Description

The domestic heating stove

The utility model relates to domestic heating equipment, and more clearly saying so is in is used for heating, boils water and does the domestic heating stove of meal in the subsections such as front yard and little shop, little post office.

The domestic heating stove in past (being commonly called as native heating installation), its thermal efficiency is lower, and energy waste is bigger.Because its design is reasonable inadequately, cost of manufacture is higher, and manufacture craft is also complicated.In addition, the domestic heating stove in past is installed intercalated water sleeve between tile and shell, filling heat insulating wall between shell and the intercalated water sleeve, and this has improved manufacturing cost and price again.

The purpose of this utility model is to overcome above-mentioned shortcoming and defect, provides a kind of design through improving, and the thermal efficiency is higher, and energy-saving effect is better; Manufacture craft is simple, and body of heater and intercalated water sleeve are one, thereby can reduce the domestic heating stove of manufacturing cost and price.

In order to achieve the above object, the utility model domestic heating stove is by base, be fixed on the body of heater that has bell or stove circle on the base above it, being fixed on body of heater bottom and base constitutes jointly on the grey chamber of grey chamber and encloses, be installed in the fire door on the front openings of grey chamber, be installed in the fire grate at circle middle part on the grey chamber, be fixed on the middle cylindric tile that forms burner hearth of fire grate, be fixed on the tile water jacket of its interior water-filling on every side, return pipe that is positioned at its lower end that is welded on the water jacket and communicates and the outlet pipe that is positioned at its upper end with water jacket, be filled in the insulation filler between tile and the water jacket, being fixed on upper of furnace body throat that links to each other with burner hearth and the chimney that is fixed on the throat constitutes.A chimney water jacket is also being welded in outside, chimney middle and lower part, and an outlet pipe is being welded in the upper end of chimney water jacket, and a water inlet pipe is being welded in the lower end, links to each other with water pipe between the outlet pipe of water jacket and the water inlet pipe of chimney water jacket.

In the utility model when work,, the backwater in the heating system is entered by the return pipe of water jacket, enters heating system through the outlet pipe of water jacket, the outlet pipe that connects water inlet pipe, chimney water jacket and the chimney water jacket of water pipe, chimney water jacket successively through heated hot water.In this course, high-temperature flue gas in the burner hearth earlier with water jacket in the water heat-shift, enter chimney after, be not direct discharge, but again with chimney water jacket in the water heat-shift.Heat in the flue gas is absorbed through twice, and the temperature during discharging reduces greatly.This has just saved the energy, has improved the thermal efficiency.This structure in past normally directly is connected making to water jacket and chimney water jacket, and processing technology is poor, and manufacturing cost is higher.The utility model is connected with the water inlet pipe welding of the outlet pipe of water jacket and chimney water jacket or with pipe joint with water pipe, has improved manufacturability greatly, has reduced manufacturing cost.

Body of heater of the present utility model is made of with skin is two-layer internal layer.Internal layer and outer welding form intercalated water sleeve at the middle part, and making water jacket and body of heater is integral structure.This structure labor and material saving has reduced cost.As cladding one deck heat-insulation layer again in the body of heater outside, can further energy savings.Also can add casing again, make outward appearance clean and tidy in the heat-insulation layer outside.

The splitter that becomes 20～40 ° of inclinations angle with vertical plane of 15～21 U-shapeds of the inboard welding of upper of furnace body, further energy savings improves the thermal efficiency, better effects if.20～40 ° the splitter of tilting makes the flue gas that rises along furnace body inside form vortex, fully to carry out heat exchange.Meanwhile, 15～21 splitters are equivalent to a heat dump.Heat in the flue gas is fully absorbed the back conduction give water jacket.Splitter is during more than 21, and is too big to the resistance of flue gas.When being less than 15, the effect of shunting and heat absorption is relatively poor.

Task of the present utility model comes to this and finishes.

The utility model design is more reasonable, good energy-conserving effect, thermal efficiency height.Manufacturing process is simple, and production cost is lower.Compare energy-conservation 5～12% in the past.Its thermal efficiency can reach more than 75%.Production cost then is reduced to 80～90% of the past.It can be widely used in family, little shop, little post office and other little occasion heating, boil water, do in the meal.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.

Fig. 1 is the structural representation of the utility model embodiment 1.

Fig. 2 is the A-A cutaway view of Fig. 1.

Shown in Figure 1, embodiment 1 by enclose 5 on base 1, the body of heater 3 that has stove circle 2, the grey chamber, grey chamber 4, fire door 6, fire grate 7, tile 9, burner hearth 8, water jacket 10, return pipe 11, outlet pipe 12, insulation filler 13, throat 14, chimney 15 constitute.Outside, chimney 15 middle and lower parts is welded with chimney water jacket 16, outlet pipe 17 and water inlet pipe 18.Be connected with water pipe 19 with joint between outlet pipe 12 and the water inlet pipe 18, technology is simple.Body of heater 3 forms intercalated water sleeve 10, integral structure labor and material saving by internal layer 20 and outer 21 welding backs.Its outside also can clad heat-insulation layer or further increase shell.The splitter 22 of body of heater 3 upper outside welding becomes 30 ° of inclinations angle with vertical plane.

Shown in Figure 2, splitter 22 is positioned at body of heater 3 upper inner, has 16, becomes U-shaped.

Embodiment 1 thermal efficiency reaches 75%, and is energy-conservation 10%, can be widely used in the family.
