Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to an air outlet component and an air duct unit. Background Technology

[0002] The difference in density between cold and hot air causes cold air to sink and hot air to rise. Traditional air conditioners use a single vent to supply air and guide the airflow through a deflector to adjust the direction of the airflow. However, this forced airflow adjustment results in poor regulation. In addition, traditional vent components return air through a single return air vent, and their air ducts only serve one function: supplying or returning air. Deflectors are only installed at the air outlet.

[0003] Traditional ducted air conditioners have a bottom air vent and a side air vent. In cooling mode, the airflow returns from the bottom and exits from the side, while in heating mode, the airflow returns from the side and exits from the bottom. The two air vents supply or return air depending on the operating mode. For example, in cooling mode, the bottom air vent is the return air vent, but in heating mode, the bottom air vent is the air outlet. Therefore, the bottom air vent is equipped with an air guide plate, that is, the return air vent of the ducted air conditioner is equipped with an air guide plate.

[0004] When ducted air conditioners have high airflow requirements, they increase the fan speed to increase the return air volume and ensure the output airflow. However, as the airflow increases, the noise level of the entire unit also increases, and the vibration of the entire casing increases. At the same time, when the airflow requirement of ducted air conditioners is low, the air guide plate at the return air inlet of traditional ducted air conditioners needs to be kept open at all times to ensure smooth airflow, but the air duct is prone to dust accumulation and affects the appearance.

[0005] There is currently no effective solution to the problems of excessive noise in ducted air conditioners or dust accumulation in normally open return air vents. Utility Model Content

[0006] This utility model provides an air outlet component and a duct air conditioner, which at least solves the problems of excessive noise in existing duct air conditioners or the easy accumulation of dust in the normally open air duct of the return air outlet guide plate.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present utility model, an air outlet component is provided, applied to the return air outlet of a ducted air conditioner. The air outlet component includes: an air guide plate communicating with the return air channel of the ducted air conditioner, the air channel in which the air guide plate is located is a first return air channel; an auxiliary return air outlet communicating with the return air channel of the ducted air conditioner; and a return air panel covering the auxiliary return air outlet, the return air panel having a through-hole structure, the air channel in which the auxiliary return air outlet and the return air panel are located is a second return air channel; the ducted air conditioner uses the first return air channel and the second return air channel for return air, or uses the second return air channel for return air.

[0008] Furthermore, it also includes: a driving structure connected to the return air panel, for driving the return air panel to slide above the auxiliary return air inlet and the air guide plate to cover the auxiliary return air inlet or cover the auxiliary return air inlet and the air guide plate.

[0009] Furthermore, the area of ​​the return air panel is greater than the sum of the opening areas of the auxiliary return air vent and the air guide plate, and the return air panel always overlaps with the auxiliary return air vent during the sliding process to cover the auxiliary return air vent.

[0010] Furthermore, the auxiliary return air vent includes one or more ventilation openings, and the ventilation openings are provided with reinforcing ribs.

[0011] Furthermore, the second return air duct is always in a conductive state, and the through-hole structures on the return air panel are arranged side by side or staggered, with the axial direction of the through-hole structures being perpendicular or inclined relative to the surface of the return air panel.

[0012] Furthermore, the air guide plate can be opened or closed, wherein when the air guide plate is open, the first return air channel is in a conductive state, and when the air guide plate is closed, the first return air channel is in a closed state; the air guide plate adopts a multi-layer structure, and reinforcing ribs are provided between the multi-layer air guide plates, and the air guide plate forms an angle of 0 to 90° with the return air panel after it is opened.

[0013] According to another aspect of the present invention, a duct air conditioner is provided, the duct air conditioner including the air outlet component as described above.

[0014] This invention provides an air vent component for use in the return air vent of a ducted air conditioner. The air vent component includes a first return air duct with a guide vane and a second return air duct containing a newly added auxiliary return air vent. A return air panel is installed above the auxiliary return air vent. When the ducted air conditioner has a high airflow requirement, the first and second return air ducts can be used for return air. By adding the second return air duct, the return air area is increased, which can reduce the fan speed and thus reduce the noise of the ducted air conditioner. When the ducted air conditioner has a low airflow requirement, the second return air duct can be used for return air. In this case, the first return air duct and the guide vane are in a closed state, preventing dust accumulation in the normally open air ducts of the guide vane, which would affect aesthetics, and also preventing dust accumulation in the second return air duct. Therefore, the air vent component of this invention not only effectively reduces the noise of the ducted air conditioner but also improves its appearance, keeping it clean and aesthetically pleasing.

[0029] The optional embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] In a preferred embodiment of this utility model, an air vent component is provided for use in the return air vent of a ducted air conditioner. The ducted air conditioner has a bottom air vent and a side air vent. In cooling mode, the airflow is bottom return and side exit, and in heating mode, the airflow is side return and bottom exit. The two air vents supply or return air according to the operating mode.

[0032] Figure 1 This diagram illustrates one possible airflow pattern in ducted cooling mode, such as... Figure 1 As shown, in cooling mode, the ducted air conditioner returns air from the bottom vent and exits air from the side vent.

[0033] Figure 2 This diagram illustrates one possible airflow pattern in the heating mode of a duct system, such as... Figure 2 As shown, in heating mode, the ducted air conditioner returns air from the side vent and exits air from the bottom vent.

[0034] Traditional air conditioning units typically do not have air deflectors at the return air vent; they are only installed at the air outlet. However, ducted air conditioners have adjustable air vents—meaning the functions of the return and outlets can be reversed—so the air vent used as a return air vent can also be used for air outlets. Therefore, the return air vent also has an air deflector. As a result, when the airflow demand of the ducted air conditioner is low, the air deflector is always open to ensure smooth airflow, but this also leads to dust accumulation in the duct and affects its appearance.

[0035] For ducted air conditioners with both cooling and heating modes, the air vent component of this invention can be installed at both air outlets, as both outlets may serve as return air inlets. Alternatively, the air vent component can be installed only at the lower air outlet, solving the problems of excessive noise in cooling mode or dust accumulation and aesthetic issues with the normally open return air guide plate. Or, the air vent component can be installed at the side air outlet, solving the problems of excessive noise in heating mode or dust accumulation and aesthetic issues with the normally open return air guide plate.

[0036] Specifically Figure 3 This diagram illustrates one possible structural design for the air vent component, such as... Figure 3 As shown, the air vent component includes:

[0037] The air guide plate 1 is connected to the return air duct of the duct unit, and the air duct where the air guide plate 1 is located is the first return air duct.

[0038] Auxiliary return air vent 3 is connected to the return air duct of the ducted air handling unit; due to Figure 3 This is an external view of the air vent component. The auxiliary return air vent 3 is located at the bottom of the return air panel, therefore, it is not shown in the diagram. Figure 3 As shown in the image;

[0039] The return air panel 2 covers the auxiliary return air inlet 3. The return air panel 2 is provided with a through-hole structure. The air duct where the auxiliary return air inlet 3 and the return air panel 2 are located is the second return air channel. The return air panel 2 is provided with a through-hole structure, which on the one hand does not affect the return air, and on the other hand prevents dust from falling into the second return air channel, so as to achieve the return air while maintaining a clean and beautiful appearance.

[0040] The air outlet component divides the air outlet into two parts, and therefore the return air duct is divided into a first return air duct and a second return air duct. Both the first and second return air ducts are connected to the return air outlet. Ductless air conditioners use the first and second return air ducts for return air to avoid the problem of excessive noise from ductless air conditioners, or they use the second return air duct to avoid the problem of dust accumulation and aesthetic issues caused by the open air duct of the air guide plate.

[0041] In the above embodiments, an air outlet component is provided for use in the return air outlet of a ducted air conditioner. The air outlet component includes a first return air channel with an air guide plate and a second return air channel containing a newly installed auxiliary return air outlet. A return air panel is provided above the auxiliary return air outlet. When the air conditioner's airflow demand is high, the first and second return air channels can be used for return air. By adding the second return air channel, the return air area is increased, which can reduce the fan speed and thus reduce the noise of the ducted air conditioner. When the air conditioner's airflow demand is low, the second return air channel can be used for return air. In this case, the first return air channel and the air guide plate are in a closed state, preventing dust from accumulating in the normally open air duct of the air guide plate and affecting aesthetics, while also preventing dust from accumulating in the second return air channel. Therefore, the air outlet component of this invention can not only effectively reduce the noise of the ducted air conditioner but also improve its appearance, keeping it clean and aesthetically pleasing.

[0042] In a preferred embodiment of this invention, the return air panel 2 is a sliding panel, and therefore further includes a driving structure connected to the return air panel 2 for driving the return air panel 2 to slide over the auxiliary return air inlet 3 and the air guide plate 1, so as to cover the auxiliary return air inlet 3 or cover the auxiliary return air inlet 3 and the air guide plate 1. Setting the return air panel 2 as a sliding panel expands the function of the air outlet component; that is, not only the second return air duct can be covered by the return air panel 2, but both the first and second return air ducts can also be covered by the return air panel 2 simultaneously. When the second return air duct is covered by the return air panel 2, the air guide plate 1 can be opened or closed to achieve different operating modes. When both the first and second return air ducts are covered by the return air panel 2 simultaneously, the air guide plate 1 can also be opened or closed to achieve two other different operating modes.

[0043] For the sliding return air panel 2, the area of ​​the return air panel 2 is larger than the sum of the opening areas of the auxiliary return air inlet 3 and the air guide plate 1, and the return air panel 2 always overlaps with the auxiliary return air inlet 3 during the sliding process, so as to cover the auxiliary return air inlet 3. That is, the return air panel 2 always covers the auxiliary return air inlet 3, or the second return air channel, to ensure that when the air volume demand of the ducted air unit is small and the second return air channel is used for return air, the first return air channel and the air guide plate 1 are in a closed state, to avoid dust accumulation in the normally open air duct of the air guide plate 1, which would affect the aesthetics, and at the same time, to prevent dust accumulation in the second return air channel.

[0044] Preferably, the second return air duct is always in a conductive state, and the auxiliary return air vent 3 includes one or more ventilation openings, which are provided with reinforcing ribs. Figure 4 This diagram illustrates one possible structure of the auxiliary return air vent 3, such as... Figure 4 As shown, the auxiliary return air vent 3 is divided into multiple ventilation openings, and the ventilation openings are equipped with reinforcing ribs to maintain structural stability and ensure smooth return airflow.

[0045] There are multiple ways to set the through-hole structure on the return air panel 2, such as parallel or staggered arrangement. The axis of the through-hole structure is set perpendicular to or inclined to the surface of the return air panel 2 to keep the air duct unobstructed, increase the return air area, and make the return air more uniform and smooth.

[0046] In another optional embodiment of this utility model, the air guide plate 1 can be opened or closed. When the air guide plate 1 is open, the first return air channel is in a conductive state, and when the air guide plate 1 is closed, the first return air channel is in a closed state. The air guide plate 1 adopts a multi-layer structure, and reinforcing ribs are provided between the multi-layer air guide plates 1. When the air guide plate 1 is opened, it forms an angle of 0 to 90° with the return air panel 2. Figure 3 The middle air guide plate 1 is in the closed state. Figure 3 The return air panel 2 is in the open state, that is, the air guide plate 1 is exposed, and the return air panel 2 only covers the second return air duct. Figure 5 This diagram illustrates one possible configuration of the return air panel 2 being closed. Figure 5 The intermediate return air panel 2 covers the auxiliary return air inlet 3 and the air guide plate 1, meaning that both the first and second return air channels are covered by the return air panel 2. The air guide plate 1 can be opened or closed. Figure 6 The diagram shows an optional configuration of the air guide plate 1. Here, the air guide plate 1 is configured as two layers, but more layers can also be configured. When the air is discharged downwards, multiple rib structures perpendicular to the outer surface are provided between the two layers of air guide plates 1. Both layers of air guide plates 1 can guide the airflow.

[0047] The above embodiment provides a sliding panel and its air vent component. The air vent component's guide plate is located in the main airflow return channel, i.e., the first return air channel. The sliding panel is provided with a multi-micro-perforated structure, which, together with the auxiliary return air channel, forms the second airflow return channel. Simultaneously, a drive mechanism is provided on the back of the sliding panel. Driven by a motor, the sliding panel can slide parallel along its width direction, achieving different airflow return methods, while also possessing a high-tech feel and enhancing the user experience.

[0048] Example 2

[0049] In a preferred embodiment 2 of this utility model, a duct air conditioner is provided, wherein the air outlet of the duct air conditioner is provided with the air outlet component as described in embodiment 1 above.

[0050] For ducted air conditioners with both cooling and heating modes, the air vent component of this invention can be installed at both air outlets, as both outlets may serve as return air inlets. Alternatively, the air vent component can be installed only at the lower air outlet, solving the problems of excessive noise in cooling mode or dust accumulation and aesthetic issues with the normally open return air guide plate. Or, the air vent component can be installed at the side air outlet, solving the problems of excessive noise in heating mode or dust accumulation and aesthetic issues with the normally open return air guide plate.

[0051] In the above embodiments, an air outlet component is provided for use in the return air outlet of a ducted air conditioner. The air outlet component includes a first return air channel with an air guide plate and a second return air channel containing a newly installed auxiliary return air outlet. A return air panel is provided above the auxiliary return air outlet. When the air conditioner's airflow demand is high, the first and second return air channels can be used for return air. By adding the second return air channel, the return air area is increased, which can reduce the fan speed and thus reduce the noise of the ducted air conditioner. When the air conditioner's airflow demand is low, the second return air channel can be used for return air. In this case, the first return air channel and the air guide plate are in a closed state, preventing dust from accumulating in the normally open air duct of the air guide plate and affecting aesthetics, while also preventing dust from accumulating in the second return air channel. Therefore, the air outlet component of this invention can not only effectively reduce the noise of the ducted air conditioner but also improve its appearance, keeping it clean and aesthetically pleasing.
