Definitions

  • the invention relates to a method for washing laundry in a process-controlled domestic washing machine, which has a tub for receiving laundry and for washing the laundry of certain liquor in or on which a heater and a temperature sensor are mounted, wherein during a Einfeldllphase Is filled with water for washing in the tub and the temperature sensor during the washing process signals for the respective temperature of the water or the liquor to the process control and this derived from the temperature signals commands for controlling the heater for heating the liquor and the temperature of the water or the liquor is determined at or after the end of the filling of water and wherein a washing process, which comprises a heating phase and a Nachwaschphase without further introduction of heating energy for a fixed, stored in the washing program period to the end of the Nachwaschphase runs.
  • washing machines of the type mentioned are manufactured for years with the owner of this patent and form a notorious state of the art.
  • the background of the definition of the duration of the washing process, determined by the beginning of the heating phase and the completion of the post-wash phase, is to ensure consistently good washing results by the fact that the time factor of the so-called Sinner circle, which is always the same for the factors temperature, time, mechanics and chemistry Sum commits, remains constant for the pure washing process.
  • the temperature of the feed water under extreme conditions is no longer in the expected range, which assumes a feed temperature of about 12 ° C. Fluctuations of ⁇ 3 ° are of little importance in this context.
  • the expected inlet temperature differs under extreme conditions especially from time to time downwards, so that inlet temperatures of, for. B., 5 ° C are possible.
  • the heating-up phase is extended so significantly that the subsequent post-washing phase is too short because of the overall washing process of the same length. Then the mechanics factor has the same share, but the temperature factor decreases because the temperature is too low for a large proportion of the washing process (in the heating phase).
  • EP 0 859 304 B1 proposed to monitor the entry of thermal energy and to keep always the same size under otherwise identical conditions.
  • the laundry is washed in a washing machine in various program steps with a wash liquor changing temperature for washing laundry in the home.
  • the laundry is introduced into a laundry drum rotatably mounted in a tub and the wash liquor (water mixed with cleaning agent) is supplied to the tub or the laundry drum.
  • different temperatures can be set, which usually range from tap water temperature (cold) up to 95 ° C for cooking laundry.
  • the washing machine on a heater.
  • mechanical temperature sensors such as liquid expansion sensors or bimetallic sensors or electronic temperature sensors such as thermistors (NTC resistors) are arranged in the wash tank.
  • the known method for adjusting the temperature of the wash liquor in the washing process provides, as usual, to regulate the temperature of the wash liquor to a predetermined control interval between a maximum and a minimum value, during the control process, the sum of the thermal energy supplied since the beginning of this control process of the wash liquor continuously to determine and to interrupt the supply of thermal energy when the sum of the supplied thermal energy exceeds a predetermined process energy value.
  • these measures no longer take account of the constant duration of such controlled washing processes, so that on the one hand the factor time can fluctuate and the rules of the Sinner circle are no longer taken into account. This has an effect in terms of no longer consistently good cleaning effect. On the other hand, the customer can no longer expect the same total process time for certain washing programs.
  • a laundry washing procedure is also off GB 957 944 A known.
  • water is admitted at the beginning of a washing program for washing at a mean temperature within a fixed period of time until a predetermined level is reached.
  • the heating is switched on until the end of the fixed period, irrespective of the temperature of the water that has run up to it.
  • the temperature of the water is determined with a temperature sensor and optionally further heated to a predetermined average temperature, in which the heating remains switched on until the temperature is reached. After reaching the temperature will be carried out a Nachwaschphase fixed predetermined duration.
  • the method for washing clothes is filled with the water and heated in the same way to the middle temperature, wherein on reaching the average temperature, a further washing process for a fixed period of time until the end of a Nachwaschphase and wherein the washing process, a heating phase during the the water is heated from the middle to a high temperature, and includes the post-wash phase.
  • the invention is based on the object in a method described above and then to ensure the guaranteed compliance with the influences of the factors involved temperature and time when the temperature of the accumulated water deviates from the intended default value.
  • the design of the period for the cleaning cycle of the initial temperature is independent. This makes it possible to both the temperature factor, d. H. the applied amount of thermal energy, as well as the time factor to adjust the requirements given by the Sinner circle. This also means compliance with the desired duration of washing processes under typical household conditions.
  • the first determination of the temperature during the filling of water or alkali and before or when switching on the heater can be expected with the greatest accuracy of the duration of the washing process.
  • the inlet temperature will regularly be in this range. Under extreme conditions, the inlet temperature can deviate sharply downward, namely, for example, when the washing machine is placed in a room that is inferior to large temperature fluctuations.
  • the line system which is in the cold or warm, free space, will be followed by approximately constant temperature water (for example at 12 ° C.) later in the filling process.
  • the amount of water run into the tub will have a mixing temperature that is significantly different from the standard value (e.g., 12 ° C).
  • Deviations from above are rather harmless for compliance with the cleaning effect, even if the washing process is thereby carried out with an overall slightly higher input of thermal energy with a constant effective washing time. Deviations downwards will have no harmful effects due to the transfer of the start of the washing process because, despite the beginning of the liquor action on the laundry with a lower temperature and the associated prolongation of the heating phase, the duration of the effective washing process is maintained overall.
  • the standard value e.g. 12 ° C
  • a predefined length is set for the duration of the shift of the beginning of the washing process. It can be assumed that the deviations of the inlet temperatures from the standard value seldom assume extreme values or fluctuate greatly, and will therefore define a standard deviation, which is always set when the determined inlet temperature deviates downward by a predetermined value from the standard value. The value of this deviation may be, for example, 3 °. If this deviation is reached or exceeded, a fixed predetermined time period for the shift of the beginning of the washing process is inserted. If the total input of thermal energy and time was then too large, the cleaning effect will at least not be worse than desired. On the other hand, a loss in these factors by too short a shift, if the actual feed temperature should be even lower than the predetermined time period for the shift, would only be very small, and the resulting reduction in the cleaning effect would probably no longer be measurable.
  • Fig. 1 a temperature profile of the wash liquor over time after a water inlet with typical inlet temperature (default) and
  • Fig. 2 a temperature profile compared to that according to Fig. 1 after a water inlet with a feed temperature below the standard value.
  • the temperature response in washing program runs in a washing machine according to Fig. 1 .
  • the wash program begins with an inflow of unheated water, for example from a domestic water network.
  • the incoming water has a temperature according to a standard value S assumed for this example, namely 15 ° C. It is further assumed simplifying that the filling phase F at time t 0S is completed.
  • a not further described water level sensor can now cause, for example, the closing of a switch in the circuit of the heater. This begins the continuous heating of the wash liquor (the inflowing water had taken detergent, for example, from a dispenser) until the target value for the set wash temperature (eg 60 ° C) is reached.
  • the heater is switched off again, and the wash liquor cools to the end of the washing process W, which is characterized essentially by the introduction of mechanics due to intermittent drum rotations to a value below the target temperature, z. B. 50 ° C, from.
  • the end of the washing process W is determined by a fixed time t ES -t 0S , which is stored in the washing program, and initiates the re-supply of unheated water at time t ES , with a cool down phase (so-called cool down) and the rinsing phase R starts.
  • the washing process will continue according to the in the diagram of Fig. 1 operated course shown. That is, although now the initial temperature is somewhat lower than typically, the washing process W now begins with lower initial temperature, so that the heating phase t IS -t 0S takes longer time than at the start of 15 ° C, which is now the part of the washing process W is lost, in which the wash liquor cools to the end t ES again. This guarantees that the time factor is adhered to.
  • the period of time within the washing process W is shortened in comparison with the typical process shown.
  • Fig. 2 An example in which significantly cooler water (eg, only 6 ° C warm water) at the beginning of a wash program, is in Fig. 2 shown.
  • the diagram line is off Fig. 1 also shown here in thin lines.
  • the heating also begins after completion of the filling phase F.
  • the beginning of the heating does not coincide with the beginning of the washing phase W. Rather, here is a delay phase D is switched on, which - as in the example shown - either last until the temperature of the warming wash liquor has reached the default value S, or has a predetermined duration, which is approximately similar is long, like the duration shown in the example.
  • the washing process W then likewise begins again with a predetermined time duration t EK -t 0K , which is just as long as t ES -t 0S . This ensures that the time factor in each case of the inlet temperature in the washing process can not be neglected.
