Description

Technical Field

[0001] This application relates to the field of cooking tools technology, specifically to a steam stove. Background Technology

[0002] In many remote mountainous and grassland areas with limited energy resources, access to energy sources such as natural gas and electricity is often restricted, posing challenges to local residents' winter heating and daily cooking. Therefore, residents typically use traditional energy sources such as coal, wood, and cow dung, but lack simple and clean indoor heating systems. Although biomass pellet fuel, such as fuel made from crop residues, is an environmentally friendly and sustainable alternative energy source, its adoption and use in these areas are not widespread, mainly due to the lack of efficient heating equipment adapted to this fuel. Existing heating equipment is often designed for a single fuel type and cannot flexibly adapt to multiple fuel sources, which limits the application of biomass pellet fuel in these energy-scarce areas.

[0026] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0027] A steam stove, as shown Figure 1 and Figure 2 It includes a stove body 1, an inner stove ring 2, a water tank 18, and a feeding device 3. The inner stove ring 2 is installed above the stove body 1. The stove body 1 is provided with a combustion chamber 4, which is located directly below the inner stove ring 2 and extends upward into the inner stove ring 2.

[0028] An outer burner ring 5 surrounds the inner burner ring 2, forming a sandwich between them. A water tank 18 is seamlessly welded to the outer burner ring 5, and small holes are provided at corresponding positions on the outer burner ring 5 to ensure communication between the sandwich and the water tank 18, allowing water from the water tank 18 to flow into the sandwich. A top cover is provided on the top of the water tank 18 for adding water.

[0029] A water passage hole 7 is provided at the bottom of the side wall of the inner stove ring 2 to allow communication between the interlayer and the interior of the inner stove ring 2. To prevent water from entering the combustion chamber 4 from the interlayer, a baffle (not shown in the figure) is installed in the inner stove ring 2. The baffle is slightly higher than the water passage hole 7 and lower than the top of the combustion chamber 4.

[0030] Multiple support legs 6 are installed at the bottom of the inner stove ring 2 and the outer stove ring 5. The support legs 6 are mounted on the outer perimeter of the stove body 1 to support the upper structure. To improve stability, the multiple support legs 6 are evenly spaced and fixed on the inner stove ring 2 along the circumference. At least one of the support legs 6 has its upper end passing through the bottom wall of the outer stove ring 5 and connecting to the top wall of the outer stove ring 5.

[0031] A chimney 8 is connected to the inner stove ring 2. The chimney 8 is installed on the side wall of the inner stove ring 2 near the top. One end extends into the inner stove ring 2, and the other end passes through the outer stove ring 5 and the water tank 18 and extends to the outside. The outer end of the chimney 8 bends downward, and a water bucket is hung at the outlet to absorb dust and other substances.

[0032] Combustion chamber 4 generates heat through combustion, and chimney 8 transfers the residual heat from inner stove ring 2 to water tank 18 to heat the water inside. At least two steam pipes are installed on the side wall of water tank 18 near the top, which can guide the steam generated after heating the water to other equipment for various cooking tasks.

[0033] Furthermore, a pressure relief valve can be installed on the water tank 18 to prevent excessive pressure inside the water tank 18.

[0034] To facilitate water drainage, a downward-facing drain pipe 9 is connected to the bottom of the inner stove ring 2, reducing the workload required for draining water.

[0035] The feeding device 3 is located on one side of the stove body 1 and the outer stove ring 5, and the other part extends into the stove body 1 to deliver fuel into the combustion chamber 4.

[0036] The feeding device 3 includes a feed hopper 10, a first feed cylinder 11, a first auger 12, a second feed cylinder 13, and a second auger 14. The feed hopper 10 is located on one side of the outer stove ring 5 and is used to hold biomass pellet fuel. The first feed cylinder 11 is located on one side of the stove body 1, below the feed hopper 10, and connected to the outlet of the feed hopper 10. The outlet of the first feed cylinder 11 is directly above the second feed cylinder 13, allowing the pellet fuel transported from the first feed cylinder 11 to be received by the second feed cylinder 13. The outlet end of the second feed cylinder 13 extends into the stove body 1 and connects to the combustion chamber 4, used to directly transport the pellet fuel into the combustion chamber 4. The first auger 12 is installed inside the first feed cylinder 11, and the second auger 14 is installed inside the second feed cylinder 13, with the second auger 14 rotating at a higher speed than the first auger 12, thus solving the problems of pellet accumulation and backfire.

[0037] A first gear 15 is coaxially fixedly connected to the first auger 12, and a second gear 16 is coaxially fixedly connected to the second auger 14. The first gear 15 and the second gear 16 are wound with the same chain. The feeding device 3 also includes a motor for driving the first gear 15 to rotate, and the radius of the first gear 15 is larger than the radius of the second gear 16.

[0038] To facilitate the addition of solid fuels such as firewood and coal, an additional fuel feeding channel can be added to the stove body 1. Large pieces of solid fuel can be added through this channel. Thus, when using this application, users can choose either solid fuel or biomass pellet fuel.

[0039] The stove body 1 is also equipped with an air duct and a fan 17. The air duct is located below the combustion chamber 4 and is used to blow air into the combustion chamber 4 under the drive of the fan 17 to ensure the normal operation of combustion.

[0040] In this embodiment, the stove body 1 and the inner stove ring 2 are connected by seamless welding technology to ensure their overall stability.

[0041] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
