Fig. 1 to 8 are schematic structural diagrams of eight air outlet modes of an indoor unit of an air conditioner according to an embodiment of the present invention; fig. 9 is a schematic structural view of a first air outlet portion of an indoor unit of an air conditioner according to an embodiment of the present invention.

As shown in fig. 1, an embodiment of the present invention provides an indoor unit of an air conditioner. The indoor unit of an air conditioner includes a casing 10, and a first air outlet portion and a second air outlet portion which are symmetrically disposed about a vertical plane extending in the front-rear direction. The first air outlet portion includes a first air outlet and an air outlet duct 22. The first air outlet is disposed in front of one sidewall of the housing 10. The air outlet duct 22 is disposed in the casing 10 and is communicated with the first air outlet to deliver air flow to the first air outlet. During operation, the two air outlet channels 22 can supply air to the two first air outlets, so that surrounding air supply is realized. The surrounding air supply can prevent cold air from blowing directly, and is different from a conventional air supply mode, so that comfortable air supply experience is provided for users.

In some preferred embodiments, the first outlet vent includes a plurality of slits 30 arranged in series in the front-rear direction, and each slit 30 extends obliquely forward from an inner end thereof to an outer end thereof. Because first air outlet has a plurality of special gaps 30, can realize embracing the air supply and for gentle breeze, form embracing gentle breeze mode promptly, make the user more comfortable. In the surrounding soft wind mode, the air-conditioning wind blows out from the wind outlet duct 22, and finally blows out from the air outlets at two sides of the indoor unit of the air conditioner through the diversion effect of the vertical swing blades 70, so that the air-conditioning wind respectively blows towards two sides at a larger angle. From the aerodynamic perspective, the air flow on the two sides can form two backflow areas in the middle area, and the body can feel comfortable and soft cold air and can avoid the direct blowing of cold air. Further, the arrangement and combination of the plurality of slits 30 can make the side wall of the housing 10 more beautiful, and the inclined slits 30 also have a dust-proof effect.

Preferably, as shown in fig. 9, the slit 30 is linear, and the angle between the slit 30 and a vertical plane extending in the transverse direction is 25 ° to 35 °. The width of the gap 30 is 1.5mm to 2.5mm, preferably 2 mm. The number of slits 30 is 12 to 14. In some other embodiments, the slot 30 is curved, with the inner end of the slot 30 corresponding in size to the outer end opening, or the slot 30 may be open with a smaller outer end and a larger inner end.

In some embodiments, the first air outlet portion further includes a second air outlet 23, and the second air outlet 23 is disposed at an end of the front wall of the housing 10 close to the first air outlet. The air outlet duct 22 is also communicated with the second air outlet 23 to deliver air flow to the second air outlet 23. The second outlet 23 is provided so that the air conditioner can blow the conditioned air not only to the side front but also to the front.

In some embodiments, the first air outlet portion further includes a plurality of vertical swing blades 70 sequentially disposed at the outlet of the air outlet duct 22 along the width direction of the air outlet duct 22, and each vertical swing blade 70 is rotatably disposed around a vertical axis. Each of the flaps 70 extends in the vertical direction and has a curved shape that is arched toward the outside in the closed state. The plurality of vertical swing blades 70 block the air outlet duct 22 in a closed state. The vertical swing blade 70 mainly functions to guide and block the air outlet duct 22. For example, when the air conditioner is in the soft wind mode, the flaps 70 are controlled to rotate to the corresponding positions to direct the air flow to blow toward the first outlet. When the air conditioner is in the non-soft wind mode, the vertical swing blade 70 is controlled to rotate to the corresponding position to guide the air flow to be blown to the second air outlet 23. When the air conditioner is in a closed state or one of the first air outlet portion and the second air outlet portion does not need to blow air, the corresponding plurality of vertical swing blades 70 are bent and arched towards the outer side, and the corresponding air outlet duct 22 is blocked, so that the corresponding first air outlet and the corresponding second air outlet 23 are not blown by air.

By adjusting the opening or closing state of the first air outlet and the second air outlet 23 and adjusting the vertical swing blade 70, the air conditioner is in different air supply modes to meet different requirements of users.

Specifically, as shown in fig. 9, the first air outlet portion further includes a sliding plate 24 and a driving device. The sliding plate 24 has a first position for blocking the first air outlet and a second position for blocking the second air outlet 23, that is, the sliding plate 24 can be moved to the first position to block the first air outlet and also moved to the second position to block the second air outlet 23. The drive arrangement is configured to transition the slide plate 24 between the first and second positions. The opening or closing state of the first air outlet and the second air outlet 23 is adjusted by controlling the position of the sliding plate 24, so that the air conditioner is in different air supply modes.

For example, as shown in fig. 1, when the air conditioner is in a closed state, i.e., in an initial state, the sliding plate 24 blocks the second air outlet 23, and the air outlet duct 22 is in a blocked state. At this time, neither the first outlet port nor the second outlet port 23 is blown by wind.

As shown in fig. 2, when the air conditioner is in the front blowing mode, the sliding plate 24 blocks the first air outlet, the second air outlet 23 is in the open state, the vertical swing blade 70 is adjusted, and the air is blown from the front of the second air outlet 23.

As shown in fig. 3, when the air conditioner is in the bidirectional wind mode, the sliding plate 24 blocks the first air outlet, the second air outlet 23 is in an open state, the vertical swing blade 70 is adjusted, and wind blows from the front of the second air outlet 23. As shown in fig. 4, when the air conditioner is in the left independent air outlet mode, the left sliding plate 24 blocks the left first air outlet, the left second air outlet 23 is in an open state, the right second air outlet 23 is in a blocked state, the vertical swing blade 70 is adjusted, and air is blown from the front of the left second air outlet 23. As shown in fig. 5, when the air conditioner is in the right independent air outlet mode, the sliding plate 24 on the right blocks the first air outlet on the right, the second air outlet 23 on the left is in a blocked state, the second air outlet 23 on the right is in an open state, the vertical swing blade 70 is adjusted, and air is blown from the front of the second air outlet 23 on the right.

As shown in fig. 6, when the air conditioner is in the surround soft wind mode, the sliding plate 24 blocks the second air outlet 23, the first air outlet is in an open state, the vertical swing blade 70 is adjusted, and wind blows from the first air outlet through the wind outlet duct 22.

As shown in fig. 7, when the air conditioner is in the left independent soft wind mode, the left sliding plate 24 blocks the left second air outlet 23, the left first air outlet is in an open state, the vertical swing blade 70 is adjusted, and wind is blown from the left first air outlet through the wind outlet duct 22. As shown in fig. 8, when the air conditioner is in the right independent soft wind mode, the right sliding plate 24 blocks the second wind outlet 23, the right first wind outlet is in the open state, the vertical swing blade 70 is adjusted, and wind is blown from the right first wind outlet through the wind outlet duct 22.

When the air conditioner is in a front air supply and bidirectional air mode, the air conditioner can blow out large air quantity to the front so as to meet the requirements of large air quantity and rapid cooling. When the air conditioner is in the left and right independent air-out mode, the air conditioner can blow out great amount of wind to one side in the front to satisfy the demand of great amount of wind, rapid cooling, and the independent air-out of unilateral makes the air conditioner consumption reduce, environmental protection and energy saving more. When the air conditioner is in the surrounding soft air mode, the air supply angles of the air to the left side and the right side are larger, and from the aerodynamic perspective, the air flows on the two sides form two backflow areas in the middle area, so that the air conditioner can feel comfortable and soft cool air and can avoid direct blowing of cold air. When the air conditioner is in a left independent soft wind mode and a right independent soft wind mode, the air conditioner is suitable for being used under the conditions that people who are afraid of cold and heat coexist in a room and cold wind blows directly, and air is exhausted independently from one side, so that the power consumption of the air conditioner is reduced, and the air conditioner is more environment-friendly and energy-saving.

In some embodiments, the air conditioning indoor unit further includes two crossflow blowers 50 and an evaporator 91. An air inlet 92 is provided in the housing. The outlet duct 22 is defined by a volute of the cross-flow fan 50 and a volute tongue at the rear side of the volute. The volute and the volute tongue of the cross-flow fan 50 define the air outlet duct 22 by the structure of the cross-flow fan, so that the structure is more compact, other redundant parts are avoided, and the cross-flow fan is safer and more reliable. During operation, under the action of the cross flow fan 50, indoor air enters the inside of the casing 10 of the indoor unit of the air conditioner through the air inlet 92, forms heat exchange air after completing forced convection heat exchange with the evaporator 91, and is then discharged through the air outlet duct 22.

In some embodiments, the front guiding wall 41 of the air outlet duct 22 is connected to an end of the second air outlet 23 adjacent to the second air outlet portion, and the rear guiding wall 42 of the air outlet duct 22 is connected to a rear end of the first air outlet. The front air guide wall 41 and the rear air guide wall 42 are simple in structure, convenient to design, matched with the first air outlet and the second air outlet 23, and convenient to air out.

In some embodiments, the slide plate 24 is inside the first outlet vent when in the first position. As shown in fig. 2, an end portion of the rear air guiding wall 42 of the air outlet duct 22 connected to the first air outlet is provided with a mounting groove 60 for accommodating an end portion of the sliding plate 24. That is, when the sliding plate 24 is at the first position and is located at the inner side of the first air outlet, one end of the sliding plate 24 is just clamped in the mounting groove 60. Compact structure for first air outlet can not leak out, and the guide is blown to second air outlet 23. The slide plate 24 is in the second position, within the second outlet 23. Preferably, the thickness of the slide plate 24 is the same as the thickness of the front panel of the housing 10, so that the inner wall of the slide plate 24 is flush with the inner wall of the front panel and the outer wall of the slide plate 24 is flush with the outer wall of the front panel; the length of the sliding plate 24 is adapted to the length of the second air outlet 23, so as to ensure that no obvious gap is formed on the front panel, and thus the front surface of the air-conditioning indoor unit is more attractive. And slide 24 just blocks up second air outlet 23 completely for the wind that blows to first air outlet can not leak from second air outlet 23, and then makes the refrigeration effect of air conditioner better.

In some embodiments, as shown in fig. 9, the slide 24 is transitioned between the first and second positions under the guidance of the ramp assembly. The slide assembly includes a first slide 81 and a second slide 82. The first slide way 81 extends in the front-rear direction, and the front end of the first slide way 81 is adjacent to the front end of the corresponding first air outlet. The front end of the second slideway 82 is located on the side of the front end of the first slideway 81 departing from the first air outlet, and the second slideway 82 extends from the front end thereof to the rear and to the first air outlet.
