[0048] The existing technology generally adopts the method of controlling the fan to reverse and realize the reverse air outlet of the fan, so that the indoor unit can realize the purpose of horizontal and vertical air supply at the same time. Since there are impurities such as dust in the air, it will affect the normal operation of the indoor unit after entering the indoor unit. It is necessary to set a filter structure at the air outlet of the indoor unit to filter the gas. However, the filter structure in the existing technology cannot meet the air flow direction requirements of the indoor unit. In particular, when there is an air outlet of the filter structure as the air outlet, the filter structure will cause the problem of increased wind resistance of the indoor unit, and the dust on the filter structure will be blown back into the room, seriously affecting the working efficiency of the indoor unit and the user experience. To this end, the present application provides a method such as Figures 1 to 10The air outlet assembly shown includes: an air outlet frame 1, on which an air outlet is provided; an air guide structure 2, which is rotatably provided on the air outlet frame 1, and the air guide structure 2 has a first state of closing the air outlet and a second state of opening the air outlet; a filtering structure 3, which is rotatably provided on the air outlet frame 1, and the filtering structure 3 has a filtering state of shielding the air outlet for filtering and a avoiding state of avoiding the air outlet; when the air guide structure 2 is in the second state and the filtering structure 3 is in the avoiding state, the filtering surface of the filtering structure 3, the inner side surface of the air guide structure 2 and the air outlet frame 1 located between the filtering structure 3 and the air guide structure 2 together form a dust collecting space 10. By utilizing the rotatable air guide structure 2 and the filtering structure 3, the air can be adjusted according to the air flow direction at the air outlet and the working state of the air duct machine corresponding to the air outlet component. When the air outlet is used as an air outlet, the air guide structure 2 and the filtering structure 3 both avoid the air flow to ensure the air outlet effect of the air outlet, and the filtering surface of the filtering structure 3, the inner side of the air guide structure 2 and the air outlet frame 1 together form a dust collecting space 10. The collision generated at the moment of contact between the filtering structure 3 and the air guide structure 2 and the air flow passing through the leeward side of the filtering structure 3 can cause the impurities on the filtering structure 3 to fall off and be collected by the dust collecting space 10, which can avoid The dust on the filter structure 3 is blown into the room and affects the user experience, but it can also clean the filter structure 3 and prepare for the next filtering of the filter structure. When the air outlet is used as an air inlet, the filter structure 3 can cover the air outlet for filtering, thereby achieving reliable filtration of the gas. When the air outlet component does not need to work, the air guide structure 2 is controlled to switch to the first state to close the air outlet, preventing dust, small animals, etc. from entering through the air outlet, thereby ensuring the reliable operation of the duct machine. At the same time, the air guide structure 2 can also prevent users from directly observing the internal structure of the duct machine through the air outlet, thereby improving the appearance of the duct machine.

[0049] The indoor unit further comprises a dust collecting structure, which is detachably mounted in the dust collecting space 10. When the air guide structure 2 is in the second state and the filter structure 3 is in the avoidance state, impurities on the filter structure 3 will enter the dust collecting space 10 and eventually accumulate on the dust collecting structure. The user can remove the dust collecting structure to clean the impurities, thereby preventing the impurities from being carried by the air flow to the filter structure 3 again, thereby ensuring the filtering effect and ventilation effect of the filter structure 3, and thus improving the working efficiency of the indoor unit. Preferably, the dust collecting structure comprises a dust collecting box, and an installation slot is provided on the air outlet frame 1. The dust collecting box is detachably mounted in the installation slot, and the opening of the dust collecting box is connected to the dust collecting space 10. Impurities on the filter structure 3 can accumulate in the dust collecting box. When the dust collecting box needs to be cleaned, the dust collecting box can be pulled out of the installation slot for cleaning.

[0050] The air outlet frame 1 has a lower crossbeam, on which a first rotating support structure 11 and a second rotating support structure 12 are provided. The lower portion of the air guide structure 2 is rotatably connected to the first rotating support structure 11. The lower portion of the filter structure 3 is rotatably connected to the second rotating support structure 12. When the air guide structure 2 switches from the first state to the second state, the air guide structure 2 and the filter structure 3 both rotate around the lower crossbeam, so that the air guide structure 2 in the second state and the filter structure 3 in the avoidance state can cooperate with each other to blow the airflow blown out of the air outlet diagonally upward. During cooling, cold air can be blown out through the air outlet and flow diagonally upward under the guidance of the air guide structure 2 and the filter structure 3, thereby increasing the air supply distance of the cold air and reducing the problem of cold air flowing rapidly downward due to gravity, thereby improving the waterfall cooling effect and user experience. The provision of the first rotating support structure 11 and the second rotating support structure 12 enables the air guide structure 2 and the filter structure 3 to rotate independently, ensuring the reliable operation of the air guide structure 2 and the filter structure 3.

[0051] A clearance distance is provided between the first rotating support structure 11 and the second rotating support structure 12. The clearance distance prevents interference between the air guide structure 2 and the filter structure 3, thereby ensuring the reliability of the air outlet assembly. Furthermore, the clearance distance facilitates the arrangement of the dust collection space 10, increases the size of the dust collection space 10, and facilitates cleaning of the dust collection space 10.

[0052] As an embodiment, the lower part of the air-guiding structure 2 is hinged to the first rotating support structure 11 through a support member 4, and the shape of the support member 4 is one or a combination of arc, V-shape or U-shape. The support member 4 is used to adjust the rotation radius of the air-guiding structure 2, so that during the rotation of the air-guiding structure 2, the rotation radius of the lower edge of the air-guiding structure 2 is greater than the distance between the lower edge of the air-guiding structure 2 and the filtering structure 3, and is also greater than the distance between the lower edge of the air-guiding structure 2 and the air outlet frame 1, thereby avoiding the filtering structure 3 and the air outlet frame 1, ensuring the reliability of the air-guiding structure 2, and the support member 4 located in the middle of the air-guiding structure 2 can also reliably support the air-guiding structure 2, preventing the air-guiding structure 2 from sagging due to excessive length, thereby improving the structural reliability of the air-guiding structure 2.

[0053] In the height direction of the tuyere frame 1, the numerical range of the distance L1 between the rotation axis of the air guide structure 2 and the rotation axis of the filter structure 3 is 0≤L1≤25mm. When the distance L1 is too large, the height of the tuyere frame 1 will be too large, affecting the overall volume of the tuyere assembly. When the distance L1 is too small, the avoidance reliability between the air guide structure 2, the filter structure 3 and the tuyere frame 1 cannot be reliably guaranteed. Only when 0≤L1≤25mm can the reliable rotation of the air guide structure 2 be guaranteed while reducing the volume of the tuyere assembly as much as possible, thereby improving the application capability of the tuyere assembly. Preferably, 5≤L1≤20mm.

[0054] In the thickness direction of the tuyere frame 1, the numerical range of the distance L2 between the rotation axis of the air guide structure 2 and the rotation axis of the filter structure 3 is 5mm≤L2≤60mm. When the distance L2 is too large, the thickness of the tuyere frame 1 will be larger, affecting the overall volume of the tuyere assembly. When the distance L2 is too small, the avoidance reliability between the air guide structure 2, the filter structure 3 and the tuyere frame 1 cannot be reliably guaranteed. Only when 5mm≤L2≤60mm can the reliable rotation of the air guide structure 2 be guaranteed while reducing the volume of the tuyere assembly as much as possible, thereby improving the application capability of the tuyere assembly. Preferably, 20mm≤L2≤40mm.

[0055] The tuyere assembly further includes a drive structure, which is disposed on the tuyere frame 1 and is in transmission connection with the air guide structure 2 and / or in transmission connection with the filtering structure 3. The drive structure can drive the air guide structure 2 and / or the filtering structure 3 to rotate, thereby switching the air guide structure 2 between the first state and the second state and switching the filtering structure 3 between the filtering state and the avoidance state.

[0056] Specifically, the drive structure includes an air guide drive 5 and a filter drive 6. The air guide structure 2 is connected to the air guide drive 5, and the air guide drive 5 can drive the air guide structure 2 to switch between the first state and the second state. The filter structure 3 is connected to the filter drive 6, and the filter drive 6 can drive the filter structure 3 to switch between the filter state and the avoidance state. The air guide drive 5 and the filter drive 6 are two separate power structures, ensuring that the air guide structure 2 and the filter structure 3 can operate independently and ensure that the air guide structure 2 and the filter structure 3 can operate reliably.

[0057] Since the air guide structure 2 needs to completely cover the air outlet frame 1, the overall size of the air guide structure 2 is relatively large. Therefore, the lower part of the air guide structure 2 is hinged to the air outlet frame 1, and the upper part of the air guide structure 2 is connected to the driving structure through a transmission part. The transmission part is used to push or pull the upper part of the air guide structure 2 to ensure that the movement of the air guide structure 2 is reliable.

[0058] The air outlet assembly also includes a reinforcing structure 7, which is arranged at the air outlet, and the edge of the reinforcing structure 7 is in abutment with the edge of the air outlet. The reinforcing structure 7 is used to improve the structural strength of the air outlet frame 1, and at the same time, it can also prevent the user from directly observing the internal structure of the air duct machine through the air outlet when the air guide structure 2 is opened, thereby improving the appearance of the air duct machine. The reinforcing structure 7 can be a plurality of ribs, and gas circulation channels can be formed between the ribs to ensure reliable gas flow in the air outlet. The ribs include horizontal ribs and vertical ribs, the upper end of the vertical ribs is arranged on the upper crossbeam of the air outlet frame 1, and the lower end of the upper end of the vertical ribs is arranged on the lower crossbeam of the air outlet frame 1. The two ends of the horizontal ribs are respectively connected to the left longitudinal beam and the right longitudinal beam of the air outlet frame 1 to achieve support.

[0059] The air outlet assembly is applied to the duct machine, and the duct machine has a side air outlet 81 and a lower air outlet 82. The air outlet assembly is arranged at the side air outlet 81. When the duct machine is cooling, it will discharge air horizontally to achieve waterfall cooling. At this time, the side air outlet 81 is used for air outlet. The air outlet assembly located at the side air outlet 81 can guide the cold air obliquely upward, increase the flow capacity of the cold air attached to the roof, increase the air supply distance of the cold air, and improve the effect of waterfall cooling.

[0060] Specifically, the ducted air conditioner has a first working state in which the side air outlet 81 is used as the return air outlet and the downwind air outlet 82 is used as the outlet. The ducted air conditioner also has a second working state in which the side air outlet 81 is used as the outlet and the downwind air outlet 82 is used as the return air outlet.

[0061] When the duct air conditioner is in the first working state, the air guide structure 2 is in the second state, and the filtering structure 3 is in the filtering state. At this time, the air guide structure 2 opens the air outlet, and the gas enters through the side air outlet 81. The filtering structure 3 can filter the gas to ensure the reliable operation of the duct air conditioner. The gas flowing into the duct air conditioner is discharged through the lower air outlet 82 after heat exchange, completing the gas heat exchange process. When the duct air conditioner is in the first working state, the duct air conditioner performs heating;

[0062] When the duct unit is in the second working state, the air guide structure 2 is in the second state, and the filtering structure 3 is in the avoidance state. At this time, the air guide structure 2 opens the air outlet, and the gas enters from the lower air outlet 82 and flows to the side air outlet 81 after heat exchange. At this time, the filtering structure 3 is in the avoidance state and will not hinder the gas, and the gas will not blow out the dust on the filtering structure 3, thereby ensuring the reliable operation of the duct unit. The gas is blown obliquely upward under the joint guiding action of the air guide structure 2 and the filtering structure 3, increasing the flow capacity of the gas attached to the roof and improving the air supply distance. When the duct unit is in the second working state, the duct unit performs cooling;

[0063] When the duct machine is in a shutdown state, the air guide structure 2 is in the first state, and the filtering structure 3 is in the filtering state. At this time, the air guide structure 2 shields the air outlet and the air outlet frame 1. At the same time, the air guide structure 2 constitutes part of the side wall of the duct machine, preventing users from directly observing the internal structure of the duct machine through the air outlet, thereby improving the appearance of the duct machine.

[0064] When the air-guiding structure 2 is in the second state, the angle ε between the guide surface of the air-guiding structure 2 and the horizontal plane is in the range of 10°≤ε≤40°. The inclination angle of the guide surface can reliably guide the airflow, especially when the side air outlet where the air-guiding structure 2 is located is discharging air, the airflow flows from the air outlet frame 1 to the air-guiding structure 2, and flows obliquely upward under the guiding action of the guide surface, which can promote the airflow to flow along the top of the room, thereby increasing the air supply distance and the waterfall cooling effect in the cooling mode. The air-guiding structure 2 includes an air guide plate, and the area of ​​the air guide plate is the same as that of the air outlet frame 1. At this time, it can be ensured that the air guide plate perfectly shields the air outlet frame 1, thereby improving the appearance of the air outlet assembly. The side of the air guide plate facing the filter structure 3 constitutes the guide surface.

[0065] The filter structure 3 is provided with filter support ribs 31, which are arranged along the length direction of the air guide structure 2, and the angle α between the plane where the filter support ribs 31 are located and the horizontal plane is in the range of 0°<α≤45°. The filter support ribs 31 are used to strengthen the structural strength of the filter structure 3, ensuring that the filter structure 3 can reliably switch between the filtering state and the avoidance state. At the same time, when the filter structure 3 is in the filtering state, the angle α can also further guide the airflow passing through the filter structure 3 on the basis of the guiding effect of the air guide structure 2, thereby facilitating the flow of gas into the interior of the air duct machine. Preferably, the plane where the filter support ribs 31 are located is parallel to the guide surface.

[0066] The filter structure 3 includes a filter frame and a filter screen. The filter screen is slidably mounted on the filter frame, and the filter frame is detachably mounted on the air outlet frame 1. The left and right ends of the filter support ribs 31 are mounted on the filter frame.

[0067] The vent frame 1 is provided with vent support ribs 13, which are arranged along the length direction of the air guide structure, and the angle β between the plane where the vent support ribs 13 are located and the horizontal plane is in the range of 0°<β≤45°. The vent support ribs 13 are used to strengthen the structural strength of the vent frame 1, ensuring the structural strength of the vent frame 1. At the same time, when the filter structure 3 is in the filtering state, the angle β can also further guide the airflow passing through the vent frame 1 based on the guiding effect of the air guide structure 2 and the guiding effect of the filtering support ribs 31 of the filter structure 3, thereby facilitating the flow of gas into the interior of the air duct unit. When the filter structure 3 is in the avoidance state, when the side air vent is discharging air, the vent support ribs 13 can also guide the gas for the first time, prompting the airflow to flow obliquely upward. Then, under the guiding effect of the guide structure 2, the airflow is promoted to flow close to the top of the room, thereby improving the air supply distance and the waterfall cooling effect in the cooling mode. Preferably, the plane where the tuyere support ribs 13 are located is parallel to the guide surface.

[0068] The vent frame 1 is provided with vent support ribs 13, which are arranged along the length of the air guide structure 2. The angle β between the plane on which the vent support ribs 13 are located and the horizontal plane is related to the angle α such that β≤α. When the side vent where the vent assembly is located serves as an air inlet, the filter structure 3 is in a filtering state, and the airflow passes through the filter support ribs 31 and the vent support ribs 13 in sequence. That is, at this time, the filter support ribs 31 first guide the airflow once, and the vent support ribs 13 guide it twice. When the angle β is less than the angle α, the airflow is further diverted by the secondary guidance, increasing its ability to flow into the interior of the duct unit, thereby improving the operating efficiency of the duct unit. When the filter structure 3 is in the avoidance state, the side air vent serves as the air outlet, and the air flow can be initially guided diagonally upward under the guiding action of the air vent support ribs 13, and then continue to turn and flow diagonally upward under the guiding action of the guide structure 2, promoting the air flow to flow along the top of the room, thereby improving the air supply distance and the waterfall cooling effect in the cooling mode.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
