[0047] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] The prior art generally controls the fan to reverse to achieve reverse air discharge from the fan, so that the indoor unit can simultaneously achieve the purpose of horizontal and vertical air supply. 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 prior art cannot meet the air flow direction requirements of the indoor unit. In particular, when there is an air outlet of the filter structure as an 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 arranged; an air guide structure 2, which is rotatably arranged 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 arranged 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 using 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 jointly form a dust collecting space 10. The collision generated by the 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. The filter structure 3 can also be cleaned to prepare for the next filtering. When the air outlet is used as an air inlet, the filter structure 3 can cover the air outlet for filtering to achieve 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 to prevent 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 also has a dust collecting structure, which is detachably arranged 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, the impurities on the filter structure 3 will enter the dust collecting space 10 and eventually accumulate on the dust collecting structure. The user can clean the impurities by disassembling the dust collecting structure, thereby avoiding the impurities from being carried by the airflow to the filter structure 3 again, 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 includes a dust collecting box, and an installation slot is provided on the air outlet frame 1. The dust collecting box is detachably arranged in the installation slot, and the opening of the dust collecting box is connected to the dust collecting space 10. The 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 from 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 arranged, and the lower part of the air guide structure 2 is rotatably connected to the first rotating support structure 11. The lower part of the filtering structure 3 is rotatably connected to the second rotating support structure 12. When the air guide structure 2 is switched from the first state to the second state, the air guide structure 2 and the filtering structure 3 are both rotated around the lower crossbeam, so that the air guide structure 2 in the second state and the filtering structure 3 in the avoidance state can cooperate with each other to blow the air flow blown out of the air outlet obliquely upward. When cooling, the cold air can be blown out through the air outlet and flow obliquely upward under the guiding effect of the air guide structure 2 and the filtering structure 3, thereby increasing the air supply distance of the cold air, and reducing the problem of the cold air flowing downward quickly due to the influence of gravity, thereby improving the effect of waterfall cooling and the user's experience. The first rotating support structure 11 and the second rotating support structure 12 can make the air guide structure 2 and the filtering structure 3 rotate separately, ensuring the reliable operation of the air guide structure 2 and the filtering structure 3.

[0051] There is a clearance distance between the first rotating support structure 11 and the second rotating support structure 12. The clearance distance is used to avoid interference between the air guide structure 2 and the filter structure 3, thereby ensuring the working reliability of the air outlet assembly. At the same time, the clearance distance can also facilitate the arrangement of the dust collecting space 10, increase the size of the dust collecting space 10, and facilitate cleaning of the dust collecting space 10.

[0052] As an embodiment, the lower part of the air guide 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 guide structure 2, so that when the air guide structure 2 rotates, the rotation radius of the lower edge of the air guide structure 2 is larger than the distance between the lower edge of the air guide structure 2 and the filter structure 3, and also larger than the distance between the lower edge of the air guide structure 2 and the air outlet frame 1, thereby avoiding the filter structure 3 and the air outlet frame 1 to ensure the reliability of the air guide structure 2, and the support member 4 located in the middle of the air guide structure 2 can also reliably support the air guide structure 2 to prevent the air guide structure 2 from sagging due to excessive length, thereby improving the structural reliability of the air guide 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 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 and the filter structure 3 and the tuyere frame 1 cannot be reliably guaranteed. Only when 0≤L1≤25mm can the rotation of the air guide structure 2 be guaranteed to be reliable 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 spacing 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 spacing L2 is too large, the thickness of the tuyere frame 1 will be larger, affecting the overall volume of the tuyere assembly. When the spacing L2 is too small, the avoidance reliability between the air guide structure 2 and the filter structure 3 and the tuyere frame 1 cannot be reliably guaranteed. Only when 5mm≤L2≤60mm can the rotation of the air guide structure 2 be guaranteed to be reliable 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 driving structure, which is disposed on the tuyere frame 1 and is in driving connection with the air guide structure 2; and / or, the driving structure is in driving connection with the filtering structure 3. The driving structure can drive the air guide structure 2 and / or the filtering structure 3 to rotate, thereby realizing the switching of the air guide structure 2 between the first state and the second state and the switching of the filtering structure 3 between the filtering state and the avoidance state.

[0056] Specifically, the driving 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, which ensure that the air guide structure 2 and the filter structure 3 work separately and ensure that the air guide structure 2 and the filter structure 3 work 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 member. The transmission member is used to push or pull the upper part of the air guide structure 2 to ensure reliable movement of the air guide structure 2.

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

[0059] The air outlet assembly is applied to the duct machine, which 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 realize waterfall cooling. At this time, the side air outlet 81 is used for air discharge. 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 duct machine has a first working state in which the side air outlet 81 is used as the return air outlet and the lower air outlet 82 is used as the outlet, and the duct machine also has a second working state in which the side air outlet 81 is used as the outlet and the lower air outlet 82 is used as the return air outlet;

[0061] When the duct machine 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 port, and the gas enters from the side air port 81. The filtering structure 3 can filter the gas to ensure the reliable operation of the duct machine. The gas flowing into the duct machine is discharged through the lower air port 82 after heat exchange, completing the heat exchange process of the gas. When the duct machine is in the first working state, the duct machine performs heating;

[0062] When the duct machine is in the second working state, the air guide structure 2 is in the second state, and the filter 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 filter structure 3 is in the avoidance state and will not hinder the gas, and the gas will not blow out the dust on the filter structure 3, so as to ensure the reliable operation of the duct machine. The gas is blown obliquely upward under the joint guiding effect of the air guide structure 2 and the filter structure 3, which increases the flow capacity of the gas attached to the roof and improves the air supply distance. When the duct machine is in the second working state, the duct machine performs cooling;

[0063] When the duct air conditioner 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 air conditioner, thereby preventing the user from directly observing the internal structure of the duct air conditioner through the air outlet, thereby improving the appearance of the duct air conditioner.

[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 effect 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 effect of waterfall cooling 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, so as to facilitate 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 arranged on the filter frame, and the filter frame is detachably arranged on the air outlet frame 1. The left and right ends of the filter support rib 31 are arranged 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 range of the angle β between the plane where the vent support ribs 13 are located and the horizontal plane is 0°<β≤45°. The vent support ribs 13 are used to strengthen the structural strength of the vent frame 1 to ensure 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 on the basis of the guiding effect of the air guide structure 2 and the guiding effect of the filtering support ribs 31 of the filtering structure 3, so as to facilitate the flow of gas to the inside of the air duct machine. When the filtering structure 3 is in the avoidance state, when the side 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, and then under the guiding effect of the guiding structure 2, promote the airflow to flow on the top of the room, thereby improving the air supply distance and the effect of waterfall cooling in the cooling mode. Preferably, the plane where the tuyere supporting 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 direction of the air guide structure 2, and the angle β between the plane where the vent support ribs 13 are located and the horizontal plane and the angle α are in a relationship of β≤α. When the side vent where the vent assembly is located is used 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, and the vent support ribs 13 guide the airflow for the second time, and when the angle β is less than the angle α, then under the action of the secondary guide, the airflow is further turned to increase the ability to flow into the inside of the duct machine, thereby improving the working efficiency of the duct machine. When the filtering structure 3 is in the avoidance state, the side air vent serves as the air outlet, and the airflow can be initially guided diagonally upward under the guiding effect of the air vent support ribs 13, and then continue to turn and flow diagonally upward under the guiding effect of the guiding structure 2, promoting 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.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
