Description

Technical Field

[0001] This utility model belongs to the field of fireplace technology, specifically relating to a cast iron fireplace with heat dissipation function. Background Technology

[0002] Fireplaces were originally conceived as a heating tool, serving both practical and decorative purposes. Traditional fireplaces use firewood as fuel; in recent years, cleaner and more environmentally friendly fireplaces using alcohol as fuel have gradually gained popularity. Whether wood-burning or alcohol-fueled, while decorative, their primary function remains heating. However, with the continuous improvement of people's living standards and tastes in recent years, the demand for purely decorative fireplaces that do not require heating functions has been gradually increasing in the domestic home decoration market.

[0003] In existing cast iron fireplaces, the heating element is usually installed inside the fireplace body, and heat transfer is typically achieved through thermal radiation. More advanced fireplaces may incorporate a blower to accelerate heat dissipation. However, the heating element in existing fireplaces still suffers from poor heat dissipation. Although a blower can accelerate heat flow, the internal structure is not conducive to rapid heat transfer and dissipation. Utility Model Content

[0007] As a further improvement to the above technical solution, the heating air passage includes vertical air passages located on the left and right sides of the furnace and a horizontal air passage connecting the upper ends of the two vertical air passages. The air inlet is located at the bottom of the left and right sides of the furnace body, and the air outlet is located on the front side of the furnace body.

[0008] As a further improvement to the above technical solution, the vertical airway includes a lower airway and an upper airway, wherein the width of the lower airway is smaller than the width of the upper airway.

[0009] As a further improvement to the above technical solution, several heat-conducting pipes are arranged horizontally, and the two ends of several heat-conducting pipes pass through the upper air passages of the two vertical air passages respectively.

[0010] As a further improvement to the above technical solution, the air intake channel includes two vertical channels and a horizontal channel connected to the lower end of the two vertical channels. The two vertical channels are respectively located between the lower air passage and the furnace. The left and right walls of the furnace are respectively provided with air outlets that are connected to the upper end of the two vertical channels. The air inlet is connected to the horizontal channel.

[0011] As a further improvement to the above technical solution, the furnace body is provided with an ash box located on the lower side of the furnace chamber, and a furnace door is rotatably installed on the furnace chamber.

[0012] As a further improvement to the above technical solution, the upper end of the furnace body is provided with an exhaust pipe that communicates with the upper end of the furnace chamber.

[0013] Compared with existing technologies, the advantages of this new cast iron fireplace with heat dissipation function are:

[0014] This utility model of a cast iron fireplace with heat dissipation function involves the burning of wood within the furnace. External air enters the air intake channel through an air inlet connected to the intake channel, and then enters the furnace through an air outlet, ensuring complete combustion of the wood. The heat generated by the burning wood heats the air in the heating duct, causing the hot air to rise and exit from the top of the furnace body and the air outlet of the heating duct. During this process, a blower pumps external air into the heat-conducting pipes, where the burning wood flames heat the pipes and the air within them. An exhaust fan then expels the heated air. Compared to existing technologies, this utility model of a cast iron fireplace with heat dissipation function, through the inclusion of heat-conducting pipes, a blower, and an exhaust fan, allows for more efficient use of the heat generated during combustion, enhancing the fireplace's heat dissipation capacity and providing significant warmth to the room during winter use.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0021] An embodiment of the cast iron fireplace with heat dissipation function of this utility model is as follows: Figure 1-4 As shown, the furnace includes a furnace body 1, a furnace chamber 2 inside the furnace body 1, heating air passages arranged around the furnace chamber 2 inside the furnace body 1, an air inlet 8 communicating with the heating air passages at the bottom of the furnace body 1, an air outlet 9 communicating with the heating air passages at the top of the furnace body 1, an air inlet channel for air to enter the furnace body 1 on the furnace body 1, an air inlet hole 12 communicating with the air inlet channel on the furnace body 1, and several heat-conducting pipes 14 extending from one end of the furnace body 1 to the other end and passing through the furnace chamber 2 on the furnace body 1. An air inlet pipe 15 located outside one end of the heat-conducting pipe 14 and an air outlet pipe 16 located outside the other end of the heat-conducting pipe 14 are provided on the furnace body 1. An air intake fan 18 is connected to the air inlet pipe 15 through a first bracket 17, and an exhaust fan 20 is connected to the air outlet pipe 16 through a second bracket 19.

[0022] The heating gas duct includes vertical gas ducts 6 located on the left and right sides of the furnace chamber 2 and horizontal gas ducts 7 connecting the upper ends of the two vertical gas ducts 6. The air inlet 8 is located at the bottom of the left and right sides of the furnace body 1, and the air outlet 9 is located on the front side of the furnace body 1. The vertical gas duct 6 includes a lower gas duct 61 and an upper gas duct 62, and the width of the lower gas duct 61 is smaller than the width of the upper gas duct 62.

[0023] Several heat-conducting pipes 14 are arranged horizontally, with both ends of each pipe passing through the upper air passages 62 of two vertical air passages 6. The air inlet channel includes two vertical passages 10 and a horizontal passage 11 connecting the lower ends of the two vertical passages 10. The two vertical passages 10 are located between the lower air passage 61 and the furnace 2, respectively. The left and right walls of the furnace 2 are respectively provided with air outlets 13 communicating with the upper ends of the two vertical passages 10, and the air inlet 12 is connected to the horizontal passage 11. The furnace body 1 is provided with an ash box 5 located on the lower side of the furnace 2, and a furnace door 4 is rotatably installed on the furnace 2. The upper end of the furnace body 1 is provided with an exhaust pipe 3 communicating with the upper end of the furnace 2.

[0024] When this cast iron fireplace with heat dissipation function is in use, wood burns inside the furnace chamber 2. External air enters the air intake channel through the air inlet 12, which connects to the air intake channel, and then enters the furnace chamber 2 through the air outlet 13, ensuring complete combustion of the wood. The heat generated by the burning wood heats the air in the heating duct, causing the hot air to rise and exit from the top of the furnace body 1 and the air outlet 9 of the heating duct. During this process, the blower 18 pumps external air into the heat-conducting pipe 14, and the flames from the burning wood heat the heat-conducting pipe 14 and the air within it. The exhaust fan 20 then exhausts the heated air. Compared to existing technologies, this cast iron fireplace with heat dissipation function, by incorporating the heat-conducting pipe 14, the blower 18, and the exhaust fan 20, allows for more efficient use of the heat generated by combustion, enhancing the fireplace's heat dissipation capacity and providing considerable warmth to the room during winter use.
