Description

Energy-efficient swingfire burner hearth

Technical field

The utility model relates to cooking stove, specifically is meant the chamber structure of cooking stove.

Background technology

The burner hearth of prior art mostly is the straight barrel type structure greatly, and energy resource consumption is big, and the heat energy utilization rate has only 20 tens percent to percent usually, demands urgently improving.

The utility model content

The technical problems to be solved in the utility model is that the defective at prior art exists proposes a kind of energy-efficient swingfire burner hearth, its thermal efficiency height, fuel savings are remarkable, simple in structure, dependable performance, wide accommodation can be used as the burner hearth of stoves such as fire coal, combustion gas, fuel oil, kitchen range.

The technical solution of the utility model is, it is the burner hearth body of heating chamber that described energy-efficient swingfire burner hearth has top, and its design feature is that described heating chamber bottom surface is provided with the combustion chamber for the higher inclined-plane of lower periphery, middle part below these heating chamber bottom surface central authorities; The upper port periphery is equipped with interior fire-collection ring in described combustion chamber, and circle body of fire-collection ring is provided with one section downward opening breach in this; Fire-collection ring outside the periphery of fire-collection ring is equipped with in described, the circle body of this outer fire-collection ring are provided with a plurality of downward opening breach; In described heating chamber, heat build-up groove in forming between outer fire-collection ring and the interior fire-collection ring forms outer heat build-up groove between outer fire-collection ring and the heating chamber inwall.

Below the utility model made further specify.

Referring to Fig. 1, it is the burner hearth body 2 of heating chamber 1 that described energy-efficient swingfire burner hearth has top, and its design feature is that described heating chamber bottom surface 3 is provided with combustion chamber 4 for the higher inclined-plane of lower periphery, middle part below these heating chamber bottom surface 3 central authorities; Fire-collection ring 5 in described combustion chamber 4 upper port peripheries are equipped with; As Fig. 2, circle body of fire-collection ring 5 is provided with one section downward opening breach 6 in this; Fire-collection ring 7 outside the periphery of fire-collection ring 5 is equipped with in described, the circle body of this outer fire-collection ring 7 are provided with a plurality of downward opening breach 8; In described heating chamber 1, heat build-up groove 9 in forming between outer fire-collection ring 7 and the interior fire-collection ring 5 forms outer heat build-up groove 10 between outer fire-collection ring 7 and heating chamber 1 inwall.

Further, as Fig. 1, in described heating chamber 1, the height of fire-collection ring 5 in the height of outer fire-collection ring 7 can being designed to be higher than and be lower than the height of heating chamber 1 upper port.

Design principle of the present utility model is, during actual the use, and the exhaust opening of the breach 6 corresponding cooking stoves of interior fire-collection ring 5; Bowl is placed on the burner hearth body 2, the flame that combustion chamber 4 produces some because of the compressing in the bottom of a pan breach 6 by interior fire-collection ring 5 enter in the heat build-up groove 9, each breach 8 by outer fire-collection ring 7 enters in the outer heat build-up groove 10 again, make whole flame in burner hearth, be three circle rotary combustions thus, heat energy is fully used, its thermal efficiency can reach 60%, can save energy 40% than burner hearth commonly used.

In the described combustion chamber 4 oil burner or gas burner can be installed, or as the fired coal combustion chamber.

As known from the above, the utility model is a kind of energy-efficient swingfire burner hearth, its thermal efficiency height, remarkable, simple in structure, the dependable performance of fuel savings, and wide accommodation can be used as the burner hearth of stoves such as fire coal, combustion gas, fuel oil, kitchen range.
