Abstract

The utility model relates to a multifunction domestic heating stove which can be used for boiling water, cooking rice and supplying heat. The utility model has an inner and an outer water jackets that use honeycomb briquet as fuel and double flame paths. The utility model is characterized in that the outer water jacket is composed of a circular outer wall and a shaped inner wall. An annular flame path is formed between the outer water jacket and the inner water jacket which is arranged at the center of the outer water jacket, and the shape of the inner water jacket is similar to the shape of the inner wall of the outer water jacket. The center of the inner water jacket forms a center flame path. The two flame paths are directly communicated with a shaped hearth of which the shape is decided by the number of the honeycomb briquets burned. The outer wall of the outer water jacket is higher than the inner wall of the outer water jacket and the inner water jacket. The stove has reasonable design, simple structure, sufficient heat change, comprehensive thermal efficiency of 60.15 percent, individual heating thermal efficiency of 62.37 percent, smoke discharging blackness lower than 0.5 stage (Ringelman) and smoke gas content of 0.42 percent Vol. The utility model is quick in elevating temperature when heating and slow in temperature drop.

Description

Multi-function domestic heating stove

The utility model relates to a kind of is the inside and outside double water jacket of fuel with the honeycomb briquette, the multifunctional civil heating stove that can heat up water, cook, heat of double-fire channel.

The civil heating stove of Chu Shouing has single fire passage, single water jacket, single fire passage double water jacket in the market, double-fire channel double water jackets etc. are planted pattern, of a great variety, different, but that its structure all exists heating surface area is little, and heat exchange is not too abundant, the shortcoming that overall performance is relatively poor, because leaving water temperature is lower, indoor temperature rises slowly during heating, and the back water temperature of banking up a fire descends very fast again.

To be exactly that design is a kind of do rational in infrastructure, the sufficient double water jacket of heat exchange of fuel, the multifunctional civil heating stove of double-fire channel with honeycomb briquette to the purpose of this utility model, improves the overall performance of stove, realizes rapid high temperature heating, and the back water temperature of banking up a fire is slowly descended.

Multifunctional civil heating stove described in the utility model is by the ring oven of the upper of furnace body outer water jacket in external one week of wall, with the corresponding annular inner water sleeve of special-shaped burner hearth shape.The annular quirk that forms between the inside and outside water jacket.Heat absorbing sheet on the annular quirk, the communicating pipe of water jacket inside and outside being communicated with, the special-shaped burner hearth of body of heater bottom, the upper hose of burner hearth outside, the parts such as arc water inlet pipe that are positioned at lower furnace portion that are communicated with upper hose constitute.Water at low temperature at first enters outer water jacket, behind the expanded by heating, enters inner water sleeve through communicating pipe, is subjected to secondary high temperature heating back and discharges body of heater.Be used for covering at inner water sleeve fire-suppressing cover suitable for reading outside the heating separately.At this moment, flame mainly enters annular quirk through L shaped heat absorbing sheet, directly roasts inwall, communicating pipe and the outlet pipe of the end opening of inner water sleeve and outer wall, outer water jacket.All the other flames then enter the center quirk of inner water sleeve, directly roast inwall.So both increased the heating surface area of water jacket, water at low temperature is heated rapidly.Be used to heat up water when cooking, get lower fire cover.At this moment, flame is concentrated barbecue cooker bottom.Be subjected to the flame of cooker damping, when directly roasting inner water sleeve end opening and its inwall, also will enter annular quirk, roast all the other all heating surfaces.The outer wall of outer water jacket is higher than its inwall and inner water sleeve in when design, cover fire sealing cover after, center quirk and annular quirk all are communicated with at two two ends up and down, so bank up a fire afterwards that it still is in the normally in service of backwater, preheating, post bake, high-temperature water outlet.

Multifunctional civil heating stove described in the utility model is reasonable in design, simple in structure, and heat exchange is abundant, and its integrated heat efficiency reaches 60.15%, and the heating thermal efficiency reaches 62.37%, oke exhaust blackness＜0.5 grade (Lin Geman), content of CO in smoke 0.42%Vol separately.

Embodiment:

Below in conjunction with accompanying drawing multifunctional civil heating stove structure described in the utility model is described in detail.

11. heat absorbing sheet

Surround outer water jacket 3 outer walls that diameter is φ 336mm with iron plate, make annular inner water sleeve 5 inwalls that the center just in time can be put into three honeycomb coalies simultaneously with iron plate then, make the inner water sleeve outer wall and the outer water jacket inwall of same shape again with iron plate, between them, form an annular quirk 9 that communicates with following burner hearth 12.In inner water sleeve, be formed centrally a center quirk that communicates with following burner hearth.With lower wall sealing on the inside and outside water jacket, make the outer wall of outer water jacket be higher than inwall and inner water sleeve.On the annular quirk between the inside and outside water jacket, connect and seven communicating pipe 4 inside and outside water jacket is communicated with.Evenly distribute on annular quirk and adorn nine groups of L shaped heat absorbing sheets 11, with outer water jacket inwall, the outer wall and the end opening of inner water sleeve weld together respectively.Burner hearth is positioned at the below of inside and outside water jacket, is to be made of the quincunx tile that can put three honeycomb briquettes.Three arc water inlet pipes 7 that communicate with water inlet 1 are installed below burner hearth.Burner hearth outside install three vertical upper hoses 6 with water inlet pipe with outside water jacket be communicated with.Two outlet pipes 8 are installed on inner water sleeve.Burner hearth also can be made single hole, diplopore, porous form according to the consumption of honeycomb briquette.The shape of the annular quirk that the inwall of inner water sleeve, outer water jacket and they constitute also can formalize according to the burner hearth shape that the honeycomb briquette different amounts is formed.Stove has fire-suppressing cover 2.
