Benefits of technology

The present patent is about a safety system for clothes dryers to prevent fires and damage caused by lint accumulation. The system includes a specialized printed circuit board that monitors and tracks usage of the dryer, and a control module that can disable the heating source if the usage total exceeds certain criteria. The system can also include a warning indicator and a service required light to alert the user and prompt them to service the dryer. The technical effect of this patent is to provide a safer and effective way to prevent accidents and damage caused by lint accumulation in clothes dryers.

Problems solved by technology

The lack of heat will still tumble dry the clothing but the poor performance will prompt the user to service their dryer.

Abstract

A clothes dryer including a cabinet, a drum rotatably mounted in the cabinet, ductwork connected to the drum for circulating air, a heating element for providing heat to the drum, and a control system for operating the clothes dryer. The control system includes a warning indicator and a control module. The control module monitors and tracks usage of the clothes dryer. The warning indicator provides first and second warnings to a user based on the usage. The first warning indicates that factory authorized service is required to clean inside the cabinet of the clothes dryer, and the second warning indicates that the heating element has been disabled until the factory authorized service occurs. Preferably, the control module is further operative to completely disable the clothes dryer based on the usage.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to U.S. Provisional Patent Application No. 62 / 303,897, filed Mar. 4, 2016, which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The subject disclosure relates to safety mechanisms for clothes dryers, and more particularly to clothes dryer safety mechanisms that disable the heating element or operation when maintenance is overdue by a predetermined amount of cycles and / or runtime.[0004]2. Background of the Related Art[0005]Clothes dryer fires are common events, which often result in loss of property and endanger life. Typically, not only the vents and ductwork but everywhere inside the cabinet becomes clogged with lint. For example, factors such as design, installation, use and maintenance can result in lint accumulation near the heat sources such as the electric heating element and gas burners. Lint is an excellent fuel for fire so that when left in proxi...
