Definitions

  • the invention relates to a program-controlled washing machine according to the preamble of claim 1.
  • Washing machines of this type are generally known.
  • the washware in order to reduce the wash liquor still contained in the washware after each wash cycle and thus to increase the efficiency of this wash cycle, the washware is spun at the end of each wash cycle.
  • the laundry drum containing the laundry is operated during the spin cycle at a high rotational speed, which is approximately in the order of magnitude of 800 to 1200 rpm.
  • the mixture of water and detergent that is expelled from the laundry or spun material and passes through the perforated drum jacket often creates foam in the tub after a spin cycle of a few seconds, which can lead to an interruption the work of the drain pump.
  • the invention has for its object to improve a program-controlled washing machine of the type mentioned in such a way that at the earliest possible time after completion of the washing process with the maximum possible drum speed, the laundry without the risk of foaming in the suds container which hinders the further pumping out of the washing liquor can be thrown.
  • the laundry drum of a washing machine is referred to, which is rotatably housed in a tub 2 (washing tub).
  • the laundry drum 1 is provided in the usual manner on its entire outer surface with perforations for the passage of water or washing and rinsing liquor and is motorized can be driven either in the wash cycle or in the spin cycle.
  • This laundry drum can therefore also perform the spin cycle of the laundry, which usually ends a washing program or rinsing program.
  • the perforated laundry drum 1 containing the laundry is partially immersed in the wash liquor (wash liquor, rinsing water) present in the tub.
  • the drive motor 5 and thus the drive 6 for the laundry drum 1 are controlled via an electrical regulating and control unit 7.
  • a measuring pipeline 8 goes from the drain line 3, which is based on the water pressure in the Contains drum or the detergent appealing measuring device 9 for the liquor level in the tub 2 contains.
  • An analog or pneumatic pressure sensor advantageously serves as the measuring device 9. It would also be conceivable to use a pressure-independent device as the measuring device for detecting the foam limit.
  • the regulating and control unit 7 is preceded by a level comparator 10 and a control element 11 influencing the current for the drive motor is connected downstream.
  • the Nieveau comparator 10 receives its data from the analog pressure sensor 9 (measuring device), the output signals (level signals) of which are an indication of the foam formation or the foam development during the spinning process. These output signals represent a controlled variable for the drive motor 5 of the laundry drum 1 and thus for the regulation or influencing of the spin speed.
  • the aim is to ensure that the laundry can be dewatered as soon as possible at the earliest possible time after completion of the washing process with the maximum possible laundry drum speed, irrespective of the particular type and amount of laundry as well as the type and amount of detergent is without swirling existing wash liquor from the last wash cycle. This prevents excessive foam from forming in the laundry drum. It follows the advantageous possibility that now a complete pumping of the residual liquor can be carried out and a good rinsing effect can be achieved with reduced water consumption.
  • the initially low initial spin speed for the washing drum after the gentle start is increased in small steps, e.g. B. 50 rpm only increased if no increase in the drum water pressure is measured or registered via the analog pressure sensor 9 connected in parallel with the liquor or lye level, and consequently also no further increase or increase in the Foaming is present, which means that an existing certain low foam limit in the laundry drum for a certain period of z. B. is equal to or falls below a second.
  • a certain critical foam limit is not exceeded at a drum speed of around 100 rpm or when the centrifugal setpoint is activated, the spinning process is stopped immediately and a rinsing process is repeated or interposed.
  • the analog pressure sensor 9 used in the washing machine described makes it possible to detect all washing levels, ie any level between 35 mm water column (foam level limit) and 300 mm water column (safety level limit) can be controlled.
  • the spin cycle is also interrupted and the amount of rinsing water in the subsequent rinse cycle is increased if the foam limit is no longer undershot at a predetermined or specified washing drum speed. Furthermore, the spin cycle is interrupted and the duration of the rinse cycle of the subsequent rinse cycle is extended and / or the reversing process (movement mechanism for shifting the items to be washed) is increased during the subsequent rinse cycle if the foam limits are no longer undershot at a predetermined wash drum speed.
  • a further process step is that the washing drum speed is reduced until the washing drum comes to a standstill when the foam is present and then accelerated again to at least 100 rpm for a predetermined or specified period of time.
  • This washing drum speed reduction u. Acceleration is expediently repeated several times, although the number of these repetitions is limited depending on the type of laundry or washing program selection.
  • the predetermined laundry drum speed reduction steps and / or laundry drum speed acceleration steps can, depending on the type of laundry, program selection and / or number of spin cycle value additions, be appropriately multiplied by a corresponding factor.
  • the laundry drum speed reduction and / or acceleration can be increased degressively or progressively.
  • the program-specific spin duration in the individual processes shown is only started when a predetermined or specified washing drum minimum speed and / or minimum startup period has been exceeded.
