[0025] This application provides an indoor air conditioning unit to solve the problem that users cannot intuitively know the current operating mode of the air conditioner. The following description will be provided in conjunction with the accompanying drawings.

[0026] In the embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the indoor unit of the air conditioner includes: The main body 1 includes an air cavity 13, a first air duct 11, and a second air duct 12. The air cavity 13 houses a fan 14 and is configured to communicate with an indoor space. The first air duct 11 is movably equipped with a first damper 111, which allows the first air duct 11 to communicate with or not communicate with the air cavity 13. The second air duct 12 is movably equipped with a second damper 121, which allows the second air duct 12 to communicate with or not communicate with the air cavity 13. The shield 2 is movably mounted on the main body 1 to open or close the air cavity 13; The first air duct 11 is configured to connect to the indoor unit and is equipped with an air purifier, while the second air duct 12 is configured to connect to the outdoor unit. The first air duct 11 and the second air duct 12 are located on the air inlet side and air outlet side of the fan 14, respectively. The end of the first air duct 11 that connects to the indoor unit is rotatably connected to a fan wheel 3.

[0027] It should be noted that in this application, the indoor unit of the air conditioner can be either a wall-mounted unit or a floor-standing unit. The obstruction 2 allows airflow between the air cavity 13 and the indoor space. The first air duct 11 and the first air damper 111 facilitate airflow between the air cavity 13 and the indoor space. The second air duct 12 and the second air damper 121 facilitate airflow between the air cavity 13 and the outdoor space. "The first air duct 11 and the second air duct 12 are located on the air inlet side and air outlet side of the fan 14, respectively" means that air can be introduced or discharged through the first air duct 11, and air can be introduced or discharged through the second air duct 12.

[0028] It is understandable that by observing the positional relationship between the obstruction 2 and the air cavity 13, as well as the rotation state of the impeller 3, users can intuitively understand the airflow direction, and thus more accurately and quickly understand the current operating mode. In this application, the indoor unit of the air conditioner has at least a fresh air mode, a purification mode, and an exhaust mode. Specifically, when the obstruction 2 opens the air cavity 13, the first air damper 111 closes, and the second air damper 121 opens, outdoor airflow enters the air cavity 13 through the second air duct 12 and is then exhausted into the room. At this time, the impeller 3 is stationary, and users can understand that the indoor unit of the air conditioner is in fresh air mode by observing the open state of the obstruction 2 and the stationary state of the impeller 3. When the obstruction 2 opens the air cavity 13, the first air damper 111 opens, and the second air damper 121 closes, by turning on the purifier and the fan 14, indoor air is drawn into the first air duct 11, purified by the purifier, and then exhausted through the air cavity 13. At this time, users can understand that the indoor unit of the air conditioner is in purification mode by observing the open state of the obstruction 2 and the rotation of the impeller 3. When the shield 2 closes the air cavity 13, the first air damper 111 opens, and the second air damper 121 opens, the airflow is drawn into the first air duct 11 and discharged from the second air duct 12 by turning on the fan 14. At this time, the fan wheel 3 rotates, and the user can know that the indoor unit of the air conditioner is currently in exhaust mode by the closed state of the shield 2 and the rotation of the fan wheel 3.

[0029] In some embodiments, such as Figure 2 As shown, the indoor unit of the air conditioner also includes a smoke generator installed on the main body 1. The smoke generator is located near the end of the first air duct 11 that communicates with the indoor unit. When the shielding member 2 closes the air cavity 13, the smoke generated by the smoke generator is discharged to the outside through the first air duct 11 and the second air duct 12.

[0030] It should be noted that a smoke generator refers to a component used to produce visible smoke.

[0031] Understandably, in exhaust mode, the shield 2 closes the air cavity 13, and the fan 14 rotates to draw smoke into the first air duct 11. Compared to the rotation of the impeller 3, the smoke makes the airflow direction more concrete, and the user can more intuitively understand the current operating mode.

[0032] In some embodiments, such as Figure 2 As shown, the smoke generator is located inside the main body 1. The main body 1 is provided with a mist exhaust hole 15, which is located near the end of the first air duct 11 that connects to the room.

[0033] Understandably, by placing the smoke generator inside the main unit 1, the appearance of the indoor air conditioning unit is improved, and the smoke is smoothly discharged through the exhaust hole 15.

[0034] In some embodiments, such as Figure 2 as well as Figure 7 As shown, a decorative piece 4 is provided on the outer side of the main body 1. The decorative piece 4 is made of transparent material and has ventilation openings. The impeller 3 is positioned facing the decorative piece 4.

[0035] Understandably, by using a decorative element 4 to beautify the appearance, one end of the first air duct 11 is blocked, preventing debris from being drawn into the first air duct 11. At the same time, the decorative element 4, made of transparent material, allows the user to observe the rotation of the internal impeller 3. Airflow in and out of the first air duct 11 is achieved through ventilation openings.

[0036] For example, the wind turbine 3 may be disposed within the first air duct 11 or within the decorative element 4.

[0037] In some embodiments, such as Figure 7 As shown, the decorative component 4 includes an interconnected housing 41 and a plurality of guide ribs 42. The plurality of guide ribs 42 are spaced upward along the circumference of the impeller 3, and each guide rib 42 is arc-shaped.

[0038] It should be noted that the arc shape of the guide rib 42 should be set to facilitate the airflow into the first air duct 11.

[0039] Understandably, the curved guide ribs 42 guide the airflow into the first air duct 11 and act on the impeller 3, making it easier for the airflow to drive the impeller 3 to rotate. This allows the impeller 3 to respond quickly and accurately to different airflow rates and speeds, and the user can determine the gear level in the current mode by observing the rotation speed of the impeller 3.

[0040] In some embodiments, the impeller 3 is rotatably connected to the first air duct 11.

[0041] It should be noted that the wind turbine 3 is located inside the first air duct 11, rather than inside the decorative piece 4.

[0042] It is understandable that the decorative part 4 is set on the outside of the main body 1 and has a certain thickness. Setting the fan wheel 3 inside the first air duct 11 instead of inside the decorative part 4 can reduce the thickness of the decorative part 4, making the overall appearance of the air conditioner indoor unit more integrated and less obtrusive.

[0043] In some embodiments, such as Figure 2 As shown, decorative piece 4 is located on the left or right side of the main body 1.

[0044] It should be noted that when the indoor unit of the air conditioner is in the normal installation position, the side of the indoor unit facing the user is taken as the front side, and the left and right sides of the main unit 1 refer to the two sides of the main unit 1 in the horizontal direction.

[0045] It is understandable that placing decorative parts 4 on the left and right sides of the main unit 1 is to avoid occupying the space of the air outlet channel of the main unit 1, and to ensure that the fresh air supplied in the fresh air mode will not blow directly on the user, so as to ensure a good airflow.

[0046] In some embodiments, such as Figure 4 , Figure 5 as well as Figure 6 As shown, the first air duct 11 and the second air duct 12 are both located on one side of the fan 14 along the axial direction, and the shielding member 2 is located in the radial direction of the fan 14. The fan 14 is a centrifugal fan 14.

[0047] It should be noted that the centrifugal fan 14 has the characteristics of axial air intake and radial air outlet.

[0048] It is understandable that the placement of the first air duct 11, the second air duct 12, and the shielding component 2 is designed by utilizing the characteristics of the centrifugal fan 14, so that the airflow can flow in and out continuously, reducing aerodynamic noise.

[0049] In some embodiments, such as Figure 4As shown, the air cavity 13 includes a first air cavity 131 and a second air cavity 132 that are interconnected. The fan 14 is disposed in the first air cavity 131. The shielding member 2 movably opens or closes the second air cavity 132. The second air cavity 132 is located in the radial direction of the fan 14. The first air duct 11 and the second air duct 12 are both located on the same side in the axial direction of the fan 14. The second air damper 121 includes a fresh air damper 1211 and an exhaust air damper 1212. The fresh air damper 1211 connects the air inlet side of the first air chamber 131 with the second air duct 12, and the exhaust air damper 1212 connects to the second air chamber 132.

[0050] Understandably, in fresh air mode, the shield 2 is open, the first air damper 111 is closed, the fresh air damper 1211 is open, and the exhaust damper 1212 is closed. Airflow enters the room after passing through the second air duct 12, the first air chamber 131, and the second air chamber 132. In purification mode, the shield 2 is open, the first air damper 111 is open, the fresh air damper 1211 is closed, and the exhaust damper 1212 is closed. Indoor airflow is purified by the purifier in the first air duct 11 and then re-enters the room through the first air chamber 131 and the second air chamber 132. In exhaust mode, the shield 2 is closed, the first air damper 111 is open, the fresh air damper 1211 is closed, and the exhaust damper 1212 is open. Indoor airflow flows to the outside through the first air duct 11, the first air chamber 131, the second air chamber 132, and the second air duct 12.

[0051] Furthermore, the first air duct 11 and the second air duct 12 are located on the same side of the fan 14 along its axial direction, which facilitates manufacturing. Specifically, the first damper 111 and the fresh air damper 1211 are both located on the air inlet side of the fan 14.

[0052] For example, the second air duct 12 is provided with three air outlets, one of which is connected to the outside, and the other two air outlets are respectively connected to the fresh air damper 1211 and the exhaust air damper 1212.

[0053] In some embodiments, such as Figure 5 As shown, the shield 2 is located on the upper side of the main body 1. The shield 2 opens or closes the air cavity 13 in the direction close to or away from the main body 1. The impeller 3 is set close to the lower side of the main body 1.

[0054] It should be noted that the upper and lower sides of the main unit 1 refer to the two sides in the vertical direction, with the side of the indoor unit facing the user as the front side when the indoor unit is in the normal installation position.

[0055] It is understandable that even when the indoor unit of the air conditioner is installed at a high position, the positional change of the shield 2 and the movement of the fan wheel 3 can be observed.

[0056] In some embodiments, such as Figure 4As shown, the second air duct 12 is provided with a flow guide 5, which is located in the middle of the second air duct 12. The flow guide 5 is used to guide the airflow in the second air duct 12 to the fresh air damper 1211 or the exhaust damper 1212.

[0057] It is understandable that the flow guide 5 is used to reduce the noise generated when the airflow flows in the second air duct 12.

[0058] For example, the flow guide 5 is provided with two flow guide surfaces 51, one of which is spaced apart from the side wall of the second air duct 12 and extends in the direction close to the fresh air damper 1211, and the other flow guide surface 51 is spaced apart from the side wall of the second air duct 12 and extends in the direction close to the exhaust damper 1212.
