Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an indoor air conditioning unit. Background Technology

[0002] In related technologies, for ceiling-mounted air conditioner indoor units, the air conditioner indoor unit typically includes an air conditioning unit and an air outlet module. The air outlet module is connected to the air conditioning unit via a ventilation hose. The air inside the air conditioning unit can be discharged into the room in sequence through the ventilation hose and the air outlet module to change the indoor temperature.

[0003] However, on the one hand, due to the relatively long length of the ventilation hoses (i.e., the longer air duct), and the fact that the inner surface of the ventilation hoses is usually uneven, ventilation hoses not only result in significant airflow loss but also lead to a more dispersed distribution between the air conditioning unit and the air outlet modules, resulting in a larger space occupied by the indoor unit; in addition, the longer ventilation hoses also lead to higher costs. On the other hand, because ventilation hoses are easily deformed, their resistance to wind resistance is relatively weak. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the related technologies, this application provides an air conditioner indoor unit to solve the problems of large air volume loss, large space occupation, high cost and weak wind resistance of the air conditioner indoor unit in the related technologies.

[0005] To address the aforementioned technical problems, in a first aspect, this application provides an air conditioner indoor unit, which includes:

[0006] Air conditioner main body, the air conditioner main body includes:

[0007] The main body housing has a first air outlet channel inside and an air inlet on the main body housing. The air inlet is located at the front of the indoor unit of the air conditioner and is connected to the first air outlet channel.

[0008] A cross-flow fan, which is disposed inside the main body housing, is used to draw air from outside the main body housing into the main body housing through the air inlet;

[0009] A heat exchanger is disposed inside the main body housing for exchanging heat with the air inside the main body housing;

[0010] Air outlet module, the air outlet module comprising:

[0011] The module housing is directly connected to the main body housing. A second air outlet channel is provided inside the module housing, which is connected to the first air outlet channel. An air outlet is provided on the module housing, which is located at the bottom of the indoor unit of the air conditioner and is connected to the second air outlet channel. The cross-flow fan is also used to discharge the heat-exchanged air through the first air outlet channel, the second air outlet channel and the air outlet to the main body housing.

[0012] With this configuration, since the main body shell and the module shell are directly connected, and since the main body shell has a first air outlet channel and the module shell has a second air outlet channel, the air outlet module can be connected to the air conditioner body through the connection between the module shell and the main body shell. The air outlet module does not need to be connected to the air conditioner body through a ventilation hose. After the main body shell and the module shell are connected, the first air outlet channel and the second air outlet channel can be directly connected, and the air inlet can be connected to the air outlet through the first air outlet channel and the second air outlet channel.

[0013] Based on the above, on the one hand, since the air outlet module no longer needs to be connected to the air conditioner unit via a ventilation hose, it helps to shorten the air duct. Simultaneously, the inner walls of the first and second air outlet channels enclosed by the casing are relatively smooth, without the unevenness of the inner surface of the ventilation hose, resulting in less resistance to airflow. Therefore, this not only helps reduce airflow loss during transmission but also allows for a more compact arrangement between the air conditioner unit and the air outlet module, thus reducing the space occupied by the indoor unit. Furthermore, eliminating the need for a ventilation hose also helps reduce costs.

[0014] On the other hand, since the main body shell is directly connected to the module shell, and since the shell forms the first and second air outlet channels, the air outlet channels are relatively fixed and not easily deformed, and can withstand greater wind pressure, which is beneficial to enhancing wind resistance.

[0015] Optionally, the module housing is detachably connected to the main housing.

[0016] This design allows for a detachable connection between the air outlet module and the air conditioner unit. This firstly allows the air outlet module and the air conditioner unit to be transported separately. Compared to the entire indoor air conditioner unit, the air outlet module and the air conditioner unit each occupy relatively less space and have less weight, which facilitates the transportation of the indoor air conditioner unit.

[0017] Secondly, during installation, installers can first install the main air conditioner unit in a suitable location, and then install the air outlet module. This allows for better adaptation to different installation scenarios and facilitates the installation of the indoor unit. Furthermore, for indoor units installed later, the sequential installation of the main air conditioner unit and the air outlet module helps prevent damage to the ceiling.

[0018] Finally, when the air conditioner unit or air outlet module malfunctions, the detachable connection makes it easy for maintenance personnel to separate the air conditioner unit from the air outlet module, which facilitates the maintenance and repair of the air conditioner unit or air outlet module.

[0019] Optionally, the module housing is snap-fitted into the main body housing.

[0020] This design simplifies the connection between the module housing and the main body housing, making the connection between them easier and facilitating a quick connection. The snap-fit ​​mechanism provides reliable connection strength, ensuring a tight fit between the module housing and the main body housing.

[0021] Optionally, the main housing is provided with a snap-fit ​​hole, and a snap-fit ​​structure is provided in the snap-fit ​​hole;

[0022] The module housing is provided with a buckle, which is inserted into the buckle hole and engages with the buckling structure.

[0023] This design not only simplifies the interlocking structure between the module housing and the main body housing to a certain extent, but also guides the module housing and the main body housing to align accurately during connection by inserting the buckle into the buckle hole. This helps ensure the positional accuracy of the module housing and the main body housing during connection, ensuring seamless connection between the first and second air outlet channels, allowing air to flow smoothly within the air outlet channels.

[0024] Optionally, the snap-fit ​​structure is an elastic claw disposed on the inner wall of the snap-fit ​​hole.

[0025] With this design, when the buckle is inserted into the locking hole and engages with the elastic claw, the elastic claw can block the buckle. This blocking effect can effectively prevent the buckle from coming out of the locking hole when subjected to external force, thus helping to ensure the stability of the connection. At the same time, the elastic claw can also prevent the buckle from getting stuck in the locking hole through its elastic deformation, ensuring that the buckle can be easily pulled out of the locking hole.

[0026] Optionally, the buckle has a snap-fit ​​surface that snaps into the snap-fit ​​structure, and multiple grooves are spaced apart on at least one surface of the buckle other than the snap-fit ​​surface.

[0027] This design serves two purposes. First, the multiple grooves help reduce the weight of the buckle, which in turn reduces the weight of the module housing, facilitating a lightweight design. Second, reinforcing ribs can be formed between any two adjacent grooves, enhancing the structural strength of the buckle. This allows the buckle to more effectively resist bending deformation, ensuring a tight fit between the buckle and the snap-fit ​​structure, and maintaining a stable connection between the main housing and the module housing.

[0028] Optionally, the inner wall of the card hole includes:

[0029] Inner wall section of the locator;

[0030] The guide bevel section is arranged opposite to the inner wall section of the card hole in a direction perpendicular to the extension direction of the card hole, and the guide bevel section and the inner wall section of the card hole form an insertion port for the buckle to be inserted into the card hole;

[0031] In the extending direction of the card hole, the guide bevel section is inclined and gradually approaches the inner wall section of the card hole from the insertion port to the inner side of the card hole.

[0032] With this design, during the insertion of the buckle into the card hole, after the buckle comes into contact with the guide slope section, it will naturally slide into the card hole along the guide slope section. In other words, the guide slope section can guide the buckle to be inserted into the card hole, making it easier for the buckle to be inserted into the card hole. This is more conducive to facilitating the engagement between the buckle and the card hole, and helps to improve the connection efficiency between the main body shell and the module shell.

[0033] Optionally, the module housing includes:

[0034] The air duct housing is used to be installed in the mounting opening formed by multiple ceiling panels, and the second air outlet channel is installed in the air duct housing.

[0035] An air outlet panel is connected to the air duct housing. An air outlet is disposed on the air outlet panel. The air outlet panel is used to be disposed below multiple ceiling panels. The outer edge of the air outlet panel is projected onto the multiple ceiling panels in the vertical direction as a panel projection. The mounting port is disposed on the inner side of the panel projection.

[0036] This design offers several advantages. Firstly, since the air outlet panel is positioned below multiple ceiling panels, it doesn't need to be mounted on the ceiling joists via the ceiling panels. This prevents the air outlet panel from applying pressure to the ceiling joists, resulting in more even stress distribution and stability. Secondly, it provides greater flexibility in choosing the installation location for the indoor air conditioning unit, especially for installations with ceiling joists of varying spacing.

[0037] On the other hand, since the installation port is located inside the panel projection, the gap between the air duct housing and multiple ceiling panels can be covered by the air outlet panel, which helps to improve the aesthetics of the installation.

[0038] Optionally, the air outlet module further includes:

[0039] An air guide plate is rotatably disposed on the module housing and disposed at the air outlet. The air guide plate is used to guide the air flowing out of the air outlet.

[0040] A rotation drive component is disposed in the module housing and is used to drive the air guide plate to rotate.

[0041] This configuration allows the air guide plate to be rotated by rotating the drive component, which can adjust the angle of the air guide plate and achieve multi-angle air outlet. This ensures that the air blown out by the indoor unit of the air conditioner can be accurately directed to the required area, thereby improving the comfort of using the indoor unit of the air conditioner.

[0042] Optionally, the height of the indoor unit of the air conditioner is h, where h ≥ 200 mm and h ≤ 292 mm.

[0043] This design allows the height of the indoor air conditioner unit to fit into most kitchen ceiling spaces, thus improving the applicability of the indoor air conditioner unit installation. Attached Figure Description

[0064] As described in the background section of this application, in related technologies, for ceiling-mounted air conditioning indoor units, the air conditioning indoor unit typically includes an air conditioning unit and an air outlet module. The air outlet module is connected to the air conditioning unit via a ventilation hose, and the air inside the air conditioning unit can be discharged into the room in sequence through the ventilation hose and the air outlet module to change the indoor temperature.

[0065] However, on the one hand, due to the relatively long length of the ventilation hoses (i.e., the longer air duct), and the fact that the inner surface of the ventilation hoses is usually uneven, ventilation hoses not only result in significant airflow loss but also lead to a more dispersed distribution between the air conditioning unit and the air outlet modules, resulting in a larger space occupied by the indoor unit; in addition, the longer ventilation hoses also lead to higher costs. On the other hand, because ventilation hoses are easily deformed, their resistance to wind resistance is relatively weak.

[0066] In view of the above-mentioned problems, this application provides an air conditioner indoor unit to solve the problems of large air volume loss, large space occupation, high cost and weak wind resistance of air conditioner indoor units in related technologies.

[0067] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings:

[0068] In some embodiments, such as Figure 1 As shown, the indoor unit of the air conditioner includes the air conditioner body 1, such as... Figure 2 and Figure 3As shown, the air conditioner body 1 includes a main body shell 11, a first air outlet channel 12 is provided inside the main body shell 11, and an air inlet 111 is provided on the main body shell 11. The air inlet 111 is located at the front of the indoor unit of the air conditioner and is connected to the first air outlet channel 12.

[0069] With this configuration, the air inlet 111 is the entrance for air to enter, and the first air outlet duct 12 is the duct for air circulation. This helps to ensure that air can flow orderly inside the air conditioning unit 1, establishing a basic path for air circulation in the indoor unit of the air conditioner.

[0070] In some embodiments, the air conditioner body 1 further includes a cross-flow fan disposed within the body housing 11, which draws air from outside the body housing 11 into the body housing 11 through the air inlet 111. This configuration allows the cross-flow fan to enable faster and more stable airflow into the body housing 11, thus facilitating a stable and continuous supply of air to be processed into the body housing 11 and accelerating the overall indoor air circulation.

[0071] In some embodiments, the air conditioner body 1 further includes a heat exchanger disposed within the body housing 11 for exchanging heat with the air within the body housing 11. This arrangement allows the heat exchanger to directly exchange heat with the air, enabling rapid changes in air temperature. This allows the indoor unit of the air conditioner to quickly begin adjusting the indoor air temperature upon receiving a user-set temperature adjustment command. Consequently, the indoor temperature can be raised in a short time, reducing the time users spend waiting for the room to warm up. Furthermore, this efficient heat exchange process helps to meet temperature regulation needs while avoiding excessive energy consumption.

[0072] In some embodiments, such as Figure 1 As shown, the indoor unit of the air conditioner also includes an air outlet module 2, such as Figure 4 , Figure 5 and Figure 9 As shown, the air outlet module 2 includes a module housing 21, which is directly connected to the main housing 11. A second air outlet channel 22 is provided inside the module housing 21, which is connected to the first air outlet channel 12. An air outlet 211 is provided on the module housing 21, which is located at the bottom of the indoor unit of the air conditioner. The air outlet 211 is connected to the second air outlet channel 22. The cross-flow fan also discharges the heat-exchanged air through the first air outlet channel 12, the second air outlet channel 22 and the air outlet 211 to the main housing 11.

[0073] With this configuration, since the main housing 11 is directly connected to the module housing 21, the air outlet module 2 can be connected to the air conditioning unit 1 through the connection between the module housing 21 and the main housing 11, and the air outlet module 2 does not need to be connected to the air conditioning unit 1 through a ventilation hose.

[0074] Based on the above, on the one hand, since the air outlet module 2 no longer needs to be connected to the air conditioner body 1 via a ventilation hose, it helps to shorten the air duct. Simultaneously, the inner walls of the first air outlet channel 12 and the second air outlet channel 22, enclosed by the casing, are relatively flat, without the unevenness of the inner surface of the ventilation hose, resulting in less resistance to airflow. Therefore, this not only helps reduce airflow loss during transmission but also allows for a more compact arrangement between the air conditioner body 1 and the air outlet module 2, thereby reducing the space occupied by the indoor unit. Furthermore, eliminating the need for a ventilation hose also helps reduce costs.

[0075] On the other hand, since the main body shell 11 is directly connected to the module shell 21, and since the shell forms the first air outlet channel 12 and the second air outlet channel 22, the air outlet channels are relatively fixed and not easily deformed, and can withstand greater wind pressure, which is beneficial to enhancing wind resistance.

[0076] In some embodiments, such as Figure 1 As shown, the indoor unit of the air conditioner includes the main air conditioner body 1 and the air outlet module 2. Among them, as... Figure 2 and Figure 3 As shown, the air conditioner main body 1 includes a main housing 11, a cross-flow fan, and a heat exchanger. A first air outlet duct 12 is provided inside the main housing 11, and an air inlet 111 is provided on the main housing 11. The air inlet 111 is located at the front of the indoor unit of the air conditioner and communicates with the first air outlet duct 12. The cross-flow fan is disposed inside the main housing 11 and is used to draw air from outside the main housing 11 into the main housing 11 through the air inlet 111. The heat exchanger is disposed inside the main housing 11 and is used to exchange heat with the air inside the main housing 11.

[0077] like Figure 4 , Figure 5 and Figure 9 As shown, the air outlet module 2 includes a module housing 21, which is directly connected to the main housing 11. A second air outlet channel 22 is provided inside the module housing 21, which is connected to the first air outlet channel 12. An air outlet 211 is provided on the module housing 21, which is located at the bottom of the indoor unit of the air conditioner. The air outlet 211 is connected to the second air outlet channel 22. The cross-flow fan also discharges the heat-exchanged air through the first air outlet channel 12, the second air outlet channel 22 and the air outlet 211 to the main housing 11.

[0078] With this configuration, since the main housing 11 is directly connected to the module housing 21, and since the main housing 11 has a first air outlet channel 12 and the module housing 21 has a second air outlet channel 22, the air outlet module 2 can be connected to the air conditioner body 1 through the connection between the module housing 21 and the main housing 11. The air outlet module 2 does not need to be connected to the air conditioner body 1 through a ventilation hose. After the main housing 11 and the module housing 21 are connected, the first air outlet channel 12 and the second air outlet channel 22 can be directly connected, and the air inlet 111 can be connected to the air outlet 211 through the first air outlet channel 12 and the second air outlet channel 22.

[0079] Based on the above, on the one hand, since the air outlet module 2 no longer needs to be connected to the air conditioner body 1 via a ventilation hose, it helps to shorten the air duct. Simultaneously, the inner walls of the first air outlet channel 12 and the second air outlet channel 22, enclosed by the casing, are relatively flat, without the unevenness of the inner surface of the ventilation hose, resulting in less resistance to airflow. Therefore, this not only helps reduce airflow loss during transmission but also allows for a more compact arrangement between the air conditioner body 1 and the air outlet module 2, thereby reducing the space occupied by the indoor unit. Furthermore, eliminating the need for a ventilation hose also helps reduce costs.

[0080] On the other hand, since the main body shell 11 is directly connected to the module shell 21, and since the shell forms the first air outlet channel 12 and the second air outlet channel 22, the air outlet channels are relatively fixed and not easily deformed, and can withstand greater wind pressure, which is beneficial to enhancing wind resistance.

[0081] In addition, by placing the air inlet 111 at the front of the indoor unit and the air outlet 211 at the bottom of the indoor unit, the indoor unit can achieve front air intake and bottom air exhaust. In this way, not only is there no need to connect the air outlet module 2 and the air conditioner body 1 with a ventilation hose, but also since the air inlet 111 only needs to allow air intake, there is no need to connect the air inlet 111 with the ventilation opening on the ceiling panel. This also helps to reduce the space occupied by the indoor unit and reduce costs.

[0082] In some embodiments, such as Figure 1 As shown, the indoor unit of the air conditioner includes the air conditioner body 1, such as... Figure 2 and Figure 3 As shown, the air conditioner body 1 includes a main housing 11, a first air outlet duct 12 is provided inside the main housing 11, and an air inlet 111 is provided on the main housing 11. The air inlet 111 is located at the front of the indoor unit of the air conditioner and is connected to the first air outlet duct 12. Figure 2 and Figure 3As shown, the main body shell 11 has a first splicing part 112, and a first connecting port 1121 is provided on the first splicing part 112, which is connected to the first air outlet channel 12.

[0083] With this configuration, the air inlet 111 is the entrance for air to enter, the first air outlet 12 is the duct for air circulation, and the first connecting port 1121 is the outlet for air to exit the first air outlet 12. This helps ensure that air can flow orderly inside the air conditioning unit 1, establishing a basic path for air circulation in the indoor unit of the air conditioner.

[0084] In some embodiments, such as Figure 1 As shown, the indoor unit of the air conditioner also includes an air outlet module 2, such as Figure 4 and Figure 5 As shown, the air outlet module 2 includes a module housing 21, a second air outlet channel 22 is provided inside the module housing 21, the module housing 21 has a second splicing part 212, a second connecting port 2121 is provided on the second splicing part 212, the second connecting port 2121 is connected to the second air outlet channel 22, and the second splicing part 212 is spliced ​​and connected to the first splicing part 112 so that the second connecting port 2121 is connected to the first connecting port 1121.

[0085] like Figure 9 As shown, an air outlet 211 is provided on the module housing 21. The air outlet 211 is located at the bottom of the indoor unit of the air conditioner. The air outlet 211 is connected to the second air outlet channel 22. The cross-flow fan also discharges the heat-exchanged air from the main housing 11 through the first air outlet channel 12, the second air outlet channel 22 and the air outlet 211.

[0086] With this configuration, since the second splicing part 212 is spliced ​​and connected to the first splicing part 112, the main body shell 11 can be directly connected to the module shell 21 through the splicing and connection of the second splicing part 212 and the first splicing part 112. Thus, the air conditioner main body 1 can be directly connected to the air outlet module 2, so that the air outlet module 2 no longer needs to be connected to the air conditioner main body 1 through a ventilation hose.

[0087] Based on the above, on the one hand, since the air outlet module 2 no longer needs to be connected to the air conditioner body 1 via a ventilation hose, it helps to shorten the air duct. Simultaneously, the inner walls of the first air outlet channel 12 and the second air outlet channel 22, enclosed by the casing, are relatively flat, without the unevenness of the inner surface of the ventilation hose, resulting in less resistance to airflow. Therefore, this not only helps reduce airflow loss during transmission but also allows for a more compact arrangement between the air conditioner body 1 and the air outlet module 2, thereby reducing the space occupied by the indoor unit. Furthermore, eliminating the need for a ventilation hose also helps reduce costs.

[0088] On the other hand, since the main body shell 11 is directly connected to the module shell 21, and since the shell forms the first air outlet channel 12 and the second air outlet channel 22, the air outlet channels are relatively fixed and not easily deformed, and can withstand greater wind pressure, which is beneficial to enhancing wind resistance.

[0089] In some embodiments, such as Figure 1 As shown, the indoor unit of the air conditioner includes the main air conditioner body 1 and the air outlet module 2. Among them, as... Figure 2 and Figure 3 As shown, the air conditioner body 1 includes a main housing 11, a cross-flow fan, and a heat exchanger. The air conditioner body 1 includes a main housing 11, a first air outlet duct 12 is provided inside the main housing 11, and an air inlet 111 is provided on the main housing 11. The air inlet 111 is located at the front of the indoor unit of the air conditioner and is connected to the first air outlet duct 12. Figure 2 and Figure 3 As shown, the main body shell 11 has a first splicing part 112, and a first connecting port 1121 is provided on the first splicing part 112, which is connected to the first air outlet channel 12.

[0090] A cross-flow fan is installed inside the main housing 11 to draw air from outside the main housing 11 into the main housing 11 through the air inlet 111. A heat exchanger is installed inside the main housing 11 to exchange heat with the air inside the main housing 11.

[0091] like Figure 4 and Figure 5 As shown, the air outlet module 2 includes a module housing 21, a second air outlet channel 22 is provided inside the module housing 21, the module housing 21 has a second splicing part 212, a second connecting port 2121 is provided on the second splicing part 212, the second connecting port 2121 is connected to the second air outlet channel 22, and the second splicing part 212 is spliced ​​and connected to the first splicing part 112 so that the second connecting port 2121 is connected to the first connecting port 1121.

[0092] like Figure 9 As shown, an air outlet 211 is provided on the module housing 21. The air outlet 211 is located at the bottom of the indoor unit of the air conditioner. The air outlet 211 is connected to the second air outlet channel 22. The cross-flow fan also discharges the heat-exchanged air from the main housing 11 through the first air outlet channel 12, the second air outlet channel 22 and the air outlet 211.

[0093] With this configuration, since the main body shell 11 has a first splicing part 112 and the module shell 21 has a second splicing part 212, and since the second splicing part 212 is spliced ​​and connected to the first splicing part 112, the main body shell 11 can be directly connected to the module shell 21 through the splicing connection of the second splicing part 212 and the first splicing part 112. Thus, the air conditioner body 1 can be directly connected to the air outlet module 2. In this way, the air outlet module 2 no longer needs to be connected to the air conditioner body 1 through a ventilation hose. After the second splicing part 212 is spliced ​​and connected to the first splicing part 112, since the second connecting port 2121 is connected to the first connecting port 1121, the first air outlet channel 12 and the second air outlet channel 22 can be directly connected. Thus, the air inlet 111 can be connected to the air outlet 211 through the first air outlet channel 12 and the second air outlet channel 22.

[0094] Based on the above, on the one hand, since the air outlet module 2 no longer needs to be connected to the air conditioner body 1 via a ventilation hose, it helps to shorten the air duct. Simultaneously, the inner walls of the first air outlet channel 12 and the second air outlet channel 22, enclosed by the casing, are relatively flat, without the unevenness of the inner surface of the ventilation hose, resulting in less resistance to airflow. Therefore, this not only helps reduce airflow loss during transmission but also allows for a more compact arrangement between the air conditioner body 1 and the air outlet module 2, thereby reducing the space occupied by the indoor unit. Furthermore, eliminating the need for a ventilation hose also helps reduce costs.

[0095] On the other hand, since the main body shell 11 is directly connected to the module shell 21, and since the shell forms the first air outlet channel 12 and the second air outlet channel 22, the air outlet channels are relatively fixed and not easily deformed, and can withstand greater wind pressure, which is beneficial to enhancing wind resistance.

[0096] In addition, by placing the air inlet 111 at the front of the indoor unit and the air outlet 211 at the bottom of the indoor unit, the indoor unit can achieve front air intake and bottom air exhaust. In this way, not only is there no need to connect the air outlet module 2 and the air conditioner body 1 with a ventilation hose, but also since the air inlet 111 only needs to allow air intake, there is no need to connect the air inlet 111 with the ventilation opening on the ceiling panel. This also helps to reduce the space occupied by the indoor unit and reduce costs.

[0097] In some embodiments, the module housing 21 is detachably connected to the main housing 11.

[0098] This design allows for a detachable connection between the air outlet module 2 and the air conditioner body 1. This firstly allows the air outlet module 2 and the air conditioner body 1 to be transported separately. Compared to the entire indoor air conditioner unit, the air outlet module 2 and the air conditioner body 1 each occupy relatively less space and have a smaller weight, which facilitates the transportation of the indoor air conditioner unit.

[0099] Secondly, during installation, installers can first install the air conditioner unit 1 in a suitable location, and then install the air outlet module 2. This allows for better adaptation to different installation scenarios and facilitates the installation of the indoor unit. Furthermore, for indoor units installed later, the sequential installation of the air conditioner unit 1 and air outlet module 2 helps prevent damage to the ceiling.

[0100] Finally, when the air conditioner unit 1 or the air outlet module 2 malfunctions, the detachable connection method makes it easy for maintenance personnel to separate the air conditioner unit 1 from the air outlet module 2, which in turn facilitates the maintenance and repair of the air conditioner unit 1 or the air outlet module 2.

[0101] In some embodiments, the module housing 21 is snapped into the main housing 11.

[0102] This design simplifies the connection between the module housing 21 and the main housing 11, thereby facilitating the connection between them and enabling a quick and easy connection. The snap-fit ​​mechanism provides reliable connection strength, allowing the module housing 21 and the main housing 11 to fit together tightly.

[0103] In some embodiments, the module housing 21 and the main housing 11 can also be detachably connected by means of bolts, magnetic connection, or other methods. The structural configuration for achieving a detachable connection is quite flexible and can be set according to actual needs.

[0104] In some embodiments, such as Figure 2 , Figure 3 and Figure 6 As shown, the main body shell 11 is provided with a snap hole 113, and a snap-fit ​​structure 114 is provided inside the snap hole 113.

[0105] like Figure 4 and Figure 5 As shown, the module housing 21 is provided with a buckle 213, such as Figure 7 As shown, the buckle 213 is inserted into the buckle hole 113 and engages with the buckle structure 114.

[0106] This design not only simplifies the interlocking structure between the module housing 21 and the main housing 11 to a certain extent, but also guides the module housing 21 and the main housing 11 to be accurately aligned during connection by inserting the buckle 213 into the buckle hole 113. This helps to ensure the positional accuracy of the module housing 21 and the main housing 11 during connection, ensuring that the first air outlet channel 12 and the second air outlet channel 22 can be seamlessly connected, allowing air to flow smoothly in the air outlet channel.

[0107] In some embodiments, the main housing 11 and the module housing 21 can also be engaged through a slot and hook engagement structure or a ball head and socket engagement structure. The structure for achieving the engagement is flexible and can be configured according to actual needs.

[0108] In some embodiments, such as Figure 6 As shown, the snap-fit ​​structure 114 is an elastic snap-fit ​​claw disposed on the inner wall of the snap-fit ​​hole 113.

[0109] With this configuration, when the latch 213 is inserted into the latch hole 113 and engages with the elastic claw, the elastic claw can block the latch 213. This blocking effect can effectively prevent the latch 213 from coming out of the latch hole 113 when subjected to external force, thereby helping to ensure the stability of the connection. At the same time, the elastic claw can also prevent the latch 213 from getting stuck in the latch hole 113 through its elastic deformation, ensuring that the latch 213 can be smoothly pulled out of the latch hole 113.

[0110] In some embodiments, the snap-fit ​​structure 114 is a slot provided on the inner wall of the snap-fit ​​hole 113, and the snap fastener 213 can enter the slot to achieve snap-fit ​​engagement.

[0111] This design allows the slot to provide better positioning, effectively preventing the buckle 213 from coming out when subjected to external forces in various directions, thus ensuring a reliable connection between the module housing 21 and the main housing 11.

[0112] On the other hand, the slot and buckle 213 enable precise positioning. During assembly, the buckle 213 must be aligned with the slot before insertion, which helps ensure the positional accuracy between the module housing 21 and the main housing 11, and ensures the accurate docking of internal structures such as the air outlet channel.

[0113] In some embodiments, such as Figure 8 As shown, the buckle 213 has a snap-fit ​​surface 2131, which snaps into the snap-fit ​​structure 114. At least one surface of the buckle 213 other than the snap-fit ​​surface 2131 is provided with a plurality of grooves 2132 at intervals.

[0114] This design has two advantages. First, the multiple grooves 2132 help reduce the weight of the buckle 213, which in turn helps reduce the weight of the module housing 21, thus facilitating a lightweight design for the module housing 21. Second, reinforcing ribs can be formed between any two adjacent grooves 2132, which enhances the structural strength of the buckle 213. This helps the buckle 213 resist bending deformation more effectively, ensuring a tight fit between the buckle 213 and the snap-fit ​​structure 114, and maintaining a stable connection between the main housing 11 and the module housing 21.

[0115] In some embodiments, such as Figure 6 As shown, the inner wall of the locator 113 includes a locator inner wall section 1131 and a guide slope section 1132, in a direction perpendicular to the extending direction of the locator 113 (e.g., ...). Figure 6 In the X direction, the guide slope section 1132 and the inner wall section 1131 of the card hole are arranged opposite to each other, and the guide slope section 1132 and the inner wall section 1131 of the card hole form an insertion port 1133 for the buckle 213 to be inserted into the card hole 113.

[0116] In the extension direction of the caliper 113 (e.g.) Figure 6 In the Y direction, the guide slope section 1132 is inclined and gradually approaches the inner wall section 1131 of the card hole from the insertion port 1133 to the inner side of the card hole 113.

[0117] With this configuration, during the insertion of the buckle 213 into the card hole 113, after the buckle 213 contacts the guide slope section 1132, it will naturally slide into the card hole 113 along the guide slope section 1132. That is, the guide slope section 1132 can guide the buckle 213 to be inserted into the card hole 113, making it easier for the buckle 213 to be inserted into the card hole 113. This is more conducive to facilitating the engagement between the buckle 213 and the card hole 113, and helps to improve the connection efficiency between the main body housing 11 and the module housing 21.

[0118] In some embodiments, such as Figure 4 As shown, the module housing 21 includes an air duct housing 214 and an air outlet panel 215. The air duct housing 214 is used to be installed in the mounting opening formed by multiple ceiling panels 3, and the second air outlet channel 22 is installed in the air duct housing 214.

[0119] The air outlet panel 215 is connected to the air duct housing 214, such as Figure 9 and Figure 10 As shown, the air outlet 211 is located on the air outlet panel 215, which is used to be installed below multiple ceiling panels 3. The outer edge of the air outlet panel 215 is positioned along the vertical direction (e.g., ...). Figure 10 The projection of the Y-direction of the ceiling panels 3 onto the multiple ceiling panels is the panel projection, and the mounting opening is located on the inside of the panel projection.

[0120] This design offers several advantages. Firstly, since the air outlet panel 215 is positioned below multiple ceiling panels 3, it does not need to be mounted on the ceiling joists via the ceiling panels 3. This prevents the air outlet panel 215 from applying pressure to the ceiling joists, resulting in more even stress distribution and stability across the joists. Secondly, it provides greater flexibility in choosing the installation location for the indoor air conditioning unit, especially for installations with ceiling joists of varying spacing.

[0121] On the other hand, since the mounting port is located inside the panel projection, the gap between the air duct housing 214 and the multiple ceiling panels 3 can be covered by the air outlet panel 215, which helps to improve the aesthetics of the installation appearance.

[0122] In some embodiments, such as Figure 4 and Figure 9 As shown, the air outlet module 2 also includes an air guide plate 23 and a rotation drive component 24. The air guide plate 23 is rotatably disposed on the module housing 21 and is located at the air outlet 211. The air guide plate 23 is used to guide the air flowing out of the air outlet 211. The rotation drive component 24 is disposed on the module housing 21 and is used to drive the air guide plate 23 to rotate.

[0123] With this configuration, the air guide plate 23 can be rotated by rotating the drive component 24, and the angle of the air guide plate 23 can be adjusted to achieve multi-angle air outlet, so that the air blown out by the indoor unit of the air conditioner can be accurately blown to the required area, thereby improving the comfort of using the indoor unit of the air conditioner.

[0124] In this embodiment, the rotation drive 24 can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. The type of rotation drive 24 can be chosen flexibly, specifically according to actual needs, and this embodiment does not impose any specific limitations on this.

[0125] In some embodiments, such as Figure 1 As shown, the height of the indoor unit of the air conditioner is h, where h ≥ 200 mm and h ≤ 292 mm.

[0126] This design allows the height of the indoor air conditioner unit to fit into most kitchen ceiling spaces, thus improving the applicability of the indoor air conditioner unit installation.

[0127] In this embodiment, the height h of the indoor unit of the air conditioner can be 292mm, 200mm, or any value within the range of 200mm-292mm. The height h of the indoor unit of the air conditioner is set flexibly. Specifically, it can be set according to actual needs. This embodiment does not impose any specific limitations on this.

[0128] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
