Definitions

  • the invention relates to a clothes dryer according to the preamble of claim 1.
  • Tumble dryers with, for example, a moisture sensor device are known. For signal transmission, this is connected to a control of the tumble dryer on the one hand via the storage of the laundry drum. The other contact takes place via a contact track applied to the outside of the drum. A resilient grinding arm rests on this contact path and forms the other signal-transmitting connection.
  • This is considered to be disadvantageous because, on the one hand, the mechanical outlay is relatively large. There are also disturbing noises. Eventually, annoying and dirty grinding abrasion can occur. This should be avoided.
  • the invention has for its object to provide an above-mentioned clothes dryer in which the problems of the prior art can be avoided, in particular the disadvantages of signal transmission by means of contacting grinder should be avoided.
  • a tumble dryer is also understood below to mean a combined appliance with a tumble dryer function, for example with a washing machine.
  • Advantageous as well as preferred Embodiments of the invention are the subject of the further claims and are explained in more detail below. The wording of the claims is made the content of the description by express reference.
  • the drum has a sensor device with which a physical property or a value in the drum, for example laundry, can be determined.
  • this can be a moisture sensor device with which the degree of moisture in the laundry can be determined.
  • a degree of contamination or a temperature can also be determined.
  • the sensor device is connected in a signal-transmitting manner to a control of the clothes dryer, for example a program control.
  • This signal-transmitting connection is designed to be contactless, which also means wireless or contactless.
  • Such a contactless signal transmission has the advantage that mechanical components can be saved.
  • contactless signal-transmitting connections can bridge variable distances in a certain area, they are less dependent on structural requirements. This enables simplified production and greatly simplified and improved variant formation.
  • connection for transmitting the signals of the sensor device advantageously has at least one signal transmission device and at least one receiver device which is advantageously associated with the signal transmission device. Based on this, there are various options for such a connection.
  • a signal-transmitting connection is the use of light signals. This is advantageously done in the IR range.
  • a plurality of light transmitters can be provided along a circumferential circumferential line of the drum with either one or more receivers assigned to this path.
  • a definition of a spatial assignment is necessary at least to a certain extent. In turn, the transmission is relatively simple and trouble-free.
  • a characteristic value of a signal transmission device can be queried electromagnetically in order to establish the signal-transmitting connection.
  • Such a characteristic value can be suitable, for example, for determining the degree of moisture.
  • it can be directly changeable by the degree of moisture in the laundry itself.
  • signal processing means could be saved.
  • it is the characteristic value of a moisture-sensitive sensor of an element. This changes depending on the degree of moisture in the laundry.
  • the moisture level can be queried directly and in a simple manner.
  • the signal transmission device and the receiver device can meet each other on the revolution of the drum or run past each other. Depending on the type of signal transmission selected, this can be done at a short distance from one another. This reduces the risk of interference. Furthermore, the necessary transmission services are lower.
  • a signal can be transmitted continuously by the signal transmission device, in particular in the case of a radio connection.
  • the signal can either be sent regularly. Alternatively, it can be matched to the number of revolutions or the rotational speed of the drum. It is thus possible for the signaling device to always transmit at least at the same point, possibly also at further points.
  • the signal itself can be said that, according to one embodiment of the invention, it can indicate that a certain value of the physical property, for example a certain degree of moisture, has been reached.
  • a certain value of the physical property for example a certain degree of moisture
  • This can be done as a digital signal with two possible values, so to speak. For example, this can be such that a certain degree of moisture is specified. If this is still exceeded, the signal is zero. As soon as it is reached or fallen below, the signal changes to one. The change can also take place in reverse. So the signal can be kept simple on the one hand.
  • the information necessary for a control can be contained in it, for example to stop the drying process.
  • the sensor device can have its own energy source. This means that the transmitters in particular can be operated. It is possible to use a battery or a rechargeable energy store as the energy source. This could be an accumulator, but it could also be a storage capacitor.
  • the energy source can be a generator. It can use the rotation of the drum and the sensor device together with the energy source itself.
  • the energy source can have a coil in the outer region of the drum or its storage. Magnetic fields are provided on the housing in accordance with the circumferential path of this coil. These can be generated, for example, by permanently arranged permanent magnets, and also by an electrical coil. By moving the coil past the magnetic fields, electrical energy is transferred into the coil.
  • the sensor device can have signal processing, for example a microprocessor.
  • the signal from a sensor element or the sensor device can thus be processed, for example in digital values in the manner described above.
  • a sensor element there are numerous possibilities for forming a sensor element and / or arranging it on the drum.
  • One way is to element, possibly also the entire sensor device, to be arranged in a projection on the inside of the drum.
  • projections are present as carriers, for example ribs aligned parallel to the axis of rotation, with which the laundry is swirled and loosened up during drying.
  • the sensor element can be designed, for example, to measure a conductivity or an electrical potential between the projection, the laundry to be dried and the other drum.
  • the sensor element can have two sensor surfaces, for example. The conductance or the electrical potential between them can thus be determined. This makes it possible to determine the degree of moisture in the laundry.
  • the energy source in the same projection as the sensor device or the sensor element.
  • a housing with a type of battery compartment can be provided in such a projection, or generally on the inside of the drum.
  • This battery compartment should be accessible from the inside of the drum, for example to change the battery. Furthermore, it should be sealed during operation so that no moisture penetrates which could damage the battery and / or the sensor device.
