Definitions

  • the invention relates to a method for controlling a washing program in a washing machine, in particular a household washing machine, with a measuring device for determination the detergent concentration of the detergent or Rinse liquor, the washing program at least the program sections washing and Rinsing involves.
  • Washing machines with measuring devices of the detergent concentration in the tub located washing / rinsing liquor are well known.
  • the detergent concentration in the wash liquor in the program section Wash determined by measuring the surface tension and depending on the Detergent addition controlled by an automatic detergent dosing device.
  • the DE 195 29 787 A1 also proposes rinsing in the program section Determine the detergent concentration by determining the surface tension of the washing liquor and depending on this determine the duration of this program section.
  • a bottle washing machine is known from DE 89 09 081 U1, in which in the program section Washing a foam sensor controls the foam development and the automatic Control of the addition of an anti-foaming agent.
  • the detergent concentration values recorded in the Washing program section are only used for automatic dosing of detergent or other substances. Automatic dosing devices generally restrict the user in such a way that only certain types of detergent (liquid detergent, tablets) can be used. In the case of household washing machines, only metering devices for liquid detergents have been used so far, since powdered and tablet-form detergents clump or cake because of their hygroscopic properties and thereby endanger the trouble-free operation of the washing machine. In addition, they are also prone to failure due to the large number of mechanical components and make the washing machine considerably more expensive. These are the reasons why such dosing devices have so far only been used in commercial washing machines.
  • the invention thus presents the problem with a method for controlling a washing program of the type mentioned in a simple, inexpensive and particularly effective Way the entire process depending on the measured detergent concentration values to influence and thereby a satisfactory washing and To ensure washing results.
  • the measuring device for determining the detergent concentration determined values with underdosing to shorten the rinsing time, to reduce the number of rinse cycles and / or to reduce the amount of rinse water.
  • Overdosing increases the rinsing time, increases the number of rinses and / or Rinse water volume increased.
  • the underdosing is used for a washing program a predetermined target detergent concentration value predetermined duration of the program section Washing increases. This ensures a good washing result. additionally it may be advantageous to set the temperature of the wash liquor above that set by the user Increase the washing temperature, which also improves the washing result contributes. The time spent in extending the washing program section can can be saved by shortening the number of wash cycles; this ensures a constant duration of the entire washing program.
  • the overdosing is used for a washing program with a predetermined target detergent concentration value predetermined duration of Program section washing reduced. This can be done easily by reducing the Temperature of the washing liquor compared to the washing temperature set by the user or by reducing the number of post-heating steps after reaching the from User set washing temperature can be realized. Due to the increased detergent concentration a good washing result is nevertheless achieved. The time saved can be used to extend the rinse cycle; this also makes a constant Guaranteed the duration of the entire washing program.
  • the washing machine shown has a tub (1) in which a Drum (2) is rotatably mounted to hold laundry.
  • the tub (1) is on Springs (3) swingably suspended in the housing (4) and is used to dampen them Vibrations in the lower area due to shock absorbers (5) in relation to the housing base (4a) supported.
  • the drum (2) is reversed by a motor (6) added.
  • a microprocessor control (11) is used to control the different washing programs. provided that via signal lines (12) with various measuring devices and controls connected is. It issues time and status-dependent commands via control lines to various actuators, in particular to the motor (6), valves not shown for introduction of water in the detergent dispenser drawer (8) and to one described below Air volume flow source in the form of an air pump (14) with changeable pump power.
  • the device for determining the concentration of the detergent in the washing liquid.
  • This device measures the surface tension of the washing liquid using the bubble pressure method. For this purpose, put it in the tub (1) or in one with the washing liquid filled measuring cell via a capillary (15) an air flow is initiated by the air pump (14) is generated. This air flow causes the formation of Bubbles.
  • the pump power can be varied in this way by the microprocessor control (11) be that the bubble formation frequency is over a bandwidth of 1 Hz to 20 Hz changes.
  • the microprocessor control (11) With a pressure sensor (16), the first derivative of the resultant is continuously generated Pressure during the bubble break into an electrical signal and converted by the control computer the microprocessor control (11) converted into surface tension values.
  • the microprocessor control (11) for the frequency range of 1 Hz up to 10 Hz at intervals of 1 Hz surface tension values can either be controlled by Bubble frequency to the desired values or by an approximation method in which an approximation curve is measured by measured surface tension values any associated bubble formation frequencies is placed.
  • the determination of Detergent concentration is carried out according to a method described in the German patent application 100 29 505.3 is described.
  • the user dispenses detergent and any additives into the detergent drawer and starts the desired washing program. hereby the drum is set into reversing rotary movements by the motor and that Detergent is flushed into the tub with the introduction of water. After a wet phase follows the determination of the detergent concentration. For this, according to the above-described method, the surface tension bubble formation frequency characteristic added. The detergent concentration is determined from this characteristic and one of the assigned to five previously described dosage levels. Then the washing program with following parameters dependent on the determined dosage level:
  • a rinse cycle is dispensed with in the Rinse program section. This saves both water and the duration of the program. Instead of Dispensing with a rinse cycle can shorten all rinse cycles and use less rinse water be performed. The time saved can be put on the washing program section be opened to ensure a good washing result. An increase in Washing liquor temperature is also conceivable, but due to the sensitivity of some textiles rather than critical.
  • the rinse program section also switches to a rinse cycle waived, the amount of rinsing water then slightly in the remaining rinsing cycles is increased.
  • the flushing water quantities are set by the microprocessor control so that the total amount is less than with a program with the correct dosage. Instead of By not using a rinse cycle, all rinse cycles can be shortened and with less rinse water be performed.
  • the amount of rinse water is increased in the individual rinse cycles, to ensure a good wash result.
  • the rinsing time can be increased be to the complete sequence of the exchange processes described in DE 198 54 130 C1 to ensure. It would be conceivable to carry out an additional rinse cycle but does not seem practical because the washing machine user tends to have shorter program times wishes.
  • a shortening of the washing program section can also be achieved by reducing the number the post-heating steps after reaching the wash liquor temperature set by the user for the first time be achieved; this also saves heating energy. at extremely high overdosage may also result in a dilution of the wash liquor Fresh water supply possible, in which case at least part of the wash liquor must be drained beforehand is.
