Patent number: 7013577Abstract: A clothes dryer has a test button for testing the fire suppression system of the dryer. The test button is connected to the temperature sensor of the fire suppression system such that when the test button is actuated it presents a signal, such as by shorting the two leads of the temperature sensor together, to simulate the condition of the temperature sensor sensing a high temperature. This triggers the control circuit of the fire suppression system to turn on a water valve to activate the sprinkler system. The fire suppression system is then reset by actuating a reset button.Type: GrantFiled: June 14, 2004Date of Patent: March 21, 2006Assignee: Alliance Laundry Systems LLCInventor: Andrew F. Kegler

Patent number: 6971186Abstract: A filter assembly for collecting lint in use with a dryer having an interior compartment. The filter assembly includes a control unit, an input air pathway in communication with the interior compartment, an exhaust, and a micro-filter. The input air pathway carries air and lint from the interior compartment through the micro-filter into the exhaust. The filter assembly includes a first and second air flow sensor in the interior compartment for determining the change of air flow between the input air pathway and exhaust. The control unit is in communication with the first and second air flow sensors and an alarm. The control unit triggers the alarm when the air flow sensors detect a restricted pattern of air flow, thereby signaling a build-up of lint in the filter.Type: GrantFiled: February 11, 2004Date of Patent: December 6, 2005Inventors: TJ Chin, Patricia Farrow

Publication number: 20040187343Abstract: A safety system is for the clothes dryer. The safety system determines whether the flow of exhaust air is above a pre-set level, and causes an interruption of electrical power to the clothes dryer if there is not. The invention provides for more efficient drying of clothes and reduces risk of fires. The system may also include an interruption of electrical power for other malfunctions of clothes dryer. A non-restricting cover plate is adapted for use with a clothes dryer having a removable lint screen and an exhaust pipe. The cover plate allows air and lint into the exhaust pipe and prevent clothes from entering the exhaust pipe.Type: ApplicationFiled: January 12, 2004Publication date: September 30, 2004Inventor: Bart Donald Beaumont

Patent number: 6725570Abstract: A clothes dryer having a fire protection system. The clothes dryer chamber has an inlet which receives drying air and an exhaust for removing moisture laden air. The temperature within the drying chamber is monitored, and a determination is made from the dryer electronic controller whether or not a fire exists in the tumbler. The fire detection conditions are based on determining whether a certain temperature rise exists within the tumbler when the drying air ceases. The fire suppression system when activated will inject a fire suppressing substance into the tumbler for suppressing the fire.Type: GrantFiled: November 29, 2002Date of Patent: April 27, 2004Assignee: American Dryer CorporationInventors: Michael W. Confoey, Dennis Slutsky

Patent number: 6715216Abstract: A clothes dryer is provided with a fire detection and suppression system which releases a fire suppressing substance into the dryer chamber upon detection of a fire condition. The fire detection and suppression system includes, a controller, at least one temperature detector which is in communication with the controller and sends a signal to the controller when a temperature set point has been reached and/or exceeded, a source of fire suppressing substance (preferably water) which is delivered to the chamber over a pathway; and a valve in the pathway controlled by the controller. The controller opens the valve when a fire condition is detected, and closes the valve after a time sufficient to introduce a predetermined volume of the fire suppressing substance has passed.Type: GrantFiled: July 11, 2003Date of Patent: April 6, 2004Assignee: Cissell Manufacturing CompanyInventors: Naom Salameh, Stanley T. Wheeler

Patent number: 6655047Abstract: A fire arrester for use with a clothes dryer includes a fire detector at the dryer vent to detect fires starting in the dryer and provides an electrical power disconnect means to break the flow of electrical power being supplied to operate the dryer. Optionally, the signal is applied to release an extinguishing agent or fire suppressant into the interior of the dryer just prior to shutting off the dryer blower. The output signal from the fire detector can also be used to provide various alarms, including local visual and/or alarms, as well as a remote alarm, which can be accomplished by sending a signal to a remote monitoring facility such as a home intrusion service or to a local fire department. Optionally, the activation of any of the alarm signals, and/or the activation of any of the features or functions of the fire arrester can be accomplished by using wireless communications.Type: GrantFiled: April 23, 2002Date of Patent: December 2, 2003Inventor: Andrew C Miller, II

Patent number: 5431179Abstract: A wafer drying apparatus incorporated in a semiconductor wafer cleaning system includes a bath for storing IPA. A heater for generating an IPA vapor is arranged on the bath. The bath is surrounded by a housing. The housing has opening portions at three positions. The opening portions are opened/closed by shutters. A sensor for detecting a fire and a nozzle for discharging CO.sub.2 gas into the bath are arranged around the bath. A plurality of wafers are held by a chuck of a convey robot and are conveyed from the outside of the housing into the housing via the opening portions. When a fire is detected by the sensor, the chuck immediately retreats from the housing, and the shutters are closed. Signals for closing the shutters are transmitted to shutter drive sources again 10 seconds after the fire is detected, and discharging of CO.sub.2 gas is started 20 seconds after the fire is detected.Type: GrantFiled: February 16, 1994Date of Patent: July 11, 1995Assignees: Tokyo Electron Limited, Tokyo Electron Kyushu LimitedInventors: Takanori Miyazaki, Kazuhiko Kobayashi, Yuuji Kamikawa, Chihaya Tashima
