Definitions

  • the invention relates to a display device for a household electric heater according to the preamble of claim 1.
  • Such electric heaters are in particular glass ceramic cooktops, wherein under the cooktop a radiant heater can be arranged.
  • a device of this type shows the font US-A-6,369,365 ,
  • the electric heater has at least one heating device, which is divided into a plurality of areal heating areas, wherein the heating areas can be at least partially independently or individually activated for the heating operation.
  • This is, for example, a radiant heater with inner circle and outer circle.
  • the outer circle is activated in addition. Likewise, these are forms for roasting.
  • an LED is activated, which indicates the activation of the outer zone by their illumination.
  • additional heating areas which are arranged just to the side of a round zone, and also to indicate their activation via an LED.
  • the invention has for its object to provide a display device mentioned above, which displays a more comfortable and more detailed display of the operation of individual heating areas of a heater, in particular a faster and instinctive detection of the displayed state should be made possible by a user.
  • the lighting devices are formed as separate segments of a geometric basic shape.
  • a geometric basic form is a circle or a rectangle, or a square.
  • two basic forms are the same per display device Art provided with different size and concentric arrangement. This symbolizes, for example, an aforementioned inner circle and outer circle.
  • At least one further lighting device with at least one segment in addition to the at least two concentric basic shapes, which has a small distance from the basic shapes or the larger of the two basic shapes.
  • the division of the further lighting device into segments again enables the previously described detailed representation of states or information. It is possible to form this further lighting device in the manner of a half or half-divided basic shape, next to which it is arranged. If the basic shapes are circles, then the further lighting device is a semicircle or has segments which form a semicircle.
  • Such a laterally arranged further lighting device is preferably designed in the same way as the other lighting devices, ie at least with one segment.
  • all segments of a display device are of the same kind, even if they differ in size. This allows a uniform type of presentation, which is advantageous for the rapid acquisition of the information.
  • the two basic shapes an additional third basic shape, which is also similar and is arranged concentrically to the other two basic shapes. However, it differs in size. It is advantageous here if, with three concentric and similar basic shapes, the size differences are linear relative to one another in the form that, for example, one step each from a smaller shape to the larger basic shape involves a change in diameter with a fixed amount. This can be for example 3mm, 4mm or 5mm.
  • the basic shapes are circular. This is because usually also the radiant heaters and thus the light images generated by these are round.
  • the segments may be formed as angular sections of the basic shape.
  • They extend over an angle of 90 °, so that a basic shape is divided into four segments.
  • the segments can on the one hand be flat, so for example be quarter circles.
  • the segments can either merge seamlessly with each other such that when all the segments of a basic shape are illuminated, they become a closed one and form continuous area. Alternatively, they may be separate from each other or have a slight distance from each other. This is possible by unlit webs or separation areas. Such displays correspond approximately to so-called seven-segment displays. Again, there is a separation of the individual segments. Thus, both a production easier possible and the type of presentation is usually pleasant.
  • the lighting devices are formed in an advantageous embodiment of the invention so that they represent different sized heaters or heaters with inner circle and outer circle and heaters with laterally adjacent arranged additional heating areas by appropriate replica of the heating areas with the segments.
  • luminous segments indicate which heating areas are active. Above all, they indicate this by their approximate arrangement or assignment to each other. In this way, it is very easy for the user to quickly and intuitively capture the displayed information.
  • a lighting means illuminates at least one segment, possibly also several segments.
  • a luminous means illuminates two segments, which form a half basic shape or half of a basic shape.
  • the choice of bulbs is basically diverse.
  • LEDs are used because they are available in different colors and shapes.
  • the lighting means for example as an LED, have a body which has segmental shape.
  • a light source with such a body thus forms a lighting device and is advantageously a component or a structural unit.
  • an LED can be a plastic body with the segment shape, For example, quarter-circle or quarter-circle shape, have.
  • the lighting means may have any shape. They are arranged under a mask or cover which has openings or translucent areas with the shape of the segments. It is thus possible, as it were, to arrange a mask over any light source which generates the segment shape.
  • the light source parts which are lichtver named or light-conducting.
  • transparent or colored plastic is advantageously used.
  • Such light-distributing or light-conducting elements are advantageous when it comes to distributing substantially point-shaped lighting devices, bulbs or light sources evenly on the planar segment shape. For example, these may also be scattering films or the like.
  • the display device can have a housing with a plurality of electrical connections which are connected to the lighting means. Furthermore, a mask is provided which has openings corresponding to the shape of the segments. Such a unit is a single component, for example, according to a seven-segment display.
  • a structural unit which has openings or translucent areas that correspond to the shape of the segments of the display device.
  • the assembly can be mounted on separate bulbs, which are mounted for example on a printed circuit board.
  • the display device is advantageously connected to a controller, which is in particular also a controller for the electric heater. It can be provided per heater, which forms a hotplate of the electric heater, a display device, which just represents the state of this heater.
  • the controller is designed such that it can represent the operation, ie the heating region of the heating device to be changed by means of the lighting devices or the individual segments of the display device. Such a controller may have a similar operation as one with which seven-segment displays are driven.
  • the circuit board has next to circuit components and electronics, in particular for the heater, at least one display device according to the invention.
  • a display device is provided per heating device.
  • the control or the printed circuit board per heater on at least one control element, for example, touch switch.
  • such a display device is arranged, advantageously at a small distance. This makes it clear that this display device indicates the state of a heating device, which can be operated with the operating device just.
  • a display device 11 has a rectangular mask 13.
  • This mask contains segments which are, for example, openings in the mask, wherein the mask is otherwise opaque and the openings are translucent.
  • central basic shapes 15 are provided in a circular shape.
  • the innermost basic shape consists of innermost segments 17, the central basic shape consists of middle segments 19 and the outermost basic shape consists of outermost segments 21.
  • the three basic shapes are each formed by quarter-circular arc segments 17, 19 or 21. They are numbered clockwise with a to d.
  • the central basic shape or the middle segments 19 forming these are arranged in accordance with their size to the right of the basic shapes 15 lateral lighting devices 23. These consist of two lateral segments 25a and 25b. They are the middle segments 19 formed accordingly, ie quarter-circular arc segments. They correspond approximately to the middle segments 19a and 19b and are only shifted to the right to the side. Thus, when the left middle segments 19c and 19d and the two side segments 25a and 25b are alone in operation, an elongated heating zone may be displayed. This corresponds to a roasting pan described above. Its shape is familiar to a person skilled in the art and therefore does not need to be explained in detail here.
  • Fig. 1 should emerge especially a way of training lighting equipment or segments.
  • the embodiment described there is just with a mask and arranged in this mask segments 17, 19, 21 and 25.
  • either each of the segments can be individually illuminated for themselves.
  • a controller 30 shows, with the four heaters can be controlled.
  • a display device 11 a seven-segment display 32, in particular for a cooking level display, and two touch switches 34 are provided for each heating device.
  • the touch switches are a plus switch and a minus switch to increase or decrease the power of the hotplate. This power is then displayed with the seven-segment display 32.
  • a further touch switch 36 is provided, which can serve to activate the hotplate at all or to activate an operation by means of the touch switch 34.
  • the additional touch switch 36 it is also possible, for example, certain additional circuits or heaters or other heating areas of a heater of a hotplate on or off. In itself, such a control, in particular with the touch switches 34 and 36, known. In this respect need not be further discussed here.
  • the hotplates can be radiant heaters, for example, as previously indicated.
  • the display 11a indicates the operation of a heater in which an innermost and a middle cooking zone are active. This can be seen from the fact that in the display device 11a, the innermost segments 17 and the central segments 19 of the central basic shapes 15 light up. The lighting is to be illustrated by the fact that the corresponding segments are shaded dark.
  • the display device 11b at the top right indicates that the relevant heating device is operated with three concentric heating areas.
  • the display device 11 d bottom right lights up with the two left middle segments 19 c and 19 d of the central basic form 15 and the lateral segments 25 a and 25 b of the side lighting devices 23.
