[0041] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure.

[0044] Furthermore, the terms "disposed," "connected," and "fixed" should be interpreted broadly. For example, "connected" can mean a fixed connection, a removable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediary, or an internal connection between two devices, elements, or components.

[0045] Unless otherwise stated, the term "plurality" means two or more.

[0046] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B means: A or B.

[0047] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0049] Combine Figure 1-12 As shown, an embodiment of the present disclosure provides a housing assembly for an indoor unit of an air conditioner.

[0050] The housing assembly includes a housing 100. The housing 100 defines an air outlet duct 11 and is provided with an air inlet and an air outlet 12 communicating with the air outlet duct.

[0051] The indoor unit also includes a volute, an indoor heat exchanger, and a fan 60. Both the volute and the indoor heat exchanger are located within the air duct. The volute defines a mounting cavity within which the fan 60 is located. Fan 60 draws air in through the air inlet, exchanges heat with the indoor heat exchanger, and then flows out through the air outlet, ensuring normal operation of the air conditioner.

[0052] like Figure 1and Figure 2 As shown, a groove 15 is provided on the inner wall surface of the side wall of the air outlet 12 .

[0053] Without groove 15, in cooling mode, the cold air flowing out of the air outlet meets the hot indoor air at the outlet, causing condensation on the outer surface of housing 100. The provision of groove 15 shifts the intersection of cold and hot air to the groove 15, where condensation primarily forms, preventing it from affecting the outer surface of housing 100. Furthermore, the provision of groove 15 requires minimal structural changes to housing 100, reducing the cost of manufacturing housing 100.

[0054] Alternatively, as Figure 11 As shown, the side wall of the air outlet includes 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 surfaces of the first side wall and the second side wall are both provided with a groove 15.

[0055] Grooves 15 are provided on the inner wall surfaces of the first side wall and the second side wall, so that the cold air flowing through the first side wall and the second side wall and the indoor hot air move to the intersection of their respective grooves 15, so that no condensation will be generated on the outer surface of the shell 100 near the first side wall and the second side wall.

[0056] The first side wall and the second side wall both extend in the up-down direction. Taking the air conditioner as a cabinet as an example, the first side wall and the second side wall can be respectively Figure 11 The left and right walls of the center air outlet.

[0057] The groove 15 provided on the first side wall extends along the length direction of the first side wall, and the groove 15 provided on the second side wall extends along the length direction of the second side wall.

[0058] Alternatively, as Figure 2 As shown, the groove wall of the groove 15 includes a first groove wall 151 and a second groove wall 152. One end of the first groove wall 151 is connected to the side wall of the air duct to form a first angle 13; the second groove wall 152 is connected to the other end of the first groove wall 151 to form a second angle 14.

[0059] The groove 15 includes a first groove wall 151 and a second groove wall 152. The first groove wall 151 is located between the side wall of the air duct and the second groove wall 152. The first bend 13 changes the flow direction of the cold air flowing out of the air outlet, preventing the cold air from flowing to the outer surface of the housing 100. This causes the cold air to intersect with the hot air in the groove 15, thereby generating condensation in the groove 15.

[0060] The other end of the first groove wall 151 is connected to the second groove wall 152 and a second fold angle 14 is formed at the connection. The formation of the second fold angle 14 allows the first groove wall 151 and the second groove wall 152 to form a groove 15, so that condensation can be concentrated in the groove 15, avoiding condensation from being generated on the outer surface of the shell 100.

[0061] 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.

[0062] The other end of the second groove wall 152 is connected to the outer surface of the shell 100 and a third corner 17 is formed at the connection. When the length L of the first groove wall 151 is less than 8 mm, the size of the groove 15 is smaller, and the cold air flowing out of the air outlet will still flow to the third corner 17, resulting in condensation at the third corner 17, affecting the appearance of the shell 100.

[0063] Optionally, an arc transition is adopted at the first corner 13 .

[0064] The first corner 13 adopts an arc design with a smooth arc surface, so that when the wind flowing out of the air outlet flows along the arc wall, the resistance of the first corner 13 to the air outlet can be reduced, the loss of air volume can be reduced, energy efficiency can be improved, and the air outlet noise can be reduced.

[0065] Alternatively, as Figure 2 、 Figure 7 and Figure 8 As shown, the housing assembly further includes a water retaining rib 16 , which is located in the groove 15 and disposed on the first groove wall 151 .

[0066] The water retaining rib 16 is a raised structure provided on the surface of the first groove wall 151 and extends along the width of the first groove wall 151 . The setting of the water retaining rib 16 can prevent condensation from flowing directly downward, and visually optimize the appearance impact caused by the condensation.

[0067] The water retaining rib 16 can be designed to have a simple shape to reduce the difficulty of demoulding and ensure the molding quality. For example, the water retaining rib 16 can be designed to have a long strip shape.

[0068] Optionally, the water retaining rib 16 extends along the direction from the other end to the one end of the first groove wall 151 .

[0069] The water retaining rib 16 extends along the connection between the first groove wall 151 and the air duct (ie, the first corner 13 ) toward the second groove wall 152 , forming a transversely arranged long strip structure, effectively preventing condensation from flowing downward.

[0070] It is understood that the water retaining rib 16 can also be tilted. In the case of a tilted arrangement, a water receiving trough can be further provided on the housing 100, and the condensation flowing down from the water retaining rib 16 can slide into the water receiving trough.

[0071] The number of water retaining ribs 16 is multiple, such as Figure 7 and Figure 8 As shown, multiple water retaining ribs 16 are arranged along the length direction of the air outlet (such as Figure 7 Set in sequence (up and down directions).

[0072] The arrangement of the plurality of water retaining ribs 16 ensures that the condensation generated along the length direction of the air outlet can be received by the water retaining ribs 16 there, thereby preventing the condensation from dripping directly downwards.

[0073] Multiple water retaining ribs 16 are arranged in sequence along the length direction of the first groove wall 151, and there is a spacing between adjacent water retaining ribs 16. The spacing between adjacent water retaining ribs 16 is evenly distributed, and the adjacent spacing M satisfies 3mm≤M≤8mm, for example, M is equal to 3mm, 5mm, 7mm or 8mm.

[0074] M is less than 3mm, so that the distance between two adjacent water retaining bars 16 is smaller, and the amount of condensation carried between the two adjacent water retaining bars 16 is effective. When the amount of condensation is large, it will still drip from the water retaining bars 16; M is greater than 8mm, resulting in a smaller number of water retaining bars 16. When the amount of condensation exceeds the carrying capacity of the water retaining bars 16, it will still drip from the water retaining bars 16.

[0075] Optionally, the water retaining rib 16 is connected to the inner wall surface of the side wall of the air duct and an arc transition is used at the connection.

[0076] The arc transition can reduce the impact on the air outlet, so that the setting of the water retaining rib 16 has less impact on the air flow of the air outlet, and can also reduce the generation of noise.

[0077] The indoor unit further includes air distribution ribs 20 .

[0078] The air dividing ribs 20 are provided in the air duct and divide the air duct into a first sub-air duct 111 and a second sub-air duct 112. Figure 1 As shown, the air dividing ribs 20 are provided at the air outlet, dividing the air outlet into a first sub-air outlet 123 and a second sub-air outlet. The first sub-air duct 111 is connected to the first sub-air outlet 123, and the heated air blown out of the first sub-air duct 111 is blown out through the first sub-air outlet 123. The second sub-air duct 112 is connected to the second sub-air outlet 124, and the heated air blown out of the second sub-air duct 112 is blown out through the second sub-air outlet 124.

[0079] like Figure 3 As shown, the air dividing 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 a portion of the air duct wall of the first sub-air duct 111 , and the second side wall surface 202 constitutes at least a portion of the air duct wall of the second sub-air duct 112 .

[0080] Among them, the first side wall surface 201 is provided with a first air guide portion 2011, which is used to guide 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, which is used to guide the airflow flowing through the second side wall surface 202 to flow toward the axis of the second sub-air duct 112.

[0081] One end of the first side wall surface 201 is connected to one end of the second side wall surface 202 and forms an angle, such as Figure 3 As shown, the angle is an acute angle, the other end of the first side wall surface 201 extends in a direction away from the second side wall surface 202, and the other end of the second side wall surface 202 extends in a direction away from the first side wall surface 201. The wind rib 20 also includes a connecting section 203, which is connected between the other end of the first side wall surface 201 and the other end of the second side wall surface 202.

[0082] The first side wall surface 201 and the housing 100 define a first sub-air duct 111 , and the second side wall surface 202 and the housing 100 define a second sub-air duct 112 .

[0083] like Figure 1 、 Figure 4 and Figure 5 As shown, the first side wall surface 201 is provided with a first air guide portion 2011, which is used to guide the airflow flowing through the first side wall surface 201 to flow toward the axis of the first sub-duct 111, so that the heat exchange air flowing out of the first sub-duct 111 will flow toward the axis of the first sub-duct 111, that is, the heat exchange air will flow in the direction away from the outer surface of the air dividing rib 20 (that is, the outer surface of the connecting section 203), avoiding the hot and cold intersection of the heat exchange air and the indoor air on the outer surface of the connecting section 203, thereby avoiding condensation on the outer surface of the air dividing rib 20.

[0084] The second side wall 202 is provided with a second air guide portion 2021, which is used to guide the airflow flowing through the second side wall 202 to flow toward the axis of the second sub-duct 112, so that the heat exchange air flowing out of the second sub-duct 112 will flow toward the axis of the second sub-duct 112, that is, the heat exchange air will flow in the direction away from the outer surface of the air dividing rib 20 (that is, the outer surface of the connecting section 203), avoiding the hot and cold intersection of the heat exchange air and the indoor air on the outer surface of the connecting section 203, thereby avoiding condensation on the outer surface of the air dividing rib 20.

[0085] Optionally, the first side wall surface 201 is provided with a first bend 2012 , and the first air guide portion 2011 includes the first bend 2012 ; and / or the second side wall surface 202 is provided with a second bend 2022 , and the second air guide portion 2021 includes the second bend 2022 .

[0086] The first bend 2012 is located in the first sub-duct 111. The first bend 2012 has an obstructive effect on the passing heat exchange air, which can change the flow direction of the heat exchange air. 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-duct 111 will flow toward the axial direction of the first sub-duct 111, that is, the heat exchange air will flow in the direction away from the outer surface of the air dividing rib 20, avoiding condensation on the outer surface of the connecting section 203.

[0087] The second bend 2022 is located in the second sub-duct 112. The second bend 2022 has an obstructive effect on the passing heat exchange air, which can change the flow direction of the heat exchange air. 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-duct 112 will flow toward the axial direction of the second sub-duct 112, that is, the heat exchange air will flow in the direction away from the outer surface of the air dividing rib 20, thereby avoiding condensation on the outer surface of the connecting section 203.

[0088] Alternatively, as Figure 4 and Figure 5 As shown, the first side wall surface 201 includes a first sub-side wall surface 2013 and a second sub-side wall surface 2014 arranged in sequence along the flow direction of the airflow (heat exchange air), the first sub-side wall surface 2013 and the second sub-side wall surface 2014 are connected and a first bend 2012 is formed at the connection, and the first bend 2012 protrudes from the second sub-side wall surface 2014 toward the axial direction of the first sub-duct 111; and / or the second side wall surface 202 includes a third sub-side wall surface 2023 and a fourth sub-side wall surface 2024 arranged in sequence along the flow direction of the airflow (heat exchange air), the third sub-side wall surface 2023 and the fourth sub-side wall surface 2024 are connected and a second bend 2022 is formed at the connection, and the second bend 2022 protrudes from the fourth sub-side wall surface 2024 toward the axial direction of the second sub-duct 112.

[0089] The first bend 2012 protrudes from the second sub-side wall 2014 toward the axis of the first sub-duct 111. Therefore, the first sub-side wall 2013 and the second sub-side wall 2014 are not in the same plane, that is, the first sub-side wall 2013 and the second sub-side wall 2014 are staggered. The distance between the first sub-side wall 2013 and the axis of the first sub-duct 111 is less than the distance between the second sub-side wall 2014 and the axis of the first sub-duct 111. Therefore, the heat exchange air flows out along the length of the first sub-side wall 2013, and the distance between the heat exchange air and the second sub-side wall 2014 is greater. This increases the distance between the heat exchange air and the connecting section 203, and prevents condensation from forming on the outer surface of the connecting section 203. The first bend 2012 may protrude from the first sub-side wall 2013 toward the axis of the first sub-duct 111, or may not protrude from the first sub-side wall 2013.

[0090] The second bend 2022 protrudes from the fourth sub-side wall 2024 toward the axis of the second sub-duct 112. Therefore, the third sub-side wall 2023 and the fourth sub-side wall 2024 are not in the same plane, that is, the third sub-side wall 2023 and the fourth sub-side wall 2024 are staggered. The distance between the third sub-side wall 2023 and the axis of the second sub-duct 112 is less than the distance between the fourth sub-side wall 2024 and the axis of the second sub-duct 112. Therefore, the hot exchange air flows out along the length of the third sub-side wall 2023, and the distance between the hot exchange air and the fourth sub-side wall 2024 is greater. This increases the distance between the hot exchange air and the connecting section 203, and prevents condensation from forming on the outer surface of the connecting section 203. The second bend 2022 may protrude from the third sub-side wall 2023 toward the axis of the second sub-duct 112, or may not protrude from the third sub-side wall 2023.

[0091] Moreover, at a lower air conditioner speed, condensation generated at the intersection of the heat exchange air and the indoor air can be eliminated.

[0092] Alternatively, as Figure 4 As shown, the first side wall 201 also includes a first transition wall 2015, which is arranged between the first sub-side wall 2013 and the second sub-side wall 2014, and a first corner 2016 is formed at the connection between the first transition wall 2015 and the first sub-side wall 2013. The first corner 2016 protrudes from the first transition wall 2015 toward the axial direction of the first sub-duct 111, and a second corner 2017 is formed at the connection between the first transition wall 2015 and the second sub-side wall 2014. The first bend 2012 includes the first corner 2016.

[0093] The first corner 2016 protrudes from the first transition wall 2015 in the direction of the axis of the first sub-duct 111. Specifically, the distance between the first corner 2016 and the first sub-duct 111 in the direction of the axis is less than the distance between the first transition wall 2015 and the first sub-duct 111 in the direction of the axis. This allows the first corner 2016 to redirect the flow of the heat exchange air and 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, respectively. The provision of the first transition wall 2015 makes the first side wall 201 smoother overall, reducing airflow loss and avoiding potential noise issues.

[0094] The second side wall surface 202 also includes a second transition wall surface, which is arranged between the third sub-side wall surface 2023 and the fourth sub-side wall surface 2024, and the connection between the second transition wall surface and the third sub-side wall surface 2023 forms a third corner, the third corner protrudes from the second transition wall surface toward the axial direction of the third sub-air duct 113, the connection between the second transition wall surface and the fourth sub-side wall surface 2024 forms a fourth corner, and the second bend 2022 includes the third corner.

[0095] 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 second sub-duct 112 in the direction of the axis is less than the distance between the second transition wall and the second sub-duct 112 in the direction of the axis. This allows the third corner to change the flow direction of the heat exchange air and creates a gap between the heat exchange air and the fourth sub-side wall 2024. The third and fourth corners are located at opposite ends of the second transition wall, respectively. The provision of the second transition wall makes the second side wall 202 smoother overall, reducing airflow loss and avoiding potential noise issues.

[0096] Optionally, a first protrusion is provided at the first bend 2012, and the first air guide portion 2011 further includes a first protrusion; and / or, as Figure 5 As shown, a second protrusion 2025 is provided at the second bend 2022 , and the second air guide portion 2021 further includes a second protrusion 2025 .

[0097] When the heat exchange air flows through the first protrusion, the first protrusion will change the flow direction of the heat exchange air and flow out along the length direction of the first sub-side wall 2013. The first protrusion increases the height of the first bend 2012 protruding toward the axial direction of the first sub-air duct 111, and also enhances the effect of redirecting the heat exchange air.

[0098] When the heat exchange air flows through the second protrusion 2025, the second protrusion 2025 will change the flow direction of the heat exchange air and flow out along the length direction of the third sub-side wall 2023. The second protrusion 2025 increases the height of the second bend 2022 protruding toward the axial direction of the second sub-air duct 112, and also enhances the effect of redirecting the heat exchange air.

[0099] Alternatively, as Figure 9 and Figure 10 As shown, the first side wall surface 201 is provided with a third protrusion 303, and the first air guide portion 2011 includes the third protrusion 303; and / or the second side wall surface 202 is provided with a fourth protrusion 304, and the second air guide portion 2021 includes the fourth protrusion 304.

[0100] The third protrusion 303 changes the flow direction of the heat exchange air in the first sub-air duct 111, so that the airflow of the heat exchange air changes direction when it flows to the third protrusion 303, and flows out along the outer surface of the third protrusion 303, thereby increasing the distance between the heat exchange air and the second sub-side wall 2014, thereby increasing the distance between the heat exchange air and the connecting section 203, so as to achieve the effect of avoiding condensation at the connecting section 203.

[0101] 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 it flows to 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 2024, thereby increasing the distance between the heat exchange air and the connecting section 203, so as to achieve the effect of avoiding condensation at the connecting section 203.

[0102] The third protrusion 303 and the fourth protrusion 304 can be designed to have a simple structure to reduce the difficulty of demolding and ensure the molding quality. For example, they can be designed to have a long strip shape.

[0103] Alternatively, as Figure 9 As shown, the first side wall surface 201 includes a first end 309 and a second end 310, and the first end 309 and the second end 310 are arranged in sequence along the flow direction of the airflow, and the distance A between the third protrusion 303 and the first end 309 is less than or equal to half of the length B of the first side wall surface 201, that is, A≤1 / 2B, wherein the length direction of the first side wall surface 201 is the distance from the first end 309 to the second end 310; the second side wall surface 202 includes a third end 311 and a fourth end 312, and the third end 311 and the fourth end 312 are arranged in sequence along the flow direction of the airflow, and the distance C between the fourth protrusion 304 and the third end 311 is less than or equal to half of the length D of the second side wall surface 202, C≤1 / 2D, wherein the length direction of the second side wall surface 202 is the distance from the third end 311 to the fourth end 312.

[0104] The third protrusion 303 is arranged between the first end 309 and the second end 310, and the distance between the third protrusion 303 and the first end 309 is less than or equal to half the length of the first side wall surface 201, so that the heat exchange air can be affected by the third protrusion 303 as soon as possible when flowing along the first side wall surface 201, so that the flow direction is changed. In this way, when the heat exchange air continues to flow over the third protrusion 303, 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 condensation at the connecting section 203.

[0105] 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 the length of the second side wall surface 202, so that the heat exchange air can be affected by the fourth protrusion 304 as soon as possible when flowing along the second side wall surface 202, so that the flow direction is changed. In this way, 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 condensation at the connecting section 203.

[0106] Alternatively, as Figure 10 As shown, the first side wall surface 201 includes a first section 305 and a second section 306 arranged in sequence along the flow direction of the airflow, and the third protrusion 303 is arranged between the first section 305 and the second section 306, wherein the third protrusion 303 forms an obtuse angle with the first section 305 and an acute angle with the second section 306.

[0107] The third protrusion 303 divides the first side wall surface 201 into a first section 305 and a second section 306. The third protrusion 303 forms an obtuse angle with the first section 305, which can reduce the resistance to the heat exchange air, so that the third protrusion 303 has a flow rate reduction effect on the heat exchange air. According to the wall attachment effect, the third protrusion 303 forms an acute angle with the second section 306, which can prevent the heat exchange air from flowing along the second section 306 and increase the distance between the heat exchange air and the second section 306.

[0108] The second side wall surface 202 includes a third section 307 and a fourth section 308 arranged in sequence along the flow direction of the airflow, and the fourth protrusion 304 is arranged between the third section 307 and the fourth section 308, wherein the fourth protrusion 304 forms an obtuse angle with the third section 307 and an acute angle with the fourth section 308.

[0109] The fourth protrusion 304 divides the second side wall surface 202 into a third section 307 and a fourth section 308. The fourth protrusion 304 forms an obtuse angle with the third section 307, which can reduce the resistance to the heat exchange air, so that the fourth protrusion 304 has a reducing effect on the flow rate of the heat exchange air. According to the wall attachment effect, the fourth protrusion 304 forms an acute angle with the fourth section 308, which can prevent the heat exchange air from flowing along the fourth section 308 and increase the distance between the heat exchange air and the fourth section 308.

[0110] Alternatively, as Figure 12As shown, the connecting section 203 includes a fifth end 2031 and a sixth end 3032, the fifth end 2031 is located in the first sub-duct 111, and the sixth end 3032 is located in the second sub-duct 112, the height F of the third protrusion 303 is less than or equal to the distance E between the fifth end 2031 and the first side wall surface 201 and is greater than or equal to half of the distance E between the fifth end 2031 and the first side wall surface 201, and the height of the fourth protrusion 304 is less than or equal to the distance between the sixth end 3032 and the second side wall surface 202 and is greater than or equal to half of the distance between the sixth end 3032 and the second side wall surface 202.

[0111] The height F of the third protrusion 303 is less than or equal to the distance E between the fifth end 2031 and the first side wall surface 201 and greater than or equal to half of the distance between the fifth end 2031 and the first side wall surface 201, that is, 1 / 2E≤F≤E, so that the third protrusion 303 can change the direction of the heat exchange air without having a significant impact on the air volume of the heat exchange air.

[0112] The height G of the fourth protrusion 304 is less than or equal to the distance H between the sixth end 3032 and the second side wall surface 202 and greater than or equal to half of the distance between the sixth end 3032 and the second side wall surface 202, that is, 1 / 2H≤G≤H, so that the fourth protrusion 304 can change the direction of the heat exchange air without having a significant impact on the air volume of the heat exchange air.

[0113] Alternatively, as Figure 1 As shown, the indoor unit further includes an air distribution grille 40.

[0114] The air duct includes an upstream air duct and a downstream air duct that are connected and arranged in sequence along the direction of air flow, and the air outlet is connected to the downstream air duct; the air dividing ribs 20 are arranged in the downstream air duct and divide the downstream air duct into a first sub-air duct 111 and a second sub-air duct 112; the air dividing grille 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.

[0115] The air volume flowing into the first sub-duct 111 and the second sub-duct 112 is adjusted through the air distribution grille 40, thereby adjusting the air volume outgoing through the first sub-duct 111 and the second sub-duct 112 to further improve the air supply comfort.

[0116] The air outlet volume of the first sub-duct 111 and the second sub-duct 112 is adjusted by using the air distribution grille 40, so that there is no need to adjust the setting of the duct profile, or the change to the duct profile is relatively small. In other words, the air volume of the first sub-duct 111 and the second sub-duct 112 can be adjusted without changing the duct profile or making relatively small changes to the duct profile. This adjustment method is simple and low-cost.

[0117] Alternatively, as Figure 1As shown, the air distribution grille 40 includes a first grille 401. The first grille is arranged corresponding to the air distribution rib 20 and extends along the direction of air flow, dividing the upstream air duct into a third sub-duct 113 and a fourth sub-duct 114. The third sub-duct 113 is connected to the first sub-duct 111, and the fourth sub-duct 114 is connected to the second sub-duct 112.

[0118] A first grille 401 is set in the upstream air duct, and the first grille 401 divides the upstream air duct into a third sub-duct 113 and a fourth sub-duct 114. The third sub-duct 113 corresponds to the first sub-duct 111, and the fourth sub-duct 114 corresponds to the second sub-duct 112. When the heat exchange air flows out of the air duct and encounters the first grille 401, it is divided into two parts by the first grille 401. One part flows through the third sub-duct 113 and enters the first sub-duct 111, and the other part flows through the fourth sub-duct 114 and enters the second sub-duct 112. Therefore, the amount of air flowing into the first sub-duct 111 and the second sub-duct 112 can be adjusted by parameters such as the length of the first grille 401 and whether it is tilted, thereby improving the air supply comfort of the air conditioner.

[0119] Optionally, the air distribution grille 40 further includes a second grille 402 and / or a third grille 403. The second grille 402 is provided in the third sub-air duct 113 and extends along the airflow direction; the third grille 403 is provided in the fourth sub-air duct 114 and extends along the airflow direction.

[0120] The second grille 402 is arranged in the third sub-duct 113, and the second grille 402 extends along the direction of air flow, dividing the third sub-duct 113 into two spaces. When the air flow passes through the third sub-duct 113, it can be divided into two air flows through the second grille 402. Therefore, the purpose of adjusting the air output of the first sub-duct 111 can be achieved by adjusting the length of the second grille 402, whether it is tilted, and other parameters, thereby adjusting the amount of air flowing out of the first sub-duct 111; the third grille 403 is arranged in the fourth sub-duct 114, and the third grille 403 extends along the direction of air flow, dividing the fourth sub-duct 114 into two spaces. When the air flow passes through the fourth sub-duct 114, it can be divided into two air flows through the third grille 403. The purpose of adjusting the air output of the second sub-duct 112 can be achieved by adjusting the length of the third grille 403, whether it is tilted, and other parameters, thereby adjusting the amount of air flowing out of the second sub-duct 112, thereby improving user comfort and satisfaction.

[0121] Alternatively, as Figure 1 As shown, the length of the first grid 401 is greater than the length of the second grid 402 ; and / or the length of the first grid 401 is greater than the length of the third grid 403 .

[0122] The first grille 401 is disposed between the second grille 402 and the third grille 403. The configuration of the first grille 401 divides the upstream air duct into the third sub-duct 113 and the fourth sub-duct 114. The second grille 402 and the third grille 403 are located within the third sub-duct 113 and the fourth sub-duct 114, respectively. When the first grille 401, the second grille 402, and the third grille 403 are the same length, the wind resistance to the airflow in the upstream air duct increases, and the air volume decreases. The first grille 401 is used to roughly divide the airflow into two parts and roughly adjust the air volume of the first sub-duct 111 and the second sub-duct 112. The second grille 402 and the third grille 403 are used to fine-tune the air volume in the first sub-duct 111 and the second sub-duct 112, respectively. Therefore, the length of the first grille 401 is set to be greater than the length of the second grille 402, and the length of the first grille 401 is set to be greater than the length of the third grille 403.

[0123] Alternatively, as Figure 1 As shown, the side walls of the air duct include a first air duct wall 115 and a second air duct wall 116, the first air duct wall 115 constituting at least a portion of the air duct wall of the third sub-air duct 113; the second air duct wall 116 is arranged opposite to the first air duct wall 115, constituting at least a portion of the air duct wall of the fourth sub-air duct 114; wherein, the first air duct wall 115 protrudes in a direction away from the air duct axis, and the second air duct wall 116 protrudes in a direction close to the air duct axis.

[0124] The first duct wall 115 and the first side wall 201 define a first sub-duct 111 , the first duct wall 115 and the first grille 401 define a third sub-duct 113 , the second duct wall 116 and the second side wall 202 define a second sub-duct 112 , and the second duct wall 116 and the first grille 401 define a fourth sub-duct 114 .

[0125] The first duct wall 115 protrudes in a direction away from the duct axis to increase the width of the first sub-duct 111 and the third sub-duct 113, and increase the air outlet of the first sub-duct 111 and the second sub-duct 112; the second duct wall 116 protrudes in a direction close to the duct axis to reduce the width of the second sub-duct 112 and the fourth sub-duct 114, and increase the air outlet of the second sub-duct 112 and the fourth sub-duct 114.

[0126] Optionally, the second grille 402 is linear; there are multiple second grilles 402, and the multiple second grilles 402 are arranged in sequence along the width direction of the third sub-air duct 113. In the direction close to the first air duct wall 115, the inclination angle of the second grille 402 becomes larger and / or the length of the second grille 402 becomes larger.

[0127] The second grille 402 is arranged in a straight line and is inclined toward the first air duct wall 115 along the direction of air flow to direct the air flow toward the first air duct wall 115. The straight line arrangement of the second grille 402 can improve the smoothness and uniformity of air flow, facilitate uniform air flow from the first sub-air outlet 123, and meet the user's usage requirements.

[0128] Multiple second grilles 402 are arranged in sequence along the width direction of the third sub-air duct 113, and the inclination angle of the second grilles 402 becomes larger in the direction close to the first air duct wall 115, that is, the multiple second grilles 402 are not parallel, the inclination angle of the second grilles 402 close to the first air duct wall 115 is large, and the inclination angle of the second grilles 402 away from the first air duct wall 115 is small, so as to guide the airflow toward the first air duct wall 115 and increase the air outlet range of the first sub-air outlet 123.

[0129] Alternatively, as Figure 6 As shown, the third grille 403 includes a first grille segment 4031 and a second grille segment 4032 arranged in sequence along the air flow direction. The first grille segment 4031 is connected to the second grille segment 4032 and the second grille segment 4032 is located on the side of the first grille segment 4031 facing the second air duct wall 116.

[0130] The third grille 403 is not linear, but includes a first section 4031 and a second section 4032 arranged sequentially along the airflow direction. The distance between the first section 4031 and the second duct wall 116 is greater than the distance between the second section 4032 and the second duct wall 116, thereby directing the airflow toward the second duct wall 116 and increasing the airflow range of the second sub-air outlet 124. The arrangement of the first section 4031 and the second section 4032 adjusts the airflow direction, allowing the airflow to flow more smoothly through the fourth sub-duct 114, reducing obstructions to airflow, improving airflow performance and reducing energy consumption. It also prevents airflow from directly hitting the user, reducing discomfort and improving comfort.

[0131] Optionally, there are multiple third grilles 403, and the multiple third grilles 403 are sequentially arranged along the width direction of the fourth sub-duct 114, and the length of the third grilles 403 decreases as they approach the second duct wall 116. In other words, among the multiple third grilles 403, the third grilles 403 farther away from the second duct wall 116 are longer, and the third grilles 403 closer to the second duct wall 116 are shorter.

[0132] The length of the third grille 403 will affect the air volume. When other parameters of the third grille 403 are the same, the longer the third grille 403 is, the greater the wind resistance is, and the shorter the length is, the smaller the wind resistance is. Therefore, as the length of the third grille 403 decreases in the direction close to the second air duct wall 116, the end of the second sub-air outlet 124 away from the first sub-air outlet 123 (i.e. Figure 1 The air outlet of the second sub-air outlet 124 is increased (at the right end of the second sub-air outlet 124), so that the air outlet at each part of the second sub-air outlet 124 is more uniform.

[0133] Optionally, the indoor unit further includes a driving device, which is drivingly connected to the air distribution grille 40 and is used to drive the air distribution grille 40 to move relative to the air duct.

[0134] The movement of the air distribution grille 40 is driven by a driving device to adjust at least one of the spacing between two adjacent second grilles 402, the spacing between the second grille 402 and the first grille 401, the spacing between the first grille 401 and the third grille 403, the spacing between two adjacent third grilles 403, the inclination angle of the second grille 402, the inclination angle of the first grille, and the inclination angle of the third grille 403, so as to further adjust the air outlet parameters of the first sub-air outlet 123 and the second sub-air outlet 124.

[0135] The driving device can adjust the parameters of each air distribution grille 40 (including the tilt angle and the distance from the adjacent air distribution grille 40 ) respectively, and can also adjust the parameters of at least two air distribution grilles 40 synchronously.

[0136] When the driving device needs to synchronously adjust the parameters of at least two air distribution grilles 40, a connecting rod can be set between the air distribution grilles 40, and the driving device is connected to the connecting rod. The driving device drives the connecting rod to move and adjusts the parameters of multiple air distribution grilles 40 through the connecting rod.

[0137] According to a second aspect of an embodiment of the present invention, an air conditioner is provided, comprising an indoor unit, the indoor unit comprising a housing assembly for an air conditioner indoor unit as described in any one of the above embodiments and a fan 60; the fan 60 is arranged in an air duct.

[0138] The air conditioner provided in the embodiment of the second aspect of the present invention includes the shell assembly as described in any one of the above embodiments, and thus has all the beneficial effects of the shell assembly as described in any one of the above embodiments, which will not be repeated here.

[0139] Optionally, the indoor unit further includes an air deflector 50. The air deflector 50 is disposed at the air outlet and is movably connected to the housing 100. The air deflector 50 is movable relative to the housing 100 between a closed position for closing the air outlet and an open position for opening the air outlet. In the closed position, the air deflector 50 is located outside the groove 15.

[0140] When the air conditioner is turned on, the air guide plate 50 is opened to the open position, and the air is blown out from the air outlet. The air guide plate 50 has the function of adjusting the wind direction. By adjusting the position of the air guide plate 50, the direction of the air outlet is changed, so that the air outlet direction of the indoor unit is diversified, which can meet the different usage requirements of users and improve the user experience. When the air conditioner is turned off, the air guide plate 50 closes the air outlet, which can prevent dust from entering the air outlet and play a certain protective and dust-proof role.

[0141] In the closed position, the air guide plate 50 is located outside the groove 15 , so that the air guide plate 50 blocks the groove 15 , preventing the groove 15 from affecting the appearance of the housing 100 .

[0142] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless expressly required, individual components and functions are optional, and the order of operations may vary. Portions and features of some embodiments may be included in or replace portions and features of other embodiments. The embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
