For those skilled in the art, the specific meanings of these terms in the embodiments of the present disclosure can be understood according to the specific circumstances.

[0045] In addition, the terms "set", "connected", "fixed" should be broadly understood. For example, "connected" can be fixedly connected, detachably connected, or integrally configured; can be mechanically connected, or electrically connected; can be directly connected, or indirectly connected through an intermediate medium, or internal communication between two devices, elements or components.

[0047] In the embodiments of the present disclosure, the character " / " represents a "or" relationship between the objects before and after it. For example, A / B represents: A or B.

[0048] The term "and / or" is a description of the association between objects, which means that there can be three relationships. For example, A and / or B, which means: A or B, or, A and B, the three relationships.

[0049] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0050] In combination Figures 1-12 As shown, the embodiments of the present disclosure provide a shell assembly for an indoor unit of an air conditioner.

[0051] The shell assembly includes a shell 100. The shell 100 defines an air duct 11, and is provided with an air inlet and an air outlet 12 which are in communication with the air duct.

[0052] The indoor unit further comprises a volute, an indoor heat exchanger and a fan 60. The volute and the indoor heat exchanger are arranged in the air duct. The volute defines a mounting cavity. The fan 60 is arranged in the mounting cavity. Under the action of the fan 60, air enters from the air inlet, exchanges heat with the indoor heat exchanger, and then flows out through the air outlet, thereby realizing normal operation of the air conditioner.

[0053] As shown in Figure 1 and Figure 2 , the inner wall surface of the side wall of the air outlet 12 is provided with a groove 15.

[0054] Before the groove 15 is arranged, the cold air flowing out of the air outlet in the cooling mode meets the indoor hot air at the air outlet, resulting in condensation on the outer surface of the shell 100. The arrangement of the groove 15 changes the meeting area of the cold air and the hot air, so that the meeting area moves to the groove 15. In this way, condensation mainly occurs at the groove 15, avoiding the influence of condensation on the outer surface of the shell 100. Moreover, the arrangement of the groove 15 has little impact on the structure of the shell 100, so that the molding cost of the shell 100 is low.

[0055] Optionally, as shown in Figure 11 , the side wall of the air outlet comprises a first side wall 121 and a second side wall 122. The second side wall is arranged opposite to the first side wall; wherein the inner wall surface of the first side wall and the second side wall is provided with a groove 15.

[0056] The groove 15 is arranged on the inner wall surface of the first side wall and the second side wall, so that the meeting place of the cold air flowing through the first side wall and the second side wall with the indoor hot air moves to the groove 15 arranged respectively, so that there is no condensation on the outer surface of the shell 100 close to the first side wall and the second side wall.

[0057] The first side wall and the second side wall both extend along the up-down direction. Taking the air conditioner as an example, the first side wall and the second side wall can be respectively Figure 11 the left side wall and the right side wall of the air outlet of the cabinet air conditioner.

[0058] The groove 15 arranged on the first side wall extends along the length direction of the first side wall, and the groove 15 arranged on the second side wall extends along the length direction of the second side wall.

[0059] Optionally, as shown in Figure 2 , the groove wall of the groove 15 comprises a first groove wall 151 and a second groove wall 152. One end of the first groove wall 151 is connected with the side wall of the air duct, and the connection forms a first fold angle 13; the second groove wall 152 is connected with the other end of the first groove wall 151, and the connection forms a second fold angle 14.

[0060] The groove wall of the groove 15 comprises a first groove wall 151 and a second groove wall 152, and the first groove wall 151 is located between the side wall of the air duct and the second groove wall 152. The first fold angle 13 changes the flow direction of the cold air flowing out of the air outlet, avoids the cold air flowing to the outer surface of the shell 100, and causes the cold air and the hot air existing at the groove 15 to converge, thereby generating condensation at the groove 15.

[0061] The other end of the first groove wall 151 is connected with the second groove wall 152, and the connection forms a second fold angle 14. The second fold angle 14 is formed so that the first groove wall 151 and the second groove wall 152 form the groove 15, so that the condensation can be concentrated at the groove 15, and the condensation is avoided from being generated at the outer surface of the shell 100.

[0062] Optionally, the length L of the first groove wall 151 is greater than or equal to 8 mm, for example, 8 mm, 10 mm, 12 mm, etc.

[0063] The other end of the second groove wall 152 is connected with the outer surface of the shell 100, and the connection forms a third fold angle 17. When the length L of the first groove wall 151 is less than 8 mm, the size of the groove 15 is small, and the cold air flowing out of the air outlet still flows to the third fold angle 17, causing condensation to be generated at the third fold angle 17, which affects the appearance of the shell 100.

[0064] Optionally, a circular arc transition is adopted at the first fold angle 13.

[0065] The first fold angle 13 adopts a circular arc design. The smooth surface of the circular arc allows the air flowing out of the air outlet to flow along the circular arc wall, which reduces the resistance of the first fold angle 13 to the air volume, reduces the loss of air volume, improves energy efficiency, and reduces the noise of the air outlet.

[0066] Optionally, as shown in Figure 2 、 Figure 7 and Figure 8 , the shell assembly further comprises a water blocking rib 16, which is located in the groove 15 and is arranged on the first groove wall 151.

[0067] The water blocking rib 16 is a protruding structure arranged on the surface of the first groove wall 151. The water blocking rib 16 extends along the width of the first groove wall 151. In this way, the arrangement of the water blocking rib 16 can block the condensation from flowing downward directly, and can visually optimize the appearance influence caused by the condensation.

[0068] The water blocking rib 16 can be designed as a simple structure to reduce the difficulty of molding and ensure the molding quality. For example, the water blocking rib 16 can be designed as a long strip shape.

[0069] Optionally, the water blocking rib 16 extends in the direction from the other end to the one end of the first groove wall 151.

[0070] The water-blocking rib 16 extends from the connection point (i.e., the first bend 13) between the first trough wall 151 and the air duct towards the second trough wall 152, forming a horizontally arranged long strip structure that effectively blocks the downward flow of condensation.

[0071] It is understandable that the water-retaining rib 16 can also be set at an angle. In the case of an angled setting, a water-receiving groove can be further provided on the housing 100, so that the condensation flowing down from the water-retaining rib 16 can slide into the water-receiving groove.

[0072] There are multiple water-retaining ribs 16, such as... Figure 7 and Figure 8 As shown, multiple water-blocking ribs 16 are arranged along the length of the air outlet (e.g., Figure 7 Set them sequentially in the top and bottom directions.

[0073] The multiple water-blocking ribs 16 are designed so that the condensation generated along the length of the air outlet can be received by the water-blocking ribs 16, preventing the condensation from dripping directly downwards.

[0074] Multiple water-blocking ribs 16 are arranged sequentially along the length of the first groove wall 151, and there is a gap between adjacent water-blocking ribs 16. The gap between adjacent water-blocking ribs 16 is evenly distributed, and the adjacent gap M satisfies 3mm≤M≤8mm, for example, M equals 3mm, 5mm, 7mm or 8mm.

[0075] When M is less than 3mm, the gap between two adjacent water-blocking ribs 16 is smaller, and the amount of condensation that can be borne between two adjacent water-blocking ribs 16 is effective. When the amount of condensation is large, it will still drip from the water-blocking ribs 16. When M is greater than 8mm, the number of water-blocking ribs 16 is smaller, and when the amount of condensation exceeds the bearing capacity of the water-blocking ribs 16, it will still drip from the water-blocking ribs 16.

[0076] Optionally, the water-blocking rib 16 is connected to the inner wall surface of the side wall of the air duct, and the connection is made with a rounded transition.

[0077] The rounded transition can reduce the impact on the air outlet, making the setting of the water baffle 16 have a smaller impact on the airflow at the air outlet, and can also reduce the generation of noise.

[0078] The indoor unit also includes air distribution ribs 20.

[0079] The air distribution rib 20 is installed inside the air duct and divides the air duct into a first sub-air duct 111 and a second sub-air duct 112, for example, Figure 1As shown, the air distribution rib 20 is arranged at the air outlet and divides the air outlet into a first sub-air outlet 123 and a second sub-air outlet 124. The first sub-air duct 111 is in communication with the first sub-air outlet 123, and the heat exchange air blown out through the first sub-air duct 111 is blown out through the first sub-air outlet 123. The second sub-air duct 112 is in communication with the second sub-air outlet 124, and the heat exchange air blown out through the second sub-air duct 112 is blown out through the second sub-air outlet 124.

[0080] As shown, Figure 3 the air distribution rib 20 includes a first side wall surface 201 and a second side wall surface 202. The first side wall surface 201 constitutes at least part of the duct wall of the first sub-air duct 111, and the second side wall surface 202 constitutes at least part of the duct wall of the second sub-air duct 112.

[0081] The first side wall surface 201 is provided with a first air guide portion 2011 for guiding the airflow flowing through the first side wall surface 201 to flow toward the axis of the first sub-air duct 111, and / or the second side wall surface 202 is provided with a second air guide portion 2021 for guiding the airflow flowing through the second side wall surface 202 to flow toward the axis of the second sub-air duct 112.

[0082] One end of the first side wall surface 201 is connected to one end of the second side wall surface 202 and forms an included angle, as shown, Figure 3 the included angle is an acute angle, the other end of the first side wall surface 201 extends away from the second side wall surface 202, the other end of the second side wall surface 202 extends away from the first side wall surface 201, and the air distribution rib 20 further includes a connecting section 203 connected between the other end of the first side wall surface 201 and the other end of the second side wall surface 202.

[0083] The first side wall surface 201 and the shell 100 define the first sub-air duct 111, and the second side wall surface 202 and the shell 100 define the second sub-air duct 112.

[0084] As shown, Figure 1 , Figure 4 and Figure 5 the first side wall surface 201 is provided with a first air guide portion 2011 for guiding the airflow flowing through the first side wall surface 201 to flow toward the axis of the first sub-air duct 111, so that the heat exchange air flowing out of the first sub-air duct 111 flows toward the axis direction of the first sub-air duct 111, i.e., the heat exchange air flows away from the outer surface of the air distribution rib 20 (i.e., the outer surface of the connecting section 203), avoiding the cold and hot intersection of the heat exchange air and the indoor air on the outer surface of the connecting section 203, thereby avoiding the condensation on the outer surface of the air distribution rib 20.

[0085] The second side wall surface 202 is provided with a second air guide part 2021 for guiding the air flow passing through the second side wall surface 202 to flow towards the axis of the second sub-air duct 112, so that the heat exchange air flowing out of the second sub-air duct 112 flows towards the axis of the second sub-air duct 112, i.e. the heat exchange air flows towards the direction away from the outer surface of the air distribution rib 20 (i.e. the outer surface of the connecting section 203), avoiding the cold and hot air exchange on the outer surface of the connecting section 203, thereby avoiding the condensation on the outer surface of the air distribution rib 20.

[0086] Optionally, the first side wall surface 201 is provided with a first bend 2012, and the first air guide part 2011 comprises the first bend 2012; and / or the second side wall surface 202 is provided with a second bend 2022, and the second air guide part 2021 comprises the second bend 2022.

[0087] The first bend 2012 is located in the first sub-air duct 111, and the first bend 2012 hinders the passing heat exchange air, so that the flow direction of the heat exchange air changes, in other words, the first bend 2012 has a guiding effect on the heat exchange air, so that the heat exchange air flowing out of the first sub-air duct 111 flows towards the axis of the first sub-air duct 111, i.e. the heat exchange air flows towards the direction away from the outer surface of the air distribution rib 20, avoiding the condensation on the outer surface of the connecting section 203.

[0088] The second bend 2022 is located in the second sub-air duct 112, and the second bend 2022 hinders the passing heat exchange air, so that the flow direction of the heat exchange air changes, in other words, the second bend 2022 has a guiding effect on the heat exchange air, so that the heat exchange air flowing out of the second sub-air duct 112 flows towards the axis of the second sub-air duct 112, i.e. the heat exchange air flows towards the direction away from the outer surface of the air distribution rib 20, avoiding the condensation on the outer surface of the connecting section 203.

[0089] Optionally, as shown in Figure 4 and Figure 5 , the first side wall surface 201 comprises a first sub-side wall surface 2013 and a second sub-side wall surface 2014 arranged in sequence along the flow direction of the air flow (heat exchange air), the first sub-side wall surface 2013 and the second sub-side wall surface 2014 are connected and the connection forms the first bend 2012, and the first bend 2012 protrudes from the second sub-side wall surface 2014 towards the axis of the first sub-air duct 111; and / or the second side wall surface 202 comprises a third sub-side wall surface 2023 and a fourth sub-side wall surface 2024 arranged in sequence along the flow direction of the air flow (heat exchange air), the third sub-side wall surface 2023 and the fourth sub-side wall surface 2024 are connected and the connection forms the second bend 2022, and the second bend 2022 protrudes from the fourth sub-side wall surface 2024 towards the axis of the second sub-air duct 112.

[0090] The first bend 2012 protrudes from the second sub-side wall surface 2014 towards the axis direction of the first sub-air duct 111, so the first sub-side wall surface 2013 and the second sub-side wall surface 2014 are not in the same plane, i.e. the first sub-side wall surface 2013 and the second sub-side wall surface 2014 are staggered, the distance between the first sub-side wall surface 2013 and the axis of the first sub-air duct 111 is smaller than the distance between the second sub-side wall surface 2014 and the axis of the first sub-air duct 111, so the heat exchange air flows out along the length direction of the first sub-side wall surface 2013, the distance between the heat exchange air and the second sub-side wall surface 2014 is larger, so the distance between the heat exchange air and the connecting section 203 is larger, and no condensation is generated on the outer surface of the connecting section 203. The first bend 2012 protrudes from the first sub-side wall surface 2013 or does not protrude from the first sub-side wall surface 2013 towards the axis direction of the first sub-air duct 111.

[0091] The second bend 2022 protrudes from the fourth sub-side wall surface 2024 towards the axis direction of the second sub-air duct 112, so the third sub-side wall surface 2023 and the fourth sub-side wall surface 2024 are not in the same plane, i.e. the third sub-side wall surface 2023 and the fourth sub-side wall surface 2024 are staggered, the distance between the third sub-side wall surface 2023 and the axis of the second sub-air duct 112 is smaller than the distance between the fourth sub-side wall surface 2024 and the axis of the second sub-air duct 112, so the heat exchange air flows out along the length direction of the third sub-side wall surface 2023, the distance between the heat exchange air and the fourth sub-side wall surface 2024 is larger, so the distance between the heat exchange air and the connecting section 203 is larger, and no condensation is generated on the outer surface of the connecting section 203. The second bend 2022 protrudes from the third sub-side wall surface 2023 or does not protrude from the third sub-side wall surface 2023 towards the axis direction of the second sub-air duct 112.

[0092] Moreover, at a low rotating speed of the air conditioner, the condensation generated at the intersection of the heat exchange air and the indoor air can be eliminated.

[0093] Optionally, as shown in Figure 4 The first side wall surface 201 further includes a first transition wall surface 2015, which is arranged between the first sub-side wall surface 2013 and the second sub-side wall surface 2014, and the connection between the first transition wall surface 2015 and the first sub-side wall surface 2013 forms a first corner 2016, the first corner 2016 protrudes from the first transition wall surface 2015 towards the axis direction of the first sub-air duct 111, the connection between the first transition wall surface 2015 and the second sub-side wall surface 2014 forms a second corner 2017, and the first bend 2012 includes the first corner 2016.

[0094] The first corner 2016 protrudes from the first transition wall 2015 along the axis of the first sub-duct 111. That is, the distance between the first corner 2016 and the axis of the first sub-duct 111 is less than the distance between the first transition wall 2015 and the axis of the first sub-duct 111. This allows the flow direction of the heat exchange air to be changed at the first corner 2016, and also creates a gap between the heat exchange air and the second sub-side wall 2014. The first corner 2016 and the second corner 2017 are located at opposite ends of the first transition wall 2015. The design of the first transition wall 2015 makes the first side wall 201 smoother overall, reducing airflow loss and avoiding potential noise issues.

[0096] The third corner protrudes from the second transition wall in the direction of the axis of the second sub-duct 112. That is, the distance between the third corner and the axis of the second sub-duct 112 is less than the distance between the second transition wall and the axis of the second sub-duct 112. This allows the flow direction of the heat exchange air to be changed at the third corner, and also creates a gap between the heat exchange air and the fourth sub-side wall 2024.

The first protrusion increases the height of the first bend 2012 protruding towards the axis of the first sub-air duct 111, and also enhances the effect of changing the direction of the heat exchange air.

[0099] The airflow of the heat exchange air changes direction when passing through the second protrusion 2025, and flows out along the length direction of the third sub-side wall surface 2023.

[0102] The fourth protrusion 304 changes the flow direction of the heat exchange air in the second sub-air duct 112, so that the airflow of the heat exchange air changes direction when passing through the fourth protrusion 304, and flows out along the outer surface of the fourth protrusion 304, thereby increasing the distance between the heat exchange air and the fourth sub-side wall surface 2024, and increasing the distance between the heat exchange air and the connecting section 203, so as to avoid condensation at the connecting section 203.

[0106] The fourth protrusion 304 is arranged between the third end 311 and the fourth end 312, and the distance between the fourth protrusion 304 and the third end 311 is less than or equal to half of the length of the second side wall surface 202, so that the heat exchange air flowing along the second side wall surface 202 can be affected by the fourth protrusion 304 as early as possible, so that the flow direction changes, and when the heat exchange air continues to flow over the fourth protrusion 304, it will further deviate from the connecting section 203, thereby increasing the distance between the heat exchange air and the connecting section 203, and avoiding the generation of condensation at the connecting section 203.

[0115] The air duct includes an upstream air duct and a downstream air duct connected in sequence along the airflow direction, and the air outlet is connected with the downstream air duct; the air distribution rib 20 is arranged in the downstream air duct and separates the downstream air duct into the first sub-air duct 111 and the second sub-air duct 112; the air distribution grid 40 is arranged in the upstream air duct and is used to adjust the air volume flowing into the first sub-air duct 111 and the second sub-air duct 112 through the upstream air duct.

[0116] By adjusting the air volume flowing into the first sub-air duct 111 and the second sub-air duct 112 through the air distribution grid 40, the air volume discharged through the first sub-air duct 111 and the second sub-air duct 112 is adjusted to further improve the air supply comfort.

[0117] By adjusting the air volume discharged through the first sub-air duct 111 and the second sub-air duct 112 by using the air distribution grid 40, it is not necessary to adjust the air duct profile or the change of the air duct profile is small, in other words, the adjustment of the air volume of the first sub-air duct 111 and the second sub-air duct 112 can be realized without changing the air duct profile or with small change of the air duct profile, and the adjustment method is simple and low in cost.

[0118] Optionally, as shown, Figure 1As shown, the air distribution grille 40 comprises a first grille 401, which is arranged corresponding to the air distribution fin 20 and extends along the airflow direction, and separates the upstream air duct into a third sub-air duct 113 and a fourth sub-air duct 114, the third sub-air duct 113 being in communication with the first sub-air duct 111, and the fourth sub-air duct 114 being in communication with the second sub-air duct 112.

[0119] The first grille 401 is arranged in the upstream air duct, and separates the upstream air duct into the third sub-air duct 113 and the fourth sub-air duct 114, the third sub-air duct 113 corresponding to the first sub-air duct 111, and the fourth sub-air duct 114 corresponding to the second sub-air duct 112. When the heat exchange air flows out of the air duct and meets the first grille 401, the heat exchange air is divided into two parts by the first grille 401, one part flows through the third sub-air duct 113 into the first sub-air duct 111, and the other part flows through the fourth sub-air duct 114 into the second sub-air duct 112. Therefore, the length, inclination or other parameters of the first grille 401 can be adjusted to adjust the air volume flowing into the first sub-air duct 111 and the second sub-air duct 112, and improve the air supply comfort of the air conditioner.

[0120] Optionally, the air distribution grille 40 further comprises a second grille 402 and / or a third grille 403.

[0121] The second grille 402 is arranged in the third sub-air duct 113 and extends along the airflow direction, and divides the third sub-air duct 113 into two spaces. When the airflow passes through the third sub-air duct 113, the airflow can be divided into two streams by the second grille 402. Therefore, the length, inclination or other parameters of the second grille 402 can be adjusted to adjust the air volume flowing out of the first sub-air duct 111, so as to adjust the air volume flowing out of the first sub-air duct 111. The third grille 403 is arranged in the fourth sub-air duct 114 and extends along the airflow direction, and divides the fourth sub-air duct 114 into two spaces.

[0123] The first grid 401 is arranged between the second grid 402 and the third grid 403, and the arrangement of the first grid 401 divides the upstream air duct into the third sub-air duct 113 and the fourth sub-air duct 114. When the lengths of the first grid 401, the second grid 402 and the third grid 403 are the same, the air resistance of the airflow in the upstream air duct is increased, and the air volume is reduced. The first grid 401 is used to roughly divide the airflow into two parts, and coarsely adjust the air volume of the first sub-air duct 111 and the second sub-air duct 112. The second grid 402 and the third grid 403 are respectively used to finely adjust the air volume in the first sub-air duct 111 and the second sub-air duct 112. Therefore, the length of the first grid 401 is greater than the length of the second grid 402, and the length of the first grid 401 is greater than the length of the third grid 403.

The second air duct wall 116 is arranged opposite to the first air duct wall 115 and constitutes at least part of the air duct wall of the fourth sub-air duct 114. The first air duct wall 115 protrudes towards a direction away from the air duct axis, and the second air duct wall 116 protrudes towards a direction close to the air duct axis.

[0125] The first air duct wall 115 and the first side wall surface 201 define the first sub-air duct 111. The first air duct wall 115 and the first grid 401 define the third sub-air duct 113. The second air duct wall 116 and the second side wall surface 202 define the second sub-air duct 112. The second air duct wall 116 and the first grid 401 define the fourth sub-air duct 114.

[0126] The first air duct wall 115 protrudes towards a direction away from the air duct axis, so as to increase the width of the first sub-air duct 111 and the third sub-air duct 113, and increase the air volume of the first sub-air duct 111 and the second sub-air duct 112. The second air duct wall 116 protrudes towards a direction close to the air duct axis, so as to reduce the width of the second sub-air duct 112 and the fourth sub-air duct 114, and increase the air volume of the second sub-air duct 112 and the fourth sub-air duct 114.

[0127] Optionally, the second grid 402 is in a straight line type. The number of the second grid 402 is multiple. The multiple second grids 402 are arranged in sequence along the width direction of the third sub-air duct 113. Along the direction close to the first air duct wall 115, the inclination angle of the second grid 402 is increased and / or the length of the second grid 402 is increased.

[0128] The second grating 402 is arranged in a straight line, and is inclined towards the first air duct wall 115 along the flow direction of the air flow, so as to guide the air flow towards the first air duct wall 115. The straight-line arrangement of the second grating 402 can improve the smoothness and uniformity of the air flow, and is beneficial to uniform air outlet of the first sub-air outlet 123, and meets the use requirements of the user.

[0129] The plurality of second gratings 402 are sequentially arranged along the width direction of the third sub-air duct 113, and the inclination angle of the second grating 402 increases along the direction close to the first air duct wall 115, that is, the plurality of second gratings 402 are not parallel, the inclination angle of the second grating 402 close to the first air duct wall 115 is large, and the inclination angle of the second grating 402 away from the first air duct wall 115 is small, so as to guide the air flow towards the first air duct wall 115 and increase the air outlet range of the first sub-air outlet 123.

[0130] Optionally, as shown in Figure 6 The third grating 403 includes a first grating segment 4031 and a second grating segment 4032 sequentially arranged along the flow direction of the air flow, the first grating segment 4031 is connected with the second grating segment 4032, and the second grating segment 4032 is located on the side of the first grating segment 4031 towards the second air duct wall 116.

[0131] The third grating 403 is not straight, and includes a first grating segment 4031 and a second grating segment 4032 sequentially arranged along the flow direction of the air flow, the distance between the first grating segment 4031 and the second air duct wall 116 is greater than the distance between the second grating segment 4032 and the second air duct wall 116, so as to guide the air flow towards the second air duct wall 116 and increase the air outlet range of the second sub-air outlet 124. The arrangement of the first grating segment 4031 and the second grating segment 4032 can adjust the air direction, so that the air flow passes through the fourth sub-air duct 114 more smoothly, reduces the obstruction to the air outlet, can improve the air outlet performance and reduce the energy consumption, and can also avoid the air outlet directly blowing on the user, reduces the discomfort, and improves the comfort.

[0132] Optionally, the number of the third gratings 403 is a plurality, and the plurality of third gratings 403 are sequentially arranged along the width direction of the fourth sub-air duct 114, and the length of the third grating 403 decreases along the direction close to the second air duct wall 116. In other words, among the plurality of third gratings 403, the length of the third grating 403 away from the second air duct wall 116 is large, and the length of the third grating 403 close to the second air duct wall 116 is small.

[0133] The length of the third grating 403 will affect the air outlet amount, and in the case that other parameters of the third grating 403 are the same, the greater the length of the third grating 403, the greater the air resistance, and the smaller the length, the smaller the air resistance. Therefore, along the direction close to the second air duct wall 116, the length of the third grating 403 gradually decreases, which can increase the end of the second sub-air outlet 124 away from the first sub-air outlet 123 (that isFigure 1 The air volume of the first sub-air outlet 123 and the second sub-air outlet 124 is adjusted, so that the air volume of the first sub-air outlet 123 and the second sub-air outlet 124 is more uniform.

[0136] The driving device can adjust the parameters (including the inclination angle and the distance from the adjacent air distribution grille 40) of each air distribution grille 40 respectively, or can synchronously adjust the parameters of at least two air distribution grilles 40.

[0137] When the driving device needs to synchronously adjust the parameters of at least two air distribution grilles 40, a connecting rod can be arranged between the air distribution grilles 40, the driving device is connected with the connecting rod, and the driving device drives the connecting rod to move, so as to adjust the parameters of the multiple air distribution grilles 40 through the connecting rod.

By adjusting the position of the air deflector 50, the direction of the air outlet is changed, the air outlet direction of the indoor unit is diversified, the different use requirements of the user can be met, and the experience of the user is improved. When the air conditioner is turned off, the air deflector 50 closes the air outlet, which can prevent dust from entering the air outlet and has a certain protective effect and dustproof effect.

[0142] In the closed position, the air deflector 50 is located outside the groove 15, so that the air deflector 50 shields the groove 15, avoiding the groove 15 affecting the appearance of the shell 100.
