[0019] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0020] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0021] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] In this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or an interaction between two components. However, the phrase "direct connection" indicates that the two connected entities are not connected through an intermediate structure, but are connected to form a whole through a connecting structure. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0023] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0024] In this utility model, if Figure 1-3 As shown, a heating stove is provided, comprising an outer cylinder 1 and an inner cylinder 2 arranged on the inner side of the outer cylinder 1, a water containing chamber 3 is formed between the outer cylinder 1 and the inner cylinder 2, and a smoke chamber 4 is formed on the inner side of the inner cylinder 2; the outer cylinder 1 is provided with two circulation pipes 5 at vertical intervals, and the outer cylinder 1 is also provided with a water supply pipe 6; the inner cylinder 2 is provided with at least two connecting pipes 7 at vertical intervals in the smoke chamber 4, both ends of the connecting pipes 7 are respectively connected to the water containing chamber 3, and the vertical projections of two adjacent connecting pipes 7 are staggered.

[0025] When the heating stove of this invention is in use, the inner cylinder 2 can be connected to the chimney of the stove, allowing hot flue gas to flow through the inner cylinder 2. The inner cylinder 2 and the connecting pipe 7 heat the water in the inner water chamber 3. The water in the water chamber 3 can then flow into the connected radiator group through one of the circulation pipes 5. The water in the radiator group, after heat exchange, then flows back into the water chamber 3 through the other circulation pipe 5, completing a heat exchange cycle. The water supply pipe passes through an external water supply tank to replenish the water consumed in the water chamber and the radiator group.

[0026] The present invention can directly recover the heat from the flue gas and can be installed directly on the chimney during installation, making it easy to install. Compared to the prior art method of integrally connecting the furnace body to the water jacket, the present invention is more flexible in installation and use. In addition, the present invention uses the inner tube 2 and the outer tube 1 to enclose the water chamber 3, and the smoke chamber 4 is formed inside the inner tube 2, which can make the entire heating stove have an elongated shape. By controlling the cross-sectional area of ​​the water chamber 3, the heat exchange area of ​​the inner tube 2 corresponding to the unit water volume in the water chamber 3 can be increased, thereby improving the heating efficiency of the water in the water chamber 3 and achieving a rapid temperature increase.

[0027] Moreover, the present invention provides a connecting pipe 7 inside, which can be used to heat water. At the same time, when the circulation pipe 5 circulates water, the connecting pipe 7 is used to promote the flow of water in the water chamber 3 to fully utilize the heated water in the water chamber 3.

[0028] By arranging adjacent communicating tubes 7 in a staggered manner, the communicating tubes 7 can be utilized to further guide the flue gas to mix and flow, thereby promoting the flue gas heat release efficiency.

[0029] In a preferred embodiment, a further optimized configuration of the present invention is that an outwardly protruding limiting plate 8 is provided at the end of the outer cylinder 1 , and the inner cylinder 2 extends outward of the limiting plate 8 .

[0030] As shown in the figure, by extending the inner tube 2 out of the outer side of the limiting plate 8, when the inner tube 2 is connected to the chimney, it is convenient to insert the inner tube 2 into the inner side of the chimney and then use the limiting plate 8 to limit the chimney.

[0031] By arranging the limiting plate 8 to protrude outward from the outer side of the outer cylinder 1 , when the limiting plate 8 is connected to the outer cylinder 1 , the outer cylinder 1 can be directly welded to the inner side of the limiting plate 8 , so as to facilitate the welding connection.

[0032] In a selected embodiment, a further optimization of the present invention is that the distance between the outer surface of the inner cylinder 2 and the inner surface of the outer cylinder 1 is greater than or equal to 1 cm and less than or equal to 5 cm. By controlling the distance between the outer surface of the inner cylinder 2 and the inner surface of the outer cylinder 1, sufficient water can be ensured in the water chamber 3 for heating, while preventing the problem of slow heating caused by excessive water in the water chamber 3.

[0033] exist Figure 1 In the embodiment shown, the inner tube 2 is configured as a single straight tube, but this is not a limitation of the present invention. In an optional embodiment, the inner tube 2 may be configured in a multi-section curved form to extend the flue gas heat exchange pipeline within a specific space. Figure 2 As shown, the inner tube 2 includes multiple sections, with at least two adjacent sections being bent adjacent to each other. As shown in the figure, this can increase the heat exchange distance between the flue gas and water at the location where the chimney is arranged in the heating room, thereby improving the utilization of the flue gas heat.

[0034] As a preferred further optimization of the present invention, one end of the inner tube 2 forms an air inlet, and the other end forms an air outlet 9. The heating stove also includes an exhaust fan 10, which can be installed at the air outlet 9 of the inner tube 2. This facilitates the flow of smoke, thereby reducing the impact of the connecting pipe 7 on the flow of smoke. The exhaust fan 10 can be installed at the air outlet 9 of the inner tube 2 or on a chimney connected to the inner tube 2 at the air outlet 9.

[0035] In a selected embodiment, a further optimized setting of the utility model is that at least one of the connecting pipes 7 forms a straight connecting pipe 11 arranged at the position of the circulation pipe 5, and the vertical distance between the straight connecting pipe 11 and the circulation pipe 5 at the corresponding position is less than or equal to 5 cm.

[0036] By setting up the straight connecting pipe 11, when the water at the corresponding position of the circulation pipe 5 flows, the flow rate of the water flow can be used to drive the water in the straight circulation pipe 5 to flow quickly, so as to promote the circumferential flow of the water in the water holding chamber 3, so that the water in the water holding chamber 3 is evenly heated and circulated.

[0037] In a preferred embodiment, a further optimization of the present invention is that the angle between the axis of the straight connecting pipe 11 and the axis of the corresponding circulation pipe 5 is less than or equal to 30°. As shown in the figure, by controlling the angle between the axis of the straight connecting pipe 11 and the axis of the corresponding circulation pipe 5, the water flow in the circulation pipe 5 can be used to drive the water flow in the straight connecting pipe 11.

[0038] In a preferred embodiment, the present invention is further optimized in that: Figure 3 As shown, at least two smoke baffles 12 are spaced apart along the inner axis of the inner cylinder 2, with adjacent smoke baffles 12 arranged in a staggered arrangement along the projection of the axis of the inner cylinder 2. As shown in the figure, the smoke baffles 12 promote uniform heat release and flow of smoke within the inner cylinder 2, and also increase the length of the smoke flow path within the inner cylinder 2, thereby improving the efficiency of heat release.

[0039] The various embodiments in this specification are described in a progressive manner. Similar parts between the various embodiments can be referred to in conjunction with each other. Each embodiment focuses on the differences between the other embodiments. In particular, the system embodiments are generally similar to the method embodiments, so the description is relatively simple. For relevant parts, refer to the description of the method embodiments.

[0040] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
