[0039] Reference below Figure 1-Figure 11 An air conditioner indoor unit 100 according to an embodiment of the present invention is described.

[0040] Reference Figure 1 , Figure 2 and Figure 3 According to an embodiment of the present invention, the air conditioner indoor unit 100 comprises: a housing 1, a first air outlet duct 11 and a second air outlet duct 12 are arranged in the housing 1, the inlet end of the first air outlet duct 11 is connected with the second air outlet duct 12, the first air outlet duct 11 has a first air outlet 13, the second air outlet duct 12 has a second air outlet 14, and the first air outlet 13 is located above the second air outlet 14. That is to say, the air conditioner indoor unit 100 in the embodiment of the present invention has at least two air outlets, and the two air outlets are spaced apart in the vertical direction. When the air conditioner is discharged, the wind in the second air outlet duct 12 can flow to the first air outlet duct 11, so that the first air outlet 13 can assist the air conditioner to discharge air, effectively increasing the air outlet area of ​​the air conditioner indoor unit 100, increasing the air outlet volume of the air conditioner indoor unit 100, and improving the air conditioning effect of the air conditioner indoor unit 100.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The air conditioner indoor unit 100 further includes an air guide assembly 2, which is rotatably disposed on the housing 1, and is used to open or close the second air outlet 14. The air guide assembly 2 includes a first air guide plate 21 and a second air guide plate 22 that are relatively rotatable, and the air guide assembly 2 has a separated state and a closed state. In the separated state, the first air guide plate 21 and the second air guide plate 22 are spaced apart to define a ventilation channel, and in the closed state, the first air guide plate 21 and the second air guide plate 22 cooperate to shield the second air outlet 14.

[0042] When the air guide assembly 2 is in the separated state, the two opposite sides of the ventilation channel are respectively connected to the second air outlet duct 12 and the indoor environment. Under the guidance of the ventilation channel, the air outlet direction of the second air outlet 14 is the direction in which the ventilation channel extends from the second air outlet duct 12 to the indoor side. When the air outlet direction of the second air outlet 14 needs to be adjusted, the air guide assembly 2 is driven to rotate relative to the housing 1 to adjust the relative position of the ventilation channel and the second air outlet 14, thereby obtaining different air outlet directions.

[0043] According to the embodiment of the present invention, the air-conditioning indoor unit 100 is provided with two air outlets, and the first air outlet 13 and the second air outlet 14 can discharge air at the same time, which effectively increases the air outlet area of ​​the air-conditioning indoor unit 100, increases the air outlet volume of the air-conditioning indoor unit 100, and improves the air conditioning effect of the air-conditioning indoor unit 100. The first air guide plate 21 and the second air guide plate 22 of the air guide assembly 2 can cooperate with each other to form a ventilation channel that can better guide the air at the second air outlet 14, so as to improve the effect of adjusting the air outlet direction of the air-conditioning indoor unit 100.

[0044] Reference Figure 1 , Figure 2 and Figure 3 In some specific embodiments, the second air outlet duct 12 extends from the top of the housing 1 to the bottom of the housing 1 facing forward, an air inlet 121 communicating with the second air outlet duct 12 is provided at the top of the housing 1, and a second air outlet 14 is provided at the bottom of the housing 1 facing forward. A heat exchanger 3 and a wind wheel 4 are provided in the second air outlet duct 12, and the wind wheel 4 is used to induce airflow from the air inlet 121 to enter the second air outlet duct 12 to exchange heat with the heat exchanger 3 and deliver air to the indoor side.

[0045] Reference Figure 2 , Figure 3 and Figure 8 In some embodiments, the air guide assembly 2 is configured to avoid or shield the inlet end of the first air outlet duct 11 .

[0046] Because the air guide assembly 2 is rotatably disposed on the housing 1, the air guide assembly 2 can be rotated to avoid the inlet end of the first air outlet duct 11, so that the wind in the second air outlet duct 12 can flow into the first air outlet duct 11 and be discharged from the first air outlet 13, thereby increasing the air outlet area of ​​the air conditioner indoor unit 100 and increasing the air outlet volume of the air conditioner indoor unit 100. The air guide assembly 2 can also be rotated to block the inlet end of the first air outlet duct 11 to limit the wind in the second air outlet duct 12 from flowing into the first air outlet duct 11, so that the indoor unit only discharges air from the second air outlet 14.

[0047] Because the air guide assembly 2 includes a first air guide plate 21 and a second air guide plate 22, and the first air guide plate 21 and the second air guide plate 22 can be rotatably disposed on the casing 1, therefore, in some embodiments, the first air guide plate 21 can be rotated to block or avoid the inlet end of the first air outlet duct 11; in other embodiments, the second air guide plate 22 can be rotated to block or avoid the inlet end of the first air outlet duct 11; in yet other embodiments, the first air guide plate 21 and the second air guide plate 22 can be rotated to cooperate with each other to block or avoid the inlet end of the first air outlet duct 11.

[0048] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the first air outlet 13 is located at the top of the front surface of the housing 1 .

[0049] Through the above technical solution, when the air conditioner is blowing out, part of the air conditioner can be discharged from the top of the front surface of the housing 1 through the first air outlet 13, reducing the possibility of the first air outlet 13 blowing directly toward the human body, thereby improving the user experience. In addition, by arranging the first air outlet 13 above the second air outlet 14 and away from the second air outlet 14, not only the air volume of the air conditioner indoor unit 100 is increased, but also the air supply range of the air conditioner indoor unit 100 can be increased, thereby improving the temperature adjustment effect of the air conditioner indoor unit 100 on the indoor environment.

[0050] Reference Figure 1 , Figure 2 and Figure 3 In some specific embodiments, the housing 1 includes a face frame 15 and a front panel 16, the front panel 16 is arranged at the front side of the face frame 15, and the front panel 16 is spaced apart from the face frame 15 to define a first air outlet duct 11. The first air outlet 13 is formed at the top of the front panel 16, the second air outlet 14 is defined between the lower edge of the front panel 16 and the front edge of the bottom wall of the housing 1, and the inlet end of the first air outlet duct 11 is defined between the lower edge of the front panel 16 and the bottom of the face frame 15. That is to say, the second air outlet 14 is spaced apart from the inlet end of the first air outlet duct 11 by the front panel 16, so that the air guide assembly 2 can rotate to block the second air outlet 14 or rotate to guide the second air outlet 14 to discharge air, and the air guide assembly 2 can also rotate to avoid or block the inlet end of the first air outlet duct 11.

[0051] It should be noted that the front panel 16 and the face frame 15 are spaced apart, and the front panel 16 may be connected to the face frame 15 through a bracket, so that the first air outlet duct 11 is defined between the front panel 16 and the face frame 15; or the front panel 16 may be arranged on the front side of the face frame 15 through magnetic suspension, so as to define the first air outlet duct 11. In some specific embodiments, both ends of the front panel 16 in the length direction are connected to the housing 1 through brackets, so that the first air outlet duct 11 is defined between the front panel 16 and the face frame 15.

[0052] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the first air guide plate 21 is configured to be rotatable above or below the second air guide plate 22. That is, the first air guide plate 21 can be rotated to intersect with the second air guide plate 22, that is, the first air guide plate 21 will not interfere with the second air guide plate 22 when rotating, so that the first air guide plate 21 can be rotated to the top of the second air guide plate 22 or to the bottom of the second air guide plate 22, and the rotation of the first air guide plate 21 and the second air guide plate 22 will not interfere with each other, thereby improving the flexibility of the rotation of the first air guide plate 21 and the second air guide plate 22.

[0053] Reference Figure 2 , Figure 3and Figure 4 In some specific embodiments, the first air guide plate 21 and the second air guide plate 22 rotate around the same rotation axis, and the minimum distance between the first air guide plate 21 and its rotation axis is greater than the maximum distance between the second air guide plate 22 and its rotation axis, so that the first air guide plate 21 will not interfere with the second air guide plate 22. When the air conditioner indoor unit 100 is in the off state, the first air guide plate 21 is located in front of the second air guide plate 22, so that the first air guide plate 21 overlaps with the upper edge of the second air outlet 14, shielding the gap between the first air guide plate 21 and the upper edge of the second air outlet 14, thereby improving the aesthetics of the air conditioner indoor unit 100.

[0054] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, the first air guide plate 21 is provided with a first end plate 211 and a second end plate 212 at both ends in the length direction, the first end plate 211 is connected to the first drive shaft 213, and the second end plate 212 is provided with a first avoidance hole 214; the second air guide plate 22 is provided with a third end plate 221 and a fourth end plate 222 at both ends in the length direction, the third end plate 221 is provided with a second avoidance hole 224, and the fourth end plate 222 is provided with a second drive shaft 223.

[0055] Reference Figure 4 , Figure 5 and Figure 6 In the length direction of the air guide assembly 2, the first end plate 211 and the third end plate 221 are located on the same side, and the second end plate 212 and the fourth end plate 222 are located on the same side. The first drive shaft 213 on the first end plate 211 is inserted through the second avoidance hole 224 on the third end plate 221, and the second drive shaft 223 on the fourth end plate 222 is inserted through the first avoidance hole 214 on the second end plate 212.

[0056] The air conditioning indoor unit 100 further includes a driving module, which is adapted to drive the first driving shaft 213 and the second driving shaft 223 to rotate respectively.

[0057] Through the above technical solution, the driving module can drive the first driving shaft 213 and the second driving shaft 223 to rotate respectively, so that the first air guide plate 21 and the second air guide plate 22 can rotate independently without interfering with each other, further improving the rotation flexibility of the first air guide plate 21 and the second air guide plate 22.

[0058] Reference Figure 4 , Figure 5 and Figure 6In some specific embodiments, a first flat opening 217 is provided on the first end plate 211, and the first flat opening 217 can be a non-circular hole such as a rectangular hole, a pentagonal hole, a hexagonal hole, etc., and at least a partial cross-section of the first drive shaft 213 is adapted to the first flat opening 217 so that the first drive shaft 213 can drive the first air guide plate 21 to rotate; a second flat opening 226 is provided on the fourth end plate 222, and the second flat opening 226 can be a non-circular hole such as a rectangular hole, a pentagonal hole, a hexagonal hole, etc., and at least a partial cross-section of the second drive shaft 223 is adapted to the second flat opening 226 so that the second drive shaft 223 can drive the second air guide plate 22 to rotate.

[0059] In some specific embodiments, the driving module includes a first motor and a second motor arranged on both sides of the length direction of the air-conditioning indoor unit 100, the first motor is connected to the first drive shaft 213 for driving the first air guide plate 21 to rotate, and the second motor is connected to the second drive shaft 223 for driving the second air guide plate 22 to rotate.

[0060] In some other embodiments, the first guide groove and the second guide groove may be respectively provided at both ends of the length direction of the casing 1, and the first guide groove and the second guide groove are both annular grooves. The end of the first air guide plate 21 facing the first guide groove is an arc structure, and the first air guide plate 21 is slidably arranged in the first guide groove through the arc structure, so that the first air guide plate 21 rotates around its rotation axis when sliding in the first guide groove; the end of the second air guide plate 22 facing the second guide groove is an arc structure, and the second air guide plate 22 is slidably arranged in the second guide groove through the arc structure, so that the second air guide plate 22 rotates around its rotation axis when sliding in the second guide groove.

[0061] The first air guide plate 21 is also provided with a first rack at one end facing the first guide groove, and the air conditioner indoor unit 100 further includes a first motor, a first gear is provided on the first motor, the first gear and the first rack are meshed with each other, and the first motor is suitable for driving the first air guide plate 21 to rotate through the first gear and the first rack. The second air guide plate 22 is also provided with a second rack at one end facing the second guide groove, and the air conditioner indoor unit 100 further includes a second motor, a second gear is provided on the second motor, the second gear and the second rack are meshed with each other, and the second motor is suitable for driving the second air guide plate 22 to rotate through the second gear and the second rack.

[0062] It should be understood that other situations are also possible, as long as the first air guide plate 21 and the second air guide plate 22 can rotate independently.

[0063] Reference Figure 2 , Figure 7 and Figure 8In some embodiments, the first surface 215 of the first air guide plate 21 facing the rotation axis thereof is formed as a curved surface; the second surface 225 of the second air guide plate 22 facing the rotation axis thereof is formed as a curved surface.

[0064] Through the above technical solution, when the air guide assembly 2 is in a separated state, the first air guide plate 21 and the second air guide plate 22 are separated from each other, and a ventilation channel for guiding the outgoing air is formed between the first surface 215 and the second surface 225. In the embodiment of the present invention, the first surface 215 and the second surface 225 are both curved surfaces, which is conducive to guiding the outgoing air through the ventilation channel, reducing the wind energy loss at the second air outlet 14, so that the wind from the second air outlet 14 can blow farther, and improves the temperature adjustment effect of the air conditioner indoor unit 100 on the indoor environment. In some specific embodiments, the first surface 215 is a curved surface that is concave toward the rotation axis of the first air guide plate 21.

[0065] Reference Figure 2 , Figure 7 and Figure 8 In some embodiments, when the air guide assembly 2 is in a closed state, the adjacent sides of the first air guide plate 21 and the second air guide plate 22 abut against each other to cover the second air outlet 14. When the air conditioner indoor unit 100 is shut down, the air guide assembly 2 can be driven to move to a closed state so that the adjacent sides of the first air guide plate 21 and the second air guide plate 22 abut against each other to cover the second air outlet 14. In this way, dust, rodents or insects can be prevented from entering the second air outlet duct 12 when the air conditioner indoor unit 100 is idle, so as to ensure the working performance of the air conditioner indoor unit 100. Without loss of generality, when the air guide assembly 2 is in a closed state, the first air guide plate 21 and the second air guide plate 22 are accommodated in the second air outlet 14 and are not exposed to the outside. In this way, the outer arc surfaces of the first air guide plate 21 and the second air guide plate 22 can be exposed, and the outer arc surfaces of the two air guide plates have a smooth transition, so that the appearance of the air conditioner indoor unit 100 is highly aesthetic when it is shut down.

[0066] Reference Figure 7 In some embodiments, when the air guide assembly 2 is in a closed state, the mating ends of the first air guide plate 21 and the second air guide plate 22 are staggered in the front-to-back direction to block the gap between the first air guide plate 21 and the second air guide plate 22, which is beneficial to improving the appearance of the air conditioner indoor unit 100 when it is turned off.

[0067] Of course, in other embodiments, the second air outlet 14 may be covered by another cover plate. When the air-conditioning indoor unit 100 is started, the cover plate can move to avoid the second air outlet 14. When the air-conditioning indoor unit 100 is shut down, the cover plate can move to block the second air outlet 14 and the air guide assembly 2.

[0068] Reference Figure 8In some embodiments, the air conditioner indoor unit 100 includes a cooling air outlet mode. In the cooling air outlet mode, the air guide assembly 2 is in a separated state, the first air guide plate 21 is located in the second air outlet duct 12 and blocks the inlet end of the first air outlet duct 11, and the second air guide plate 22 is located in the second air outlet 14 and protrudes from the lower edge of the second air outlet 14. The second air guide plate 22 protrudes from the lower edge of the second air outlet 14 to form a lower air outlet extension section, so that the second air guide plate 22 can guide the air conditioning outlet at the second air outlet 14 to be sent upward and forward, thereby improving the air conditioning effect of the air conditioner indoor unit 100 during cooling. In addition, the second air guide plate 22 can also rotate to form a swept wind, further improving the air conditioning effect of the air conditioner indoor unit 100.

[0069] Reference Fig. 9 In some embodiments, the air-conditioning indoor unit 100 includes a heating air outlet mode. In the heating air outlet mode, the air guide assembly 2 is in a separated state, a portion of the first air guide plate 21 is located in the second air outlet duct 12 and blocks the inlet end of the first air outlet duct 11, and another portion of the first air guide plate 21 protrudes from the upper edge of the second air outlet 14. The first air guide plate 21 protrudes from the upper edge of the second air outlet 14 to form an upper air outlet extension section, so that the first air guide plate 21 can guide the air-conditioned air outlet at the second air outlet 14 to be delivered downward, that is, the first air guide plate 21 can press the hot air downward, thereby improving the air conditioning effect of the air-conditioning indoor unit 100 during heating.

[0070] The second air guide plate 22 is located at the second air outlet 14 and protrudes from the lower edge of the second air outlet 14. The second air guide plate 22 protrudes from the lower edge of the second air outlet 14 to form an extended section of the lower air outlet, so that the second air guide plate 22 can cooperate with the first air guide plate 21 to send air downward. In addition, both the first air guide plate 21 and the second air guide plate 22 can rotate to form a wide range of wind sweeping, further improving the air conditioning effect of the air conditioner indoor unit 100.

[0071] Reference Fig.10 In some embodiments, the air conditioner indoor unit 100 includes a multi-wind mode. In the multi-wind mode, the air guide assembly 2 is in a separated state, the first air guide plate 21 is located in the second air outlet duct 12 and avoids the inlet end of the first air outlet duct 11, and the second air guide plate 22 is located at the second air outlet 14 and is spaced apart from the upper and lower sides of the second air outlet 14.

[0072] Through the above technical solution, when the air conditioner indoor unit 100 is in the multi-wind mode, the air in the second air outlet duct 12 is divided into at least three streams, the first stream of air flows to the first air outlet duct 11 and is discharged from the first air outlet 13, the second stream of air flows to the second air outlet 14 and is discharged in the gap between the second air guide plate 22 and the upper edge of the second air outlet 14, and the third stream of air flows to the second air outlet 14 and is discharged in the gap between the second air guide plate 22 and the lower edge of the second air outlet 14. Compared with the traditional air outlet mode in the related art, the multi-wind mode proposed in the embodiment of the present invention increases the air outlet volume and air outlet range of the air conditioner through the first air outlet 13, and partially blocks the second air outlet 14 through the second air guide plate 22, and guides the air outlet at the second air outlet 14 to the upper and lower sides of the second air guide plate 22, so as to avoid a large amount of air outlet from blowing directly on the user, thereby improving the user experience.

[0073] In some further embodiments, the second air guide plate 22 is provided with a first air guide surface 227 and a second air guide surface 228 on one side of its rotation axis. When the air-conditioning indoor unit 100 is in a multi-wind mode, the first air guide surface 227 is used to guide at least part of the air-conditioning outlet air forward and upward, and the second air guide surface 228 is used to guide at least part of the air-conditioning outlet air backward and downward, thereby further increasing the air supply range of the air-conditioning indoor unit 100 and improving the temperature control effect of the air-conditioning indoor unit 100 on the indoor environment.

[0074] Reference Fig.11 In some embodiments, at least one of the first wind guide plate 21 and the second wind guide plate 22 is provided with a first wind dispersing area 216, and the first wind dispersing area 216 is configured to disperse the airflow. It should be noted that the purpose of the first wind dispersing area 216 is to disperse the air to achieve the purpose of windless feeling. The first wind dispersing area 216 can be a plurality of wind dispersing holes arranged on the wind guide plate, or a plurality of wind dispersing openings arranged on the wind guide plate, or the first wind dispersing area 216 can be provided with a plurality of rotatable dispersing parts to disperse the air, as long as the first wind dispersing area 216 can disperse the air flowing through it.

[0075] The air-conditioning indoor unit 100 also includes a windless mode. In the windless mode, the first air guide plate 21 and the second air guide plate 22 cooperate to block the second air outlet 14. Part of the air-conditioned air is discharged through the first air outlet 13. Because the first air outlet 13 is arranged at the top of the front panel 16, it will not blow directly on the human body. Another part of the air-conditioned air is discharged through the first wind dispersion area 216. Because the first wind dispersion area 216 can disperse the airflow, avoid the air-conditioned air from blowing directly on the human body. The windless mode provided in the embodiment of the present invention can not only improve the user experience, but also ensure the air outlet of the air-conditioning indoor unit 100 through the first air outlet 13, and ensure the temperature adjustment effect of the air-conditioning indoor unit 100 on the indoor environment.

[0076] In some further embodiments, the first air outlet duct 11 is provided with a second wind dispersing area 161 correspondingly, and the second wind dispersing area 161 is configured to disperse the airflow. It should be noted that the purpose of the second wind dispersing area 161 is to disperse the air to achieve the purpose of windless feeling, and the second wind dispersing area 161 can be a plurality of wind dispersing holes provided on the front panel 16, or a plurality of wind dispersing openings provided on the front panel 16, or the second wind dispersing area 161 can be provided with a plurality of rotatable dispersing parts to disperse the air, as long as the second wind dispersing area 161 can disperse the air flowing through it.

[0077] Through the above technical solution, in the windless mode, the air-conditioning outlet is divided into three parts, the first part of the air-conditioning outlet is discharged through the first air outlet 13, the second part of the air-conditioning outlet is discharged through the first wind dispersion area 216, and the third part of the air-conditioning outlet is discharged through the second wind dispersion area 161. The air volume of the air-conditioning indoor unit 100 in the windless mode is effectively increased, and the temperature adjustment effect of the air-conditioning indoor unit 100 on the indoor environment is improved.

[0078] In some specific embodiments, the first air guide plate 21 is provided with a plurality of first air dispersion holes, the second air guide plate 22 is provided with a plurality of second air dispersion holes, and the plurality of first air dispersion holes and the plurality of second air dispersion holes define a first air dispersion area 216. The front panel 16 of the housing 1 is provided with a plurality of third air dispersion holes, and the plurality of third air dispersion holes define a second air dispersion area 161.

[0079] In some further embodiments, the width of the first air guide plate 21 is greater than the width of the second air guide plate 22. When the air-conditioning indoor unit 100 is in a heating state and in a windless mode, the first air guide plate 21 is located below the second air guide plate 22, so that the first air dispersion hole is set downward, so that the first air dispersion area 216 can guide more hot air downward, thereby improving the temperature regulation effect of the air-conditioning indoor unit 100 on the indoor environment.
