Description

FIELD OF THE INVENTION

The present disclosure relates to portable cooking devices.

BACKGROUND OF THE INVENTION

Portable cooking appliances have grown in popularity in recent years. There are a number of types of portable cooking appliances commonly used: gas cooking appliances and electric cooking appliances, and solid fuel cooking appliances. Gas cooking appliances employ at least one gas burner to cook food that is supported on a grate above the burner(s). The fuel source for gas grills is typically liquid propane or natural gas. Electric cooking appliances can utilize an electrical heating element integrated into the cooking surface. A power supply is connected to the cooking appliance to provide power to the heating element. Regardless of the type, the cooking appliance has a cooking chamber that includes a cover and a cooking surface. By movement of the cover, the cooking chamber is movable between an open position and a closed position. The cooking chamber may be in the closed position when the food is being cooked by the cooking appliance. Preferably, the cover is in the closed position when the cooking appliance is not in use, and instead is stored between uses.
