Definitions
- the invention relates to a method for washing laundry in a process-controlled household ash machine, which has an alkali container for taking up laundry and lye intended for washing the laundry, in or on which a heating device and a temperature sensor are attached, wherein during a filling phase, water is poured into the tub for washing and the temperature sensor sends signals for the respective temperature of the water or the lye to the process control during the washing process and the latter derives commands for the control of the heating device for heating the lye from the temperature signals, and the Washing process with a heating phase, which begins when the heating device is switched on, and a post-washing phase with a largely constant temperature and a defined constant time from the start of the switching on of the heating device to the end of the post-washing phase.
- washing machines of the type mentioned have been manufactured for years by the owner of this patent and form a notorious state of the art.
- the background to the definition of the duration of the washing process, determined by the start of the heating phase and the end of the post-washing phase, is to ensure consistently good washing results by the time factor of the so-called Sinner circle, which is always constant for the factors temperature, time, mechanics and chemistry Commits the sum for which the pure washing process remains constant.
- the temperature of the inlet water is no longer in the previously expected range under extreme conditions, which assumes an inlet temperature of about 12 ° C. Fluctuations of + 3 ° are of little importance in this context. However, the expected inlet temperature deviates even further downwards under extreme conditions, so that inlet temperatures of e.g. B., 5 ° C are possible. Then, however, the heating-up phase is extended so significantly that the subsequent post-washing phase is neglected due to the washing process being of the same overall length. Then the mechanical factor has the same proportion, but the temperature factor decreases because the temperature is too low over 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 it constantly large under otherwise identical conditions.
- Washing machine washed in different program steps with a washing liquor of changing temperature.
- the laundry is placed in a washing drum rotatably mounted in a tub and the washing liquor (water mixed with cleaning agent) is fed to the tub or the washing drum.
- Different temperatures can be set in the washing program, which usually range from tap water temperature (DkaltD) to 95 ° C for hot laundry.
- the washing machine has a heating device for heating the supplied water or the washing liquor to the set temperature.
- mechanical temperature sensors such as liquid expansion sensors or bimetal sensors or electronic temperature sensors such as thermistors (NTC resistors) are arranged in the wash tank.
- Washing process provides, as usual, to regulate the temperature of the washing liquor to a predetermined control interval between a maximum and a minimum value, during the regulating process to continuously determine the sum of the thermal energy supplied to the washing liquor since the beginning of this regulating process, and to supply thermal energy interrupt if the sum of the thermal energy supplied exceeds a predetermined process energy value.
- these measures no longer take into account the constant duration of washing processes regulated in this way, so that on the one hand the time factor can fluctuate and the rules of the Sinner circle are no longer taken into account. This has the effect of a cleaning effect that is no longer consistently good.
- the customer can no longer count on an overall process duration of the same length for certain washing programs.
- the invention has for its object in one described above
- Water or the alkali is determined at or after the end of the filling of water, that at a determined temperature of less than a standard value for the amount of water freshly run into the tub, the heating device is switched on before the start of the washing process and that the start of the washing process is postponed for a defined period of time.
- the measurement of the duration of the cleaning cycle is independent of the starting temperature. This enables both the temperature factor, i.e. H. adapt the amount of thermal energy introduced, as well as the time factor, to 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 takes place during the filling of water or alkali and before or when the heating device is switched on, the greatest accuracy of the duration of the washing process can be expected.
- the standard value is best located in the range from 10 ° C. to 15 ° C., because the inlet temperature will regularly be in this range. Under extreme conditions, the inlet temperature can deviate sharply downwards, namely, for example, when the washing machine is installed in a room that is subject to large temperature fluctuations.
- the pipe system in the cold or warm, free-standing room will be flowed through by water of a constant temperature (e.g. at 12 ° C) in the later course of the filling process.
- the amount of water that has run into the tub will have a mixing temperature that deviates significantly from the standard value (e.g. 12 ° C).
- the time period can be defined by reaching the standard value. If the inlet temperature is below the standard value, the start of the washing process can be set precisely by starting the heating phase by switching on the heating device and waiting until the temperature of the washing liquor has reached the standard value (e.g. 12 ° C).
- a predefined length is set for the period of the shift in the start 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 widely, and a standard deviation will therefore be specified, which is always required if the determined inlet temperature deviates from the standard value by a predetermined value. The value of this deviation can be 3 °, for example. If this deviation is reached or exceeded, a fixed predetermined period of time for the postponement of the start of the washing process is inserted. If the total input of thermal energy and time was then too large, the cleaning knitting is at least not worse than desired. On the other hand, a loss in these factors due to a shift that is too short, if the actual inlet temperature is still lower than the predetermined time for the shift, would be very small, and the resulting reduction in cleaning efficiency would probably no longer be measurable.
- FIG. 2 shows a temperature profile in comparison to that according to FIG. 1 after a
- the washing 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.
- S a standard value assumed for this example
- the filling phase F is completed at time t.
- a water level sensor which is not described further, can now, for example, cause a switch in the circuit of the heating device to be closed.
- the washing liquor continuously heats up (the inflow of water had taken detergent from a detergent dispenser, for example) until the target value for the set washing temperature (eg 60 ° C) has been reached.
- the heating device is switched off again, and the washing liquor cools to a value below the target temperature, for example, until the end of the washing process W, which is essentially characterized by the introduction of mechanics due to intermittent drum rotations. B. 50 ° C, from.
- the end of the washing process W is determined by a fixed period of time t -t
- FIG. 2 The start of a washing program is shown in FIG. 2.
- the diagram line from FIG. 1 is also drawn in thin lines here.
- the heating also begins after the filling phase F has ended.
- the beginning of the heating does not coincide with the start of the washing phase W.
- a delay phase D is switched on here, which - as in the example shown - can either last until the temperature of the warming washing liquor has reached the standard value S or has a predetermined duration which is approximately similar is long, like the duration shown in the example.
- the delay phase D begins again
