Description

TECHNICAL FIELD

[0001] The present invention relates to a domestic appliance. In particular, the present invention relates to a wireless coupling of a domestic appliance with a mobile device. BACKGROUND

[0002] Domestic appliances comprise a graphic display on which a status of the appliance can be displayed. For example, a display on a refrigeration appliance can present the internal temperature, the fill level, the currently consumed energy or the operating mode. The operation of a domestic appliance is usually carried out by means of input means which are installed locally, for example switches or knobs. The input means can be implemented integrally with the output means, for example in the form of a touch-sensitive screen (touch screen).

[0003] The graphic display can be used to provide the user with additional functions which can go beyond the control of the domestic appliance. For example, a cooking recipe can be presented on the display. It has turned out, however, that the provision of additional functions, in the given example a collection of cooking recipes, can be laborious to implement. Such functions usually have to be updated regularly on a functional level and on a data level. Here, the service life of the domestic appliance can exceed the service life of the common platforms on which such functions can typically be provided by a multiple. Thus, the domestic appliance can already be far too old to reliably implement the additional functions in their current form before the end of its service life.

[0004] It can be cost-intensive to equip a domestic appliance with a processing device of superior performance; moreover, it is usually not known what specific requirements will be made on the provision of functions in the future, so that, despite this, the processing device can still be undersized in terms of what is required. SUMMARY

[0005] The task underlying the present invention is to provide an improved technique for controlling an output of a domestic appliance which is coupled with a mobile device. The invention solves this task by means of the subject matter of the independent claims. The dependent claims describe preferred embodiments.

[0006] According to a first aspect of the present invention, a domestic appliance is proposed, comprising: a communication device for wirelessly communicating; an output means; a device for determining a distance to a mobile device; a processing device, which is configured to wirelessly couple the mobile device with the domestic appliance and which is configured to provide an output of the mobile device on the output means depending on the determined distance.

[0007] The user can carry the mobile device with him and move freely in the area of the domestic appliance. The output of the mobile device on the domestic appliance can be provided in such a way that the perception of the output is matched to the distance of the user from the domestic appliance. The user can better perceive such an output and react to it if necessary. If such an output comprises information relating to a function of the domestic appliance for example, the user can better control such a function.

[0008] A particular advantage of the solution presented here is that mobile devices can be made available on domestic appliances. For example, it is not possible today to run an Android operating system on a domestic appliance because Google has not certified Android for this form factor. The use of a commercially available Android operating system on a domestic appliance can be achieved by the coupling of the mobile device to the domestic appliance presented here.

[0009] Such a device for determining the distance can comprise a dedicated sensor, for example an ultrasonic sensor, a radar sensor or a lidar sensor. In a preferred embodiment, such a device for determining the distance is implemented integrally with the communication device. For example, the distance between the mobile device and the domestic appliance can be determined on the basis of information already determined by the common communication device. Such information can arise or be determined purposefully, for example when communicating by means of WLAN or Bluetooth. Another conceivable device for determining the distance is based on UWB (ultra wide band, for example IEEE 802.15.3a).

[0010] The communication device can be configured to determine the distance on the basis of the strength or the interference-free nature of the wireless signal received from the mobile device. The strength of the received signal is also referred to as "received signal strength" (RSS) and can enable the determination of the distance if the strength of the signal emitted is known. The interference-free nature can be given as the signal-to-noise ratio (SNR). The determination of the interference-free nature can also take into account the error rate in the transmission of information between the domestic appliance and the mobile device.

[0011] In one embodiment, the distance between the appliances / devices is determined by means of the technology known as Beacon. Here, one of the appliances / devices emits a wireless signal containing a message. The message can include information about the strength of the emitted signal, the position of the transmitter, the identification of the transmitter or other recorded information. Thereby, a distance can be determined which can include a range of up to about 20 meters. The shorter the distance, the more accurately such a determination can be made. The receiver can better determine its own position depending on the distance from the Beacon. The accuracy of the determined position can be less than about 1 meter.

[0012] The output means can include a display device, wherein depending on the distance, the size, the detail richness or the color selection of the output is controlled. Here, the output provided can be matched to the capabilities of the display device, for example with respect to the display size, the orientation or the arrangement of individual information. If the display device is too small to display predetermined information in its entirety in the desired size, these information can be provided in the manner of a scrolling text or in a predetermined sequence one after the other.

[0013] The output means can include a controllable sound source, wherein depending on the distance, the volume of the output is controlled. For example, an audio data stream can be outputted in such a way that it is always perceived equally loud by the user, even if he changes his position in the room with the domestic appliance.

[0014] According to a second aspect of the present application, a mobile device comprises a communication device for wirelessly coupling with a domestic appliance, wherein the mobile device is configured to transmit an output to be provided to the domestic appliance.

[0015] The mobile device can be configured, inter alia, to perform the coupling with the domestic appliance depending on predetermined criteria. Such criteria can control, for example, which functions or applications implemented by the mobile device should be assigned to a predetermined domestic appliance or to a function implemented by the domestic appliance. Thus, the communication between predetermined communication partners from the domestic appliance and the mobile device can be more easily established. When the domestic appliance is within a predetermined distance, a function assigned to the domestic appliance can be automatically started on the mobile device. When the user carrying the mobile device approaches his stove, oven or other cooking device, a recipe application can be started on the mobile device.

[0016] Furthermore, such a criterion can control with which household appliance the mobile device is coupled. In particular, such a criterion can control that the mobile device is coupled only with a predetermined household appliance of the plurality of household appliances, for example a cooking zone having an integrated screen, such as a TFT or LCD screen. Alternatively, it can be coupled only with the household appliance that is closest, i.e. has the smallest distance to the mobile device. Such a determination can be performed on a predetermined group of household appliances, for example belonging to a predetermined household. According to a criterion it can also be provided that always the household appliance that is closest and has a certain capability is connected. For example, a criterion can provide that always the household appliance with a speaker that is closest should be coupled with the mobile device, so that a user walking through his residence with his mobile device running a music streaming service can also listen to the music on the household appliance with a speaker that is closest, respectively.

[0017] In an embodiment, the criterion can comprise information about in which case which application installed on the mobile device is to be started and / or in which case which application installed on the mobile device is to be output on an output means of the household appliance. For example, in the criterion it can be provided that when the mobile device is close to a cooking zone with a TFT screen, a recipe application should be started. Then, the recipe application is reflected on the TFT screen of the cooking zone although it is running on the mobile device as specified. If during cooking a call comes in, the criterion can provide that the call has a higher priority than the recipe application and thus the call is displayed on the TFT screen of the cooking zone with priority. In this way, the criterion can specify an interaction mode that is optimized for the user.

[0018] The mobile device can be provided for obtaining the criterion from a central unit. Here, wired or wireless communication means can be used. The central unit can control or manage aspects of the household appliances belonging to the user or belonging to a household.

[0019] The mobile device can be provided for receiving a wireless signal from the household appliance, determining a hint for its distance to the household appliance based on the received wireless signal; and transmitting the distance to the household appliance. By determining the distance from the mobile device side, also technologies available at the mobile device can be easily used. The household appliance or the control means can in particular be implemented as a beacon, the distance of which the mobile device can easily determine.

[0020] As already explained in detail above, the output mechanism of the domestic appliance can comprise a display device and / or a controllable sound source, wherein the provided output is matched to the capabilities of the display device (or to the distance) and / or the volume of the output can be controlled depending on the distance. It is provided in a particularly preferred embodiment that a parallel output on the mobile device is also adjusted depending on the output on the domestic appliance. This can mean, inter alia, that the size, the detail richness or the color selection of the output on the domestic appliance should also be seen in this form on the mobile device. That is, the mobile device can be provided for outputting the output on the domestic appliance also on the mobile device, wherein the output on the mobile device corresponds to the output on the domestic appliance, in particular in terms of size, detail richness, color selection and / or volume.

[0021] The system according to a further aspect of the present application comprises the domestic appliance as explained herein and the mobile device as explained herein. If the mobile device is provided for applying the criteria, the system can furthermore comprise a central unit for providing the criteria for the mobile device.

[0022] It is preferred that the mobile device is provided for determining its position based on the received wireless signal and transmitting it to the domestic appliance and that the domestic appliance is provided for determining the distance based on its position and the position of the mobile device. The mobile device can determine its position based on one or more sensors, for example by means of a satellite-aided radio navigation system or an inertial platform determination. Alternatively or additionally, the position can be achieved by a determination of the distance to one or more beacons, one of which the domestic appliance can comprise.

[0023] The method according to a further further aspect of the present application comprises the steps of determining a distance between a domestic appliance and a mobile device, wirelessly coupling the domestic appliance and the mobile device, transmitting an output of the mobile device to the domestic appliance and providing the output on the domestic appliance depending on the determined distance.

[0024] The distance mentioned above can be determined based on a wireless communication signal transmitted between the domestic appliance and the mobile device. Such a communication signal can comprise, inter alia, WLAN or Bluetooth (BT or BLE). Information transmitted by means of the communication signal can assist the determination of the distance.

[0025] The method can be implemented partially or completely by means of the control mechanism described herein, the domestic appliance described herein, the mobile device described herein or the mobile device described herein. The appliance / device implementing can comprise a programmable microcomputer or microcontroller and the method can be present in the form of a computer program product having program code means. The computer program product can also be stored on a computer-readable data carrier. Features or advantages of the domestic appliance, the mobile device or the system can be transferred to one another or to the method, or vice versa. BRIEF DESCRIPTION OF DRAWINGS

[0026] The application is explained more accurately below with reference to the drawings, in which:

[0027] Figure 1 A system having domestic appliances and mobile devices is shown; and

[0028] Figure 2 A method for controlling a domestic appliance is shown. DETAILED DESCRIPTION

[0029] Figure 1 A system 100 is shown, which has at least one domestic appliance 105, a mobile device 110 and optionally a central unit 112. An exemplary first domestic appliance 105 is shown exemplarily as an oven, a second domestic appliance as a refrigerator appliance; however, other appliances can also be used, for example a hob, an extractor hood or a blender. The domestic appliances 105 can in particular comprise kitchen appliances provided for operation in the kitchen of a household. These domestic appliances 105 are preferably located close to one another, for example in a common household or in a common room such as a kitchen.

[0030] The mobile device 110 preferably comprises a smartphone, a tablet or a smartwatch and is usually assigned to a predetermined user 115 who can carry the mobile device 110 with him. Predetermined functions can be provided on the mobile device 110, which can be triggered, inter alia, by an assigned program or application. Exemplary functions include the collection management of cooking recipes, the acoustic or text communication with another remote user or the implementation of a music output. To this end, the functions can provide an output to the user 115 by means of a local output mechanism on the mobile device 110, in particular in optical, acoustic or haptic form. Furthermore, the functions can analyze an input provided by the user 115 on a local input mechanism of the mobile device 110, which the user 115 provides, for example, manually. To this end, corresponding input and / or output mechanisms can be provided on the mobile device 110. The mobile device 110 can also be provided for analyzing further inputs or ambient parameters, which can be indirectly controlled by the user 115, such as position, acceleration or ambient brightness.

[0031] The mobile device 110 is usually provided for connecting to a wireless network, in particular a wide-area network such as the Internet. The mobile device 110 can also communicate with the central unit 112 via such a connection. To this end, the mobile device 110 can use, for example, WLAN or mobile radio. Furthermore, the mobile device 110 preferably comprises a wireless communication device 120, which is provided for establishing a wireless data connection with a local appliance device, for example with the domestic appliance 105.

[0032] The domestic appliance 105 comprises a control mechanism 125, which is preferably provided for controlling the functions of the domestic appliance 105. In one embodiment, the control mechanism 125 is provided for controlling a plurality of domestic appliances 105. The control mechanism 125 can also be implemented independently and not as part of the domestic appliance 105. In this case, the communication between the control mechanism 125 and the assigned domestic appliance 105 preferably takes place wirelessly, for example by means of the technology known as Home Connect. A plurality of control mechanisms 125 can also be provided in the household, which are each provided for controlling at least one domestic appliance 105. Here, these control mechanisms 125 can likewise be connected to one another in data technology.

[0033] The control mechanism 125 comprises a processing device 130, an input mechanism 135, an output mechanism 140 and a wireless communication device 145. The input mechanism 135 and the output mechanism 140 are in the present case exemplary implemented as a touch-sensitive screen, which is integrated in the present case exemplarily together. The input of the user 115 can be provided by touching areas of the input mechanism 135, wherein a visual cue to the input can be displayed in areas on the output mechanism 140. In this way, context-sensitive various inputs can be realized.

[0034] It is proposed according to the invention to perform a wireless coupling of the mobile device 110 with the domestic appliance 105. Then, the input of the user 115 on the input mechanism 135 of the domestic appliance 105 can be transmitted to the mobile device 110 and used there for controlling the function. In a corresponding way, the output of a function running on the mobile device 110 can be transmitted to the domestic appliance 105 and provided to the user 115 at the domestic appliance 105 by means of the output mechanism 140.

[0035] In one embodiment, the input and the output can be transmitted over a unique data connection. In another embodiment, a first data connection 150 can be provided for transmitting the input and a second data connection 155 can be provided for transmitting the output. Here, these data connections 150, 155 can be independent from each other and can use different protocols or technologies or they can be implemented as only one bidirectional connection.

[0036] Over the first data connection 150, the control device 125 can present itself as a user interface (UI) which is set up to detect and provide the input of the user 115. As a base protocol for the data connection 150, for example WLAN or Bluetooth can be used.

[0037] Over the second data connection 155, the control mechanism 125 can present itself as a UI streaming server with respect to the mobile device 110, i.e. as a device which accepts output data streams which can be directed to the user 115. As a base protocol, for example wireless display (Miracast) or wireless on-demand (AirPlay) can be used, which in turn can be established based on WLAN or Bluetooth.

[0038] The distance between the domestic appliance 105 and the mobile device 110 can be determined on the basis of one of these data connections 150, 155. In particular, the communication means 145 can be provided to estimate the distance and optionally also the direction of the mobile device 110 on the basis of the transmission parameters. In particular, the distance determination can be carried out using the signal strength, the signal-to-noise ratio or the error rate. If a plurality of antennas are available, the parameters corresponding to one another can be placed in context for the distance determination. This distance can be determined from the control mechanism 120 side or from the mobile device 110 side. The distance determined from the mobile device 110 side can be transmitted to the domestic appliance 105.

[0039] The mobile device 110 can also determine its own geographical position, for example on the basis of a determined satellite-assisted navigation system receiver, a determined inertial system receiver and / or a determined distance to one of these domestic appliances 105. To this end, the domestic appliance 105 can implement a beacon which provides its own position by means of a wireless signal. This technology can be easily used, in particular, on the basis of Bluetooth Low Energy (BTLE). The position of the mobile device 110 can then be determined on the basis of the transmitted position and the distance to the domestic appliance 105, which can be determined on the basis of the transmission parameters of the wireless signal. The determined position of the mobile device 110 can be transmitted to the domestic appliance 115, which can then determine the distance to the mobile device 110 on the basis of its own position.

[0040] Preferably, the processing means 130 are provided to mutually match the properties of the output mechanism 140 and the requirements of the received output of the mobile device 110. For example, the orientation of the available display area of the output mechanism 140 (portrait format or landscape format), the color capability, the graphic resolution or the size can be provided as properties to the mobile device 110. If the mobile device 110 is to provide an output which does not comply with these specifications, the processing means 130 can transform the output accordingly. Here, for example, the display size or resolution can be converted into one another, or the color palette can be reduced or distributed differently.

[0041] In some embodiments, the display area on the output device 140 can be dynamically used for the functions of the mobile device 110. In this case, the conversion can be carried out transparently, or the changed properties of the output mechanism 140 can be reported to the mobile device 110.

[0042] In a preferred embodiment, the mobile device can find out which capabilities the output means of the domestic appliance have. On the basis of this information and / or on the basis of the determined distance between the mobile device and the domestic appliance, the mobile device can scale the display accordingly and transmit it to the domestic appliance already in scaled form. In this way, the domestic appliance can be spared possibly laborious calculation operations.

[0043] In an embodiment, a memory means 160 is provided, which is connected to the processing device 130 of the control means 125. The memory means 160 is preferably provided to function as an intermediate storage (buffer) and to temporarily record information which cannot be transmitted to the mobile device 110 due to disturbances in the data connection 150. In particular, inputs detected on the input means 135 can be stored / buffered as an intermediate storage if necessary until the data connection 150 is re-established. Corresponding memory means can be provided from the mobile device 110 side to store outputs which cannot be transmitted to the domestic appliance 105 temporarily due to an interrupted data connection 155. The corresponding intermediate storage can be provided from the mobile device 110 side to store outputs which cannot be delivered until the data connection 155 is re-established.

[0044] It is preferred that the domestic appliance 105 comprises a first software component and the mobile device 110 comprises a second software component, which exchange input and / or output with each other. Here, these components can be established on the basis of the basic functions of the domestic appliance 105 (or the mobile device 110) respectively, which provide for the transmission over the data connections 150, 155. If one of these data connections 150, 155 should be temporarily interrupted, for example because the appliance 105, the device 110 are located outside an effective distance which can be bridged at maximum, because the antennas are disadvantageously oriented relative to each other or because an object, for example a person 115, is located in the Fresnel zone of the antennas, the information to be transmitted can be stored from the domestic appliance 105 side in the memory means 160 and / or from the mobile device 110 side in the corresponding memory means. If these data connections 150, 155 become available again within a predetermined time, for example approximately 10 seconds, approximately 5 seconds or approximately 2 seconds, the stored content can be transmitted and the memory means emptied. The software components do not have to be informed about the interrupted or disturbed data connection 150, 155. For example, it can be ensured from the domestic appliance 105 side that the continuous output of acoustic information provided from the mobile device is ensured. If one data connection 150, 155 is interrupted or disturbed for longer than the predetermined time, both data connections 150, 155 or only the data connection 150, 155 involved can be cleared. The reestablishment of one data connection 150, 155 can require a new authentication of one of the appliance 105, the device 110.

[0045] The output on the output means 140 of the domestic appliance 105 is preferably carried out in dependence on a determined distance from the mobile device. For example, when the user 115 carrying the mobile device 110 moves away from the domestic appliance 105 which is outputting, then the acoustic data stream can be outputted with an increased volume. The visual display can be enlarged with increasing distance.

[0046] The central unit 112 is configured to provide criteria to the domestic appliance 105 which can control two kinds of functions. The first possible function is to assign the domestic appliance 105 or a function running thereon to a function running on the mobile device 110. In other words, upon establishing a communication with a predetermined domestic appliance 105, an assigned application ("App") can be started on the mobile device 110. Which application can be determined based on the criteria and possible boundary conditions. The boundary conditions can relate to e.g. the functional state or capabilities of the domestic appliance 105. Personal preferences of the user 115 of the mobile device 110 can also be taken into account. For example, when the mobile device approaches a cooking device like an oven or a stove, a recipe application can be started on the mobile device. The criteria can be updated by the central unit 112 when necessary, e.g. because a new domestic appliance 105 is added to the same household, because a new user 115 belongs to the household or because the control mechanism 125 has been updated. The control mechanism 125 can be replaced or updated, e.g. by a software update.

[0047] The second possible function of the criteria is to select which of the plurality of domestic appliances 105 the mobile device 110 is coupled with. For example, it can be pre-given that a first application only communicates with that domestic appliance 105 which has the smallest distance to the mobile device 110. A second application can be limited to communicate with that domestic appliance 110 which comprises an acoustic output mechanism 140. Other specifications or combinations are possible.

[0048] The criteria can also determine which output is prioritized over which other output. If for example a plurality of functions or applications in the coupled mobile device 110 are active, it can be predetermined which output is prioritized over which other output. Individual messages or information can also have different priorities. For example, a notification about the end of a cooking time can be prioritized over the output of a video data stream. If a plurality of mobile devices 110 are coupled or can communicate with one domestic appliance 105, such a differentiation can also be made. In extension, priorities between the individual mobile devices 110 or their respectively assigned users 115 can also be taken into account.

[0049] Figure 2 A flow chart of a method 200 is shown. The method 200 can be implemented distributed over different components, in particular over the domestic appliance 105 and the mobile device 110. Exemplarily, steps which are typically assigned to the mobile device 110 are shown in the left area, steps which are typically assigned to the domestic appliance 105 are shown in the right area.

[0050] In step 205, the mobile device 110 can emit wireless signals, in particular electromagnetic signals, which can be received by the domestic appliance 105 in step 210. These steps can also be implemented in reverse, so that the domestic appliance 105 emits signals, which are received by the mobile device 110. The transmitting appliance 105, device 110 can emit the signals in a beaconing manner, so that the receiving device 110, appliance 105 can better determine its distance to the transmitter. The determination of the distance is also based on parameters of the physical or bit transmission between the mobile device 110 and the domestic appliance 105.

[0051] In step 215, the mobile device 110 can recognize the domestic appliance 105 and decide according to a criterion whether a communication should take place with it. The criterion can be predefined or downloaded from the external unit 112. If a communication is to take place, it can be determined according to the criterion which function or application is to be set for the communication with the current domestic appliance 105. The determined function or application can be started or it can be informed of the information received.

[0052] In step 220, the coupling to the domestic appliance 105 takes place from the mobile device 110 side, which performs the coupling in the corresponding step 225. The coupling can include the exchange of transmission parameters, the authentication or verification of the communication partners. Immediately after the coupling, information can preferably be exchanged in both directions simply.

[0053] In step 230, the mobile device 110 can determine its distance to the domestic appliance 105. This determination can be based in particular on parameters which form the basis of the communication, such as RSS or SNR. In an alternative embodiment, the mobile device 110 can also determine its own geographical position, wherein it can or can not have access to the parameters of the communication. In step 235, the determined distance and / or the determined position can be transmitted to the domestic appliance 105.

[0054] The domestic appliance 105 determines its distance to the mobile device 110 in step 240. For this purpose, it can base itself on the distance which was previously received from the mobile device 110 and which was determined from the mobile device 110 side. In a variant, the domestic appliance 105 can determine the distance with respect to its own position and the position of the mobile device 110, which it can have previously received from the mobile device 110. Alternatively, the domestic appliance 105 can determine the distance on the basis of parameters which form the basis of the communication, such as RSS or SNR, as explained above. In an alternative embodiment, a special sensor for determining the distance is provided. The sources of information can also be combined with one another in order to determine the distance.

[0055] In step 245, the mobile device 105 can transmit the output to the domestic appliance 105 via the established data connection 150, 155. The domestic appliance 105 can receive the output in step 250 and pre-process it according to the determined distance. For example, the size, frequency, color or orientation of a visual output can be determined according to the distance. The greater the distance, the more clearly or more prominently the output can be constituted. An acoustic output can be adjusted according to the distance in its volume or in the spectrum used. The pre-processed output can then be output by means of the output means 140.
