As shown in fig. 2 to 8, the air outlet 44 includes first to fourth air outlet regions 444, and the first to fourth air outlet regions 444 are sequentially disposed along a width direction of the air outlet 44, wherein the width direction of the air outlet 44 is substantially perpendicular to the air outlet direction of the air outlet 44.

The indoor unit 400 further includes a first air deflector 45 and a second air deflector 46.

The first air deflector 45 is disposed in the first air outlet region 441 and/or the second air outlet region 442, which means that the first air deflector 45 is disposed in the first air outlet region 441 or the second air outlet region 442, or disposed at a junction between the first air outlet region 441 and the second air outlet region 442.

The first air deflector 45 is movable relative to the air outlet 44 to adjust the opening sizes of the first and second air outlet regions 441, 442.

The first air deflector 45 may be rotated or slid with respect to the air outlet 44. The first air deflector 45 driving mechanism capable of driving the first air deflector 45 to rotate or slide to adjust the opening sizes of the first air outlet region 441 and the second air outlet region 442 can be applied to the present utility model.

Optionally, a first separator 47 is disposed between the first air outlet area 441 and the second air outlet area 442, and one end of the first air deflector 45 is movably connected with the first separator 47; a second separator 48 is arranged between the third air outlet area 443 and the fourth air outlet area 444, and one end of the second air deflector 46 is movably connected with the second separator 48.

The first air deflector 45 and the second air deflector 46 can move independently of each other, and can also be linked.

Fig. 2 to 8 illustrate various air supply modes, in which the direction of the arrow indicates the flow direction of the air flow.

As shown in fig. 4 and 7, when the first air deflector 45 is at the first position and the second air deflector 46 is at the second position, the opening areas of the first air outlet area 441, the second air outlet area 442, and the fourth air outlet area 444 are all different from zero, and the opening area of the third air outlet area 443 is zero. At this time, the first air outlet area 441, the second air outlet area 442, and the fourth air outlet area 444 have air supply, and the third air outlet area 443 does not have air supply.

Since the third air outlet area 443 does not supply air, the air supply is more biased toward the first air outlet area 441 and the second air outlet area 442 than the third air outlet area 443 and the fourth air outlet area 444, and a partitioned air supply mode biased toward the first air outlet area 441 and the second air outlet area 442 is formed, and is named as a first air supply mode.

And/or, as shown in fig. 8, when the first air deflector 45 is in the third position and the second air deflector 46 is in the fourth position, the opening areas of the first air outlet area 441, the third air outlet area 443, and the fourth air outlet area 444 are all non-zero, and the opening area of the second air outlet area 442 is zero. At this time, the first air outlet area 441, the third air outlet area 443, and the fourth air outlet area 444 have air supply, and the second air outlet area 442 does not have air supply.

Since the second air outlet region 442 does not supply air, the air supply is more biased toward the third air outlet region 443 and the fourth air outlet region 444 than the first air outlet region 441 and the second air outlet region 442, and a partitioned air supply mode biased toward the third air outlet region 443 and the fourth air outlet region 444 is formed, and is named as a second air supply mode.

Alternatively, as shown in fig. 3 and 6, the first air deflector 45 has a first limit position, in which the opening area of the first air outlet area 441 is zero, the first air deflector 45 completely shields the first air outlet area 441, the opening area of the second air outlet area 442 is non-zero, and the second air outlet area 442 is completely opened, and the first air deflector 45 completely avoids the second air outlet area 442.

The limit positions of the first air deflector 45 are a first limit position in which the first air deflector 45 completely shields the first air outlet region 441 and a third position in which the first air deflector 45 completely shields the second air outlet region 442. The first air deflector 45 moves relative to the air outlet 44 between a first extreme position and a third position, the first position being located between the first extreme position and the third position.

As shown in fig. 3 and 6, the second air deflector 46 has a second limit position, in which the opening area of the fourth air outlet area 444 is zero, the second air deflector 46 completely shields the fourth air outlet area 444, the opening area of the third air outlet area 443 is non-zero, and the third air outlet area 443 is completely opened, and the second air deflector 46 completely avoids the third air outlet area 443.

The limit positions of the second air deflector 46 are a second limit position in which the second air deflector 46 completely shields the fourth air outlet area 444 and a second position in which the second air deflector 46 completely shields the third air outlet area 443. The second air deflector 46 moves relative to the air outlet 44 between a second extreme position and a second position, and the fourth position is located between the second extreme position and the second position.

As shown in fig. 2 and 5, when the first air deflector 45 is at the third position and the second air deflector 46 is at the second position, the second air outlet region 442 and the third air outlet region 443 are closed, and the air volumes of the first air outlet region 444 and the fourth air outlet region 444 reach respective maximum values, so as to form an encircling air supply mode, which is named as a third air supply mode.

When the first air deflector 45 is at the first limit position and the second air deflector 46 is at the second limit position, the air volumes of the second air outlet region 442 and the third air outlet region 443 reach respective maximum values, so as to form a fourth air supply mode of middle air supply.

Taking the case that the air outlets are formed by first to fourth air outlet areas, the first to fourth air outlet areas 444 are sequentially arranged along the direction from left to right as an example, in the first air supply mode, an air supply form of a partition at the left side is formed, in the second air supply mode, an air supply form of a partition at the right side is formed, in the third air supply mode, an air supply form of surrounding air supply is formed, and in the fourth air supply mode, an air supply form of middle air outlet is formed.

Alternatively, as shown in fig. 1, the air conditioner is a cabinet air conditioner. The air outlet 44 is provided in a front panel of the casing 50 of the indoor unit 400, and the first to fourth air outlet areas 444 are provided in order in the left-to-right direction.

The first air supply mode realizes the air supply of the left side or the air supply of the left partition, the second air supply mode realizes the air supply of the right side or the air supply of the right partition, the third air supply mode realizes the air supply of the surrounding, and the fourth air supply mode realizes the air supply of the front side.

Optionally, the first air deflector and the second air deflector are both detachably connected to the housing, such as a snap-fit or screw connection.

Alternatively, as shown in fig. 2 to 10, the first air deflector 45 includes a first plate main body 451 and a first grill assembly.

The first plate body 451 moves with respect to the air outlet 44 to adjust the opening sizes of the first and second air outlet regions 441 and 442.

The first grating assembly includes a first grating plate 452, wherein the first grating plate 452 is disposed on one side of the first plate body 451 and spaced apart from the first plate body 451, and a distance between the first grating plate 452 and the first plate body 451 is smaller than a width of the first air outlet region 441 and/or smaller than a width of the second air outlet region 442.

When the opening area of the first air outlet region 441 is not completely zero and the first grating plates 452 are located in the first air outlet region 441, the first grating plates 452 are located in the first air outlet region 441 because the distance between the first grating plates 452 and the first plate body 451 is smaller than the width of the first air outlet region 441. The air flowing through the first air outlet region 441 flows out through the gap between the first grating plates 452 and the first plate body 451, so that the first grating plates 452 and the first plate body 451 together play a role of scattering air flow and preventing direct blowing.

When the opening area of the second air outlet region 442 is not completely zero and the first grating plates 452 are located in the second air outlet region 442, the first grating plates 452 are located in the second air outlet region 442 because the distance between the first grating plates 452 and the first plate body 451 is smaller than the width of the second air outlet region 442. The air flowing through the second air outlet region 442 flows out through the gap between the first grating plates 452 and the first plate body 451, so that the first grating plates 452 and the first plate body 451 together play a role of breaking up the air flow and preventing the direct blowing.

The number of the first grating plates 452 is plural, the plurality of first grating plates 452 are sequentially arranged in a direction away from the first plate main body 451, and when air flows out through a gap between two adjacent first grating plates 452, the gap can break up the air flow, and further direct blowing is prevented.

The plurality of first grating plates 452 may be located on the same side of the first plate body 451 or may be located on different sides.

Optionally, the distance between the first grating plates 452 furthest from the first plate body 451 and the first plate body 451 is smaller than the width of the first air outlet region 441 and/or smaller than the width of the second air outlet region 442, so that all the first grating plates 452 can be located in the same air outlet region (the first air outlet region 441 or the second air outlet region 442) as the first plate body 451, and play a role in breaking up the air flow.

The distance between two adjacent first grating plates 452 increases along the direction in which the air flows through the first air guiding plates 45, so that the air flow flowing through the two adjacent first grating plates 452 can be gently blown out.

It will be appreciated that the distance between adjacent first grating plates 452 may also be constant in the direction of the air flowing through the first air guiding plates 45.

Alternatively, the distance between the first plate body 451 and the first grating plate 452 increases in the direction in which the air flows through the first air guide plate 45, so that the air flow passing between the first plate body 451 and the first grating plate 452 can be gently blown out.

It will be appreciated that the distance between the first plate body 451 and the first grating plate 452 may also be constant in the direction of air flow through the first air deflector 45.

Optionally, the first grating assembly further comprises a second grating plate 453, the second grating plate 453 being located upstream or downstream of the first grating plate 452.

Upstream or downstream refers to upstream through which air flows first and downstream through which air flows later. When the second grating plate 453 is positioned upstream of the first grating plate 452, the air flow passes through the first grating plate 452 after passing through the second grating plate 453. When the second grating plate 453 is positioned downstream of the first grating plate 452, the air flow passes through the second grating plate 453 after passing through the first grating plate 452.

The second grating plates 453 are disposed to be offset from the first grating plates 452, meaning that the orthographic projections of the second grating plates 453 and the first grating plates 452 in a plane perpendicular to the first plate body 451 do not completely coincide.

The second grating plates 453 are provided, and the second grating plates 453 are staggered from the first grating plates 452, so that the scattering effect of the first grating plates 452 and the second grating plates 453 on air is further enhanced.

Optionally, the second air deflector 46 includes a second plate body 461 and a second grid assembly.

The second plate body 461 moves relative to the air outlet 44 to adjust the opening sizes of the third air outlet area 443 and the fourth air outlet area 444; the second grille assembly includes a third grille plate 462, the third grille plate 462 is disposed on one side of the second plate body 461 and spaced apart from the second plate body 461, and a distance between the third grille plate 462 and the second plate body 461 is smaller than a width of the third air outlet area 443 and/or smaller than a width of the fourth air outlet area 444.

When the opening area of the third air outlet area 443 is not completely zero and the third grating plates 462 are located in the third air outlet area 443, the third grating plates 462 are located in the third air outlet area 443 because the distance between the third grating plates 462 and the second plate body 461 is smaller than the width of the third air outlet area 443. The air flowing through the third air outlet area 443 flows out through the gaps between the third grating plates 462 and the second plate bodies 461, so that the third grating plates 462 and the second plate bodies 461 together have the effects of scattering air flow and preventing direct blowing.

When the opening area of the fourth air outlet area 444 is not completely zero and the third grating plates 462 are located in the fourth air outlet area 444, the third grating plates 462 are located in the fourth air outlet area 444 because the distance between the third grating plates 462 and the second plate body 461 is smaller than the width of the fourth air outlet area 444. The air flowing through the fourth air outlet area 444 flows out through the gaps between the third grating plates 462 and the second plate body 461, so that the third grating plates 462 and the second plate body 461 together play a role in breaking up the air flow and preventing direct blowing.

The number of the third grating plates 462 is plural, and the plurality of third grating plates 462 are sequentially arranged in a direction away from the second plate main body 461, and when air flows out through a gap between two adjacent third grating plates 462, the gap can break up the air flow, and further, the air is prevented from being blown straight.

The plurality of third grid plates 462 may be located on the same side of the second plate body 461 or may be located on different sides.

Optionally, the distance between the third grating plate 462 farthest from the second plate body 461 and the second plate body 461 is smaller than the width of the fourth air outlet area 444 and/or smaller than the width of the third air outlet area 443, so that all the third grating plates 462 can be located in the same air outlet area (fourth air outlet area 444 or third air outlet area 443) as the second plate body 461, and play a role in scattering the air flow.

The distance between the adjacent third grating plates 462 increases in the direction in which the air flows through the second air guide plates 46, so that the air flow passing through the adjacent second grating plates 462 can be gently blown out.

It will be appreciated that the distance between adjacent third louvers 462 may also be constant in the direction of air flow through the second air deflector 46.

Alternatively, the distance between the second plate body 461 and the third grid plate 462 increases in the direction in which the air flows through the second air guide plate 46, so that the air flow passing between the second plate body 461 and the third grid plate 462 can be gently blown out.

It will be appreciated that the distance between the second plate body 461 and the third grid plate 462 may also be constant in the direction of air flow through the second air deflector 46.

Optionally, the second grid assembly further comprises a fourth grid plate 463, the fourth grid plate 463 being located upstream or downstream of the third grid plate 462 and being offset from the third grid plate 462.

Upstream or downstream refers to upstream through which air flows first and downstream through which air flows later. When the fourth grid plate 463 is located upstream of the third grid plate 462, the air flow passes through the third grid plate 462 after passing through the fourth grid plate 463. When the fourth grid plate 463 is located downstream of the third grid plate 462, the air flow passes through the fourth grid plate 463 after passing through the third grid plate 462.

The fourth grid plate 463 is disposed offset from the third grid plate 462, meaning that the orthographic projections of the fourth grid plate 463 and the third grid plate 462 in a plane perpendicular to the second plate main body 461 do not completely coincide.

The fourth grating plates 463 are provided, and the fourth grating plates 463 are offset from the third grating plates 462, so that the scattering effect of the third grating plates 462 and the fourth grating plates 463 on the air is further enhanced.

Optionally, when the first air guiding plate 45 is in the third position, the first grating plate 452 assembly is located outside the first plate main body 451, i.e. on the side of the first plate main body 451 away from the middle of the indoor unit 400, so that when the first air guiding plate 45 opens the second air outlet area 442, the first grating plate 452 can be located in the second air outlet area 442; when the second air deflector 46 is in the second position, the second grating plate 453 assembly is located outside the second plate body 461, i.e. on the side of the second plate body 461 away from the middle of the indoor unit 400, so that when the second air deflector 46 opens the third air outlet area 443, the second grating plate 453 can be located in the third air outlet area 443.
