[0001] The present invention relates to the technical field of stoves, and more particularly, to a stove capable of heating the stove top. Background Art

[0002] A coal stove is a common stove that uses coal and other fuels. Usually, the fuel is placed in the stove body for combustion. A stove top with through holes is placed at the upper end of the stove body. By placing the cooking utensil in the through hole above the stove top, the fuel in the stove body can be used to heat the cooking utensil. Moreover, the stove top can also be used as a table top. Therefore, it can not only be used for heating cooking utensils, but also as a dining table and a heating device.

[0003] Most of the heat of traditional coal stoves is used for heating cooking utensils, and the rest is used to heat the stove body for heating a certain range around. The remaining part is discharged through the exhaust pipe. There is insufficient heating for the stove top itself. During use, people come into contact with the stove top for a long time. The insufficient temperature of the stove top itself will to a certain extent affect the use experience of the stove. Therefore, a stove that can heat the stove top can be designed. Summary of the Invention

[0004] The purpose of the present invention is to provide a stove capable of heating the stove top, which can effectively utilize the heat generated by the combustion of fuel in the stove body to heat the stove top.

[0005] The present invention is realized through the following technical solutions: The stove capable of heating the stove top of the present invention includes a vertically arranged stove body, a horizontally arranged stove top with a hollow structure at the upper end of the stove body, and a heat conduction device arranged in both the stove body and the stove top; the stove body includes a vertically arranged outer cylinder, an inner cylinder arranged inside the outer cylinder and fixedly connected to the outer cylinder, and a support column arranged at the lower end of the outer cylinder; the heat conduction device includes a plurality of heating tubes vertically arranged between the outer cylinder and the inner cylinder, an exhaust pipe communicated with the upper end of the heating tube, and exhaust holes opened on the side wall of the exhaust pipe; the lower end of the heating tube is arranged below the outer cylinder, and the exhaust pipe is horizontally arranged inside the stove top.

[0006] Furthermore, the stove top includes an annular lower stove plate, an annular upper stove plate arranged above the lower stove plate, and a connecting plate for connecting the outer edge of the lower stove plate and the outer edge of the upper stove plate; the inner side of the lower stove plate is fixedly connected to the upper end of the outer cylinder; the exhaust pipe is arranged between the lower stove plate and the upper stove plate.

[0007] Furthermore, the height of the upper end surface of the inner cylinder is lower than the height of the upper end surface of the outer cylinder; the heating tube includes a first heat pipe, a second heat pipe, and a third heat pipe fixedly connected in sequence from top to bottom; the second heat pipe is arranged above the inner cylinder, and the second heat pipe is a spiral structure.

[0008] Furthermore, both the first heat pipe and the third heat pipe are straight pipes. The first heat pipe and the third heat pipe are coaxially arranged. The first heat pipe is rotatably connected to the exhaust pipe, and the axis of the first heat pipe is arranged close to the outer wall surface of the inner cylinder. A driving device is further included for driving the first heat pipe to rotate along its axis.

[0009] Furthermore, the driving device includes a lever horizontally arranged on the side wall at the lower end of the third heat pipe. A plurality of long strip-shaped through holes are formed in the side wall of the outer cylinder, and the lever passes through the through holes and extends outwards.

[0010] Furthermore, an annular support plate is arranged on the side wall at the lower end of the outer cylinder. An annular sliding plate is arranged above the support plate.

[0014] The technical solution of the present invention has at least the following advantages and beneficial effects: For the cooktop-heating stove of the present invention, when in use, fuel is placed in the inner cylinder and ignited, and then cookware to be heated can be placed on the cooktop for heating. During this process, the heat generated by the combustion of the fuel in the inner cylinder will also heat the heating pipes between the inner cylinder and the outer cylinder. After the inside of the heating pipes is heated, the high-temperature gas inside the heating pipes rises, enters the exhaust pipe, and is discharged from the exhaust holes of the exhaust pipe to heat the cooktop, so that the cooktop can also maintain a certain temperature. And heating the cooktop with hot air can effectively control the heating temperature and avoid excessive temperature. At the same time, cold air will be continuously sucked into the lower end of the heating pipe, and the cold air entering the heating pipe will be heated. Such a cycle is repeated. The high-temperature air discharged from the cooktop will be dissipated into the surrounding air, and the lower end of the heating pipe will absorb the cold air near the ground. In this way, the heat generated by the combustion of the fuel can be fully utilized, enabling it to radiate to a larger range. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0025] Embodiment

[0026] The following is further described in conjunction with specific embodiments. As shown in the attached Figure 1 - attached Figure 9As shown in the figure, the cooktop heating stove of this embodiment includes a vertically arranged stove body 10, a horizontally arranged cooktop 20 with a hollow structure at the upper end of the stove body 10, and a heat conduction device 30 arranged in both the stove body 10 and the cooktop 20; the stove body 10 includes a vertically arranged outer cylinder 11, an inner cylinder 12 arranged inside the outer cylinder 11 and fixedly connected to the outer cylinder 11, and a support column 13 arranged at the lower end of the outer cylinder 11; the heat conduction device 30 includes a plurality of heating tubes 31 vertically arranged between the outer cylinder 11 and the inner cylinder 12, an exhaust pipe 32 communicated with the upper end of the heating tube 31, and an exhaust hole 33 opened on the side wall of the exhaust pipe 32; the lower end of the heating tube 31 is arranged below the outer cylinder 11, and the exhaust pipe 32 is horizontally arranged inside the cooktop 20. Specifically, when in use, fuel is placed in the inner cylinder 12 and ignited, and then a pot or other utensils to be heated can be placed on the cooktop 20 for heating. During this process, the heat generated by the combustion of the fuel in the inner cylinder 12 will also heat the heating tubes 31 between the inner cylinder 12 and the outer cylinder 11. After the inside of the heating tube 31 is heated, the high-temperature gas inside the heating tube 31 rises, enters the exhaust pipe 32, and is discharged from the exhaust hole 33 of the exhaust pipe 32 to heat the cooktop 20, so that the cooktop 20 can also maintain a certain temperature. At the same time, the lower end of the heating tube 31 will continuously suck in cold air and heat the cold air entering the heating tube 31. This cycle continues, and the high-temperature air discharged from the cooktop 20 will be dissipated into the surrounding air, and the lower end of the heating tube 31 will absorb the cold air near the ground. In this way, the heat generated by the combustion of the fuel can be fully utilized and radiated to a larger range.

[0027] The cooktop 20 in this embodiment includes an annular lower cooktop plate 21, an annular upper cooktop plate 22 arranged above the lower cooktop plate 21, and a connecting plate 23 for connecting the outer edge of the lower cooktop plate 21 and the outer edge of the upper cooktop plate 22; the inner side of the lower cooktop plate 21 is fixedly connected to the upper end of the outer cylinder 11; the exhaust pipe 32 is arranged between the lower cooktop plate 21 and the upper cooktop plate 22.

[0028] The height of the upper end surface of the inner cylinder 12 in this embodiment is lower than the height of the upper end surface of the outer cylinder 11; the heating tube 31 includes a first heat pipe 311, a second heat pipe 312, and a third heat pipe 313 fixedly connected in sequence from top to bottom; the second heat pipe 312 is arranged above the inner cylinder 12, and the second heat pipe 312 is in a spiral structure. Specifically, the fuel mainly heats the spiral second heat pipe 312, and the spiral structure makes the overall length of the second heat pipe 312 longer and the heating effect better.

[0029] In this embodiment, both the first heat pipe 31 and the third heat pipe 313 are straight pipes. The first heat pipe 31 and the third heat pipe 313 are coaxially arranged. The first heat pipe 31 is rotatably connected to the exhaust pipe 32, and the axis of the first heat pipe 31 is arranged close to the outer wall surface of the inner cylinder 12. A driving device is further included for driving the first heat pipe 31 to rotate along its axis. Specifically, the first heat pipe 31, the second heat pipe 312, and the third heat pipe 313 can rotate, and the axis of the first heat pipe 31 is close to the inner cylinder 12. In this way, the heating temperature of the air in the second heat pipe 312 can be adjusted as needed. The specific principle is that when it is necessary to increase the heating temperature of the air in the second heat pipe 312, the first heat pipe 31 or the third heat pipe 313 can be rotated so that the second heat pipe 312 rotates with its side as the center of the circle and gradually rotates into the inner cylinder 12. At this time, the fuel can directly burn and heat the second heat pipe 312. The more the part of the second heat pipe 312 that enters the inner cylinder 12, the more obvious the heating effect and the higher the temperature (as shown in the attached Figure 5 figure). On the contrary, when it is necessary to reduce the heating temperature, the part of the second heat pipe 312 between the inner cylinder 12 and the outer cylinder 11 can be increased, or even all of it can be between the inner cylinder 12 and the outer cylinder 11 (as shown in the attached Figure 6 figure). In this way, the temperature of the stove top 20 can be adjusted according to actual needs.

[0030] The driving device in this embodiment includes a lever 34 horizontally arranged on the side wall of the lower end of the third heat pipe 313. A plurality of long strip-shaped through holes 14 are opened on the side wall of the outer cylinder 11, and the lever 34 passes through the through holes 14 and extends outwards. A ring-shaped support plate 15 is provided on the side wall of the lower end of the outer cylinder 11, and a ring-shaped sliding plate 16 is provided on the upper side of the support plate 15. A plurality of long strip-shaped sliding holes 17 are opened on the sliding plate 16. A slider 35 is provided on the lower side of the end of the lever 34 far from the third heat pipe 313, and the slider 35 is slidably arranged in the sliding hole 17. Specifically, by rotating the sliding plate 16, a plurality of levers 34 and the third heat pipe 313 can be driven to rotate simultaneously through the slider 35. Since the third heat pipe 313 is directly connected to the second heat pipe 312, the purpose of driving the second heat pipe 312 to rotate can be achieved.

[0031] The lower end of the third heat pipe 313 in this embodiment is rotatably connected to a support pipe 36, and the support pipe 36 is fixedly connected to the support column 13 through a support rod 37. Specifically, the third heat pipe 313 can be supported by the support pipe 36, and the cold air first enters the support pipe 36 and then enters the third heat pipe 313.

[0032] The exhaust pipe 32 in this embodiment is fixedly connected to the upper furnace plate 22 through a plurality of support blocks 25. Specifically, the exhaust pipe 32 can be fixed on the lower furnace plate 21 through the support plate 15.

[0033] A plurality of air discharge holes 24 are formed at the edge of the lower furnace plate 21 in this embodiment. Specifically, the hot air discharged from the exhaust pipe 32 enters the space between the lower furnace plate 21 and the upper furnace plate 22, heats the upper furnace plate 22 and the lower furnace plate 21, and then is discharged from the air discharge holes 24, so as to form a good air duct and promote the flow of hot air.

[0034] In summary, for the cooktop-heatable stove in this embodiment, when in use, the fuel is placed in the inner cylinder 12 and ignited, and then the cookware to be heated can be placed on the cooktop 20 for heating. During this process, the heat generated by the combustion of the fuel in the inner cylinder 12 will also heat the heating pipe 31 between the inner cylinder 12 and the outer cylinder 11. After the inside of the heating pipe 31 is heated, the high-temperature gas inside the heating pipe 31 rises, enters the exhaust pipe 32, and is discharged from the exhaust holes 33 of the exhaust pipe 32 to heat the cooktop 20, so that the cooktop 20 can also maintain a certain temperature. At the same time, the lower end of the heating pipe 31 will continuously suck in cold air and heat the cold air entering the heating pipe 31. Such a cycle is repeated, and the high-temperature air discharged from the cooktop 20 will be dissipated into the surrounding air, and the lower end of the heating pipe 31 will absorb the cold air near the ground. In this way, the heat generated by the combustion of the fuel can be fully utilized and radiated to a larger range.
