Abstract

The utility model relates to an efficient energy-saving coal stove, comprising a stove chamber and a hot water tank surrounded with the stove chamber. The utility model is characterized in that the stove chamber is composed of a stove core connected with the stove chamber in a whole, a back fire inner ring, a back fire outer ring, a back fire pipe, a isolation plate of the water tank, a return pipe, a dedusting chamber and a stove door. Closed type combustion is implemented in the stove chamber. Secondary heating is implemented through the back fire pipe. The utility model has the advantages of high thermal efficiency, waste gas discharged outdoors, indoor little pollution, and high safety. A fusible safety device is added. High-temperature water on an upper layer is injected into a bottom layer through the return pipe. Thus, the balance of water temperature can be maintained. Hot water of a middle layer can be output. The temperature of the hot water is moderate. The amount of hot water supply is great. As long as fire is not extinguished in a range, cooking can be implemented at any time and hot water and shower can be supplied.

Description

Energy-efficient coal kitchen range

The utility model relates to a kind of solid-fuelled cooking stove, particularly a kind of energy-efficient coal kitchen range.

The various coal burning water heating cooking stoves that occur in the prior art just are provided with boiler or are added with heat pipe in addition in casees around burner hearth, and the thermal efficiency is low, and the hot water amount who provides is limited, and the water temperature imbalance.

The purpose of this utility model provides a kind of thermal efficiency height, the water temperature balance, and indoor exhaust air pollutes little, as long as not flame-out in the kitchen range, just can cook at any time, and the energy-efficient coal kitchen range of hot water and shower is provided.

Energy-efficient coal kitchen range of the present utility model comprises flue and surrounds the boiler of flue, it is characterized in that flue is made of the combustion chamber that is connected as a single entity, tempering outer ring, tempering inner ring, tempering tube, water tank baffle, return pipe, dirt pocket and fire door.

Fig. 1 is the utility model structural representation;

Fig. 2 is the flue tube structure schematic diagram;

Fig. 3 is the flue vertical view.

Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.

Boiler 1 casing that surrounds flue is made of shell 2, heat-insulation layer 3, liner 4, metal inner casing 5, box top left and right sides rear side is separately installed with hot water effluent's pipe joint 7 that cold water inlet joint 6, bottom stretch into cabinets cavity, tank floor is equipped with three-way connection 8, three-way connection 8 other two ends connect blowoff valve 9 respectively, meltable safeties 10 are installed, and there is feet 11 bottom surface for four jiaos.Combustion chamber 12 outsides have heat-conducting layer 13, metal shell 14 successively, there is the evagination base 15 that is connected with metal shell 14 upper end, be connected with tempering outer ring 16, tempering inner ring 17 on the evagination base 15, tempering outer ring 16 is higher than tempering inner ring 17, be equipped with collar 18 on the tempering outer ring 16 with the taper surface that matches at the bottom of the frying pan, there is the evagination fixed edge collar 18 upper ends, and the limit, lower end is stretched in the tempering inner ring 17, between collar 18 bottom surfaces and the limit, tempering inner ring 17 upper end the space are arranged.The dirt pocket 19 of being separated by with burner hearth is arranged at combustion chamber 12 bottoms, and dirt pocket 19 bottom surfaces are communicated with stretches out the dust flue joint 20 of tank floor.Metal shell 14 outsides are welded with water tank baffle 21, metal inner casing 5 welded seals of water tank baffle 21 peripheries and casing, after the arc tempering tube 22 of both sides passes water tank baffle 21, two-port is welded on tempering outer ring 16 respectively, on the dirt pocket 19 corresponding through hole limits, neighboring welded seal with water tank baffle 21 infalls, hot water effluent's infratubal port is welded on the through hole limit of water tank baffle 21, return pipe 23 places below the boiler 1 inner water tank dividing plate 21, one port is welded on the through hole limit of hot water outlet pipe with the water tank baffle 21 of forequarter, and the another port passes to place, hot water outlet pipe diagonal angle bottom.Other disposes the cover plate 24 of banking up a fire that bottom surface and collar 18 taper surfaces match.

The utility model is owing to adopt above design, and the taper surface and the bottom of a pan of collar 18 match, and heating surface area is big, is enclosed burning in the burner hearth, carries out the heating second time by inside and outside circle of tempering and tempering tube 22, has improved the thermal efficiency.The waste gas that produces during burning is discharged outdoor by dirt pocket 19, indoor exhaust air pollutes little, adds meltable safeties 10, and is safe and reliable.Water tank baffle 21 in the boiler 1 is except having the body of heater of reinforcing and inner support effect, when second time water filling, by the high-temperature water injection bottom of return pipe 23 with the upper strata, keep the water temperature balance, the middle level hot water that hot water outlet pipe's output temperature is moderate, available hot water amount is big, as long as it is not flame-out in the kitchen range, just can cook at any time, hot water and shower are provided, economical and practical.
