Abstract
A dryer venting system comprising a motor powered fan for connection in-line with the exhaust of the dryer; a sensor to sense operation of the dryer venting system; a dryer disabling device; and a controller configured to monitor a sensed operation of the dryer venting system as sensed by the sensor and to monitor for operation of the dryer, the controller configured to cause the dryer disabling device to disable the dryer when the sensed operation indicates that the dryer venting system is operating improperly and to cause the fan to turn on when the dryer is operating.
Claims10
A dryer venting system for use with a dryer having an exhaust, the system comprising:
- a motor powered fan for connection in-line with the exhaust of the dryer;
- a sensor to sense operation of the dryer venting system;
- a dryer disabling device;
- and
- a controller configured to monitor a sensed operation of the dryer venting system as sensed by the sensor and to monitor for operation of the dryer, the controller configured to cause the dryer disabling device to disable the dryer when the sensed operation indicates that the dryer venting system is operating improperly and to cause the fan to turn on when the dryer is operating.
A booster fan system for connection in-line with the exhaust vent of a dryer, comprising a booster fan, a current sensor sensing operation of the booster fan, and a controller, the controller automatically monitoring operation of the booster fan as sensed by the current sensor and generating a signal when the current sensor indicates improper operation of the booster fan.
A method for use with a dryer having a dryer venting system that includes a booster fan, the method comprising the steps of:
- while the dryer is running, continuously automatically monitoring operation of the dryer venting system,
- while the dryer is running, continuously automatically determining if the dryer venting system is operating improperly, and
- if it is determined that the dryer venting system is operating improperly while the dryer is running then automatically disabling the dryer,
- wherein the operation of the booster fan is continuously automatically monitored, and continuously automatically determined as part of the steps of continuously automatically monitoring operation of the dryer venting system and continuously automatically determining if the dryer venting system is operating improperly.
