Technical Field

[0001] This application relates to the field of furnace enclosure technology, and in particular to a flue gas furnace enclosure. Background Technology

[0002] The fireplace, a traditional heating and cooking appliance, is widely used in outdoor camping, family gatherings, and winter heating. However, most existing fireplace designs are relatively simple, typically consisting of only a stove body and an area for placing fuel, lacking proper smoke extraction capabilities, which can cause inconvenience when used in enclosed winter environments.

[0003] Specifically, when using a hearth indoors, the smoke produced by combustion cannot be effectively expelled, often leading to a decline in indoor air quality and potentially harming human health. While ventilation can be used to remove smoke during warmer seasons like spring and summer, this method has limitations in the cold winter. Furthermore, the pervasive smoke indoors can obstruct vision and reduce the user experience. Therefore, existing hearths present numerous inconveniences when used indoors.

[0004] To address the aforementioned issues, a smoke extraction enclosure furnace is now designed. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] This application provides a smoke-venting fireplace that solves the problem that existing fireplaces in the related art usually do not have a smoke-venting function, making them inconvenient to use indoors.

[0031] Please see Figures 1-6A flue gas furnace includes: a furnace body 1 with an internal chamber; a fuel rack 2 for placing fuel inside the furnace body 1, the fuel rack 2 dividing the chamber into an upper combustion chamber and a bottom ash discharge chamber; a furnace surround 3 on the upper part of the furnace body 1, a flue gas duct 4 inside the furnace surround 3, a chimney 5 on the furnace surround 3 for discharging smoke from the flue gas duct 4; a fire-sealing cover 8 embedded in the furnace surround 3 for placing a kettle; a viewing door 6 hinged to one side of the furnace body 1; and an ash collection basin 7 inserted into the ash discharge chamber. The fuel rack has several through holes.

[0032] Users place fuels such as charcoal and coal on the feeding rack 2 inside the furnace body 1. The feeding rack 2 has several through holes to ensure air circulation, thereby supporting the complete combustion of the fuel.

[0033] The feeding rack 2 divides the furnace body 1 into an upper combustion chamber and a bottom ash discharge chamber. The combustion process takes place in the combustion chamber, and the resulting ash and unburned fuel fragments fall into the bottom ash discharge chamber.

[0034] The furnace body 1 has a flue duct 4 inside the furnace surround 3. When fuel burns in the combustion chamber, the generated smoke enters the flue duct 4 through the opening below the furnace surround 3, and the smoke in the flue duct 4 is finally discharged outward through the chimney 5 set on the furnace surround 3. The chimney 5 ensures that the smoke can leave the furnace surround smoothly and avoids lingering in the chamber.

[0035] The fire-sealing cover 8 is embedded in the surrounding tray 3 and can be used to place items such as kettles and teapots. The observation door 6 is hinged to one side of the furnace body 1, allowing users to easily observe the combustion and adjust the fuel. By opening the angle of the observation door 6, the flame size can also be adjusted to some extent.

[0036] The ash collection basin 7, inserted inside the ash discharge chamber, is used to collect the ash produced during combustion. When the ash accumulates to a certain level, the user can easily remove the ash collection basin 7 for cleaning.

[0037] Through the flue duct 4 and chimney 5 inside the furnace enclosure 3, this flue-exhausting furnace can efficiently expel the smoke generated during combustion to the outside, preventing smoke from lingering indoors and ensuring indoor air quality. The compact design of components such as the furnace body 1, the feeding rack 2, and the furnace enclosure 3 makes the overall structure of this flue-exhausting furnace compact and space-saving, suitable for use in limited indoor or outdoor spaces.

[0038] The design of the observation furnace door 6 and the fire-sealing cover 8 allows users to easily observe the combustion, adjust the fuel, and place items such as kettles, making operation simple and quick. The ash collection basin 7 inserted inside the ash discharge chamber allows users to easily remove and clean the ash, keeping the furnace area clean and hygienic.

[0039] In this embodiment, the furnace body 1 has an open top, and the furnace surround plate 3 is embedded in the top of the furnace body 1; two handles 9 are arranged opposite each other on the furnace body 1.

[0040] The upper part of the chamber of the furnace body 1 is designed to be open, allowing the furnace surround plate 3 to be embedded and securely installed above the chamber of the furnace body 1. The furnace surround plate 3 not only seals the opening of the furnace body 1, but also guides the smoke generated by combustion into the chimney 5 and finally exhausts it outdoors through the flue duct 4 opened inside it.

[0041] In addition, two handles 9 are provided opposite each other on the furnace body 1, allowing users to easily move the furnace by holding these two handles 9, making it convenient to adjust its position whether indoors or outdoors. At the same time, the handles 9 also provide additional support points when adding fuel, observing the combustion, or cleaning ash, making the operation more stable and safer.

[0042] In this embodiment, a rear observation window 10 is provided on the side of the furnace body 1 opposite to the observation furnace door 6.

[0043] A rear observation window 10 was added to the side of the furnace body 1 opposite to the observation door 6, which not only enriches the functionality of the furnace enclosure but also greatly enhances the user experience. The introduction of the rear observation window 10 allows users to clearly observe the combustion inside the furnace body 1 through the window on the other side without opening the observation door 6. This facilitates users in monitoring the fire and adjusting the fuel at any time.

[0044] Furthermore, the design of the rear observation window 10 also reflects consideration for user safety. During combustion, users can safely observe the fire without having to be close to the furnace body or open the furnace door, reducing the risk of burns or inhaling harmful fumes.

[0045] In one embodiment, the furnace enclosure 3 includes a cover plate 31 and a lower enclosure plate 32 connected to each other, the flue duct 4 is opened inside the lower enclosure plate 32, and the lower enclosure plate 32 is adapted to the opening above the chamber of the furnace body 1.

[0046] The cover plate 31, as the upper structure of the furnace surround plate 3, serves to seal and protect the opening of the furnace body 1 chamber.

[0047] The lower enclosure plate 32 is the core part of the furnace enclosure plate 3. It has a flue duct 4 inside, which allows the smoke generated by combustion to smoothly enter the flue duct 4 from the furnace body 1 chamber and finally be discharged outdoors through the chimney 5. The shape and size of the lower enclosure plate 32 are adapted to the opening above the chamber of the furnace body 1, ensuring that the furnace enclosure plate 3 can be tightly installed on the furnace body to prevent smoke leakage, and also to facilitate disassembly and cleaning.

[0048] Specifically, the cover plate 31 has a through hole, the fireproof cover 8 is embedded in the through hole, and the cover plate 31 has a material feeding area 312 for placing items.

[0049] The cover plate 31 is provided with an interface 311, which is used to connect the chimney 5 and is connected to the exhaust duct 4.

[0050] A through hole is specially provided on the cover plate 31 to accommodate the flame seal cover 8. The flame seal cover 8 is embedded in the through hole, which is not only secure and reliable but also convenient for users to access at any time. The main function of the flame seal cover 8 is to hold items such as kettles, and it also plays a role in adjusting the flame size and preventing smoke from escaping to a certain extent.

[0051] The food placement area 312 allows users to place food, tableware, or other small items directly on the stove, increasing its practicality and convenience.

[0052] Interface 311 is used to connect the chimney 5. It is connected to the exhaust duct 4 through interface 311, which ensures that the smoke can smoothly enter the chimney from the exhaust duct and finally be discharged outdoors.

[0053] Specifically, the lower enclosure 32 includes a rectangular frame plate disposed below the cover plate 31. One end of the rectangular frame plate is provided with a conical enclosure plate. The conical enclosure plate is hollow inside and connected to the rectangular frame plate in an open shape. The conical enclosure plate and the rectangular frame plate enclose each other to form a smoke exhaust duct 4.

[0054] The lower enclosure plate 32 is mainly composed of a rectangular frame plate located below the cover plate 31. This not only ensures the overall stability of the furnace enclosure plate 3, but also provides a basic framework for the formation of the flue duct 4. The size and shape of the rectangular frame plate are closely matched with the opening above the chamber of the furnace body 1, ensuring that the furnace enclosure plate 3 can be stably installed on the furnace body, while preventing the leakage of smoke.

[0055] At one end of the rectangular frame, a conical enclosure is specially provided. The enclosure is hollow inside and has an opening at its connection with the rectangular frame. This opening, together with the rectangular frame, encloses the main part of the exhaust duct 4. The conical enclosure not only optimizes the flow path of the smoke and reduces the resistance and turbulence of the smoke in the exhaust duct, but also enhances the smoke extraction effect.

[0056] In another embodiment, a second enclosing plate is also included. The second enclosing plate is formed by connecting a lower enclosing plate and a cover plate that are connected to each other. The lower enclosing plate is used to connect with the furnace body, and the cover plate has a through hole for placing the fire sealing cover 8. When used outdoors or in the warm spring and summer, the second enclosing plate can be used instead. Since no chimney is set, the flue gas is directly discharged and flows to the outside, making it more flexible to use.

[0057] In one embodiment, the fire-sealing cover 8 includes an outer disk embedded in a through hole in the cover plate 31, an inner disk embedded inside the outer disk, and a plurality of interconnected fire holes on both the outer disk and the inner disk, and a plurality of ring-shaped support legs on the inner disk.

[0058] The fire seal cover 8 mainly consists of two parts: an outer plate and an inner plate. Both parts are embedded in the through holes of the cover plate 31. The outer plate, as the external structure of the fire seal cover 8, serves to support and protect the inner plate, while also ensuring that the fire seal cover 8 can be securely installed on the cover plate 31.

[0059] The inner plate is the core part of the fire-sealing cover 8. The fire holes on it not only allow flames and heat to pass through, but also heat items such as kettles placed on the fire-sealing cover 8.

[0060] In addition, the inner plate is equipped with several ring-shaped support feet. These support feet not only provide a stable support surface for items placed on the fire-sealing cover 8, but the ring-shaped distribution of the support feet also ensures that the heat distribution on the fire-sealing cover 8 is more uniform, thus improving the heating efficiency.

[0061] In one embodiment, the chimney 5 includes a metal flexible hose connector, one end of which is connected to an exhaust pipe and the other end of which is connected to a connecting pipe, the other end of which is connected above the interface 311.

[0062] The chimney 5 mainly consists of three parts: a metal flexible hose connector, an exhaust pipe, and a connecting pipe. It not only ensures smooth smoke extraction but also provides sufficient flexibility and adaptability to meet the needs of different installation and usage scenarios.

[0063] One end of the metal flexible hose connector is connected to an exhaust pipe to guide the smoke generated inside the stove to the outside. The other end is connected to a connecting pipe to connect to interface 311 on the stove plate 3, ensuring that the smoke can smoothly enter the chimney 5.
