Definitions

  • the invention relates to extractor hoods, in particular extractor hoods for extracting cooking vapors by means of an air flow, with a housing which has at least one air intake opening and at least one air outlet for the air flow, at least one fan arranged in the housing for generating the air flow, and at least one fan in the housing separating element arranged in the air flow between the air intake opening and the fan for separating one or more components of the cooking vapors, in particular fat and/or oil, in the air flow, the air flow in the housing being guided from the air intake opening via the separating element to the fan and from the fan is blown out of the housing via the air outlet.
  • the extractor hood has at least one motorized height adjustment device for changing the vertical distance of the extractor hood from the hob. Because a first gesture detection device is set up to detect gestures of an operator of the extractor hood and convert them into control signals for controlling the height adjustment device, the extractor hood can be operated easily, intuitively and safely. The vertical distance between the extractor hood and the hob underneath can be changed simply by gestures of an operator. This means that the extractor hood can be brought to the optimum height for cooking using the motorized height adjustment device without having to touch the extractor hood or use a remote control.
  • a gesture by the operator in which the operator's hand is moved from bottom to top, can trigger activation of the height adjustment device, which results in an increase in the vertical distance between the extractor hood and the hob.
  • a gesture by the operator in which the operator's hand is guided from top to bottom can trigger activation of the height adjustment device, which results in a reduction in the vertical distance between the extractor hood and the hob.
  • a gesture by the operator in which the operator's hand is guided from left to right can cause an increase in the power of the fan. While, for example, a gesture by the operator, in which the operator's hand is moved from right to left, can result in a reduction in the performance of the fan. Furthermore, for example, a gesture by the operator, in which the operator's hand is moved from front to back, can cause lighting to be switched on. For example, while a gesture by the operator at which the operator's hand is moved from the back to the front, can result in the lighting of the extractor hood being switched off. In addition to controlling the height adjustment device, other settings can also be made on the extractor hood via the gesture detection unit according to the invention. This enables easy, intuitive and safe operation of the extractor hood.
  • the gesture detection device comprises an optical ToF sensor which is designed to detect the distance between the extractor hood and the hob and which is also designed to detect the change in the distance between the extractor hood and the hob over time To capture the operator's hand when performing a gesture.
  • the optical ToF sensor By measuring the distance between the extractor hood and the hob, the current position for the extractor hood and the optimal position to be reached for cooking can easily be determined using the optical ToF sensor.
  • the height adjustment device can also be controlled via the temporal change in the distance between the extractor hood and the operator's hand when performing a hand gesture, which results in optimal positioning of the extractor hood with regard to the vertical distance to the hob. Since the ToF sensor can be used both to record gestures from an operator and at the same time to record the vertical distance of the extractor hood to the hob, multiple sensors are not required to determine this information.
  • An embodiment that provides that the gesture detection device is set up to respond only to gestures that are performed in an area below the extractor hood and above a minimum distance from the hob surface is particularly preferred.
  • the minimum distance from the hob surface operating errors via the gesture detection device can be prevented very easily, since this distance from the hob surface prevents the gesture detection device from responding to movements by the operator when cooking on the hob.
  • ingredients of the dishes can be easily added to the cookware provided by hand on the cooktop, or the contents of the cookware can simply be turned or stirred without the gesture detection device responding to these movements of the operator when cooking on the cooktop.
  • To operate the hood the operator must perform a hand gesture in an area below the hood and above the minimum distance from the hob surface. All you have to do is lift your hand into the detection area above the minimum distance from the cooktop surface.
  • a particularly advantageous embodiment of the invention relates to the fact that the minimum distance is 10 cm to 60 cm, preferably 20 cm to 40 cm. With such a minimum distance, cookware and ingredients can be easily manipulated on the cooktop during cooking without the gesture detection device responding to these hand movements. This ensures simple, intuitive and safe operation of the extractor hood.
