Abstract

The utility model relates to a heater burning indoors, which is formed by that a common burning heating furnace is additionally provided with an intake tube. When burning for heating, the burning furnace can get outdoor air directly through the intake tube with a heavily shielded tube wall and avoid the heat exchange between indoor and outdoor places resulting from the air usage of the burning furnace. The utility model can be used for high efficiency and energy-saving indoor heating.

Description

Heater supplying combustion-air indoor

The utility model relates to a kind of heating of house device, especially a kind of Indoor Combustion heating installation.

Existing Indoor Combustion heating installation is made up of stove outer covering, furnace chamber, air inlet and the dual-purpose fire door of grate furnace ash, smoke collecting chamber, outlet flue and chimney etc.When the fuel combustion in the stove, emit a large amount of heat, by body of heater, heating such as chimney room air; Simultaneously, indoor heated air also constantly enters in the stove from fire door, and is outdoor by the chimney discharge at last, and outdoor cold air also just constantly adds to indoor, causes the exchange of indoor and outdoor heat thus, has reduced the thermal efficiency of heating of house.

Task of the present utility model provides a kind of Indoor Combustion heating installation from outdoor direct air inlet, and it can stop the exchange of the indoor and outdoor heat that causes because of stove internal combustion usefulness gas effectively.

For solving above-mentioned task, the solution that the utility model adopts is: increase the heavily-shielded air inlet pipe of tube wall on common heating combustion furnace, one end of air inlet pipe closely is connected with the air inlet of stove, the other end places on the outdoor alap position, and the tube wall of air inlet pipe, furnace shell all should seal preferably.When with stove burning heating, stove can so just stop the exchange of the indoor and outdoor heat that causes because of stove internal combustion usefulness gas by air inlet pipe directly from outdoor air inlet.

Above-mentioned air inlet pipe, can closely be pegged graft with heat-barrier material by the outer bread of common iron sheet chimney easily forms again; Also can make by the good material of other thermal insulations.

Side drum wind-powered electricity generation fan can be set in the air inlet pipe, when fan changes air inlet fast, indoor quick heating; It when fan does not change the natural inflow state.

Owing to adopted in the above-mentioned solution air inlet pipe that combustion furnace has well heat insulation a, sealing property by tube wall directly from the mode of outdoor air inlet, so can or not add to indoor owing to stove internal combustion usefulness gas makes indoor hot-air run out of outdoor, outdoor cold air by chimney yet, this has improved heating of house efficient with regard to having stoped the exchange of the indoor and outdoor heat that causes because of stove burning usefulness gas effectively.Under similarity condition, the utility model also has than ordinary heating stove economizes on coal the advantage that indoor temperature rising speed is fast.

Below in conjunction with drawings and Examples the utility model is described in further detail.

With reference to Fig. 1, a burning warming stove shell (1) can be made by cast iron or iron sheet, and shape can be a cylindrical shape or square etc.There is coal holder (4) below in the stove, places cylinder or square tube shape combustion chamber (2) in the coal holder, can place honeycomb briquette in the furnace chamber (3), and the fire door (5) of cast iron is placed in combustion chamber (2) upper shed, and when banking a fire, an available bell covers fire door (5).There is smoke collecting chamber lid (7) smoke collecting chamber (6) top, and the smoke collecting chamber outlet is exactly the interface (8) of chimney (9), and its shape, size should make chimney (9) jacket-type insert.There is an insertable washer (11) in fire door (10) outside.Open the air admission hole (12) of a circle at stove outer covering (1) downside, its size should make air inlet pipe (13) closely insert.In air inlet pipe (13), also has the fixing AC permanent magnet small machine (16) of the support that is fixed (15), press an axial-flow type air blast flabellum (14) in its rotating shaft, flabellum (14) is 2 elongated leaf formula structures, and the supply hub of motor (17) can be fixed on 3.5 millimeters insert earphone jacks on the air inlet pipe (13) and make.The common iron sheet chimney of the available some joints of air inlet pipe (13) (quantity is by user's border situation oneself selection factually) is closely pegged graft and is formed, " turning round " can be arranged therebetween, the chain-dotted line of air inlet pipe among Fig. 1 (13) is partly represented the abridged technique of painting, has wherein comprised " turning round ".The appearance of air inlet pipe (13) and should wrap a little heat-barrier materials, as cloth, foamed plastics etc., but joint needn't wrap with inboard, junction one end between the joint.The available iron plate of washer (11) of fire door (10) is made, and as shown in Figure 4, its shape, big or small Ying Yineng cover fire door (10) completely and the chute (18) that can insert as shown in Figure 3 is as the criterion.Each 1 of chute (18) in fire door (10) both sides, available iron plate is made, and is fixing with screw (19) in its outside, and lateral bending goes out to make the tight gap of inserting of washer (11) within it again.Fig. 2 has provided air inlet (12) for circular.

Blower motor (16) can be fixed in the air inlet pipe (13) by shown in Figure 5.The fixed support (15) of blower motor (16) can pack tightly motor by two iron plates by shown in Figure 6, than air inlet pipe (13) interior diameter weakness slightly, two iron plates curve and can make it closely insert the shape of air inlet pipe (13), and two iron plates can be kept by clamping screw (20) the chucking power of motor (16).The available plastic injection-moulded shaping of air blast flabellum (14) also is fixed in plug in construction in the rotating shaft of motor (16).Above-mentioned relevant way is for the ease of changing motor (16).The toy permanent magnetism small DC motor of the available cheapness of motor (16); Little, the durable motor of also available other body.The power supply of motor (16) can be used battery, also available common rectifier power source, and attaching plug is with 3.5 millimeters insert earphone plugs.

Above-mentioned relevant technologies feature of the present utility model can correspondingly be done following variation, but they all do not depart from essence of the present utility model.For example, air inlet pipe (13) also can be made other shape, and as square, oval, triangle tube etc., but the shape of air inlet (12) also should correspondingly change, and closely pegs graft to guarantee both.The mode that air inlet pipe (13) and air inlet (12) join also can be that screw is fixed, snap-in etc.If the air inlet pipe (13) and the connected mode of air inlet (12) are changed into the snap-in structure of band chute (similar) with fire door washer fixed form among the embodiment, can not offer fire door (10), air inlet pipe (13) can be removed air inlet (12) when getting the coal quarrel and get final product.Air inlet pipe also can be made by other materials, and as plastics, paper fiber, wood-fibred or the like, but the air inlet pipe of making is must thermal insulation good, and tube wall is air tight as far as possible.The also available common coal of the fuel of stove, coal gas, natural gas etc., but furnace chamber is wanted respective change.
