Definitions

  • the invention relates to a method for operating a washing machine with a pressure sensor and a washing machine suitable for this purpose.
  • the invention particularly relates to a washing machine with a tub, a drum for receiving laundry, a drive motor for the drum, a pressure sensor for determining a hydrostatic pressure p as a measure of a height of an aqueous liquid in the tub, a control device and at least one position sensor for Determining a position and a behavior of a vibration system of the washing machine, which comprises the tub, the drum and the drive motor during operation of the washing machine, and a suitable for performing this method washing machine.
  • the lowest possible water requirement is important. Using less water also consumes less electrical energy to heat the water needed for a washing process.
  • the amount of water used must be sufficiently large so that laundry to be washed can be sufficiently wetted and washed. It is therefore important to know the water requirement for a laundry items to be washed as accurately as possible and also to ensure a sufficient amount of free liquor for washing.
  • the wetting phase should preferably be optimized so that each batch of laundry with a coordinated amount of water in the tub or in the drum (hereinafter referred to as “laundry drum “referred to) before the actual washing process in the shortest possible time completely and evenly wetted.
  • the amounts of water used for the wetting should also be reproducible, so that in particular a reproducible entry of heat energy is ensured in the water.
  • a wetting phase (also referred to as "net phase”) is thus to provide an optimal amount of water for the washing process and information about the load. Therefore, the wetting phase is very important for every washing program important.
  • the pressure values during the reversing of the drum and / or at standstill are often used for the interpretation.
  • the realization of the wetting is known in that after the entry of a certain amount of water in a drum containing a washing and a fürfeuchtungsphase a rotating drum is stopped. Water then drips from the laundry until an approximately stable state is reached, which can be demonstrated by a nearly constant or only slightly changing pressure value for the hydrostatic pressure of the water. Depending on the extent of the pressure increase at standstill of the drum is then decided whether the laundry items are saturated with water.
  • an electromagnetic water level controller for controlling the level of the aqueous liquid used in a washing machine (generally clean water or a wash liquor containing a surfactant to be used for cleaning) during the wetting phase and the washing phase
  • a pressure sensor for measuring a hydrostatic pressure (hereinafter abbreviated to "pressure") controls the water supply.
  • improper operating conditions are known in a washing machine, which can lead to damage or at least to a reduced life of a washing machine.
  • a heater for heating wash liquor should be put into operation only if immersion of the heater in the wash liquor is ensured. Otherwise, it could lead to overheating and thus damage to the heater.
  • Another example is the avoidance of spin or spin start on a drum still immersed in wash liquor or water. This could cause damage to the drive motor for the drum or at least reduce its life.
  • the level is often determined in a washing machine by means of a relatively high-resolution analog pressure sensor.
  • the pressure sensor detects the resulting pressure of a sealed, air-filled tube immersed in the water level Pressure chamber, wherein the pressure is dependent on the filling level in the tub of the washing machine.
  • the fill level determined with this measurement system may be inaccurate by design. For example, filling conditions due to the rotation of the drum of a washing machine can be detected as too low, when air has penetrated into the pressure chamber. Too high levels can be due to a faulty calibration of the pressure sensor, for example if the calibration was done on a non-ventilated pressure system.
  • the values of the hydrostatic pressure measured by a pressure sensor depend on the respective washing machine as well as on their installation conditions. For example, a possible skew of the washing machine, i. an inclination of the washing machine from the horizontal, affecting the measurement of hydrostatic pressure.
