Abstract

The utility model relates to a screw-type domestic heating stove which is composed of an ash bucket (1), a chassis (2), a stove core (4), a stove wall (5), a stove opening (6), a flue (7), a stove cover (8), and a heat-insulating material (12). The utility model is characterized in that the periphery of the stove core (4) is coiled with a heat exchange tube (11). A secondary vent tube (3) is arranged at the point of the stove opening, and the other end of the secondary vent tube (3) is communicated with the ash bucket (1). A burning return chamber is arranged on the stove opening. The heat exchange tube is heated again in the burning return chamber, which realizes that the coal can be burned sufficiently through the secondary oxygenation. The heat at the points of a stove hearth and the stove opening is utilized fully, and the speed of the heating cycle is high. When required, the heating stove can be provided with a plurality of groups of radiators. The utility model has the advantages of little investment, easy production, and coal saving effect. Besides, the utility model is a good product for cooking and heating.

Description

Spiral domestic heating stove

Spiral domestic heating stove belongs to the domestic stove class.

Existing China domestic stove is of a great variety, pattern is different, but the kind of domestic heating stove is few, and the domestic heating stove is an indigenous heating stove now, generally all be that cover one water adds cover on combustion chamber, because welding is many, water resistance is big, putting one at the fire door place has secondary heating furnace, and the shortcoming of this heating stove is: the heating meeting is influenced when cooking, the speed of cooking is slow, coal can not fully burn, and is very inconvenient during stoking, the many groups of band radiator difficulty.

The purpose of this utility model is to design a kind of, and coal is fully burnt, and can be with the heating of many group radiators, does not influence the energy-saving heating stove of cooking again.

This stove and accessory can be on the basis of common stove and accessory or is directly produced and realize.The utility model is real like this: no matter be single combustion chamber or many combustion chambers, all be upwards to coil heat exchanger tube by the middle spiral of stove in the periphery of combustion chamber, up to the fire door place, on fire door, enclose heat exchanger tube around fire door dish 1--4 again, can put the metallic plate of burn-oning above the heat exchanger tube, also can put the reinforcement of burn-oning, at the fire door place according to what of combustion chamber, adorn 1--5 secondary ventiduct, the air inlet of secondary ventiduct is trembled connection with ash above ash is trembled, place one on the fire door and return the burning ring, return and burn ring to be shaped as the uncovered end of end garden with holes barrel-shaped, opening end is placed on the fire door, with return burn that annular distance matches burn lid for returning, return and burn that to cover be a garden shape metallic plate, return to burn to encircle and return to burn to cover to constitute and return the burning chamber, return the indoor outlet that has heat exchanger tube of burning.

The utility model is compared with common stove and accessory, has that to burn coal abundant, and the heat at breast and fire door place can be fully utilized, and thermal cycle soon, does not influence the interpolation coal, is difficult for flame-outly, can take up the advantages such as radiators of organizing when needing more.

Be elaborated below in conjunction with accompanying drawing:

Accompanying drawing is the cutaway view of spiral domestic heating stove.

Among the figure, 1 for ash tremble, 2 for the chassis, 4 for combustion chamber, 5 for the furnace wall, 6 for fire door, 7 for flue, 8 for bell, 12 for insulation material, it more than is the basic building block of common stove and accessory, this utility model is to have increased heat exchanger tube 11 on common stove and accessory basis, 1--5 secondary ventiduct 3 and one return and burn the chamber.Heat exchanger tube 11 is enclosed within on the combustion chamber 4, and at the square position 1--4 of fire door place circle, also can be on the good heat exchanger tube of dish spot welding one metallic plate 13, or the some reinforcement of burn-oning.Secondary ventiduct 3, one ends and ash are trembled connection, and an end places the fire door place.Return burn the chamber be an end on fire door, with holes barrel-shaped of an end return burn ring and with return returning of burning that annular distance matches and burn lid and constitute, heat exchanger tube 11 and secondary ventiduct 3 are placed in to return and burn indoorly, return and burn the outlet that there is heat exchanger tube 11 chamber.
