[0046] As the indoor part of a split type refrigeration equipment, the air conditioner indoor unit has various air guide plate air outlet structures, such as single air guide plate single motor structure with small air guide plate, double air guide plate double motor structure, and large air guide plate structure with a push-out mechanism. The single air guide plate single motor structure with small air guide plate can achieve ordinary wide-angle air supply from top to bottom, but cannot achieve the human comfort effect of blowing cold air upward and hot air downward. The double air guide plate double motor structure can achieve the human comfort effect of blowing cold air upward and hot air downward, the air guide plate belongs to a similar plane air guide, the air outlet space range is limited, and the air guide plate movement interference and air guide plate shaking caused by airflow turbulence are prone to occur. The large air guide plate structure with a push-out mechanism can achieve the human comfort effect of blowing cold air upward and hot air downward, the large air guide plate needs to be rotated after being pushed out of the air outlet to achieve, the air guide plate has problems of large movement stroke and large running resistance, the driving box design is reliable and has a high cost, and the use of cost reduction design is prone to cause unreliable air guide plate operation.

[0047] To solve the technical problems of airflow turbulence and large noise caused by the air guide plate rotatingly arranged at the air outlet in the prior art, the present application provides an air guide device, an air conditioner indoor unit, an air conditioner, and a control method thereof.

[0048] In combination with the accompanying Figures 1-18 As shown in the drawings, an air guide device is arranged at an air outlet 5, the length direction of the air outlet 5 is a horizontal direction, the upper end of the air guide device is provided with an upper working position 1, and the lower end of the air guide device is provided with a lower working position 2. The air outlet 5 has an upper boundary 501 and a lower boundary 502, the air guide device comprises an air guide platform 6, the length direction of the air guide platform 6 is consistent with the length direction of the air outlet 5, when the air guide platform 6 slides upward to the upper working position 1, the air guide platform 6 is in contact with the upper boundary 501, and a first lower air outlet part 102 is formed between the air guide platform 6 and the lower boundary 502, when the air guide platform 6 slides downward to the lower working position 2, the air guide platform 6 is in contact with the lower boundary 502, and a first upper air outlet part 101 is formed between the air guide platform 6 and the upper boundary 501.

[0049] By setting the air guide device at the air outlet 5, the air guide device comprises a slidable air guide platform 6, the air guide platform 6 slides to the upper working position 1, the airflow flows out from the first lower air outlet part 102, realizing the lower air outlet, the air guide platform 6 slides to the lower working position 2, the airflow flows out from the first upper air outlet part 101, realizing the upper air outlet; on the one hand, the change of the air outlet direction is realized; on the other hand, compared with the prior art which realizes the air outlet in different directions by rotating the air guide plate, the present application realizes the air outlet in different directions by sliding the air guide platform 6, effectively avoiding the airflow turbulence caused by the rotation of the air guide plate, and further reducing the noise volume caused by the turbulence airflow blowing the air guide plate.

[0050] In the present application, the size of the wind speed and the wind volume are both irrelevant to the rotating speed of the fan, and are described when the rotating speed of the fan is constant.

[0051] Preferably, as shown in Figure 1 and Figure 2 The upper working position 1 and the lower working position 2 are provided with a middle working area 3, when the air guide platform 6 slides to the middle working area 3, the air guide platform 6 can slide in the middle working area 3, the upper boundary 501 and the air guide platform 6 form a second upper air outlet part 201, and the lower boundary 502 and the air guide platform 6 form a second lower air outlet part 202.

[0052] The middle working area 3 is not a point value, but a range, specifically, the positions except the upper working position 1 and the lower working position 2 belong to the middle working area 3, and the sliding of the air guide platform 6 in the middle working area 3 can change the air outlet area of the second upper air outlet part 201 and the second lower air outlet part 202. The actual air outlet area of the second upper air outlet part 201 is part of the first upper air outlet part 101, and the actual air outlet area of the second lower air outlet part 202 is part of the first lower air outlet part 102.

[0053] When the air guide platform 6 slides to the middle working area 3, the airflow can flow out from the second upper air outlet part 201 and the second lower air outlet part 202 at the same time; of course, the effective ventilation area of the second upper air outlet part 201 is smaller than that of the first upper air outlet part 101, and the effective ventilation area of the second lower air outlet part 202 is smaller than that of the first lower air outlet part 102. Since the position of the middle working area 3 is adjustable, the distribution of the upper air outlet and the lower air outlet volume is realized by adjusting the position of the air guide platform 6, further meeting the different needs of users.

[0054] Preferably, as shown in Figure 13 and Figure 14 The air guide platform 6 comprises an upper flow guide surface 601 facing the upper boundary 501 and a lower flow guide surface 602 facing the lower boundary 502.

[0055] The upper flow guide surface 601 can guide the gas flowing out of the first upper air outlet part 101, and the upper flow guide surface 601 can guide the gas flowing out of the first lower air outlet part 102; effectively reducing the resistance of the gas flowing through the air guide table 6, which is conducive to improving the flow speed of the gas, and also reducing the impact of the gas on the air guide table 6, which is conducive to reducing noise.

[0056] Preferably, as shown in Figure 14 The upper flow guide surface 601 is a concave arc surface, and / or the lower flow guide surface 602 is a concave arc surface.

[0057] The flow guide surface is a concave arc surface, and the impact of the gas on the air guide table 6 is smaller when the gas flows through the flow guide surface, further reducing the vibration and noise of the air guide table 6; because the flow guide surface is a concave arc surface, the flow guide surface changes the flow direction of the gas more, which can better adjust the flow direction and range of the gas.

[0058] Preferably, as shown in Figure 14 The upper flow guide surface 601 and the lower flow guide surface 602 intersect to form a flow dividing tip 603, and the flow dividing tip 603 faces the wind direction.

[0059] By making the upper flow guide surface 601 and the lower flow guide surface 602 form a flow dividing tip 603, the flow dividing tip 603 faces the wind direction, and when the air guide table 6 slides to the middle working area 3, the airflow is divided, which is conducive to reducing the resistance of the airflow and improving the flow speed and flow rate of the airflow.

[0063] As shown in Figure 6 And Figure 7As shown, the first air deflector 401 sliding out of the first accommodating groove 6011 can reduce the air outlet area of the first upper air outlet part 101 or the second upper air outlet part 201, thereby controlling the air volume and air speed of the air outlet, considering the air resistance and gas leakage, the more the first air deflector 401 slides out of the first accommodating groove 6011, the smaller the effective air outlet area of the first upper air outlet part 101 or the second upper air outlet part 201, the greater the air speed, and the air volume is reduced; it is beneficial to send the airflow farther. Similarly, as shown, Figure 9 and Figure 10 As shown, the second air deflector 402 sliding out of the second accommodating groove 6021 can reduce the air outlet area of the first lower air outlet part 102 or the second lower air outlet part 202, thereby controlling the air volume and air speed of the air outlet, considering the air resistance and gas leakage, the more the second air deflector 402 slides out of the second accommodating groove 6021, the smaller the effective air outlet area of the first lower air outlet part 102 or the second lower air outlet part 202, the greater the air speed, and the air volume is reduced; it is beneficial to send the airflow farther.

[0064] The first air deflector 401 can be hidden in the first accommodating groove 6011, and the second air deflector 402 can be hidden in the second accommodating groove 6021.

[0077] Preferably, when the middle working area 3 is provided, the control method further comprises: when the air conditioner starts the heating mode or the cooling mode, the air guide table 6 slides to the middle working area 3.

[0078] When the air conditioner starts the heating mode or the cooling mode, the air guide table 6 slides to the middle working area 3, so that the hot air or the cold air is blown from the second upper air outlet 201 and the second lower air outlet 202 at the same time, thereby simultaneously adjusting the temperature of different areas in the room, which is beneficial to improve the temperature adjustment efficiency of the room and can also direct the air flow to different people in different areas of the room, thereby improving the user experience. Since the air guide table 6 can slide in the middle working area 3, the air outlet area of the second upper air outlet 201 and the second lower air outlet 202 can be adjusted, and the air outlet amount of the second upper air outlet 201 and the second lower air outlet 202 can be adjusted.

[0079] Preferably, when the first air guide plate 401 and the second air guide plate 402 are provided and the middle working area 3 is provided, the control method further comprises: when the air conditioner starts the heating mode and the air guide table 6 slides to the upper working position 1, the second air guide plate 402 is controlled to slide; when the air conditioner starts the heating mode and slides to the middle working area 3, the first air guide plate 401 and the second air guide plate 402 are controlled to slide; when the air conditioner starts the cooling mode and the air guide table 6 slides to the lower working position 2, the first air guide plate 401 is controlled to slide; when the air conditioner starts the cooling mode and slides to the middle working area 3, the first air guide plate 401 and the second air guide plate 402 are controlled to slide.

[0080] When the air conditioner is in heating mode and the air guide platform 6 is slid to the upper working position 1, the second air guide plate 402 is controlled to slide, and the second air guide plate 402 slides out of the second accommodating groove 6021 to reduce the air outlet area of the first lower air outlet part 102, improve the air outlet speed of the air discharged from the first lower air outlet part 102, and the second air guide plate 402 slides into the second accommodating groove 6021 to increase the air outlet area of the first lower air outlet part 102, and improve the air outlet quantity of the air discharged from the first lower air outlet part 102. When the air conditioner is in heating mode and the middle working area 3 is slid, the first air guide plate 401 and the second air guide plate 402 are controlled to slide, the air outlet area of the second upper air outlet part 201 and the second lower air outlet part 202 can be adjusted, and then the air outlet speed and the air outlet quantity of the second upper air outlet part 201 and the second lower air outlet part 202 are changed. The greater the air outlet speed is, the smaller the air outlet quantity per unit time is considering the air resistance, and similarly, the smaller the air outlet speed is, the greater the air outlet quantity per unit time is due to the reduced air resistance. When the air conditioner is in cooling mode and the air guide platform 6 is slid to the lower working position 2, the first air guide plate 401 is controlled to slide, and the hot air is discharged from the first upper air outlet part 101. The first air guide plate 401 slides out of the first accommodating groove 6011 to reduce the air outlet area of the first upper air outlet part 101, and then the air outlet speed is improved, and the air supply distance is improved. When the first air guide plate 401 slides out of the first accommodating groove 6011, the air guide distance of the air is also prolonged, and the air supply distance is further improved. When the air conditioner is in cooling mode and the middle working area 3 is slid, the first air guide plate 401 and the second air guide plate 402 are controlled to slide, the air outlet area of the second upper air outlet part 201 and the second lower air outlet part 202 can be adjusted, and then the air outlet speed and the air outlet quantity of the second upper air outlet part 201 and the second lower air outlet part 202 are changed. The greater the air outlet speed is, the smaller the air outlet quantity per unit time is considering the air resistance, and similarly, the smaller the air outlet speed is, the greater the air outlet quantity per unit time is due to the reduced air resistance.

[0081] When the air conditioner is turned off, the size of the air outlet 5 is appropriate, and the air guide platform 6 is slid to the middle working area 3, the first air guide plate 401 slides out of the first accommodating groove 6011 and closes the second upper air outlet part 201, the second air guide plate 402 slides out of the second accommodating groove 6021 and closes the second lower air outlet part 202, and then the air outlet 5 is closed.
