Abstract

The utility model belongs to a domestic heating furnace which both can be externally connected with a radiator for heating and can be used for daily life purposes such as heating water, cooking, bathing, etc., mainly comprising a furnace body, a furnace core, a water bag and a flue. The utility model is characterized in that the flue comprises an inner cavity and an outer cavity, the inner cavity is used as a flue outlet channel, and the outer cavity is communicated with the water bag. A spiral heat absorption pipe communicated with the water bag is arranged in the furnace body. A closed chamber is formed among the water bag, the outer cavity and the heat absorption pipe for containing heat exchange water. Heat quantity in the furnace body is directly absorbed by the heat absorption pipe, and simultaneously secondary heat absorption can also be processed by the outer cavity. The utility model has the effects of fast temperature rise, fast heat exchange and high heat efficiency.

Description

The domestic heating stove

The utility model belongs to the heating stove technical field, particularly a kind ofly utilizes honeycomb briquette to warm oneself and domestic heating stove that daily life is used.

Because the restriction of economic condition, the many places of northern China also do not solve the problem of central heating in winter, and especially in the rural area, the heating in winter generally is still the coal heating of single household, the heating weak effect.Existing home-use heating stove generally all is to convert on the basis of former honeycomb briquette stove, and its structure is around combustion chamber a water bag to be installed, and this water bag is provided with intake-outlet, can external radiator, be used for heating.For increasing heating effect, usually be in body of heater, to establish several combustion chambers more, can cook on the fire door, heat up water.But the most of heat in the heating stove of this structure, body of heater can not be absorbed by the water bag, but is dissipated by flue, and the thermal efficiency is low, causes much more coal-fired but the phenomenon of heating effect difference.

The purpose of this utility model is to provide a kind of quick heating, domestic heating stove that thermal absorptivity is high.

The utility model is achieved in that

The domestic heating stove, mainly form by body of heater, Shui Bao, combustion chamber and flue, the water bag be positioned at upper of furnace body around, the upper end that water wraps in combustion chamber forms fire door, it is characterized in that: be provided with the endothermic tube that is rotated into by helix tube near combustion chamber in the described body of heater, this endothermic tube communicates with the water bag of outside; Described flue is made up of inner and outer wall, the inner chamber that inwall internally forms be smoke outlet flue, inwall with outer wall between the exocoel that forms communicate with Shui Bao.

After the utility model adopted above structure, owing to set up endothermic tube in body of heater, the heat in the body of heater can directly absorb by endothermic tube and water bag, has increased endotherm area; Flue is made up of inside and outside wall simultaneously, and the cavity between the inside and outside wall communicates with Shui Bao, and the heat that distributes by flue is also absorbed effectively, prolonged flue gas flow, the heat major part of body of heater generation is utilized like this, has only small part to be dissipated, and the temperature of body of heater outside is no more than 100 ℃.Have heat exchange rapidly, quick heating, effect that the thermal efficiency is high.

Be provided with the endothermic tube of truncated cone simultaneously in the flue, make heat from the slit of endothermic tube, outwards to distribute, improved the heat utilization efficiency of stove.

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is a cross-sectional view of the present utility model shown in Figure 1;

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

In the accompanying drawing, 1 is that body of heater, 2 is that water bag, 3 is that combustion chamber, 4 is that smoke outlet flue, 5 is that exocoel, 6 is that the interior endothermic tube of body of heater, 7 is that the interior endothermic tube of smoke outlet flue, 8 is that delivery port, 9 is a water inlet.

As shown in Figure 1 and Figure 2, the utility model domestic heating stove mainly is made up of body of heater 1, combustion chamber 3, flue and water bag 2, and described combustion chamber 3 can be three, is neck and neck in the body of heater 1; Described water bag 2 is positioned at around the outside on body of heater 1 top, this water bag 2 surrounds the fire door of a circle on the top of combustion chamber 3, can be used for cooking on this fire door, heat up water etc., the diameter of the fire door that is surrounded by water bag 2 is less than the peripheral diameter of body of heater 1 but do not cover mouthful being advisable of combustion chamber 3.Described flue is made up of inner and outer wall, and the inner chamber that inwall internally forms communicates with the fire door place as smoke outlet flue 4; Form the exocoel 5 of a sealing between the inner and outer wall, this exocoel 5 communicates with water bag 2 inside.Be provided with delivery port 8 on the top of this exocoel 5, be provided with water inlet 9 in the bottom of water bag, can external radiator.Top in the body of heater 1 is provided with three endothermic tubes 6 near combustion chamber 3, is used to absorb heat; This endothermic tube 6 communicates with the water bag 2 of outside by suitable for reading and end opening; This endothermic tube 6 is to be formed by the helix tube rotation, to increase endotherm area.Bottom at combustion chamber 3 is provided with slag notch.Cavity in body of heater 1, combustion chamber 3 and the body of heater between the endothermic tube 6 can be filled seat clay.

Also be provided with an endothermic tube 7 that forms by the helix tube rotation in the described smoke outlet flue 4, this endothermic tube 7 be shaped as truncated cone, the cross section of bottom is little near the cross section on the inwall of smoke outlet flue 4, top, leaves certain space between each helix tube, is beneficial to the unimpeded of flue gas.Flue gas, heat in the smoke outlet flue 4 can only outwards distribute by the slit of helix tube like this, is beneficial to the absorption heat.Top, the bottom of the endothermic tube 7 in this smoke outlet flue communicate with exocoel 5 by external tapping respectively.

Form a chamber that communicates between endothermic tube 7 in the smoke outlet flue, the endothermic tube 6 in the body of heater and water bag 2, the exocoel 5, be used to hold the heat exchange water.

The quantity of the endothermic tube 6 in the body of heater also can be ordered in the body of heater 1 for more than three.

During use, honeycomb briquette is put into combustion chamber 3 internal combustion from fire door, and the endothermic tube 6 in the body of heater absorbs heats and heats exchange water in it, adds water in the hot water bag 2 by heat exchange, and hot water rises to exocoel 5, flows to radiator by delivery port 8.Simultaneously, flue gas and heat that stove produces outwards distribute by smoke outlet flue, because the effect of smoke outlet flue 4 inside spin shape endothermic tubes 7 has been carried out the secondary absorption to this part heat, are used to add hot water.Therefore can absorb most heat, simultaneously quick heating.
