US Patent:

51738430, Dec 22, 1992

Filed:

Sep 11, 1990

Appl. No.:

7/580747

Inventors:

Mitchell R. Rowlette - Berea KY
Kenneth L. Hayden - Bardstown KY
Gary J. Steffes - Monroe MI

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H05K 118

US Classification:

361406

Abstract:

A fan control board and circuit having a central low voltage wiring center as well as a safety interlock for electric heater in which the interlock uses diodes to ensure proper fan operation in the event of miswiring of the heater sequencers. Another feature of the invention is a quick connect for a time delay of the circuit which permits easy insertion and removal thereof for replacement and/or cleaning.

International Classification:

US Classification:

318471

Abstract:

A fan control board having a central low voltage wiring center as well as a safety interlock for electric heaters. The interlock uses diodes to insure proper fan operation in the event of miswiring of the heater sequencers. Another feature is a quick connect for the time delay relay which permits easy insertion and removal thereof for replacement and/or cleaning. Diode circuits are provided in both the circuit to normally power the fan motor as well as in the circuit to power the PTC resistor which closes the fan motor circuit with the circuit which powers the PTC resistor also being connected across the fan motor circuit to provided rectified power to the fan circuit and permit the fan motor to turn on concurrently with the application of power to the PTC resistor to prevent the heater from being turned on prior to the fan. Circuitry to control each of multiple furnace heater elements is also applied via rectification circuitry to the fan motor circuitry to cause operation of the fan motor regardless of the order of operation of the heater elements of a furnace. There is also provided a quick connect and time delay relay design to allow easy insertion and removal of the relay for cleaning and/or replacement by having three spaced contacts on the housing surface of the relay with the quick connect having resilient opposed C-shaped terminal for frictionally locking one of the relay contacts therein and a pair of terminals at opposite ends thereof, at least one being resilient for contacting the other contacts on the housing.

Texas Instruments Incorporated - Dallas TX

International Classification:

H01H 3704
H01H 3752

US Classification:

337380

Abstract:

A high limit thermostat for gas furnace applications is shown having a molded base plate and an elongated housing formed integrally with the base plate which mounts a thermostat at a free end of the housing in order to be positioned within an air stream of a heat exchanger to sense temperature conditions of the air stream. An extended version is shown in which one end of a pair of elongated terminals are received in slots formed in the housing with the thermostat mounted on the opposites ends of the elongated terminals.
