Appliance with electronically-controlled gas flow to burners

A cooking hob, comprising:

• a first burner assembly;
• a first gas path extending from an inlet to the first burner assembly;
• a first fuel injector positioned within the first gas path and including a first solenoid valve that defines an open condition and a closed condition;
• and
• a controller electronically coupled with the first fuel injector for controlling a flow of gas through the first gas path to the first heating element by executing a series of pulses of the first fuel injector at a first rate corresponding to a desired gas flow to the first heating element, each of said pulses including moving the first solenoid valve from the closed condition to the open condition and back to the closed condition.

A cooking hob, comprising:

• a first gas-burning heating element;
• a first gas path extending from an inlet to the first heating element;
• a first solenoid valve positioned within the first gas path;
• a second gas path extending from the inlet, upstream of the first solenoid valve, to the first heating element and supplying a base gas flow to the first heating element;
• a first mechanically-actuated valve coupled with the second gas path and positionable in a closed position and an open position, wherein, when in the closed position, the first mechanical valve cuts off the base flow of gas through the second gas path to the first heating element and, when in the open position, the first mechinical valve permits the base flow of gas through the second gas path to the first heating element;
• and
• a controller electronically coupled with the first solenoid valve for controlling a supplemental flow of gas through the first gas path to the first heating element, the supplemental gas flow combining with the base gas flow to achieve a total gas flow, the controller controlling the supplemental flow to adjust the total gas flow by pulsing the first solenoid valve at a first rate corresponding to a desired rate of the total gas flow to the first heating element.
