Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air outlet assembly, a duct air conditioner, and an air conditioner. Background Technology

[0002] In existing ducted air conditioners, the outlet of the air vent component is narrower than the outlet of the fan. This is mainly to improve the aesthetics of the air vent component and increase the air delivery speed, resulting in a larger air delivery area and a longer delivery distance. However, because the fan outlet is much wider than the air delivery outlet of the air vent component, some of the airflow from the fan outlet will blow directly towards the air delivery outlet of the air vent component, while the rest will blow directly towards the inner wall of the air vent component. This latter part of the airflow cannot flow directly to the air delivery outlet and will be deflected within the air vent component, creating turbulence. This results in a significant loss of airflow, causing reduced air volume and increased noise in the ducted air conditioner, which seriously affects the user experience. Utility Model Content

[0003] To address the technical problem of inconsistent air outlet and air inlet dimensions of existing fan components affecting user experience, a duct unit and air conditioner are provided that utilize a flow guiding structure to direct airflow to a second connecting port to avoid turbulence, thereby increasing air volume and reducing noise.

[0004] An air vent assembly is disposed at the air vent of a ducted air conditioner, the air vent assembly comprising:

[0005] A housing having a first side and a second side, wherein a first communication port is provided on the first side and a second communication port is provided on the second side;

[0006] The first connection port is connected to the air vent, and the flow area of ​​the second connection port is smaller than the flow area of ​​the first connection port;

[0007] A flow guiding structure is disposed inside the housing and located on one side of the second communication port, the flow guiding structure enabling airflow to flow towards the second communication port.

[0008] The flow guiding structure includes a first filter structure, which is disposed inside the housing. Along the direction close to the second connection port, the distance from the first filter structure to the plane where the first connection port is located gradually decreases.

[0009] The first filter structure has opposing first and second edges, the first edge being located between the second edge and the second communication port, and the first edge having a gap with the adjacent housing.

[0010] The air vent assembly also includes a mounting plate, which is disposed at the spacing. The first edge is disposed on the housing via the mounting plate, and the mounting plate is provided with through holes.

[0011] The air vent assembly further includes a second filter structure, which is disposed at the first connection port, and the filtration accuracy of the second filter structure is less than that of the first filter structure.

[0012] The duct air conditioner includes a fan, the air outlet of the fan is located at the first connecting port, and the flow area of ​​the air outlet is smaller than the flow area of ​​the first connecting port. The second filter structure is provided with a clearance area, and the air outlet is directly connected to the inside of the housing through the clearance area.

[0013] A protective structure is provided in the avoidance area.

[0014] A ducted air conditioner includes the aforementioned air outlet assembly.

[0015] The duct unit has a downdraft outlet and a side outlet, and the outlet assembly is located at the downdraft outlet and / or the side outlet.

[0016] The ducted air conditioner has a cooling mode and a heating mode. When the ducted air conditioner is in the cooling mode, the downvent serves as the return air vent and the side vent serves as the air outlet. When the ducted air conditioner is in the heating mode, the downvent serves as the air outlet and the side vent serves as the return air vent.

[0017] The duct unit includes at least two fans, all of which are arranged side by side along the length of the first connecting port, and the first connecting port is connected to the air outlets of all the fans.

[0018] An air conditioner comprising the aforementioned air outlet assembly or the aforementioned duct unit.

[0019] The air outlet assembly, duct air conditioner, and air conditioner provided by this utility model utilize a flow guiding structure to guide the airflow, enabling the airflow to flow towards the second connecting port. This avoids turbulence within the housing that could affect airflow volume and generate noise. All airflow delivered by the fan can flow smoothly to the second connecting port, thereby ensuring the airflow volume of the duct air conditioner and reducing its noise. Simultaneously, the airflow entering through the second connecting port can also conform to the flow guiding structure, allowing the airflow to flow evenly to the first connecting port. This results in uniform and reliable air intake for the duct air conditioner, thereby improving the user experience. Attached Figure Description

[0034] In existing ducted air conditioners, the outlet of the air vent component is narrower than the outlet of the fan. This is mainly to improve the aesthetics of the air vent component and increase the air delivery speed, resulting in a larger air delivery area and a longer delivery distance. However, because the fan outlet is much wider than the air delivery outlet of the air vent component, some of the airflow from the fan outlet will blow directly towards the air delivery outlet of the air vent component, while the rest will blow directly towards the inner wall of the air vent component. This latter part of the airflow cannot flow directly to the air delivery outlet and will be deflected within the air vent component, creating turbulence. This results in a significant loss of airflow, causing reduced air volume and increased noise in the ducted air conditioner, which seriously affects the user experience.

[0035] Therefore, this application provides a method such as Figures 1 to 7The air vent assembly shown is disposed at the air vent of the ducted air conditioner 1. The air vent assembly includes: a housing 2, having a first side and a second side; a first connecting port 31 is provided on the first side, and a second connecting port 32 is provided on the second side; the first connecting port 31 communicates with the air vent, and the flow area of ​​the second connecting port 32 is smaller than the flow area of ​​the first connecting port 31; and a flow guiding structure 4, disposed within the housing 2 and located on one side of the second connecting port 32, enabling airflow to flow towards the second connecting port 32. To ensure smooth airflow between the air vent and the air vent assembly, the flow area of ​​the first connecting port 31 is greater than or equal to the flow area of ​​the air vent. Preferably, the flow area of ​​the first connecting port 31 is equal to the flow area of ​​the air vent, which facilitates the installation of the air vent assembly and ensures reliable airflow in the ducted air conditioner 1. The airflow is guided by the flow guide structure 4, allowing the airflow to flow towards the second connection port 32. This avoids turbulence in the airflow within the housing 2, which would affect the air volume and generate noise. All the airflow delivered by the fan can flow smoothly to the second connection port 32, thereby ensuring the air volume delivered by the duct unit 1 and reducing the noise of the duct unit 1. At the same time, the airflow entering through the second connection port 32 can also flow in close contact with the flow guide structure 4, so that the airflow can flow evenly to the first connection port 31. This makes the air intake of the duct unit 1 uniform and reliable, thereby improving the user experience. When the air outlet is used as an air outlet, the airflow from the part of the air outlet directly opposite the second connecting port 32 can be directly blown towards the second connecting port 32, while the airflow from the part not opposite the second connecting port 32 can flow through the guide structure 4 and flow towards the second connecting port 32 along the guide structure 4. Finally, all the airflow flows out through the second connecting port 32, avoiding the problem of turbulence in the airflow within the housing 2, ensuring the airflow volume of the ducted air conditioner 1, and reducing the noise of the ducted air conditioner 1. When the air outlet is used as an air inlet, part of the airflow in the second connecting port 32 will adhere to the surface of the guide structure 4 and flow, so that the airflow in each area of ​​the first connecting port 31 is basically the same. This avoids the problem of unreliable return air of the fan in the ducted air conditioner 1 caused by the airflow of the second connecting port 32 only being delivered to its corresponding part of the first connecting port 31 in the prior art, ensuring the return air capability of the ducted air conditioner 1, and thus ensuring the airflow and heat exchange efficiency of the ducted air conditioner 1.

[0036] In one embodiment, the airflow guiding structure 4 includes a first filter structure disposed inside the housing 2. Along the direction close to the second connecting port 32, the distance from the first filter structure to the plane where the first connecting port 31 is located gradually decreases. The airflow is guided by the resistance of the first filter structure to the airflow. When the air outlet delivers air, most of the airflow blowing towards the first filter structure will flow towards the second connecting port 32 under the guidance of the first filter structure. A small portion of the airflow will pass through the first filter structure. This small portion of the airflow will consume energy and reduce its wind speed after passing through the first filter structure, which can also avoid the problem of noise caused by impacting the housing 2. At the same time, this small portion of the airflow can continue to flow to the second connecting port 32 to supplement the airflow at the edge of the second connecting port 32, ensuring the uniformity of air delivery at the second connecting port 32 and improving the air delivery effect of the air outlet assembly.

[0037] In this case, the flow area of ​​the fan outlet of the ducted air conditioner 1 is smaller than that of the first connecting port 31. In particular, the length of the fan outlet is smaller than that of the first connecting port 31. When the airflow delivered by the fan comes into contact with the guide structure 4, it will not only flow along the inclined direction of the guide structure 4 to the second connecting port 32, but also flow along the length direction of the first connecting port 31 due to the existence of flow resistance. This can further improve the uniformity of the airflow to the second connecting port 32 and further improve the air delivery effect of the ducted air conditioner 1.

[0038] The first filter structure has a first edge and a second edge, with the first edge located between the second edge and the second connecting port 32. A gap exists between the first edge and the adjacent housing 2. That is, the distance from the first edge to the plane of the first connecting port 31 is greater than the distance from the second edge to the plane of the first connecting port 31. Airflow can flow from the second edge to the first edge. Airflow passing through the first filter structure can be delivered to the second connecting port 32 through the gap, further increasing the airflow replenishment at the edge of the second connecting port 32, ensuring the uniformity of airflow at the second connecting port 32, and improving the airflow effect of the air outlet assembly. Simultaneously, when the air outlet serves as a return air outlet, some airflow from the second connecting port 32 can flow through the gap to the side of the first filter structure away from the first connecting port 31, and after passing through the first filter structure, flow back to the first connecting port 31, adjusting the uniformity of airflow at the first connecting port 31. This ensures the reliability of the fan intake of the ducted air conditioner 1, improving the reliability and heat exchange efficiency of the ducted air conditioner 1.

[0039] The air outlet assembly also includes a mounting plate 5, which is disposed at the spacing. The first edge is mounted on the housing 2 via the mounting plate 5, and the mounting plate 5 has a through hole 51. The mounting plate 5 is used to install the first filter structure, and the through hole 51 on the mounting plate 5 also ensures that airflow passes through the spacing, thereby ensuring the uniformity of airflow at the second connecting port 32 when the air outlet is used as an air supply outlet, and the uniformity of airflow at the first connecting port 31 when the air outlet is used as a return air outlet.

[0040] Since the air vent can be used as a return air vent, the air vent assembly also includes a second filter structure 6. The second filter structure 6 is disposed at the first connecting port 31. The second filter structure 6 filters the airflow that is about to flow into the duct unit 1, ensuring the reliability of the duct unit 1. The filtration accuracy of the second filter structure 6 is less than that of the first filter structure, so that the second filter structure 6 can ensure that the airflow is filtered while generating higher airflow resistance by utilizing the high filtration accuracy of the first filter structure, thereby improving the airflow guiding effect.

[0041] The ducted air conditioner 1 includes a fan 11, the air outlet of which is located at the first connecting port 31. Since the air outlet can serve as both a return air inlet and a supply air inlet, the first connecting port 31 needs to simultaneously meet the requirements for both return and supply air. Therefore, the flow area of ​​the air outlet is smaller than that of the first connecting port 31. When the air outlet supplies air, the airflow from the fan 11 can directly enter the housing 2 through the corresponding part of the first connecting port 31. When the fan 11 supplies return air and the air outlet is closed, other areas of the first connecting port 31 can supply air into the ducted air conditioner 1. For this purpose, the second filter structure 6 is provided with a clearance area 61. The air outlet is directly connected to the interior of the housing 2 through the clearance area 61. The clearance area 61 does not filter the air outlet from the fan 11, while other areas of the second filter structure 6 can filter the gas to ensure the cleanliness of the air entering the ducted air conditioner 1 and ensure the reliable operation of the ducted air conditioner 1.

[0042] A protective structure 7 is provided at the avoidance area 61 to prevent the internal structure of the fan 11 from being directly exposed, and to prevent the user's hands or other objects from accidentally contacting the fan blades of the fan 11, thus ensuring user safety. Preferably, the protective structure 7 is a wire mesh, which improves user safety while minimizing wind resistance.

[0043] A ducted air conditioner 1 includes the aforementioned air outlet assembly.

[0044] The duct unit 1 has a downdraft outlet and a side outlet, and the outlet assembly is located at the downdraft outlet and / or the side outlet.

[0045] The ducted air conditioner 1 has a cooling mode and a heating mode. When the ducted air conditioner 1 is in the cooling mode, the lower air outlet serves as a return air outlet, and the side air outlet serves as an air outlet. When the ducted air conditioner 1 is in the heating mode, the lower air outlet serves as an air outlet, and the side air outlet serves as a return air outlet. The lower air outlet is located on the bottom wall of the ducted air conditioner 1's housing, and the side air outlet is located on the side wall of the ducted air conditioner 1's housing. When the ducted air conditioner 1 is in the cooling mode, it achieves bottom return air and side air outlet, realizing horizontal blowing of cold air and avoiding the discomfort caused by direct blowing of cold air. When the ducted air conditioner 1 is in the heating mode, it achieves side return air and bottom air outlet, realizing downward blowing of hot air and improving the heating effect.

[0046] The ducted air conditioner 1 includes at least two fans 11, all of which are arranged side by side along the length of the first connecting port 31. The first connecting port 31 is connected to the air outlets of all the fans 11. The avoidance areas 61 on the second filter structure 6 correspond one-to-one with the fans 11. The first connecting port 31 simultaneously satisfies the return air and supply air of all the fans 11. At the same time, when the air outlet is used as the supply air outlet, the airflow of the fans 11 can flow directly through the corresponding avoidance areas 61 without filtration, thus preventing dust on the second filter structure 6 from being blown back into the room, ensuring the cleanliness of the room and improving the user experience.

[0047] An air conditioner includes the aforementioned air outlet assembly or the aforementioned duct unit 1.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
