Definitions

  • the invention relates to a water supply control for a washing machine with a washing drum rotatably driven in a tub and a circulating system for spraying the required for the wet washing, fed in individual feed cycles water in the laundry located in the washing drum.
  • the number of water supply cycles and the total amount of water supplied is matched to the maximum possible load of the washing machine, so that at a low load the moisture required for the dampening process already after a set number of water supply cycles, for example, after only two cycles , is reached and the subsequent cycles are superfluous.
  • the water supply phase is unnecessarily extended and the heating process can begin later.
  • the washing program in question is thus carried out in a period of time which is not necessarily long, involving a higher mechanical load on the washing machine during the spin-up and flooding and an increased energy consumption.
  • the invention is therefore based on the object to make the water intake phase for the wet washing in a washing machine so that the mechanical load on the washing machine and the energy consumption and the duration of the wash program are kept low overall.
  • the mass of the laundry introduced into the washing drum is first determined with the start of the washing program, and a certain amount of water is supplied in a first water supply cycle on the basis of the loading quantity.
  • a certain amount of water is supplied in a first water supply cycle on the basis of the loading quantity.
  • temporally adjusted reversing phase .DELTA.t1 of the washing drum water is absorbed by the laundry during resorting and completely distributed in a subsequent drum acceleration phase .DELTA.t2 by flooding in the laundry and expelled again at a high drum acceleration.
  • the expelled amount of water is determined and compared with a predetermined by the loading amount of water to either stop the water supply and start the heating process or to connect additional water supply cycles II to n until reaching the predetermined amount of water.
  • the loading amount is determined in an inertia method by a performance evaluation of the loaded washing drum during an acceleration phase and a plateau phase.
  • a basic amount of water is first supplied in this process and distributed before the acceleration phase by flooding in the laundry.
  • the washing machine shown comprises a tub 1 with a rotatably mounted in this, to a drive device (not shown) coupled washing drum 2.
  • the connected to a spray head 7 free end of the Umflut réelle 5 opens into the on a spring and damping system (not shown) movably suspended, formed from the tub 1 and the laundry drum 2 washing unit.
  • the fresh water required for the wet washing is introduced via the dispenser box 8 of the washing machine together with the detergent located in the dispenser in the washing unit with the inserted into the washing drum 2 9 laundry.
  • a heater 10 for heating the liquor for the washing process and a pressure sensor 11 for determining the water level in the tub 1 are arranged.
  • Fig. 2 shows an exemplary sequence of the fresh water supply to the washing unit, which includes a base water inlet cycle with 4kg in the washing drum laundry and then three consecutive water supply cycles I, II and III. In the drawing, the time course of the drum speed is shown in the respective water supply cycle.
  • the washing unit in a base water supply cycle a predetermined amount of water, in the present embodiment, two liters, fed and sprayed via the Umfluttechnisch 5 and the spray head 7 in the redistributed during a Reversier servess the washing drum 2 9 laundry.
  • the washing drum is first raised slowly and then accelerated to a speed of about 600 U / min.
  • a performance evaluation of the drum drive is carried out with the aid of the control and evaluation unit assigned to the washing machine, from which the loading of the washing drum is determined.
  • the water supply cycle I following the base water feed cycle comprising the charge detection comprises a period ⁇ t1 (variable reversing period) in which the washing drum 2 is operated in reversing rhythm.
  • a quantity of water determined on the basis of the loading quantity is supplied, lye standing above the lower edge of the washing drum 2 in the tub 1 is absorbed by the laundry 9.
  • the laundry is reorganized and rearranged to create the conditions for a uniform distribution of alkali and detergent in the laundry.
  • the duration of the reversing phase is variable and is set by the control unit of the washing machine on the basis of the determined in the base water supply cycle load.
  • a large load requires a long reversing phase .DELTA.t1, while the laundry with a small load and space in the washing drum in a shorter period .DELTA.t1 can be rearranged to ensure a uniform distribution of the liquor in the laundry.
  • the period ⁇ t2 (drum acceleration phase) following the period ⁇ t1 first comprises a flooding phase in conjunction with a gradual increase in drum speed in which the liquor present in the tub 1 is sprayed into the laundry 9 by means of the circulating system, and a drum high acceleration phase of, for example, 60 U / min / s, in which water is expelled according to the moisture level of the laundry and immediately sprayed back into the laundry with the help of the circulating system.
  • the liquid level in the tub 1 is determined by means of the pressure sensor 11 and determined by means of the control and evaluation of the washing machine, whether the expelled amount of water already corresponds to the optimal amount of water required for the respective washing process and the determined load.
  • the drum high-acceleration phase can be stopped and the water supply already in the first water supply cycle I stopped. That is, with a low loading amount, after just a short time, here about 200 seconds, the heating can be switched on and the washing process can be carried out.
  • the water inlet cycle I corresponding water inlet cycle II connects, in the beginning of the reversing phase .DELTA.t1 first a certain Amount of water is refueled. As long as in the current water supply cycle at the end of the drum acceleration phase .DELTA.t2 the optimal amount of water based on the measured load amount has not yet been reached, further water supply cycles III to n are performed.
  • a number of water supply cycles tuned to the load of the laundry drum determined in the basic water supply cycle are performed. That is, the smaller the calculated amount of charge, the lower the number of water supply cycles and the time required for the water supply. For example, for a load of six kilograms, four to five water supply cycles are required, whereas for example, for a load of two kilograms, only two to three water supply cycles are required to provide the optimum amount of water.
  • the duration of the variable reversing phase ⁇ t1 also decreases, so that the period for the water supply can be further reduced overall. While in the reversing phase ⁇ t1 at a higher loading amount (for example, 6 kg) for the uniform moistening of the laundry, 60 to 90 seconds are required, with the loading amount of 2 kg already 15 to 30 seconds are sufficient.
