Description

Technical Field

[0001] The utility model relates to the field of stove equipment, in particular to an energy-saving smoke pipe and a stove thereof. Background Art

[0002] As heating equipment, stoves have broad market prospects. Biomass fuel stoves are more environmentally friendly than coal stoves, have a higher heat output than electric stoves, and are renewable and easy to store, making them popular among users.

[0003] Existing combustion furnaces need to be equipped with smoke pipes to exhaust smoke, and the smoke contains a large amount of waste heat, resulting in a large amount of heat waste.

[0004] Chinese patent CN201621003409.X discloses a stove with a flue gas waste heat utilization port, wherein a stove platform is provided at the upper end of the stove body, a first partition is provided in the stove body, a through hole is provided on the first partition corresponding to the stove core, a first fire-blocking ring is provided on the first partition, a first opening is provided on the stove platform corresponding to the first fire-blocking ring, a second opening is also provided on the stove platform, a second fire-blocking ring is provided on the first partition corresponding to the second opening, the internal space of the second fire-blocking ring is connected to the internal space of the first fire-blocking ring by providing a first connecting pipe, and the smoke exhaust pipe is connected to the internal space of the second fire-blocking ring.

[0005] The stove has a flue gas waste heat utilization structure installed inside the stove, but the stove body is huge and inconvenient to install and use. Moreover, when the stove heats up, the utilization rate of the flue gas waste heat will be greatly reduced. Utility Model Content

[0006] The purpose of the present invention is to overcome the above-mentioned background technical difficulties and provide an energy-saving smoke pipe and stove thereof that can utilize the waste heat of smoke.

[0007] To achieve the above-mentioned purpose, the technical solution adopted is: an energy-saving smoke pipe, comprising a smoke-wrapped pipe connected to a furnace body, the smoke-wrapped pipe being connected to a ground pipe, the ground pipe being away from the furnace body and the smoke-wrapped pipe along the floor, the ground pipe being further connected to a heat sink and an exhaust fan through the smoke pipe; the smoke-wrapped pipe being arranged as a flat structure, the ground pipe being a flat tube; the surface of the heat sink being provided with heat dissipation fins, and a circuitous flue being provided inside the heat sink.

[0008] Furthermore, the smoke bag tube is arranged through the foot box of the furnace body.

[0009] Furthermore, the exhaust fan is a centrifugal fan, which is arranged at the smoke outlet; the blades of the exhaust fan are arranged on one side of the smoke pipe, and the motor of the exhaust fan is arranged on the side away from the smoke pipe.

[0010] Furthermore, the cigarette bag tube is provided with a vertical pipe connected to the ground pipe.

[0011] Furthermore, the heat sink comprises a bottom plate and a cover plate, a partition forming a circuitous flue is provided between the bottom plate and the cover plate, and a sealing layer is also provided between the bottom plate and the cover plate.

[0012] And a stove with the energy-saving smoke pipe.

[0013] The beneficial effects of adopting this solution are: this energy-saving smoke pipe and its associated stove utilize waste heat from flue gases through a smoke pipe structure outside the furnace body, without increasing the furnace body's volume. Instead, the smoke pipe portion at the existing furnace body connection can be concealed, making the furnace more refined and increasing the effective seating area. Furthermore, the utilization rate of waste heat from flue gases does not decrease as the furnace body temperature rises. The results are excellent and worthy of widespread adoption.

[0019] The following is a clear and complete description of the technical solution of the present invention in conjunction with the specific embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of the present invention. Example 1

[0020] like Figure 1 An energy-saving smoke pipe includes a smoke pipe 3 connected to a stove body 1. This pipe is connected to a floor pipe 4, which extends away from the stove body 1 and the pipe 3 along the floor. The floor pipe 4 is also connected to a heat sink 5 and an exhaust fan 6 through the smoke pipe. The smoke pipe 3 connects the stove body 1 and the smoke pipe. In existing stoves, the smoke pipe 3 typically extends from the stove body along the underside of the tabletop to the edge of the tabletop. This reduces the effective seating area for heating, making it difficult for people sitting near the pipe to pick up food when dining in the stove.

[0021] In this embodiment, the smoke pipe 3 is a flat structure, positioned snugly against the stove body 1. It extends downward through the foot box 2 of the stove body 1 and then connects to the floor pipe 4. Conventional stoves have smoke pipes that extend vertically upward from the edge of the tabletop, then pass through a high point in the room to connect to the smoke outlet. This makes the smoke pipe unsightly and disrupts movement indoors. The flattened floor pipe 4 minimizes the impact on both aesthetics and movement.

[0022] The surface of the heat sink 5 is provided with heat dissipation fins, and a circuitous flue is provided inside the heat sink 5 to increase the waste heat absorption and heat dissipation effect, and use the waste heat of the flue gas for indoor heating, which significantly improves the heating effect of the stove.

[0023] The exhaust fan 6 is a centrifugal fan installed at the smoke outlet. Its blades are located on one side of the smoke duct, and its motor is located away from the duct. This prevents smoke from contaminating the motor, extending its lifespan. Furthermore, the location of the exhaust fan 6 outside the smoke outlet reduces noise impact on the room.

[0024] The heat sink 5 comprises a base plate and a cover plate, a partition forming a circuitous flue is provided between the base plate and the cover plate, and a sealing layer is provided between the base plate and the cover plate. The base plate and the cover plate can be made of iron or aluminum and are locked by screws. Example 2

[0025] like Figure 2 On the basis of the above embodiment 1, the smoke package tube 3 of the existing stove can be improved, and a vertical pipe 30 is provided under the smoke package tube 3 to connect to the ground pipe 4. The energy-saving smoke tube of this application can be directly used in the existing stove. Example 3

[0026] like Figure 3 On the basis of the above embodiment 1, the smoke package tube 3 can be arranged inside the furnace body, and then pass through the foot box and connect to the ground pipe 4. The smoke package tube structure connected to the furnace body can be designed to be hidden, which can improve the aesthetics of the furnace body and increase the effective seating area. Example 4

[0027] This application also includes all stoves having the energy-saving smoke pipe structure of the above embodiments.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.

[0029] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
