Description

Technical Field

[0001] This utility model relates to a heating stove, and more particularly to a civilian heating stove. Background Technology

[0002] Currently, most small residential heating stoves on the market have lids. Their working principle involves the lid covering the combustion chamber; it's opened when cooking or boiling water, and closed when not cooking or boiling. The fire then directly heats the lid. To prevent damage, a pot or kettle is placed on top to add water and boil. After the water boils, a large amount of steam is wasted. The only heat actually used for heating is the heat from the fire heating the side walls of the combustion chamber and the heat left behind by the fire passing through the flue. The heat released and absorbed in these two areas is far less than the heat released by the main flame, so most of the coal's heat is wasted. Furthermore, with the widespread use of kitchen appliances such as liquefied petroleum gas, rice cookers, and electric kettles, few people use stoves for cooking anymore. Therefore, existing stoves waste a significant amount of energy when used for heating. Summary of the Invention

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model discloses a heating furnace with a lidless structure, eliminating the need for a furnace cover. A furnace body sealing plate 5 seals the top surface of the furnace body 2, creating a medium cavity between the top surface of the furnace body 2 and the top surface of the combustion chamber 1. This allows all the heat generated in the combustion chamber 1 to be used for heating the medium, significantly improving the utilization rate of thermal energy. The heating medium can be water or air. The following sections will explain the use of either medium.

[0021] Example 1

[0022] like Figure 1-3As shown, this utility model discloses a heating stove, including a stove body 2. The side walls of the stove body 2 are enclosed by square panels, and a stove body sealing plate 5 is provided on the top surface of the stove body 2. The upper part of the rear wall of the stove body 2 is connected to a fume hood 7. A combustion chamber 1 is provided inside the stove body 2. The combustion chamber 1 is cylindrical, and a combustion chamber sealing plate 6 is provided on the top surface of the combustion chamber 1. The smoke hood 7 is equipped with a flue 10. The inner wall of the furnace body 2 and the top furnace body sealing plate 5 form a first medium cavity 12 between the furnace body 2 and the combustion chamber 1. The smoke hood 7 and the sides and top of the flue 10 form a second medium cavity 9. The first medium cavity 12 and the second medium cavity 9 are connected. One end of the flue 10 is inserted from the upper part of the rear wall of the furnace body 2 and connects with the upper part of the shell of the combustion chamber 1. The top surface of the flue 10 is higher than the height of the combustion chamber sealing plate 6, so that the flue gas in the flue flows more smoothly. The other end of the flue 10 extends out of the smoke hood 7, which makes it convenient for the extended flue 10 to be inserted into the kang (heated brick bed). The residual heat of the flue gas discharged from the flue 10 heats the kang.

[0023] Three medium pipelines 11 are installed in the flue 10, and the three medium pipelines 11 are arranged horizontally, parallel and equidistantly within the flue 10. Both ends of the medium pipelines 11 are connected to the second medium cavity 9. One end of the coal feeding channel 3 is inserted from the middle of the front wall of the furnace body 2 and connects to the shell of the combustion chamber 1. The coal feeding channel 3 makes an angle of 35 degrees with the horizontal direction. The other end of the coal feeding channel 3 is equipped with a furnace door 4. A medium inlet pipe 14 is provided at the lower part of the rear wall of the furnace body 2, and a medium outlet pipe 8 is provided at the top of the fume hood 7. Below the combustion chamber 1 is an ash chamber 15, and the bottom surface of the combustion chamber 1 is a grate 13. The ash chamber 15 is enclosed by a square shape by a surrounding plate 16. The front of the ash chamber 15 is an ash door 17. An air inlet regulating valve 18 is provided in the middle of the ash door 17, which can adjust the amount of air entering the ash chamber. After entering the ash chamber, the air enters the combustion chamber 1 through the grate 13 for combustion assistance. The bottom surface of the fume hood 7 and the bottom surface of the flue 10 are on the same horizontal plane, and the end face of the fume hood 7 is sealed at the connection with the flue 10 extending out of the fume hood 7.

[0024] In this embodiment, water is used as the medium. Water enters the first medium cavity 12 from the medium inlet pipe 14 and exchanges heat with the heat generated in the combustion chamber. The water flows upward in the first medium cavity 12 and flows into the second medium cavity 9. The medium pipeline 11 connects to the second medium cavity 9 and passes through the flue 10, which improves the heat exchange efficiency. Finally, the water is discharged from the medium outlet pipe 8 and sent to the heating pipeline. After circulation, it enters the medium inlet pipe 14 again. Coal is fed into the combustion chamber 1 through the coal feeding channel 3. The heat generated by the combustion in the combustion chamber 1 exchanges heat with the water in the first medium cavity 12. Since the first medium cavity is located between the combustion chamber sealing plate 6 at the top of the combustion chamber 1 and the furnace body sealing plate 5 at the top of the furnace body 2, the upward main flame of the combustion chamber 1 heats the water in the first medium cavity between the combustion chamber sealing plate 6 and the furnace body sealing plate 5, thereby improving the heat utilization rate. Part of the flame and flue gas generated by the combustion in the combustion chamber 1 enters the flue 10, and part of the flame and flue gas reheats the water in the second medium cavity 9 and the medium pipeline 11. Finally, the flue gas is discharged from the flue and enters the fire pit to heat the kang (heated brick bed) or is led out to the outside through the furnace tube.

[0025] Example 2

[0026] In Example 1, the medium is air. The diameters of the medium inlet pipe 14 and the medium outlet pipe 8 are increased. The medium inlet pipe 14 is connected to a flange, which is connected to a blower. The air enters the first medium cavity 12 from the medium inlet pipe 14 and exchanges heat with the heat generated in the combustion chamber 1. The hot air enters the second medium cavity 9 and the medium pipeline 11 and exchanges heat again with the flue gas in the flue 10. Finally, it is discharged from the thickened medium outlet pipe 8, which discharges hot air that can be used for heating. Everything else is the same as in Example 1.
