Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a multi-purpose boiler. Background Art

[0002] At present, household boilers are one of the more common heating devices in rural areas of northern China and are still widely used. Generally speaking, these boilers are used for heating. Their mechanism is generally to set a specific flue, and then set water tanks in the places where the flue passes, so as to heat the water by using the hot flue gas or flame, and use water and steam to achieve the purpose of heating.

[0003] However, the existing boilers have a single function and cannot well combine the heating and cooking functions, and their uses are single. Therefore, in view of this problem, a multi-purpose boiler is needed for improvement. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a multi-purpose boiler to solve the problems put forward in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A multi-purpose boiler includes a bottom plate. A top plate is arranged at the upper end of the bottom plate. A shell is fixedly arranged between the top plate and the bottom plate. In the middle of the inner side of the shell, there is a heating mechanism for heating water. The heating mechanism includes a heating steel pipe, a heating area, a smoke exhaust port, a water inlet pipe, and a water outlet pipe. A heating steel pipe is arranged in the middle of the inner side of the shell. The upper and lower ends of the heating steel pipe respectively penetrate through the top plate and the bottom plate. The heating steel pipe is welded and sealed to the bottom plate and the top plate. A heating area is arranged in the middle of the lower end of the bottom plate. A smoke exhaust port is arranged in the middle of the upper end of the top plate. A water inlet pipe is arranged on one side of the lower end of the shell. Water outlet pipes are fixedly arranged on both sides of the upper end of the top plate.

[0006] Preferably, a plurality of supporting feet are evenly and fixedly arranged around the lower end surface of the bottom plate. Through the supporting feet, the device can be conveniently erected on a fire source. When erecting, the middle of the heating area is aligned with the flame, so that the tongue of the flame can heat the middle of the lower end of the bottom plate, and the tongue of the flame can enter the heating steel pipe. Then, the hot flue gas can also be discharged through the heating steel pipe.

[0007] Preferably, an exhaust mechanism is provided on one side of the upper end of the top plate. The exhaust mechanism includes an exhaust pipe, exhaust holes, and a sealing cover. An exhaust pipe is fixedly provided on one side of the upper end of the top plate. A plurality of exhaust holes are evenly formed in the lower end of the outer surface of the exhaust pipe. A sealing cover is rotatably screwed onto the upper end of the exhaust pipe through threads. The purpose of designing the exhaust mechanism is as follows: Since water needs to be poured into the space between the interior of the housing and the heating steel pipe, if there is no exhaust mechanism, it is impossible to fill the interior of the housing with water when there is air inside. Initially, the sealing cover is opened by using the exhaust mechanism, and then water is poured into the interior of the housing through the water inlet pipe. When water overflows through the exhaust holes, it indicates that the interior of the housing is full of water at this time. Subsequently, the sealing cover is rotated through threads to move the sealing cover downward, and at this time, the sealing cover can be made to closely adhere to the outer surface of the top plate to seal the exhaust holes.

[0008] Preferably, anti-slip protrusions are provided on the outer surface of the sealing cover. The anti-slip protrusions can increase the friction coefficient of the outer surface of the sealing cover, thereby facilitating the rotation of the sealing cover to prevent slipping.

Among them, seven are for rural tile-roofed houses and thirteen are for buildings.

[0010] Preferably, the diameter of the housing is 28 cm.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. When heating the water inside the heating housing of the present utility model, since the flame and flue gas can enter the heating steel pipe, the contact area between the heating steel pipe and the water inside the housing can be significantly increased, improving the heating efficiency. At the same time, the waste heat generated at the upper end of the heating steel pipe can also be used for tasks such as warming rice and heating food, thus playing a multi-purpose role.

[0013] 2. The present utility model uses the exhaust mechanism to initially open the sealing cover, and then water is poured into the interior of the housing through the water inlet pipe. When water overflows through the exhaust holes, it indicates that the interior of the housing is full of water at this time. Subsequently, the sealing cover is rotated through threads to move the sealing cover downward, and at this time, the sealing cover can be made to closely adhere to the outer surface of the top plate to seal the exhaust holes.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a multi - purpose boiler, including a bottom plate 1, a top plate 2 is arranged at the upper end of the bottom plate 1, a housing 3 is fixedly arranged between the top plate 2 and the bottom plate 1, a heating mechanism for heating water source is arranged in the middle of the inner side of the housing 3, the heating mechanism includes a heating steel pipe 4, a heating area 5, a smoke exhaust port 6, a water inlet pipe 7, a water outlet pipe 8, a heating steel pipe 4 is arranged in the middle of the inner side of the housing 3, the upper and lower ends of the heating steel pipe 4 respectively penetrate through the top plate 2 and the bottom plate 1, the heating steel pipe 4 is welded and sealed with the bottom plate 1 and the top plate 2, a heating area 5 is arranged in the middle of the lower end of the bottom plate 1, a smoke exhaust port 6 is arranged in the middle of the upper end of the top plate 2, a water inlet pipe 7 is arranged on one side of the lower end of the housing 3, and water outlet pipes 8 are fixedly arranged on both sides of the upper end of the top plate 2.

[0021] A plurality of support feet 9 are evenly and fixedly arranged around the lower surface of the bottom plate 1. Through the support feet 9, it is convenient to mount the device on a fire source; when mounting, the middle of the heating area 5 is aligned with the flame, so that the tongues of the flame can scorch the middle of the lower end of the bottom plate 1 and can enter the heating steel pipe 4; then the scorching flue gas can also be discharged through the heating steel pipe 4;

[0022] One side of the upper end of the top plate 2 is provided with an exhaust mechanism. The exhaust mechanism includes an exhaust pipe 10, exhaust holes 11, and a sealing cover 12. One side of the upper end of the top plate 2 is fixedly provided with the exhaust pipe 10. A plurality of exhaust holes 11 are evenly formed in the lower end of the outer surface of the exhaust pipe 10. The upper end of the exhaust pipe 10 is movably screwed with the sealing cover 12 through threads. The purpose of the design of the exhaust mechanism is as follows: Since water needs to be poured into the space between the interior of the housing 3 and the heating steel pipe 4, if there is no exhaust mechanism, it is impossible to fill the interior of the housing 3 with water when there is air inside. Initially, the sealing cover 12 is opened by using the exhaust mechanism, and then water is poured into the interior of the housing 3 through the water inlet pipe 7. When the water overflows through the exhaust holes 11, it indicates that the interior of the housing 3 is full of water at this time. Subsequently, the sealing cover 12 is rotated through threads to move the sealing cover 12 downward. At this time, the sealing cover 12 can be made to closely adhere to the outer surface of the top plate 2 to seal the exhaust holes 11.

[0023] Anti-slip protrusions are provided on the outer surface of the sealing cover 12. The anti-slip protrusions can increase the friction coefficient of the outer surface of the sealing cover 12, thereby facilitating the rotation of the sealing cover 12 to prevent slipping.

[0024] A plurality of heating steel pipes 4 are provided and are evenly spaced in a ring shape in the middle of the heating area 5. The multiple heating steel pipes 4 of the present device can significantly increase the contact area between the heating steel pipes 4 and the water inside the housing 3. The number of heating steel pipes 4 can be freely selected in different usage environments. 7 or 13 heating steel pipes can be used. Among them, 7 are suitable for rural tile houses, and 13 are suitable for buildings.

[0025] The diameter of the housing 3 is 28 cm.

[0026] Working principle: Before using this device, the pipes should be connected first. When connecting the pipes, the water inlet pipe 7 is responsible for injecting water into the interior of the housing 3 and is also responsible for the circulation of the heating water during subsequent heating. The outlet pipe 8 is responsible for discharging the heating water.

[0027] When using this device, the device can be conveniently erected on the fire source through the support feet 9. When erecting, the middle of the heating area 5 is aligned with the flame, so that the tongue of the flame can scorch the middle of the lower end of the bottom plate 1 and the tongue of the flame can enter the heating steel pipe 4. Subsequently, the scorching flue gas can also be discharged through the heating steel pipe 4. In this way, when heating the water inside the housing 3, since both the flame and the flue gas can enter the heating steel pipe 4, the contact area between the heating steel pipe 4 and the water inside the housing 3 can be significantly increased, improving the heating efficiency. At the same time, the waste heat generated at the upper end of the heating steel pipe 4 can also be used for cooking rice, heating food, etc.

[0028] In this device, since water needs to be filled in the space between the inside of the housing 3 and the heating steel pipe 4, if there is no exhaust mechanism, it is impossible to fill the inside of the housing 3 with water when there is air inside. By using the exhaust mechanism, the sealing cover 12 is initially opened, and then water is filled into the inside of the housing 3 through the water inlet pipe 7. When the water overflows through the exhaust hole 11, it indicates that the inside of the housing 3 is filled with water at this time. Subsequently, the sealing cover 12 is rotated downward through the thread so that the sealing cover 12 can be closely attached to the outer surface of the top plate 2 to seal the exhaust hole 11.
