[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, the embodiment of the present application proposes an air guide component, including a casing 1, in which a first cross-flow fan 2 and a second cross-flow fan 3 are relatively arranged, the casing 1 is provided with an air inlet side 19 and an air outlet side 20, the air inlet side 19 is sequentially provided with a first air outlet 7, a second air outlet 8 and a third air outlet 9, the first air outlet 7, the second air outlet 8 and the third air outlet 9 are respectively provided with a first movable air guide member 10, a second movable air guide member 11 and a third movable air guide member 12; the first cross-flow fan 2 and the second cross-flow fan 3 are respectively provided with a first air duct 4 and a third air duct 6 in the direction of the air outlet side 20, the first air duct 4 is connected to the first air outlet 7, and the third air duct 6 is connected to the first air outlet 7. The third air duct 6 is connected to the third air outlet 9; a second air duct 5 corresponding to the second air outlet 8 is independently arranged in the casing 1, and rotating volutes 13 are arranged on both sides of the second air duct 5, and the first clamping position 17 and the second clamping position 18 are respectively arranged on both sides of the rotating volutes 13, and when the two rotating volutes 13 are rotated to the first clamping position 17, the second air duct 5 is in a sealed and wind-proof state; when the two rotating volutes 13 are rotated to the second clamping position 18, the first air duct 4 and the third air duct 6 are both connected to the second air duct 5, and the side of the first air duct 4 close to the first air outlet 7 is closed, and the side of the third air duct 6 close to the third air outlet 9 is closed.

[0022] That is to say, the rotating volute 13 can adjust the air outlet mode by rotating, specifically, Figure 2 , Figure 3As shown, during operation, when the two rotating volutes 13 are rotated to the first locking position 17, the second air duct 5 is in a sealed wind-proof state, that is, the first cross-flow fan 2 and the second cross-flow fan 3 respectively introduce wind into the first air duct 4 and the third air duct 6, and at the same time control the first movable air guide 10 and the third movable air guide 12 to control the opening and closing states of the first air outlet 7 and the third air outlet 9, thereby achieving the effect of air outlet on both sides; and when the two rotating volutes 13 are rotated to the second locking position 18, the first air duct 4 and the third air duct 6 are both connected to the second air duct 5, and the side of the first air duct 4 close to the first air outlet 7 is closed, and the side of the third air duct 6 close to the third air outlet 9 is closed, that is, the wind of the first cross-flow fan 2 and the second cross-flow fan 3 is all concentrated into the second air duct 5, and is concentratedly discharged through the second air outlet 8, which can ensure concentrated air outlet, improve air outlet intensity and blowing distance, and realize the front side strong air outlet working mode.

[0023] When the rotating volute 13 is in the first locking position 17 and is in a closed state, the air duct presents left and right dual air outlet ducts, which can realize the side air outlet function. The rotating function of the rotating volute 13 is utilized to re-divide the fresh air duct, and the airflow in the left and right ducts is guided to the second duct 5 and the second air outlet 8, which can realize the front air outlet function. At the same time, the air volume of the two ducts is guided to the middle duct, which can also increase the front air outlet volume.

[0024] At the same time, the first air duct 4 and the third air duct 6 in the above-mentioned casing 1 are divided and sealed by the volute casing, the above-mentioned first clamping position 17 includes notches on the sides close to the first air duct 4 and the third air duct 6, and the second clamping position 18 includes channels of the first air duct 4 and the third air duct 6 close to the first air outlet 7 side and the third air outlet 9 side respectively, and the size of the rotating volute 13 is the same as the size of the notch and the channel and they are sealed with each other, and the rotating volute 13 is an arc-shaped volute as a whole, which will not interfere with the volute casing during the actual rotation process.

[0025] Specifically, the first movable air guide member 10 and the third movable air guide member 12 both include air guide swing blades, which can be swung through the motor transmission in the prior art to achieve stable and precise control effects, and the two air guide swing blades are shuttle-shaped swing blades that are mirror-symmetrically arranged based on the center line of the casing 1, and the maximum rotation angle of the shuttle-shaped swing blades is 70°. A unified control mechanism can be used to achieve synchronous control of the two air guide swing blades, and the air guiding effect of the arc-shaped air guide side of the shuttle-shaped swing blades is better. The swing blade design of the first air outlet 7 and the third air outlet 9 is based on the Coanda effect, and utilizes the arc surface design of the swing blades to allow the airflow to fit the arc profile to discharge air, thereby enhancing the directionality of the airflow flow.

[0026] In addition, the second movable air guide member 11 includes an arc-shaped air guide plate protruding toward the outside of the casing 1, the arc-shaped air guide plate is provided with a plurality of air guide channels evenly spaced, and an automatic shielding member is provided in the air guide channel, and the air guide channel can be sealed and opened by the automatic shielding member. Specifically, the automatic shielding assembly includes a shielding strip movably provided on the arc-shaped air guide plate, and the shielding strip is provided with a motor transmission system, and the shielding strip is controlled by the motor transmission system to realize the opening and closing of the air guide channel, thereby realizing the sealing and opening of the air guide channel. When the air guide channel in the arc-shaped air guide plate of the second air outlet 8 is close to the center line of the left air outlet channel and can be tilted to the left near the center line of the right air outlet channel, and the air outlet channel gradually shrinks from the inside of the air duct to the outside, the airflow in both air ducts is more concentrated, the air flow velocity is increased, and the front air outlet distance can be increased; when it is close to the center line of the left air outlet channel and can be tilted to the right near the center line of the right air outlet channel, and the air outlet channel gradually expands from the inside of the air duct to the outside, the diffusion angle of the front air outlet airflow is increased. At the same time, the air flow speed is slower when the air is discharged from the front, which breaks up the airflow flow, makes the airflow flow softer, and avoids the occurrence of rapid wind sound.

[0027] The inner diameter of the air guide channel gradually decreases in the direction toward the outside of the casing 1, which can ensure that the airflow is more concentrated, and the airflow intensity and air outlet distance are improved. In addition, the air guide channel can be designed as a perfect circular hole, an elliptical hole or a polygonal hole, which is convenient for processing and has a better ventilation effect.

[0028] Under some specific conditions, the multiple air guide channels on both sides of the above-mentioned arc-shaped air guide plate are inclined toward the side of the center line of the above-mentioned arc-shaped air guide plate in the extension direction toward the outer side of the above-mentioned casing 1, which can achieve the concentration of wind force when the air is discharged from the front. Alternatively, the multiple air guide channels on both sides of the above-mentioned arc-shaped air guide plate are inclined toward the side away from the center line of the above-mentioned arc-shaped air guide plate in the extension direction toward the outer side of the above-mentioned casing 1, so as to achieve a more decentralized air outlet effect.

[0029] This embodiment also proposes a vertical air conditioner indoor unit, including the above-mentioned air guide assembly, and also includes an air inlet frame 14 on the air inlet side 19, a U-shaped evaporator 15 and a heater 16 to ensure that the entire vertical air conditioner indoor unit works normally and stably.

[0030] In summary, the embodiment of the present application proposes an air guide assembly and a vertical air conditioner indoor unit, which adopts a double cross-flow air duct, and designs the volute near the air outlet end into a rotatable air duct profile. When the air conditioner indoor unit is working, by controlling the rotation angle of the rotating volute 13 profile, multiple air outlet modes such as front air outlet and side air outlet are realized, and the vertical air conditioner indoor unit achieves the purpose of multiple wind sensations by rotating the swing blade structure.
