 According to an embodiment of the present invention, there is provided a method of controlling charging of a device for charging a device to be charged by means of an electromagnetic conversion unit of the electrical device.

 As shown in FIG. 1, the method for controlling charging of a device according to an embodiment of the present invention includes: Step S101: If the electrical device is operated in a first operating state (for example, a normal working state), and the device to be charged is required to be charged, the electrical device The device supplies power to the electromagnetic conversion unit;

Step S103, if the electrical device needs to enter the second operating state from the first operating state (eg, For example, in the standby state, the electrical device determines whether it is necessary to charge the charging device, and if the determination result is YES, continues to supply power to the electromagnetic conversion unit.

 By means of the above-described processing, by generating a magnetic field by the electromagnetic conversion unit of the electric device, it is possible to control the charging of the device to be charged in a wireless manner (magnetic induction), thereby being able to be treated without the conditions of a socket, a socket, and a charger. The charged device is charged, overcomes the limitation of charging under various conditions in the related art, and can charge the charging device simply and easily, thereby effectively improving the user experience.

 Wherein, in the case that the first operating state is the working state, if the default configuration in the working state is that the charging device is required to be charged, or the charging instruction is received during the working state of the electrical device, the electrical device determines that it needs to be in the first Charge the charging device under working conditions. That is to say, for the sake of convenience, on the one hand, the electrical device can be configured to always supply power to the electromagnetic conversion unit in the working state, so that the user places the device to be charged in the vicinity of the electromagnetic conversion unit of the electrical device (for example, electromagnetic The conversion unit is disposed in the electrical device, for example, in the base of the television, and the device to be charged, for example, a mobile phone, etc., can be placed at a position near the electromagnetic conversion unit of the television base), and the electrical device can charge the charging device unless The electrical device receives the indication and turns off the charging function; on the other hand, the electrical device can also be configured to not supply power to the electromagnetic conversion unit by default in the working state, and then start to supply power to the electromagnetic conversion unit after the user issues a charging command.

 In the case that the electrical device needs to enter the second operating state from the first operating state, if the electrical device receives the charging command (can be issued by the user pressing a button on the remote controller, the user can also press the button on the electrical device to issue the button) , the electrical device determines that the charging device needs to be charged in the second operating state.

 In the case where the second operating state is the standby state, if the electrical device determines that the device to be charged needs to be charged in the standby state (for example, receiving a charging command when it is required to enter the standby state), the electrical device enters a standby state and maintains Power to the electromagnetic conversion unit.

That is to say, in the standby charging mode, the electrical equipment will be in the standby state, but as long as there is a demand for charging, the relevant components responsible for charging of the electrical equipment will be operated (started), and other components remain in the standby state, thereby Reduce the energy consumption of electrical equipment while charging other equipment that needs to be charged. Optionally, during the standby charging mode, the power indicator can To turn on or flash.

 In addition, usually many electrical equipment will automatically enter standby after a period of automatic operation (or no command, or input signal for a period of time). In order to avoid the automatic standby of the electrical equipment, the charging process is terminated, and the electrical equipment is set to In the case of the standby charging mode, the control unit in the electrical device (e.g., may be a microprocessor unit (MCU), optionally located in the movement of the electrical device) may inhibit its automatic standby function from starting.

 For example, for a television set, when the television is placed in a standby state, the processor in the television can turn off the picture, backlight, sound, etc., thereby putting the television into a standby state.

 Correspondingly, when the user issues an instruction to enable the electrical device to start up and operate normally, the electrical device will turn on the backlight and the sound again, and may not play the boot LOGO, nor activate the boot eye function, thus, with the real standby and then the power on. In contrast, the boot speed will be faster.

 In addition, during the power supply to the electromagnetic conversion unit while the electrical device is in the standby state, if the power-on command is received, and the charging end time corresponding to the charging mode does not arrive, the electrical device enters the working state, and the electromagnetic conversion unit is continuously powered. In addition, if the power-on time has been set before the standby charging mode is set, the corresponding function will be executed first, for example, the working state can be first entered, and the electromagnetic conversion unit can continue to be powered. Charging), knowing that the charging is over; if the charging end time is earlier than the preset power-on time, the electrical equipment will stop supplying power to the electromagnetic conversion unit (stop charging), and then enter the normal working state when the power-on time is reached; If the power-on time arrives at the same time as the standby charging mode time, it will be turned on when it arrives (as above, turn on the backlight, sound, etc.) and cancel the standby charging mode function.

 In addition, in a case where the first operating state is the working state, the second operating state is the standby state, and the electrical device needs to charge the charging device in the second operating state, the electrical device determines whether it is set with the timed shutdown function or The timed sleep function, if the judgment result is yes, the electrical device cancels the set timed shutdown function or the timed sleep function, and supplies power to the electromagnetic conversion unit in the standby state; if the electrical device determines that the timed shutdown function and the timed sleep function are not set Therefore, the electrical equipment supplies power to the electromagnetic conversion unit in the standby state.

In addition, preferably, before the user sets the charging mode function, if the timer shutdown or timed sleep function has been set, after the user selects the charging mode, the charging mode function may also be used. The standard shall prevail. Specifically, suppose that the user sets the electrical device to automatically shut down after two hours (ie, 3 o'clock) at 1 o'clock, and after one hour (at 2 o'clock), the user activates the charging function of the electrical device, and selects the charging mode. For 2 hours, in this case, the electrical device will not shut down when it arrives at 3 o'clock, but will shut down after 4 o'clock charging (if the user does not have additional charging mode).

 In addition, taking a TV as an example, its total power supply (also referred to as the whole machine power supply) provides 24V and 12V supply voltages, of which 24V is supplied to the backlight of the display, and 12V can be changed by the boost circuit module. For 18V, a voltage of 18V is supplied to the electromagnetic conversion unit, so that the electromagnetic conversion unit on the television generates a magnetic field, thereby charging the device to be charged.

 For other electrical equipment, the electromagnetic conversion unit can be powered in a similar way to generate a magnetic field, and the voltage of the power supply can be flexibly designed according to actual needs.

 Optionally, when determining the charging mode, there are many specific determination manners. For example, the charging mode may be determined according to the charging mode indication carried in the charging instruction, where the charging mode indication is used to identify the charging mode; specifically, the electrical device or A button corresponding to each charging mode can be disposed on the remote controller. When the user presses one of the buttons, the electrical device receives the charging command and can know the charging mode corresponding to the button.

 In addition, multiple charging mode options can be configured on the electrical device (these options can be displayed through the interface), each time a charging command is received (the user can press the charging button on the electrical device or its remote control to issue the command) When the electrical device can switch to the next charging mode option (for example, it can be switched by moving the cursor) until receiving a confirmation command indicating that one of the charging mode options is selected, the charging mode corresponding to the selected charging mode option is taken as Determined charging mode.

For example, suppose charging mode option 1 corresponds to charging mode 1, charging mode option 2 corresponds to charging mode 2, and charging mode option 1 is sorted prior to charging mode option 2, at this time, if the user presses the remote control or the electrical device When charging the button, the electrical device can display charging mode option 1 and charging mode option 2, and display the description of the charging mode corresponding to the two charging options. At this time, the cursor will stay at charging mode option 1; when the user presses charging again When the button is pressed, the cursor will move to the charging mode option 2; when the user presses the charging button for the third time, due to charging Mode option 1 and charging mode option 2 are cyclically arranged, so the cursor will return to charging mode option 1; if the user presses the OK button at this time, the electrical device will charge the charging device in charging mode 1.

 In order to facilitate the user's operation, the option to turn off the charging can also be used as a charging mode option, so that even if the user erroneously presses the charging button, the charging mode selection interface can be jumped out by selecting the option to turn off the charging, thereby facilitating the user. Use to further enhance the user experience.

 After the electrical device supplies power to the electromagnetic conversion unit according to the charging mode, the magnetoelectric conversion unit on the device to be charged uses the magnetic field generated by the electromagnetic conversion unit to charge the charging device. Specifically, the magnetoelectric conversion unit on the device to be charged generates electric energy under the action of a magnetic field generated by the electromagnetic conversion unit, thereby charging the device to be charged.

 Preferably, the charging mode includes a length of time during which charging is performed. At this time, the above charging mode

1 can be "Charging for 30 minutes" and charging mode 2 can be "Charging for 1 hour". It should be understood that the number of charging modes and the time corresponding to each charging mode can be flexibly configured as needed, as long as the electrical device can recognize the command and correctly select the corresponding charging mode.

 In addition, the charging mode can be distinguished by other parameters than the charging time. Other expressions of the charging mode are not listed here.

 3 is a flow chart showing an example of processing of a charging control method according to an embodiment of the present invention. As shown in FIG. 3, in this example, the charging control method of the present invention may include the following steps:

 First, if the user presses the charging mode function button after the TV is turned on (ie, the above charging button, the button can be set on the remote controller of the television or on the television;); after pressing the button , the charging mode screen display is called, wherein the screen display at this time may include an option of multiple charging modes, and further includes an option to turn off the charging mode;

After that, it is determined whether the user selects the charging mode. If the user selects a charging mode, the selected charging mode is turned on (turned on or activated) to charge the device that needs to be charged; if the user chooses to turn off the charging mode, the television can stop treating The charging device performs charging; whether or not the user selects the charging mode, it is necessary to detect whether the standby charging mode is turned on when the television starts to stand by; If the TV is turned on in the standby charging mode, the MCU of the TV can control to turn off the backlight and sound of the TV, and turn on the power light on the TV; if the TV does not turn on the standby charging mode, stop the power supply to the electromagnetic conversion unit. Processing ends;

 Moreover, if the TV is turned on in the standby charging mode, when the TV enters standby, the MCU of the TV can disable the auto standby function of the TV when there is no signal, thereby preventing the TV from automatically turning off the charging function, ensuring that the charging process is not interrupted. ;

 After that, it can be determined whether the user has set the timed shutdown or timed sleep function for the TV; if the timed shutdown or timed sleep function is set, the timed shutdown and timed sleep functions are cancelled accordingly; if the timed shutdown and the timed sleep function are not Set, then charge the device that needs to be charged;

 When the user presses the standby button or the program plus/program minus button that can change the television from the standby state to the normal running state, it is determined that the user instructs the television to turn on, and at this time, it is necessary to turn on the backlight, the sound, and turn off the television power light. The no-signal auto-standby function is activated, and the standby charging mode is turned off. If the user does not instruct the power-on, but the user sets the power-on time and the time has arrived, the backlight, the sound, the TV power-off light, and the no-signal automatic standby are also turned on. Function, and turn off the standby charging mode;

 If the user neither instructs the power on, and the user does not set the power-on time or the set power-on time has not arrived, the charging will continue, and wait for the user to indicate the power-on or wait for the power-on time to arrive, if the charging time has arrived (ie, charging) When finished, the TV will turn off the standby charging mode, the TV will stand by, and the process ends. In this embodiment, when the television is in the normal playing state, the power supply to the electromagnetic conversion unit is not limited by whether the standby charging mode is turned on, and the power module can always supply power to the electromagnetic conversion unit.

As described above, by the above-described processing, by generating a magnetic field by the electromagnetic conversion unit of the electric device, it is possible to charge the device to be charged in a wireless manner (magnetoelectric induction), thereby enabling conditions such as without using a socket, a socket, and a charger. In the case of charging the device to be charged, overcoming the limitation of charging under various conditions in the related art, the charging device can be easily and easily charged, thereby effectively improving the user experience; in addition, the related art needs to perform charging of the device. The insertion or removal of wires or batteries not only presents the risk of electric shock, but may also cause the user to think that the device is charging but the device is not being charged due to factors such as poor contact. By means of wireless charging, the safety of charging can be improved, and the problem of charging misoperation can also be avoided; in addition, the above electrical equipment can be a device that a user such as a television, a computer, etc. often uses, so that when the user is using these When the electrical equipment is used, it is possible to put a device such as a mobile phone that needs to be charged, which does not affect the user's use of the television, the computer, etc., and can also bring the charging device such as the mobile phone close to the user, and can watch TV or use without interruption. In the case of a computer, the use of a mobile phone for communication further facilitates the daily use of the user.

 According to an embodiment of the invention, an electrical device is also provided.

 As shown in FIG. 3, an electric appliance such as a television according to an embodiment of the present invention includes a power module 31, an electromagnetic conversion unit 32, and a control module 33. The power module 31 is connected to the electromagnetic conversion unit 32 and the control module 33.

 The power module 31 is used to supply power to the electromagnetic conversion unit 32, and the electromagnetic conversion unit 32 is configured to generate a magnetic field to charge the device to be charged when power is supplied.

 The control module (which may be the above-mentioned MCU or a part thereof) 33 is used for determining the operating state of the electrical device and whether charging of the device to be charged is required in the operating state; wherein if the electrical device is operated in the first operating state ( For example, if the television is in the normal playing state, and the charging device is to be charged, the control module 33 controls the power module 31 to supply power to the electromagnetic conversion unit 32; if the electrical device needs to enter the second operating state from the first operating state, then control The module 33 determines whether charging of the device to be charged is required, and if the determination result is YES, the control power module 31 continues to supply power to the electromagnetic conversion unit 32, and turns off other modules, such as backlight, speaker, and display of the television. The power of the screen.

Moreover, the state control of the standby charging mode and the standby mode of the electrical device may be completed by the control module 33, wherein the control module 33 may be connected to the power source of the electrical device, and the power source may be in the electrical device under the control of the control module 33. The various components (for example, for a television set, which may include a backlight, a speaker, a display, etc.) are powered (the power source may be the power module described above, and the power module may also be part of the power source). The control module 33 instructs the power module 31 to supply power to the electromagnetic conversion unit 32 by controlling the level of the control signal corresponding to the electromagnetic conversion unit 32 that is sent to the power module 31. And, specifically, the control module 33 can be connected to the power source through the bus, and provide a control signal to the power source, and for each component that needs to control the power supply, a corresponding signal line can be configured, for example, for the electric In the case of a video camera, a signal line corresponding to a display screen, a speaker, a backlight, or the like can be set, and a signal line corresponding to the electromagnetic conversion unit can be set, and when the television is in an operating state, the level of all the signal lines can be set to A high level means that power is required for these components; and when entering the standby state, if it is still necessary to supply power to the electromagnetic conversion unit, the level of the signal line corresponding to the electromagnetic conversion unit can be kept high, and The level of the signal line of the backlight, speaker, display, etc. is set low. At this time, the TV will supply power to the electromagnetic conversion unit, and the power supply will be stopped for components such as backlight, speaker, and display. Then, if the TV enters the normal working mode, the control module can reset the level of the corresponding signal line of the backlight, the speaker, the display, etc. to a high level, and restore the power supply to the backlight, the speaker, the display, and the like. If the user wishes to stop charging and continues to watch the program, the control module can set the level of the signal line corresponding to the electromagnetic conversion unit to a low level, thereby stopping the supply of power to the electromagnetic conversion unit.

 By flexibly controlling the power supply or stopping the power supply, the television can determine whether to supply power to the electromagnetic conversion unit according to the user's instruction in various states. For example, the television can enter the listening mode (only the speaker and the audio decoding component work, The display does not display any images), and in this case, the TV can also stop or continue charging the charging device according to the user's settings.

 In addition, the selection process of the above charging mode can also be completed by the control module and the display screen of the electrical device.
