The bottom view in your image highlights its distinctive central hollow tube, which allows heat and steam to circulate efficiently for even cooking.
...consists of a bottom water reservoir and a top cooking insert with a central chimney.
It's a Dragão, but it's aluminium, not stainless steel. Also the
distinctive central hollow tube is very different to the one in the photo in the link posted, which is sealed at the end. Mine is open ended to allow hot gases to flow up and through.
Also there is no bottom water reservoir.
Mine is a stove top oven!
