The present disclosure relates to a device and a method for upgrading a home appliance.
Home appliances comprise a control unit. The control unit executes specific software to embody a function desired by the user.
Ordinarily, in the case where firmware is upgraded to improve an error and the like of software, or a plurality of firmware is upgraded to a plurality of micoms, a conventional home appliance upgrades first software to a first micom, as the first software is downloaded successfully. Then in the case where the first software is upgraded successfully, second software for upgrading a second micom is down loaded. If the download of the second software fails because of an effect of a network environment (e.g., a wireless network environment), the home appliance notifies the user that the upgrade fails.
Additionally, as the home appliance fails to upgrade the second software, the upgrade of the second micom to the Nth micom may not be completed. Further, the home appliance may not operate due to the non-completion of the upgrade.
In the case where the conventional home appliance repeats a download procedure and an upgrade procedure, and a failure of the wireless network occurs, entire software may not be upgraded, causing a failure in the upgrade or an impossibility of the operation of the home appliance.
Further, since the home appliance is rebooted to complete an upgrade of single firmware, the home appliance needs to be repeatedly rebooted a number of times.
Thus, despite an unstable wireless network environment, the software of the home appliance needs to be upgraded reliably.
Furthermore, a new function for upgrading the home appliance is not added after the home appliance is launched, causing a failure in meeting the needs and a consumer and a failure in responding to a technical change.
Conventionally, a download of software of a home appliance, and an upgrade of downloaded software are repeated, resulting in a failure in the upgrade of entire software.
In the present disclosure, provided are a system and a method for upgrading software, in which software is downloaded consecutively, and then the home appliance is upgraded.
