Description

Technical Field

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

[0002] With the development of air conditioners, current air conditioners often use small air guide plates as auxiliary plates to compress air in order to achieve better heating and compressed air effects. In order to achieve a wider range of air supply effects, left and right air sweeping structures are generally used at the air outlet of the air conditioner. The small air guide plates and left and right air sweeping structures are in a separated state and are controlled by independent motors respectively.

[0003] It can be seen that the existing small air guide plate and the left and right air sweeping structures occupy space and have a complex structure when they exist at the same time. Summary of the invention

[0004] The problem solved by the present invention is that the existing small air guide plate and the left and right air sweeping structures occupy space and have a complex structure when they exist at the same time.

[0005] To solve the above problems, the present invention provides an air conditioner, the air conditioner has an air outlet and an air guide component arranged at the air outlet, the air guide component comprising: a plurality of sweeping blades arranged along the length direction of the air outlet; each of the sweeping blades has a first rotation axis and a second rotation axis arranged perpendicular to each other, the first rotation axes of any two of the sweeping blades are parallel and not colinear, the second rotation axes of adjacent sweeping blades are colinear, and the second rotation axis is parallel to the length direction of the air outlet; the sweeping blades have a sweeping mode and a guiding mode, in the sweeping mode, all the sweeping blades rotate synchronously back and forth around their respective first rotation axes to adjust the wind direction in the length direction of the air outlet; in the guiding mode, all the sweeping blades rotate synchronously back and forth around the second rotation axis in an extreme state to adjust the wind direction in the width direction of the air outlet; wherein the extreme state refers to any one of the sweeping blades rotating around the first rotation axis to overlap or be coplanar with the adjacent sweeping blade.

[0006] The technical effect achieved after adopting this technical solution is: the wind guide component realizes two functions of wind sweeping and wind guiding through different movement states of the wind sweeping blades, thereby saving space and having a simpler structure. Specifically, after adjacent wind sweeping blades are overlapped or coplanar, the wind sweeping blades arranged along the length direction of the air outlet can form a complete or stepped wind sweeping surface, and the entire wind sweeping surface can be flipped in the width direction of the air outlet to realize the wind guiding action; the wind sweeping blades rotate left and right respectively to realize left and right wind sweeping; the wind sweeping blades rotate around the first rotation axis to adjust the wind sweeping angle.

[0007] Furthermore, the wind sweeping blade includes: a blade leading edge and a blade trailing edge; in the wind guiding mode, the blade leading edge of the wind sweeping blade cooperates with the blade trailing edge of the adjacent wind sweeping blade.

[0008] The technical effect achieved after adopting this technical solution is as follows: the leading edge of the blade and the trailing edge of the blade cooperate, and adjacent wind-sweeping blades can be spliced ​​by rotating, thereby improving the efficiency of switching the wind-sweeping blades between the wind-sweeping mode and the wind-guiding mode; and eliminating the gap between the leading edge and the trailing edge of the adjacent wind-sweeping blades to form a complete wind-guiding plane, which can avoid air leakage during the wind-guiding process and improve the wind-guiding effect.

[0009] Furthermore, the leading edge of the blade is a convex structure; in the wind sweeping mode, the leading edge of the blade faces the outside of the air outlet; and / or, the trailing edge of the blade is a concave structure; in the wind sweeping mode, the trailing edge of the blade faces the inside of the air outlet.

[0010] The technical effect achieved after adopting this technical solution is as follows: in the wind sweeping mode, the raised structure on the leading edge of the blade can increase the wind sweeping area, thereby achieving a better wind sweeping effect; the recessed structure on the trailing edge of the blade is used to avoid the horizontal connecting rod that drives the wind sweeping blade, making the structure of the wind guide assembly more compact; the raised structure on the leading edge of the blade and the recessed structure on the trailing edge of the blade can cooperate to form a complete wind guide plane.

[0011] Furthermore, the air conditioner includes an upper diffuser section arranged above the air outlet, and the upper diffuser section includes a rotating guide portion; the air guide assembly includes a second connecting rod, the first end of the second connecting rod is connected to at least one of the wind sweeping blades, and the second end of the second connecting rod is slidably connected to the rotating guide portion, and in the air guide mode, the first end of the second connecting rod rotates around the second rotation axis, and the second end of the second connecting rod slides in the rotating guide portion.

[0012] The technical effect achieved after adopting this technical solution is as follows: the rotating guide part is used to support the second connecting rod and the wind sweeping blade, and at the same time, it limits the rotation mode of the wind sweeping blade. The wind sweeping blade can stably rotate around the first connecting rod to adjust the wind sweeping angle.

[0013] Furthermore, a second connecting rod is arranged at at least one of the first rotation axes.

[0014] The technical effect achieved after adopting this technical solution is that the wind sweeping blades reciprocate around their respective second connecting rods to adjust the wind direction in the length direction of the air outlet.

[0015] Furthermore, the second connecting rod is arranged parallel to the first rotation axis, but not colinear.

[0016] The technical effect achieved by adopting this technical solution is that the wind sweeping blade and the second connecting rod reciprocate around their respective first rotation axes to adjust the wind direction in the length direction of the air outlet.

[0017] Furthermore, the wind guide assembly also includes: a first connecting rod, which is arranged on the second rotation axis and connects adjacent wind sweeping blades.

[0018] The technical effect achieved after adopting this technical solution is as follows: adjacent wind sweeping blades rotate back and forth synchronously along the first connecting rod under extreme conditions; all wind sweeping blades can sweep the air synchronously through the first connecting rod.

[0019] Furthermore, the first connecting rod passes through the wind sweeping blade.

[0020] The technical effect achieved by adopting this technical solution is that the rotation center of the wind sweeping blade is located inside the wind sweeping blade.

[0021] Furthermore, the first rotation axis intersects with the second rotation axis, or an extension line of the second connecting rod intersects with the first connecting rod.

[0022] The technical effect achieved after adopting this technical solution is as follows: the second connecting rod and the wind sweeping blade can reciprocate together around the second rotation axis to adjust the wind direction in the width direction of the air outlet.

[0023] The present invention also provides an air conditioner control method, which is implemented by an air conditioner provided by any of the above embodiments; the air conditioner control method includes: when the cooling mode and the wind sweeping mode are turned on at the same time, as the air volume of the air conditioner decreases, the angle between the second connecting rod and the horizontal plane increases; and / or, when the heating mode and the wind sweeping mode are turned on at the same time, as the air volume of the air conditioner decreases, the angle between the second connecting rod and the horizontal plane decreases.

[0024] The technical effects achieved after adopting this technical solution are as follows: In the cooling mode, the airflow deviates to the upper diffuser section. At this time, the end of the second connecting rod connected to the rotating guide part is rotated to a position close to the air outlet, so that the airflow can flow upward along the trailing edge of the blade without blocking the airflow, so that it can follow the direction of the airflow. At the same time, the wind guide blade guides the air upward, which can avoid cold wind blowing on people and improve comfort. With the decrease of air volume, the wind sweeping blade is required to reduce the air volume loss when sweeping the air left and right. When one end of the second connecting rod connected to the rotating guide part is close to the air outlet, the angle between the second connecting rod and the horizontal plane is increased, so that the angle between the fan blade and the airflow can be reduced, thereby reducing the air volume loss. In the heating mode, the airflow deviates to the side away from the upper diffuser section. At this time, the end of the second connecting rod connected to the rotating guide part is rotated to a position away from the air outlet, so that the airflow can flow downward along the trailing edge of the blade without blocking the airflow, so that it can follow the direction of the airflow. As the wind volume decreases, the wind sweeping blade is required to reduce the wind volume loss when sweeping the wind left and right; when one end of the second connecting rod connected to the rotating guide part is away from the air outlet, the angle between the second connecting rod and the horizontal plane is reduced, which can reduce the angle between the fan blade and the airflow, thereby reducing the wind volume loss.

[0025] In summary, the above-mentioned technical solutions of the present application may have one or more of the following advantages or beneficial effects: i) the air guide component realizes the two functions of sweeping and guiding air through the different movement states of the sweeping blades, thereby saving space and making the structure simpler; ii) after the adjacent sweeping blades are overlapped or coplanar, the sweeping blades arranged along the length direction of the air outlet may form a complete or stepped sweeping surface, and the entire sweeping surface may be flipped in the width direction of the air outlet to realize the air guiding action; iii) the sweeping blades rotate left and right respectively, which may realize left and right sweeping air and adjust the wind direction in the length direction of the air outlet; iv) the sweeping blades rotate around the first connecting rod to adjust the sweeping angle, thereby following the airflow direction in cooling mode or heating mode and reducing wind resistance.

[0037] See also Figure 1-Figure 7 The present invention provides an air conditioner, which has an air outlet 101 and an air guide assembly 100 arranged at the air outlet 101, wherein the air guide assembly 100 comprises: a plurality of sweeping blades 110 arranged along the length direction of the air outlet 101; each sweeping blade 110 has a first rotation axis and a second rotation axis arranged perpendicular to each other, the first rotation axes of any two sweeping blades 110 are parallel and not collinear, the second rotation axes of adjacent sweeping blades 110 are collinear, and the second rotation axes are parallel to the length direction of the air outlet 101; the sweeping blades 110 have a sweeping mode and a guiding mode, in which all the sweeping blades 110 synchronously reciprocate around their respective first rotation axes to adjust the wind direction in the length direction of the air outlet 101; in the guiding mode, all the sweeping blades 110 synchronously reciprocate around the second rotation axis in an extreme state to adjust the wind direction in the width direction of the air outlet 101; wherein the extreme state refers to any sweeping blade 110 rotating around the first rotation axis to overlap or be coplanar with the adjacent sweeping blade 110.

[0038] In this embodiment, the wind guide assembly 100 realizes two functions of wind sweeping and wind guiding through different movement states of the wind sweeping blades 110, thereby saving space and making the structure simpler. Specifically, after adjacent wind sweeping blades 110 are overlapped or coplanar, the wind sweeping blades 110 arranged along the length direction of the air outlet 101 can form a complete or stepped wind sweeping surface, and the entire wind sweeping surface can be flipped in the width direction of the air outlet 101 to achieve the wind guiding action; the wind sweeping blades 110 rotate left and right respectively to achieve left and right wind sweeping; the wind sweeping blades 110 rotate around the first rotation axis to adjust the wind sweeping angle.

[0039] In a specific embodiment, the wind sweeping blade 110 includes: a blade leading edge 111 and a blade trailing edge 112; in the wind guiding mode, the blade leading edge 111 of the wind sweeping blade 110 cooperates with the blade trailing edge 112 of the adjacent wind sweeping blade 110. It should be noted that the blade leading edge 111 and the blade trailing edge 112 cooperate, and the adjacent wind sweeping blades 110 can be spliced ​​by rotating, thereby improving the efficiency of the wind sweeping blade 110 switching between the wind sweeping mode and the wind guiding mode; and eliminating the gap between the blade leading edge 111 and the blade trailing edge 112 of the adjacent wind sweeping blades 110 to form a complete wind guiding plane, which can avoid air leakage during the wind guiding process and improve the wind guiding effect.

[0040] Preferably, the leading edge 111 of the blade and the trailing edge 112 of the blade may be matched by side abutment, or may be overlapped with each other by means of inclined surfaces or stepped surfaces to achieve coplanarity, which is not limited here.

[0041] In a specific embodiment, the leading edge 111 of the blade is a convex structure; in the wind sweeping mode, the leading edge 111 of the blade faces the outside of the air outlet 101; and / or, the trailing edge 112 of the blade is a concave structure; in the wind sweeping mode, the trailing edge 112 of the blade faces the inside of the air outlet 101.

[0042] In a specific embodiment, the air conditioner includes an upper diffuser section 140 disposed above the air outlet 101, and the upper diffuser section 140 includes a rotation guide portion 141; the air guide assembly 100 includes a second connecting rod 130, the first end of the second connecting rod 130 is connected to at least one wind sweeping blade 110, and the second end of the second connecting rod 130 is slidably connected to the rotation guide portion 141. In the wind guide mode, the first end of the second connecting rod 130 rotates around the second rotation axis, and the second end of the second connecting rod 130 slides in the rotation guide portion 141. It should be noted that the rotation guide portion 141 is used to support the second connecting rod 130 and the wind sweeping blade 110, and at the same time, it plays a role in limiting the rotation mode of the wind sweeping blade 110, and the wind sweeping blade 110 can stably rotate around the first connecting rod 120 to adjust the wind sweeping angle.

[0043] In a specific embodiment, a second connecting rod 130 is disposed at at least one first rotation axis. The wind sweeping blades 110 reciprocate around their respective second connecting rods 130 to adjust the wind direction in the length direction of the air outlet 101 .

[0044] In another specific embodiment, the second connecting rod 130 is arranged parallel to the first rotation axis, but not colinearly. The wind sweeping blade 110 and the second connecting rod 130 reciprocate around their respective first rotation axes to adjust the wind direction in the length direction of the air outlet 101 .

[0045] It should be noted that the second connecting rod 130 has a first position and a second position in the rotating guide portion 141; in the first position, Figure 7 As shown, the first end of the second connecting rod 130 is closer to the outside of the air outlet 101 than the second end, so that the sweeping blade 110 can be used to guide the airflow to flow away from the upper diffuser section 140; in the second position, as shown Figure 6 As shown, the second end of the second connecting rod 130 is closer to the outside of the air outlet 101 than the first end, so that the wind sweeping blade 110 can be used to guide the airflow to flow in a direction close to the upper diffuser section 140 .

[0046] In a specific embodiment, the wind guide assembly 100 further includes: a first connecting rod 120, which is disposed on the second rotation axis and connects adjacent wind sweeping blades 110. The adjacent wind sweeping blades 110 reciprocate synchronously along the first connecting rod 120 in an extreme state; all wind sweeping blades 110 can be synchronously swept by the first connecting rod 120.

[0047] In a specific embodiment, the first connecting rod 120 is disposed through the wind sweeping blade 110 , so that the rotation center of the wind sweeping blade 110 is located inside the first connecting rod 120 .

[0048] In a specific embodiment, the first rotation axis intersects the second rotation axis, or the extension line of the second connecting rod 130 intersects the first connecting rod 120. The second connecting rod 130 and the wind sweeping blade 110 can reciprocate around the second rotation axis to adjust the wind direction in the width direction of the air outlet 101.

[0049] Preferably, the second connecting rod 130 is connected to the top of the sweeping blade 110 to facilitate controlling the direction of the sweeping blade 110. For example, the first end of the second connecting rod 130 is connected between the leading edge 111 and the trailing edge 112 of the blade to facilitate controlling the direction of the leading edge 111 and the trailing edge 112 of the blade.

[0050] Preferably, the rotation guide portion 141 is, for example, a guide groove, a sliding block is provided at the second end of the second connecting rod 130, and the sliding block slides in the guide groove to achieve better guiding and supporting effects. For example, the rotation guide portion 141 is, for example, an arc-shaped guide groove, the center of the arc-shaped guide groove coincides with the center of the first connecting rod 120, and the extension line of the second connecting rod 130 extending in the direction of the wind sweeping blade 110 passes through the center of the first connecting rod 120, so that the wind sweeping blade 110 can always obtain effective support during the process of rotating around the first connecting rod 120.

[0051] Preferably, the sliding block is, for example, a spherical structure, so that the friction force of the second end of the second connecting rod 130 in the rotating guide portion 141 is smaller and the sliding is smoother.

[0052] Preferably, the upper diffuser section 140 is inclined relative to the horizontal direction, and the angle between the upper diffuser section 140 and the horizontal direction is θ. When the second end of the second connecting rod 130 slides in the slide groove, the sliding angle is β, and the angle between the current position of the second connecting rod 130 and the position of the second connecting rod 130 in the slide groove near the inner end of the air outlet 101 is β0. As the second connecting rod 130 rotates outward, the β0 value continues to increase. In order to ensure that the wind sweeping blade 110 has a better air supply effect in the cooling mode and the heating mode, the range of β0 is: [0, n], n∈[90°, 160°].

[0053] Preferably, in the wind guide mode, the second end of the second connecting rod 130 is located at either end of the slide slot. For example, the second end of the second connecting rod 130 is located at one end of the slide slot close to the inner side of the air outlet 101, thereby achieving positioning so that adjacent wind guide plates are at an accurate angle that enables the leading edge 111 of the blade and the trailing edge 112 of the blade to cooperate.

[0054] The present invention also provides an air conditioner control method, which is implemented by an air conditioner provided by any of the above embodiments; the air conditioner control method includes: when the cooling mode and the wind sweeping mode are turned on at the same time, as the air volume of the air conditioner decreases, the angle between the second connecting rod 130 and the horizontal plane increases; and / or, when the heating mode and the wind sweeping mode are turned on at the same time, as the air volume of the air conditioner decreases, the angle between the second connecting rod 130 and the horizontal plane decreases.

[0055] In a specific embodiment, when the cooling mode and the wind sweeping mode are turned on at the same time, the second end of the second connecting rod 130 is located at one end of the rotating guide part 141 close to the outside of the air outlet 101, and the blade trailing edge 112 is set toward the upper diffuser section 140. It should be noted that in the cooling mode, the airflow deviates from the upper diffuser section 140. At this time, the end of the second connecting rod 130 connected to the rotating guide part 141 is rotated to a position close to the air outlet 101, and the blade trailing edge 112 is tilted toward the inner side of the air outlet 101 and upward. The airflow can flow upward along the blade trailing edge 112 without blocking the airflow, so it can follow the direction of the airflow and maintain a certain effective length in the direction of the airflow; at the same time, the wind guide blade guides the air upward, which can prevent cold wind from blowing on people and improve comfort. As the wind volume decreases, the wind sweeping blade 110 is required to reduce the wind volume loss when sweeping the wind left and right; when one end of the second connecting rod 130 connected to the rotating guide part 141 is close to the air outlet 101, the angle γ between the second connecting rod 130 and the horizontal plane is increased, which can reduce the angle between the fan blade and the airflow, thereby reducing the wind volume loss.

[0056] Preferably, in the cooling mode, the air conditioner has a plurality of air supply wind gears, and the air supply wind gears include at least a strong wind gear, a high wind gear, a medium wind gear, a low wind gear and a silent wind gear.

[0057] Preferably, the default wind guide door angle for strong wind cooling is β0=180+θ-(90-β / 2)-△β, △β∈[0,10°]. As the air volume decreases, γ=β0+△ε i , at this time △ε i Satisfy ∆ε i =(i-1)*i / 2, where i is the wind speed coefficient, i=1 at the strong wind speed, i=2 at the high wind speed, i=3 at the medium wind speed, i=4 at the low wind speed, and i=5 at the silent wind speed.

[0058] In a specific embodiment, when the heating mode and the sweeping mode are turned on at the same time, the second end of the second connecting rod 130 is located at one end of the rotating guide part 141 close to the inner side of the air outlet 101, and the blade trailing edge 112 is set away from the upper diffuser section 140. It should be noted that in the heating mode, the airflow is biased away from the upper diffuser section 140. At this time, the end of the second connecting rod 130 connected to the rotating guide part 141 is rotated to a position away from the air outlet 101, and the blade trailing edge 112 is tilted toward the inner side of the air outlet 101 and downward, so that the airflow can flow downward along the blade trailing edge 112 without blocking the airflow, so that it can follow the direction of the airflow. As the air volume decreases, it is required that the air volume loss of the sweeping blade 110 when sweeping the air left and right is reduced; when the end of the second connecting rod 130 connected to the rotating guide part 141 is away from the air outlet 101, the angle between the second connecting rod 130 and the horizontal plane is reduced, so that the angle between the fan blade and the airflow can be reduced, thereby reducing the air volume loss.

[0059] Preferably, the default wind guide door angle for strong wind gear heating is β0=θ+△β, △β∈[25°, 90-θ]. As the air volume decreases, α=β0-△ε i , at this time △ε i Satisfy: △ε i =(i-1)*i / 3.

[0060] In a specific embodiment, under other working conditions, under the action of the motor, the fan blade swings left and right on the vertical plane around the second connecting rod 130, wherein swinging to the left is a positive direction, swinging to the right is a negative direction, and the swing angle is σ, σ satisfies [-90°, +90°];

[0061] When the air conditioner is in the sweeping mode, σ satisfies [-65°, +65°], ensuring sufficient air supply volume requirements;

[0062] When the air conditioner is not in the wind sweeping mode, σ=-90° or +90°, the wind sweeping blades 110 form a plane and can be used as a small air guide plate.

[0063] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
