The shape of the first annular air outlet 410 may be circular, rectangular, or the like, and in this embodiment, the first annular air outlet 410 is circular.

Under the action of the fan assembly 300, the airflow is blown out through the first annular air outlet 410.

The indoor unit of an air conditioner further includes a wind direction control assembly 100 provided at an outer side of the panel 400.

With reference to fig. 5 to 7, a second annular air outlet 170 is formed between the outer peripheral edge B of the wind direction control assembly 100 and the outer edge a of the first annular air outlet 410, and the air flow flows out through the first annular air outlet 410 and the second annular air outlet 170 in sequence, so as to realize 360-degree dead-angle-free air supply in the true sense.

Referring to fig. 10, the wind direction control assembly 100 includes a plurality of wind deflectors 110, where the wind deflectors 110 can swing up and down, and specifically, the wind deflectors 110 can swing up and down with respect to a horizontal plane, which defines that the wind deflectors 110 swing up with respect to the horizontal plane when moving clockwise, and the wind deflectors 110 swing down with respect to the horizontal plane when moving counterclockwise.

By the movement of the air deflector 110, the direction of the airflow flowing out from the first annular air outlet 410 through the second annular air outlet 170 can be adjusted, so as to adjust the air supply angle.

The air-conditioning indoor unit in this application has obvious difference at appearance structure at first with traditional indoor unit, and the air outlet is the loop configuration, realizes 360 in the true sense and encircles no dead angle air supply.

First annular air outlet 410 department need not to set up wind-guiding structure, and the regulation of wind direction is realized through wind direction control assembly 100 to realize different air supply modes, improve user and use experience.

In some embodiments of the present application, referring to fig. 3, first annular air outlet 410 is provided with a plurality of grilles 411 arranged at uniform intervals along the circumferential direction, grilles 411 are obliquely arranged, and grilles 411 break up the airflow flowing through first annular air outlet 410, which is favorable for improving the air outlet comfort level.

In some embodiments of the present application, referring to fig. 2 and 5, the fan assembly 300 includes a fan 310, a motor 320, and a fan retainer 330, the motor 320 is fixedly connected to the housing 500 for driving the fan 310, the fan retainer 330 is disposed in the mounting cavity, the fan 310 is located in an area surrounded by the fan retainer 330, and a bottom of the fan retainer 330 is opposite to an outer edge a of the first annular air outlet 410.

Regarding the specific structural design of the wind direction control assembly 100, the present application provides two embodiments, one is that the wind direction control assembly 100 can move up and down relative to the first annular air outlet 410, and the other is that the wind direction control assembly 100 is fixed relative to the first annular air outlet 410.

Example one

In some embodiments of the present application, the indoor unit of an air conditioner further includes a driving portion 200, referring to fig. 3 to 5, one function of the driving portion 200 is to drive the wind direction control assembly 100 to move up and down, so as to adjust the size of the second annular air outlet 170, so as to implement different air supply modes; the driving part 200 is used to indirectly connect the panel 400 and the wind direction control assembly 100, so as to mount the wind direction control assembly 100.

The up-and-down swing of the wind deflector 110 and the up-and-down movement of the wind direction control assembly 100 can be simultaneously or non-simultaneously operated to achieve different blowing modes.

Referring to fig. 5, when the wind direction control assembly 100 is at the highest position, the peripheral edge B of the wind direction control assembly 100 is closer to the outer edge a of the first annular air outlet 410, the second annular air outlet 170 is smaller and closer to the first annular air outlet 410, the airflow flowing out of the first annular air outlet 410 changes in a larger wind direction and then flows out of the second annular air outlet 170, so that the small-angle approximately horizontal air supply is realized, and because the indoor unit of the air conditioner is located at the top of a room, the airflow blown out horizontally descends again, and the cooling-air sedimentation type air supply mode is realized.

The cold air sedimentation type air supply mode can avoid cold air direct blowing users, realize non-wind-sense air supply, and provide relatively uniform and comfortable cooling experience for the users.

In the cold air settling type air supply mode, the air deflector 110 may not move or may move, the air supply angle in the air supply mode may be further adjusted by the movement of the air deflector 100, and the air deflector 110 may swing to adjust the wind direction of the cold air settling type air supply.

Referring to fig. 6, when the wind direction control assembly 100 is at the lowest position, the peripheral edge B of the wind direction control assembly 100 is far away from the peripheral edge a of the first annular air outlet 410, and the second annular air outlet 170 is larger and far away from the first annular air outlet 410, compared with the cold wind sedimentation type air supply mode, the air flow flowing out of the first annular air outlet 410 changes in a smaller wind direction and then flows out of the second annular air outlet 170, so as to realize an approximately vertical downward waterfall type air supply mode.

The waterfall type air supply mode can enhance the blowing body feeling of a user, the blowing is more direct, and the refrigeration and cooling are fast.

In the waterfall type air supply mode, the air deflector 110 may not move or may move, the air supply angle in the air supply mode may be further adjusted by the movement of the air deflector 110, and the wind direction of the waterfall type air supply may be adjusted by the swing of the air deflector 110.

Referring to fig. 7, when the wind direction control assembly 100 moves repeatedly between the lowest position and the highest position, the size of the second annular outlet 170 changes repeatedly, the distance between the second annular outlet 170 and the first annular outlet 410 also changes repeatedly, and the state of the wind blown out from the second annular outlet 170 changes by switching between the cold wind settling type wind blowing mode and the waterfall type wind blowing mode, which is called a forest wind type wind blowing mode.

Under the forest wind type air supply mode, a user seems to be in a forest, feels that a burst of airflow blows to the body, and enjoys the blowing experience closer to natural wind.

In the forest wind type air supply mode, the air deflector 110 can be not moved or can be moved, the air supply angle in the forest wind type air supply mode can be further adjusted through the movement of the air deflector 110, and the wind direction of the forest wind type air supply can be adjusted through the swinging of the air deflector 110.

In some embodiments of the present application, each air deflector 110 swings by an independent driving mechanism, so that in a specific air blowing mode, the swing angle of each air deflector 110 may be the same or different, and when the swing angles of the air deflectors 110 are different, different air blowing angles can be obtained in different directions, thereby further meeting different air blowing requirements of users.
