The air conditioner indoor unit in this application is the air conditioner indoor unit of the omnidirectional air-out of a kind of top formula.

Referring to fig. 1 and 2, the air conditioning indoor unit includes a casing 500, and the casing 500 constitutes an outer contour of the indoor unit, and has a mounting cavity formed therein for mounting components such as a fan assembly and a heat exchanger.

The bottom of the housing 500 is open, a panel 400 is fixedly arranged at the open, and a first annular air outlet 410 is arranged on the panel 400.

Referring to fig. 4, 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 that 360-degree air supply around no dead angle is realized in a true sense.

Referring to fig. 10, 11 and 14, the wind direction control assembly 100 includes a plurality of wind deflectors 110, and the wind deflectors 110 can extend or retract from the wind direction control assembly 100 along a horizontal direction, and can adjust the size of the second annular outlet 170, so as to adjust the direction of the airflow flowing out from the first annular outlet 410 through the second annular outlet 170. The plurality of air deflection panels 110 are shown in a retracted state in fig. 10 and the plurality of air deflection panels 110 are shown in an extended state in fig. 14.

Through the extension and retraction of the air deflector 110, the size of the second annular air outlet 170 can be adjusted, and the direction of the airflow flowing out from the first annular air outlet 410 through the second annular air outlet 170 is adjusted, so that the air supply angle is adjusted.

The air deflector 110 extends out, the outer peripheral edge of the whole wind direction control assembly 100 is enlarged, and the second annular air outlet 170 is reduced; the air deflector 110 retracts, the entire outer peripheral edge of the wind direction control assembly 100 is reduced, and the second annular air outlet 170 is enlarged.

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, when the air deflectors 110 extend out, at least a portion of the adjacent two air deflectors 110 is overlapped up and down, referring to fig. 3 and 14, the air deflectors 110 form an annular air guiding structure at the second annular air outlet 170, so as to prevent a gap from being formed between the adjacent two air deflectors 110 to affect the air guiding effect.

In some embodiments of the present application, referring to fig. 7, first annular air outlet 410 is provided with a plurality of grilles 411 that are uniformly spaced along its circumference, and grilles 411 are obliquely disposed, and grilles 411 break up the air current that flows through first annular air outlet 410, and are favorable to improving the air-out comfort level.

In some embodiments of the present application, referring to fig. 2 and 4, 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 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. 4, 7 to 9, 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, and 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 extension and retraction of the air deflection plates 110 may be performed simultaneously or simultaneously with the up and down movement of the wind direction control assembly 100 to achieve different blowing modes.

Referring to fig. 4, 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 can be not moved or moved, and the air direction of the cold air settling type air supply can be further adjusted through the extension of the air deflector 110.

Referring to fig. 5, 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, and the wind direction of the waterfall type air supply may be further adjusted by the extension of the air deflector 110.

Referring to fig. 6, when the wind direction control assembly 100 moves repeatedly between the lowest position and the highest position, the size of the second annular air outlet 170 changes repeatedly, the distance between the second annular air outlet 170 and the first annular air outlet 410 also changes repeatedly, and the state of the wind blown out from the second annular air outlet 170 changes by switching between the cold wind sedimentation type wind supply and the waterfall type wind supply, which is called a forest wind type wind supply 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 mode of forest wind type air supply, the air deflector 110 can be not moved or moved, and the wind direction of forest wind type air supply can be further adjusted by extending the air deflector 110 out.

In some embodiments of the present application, referring to fig. 7, a mounting portion 420 is disposed on the panel 400, the first annular air outlet 410 is disposed around an outer circumference of the mounting portion 420, and the mounting portion 420 is used for mounting the wind direction control assembly 100 and the driving portion 200.

Referring to fig. 20, the air deflector 110 is provided with a first guide protrusion 111 and a second guide protrusion 112, the first guide protrusion 111 is slidably disposed in the linear guide slideway 121, and the second guide protrusion 112 is slidably disposed in the arc-shaped drive slideway 181.

The first driving motor 160 drives the driving disc 180 to rotate, and the arc driving slideway 181 applies force to the second guiding protrusion 112, so that the guiding plate 110 has a rotating movement tendency, but because the first guiding protrusion 111 is limited in the linear guiding slideway 121, the guiding plate 110 cannot rotate, but moves along the linear guiding slideway 121, thereby realizing the extending and retracting actions of the guiding plate 110.

In some embodiments of the present application, referring to fig. 12 and 16, a cylindrical shaft 140 is disposed on the stationary disk 120, the cylindrical shaft 140 extends upward from the center of the stationary disk 120, and a first hollow cavity 143 with an open top is disposed in the cylindrical shaft 140.

The "outer peripheral edge of the wind direction control assembly" mentioned above is actually the outer peripheral edge of the wind guiding ring 130.

The guide plate 110 extends out, which means that the guide plate 110 extends out and exposes relative to the outer peripheral edge of the air guide ring 130; the guide plate 110 is retracted, which means that the guide plate 110 is retracted from the outer peripheral edge of the wind-guiding ring 130.
