In response to receiving the remote control commands, the server 220 is operable to send data for remotely controlling the household appliance 100 to the wireless communications unit 205 of the household appliance 100. This allows a user to remotely control the household appliance 100 via the user equipment 230. In embodiments, the user equipment 230 is configured to communicate with the household appliance 100 directly, additionally or alternatively to communicating via the server 220. For example, the user equipment 230 may be configured to communicate with the household appliance 100 via Bluetooth. The household appliance 100 is operable to be remotely controlled when a remote control mode of the household appliance 100 has been enabled. In embodiments, the household appliance 100 is configured to send a message via the wireless communications network 210 to the server 220, the message indicating that the remote control mode of the household appliance 100 has been enabled. Such a message may be sent in response to the remote control mode being enabled, and/or may be sent to the server 220 periodically. In response to receiving the message, the server 220 is configured to permit remote control data to be sent to the household appliance 100. In embodiments, the server 220 is configured to send a message to the user equipment 230, the message indicating that the remote control mode of the household appliance 100 has been enabled.

In embodiments, the server 220 is configured to send to the user equipment 230 data indicating a list of supported remote control commands for the household appliance 100. The server 220 may send the data indicating the list of supported remote control commands to the user equipment 230 when the user equipment 230 is initially configured to remotely control the household appliance 100, e.g. when an application for remotely controlling the household appliance 100 is installed and/or configured on the user equipment 230. Additionally or alternatively, the server 220 may send the data indicating the list of supported remote control commands to the user equipment 230 when an application for remotely controlling the household appliance 100 is updated or every time the remote control mode of the household appliance 100 is enabled. The data indicating the list of supported remote control commands is based on one or more characteristics of the household appliance 100. Such characteristics may include, for example, a make, model, type, and/or capability of the household appliance 100. As such, the remote control commands that are supported for the household appliance 100 depend upon the characteristics of the household appliance 100, and the server 220 is configured to inform the user equipment 230 which remote control commands are supported. The list of supported remote control commands may be displayed on a display screen of the user equipment 230, according to embodiments. Remote control commands which are not supported for the household appliance 100 may not be displayed, or may be ‘greyed out’, for example. In embodiments, user input at the user equipment 230 comprises selecting one or more remote control commands from the list of supported remote control commands. Accordingly, remote control of the household appliance 100 may be performed in a user- friendly, efficient and flexible manner. In embodiments, the household appliance 100 is operable to be remotely monitored when a remote monitoring mode of the household appliance 100 has been enabled. In the remote monitoring mode, the wireless communications unit 205 is operable to send messages via the wireless communications network to the server 220 for remote monitoring of the household appliance 100. Such messages indicate operational information of the household appliance 100. The operational information may include, for example, the status of the household appliance 100, one or more operating parameters of the household appliance 100, an operating program of the household appliance 100, the value of a timer associated with the household appliance 100, etc. In response to receiving such messages, the server 220 is configured to send data indicative of the operational information of the household appliance 100 to the user equipment 230. The user equipment 230 may then generate output data, e.g. audio-visual data, based on the operational information. For example, the user equipment 230 may display the operational information on a visual display (or ‘graphical display’) of the user equipment 230. This allows the user of the user equipment 230 to remotely monitor the household appliance 100. In alternative embodiments, the server 220 does not send data indicative of the operational information of the household appliance 100 to the user equipment 230. For example, the server 220 may be configured to store and/or analyse such information without sending the information to the user equipment 230. In some cases, in the remote monitoring mode (unlike the remote control mode) the household appliance 100 is not operable to be remotely controlled. In alternative embodiments, the household appliance 100 is not operable in a remote monitoring mode, as opposed to the remote control mode, and/or is not operable to be remotely monitored.

In embodiments, the household appliance 100 is operable in a remote access mode, in which remote control and/or remote monitoring of the household appliance 100 is permitted. That is, the remote access mode may include the functions and/or permissions of the remote control mode, the remote monitoring mode, or both.

Figure 4 shows a method 400 of operating a household appliance, according to embodiments. The method 400 may be used to operate the household appliance 100 described above with reference to Figures 1 to 3. The household appliance 100 comprises a wireless communications unit 205. The wireless communications unit 205 is switchable between an activated state, in which the wireless communications unit 205 is operable to transmit and receive data via a wireless communications network, and a de-activated state. The household appliance 100 is operable, when a remote control mode is enabled, to be remotely controlled based on remote control data received via the wireless communications unit 205. In embodiments, the method 400 is performed at least in part by the controller 310. That is, the controller 310 is configured to perform at least some of the steps of the method 400.

In step 410, when the wireless communications unit 205 is in the de-activated state, a signal is received. The signal is generated in response to performance of a predetermined single user action. The predetermined single user action is performed by a user directly on the household appliance 100 and is associated with a first operating activity of the household appliance 100.

In step 420, in response to receiving the signal, the household appliance 100 is controlled to perform a second, different operating activity of the household appliance 100. Performing the second operating activity comprises switching the wireless communications unit 205 from the de-activated state to the activated state, thereby enabling the household appliance 300 to transmit and receive data via the wireless communications network. As such, a user action that is associated with a first operating activity of the household appliance 100 causes a second, different operating activity, involving switching the wireless communications unit 205 from the de-activated state to the activated state, to be performed. The single user action is thus associated with both the first and the second operating activity of the household appliance 100. In other words, the wireless communications unit 205 is activated in response to a single user action, performed on the household appliance 100, that is associated with an operating activity that is different from the activity of activating the wireless communications unit 205. This provides an improved user experience, e.g. in terms of efficiency, simplicity and/or comfort, compared to a case in which a separate, dedicated user action is required to activate the wireless communications unit 205. In particular, the number of interactions between the user and the household appliance 100 is reduced compared to known methods. The relative complexity for the user of operating the household appliance 100 may therefore be reduced. Moreover, by reducing the number of interactions between the user and the household appliance 100, the amount of processing performed by the household appliance 100 (in particular by the controller 310 and/or the user interface 150) may be reduced, thereby improving the efficiency of the household appliance 100.

In embodiments, the method 400 comprises controlling the household appliance 100 to perform the first operating activity in response to receiving the signal. As such, both the first operating activity and the second operating activity may be performed in response to a predetermined single user action. This is more convenient, user-friendly and/or efficient compared to a case in which performing the two operating activities require two separate user actions.

In embodiments, performing the first operating activity of the household appliance 100 comprises enabling the remote control mode of the household appliance 100. Therefore, the remote control mode may be enabled and the wireless communications unit 205 may be activated with a single user action. This provides an improved user experience, e.g. in terms of efficiency, compared to a case in which separate user actions are required to enable the remote control mode and to activate the wireless communications unit 205. Moreover, this may reduce an amount of processing performed by the household appliance 100 in order to perform the first and second operating activities, compared to a case in which separate user interactions are required. In embodiments, the predetermined single user action comprises a user action to enable the remote control mode. For example, the predetermined single user action may comprise the actuation of a button that is associated with turning on the remote control mode. Known household appliances may require a user to activate a wireless communications unit (e.g. to turn on Wi-Fi) and then separately enable a remote control mode. For example, a user interacting with a hierarchical user interface of a known appliance may be required to perform the following navigational operations to activate Wi-Fi: menu -> settings -> connections -> Wi-Fi on/off. The user may then be required to separately perform the following navigational operations to enable the remote control mode: menu -> settings -> remote control on/off. Further, it may not be possible on known household appliances to enable the remote control mode unless Wi-Fi has already been turned on. For example, a remote control option may not be available in the menus of the user interface, or a “toggle” may be greyed out, if WiFi has not already been turned on. In contrast with such known household appliances, the appliances and methods disclosed herein enable both Wi-Fi to be turned on and the remote control mode to be enabled, in response to a single user action, thereby providing a more efficient user experience.

In embodiments, the predetermined single user action comprises actuating a multifunction user input part of a user interface of the household appliance 100, e.g. the multifunction user input part 325 described with reference to Figure 3 above. For example, the predetermined single user action may comprise pressing a multi-function button. In embodiments, the method 400 comprises controlling the household appliance 100 to perform the first operating activity (in addition to the second operating activity) in response to actuation of the multi-function user input part 325. The multi-function user input part 325 thus has multiple functions, one of which is to activate the wireless communications unit 205. The multiple functions are performed in response to a single actuation of the multi-function user input part 325. This is more efficient and/or user-friendly compared to a case in which such a multi-function user input part of a user interface is not used to activate the wireless communications unit 205.

In embodiments, the household appliance 100 comprises a dedicated user input element (e.g. a button) actuatable to cause the wireless communications unit 205 to be switched from the activated state to the de-activated state and/or from the de-activated state to the activated state. That is, the sole function of the dedicated user input element is to activate or de-activate the wireless communications unit 205, e.g. to turn Wi-Fi on or off. In embodiments, the dedicated user input element comprises a soft-key button used in accordance with a hierarchical menu structure. For example, the wireless communications unit 205 may be activated by performing the following navigational operations: menu -> settings -> connections -> Wi-Fi on/off. The final operation, e.g. “Wi-Fi on/off”, may be considered actuation of a dedicated user input element, because this operation is not a multi-function operation, but is instead a single-function operation. The method 400 comprises switching the wireless communications unit 205 from the de-activated state to the activated state without the dedicated user input element being actuated. In other words, the method 400 involves activating the wireless communications unit 205 independently of the dedicated user input element. As such, the predetermined single user action does not involve actuating the dedicated user input element. Therefore, in some cases, the wireless communications unit 205 of the household appliance 100 may be activated in two different ways: first, the wireless communications unit 205 may be activated by actuating the dedicated user input element; and second, the wireless communications unit 205 may be activated by performing the predetermined single user action. This provides the household appliance 100 with increased flexibility and/or functionality.

In embodiments, the household appliance 100 comprises a sensor, such as the sensor 350 described with reference to Figure 3 above. The sensor 350 is configured to sense performance of the predetermined single user action on the household appliance 100, and in response to sensing performance of the predetermined single user action, output the signal that is received in step 410. As such, the performing of the predetermined single user action can be detected automatically, through use of the sensor. In embodiments, the sensor 350 comprises a door sensor configured to sense opening and/or closing of the door 120 of the household appliance.

The predetermined single user action may comprise any single user action that can be carried out directly on the household appliance 100 and detected by a sensor. The predetermined single user action may be selected from a predefined set of single user actions. Performance of any one of the predefined set of single user actions may cause the wireless communications unit 205 to be activated.

In embodiments, the predetermined single user action comprises opening or closing a door 120 of the household appliance. Such an action may be sensed by a door sensor. In alternative embodiments, for example when the appliance is a cooker comprising a heating element 330, the predetermined single user action comprises controlling a heating element 330 of the household appliance 100. In embodiments, the predetermined single user action comprises setting a timer 340 on the household appliance 100. Opening and closing the door 120, controlling the heating element 330, and setting the timer 340, are each examples of single user actions which are associated with a first operating activity of the household appliance 100, e.g. using the household appliance 100 to cook food. The first operating activity may comprise a primary operating activity, or primary function, of the household appliance 100. In other types of appliances, the single user action may be associated with other types of primary operating activities. For example, in embodiments where the household appliance 100 comprises an air conditioner unit including an ionizer, the predetermined single user action may comprise activating or de-activating the ionizer.

Additionally or alternatively, as discussed above, the predetermined single user action may comprise actuating a multi-function user input part 325 of the user interface 150 of the household appliance 100. For example, the predetermined single user action may comprise actuating a user input part of the user interface 150 to enable the remote control mode of the household appliance 100. In other examples, the predetermined single user action comprises actuating a user input part of the user interface 150 to enable a remote monitoring mode of the household appliance 100, to set a timer of the household appliance 100, to set or adjust an operating program of the household appliance 100, etc. Actuating the multi-function user input part 325 of the user interface 150 may be sensed by a sensor, e.g. a capacitive touchscreen sensor. In embodiments, the predetermined single user action comprises controlling the household appliance 100 to perform a household task. Such a task may comprise a cooking task, a cleaning task, a food preparation task, etc. In embodiments, the predetermined single user action comprises changing an operating mode of the household appliance 100. In alternative embodiments, the predetermined user action comprises selecting an operating program from a set of operating programs useable by the household appliance 100 to perform a task.

In embodiments, the predetermined single user action is associated with the first operating activity but does not cause the first operating activity to be performed. For example, where the household appliance 100 comprises an oven, the predetermined single user action may comprise opening the oven door 120. Such a user action is associated with the operating activity of cooking food, but does not itself cause food to be cooked. In any case, however, the predetermined single user action is associated with an operating activity of the household appliance 100 which is different from the operating activity of activating the wireless communications unit 205.

In embodiments, the predetermined single user action comprises a user action to enable a remote monitoring mode of the household appliance 100. The remote monitoring mode may be enabled by actuation of an associated button on a user interface, for example. Additionally or alternatively, the remote monitoring mode may be enabled in response to a user action such as opening or closing a door of the household appliance 100, setting a timer on the household appliance 100, etc. When the household appliance 100 is operating in the remote monitoring mode, the wireless communications unit 205 is operable to send messages via the wireless communications network to a server for remote monitoring of the household appliance 100. As such, the remote monitoring mode may be enabled without the user having to separately activate the wireless communications unit 205 that is to be used for remote monitoring of the household appliance 100.

In embodiments, the predetermined single user action is performed when the household appliance 100 is in a standby state. The predetermined single user action may cause the household appliance 100 to change from the standby state to an ‘awake’ state. In some cases, the household appliance 100 is configured to remain in the standby state when the predetermined single user action is performed.

In embodiments, the predetermined single user action is performed when the household appliance 100 is in the remote monitoring mode. For example, if the predetermined single user action comprises opening the door 120 of the appliance 100, the wireless communications unit 205 may be activated temporarily in response to the door 120 being opened, to enable the appliance 100 to send a status message to the server 220. In addition to the wireless communications unit 205, one or more other parts of the appliance 100 may also be activated in response to the predetermined single user action, e.g. an image capture device such as a camera. An image of the contents of the appliance 100 may then be captured, and sent to the server 220 along with the status message. Thus, remote monitoring of the household appliance 100 can be performed. After sending the status message to the server 220, the wireless communications unit 205 may then be switched from the activated state to the de-activated state. This reduces power consumption compared to a case in which the wireless communications unit 205 is kept in the activated state.

In embodiments, the predetermined single user action is performed when the household appliance 100 is in a powered-on state and the wireless communications unit 205 is in the deactivated state. As such, the predetermined single user action does not comprise switching the household appliance 100 from a powered-off state to a powered-on state, according to embodiments. Rather, the household appliance 100 is already powered on when the predetermined single user action is performed. In embodiments, the method 400 comprises causing the wireless communications unit 205 to send a message via the wireless communications network to a server. The message indicates that the remote control mode of the household appliance 100 has been enabled. For example, the controller 310 may be configured to change a software flag in the memory 360 of the household appliance 100 when the remote control mode is enabled, and the household appliance 100 communicates the updated flag to the server. In response to receiving the message from the household appliance 100, the server permits remote control commands to be sent to the household appliance 100.

In embodiments, the method 400 comprises starting a timer when the wireless communications unit 205 is switched from the de-activated state to the activated state. In response to the timer indicating expiry of a predetermined time period, the wireless communications unit 205 is switched from the activated state to the de-activated state. This enables a reduction in power consumption compared to a case in which the wireless communications unit 205 is not de-activated after expiry of a predetermined time period. The predetermined time period may be one hour, one day, one week, etc. In embodiments, in response to the timer indicating expiry of the predetermined time period, the remote control mode of the household appliance 100 is disabled. A message may be conveyed to the user, e.g. via the user interface 150 of the household appliance 100, to inform the user that the remote control mode has been disabled.

In embodiments, prior to the timer indicating expiry of the predetermined time period, the timer is reset (e.g. re-started from zero or an initial time) in response to performance of a predetermined further user action to operate the household appliance 100. This enables remote control and/or remote monitoring of the household appliance 100 to continue after the predetermined time period has expired, thereby increasing the flexibility and/or functionality of the household appliance 100. The predetermined further user action and the predetermined single user action may comprise different user actions. For example, the predetermined single user action may comprise a user action to enable a remote control mode of the household appliance 100, whereas the predetermined further user action may comprise opening or closing the door 120 of the household appliance 100. In alternative embodiments, the predetermined further user action and the predetermined single user action comprise the same user action. The predetermined further user action may be performed directly on the household appliance 100, or may be performed remotely, e.g. based on user input received via the user equipment 230. In alternative embodiments, a timer is not started when the wireless communications unit 205 is switched from the de-activated state to the activated state, and/or the wireless communications unit 205 is not switched from the activated state to the de-activated state in response to expiry of a predetermined time period.

Figure 5 shows a schematic block diagram of the household appliance 100 according to embodiments.

The household appliance 100 comprises a user interface 150. The user interface 150 comprises a first button 510 and a second button 520. In embodiments, the user interface 150 comprises a touchscreen user interface. In some such embodiments, one or both of the first button 510 and the second button 520 comprise soft-key buttons.

The first button 510 comprises a multi-function button. In response to receipt of a single user input via the first button 510, a controller 310 of the household appliance 100 is configured to control the household appliance to: switch the wireless communications unit 205 of the household appliance 100 from a de-activated state to an activated state; and perform an additional operating activity of the household appliance 100. This provides a more efficient and/or user-friendly method of operating the household appliance 100. In embodiments, performing the additional operating activity comprises enabling a remote control mode of the household appliance 100. As such, a single user input via the first button 510 causes both the wireless communications unit 205 to be activated and the remote control mode to be enabled. Such a single user input comprises a single actuation of the first button 510. In alternative embodiments, performing the additional operating activity comprises enabling a remote monitoring mode of the household appliance 100. In alternative embodiments, performing the additional operating activity comprises setting a timer on the household appliance 100.

The second button 520 comprises a dedicated button actuatable to cause the wireless communications unit 205 to be switched from the activated state to the de-activated state and/or from the de-activated state to the activated state. The controller 310 is configured to switch the wireless communications unit 205 from the activated state to the de-activated state and/or from the de-activated state to the activated state in response to actuation of the second button 520. Therefore, in embodiments, the wireless communications unit 205 may be activated either by actuating the dedicated second button 520, the sole function of which is to change the activation state of the wireless communications unit 205, or by actuating the multi-function first button 510, which has an additional function in addition to changing the activation state of the wireless communications unit 205. This improves the flexibility and/or functionality of the household appliance 100. In embodiments, the second button 520 comprises a soft-key button that is operable to activate the wireless communications unit 205 using a menu. In such a case, actuation of the second button 520 to activate the wireless communications unit 205 has the sole function of causing the wireless communications unit 205 to be activated. That is, the household appliance 100 may have a dedicated “Wi-Fi on” input option in addition to a multi-function input option in which one of the functions is turning on Wi-Fi. The same soft-key button may be used for both input methods, e.g. firstly to select a dedicated “Wi-Fi on” option in a menu, and secondly to select a multi-function “remote control and Wi-Fi on” option in a different menu.

In alternative embodiments, the user interface 510 does not comprise the second button 520. As such, the second button 520 may be omitted. In either case, however, a user may cause the wireless communications unit 205 to be activated without having to actuate a dedicated button (or a dedicated input option on a menu), by instead actuating the multi-function button 510.

Figure 6 shows a schematic block diagram of the household appliance 100 according to embodiments.

The household appliance 100 comprises communications circuitry 605 switchable between an activated state, in which the communications circuitry is operable to transmit and receive data via a network (not shown), and a de-activated state. The communications circuitry 605 may comprise a wireless communications unit, such as the wireless communications unit 205 described with reference to Figure 2 above.

When the communications circuitry 605 is in the de-activated state, a controller 310 of the household appliance 100 is configured to receive a signal generated in response to performance of a user action directly on the household appliance 100 to turn on a remote access mode of the household appliance 100.

In response to receiving the signal, the controller 310 is configured to turn on the remote access mode, whereby remote control and/or remote monitoring of the household appliance is permitted, and switch the communications circuitry 605 from the de-activated state to the activated state, thereby enabling the household appliance 100 to transmit and/or receive data via the network for remote control and/or remote monitoring of the household appliance 100. In other words, the user action to turn on the remote access mode causes at least two operations to be performed by the controller 310: first, the communications circuitry 605 is activated; and second, the remote access mode is turned on. The communications circuitry 605, once activated, can then be used to operate the household appliance 100 in the remote access mode, e.g. to remotely control and/or monitor the household appliance 100.
