The home appliance performs integrity check on the module firmware package in a centralized manner, and the check process is simplified.
The above embodiments are described taking a washing machine as an example. For example: the functional module to be upgraded of the washing machine comprises a main board, a display module and a networking module. In the upgrading process, after the downloading task of all the module firmware packages is completed, the washing machine performs integrity check on the main board firmware packages, the display module firmware packages and the networking module firmware packages, and downloads the main board firmware packages and the display modules again under the condition that the main board firmware packages and the display module firmware packages are not checked successfully until the downloading task of the module firmware packages is completed after the checking of all the module firmware packages is completed successfully.
