Benefits of technology
This patent is for a system that includes a dryer, a temperature sensor to measure the temperature inside the dryer or associated ductwork, an air flow sensor to measure the air flow from the dryer or through the ductwork, and a fire suppression system to suppress any fires within the dryer or ductwork. The temperature sensor can be coupled to an alarm system that can trigger the fire suppression system, which can be a powder fire suppression system or an inert gas fire suppression system. The system can also include an audible and visible alarm to alert users, and a data communications transmitter or receiver to send and receive information about the system. The technical effect of this patent is to provide a system that can prevent damaging fire outbreaks in dryers and associated ductwork, which can cause significant damage and downtime.
Problems solved by technology
On average these fires cause 9 deaths, 444 injuries, and $238 million dollars in property damage each year according to the National Fire Protection Association.

examples
[0031]Various experiments were performed to demonstrate the feasibility of the system.
[0032]First, the issue of overheating was examined. To test the use of temperature sensors at various locations in the dryer, the inventors repurposed a meat thermometer used for grilling as a temperature probe. The temperature probe could be placed at key locations in the dryer, and by adjusting the alarm temperature to go off at the maximum safe level for a dryer to work properly, the internal temperature of the dryer was monitored. For purposes of the experiment, a threshold below the operating temperature of the dryer was set. The temperature sensor was placed at various locations in the dryer and triggered an alarm when the temperature exceeded the threshold that was set for the experiment. Moreover, the temperature probe could be linked to a smartphone. When linked, the system sounded an audible alert at the dryer as well as sending a notice to the linked device, informing the operator that t...

Described herein is a system for detecting, preventing, and suppressing dryer fires using temperature probes coupled to an alarm system, air flow monitoring, and localized fire suppression. The components of the system are positioned and integrated with each other to prevent and, if necessary, detect and suppress localized fires that may occur in commercial or residential fabric drying machines (i.e., dryers).
Description
FIELD OF THE DISCLOSURE[0001]This disclosure relates to a system for detecting, preventing, and suppressing fires in fabric-drying machines.BACKGROUND[0002]U.S. fire departments respond to an estimated average of 14,692 home structure fires involving clothes dryers annually. On average these fires cause 9 deaths, 444 injuries, and $238 million dollars in property damage each year according to the National Fire Protection Association. Additionally, scientists at Worcester Polytechnical Institute have studied the environmental impacts of such fires on air pollution, water contamination, and release of toxic substances. A need exists, therefore, for ways to prevent fires from occurring or growing sufficiently large to cause damage.SUMMARY OF THE DISCLOSURE[0003]Aspects include a system having a dryer, a temperature sensor positioned to measure the temperature inside the dryer or associated ductwork wherein the temperature sensor is coupled to an alarm system; an air flow sensor positio...
