Summary of the invention is at above-mentioned deficiency, and the utility model is exactly that a kind of steamer that possesses two kinds of energy saving ways simultaneously will be provided.

The steamer that the utility model provides, the pot body that dress water is arranged, the end of pot body, be provided with recessed flame-holding chamber annular, upwards dark, a chuck arranged in that said pot is external, have at the bottom of the chuck and stretch into the dark recessed interior annular wall of pot body bottom annular, the height of annular wall is not as good as dark recessed top, and with interior no diapire, air vent is arranged at chuck top in the interior circle annular wall in the chuck bottom.

The steamer that the utility model provides is designed to the recessed deeply of annular with the bottom of a pan, has kept surface, the bottom of a pan to enlarge heat exchange area and has increased the characteristics that heat transfer efficiency is increased.Not only pot external add chuck (the known notion of so-called chuck be enclosed within pot external but also at the boiler port two layers of walls formed sheaf space that is tightly connected), and at the bottom of the chuck, be provided with annular wall, this annular wall does not contact with dark concave crown on the dark recessed position of annular and the wall top in the bottom of a pan, simultaneously the interior circle annular wall with interior do not had chuck at the bottom of.When placing this steamer on the stove, heat enters chuck from the middle position that chuck does not have the end, is separated by and forms tortuous heat (cigarette) gas passage through annular wall, discharges from the air-vent on chuck top at last.Compared with prior art, the utility model not only the bottom of a pan has increased heat exchange area, also increases heat exchanger time and has designed tortuous passage for heat (cigarette) gas is detained more, and the thermal efficiency is improved greatly.

The steamer that the utility model provides also is provided with overdo wall or upwards dark recessed appearance fire hole honeycomb arrangement, that protrude at the bottom of a pan annular flame-holding chamber downwards with interior, with the heat exchange area in the further increase the bottom of a pan.

The steamer that the utility model provides, chuck outer casing bottom have the fiery tube that is subjected to of downward stretching, extension, in order to cover on the stove fire, make ingle heat all enter the steamer chuck.
