[0020] It should be noted that dual-duct air supply is achieved by means of dual cross-flow fans and the corresponding first and third air ducts 9 and 11, and by providing an adjustable volute 12, it is possible to conveniently adjust the connection or closure between the first and second air ducts 9 and 10, as well as the connection or closure between the third and second air ducts 11 and 10, and through the adjustment action of the first movable air guide member, the second movable air guide member and the third movable air guide member, multiple air outlet modes such as front air outlet, front side air outlet, and side air outlet can be achieved.

[0021] In order to enhance the user's comfort experience and enable the vertical air-conditioning indoor unit to achieve multiple air outlet modes and multiple wind sensations, the present embodiment adopts left and right mirror-image double cross-flow air ducts, that is, the first cross-flow fan 2 and the second cross-flow fan 3, corresponding to the first air duct 9 and the third air duct 11, and the two air ducts are completely separated.

[0022] The air outlet side 4 is divided into three air outlets, namely the first air outlet 6, the second air outlet 7 and the third air outlet 8, wherein the first movable air guide comprises a first arc-shaped swing plate 13 and a second arc-shaped swing plate 14, the arc convex directions of the first arc-shaped swing plate 13 and the second arc-shaped swing plate 14 are opposite, and the first arc-shaped swing plate 13 and the second arc-shaped swing plate 14 cooperate to seal the first air outlet 6; the third movable air guide comprises a third arc-shaped swing plate 15 and a fourth arc-shaped swing plate 16, the arc convex directions of the third arc-shaped swing plate 15 and the fourth arc-shaped swing plate 16 are opposite, and the third arc-shaped swing plate 15 and the fourth arc-shaped swing plate 16 cooperate to seal the third air outlet 8. Through the arc-shaped design of the swing plate, the airflow can be guided in an arc shape when different swinging postures are achieved, which is conducive to airflow convergence and increases the airflow speed.

[0023] The second curved swing plate 14 and the third curved swing plate 15 are located on both sides of the second movable air guide member, and the second curved swing plate 14 and the third curved swing plate 15 protrude into the casing 1, and the first curved swing plate 13 and the fourth curved swing plate 16 protrude outward from the casing 1. The cylindrical air duct formed by the convex and concave swing blades is conducive to making the directionality of the blown airflow more clear.

[0024] The above-mentioned second movable air guide member includes two mirror-arc swing plates 17, and the two above-mentioned arc swing plates 17 are used to seal the above-mentioned second air outlet 7. The two arc-shaped swing plates cooperate to form a closed arc-shaped seal to ensure the airtightness of the second air outlet 7. At the same time, the arc-shaped swing plate structure can enhance the overall appearance aesthetics after cooperation.

[0025] like Figure 2 As shown, when the vertical air-conditioning indoor unit is in the front air outlet mode, the adjustable volutes 12 on both sides of the second air duct 10 are opened, and the rotation angle is 30°-90°, so that the two sides of the second air duct 10 are connected with the first air duct 9 and the third air duct 11 respectively; the two arc-shaped swing blades of the second air outlet 7 rotate clockwise and counterclockwise respectively, and the maximum rotation angle is 50°; the above-mentioned first arc-shaped swing plate 13 and the above-mentioned fourth arc-shaped swing plate 16 rotate toward the outside of the air duct, with a maximum rotation angle of 40°, and the above-mentioned second arc-shaped swing plate 14 and the above-mentioned third arc-shaped swing plate 15 rotate toward the inside of the air duct, with a rotation angle of 0°-30°; at this time, the airflow inhaled by the first cross-flow fan 2 and the second cross-flow fan 3 is introduced toward the air outlet side 4, and the airflow flows in the first air duct 9, the second air duct 10 and the third air duct 11 at the same time and is discharged through the first air outlet 6, the second air outlet 7 and the third air outlet 8, forming an effect of three air outlets discharging air forward.

[0026] like Figure 3As shown, when the vertical air-conditioning indoor unit is in the side-front air outlet mode, the adjustable volutes 12 on both sides of the second air duct 10 are in a closed state, and the two arc swing plates 17 in the second air outlet 7 are in a closed state, so that the second air duct 10 and the second air outlet 7 form a closed state, and air cannot be taken in or out; the first arc swing plate 13 and the fourth arc swing plate 16 in the first air outlet 6 and the third air outlet 8 rotate toward the outside of the air duct, and the rotation angle is 0-40°, and the second arc swing plate 14 and the third arc swing plate 15 rotate toward the inside of the air duct, and the rotation angle is 30°-120°; at this time, the airflow inhaled by the first cross-flow fan 2 and the second cross-flow fan 3 is introduced toward the air outlet side 4, and the airflow flows in the first air duct 9 and the third air duct 11 at the same time and is exported to the first air outlet 6 and the third air outlet 8, forming a side-front air outlet effect.

[0027] like Figure 4 As shown, when the vertical air conditioner indoor unit is in the side air outlet mode, the adjustable volutes 12 on both sides of the second air duct 10 are in a closed state, the two arc swing plates 17 in the second air outlet 7 are in a closed state, and the second arc swing plates 14 and the third arc swing plates 15 in the first air outlet 6 and the third air outlet 8 are first rotated toward the inside of the air duct, and the rotation angle is greater than 120° to avoid interference with the first arc swing plates 13 and the fourth arc swing plates 16 during rotation. When the second arc swing plates 14 and When the rotation angle of the third curved swing plate 15 is greater than 120°, the first curved swing plate 13 and the fourth curved swing plate 16 begin to rotate toward the inside of the air duct, and the rotation angle is 0-60°. At this time, the protruding directions of the first curved swing plate 13, the fourth curved swing plate 16, the second curved swing plate 14 and the third curved swing plate 15 are all toward the second air outlet 7, and the airflow is guided toward the directions of both sides of the air outlet side 4 under the guiding action of the curved swing blades, thereby achieving the side air outlet effect.

[0028] The first air duct 9 and the third air duct 11 are connected to the second air duct 10 so that the air flow is guided to the second air outlet 7. The arc swing plate 17 in the second air outlet 7 rotates toward the outside of the air duct, and the width of the second air outlet becomes narrower, which is conducive to gathering the air flow, increasing the air flow velocity, and blowing farther. The rotation angle of the swing blade design in the first air outlet 6 and the third air outlet 8 is conducive to guiding the side air flow to the front direction of the indoor unit, thereby increasing the front air volume. When the vertical air conditioner indoor unit realizes the front side air outlet function, the air flow is blown out from the air ducts on both sides, and a convex and a concave swing blade form an air outlet duct. The air duct becomes narrower from wide, which is conducive to air flow convergence, increasing air flow velocity, and blowing farther. At the same time, the cylindrical air duct formed by the convex and the concave swing blade is conducive to making the directionality of the blown air flow clearer. When the vertical air conditioner indoor unit realizes the side air outlet function, the air flow is blown out from the air ducts on both sides. At the same time, according to the Coanda effect, the swing blade arc surface design is used to allow the air flow to fit the arc profile and discharge from the side, so that the middle area cannot feel the air flow.

[0029] In addition, the adjustable volute 12 includes at least one rotating plate. The rotating plates on both sides of the second air duct 10 adjust the isolation or connection state of the second air duct 10 by rotating a preset angle, forming a shutter-like sealing and opening mode to ensure sufficient air guide area.

[0030] Moreover, the movable adjustment of the first movable air-guiding member, the second movable air-guiding member, the third movable air-guiding member and the adjustable volute 12 are all existing technologies, specifically, precise adjustment and control are achieved through a servo motor and a transmission structure.

[0031] In addition, the present embodiment also proposes a vertical air-conditioning indoor unit, including the above-mentioned air guide assembly, specifically also including an air inlet frame 18 arranged on the air inlet side 5, a U-shaped evaporator 19 is arranged on one side of the air inlet frame 18, and a heater 20 is correspondingly arranged on the first cross-flow fan 2 and the second cross-flow fan 3 close to the evaporator side, so as to realize the overall air-conditioning applicable configuration and achieve stable performance.

[0032] In summary, the utility model proposes an air guide component and a vertical air-conditioning indoor unit. When the vertical air-conditioning indoor unit realizes the front air outlet function, the opening and closing function of the adjustable volute 12 is utilized to realize that the two air ducts corresponding to the first cross-flow fan 2 and the second cross-flow fan 3 can realize the centralized side air guide and the diversion to the second air duct 10 to realize the adjustment of the front air guide, and the first air guide movable part, the second movable air guide part and the third movable air guide part control the opening and closing of the first air outlet 6, the second air outlet 7 and the third air outlet 8 and control the opening and closing degree, so that the whole can coordinately regulate different air outlet modes to ensure the best experience effect under the adaptation scene.
