Definitions

  • the invention relates to an electric radiant heater with an active sensor for detecting the positioning of a cooking vessel on a cooking plate covering the radiator according to the preamble of claim 1.
  • Such sensors are used to detect whether and possibly where a cooking vessel is on the hotplate.
  • the heater is activated only when the cooking vessel is attached. This is done on the one hand to avoid wasting energy by not fitted cooking vessels and on the other hand the risk of burning or destruction of objects by hot, so to speak, open-running hotplates.
  • the sensor according to DE 196 03 845 A1 is formed as a loop of wire, which runs substantially in a round shape between the radiator and hotplate.
  • the placement of a corresponding metallic cooking vessel causes a change in the inductance of the sensor loop.
  • This change is detected by an associated electronics as placing a cooking vessel.
  • the heating can be activated as intended. Difficulties arise from the attachment of the sensor to the radiant heater.
  • there are problems with the mass of the sensor in particular in a so-called drop test, in which the sensor can damage, for example, a glass ceramic plate as a hob.
  • the invention has for its object to provide an aforementioned electric radiant heater in which the attachment of the sensor is simplified to the radiant heater and the sensor has an improved structure.
  • the senor is formed without a loop, in contrast to the known and common round sensor loops or coils. He runs substantially straight, preferably at least in the essential sections of its course. It particularly preferably runs in the region of the radiant heater or the heating zone exclusively in a substantially straight line.
  • loopless means that the sensor is not completely or completely closed loop forms for the most part. The sensor preferably does not limit any area in its course.
  • a sensor according to the invention has the advantage that the structure can be considerably simplified.
  • On the radiant heater is not an entire, circumferential loop to install, which may also have several turns, but only straight sections. These can be fastened, for example, with at least one end to the edge of the radiant heater or a surrounding this insulation.
  • loop-shaped sensors have the disadvantage that they do not accurately detect the central zone of the radiant heater because they do not directly cross it. Due to their circumferential, loop-like character, no section can be passed through this central area. By contrast, guiding a straight sensor over this central area is not a problem.
  • the senor can have only one section running over the heating zone, for example, it can be designed as a straight electrical conductor. It can range from one edge of the radiant heater to above its middle, preferably to the other edge. Such a sensor does not include any surface at all.
  • the function or the recognition accuracy as well as the parallel conductors described above as sensors can be decided whether a cooking vessel was placed on or whether this cooking vessel size or position is accepted.
  • the senor extends across a heating zone or the entire radiant heater.
  • radiant heaters which have a metal plate which substantially supports or contains the radiant heater.
  • the metal plate can be designed as a return conductor or second connection for the sensor. So can be omitted here consuming additional connection work. It has surprisingly been found that thereby the function of such a cooking vessel detection sensor is not affected.
  • This may be such that the sensor is electrically insulated from the metal plate of the radiant heater at least at one of its end regions. With this insulated end portion it is connected to an externally accessible first electrical connection. The other end of the sensor is electrically connected to the metal plate, directly or indirectly.
  • a second electrical connection needs to be attached only at an arbitrary position on the metal plate in order to be electrically connected thereto.
  • connection block can be fastened to the radiant heater or the metal plate in the vicinity of a sensor end.
  • the metal plate is very easy to tap this signal at any point or to arrange the connector stone very close to one end of the sensor.
  • the senor extends centrally over the heating area of the radiant heater. This can ensure that a cooking vessel placed on the associated hotplate covers the sensor in almost any sensible position and allows it to be detected.
  • the sensor can run over more than one heating region, in particular all heating regions.
  • the senor it is possible to attach the sensor to the radiant heater in such a way that, when the radiant heater is mounted, it runs a short distance below a cooking plate to which the radiant heater is mounted.
  • This small distance can be 0.1mm to 10mm, preferably be very small and be a few 1 / 10mm.
  • the upper edge of the radiant heater surrounding the insulating plate or the like can be taken, which rests in the mounted state on the underside of the hotplate.
  • the senor may have at least one of its ends a height adjustment, so that a desired distance can be set accurately.
  • a height adjustment can, for example, have a slot, preferably in a direction perpendicular to the plane of the radiant heater, on the radiant heater itself. Along this slot, the sensor can then be adjusted in height.
  • the senor rigid, preferably as a thick wire or tubular.
  • a metal tube offers itself, which can be electrically insulated to the outside.
  • the sensor can be combined with a rod regulator usually used for radiant heaters.
  • the metallic outer tube of the rod controller can form the sensor or be used as an electrical conductor for this.
  • a commonly used rod controller can be grown with a residual heat contact to the radiant heater and designed as a sensor. If the residual heat contact of the rod controller is not required, the space that has become free in the rod regulator can be used as a connection block for the sensor connection.
  • the senor may be elastic or flexible.
  • a wire, a wire or a metal band to offer can be stretched over at least a portion of the heating area and gain their stability by the tensioning.
  • spring means can be provided to compensate for a thermally induced change in length of the sensor.
  • the spring means may be used for supporting at least one end of the sensor and / or for maintaining the voltage and thus the shape of the sensor.
  • the spring means should be constructed so as to allow for accurate, position-defined mounting.
  • the spring force should be matched to the time / Temperaturdehngrenze the sensor material or to the cross section of the sensor. This can ensure that the system sensor / spring means is optimally matched.
  • a leaf spring is used as the spring means, which can even be punched out and exposed in an embodiment of the invention, even from the metal edge of the support plate for the radiant heater.
  • the spring means can be electrically insulated from a metal plate for receiving the radiant heater.
  • the spring means serve just for electrical connection of the sensor to the metal plate, which is then used as a return conductor or second electrical connection.
  • the sensor should be resistant to scale, so as not to be attacked or damaged by the high temperatures in the heating zone. Furthermore, it is advantageous if the material of the sensor has no Curie point. Otherwise, distortions of the measurement results could occur.
  • a noble metal temperature measuring resistor is, for example, a PT 100 or a PT 1000.
  • the noble metal Temperaturmeßwiderstand can be exchanged for the ceramic part of the rod controller.
  • the outer tube of the rod controller may be formed as a sensor and as a holder for the noble metal Temperaturmeßwiderstand.
  • the invention also comprises a hob with a plurality of radiant heaters, wherein at least one of the radiant heaters, advantageously all, can be formed in the manner described above.
  • a necessary sensor electronics for the evaluation of signals of the sensor should of course be present. It may be formed as described, for example, in DE 196 03 845 A1, the content of which is made explicit reference to the content of this description
  • Figures 1 and 2 show in cross section a radiant heater 11 according to the invention, which is formed substantially in the usual manner.
  • a radiant heater 11 which is formed substantially in the usual manner.
  • a metal plate 12 with laterally raised edge 13 a flat insulating body 14 is arranged with a peripheral edge piece 15.
  • On the insulating body 14 of the heating element 16 of the radiant heater is laid, for example in meandering turns, see Fig. 2.
  • Right is attached to the metal plate edge 13, a connection block 18 of a rod controller.
  • further electrical connections 19 are provided for the heating conductors 16 of the radiant heater 11.
  • the tube 21 of the rod controller of the connecting block 18 extends across the entire radiant heater 11 or metal plate 12 away. With its left end 22 it is stored in the insulating edge piece 15 or even stands a little bit beyond.
  • the metal tube 21 of the rod regulator is designed as a pot detection sensor.
  • the sensor 21 extends over the entire metal plate 12 or radiant heater 11 and thus covers in any case a heating zone 17 formed by the heating conductors 16.
  • the electrical contacting of the tube or sensor 21 takes place in the right-hand area on the one hand by the fact that the sensor is connected either directly to the metal plate 12 and its edge 13 via the attachment of the rod controller as a ground. Since the sensor 21 passes through the metal plate edge 13, can be provided as an alternative possibility, an electrical contact, for example by simple concern or corresponding resilient contact means.
  • the electrical contacting of the left other end of the sensor 21 takes place at the end 22, which, as can be seen in Fig.
  • a attached to the end 22 piece of flexible metal strand 24 is guided to a male lug 25 of a connecting block 27.
  • the connecting block 27 is attached to the metal plate edge 13 and is made in the usual way of insulating, preferably ceramic material. It is important that the sensor end 22 has no contact with the metal plate edge 13 in the region of the opening. For this purpose, the breakthrough may be formed sufficiently large, since a bearing protection of the end 22 anyway by means of the penetration through the insulating edge 15 takes place. Another, even more reliable method is to isolate the breakthrough or a hole or cutout with a kind of electrically insulating shell, such as plastic or ceramic, inwards. In this way, a storage of the sensor end 22 also take place on the metal plate edge 13.
  • the metal plate edge 13 in turn is connected via a further flexible metal wire 28 with the second plug connection lug 26 of the connecting block 27.
  • the contacting of the sensor 21 takes place at one end via the sensor end 22 and the metal strand 24. At the other end, it takes place via the metal strand 28 and the plate rim 13.
  • the connection lug 26 could be connected directly to the metal plate 12 or even be bent out of this.
  • a similar radiant heater 111 is shown with a metal plate 112, a metal plate edge 113, an insulator 114 and two annular edge pieces 115a and 115b.
  • the inner edge piece 115a divides the heating zone via the heating conductors 116 into an inner heating zone area 117a and an outer heating zone area 117b.
  • a rod regulator 130 is shown in Fig. 4 in excerpts and corresponds to a conventional rod controller to protect against overtemperature, but here has no connection with the sensor function.
  • a leaf spring 131 is screwed or riveted, which protrudes with its long resilient leg at an angle of about 20 ° from the metal plate edge 113.
  • a sensor wire 121 is fixed, wherein the attachment is electrically conductive.
  • the sensor wire 121 runs across the radiant heater 111 in each case through corresponding cutouts 133 in the edge pieces 115a and 115b, wherein it covers the heating zone regions 117a and 117b.
  • connection block 127 is attached, which corresponds to that of FIGS. 1 and 2.
  • the sensor wire 121 is directly on an upwardly projecting Section of a plug-in lug 125 mounted in the connecting block 127 such that it is held straight by the leaf spring 131 by tension.
  • the other plug connection lug 126 is connected to the metal plate edge 113 by means of a flexible metal strand 128 and thus to the sensor 121 via the leaf spring 131. In this way, the sensor 121 is contacted via the two plug connection lugs 125 and 126 in a single connection block 127.
  • connection block 27 or 127 from a connection cable can be performed to a corresponding cooking vessel detection electronics. This can be combined with other electronics for controlling the radiant heater or an entire hob.
  • a thicker wire possibly not flexible, can be used.
  • the leaf spring 131 corresponding spring means can be used for attachment to at least one end.
