Abstract

An high-efficiency energy-saving cooking range which is characterized in that: a furnace door disposed on the top part of the furnish shell is a feeding inlet, a furnace pipe is composed of inner pipe and outer pipe, the inner pipe wall is provided with wind inlet, and the diameter of the outer pipe is larger than the inner pipe, and the inner and outer pipe are sheathed together in the furnace shell with the same center, and the space between the inner pipe and outer pipe is a wind inlet. A horn-shaped furnace roof is disposed on the top end of the inner pipe, and the vertical distance between the top end of furnace roof and the boiler is a smoke exhausted slit, and the distance between the outer edge of the furnace roof and furnace shell wall is a smoke exhausted channel. The cooking range can be used with a plurality of fuels, such as firewood, sawdust, coal, wasted oil, wasted plastics and so on, with simple structure, high heat efficiency and low costs, can be applicable for the country.

Description

A kind of high efficiency energy saving stove

(1) technical field:

The utility model relates to kitchen range, specifically a kind of high efficiency energy saving stove.

(2) background technology:

At present, faggot kitchen range or the coal stove that use in vast rural area have multiple, mostly by furnace shell, fire door, air intake ash disposal mouth, compositions such as flue, furnace bottom, chimney, these cooking stoves all rose in people's life or played an important role, but still had not enough place, and it is single to have plenty of the fuel of use, the burning coal that burns faggot is not all right, and that burns coal can not burn faggot again; The heat energy utilization rate of having plenty of fuel is low, energy waste is big; Has plenty of indoor environment of flue dust, smoke pollution kitchen or the like.

(3) utility model content:

The purpose of this utility model will disclose and a kind ofly use fuel face width, thermal efficiency height, fuel saving, do not pollute the kitchen indoor environment, simple in structure, be convenient to make, make things convenient for the shift position, particularly be fit to the high efficiency energy saving stove that use in vast rural area.

This is novel mainly by furnace shell, fire door and door opening, air intake ash disposal mouth, flue, furnace bottom, fixedly plate rail, furnace roof, smokejack, chimney are formed, described furnace shell, fire door and door opening, furnace bottom, stove chimney and prior art are basic identical, different is: charging aperture fire door and door opening are arranged on furnace shell top, with the furnace shell inwall of base, fire door hole sustained height on, be fixed with the annular fixed disk frame that central authorities are processed with the diameter circular hole identical with the inner bag internal diameter.Flue is made up of inner bag and outer courage, outer courage diameter and length are all greater than inner bag, overlapping of inside and outside courage concentric is packed in annular fixed disk frame below, the central circular hole of the top of inner bag and annular fixed disk frame connects, above the annular fixed disk frame, be provided with one on the inner bag top ports and highly be lower than the furnace shell top and have the horn-like furnace roof of breach at the door opening place.

Described inner bag, its wall are provided with 36～42 circular fresh air inlets, and the distance between the inside and outside courage is 15～20mm, and the space between them is an air inlet duct.

Described horn-like furnace roof, its vertical section are a right angle triangle, and the angle of the hypotenuse and the straight horizontal arm of angle is 45～60 °, vertical straight arm of angle top to the pot body vertical range be smoke evacuation seam, the vertical straight arm of angle is a smokejack to the distance 20～40mm of furnace shell wall.

Smokejack exports on the furnace shell wall that is arranged on corresponding of fire door hole and chimney is communicated with, and chimney stretches out outside the roof, kitchen.

During this novel use, fuel is put into from the fire door hole, after lighting, closes fire door, and air enters from air intake ash disposal mouth, enters furnace internal-lining through air inlet duct and fresh air inlet and participates in burning, and flue gas enters smokejack from the smoke evacuation seam, discharges outdoor from smokejack through chimney again.This cooking stove:

(1), use the fuel face width, can be faggot, coal cinder, coal briquette, husk, wooden chaff, used oil, waste plastics etc.;

(2), oxygen is sufficient, burning is complete, the thermal efficiency is high, the fuel thermal energy utilization rate can reach more than 80%;

(3), because pot body and top, furnace wall seal basically, and smog can not leak into indoor, kitchen environment can be not contaminated;

(4), simple in structure, easy to manufacture, cost is low, changeable, conveniently moving, very be fit to vast rural area and use.

(4) description of drawings:

Fig. 1 is a vertical profile structural representation of the present utility model.

(5) specific embodiment:

The utility model furnace shell (1) is made with square or circular metal bucket, and fire door hole (3) are offered downwards from furnace shell (1) top.With the same axis of fire door hole (3) on, upwards offer air intake ash disposal mouth (13) from the bottom of furnace shell (1), with the inwall of the furnace shell (1) of the sustained height on the base of fire door hole (3) on, welding central authorities are processed with the annular fixed disk frame (2) of the diameter circular hole the same with flue (9) interior diameter, inner bag (9) is made by galvanized pipe, on inner bag (9) wall 42 circular fresh air inlets are set, outer courage (10) is made by cast iron pipe, outer courage (10) diameter is greater than inner bag (9) diameter 40mm, inside and outside courage (9,10) the concentric suit the below that installs annular fixed disk frame (2), the central circular hole and the inner bag top ports of annular fixed disk frame (2) are connected, and furnace bottom (12) places in inner bag (9) lower port.Top in annular fixed disk frame (2), with refractory material from inner bag (9) upper port edge, make progress sideling, outwards expand, being piled into vertical section is the horn-like furnace roof (8) of right angled triangle, and high-end distance pot body (6) the 15mm distance of horn-like furnace roof (8) is a smoke evacuation seam (5), the outer rim of horn-like furnace roof (8) and furnace shell (1) 40mm distance, be smokejack (4), with the obverse furnace shell of door opening (3) (1) wall on offer smokejack (4) outlet, be communicated with chimney (7).
