Description

The present invention relates to a water-bearing household appliance.

In addition to good performance of the household appliance, the modern consumer or operator of household appliances also attaches importance to the fact that the household appliance uses resources sparingly. Of course, the washed laundry should continue to be hygienically clean.

In the DE 39 32 170 A1 describes a display device that stimulates the selection of energy-saving programs. Before a program starts, the operator is shown the expected energy consumption, with the option of selecting a program with lower energy consumption.

In the DE 697 28 496 T2 a household appliance is disclosed which describes a learning factor for an operator. The operator sets a washing program, the household appliance shows an expected consumption of resources on a display panel. After loading the household appliance with laundry and adding detergent, the operator starts the appliance. Now the device starts to calculate the actual need to be used based on the amount of laundry and the amount of detergent.

It is the object of the invention to enable an operator of a water-bearing household appliance to operate it intuitively.

This object is achieved by the features of claim 1 and claim 9, respectively. Advantageous embodiments are the subject of the dependent claims, the description and the drawings.

According to one aspect of the invention, the object according to the invention is achieved by a water-conducting household appliance. The water-bearing household appliance comprises at least one display unit, means for setting an operating program for the water-bearing household appliance, wherein changes to predetermined program parameters of the selected operating program of the water-bearing household appliance can be set with the means for setting. Furthermore, the water-bearing household appliance comprises a control unit for controlling the water-bearing household appliance, the control unit being coupled to the at least one display unit, the at least one display unit having at least one display field for displaying an expected resource consumption. The control unit is set up in such a way that an expected hygiene indicator is determined as a function of the program parameters set by the means for setting, the at least one display unit comprising at least one further display field that shows the expected hygiene indicator and the expected hygiene indicator can be determined depending on the expected consumption of resources.

An operator or a user is given a tool for a water-bearing household appliance that enables the operator to select an operating program that makes a hygiene factor visible through the expected hygiene indicator in at least one other display field and the operator by selecting one Operating program can change the hygiene factor or the expected hygiene indicator and adapt it to the respective needs. Furthermore, the operator is given a tool with which he can weigh up how high the hygiene indicator should be and whether it makes sense in the operator's eyes to use the resources required for it.

The hygiene indicator to be expected is intended to be a helpful display means for the operator in order to increase his well-being. On the one hand, this well-being is influenced by hygiene itself, since hygiene comprises the conditions and actions that serve to maintain health and counteract the spread of diseases. The hygiene indicator as a perceptible element visualizes the degree of change in terms of actual hygiene.

On the other hand, well-being is a sensation and therefore subjective, which is influenced by perception, e.g. visual stimuli. A hygiene indicator is understood to mean the representation of the change in the purity of the objects to be treated with regard to stains or soiling for the user.

The hygiene indicator is also to be understood as meaning that an object to be treated which was treated with a high hygiene indicator has a higher reduction in germs or allergens compared to a treated object which was treated with a lower hygiene indicator has experienced. The latter can be a useful aid for allergy sufferers, for example.

The expression 'a hygiene indicator to be expected' or the hygiene indicator 'are both expressions for a quantity that cannot be empirically measured and is only intended to indicate to the user whether something is, for example, high or low. In this case, the degree of hygiene should be made visible. In the following there is also no distinction between the two expressions 'an expected hygiene indicator' and a 'hygiene indicator'. Both are only used to illustrate the level of hygiene.

The at least one display field and the at least one further display field are both display fields which are provided in the at least one display unit. This means that the at least one display unit has many display fields, but all of which are arranged within the display unit. By way of example, the selection of the operating program is also displayed in a display field which, however, is also arranged in the display unit. It should be said that the at least one display unit has several display areas and a separate display field is provided for each symbol, value, information, setting variable.

The means for setting can comprise a first setting unit and / or a second setting unit and / or a third setting unit. However, the means for setting can also comprise any other number of setting units. Furthermore, the first and / or the second and / or the third setting unit can be designed differently. This is described in more detail below.

The hygiene indicator to be expected can preferably be displayed over a predetermined number of hygiene levels. As a result, the operator is well visualized how his selection of the operating program affects his end result or the hygiene indicator to be expected and / or the consumption of resources. Furthermore, the operator receives a simple view or a quick overview of the hygiene indicator to be expected and how it changes when the operating program is changed, for example.

The hygiene indicator to be expected can advantageously be displayed in the form of a column-shaped or bar-shaped display and / or an index consumption display and / or a ring scale and / or a round scale. The operator is thus given a visually good and simple display of the hygiene indicator to be expected, which the operator can easily and quickly overlook.

The water-carrying household appliance can be a washing machine, a dryer, a washer-dryer, a coffee machine and / or a dishwasher and / or the like. Furthermore, the water-bearing household appliance can also be a refrigerator and / or freezer or a refrigerator-freezer combination.

The water-bearing household appliance preferably comprises a storage unit which essentially stores a number of operating programs that have been carried out and is coupled to the control unit in such a way that the control unit sets a household appliance cleaning program between five operating processes and thirty operating processes, preferably between ten operating processes and twenty-five operating processes, preferably between five Operations and fifteen operations.

This makes it possible to increase hygiene, since after a certain number of operating programs of the household appliance has passed through, a cleaning program is set and the water-bearing household appliance is cleaned.

The first setting unit and / or the second setting unit advantageously comprises at least one touch-sensitive surface and / or at least one touch-sensitive display and / or at least one rotary selector and / or at least one push button and / or at least one rocker switch.

The at least one touch-sensitive surface and / or at least one touch-sensitive display can include, for example, a touchscreen, for example a capacitive or resistive touchscreen, and / or a touchpad and / or a TFT with a touch function and / or a multi-touch or the like.

It is therefore conceivable that the first setting unit is, for example, a rotary selector, the second setting unit, for example, a touchscreen, and the third setting unit has pushbuttons. However, any other embodiments of setting units and / or combinations of setting units are also conceivable.

This provides the operator with simple handling that corresponds to modern standards, which results in many different variants of setting units for the respective water-bearing household appliance.

In order to provide a user with a simple and modern display, the water-bearing household appliance furthermore preferably comprises a communication unit that communicates with an internal device and / or external device and wherein the communication unit is set up in such a way that functions of the means for setting and / or the at least one Display unit can be transferred to the internal device and / or external device. The internal device can be, for example, a touchscreen and the external device, for example, a smartphone or tablet.

The communication device is advantageously also set up in such a way that the communication device receives input commands from the internal device and / or external device and transmits the input commands to the control unit.

This gives the operator the opportunity to act playfully with input commands on the internal device and / or external device in order to select a program that appears to be optimal for the operator and to transmit this input command to the control unit by means of the communication device.

According to a second aspect of the invention, the object according to the invention is achieved by a method for a water-bearing household appliance, the method displaying with at least one display unit, setting an operating program of the water-bearing household appliance with means for setting. Furthermore, the method includes options for changing the predetermined program parameters of the selected operating program of the water-bearing household appliance with the means for setting and controlling the water-bearing household appliance by means of a control unit. The control unit is coupled in particular to the at least one display unit, the at least one display unit having at least one display field for displaying an expected resource consumption and the control unit controlling the water-bearing household appliance in such a way that a determination of an expected hygiene indicator is possible depending on the The first setting unit and / or the second setting unit set operating program and / or program parameters takes place, the expected hygiene indicator being displayed in at least one further display field of the at least one display unit and the expected hygiene indicator being determined as a function of the expected resource consumption .

As a result, an operator is shown an expected hygiene indicator, which occurs as a function of a selected operating and / or program parameter, whereby the operator can increase or decrease the expected hygiene indicator by selecting another operating and / or program parameter .

In order to provide an operator with a simple and modern display, the water-bearing household appliance preferably further comprises a communication unit that communicates with an internal device and / or external device, the communication unit being set up in such a way that functions of the means for setting and / or the at least one Display unit can be transferred to the internal device and / or external device.

The communication unit is advantageously also set up in such a way that the communication unit receives input commands from the internal and / or external device and the input commands are transmitted to the control unit.

This gives the operator the opportunity to act playfully with input commands on the internal device and / or external device in order to select a program that appears to be optimal for the operator and to transmit this input command to the control unit by means of the communication device.

The control unit 19th is particularly so with the memory unit 20th coupled that the control unit 19th after a certain number of operations of the water-bearing household appliance 1 sets a household appliance cleaning program. It may be that a household appliance cleaning program is set between five and thirty operating processes, preferably between ten and twenty-five operating processes, preferably between five and fifteen operating processes.

In 1 are the at least one display unit 13th and the first and second setting units 15th , 17th in an area that is the top of the housing 5 facing is shown. Furthermore, there are at least one display unit 13th and the first and second setting units 15th , 17th on a side wall 9 arranged. However, it is also conceivable that one or more units from the group of the at least one display unit 13th , the first and the second setting unit 15th , 17th on different side walls 9 and / or on the top of the housing 5 and / or on the underside of the housing 7th are arranged.

The at least one display unit 13th has at least one display field 21 to display an expected resource consumption. In the following, resource consumption is understood to mean that different resources are required when an operating program is selected. The resources are essentially energy, i.e. the electricity supply, and water. The various operating programs essentially have different resource requirements. This means that, for example, a first operating program has an average energy requirement and an average water requirement. A second operating program can, for example, have a higher energy requirement, but also an average water requirement. The values of average energy and / or water demand or the value of higher energy demand are only mentioned here by way of example in order to show that different operating programs can have different resource requirements. The exact values are of no further interest here.

In one display unit 13th but can also have several display fields 21 be integrated, so that there are no limits to the representation of symbols, values or the like. The display panel 21 can also include a touchpad so that the operator is given the option of making settings on the water-bearing household appliance 1 via the display panel 21 or the display unit 13th to do.

The at least one display unit 13th furthermore comprises at least one further display field 22nd . In the at least one other display field 22nd becomes an expected hygiene indicator 23 displayed. The one to be expected hygiene indicator 23 is intended to show the operator how his selection of the operating program affects hygiene. The expected hygiene indicator points to this 23 a predetermined number of hygiene levels.

It is also conceivable that the first adjustment unit 15th and the second setting unit 17th as well as the at least one display field 21 and the at least one further display field 22nd in the at least one display unit 13th are integrated. As a result, the water-bearing household appliance 1 only one element, the display unit 13th , on, the one on the front wall 10 of the water-bearing household appliance 1 is arranged.

As already mentioned above, the at least one display unit 13th have multiple display fields. It is understood here that every value, every symbol, every piece of information or the two setting units 15th , 17th are each shown in a display field, the display fields in the at least one display unit 13th are provided. However, it is also conceivable that individual components, such as the first and / or the second setting unit 15th , 17th can be designed or displayed in a further display unit, not shown here.

In 2 is exemplary as a water-bearing household appliance 101 a washing machine 102 shown. The following is the washing machine 102 described in more detail, with all of the newly mentioned features also being applied to the water-bearing household appliance 101 are due.

In the 2 illustrated washing machine 102 has how the water-bearing household appliance described above 101 in 1 , a housing 103 , a housing top 105 , a case bottom 107 and four side walls 109 on, with one of the four side walls 109 a front wall 110 is. Furthermore, the washing machine 102 at least one display unit 113 to display symbols and / or information. It also includes the washing machine 102 Means of adjustment 114 . The means of recruiting 114 include in the embodiment in 2 for example a first setting unit 115 and a second adjustment unit 117 .

But it is also conceivable that in addition to a first setting unit 115 and a second setting unit 117 there are also further setting units not shown here. It is also conceivable, however, that the means for setting 114 include only one universal setting unit with which all settings can be made.

The first setting unit 115 and / or the second setting unit 117 can include at least one touch-sensitive surface and / or at least one touch-sensitive display and / or at least one rotary selector and / or at least one push button and / or at least one rocker switch. But it is also conceivable that the first setting unit 115 and / or the second setting unit 117 is a combination of a touch-sensitive surface and, for example, a rotary selector. If the means for setting have, for example, only one setting unit, for example the universal setting unit, a touch-sensitive surface or display can be designed with an integrated rotary knob. However, other combinations are also conceivable.

The first setting unit 115 is used in particular to select an operating program. With the second setting unit 117 are changes to specified program parameters of the selected operating program of the washing machine 102 adjustable. The arrangement of the at least one display unit 113 , the at least one first setting unit 115 and the at least one second setting unit 117 can be chosen arbitrarily so that it can be adapted to the needs of the operator.

In contrast to the in 1 shown water-bearing household appliance 1 , includes the washing machine 102 in 2 an opening 125 by a door 127 is lockable. The door 127 is preferably pivotable on the washing machine 102 appropriate. Through the opening 125 items to be treated, such as laundry, can be put in the washing machine 102 introduced become. Furthermore, the washing machine 101 in 2 a bowl 129 on. The detergent bowl 129 can be filled manually by the operator and / or comprise an automatic dosing system.

The at least one first setting unit 115 and / or the at least one second setting unit 117 can also be designed as a display with an operating function and / or a touch-sensitive surface and / or a touch-sensitive display and / or as a switch and / or as a rotary knob. It is also conceivable that only one display unit 113 is formed in which the first and / or second setting unit 115 , 117 are integrated so that on the front wall 110 of the washing machine 102 essentially a display unit 113 is available. With such a display unit 113 all and / or almost all settings can be made and all symbols and information can be displayed at the same time. In this way, for example, a modern design and / or a user-friendly interface can be achieved. It is also conceivable that only one display unit 113 and means for adjusting.

In 3 is a further embodiment of a water-bearing household appliance 201 shown. The water-bearing household appliance 201 assigns an internal device 207 and / or external device 203 for communicating an operator or user with a water-bearing household appliance 201 on. The water-bearing household appliance 201 shows in particular the features of the in 1 water-bearing household appliance1 shown and / or the features of the in 2 shown washing machine 102 on. The internal device 207 and / or external device 203 can be a tablet, smartphone or the like. It is important that the internal device 207 and / or the external device 203 comprises a touch-sensitive surface and / or a touch-sensitive display for displaying and setting operating and / or program parameters.

The water-bearing household appliance 201 has a communication unit 205 on. The communication unit 205 is in connection with the external device 203 and communicates with the external device 203 . The communication unit 205 is set up in such a way that at least functions of the means for setting 14th . 114 and / or the at least one display unit 13th , 113 on the external device 203 are transferable. This allows a user interface of the water-bearing household appliance 201 and / or the washing machine 102 on the external device 203 being represented. But it is also conceivable that the external device 203 on the water-bearing household appliance 201 attachable or that an internal device 207 in and / or on the water-bearing household appliance 201 is trained. The internal device 207 can have similar properties as the external device 203 exhibit. The internal device 207 may have the means to recruit 14th , 114 and the at least one display unit 13th , 113 include.

Furthermore is the communication unit 205 set up in such a way that the communication unit 205 Input commands from the internal device 207 and / or external device 203 receives and the input commands to the control unit 19th , 119 transmitted. This gives the operator the opportunity to use the water-bearing household appliance 1 , 101 , 201 and / or the washing machine 102 to communicate without directly touching the water-bearing household appliance 1 , 101 , 201 and / or the washing machine 102 enter an input command.

The external device 203 can be a smartphone or a tablet, on which graphically the means for setting 14th , 114 and / or the at least one display unit 13th , 113 can be represented. The internal device 207 can be a processor. But it is also conceivable that the internal device 207 a smartphone or tablet is the one with the water-bearing household appliance 201 is detachably connected or permanently to the water-bearing household appliance 201 connected is.

In 4a to 4d each is a schematic representation of a display unit 413 of a water-bearing household appliance 401 shown. In the display unit 413 an exemplary embodiment is shown in each case, in which the hygiene indicator 23 , 123 , 423 changed. These exemplary embodiments are exemplified with a washing machine 102 shown. These exemplary embodiments are also applicable to other water-bearing household appliances 1 , 101 , 201 , 401 applicable.

In 4a instructs the display unit 413 a display panel 421 and another display field 422 on. As already mentioned above, the display unit 413 also have other display fields. In the display unit 413 three values are shown as an example that can be changed by selecting a program, here the energy field 405 and the field of water 407 , shown here, for example, in the display panel 421 , and the hygiene indicator 423 , shown here, for example, in the further display field 422 . These are the three values shown 405 , 407 , 423 to expected values, which means that no exact value is given, but only a possible estimate. An actually consumed value of the three values shown 405 , 407 , 423 can deviate to an expected value. This can mean, for example, that very cold water is flowing into the water-bearing household appliance 401 is introduced, more energy is required to be brought to a desired temperature than warmer water.

Furthermore, those in the 4a to 4d three values shown 405 , 407 , 423 in a columnar or bar-shaped representation or in a bar-box diagram. But it is also conceivable that the three values 405 , 407 , 423 in an index consumption display and / or a ring scale and / or a round scale or some other form of display.

The ones in the 4a to 4d The present exemplary embodiments are described using a bar-box diagram, the bar-box diagram having six boxes 409 per value. But there can also be more or fewer boxes 409 be present per value. Are zero or no boxes 409 at one of the three values 405 , 407 , 423 documented, this means a low energy and / or water consumption or a very low level of hygiene. However, all boxes are 409 assigned a value, such as the hygiene indicator 23 , 123 , 423 , this means that the laundry has a very high level of hygiene after running through the operating program. An example is in 4a the operating program is set to 40 degrees cotton.

In 4a the bar-box diagram shows that the expected energy consumption, the expected water consumption and the expected hygiene indicator 23 , 123 , 423 with three out of six boxes 409 lie. The bar-box diagram can now be changed by changing the operating program and / or the program parameters.

If the operator, as in 4b If the operating program is changed to 90 degrees cotton, certain values of the three values would also change 405 , 407 , 423 to change. Shown here as an example, the energy requirement would increase 405 on six out of six boxes 409 increase. The water consumption 407 would stay the same and the hygiene indicator 23 , 123 , 423 would focus on four out of six boxes 409 change. For the operator, this would mean that he would see an increase in the hygiene indicator in the event of an increased energy requirement 23 , 123 , 423 would achieve, which means that the laundry would become more hygienic.

If the operator were to select a first additional program as an example, as shown in FIG 4c is shown, the expected hygiene indicator would be 23 , 123 , 423 , compared to the value of the expected hygiene indicator 23 , 123 , 423 in 4a , on six out of six boxes 409 increase. The result is that the laundry would become more hygienic. However, this also immediately conveys to the operator that he has a higher energy 405 as well as water consumption 407 in comparison to the previously shown exemplary embodiments in FIG 4 a and 4b Has. For example, the operator can use the in 3 external device shown 203 Play through the various options and choose an operating program that appeals to the operator. By changing the program parameters, the operator can also change the three values 405 , 407 , 423 change. Depending on whether the operator uses less energy 405 and / or water consumption 407 have or have a high hygiene indicator 23 , 123 , 423 want to achieve, either another operating program and / or other program parameters can be selected.

The operator is given the opportunity to find out in a graphical or visual manner the degree of hygiene to be expected in comparison to a previous selection. Simply switching through operating programs is sufficient to recognize how the currently selected operating program differs from the previous operating program with regard to the degree of hygiene to be expected and the energy and water consumption to be expected. The operator can also quickly find out which is the best balance between the values of energy and water consumption on the one hand and hygiene on the other. Furthermore, the operator can weigh up between the individual operating programs and their program parameters which operating programs are useful for the hygiene goal.

In the illustrated embodiment in 4d , for example, the operating program 'Mix 30 degrees' is set. The values of expected energy and water consumption are neglected here and attention is paid to the expected hygiene indicator 23 , 123 , 423 placed. In the set operating program, there is an expected hygiene indicator 23 , 123 , 423 of two out of six boxes 409 specified. If the operator were to select a second additional program, the hygiene indicator to be expected could be 23 , 123 , 423 can be increased to four out of six boxes. The box 409 energy 405 and the box 409 water 407 would change accordingly.
