Description

Technical Field

[0001] This utility model relates to the field of pellet heating stove technology, and more specifically, to an inlet / outlet separation valve and a composite flue for a pellet heating stove. Background Technology

[0002] Pellet heaters are a type of high-efficiency, environmentally friendly, and energy-saving heating equipment. They use environmentally friendly, renewable, and recyclable pellets as fuel, and produce no smoke, dust, or odor after combustion, creating a healthy and fresh indoor environment.

[0003] Traditional pellet stoves have the following drawbacks: Their operation typically involves introducing indoor air into the furnace for combustion and venting the exhaust gases outdoors, creating a negative pressure zone inside the room. To maintain this pressure balance, cooler outdoor air continuously seeps into the room through gaps in doors and windows. This not only wastes energy but also results in uneven temperature distribution within the room, with areas near doors and windows experiencing frequent air exchange being relatively cooler, while the area around the furnace is relatively warmer. This uneven temperature distribution affects heating comfort and may increase energy consumption, reducing the overall energy efficiency of the stove. Therefore, a pellet stove with a separate inlet / outlet valve and composite flue is needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an inlet / outlet separation valve and a composite flue for a pellet heating stove, which has the advantage of energy saving.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an inlet / outlet separation valve and composite flue for a pellet heating stove, comprising an inner tube, a separation valve fixedly sleeved on the outer side of the inner tube, an outer tube fixedly installed on the right side of the separation valve located outside the inner tube, a connecting pipe fixedly installed above the separation valve, a bent pipe fixedly installed above the connecting pipe, and a flue fan fixedly installed at the left end of the inner tube.

[0006] As a preferred embodiment of this utility model, the separation valve has an air inlet on its right side, the inner tube is located inside the air inlet, and the outer tube is fixedly connected to the right side of the air inlet.

[0007] As a preferred embodiment of this utility model, the separation valve has an internal cavity, and an air outlet is provided above the cavity. The connecting pipe is fixedly connected above the air outlet.

[0008] As a preferred embodiment of this utility model, a support plate is uniformly and fixedly installed inside the cavity, and the other end of the support plate is fixedly connected to the outside of the inner tube.

[0009] As a preferred embodiment of this utility model, the outer side of the bend is corrugated, and the other end of the bend is connected to the gas supply port of the combustion chamber.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention draws in outdoor air through an external pipe into the combustion chamber, thus avoiding direct consumption of indoor air. Compared to traditional pellet heaters, this pellet heater uses an intake / exhaust separation valve and a composite flue to directly draw in outdoor air, resulting in faster heating and eliminating uneven temperature distribution, thus achieving energy savings. This invention achieves both intake and exhaust functions simply by opening a hole in the wall to connect to the outside, making it simple, convenient, and easy to use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 6As shown, this utility model provides an inlet / outlet separation valve and composite flue for a pellet heating stove, including an inner pipe 1, a separation valve 2 fixedly sleeved on the outside of the inner pipe 1, an outer pipe 3 fixedly installed on the right side of the separation valve 2 located outside the inner pipe 1, a connecting pipe 4 fixedly installed above the separation valve 2, a bent pipe 5 fixedly installed above the connecting pipe 4, and a flue fan 6 fixedly installed on the left end of the inner pipe 1.

[0021] In use, the separation valve 2 is installed above the outer shell of the pellet heater, so that the left end of the inner pipe 1 is directly connected to the exhaust fan 6 of the heater, and the outer pipe 3 is connected to the air inlet of the pellet heater. The right ends of the outer pipe 3 and the inner pipe 1 are placed outdoors, so that gas is supplied through the gap between the outer pipe 3 and the inner pipe 1, allowing outdoor gas to enter the cavity 8 through the air inlet 7. The outer pipe 3 is connected to the separation valve 2, which is equipped with a connecting pipe 4 and a bend 5 that connect to the gas supply port of the combustion chamber. Outdoor air is drawn in through the outer pipe 3 for combustion support. The inner pipe 1 is longer than the outer pipe 3 and is responsible for discharging the exhaust gas generated in the pellet heater to the outside under the action of the exhaust fan 6. The gases in the inner pipe 1 and the outer pipe 3 do not interfere with each other and work independently.

[0022] The combustion chamber draws in outdoor air through the outer pipe 3, thus avoiding direct consumption of indoor air. Compared with traditional pellet heaters, this pellet heater uses an intake / exhaust separation valve and a composite flue to directly draw in outdoor air, which allows for faster heating of the room temperature and avoids uneven temperature distribution caused by localized hot and cold areas, thereby achieving energy conservation.

[0023] By creating a hole in the wall to connect with the outside, both air intake and exhaust functions can be achieved, which is simple, convenient, and easy to use.

[0024] The separation valve 2 has an air inlet 7 on its right side, the inner pipe 1 is located inside the air inlet 7, and the outer pipe 3 is fixedly connected to the right side of the air inlet 7.

[0025] Outdoor air is drawn into the cavity 8 through the gap between the outer pipe 3 and the inner pipe 1 via the air inlet 7, and then injected into the combustion chamber through the separation valve 2.

[0026] The separation valve 2 has a cavity 8 inside, and an air outlet 9 is provided above the cavity 8. The connecting pipe 4 is fixedly connected above the air outlet 9.

[0027] By opening a cavity 8 inside the separation valve 2, air can be directly introduced into the air outlet 9 through the air inlet 7.

[0028] The cavity 8 has a support plate 10 uniformly fixedly installed inside, and the other end of the support plate 10 is fixedly connected to the outside of the inner tube 1.

[0029] The support plate 10 can fix the inner tube 1, thereby facilitating the discharge of exhaust gas generated in the combustion chamber through the inner tube 1.

[0030] The outer side of the bend 5 is provided with corrugations 11, and the other end of the bend 5 is connected to the gas supply port of the combustion chamber.

[0031] The corrugated 11 design gives the bend 5 greater bending capacity and adaptability, allowing it to accommodate complex pipe layouts; this makes the bend 5 easier to install and connect, reducing construction difficulty and cost.

[0032] Working principle and usage process of this utility model:

[0033] In use, the separation valve 2 is installed above the outer shell of the pellet heater, so that the left end of the inner pipe 1 is directly connected to the exhaust fan 6 of the heater, and the outer pipe 3 is connected to the air inlet of the pellet heater. The right ends of the outer pipe 3 and the inner pipe 1 are placed outdoors, so that gas is supplied through the gap between the outer pipe 3 and the inner pipe 1, allowing outdoor gas to enter the cavity 8 through the air inlet 7. The outer pipe 3 is connected to the separation valve 2, which is equipped with a connecting pipe 4 and a bend 5 that connect to the gas supply port of the combustion chamber. Outdoor air is drawn in through the outer pipe 3 for combustion support. The inner pipe 1 is longer than the outer pipe 3 and is responsible for discharging the exhaust gas generated in the pellet heater to the outside under the action of the exhaust fan 6. The gases in the inner pipe 1 and the outer pipe 3 do not interfere with each other and work independently.
