Description

Technical Field

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

[0002] In the field of air conditioning technology, the air guide frame structure is one of the core components of a floor-standing air conditioner, and its performance directly affects the user experience. Currently, most floor-standing air conditioner air guide frames on the market adopt a design with blades of the same shape arranged evenly. This design exhibits good airflow performance and a wide air delivery range in the direction of the airflow, while having minimal impact on airflow attenuation, thus meeting users' general comfort needs.

[0003] However, in practical applications, the existing air guide frame structure has significant shortcomings when it is necessary to change the airflow direction. Due to limitations in blade stroke and structural shape, a single blade can easily obstruct the airflow duct when adjusting the airflow angle, thus significantly affecting the air volume. This problem not only reduces the overall performance of the air conditioner but also weakens the user experience. Utility Model Content

[0004] The purpose of this invention is to provide an air outlet component and an air conditioner that enables the air guide vanes to maintain high air outlet efficiency under different wind direction angles, and avoids air volume loss caused by the obstruction of the air guide vanes.

[0005] The embodiments of this utility model are implemented as follows:

[0006] In a first aspect, this utility model provides an air outlet component, comprising:

[0007] An air outlet frame, wherein the air outlet frame is provided with a connected air outlet channel and an air outlet;

[0008] Multiple air guide vanes are arranged in parallel at the air outlet. Each air guide vane includes a first segment and a second segment connected together. The extension line of the first segment and the second segment form a first angle, which satisfies 0°≤n≤30°. The second segments of the multiple air guide vanes all face the air outlet channel. The line connecting the ends of the second segments of the multiple air guide vanes forms a second angle with the extension line of the first segment, which satisfies 60°≤m≤90°.

[0009] In the above embodiment, by making the extension line of the first segment and the second segment form a first angle, and the first angle ranges from 0° to 30°, that is, the guide vane formed by connecting the first segment and the second segment has a bent structure, and by making the end line of the second segment form a second angle with the extension line of the first segment, and the second angle is from 60° to 90°, the guide vane formed in this way, compared with the existing vane, can make the guide vane obstruct the airflow and reduce the amount of air overflowing between the guide vane and the air outlet frame, thereby reducing the attenuation of the air outlet airflow and increasing the effective guiding airflow of the guide vane.

[0010] In an optional implementation, the first included angle satisfies n = 10°, and / or the second included angle satisfies m = 72°.

[0011] In the above embodiment, when the first included angle is n = 10° and the second included angle is m = 72°, the best air guiding effect is achieved, and the amount of air overflow between the air guide blade and the air outlet frame is minimized.

[0012] In an optional embodiment, the air outlet assembly further includes a fan wheel, a first air outlet wall, and a second air outlet wall, the first air outlet wall and the second air outlet wall forming the air outlet channel, and the fan wheel is located at one end of the air outlet channel, the other end of the air outlet channel is provided with the air outlet, and the extension length of the first air outlet wall along the air outlet channel is less than the extension length of the second air outlet wall along the air outlet channel.

[0013] The size of the guide vane near the first air outlet wall is larger than the size of the guide vane near the second air outlet wall.

[0014] In the above embodiments, airflow overflow usually occurs between the first air outlet wall and the guide vanes. The guide vanes near the first air outlet wall guide more airflow, while the guide vanes near the second air outlet wall guide less airflow. Therefore, to avoid the risk of breakage of the guide vanes, the size of the guide vanes near the first air outlet wall is larger than that of the guide vanes near the second air outlet wall, so as to enhance the structural strength of the guide vanes near the first air outlet wall.

[0015] In an optional implementation, the width of the plurality of guide vanes gradually decreases along the direction from the first air outlet wall toward the second air outlet wall.

[0016] In the above embodiment, the width of multiple guide vanes gradually decreases along the direction from the first air outlet wall to the second air outlet wall to ensure that the structural strength of the guide vanes meets the standards.

[0017] In an optional implementation, the widths of two adjacent guide vanes are a first ratio, wherein the first ratio satisfies 0.74≤a≤0.94.

[0018] In the above embodiment, when the widths of two adjacent guide vanes are in a first ratio, and the first ratio satisfies 0.74≤a≤0.94, the structural strength of the guide vanes can be guaranteed to meet the standard.

[0019] In an optional implementation, the ratio of the minimum width to the maximum width among the plurality of guide vanes is a second ratio, wherein the second ratio satisfies 0.38≤b≤0.40.

[0020] In the above embodiments, when the width ratio of the guide vane near the first air outlet wall to the guide vane near the second air outlet wall is 0.38 to 0.40, it can be ensured that both the guide vane with the maximum width and the guide vane with the minimum width can achieve the required air guiding strength.

[0021] In an optional implementation, the length of the plurality of guide vanes gradually decreases along the direction from the first air outlet wall toward the second air outlet wall.

[0022] In the above embodiment, the length of the multiple guide vanes gradually decreases along the direction from the first air outlet wall to the second air outlet wall to ensure that the structural strength of the guide vanes meets the standard.

[0023] In an optional embodiment, the length of the air guide blade is greater than or equal to 8 mm.

[0024] In the above embodiment, the guide vane closest to the second air outlet wall is the shortest, and the length of the guide vane is greater than or equal to 8mm, so as to ensure that the structural strength of the guide vane meets the standard.

[0025] In an optional embodiment, the air outlet assembly further includes an air guide frame, wherein the plurality of air guide blades are disposed on the air guide frame, and the air guide frame is rotatably disposed on the air outlet.

[0026] In the above embodiment, the air guide frame and multiple air guide blades are integrally formed. The top or bottom end of the air guide frame is connected to the output end of the motor so that it can rotate relative to the air outlet frame under the drive of the motor, thereby driving the multiple air guide blades to rotate synchronously relative to the air outlet to achieve the purpose of left and right air sweeping.

[0027] Secondly, this utility model provides an air conditioner, including an air outlet assembly as described in any of the foregoing embodiments.

[0028] The beneficial effects of the air outlet assembly and air conditioner provided by this utility model embodiment include: by making the extension line of the first segment and the second segment form a first angle, and the first angle ranges from 0° to 30°, that is, the air guide blade formed by connecting the first segment and the second segment has a bent structure, and making the end line of the second segment form a second angle with the extension line of the first segment, and the second angle is from 60° to 90°, the air guide blade formed in this way can block the airflow and reduce the amount of air overflowing between the air guide blade and the air outlet frame, thereby reducing the attenuation of the air outlet airflow and increasing the effective guiding airflow of the air guide blade.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] In the field of air conditioning technology, the air guide frame structure is one of the core components of a floor-standing air conditioner, and its performance directly affects the user experience. Currently, most floor-standing air conditioner air guide frames on the market adopt a design with blades of the same shape arranged evenly. This design exhibits good airflow performance and a wide air delivery range in the direction of the airflow, while having minimal impact on airflow attenuation, thus meeting users' general comfort needs.

[0046] However, in practical applications, the existing air guide frame structure has significant shortcomings when it is necessary to change the airflow direction. Due to limitations in blade stroke and structural shape, a single blade can easily obstruct the airflow duct when adjusting the airflow angle, thus significantly affecting the air volume. This problem not only reduces the overall performance of the air conditioner but also weakens the user experience.

[0047] like Figure 1 The image shows a traditional crank-connecting rod left and right sweeping mechanism. The angle bisectors of the two walls of the air duct represent the overall air outlet direction (as shown by the arrow in the figure). Due to the limitations of the motion mechanism, the angle α formed between the air outlet direction and the back of the air guide frame remains constant. Therefore, it has little impact on the effective area of ​​the air entering the blades when the air guide frame is rotated to various angles.

[0048] like Figure 2 The diagram shows an integrated air guide frame structure. In this embodiment, the angle α formed between the air outlet direction and the back of the air guide frame changes with rotation. The diagram shows the extreme position of the rightward air guide, where α1 is at its minimum, α1≈15°.

[0049] In an ideal situation, from the perspective of the overall structure, the larger α is, that is, the closer the air outlet direction is to the state of being perpendicular to the inside of the air guide frame, the more conducive it is for the airflow to enter the air guide frame from the air duct. In this case, the smaller the area of ​​the air guide frame blocking the air outlet, the more conducive it is to the air outlet.

[0050] From the perspective of individual blade structure, the smaller the angle β2 formed between the air outlet direction and the sidewall of the blade closest to the air duct cavity, the smoother the air outlet and the less air volume is lost on the blade sidewall. The figure shows the rightward guiding limit position, β2≈76°.

[0051] However, existing airflow guiding structures, in the aforementioned rightward airflow guiding state, such as Figure 3The airflow simulation diagram shows that a large portion of the airflow flowing out of the outlet channel is blocked by the rightmost blade, causing some airflow to escape between the leftmost blade and the outlet frame, thus reducing the guided effective airflow.

[0052] To solve the above-mentioned technical problems, this utility model provides an air conditioner 1, such as... Figures 3 to 8 The air outlet assembly 10 of the air conditioner 1 can effectively reduce the impact of the blades on the attenuation of the air outlet volume by optimizing the blade layout and movement mode, while meeting the requirements of the blades changing the wind direction angle.

[0053] Specifically, this invention redesigns the shape and arrangement of the blades, enabling the guide vane 200 to maintain high air output efficiency under different wind angles, thus avoiding air volume loss due to obstruction by the guide vane 200.

[0054] It is understandable that this air conditioner 1 is particularly suitable for floor-standing units.

[0055] For details, please refer to Figures 3 to 7 The air outlet assembly 10 includes an air outlet frame 100 and multiple air guide vanes 200.

[0056] The air outlet frame 100 is provided with a connected air outlet channel 110 and an air outlet 120; multiple guide vanes 200 are arranged in parallel at the air outlet 120, and each guide vane 200 includes a first segment 210 and a second segment 220 connected to each other. The extension line of the first segment 210 and the second segment 220 form a first angle, which satisfies 0°≤n≤30°; the second segments 220 of the multiple guide vanes 200 all face the air outlet channel 110, and the line connecting the ends of the second segments 220 of the multiple guide vanes 200 forms a second angle with the extension line of the first segment 210, which satisfies 60°≤m≤90°.

[0057] In this embodiment, by making the extension line of the first segment 210 and the second segment 220 form a first angle, and the first angle ranges from 0° to 30°, that is, the guide vane 200 formed by connecting the first segment 210 and the second segment 220 has a bent structure, and making the end line of the second segment 220 form a second angle with the extension line of the first segment 210, and the second angle is from 60° to 90°, the guide vane 200 formed in this way, compared with the existing vane, can block the airflow and reduce the amount of air overflow between the guide vane 200 and the air outlet frame 100, thereby reducing the attenuation of the air outlet airflow and increasing the effective guiding airflow of the guide vane 200.

[0058] Specifically, when multiple guide vanes 200 are rotated to the rightward guide limit position shown in the figure, compared with the existing blade structure, the angle between the end line of the second segment 220 and the air outlet direction is effectively increased to α2, and the angle between the extension line of the second segment 220 and the air outlet direction is effectively increased to β2.

[0059] Preferably, the first included angle satisfies n = 10°, and / or the second included angle satisfies m = 72°.

[0060] In this embodiment, as shown in the figure, the optimal airflow guiding effect is achieved when the first included angle is n = 10° and the second included angle is m = 72°. In this case, the angle between the line connecting the ends of the second segment 220 and the airflow direction is α2 ≈ 33°, much larger than α1, and the angle between the extension line of the second segment 220 and the airflow direction is β2 ≈ 66°, much smaller than β1. The simulated airflow diagram is as follows. Figure 8 As shown, the airflow overflow between the guide vane 200 and the air outlet frame 100 is minimal.

[0061] Of course, in other embodiments of this utility model, the first included angle can also be other angles within the range of 0° to 30°, such as 0°, 5°, 15°, 20°, 25°, 30°, etc., and the second included angle can also be other angles within the range of 60° to 90°, such as 60°, 65°, 70°, 75°, 80°, 85°, 90°, etc., and no specific limitation is made here.

[0062] Furthermore, the air outlet assembly 10 also includes a fan wheel 300, and the air outlet frame 100 includes a first air outlet wall 130 and a second air outlet wall 140. The first air outlet wall 130 and the second air outlet wall 140 form an air outlet channel 110, and the fan wheel 300 is located at one end of the air outlet channel 110. An air outlet 120 is provided at the other end of the air outlet channel 110. The extension length of the first air outlet wall 130 along the air outlet channel 110 is less than the extension length of the second air outlet wall 140 along the air outlet channel 110.

[0063] It is worth mentioning that, with reference to the direction shown in the figure, airflow overflow usually occurs between the first air outlet wall 130 and the guide vane 200. The guide vane 200 near the first air outlet wall 130 guides more airflow, while the guide vane 200 near the second air outlet wall 140 guides less airflow. Therefore, in order to avoid the risk of breakage of the guide vane 200, the size of the guide vane 200 near the first air outlet wall 130 is larger than that of the guide vane 200 near the second air outlet wall 140, so as to enhance the structural strength of the guide vane 200 near the first air outlet wall 130.

[0064] Specifically, the width of the multiple guide vanes 200 gradually decreases along the direction from the first air outlet wall 130 toward the second air outlet wall 140.

[0065] Experiments have shown that when the widths of two adjacent guide vanes 200 are in a first ratio, and this first ratio satisfies 0.74≤a≤0.94, the structural strength of the guide vanes 200 can be guaranteed to meet the standards.

[0066] Furthermore, the ratio of the minimum width to the maximum width among the multiple guide vanes 200 is the second ratio, which satisfies 0.38≤b≤0.40.

[0067] In other words, when the width ratio of the guide vane 200 near the first air outlet wall 130 to the guide vane 200 near the second air outlet wall 140 is 0.38 to 0.40, it can be ensured that both the guide vane 200 with the maximum width and the guide vane 200 with the minimum width can achieve the required air guiding strength.

[0068] For example, the second ratio can be 0.38, 0.39, 0.40, etc. Of course, in other embodiments of this utility model, the second ratio can also be other values ​​in the range of 0.38 to 0.40, which are not specifically limited here.

[0069] Furthermore, the length of the multiple guide vanes 200 gradually decreases along the direction from the first air outlet wall 130 toward the second air outlet wall 140.

[0070] Specifically, the guide vane 200 closest to the second air outlet wall 140 is the shortest, and the length of the guide vane 200 is greater than or equal to 8mm, so as to ensure that the structural strength of the guide vane 200 meets the standard.

[0071] Furthermore, the air outlet assembly 10 also includes an air guide frame 400, with multiple air guide blades 200 disposed on the air guide frame 400, and the air guide frame 400 is rotatably disposed on the air outlet 120.

[0072] In this embodiment, the air guide frame 400 and multiple air guide blades 200 are integrally formed. The top or bottom end of the air guide frame 400 is connected to the output end of the motor so that it can rotate relative to the air outlet frame 100 under the drive of the motor, thereby driving the multiple air guide blades 200 to rotate synchronously relative to the air outlet 120 to achieve the purpose of left and right air sweeping.

[0073] In summary, this utility model provides an air outlet assembly 10 and an air conditioner 1. By making the extension line of the first segment 210 and the second segment 220 form a first angle, and the first angle ranges from 0° to 30°, that is, the air guide blade 200 formed by connecting the first segment 210 and the second segment 220 has a bent structure, and making the end line of the second segment 220 form a second angle with the extension line of the first segment 210, and the second angle is from 60° to 90°, the air guide blade 200 formed in this way can block the airflow and reduce the amount of air overflowing between the air guide blade 200 and the air outlet frame 100, thereby reducing the attenuation of the air outlet airflow and increasing the effective guiding airflow of the air guide blade 200.

[0074] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
