[0032] To make the purpose, technical solutions and advantages of the present invention clearer, the following will describe the technical solutions of the present invention in detail. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present invention.
[0033] As described in the background art, in the prior art, the inner liner of the wood stove is cylindrical. Firewood, branches, leaves, etc. are generally fed into the inner liner from the side of the inner liner. The ratio of the height to the diameter of the inner liner is about 0.8 - 1.2 (the height is about 20 cm and the diameter is about 25 cm). Therefore, this kind of inner liner cannot accommodate firewood and branches with longer lengths.
[0034] Based on this, the present utility model provides a heating wood stove. The inner liner of the present utility model is of a cylindrical structure and is horizontally placed. The ratio of its height to the diameter is greater than 1.5. In this way, the horizontally placed inner liner is relatively longer, facilitating the accommodation of firewood and branches with longer lengths, eliminating the need to break the branches and firewood, and also avoiding repeated addition of firewood, reducing the workload.
[0035] The following will specifically describe a preferred embodiment of the heating wood stove of the present utility model in conjunction with the attached Figures 1 - 3 figures.
[0036] As Figure 1 shown and Figure 2 described, the structure diagram of the heating wood stove of the present utility model is shown. This kind of heating wood stove includes an outer furnace barrel 1, a base 2, and an inner liner 3. The base 2 is hollow and is located below the outer furnace barrel 1. The inner liner 3 is located in the inner cavity of the outer furnace barrel 1 and is slightly smaller than the outer furnace barrel 1. There is a gap between the inner liner 3 and the outer furnace barrel 1, and this gap forms an air duct 12.
[0037] The inner liner 3 of this embodiment is cylindrical, similar to the shape of a gas cylinder. The ratio of its height to the diameter is greater than 1.5. Due to the higher height, when placed horizontally, it is relatively long and can accommodate firewood with longer lengths.
[0038] In order to provide the air required for the combustion of firewood, as Figure 2 shown, a first air inlet 11 is provided on the outer furnace barrel 1 of this embodiment. A furnace grate 33 and a smoke outlet 32 are provided on the inner liner 3. The furnace grate 33 and the smoke outlet 32 are arranged oppositely. The furnace grate 33 is located below the inner liner 3, and the smoke outlet 32 is located above the inner liner 3. The smoke outlet 32 can be located above the side of the furnace grate 33 or directly above the furnace grate 33. The present utility model does not limit this. The first air inlet 11 and the furnace grate 33 are connected through the air duct 12. Here, the air duct 12 refers to the gap between the inner liner 3 and the outer furnace barrel 1.
[0039] A second air inlet 31 is provided below the furnace grate 33. The second air inlet 31 and the furnace grate 33 can be conducted. The first air inlet 11 and the second air inlet 33 are connected through the air duct 12.
[0040] It should be noted that the furnace grate 33 of this embodiment is in a grid shape and is evenly distributed at the bottom of the inner liner 3. In addition to serving as an ash outlet, the furnace grate 33 can also serve as an air inlet.
[0041] In addition, it also includes a firewood delivery pipe 4. The firewood delivery pipe 4 is arranged on one side of the outer barrel 1 of the furnace body and extends towards the inside of the outer barrel 1 of the furnace body to be connected and communicated with the inner liner 3. The end of the firewood delivery pipe 4 is provided with a firewood door, and the firewood door is a visible door. Through the visible door, the combustion condition of the inner liner 3 can be observed.
[0042] For example, in this embodiment, the diameter of the inner liner 3 is 50 cm, and the length of the firewood delivery channel is 18 cm. Therefore, the length of the fuel of the heating firewood stove can reach 68 cm, that is, firewood with a length of 68 cm can be placed. The height of the inner liner 3 is 32 cm, and multiple firewoods of different sizes can be placed at the same time. That is to say, during the use process by the user, the fuel required by the stove can be much longer than the length of the firewood.
[0043] However, for the conventional stoves on the market, the diameter of the inner liner 3 is only 24 cm and the height is about 20 cm. For such stoves with a small inner liner 3, the fuel can only be placed very short and in small amounts. Because, the larger the inner liner 3 of the stove, the more fuel can be put in, and thus the better the heating effect. In addition, adding fuel at one time can extend the heating time and avoid intensive fuel addition during the use process. For the ordinary stoves in the prior art, the heating effect can only be obvious in an indoor space of 10 - 25 square meters, while the heating area of the stove in this embodiment can achieve an ideal effect in an indoor area of 10 - 50 square meters.
[0044] It should be noted that it also includes a seat ring 34. The seat ring 34 is located between the inner liner 3 and the base 2. The seat ring 34 in this embodiment is annular, that is, a second air inlet 31 is formed.
[0045] In order to control the air intake of the inner liner 3, as Figure 2 shown, a second air inlet control member 5 is arranged in the base 2 of this embodiment. The second air inlet control member 5 is arranged below the furnace grate 33 and is closely adjacent to the second air inlet 31, and is used to control the air intake of the second air inlet 31.
[0046] Specifically, the second air inlet control member 5 includes a shielding plate 51 and a pull rod 52. One end of the pull rod 52 is fixedly connected to the shielding plate 51, and the other end of the pull rod 52 extends outwards to the outside of the outer barrel 1 of the furnace body.
[0047] When holding the end of the pull rod 52 and pulling it outwards, the shielding plate 51 moves away from the second air inlet 31, and the second air inlet 31 is opened. Air can enter the inner liner 3 through the second air inlet 31 and the furnace grate 33. When holding the end of the pull rod 52 and pushing the shielding plate 51 inwards, the shielding plate 51 moves towards the second air inlet 31, and the second air inlet 31 is closed, and air cannot enter the inner liner 3 through the second air inlet 31.
[0048] In addition, an ash receiving box 21 is also provided inside the base 2. The ash receiving box 21 is arranged below the second air inlet 31, that is, below the toilet seat 34. The ash receiving box 21 is used for receiving ash.
[0049] An oven 6 is provided on one side of the outer barrel 1 of the furnace body. The oven 6 is arranged adjacent to the air duct 12. The heat generated by the combustion of the inner tank 3 is dissipated outward through the air duct 12, and the heat heats the oven 6 during the transportation process.
[0050] As a preferred embodiment, as Figure 2 and Figure 3 shown, a gasification chamber 7 is provided at the middle position above the outer barrel 1 of the furnace body. A smoke burner 8 is provided inside the gasification chamber 7. Both the gasification chamber 7 and the smoke burner 8 are annular. A gasification channel 72 is formed between the gasification chamber 7 and the smoke burner 8. The gasification channel 72 is communicated with the air duct 12. Exhaust holes 82 are provided on the inner wall of the smoke burner 8. The gasification channel 72 is communicated with the exhaust holes 82.
[0051] Specifically, a plurality of third air inlets 71 are provided on the outer wall of the gasification chamber 7. The third air inlets 71 are simultaneously communicated with the air duct 12 and the gasification channel 72. Four fourth air inlets 83 are provided on the outer wall of the smoke burner 8. The fourth air inlets 83 are communicated with the gasification channel 72.
[0052] The gasification channel 72 is communicated with the smoke burner 8. Air enters the gasification chamber 7 from the air duct 12, forms a cyclone in the gasification channel 72 of the gasification chamber 7, enters the smoke burner 8 through the fourth air inlets 83, forms a cyclone shape again in the smoke burner 8, and performs secondary combustion on the smoke inside the inner tank 7 through the exhaust holes 82. Then, the generated waste gas is discharged to the outside through the smoke pipe 9 connected to the smoke exhaust port.
[0053] The specific process is as follows: Wind enters the air duct 12 from the first air inlet 11. While the wind moves, it takes away the heat diffused from the inner tank 3 to the air duct 12, and then enters the gasification chamber 7 through the third air inlets 71 on the side wall of the gasification chamber 7. Since the gasification chamber 7 is of an annular structure, the wind carrying heat swirls in the gasification chamber 7. During the swirling process, it enters the smoke burner 8 through the fourth air inlets 83 on the outer wall of the smoke burner 8. At this time, there is unburned firewood coming out of the inner tank 3 in the smoke burner 8. Then, it diffuses through the exhaust holes 82 on the inner wall of the smoke burner 8 to perform secondary combustion on the smoke generated by the inner tank 2. With the assistance of the combustion-supporting wind at the exhaust holes 82, the smoke is further burned, so that the smoke reaches the purpose of full combustion, thereby achieving the effect of energy conservation and environmental protection.
[0054] That is, when the second air inlet 31 of this embodiment is closed, it is in the gasification mode, and when it is opened, it is in the direct combustion mode.
[0055] As a preferred embodiment, as Figure 3As shown in the figure, there are prism-shaped teeth 81 above the smoke burner 8. The prism-shaped teeth 81 are arranged in a ring at a preset distance interval. After the smoke burner 8 burns sufficiently, further heat is generated. The heat is discharged outward through the gaps between adjacent prism-shaped teeth 81, so that the generated heat can be evenly discharged outward.
[0056] And for exhausting smoke outward, in this embodiment, the gasification chamber 7 is communicated with the flue 9, that is, the smoke generated by the inner liner 3 and the smoke burner 8 is discharged outward through the flue 9.
