Patent number: 5924857Abstract: An atmospheric burner is associated with a flame presence sensor and an electrical-discharge ignition device. It is fed via a flow rate control device. Both the ignition device and the flow rate control device are controlled by a microcontroller. A user interface enables the user to select the desired power by sending to the microcontroller a request for altering the flow rate and hence for altering the minimum power deliverable by the burner.Type: GrantFiled: August 27, 1996Date of Patent: July 20, 1999Assignee: Whirlpool CorporationInventors: Luca Frasnetti, Giampiero Santacatterina

Patent number: 5813320Abstract: Solenoid valves for controlling the gas flow to burners are controlled by an electronic microprocessor card by means of pulse-width modulated signals. The electronic card can receive signals from a timer to be set by the user, and from means by which the user selects the heat output of the burners. The first of said means to be operated by the user after setting the time makes the relative burner dependent on the timer. When the two data (time and heat output) have been set, the card extinguishes the flame of the dependent burner when the set time has expired.Type: GrantFiled: April 14, 1997Date of Patent: September 29, 1998Assignee: Whirlpool CorporationInventors: Luca Frasnetti, Gianpiero Santacatterina, Alessandro Distaso

Patent number: 5749388Abstract: The method provides for applying to the solenoid valve, during its movement of closure by the action of a spring, a voltage signal the purpose of which is to brake this closure movement. The circuit comprises a static switch connected between the coil of the solenoid valve and earth, and an intermediate tap between these two components from which a voltage signal is withdrawn and is transformed by a microcontroller into a control signal for the static switch, such as to apply the braking signal to the solenoid valve.Type: GrantFiled: August 27, 1996Date of Patent: May 12, 1998Assignee: Whirlpool Europe B.V.Inventors: Robert S.
