Definitions

  • the invention relates to a method for operating a washing machine and a washing machine.
  • the invention relates to a method for operating a washing machine with a suds container arranged in a housing, in which a drum is rotatably mounted, a loading opening arranged on the front of the housing, which can be closed with a door having a door inspection glass, a suds container located between the housing and the Suds container to the loading opening extending door seal and a control and or regulating device and a correspondingly trained washing machine.
  • the method includes carrying out a selected washing program, which includes a rinsing phase and in which, following the rinsing phase, water is applied to the door sight glass and the door sealing ring in order to rinse the door sight glass and the door sealing ring.
  • a selected washing program which includes a rinsing phase and in which, following the rinsing phase, water is applied to the door sight glass and the door sealing ring in order to rinse the door sight glass and the door sealing ring.
  • a selected washing program which includes a rinsing phase and in which, following the rinsing phase, water is applied to the door sight glass and the door sealing ring in order to rinse the door sight glass and the door sealing ring.
  • Another washing machine that performs a rinsing and drying process to wash the door sight glass and the door seal of the washing machine door is from the document CN 107 604 585 A known.
  • the invention therefore faces the problem of providing a method and a washing machine with which foam in front of the door inspection glass and/or in the inner drum can be flushed away independently of the load quantity of a washing program. According to the invention, this problem is solved by a method having the features of patent claim 1 and a washing machine having the features of patent claim 10 .
  • the following step is provided in the method: Carrying out a spin cycle after the rinsing phase and before applying the water to the door sight glass and the door sealing ring with a maximum speed depending on the selected washing program.
  • the step according to the invention pushes the laundry out of the area of the door inspection glass and the door sealing ring, depending on the selected washing program, so that the water applied to the door inspection glass and the door sealing ring can touch the foam and is not sucked up by the laundry in the drum.
  • the method has the following steps: determining whether the wash program has a threshold load that exceeds a predetermined maximum load and/or is a voluminous laundry wash program and carrying out the spin cycle after the rinsing phase and before applying the water on the door sight glass and the door sealing ring at a maximum speed depending on whether the wash program has the threshold load amount that exceeds the predetermined maximum load amount and/or is the bulky laundry wash program.
  • the predetermined maximum load is a load of 2 kg.
  • the maximum speed is preferably 600 min -1, more preferably 550 min -1. It has been found that it is only necessary to carry out the spin cycle at the maximum speed if the wash program has a threshold load that exceeds the predetermined maximum load and/or is a bulky laundry wash program.
  • a bulky laundry washing program is a washing program for washing bulky laundry such as pillows, down and/or terry goods.
  • the threshold loading quantity is a maximum permissible loading quantity for each individual wash program.
  • the threshold loading quantity can vary from washing program to washing program and is assigned to each washing program and stored in the washing machine.
  • the spin process is preferably carried out at the maximum speed and then water is applied to the door inspection glass and/or the door sealing ring in order to Rinse the door sight glass and the door sealing ring.
  • the spin cycle is carried out at maximum speed between the rinsing phase and the application of the water to the door sight glass and the door sealing ring.
  • the purpose of the spinning process after the rinsing phase and before applying the water to the door sight glass and the door sealing ring at a maximum speed is to displace the laundry from the door sight glass as far as possible and to expose the foam, which usually does not change with the spin cycle. After exposing the foam, the door sight glass and the door sealing ring are rinsed by applying water.
  • the door sight glass and door seal ring are flushed with water, so the foam that collects there is washed away without the need for additional agents. Rather, already existing components of the washing machine can be used to remove the foam from the door sight glass and the door sealing ring.
  • the application of water preferably includes spraying or splattering at least part of the door sight glass and the door sealing ring.
  • the water can be applied to one or more points of the door sight glass and the door sealing ring.
  • the water is applied to the door sight glass and the door sealing ring by flushing the door sight glass. This allows the water to be applied directly to the door sight glass or door seal.
  • the door sight glass flushing device has a nozzle that squirts or sprays the water onto the door sight glass and the door sealing ring.
  • the method is preferably carried out as follows in this respect: The method preferably has the following steps: sensing a load of laundry in the drum in an initial phase of the washing program and linear or stepwise setting of the maximum speed during the spinning process as a function of the sensed load . Alternatively or additionally, the method has the following steps: sensing foam in the drum at the end and/or following the rinsing phase and linear or gradual adjustment of the maximum speed during the spin process depending on the foam sensing. This means that the centrifugal process can be regulated and/or controlled as a function of the sensed load quantity and/or the foam sense. In the case of a relatively low sensed load quantity, the maximum speed of the spinning process is preferably set linearly.
  • the speed of the spinning process is preferably increased in stages to the maximum speed of the spinning process.
  • the maximum speed is preferably 600 min -1, more preferably 550 min -1. At this maximum speed, it is avoided that more foam is whipped up, and the laundry is also pressed against the drum wall, but does not collapse again when the drum stops.
  • a foam sensing is for example from the DE19839896A1 or DE4104151A1 known.
  • the drum is stationary while the water is applied to the door sight glass and/or door seal to rinse the door sight glass and door seal.
  • a speed of rotation of the drum during the application of the water to the door sight glass and the door sealing ring is therefore 0 min -1 . That is, the drum is not rotated during the application of water to the door sight glass and door seal. This allows the applied water to carry the foam towards the drain.
  • a drainage device for draining the water out of the tub is permanently activated. This removes the water and foam from the tub and prevents it from contaminating the laundry.
  • the drainage device for draining the water out of the tub is activated if a pressure in the tub is sensed that is greater than a predetermined threshold.
  • the predetermined threshold is preferably chosen such that the sensed pressure corresponds to no higher than a water level that is at a bottom edge of the drum. This is intended to prevent the foam from being able to rise again into an area that is visible to a user of the washing machine, such as the door inspection glass.
  • an amount of water applied to the door sight glass and the door seal to flush the door sight glass and the door seal corresponds to a predetermined amount of water carried out by the washing program depends. This may be necessary if a specific total amount of water in the washing program should not be exceeded.
  • an amount of water applied to the door sight glass and door sealing ring to rinse the door sight glass and door sealing ring depends on the sensed load amount, sensed foam and/or an amount of an automatically dosed detergent that is used during the Washing program is fed to the tub.
  • the amount of water applied to the door sight glass and the door sealing ring is therefore adapted to the washing process, to an actual amount of foam and/or to automatic detergent dosing. This ensures that the foam can actually be flushed away and that an optimal amount of water is used, ie neither too much nor too little water is used for rinsing.
  • the selected wash program preferably has the following sequence: First, the load quantity is determined in a detection phase using a mass inertia method or a weight measurement. A washing phase is then carried out with supplying water and optionally detergent into the tub, heating the water to a predetermined washing temperature, washing the laundry and pumping the water out of the tub using the drain device. A rinsing phase is then carried out with a rinsing section or a plurality of rinsing sections, each comprising feeding water into the tub and pumping the water out of the tub by means of the drain device. The spin cycle is then carried out at the maximum speed depending on the wash program selected. Then, application of water to the door sight glass and the door seal ring is performed to rinse them. A final spin phase is then carried out with the laundry being spun until it comes into contact with the drum casing while water is pumped out of the tub using the drain device.
  • the invention also relates to a washing machine with a suds container arranged in a housing, in which a drum is rotatably mounted, a loading opening arranged on the front of the housing, which can be closed with a door having a door inspection glass, a suds container located between the housing and the suds container around the loading opening extending door sealing ring and a regulating or control device which is set up to regulate or control a method according to one or more of the described embodiments.
  • the washing machine preferably has a door sight glass flushing system.
  • the flushing of the door sight glass is preferably provided in and/or on the door sealing ring.
  • the flushing of the door sight glass is a spraying device like a nozzle and/or an opening in a door sealing ring designed as a bellows seal or as an elastic sleeve.
  • the washing machine can be a washing machine used in a private household or commercially.
  • the term "washing machine” preferably includes a washing machine and/or a combination device such as a washer-dryer.
  • step 1 schematically shows a flowchart of a method according to the invention.
  • step 1 a last rinsing section of a rinsing phase of a selected washing program is carried out.
  • step 2 in which the method according to the invention starts.
  • step 3 which includes determining whether the wash program has a threshold load that exceeds a predetermined maximum load, such as 2 kg, and/or is a bulky laundry wash program.
  • step 3 is followed by step 4, which involves performing a spin cycle with a Has a maximum speed of 600 min -1 , and step 4 is followed by a step 5.
  • step 3 If it is determined in step 3 that the washing program has a threshold loading quantity that is less than or equal to the predetermined maximum loading quantity and is a different washing program for each bulky laundry washing program, then step 3 is followed directly by step 5.
  • Step 5 comprises applying water to a door sight glass and a door seal of a washing machine to rinse them, with a drum of the washing machine standing still while the water is applied to the door sight glass and/or the door seal.
  • step 6 which has a final spin.
  • the drum is rotated at a higher speed than in step 4, at which the laundry rests against a casing of the drum and the water from the laundry due to centrifugal force from the fabric from the inside of the drum into the Suds container is thrown through openings in the drum.
