[0074] Embodiments of the present application are described below in detail with reference to the accompanying drawings, wherein the same or similar components have the same or similar designations throughout the various figures. The embodiments described below are exemplary only, and are not to be construed as limiting the present application.

[0075] The air conditioner indoor unit 20 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0076] Referring to Figures 1-4 According to the air conditioner indoor unit 20 of the first aspect of the present application, the air conditioner indoor unit 20 can be installed in the interior of the cabinet 10, and the air conditioner indoor unit 20 includes a casing 2, a heat exchanger assembly 3, and a fan assembly 4. When the air conditioner indoor unit 20 is installed in the cabinet 10, an outer wall of the casing 2 is adapted to define an air inlet cavity 12 in communication with the exterior with an inner wall of the cabinet 10. A first air inlet 211 is formed in the casing 2 in communication with the air inlet cavity 12. An air outlet 221 is formed in a front side of the casing 2. The heat exchanger assembly 3 and the fan assembly 4 are both disposed in the casing 2. For example, the cabinet 10 has a receiving cavity 11 therein, and the air conditioner indoor unit 20 can be installed in the receiving cavity 11 of the cabinet 10. The outer wall of the casing 2 and the inner wall of the receiving cavity 11 define the air inlet cavity 12 therebetween.

[0077] When the air conditioner indoor unit 20 is installed in the cabinet 10, the fan assembly 4 can drive external air to enter the air inlet cavity 12 when the air conditioner indoor unit 20 is in operation. The air entering the air inlet cavity 12 enters the casing 2 of the air conditioner indoor unit 20 through the first air inlet 211. The air entering the casing 2 exchanges heat with the heat exchanger assembly 3 in the casing 2. The airflow after heat exchange is blown out of the air outlet 221 to the interior, thereby adjusting the temperature of the interior, for example, increasing or decreasing the temperature of the interior. The air flowing through the air conditioner indoor unit 20 can exchange heat with the heat exchanger assembly 3, so that the temperature of the air blown out of the air outlet 221 is reduced or increased, thereby achieving the effect of cooling or heating, and further improving the temperature of the air in the interior. Since the air inlet cavity 12 is in communication with the exterior, and the first air inlet 211 is in communication with the air inlet cavity 12, the fan assembly 4 can cause the air conditioner indoor unit 20 to suck in sufficient air, ensuring the air inlet and air outlet of the air conditioner indoor unit 20, and facilitating the air inlet of the air conditioner indoor unit 20 so that the air conditioner indoor unit 20 can operate normally.

[0078] Referring to Figure 10In some specific embodiments of the present application, the casing 2 comprises a rear shell 21, a panel 22, a base 23 and a top cover 24, the panel 22 is connected with the rear shell 21, the panel 22 and the rear shell 21 are arranged on the base 23, and the top cover 24 is arranged on the top of the panel 22 and the rear shell 21. The first air inlet 211 can be formed on the side of the rear shell 21 facing the air inlet cavity 12, and the air outlet 221 is formed on the side of the panel 22 facing the front. When the air conditioner indoor unit 20 is working, the fan assembly 4 can suck the air entering the air inlet cavity 12 from the outside into the interior of the air conditioner indoor unit 20 from the first air inlet 211, so that the air can pass through the heat exchanger assembly 3 and exchange heat with the heat exchanger assembly 3, and then the air treated by the heat exchanger assembly 3 is discharged to the indoor environment from the air outlet 221, so as to adjust the indoor environment temperature.

[0079] With reference to Figure 10 In some specific embodiments of the present application, the fan assembly 4 comprises a motor 41 and a fan wheel 42, the fan wheel 42 can be a cross-flow fan wheel, the rotation axis of the fan wheel 42 can extend in the up-down direction, and the air outlet 221 can also extend in the up-down direction, so as to increase the air volume. For example, the motor 41 can be arranged above the fan wheel 42, and the motor 41 is connected with the fan wheel 42 to drive the fan wheel 42 to rotate. When the air conditioner indoor unit 20 is working, the motor 41 can drive the fan wheel 42 to rotate, the rotation of the fan wheel 42 can drive the air entering the air inlet cavity 12 to flow into the air conditioner indoor unit 20, and then drive the air flowing into the air conditioner indoor unit 20 to be discharged to the indoor environment from the air outlet 221, so as to adjust the indoor environment temperature. When the fan wheel 42 is a cross-flow fan wheel, more air can be driven to flow into the air conditioner indoor unit 20 in a unit time, the working efficiency of the fan assembly 4 is improved, and the overall performance of the air conditioner indoor unit 20 is improved.

[0080] With reference to Figure 10 and Figure 12 In some specific embodiments of the present application, the heat exchanger assembly 3 comprises a heat exchanger 31, an electric auxiliary heater 32 and a sealing plate 33, the electric auxiliary heater 32 and the heat exchanger 31 can be arranged along the flow direction of the air flow, and the sealing plate 33 can be arranged on at least one side of the heat exchanger 31. The sealing plate 33 can seal the gap between the heat exchanger 31 and the inner wall of the casing 2, reduce air leakage, so that the air entering from the first air inlet 211 is heated by the heat exchanger 31 before flowing to the air outlet 221. The heat exchanger 31 can further comprise a heat exchanger body 311 and a side plate 312 arranged on opposite sides of the heat exchanger body 311, and the side plate 312 of the heat exchanger 31 can be connected with the casing 2 to facilitate the installation and fixation of the heat exchanger 31 in the casing 2.

[0081] By setting the heat exchanger 31, the heat exchanger assembly 3 can raise or lower the temperature of the air flowing into the air conditioner indoor unit 20 from the outside, so that the air conditioner indoor unit 20 achieves the effect of heating or cooling. When the air conditioner indoor unit 20 is heating, by setting the electric auxiliary heating 32, the temperature of the air flowing into the air conditioner indoor unit 20 from the outside can be quickly raised in cooperation with the heat exchanger 31, thereby improving the heating performance of the air conditioner indoor unit 20.

[0082] For example, with reference to Figure 10 In some embodiments of the present application, at least a part of the heat exchanger assembly 3 can be located between the fan assembly 4 and the first air inlet 211. When the air conditioner indoor unit 20 is working, the external air is driven by the fan assembly 4 into the air inlet cavity 12, and the air entering the air inlet cavity 12 flows into the interior of the air conditioner indoor unit 20 from the first air inlet 211, and can exchange heat with the heat exchanger assembly 3, and then be driven by the fan assembly 4 to blow out from the air outlet 221. In this way, the air flowing into the interior of the air conditioner indoor unit 20 can be fully exchanged with the heat exchanger assembly 3, thereby improving the heat exchange efficiency.

[0083] With reference to 8, Figure 9 , Figure 10 and Figure 13 In some embodiments of the present application, the air conditioner indoor unit 20 can further include a wind guide assembly, the wind guide assembly including: a first wind guide mechanism 61 and a second wind guide mechanism 62, the first wind guide mechanism 61 and the second wind guide mechanism 62 are arranged in the air outlet direction, and the first wind guide mechanism 61 can be arranged on the upstream side of the second wind guide mechanism 62 in the air outlet direction.

[0084] The second air guide mechanism 62 comprises a second connecting rod and a plurality of second louvers 621, the plurality of second louvers 621 can be arranged at intervals in the left-right direction, the second connecting rod can extend in the left-right direction, each second louver 621 is rotatably connected with the second connecting rod, the air conditioner indoor unit 20 can comprise a second driving mechanism for driving the second connecting rod to move back and forth in the left-right direction, when the second connecting rod moves in the left-right direction, the plurality of second louvers 621 can be swung in the left-right direction. For example, the first connecting rod 611 can drive the plurality of first louvers 612 to swing in the up-down direction, so that the air can change the flow direction in the up-down direction at the first air guide mechanism 61, so that the air blown out from the air outlet 221 can realize the adjustment in the up-down direction. The second connecting rod can drive the plurality of second louvers 621 to swing in the left-right direction, so that the air can change the flow direction in the left-right direction at the second air guide mechanism 62, so that the air blown out from the air outlet 221 can realize the adjustment in the left-right direction. The first air guide mechanism 61 and the second air guide mechanism 62 are matched, so that the air blown out from the air outlet 221 can realize multi-angle blowing, improving the comfort of the user.

[0085] It should be explained that in the description of the present application, the meaning of "a plurality of" is two or more than two.

[0086] Referring to Figure 9 As shown in the figure, in some embodiments of the present application, the air conditioner indoor unit 20 can further comprise a protective net 9 arranged on the downstream side of the fan wheel 42. For example, the protective net 9 can be arranged between the fan wheel 42 and the air guide assembly, or the protective net 9 can be arranged at the air outlet 221 and located on the downstream side of the air guide assembly. In this way, foreign matter can be prevented from falling into the interior of the air conditioner indoor unit 20 to affect the operation of the fan wheel 42 or damage the fan wheel 42, and the fingers of children can also be prevented from being inserted into the air conditioner indoor unit 20 to be injured by the fan wheel 42, thereby improving the safety performance of the air conditioner indoor unit 20.

[0087] The air conditioner indoor unit 20 according to the embodiments of the present application is installed in the cabinet 10, so that the outer wall of the casing 2 and the inner wall of the cabinet 10 define an air inlet cavity 12 communicating with the outside, and the first air inlet 211 is formed on the casing 2 and communicates with the air inlet cavity 12, so that the air conditioner indoor unit 20 can be hidden in the cabinet 10, the additional space occupied by the air conditioner indoor unit 20 can be reduced, the air conditioner indoor unit 20 will not be conspicuous in the whole home environment, and the air inlet function of the air conditioner indoor unit 20 is not affected, so that the air conditioner indoor unit 20 can operate normally.

[0088] Referring to Figure 2 and Figure 4According to some embodiments of the present application, the front side of the air inlet cavity 12 is formed with a vent 121 which communicates the first air inlet 211 with the outside, and the vent 121 is defined by the cabinet 2 and the cabinet body 10. By arranging the vent 121 on the front side of the air inlet cavity 12, air can be drawn from the front side of the cabinet body 10 through the vent 121 when the air conditioner indoor unit 20 is in operation. Since the vent 121 is defined by the cabinet 2 and the cabinet body 10, the space of the cabinet body 10 can be saved, and the cabinet body 10 can be made more compact, thereby saving the space occupied by the air conditioner indoor unit 20.

[0089] With reference to Figures 1-4 According to some embodiments of the present application, the vent 121 is provided with a ventilation grille 15. By arranging the ventilation grille 15, the air inlet cavity 12 can be hidden, and the cabinet body 10 and the air conditioner indoor unit 20 can look more coordinated and beautiful. Moreover, by arranging the ventilation grille 15, the amount of dust entering the cabinet body 10 and the air conditioner indoor unit 20 can be reduced, and the frequency of cleaning the air conditioner indoor unit 20 can be lowered.

[0090] For example, as shown in Figures 1-4 In some embodiments of the present application, the ventilation grille 15 can communicate the air inlet cavity 12 with the outside. For example, the ventilation grille 15 can be provided with a plurality of air inlet holes 151 which are generally in the shape of long strips extending in the left-right direction, and the plurality of air inlet holes 151 can communicate the air inlet cavity 12 with the outside. By arranging the ventilation grille 15, the air inlet cavity 12 can be hidden, and the cabinet body 10 and the air conditioner indoor unit 20 can look more coordinated and beautiful. When the air conditioner indoor unit 20 is in operation, the air inlet cavity 12 can still be connected with the outside through the air inlet holes 151 of the ventilation grille 15, so that the air conditioner indoor unit 20 can draw sufficient air from the outside, and the overall performance of the air conditioner indoor unit 20 can not be affected due to insufficient air intake, thereby ensuring that the air conditioner indoor unit 20 can still operate normally.

[0091] With reference to Figures 1-4According to some embodiments of the present application, the ventilation grille 15 is movably arranged at the ventilation opening 121 to open and close the ventilation opening 121. By movably arranging the ventilation grille 15 at the ventilation opening 121, it is convenient to clean the air inlet cavity 12 and to maintain the air conditioner indoor unit 20. For example, in the normal case (when the air conditioner indoor unit 20 can be in the working state or in the shutdown state), the ventilation grille 15 is arranged at the position to close the ventilation opening 121; when it is necessary to clean the air inlet cavity 12 or to maintain the components near the first air inlet 211 of the air conditioner indoor unit 20 or to maintain the air conditioner indoor unit 20 as a whole, the ventilation grille 15 can be moved to the position to open the ventilation opening 121.

By arranging the reinforcing flange 213 on the left and right sides of the rear shell 21, the structural strength of the rear shell 21 can be improved, and the connection between the rear shell 21 and the air duct component 5 is more reliable.

[0124] For example, as Figures 10-13As shown, in some embodiments of the present application, the left and right sides of the rear shell 21 are each formed with a reinforcing flange 213. The reinforcing flange 213 on the right side includes a first assembly surface 2133 and a second assembly surface 2134, which are arranged substantially perpendicularly, the first assembly surface 2133 faces to the right, and the second assembly surface 2134 faces to the rear. The reinforcing flange 213 on the left side includes a third assembly surface 2135, which faces to the right. The first assembly surface 2133 and the third assembly surface 2135 of the reinforcing flange 213 are each formed with a plurality of clamping holes 2132, which are arranged in the up-down direction. The air duct component 5 is formed with a plurality of buckles 222 on the left and right sides thereof, which are in one-to-one correspondence with the clamping holes 2132 and have the same number.

[0125] The third assembly surface 2135 of the reinforcing flange 213 is further formed with an eleventh fastening hole 2139, and the left side of the air duct component 5 is formed with a twelfth fastening hole 517 in one-to-one correspondence with the eleventh fastening hole 2139 and having the same number, and the sixth fastener is arranged in the eleventh fastening hole 2139 and the twelfth fastening hole 517, so that the air duct component 5 can be fixed to the rear shell 21 by the fifth fastener and the sixth fastener. The fifth fastener and the sixth fastener can be screws. When assembling the air conditioner indoor unit 20, the positioning hole 331 on the heat exchanger assembly 3 can be matched with the positioning protrusion 2131 on the reinforcing flange 213 first, and then the third fastener and the fourth fastener are used to fix the heat exchanger assembly 3 to the reinforcing flange 213, and then the buckle 222 of the air duct component 5 is matched with the clamping hole 2132 of the reinforcing flange 213, and finally the fifth fastener and the sixth fastener are used to fix the air duct component 5 to the reinforcing flange 213.

[0126] For example, as Figures 10-13As shown, in some embodiments of the present application, the left and right sides of the rear shell 21 can be formed with reinforcing flanges 213. The reinforcing flange 213 on the right side includes a first assembly surface 2133 and a second assembly surface 2134, which are arranged substantially perpendicularly, the first assembly surface 2133 faces to the right, and the second assembly surface 2134 faces to the rear. The reinforcing flange 213 on the left side includes a third assembly surface 2135, which faces to the right. The second assembly surface 2134 and the third assembly surface 2135 of the reinforcing flange 213 are respectively formed with positioning protrusions 2131, and the edge plate 312 and the sealing plate 33 of the heat exchanger assembly 3 are respectively formed with positioning holes 331 corresponding to the positioning protrusions 2131. The sealing plate 33 of the heat exchanger assembly 3 is also formed with a clearance hole 332 corresponding to the clamping hole 2132, which is used to avoid the buckle 222. In this way, the sealing plate 33 can avoid blocking the opening of the clamping hole 2132, so that the buckle 222 is difficult to assemble into the clamping hole 2132, and the assembly of the air duct component 5 and the rear shell 21 is more convenient, and the disassembly of the air duct component 5 and the rear shell 21 is facilitated.

[0127] The sixth fastener can be arranged in the seventh fastening hole 334, the eighth fastening hole 2137 and the twelfth fastening hole 517. When the heat exchanger assembly 3 is fixed, the seventh fastening hole 334 and the eighth fastening hole 2137 corresponding to the twelfth fastening hole 517 can not be arranged with fasteners; when the air duct component 5 is assembled with the rear shell 21, the sixth fastener is arranged in the seventh fastening hole 334, the eighth fastening hole 2137 and the twelfth fastening hole 517 to fix the air duct component 5 and the heat exchanger assembly 3 on the rear shell 21.
