Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to a sweeping structure and an air conditioner. Background Technology

[0002] Air conditioners on the market are equipped with a swing mechanism, which is installed at the air duct opening of the air conditioner to achieve left and right swinging.

[0003] The connecting rod that drives the air sweeping blades in the air sweeping structure obstructs the airflow from the air conditioner, resulting in high airflow resistance, low air volume, and a poor user experience. Utility Model Content

[0004] The problem solved by this invention is that the existing air-sweeping structure linkage results in high airflow resistance and low air volume in the air conditioner.

[0005] To address the aforementioned problems, this invention provides a sweeping structure that can reduce the airflow resistance of the air conditioner and increase the air volume.

[0006] The embodiments of this utility model provide a technical solution:

[0007] A sweeping structure is applied to the air duct of an air conditioner. The sweeping structure includes a base plate, a connecting rod, and multiple sweeping blades. The multiple sweeping blades are spaced apart and erected on the base plate. The connecting rod is connected to the multiple sweeping blades and is used to drive the multiple sweeping blades to swing relative to the base plate under force.

[0008] The connecting rod has a windward wall with an air guide notch that extends in the air outlet direction of the air duct.

[0009] The sweeping structure provided in this embodiment of the utility model, in practical applications, when the airflow in the air duct reaches the surface of the windward wall of the connecting rod, the multiple air guide grooves on the connecting rod can guide the airflow through the connecting rod, reduce the obstruction effect of the windward wall on the airflow, thereby reducing the air outlet resistance and increasing the air volume.

[0010] In an optional embodiment, there are multiple air guide notches, and the multiple air guide notches are arranged sequentially on the connecting rod to form a sawtooth structure.

[0011] In an optional embodiment, the ratio of the spacing between two adjacent air guide notches to the width of the air guide notches is in the range of 0.3 to 0.6.

[0012] By setting the ratio of the spacing between the air guide notches to the width of the air guide notches to a range of 0.3 to 0.6, the airflow can be ensured to flow smoothly through the air guide notches while also ensuring that the connecting rod has high strength.

[0013] In an optional embodiment, the air guide notch is formed on the side where the windward wall connects to the bottom wall of the connecting rod.

[0014] In an alternative embodiment, the ratio of the length of the bottom wall to the length of the windward wall on the cross-section of the connecting rod is in the range of 1.5 to 1.7.

[0015] By setting the ratio of the length of the bottom wall to the length of the windward wall within the range of 1.5 to 1.7, the connecting rod as a whole has a flat structure, which prevents the windward wall from causing excessive obstruction to the airflow and further reduces the air outlet resistance.

[0016] In an optional embodiment, the end of the air guide notch away from the windward wall gradually diminishes from the inside of the connecting rod to the bottom wall, and / or,

[0017] The connecting rod also has a convex arc wall, and the two sides of the windward wall and the bottom wall that are far apart from each other are connected by the convex arc wall.

[0018] The end of the air guide notch furthest from the windward wall smoothly transitions from the inner wall of the connecting rod to the bottom wall. This serves two purposes: firstly, it prevents the connecting rod from having insufficient strength, and secondly, it ensures that the airflow entering the air guide notch can flow out smoothly, reducing its obstruction effect on the exhaust air. The convex arc wall of the connecting rod has a streamlined structure, which guides the airflow to conform to the surface of the connecting rod, reducing wind resistance.

[0019] In an optional embodiment, the convex arc wall includes a plurality of sequentially connected arc segments, extending from the windward wall to the bottom wall, wherein the plurality of arc segments are arranged sequentially and the radii of the plurality of arc segments decrease sequentially.

[0020] The radii of the multiple arc segments that make up the convex arc wall decrease sequentially, forming a streamlined structure, which further enhances the guiding effect on the airflow and further reduces wind resistance.

[0021] In an optional implementation, the width-to-depth ratio of the air guide notch is in the range of 1 to 1.5.

[0022] By setting the width-to-depth ratio of the air guide gap to a range of 1 to 1.5, it is possible to ensure that the airflow passes smoothly through the air guide gap, prevent excessive local flow velocity, and avoid turbulence.

[0023] In an optional embodiment, the connecting rod is further provided with a handle.

[0024] The handle allows the user to apply force to drive multiple sweeping blades to swing to the desired angle via a linkage, thereby controlling the sweeping angle.

[0025] In an optional embodiment, the connecting rod is further provided with a limiting part for cooperating with the beak of the air conditioner.

[0026] By moving the handle, the user moves the linkage to its limit position, which engages with the air conditioner's beak, thus achieving left and right oscillation.

[0027] An embodiment of this utility model also provides an air conditioner, including the aforementioned air-sweeping structure. The air-sweeping structure includes a base plate, a connecting rod, and multiple air-sweeping blades. The multiple air-sweeping blades are spaced apart and erected on the base plate. The connecting rod is connected to the multiple air-sweeping blades and is used to drive the multiple air-sweeping blades to swing relative to the base plate under force.

[0028] The connecting rod has a windward wall with an air guide notch that extends in the air outlet direction of the air duct.

[0029] Thanks to the beneficial effects of this air-sweeping structure, the air conditioner provided in this embodiment has the characteristics of lower airflow resistance and larger air volume, resulting in a better user experience. Attached Figure Description

[0041] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0042] Please refer to the following: Figure 1 and Figure 2 , Figure 1 The diagram shown is a schematic representation of the air-sweeping structure 100 provided in this embodiment from one perspective. Figure 2 As shown Figure 1 An enlarged schematic diagram of region A in the middle.

[0043] The air-sweeping structure 100 provided in this embodiment is applied to an air conditioner. The air-sweeping structure 100 includes a base plate 110, a connecting rod 120 and multiple air-sweeping blades 130. The multiple air-sweeping blades 130 are spaced apart and erected on the base plate 110. The connecting rod 120 is connected to the multiple air-sweeping blades 130 and is used to drive the multiple air-sweeping blades 130 to swing relative to the base plate 110 under force.

[0044] In practical applications, the base plate 110 is installed inside the air duct of the air conditioner, and the connecting rod 120 can be moved left and right manually, thereby driving multiple sweeping blades 130 to swing left and right to multiple angles within the air duct, thus achieving left and right sweeping. Alternatively, a drive mechanism, such as a motor, can be installed on the air conditioner to drive the connecting rod 120 to move left and right, thereby driving the multiple sweeping blades 130 to automatically sweep left and right.

[0045] like Figure 1 As shown, the sweeping blade 130 has a root connected to the base plate 110 and a tail portion away from the root. The connecting rod 120 is connected to the tail portions of the multiple sweeping blades 130. Furthermore, in the air outlet direction of the air duct, the connecting rod 120 is spaced apart from the base plate 110, and the connecting rod 120 is closer to the air outlet of the air duct than the base plate 110. In the height direction of the air duct, the connecting rod 120 is spaced apart from the base plate 110, and the connecting rod 120 is positioned above the base plate 110.

[0046] In this embodiment, multiple sweeping blades 130 are integrally formed with the base plate 110. Under the pulling action of the connecting rod 120, the multiple sweeping blades 130 twist relative to the base plate 110 to achieve horizontal left and right air guidance. In another embodiment, at least some of the multiple sweeping blades 130 can also be rotatably disposed on the base plate 110. Under the pulling action of the connecting rod 120, at least some of the sweeping blades 130 can also rotate to multiple angles on the base plate 110 to achieve left and right air guidance.

[0047] Since the sweeping structure 100 is located inside the air duct and on the air outlet path, it obstructs the airflow in the air duct to a certain extent, resulting in excessive air outlet resistance and reduced airflow. To solve this problem, in this embodiment, a guide notch 123 is provided on the connecting rod 120. The guide notch 123 allows airflow in the air duct to pass through, reducing the obstruction of the airflow by the connecting rod 120, thereby reducing the overall impact of the sweeping structure 100 on the airflow.

[0048] Please refer to the above. Figure 3 , Figure 3 The image shown is a partial structural cross-sectional view of connecting rod 120.

[0049] The connecting rod 120 has a windward wall 121 facing away from the air outlet of the air duct, and a bottom wall 122 opposite to the base plate 110. The windward wall 121 and the bottom wall 122 are connected at an angle, and the windward wall 121 is connected to a plurality of sweeping blades 130. It can be understood that in practical applications, the airflow in the air duct is roughly directed towards the windward wall 121 of the connecting rod 120, while the bottom wall 122 of the connecting rod 120 is roughly opposite to the bottom wall of the air duct.

[0050] In this embodiment, there are multiple air guide gaps 123. The multiple air guide gaps 123 are opened on the windward wall 121. Specifically, the multiple air guide gaps 123 are all opened on the side where the windward wall 121 connects with the bottom wall 122, and extend in the air outlet direction of the air duct.

[0051] In other words, each air guide notch 123 actually extends from both sides of the windward wall 121 and the bottom wall 122 into the interior of the connecting rod 120. In this embodiment, along the length of the connecting rod 120, multiple air guide notches 123 are located between the two ends of the connecting rod 120. That is, the two ends of the bottom wall 122 are closed to form a complete wall surface, while the space between its two ends corresponding to the positions of multiple air guide notches 123 is recessed to form a hollow structure, so as to connect the ends of the multiple air guide notches 123 away from the windward wall 121.

[0052] To ensure the strength of the connecting rod 120, in this embodiment, the end of the air guide notch 123 away from the windward wall 121 gradually diminishes from the inside of the connecting rod 120 to the bottom wall 122. That is, the end of the air guide notch 123 away from the windward wall 121 smoothly transitions from the inside of the connecting rod 120 to the bottom wall 122. In practical applications, when the air conditioner is running, when the airflow in the duct reaches the surface of the windward wall 121 of the connecting rod 120, at least part of it flows into the multiple air guide notches 123 and flows along the air guide notches 123 into the inside of the connecting rod 120, and finally flows out from the other end of the air guide notch 123, thus smoothly passing through the connecting rod 120.

[0053] Multiple air guide notches 123 are formed on the windward wall 121, reducing the area of ​​the windward wall 121 that obstructs the airflow, thereby reducing the obstruction effect of the connecting rod 120 on the air outlet of the air conditioner. Furthermore, since the end of the air guide notch 123 away from the windward wall 121 smoothly transitions to the bottom wall 122, the airflow in the air guide notch 123 can flow smoothly out of the bottom wall 122, avoiding backflow of airflow in the air guide notch 123 due to structural abrupt changes, further reducing the air outlet resistance.

[0054] In another embodiment, depending on the actual application conditions, the other end of each of the multiple air guide notches 123 may also extend to the air supply side of the connecting rod 120 facing the air outlet of the air duct.

[0055] Please refer to the following: Figure 4 and Figure 5 , Figure 4 The diagram shown is a schematic representation of the air-sweeping structure 100 provided in this embodiment from another perspective. Figure 5 As shown Figure 4 A magnified view of region B in the middle.

[0056] To ensure smooth airflow through the air guide notch 123 and prevent excessively high local flow velocities within the notch 123, thus avoiding turbulence, in this embodiment, the ratio of the width c to the depth d of the air guide notch 123 is within the range of 1 to 1.5. Preferably, in this embodiment, the width c of the air guide notch 123 is 2 mm, and the height d is 2 mm.

[0057] Furthermore, to ensure smooth airflow within the air guide notch 123 while maintaining the strength of the connecting rod 120, in this embodiment, the ratio of the distance e between two adjacent air guide notches 123 to the width c of the air guide notch 123 is within the range of 0.3 to 0.6. Preferably, in this embodiment, the distance e between two adjacent air guide notches 123 is 1.1 mm.

[0058] Preferably, in this embodiment, the multiple air guide notches 123 form a sawtooth structure, that is, the air guide notches 123 are equivalent to tooth grooves, with an flared structure, and the portion between two adjacent air guide notches 123 has a tooth-shaped structure that is wider at the top and narrower at the bottom. In this embodiment, the width c of the air guide notch 123 actually refers to the width at the middle position in the depth direction of the air guide notch 123, and the distance e between two adjacent air guide notches 123 actually refers to the distance at the middle position in the depth direction of the air guide notch 123.

[0059] In another embodiment, the structure of the air guide notch 123 can be adjusted according to the actual application conditions. For example, the air guide notch 123 can also be rectangular, triangular, or trapezoidal.

[0060] Please refer to the above. Figure 6 and Figure 7 , Figure 6 The diagram shown is a schematic representation of the sweeping structure 100 provided in this embodiment from another perspective. Figure 7 As shown Figure 6 A magnified view of region C in the middle.

[0061] To further reduce the obstruction of airflow by the connecting rod 120, in this embodiment, the ratio of the length of the bottom wall 122 to the length of the windward wall 121 in the cross-section of the connecting rod 120 is in the range of 1.5 to 1.7. In this embodiment, the connecting rod 120 is elongated, and both the bottom wall 122 and the windward wall 121 are approximately rectangular; in other words, the ratio of the width a of the bottom wall 122 to the width b of the windward wall 121 is in the range of 1.5 to 1.7.

[0062] Preferably, in this embodiment, the width a of the bottom wall 122 is 6 mm, and the width b of the windward wall 121 is 3.8 mm.

[0063] In order to ensure that the airflow can flow close to the surface of the connecting rod 120 during the process of passing through the connecting rod 120, thereby further reducing wind resistance and eddy currents, in this embodiment, the connecting rod 120 also has a convex arc wall 124, and the two sides of the windward wall 121 and the bottom wall 122 that are far apart from each other are connected by the convex arc wall 124.

[0064] It is understood that one side of the convex arc wall 124 is connected to the side of the windward wall 121 away from the bottom wall 122, and the other side is connected to the side of the bottom wall 122 away from the windward wall 121. In other words, the convex arc wall 124 extends from the side of the connecting rod 120 away from the bottom wall 122 to the side away from the windward wall 121.

[0065] In practical applications, the airflow that reaches the surface of the windward wall 121 of the connecting rod 120 in the air duct passes through the connecting rod 120 through multiple air guide gaps 123, and the other part flows along the surface of the convex arc wall 124 after passing over the windward wall 121. This reduces wind resistance, decreases eddies, and significantly increases air volume.

[0066] In this embodiment, the convex arc wall 124 includes multiple sequentially connected arc segments, extending from the windward wall 121 to the bottom wall 122. These arc segments are arranged sequentially, with their radii decreasing sequentially. It should be noted that, since the connecting rod 120 is elongated, the cross-sections of the multiple arc segments are arc-shaped, and their projections onto the bottom wall 122 are rectangular.

[0067] like Figure 7 As shown in the figure, in this embodiment, the number of arc segments constituting the convex arc wall 124 is four, from the closest to the windward wall 121 to the furthest away. The corresponding radii of the four arc segments are R1, R2, R3 and R4, respectively, where R1 > R2 > R3 > R4. Preferably, in this embodiment, R1 = 60.8 mm, R2 = 7.7 mm, R3 = 4.5 mm, and R4 = 0.4 mm.

[0068] In another embodiment, the number of arc segments constituting the convex arc wall 124 can be adjusted according to actual application conditions, and is not limited to the four in this embodiment. Furthermore, the specific radius of each arc segment can also be adjusted, as long as the radii of the multiple arc segments from the windward wall 121 to the bottom wall 122 decrease sequentially.

[0069] In this embodiment, the connecting rod 120 is also provided with a handle 125 and a limiting part 126. In practical applications, the user can move the handle 125 so that the limiting part 126 is engaged with the beak of the air conditioner to achieve left and right swinging.

[0070] Please refer to the above. Figure 8 and Figure 9 , Figure 8 The image shown is a simulated cloud map of the airflow velocity amplitude of a conventional swept structure 100. Figure 9 The image shown is a simulation cloud map of the airflow velocity amplitude of the sweep structure 100 provided in this embodiment.

[0071] like Figure 8 As shown, the traditional sweeping structure 100 significantly obstructs airflow, resulting in high exhaust resistance and pronounced vortices. For example... Figure 9 As shown, compared with the traditional sweeping structure 100, the sweeping structure 100 provided in this embodiment has a significantly reduced obstruction effect on airflow, lower airflow resistance, and a significant reduction in vortices.

[0072] Therefore, the air-sweeping structure 100 provided in this embodiment can reduce the air outlet resistance of the air conditioner and increase the air volume.

[0073] In addition, this embodiment also provides an air conditioner including the aforementioned air-sweeping structure 100. Benefiting from the beneficial effects of the air-sweeping structure 100, the air conditioner provided in this embodiment has the characteristics of lower airflow resistance and larger air volume, resulting in a better user experience.

[0074] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
