Description

Technical Field

[0001] This disclosure relates to the field of air conditioning technology, and more specifically, to an air duct assembly and an air conditioning device. Background Technology

[0002] In related technologies, air conditioning equipment has a single air duct and a fixed air outlet direction, which causes cold air to descend during cooling and hot air to rise during heating, affecting the uniformity of airflow and making it difficult to meet users' air blowing needs. Utility Model Content

[0003] The purpose of this disclosure is to provide a duct assembly and an air conditioning device that can meet the different air outlet requirements of the air conditioning device.

[0004] According to a first aspect of the present disclosure, a duct assembly is provided, the duct assembly comprising: The housing has a first air vent facing downwards and a second air vent facing forwards on its bottom wall. A vortex blower, the vortex blower having an air supply channel; and At least two connecting paths, one of which is sequentially connected to the first air outlet, the air supply channel and the second air outlet, and the other of which is sequentially connected to the second air outlet, the air supply channel and the first air outlet.

[0005] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: In the duct assembly provided by this disclosure, the vortex blower has an air supply channel, and the duct assembly is provided with at least two connecting passages for respectively connecting the air supply channel. For ease of description, the at least two connecting passages can include a first connecting passage and a second connecting passage. The first connecting passage and the second connecting passage have different air inlets and outlets. For example, the air inlet of the first connecting passage can be a first air outlet, and the air outlet can be a second air outlet; the air inlet of the second connecting passage can be a second air outlet, and the air outlet can be a first air outlet. That is, the airflow flowing through the first connecting passage and the airflow flowing through the second connecting passage have different flow directions. Therefore, by selectively connecting the air supply channel to one of the first and second connecting passages, the airflow can be controlled to be delivered towards different first and second air outlets according to the actual situation, realizing that the duct assembly can perform both forward and reverse air supply. When this air duct assembly is applied to the field of air conditioning equipment, the different orientations of the first and second air inlets allow for flexible selection of airflow from the bottom to the side (i.e., forward air supply) or from the side to the bottom (i.e., reverse air supply) according to actual needs. This adapts to the airflow characteristics under different modes, meets the different air supply requirements of air conditioning equipment, and enhances the user's comfort experience in different usage scenarios.

[0006] In some possible implementations, the vortex blower has a first air supply side and a second air supply side. The first air supply side is provided with at least two first air supply outlets, and the second air supply side is provided with at least two second air supply outlets. Both the first and second air supply outlets are connected to the air supply channel, or the first air outlet is selectively connected to at least two of the first air supply outlets, and the second air outlet is selectively connected to at least two of the second air supply outlets. Thus, by providing multiple air supply outlets on both sides, multiple docking paths can be provided for the first and second connecting channels, meeting the structural requirements of the bidirectional air supply mode of the duct assembly.

[0007] In some possible implementations, the vortex blower includes an impeller, with the first air supply side and the second air supply side arranged opposite to each other in the axial direction of the impeller's rotation axis. Thus, with a single vortex blower, the axially opposite arrangement of the first and second air supply sides facilitates matching the first and second connecting passages with suitable air outlets, resulting in a simpler and more compact structure for the vortex blower and effectively saving installation space for the casing.

[0008] In some possible implementations, the first air supply side is provided with two first air supply outlets, which are arranged at circumferential intervals along the vortex blower; and / or, the second air supply side is provided with two second air supply outlets, which are arranged at circumferential intervals along the vortex blower, wherein each first air supply outlet and one of the two second air supply outlets are coaxially arranged in the axial direction of the rotation axis. Thus, the circumferentially spaced first / second air supply outlets provide a structural basis for the staggered connection of the first and second connecting passages, facilitating airflow reversal by switching the connection relationship.

[0009] In some possible implementations, the duct assembly includes a first operating mode and / or a second operating mode, the connecting passage includes a first connecting passage and a second connecting passage, and the vortex fan includes an impeller with a rotating shaft. In the first operating mode, the first air outlet is connected through the first connecting passage to one of the two second air outlets that is offset from the first air outlet in the axial direction of the rotating shaft; or, in the second operating mode, the second air outlet is connected through the second connecting passage to one of the two first air outlets that is offset from the second air outlet in the axial direction of the rotating shaft. By switching between the first and second operating modes, forward and reverse airflow of the duct assembly is achieved, effectively avoiding the problem of uneven airflow (cold air sinking in cooling and hot air floating in heating), meeting the different air outlet requirements of air conditioning equipment, and improving the user's comfort experience in different usage scenarios.

[0010] In some possible implementations, the duct assembly includes a first connecting pipe and a first connecting pipe. The first connecting pipe communicates with the first air outlet and is selectively connected to one of at least two first air supply outlets. The first connecting pipe communicates with the other of the at least two first air supply outlets and is selectively connected to either the first connecting pipe or the first air outlet. Alternatively, the duct assembly includes a second connecting pipe and a second connecting pipe. The second connecting pipe communicates with the second air outlet and is selectively connected to one of at least two second air supply outlets. The second connecting pipe communicates with the other of the at least two second air supply outlets and is selectively connected to either the second connecting pipe or the second air outlet. Thus, the coordinated arrangement of the first connecting pipe and the first connecting pipe enables flexible communication between the first air outlet and the two first air supply outlets. Similarly, the coordinated arrangement of the second connecting pipe and the second connecting pipe ensures selective communication between the second air outlet and the two second air supply outlets, facilitating the arrangement of the first and second communication paths within a limited space.

[0011] In some possible implementations, the duct assembly includes a first solenoid valve, through which the first connecting pipe is selectively connected to the first connecting pipe; and / or, the duct assembly includes a second solenoid valve, through which the second connecting pipe is selectively connected to the second connecting pipe. The first and second solenoid valves facilitate switching between the first and second connecting paths, and as switching components, they eliminate the need for manual operation, improving user convenience.

[0012] In some possible implementations, the first solenoid valve and / or the second solenoid valve are configured as electrically operated three-way valves. The first and second solenoid valves not only functionally enable switching between the first and second connecting passages, but also structurally function as connecting pipes, facilitating the setting of the first and second connecting passages.

[0013] In some possible implementations, the bottom wall of the housing is provided with a first air vent, the front side wall of the housing is provided with a second air vent, and the housing includes a central partition with a connecting port. One of the two second air vents is connected to the connecting port to communicate with the second air vent. This effectively avoids the problem of uneven airflow, where cold air sinks during cooling and hot air floats during heating, meeting the different air supply needs of the air conditioning equipment and improving the user's comfort experience in different usage scenarios.

[0014] In some possible implementations, the duct assembly includes a first pressurization structure disposed within and connected to the housing, the first pressurization structure connecting to the first air outlet and communicating with the air supply channel via the connecting passage; and / or, the duct assembly includes a second pressurization structure disposed within and connected to the housing, the second pressurization structure connecting to the second air outlet and communicating with the air supply channel via the connecting passage. This ensures sufficient power for the airflow to be delivered, enabling longer air delivery distances and wider coverage, adapting to the air supply needs of large spaces and long distances.

[0015] In some possible implementations, the first pressurization structure includes a first flared section, the cross-sectional area of ​​which gradually decreases from the first air outlet to the air supply channel; and / or, the second pressurization structure includes a second flared section, the cross-sectional area of ​​which gradually decreases from the second air outlet to the air supply channel. By utilizing fluid dynamics principles, the airflow is naturally accelerated and pressurized during its flow, eliminating the need for an additional power source and reducing energy consumption.

[0016] In some possible implementations, the first pressurizing structure is fixedly connected to the bottom wall of the housing; and / or, the second pressurizing structure is fixedly connected to the partition plate. This prevents the first and second pressurizing structures from vibrating or shifting due to airflow, ensuring stable pressurization.

[0017] According to a second aspect of the present disclosure, an air conditioning device is also provided, including the above-described air duct assembly.

[0018] In some possible implementations, the air conditioning device is a ducted air conditioner. Ducted air conditioners are characterized by uniform air delivery and gentle airflow, while also being aesthetically pleasing and space-saving.

[0019] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0022] The specific embodiments of this disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0023] In this disclosure, unless otherwise stated, the directional terms such as "upper" and "lower" generally refer to the relative positions of the corresponding components in the direction of gravity when they are in use; "inner" and "outer" generally refer to the relative positions of the corresponding components with respect to their own contours; and "front" and "rear" generally refer to the relative positions of the corresponding components in the horizontal direction when they are in use. In the air duct assembly provided in this disclosure, the orientation of the second air outlet 12 can be considered as "front," and vice versa. Furthermore, the terms "first," "second," etc., are used to distinguish one element from another and do not have sequential or importance implications. In addition, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0024] This disclosure provides an exemplary embodiment of an air duct assembly. The air duct assembly 100 is optionally applicable to air conditioning equipment, including ducted air conditioners, wall-mounted air conditioners, cabinet air conditioners, fresh air units, and air purification equipment, etc. For ease of description, a ducted air conditioner is used as an example for illustrative purposes below.

[0025] According to the exemplary embodiments provided in this disclosure, refer to Figures 1 to 6 As shown, a duct assembly is provided. The duct assembly 100 includes: a housing 1, a vortex fan 2, and at least two connecting passages. The bottom wall of the housing 1 is provided with a first air outlet 11 opening downward and a second air outlet 12 opening forward. The vortex fan 2 has an air supply channel 24. One of the at least two connecting passages is sequentially connected to the first air outlet 11, the air supply channel 24, and the second air outlet 12, and the other of the at least two connecting passages is sequentially connected to the second air outlet 12, the air supply channel 24, and the first air outlet 11.

[0026] Through the above technical solution, the duct assembly 100 provided in this disclosure includes a vortex blower 2 with an air supply channel 24. The duct assembly 100 is provided with at least two connecting passages for respectively connecting the air supply channel 24. For ease of description, the at least two connecting passages may include a first connecting passage 31 and a second connecting passage 32. The first connecting passage 31 and the second connecting passage 32 have different air inlets and outlets. For example, the air inlet of the first connecting passage 31 may be a first air outlet 11, and the air outlet may be a second air outlet 12; the air inlet of the second connecting passage 32 may be a second air outlet 12, and the air outlet may be a first air outlet 11. That is, the airflow flowing through the first connecting passage 31 and the airflow flowing through the second connecting passage 32 have different flow directions. Therefore, by selectively connecting the air supply channel 24 to one of the first connecting passage 31 and the second connecting passage 32, the airflow can be controlled to be delivered towards different first air outlets 11 and second air outlets 12 according to the actual situation, thus enabling the duct assembly 100 to perform both forward and reverse air supply. When the air duct assembly 100 is applied to the field of air conditioning equipment, since the first air outlet 11 and the second air outlet 12 have different orientations, the airflow can be flexibly selected to enter from the bottom and exit from the side (i.e., forward air supply) or enter from the side and exit from the bottom (i.e., reverse air supply) according to actual needs. This fits the airflow characteristics of different modes, meets the different air supply needs of air conditioning equipment, and improves the user's comfort experience in different usage scenarios.

[0027] It should be noted that in this disclosure, both ends of the first connecting passage 31 and the second connecting passage 32 are connected to the first air outlet 11 and the second air outlet 12, and the airflow directions through the first connecting passage 31 and the second connecting passage 32 are different. In some other embodiments, the housing 1 may also be provided with two first air outlets 11 and two second air outlets 12, with the first connecting passage 31 and the second connecting passage 32 respectively connected to their respective first air outlets 11 and second air outlets 12, and the airflow directions through the first connecting passage 31 and the second connecting passage 32 are different. This can also achieve the function of both forward and reverse air supply in the duct assembly 100. This disclosure does not impose any specific limitations on this.

[0028] In the air duct assembly provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 2 and Figure 6 As shown, the vortex blower 2 may have a first air supply side 21 and a second air supply side 22. The first air supply side 21 may be provided with at least two first air supply ports 211, and the second air supply side 22 may be provided with at least two second air supply ports 221. The first air supply ports 211 and the second air supply ports 221 may both be connected to the air supply channel 24. The first air outlet 11 may be selectively connected to at least two first air supply ports 211, and the second air outlet 12 may be selectively connected to at least two second air supply ports 221. In other words, the first connecting passage 31 connects one of the two first air outlets 211 and one of the two second air outlets 221 to achieve connection with the air supply channel 24, and the second connecting passage 32 connects one of the two first air outlets 211 and the other of the two second air outlets 221 to achieve connection with the air supply channel 24. Thus, both the first connecting passage 31 and the second connecting passage 32 can be connected to the first air supply side 21 and the second air supply side 22 of the vortex fan 2. Therefore, the airflow through the first connecting passage 31 and the second connecting passage 32 can be accelerated and then delivered under the drive of the vortex fan 2. In this way, the arrangement of multiple air outlets on both sides provides multiple docking paths for the first connecting passage 31 and the second connecting passage 32, meeting the structural requirements of the bidirectional air supply mode of the duct assembly 100.

[0029] In the air duct assembly provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 6As shown, the vortex blower 2 may include an impeller, and the first air supply side 21 and the second air supply side 22 may be arranged opposite to each other in the axial direction of the impeller's rotation axis. Thus, with only one vortex blower 2, the axially opposite arrangement of the first air supply side 21 and the second air supply side 22 facilitates matching the first connecting passage 31 and the second connecting passage 32 with suitable air outlets, making the structure of the vortex blower 2 simpler and more compact, effectively saving installation space in the housing 1. Simultaneously, the airflow flows axially along the impeller's rotation axis, reducing radial backflow losses and improving the transmission efficiency of the airflow passing through the first connecting passage 31 and the second connecting passage 32. Furthermore, through the above design, the duct assembly 100 can achieve both forward and reverse air supply using only one vortex blower 2.

[0030] In the air duct assembly provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 6 As shown, the first air supply side 21 can be provided with two first air supply ports 211, which can be arranged at intervals along the circumference of the vortex blower 2, and / or, the second air supply side 22 can be provided with two second air supply ports 221, which can be arranged at intervals along the circumference of the vortex blower 2. Each first air supply port 211 and one of the two second air supply ports 221 can be coaxially arranged in the axial direction of the rotation axis. The circumferentially spaced first air supply ports 211 / second air supply ports 221 provide a structural basis for the staggered connection of the first connecting passage 31 and the second connecting passage 32, facilitating airflow reversal by switching the connection relationship. For example, a valve can be provided on the first air supply side 21 to selectively open or close the two first air supply ports 211, and a valve can be provided on the second air supply side 22 to selectively open or close the two second air supply ports 221, facilitating the switching of the first connecting passage 31 and the second connecting passage 32 and avoiding flow direction limitations caused by a single layout.

[0031] In the duct assembly provided in this disclosure, as an exemplary embodiment, the duct assembly 100 may include a first operating mode and / or a second operating mode, the connecting passage may include a first connecting passage 31 and a second connecting passage 32, and the vortex fan 2 includes an impeller with a rotating shaft. That is, the duct assembly 100 may include one of the first operating mode or the second operating mode, or it may include both the first operating mode and the second operating mode.

[0032] In the first working mode, refer to Figure 2As shown, the first air outlet 211 can be connected to one of the two second air outlets 221 that is offset from the first air outlet 211 in the axial direction of the rotation axis through the first connecting passage 31. That is, at this time, the first air outlet 211 is connected to the second air outlet 221 that is not on the same axis. The second connecting passage 32 can be cut off. The airflow enters the air supply channel 24 through the first air outlet 11 and the first air outlet 211 of the first air supply side 21. After being accelerated by the vortex fan 2, it flows to the second air outlet 221 of the second air supply side 22, and then is sent out through the second air outlet 12, thereby realizing the side air outlet from the bottom air inlet.

[0033] In the second working mode, refer to Figure 3 As shown, the second air outlet 221 can be connected to one of the two first air outlets 211 that is offset from the second air outlet 221 in the axial direction of the rotation axis through the second connecting passage 32. That is, at this time, the second air outlet 221 is connected to the first air outlet 211 that is not on the same axis. The first connecting passage 31 can be cut off. The airflow enters the air supply channel 24 through the second air outlet 12 and the second air outlet 221 of the second air supply side 22. After being accelerated by the vortex fan 2, it flows to the first air outlet 211 of the first air supply side 21, and then is sent out through the first air outlet 11, thereby realizing the side air intake and bottom air outlet.

[0034] The air duct assembly provided in this disclosure is selectively connected to the first connecting passage 31 and the second connecting passage 32 via the air supply channel 24, allowing the air duct assembly 100 to switch between a first operating mode and a second operating mode. This enables both forward air supply (airflow from the bottom and then to the side) and reverse air supply (airflow from the side and then to the bottom). By changing the direction of airflow, it helps to accelerate indoor air circulation, improve indoor air circulation efficiency, and enhance the user experience.

[0035] This improvement in air circulation efficiency has different effects on different devices. Taking a device that can cool or heat as an example, when cooling in summer, the cold airflow presses the hot airflow to the bottom, forming a stratification of cold at the top and hot at the bottom. In related technologies, a single air inlet and outlet path, such as side air inlet and bottom air outlet, prevents the hot airflow at the bottom from being quickly drawn into the device. In this case, the reversible air supply is switched to bottom air inlet and side air outlet, so that the hot airflow at the bottom can be quickly drawn into the device.

[0036] In the air duct assembly provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 2 , Figure 3 and Figure 6As shown, the duct assembly 100 may include a first connecting pipe 33 and a first connecting pipe 34. The first connecting pipe 33 may be connected to a first air outlet 11 and selectively connected to one of at least two first air supply outlets 211. The first connecting pipe 34 may be connected to the other of the at least two first air supply outlets 211 and selectively connected to either the first connecting pipe 33 or the first air outlet 11. That is, one end of the first connecting pipe 33 is connected to the first air outlet 11, and the other end is selectively connected to one of the first air supply outlets 211. One end of the first connecting pipe 34 may be selectively connected to the first air outlet 11, and the other end may be connected to the other first air supply outlet 211. Alternatively, one end of the first connecting pipe 34 may be selectively connected to the first connecting pipe 33, and the other end may be connected to the other first air supply outlet 211. And / or, the duct assembly 100 may include a second connecting pipe 35 and a second connecting pipe 36. The second connecting pipe 35 may be connected to the second air outlet 12 and selectively connected to one of at least two second air outlets 221. The second connecting pipe 36 may be connected to the other of the at least two second air outlets 221 and selectively connected to either the second connecting pipe 35 or the second air outlet 12. That is, one end of the second connecting pipe 35 is connected to the second air outlet 12 and the other end is selectively connected to one of the second air outlets 221, while one end of the second connecting pipe 36 may be selectively connected to the second air outlet 12 and the other end is connected to the other second air outlet 221. Alternatively, one end of the second connecting pipe 36 may be selectively connected to the second connecting pipe 35 and the other end is connected to the other second air outlet 221. In this way, the first connecting pipe 33 and the first connecting pipe 34 are arranged in a coordinated manner to achieve flexible connection between the first air outlet 11 and the two first air supply outlets 211. Similarly, the second connecting pipe 35 and the second connecting pipe 36 are arranged in a coordinated manner to ensure selective connection between the second air outlet 12 and the two second air supply outlets 221, which facilitates the arrangement of the first connecting passage 31 and the second connecting passage 32 in a limited space.

[0037] As an exemplary embodiment, reference is made to Figure 6 As shown, the first pair of connecting pipes 34 can be constructed as L-shaped pipes, with one end selectively connected to the first connecting pipe 33 and the other end connected to the first air outlet 211. This facilitates the arrangement of the first connecting passage 31 within a limited space while ensuring selective connection between the first connecting passage 31 and the air supply channel 24. Similarly, the second pair of connecting pipes 36 can also be constructed as L-shaped pipes, with both ends connected to the second connecting pipe 35 and the second air outlet 221, respectively. This facilitates the arrangement of the second connecting passage 32 within a limited space while ensuring selective connection between the second connecting passage 32 and the air supply channel 24.

[0038] In other embodiments, the first connecting pipe 34 / second connecting pipe 36 can also be constructed in any suitable shape to be directly connected between the first air outlet 11 and the first air supply outlet 211, which can also realize the connection between the first connecting passage 31 / second connecting passage 32 and the air supply channel 24. This disclosure does not impose any specific limitations on this.

[0039] Based on the above embodiments, as an exemplary embodiment, refer to Figure 2 or Figure 3 As shown, the duct assembly 100 may include a first solenoid valve 41, and the first connecting pipe 34 may be selectively connected to the first connecting pipe 33 through the first solenoid valve 41; and / or, the duct assembly 100 may include a second solenoid valve 42, and the second connecting pipe 36 may be selectively connected to the second connecting pipe 35 through the second solenoid valve 42.

[0040] Thus, in the first working mode, refer to Figure 2 As shown, the first solenoid valve 41 can control the first connecting pipe 33 to disconnect from the first connecting pipe 34, and the second solenoid valve 42 can control the second connecting pipe 35 to connect with the second connecting pipe 36. In this way, the airflow entering the first connecting pipe 33 through the first air outlet 11 can enter the air supply channel 24 through the first air outlet 211, and after being accelerated by the vortex fan 2, it enters the second connecting pipe 36 through the second air outlet 221, and can be sent out through the second connecting pipe 35 from the second air outlet 12, realizing the positive air supply of the air duct assembly 100.

[0041] In the second working mode, refer to Figure 3 As shown, the first solenoid valve 41 can control the first connecting pipe 33 to connect with the first connecting pipe 34, and the second solenoid valve 42 can control the second connecting pipe 35 to disconnect from the second connecting pipe 36. In this way, the airflow entering the second connecting pipe 35 through the second air outlet 12 can enter the air supply channel 24 through the second air outlet 221, and after being accelerated by the vortex fan 2, it enters the first connecting pipe 34 through the first air outlet 211, and can be sent out through the first air outlet 11 through the first connecting pipe 33, realizing the reverse air supply of the air duct assembly 100.

[0042] Among them, the first solenoid valve 41 and the second solenoid valve 42 serve as switching components between the first connecting passage 31 and the second connecting passage 32, eliminating the need for manual operation and improving user convenience.

[0043] In the air duct assembly provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 6As shown, the first solenoid valve 41 and / or the second solenoid valve 42 can be configured as an electrically operated three-way valve. In this way, the first solenoid valve 41 and the second solenoid valve 42 not only functionally enable switching between the first connecting passage 31 and the second connecting passage 32, but also structurally function as connecting pipes. The first solenoid valve 41 selectively connects to the first connecting pipe 33, the first connecting pipe 34, and the two first air outlets 211, while the second solenoid valve 42 selectively connects to the second connecting pipe 35, the second connecting pipe 36, and the two second air outlets 221, thereby facilitating the configuration of the first connecting passage 31 and the second connecting passage 32. Furthermore, the electrically operated three-way valve features a mature structure, fast response speed, and high airtightness, which improves the reliability of switching between the first connecting passage 31 and the second connecting passage 32.

[0044] In the air duct assembly provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 4 and Figure 5 As shown, the bottom wall of the housing 1 can be provided with a first air vent 11, and the front side wall of the housing 1 can be provided with a second air vent 12. The housing 1 can also include a partition 15, which can be provided with a connecting port 151. One of the two second air outlets 221 can be connected to the connecting port 151 to communicate with the second air vent 12. By setting the first air vent 11 on the bottom wall of the housing 1 and the second air vent 12 on the front side wall of the housing 1, taking the cooling and heating process as an example, the air duct assembly 100 can adopt a first working mode when cooling, so that cold air is delivered from the second air vent 12 with the opening facing forward. This can prevent cold air from falling directly and accumulating on the ground. When heating, the air duct assembly 100 can adopt a second working mode, so that hot air is delivered from the first air vent 11 with the opening facing downward. This can prevent hot air from rising and accumulating at the top, effectively avoiding the problem of uneven airflow where cold air sinks when cooling and hot air rises when heating. This meets the different air outlet requirements of the air conditioning equipment and improves the user's comfort experience in different usage scenarios.

[0045] In addition, the partition plate 15 can separate the internal space of the housing 1, dividing the housing 1 into a fan chamber 13 and a heat exchange chamber 14 that are isolated from each other. The fan chamber 13 can be equipped with a vortex fan 2, and the heat exchange chamber 14 can be equipped with a heat exchanger 6, so as to reasonably divide the internal space of the housing 1, avoid the airflow at the first air outlet 11 from interfering with the components in the fan chamber 13, and improve the reliability of the air supply of the air duct assembly 100.

[0046] In the air duct assembly provided in this disclosure, as an exemplary embodiment, reference is made to... Figure 2 , Figure 3 or Figure 6As shown, the duct assembly 100 may include a first pressurization structure 51, which is disposed within and connected to the housing 1. The first pressurization structure 51 is connected to the first air outlet 11 and connected to the air supply channel 24 via a connecting passage. Alternatively, the duct assembly 100 may include a second pressurization structure 52, which is disposed within and connected to the housing 1. The second pressurization structure 52 is connected to the second air outlet 12 and connected to the air supply channel 24 via a connecting passage. By configuring the first pressurization structure 51 and the second pressurization structure 52, the airflow passing through the first air outlet 11 and the second air outlet 12 can be pressurized, ensuring sufficient power for the airflow to be delivered, thus enabling a longer delivery distance and wider coverage, adapting to the air supply needs of large spaces and long distances.

[0047] Based on the above embodiments, as an exemplary embodiment, refer to Figure 2 , Figure 3 or Figure 6 As shown, the first pressurization structure 51 may include a first flared section 511, the cross-sectional area of ​​which gradually decreases from the first air outlet 11 to the air supply channel 24; and / or, the second pressurization structure 52 may include a second flared section 521, the cross-sectional area of ​​which gradually decreases from the second air outlet 12 to the air supply channel 24. The gradually decreasing first and second flared sections 511 and 521 utilize fluid dynamics principles to naturally accelerate and pressurize the airflow during its flow, eliminating the need for an additional power source and reducing energy consumption. Simultaneously, the gradually changing cross-sectional area prevents eddies and turbulence caused by abrupt changes in cross-section, ensuring smooth airflow, improving pressurization efficiency and air supply uniformity, reducing wind noise generated by airflow impact, improving the quietness of the duct assembly 100, and enhancing the user experience.

[0048] Based on the above embodiments, as an exemplary embodiment, refer to Figure 5 As shown, the first pressurizing structure 51 can be fixedly connected to the bottom wall of the housing 1; and / or, the second pressurizing structure 52 can be fixedly connected to the partition plate 15. In this way, it is possible to avoid the first pressurizing structure 51 and the second pressurizing structure 52 from vibrating or shifting due to airflow, thus ensuring a stable pressurizing effect.

The air duct assembly 100 has all the beneficial effects described above. The air conditioning equipment includes ducted air conditioners, wall-mounted air conditioners, cabinet air conditioners, fresh air units, and air purification equipment, etc.
