Description

Technical Field

[0001] This utility model relates to the field of heating stove technology, and in particular to a household heating stove. Background Technology

[0002] Coal-fired heating stoves are heating devices that use coal as the primary fuel. They are mainly used in rural areas and peri-urban areas without centralized heating or gas supply, and are characterized by low operating costs and high thermal efficiency. They heat water by burning coal, which is then circulated through pipes to radiators to provide warmth.

[0003] Currently, existing coal-fired heating stoves mainly function for cooking and heating, which is relatively simple. In order to improve the functionality of heating stoves and meet the needs of users, the inventor designed a new type of household heating stove, which adds an oven function to the original functions, making the product more versatile. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing technologies by providing a household heating stove.

[0005] This utility model is achieved through the following technical solution: a household heating stove is provided, including a stove body, which includes a fuel compartment, a combustion chamber, a rear smoke chamber, and a chimney. The fuel compartment is connected to the combustion chamber, the upper part of the combustion chamber is connected to the upper part of the rear smoke chamber, and the rear smoke chamber is connected to the chimney. A partition is provided in the stove body to separate the combustion chamber and the rear smoke chamber. A through hole is provided on the partition, and a sealing plate that can block the through hole is slidably installed on the partition. An opening is provided on the side wall of the rear smoke chamber, and a baking tray is inserted into the rear smoke chamber through the opening and heated by the hot smoke in the rear smoke chamber.

[0015] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0016] like Figure 1-4As shown, this utility model includes a furnace body 16, which includes a fuel bin 1, a combustion chamber 2, a rear smoke chamber 3, and a chimney 4. The fuel bin 1 is connected to the combustion chamber 2, the upper part of the combustion chamber 2 is connected to the upper part of the rear smoke chamber 3, and the rear smoke chamber 3 is connected to the chimney 4. A partition 5 is provided inside the furnace body 16 to separate the combustion chamber 2 and the rear smoke chamber 3. A through hole 6 is provided on the partition 5, and a sealing plate 17 that can block the through hole 6 is slidably installed on the partition 5. An opening 7 is provided on the side wall of the rear smoke chamber 3, and the baking tray 22 is inserted into the rear smoke chamber 3 through the opening 7 and heated by the hot smoke in the rear smoke chamber 3.

[0017] In this embodiment, a fuel filling port 11 is provided on the top surface of the fuel tank 1, and a first furnace cover covers the fuel filling port 11. An observation port 12 is provided on the side of the fuel tank 1, and a second furnace cover that can be opened and closed is installed at the observation port 12. The observation port 12 can be used to add fuel on the one hand, and to open the second furnace cover on the other hand to observe the combustion situation in the combustion chamber 2.

[0018] In this embodiment, to facilitate the entry of fuel from the fuel tank 1 into the combustion chamber 2, an inclined guide plate 13 is provided at the bottom of the fuel tank 1, located directly below the fuel filling port 11. When fuel is added to the fuel filling port 11, the fuel falls onto the guide plate 13 and rolls into the combustion chamber 2 with the help of the slope of the guide plate 13.

[0019] In this embodiment, a grate 14 is provided at the bottom of the combustion chamber 2, and an ash chamber is provided below the grate 14. The ash chamber is equipped with a push-pull ash drawer 15.

[0020] In this embodiment, a cooking port 10 is provided on the top surface of the combustion chamber 2, and an installation plate 8 is provided below the cooking port 10. The installation plate 8 is fixed to the inner wall of the furnace body 16. A fire passage hole for flame to pass through is provided on the installation plate 8. A vaporizer 9 for supplementing air to the combustion chamber 2 is fixedly installed below the installation plate 8. The vaporizer 9 adopts an existing structure, and the structure of the vaporizer 9 is described in detail in patent application number 2016201584669.

[0021] In this embodiment, an upper slide rail 19 and a lower slide rail 18 are fixedly installed on the partition plate 5. The upper slide rail 19 and the lower slide rail 18 are located on the upper and lower sides of the through hole 6, respectively. A slider 20 that slides with the upper slide rail 19 and the lower slide rail 18 is fixedly connected to the sealing plate 17. A pull rod 21 is fixedly connected to the sealing plate 17. The pull rod 21 passes through the furnace wall and extends to the outside of the furnace body 16.

[0022] In this embodiment, a cover plate 23 is installed on the baking tray 22 to cover the opening 7.

[0023] In practical use, when the lever 21 is pulled out to extend the sealing plate 17, the sealing plate 17 leaves the through hole 6. Under the suction force of the chimney 4, the flue gas and flames in the combustion chamber 2 pass through the through hole 6 and enter the rear smoke chamber 3 to cook the food in the baking tray 22. When the baking tray 22 is no longer needed, the sealing plate 17 is pushed back, blocking the through hole 6. At this time, the flue gas and flames in the combustion chamber 2 rise. Part of the rising flue gas and flames are used to heat the cookware on the stove opening 10, and part of the flue gas and flames enter the upper part of the rear smoke chamber 3 from the upper part of the combustion chamber 2, and then enter the chimney 4 from the rear smoke chamber 3.

[0024] This utility model utilizes a sliding sealing plate 17 to enable flexible switching of functions, meeting various needs such as heating, cooking, and baking, thus making the heating stove more versatile.
