Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air duct component and an air conditioner. Background Art

[0002] To improve air conditioning energy efficiency and enhance user comfort, different air delivery methods are required in different air conditioning modes. In cooling mode, cool air is blown out from above, creating a shower-like cooling effect; in heating mode, hot air is blown out from below, creating a blanket-like heating effect. Bath-like cooling and blanket-like heating more efficiently utilize the air's inherent properties, achieving higher energy efficiency.

[0003] However, the three types of fan blades that are widely used in air-conditioning products on the market are centrifugal fan blades, cross-flow fan blades, and axial fan blades. Different fan blade types need to be configured to meet different usage requirements and air inlet and outlet methods to meet model development. However, there is no fan blade and its air duct that can switch the direction of air inlet and outlet simply by changing the direction of rotation of the fan blade. This means that the traditional air-conditioning inlet can only take in air, and the air outlet can only blow out air. Although the existing distributed air supply technology can realize air supply from both the upper and lower air outlets, in cooling mode, the lower air outlet will also blow out cold air, and in heating mode, the upper air outlet will also blow out hot air, which cannot achieve the best energy utilization rate.

[0004] Therefore, there is an urgent need on the market to provide an air duct structure that can switch the direction of air inlet and outlet. Summary of the Invention

[0005] The main purpose of the present invention is to provide an air duct component and an air conditioner to solve the problem that the air flow inlet and outlet directions of the air conditioner in the prior art cannot be switched and the work is insufficient.

[0012] Furthermore, an annular channel is provided on the outer periphery of the air guide cover, and a plurality of rectifying blades arranged at intervals are provided in the annular channel.

[0013] Furthermore, the air duct component further includes a flow guide component, and the flow guide component is arranged at the second end of the circulation channel.

[0014] Furthermore, the guide assembly includes: a positioning column; and guide vanes, wherein a plurality of guide vanes are arranged at intervals along the outer circumference of the positioning column.

[0015] Furthermore, the fan blade assembly includes a positioning sleeve and a plurality of fan blades, and the plurality of fan blades are evenly spaced along the outer circumference of the positioning sleeve.

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

[0017] Furthermore, there are two fan blade assemblies, and the two fan blade assemblies are placed in the same manner, and the two fan blade assemblies are respectively located on both sides of the mounting plate.

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

[0019] Furthermore, the distance between the fan blade assembly closest to the inwardly concave opening in the first air duct body and the first end of the circulation channel is smaller than the distance between the inwardly concave opening and the first end of the circulation channel.

[0049] See also Figures 1 to 20 As shown, according to an embodiment of the present invention, an air conditioner is provided. The air conditioner in this embodiment includes an air duct component.

[0050] See also Figures 1 to 8As shown, the air duct component in this embodiment includes an air duct body 10 and a blade assembly 20. The air duct body 10 is provided with a flow channel 121; a plurality of 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 blade assemblies 20 is located at the first end of the air duct body 10 and protrudes from an end surface 123 of the first end of the air duct body 10.

[0051] In actual operation, in the bottom-inlet, top-outlet mode, the fan assembly 20 of this embodiment rotates clockwise, causing air to flow from the first end to the second end of the circulation channel 121. In the top-inlet, bottom-outlet mode, the fan assembly 20 rotates clockwise within the circulation channel 121, causing air to flow from the second end to the first end of the circulation channel 121. The multiple fan assemblies 20 increase the air volume of the air duct component and achieve a multiple-pressure boosting effect.

[0052] Since the first end of the air duct body 10 in the present invention has a fan blade assembly 20 that protrudes from the end face 123 of the first end of the air duct body 10, that is, the fan blade assembly 20 is partially exposed to the outside of the air duct body 10, in the downward air inlet and upward air outlet mode, the fan blade assembly 20 at the first end of the air duct body 10 has both axial suction and lateral (radial) suction functions, thereby increasing the working capacity of the fan blade assembly 20 and improving the efficiency of the fan blade assembly 20; in the upward air inlet and downward air outlet mode, the fan blade assembly 20 at the first end of the air duct body 10 can throw part of the airflow out of the air duct in advance, the internal resistance of the air duct body 10 is reduced, and the working efficiency is greatly improved.

[0053] Preferably, the end surface 123 in this embodiment is perpendicular to the axis of the circulation channel 121, which is simple in structure and stable and reliable. Of course, in other embodiments of the present invention, the end surface 123 can also be set to be inclined to the axis of the circulation channel 121.

[0054] The air duct component in this embodiment also includes a drive assembly 30, which is driven by the fan blade assembly 20 to drive the fan blade assembly 20 to rotate in a clockwise direction or a counterclockwise direction, so as to facilitate the switching of the air duct component between the upper air inlet and lower air outlet mode and the lower air inlet and upper air outlet mode.

[0055] In order to facilitate installation of the driving assembly 30 , the air duct component in this embodiment further includes a mounting plate 40 . The mounting plate 40 passes through the circulation channel 121 , and the driving assembly 30 is mounted on the mounting plate 40 .

[0056] Preferably, the driving component 30 in this embodiment is a driving motor. During actual installation, the fan blade assembly 20 is installed on the output shaft 31 of the driving motor. The fan blade assembly 20 is driven to rotate clockwise or counterclockwise by the forward and reverse rotation of the driving motor, thereby switching the air duct component between the upper air inlet and lower air outlet mode and the lower air inlet and upper air outlet mode.

[0057] A deflector 41 is provided on the mounting plate 40 , and the driving assembly 30 is located inside the deflector 41 . The deflector 41 can protect the driving motor and guide and rectify the airflow.

[0058] The air guide cover 41 in this embodiment is arranged in a trumpet-shaped structure, and the end with the larger opening of the trumpet-shaped structure is arranged toward the second end of the circulation channel 121. The outer periphery of the air guide cover 41 has an annular channel 42 to facilitate the passage of fluid. A rectifying component is arranged in the annular channel 42 to facilitate the rectification of the airflow in the circulation channel 121.

[0059] The rectifying assembly in this embodiment includes a plurality of rectifying blades 43 , which are evenly arranged along the circumference of the annular channel 42 , so as to rectify the airflow in the circulation channel 121 , increase the guide vane area in the circulation channel 121 , and reduce energy loss.

[0060] See also Figures 1 to 9 As shown, the air duct component in this embodiment also includes a guide component 50, which is arranged at the second end of the circulation channel 121 and can change the airflow direction from circumferential movement to axial movement, reduce vortex losses between airflows, and improve fan efficiency.

[0061] See also Figure 9 As shown, the guide assembly 50 in this embodiment includes a positioning column 51 and a plurality of guide vanes 52. The plurality of guide vanes 52 are arranged at intervals along the outer periphery of the positioning column 51, and one end of the guide vane 52 away from the positioning column 51 is fixed to the air duct body 10. The structure is simple, stable and reliable.

[0062] See also 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 a plurality of fan blades 22 , and the plurality of fan blades 22 are evenly spaced along the outer circumference of the positioning sleeve 21 .

[0063] See also Figure 12 and Figure 13 As shown, in another embodiment of the present invention, the structure of the fan blade assembly 20 is similar to Figure 10 and Figure 11 The difference is that the fan blade assembly 20 in this embodiment further includes a splitter blade 23, which is fixed on the outer side wall of the positioning sleeve 21 and located between two adjacent fan blades 22.

[0064] See also 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, wherein the middle section of the circulation channel 121 on the first air duct body 11 is provided with an inward concave neck 111, and a plurality of fan blade assemblies 20 are respectively located on both sides of the inward concave neck 111, and an end portion of one of the plurality of fan blade assemblies 20 protrudes from the inward concave neck 111; the cross-sectional area of ​​the middle section of the circulation 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 can be switchably arranged 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.

[0065] It should be noted that the middle section of the circulation channel 121 in this embodiment refers to the interval section of the circulation channel 121 located between the air guide assembly 50 and the fan blade assembly 20 at the first end of the air duct body 10 .

[0066] In actual operation, the first duct body 11 and the second duct body 12 of this embodiment are switchably mounted on the 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, so as to adapt to different air output requirements. Specifically, the first duct body 11 of this embodiment is particularly suitable for the bottom-inlet and top-outlet mode, and the second duct body 12 is particularly suitable for the top-inlet and bottom-outlet mode.

[0067] The distance between the fan blade assembly 20 closest to the inner concave opening 111 in the first air duct body 11 and the first end of the flow channel 121 is smaller than the distance between the inner concave opening 111 and the first end of the flow channel 121. In other words, the inner concave opening 111 of the first air duct body 11 in this embodiment is located above the bottom end of the top fan blade assembly 20 (see attached FIG. Figure 2 ), so that the fan blade assembly 20 at the top can have axial suction and lateral (radial) suction functions at the same time, while increasing the secondary work capacity of the secondary air duct and improving the efficiency of the fan blade assembly 20, the effect is very significant.

[0068] Preferably, there are two fan blade assemblies 20 in this embodiment, and the two fan blade assemblies 20 are placed in the same manner, and the two fan blade assemblies 20 are respectively located on both sides of the mounting plate 40. Of course, in other embodiments of the present invention, three or more fan blade assemblies 20 can also be provided.

[0069] The two fan blade assemblies 20 in this embodiment are placed in the same manner, which means that the two fan blade assemblies 20 in the air duct body 10 are placed in the same manner, that is, the rotation directions of the fan blades 22 on the two fan blade assemblies 20 are consistent, and the end of the fan blade assembly 20 with a larger outer diameter is arranged close 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 arranged close to the first end of the air duct body 10. This method can increase the functional capacity of the fan blade assembly 20.

[0070] Recombination Figures 1 to 20 As shown, the air duct component in this embodiment is a two-stage mixed flow air duct. During actual operation, the air duct component can switch the inlet and outlet directions of the air flow to achieve two air supply modes: top-in and bottom-out or bottom-in and top-out. Figure 2 as well as Figure 4 The fan blade assembly 20 in this embodiment has wide blades and no outer sealing ring. There are two forms with splitter blades 23 and without splitter blades 23. The fan blade assembly 20 can achieve two effects in the axial and centrifugal directions during its working process. 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-in and bottom-out or bottom-in and top-out.

[0071] In cooling mode, the air conditioner adopts the bottom-in and top-out air supply mode, such as Figure 2 As shown, from the top view along the air duct component, the two-stage fan blade assembly 20 rotates counterclockwise at this time. The airflow enters from the lower end of the bottom fan blade assembly 20, and after being blown out from the bottom fan blade assembly 20, it passes through the mounting plate 40 with the rectifying blades 43. The mounting plate 40 can rectify the airflow blown out from the bottom fan blade assembly 20 while meeting the function of fixing the drive motor, and convert the circumferential motion of the airflow into axial motion to reduce the eddy loss between the airflows. The rectified airflow enters the circulation channel 121 from the lower end of the bottom fan blade assembly 20, and after doing work twice through the upper fan blade assembly 20, it is blown out from the upper end of the upper fan blade assembly 20, and then rectified twice through the guide assembly 50 and blown out of the air duct body 10, thereby realizing the bottom-in and top-out air supply mode. The flow direction of the airflow inside the fan blade assembly 20 is shown. Figure 19 shown.

[0072] In heating mode, the air conditioner adopts the top-in and bottom-out air supply mode, such as Figure 3As shown, from the top view along the air duct component, at this time, both the two-stage fan blade assemblies 20 rotate in the clockwise direction. After the airflow enters the circulation channel 121 from the top, it first passes through the guide assembly 50. At this time, the guide assembly 50 plays the dual role of inlet preselection and rectification. After that, after the upper fan blade assembly 20 works, it passes through the mounting plate 40 with the rectifying blades 43. The rectifying blades 43 can rectify the airflow blown out from the upper fan blade assembly 20, and convert the circumferential motion of the airflow into axial motion to reduce the eddy loss between the airflows. The rectified airflow enters from the upper end of the bottom fan blade assembly 20, and after the bottom fan blade assembly 20 works twice, it is finally blown out of the air duct body 10 from the lower end of the bottom fan blade assembly 20, realizing the top-in and bottom-out air supply mode. The flow direction of the airflow inside the fan blade assembly 20 is shown. Figure 20 shown.

[0073] During actual installation, the two fan blade assemblies 20 are respectively located at the two ends of the mounting plate 40. While satisfying the function of fixing the drive motor, the mounting plate 40 can also play the role of rectifying the airflow between the fan blade assemblies 20. The guide cover 41 on the mounting plate 40 is connected to the rectifying blades 43. This structure can guide the airflow so that the airflow converges to the rectifying blades 43. At the same time, it also increases the area of ​​the guide vanes in the air duct body 10, reducing energy loss. The guide vanes 52 on the upper end of the guide assembly 50 can respectively play the role of outlet rectification and inlet preselection in two modes. The rectifying blades 43 on the mounting plate 40 can change the direction of the airflow from circumferential motion to axial motion, reduce the vortex loss between the airflow, greatly improve the efficiency of the fan, and increase the air output.

[0074] The air duct component of the present invention can realize the secondary working process of the fan blade assembly 20, which can increase the working capacity of the entire fan blade assembly 20. Taking the bottom-in and top-out as an example, after the fan blade assembly 20 at the bottom works, it passes through the mounting plate 40 with the rectifying blades 43 for rectification, which can reduce the eddy current loss between the airflows. After that, it passes through the fan blade assembly 20 at the top for a second work, which can greatly improve the working capacity of the fan blade assembly 20 and can achieve the effect of secondary supercharging. Therefore, the air duct component can greatly increase the air output, reduce the energy loss of the fan, and at the same time achieve a greater supercharging effect, which can overcome greater resistance. It is applied to air conditioners with two air supply modes: top-in and bottom-out or bottom-in and top-out, and has significant effects.

[0075] 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 mode or cooling mode. As long as other structures of the air duct component of the present invention need to be used, they are within the scope of protection of the present invention.

[0076] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0077] (1) The air duct component of the present invention can realize the switching of the inlet and outlet directions of the air flow.

[0078] (2) The air duct component of the present invention can greatly increase the air volume and at the same time achieve the effect of secondary pressurization.

[0079] (3) The mounting plate with the rectifying assembly of the present invention reduces eddy current loss between airflows and improves the efficiency of the fan blade assembly. Combining the mounting plate with the rectifying assembly allows the motor to be mounted and fixed while also rectifying the airflow. The guide hood at the bottom of the mounting plate is connected to the rectifying assembly to guide the airflow, increase the guide vane area, and reduce energy loss.

[0080] (4) The concave portion between the two-stage air ducts in the present invention is located above the bottom end of the top fan blade assembly, so that the top fan blade assembly can have both axial suction and lateral (radial) suction functions, while increasing the secondary work capacity of the secondary air duct and improving the efficiency of the fan blade assembly.

[0081] (5) The fan blade assembly of the present invention is partially exposed to the outside of the air duct body. In the downward air inlet and upward air outlet mode, the fan blade assembly at the first end of the air duct body has both axial air suction and lateral (radial) air suction functions, thereby increasing the working capacity of the fan blade assembly and improving the efficiency of the fan blade assembly. In the upward air inlet and downward air outlet mode, the fan blade assembly at the first end of the air duct body can throw part of the air flow out of the air duct in advance, thereby reducing the internal resistance of the air duct body and greatly improving the working efficiency.
