Description

Technical Field

[0001] The utility model relates to the technical field of fresh air systems, in particular to a fresh air ventilation device with adjustable air intake volume. Background Art

[0002] Fresh air is widely used to improve indoor air quality. Traditional fresh air ventilation devices mostly adopt a single air inlet and multiple exhaust windows design. In order to ensure that there is enough space between the air inlet and each exhaust window to effectively arrange the filter structure, the existing multiple exhaust window fresh air fans usually require a larger casing width. Such a design not only takes up more space, but also limits the choice of equipment installation location, especially in urban residences with relatively tight space, this limitation is more obvious; in addition, in the existing technology, each exhaust window is often equipped with a separate fan and filter chamber. When a single fan is running, the corresponding filter chamber will be idle, occupying the internal space without playing a corresponding role, and after long-term operation, the status of each fan and filter element will be different, and the air pressure, air volume and cleanliness of the air discharged from each exhaust window will also be different, affecting the fresh air experience.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] A fresh air ventilation device with adjustable air intake, see Figure 1-5 , including a casing 1, a filter chamber 2 is arranged in the middle of the casing 1, and both sides of the filter chamber 2 are provided with a first side wall 21 and a second side wall 22 arranged perpendicular to each other, an air inlet 211 is opened on the surface of the first side wall 21, and an exhaust port 221 is opened on the surface of the second side wall 22; a square filter element 5 is arranged in the filter chamber 2, and two adjacent side walls of the square filter element 5 are respectively fitted with the first side wall 21 and the second side wall 22, and the air enters the filter cavity from the air inlet 211 and flows out of the filter cavity from the exhaust port 221. By arranging the square filter element 5 on the air circulation path, the dust in the air can be effectively filtered and the fresh air effect can be improved.

[0027] Partitions 3 are symmetrically arranged on both sides of the casing 1. The partitions 3 are connected to the outer wall of the filter chamber 2 and are provided with a notch 31 in the middle. The notch 31 is relatively connected to the air inlet 211; the partitions 3 extend to both sides of the filter chamber 2 and separate the exhaust chamber 12 and the air intake chamber 11 inside the casing 1. An air intake window 14 and an exhaust window 15 are respectively provided on the two opposite outer walls of the casing 1. A fan 4 connected to the air intake window 14 is provided in the casing 1. The exhaust side of the fan 4 faces the air intake chamber 11, and the exhaust window 15 is connected to the exhaust chamber 12.

[0028] The utility model arranges the filter chamber 2 between the two air inlet chambers 11 and the two exhaust chambers 12, and the air inlet chamber 11 and the exhaust chamber 12 are respectively located on the outside of the first side wall 21 and the second side wall 22 perpendicular to each other of the filter chamber 2, thereby shortening the vertical distance between the air inlet window 14 and the exhaust window 15 when the filter chamber 2 is arranged between the air inlet chamber 11 and the exhaust chamber 12, reducing the overall width layout of the casing 1, improving the aesthetics and flexibility of assembly, and enabling the casing 1 to be installed in a narrow space.

[0029] In some specific embodiments of the present invention, three square filter elements 5 are provided and arranged in parallel, and the square filter elements 5 separate the filter chamber 2 into triangular filter channels 23. The provision of the filter channels 23 allows gas to flow smoothly between the two sides of the filter chamber 2; an air inlet chamber 11 and an exhaust chamber 12 communicating with the filter chamber 2 are provided on both sides of the filter chamber 2, and multiple filter elements are integrated into a single filter chamber 2, so that air flowing in from both sides flows into the same filter chamber 2 for filtration and is discharged from the exhaust chambers 12 on both sides of the same filter chamber 2; the square filter elements 5 integrated into the filter chamber 2 are convenient for simultaneous replacement, improving the convenience of assembly and replacement. In addition, compared with separately providing filter chambers 2 on both sides, the volume occupied by the filter chamber 2 is reduced.

[0030] In this embodiment, two fans 4 can be started at the same time to achieve maximum air volume; a single fan 4 can also be started. When the single fan 4 is started, air enters the filter chamber 2 from the air inlet 211 on one side, is discharged into the exhaust cavity 12 from the exhaust ports 221 on both sides of the filter chamber 2, and is finally discharged from the exhaust windows 15, ensuring that in the state of a single fan 4, the pressure of the fresh air discharged from the two exhaust windows 15 on both sides is balanced and the exhaust volume is stable; compared to the traditional long pipeline transportation, where multiple exhaust windows 15 are located at different positions of the entire transportation pipeline, the filter chamber can stabilize and balance the air flow, so that the exhaust pressure, exhaust particle content and exhaust volume of the two exhaust windows 15 are basically the same, thereby improving the comfort of fresh air intake.

[0031] In some specific embodiments of the present invention, Figure 1 、 24. An air shell 6 is provided in the air inlet cavity 11. The air shell 6 includes a triangular portion 61 and a square portion 62 that are interconnected. The partition 3 is integrally formed as the inclined side surface of the triangular portion 61, that is, the partition 3 is the inclined side surface of the air shell 6. A through hole 621 is provided on the top surface of the square portion 62. A fan 4 is provided above the square portion 62. The exhaust side of the fan 4 is connected to the through hole 621, and the top surface of the fan 4 is flush with the top surface of the triangular portion 61. The air inlet side of the fan 4 is connected to the air inlet window 14. The air discharged from the exhaust side of the fan 4 passes through the square portion 62 and the triangular portion 61 in sequence and enters the air inlet cavity 11. This structure of the fan 4 and air shell 6 stacked up and down fully utilizes the longitudinal space in the housing 1 without increasing the length and width of the housing 1, thereby improving the integration. The fan 4 can be fixed on the top of the square portion 62. The structure of the air shell 6 achieves a fixing effect on the fan 4, thereby improving the safety of the device.

[0032] In addition, a sound-absorbing pad 7 with a central opening is provided between the fan 4 and the square portion 62, and the opening of the sound-absorbing pad 7 is relatively connected to the through hole 621; by providing the sound-absorbing pad 7, the operating noise of the fan 4 is reduced, the overall quietness of the fresh air ventilation device is improved, and the user's comfort is improved.

[0033] A control room 13 is provided on one side of the housing 1 . The control room 13 is isolated from the air inlet chamber 11 and the air outlet chamber 12 . The control hardware of the device is installed in the control room 13 .

[0034] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
