Abstract

The utility model discloses a smokeless heating pit furnace. The smokeless heating pit furnace comprises an annular external furnace wall, an external furnace bottom, an annular internal flue cover plate, an annular internal furnace wall, an internal furnace bottom, a convex furnace platform for containing cookware, and a total smoke vent, wherein the annular external furnace wall, the annular internal furnace wall, the external furnace bottom and the annular internal flue cover plate form an annular internal flue; the convex furnace platform, the annular internal furnace wall and the internal furnace bottom form a hearth; an air inlet hole is formed in the convex furnace platform; a pluggable winter flue hole and a pluggable summer flue hole are formed at the upper part of the annular internal furnace wall; the winter flue hole and the summer flue hole are symmetrically arranged along the radial edge direction of the furnace center; the winter flue hole and the total smoke vent are symmetrically arranged along the radial edge direction of the furnace center; and the total smoke vent is connected with a discharge funnel. By the furnace, many shortcomings of the traditional pit furnace can be conquered; an effect of heating, boiling and cooking in winter, and boiling and cooking and canceling the heating function in summer can be achieved; and the smokeless heating pit furnace is especially suitable for rural areas in cold highland areas.

Description

A kind of smokeless heating pit furnace

Technical field

The utility model relates to a kind of stove and accessory, is specifically related to a kind of smokeless heating pit furnace.

Background technology

Particularly be at present the rural area of high and cold mountain area in some rural areas, extensively adopt the method heating that pit furnace (kitchen range) is set in hall winter, fuel used is mainly timber or dogstail.The tradition pit furnace does not arrange any safety protection facility, and during the comburant burning, sparks are flying in all directions, old man and the child who is trapped among surrounding easily damaged, but also can produce a large amount of dense smoke and the cigarette ash of houseful.In order to discharge fume, hall must open door and window, and the room temperature of hall just can not get improving like this, just only have the sole that heating effect is arranged, also causes the significant wastage of fuel wood.

Although northern country adopts a kind of ground fire coal or fuel wood warming stove of being placed on already, chimney leads to outdoor, can solve the contradiction of dense smoke and raising room temperature, but there is potential injury in the high-temperature furnace body that exposes all the time to the people, especially old man and child, and take no small location space.

The utility model content

Deficiency for above-mentioned existing pit furnace (kitchen range), the technical scheme that the utility model proposes not only can solve above-mentioned all problems, can also solve the inconvenience in summer of traditional pit furnace uses, the problem that function is too single reaches that can warming oneself winter heats up water and cooks, both can heat up water to cook and can also cancel the effect of heating function summer.

A kind of smokeless heating pit furnace described in the utility model comprises annular outer furnace wall, outer furnace bottom, and annular inner flue cover plate, annular internal protecting wall, interior furnace bottom is for the convex table that holds pan and total exhaust smoke hole.Annular outer furnace wall and annular internal protecting wall, outer furnace bottom, annular inner flue cover plate for sealing connect and compose annular inner flue, convex table and annular internal protecting wall, the interior furnace bottom formation burner hearth that is tightly connected.The convex table is provided with a fresh air inlet, but the top of annular internal protecting wall is provided with the floss hole in winter of a shutoff, and this floss hole and total exhaust smoke hole are symmetrical arranged by the direction radially along the line at stove center, and total exhaust smoke hole connects chimney.

Described interior furnace bottom is flat-bottom structure or arcuate bottom structure.

Described convex table is provided with a comburant and adds the hole, and this interpolation is furnished with shutoff device on the hole, and the convex table is made of cast iron.

Described annular inner flue cover plate is made by cast iron plate or steel plate, and this annular inner flue cover plate is provided with several ash removing openings, is furnished with shutoff device on ash removing opening.The described annular inner flue cover plate partial coverage of a side except ash removing opening outwardly has one deck heat proof material, as concrete or ceramic tile.

But the top of described annular internal protecting wall also is provided with the floss hole in summer of another shutoff, winter floss hole and summer floss hole be symmetrical arranged by the direction radially along the line at stove center, use floss hole and with floss hole shutoff in summer in winter when need heating function winter.Summer is not when needing heating function, uses floss hole and with floss hole shutoff in winter in summer.

The specific embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.

A kind of smokeless heating pit furnace described in the utility model comprises annular outer furnace wall 1, outer furnace bottom 2, and annular inner flue cover plate 3, annular internal protecting wall 4, interior furnace bottom 5 is for the convex table 6 that holds pan and total exhaust smoke hole 12.Annular outer furnace wall 1 and annular internal protecting wall 4, outer furnace bottom 2, the annular inner flue cover plate 3 looping inner flue 7 that is tightly connected, convex table 6 is tightly connected with annular internal protecting wall 4, interior furnace bottom 5 and consists of burner hearth 8.Convex table 6 is provided with a fresh air inlet 14, but the top of annular internal protecting wall 4 be provided with shutoff winter floss hole 10 and summer floss hole 11, winter floss hole 10 with summer floss hole 11 be symmetrical arranged by the direction radially along the line at stove center, winter, floss hole 10 was symmetrical arranged with the direction radially along the line of total exhaust smoke hole 12 by the stove center, and total exhaust smoke hole 12 connects chimneys.

When a kind of smokeless heating pit furnace described in the utility model is installed, dig out in advance the installation pit of sufficient size and lay the exit flue that moves towards outside the room on selected installation ground, the pit furnace level of smokelessly warming oneself is put into the hole, total exhaust smoke hole 12 is aimed at the exit flue that lays and is tightly connected, the room outer vent of the exit flue chimney that is tightly connected.But a regulating gate is set on exit flue, is used for regulating stack draught.
