[0051] Figure 1 is a schematic structural diagram of closing the air outlet according to an embodiment of the present application,Figure 1 As shown in the accompanying drawings and described Figures 2 to 8 The utility model discloses an air -conditioning indoor unit 100, including casing 10, guide plate subassembly and connecting rod 430, be equipped with air outlet 20 on casing 10. Guide plate subassembly includes push rod 440 and sets up at the front end of push rod 440's guide plate 30, and guide plate 30 is at the position of closing air outlet 20, and push rod 440 is telescopically arranged on casing 10. Connecting rod 430 rotatably installed on casing 10, and connecting rod 430 is straight plate shape. Connecting rod 430 includes first extrusion surface 451 and second extrusion surface 452, and when connecting rod 430 rotates to the first direction, first extrusion surface 451 and push rod 440 extrusion drive push rod 440 to extend. When connecting rod 430 rotates to the second direction opposite the first direction, second extrusion surface 452 and push rod 440 extrusion drive push rod 440 to retract.

[0052] In the embodiment, when connecting rod 430 rotates to the first direction, because of the extrusion of first extrusion surface 451 and 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, thereby making guide plate 30 open air outlet 20. When connecting rod 430 rotates to the second direction, because of the extrusion of second extrusion surface 452 and 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, thereby making guide plate 30 close air outlet 20. Pushing guide plate 30 out of air outlet 20 through connecting rod 430 and push rod 440 avoids the situation that guide plate 30 shields air outlet 20, thereby reducing the situation that heat exchange air blows to guide plate 30, making heat exchange air outflow more smoothly, preventing guide plate 30 from affecting the outflow angle and the outflow amount of air, and improving the air outflow effect of air -conditioning indoor unit 100. Moreover, pushing guide plate 30 out of air outlet 20 reduces the obstruction of guide plate 30 to air outflow, thereby reducing the noise generated by heat exchange air blowing to guide plate 30.

[0053] In some other embodiments of the utility model, one connecting rod 430 and one push rod 440 form a group, and the connecting rod 430 and the push rod 440 can form one group or multiple groups. When multiple groups are arranged, multiple push rods 440 are respectively connected to different parts of guide plate 30 and simultaneously act to drive guide plate 30 to translate, so that the movement of guide plate 30 is more stable, especially for long strip-shaped guide plate 30. In addition, when multiple groups are arranged, only one group can drive guide plate 30 to move, and each group does not need to have the function of driving guide plate 30 to move.

[0054] Further, in some embodiments of the utility model, as shown in the accompanying drawings, Figure 1 The guide plate 30 is a long strip extending in the transverse direction, and the connecting rod 430 and the push rod 440 are respectively provided with two, and the two push rods 440 are respectively connected to the transverse ends of the guide plate 30, that is, the two ends of the guide plate 30 in the length direction.

[0055] In some embodiments of the present application, as shown in Figure 2 The push rod 440 has a sliding block on one side close to the connecting rod 430. The connecting rod 430 has a sliding channel 450 therein, which extends along the length direction of the connecting rod 430, and two oppositely arranged side walls of the sliding channel 450 are a first extrusion surface 451 and a second extrusion surface 452 respectively.

[0056] In the present embodiment, the connecting rod 430 has the sliding channel 450 therein, and the sliding block slides in the sliding channel 450 to drive the push rod 440 to extend or retract. When the connecting rod 430 rotates to a first direction, the first extrusion surface 451 extrudes the sliding block, and the sliding block slides along the first extrusion surface 451, so that the push rod 440 is pushed to the direction close to 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 to a second direction, the second extrusion surface 452 extrudes the sliding block, and the sliding block slides along the second extrusion surface 452, so that the push rod 440 is retracted to the direction away from the front end of the push rod 440, thereby causing the guide plate 30 to close the air outlet 20. The connecting structure between the connecting rod 430 and the push rod 440 is simple, the transmission is stable, and the moving process of the guide plate 30 is relatively stable.

[0057] In some other embodiments of the present application, the push rod 440 has a sliding block on one side close to the connecting rod 430. The connecting rod 430 has a sliding groove therein, and the opening of the sliding groove faces the push rod 440. The sliding block is slidable and rotatable in the sliding groove. Two oppositely arranged groove walls of the sliding groove are a first extrusion surface and a second extrusion surface respectively.

[0058] In some embodiments of the present application, as shown in Figure 3 and Figure 4 The push rod 440 includes a first housing 441, a second housing 442 and a containing cavity 443. The first housing 441 and the second housing 442 are combined. The containing cavity 443 is formed by the combined first housing 441 and second housing 442.

[0059] In some embodiments of the present application, as shown in Figure 1 The air conditioner indoor unit 100 further includes at least one driving mechanism 60, which is arranged in the containing cavity 443 and is used to drive the guide plate 30 to rotate. The driving mechanism includes a motor 610, a first gear 620 and a second gear 630, which are installed at the front end of the containing cavity 443. 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 first housing 441 or the second housing 442, and the output shaft 631 is connected with the guide plate 30 to drive the guide plate 30 to rotate by the motor 610.

[0060] In the embodiment, the air conditioner indoor unit 100 further comprises at least one driving mechanism 60, which is arranged in the accommodating cavity 443. When the push rod 440 pushes the guide plate 30 out of the air outlet 20, the driving mechanism 60 operates to rotate the guide plate up and down. When the driving mechanism 60 operates, 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 rotates to a horizontal position or an upward angle, the heat exchange air is blown out from the air outlet 20, and the guide plate 30 does not affect the blowing out of the heat exchange air, avoiding the guide plate 30 from affecting the air outlet amount of the heat exchange air. The guide plate 30 also 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.

[0061] Further, the driving mechanism 60 is arranged in the accommodating cavity 443, which prevents dust from falling on the driving mechanism 60, and avoids the dust from affecting the meshing transmission between the first gear 620 and the second gear 630, thereby prolonging the service life of the driving mechanism 60.

When the push rod 440 is multiple, one push rod 440 is arranged with the driving mechanism 60. Alternatively, part of the push rod 440 or the push rod 440 is arranged with the driving mechanism 60.

[0063] Further, in some embodiments of the utility model, the push rod 440 is arranged two, one of which is arranged with the driving mechanism 60, thereby saving the production and operation cost of the air conditioner indoor unit 100, and simplifying the control of the guide plate 30.

[0065] In the embodiment, the guide plate 30 is formed with the accommodating groove 50. The driving mechanism 60 is arranged in the accommodating cavity 443 of the push rod 440, so that the end of the push rod 440 close to the guide plate 30 has a large volume. When the guide plate 30 rotates, the accommodating cavity 443 may block the rotation of the guide plate 30. By arranging the accommodating groove 50 on the guide plate 30, part of the accommodating cavity 443 is arranged in the accommodating groove 50 when the guide plate 30 rotates, thereby facilitating the rotation of the guide plate 30.

[0066] In some embodiments of the utility model, as shown in Figure 3 And Figure 4As shown, the end surface of the output shaft 631 is provided with a first clamping part 710, and the outer side wall of the first clamping part 710 has at least one plane, and the inner side of the guide plate 30 is provided with a connecting protrusion 80, and the connecting protrusion 80 is provided with a connecting hole, and the first clamping part 710 is installed in the connecting hole, and the side surface of the connecting hole is matched with the outer side profile of the first clamping part 710.

[0067] In the embodiment, the driving mechanism 60 is clamped with the connecting protrusion 80 of the guide plate 30 through the first clamping part 710. 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, so that the relative rotation of the first clamping part 710 and the connecting protrusion 80 is prevented, and the rotation of the first clamping part 710 can drive the rotation of the guide plate 30.

[0068] In some embodiments of the utility model, as shown in Figure 3 and Figure 4 As shown, the end surface of the output shaft 631 is further provided with a second clamping part 720, and the second clamping part 720 comprises at least one clamping claw 721, and the clamping claw 721 protrudes away from the first clamping part 710.

[0069] In the embodiment, the driving mechanism 60 is clamped with the connecting protrusion 80 of the guide plate 30 through the second clamping part 720. The upper end of the second clamping part 720 has the clamping claw 721, and after the second clamping part 720 penetrates into the connecting hole, the clamping claw 721 abuts against the connecting protrusion 80, so that the relative movement of the output shaft 631 and the connecting protrusion 80 is prevented. The driving mechanism 60 and the guide plate 30 are connected in a clamping mode, the connecting structure is relatively stable, and the installation and dismounting of the guide plate 30 are facilitated.

[0072] In the embodiment, the rear side of the air outlet 20 is provided with a baffle 120, and the guide plate 30 abuts against the baffle 120 when the guide plate 30 closes the air outlet 20, so that the front surface of the guide plate 30 is flush with the front surface of the shell 10, and the appearance of the air conditioner indoor unit 100 is more complete and beautiful. The baffle 120 is provided with a giving slot 130, and the connecting protrusion 80 or the driving mechanism 60 is located in the giving slot 130 or the giving hole when the guide plate 30 closes the air outlet 20.

[0073] In some embodiments of the utility model, as shown in Figure 5 The air outlet 20 penetrates through the transverse two side surfaces of the shell 10, so that the front surface of the guide plate 30 is flush with the front surface of the shell 10 when the guide plate 30 is in the position of closing the air outlet 20.

[0074] In the embodiment, the air outlet 20 penetrates through the transverse two side surfaces of the shell 10, and the transverse two end surfaces of the guide plate 30 are not restricted and blocked by the shell 10, so that even if the push rod 440 is slightly displaced, the shell 10 will not interfere, and the guide plate 30 can always be smoothly expanded and contracted, and is not prone to failure such as jamming and locking. When the guide plate 30 closes the air outlet 20, 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.

The outer frame 112 is further provided with an air inlet, and the air inlet is above the air outlet 20. The air inlet grille 111 is detachably arranged at the air inlet.

[0078] In the embodiment, the front plate 110 is composed of an outer frame 112 and an air inlet grille 111 mounted on the outer frame 112, and the air inlet grille 111 is detachably connected with the outer frame 112, so that the air inlet grille 111 can be conveniently mounted and detached.

[0079] In some embodiments of the utility model, as shown in Figure 5 The air inlet and the air outlet 20 have a spacing therebetween. After the push rod 440 is fully extended, the upper side of the guide plate 30 is located at the spacing.

[0080] In the embodiment, when the guide plate 30 is opened, the guide plate 30 moves upward to the limit position, and the upper side of the guide plate 30 is located at the spacing. Due to the blocking of the guide plate 30, the air inlet flow and the air outlet flow are not easily mixed, and the air outlet flow is prevented from entering the air conditioner indoor unit 100 from the air inlet, or the air inlet flow and the air outlet flow are prevented from being mixed and directly blown into the room. Therefore, the spacing between the air outlet 20 and the air inlet can be designed to be as small as possible, so that the air inlet and the air outlet 20 can be designed to be larger, and the air inlet area and the air outlet area can be increased as much as possible, thereby solving the problem of low air conditioner efficiency caused by insufficient air inlet and insufficient air outlet.

[0081] In some embodiments of the utility model, the outer frame 112 is detachably mounted on other parts of the shell 10.

[0082] In the embodiment, the outer frame 112 is detachably mounted on other parts of the shell 10, so that the outer frame 112 can be conveniently mounted and detached. When the internal components of the air conditioner indoor unit 100 are damaged and need to be repaired, the outer frame 112 can be detached, and the internal components can be repaired or replaced from the front side without the need to detach the air conditioner indoor unit 100 from the cabinet, thereby reducing the difficulty of repair or replacement and facilitating the repair and replacement of the internal components of the air conditioner indoor unit 100.

[0083] In some embodiments of the utility model, as shown in Figure 5 The shell 10 includes 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 rear to front.

[0084] In the embodiment, the through hole gradually inclines upward from rear to front, and 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.
