Definitions

  • the invention relates to the operation of a stove.
  • the invention relates to the operation of an induction cooker with an induction coil, which can be arranged in or under a worktop.
  • An induction cooker includes an induction coil that is placed in or under a worktop.
  • a cookware such as a pot or pan can be placed on the worktop and heated there without contact by means of electromagnetic induction.
  • Such an arrangement is also called “induction under worktop” and enables the flexible use of a horizontal surface as a stove or as a worktop.
  • a control element attached to the worktop can optically break through the working surface. This can destroy the integrative and seamless character of the approach. At a transition between the control element and the rest of the worktop, a joint can arise, which can be difficult to clean.
  • One object of the present invention is to provide an induction cooker which can be better integrated with a worktop.
  • the invention solves this problem by means of the subject matter of the independent claims. Un claims describe preferred embodiments.
  • An induction cooker includes an induction coil which is set up for attachment under a work surface; an operating device that is set up to visualize an input field in the area of the work surface; a control device for controlling the induction coil as a function of an actuation of the input field; and a functional element which is set up for attachment to the work surface such that it extends upward from the work surface.
  • the control device is attached to the functional element.
  • the work surface can in particular comprise the surface of a worktop.
  • the induction coil can be attached under the worktop or left in the worktop.
  • the surface of the worktop can be closed and optically uniform.
  • the stove can be better integrated with the worktop and the worktop or the work surface can be cleaned more easily.
  • a connec tion in particular a wiring between the operating device and the Steuerervor direction can be simple. Additional controls, for example in a front of a piece of furniture arranged below the work surface or above the worktop, for example in an overhead extractor hood, can be omitted. Intuitive control can be achieved by integrating the operating device with the functional element. In addition, functions of the operating device and the func tional element can be coordinated.
  • the functional element comprises an infrared sensor, the control device being set up to control the induction coil as a function of a signal from the infrared sensor.
  • the infrared sensor can, in particular, sense the temperature of a cookware heated by means of the induction coil, so that compliance with a predetermined cooking temperature can be monitored, or the creation or overcooking of a food in the cookware can be avoided.
  • the functional element comprises a suction device.
  • the suction device is preferably set up to extract air laterally or downward from the area above the induction coil. Odors, vapors or grease splashes can be removed from the cooking area or from surrounding air.
  • the extracted air is usually conveyed under the work surface, optionally filtered and expelled inside or outside. Because of the downward suction, the arrangement is also referred to as a downdraft hood. It was known that the usual height of such a suction device above the worktop can be used in part for the attachment of the operating device.
  • the induction cooker can comprise a device for detecting an actuation of the input field, the device being arranged for attachment below the work surface. If the working area delimits a worktop, the device can, for example in the form of a capacitive proximity switch embedded in the worktop or attached under the worktop.
  • Alternative devices include, for example, a sensor based on ultrasound or radar. In this variant, the position of the input field can be fixed, but the visualization of the input field can be controlled as required.
  • the operating device comprises a projector and an optical sensor for scanning an actuation of the input field.
  • the sensor and the projector are attached to the suction device at a predetermined distance.
  • the distance can be effective in particular in the horizontal direction.
  • the actuation of the input field can be determined more precisely. In particular, the exact point in time at which the work surface is touched in the area of the input field or the exact location of the touch can be determined with improved accuracy.
  • the projector can work with visible light and the sensor optically with invisible light.
  • the sensor can, in particular, work on the basis of infrared light and determine whether the input field is actuated by a warm object, in particular the hand of a user.
  • the heat of the object can be limited to a predetermined temperature range to ensure that no inanimate object such as a kitchen utensil or cookware accidentally actuates the input field.
  • the functional element can be firmly attached to the work surface, so that it permanently extends upwards from there.
  • the functional element can also be countersunk in the work surface.
  • a particularly telescopic elevation mechanism can be provided in the worktop. If the functional element is completely recessed, its surface can be flush with the work surface.
  • the functional element can also include a main switch.
  • the main switch can control operation of the induction cooker. In particular, the heating of a cookware by means of the induction coil can be prevented when the main switch is switched off. If the functional element also includes a suction device, this can also be in operation when the main switch is switched off.
  • the main switch can advantageously be provided in the variant with a retractable functional element. For example, the main switch can turn on the induction cooker if that Functional element is moved up out of the work surface. The retraction can be done manually or, for example, motor or spring controlled.
  • the operating device is set up to project information onto the work surface.
  • the information is usually directed to a user of the induction cooker and can in particular comprise an operating state or a prompt.
  • a location at which the input field is projected onto the working surface can be selectable within predetermined limits.
  • the operating device can be movably attached to the functional element.
  • the operating device is set up to project information onto a vertical surface in the area of the work surface.
  • the vertical surface can extend on a side facing away from a user of the induction cooker or on the side of the induction cooker.
  • Several input fields can also be projected at different locations. These locations can be on the same or on different areas.
  • Figure 1 is a schematic representation of an exemplary induction cooker
  • Figure 2 is a view of an induction cooker in a further embodiment
  • Figure 3 illustrates an exemplary suction device for an induction cooker.
  • FIG. 1 shows a schematic illustration of an exemplary induction cooker 100.
  • the induction cooker 100 is mounted in the region of a work surface 105 which preferably extends in the horizontal direction and in particular can comprise the top of a work surface 110.
  • a cookware 1 15 can be placed, which can be electromagnetically excited and thus heated by an induction coil 120, which is located in or below the work plate 1 10.
  • the worktop 110 is preferably heat-resistant.
  • a controller 125 is set up to control the induction coil 120 and can be attached to the underside of the work surface 105.
  • a functional element 130 extends from the work surface 105 in the vertical direction upwards.
  • the functional element 130 can be attached rigidly or countersunk relative to the work surface 105.
  • a mechanism is preferably provided which allows a telescopic vertical movement of the functional element 130.
  • an upper surface of the functional element 130 is preferably essentially flush with the work surface 105.
  • the functional element 130 preferably fulfills at least two tasks which are functionally related to the operation of the induction cooker 100.
  • a first task is accomplished in such a way that the functional element 130 extends over the work surface 105 at least when the induction cooker 100 is in operation.
  • a second task takes advantage of this in that the functional element serves as a carrier for an operating device.
  • a main switch 135 can be coupled to the functional element 130, which can control a function of the induction cooker 100. In particular, operation of the induction coil 120 can be prevented when the main switch 135 is open. If the functional element 130 is vertically movable, the main switch 135 can be closed when the functional element 130 is extended vertically.
  • the first task can include a suction device 140, which is set up to extract fumes, vapors or fat mist in the area of the induction cooker 100 and in particular in an area which is provided for storing the cookware 115.
  • the suction device 140 can comprise a fan, a drive motor, a filter or a separating device for water or fat.
  • a labyrinth filter is provided which can be removed and cleaned, for example, in a dishwasher.
  • the control device 125 can control an operation of the suction device 140.
  • the suction of air can be controlled as a function of heating of the cookware 115.
  • the first task can also include an infrared sensor 145, which is set up to determine a temperature of an object in the region of the work surface 105.
  • the object can in particular comprise the cookware 115 and a scanning area of the Infrared sensor 145 may face induction coil 120 on the top of work surface 105.
  • an input field 150 can be provided, which is located on the surface of the work surface 105 in the illustrated embodiment.
  • the input field 150 can also be formed on another surface, in particular on a vertical surface such as a wall or a cheek of a piece of furniture in the area of the work surface 105.
  • An actuation of the input field 150 can be detected by the control device 125 and the induction coil 120 can be controlled depending on the detected operation.
  • a sensor 155 is provided, which can be attached in particular under the work surface 105, for example in or under the work surface 110.
  • the sensor 155 can work capacitively, for example, as a proximity switch. A resolution of the sensor 155 can be selected depending on the complexity of a desired input field 150.
  • the operating device 160 is set up to visualize the input field 150.
  • the visualization should be visually accessible to a user in the area of the work surface 105.
  • the operating device 160 can in particular comprise a projector 165, which provides a projection as a visual indication or visualization of the input field 150 from an elevated position above the work surface 105.
  • the operating device 160 additionally comprises an optical sensor 170, for example a camera, which is set up to optically detect an actuation of the input field 150.

  • the optical sensor 170 can comprise a depth camera in addition or as an alternative to a conventional optical camera.
  • the depth camera comprises two cameras spaced apart from one another and the distance of a pixel from the cameras is determined by means of triangulation.
  • the depth camera comprises a light source and is set up to determine the time between the emission of light and the arrival of light reflected on the object (“time of flight camera”). The light used for this can be particularly in an invisible range, such as in the infrared range.
  • the optical sensor 170 and the infrared sensor 145 are embodied integrated with one another. In this case, the optical sensor 170 comprises an optical camera which is set up to work in the infrared range.
