  • the door opening device for automatically moving the door can, for example, have an electric drive in the form of a motor.
  • the door opening device has a mechanical drive, which moves the door from a closed to an open position. It is thus clear that any device which is able to move or displace the door at least in sections between a closed position and an open position can be provided as the door opening device. In this context, it can also be provided, for example, that the door opening device works hydraulically.
  • the detection device represents a device that is set up to detect an element located in the vicinity of the detection device.
  • the detection device has a predetermined range within which an element to be detected must be present so that it is detected in order to trigger further subsequent processes and functions.

  • the at least two sensors are arranged at a distance of 300 to 420 mm.
  • the distance can correspond to a maximum width of the triggering element to be detected and/or a maximum distance that can be detected. That is, the at least two sensors can be arranged at such a distance that a signal is only generated simultaneously by both sensors in the event that a triggering element with a sufficient width is detected. This makes it possible to ensure in an intelligent manner that the sensors are only triggered when a suitable triggering element is located in front of the cooking appliance or the sensors.
  • the cooking appliance according to the invention With the help of the cooking appliance according to the invention, it can be achieved in a particularly reliable and safe manner that the door is opened automatically and at the same time the risk of incorrect operation is minimized.

  • the retractable door can be moved or retracted into a receiving space from the closed position into the open position during an opening process.
  • a handle arranged on the front side of the door moves from a closed position into an open position during the opening process.
  • the handle can be set up to turn by approximately 90° in the direction of a user standing in front of the cooking appliance during the opening process, so that the user can better grip the handle when the door is open.
  • the retractable door can increase the comfort for a user, since there are no disruptive components between him and the cooking appliance that could impede an operating process.
  • the at least two sensors are arranged at a distance of 330 to 390 mm, particularly preferably 360 mm.
  • the at least two sensors can preferably be aligned symmetrically in relation to a vertically running center line of the cooking appliance and/or the panel. This makes it possible, for example, on the one hand to simplify operation for a user and on the other hand to improve the visual appearance.

  • the positioning line thus represents an aid or marking for a user, which supports him in aligning the triggering element with the detection device or the sensors.
  • the positioning line can correspond to the width of the predetermined triggering element and/or the distance between the at least two sensors. A reliable alignment of the triggering element can be improved by means of the positioning line and thus reliable operation can be ensured.
  • the panel can preferably be printed with the positioning line.
  • the screen can be made of glass, for example, or can have glass at least in sections, on which the positioning line is printed. Printing is a cost-effective and visually appealing way of attaching the positioning line.
  • the door opening device is set up to move the door from the closed position to the open position after the triggering element has been detected by the detection device for a predetermined time.
  • the triggering element must be held in front of the detection device or the sensors for a predetermined time in order to enable the door opening device to be activated.
  • an electrical signal is only generated by the detection device or the sensors when they detect the triggering element for a predetermined time without interruption. This reduces the risk of incorrect operation. This means that a possible operating error caused by children running past, for example, which can take less than the specified time, can be avoided in this way.
  • the separate triggering element can be a food support, in particular a baking tray, grid or the like, which can be present as an accessory in the respective cooking appliance and can be used for baking/cooking food.
  • a food support in particular a baking tray, grid or the like, which can be present as an accessory in the respective cooking appliance and can be used for baking/cooking food.

  • the door opening device can be controlled to move the door from a closed position to an open position after detecting the triggering element for a predetermined time. This means that only after a specified time has elapsed, within which the triggering element must be held in front of the detection device without interruption, so that the detection device is triggered, is the door opening device activated by means of an electrical signal generated by the detection device, so that only after this time has elapsed The door is opened. In this way, it can be guaranteed in a very reliable manner that the door is only opened when this is desired by the user.
  • the door opening device is only activated to move the door when the at least two sensors are triggered by the triggering element simultaneously and for a predetermined time.
  • the triggering element provided for this purpose, for example in the form of a baking sheet, is used.

It is also conceivable that the door 6 can be automatically transferred from the open position to the closed position, for example by pressing a button (not shown) for this purpose.
  • the opening process of the door 6 is started by holding the triggering element in the form of a baking tray in front of both sensors simultaneously for a predetermined time, for example 3 seconds. After the predetermined time has elapsed, an electrical signal generated by the detection device 20 or the sensors 21 is transmitted to the door opening device 10, after which the door 6 automatically begins to open. Opening of the door 6 is only achieved by the direct arrangement of the baking tray in front of the sensors for a predetermined time and the simultaneous triggering of the two sensors. In the exemplary embodiment shown, the door 6 is retracted or lowered into a receiving space 4 arranged below the cooking space 2 .
