Coffee maker.

摘要

An AC power source (5) is coupled with a heater circuit (A) containing a series circuit including a cover switch (1) for a coffee maker, a thermal switch (3) for controlling the temperature of a heating unit and a control switch (4a) for turning on and off a heater (2) of the heating unit. A detecting circuit (10) is connected between a signal take-out node (11) as a junction point between the heater and the thermal switch and one end of the AC power source. The detecting circuit responds to a given on-off states of each of the switches to receive a detection current (S1) from the signal take-out node, and produces a detection signal (S2) for controlling a control apparatus for the coffee maker.
