Technical Field

[0001] This invention relates to the field of fresh air system technology, and more particularly to a fresh air device. Background Technology

[0002] A fresh air system can bring fresh outdoor air into the room and at the same time filter and exhaust stale indoor air to the outside, thus replacing the indoor air with fresh air.

[0003] After the outdoor fresh air and the indoor stale air exchange heat through the heat exchanger, the temperature of the fresh air entering the room can be closer to the indoor temperature.

[0004] However, fresh air is usually not treated before entering a room, which can negatively impact human health. Additionally, the filter and heat exchanger in a fresh air system form an angle, causing significant noise and airflow loss as fresh air flows from the filter to the heat exchanger. Summary of the Invention

[0021] The air-assisted treatment box is equipped with multiple arc-shaped air guide plates. An arc-shaped air duct is formed between two adjacent arc-shaped air guide plates. One side of the arc-shaped air duct opens to the air inlet surface of the air-assisted treatment box, and the other side opens to the air outlet surface of the air-assisted treatment box.

[0022] In the above technical solution, the auxiliary function module is provided with a liquid supply chamber for supplying air handling liquid into the arc-shaped guide air duct.

[0023] In the above technical solution, a liquid supply chamber is formed at the top of the air-assisted treatment box;

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0038] Currently available fresh air systems typically do not treat the fresh air entering the room, which can negatively impact health. Furthermore, the angle between the filter and heat exchanger in these systems causes significant noise and airflow loss as fresh air flows from the filter to the heat exchanger. This invention addresses this issue by incorporating an auxiliary module between the filter and heat exchanger. This module treats the fresh air, making it cleaner, and guides its flow, allowing it to smoothly transition from one side of the filter to the other, reducing airflow loss and noise during intake.

[0039] The following is in conjunction with the appendix Figure 1-3 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0040] An embodiment of the present invention proposes a method such as Figures 1-3 The fresh air system shown includes:

[0041] The base 1 has multiple mounting positions, with a first mounting position and a second mounting position formed on the upper part of the base; wherein...

[0042] The first installation position forms a first accommodating chamber for installing the filter 2;

[0043] The second mounting position forms a second accommodating chamber for mounting the heat exchanger 3;

[0044] The base forms an angled space 4 between the first accommodating chamber and the second accommodating chamber. The base forms a third mounting position in the angled space 4. The third mounting position serves as a reserved position for the optional and detachable installation of auxiliary function modules 5.

[0045] Specifically, the auxiliary function module 5 has a flow guiding function. Its overall shape is adapted to the structure of the angled space 4. Its interior is designed to guide the air discharged from the filter 2 so that the air can smoothly transition from the filter 2 to the heat exchanger 3.

[0046] In this embodiment of the invention, an auxiliary function module 5 is set in the space 4 between the filter 2 and the heat exchanger 3 to process the fresh air, making the fresh air entering the room cleaner. At the same time, the auxiliary function module 5 can also guide the fresh air, so that the fresh air can flow smoothly from one side of the filter 2 to the other side of the heat exchanger 3, thereby reducing the loss of air volume in the base and reducing the noise generated by the fresh air unit when introducing fresh air.

[0047] When the auxiliary function module 5 is not installed in the base 1, the flow path of the fresh air in the base 1 is as follows: Figure 1 As shown by the arrows, the airflow path within the base 1 after the auxiliary function module 5 is installed is as follows: Figure 2 As shown by the arrow in the image.

[0048] In any of the above embodiments, the auxiliary function module 5 has an air auxiliary treatment function, which has at least one of a humidification function, an air freshening function, and a sterilization and disinfection function.

[0049] In any of the above embodiments, an auxiliary return air inlet is also formed on the top of the base, so that the indoor return air can enter the angled space 4 from the auxiliary return air inlet. Since the return air temperature at the auxiliary return air inlet is higher, the higher temperature return air can be mixed with the fresh air before entering the heat exchanger 3, thereby avoiding condensation on the surface of the heat exchanger.

[0050] In any of the above embodiments, a fourth mounting position is formed at the lower part of the base for mounting the fan assembly; a connecting part is provided between the first mounting position and the second mounting position of the base, and an auxiliary air outlet is formed in the connecting part. When the fresh air device only needs to perform sterilization or humidification, the auxiliary air outlet can allow the air entering the angled space 4 from the auxiliary return air inlet to be directly sent into the room by the fan assembly through the auxiliary air outlet under the action of the fan assembly.

[0051] In any of the above embodiments, the auxiliary return air inlet and the auxiliary air outlet are each provided with an auxiliary damper, so that the auxiliary return air inlet and the auxiliary air outlet can be opened and closed as needed.

[0052] In any of the above embodiments, the auxiliary function module 5 includes multiple arc-shaped airflow guide ducts 51, wherein one end of the arc-shaped airflow guide duct 51 opens to the filter 2 side and the other end opens to the heat exchanger 3 side. When the fresh air device introduces fresh air, the fresh air first enters the base 1 through the fresh air pipe on the base 1 and comes into contact with the filter 2. Then, the fresh air passes through the filter 2 and comes into contact with the auxiliary function module 5 before flowing into the arc-shaped airflow guide duct 51. After being guided by the arc-shaped airflow guide duct 51, it flows into the heat exchanger 3, thereby achieving the effect of guiding the fresh air. In this embodiment of the invention, by setting multiple airflow guide ducts 51, the fresh air can be divided into multiple parts and guided sequentially, thereby improving the guiding effect.

[0053] In any of the above embodiments, to further improve the airflow guiding effect, multiple arc-shaped airflow guiding ducts 51 are distributed from the narrow opening side to the wide opening side of the angled space 4, and the flow path of the arc-shaped airflow guiding duct 51 located on the wide opening side is longer than that of the arc-shaped airflow guiding duct 51 located on the narrow opening side. In this embodiment of the invention, the arc-shaped airflow guiding ducts 51 are arranged in the above manner because the space between the filter 2 and the heat exchanger 3 for placing the air auxiliary filter module 5 is a V-shaped space (since there is an angle between the filter 2 and the heat exchanger 3, a V-shaped space is formed between them). This allows the fresh air flowing out of the filter 2 to be completely guided by the arc-shaped airflow guiding ducts 51 before flowing into the heat exchanger 3, thereby avoiding the loss of fresh air volume and reducing noise.

[0054] In any of the above embodiments, in order to allow fresh air to flow more quickly from one side of the filter 2 to the other side of the heat exchanger 3, the width of the arc-shaped guide duct 51 on the wide side is smaller than the width of the arc-shaped guide duct 51 on the narrow side. Since a longer duct path results in a longer airflow time, the width of the longer arc-shaped guide duct 51 is set relatively small in this embodiment to overcome the problem of excessively long fresh air flow time caused by an excessively long duct path. This ensures that fresh air can be quickly discharged into the room.

[0055] In any of the above embodiments, the included angle space 4 formed between the filter 2 and the heat exchanger 3 mentioned above is an acute angle with the opening facing upwards.

[0056] In any of the above embodiments, such as Figure 3 As shown, the aforementioned auxiliary function module 5 is an air auxiliary treatment box installed at the position of the included space 4;

[0057] The air-assisted treatment box is a triangular box, which includes an air inlet surface that is close to or attached to the filter 2 and an air outlet surface that is close to or attached to the heat exchanger 3.

[0058] The air-assisted treatment box is equipped with multiple arc-shaped air guide plates 52. An arc-shaped air duct 51 is formed between two adjacent arc-shaped air guide plates 52. One side of the arc-shaped air duct 51 opens to the air inlet surface of the air-assisted treatment box, and the other side opens to the air outlet surface of the air-assisted treatment box.

[0059] When the fresh air unit is running, the fresh air discharged from the filter 2 side enters the arc-shaped guide air duct 51 through the air inlet on the air inlet surface of the air auxiliary treatment box, and is discharged into the heat exchanger 3 along the guide air direction of the arc-shaped guide air duct 51 to exchange heat with the heat exchanger.

[0060] In any of the above embodiments, such as Figure 3 As shown, the auxiliary function module 5 mentioned above is also provided with a liquid supply chamber 53, which is used to supply air treatment liquid into the arc-shaped air guide duct 51. It is worth noting that the air treatment liquid mentioned above can be any liquid that can treat air, such as disinfectant, cleaning water, or bactericide. The specific composition of the liquid is not limited in this embodiment of the invention.

[0061] Specifically, a liquid supply chamber 53 is formed between the air guide plate 52 located at the top of the air-assisted treatment box and the inner wall of the air-assisted treatment box;

[0062] The top of the air-assisted treatment box is rotatably equipped with a sealing cover 54, which can be rotated to open or close the liquid supply chamber 53.

[0063] In any of the above embodiments, the air handling module 5 is provided with multiple liquid-absorbing cores 55 made of capillary material, and each arc-shaped air duct 51 is provided with at least one liquid-absorbing core 55.

[0064] One end of the liquid-absorbing core 55 extends into the arc-shaped airflow duct 51, and the other end is immersed in the liquid supply chamber 53. When fresh air flows through the arc-shaped airflow duct 51, the flowing fresh air can adsorb the liquid in the liquid-absorbing core into the air and mix it with the fresh air, thereby achieving the effect of air treatment.

[0065] In any of the above embodiments, both the first and second accommodating chambers have openings on the sides of the base for assembling and disassembling the filter 2 and heat exchanger 3, and the included space 4 has an opening on the top of the base for assembling and disassembling the auxiliary functional module 5. This facilitates the assembly and disassembly of the filter 2, heat exchanger 3, and auxiliary functional module 5.

[0066] In summary, by setting an air-assisted filtration module 5 between the filter 2 and the heat exchanger 3 in the base 1, the fresh air can be treated and the direction of fresh air flow can be guided, thereby making the fresh air entering the room cleaner, reducing the loss of fresh air volume and reducing the noise of the base.

The first shaft end is driven and connected to the fresh air fan blade 621, and the second shaft end is driven and connected to the stale air fan blade 631. The fresh air device also includes a detection element and a fresh air electrical box 65. The detection element is used to detect the quality of fresh air.
