Definitions

  • the invention relates to a heating device with at least two series-connected thermoelectric modules.
  • thermoelectric modules can be arranged as a heating device, which are electrically interconnected in series. If one of these modules fails, the entire heater fails.
  • thermoelectric modules may be formed, for example, as Peltier elements, which are used in a Peltier heat pump of a clothes dryer.
  • a household appliance with an electronic control device which is switchable in the event of a defect of a functional component to a so-called emergency operation, is off DE 100 39 444 A1 known.
  • thermoelectric module It is an object of the present invention to provide a heater whose failure can be prevented when a thermoelectric module fails.
  • a heating device which has the features according to claim 1
  • a domestic appliance which has the features according to claim 7.
  • a heating device comprises at least two series-connected thermoelectric modules. At least one thermoelectric module, a circuit arrangement is connected in parallel, which is designed such that in the event of a fault of the thermoelectric module, electrical current flows through the circuit arrangement.
  • the further operation of the heating device can be ensured even if the thermoelectric module fails. Even with a failure of one or more thermoelectric modules of the heater can thereby the Power supply of the other series-connected thermoelectric modules are guaranteed and thus the operation of the heater can be maintained.
  • each thermoelectric module is connected in parallel with a separate circuit arrangement. Regardless of which or how many of the thermoelectric
  • a circuit arrangement preferably has only one electronic component.
  • the circuit arrangement can be made very simple and yet effective.
  • a component-minimized and therefore cost-minimal design can be ensured.
  • the circuit arrangement preferably comprises a resistor, in particular an NTC resistor. If a thermoelectric module fails, the electrical current could then flow through the NTC resistor to the next thermoelectric element. Although this would result in a slight reduction in performance of the device, but the basic function would continue to be guaranteed despite the defect of one or more of the modules.
  • a circuit arrangement has a switch.
  • the switch can be designed as a temperature switch or as a current-dependent switch.
  • a temperature switch can be achieved that closes in case of a possible defect of an associated thermoelectric module by the temperature reduction of this temperature switch and thus short-circuits the associated thermoelectric module. This also allows the current flow to the downstream thermoelectric module can be ensured and the functionality of the heater can be maintained.
  • thermoelectric module as a current-dependent switch is provided that this closes, if no current flows through the thermoelectric module.
  • the invention further relates to a domestic appliance for the care of items of laundry, in particular a clothes dryer or a washer-dryer, with a heating device according to the invention or an advantageous embodiment thereof.
  • a domestic appliance for the care of items of laundry, in particular a clothes dryer or a washer-dryer, with a heating device according to the invention or an advantageous embodiment thereof.
  • thermoelectric modules are designed as Peltier elements and assigned to a Peltier heat pump of the domestic appliance.
  • thermoelectric modules 2 and 3 are designated by way of example in greater detail.
  • the thermoelectric modules 2, 3 are formed as Peltier elements and associated with a Peltier heat pump of the tumble dryer.
  • thermoelectric modules 2, 3 of the heater 1 are connected in series with each other.
  • a respective circuit arrangement is connected in parallel.
  • thermoelectric module 4 is connected in parallel and the thermoelectric module 5, a further circuit arrangement 7 is connected in parallel.
  • the two circuit arrangements 6 and 7 each have only one electronic component.
  • the circuit arrangement 6 comprises an NTC resistor 61 and the circuit arrangement 7 likewise has an NTC resistor 71. If, for example, the thermoelectric module 4 fails, the electrical current is connected via the circuit arrangement 6 and thus via the NTC resistor 61 to the downstream circuit thermoelectric module 5 passed.
  • FIG. 3 Another version is in Fig. 3 shown. Also there is an enlarged partial section of the illustration according to Fig. 1 shown, in which in the circuit arrangements 6 and 7 instead of the NTC resistors 61 and 71 in turn in each case only a single component is connected. Thus, in the embodiment according to Fig. 3 Both the circuit arrangement 6 and the circuit arrangement 7 a temperature switch 62 and a temperature switch 72. If in this embodiment, for example, the thermoelectric module 4 fails, then a temperature reduction occurs, which causes the temperature switch 62 closes and the current through the circuit 6 and thus also via the closed temperature switch 62 to the downstream thermoelectric module 5 flows.
