Title: Chattering prevention device
Inventor: OHASHI EIJI
IPC: H01H9/54
Filed: 1995-01-30
Abstract: PURPOSE: To prevent chattering of the magnet switch of an air conditioner to prevent seizure of a compressor by causing a chattering prevention means to hold the magnet switch in an open state when chattering detection signals have been output for a predetermined time or longer. CONSTITUTION: A controller 7 sets a chattering prevention process counter at N=0. The controller 7 then determines whether or not the requirements for turning a compressor 2 on are met. When the requirements are not met, a magnet switch 3 is kept open (off). When the requirements are met, the controller 7 holds the switch 3 in a closed state and outputs a start signal S start for the compressor 2 to the switch 3 to hold the switch 3 closed. A determining circuit 6 determines whether or not the switch 3 is chattering. When no chattering detection signal is output, operation is continued. When the switch 3 is chattering and the chattering detection signals have been output three times or more (N>3), the switch 3 is held open.
