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.
Claims17
A cooking appliance configured to heat a cooking surface comprising:
- a controller for receiving a heat setting;
- a direct current (DC) powered heating element positioned in a housing wherein the controller and DC powered heating element are configured to connect to a source of DC electrical potential;
- wherein the cooking appliance is configured to connect to a source of DC electrical potential of at least 40 volts that powers other appliances;
- wherein activation of the DC powered heating element by the controller is configured to heat the cooking surface according to the heat setting;
- a solid state relay electrically connected to and controlled by the controller and wherein activation of the DC powered heating element by the controller is caused by switching the solid state relay on to deliver DC electrical potential from the source of DC electrical potential in order to generate heat in the cooking surface,
- wherein the cooking appliance excludes an alternating current (AC) powered heating element and excludes a combustion heating element, and wherein the cooking appliance is configured to be powered without a DC to alternating current (AC) conversion device positioned electrically between the source of DC electrical potential and the housing.
