[0030] The embodiment of the present application provides an air conditioner indoor unit to solve the problem that a single air outlet and a double air outlet cannot be integrated on one air conditioner. The following will be described with reference to the accompanying drawings.

[0031] In the embodiment of the present application, as shown in Figure 1 and Figure 2 The air conditioner indoor unit comprises:

[0032] The main body 1 is provided with a wind cavity 81, and a first air duct 11, a second air duct 12 and a third air duct 13 which are arranged in communication with the wind cavity 81;

[0033] The first flow dividing piece 2 is movably arranged on the main body 1 and located between the first air duct 11 and the third air duct 13; and

[0034] The second flow dividing piece 3 is movably connected between the second air duct 12 and the third air duct 13;

[0035] When the first flow dividing piece 2 is moved to close the first air duct 11 and the second flow dividing piece 3 is moved to close the second air duct 12, the wind cavity 81 exhausts air through the third air duct 13; when the first flow dividing piece 2 and the second flow dividing piece 3 are moved to close the third air duct 13, the wind cavity 81 exhausts air through the first air duct 11 and the second air duct 12.

[0036] It should be noted that "when the first shunt 2 is moved to close the first air duct 11 and the second shunt 3 is moved to close the second air duct 12, the air cavity 81 exhausts air through the third air duct 13" means that the first shunt 2 closes the first air duct 11, the second shunt 3 closes the second air duct 12, at this time the third air duct 13 is in a flow-through state, and air is exhausted through the third air duct 13. "When the first shunt 2 and the second shunt 3 are moved to mutually connect to close the third air duct 13, the air cavity 81 exhausts air through the first air duct 11 and the second air duct 12" means that the first shunt 2 and the second shunt 3 are moved to the third air duct 13 to jointly close the third air duct 13 and open the first air duct 11 and the second air duct 12, thereby achieving air exhaust.

[0037] It can be understood that the opening or closing of the three air ducts can be achieved by the movement of the first shunt 2 and the second shunt 3, and the air conditioner indoor unit simultaneously has the functions of one-way air exhaust and two-way air exhaust.

[0038] In some embodiments, as shown in Figure 2 and Figure 3 , the first end of the first shunt 2 is rotationally connected to the main body 1, and the second end of the first shunt 2 is movably lapped to the inlet end of the first air duct 11 or the second end of the second shunt 3; the first end of the second shunt 3 is rotationally connected to the main body 1, and the second end of the second shunt 3 is movably lapped to the inlet end of the second air duct 12 or the second end of the first shunt 2.

[0039] It should be noted that the second end of the first shunt 2 movably lapping the inlet end of the first air duct 11 means that the first end of the first shunt 2 is located between the first air duct 11 and the third air duct 13, and the first air duct 11 can be closed by lapping the second end of the first shunt 2 to the inlet end of the first air duct 11; similarly, the second end of the second shunt 3 movably lapping the inlet end of the second air duct 12 means that the first end of the second shunt 3 is located between the second air duct 12 and the third air duct 13, and the second air duct 12 can be closed by lapping the second end of the second shunt 3 to the inlet end of the second air duct 12.

[0040] "The second end of the first shunt 2 movably lapping the second end of the second shunt 3, and the second end of the second shunt 3 movably lapping the second end of the first shunt 2" means that the first shunt 2 and the second shunt 3 jointly close the third air duct 13.

[0041] It can be understood that the swing rotation of the first shunt 2 and the second shunt 3 realizes the switching between one-way air exhaust and two-way air exhaust.

[0042] In some embodiments, as shown in Figure 2 and Figure 3As shown, the air conditioner indoor unit further comprises a first push rod 4 and a second push rod 5; one end of the first push rod 4 is rotationally connected to the first flow dividing piece 2, and the other end of the first push rod 4 is movably connected to the main body 1 to push the first flow dividing piece 2 to rotate between the first air duct 11 and the third air duct 13; one end of the second push rod 5 is rotationally connected to the second flow dividing piece 3, and the other end of the second push rod 5 is movably connected to the main body 1 to push the second flow dividing piece 3 to rotate between the second air duct 12 and the third air duct 13.

[0043] It should be noted that the other end of the first push rod 4 movably connected to the main body 1 means that the end of the first push rod 4 away from the first flow dividing piece 2 moves along a certain trajectory on the main body 1, which can be a straight line or a curve, and here is not limited, as long as the end of the first push rod 4 rotationally connected to the first flow dividing piece 2 rotates around the rotation shaft of the first flow dividing piece 2. The same applies to the other end of the second push rod 5 movably connected to the main body 1.

[0044] It can be understood that the movement of the first push rod 4 and the second push rod 5 drives the rotation of the first flow dividing piece 2 and the second flow dividing piece 3, respectively. In this way, compared with directly driving the rotationally connected end of the first flow dividing piece 2 and the rotationally connected end of the second flow dividing piece 3, it is more efficient and labor-saving.

[0045] Exemplarily, one end of the first push rod 4 is rotationally connected between the first end and the second end of the first flow dividing piece 2; one end of the second push rod 5 is rotationally connected between the first end and the second end of the first flow dividing piece 2. In this way, while improving the driving force of the flow dividing piece rotation, the second end of the first flow dividing piece 2 and the second end of the second flow dividing piece 3 can be avoided.

[0046] In some embodiments, as shown in Figure 2 and Figure 3 As shown, the air conditioner indoor unit further comprises a driving member, the end of the first push rod 4 away from the first flow dividing piece 2 and the end of the second push rod 5 away from the second flow dividing piece 3 are coaxially connected to the driving member, and the driving member is used to drive the end of the first push rod 4 away from the first flow dividing piece 2 and the end of the second push rod 5 away from the second flow dividing piece 3 to move synchronously.

[0047] It should be noted that the driving member can adopt common driving modes such as hydraulic drive, pneumatic drive, electrical drive or mechanical drive, as long as the end of the first push rod 4 away from the first flow dividing piece 2 and the end of the second push rod 5 away from the second flow dividing piece 3 can move.

[0048] It can be understood that by coaxially connecting the first push rod 4 and the second push rod 5 to the same driving member, not only the number of driving sources 6 can be reduced, but also the first push rod 4 and the second push rod 5 can be driven to move synchronously. For example, electric cylinder, air cylinder, etc.

[0049] In some embodiments, asFigure 2 and Figure 3 As shown in FIG. 1, the driving member includes a driving source 6 and a linear motion mechanism 7 connected with the first push rod 4 and the second push rod 5; the driving source 6 is used to drive the linear motion mechanism 7 to move, and the first push rod 4 and the second push rod 5 are synchronously moved in a linear direction away from the first flow dividing member 2 and the second flow dividing member 3.

[0050] It should be noted that the driving source 6 refers to a structure for driving the linear motion mechanism 7 to drive the first push rod 4 and the second push rod 5 to move linearly, such as a motor. The linear motion mechanism 7 is a mechanism for making a certain point on the structure move linearly, such as a ball screw, a synchronous belt, a gear and rack mechanism, etc., and some common linear link mechanisms.

[0051] It can be understood that the first push rod 4 and the second push rod 5 are driven by the linear motion mechanism 7 to move linearly reciprocally, thereby driving the first flow dividing member 2 and the second flow dividing member 3 to rotate.

[0052] In some embodiments, as shown in FIG. 2, the linear motion mechanism 7 includes a gear coaxially connected to the driving source 6 and a rack engaged with the gear, and the first push rod 4 and the second push rod 5 are coaxially hinged to the rack. Figure 2 Figure 3 It should be noted that the first push rod 4 and the second push rod 5 are coaxially hinged to the rack, which means that the first push rod 4 and the second push rod 5 are connected to the rack by hinging, and the rotation axes of the two are coaxial. It can be understood that the driving source 6 drives the gear to rotate, the gear drives the rack to move linearly, and then drives the moving first push rod 4 and the second push rod 5 to drive the first flow dividing member 2 and the second flow dividing member 3 to rotate.

[0053] It should be noted that the first push rod 4 and the second push rod 5 are coaxially hinged to the rack, which means that the first push rod 4 and the second push rod 5 are connected to the rack by hinging, and the rotation axes of the two are coaxial. It can be understood that the driving source 6 drives the gear to rotate, the gear drives the rack to move linearly, and then drives the moving first push rod 4 and the second push rod 5 to drive the first flow dividing member 2 and the second flow dividing member 3 to rotate.

[0054] In some embodiments, as shown in FIG. 3, the third air duct 13 is located between the first air duct 11 and the second air duct 12 and is arranged towards the air outlet of the air cavity 81. Figure 2 It can be understood that when the third air duct 13 is closed, the air output of the first air duct 11 and the second air duct 12 can be balanced as much as possible; when the first air duct 11 and the second air duct 12 are closed, the air outlet of the air cavity 81 can directly discharge from the third air duct 13, reducing air loss and improving the air output of the third air duct 13.

[0055] In some embodiments, as shown in FIG. 4, the third air duct 13 is located between the first air duct 11 and the second air duct 12 and is arranged towards the air outlet of the air cavity 81.

[0056] Figure 3 ​​As shown, the first push rod 4 is located on the side of the first flow divider 2 facing the third air duct 13. It can be understood that, when the first air duct 11 and the second air duct 12 are blowing air, the airflow will reflect on the first flow divider 2 and the second flow divider 3, and at this time, the first push rod 4 is located on the side of the first flow divider 2 away from the air cavity 81, which can provide greater support for the first flow divider 2, so as to avoid the airflow impact force being too large and causing the first flow divider 2 to deform.

[0057] In some embodiments, as shown, Figure 3 As shown, the second push rod 5 is located on the side of the second flow divider 3 facing the third air duct 13. It can be understood that, when the first air duct 11 and the second air duct 12 are blowing air, the airflow will reflect on the first flow divider 2 and the second flow divider 3, and at this time, the second push rod 5 is located on the side of the second flow divider 3 away from the air cavity 81, which can provide greater support for the second flow divider 3, so as to avoid the airflow impact force being too large and causing the second flow divider 3 to deform.

[0058] In some embodiments, as shown, Figure 3 As shown, the first push rod 4 is located on the side of the first flow divider 2 facing the third air duct 13, and the second push rod 5 is located on the side of the second flow divider 3 facing the third air duct 13.

[0059] It can be understood that, when the first air duct 11 and the second air duct 12 are blowing air, the airflow will reflect on the first flow divider 2 and the second flow divider 3, and at this time, the first push rod 4 and the second push rod 5 can provide support for the first flow divider 2 and the second flow divider 3, respectively, so as to avoid the airflow impact force being too large and causing the first flow divider 2 and the second flow divider 3 to deform.

[0060] Further, the driving member is located on the side of the air cavity 81 facing the third air duct 13, and at one end of the third air duct 13 in the length direction. In this way, the driving member can be away from the air outlet of the third air duct 13.

[0061] Still further, the first push rod 4 and the second push rod 5 are located at one end of the third air duct 13 in the length direction, and are connected to one end of the first flow divider 2 and the second flow divider 3 in the length direction, respectively. In this way, the first push rod 4 and the second push rod 5 can be away from the air outlet of the air cavity 81 and the third air duct 13.

[0062] The length direction of the first flow divider 2, the length direction of the second flow divider 3, the length direction of the first air duct 11, the length direction of the second air duct 12, the length direction of the third air duct 13, and the length direction of the air conditioner indoor unit are parallel to each other. The first end and the second end of the first flow divider 2 are the two ends in the length direction, and the first end and the second end of the second flow divider 3 are the two ends in the length direction.

[0063] In some embodiments, the first flow divider 2 comprises a first flow divider plate, and the second flow divider 3 comprises a second flow divider plate; one end or both ends of the first flow divider plate in the length direction thereof is / are connected to one end of the first push rod 4, and one end or both ends of the second flow divider plate in the length direction thereof is / are connected to one end of the second push rod 5.

[0064] In some embodiments, two first push rods 4 are oppositely arranged with respect to both ends of the first flow divider 2 in the length direction thereof, two second push rods 5 are oppositely arranged with respect to both ends of the second flow divider 3 in the length direction thereof, and two driving members are oppositely arranged with respect to both ends of the third air duct 13 in the length direction thereof. In this way, the driving force on the first flow divider 2 and the second flow divider 3 can be improved.

[0065] In some embodiments, the first air duct 11 and the second air duct 12 are arranged on the upper side and the lower side of the main body 1 respectively, and the third air duct 13 is arranged on the front side of the main body 1.

[0066] It should be noted that the upper side, the lower side and the front side refer to different sides of the air conditioner indoor unit after installation. The upper side and the lower side are self-explanatory, and the front side refers to the side of the air conditioner indoor unit facing the user.

[0067] It can be understood that by arranging the third air duct 13 on the front side of the main body 1, the air supply amount of the user's commonly used space height can be increased. Further, by arranging the first air duct 11 and the second air duct 12 on the upper side and the lower side of the main body 1, on the one hand, the air outlet range can be increased, and on the other hand, the cold air or hot air can be delivered to the high altitude and low altitude of the room, thereby maintaining the refrigeration or heating effect of the room.

[0068] In some embodiments, the main body 1 is provided with a cross-flow fan 8, the cross-flow fan 8 is provided with a wind cavity 81, and the driving member is arranged at one end of the cross-flow fan 8 in the axial direction.

[0069] It can be understood that the driving member avoids the air outlet of the cross-flow fan 8, thereby ensuring the air outlet amount of the cross-flow fan 8.

[0070] In the above embodiments, the description of each embodiment focuses on different aspects, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments. In the description of the present application, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include one or more features.
