Thereafter, for example, cold tap water can also be introduced, whereby preheating is not required is. It is thus advantageously possible to achieve an efficient washing performance in an energy-saving manner.

  • a use of an exemplary embodiment of the device 105 during a washing process in the washing machine is described below by way of example:
  • the water inlet 115 is switched by the valve 235.
  • the incoming water is passed on to the various waterways via the water switch 220 in order to control the various compartments of the dispenser drawer 110 or the door inspection glass flushing 252.

  • water is introduced from the water tank 205 via the storage tank line 225, the water from the water tank 205, which has been preheated to room temperature, is used for the washing process.
  • cold water runs through the water tank line 215 into the water tank 205, which then gradually heats up again to room temperature.
  • the air layer 242 divides the water tank 205 here by way of example into two halves, the inlet section 244 and the outlet section 246.
  • the washing machine is optionally designed for large loads in order to be able to handle a large amount of laundry if necessary. As a rule, however, the amount of laundry that occurs is significantly less, so that correspondingly less water is required for the washing process.
  • the two tank halves of the water tank 205 are thermally separated by the air layer 242.
  • the water tank 205 is formed by the partition walls 240 as an elongated channel designed. This largely prevents the incoming cold water from being mixed with the water preheated to room temperature in the water tank 205.
  • the inlet-side tank half of the water tank 205, the inlet section 244 is slightly larger than the outlet-side Tank half of the water tank 205, the output section 246.

  • the water tank 205 is optionally also designed to be larger, but this is limited by the installation space inside the washing machine.
  • a smaller design of the water tank 205 is also possible, in this case a smaller amount of water preheated in the water tank 205 is available in relation to the amount of laundry. It is therefore advantageous to design the water tank 205 in the manner mentioned, corresponding to a maximum load quantity of the washing machine with a margin of +/- 50 percent towards larger or smaller design volumes.
  • the washing machine is loaded with textiles made of cotton, approx. Twice the amount of water is absorbed in relation to the mass of the textiles. For example, 1 kilogram of cotton absorbs around 2 kilograms or 2 liters of water. This shows that the tank content of the water tank 205 is not sufficient to completely moisten the laundry when the receiving volume and the maximum load amount correspond, depending on an actual load amount in the wash cycle.
  • FIG. 3 shows a flowchart of a method 300 (subject matter not claimed by the claims) for operating a device for supplying water for the washing machine according to an exemplary embodiment.
