Grill device with a safety unit for ensuring electrical disconnection when two grill units are separated

A grill device comprising:

• a horizontal lower grill unit having a left side;
• a horizontal upper grill unit superposed on said lower grill unit to form a closed position with said lower grill unit, and having a first side and a bottom surface;
• a cooking member on said bottom surface of said upper grill unit;
• an insulated terminal-mounting seat on said left side and having a left side face;
• a ground terminal hole extending inwardly relative to said terminal-mounting seat from said left side face;
• first and second terminals extending outwardly and in parallel from said left side face of said terminal-mounting seat and being electrically coupled with said cooking member;
• a spring-biased blocking plate mounted on said left side face of said terminal-mounting seat and covering a portion of said ground terminal hole in said terminal-mounting seat to block access to said ground terminal hole when said upper grill unit is moved away from said lower grill unit;
• and
• a push plate with a through hole on said left side of said lower grill unit to push said blocking plate away from said ground terminal hole in said terminal-mounting seat when said upper grill unit is disposed at said closed position, thereby establishing spatial communication between said through hole in said push plate and said ground terminal hole in said terminal-mounting seat.
