Abstract

The utility model discloses a domestic heating stove, which is characterized in that the thermal efficiency ratio of the domestic heating stove is higher than that of the traditional domestic boiler and the relative costs of which is reduced. The utility model has the advantages of cooking meals, heating, taking bathe and more other functions.

Description

The domestic heating stove

Technical field: the utility model relates to boiler, relates in particular to be fit to the small heater boiler that family uses.

Background technology:, due to limited conditions, can not adopt the large tracts of land central heating as the city for vast rural area and middle samll cities and towns.Therefore, the consumer group in this scope should consider the thermal efficiency aspect heating, consider cost again.At present, the family expenses boiler type is various on the market, but also has many shortcoming: good such as the thermal efficiency, and its function singleness; More than the function, its thermal efficiency is low again, and the two can not finely be coordinated.

The purpose of this utility model provides the domestic heating stove after a kind of improve, and it both can be used for cooking, again can heating, can also have a bath, and multi-use, and also the thermal efficiency improves a lot than other heating stove.

Technical scheme: the purpose of this utility model is achieved in that around burner hearth water jacket all is set, and is coal feeding hole directly over the burner hearth, and flame export departs from the center of burner hearth, above the quirk excessively between burner hearth and the flue.

Burner hearth bottom has fire grate, and fire grate is made up of fire grate and scarfing cinder tooth two parts, and fire grate and body of heater are fixed together, and be stiff; After main shaft one end of scarfing cinder tooth passes body of heater, form crank outside body of heater, the other end penetrates in the fire grate, and the scarfing cinder tooth can be movable; On the main shaft of the scarfing cinder tooth between two adjacent fire bars, weld two lengths of rebar shorter relatively than fire bars.

In the utility model, the part chimney has water jacket, and delivery port is positioned at the top of the chimney section that has water jacket.

Crossing in the quirk between flame export and flue is provided with some water pipes again, and the two ends of water pipe are communicated with water jacket, and water pipe tilts to install, and with horizontal plane certain angle is arranged.

Cause the hydraulic pressure increase and cause the water jacket explosion in order to prevent that water temperature is too high, an explosion-proof valve is set on the shell wall of heating stove, explosion-proof pad is arranged in the explosion-proof valve.

Described in detail below in conjunction with accompanying drawing.

Fig. 1 is a stereogram of the present utility model;

Fig. 2 is a cutaway view of the present utility model;

Fig. 3 is the structure diagram of moving grate in the utility model.

As shown in the figure: being provided with water jacket 9 around the burner hearth 10, is coal feeding hole 2 directly over burner hearth 10, and flame export 3 is above the quirk excessively between burner hearth 10 and the flue.

Because flame is in the process of chimney 5 of flowing through, still have a large amount of heats to exist, in order to make full use of this part heat, also have water jacket near this section of body of heater at chimney, and with the Position Design of delivery port 4 top at this section chimney.

Still in order to make full use of heat, in crossing quirk, be provided with some water pipes 13 again, the two ends of water pipe 13 are communicated with water jacket 9, and water pipe 13 tilts to install, and with horizontal plane certain angle is arranged.This kind structure, when water temperature raise, the water in the water jacket can quicken convection current, and water temperature is raise rapidly.

On the shell wall of heating stove 1, be provided with an explosion-proof valve 6, explosion-proof pad 8 is arranged in the explosion-proof valve 6, thereby its objective is and prevent to cause that hydraulic pressure increases causes the water jacket explosion owing to water temperature is too high.

The fire grate of burner hearth 10 bottoms is made up of fire grate 11 and scarfing cinder tooth 12 two parts, and fire grate 11 is weldingly fixed on body of heater 1, and is stiff; Scarfing cinder tooth 12 can be movable, after main shaft one end of scarfing cinder tooth 12 passes the furnace wall, forms crank outside body of heater; The other end penetrates the fire bars of forming fire grate 11, on the main shaft of the scarfing cinder tooth 11 between the two adjacent fire bars, welds two lengths of rebar shorter than fire bars relatively.During use, rotate the crank of scarfing cinder tooth 11, the tooth bar on the scarfing cinder tooth 11 also rotates thereupon, and slag is promptly broken, leak down, and falls in the grey slag bucket 7.

The utility model has following characteristics:

One, multi-use. Can cook, again can heating, can also have a bath.

Two, environmental protection and energy saving. Fire enters the bottom of a pan after burner hearth carries out primary combustion, carry out two Inferior burning is fully burnt effective flue dust, can not pollute to atmosphere.

Three, thermal efficiency height. This stove all is interlayer up to the chimney part up from fire bars, Heating surface area wants big than common heating, so it is express to heat up, and thermal efficiency height.

Four, account at area little. The utility model is simple in structure, compact, account at area little, Its volume only is equal to the size of common stove.

Five, long service life. The distinctive explosion-protection equipment of the utility model can effectively prolong pot The service life of stove, the relative financial burden that has also alleviated the consumer.

Claims

1, a kind of domestic heating stove is made up of body of heater, fire grate, water jacket etc., and it is characterized in that: flame export departs from the center of burner hearth, above the quirk excessively between burner hearth and the flue; Chimney near oven body part has water jacket; The water pipe of crossing in the quirk tilts to install, and with horizontal plane certain angle is arranged.

2, domestic heating stove according to claim 1 is characterized in that: fire grate is made up of fire grate and scarfing cinder tooth two parts, and fire grate and body of heater are fixed together; After main shaft one end of scarfing cinder tooth passes body of heater, outside body of heater, form crank; The other end penetrates fire grate, on the main shaft of the scarfing cinder tooth between the two adjacent fire bars, welds two lengths of rebar shorter than fire bars relatively.

3, domestic heating stove according to claim 1 is characterized in that: an explosion-proof valve is set on the shell wall of heating stove, explosion-proof pad is arranged in the explosion-proof valve.
