The above embodiments are explained by taking a washing machine as an example. For example: the washing machine function module to be upgraded comprises a mainboard, a display module and a networking module, and the type of the module is set to be the networking module. In the upgrading process, the networking module is used for transferring and temporarily storing, and the networking module acquires an upgrading file from a server so as to upgrade non-networking modules (such as a mainboard and a display module) in the whole machine. When the networking module and other modules need to be upgraded at the same time, the networking module is upgraded firstly to improve the acquisition rate of the firmware packages of other modules, so that the upgrading efficiency of other modules is improved, and the firmware packages of the networking module are downloaded again under the condition that the integrity check of the networking module is not passed, so that the upgrading of the networking module is completed successfully.

The module firmware package may be lost, error-coded or tampered in the transmission process, so that in order to ensure that the module can be successfully upgraded, the integrity of the firmware package needs to be checked before the upgrade task is completed according to the module firmware package, and the firmware package is downloaded again under the condition that the check fails so as to avoid upgrade failure caused by loss, error-coded or tampered. And after the downloading of each module firmware package is finished, the module firmware package is checked in time, so that the upgrading efficiency can be improved.
The above embodiments are explained by taking a washing machine as an example. For example: the washing machine function module to be upgraded comprises a mainboard, a display module and a networking module. In the upgrading process, the washing machine downloads the module firmware packages in sequence according to the priority, or the washing machine performs integrity check after downloading of each module firmware package is completed under the condition that the washing machine supports a single downloading task in the same time period, so that the timeliness of the check and the upgrading speed are improved. Under the conditions that the priority of the networking module is highest and the priority of the display module is lowest, integrity verification is carried out on the networking module firmware package after the networking module firmware package is downloaded, the networking module firmware package is downloaded again when the networking module firmware package is not downloaded, and the mainboard firmware package is downloaded after the networking module firmware package is verified; after the mainboard firmware package is downloaded, carrying out integrity verification on the mainboard firmware package, if the mainboard firmware package is not passed, downloading the mainboard firmware package again, and after the mainboard firmware package passes the verification, downloading the display module firmware package; and after the display module firmware package is downloaded, carrying out integrity verification on the display module firmware package, and if the display module firmware package does not pass the integrity verification, downloading the display module firmware package again until the verification passes.

The household appliance equipment performs integrity check on the module firmware package in a centralized manner, and the check process is simplified.
The above embodiments are explained by taking a washing machine as an example. For example: the washing machine function module to be upgraded comprises a mainboard, a display module and a networking module. In the upgrading process, after the washing machine finishes all module firmware package downloading tasks, integrity verification is carried out on the mainboard firmware package, the display module firmware package and the networking module firmware package, and under the condition that the mainboard firmware package and the display module firmware package are not successfully verified, the mainboard firmware package and the display module are downloaded again until all module firmware package verification successfully finishes the module firmware package downloading tasks.
In some embodiments, the method further comprises: recording a downloading interruption position under the condition that interruption occurs in the process of acquiring the module firmware package; and in the case of network recovery, continuously acquiring the module firmware package based on the recorded download interruption position.
