Description

Technical Field

[0001] This utility model relates to the field of exhaust duct manufacturing, and in particular to a smoke-preventing guide component. Background Technology

[0002] In residential construction, centralized exhaust systems typically use direct exhaust ducts. Each household connects its range hood to the exhaust port via a pipe, allowing the fumes to be discharged through the duct. While simple, this method has several drawbacks: First, as the fumes from each household rise along the duct, fumes from lower-level households can backflow through the exhaust ports onto higher-level households, polluting their indoor air.

[0003] In existing technologies, a secondary exhaust duct is set in the direct exhaust duct to solve the problem of smoke cross-contamination. However, adding a secondary exhaust duct increases the material cost, and the secondary exhaust duct is installed after the main exhaust duct is formed, which makes construction more difficult and leaves gaps that can cause smoke cross-contamination. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a smoke-proof guide component that achieves layered management of smoke through upper and lower auxiliary exhaust ducts, effectively solving the problem of smoke odor mixing between floors. It also saves material costs by using the wall to enclose the main exhaust duct, reduces construction difficulty, and prevents smoke from mixing through gaps.

[0005] The objective of this utility model is achieved through the following technical solution.

[0006] A smoke-proof guide component includes an outer vertical plate and an inner vertical plate. The outer vertical plate is connected to a wall to form a vertically continuous main exhaust duct. The outer and inner vertical plates together form an upper and lower secondary exhaust duct on the same axis. The upper secondary exhaust duct has an opening at the top and is sealed at the bottom by a guide plate. The lower secondary exhaust duct is a vertically continuous exhaust duct with an exhaust port at the top and an opening at the bottom, which communicates with the main exhaust duct. An air inlet for the secondary exhaust duct is provided on the outer vertical plate, located above the guide plate. The smoke-proof guide component is installed floor by floor. The bottom opening of the lower secondary exhaust duct of the smoke-proof guide component of the upper floor is connected to the top opening of the upper secondary exhaust duct of the smoke-proof guide component of the lower floor to form a secondary exhaust duct.

[0007] The outer vertical plate is connected to the inside corner of the wall, and the exhaust port of the secondary exhaust duct is located at the reserved exhaust hole on the floor.

[0008] The upper section auxiliary exhaust duct guide plate is located above the exhaust port of the lower section auxiliary exhaust duct and is inclined upward along the exhaust direction of the lower section auxiliary exhaust duct.

[0009] The cross-sectional shape of the secondary exhaust duct is triangular or rectangular.

[0010] The main exhaust duct has a triangular or rectangular cross-sectional shape.

[0011] The smoke-proof and smoke-guiding component is integrally formed.

[0012] The smoke-proof diversion component is connected between the upper and lower floors through a through-hole.

[0013] The smoke-proof diversion component is connected to the wall surface by filling with sealing mortar.

[0014] Compared with the prior art, the advantages of this utility model are as follows: This utility model forms an independent exhaust component for the secondary exhaust duct by integrally molding the outer vertical plate and the inner vertical plate, which reduces the construction difficulty and does not produce gaps or cross-contamination of smoke. When the smoke enters the secondary exhaust duct through the air inlet, due to the sealing effect of the bottom guide plate, the smoke can only flow into the main exhaust duct through the exhaust port of the secondary exhaust duct along the direction of the guide plate and be discharged. Each secondary exhaust duct is independent of each other and will not cross-contamination of smoke. The use of the wall to enclose the main exhaust duct saves material costs.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] A smoke-proof guide component includes an outer vertical plate and an inner vertical plate. The outer vertical plate is connected to a wall to form a vertically continuous main exhaust duct. The outer and inner vertical plates together form an upper and lower secondary exhaust duct on the same axis. The upper secondary exhaust duct has an opening at the top and is sealed at the bottom by a guide plate. The lower secondary exhaust duct is a vertically continuous exhaust duct with an exhaust port at the top and an opening at the bottom, which communicates with the main exhaust duct. An air inlet for the secondary exhaust duct is provided on the outer vertical plate, located above the guide plate. The smoke-proof guide component is installed floor by floor. The bottom opening of the lower secondary exhaust duct of the smoke-proof guide component of the upper floor is connected to the top opening of the upper secondary exhaust duct of the smoke-proof guide component of the lower floor to form the entire secondary exhaust duct.

[0023] The outer vertical plate is connected to the inside corner of the wall, and the exhaust port of the secondary exhaust duct is located at the reserved exhaust hole on the floor.

[0024] The upper section auxiliary exhaust duct guide plate is located above the exhaust port of the lower section auxiliary exhaust duct and is inclined upward along the exhaust direction of the lower section auxiliary exhaust duct.

[0025] The cross-sectional shape of the secondary exhaust duct is triangular or rectangular.

[0026] The main exhaust duct has a triangular or rectangular cross-sectional shape.

[0027] The smoke-proof and smoke-guiding component is integrally formed.

[0028] The smoke-proof diversion component is connected between the upper and lower floors through a through-hole.

[0029] The smoke-proof diversion component is connected to the wall surface by filling with sealing mortar.

[0030] like Figure 1 and 2 As shown, a smoke-preventing guide component is integrally formed from an outer vertical plate 1 and an inner vertical plate 2. The outer vertical plate 2 has a secondary exhaust duct inlet 3 on one side. After the smoke enters the upper secondary exhaust duct 5 through the inlet 3, the bottom of the upper secondary exhaust duct 5 is sealed by the guide plate 6. At this time, the smoke is discharged upward through the exhaust port of the upper secondary exhaust duct. Similarly, after the smoke of the next layer enters the lower secondary exhaust duct 7, it is discharged into the main exhaust duct 9 through the exhaust port 8 of the secondary exhaust duct under the action of the guide plate 6. This achieves independent stratified discharge of the upper and lower layers of smoke, thus playing a role in preventing smoke cross-contamination.

[0031] like Figure 5As shown, the working process is as follows: When this utility model is in use, the flue gas enters the upper auxiliary air duct through the air inlet. Since the bottom guide plate is in a sealed state, the flue gas can only be discharged upward through the upper auxiliary air duct. Similarly, the flue gas of the next floor enters through the lower auxiliary air duct. Under the action of the guide plate, the flue gas of the lower auxiliary air duct enters the main exhaust duct through the exhaust port of the lower auxiliary air duct and is discharged, thereby realizing the independent stratified discharge of flue gas between the upper and lower floors and achieving the effect of preventing cross-contamination of smoke. Example

[0032] like Figure 3 As shown, the outer vertical panel is a straight panel, which connects with the wall to form a main exhaust duct that runs vertically through the wall. The cross-section of the main exhaust duct is triangular. The inner vertical panel is an L-shaped panel, which connects with the outer vertical panel to form a secondary exhaust duct. The cross-section of the secondary exhaust duct is also triangular. Example

[0033] like Figure 4 As shown, the outer vertical panel is an "L" shaped panel, which connects with the wall to form a main exhaust duct that runs vertically through the wall. The cross-section of the main exhaust duct is rectangular. The inner vertical panel is an "I" shaped panel, which connects with the outer vertical panel to form a secondary exhaust duct. The cross-section of the secondary exhaust duct is triangular.
