EP2222912B1 - Laundry care appliance, and method for the operation of such a laundry care appliance - Google Patents

Description

The invention relates to a laundry care device having a storage unit and at least one operating program with a plurality of operating program parameters that can be selected and stored in the storage unit, and to a method for operating a laundry care appliance after selecting an operating program with a plurality of operating program parameters.

The washing of soiled laundry in a washing machine is carried out with an operating program with more or less fixed sequence. The operating program comprises several steps, whereby the achievement of the greatest possible washing success is achieved only by the optimum combination of mechanical and chemical parameters within a timed scheme and in the context of a temperature regime tailored to the type of laundry. The parameters time, chemistry, mechanics and temperature compensate each other to a certain extent, but can not be completely replaced.

Each operating program therefore includes specifications for the parameters time, chemistry, mechanics and temperature. If e.g. given a time frame for a laundry care passage, for example, one and a half hours for 60 ° C coloreds, so the remaining parameters must be adjusted to it, so that a satisfactory washing result is achieved. For example, the mechanism can be adjusted by adjusting the drum movement. At different speeds, a different mechanism acts on the laundry. The spin speed and dryer speed, as well as other settings, such as Reversiermodus etc., can be subsumed under the term mechanics.

The parameter chemistry, as a default operating parameter for a washing program, usually mainly comprises the amount of water. If an automatic dosing system is provided, the parameter chemistry naturally also includes the quantity the nature and combination and addition sequence of treating agents, such as detergents in general, detergents, etc.

The parameters time and temperature are self-explanatory operating parameters which are usually preset for certain operating programs in conventional washing machines (e.g., 60 ° C cooking / color takes a predetermined time).

Modern laundry care devices have a multiplicity of operating programs which have an optimal ratio of the above-explained operating parameters to one another. In conventional laundry care equipment, the user typically selects the type of laundry and temperature (e.g., 40 ° C easy care). The operating programs for delicate laundry, for example, keep the parameter mechanics as low as possible, since an excessive mechanical action on the laundry to be cleaned would lead to excessive stress on the fine fabrics. In return, however, the parameters of time and chemistry take greater effect here. The laundry items are cleaned more slowly over a longer period of time in a special wash liquor. Undemanding laundry, such as white cooking linen, on the other hand, is washed at high temperatures of up to 95 ° C without being damaged.

In addition to simplifying the operation of laundry care appliances, consumers also wish to be able to control laundry care individually and from an ecological and economic point of view. For example, conventional laundry care equipment already permits, to a limited extent, the adjustment of the operating program to the degree of soiling of the laundry. It can be adjusted within certain limits in almost all modern washing machines, the setting of the drum speed in the spin cycle, on the one hand to save by reducing the speed of the fabric and to consume less energy for the washing process, and on the other hand by increasing the speed of a better spin result achieve. The same applies to the option of selecting the washing temperature. Modern machines also allow the user to switch off the pre-wash cycle, which makes sense from an ecological and economic point of view, or to select short wash programs for washing less heavily soiled laundry.

Under an operating program we understand a program which is determined by the user-side setting of the operating parameters, with the setting predetermined operating parameters permanently assigned to the operating parameters specific to the selected operating program are selected. Operating programs also include subroutines that result from the user's setting of possible options for the selected operating program, or subroutines that are self-executable as part of an operating program. Such sub-programs could be, for example, a spin, pump down or soak program.

For even further intervention in the washing process provides the EP 0 898 003 A2 a multifunction washing machine control device with a display display with plain text displayable and selectable operating programs. The user has a selection option for one of the operating programs shown in the display or an operating program combination. In this context, furthermore, an operating method for a washing machine is known, which has an input unit which permits an individual compilation of a washing program by stepwise selection of individual setting variables.

A disadvantage of the laundry care device according to EP 0 898 003 A2 As well as the operating method, the adaptation of the operating programs is complicated and demands from the user, in order to be able to set an optimal combination of the relevant parameters in each case, in-depth knowledge of the various washing programs available.

In addition, laundry care devices are known which can display the expected program duration of an operating program setting. The disadvantage here is that the user must make various settings or combinations of operating programs to find an operating program, which has the program duration desired by him. He is often unable to identify the effects of his attitude on further results of the selected program. For example, the user is not informed that a shortening of the washing program may result in a deterioration of the cleaning result.

Furthermore, laundry care devices are known in which program options such as "fast", "already" or "ironing" are selected in combination with the operating program. In these laundry care devices, an operating program and each possible combination of operating programs are each assigned fixed operating values of the operating program parameters with which the best possible care result for the selected program setting can be achieved. This means that the user can not deviate from this predetermined optimum for a care result to be achieved, which is also referred to below as the final result, if, for example, another possible energy saving is more important to him than a very good care result.

The document WO-A-2008017910 belongs to the state of the art according to Art. 54 (3) EPC and discloses a laundry care device having a memory unit and at least one operating program with a plurality of operating program parameters selectably stored in the memory unit, a setting element for setting at least one setting variable, the setting variable being one with the execution of a selected one Operational program is to be achieved final result, and a control unit for automatically changing at least one operating program parameter in adaptation to the user-set set value.

The object of the present invention is the further development of the above-mentioned laundry care device as well as the operating method mentioned in the introduction in that the disadvantages of the prior art are at least partially eliminated.

The object is achieved by a laundry care device with the features of claim 1, which is equipped with a memory unit and stored in the memory unit operating program or subprogram with several operating program parameters, wherein the stored operating program and / or Teilbetriebsprogamm each assigned specific operating values of the operating parameters are. In addition, the laundry care device comprises at least one adjusting element for user-side setting of at least one setting variable and a control unit for automatically changing at least one operating program parameter in adaptation to the set user-set parameter. The laundry care appliance is characterized in that the setting variable is an end result to be achieved with the execution of a selected operating program or a partial operating program, whereby at least one specific operating value of the operating program parameters of the selected operating program or partial operating program can be changed automatically as a function of the adjusted, that is to be achieved, final result , In addition to the care result, the final result also includes the use of resources required for carrying out the care, for example, execution duration or

Operating program duration, water consumption, energy consumption or the consumption of cleaning and care products.

Likewise, in order to achieve the object, a method for operating a laundry care appliance after selecting an operating program with a plurality of operating program parameters having the features of claim 15 is provided. In such a method, the specific operating value of the operating parameters assigned to the selected operating program or partial operating program is adapted automatically and as a function of the adjusted end result which is to be achieved or carried out with the execution of the selected operating program or partial operating program. Thus, the final result to be achieved is a set value. If the operating program or the partial operating program has a plurality of operating program parameters, each having assigned specific operating values, then according to the invention at least one of the specific operating parameters is automatically adapted to the set final result.

The present invention thus provides a laundry care device and a method for its operation, which allow in an intuitive and thus uncomplicated manner, quickly, easily understandable and with little effort even the untrained user adapted to the individual ideas adaptation of the washing process.

The user can best estimate how heavily soiled his laundry is and how intensive the laundry treatment should be, or within what time he needs the laundry again. In addition, the user knows his own attitude towards ecological aspects of laundry washing the most accurate.

According to the invention, the user is provided with at least one adjusting element on a known laundry care device with which he can set one or more adjustment variables, such as the washing time, ie the length of the washing process, or the energy consumption, independently and individually for a selected operating program. In this case, an adjustment element for setting the adjustment variables or combinations thereof is preferably provided. On the one hand, the setting values can be directly related to the ones mentioned above Have operating program parameters, eg time (operating program duration). On the other hand, the setting variable in the sense of the present invention also includes more user-related variables which, in turn, indirectly affect the operating program parameters. These include, for example, the cleanliness of the laundry after a wash, briefly called the cleaning result, the degree of rinsing of the laundry, also called rinsing result, the residual moisture of the laundry after a final spin section, water consumption or energy consumption. This means that the user can specify the type and / or intensity of the treatment by setting a final result to be achieved. Of course, this list is not exhaustive and depends on the wishes of the user, which may change. For example, the desire to save energy is often in the foreground nowadays. The user does not have to cumbersomely choose from the offered operating programs and various subroutines himself an operating program that comes closest to his expectations, but he can select from a small number of possible operating programs an operating program and specify the final result to be achieved for this operating program. On the basis of this specification or the setting, the required specific operating values of the operating parameters are then automatically adapted.

The setting of these setting values affects at least one operating program parameter, often also several or all. If the user selects a "Delicates" operating program for the type of laundry, then the operating program should, for example, adjust the mechanical action, controlled by the drum movement, accordingly. If the user wishes to set the energy consumption of the selected operating program to a low value, it may be useful to use less water and wash at a lower temperature, which then leads to an extension of the operating program duration to achieve the same cleaning result as at a higher energy consumption. In addition, it would also be possible to vary the operating values of the operating program parameters that determine the mechanical action within predetermined and operating-program-dependent limits to increase the mechanical performance to improve cleaning performance to counteract the lengthening of the operating program duration.

Therefore, the laundry care device or the method is preferably further developed in that when setting an end result for a selected operating or partial operating program, which at the same time changed or deteriorates at least one other achievable end result of the selected operating or partial operating program, the specific operating value and / or at least another specific operating value of the operating program parameters are automatically set to operating values with which the further end result comes as close as possible to the final results achievable with the originally assigned specific operating values of the selected operating or partial operating program. The adjustment of the operating values preferably takes place within predefined limits, which depend on the selected operating or partial operating program.

The adjustment item for the user-side adjustment of the adjustment amount is designed to allow the setting of a plurality of values of a set value in a predetermined range.

In the laundry care appliance according to the invention, a storage unit is provided, in which, as in conventional laundry care appliances, operating programs or individual operating program parameters are stored, which can be selected by the user. Conveniently, these are standard programs to which the user is already accustomed, e.g. those which are designated according to the type of washing and the temperature (30 ° C cooking / colorful, 60 ° C cooking / colorful, 90 ° C cooking etc.). In contrast to conventional washing machines, where the user can only select these standard programs and possibly a few individual separate additional options, such as "short" (short washing time) or "light" (for lightly soiled laundry), the laundry care appliance according to the invention enables the user to to make a setting of certain setting values within a range. In addition to the operating programs, it is also possible to select partial operating programs, for example, pumps, centrifuging or soaking. A partial operating program is understood to mean a program which can be executed independently and preferably consists of a specific program part of an operating program.

The user may preferably select between multiple values within a range for each set size. This is particularly advantageous for a time delay, where the user can select the operating program duration, either stepless or in stages, eg in the time delay in 15-minute increments. For example, he can choose the program duration between 45 minutes and 3 hours.

The set value may also or additionally relate to the intensity. For example, a scale can be specified for the intensity at which the user can set a value. Other settings and their extremes can also be used.

The control unit adjusts the operating program according to the set parameter (s). The laundry care device according to the invention adjusts the operating program parameters of the operating program automatically, so that the washing program is ultimately adapted to the specifications by the user. For example, if the user desires low energy consumption, the other operating program parameters are usefully adapted within the framework of the selected operating program in order ultimately to achieve the lowest possible energy consumption. Thus, for example, the temperature of the wash liquor and the spin speed can be reduced for this purpose, in order to extend the wash duration, ie the residence time of the laundry in the wash liquor, instead. In the case of heavily soiled laundry, which has to be available relatively quickly, the user will on the contrary increase the setting value "Intensity" of the washing process and at the same time shorten the setting variable "Duration". For example, the washing temperature, the number of revolutions, the amount of washing liquor and, if an automatic metering device is present, the amount of detergent are automatically adjusted.

As a control unit for automatically changing at least one operating program parameter in adaptation to the setting variable (s), it is possible to use a microcontroller that can be used by default in laundry care appliances, to which appropriate operating software has been loaded. For this purpose fuzzy logic can be used.

If the operating program has a defined program sequence and a defined program duration, then in the laundry care device it is also preferable to have an arithmetic unit for calculating the change of the at least one Operating program parameters provided depending on the set value of the set size. This results in a calculation of the dependency of the individual operating program parameters on one another or the influence of a change on the operating program.

In the presence of a corresponding output or display unit, the user can be shown the respective change. The user is thus given the opportunity for an even more individual adaptation of the washing process to his needs or ideas. Preferably, a display for the reproduction of the operating program and / or the change of the operating parameters is provided.

In addition, a memory unit is preferably provided for storing the operating program parameters in a form combined into packets, wherein in each case at least one packet is assigned to a value of a setting variable. This storage unit may be either the above-mentioned storage unit for storing the standard programs, or another storage unit may be provided.

• "schnell" - - - - - "intensiv"
• "schnell" - - - - - "eco"

Various options are summarized as self-explanatory and user-oriented for the setting variables. Thus, easily understandable designations can be assigned to the boundary values of the adjustment variables, such as, for example

• "fast"
• "fast" - - - - - "eco"

In the embodiment "fast" - - - - - "intensive", the two extreme values "fast" and "intensive" are a combination of the setting variables operating program duration and cleaning intensity. Thus, advantageous options can be offered on both edge regions for the user. In this case, according to the invention, in this embodiment, with a change in the setting from fast towards intensive, the operating program parameters are changed towards stronger mechanics and possibly also greater energy consumption.

In the case of "fast" - - - - - "eco" when set to "eco" an extended operating program duration may be provided to save energy while simultaneously reducing the washing mechanism. The deliberately ambivalent term "eco" can be understood both as an abbreviation for an ecologically as well as an economically oriented washing process.

This means that a first extreme value for the first setting variable and a further extreme value for a further setting variable are combined and the setting of the further setting variable towards the further extreme value is changed by a change of the first setting variable from the first extreme value in the direction of the further extreme value ,

In order to avoid damage to the laundry items due to incorrect handling during the washing process, basic conditions are specified and determined by selecting a specific operating program. For example, it prevents the delicate laundry, such as e.g. Wool article is washed at too high rotational speeds or at inappropriate temperatures. Within the frame, which is predetermined by the selected operating program, then the user-side adjustment of the set sizes can be done. In order to select the appropriate operating program, a selector switch for selecting an operating program is preferably provided on the laundry care device. As a selector switch is conceivable here, for example, the use of a knob, a keyboard or a dial.

In order to make the operating area of the laundry care device as clear as possible, and taking into account the specifications by the product design, it is also advisable in this context, to integrate the setting element for user-side setting of the set size (s) in the selector switch.

Preferably, the adjustment is gradually or continuously adjustable. In this case, the adjusting element is designed in particular as a rotary selector, slide switch or controller, touch-sensitive switch or controller or as a rocker switch. Touch-sensitive switches or regulators are also referred to as touch-sensitive eyepieces, since the user can move them by simply moving his hand or even a finger over them Switch surface can perform a continuous adjustment of the appropriate setting size.

The choice of the appropriate adjustment is based both on the technical requirements that are placed on the adjustment, as well as design considerations. In addition, by selecting a particular, for example, large, easy to read and / or easy-to-use setting the accessibility of the device equipped in this way can be ensured. By selecting a particularly user-friendly adjustment element can also be underlined that with the user-side setting a set size a simple, automatic and particularly result-oriented feature of the laundry care device according to the invention has been created.

In a stepwise adjustment, it is conceivable that the change of the parameter takes place between respectively opposite extreme values in more or less high-resolution graduations. Thus, for example, an adjustment may be made in 5 to 20 stages, although both fewer and more stages may be provided, e.g. 3 to 5, 4 to 8, 10 to 25 or more.

Preferably, a display for reproducing the operating program and / or the change of the program sequence or the program duration depending on the change of the set sizes is provided on the laundry care device. The user can thus be shown the dependency of the operating program parameters on each other so that he can better estimate how the change of a parameter has an effect by adjusting the set value. In addition, a time display can be made via the preferably single or multi-line display, via which the program remaining running time can be displayed during operation of the device. The user is thus given the opportunity to select even better which operating option (eg, short washing time, particularly environmentally friendly washing process, more or less intensive cleaning, etc.) for him is currently in the foreground and is directly pointed to the effects of on / adjustment of a set size , In addition, the user can be shown on the display possible alternatives. However, it may also be pointed to the indirect consequences of a particular attitude (eg increased energy consumption).

In order to show the user the current position of the adjusting element, this advantageously has a display device for the adjustment of the adjusting element. This display device is preferably integrated in the adjustment or associated with the adjustment. The display device can be formed both optically and acoustically. One possibility for optical design provides for the display device to be configured as individual light-emitting elements (for example LEDs arranged in series), which illuminate one after the other with adjustment of the adjustment element, or as a row of individual light elements arranged above or below the adjustment element. It is also conceivable the formation of the adjustment as Touchslider with backlighting. The display device can also vary in color, for example, go from red to orange to green to give the user further feedback on the change in the operating program in response to the set by him setting.

A preferred embodiment of the method according to the invention is that the user-settable values of the setting values as well as the operating program parameters which can be changed automatically as a function of these are combined into packets. As a result, the operation of the laundry care device is further simplified and the number of possible variations limited to a reasonable level.

Preferably, a chemical, thermal, mechanical or temporal or other adjustment variable is set by the user. Moreover, it is considered to be particularly favorable if the user-side setting of the setting variable and the automatic change of at least one further operating program parameter take place stepwise or continuously. This can be done even finer gradation of the setting of the respective setting or, and it is user-side, a so-called "control loss feeling" avoided. Preferably, the user-side adjustment of the setting is carried out via an adjustment that can be configured as already explained above.

an embodiment of an adjustment with integrated display device.

Fig. 1 shows an adjustment 10 for placement on a laundry care device. The adjusting element 10 is used for the user-side adjustment of at least one setting variable in addition to a selectable operating program, whereby an automatic change of at least one operating program parameter takes place in adaptation to the set value of the setting variable. The adjusting element 10 is in the embodiment of Fig. 1 designed as a rocker switch 11. At the outer ends 12a, 12b, oppositely directed pointers 13 show the direction of the change in the setting size to one of the two possible operating modes 14 ("intensive", "fast") of the laundry-care appliance. In the embodiment of Fig. 1 Thus, the user is given the opportunity to perform the selected operating program either quickly, ie with a particularly short washing time, or intensively, ie with the highest possible cleaning effect. The operating program parameters are in this case already bundled into packages and cause a change in the operating program as a function of the adjustment of the adjusting element 10. As further combinations would be conceivable, for example, eco and fast. To illustrate the adjustment of the adjusting element 10 for the user, the adjusting element 10 is associated with a display device 15. The display device 15 is formed by arranged in series light elements 16 which indicate the selected position of the adjusting element 10 by lighting up. The light elements 16 are in the embodiment of the Fig. 1 by several LEDs that light up one after the other. In the embodiment of Fig. 1 the user has carried out a change of the operating program in the direction of a more intensive washing process, which, for example, offers for heavier laundry contamination. Although this lengthens the washing time, the laundry is cleaned more thoroughly.

The light elements 16 additionally provide the user with additional feedback on the change of the operating program by color change. It is also conceivable in this context to inform the user about the color change, for example from green to red, to a favorable or rather unfavorable change in the operating program. The optical display device 15 may also be associated with an audible indicator (not shown) which indicates an adjustment of the adjusting element 10, for example via a change in pitch, or indicates the program stop or a malfunction. It is also conceivable a voice output of the set size (s).

In Fig. 2 an adjusting element 10 is shown, which has a touch-sensitive controller 17, a so-called. Touchslider. At the outer ends 12a, 12b of the regulator 17, oppositely directed pointers 13 indicate the direction of the change of the setting variable to one of the two possible operating modes 14 of the laundry-care appliance. Am in the embodiment of Fig. 2 shown adjusting the adjustment sizes are already bundled into packages and give the user the ability to change the washing time or the washing intensity of the selected operating program gradually. An adjustment of the setting is made by the user moves a finger or the whole hand on the regulator surface 18. The controller is in the embodiment of Fig. 2 backlit. Depending on how far the user moves his finger or his hand over the control surface 18, the corresponding adjustment variables are changed. The change is illustrated by the illumination of a light element 16 integrated in the adjusting element 10 and indicates how far the operating program has been changed in the direction of a fast or an intensive operating mode 14.

The in Fig. 2 shown adjusting element 10 is also associated with a single-line display 20, via which the user the change in the program duration in response to the setting of the set size or the parameter packet is displayed as the time value 21. The user thus has the opportunity to influence the time value 21 directly via an adjustment of the adjustment variables. During the actual washing process, the remaining washing time is displayed 20 on the display. It is also conceivable that either a display of the remaining time, the total time or the already expired Wash duration and the user gets the opportunity to vary the display of the display 20 accordingly.
