Description

Technical Field

[0001] The present application relates to the technical field of air conditioners, and particularly to a sweeping component and an air conditioner applied to an air conditioner. Background Art

[0002] In the existing air conditioner technology, the sweeping blade is one of the key components for controlling the air flow direction. It mainly obtains power from a motor and is connected to the motor through a connecting rod structure to rotate left and right, thereby guiding the air flow at the air outlet of the air conditioner to deflect and achieve the function of left and right sweeping. In the existing technology, there are the following deficiencies in the design and control of the sweeping blade: Poor sweeping effect: The sweeping function of the traditional sweeping blade is weak. Firstly, the shape design of the traditional sweeping blade does not consider the uneven distribution of the air duct structure and air flow organization in the air conditioner duct, resulting in a mismatch between the shape of the sweeping blade and the duct structure. Secondly, through flow visualization tests, it is found that although the sweeping blade deflects at a large angle under the movement of the connecting rod mechanism, the air flow organization cannot follow the movement of the sweeping blade well, and there is still a large amount of direct blowing air leakage between the two sweeping blades, making it impossible to achieve the sweeping effect.

[0003] Low strength at the connection: The traditional sweeping blade is driven by a connecting rod, with a complex mechanical structure, and the phenomenon of white drawing is often found at the blade connection.

[0004] High noise: The traditional sweeping blade is prone to generate turbulent noise during high-speed air supply, and the air supply distance attenuation is obvious. Summary of the Invention

[0005] In order to increase the deflection angle of the sweeping blade, reduce the white drawing phenomenon of the sweeping blade, and improve the sweeping effect, the present application provides a sweeping component applied to an air conditioner.

[0006] The sweeping component applied to an air conditioner provided by the present application adopts the following technical solutions: A sweeping component applied to an air conditioner includes a mounting plate. A linear arrangement of connecting rods is provided on the bottom surface of the mounting plate. A first flexible part is provided on one side of the connecting rod, and a multi-segment blade is provided on one side of the first flexible part.

[0007] By adopting the above technical solutions, when the air conditioner drives multiple multi-segment blades to sweep left and right through a connecting rod, since the horizontal movement distance of the connecting rod is fixed, therefore, under the action of the gas flow, at this time, the deflection angle of the traditional sweeping blade is θ, while the deflection angle of the multi-segment sweeping blade is the sum of multiple angles (θ1 + θ2 +... + θ i ), through the multi-segment design, the deflection angle at the end of the sweeping blade can be increased, thereby improving the sweeping effect. At the same time, the multi-segment design can reduce the deflection angle of the air flow on a single blade (θ1 < θ, θ2 < θ..θ i<θ), the air flow can thus flow smoothly along the blade surface, which not only reduces the phenomenon of white streaks on the sweeping blade due to a large deflection angle, but also reduces the separation phenomenon of the air flow caused by too large a speed difference, so that the air flow maintains a relatively stable flow state and is more conducive to uniform distribution.

[0008] Optionally, the multi-segment blade includes a first blade, a second flexible part, and a second blade. The second flexible part is fixedly arranged between the first blade and the second blade, and one end of the first blade is fixedly connected to the first flexible part.

[0009] By adopting the above technical solution, the multi-segment blade is divided into two segments. Under the action of the first flexible part, the air flow drives the first blade to deflect at the first angle. Under the action of the second flexible part, the air flow drives the second blade to deflect at the second angle, which is beneficial to improving the stability of the multi-segment deflection of the sweeping blade. At the same time, under the action of the first flexible part and the second flexible part, the phenomenon of white streaks on the sweeping blade due to angle deflection is reduced.

[0010] Optionally, the cross-sections of the first blade and the second blade are arc-shaped.

[0011] By adopting the above technical solution, the arc-shaped surface enables the air flow to flow more smoothly along the curved surface. Compared with the flat sweeping blade, the air flow does not need to change direction sharply, thereby reducing the local resistance and the frictional resistance of the air flow.

[0012] Optionally, a trailing edge is arranged at one end of the second blade, and the trailing edge is V-shaped.

[0013] By adopting the above technical solution, according to the wind speed distribution at the air outlet of the air conditioner, the wind speed angle is large near the upper edge of the air outlet. Therefore, the length of the upper edge of the multi-segment blade is increased. Through the V-shaped trailing edge design similar to a fish tail, when the multi-segment blade swings, it is beneficial to reduce the resistance caused by the air flow.

[0014] Optionally, a plurality of pits are arranged on the side wall of the upper half of the trailing edge. The depths of the plurality of pits are respectively set to be 0.4 mm - 0.6 mm, and the edge distance between adjacent pits is 2 mm - 4 mm.

[0015] By adopting the above technical solution, the pit structure disturbs the laminar air flow on the surface, making it transition to turbulent flow faster, thereby delaying the separation of the air flow from the surface of the sphere and reducing the range of the rear low-pressure area. The regular arrangement of the pits makes the air flow distribution more uniform.

[0016] In a second aspect, the present application provides an air conditioner. A fixing frame is provided between adjacent connecting rods. The cross-sectional shape of the fixing frame is the same as that of the connecting rod. A wind-blocking folding cloth is slidably arranged inside the fixing frame, and a driving component for stretching the wind-blocking folding cloth is arranged on the fixing frame.

[0017] By adopting the above technical solution, when it is necessary to close part of the air outlet, first drive the wind-blocking folding cloth to unfold through the driving component. At this time, the wind-blocking folding cloth unfolds along the length direction of the fixing frame and closes the air outlet where the current fixing frame is located, so as to adjust the overall ventilation volume as required, which is beneficial to improving the applicable range of the air conditioner.

[0018] Optionally, the driving component includes a motor. The motor is arranged on the inner top wall of the fixing frame. A rotating shaft is rotatably arranged on the inner top wall of the fixing frame. The driving shaft of the motor is coaxially connected to the rotating shaft. The wind-blocking folding cloth includes a first fixing plate, a folding sub-cloth, and a second fixing plate. The first fixing plate is fixedly arranged on the inner wall of the fixing frame. The second fixing plate is slidably arranged inside the fixing frame. Two ends of the folding sub-cloth are respectively connected to the first fixing plate and the second fixing plate. A winding wheel is fixedly sleeved on the side wall of the rotating shaft. A strip rope is wound on the winding wheel. One end of the strip rope sequentially penetrates through the first fixing plate and the folding sub-cloth, and one end of the strip rope is connected to the second fixing plate. The fixing frame is provided with an elastic member for cooperatively driving the folding sub-cloth to stretch.

[0019] By adopting the above technical solution, when the motor is started, the driving shaft of the motor drives the rotating shaft to rotate, and the rotating shaft drives the winding wheel to rotate. The winding wheel thus unwinds the strip rope. Under the cooperative action of the elastic member, at this time the folding sub-cloth unfolds, and at this time the folding sub-cloth blocks the air outlet where the fixing frame is located, which is beneficial to improving the stability of the opening and closing adjustment of the air outlet.

[0020] Optionally, the elastic member is a spring. The spring is arranged between the first fixing plate and the second fixing plate. One end of the spring is connected to the first fixing plate, and the other end of the spring penetrates through the folding sub-cloth and is connected to the second fixing plate.

[0021] By adopting the above technical solution, when the strip rope is wound on the winding wheel, the strip rope drives the folding sub-cloth to fold through the second fixing plate. At this time, the second fixing plate compresses the spring. When the winding wheel unwinds the strip rope, the spring releases elastic force and drives the folding sub-cloth to unfold through the second fixing plate. At this time, the second fixing plate abuts against the inner wall of the air outlet duct of the air conditioner, thereby closing the air outlet where it is located, which is beneficial to improving the stability of the stretching and folding of the wind-blocking folding cloth.

[0022] Optionally, a stud is provided on one side of the first fixing plate. An adjusting nut is rotatably threaded on the side wall of the stud. One end of the adjusting nut is rotatably provided with a rotating sleeve. The rotating sleeve is slidably sleeved on the stud. One end of the spring is sleeved on the stud, and one end of the spring is fixedly connected to the rotating sleeve.

[0023] By adopting the above technical solution, when the adjusting nut is rotated forward, the adjusting nut drives the rotating sleeve to compress the spring. When the adjusting nut is rotated backward, the adjusting nut drives the rotating sleeve to release the compression of the spring, so as to adjust the elastic force of the spring to ensure that the windshield flap closes tightly at the air outlet.

[0024] To sum up, the present application includes at least one of the following beneficial technical effects: 1. When the air conditioner drives multiple multi-segment blades to sweep left and right through a connecting rod, since the horizontal movement distance of the connecting rod is fixed, under the action of the gas flow, at this time, the deflection angle of the traditional sweeping blade is θ, while the deflection angle of the multi-segment sweeping blade is the sum of multiple angles (θ1 + θ2 +... + θ i ), through the multi-segment design, the deflection angle at the end of the sweeping blade can be increased, thereby improving the sweeping effect. At the same time, the multi-segment design can reduce the deflection angle of the air flow on a single blade (θ1 < θ, θ2 < θ..θ i < θ), so that the air flow can flow smoothly along the surface of the blade. This not only reduces the phenomenon of white streaks on the sweeping blade due to large deflection angles, but also reduces the separation phenomenon caused by excessive speed differences in the air flow, thereby keeping the air flow in a relatively stable flow state and being more conducive to uniform distribution; 2. When it is necessary to close some air outlets, first drive the windshield flap to unfold through the driving assembly. At this time, the windshield flap unfolds along the length direction of the fixing frame and closes the air outlet where the current fixing frame is located, so as to adjust the ventilation volume as required, which is beneficial to expanding the application range of the air conditioner.

DETAILED DESCRIPTION

[0027] The following is combined with Figures 1-6 This application is described in further detail.

[0028] First, see Figure 1 and Figure 2 A wind sweeping assembly for an air conditioner includes a mounting plate 1, which is one of the components of the air conditioner. A connecting rod 2 is fixedly connected to the bottom surface of the mounting plate 1. To adapt to the air duct design of the air conditioner, the vertical cross-section of the connecting rod 2 is arranged in an arc shape. There are a plurality of connecting rods 2, and the plurality of connecting rods 2 are respectively distributed in a linear array along the length direction of the mounting plate 1. A first flexible portion 3 is fixedly connected to the outer wall of the connecting rod 2 near the bottom, and a multi-segment blade 4 is integrally formed and fixedly connected to the side of the first flexible portion 3 facing away from the connecting rod 2.

[0029] In the art, a connecting rod structure is installed inside the air conditioner, and the connecting rod structure is used to simultaneously drive multiple multi-section blades 4 to sweep air left and right. In practical applications, the multi-section blades 4 are divided into 2-4 sections, and since the horizontal movement distance of the connecting rod structure is constant, under the action of the airflow, such as Figure 2 As shown, the deflection angle of the traditional blade is θ, while the deflection angle of the multi-stage sweeping blade is the sum of the multiple angles (θ1+θ2+θ3+θ4). The multi-stage design can increase the deflection angle of the end of the sweeping blade, thereby improving the sweeping effect. At the same time, the multi-stage design can reduce the deflection angle of the airflow on a single blade (θ1<θ,θ2<θ,θ3<θ,θ4<θ), so the airflow can flow smoothly along the surface of the sweeping blade, which not only reduces the whitening phenomenon of the sweeping blade due to the large deflection angle, but also reduces the separation phenomenon of the airflow due to excessive speed differences, thereby keeping the airflow in a relatively stable flow state, which is more conducive to uniform distribution.

[0030] For details, see Figure 2 and Figure 3, the multi - section blade 4 in this embodiment is divided into two sections. The multi - section blade 4 includes a first blade 5 and a second blade 6. The first blade 5 is integrally and fixedly formed at one end of the first flexible part 3 away from the connecting rod 2. The second blade 6 is located on the side of the first blade 5 away from the connecting rod 2. A second flexible part 7 is integrally formed and fixedly connected between the first blade 5 and the second blade 6.

[0031] The multi - section blade 4 is divided into two sections. When the air flow moves, under the action of the first flexible part 3, the air flow drives the first blade 5 to undergo a first angular deflection, and the deflection angle is θ1. Under the action of the second flexible part 7, the air flow drives the second blade 6 to undergo a second angular deflection, and the deflection angle is θ2. And compared with the traditional blade, θ1 < θ, θ2 < θ. Therefore, the air flow can flow smoothly along the surface of the sweeping blade, which not only reduces the phenomenon of whitening caused by the large deflection angle of the sweeping blade, but also reduces the separation phenomenon caused by the too large speed difference of the air flow, so as to keep the air flow in a relatively stable flow state and is more conducive to uniform distribution.

[0032] It is worth mentioning that, referring to Figure 4 , the cross - sectional shape of the second flexible part 7 can be S - shaped, Z - shaped or C - shaped. In this embodiment, the second flexible part 7 is preferably S - shaped.

[0033] Referring to Figure 4 , the cross - sections of both the first blade 5 and the second blade 6 are arc - shaped.

[0034] Through the arc - shaped blades, the air flow can flow more smoothly along the curved surfaces of the first blade 5 and the second blade 6. Compared with the flat blade, the air flow does not need to change direction sharply, thus reducing the local resistance and the frictional resistance of the air flow.

[0035] Referring to Figure 3 , a trailing edge 8 is fixedly connected to the end of the second blade 6 away from the connecting rod 2. The shape of the trailing edge 8 is similar to that of a fish tail, and the trailing edge 8 is V - shaped.

[0036] According to the air velocity distribution at the air outlet of the air conditioner, the air velocity angle is large near the upper edge of the air outlet. Therefore, the length of the upper edge of the multi - section blade 4 is increased. Through the design of the V - shaped trailing edge 8 similar to a fish tail, when the multi - section blade 4 swings, it is beneficial to reduce the resistance caused by the air flow.

[0037] Referring to Figure 3 , a concave pit 9 is provided on the side wall of the upper half of the trailing edge 8. The number of the concave pits 9 is multiple. The depth of each concave pit 9 is 0.4 mm - 0.6 mm, and the edge distance between adjacent concave pits 9 is 2 mm - 4 mm.

[0038] The structure of the pit 9 delays the separation of the air flow from the sphere surface by disturbing the laminar air flow on the surface and making it transition to turbulent flow faster, reducing the range of the low-pressure area at the rear. The regular arrangement of the pits 9 makes the air flow distribution more uniform.

[0039] In addition, the shape of the pit 9 can be other shapes such as regular hexagon and regular pentagon.

[0040] In a second aspect, referring to Figure 1 and Figure 5 , an air conditioner, an air outlet for air flow is formed by enclosing between adjacent connecting rods 2. A fixing frame 10 is fixedly connected between adjacent connecting rods 2. In a cross-sectional view, the shape of the fixing frame 10 is the same as that of the connecting rod 2. A wind-blocking folding cloth 11 is slidably installed in the fixing frame 10. The fixing frame 10 is also provided with a driving assembly for stretching and folding the wind-blocking folding cloth 11.

[0041] Select the opening and closing quantity of the air outlet according to the use scenario or requirements. When it is necessary to close some air outlets, first drive the wind-blocking folding cloth 11 to unfold through the driving assembly. At this time, the wind-blocking folding cloth 11 unfolds along the length direction of the fixing frame 10 and closes the air outlet where the current fixing frame 10 is located. Similarly, when it is necessary to open some air outlets, also drive the wind-blocking folding cloth 11 to fold through the driving assembly, and finally open the air outlet where the current fixing frame 10 is located. Adjusting the air outlet and the overall ventilation volume as required is beneficial to improving the applicable range of the air conditioner.

[0042] It should be noted that the wind-blocking folding cloth 11 is made of nylon material, and the wind-blocking folding cloth 11 is provided with a net-shaped reinforcing rib structure to avoid abnormal noises when the air flow blows.

[0043] Specifically, referring to Figure 5 , the driving assembly includes a motor 12, the motor 12 is fixedly installed on the inner top wall of the fixing frame 10, a rotating shaft 13 is also rotatably installed on the inner top wall of the fixing frame 10, and one end of the driving shaft of the motor 12 is coaxially and fixedly connected to one end of the rotating shaft 13. The wind-blocking folding cloth 11 includes a first fixing plate 14, a folding sub-cloth 15 and a second fixing plate 16. The first fixing plate 14 is fixedly installed on the inner wall of the fixing frame 10, the second fixing plate 16 is slidably installed in the fixing frame 10, the folding sub-cloth 15 is also slidably installed in the fixing frame 10, the folding sub-cloth 15 is placed between the first fixing plate 14 and the second fixing plate 16, and one end of the folding sub-cloth 15 is fixedly connected to the first fixing plate 14, and the other end of the folding sub-cloth 15 is fixedly connected to the second fixing plate 16. A winding wheel 17 is fixedly sleeved on the side wall of the rotating shaft 13, a strip rope 18 is wound on the winding wheel 17, and one end of the strip rope 18 departing from the winding wheel 17 sequentially passes through the first fixing plate 14 and the folding sub-cloth 15 and is fixedly connected to the second fixing plate 16.

[0044] In addition, an elastic member is also installed on the fixing frame 10. The elastic member is used to cooperate with the folding sub-cloth 15 to stretch and fold. The elastic member is a spring 19. The spring 19 is located on the two symmetric inner sides of the fixing frame 10, and the spring 19 is placed between the first fixing plate 14 and the second fixing plate 16. One end of the spring 19 is fixedly connected to the first fixing plate 14, and the other end of the spring 19 penetrates through the folding sub-cloth 15 and is fixedly connected to the second fixing plate 16.

[0045] When it is necessary to open the air outlet, the motor 12 is started forward. The drive shaft of the motor 12 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the winding wheel 17 to rotate, so that the winding wheel 17 winds the strip rope 18. When the strip rope 18 is wound, the strip rope 18 folds and stores the folding sub-cloth 15 through the second fixing plate 16, and at the same time, the second fixing plate 16 squeezes the spring 19, and at this time, the air outlet is opened. When the motor 12 is started in reverse, the motor 12 drives the winding wheel 17 to unwind the strip rope 18 through the rotating shaft 13. The spring 19 releases elastic force and drives the folding sub-cloth 15 to unfold through the second fixing plate 16, and the folding sub-cloth 15 finally blocks and closes the air outlet.

[0046] See Figure 6 and Figure 7 For the convenience of adjusting the tightness of the spring 19 and improving the stability of the second fixing plate 16 against the inner wall of the air outlet, a stud 20 is fixedly connected to one side of the first fixing plate 14. A regulating nut 21 is threadedly rotated on the side wall of the stud 20. One end of the regulating nut 21 is rotatably connected to a rotating sleeve 22, and the rotating sleeve 22 is slidably sleeved on the stud 20. One end of the spring 19 is sleeved on the stud 20, and one end of the spring 19 is fixedly connected to the rotating sleeve 22.

[0047] When it is necessary to enhance the elastic force of the spring 19, first rotate the regulating nut 21 forward. The regulating nut 21 drives the rotating sleeve 22 to compress the spring 19, thereby enhancing the compression force of the spring 19 and improving the tightness of the air outlet closing.

[0048] It is worth mentioning that the motors 12 at multiple air outlets are controlled separately, which is beneficial to opening and closing the corresponding air outlets according to the requirements and controlling the overall ventilation volume.

[0049] A wind sweeping component applied to an air conditioner and the working principle of the air conditioner: The multi - segment blade 4 is divided into two segments. When the air flow moves, under the action of the first flexible part 3, the air flow drives the first blade 5 to deflect at the first angle, and the deflection angle is θ1. Under the action of the second flexible part 7, the air flow drives the second blade 6 to deflect at the second angle, and the deflection angle is θ2. And compared with the traditional blade, θ1 < θ, θ2 < θ. Therefore, the air flow can flow smoothly along the surface of the sweeping blade, which not only reduces the phenomenon of white streaks on the sweeping blade due to large deflection angles, but also reduces the separation phenomenon of the air flow caused by excessive speed differences, so as to keep the air flow in a relatively stable flow state and is more conducive to uniform distribution.

[0050] When it is necessary to open the air outlet, the motor 12 is started forward. The drive shaft of the motor 12 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the winding wheel 17 to rotate. The winding wheel 17 thus winds the cord 18. When the cord 18 is wound, the cord 18 folds and stores the folding sub - cloth 15 through the second fixing plate 16, and at the same time, the second fixing plate 16 presses the spring 19, and at this time the air outlet is opened. When the motor 12 is started in reverse, the motor 12 drives the winding wheel 17 to unwind the cord 18 through the rotating shaft 13. The spring 19 releases its elastic force and drives the folding sub - cloth 15 to unfold through the second fixing plate 16. The folding sub - cloth 15 finally blocks and closes the air outlet.

[0051] In summary, by dividing the multi - segment blade 4 into two segments, the deflection angle at the end of the sweeping blade is increased, thus improving the sweeping effect. At the same time, the multi - segment design can reduce the deflection angle of the air flow on a single blade. Therefore, the air flow can flow smoothly along the surface of the blade, which not only reduces the phenomenon of white streaks on the sweeping blade due to large deflection angles, but also reduces the separation phenomenon of the air flow caused by excessive speed differences, so as to keep the air flow in a relatively stable flow state and is more conducive to uniform distribution.

[0052] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
