Abstract

The utility model carries out two improvements on the structure of the exiting coal-burning warm bath boiler product. A boiler disc mouth is designed into a circular stage type boiler disc mouth which is provided with a lower inner stage, and the side of the boiler disc mouth (the upper mouth) is enlarged, and then the fire hanging height of the heating container is reduced. The inner wall of the burning chamber of the boiler body is welded with a plurality of rib fins, and then the heat absorbing area of the burning chamber is increased, and the heat efficiency of the boiler is improved.

Description

The efficient energy-saving coal-firing stove for heating and bathing

The utility model belongs to civilian heating stove and accessory technical field, relates to a kind of coal-fired stove for heating and bathing that can be used for family's cooking heating and health bathing aspect.

The coal-fired stove for heating and bathing of the comparatively general multi-purpose type of a kind of use is arranged in the market, and its version can be referring to Fig. 1.This stove for heating and bathing comprises the body of heater of band stove disc mouth 7, exhaust opening, cleanout door and an entery and delivery port 4,1, be provided with in the body of heater combustion chamber 9 and respectively with water inlet 4 and delivery port 1 in logical upper water box 6 and lower header 2, link up by several communicating pipes arranged side by side 3 between the upper and lower water tank 6,2.Because this coal-fired stove for heating and bathing also can directly provide bathing hot water to the user in for family's cooking heating, thereby it has many advances undoubtedly than traditional simple cooking heating type stove and accessory on structural principle.But the practical application structure of this stove for heating and bathing still also has 2 deficiencies, the bore of the stove disc mouth of this stove and accessory of the first less (φ=260 millimeter), cause cooker apart between furnace flame to hang fire highly higher, directly had influence on the cooking function of body of heater itself; It two is that effective endotherm area of combustion chamber is less relatively.

The purpose of this utility model is to overcome the existing in prior technology weak point, and a kind of modified efficient energy-saving coal-firing stove for heating and bathing that can further improve stove and accessory cooking function and energy-saving effect is provided.

For achieving the above object, the utility model designer has made following improvement to the structure of existing coal-fired stove for heating and bathing product: 1, stove disc mouth on the body of heater is designed to one has the ring step type stove disc mouth of inner step (also claiming two) down, the upper edge diameter of this stove disc mouth is 280～330 millimeters, the platform of following inner step is wide 20～30 millimeters, so strengthened the caliber size of stove stove disc mouth (suitable for reading), thereby reduced and had fiery height such as hanging of lower arcuate surface heating container such as frying pan etc., also can hang a concavity stone or metal plate for standing a stove on as a precaution against fire at the following inner step (two) of stove disc mouth in addition, thereby reduce platybasic type heating container such as pan, hanging of flat kettle etc. is highly fiery; 2, on combustion chamber of furnace body's inwall, be welded with a plurality of rectangular strip type fins,, improve the thermal efficiency in order to increase the combustion chamber endotherm area.

Below with reference to accompanying drawing the utility model content is elaborated.

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

Fig. 2 is the structural representation of the concavity bell that can hang on inner step under the stove disc mouth.

Fig. 3 is the structural representation of set fireguard in the stove.

As shown in the figure, the body of heater of this efficient energy-saving coal-firing stove for heating and bathing is made of upper water box 6, lower header 2, combustion chamber 9, stove disc mouth 7 etc., and the body of heater shell wall is provided with water inlet 4, delivery port 1 and exhaust opening and slag notch etc.The designed stove disc mouth 7 of the utility model structure is two ring step type stove disc mouths that have following inner step 71, and the upper edge diameter of stove disc mouth is 280～330 millimeters, and the last furnace port diameter of diameter that following inner step is 71 mouthfuls is little, is 260～300 millimeters.Under stove disc mouth, be hung with a concavity bell 8 on the inner step 71, the structure of this concavity bell 8 as shown in Figure 2, it is a circular product by the big up and small down second order platform of castiron section, on the following annular steps of concavity bell 8, can place pan, kettle class heating container, the fire that hangs of this type of heating container is highly reduced.The combustion chamber 9 that is used for burning coal is located in the body of heater, form a heat-conduction-type heat transfer structure, on 9 inwalls of combustion chamber, be provided with a plurality of ribs of making by the rectangle laths of metal 10, such structure has strong augmentation of heat transfer advantage, can fill out and increase endotherm area under the situation of coal volume effectively not increasing the combustion chamber, because existing coal-fired stove for heating and bathing chamber structure exists the restraining factors that endotherm area is difficult to enlarge, if increase the diameter or the height of combustion chamber, certainly will will cause increasing side effects such as filling out the coal amount, and the utility model has solved this problem preferably with the scheme that several fins 10 are welded in the combustion chamber inwall.In addition, in the enforcement thermal efficiency its cooking usefulness particularly that further improves body of heater, can in body of heater, be positioned at communicating pipes 3 anterior position places under the stove disc mouth and be placed with a semi-surrounding circular arc fireguard 5, can raise flame like this, flame can directly be washed on the heating container of pot, kettle class when flowing.Thermal convection current of the upper and lower water tank 6,2 of body of heater and communicating pipe 3 compositions, heat radiation type heat transfer structure had water instant heating function, can be used for preparing hot water, to satisfy the requirement of the daily bathing of family.

Compare with existing like product, the structure of coal-fired stove for heating and bathing described in the utility model is more rational, cooking reaches The thermal efficiency of heating is higher, use is convenient, energy-saving effect is also more obvious, and its product is best suited for vast Resident's domestic. applications in rural area and small towns is promoted.
