Abstract

The utility model relates to a multipurpose combined stove burning coal, firewood and gas, and is an improvement on the traditional civil energy-saving stove, so one stove can use various kinds of fuel. The utility model basically comprises a stove body, a pan platform, a stove door, an air inlet and a chimney, and is characterized in that an increasing pipe whose upper part is big and whose lower part is small forms a stove core on which a stove grate, gas chamber or a honeycomb coal burning chamber can be changed and arranged to realize burning with various kinds of fuel. The utility model has multifunction, good effect of reducing dust, high thermal efficiency, and obvious effect of saving energy, and can be widely used in the families in the urban and rural areas.

Description

Multipurpose combined stove burning coal, firewood and gas

The utility model relates to the domestic life cooking stove, particularly a kind ofly can use the combination stove of using that coal, bavin, gas acts as a fuel body of heater inner conversion more.

Traditional domestic life cooking stove can only act as a fuel with coal, bavin, gas singlely, and in same cooking stove, three kinds of fuel can not exchange use, and this makes troubles to people's life.Numerous residents are owing to the shortage for the moment of certain fuel, and it is not good to originate, or for consideration economically, or restricted by housing condition, be difficult to buy simultaneously multiple cooking stove.For this reason, transform traditional cooking stove, realize the pluralities of fuel dual-purpose, have realistic meaning.Chinese patent application number 91214017.8 disclosed a kind of " the coal bavin is used combination stove more ", the combined type stove heart that the stove heart combines about having adopted, fire door is divided into two sections structure with flat board, has realized the conversion dual-purpose of two kinds of fuel of coal bavin in co-using stove.But this cooking stove fails to realize the combustion gas dual-purpose, moreover fire door need be transformed, and stove heart structure is heavy, and it is inconvenient that displacement is still felt.

The purpose of this utility model be to provide a kind of in same stove the combined stove of flammable bavin, coal, gas pluralities of fuel, and take measures textural, make the transformation of traditional cooking stove more simply, the displacement of the stove heart is more convenient.

The purpose of this utility model is achieved in that it has kept the essential structure of traditional cooking stove, and parts such as shaft, the kitchen sink, fire door, air inlet, chimney mainly are that the stove heart is transformed.Constitute the stove heart with a up big and down small increaser, filling heat insulation preservation material around it, the increaser upper port is shelved grate or fuel chamber, or inserts honeybee coal combustion chamber.

The metal-cored shell of the cylinder combustion chamber that honeybee coal combustion chamber is made by refractory material, parcel combustion chamber and the cross grate that is positioned at combustion chamber bottom constitute, and core shell outer wall has step, in order to the height location of combustion chamber.

Fuel chamber is made of air inlet pipe, gas control valve, gas nozzle, mixture pipe, the gentle lid of dicyclo air chamber.

After above-mentioned improvement, the utility model can be realized the exchange of coal, bavin, three kinds of fuel of gas by change furnace combustion chamber and grate in the heart.Because adopt pipe sleeve structure mode between the stove heart and the combustion chamber, butt joint is accurate, displacement is convenient.The utility model multi-use is used the honeybee coal stove or the gas-cooker of single-fuel relatively, and smoke medicining dust-removing effect is good, sanitation and hygiene, thermal and insulating performance is good, thermal efficiency height, energy-conservation obviously, suit in urban and rural residents, to apply.

Embodiment is described further below in conjunction with accompanying drawing:

Generalized section when Fig. 1 loads onto honeybee coal combustion chamber for the utility model;

Fig. 2 is fuel chamber's generalized section;

Fig. 3 is the grate cutaway view;

Fig. 4 is the grate vertical view.

As shown in Figure 1, the utility model has shaft (9), the kitchen sink (7), fire door (8), air inlet (13), chimney (1) part, leads in the flue (3) of chimney (1) at burner hearth to be provided with adjustable smoke blocking board (2).There is a up big and down small increaser (10) to constitute the stove heart in the stove, its central axis is facing to center, the bottom of a pan, increaser (10) is filled heat preserving and insulating material (11) on every side, increaser (10) lower port is stamped the air door lid (12) of the adjustable intake of rotation, and communicate with air inlet (13), damper can be controlled stove fire intensity.

The metal-cored shell (4) of the combustion chamber that honeybee coal combustion chamber is made by refractory material (5), parcel combustion chamber (5) and be positioned at cross grate (6) formation of combustion chamber (5) bottom, its inwall is a cylindrical shape, can put into the honeybee coal, outer wall is the cylinder that two joints link to each other, form step one in the junction of cylinder, but following pitch cylinder skewer is gone in the increaser (10), and step is stuck in the increaser upper port, locatees in order to the combustion chamber height.

As shown in Figure 2, fuel chamber is made of air inlet pipe (18), gas control valve (19), air nozzle (17), mixture pipe (16), dicyclo air chamber (15) and gas lid (14).The center of dicyclo air chamber (15) is a through hole, around through hole twice annular concentric cavity is arranged, interior ring communicates with mixture pipe (16), the upper end is covered with the center through hole gas lid (4), its through hole communicates with air inlet, as an air intake, between gas lid (14) cylindrical lower edge and ring wall, leave the space, combustion gas can be from overflowing therebetween; The outer shroud upper port is opened wide, and the bottom has through hole to communicate with air inlet (13), as secondary air, impels burning more abundant, and fuel chamber's lower port external diameter should adapt with increaser (10) upper end horn mouth, can pack into easily or take out.

As shown in Figure 3, grate (20) rests in the horn mouth of increaser (10) upper end, and its external diameter and increaser (10) upper end horn mouth adapts, and puts into convenient to remove.

Use of the present utility model is such: if shelve grate (20) on increaser (10), be wood stove, make fuel with bavin: take out grate (20), the honeybee coal combustion chamber of packing into can be coal-fired; If load onto fuel chamber, and insert fuel gas source, i.e. combustible gas.During use, damper covers the intake of (12), can control the combustion intensity of stove fire, can be used to seal stove fire when coal-fired.Also can take off when certainly, firing bavin or combustion gas need not.
