Detailed Implementation

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Please see Figure 1This application provides an air conditioner 10, which is installed in a designated area and introduces airflow into the designated area to provide air conditioning, thereby improving the air quality in the designated area. The air conditioning effect includes, but is not limited to, temperature regulation, humidity regulation, fresh air supply, dust removal and sterilization, and airflow rate regulation.

[0031] Please refer to the following: Figure 1 and Figure 2 To facilitate the delivery of airflow to a designated area, the air conditioner 10 may include an air duct structure 11. The air duct structure 11 draws in airflow from the designated area, allowing the airflow to pass through a heat exchanger 12 within the air conditioner 10, thus enabling heat exchange between the airflow and the heat exchanger 12. After heat exchange, the airflow is delivered by the air duct structure 11 to the designated area. The airflow delivered by the air duct structure 11 then regulates the airflow in the designated area.

[0032] In order to improve the technical problem of the short air outlet distance of the air conditioner 10 in the prior art, the air duct structure 11 of this application is provided, and the air conditioner 10 adopting the air duct structure 11 of this application is provided.

[0033] The air duct structure 11 includes a main air duct structure 100 and a secondary air duct structure 200. The main air duct structure 100 is used to introduce airflow into a designated area to ensure sufficient airflow into the designated area, thereby ensuring effective air conditioning. The secondary air duct structure 200 is also used to introduce airflow into the designated area, and it strengthens the airflow exiting the main air duct structure 100, so that the airflow exiting the main air duct structure 100 can extend the flow distance, thereby improving the technical problem of the short air outlet distance of the air conditioner 10 in the prior art.

[0034] The main air duct structure 100 includes a first fan 120 and a first housing 110. The first housing 110 forms a first air duct 101 for air outlet, and the first fan 120 is disposed in the first air duct 101 to introduce airflow into the first air duct 101. During operation, the first fan 120 can draw in airflow from a designated area and then export the airflow from the first air duct 101 to the designated area. The secondary air duct structure 200 includes a second fan 220 and a second housing 210. The second housing 210 is disposed around the first housing 110, and the outer sides of the second housing 210 and the first housing 110 together form a second air duct 201, which surrounds the first air duct 101. The second fan 220 is disposed in the second air duct 201 to introduce airflow into the second air duct 201. During operation, the second fan 220 draws in airflow from a designated area and then exports the airflow from the second air duct 201 to the designated area. Since the second air duct 201 is arranged around the first air duct 101, the airflow exiting the second air duct 201 is arranged around the airflow exiting the first air duct 101. This allows the airflow exiting the second air duct 201 to strengthen the airflow exiting the first air duct 101, thereby extending the flow distance of the airflow exiting the first air duct 101 and achieving the purpose of long-distance air delivery.

[0035] As described above, when the air duct structure 11 is activated and in the air outlet state, the first fan 120 can draw airflow from the main air duct, and the second fan 220 can draw airflow from the second air duct 201. The airflow drawn from the second air duct 201 flows around the airflow drawn from the first air duct 101. Under the strengthening effect of the airflow drawn from the second air duct 201, the airflow drawn from the first air duct 101 is strengthened, thereby increasing the flow distance of the airflow drawn from the first air duct 101, thus extending the air outlet distance and achieving the purpose of a longer blowing distance. When this air duct structure 11 is applied to the air conditioner 10, it can improve the technical problem of short air outlet distance in the existing air conditioner 10.

[0036] It is worth noting that the second air duct 201 is arranged around the first air duct 101, as shown in the diagram. Figure 4 The outlet of the second air duct 201 forms a ring, and the ring-shaped outlet of the second air duct 201 is arranged around the first air duct 101. During the air discharge process of the second air duct 201, the second air duct 201 discharges air from the ring-shaped outlet, thereby making the airflow discharged by the second air duct 201 cylindrical, while the airflow discharged by the first air duct 101 is located inside the cylindrical airflow. That is, the airflow discharged by the second air duct 201 surrounds the airflow discharged by the first air duct 101, which can provide a strengthening effect to the airflow discharged by the first air duct 101, so as to extend the flow distance of the airflow discharged by the first air duct 101.

[0037] It should be noted that, in the embodiments of this application, the airflow drawn in by the second fan 220 also passes through the heat exchanger 12 of the air conditioner 10, thereby enabling the airflow discharged from the second air duct 201 to also have air conditioning function. Based on this, while keeping the airflow discharged from the first air duct 101 unchanged, adding a second air duct 201 to introduce airflow into a designated area increases the amount of airflow introduced into the designated area, thereby improving the air conditioning efficiency for that area. Furthermore, since the flow distance of the airflow discharged from the first air duct 101 is extended, long-distance airflow can be achieved, allowing the airflow used for air conditioning to quickly reach any position within the designated area, thus enabling rapid air conditioning of the entire designated area and further improving air conditioning efficiency.

[0038] To enhance the strengthening effect of the airflow from the second air duct 201 on the airflow from the first air duct 101, optionally, in some embodiments of this application, the diameter of the second air duct 201 gradually decreases along the air outlet direction. Based on this, the air pressure continuously increases as the airflow in the second air duct 201 flows towards the air outlet, forming a high-pressure, high-speed airflow when it exits from the second air duct 201. This high-speed, high-pressure airflow can create a pressure difference with the airflow from the first air duct 101, thereby enhancing the strengthening effect of the airflow from the second air duct 201 on the airflow from the first air duct 101. This allows the high-speed, high-pressure airflow to carry the airflow from the first air duct 101 to a farther location, thus increasing the flow distance of the airflow from the first air duct 101.

[0039] Of course, since the second air duct 201 is arranged around the first air duct 101, some of the airflow from the second air duct 201 can be mixed into the airflow from the first air duct 101, thereby directly increasing the flow speed of the airflow from the first air duct 101, and thus enabling the airflow from the first air duct 101 to flow quickly, thereby increasing the flow distance of the airflow from the first air duct 101 and achieving the purpose of extending the air delivery distance.

[0040] It should be understood that in other embodiments of this application, the airflow in the second duct 201 can also be pressurized in other ways. For example, the second fan 220 can be configured as a fan that generates high-pressure, high-speed airflow, thereby enhancing the airflow directed from the first duct 101 without changing the diameter of the second duct 201.

[0041] In some embodiments of this application, in order to gradually reduce the diameter of the second air duct 201, the second housing 210 may be inclined relative to the straight line of the air outlet direction of the first air duct 101, so that the diameter of the second air duct 201 gradually decreases. Since the second air duct 201 is formed by the outer side of the first housing 110 and the inner side of the second housing 210, the inclined arrangement of the second housing 210 can make the distance between the second housing 210 and the first housing 110 gradually decrease along the air outlet direction of the first air duct 101, thus making the diameter of the second air duct 201 gradually decrease.

[0042] It should be noted that, in the embodiments of this application, the second housing 210 is arranged in an inclined state, not only to gradually reduce the diameter of the second air duct 201, but also to guide the airflow exiting the second air duct 201, so that the airflow exiting the second air duct 201 converges with the airflow exiting the first air duct 101. Therefore, the airflow exiting the second air duct 201 can directly act on the airflow exiting the first air duct 101, enhancing its strengthening effect on the first air duct 101.

[0043] Optionally, in order to ensure that the airflow from the second air duct 201 can provide sufficient reinforcement to the airflow from the first air duct 101, and at the same time prevent the airflow from the second air duct 201 from causing turbulence to the airflow from the first air duct 101 and resulting in airflow loss, in some embodiments of this application, the angle of inclination of the second housing 210 relative to the straight line of the air outlet direction of the first air duct 101 is in the range of 0°-15°.

[0044] In cases where the air outlet direction of the second housing 210 relative to the first air duct 101 is too large, the airflow from the second air duct 201 directly inserts into the airflow from the first air duct 101, causing turbulence in the airflow from the first air duct 101. This leads to airflow stall and a sharp drop in airflow distance. Therefore, it is necessary to control the angle of inclination of the second housing 210 relative to the air outlet direction of the first air duct 101 to no more than 15° to ensure effective air outlet.

[0045] It should be noted that the angle of inclination of the second housing 210 relative to the straight line of the air outlet direction of the first air duct 101 refers to the angle formed between the side wall of the second housing 210 and the straight line of the air outlet direction of the first air duct 101, with the straight line of the air outlet direction of the first air duct 101 as a reference. Figure 3 Angle α in. Where, Figure 3The view is a cross-section of the air conditioner 10 along the straight line parallel to the air outlet direction of the first air duct 101. In the figure, of the two dashed lines, the dashed line extending along the second housing 210 represents the extension line of the second housing 210, and the other dashed line represents the straight line along the air outlet direction of the first air duct 101.

[0046] Optionally, the angle of inclination of the second housing 210 relative to the straight line of the air outlet direction of the first air duct 101 can be 0 degrees, 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees or 15 degrees.

[0047] To ensure that the airflow exiting the first air duct 101 can be directly enhanced by the airflow exiting the second air duct 201, optionally, the plane containing the air outlet of the first air duct 101 and the plane containing the air outlet of the second air duct 201 are coplanar. Specifically, after the airflow exits the second air duct 201, it immediately converges with the airflow exiting the first air duct 101, thereby directly enhancing the enhancement effect on the airflow exiting the first air duct 101.

[0048] It should be understood that in other embodiments of this application, the second air duct 201 may also be arranged in other ways. For example, the second housing 210 is slightly protruding in the air outlet direction of the first air duct 101, so that the air outlet of the first air duct 101 is located inside the second air duct 201. In this case, the airflow from the second air duct 201 can be directly injected into the airflow from the first air duct 101, thereby strengthening the airflow from the first air duct 101.

[0049] Optionally, the width of the air outlet of the second air duct 201 is 0.5mm-3mm. In other words, the width of the air outlet of the second air duct 201 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, or 3mm, etc. Setting the width of the air outlet to 0.5mm-3mm not only makes the air outlet of the second air duct 201 narrower so as to raise the airflow from the second air duct 201 to a sufficient air pressure and flow rate, but also ensures that the second air duct 201 has a sufficient air volume to effectively strengthen the airflow from the first air duct 101.

[0050] In some embodiments of this application, in order to prevent the suction effect of the second air duct 201 from affecting the suction of the first air duct 101, thereby ensuring the airflow of the first air duct 101, a volute tongue 112 is formed on the first housing 110, and the volute tongue 112 is located inside the first air duct 101. An air inlet 211 communicating with the second air duct 201 is provided on the second housing 210, and the distance between the air inlet 211 and the volute tongue 112 is greater than 50mm. Because the air intake 111 of the first air duct 101 is close to the volute tongue 112 formed on the first housing 110, when the distance between the volute tongue 112 and the air inlet 211 of the second air duct 201 is greater than 50mm, the distance between the air intake 111 of the first air duct 101 and the air inlet 211 of the second air duct 201 is also greater than 50mm. This ensures that the second air duct 201 will not affect the air intake 111 of the first air duct 101 during the process of intake airflow. This ensures that both the first air duct 101 and the second air duct 201 can intake sufficient airflow, and while ensuring the airflow output by the first air duct 101 is strengthened, the air volume can also be effectively increased.

[0051] Furthermore, since the air inlet 211 of the second air duct 201 is far from the air intake 111 of the first air duct 101, when the air intake 111 of the second air duct 201 draws in airflow, it can avoid affecting the wind field at the air intake 111 of the first air duct 101. This allows the first air duct 101 to effectively draw in airflow through the air intake 111.

[0052] In some embodiments of this application, the second fan 220 is an axial flow fan. Since axial flow fans can generate strong air pressure, it is convenient to form a high-pressure, high-speed airflow in the second air duct 201.

[0053] Additionally, please refer to the following: Figure 2 and Figure 5 In the air conditioner 10 provided in this application, a first housing 110 is connected to a heat exchanger 12, and an air intake 111 communicating with a first air duct 101 is formed on the first housing 110, with the air intake 111 facing the heat exchanger 12. In other words, since the first housing 110 is connected to the heat exchanger 12, the air intake 111 side of the first air duct 101 can substantially enclose the heat exchanger 12, so that the airflow drawn in by the air intake 111 passes through the heat exchanger 12. A first fan 120 is disposed at the air intake 111 to draw in airflow from a designated area. A second fan 220 is disposed between the first housing 110 and the heat exchanger 12 to facilitate the airflow passing through the heat exchanger 12 during the process of the second fan 220 drawing in airflow from the designated area; and an air inlet 211 communicating with a second air duct 201 is formed on the second housing 210, with the air inlet 211 located between the first housing 110 and the heat exchanger 12.

[0054] Since the air inlet 211 is located between the heat exchanger 12 and the first housing 110, it can not only draw in airflow from between the heat exchanger 12 and the first housing 110, ensuring that the airflow drawn in by the air inlet 211 can pass through the heat exchanger 12, but also draw in air from the negative pressure position of the first air duct 101, thereby increasing the overall intake air volume of the air duct structure 11 and improving the overall outlet air volume of the air duct structure 11.

[0055] In summary, when the air duct structure 11 and the air conditioner 10 provided in this embodiment are in the air outlet state, the first fan 120 can export airflow from the main air duct, and the second fan 220 can export airflow from the second air duct 201. The airflow exported from the second air duct 201 flows around the airflow exported from the first air duct 101. Under the strengthening effect of the airflow exported from the second air duct 201, the airflow exported from the first air duct 101 is strengthened, thereby increasing the flow distance of the airflow exported from the first air duct 101, thus extending the air outlet distance and achieving the purpose of a longer blowing distance. When this air duct structure 11 is applied to the air conditioner 10, the technical problem of short air outlet distance in the prior art of the air conditioner 10 can be improved.

[0056] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
