Definitions

  • the invention relates to a household appliance for treatment laundry according to the preamble of claim 1.
  • a household machine is from the US-A-5 822 819.
  • Household machines especially washing machines or Tumble dryers are increasingly using electronic Program controls provided that the course of the Regulate program steps.
  • the sequence of program steps is essentially always the same, for example for level measurement, temperature measurement or the like sensors are already provided, the data of which Control of the machine is taken into account.
  • the object of the invention is a household machine propose a more flexible and needs-based Control of the household machine allowed.
  • one according to the invention is distinguished Household machine characterized in that as a sensor Radar sensor is provided. With the help of a radar sensor can additional, previously not recorded operating or Control parameters of the machine recorded and during control the machine.
  • a so-called Doppler radar sensor is advantageous used the frequency differences between an emitted and reflect radiation recorded and evaluated.
  • relative movements between the sensor and the The reflection surface can thus be measured very well.
  • a radar sensor points regardless of whether it is as Doppler radar is used or with the help of standing. Waves works, the advantage of being independent of Contamination or fogging reliable measurement data can deliver.
  • the radar sensor is advantageously behind one Recess in the tub of the machine.
  • This Recess can be made with a non-conductive material, preferably plastic, are sealed.
  • the ones from Radar sensor is used radar or microwave radiation able to use this non-metallic material penetrate so that the interior of the tub with a sensor located outside of it is to be monitored.
  • the Sensor arranged in the area of the filling opening of the machine.
  • Both washing machines and tumble dryers are in the Usually have a hatch attached to the front and is designed as a porthole.
  • This hatch is usually out Glass or artificial glass, so that an inventive Radar sensor can see through the hatch.
  • the radar sensor could also be closed in a metal hatch the inside of the hatch can be incorporated and for example, be covered with plastic.
  • the senor is placed inside the drum. This is mainly of advantage if a metal one Laundry drum is used. This is in the nowadays usual machines where stainless steel washing drums are not used due to the radar radiation can transmit.
  • the arrangement in the interior of the laundry drum can additional data are recorded, e.g. B. the state of Laundry drum or under certain circumstances Statements about the loading condition of the laundry drum to be hit.
  • the radar sensor preferably inside the axis of the Laundry drum arranged.
  • This axis can be used as a hollow tube be formed in which the radar sensor is attached and by a corresponding, again tightly sealed Opening can be directed into the interior of the laundry drum.
  • a plurality of radar sensors are preferably used for different observations used. Also the Use of a radar sensor with different Beam frequencies or different radiation directions an appropriately trained antenna would be conceivable. With different frequencies, according to conventional Radar technology a distance from a reflection surface especially be measured well. With the help of different To some extent, radiation directions result in a local Resolution of the measurement.
  • Waveguides can also be placed outside the washing drum used to get the radar sensor from the observation site to be spaced apart and targeted at the desired location observe.
  • one or more appropriately trained waveguides by a sensor multiple observation points are observed.
  • the radar sensor provided according to the invention can be used for Acquisition of a variety of operating parameters used become. For example, the observation of Vibrations of the laundry drums, for example by one To record unbalance and its extent. Even vibrations of the Vats and / or the entire machine body can with a radar sensor can be detected very precisely and quickly .. The machine can use this data accordingly can be controlled, for example a speed control or the like.
  • the Speed of the drum very reliable and at the same time with other measurements.
  • the Doppler spectrum arises when observing rotating, in particular circular objects depending on the speed one Flank, which stems from the fact that at constant speed at maximum extent of the object to be measured Peripheral speed prevails. This maximum The circumferential speed gives the greatest possible Doppler frequency when observing the rotating Subject so that at this point given Diameter. of the object the speed based on the Doppler spectrum is very easy to grasp.
  • a load control is the Machine with the help of the sensor advantageous to the Control program steps accordingly, for example to the duration of individual washing steps or the spin cycle to match it.
  • the fill level of the Machine with washing liquid using the radar sensor recorded and controlled if necessary.
  • a level can be checked with a radar sensor either directly by reflection on the surface of the liquid or by observing the vibration behavior of the Grip container or other machine parts.
  • various data can be created by secondary effects, for example through effects on the vibration behavior the machine.
  • secondary effects for example through effects on the vibration behavior the machine.
  • a temperature measurement via such would also be conceivable Secondary effects, e.g. B. by detecting the Vibration behavior of a test body or by detection of temperature-dependent linear expansion.
  • a spinning process can e.g. B. not only in terms of Speed, but also in terms of imbalance caused vibrations are analyzed in detail. Also the amplitude of the vibrations or their course can are recorded, for example, the moisture content of the Laundry or the condition of machine components too determine. The moisture content can be immediate or secondary effects such as droplet size or changes on a test specimen, etc.
  • Temperature control is an advantage.
  • the temperature measurement can here again with a radar sensor according to the invention be made.
  • temperature-dependent secondary effects for example via the Vibration behavior, changes in length or the like in addition to an immediate detection of the machine interior be used. That would also be for temperature detection Detection of state parameters of a test specimen as well conceivable, such as for recording any other measured variables. For example, the location you want Temperature measurement appropriate reflection elements attached that are detected by the sensor.
  • FIG. 1 shows a schematic cross section by a washing machine with the sensor according to the invention.
  • the household machine 1 comprises a Machine housing 2, in the interior of which a tub 3 is arranged is. Inside the tub 3 is a laundry drum 4 rotatably mounted.
  • the laundry drum 4 in the present case comprises one Hollow shaft 5 with radial passages 6, 7.
  • the tub 3 has a recess 8, which with a Plastic insert 9 is closed. Outside of Vat 3 is a radar sensor 10 behind the insert 9 appropriate.
  • the radar sensor 10 is capable of using the insert 9 to illuminate the inside of the tub 3 and to record corresponding machine parameters.
  • the interior 11 of the hollow shaft 5 is through suitable dimensioning as a waveguide.
  • the Interior 11 is in a manner not shown with a another waveguide also with the antenna of the Radar sensor 10 in contact.
  • the passages 6, 7 of the Hollow shaft 5 can be suitable for the radar sensor transparent plugs can be closed, for example with plastic plugs.
  • a machine of the type shown can with the help of a corresponding electronic not shown Control unit taking into account the signal of the Radar sensor 10 significantly more needs-based and flexible be controlled than has been the case up to now under among others the above mentioned controls and Monitoring is incorporated into the machine control system can.
  • Control unit taking into account the signal of the Radar sensor 10 significantly more needs-based and flexible be controlled than has been the case up to now under among others the above mentioned controls and Monitoring is incorporated into the machine control system can.
