[0060] Embodiments of the present application are described in detail below with reference to examples illustrated in the accompanying drawings, in which the same or similar components or components having the same or similar functions are denoted by the same or similar reference numerals throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are intended only to explain the present application, and should not be construed as limiting the present application.

[0061] In the description of the present application, it should be understood that the terms "longitudinal", "transverse", "length", "thickness", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0062] The air conditioner indoor unit 1000 according to an embodiment of the present application will be described below with reference to the accompanying drawings. The air conditioner indoor unit 1000 can adjust the temperature of indoor airflow and is suitable for various indoor occasions such as living rooms, offices, and laboratories.

[0063] The air conditioner indoor unit 1000 according to an embodiment of the present application, as shown in Figure 1 , comprises an air conditioner housing 100.

[0064] As shown in Figure 2 , the air conditioner housing 100 comprises a back plate 110, two side plates 120, and fasteners. As shown in Figure 3 and Figure 4 , the edge of the back plate 110 is provided with a mounting portion 111, where the edge mainly refers to the end side of the plate rather than the plate surface.

[0065] As shown in Figure 3 , the two side plates 120 are connected to opposite sides of the back plate 110, for example, the left side and the right side as shown in the drawings. The space between the two side plates 120 and the back plate 110 is enclosed to form an assembly space 101, which can be used to mount other internal components.

[0066] As shown in Figure 4 , the edge of the side plate 120 is provided with a first mounting edge 121 and a second mounting edge 122 extending in different directions, and a positioning groove 123 is formed between the first mounting edge 121 and the second mounting edge 122, which positions the mounting portion 111. That is, the edge of the side plate 120 facing the back plate 110 forms two diverging first mounting edges 121 and second mounting edges 122, and the two mounting edges can be fitted on different sides of the mounting portion 111, respectively.

[0067] As shown in Figure 4 , the fasteners are connected to the second mounting edge 122 and the mounting portion 111 in the assembly space 101, respectively, so that the fasteners do not need to be assembled from the back side of the back plate 110 to the inside of the assembly space 101, but are fastened from the inside of the assembly space 101 to the side plate 120 and the back plate 110.

[0068] From the above structure, the indoor unit 1000 of the air conditioner of the embodiment of the present application can form a certain predetermined assembly relationship between the back plate 110 and the side plate 120 through the positioning and cooperation of the mounting portion 111 and the positioning groove 123; when the first mounting edge 121 and the second mounting edge 122 simultaneously abut against the two surfaces of the mounting portion 111, the outer surface of the mounting portion 111 and the inner surface of the positioning groove 123 form a close assembly, at this time, the fastener fastens the second mounting edge 122 and the mounting portion 111 from the assembly space 101, so that the back plate 110 forms a stable connection relative to the side plate 120.

[0069] In the above assembly process, the back plate 110 can be placed on the assembly line, the inner side of the back plate 110 faces upward, and the two side plates 120 are positioned by hand or clamps respectively, so that the two side plates 120 form a pre-assembly position relative to the back plate 110 respectively; then the fastener is used to tighten the side plate 120 and the back plate 110 in turn, thereby forming a preliminary mounting frame. In this process, the back plate 110 does not need to be turned over, which saves the assembly time required for turning over, and avoids the problem of damage caused by the side plate 120 falling off the back plate 110 during the installation process after turning over. Thus, the air conditioner shell 100 of the present application is assembled quickly, and the assembly efficiency of the back plate 110 and the side plate 120 is high.

[0070] It can be understood that, compared with the prior art scheme of turning over the back plate when fixing the side plate and the back plate, the air conditioner shell 100 of the indoor unit 1000 of the present application has high assembly efficiency, high assembly qualification rate, convenient operation for workers, stable mounting frame, and is convenient for assembling other internal components. Compared with the prior art scheme of relying on the chassis positioning when fixing the side plate and the back plate, the assembly of the air conditioner shell 100 of the present application is more flexible and efficient, and is convenient for cooperation with other components.

[0071] Optionally, the fastener is a screw or a bolt, so that the back plate 110 and the side plate 120 can form a relatively stable connection.

[0072] Advantageously, the two side plates 120 are arranged opposite to each other, and the connection structures between each side plate 120 and the back plate 110 are substantially similar. For example, in a specific example, the first mounting edge 121 on the two side plates 120 is symmetrically arranged with the central axis of the back plate 110 as the symmetry axis, and the second mounting edge 122 on the two side plates 120 is also symmetrically arranged with the central axis of the back plate 110 as the symmetry axis, so that after the two side plates 120 are assembled on the back plate 110, the main bodies can be parallel, which is beneficial to controlling the space size of the assembly space 101 to be sufficient.

[0073] In some embodiments of the present application, as Figure 4As shown, the mounting portion 111 comprises a first mounting portion 1111 and a second mounting portion 1112 connected at an angle, that is, an intersection angle is formed between the first mounting portion 1111 and the second mounting portion 1112, and the intersection angle should be matched with the included angle between the first mounting edge 121 and the second mounting edge 122, so that the first mounting portion 1111 is matched with the inner surface of one side of the positioning groove 123, and the second mounting portion 1112 is also matched with the inner surface of the other side of the positioning groove 123.

[0074] Further, as shown, Figure 4 The first mounting portion 1111 is connected to the back plate 110, and the first mounting edge 121 covers the outside of the first mounting portion 1111, so that the first mounting portion 1111 is not coplanar with the back plate 110, and the first mounting edge 121 can cover the first mounting portion 1111, so that the first mounting portion 1111 is not exposed, and the appearance and integrity of the air conditioner shell 100 when viewed from the side are ensured. In a specific example, the first mounting portion 1111 preferably extends outward from the plane of the back plate 110, so that the first mounting portion 1111 can make the assembled space 101 formed by the connection of the side plate 120 and the back plate 110 larger.

[0075] Further, the second mounting portion 1112 extends inward into the assembled space 101, so that the second mounting portion 1112 can return to the assembled space 101, and the second mounting edge 122 is connected to the second mounting portion 1112, facilitating the sequential passing of the fastener from the assembled space 101 through the second mounting edge 122 and the second mounting portion 1112. The second mounting portion 1112 provides sufficient support surface and connection surface for the second mounting edge 122.

[0076] Alternatively, the intersection angle between the first mounting portion 1111 and the back plate 110 is obtuse, so that the first mounting portion 1111 extends outward along the edge of the back plate 110. Compared with the case where the intersection angle between the first mounting portion 1111 and the back plate 110 is a right angle, the outwardly inclined first mounting portion 1111 can provide a larger connection surface for the first mounting edge 121, and can make the edge space of the internal assembled space 101 larger, thereby facilitating the assembly of other cooperating parts on the side plate 120, such as the air inlet grille 210, the first filter 220, and the like.

[0077] Of course, in other examples, the included angle between the first mounting portion 1111 and the back plate 110 is not limited to an obtuse angle, for example, the included angle between the first mounting portion 1111 and the back plate 110 can also be a right angle, at this time, the first mounting portion 1111 extends perpendicular to the surface on which the back plate 110 is located, so that the second mounting portion 1112 connected to the first mounting portion 1111 can be spaced apart from the back plate 110, and a certain space is formed between the second mounting portion 1112, the first mounting portion 1111 and the back plate 110 for avoiding the fastener, thereby preventing the end of the fastener from piercing the back plate 110, ensuring the integrity of the back plate 110 and improving the aesthetic appearance of the external appearance of the back plate 110.

[0078] Optionally, the included angle between the first mounting portion 1111 and the second mounting portion 1112 is an acute angle, these examples are mainly suitable for the case where the first mounting portion 1111 extends obliquely outward along the edge of the back plate 110, so that the second mounting portion 1112 can correct the case where the back plate 110 is exposed in the assembly space 101 due to the oblique extension of the first mounting portion 1111, and the second mounting portion 1112 can shield part of the back plate 110 and avoid the back plate 110 being fastened by the fastener, so that the second mounting portion 1112 can form a positioning cooperation with the second mounting edge 122 instead of the back plate 110, and further fasten the connection.

[0079] In other examples, the included angle between the first mounting portion 1111 and the second mounting portion 1112 is not limited to the aforementioned acute angle, for example, it can be a right angle, these examples are mainly suitable for the case where the first mounting portion 1111 extends perpendicular to the surface on which the back plate 110 is located, so that the second mounting portion 1112 can be spaced apart from the back plate 110, and the second mounting portion 1112 can be substantially parallel to the surface on which the back plate 110 is located, thereby providing sufficient mounting surface for the second mounting edge 122, and the mounting surface is visible.

[0080] Advantageously, as shown in the drawings, Figure 5 The mounting portion 111 further includes a third mounting portion 1113 connected to the second mounting portion 1112, and the third mounting portion 1113 extends towards the back plate 110, so that the third mounting portion 1113 can further shield the gap formed between the second mounting portion 1112 and the back plate 110, and the space enclosed by the first mounting portion 1111, the second mounting portion 1112, the third mounting portion 1113 and the back plate 110 is relatively closed, effectively preventing the edges of the second mounting portion 1112 from scratching other components to be installed in the assembly space 101, and also making the local strength of the entire mounting portion 111 higher, so that the mounting portion 111 is not easy to deform after the fastener is installed. In these examples, the mounting portion 111 forms three folds relative to the back plate 110, thereby forming a relatively stable edge covering assembly.

[0081] In the description of the present application, the features defined as "first", "second", "third" can explicitly or implicitly include one or more of the features, for distinguishing the description features, without order and without emphasis.

[0082] Advantageously, the second mounting portion 1112 is arranged in parallel with the back plate 110, so that the second mounting portion 1112 is spaced apart from the back plate 110 in the front-rear direction in the drawing, and the second mounting portion 1112 is located in the assembly space 101 and is fixed by the fastener after being close to the second mounting edge 122.

[0083] Optionally, the mounting portion 111 is arranged along the height direction of the back plate 110 as a whole, and the mounting portion 111 located at each side edge of the back plate 110 is formed with multiple bends towards the inside, so that the mounting portion 111 not only has a certain positioning angle, but also has a corresponding mounting surface, and also has sufficient strength.

[0084] Advantageously, the side plate 120 is an injection-molded integral part, and when the side plate 120 is accidentally dropped during installation, the side plate 120 can restore to its original state even if it is deformed to a certain extent, thereby reducing the probability of the side plate 120 being scrapped due to operation errors during installation.

[0085] Advantageously, as shown in Figure 6 , Figure 7 and Figure 1 , the side plate 120 is provided with a reinforcing rib 128 connected between the side plate 120 and the second mounting edge 122, so as to improve the stability of the second mounting edge 122 relative to the side plate 120 itself, avoid cracking of the second mounting edge 122 during fastening with the second mounting portion 1112, and improve the local strength of the side plate 120 and the stability after fastening of the fastener. In the description of the present application, "multiple" means two or more, unless otherwise specified.

[0086] Optionally, the multiple reinforcing ribs 128 are arranged at intervals along the height direction of the side plate 120, so as to ensure the structural strength of the side plate 120 at each location, facilitate multiple fastenings of the side plate 120 and the back plate 110, and reduce the gap between the side plate 120 and the back plate 110 after installation, thereby reducing the abnormal sound.

[0087] Advantageously, the side plate 120 is bent and extended inwardly at the side portion close to the back plate 110, so that the first mounting edge 121 and the second mounting edge 122 provided at the end of the side plate 120 can better cooperate with the mounting portion 111 on the back plate 110.

[0088] In some embodiments of the present application, in combination with Figure 5 and Figure 5 , the air conditioner indoor unit 1000 further comprises an air inlet grille 210 and a first filter 220. As shown inFigure 6 As shown, the side plate 120 is provided with an air inlet 124, which can be used for air intake. An air inlet grille 210 is assembled at the air inlet 124, which can isolate the lint and other objects mixed in the air passing through, so as to block larger impurities from entering the air conditioner shell 100 during air intake; in addition, the air inlet grille 210 can also effectively prevent children from putting their hands into the air conditioner shell 100 and causing danger.

[0089] Further, as shown in Figure 7 and Figure 5 , the first filter 220 is pullably connected between the air inlet grille 210 and the air inlet 124, which can effectively purify the air passing through the air inlet 124 and trap smaller particulate matter, so that the air entering the air conditioner indoor unit 1000 is relatively clean, avoiding the blockage of the air duct or the pollution of the internal components by the small particulate matter. The pullable design of the first filter 220 allows the user to pull out the first filter 220 manually without removing the air inlet grille 210 when it needs to be replaced or cleaned, which is convenient for cleaning and maintenance and improves user satisfaction. As for the direction of pulling, it can be designed to pull from bottom to top, or from top to bottom, or from left to right, or from right to left, which is not specifically limited here, and the convenience of pulling and the aesthetics are taken into account.

[0090] Optionally, as shown in Figure 5 , the first filter 220 includes a pulling part 221 and a filtering part 222, wherein the pulling part 221 is provided with a hand holding position, and the filtering part 222 is provided with a filter screen, so as to facilitate the hand holding position to be held by the hand for operation.

[0091] Optionally, as shown in Figure 5 , the edge of the air inlet 124 is provided with a sink 1241, and the sink wall of the sink 1241 is provided with a boss 1242 protruding towards the side away from the assembly space 101, so that the surface of the boss 1242 and the surface of the sink 1241 form a height difference. The air inlet grille 210 is assembled on the boss 1242, and the boss 1242 with the height difference and the sink 1241 make the assembled air inlet grille 210 and the sink 1241 form a certain assembly gap, so that the filtering part 222 of the first filter 220 can be easily connected between the sink 1241 and the air inlet grille 210, and it is also convenient to pull through the pulling part 221.

[0092] Optionally, the boss 1242 is provided with a mounting groove, and the air inlet grille 210 is provided with a plurality of buckles or snap buckles on a side facing the boss 1242, the buckles or snap buckles being detachably connected in the mounting groove, so as to realize detachable connection of the air inlet grille 210 and the boss 1242. The buckling or snap design facilitates disassembly and assembly of the air inlet grille 210, thereby facilitating thorough cleaning of the air inlet grille 210 when the air inlet grille 210 is full of sundries or dust.

[0093] Optionally, the air inlet grille 210 is further provided with a lug, and the lug is bolted with the sink 1241, so as to further fix the air inlet grille 210 on the air inlet 124.

[0094] Optionally, at least one barrier strip 125 is arranged at the air inlet 124, the barrier strip 125 is arranged in a spaced manner with the air inlet grille 210, and the filtering part 222 of the first filter 220 is connected between the barrier strip 125 and the air inlet grille 210. Then, the barrier strip 125 can effectively prevent the first filter 220 from protruding into the assembly space 101, so that the first filter 220 can be reliably retained between the air inlet 124 and the air inlet grille 210 to play its filtering effect.

[0095] In some specific examples, as shown in Figure 6 and Figure 9 , a plurality of barrier strips 125 are arranged in parallel and in a spaced manner along the height direction of the air inlet 124, so that the air inlet 124 can support or block the first filter 220 at multiple positions, effectively preventing the first filter 220 from being blown into the air conditioner housing 100 to interfere with the normal work of other internal components during the process of air inlet into the air inlet 124.

[0096] Optionally, the filtering part 222 of the first filter 220 is a combination of a filter screen, a filter core or a filter membrane and a structural frame, which is not specifically limited here, as long as it can achieve the effect of filtering and purifying the airflow.

[0097] Optionally, the air inlet grille 210 can be integrally formed with the side plate 120, facilitating processing and manufacturing, without the need for later assembly, and the gap between the air inlet grille 210 and the side plate 120 is fixed, which is conducive to stable realization of the pulling action of the first filter 220.

[0098] In some embodiments of the present application, as shown in Figure 10 and Figure 6 , the air conditioner indoor unit 1000 further comprises a fresh air component 300, which can introduce external fresh air into the room, so that the air conditioner indoor unit 1000 has a fresh air function. As shown in Figure 10As shown, the side plate 120 is provided with a fresh air outlet 126, and the fresh air outlet 126 is connected with an air outlet part of the fresh air component 300. That is, the air outlet part of the fresh air component 300 is opposite to the fresh air outlet 126, so that the fresh air introduced from outside can be blown into the room through the fresh air outlet 126, improving the oxygen content of the indoor air, avoiding the problem of the increase of the concentration of carbon dioxide caused by the long-term closed heat exchange cycle of the air conditioner indoor unit 1000 and the indoor air, making the air in the room fresh, and further improving the use comfort of the indoor air.

[0099] Optionally, when the air outlet part is clamped at the fresh air outlet 126, the fresh air component 300 can be kept stable when blowing fresh air into the room, and the fresh air component 300 is also convenient to disassemble.

[0100] Optionally, as shown in Figure 11 and Figure 10 , the periphery of the fresh air outlet 126 is provided with a clamping piece 1261, and the clamping piece 1261 is clamped at the periphery of the air outlet part, so that the air outlet part is aligned with the fresh air outlet 126. Here, the air outlet part can specifically refer to the air outlet scroll of the fresh air shell 310.

[0101] Of course, in other examples, the foregoing clamping piece 1261 can be replaced by a bolted connection piece, which simultaneously connects the air outlet part and the side plate 120. Here, no specific limitation is made as long as the air outlet part and the side plate 120 can be conveniently disassembled.

[0102] Advantageously, in order to prevent children from putting their hands into the fresh air component 300 and prevent other sundries from entering the fresh air component 300, a fresh air grille 1262 is arranged at the fresh air outlet 126 to form a block and a certain filtering; at the same time, the fresh air grille 1262 can also guide and disperse the fresh air flowing into the room, so that the fresh air is blown into the room gently.

[0103] Optionally, as shown in Figure 11 and Figure 7 , the fresh air component 300 comprises a fresh air shell 310 and a second filter 320, and the second filter 320 is detachably arranged in the fresh air shell 310. The second filter 320 can filter the air flowing through the fresh air shell 310, so that the cleanliness of the fresh air introduced into the room through the fresh air shell 310 is guaranteed, preventing dust and bacteria from being brought into the room. Further, the fresh air component 300 further comprises a fresh air fan (not shown in the figure) arranged in the fresh air shell 310. The fresh air fan can provide the power of air introduction, and is used to introduce the outdoor air into the fresh air shell 310, and then discharge the air into the room through the fresh air outlet 126 after being filtered by the second filter 320.

[0104] Further, as shown in Figure 10 , Figure 11 andFigure 10 As shown, the side plate 120 is provided with an opening 127, and the second filter 320 can be detached from the opening 127. Therefore, when the second filter 320 needs to be replaced or cleaned, the air conditioner shell 100 does not need to be opened, and the second filter 320 can be manually pulled out through the opening 127, thereby improving the convenience of cleaning and replacing the second filter 320 and facilitating the user to detach and clean the second filter 320.

[0105] Advantageously, as Figure 5 As shown, the fresh air shell 310 is provided with an arc-shaped mounting channel (not shown in the figure), and the second filter 320 is pullably arranged in the mounting channel, and part of the second filter 320 extends from the opening 127. In these examples, the externally introduced fresh air needs to pass through the second filter 320 with a larger flow cross section before entering the air outlet. It can be understood that, compared with the second filter 320 with a planar surface and an overall plate shape, the second filter 320 with a curved shape greatly improves the filtering area of the second filter 320 when the fresh air passes through, so that the fresh air introduced into the fresh air shell 310 can be efficiently filtered and purified, thereby improving the effect of the fresh air outlet. In addition, since the second filter 320 of the present application matches the mounting channel, it is convenient to pull and detach the second filter 320. The second filter 320 can also be pulled out along an arc-shaped trajectory, and the second filter 320 can avoid obstacles such as walls during the pulling process. It can be understood that, compared with a straight pulling trajectory, the second filter 320 of the present application is more flexible during the pulling process, reduces the required space during pulling, and adapts to the situation where the air conditioner indoor unit 1000 is installed in a corner.

[0106] Optionally, the second filter 320 can be any one of a filter screen and a filter element, and the second filter 320 can also be a composite filter screen, thereby improving the purification performance of the second filter 320.

[0107] Optionally, as Figure 10 and Figure 11 As shown, the back plate 110 is outwardly protruded to form a relief portion 112, which further increases the assembly space 101 on the inner side of the back plate 110. The relief portion 112 is provided with a fresh air inlet 113, and the air inlet end of the fresh air component 300 communicates with the fresh air inlet 113, so that fresh air can be introduced into the fresh air component 300. The fresh air inlet 113 can be externally connected to a pipeline and communicated to the outdoor, so as to facilitate the introduction of fresh air from the outdoor into the fresh air component 300.

[0108] Optionally, as Figure 12 and Figure 1As shown, the fresh air component 300 further comprises a fixing plate 330 connected with the fresh air shell 310, and the two ends of the fixing plate 330 are respectively positioned and connected on the side plate 120, so that the fresh air component 300 of the present application can be fixed in position relative to the side plate 120 and the back plate 110, and the assembly is stable.

[0109] For example, in a specific example, the side plate 120 is provided with a positioning block matched with the fixing plate 330, and the positioning block enables the side plate 120 and the fixing plate 330 to be quickly positioned; the side plate 120 is further provided with a fixing hole, and the fixing plate 330 is provided with a matched hole, and a bolt passes through the matched hole and the fixing hole to enable the side plate 120 and the fixing plate 330 to be positioned and connected.

[0110] In some embodiments of the present application, as shown in Figure 9 and Figure 1 As shown, the air conditioner indoor unit 1000 further comprises an air guide assembly 400, and the air conditioner shell 100 further comprises a panel assembly 130 provided with at least one air outlet 131, which can blow out the air after heat exchange by the air conditioner indoor unit 1000.

[0111] Further, the panel assembly 130 is connected on the side plate 120, and the air guide assembly 400 is arranged at the air outlet 131, which can guide the air flowing through the air outlet 131, improve the air supply range of the air outlet 131, and increase the air supply mode of the air conditioner indoor unit 1000. When there are multiple air outlets 131, the air guide assembly 400 is arranged at each air outlet 131 to ensure that the air flowing through the air outlet 131 can be effectively guided.

[0112] For example, in a specific example, when it is necessary to guide the hot air, the air guide assembly 400 guides the air downward, so that the hot air blows downward, which is beneficial to improve the heating performance of the whole house. When it is necessary to guide the cold air, the air guide assembly 400 guides the air upward, so that the cold air blows upward, which is beneficial to improve the cooling performance of the whole house. When multiple air outlets 131 are arranged, and multiple air guide assemblies 400 form an air guide combination, the air outlet of the air conditioner indoor unit 1000 at different height ranges can be realized, and the sinking air outlet and the windless air outlet can also be realized.

[0113] Optionally, the air guide assembly 400 comprises an air guide plate, a rotating support, and a driving mechanism for driving the rotation of the rotating support, the output end of the driving mechanism is connected with the rotating support, and the air guide plate is arranged on the rotating support. When the driving mechanism moves, the rotating support drives the air guide plate to rotate, so as to change the position of the air guide plate at the air outlet 131, and further change the opening degree and the air outlet direction of the air outlet 131. The air guide plate in these examples can also have the function of opening and closing the door, so as to close or open the air outlet 131, or adjust the opening angle of the air outlet 131.

[0114] Optionally, each rotating support is arranged at the air outlet 131 through a rotating shaft, both ends of the rotating shaft being rotatably connected to the panel assembly 130, so that the rotating support can rotate along the rotating shaft. For example, in a specific example, the axial direction of the rotating shaft is the left-right direction of the air conditioner shell 100, so that when the rotating support rotates, the air deflector can deflect air along the up-down direction of the air conditioner shell 100.

[0115] Optionally, the air deflector is an outwardly convex arc-shaped plate, when the air deflector completely covers the air outlet 131, the arc-shaped air deflector is partially exposed at the air outlet 131, and the air blown from the air outlet 131 is guided outward along the extension surface of the air deflector by utilizing the Coanda effect. In the state that the air deflector blocks the air outlet 131, the arc-shaped plate protrudes from the plane where the air outlet 131 is located, the arc-shaped plate can completely close the air outlet 131, and the arc-shaped plate is convenient to rotate with the rotating support, so that the rotating support does not jam during rotation.

[0116] Advantageously, a plurality of air holes can be further arranged on the air deflector, so that when the air deflector covers the air outlet 131, the air holes can still form a windless air outlet. The air deflector with the air holes does not completely block the air flow of the air outlet 131, but blows air to the indoor when the fan 500 continues to work. After the air holes are arranged on the air deflector, the design of the arc-shaped air deflector can make the air blown from the air conditioner shell 100 to the air outlet 131 more concentrated, and the concentrated air is blown outward from the air holes, thereby improving the air outlet intensity and efficiency of each air outlet 131.

[0117] Optionally, the air deflector assembly further comprises an air deflector louver, the air deflector louver being swingably arranged on the rotating support along the left-right direction, so as to left-right guide and adjust the air flowing through the air outlet 131. The left or right air deflector louver can respectively guide air to the left or right area of the air conditioner indoor unit 1000, so as to realize large-area air supply in the entire indoor. In the state that the air deflector avoids the air outlet 131, the air deflector louver is exposed to guide air, and in the state that the air deflector blocks the air outlet 131, the air deflector louver is invisible. In the state that the air deflector partially blocks the air outlet 131, the air deflector louver is partially invisible and partially visible, and at this time, the air deflector and the air deflector louver can jointly guide the air at the air outlet 131.

[0118] Optionally, the air deflector louver is arranged on the rotating support opposite to the air deflector louver, so that when the air deflector louver is exposed when the air deflector louver abuts against the air outlet 131, the air deflector louver can swing along the left-right direction and guide air, so that the air conditioner can form various air outlets.

[0119] Optionally, the air guide louver is a flexible louver. When the flexible louver is used, a smooth curved surface can be formed when the air guide louver swings to a certain angle, so that the airflow passing through is more smooth, and the airflow after heat exchange can be quickly guided to the indoor through the air guide louver. In addition, the flexible louver can also increase the toughness and deformation recovery performance of itself, so that the air guide louver is not easy to be damaged in the process of swinging.

[0120] Optionally, a plurality of air outlets 131 are arranged at intervals along the height direction of the panel assembly 130, and a plurality of air guide assemblies 400 are respectively arranged at the respective air outlets 131 for guiding, so as to realize air guiding of the air conditioner indoor unit 1000 in multiple areas in the height direction. When only the air outlet 131 with the highest position is completely opened, long-distance air supply can be formed. When the plurality of air outlets 131 are simultaneously opened, the air guide plate and / or the air guide louver of each air outlet 131 can be adjusted to form different air guiding forms, so that the final air outlet forms of the plurality of air outlets 131 are rich, which is beneficial to form large-range air supply; by adjusting the air guide plate or the air guide louver, the wind can also be dispersed, so that the wind blown out of the air outlet 131 is more soft, avoiding strong wind directly blowing on people, especially avoiding cold wind directly blowing on people. When all the air outlets 131 are completely blocked, the air guide plate and the air guide louver are no longer in work, so that the air outlet 131 can be closed, and the appearance of the whole machine is beautiful. At this time, the hand is not easy to stretch into the air conditioner shell 100, effectively protecting the safety of family members, especially children; insects, dander, etc. are also not easy to enter the air conditioner shell 100 from the air outlet 131, so that the inside of the air conditioner shell 100 is relatively clean, which is beneficial to prolong the service life of each part.
