Description

Improved domestic heating stove

Technical field: the utility model relates to the furnace that uses in a kind of family, particularly improved domestic heating stove.

Background technology: at present, the vast rural area of northern China uses the phenomenon of coal stove for heating still more general, traditional coal stove is simple in structure, the point ember both can have been heated up water in burner hearth, cook, can warm oneself again, and traditional furnace also just holds a circle water jacket simply around burner hearth, the heat that utilizes coal burning generation in the burner hearth is with the water heating service in the water jacket, the opening of chimney is set directly on the hearth wall, its weak point is outlet one side that the flame of coal burning often directly is partial to chimney, when people when cooking, just there is the uneven problem of heating in flame to the cooker bottom, a large amount of heat energy have have directly scattered and disappeared along chimney, and heat energy not only loses greatly, and utilization rate is low.

Summary of the invention: the purpose of this utility model is to provide a kind of improved domestic heating stove, and the flame that can solve traditional furnace burning generation effectively reduces heat-energy losses to the uneven problem of cooker bottom heating, raising heat energy utilization rate.

The purpose of this utility model is achieved in that a kind of improved domestic heating stove, it comprises the body of heater that the stove leg is installed, its bottom-open, the upper of furnace body both sides are respectively arranged with exhaust smoke hole, on the body of heater in its outside flue is being set, the inside of body of heater space from outside to inside is being provided with annular outer water jacket and inner water sleeve, form columnar external flue between outer water jacket and the body of heater, outer water jacket and inner water sleeve are the height layout respectively and are interconnected by water channel, water channel is separated into two semicylindrical inner flues with the space between outer water jacket and the inner water sleeve, in, the bottom of external flue is communicated with, inner water sleeve is around forming burner hearth, the bottom of outer water jacket is provided with water inlet pipe, its top is provided with outlet pipe, the bottom of burner hearth is provided with fire grate, is being equipped with annular capping between the bottom of wall extension and body of heater under the outside of inner water sleeve bottom, and the top of outer water jacket and the top seal of body of heater link together.

When the utility model uses, the inlet tube and outlet tube and the room heater pipeline that will be arranged on earlier on the outer water jacket connect, on fire grate, put coal well and light, on table, place cooker or bell is built, the flame of coal burning comes out then by the inner flue between the inside and outside water jacket in burner hearth earlier, bottom through outer water jacket enters the flue that is arranged on the outside, body of heater upper end along the external flue between outer water jacket and the body of heater again, discharges from chimney.Continuous with the water heat cycles in the inside and outside water jacket in the process that flame weaves, reduced the loss of heat energy to greatest extent, improved the heat energy utilization rate, because flame is not directly to be partial to flue, the problem that does not have flame deflection, therefore flame distribution is even, can accomplish even heating to the cooker bottom.The utility model is simple in structure, rationally, is easy to make, and cost is low, is easy to promote.
