Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a duct component and an air conditioner. Background Technology

[0002] To improve the energy efficiency of air conditioners and enhance human comfort, different airflow patterns are required in different modes. In cooling mode, blowing cold air from above achieves a shower-like cooling effect; in heating mode, blowing hot air from below achieves a carpet-like heating effect. Shower-like cooling and carpet-like heating utilize the gas's inherent properties more efficiently, resulting in higher energy utilization.

[0003] However, the most widely used fan blades in air conditioning products on the market are mainly centrifugal fan blades, cross-flow fan blades, and axial fan blades. Different fan blade types are required to meet different usage needs and air intake / exhaust methods. However, there is currently no fan blade and its duct that can switch the airflow direction simply by changing the fan blade's rotation direction. This means that traditional air conditioner inlets can only intake air, and outlets can only exhaust air. Although existing distributed air supply technology can achieve air supply from both the top and bottom vents, in cooling mode, the bottom vent also blows out cold air, and in heating mode, the top vent also blows out hot air, which does not achieve optimal energy utilization.

[0004] Therefore, there is an urgent need in the market for a duct structure that can switch the direction of airflow in and out. Summary of the Invention

[0005] The main objective of this invention is to provide a duct component and an air conditioner to solve the problems of airflow inlet and outlet directions not being switchable and high noise in existing air conditioners.

[0006] To achieve the above objectives, according to one aspect of the present invention, a duct component is provided, comprising: a duct body having a flow channel disposed thereon, wherein a port plane at a first end of the duct body is inclined to the axis of the flow channel; and fan blade assemblies, wherein a plurality of fan blade assemblies are disposed within the flow channel and spaced apart along the axial direction of the flow channel.

[0007] Furthermore, one of the plurality of fan blade assemblies is located at the first end of the duct body and protrudes from the first end of the duct body.

[0008] Furthermore, the air duct component also includes a drive assembly, which is drivenly connected to the fan blade assembly to drive the fan blade assembly to rotate clockwise or counterclockwise.

[0009] Furthermore, the air duct component also includes: a mounting plate passing through the flow channel, and the drive assembly mounted on the mounting plate.

[0010] Furthermore, the drive assembly includes a drive motor, and the fan blade assembly is mounted on the output shaft of the drive motor.

[0011] Furthermore, the mounting plate is provided with a flow guide shroud, which is configured in a trumpet shape. The larger end of the trumpet-shaped structure faces the second end of the flow channel, and the drive assembly is located inside the flow guide shroud.

[0012] Furthermore, an annular channel is provided on the outer periphery of the fairing, and multiple spaced-apart rectifier blades are provided within the annular channel.

[0013] Furthermore, the air duct component also includes a flow guiding component, which is disposed at the second end of the flow channel.

[0014] Furthermore, the flow guiding assembly includes: a positioning post; guide vanes, with multiple guide vanes arranged at intervals along the outer periphery of the positioning post.

[0015] Furthermore, the fan blade assembly includes a positioning sleeve and multiple fan blades, with the multiple fan blades evenly spaced along the outer periphery of the positioning sleeve.

[0016] Furthermore, the fan blade assembly also includes a diverter blade, which is fixed on the outer wall of the positioning sleeve and located between two adjacent fan blades.

[0017] Furthermore, there are two fan blade assemblies, which are arranged in the same way and are located on both sides of the mounting plate.

[0018] Furthermore, the air duct body includes: a first air duct body, wherein the middle section of the flow channel on the first air duct body is provided with a concave opening, and a plurality of fan blade assemblies are respectively located on both sides of the concave opening; a second air duct body, wherein the cross-sectional area of ​​the middle section of the flow channel on the second air duct body does not change along the axial direction, and the fan blade assembly is located within the middle section; the first air duct body and the second air duct body are switchably fitted onto the outer periphery of the fan blade assembly.

[0019] Furthermore, the distance between the fan blade assembly closest to the concave opening within the first air duct body and the first end of the flow channel is less than the distance between the concave opening and the first end of the flow channel.

[0020] Furthermore, the flow channel spanned by the plurality of the fan blade assemblies forms a transverse segment, the cross-sectional area of ​​which does not change along the length of the flow channel.

[0021] According to another aspect of the present invention, an air conditioner is provided, including an air duct component, wherein the air duct component is the air duct component described above.

[0022] Applying the technical solution of this invention, in actual operation, in the bottom-inlet, top-outlet mode, the fan blade assembly of this invention can rotate clockwise, and the airflow flows from the first end to the second end of the flow channel; in the top-inlet, bottom-outlet mode, the fan blade assembly rotates clockwise within the flow channel, and the airflow flows from the second end to the first end of the flow channel. Through the action of multiple fan blade assemblies, the airflow of the duct component can be increased, while simultaneously achieving a multiple pressurization effect.

[0023] Since the port plane of the first end of the air duct body of the present invention is inclined to the axis of the flow channel, and one of the multiple fan blade assemblies is located at the first end of the air duct body and protrudes from the first end of the air duct body, when the fan blade assembly is working, it has axial and radial suction functions, increases the efficiency of the fan blade assembly, and at the same time plays the role of guiding airflow and reducing noise.

[0051] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0053] See Figures 1 to 22As shown, according to an embodiment of the present invention, an air conditioner is provided. The air conditioner in this embodiment includes a main unit 60 and an air duct component. The main unit 60 has a second air vent 80 at its bottom and a first air vent 70 at its top. The air duct component is disposed inside the main unit 60. Through the action of the first air vent 70 and the second air vent 80, it is convenient to input or output air into or out of the main unit 60.

[0054] See Figures 1 to 8 As shown, according to an embodiment of the present invention, a duct component is provided, comprising a duct body 10 and a fan blade assembly 20. The duct body 10 has a flow channel 121, and the port plane 122 of the first end of the duct body 10 is inclined to the axis of the flow channel 121. A plurality of fan blade assemblies 20 are disposed within the flow channel 121 and spaced apart along the axial direction of the flow channel 121. One of the plurality of fan blade assemblies 20 is located at the first end of the duct body 10 and protrudes from the first end of the duct body 10. In this embodiment, the inclination of the port plane 122 of the first end of the duct body 10 to the axis of the flow channel 121 means that the angle between the port plane 122 of the first end of the duct body 10 and the axis of the flow channel 121 is an acute angle.

[0055] In actual operation, in the bottom-inlet, top-outlet mode, the fan blade assembly 20 in this embodiment can rotate clockwise, and the airflow flows from the first end to the second end of the flow channel 121; in the top-inlet, bottom-outlet mode, the fan blade assembly 20 rotates clockwise within the flow channel 121, and the airflow flows from the second end to the first end of the flow channel 121. Through the action of multiple fan blade assemblies 20, the airflow of the duct component can be increased, while simultaneously achieving a multiple pressurization effect.

[0056] Since the port plane 122 of the first end of the air duct body 10 of the present invention is inclined to the axis of the flow channel 121, and one of the plurality of fan blade assemblies 20 is located at the first end of the air duct body 10 and protrudes from the first end of the air duct body 10, when the fan blade assembly 20 is working, it has axial and radial suction functions, increases the efficiency of the fan blade assembly 20, and at the same time plays the role of guiding airflow and reducing noise.

[0057] In this embodiment, the fan blade assembly 20 located at the first end of the air duct body 10 is partially exposed. The side with more exposed fan blade assembly 20 is closer to the air outlet at the first end of the air duct body 10, while the side with less exposed fan blade assembly 20 is farther from the air outlet at the first end of the air duct body 10. In the bottom-inlet and top-outlet mode, the fan blade assembly 20 at the first end of the air duct body 10 has both axial and lateral (radial) suction functions, increasing the ability of the fan blade assembly 20 to perform secondary work within the flow channel 121, improving the efficiency of the air duct components, and simultaneously guiding airflow and reducing noise. Furthermore, the inclined port plane 122 at the first end of the air duct body 10, which exposes the fan blade assembly 20, facilitates its cooperation with the inclined air outlet at the first end of the air duct body 10.

[0058] In the top-inlet and bottom-outlet mode, the fan blade assembly 20 at the first end of the flow channel 121 can throw part of the airflow out of the duct in advance, reducing the internal resistance of the flow channel 121 and greatly improving the working efficiency.

[0059] In this embodiment, the air duct component also includes a drive assembly 30, which is drivenly connected to the fan blade assembly 20 to drive the fan blade assembly 20 to rotate clockwise or counterclockwise, so as to facilitate the switching of the air duct component between the top air intake and bottom air outlet modes and the bottom air intake and top air outlet modes.

[0060] To facilitate the installation of the drive assembly 30, the air duct component in this embodiment also includes a mounting plate 40, which passes through the flow channel 121, and the drive assembly 30 is mounted on the mounting plate 40.

[0061] Preferably, the drive component 30 in this embodiment is a drive motor. In actual installation, the fan blade assembly 20 is installed on the output shaft 31 of the drive motor. By rotating the drive motor forward and backward, the fan blade assembly 20 is driven to rotate clockwise or counterclockwise, thereby enabling the air duct component to switch between the top air intake and bottom air outlet modes and the bottom air intake and top air outlet modes.

[0062] The mounting plate 40 is provided with a flow guide 41, and the drive assembly 30 is located inside the flow guide 41. The flow guide 41 serves to protect the drive motor and also guides and rectifies the airflow.

[0063] In this embodiment, the flow guide shroud 41 is configured in a trumpet shape, with the larger opening of the trumpet-shaped structure facing the second end of the flow channel 121. The outer periphery of the flow guide shroud 41 has an annular channel 42 to facilitate fluid passage. A flow rectifier is provided in the annular channel 42 to facilitate the rectification of the airflow in the flow channel 121.

[0064] The rectifier assembly in this embodiment includes multiple rectifier blades 43, which are evenly arranged around the annular channel 42 to facilitate the rectification of the airflow in the flow channel 121, increase the guide vane area in the flow channel 121, and reduce energy loss.

[0065] See Figures 1 to 9 As shown, the air duct component in this embodiment also includes a flow guide component 50, which is disposed at the second end of the flow channel 121. It can change the airflow direction from circumferential movement to axial movement, reduce vortex loss between airflows, and improve fan efficiency.

[0066] See Figure 9 As shown, the flow guiding component 50 in this embodiment includes a positioning post 51 and multiple guide vanes 52. The multiple guide vanes 52 are arranged at intervals along the outer periphery of the positioning post 51, and the end of the guide vane 52 away from the positioning post 51 is fixed on the air duct body 10. The structure is simple, stable and reliable.

[0067] See Figures 10 to 11 As shown, in a preferred embodiment of the present invention, the fan blade assembly 20 includes a positioning sleeve 21 and multiple fan blades 22, the multiple fan blades 22 being evenly arranged at intervals along the outer periphery of the positioning sleeve 21.

[0068] See Figure 12 and Figure 13 As shown, in another embodiment of the present invention, the structure of the wind turbine assembly 20 is similar to... Figure 10 and Figure 11 The basic structure is the same as that of the wind turbine assembly 20 in this embodiment. The difference is that the wind turbine assembly 20 in this embodiment also includes a diverter blade 23, which is fixed on the outer wall of the positioning sleeve 21 and located between two adjacent wind turbine blades 22.

[0069] See Figures 1 to 9 As shown, the air duct body 10 in this embodiment includes a first air duct body 11 and a second air duct body 12. The middle section of the flow channel 121 on the first air duct body 11 is provided with a concave opening 111. Multiple fan blade assemblies 20 are respectively located on both sides of the concave opening 111, and the end of one of the multiple fan blade assemblies 20 protrudes from the concave opening 111. The cross-sectional area of ​​the middle section of the flow channel 121 on the second air duct body 12 does not change along the axial direction, and the fan blade assembly 20 is located in the middle section. The first air duct body 11 and the second air duct body 12 are switchably fitted on the outer periphery of the fan blade assembly 20, the fan blade assembly 20, the mounting plate 40, the drive assembly 30, and the guide assembly 50.

[0070] It should be noted that, in this embodiment, the middle section of the flow channel 121 refers to the interval between the flow guide component 50 and the fan blade component 20 at the first end of the air duct body 10.

[0071] In actual operation, the first air duct body 11 and the second air duct body 12 in this embodiment are switchably fitted around the outer periphery of the fan blade assembly 20, the fan blade assembly 20, the mounting plate 40, the drive assembly 30, and the air guide assembly 50, which can adapt to different air outlet requirements. Specifically, the first air duct body 11 in this embodiment is particularly suitable for the bottom air inlet and top air outlet mode, and the second air duct body 12 is particularly suitable for the top air inlet and bottom air outlet mode.

[0072] The distance between the nearest fan blade assembly 20 to the concave opening 111 and the first end of the flow channel 121 within the first air duct body 11 is less than the distance between the concave opening 111 and the first end of the flow channel 121. In other words, in this embodiment, the concave opening 111 of the first air duct body 11 is located above the bottom end of the top fan blade assembly 20 (see attached diagram). Figure 2 This allows the top fan blade assembly 20 to simultaneously perform axial and lateral (radial) air intake, while also increasing the secondary air duct's secondary work capacity and improving the efficiency of the fan blade assembly 20, with very significant results.

[0073] Preferably, in this embodiment, there are two fan blade assemblies 20, which are arranged in the same way and located on opposite sides of the mounting plate 40. Of course, in other embodiments of the present invention, there may be three or more fan blade assemblies 20.

[0074] In this embodiment, the two fan blade assemblies 20 are arranged in the same way. This means that the two fan blade assemblies 20 inside the air duct body 10 are placed in the same way, that is, the fan blades 22 on the two fan blade assemblies 20 rotate in the same direction, and the end of the fan blade assembly 20 with a larger outer diameter is set closer to the second end of the air duct body 10, and the end of the fan blade assembly 20 with a smaller outer diameter is set closer to the first end of the air duct body 10. This way, the working capacity of the fan blade assembly 20 can be increased.

[0075] See Figure 23 As shown, in another embodiment of the present invention, the duct body 10 includes only one channel. During actual assembly, the flow channel 121 spanned by multiple fan blade assemblies 20 forms a transverse section, and the cross-sectional area of ​​the transverse section does not change along the length of the flow channel 121. Since the cross-sectional area of ​​the transverse section in this embodiment does not change along the length of the flow channel 121, when the airflow switches from the bottom to the top to the top to the bottom, the airflow inlet and outlet directions can be changed simply by switching the direction of the drive assembly 30. This greatly reduces the production cost of the duct components, simplifies the assembly process, and significantly improves production efficiency. Unlike the previous embodiment, it does not require switching between the first duct body 11 and the second duct body 12.

[0076] Combined again Figures 1 to 22As shown, the duct component in this embodiment is a two-stage mixed-flow duct. In actual operation, the duct component can switch the airflow inlet and outlet directions to achieve two air supply modes: top inlet and bottom outlet or bottom inlet and top outlet. Figure 2 as well as Figure 4 The present invention provides two air outlet modes for the duct component, one above the other. In this embodiment, the fan blade assembly 20 has wide blades without an outer sealing ring, and comes in two forms: with and without diverting blades 23. The fan blade assembly 20 can achieve both axial and centrifugal effects during its operation. This fan blade assembly 20 is paired with… Figure 2 and Figure 4 The first air duct body 11 and the second air duct body 12 shown can realize two air supply modes: top inlet and bottom outlet or bottom inlet and top outlet.

[0077] In cooling mode, the air conditioner uses a bottom-in, top-out airflow pattern, such as... Figure 2 As shown in the top view along the air duct component, both stages of the fan blade assembly 20 rotate counterclockwise. Airflow enters from the lower end of the bottom fan blade assembly 20, exits from the bottom fan blade assembly 20, and passes through the mounting plate 40 with rectifier blades 43. This mounting plate 40, while serving to fix the drive motor, also rectifies the airflow from the bottom fan blade assembly 20, converting the circumferential motion of the airflow into axial motion to reduce eddy current losses. The rectified airflow enters the flow channel 121 from the lower end of the bottom fan blade assembly 20, undergoes secondary work by the upper fan blade assembly 20, and exits from the upper end of the upper fan blade assembly 20. After secondary rectification by the guide assembly 50, it exits the air duct body 10, thus achieving a bottom-in, top-out air supply mode. The airflow direction inside the fan blade assembly 20 is shown in [reference needed]. Figure 19 As shown.

[0078] In heating mode, the air conditioner uses a top-in, bottom-out airflow pattern, such as... Figure 3 As shown in the top view along the duct components, both stages of the fan blade assembly 20 rotate clockwise. After entering the flow channel 121 at the top, the airflow first passes through the guide assembly 50, which serves a dual function of inlet pre-selection and rectification. After being processed by the upper fan blade assembly 20, the airflow passes through the mounting plate 40 with rectifying blades 43. The rectifying blades 43 rectify the airflow from the upper fan blade assembly 20, converting the circumferential motion of the airflow into axial motion to reduce vortex losses between airflows. The rectified airflow enters from the upper end of the lower fan blade assembly 20, undergoes a second process in the lower fan blade assembly 20, and finally exits from the lower end of the lower fan blade assembly 20 into the duct body 10, achieving an upward-inlet, downward-outlet air supply mode. The airflow direction inside the fan blade assembly 20 is shown in the figure. Figure 20 As shown.

[0079] In actual installation, the two fan blade assemblies 20 are located at opposite ends of the mounting plate 40. The mounting plate 40, while serving to fix the drive motor, also rectifies the airflow between the fan blade assemblies 20. The guide vane 41 on the mounting plate 40 is connected to the rectifier blade 43. This structure guides the airflow, causing it to converge towards the rectifier blade 43, while also increasing the area of ​​the guide vanes within the duct body 10, reducing energy loss. The guide vane 52 on the upper guide assembly 50 can function as both outlet rectification and inlet pre-selection in two modes. The rectifier blade 43 on the mounting plate 40 can change the airflow direction from circumferential to axial, reducing vortex losses between airflows, greatly improving fan efficiency, and increasing the output air volume.

[0080] The air duct component in this invention enables a secondary work process for the fan blade assembly 20, thereby increasing the overall work capacity of the fan blade assembly 20. Taking bottom-inlet and top-outlet as an example, after the bottom fan blade assembly 20 performs its work, the airflow is rectified by the mounting plate 40 with rectifier blades 43, reducing eddy current losses. Then, the top fan blade assembly 20 performs its work again, significantly improving the work capacity of the fan blade assembly 20 and providing a secondary pressurization effect. Therefore, this air duct component can greatly increase the airflow volume, reduce fan energy loss, and provide a significant pressurization effect, overcoming greater resistance. It is particularly effective when applied to air conditioners with both top-inlet / bottom-outlet and bottom-inlet / top-outlet air supply modes.

[0081] Of course, in other embodiments of the present invention, the air duct component is not limited to use in air conditioners, nor is it limited to use in heating or cooling modes. Any other structure that requires the use of the air duct component of the present invention is within the protection scope of the present invention.

[0082] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0083] (1) The air duct component of the present invention can realize the switching of airflow inlet and outlet directions.

[0084] (2) The air duct component of the present invention can greatly increase the air volume and at the same time play a secondary pressurization effect.

[0085] (3) The mounting plate with rectification components of the present invention reduces eddy current losses between airflows and improves the efficiency of the fan blade assembly. Combining the mounting plate with the rectification components allows it to rectify the airflow while satisfying the requirements for motor installation and fixation. The guide shroud at the bottom of the mounting plate is connected to the rectification components, which can guide the airflow, increase the guide vane area, and reduce energy loss.

[0086] (4) The concave opening between the two-stage air ducts in this invention is located above the bottom of the top fan blade assembly, so that the top fan blade assembly can simultaneously have axial air intake and lateral (radial) air intake functions, while increasing the secondary air duct's secondary work capacity and improving the efficiency of the fan blade assembly.

[0087] (5) The lower part of the air duct component of the present invention is cut off at an angle so that it has axial and radial air suction functions, increases the efficiency of the fan, and at the same time plays the role of guiding the air and reducing noise.
