[0031] Reference below Figure 1-Figure 5 An air conditioner indoor unit 100 according to an embodiment of the present invention is described.

[0032] Reference Figure 1 , Figure 2 and Figure 5 According to an embodiment of the present invention, the air conditioner indoor unit 100 comprises: a casing 1, a first air outlet 11 and a second air outlet 12 are arranged in the casing 1, the first air outlet 11 is provided with a first air outlet 111, and the second air outlet 12 is provided with a second air outlet 121. That is to say, the air conditioner indoor unit 100 in the embodiment of the present invention has at least two air outlets, and when the air conditioner is discharged, the first air outlet 111 can be selected to discharge air, the second air outlet 121 can be selected, and the first air outlet 111 and the second air outlet 121 can be selected to discharge air at the same time, which increases the air outlet mode of the air conditioner indoor unit 100, and when the first air outlet 111 and the second air outlet 121 discharge air at the same time, the air outlet area of ​​the air conditioner indoor unit 100 is increased, the air outlet volume of the air conditioner indoor unit 100 is increased, and the air conditioning effect of the air conditioner indoor unit 100 is improved.

[0033] The air conditioning indoor unit 100 also includes: a first air guide member 2 and a second air guide member 3. The first air guide member 2 is movably arranged on the casing 1 to open or close the first air outlet 111. That is to say, the first air guide member 2 is movably arranged at the first air outlet 111. When the air conditioner needs to discharge air through the first air outlet 111, the first air guide member 2 opens the first air outlet 111, and the first air guide member 2 can also guide the air outlet direction at the first air outlet 111. When the air conditioner does not need to use the first air outlet 111, the first air guide member 2 can close the first air outlet 111 to prevent external dust from entering the first air outlet 111. The first air guide member 2 can also block the inside of the first air outlet 111 to improve the aesthetics of the air conditioning indoor unit 100.

[0034] Reference Figure 4 The second air guide member 3 is movably arranged on the casing 1 to open or close the second air outlet 121, that is, the second air guide member 3 is movably arranged at the second air outlet 121. When the air conditioner needs to discharge air through the second air outlet 121, the second air guide member 3 opens the second air outlet 121, and the second air guide member 3 can also guide the air outlet direction at the second air outlet 121. When the air conditioner does not need to use the second air outlet 121, the second air guide member 3 can close the second air outlet 121 to prevent external dust from entering the second air outlet 121. The second air guide member 3 can also block the inside of the second air outlet 121 to improve the aesthetics of the air conditioner indoor unit 100.

[0035] Reference Figure 2 , Figure 4 and Figure 5 The air conditioner indoor unit 100 further includes a third air guide 4, which is movably arranged in the housing 1 to guide the air to flow to the first air outlet 11 and / or the second air outlet 12. When the air conditioner indoor unit 100 needs to use the first air outlet 111 to discharge air, the third air guide 4 guides the air to flow to the first air outlet 11, reduces the air to flow to the second air outlet 12, and reduces wind loss; when the air conditioner indoor unit 100 needs to use the second air outlet 121 to discharge air, the third air guide 4 guides the air to flow to the second air outlet 12, reduces the air to flow to the first air outlet 11, and reduces wind loss; the third air guide 4 can also guide the air to be diverted to the first air outlet 11 and the second air outlet 12, so that the first air outlet 111 and the second air outlet 121 can discharge air at the same time, thereby increasing the air volume of the air conditioner indoor unit 100 and improving the air conditioning effect of the air conditioner indoor unit 100.

[0036] According to the air-conditioning indoor unit 100 of the embodiment of the present invention, the first air outlet 111 and / or the second air outlet 121 can be selected for air outlet, thereby increasing the air outlet modes of the air-conditioning indoor unit 100. Moreover, when the first air outlet 111 and the second air outlet 121 discharge air at the same time, the air outlet area of ​​the air-conditioning indoor unit 100 is increased, thereby increasing the air outlet volume of the air-conditioning indoor unit 100. A third air guide member 4 for guiding air to flow toward the first air outlet 11 and / or the second air outlet 12 is also provided inside the casing 1, thereby reducing wind loss and improving the air conditioning effect of the air-conditioning indoor unit 100.

[0037] In some specific embodiments, the first air outlet 111 is located on the front surface of the casing 1, and the second air outlet 121 is located on the bottom wall of the casing 1. That is, the air conditioner indoor unit 100 can send air forward through the first air outlet 111, can also send air downward through the second air outlet 121, and can also send air forward through the first air outlet 111 and send air downward through the second air outlet 121 at the same time.

[0038] In the above technical solution, the first air outlet 111 and the second air outlet 121 are respectively arranged at different positions of the housing 1 for supplying air in different directions, thereby increasing the air supply area of ​​the air conditioner indoor unit 100, facilitating the diffusion of the air conditioner air in the indoor environment, and improving the temperature adjustment capability of the air conditioner indoor unit 100. Furthermore, when the air conditioner uses the first air outlet 111 and the second air outlet 121 to supply air at the same time, the air conditioner air is supplied forward and downward respectively, reducing the possibility of the air conditioner air blowing directly on the human body, and effectively improving the comfort of the air conditioner air.

[0039] In some embodiments, the first air guide 2 is rotatably disposed on the housing 1, and the first air guide 2 can be rotated to completely block the first air outlet 111 to close the first air outlet 111, and the first air guide 2 can also be rotated to avoid the first air outlet 111 to open the first air outlet 111. And when the first air guide 2 is in the state of opening the first air outlet 111, its own angle can also be adjusted to adjust the air outlet direction of the first air outlet 111.

[0040] Through the above technical solution, the first air guide member 2 has a simple structure and is easy to manufacture. The first air guide member 2 is rotatably connected to the casing 1, and the connection method is simple, which reduces the cost of the air conditioner indoor unit 100.

[0041] In some specific embodiments, the air conditioner indoor unit 100 is provided with a first rotating shaft 13 for driving the first air guide member 2 to rotate, and the first rotating shaft 13 is connected to the output end of the motor. The extension direction of the first rotating shaft 13 is parallel to the length direction of the air conditioner indoor unit 100, the first rotating shaft 13 is located at the front end and the bottom end of the internal space of the casing 11, and the first rotating shaft 13 is located below the first air outlet 11. The first air guide member 2 is constructed as an air guide plate, and the first air guide member 2 is provided with a first connecting arm 21 on one side facing the first rotating shaft 13, and the first air guide member 2 is connected to the first rotating shaft 13 through the first connecting arm 21, so that when the motor drives the first rotating shaft 13 to rotate, the first rotating shaft 13 drives the first air guide member 2 to rotate.

[0042] Reference Figure 1 When the first air guide member 2 rotates to close the first air outlet 111, one end of the first air guide member 2 away from the first rotating shaft 13 stops at the upper edge of the first air outlet 111, and one end of the first air guide member 2 close to the first rotating shaft 13 stops at the lower edge of the first air outlet 111.

[0043] Reference Figure 2 When the first air guide 2 rotates to open the first air outlet 111, the first air guide 2 rotates clockwise, and when the end of the first air guide 2 close to the first rotating shaft 13 abuts against the housing 1, the first air guide 2 completely opens the first air outlet 111, and the opening of the first air outlet 111 is the largest. And because the end of the first air guide 2 close to the first rotating shaft 13 abuts against the housing 1, it can also play a role in wind-driving, blocking the air from flowing downward.

[0044] In some specific embodiments, the second air guide member 3 is rotatably disposed on the housing 1, and the second air guide member 3 can be rotated to completely block the second air outlet 121 to close the second air outlet 121, and the second air guide member 3 can also be rotated to avoid the second air outlet 121 to open the second air outlet 121. When the second air guide member 3 is in the state of opening the second air outlet 121, its own angle can also be adjusted to adjust the air outlet direction of the second air outlet 121.

[0045] Through the above technical solution, the second air guide member 3 has a simple structure and is easy to manufacture. The second air guide member 3 is rotatably connected to the casing 1, and the connection method is simple, which reduces the cost of the air conditioner indoor unit 100.

[0046] In some specific embodiments, the air conditioner indoor unit 100 is provided with a second rotating shaft 14 for driving the second air guide member 3 to rotate, and the second rotating shaft 14 is connected to the output end of the motor. The extension direction of the second rotating shaft 14 is parallel to the length direction of the air conditioner indoor unit 100, the second rotating shaft 14 is located at the front end and the bottom end of the internal space of the casing 11, the second rotating shaft 14 is located behind the first rotating shaft 13 and is spaced apart from the first rotating shaft 13, and the second rotating shaft 14 is located in front of the second air outlet 12. The second air guide member 3 is constructed as an air guide plate, and the second air guide member 3 is provided with a second connecting arm on one side facing the second rotating shaft 14, and the second air guide member 3 is connected to the second rotating shaft 14 through the second connecting arm, so that when the motor drives the second rotating shaft 14 to rotate, the second rotating shaft 14 drives the second air guide member 3 to rotate.

[0047] Reference Figure 1 When the second air guide member 3 rotates to close the second air outlet 121, the end of the second air guide member 3 away from the second rotating shaft 14 stops at the rear edge of the second air outlet 121, and the end of the second air guide member 3 close to the second rotating shaft 14 stops at the front edge of the second air outlet 121.

[0048] Reference Figure 4 When the second air outlet 121 needs to be opened, the second air guide 3 rotates counterclockwise so that the end of the second air guide 3 away from the second rotation axis 14 is separated from the rear edge of the second air outlet 121. When the second air guide 3 rotates to open the second air outlet 121, the end of the second air guide 3 close to the second rotation axis 14 is located inside the housing 1, which can prevent air leakage and prevent the air from flowing forward.

[0049] Reference Figure 1 , Figure 4 and Figure 5 In some specific embodiments, the third air guide member 4 is constructed as an air guide plate and is rotatably arranged inside the casing 1, and the third air guide member 4 is located at the connecting point between the first air outlet 11 and the second air outlet 12, so that the third air guide member 4 can be rotated to guide the air flow to the first air outlet 11 and / or the second air outlet 12.

[0050] Reference Figure 4 , the third air guide 4 has a first state. When the third air guide 4 is in the first state, the third air guide 4 rotates to block the first air outlet 11 and cooperates with the second air guide 3 to guide the air to the second air outlet 121. At this time, the third air guide 4 guides the air-conditioned air to flow completely to the second air outlet 121, reducing wind loss and improving the air conditioning effect of the air-conditioning indoor unit 100. In addition, the third air guide 4 can cooperate with the second air guide 3 to guide the air, so that the air outlet of the second air outlet 121 is more controllable, further reducing wind loss.

[0051] In some specific embodiments, when the third air guide member 4 is in the first state, the third air guide member 4 rotates to overlap with the second air guide member 3 .

[0052] Through the above technical solution, when the air-conditioning indoor unit 100 discharges air through the second air outlet 12, the air flows directly to the second air guide member 3 under the guidance of the third air guide member 4, and is finally discharged into the room under the guidance of the second air guide member 3, thereby reducing the possibility of air colliding with other structures and ensuring the smoothness of air passing through the second air outlet 12.

[0053] In some embodiments, when the third air guide member 4 is in the first state, the first air guide member 2 closes the first air outlet 111 , further reducing the possibility of air flowing into the first air outlet 11 .

[0054] Reference Figure 5 In some embodiments, the third air guide member 4 is rotatably disposed inside the housing 1, and the third air guide member 4 also has a second state. When the third air guide member 4 is in the second state, the third air guide member 4 rotates to guide air to the first air outlet 11 and the second air outlet 12 respectively. At this time, the air conditioner indoor unit 100 can discharge air through the first air outlet 111 and the second air outlet 121 at the same time, thereby increasing the air output of the air conditioner indoor unit 100.

[0055] Reference Figure 2 In some embodiments, the third air guide member 4 is rotatably disposed inside the housing 1, and the third air guide member 4 also has a third state. When the third air guide member 4 is in the third state, the third air guide member 4 rotates to block the second air outlet 12 to guide the air to the first air outlet 11. At this time, the third air guide member 4 guides the air-conditioned air to flow completely to the first air outlet 111, reducing wind loss and improving the air conditioning effect of the air-conditioning indoor unit 100.

[0056] Reference Figure 2 , Figure 3 and Figure 4 In some specific embodiments, the air duct inlet 122 of the second air outlet 12 is arranged on the inner wall of the first air outlet 11, and the third air guide member 4 is used to open or close the air duct inlet 122, that is, when the third air guide member 4 is in the third state, the third air guide member 4 closes the air duct inlet 122, thereby preventing air from entering the second air outlet 12.

[0057] Through the above technical solution, when the air-conditioning indoor unit 100 discharges air through the first air outlet 111, the third air guide member 4 closes the air duct inlet 122, and the third air guide member 4 guides the air-conditioning outlet air to flow completely to the first air outlet 111, thereby reducing wind loss and improving the air conditioning effect of the air-conditioning indoor unit 100.

[0058] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the third air guide 4 is provided with a plurality of rotatable shutters 5, and the plurality of shutters 5 are arranged at intervals along the length direction of the third air guide 4 (i.e., the left and right direction of the air conditioner indoor unit 100). The air conditioner indoor unit 100 can guide the air to the left or right through the plurality of shutters 5 on the third air guide 4. The air conditioner indoor unit 100 can also form a left and right air supply mode by driving the plurality of shutters 5 to rotate back and forth in the left and right directions. The air supply area of ​​the air conditioner indoor unit 100 is effectively increased, and the temperature regulation effect of the air conditioner indoor unit 100 is improved.

[0059] Because the shutter 5 is arranged on the third air guide member 4, the shutter 5 can rotate with the rotation of the third air guide member 4. Figure 4 When the third air guide 4 rotates to the first state, the shutter 5 is located on the side of the third air guide 4 facing the second air outlet 12. At this time, the shutter 5 can guide the flow direction of the air in the second air outlet 12, thereby improving the comfort of the second air outlet 121 when the air is discharged. Figure 2 When the third air guide member 4 rotates to the third state, the louver 5 is located on the side of the third air guide member 4 facing the first air outlet 11. At this time, the louver 5 can guide the flow direction of the air in the first air outlet 11, thereby improving the comfort of the first air outlet 111 when air is discharged.

[0060] In some embodiments, when the air conditioning indoor unit 100 is in a closed state, the first air guide member 2 closes the first air outlet 111, the second air guide member 3 closes the second air outlet 121, and the third air guide member 4 is in a third state, that is, the third air guide member 4 closes the air duct inlet 122 of the second air outlet 12, and the louver 5 is located on the side of the third air guide member 4 facing the first air outlet 11.

[0061] In some specific embodiments, the air conditioner indoor unit 100 has a first air supply mode, which is a mode of discharging air through the first air outlet 11 and the first air outlet 111. In the first air supply mode, the first air outlet 111 is opened and the second air outlet 121 is closed, and the third air guide 4 rotates to supply air toward the first air outlet 111.

[0062] When the air conditioner indoor unit is in the first air supply mode, the third air guide member 4 can be rotated to set the air outlet end facing forward, or the third air guide member 4 can be rotated to set the air outlet end facing forward and upward, or the third air guide member 4 can be rotated to set the air outlet end facing forward and downward, as long as the third air guide member 4 can guide the air flow to the first air outlet 111.

[0063] Reference Figure 2 When the indoor unit of the air conditioner is in the first air supply mode, and the third air guide member 4 is rotated to the air outlet end facing forward and downward, the third air guide member 4 has a smaller obstruction effect on the air outlet of the air conditioner.

[0064] Furthermore, when the air-conditioning indoor unit is in the first air supply mode, the third air guide member 4 rotates to the point where the air outlet end is facing forward and downward and the third air guide member 4 closes the air duct inlet 122, wind loss caused by air entering the second air outlet duct 12 is avoided. At this time, the air-conditioning indoor unit 100 has the maximum air outlet.

[0065] When the air conditioner indoor unit 100 needs to be switched from the closed state to the first air supply mode, the first air guide 2 is driven to rotate clockwise to open the first air outlet 111. Because the third air guide 4 is in a state of closing the air duct inlet 122 of the second air outlet 12 in the closed state, the third air guide 4 does not need to rotate at this time, so that the air conditioner indoor unit 100 has a maximum air output.

[0066] In some specific embodiments, when the air-conditioning indoor unit 100 is in the first air supply mode, the louver 5 is located on the side of the third air guide member 4 facing the first air outlet 11, and the air-conditioning indoor unit 100 can also drive the louver 5 to rotate left and right to change the air outlet direction of the first air outlet 111, thereby improving the comfort of the air outlet in the first air supply mode.

[0067] Reference Figure 2 and Figure 3 In some further embodiments, because in the first air supply mode, the third air guide member 4 can be in different states of air guide. Because the first air supply mode includes a plurality of different modes, for example, the first air supply mode includes a maximum air outlet mode, refer to Figure 2 In the maximum air outlet mode, the third air guide member 4 closes the air duct inlet 122 of the second air outlet duct 12 .

[0068] Reference Figure 3 The first air supply mode also includes a cold wind prevention mode, in which the outlet end of the third air guide 4 guides the air forward and upward. When the air conditioner indoor unit 100 is in the cold wind prevention mode, the air conditioner indoor unit 100 cools, and the third air guide 4 can guide the cold air forward and upward, reducing the possibility of the cold air blowing directly on the human body. Because the cold air is suitable for flowing downward, in the embodiment of the present invention, the third air guide 4 can guide the cold air forward and upward to form a canopy-style air supply, which is conducive to the diffusion of cold air in the room, and improves the effect of the air conditioner indoor unit 100 in reducing the indoor temperature.

[0069] When the air-conditioning indoor unit 100 needs to be switched from the maximum air outlet mode to the cold wind prevention mode, the third air guide member 4 is driven to rotate counterclockwise so that the air outlet end of the third air guide member 4 is arranged forward and upward.

[0070] Reference Figure 4In some embodiments, the air conditioner indoor unit 100 has a heating mode. In the heating mode, the first air outlet 111 is closed, the second air guide 3 opens the second air outlet 121 and the air outlet end of the second air guide 3 extends backward and downward, and the third air guide 4 cooperates with the second air guide 3 to guide air to the second air outlet 121.

[0071] Through the above technical solution, when the air conditioner indoor unit 100 is in the heating mode, the hot air can be sent backward and downward through the second air outlet 121 to form a wall-adhering flow to prevent the hot air from blowing directly on the human body, thereby improving the comfort of the air conditioner air outlet. Moreover, because the hot air is suitable for upward flow, in the embodiment of the present invention, the hot air can be guided backward and downward, which is conducive to the diffusion of the hot air in the room, thereby improving the effect of the air conditioner indoor unit 100 in raising the indoor temperature. Moreover, when the air conditioner indoor unit 100 is in the heating mode, the shutter can also be driven to rotate left and right to change the air outlet direction of the second air outlet 121, thereby improving the comfort of the air outlet in the heating mode.

[0072] When the air conditioner indoor unit 100 needs to be switched from the off state to the heating mode, the second air guide 3 is driven to rotate counterclockwise to open the second air outlet 121, and the third air guide 4 is driven to rotate counterclockwise to overlap with the second air guide 3. At this time, the shutter 5 is located on the side of the third air guide 4 facing the second air outlet 12.

[0073] Reference Figure 5 In some embodiments, the air conditioner indoor unit 100 has a second air supply mode. In the second air supply mode, the first air guide member 2 opens the first air outlet 111 and supplies air forward, the second air guide member 3 opens the second air outlet 121 and supplies air downward, and the third air guide member 4 guides the air to the first air outlet 11 and the second air outlet 12, respectively.

[0074] Through the above technical solution, when the air-conditioning indoor unit 100 is in the second air supply mode, the air-conditioning indoor unit 100 can discharge air through the first air outlet 111 and the second air outlet 121 at the same time, thereby increasing the air outlet area of ​​the air-conditioning indoor unit 100 and increasing the air outlet volume of the air-conditioning indoor unit 100. In addition, the air-conditioning indoor unit 100 supplies air forward through the first air outlet 111 and supplies air downward through the second air outlet 121, thereby increasing the air supply area of ​​the air-conditioning indoor unit 100, facilitating the diffusion of the air-conditioning outlet in the indoor environment and improving the temperature regulation capability of the air-conditioning indoor unit 100. The air supply mode of the air-conditioning indoor unit 100 supplying air forward through the first air outlet 111 and supplying air downward through the second air outlet 121 also reduces the possibility of the air-conditioning outlet blowing directly on the human body, thereby effectively improving the comfort of the air-conditioning outlet.

[0075] When it is necessary to switch the air-conditioning indoor unit 100 from the closed state to the second air supply mode, the first air guide member 2 is driven to rotate clockwise to open the first air outlet 111, the second air guide member 3 is driven to rotate counterclockwise to open the second air outlet 121, and the third air guide member 4 is driven to rotate clockwise to the second state (i.e., the third air guide member 4 is driven to rotate to guide the air to the first air outlet 11 and the second air outlet 12, respectively).

[0076] The air conditioner according to the embodiment of the present invention includes the air conditioner indoor unit 100 in the above technical solution.

[0077] According to the air conditioner of the embodiment of the present invention, the air-conditioning indoor unit 100 can choose to discharge air through the first air outlet 111 and / or the second air outlet 121, thereby increasing the air outlet modes of the air-conditioning indoor unit 100. When the first air outlet 111 and the second air outlet 121 discharge air at the same time, the air outlet area of ​​the air-conditioning indoor unit 100 is increased, and the air outlet volume of the air-conditioning indoor unit 100 is increased. A third air guide member 4 for guiding air to flow to the first air outlet 11 and / or the second air outlet 12 is also provided inside the casing 1, thereby reducing wind loss and improving the air conditioning effect of the air conditioner.
