Description

Technical Field

[0001] This invention relates to the field of combustion furnace technology, specifically to a combustion exhaust assembly and a combustion furnace. Background Technology

[0002] In daily life or when people go camping in the wild, they often use wood-burning stoves for grilling, cooking and other operations. These stoves mainly utilize the chimney effect, that is, the high temperature generated by combustion raises the temperature of the gas inside the stove and the upper part of the inner liner, creating a pressure difference between the inside and outside of the stove. This causes the hot air inside the stove to rise, while the cold air outside is drawn into the stove through the air inlet, creating a circulating airflow inside and outside the stove, which in turn allows the fuel inside to burn.

[0003] In existing combustion furnaces, some have built-in ash collection trays, but the ash collection trays can only be removed after the combustion chamber is taken out for ash emptying and cleaning. Furthermore, the combustion chamber and ash collection trays must be reassembled when the furnace is reused, which is very inconvenient. In addition, the combustion chamber must have separate positioning structures for the combustion chamber and ash collection trays, which is complex and costly, and urgently needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to address the deficiencies and shortcomings of the prior art by providing a combustion exhaust assembly and a combustion furnace that can at least solve one of the aforementioned problems and has the advantage of convenient ash removal.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a combustion exhaust assembly, comprising:

[0006] Combustion exhaust body;

[0007] A connector, the upper end of which is connected to the lower surface of the combustion chamber body; and

[0008] The ash receiving tray has its upper surface connected to the lower end of the connector.

[0009] The present invention further provides that the combustion exhaust body is provided with a plurality of through holes, and the plurality of through holes are all located directly above the ash receiving tray, so that the ash can fall into the ash receiving tray.

[0010] In a further embodiment of the present invention, the combustion exhaust body, the connecting member, and the ash receiving tray are integrally formed.

[0011] In a further embodiment of the present invention, the ash receiving tray is detachably connected to the combustion exhaust body via the connector.

[0012] The present invention further provides that the connecting member includes: an external threaded post disposed on the lower side of the middle portion of the combustion exhaust body, and an internal threaded post disposed on the upper side of the middle portion of the ash receiving tray; the ash receiving tray is detachably assembled on the lower side of the combustion exhaust body through the cooperation of the internal threaded post and the external threaded post.

[0013] The present invention further includes a carrying device provided in the middle of the upper surface of the combustion exhaust body.

[0014] In a further embodiment of the present invention, the carrying device is a lifting ring.

[0015] To achieve the above objectives, another technical solution adopted by the present invention is: a combustion furnace, comprising: a combustion furnace body, and a combustion exhaust assembly as described above disposed within the combustion furnace body.

[0016] The present invention further provides that the inner wall of the combustion furnace body is provided with a raised ring or multiple support points; the combustion exhaust assembly is mounted on the raised ring or multiple support points inside the combustion furnace body through the combustion exhaust body.

[0017] The invention further includes, in this embodiment, a liquid fuel container mounted on the upper side of the combustion furnace body for holding liquid fuel.

[0018] After adopting the above technical solution, the beneficial effects of the present invention are as follows: In the present invention, the ash receiving tray is hoisted on the lower side of the combustion chamber body by means of the connector, so that when the combustion chamber body is taken out, the ash receiving tray will also be taken out at the same time, which makes it easier to empty the ash and clean the ash receiving tray, and is more convenient to use; and when this structure is used in the entire combustion furnace, there is no need to set a corresponding positioning structure for the ash receiving tray in the combustion furnace, which makes the furnace body structure simpler and reduces costs.

Detailed Implementation

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.

[0033] This embodiment relates to a combustion exhaust assembly, such as... Figures 1-2As shown, the assembly includes: a combustion chamber body 100, a connector 200, and an ash collection tray 300. The upper end of the connector 200 is connected to the lower surface of the combustion chamber body 100, and the lower end is connected to the upper surface of the ash collection tray 300. The combustion chamber body 100 has multiple through holes 110, all located directly above the ash collection tray 300, allowing ash to fall into the tray. In this embodiment, the through holes 110 are circular; in other embodiments, they can be elongated, rectangular, elliptical, triangular, etc. The combustion chamber body 100 is used to hold solid fuels such as wood and charcoal, while the ash collection tray 300 is used to collect ash. When solid fuels burn, the resulting ash falls into the ash collection tray 300. In this embodiment, the combustion chamber body 100 is rectangular with rounded corners; in other embodiments, it can be circular. Furthermore, the combustion chamber body 100 can also be grid-shaped.

[0034] In this embodiment, the ash receiving tray 300 is detachably connected to the combustion exhaust body 100 via the connector 200.

[0035] Specifically, such as Figure 2 As shown, the connector 200 includes: an externally threaded post 210 disposed on the lower side of the middle portion of the exhaust body 100, and a screw-mounted post 220 disposed on the upper side of the middle portion of the ash collection tray 300; the ash collection tray 300 is assembled on the lower side of the exhaust body 100 through the cooperation of the externally threaded post 210 and the screw-mounted post 220. To make the assembly more secure, a wing nut (not shown) is used to lock the end of the externally threaded post 210 that extends out of the ash collection tray 300. The screw-mounted post 220 may have a corresponding internal thread. In other embodiments, the connector 200 may also have other specific structures to allow the ash collection tray 300 to be detachably connected to the exhaust body 100; for example, the connector 200 may be divided into two sections, one section disposed on the lower side of the exhaust body 100 and the other section disposed on the upper side of the ash collection tray 300, one section being a male thread and the other a female thread.

[0036] In one embodiment, the combustion exhaust body 100, the connector 200, and the ash collection tray 300 are integrated into one unit.

[0037] In one embodiment, the connector 200 is fixedly connected to the combustion exhaust body 100 and the ash receiving tray 300.

[0038] like Figure 1As shown, a lifting device is provided in the middle of the upper surface of the combustion chamber body 100. This lifting device makes it easier to pick up and put down the combustion chamber assembly, whether operated with one hand or with a tool, and ensures that the hands are kept away from the inner wall of the combustion furnace, thus enhancing safety. Furthermore, the lifting device also allows for the overlapping of solid fuels such as wood strips and coal. During overlapping, one end of the wood strip or coal overlaps the lifting device, and the other end overlaps the combustion chamber body 100, ensuring that the multiple through holes 110 on the combustion chamber body 100 are not blocked by solid fuel, allowing sufficient air to enter and aiding in the combustion of the solid fuel.

[0039] In this embodiment, the carrying device is fixedly mounted on the exhaust pipe body 100. Specifically, the carrying device is welded to the exhaust pipe body 100 via an intermediate component. In other embodiments, the carrying device may be fixed to the exhaust pipe body 100 using other methods or structures.

[0040] In other embodiments, the carrying device may also be detachably mounted on the exhaust body 100.

[0041] The carrying device can take many forms; specifically in this embodiment, such as... Figure 1 As shown, the carrying device is a lifting ring 400. The ring-shaped structure allows the user to easily lift it by hand, or to hook it with a tool for lifting. In other embodiments, the carrying device can be a hook, i.e., a ring with an opening. In other embodiments, the carrying device can also be a handle, a handle, etc.

[0042] The ash collection tray 300 is hoisted to the underside of the combustion chamber body 100 via the connector 200. This allows the ash collection tray 300 to be removed along with the combustion chamber body 100, making it easier to empty and clean the ash collection tray 300 and improving its usability. Furthermore, when this structure is used throughout the combustion furnace, there is no need to install a corresponding positioning structure for the ash collection tray 300 within the combustion furnace body 500, simplifying the furnace structure and reducing costs. Additionally, the combustion chamber body 100 is equipped with a lifting device, which makes it easier to pick up and put down the combustion chamber components. This lifting device can also provide oblique support for solid fuel combustion, which is beneficial for its combustion.

[0043] like Figures 1-2 As shown, a through hole is provided in the middle of the exhaust body 100. The head end of the connector is located on the upper side of the exhaust body 100, while the other part of the connector passes through the through hole and is located on the lower side of the exhaust body 100. Specifically, the connector is a bolt, and a hollow mounting post with internal threads is provided on the ash receiving tray. The threaded part of the bolt passes through the through hole of the exhaust body 100 and is threadedly connected to the mounting post. A carrying device is fixedly mounted on the head end of the bolt.

[0044] This embodiment also relates to a combustion furnace, such as Figures 3-5 As shown, it includes: a combustion furnace body 500, and a combustion exhaust assembly as described above disposed within the combustion furnace body 500.

[0045] like Figure 5 and Figure 7 As shown, a raised ring 521 is provided on the inner wall of the combustion furnace body 500, and the combustion exhaust body 100 is mounted on the raised ring 521 inside the combustion furnace body 500, so that the ash receiving tray 300 is suspended inside the combustion furnace body 500. In other embodiments, the inner wall of the combustion furnace body 500 can also be provided with multiple support points (not shown), and the combustion exhaust body 100 can also be mounted on multiple support points.

[0046] When the combustion chamber body 100 is placed on the convex ring 521 or multiple support points, the ash receiving tray 300 is suspended inside the combustion furnace body 500, with gaps between it and the inner wall and bottom wall of the combustion furnace body 500. This significantly reduces the heat transfer efficiency of the heat source conducted through the ash receiving tray 300 or the heat source on the ash receiving tray 300. Compared with existing combustion furnaces, this effectively reduces the temperature of the outer wall and bottom of the combustion furnace body 500.

[0047] To further reduce the temperature at the contact point between the combustion furnace body 500 and the ground, such as Figure 5 and Figure 6 As shown, a downwardly protruding support portion 511 is provided in the middle of the bottom surface of the combustion furnace body 500. Since the support portion 511 is farther away from the heat source, the temperature on the support portion 511 will be lower.

[0048] Based on this, similarly Figure 5 and Figure 6 As shown, a heat insulation pad 512 is provided on the lower side of the support 511. The temperature of the lower surface of the heat insulation pad 512 is obviously lower. When the combustion furnace is placed directly on a table or lawn, the scorching of the table or lawn is weaker.

[0049] like Figures 3-7 As shown, the combustion furnace body 500 includes: an outer furnace body 510 with a support 511, and an inner furnace body 520 disposed within the outer furnace body 510 and suspended in the air. The suspended suspension of the inner furnace body 520 means that the outer side wall of the inner furnace body 520 and the inner side wall of the outer furnace body 510 are separated by space and do not directly contact each other, and the outer bottom wall of the inner furnace body 520 and the inner bottom wall of the outer furnace body 510 are also separated by space and do not directly contact each other. This double-layer furnace design, with the heat source located within the inner furnace body 520, results in lower temperatures on the outer side wall and outer bottom wall of the outer furnace body 510.

[0050] In this embodiment, as Figure 5 and Figure 6As shown, external air inlets 513 are provided on both the periphery of the support portion 511 and the bottom side of the outer furnace body 510, specifically on the periphery of the support portion 511. In other embodiments, the external air inlet 513 may be provided at only one location. In some embodiments, the external air inlet 513 may also be located on the periphery of the outer furnace body 510, near the lower part. Figure 7 As shown, the bottom of the inner furnace body 520 is provided with an internal bottom air inlet 522. External air enters the inner side of the inner furnace body 520 in sequence through the external air inlet 513, the gap between the bottom of the outer furnace body 510 and the inner furnace body 520, and the internal bottom air inlet 522.

[0051] In this embodiment, as Figures 3-7 As shown, an internal sidewall ventilation hole 523 is provided near the upper part of the inner furnace body 520. External air also enters the inner furnace body 520 sequentially through the external air inlet 513, the gap between the outer furnace body 510 and the sidewall of the inner furnace body 520, and the internal sidewall ventilation hole 523. This airflow arrangement allows the flame inside the furnace to achieve a secondary combustion effect at the height of the internal sidewall ventilation hole 523, resulting in a better flame effect.

[0052] like Figures 8-9 As shown, the combustion furnace also includes a liquid fuel container 600 mounted on the upper side of the combustion furnace body 500 for holding liquid fuel. Here, liquid fuel refers to liquid alcohol, etc. When the user selects to use the combustion furnace body 100, the liquid fuel container 600 is removed; when the user selects to use the liquid fuel container 600, it is not necessary to remove the combustion furnace body 500.

[0053] In this embodiment, as Figures 8-10 As shown, the liquid fuel container 600 includes a liquid combustion plate 610 mounted on the upper side of the combustion furnace body 500 and a liquid combustion cover 620 covering the upper side of the liquid combustion plate 610. The liquid combustion plate 610 has a space in its center for holding the liquid fuel. The liquid combustion cover 620 provides a certain flame-concentrating effect. Preferably, the liquid combustion plate 610 and the liquid combustion cover 620 are designed separately, meaning the liquid combustion cover 620 can be lifted relative to the liquid combustion plate 610; of course, the liquid combustion plate 610 and the liquid combustion cover 620 can also be designed with a fixed connection or be integrally formed; alternatively, only the liquid combustion plate 610 can be provided without the liquid combustion cover 620.

[0054] Specifically, such as Figure 10 As shown, the liquid combustion pan 610 includes a pan body 611 and a combustion pan outer edge 612. The pan body 611 has a certain height to give it sufficient volume; the combustion pan outer edge 612 is disposed around the pan body 611 and is used to overlap the upper edge of the combustion furnace body 500 to mount the pan body 611 on the upper side of the combustion furnace body 500.

[0055] As a preferred option, such as Figure 10 As shown, a carrying structure is provided on the outer edge 612 of the combustion disc. Specifically, in this embodiment, the carrying structure is an arc-shaped protrusion 613 provided on the edge of the outer edge 612 of the combustion disc; in other embodiments, the carrying structure may also be provided as a handle, etc.

[0056] Similarly, Figure 10 As shown, a first maximum liquid level line 614 is provided on the inner wall of the disc 611 to remind the user not to add excessive liquid fuel and to ensure safety. To facilitate the user's accurate understanding of the amount of liquid fuel added, a scale line can also be provided on the inner wall of the disc 611.

[0057] Similarly, Figure 10 As shown, the inner wall of the disc 611 is inclined so that the upper cross-sectional area of ​​the disc 611 is larger than its lower cross-sectional area. This design, with the disc 611 being larger at the top and smaller at the bottom, makes it easier to pour in liquid fuel and also helps improve combustion efficiency. In embodiments without a liquid combustion cap 620, the upper surface of the disc 611 is configured with an area slightly smaller than the bottom area of ​​the kettle, so that the kettle can be placed directly on the liquid combustion disc 610 for heating.

[0058] like Figure 10 As shown, the liquid combustion cover 620 includes a wall 621 and an outer edge 622. The wall 621 is circumferentially closed, with openings at both the top and bottom. The outer edge 622 is located around the wall 621 and is used to overlap the liquid combustion plate 610, thus suspending the wall 621. Because the wall 621 is suspended and open at the bottom, the liquid fuel between the liquid combustion plate 610 and the wall 621 flows with the liquid fuel inside the wall 621.

[0059] Based on this, an inner ring 623 is provided between the outer edge 622 of the combustion cover and the wall 621, and a ring of vent holes 624 is provided on the top of the inner ring 623. When the liquid fuel burns in the liquid fuel container 600, part of the liquid is vaporized. The vaporized liquid fuel is re-burned when it passes through the ring of vent holes 624, which enhances the flame combustion effect around the wall 621, thereby making the heating effect more uniform.

[0060] The disc body 611 of the liquid combustion disc 610 is similar, such as Figure 10 As shown, a second maximum liquid level line 625 is provided on the inner wall of the liquid combustion cap 620, body 621, to remind the user not to add excessive liquid fuel and to ensure safety. To facilitate accurate understanding of the amount of liquid fuel added, graduation lines can also be provided on the inner wall of the disc 611.

[0061] The disc body 611 of the liquid combustion disc 610 is similar, such as Figure 10As shown, the inner wall of the liquid combustion cap 620's wall 621 is inclined so that the upper cross-sectional area of ​​the wall 621 is larger than its lower cross-sectional area. This design, with the wall 621 being larger at the top and smaller at the bottom, makes it easier to pour in liquid fuel and also helps improve combustion efficiency. The upper surface of the wall 621 is designed with an area slightly smaller than the bottom area of ​​the kettle, so that the kettle can be placed directly on the liquid combustion cap 620 for heating.

[0062] The system includes a combustion chamber 100 and a liquid fuel container 600. When using the combustion chamber 100, solid fuel can be added to it for combustion. When using the liquid fuel container 600, liquid fuel can be added to it for combustion. Since solid fuel combustion is more suitable for grilling and similar activities, while liquid fuel combustion is more suitable for boiling water, users can choose between solid and liquid fuel based on their preferences and usage scenarios.

[0063] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
