Definitions

  • the invention relates to a tumble dryer comprising a Peltier heat pump with a Peltier module, which comprises at least one series arrangement of Peltier elements, each series arrangement can be acted upon by a DC voltage, and a circuit arrangement for operating the Peltier module.
  • a dryer with a Peltier module is in document DE 20 202 782 U2 disclosed.
  • Peltier element in structure and function is known, which has the structure described above.
  • the half elements of this Peltier element are columnar or cuboidal and consist of doped semiconductors as materials.
  • the semiconductors are in particular bismuth telluride, and a p-type doped semiconductor and an n-type doped semiconductor are used.
  • a half element of the p-type doped semiconductor and a half element of the n-type doped semiconductor are each connected to one side via a printed circuit board, also referred to as a metal bridge, and at another side, which is opposite to said one side , connected in each case via a further printed circuit board with a further half-element or a connection contact for connection of the Peltier element to an electrical network.
  • a printed circuit board also referred to as a metal bridge
  • the DE 1 410 206 A is a washing machine, in which laundry not only washed, but also can be dried.
  • an electric heating device for heating an air stream used for drying laundry and a simple heat exchanger for cooling the heated Air flow may be provided after applying the laundry, but the heater and the radiator may also belong to a heat pump.
  • the heat pump device may be a heat pump device which operates with Peltier elements for use of the thermoelectric effect.
  • the series arrangements must be subjected to DC voltages of different magnitudes to occupy an operating point which is suitable for the operation of the Peltier module in the context of a Peltier heat pump for a tumble dryer.
  • the DC voltage is generated by rectifying the mains voltage, in particular 230 volts AC, in a mains rectifier having a conventional rectifier design.
  • the number of Peltier elements and the manufacturer of the Peltier elements are selected so that they are adapted to this rectified mains voltage optimized.
  • the number of Peltier elements and the manufacturer type are selected such that the Peltier elements of the series arrangement are operated by applying the rectified mains voltage to the series arrangement at an operating point which is suitable for the Use of the Peltier module in a Peltier heat pump is at least suitable and is preferably optimized.
  • the invention makes it possible to operate the Peltier module indirectly with mains voltage.
  • mains voltage in particular, in the context of a tumble dryer, which is connected to the mains voltage, this represents a particularly simple way of providing a DC voltage.
  • a switch is provided with two positions, at its first position, the rectified mains voltage of the Peltier module acted upon, and at its second position, the rectified mains voltage is not applied to the Peltier module, but the Peltier module is connected to another consumer.
  • the switch takes account of the fact that another consumer in the tumble dryer can use an electrical voltage that arises due to the sea-bake effect when the Peltier module is exposed to a temperature difference between the associated heater and the associated cooler without connection of an external electrical voltage.
  • a preferred example of this is the interior lighting of the tumble dryer: If the tumble dryer is opened, the Peltier heat pump is switched off in any case beforehand. Interior lighting and Peltier module are thus not in competition with each other, but are operated alternately.
  • the switch can be controlled by a drive unit. This may for example be connected to the main controller of the tumble dryer, so that they z. B. detects whether the dryer is opened or not to make the said switchover to the interior lighting can.
  • the Peltier module which is separate from its supplying DC voltage, is used as a sensor: From the voltage generated by itself (as explained above), a temperature difference between the heating and cooling component of the Peltier module can be determined and the electrical resistance of the Peltier module results its own operating temperature.
  • the Peltier module is used accordingly in several respects as a temperature sensor, with suitable connections to the drive unit being provided for the purpose of detecting corresponding measured variables.
  • the control unit can control the switch at least optionally as a function of the temperature and thus repeating periodically make appropriate measurements. This makes it possible to introduce a control in which the Peltier module is turned off when the temperature leaves a critical area.
  • the control temperature depends on the temperature sensor data and the dimensioning of the control circuit.
  • a switch can be controlled, which can interrupt the entire voltage supply, for example because it is located on the AC side of the power rectifier and can interrupt the AC power supply. This then takes into account the fact that the other consumers do not need the voltage during the temperature control of the Peltier module in the meantime, so that the rectifier can be completely turned off in the context of the scheme.
  • the temperature control of the type mentioned serves to regulate the temperature in a certain range.
  • an over-temperature protection can be provided. This can be made much more direct than it takes place via the intermediate path of a special temperature sensor.
  • a thermal switch can be coupled. If the Peltier module (at the coupling point) exceeds a certain temperature, the thermal switch switches.
  • the thermal switch may be disposed on the DC side, it is preferable that it is disposed on the AC supply side to the power rectifier, so that it interrupts the AC power supply completely in the case of overheating.
  • a buffer capacitor may be arranged downstream.
  • the charging current on the buffer capacitor is preferably limited by a charging current limiter (for example of the NTC type).
  • the corresponding interconnection results in a logical manner such that the buffer capacitor is connected in parallel with two outputs of the mains rectifier, and that the charging current limiter is arranged in the current path between a terminal of the mains rectifier and a terminal of the buffer capacitor.
  • FIG. illustrates the circuit diagram of the circuit arrangement according to the invention.
  • FIG. schematically illustrates a Peltier module 1, which is to serve for use in a Peltier heat pump for a tumble dryer.
  • the Peltier module comprises Peltier elements 2 connected in series, although twelve Peltier elements are shown here, but the Peltier module need not be fixed to the number twelve.
  • the number of Peltier elements and the operating values of the Peltier elements i.e., the manufacturer type of Peltier elements
  • the Peltier element array can be operated with a voltage that results when the line voltage is rectified.
  • the mains voltage of 230 volts AC (230 Vac) is initially provided, wherein here the connections L and N are shown schematically.
  • the AC voltage is rectified by a mains rectifier 3, which has a conventional construction of a rectifier.
  • a buffer capacitor 4 is provided, which is connected in parallel with the DC-side terminals of the mains rectifier 3.
  • NTC resistor i.e., a negative temperature coefficient resistor
  • Thermally coupled to the Peltier module 1 is a thermal switch 6. At an excess temperature of the Peltier module 1, the thermal switch 6 switches on the AC side of the power rectifier 3, cuts off the AC power supply and thus turns off the Peltier module 1.
  • the temperature control can also be designed somewhat more precisely.
  • a temperature sensor 7 is provided on the Peltier module 1 at a predefined location. This supplies electronic measured values to a relay drive unit (relay drive circuit) 11.
  • a relay drive unit relay drive circuit
  • About the Relaisan Kunststoff Vietnamese 11 can also be a AC-side switch 9 are actuated, d. H. the entire Peltier module 1 are turned off.
  • the Relaisan horr Vietnamese 11 has as a further input a DC voltage signal from the main controller of the tumble dryer.
  • the Peltier module 1 can therefore also be switched off indirectly via the main control by means of the relay drive circuit 11 and the switch 9.
  • a switch 10 (relay) is provided.
  • the rectified mains voltage can also be separated from the Peltier module 1 and the Peltier module 1 can be switched to an interior lighting 12 of the tumble dryer.
  • the interior lighting 12 four light-emitting diodes and an additional resistor connected in series to the light-emitting diodes are illustrated schematically here.
  • the change-over switch 10 can also bring about a switchover to other consumers, such as further sensors, measuring devices, controls, display elements, etc .; Such measuring devices are expediently integrated into the main controller 11 of the tumble dryer.
  • the changeover switch 10 is also controlled via the Relaisan Kunststoffnik 11, so it can be optionally regulated depending on the temperature measured by the temperature sensor 7.
  • the changeover switch 10 By switching the Peltier module 1 is separated from the DC voltage, whereby the temperature is lowered again. If the temperature measured by the temperature sensor 7 drops below a certain limit value, the drive unit 11 becomes active again and switches the switch 10 again, so that the Peltier module 1 is again connected to the rectified mains voltage.
  • a throttle 8 for power factor correction (Power Factor Correction, PFC) is connected upstream of the rectifier 3.
  • the Peltier module 1 has operating values which are optimized by suitable choice of the number of individual Peltier elements 2 and by suitable selection of this type in such a way that it can be operated with a rectified mains voltage.
  • the operating point is optimized for the operation of the Peltier module 1 for use in the context of a Peltier heat pump in providing the rectified mains voltage.
  • the switch 10 may be provided, which switch 10 thus provides the voltage in the Peltier module 1 caused by the Seebeck effect usable voltage for other consumers.
