[0052] Figure 1 is the schematic structural diagram of the guide plate closing the air outlet according to one embodiment of the utility model, as Figure 1 shown, and referring to Figures 2 to 8 , the utility model embodiment provides a kind of air conditioner indoor unit 100, including shell 10, guide plate assembly and connecting rod 430, and air outlet 20 is set in shell 10.Guide plate assembly includes push rod 440 and the guide plate 30 of being arranged in the front end of push rod 440, and guide plate 30 is used to guide the airflow flowing out at air outlet 20.Push rod 440 is telescopically arranged on shell 10.Connecting rod 430 is rotatably installed on shell 10, and connecting rod 430 includes first extrusion surface 451 and second extrusion surface 452, and when connecting rod 430 rotates to first direction, first extrusion surface 451 is extruded with push rod 440 and drives push rod 440 to extend.Connecting rod 430 rotates to second direction opposite to first direction, and second extrusion surface 452 is extruded with push rod 440 and drives push rod 440 to retract.

[0053] In the embodiment, when connecting rod 430 rotates to first direction, because first extrusion surface 451 is extruded with push rod 440, push rod 440 slides along first extrusion surface 451, so that push rod 440 extends to the direction close to the front end of push rod 440, to make guide plate 30 open air outlet 20.When connecting rod 430 rotates to second direction, because second extrusion surface 452 is extruded with push rod 440, push rod 440 slides along second extrusion surface 452, so that push rod 440 retracts to the direction away from the front end of push rod 440, to make guide plate 30 close air outlet 20.Push rod 440 and connecting rod 430 push guide plate 30 from air outlet 20, avoid the situation that guide plate 30 shields air outlet 20, to reduce the situation that heat exchange air blows to guide plate 30, make heat exchange air out more smoothly, prevent guide plate 30 from affecting air outlet angle and air outlet volume, improve the air outlet effect of air conditioner indoor unit 100.Moreover, guide plate 30 is pushed out from air outlet 20, reduce the obstruction of guide plate 30 to air outlet, to reduce the noise generated by heat exchange air blowing to guide plate 30.

[0054] In some other embodiments of this utility model, a connecting rod 430 and a push rod 440 form a group. The connecting rod 430 and push rod 440 can be a single group or multiple groups. When multiple groups are set, the multiple push rods 440 are respectively connected to different parts of the guide plate 30, and move synchronously to drive the guide plate 30 to translate. This makes the movement of the guide plate 30 more stable, especially for long, narrow guide plates 30. Furthermore, when multiple groups are set, only one group needs to be able to drive the guide plate 30 to move; it is not necessary for each group to have the function of driving the guide plate 30 to move.

[0055] Furthermore, in some embodiments of this utility model, such as Figure 1 As shown, the guide plate 30 is a long strip extending laterally. There are two connecting rods 430 and two push rods 440 respectively. The two push rods 440 are connected to the two ends of the guide plate 30 laterally, that is, the two ends of the guide plate 30 in the length direction.

[0056] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the push rod 440 has a slider on the side near the connecting rod 430. The connecting rod 430 has an arc-shaped channel 450, and the two opposite sidewalls of the arc-shaped channel 450 are a first extrusion surface 451 and a second extrusion surface 452, respectively.

[0057] In this embodiment, the connecting rod 430 has an arc-shaped channel 450, and the slider slides within the arc-shaped channel 450 to drive the push rod 440 to extend and retract. When the connecting rod 430 rotates in the first direction, the first pressing surface 451 presses against the slider, and the slider slides along the first pressing surface 451, causing the push rod 440 to be pushed out towards the front end of the push rod 440, thereby causing the guide plate 30 to open the air outlet 20. When the connecting rod 430 rotates in the second direction, the second pressing surface 452 presses against the slider, and the slider slides along the second pressing surface 452, causing the push rod 440 to retract away from the front end of the push rod 440, thereby causing the guide plate 30 to close the air outlet 20. The connection structure between the connecting rod 430 and the push rod 440 is simple, the transmission is stable, and the movement of the guide plate 30 is relatively stable.

[0058] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the two end faces of the arc-shaped channel 450 are the first limiting surface 453 and the second limiting surface 454, respectively. When the guide plate 30 fully opens the air outlet 20, the first limiting surface 453 abuts against the slider. When the guide plate 30 closes the air outlet 20, the second limiting surface 454 abuts against the slider.

[0059] In the embodiment, the arc-shaped channel 450 is formed by the first limiting surface 453, the first extrusion surface 451, the second limiting surface 454 and the second extrusion surface 452. When the connecting rod 430 rotates to the first direction, the first extrusion surface 451 extrudes the sliding block, the sliding block slides along the first extrusion surface 451, the push rod 440 is pushed to the direction close to the front end of the push rod 440, so as to drive the guide plate 30 to open the air outlet 20, and when the sliding block slides to the position abutting against the first limiting surface 453, the guide plate 30 completely opens the air outlet 20. When the connecting rod 430 rotates to the second direction, the second extrusion surface 452 extrudes the sliding block, the sliding block slides along the second extrusion surface 452, the push rod 440 is retracted to the direction away from the front end of the push rod 440, so as to drive the guide plate 30 to close the air outlet 20, and when the sliding block slides to the position abutting against the second limiting surface 454, the guide plate 30 closes the air outlet 20. The arc-shaped channel 450 not only realizes the extension and retraction of the push rod 440 through extrusion of the sliding block, but also limits the continuous sliding of the sliding block when the guide plate 30 is completely opened or closed, so that the limiting structure does not need to be additionally arranged, the connecting structure of the guide plate assembly is relatively simple, and then the space utilization of the air conditioner indoor unit 100 is improved.

[0060] In some embodiments of the utility model, as shown in Figure 1 The air outlet 20 is arranged on the front surface of the shell 10. The shell 10 comprises a mounting plate 160, and the mounting plate 160 is provided with a through hole through which the push rod 440 passes, and the axis of the through hole gradually inclines upward from back to front.

[0061] In the embodiment, the through hole gradually inclines upward from back to front, the push rod 440 extends forward and upward when extending, that is, the guide plate 30 moves forward and upward, so that the air outlet 20 is opened. The push rod 440 retracts backward and downward when retracting, that is, the guide plate 30 moves backward and downward, so that the air outlet 20 is closed. The push rod 440 slides in the through hole to limit the extension and retraction direction of the push rod 440, so that the extension and retraction process of the push rod 440 is relatively stable and smooth.

[0062] In some embodiments of the utility model, as shown in Figure 5 The rear side of the air outlet 20 at both ends is provided with a baffle 120 abutting against the guide plate 30, and the baffle 120 is provided with a gap slot 130 or a gap hole 140.

[0063] In the embodiment, the rear side of the air outlet 20 is provided with the baffle 120, when the guide plate 30 closes the air outlet 20, the guide plate 30 abuts against the baffle 120, so that the front surface of the guide plate 30 is flush with the front surface of the shell 10, so that the appearance of the air conditioner indoor unit 100 is more complete and beautiful.

[0064] In some embodiments of the utility model, as shown in Figure 5As shown, the connecting protrusion 80 is arranged at the rear side of the guide plate 30, and is located at the position of the gap slot 130 or the gap hole 140 when the guide plate 30 closes the air outlet 20.

[0065] In the embodiment, the connecting protrusion 80 is located at the gap hole 140 when the guide plate 30 closes the air outlet 20. The connecting protrusion 80 is triangular, and the push rod 440 is pushed forward and upward to push the guide plate 30 and the connecting protrusion 80 forward and upward, and the upper side of the connecting protrusion 80 has a small angle with the guide plate 30, so that the connecting protrusion 80 is easily moved forward and upward, and the upper side of the connecting protrusion 80 is prevented from colliding with the upper wall of the gap slot 130 or the gap hole 140, thereby preventing the guide plate 30 from being stuck when opening or closing the air outlet 20.

[0066] In some embodiments of the utility model, as shown in Figure 1 As shown, the air conditioner indoor unit 100 further comprises at least one driving mechanism 60, which is arranged at the front end of the push rod 440 and is used to drive the guide plate 30 to rotate. The driving mechanism comprises a motor 610, a first gear 620 and a second gear 630. The motor 610 is installed at the front end of the push rod 440. The first gear 620 is connected with the output end of the motor 610. The second gear 630 is engaged with the first gear 620 to drive the second gear 630 to rotate with the first gear 620. The output shaft 631 of the second gear 630 is rotatably installed on the push rod 440, and the output shaft 631 is connected with the connecting protrusion 80 to drive the guide plate 30 to rotate by the motor 610.

[0067] In the embodiment, the air conditioner indoor unit 100 further comprises at least one driving mechanism 60, which is arranged at the front end of the push rod 440. When the push rod 440 pushes the guide plate 30 out of the air outlet 20, the driving mechanism 60 is operated to drive the guide plate to rotate up and down. When the driving mechanism 60 is operated, the motor 610 drives the first gear 620 to rotate, thereby driving the second gear 630 to rotate, and further driving the guide plate 30 to rotate. When the guide plate 30 is rotated to a horizontal position or an upward angle, the heat exchange air is blown out of the air outlet 20, and the guide plate 30 does not affect the blowing out of the heat exchange air, thereby preventing the guide plate 30 from affecting the air volume of the heat exchange air. The guide plate 30 has other rotation angles to guide the blowing out of the heat exchange air, thereby preventing the heat exchange air from directly blowing on the user.

[0068] In some other embodiments of the utility model, when the push rod 440 is one, the driving mechanism 60 is provided with one. When the push rod 440 is multiple, the driving mechanism 60 is arranged on one of the push rods 440. Alternatively, the driving mechanism 60 is arranged on part of the push rods 440 or all of the push rods 440.

[0069] Further, in some embodiments of the utility model, the push rod 440 is provided with two, one of which is provided with a driving mechanism 60, saving the production and operation cost of the air conditioner indoor unit 100, simplifying the control of the guide plate 30.

[0071] In this embodiment, the driving mechanism 60 is clamped with the connecting protrusion 80 through the first clamping part 710 and the second clamping part 720. The outer side wall of the first clamping part 710 has at least one plane, and the inner wall surface of the connecting hole is matched with the outer wall surface of the first clamping part 710, preventing the first clamping part 710 from rotating relative to the connecting protrusion 80, so that the rotation of the first clamping part 710 can drive the guide plate 30 to rotate. The upper end of the second clamping part 720 has a clamping jaw 721, and after the second clamping part 720 penetrates into the connecting hole, the first clamping part 710 abuts against the connecting protrusion 80, preventing the output shaft 631 from moving relative to the connecting protrusion 80. The driving mechanism 60 and the guide plate 30 are connected by clamping, and the connection structure is relatively stable, facilitating the installation and disassembly of the guide plate 30.

[0072] Further, the first clamping part 710 and the second clamping part 720 are obtained by cutting a regular pentagonal prism, the regular pentagonal prism is cut inward along two adjacent prisms, the cut part is U-shaped or V-shaped, the part remaining after cutting has four side walls, which is the first clamping part 710, and the part remaining after cutting has one side wall, which is provided with a protrusion outward to form the second clamping part 720.
