transverse extension, oriented perpendicular to the longitudinal extension, which are considerably greater than the thickness of the diffusion unit. The longitudinal extension of the diffusion unit and, in addition, the transverse extension of the diffusion unit, are oriented parallel to the main extension plane of the diffusion unit. As an example, the diffusion unit could be composed largely or entirely of glass and / or glass ceramic and / or plastic and / or silicone. When viewed perpendicularly on the main extension plane of the cooking field plate, the diffusion unit could extend over essentially the entire extension of the cooking field plate.

    The diffusion unit could be limited to particular areas, such as the extension of the luminous elements of the lighting unit, where the diffusion unit could have for each luminous element at least a partial area assigned to the luminous element. As an example, the diffusion unit and the armor unit could be made in one piece. The diffusion unit and the armor unit are made in each case as separate and / or autonomous construction units. The expression "in one piece" includes the concept of joining at least in union of material, by way of example, by means of a direct welding process, a bonding process, an injection process on top and / or another process that is appropriate to the skilled in the art, and / or, advantageously, formed into a piece such as, for example, by manufacturing from a cast piece and / or by manufacturing it in an injection procedure of one or more components and, of advantageously, from a single blank, in this way, punctual illumination can be avoided and / or uniform illumination and / or by a large surface area can be achieved, in particular, uniform light scattering is possible provided by the luminous elements, so that a user-friendly display can be achieved.
    Likewise, it is proposed that the diffusion unit disperse the light emitted by the luminous elements through a solid angle of at least n, preferably, of at least 3n / 2 and, advantageously, of at least 2n, with with respect to at least one point on a surface of the diffusion unit directed towards the partial surface area at least in the assembled state. In the operating state, the diffusion unit disperses the light emitted by the luminous element in approximately or exactly a whole hemisphere directed towards the partial surface area with respect to at least any point on a surface of the diffusion unit directed towards the partial surface area at least in the assembled state. In this way, a particularly diffused and well distributed light can be provided, thus achieving uniform illumination.
    The diffusion unit could be arranged, for example, under the cooking field plate in the installation position. By way of example, the cooking field device could have at least one support unit for fixing the diffusion unit, which could directly and / or indirectly set the position and / or location of the diffusion unit in a relative manner. to the cooking field plate. Preferably, the diffusion unit is joined in one piece with the cooking field plate. The cooking field plate could be treated in the area that is made in one piece with the diffusion unit, and the optical properties of the cooking field plate could be
    modified in the area. The cooking field plate could be treated in the area

    35
    by laser and / or by at least one corrosive fluid and / or by at least one dispersive fluid. In this way, great stability is achieved.
    The diffusion unit could be made, for example, separated from the cooking field plate and fixed thereto by means of a material joint, for example, by a bonding joint, at least in the assembled state. Preferably, the diffusion unit is made in one piece with the cooking field plate, so that reduced storage is possible and / or the amount of construction units is small.
    In addition, it is proposed that the cooking field device has at least one cooling channel unit in which the lighting unit is partially or completely arranged. At least the luminous elements of the lighting unit are arranged at least in large part and, advantageously, completely, in the cooling channel unit. The term "cooling channel unit" includes the concept of an area, in particular, a volumetric area, which is intended to cool at least one object that could be part of the cooking field device. The object is the unit of lighting The cooling channel unit is provided at least to evacuate the heat generated during a cooking process from the lighting unit, and is arranged between the cooking field plate and at least one heating element. preferably, the cooling channel unit has a horizontal surface extension parallel to the main extension plane of the cooking field plate, which corresponds to at least 30%, preferably at least 50%, so preferred, at least 70% or, particularly preferably, at least 90% of the surface extension of the cooking field plate parallel to the main extension plane of the camp plate or cooking.The cooling channel unit is filled with at least a large part of a refrigerant. Preferably, the refrigerant is composed at least partially and, preferably, completely, by a gaseous medium, preferably air. As an example, the cooling channel unit could be divided in the horizontal plane into at least two partial cooling channels. In this way, cooling to one area and / or several areas, arranged one behind the other in the direction of the refrigerant flow, which are hot during operation can be advantageously limited. Alternatively or additionally, the cooling channel unit could have at least one opening, which may be provided for outside air to be supplied to the intermediate space and / or to be expelled from the intermediate space. In this way, outside air can be advantageously used as
    refrigerant. Preferably, the cooking field device has a unit

    circulation, which is intended to circulate the refrigerant. When circulating, the refrigerant flows along the flow direction. Preferably, the flow direction is essentially parallel to the main extension plane of the cooking field plate. The circulation unit is preferably made as a fan, more preferably, as a transverse current blower. The expression that a construction unit is "partially or completely arranged in the cooling channel unit" includes the concept that, at least in the assembled state, at least 5%, preferably at least 15%, more preferably, at least 30% or, particularly preferably, at least 50% of the volume of the construction unit is in the volume formed by the cooling channel unit. overheating, so that a lasting realization can be achieved.
    Likewise, it is proposed that the diffusion unit conforms to the cooling channel unit partially or completely. The expression that the diffusion unit "conforms" the cooling channel unit "partially or completely" includes the concept that a delimitation of the cooling channel unit on at least one side, namely the side upper, be made by the diffusion unit at least 50%, preferably at least 75% or, more preferably, at least 90%. Alternatively, it is conceived that the cooling channel unit is thermally decoupled from the broadcast unit, for example, through an intermediate space evacuated between the broadcast unit and the cooling channel unit. In this way, a compact construction of the cooling channel unit can be achieved. Despite the diffusion unit, cooling is possible. Furthermore, it is possible to advantageously dispense with additional parts that make up the cooling channel unit, whereby the production costs can be advantageously low. Furthermore, in this way, it is advantageously possible for the cooking field plate to cool rapidly after finishing a cooking process, thus improving the safety of operation and / or thus making possible a rapid cooking process.
    In addition, it is proposed that the diffusion unit partially or completely conform one side of the cooling channel unit directed towards the partial surface area, thereby preventing the cooling of the cooking field plate, thereby advantageously attenuating the heat evacuation of the diffusion unit and, indirectly, of the cooking battery that is resting on it.
    Likewise, it is proposed that two luminous elements directly adjacent to each other in the direction present in the direction a distance between their central points of 20 mm as

Alternatively or additionally, two luminous elements directly adjacent to each other in the direction could have in the direction a distance between their central points of a maximum of 10 mm, preferably, a maximum of 9 mm, advantageously, of 8 mm maximum, particularly advantageously, maximum 7 mm and, preferably, maximum 6 mm. Thus, a compact embodiment can be achieved. In addition, a great diversity in the freedom of configuration is possible, since a large number of different shapes and / or configurations and / or information can be implemented through the lighting unit.
    In addition, it is proposed that the lighting unit has an amount of at least 100, preferably, at least 200, advantageously, at least 300 and, preferably, at least 400 light elements. Alternatively or additionally, the lighting unit could have an amount of at least 1,000, preferably, at least 2,000, advantageously, at least 3,000 and, preferably, at least 4,000 light elements. Likewise, the lighting unit has a maximum amount of 10,000, preferably a maximum of 8,000, advantageously, a maximum of 7,000 and, preferably, a maximum of 6,000 light elements. Alternatively or additionally, the lighting unit could have an amount of at most 1,000, preferably at most 800, advantageously at most 700 and, preferably, at most 600 light elements.
