Abstract

The utility model belongs to the field of stove manufacturing technology. The provided efficient domestic firewood gas stove includes an upper furnace jacket and a lower furnace body, wherein, the lower furnace body consists of a housing and a liner. The inner wall of the housing is provided with a thermal insulator with a rounded under-part and a subuliform upside. The interval between the thermal insulator and the liner is provided with a clearance which forms a secondary air duct; the adjustor of the band secondary air duct is arranged above a round orifice corresponding to an inlet opening; the upper outlet is movably provided with a helix flaming cap correspondingly; the inner wall is slantways arranged above a gib block, and the ring-shaped furnace jacket on the upside of stove is arranged inside a heating water jacket. The structure provided by the utility model makes the secondary air duct more convenient, the helix flaming cap which is movably arranged on the upside of the liner makes the flaming fires helical and firepower big; the surrounding burner port of the water jacket in the upside furnace jacket makes further usage of the origin of heat.

Description

Efficient family expenses firewood gas furnace

(1) technical field:

The utility model belongs to the cooking stove manufacturing technology, mainly proposes a kind of efficient family expenses firewood gas furnace.

(2) background technology:

Be used for rural households now, mainly, proposed multiple structural design in order to the cooking stove of burning straw, branch and sawdust.Its stove main body is made up of furnace shell and inner bag; Straw, branch and sawdust are inserted the inner bag from top and are burnt during use.And be provided with air intake and secondary air inlet structure, and one time air intake enters inner bag from the bottom, and secondary air enters inner bag top from the air channel between housing and the inner bag; The combustion wood stove of this structure has characteristics such as few with bavin, that firepower is big, flue dust is little.But still there are some local designs very unreasonable in its structural design, its performance is affected.

(3) summary of the invention:

The purpose of this utility model promptly is to propose a kind of efficient family expenses firewood gas furnace, by to the improvement of its structure with its practicality of further raising.

The utility model is finished the technical scheme that its invention task takes: stove has top boiler clothing and bottom body of heater; The bottom body of heater is made up of housing and inner bag, it is the thermal insulator of taper for circular, top that inner walls is provided with the bottom, have the gap between thermal insulator and the inner bag and constitute secondary air duct, the secondary air mouth that lower furnace is provided with connects housing and thermal insulator is communicated with secondary air duct; Ring-band shape secondary air adjuster is set, and it also is provided with the handle that makes its rotation between housing and thermal insulator; Set on the ring-band shape adjuster and the corresponding circular hole of secondary air mouth; The outlet of corresponding inner bag top is movably set with the spiral combustion ring cowling in the annular boiler clothing on stove top, and the spiral combustion ring cowling is the taper sheath of upper and lower opening, has the gib block of oblique setting on the taper sheath inwall; Be provided with the heating water jacket in the annular boiler clothing on stove top, water jacket has upper and lower two annular conduits that are interconnected, and two annular conduits are communicated with water tank by entering (going out) mouth of a river.

The structural design that the utility model proposes makes the control of secondary air convenient, and the spiral combustion ring cowling of its inner bag top movable setting can make combustion flame shape in the shape of a spiral, and firepower is bigger; Water jacket in the boiler clothing of top it can make thermal source further be utilized around the port setting.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is a ring-band shape secondary air controller structure schematic diagram.

Accompanying drawing 3 is a spiral combustion ring cowling structural representation.

Accompanying drawing 4 is Fig. 3 A-A profile.

Among the figure, 1-water tank, 2-water inlet pipe and water outlet pipe, 3-heat-insulation layer, 4-spiral combustion ring cowling, 5-top boiler clothing, 6-chimney, 7-water jacket, 8-secondary air outlet, 9-thermal insulator, 10-fire grate, 11-secondary air mouth, 12-handle, 13-movable ash bucket, 14-air inlet, 15-inner bag, 16-ring-band shape adjuster, 17-circular hole, 18-gib block.

(5) specific embodiment:

The embodiment that provides is in conjunction with the accompanying drawings further specified its structure:

As shown in Figure 1, stove is made up of top boiler clothing 5 and bottom body of heater; Top boiler clothing 5 is a circulus, is made of double layer of metal housing and middle heat-insulation layer 3, and top has bell.The base circle hole is communicated with the inner bag of bottom body of heater.The bottom body of heater has housing and inner bag 15, inner walls is provided with the thermal insulator 9 of moulding, thermal insulator 9 bottoms are pyramidal structure for circular, top, between thermal insulator 9 and inner bag 15, have the gap and constitute secondary air duct, lower furnace sets the secondary air mouth 11 of several circle distribution, and secondary air mouth 11 connects housing and thermal insulator 9 is communicated with secondary air duct; 15 top loop weeks of inner bag set secondary exhaust vent 8, make secondary air enter inner bag along it, play with an air intake to cooperate combustion-supporting effect.Be provided with ring-band shape adjuster 16, in order to control and adjusting secondary air.Ring-band shape adjuster 16 is also rotatable between housing and thermal insulator 9, set circular hole 17 at ring-band shape adjuster 16, the secondary air mouth 11 that sets on its number and the body of heater is consistent, spur the handle 12 on the ring-band shape adjuster 16 thus, adjuster rotates, circular hole 17 on it is corresponding mutually with secondary air mouth 11, be that the secondary air mouth is opened, circular hole 17 on the adjuster is not corresponding with secondary air mouth 11, being about to secondary air mouth 11 closes, regulate the size of its counterpart, promptly regulate the adjustable size joint secondary air amount that the secondary air mouth is opened.One time air inlet 14 is arranged on lower furnace, and it directly is communicated with inner bag 15, and air intake is provided one time from the inner bag bottom.The inner bag upper opening is joined with the corresponding kiss of top boiler clothing bottom opening, and movable spiral combustion ring cowling 4 is set, insert straw etc. in the inner bag and after lighting, spiral combustion ring cowling 4 is placed exit position, inner bag 15 top, spiral combustion ring cowling 4 is the taper sheath of upper and lower opening, have many on the inwall and be spaced and tilting gib block 18, so that flame shape in the shape of a spiral plays the effect that strengthens firepower.The fire grate activity is shelved on the inner bag 15, and promptly the inwall of inner bag 15 is provided with annular boss, in order to the plate-like fire grate is born.Consider straw, branch and sawdust size length difference, several annular boss that height differs are set on the inner bag inwall, think according to using needs to adjust the height of fire grate.Bottom of furnace body has circular ash hole, and the movable ash bucket 13 of relative set, and ash bucket is a drawer structure, is positioned at the pull groove that bottom of furnace body sets, but pull takes out.Be provided with water jacket 7 in the boiler clothing of top, water jacket has upper and lower two ring pipes and upper and lower ring pipe is the structure that communicates, and two ring pipes are communicated with body of heater water tank 1 outward by advancing (going out) water pipe 2.
