Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline systems, in particular to a lintel joint of a ventilation duct. Background Art

[0002] With the improvement of housing quality, household fresh air systems are receiving more and more attention. Household fresh air systems are equipped with fans, filters, air ducts, air inlets and outlets and other equipment and facilities to continuously and controllably deliver purified air into the room, bringing better ventilation effects and improving hygiene.

[0003] However, due to the limitations of the building structure, the air ducts of most fresh air systems need to cross beams. Currently, there are generally two solutions for air ducts crossing beams:

[0004] 1. Beam-through setting;

[0005] 2. Lintel setting.

[0006] When using a beam-through design, large-diameter ductwork passing through beams can affect the safety of the building structure. Furthermore, beam-through devices and other devices can increase duct system resistance, air leakage, and ventilation noise. When using a lintel design, the lintel has at least four 90-degree bends, creating significant duct resistance, poor ventilation, and increased noise. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a lintel joint that reduces the wind resistance and noise of the lintel of the air duct system without affecting the safety of the building structure.

[0008] The purpose of this utility model can be achieved through the following technical solutions:

[0009] A lintel joint for a ventilation duct, characterized in that it comprises a lintel air duct, an air inlet air duct and an air outlet air duct, the lintel air duct being fixedly connected to the lower side of a house crossbeam, the length direction of the lintel air duct being arranged obliquely to the length direction of the house crossbeam, the air inlet air duct and the air outlet air duct being fixedly connected to the roof on both sides of the house crossbeam respectively, and connecting air ducts are provided for smooth transition between the air inlet air duct and the lintel air duct, as well as between the air outlet air duct and the lintel air duct.

[0010] The lintel joint of this ventilation duct does not require drilling holes on the beams of the house, which does not affect the safety of the house structure; at the same time, the lintel joint can also greatly reduce the wind resistance generated in the process of crossing the beams of the house, making the air flow smoother and reducing noise.

[0011] In the above-mentioned lintel joint of the ventilation duct, the air inlet duct is parallel to the length direction of the house beam or perpendicular to the length direction of the house beam, and the air outlet duct is parallel to the length direction of the house beam or perpendicular to the length direction of the house beam.

[0012] The air inlet and outlet ducts have multiple implementation options:

[0013] 1. The air inlet and outlet ducts are parallel to the beams of the house;

[0014] 2. The air inlet duct is parallel to the beam of the house, and the air outlet duct is perpendicular to the beam of the house;

[0015] 3. The air inlet duct is perpendicular to the beam of the house, and the air outlet duct is parallel to the beam of the house;

[0016] 4. The air inlet and outlet ducts are both perpendicular to the beams of the house.

[0017] In the above-mentioned lintel joint of the ventilation duct, the angle α between the length direction of the lintel air duct and the length direction of the building beam is 45 degrees.

[0018] Installing the lintel air duct obliquely to the house beam can extend the connection length between the lintel air duct and the air inlet air duct or the air outlet air duct, making the connection between the air inlet air duct and the excess air duct or the air outlet air duct and the lintel air duct smoother, which is conducive to reducing wind resistance and energy consumption.

[0019] In the above-mentioned lintel joint of the ventilation duct, the height of the lintel air duct is smaller than its width and is flat.

[0020] Since it is generally necessary to install a suspended ceiling on the top of a house during renovation, and the house beams themselves are relatively high, the installation of a circular air duct will further increase the height of the house beams, resulting in a lower floor height of the entire house after the suspended ceiling is installed. This flat lintel air duct can minimize the vertical space occupied without affecting the air flow permeability, thereby reducing the negative impact of the lintel air duct on the floor height.

[0021] In the above-mentioned lintel joint of a ventilation duct, the lintel air duct includes a front air duct and a rear air duct, the front air duct and the rear air duct are plugged together, and the length of the lintel air duct is adjusted by adjusting the length of the connection between the front air duct and the rear air duct.

[0022] The above-mentioned adjustable length lintel air duct structure enables the lintel joint to adapt to house beams of different widths, thereby reducing the installation length required for the lintel air duct perpendicular to the house beam direction, making the lintel joint more adaptable and occupying less space.

[0023] In the above-mentioned lintel joint of a ventilation duct, the end of the rear air duct facing the front air duct is enlarged to form a plug-in portion, the front air duct can be inserted into the plug-in portion, and the front air duct can move relative to the rear air duct along the length direction of the lintel air duct. The front air duct and the rear air duct are both provided with mounting portions for fixing the front air duct and the rear air duct to the crossbeam of the house.

[0024] The mounting portion provided on this lintel joint can fix the front air duct and the rear air duct separately, ensuring that the assembled lintel joint can be firmly fixed on the crossbeam of the house, avoiding the front air duct and the rear air duct from shaking significantly due to the passage of high-speed airflow, which is beneficial to reducing noise; the plug-in portion formed by the expanded diameter can make the inner diameters of the front air duct and the rear air duct the same, avoiding the connection point having an obvious step surface when the airflow passes through, which is beneficial to reducing wind resistance.

[0025] In the above-mentioned lintel joint of the ventilation duct, a sealing groove is formed at the rear end of the front air duct, and a sealing ring is installed in the sealing groove. The sealing ring can seal between the outer wall of the front air duct and the inner wall of the plug-in part.

[0026] The cooperation between the sealing groove and the sealing ring can achieve sealing of the connection between the front air duct and the rear air duct to avoid air leakage.

[0027] In the above-mentioned lintel joint of the ventilation duct, the inner side wall of the plug-in portion and the inner side wall of the rear air duct body are connected via an inclined guide surface.

[0028] The design of the guide surface can avoid a relatively obvious step surface between the plug-in portion and the rear air duct body, which is beneficial to reducing wind resistance and noise.

[0029] Compared with the prior art, the technical effects of the present invention are:

[0030] The lintel joint of the utility model does not need to drill holes on the beams of the house, and does not affect the safety of the house structure; at the same time, the lintel joint can also greatly reduce the wind resistance generated in the process of crossing the beams of the house, making the air flow smoother and reducing the generation of noise.

DETAILED DESCRIPTION

[0040] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0041] The lintel joint of this ventilation duct includes a lintel air duct 1, an air inlet duct 2, and an air outlet duct 3. The lintel air duct 1 is fixedly connected to the underside of a house crossbeam 5, with the length of the lintel air duct 1 being arranged obliquely to the length of the house crossbeam 5. The air inlet duct 2 and the air outlet duct 3 are respectively fixedly connected to the roof 6 on either side of the house crossbeam 5. Connecting air ducts 4 smoothly transition between the air inlet duct 2 and the lintel air duct 1, and between the air outlet duct 3 and the lintel air duct 1. The lintel joint of this ventilation duct does not require drilling holes in the house crossbeam 5, which does not affect the safety of the house structure. It also significantly reduces wind resistance generated when crossing the house crossbeam 5, allowing for smoother airflow and reducing noise.

[0042] Furthermore, the included angle α between the length direction of the lintel duct 1 and the length direction of the house beam 5 is 45 degrees. Installing the lintel duct 1 obliquely relative to the house beam 5 can extend the connection length between the lintel duct 1 and the air inlet duct 2 or the air outlet duct 3, making the connection between the air inlet duct 2 and the excess air duct or the air outlet duct 3 and the lintel duct 1 smoother, thereby reducing wind resistance and lowering energy consumption.

[0043] Furthermore, the lintel air duct 1 is flat in shape, having a shorter height than its width. Since ceilings are commonly installed on the roof 6 during renovations, and the beams 5 are already quite high, installing a circular air duct would further increase the height of the beams 5, resulting in a lower floor height after the ceiling is installed. The flat lintel air duct 1 can minimize the vertical space occupied without affecting airflow, thus reducing the negative impact of the lintel air duct 1 on floor height.

[0044] like Figure 2 、 Figure 6 and Figure 8 As shown, the lintel air duct 1 includes a front air duct 11 and a rear air duct 12, and the front air duct 11 and the rear air duct 12 are plugged into each other, and the length of the lintel air duct 1 is adjusted by adjusting the length of the connection between the front air duct 11 and the rear air duct 12; the end of the rear air duct 12 facing the front air duct 11 is enlarged to form a plug-in portion 121, and the front air duct 11 can be inserted into the plug-in portion 121, and the front air duct 11 can move relative to the rear air duct 12 along the length direction of the lintel air duct 1, and the front air duct 11 and the rear air duct 12 are provided with a mounting portion 13 for fixing the front air duct 11 and the rear air duct 12 to the house beam 5; the inner side wall of the plug-in portion 121 and the inner side wall of the rear air duct body 122 are connected by an inclined guide surface 123. The above-mentioned adjustable length lintel air duct 1 structure enables the lintel joint to adapt to house beams 5 of different widths, thereby reducing the installation length required for the lintel air duct 1 in the direction perpendicular to the house beam 5, making the lintel joint more adaptable and occupying less space; the mounting portion 13 provided on the lintel joint can fix the front air duct 11 and the rear air duct 12 separately, ensuring that the assembled lintel joint can be firmly fixed on the house beam 5, avoiding the front air duct 11 and the rear air duct 12 from shaking significantly due to the passage of high-speed airflow, which is beneficial to reducing noise; the plug-in portion 121 formed by the expanded diameter can make the inner diameters of the front air duct 11 and the rear air duct 12 the same, avoiding the connection point having an obvious step surface when the airflow passes through, which is beneficial to reducing wind resistance; the design of the above-mentioned guide surface 123 can avoid a relatively obvious step surface between the plug-in portion 121 and the rear air duct main body 122, which is beneficial to reducing wind resistance and noise.

[0045] Furthermore, a sealing groove 111 is formed at the rear end of the front air duct 11, and a sealing ring 14 is installed in the sealing groove 111. The sealing ring 14 can seal between the outer wall of the front air duct 11 and the inner wall of the plug-in portion 121. The sealing groove 111 and the sealing ring 14 cooperate to achieve a seal at the connection between the front air duct 11 and the rear air duct 12 to prevent air leakage.

[0046] The air inlet duct 2 and the air outlet duct 3 have at least the following embodiments:

[0047] In the first embodiment, the air inlet duct 2 and the air outlet duct 3 are both parallel to the building beam 5;

[0048] Example 2: The air inlet duct 2 is parallel to the house beam 5, and the air outlet duct 3 is perpendicular to the house beam 5;

[0049] Example 3: The air inlet duct 2 is perpendicular to the house beam 5, and the air outlet duct 3 is parallel to the house beam 5;

[0050] Embodiment 4: The air inlet duct 2 and the air outlet duct 3 are both perpendicular to the building beam 5.

[0051] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection defined by the claims of the present invention.
