Abstract

PURPOSE: To warn the user to carry out cleaning by alarming in voice the clogging of filter for the balanced air circulator, etc.
CONSTITUTION: Cooling (heating) operation through the depressing of start switch SW1 is performed and at the same time a transistor Tr is turned on. As a result, terminal Q14 of integrated circuit 1 for counter is at "L" level, starting the count of operating time. If the operation is suspended, transistor Tr is turned off, stopping the count operation. However, the contents counted before the stop are kept intact. When the counted contents have reached "8192", the resumption of operation leads to the maintenance of the output of comparater IC2 at "H" level for a fixed time. During this period, signal P1 generates from "AND" gate AG1 and is inputted to the control for voice synthesis FC. If signal P1 is supplied, the voice "Filter is fouled" is sounded from the speaker SP.
