BRIEF DESCRIPTION OF THE FIGURES

[0025] FIG. 1 is a block diagram of a system for the remote control of a household appliance; and

[0026] FIG. 2 is a flow chart of an exemplary method for the remote control of a household appliance.

DETAILED DESCRIPTION OF THE INVENTION

[0027] As described in the introduction, the present disclosure is concerned with the efficient, reliable, convenient and safe remote control of a household appliance. Referring now to the figures of the drawings in detail and first, particularly, to FIG. 1 thereof, there is seen an exemplary system 100 for the remote control of a household appliance 110. The system 100 can include several different household appliances 110, which are disposed at different points in a household, for example in the kitchen, in the bathroom, in a washroom, etc. A user 121 of one or several household appliances 110 can carry a remote control device 120, such as a smartphone, which enables the user 121 to control the one or several household appliances 110 remotely. To this end, the control device 120 can be embodied to send a control instruction for controlling a specific household appliance 110 through a (wireless) communication connection 103 to the specific household appliance 110.

[0028] In order to provide for a safe remote control of a household appliance 110, in particular for a safe operation, for example for a safe start, of a household appliance 110 by using a remote control device 120, it can be necessary for the user 121 to be located close to the remote-controlled household appliance 110 in such a way that the user 121 can monitor the operation of the household appliance 110 during the remote control. The system 100 can be embodied to determine the position of the user 121, in particular the position of the control device 120, relative to the remote-controlled household appliance 110. In this case, the position of the control device 120 can be determined by using an indoor positioning system of the household.

[0029] Some or all of the household appliances 110 can be embodied to serve as fixed anchor nodes in the indoor positioning system and therefore the household appliances 110 represent parts of the indoor positioning system. In particular, a household appliance 110 can have a position data unit 111, which is embodied to determine position data regarding the position of the control device 120 relative to the respective household appliance 110. The position data can be determined for example on the basis of a (wireless) communication connection 103 between the control device 120 and the respective household appliance 110, for example on the basis of a Bluetooth Low Energy (BTLE), on the basis of an Ultra-Wideband (UWB) and/or on the basis of an RFID (Radio Frequency ID) connection. The position data can indicate for example the signal strength and/or the distance or length of the communication connection 103 between the control device 120 and the respective household appliance 110.

[0030] The position data of different anchor nodes, in particular of different position data units 111, can be sent through a router 102 of the system 100 to a positioning unit 101 of the indoor positioning unit, which is configured to determine the position of the control device 120 relative to at least one household appliance 110 to be controlled remotely on the basis of the position data of several position data units 111. The determined position can be taken into consideration in the remote control of the household appliance 110.

[0031] The system 100 can include a control apparatus 104, which is configured to monitor the remote control of a household appliance 110 of the system 100. A control instruction 131 issued by the control device 120 of the user 121 can be forwarded through the router 102 to the control apparatus 104 (message 132). The control apparatus 104 can thereupon check the position, determined by the positioning unit 101 of the system 100, of the control device 120 relative to the household appliance 110 to be controlled remotely.

[0032] The remote control of the household appliance 110 can be enabled or prevented as a function of the position of the control device 120 determined by using the indoor positioning system. In particular, the control apparatus 104 can be embodied to forward the control instruction 131 to the household appliance 110 (messages 133, 134) if it is established on the basis of the determined position of the control device 120 that the user 121 is located in the immediate vicinity of the household appliance 110 (and can thus monitor the remote control of the household appliance 110). On the other hand, a forwarding of the control instruction 131 to the household appliance 110 can be prevented if it is established on the basis of the determined position of the control device 120 that the user 121 is not located in the immediate vicinity of the household appliance 110 (and thus cannot monitor the remote control of the household appliance 110).

[0033] If the control apparatus 104 is part of the household appliance 110, the control apparatus 104 can be embodied to enable or prevent the execution of the control instruction 131 (received at the household appliance 110) as a function of the position of the control device 120 determined by using the indoor positioning system.

[0034] In this way, a safe and convenient remote control of a household appliance 110 can be enabled, in particular without the user 121 having to confirm the remote control manually directly on the household appliance 110.

[0035] FIG. 2 shows a flow chart of an exemplary (possibly computer-implemented) method 200 for the remote control of a household appliance 110. The method 200 can be carried out by a control unit of a or the household appliance 110 and/or by a control apparatus 104 of a household (for example by a (smart home) server).

[0036] The method 200 includes receiving 201 a remote-control instruction 131 for the remote control of a household appliance 110 from a mobile control device 120 (such as a smartphone). The remote-control instruction 131 (sent from the control device 120) can be received over a wireless communication network at the control apparatus 104 and/or at the control unit of the household appliance 110.

[0037] The method 200 further includes determining 202 a position of the control device 120 relative to the household appliance 110 by using an indoor positioning system. The indoor positioning system can be embodied to determine the position of the control device 120 within the (entire) household in which the household appliance 110 to be controlled remotely is disposed. In this case, one or several household appliances 110 (such as a washing machine, a dishwasher, an oven, a refrigerator, a cooker or cooktop, a coffee machine, a freezer, etc.) can advantageously serve as fixed anchor nodes of the indoor positioning system.

[0038] Furthermore, the method 200 includes implementing or preventing 203 the remote-control instruction 131 as a function of the determined position of the control device 120. The implementation of the remote-control instruction 131 can take place for example if it is established on the basis of the position that the control device 120 is located in the immediate proximity of the household appliance 110. On the other hand, the implementation of the remote-control instruction 131 can be prevented. In this way, a safe remote control of a household appliance 110 can be enabled in an efficient, convenient and reliable manner.

[0039] The present invention is not restricted to the exemplary embodiments shown. In particular, it should be noted that the description and the figures are only intended to illustrate the principle of the proposed method and/or the proposed apparatus.
