Description

Technical Field

[0001] This utility model relates to the technical field of fireplace heating devices, specifically to a wind-heated pellet fireplace heating device. Background Technology

[0002] In the field of winter heating, pellet fireplaces, as a type of heating equipment that uses wood pellets as fuel, are widely used in home and small venue heating due to their environmentally friendly and efficient characteristics.

[0003] Currently, most pellet fireplaces on the market use a water-based heating system to provide whole-house heating. Their working principle is as follows: heat is released by burning wood pellets, which then heat the water inside the device. Once the water is heated, a water pump delivers the hot water to pipes and radiators throughout the house, ultimately providing heating through the dissipation of heat from the hot water.

[0004] However, this type of hydronic heating has significant limitations. Because its heating process involves multiple stages, including fuel combustion to heat the water, water temperature rise, hot water delivery, and radiator heat dissipation, the heating system takes a considerable amount of time from startup to effective heating. Especially in cold winters, users often have to wait a long time after turning on the fireplace before feeling a noticeable rise in indoor temperature, indicating a significant delay in heat output. This not only affects the user's immediate heating experience but also reduces the ease of use and energy efficiency of pellet fireplaces, making it difficult to meet users' needs for rapid heating.

[0005] Therefore, existing pellet fireplaces using water heating have problems such as long heating start-up time and significant heat output delay, and there is an urgent need to improve the heating method or optimize the system structure to improve heating response speed and user experience. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of this, the present invention provides a wind-heated pellet fireplace heating device, which overcomes the defects of existing pellet fireplaces that use water heating, resulting in long heating start-up time and significant heat output delay.

[0008] (II) Technical Solution

[0009] To solve the aforementioned technical problem, this utility model provides a particle fireplace heating device, including a particle fireplace body, multiple hot air conveying pipes, and several conveying fans. The top of the particle fireplace body has multiple upper hot air outlets spaced apart, and the interior of the particle fireplace body has a hot air channel. The upper hot air outlets are connected to the air outlets of the hot air channel. The multiple hot air conveying pipes are connected one-to-one with the multiple upper hot air outlets, and the conveying fans are installed inside the outlets of the hot air conveying pipes. During heating, hot air in the hot air channel is conveyed to the hot air conveying pipes through the upper hot air outlets. The conveying fans provide power to the hot air and control its flow path to deliver it to each room, ultimately achieving whole-house heating through thermal convection.

[0010] In some embodiments, the front end of the pellet fireplace body is provided with at least one front hot air outlet, which is used to heat the room where the pellet fireplace body is located.

[0011] In some embodiments, the front hot air outlet is arranged close to the upper hot air outlet, the hot air channel is arranged at an angle, and the front hot air outlet is connected to the air outlet end of the hot air channel.

[0012] In some embodiments, a combustion chamber is provided on the front side of the interior of the pellet fireplace body. An outer pipe is arranged at an angle on one side of the combustion chamber. Multiple exhaust pipes are evenly distributed inside the outer pipe. One end of the exhaust pipe is connected to the combustion chamber. A hot air passage is formed between the outer pipe and the exhaust pipe. When the high-temperature flue gas generated in the combustion chamber enters the exhaust pipe, the high-temperature flue gas heats the air in the hot air passage into hot air through heat conduction.

[0013] In some embodiments, a smoke exhaust box and a smoke exhaust fan are installed on the rear interior side of the pellet fireplace body, and the other end of the exhaust pipe is connected to the smoke exhaust box; the high-temperature flue gas generated in the combustion chamber is discharged to the outside through the exhaust pipe, the smoke exhaust box and the smoke exhaust fan in sequence.

[0014] In some embodiments, a grate is installed in the combustion chamber, a hopper is installed on the rear side of the outer tube, and a screw conveyor is installed at the lower end of the hopper. The screw conveyor is used to transport the material to be burned in the hopper to the grate.

[0015] In some embodiments, a heating fan is installed on the rear interior side of the pellet fireplace body, and the air inlet of the hot air duct is connected to the heating fan. The heating fan is used to drive the hot air in the hot air duct to rise to the upper hot air outlet.

[0016] In some embodiments, the front end of the pellet fireplace body is hinged with a door for opening and closing the combustion chamber, and the door is equipped with a viewing window; the top of the pellet fireplace body is detachably equipped with a feeding cover for covering the hopper feeding port.

[0017] In some embodiments, valves are installed at the upper hot air outlet and / or the front hot air outlet.

[0018] In some embodiments, there are two upper hot air outlets and two hot air delivery pipes, and one front hot air outlet.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the beneficial effects that at least one technical solution adopted in the embodiments of this specification can achieve include at least:

[0021] 1) Utilizing common components such as pellet fireplace bodies, hot air delivery pipes, and delivery fans, a unique structural design forms a highly efficient air-heating system. Compared to some complex and expensive heating equipment, this significantly reduces equipment procurement costs, saving users money. Its structural design is simple and compact, with a reasonable layout of components. Compared to the numerous complex pipes and equipment involved in water-based heating systems, the installation complexity of this device is greatly reduced. At the same time, due to the relatively small number of components, troubleshooting is easier when equipment malfunctions, allowing for quick problem location and improving the convenience of later maintenance, thus reducing maintenance costs and time.

[0022] 2) The use of conveying fans to drive the hot air delivery provides a stable and continuous power source. This not only enables long-distance hot air delivery, ensuring effective heating in all rooms, but also increases the hot air velocity by approximately 45%, significantly shortening the time it takes for the hot air to reach each room. This greatly improves the heating response speed, allowing the room to heat up faster and significantly enhancing the user's immediate heating experience. The conveying fans allow for flexible control of the hot air flow path and the start / stop of the delivery, enabling precise delivery of hot air to rooms requiring heating based on actual needs. This avoids unnecessary heat waste, achieves precise heating, effectively improves energy efficiency, reduces energy consumption, and fulfills the concept of energy conservation and environmental protection while meeting user heating needs.

[0023] 3) The top of the air-heated pellet fireplace has two upper hot air outlets, which avoids too many branches in the hot air delivery pipe. According to practical experience, the energy efficiency decreases by about 15% for each additional branch in the hot air delivery pipe. This device effectively reduces the energy efficiency loss caused by too many pipe branches through this optimized layout, ensuring that the heating system can operate with high energy efficiency and provide users with efficient heating services.

[0036] Combination Figures 1-5As shown, this utility model provides a pellet fireplace heating device, including a pellet fireplace body 1, multiple hot air conveying pipes 2, and several conveying fans 3. Multiple upper hot air outlets 101 are spaced apart at the top of the pellet fireplace body 1. A hot air channel 102 is provided inside the pellet fireplace body 1, and the upper hot air outlets 101 are connected to the air outlets of the hot air channel 102. The number of hot air conveying pipes 2 is matched to the number of upper hot air outlets 101. The hot air conveying pipes 2 are laid in the room, and each hot air conveying pipe 2 has several branches. Multiple hot air conveying pipes 2 are connected one-to-one with multiple upper hot air outlets 101. The conveying fans 3 are installed inside the outlets of the hot air conveying pipes 2. The conveying fans 3 provide power for the flow of hot air within the hot air conveying pipes 2, increasing the hot air velocity and enabling long-distance transport of hot air within the hot air conveying pipes 2. By controlling the flow path and start / stop of the hot air transport by the conveying fans 3, rapid and precise heating is achieved.

[0037] During heating, the hot air in the hot air duct 102 is transported to the hot air delivery pipe 2 through the upper hot air outlet 101. The delivery fan 3 provides power to the hot air in the hot air delivery pipe 2 and controls its flow path to deliver it to each room, ultimately achieving whole-house heating through heat convection.

[0038] This air-cooled pellet fireplace heating system uses common components such as the pellet fireplace body, hot air delivery pipes, and delivery fans. Through a unique structural design, it forms a highly efficient air-cooled heating system. Compared to some complex and expensive heating equipment, it significantly reduces equipment procurement costs, saving users money. Its structural design is simple and compact, with a reasonable layout of each component. Compared to the numerous complex pipes and equipment involved in water-based heating systems, the installation complexity of this device is greatly reduced. At the same time, due to the relatively small number of components, troubleshooting is easier when equipment failure occurs, allowing for quick problem location and improving the convenience of later maintenance, thus reducing maintenance costs and time.

[0039] The system employs a conveyor fan to drive the hot air delivery, providing a stable and continuous power source. This not only enables long-distance hot air transport, ensuring effective heating in all rooms, but also increases the hot air velocity by approximately 45%, significantly shortening the time it takes for the hot air to reach each room. This dramatically improves the heating response speed, allowing the room to heat up faster and greatly enhancing the user's immediate heating experience. The conveyor fan allows for flexible control of the hot air flow path and its start / stop, precisely delivering hot air to rooms requiring heating based on actual needs. This avoids unnecessary heat waste, achieving precise heating, effectively improving energy efficiency, and reducing energy consumption. While meeting users' heating needs, it also embodies the concept of energy conservation and environmental protection.

[0040] In some embodiments, such as Figure 1, Figure 2 and Figure 4 As shown, to enhance the functionality of the pellet fireplace body 1, at least one front hot air outlet 103 is provided at the front end of the pellet fireplace body 1. The front hot air outlet 103 is used to heat the room where the pellet fireplace body 1 is located. The front hot air outlet 103 is arranged close to the upper hot air outlet 101, the hot air duct 102 is arranged at an angle, and the front hot air outlet 103 is connected to the air outlet end of the hot air duct 102.

[0041] In some embodiments, such as Figures 1 to 3 As shown, there are two upper hot air outlets 101 and two hot air delivery pipes 2, and one front hot air outlet 103. This structure, with two upper hot air outlets 101 at the top of the pellet fireplace body 1, can better meet the heating needs of multiple rooms and reduce the number of branches in the hot air delivery pipe 2. Experiments have verified that for every additional pipe branch, the heating efficiency of the pellet fireplace decreases by approximately 15%. The dual-pipe design effectively avoids heat loss due to excessive branches, ensuring heating efficiency.

[0042] In some embodiments, such as Figure 4 As shown, a combustion chamber 104 is located on the front side of the interior of the pellet fireplace body 1, which is used for burning pellets. An outer pipe 11 is arranged at an angle on one side of the combustion chamber 104. Multiple exhaust pipes 12 are evenly distributed within the outer pipe 11, with one end of each exhaust pipe 12 connected to the combustion chamber 104. A hot air passage 102 is formed between the outer pipe 11 and the exhaust pipes 12. When the high-temperature flue gas generated in the combustion chamber 104 enters the exhaust pipe 12, the high-temperature flue gas heats the air in the hot air passage 102 into hot air through heat conduction. This structure, using an angled outer pipe 11, extends the length of the hot air passage 102 and the exhaust pipes 12, making the path of the high-temperature flue gas through the exhaust pipe 12 longer and the heat conduction time longer. Consequently, the temperature of the hot air in the hot air passage 102 is higher, resulting in better heating. Furthermore, by using heat conduction to heat the air, flue gas does not enter the hot air passage 102, leading to a better user experience.

[0043] In some embodiments, such as Figure 4 and Figure 5 As shown, a smoke exhaust box 13 and a smoke exhaust fan 14 are installed on the rear side of the interior of the pellet fireplace body 1. The other end of the exhaust pipe 12 is connected to the smoke exhaust box 13. The high-temperature flue gas generated by the combustion chamber 104 is discharged to the outside through the exhaust pipe 12, the smoke exhaust box 13 and the smoke exhaust fan 14 in sequence.

[0044] In some embodiments, such as Figure 4 and Figure 5As shown, a grate 15 is installed inside the combustion chamber 104, and a hopper 16 is installed on the rear side of the outer tube 11. The hopper 16 is funnel-shaped and used to hold the material to be burned. A screw conveyor 17 is installed at the lower end of the hopper 16. The material to be burned in the hopper 16 can fall into the screw conveyor 17 under the action of gravity. The screw conveyor 17 is used to transport the material to be burned in the hopper 16 to the grate 15.

[0045] In some embodiments, such as Figure 4 and Figure 5 As shown, a heating fan 18 is installed on the rear side of the interior of the pellet fireplace body 1. The air inlet of the hot air duct 102 is connected to the heating fan 18. The heating fan 18 is used to drive the hot air in the hot air duct 102 to rise to the upper hot air outlet 101 and the front hot air outlet 103.

[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the front end of the pellet fireplace body 1 is hinged with a door 19 for opening and closing the combustion chamber 104. A viewing window is installed on the door 19, through which the combustion situation inside the combustion chamber 104 can be observed. The top of the pellet fireplace body 1 is detachably equipped with a feeding cover 10 for covering the feeding port of the hopper 16. The feeding cover 10 can be opened to add fuel into the hopper 16 through the feeding port.

[0047] In some embodiments, valves are installed at the upper hot air outlet 101 and / or the front hot air outlet 103. These valves are used to open and close the hot air outlet 101 or the front hot air outlet 103. This structure, by providing valves, allows for the opening and closing of the hot air outlet 101 or the front hot air outlet 103, thereby achieving the distribution of hot air flow among the three hot air outlets and ultimately controlling the airflow speed and temperature. The valves are existing technology and will not be described in detail in this embodiment.

[0048] The specific operation of this air-cooled pellet fireplace heating system is as follows:

[0049] Wood is fed into the hopper from the outside and stored there. When needed for combustion, the wood is metered and fed into a screw conveyor, which then transports it to the grate inside the combustion chamber for burning. The heat released during combustion is directly radiated through the fireplace glass in a fan-shaped pattern, warming the room containing the pellet fireplace. The high-temperature flue gas generated by burning the wood inside the combustion chamber enters the exhaust box through a waste gas pipe. This high-temperature flue gas is ultimately extracted by the exhaust fan and discharged to the outside. In the waste gas pipe, the high-temperature flue gas heats the air in the hot air duct through heat conduction. This hot air is driven upwards by a heating fan within the hot air duct. Valves distribute the direction and flow of the hot air, thereby regulating the airflow and heating temperature. Finally, the regulated hot air is delivered to either the upper hot air outlet 101 or the front hot air outlet 103.

[0050] The front hot air outlet directly supplies hot air to the room where the air-heated pellet fireplace body 1 is located for heating. The two upper hot air outlets are connected to the hot air delivery pipes respectively. The delivery fan is set in the outlet end of the hot air delivery pipe. The hot air, powered by the delivery fan and controlled by the flow path, is delivered to each room through the hot air delivery pipe, and finally the whole house is heated by heat convection.

[0051] In this specification, the same or similar parts between the various embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

[0052] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
