Definitions

  • the invention relates to a method for operating a washing machine and a washing machine.
  • the invention relates to a water supply control for a washing machine.
  • a washing machine with a tub for holding water, a rotatably mounted in the tub washing drum for receiving laundry, a loading opening for loading the washing drum with laundry, a door to close the loading opening and a door seal for Sealing of the door in the loading opening in the closed state is known, which has a water supply control for a wet-washing process, in which washing liquid containing water and detergent is completely bound in the laundry in the washing process.
  • a washing process called moist washing, with the moisture of the laundry lying below the saturation moisture level, the washing liquid present in the washing process is bound in the laundry. Due to a low, non-contacting the washing drum washing liquid level in the tub, the washing liquid introduced into the laundry to achieve a uniform wetting and distribution of the detergent is expelled by flooding centrifugal and sprayed through a flooding back into the laundry.
  • the invention thus raises the problem of providing a method for operating a washing machine and a washing machine, in which the detergent can be optimally introduced into the laundry when the water supply.
  • the achievable with the present invention consist in addition to an optimized introduction of detergent into the laundry during the water supply is that in the water supply control is not necessarily a Umflutungssystem needed. As a result, the washing machine is cheaper compared to a washing machine with Umflutungssystem.
  • the water is introduced directly into the washing drum and in the laundry, so that in the water possibly present detergent can be introduced into the laundry, without that after flushing from the sump in the form of free liquor to the Laundry, must be transported to exist as a bonded fleet.
  • the speed of the washing drum is determined such that the laundry rests as a ring on the washing drum and water introduced via the feed device remains inside the washing drum or substantially remains.
  • the water supplied into the washing drum can therefore be absorbed by the laundry immediately.
  • more than 95% of the water introduced remains inside the washing drum, more preferably 97% of the water introduced inside the washing drum.
  • that ... water introduced via the feeder remains inside the washing drum or substantially remains it is meant that the water does not or substantially does not pass through openings of the washing drum into the tub and thus into its sump.
  • a speed of the washing drum, in which the laundry rests as a ring on the washing drum, is also referred to as the application speed.
  • the application speed is a speed of the washing drum, in which the laundry present in the washing drum due to centrifugal forces to the jacket of the washing drum applies.
  • the application speed is the lowest speed of the washing drum at which the laundry is fixed i. without falling off of it rests against the drum shell. The laundry, when it reaches the highest point of its orbit when the drum rotates, remains attached to the drum shell due to the excess of gravity and adhesion (adhesion) that exceeds gravity. At a speed of the washing drum greater than or equal to the application speed is therefore omitted any case of washing in the drum.
  • the water introduced into the washing drum during the adjustment of the speed of the washing drum to the specific speed via the feed device preferably contains detergent.
  • the water is passed through a laundry detergent drawer of a Ein Albanykastens via the feeder into the washing drum.
  • the speed range at which this takes place can be, for example, 60 rpm, and depending on the load and the specific properties of the textile materials, it can also be 120 rpm or higher.
  • the height of the speed of the washing drum affects the thickness of the scrubber. It may be advantageous that the laundry ring has the smallest possible thickness so that the water with the detergent passes unhindered into the core of the laundry.
  • a disadvantage of a relatively high speed of the washing drum has the effect that the water introduced into the washing drum is pressed through the washing ring due to the centrifugal force and then leaves the washing drum via the openings.
  • the above-described optimum speed range is or is determined as a function of the load quantity.
  • the loading quantity can be determined in advance by a known load detection method.
  • the loading amount is determined in an inertia method by a performance evaluation of the loaded washing drum, which is necessary to accelerate the washing drum and the laundry therein.
  • the step of determining a rotational speed of the washing drum therefore comprises the step of determining a loading amount of laundry in the washing drum and determining the rotational speed as a function of the determined loading amount.
  • the speed of the washing drum which is adjusted while the water is introduced into the washing drum via the feeder, is higher, the higher the loading amount.
  • a relatively low speed of the washing drum during the water supply is advantageously controlled at a relatively low load, while at a relatively high load a relatively high speed of the washing drum is driven during the water supply.
  • a speed of the washing drum e.g. 120 rpm, while at a load of 8 kg, during the water supply, a speed of the washing drum of e.g. 600 rpm is controlled.
  • the step of determining the rotational speed as a function of the determined loading amount comprises selecting the rotational speed from a list in which each load quantity is assigned a rotational speed.
  • the list can be stored, for example, in the washing machine in the form of a table in which each load is assigned a speed.
  • the step of determining the rotational speed as a function of the determined loading amount comprises calculating the rotational speed using the determined loading amount.
  • the speed can be calculated using a formula.
  • a corresponding algorithm is stored in the washing machine, which describes a relationship between the load and the speed of the washing drum to be determined.
  • the method comprises the step of setting the speed of the washing drum to the determined speed over a first period of time and Reducing the speed of the washing drum after the first period expires.
  • the speed of the washing drum during the water supply from an initial certain speed, for example its optimum, is continuously lowered during the water supply. This is advantageous because the thickness of the laundry ring is reduced with increasing moisture during the water supply. If the speed of the washing drum is reduced during the water supply, the thickness of the scrubbing ring remains uniformly low enough so that the water can be introduced unhindered into the core of the above-described scrubbing ring.
  • the reduction in the speed of the washing drum during the water supply may be linear and / or following another mathematical function.
  • the speed of the washing drum is linearly reduced after the first period of time.
  • the speed of the washing drum is gradually and / or exponentially reduced after the first period of time expires.
  • the method for operating the washing machine preferably represents a water supply control for the wet-washing method.
  • the invention further relates to a washing machine with a tub for holding water, a rotatably mounted in the tub washing drum for receiving laundry, a loading opening for loading the washing drum with laundry, a door for closing the loading opening, a door seal for sealing the door in the Loading opening in the closed state, arranged in and / or on the door seal feeding device for introducing the water into the washing drum and a control or regulating device, which is designed to control a method according to one or more of the embodiments described above and / or to control ,
  • the feeder is preferably arranged and / or oriented such that it can introduce the water into a core of the laundry which is in the wash drum during the feeding of the water. As a result, little water gets into the sump of the tub.
  • the feeding device has a nozzle for introducing the water into the washing drum. This embodiment allows for spraying and / or injecting the water into the laundry.
  • the washing machine may have a flooding system, but it does not need any for the above described process. Therefore, it may also be flooding system-free. It is preferably flooding system-free.
  • the washing machine can be a washing machine or a combination appliance such as a washer-dryer.
  • the term "washing machine” includes privately and commercially used devices.
