Smart ovens are no longer unchanging tools. When there are new features and applications, users can connect to WiFi at the oven end, easily complete upgrades at home, and get the latest software version of the oven. When the oven has a fault that needs to be solved by upgrading the program, there is no need for professional personnel to come to the door for service. This not only saves the user's time, but also reduces the manufacturer's door-to-door service costs.
