[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an air conditioner indoor unit, which includes an indoor unit housing 10. Specifically, the air conditioner indoor unit in this embodiment includes: an air inlet 11, a first air outlet 12 and a second air outlet 13. The air inlet 11 is arranged at the top of the indoor unit housing 10; the first air outlet 12 is arranged at the top of the indoor unit housing 10; and the second air outlet 13 is arranged at the bottom of the indoor unit housing 10. The indoor unit housing 10 has an air outlet area 19, and the air outlet area 19 is selectively connected with the first air outlet 12 and the second air outlet 13, so that the gas in the air inlet 11 enters the first air outlet 12 or the first air outlet 12 through the air outlet area 19.

[0030] Since the air conditioner indoor unit in this embodiment has a first air outlet 12 arranged at the top of the indoor unit housing 10 and a second air outlet 13 arranged at the bottom of the indoor unit housing 10, the corresponding air outlet can be selected to discharge air according to the cooling and heating modes of the air conditioner indoor unit. Specifically, when the air conditioner indoor unit is in the heating mode, the air outlet area 19 is connected with the second air outlet 13, and the air in the indoor unit housing 10 will enter the room through the second air outlet 13, that is, the air outlet mode of lower air outlet is adopted, and the hot air is sent to various positions in the room along the second air outlet 13, which can solve the problem that the hot air does not fall to the ground, and realizes carpet-style air supply. When the air conditioner indoor unit is in the cooling mode, the air outlet area 19 is connected with the first air outlet 12, and the air in the indoor unit housing 10 will enter the room through the first air outlet 12, that is, the air outlet mode of upper air outlet is adopted, and the cold air will not blow towards people, realizing cooling parallel shower-style air supply. The air-conditioning indoor unit in this embodiment can realize the function of upper and lower air outlet, has high comfort, and can realize upper and lower separate air outlet. By adopting different air outlet methods in different modes, it can solve the problem that cold air blows directly on people when the air-conditioning indoor unit is cooling and hot air is difficult to fall to the ground when heating, thereby improving indoor comfort.

[0031] Specifically, the indoor unit housing 10 in this embodiment also includes a first sweeping blade 30, which is rotatably arranged in the air outlet area 19 to sweep the wind in the air outlet area 19 to the second air outlet 13 and blow it into the room. Preferably, the sweeping direction of the first sweeping blade 30 is perpendicular to the air outlet direction of the second air outlet 13, so that the wind from the second air outlet 13 can be better blown into the room. Such a setting is adopted to facilitate better sweeping of the air at the air outlet area 19 to the second air outlet 13, so as to better improve the indoor comfort. When the first air outlet 12 is blowing out air and the second air outlet 13 is not blowing out air, the first sweeping blade 30 is stationary in the air outlet area 19.

[0032] In this embodiment, the indoor unit housing 10 further includes an air duct 90, which is used to communicate with the air outlet area 19, and the air duct 90 has a closed state and an open state; when the air duct 90 is in a closed state, the air in the air outlet area 19 is blown into the room from the second air outlet 13; when the air duct 90 is in an open state, the end of the air duct 90 away from the air outlet area 19 forms a first air outlet 12, and the air in the air outlet area 19 is blown into the room from the first air outlet 12 through the air duct 90. When the air duct 90 is in an open state and the second air outlet 13 is closed, the end of the air duct 90 away from the air outlet area 19 forms the first air outlet 12, and the air in the air outlet area 19 is blown into the room from the first air outlet 12 through the air duct 90. With such a setting, when the second air outlet 13 is blowing air, the air duct 90 is in a closed state; when the first air outlet 12 is blowing air, the air duct 90 is in an open state. By providing the air duct 90 , the air outlet area 19 can be selectively connected to the first air outlet 12 or the second air outlet 13 .

[0033] Specifically, the indoor unit housing 10 in this embodiment includes a first air duct housing 14 and a second air duct housing 15; the second air duct housing 15 is movably arranged outside the first air duct housing 14, and the second air duct housing 15 is arranged opposite to the first air duct housing 14 to enclose the air duct 90; the second air duct housing 15 has a stowed position and an open position, and the second air duct housing 15 is movably arranged between the stowed position and the open position; when the second air duct housing 15 is in the stowed position, the air duct 90 is in a closed state; when the second air duct housing 15 is in the open position, the air duct 90 is in an open state. The air duct 90 composed of the first air duct housing 14 and the second air duct housing 15 has a simple structure, and it is easy to achieve the closed state or the open state of the air duct 90.

[0034] Specifically, the indoor unit housing 10 in this embodiment further includes a top plate 17. When the second air duct housing 15 is in the retracted position, one end of the second air duct housing 15 away from the air outlet area 19 is butted against the top plate 17 to seal the air duct 90. When the second air duct housing 15 is in the open position, one end of the second air duct housing 15 away from the air outlet area 19 is separated from the top plate 17 to form the first air outlet 12. With such a configuration, the overall layout of the indoor unit housing 10 is optimized, which can facilitate the compactness of the overall structure.

[0035] In this embodiment, the indoor unit housing 10 further includes a bottom plate 16 and a wall surface 18, and the wall surface 18 is used to install the air conditioner indoor unit on the indoor wall. The bottom plate 16 is arranged opposite to the top plate 17, and the bottom plate 16 is spaced apart from the second air duct housing 15, and a second air outlet 13 is formed at the gap between the bottom plate 16 and the second air duct housing 15. Preferably, a corresponding baffle structure can be provided at the second air outlet 13, so that the second air outlet 13 can be conveniently opened or closed, so that the first air outlet 12 and the second air outlet 13 can discharge air respectively.

[0036] In order to better drive the movement of the second air duct housing 15, the indoor unit housing 10 includes a driving mechanism, which is connected to the second air duct housing 15 to drive the second air duct housing 15 to move between the stowed position and the opened position.

[0037] Specifically, the driving mechanism includes a driving rod 40, a first connection end of the driving rod 40 is hinged to the first air duct housing 14, a second connection end of the driving rod 40 is hinged to the second air duct housing 15, and the driving rod 40 rotates relative to the first connection end to drive the second air duct housing 15 to move toward or away from the first air duct housing 14. The driving rod 40 has a simple structure, is easy to produce and manufacture, and can stably drive the second air duct housing 15 to move through the driving rod 40.

[0038] In order to improve the stability of movement, there are multiple driving rods 40, and the multiple driving rods 40 are arranged at intervals in the air duct 90 to better drive the second air duct housing 15 to move.

[0039] In this embodiment, the air conditioner indoor unit further includes a second sweeping blade 50, which is movably disposed in the air duct 90. With such a configuration, the second sweeping blade 50 can better sweep the air in the air duct 90 to the first air outlet 12, and the air enters the room from the first air outlet 12, thereby increasing the sweeping range and improving the indoor comfort.

[0040] Specifically, the second wind sweeping blade 50 has a folded state and a working state. When the air duct 90 is in a closed state, the second wind sweeping blade 50 is in a folded state; when the air duct 90 is in an open state, the second wind sweeping blade 50 is in a working state. When the air conditioner is in a cooling mode, the second air outlet 13 is closed, the air duct 90 is in an open state, the distance between the first air duct housing 14 and the second air duct housing 15 is large, and the internal space of the air duct 90 is large. At this time, the internal space of the air duct 90 is sufficient, and the second wind sweeping blade 50 can move in the air duct 90 to put the second wind sweeping blade 50 in a working state, so that the air in the air duct 90 can be swept to the first air outlet 12, so that the first air outlet 12 can discharge air. When the air conditioner is in heating mode, the air duct 90 is in a closed state, air is discharged from the second air outlet 13, the distance between the first air duct shell 14 and the second air duct shell 15 is small, and the space in the air duct 90 is small. The second sweeping blade 50 can be tilted or folded in the air duct 90 to put the second sweeping blade 50 in a folded state.

[0041] Specifically, when the second sweeping blade 50 is in working state, the second sweeping blade 50 is rotatably arranged in the air duct 90 to sweep the air in the air duct 90 to the first air outlet 12 and blow it into the room. The second sweeping blade 50 is mainly used to sweep the air left and right. Preferably, the sweeping direction of the second sweeping blade 50 is perpendicular to the air outlet direction of the first air outlet 12, so that the wind at the first air outlet 12 can blow to a wider range of the room, so as to better improve the indoor comfort.

[0042] The indoor unit housing 10 in this embodiment further includes a heat exchange chamber 100, which is in communication with the air outlet area 19. A fan 60 and a heat exchanger 70 are disposed in the heat exchange chamber 100, and the heat exchanger 70 is disposed around at least a portion of the fan 60. The heat exchange chamber 100 is used to perform heat exchange on the air entering the indoor unit housing 10 from the room. By arranging the heat exchanger 70 around at least a portion of the fan 60, the air entering the indoor unit housing 10 can be better fully heat exchanged, thereby improving the heat exchange effect.

[0043] In order to further improve the heat exchange effect, the heat exchanger 70 in this embodiment has a groove section, and at least part of the fan 60 is arranged in the groove section. The air after heat exchange in the heat exchange chamber 100 can selectively enter the room from the first air outlet 12 or the second air outlet 13.

[0044] like Figure 1 and Figure 2 As shown, the heat exchanger 70 may be a straight plate heat exchanger 70 with a bend, or may be composed of three sections of straight plate heat exchangers 70 spliced ​​together. Alternatively, the heat exchanger 70 may be a V-shaped heat exchanger 70 or a U-shaped heat exchanger 70.

[0045] In order to facilitate air intake through the air inlet 11, the air conditioner indoor unit in this embodiment further includes a top plate 17, and the air inlet 11 is arranged on the top plate 17. In order to facilitate better heat exchange of the air entering the indoor shell, in this embodiment, the heat exchanger 70 is arranged opposite to the air inlet 11, and the heat exchanger 70 is arranged on the top of the fan 60. With such an arrangement, under the action of the fan 60, the air in the indoor unit shell 10 can be selectively connected to the first air outlet 12 or the second air outlet 13 after heat exchange through the heat exchanger 70.

[0046] In this embodiment, the indoor unit housing 10 includes a heat exchange cavity 100, and the air duct 90 is arranged around at least part of the heat exchange cavity 100. With such an arrangement, the internal structure of the air conditioner indoor unit can be made more compact and the internal layout can be optimized. Specifically, in this embodiment, the bottom plate 16 and the first air duct housing 14 are used to enclose the heat exchange cavity 100, the first air duct housing 14 and the second air duct housing 15 arranged outside the first air duct housing 14 are used to enclose the air duct 90, the air duct 90 is located outside the heat exchange cavity 100, and the air duct 90 is connected to the heat exchange cavity 100 through the air outlet area 19. By adopting such an internal layout, on the one hand, the internal structure can be made more compact and reasonable, and the internal space of the air conditioner indoor unit can be fully utilized. On the other hand, by arranging the air duct 90 outside the heat exchange cavity 100, it is convenient for the air outlet area 19 to be selectively connected with the first air outlet 12 and the second air outlet 13, which is conducive to selecting the corresponding air outlet mode in different working modes.

[0047] Specifically, the second air outlet 13 is rotatably provided with an air guide plate 20, which has a first position and a second position. The air guide plate 20 rotates between the first position and the second position to sweep the air at the second air outlet 13 to the room. When the air guide plate 20 is in the first position, the air guide plate 20 covers the second air outlet 13. When the air guide plate 20 covers the second air outlet 13, the second air outlet 13 is closed. At this time, if the air duct 90 is in an open state, air can be discharged from the first air outlet 12; when the air duct 90 is in a closed state, the air guide plate 20 can be rotated between the first position and the second position, so that the air at the air outlet area 19 is guided from the second air outlet 13 to the room.

[0048] Specifically, a plurality of air guide plates 20 may be provided at the second air outlet 13. When the second air outlet 13 is closed, the plurality of air guide plates 20 are all in the first position to cover the second air outlet 13. In order to facilitate the discharge of air in the indoor unit housing 10 from the second air outlet 13, the air guide plates 20 in this embodiment can be rotated to open to an angle within a range of 80° to 90° with the bottom plate 16. In this way, the hot air after heat exchange by the heat exchanger 70 will be blown vertically downward along the air guide surfaces of the plurality of air guide plates 20, solving the problem of the difficulty of hot air falling to the ground during air conditioning heating, and realizing heating carpet-style air supply. At the same time, the first sweeping blade 30 works to sweep the air left and right, so as to better deliver the air from the second air outlet 13 into the room.

[0049] When the indoor unit of the air conditioner is in heating mode, the plurality of driving rods 40 move simultaneously to drive the second air duct housing 15 to move in a direction away from the first air duct housing 14, the first air outlet 12 opens, and the second air sweeping blade 50 also stands up with the movement of the second air duct housing 15, so that the second air sweeping blade 50 smoothly enters the working state from the retracted state. At the same time, the plurality of air guide plates 20 arranged at the second air outlet 13 will move closely along the movement direction of the second air duct housing 15 without rotating, so as to ensure that there is no gap between the second air duct housing 15 and the plurality of air guide plates 20.

[0050] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: avoiding the phenomenon that the hot air from the air-conditioning indoor unit is difficult to fall to the ground and the cold air blows directly on people; realizing different air outlet modes by driving the driving mechanism, improving the comfort of the air outlet of the air conditioner, and optimizing the internal structure of the air-conditioning indoor unit.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
