[0076] 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.

[0077] The air conditioner indoor unit 20 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0078] Reference Figure 1-Figure 4 According to the air conditioner indoor unit 20 of the first embodiment of the present invention, the air conditioner indoor unit 20 can be installed inside 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, the outer wall of the casing 2 is suitable for defining an air inlet cavity 12 communicating with the outside between the inner wall of the cabinet 10, a first air inlet 211 communicating with the air inlet cavity 12 is formed on the casing 2, an air outlet 221 is formed on the front side of the casing 2, and the heat exchanger assembly 3 and the fan assembly 4 are both arranged in the casing 2. For example, the cabinet 10 has a receiving cavity 11, and the air conditioner indoor unit 20 can be installed in the receiving cavity 11 of the cabinet 10, and the air inlet cavity 12 is defined between the outer wall of the casing 2 and the inner wall of the receiving cavity 11.

[0079] After the air conditioner indoor unit 20 is installed on the cabinet 10, when the air conditioner indoor unit 20 is working, the fan assembly 4 can drive the external air into the air inlet cavity 12, and 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, and the airflow after heat exchange is blown out to the room from the air outlet 221, so that the temperature of the indoor environment can be adjusted, for example, the indoor environment temperature can be increased or decreased. Among them, 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 from the air outlet 221 is reduced or increased, thereby achieving the effect of cooling or heating, and then improving the indoor gas temperature. Since the air inlet chamber 12 is connected to the outside and the first air inlet 211 is connected to the air inlet chamber 12, the fan assembly 4 can enable the air-conditioning indoor unit 20 to inhale sufficient air, ensuring the air intake and air outlet of the air-conditioning indoor unit 20, and facilitating the air intake of the air-conditioning indoor unit 20 so that the air-conditioning indoor unit 20 can operate normally.

[0080] Reference Fig.10 In some specific embodiments of the present invention, the housing 2 includes a rear housing 21, a panel 22, a base 23 and a top cover 24, the panel 22 is connected to the rear housing 21, the panel 22 and the rear housing 21 are both arranged on the base 23, and the top cover 24 is arranged on the top of the panel 22 and the rear housing 21. The first air inlet 211 can be formed on the side of the rear housing 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 will 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 perform heat exchange with the heat exchanger assembly 3, and then the air processed by the heat exchanger assembly 3 is discharged into the room from the air outlet 221, thereby adjusting the indoor ambient temperature.

[0081] Reference Fig.10 In some specific embodiments of the present invention, the fan assembly 4 includes a motor 41 and a wind wheel 42. The wind wheel 42 may be a cross-flow wind wheel. The rotation axis of the wind wheel 42 may extend in the up-down direction. The air outlet 221 may also extend in the up-down direction, thereby increasing the air volume. For example, the motor 41 may be arranged above the wind wheel 42, and the motor 41 is connected to the wind wheel 42 to drive the wind wheel 42 to rotate. When the air conditioner indoor unit 20 is working, the motor 41 may drive the wind wheel 42 to rotate. The rotation of the wind wheel 42 may 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 from the air outlet 221 to the room, thereby adjusting the indoor ambient temperature. When the wind wheel 42 is a cross-flow wind wheel, more air may be driven to flow into the air conditioner indoor unit 20 per unit time, thereby improving the working efficiency of the fan assembly 4 and improving the overall performance of the air conditioner indoor unit 20.

[0082] Reference Fig.10 and Fig.12 In some specific embodiments of the present invention, the heat exchanger assembly 3 includes: a heat exchanger 31, an electric auxiliary heat 32 and a sealing plate 33. The electric auxiliary heat 32 and the heat exchanger 31 can be arranged along the flow direction of the airflow. 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 to reduce air leakage, so that the air entering from the first air inlet 211 is heat exchanged through the heat exchanger 31 before flowing to the air outlet 221. The heat exchanger 31 can also include a heat exchanger body 311 and a side plate 312. The side plates 312 are arranged on opposite sides of the heat exchanger body 311. The side plates 312 of the heat exchanger 31 can be connected to the casing 2 to facilitate the installation and fixing of the heat exchanger 31 into the casing 2.

[0083] By providing the heat exchanger 31, the heat exchanger assembly 3 can increase or decrease the temperature of the air flowing from the outside into the air conditioner indoor unit 20, so that the air conditioner indoor unit 20 can achieve a heating or cooling effect. When the air conditioner indoor unit 20 is heating, by providing the electric auxiliary heat 32, the temperature of the air flowing from the outside into the air conditioner indoor unit 20 can be quickly increased in cooperation with the heat exchanger 31, thereby improving the heating performance of the air conditioner indoor unit 20.

[0084] For example, refer to Fig.10 In some specific embodiments of the present invention, at least a portion of the heat exchanger assembly 3 may 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 to enter the air inlet cavity 12. When 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, it can exchange heat with the heat exchanger assembly 3, and then be driven by the fan assembly 4 to be blown out from the air outlet 221. In this way, the air flowing into the interior of the air conditioner indoor unit 20 can fully exchange heat with the heat exchanger assembly 3, thereby improving the heat exchange efficiency.

[0085] Refer to 8. Fig. 9 , Fig.10 and Fig.13 In some specific embodiments of the present invention, the air conditioner indoor unit 20 may further include an air guide assembly, the air guide assembly including: a first air guide mechanism 61 and a second air guide mechanism 62, the first air guide mechanism 61 and the second air guide mechanism 62 are arranged at intervals along the air outlet direction, and the first air guide mechanism 61 may be arranged at the upstream side of the second air guide mechanism 62 along the air outlet direction. The first air guide mechanism 61 includes a first connecting rod 611 and a plurality of first louvers 612, the plurality of first louvers 612 may be arranged at intervals along the up-down direction, the first connecting rod 611 may extend along the up-down direction, each first louver 612 is rotatably connected to the first connecting rod 611, and the air conditioner indoor unit 20 may include a first driving mechanism for driving the first connecting rod 611 to reciprocate up and down, and when the first connecting rod 611 moves in the up-down direction, the plurality of first louvers 612 may be driven to swing in the up-down direction.

[0086] The second air guide mechanism 62 includes 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 to the second connecting rod, and the air conditioner indoor unit 20 can include a second driving mechanism for driving the second connecting rod to move back and forth left and right, and when the second connecting rod moves in the left-right direction, the plurality of second louvers 621 can be driven to swing 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 wind blown out from the air outlet 221 can be adjusted 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 wind blown out from the air outlet 221 can be adjusted in the left-right direction. The first air guiding mechanism 61 and the second air guiding mechanism 62 cooperate with each other so that the air blown out from the air outlet 221 can be blown at multiple angles, thereby improving the comfort of the user.

[0087] It should be explained that, in the description of the present invention, “plurality” means two or more than two.

[0088] Reference Fig. 9 As shown, in some specific embodiments according to the present invention, the air conditioner indoor unit 20 may further include: a protective net 9, which is arranged on the downstream side of the wind wheel 42. For example, the protective net 9 may be arranged between the wind wheel 42 and the wind guide assembly, or the protective net 9 may be arranged at the air outlet 221 and on the downstream side of the wind guide assembly. In this way, foreign objects may be prevented from falling into the interior of the air conditioner indoor unit 20 and affecting the operation of the wind wheel 42 or damaging the wind wheel 42, and children may be prevented from inserting their fingers into the air conditioner indoor unit 20 and being injured by the wind wheel 42, thereby improving the safety performance of the air conditioner indoor unit 20.

[0089] According to the air-conditioning indoor unit 20 of the embodiment of the present invention, the air-conditioning indoor unit 20 is installed inside the cabinet 10, so that an air inlet chamber 12 connected to the outside is defined between the outer wall of the casing 2 and the inner wall of the cabinet 10, and a first air inlet port 211 connected to the air inlet chamber 12 is formed on the casing 2, so that the air-conditioning indoor unit 20 can be hidden in the cabinet 10, and the additional space occupied by the air-conditioning indoor unit 20 can be reduced. It will not appear abrupt in the entire home environment, and will not affect the air intake function of the air-conditioning indoor unit 20, so that the air-conditioning indoor unit 20 can operate normally.

[0090] Reference Figure 2 and Figure 4According to some embodiments of the present invention, a vent 121 is formed at the front side of the air inlet cavity 12, which communicates with the first air inlet 211 and the outside, and the vent 121 is defined by the housing 2 and the cabinet 10. By arranging the vent 121 at the front side of the air inlet cavity 12, when the air conditioner indoor unit 20 is working, air can be introduced from the front side of the cabinet 10 through the vent 121. Among them, since the vent 121 is defined by the housing 2 and the cabinet 10, the space of the cabinet 10 can be saved, making the cabinet 10 more compact, thereby saving the space occupied by installing the air conditioner indoor unit 20.

[0091] Reference Figure 1-Figure 4 According to some embodiments of the present invention, a ventilation grille 15 is provided at the vent 121. By providing the ventilation grille 15, the air inlet cavity 12 can be hidden, so that the cabinet 10 and the air conditioner indoor unit 20 look more coordinated and beautiful. In addition, by providing the ventilation grille 15, dust can be reduced from entering the cabinet 10, and dust can also be reduced from entering the air conditioner indoor unit 20 from the first air inlet 211, thereby reducing the frequency of cleaning the air conditioner indoor unit 20.

[0092] For example, Figure 1-Figure 4 As shown, in some specific embodiments of the present invention, the ventilation grille 15 can connect the air inlet chamber 12 with the outside. For example, the ventilation grille 15 has a plurality of air inlet holes 151, and the air inlet holes 151 are generally in the shape of a long strip extending in the left-right direction, and the plurality of air inlet holes 151 can connect the air inlet chamber 12 with the outside. By providing the ventilation grille 15, the air inlet chamber 12 can be hidden, so that the cabinet 10 and the air conditioner indoor unit 20 look more coordinated and beautiful. When the air conditioner indoor unit 20 is in operation, by providing the air inlet holes 151 on the ventilation grille 15, the air inlet chamber 12 can still be connected to the outside through the air inlet holes 151, so that the air conditioner indoor unit 20 can inhale sufficient air from the outside, avoiding affecting the overall performance of the air conditioner indoor unit 20 due to insufficient air intake, so that the air conditioner indoor unit 20 can still operate normally.

[0093] Reference Figure 1-Figure 4According to some embodiments of the present invention, the ventilation grille 15 is movably disposed at the vent 121 to open and close the vent 121. By movably disposing the ventilation grille 15 at the vent 121, it is convenient to clean the air inlet cavity 12 and to maintain the air conditioner indoor unit 20. For example, under normal circumstances (the air conditioner indoor unit 20 can be in a working state or in a shutdown state), the ventilation grille 15 is in a position to close the vent 121; after the air conditioner indoor unit 20 has been used for a long time, if 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 a position to open the vent 121.

[0094] When disassembling the air conditioner indoor unit 20, the ventilation grille 15 is moved to open the ventilation port 121, which can expand the operating space of the disassembling personnel, and it is not only convenient to install the air conditioner indoor unit 20 into the cabinet 10, but also convenient to disassemble the air conditioner indoor unit 20 from the cabinet 10. When the air conditioner needs to be repaired, the maintenance personnel can first move the ventilation grille 15 away from the ventilation port 121 to open the ventilation port 121, and then perform maintenance operations on the air conditioner indoor unit 20. After the maintenance of the air conditioner indoor unit 20 is completed, the ventilation grille 15 is moved back to the ventilation port 121 to close the ventilation port 121, which is convenient for the maintenance of the air conditioner indoor unit 20.

[0095] Reference Figure 2-Figure 4 According to some embodiments of the present invention, the ventilation grille 15 is rotatably connected to the housing 2 or the cabinet 10.

For example, the ventilation grille 15 can be fixed to the cabinet 10 at the vent 121 by fasteners. For another example, when the ventilation grille 15 is rotatably connected to the housing 2 or the cabinet 10, the ventilation grille 15 can also be detachably connected to the housing 2 or the cabinet 10. By detachably providing the ventilation grille 15 at the vent 121, it is convenient to disassemble and replace the ventilation grille 15, and it is also convenient to maintain the air inlet chamber 12 and the air conditioner indoor unit 20.

Thus, the first air inlet 211 on the housing 2 can be directly opposite to the air inlet cavity 12, so that the air flowing into the air inlet cavity 12 directly flows into the housing 2 through the first air inlet 211, reducing the flow path and flow resistance of the air flowing from the air inlet cavity 12 to the first air inlet 211, reducing the air inlet noise, and making the overall structure compact.

[0099] Reference Figure 2-Figure 4 According to some embodiments of the present invention, the air inlet cavity 12 is located on the left and right sides of the housing 2, and a first air inlet 211 is formed on the left side wall of the air inlet cavity 12 of the housing 2 facing the left side, and a first air inlet 211 is formed on the right side wall of the air inlet cavity 12 of the housing 2 facing the right side.

The air inlet cavity 12 is located on the left or right side of the housing 2, and the first air inlet 211 and the second air inlet 212 are adjacent to each other, which can not only increase the air intake of the air conditioner indoor unit 20, but also make the first air inlet 211 and the second air inlet 212 both located on the same side of the air outlet 221, so that the air intake position is relatively concentrated, thereby reducing the mutual influence between the air inlet and the air outlet, and can also simplify the internal structure of the air conditioner indoor unit 20, can improve the working efficiency of the fan assembly 4, and reduce the manufacturing cost of the air conditioner indoor unit 20.

[0102] Reference Figure 8-Figure 11 According to some embodiments of the present invention, the first air inlet 211, the second air inlet 212 and the air outlet 221 all extend in the up-down direction. The first air inlet 211 and the second air inlet 212 extend in the up-down direction, which can expand the air inlet area of ​​the first air inlet 211 and the second air inlet 212, increase the air inlet volume of the air conditioner indoor unit 20, and improve the air processing efficiency of the heat exchanger assembly 3. The air outlet 221 extends in the up-down direction, which can expand the air outlet area of ​​the air outlet 221, increase the air outlet volume of the air conditioner indoor unit 20, and discharge the air processed by the heat exchanger assembly 3 from the air conditioner indoor unit 20 as soon as possible, quickly adjust the indoor ambient temperature, improve the overall performance of the air conditioner, and improve the user experience.

[0103] Reference Figure 8-Figure 11 According to some embodiments of the present invention, the plane where the second air inlet 212 is located is located in front of the plane where the air outlet 221 is located. By locating the plane where the second air inlet 212 is located in front of the plane where the air outlet 221 is located, the second air inlet 212 and the air outlet 221 are staggered in the front-to-back direction, reducing the influence of the inlet and outlet winds between the second air inlet 212 and the air outlet 221, and locating the plane where the second air inlet 212 is located in front of the plane where the air outlet 221 is located, it is possible to better avoid that the wind sucked in from the second air inlet 212 is the wind discharged from the air outlet 221, thereby improving the working efficiency of the air conditioner indoor unit 20.

[0104] Reference Figure 1 , Figure 2 , Figure 4-Figure 6According to some embodiments of the present invention, the air conditioner indoor unit 20 includes: a switch door 7, which is movably provided on the housing 2 to open and close the air outlet 221.

The air conditioner indoor unit 20 can conveniently open and close the air outlet 221 by providing the switch door 7.

[0105] For example, when the air-conditioning indoor unit 20 is working, the switch door 7 can open the air outlet 221; when the air-conditioning indoor unit 20 is not working, the switch door 7 can close the air outlet 221 to reduce dust from entering the air outlet 221 into the air-conditioning indoor unit 20 and reduce the frequency of cleaning the air-conditioning indoor unit 20. Furthermore, when the switch door 7 is in a position to open the air outlet 221, at least a portion of the switch door 7 is arranged opposite to the second air inlet 212 and a plurality of ventilation holes 71 are formed on the portion of the switch door 7 opposite to the second air inlet 212, which can make the structure of the whole machine compact. Moreover, when the switch door 7 opens the air outlet 221, although at least a portion of the switch door 7 is arranged opposite to the second air inlet 212, a plurality of ventilation holes 71 are formed on the portion of the switch door 7 opposite to the second air inlet 212, so that external air can enter the second air inlet 212 through the plurality of ventilation holes 71 on the switch door 7, thereby ensuring the normal air intake of the second air inlet 212, thereby preventing the switch door 7 from blocking the second air inlet 212 and causing a reduction in the air intake of the air-conditioning indoor unit 20, thereby preventing the reduction in the air intake from affecting the air processing performance of the air-conditioning indoor unit 20, thereby allowing the air-conditioning indoor unit 20 to operate normally.

[0106] Reference Figure 1 , Figure 2 , Figure 4-Figure 6 According to some embodiments of the present invention, the air conditioner indoor unit 20 includes: a switch door 7, which is movably provided on the housing 2 to open and close the air outlet 221. When the switch door 7 is located at a position to close the air outlet 221, the switch door 7 is opposite to the air outlet 221 and the switch door 7 is opposite to at least a part of the second air inlet 212. The part of the switch door 7 opposite to the air outlet 221 and the part of the switch door 7 opposite to the second air inlet 212 are both formed with a plurality of ventilation holes 71. By providing the switch door 7, the air conditioner indoor unit 20 can conveniently realize the opening and closing of the air outlet 221. Moreover, when the switch door 7 is in the position of closing the air outlet 221, the switch door 7 is opposite to the air outlet 221 and the switch door 7 is opposite to at least a part of the second air inlet 212, and a plurality of ventilation holes 71 are formed on the part of the switch door 7 opposite to the air outlet 221 and the part of the switch door 7 opposite to the second air inlet 212, so that a windless mode can be realized, so that the air-conditioning indoor unit 20 has a normal air outlet mode and a windless mode.

[0107] Further, when the switch door 7 is located at a position to open the air outlet 221, at least a portion of the switch door 7 is disposed opposite to the second air inlet 212, and a plurality of ventilation holes 71 are formed on the portion of the switch door 7 opposite to the second air inlet 212.

[0108] For example, when the air-conditioning indoor unit 20 is in the off state, the switch door 7 can close the air outlet 221; when the air-conditioning indoor unit 20 is in the normal air outlet mode, the switch door 7 can open the air outlet 221, and the external air can enter the casing 2 from the first air inlet 211 and the second air inlet 212, and be discharged to the room from the air outlet 221 after heat exchange with the heat exchanger assembly 3; when the air-conditioning indoor unit 20 is in the windless mode, the switch door 7 can close the air outlet 221, and the external air can enter the casing 2 from the first air inlet 211 and the second air inlet 212, and be discharged to the room from the multiple ventilation holes 71 on the switch door 7 after heat exchange with the heat exchanger assembly 3. The air discharged from the air outlet 221 can be dispersed through the multiple ventilation holes 71 on the switch door 7, thereby achieving an air outlet effect without strong wind on the front of the air-conditioning indoor unit 20, and the air outlet is softer, avoiding direct blowing on the user, thereby improving the user's comfort.

When the switch door 7 is located at a position to close the air outlet 221 and the ventilation grille 15 is located at a position to close the vent 121, the front surface of the switch door 7 is flush with the front surface of the ventilation grille 15. After the air conditioner indoor unit 20 is installed in the cabinet 10, the exposed part of the air conditioner indoor unit 20 can be reduced, so that the air conditioner indoor unit 20 is more coordinated with the cabinet 10 and the surrounding environment. Among them, the front surface of the switch door 7 is flush with the front surface of the ventilation grille 15, which also makes the cabinet 10 look neat and beautiful as a whole.

The first bracket 214 and the second bracket 215 are also respectively provided with overflow ports 2141, and the bottom of the second bracket 215 is also provided with a water receiving tray 8. During the operation of the air-conditioning indoor unit 20, the water vapor in the air inside the air-conditioning indoor unit 20 will condense into condensed water near the heat exchanger assembly 3. The condensed water gathered on the first bracket 214 can flow downward to the heat exchanger assembly 3 through the overflow port 2141 on the first bracket 214. The condensed water will flow downward along the heat exchanger assembly 3 to the second bracket 215. The condensed water on the rear shell 21 can flow downward along the rear shell 21 to the second bracket 215. The condensed water gathered on the second bracket 215 flows from the overflow port 2141 of the second bracket 215 to the water receiving tray 8, and is finally discharged from the air-conditioning indoor unit 20 through the drain pipe connected to the water receiving tray 8, and can be discharged to the outdoors.
