Description
[0001] The invention relates to a hob device according to the preamble of claim 1.
[0002] A hob device is already known from the prior art in which a plurality of heating elements are arranged in an installation position below a hob plate. An electronics unit is arranged vertically below the heating elements and is located in the immediate vicinity of the heating elements to supply them. The heating elements and the electronics unit are arranged within a storage space partially enclosed by an outer housing unit. An extraction unit has a fan wheel and, by means of the fan wheel, extracts vapors generated during operation from a cooking chamber above the hob plate. The fan wheel is arranged in an installation position below a base housing section of the outer housing unit and is thus vertically below both the heating elements and the electronics unit.The vapors generated during operation and extracted from the cooking chamber by the fan wheel first pass vertically through the outer housing unit and are then redirected by the fan wheel. In this embodiment, the electronics unit is located in a temperature-critical area due to its proximity to the heating elements, which creates the risk of overheating. With this arrangement, the use of the extraction unit is limited to large cooktops, which, in particular when viewed perpendicular to a main extension plane of the cooktop plate, have dimensions of at least 90 cm. Document WO 2017 / 029128 A1 discloses a device largely according to the preamble of claim 1, but without a circuit board. which is converted into heat by eddy current induction and / or magnetization reversal effects. In one installed position, the heating element is arranged in particular below the cooktop plate.Advantageously, the heating element is arranged in an installation position in a close area of the hob plate.

It is proposed that the fan wheel is arranged in an installed position in a vertical direction between the electronics unit and the heating element. Such a configuration can in particular achieve an improved and / or optimized design. The electronics unit can in particular be arranged at a sufficiently large distance from the heating element and thus in an area in which reaching critical temperatures can be avoided.In particular, a previously novel design can be created, particularly when compared with products from competitors and / or rivals. The extraction unit can be used in particular for smaller cooktops, which, in particular when viewed perpendicularly to a main extension plane of a cooktop plate, have a dimension of essentially 60 cm, and in particular while maintaining an extraction performance compared to designs known from the prior art. In particular, an interruption of the electronics unit and / or a storage space defined by an outer housing unit can be avoided, which in particular makes a large-area electronics unit possible.The electronic unit can advantageously be arranged outside an exhaust duct through which the vapors generated in the operating state flow, which in particular enables a safe arrangement of the electronic unit.

Advantageously, the heating element is arranged, in one installation position, in a close vicinity of the cooktop plate.
[0007] An "extraction unit" is understood to mean, in particular, a unit designed to extract and / or filter vapors generated by the fan wheel in at least one operating state, and in particular to at least transport these vapors away from a cooking area by means of the fan wheel.

In particular, the extraction unit comprises at least one air guide unit, which defines, in particular, at least one extraction duct and is designed, in particular, to connect the cooking chamber to the fan wheel by means of the extraction duct. In particular, the extraction duct is designed to conduct the vapors generated in the operating state.
[0008] A "fan wheel" is understood, in particular, to mean a unit designed to provide at least one intake stream for vapors generated in the operating state, and in particular to at least transport the extracted vapors from the cooking area. For example, the extraction unit could be designed to extract the vapors generated in the operating state from the cooking area and additionally from a cooking chamber by means of the fan wheel, and to feed them, for example, to at least one exhaust air duct. Alternatively, the extraction unit could be designed, in particular, to transport the vapors generated in the operating state from the cooking area to at least one further sub-area of the cooking chamber by means of the fan wheel.A "cooking area" is understood, in particular, to be a sub-area of a cooking chamber in which, in the operating state, a cooking process takes place and in which, in particular, vapors generated during the cooking process escape from at least one heated cooking utensil. This sub-area advantageously extends, in an installed position, at least largely above the cooktop plate. A "cooking chamber" is understood, in particular, to be a space in which a cooktop comprising the cooktop device is installed and / or arranged.
[0009] An "electronic unit" is understood, in particular, to mean an electrical and / or electronic unit comprising at least one electrical and / or electronic component, preferably designed as a power component. The electronic unit comprises at least one printed circuit board and, in particular, additionally at least one component, which is arranged on the printed circuit board, in particular at least in an assembled state. The component could, for example, be at least one inverter and / or at least one control unit and / or at least one cooling unit. In particular, the electronic unit is provided at least to supply the heating element, in particular with electrical energy.
[0010] In an installed position, the vertical direction is oriented, in particular, perpendicular to a main extension plane of the electronics unit and / or to a main extension plane of the cooktop panel. A "main extension plane" of an object is understood, in particular, to be a plane that is parallel to a largest side surface of a smallest imaginary geometric cuboid that just completely encloses the object, and in particular, runs through the center of the cuboid.
[0011] When viewed in a direction parallel to a main extension plane of the electronics unit and / or to a main extension plane of the hob plate, the heating element and the electronics unit are arranged, in particular, on opposite sides of the fan wheel. In particular, in at least one assembled state, the fan wheel is spaced from the hob plate at a distance that is, in particular, greater than the distance between the heating element and the hob plate and, in particular, smaller than the distance between the electronics unit and the hob plate.
[0012] "Intended" should be understood in particular to mean specifically programmed, designed, and / or equipped. The fact that an object is intended for a specific function should be understood in particular to mean that the object fulfills and / or performs this specific function in at least one application and / or operating state.
[0013] For example, the heating element and the fan wheel could be arranged next to one another and, in particular, without overlapping when viewed perpendicularly to a main extension plane of the electronics unit. For example, the heating element and the electronics unit could be arranged next to one another and, in particular, without overlapping when viewed perpendicularly to a main extension plane of the electronics unit. In particular, the heating element and the fan wheel could be arranged next to one another in a horizontal direction. In particular, the heating element and the electronics unit could be arranged next to one another in a horizontal direction. The horizontal direction could, in particular, be oriented perpendicular to the vertical direction and, in particular, parallel to a main extension plane of the electronics unit and / or to a main extension plane of the hob plate.The impeller is arranged at least partially and in particular completely overlapping with the electronics unit when viewed perpendicularly to a main extension plane of the electronics unit. The phrase "a first object is arranged at least "partially" overlapping with a second object when viewed perpendicularly to a main extension plane of the electronics unit" is to be understood in particular as meaning that the first object, when viewed perpendicularly to a main extension plane of the electronics unit, is arranged so as to overlap a surface of the second object by an area proportion of at least 20%, in particular of at least 40%, advantageously of at least 60%, particularly advantageously of at least 80%, and preferably of at least 90% of a surface of the first object.The heating element is arranged at least partially and in particular completely overlapping with the electronics unit, particularly when viewed perpendicularly to a main extension plane of the electronics unit. The impeller could be arranged at least partially overlapping and in particular at least partially non-overlapping with the heating element, particularly when viewed perpendicularly to a main extension plane of the electronics unit. Alternatively or additionally, the impeller could be arranged at least partially and in particular completely overlapping with the electronics unit, particularly when viewed perpendicularly to a main extension plane of the electronics unit. This makes it possible, in particular, to achieve optimal space utilization and / or a compact design.
[0014] It is also proposed that the extraction unit have at least one air guiding unit, which is intended to keep at least the vapors away from the electronics unit. The air guiding unit has, in particular, at least one partial region which is arranged in an installed position between the impeller and the electronics unit. For example, the air guiding unit could be at least substantially plate-shaped and, in particular, be arranged in an installed position below the impeller. Advantageously, the air guiding unit surrounds the impeller in at least one installed state with respect to a center point and / or center of gravity of the impeller over an angular range of at least 90°, in particular of at least 180°, advantageously of at least 270°, particularly advantageously of at least 300° and preferably of 330°.In particular, the air guide unit is designed to shield the electronics unit from the impeller in at least one operating state. The air guide unit is designed, in particular, to at least substantially shield the electronics unit from fluids coming from the impeller in at least one operating state and, in particular, to keep these fluids away from the electronics unit. The fluids coming from the impeller could, in particular, be liquids dripping from the impeller, such as oil and / or water and / or vapors. This can, in particular, prevent premature failure and / or damage to the electronics unit, thereby achieving a long-lasting design.
[0015] It is further proposed that the air guiding unit be designed to divert the vapors into at least one external area. An "external area" is to be understood, in particular, as an area which, in at least one assembled state, is arranged outside the outer housing unit. In particular, the air guiding unit defines and / or delimits at least one exhaust air duct, which, in particular, connects the impeller to the external area and which, in particular, in at least one operating state, is designed to guide the vapors from the impeller to the external area, in particular due to the kinetic energy supplied to the vapors by the impeller. This allows the vapors to be removed in a targeted manner, thereby achieving, in particular, a high level of operator comfort.
[0016] In an installed position, the outer area could, in particular, be a lateral area of the outer housing unit. Alternatively or additionally, in an installed position, the outer area could, in particular, be a front area, which could, in particular, be arranged facing an operator. Preferably, in an installed position, the outer area is a rear area, which, in particular, is arranged facing away from an operator. This allows the vapors to be kept away from an operator, in particular, thereby enabling comfortable operation and / or cooking.
[0017] It is also proposed that the cooktop device comprise at least one outer housing unit, which at least largely surrounds the air guide unit. An "outer housing unit" is understood, in particular, to mean a unit which, in at least one assembled state, is arranged facing and / or accessible to an operator and which, in particular in the assembled state, is connected to the cooktop plate and, in particular, with the cooktop plate, at least largely delimits and / or defines a storage space, which could, in particular, define an interior of the appliance.The phrase that the outer housing unit surrounds the air guiding unit at least "to a large extent" is to be understood in particular as meaning that the outer housing unit surrounds the air guiding unit with respect to a center point and / or center of gravity of the air guiding unit in at least one plane, which can be selected arbitrarily and is advantageously aligned at least substantially parallel to a main extension plane of the electronics unit and / or to a main extension plane of the cooktop plate, over an angular range of at least 270°, in particular of at least 300°, advantageously of at least 320°, particularly advantageously of at least 340°, and preferably of 350°. In at least one assembled state, the air guiding unit is arranged in particular within the storage space.This makes it possible, in particular, to achieve a protected arrangement of the air guiding unit and / or the impeller, which in particular makes it possible to achieve a long-lasting design.
[0018] It is further proposed that the cooktop device comprise at least one outer housing unit, which comprises at least one base housing part, by which the electronics unit is supported. A "base housing part" is to be understood, in particular, as an element which, in an installed position, forms a lowermost boundary of at least one storage space at least partially bounded by the outer housing unit and / or which, when viewed perpendicular to at least one main extension plane of the outer housing unit and / or to at least one main extension plane of the electronics unit, extends over a surface area of at least 50%, in particular of at least 60%, advantageously of at least 70%, particularly advantageously of at least 80%, and preferably of at least 90% of a total surface area of the outer housing unit. In an installed position, the electronics unit rests, in particular, at least partially, on the base housing part.In one installed position, the base housing part in particular absorbs at least a large part of the weight of the electronics unit and transmits the absorbed weight in particular to at least one further unit, such as in particular the hob plate. In at least one assembled state, the electronics unit extends in particular over a surface area of at least 50%, in particular of at least 60%, advantageously of at least 70%, particularly advantageously of at least 80% and preferably of at least 90% of a total surface area of the base housing part and / or over an area of at least 1800 cm 2< , in particular of at least 2150 cm 2< , advantageously of at least 2500 cm 2< , particularly advantageously of at least 2750 cm 2< and preferably of at least 3000 cm 2< . This makes it possible in particular to design the electronics unit over a large area and / or to arrange it securely.
[0019] It is further proposed that, in an installed position, a particularly minimum distance between the impeller and the heating element in the vertical direction is a maximum of 70 mm, in particular a maximum of 60 mm, advantageously a maximum of 50 mm, particularly advantageously a maximum of 45 mm, and preferably a maximum of 40 mm. In particular, a particularly minimum distance between the impeller and the heating element in the vertical direction is at least 5 mm, in particular at least 10 mm, advantageously at least 15 mm, particularly advantageously at least 20 mm, and preferably at least 25 mm. This makes it possible, in particular, to achieve a compact design.
[0020] In addition, it is proposed that in an installed position, a particularly smallest distance between the electronics unit and the heating element in the vertical direction is at least 70 mm, in particular at least 85 mm, advantageously at least 100 mm, particularly advantageously at least 120 mm and preferably at least 130 mm. In particular, a particularly smallest distance between the electronics unit and the heating element in the vertical direction is a maximum of 180 mm, in particular a maximum of 200 mm, advantageously a maximum of 210 mm, particularly advantageously a maximum of 220 mm and preferably a maximum of 230 mm. This makes it possible, in particular, to spatially separate the electronics unit from the heating element, whereby the electronics unit can be arranged in a region in which reaching critical temperatures can be avoided.
[0021] It is further proposed that the cooktop device comprise at least one cooktop plate, which has at least one extraction recess provided for the passage of vapors. An "extraction recess" is to be understood in particular as an opening and / or a hole in the cooktop plate through which the fan wheel extracts the vapors from the cooking chamber in at least one operating state. In particular, the air guiding unit defines and / or delimits at least one extraction duct, which, in at least one assembled state, connects the extraction recess and the fan wheel. The air guiding unit is particularly intended to connect the cooking chamber to the fan wheel by means of the extraction duct. In particular, the extraction duct is provided for conducting the vapors generated in the operating state. This makes it possible, in particular, to achieve a compact design.
[0022] It is further proposed that the fan wheel be arranged at least partially overlapping the extraction recess when viewed perpendicularly to a main extension plane of the cooktop plate. The phrase "the fan wheel is arranged at least "partially" overlapping the extraction recess when viewed perpendicularly to a main extension plane of the cooktop plate" is to be understood in particular as meaning that the fan wheel, when viewed perpendicularly to a main extension plane of the cooktop plate, is arranged to overlap the extraction recess to an area proportion of at least 50%, in particular at least 60%, advantageously at least 70%, particularly advantageously at least 80%, and preferably at least 90% of a total area of the fan wheel and / or the extraction recess. In an installed position, the fan wheel is arranged at least partially below the extraction recess, in particular in the vertical direction.This makes it possible, in particular, to achieve simple extraction of the vapors, since a short path is provided between the extraction recess and the fan wheel, thus enabling the vapors to travel a short distance.
[0023] For example, the extraction unit could comprise exclusively the fan wheel. Preferably, the extraction unit comprises at least one further fan wheel, which is intended to at least partially extract vapors generated from the cooking area in at least one operating state and which is arranged in an installed position in the vertical direction between the electronics unit and the heating element. As a result, the vapors can be extracted from the cooking area particularly quickly, since in particular a high driving force for extraction can be provided. Particularly advantageously, if one of the fan wheels fails, in particular another of the fan wheels can maintain cooking operation, thereby making it possible to achieve a low probability of a complete failure of the extraction unit.In particular, instead of a single, very expensive and high-quality impeller, two comparatively cheaper impellers can be used, which allows particularly low costs to be achieved.
[0024] The impeller and the additional impeller could, for example, be arranged at least partially overlapping the extraction recess when viewed perpendicularly to a main extension plane of the cooktop plate. Alternatively or additionally, the impeller and the additional impeller could be arranged on a single side of the extraction recess, in particular when viewed perpendicularly to a main extension plane of the cooktop plate. Preferably, the impeller and the additional impeller are arranged on opposite sides of the extraction recess when viewed perpendicularly to a main extension plane of the cooktop plate. This makes it possible, in particular, to dispense with the need for an impeller directly below the extraction recess, which, in particular in at least one operating state, enables low noise and comfortable working for the operator, in particular while avoiding noise pollution.
[0025] It is further proposed that the extractor unit comprise at least one grease filter unit, which, particularly in an installed position, has a minimum distance from a top edge of the hob plate of a maximum of 70 mm, in particular a maximum of 50 mm, advantageously a maximum of 40 mm, particularly advantageously a maximum of 30 mm, preferably a maximum of 20 mm, and particularly preferably a maximum of 10 mm. This allows for a particularly compact design.
[0026] The hob device is not intended to be limited to the application and embodiment described above. In particular, the hob device may have a number of individual elements, components, and units that differs from the number stated herein to fulfill a functionality described herein.

In one installed position, the impeller 16a is arranged above the electronics unit 20a in the vertical direction 22a. An air guide unit 24a is arranged between the electronics unit 20a and the impeller 16a in one installed position in the vertical direction 22a.
[0051] The extractor unit 14a includes the air guide unit 24a. In an operating state, the air guide unit 24a keeps the vapors generated during the operating state away from the electronics unit 20a. In an assembled state, the air guide unit 24a essentially completely surrounds the fan wheel 16a with respect to a center point and / or center of gravity of the fan wheel 16a, viewed in a plane that is aligned, in particular, parallel to a main extension plane of the cooktop plate 36a.
