Description

Technical Field

[0001] The invention relates to a cooker having an integrated exhaust device and lighting device according to the preamble of claim 1. The invention also relates to the use of a cooker according to claim 13 for lighting. Background Art

[0002] A common cooker comprises a cooker panel which is generally rectangular and has rounded outer edges. One or more heating units are arranged below the cooker panel; for example, a radiant heating unit or an induction heating coil may be provided against the bottom side of the cooker panel. Furthermore, a cooker housing (including a cooker control and a power supply for the cooker control and the heating unit) is located below or against the bottom side of the cooker panel. As is known, the cooker housing may also advantageously contain the heating unit or cover it at the bottom. A frame may preferably be arranged circumferentially at the outer edge of the cooker panel, which frame is designed to be connected to the countertop when the cooker is located at or in the countertop.

[0003] Cooktops of these types are known in many embodiments in the prior art.

[0004] For example, a cooktop having at least one temperature sensor is known from DE 10 2019 123 703 A1.

[0005] DE 10 2020 212 171 A1 relates to a cooktop having a weight sensor.

[0006] A sensor-controlled cooktop with a vibration sensor is known from DE 20 2005 015 553 U1.

[0007] DE 10 2019 107 558 A1 relates to a method for operating a cooking zone of a cooker (preferably an induction cooker) for processing cookware.

[0008] A cooker and a method for controlling the energy supply of a heating element of a cooker are known from DE 10 2010 064 294 A1.

[0009] According to DE102004011749A1, a cooker with multiple cooking zones and associated heating elements is designed so that an associated cooking vessel recognition sensor (e.g., inductive or capacitive) can recognize a touch of a finger or similar object on a placed cooking vessel, which the cooker controller sees as the selection of the associated cooking zone.

[0010] A cooking surface with a downdraft exhaust hood is known from DE 202019106084 U1, which has a top side and a bottom side and comprises the following items: a plurality of cooking zones located near the surface, and an intake duct extending between the top side and the bottom side in a predetermined extension direction, wherein the intake duct has an intake opening near the top side and is in fluid connection with the outer area. The cooking surface also includes a device, which together with the surface forms a mounting unit for the cooking surface, so as to provide the mounting unit and discharge cooking steam downwards.

[0011] DE1579679A1 discloses a device for discharging steam and fumes generated during cooking from a stove by means of a suction fan.

[0012] From EP 3 869 107 A1 a mounting unit is known which comprises a cooker and means for operating the cooker and for venting cooking steam downwards.

[0013] A cooker with a cooker panel and a light source below it can be known from DE10020208221A1, and the light source is activated differently. For this purpose, a light source irradiated from the cooker is provided, which irradiates, emits light or illuminates through the cooker panel or through the side of the cooker panel.

[0014] One disadvantage is that the light output of the light source radiating from the cooktop is relatively high. In addition, power loss of the light source is caused by the glass ceramic panel. In addition, there are aesthetic disadvantages because the glass ceramic plate of the cooktop requires transillumination, which inadvertently changes the color of the required light.

[0015] Light sources known from the prior art, which are located at the sides of the glass ceramic panel, are not suitable for uniform illumination of the area above the cooktop panel, since they only shine through the cooktop panel, in particular horizontally or at a flat angle. Summary of the invention

[0016] Starting from the above-mentioned disadvantages, the object of the present invention is to provide a cooker panel with integrated ventilation which is energy-optimized and has an aesthetically pleasing lighting.

[0017] This object is achieved by a cooker panel with integrated exhaust gas and lighting according to claim 1. The object is further achieved by the use of a cooker according to claim 13 .

[0018] The invention relates to a cooker with integrated lighting, comprising a cooker panel, in particular a glass ceramic panel, having at least one cooking zone and having a top side on which cookware can be placed and a bottom side facing away from the top side.

[0019] Furthermore, the cooktop has at least one heating unit, in particular an induction coil, beneath the cooktop panel for heating the cookware.

[0020] At least one suction opening of the suction duct is also provided, which is arranged substantially in the plane of the surface of the cooker panel for drawing cooking steam or cooking fumes downwards and transferring them under the cooker panel.

[0021] At least one light source is used to illuminate from the cooktop to achieve integrated lighting.

[0022] According to the invention, the at least one light source is located substantially inside the at least one intake duct or intake opening.

[0023] The lighting source can serve as ambient lighting to illuminate the space. The brightness and / or color can be changed by the fan level.

[0024] For example, the lighting source can also have functions such as residual heat display. The brightness or color of the light can change according to the temperature.

[0025] The lighting source can also provide a notification function, such as flashing when a cooking zone timer or egg timer has ended, in addition to or instead of the audible signal.

[0026] Furthermore, the lighting source can provide a warning signal if at least one cooking zone is switched on but no further operation is performed after a defined period of time has elapsed. This can, for example, serve as a "no-answer switch" to warn elderly or forgetful people that a cooking process has started before the cooktop is completely switched off.

[0027] The cooker is preferably designed as an induction cooker, since it can be adjusted very finely and directly. However, the invention also includes embodiments using other heating technologies.

[0028] According to a first advantageous embodiment of the invention, the at least one light source radiates light from the intake duct of the cooker via an optical fiber, and in particular, the at least one light source is laterally located inside or at the bottom of the intake duct or the intake opening for indirect lighting.

[0029] The light source can be located laterally inside or at the bottom to illuminate at an angle from the ventilation duct, or it can be illuminated indirectly.

[0030] Another advantageous variant of the invention provides that the light source comprises an LED or consists of an LED or an LED strip.

[0031] In an advantageous development of the invention, the at least one light source is activatable by means of a light controller, wherein a communication device is preferably connected to the light controller and is designed for communication with an external control device / receiver, preferably wirelessly via WLAN, Bluetooth or the like.

[0032] The light controller is designed to activate the light source to shine from the cooker upon receipt of the control signal by the communication device, thereby creating ambient or background lighting in the space surrounding the cooker.

[0033] According to a further advantageous embodiment of the invention, the light controller is connected to a control and / or regulation device for controlling and / or regulating the energy of a heating unit of the cooker for bidirectional transmission of data.

[0034] Another advantageous embodiment of the invention provides that at least one light source is operable via a control element, in particular an operating sensor, which is located below the cooktop and is preferably designed as a capacitive sensor for operation on the surface of the cooktop.

[0035] It can also be provided that the brightness and / or the color of the light of the at least one light source is adjustable, in particular that the color of the light is automatically adjustable, for example as a function of the ambient noise.

[0036] Regarding the installation or arrangement of the light source for a cooker according to the present invention, the basic and preferred aspects of the present invention can be summarized as follows:

[0037] The illumination source (light source) is installed in the ventilation duct and shines directly into the space through the ventilation openings, rather than through the glass ceramic surface. The advantage of this is that the color of the light is not distorted by the filtering effect of the glass ceramic surface, or that it is not necessary to use a specific glass ceramic glass that does not have this filtering effect. In addition, the light intensity is affected by the glass ceramic surface.

[0038] The illumination source may consist of one or more light sources.

[0039] The light source preferably consists of a single LED or a LED strip.

[0040] The light source shines directly into the ventilation duct without the need to guide the light through optical fibers.

[0041] For contact protection and easy cleaning, the light source may be protected by a transparent cover (eg glass or plastic).

[0042] The light source may be mounted directly below the cooktop surface, or may be mounted below one or more walls or at the bottom of a ventilation duct.

[0043] Also advantageous is an embodiment according to the invention in which the at least one intake opening is located in a plane parallel to the surface of the top side of the cooktop panel.

[0044] In an advantageous embodiment of the invention, it is provided that at least one intake opening is slot-shaped, in particular designed in the form of a gap or an outflow channel, wherein adjacent slot-shaped intake openings are preferably positioned approximately perpendicularly to one another.

[0045] According to a further advantageous embodiment of the invention, the at least one intake opening is located approximately in the center of the cooktop.

[0046] A further advantageous embodiment of the invention provides that the at least one intake opening is fluidically connected to a suction chamber which has a rotating impeller of a fan motor for exhausting the cooking vapors or cooking fumes.

[0047] It is also advantageous if, according to an embodiment of the invention, a sensor system comprising at least one sensor is provided for measuring temperature and / or for measuring movement / vibration and / or for measuring weight, and in particular the sensor system is connected to a control and / or regulating device for signal transmission.

[0048] The sensor system can be located under the cooktop, preferably between the bottom side of the cooktop and the heating unit and / or on the side of the heating unit. Therefore, the installation space can be optimally utilized. The lateral arrangement reduces the influence of the alternating magnetic field induction cooktop on the sensor.

[0049] The sensor system may comprise at least one temperature sensor for determining the temperature directly below the cooktop, in particular on the underside of the cooktop, and / or at least one infrared sensor for determining the cooktop base temperature through the cooktop, in particular a glass ceramic panel.

[0050] The energy for heating the heating unit of the cooker which is necessary for the desired cooking process can be determined in the control and / or regulating device as a function of the determined cooktop temperature and / or the determined cooking food temperature.

[0051] By using at least one heating unit activated by the control and / or regulating device, the energy required for the desired cooking process is automatically delivered to the cooktop.

[0052] It is particularly advantageous if the processing and evaluation of the sensor signals of the sensor system takes place in the electronic system or control and / or regulation unit of the cooktop, which then controls the cooking zone accordingly. Induction cooktops may include a cooktop container recognition; without this recognition, the power supply is not switched on and no heating operation takes place.

[0053] To improve accuracy, each sensor can also be present in multiple quantities.

[0054] An independent concept of the present invention relates to the use of the above-mentioned cooker to illuminate the space where the cooker is located by means of at least one light source located in the cooker.

[0055] Further objects, advantages, features and application options of the invention are derived from the following description of an exemplary embodiment with reference to the accompanying drawings. All features described and / or shown in the drawings constitute the subject matter of the invention individually or in any meaningful combination and independently of their grouping in the claims or their reference.

[0065] Figure 1 A cooktop 10 is shown in a perspective view from above, wherein the cooktop panel 1 is designed in the present example as a glass ceramic panel 1 and has four cooking zones 14 in the exemplary embodiment selected.

[0066] Cookware (not shown) can be placed on the top side 1 of the cooktop panel 2. The cooking zone 14 in this example is provided with markings 7 on the top side 2 of the glass ceramic glass plate 1 (see Figure 1 and Figure 6 The cooktop panel 1 has a bottom side 3 facing away from the top side 2 .

[0067] Figure 2 The cooktop 10 is shown in a further perspective view, also from above.

[0068] Figure 3 Shown according to Figure 1 and Figure 2 However, for greater clarity, the cover grille 32 of the suction opening 30 for the suction duct 31 is shown in FIG. Figure 3 is hidden in.

[0069] Figure 4 yes Figures 1 to 3 FIG. 1 is a top view of the cooker 10 in FIG. 1 .

[0070] Figure 5 Shown according to Figures 1 to 4 However, for better understanding, the cooker panel 1 has been hidden so that the components located under the cooker panel 1 can be clearly understood.

[0071] from Figure 5 It can be clearly seen that at least one heating unit is located under the cooker panel 1 for heating the cooker, which is designed as an induction coil 4 in this example. The control and / or regulation device 6 is provided with energy for controlling and / or regulating the heating unit 4. Figure 5 Furthermore, a cooktop 10 is shown with four cooking zones 14. Also evident is a control unit 8 for controlling and / or regulating the device 6.

[0072] It is also obvious that Figure 5 As shown, the sensor system 5 has at least one sensor for measuring temperature and / or for measuring movement / vibration and / or for measuring weight. The sensor system 5 is connected to a control and / or regulating device 6 for signal transmission.

[0073] The cooker 10 , in particular the cooker panel 1 , may have a function button, shown at position 9 , for activating, switching and deactivating a lighting function, so as to change between the lighting function and conventional operation with the lighting function deactivated upon actuation.

[0074] Figures 1 to 5 Also shown is an intake opening 30, which is arranged substantially in the plane of the surface of the cooktop panel 1 for drawing cooking steam or cooking fumes downwards and passing them under the cooktop panel 1. In this example, the intake opening 30 is located in a plane parallel to the surface of the top side 2 of the cooktop panel 1. The intake opening 30 is part of the intake duct 31, which can be closed by a cover grille 32 (see FIG. Figure 1 and Figure 2 ).

[0075] The suction opening 30 shown in the exemplary embodiment is slot-shaped, in particular designed in the form of a gap or outflow channel. A plurality of suction openings can also be envisaged, wherein adjacent slot-shaped suction openings 30 can be positioned approximately perpendicularly to each other.

[0076] In this example, the suction opening 30 is located approximately in the center of the cooker 10 and extends along the width of the cooker panel 1 .

[0077] The suction opening 30 is fluidly connected to a suction chamber which has a rotating impeller (fan motor) for exhausting cooking steam or cooking fumes downwards. Figures 1 to 5 In the variant embodiment of the present invention, the fan housing 13 for accommodating the fan motor can be clearly seen. The housing 13 is located at the subframe 15 of the cooker 10 below the cooker panel 1.

[0078] also, Figures 1 to 5 A plurality of light sources 40 are shown radiating from the cooktop 10 for integrated lighting. These light sources 40 are substantially located inside the intake duct 31 or intake opening 30.

[0079] This lighting source can illuminate a space as ambient lighting. The brightness and / or color can be changed by the fan speed. The lighting can also have functions such as residual heat display; the brightness or color of the light can be changed according to the temperature.

[0080] The lighting source can also be used as a notification function, for example flashing after a cooking zone timer or egg timer has expired, in addition to or instead of the acoustic signal.

[0081] Furthermore, the lighting source can be designed as a warning function, for example if at least one cooking zone has been switched on but no further operation has been carried out after a defined period of time. This can act as a kind of "no-answer switch" to remind the elderly or forgetful people that the cooking process has started, for example, before the cooker is completely switched off.

[0082] In this exemplary embodiment, the light source 40 is designed as an LED, which is controlled by a light controller 41 and emits light from the cooker 10 through an optical fiber. Figures 1 to 4 It can be further clearly seen that the light source 40 is laterally located in the suction opening 30 in the suction duct 31 for indirect lighting. Therefore, the light source 40 can be located at the side so as to illuminate at a certain angle, or it can illuminate indirectly or below so as to illuminate directly from the suction duct 31 outward.

[0083] In this example, the light source 40 can be activated by the light controller 41, such as Figure 5 The communication device is connected to the light controller 41 and is designed to communicate with an external control device / receiver, preferably via wireless communication such as WLAN, Bluetooth, etc.

[0084] The light controller 41 is designed to activate the light source 40 after the communication device receives the control signal so that the light source 40 radiates light from the cooker 10 , thereby generating ambient or background lighting in the space around the cooker 10 .

[0085] In this example, in order to realize bidirectional transmission of data, the light controller 41 is connected to the control and / or regulation device 6 , which is used to control and / or regulate the energy of the heating unit 4 of the cooker 10 .

[0086] from Figure 5 As can further be seen in FIG. 8 , the at least one light source 40 can be operated by using an operation sensor 9 .

[0087] The brightness and / or color of the light of the at least one light source 40 is / is adjustable, in particular the color of the light is automatically adjustable, for example depending on the ambient noise.

[0088] Figure 5 It is also shown that a sensor system 5 comprising sensors for measuring temperature and / or for measuring movements / vibrations and / or for measuring weight is provided, which sensor system 5 is connected, in particular, to a control and / or regulating device 6 for signal transmission.

[0089] Figure 6 and Figure 7 Further exemplary embodiments of the cooktop 10 are shown. Figure 6 This exemplary embodiment is shown in a) a top view, b) a first side view and c) another side view.

[0090] and Figures 1 to 5 Compared to the variant shown, Figure 6 and Figure 7 The cooker 10 shown has no fan motor integrated into the cooker 10. Here, the fan motor is not located at the frame 15 of the cooker 10 below the cooker panel 1, but can be located externally, for example in a separate housing at the wall or cabinet base.

[0091] Since the light source 10 is located in the stove 10 , the stove 10 can be used to illuminate the space where the stove 10 is located.
