Abstract

The utility model relates to a multi-function domestic warming stove, which can be used for cooking, bathing and heating. The utility model is characterized in that a water storage device is composed of a water jacket and a water box, and the water jacket is installed at the recessed part of a U-shaped gas channel in the stove body; a thermal insulation layer is arranged between the U-shaped gas channel and a stove tile; the structure has the advantages of sufficient coal burning and sufficient afterheat utilization. The utility model has the advantages of high thermal efficiency, sanitation and cleanness, and has fixed and movable grates for combusting honeycomb briquettes or other briquettes and lump coal.

Description

Multi-functioal civil heating furnace

The utility model relates to a kind of solid-fuelled domestic burners, especially is used as the domestic burners of cooking, shower and winter heating and attached hot water apparatus.

Existing domestic burners is varied; improvement project is a lot of for number; wherein great majority all are in order to raise the efficiency, to save the energy and be beneficial to environmental protection, disclosing a kind of stove that utilizes waste heat as 88211105.1 patent applications; it has dress water bell and water jacket; but overlap heating because of its burner hearth directly supplies water, the temperature of burner hearth reduces easily, and fuel is difficult to abundant burning; and the sensible heat utilization of being with is also owed fully in the flue gas, so efficient is difficult to further improve.

Task of the present utility model is to disclose a kind of can fully the burning, can make full use of waste heat again, thereby have high efficiency, has the many coals of burning concurrently, is beneficial to the double multifunctional furnace of doing cooking, shower, heating of the advantage of environmental protection.

Furnace binding: the center is the tile (burner hearth) that refractory material is made; Burner hearth peripheral hardware one thermal insulation layer; Thermal insulation layer is outward the U-shaped exhaust gases passes; The recess of U-shaped exhaust gases passes is provided with ring-shaped water jacket; U-shaped exhaust gases passes outside is a furnace shell; Bell has the water box, and water jacket and water box all are provided with water inlet pipe and water outlet pipe, and the delivery port of water jacket and water box water inlet are connected with flexible pipe during use.The interior ring of U-shaped exhaust gases passes communicates with water box bottom, outer articulating chimney, and the burner hearth lower end is provided with rigid grate and movable furnace grate, change during different coal so that burn, the bottom of U-shaped exhaust gases passes is opened ash output opening for heavy grey chamber at the corresponding site of furnace shell, is the solid-holding bucket below the fire grate.

The coal-fired heat that produces of the utility model at first adds the hot water box, the hot flue gas of returning of turning back enters the interior ring of U-shaped exhaust gases passes, entering chimney through outer shroud again discharges, because tile has thermal insulation layer outward, guarantee that burner hearth is in higher temperature, be beneficial to abundant burning, hot gas heats to water jacket in the both sides and the bottom surface of water jacket, UTILIZATION OF VESIDUAL HEAT IN has fully improved the thermal efficiency, water is heated by two-stage in water jacket and water box, and outlet temperature is higher, can lead to the heating of low-grade fever device, leading to shower uses, remove bell, change pot and can be cooking, the flue sealing, and flue dust is few, the favorable environment health.

Description of drawings:

Fig. 1 is the structure chart of the utility model embodiment;

Fig. 2 is that this implements novel connection external equipment (low-grade fever device, shower) schematic diagram;

Fig. 3 is rigid grate and movable furnace grate vertical view.

The burner hearth of embodiment is made of refractory material system tile (1), tile is outward the thermal insulation layer of anti-cellucotton the (2), thermal insulation layer to furnace shell (5) is a cavity, ring-shaped water jacket (4) is contained in the cavity middle part, and establish midfeather at the sealing ring that water jacket pushes up to the bell, make cavity become U-shaped exhaust gases passes (3), bell (7) is arranged at the top of stove, have water box (8), water box and water jacket all have water inlet pipe (9) and outlet pipe (10), the asbestos groove is arranged below the bell outer rim, interior dress asbestos seal ring (11), compress with the midfeather (12) that is contained in above the water jacket, make the exhaust gases passes envelope close, the structure of this stove, especially the structure of water jacket and installation site have ensured the fire box temperature height, can sufficient combustion, can fully absorb waste heat again, dissipation heat energy is few, has improved the thermal efficiency, and the burner hearth lower end is except that having rigid grate (13), also has movable furnace grate (14), take out movable furnace grate and can burn honeycomb briquette, the movable furnace grate of packing into can burn lump coal or other moulded coal, is heavy grey chamber (15) below the water jacket, ash removing opening (16) is established at its corresponding furnace shell position, is convenient to deashing.Make flue unimpeded, be convenient and use, put the shelf (17) that bell or cooker are used other also design of stove.

Claims

1, a kind of civil multifunctional high efficient heating furnace has burner hearth, water jacket and water box, it is characterized in that the U-shaped exhaust gases passes is arranged in the body; Water jacket is contained in the recess of U-shaped exhaust gases passes, between tile and the U-shaped gas flue thermal insulation layer is housed.

2, stove according to claim 1 is characterized in that the burner hearth lower end has rigid grate and movable furnace grate;

3, stove according to claim 1 and 2 is characterized in that below the water jacket heavy grey chamber being arranged, and there is ash removing opening at corresponding furnace shell position.
