[0046] 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 intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0047] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0048] The air conditioner indoor unit 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0049] like Figure 1 and Figure 5 As shown, the air-conditioning indoor unit 100 according to the embodiment of the present invention includes: a housing 10 , a heat exchanger 2 and a fan 3 .

[0050] Specifically, Figure 5 As shown, a first air inlet air flow channel 11 and a second air inlet air flow channel 12 are defined in the shell 10, and a top air inlet 131 connected to the first air inlet air flow channel 11 and the second air inlet air flow channel 12 is provided on the shell 10, the second air inlet air flow channel 12 is located on the front side of the first air inlet air flow channel 11, and a front air inlet 132 connected to the first air inlet air flow channel 11 is provided at the lower end of the second air inlet air flow channel 12.

[0051] It can be understood that the airflow entering the housing 10 from the top air inlet 131 can be diverted to the first air inlet airflow channel 11 and the second air inlet airflow channel 12, wherein the airflow diverted to the second air inlet airflow channel 12 can flow along the second air inlet airflow channel 12 and merge into the first air inlet airflow channel 11 through the front air inlet 132 at the lower end of the second air inlet airflow channel 12. Thus, a single airflow at the inlet position can be dispersed into two streams, and then merged into the first air inlet airflow channel 11 through the top air inlet 131 and the front air inlet 132 at two different positions.

[0052] like Figure 2 and Figure 5 As shown, an outlet air flow channel 15 is defined in the housing 10, and the outlet air flow channel 15 is communicated with the first inlet air flow channel 11, and an air outlet 14 is provided on the housing 10 to communicate with the outlet air flow channel 15. It can be understood that the airflow in the first inlet air flow channel 11 can be blown to the indoor space through the air outlet 14 of the outlet air flow channel 15, and at the same time, the airflow in the second inlet air flow channel 12, after merging into the first inlet air flow channel 11, can also be blown to the indoor space through the air outlet 14 of the outlet air flow channel 15.

[0053] For example, in one example of the present invention, a rotatable inner air guide plate 8 is provided in the outlet air flow channel 15. Thus, by providing the inner air guide plate 8 in the outlet air flow channel 15, the outlet air direction can be changed and adjusted by rotating the inner air guide plate 8.

[0054] Optionally, a rotatable louver may be provided in the air outlet passage 15 , and the louver may guide the air to the left and right. The louver may be provided upstream of the inner air guide plate 8 in the air flow direction.

[0055] like Figure 5 and Figure 6 As shown, the heat exchanger 2 is arranged in the first air inlet air flow channel 11, part of the heat exchanger 2 is opposite to the top air inlet 131, and part of the heat exchanger 2 is opposite to the front air inlet 132. It can be understood that the airflow for heat exchange with the heat exchanger 2 is respectively through the top air inlet 131 and the front air inlet 132 and then contacts the heat exchanger 2 for heat exchange, so that heat exchange can be performed with the heat exchanger 2 in two directions and two positions, thereby improving the heat exchange efficiency of the heat exchanger 2, increasing the cooling and heating capacity of the heat exchanger 2, and further improving the working efficiency of the air conditioner indoor unit 100.

[0056] like Figure 5 and Figure 6 As shown, the fan 3 is arranged in the first air inlet air flow channel 11 to drive the air flow to flow from the top air inlet 131 to the air outlet 14. The fan 3 can realize the forced flow of the air flow, so that the air flow has the power to move from the top air inlet 131 toward the air outlet 14. Specifically, driven by the fan 3, the air flow can enter the first air inlet air flow channel 11 and the second air inlet air flow channel 12 from the top air inlet 131, wherein the air flow directly entering the first air inlet air flow channel 11 can directly exchange heat with the top surface of the heat exchanger 2, and the air flow diverted to the second air inlet air flow channel 12 can flow along the second air inlet air flow channel 12, and merge into the first air inlet air flow channel 11 through the front air inlet 132 at the lower end of the second air inlet air flow channel 12, and then exchange heat with the front of the heat exchanger 2, and finally be transported to the indoor space from the air outlet 14.

[0057] In some embodiments of the present invention, Figure 2 and Figure 5 As shown, the shell 10 includes: a chassis, a face frame 1 and a panel 7, the face frame 1 is connected to the chassis, the face frame 1 has a top air inlet 131, a front air inlet 132 and an air outlet 14, the face frame 1 and the chassis define a first air inlet airflow channel 11, the panel 7 is connected to the face frame 1, and the panel 7 and the face frame 1 define at least a portion of a second air inlet airflow channel 12.

[0058] For example, in one example of the present invention, the face frame 1 is connected to the chassis, the face frame 1 has a top air inlet 131, a front air inlet 132 and an air outlet 14, the face frame 1 and the chassis define a first air inlet airflow channel 11, and the top air inlet 131, the front air inlet 132 and the air outlet 14 are all connected to the first air inlet airflow channel 11. The panel 7 is connected to the face frame 1, and the panel 7 is located on the side of the face frame 1 away from the chassis, the panel 7 and the face frame 1 define at least part of the second air inlet airflow channel 12, the second air inlet airflow channel 12 is separated from the first air inlet airflow channel 11, one end of the second air inlet airflow channel 12 is connected to the top air inlet 131, and the other end of the second air inlet airflow channel 12 is connected to the front air inlet 132.

[0059] Among them, a second air inlet air flow channel 12 is separated between the panel 7 and the face frame 1. When the air-conditioning indoor unit 100 is in the cooling mode, it can prevent the cold air in the face frame 1 after heat exchange with the heat exchanger 2 from contacting the panel 7, causing a large temperature difference between the inner and outer surfaces of the panel 7, thereby reducing or avoiding condensation on the outer surface of the panel 7.

[0060] According to the air-conditioning indoor unit 100 of the embodiment of the present invention, by setting the top air inlet 131 and the front air inlet 132, the air flow can enter the shell 10 through the top air inlet 131 and the front air inlet 132, so that heat can be exchanged with the heat exchanger 2 in two directions, thereby improving the heat exchange efficiency of the heat exchanger 2, increasing the cooling capacity of the heat exchanger 2, and then improving the working efficiency of the air-conditioning indoor unit 100.

[0061] According to some embodiments of the present invention, Figure 5 and Figure 7 As shown, the air conditioner indoor unit 100 further includes a partition 4, which is disposed at the front air inlet 132 to block the front air inlet 132, and a plurality of ventilation holes 41 are disposed on the partition 4. It is understandable that the airflow in the second air inlet air flow channel 12 can enter the first air inlet air flow channel 11 through the ventilation holes 41.

[0062] In some embodiments of the present invention, Figure 5 As shown, the portion of the heat exchanger 2 that is opposite to the partition 4 matches the outer contour of the partition 4. Thus, the heat exchange area between the airflow and the heat exchanger 2 can be increased, thereby further improving the heat exchange efficiency and further improving the working efficiency of the air conditioner indoor unit 100.

[0063] In some embodiments of the present invention, Figure 5As shown, the distance between the partition 4 and the heat exchanger 2 is not less than 5 mm. This ensures that there is a large space between the partition 4 and the heat exchanger 2, so that when the airflow entering the housing 10 from the top air inlet 131 flows to the heat exchanger 2, when the airflow flows into the space between the partition 4 and the heat exchanger 2, the flow rate of the airflow entering the space between the partition 4 and the heat exchanger 2 can be increased, and the heat exchange efficiency of the relative parts of the heat exchanger 2 and the partition 4 can be improved, thereby improving the working efficiency of the whole machine, and reducing the noise generated when the airflow flows into the space between the partition 4 and the heat exchanger 2.

[0064] In some embodiments of the present invention, Figure 7 and Figure 8 As shown, the partition 4 and the shell 10 are an integrally formed part. Therefore, the structure of the integral part can not only ensure the structural and performance stability of the partition 4 and the shell 10, but also facilitate molding and simple manufacturing, and eliminate unnecessary assembly parts and connection processes, greatly improving the assembly efficiency of the partition 4 and the shell 10, and ensuring the connection reliability of the partition 4 and the shell 10. Furthermore, the overall strength and stability of the integrally formed structure are higher, the assembly is more convenient, and the service life is longer. For example, in one example of the present invention, the partition 4 and the face frame 1 of the shell 10 are an integrally formed part.

[0065] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the plurality of ventilation holes 41 are distributed in multiple rows and columns. Thus, the smoothness and uniformity of the airflow through the partition plate 4 can be improved, so that the heat exchange efficiency between the airflow and the heat exchanger 2 is higher. At the same time, the resistance of the airflow flow can be reduced, thereby reducing the power loss of the airflow flow.

[0066] In some embodiments of the present invention, the cross section of the ventilation hole 41 is formed into a circle, an ellipse or a polygon. Thus, the shape of the cross section of the ventilation hole 41 can be selected according to the model, size and application environment of the air conditioner indoor unit 100, so as to improve the versatility of the air conditioner indoor unit 100 and better meet the needs of users. Of course, the present invention is not limited to this, and the shape of the cross section of the ventilation hole 41 can also be an oblong, such as a runway shape.

[0067] According to some embodiments of the present invention, Figure 2 and Fig.10As shown, the air outlet 14 includes a first sub-air outlet 141 located at the front side of the housing 10, and the air conditioner indoor unit 100 also includes: a switch door assembly 5, the switch door assembly 5 is arranged on the housing 10 to be movable up and down between a first position and a second position, and when the switch door assembly 5 is located at the first position, the switch door assembly 5 opens the first sub-air outlet 141. It can be understood that when the switch door assembly 5 is located at the first position, the air conditioner indoor unit 100 discharges air from the first sub-air outlet 141, and the air conditioner indoor unit 100 is in a normal air outlet mode. At this time, the air conditioner indoor unit 100 can be in a cooling mode or a heating mode, and rapid cooling or heating can be achieved.

[0068] When the switch door assembly 5 is located at the second position, the switch door assembly 5 closes the first sub-air outlet 141. It can be understood that when the switch door assembly 5 is located at the second position, the switch door assembly 5 can separate the internal space of the housing 10 from the indoor space, thereby preventing indoor dust or debris from entering the housing 10 through the first sub-air outlet 141, thereby ensuring the reliability of the air conditioner indoor unit 100.

[0069] For example, in one example of the present invention, a first sub-air outlet 141 is formed at the front of the face frame 1, and the first sub-air outlet 141 runs through the bottom of the face frame 1. It can be understood that since the first sub-air outlet 141 is formed at the front of the face frame 1 and the first sub-air outlet 141 runs through the bottom of the face frame 1, the air conditioner indoor unit 100 can discharge air forward and downward at the same time, realize multi-angle air discharge, and increase the air discharge range and air discharge volume.

[0070] For example, in one example of the present invention, a rotatable inner air guide plate 8 is provided in the air outlet air flow channel 15 (see Figure 5 ), the switch door assembly 5 is in the first position and the air conditioner indoor unit 100 is in the cooling mode, the inner air guide plate 8 can be rotated to guide more airflow obliquely upward, for example, the angle between the inner air guide plate 8 and the horizontal plane is in the range of 0-45°; the switch door assembly 5 is in the first position and the air conditioner indoor unit 100 is in the heating mode, the inner air guide plate 8 can be rotated to guide more airflow obliquely downward, for example, the angle between the inner air guide plate 8 and the horizontal plane is in the range of 45-90°. When the switch door assembly 5 is in the second position, the inner air guide plate 8 can be rotated to extend roughly in the up-down direction, so that the inner air guide plate 8 can guide the airflow to the bottom of the first sub-air outlet 141, reduce the amount of airflow blown forward, and further improve the windless effect of the air outlet.

[0071] In some embodiments of the present invention, Figure 3 and Fig.10As shown, the switch door assembly 5 includes a first connection part 51 and a second connection part 52 connected up and down. When the switch door assembly 5 is located in the second position, the second connection part 52 is opposite to the first sub-air outlet 141, and the second connection part 52 is formed with a plurality of air dispersion holes 521. The first connection part 51 is located above the second connection part 52.

[0072] It can be understood that the air-conditioning indoor unit 100 can discharge air through the first sub-air outlet 141, and disperse the airflow through the multiple air dispersion holes 521 on the second connecting part 52, so that the air outlet is soft and a windless air outlet mode is achieved. At this time, the air-conditioning indoor unit 100 can be in the cooling mode, reducing or avoiding the discomfort caused by cold air blowing directly on the human body, and at the same time ensuring a large air outlet volume to ensure the cooling capacity in the windless mode.

[0073] Optionally, the first connecting portion 51 may be a solid structure, thereby improving the overall structural strength of the door assembly 5 .

[0074] Optionally, a decorative hole may be provided on the first connection part 51. Thus, the first connection part 51 and the second connection part 52 may be formed as a whole in appearance, and materials may be saved. The decorative hole may not penetrate the first connection part 51, or may penetrate the first connection part 51.

[0075] In some embodiments of the present invention, Figure 5 As shown, when the switch door assembly 5 is in the first position, the first connection portion 51 is located in the housing 10 and in the second air inlet air flow channel 12. For example, in one example of the present invention, a panel 7 is provided at the upper end of the face frame 1 and the panel 7 is located at the front side of the face frame 1, and a receiving cavity is defined between the panel 7 and the face frame 1. When the switch door assembly 5 is in the first position, the first connection portion 51 is located in the receiving cavity.

[0076] Thus, when the switch door assembly 5 moves upward to the second position, the first connection portion 51 moves upward and enters through the bottom of the receiving cavity and is received in the receiving cavity, which facilitates the storage and hiding of the first connection portion 51; when the switch door assembly 5 moves downward to the first position, the first connection portion 51 moves downward to the outside of the receiving cavity and is located below the receiving cavity. During the movement of the switch door assembly 5, the receiving cavity can also play a guiding role, making the up and down movement of the switch door assembly 5 more stable and reliable. In addition, the appearance of the air conditioner indoor unit 100 is more beautiful.

[0077] For example, in one embodiment of the present invention, Figure 5 and Figure 6As shown, the air conditioner indoor unit 100 further includes a limit plate 42, one end of which is connected to one end of the partition 4, the partition 4 extends in the up-down direction, the limit plate 42 extends in the front-back direction, the limit plate 42 is arranged on the top of the partition 4, the limit plate 42 is connected to the face frame 1, the limit plate 42 is located at the bottom of the receiving cavity, and a receiving passage suitable for the first connecting part 51 to pass through is defined between the front end surface of the limit plate 42 and the panel 7. It can be understood that the receiving passage suitable for the first connecting part 51 to pass through is defined between the front end surface of the limit plate 42 and the panel 7, so as to facilitate the up-and-down movement of the switch door assembly 5, thereby facilitating the up-and-down movement of the first connecting part 51 to be stored or removed from the receiving cavity. Among them, the size of the receiving passage is slightly larger than the thickness of the first connecting part 51.

[0078] It should be noted that the limiting plate 42 is also provided with a ventilation hole 41 .

[0079] In some embodiments of the present invention, Fig.10 and Fig.11 As shown, the switch door assembly 5 includes a diffuser module 6 with a wind dispersing function, and the diffuser module 6 is arranged on the second connecting portion 52. The diffuser module 6 includes: a mounting plate 61 and a diffuser mechanism. A plurality of first air outlet holes 611 arranged in the left-right direction are formed on the mounting plate 61, and the diffuser mechanism is arranged at the first air outlet hole 611. The diffuser mechanism includes a guide vane assembly 62, and each first air outlet hole 611 is provided with a guide vane assembly 62. The guide vane assembly 62 includes a stationary vane 621 and a rotatable moving vane 622. The stationary vane 621 and the moving vane 622 are arranged along the axial direction of the first air outlet hole 611. Along the airflow direction, the moving vane 622 is arranged downstream or upstream of the stationary vane 621, and the moving vane 622 is arranged coaxially with the stationary vane 621.

[0080] Therefore, when the switch door assembly 5 is in the second position, the wind blown out from the first sub-air outlet 141 can be swirled and dispersed through the dispersion module 6, making the airflow more dispersed and having a certain rotation direction, further enhancing the windless effect.

[0081] For example, in one example of the present application, the moving blades 622 are arranged downstream of the stationary blades 621. When the airflow flows through the diffuser module 6, the airflow is guided, rectified and dispersed by the stationary blades 621 in sequence, and then flows through the moving blades 622. The moving blades 622 can have a certain rotation direction, so that the airflow has a certain rotation direction after flowing through the moving blades 622. Finally, the airflow is further dispersed through the air dispersion holes 521 on the second connecting part 52, so that the air outlet is softer and closer to natural wind.

[0082] The relative position of the blades of the moving blades 622 and the blades of the stationary blades 621 can be changed by controlling the moving blades 622 to rotate, so that the ventilation area of ​​the first air outlet 611 can be adjusted, and thus the air volume and air speed can be adjusted. When the air conditioner indoor unit 100 is working and the switch door assembly 5 is in the second position, the moving blades 622 can be controlled to rotate to a certain angle and then stop rotating, or the moving blades 622 can be controlled to rotate all the time.

[0083] According to some embodiments of the present invention, Figure 1 and Figure 4 As shown, the air outlet 14 (refer to Figure 5 ) also includes a second sub-air outlet 142, and at least one of the left and right sides of the housing 10 is provided with a second sub-air outlet 142. In other words, the left side of the housing 10 is provided with a second sub-air outlet 142; or, the right side of the housing 10 is provided with a second sub-air outlet 142; or, both the left and right sides of the housing 10 are provided with a second sub-air outlet 142. In this way, more angles of air discharge and a larger range of air discharge can be achieved, the air discharge volume is increased, and the efficiency is improved.

[0084] For example, a second sub-air outlet 142 is formed on the left side of the face frame 1, and when the air-conditioning indoor unit 100 discharges air, the air can be discharged toward the front, downward, and left, forming a 3D air outlet; a second sub-air outlet 142 is formed on the right side of the face frame 1, and when the air-conditioning indoor unit 100 discharges air, the air can be discharged toward the front, downward, and right, forming a 3D air outlet; second sub-air outlets 142 are formed on both the left side of the face frame 1 and the right side of the face frame 1, and when the air-conditioning indoor unit 100 discharges air, the air can be discharged toward the front, downward, left, and right, forming a 4D air outlet.

[0085] Specifically, the air-conditioning indoor unit 100 includes a switch door assembly 5, and the switch door assembly 5 includes a first connection part 51 and a second connection part 52 connected up and down. When the switch door assembly 5 is located in the second position, the second connection part 52 is opposite to the first sub-air outlet 141, and the second connection part 52 is formed with a plurality of wind dispersion holes 521. The first connection part 51 is located above the second connection part 52. When the switch door assembly 5 is in the second position, the air-conditioning indoor unit 100 is in a windless mode. Since at least one second sub-air outlet 142 is added on the left and right sides, and since the air outlet on the left and right sides will not blow directly onto the human body, the cooling capacity in the windless mode can be further increased while ensuring the realization of the windless mode.

[0086] For example, in Figure 4In the example, a second sub-air outlet 142 is formed on the left end surface of the face frame 1 and the right end surface of the face frame 1, and end plates are provided on the left and right sides of the face frame 1. The end plates can be in a grille shape, and the second sub-air outlet 142 can exhaust air from the gaps in the end plates. Therefore, when the air-conditioning indoor unit 100 is in the windless mode, the left and right air outlets can be softer, thereby improving the overall windless effect of the air-conditioning indoor unit 100.

[0087] In one example of the present invention, referring to Fig.10 and Fig.11 The driving mechanism 9 for driving the door opening and closing assembly 5 to move up and down includes: a motor 91, a gear and a rack 92. The motor 91 is arranged on the chassis of the air conditioner indoor unit 100, the chassis is connected to the face frame 1, the gear is connected to the output shaft of the motor 91, the rack 92 is arranged on the door opening and closing assembly 5 and extends in the up and down direction, and the rack 92 is suitable for meshing with the gear. Therefore, the gear is driven to rotate by the motor 91, thereby driving the rack 92 to move up and down, and further driving the door opening and closing assembly 5 to move up and down.

[0088] Optionally, the rack 92 is disposed on the movable panel of the door opening and closing assembly 5, and the rack 92 is detachably connected to the movable panel, thereby facilitating the disassembly and replacement of the rack 92. Alternatively, the rack 92 is integrally formed with the movable panel. Thus, the assembly process of the air conditioner indoor unit 100 can be simplified, and the connection strength between the rack 92 and the movable panel can be improved.
