In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0033] 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.

[0034] In the air duct machine of the prior art, the air outlet of its air outlet component is smaller than the air outlet width of the fan, mainly to improve the aesthetics of the air outlet component and to increase the air supply speed of the air outlet, so that the air supply area is larger and the air is supplied farther; however, since the width of the air outlet of the fan is much larger than the air supply width of the air outlet component, part of the air flow delivered by the air outlet of the fan will be directly blown to the air supply port of the air outlet component, and another part of the air flow will be directly blown to the inner wall of the air outlet component. This part of the air flow cannot flow directly to the air supply port and will be deflected in the air outlet component to generate turbulence, thereby generating a large air volume loss, resulting in a reduced air volume and increased noise for the air duct machine, seriously affecting the user experience.

[0035] To this end, the present application provides a Figures 1 to 7The tuyere assembly shown is arranged at the tuyere of the air duct machine 1, and the tuyere assembly comprises: a shell 2, the shell 2 has a first side surface and a second side surface, a first connecting port 31 is arranged on the first side surface, and a second connecting port 32 is arranged on the second side surface; the first connecting port 31 is connected with the tuyere, and the flow area of ​​the second connecting port 32 is smaller than the flow area of ​​the first connecting port 31; a guide structure 4, the guide structure 4 is arranged in the shell 2, and the guide structure 4 is located on one side of the second connecting port 32, and the guide structure 4 can make the air flow flow in the direction of the second connecting port 32. In order to ensure that the air flow can flow smoothly between the tuyere and the tuyere assembly, the flow area of ​​the first connecting port 31 is greater than or equal to the flow area of ​​the tuyere, and preferably, the flow area of ​​the first connecting port 31 is equal to the flow area of ​​the tuyere, which is convenient for the installation of the tuyere assembly and can ensure the reliable flow of the air flow of the air duct machine 1. The airflow is guided by the guide structure 4 so that it can flow to the second connecting port 32, thereby preventing the airflow from generating turbulence in the shell 2 and affecting the air volume and generating noise. All airflows delivered by the fan can flow smoothly to the second connecting port 32, thereby ensuring the air volume of the duct machine 1 and reducing the noise of the duct machine 1. At the same time, the airflow entering from the second connecting port 32 can also flow in the guide structure 4, so that the airflow can flow evenly to the first connecting port 31, making the air intake of the duct machine 1 even and reliable, thereby improving the user experience. When the air outlet is used as an air outlet to supply air, the air flow delivered by the part of the air outlet that is directly opposite to the second connecting port 32 can be directly blown to the second connecting port 32, and the air flow delivered by the part that is not opposite to the second connecting port 32 can flow through the guide structure 4 and flow to the second connecting port 32 along the guiding effect of the guide structure 4. Finally, all the air flows out through the second connecting port 32, avoiding the problem of air turbulence in the shell 2, ensuring the air supply volume of the duct machine 1, and reducing the noise of the duct machine 1. When the air outlet is used as an air inlet, part of the air flow of the second connecting port 32 will flow along the surface of the guide structure 4, so that the air flow rate at each area of ​​the first connecting port 31 is basically the same, avoiding the problem in the prior art that the air flow of the second connecting port 32 is only delivered to the corresponding part of the first connecting port 31, causing the fan in the duct machine 1 to have unreliable return air, ensuring the return air capacity of the duct machine 1, and then ensuring the air volume and heat exchange efficiency of the duct machine 1.

[0036] As an embodiment, the guide structure 4 includes a first filtering structure, which is arranged in the shell 2. Along the direction close to the second connecting port 32, the distance from the first filtering structure to the plane where the first connecting port 31 is located gradually decreases. The airflow is guided by the resistance of the first filtering structure to the airflow. When the air outlet is supplying air, most of the airflow blowing to the first filtering structure will flow to the second connecting port 32 under the guiding action of the first filtering structure, and a small amount of airflow will flow through the first filtering structure. After passing through the first filtering structure, this small amount of airflow will consume energy and reduce the wind speed, which can also avoid the problem of impacting the shell 2 to generate noise. At the same time, this small amount of airflow can continue to flow to the second connecting port 32 to supplement the air flow at the edge of the second connecting port 32, thereby ensuring the uniformity of air supply from the second connecting port 32 and improving the air supply effect of the air outlet component.

[0037] Among them, the flow area of ​​the fan outlet of the duct machine 1 is smaller than the flow area of ​​the first connecting port 31, and especially the length of the fan outlet is smaller than the length of the first connecting port 31. When the airflow delivered by the fan contacts the guide structure 4, it will not only flow toward the second connecting port 32 along the inclined direction of the guide structure 4, but also flow toward the length direction of the first connecting port 31 due to the existence of flow resistance, thereby further improving the uniformity of the airflow flowing to the second connecting port 32 and further improving the air supply effect of the duct machine 1.

[0038] The first filter structure has a first edge and a second edge relative to each other, the first edge is located between the second edge and the second connecting port 32, and there is a spacing between the first edge and the adjacent housing 2. That is, the distance from the first edge to the plane where the first connecting port 31 is located is greater than the distance from the second edge to the plane where the first connecting port 31 is located, and the airflow can be transported from the second edge to the first, and the airflow passing through the first filter structure can be transported to the second connecting port 32 through the spacing, further improving the supplement of the airflow at the edge position of the second connecting port 32, ensuring the uniformity of the air supply of the second connecting port 32, and improving the air supply effect of the air outlet assembly. At the same time, when the air outlet is used as a return air outlet, part of the airflow of the second connecting port 32 can flow to the side of the first filter structure away from the first connecting port 31 through the spacing, and flow to the first connecting port 31 after passing through the first filter structure, and adjust the uniformity of the airflow of the first connecting port 31, thereby ensuring the air intake reliability of the fan of the air duct machine 1, and improving the reliability and heat exchange efficiency of the air duct machine 1.

[0039] The tuyere assembly further includes a mounting plate 5, the mounting plate 5 is arranged at the spacing, the first edge is arranged on the housing 2 through the mounting plate 5, and the mounting plate 5 is provided with a through hole 51. The mounting plate 5 is used to realize the installation of the first filtering structure, and the through hole 51 on the mounting plate 5 is also used to ensure that the airflow flows through the spacing, thereby ensuring the uniformity of the airflow of the second connecting port 32 when the tuyere is used as an air supply port and the uniformity of the airflow of the first connecting port 31 when the tuyere is used as an air return port.

[0040] Since the air outlet can be used as a return air outlet, the air outlet assembly also includes a second filtering structure 6, which is arranged at the first connecting port 31. The second filtering structure 6 is used to filter the airflow that is about to flow into the duct machine 1 to ensure the reliability of the duct machine 1. The filtering accuracy of the second filtering structure 6 is lower than the filtering accuracy of the first filtering structure, so that the second filtering structure 6 can ensure that the airflow is filtered while using the high filtering accuracy of the first filtering structure to generate a higher airflow resistance, thereby improving the airflow guidance effect.

[0041] The duct machine 1 includes a fan 11, and the air outlet of the fan 11 is located at the first connecting port 31. Since the air outlet can be used as a return air outlet or as an air inlet, the first connecting port 31 needs to meet the return air and air supply requirements at the same time. Therefore, the flow area of ​​the air outlet is smaller than the flow area of ​​the first connecting port 31. When the air outlet is supplying air, the airflow of the fan 11 can directly enter the shell 2 through the corresponding part of the first connecting port 31, and when the fan 11 is returning air and this air outlet is closed, other areas of the first connecting port 31 can supply air to the duct machine 1. For this reason, an avoidance area 61 is provided on the second filtering structure 6, and the air outlet is directly connected to the inside of the shell 2 through the avoidance area 61. The air outlet of the fan 11 is not filtered by the avoidance area 61, while other areas of the second filtering structure 6 can filter the gas to ensure the cleanliness of the air inlet of the duct machine 1 and ensure the reliable operation of the duct machine 1.

[0042] The avoidance area 61 is provided with a protective structure 7, which is used to prevent the internal structure of the fan 11 from being directly exposed, and to prevent the user's hands or other objects from contacting the fan blades of the fan 11 due to misoperation, thereby ensuring the user's safety. Preferably, the protective structure 7 is a steel mesh, which improves the user's safety while minimizing wind resistance.

[0043] A duct machine 1 comprises the above-mentioned tuyere assembly.

[0044] The air duct machine 1 has a downwind outlet and a side outlet, and the outlet assembly is arranged at the downwind outlet and / or the side outlet.

[0045] The duct machine 1 has a cooling mode and a heating mode. When the duct machine 1 is in the cooling mode, the lower air outlet serves as the return air outlet and the side air outlet serves as the outlet. When the duct machine 1 is in the heating mode, the lower air outlet serves as the outlet and the side air outlet serves as the return air outlet. The lower air outlet is arranged on the bottom wall of the shell of the duct machine 1, and the side air outlet is arranged on the side wall of the shell of the duct machine 1. When the duct machine 1 is in the cooling mode, the duct machine 1 realizes the return air from the bottom and the side air outlet, realizes the horizontal blowing of the cold air, and avoids the discomfort caused by the direct blowing of the cold air. When the duct machine 1 is in the heating mode, it realizes the side return air and the bottom air outlet, realizes the downward blowing of the hot air, and improves the heating effect.

[0046] The duct machine 1 includes at least two fans 11, all of which are arranged in parallel along the length direction of the first connecting port 31, and the first connecting port 31 is connected to the air outlets of all the fans 11. The avoidance area 61 on the second filtering structure 6 corresponds to the fan 11 one by one, and the first connecting port 31 simultaneously meets the return air and supply air needs of all fans 11. At the same time, when the air outlet is used as the supply air outlet, the airflow of the fan 11 can flow directly through the corresponding avoidance area 61 without filtering, thereby preventing the dust on the second filtering structure 6 from being blown back into the room, ensuring the cleanliness of the room, and improving the user experience.

[0047] An air conditioner comprises the above-mentioned air outlet assembly or the above-mentioned air duct unit 1.

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.
