Abstract

The utility model discloses a firewood furnace, which mainly comprises a furnace body, a feeding channel, a feeding hole cover, a furnace core, ventilation holes, a furnace surface, a furnace cover, a fire hole, a fire blocking ring, a furnace core heat insulating layer, a negative-pressure cavity, a handle, a check bridge, a base, a cinder box and a flue, wherein the feeding channel is formed on the upper middle part of one side of the furnace body; the inner port of the feeding channel leads to the inner wall of the furnace core; the channel inclines downwardly from outside to inside; the outer port of the feeding channel is provided with a feeding cover which can be opened and closed; the furnace core in the furnace body has a double-layer structure; a plurality of uniformly-distributed ventilation holes are formed around the upper part of the inner layer of the furnace core; and a gap exists between the furnace core heat insulating layer and the inner layer of the furnace core, so that the negative-pressure cavity is formed. The firewood furnace has the advantages of complete combustion, high heat efficiency, small amount of dissipated dust, safety and sanitation.

Description

A kind of faggot stove

Technical field

The utility model belongs to the technical field of Domestic stove, especially offers a kind of faggot stove of charge door from the body of heater side.

Background technology

Existing various Domestic stove is various in style but they all are to adopt directly to open top boiler face jet-burner and add fuel, exists reinforced hourglass cigarette, dust also very big, the environmental sanitation around the influence, and it is not energy-conservation to open burner refuelling influence burning.

The utility model content

The purpose of the utility model is the defective that exists to the said Domestic stove of background technology, and design provides a kind of faggot stove that is provided with charge door in the body of heater side, makes interpolation fuel more convenient; And do not leak cigarette in the reinforced process; Do not distribute dust, and the faggot burning is more abundant, saves the energy.

A kind of faggot stove; Mainly constitute, be provided with feeding-passage in the position on the upper side at a middle side part of body of heater by body of heater, feeding-passage, charging flap, combustion chamber, air vent, boiler face, bell, burner, fire-stop ring, combustion chamber heat-insulation layer, negative pressure cavity, handle, grate, base, ash bin, flue; Mouthful lead to the inwall place of combustion chamber in this feeding-passage, and passage tilts downwards outside in, its collar extension also be provided with can switch feed cap; The combustion chamber that is in the body of heater is a double-decker, is provided with equally distributed a plurality of air vent around the top of layer within it; The gapped negative pressure cavity that formed between combustion chamber heat-insulation layer and the combustion chamber internal layer.

Adopt the beneficial effect of the utility model to be: this faggot stove sufficient combustion, the thermal efficiency is high, and it is few to distribute dust, safety and sanitation.

Description of drawings

Fig. 1 is the cross-sectional view of a kind of faggot stove of the utility model.

Among the figure: 1-body of heater, 2-feeding-passage, 2.1-charging flap, 3-combustion chamber, 3.1-air vent, 4-boiler face, 4.1-bell, 5-burner, 6-fire-stop ring, 7-combustion chamber heat-insulation layer, 8-negative pressure cavity, 9-handle, 10-grate, 11-base, 12-ash bin, 13-flue.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further; The body of heater 1 of this faggot stove, boiler face 4, bell 4.1, burner 5, fire-stop ring 6, handle 9, grate 10, base 11, ash bin 12 and flue 13 are all basic identical with common stove and accessory; In a side of body of heater 1 feeding-passage 2 is set, mouth directly leads to the inwall place of combustion chamber 3 in it, and is downward-sloping from outside to inside; Reinforcedly can enter burner hearth, the collar extension of feeding-passage be provided with can switch charging flap 2.1; Combustion chamber 3 in body of heater 1 is double-deckers; The upper position of layer is offered equally distributed a plurality of oval air vent 3.1 within it; Form negative pressure cavity 8 between combustion chamber internal layer and the combustion chamber heat-insulation layer 7, burning makes hot gas get into through the wind hole and gets into flue after negative pressure cavity makes a circulation downwards, and this faggot stove refuelling when heating need not be taken off lid; Boiling water or reinforcedly during cooking food need not hold out cooker, convenient health again.
