DETAILED DESCRIPTION

[0062] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0063] Combination Figures 1 to 19 According to an embodiment of the present invention, the swirl mechanism 110 includes an air guide tube 111, which has an air flow channel 1101, and the air guide tube 111 has an air inlet 1102, an air suction port 1103 and an air outlet 1104 connected to the air flow channel 1101. The air flow can enter the air guide tube 111 from the air inlet 1102 and the air suction port 1103, flow along the air flow channel 1101 to the air outlet 1104, and be delivered from the air outlet 1104. The air flow channel 1101 extends from the air suction port 1103 to the air outlet 1104, and the air inlet 1102 is constructed to be suitable for tangential air intake along the inner surface of the air guide tube 111, so that the air inlet airflow and the air suction port airflow are mixed in the air flow channel 1101 to form a spiral wind, and are delivered through the air outlet. That is to say, the air flow entering the air guide tube through the air inlet and the air flow entering the air guide tube through the air suction port are mixed in the air flow channel to form a spiral wind and are delivered through the air outlet 1104.

[0064] According to the swirl mechanism 110 of the embodiment of the present invention, the tangential air intake along the inner surface of the air guide tube at the air inlet can form a spiral airflow in the air flow channel, and both the air inlet and the air suction port can supply air into the air flow channel. Through the generated spiral airflow, the airflows from different vents can be mixed and then spirally delivered, thereby improving the mixing effect of the airflows entering from different inlets.

[0065] Among them, the air inlet 1102 can take in air tangentially along the inner circumference of the air guide tube 111. After the air flow enters the air flow channel 1101 from the air inlet 1102, the air flow will form a spiral air supply structure along the inner circumference of the air guide tube 111, and finally be delivered from the air outlet 1104; at the same time, the spiral airflow from the air inlet 1102 to the air outlet 1104 will form a negative pressure on the rear side of the air inlet 1102 (the side where the air suction port 1103 is located). At this time, the air outside the air guide tube 111 will be sucked into the air guide tube 111 through the air suction port 1103. After the air outside the air guide tube 111 is sucked into the air guide tube 111, it can be mixed with the airflow in the air guide tube 111, and finally delivered from the air outlet 1104.

[0066] In the swirl mechanism 110 of the embodiment of the present invention, a spiral airflow can be formed between the air inlet 1102 and the air outlet 1104, and air can also be sucked in from the air suction port 1103, thereby forming a structure in which air is taken in from the air inlet 1102 and the air suction port 1103, and air is discharged from the air outlet 1104. At the same time, the airflow entering the air guide tube 111 through the air inlet 1102 and the airflow sucked into the air guide tube 111 through the air suction port 1103 will be mixed in the air guide tube 111, thereby improving the air outlet effect.

[0067] On the other hand, since the air flow from the air inlet 1102 enters the air guide tube 111, a spiral airflow will be formed. At this time, negative pressure will be formed behind the spiral airflow, which will cause airflow turbulence and reduce the air supply speed of the air outlet 1104. By setting the air suction port 1103, the problem of airflow turbulence can be improved and the wind speed of the air flow when it is delivered from the air outlet 1104 can be increased.

[0068] In the present invention, a fresh air replacement structure can be formed by an airflow driving structure (such as a centrifugal fan module) and a swirl mechanism 110. Specifically, fresh air is introduced from the outside through the airflow driving structure and introduced into the swirl mechanism 110. At the same time, an air inlet 1102 is set at the edge of the swirl mechanism 110, and the airflow flowing into the swirl mechanism 110 is tangentially introduced along the inner wall of the air guide tube 111 to induce a cyclone, so that the airflow forms an annular jet with a certain rotation speed along the inner wall of the swirl mechanism 110, and a negative pressure is generated at the center of the rotating airflow. The rotating airflow inside the swirl mechanism 110 is acted on by the centripetal force on the one hand, and on the other hand, the airflow is The process is also affected by the centrifugal force. Within the balance range of the centripetal force and the centrifugal force, the rotating airflow forms a vortex core, which converges around the negative pressure core and faces the air outlet 1104 of the swirl mechanism 110. At the same time, the air intake 1103 at the rear end of the swirl mechanism 110 is in the negative pressure area, so that a part of the airflow enters through the air intake 1103 at the rear end of the swirl mechanism 110. The air intake 1103 at the rear end of the swirl mechanism 110 can be located on the indoor side, and the indoor and outdoor airflows are fully mixed inside the swirl mechanism 110, so that the outdoor airflow and the indoor airflow form thermal convection, thereby improving the temperature of the outdoor airflow and enhancing the thermal comfort of the fresh air.

[0069] The swirl mechanism 110 is used to achieve uniform mixing of indoor and outdoor airflows, improve the outdoor air temperature, and enhance the thermal comfort of fresh air without introducing a new power source.

[0070] In the present invention, the air guide can be arranged in a variety of different forms to achieve the formation of spiral airflow in the airflow channel 1101. For example:

[0071] A spiral air guide structure (air guide groove, air guide ribs, air guide blades, etc.) is provided in the air guide tube 111 from the air inlet 1102 to the air outlet 1104, and a spiral airflow is formed by the air guide effect of the air guide structure; or

[0072] The air intake port 1103 and the air outlet 1104 of the air guide tube 111 can be set to different sizes, and the flow area of ​​the air intake port 1103 can be set to be smaller than the flow area of ​​the air outlet 1104. In this way, since the wind resistance of the air flow toward the air intake port 1103 is greater than the wind resistance toward the air outlet 1104, the air flow entering the air flow channel 1101 will flow toward the air outlet 1104, and since the air inlet 1102 adopts a tangential air inlet form, a spiral airflow from the air inlet 1102 to the air outlet 1104 will be formed in the air guide tube 111.

[0073] In the above example, there is no restriction on the air inlet direction of the air inlet. For example, the air inlet direction of the air inlet can be an acute angle or a right angle with the air flow direction in the air flow channel (the air flow direction is parallel to the axis of the air guide tube).

[0074] In addition, the present invention also provides other ways to form spiral airflow.

[0075] like Figure 1 As shown, in some embodiments of the present invention, the air inlet direction of the air inlet 1102 is toward the air outlet 1104, and the air inlet 1102 forms a certain angle with the air flow channel; in other words, the angle between the air inlet direction of the air inlet 1102 and the air flow direction in the air flow channel is an acute angle. In this way, the airflow will enter the air guide tube 111 along the tangent direction of the air guide tube 111 at a certain flow rate. Under the constraint of the air guide tube 111, a spiral airflow from the air inlet 1102 to the air outlet 1104 will be formed. Since the airflow has a component speed from the air inlet 1102 to the air outlet 1104 when entering the air guide tube 111, the airflow can be sent to the air outlet 1104 at a greater speed and sent out from the air outlet 1104, and a greater suction force can also be generated at the air inlet 1103.

[0076] Optionally, the angle between the air inlet direction of the air inlet 1102 and the air flow channel may be in the range of 30° to 85°.

[0077] In addition, in order to form a spiral airflow from the air inlet 1102 to the air outlet 1104, the airflow needs to be supplied along the tangential direction in the air guide tube 111. Therefore, the air inlet 1102 can be set at the end of the air guide tube 111, or the air inlet 1102 can be set on the peripheral wall of the air guide tube 111. For example, when the air inlet 1102 is set at the end of the air guide tube 111, the air inlet 1102 can be set so that the angle between the air inlet direction and the airflow direction of the airflow channel is an acute angle (for example, in the range of 30° to 85°), and is tangent to the inner peripheral surface of the air guide tube. In this way, after the airflow enters the air guide tube 111 from the air inlet 1102, an airflow rotating along the circumference of the air guide tube 111 and tilting toward the air outlet 1104 will be formed, thereby forming a spiral air supply.

[0078] In addition, the air inlet 1102 is arranged on the peripheral wall of the air guide tube 111, and a spiral airflow from the air inlet 1102 to the air outlet 1104 can also be formed. For example, the air suction port 1103 and the air outlet 1104 are arranged at opposite ends of the air guide tube 111, and the air inlet 1102 is arranged on the peripheral wall between the two ends of the air guide tube 111. In this way, the air flow can be sent into the air guide tube 111 along the peripheral wall of the air guide tube 111. In combination with the above-mentioned embodiment, a relatively stable spiral airflow can also be formed. Moreover, the air inlet 1102, the air suction port 1103 and the air outlet 1104 are arranged at different positions on the air guide tube 111, which can simplify the structure of the air guide tube 111, avoid interference between different air ports, improve the stability of the air flow process, and reduce turbulence.

[0079] Alternatively, if Figure 2 , the air guide 111 is in a cylindrical shape, and the corresponding central angle α in the cross section where the air inlet 1102 is located is less than 90°, wherein the cross section is a cross section perpendicular to the axis of the air guide. Specifically, the air guide 111 is cut with a plane perpendicular to the axis of the air guide, and in the cross section, the angle between the end points at both ends of the air inlet and the line connecting the axis of the air guide is less than 90°. In other words, with a connection point between the air inlet 1102 and the peripheral wall of the air guide 111 as a reference, the height of the connection port between the air inlet 1102 and the air guide 111 is not greater than half of the height inside the air guide 111, thereby forming a stable spiral airflow, ensuring that air is supplied from the air inlet 1102 to the inside of the air guide 111 along the tangent direction inside the air guide 111, thereby improving the effect of spiral air supply.

[0080] like Figure 1 As shown, the air suction port 1103 may be connected to an air suction pipe, which may be a tubular shape extending along the axial direction of the air guide tube 111; in addition, the air suction pipe may also be a tubular shape extending along an arc direction, and the inlet and outlet of the air suction pipe may have a certain angle, for example, referring to Fig.10The inlet and outlet of the air suction pipe have an angle of 90°. The inlet of the air suction pipe can be set to a trumpet shape, and the size gradually decreases in the air inlet direction.

[0081] Alternatively, if Figure 5 , the air inlet 1102 is located at the center, close to the air suction port 1103. In other words, the air inlet is close to the air suction port 1103 relative to the center position of the air guide tube along the axial direction. In other words, the distance between the air inlet 1102 and the air outlet 1103 is greater than the distance between the air inlet 1102 and the air suction port 1103. Therefore, after the airflow enters the air guide tube 111 from the air inlet 1102, the air guide tube 111 will provide a longer distance of diversion for the airflow, thereby improving the spiral stability of the airflow in the air guide tube 111. Moreover, by arranging the air inlet 1102 at a position close to the air suction port 1103, the suction force of the spiral airflow on the airflow at the air suction port 1103 can be increased, thereby increasing the air volume of the airflow inhaled from the air suction port 1103. Improve the mixing effect of the airflow inhaled by the air suction port 1103 and the airflow entering the air inlet 1102. In addition, the distance between the air inlet 1103 and the spiral airflow formed in the air guide tube 111 is relatively small, which avoids the turbulence problem caused by the excessive space behind the spiral airflow and improves the stability of the airflow.

[0082] Alternatively, if Figure 2 The air inlet 1102 is a channel structure, the opening size of which gradually decreases from the outside to the inside, and the channel structure is tangent to the connection between the outer surface of the air guide tube; wherein, the outside is the direction away from the air guide tube, and the inside is the direction close to the air guide tube. In other words, the opening size of the air inlet gradually decreases in the air inlet direction. Thus, the airflow can enter the air guide tube 111 from the air inlet 1102 along the tangent direction of the air guide tube 111, improve the stability of the airflow, and increase the air intake volume and air intake speed of the air inlet 1102, thereby increasing the air outlet volume and air outlet speed of the air outlet 1104.

[0083] Optionally, the flow area of ​​the air inlet 1103 is smaller than the flow area of ​​the air outlet 1104. This can effectively improve the spiral effect of the airflow in the air guide tube 111, so that the airflow entering the airflow channel 1101 from the air inlet 1102 can flow toward the air outlet 1104 instead of toward the air inlet 1103, which can effectively improve the wind guiding effect. In addition, the small flow area of ​​the air inlet 1103 can also ensure the ratio of the airflow entering the air inlet 1102 to the airflow inhaled by the air inlet 1103, effectively improving the stability and effect of air supply.

[0084] Optionally, the air guide tube 111 includes a hollow cylinder and an end plate, the hollow cylinder is in the shape of a circular tube, and both ends of the hollow cylinder are open, the end plate is connected to the hollow cylinder, and the end plate closes one end of the hollow cylinder. The hollow cylinder and the end plate can be formed separately and then connected together; the hollow cylinder and the end plate can also be arranged in an integrally formed form. An air suction port 1103 is arranged at the center of the end plate 112, and an air outlet 1104 is formed at the other end of the air guide tube 111. During use, a vortex will be formed at the center of the spiral airflow from the air inlet 1102 to the air outlet 1104. Therefore, the suction force at the center of the spiral airflow is greater. By arranging the air suction port 1103 at the center of one end of the air guide tube 111, the air suction effect of the spiral airflow can be effectively improved.

[0085] like Fig.13 As shown, in some embodiments, the air outlet 1104 is configured as a shrinking structure that gradually shrinks inward along the air outlet direction of the air outlet 1104. When the airflow is sent to the air outlet 1104, the shrinking structure at the air outlet 1104 will effectively increase the air outlet speed of the airflow, thereby increasing the air delivery distance of the airflow.

[0086] Optionally, the ratio of the minimum inner diameter d3 to the maximum inner diameter D3 of the constriction structure is in the range of 0.8 to 0.9. For example, the ratio of the minimum inner diameter d3 to the maximum inner diameter D3 of the constriction structure can be set to 0.8, 0.82, 0.85, 0.87, 0.9, etc. Thus, the air flow stability can be ensured while the air outlet speed and air supply distance are effectively improved, and turbulence of the air flow delivered from the air outlet 1104 can be avoided. At the same time, the wind speed of the air outlet 1104 can be improved and the air volume loss can be minimized.

[0087] Of course, according to actual needs and conditions, d3 / D3 may also be set to be less than 0.8 or greater than 0.9, for example, d3 / D3 may be set to be 0.65, 0.75, 0.95, etc.

[0088] In addition, in order to further improve the air supply effect of the air guide 111 and extend the air supply distance of the air outlet 1104, a plurality of shrinking rings can be arranged in the air outlet 1104 of the air guide 111. The plurality of shrinking rings are arranged concentrically and at intervals in a predetermined direction. The shrinking rings are in a shrinking shape that gradually shrinks inward in the air outlet direction of the air outlet 1104. The predetermined direction is the direction from the center of the air outlet 1104 to the inner circumference. In this way, the air outlet effect of the air guide 111 can be further improved, so that the air guide 111 can send airflow to a farther place. When the air guide 111 is used in air conditioning equipment, the air conditioning efficiency can be effectively improved.

[0089] In addition, when a shrinking ring is provided in the air outlet 1104, the inner circumference of the air outlet 1104 may also be provided in a shrinking form (combined with the above description). Of course, the inner circumference of the air outlet 1104 may not be provided in a shrinking form.

[0090] In some embodiments, the length of the inner shrinking ring among the plurality of shrinking rings is smaller than the length of the outer shrinking ring. In other words, in two shrinking rings adjacent to each other along a predetermined direction, the length of the inner shrinking ring is smaller than the length of the outer shrinking ring. This can improve the airflow guiding effect.

[0091] In addition, the ratio of the minimum inner diameter to the maximum inner diameter of the inner shrinking ring among the plurality of shrinking rings is smaller than the ratio of the minimum inner diameter to the maximum inner diameter of the outer shrinking ring. In other words, in two adjacent shrinking rings along a predetermined direction, the ratio of the minimum inner diameter to the maximum inner diameter of the inner shrinking ring is smaller than the length of the outer shrinking ring. This can improve the airflow guiding effect, increase the wind speed of the air outlet 1104 and minimize the air volume loss.

[0092] Optionally, outer end edges of the plurality of shrink rings are flush with the outer end edges of the air outlet 1104 .

[0093] In a specific embodiment of the present invention, a first shrinking ring 113 and a second shrinking ring 114 are arranged in a predetermined direction in the air outlet 1104, and the length s1 of the first shrinking ring 113 is less than the length s2 of the second shrinking ring 114. The length of the shrinking ring refers to the size of the shrinking ring along the axis of the air guide tube 111, for example, the length of the first shrinking ring 113 is the size of the first shrinking ring 113 along the axis of the air guide tube 111; the length of the second shrinking ring 114 is the size of the second shrinking ring 114 along the axis of the air guide tube 111.
