Description

[0001] The present invention relates to a laundry care system with a control, in particular a laundry care system comprising a laundry care appliance with a control, and a method for caring for laundry in a laundry care system.

[0002] Laundry appliances often display a runtime forecast before starting a laundry program. In conventional laundry appliances, this forecast is typically based on the rated load of the laundry appliance. However, the average load of laundry for a laundry appliance user is often less than the rated load, especially for a laundry program for treating cotton.

[0003] As a result, conventional laundry care appliances often have an inaccurate, in particular too high, forecast of the running time of the laundry care program when the laundry care program starts.

[0004] It is the object underlying the invention to provide a laundry care system comprising a laundry care appliance and a method for caring for laundry in a laundry care system, with which the most efficient possible forecast of the running time of a laundry care program of the laundry care appliance can be achieved.

[0005] This object is achieved by the subject matter having the features according to the independent claims. Advantageous embodiments are the subject of the dependent claims, the description, and the drawings.

[0006] According to a first aspect, the object of the invention is achieved by a laundry care system, comprising: a laundry care appliance with a laundry chamber for receiving laundry and a controller, wherein a laundry care program with a first runtime forecast for treating a first laundry received in the laundry chamber is stored in the controller; a user interface which is connected to the controller, wherein the user interface is designed to receive the first runtime forecast from the controller and to display the first runtime forecast to a user before executing a first laundry care process; wherein the controller is designed to execute the laundry care program during the first laundry care process and to record a first runtime of the laundry care program after the first laundry care process;wherein the controller and / or an external controller outside the laundry care appliance is configured to determine, prior to execution of the laundry care program during a second laundry care process, a second runtime forecast for the second laundry care process of the laundry care program based on the first runtime forecast and the first runtime of the laundry care program; wherein the user interface is configured to receive the second runtime forecast from the controller and / or the external controller and to display the second runtime forecast to the user prior to execution of the laundry care program during the second laundry care process; and wherein the controller is configured to execute the laundry care program during the second laundry care process for treating second laundry accommodated in the laundry chamber.

[0007] This achieves the technical advantage that the runtime forecast for the second laundry care process, and in particular also for several laundry care processes following the second laundry care process, can be adapted to the actual runtime of the laundry care program. Furthermore, the runtime of the first laundry care process, in particular of the previous laundry care process in the case of several laundry care processes, can be included with a low weighting, so that there are no large jumps in the runtime forecast, even if a user of the laundry care appliance, for example for the first laundry care process, in particular the previous laundry care process, places laundry into the laundry chamber that has unusual properties, such as an unusually small or large quantity, an unusually small or large weight and / or unusually wet or unusually dry laundry.

[0008] The user interface can be an internal user interface of the laundry care appliance. The user interface can be an external user interface of the laundry care appliance, which is connected to the control of the laundry care appliance and / or the external control of the laundry care appliance outside the laundry care appliance via a communication interface and via a communication network.

[0009] A laundry care appliance is a device used for laundry care, such as a tumble dryer, washing machine, or washer-dryer, and which, in particular, has a drying function. In particular, such a laundry care appliance is understood to be a household laundry care appliance. That is, a laundry care appliance used in household management and with which laundry is treated in normal household quantities.

[0010] In one embodiment, the second laundry care process follows the first laundry care process. In particular, there is no further laundry care process based on the laundry care program between the first laundry care process based on the laundry care program and the second laundry care process based on the laundry care program.

[0011] In an advantageous embodiment, the first runtime forecast of the laundry care program is associated with a nominal load quantity associated with the laundry care program.

[0012] This provides the technical advantage that a simple base value can be used for the first runtime forecast.

[0013] In an advantageous embodiment, the user interface is designed to transmit a first assessment of the drying state of the first laundry to the controller and / or the external controller after the first laundry care process based on a first input from the user, wherein the controller and / or the external controller is designed to increase or decrease a second running time of the laundry care program during the second laundry care process by a predetermined running time fine adjustment value based on the transmitted first assessment of the drying state of the first laundry.

[0014] This achieves the technical advantage that, after the first laundry care process performed by the laundry care appliance, the control unit and / or the external control unit of the laundry care appliance can be informed, via the user interface, of an initial assessment of the dryness of the laundry by the user. This assessment enables the control unit and / or the external control unit to automatically and advantageously adjust the running time of the laundry care program for the second laundry care process following the first laundry care process in such a way that the user's expectations regarding the dryness of the laundry are met. This can enable more efficient laundry care by the user of the laundry care appliance.

[0015] The controller can, for example, be designed to trigger the first evaluation via the user interface when a door of the laundry care appliance opens, which allows the user access to the laundry compartment.

[0016] In an advantageous embodiment, the controller and / or the external controller is designed to determine the second runtime forecast for the second laundry care process of the laundry care program based on the first runtime forecast, the first runtime of the laundry care program and the predetermined runtime fine adjustment value.

[0017] This achieves the technical advantage that the runtime fine adjustment of the laundry care program caused by the user's first evaluation can also be used to determine the second runtime forecast.

[0018] In an advantageous embodiment, the controller and / or the external controller is designed to determine the result of a first function, in particular a linear multivariate function, in order to determine the second runtime forecast of the laundry care program, wherein in the first function the first runtime forecast and the first runtime are each weighted with a first weighting factor, and wherein the predetermined runtime fine adjustment value is weighted with a second weighting factor, wherein in particular the second weighting factor is greater, in particular twice as high, as the first weighting factor.

[0019] This provides the technical advantage that the second runtime forecast can be determined efficiently.

[0020] In an advantageous embodiment, the controller is configured to detect a second runtime of the laundry care program during the second laundry care process, wherein the controller and / or the external controller is configured to determine a third runtime forecast for the third laundry care process of the laundry care program based on the second runtime forecast and the second runtime of the laundry care program prior to executing the laundry care program during a third laundry care process; wherein the user interface is configured to receive the third runtime forecast from the controller and / or the external controller and to display the third runtime forecast to the user prior to executing the laundry care program during the third laundry care process; and wherein the controller is configured to execute the laundry care program during the third laundry care process for treating third laundry accommodated in the laundry chamber.

[0021] This provides the technical advantage that the runtime forecast can be continuously adjusted iteratively during subsequent laundry care processes.

[0022] In an advantageous embodiment, the user interface is designed to transmit a second assessment of the drying state of the second laundry to the controller and / or the external controller after the second laundry care process based on a second input from the user, wherein the controller and / or the external controller is designed to increase or decrease a third running time of the laundry care program during the third laundry care process by a predetermined running time fine adjustment value based on the transmitted second assessment of the drying state of the second laundry.

[0023] This achieves the technical advantage that, after the second laundry care process performed by the laundry care appliance, the control unit and / or the external control unit of the laundry care appliance can be informed, via the user interface, of a second assessment of the dryness of the laundry by the user. This assessment enables the control unit and / or the external control unit to automatically and advantageously adjust the running time of the laundry care program for the third laundry care process following the second laundry care process in such a way that the user's expectations regarding the dryness of the laundry are met. This can enable more efficient laundry care by the user of the laundry care appliance.

[0024] In one embodiment, the third laundry care process follows the second laundry care process. In particular, there is no further laundry care process based on the laundry care program between the second laundry care process based on the laundry care program and the third laundry care process based on the laundry care program.

[0025] In an advantageous embodiment, the controller and / or the external controller is designed to determine the third runtime forecast for the third laundry care process of the laundry care program based on the second runtime forecast, the second runtime of the laundry care program and the predetermined runtime fine adjustment value.

[0026] This achieves the technical advantage that the runtime fine adjustment of the laundry care program caused by the second user evaluation can also be used to determine the third runtime forecast.

[0027] In an advantageous embodiment, the controller and / or the external controller is designed to determine the result of a second function, in particular a linear multivariate function, in order to determine the third runtime forecast of the laundry care program, wherein in the second function the second runtime forecast and the second runtime are each weighted with a first weighting factor, and wherein the predetermined runtime fine adjustment value is weighted with a second weighting factor, wherein in particular the second weighting factor is greater, in particular twice as high, as the first weighting factor.

[0028] This provides the technical advantage that the third runtime forecast can be determined efficiently.

[0029] In an advantageous embodiment, the user interface comprises a touch-sensitive screen of the laundry care appliance, which is designed to detect the first and / or second input of the user for the first and / or second assessment of the drying state of the first and / or second laundry, wherein the touch-sensitive screen is designed to transmit the first and / or second assessment of the drying state of the laundry to the controller and / or external controller.

[0030] This provides the technical advantage that the user can evaluate the laundry directly on the laundry care device immediately after removing it from the laundry compartment.

[0031] In an advantageous embodiment, the user interface comprises a mobile user device, in particular a smartphone, smart pad, laptop or PC, which is connected to the controller and / or external controller via a communication network and is designed to detect the first and / or second input of the user for the first and / or second assessment of the drying state of the first and / or second laundry and to transmit the first and / or second assessment of the drying state of the first and / or second laundry to the controller and / or external controller.

[0032] This provides the technical advantage that the user can evaluate the laundry remotely from the laundry care device, for example, when placing the laundry on a piece of furniture. In particular, an app designed to communicate with the control unit and / or the external control unit can be run on the mobile user device.

[0033] In an advantageous embodiment, the laundry care appliance comprises an electronic memory which is designed to store a plurality of data records and a plurality of laundry care programs, wherein the plurality of laundry care programs comprises the laundry care program, wherein each of the laundry care programs of the plurality of laundry care programs is assigned at least one data record of the plurality of data records, wherein a data record of the plurality of data records which is assigned to the laundry care program comprises the first running time and the second running time, and in particular the third running time, and / or the first running time forecast and the second running time forecast, and in particular the third running time forecast.

[0034] This provides the technical advantage that a separate data set can be used for each laundry care program to enable efficient laundry care program-specific runtime forecasting.

[0035] In an advantageous embodiment, the controller and / or external controller is designed to determine a value that is associated with a change in the running times and / or running time forecasts of the data set associated with the laundry care program over a predetermined period of time, wherein the controller and / or external controller is designed to execute a program for automatically cleaning the laundry care appliance, in particular a filter of the laundry care appliance, depending on a comparison of the value with a reference value.

[0036] This provides the technical advantage of detecting changes in the laundry care program's runtime over the appliance's lifetime, indicating lint and / or dust accumulation. This can lead to efficient automatic maintenance of the laundry care appliance, particularly in heat-pump laundry care appliances.

[0037] The predetermined time period can, in particular, be a rolling time period, i.e., comprise a predetermined number of the most recently saved runtime forecasts and / or runtimes of the data set. The reference value can, for example, be a threshold value assigned to the value.

[0038] In an advantageous embodiment, the controller and / or external controller is designed to determine a value that is associated with a change in the running times and / or running time forecasts of the data set associated with the laundry care program over a predetermined period of time, wherein the controller and / or external controller is designed to determine user information as a function of a comparison of the value with a reference value, wherein the user interface is designed to display the user information to the user, wherein the user information comprises an instruction for manually cleaning the laundry care appliance, in particular a filter of the laundry care appliance, and / or for manually starting a program for automatically cleaning the laundry care appliance, in particular a filter of the laundry care appliance.

[0039] This provides the technical advantage of detecting changes in the laundry care program's runtime over the appliance's lifetime, indicating lint and / or dust accumulation. This can lead to efficient manual or semi-automatic maintenance of the laundry care appliance, particularly in heat-pump laundry care appliances.

[0040] The predetermined time period can, in particular, be a rolling time period, i.e., comprise a predetermined number of the most recently saved runtime forecasts and / or runtimes of the data set. The reference value can, for example, be a threshold value assigned to the value.

[0041] According to a second aspect, the object is achieved by a method for caring for laundry in a laundry care system, wherein the laundry care system comprises: a laundry care appliance with a laundry chamber for receiving laundry and a controller, wherein a laundry care program with a first runtime forecast for treating a first laundry received in the laundry chamber is stored in the controller; and a user interface which is connected to the controller; wherein the method comprises the following method steps: receiving the first runtime forecast from the controller and displaying the first runtime forecast to a user via the user interface before executing the laundry care program during a first laundry care process; executing the laundry care program during the first laundry care process for treating the first laundry received in the laundry chamber;Detecting a first runtime of the laundry care program after the first laundry care process by the controller; determining a second runtime forecast for the second laundry care process of the laundry care program based on the first runtime forecast and the first runtime of the laundry care program by the controller and / or the external controller before executing the laundry care program during a second laundry care process; receiving the second runtime forecast from the controller and / or the external controller and displaying the second runtime forecast to the user through the user interface before executing the laundry care program during the second laundry care process; and executing the laundry care program during the second laundry care process to treat second laundry received in the laundry chamber by the controller.

[0042] This achieves the technical advantage that the runtime forecast for the second laundry care process, and in particular also for several laundry care processes following the second laundry care process, can be adapted to the actual runtime of the laundry care program. Furthermore, the runtime of the first laundry care process, in particular of the previous laundry care process in the case of several laundry care processes, can be included with a low weighting, so that there are no large jumps in the runtime forecast, even if a user of the laundry care appliance, for example for the first laundry care process, in particular the previous laundry care process, places laundry into the laundry chamber that has unusual properties, such as an unusually small or large quantity, an unusually small or large weight and / or unusually wet or unusually dry laundry.

[0043] The embodiments mentioned for the laundry care system according to the first aspect are also embodiments for the method according to the second aspect.

[0046] Fig. 1 shows a schematic view of a laundry care appliance 100 according to an embodiment, such as a tumble dryer, a washing machine, or a washer-dryer. The laundry care appliance 100 may have an appliance housing 102 with an appliance opening 104, which can be closed by an appliance door 103 for loading the laundry care appliance 100. Through the appliance opening 104, a user of the laundry care appliance 100 can load laundry into a laundry basket arranged within the appliance housing 102 and in Fig. 1 introduce the laundry chamber 105, which is only shown schematically.

[0047] The laundry care appliance 100 comprises a Fig. 1 shows a control system 107, which is shown only schematically. The laundry compartment 105 of the laundry care appliance 100 is designed to accommodate laundry. A laundry care program with a first runtime forecast for treating a first load of laundry accommodated in the laundry compartment 105 is stored in the control system 107. The first runtime forecast of the laundry care program can be assigned to a nominal load quantity assigned to the laundry care program.

[0048] As in the Fig. As shown schematically in Figure 1, a user interface 101 of the laundry care appliance 100 may include a touch-sensitive screen via which a user of the laundry care appliance 100 can communicate with the controller 107 of the laundry care appliance 100, for example, to select and / or configure the laundry care program. The user interface 101 is connected to the controller 107.

[0049] The user interface 101 is configured to receive the first runtime forecast from the controller 107 and to display the first runtime forecast to a user prior to executing a first laundry care cycle. The controller 107 is configured to execute the laundry care program during the first laundry care cycle and to record a first runtime of the laundry care program after the first laundry care cycle.

[0050] Fig. 2 shows a schematic view of a laundry care system 200 comprising a laundry care appliance 100, a user interface 101, and an external controller 108 according to one embodiment. The laundry care appliance 100 of the Fig. The laundry care system 200 shown in Figure 2 corresponds in particular to the Fig. 1, except that the user interface 101 may be an external user interface outside the laundry care appliance 100.

[0051] The user interface 101 can be connected to the controller 107 and / or connected via a communication network 109 to an external controller 108 outside the laundry care appliance 100. As shown in the Fig. 2, the user interface 101 may comprise a mobile user device, in particular a smartphone, smart pad, laptop or PC.

[0052] The communication network 109 comprises, in particular, a wireless communication network 109. Both the laundry care appliance 100, the user interface 101, and the external controller 108 have communication interfaces for communication-technical connection to the communication network 109.

[0053] In accordance with the Fig. In the embodiment illustrated in Figure 2, the communication connection between the laundry care appliance 100 and the user interface 101, between the laundry care appliance 100 and the external controller 108, and also between the external controller 108 and the user interface 101 is achieved through the same communication network 109. In particular, however, different communication networks 109 can alternatively be used for the communication exchange of data between the laundry care appliance 100, the user interface 101, and / or the external controller 108.

[0054] The controller 107 and / or the external controller 108 outside the laundry care appliance 100 is configured to determine a second runtime forecast for the second laundry care process of the laundry care program based on the first runtime forecast and the first runtime of the laundry care program prior to executing the laundry care program during a second laundry care process.

[0055] The user interface 101 is configured to receive the second runtime forecast from the controller 107 and / or the external controller 108 and to display the second runtime forecast to the user prior to executing the laundry care program during the second laundry care process.

[0056] The user interface 101 can be configured to transmit a first assessment of the drying state of the first laundry to the controller 107 and / or the external controller 108 after the first laundry care process based on a first input from the user. The user interface 101, in particular the touch-sensitive screen of the laundry care appliance 100 and / or the mobile user device, can be configured to capture the first user input for the first assessment of the drying state of the first laundry.

[0057] The controller 107 and / or the external controller 108 can be configured to determine the result of a first function, in particular a linear multivariate function, in order to determine the second runtime forecast of the laundry care program. In the first function, the first runtime forecast and the first runtime can each be weighted with a first weighting factor, and the predetermined runtime fine adjustment value can be weighted with a second weighting factor. The second weighting factor can be greater, in particular twice as high, than the first weighting factor.

[0058] The controller 107 is configured to execute the laundry care program during the second laundry care process for treating second laundry received in the laundry chamber 105.

[0059] The controller 107 and / or the external controller 108 may be configured to increase or decrease a second running time of the laundry care program during the second laundry care process by a predetermined running time fine adjustment value based on the transmitted first assessment of the drying state of the first laundry.

[0060] The controller 107 can be configured to detect the second runtime of the laundry care program during the second laundry care process. The controller 107 and / or the external controller 108 can be configured to determine a third runtime forecast for the third laundry care process of the laundry care program based on the second runtime forecast and the second runtime of the laundry care program prior to executing the laundry care program during a third laundry care process.

[0061] The user interface 101 can be configured to transmit a second assessment of the drying state of the second laundry to the controller 107 and / or the external controller 108 after the second laundry care process based on a second user input. The user interface 101, in particular the touch-sensitive screen of the laundry care appliance 100 and / or the mobile user device, can be configured to capture the second user input for the second assessment of the drying state of the second laundry.

[0062] The controller 107 and / or the external controller 108 may be configured to increase or decrease a third running time of the laundry care program during the third laundry care process by a predetermined running time fine adjustment value based on the transmitted second assessment of the drying state of the second laundry.

[0063] The controller 107 and / or the external controller 108 may be configured to determine the third runtime forecast for the third laundry care process of the laundry care program based on the second runtime forecast, the second runtime of the laundry care program, and the predetermined runtime fine adjustment value.

[0064] The controller 107 and / or the external controller 108 can be configured to determine the result of a second function, in particular a linear multivariate function, in order to determine the third runtime forecast of the laundry care program. In the second function, the second runtime forecast and the second runtime can each be weighted with the first weighting factor, and the predetermined runtime fine adjustment value can be weighted with the second weighting factor.

[0065] The user interface 101 may be configured to receive the third runtime forecast from the controller 107 and / or the external controller 108 and to display the third runtime forecast to the user prior to executing the laundry care program during the third laundry care process.

[0066] The controller 107 may be configured to execute the laundry care program during the third laundry care process for treating third laundry accommodated in the laundry chamber 105.

[0067] In particular, in addition to determining the third runtime forecast, corresponding iterative determinations of further runtime forecasts for further laundry care processes of the laundry care appliance are possible. This is described below using a first example, in which the corresponding calculation examples are rounded.

[0068] The controller 107 and / or the external controller 108 may, for example, be configured to determine that the first runtime forecast is 200 minutes based on the nominal load of the laundry care program.

[0069] The controller 107 and / or the external controller 108 can, for example, be configured to determine the second runtime forecast for the second laundry care process as 155 minutes based on the first runtime forecast and the first runtime of the first laundry care process of the laundry care program, which is determined, for example, as 110 minutes, using the term “0.5 * 200 + 0.5 * 110”.

[0070] The controller 107 and / or the external controller 108 can, for example, be configured to determine the third runtime forecast for the third laundry care process as 130 minutes based on the second runtime forecast and the second runtime of the second laundry care process of the laundry care program, which is determined, for example, as 105 minutes, using the term “0.5 * 155 + 0.5 * 105”.

[0071] The controller 107 and / or the external controller 108 can, for example, be configured to determine a fourth runtime forecast for a fourth laundry care process as 133 minutes based on the third runtime forecast and the third runtime of the third laundry care process of the laundry care program, which is determined, for example, as 135 minutes, using the term “0.5 * 130 + 0.5 * 135”.

[0072] The controller 107 and / or the external controller 108 can, for example, be configured to determine a fifth runtime forecast for a fifth laundry care process as 129 minutes based on the fourth runtime forecast and a fourth runtime of the fourth laundry care process of the laundry care program, which is determined, for example, as 125 minutes, using the term “0.5 * 133 + 0.5 * 125”.

[0073] A second example illustrates the inclusion of the runtime fine-tuning value, in which the corresponding calculation examples are rounded. The runtime fine-tuning value results in a predetermined extension of the laundry care program of 12 minutes. Of course, more or less than 12 minutes is also possible.

[0074] The controller 107 and / or the external controller 108 may, for example, be configured to determine that the first runtime forecast is 200 minutes based on the nominal load of the laundry care program.

[0075] The controller 107 and / or the external controller 108 can, for example, be configured to receive the user's first input, which is associated, for example, with an insufficient degree of dryness of the first laundry, i.e., the user indicates via the user interface 101 that the first laundry is too wet. The controller 107 and / or the external controller 108 can then be configured to determine the second runtime forecast for the second laundry care process as 167 minutes based on the first runtime forecast, the first runtime of the first laundry care process of the laundry care program, which is determined, for example, as 110 minutes, and the runtime fine adjustment value using the term "0.5 * 200 + 0.5 * 110 + 1 * 12".

[0076] The controller 107 and / or the external controller 108 can, for example, be configured to receive the second user input, which is associated, for example, with an insufficient degree of dryness of the second laundry, i.e., the user again indicates via the user interface 101 that the second laundry is too wet. The controller 107 and / or the external controller 108 can then be configured to determine the third runtime forecast for the third laundry process as 157 minutes based on the second runtime forecast, the second runtime of the second laundry care process of the laundry care program, which is determined, for example, as 122 minutes, and the runtime fine adjustment value using the term "0.5 * 167 + 0.5 * 122 + 1 * 12".

[0077] The controller 107 and / or the external controller 108 can, for example, be configured to receive an input from the user which, for example, is associated with a sufficient degree of dryness of the third laundry, i.e., the user indicates via the user interface 101 that the third laundry is perfectly dry. The controller 107 and / or the external controller 108 can, for example, be configured to determine the fourth runtime forecast for the fourth laundry process as 145 minutes based on the third runtime forecast and the third runtime of the third laundry care process of the laundry care program, which is determined, for example, as 134 minutes, using the term "0.5 * 157 + 0.5 * 134".

[0078] The controller 107 and / or the external controller 108 can, for example, be configured to receive an input from the user which, for example, is associated with a sufficient degree of dryness of the fourth laundry, i.e., the user here again indicates via the user interface 101 that the fourth laundry is perfectly dry. The controller 107 and / or the external controller 108 can, for example, be configured to determine the fifth runtime forecast for the fifth laundry care process as 140 minutes using the term "0.5 * 134 + 0.5 * 145" based on the fourth runtime forecast and a fourth runtime of the fourth laundry care process of the laundry care program, which is determined, for example, as 134 minutes.

[0079] This can lead to an alignment of the runtime forecast and the runtime itself, allowing the runtime forecast to be reduced, i.e., adjusted, even if the runtime temporarily increases. Furthermore, an extension of the laundry care program can be concealed by the runtime fine adjustment value.

[0080] Fig. Figure 3 shows, in a program runtime-time diagram 300, a curve 301 of runtimes of the laundry care program in successive laundry care processes of the laundry care system 200 according to one embodiment. The laundry care system 200 corresponds in particular to the Fig. 2 laundry care system 200 shown.

[0081] The chronologically successive laundry care processes can include, in this order, the first laundry care process, the second laundry care process, and especially the third laundry care process. The ordinate of the program runtime-time diagram 300 indicates the runtime of the laundry care program, and the abscissa of the program runtime-time diagram 300 indicates the chronological sequence of the laundry care programs.

[0082] The laundry care appliance 100 can comprise an electronic memory configured to store a plurality of data records and a plurality of laundry care programs. The plurality of laundry care programs can comprise the laundry care program. At least one data record from the plurality of data records can be assigned to each of the laundry care programs of the plurality of laundry care programs. A data record from the plurality of data records assigned to the laundry care program can comprise the first runtime and the second runtime, and in particular the third runtime, and / or the first runtime forecast and the second runtime forecast, and in particular the third runtime forecast.

[0083] As in the Fig. 3, the controller 107 and / or external controller 108 can be configured to determine a value 305a, 305b which is associated with a change in the running times of the data set associated with the laundry care program over a predetermined time period 303a, 303b.
