Definitions

  • the invention relates to a method for operating a washing machine according to claim 1. Furthermore, the present application relates to a washing machine for washing textiles according to claim 12.
  • the washing machine comprises a tub in which a washing drum is mounted so that it can rotate.
  • the washing machine also has a drum drive, by means of which the washing drum can be driven in rotation about its axis of rotation.
  • the washing machine also comprises a circulation pump, by means of which liquid in the tub can be circulated into the tub, the circulation pump being set up in such a way that the liquid can be conveyed onto textiles that are in the washing drum.
  • the circulation pump can in particular interact with a liquid line, by means of which the liquid conveyed by the circulation pump can be guided to an upper end of the washing drum, so that during operation of the circulation pump, the liquid, which is typically taken from near the bottom of the tub or at the bottom of the tub, can be guided from above onto the textiles in the washing drum.
  • the washing machine also comprises at least one fill level sensor. This is suitable for detecting information relating to the fill level of the tub with liquid. In order to process this information, the washing machine also has a control device which is connected to the fill level sensor in a data-transmitting manner, so that the recorded information can be transmitted to the control device and processed by it.
  • the present application is based on the object of being able to determine the volume flow of liquid expelled from the textiles more reliably.
  • the method according to the invention is carried out as follows:
  • the washing drum is driven to rotate about its axis of rotation. This can be done in particular in such a way that the washing drum has a constant base speed.
  • the circulation pump is operated so that liquid in the suds container is pumped onto the textiles. This operating state is maintained until the fill level of the suds container reaches a previously defined value.
  • the fill level is monitored by means of the fill level sensor, which records the corresponding information.
  • the information is continuously recorded using the fill level sensor.
  • continuous means recording the information at a specific sampling frequency.
  • the latter is advantageously at least 50 Hz, preferably at least 100 Hz.
  • the circulation pump is switched off.
  • the defined value that leads to this break can be, for example, 0 mm water column.
  • the circulation pump is therefore only switched off after all the liquid in the suds container has been pumped onto the textiles by the circulation pump, so that there is no more liquid in the suds container.
  • the defined fill level value after which the circulation pump is switched off, corresponds to the suds container being filled with a certain volume of liquid that is different from zero. The washing drum is rotated at its base speed until the circulation pump is switched off.
  • switching off the circulation pump "after reaching the defined value” can mean, on the one hand, an immediate switch-off at the moment the defined value is reached.
  • the circulation pump is only switched off after a certain grace period after the defined value is reached, for example after a few seconds. It is therefore conceivable that the filling level of the lye container reaches the defined value, for example 0 mm water column, and the circulation pump is only switched off five seconds after this point in time, for example.
  • the washing drum continues to rotate, and because the circulation pump is no longer active, the liquid expelled from the textiles gradually collects in the suds container.
  • the speed of the washing drum is increased from the base speed to a higher expulsion speed after the circulation pump is switched off.
  • the washing drum can therefore be driven at the expulsion speed, for example, for the duration of a defined expulsion period over which the volume flow is to be determined.
  • the base speed can be 400 rpm and the higher expulsion speed can be 500 rpm.
  • the filling level sensor While the washing drum is being rotated in the manner described, information regarding the filling level of the suds container is recorded by means of the filling level sensor. This information is sent to the control device and processed by it. The volume flow of the expelled liquid is then determined. For this purpose, the information from the filling level sensor is processed, whereby, for example, a respective filling level of the suds container can correspond to a known volume of expelled liquid.
  • the connection between the filling level and the volume of the expelled liquid that is in the suds container when the filling level is present is given by a geometry of the suds container. Since this geometry is known, the volume of the expelled liquid can be derived directly from a respective recorded filling level.
  • the volume of the expelled liquid can be represented as a function of the filling level of the suds container with liquid. Furthermore, it is conceivable that the volume of the liquid present in the suds container is known for at least one defined filling level that is recorded by means of at least one filling level sensor. Preferably, the information that a certain volume of liquid is present in the lye container at a defined filling level is known for several different filling levels, wherein the different filling levels can be detected or are detected by means of different filling level sensors or by means of a single filling level sensor. The volume of the liquid expelled corresponds to the difference between the volumes of liquid in the lye container that were present at the two filling levels.
  • the method according to the invention has many advantages. In particular, it is not necessary, as in the prior art, to increase the speed of the washing drum to a very high level for a long time (in the prior art, over 1000 rpm is regularly required). Instead, the volume flow of the expelled liquid can basically be determined using a much lower base speed of the washing drum, for example 350 rpm.
  • the invention also provides for the case that only a comparatively small volume flow emerges from the textiles at the base speed. This can be the case in particular if the washing drum is only filled with a small amount of textiles, for example 1 kg or 2 kg. In this case, as described, the speed of the washing drum is increased - preferably temporarily - to the expulsion speed, so that the volume flow is increased.
  • the connection here is that the higher the speed of the washing drum, the more liquid escapes from the textiles, i.e., the greater the volume flow.
  • the expulsion speed is preferably still well below the values that are usual in the state of the art, so that the mechanical load on the components of the washing machine is reduced, as are the noise emissions from the washing machine during the process. If necessary, the expulsion speed can also be well beyond 1000 rpm, for example 1600 rpm.
  • the expulsion period extends between two points in time at which the volume of liquid with which the lye container was filled is known.
  • a first point in time can in particular be the point in time at which the circulation pump is switched off, at which, according to the above explanation, the filling level of the lye container can be, for example, 0 mm water column.
  • the second point in time can in particular be a point in time at which a specific filling level of the lye container, other than zero, is detected by means of the at least one filling level sensor.
  • the volume that was expelled from the textiles during the expulsion period corresponds to the volume that results from the filling level detected by means of the filling level sensor at the second point in time.
  • the duration of the expulsion period advantageously corresponds to the time difference between the two points in time mentioned. This means that all values for the division of the volume by the duration of the expulsion period described above are known, so that the average volume flow of the expelled liquid can be determined.
  • the points in time that define the beginning and end of the expulsion period are those at which the filling level of the lye container with liquid has reached a previously defined value.
  • This procedure has the advantage that the volume of the expelled liquid can be determined particularly easily for known filling levels, since the filling levels whose values are determined can be linked to volumes of liquid in the lye container. This can be done in particular by filling the lye container with liquid up to a respective filling level in advance, whereupon the volume of the liquid let into the lye container is measured (“calibration"). This can of course also be determined digitally using appropriate design models.
  • the volume of the liquid expelled over the duration of the expulsion period is determined based on fill levels that existed at the times between which the expulsion period extends.
  • the fill levels correspond to a filling of the lye container with a certain volume of liquid.
  • the fill levels are not determined in advance, the attainment of which defines the expulsion period, but the expulsion period is determined conversely, i.e. the two points in time that define the start and end of the expulsion period.
  • the fill level of the lye container with liquid is determined using at least one fill level sensor, with the fill levels each corresponding to a volume of liquid that was in the lye container at the respective points in time.
  • the volume of the liquid expelled in the expulsion period is the difference between the volumes of the liquid at the start and end of the expulsion period.
  • the duration of the expulsion period is also known (time difference between the start and end of the expulsion period), so that all values for determining the average volume flow are available.
  • both the beginning and the end of the expulsion period are selected such that the washing drum is rotated at the expulsion speed during the entire expulsion period.
  • the volume flow of the liquid that comes out of the textiles is as large as possible and can be measured accordingly.
  • the method comprises a preparation section which, in the structure of claim 1, is carried out chronologically before the first-mentioned method step a).
  • the method steps mentioned in claim 1 can be regarded as belonging to a measuring section of the method in the sense of the present application, whereby - if present - the preparation section is carried out chronologically before the measuring section.
  • the speed of the washing drum can be increased to the base speed before the circulation pump is switched on.
  • the washing drum is gradually accelerated from a starting value, for example 300 rpm, whereby liquid is expelled from the textiles due to the circulation pump being switched off and collects in the tub.
  • the speed is increased until a previously defined value of the filling level of the suds container is detected by the filling level sensor. As soon as this value is reached, the speed of the washing drum is no longer increased. The speed then reached forms the "base speed" of the process. The circulation pump is then activated so that the measuring section of the process can begin.
  • a mass of all textiles in the washing drum is determined. This can be done in particular using a mass inertia method, whereby the mass of the textiles is preferably determined while they are in a dry state.
  • the parameter of the mass of the textiles, preferably in a dry state, can also be used as an input parameter for further evaluations.
  • the ejection speed is automatically selected by the control device depending on the mass of all the textiles in the washing drum.
  • the application of the method is particularly useful when there is only a small mass of textiles in the washing drum.
  • the extent to which the speed of the washing drum should be increased from the base speed, i.e. the amount by which the ejection speed should be, is preferably made dependent on the mass of textiles present. The rule here is that the lower the mass, the higher the ejection speed.
  • the automatic selection of the ejection speed for example according to a previously defined function between the mass of textiles and the ejection speed, is particularly useful so that the washing machine can be operated optimally regardless of the user.
  • an inlet sensor can be formed, for example, by an impeller meter, by means of which a volume of liquid introduced into the lye container is detected. This makes it known how much liquid is in the lye container in total while the method is being carried out.
  • the expulsion speed is automatically selected by the control device depending on the amount of liquid. This procedure follows the consideration that if a small amount of liquid is introduced into the tub, the volume flow of liquid expelled from the textiles will probably also be small and therefore more difficult to measure.
  • the extent to which the speed of the washing drum should be increased from the base speed, i.e. the amount by which the expulsion speed should be, is therefore preferably made dependent on the amount of liquid present. The smaller the amount, the greater the expulsion speed.
  • the automatic selection of the expulsion speed for example according to a previously defined function between the amount of liquid and the expulsion speed, is particularly useful so that the washing machine can be operated optimally regardless of the user.
  • the expulsion speed is automatically determined by the control device depending on both the amount of liquid introduced into the tub and the mass of all the textiles in the washing drum. This means that the expulsion speed is automatically determined individually for each individual case, so that the average volume flow can be determined particularly reliably.
  • the function of the expulsion speed depending on the mass of the textiles and the amount of liquid can be determined in advance using empirical studies.
  • the control device of the washing machine according to the invention is intended and designed to operate the drum drive and the circulation pump depending on the information detected by the fill level sensor in such a way that the method steps of the method according to the invention are carried out.
  • the washing machine is therefore particularly well suited to carrying out the method according to the invention.
  • the advantages resulting from this have already been explained above.
  • a volume flow of liquid expelled from the textiles in the washing drum over the duration of an expulsion period can be determined particularly reliably, even if the mass of textiles in the washing drum is comparatively small.
  • the washing machine is particularly advantageous if it has at least one inlet sensor for detecting information about the amount of liquid introduced into the tub.
  • the inlet sensor can be designed in particular to determine the volume of all liquid introduced into the tub.
  • the inlet sensor can be formed by an impeller counter, for example.
  • such a washing machine can be advantageous in which at least one level sensor is formed by a pressure sensor or a contact sensor.
  • the level sensor is designed as a pressure sensor, it can preferably be assigned to a base of the suds container, i.e. act in particular in the base of the suds container.
  • a hydraulic pressure of liquid in the suds container can be determined using the level sensor, which makes it possible to determine a fill level of the suds container measured from the base.
  • the level of the suds container can be determined particularly well using such a level sensor. Knowing the geometry of the suds container, the volume of liquid in the suds container can also be determined using this information.
  • the fill level sensor is formed by a contact sensor, it is advantageous if it is arranged at a vertically measured distance from the bottom of the lye container.
  • the information from the fill level sensor can be interpreted to mean that at the moment the fill level sensor comes into contact with liquid, the lye container is filled with a certain volume of liquid, which corresponds to a filling level of the lye container with liquid that corresponds to the distance of the fill level sensor from the bottom of the lye container.
  • the volume of the liquid in the lye container is known in this way.
  • the washing machine comprises a plurality of fill level sensors which are arranged at different distances from the bottom of the tub.
  • the times can be defined in particular by the fact that the fill level sensors came into contact with the liquid for the first time. From this, it can be concluded that the suds container is or was filled with a volume of liquid at these times that corresponds to a fill level of the suds container that corresponds to the distance of the respective fill level sensor from the bottom of the suds container.
  • the fill level sensors are particularly well suited to defining the start and end of the expulsion period, while the volumes that correspond to the recorded fill levels are particularly well suited to determining the volume that was expelled from the textiles during the duration of the expulsion period.
  • the fill level sensors are preferably formed by contact sensors.
  • FIG. 1 An example of implementation that can be found in the Figures 1 and 2 , comprises a washing machine 1 which comprises a tub 2 and a washing drum 4 which can be driven in rotation within the tub 2.
  • the washing drum 4 is mounted so as to be driven in rotation about an axis of rotation 3 , wherein the washing drum 4 can be driven in rotation by means of a drum drive not shown in the figure.
  • Textiles 6 which are to be washed by means of the washing machine 1 are stored in the washing drum 4 .
  • the washing machine 1 also comprises a circulation pump 5 , which is provided and set up to direct liquid in the suds container 2 to the textiles 6 in the washing drum 4.
  • the circulation pump 5 interacts with a liquid line 7 , which directs the circulated liquid to an upper end of the washing drum 4 , so that the circulated liquid can fall from above onto the textiles 6.
  • a nozzle (not shown in the figure) can be arranged at an end of the liquid line 7 facing away from the circulation pump 5. The liquid is sucked out of the suds container 2 by means of the circulation pump 5 in the area of the bottom 13 of the suds container 2 , so that the circulation pump 5 can remove all of the liquid in the suds container 2 from the suds container 2 .
  • the washing machine 1 also comprises a supply line 14 , by means of which liquid can be introduced into the tub 2 from a liquid supply not shown in the figure, wherein a pump 15 is provided in the example shown to convey the liquid into the tub 2.
  • a pump 15 is provided in the example shown to convey the liquid into the tub 2.
  • an inlet sensor 10 is arranged in the supply line 14 , which is formed here by an impeller meter. The inlet sensor 10 is therefore suitable for detecting information relating to a volume of liquid introduced into the tub 2 .
  • the washing machine 1 also includes a fill level sensor 8. This is assigned to the bottom 13 of the suds container 2.
  • the fill level sensor 8 is formed here by a pressure sensor, which is intended and set up to continuously record information relating to a hydraulic pressure present on a sensor surface, which acts on the pressure sensor in the form of a water column.
  • the recorded hydraulic pressure directly results in a height of a liquid level of the liquid within the suds container 2 , at which the liquid is at a particular point in time. In other words, this results in the fill level of the suds container 2.
  • This information is sent to a control device 9 of the washing machine 1 , so that the control device 9 can use the information detected by the fill level sensor 8 to control the operation of the washing machine 1.

  • a mass of all textiles 6 that are in the dry state in the washing drum 4 is first determined using an inertia method before liquid is introduced into the suds container 2.
  • the washing drum is loaded with 2.0 kg of laundry. Liquid is then let into the suds container 2 through the supply line 14 using the pump 15. The volume of the total liquid introduced is recorded using the inlet sensor 10.
