Description

Family expenses automatic stoking heating stove

The utility model relates to a kind of domestic heating stove, is specifically related to the domestic heating stove of energy automatic stoking.

At present, all there is a common deficiency in various domestic heating stoves (or claiming native heating boiler), promptly can not move continuously automatically, need people's coal at any time, hear at daytime working and night and fall asleep unserviced the time, the just necessary smouldering fire of stove, otherwise continuous burning goes down, will extinguish because of fuel burns, like this, cause the heating temperature instability, make troubles to use.

The purpose of this utility model is to overcome above-mentioned defective, and a kind of domestic heating stove of energy automatic stoking is provided.

The utility model is to adopt following measure to realize: this family expenses automatic stoking heating stove, the heat pipe that comprises the body of heater that has inner bag, communicates and be in tilted layout with the body of heater inner bag, be furnished with burner hearth, fire bars, the ashcan of concrete wall all around, and communicating with burner hearth is provided with the coal bunker that the bottom is ramped shaped.Because coal bunker bottom absolute altitude is more than burner hearth, formed the coal situation that glides by gravity, the coal of storing in the coal bunker flows to burner hearth along the slope downslide and carries out preheating successively, burns, burns by gravity, falls into ashcan from the fire bars gap then, coal constantly replenishes, thereby realize the purpose of automatic stoking, because the draft that the draft of stove itself forms much larger than coal bunker, and the general maintenance of the cover plate at coal bunker top is normally closed, thereby flame can not enter in the coal bunker.

The utility model has been set up automatic stoking on the basis of existing heating stove structure, need not machine driving, not electricity consumption, can realize the automatic stoking under the natural conditions, have simple in structure, easy and simple to handle, reliable, save time, laborsaving, characteristics such as economize on coal, the normal combustion process only needs in the coal bunker coal one to secondary every day, deashing one is the regeneration product of existing various domestic heating stoves to secondary.
