Detailed Embodiments

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

[0021] According to Figure 1 As shown, an air guiding assembly is proposed in an embodiment of the present application, which includes a casing 1. A first cross-flow fan 2 and a second cross-flow fan 3 are oppositely arranged inside the casing 1. The casing 1 is provided with an air inlet side 13 and an air outlet side 14. The air outlet side 14 is provided with a first air outlet 4 and a second air outlet 5 corresponding to the first cross-flow fan 2 and the second cross-flow fan 3 respectively. A first swing blade 9 is arranged at the first air outlet 4, and a second swing blade 10 is arranged at the second air outlet 5. First air ducts 7 and second air ducts 8 are respectively arranged in the directions of the first cross-flow fan 2 and the second cross-flow fan 3 facing the air outlet side 14. The first air duct 7 communicates with the first air outlet 4, and the second air duct 8 communicates with the second air outlet 5.

[0022] A third air outlet 6 is arranged between the first air outlet 4 and the second air outlet 5. A rotary air guiding frame 11 is arranged between the first air duct 7 and the second air duct 8. The rotary air guiding frame 11 is in the shape of a regular polygon and is hollow. The rotary air guiding frame 11 is provided with a plurality of air guiding sides. Among them, the air guiding side facing the air outlet side 14 covers the third air outlet 6 and has the same size as the third air outlet 6. The air guiding side facing the first air duct 7 forms a part of the side wall of the first air duct 7, and the air guiding side facing the second air duct 8 forms a part of the side wall of the second air duct 8. The number of defined air guiding sides is n, the sealed side 111 is 1, and the hollowed-out side 112 is n - 1, where n ≥ 3.

[0023] An air inlet frame 15 is arranged at the air inlet side 13. A U-shaped evaporator 16 is arranged on the side of the air inlet frame 15 close to the inner side of the casing 1. The U-shaped evaporator 16 is located on the side of the first cross-flow fan 2 and the second cross-flow fan 3 away from the air outlet side 14 and forms a unilateral surrounding of the first cross-flow fan 2 and the second cross-flow fan 3. A first heater 17 and a second heater 18 are respectively arranged between the U-shaped evaporator 16 and the first cross-flow fan 2 and the second cross-flow fan 3, which is convenient for the air guiding diversity and comfort of the overall air conditioner.

[0024] It should be noted that air is sent to the corresponding first air duct 7 and second air duct 8 through the first cross-flow fan 2 and the second cross-flow fan 3. At the same time, by adjusting the rotation of the rotary air guide frame 11, when the sealing side 111 of the rotary air guide frame 11 rotates towards the inside of the housing 1, the first air duct 7 and the second air duct 8 are communicated. And by coordinating the adjustment of the angles of the first swing blade 9 and the second swing blade 10, the air can pass through the inside of the rotary air guide frame 11 and exit from the third air outlet 6, realizing strong air outlet at the front side, or exiting from the third air outlet 6, the first air outlet 4 and the third air outlet 6 together, increasing the air outlet area. When the sealing side 111 of the rotary air guide frame 11 rotates towards the first air duct 7, the sealing side 111 and the first swing blade 9 seal the first air duct 7, and the first swing blade 9 seals the first air outlet 4, realizing the sealing of the first air duct 7. The air passes through the second air duct 8 into the rotary air guide frame 11 and exits from the third air outlet 6 and / or the second air outlet 5, realizing a weaker air outlet mode on one side. When the sealing side 111 of the rotary air guide frame 11 rotates towards the second air duct 8, the sealing side 111 and the second swing blade 10 seal the second air duct 8, and the air passes through the first air duct 7 into the rotary air guide frame 11 and exits from the third air outlet 6 and / or the first air outlet 4, also realizing a weaker air outlet mode on one side. When the sealing side 111 of the rotary air guide frame 11 rotates towards the outside of the housing 1, the first swing blade 9, the sealing side 111 and the second swing blade 10 close the air outlet side 14, realizing a closed mode. By adjusting the air outlet modes such as strong air outlet at the front side, weak air outlet on one side, and side air outlet, it can be ensured that it is applicable to various practical scenarios and can meet the comfort requirements in various scenarios.

[0025] Moreover, it should be noted that a volute 12 for separating the first air duct 7 and the second air duct 8 is provided inside the housing 1. The part of the volute 12 close to the side of the rotary air guide frame 11 facing the inside of the housing 1 is adapted to the rotary air guide frame 11, does not interfere with the rotation of the rotary air guide frame 11, and is hermetically cooperated with the side of the rotary air guide frame 11 facing the inside of the housing 1. That is to say, when a certain hollow side 112 or sealing side 111 rotates to the side of the rotary air guide frame 11 facing the inside of the housing 1, a certain hollow side 112 or the sealing side 111 forms a part of the volute 12 that blocks the first air duct 7 and the second air duct 8. That is to say, the actual working side of the rotary air guide frame 11 is only the other three air guide sides except the side of the rotary air guide frame 11 facing the inside of the housing 1, and the air guide side rotating to the side facing the inside of the housing 1 does not produce any conduction or sealing effect.

[0026] It should be noted that in one embodiment of the above-mentioned rotary air guide frame 11, the cross-sectional shape is an equilateral triangle, including a sealed side 111 on one plane and hollowed-out sides 112 on two planes. At this time, the rotary air guide frame 11 has three working states, that is, three positions formed by the rotation of the sealed side 111. When the sealed side 111 rotates towards the air outlet side 14, the third air outlet 6 is sealed. When the sealed side 111 rotates towards the first air duct 7 side, the connection between the first air duct 7 and the third air outlet 6 is blocked. When the sealed side 111 rotates towards the second air duct 8 side, the connection between the second air duct 8 and the third air outlet 6 is blocked. In another embodiment, the cross-section of the rotary air guide frame 11 is a square, including a sealed side 111 on one plane and hollowed-out sides 112 on three planes. The working state is similar to that of the equilateral triangle rotary air guide frame 11. The difference is that when the sealed side 111 rotates towards the inside of the casing 1, both the first air duct 7 and the second air duct 8 are connected to the third air outlet 6.

[0027] As Figure 5 shown, the above-mentioned sealed side 111 includes at least one sealing plate, the above-mentioned hollowed-out side 112 includes at least one air guide plate, and a plurality of air guide holes are provided in the air guide plate. The air guide holes can be circular ventilation holes or elliptical ventilation holes to improve the air guide efficiency. The above-mentioned rotary air guide frame 11 is a regular octagon, and the number of air guide sides is four. Among them, one of the above-mentioned sealed sides 111 includes any two adjacent sides of the rotary air guide frame 11, and the other six sides sequentially form three adjacent hollowed-out sides 112.

[0028] The structure and the content of the drawings in this embodiment are all described with respect to the cross-sectional structure of the vertical air conditioner. Specifically, the air guide side facing the above-mentioned first air duct 7 extends outward to the above-mentioned first air outlet 4, and the air guide side facing the above-mentioned second air duct 8 extends outward to the above-mentioned second air outlet 5. The above-mentioned first air outlet 4, the above-mentioned third air outlet 6, and the above-mentioned second air outlet 5 are sequentially connected and form an integral air outlet opening. The above-mentioned first swing blade 9, the air guide side facing the above-mentioned air outlet side 14, and the above-mentioned second swing blade 10 jointly realize the opening and closing of the above-mentioned air outlet opening. That is to say, the above-mentioned rotary air guide frame 11 is directly arranged in the middle of the first air outlet 4 and the second air outlet 5, and notches with dimensions equivalent to those of the air guide side are provided on the side walls of the adjacent sides of the first air duct 7 and the second air duct 8 close to the above-mentioned third air outlet 6 respectively. The air guide side can block the notches. When a single sealed side 111 can rotate to one of the notches, the connection between the first air duct 7 or the second air duct 8 and the third air outlet 6 is blocked, which is convenient for adjusting the air outlet direction and strength.

[0029] It should be noted that the shapes of the above-mentioned first swing blade 9 and the second swing blade 10 are both spindle-shaped, and can also be olive-shaped or crescent-shaped. Moreover, the above-mentioned first swing blade 9 and the second swing blade 10 are both used to rotate to a preset angle to cooperate with the above-mentioned rotary air guide frame 11 to form different air guide modes. That is to say, by adjusting the rotation angles of the retracted first swing blade 9 and the second swing blade 10 respectively, the gaps between them and the air guide side of the third air outlet 6 can be adjusted, so as to realize the adjustment of different air outlet states.

[0030] In actual work, as Figure 1 shown, when the sealing side 111 rotates to the above-mentioned third air outlet 6, and the first air outlet 4 and the second air outlet 5 are respectively sealed by the first swing blade 9 and the second swing blade 10, overall sealing is achieved, avoiding the problem of dust entering in the non-working state; as Figure 2 shown, when the sealing side 111 rotates to the second air duct 8 side, and at the same time the first swing blade 9 and the second swing blade 10 seal the first air outlet and the second air outlet 5, at this time only the first air duct 7 blows air and enters the rotary air guide port from the hollow side 112 on the first air duct 7 side and is simultaneously led out to the hollow side 112 on the third air outlet 6 side. At this time, it is single-sided front air outlet. Similarly, when the sealing side 111 rotates to the first air duct 7 side, and at the same time the first swing blade 9 and the second swing blade 10 seal the first air outlet and the second air outlet 5, at this time only the second air duct 8 blows air and enters the rotary air guide port from the hollow side 112 on the second air duct 8 side and is simultaneously led out to the hollow side 112 on the third air outlet 6 side. This single-sided air guide method has a small and concentrated air volume, can be used in corresponding usage scenarios, and improves comfort.

[0031] As Figure 3 shown, when the sealing side 111 rotates towards the inside of the machine case 1, both the first air duct 7 and the second air duct 8 are communicated with the third air outlet 6. And at this time, the first swing blade 9 and the second swing blade 10 are rotated by a certain inclination angle, and the side of the first swing blade 9 close to the third air outlet 6 is inclined outward, and the side of the second swing blade 10 close to the third air outlet 6 is inclined outward. At this time, the air flows in the first air duct 7 and the second air duct 8 are jointly led out from the first air outlet 4, the second air outlet 5 and the third air outlet 6. And due to the inclined air guiding effect of the first swing blade 9 and the second swing blade 10, most of the air flow is concentrated and led out from the position close to the above-mentioned third air outlet 6. At this time, it is front air outlet, and the wind force is large and the air outlet distance is far, suitable for the application scenario of strong air outlet.

[0032] As Figure 4As shown, no matter which working position the sealing side 111 rotates to, at this time, the first swing blade 9 rotates away from the side of the third air outlet 6 and rotates into the casing 1 until it contacts the volute 12. At this time, the first swing blade 9 and the volute 12 form a sealing effect between the first air duct 7 and the third air outlet 6. The second swing blade 10 and the first swing blade 9 are mirror-symmetrical based on the rotary air guide frame 11, and both the first swing blade 9 and the second swing blade 10 are inclined towards both sides of the air outlet side 14. At this time, the airflows in the first air duct 7 and the second air duct 8 are guided by the first swing blade 9 and the second swing blade 10 to achieve the effect of discharging air from both sides of the first air outlet 4 and the second air outlet 5.

[0033] This embodiment also proposes a vertical air conditioner indoor unit, including the above-mentioned air guide assembly.

[0034] In summary, the embodiment of the present application proposes an air guide assembly and a vertical air conditioner indoor unit. By using the combination of a rotary air guide frame and a multi-air outlet design, the air outlet can be completely closed and the multi-air sense function can be realized. If the ventilation channel of the air guide frame is completely penetrated, it is beneficial to the air flow, reduces noise, and realizes large air volume blowing forward. By using the left and right air guide swing blades as the volute 12 air duct profile, the length of the air duct air outlet can be extended, blocking the path of the air flow to the middle air outlet, completely dividing the air duct, and forming a new side air outlet air duct. According to the Coanda effect of the air flow, by using the arc surface design of the swing blade, the air flow can flow out along the arc profile, thereby enhancing the directivity of the air flow.
