Definitions

  • the invention relates to a washing machine and a method for operating a washing machine.
  • Today's washing machines should wash gently.
  • a high energy efficiency with good washing performance is to be achieved.
  • This can be achieved by saving water in the washing phase and in the rinsing phases of a washing program.
  • the water saving results in a decrease in the proportion of free liquor relative to the bound liquor, the term "bound liquor” denoting wash liquor bound to the wash, and the term "free liquor” designating unbound wash liquor, i. washing liquid not bound to the laundry.
  • Due to the reduced proportion of free liquor occurs in the washing phase a heating cycle by faster reaching a desired target temperature of the free fleet and as a result, a delayed warming of the bound fleet.
  • an energetically not efficient liquor heating and thus a worse washing effect per time can be achieved.
  • homogeneous dishwashing results and need-based rinsing times are more difficult to achieve for smaller portions of free liquor.
  • a washing machine and a method for operating the washing machine are known in which it is possible to detect a temperature of the free liquor or of laundry to be washed as operating parameters and to send it to a control device.
  • a sensor unit is arranged in a drum or a tub of the washing machine.
  • the invention thus has the problem of providing a washing machine and a method for operating a washing machine, which have an optimized effect and duration of a washing program for washing laundry.
  • Direction and location information refers to the operational installation position of the washing machine.
  • washing liquid includes water optionally mixed with detergent.
  • the washing machine has a tub, a rotatably mounted in the tub drum with a hollow cylindrical drum shell, at least one arranged on the inside of the drum shell scoop and a non-contact temperature sensor, which is arranged in and / or on the scoop rib.
  • the non-contact temperature sensor is arranged in the scoop rib, but parts of the temperature sensor can protrude from the interior of the scoop rib.
  • the scooping rib is equipped with an inlet and has the task to absorb the accumulated in the lower portion of the tub, based on the operating position of the washing machine, accumulated washing liquid.
  • the washing liquid When rotating the drum, the washing liquid is raised above a level of the washing liquid in the lower portion of the tub and then rains down from outlet openings of the scoop on the laundry inside the drum down.
  • the laundry is sprinkled with the washing liquid by means of the pouring rib.
  • the contactless temperature sensor is in the context of the invention, a temperature sensor, which is cable and preferably also battery-free. It is designed to induce cable voltage and preferably also batteryless voltage in order to bring about a change in current.
  • the temperature sensor is formed and arranged in the scooping rib to measure a temperature of laundry located in the drum.
  • the non-contact temperature sensor may preferably measure a temperature of the laundry and transmit the measured temperature to a data recorder such as, for example, a storage, control and / or control device.
  • the data recorder is preferably arranged in the tub. If the contactless temperature sensor falls below a predetermined distance from the data recorder in a washing process, data is transferred automatically from the contactless temperature sensor to the data recorder.
  • At least one scoop rib is formed as a separate component and secured to the drum shell.
  • the scoop rib is more preferably formed as a bending part made of sheet metal open on the sides and fixed by means of a rabbet joint on the drum shell.
  • the scoop rib extends over the entire width of the drum shell.
  • the arrangement of the scoop rib as an open bending part a cavity between the bending part and the drum shell is formed.
  • the drum shell has inlet openings for introducing washing liquid into the cavity on. This allows the cavity to receive washing liquid from the lower portion of the tub when the scoop and wash liquid are at the bottom of the tub.
  • the bending part of the scooping rib has outlet openings through which the washing liquid can escape during rotation of the drum to sprinkle the laundry.
  • the non-contact temperature sensor is preferably arranged in the cavity such that it is inserted into an inlet opening of the drum shell and an opening disposed opposite the inlet opening in the bending part of the scoop rib.
  • the contactless temperature sensor can furthermore be fastened to the pouring rib or the drum casing by means of latching or screwing.
  • the contactless temperature sensor may have tabs, for example.
  • the non-contact temperature sensor is preferably a molded component. He is formed rod-shaped.
  • the non-contact temperature sensor protrudes from the drum shell and the scoop, so that it forms a protruding into the drum or the tub in each case projection to the scoop rib or the drum.
  • the end of the contactless temperature sensor projecting from the pouring rib preferably has a rounded shape. This minimizes potential damage to the laundry by the temperature sensor. Furthermore, the end of the contactless temperature sensor protruding from the pouring rib has a temperature sensor which can sense the temperature of the laundry in contact with laundry to be washed.
  • the protruding from the drum shell end of the contactless temperature sensor is preferably suitable for energy and data transmission. For example, it is designed for a punctual data transmission to a sensor arranged in the tub data recorder as a storage, control and / or control unit. The contactless temperature sensor can continue to absorb energy via its protruding from the drum shell end.
  • a thermistor in the tub is more preferably arranged in the lower region of the tub, based on the operating position of the washing machine.
  • the thermistor serves to measure a temperature of the free liquor.
  • the washing machine preferably has a control device which is designed to regulate a washing program selected by a user of the washing machine.
  • the control device is preferably set up to regulate a washing and / or rinsing duration on the basis of operating parameters which it receives from the contactless temperature sensor and, if appropriate, further sensors or their data sensors arranged further in the washing machine.
  • the washing machine may be a commercial or household use washing machine.
  • washing machine also includes washer-extractors and washer-dryers.
  • the method By measuring the temperature of the laundry and measuring the duration of the temperature applied in the laundry, the method enables on the basis of the measured values, i. Temperature and time in the laundry, the influence of procedural stored program parameters to achieve an energy-efficient washing process regardless of load and fleet level with consistently good washing effect.
  • the temperature of the laundry By measuring the temperature of the laundry and measuring the temperature of the washing liquid i. the temperature of the free liquor can be determined an equalizing temperature of the bound or free liquor. As a result, for example, a sufficient purging duration can be determined.
  • the step of measuring a duration of the temperature applied in the laundry is carried out in a washing phase.
  • the washing performance can be adjusted independently of the load of the washing machine with laundry and the level of the free liquor.
  • the step of measuring a temperature of the washing liquid is carried out in a rinsing phase of a washing program. It is thus possible to determine the optimum duration of the rinsing phase on the basis of the mixing temperature which arises and independently of the load state of the washing machine with laundry and the level of the free liquor. With a low level of the free liquor, in particular, the rinsing phases last longer until the temperature equilibrium is shorter, with a high level of free liquor. As a result, increased efficiency in terms of time and / or rinsing effect achieved.
  • a Washing phase duration determined by means of the measured temperature of the laundry and the measured duration of the applied temperature in the laundry.
  • a rinsing duration is determined by means of the measured temperature of the laundry and the measured temperature of the washing liquid.
  • the method is preferably suitable for washing and rinsing laundry with little water.
  • a supply of water in the tub in a washing phase and / or rinsing phase of a wash program is controlled so that the water supplied to be present in the drum laundry predominantly as bound liquor and only a small proportion of free liquor in the washing machine ,
  • the level of free liquor in the tub is preferably selected so that the cavity of the scoop rib can receive the free liquor so that the scoop can fulfill its function of sprinkling the wash with scrubbing liquid during rotation of the drum.
  • Fig. 1 shows a partial perspective view of a drum 1.
  • the drum 1 has a hollow cylindrical drum shell 2 with an inner side 21 and an outer side 22.
