Definitions

  • the invention relates to a radiant heater according to the preamble of the claim 1.
  • Such radiant heaters usually have a support for an electrical heating to be operated consisting of heating resistors.
  • Such heating resistors are made by a glass ceramic plate, stainless steel plate or the like Plate or disc covered, which serves as a hot plate with its top. Due to their structure, such radiant heaters form together with the glass ceramic plate a carrier space essentially closed to the outside, in which the radiant heating resistors are used. To overheat the glass ceramic plate To avoid, temperature limiters are used in such radiant heaters or temperature monitor used.
  • DE 33 15 657 A1 is an electric cooking appliance with a glass ceramic plate known, which has a central opening with a sleeve inserted therein, in which a temperature sensor is arranged.
  • the temperature sensor is in the sleeve is held displaceable by spring force up to an upper stop, whereby the temperature sensor when touching the stop slightly above the The surface of the glass ceramic hotplate protrudes.
  • thermo limiter for a glass ceramic cooking unit is known from EP 0 141 923 B1.
  • it runs the temperature sensor preferably approximately along a diameter over the Cooking area or a little laterally offset to the cooking area.
  • the temperature sensor itself consists of several partial bars, which are in a uniform, elongated Outer tube are housed. This configuration of the temperature sensor it becomes possible to differentiate the resulting from the at least two heating surfaces Communicate temperature influences to the temperature sensor so that the Response temperature of the temperature sensor is actually independent of whether one or two heating surfaces are in operation.
  • the particular advantage of the invention is seen in the fact that the temperature sensor or sensor of a temperature limiter exactly on the hottest point on the underside of the plate is aligned and thus optimally fulfills the task. Under this orientation is understood in the sense of the invention that the to be detected hottest area as a so-called measuring zone directly on the plate or between the plate made of stainless steel or glass ceramic and the radiant heating can lie.
  • the measuring zone does not necessarily have to be punctiform, but can also between the radiant heater and the plate or cover in diameter of, for example, about 15 mm.
  • the detection of the temperature then usually takes place punctiform. This will act as a temperature monitor fulfilled and usable cooking processes are possible because a temperature limit and a response to the temperature rise as well on the drop in temperature is created.
  • the sensor was usually in the middle of the radiant heater set because this is considered the production best solution with enough space applies.
  • the result of the measurement for the temperature would have to be in the evaluation electronics an assignment of heating type, power and temperature difference from Measuring point to the hottest point of the glass ceramic plate. This is technical very complex and complicated and also causes high costs. Therefore In practice, the temperature was measured linearly over the center of the heating to be carried out indirectly using an expansion rod.
  • the temperature sensor for example a thermocouple, one for each design Radiant heater is placed at the type-specific, hottest point.
  • This limit temperature is chosen so that the limit temperature of the glass ceramic plate under all operating conditions is observed.
  • the limit temperature can nevertheless advantageously be so be chosen high so that the usability of the entire system becomes what u.a. leads to shorter heating times.
  • the temperature limiter sensor is brought as close as possible to the underside of the glass ceramic plate. An optimum is achieved when the sensor is on the underside of the glass ceramic plate contacted.
  • the radiant heater 1 consists essentially of a bowl-shaped Carrier 2, the bottom of which is arranged substantially parallel to the glass ceramic plate 3 is.
  • the cup-shaped carrier 2 is made of metal.
  • the Insulation carrier 4 made of ceramic insulating materials used, for example brought into a structured form by pouring, pressing and drying become.
  • the top of the insulation support 4 are the spiral or helical arranged channels or tracks 6 for receiving the or the radiant heating resistors 7th
  • the glass ceramic plate 3 lies on the annular outer edge 5, whereby between the radiant heating resistors 7 and the underside of the glass ceramic plate 3 results in a free, closed space 8.
  • the temperature limiter 11 consists of a temperature sensor or sensor 12, which is located inside a tube 13.
  • a temperature sensor or sensor 12 is located inside a tube 13.
  • the temperature sensor 12 is located at its outer end in a short distance from the underside of the glass ceramic plate 3 and is exactly on the hottest point 10 aligned.
  • thermocouple (temperature sensor 12) is in a radial Channel between the bottom of the carrier 2 and the insulation carrier 4. Below the hottest point 10, the thermocouple 12 is bent at right angles and runs in an upright ceramic tube 15, which with a short distance below the glass ceramic plate 3 ends.
  • FIG. 5 shows, there is an inner sleeve in the ceramic tube 15 as the outer sleeve 16 used, within which the temperature sensor 12 up to the plant Bottom of the glass ceramic plate 3 runs.
  • the inner sleeve 16 is under the Effect of a spring 17, whereby the inner sleeve continuously to the bottom the glass ceramic plate 3 is pressed.
  • the inner sleeve 16 under the action of a so-called thermal bimetallic spring 18, thereby achieving is that the inner sleeve 16 in the cold state of the radiant heater 1 or the glass ceramic plate 3 at an axial distance from the bottom of the Glass ceramic plate 3 is located.
  • the inner sleeve 16 In the hot operating state of the glass ceramic plate 3, the inner sleeve 16 by the bimetallic spring 18 against the underside of the Glass ceramic plate 3 pressed.
  • the temperature sensor 12 is with its outer End embedded in an insulating material 19 within the inner sleeve 16 and lies punctiform on the underside of the glass ceramic plate 3.
  • the ceramic tube 15 or the inner sleeve can 16 be open with the end facing the glass ceramic plate 3.
  • the front end can also be closed, as shown in FIG. 6.
  • alternative can be closed by an adhesive or other sealant. This has the advantage that oxidation and aging of the thermocouple 12 is prevented becomes.
  • the temperature sensor 12 contacts the Bottom of the glass ceramic plate 3 only under the influence of temperature.
  • FIG. 7 is a further embodiments of a horizontal Installation of the temperature sensor 12 shown. It can be seen in FIG. 7 that that the temperature sensor 12 in a jacket tube, which, for example, a Quartz tube, a metal tube or a ceramic tube 13 may be introduced.
  • the sensor head 20 of the temperature sensor 12 can be placed on the outer tube 13 Cap 21 covered, providing heat and radiation insulation is caused.
  • the sensor head 20 is located with the cover 21 in the hottest area 10, which is between the plate 3 and the radiant heater 7 is located and is highlighted by dashed lines.
  • the sensor head 20 is the temperature sensor 12 reset behind a small front opening of the outer tube 3.
  • the small end opening of the outer tube 13 in turn protrudes into the measuring zone defined hottest area.
  • the outer tube extends into the measuring zone or the hottest area 10 13 with internal temperature sensor 12 at right angles to the glass ceramic plate 3 bent and stands with its open face directly on the Bottom of the glass ceramic plate 3.
  • the sensor head 20 is very small Distance below the underside of the glass ceramic plate 3
  • Outer tube 13 is again in the hottest area 10 as a so-called Measuring zone.
  • sheets could be directly on the underside of the glass ceramic plate be applied as a temperature sensor at a measuring station with a Pt element are connected.
