[0042] In order to solve the above problems, the present disclosure provides a method for controlling the authority of a household appliance and a household appliance. Figures 1 to 4 The permission control method for household appliances provided by the embodiments of the present disclosure is described in detail.

[0043] Figure 1 A flow chart of a method for controlling permissions of a household appliance provided by an embodiment of the present disclosure is shown.

[0044] In the embodiment of the present disclosure, the permission control method of the household appliance can be executed by the household appliance. For example, the household appliance can be an electric rice cooker, an induction cooker, an air fryer, a wall breaking machine, etc., which is not limited here.

[0045] like Figure 1 As shown, the permission control method of the household appliance may include the following steps.

[0046] S110. In response to detecting a data change operation, target data is changed, where the target data includes at least one of device code data or key data.

[0047] In an embodiment of the present disclosure, the home appliance may change target data in response to detecting a data change operation by a user.

[0048] Optionally, the data change operation may be an operation for a user to change a user bound to a home appliance.

[0049] Optionally, the target data may be data stored in the home appliance. For example, the target data may be data stored in the home appliance locally, in a database, or in a server, which is not limited here. The target data may include at least one of device code data or key data.

[0050] Optionally, the device code data may be an identification code corresponding to the home appliance.

[0051] Optionally, the key data may be secret information data used to complete cryptographic applications such as encryption, decryption, and integrity verification.

[0052] Specifically, when the user wants to change the bound user of a home appliance, a data change operation can be performed. In response to detecting the data change operation, the home appliance can change the target data stored in the home appliance, such as adding, deleting, overwriting or modifying, etc., which is not limited here.

[0053] Figure 2 A schematic diagram of a user binding process provided by an embodiment of the present disclosure is shown.

[0054] like Figure 2 As shown, after the home appliance leaves the factory, taking the electric cooker 202 as an example, the electric cooker 202 has not yet been bound by a user, and the user can scan the QR code 203 on the electric cooker 202 through the mobile terminal 201, such as the mobile phone, to bind, and the mobile terminal 201 can generate corresponding target data and send it to the electric cooker 202, so that the electric cooker 202 saves the target data and completes the user binding, and when other users want to bind the electric cooker 202, scanning the QR code 203 to bind is unsuccessful, therefore, when other users can change the bound user of the electric cooker 202 through the data change operation. Or when other users want to use the electric cooker 202, they can use the electric cooker 202 after applying for permission to use from the bound user after scanning the QR code 203.

[0055] S120, receiving write request data sent by the mobile terminal, and determining whether the write request data is correct and whether the target data is changed successfully.

[0056] In the disclosed embodiment, after changing the target data, the household appliance can receive the write request data sent by the mobile terminal, and determine whether the write request data is correct and whether the target data is changed successfully.

[0057] Optionally, the mobile terminal may be an electronic device such as a mobile phone, a tablet, a bracelet, etc., which is not limited here.

[0058] Optionally, the write request data may be a request for writing data to the home appliance.

[0059] For example, a user can use a mobile terminal to scan the QR code corresponding to a home appliance and send write request data to the home appliance. The home appliance can receive the write request data sent by the mobile terminal and determine whether the write request data is correct and whether the target data is changed successfully.

[0060] In some embodiments, the household appliance can determine whether the data included in the write request data is correct, such as determining whether the write request data carries corresponding target key data and target device code data. The target key data can be new key data, and the target device code data can be the device code data corresponding to the household appliance.

[0061] In other embodiments, the household appliance can also determine whether the target data has been changed successfully, such as the household appliance can determine whether the device code data or key data in the target data has been added, deleted, overwritten or modified.

[0062] S130. When the write request data is correct and the target data is changed, a write operation is performed on the write request data, and control authority of the mobile terminal is established.

[0063] In the disclosed embodiment, the home appliance can perform a write operation on the write request data and establish control authority for the mobile terminal when the write request data is correct and the target data is changed.

[0064] Optionally, the write operation may be an operation of writing and saving the data to be written.

[0065] Optionally, the control authority may be an authority to control the home appliance.

[0066] Specifically, after the household appliance judges the write request data and the target data, if it is judged that the write request data is correct and the target data is changed, the household appliance performs a write operation on the write request data, that is, the household appliance writes the write request data and saves it locally, in a database or on a server, etc. Then, the household appliance can establish control authority for the mobile terminal, so that the user can perform corresponding control over the household appliance through the mobile terminal.

[0067] S140: When the write request data is incorrect or the target data has not been changed, feedback of write rejection information is sent to the mobile terminal.

[0068] In the embodiment of the present disclosure, the home appliance may feedback write rejection information to the mobile terminal when the write request data is incorrect or the target data has not been changed.

[0069] Optionally, the write rejection information may be information for prompting the user that the write has failed.

[0070] The write rejection information may include at least one of target data change error information and write request data error information.

[0071] Optionally, the target data change error information may be information indicating that the target data has not been changed successfully.

[0072] Optionally, the write request data error information may be data indicating a data error included in the write request data.

[0073] Specifically, after the home appliance judges the write request data and the target data, if it is determined that the write request data is incorrect or the target data has not been changed, it means that data writing cannot be performed at this time, and the home appliance feeds back corresponding write rejection information to the mobile terminal. For example, when the target data change fails, target data change error information is fed back to the mobile terminal; when the write request data is incorrect, write request data error information is fed back to the mobile terminal; similarly, if both are wrong, target data change error information and write request data error information are returned at the same time.

[0074] Therefore, in the embodiment of the present disclosure, in response to detecting a data change operation, the target data of the household appliance can be changed, and then the write request data sent by the mobile terminal can be received, and when the write request data is correct and the target data is changed, the write request data can be written to establish control authority of the mobile terminal, thereby enabling user changes of the household appliance to be implemented more simply and conveniently without the need to apply for authority, thereby improving the sales power of the household appliance.

[0075] In some examples, if the data change operation is a factory restore operation, the target data is the device code data and the key data.

[0076] In the embodiment of the present disclosure, after the home appliance detects a data change operation, if the data change operation is a factory restore operation, it can be determined that the target data is the device code data and the key data.

[0077] Optionally, the factory restore operation may be an operation of changing all data saved in the home appliance.

[0078] Specifically, when the user performs a factory reset operation on a home appliance, the home appliance can determine that the target data that the user wants to change is the device code data and the key data.

[0079] Optionally, S110 may specifically include: in response to detecting a factory restore operation, at least one of deleting, overwriting or modifying the device code data and the key data.

[0080] In an embodiment of the present disclosure, in response to detecting a factory restore operation, the home appliance may at least delete, overwrite or modify the device code data and the key data.

[0081] Specifically, after receiving the factory restore operation, the home appliance can change all data stored in the home appliance, that is, change the device code data and the key data, such as deleting, overwriting or modifying the device code data and the key data, which is not limited here.

[0082] In a possible embodiment, after the user performs a factory restore, the home appliance does not save any data at this time. If the QR code is leaked, the user may maliciously write the QR code into other home appliances, resulting in a situation where one code is used for multiple devices.

[0083] Figure 3 A schematic diagram of a user control device provided by an embodiment of the present disclosure is shown.

[0084] like Figure 3 As shown, the first home appliance 304 and the second home appliance 305 use the same QR code 306 for user binding. When the first user controls the second home appliance 305 through the first mobile terminal 302, such as soup making control, barbecue control, etc., the first mobile terminal 302 will send the control to the second home appliance 305 and the cloud 303. Since the first home appliance 304 and the second home appliance 305 use the same QR code 306, the cloud 303 will synchronize the control to the second mobile terminal 301, thereby controlling the corresponding second home appliance 305 to perform the same operation, which poses a serious safety hazard.

[0085] Therefore, the above-mentioned factory restore operation is only performed by staff when the home appliance is undergoing after-sales service or internal debugging, thereby avoiding the situation where multiple machines have one code when the user performs the factory restore operation, thereby improving the safety of equipment use.

[0086] In other examples, if the data change operation is a key change operation, the target data is key data.

[0087] In the embodiment of the present disclosure, after the household appliance detects a data change operation, if the data change operation is a key change operation, it can be determined that the target data is key data.

[0088] Optionally, the key change operation may be an operation of changing key data in target data stored in the home appliance.

[0089] Specifically, when the user performs a key change operation on the home appliance, the home appliance can determine that the target data that the user wants to change is the key data.

[0090] Optionally, S110 may specifically include: in response to detecting a key change operation, at least one of deleting, overwriting or modifying the key data.

[0091] In the embodiment of the present disclosure, after detecting the key change operation, the household appliance can change the saved key data in response to the operation, such as deleting, overwriting or modifying at least one of the above, which is not limited here.

[0092] Therefore, in the disclosed embodiment, the bound user of the home appliance can be changed through a data change operation, so that when the home appliance is sold for the second time, there is no need to apply for permission, the operation is more convenient, faster, and safer, and the sales power of the home appliance is improved.

[0093] Optionally, after receiving the write request data sent by the terminal, the permission control method of the home appliance device may also include: judging whether the write request data meets the preset write condition and obtaining a judgment result; and feeding back a request result corresponding to the judgment result to the mobile terminal.

[0094] In the embodiment of the present disclosure, after receiving the write request data sent by the terminal, the home appliance can determine whether the write request data meets the preset write condition and obtain a determination result.

[0095] Optionally, the preset writing condition may be a pre-set writing condition.

[0096] The preset write condition may include: the write request data includes the target device code data, and the target device code data included in the write request data is the same as the device code data.

[0097] Optionally, the target device code data may be the device code data included in the write request data.

[0098] Optionally, the judgment result may be a result of judging the write request data.

[0099] Specifically, after receiving the write request data sent by the terminal, the household appliance can determine whether the write request data meets the preset write condition. The preset write condition may be that the write request data includes target device code data, and the target device code data included in the write request data is the same as the device code data, that is, the household appliance first determines whether the write request data includes the target device code, and whether the target device code is the same as the device code data of the household appliance, thereby obtaining a judgment result. For example, when the write request data includes the target device code and the target device code is the same as the device code data of the household appliance, the household appliance can determine that the write request data meets the preset write condition, that is, obtain a judgment result; when the write request data does not include the target device code or includes the target device code but the target device code is different from the device code data of the household appliance, the household appliance can determine that the write request data does not meet the preset write condition, that is, obtain a judgment result.

[0100] Furthermore, after obtaining the judgment result, the household appliance can feed back a request result corresponding to the judgment result to the mobile terminal.

[0101] In some examples, after obtaining the judgment result, if the household appliance determines that the write request data meets the preset write condition, it will feedback the corresponding request result to the mobile terminal, such as allowing writing.

[0102] In other examples, after obtaining the judgment result, if the household appliance determines that the write request data does not meet the preset write condition, it will feedback the corresponding request result to the mobile terminal, such as not allowing writing.

[0103] Optionally, after S130, the permission control method for the household appliance may further include: establishing a communication connection with a mobile terminal.

[0104] In the embodiment of the present disclosure, after establishing control authority with the terminal, the home appliance can establish a communication connection with the mobile terminal.

[0105] Optionally, the communication connection may be a connection for communication between two devices.

[0106] Specifically, after establishing control authority with the terminal, the home appliance can establish a communication connection with the mobile terminal. For example, the home appliance can directly establish a communication connection with the mobile terminal, and the mobile terminal can directly send corresponding communication information to the home appliance through the communication connection, such as control information, request information, etc.; for another example, the home appliance can establish a communication connection with the mobile terminal through the cloud, and the cloud forwards the communication information between the home appliance and the mobile terminal.

[0107] Figure 4 A schematic diagram of a user change process provided by an embodiment of the present disclosure is shown.

[0108] like Figure 4 As shown, the home appliance device already has a bound user. When the bound user gives away or sells the home appliance device, the new user can perform data change operations on the home appliance device, and the home appliance device can change the target data. Then the new user sends the write request data through the mobile terminal, that is, writes by scanning the QR code. When the write request data is correct and the target data is changed, the home appliance device writes the write request data and establishes control authority for the mobile terminal, so that the bound user is changed, and the new bound user is the new user.
