Description

Technical Field

[0001] This utility model belongs to the field of building ventilation technology, and in particular relates to a ventilation structure for energy-saving buildings. Background Technology

[0002] The ventilation structure of an energy-efficient building is a device that promotes air circulation with low energy consumption. In energy-efficient buildings, good ventilation is often considered to replace indoor air and ensure the comfort of the living space.

[0003] Existing energy-efficient buildings employ a split-type air intake and exhaust circulation design for their ventilation systems. This design uses different structures to achieve air intake and exhaust within the building, making the internal structure relatively complex and inconvenient to maintain. Utility Model Content

[0004] The technical problem to be solved by this utility model is to promote air circulation inside the building, improve the efficiency of air exchange between the inside and outside of the building, and facilitate maintenance through an integrated air intake and exhaust ventilation structure.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a ventilation structure for an energy-saving building, comprising a ventilation duct body, an exhaust pipe connected to one side wall of the ventilation duct body, and further comprising a connecting pipe, an inlet pipe, a partition, a negative pressure guiding component, and an auxiliary air intake mechanism. The partition is fixedly connected to the middle of the interior of the ventilation duct body and divides the interior of the ventilation duct body into an exhaust chamber and an inlet chamber. The exhaust pipe is connected to the exhaust chamber. The negative pressure guiding component is disposed in the exhaust chamber. The inlet pipe is disposed at one end of the ventilation duct body. The connecting pipe is fixedly connected to the other end of the ventilation duct body. The inlet pipe and the connecting pipe are connected through the ventilation duct body for circulating gas. The auxiliary air intake mechanism is installed inside the inlet pipe for auxiliary air intake into the ventilation duct body.

[0006] Furthermore, the air inlet pipe is symmetrically distributed at one end of the ventilation duct body with the partition as the center, and the connecting pipe is symmetrically distributed at the other end of the ventilation duct body with the partition as the center. The connecting pipe and the air inlet pipe on the same side are respectively connected to the air inlet chamber and the exhaust chamber.

[0007] Furthermore, the auxiliary air intake mechanism includes an air intake fan, which is fixedly connected inside the air intake pipe.

[0008] Furthermore, the negative pressure guiding assembly includes a baffle and a guide plate. One end of the baffle is fixedly connected to the side wall of the partition and the baffle is located in the middle of the air outlet pipe. The guide plate is fixedly connected between the opposite inner side walls of the ventilation pipe body and close to one end of the air inlet pipe.

[0009] Furthermore, the guide vane is inclined and the inclined guide vane is arranged at uniform intervals along the height direction of the air intake cavity, and the end of the baffle near the connecting pipe is inclined.

[0010] Furthermore, a partition mesh is inserted into the air inlet cavity, one end of which extends through the side wall of the ventilation duct to the outside of the ventilation duct, and a positioning plate is fixedly connected to the end of the partition mesh extending out of the ventilation duct.

[0011] The beneficial effects of this utility model after adopting the above structure are as follows: For the air exchange and flow inside and outside the energy-saving building, the ventilation duct connects the ambient air inside and outside the building. Natural wind or active air intake is used to promote the air to pass through the ventilation duct. The ventilation duct is divided into an air intake chamber and an exhaust chamber by a partition. In the exhaust chamber, the gas flow is guided by a negative pressure guide component. When the gas passes through the exhaust chamber quickly and is discharged through the exhaust pipe, the connecting pipe at one end of the exhaust chamber generates negative pressure, which draws in the indoor air and discharges it. At the same time, the air inside the air intake chamber is filtered by a mesh and then introduced into the building through the connecting pipe at one end of the air intake chamber, realizing the air flow in and out of the building.

[0017] like Figure 1-3As shown, a ventilation structure for an energy-efficient building includes a ventilation duct 1, with an exhaust pipe 2 connected to one side wall of the ventilation duct 1. It also includes a connecting pipe 3, an air inlet pipe 4, a partition 5, a negative pressure guiding component 6, and an auxiliary air intake mechanism 7. The partition 5 is fixedly connected to the middle of the ventilation duct 1, dividing the interior of the ventilation duct 1 into an exhaust chamber 8 and an air inlet chamber 9. The exhaust pipe 2 is connected to the exhaust chamber 8. The negative pressure guiding component 6 is located within the exhaust chamber 8. The air inlet pipe 4 is located at one end of the ventilation duct 1, and the connecting pipe 3 is fixedly connected to the other end of the ventilation duct 1. The air inlet pipe 4 and the connecting pipe 3 are connected through the ventilation duct 1 for ventilation... The ventilation duct 1 is equipped with an auxiliary air intake mechanism 7 installed inside the air intake pipe 4. This mechanism assists in the intake of air into the ventilation duct 1. Outdoor air enters the exhaust chamber 8 and the air intake chamber 9 through the end of the ventilation duct 1 connected to the air intake pipe. The air in the exhaust chamber 8 is guided by the negative pressure guide component 6 and then discharged through the exhaust pipe 2. This creates a negative pressure at the end of the exhaust chamber 8 near the connecting pipe 3. The connecting pipe 3 connected to the exhaust chamber 8 draws out indoor air, while air in the lower air intake chamber 9 is introduced into the room, thus achieving indoor and outdoor air circulation. When the natural air volume is small, the auxiliary air intake mechanism 7 increases the air intake of the ventilation duct 1, improving the ventilation efficiency.

[0018] like Figure 2 and Figure 3 As shown, in order to achieve indoor and outdoor air circulation and separate the air intake and exhaust flow, the air intake pipe 4 is symmetrically distributed at one end of the ventilation pipe body 1 with the partition 5 as the center, and the connecting pipe 3 is symmetrically distributed at the other end of the ventilation pipe body 1 with the partition 5 as the center. The connecting pipe 3 and the air intake pipe on the same side are connected to the air intake chamber 9 and the exhaust chamber 8 respectively. The connecting pipe 3 and the air intake pipe 4, which are symmetrically distributed at both ends of the ventilation pipe body 1, are connected to the exhaust chamber 8 and the air intake chamber 9 respectively in the horizontal direction, so that the indoor and outdoor air intake and exhaust flow are separated.

[0019] like Figure 2 As shown, in order to achieve the extraction of indoor air from the ventilation duct 1 and make the exhaust chamber 8 near the connecting pipe 3 in a negative pressure state, the negative pressure guiding component 6 includes a baffle 11 and a guide plate 12. One end of the baffle 11 is fixedly connected to the side wall of the partition 5 and the baffle 11 is located in the middle of the air outlet pipe 2. The guide plate 12 is fixedly connected between the opposite inner side walls of the ventilation duct 1 and near the end of the air inlet pipe. The guide plate 12 is inclined and the inclined guide plate 12 is evenly spaced along the height direction of the air inlet chamber. The end of the baffle 11 near the connecting pipe 3 is inclined. When the exhaust chamber 8 takes in air through the air inlet pipe 4, the flowing air is guided to the air outlet pipe 2 by multiple sets of guide plates 12. When the gas flows quickly and is discharged from the air outlet pipe 2, the side of the exhaust chamber near the connecting pipe 3 is in a negative pressure state. The air inlet discharged through the air outlet pipe 2 drives the indoor air to be extracted. The baffle 11 blocks the air inlet on the side of the guide plate 12 and guides the air extraction on the side of the connecting pipe 3.

[0020] like Figure 1 and Figure 2 As shown, in order to increase the air intake of the ventilation duct 1 and improve the air conversion efficiency, the auxiliary air intake mechanism 7 includes an air intake fan 10, which is fixedly connected to the air intake duct 4. The fan blows air into the exhaust chamber 8 and the air intake chamber 9 to increase the ventilation volume and promote air flow.

[0021] The air inlet cavity 9 is equipped with a mesh screen 13. One end of the mesh screen 13 extends through the side wall of the ventilation duct 1 to the outside of the ventilation duct 1. The end of the mesh screen 13 extending out of the ventilation duct 1 is fixedly connected to a positioning plate 14. The mesh screen 13 plays a filtering role in the air inlet cavity 9, filtering the air entering the room. The mesh screen 13 is bolted to the bottom wall of the ventilation duct 1 through the positioning plate 14, which is convenient for disassembly, cleaning and maintenance.

[0022] In actual use, the operator installs the device on the outside of the building and connects the upper and lower symmetrical connecting pipes 3 to the indoor air intake pipe and the air inlet pipe 4 respectively.

[0023] In use, the end of the ventilation duct 1 near the air inlet duct 4 can be filled with natural air or with air intake fan 10. When the exhaust chamber 8 is filled with air through the air inlet duct 4, the flowing air is guided to the exhaust pipe 2 by multiple sets of guide plates 12. When the gas flows quickly and is discharged from the exhaust pipe 2, the side of the exhaust chamber near the connecting pipe 3 is in a negative pressure state. The air inlet discharged through the exhaust pipe 2 drives the indoor air to be drawn out. The baffle 11 blocks the air inlet on the side of the guide plate 12 and guides the air exhaust on the side of the connecting pipe 3.

[0024] At the same time, air enters the air intake chamber 9, is filtered by the filter screen, and is then introduced into the room through the lower connecting pipe 3.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
