[0046] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0047] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0048] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "front", "rear", "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0049] In the description of the present invention, if described as "first", "second", etc., it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0050] In the description of the present invention, it should be noted that the terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0051] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0052] During long-term use of the indoor unit of the air conditioner, dust and other dirt will accumulate on the inner wall of the air duct, the wind wheel and other parts, which is easy to breed bacteria and affect the air quality, so it needs to be cleaned regularly. In the related art, a driving mechanism is used to drive a dust removal tool to clean the wind wheel, without disassembling the wind wheel for cleaning. However, it can only clean the dust accumulated on the surface of the wind wheel, and the dirt dropped after cleaning needs to be handled manually in time. The operation is cumbersome, time-consuming and labor-intensive, and the scattered dust is easy to cause secondary pollution, and the cleaning effect is not ideal.

[0053] In the related art, some air-conditioning indoor units use structures such as brushes to scrub the wind wheel, but they do not have the function of sliding to sweep the wind wheel, resulting in the brush being unable to clean the entire wind wheel and the cleanliness level failing to meet the requirements; other air-conditioning indoor units use vacuuming to remove dust, but this type of structure has the problem of occupying a large space and having a high technical cost, which is not conducive to promotion.

[0054] In order to solve the above problems, an embodiment of the present invention provides an air conditioner indoor unit 1000, which is specifically a wall-mounted indoor unit. Figures 1 to 12 The air conditioner indoor unit 1000 according to an embodiment of the present invention is introduced.

[0055] Reference Figure 1 and Figure 2 As shown, the indoor unit 1000 of the air conditioner provided in the embodiment of the present invention comprises a housing, a duct structure 200, a heat exchanger 300 and a wind wheel 400. The duct structure 200, the heat exchanger 300 and the wind wheel 400 are all arranged in the housing. The duct structure 200 is provided with an air inlet 212 and an air outlet 211. The duct structure 200 is formed with a duct 201 connecting the air inlet 212 and the air outlet 211. The wind wheel 400 of the embodiment is a cross-flow wind wheel, which is installed in the duct structure 200. The heat exchanger 300 is arranged on one side of the air inlet 212 of the duct structure 200. The wind wheel 400 can drive air to enter the duct 201 after passing through the heat exchanger 300. The airflow passes through the heat exchanger 300 for heat exchange, forming cold air or hot air and blowing it into the room, thereby realizing the air conditioning function.

[0056] It can be understood that the housing includes a face frame and a base 100, the air duct structure 200 is disposed on the base 100, and the face frame is connected to the base 100. Figure 1 2 shows a front structural diagram of the air-conditioning indoor unit 1000 when the face frame is not installed.

[0057] Reference Figure 2 and Figure 3As shown, the air conditioner indoor unit 1000 of the embodiment of the present invention further includes a cleaning mechanism 500, the cleaning mechanism 500 includes a dust removal component 501, the dust removal component 501 is used to clean the wind wheel 400, and the dust removal component 501 is configured to be able to move along the axial direction of the wind wheel 400. Since the wind wheel 400 is arranged along the length direction of the air conditioner indoor unit 1000, the axial direction of the wind wheel 400 is Figure 1 The left and right directions of the air conditioner indoor unit 1000 shown in the figure are consistent, that is, the dust removal component 501 can move along the left and right directions, so that the entire wind wheel 400 can be cleaned.

[0058] It can be understood that the cleaning mechanism 500 also includes a first driving component 502, which is used to drive the dust removal component 501 to move. The first driving component 502 can use a motor or other power device as a power source, and the dust removal component 501 can use a brush, cleaning cotton or other forms of cleaning tools. During cleaning, the first driving component 502 can drive the dust removal component 501 to move left and right, which can remove dust and other dirt accumulated on the surface of the wind wheel 400, and the cleaning effect is good.

[0059] Reference Figure 2 and Figure 3 As shown, the air-conditioning indoor unit 1000 of the embodiment of the present invention also includes a dust collecting mechanism 600, and the dust collecting mechanism 600 includes a dust collecting trough 610. The dust collecting trough 610 is arranged on the air outlet side of the air duct structure 200. Considering that when the dust removal component 501 cleans the wind wheel 400, the swept dirt will fall along the air duct 201 toward the air outlet 211. In the embodiment, the dust collecting trough 610 is specifically arranged at the bottom of the air outlet 211. The fallen dirt can be collected by the dust collecting trough 610, which is convenient for cleaning the dirt.

[0060] Reference Figure 2 and Figure 3 As shown, a water receiving tank 215 is provided in the air-conditioning indoor unit 1000 , and the water receiving tank 215 is used to receive condensed water generated by the heat exchanger 300 . Specifically, the water receiving tank 215 is arranged near the rear side of the air-conditioning indoor unit 1000 and is located below the rear side of the heat exchanger 300 .

[0061] Reference Figure 4 As shown, the dust collecting mechanism 600 in the embodiment also includes a drainage structure 620, which connects the water receiving tank 215 and the dust collecting tank 610, and is used to drain the condensed water of the water receiving tank 215 to the dust collecting tank 610; the dust collecting tank 610 has a drainage structure, and the condensed water can be used to flush the dust collecting tank 610. The drainage structure can flush away the dirt collected in the dust collecting tank 610, and there is no need for manual operation to clean the dirt, thereby realizing automatic cleaning of the wind wheel 400, with high cleaning efficiency and better cleaning effect.

[0062] Compared with the dust removal method using suction in related arts, in the embodiment of the present invention, the water receiving trough 215, the drainage structure 620, the dust collecting trough 610 are connected with the drainage structure to form a drainage channel. The wind wheel 400 is cleaned by the dust removal component 501, and the dust collecting trough 610 is used to collect dust. Then, condensed water is flushed through the drainage channel to flush the dust collecting trough 610, thereby achieving the purpose of automatic dust cleaning. The implementation method is easier, less costly, and more practical and reliable.

[0063] It should be noted that, combined with Figure 2 It can be understood that, since the position of the water receiving tank 215 is higher than the dust collecting tank 610, the drainage structure 620 can be a drainage tank, a drainage pipe or other structures. For example, the water receiving tank 215 is directly connected to the dust collecting tank 610 by a drainage pipe, and the condensed water can be drained into the dust collecting tank 610. In addition, the drainage structure can be a drainage hole provided in the dust collecting tank 610, and the drainage hole can discharge water out of the air conditioner indoor unit 1000 through the drainage pipe; the drainage structure can also be a drainage pump, and the accumulated water in the dust collecting tank 610 is pumped away by the drainage pump.

[0064] Reference Figure 4 and Figure 5 As shown, the air duct structure 200 of the embodiment of the present invention includes a volute 210, an air duct 201 is formed in the volute 210, and a wind wheel 400 is rotatably connected to the volute 210. Figure 2 and Figure 3 It can be understood that the volute 210 has a volute tongue 213 and a first air duct wall 214 opposite to the volute tongue 213, wherein the dust collecting groove 610 is arranged at one end of the first air duct wall 214 away from the wind wheel 400, and dirt can fall into the dust collecting groove 610 along the first air duct wall 214 during the cleaning process; the drainage structure 620 is a flow channel 621 formed on the first air duct wall 214, and the water receiving groove 215 is provided with a water outlet 2151. The upper end of the flow channel 621 is connected to the water outlet 2151, and the lower end of the flow channel 621 is connected to the dust collecting groove 610, so that condensed water can flow along the flow channel 621 to the dust collecting groove 610.

[0065] Reference Figure 4 and Figure 6 As shown, in some embodiments, the flow channel 621 is arranged at the left end of the first air duct wall 214, and the flow channel 621 can be integrally formed with the volute 210. It can be understood that the wall surface of the first air duct wall 214 is recessed to form the flow channel 621, so that the flow channel 621 does not affect the operation of the wind wheel 400. Of course, this is only an example, and the flow channel 621 is not limited to being arranged at the left end of the first air duct wall 214, and can also be arranged at the right end of the first air duct wall 214, or the flow channel 621 can be arranged at the left end and the right end of the first air duct wall 214 at the same time, and the flow channels 621 at both ends are connected to the water receiving tank 215 and the dust collecting tank 610 respectively.

[0066] It should be noted that, refer to Figure 2 and Figure 3 As shown, in the embodiment, the water receiving trough 215 is arranged near the air inlet 212 of the volute 210. Specifically, the water receiving trough 215 is formed on the side of the first air duct wall 214 away from the wind wheel 400. The water receiving trough 215 can be integrally formed with the volute 210, and the structure is more reliable.

[0067] Reference Figure 2 and Figure 3 As shown, in some embodiments, the dust removal assembly 501 includes a first brush member 510, which is slidably disposed in the air duct 201 near the air outlet 211, and the first driving assembly 502 is used to drive the first brush member 510 to move along the length direction of the volute 210, so that the first brush member 510 can sweep the wind wheel 400 back and forth in the air duct 201.

[0068] Reference Figure 5 and Figure 7 As shown, specifically, the first brush member 510 is roughly flat, and the side of the first brush member 510 facing the wind wheel 400 is provided with a first arc portion 514 matching the outer contour of the wind wheel 400, and the first arc portion 514 is provided with a first brush portion 511, and the surface of the wind wheel 400 can be cleaned by the first brush portion 511. The first brush portion 511 can be made of wool, plastic wire or other materials, and the specific selection is based on actual usage requirements.

[0069] In the embodiment, the first drive assembly 502 includes a first motor 520 and a first worm 530. The first motor 520 is installed on the outer wall of the volute 210. The first worm 530 can be set in the air duct 201. The first motor 520 is drivingly connected to the first worm 530. The first worm 530 is drivingly connected to the first brush member 510. The first motor 520 can specifically be a stepping motor. The first brush member 510 can be provided with a threaded hole matching the first worm 530. When the first motor 520 drives the first worm 530 to rotate, it can drive the first brush member 510 to move along the first worm 530, thereby driving the first brush member 510 to clean the wind wheel 400.

[0070] It can be understood that the first worm 530 is extended along the length direction of the volute 210, so that the first brush member 510 can move back and forth in the air duct 201. The transmission is performed by the first worm 530, which has the characteristics of smooth transmission and high reliability, and can effectively improve the working stability of the first brush member 510.

[0071] It should be noted that, in the process of the first brush member 510 cleaning the wind wheel 400, the first motor 520 can be used to drive the first brush member 510 to move for cleaning through the first worm gear 530. At this time, the wind wheel 400 remains stationary. After moving back and forth several times, the wind wheel 400 is driven to rotate to a certain angle, and then the wind wheel 400 is continued to be cleaned. The operation is repeated in this way to clean the entire wind wheel 400. Alternatively, the wind wheel 400 can be driven to rotate synchronously when the first brush member 510 moves back and forth to achieve the purpose of cleaning the entire wind wheel 400. The specific cleaning method can be selected according to actual requirements.

[0072] Reference Figure 8 and Fig. 9 As shown, Figure 8 The front structure of the air-conditioning indoor unit 1000 is shown when the heat exchanger 300 and the wind wheel 400 are not installed. It can be understood that the first brush member 510 is provided with a first positioning portion 512 and a second positioning portion 513, wherein the first positioning portion 512 is slidably matched with the volute tongue 213, and the second positioning portion 513 is slidably matched with the first air duct wall 214. The first positioning portion 512 and the second positioning portion 513 are matched for positioning, so that the first brush member 510 can be confined in the air duct 201 and move more stably.

[0073] Specifically, the first arc portion 514 is located between the first positioning portion 512 and the second positioning portion 513, and the first worm gear 530 is connected to one end of the first brush member 510 away from the first brush portion 511; when the first brush member 510 moves driven by the first worm gear 530, the first positioning portion 512 and the second positioning portion 513 can be understood as supporting parts at both ends of the first brush member 510, and only one first worm gear 530 is required to maintain the stability of the movement of the first brush member 510, which can prevent the first brush member 510 from being offset, and there is no need to add an additional guide structure, thereby achieving lower cost.

[0074] Reference Fig. 9 As shown, the first positioning portion 512 is specifically a concave structure that matches the volute tongue 213, so that the first positioning portion 512 can fit tightly on the volute tongue 213 to achieve the purpose of positioning; the surface of the concave structure is provided with a plurality of first convex ribs 5121, and the plurality of first convex ribs 5121 are arranged at intervals. The first positioning portion 512 is in contact with the volute tongue 213 through the first convex ribs 5121, which is beneficial to reducing friction and improving movement stability; at the same time, it has a certain effect of cleaning the volute tongue 213.

[0075] Continue to refer to Fig. 9As shown, the second positioning portion 513 is specifically an arc-shaped structure matching the first air duct wall 214, so that the second positioning portion 513 can be closely attached to the first air duct wall 214. In some embodiments, the second positioning portion 513 is provided with a plurality of second convex ribs 5131, and the plurality of second convex ribs 5131 are arranged at intervals. The second positioning portion 513 abuts against the first air duct wall 214 through the second convex ribs 5131, thereby reducing friction.

[0076] In addition, a second brush portion 5132 is provided between adjacent second ribs 5131 in the embodiment. The second brush portion 5132 is made of the same material as the first brush portion 511 of the above embodiment. When the first brush member 510 moves along the air duct 201, the first air duct wall 214 can be cleaned by the second brush portion 5132, and dust accumulated on the first air duct wall 214 can be removed. In this way, the first brush member 510 can clean the wind wheel 400 and the first air duct wall 214 at the same time, with higher cleaning efficiency and better cleaning effect.

[0077] It can be understood that since the flow channel 621 is arranged on the first air duct wall 214, when the first brush member 510 moves along the left and right directions to clean the first air duct wall 214, the dust on the first air duct wall 214 can be swept into the flow channel 621, and the dust in the flow channel 621 can be flushed into the dust collecting tank 610 by using the water flow, so that the flow channel 621 and the dust collecting tank 610 can be flushed clean, thereby achieving the purpose of efficiently cleaning the wind wheel 400 and the air duct 201.

[0078] Reference Figure 5 and Figure 7 As shown, the first worm 530 and the dust collecting groove 610 are respectively arranged along the axial direction of the wind wheel 400, and the first worm 530 is arranged in the dust collecting groove 610, so that the first worm 530 does not occupy the space of the air duct 201, and the installation is more compact. The first worm 530 is provided with a movable slider 531, the slider 531 is threadedly connected to the first worm 530, and the slider 531 is detachably connected to the first brush member 510, which is convenient for disassembling, replacing or cleaning the first brush member 510.

[0079] Combination Fig. 9 It can be understood that the first worm 530 and the slider 531 are both located in the dust collecting tank 610, the slider 531 is provided with a slot 5311, and the first brush member 510 is provided with a connecting portion 515, which is arranged toward the dust collecting tank 610 and is buckled with the slot 5311, and is easy to assemble; when the first motor 520 drives the first worm 530 to rotate, the slider 531 can move along the first worm 530, thereby driving the first brush member 510 to move. During the cleaning process of the first brush member 510, dirt will be swept into the flow channel 621 and the dust collecting tank 610, and the dirt will be discharged by the water flow. The first worm 530 is separated from the bottom wall of the dust collecting tank 610, and does not affect the flushing of the water flow.

[0080] Reference Figure 2 and Figure 3 As shown, in some embodiments, the dust collecting mechanism 600 also includes a first cover plate 640 and a second motor 630. The first cover plate 640 is arranged along the length direction of the dust collecting trough 610. The first cover plate 640 is rotatably connected to the volute 210 near the dust collecting trough 610. The second motor 630 is drivingly connected to the first cover plate 640. For example, the first cover plate 640 is provided with a rotating shaft rotatably connected to the volute 210 at both ends along the length direction. The second motor 630 is drivingly connected to the rotating shaft. The first cover plate 640 can be driven by the second motor 630 to open or close the dust collecting trough 610.

[0081] Figure 2 The structure showing the first cover plate 640 is in a closed state. It can be understood that when the second motor 630 drives the first cover plate 640 to close, the first worm gear 530 can drive the first brush member 510 to move to the two ends of the air duct 201, so that the first brush member 510 does not affect the closing of the first cover plate 640, and the first worm gear 530 can be hidden in the dust collecting trough 610; of course, when the first cover plate 640 is closed, it can limit the first brush member 510, so that the first brush member 510 cannot move.

[0082] It should be noted that the width of the first cover plate 640 can be set according to the slot size of the dust collecting slot 610. When the first cover plate 640 closes the dust collecting slot 610, the first cover plate 640 covers the slot position of the dust collecting slot 610. The surface of the first cover plate 640 can smoothly transition with the surface of the first air duct wall 214, so that the first cover plate 640 will not protrude from the wall surface of the first air duct wall 214. The first cover plate 640 becomes a part of the first air duct wall 214, reducing wind resistance.

[0083] Figure 3 The structure in which the first cover plate 640 is in an open state is shown. It can be understood that when cleaning is required, the second motor 630 drives the first cover plate 640 to open. At this time, the first brush member 510 can move along the dust collecting groove 610 driven by the first worm 530, and the first cover plate 640 does not affect the movement of the first brush member 510; in addition, when the first cover plate 640 is opened, it is located on the side of the dust collecting groove 610 away from the second positioning portion 513, which can block dust to a certain extent and facilitate dust collection. In some embodiments, the width of the first cover plate 640 is designed to be close to the width of the air outlet 211, and can block the air outlet 211 when in the open state, and can prevent dust from splashing to the outside of the air duct 201.

[0084] Considering that the first worm gear 530 is installed in the dust collecting trough 610, and the first worm gear 530 is detachably connected to the first brush member 510, in some embodiments, the first worm gear 530, the dust collecting trough 610, the first cover plate 640, the first motor 520 and the second motor 630 can be combined to form an integral module structure. The entire module structure can be detachably installed at the air outlet 211 of the volute 210, which is easy to install and maintain.

[0085] Reference Figure 5 As shown, in some embodiments, it can be understood that the side wall along the length direction of the volute 210 is the second air duct wall 216, wherein the second air duct wall 216 on the right side of the volute 210 is provided with a groove 2161, and the groove 2161 matches the shape of the first brush member 510. After the cleaning work is completed, the first brush member 510 is driven by the first motor 520 to enter the groove 2161, and the first brush member 510 is stored in the groove 2161, so that the first brush member 510 can be hidden; then the first cover plate 640 is controlled to be closed, so that the first brush member 510 will not move into the air duct 201, and will not affect the normal operation of the air-conditioning indoor unit 1000.

[0086] Of course, this is only an example, and the groove 2161 is not limited to being set on the second air duct wall 216 on the right side of the volute 210, and can also be set on the second air duct wall 216 on the left side, which can be selected according to actual application requirements. In addition, the position of the groove 2161 can be set as the initial position of the first brush member 510, so as to facilitate the initialization positioning of the moving stroke of the first brush.

[0087] Reference Fig.10 and Fig.11 As shown, in some embodiments, the dust removal component 501 includes a second brush member 540, which is slidably set at the air inlet 212 position of the air duct structure 200, and the second brush member 540 is used to clean the wind wheel 400.

[0090] It can be understood that the second worm 560 is extended along the length direction of the wind wheel 400, and the second worm 560 drives the second brush member 540 to move back and forth, so that the entire wind wheel 400 can be cleaned. Fig.11 and Fig.12 In the illustrated embodiment, the second brush member 540 is disposed on a side of the volute 210 close to the volute tongue 213. Compared with the structure of the first brush member 510 installed in the air duct 201, the gap between the heat exchanger 300 and the wind wheel 400 can be effectively utilized, and the installation is compact. The heat exchanger 300 can be used to limit the second brush member 540, so that the second brush member 540 can operate more stably.

[0091] In some embodiments, a first brush member 510 and a second brush member 540 may be provided in the air conditioner indoor unit 1000 at the same time. It can be understood that the first brush member 510 and the second brush member 540 are respectively provided on both sides of the wind wheel 400, and the wind wheel 400 can be cleaned at the same time, thereby greatly improving the cleaning efficiency.

[0092] Reference Fig.11 and Fig.12 As shown, in some embodiments, the second driving assembly also includes a guide rod 570, one end of the second brush member 540 is connected to the second worm gear 560, and the other end is slidably connected to the guide rod 570, and the guide rod 570 is arranged parallel to the second worm gear 560. The guide rod 570 guides the second brush member 540, can keep the two ends of the second brush member 540 balanced, and can further improve the stability of the movement of the second brush member 540.

[0093] In the embodiment, one guide rod 570 is provided, and the second worm 560 is located above the guide rod 570, that is, the second worm 560 is connected to the upper end of the second brush member 540, and the guide rod 570 is connected to the lower end of the second brush member 540. This is only an example, and the positions of the second worm 560 and the guide rod 570 can also be replaced; in addition, the number of guide rods 570 is not limited to one, and is specifically selected according to the width of the second brush member 540. The larger the width of the second brush member 540, the more two or more guide rods 570 can be used to guide the second brush member 540, and the reliability is higher.

[0094] Reference Fig.11 and Fig.12 As shown, the dust collecting mechanism 600 in the embodiment further includes a second cover plate 660 and a fourth motor 650. The second cover plate 660 is arranged along the length direction of the dust collecting groove 610. The second cover plate 660 is rotatably connected to the position of the volute 210 near the dust collecting groove 610. The fourth motor 650 is driven and connected to the second cover plate 660. For the specific connection structure, see Figure 2 and Figure 3 The second motor 630 is connected to the first cover plate 640 in the embodiment. The second cover plate 660 can be driven by the fourth motor 650 to open or close the dust collecting tank 610.

[0095] Fig.11 The structure of the second cover 660 is shown in a closed state. When the second cover 660 is closed, the second cover 660 covers the notch of the dust collecting groove 610, and the surface of the second cover 660 can smoothly transition with the surface of the first air duct wall 214, so that the second cover 660 will not protrude from the wall surface of the first air duct wall 214, that is, the second cover 660 becomes a part of the first air duct wall 214, reducing wind resistance.

[0096] Specifically, in the embodiment, the width of the second cover plate 660 is greater than the slot width of the dust collecting slot 610, and an accommodating portion is provided on the surface of the first air duct wall 214 near the dust collecting slot 610. The accommodating portion may be an accommodating slot matching the second cover plate 660. When the second cover plate 660 is closed, the second cover plate 660 may be received in the accommodating slot, thereby achieving the purpose of hiding the second cover plate 660 without affecting the air outlet of the air duct 201.

[0097] Fig.12 The structure of the second cover 660 is shown in an open state. It can be understood that since the installation position of the second brush member 540 is arranged opposite to the first air duct wall 214, the dust will fall downward along the volute tongue 213 when the second brush member 540 is cleaning. In order to allow the dirt to fall into the dust collecting trough 610, the second cover 660 in the embodiment is configured so that when the dust collecting trough 610 is opened, one end of the second cover 660 faces the dust collecting trough 610, and the other end abuts against the volute tongue 213, so that the dirt can slide along the second cover 660 into the dust collecting trough 610. At the same time, the second cover 660 can close the air outlet 211, so as to prevent dust from falling to the outside of the air duct 201.

[0098] In the embodiment, since a flow channel 621 connecting the water receiving groove 215 and the dust collecting groove 610 is provided on the first air duct wall 214, water is guided to the dust collecting groove 610 through the flow channel 621, which can wash away the dirt cleaned by the second brush member 540, and automatically clean the wind wheel 400 without manual cleaning of the dirt.

[0099] It should be noted that the width of the second cover 660 can be set according to the size of the air outlet 211. When the dust collecting trough 610 is opened, the second cover 660 can block the air outlet 211 and abut against the volute tongue 213, so as to guide the dirt to fall into the dust collecting trough 610. The design is reasonable. After the wind wheel 400 is cleaned, the second cover 660 can be stored without affecting the normal use of the air conditioning indoor unit 1000.

[0100] In addition, in the embodiment, the dust collecting groove 610 and the volute 210 can adopt an integrally formed structure. Specifically, the dust collecting groove 610 is formed at the end of the first air duct wall 214 away from the wind wheel 400, which is easy to manufacture and helps to reduce costs.

[0101] The embodiment of the present invention further proposes an air conditioner, including the air conditioner indoor unit 1000 of the above embodiment, the air conditioner indoor unit 1000 can clean the entire wind wheel 400 through the dust removal component 501, and use the dust collecting trough 610 of the dust collecting mechanism 600 to collect the cleaned dirt; because the water receiving trough 215 can receive the condensed water of the heat exchanger 300, the water receiving trough 215 is connected with the dust collecting trough 610 through the drainage structure 620, and the water in the water receiving trough 215 is drained to the dust collecting trough 610, so that the dirt collected in the dust collecting trough 610 can be washed away, and no manual operation is required, so that the wind wheel 400 can be automatically cleaned, the cleaning efficiency is high, the cleaning effect is better, and the user experience is better.

[0102] Since the air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
