Abstract
A telephone-controlled home appliance system and a method for controlling the same are provided. Thus, a remote user can remotely control a plurality of home appliances inside of a home using a remote telephone. A telephone control module is contained in each of the home appliances to detect ringing signals received over a telephone line. If the number of the detected ringing signals is equal to a predetermined reference value, each home appliance automatically enters an off-hook state to make a call connection with the remote telephone. Even though a plurality of telephone jacks are commonly connected to the telephone line and the home appliances are in turn connected to respective telephone jacks, the user can access the respective home appliances from a remote site to simultaneously/individually control them. Therefore, the plurality of home appliances can be remotely controlled over the telephone line in a simple manner.
