Description

A method for assisting an operator in setting parameters of a process of a household appliance and

household appliance

The invention relates to a method for assisting an operator in setting parameters of a process of a household appliance by making inputs to an operating device, wherein the inputs are received by a control device. Moreover, the invention relates to a household appliance, which is designed to carry out the method.

It is state of the art to display a power consumption of a household appliance by means of a display device. From the document DE 697 28 496 T2 it is known that the energy consumption of a washing machine can be predicted and displayed on a screen. During a washing process of the washing machine also the instantaneous power consumption or an integrated energy consumption of the washing machine is also displayed; At the completion of the washing process, the value for the total energy consumed by the washing machine during the washing process is displayed on the screen. In the article according to DE 44 46 883 A1 an operator when operating a washing machine is supported by that when selecting a

predetermined temperature level - for example 95 ⁰ C - a conspicuous signal is output. This signal alerts the operator that the washing process is energy consuming when the selected temperature level is applied.

From GB 2 416 852 A a measuring and indicating device is known with which a power consumption of a domestic appliance can be measured. The measuring and display device comprises a screen on which the current power consumption of the household appliance is displayed. In addition, the cost of the absorbed electrical energy can be displayed on the screen. The measuring and display device can interrupt an operation of the household appliance by decoupling the household appliance from a supply network when the cost of the Energy exceed a predetermined threshold. The measuring and display device can also be integrated in the household appliance, namely in a plug-in device of the

Household appliance. In the article according to document GB 2 416 852 A is the

Operator also given the opportunity to reset by means of an operating element, the display of the energy used or the display of the cost. Then the measuring and display device starts again, that of the household appliance

aufintegrieren recorded energy and calculate the cost of this energy.

It is an object of the invention to provide a solution how an operator can be assisted in setting parameters of a process of a household appliance better than in the prior art.

This object is achieved by a method with the features according to claim 1, as well as by a household appliance with the features according to

Claim 15 solved. Advantageous embodiments of the invention are the subject of the dependent claims.

In a method according to the invention, an operator is assisted in setting parameters of a process of a household appliance. The operator sets the parameters of the process by making inputs to an operating device of the household appliance. The inputs are controlled by a control device of

Home appliance received. In the method according to the invention, an input is received by the control device, via which at least one first parameter of the process is determined. For a plurality of possible, considering the input selected variants of the process, each in the first

Parameters and / or differ from each other in at least one other parameter, a value for each size is determined, the associated one

Consumption of resources. The control device outputs the respective value of the size for the entire plurality of possible variants, wherein the values are displayed by means of a display device of the household appliance.

Thus, when setting parameters of a process of the household appliance, the operator obtains information about the resource consumption by the household appliance, namely for a plurality of possible variants of the process - that is, for at least two variants, in particular for at least three variants. The operator can thus, taking into account the respective consumption of resources, select such a variant of the process which ensures the least consumption of resources.

Under a household appliance is in the present case understood a device that the

Housekeeping is used. This can be a large household appliance, like

For example, a washing machine, a tumble dryer, a dishwasher, a cooking appliance, a cooker hood, a refrigerator, a fridge-freezer or an air conditioner. But this can also be a small household appliance, such as a coffee machine or a food processor.

Thus, by the method according to the invention an operator is better supported in setting parameters of a process of the household appliance than in the prior art. In the prior art - in particular in the article according to DE 697 28 496 T2 - namely only a single variant of a washing process is proposed by the washing machine, for example, a certain temperature for the washing process is proposed. The energy consumption is calculated and displayed only for this single variant. In the prior art so can the

Operator can accept the single proposal or they can set the parameters of the washing process elsewhere, namely regardless of the proposal of the washing machine. In contrast, in the inventive method of

Resource consumption is determined for a plurality of variants of the process and displayed to the operator, even before the initiation of the process. Thus, the operator can select such a variant of the process, the predetermined

Meets criteria or is preferred by the operator.

The method according to the invention, for example, allows such a procedure in setting parameters of a process of a household appliance: The household appliance is a washing machine having a program selector, as well as a

Operating element for setting the temperature, a control element for setting the speed of the laundry drum and a control element for determining the time in which a washing process of the washing machine is to be terminated. An operator actuates the program selector and sets a specific sequence program of the washing process - for example, "Easy to clean." The sequence program of the washing process is set here a first parameter of the washing process, so the operator sets a first parameter of the washing process - the sequence program - fixed. A

Control device of the washing machine receives the input of the operator, via which the sequence program of the washing process is set. The controller now calculates for example, three variants of the washing process each have a value for consumption of electrical energy, water consumption and costs. The three variants of the washing process differ from each other, for example, in temperature. Thus, the controller calculates the respective

Resource consumption for three different temperature values for the specified sequence program ("Easy to clean") of the washing process .In addition or alternatively, the controller can also the respective resource consumption for others

Calculate and display sequence programs of the washing process. The operator can now set the parameters of the washing process, taking into account the respective resource consumption and start the washing process. The parameters in which the plurality of possible variants differ from one another may include, for example, a sequence program according to which the process is carried out. Then, the controller calculates the value for the resource consumption representing size for different process flow programs of the process. The respective values then become different for these

Sequence programs are displayed, and the operator can set the sequence program taking into account the displayed values. Assisting the operator in configuring the process may thus be to the effect that the

Bedienpeson the resource consumption for different flow programs is displayed, even if it has already set a specific flow program.

Additionally or alternatively, the parameters in which the plurality of possible variants differ from one another may include a temperature at which the process is carried out. Thus, the controller may determine the resource consumption for different temperature values, respectively, and the respective resource consumption values may be displayed to the operator. The

The operator is thus informed about how much the resource consumption - for example the power consumption - is influenced by the temperature. The operator can thus select such a temperature value, which on the one hand for an optimal result of the process and on the other hand for a low

Resource consumption ensures. The parameter "temperature" may be, for example, a temperature to which water in a washing machine or a

Dishwasher is heated, or act at a temperature of a process air in a tumble dryer.

Additionally or alternatively, the parameters in which the plurality of possible variants differ from one another may include a speed of movement of a component of the household appliance. For example, the parameters may include a speed of a laundry drum in a washing machine. Then, the controller calculates the respective resource consumption for different values of the speed, and the operator can reduce the speed

Define consideration of the respective resource consumption.

Additionally or alternatively, the parameters in which the plurality of possible variants differ from one another, can perform a

Additional program include. Such a parameter represents a binary parameter - the additional program is either performed or not. If the appliance is a washing machine, the parameters may include performing a pre-wash and / or performing an additional rinse. For example, in a dishwasher, the parameters may include performing an additional purge. The operator thus receives information about which influence on the resource consumption has the execution of an additional program. Under

Considering the consumption of resources, the operator can thus one

Run additional program or not.

For the plurality of possible variants of the process can each / a value for a consumption of electrical energy and / or a value for a

Water consumption and / or the costs of the process are determined and displayed as a size. For several variants of the process thus the operator receives the information about the respective consumption of electrical energy and / or water consumption and / or the cost. From this information, the

Operator select an optimal variant of the process for them or set the parameters of the process so that the lowest energy consumption and / or lowest water consumption and / or least cost of the process is / are achieved.

The control device determines the respective value for the quantity representing the consumption of resources, taking into account the input via which at least the first parameter of the process is determined. The control device thus takes into account the parameters initially set by the operator and / or the parameter value. If, for example, the input is used to set the temperature at which a

In the selection of the plurality of variants, the control device can take into account the temperature value and / or the parameter "temperature." It can be provided, for example, that the control device uses the resources for the set parameter value and for further values of the same parameter Additionally or alternatively, the

Control means to select such variants of the process and for each of these determine the resource consumption, which differ from each other in a further parameter. If, for example, the temperature is set via the input of the operator, then the control device can determine the resource consumption for a plurality of different sequence programs of the process at the specified time

Determine and display temperature value. In a preferred embodiment it is provided that at least one variant for the process is proposed by the control device, which corresponds to predetermined criteria with regard to the consumption of resources. Then, this suggestion can be displayed by means of the display device, for example by marking a variant of the process on a screen. In addition to the display of the

Resource consumption for different variants of the process can therefore also be proposed a concrete variant by the control device. The operator can thus be supported in setting parameters of the process to the effect that they do not have to select a variant of the process itself, but proposed such a variant that meets the predetermined criteria in terms of resource consumption.

Proposing the at least one variant may include a certain sequence program is proposed according to which the process is carried out and / or

a value for the temperature at which the process is carried out is proposed, and / or

a value for a speed of movement of a component of the

Domestic appliance, in particular a value for a rotational speed of a drum, for example a laundry drum, is proposed and / or

- the implementation of an additional program is proposed.

The latter may be, for example, performing a pre-wash on a washing machine and / or performing an additional rinse on a washing machine

Washing machine or a dishwasher. According to the predetermined criteria, the operator can be proposed an optimal variant for the process. Thus, the controller may suggest a variant of the process, namely one that satisfies the predetermined resource consumption criteria. For example, according to the predetermined criteria, such a variant can be proposed, which compared to the other variants:

- ensures the lowest consumption of electrical energy and / or

- ensures the lowest water consumption and / or

- ensures the lowest cost of the process.

The controller may thus read data from a memory containing information about these predetermined criteria. The control device can then subject the ascertained values for the consumption of resources as well as the data about the criteria to an analysis and, depending on this analysis, propose at least one variant of the process. The operator can thus get the cheapest for her variant of the process proposed and / or it can be proposed to her an energy-reduced and / or water consumption-reduced variant of the process.

The operator can also set himself at least one criterion, according to which a variant of the process is proposed by the control device. Then, the controller receives a further made by the operator Input via which this at least one criterion is determined. Thus, the operator is given the opportunity to decide for himself which aspects are most important to her when setting parameters of the process.

In a preferred embodiment, the operator is assisted in setting parameters of the process by providing information about the manner of generating resources available to the home appliance at a current time, as well as information about the manner of generating

Resources that are made available for the household appliance at least at a later date, are displayed by means of the display device. In particular, an information about the type of generation of electrical energy is displayed, which is currently available for the household appliance and will be made available at least at a later date. The type of generation of electrical energy is understood here as the manner in which the energy available in the electrical supply network was originally generated. Basically, between renewable energy and conventional

Differentiated energy. The renewable energy may, for example bioenergy, ie from vegetable oil, wood, biohydrogen and / or biogas produced energy and / or solar energy and / or energy generated from a wind power plant and / or energy generated from a hydroelectric power plant. The conventional energy can

Nuclear energy and / or energy produced from natural gas and / or produced from oil and / or energy generated from coal. By indicating the nature of the generation of resources that are currently available for the household appliance and are made available at least at a later date, the

Environmental friendliness of the household appliance compared to the prior art are significantly increased; because the operator can start the process of the household appliance at such a time or start automatically, to which "clean

Resources "are available.

It has been found to be particularly advantageous if at least one time for initiating the process is proposed by the control device, namely one which corresponds to predetermined criteria with regard to the manner of generating the resources. Then the proposal can be displayed by means of the display device. The operator does not have to decide at what time The process of the household appliance should be initiated, it can the proposal of

Follow the controller and start the process at the suggested time. It has proven to be particularly environmentally friendly, if after the

predetermined date such a time is proposed for a

predetermined type of generation of resources ensures. For example, such timing may be suggested for initiating the process at which the electrical energy supplied to the household appliance includes at least a predefined fraction of renewable energy. In particular, the predetermined criteria may include that the electrical energy comprises at least a predefined portion of energy from a hydroelectric plant and / or a solar plant and / or a wind power plant and / or a biomass power plant. Such a proportion may be, for example, in a range of values of 50% to 100%, in particular in a value range of 70% to 100%. In this embodiment, therefore, such energy for supplying the household appliance is preferred, which was produced in a "clean way" and environmentally friendly.

The operator can also set himself at least one criterion, according to which a time for the initiation of the process by the control device is proposed. The control device then receives a further input made by the operator via which this at least one criterion is determined. Thus, the operator is given the opportunity to decide for himself which aspects concerning the manner of generating the resources are most important to them.

Also during the process, information about the current resource consumption by the household appliance can be displayed by means of the display device. It can be during the process of each instantaneous value for the

Resource consumption reproducing size determined by the controller and displayed by the display device. In particular, the instantaneous value for the energy consumption can be determined, in particular measured, and displayed here. In particular, this is an energy that has been integrated since the beginning of the process or at a fixed point in time

Household appliance has been consumed, and / or to a current power consumption of the household appliance. The operator can then over the respective momentary

Resource consumption of the household appliance to be informed. It also makes sense possible, the current power consumption and / or the integrated

Display power consumption of individual components and / or functions of the household appliance, such as the current power consumption of an electric motor and / or heating. In this embodiment, a in the

Household appliance existing display device can be used; each one

Current resource consumption can be displayed alternately with information about a remaining time remaining to complete the process. Then, a switchover between the remaining time and the resource consumption takes place on an existing screen of the household appliance. In one embodiment, it is provided that, after completion of the process, a value for a variable representing a total resource consumption is given by the

Control device determined and displayed by the display device. For example, a value for a total energy consumption of the process and / or a value for a total water consumption and / or the actual total cost of the process may be displayed. The operator is thus informed after the process of the actual total resource consumption; This information may benefit the operator in setting parameters of another process of the household appliance. The value for the total resource consumption - that is, the value for the total absorbed electrical energy and / or the value for the whole

Water consumption and / or the total cost - can, in particular, assigned to information about the variant of the completed process, by the

Control device to be stored in a memory. Then, the information about each of the total resource consumption of different variants can be retrieved at any time by the operator and displayed by means of the display device. Thus, the operator is given the opportunity to evaluate the data relating to the resource consumption of different processes and also of different variants. For example, this might look like data about everyone

completed processes of the household appliance over a predetermined period of time can be retrieved, namely, for example in the form of graphics or tables. The invention also includes a household appliance, which is designed to carry out the method according to the invention or a preferred embodiment of the method. The preferred embodiments presented with reference to the method according to the invention and their advantages apply correspondingly to the household appliance according to the invention.

Further features of the invention will become apparent from the claims, the figures and the description of the figures. All features described above and

Feature combinations as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures are not only in the respectively indicated combination but also in others

Combinations or used alone.

The invention will now be explained in more detail with reference to individual preferred embodiments and with reference to the drawings. Show it:

Figure 1 is a schematic representation of a household appliance according to an embodiment of the invention. and

Fig. 2 shows an exemplary screen display, with which an operator at

Setting parameters of a process of the household appliance is supported.

A household appliance 1 shown schematically in FIG. 1 may be a household appliance or a household appliance. The household appliance 1 is a washing machine in the embodiment. The household appliance 1 comprises an operating device 2, by means of which an operator set various parameters of a washing process and the

Washing process can start by yourself. The operating device 2 may for example comprise a program selector for setting a sequence program, according to which the washing process is to be carried out. The operating device 2 may also include a control element for setting a temperature, an operating element for setting a rotational speed of a laundry drum of the household appliance 1, a

Control element for determining a time after which the washing process is to be completed, as well as at least one operating element, with which the

Performing an additional program of the household appliance 1 - as the particular Performing an additional rinse and / or a pre-wash - can be selected.

The household appliance 1 comprises a display device 3, which may comprise a screen 4. On the screen 4, the specified parameters of a

Washing process are displayed, such as the temperature, the speed, the specified sequence program and the time after which the washing process is to be completed.

With the operating device 2 and with the display device 3, a control device 5 is electrically coupled, with which the washing processes of the household appliance 1 are controlled according to the specified parameters. For this purpose, the control device 5 may include, for example, a microcontroller 6, as well as a memory 7. In the memory 7, data relating to the parameters of the washing processes may be stored. The microcontroller 6 can store data in the memory 7 and read from it. In the memory 7 program codes are stored, with the help of the microcontroller 6 the

Can carry out washing processes of the household appliance 1. The memory 7 also stores data containing information about possible temperature values, possible speed values, possible sequence programs and possible additional programs for the washing processes.

By means of the control device 5, a plurality of electrical consumers of the household appliance 1 can be controlled. For example, by means of

Control device 5, a drive motor 8 for the laundry drum, a heater 9, as well as a pump 10 are controlled. By appropriate control of the electrical consumers 8, 9, 10, the washing processes of the household appliance 1 can then be carried out in accordance with the specified parameters.

Hereinafter, a method according to an embodiment of the invention with reference to FIGS. 1 and 2 will be explained in more detail.

An operator makes a first input to the operator 2 by, for example, turning the program selector from a zero position to a "easy care" position. This input thus becomes a sequence program of a washing process established. In addition, the operator can also set the temperature and / or the rotational speed, namely by operating in each case a control element of the operating device 2. The microcontroller 6 receives all these inputs and stores corresponding data in the memory 7. After the microcontroller 6, the inputs from the operating device he supports the operator in setting the parameters of the washing process. For a variety of variants of the washing process - in

Embodiment for four variants - determines the microcontroller 6, the consumption of electrical energy, water consumption and the cost of the washing process when using the respective variant. The energy consumption, the water consumption and the costs can either be estimated or predicted by the microcontroller 6 for the majority of variants, or they can be read from the memory 7 for the respective variant. The variants for which the

Energy consumption, water consumption and costs are determined, each differing in at least one parameter, be it already set by the operator or not yet defined parameters.

The energy consumption, the water consumption and the costs are displayed for the plurality of variants by means of the display device 3, namely on the screen 4. FIG. 2 illustrates such an exemplary screen display. In the first column, a plurality of variants V are designated, namely in total four variants V1, V2, V3, V4. The first parameter P1 is the sequence program Pr. In this case, the first variant V1 is assigned a first sequence program Pr1, for example "cooking laundry", and the second variant V2 is likewise assigned the first sequence program Pr 1. The third variant V3 is assigned a second sequence program Pr2, for example "easy-care". The fourth variant V4 is also associated with the second sequence program Pr2.

In the third column, the temperature T is shown as the second parameter P2. The first and third variants V1, V3 are assigned a first temperature value T1. The second and the third variant V2, V4 is associated with a second temperature value T2. In the fourth column, the third parameter P3, for example, is the execution of an additional program ZP, for example the carrying out of an additional rinse or a prewash. In the first and the third variant V1, V3 is the Additional program ZP be performed. In the second and fourth variant V2, V4, the execution of the additional program ZP should be omitted.

For all four variants V1, V2, V3, V4 of the washing process by means of

Display device 3 of the respective energy consumption EV1, EV2, EV3, EV4, the respective water consumption WV1, WV2, WV3, WV4 and the respective costs K1, K2, K3, K4 displayed. So the operator will set the parameters of the

Washing process supported so that for four variants V1, V2, V3, V4 of the washing process, the associated resource consumption EV, WV, K displayed on the screen 4, and the operator can take into account the resource consumption EV, WV, K in setting the parameters , The variants V1, V2, V3, V4, for which the resource consumption EV, WV, K is determined and displayed, become less

Considering the first input of the operator selected and can be changed with each further input. For example, the operator may initially only the sequence program Pr and the

Set temperature T, and the microcontroller 6 may propose an alternative to each set by the operator parameter value. The variants V1, V2, V3, V4 then comprise different combinations of the parameter values initially determined by the operator and those selected by the microcontroller 6

proposed alternative parameter values. If the operator sets, for example, the temperature T of 90 ^° C., then the microcontroller 6 can suggest a temperature T of 60 ^° C. and / or 70 ^° C. If the operator specifies, for example, the sequence program "cooking wash", then the microcontroller 6 can suggest the sequence program "easy-care". For different combinations of the temperature values 60 ⁰ C and / or 70 ⁰ C and 90 ⁰ C and the sequence programs "easy care" and "cooking clothes" then the respective resource consumption EV, WV, K can be determined and displayed.

Thus, the energy consumption EV, the water consumption WV and the costs K are determined and displayed for a plurality of variants V in each case. It can also be provided that the microcontroller 6 proposes a specific variant V1, V2, V3 or V4 for the washing process. The microcontroller 6 may suggest such a variant V1, V2, V3, V4, the predetermined criteria with respect to

Resource consumption, ie the energy consumption EV and / or water consumption WV and / or the cost K corresponds. In particular, such a variant V1, V2, V3, V4 can be proposed which, compared with the other variants V1, V2, V3, V4, ensures the lowest energy consumption EV and / or the lowest water consumption WV and / or the lowest cost K of the washing process , The criterion according to which a variant V1, V2, V3, V4 is proposed can also be determined by the

Then the microcontroller 6 receives a further input, via which the criterion is determined, according to which a variant V1, V2, V3, V4 by the microcontroller. 6

should be proposed. This may for example be such that the operator can make a choice between three criteria, namely between the lowest energy consumption EV, the lowest water consumption WV or the lowest cost K. A proposed by the microcontroller 6 variant V1, V2, V3, V4 can then displayed on the screen 4, for example, the proposed variant V1, V2, V3 or V4 can be marked. In addition to the respective resource consumption EV, WV, K for the plurality of variants V1, V2, V3, V4 is on the screen 4 also information about the nature of

Generating the electrical energy that is available for the household appliance 1 at a current time, as well as information about the type of generation of electrical energy that is provided for the household appliance 1 at least at a later date, displayed. This information can be received by the microcontroller 6, for example, directly from an energy provider or also through the intermediary of an external device, in particular an electricity meter. For this purpose, the household appliance 1 may comprise a receiving device, via which data with information about the manner of generating the electrical energy are received. On the screen 4, therefore, respective information about the type of generation of electrical energy can be displayed, which is provided at different times for the household appliance 1. The operator can thus decide for himself at which time the washing process should be started or which composition of the energy for the washing process should be consumed.

Such an indication of the type of production of the electrical energy may, for example, look according to the following table:

As can be seen from the above table, the available proportion of renewable energy can be displayed for a plurality of times. The operator can thus decide for himself what proportion of renewable energy should be given for carrying out the washing process.

The microcontroller 6 can also propose a specific time for the initiation of the washing process itself, namely one which meets predetermined criteria with respect to the generation of the energy or with respect to the proportion of renewable energy. For example, the predetermined criteria may include giving a certain amount of renewable energy, say 60%, as shown in the table above. A criterion according to which a time for the initiation of the washing process by the microcontroller 6 is to be proposed can also be determined by the operator himself. This can be done, for example, with the aid of the operating device 2.

If the washing process is initiated, information about the current resource consumption by the household appliance 1 can be displayed on the screen 4 during the washing process. In particular, the respective current power consumption of the household appliance 1 is displayed on the screen 4, as well as the integrated energy consumption and the integrated costs, namely since the initiation of the washing process and / or with respect to a fixed time. This time can be set by the operator by the operator 2, and the integration of the energy and the cost can be reset at any time. On the screen 4, a current price for the electrical energy can be displayed; Information in this regard may also be received from an energy provider. After completion of the washing process on the screen 4 information about the total resource consumption of the washing process is displayed. In particular, the following information is displayed on the screen 4 after completion of the washing process:

an information about the total electrical energy generated during the

Washing process was consumed by the household appliance 1,

an information about the amount of water that was consumed during the washing process by the household appliance 1, and

- Information about the costs of the washing process. All of this information is also stored in the memory 7, namely assigned to an information about the selected variant V of the washing process or over the specified parameters of the washing process. The

The operator thus always has the opportunity to query data concerning this information with the aid of the operating device 2. Then, the microcontroller 6 reads the data from the memory 7 and generates a corresponding display on the screen. 4

There are now different procedures for the data. The data on the resource consumption of the completed washing process can be deleted from the memory 7 when initiating a further washing process. Alternatively, these data can be retained and, in addition to these data, further data with information about the resource consumption of further washing processes can be stored in the memory 7. For example, in the memory 7 each data with information about the respective resource consumption for a predetermined number of washing processes are stored, for example on the respective resource consumption of ten last washing processes - with every eleventh

Washing process will then overwrite the oldest record with the new data. Alternatively or additionally, in the memory 7 data about the respective

Resource consumption of washing processes are completed, which were completed within a predetermined time interval, for example, have been completed in the last 6 months. Then, the operator has the ability to retrieve all these data and display on the screen 4, namely in particular in the form of a table and / or a count. Such an ad might look something like this:

In the first column, the completed washing processes are consecutively numbered. Each completed washing process is assigned the respective closing date (second column), as well as the respective variant (third column), the respective one

Energy consumption (fourth column), the respective water consumption (fifth column) and the respective costs (sixth column). Such a display in the form of a table and / or a count can be generated by the operator by means of the operating device 2, for example by actuating a control element.

Overall, therefore, a household appliance 1 and a method are provided with which an operator is supported in setting parameters of a process of the household appliance 1. For a plurality of possible variants V of the process, which differ from each other in at least one parameter, the respective resource consumption EV, WV, K is determined and displayed. Taking into account the respective resource consumption EV, WV, K, the operator can select a most favorable variant for them. LIST OF REFERENCE NUMBERS
