Household appliance with alarm warning device.

摘要

The appliance includes a control device capable of generating an alarm signal and a transmitter actuated by the alarm signal for transmitting a control signal to a remote receiver which in turn can operate a warning device in response to the control signal. The appliance is e.g. a deep freezer which generates the alarm signal if it does not operate correctly. Pref., the transmitter comprises an oscillator whose output is connected with the mains supply and the remote receiver comprises a decoder whose input is connected with the mains and whose output operates the warning device. The oscillator normally generates a coded reference signal and is turned off in response to the alarm signal, the decoder being actuated when the coded reference signal ceases.
