Abstract

The utility model relates to a coal-saving stove which is provided with a pair of sealing stove doors whose interior is provided with a secondary air inlet valve. Meanwhile, a hearth mouth is provided with a concave annular heat accumulation tray which is used for enhancing the matching sealing performance between the stove doors and a stove body and the secondary ventilation performance of the stove body. Thus, the utility model can ensure sufficient combustion of the fuel in the stove and improve the heat efficiency. In addition, the lower side of the hearth is also provided with an air distributing and ash discharging box which is favorable to automatic air distribution of the stove body and the self air combustion. Thus, the utility model can ensure sufficient wind pressure desired by the combustion. The utility model has the advantages of high thermal efficiency, high ignition speed, coal saving, cleanness, sanitation, etc.

Description

Domestic efficiency coal-saving stove

The utility model belongs to the manufacturing field of civilian burning cooking stove, the tangible civilian high-efficient coal-saving kitchen range of particularly a kind of combustion thermal efficiency height and energy-saving effect.

Present vast rural area of China and cooking heating kitchen range for being continued to use in the suitable town dweller family of number, its thermal efficiency all very low (only is about 15% according to surveying), get angry slow and smoke contamination serious, the ecological balance and health of human body are all being caused great harm in varying degrees.

The purpose of this utility model is to overcome the above-mentioned shortcoming of original burning cooking stove, produce a kind ofly have that thermal efficiency height, the speed of getting angry are fast, fuel savings, elimination room air pollution and alleviate the civilian high-efficient coal-saving kitchen range of advantages such as outside atmosphere pollution.

In order to realize above goal of the invention, design of the present utility model is taken pains the fitted seal performance strengthened between burning kitchen range kitchen range door and stove and the twice aeration performance of stove, its architectural feature is that the sealing kitchen range door that a pair has the secondary air valve is set on stove, be provided with a scrobicular ring shape heat-collecting disc of controlling and cut off the outside conduction of heat in the kitchen range made from high-temperature refractory simultaneously at chamber of a kitchen range mouth place, can guarantee the abundant burning of fuel in the kitchen range by the design of this novel kitchen range door and heat-collecting disc, improve the thermal efficiency.In addition, below the chamber of a kitchen range, also be provided with an air distribution ash discharge case that helps stove to carry out air distribution automatically or burn, to guarantee the required enough blast of chamber of a kitchen range burning from wind.

Below with reference to accompanying drawing content of the present utility model is further described

As shown in the figure, this civilian high-efficient coal-saving kitchen range is made of kitchen range shell 1, kitchen range door, the chamber of a kitchen range 2, kitchen range drawer 3, air distribution ash discharge case 4 and heat-collecting disc 9 of being located at chamber of a kitchen range mouth place etc.The kitchen range shell is built into by common square brick.The kitchen range door is located at a side of kitchen range shell, form by kitchen range door frame 5 that is sealed and matched mutually and kitchen range door-plate 6, kitchen range door-plate 6 is circle, rectangle or Else Rule shape, and the place of being sealed and matched of kitchen range door frame 5 and kitchen range door-plate 6 has all carried out accurate processing through lathe, thereby has excellent sealing performance.Above kitchen range door-plate 6, be provided with a flame-observing hole 61 that is covered with removable lid.Below kitchen range door frame 5, be provided with two side by side and be used to supply the

rectangle valve

51,52 that heat-collecting disc 9 secondary hot-airs enter in the kitchen range.Heat-collecting disc 9 is formed by the high-temperature refractory extruding, because refractory material itself has very little conductive force, thereby also just control and cut off the outside conduction of heat in the kitchen range effectively, greatly improved heat reflection, thermal convection current and the heat conduction of flame, so also just saved fuel significantly pot body 10.The external diameter of heat-collecting disc 9 suitably cooperates with the size of pot body 10, and shape is similar to the top of funnel, is the scrobicular ring shape, and relative with the chamber of a kitchen range in the middle jet-burner that advances has been made bell mouth shape, so that make the flame in the kitchen range converge concentrated.In axial direction be provided with 4～6 group of two air intake passage 91 on the heat-collecting disc 9 closely symmetrically, and have many apertures (representing with close point among Fig. 6) to feed its ring-type booster zone and the combustion zone of advancing jet-burner.When flame after entering heat-collecting disc 9 under the suction function, formed the high-temperature region, and fully burning under the oxygen supply of secondary hot-air, discharge a large amount of heat energy, the effect of two air intakes is not have clean-burning CO gas to carry out oxidizing fire once more for 9 pairs of heat-collecting discs, these gases after secondary air combustion-supporting down emitted certain heat again, just through exhaust passage 11 around one week of pot edge the back from flue 12, be discharged from.It is very little that the waste gas of being discharged in this modified cooking stove contains the cigarette amount, and environmental pollution has been reduced to minimum degree.Air distribution ash discharge case 4 described in the utility model is positioned at the below of the chamber of a kitchen range 2, and it is processed by cast iron.Be provided with a pivot 41 at the middle part of this case, be hinged with a wind acanthus leaf 42 that these case 4 casings can be divided into two air compartments on pivot 41, wind acanthus leaf 42 has higher precision with casing 4 inside and cooperates.Through 42 of wind acanthus leafs every two air compartments communicate with blower fan air inlet duct 7 and bellows air inlet duct 8 respectively, when the user carries out air blast 13 air distributions (Fig. 4) or bellows 14 air distributions (Fig. 5) to stove, wind acanthus leaf 42 can form an airtight space around pivot 41 automatic deflections, to guarantee having enough blast in the air compartment.When wind burnt, the plate face of wind acanthus leaf 42 vertical (as shown in Figure 2) was because the effect of laying particular stress on of plate has promptly formed from the wind passage at stove.On the rotation pivot 41 of wind acanthus leaf, miniature bearing and sealing gasket are housed also, to guarantee performances such as it is wear-resisting and dustproof.Be provided with a secondary ash discharge valve 43 that constitutes with involutory elastic plate in the lower end of air distribution ash discharge case, when not having lime-ash to fall, valve 43 is closure state at ordinary times, and when lime-ash falls thereon and reaches constant weight, valve 43 is just opened ash discharge automatically, and row returns to closure state after finishing once more.

Civilian high-efficient coal-saving kitchen range provided by the utility model is suitable for vast rural area and urban household most and uses, and it also can be held concurrently and burn bavin, grass, straw or other multiple charcoal mineral matter to burn coal.The good looking appearance of this kitchen range, easy to use, clean hygiene, according to surveying its thermal efficiency up to about 58%, if calculate by 3～8 mouthfuls of people's family, year can economize on coal more than 1.5 tons, as in the whole nation most of areas promoted, its economic benefit and social benefit all will be very considerable.
