[0041] This embodiment provides an outdoor heat-insulating stove, as shown in the attached image. Figure 1 ~Appendix Figure 5 As shown, the furnace includes a furnace body 1 with an inner cavity a, and an exhaust pipe 2 disposed on the outer wall of the furnace body 1 and communicating with the inner cavity a.
[0042] The furnace body 1 is generally formed by connecting four plates and a bottom plate, with an open top and an internal cavity a; the exhaust pipe 2 is installed on one of the side plates for exhausting smoke. The open part at the top of the furnace body 1 is used to connect with accessories, such as a closed cover or a cooking rack, etc. These commonly used accessories are existing technologies, so they will not be described in detail in this embodiment.
[0043] In this embodiment, the furnace body 1 is provided with a fuel port 11 communicating with the inner cavity a on the side wall connected to the flue pipe 2, and a feeding box 3 that can cover the fuel port 11 is also connected to the side wall of the furnace body 1 where the fuel port 11 is provided; the feeding box 3 includes a box body 31 and a control board 32.
[0044] The box body 31 has at least one storage cavity b and a discharge port 311 that matches the fuel port 11 and communicates with the storage cavity b;
[0045] The control board 32 is located at the discharge port 311 and moves along the first direction D1 or the opposite direction of the first direction D1 by means of sliding connection with the box body 31.
[0046] Furthermore, when the control plate 32 moves to its limit position along the first direction D1, the projection of the control plate 32 on the side wall of the furnace body 1 where the fuel port 11 is located covers the projection of the discharge port 311.
[0047] Wherein, the first direction D1 is a direction perpendicular to the first direction or the direction of gravity, the second direction D2 is a direction perpendicular to the first direction D1, and the third direction D3 is a direction perpendicular to both the first direction D1 and the second direction D2. The length of the fuel inlet 11 is distributed along the third direction D3, and the height is distributed along the first direction D1. The length of the fuel inlet 11 is at least 1 / 2 or more of the length of the side wall of the furnace body 1, and the height is at least 1 / 3 or more of the height of the side wall of the furnace body. This arrangement facilitates the feeding of fuel into the furnace body 1 through the fuel inlet 11. The size of the discharge port 311 is preferably larger than that of the fuel inlet 11. The box body 31 is preferably a box body with an open side, which is formed by connecting five plates. The open side is attached to the outer side wall of the furnace body 1 to form a closed storage cavity b. At this time, the open side is the discharge port 311. The control plate 32 is slidably connected to the discharge port 311, and its area is larger than that of the fuel inlet 11, ensuring that the control plate 32 can completely close the fuel inlet 11 to prevent fuel from entering the fuel inlet 11 through the discharge port 311. Preferably, the control plate 32 slides against the outer wall of the furnace body 1 to improve tightness. By sliding the control plate 32 along the first direction D1 or the opposite direction of the first direction D1, the connection area between the fuel port 11 and the discharge port 311 can be reduced or even locked or expanded, thereby controlling the total amount of solid fuel entering the furnace body 1 from the box 31. This achieves the purpose of adding solid fuel into the furnace body 1 without the risk of burning or dirt during the middle of combustion, effectively controlling the combustion intensity and combustion process, and ensuring that the furnace has the advantages of good stability, strong heat retention, and easy control.
[0048] As some preferred embodiments, the control panel 32 has a first extension 321 protruding from the housing 31, and the housing 31 is provided with a strip hole 312 through which the first extension 321 passes; when the control panel 32 moves to the limit position along the first direction D1, the first extension 321 protrudes from the furnace body 1.
[0049] The first extension 321 is designed to protrude from the upper surface of the furnace body 1 even when the control panel 32 is at its lowest point (extreme position). This serves two purposes: first, to provide wind and dust protection; and second, to facilitate controlling the pulling process of the control panel 32 while minimizing the risk of burns when the first extension 321 is far from the heat source. Furthermore, a first handle 323 is provided on the surface of the first extension 321 furthest from the furnace body 1 to enhance convenience.
[0050] Furthermore, a fireproof layer 322 is provided on the surface of the control panel 32 near the fuel inlet 11. The fireproof layer can be made of materials known to have fire-retardant properties, such as asbestos, thus reducing the risk of spontaneous combustion of solid fuel within the container 31. Furthermore, the bottom surface of the container 31 is inclined, and the height of the end near the feeding port 313 is greater than the height of the end near the discharge port 311. This arrangement facilitates the fixing of fuel as it slides into the feeding port 313, helping to increase the feeding speed and also reducing the risk of flames entering the container 31.
[0051] In this embodiment, the box body 31 also has a feeding port 313 that is opposite to the discharge port 311 and communicates with the storage cavity b, and a sealing door 314 that is rotatably connected to the side wall of the box body 31 to close the feeding port 313. This arrangement facilitates the addition of a fixed amount of fuel into the box body 31. The sealing door and the feeding port 313 can adopt any convenient hinge structure in the prior art, so it will not be described in detail.
[0052] In this embodiment, an ash collection box 4 is slidably connected to the bottom surface of the furnace body 1, and a discharge port 12 is provided on the side wall of the furnace body 1 for the ash collection box 4 to pass through. The ash collection box, as the name suggests, is a box for collecting combustion ash. The box is open at the top, and its bottom surface is attached to the bottom surface of the furnace body 1 and can slide. When there is a large amount of ash in the box, the ash can be transferred out of the furnace body 1 and processed by pulling the ash collection box 4 out from the discharge port 12. The ash collection box 4 can only store ash, meaning that the fuel will not fall to the top of the ash collection box 4. In this case, an isolation plate for accumulating solid fuel needs to be provided on the side wall of the furnace body 1 above the ash collection box 4. The ash after fuel combustion falls into the ash collection box 4 through the holes in the isolation plate. The structure of the isolation plate and its installation method within the furnace body are existing technologies and will not be described in detail here. The ash collection box 4 can also be used to collect solid fuel and ash, meaning that the solid fuel burns directly in the ash collection box 4. In this case, the ash can only be processed after all the solid fuel has burned.
[0053] As some preferred embodiments, the side wall of the furnace body 1 is also provided with an air inlet 13 arranged in the opposite direction to the discharge port 12 along the first direction D1; and a baffle plate 5 is provided that is slidably connected to the side wall of the furnace body 1 and moves along the first direction D1 or the opposite direction of the first direction D1; when the baffle plate 5 moves to the limit position along the first direction D1, the projection of the baffle plate 5 on the side wall of the furnace body 1 where the air inlet 13 is provided covers the projection of the air inlet 13.
[0054] The air inlet 13 is located above the discharge port 12, and its main function is to connect with the outside and supply air into the furnace body 1 to aid combustion. Similar to the method of the control panel 32 blocking the fuel port 11, the baffle plate 5 controls the opening and closing of the air inlet 13 and the diameter of the air inlet by fitting against the side wall of the furnace body 1, thereby controlling the ventilation volume and facilitating the control of the combustion process.
[0055] Furthermore, the baffle plate 5 is disposed opposite to the control plate 32, and the baffle plate 5 has a second extension 51. When the baffle plate 5 moves to its limit position along the first direction D1, the second extension 51 protrudes from the furnace body 1. Similar to the first extension 321, the second extension 51 can still protrude from the upper surface of the furnace body 1 when the baffle plate 5 moves to its lowest point (limit position). The purpose is twofold: firstly, to allow the second extension 51 to cooperate with the first extension 321 to enhance the effect of blocking wind and dust; secondly, to facilitate the control of the pulling process of the baffle plate 5 when the second extension 51 is far from the heat source, and also to avoid the risk of burns. It is understood that a fireproof layer can also be provided on the surface of the extension plate 5 to achieve the effect of temperature isolation.
[0056] Furthermore, a second handle 41 is provided on the outer surface of the ash collection box 4 located on the furnace body 1; and when the baffle plate 5 moves to its limit position along the first direction D1, the second handle 41 abuts against the baffle plate 5. The second handle 41 serves both to facilitate gripping and to support the baffle plate 5, limiting the lowest point of movement of the baffle plate 5 and ensuring that the second extension 51 can always perform the function of blocking wind and dust.
[0057] Furthermore, a fixing plate 14 is provided on the side wall of the furnace body 1. The fixing plate 14 has a side limiting groove 15 that is arranged along the first direction D1 and slidably connected to the baffle plate 5. A threaded hole 16 is provided on the fixing plate 14, and a limiting bolt 17 perpendicular to the baffle plate 5 is screwed into the threaded hole 16. A resistance increasing block 18 is provided on the end of the limiting bolt 17 near the baffle plate 5.
[0058] Preferably, there are at least two fixing plates 14, symmetrically distributed on both sides of the baffle plate 5 along the third direction D3. The fixing plates 14 can be corner plates, and the inner groove of the corner plate (i.e., the side limiting groove 15) can guide the sliding trajectory of the baffle plate 5, ensuring that the baffle plate 5 can interact with the outer side wall of the furnace body 1. The height position of the baffle plate 5 can be fixed by screwing the limiting bolt 17 into the threaded hole 16 and pressing it against the baffle plate 5. The friction increasing block 18 can be made of conventional materials such as rubber, mainly used to increase the contact area with the baffle plate 5, increase the friction coefficient, and improve the fixing force of the fixing bolt 17 on the baffle plate 5.
[0059] In some preferred embodiments, an extension plate 52 is provided at the end of the wind deflector 5; the angle between the extension plate 52 and the wind deflector 5 is 60°~100°. Preferably, the extension plate 52 is perpendicular to the surface of the wind deflector 5. The first function of the extension plate 52 is to provide a handle for easy gripping; the second function is as described in the appendix. Figure 5 As shown, when the air inlet 13 is fully open, the right-angle portion formed between the extension plate 52 and the baffle plate 5 can be engaged with the upper inner wall of the oven body 1, so that the baffle plate 5 is hung on the oven body 1 in a manner parallel to the bottom surface of the oven body 1. At this time, the extension plate 5 plays the role of extending the countertop, which is convenient for placing cooking materials and other outdoor items, enriching the functions of the oven body and having the advantages of convenient conversion and strong practicality.
