Abstract
An air flow detecting system is provided for monitoring air flow in a dryer system. The dryer system has an exhaust passage through which air from a drying compartment flows. The air flow detecting system includes a detector for monitoring a rate at which air from the drying compartment travels through the exhaust passage, and a signal generator. The signal generator is responsive to the detector and generates an electrical signal for which at least one of phase, frequency, voltage, or current varies over a continuous range based on a measured flow rate.
Claims17
A dryer system comprising:
- a drying compartment for holding articles to be dried;
- a heater providing heat to said drying compartment to assist in drying the articles;
- an exhaust passage discharging air from said drying compartment at an air flow rate;
- a detecting system monitoring said air flow rate through said exhaust passage;
- and
- a processor controlling operation of said dryer system based on an output of said detecting system identifying said air flow rate.
An air flow detecting apparatus for monitoring air flow in a dryer system, said dryer system having an exhaust passage through which air from a drying compartment flows, said air flow detecting apparatus comprising:
- a detector directly monitoring a rate at which air from the drying compartment travels through an exhaust passage;
- and
- a signal generator responsive to said detector for generating an electrical signal, for which at least one of phase, frequency, voltage, or current varies over a continuous range based on a measured air flow rate.
