[0086] In the embodiment, the air outlet 20 penetrates through the lateral two sides of the shell 10, and the lateral two end surfaces of the guide plate 30 are not restricted and blocked by the shell 10. Even when the push rod 440 and the push rod 440 are slightly displaced, the guide plate 30 is not interfered by the shell 10, and 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.

[0087] In some embodiments of the utility model, as shown in Figure 1 the rear side of the air outlet 20 has a baffle 120 at two ends, and the baffle 120 abuts against the guide plate 30 when the guide plate 30 is in the position of closing the air outlet 20. The baffle 120 is provided with a gap slot 130.

[0088] In the embodiment, the rear side of the air outlet 20 has the 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 the gap slot 130, and the connecting protrusion 80 and the push rod 440 are in the gap slot 130 when the guide plate 30 closes the air outlet 20.

[0089] In some embodiments of the present application, as shown in Figure 7 The shell 10 further comprises a front plate 110 constituting a front structure of the shell 10, and the front plate 110 is arranged towards the front. The front plate 110 comprises an outer frame 112 and an air inlet grille 111, and the air outlet 20 is arranged on the outer frame 112, and an air inlet is further formed on the outer frame 112, and the air inlet is above the air outlet 20. The outer frame 112 is detachably mounted on other parts of the shell 10. The air inlet grille 111 is detachably mounted at the air inlet.

[0090] In the present embodiment, the outer frame 112 is detachably mounted with other parts of the shell 10, facilitating the mounting and dismounting of the outer frame 112. When there is a component inside the air conditioner indoor unit 100 that needs to be repaired, the outer frame 112 can be dismounted, and the internal components can be repaired or replaced from the front side, without the need to dismount the air conditioner indoor unit 100 from the cabinet, reducing the difficulty of repair or replacement, and facilitating the repair and replacement of the internal components of the air conditioner indoor unit 100.

[0091] In some embodiments of the present application, as shown in Figure 7 There is a gap between the air inlet and the air outlet 20. After the push rod 440 is fully extended, the upper side of the guide plate 30 is at the gap.

[0092] In the present embodiment, the front plate 110 further comprises an air inlet, and the air inlet is above the air outlet 20. When the guide plate 30 opens the air outlet 20, the guide plate 30 moves upwards to the limit position, and the upper side of the guide plate 30 is at the gap. Due to the blocking of the guide plate 30, the outflow and the inflow are not easily mixed, avoiding the outflow from the air inlet into the air conditioner indoor unit 100, or avoiding the inflow and the outflow from being mixed and directly blown into the room. Therefore, the distance between the air outlet 20 and the air inlet can be designed as small as possible, so as to design the air inlet and the air outlet 20 larger, and increase the air inlet area and the air outlet area as much as possible, thereby solving the problem of low air conditioner efficiency caused by insufficient air inlet and air outlet.

The first connecting block 911 is arranged at the rear side of the air inlet grille 111, and the end of the first connecting block 911 has a first clamping block 912 protruding downwards. The second connecting block 913 is arranged at the rear side of the outer frame 112, and the second connecting block 913 has a second clamping block 914 protruding upwards, and the upper side of the second connecting block 913 is provided with a through hole allowing the first connecting block 911 to pass through.

[0094] In the embodiment, the rear side of the air inlet grille 111 is provided with a vertical first connecting block 911, and the rear side of the outer frame 112 is provided with a vertical second connecting block 913. When the air inlet grille 111 is installed at the air inlet position, the first connecting block 911 passes through the through hole, and when the air inlet grille 111 is attached to the outer frame 112, the first clamping block 912 abuts against the second clamping block 914, so that the air inlet grille 111 and the outer frame 112 are installed. The first connecting part 910 is simple in structure, low in production cost, and convenient for installation and disassembly of the air inlet grille 111 and the outer frame 112, and the connection of the air inlet grille 111 and the outer frame 112 is stable.

[0095] In some embodiments of the utility model, as shown in Figure 8 and Figure 10 The air conditioner indoor unit 100 further includes a second connecting part 920, the second connecting part 920 includes a mounting hole, a mounting groove 922 and a third connecting block 923, the mounting hole and the mounting groove 922 are formed on the outer frame 112, the mounting groove 922 opens towards the rear side, and the mounting groove 922 is below the mounting hole and communicates with the mounting hole. The third connecting block 923 is V-shaped and opens towards the air inlet grille 111, the third connecting block 923 passes through the mounting hole, the upper end of the third connecting block 923 is connected to the air inlet grille 111, and the lower end of the third connecting block 923 extends to form a mounting column 924, the mounting column 924 is perpendicular to the third connecting block 923, and the mounting column 924 is perpendicularly and rotatably installed on the side wall of the mounting groove 922.

[0096] In the embodiment, the rear side of the air inlet grille 111 is connected with a V-shaped third connecting block 923, the third connecting block 923 passes through the mounting hole, one end of the third connecting block 923 is fixedly connected to the air inlet grille 111, and the other end of the third connecting block 923 is rotatably connected to the outer frame 112. When the air inlet grille 111 is installed, the third connecting block 923 passes through the mounting hole, and the mounting column 924 is inserted into the hole in the side wall of the mounting groove 922. The second connecting part 920 enables the air inlet grille 111 to be installed and rotated, that is, the air inlet grille 111 can be rotated downward without being detached from the outer frame 112, thereby further facilitating replacement and maintenance of internal components of the air conditioner indoor unit 100.

[0097] In some embodiments of the utility model, the air conditioner indoor unit 100 is an embedded air conditioner indoor unit, a wall-mounted air conditioner indoor unit, a stand-type air conditioner indoor unit or other types of air conditioner indoor units. Preferably, the air conditioner indoor unit 100 is an embedded air conditioner indoor unit.

[0098] Up to now, the person skilled in the art should recognize that, although the multiple exemplary embodiments of the utility model have been shown and described in detail herein, many other variants or modifications conforming to the principles of the utility model can still be directly determined or deduced according to the content disclosed by the utility model without departing from the spirit and scope of the utility model. Therefore, the scope of the utility model should be understood and recognized as covering all these other variants or modifications.
