Abstract (en)
[origin: EP1923500A2] According to the present invention, a highly safe dry cleaner is provided, which ensures safety without the danger of ignition in a drying process even if so-called microcomputer runaway occurs. The dry cleaner includes a relay sequence controlling circuit (71). The relay sequence controlling circuit (71) includes a serial connection of a first valve (V27) to be controlled, a first switch (77) which controls the turn-on of the first valve (V27) and a second contact (76a) provided in a second relay (76). A detection circuit (79) which controls the second contact (76a) is connected to the serial connection. Thus, the first valve (V27) is maintained in an inactive state irrespective of a first switch turn-on control performed by a control section (81) until the detection circuit (79) performs a predetermined operation to turn on the second contact 76a.
