The second driving part 532 is connected to at least one of the mounting seat body 521 and the panel body 1. The output shaft of the second driving part 532 is connected to the mounting seat body 521.

Furthermore, the indoor unit soft wind mode and normal air supply mode can be switched through the first driving unit 531 and the second driving unit 532. That is, when the second driving unit 532 is not running, the first driving unit 531 can drive the air guide plate to move periodically to achieve a flexible air outlet effect for the indoor unit. At the same time, when the first driving unit 531 is driven, the air guide plates can move in parallel with each other, and the air guide surfaces of the multiple air guide plates are highly aligned along the length direction of the air outlet 2. The second driving unit 532 is driven, and the air guide plate assembly and the crankshaft assembly 51 can rotate as a whole to achieve the closed air outlet 2 and the normal air guide mode.

[0060] In an exemplary embodiment, the second driving part 532 is mounted on the panel body 1. The first driving part 531 and the second gear 523 are respectively mounted on the mounting seat body 521, the first driving part 531 is fixedly connected to the first gear 522, and the second gear 523 and the first gear 522 form a gear pair. When the second driving part 532 is not running, the first driving part 531 rotates, and the torque is transmitted to the crankshaft assembly 51 through the first gear 522 and the second gear 523, which can drive the crankshaft assembly 51 to operate continuously. The mounting seat body 521 is mounted on the connecting column 323 to form a hinge structure, and the second driving part 532 is fixedly connected to the mounting seat body 521.

Through the second driving unit 532 and the first driving unit 531, the air conditioner can switch between the soft wind mode and the normal air supply mode.

[0061] The indoor unit has a soft wind mode. When the indoor unit is in the soft wind mode. The first driving unit 531 drives multiple first air guide plates 3 and multiple second air guide plates 4 to enter the second air guiding state. The indoor unit also has a normal air outlet mode. When the indoor unit is in the normal air outlet mode, the second driving unit 532 drives multiple first air guide plates 3 and multiple second air guide plates 4 to enter the first air guiding state. In the soft wind mode, the wave-shaped periodic rhythm of multiple air guide plates can be realized by driving a single first driving unit 531, and the guided airflow flows in different directions, which can effectively break up the original laminar airflow of the air conditioner, achieve an effect similar to natural wind gusts, and avoid direct cold wind. In the normal air supply mode, the indoor unit realizes laminar air outlet of the air conditioner.

[0062] When switching from the soft wind mode to the normal wind mode, the first driving unit 531 first drives the air guiding surfaces of the multiple first air guide plates 3 to be flush with the air guiding surfaces of the multiple second air guide plates 4, then the first driving unit 531 stops operating and the second driving unit 532 starts operating.

[0063] In an optional embodiment, when the air conditioner turns on the soft wind mode or switches from the normal wind guide mode to the soft wind mode, the second drive unit 532 is rotated to control all the air guide plates to rotate to a horizontal state, and then the second drive unit 532 is turned off, and the first drive unit 531 is turned on to drive the air guide plates to cyclically move. When the normal wind guide mode of the air conditioner is turned on, the first drive unit 531 remains in a closed state, and the second drive unit 532 is turned on to drive all the air guide plates to swing up and down. When the air conditioner switches from the soft wind mode to the normal wind guide mode, the first drive unit 531 is rotated to control the air guide plates to be parallel to each other, and then the first drive unit 531 is turned off, and the second drive unit 532 is turned on to drive the air guide plates to swing up and down.

[0064] The technical solution of the present application can also be applied to the technical field of air conditioner equipment. That is, according to another aspect of the present application, an air conditioner is provided, including an indoor unit, and the indoor unit is the indoor unit in the above embodiment.

[0065] According to another aspect of the present application, a control method for an indoor unit is provided, and the method is used to control the indoor unit in the above embodiment, and the method includes the following steps: when the indoor unit switches from the soft wind mode to the normal wind outlet mode, the first driving part 531 is controlled to drive the crankshaft assembly 51 to move, so as to drive the plurality of first air guide plates 3 and the plurality of second air guide plates 4 to rotate to the air guide position; the first driving part 531 is controlled to be closed; the second driving part 532 is controlled to drive the mounting seat assembly 52 to move, so as to drive the plurality of first air guide plates 3 and the plurality of second air guide plates 4 to enter the first air guide state along the air outlet 2. Wherein, when the plurality of first air guide plates 3 and the plurality of second air guide plates 4 are located in the air guide position, the air guide surfaces of the plurality of first air guide plates 3 and the plurality of second air guide plates 4 are arranged flush with each other, and then the first driving part 531 is closed, and the plurality of first air guide plates 3 and the plurality of second air guide plates 4 can be regarded as a large air guide plate as a whole, and then the second driving part 532 is turned on to drive all the air guide plates to swing up and down together, so as to realize the switching of the indoor unit mode.

[0066] The method also includes: when the indoor unit switches from the normal air outlet mode to the soft wind mode, controlling the second drive unit 532 to close; controlling the first drive unit 531 to drive the crankshaft assembly 51 to move, so as to drive multiple first air guide plates 3 and multiple second air guide plates 4 to enter the second air guide state.

[0067] The indoor unit includes two modes: normal air supply mode and soft wind mode. The air supply effect of the normal air supply mode is equivalent to air supply through a single-layer integrated air guide plate. When the indoor unit is in soft wind mode, multiple first air guide plates 3 and multiple second air guide plates 4 can effectively break up the original laminar airflow of the air conditioner, achieving a soft wind effect similar to natural wind gusts. Among them, the soft wind mode and the normal air supply mode are both turned on when the air conditioner is turned off.

[0068] When the air conditioner soft wind mode is turned on or switched from the normal air supply mode to the soft wind mode, the second driving unit 532 is rotated to control all the air guide plates to rotate to a horizontal state. Fig.11 The figure shows that all the air guide plates are rotated to a horizontal state, and then the second driving unit 532 is turned off, and the first driving unit 531 is turned on to drive the air guide plates to oscillate in a wave-like periodic rhythm. In the soft wind mode, the swing angles of adjacent air guide plates are different, and the airflow directions they guide are also different, which can effectively break up the original laminar airflow of the air conditioner, reduce the amount of air blowing on people at a time, and achieve a soft wind effect similar to natural wind gusts, thereby improving the comfort of the air conditioner.

[0069] When the normal wind guide mode of the air conditioner is turned on, the first drive unit 531 remains in a closed state, and the second drive unit 532 is turned on to drive all the air guide plates to swing up and down together. When the air conditioner switches from the soft wind mode to the normal wind guide mode, the first drive unit 531 is rotated to control the air guide plates to be parallel to each other, and then the first drive unit 531 is turned off, and the second drive unit 532 is turned on to drive all the air guide plates to swing up and down together. Among them, the present invention does not limit the number of air guide plates. When the number of air guide plates increases, the airflow dispersion effect of the soft wind mode is better. The technical solution of the application is adopted to effectively solve the discomfort problem caused by the direct blowing of cold air due to the structural limitations of the air guide plates of the existing air conditioners.
