Definitions

  • the invention relates to a tumble dryer or washer dryer according to the preamble of claim 1.
  • At least one temperature This can be used to control or regulate a process as a function of the detected temperature.
  • This also includes the inductive heating of the drum, also known as the laundry drum, of a laundry dryer and in particular a washer dryer from the outside.
  • inductive coupling electromagnetic waves are emitted from the stationary housing of the tumble dryer or the washer dryer inwards to the rotating drum, which there, comparable to an inductive hob, lead to inductive heating of the metallic material of the drum.
  • this heating is given off to the laundry to be dried, so that more moisture can be removed from the laundry with the process air than without the additional inductive heating of the drum. This can accelerate the drying process of the laundry and thus shorten the drying process. The stress on the laundry can also be reduced as a result.
  • the drum temperature must be measured and the inductive heating of the drum controlled by adjusting the heating power. This requires a correspondingly accurate measurement of the drum temperature.
  • contactless temperature detection is to measure the temperature of the drum directly by means of an external sensor, for example by means of an infrared sensor.
  • an external sensor for example by means of an infrared sensor.
  • the manufacturing effort and the costs for the device in question are increased. This is particularly the case when a black outer coating of the drum, for example, is required to ensure a functioning temperature measurement.
  • a possibly necessary outer coating of the drum can also change its properties or be damaged over time and thus also impair the reliability of the measurement.
  • the risk of failure is increased or the reliability of the device is reduced, since the sensor fails or can no longer measure correctly. This is due to the fact that infrared sensors that work optically can, for example, easily become soiled, for example by lint, which inevitably occurs during drying.
  • the temperature-dependent change in the conductivity and permeability of the system which is reflected in the decay behavior of the stationary resonant circuit, is also only very small with the usual slightly ferromagnetic drum materials, so that the temperature-dependent change in the frequency measured in the time window of the decay changes only slightly.
  • the DE 199 19 843 A1 describes a one-piece oscillating circuit, the passive components of which are arranged on the moving part of a device.
  • the passive components have a temperature-dependent capacitance and / or a temperature-dependent ohmic resistance.
  • This passive parallel resonant circuit is excited with a variable-frequency electromagnetic field and the absorbed power is measured.
  • the currently absorbed power of the resonant circuit is compared with a reference power, which corresponds to a reference temperature. This allows the current temperature of the movable component to be determined.
  • the variable frequency is generated with a signal generator.
  • the power absorbed by the resonant circuit is recorded with a suitable measuring device for power measurement.
  • the invention thus poses the problem of enabling contactless temperature detection of a rotating drum of a tumble dryer or a washer dryer of the type described at the outset, which can be carried out more precisely and / or more simply than previously known.
  • At least an alternative to the known corresponding possibilities should be created.
  • the present invention relates to a tumble dryer or washer-dryer with a drum which is designed to receive laundry to be dried, and with a housing from which the drum is rotatably received.
  • the tumble dryer or washer dryer is characterized in that the housing has an active oscillating circuit part and that the drum has a passive oscillating circuit part, the passive oscillating circuit part having a temperature-dependent, frequency-influencing component and the active oscillating circuit part and the passive oscillating circuit part being designed to jointly form an oscillating circuit train whose resonance frequency depends on the temperature-dependent, frequency-influencing component on the temperature of the drum.
  • the present invention is based on the knowledge that in this way a resonant circuit or an oscillator can be created whose vibration behavior is temperature-dependent.
  • the resonant circuit can thus be excited to oscillate, which is influenced by the temperature dependency of the temperature-dependent, frequency-influencing component on the part of the passive resonant circuit part.
  • the passive resonant circuit part provides feedback to the active resonant circuit part as a function of the temperature of the Drum, so that the temperature of the drum can be deduced from the feedback or the change in the oscillation behavior of the active oscillating circuit part compared to the predetermined behavior.
  • the passive oscillating circuit part can be made completely passive, i.e. it can be excited from the outside by the active oscillating circuit part.
  • the simplest possible electronic components can be used for the passive oscillating circuit part, which can make it independent of its own electrical power supply.
  • the properties described above can be achieved via the corresponding temperature dependency of the frequency-influencing component.
  • the active oscillating circuit part is connected to a control unit in a signal-transmitting manner and the control unit is designed to determine the temperature of the drum, preferably a drum shell, from a time curve and / or from a frequency curve of the oscillation of the oscillating circuit.
  • the control unit is designed to determine the temperature of the drum, preferably a drum shell, from a time curve and / or from a frequency curve of the oscillation of the oscillating circuit.
  • This can make it possible to evaluate the resonance frequency of the resonant circuit on the part of the tumble dryer or washer dryer in such a way that the temperature of the drum or the drum shell can be determined.
  • this temperature information can be used to control or regulate an inductive heating of the drum or the drum shell.
  • the corresponding relationships that are required to determine the temperature from the behavior of the oscillating circuit can be stored in the control unit for this purpose.
  • the temperature-dependent, frequency-influencing component is so heat-conductive with the drum, preferably with a Drum shell, connected, so that the temperature of the drum, preferably the drum shell, can act on the temperature-dependent, frequency-influencing component with as little delay as possible.
  • the temperature of the drum can be transferred to the temperature-dependent, frequency-influencing component in a sufficiently heat-conducting manner, so that the temperature dependency of the frequency-influencing component can be viewed as representative of the temperature of the drum.
  • the active resonant circuit part and the passive resonant circuit part are designed to be capacitively coupled to one another.
  • at least one capacitor and preferably several capacitors can be used as capacitive coupling elements, which are arranged with their one electrode part on the part of the active resonant circuit part and with the other opposite electrode part on the part of the passive resonant circuit part.
  • the distance between the housing and the drum can form the air gap of the corresponding capacitor. In this way, a capacitive coupling between the fixed housing and the rotatable drum can be achieved.
  • the active resonant circuit part and the passive resonant circuit part are designed to be inductively coupled to one another.
  • electrical energy can be transmitted inductively.
  • at least one coil with its two coil parts can be arranged in such a way that one coil is arranged on the active oscillating circuit part and another coil is arranged opposite one another on the passive oscillating circuit part.
  • the two oscillating circuit parts can work together by electromagnetic coupling in such a way that the active oscillating circuit part can transfer electrical energy to the passive oscillating circuit part, which can be influenced by the temperature-dependent, frequency-influencing component on the part of the passive oscillating circuit part, as described above.
  • the active resonant circuit part and the passive resonant circuit part are designed to be inductively coupled to one another by means of coils with iron cores.
  • This can enable a comparatively high transfer of electrical energy from the active resonant circuit part to the passive resonant circuit part, since coils with iron cores can generate correspondingly high inductances.
  • coils with iron cores can generate correspondingly high inductances.
  • a temperature dependency of the temperature-dependent, frequency-influencing component of the passive resonant circuit part can have a strong effect on the active resonant circuit part and lead to a correspondingly clear detection of the temperature dependency there.
  • the active resonant circuit part and the passive resonant circuit part are designed to be inductively coupled to one another at least on the part of the passive resonant circuit part by means of a planar coil, preferably also on the part of the active resonant circuit part by means of a planar coil.
  • planar coils can be designed to be comparatively cheap and flat. This can keep the costs of implementing the passive resonant circuit part low.
  • the installation space that is required to implement the passive oscillating circuit part on the drum can thereby be kept comparatively small, in particular in the radial direction.
  • the passive oscillating circuit part as a whole can preferably be arranged on a printed circuit board together with the other electronic components of the passive oscillating circuit part. These can be connected to the planar coil, which can preferably be arranged around the electronic components. This can ensure the most compact and, in particular, flat construction of the passive resonant circuit part.
  • the passive resonant circuit part has an RC resonant circuit with the temperature-dependent, frequency-influencing component, which preferably consists of this.
  • the RC resonant circuit consists of two ohmic resistors and two capacitors, the temperature-dependent, frequency-influencing component being one of the two ohmic resistors.
  • the passive resonant circuit part has an LC resonant circuit with the temperature-dependent, frequency-influencing component, which preferably consists of this.
  • the properties and advantages of an LC resonant circuit can be applied to the present invention and used here.
  • the temperature-dependent, frequency-influencing component is designed as a temperature-dependent, frequency-influencing ohmic resistor, preferably as a frequency-influencing NTC resistor (Negative Temperature Coefficient resistor).
  • NTC resistor Negative Temperature Coefficient resistor
  • the passive oscillating circuit part is arranged radially from the outside on the drum, preferably on a drum shell.
  • the passive oscillating circuit part and the active oscillating circuit part can be arranged on top of one another as well as possible by being aligned radially to one another.
  • there can be a comparatively large amount of installation space for the passive oscillating circuit part in contrast to the two lateral surfaces of the drum or the drum shell.
  • This can also apply to the active oscillating circuit part, which can be arranged radially spaced from the passive oscillating circuit part or from the drum or drum shell in a larger available installation space than on the shell side.
  • the active oscillating circuit part and the passive oscillating circuit part are arranged radially and / or opposite one another in the direction of the longitudinal axis. This can support the implementation of the properties described above.
  • Arranging the passive oscillating circuit part radially from the outside on the drum and in particular on the drum shell can also be advantageous in that the temperature of the drum or the drum shell can be recorded in this way as representative and over a large area as possible.
  • an arrangement of the passive oscillating circuit part on one of the two lateral surfaces on the front side of the drum or the drum shell could ensure a comparatively local temperature detection, which can be less representative of the entire drum than with an arrangement on the radial circumferential surface of the drum or the drum shell .
  • the drum or the drum shell is usually inductively heated radially from the outside, so that the appropriate arrangement of the passive oscillating circuit part means that the temperature is precisely in this area where the inductive heating of the drum or the drum shell can take place detected there and can be used to control or regulate the inductive heating.
  • the active resonant circuit part and the passive resonant circuit part are arranged sufficiently close to one another in order to be able to act together as a resonant circuit.
  • these two oscillating circuit parts are to be placed in such a way that, taking the corresponding boundary conditions into account, a common oscillating circuit can be formed in order to implement the functions described above.
  • the active oscillating circuit part and the passive oscillating circuit part are designed to be sufficiently long in the circumferential direction of the drum in order to be able to act together as an oscillating circuit.
  • This aspect of the present invention is based on the knowledge that the active resonant circuit part and the passive resonant circuit part do not have to be fully configured in the circumferential direction in order to be able to act as a common resonant circuit, even if this is possible. Corresponding costs and installation space can be saved as a result.
  • the active oscillating circuit part and the passive oscillating circuit part are to be designed to be sufficiently extended in the circumferential direction of the drum so that they can at least temporarily interact with one another when the drum is rotating, so that the vibration behavior described above and the development of a temperature-dependent resonance frequency can arise.
  • this must be taken into account when designing and arranging the active oscillating circuit part and the passive oscillating circuit part.
  • a longitudinal axis X extends.
  • a radial direction R extends from the perpendicular to the longitudinal axis X Longitudinal axis X away.
  • a circumferential direction U extends perpendicular to the radial direction R and around the longitudinal axis X.
  • Fig. 1 shows a perspective illustration of the interior of a tumble dryer 1 or a washer dryer 1 with housing 10 and drum 2.
  • Fig. 2 shows a circuit diagram of a capacitive coupling of the resonant circuit 11, 21.
  • Fig. 3 shows a circuit diagram of an inductive coupling of the resonant circuit 11, 21.
  • Fig. 4 shows a circuit diagram of the passive resonant circuit part 21 of the inductively coupled resonant circuit 11, 21.
  • the tumble dryer 1 or washer-dryer 1 in the case under consideration consists essentially of the housing 10, which surrounds an interior of the tumble dryer 1 or washer-dryer 1.
  • the drum 2 which can also be referred to as a laundry drum 2, is arranged in this interior space.
  • the drum 2 is mounted rotatably about its longitudinal axis X in the circumferential direction U and can be driven accordingly (not shown). Laundry can be accommodated in the drum 2 to be dried.
  • an active, device-side oscillating circuit part 11 is arranged on the part of the housing 10. Furthermore, a passive, drum-side oscillating circuit part 21 is arranged on the drum 2 on the drum shell 20 on the radially outer side.
  • the two oscillating circuit parts 11, 21 lie opposite one another in the longitudinal axis X and in the radial direction R in such a way that they can form a common oscillating circuit 11, 21 with one another.
  • the active, device-side oscillating circuit part 11 is connected in a signal-transmitting manner to a control unit 12 of the tumble dryer 1 or washer dryer 1, which can also be referred to as control electronics 12.
  • the active, device-side oscillating circuit part 11 can now emit an electromagnetic oscillation radially inward to the drum shell 20 in order to to couple the passive, drum-side oscillating circuit part 21, which, depending on the rotational movement of the drum 2, is regularly located opposite the active, device-side oscillating part 11. If the two oscillating circuit parts 11, 21 are sufficiently opposite to one another, the active, device-side oscillating circuit part 11 is coupled into the passive, drum-side oscillating circuit part 21, so that an electromagnetic field is formed in the common oscillating circuit 11, 21.
  • the passive, drum-side oscillating circuit part 21 has a frequency-influencing, temperature-dependent component R2, which is connected to the drum shell 20 in a thermally conductive manner. In this way, the temperature of the drum shell 20 has an impact the temperature-dependent, frequency-influencing component R2 on the behavior of the passive, drum-side oscillating circuit part 21. Via the electromagnetic coupling, this has corresponding repercussions on the active, device-side oscillating circuit part 21, which can be detected by the control unit 12. By evaluating the frequency range or the temporal course of the detected vibrations, conclusions can be drawn about the temperature of the drum 2 or the drum shell 20 via a corresponding comparison with stored data from the resonant circuit behavior of the common resonant circuit 11, 21. In this way, contactless temperature detection of the drum 2 or its drum shell 20 can take place. This information can be used, for example, to control or regulate an inductive heating of the drum shell 20.
  • the curves can easily be detected by the control unit 12, which is connected to the active resonant circuit part 11 of the oscillator, and assigned by analyzing a temperature of the drum 2 or its drum shell 20 or its radially outwardly directed upper side. Due to the low speed of a drum 2 and the consequently low path speed of the rotating passive oscillating circuit part 21, there is sufficient time for an oscillation to occur during the coupling phase. One temperature measurement on the drum 2 is therefore possible per revolution of the drum 2.
  • the coupling of the active, device-side oscillating circuit part 11 with the passive, drum-side oscillating circuit part 21 can be carried out capacitively, for example.
  • the passive, drum-side oscillating circuit part 21 on the left side of the illustration of Fig. 2 accordingly has an ohmic resistor R1 and a capacitor C1, which are connected to a frequency-influencing NTC resistor R2 as a temperature-dependent, frequency-influencing ohmic resistor R2, which in this case represents the temperature-dependent, frequency-influencing component R2.

  • inductive coupling can also be used instead.
  • the frequency-influencing NTC resistor R2 is connected to an ohmic resistor R1 and two capacitors C1, C2.
  • This circuit is connected to a further inductive coupling element L2 via an inductive coupling element L1 across the air gap between housing 10 and drum 2.
  • the two inductive coupling elements L1, L2 can also be referred to as coupling coils L1, L2. In the case of the Fig. 3 these can be designed as coils L1, L2 with iron cores.
