[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0045] Combination Figure 1-8 As shown, an embodiment of the present disclosure provides an indoor unit of an air conditioner, including a swing blade, a driving member 1 and a transmission 2, wherein the transmission 2 is disposed between the driving member 1 and the swing blade so that the driving member 1 drives the swing blade to move through the transmission 2.

[0046] In the indoor unit of the air conditioner provided by the embodiment of the present disclosure, the transmission 2 is arranged between the driving member 1 and the swing blade, and the driving member 1 can drive the transmission 2 to move to drive the swing blade to move, so as to adjust the rotation angle of the swing blade, thereby adjusting the air outlet direction of the air conditioner. The setting of the transmission 2 can adjust the corresponding torque by changing the speed of the transmission 2, thereby realizing the adjustment of the swing blade speed, which can improve the rotation effect of the swing blade and the air outlet effect of the air conditioner to meet the needs of different users.

[0047] Alternatively, if Figure 3 As shown, the transmission 2 includes an input shaft 21, a first input gear 22, a second input gear 23, an output shaft 24, a first output gear 25 and a second output gear 26. The input shaft 21 is drivingly connected to the driving member 1; the first input gear 22 is arranged on the input shaft 21; the second input gear 23 is arranged on the input shaft 21 and the radius of the first input gear 22 is smaller than the radius of the second input gear 23; the output shaft 24 is arranged parallel to the input shaft 21; the first output gear 25 is arranged on the output shaft 24, corresponding to the first input gear 22, and is used to mesh with or separate from the first input gear 22; the second output gear 26 is arranged on the output shaft 24, corresponding to the second input gear 23, and is used to mesh with or separate from the second input gear 23, and the radius of the first output gear 25 is larger than the radius of the second output gear 26; wherein, the first input gear 22 meshes with the first output gear 25 or the second input gear 23 meshes with the second output gear 26.

[0048] The above embodiment mentioned that the transmission 2 is arranged between the driving member 1 and the pendulum blade, so that the driving member 1 drives the pendulum blade to move through the transmission 2. The driving member 1 is connected to the input shaft 21 of the transmission 2 to drive the input shaft 21 to rotate, thereby driving the first input gear 22 and the second input gear 23 to rotate. The first output gear 25 and the second output gear 26 are respectively arranged corresponding to the first input gear 22 and the second input gear 23, and can be engaged with or separated from the first input gear 22 and the second input gear 23 respectively. When the first input gear 22 and the second input gear 23 rotate under the drive of the input shaft 21, the first output gear 25 and the second output gear 26 can be driven to rotate. The output shaft 24 is arranged parallel to the input shaft 21, and the first output gear 25 and the second output gear 26 are arranged on the output shaft 24, thereby driving the output shaft 24 to rotate to realize the movement of the pendulum blade.

[0049] The radius of the first input gear 22 is smaller than the radius of the second input gear 23. Correspondingly, the radius of the first output gear 25 is larger than the radius of the second output gear 26. When the rotation speed of the input shaft 21 is constant, when the working state inside the transmission 2 changes from the meshing working state of the second input gear 23 and the second output gear 26 to the meshing working state of the first input gear 22 and the first output gear 25, the radius of the first input gear 22 relative to the second input gear 23 decreases, and the radius of the first output gear 25 relative to the second output gear 26 increases. At this time, the rotation speed of the output shaft 24 decreases and the torque increases. When the air conditioner swing blades are stuck and cannot rotate, the increase in torque can enable the swing blades to continue to rotate to adjust the air outlet direction of the air conditioner.

[0050] It can be understood that when the second input gear 23 inside the transmission 2 is meshed with the second output gear 26, the first output gear 25 is loosely sleeved on the output shaft 24. At this time, the first output gear 25 can be meshed with the first input gear 22, but it will not affect the speed of the output shaft 24. Specifically, Figure 4As shown, the second output gear 26 is connected to the output shaft 24 via a spline connection (not shown in the figure) so that the second output gear 26 rotates to drive the output shaft 24 to rotate. When the transmission 2 needs to change from the working state in which the second input gear 23 and the second output gear 26 are meshed to the working state in which the first input gear 22 and the first output gear 25 are meshed, the second output gear 26 is moved along the output shaft 24 to the first output gear 25, and the spline on the inner side of the second output gear 26 is connected to the spline on the outer side of the first output gear 25, so that the second input gear 23 is separated from the second output gear 26, the first input gear 22 is meshed with the first output gear 25, the first input gear 22 drives the first output gear 25 to rotate, the first output gear 25 drives the second output gear 26 to rotate, and the second output gear 26 drives the output shaft 24 to rotate, so as to achieve the effect of reducing the rotation speed of the output shaft 24.

[0051] Alternatively, if Figure 3 As shown, the radius of the second input gear 23 is equal to the radius of the second output gear 26 .

[0052] When the radius of the second input gear 23 is equal to the radius of the second output gear 26, the corresponding input shaft 21 and output shaft 24 have the same rotational speed, and the input torque is equal to the output torque, which can ensure the smooth operation of the transmission 2 and improve the stability of the swing blade movement. Without changing the swing blade rotational speed and torque, the working state in which the second input gear 23 and the second output gear 26 are meshed is adopted, which can improve the service life of the transmission 2, extend the use time of the swing blade and reduce the cost.

[0053] Optionally, the indoor unit of the air conditioner also includes a detection device and a control device. The detection device is arranged corresponding to the swing blade and is used to detect the swing state of the swing blade; the control device is connected to the detection device and is connected to the transmission 2, and is used to control the first input gear 22 to engage with the first output gear 25 when the detection device detects that the swing blade is in a stuck state.

[0054] The setting of the detection device and the control device can prevent the swing blade from being in an abnormal working state for a long time. When the swing blade is stuck, the detection device detects the swinging state of the swing blade and transmits a signal to the control device. The control device changes the working state of the transmission 2 from the meshing of the second input gear 23 and the second output gear 26 to the meshing of the first input gear 22 and the first output gear 25, and the second input gear 23 is separated from the second output gear 26. When the rotation speed of the input shaft 21 is constant, the radius of the first input gear 22 relative to the second input gear 23 decreases, and the radius of the first output gear 25 relative to the second output gear 26 increases. At this time, the rotation speed of the corresponding output shaft 24 decreases and the torque increases, so that the swing blade can continue to rotate to adjust the air outlet direction of the air conditioner.

[0055] Alternatively, if Figure 3 As shown, the transmission 2 also includes a third input gear 27 and a third output gear 28. The third input gear 27 is arranged on the input shaft 21 and the radius of the third input gear 27 is greater than the radius of the second input gear 23; the third output gear 28 is arranged on the output shaft 24 and the radius of the third output gear 28 is smaller than the radius of the second output gear 26; wherein, the first input gear 22 is meshed with the first output gear 25 or the second input gear 23 is meshed with the second output gear 26 or the third output gear 28 is meshed with the third input gear 27.

[0056] The above embodiment mentioned that the transmission 2 is arranged between the driving member 1 and the swing blade, so that the driving member 1 drives the swing blade to move through the transmission 2, the driving member 1 is connected to the input shaft 21 of the transmission 2, so as to drive the input shaft 21 to rotate, thereby driving the third input gear 27 to rotate, and the third output gear 28 is arranged corresponding to the third input gear 27, and can be engaged with or separated from the third input gear 27. The radius of the third input gear 27 is greater than the radius of the second input gear 23, and correspondingly, the radius of the third output gear 28 is smaller than the radius of the second output gear 26. When the speed of the input shaft 21 is constant, when the working state of the transmission 2 is changed from the working state of the second input gear 23 and the second output gear 26 to the working state of the third input gear 27 and the third output gear 28, the radius of the third input gear 27 relative to the second input gear 23 increases, and the radius of the third output gear 28 relative to the second output gear 26 decreases. At this time, the speed of the output shaft 24 increases, which can accelerate the rotation of the swing blade, so as to adjust the air outlet direction of the air conditioner more quickly.

[0057] It can be understood that when the second input gear 23 in the transmission 2 is meshed with the second output gear 26, the third output gear 28 is loosely sleeved on the output shaft 24. At this time, the third output gear 28 can be meshed with the third input gear 27, but it will not affect the speed of the output shaft 24. Specifically, Figure 5 As shown, the second output gear 26 and the output shaft 24 are connected via a spline (not shown in the figure) so that the second output gear 26 rotates to drive the output shaft 24 to rotate.

[0058] When the transmission 2 needs to change from the working state in which the second input gear 23 is meshed with the second output gear 26 to the working state in which the third input gear 27 is meshed with the third output gear 28, the second output gear 26 is moved along the output shaft 24 to the third output gear 28, and the spline on the inner side of the second output gear 26 is connected with the spline on the outer side of the third output gear 28, so that the second input gear 23 is separated from the second output gear 26, and the third input gear 27 is meshed with the third output gear 28, and the third input gear 27 drives the third output gear 28 to rotate, and the third output gear 28 drives the second output gear 26 to rotate, and the second output gear 26 drives the output shaft 24 to rotate, so as to achieve the effect of reducing the rotation speed of the output shaft 24.

[0059] Alternatively, if Figure 6 As shown, the indoor unit of the air conditioner also includes a connecting rod 3 and a frame 4, and the swing blade is arranged on the connecting rod 3; the frame 4 includes a first mounting plate 41 and a second mounting plate 42, and there is an angle between the first mounting plate 41 and the second mounting plate 42 to enclose an installation space 43, the first mounting plate 41 is provided with a first through hole 44 for the connecting rod 3 to pass through, the driving member 1 is arranged on the second mounting plate 42 and is located outside the installation space, and the transmission 2 is connected to one end of the connecting rod 3 in the length direction and is arranged in the installation space 43.

[0060] The driving member 1 is fixed to the second mounting plate 42, the connecting rod 3 is penetrated through the first mounting plate 41 through the first through hole 44, the transmission 2 is arranged in the mounting space 43 surrounded by the first mounting plate 41 and the second mounting plate 42, and the driving member 1, the connecting rod 3 and the transmission 2 are connected to the skeleton 4 through the first mounting plate 41 and the second mounting plate 42. The transmission 2 is driven by the driving member 1 to move, thereby driving the connecting rod 3 to move, thereby driving the swing blade to rotate, so as to adjust the air outlet angle of the air conditioner.

[0061] Alternatively, if Figure 6 As shown, the input shaft 21 and the output shaft 24 are both perpendicular to the connecting rod 3 and are arranged in sequence along the length direction of the connecting rod 3.

[0062] The input shaft 21 and the output shaft 24 are arranged in parallel and are both arranged perpendicular to the connecting rod 3. The extending direction of the connecting rod 3 is the same as the axial direction of the input shaft 21 and the output shaft 24, which can make the movement of the connecting rod 3 smoother. Compared with the parallel arrangement of the connecting rod 3 and the input shaft 21 and the output shaft 24, the phenomenon of the connecting rod 3 having a deviation angle when rotating due to the gravity of the connecting rod 3 can be avoided. When the connecting rod 3 is arranged perpendicular to the input shaft 21 and the output shaft 24, the deviation angle of the connecting rod 3 during rotation will be offset during the rotation, and it can also provide a certain inertia for its own rotation, thereby improving the rotation effect of the connecting rod 3.

[0063] Alternatively, if Figure 1 and Figure 7As shown, the indoor unit of the air conditioner also includes a connecting rod 5, which is connected between the connecting rod 3 and the transmission 2, and one end of the connecting rod 5 is fixedly connected to the transmission 2, and the other end of the connecting rod 5 is rotationally connected to the connecting rod 3.

[0064] The connecting rod 5 includes a first section, a second section and a third section. One end of the first section is connected to the output shaft 24, and the other end is connected to one end of the second section. The other end of the second section is connected to one end of the third section, and the other end of the third section is connected to the connecting rod 3. The first section and the third section are arranged in parallel and parallel to the output shaft 24. The output shaft 24 drives the connecting rod 5 to rotate, so as to drive the connecting rod 3 to rotate with the output shaft 24 as the center and the second section as the radius, so that the connecting rod 3 can be driven by the output shaft 24 to rotate in a smaller space, which can save the overall occupied space and reduce the manufacturing cost of the air-conditioning indoor unit.

[0065] Alternatively, if Figure 8 As shown, the transmission 2 includes a housing 6, a speed-changing element 61 and a gear switch 62, wherein the speed-changing element 61 is disposed in the housing 6; the gear switch 62 is connected to the speed-changing element 61 and is used to adjust the gear of the transmission 2; wherein the housing 6 is provided with a second through hole 63, and the gear switch 62 is disposed in the second through hole 63.

[0066] Specifically, the speed change element 61 includes an input shaft 21 , first, second, and third input gears 22 , 23 , and 27 , and an output shaft 24 , first, second, and third output gears 25 , 26 , and 28 .

[0067] The gear switch 62 is connected to the speed change element 61, so that the adjustment of the gear position of the transmission 2 is more convenient. The gear switch 62 is arranged in the second through hole 63 set in the box body 6. The gear switch 62 at least partially extends out of the through hole, so that there is a force point when the user needs to adjust the gear position of the transmission 2, so that the adjustment of the gear position of the transmission 2 is more convenient and quick.
