Furthermore, both solutions suffer from limited airflow ranges or blind spots. Summary of the Invention

DETAILED DESCRIPTION

[0052] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0053] like Figure 1-Figure 7 As shown, an embodiment of the present application provides an air conditioner indoor unit, including a shell 1 and an air guide plate assembly.

[0054] like Figure 1 As shown, the housing 1 has an air inlet 15 and an air outlet 11. A heat exchange duct 14 is also formed within the housing 1. Its two ends are connected to the air inlet 15 and the air outlet 11, respectively. A heat exchanger 5 and a fan 4 are located within the heat exchange duct 14. Under the action of the fan 4, indoor air can enter the heat exchange duct 14 through the air inlet 15 and exchange heat with the heat exchanger 5. The heat-exchanged air can then be discharged back into the room through the air outlet 11, achieving heating or cooling purposes.

[0055] The air deflector assembly includes a first air deflector 21 and a second air deflector 22 , and the first air deflector 21 and the second air deflector 22 are both rotatably connected to the housing 1 . The air deflector assembly can open or close the air outlet 11 .

[0056] like Figure 2As shown, the air conditioner indoor unit has a mixed air mode. In mixed air mode, the first air guide plate 21 is in a first preset position, the second air guide plate 22 is in a second preset position, and an extended air duct 25 is formed between the first air guide plate 21 and the second air guide plate 22. A gap is formed between the first air guide plate 21 and the housing 1 to form a first air induction channel 23, which connects the upper part of the air outlet 11 with the outside world. A gap is formed between the second air guide plate 22 and the housing 1 to form a second air induction channel 24, which connects the lower part of the air outlet 11 with the outside world. The first air induction channel 23 and the second air induction channel 24 are configured to draw outside air into the extended air duct 25 under the negative pressure created by the airflow from the air outlet 11.

[0057] The indoor unit of the air conditioner in the embodiment of the present application is in Figure 2 In the mixed air mode shown, the first air guide plate 21 and the second air guide plate 22 are respectively rotated to the first preset position and the second preset position to open the air outlet 11; and the first air guide plate 21 can be used as an extension of the upper profile line of the air outlet 11, and the second air guide plate 22 can be used as an extension of the lower profile line of the air outlet 11 to form an extended air duct (diffuser section) 25 between the first air guide plate 21 and the second air guide plate 22. The air outlet 11 can be located upstream of the extended air duct 25, and the air outlet 11 can face the air inlet end of the extended air duct 25, so that the airflow flowing out of the air outlet 11 can enter the extended air duct 25 and then flow back into the room.

[0058] In the mixed air mode, a gap is provided between the first air guide plate 21 at the first preset position and the housing 1 to form a first air induction channel 23, which can connect the upper part of the air outlet 11 with the outside world; a gap is provided between the second air guide plate 22 at the second preset position and the housing 1 to form a second air induction channel 24, which connects the lower part of the air outlet 11 with the outside world. When the air flow flows from the air outlet 11 to the extended air duct 25, a negative pressure is formed. Under the action of the negative pressure, the outside air can pass through the first air induction channel 23 and the second air induction channel 24 and flow into the extended air duct 25 between the first air guide plate 21 and the second air guide plate 22 (the flow direction of the air flow is as shown in FIG. 2 ). Figure 2 In the extended air duct 25, the heat-exchanged air flowing out of the air outlet 11 can be mixed with the unheated air entering from the first air induction channel 23 and the second air induction channel 24. In this way, when the air conditioner is cooling, the air blown out through the extended air duct 25 is a mixture of heat-exchanged cold air and unheated room temperature air. The temperature of this mixed air is not too low, thereby avoiding the discomfort caused by the cold air blowing directly on people.

[0059] In addition, an extended air duct 25 is formed between the first air guide plate 21 and the second air guide plate 22, which can slow down the diffusion of the air flow, increase the air supply distance, reduce the air volume attenuation at the air outlet 11, and improve the cooling effect.

[0060] The indoor unit of the air conditioner in the embodiment of the present application improves the comfort during cooling while ensuring the cooling effect by providing the first air guide plate 21 and the second air guide plate 22, the first air induction channel 23 and the second air induction channel 24 and the mixed air mode.

[0061] In some exemplary embodiments, in the mixed air mode, the gap between the first air guide plate 21 and the housing 1 is 4 mm-15 mm; and / or, in the mixed air mode, the gap between the second air guide plate 22 and the housing 1 is 4 mm-25 mm.

[0062] In mixed air mode, the gap ε1 between the first air guide plate 21 and the housing 1 (the first air induction channel 23) is 4mm-15mm (4mm≤ε1≤15mm), such as 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc. If the gap is too small, the air induction and air mixing effects will be affected; if the gap is too large, it will cause air leakage during normal air supply in other operating modes (such as the first no-wind mode, the second no-wind mode, and the heating mode described below), and affect the overall appearance of the air conditioner indoor unit.

[0063] In mixed air mode, the gap ε2 between the second air guide plate 22 and the housing 1 (the second air induction channel 24) is 4mm-25mm (4mm≤ε2≤25mm), such as 4mm, 7mm, 10mm, 12mm, 15mm, 18mm, 20mm, 22mm, 25mm, etc. If the gap is too small, the air induction and mixed air effects will be affected; if the gap is too large, it will cause air leakage during normal air supply in other operating modes (such as the first no-wind mode, the second no-wind mode, the cooling mode, the heating mode, and the anti-direct blowback mode described below), and affect the overall appearance of the air conditioner indoor unit.

[0064] In some exemplary embodiments, Figure 2 As shown, in the mixed air mode, the angle A1 between the air guide surface of the first air guide plate 21 (the first air guide surface 213) and the upper end surface 111 of the air outlet 11 is greater than 180 degrees; and / or, the angle B1 between the air guide surface of the second air guide plate 22 (the second air guide surface 221) and the lower end surface 112 of the air outlet 11 is greater than 180 degrees. For example, in a specific embodiment, in the mixed air mode, one end of the first air guide surface 213 of the first air guide plate 21 is close to the air outlet 11, and the end of the first air guide surface 213 of the first air guide plate 21 away from the air outlet 11 is inclined forward and downward; and / or, in the mixed air mode, one end of the second air guide surface 221 of the second air guide plate 22 is close to the air outlet 11, and the end of the second air guide surface 221 of the second air guide plate 22 away from the air outlet 11 is inclined forward and downward.

[0065] The angle A1 between the first air guide surface 213 of the first air guide plate 21 and the upper end surface 111 of the air outlet 11 is greater than 180 degrees, that is, the first air guide plate 21 is slightly opened upward relative to the upper end surface 111 of the air outlet 11. The angle B1 between the second air guide surface 221 of the second air guide plate 22 and the lower end surface 112 of the air outlet 11 is greater than 180 degrees, that is, the second air guide plate 22 is slightly opened downward. Due to the provision of the first air induction channel 23 and the second air induction channel 24, the air blown out of the extended air duct 25 is mixed air. The temperature of the mixed air is slightly higher than the temperature of the unmixed cold air blown out of the air outlet 11. Therefore, the second air guide plate 22 is slightly opened downward.

[0066] In some exemplary embodiments, Figure 2 As shown, in the air mixing mode, the first air guide surface 213 of the first air guide plate 21 and the second air guide surface 221 of the second air guide plate 22 gradually move away from each other along the air flow direction in the extended air duct 25 .

[0067] In the mixed air mode, the first air guide surface 213 of the first air guide plate 21 and the second air guide surface 221 of the second air guide plate 22 gradually move away from each other along the direction of air flow in the extended air duct 25, so that the wind speed of the mixed air gradually decreases when flowing through the extended air duct 25. The mixed air can be dispersed at a faster speed, and the cold air blown out is softer.

[0068] It should be understood that the inclination angles of the first air guide plate 21 and its first air guide surface 213, and the second air guide plate 22 and its second air guide surface 221 are not limited to the above, and can be adjusted as needed on the premise of maximizing the gap between the first air duct 23 and the second air duct 24 to meet the air mixing requirements.

[0069] In some exemplary embodiments, Figure 1 As shown, the first end of the first air guide plate 21 is rotatably connected to the shell 1, and the first end of the first air guide plate 21 is located in the front and upper part of the air outlet 11; the first end of the second air guide plate 22 is rotatably connected to the shell 1, and the first end of the second air guide plate 22 is located in the front and lower part of the air outlet 11.

[0070] In some exemplary embodiments, Figure 1 As shown, the range of the rotation angle of the first air guide plate 21 (i.e., the maximum rotation angle of the first air guide plate 21) A0 is not less than 180 degrees; and / or the range of the rotation angle of the second air guide plate 22 (i.e., the maximum rotation angle of the second air guide plate 22) B0 is not less than 180 degrees. In a specific embodiment, the maximum rotation angle of the first air guide plate 21 and the maximum rotation angle of the second air guide plate 22 are both greater than or equal to 180 degrees. The first air guide plate 21 can be Figure 1 The position shown by the solid line is rotated to the position shown by the dotted line. At this time, the first air guide plate 21 reaches the maximum rotation angle; the second air guide plate 22 can be rotated by Figure 1 The position indicated by the solid line rotates to the position indicated by the dotted line, at which time the second air guide plate 22 reaches the maximum rotation angle.

[0071] The first air guide plate 21 and the second air guide plate 22 have a rotational angle range of no less than 180 degrees, so that the first air guide plate 21 and the second air guide plate 22 can cooperate to form a variety of air guide structures, thereby enabling the air conditioner indoor unit to have multiple operating modes. The first end of the first air guide plate 21 is rotatably connected to the housing 1, and the rotational angle range of the first air guide plate 21 is no less than 180 degrees. The two cooperate to minimize or prevent the first end of the first air guide plate 21 from exceeding the plane of the upper end surface 111 of the air outlet 11 during rotation, thereby causing wind blocking and affecting the air outlet effect of the air outlet 11. The first end of the second air guide plate 22 is rotatably connected to the housing 1, and the rotational angle range of the second air guide plate 22 is no less than 180 degrees. The two cooperate to minimize or prevent the first end of the second air guide plate 22 from exceeding the plane of the lower end surface 112 of the air outlet 11 during rotation, thereby causing wind blocking and affecting the air outlet effect of the air outlet 11.

[0072] In some exemplary embodiments, Figure 1 and Figure 1a As shown, the housing 1 includes a first curved wall 12, the first curved wall 12 is located in front of and above the air outlet 11, the first end of the first air guide plate 21 is arranged in front of the first curved wall 12, and the first curved wall 12 is arranged to avoid the first end of the first air guide plate 21 when the first air guide plate 21 rotates; Figure 2 In the air mixing mode shown, a gap is provided between the first curved wall 12 and the first air guide plate 21 to form a first air induction channel 23 .

[0073] The housing 1 may include a face frame 17 and a panel 16 fixed to the front side of the face frame 17. The first curved wall 12 may be integrally formed on the lower side of the panel 16, and the first curved wall 12 is located in front of the air outlet 11 and behind the panel 16. The first curved wall 12 may be recessed toward the rear side to form a space in front of the first curved wall 12 for positioning the first end of the first air guide plate 21. The first curved wall 12 does not interfere with the first end of the first air guide plate 21 during rotation of the first air guide plate 21. In the air mixing mode, the first air guide plate 21 rotates to a first preset position, and the first air guide plate 21 and the first curved wall 12 do not contact each other, with a gap between them forming a first air induction channel 23.

[0074] Of course, the first arc-shaped wall 12 can also be integrally formed with the surface frame 17 .

[0075] In some exemplary embodiments, Figure 1 and Figure 1bAs shown, the housing 1 is provided with a second curved wall 13, the second curved wall 13 is located below the air outlet 11, the first end of the second air guide plate 22 is provided in front of the second curved wall 13, and the second curved wall 13 is provided to avoid the first end of the second air guide plate 22 when the second air guide plate 22 rotates; Figure 2 In the air mixing mode shown, there is a gap between the second curved wall 13 and the second air guide plate 22 to form a second air induction channel 24 .

[0076] The second curved wall 13 can be integrally formed with the face frame 17 and positioned below the air outlet 11. The second curved wall 13 can be recessed toward the rear to create a space in front of the second curved wall 13 for the first end of the second air guide plate 22. The second curved wall 13 does not interfere with the first end of the second air guide plate 22 during its rotation. In the air mixing mode, the second air guide plate 22 rotates to a second predetermined position, and the second air guide plate 22 and the second curved wall 13 do not contact each other, with a gap between them forming a second air induction channel 24.

[0077] In some exemplary embodiments, Figure 1b As shown, the distance between the rotation center of the second air guide plate 22 and the lower profile line of the air outlet 11 is L1, and the distance between the rotation center of the second air guide plate 22 and the end of the first end of the second air guide plate 22 is L2, L1≥L2.

[0078] The first end of the second air guide plate 22, which is rotatably connected to the shell 1, is located in the front and lower part of the air outlet 11, and the distance L1 between the rotation center of the second air guide plate 22 and the lower mold line of the air outlet 11 is ≥ the distance L2 between the rotation center of the second air guide plate 22 and the end of the first end of the second air guide plate 22, so that when the second air guide plate 22 rotates around its rotation center, the first end of the second air guide plate 22 exceeds the plane where the lower end surface 112 of the air outlet 11 is located, thereby causing wind blocking and affecting the air outlet effect of the air outlet 11.

[0079] In some exemplary embodiments, the first air guide plate 21 and the second air guide plate 22 are both provided with ventilation holes, which may be circular holes, diamond holes, conical holes, or holes of other shapes.

[0080] like Figure 3 As shown, the air conditioner indoor unit also has a first no-wind mode. In the first no-wind mode, the first air guide plate 21 is in the third preset position, the second air guide plate 22 is in the fourth preset position, and the second end of the first air guide plate 21 opposite to the first end is in contact with the second end of the second air guide plate 22 opposite to the first end.

[0081] like Figure 3As shown, when the indoor unit of the air conditioner is in the first windless mode, the first air guide plate 21 is in the third preset position, the second air guide plate 22 is in the fourth preset position, and the first end of the first air guide plate 21 is located in the front and upper part of the air outlet 11, the first end of the second air guide plate 22 is located in the front and lower part of the air outlet 11, and the second end of the first air guide plate 21 and the second end of the second air guide plate 22 are in contact with each other. At this time, the first air guide plate 21 and the second air guide plate 22 can cooperate to almost completely block the air outlet 11, and the cold air blown out from the air outlet 11 can be dispersed through the ventilation holes on the first air guide plate 21 and the second air guide plate 22 and then flow into the room to achieve windless cooling.

[0082] In some exemplary embodiments, Figure 3 As shown, in the first no-wind mode, the second end of the second air guide plate 22 is inclined forward and downward, and the second end of the first air guide plate 21 extends downward and can contact the second end of the second air guide plate 22.

[0083] In some exemplary embodiments, Figure 1 and Figure 4 As shown, the air conditioner indoor unit also has a second, no-wind mode. In this second, no-wind mode, the positions of the first and second air guide plates 21, 22 are the same as when the air conditioner indoor unit is off. In this second, no-wind mode or off state, the second end of the first air guide plate 21, opposite to the first end, tilts downward and rearward and contacts the first end of the second air guide plate 22. The second end of the second air guide plate 22, opposite to the first end, extends horizontally rearward.

[0084] The indoor unit of the air conditioner is in Figure 4 In the second no-wind mode shown, the first wind guide plate 21 is in the same Figure 1 The first initial position is the same as the shutdown state shown in FIG. Figure 1 The second initial position is the same as the shutdown state shown, and the first end of the second air guide plate 22 is located in the front and lower part of the air outlet 11, and the second end of the second air guide plate 22 extends horizontally backward. The first end of the first air guide plate 21 is located in the front and upper part of the air outlet 11, and the second end of the first air guide plate 21 is inclined toward the rear and lower part, and the second end of the first air guide plate 21 is in contact with the first end of the second air guide plate 22. At this time, the first air guide plate 21 and the second air guide plate 22 can cooperate to almost completely block the air outlet 11, and the cold air blown out from the air outlet 11 can be dispersed through the ventilation holes on the first air guide plate 21 and the second air guide plate 22 and then flow into the room to achieve windless cooling.

[0085] In some exemplary embodiments, Figure 1 and Figure 4As shown, a groove 171 is provided on the lower wall of the shell 1 . In the second windless mode, the second end of the second air guide plate 22 is accommodated in the groove 171 , and the lower plate surface of the second air guide plate 22 is flush with the lower wall of the shell 1 .

[0086] In a specific example, a groove 171 is provided on the lower surface of the face frame 17, and the front end of the groove 171 is through. In the second windless mode (or shutdown state), the second end of the second air guide plate 22 can be accommodated in the groove 171, so that in the second windless state, the portion of the second air guide plate 22 accommodated in the groove 171 is blocked by the face frame 17, and the ventilation holes on the blocked portion of the second air guide plate 22 cannot be used to discharge cold air; the portion of the second air guide plate 22 not accommodated in the groove 171 is not blocked by the face frame 17, and the ventilation holes on the unblocked portion of the second air guide plate 22 can be used to discharge cold air.

[0087] In the first no-wind mode and the second no-wind mode, the size and direction of the cold air are different. In the first no-wind mode, part of the cold air blown out from the air outlet 11 can be blown forward and upward through the ventilation holes on the first air guide plate 21, and part of the cold air can be blown backward and downward through the ventilation holes on the second air guide plate 22 (the flow direction of the cold air is as follows Figure 3 In the second windless mode, part of the cold air blown out from the air outlet 11 can be blown forward and upward through the ventilation holes on the first air guide plate 21, and part of the cold air can be blown downward through the ventilation holes on the second air guide plate 22 (the flow direction of the cold air is as shown in FIG. Figure 4 (indicated by the arrow in the middle).

[0088] and Figure 3 Compared with the first no-wind mode shown, Figure 4 In the second windless mode, the number of vents for discharging cool air on the second air guide plate 22 is reduced, and less cool air is blown downward through the second air guide plate 22. Therefore, the air conditioner indoor unit (on-hook unit) can be mounted on a wall and positioned above the head of a bed. The overall cool air output in the second windless mode is reduced compared to the first windless mode. In the first windless mode, cool air is primarily discharged downward, forward, and upward, while in the second windless mode, cool air is primarily discharged upward and forward.

[0089] The lower surface of the second air deflector 22, housed within the recess 171, is flush with the lower wall of the face frame 17, helping to maintain a smooth and aesthetically pleasing appearance of the air conditioner indoor unit. In the second windless mode or when the unit is off, the first air deflector 21 primarily shields the air outlet 11, while the second air deflector 22 abuts against the face frame 17, maintaining a smooth appearance.

[0090] In some exemplary embodiments, Figure 5As shown, the air conditioner indoor unit also has a cooling mode. In cooling mode, the first air guide plate 21 is in the fifth preset position, the second air guide plate 22 is in the sixth preset position, the second end of the first air guide plate 21, opposite to the first end, is tilted forward and upward, and an angle A2 between the first air guide surface 213 of the first air guide plate 21 and the upper end surface 111 of the air outlet 11 is greater than 180 degrees; the second end of the second air guide plate 22, opposite to the first end, extends forward, and an angle B2 between the second air guide surface 221 of the second air guide plate 22 and the lower end surface 112 of the air outlet 11 is less than 180 degrees.

[0091] The indoor unit of the air conditioner is in Figure 5 In the cooling mode shown, the first air guide plate 21 and the second air guide plate 22 rotate to the fifth preset position and the sixth preset position respectively, and the angle A2 between the first air guide surface 213 of the first air guide plate 21 in the fifth preset position and the upper end surface 111 of the air outlet 11 is greater than 180 degrees, and the angle B2 between the second air guide plate 22 of the second air guide plate 22 in the sixth preset position and the lower end surface 112 of the air outlet 11 is less than 180 degrees, that is, the first air guide surface 213 of the first air guide plate 21 rotates upward by a certain angle relative to the upper end surface 111 of the air outlet 11, and the second air guide surface 221 of the second air guide plate 22 rotates upward by a certain angle relative to the lower end surface 112 of the air outlet 11, so that upward air can be guided by the first air guide plate 21 and the second air guide plate 22, thereby realizing shower-style blowing, avoiding cold air blowing directly on people, and improving comfort.

[0092] In some exemplary embodiments, Figure 5 As shown, in the cooling mode, the plate surface of the first air guide plate 21 which is away from the first air guide surface 213 contacts the housing 1 to close the gap between the first air guide plate 21 and the housing 1 .

[0093] like Figure 5 As shown, when the air conditioner indoor unit is in cooling mode, the surface of the first air guide plate 21 that is opposite to the first air guide surface 213 can contact the bottom end of the panel 16 to close the gap between the first air guide plate 21 and the housing 1, thereby preventing air from being drawn in through the gap between the first air guide plate 21 and the housing 1, or preventing cold air from being blown out through the gap between the first air guide plate 21 and the housing 1. In cooling mode, the second air guide plate 22 can serve as an extension of the lower profile of the air outlet 11, and an extended air duct (diffuser section) can be formed between the first air guide plate 21 and the second air guide plate 22, which helps to improve the cooling effect.

[0094] In some exemplary embodiments, Figure 6 As shown, the air conditioner indoor unit also has an anti-direct blowing mode. In the anti-direct blowing mode, the first air guide plate 21 is in the seventh preset position, the second air guide plate 22 is in the eighth preset position, and the second end of the second air guide plate 22 opposite to the first end is tilted forward and upward.

[0095] like Figure 6 As shown, when the air conditioner indoor unit is in the anti-direct blowing mode, the first air guide plate 21 and the second air guide plate 22 are rotated to the seventh preset position and the eighth preset position respectively, and the first end of the second air guide plate 22 in the seventh preset position is located in the front and lower part of the air outlet 11, and the two ends are tilted toward the front and upper part to guide the cold air blown out of the air outlet 11 upward, preventing the cold air from blowing directly downward onto people, thereby improving comfort.

[0096] In some exemplary embodiments, Figure 6 As shown, in the direct blowing prevention mode, the plate surface of the first air guide plate 21 which is away from the first air guide surface 213 contacts the housing 1 to close the gap between the first air guide plate 21 and the housing 1 .

[0097] In the air conditioner indoor unit of the embodiment of the present application, in cooling mode and direct blowback prevention mode, the surface of the first air guide plate 21 that is opposite the first air guide surface 213 contacts the housing 1, thereby closing the gap between the first air guide plate 21 and the housing 1. That is, the seventh preset position and the fifth preset position of the first air guide plate 21 are the same position. In direct blowback prevention mode, closing the gap between the first air guide plate 21 and the housing 1 prevents air from being drawn in through the gap between the first air guide plate 21 and the housing 1, or preventing cold air from being blown out through the gap between the first air guide plate 21 and the housing 1.

[0098] In some exemplary embodiments, Figure 5 and Figure 6 As shown, in the cooling mode, the angle between the second air guide surface 221 of the second air guide plate 22 and the lower end surface 112 of the air outlet 11 is B2, and in the anti-direct blowing mode, the angle between the second air guide surface 221 of the second air guide plate 22 and the lower end surface 112 of the air outlet 11 is B3, B2>B3.

[0099] The second air guide plate 22 in the anti-direct blowing mode rotates further upward relative to the second air guide plate 22 in the cooling mode. Therefore, the second air guide plate 22 can further slow down the downward blowing of cold air, thereby achieving a good effect of preventing cold air from directly blowing on the human body.

[0100] In some exemplary embodiments, Figure 7 As shown, the air conditioner indoor unit also has a heating mode. In the heating mode, the first air guide plate 21 is in the ninth preset position, the second air guide plate 22 is in the tenth preset position, the second end of the first air guide plate 21, opposite to the first end, extends downward, and the angle A4 between the first air guide surface 213 of the first air guide plate 21 and the upper end surface 111 of the air outlet 11 is less than 180 degrees; the second end of the second air guide plate 22, opposite to the first end, extends downward, and the angle B4 between the second air guide surface 221 of the second air guide plate 22 and the lower end surface 112 of the air outlet 11 is greater than 180 degrees.

[0101] When the air conditioner indoor unit is in heating mode, the first air guide plate 21 and the second air guide plate 22 rotate to a ninth preset position and a tenth preset position, respectively. In the ninth preset position, the first end of the first air guide plate 21 is located above and in front of the air outlet 11, the second end of the first air guide plate 21 extends downward, and an angle A4 between the first air guide surface 213 of the first air guide plate 21 and the upper end surface 111 of the air outlet 11 is less than 180 degrees, i.e., the first air guide surface 213 of the first air guide plate 21 is rotated downward by a certain angle relative to the upper end surface 111 of the air outlet 11. In the tenth preset position, the first end of the second air guide plate 22 is located below and in front of the air outlet 11, the second end of the second air guide plate 22 extends downward, and an angle B4 between the second air guide surface 221 of the second air guide plate 22 and the lower end surface 112 of the air outlet 11 is greater than 180 degrees, i.e., the second air guide surface 221 of the second air guide plate 22 is rotated downward by a certain angle relative to the lower end surface 112 of the air outlet 11.

[0102] The first air guide plate 21 can serve as an extension of the upper mold line of the air outlet 11, and the second air guide plate 22 can serve as an extension of the lower mold line of the air outlet 11. An extended air duct (diffuser section) can be formed between the first air guide plate 21 and the second air guide plate 22. Downward air discharge can be achieved through the extended air duct, which is conducive to achieving carpet-style blowing and improving the heating effect.

[0103] In some exemplary embodiments, Figure 1 and Figure 1a As shown, the first air deflector 21 includes an air deflector body 211 and a bent portion 212 disposed at one end of the air deflector body 211. The end of the first air deflector 21 near the bent portion 212 is the first end of the first air deflector 21, and the first end of the first air deflector 21 is rotatably connected to the housing 1. When the air conditioner indoor unit is off, the bent portion 212 is located on the side of the air deflector body 211 near the panel 16, and the end of the bent portion 212 away from the air deflector body 211 extends toward the panel 16.

[0104] like Figure 1 and Figure 1a As shown, when the air conditioner indoor unit is in the off state, the first air guide plate 21 can be in the first initial position. At this time, the bent portion 212 is located on the upper side of the air guide plate body 211 and is in a vertical position. The upper end of the bent portion 212 can be close to the lower end of the panel 16. The provision of the bent portion 212 helps to reduce the gap between the first air guide plate 21 and the panel 16, enhances the aesthetics of the air conditioner indoor unit, and helps prevent dust from entering the housing 1 through the gap between the first air guide plate 21 and the panel 16.

[0105] In some exemplary embodiments, Figure 1 and Figure 1aAs shown, the angle between the air guide plate body 211 and the bent portion 212 is less than 180 degrees.

[0106] like Figure 1 and Figure 1a As shown, when the indoor unit of the air conditioner is in the off state, the bent portion 212 can be in a vertical state, and the lower end of the air guide plate body 211, which has an angle less than 180 degrees with the bent portion 212, can be tilted obliquely backward to block the air outlet 11.

[0107] In some exemplary embodiments, Figure 1 As shown, the air conditioner indoor unit further includes a first driving mechanism 31 and a second driving mechanism 32 . The first driving mechanism 31 is configured to drive the first air guide plate 21 to rotate, and the second driving mechanism 32 is configured to drive the second air guide plate 22 to rotate.

[0108] The embodiment of the present application further provides an air conditioner, comprising the air conditioner indoor unit described in any of the above embodiments. The air conditioner indoor unit can be a wall mounted unit.

[0109] To sum up, the indoor unit of the air conditioner in the embodiment of the present application forms a variety of air supply modes by combining two air guide plates (the first air guide plate 21 and the second air guide plate 22) in different positions, which can improve the cooling and heating effects, bring new comfort effects, and at the same time increase the air supply range, improve comfort, and enhance user experience.
