Definitions

  • the invention relates to a heating device for heating a medium, in particular a liquid, as well as an electrical appliance with a flow channel for a medium or a liquid.
  • a corresponding heating device which can be designed both as a flat support plate and as a flow heater.
  • the temperature sensors in flat conductor technology or thick film technology are applied to the carrier. Since the heating conductors in thick-film technology are also applied to the carrier, but of a different material, two coating steps are necessary.
  • the invention has for its object to provide an aforementioned heating device and an electrical appliance provided therewith, with which problems of the prior art can be avoided and in particular a simple and reliable construction of a heater for safe and reliable operation can be achieved.
  • the heating device heats the medium or a liquid either in the flow or in the by-pass or it may also be a heating of a standing medium in the manner of a hotplate, for example in a saucepan.
  • the heating device has a carrier, wherein heating conductors are applied to the carrier and at least one first and one second temperature sensor are arranged on the carrier.
  • the carrier may be formed as is generally known, for example of insulating material such as ceramic or the like, alternatively made of metal or steel with an insulating layer thereon.
  • a first temperature sensor is arranged close to the heating conductor, whereby, in particular, the heating conductor temperature should be monitored as directly as possible.
  • a distance may here be less than twice the Schuleiterbreite, advantageously even less than a whole Schuleiterbreite, or be about half Schuleiterbach.
  • Another measure of the distance between the first temperature sensor and the heating conductor can advantageously be related to the thickness of the carrier instead of the heating conductor width, that is to say which path the heat flow from the heating conductor has to the medium into the medium and to the first temperature sensor as the heat cross conduction in the first Carrier.
  • the distance between the first temperature sensor and the heating conductor can advantageously be less than ten times the thickness of the carrier, advantageously less than five times or even only about three times the thickness of the carrier. A sufficient electrical isolation distance must of course be observed.
  • the second temperature sensor has a greater distance from the heating conductor than the first temperature sensor, wherein the two temperature sensors do not necessarily have to be arranged close to one another or it does not necessarily have to be the same point of the heating conductor in the vicinity of which the two temperature sensors are arranged.
  • the distance of the second temperature sensor to the heating conductor more than twice the Schuleiterbach or even more than three times the Schuleiterbreite, for example, three to five times.
  • this distance may be designed so that it is greater than twice the distance of the first temperature sensor from the heating conductor, advantageously about three to five times.
  • the thickness of the carrier can be used as another measure of the distance between the second temperature sensor and the heating conductor, so that a distance to the heating conductor can be greater than fifteen times the thickness of the carrier. More preferably, it is greater than thirty times the thickness of the carrier, or about thirty to fifty times the thickness of the carrier.
  • the first temperature sensor Due to these different distances of the two temperature sensors to the heating conductor can be detected with the first temperature sensor, which is just very close to the heating element, especially the Schuleitertemperatur. Thus, in particular, an undesirably high temperature can be detected and corresponding countermeasures can be initiated, for example, switching off the heating device or reducing the electrical power. Due to this small distance, the temperature at the first temperature sensor is also essentially influenced by the heating conductor and less by the environment or by the medium to be heated due to the aforementioned short paths for the heat flow.
  • the second temperature sensor in turn is further away from the heating element, so that its temperature is essentially determined by the medium to be heated.
  • the aforementioned distances between the second temperature sensor and the heating conductor are generally considered sufficient, in particular if the medium is a liquid, so that the heating conductor temperature has no direct influence on the temperature measured at the second temperature sensor. Especially in the Indication of the distances with respect to the thickness of the carrier, this becomes clear.
  • the two aforementioned temperature sensors are provided on the heater and no further.
  • a further temperature sensor could be provided such that the second temperature sensor and this further temperature sensor are as far apart as possible in a flow direction of the medium. From this, a heating of the medium flowing through can be determined or a heat flow introduced by the heating device.
  • the temperature sensors can be PTC resistors.
  • the temperature sensors are designed as NTC resistors, in particular with the best possible linear characteristic in a range of 0 ° C to 200 ° C or 300 ° C.
  • the first temperature sensor and the second temperature sensor or all temperature sensors are identical.
  • At least one of the temperature sensors is designed as SMD components, advantageously both.
  • the small design requires little space on the carrier. Due to their low thermal mass can be done very good and fast temperature detection. They can also be easily soldered onto the carrier in SMD technology and are responsible for the best possible temperature transfer both by the soldering and the typical SMD design. A temperature transfer can here by thermal paste odgl. be improved.
  • one or the temperature sensors are not fixed or insoluble on the support are applied, so not as described above are soldered on it.
  • they can be pressed or applied against the carrier by another holding device and can also be electrically contacted by means of this holding device.
  • a step of soldering the temperature sensors on the carrier can be omitted.
  • the first temperature sensor may be elongated and extend substantially parallel to a longitudinal course of that heating conductor, to which it has the smallest distance.
  • This arrangement of the temperature sensor has the advantage that then the heating current coming from the heating conductor, so to speak, transversely hits the temperature sensor and this is heated as evenly as possible over its length. This improves the measurement accuracy and the claim speed of the first temperature sensor.
  • this first temperature sensor can point to any area of the heating conductor or be very close to it.
  • it is an area of a loop of the heat conductor.
  • the heating conductor can advantageously meander-shaped or run in loops on the support.
  • the bends of the loops can be designed so that either the heating conductor rotates with approximately its width.
  • the loop can stop and their ends connected by means of a very good electrically conductive contact bridge or be contacted. This is known from the prior art, see the EP 1905271 B1 ,
  • the second temperature sensor is arranged in the region of such an aforementioned bend or loop, ie that the heating conductor comes closest to the second temperature sensor with such a bend or loop.
  • This has the advantage that here the generated heating power is slightly lower and thus the second temperature sensor once again a little less exposed to the direct temperature influence of the heat conductor.
  • the heating element is advantageously formed from a resistance material in thick film technology.
  • a thickness may be at least 5 ⁇ m, advantageously at least 20 ⁇ m to more than 50 ⁇ m.
  • the width of a heat conductor is advantageously approximately equal in its longitudinal course and can be between 2 mm and 10 mm, advantageously about 5 mm to 7 mm. With a parallel connection of the heating conductors, the width can be even lower.
  • the electrical appliance according to the invention has a flow channel for a medium or a liquid, in particular water.
  • a heating device according to the invention or it forms this flow channel at least in part.
  • the heating device is tubular with a tubular support. But it can also be a partial tube.
  • the medium then flows through the heater.
  • Heating conductor and temperature sensors are arranged on the outside of the heater or the carrier, so that they do not come into contact with the medium or the liquid and are also easier to reach for electrical contact.
  • the second temperature sensor is arranged in the flow direction of the medium behind the first temperature sensor.
  • an electrical appliance according to the invention may have a heating device according to the invention with a flat or plate-shaped carrier, for example as a cooking appliance or hob for setting up a pot or other container.
  • a heating device has a tubular design, then it is advantageously installed in the electrical appliance such that at least one of the temperature sensors is arranged in a vertically uppermost region of the heating device. This is particularly advantageous the first temperature sensor near the heating element. If there is a medium or liquid in the flow channel, and in turn air bubbles or air inclusions, then they are usually in this uppermost area, if their location can even be stated. Since then due to the air bubbles, the heat loss through the medium from the heater is not so good, there is a risk of local overheating of the heater or the heating, which can then be detected very well and very quickly by this temperature sensor arranged here.
  • the second temperature sensor for detecting the temperature of the medium or of the liquid itself can on the one hand also be arranged in a vertically upper or the vertically uppermost region. Alternatively, the second temperature sensor can be provided further below, in particular for the reason that, if possible, the temperature of the medium should be measured, regardless of such air inclusions or even with them.
  • a heater 11 according to the invention is shown with a tubular support 12 in the form of a metal tube.
  • heating conductors 14 are applied in variously extending webs with a width of about 3 to 5 mm and an aforementioned thickness.
  • the two left heat conductors 14 form with free ends a bend 16 and a loop therof, wherein the free ends are connected to each other by means of a contact bridge 17, as is basically known in the aforementioned prior art.
  • the Both right heat conductor 14 are guided to contact fields 18. At these contact fields 18 can take place in principle any contacting, for example as in the aforementioned EP 1152639 A1 known. Alternatively, individual plug connection lugs can be soldered or welded here.
  • first temperature sensor 20 and a second temperature sensor 22 are arranged on the outside of the carrier 12.
  • the temperature sensors 20 and 22 are formed as SMD components and soldered to corresponding solder pads 23.
  • An electrical contact is made via contact pads 24, wherein also here for electrical connection, for example, plug connectors or the like. can be soldered.
  • the distance d1 between the first temperature sensor 20 and the heating conductor 14 is quite small and is in particular approximately in the range of Schuleiterbach itself. Furthermore, the longitudinal course of the first temperature sensor 20 is parallel to the longitudinal course of the heating conductor 14 in this area. In practice, this may be a distance of about 5 mm, and with an exemplary thickness of the carrier of 0.7 mm, the distance d1 is about seven times the thickness of the carrier 12, but may just as well be slightly more or less.
  • the distance d2 of the second temperature sensor 22 to the heating conductor 14, in particular in the region of the bend 16, is considerably greater than the distance d1, namely approximately three times as large.
  • the distance d2 is approximately three times the width of the heating conductor or approximately twenty times the thickness of the support 12.
  • the second temperature sensor 22 is generally removed in one direction from the heating conductor 14 or a bend 16, respectively. that it does not come closer to other heated areas or heating conductor of the heater 11.

  • the longitudinal direction of the first temperature sensor 120 transverse to the longitudinal direction of the heat conductor 114 in its vicinity. The distance is very low here and is above all less than half the width of the heating conductor.
  • a second temperature sensor 122 is also formed in SMD technology and attached to solder pads 123. Its distance from the heat conductors 114 is significantly greater than that of the first temperature sensor 120, and slightly more than twice the Schuleiterbach. The thermal conduction in the carrier 112 up to this point is considerably further than the first temperature sensor 120, so that the temperature measured by it is determined less by the heating conductors but rather by the medium on the carrier.
  • the temperature sensors 120 and 122 are connected to contact pads 124 for electrical contacting as described above.
  • the carrier 112 may here be a ceramic plate or a metal plate with a corresponding insulating layer thereon.
  • the heat conductors are in the embodiments according to the Fig. 1 and 2 applied in thick film technology, as is known per se from the prior art.
  • FIG. 3 schematically shows how a heater 211 is traversed by a tubular carrier 212 by a liquid 213.
  • heating conductors 214 are indicated at the top and bottom.

  • the support arm 226 is biased by its formation or attachment to the support 212 in the direction of the carrier 212 so that it presses with the force F on this.
  • the second temperature sensor 222 is firmly, permanently and reliably applied to the outside of the carrier 212 and is thus arranged there according to the concept of the invention.
  • Direct application also provides good heat transfer from the carrier 212 to the temperature sensor 222.
  • the advantage in such an arrangement compared to a fixed arrangement of the temperature sensor on the carrier according to the Fig. 1 and 2 lies in the more flexible design, especially no corresponding soldering steps or the like. be performed on the carrier after the coating process for the heating element 214th
  • FIG. 4 an inventive electrical appliance is shown as a dishwasher 30, in the interior 32, a flushing arm 33 rotates.

  • the position of the first temperature sensor 20 may be shown at the uppermost point of the heating device 11 or the water supply formed by it. This applies both to a heating device 11 behind a pump 36 and above all to a heating device integrated in a pump according to the aforementioned DE 102011003464 A1 , Are here in addition to promotional water still contains air bubbles that can greatly reduce the heat loss with the risk of overheating of the heating element 14, these bubbles are usually just at a high or at the top point.

  • the temperature sensor 20 as well as the heater 11 in total or the heating conductor 14 and also the pump 36 is connected to a controller 37. If the controller 37 detects an inadmissibly high temperature at the heating device 11, in particular also on the basis of the first temperature sensor 20, it can reduce or completely switch off the supplied heating power.

  • the two temperature sensors are identical.
  • the course of the resistance R over the time t of the first temperature sensor 20 is dash-dotted and that of the second temperature sensor is dashed.
  • the absolute difference between the two resistance values is shown in solid lines. Since the first temperature sensor 20 due to its arrangement close to the heating element 14 always measures a higher temperature, its resistance value is always slightly lower due to the formation as an NTC resistor and decreases faster.
  • the heater 11 is turned on and starts to heat.
  • the resulting increase in temperature causes a slow decrease of the resistance values for the two temperature sensors.
  • the difference between the resistance values decreases slightly.
  • time t2 after just under 150 seconds, in the example case of dry-running shown here, there is no longer sufficient water in the heating device 11, starting in the uppermost region. So not enough heat is removed and there is a significant warming. This is shown by the rapid decrease in the resistance values of the two temperature sensors. From the time t3 at slightly more than 160 seconds begins a so-called abnormal or unwanted operation. From here, the difference between the two resistance values increases sharply, so that a controller 37 advantageously evaluates above all the course of this difference, since the changes are the most significant and characteristic here.
  • the controller 37 has not only detected the changes in the resistance values, but also concluded that there is an abnormal operation, and turns off the heater 11 completely.
  • the temperature rises on the heating element or on the heater no longer on, but drops relatively quickly again, which is expressed by an increase in the resistance values of the two temperature sensors. Since now no more heat is generated via the heat conductor, which arrives at the first temperature sensor stronger or causes a stronger warming there, the curves for the resistance values of the two temperature sensors rise rapidly towards each other, so that the difference curve quickly goes close to zero.
