Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0002] Currently, with the continuous improvement of living standards, people have increasingly higher requirements for the functionality of air conditioners. To improve the diversity of airflow patterns, air conditioners with dual air deflectors are now available on the market. In this type of air conditioner, if the distance between the two air deflectors is too large, it will result in a wide gap between the two deflectors when the air conditioner is off, creating a large black slit and affecting the aesthetics of the air conditioner; if the distance between the two air deflectors is too small, it will cause the two deflectors to interfere with each other during rotation, affecting the airflow effect. Summary of the Invention

[0003] The problem solved by this invention is how to prevent interference when the two guide vanes rotate while minimizing the black gap generated when the two guide vanes are closed, thereby enhancing the air guiding effect and ensuring the aesthetics of the air conditioner.

[0004] To solve the above problems, the technical solution of the present invention is implemented as follows:

[0005] This invention provides an air conditioner, including a housing, a first air guide plate, and a second air guide plate. The first and second air guide plates are spaced apart and rotatably installed within the housing. The first air guide plate has a first rotation axis, and its perpendicular bisector intersects the first air guide plate at a first intersection point. The second air guide plate has a second rotation axis, and its perpendicular bisector intersects the second air guide plate at a second intersection point. The first and second air guide plates satisfy the following relationship: L = x(M+N); 1.1 ≤ x ≤ 1.7; where L is the distance between the first and second rotation axes, M is the distance between the first rotation axis and the first intersection point, N is the distance between the second rotation axis and the second intersection point, and x is a preset coefficient. Compared with the prior art, the air conditioner provided by this invention, by employing a first and second air guide plate with a certain positional relationship, can prevent interference when the two air guide plates rotate while minimizing the black gap generated when the two air guide plates are closed, thus enhancing the air guiding effect and ensuring the aesthetics of the air conditioner.

[0006] Furthermore, both the first and second guide vanes are arc-shaped. The perpendicular bisector of the longest chord of the first guide vane intersects the first guide vane at a first intersection point, and the perpendicular bisector of the longest chord of the second guide vane intersects the second guide vane at a second intersection point.

[0007] Furthermore, the distance between the first and second rotation axes ranges from 50 mm to 70 mm, and / or has a preset coefficient of 1.33. A reasonable preset coefficient can prevent interference between the first and second air guides during rotation, while further reducing the width of the black gap when the first and second air guides are closed, thus improving the user experience. A reasonable distance between the first and second rotation axes can increase the air guiding area of ​​each air guide while maintaining the same overall dimensions of the air conditioner, thereby increasing the diversity of air outlet methods and preventing interference between the first and second air guides during rotation.

[0008] Furthermore, the distance between the first rotation axis and the first intersection point is equal to the distance between the second rotation axis and the second intersection point. The first guide vane and the second guide vane are identical in size and shape to facilitate manufacturing, installation, and maintenance.

[0009] Furthermore, the first rotation axis is located on the perpendicular bisector of the longest chord of the first guide vane, and / or the second rotation axis is located on the perpendicular bisector of the longest chord of the second guide vane. This minimizes the space required for the rotation of the first and second guide vanes, thereby saving space within the air conditioner and preventing uneven or even jammed rotation of the first and second guide vanes, thus avoiding noise and improving the user experience.

[0010] Furthermore, the first guide plate is densely provided with multiple first overflow holes, which are used to supply and discharge airflow, and the angle formed between the airflow directions of any two first overflow holes is less than or equal to 42 degrees; and / or, the second guide plate is densely provided with multiple second overflow holes, which are used to supply and discharge airflow, and the angle formed between the airflow directions of any two second overflow holes is less than or equal to 42 degrees. The airflow volume and velocity of the airflow flowing out from the first and second overflow holes are extremely low, and the airflow flows out slowly from the multiple first and second overflow holes to achieve the zero-wind-feel airflow function of the air conditioner and ensure the heat exchange effect during zero-wind-feel airflow.

[0011] Furthermore, the outer casing includes a middle frame and a front panel. The front panel is mounted on the outside of the middle frame, forming an auxiliary air outlet channel between the front panel and the middle frame. A first guide plate and a second guide plate work together to guide the airflow into the auxiliary air outlet channel. The front panel is densely covered with multiple third overflow holes, which communicate with the auxiliary air outlet channel and are used to discharge the airflow within the auxiliary air outlet channel. The airflow from the third overflow holes has extremely low volume and velocity, and the airflow flows slowly out from the multiple third overflow holes on the front panel to achieve the zero-wind-feel airflow function of the air conditioner.

[0012] Furthermore, the first air deflector is positioned closer to the front panel than the second air deflector, and the first rotation axis is located diagonally above the second rotation axis. This allows the air deflector and the second air deflector to complement each other, further enhancing the airflow effect and improving the user experience.

[0013] Furthermore, the air conditioner also includes an air outlet frame, which is detachably connected to the middle frame. Both the first and second air guide plates are rotatably mounted on the air outlet frame. The air outlet frame supports the first and second air guide plates, which can rotate relative to the air outlet frame to guide the airflow.

[0014] Furthermore, the air conditioner also includes a first stepper motor and a second stepper motor, both mounted on the air outlet frame. The first stepper motor is driven by a first guide plate, and the second stepper motor is driven by a second guide plate. The first and second stepper motors operate independently, allowing users to operate only the first guide plate without operating the second guide plate, or only the second guide plate without operating the first guide plate, thereby further enhancing the versatility of the air outlet configuration.

Detailed Implementation

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Please refer to the reference. Figures 1 to 3 This invention provides an air conditioner 100 for regulating indoor temperature. It can prevent interference when the two air deflectors rotate while minimizing the black gaps created when the two air deflectors are closed, thus enhancing the airflow effect and ensuring the aesthetics of the air conditioner 100.

[0028] It should be noted that the air conditioner 100 is a wall-mounted air conditioner. The air conditioner 100 is mounted on an indoor wall and is used to blow hot or cold air into the room to achieve the function of heating or cooling, thereby regulating the indoor temperature and meeting the user's needs.

[0029] The air conditioner 100 includes a housing 110, a first guide vane 120, a second guide vane 130, an air outlet frame 140, a first stepper motor 150, and a second stepper motor 160. The first guide vane 120 and the second guide vane 130 are spaced apart and are rotatably mounted inside the housing 110. Both the first guide vane 120 and the second guide vane 130 can rotate relative to the housing 110 to achieve the air guiding function. Specifically, the outer casing 110 is provided with an air guiding space 111 and an air outlet 112 communicating with the air guiding space 111. The air outlet 112 is located on the outside of the air guiding space 111. The first guide plate 120 and the second guide plate 130 are both located inside the air guiding space 111. The air guiding space 111 is used to communicate with the volute air duct 170. The cross-flow fan 180 installed in the volute air duct 170 can generate negative pressure to drive the airflow through the volute air duct 170 into the air guiding space 111, so that under the air guiding action of the first guide plate 120 and the second guide plate 130, it is blown into the room through the air outlet 112.

[0030] It is worth noting that the first guide vane 120 has a first rotation axis, and the first guide vane 120 can rotate around the first rotation axis. The perpendicular bisector of the first guide vane 120 intersects the first guide vane 120 at a first intersection point. The second guide vane 130 has a second rotation axis, and the second guide vane 130 can rotate around the second rotation axis. The perpendicular bisector of the second guide vane 130 intersects the second guide vane 130 at a second intersection point.

[0031] Furthermore, the first guide vane 120 and the second guide vane 130 satisfy the following relationship:

[0032] L = x(M + N);

[0033] 1.1 ≤ x ≤ 1.7;

[0034] In the formula, L is the distance between the first rotation axis and the second rotation axis, M is the distance between the first rotation axis and the first intersection point, N is the distance between the second rotation axis and the second intersection point, and x is a preset coefficient. The above formula limits three parameters: the recess depth of the first guide plate 120 (distance between the first rotation axis and the first intersection point), the recess depth of the second guide plate 130 (distance between the second rotation axis and the second intersection point), and the distance between the first guide plate 120 and the second guide plate 130 (distance between the first rotation axis and the second rotation axis). This limits the shape and arrangement of the first guide plate 120 and the second guide plate 130, thereby preventing interference when the first guide plate 120 and the second guide plate 130 rotate while minimizing the black seam generated when the first guide plate 120 and the second guide plate 130 are closed, enhancing the airflow effect, and ensuring the aesthetics of the air conditioner 100.

[0035] In this embodiment, both the first guide plate 120 and the second guide plate 130 are arc-shaped. Arc-shaped guide plates have lower wind resistance and better airflow guidance. Furthermore, both sides of the guide plates can guide airflow, increasing the versatility of the air outlet patterns of the air conditioning unit. Specifically, the perpendicular bisector of the longest chord of the first guide plate 120 intersects its outer convex surface at a first intersection point, and the perpendicular bisector of the longest chord of the second guide plate 130 intersects its outer convex surface at a second intersection point.

[0036] Specifically, when the air conditioner 100 is in the off state, both the first guide plate 120 and the second guide plate 130 rotate to the middle position. At this time, the concave surfaces of the first guide plate 120 and the second guide plate 130 are aligned with the volute air duct 170. The first guide plate 120 and the second guide plate 130 together close the air outlet 112. However, inevitably, there is a certain gap between the first guide plate 120 and the second guide plate 130, so that users can see a black seam between the first guide plate 120 and the second guide plate 130. This invention reduces the width of the black seam by limiting the shape and arrangement of the first guide plate 120 and the second guide plate 130, thus ensuring the aesthetics of the air conditioner 100 and improving the user experience.

[0037] When the air conditioner 100 is in the start-up state, the air conditioner 100 has a variety of different air outlet modes. In different air outlet modes, the first guide plate 120 and the second guide plate 130 need to be rotated to different positions. The present invention limits the shape and arrangement of the first guide plate 120 and the second guide plate 130 to ensure that the first guide plate 120 and the second guide plate 130 do not interfere with each other during rotation, so as to enhance the air guiding effect and ensure the service life of the air conditioner 100.

[0038] It should be noted that the distance between the first rotation axis and the second rotation axis is in the range of 50 mm to 70 mm; or, the preset coefficient is 1.33; or, while the distance between the first rotation axis and the second rotation axis is in the range of 50 mm to 70 mm, the preset coefficient is 1.33.

[0039] In this embodiment, the preset coefficient is 1.33. A reasonable preset coefficient can prevent interference between the first guide plate 120 and the second guide plate 130 when they rotate, while further reducing the width of the black gap generated when the first guide plate 120 and the second guide plate 130 are closed, thus improving the user experience. However, it is not limited to this. In other embodiments, the preset coefficient can be 1.1 or 1.7, and the value of the preset coefficient is not specifically limited.

[0040] It is worth noting that the distance between the first rotation axis and the second rotation axis is between 50 mm and 70 mm. A reasonable distance between the first rotation axis and the second rotation axis can increase the air guiding area of ​​the first guide plate 120 and the second guide plate 130 while keeping the appearance size of the air conditioner 100 unchanged, thereby improving the diversity of the air outlet mode of the air conditioner 100 and preventing the first guide plate 120 and the second guide plate 130 from interfering with each other when rotating.

[0041] In this embodiment, the distance between the first rotation axis and the second rotation axis is 60 mm, but it is not limited to this. In other embodiments, the distance between the first rotation axis and the second rotation axis can be 50 mm or 70 mm. The size of the distance between the first rotation axis and the second rotation axis is not specifically limited.

[0042] In this embodiment, the distance between the first rotation axis and the first intersection point is equal to the distance between the second rotation axis and the second intersection point, i.e., M = N. The first guide plate 120 and the second guide plate 130 are identical in size and shape to facilitate manufacturing, installation, and maintenance. However, this is not the only embodiment. In other embodiments, the distance between the first rotation axis and the first intersection point may not be equal to the distance between the second rotation axis and the second intersection point. There is no specific limitation on whether the distance between the first rotation axis and the first intersection point or the distance between the second rotation axis and the second intersection point is larger or smaller.

[0043] Furthermore, the first rotation axis is located on the perpendicular bisector of the longest chord of the first guide plate 120, so as to minimize the movement space required for the first guide plate 120 to rotate, thereby saving the usable space inside the air conditioner 100. Since the perpendicular bisector of the longest chord of the first guide plate 120 divides the first guide plate 120 into two parts, the first rotation axis located on this perpendicular bisector can ensure that the first guide plate 120 is subjected to uniform force during rotation, avoiding uneven rotation or even jamming, avoiding noise generation, and improving the user experience.

[0044] Similarly, the second rotation axis is located on the perpendicular bisector of the longest chord of the second guide plate 130, so as to minimize the movement space required for the second guide plate 130 to rotate, thereby saving the usable space inside the air conditioner 100. Since the perpendicular bisector of the longest chord of the second guide plate 130 divides the second guide plate 130 into two parts, the second rotation axis located on this perpendicular bisector can ensure that the second guide plate 130 is subjected to uniform force during rotation, avoiding uneven rotation or even jamming, avoiding noise generation, and improving the user experience.

[0045] For ease of understanding, the first rotation axis is represented as point A, the second rotation axis as point B, the first intersection point as point C, the second intersection point as point D, the longest chord of the first guide vane 120 as line segment EF, the perpendicular bisector of the longest chord of the first guide vane 120 as the line containing points A and C, the longest chord of the second guide vane 130 as line segment GH, and the perpendicular bisector of the longest chord of the second guide vane 130 as the line containing points B and D.

[0046] In this embodiment, the first guide plate 120 is provided with a plurality of first overflow holes 121, and the second guide plate 130 is provided with a plurality of second overflow holes 131. The first overflow holes 121 and the second overflow holes 131 are both used to supply airflow for discharge, so as to realize the zero-wind-feel airflow function of the air conditioner 100. Specifically, when the air conditioner 100 is in the zero-wind-feel air outlet state, both the first guide plate 120 and the second guide plate 130 are closed. The air outlet can flow into the room through the multiple first overflow holes 121 on the first guide plate 120 and the multiple second overflow holes 131 on the second guide plate 130. Since the diameters of the first overflow holes 121 and the second overflow holes 131 are small, the air volume and velocity of the air outlet flowing out from the first overflow holes 121 and the second overflow holes 131 are extremely low. The air outlet slowly flows out from the multiple first overflow holes 121 and the multiple second overflow holes 131 to achieve the zero-wind-feel air outlet function of the air conditioner and ensure the heat exchange effect when the air outlet is in the zero-wind-feel air outlet state.

[0047] Furthermore, the angle formed between the air outlet directions of any two first overflow holes 121 is less than or equal to 42 degrees; or, the angle formed between the air outlet directions of any two second overflow holes 131 is less than or equal to 42 degrees; or, while the angle formed between the air outlet directions of any two first overflow holes 121 is less than or equal to 42 degrees, the angle formed between the air outlet directions of any two second overflow holes 131 is also less than or equal to 42 degrees. In this embodiment, the maximum value of the angle formed between the air outlet directions of any two first overflow holes 121 is 40 degrees, and the maximum value of the angle formed between the air outlet directions of any two second overflow holes 131 is also 40 degrees. In this way, under the premise of facilitating manufacturing and production, the wind resistance caused by the first overflow holes 121 and the second overflow holes 131 can be effectively reduced, and noise can be avoided. At the same time, since the multiple first overflow holes 121 and the multiple second overflow holes 131 have different orientations, they can be used to adjust the air outlet direction, making the air outlet direction more dispersed and improving the zero-wind-feel air outlet effect.

[0048] It should be noted that the outer casing 110 includes a middle frame 113 and a front panel 114. The front panel 114 is installed on the outside of the middle frame 113 and is used to shield the middle frame 113 to improve the overall aesthetics of the air conditioner 100. An auxiliary air outlet duct 115 is formed between the front panel 114 and the middle frame 113. The auxiliary air outlet duct 115 is connected to the air guide space 111. The first guide plate 120 and the second guide plate 130 are used together to guide the airflow into the auxiliary air outlet duct 115. The front panel 114 is densely provided with multiple third overflow holes 116. The third overflow holes 116 are connected to the auxiliary air outlet channel 115. The third overflow holes 116 are used to discharge the air outlet air in the auxiliary air outlet channel 115. The air outlet air in the auxiliary air outlet channel 115 can flow outward through multiple third overflow holes 116 at the same time. Since the diameter of the third overflow holes 116 is small, the air volume and air velocity of the air outlet air flowing out from the third overflow holes 116 are extremely low. The air outlet air flows out slowly from multiple third overflow holes 116 on the front panel 114 to achieve the zero-wind-feel air outlet function of the air conditioner 100.

[0049] Furthermore, the air outlet frame 140 is detachably connected to the middle frame 113. The first guide plate 120 and the second guide plate 130 can be rotatably mounted on the air outlet frame 140. The air outlet frame 140 can support the first guide plate 120 and the second guide plate 130. The first guide plate 120 and the second guide plate 130 can rotate relative to the air outlet frame 140 to achieve the function of guiding the airflow.

[0050] In this embodiment, the first guide vane 120 has a first rotation axis, with the first rotation axis center located on the first rotation axis, and the first guide vane 120 can rotate around the first rotation axis. The second guide vane 130 has a second rotation axis, with the second rotation axis center located on the second rotation axis, and the second guide vane 130 can rotate around the second rotation axis. The first rotation axis and the second rotation axis are parallel and spaced apart, so that the air guiding effects of the first guide vane 120 and the second guide vane 130 complement each other, further enhancing the air guiding effect and improving the user experience.

[0051] Specifically, the first guide plate 120 is positioned relative to the second guide plate 130 near the front panel 114, that is, the first guide plate 120 is positioned on the side of the second guide plate 130 near the front panel 114, and the first rotation axis is located diagonally above the second rotation axis (the vertical direction is the up-down direction), that is, the first rotation axis is located diagonally above the second rotation axis. When the air conditioner 100 is in a zero-wind-feel airflow state, the second guide plate 130 is used to guide the airflow towards the area where the first guide plate 120 is located, and the first guide plate 120 is used to guide the airflow towards the auxiliary airflow channel 115, so that the airflow continuously enters the auxiliary airflow channel 115, thereby allowing the airflow to continuously flow out from the multiple third overflow holes 116 on the front panel 114, realizing the zero-wind-feel airflow function.

[0052] In this embodiment, both the first stepper motor 150 and the second stepper motor 160 are mounted on the air outlet frame 140. The first stepper motor 150 is driven by the first guide plate 120 and is used to drive the first guide plate 120 to rotate. The second stepper motor 160 is driven by the second guide plate 130 and is used to drive the second guide plate 130 to rotate. Specifically, the first stepper motor 150 and the second stepper motor 160 operate independently, that is, the operation of the first guide plate 120 and the operation of the second guide plate 130 do not interfere with each other. Users can operate only the first guide plate 120 without operating the second guide plate 130, or only operate the second guide plate 130 without operating the first guide plate 120, so as to further improve the diversity of the air outlet mode of the air conditioner 100.

[0053] Please refer to the reference. Figures 4 to 9 ( Figures 4 to 9(The lines and arrows in the diagram indicate the direction of airflow.) It's worth noting that the air conditioner 100 has six modes: Zero Wind Mode, Enhanced Heating Mode, Normal Heating Mode, Cooling Mode, Constant Temperature Mode, and Dual-Zone Airflow Mode. Zero Wind Mode has extremely low airflow volume and speed, so users barely feel the direct airflow, resulting in high comfort. This mode can provide both heating and cooling, suitable for sleeping or working environments. Enhanced Heating Mode has high airflow volume and speed, with the airflow blowing vertically downwards to the ground and then diffusing outwards and upwards for rapid heating, suitable for scenarios where the indoor temperature is extremely low and urgent heating is needed. Normal Heating Mode has high airflow volume and speed, with the airflow blowing downwards at an angle, allowing heat to continuously diffuse downwards for heat preservation, suitable for scenarios where the indoor temperature needs to be maintained after reaching a certain level. Cooling Mode… The first mode has a high air volume and speed, with the airflow tilted downwards in the second direction, allowing the cool air to continuously diffuse downwards to maintain cooling. This mode is suitable for scenarios where the indoor temperature needs to be maintained after it has dropped to a certain level. The second mode has a lower air volume and speed, with the airflow tilted downwards in the third direction. This mode can both heat and cool, and is suitable for scenarios where the indoor temperature needs to be maintained after it has fully met the user's requirements. The third mode has an adjustable air volume and speed, with the airflow blowing outwards in two different directions. This mode can both heat and cool, and is suitable for scenarios where temperature control needs to be applied to different areas of the room simultaneously.

[0054] Specifically, a first angle is formed between the first direction and the horizontal direction, a second angle is formed between the second direction and the horizontal direction, and a third angle is formed between the third direction and the horizontal direction. The first angle is greater than the third angle, and the third angle is greater than the second angle. This means that the airflow from the normal heating mode is lower than that from the constant temperature mode, and the airflow from the constant temperature mode is lower than that from the cooling mode. For ease of understanding, let's denote the first angle as 'a', the second angle as 'b', and the third angle as 'c'.

[0055] When the air conditioner 100 is in zero-wind mode, the first guide plate 120 and the second guide plate 130 are both rotated to the middle position. At this time, the concave surfaces of the first guide plate 120 and the second guide plate 130 are set facing the volute air duct 170 to play the role of catching the wind and guiding the airflow towards the direction close to the auxiliary air outlet duct 115. Specifically, when the airflow from the volute duct 170 reaches the concave surfaces of the first guide plate 120 and the second guide plate 130, a portion of the airflow flows outward directly through the first overflow hole 121 on the first guide plate 120 and the second overflow hole 131 on the second guide plate 130, achieving zero-wind-feel airflow in the area of ​​the first guide plate 120 and the second guide plate 130. The other portion of the airflow, guided by the concave surfaces of the first guide plate 120 and the second guide plate 130, flows into the auxiliary airflow duct 115 and flows outward through the third overflow hole 116 on the front panel 114, achieving zero-wind-feel airflow in the area of ​​the front panel 114. This effectively increases the airflow volume for zero-wind-feel airflow, ensuring heat exchange efficiency.

[0056] When the air conditioner 100 is in enhanced heating mode, both the first guide plate 120 and the second guide plate 130 are rotated to the left limit position. At this time, the outer convex surface of the first guide plate 120 is set to face the auxiliary air outlet duct 115 to block the auxiliary air outlet duct 115 and prevent the air outlet airflow from flowing into the auxiliary air outlet duct 115. The outer convex surface of the second guide plate 130 is set to face the first guide plate 120 to avoid guiding the air outlet airflow to the area where the first guide plate 120 is located. Specifically, part of the airflow blowing out from the volute duct 170 bends along the concave surface of the first guide plate 120 and flows vertically downwards, while another part bends along the concave surface of the second guide plate 130 and flows vertically downwards. During this process, a small amount of airflow may pass through the first overflow hole 121 on the first guide plate 120 and the second overflow hole 131 on the second guide plate 130. However, since the airflow direction is different from the opening direction of the first overflow hole 121 and the second overflow hole 131, this small amount of airflow can be ignored. In this way, the first guide plate 120 and the second guide plate 130 simultaneously serve as air guides, ensuring that the airflow flows vertically downwards, improving the accuracy of airflow guidance, and enhancing the airflow guidance effect.

[0057] When the air conditioner 100 is in normal heating mode, both the first guide plate 120 and the second guide plate 130 are rotated to the right limit position. At this time, the concave surface of the first guide plate 120 is set to face the auxiliary air outlet duct 115, and the concave surface of the second guide plate 130 is set to face the first guide plate 120. The convex surface of the first guide plate 120 and the concave surface of the second guide plate 130 are used together to guide the air outlet airflow. Specifically, the airflow blown out from the volute duct 170 flows between the outer convex surface of the first guide plate 120 and the inner concave surface of the second guide plate 130. The outer convex surface of the first guide plate 120 and the inner concave surface of the second guide plate 130 work together to make the airflow flow downwards at an angle in the first direction. During this process, a small amount of airflow may pass through the first overflow hole 121 on the first guide plate 120 and the second overflow hole 131 on the second guide plate 130. However, since the airflow direction is different from the opening direction of the first overflow hole 121 and the second overflow hole 131, this amount of airflow can be ignored. In this way, the first guide plate 120 and the second guide plate 130 simultaneously play the role of guiding the airflow, ensuring that the airflow flows downwards at an angle in the first direction, improving the accuracy of airflow guidance and enhancing the airflow guidance effect.

[0058] When the air conditioner 100 is in cooling mode, the first guide plate 120 and the second guide plate 130 are both rotated to a position between the middle position and the right limit position. At this time, the concave surfaces of the first guide plate 120 and the second guide plate 130 are both facing upwards. The concave surface of the first guide plate 120, the convex surface of the first guide plate 120, and the concave surface of the second guide plate 130 are used together to guide the airflow. Specifically, part of the airflow blowing out from the volute duct 170 flows downwards along the second direction along the concave surface of the first guide plate 120, while the other part flows between the convex surface of the first guide plate 120 and the concave surface of the second guide plate 130. The convex surface of the first guide plate 120 and the concave surface of the second guide plate 130 work together to ensure that the airflow flows downwards along the second direction. During this process, a small amount of airflow may pass through the first overflow hole 121 on the first guide plate 120 and the second overflow hole 131 on the second guide plate 130. However, since the airflow direction is different from the opening direction of the first overflow hole 121 and the second overflow hole 131, this small amount of airflow can be ignored. In this way, the first guide plate 120 and the second guide plate 130 simultaneously play the role of guiding the airflow, ensuring that the airflow flows downwards along the second direction, improving the accuracy of airflow guidance and enhancing the airflow guidance effect.

[0059] When the air conditioner 100 is in constant temperature mode, the first guide plate 120 and the second guide plate 130 are both rotated to a position between the middle position and the right extreme position. At this time, the concave surfaces of the first guide plate 120 and the second guide plate 130 are both set to the upward angle. The concave surface of the first guide plate 120, the convex surface of the first guide plate 120, and the concave surface of the second guide plate 130 are used together to guide the airflow. Specifically, part of the airflow blown out from the volute duct 170 flows downwards along a third direction along the concave surface of the first guide plate 120, while the other part flows between the convex surface of the first guide plate 120 and the concave surface of the second guide plate 130. The convex surface of the first guide plate 120 and the concave surface of the second guide plate 130 work together to ensure that the airflow flows downwards along a third direction. During this process, a small amount of airflow may pass through the first overflow hole 121 on the first guide plate 120 and the second overflow hole 131 on the second guide plate 130. However, since the airflow direction is different from the opening direction of the first overflow hole 121 and the second overflow hole 131, this small amount of airflow can be ignored. In this way, the first guide plate 120 and the second guide plate 130 simultaneously play the role of guiding the airflow, ensuring that the airflow flows downwards along a third direction, improving the accuracy of airflow guidance and enhancing the airflow guidance effect.

[0060] When the air conditioner 100 is in dual-zone air supply mode, the first guide plate 120 rotates to the right limit position and the second guide plate 130 rotates to the left limit position. At this time, the outer convex surfaces of the first guide plate 120 and the second guide plate 130 are arranged opposite to each other. The outer convex surface of the first guide plate 120, the inner concave surface of the second guide plate 130, and the outer convex surface of the second guide plate 130 are used together to guide the airflow. Specifically, part of the airflow blowing out from the volute duct 170 flows in one direction along the concave surface of the second guide plate 130, while the other part flows between the convex surfaces of the first guide plate 120 and the second guide plate 130. The convex surfaces of the first guide plate 120 and the second guide plate 130 work together to cause the airflow to flow in a completely different direction. During this process, a small amount of airflow may pass through the first overflow hole 121 on the first guide plate 120 and the second overflow hole 131 on the second guide plate 130. However, since the airflow direction is different from the opening direction of the first overflow hole 121 and the second overflow hole 131, this small amount of airflow can be ignored. In this way, the first guide plate 120 and the second guide plate 130 simultaneously function as air guides, allowing the airflow to be blown out from two different directions at the same time, improving the accuracy and effectiveness of airflow guidance.

[0061] In the air conditioner 100 of this embodiment, a first guide plate 120 and a second guide plate 130 are spaced apart and rotatably installed inside a housing 110. The first guide plate 120 has a first rotation axis, and its perpendicular bisector intersects with the first guide plate 120 at a first intersection point. The second guide plate 130 has a second rotation axis, and its perpendicular bisector intersects with the second guide plate 130 at a second intersection point. The first guide plate 120 and the second guide plate 130 satisfy the following relationship: L = x(M+N); 1.1 ≤ x ≤ 1.7; where L is the distance between the first and second rotation axes, M is the distance between the first rotation axis and the first intersection point, N is the distance between the second rotation axis and the second intersection point, and x is a preset coefficient. Compared with the prior art, the air conditioner 100 provided by the present invention adopts a first guide plate 120 and a second guide plate 130 that satisfy a certain positional relationship. Therefore, it can prevent interference when the two guide plates rotate while minimizing the black gap generated when the two guide plates are closed, thereby enhancing the air guiding effect and ensuring the aesthetics of the air conditioner 100.

[0062] 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 invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
