A home appliance includes a controlled assembly, a control module, and a signal converter. The control module is electrically connected to the controlled assembly, and the control module has a port for receiving an electrical signal. The control module controls the controlled assembly according to the electrical signal received through the port. The signal converter receives a wireless control signal, and converts the wireless control signal into the electrical signal to be transmitted to the port. The signal converter is selected from a plurality of signal converters which respectively convert signals of different types. While assembling, the signal converter is connected to the port, which makes the control module and the connected signal converter constitute a control device of the home appliance. Whereby, the inventory pressure of control devices can be reduced for manufacturers.
