  • the second fan 23 is can be an axial fan, a diagonal fan or a counter-rotating fan.
  • the first fan 22 can be a diagonal fan
  • the second fan 23 can be a counter-rotating fan, which makes for an improved ventilation effect of the indoor unit 100.
  • the diagonal fan adopts the mode of axial air inlet and air outlet inclined at a certain angle along the axial direction for air supply.
  • the air outlet volume of the diagonal fan is relatively large, which not only improves the air outlet volume of first fan 22, but also increases the air outlet angle of first fan 22, thereby expanding the air supply range of the first fan 22.
  • This counter-rotating fan can include two wind wheels mounted on the opposite sides, whose blades are distributed in the opposite directions.
  • the air supply speeds of two wind wheels can be cancelled out in the tangential directions of their rotation directions, while the air supply speeds of two wind wheels can overlap in the axial directions, which can increase the axial air supply speed of the second fan 23, extend the air supply distance of the second fan 23 and enable the second fan 23 to supply air for long distance.
  • the air supply speeds of two wind wheels may overlap in the tangential direction of their rotation directions, and the air supply speeds of two wind wheels can be cancelled out in the axial direction, so that the air can be dispersed all around the second fan 23 and be prevented from being blown directly to the indoor user through the second air outlet 11b, thereby realizing breezeless air outlet effect and improving the use comfort of the user.
  • the counter-rotating fan when only one wind wheel is working, the counter-rotating fan can be used to realize breezeless air outlet effect. Specifically, when one wind wheel of the counter-rotating fans is rotating, another inactive wind wheel also can rotate under the effect of the air flow. At this time, the two wind wheels will rotate in the same direction; according to the above description, the counter-rotating fan also can realize breezeless effect at this moment.
  • the first fan 22 can be turned on when the air supply angle needs to be increased.
  • the first fan 22 can achieve the effect of air supply in a wide range.
  • the second fan 23 can be turned on and the two wind wheels of second fan 23 can be controlled to rotate in the opposite directions, thus improving the air supply distance of second fan 23 greatly.
  • two wind wheels of the second fan 23 can be controlled to rotate in the same direction, so that the second fan 23 can disperse the air all around, preventing the air being blown directly to the indoor users through the second air outlet 11b.
  • the first fan 22 and the second fan 23 are not confined herein.
  • the first fan 22 may be an axial fan, diagonal fan or counter-rotating fan
  • the second fan 23 also may be an axial fan, diagonal fan or counter-rotating fan. It can be used in combination according to the actual use requirements, and there is no specific restriction in this application.
  • the indoor unit 100 can also be composed of the air outlet frame component 21, which can be connected to the housing 1.
  • the air outlet frame component 21 has the first air duct part 24 and the second air outlet part 25 which are distributed at intervals in the up-down direction.
  • the first air duct part 24 is set in alignment with the first air outlet 11a, while the second air duct part 25 is set in alignment with the second air outlet 11b.
  • the first fan 22 is installed in the first air duct part 24, while the second fan 23 is installed in the second air duct part 25.

  • the second door 5 can be equipped with multiple second micro air outlets 5a distributed at intervals.
  • Each second micro air outlet 5a can run through the second door 5 in the thickness direction (front-rear direction as shown in Figure 9 ), which thereby can realize the breezeless air outlet effect and greatly improve users' comfort level.
  • the indoor unit 100 can have the second normal air supply mode and the second breezeless mode.
  • the second driving mechanism 6 can drive the second door 5 to slide relative to the housing 1 to open the second air outlet 11b, through which the air can be discharged.
  • the second door 5 can work with the housing 1 to close the second air outlet 11b, so that the air can be discharged through multiple second micro air outlets 5a.
  • multiple second micro air outlet 5a can divide the air flow into several small branch air flows, and the second micro air outlet 5a with small diameter can slow down the air flow, so that the air can flow out slowly through the second micro air outlet 5a. It thus can realize the breezeless air supply effect, and prevent the air being blown directly to the users, causing discomfort, which improves the user experience significantly.
  • the indoor unit 100 when the indoor unit 100 is in the COOL mode, it can be adjusted to the second breezeless mode to prevent the cool air being blown directly to indoor users, and the cool air can be circulated to the indoor space slowly through multiple second micro air outlets 5a.
  • the indoor unit 100 when the indoor unit 100 is in the HEAT mode, it can be adjusted to the second normal air supply mode since the air density of the warm air is relatively small and the circulation speed is relatively slow, so that the warm air can be circulated quickly into the indoor space through the second air outlet 11b, improving the heating efficiency of the indoor unit 100.
  • multiple third micro air outlets 11c which are distributed at intervals along the periphery of second air outlet 11b, can be installed on the housing 1, and each third micro air outlet 11c can run through the housing 1 in the thickness direction (front-rear direction as shown in Figure 9 ).

  • the second air outlet 11b can be formed into a circle and multiple second micro air outlets 5a can be distributed on the second door 5 at intervals, placed on the opposite direction of the second air outlet 11b.
  • Multiple third micro air outlets 11c which are located at the periphery of second air outlet 11b, are placed at intervals on the housing 1, and are roughly formed into a circle. Therefore, through the above settings, the third micro air outlets 11c on the second door 5 and the third micro air outlets 11c on the housing 1 can discharge air simultaneously, which greatly improves the air outlet efficiency of indoor unit 100, and makes the appearance design of indoor unit 100 more artistic.
