Multi-zone griddle and grill

A multi-zone griddle comprising:

• an upper continuous layer having a predetermined length;
• a first lower layer having a predetermined length that is less than the predetermined length of the upper continuous layer and a second lower layer having a predetermined length that is less than the predetermined length of the upper continuous layer, said first lower layer and said second lower layer being spaced a predetermined distance relative to the upper continuous layer;
• the predetermined length of said first lower layer and the predetermined length of the second lower layer being substantially equal to the predetermined length of the upper continuous layer of metal with a space being formed between the first lower layer and the second lower layer;
• and
• a first serpentine passageway and a second serpentine passageway disposed between the upper continuous layer and the first lower layer and the second lower layer;
• wherein said first serpentine passageway and said second serpentine passageway are formed as two pieces to make a thermal break between the first serpentine passageway and the second serpentine passageway and the first lower layer and the second lower layer are formed as two pieces to make a thermal break between the first lower layer and the second lower layer and wherein supplying a heated fluid of a first predetermined temperature to said first serpentine passageway and supplying a heated fluid of a second predetermined temperature to said second serpentine passageway permits a first portion of the upper continuous layer to be maintained at a first temperature and a second portion of said upper continuous layer to be maintained at a second temperature.

A multi-zone griddle comprising:

• an upper continuous layer having a predetermined length and width;
• a lower layer having a predetermined length and width that is substantially equal to the predetermined length and width of the upper continuous layer, said lower layer being spaced a predetermined distance relative to the upper continuous layer;
• said lower layer including a slit being formed along at least one of said predetermined length and width for forming a thermal break between a first side of the lower layer and a second side of the lower layer;
• and
• at least one serpentine passageway disposed between the upper continuous layer and at least one of the first side and second side of the lower layer;
• wherein said thermal break formed by the slit in the lower layer and said at least one serpentine passageway supplied with a heated fluid of a predetermined temperature permits a first portion of the upper continuous layer to be maintained at a first temperature and a second portion of said upper continuous layer to be maintained at a second temperature.
