Definitions

  • the disclosure relates to a method for adapting a drying level of a drying program for a textile treatment appliance, a method for running a drying program, and a textile treatment appliance.
  • US20020184789A1 discloses a dryer in which the drying result can be adapted by correcting the time.
  • EP3342924A1 discloses a dryer in which users can make changes via the display for each preset residual moisture level. These changes are made before the start of the drying program.
  • the object of the present disclosure is to provide an improved method for adapting a drying level of a drying program for a textile treatment appliance, an improved method for running the drying program, and an improved textile treatment appliance.
  • this object is achieved by a method for adapting a drying level of a drying program for a textile treatment appliance, a method for running the drying program, and a textile treatment appliance having the features of the main claims.
  • the advantages that can be achieved with the disclosure are that the residual moisture levels in the textile treatment appliance, or the drying result, can be optimized with regard to the individually perceived residual moisture values at the end of the drying program and tailored to the operator.
  • the residual moisture levels can be automatically adapted after a user input. In this way, the residual moisture levels can be corrected on the basis of operator feedback. This makes it possible to tailor a drying level to the subjective perception of the operators.
  • a method for adapting a drying level of a drying program for a textile treatment appliance, wherein the drying level defines a level of residual moisture in textiles at the end of the drying program comprises the following steps:
  • the textile treatment appliance can be designed as a washer-dryer or a tumble dryer and is used to treat textiles, in particular to dry textiles.
  • the textile treatment appliance is designed to be able to run at least one drying program which can be started by an operator for drying textiles that have been inserted into the textile treatment appliance.
  • the drying level of the drying program can indicate the level of residual moisture up to which the textiles are to be dried.
  • the drying level can thus also be referred to as a residual moisture level.
  • a drying level can be preset for the drying program or the operator can be offered a range of options for selecting a drying level from a plurality of predetermined drying levels. Different drying levels can define different levels of residual moisture at the end of the drying program.
  • the drying levels “closet dry” and “extra dry” can be selected.
  • the level of residual moisture can represent the mass of liquid that is in the textiles, based on the dry weight.
  • the level of residual moisture that can be achieved by running the drying program can be controlled by means of the residual moisture parameter that is assigned to the drying level. If the residual moisture parameter assigned to a drying level is changed, the residual moisture of the textiles also changes if the drying program is run with this drying level.
  • the residual moisture parameter can represent the absolute value of the residual moisture to be achieved, a duration of the drying program or a parameter in an algorithm for controlling the drying program.
  • the output device can comprise a display, for example.
  • the question signal is, for example, suitable for controlling the output device in such a way that the output device outputs the question about the satisfaction of the level of residual moisture in a representation that is suitable for perception by the operator.
  • This allows the operator to be asked to provide feedback on their satisfaction.
  • the input device can have a touch-sensitive surface, a button, or a microphone for receiving speech.
  • the drying level can be adapted taking into account the operator's assessment of the level of residual moisture, in such a way that the level of residual moisture meets the operator's expectations when the drying program is run again, for example with the same drying level.
  • the adaptation can be carried out by adapting the residual moisture parameter assigned to the drying level.
  • the drying level can define a changed level of residual moisture in the textiles at the end of the drying program. If the operator has selected the same drying level when the drying program is restarted, a changed level of residual moisture can nevertheless be achieved by adapting the residual moisture parameter.
  • the residual moisture parameter of the drying level can be changed by a first value if the response signal represents too damp textiles as the assessment. Changing the parameter by the first value can have the effect that, when the drying program is run again with the drying level, the level of residual moisture is lower than in the case of the drying program just run. Accordingly, in the adapting step, the residual moisture parameter of the drying level can be changed by a second value if the response signal represents too dry textiles as the assessment. Changing the parameter by the second value can have the effect that, when the drying program is run again with the drying level, the level of residual moisture is greater than in the case of the drying program just run. To this end, the first value and the second value may have different signs.
  • the operator can choose between the response options “too damp” or “too dry”.
  • the textile cleaning appliance can learn the level of residual moisture that is appropriate for the operator and adapt the drying level accordingly.
  • the residual moisture parameter can be changed by means of the first value in such a way that the level of residual moisture defined by the drying level is reduced by a predetermined percentage, for example 1%.
  • the residual moisture parameter can be changed by means of the second value in such a way that the level of residual moisture defined by the drying level is increased by a predetermined percentage, for example 1%.
  • the residual moisture parameter of the drying level can be changed by a further first value in order to further reduce the level of residual moisture if the response signal represents too damp textiles as the assessment. Accordingly, in the adapting step, the residual moisture parameter of the drying level can be changed by a further second value in order to further increase the level of residual moisture if the response signal represents much too dry textiles as the assessment.
  • the operator has a range of possible responses and can choose between “damp”, “too damp”, “dry”, or “too dry”, for example.
  • the textile cleaning appliance can adapt the appropriate level of residual moisture even better in this case, since the operator has a larger selection of possible responses when assessing the level of residual moisture.
  • the residual moisture parameter can be changed by means of the further first value in such a way that the level of residual moisture defined by the drying level is reduced by a predetermined further percentage, for example 2%.
  • the residual moisture parameter can be changed by means of the further second value in such a way that the level of residual moisture defined by the drying level is increased by a predetermined further percentage, for example 2%.
  • the residual moisture parameter of the drying level is not adapted if the response signal represents an expected level of residual moisture of the textiles as the assessment.
  • the operator chooses this assessment if they are satisfied with the level of residual moisture in the textiles.
  • the textile cleaning appliance does not adapt the drying level or the residual moisture parameter assigned to the drying level.
  • the residual moisture parameter of the drying level can only be adapted if the response signal and at least one previous response signal consistently represent a too low level of residual moisture or consistently represent a too high level of residual moisture as the assessment. This can prevent the drying level from changing in the event of the operator being dissatisfied a single time.
  • the drying level can be adapted only if the operator has chosen the same assessment, for example “too damp”, several times, for example.
  • the method can further comprise a step of storing the assessment of the response signal.
  • the assessments By storing the assessments, the operator's assessments submitted at the end of previous runs of the drying program can be taken into account when adapting the residual moisture parameter.
  • a counter which can be set in response to a read-in response signal.
  • the adapting step can be performed only when the counter has reached a predetermined counter value. Otherwise, the adapting step can be skipped.
  • the question signal can be provided to the interface to the output device, which is designed as a display device of the textile treatment appliance.
  • the output device which is designed as a display device of the textile treatment appliance.
  • the question signal can additionally or alternatively be provided to an interface of an external device.
  • the external device can be a mobile device, for example a smartphone.
  • the method can comprise a step of detecting an input by the operator using a touch-sensitive sensor or microphone, which input indicates the assessment.
  • the response signal can be determined in response to the input. In this way, the operator can submit their assessment of the level of residual moisture either manually or by voice control.
  • the method can comprise a step of running the drying program.
  • a door of the textile treatment appliance can be unlocked.
  • the step of providing the question signal can be performed in response to the unlocking.
  • the approach presented here further provides a control apparatus which is designed to perform, control, or implement the steps of a variant of a method presented here in corresponding devices.
  • the object on which the disclosure is based can also be achieved quickly and efficiently by means of this embodiment variant of the disclosure in the form of an apparatus.

  • the textile treatment appliance 100 is suitable for drying textiles 105 .
  • the textile treatment appliance 100 is designed to run a drying program.
  • a drying level is assigned to the drying program or different drying levels can be selected by an operator for the drying program. In this respect, the drying level defines a level of residual moisture in the textiles 105 at the end of the drying program.
  • the approach described makes it possible to adapt the level of residual moisture defined by the drying level or the drying levels in response to an assessment by the operator.
  • at least one residual moisture parameter of the drying level or of the drying levels is adapted if the operator's assessment indicates that the operator is dissatisfied.
  • a length of a drying time of the drying program can be controlled by means of the residual moisture parameter.
  • the textile treatment appliance 100 can be called a washer-dryer or a tumble dryer.
  • the operator wishes to have the textiles 105 dried in the textile treatment appliance 100 , usually after they have been washed. To this end, the operator puts the textiles 105 into a textile treatment container 110 of the textile treatment appliance 100 and starts a drying program with a drying level which defines the level of residual moisture of the textiles 105 . If the drying level has not yet been adapted by the operator, the textile treatment appliance 100 dries the textiles 105 with the factory settings, i.e., it targets a residual moisture assigned to the drying level at the factory. Once the drying program has been run, the operator is given the opportunity to assess the level of residual moisture present in the textiles 105 .
  • Such an assessment is used to adapt at least the drying level that was set during the drying program that was just run.
  • the level of residual moisture assigned to the drying level is adapted, for example increased or reduced, in accordance with the operator's assessment. If the operator is satisfied with the level of residual moisture, no adaptation is made.
  • the adaptation is made only if a plurality of assessments are available, from which a tendency can be identified as to whether the textiles appear rather too dry or too damp from the operator's point of view.
  • a process for adapting the drying level is started as soon as the actual drying program has ended and the door of the textile treatment container 110 is unlocked.
  • the operator is then asked to submit an assessment of the level of residual moisture of the textiles 105 .
  • the question of whether the operator is satisfied with the level of residual moisture in the textiles 105 appears on an output device 115 of the textile treatment appliance 100 , which is designed for example as a display.
  • the operator can now assess, for example via a touch display, whether the textiles 105 are too damp or too dry.
  • the operator can also respond by voice control.
  • Another option is to send the question to an external device 120 , such as an app on a smartphone, so that the operator does not have to respond directly after the drying program, but can also make an assessment via the app later when folding the laundry.
  • the external device 120 constitutes, for example, a mobile device which is coupled or can be coupled to the textile treatment appliance 100 via a communication interface.
  • the assessment is then stored temporarily, e.g., in a cloud, when the textile treatment appliance 100 is already in standby, and transmitted to the textile treatment appliance 100 when the textile treatment appliance 100 is switched back on.
  • the approach described therefore includes various options for how the operator can assess the level of residual moisture, it being possible for the operator to be given an option or for all options to be made available in parallel.
  • this gives the operator the opportunity to assess the residual moisture result after the drying program.
  • these assessments are stored and after frequent, for example five, poor assessments, the drying level, or alternatively the drying levels, is adapted according to the operator's perception.
  • the textile treatment appliance 100 offers the operator the opportunity to choose different drying levels during drying.
  • the drying level “closet dry” is aimed, for example, at a laundry residual moisture of 0%.
  • the laundry residual moisture is a variable that is standardized to a given indoor climate.
  • the load is not dried 100% evenly, which means that if the total laundry residual moisture of the load is 0% there are items of laundry that are over dried and others that are still damp.
  • the operator's perception of whether the laundry is “dry” at a final residual moisture level of 0% is very subjective for these reasons. Often, the operator will perceive laundry with a final residual moisture level of 0% as “too damp”. However, the operator does not wish to select the drying level “closet dry” or “extra dry”, as they suggest that the laundry will be heavily stressed.
  • Preset drying levels are optimized, for example, to the standardized residual moisture variables, the level of residual moisture being made deliberately drier in some drying levels.
  • the operator is offered the opportunity to adjust the drying levels of the drying program using a programming function.
  • the level of residual moisture can thus be made up to 3% drier or damper for each drying level.
  • a corresponding adaptation is also carried out in an automated manner using the operator's assessments.
  • the approach described is aimed at automatically adapting the drying result to the operator.
  • the operator can subsequently adapt the drying level to their demands without too much complexity, since the assessment is made, for example, via a simple touch display or simple voice control.
  • the operator does not need to read an instruction manual to adapt the level of residual moisture assigned to a drying level.
  • the level of residual moisture can therefore be adapted on the basis of a satisfaction inquiry.
  • This adaptation would then be possible in the case of time drying by adapting the time or, in the case of table data, by adapting the values or, in the case of a linear model, by an offset.
  • a residual moisture parameter assigned to the drying level is adapted for such an adaptation.
  • the residual moisture parameter defines or influences, for example, the time of the time drying, at least one value of the table data or the offset of the linear model.
  • the residual moisture parameter is incorporated into a controller of the running of the drying program. If the level of residual moisture appears to the operator to be too low, the residual moisture parameter is adapted, for example, in such a way that the time of the time drying is shortened or a targeted residual moisture value is increased.

  • the input is made by touching one of the blocks of a touch-sensitive display that are indicated in FIG. 3 .
  • the response signal 140 thus represents an assessment of the operator with respect to satisfaction with the level of residual moisture.
  • the adaptation device 525 is designed to adapt a residual moisture parameter 530 of the drying level using the response signal 140 . Adapting the drying level has the effect that a changed level of residual moisture is targeted when the drying program is run again.
  • the adaptation device 525 is designed to change the residual moisture parameter 530 of the drying level by a first value if the response signal represents “too damp” textiles as the assessment, and to change it by a second value if the response signal represents “too dry” textiles as the assessment.
  • the first and the second value can, for example, cause the level of residual moisture assigned to the drying level to change by a predetermined first positive percentage and a predetermined first negative percentage, respectively.
  • the residual moisture parameter 530 is changed in a graduated manner according to an exemplary embodiment.
  • the residual moisture parameter 530 of the drying level is changed by a further first value if the response signal represents “much too damp” textiles as the assessment, and is changed by a further second value if the response signal represents “much too dry” textiles as the assessment.
  • the further first and the further second value can, for example, cause the level of residual moisture assigned to the drying level to change by a predetermined second positive percentage and a predetermined second negative percentage, respectively, which percentage is greater than the first percentage.
  • the adaptation device 525 is designed not to adapt the residual moisture parameter 530 in response to each response signal 140 , but only when both the last read-in response signal 140 and at least one previous response signal from a previous run of the drying program indicate a consistent assessment, for example “too damp” or “too dry”.
  • the adaptation device 525 is designed to store the assessment transmitted via the response signal 140 in a storage device 535 .
  • the storage device 535 comprises at least one counter which can store a number of corresponding assessments.
  • the adaptation device 525 is designed not to change the residual moisture parameter 530 if the response signal 140 indicates a level of residual moisture that is expected by the operator as the assessment, i.e., the operator is satisfied with the drying result.
  • the control apparatus 130 comprises a control device 540 which is designed to control the running of the drying program.
  • the control device 540 is designed to control the drying program using the residual moisture parameter 530 in such a way that the level of residual moisture defined by the drying level is achieved.
  • the control device 540 is designed to cause a door of the textile treatment appliance to unlock at the end of the drying program, and the providing device 505 is designed to provide the question signal 135 in response to the unlocking of the door.
  • control apparatus 130 constitutes a control unit of the textile treatment appliance or the control apparatus 130 is integrated into such a control unit.
  • FIG. 6 is a flowchart of a method 600 for adapting a drying level of a drying program for a textile treatment appliance, wherein the drying level defines a level of residual moisture in textiles at the end of the drying program.
  • the method can be carried out, for example, using the control apparatus described with reference to FIG. 5 .
  • the method 600 comprises a step 605 in which, at the end of the drying program, a question signal is provided to an interface to an output device.
  • the question signal causes a question to be output to the operator, which asks the operator about their satisfaction with the level of residual moisture in the textiles.
  • a response signal is read in via an interface to an input device.
  • the response signal indicates an assessment of the operator, input by the operator, with respect to their satisfaction with the level of residual moisture.
  • a residual moisture parameter of the drying level is adapted for a subsequent run of the drying program using the response signal.
  • the assessment indicated by the response signal is stored in a step 620 , for example using a counter.
  • the adapting step 615 is performed or skipped, for example depending on a value of the counter.
  • the method 600 optionally comprises a step 625 in which an input of the operator is detected and the response signal corresponding to the input is determined.
  • the method also comprises a step 635 in which the drying program is run, wherein a door of the textile treatment appliance is unlocked at the end of the drying program.
  • the step 605 of providing the question signal can be performed in response to the unlocking.
