[0058] Figure 1 It is a cross-sectional schematic diagram of an indoor air conditioner unit 20 according to an embodiment of the utility model.

[0059] refer to Figure 1As shown, this embodiment provides an indoor air conditioner unit 20. The indoor air conditioner unit 20 includes a housing 21 and an air duct divider. The housing 21 is provided with an air inlet and an air outlet. The air duct divider is disposed in the housing 21 and is configured to separate a first air supply duct located at the front side of the housing 21 and a second air supply duct located at the rear side of the housing 21, and the first air supply duct and the second air supply duct are connected to the air inlet and the air outlet, respectively.

[0060] The air duct partition includes a second air duct wall 32 and a third air duct wall 33. The second air duct wall 32 serves as the rear air duct wall of the first air supply duct; the third air duct wall 33 serves as the front air duct wall of the second air supply duct. The first end of the second air duct wall 32 is connected to the first end of the third air duct wall 33, and there is a gap between the connecting part and the air outlet, so that the airflows blown out from the first air supply duct and the second air supply duct are mixed at the gap; the first end of the second air duct wall 32 and the first end of the third air duct wall 33 are respectively located at the ends of the first air supply duct and the second air supply duct in the airflow direction.

[0061] refer to Figure 1 As shown, the duct divider of this embodiment is formed by connecting the second duct wall 32 as the rear duct wall of the first air supply duct and the third duct wall 33 as the front duct wall of the second air supply duct. The duct divider divides the first air supply duct and the second air supply duct from front to back, so that part of the air entering the housing 21 from the air inlet flows into the first air supply duct near the front side, and part flows into the second air supply duct near the rear side. Since the junction of the first end of the second duct wall 32 and the first end of the third duct wall 33 is spaced from the air outlet, the airflow flowing through the first air supply duct and the airflow flowing through the second air supply duct meet and mix before reaching the air outlet.

[0062] The air inlet of the indoor unit 20 of the air conditioner in this embodiment is usually opened on the top surface of the shell 21. In order to increase the air inlet area, in some optional implementations, the air inlet can also be opened on the upper part of the front side of the shell 21.

[0063] Figure 1 The dotted lines illustrate the positions of the two air guide plates arranged at the air outlet of the indoor unit 20 of the air conditioner in this embodiment when the air outlet is closed. The positions of the air guide plates at this time usually correspond to the positions of the air outlet, that is, the positions of the board surfaces of the air guide plates at this time can be regarded as the specific positions of the air outlet.

[0064] from Figure 1 It can be seen that since there is a gap between the junction of the first end of the second air duct wall 32 and the first end of the third air duct wall 33 and the air outlet, the ends of the first air supply duct and the second air supply duct are facing this gap, so the airflows blown out of the first air supply duct and the second air supply duct can meet and mix at the gap before reaching the air outlet.

[0065] The indoor air conditioner unit 20 of this embodiment is provided with an air duct partition to separate the first air supply duct and the second air supply duct in the housing 21, and the first air supply duct and the second air supply duct are connected at a position spaced from the air outlet, so that the airflows blown out of the first air supply duct and the second air supply duct can be mixed at the spaced position and then blown out of the air outlet. The indoor air conditioner unit 20 can provide a variety of different air supply modes by adjusting the airflows blown out of the first air supply duct and the second air supply duct.

[0066] For example, in some optional embodiments, the indoor air conditioner unit 20 further includes a first crossflow fan 23 and a second crossflow fan 24. By adjusting the rotation speed of the first crossflow fan 23 and the second crossflow fan 24, the airflow velocity of the first air supply duct and the second air supply duct can be changed, thereby affecting the main flow direction of the airflow blown out of the air outlet. In other words, by adjusting the rotation speed of the first crossflow fan 23 and the second crossflow fan 24, air supply modes such as long-distance air supply (higher air supply height), short-distance air supply (lower air supply height) and up and down sweeping air can be provided.

[0067] Or in some optional embodiments, the indoor unit 20 of the air conditioner further includes a heat exchanger 26, and the heat exchanger 26 includes a first heat exchange section 262 and a second heat exchange section 264. The first heat exchange section 262 and the second heat exchange section 264 correspond to the first air supply duct and the second air supply duct, respectively. By adjusting the amount of refrigerant circulating in the first heat exchange section 262 and the second heat exchange section 264, the temperature of the airflow flowing into the first air supply duct and the second air supply duct can be changed, thereby affecting the mixed temperature of the airflow blown out of the air outlet, and making the airflow blown out of the air outlet have cold and hot stratification. In other words, by adjusting the amount of refrigerant circulating in the first heat exchange section 262 and the second heat exchange section 264, air supply modes such as mixed uniform wind can be provided.

[0068] refer to Figure 1 As shown, in some optional implementations, the air conditioner indoor unit 20 further includes: a first cross-flow fan 23 , a second cross-flow fan 24 and a heat exchanger 26 .

[0069] The first crossflow fan 23 is arranged in the first air supply duct, and is used to promote the formation of an air flow that enters the shell 21 from the air inlet, flows through the first air supply duct, and is blown out from the air outlet. The second crossflow fan 24 is arranged in the second air supply duct, and is used to promote the formation of an air flow that enters the shell 21 from the air inlet, flows through the second air supply duct, and is blown out from the air outlet. The heat exchanger 26 is arranged in the shell 21, and a part of the heat exchanger 26 is located between the air inlet and the first crossflow fan 23, and a part of the heat exchanger 26 is located between the air inlet and the second crossflow fan 24, so that a part of the air entering from the air inlet flows through the heat exchanger 26 and enters the first air supply duct, and a part of the air flows through the heat exchanger 26 and enters the second air supply duct.

[0070] The indoor unit 20 of the air conditioner of this embodiment makes the first crossflow fan 23 and the second crossflow fan 24 correspond to a part of the heat exchanger 26, so that the airflow entering the first air supply duct and the second air supply duct can exchange heat through the heat exchanger 26. The first crossflow fan 23 and the second crossflow fan 24 are both arranged in the housing 21 in the transverse direction. By reasonably setting the shape of the heat exchanger 26, most or even all of the air entering the housing 21 from the air inlet needs to flow through the heat exchanger 26 before flowing to the first air supply duct or the second air supply duct.

[0071] In some optional implementations, the air conditioner indoor unit 20 further includes: a first air duct wall 31 and a fourth air duct wall 34 .

[0072] The first air duct wall 31 serves as the front air duct wall of the first air supply duct; the first end of the first air duct wall 31 extends to the upper side of the air outlet, and the second end is close to the first crossflow fan 23 and bent to form a volute tongue structure. The fourth air duct wall 34 serves as the rear air duct wall of the second air supply duct; the first end of the fourth air duct wall 34 extends to the lower side of the air outlet, and the second end is close to the second crossflow fan 24. The second end of the second air duct wall 32 is close to the first crossflow fan 23; the second end of the third air duct wall 33 is close to the second crossflow fan 24 and bent to form a volute tongue structure.

[0073] The indoor unit 20 of the air conditioner of this embodiment defines a first air supply duct by the first air duct wall 31 and the second air duct wall 32 spaced apart from each other, and defines a second air supply duct by the third air duct wall 33 and the fourth air duct wall 34 spaced apart from each other. The second ends of the first air duct wall 31 and the third air duct wall 33 are respectively close to the first cross-flow fan 23 and the second cross-flow fan 24 and form a volute tongue structure to cooperate with the rotation of the fan to define the flow direction of the airflow. This embodiment reasonably sets the positions and shapes of the first air duct wall 31, the second air duct wall 32, the third air duct wall 33 and the fourth air duct wall 34, so that the upper parts of the first cross-flow fan 23 and the second cross-flow fan 24 face upward toward the heat exchanger 26 and the air inlet, and the air supply direction is inclined forward and downward, corresponding to the air outlet opened at the lower part of the front side of the shell 21.

[0074] The ends of the first air supply duct and the second air supply duct refer to the opening positions defined at the ends of the respective air duct walls in the air flow direction. Taking the first air supply duct as an example, the end of the first air supply duct is the position between the first end of the first air duct wall 31 and the first end of the second air duct wall 32. The first end of the first air duct wall 31 extends to the upper side of the air outlet, so the end of the first air supply duct is close to the upper side of the air outlet; the first end of the fourth air duct wall 34 extends to the lower side of the air outlet, so the end of the fourth air supply duct is close to the lower side of the air outlet.

[0075] The upper side of the air outlet of the present embodiment is located at the lower end of the front side of the shell 21, which can be understood as the first end of the first air duct wall 31 extending forward to connect with the lower end of the front side of the shell 21, and making the connection as the upper side of the air outlet. Similarly, the lower side of the air outlet of the present embodiment is located at the front end of the bottom surface of the shell 21, which can be understood as the first end of the fourth air duct wall 34 extending forward and downward to connect with the front end of the bottom surface of the shell 21, and making the connection as the lower side of the air outlet. The two lateral sides of the air outlet are usually located on the lateral sides of the shell 21, and can be located at the position where the front ends of the two lateral walls extending outward from the first air supply duct and the second air supply duct connect with the shell 21.

[0076] In some optional embodiments, the third air duct wall 33 includes a volute tongue section bent at the second end to form a volute tongue structure, and an extension section extending forward from the volute tongue section to the first end, wherein the angle between the extension section and the horizontal plane is less than or equal to 6°.

[0077] refer to Figure 1 As shown, the second end of the third air duct wall 33 of this embodiment has a volute tongue section that is bent upward to form a volute tongue structure, and an extension section that extends forward from the volute tongue section to the first end and connects to the first end of the second air duct wall 32. The extension section can generally form a plane or an arc surface.

[0078] The extension section may be formed by extending forward from the tongue section horizontally or obliquely, but the angle θ between the extension section and the horizontal plane is usually less than or equal to 6°, that is, the extension section is parallel or substantially parallel to the horizontal plane, so that the flow direction of the airflow blown out of the second air supply duct is substantially toward the front. In the case where an angle is formed between the extension section and the horizontal plane, the extension section usually forms a downward inclined surface from the back to the front.

[0079] When the extension section is a curved surface, the angle between the extension section and the horizontal plane is the angle between the connecting line of the front and rear ends of the extension section and the horizontal plane.

[0080] In some optional embodiments, the heat exchanger 26 includes a first heat exchange section 262 located at the front side, and a second heat exchange section 264 located at the rear side; the first heat exchange section 262 and the second heat exchange section 264 are connected in parallel and are controlled separately.

[0081] The heat exchanger 26 of this embodiment is divided into two parts, front and back, wherein the first heat exchange section 262 located at the front side is opposite to the first air supply duct and the first crossflow fan 23 located at the front side of the duct partition, and the second heat exchange section 264 located at the rear side is opposite to the second air supply duct and the second crossflow fan 24 located at the rear side of the duct partition. The airflow flowing through the first heat exchange section 262 mainly flows to the first air supply duct, and the airflow flowing through the second heat exchange section 264 mainly flows to the second air supply duct.

[0082] The heat exchanger 26 is provided with a coil for the flow of refrigerant. The first heat exchange section 262 and the second heat exchange section 264 are connected in parallel in this embodiment, which means that the coil in the first heat exchange section 262 is connected in parallel with the coil in the second heat exchange section 264. By setting an electric three-way valve at the position where the coil in the first heat exchange section 262 and the coil in the second heat exchange section 264 are connected, or by setting electric valves on the coil in the first heat exchange section 262 and the coil in the second heat exchange section 264, respectively, the refrigerant flow in the first heat exchange section 262 and the second heat exchange section 264 can be adjusted and the on-off control can be performed, thereby changing the temperature of the airflow that flows through the first heat exchange section 262 and blows out from the first air supply duct, or flows through the second heat exchange section 264 and blows out from the second air supply duct.

[0083] In some optional embodiments, the air duct divider further includes: a divider plate 28 .

[0084] One end of the partition plate 28 is connected to the second end of the second air duct wall 32, and the other end extends to the connection between the first heat exchange section 262 and the second heat exchange section 264, so that the air flowing through the first heat exchange section 262 enters the first air supply duct, and the air flowing through the second heat exchange section 264 enters the second air supply duct.

[0085] The air duct partition of this embodiment further extends upward from the second end of the second air duct wall 32 near the second cross-flow fan 24 to the connection between the first heat exchange section 262 and the second heat exchange section 264 to form a partition plate 28, thereby separating the first air supply duct and the second air supply duct as a whole from front to back. The airflow flowing through the first heat exchange section 262 of the heat exchanger 26 can only flow to the first air supply duct, and the airflow flowing through the second heat exchange section 264 can only flow to the second air supply duct. Therefore, when the indoor unit 20 of the air conditioner controls the refrigerant flow in the first heat exchange section 262 and the second heat exchange section 264, the temperature of the airflow blown out of the first air supply duct and the second air supply duct is more controllable, and the mixing effect of the airflow is better.

[0086] In some optional embodiments, the diameter of the first cross-flow fan 23 is greater than the diameter of the second cross-flow fan 24 ; and the surface area of ​​the first heat exchange section 262 is greater than the surface area of ​​the second heat exchange section 264 .

[0087] refer to Figure 1 As shown, the first heat exchange section 262 of the heat exchanger 26 of this embodiment can be bent downward in the housing 21, so the surface area is larger than the second heat exchange section 264, and the heat exchange efficiency of the air flowing through is higher. In this embodiment, the diameter of the first crossflow fan 23 is correspondingly set to be larger than the diameter of the second crossflow fan 24, and the first crossflow fan 23 is used as the main fan of the indoor hanging unit 20 of the air conditioner. The shape and width of the first air supply duct and the second air supply duct are adapted to the size of the first crossflow fan 23 and the second crossflow fan 24.

[0088] In some optional embodiments, the ratio of the diameter of the first cross flow fan 23 to the diameter of the second cross flow fan 24 may be 5:4. For example, the diameter of the first cross flow fan 23 may be 80 mm, and the diameter of the second cross flow fan 24 may be 64 mm accordingly.

[0089] The diameters of first cross-flow fan 23 and second cross-flow fan 24 are the diameters of the rotational trajectories of the outermost ends of their respective blades.

[0090] Figure 2 It is a cross-sectional schematic diagram of an indoor air conditioner unit 20 according to another embodiment of the utility model.

[0091] refer to Figure 2 As shown, in some optional embodiments, the first end of the second air duct wall 32 is located behind the upper side of the air outlet in the front-to-back direction, and in front of the lower side of the air outlet; and the first end of the second air duct wall 32 is located below the upper side of the air outlet in the up-down direction, and above the lower side of the air outlet.

[0092] The first end of the second air duct wall 32 of the indoor unit 20 of the air conditioner of this embodiment is connected to the first end of the third air duct wall 33, so the first air supply duct and the second air supply duct also meet here. Since the position where the second air duct wall 32 and the third air duct wall 33 of this embodiment are connected is located behind the upper side of the air outlet in the front-to-back direction and in front of the lower side of the air outlet, and is located below the upper side of the air outlet in the up-down direction and above the lower side of the air outlet, the first air supply duct and the second air supply duct are each directly opposite to a part of the air outlet in the front-to-back direction and the up-down direction, and the shape of the air outlet enables the first air supply duct and the second air supply duct to discharge air smoothly at the same time.

[0093] In some optional implementations, the air conditioner indoor unit 20 further includes: a first air guide plate 41 and a second air guide plate 42 .

[0094] The first air guide plate 41 and the second air guide plate 42 are respectively arranged at the air outlet in a transverse direction, and are used to close the air outlet or adjust the airflow direction at the air outlet. When the first air guide plate 41 and the second air guide plate 42 are in the position of closing the air outlet, the first air guide plate 41 extends forward from the lower side of the air outlet, and the angle between the plate surface of the first air guide plate 41 and the horizontal plane is less than or equal to 10°; the second air guide plate 42 extends upward from the front end of the first air guide plate 41 to the upper side of the air outlet.

[0095] The air outlet of the indoor unit 20 of the air conditioner of this embodiment is opened transversely on the shell 21, so the first air guide plate 41 and the second air guide plate 42 arranged transversely rotate around the transversely extending rotation axis, and each can play the role of guiding air up and down. Figure 2The first air guide plate 41 and the second air guide plate 42 are shown in FIG. Figure 2 As shown, when the first air guide plate 41 is in a position to close the air outlet, one end of the first air guide plate 41 is located at the lower side of the air outlet, that is, at the first end of the fourth air duct wall 34, and extends toward the front side of the air conditioner indoor hanging unit 20.

[0096] It should be noted that the forward extension of the first air guide plate 41 is not limited to horizontal extension, but can be slightly inclined, that is, the plate surface of the first air guide plate 41 can extend horizontally forward, or can be inclined similar to the extension section of the third air duct wall 33. The angle between the plate surface of the first air guide plate 41 and the horizontal plane is less than or equal to 10°, that is, the plate surface of the first air guide plate 41 is parallel or substantially parallel to the horizontal plane, so that the flow direction of the airflow blown out along the plate surface of the first air guide plate 41 is substantially toward the front.

[0097] The plate surface of the first air guide plate 41 can be formed into a plane or an arc surface. When the plate surface is an arc surface, when the first air guide plate 41 is in a position to close the air outlet, the notch of the arc surface faces upward. In addition, when the plate surface is an arc surface, the angle between the plate surface of the first air guide plate 41 and the horizontal plane is the angle between the connecting line of the front and rear ends of the plate surface and the horizontal plane.

[0098] The first air guide plate 41 extends from the rear to the front to close part of the air outlet facing downward, and the second air guide plate 42 extends upward from the front end of the first air guide plate 41 to the upper side of the air outlet to close part of the air outlet facing forward. The specific inclination direction of the second air guide plate 42 is forward and upward.

[0099] Figure 2 The positions of the rotation axes of the first air guide plate 41 and the second air guide plate 42 are also indicated by dotted lines. Figure 2 As shown, in some optional embodiments, when the first air guide plate 41 and the second air guide plate 42 are in a position to close the air outlet, the rotation axis Q1 of the first air guide plate 41 is located near the upper side of its front end; and the rotation axis Q2 of the second air guide plate 42 is located near the upper side of the rear end of the first air guide plate 41.

[0100] Figure 3 yes Figure 2 The schematic diagram of the first air guide plate 41 of the indoor air conditioner 20 is shown in FIG. Figure 4 yes Figure 2 Another schematic diagram of the indoor unit 20 of the air conditioner is shown.

[0101] Taking the first air guide plate 41 as an example, the front end and the rear end of the first air guide plate 41 described in this embodiment are determined in the following manner:

[0102] The first air guide plate 41 is divided into a first section N1, a second section N2 and a third section N3 of equal length along the front-to-back direction. Figure 2 and Figure 3 As shown, the area corresponding to the first section N1 is close to the front end, the area corresponding to the third section N3 is close to the rear end, and the area corresponding to the second section N2 is close to the middle, and the same is true for other air guide plates.

[0103] When the first air guide plate 41 is inclined or its surface is curved, the position close to the front end, rear end or middle of the first air guide plate 41 depends on the position of the vertical projection on the surface (the curved surface is regarded as the plane where the connecting line of the front and rear ends of the air guide plate is located).

[0104] Figure 4 yes Figure 2 Another schematic diagram of the indoor unit 20 of the air conditioner is shown.

[0105] refer to Figure 2 and Figure 4 As shown, the rotation axis Q2 of the second air guide plate 42 of the present embodiment is far away from its own plate surface and located on the upper side of the rear end of the first air guide plate 41. When rotating, it can move downward with a rotation trajectory of a larger diameter without colliding with the first air guide plate 41 front and rear, and sufficient rotation space is reserved for the first air guide plate 41.

[0106] refer to Figure 4 As shown, the indoor unit 20 of the air conditioner in this embodiment can control the second air guide plate 42 to rotate while the first air guide plate 41 does not rotate, so that the plate surface of the first air guide plate 41 forms an extension of the fourth air duct wall 34, so that the air outlet is only opened toward the front part, and the airflows blown by the first air supply duct and the second air supply duct are blown forward at the same time.

[0107] The indoor air conditioner unit 20 of this embodiment can have a preset long-distance cooling air supply mode. In the long-distance cooling air supply mode, the first air guide plate 41 of the indoor air conditioner unit 20 is in a position to close the air outlet and the second air guide plate 42 is open, so that the air outlet is only opened toward the front part, and the airflows blown by the first air supply duct and the second air supply duct are blown forward at the same time. At the same time, the indoor air conditioner unit 20 also controls the operation of the heat exchanger 26, specifically, controls the first heat exchange section 262 to work and the second heat exchange section 264 not to work, so that the first air supply duct blows a cooling airflow carrying coldness and the second air supply duct blows an ambient airflow with a temperature close to the room temperature.

[0108] The second air supply duct is located below the first air supply duct in height, so the upper layer of the mixed air flow blown out of the air outlet is mainly cooling air flow, and the lower layer is mainly ambient air flow.

[0109] Since the cold air generated by the air conditioner has a high density, it naturally tends to flow downward. This physical characteristic causes the cold to easily accumulate downward. The ambient airflow blown out from the air outlet is located below the refrigeration airflow, and continues to flow forward with the sinking cold in the refrigeration airflow, so that more cold is carried by the ambient airflow and the heat exchange airflow to a location far away from the indoor air conditioner unit 20, and avoids the cold from being accumulated downward in advance, thereby preventing the temperature of the area near the indoor air conditioner unit 20 from being too low.

[0110] The indoor unit 20 of the air conditioner of this embodiment can further control the rotation speed of the second cross-flow fan 24 to be greater than the rotation speed of the first cross-flow fan 23, thereby further improving the flow rate of the ambient airflow and the effect of carrying cold air.

[0111] Correspondingly, the indoor unit 20 of the air conditioner in this embodiment may also have a preset strong cooling air supply mode, that is, on the basis of controlling the first air guide plate 41 of the indoor unit 20 of the air conditioner to be in a position to close the air outlet and the second air guide plate 42 to be open, the first heat exchange section 262 and the second heat exchange section 264 of the heat exchanger 26 are controlled to work, so that the first air supply duct and the second air supply duct blow all cooling airflow to the air outlet.

[0112] In some alternative embodiments, the air conditioner indoor hanger 20 further includes a third air guide plate 43 .

[0113] The third air guide plate 43 is laterally arranged between the first end of the second air duct wall 32 and the air outlet; the third air guide plate 43 is configured so that when it is in a preset air guiding position, the rear end of the third air guide plate 43 is close to the first end of the second air duct wall 32, and the plate surface of the third air guide plate 43 is parallel to the air guiding direction of the second air duct wall 32 at the first end.

[0114] refer to Figure 2 As shown, the third air guide plate 43 of this embodiment is Figure 2 In the preset wind guiding position shown, the plate surface is parallel to the wind guiding direction of the second air duct wall 32 at the first end and close to the first end of the second air duct wall 32 , so that the plate surface of the third air guiding plate 43 forms an extension of the second air duct wall 32 .

[0115] refer to Figure 4 As shown, the third air guide plate 43 can rotate at the position inside the air outlet when the indoor air conditioner 20 is in any working mode, so as to change the air outlet direction at the air outlet. It can be understood that when the third air guide plate 43 reciprocates, the indoor air conditioner 20 can achieve the effect of sweeping air up and down. When the third air guide plate 43 is in the preset air guide position, it can also achieve the effect of separating the airflow of the first air supply duct and the second air supply duct from top to bottom to prevent the airflow from mixing.

[0116] In some alternative embodiments, when the third air guide plate 43 is in a preset air guide position, the rotation axis Q3 of the third air guide plate 43 is located near the upper side of the middle of itself.

[0117] For a way to determine the middle position of the third air guide plate 43, refer to the first air guide plate 41 . Figure 5 yes Figure 2 Another schematic diagram of the air conditioner indoor hanger 20 shown. Reference Figure 5 As shown, the third air guide plate 43 of the present embodiment can be rotated to a position where one end is close to the first air duct wall 31, and the second air guide plate 42 can also be rotated to a position where the plate surface extends longitudinally, thereby cooperatively separating the front side of the air outlet from the first air supply duct and the second air supply duct, so that the airflow blown out of the first air supply duct and the second air supply duct is blocked from the front and blown obliquely downward.

[0118] refer to Figure 5 As shown, the indoor air conditioner unit 20 of this embodiment can also have a preset short-distance heating and air supply mode. In the short-distance heating and air supply mode, the third air guide plate 43 of the indoor air conditioner unit 20 rotates to one end close to the first air duct wall 31 and the plate surface tilts forward and downward, and the first air guide plate 41 rotates to tilt downward or forward and downward. The second air guide plate 42 rotates to one end close to the bottom surface of the housing 21, so that the first air supply duct and the second air supply duct can only discharge air obliquely downward from the lower part of the air outlet.

[0119] Since the hot air generated by the air conditioner has a low density, it naturally tends to flow upwards. This physical property causes heat to easily accumulate upwards. The indoor air conditioner unit 20 of this embodiment sets a close-range heating and air supply mode, controls the rotation of the three air guide plates, and makes the air outlet direction of the indoor air conditioner unit 20 basically face directly downward, so that the heating air flow can be blown more to a lower place, thereby improving the close-range heating efficiency of the indoor air conditioner unit 20 when the user needs heating, without waiting for the room temperature to rise overall.

[0120] In some optional embodiments, when the third air guide plate 43 is in the preset air guide position, the distance between the rotation axis Q3 of the third air guide plate 43 and the front end of the third air guide plate 43 is equal to or slightly greater than the distance between the rotation axis Q3 of the third air guide plate 43 and the first air duct wall 31, so that when the indoor air conditioner unit 20 is in the close-range heating and air supply mode, the end of the third air guide plate 43 can be close to or abut against the surface of the first air duct wall 31. The "slightly greater than" mentioned here can generally be specifically greater than 1:1 and less than or equal to 105:100.

[0121] In some optional embodiments, the ratio of the distance D1 between the lower side of the air outlet and the upper side of the air outlet in the front-to-back direction to the distance D2 between the upper side of the air outlet and the rear side of the shell 21 is greater than or equal to 1:3.

[0122] refer to Figure 1 As shown, the distance D1 between the lower side of the air outlet of the indoor air conditioner unit 20 of this embodiment and the upper side of the air outlet in the front-to-back direction is the distance between the upper and lower sides of the air outlet projected on the horizontal plane, and the distance D2 between the upper side of the air outlet and the rear side of the housing 21 can generally be the front-to-back width of the housing 21 of the indoor air conditioner unit 20. The ratio of the distance D1 between the lower side of the air outlet and the upper side of the air outlet in the front-to-back direction and the distance D2 between the upper side of the air outlet and the rear side of the housing 21 of this embodiment is greater than 1:3, so that the air outlet has a larger opening and better matches with the first air guide plate 41 and the second air guide plate 42.

[0123] In some alternative embodiments, the ratio of the distance D1 of the lower side of the air outlet to the upper side of the air outlet in the front and rear direction to the distance D2 of the upper side of the air outlet and the rear side of the housing 21 may be further greater than or equal to 1:2.

[0126] The air conditioner 10 is used to adjust the indoor air, specifically, it can include one or more functions such as adjusting the temperature, humidity, air quality of the air, humidifying, dehumidifying, introducing fresh air, etc. It can be understood that in terms of temperature adjustment, the indoor air conditioner 20 of this embodiment can have other air supply modes not described in addition to some of the air supply modes already listed.
