Description

[0001] The present invention relates to a method for operating a household appliance system which has at least one mobile operating device, at least one control device and at least one household appliance, wherein the household appliance comprises at least one transmitting / receiving device and at least one first sensor device for detecting at least one action, and wherein the mobile operating device comprises at least one communication device and at least one second sensor device for detecting at least one action. The at least one transmitting / receiving device and the at least one communication device are suitable and designed to communicate wirelessly with one another and / or with the at least one control device via at least one first communication channel, at least temporarily, wherein at least one property and / or one function of the household appliance can be set by means of the operating device.The present invention also relates to a household appliance which is suitable and designed to carry out such a method.

[0002] Household appliances typically have a large number of different operating and / or display elements in order to control the respective household appliance or to select and / or monitor device-specific functions and properties. However, these operating and / or display elements are often not permanently attached to the household appliance or included in the household appliance, but are provided by a mobile remote control by means of which the household appliance can be operated or controlled remotely. Such systems consisting of at least one household appliance and at least one remote control are used primarily when a particularly attractive visual design of the household appliance is to be achieved without operating elements and / or when the surface of the household appliance does not have enough space orProvides space for the control and / or display elements in order to arrange them clearly and to display device-specific functions and properties in a user-friendly manner.

[0003] From the publication JP 2018 194284 A, the operation of a hob using finger gestures is known, whereby the finger gestures are recorded on a projection surface by an optical sensor.

[0004] For example, the publication FR 3 098 677 A1 discloses the operation of a hob with a mobile control element.

[0005] From the publication CN 108 451 400 A a device for food processing is known which can be operated via gesture recognition.

[0006] From the publication CN 108 006 750 A, a hob is known which is operated via touch-free control concepts.

[0007] From the document JP 2019 027 635 A a hob with automatic pot detection is known, which has a vibration sensor.

[0008] From document US2020349860A1, an operating concept is known that uses a smartwatch.

[0009] Particularly in the case of household appliance systems with a household appliance that poses a certain risk to a user, such as a hob, cooking utensils and / or a stirring device or a mixer, it is necessary to check the legally required spatial proximity of the user and thus ensure that remote operation of the household appliance is excluded.

[0010] In known household appliance systems and methods for operating such household appliance systems, control commands often have to be confirmed using control elements arranged on and / or near the household appliance and / or multiple communication channels are used for communication between the remote control and the household appliance to increase safety and reliability. However, in these cases, the safety and reliability precautions, depending on their design, are too cumbersome and complex to be generally accepted by users. Therefore, with regard to the safety and practicality of such remote-controlled or remote-operated household appliances, it is desirable to further improve the known solutions and make operation more intuitive so that it can be learned and carried out quickly and easily, especially by new users.

[0011] It is therefore the object of the present invention to provide a method for operating a household appliance system that enables particularly safe and, in particular, intuitive and user-friendly operation of a household appliance system. This object is achieved by a method for operating a household appliance system having the features of claim 1 and by a household appliance system having the features of claim 10. Preferred developments of the invention are the subject of the dependent claims. Further advantages and features of the invention will become apparent from the exemplary embodiments.

[0012] The method according to the invention is suitable for operating a household appliance system comprising at least one mobile operating device, at least one control device and at least one household appliance. The household appliance comprises at least one transmitting / receiving device and at least one first sensor device for detecting at least one action, wherein the mobile operating device comprises at least one communication device and at least one second sensor device for detecting at least one action. The at least one transmitting / receiving device and the at least one communication device are suitable and designed to communicate wirelessly with one another and / or with the at least one control device via at least one first communication channel, at least one property and / or one function of the household appliance being adjustable by means of the operating device.The household appliance can be controlled at least temporarily by means of the operating device if the at least one operating device is arranged at a predetermined distance from the at least one household appliance and if at least the first and the second sensor device each detect at least one predetermined action.

[0013] According to the invention, the first and / or second sensor device comprises at least one acceleration sensor and / or a motion sensor and / or a vibration sensor, which detects at least one predetermined action. In this case, a movement originating from the user is detected, in particular a movement of the mobile operating device with the user.

[0014] Based on the detection of the user's movement in the form of a predetermined action, such as touching the household appliance, which is in particular a stroke and / or a swipe and / or a knock and / or a tap, a correlation can be established between the mobile operating device and the household appliance. This is possible because the predetermined action is detected equally by the sensor device of the household appliance and by the sensor device of the mobile operating device. For example, knocking on an oven door or moving a cooking vessel is detected by separate sensors of separate devices at the same time and therefore enables validation of the proximity of both devices. In this way, an operating input or a process confirmation can then be manually transmitted to or confirmed by the household appliance.

[0015] Alternatively, based on the detection of the user's movement in the form of a predetermined action, a directed approach or leading movement of the user can be used to enable this validation. Using the sensor device of the mobile operating device moved by the user, a spatial movement is detected, from which a movement vector can be derived. If this movement vector is aligned with the location of the household appliance, it becomes clear to which household appliance an operating input or process confirmation is being manually transmitted or for which it is being confirmed.

[0016] Preferably, the at least one operating device is arranged at a predetermined distance from the at least one household appliance and at least the first and the second sensor device each detect at least one predetermined action, whereupon an at least temporary release of the household appliance for operation or control and an at least temporary release of the operating device for control or operation takes place, so that the household appliance can be operated or controlled by means of the operating device.

Depending on the task and design, an automatic temporary assignment between the household appliance 4 and the operating device 2 can also take place using only one assignment signature.

[0103] In the exemplary embodiment shown here, the association between the household appliance 4 and the control device 2 is maintained for a period of, for example, 5 minutes. Subsequently, the association between the household appliance 4 and the control device 2 is canceled or deleted, and a new association between the household appliance 4 and the control device 2 is established by transmitting a new association signature.

[0104] In the exemplary embodiment shown here, the communication device 7 sends, in addition to the assignment signature, a signal with at least one connection signature to the household appliance 4, by means of which the household appliance is automatically integrated into a second communication channel 11, so that the transmitting / receiving device 5 and the communication device 7 can communicate via the second communication channel 11 in addition to the first communication channel 9.

[0105] Here, the second communication channel 11 is provided by a WLAN connection, which has a higher signal transmission rate than the first communication channel 9 provided by a Bluetooth connection. Depending on the task and design, the second communication channel 11 can also be provided by a Bluetooth, NFC, IR, and / or an acoustic communication connection.

[0106] The operating device 2 sends a control signal to the control device 3 to control the household appliance 4. The control device 3 verifies the control signal using the assignment signatures transmitted to the control device 3 from the communication device 7 and the transmitting / receiving device 5.
