Abstract
Description
Technical Field
[0001] This application relates to the field of stove technology, specifically to the field of integrated wood-burning stove technology. Background Technology
[0002] With the development of modern kitchen design concepts, integrated, modular, and built-in kitchen appliances have become the mainstream trend. Traditional wood-fired stoves, due to their smoky flavor, still hold an irreplaceable position in specialty dining settings.
[0003] However, traditional wood-burning stoves mostly employ an open combustion structure and generally use top-mounted exhaust or direct chimney ventilation. Their exhaust paths occupy overhead space, resulting in an awkward overall appearance after installation, making it difficult to integrate with modern kitchen cabinets and affecting the overall aesthetics and space utilization of the kitchen. Furthermore, they conflict with range hoods in terms of duct layout, affecting both exhaust efficiency and safety hazards, further limiting their application in urban residences or integrated kitchens.
[0004] In response, some improved wood-burning stoves have attempted to introduce exhaust ducts, but they still lack systematic optimization in terms of combustion control, airflow organization, and exhaust path design, resulting in poor air intake and exhaust performance and making it difficult to integrate into the modern kitchen environment with integrated cabinet design. Summary of the Invention
[0005] In response to the aforementioned needs, this application proposes an integrated wood-fired stove, which aims to achieve the integration of the wood-fired stove with the overall kitchen cabinet by optimizing the design of the air intake and exhaust channels and the combustion system, thereby centrally discharging the flue gas generated by combustion through the bottom exhaust pipe.
[0006] To achieve the above objectives, the present application adopts the following technical solution:
[0007] This application proposes an integrated wood-burning stove, including a stove platform, a stove body disposed at the lower end of the stove platform, and a furnace core disposed in the stove body. The stove platform is provided with a stove opening that can cover the furnace core.
[0008] The furnace core includes a combustion chamber connected to the stove opening and an air inlet chamber and an air outlet chamber located at the lower end of the combustion chamber. The air inlet chamber is provided with an air intake port on the left and right sides and an exhaust fan connected to the air outlet chamber. The air outlet chamber is located at the rear end of the air inlet chamber.
[0009] In this way, by placing the air inlet and exhaust chambers at the lower end of the stove and using a fan to draw air from the exhaust chamber, the downdraft ventilation effectively avoids the space occupied by traditional exhaust structures above the kitchen, improving the compatibility of wood-burning stoves with integrated cabinets. At the same time, placing the exhaust chamber at the rear end of the air inlet chamber ensures that both ends of the air inlet chamber are open, providing sufficient oxygen for negative pressure combustion.
[0010] In some possible implementations, an air inlet pipe communicating with the stove chamber is provided on the outside of the air inlet cavity.
[0011] In some possible implementations, there are two air inlet pipes, which are respectively arranged on the left and right sides of the air inlet cavity.
[0012] In some possible implementations, the stove body also includes support feet located at the bottom of the stove body, with an air intake grille between the support feet.
[0013] In some possible implementations, a kick plate provided at the front end of the support leg is also included, the kick plate having a ventilation opening.
[0014] In some possible implementations, an exhaust pipe is also included located at the rear end of the exhaust chamber.
[0015] In some possible implementations, an exhaust pipe connecting the exhaust chamber and the stove chamber is also included.
[0016] In some possible implementations, a partition is also included to separate the air inlet duct from the air outlet duct.
[0017] In some possible implementations, a dust collection box is also included at the lower end of the air inlet cavity.
[0018] In some possible implementations, a door that is located at the front of the stove body and can be opened and closed is also included. Attached Figure Description

[0028] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art:
[0029] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the attached diagrams, while the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.
[0030] Furthermore, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.
[0031] Please refer to Figure 1 and Figure 2 This application discloses an integrated wood-fired stove, primarily designed for integration with kitchen cabinets. Therefore, one possible approach is to extend the exhaust duct from the lower rear end to the house's flue. One advantage of this lower extension is that it avoids the flue interface of traditional range hoods. A challenge in integrating an integrated wood-fired stove with kitchen cabinets is that the space on the left and right sides cannot accommodate the side air intake of traditional stoves. Therefore, a balanced exhaust and intake system is crucial.
[0032] Its overall appearance includes a stove platform 1 and a stove body 2 located at the lower end of the stove platform 1. The stove body 2 contains a furnace core, and the stove platform 1 has a stove opening that can cover the furnace core. A pot 100 can be placed on the stove opening (the attached drawing shows the pot 100 in the placed state, and the stove opening is not shown in the figure). At the front of the stove body 2, there is an openable and closable door 21, which is used to add firewood, clean up ashes, and start the fire.
[0033] Please refer to the reference. Figures 3 to 5 The furnace core includes a combustion chamber 3 connected to the burner opening, and an air inlet chamber 4 and an air outlet chamber 5 located at the lower end of the combustion chamber 3. Air inlets 41 and exhaust fans 6 connected to the exhaust chamber 5 are respectively located on the left and right sides of the air inlet chamber 4. Air entering through the air inlets 41 enters the combustion chamber 3 directly from bottom to top. An ash collection box 42 is located at the lower end of the inner cavity of the air inlet chamber 4. (Please refer to the reference.) Figure 6The lower part inside the door 21 is the ash collection box 42. In the middle of the stove 3, there is a bottom plate with a grid or mesh structure to prevent firewood from falling and also to achieve the effect of ash collection. This is a common technical means in the industry, and will not be described in detail.
[0034] Specifically, the exhaust chamber 4 is located at the rear end of the air inlet chamber 4, ensuring air intake on both the left and right sides of the air inlet chamber 4. Preferably, the exhaust chamber 5 has an L-shaped structure and can be arranged around a portion of the left side space of the air inlet chamber 4 to facilitate the installation of the exhaust fan 6. In this case, the exhaust fan 6 can be installed closer to the front, and a clearance area can be provided at the rear end of the exhaust chamber 5 for the installation of the smoke exhaust duct 61.
[0035] Please refer to reference 7 to 8. Figure 9 The secondary air intake and smoke exhaust within the combustion chamber 3 are described below. An air intake pipe 7 communicating with the combustion chamber 3 is provided on the outer side of the air intake cavity 4. There are two air intake pipes 7, located on the left and right sides of the air intake cavity 4 respectively. See reference [link / reference needed] for details. Figure 3 and Figure 5 The stove chamber 3 is provided with an inner shroud 31, and the firewood burns inside the inner shroud 31. The air inlet pipe 7 is provided on the outer periphery of the inner shroud 31. The bottom of the inner shroud 31 is provided with an air inlet channel, which can provide secondary oxygen supply to the firewood combustion through the air inlet channel at the lower end of the inner shroud 31.
[0036] Exhaust is achieved through the exhaust pipe 8 between the exhaust chamber 5 and the stove chamber, which is also located on the outer periphery of the inner enclosure 31. A partition 32 separates the air inlet pipe 7 and the exhaust pipe 8 on the outer periphery of the inner enclosure 31. An exhaust notch 33 extending outwards is located on the inner periphery of the partition 32. After the cookware 100 is placed, the generated smoke passes through the exhaust notch 33 and is exhausted by the suction of the exhaust fan 6 via the exhaust pipe 8. In practical applications, the bottom of the cookware 100 and the top of the stove chamber 3 are fitted together, including the top of the inner enclosure 31, thus forming a smoke passage between the cookware 100 and the partition 32, further enhancing the uniform side heating effect of the entire cookware 100. In some embodiments, an outer heat insulation plate 34 is also provided.
[0037] Please refer to Figure 2 The air intake structure of the integrated wood-burning stove is as follows: support legs 22 are provided at the bottom of the stove body 2, providing ventilation space at the bottom. Air intake grilles 23 are provided between the support legs 22 and are located on the left and right sides of the air intake cavity 4. At the same time, a kick plate 24 is provided at the front end of the support legs 22, and the kick plate 24 has ventilation openings 25.
[0038] Thus, by placing the air inlet chamber 4 and the exhaust chamber 5 at the lower end of the stove chamber 3, and using the exhaust fan 6 to draw air from the exhaust chamber 5, the downdraft ventilation effectively avoids the traditional top-mounted exhaust structure's occupation of kitchen ceiling space, improving the compatibility of the wood-burning stove with the overall kitchen cabinets. Simultaneously, placing the exhaust chamber at the rear end of the air inlet chamber ensures that both ends of the air inlet chamber are open, providing sufficient oxygen during negative pressure combustion.
[0039] As stated above, this case protects an integrated wood-burning stove, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
