That is a Crock Grill with the burner and grill missing. I had one back in the early 2000s. The hole is for where the burner plugs into the power supply/thermostat thing. Was actually a great cooking implement, and you should try to find the rest of the parts.
Edit : heres a link to an eBay listing of the model I had.
