Abstract
A DC powered cooking appliance which uses an induction or a resistance based DC heating element and excludes AC powered heating elements and preferably does not rely on directly connected combustion powered heating elements. Some embodiments include wattage of 1500 watts or less, voltages of 40 or 48 volts or more and are installed on a boat, van, rv or bus such that an inverter of that boat, van, rv or bus is not electrically connected to the cooking appliance.
Claims19
A cooking appliance configured to heat a cooking surface comprising:
- a controller;
- a non-mechanical switch electrically connected to and controlled by the controller;
- a direct current (DC) powered heating element electrically connected to the non-mechanical switch;
- a source of DC electrical potential;
- wherein activation of the DC powered heating element by the controller is caused by switching the non-mechanical to control delivery of DC electrical potential from the source of DC electrical potential to the DC powered heating element to thereby control heating of the cooking surface which is configured to be located adjacent the DC powered heating element;
- wherein the cooking appliance excludes an alternating current (AC) powered heating element and excludes a combustion heating element and the cooking appliance further excludes an inverter positioned in a housing of the cooking appliance and excludes an AC to DC converter positioned in the housing.
A cooking appliance configured to heat a cooking surface comprising:
- a pulse width modulation (PWM) controller;
- a non-mechanical switch electrically connected to and controlled by the PWM controller;
- a direct current (DC) powered heating element electrically connected to the non-mechanical switch;
- a source of DC electrical potential;
- wherein activation of the DC powered heating element by the controller is caused by switching the non-mechanical switch to deliver DC electrical potential from the source of DC electrical potential to the DC powered heating element to thereby heat the cooking surface which is configured to be located adjacent the DC powered heating element;
- wherein switching the non-mechanical switch is accomplished while the source of DC electrical potential delivers a voltage of at least 40 volts.
