Description

Technical Field

[0001] This application relates to the field of home appliance technology, and in particular to an indoor unit of an air conditioner. Background Technology

[0002] With the continuous improvement of people's living standards, air conditioning has become a common means for regulating indoor temperature in daily life. Air conditioning is used to regulate indoor air, such as temperature, humidity, and air quality. Regarding air quality regulation, air conditioning incorporates a fresh air function, using a fresh air fan to deliver outdoor air into the room through the air conditioner's fresh air outlet. Regarding humidity regulation, air conditioning incorporates a humidification function, using humidifying components to generate humidified steam that is carried into the room along with the air through the fresh air outlet.

[0003] To deliver humidified steam and air into the room from multiple directions, some air conditioners have two opposing fresh air outlets on their outer casing. Therefore, how to evenly distribute the humidified steam generated by the humidification components to these two fresh air outlets for delivery into the room has become a pressing problem for these types of air conditioners. Utility Model Content

[0004] This application discloses an indoor air conditioning unit that operates with low noise and whose humidifying steam generated by the humidifying component can be evenly distributed to the first and second fresh air outlets for delivery into the room.

[0005] To achieve the above objectives, this application discloses an indoor unit for an air conditioner, comprising:

[0006] An outer casing, wherein an inner cavity is formed inside the outer casing;

[0007] The first fresh air outlet is formed on the first side of the outer shell and communicates with the inner cavity;

[0009] A fresh air fan is located in the inner cavity and is used to deliver outdoor fresh air to the room through the first fresh air outlet and the second fresh air outlet.

[0010] A humidifying assembly, disposed within the inner cavity, is used to generate humidifying steam; and

[0011] A conveying component is disposed in the inner cavity, and the conveying component includes:

[0012] The inlet end is connected to the humidification component to receive the humidifying steam generated by the humidification component;

[0013] A first conveying section, the first conveying section having a first outlet end facing the first fresh air outlet, so that the humidifying steam flowing out of the conveying component is conveyed to the room through the first fresh air outlet;

[0014] The second conveying section is connected to the first conveying section and forms the inlet end at the connection point. The second conveying section has a second outlet end facing the second fresh air outlet so that the humidifying steam flowing out of the conveying component is delivered to the room through the second fresh air outlet.

[0015] Wherein, along the width direction of the indoor unit of the air conditioner, the ratio of the length of the first conveying section to the length of the second conveying section is a, the ratio of the cross-sectional area of ​​the first outlet end to the cross-sectional area of ​​the second outlet end is b, ba≥-0.2, ba≤0.2.

[0016] In some embodiments of this application, b = a.

[0017] In some embodiments of this application, the ratio 'a' of the length of the first conveying segment to the length of the second conveying segment satisfies: a > 1, a ≤ 1.6.

[0018] In some embodiments of this application, the ratio b of the cross-sectional area of ​​the first outlet end to the cross-sectional area of ​​the second outlet end satisfies: b > 1, b ≤ 1.6.

[0019] In some embodiments of this application, the distance between the first outlet end and the first fresh air outlet is equal to the distance between the second outlet end and the second fresh air outlet.

[0020] In some embodiments of this application, the first conveying section includes a first extension, a second extension, and a third extension. The second extension extends along the thickness direction of the indoor air conditioning unit and its two ends are respectively connected to the first extension and the third extension. The end of the third extension away from the second extension forms the first outlet end. Along the thickness direction, the first outlet end is located in the middle of the first fresh air outlet.

[0021] The second conveying section includes a fourth extension, a fifth extension, and a sixth extension. The fourth extension is connected to the first extension and forms the inlet end at the connection. The fifth extension extends along the thickness direction and its two ends are connected to the fourth extension and the sixth extension, respectively. The end of the sixth extension away from the fifth extension forms the second outlet end. Along the thickness direction, the second outlet end is located in the middle of the second fresh air outlet.

[0022] In some embodiments of this application, the outer shell is provided with a partition, and along the height direction of the outer shell, the partition is used to divide the inner cavity into a first inner cavity and a second inner cavity located on the upper and lower sides of the partition;

[0023] The fresh air fan is located in the second inner cavity, the air outlet of the fresh air fan is connected to the first inner cavity, and the first fresh air outlet and the second fresh air outlet are connected to the first inner cavity.

[0024] The humidification component is disposed in the second inner cavity, the inlet end is disposed facing the humidification component, and the first outlet end and the second outlet end are located in the first inner cavity.

[0025] In some embodiments of this application, the partition is provided with a through portion connecting the first inner cavity and the second inner cavity;

[0026] The inlet end is provided with an interface, which protrudes through the through portion into the second inner cavity and is connected to the humidification component through a pipeline.

[0027] In some embodiments of this application, along the width direction, the connection between the inlet end and the humidification component is located on one side of the centerline of the indoor unit of the air conditioner.

[0028] In some embodiments of this application, along the height direction of the indoor unit of the air conditioner, the length of the first outlet end is equal to the length of the second outlet end, and along the thickness direction of the indoor unit of the air conditioner, the width of the first outlet end is d1, the width of the second outlet end is d2, and d1 / d2 = b.

[0029] Compared with the prior art, this application has at least the following beneficial effects:

[0030] In this embodiment, an inner cavity is formed within the outer shell, along with a first fresh air outlet and a second fresh air outlet communicating with the inner cavity. A humidification component and a conveying component are housed within the inner cavity. A first conveying section and a second conveying section of the conveying component are connected, with an inlet end formed at the connection point. This inlet end communicates with the humidification component to receive the humidifying steam generated by the humidification component. The first outlet end of the first conveying section and the second outlet end of the second conveying section face the first and second fresh air outlets, respectively, so that the humidifying steam flowing out of the conveying component is conveyed into the room through the first and second fresh air outlets. Simultaneously, a fresh air fan is installed within the inner cavity, which conveys outdoor fresh air into the room through the fresh air outlets. Simultaneously, the outdoor fresh air carries the humidifying steam into the room along with the fresh air as it passes through the first and second fresh air outlets, thereby regulating and improving the indoor air humidity and quality.

[0031] Furthermore, if the ratio of the length of the first conveying section to the length of the second conveying section is *a*, then the ratio of the humidifying steam velocity at the first outlet end to the humidifying steam velocity at the second outlet end is approximately *a*, and the ratio of the cross-sectional area at the first outlet end to the cross-sectional area at the second outlet end is *b*, such that the ratios *a* and *b* satisfy: *ba* ≥ -0.2, *ba* ≤ 0.2. Since the flow rate of the humidifying steam at the first outlet end is equal to the product of the humidifying steam velocity at the first outlet end and the cross-sectional area at the first outlet end, and the flow rate of the humidifying steam at the second outlet end is equal to the product of the humidifying steam velocity at the second outlet end and the cross-sectional area at the second outlet end, the flow rates of the humidifying steam at the first outlet end and the second outlet end differ by less than 20%. This small flow rate difference allows the humidifying steam generated by the humidification component to be distributed relatively evenly to the first and second fresh air outlets for delivery into the room.

[0050] Before explaining the technical solution of this application, the inventive concept of this application will be explained first.

[0051] Figure 1 and Figure 2 This is a structural schematic diagram of an air conditioner indoor unit 100 provided in an embodiment of this application. Figure 3 This is a schematic diagram of a fresh air fan 40 installed on the outer casing 10 according to an embodiment of this application. Figure 4 This is a schematic diagram of a humidification component 20 installed on a housing 10 according to an embodiment of this application. Figure 3 As shown, the humidifying component 20 is a device installed in the inner cavity 101 of the outer casing 10 of the indoor unit 100 of an air conditioner, used to generate humidifying steam to regulate indoor air humidity. Figure 4 As shown, the fresh air fan 40 is a device installed in the inner cavity 101 of the outer casing 10 of the indoor unit 100 of the air conditioner, used to deliver fresh outdoor air to the room to regulate the indoor air quality.

[0052] Normally, the humidifying steam generated by the humidifier unit is transported through pipes to the vicinity of the fresh air outlet. While the fresh air fan 40 outputs fresh air from the inner cavity 101 of the outer casing 10 to the room through the fresh air outlet, it also carries away the humidifying steam. To improve the user experience, some air conditioners now have two opposing fresh air outlets on the outer casing 10, enabling the delivery of humidifying steam and air to the room from multiple directions. Therefore, the humidifying steam generated by the humidifier unit 20 needs to be distributed via a delivery pipe. The two delivery sections of the pipe divide the humidifying steam into two paths, allowing each path to flow out of the pipe towards one of the two fresh air outlets.

[0053] However, how to evenly distribute the humidifying steam generated by the humidifying component 20 to the two fresh air outlets for delivery into the room has become a pressing problem for this type of air conditioner. Based on this, this application provides an indoor air conditioner unit 100 to solve the aforementioned problem.

[0054] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0055] In some embodiments, such as Figure 1 and Figure 3 As shown, the indoor unit 100 of the air conditioner includes a housing 10, and an inner cavity 101 is formed inside the housing 10.

[0056] The inner cavity 101 can be cylindrical or cuboid, etc. Of course, the inner cavity 101 can be other possible shapes, and this embodiment does not limit it.

[0057] In some embodiments, the indoor unit 100 of the air conditioner includes a first fresh air outlet 102, which is formed in the outer casing 10 and communicates with the inner cavity 101.

[0058] The first fresh air outlet 102 is connected to the inner cavity 101, and the first fresh air outlet 102 can provide a channel for the air in the inner cavity 101 to be blown out to the outside of the outer shell 10.

[0059] In some embodiments, such as Figure 2 and Figure 3 As shown, the indoor unit 100 of the air conditioner includes a second fresh air outlet 103, which is formed on the outer casing 10 and communicates with the inner cavity 101.

[0060] The second fresh air outlet 103 is connected to the inner cavity 101, and the second fresh air outlet 103 can provide a channel for the air in the inner cavity 101 to be blown to the outside of the outer shell 10.

[0061] Thus, when the indoor unit 100 of the air conditioner includes a first fresh air outlet 102 and a second fresh air outlet 103, the air in the inner cavity 101 has multiple channels to be blown out to the outside of the outer casing 10, and the efficiency of blowing the air out of the outer casing 10 is relatively high.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, the first fresh air outlet 102 is formed on the first side 10a of the outer casing 10, and the second fresh air outlet 103 is formed on the second side 10b of the outer casing 10. The second side 10b is the side of the outer casing 10 opposite to the first side 10a.

[0063] The first fresh air outlet 102 and the second fresh air outlet 103 are respectively distributed on the first side 10a and the second side 10b opposite to the outer shell 10, so that the first fresh air outlet 102 and the second fresh air outlet 103 face different directions, thereby realizing the delivery of air from multiple directions into the indoor cavity 101.

[0064] In some embodiments, such as Figure 3 As shown, the indoor unit 100 of the air conditioner includes a humidification component 20, which is disposed in the inner cavity 101 and is used to generate humidifying steam.

[0065] By providing a humidification component 20 in the inner cavity 101, the humidification component 20 can generate humidifying steam. The humidifying steam can be blown out from the fresh air outlet to the outside of the outer casing 10 along with the air in the inner cavity 101, thereby regulating the air humidity in the room where the air conditioner indoor unit 100 is located.

[0066] In some embodiments, such as Figure 4 As shown, the indoor unit 100 of the air conditioner includes a fresh air fan 40, which is located in the inner cavity 101. The fresh air fan 40 is used to deliver outdoor fresh air to the indoor unit through the first fresh air outlet 102 and the second fresh air outlet 103.

[0067] By installing a fresh air fan 40 in the inner cavity 101, the fresh air fan 40 can output outdoor fresh air to the indoor through the fresh air outlet. At the same time, the outdoor fresh air can carry humidifying steam when passing through the first fresh air outlet 102 and the second fresh air outlet 103, so that the humidifying steam can be delivered to the indoor as well.

[0068] In some embodiments, such as Figure 3 As shown, the indoor unit 100 of the air conditioner includes a conveying component 30, which is disposed in the inner cavity 101.

[0069] By providing a conveying component 30 in the inner cavity 101, the humidifying steam generated by the humidifying component 20 is conveyed towards the first fresh air outlet 102 and the second fresh air outlet 103, shortening the path of the humidifying steam blown out of the inner cavity 101 to the outside of the outer casing 10, thereby improving the humidification speed and humidification efficiency of the air conditioning indoor unit 100.

[0070] In some embodiments, the conveying component 30 includes an inlet end 30a connected to the humidification assembly 20 to receive humidifying steam generated by the humidification assembly 20.

[0071] The humidifying steam generated by the humidifying unit 20 is connected to the humidifying component 20 through the inlet end 30a of the conveying component 30 and is conveyed through the conveying component 30.

[0072] In some embodiments, such as Figure 5 and Figure 6 As shown, the conveying component 30 includes a first conveying section 31, which has a first outlet end 30b facing a first fresh air outlet 102, so that the humidifying steam flowing out of the conveying component 30 is conveyed to the room through the first fresh air outlet 102.

[0073] The humidifying steam received at the inlet end 30a is transported through the first conveying section 31, and the first outlet end 30b is directed toward the first fresh air outlet 102, so that the humidifying steam generated by the humidifying component 20 is transported toward the first fresh air outlet 102 and from the first fresh air outlet 102 to the room. This shortens the path of the humidifying steam along with the air in the inner cavity 101 through the first fresh air outlet 102 to the outside of the outer casing 10, thereby improving the humidification speed and humidification efficiency of the air conditioning indoor unit 100.

[0074] In some embodiments, the conveying component 30 includes a second conveying section 32, which is connected to the first conveying section 31 and forms an inlet end 30a at the connection. The second conveying section 32 has a second outlet end 30c, which faces the second fresh air outlet 103, so that the humidifying steam flowing out of the conveying component 30 is conveyed to the room through the second fresh air outlet 103.

[0075] The humidifying steam received at the inlet end 30a is transported via the second conveying section 32, and the second outlet end 30c is directed toward the second fresh air outlet 103, so that the humidifying steam generated by the humidifying component 20 is transported toward the second fresh air outlet 103 and from the second fresh air outlet 103 to the room. This shortens the path of the humidifying steam along with the air in the inner cavity 101 through the second fresh air outlet 103 to the outside of the outer casing 10, thereby improving the humidification speed and humidification efficiency of the air conditioning indoor unit 100.

[0076] In some embodiments, along the width direction x of the indoor unit 100, the ratio of the length of the first conveying section 31 to the length of the second conveying section 32 is a, the ratio of the cross-sectional area of ​​the first outlet end 30b to the cross-sectional area of ​​the second outlet end 30c is b, ba≥-0.2, ba≤0.2.

[0077] Since the ratio of the length of the first conveying section 31 to the length of the second conveying section 32 is a, the ratio of the flow velocity of the humidifying steam at the first outlet end 30b to the flow velocity of the humidifying steam at the second outlet end 30c is approximately a. The ratio of the cross-sectional area of ​​the first outlet end 30b to the cross-sectional area of ​​the second outlet end 30c is b, such that the ratios a and b satisfy: ba ≥ -0.2, ba ≤ 0.2. Since the flow rate of humidifying steam at the first outlet 30b is equal to the product of the flow velocity of humidifying steam at the first outlet 30b and the cross-sectional area of ​​the first outlet 30b, and the flow rate of humidifying steam at the second outlet 30c is equal to the product of the flow velocity of humidifying steam at the second outlet 30c and the cross-sectional area of ​​the second outlet 30c, the flow rate difference between the humidifying steam at the first outlet 30b and the humidifying steam at the second outlet 30c is within 20%, the flow rate difference is small, and the humidifying steam generated by the humidifying component 20 can be more evenly distributed to the first fresh air outlet 102 and the second fresh air outlet 103 for delivery to the room.

[0078] Taking the first conveying section 31 as an example, the length of the first conveying section 31 can be understood as the length of the conveying path through which humidifying steam is transported from the inlet end 30a to the first outlet end 30b via the first conveying section 31.

[0079] In some embodiments, b = a.

[0080] By making b=a so that the flow rate of humidifying steam at the first outlet 30b is equal to the flow rate of humidifying steam at the second outlet 30c, the humidifying steam generated by the humidifying component 20 can be evenly distributed to the first fresh air outlet 102 and the second fresh air outlet 103 to be delivered to the room.

[0081] In some embodiments, the ratio a of the length of the first conveying section 31 to the length of the second conveying section 32 satisfies: a > 1.

[0082] By making the length of the first conveying section 31 different from the length of the second conveying section 32, the conveying component 30 can be positioned in the outer casing 10 that is biased toward the first fresh air outlet 102 or the second fresh air outlet 103 rather than in the center, which facilitates the layout of the conveying component 30 and other components inside the outer casing 10, making the overall structure of the air conditioning indoor unit 100 more compact.

[0083] The ratio 'a' of the length of the first conveying section 31 to the length of the second conveying section 32 can be 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, etc., and this embodiment does not impose a specific limitation on it.

[0084] In some embodiments, the ratio a of the length of the first conveying section 31 to the length of the second conveying section 32 satisfies: a≤1.6.

[0085] If the ratio a of the length of the first conveying section 31 to the length of the second conveying section 32 is a > 1.6, then the length difference between the first conveying section 31 and the second conveying section 32 is large. After the humidifying steam generated by the humidifying component 20 enters the conveying component 30 through the inlet end 30a, a large amount of humidifying steam flows to the second conveying section 32, while a small amount of humidifying steam flows to the first conveying section 31. Moreover, since the first conveying section 31 is longer, the humidifying steam condenses in the first conveying section 31 to form more steam condensate, resulting in less humidifying steam output from the first outlet end 30b. Thus, the humidifying steam output from the second outlet end 30c is much more than the humidifying steam output from the first outlet end 30b. It is difficult to evenly distribute the humidifying steam generated by the humidifying component 20 to the first fresh air outlet 102 and the second fresh air outlet 103 for delivery to the room.

[0086] Therefore, the ratio a of the length of the first conveying section 31 to the length of the second conveying section 32 can be a≤1.6. The humidifying steam output from the second outlet end 30c is less different from the humidifying steam output from the first outlet end 30b. The humidifying steam generated by the humidifying component 20 can be distributed relatively evenly to the first fresh air outlet 102 and the second fresh air outlet 103 to be delivered to the room.

[0087] The ratio 'a' of the length of the first conveying section 31 to the length of the second conveying section 32 can be 1.6, 1.5, 1.4, 1.3, 1.2, 1.1, 1, etc., and this embodiment does not impose a specific limitation on it.

[0088] In some embodiments, the ratio b of the cross-sectional area of ​​the first outlet end 30b to the cross-sectional area of ​​the second outlet end 30c satisfies: b > 1.

[0089] By making the cross-sectional area of ​​the first outlet end 30b different from that of the second outlet end 30c, the cross-sectional areas of the first outlet end 30b and the second outlet end 30c can be adjusted according to the different ratios of the length of the first conveying section 31 to the length of the second conveying section 32, so that the ratios a and b are closer.

[0090] The ratio b of the cross-sectional area of ​​the first outlet end 30b to the cross-sectional area of ​​the second outlet end 30c can be 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, etc., and this embodiment does not make a specific limitation on it.

[0091] In some embodiments, the ratio b of the cross-sectional area of ​​the first outlet end 30b to the cross-sectional area of ​​the second outlet end 30c satisfies: b≤1.6.

[0092] If the ratio b of the cross-sectional area of ​​the first outlet end 30b to the cross-sectional area of ​​the second outlet end 30c is greater than 1.6, then the cross-sectional area of ​​the first outlet end 30b and the cross-sectional area of ​​the second outlet end 30c are significantly different. After the humidifying steam generated by the humidifying component 20 enters the conveying component 30 through the inlet end 30a, the humidifying steam is difficult to flow out from the second outlet end 30c. Meanwhile, the flow rate of the humidifying steam flowing out from the first outlet end 30b is low. Therefore, the humidifying steam generated by the humidifying component 20 is difficult to distribute evenly to the first fresh air outlet 102 and the second fresh air outlet 103 for delivery to the room.

[0093] Therefore, the ratio b of the cross-sectional area of ​​the first outlet end 30b to the cross-sectional area of ​​the second outlet end 30c can be b≤1.6. The difference between the cross-sectional areas of the first outlet end 30b and the second outlet end 30c is small, and the humidifying steam generated by the humidifying component 20 can be distributed relatively evenly to the first fresh air outlet 102 and the second fresh air outlet 103 to be delivered to the room.

[0094] The ratio b of the cross-sectional area of ​​the first outlet end 30b to the cross-sectional area of ​​the second outlet end 30c can be 1.6, 1.5, 1.4, 1.3, 1.2, 1.1, 1, etc., and this embodiment does not make a specific limitation on it.

[0095] In some embodiments, the distance between the first outlet end 30b and the first fresh air outlet 102 is equal to the distance between the second outlet end 30c and the second fresh air outlet 103.

[0096] The distance between the first outlet end 30b and the first fresh air outlet 102 is equal to the distance between the second outlet end 30c and the second fresh air outlet 103, so that the humidifying steam output from the first fresh air outlet 102 and the second fresh air outlet 103 to the room can be distributed more evenly.

[0097] In some embodiments, such as Figure 6 and Figure 7 As shown, the first conveying section 31 includes a first extension 311, a second extension 312 and a third extension 313. The second extension 312 extends along the thickness direction y of the indoor air conditioning unit 100 and its two ends are respectively connected to the first extension 311 and the third extension 313. The end of the third extension 313 away from the second extension 312 forms a first outlet end 30b. Along the thickness direction y, the first outlet end 30b is located in the middle of the first fresh air outlet 102.

[0098] The second extension 312 extends along the thickness direction y of the indoor unit 100 of the air conditioner, and its two ends are respectively connected to the first extension 311 and the second extension 312, so that the humidifying steam of the first extension 311 can be transported to the third extension 313 through the second extension 312, and the third extension 313 is offset relative to the first extension 311 along the thickness direction y, so that the first outlet end 30b is located in the middle of the first fresh air outlet 102 along the thickness direction y, and the humidifying steam can be evenly transported from the first fresh air outlet 102 to the room.

[0099] In some embodiments, the second conveying section 32 includes a fourth extension 321, a fifth extension 322, and a sixth extension 323. The fourth extension 321 is connected to the first extension 311 and forms an inlet end 30a at the connection. The fifth extension 322 extends along the thickness direction y and its two ends are connected to the fourth extension 321 and the sixth extension 323, respectively. The end of the sixth extension 323 away from the fifth extension 322 forms a second outlet end 30c. Along the thickness direction y, the second outlet end 30c is located in the middle of the second fresh air outlet 103.

[0100] The fifth extension 322 extends along the thickness direction y of the indoor unit 100 of the air conditioner, and its two ends are respectively connected to the fourth extension 321 and the sixth extension 323, so that the humidifying steam of the fourth extension 321 can be transported to the sixth extension 323 through the fifth extension 322, and the sixth extension 323 is offset relative to the fourth extension 321 along the thickness direction y, so that the second outlet end 30c is located in the middle of the second fresh air outlet 103 along the thickness direction y, and the humidifying steam can be evenly transported from the second fresh air outlet 103 to the room.

[0101] In some embodiments, such as Figure 8 As shown, the outer shell 10 is provided with a partition 11. Along the height direction z of the outer shell 10, the partition 11 is used to divide the inner cavity 101 into a first inner cavity 101a and a second inner cavity 101b located on the upper and lower sides of the partition 11. The first fresh air outlet 102 and the second fresh air outlet 103 are connected to the first inner cavity 101a.

[0102] By providing a partition 11 in the outer casing 10, the inner cavity 101 is divided into a first inner cavity 101a and a second inner cavity 101b. The first fresh air outlet 102 and the second fresh air outlet 103 are connected to the first inner cavity 101a. In this way, components of the air conditioning indoor unit 100, such as the fresh air fan 40, can be installed in the second inner cavity 101b, and the second inner cavity 101b can be used to collect air and humidifying steam, and to output both to the outside of the outer casing 10 from the first fresh air outlet 102 and the second fresh air outlet 103.

[0103] In some embodiments, such as Figure 9 As shown, the fresh air fan 40 is located in the second inner cavity 101b, and the fan outlet 40a of the fresh air fan 40 is connected to the first inner cavity 101a.

[0104] A fresh air fan 40 is installed in the second inner cavity 101b. The air outlet 40a of the fresh air fan 40 is connected to the first inner cavity 101a. The fresh air fan 40 can deliver outdoor fresh air from the air outlet to the first inner cavity 101a, and output it to the outside of the outer shell 10 via the first fresh air outlet 102 and the second fresh air outlet 103.

[0105] In some embodiments, the humidification component 20 is disposed in the second inner cavity 101b, the inlet end 30a is disposed toward the humidification component 20, and the first outlet end 30b and the second outlet end 30c are located in the first inner cavity 101a.

[0106] A humidifying component 20 is installed in the second inner cavity 101b, and a conveying component 30 is installed in the partition 11, with the inlet end 30a facing the humidifying component 20 to facilitate communication between the inlet end 30a and the humidifying component 20. Simultaneously, the outlet end is located in the first inner cavity 101a, allowing the humidifying steam output from the first outlet end 30b and the second outlet end 30c to be conveyed towards the first fresh air outlet 102 and the second fresh air outlet 103.

[0107] In some embodiments, the partition 11 is provided with a through portion 11a that connects the first inner cavity 101a and the second inner cavity 101b, and the inlet end 30a is provided with an interface 33. The interface 33 protrudes through the through portion 11a to the second inner cavity 101b and is connected to the humidification assembly 20 through a pipeline.

[0108] By providing a through section 11a in the partition section 11, the through section 11a connects the first inner cavity 101a and the second inner cavity 101b. The interface 33 provided at the inlet end 30a protrudes into the second inner cavity 101b through the through section 11a, which can avoid the interface 33 and facilitate the connection between the interface 33 and the humidification component 20.

[0109] In some embodiments, such as Figure 10 As shown, along the width direction x, the connection between the inlet end 30a and the humidification component 20 is located on one side of the center line a of the indoor unit 100 of the air conditioner.

[0110] By having the connection point between the inlet end 30a and the humidification component 20 located on one side of the centerline a of the air conditioner indoor unit 100, the conveying component 30 can be positioned on the outer casing 10 at a position biased towards the first fresh air outlet 102 or the second fresh air outlet 103 rather than in the center. This facilitates the layout of the conveying component 30 and other components within the outer casing 10, making the overall structure of the air conditioner indoor unit 100 more compact.

[0111] In some embodiments, along the height direction z of the air conditioner indoor unit 100, the length of the first outlet end 30b is equal to the length of the second outlet end 30c, and along the thickness direction y of the air conditioner indoor unit 100, the width of the first outlet end 30b is d1, the width of the second outlet end 30c is d2, and d1 / d2 = b.

[0112] By ensuring that the lengths of the first outlet end 30b and the second outlet end 30c are equal, the space occupied by the first outlet end 30b and the second outlet end 30c in the height direction z of the inner cavity 101 is the same. However, by utilizing the fact that the widths of the first outlet end 30b and the second outlet end 30c are unequal, the ratio of the cross-sectional area of ​​the first outlet end 30b to the cross-sectional area of ​​the second outlet end 30c is b. At the same time, the first outlet end 30b and the second outlet end 30c are always covered by the first fresh air outlet 102 and the second fresh air outlet 103, respectively. The humidifying steam flowing out of the first outlet end 30b and the second outlet end 30c can flow to the first fresh air outlet 102 and the second fresh air outlet 103, respectively.

This document uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand an air conditioner indoor unit and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
