Definitions

  • the invention relates to a method for controlling the generation of foam, in particular in a treatment of laundry with foam, in a program-controlled washing machine and a particularly suitable for performing this method washing machine.
  • the laundry to be washed is treated only with an amount of water or wash liquor, also referred to as a "liquor", which is sufficient for the laundry to be washed to be saturated with water and a minimum free liquor, generally 2 to 3 liters, a mass transfer between the heater for heating the wash liquor and the laundry allows.
  • the free liquor corresponds to the remainder of the wash liquor which is not bound by the wash and thus exists as a liquid.
  • the appropriate dimensioning of the water quantity or liquor is ensured by suitable methods for regulating the water level in the drum and the adjustment of the amount of water to the suction capacity of the laundry.
  • the free liquor results after deduction of the amount of water bound in the laundry of the amount of water filled in the washing machine.
  • Cotton fabric binds about 200% of its own weight, so that a load of 6 kg of cotton fabric binds about 12 liters of water.
  • the energy consumption of a washing machine is essentially determined by the energy required for the heating of the water. A reduction in the amount of water in the washing machine would therefore be desirable, in particular a reduction in the amount of free liquor. However, the free fleet must ensure the heat transfer from the heater to the laundry. A reduction of the fleet and thus a reduction in energy consumption are thus difficult to achieve.
  • An alternative to this known washing process is the washing with foam, which can be produced by introducing mechanical energy into a wax liquor.
  • the foam takes care of the heating and cleaning of laundry to be cleaned.
  • Foam which occurs undesirably in a washing machine is destroyed by switching on a heating device.
  • the drum In order to destroy the foam in the wider vicinity of the heater, the drum is rotated slowly, so that more foam passes to the heater and is destroyed there by supplying heat.
  • the DE 102 34 472 A1 discloses a method for removing foam in a tub of an electronically controlled drum washing machine as a result of a program step, which is provided for dewatering the tub, with a Laugenablaufsystem arranged at the bottom of the tub with a drain pump and with a sensor for determining the height of the tub located in the tub Liquid.
  • the course of the sensor signal (P) is recorded during the operation of the drain pump, contains a gradient Ap n / .DELTA.t n compared to Ap n-1 / .DELTA.t n-1, indicating the presence of foam, whereupon one of the Gradient-matched foam treatment measure is initiated.
  • the EP 0 268 155 A2 describes a washing machine with a device for preventing foaming.
  • Foam brake is proposed, wherein the speed of a laundry drum drive motor is reduced until the foam limit has been adjusted back to a certain low level, which is then consistently below.
  • the object of the invention is to provide a method for controlling the generation of foam, in particular in a treatment of laundry with foam, in a program-controlled washing machine and a particularly suitable for performing this method washing machine.
  • the heating device heats the foam and / or the wash liquor.
  • the detection of foam can thus be carried out, for example, via a conductance measurement with two electrodes in the lower region of the tub.
  • a sensor used in any case in a known washing machine referred to as a water level regulator, may, for example, be used as the sensor.
  • a sensor used in any case in a known washing machine referred to as a water level regulator, may, for example, be used as the sensor.
  • the hydrostatic pressure is advantageous that a significant increase in pressure can be measured if, during rotation of the drum, in particular during spinning, a gap between the drum and the tub is completely filled with foam.
  • n and n may be the same or different.
  • speed differences ⁇ U n and ⁇ U m may be the same or different.
  • step a5) or b5) water is introduced in an amount which allows a normal washing process with a wash liquor without foam and this washing process is carried out.
  • the display of too low (b6) or too high or incorrect detergent dosing (a7) is preferably carried out acoustically and / or optically.
  • a signal can be output to a control device of the washing machine, which initiates further steps. Is it e.g. despite a maximum rotational speed of the drum (also referred to as "maximum spin rate") not possible to generate sufficient foam, the washing process can be continued after the addition of water to the usual level as a conventional washing process. For the user of the washing machine, an audible or visual signal may be issued about the lack of or insufficient detergent addition.
  • the washing process can also be continued as a conventional washing process after addition of water to the usual level.
  • an acoustic or visual signal can be output to the user of the washing machine on the wrong or too high detergent addition.
  • step a4) and / or a6) After carrying out step a4) and / or a6) for a predetermined period of time, the inventive method can be carried out again.
  • a strong turning of the drum can be switched off and switched over to a normal reversing operation of the drum for a predetermined time.
  • the absorption of the water in the foam state is supported by the laundry items and thus effectively reduces the amount of foam.
  • a drain pump can also be switched on to the amount in the tub and available for generating foam to reduce to washing liquor. Following this lathering of the foam, an attempt can be made to switch back to spinning and, if a desired foam concentration is set, to carry out a foam-based washing process.
  • the drum rotates, preferably at a speed U in the range of 200 to 600, preferably 230 to 500 revolutions per minute.
  • the lower limit is generally given by the resonance speed of the vibration system and the upper limit by the maximum possible spin number.
  • U to an evaluation of a target / actual difference in rotational speed - U is at a rotation of the drum for detecting (a) can be used of the foam.
  • the foam can brake a rotating drum, whereby there is a difference between the target and the actual speed .
  • the association between a specific foam concentration and the target / actual difference is generally stored in a data memory of the drum washing machine.
  • a desired concentration c v of the foam which is predetermined in the range of c 1 to c 2 , can be adjusted and / or maintained by a continuous change in the rotational speed U of the drum.
  • the concentration c 1 corresponds to the hydrostatic pressure p 1 and the concentration c 2 to the hydrostatic pressure p 2 .
  • the invention also relates to a washing machine with a program control for controlling the program flow, a rotatably mounted in a tub drum, one at the bottom of the tub arranged Laugenablaufsystem with a drain pump, a drive motor for the drum, a heater, a sensor for determining a quantity of in the tub liquid or a foam, and switching means for rotating and stopping the drum, wherein the switching means and the sensor can perform the inventive method described herein.
  • the foaming control method of the present invention When the foaming control method of the present invention has achieved the setting and maintenance of a desired concentration of foam, the treatment of a laundry load with foam can be carried out.
  • the invention enables the stable operation of a washing machine in a foam using washing process. A desirable foaming is promoted while preventing foaming.
  • the invention also ensures sufficient cooling of the heating device of a washing machine and can prevent the switching on of the heater when there is insufficient foaming.
  • FIG. 1 An embodiment of a washing machine according to the invention for carrying out the method of the invention shows FIG. 1 , Other embodiments are conceivable. The embodiment will be explained below.
  • FIG. 1 is a schematic representation of the relevant parts of a washing machine in which the described method can be performed.
