[0102] In the switching process from the intermediate air supply mode to the closed mode of the air conditioner indoor unit, taking the left driving assembly 40, the inner air guiding assembly 30 and the outer air guiding assembly 20 as an example, the driving part 47 drives the common gear 4212 to rotate counterclockwise, so that the first gear drives the first transmission plate 4214 to move rightward along the first sliding rail 441, the rod part 4211 on the first transmission plate 4214 moves to the right end of the groove part 4221 of the second transmission plate 4222, and drives the second transmission plate 4222 to move rightward. In this process, the common gear 4212 also synchronously drives the inner air guiding assembly 30 to rotate clockwise through the gear set 411. When the second transmission plate 4222 drives the outer air guiding assembly 20 to move from the second position to the first position, the inner air guiding assembly 30 rotates to the position closing the outlet of the air duct part 60, and the air conditioner indoor unit is switched to the closed mode, so as to realize the switching of the air conditioner indoor unit to the closed mode by synchronously driving the inner air guiding assembly 30 and the outer air guiding assembly 20 through one driving part 47.

[0104] The switching process of the air conditioner indoor unit from the closed mode to the double-flow air supply mode will be described in detail below with reference to Figure 2 and Figure 14 .

[0105] In the switching process from the closed mode to the double-flow air supply mode of the air conditioner indoor unit, taking the left driving assembly 40, the inner air guiding assembly 30 and the outer air guiding assembly 20 as an example, the driving part 47 drives the common gear 4212 to rotate clockwise, so that the first gear drives the first transmission plate 4214 to move leftward along the first sliding rail 441, the rod part 4211 on the first transmission plate 4214 moves from the right end to the left end of the groove part 4221 of the second transmission plate 4222, and the second transmission plate 4222 and the outer air guiding assembly 20 are not moved. In this process, the common gear 4212 also drives the inner air guiding assembly 30 to rotate counterclockwise through the gear set 411, so as to rotate the inner air guiding assembly 30 to open the outlet of the air duct part 60, and the air guiding direction of the inner air guiding assembly 30 is towards the left sub-air outlet, thereby realizing the switching of the air conditioner indoor unit from the closed mode to the double-flow air supply mode by separately adjusting the rotation angle of the inner air guiding assembly 30 without changing the position of the outer air guiding assembly 20 through one driving part 47.

[0106] It should be noted that in the switching process from the closed mode to the double-flow air supply mode of the air conditioner indoor unit, the rod part 4211 on the first transmission plate 4214 slides in the groove part 4221 of the second transmission plate 4222, and does not drive the second transmission plate 4222 to move.

[0107] The switching process of the air conditioner indoor unit from the closed mode to the double-flow air supply mode will be described in detail below with reference to Figure 2 ,Figure 10 and Figure 15 The switching process of the air conditioner indoor unit from the closed mode to the intermediate air supply mode is described in detail.

[0112] According to another aspect of the embodiment of the present application, the air conditioner comprises the above-mentioned air conditioner indoor unit.

[0113] According to the air conditioner of the embodiment of the present application, the air conditioner indoor unit comprises: a casing 10, an outer air guiding assembly 20, an inner air guiding assembly 30 and a driving assembly 40. The outer air guiding assembly 20 is movably arranged on the casing 10. The outer air guiding assembly 20 can be arranged at the air outlet of the casing 10. The opening direction of the air outlet can be adjusted by the movement of the outer air guiding assembly 20. The outer air guiding assembly 20 can be an air guiding panel. The air guiding panel can be used as a switch door of the air outlet of the air conditioner indoor unit. The air guiding function can be realized by moving the air guiding panel. The outer side of the outer air guiding assembly 20 can be flush with the display panel 111 to improve the appearance of the air conditioner indoor unit. The inner side of the outer air guiding assembly 20 has a guide surface 21. The guide surface 21 can be a curved surface or an inclined surface to guide the airflow at the outlet of the air duct component 60 to the air outlet. The inner air guiding assembly 30 is movably arranged on the casing 10. The inner air guiding assembly 30 is arranged at the inner side of the outer air guiding assembly 20. That is, the inner air guiding assembly 30 is located upstream of the outer air guiding assembly 20 in the air outlet path of the air conditioner indoor unit. The inner air guiding assembly 30 can be arranged at the outlet of the air duct component 60.

[0114] The driving assembly 40 is in driving cooperation with the outer air guiding assembly 20. The outer air guiding assembly 20 can move relative to the casing 10 between a first position and a second position. The movement mode of the outer air guiding assembly 20 can be moving. The driving assembly 40 can drive the left-right movement of the outer air guiding assembly 20 to change the position of the outer air guiding assembly 20 at the air outlet, thereby adjusting the opening direction of the air outlet to control the overall air outlet direction of the air conditioner indoor unit. The driving assembly 40 is also in driving cooperation with the inner air guiding assembly 30. The driving assembly 40 can drive the inner air guiding assembly 30 to rotate to adjust the air outlet direction in the left-right direction.

[0115] It should be noted that when the outer air guiding assembly 20 moves between the first position and the second position, the driving assembly 40, the outer air guiding assembly 20 and the inner air guiding assembly 30 are synchronously linked to synchronously drive the inner air guiding assembly 30 and the outer air guiding assembly 20 by the driving assembly 40. When the outer air guiding assembly 20 moves to the first position or the second position, the outer air guiding assembly 20 can be disconnected from the linkage with the inner air guiding assembly 30. The driving assembly 40 can drive the inner air guiding assembly 30 to move within a preset range to guide the air. When the outer air guiding assembly 20 moves to any position between the first position and the second position, the outer air guiding assembly 20 can be disconnected from the linkage with the driving assembly 40 and the inner air guiding assembly 30.

The driving assembly 40 and the outer air guide assembly 20 can form an intermittent movement mechanism. When the driving assembly 40 drives the outer air guide assembly 20 to be in a movement state, the driving assembly 40 simultaneously drives the inner air guide assembly 30 and the outer air guide assembly 20 to move synchronously. At this time, if the driving direction of the driving assembly 40 is changed, the outer air guide assembly 20 can be disconnected from the driving assembly 40 to realize that the driving assembly 40 drives the inner air guide assembly 30 to move in a preset range alone. The preset range can be a rotation angle interval of the inner air guide assembly 30 driven by the driving assembly 40 alone. For example, the preset range can be 0°~45°.

[0117] According to the air conditioner provided by the embodiment of the present application, the driving assembly 40 can drive the inner air guide assembly 30 and the outer air guide assembly 20 to move synchronously, and the driving assembly 40 can also drive the inner air guide assembly 30 to move in a preset range alone. Therefore, the number of the driving assembly 40 and the related matching components of the air conditioner indoor unit can be reduced under the condition that the control function of the air conditioner indoor unit on the inner air guide assembly 30 and the outer air guide assembly 20 is maintained, so that the structure of the air conditioner indoor unit is compact, and the cost of the air conditioner indoor unit is reduced.
