New OEM Differential Sensor Detects Dryer Clogging
Lint-Alert – U.S. Patent 6,785,981 Sku: DLS121
(Jupiter, FL - March 2006) In-O-Vate Technologies, Inc., a manufacturing company specializing in dryer venting products, recently unveiled the Lint-Alert, an electromechanical pressure switch to be installed in the dryer appliance. Collaborating with World Magnetics of Michigan, the DesignFlex pressure switch mates with In-O-Vate’s specially designed pitot tube receptor that slides and snaps into place in the dryer’s exhaust conduit.

Measuring the pressure differential within the clothes dryer exhaust conduit and atmosphere, the device will detect and notify the appliance user of any blockage. The U.L. approved switch would be an OEM component installed in the exhaust conduit of the dryer near its exit. The switch exhibits a contamination-free pitot tube pickup and a creative design that allows for a slide-n-snap insertion. At approximately .91 water column inch (wci), the switch would trigger an audible or visual alert on the control panel that maintenance or attention should be directed to the exhaust conduit of the dryer.

Potential maintenance issues include the buildup of lint due to the condensation and moist air in the pipe, the potential of the flex being crushed or kinked creating a “bottleneck” situation, bird or rodent nests near the exhaust termination cutting off air flow, screens within the termination hoods allowing lint to accumulate over time and inoperative dampers.

“This brand new and recently patented pressure differential switch is a common sense innovative safety device that has huge potential in saving lives and property,” said Rick Harpenau, the inventor.

The U.S. Consumer Product Safety Commission estimates that 15,500 clothes dryer fires occur in U.S. homes annually, averaging about 10 deaths and 300 injuries and $85 million in direct property damage. In 30 percent of the cases, lack of maintenance was the leading cause of these fires.

“The dryer is a common and frequent ignition source in household fires. Property damage, injuries, fatalities, insurance costs could all be reduced with this simple inexpensive product,” Harpenau said.

The new module has recently been introduced to all the major appliance manufacturers and is available now.
