Abstract

The utility model discloses a three-purpose quick energy saving stove which can use coal, chark and firewood. The three-purpose quick energy saving stove is that the flank of the existing coal stove is provided with a firewood door and is matched with a fireproof inner plug. Fire bars can be lifted and descended, and three bulgy fulcrums are arranged on the fire bars and are used for aerially supporting a coal base. In addition, the inner flank of the wind-proof ring of the upper side of the hearth is provided with three convex down-draft ribs for helping discharging exhaust gas. The hearth and the fire bars of the three-purpose quick energy saving stove are public, the fire bars can be also lifted to keep optimum distance to a pan bottom when the three-purpose quick energy saving stove burns firewood and chark. The three-purpose quick energy saving stove has good ventilation and complete combustion, and the heat efficiency reaches 45% when the three-purpose quick energy saving stove burns firewood. Compared with the existing coal stove, the heat efficiency of the three-purpose quick energy saving stove is respectively improved by 11% and 30% when the three-purpose quick energy saving stove burns coal and chark.

Description

Three purpose quick energy saving stove

The utility model relates to a kind of home furnace.

A kind of three purpose stove of market sale is at present established a chamber of a kitchen range, and is opened a wooden door in the side above common coal stove, burn " honeycomb briquette " in the coal stove, also can make charcoal, and the chamber of a kitchen range then burns bavin, thereby reaches the purpose of " three usefulness ".The shortcoming of this three purpose stove is: when (1) burns bavin, in coal stove, put 2～3 Hongcomb coal-slags earlier, and as the fire bars of the chamber of a kitchen range, the ability catching fire, the cinder hole very easily is blocked, and causes improper ventilation, and the oxygen supply deficiency makes that the burning of firewood is incomplete, and flue dust is big; (2) in like manner, also can cause burning bad when making charcoal because of the charcoal ash stops up the cinder hole.

The purpose of this utility model provides a kind of ventilation well, and the fast energy-saving stove is used in burning novel completely three.

For achieving the above object, the utility model improves on the basis of existing coal stove, opens by one " wooden door " all public this burner hearth when making coal combustion, bavin, charcoal in the side of coal stove thorax; And the fire bars of coal stove, the activity of then being designed to, lowering or hoisting gear of beneath design, this fire bars is positioned at the bottommost of burner hearth when burning coal, when burning bavin and making charcoal this fire bars is raised to a suitable position, so that the burning of faggot and charcoal.The wooden door of opening in order to make does not influence the burning coal, makes charcoal, and should be equipped with one and the equirotal fire-resistant interior plug of wooden door, blocks wooden door when burning coal usually, keeps the complete of burner hearth.

Existing fire bars is when burning coal, because the fire bars face is flat, has coal hole greatly blocked, and influence is ventilated.In order further to improve ventilation, increase burning of coal speed, the utility model is provided with several ridges on the surface of fire bars, as the fulcrum at the bottom of the coal, at the bottom of the built on stilts coal, thereby improved ventilation condition.

Existing coal stove is provided with a circle wind loop in order to prevent the convection current air influence around furnace outlet.If this wind loop is tight with the bottom of a pan contact, will hinder the discharge of waste gas, influence the burning of fuel, particularly having the greatest impact to firewood.Remain certain clearance in order to make between all kinds of thes bottom of a pan and the wind loop, the utility model has designed three especially and has protruded from the wind loop medial surface, the downdraf muscle of distribution triangular in shape, it makes of all sizes, remain suitable gap between the variform the bottom of a pan and the wind loop, guaranteed the smooth discharging of waste gas.

The advantage of the utility model three usefulness fast energy-saving stoves is: (1) burner hearth and fire bars are that coal, bavin, charcoal are public, good heat insulation, and one time wind ventilates, and fuel combustion is fully, rapidly; Fire bars can be risen to suitable height when (2) burning bavin and making charcoal, keep optimum distance, both can conveniently burn, can save the energy again with the bottom of a pan; (3) also be provided with the fulcrum of several protrusions on the fire bars, can make somebody a mere figurehead at the bottom of the coal, improve burning of coal speed, reduce coal consumption; (4) be provided with protrusion at the medial surface of wind loop, the downdraf muscle of distribution triangular in shape can make between the different the bottom of a pan of all kinds of size shape and the wind loop and remain suitable gap, guarantee the smooth discharging of waste gas.

Embodiment to the utility model three usefulness fast energy-saving stoves is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the positive view of the utility model three usefulness fast energy-saving stoves.

Fig. 2 is the vertical view of the utility model three usefulness fast energy-saving stoves.

As seen from Figure 1, Figure 2, these three usefulness fast energy-saving stoves are by shell (14), be positioned at the flue (13) of shell central authorities, fill the heat-barrier material (15) between shell and the flue gap, be positioned at an air vent (8) of flue bottom sides and the enclosing cover (9) that matches, be positioned at the fire bars (12) of an air vent top, be positioned at the wind loop (2) and the widely different wind sheet compositions such as (3) of the multi-disc between wind loop and flue of flue upper periphery.In addition, also above an air vent, a wooden door that communicates with burner hearth (6) has been opened in the side of shell to the utility model, and is furnished with a corresponding fire-resistant interior plug (5), and wooden door is designed to movable, and is furnished with a keeper (4); Fire bars frame of the present utility model is on three fire bars framves (10) that protrude from the flue inner surface, three legs (11) are equipped with in the bottom of fire bars, top is provided with the fulcrum (7) of three protrusions, and this fire bars frame is on the fire bars frame, shown in the solid line fire bars among Fig. 1 when burning coal, burn bavin or when making charcoal, fire bars is promoted, with its leg frame on the fire bars frame, like this, fire bars has just raise, shown in the dotted line fire bars among Fig. 1; The utility model also is provided with the downdraf muscle (1) that protrudes from the side of three distributions triangular in shape at the medial surface of firestopping ring, no matter the bottom of a pan of all kinds of different size shape can both cooperate with it, keeps suitable gap, guarantees the smooth discharging of waste gas.

Experimental result shows that the thermal efficiency that the utility model three usefulness fast energy-saving stoves burn bavin can reach about 45%, burns coal and improves the thermal efficiency about 11% and 30% than common coal stove respectively with making charcoal.
