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 higher and higher requirements for the functionality of air conditioners. Current air conditioners have a single air outlet method, only capable of simple heating or cooling functions, failing to meet users' special needs (such as zero-wind-feel airflow). Furthermore, the deflector plate easily obstructs the airflow outwards during rotation, affecting the air volume and resulting in poor air guiding effect, thus impacting the user experience. Summary of the Invention

[0003] The problem solved by this invention is how to achieve different air outlet methods to meet user needs, and avoid the airflow being blocked outward by the deflector plate, so as to ensure air volume and improve the air guiding effect.

[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 and a deflector plate. The housing includes a middle frame and a front panel, with the front panel mounted on the outer side of the middle frame. A panel airflow channel is formed between the front panel and the middle frame. At least a portion of the front panel has a plurality of first micro-holes communicating with the panel airflow channel. The housing has an air outlet, and a volute airflow channel with an outlet is provided inside the housing. The rotation center of the deflector plate is located between the air outlet and the outlet. A limiting structure is provided inside the housing to abut against the end of the deflector plate, thereby defining the initial and final points of the deflector plate's rotation. The end of the deflector plate includes a head end and a tail end, which move along the trajectory of the head end during the rotation of the deflector plate from the initial point to the final point. Compared with the prior art, the air conditioner provided by this invention, due to the panel airflow channel located between the front panel and the middle frame and the deflector plate whose tail moves along the trajectory of the head end, can maximize the rotation angle of the deflector plate within a limited space while avoiding interference and ensuring the reliability of the deflector plate's rotation.

[0006] Furthermore, the deflector plate includes a first deflector plate and a second deflector plate. The first deflector plate has a first rotation center, and the second deflector plate has a second rotation center. Both the first rotation center and the second rotation center are located between the air outlet and the air outlet. The end of the first deflector plate includes a first head end and a first tail end that are disposed opposite to each other, and the end of the second deflector plate includes a second head end and a second tail end that are disposed opposite to each other. During the process of the first deflector plate rotating from the initial point to the end point, the first tail end moves along the motion trajectory of the first head end, and / or, during the process of the second deflector plate rotating from the initial point to the end point, the second tail end moves along the motion trajectory of the second head end.

[0007] Furthermore, during the rotation of the first drainage plate from the initial point to the final point, the line connecting the first head end and the first rotation center sweeps through the first sector area, and the line connecting the first tail end and the first rotation center sweeps through the second sector area. A first perpendicular bisector is drawn on the line connecting the initial point and the final point of the rotation of the first drainage plate, and the first sector area and the second sector area are symmetrically arranged about the first perpendicular bisector; and / or, during the rotation of the second drainage plate from the initial point to the final point, the line connecting the second head end and the second rotation center sweeps through the third sector area, and the line connecting the second tail end and the second rotation center sweeps through the fourth sector area. A second perpendicular bisector is drawn on the line connecting the initial point and the final point of the second drainage plate, and the third sector area and the fourth sector area are symmetrically arranged about the second perpendicular bisector.

[0008] Furthermore, the first rotation center and the second rotation center are not on the same vertical line and are not on the same horizontal line. Both the first drainage plate and the second drainage plate have convex surfaces. The cross-section of the convex surface is set in an arc, and the central angle of the arc formed by the convex surface is in the range of 130 degrees to 160 degrees.

[0009] Furthermore, a mounting bracket is provided on the middle frame, and both the first and second drainage plates can be rotatably mounted on the mounting bracket. A limiting structure is provided on the mounting bracket. The limiting structure includes a first limiting platform and a second limiting platform arranged at intervals. The first limiting platform is used to limit the initial point and the end point of the rotation of the first drainage plate, and the second limiting platform is used to limit the initial point and the end point of the rotation of the second drainage plate.

[0010] Furthermore, the first guide plate is densely covered with multiple second micro-holes, and the second guide plate is densely covered with multiple third micro-holes. Both the second and third micro-holes are used to supply airflow to blow outwards.

[0011] Furthermore, the opening direction of the second micropore is perpendicular to the surface of the first drainage plate, and the opening direction of the third micropore is perpendicular to the surface of the second drainage plate; or, the opening direction of the second micropore is perpendicular to the line connecting the two ends of the first drainage plate, and the opening direction of the third micropore is perpendicular to the line connecting the two ends of the second drainage plate.

[0012] Furthermore, a first line is formed between the first rotation center and the bottom end of the front panel, and a second line is formed between the second rotation center and the bottom end of the front panel. A preset angle is formed between the first line and the second line, and the preset angle ranges from 10 degrees to 20 degrees.

[0013] Furthermore, the housing also includes an end cover plate, which is disposed on the end side of the middle frame and is detachably connected to the middle frame. The side projection of the drainage plate during rotation is always located within the side projection outline of the end cover plate.

[0014] Furthermore, the panel airflow channel includes an interconnected clearance section and a converging section. The converging section is located above the clearance section. The clearance section is used to allow the deflector plate to rotate and also to allow the exhaust airflow to flow into the converging section. The converging section is used to gather the exhaust airflow. The width of the converging section ranges from 5 mm to 10 mm. Attached Figure Description

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 maximizes the rotation angle of the air intake plate within a limited space while avoiding interference, ensuring the reliability of the air intake plate's rotation.

[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, an air deflector plate, a first drive motor 140, and a second drive motor 150. The housing 110 includes a middle frame 160 and a front panel 170. The front panel 170 is used to shield the front of the middle frame 160 to improve the overall aesthetics of the air conditioner 100. The front panel 170 is mounted on the outside of the middle frame 160, and a panel airflow channel 180 is formed between the front panel 170 and the middle frame 160. At least a portion of the front panel 170 is provided with a plurality of first micro-holes 171, which are connected to the panel airflow channel 180. The airflow in the panel airflow channel 180 can flow outward through the plurality of first micro-holes 171 at the same time. Since the diameter of the first micro-holes 171 is small, the airflow volume and velocity of the airflow flowing out from the first micro-holes 171 are extremely low. The airflow flows out slowly from the first micro-holes 171 on the front panel 170 to achieve the zero-wind-feel airflow function of the air conditioner 100, realize different airflow modes, and meet user needs.

[0030] Furthermore, the housing 110 has an air outlet 111, and a volute duct 113 with an outlet 112 is provided inside the housing 110. The volute duct 113 is used to install a cross-flow fan 114. The cross-flow fan 114 installed in the volute duct 113 can generate negative pressure to drive the airflow along the volute duct 113 and blow it out through the outlet 112. A guide plate is provided outside the outlet 112 to guide the airflow blowing out from the outlet 112, thereby adjusting the airflow direction and causing the airflow to blow into the room from the air outlet 111, thus achieving the temperature control function. Specifically, the guide plate has a rotation center located between the air outlet 111 and the outlet 112 to ensure the air guiding effect.

[0031] It should be noted that a limiting structure 115 is provided inside the housing 110. The limiting structure 115 is used to abut against the end of the guide plate to limit the initial and final points of the guide plate's rotation. Specifically, the end of the guide plate includes a head end and a tail end arranged opposite each other. During the process of the guide plate rotating from the initial point to the tail end, the tail end moves along the movement trajectory of the head end to prevent the guide plate from blocking the airflow outward, ensuring the airflow volume and improving the air guiding effect. Furthermore, this design of the guide plate's movement trajectory allows the guide plate to form a perfect circle. Within the same space, this design allows the guide plate to rotate at a larger angle, and by limiting the rotation trajectory, the guide plate is less likely to interfere with adjacent structures, ensuring its rotation process is stable and reliable.

[0032] The airflow guide plate includes a first airflow guide plate 120 and a second airflow guide plate 130. The first airflow guide plate 120 has a first rotation center and is rotatable around the first rotation center. The second airflow guide plate 130 has a second rotation center and is rotatable around the second rotation center. Both the first and second rotation centers are located between the air outlet 111 and the outlet 112 to ensure the airflow guiding effect. The limiting structure 115 is used to abut against the ends of the first airflow guide plate 120 and the second airflow guide plate 130 to limit the initial and final points of rotation of the first airflow guide plate 120 and the second airflow guide plate 130, preventing the first airflow guide plate 120 and the second airflow guide plate 130 from rotating excessively.

[0033] In this embodiment, both the first drainage plate 120 and the second drainage plate 130 are arc-shaped. The end of the first drainage plate 120 includes a first head end 121 and a first end end 122 that are disposed opposite to each other in the width direction of the first drainage plate 120. The end of the second drainage plate 130 includes a second head end 131 and a second end end 132 that are disposed opposite to each other in the width direction of the second drainage plate 130. During the rotation of the first guide plate 120 from the initial point to the end point, the first end 122 moves along the movement trajectory of the first head 121, that is, the distance between the first head 121 and the first rotation center is equal to the distance between the first end 122 and the first rotation center. This can effectively improve the stability of the first guide plate 120 during rotation and prevent the first guide plate 120 from affecting the air outlet effect; and / or, during the rotation of the second guide plate 130 from the initial point to the end point, the second end 132 moves along the movement trajectory of the second head 131, that is, the distance between the second head 131 and the second rotation center is equal to the distance between the second end 132 and the second rotation center. This can effectively improve the stability of the second guide plate 130 during rotation and prevent the second guide plate 130 from affecting the air outlet effect.

[0034] Specifically, during the rotation of the first drainage plate 120 from the initial point to the end point, the line connecting the first head 121 and the first rotation center sweeps through the first sector area, and the line connecting the first tail 122 and the first rotation center sweeps through the second sector area. A first perpendicular bisector is drawn on the line connecting the initial point and the end point of the rotation of the first drainage plate 120, and the first sector area and the second sector area are symmetrically arranged about the first perpendicular bisector. And / or, during the rotation of the second drainage plate 130 from the initial point to the end point, the line connecting the second head 131 and the second rotation center sweeps through the third sector area, and the line connecting the second tail 132 and the second rotation center sweeps through the fourth sector area. A second perpendicular bisector is drawn on the line connecting the initial point and the end point of the second drainage plate 130, and the third sector area and the fourth sector area are symmetrically arranged about the second perpendicular bisector.

[0035] Furthermore, the first and second air intake plates 120 and 130, which are arranged in an arc shape, have low wind resistance and good air guiding effect. Both the concave and convex surfaces of the arc-shaped plates can guide air, thereby further improving the diversity of air outlet modes of the air conditioner 100.

[0036] It is worth noting that the housing 110 also includes an end cover plate 116, which covers the end side of the middle frame 160 and is detachably connected to the middle frame 160. The end cover plate 116 is used to shield the end side of the middle frame 160 to improve the overall aesthetics of the air conditioner 100. The side projection of the air guide plate (including the first air guide plate 120 and the second air guide plate 130) during rotation is always within the side projection outline of the end cover plate 116, so that the air guide plate can rotate at a larger angle inside the housing 110, that is, a larger limit rotation angle. Therefore, it can provide more diverse air guiding angles, improve the diversity of air outlet modes of the air conditioner 100, and in this way, the space occupied by the air guide plate rotation is small, making it easier to rotate within the housing 110 and less prone to interference.

[0037] In this embodiment, the air conditioner 100 is designed with a larger air outlet 111 to accommodate the dual guides (first air guide plate 120 and second air guide plate 130). The air outlet 111, together with the two air guide plates with larger rotation angles, can provide users with a more diverse airflow experience. In addition, the design of the air guide plates into a double-cylinder arc shape enhances the aesthetics of the air conditioner 100 and makes it more technologically advanced.

[0038] In this embodiment, there are two end cover plates 116. The two end cover plates 116 are disposed opposite to each other at both ends of the middle frame 160. The two end cover plates 116 are disposed in the same position, and the outer contour lines of the two end cover plates 116 also fit each other. The first guide plate 120 and the second guide plate 130 rotate between the two end cover plates 116 to further prevent the first guide plate 120 and the second guide plate 130 from blocking the airflow and improve the air guiding effect.

[0039] It should be noted that both the first drive motor 140 and the second drive motor 150 are mounted on the housing 110. The first drive motor 140 is connected to the first air intake plate 120 and is used to drive the first air intake plate 120 to rotate. The second drive motor 150 is connected to the second air intake plate 130 and is used to drive the second air intake plate 130 to rotate. Specifically, the first drive motor 140 and the second drive motor 150 operate independently, that is, the operation of the first air intake plate 120 and the operation of the second air intake plate 130 do not interfere with each other. Users can operate only the first air intake plate 120 without operating the second air intake plate 130, or only operate the second air intake plate 130 without operating the first air intake plate 120, thereby improving the diversity of air outlet modes of the air conditioner 100.

[0040] In this embodiment, the first rotation center and the second rotation center are not on the same vertical line or the same horizontal line; that is, the line connecting the first rotation center and the second rotation center is inclined. Specifically, both the first drainage plate 120 and the second drainage plate 130 have convex surfaces, the cross-section of which is arc-shaped, and the central angle of the arc formed by the convex surface ranges from 130 degrees to 160 degrees. Further, the first rotation center is the center of the arc formed by the convex surface of the first drainage plate 120, to increase the rotatable angle of the first drainage plate 120; the second rotation center is the center of the arc formed by the convex surface of the second drainage plate 130, to increase the rotatable angle of the second drainage plate 130.

[0041] In this embodiment, a mounting bracket 161 is provided on the middle frame 160, and a limiting structure 115 is provided on the mounting bracket 161. The first guide plate 120 and the second guide plate 130 can be rotatably mounted on the mounting bracket 161. The mounting bracket 161 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 mounting bracket 161 to realize the function of guiding the airflow.

[0042] The limiting structure 115 includes a first limiting platform 1151 and a second limiting platform 1152 spaced apart. The first limiting platform 1151 is used to limit the initial point and the final point of rotation of the first drainage plate 120. When the first drainage plate 120 rotates to the left extreme position, one side of the first limiting platform 1151 abuts against the first end 122 of the first drainage plate 120 at the initial point of rotation of the first drainage plate 120; when the first drainage plate 120 rotates to the right extreme position, the other side of the first limiting platform 1151 abuts against the first head 121 of the first drainage plate 120 at the final point of rotation of the first drainage plate 120. The second limiting platform 1152 is used to limit the initial point and the end point of the rotation of the second drainage plate 130. When the second drainage plate 130 rotates to the left limit position, one side of the second limiting platform 1152 abuts against the second end 132 of the second drainage plate 130 at the initial point of the rotation of the second drainage plate 130. When the second drainage plate 130 rotates to the right limit position, the other side of the second limiting platform 1152 abuts against the second head 131 of the second drainage plate 130 at the end point of the rotation of the second drainage plate 130.

[0043] In this embodiment, the first air intake plate 120 is densely provided with a plurality of second micro-holes 123, and the second air intake plate 130 is densely provided with a plurality of third micro-holes 133. Both the second micro-holes 123 and the third micro-holes 133 are used to supply airflow to be blown outward. When the air conditioner 100 is in a zero-wind-feel airflow state, the airflow can flow outward through the plurality of second micro-holes 123 and the plurality of third micro-holes 133 simultaneously. Since the diameters of the second micro-holes 123 and the third micro-holes 133 are small, the airflow volume and velocity of the airflow flowing out from the second micro-holes 123 and the third micro-holes 133 are extremely low. The airflow slowly flows out from the second micro-holes 123 on the first air intake plate 120 and the third micro-holes 133 on the second air intake plate 130 to achieve the zero-wind-feel airflow function of the air conditioner 100 and ensure the heat exchange effect during zero-wind-feel airflow.

[0044] In this embodiment, the opening direction of the second micro-hole 123 is perpendicular to the surface of the first drainage plate 120. Since the first drainage plate 120 is arc-shaped, the opening directions of the multiple second micro-holes 123 on the first drainage plate 120 are not entirely the same. The opening direction of the third micro-hole 133 is perpendicular to the surface of the second drainage plate 130. Since the second drainage plate 130 is arc-shaped, the opening directions of the multiple third micro-holes 133 on the second drainage plate 130 are not entirely the same. However, this is not the only embodiment. In other embodiments, the opening direction of the second micro-hole 123 is perpendicular to the line connecting the two ends of the first drainage plate 120 (the line connecting the first head end 121 and the first tail end 122), in which case the opening directions of the multiple second micro-holes 123 are the same; the opening direction of the third micro-hole 133 is perpendicular to the line connecting the two ends of the second drainage plate 130 (the line connecting the second head end 131 and the second tail end 132), in which case the opening directions of the multiple third micro-holes 133 are the same.

[0045] Furthermore, a first line is formed between the first rotation center and the bottom end of the front panel 170, and a second line is formed between the second rotation center and the bottom end of the front panel 170. A preset angle is formed between the first and second lines, with the preset angle ranging from 10 degrees to 20 degrees. A reasonable preset angle ensures that the airflow from the first and second airflow guide plates 120 and 130 can smoothly flow into the panel airflow channel 180, reducing air resistance and preventing the airflow from escaping between the bottom end of the front panel 170 and the first airflow guide plate 120. For ease of understanding, the preset angle is denoted as A.

[0046] In this embodiment, the preset included angle is 14 degrees, but it is not limited to this. In other embodiments, the preset included angle can be 10 degrees or 20 degrees. The size of the preset included angle is not specifically limited.

[0047] The panel airflow channel 180 includes an interconnected bypass section 181 and a concentrating section 182. The concentrating section 182 is located above the bypass section 181. The exhaust airflow, guided by the first guide plate 120 and the second guide plate 130, first enters the bypass section 181 and then flows into the concentrating section 182. The bypass section 181 allows the first guide plate 120 to rotate, preventing interference with it. The bypass section 181 also allows the exhaust airflow to flow into the concentrating section 182, increasing the air pressure within it. The concentrating section 182 gathers the exhaust airflow. When the air pressure within the concentrating section 182 increases to a certain level, the exhaust airflow overflows through the first micro-hole 171 on the front panel 170 under the influence of the air pressure, increasing the exhaust velocity and volume, and ensuring effective heat exchange during zero-wind-feel exhaust.

[0048] Specifically, the width of the air-gathering section 182 ranges from 5 mm to 10 mm. A reasonable width of the air-gathering section 182 ensures that the air pressure within it remains below a certain level, preventing excessive air pressure from causing an excessively fast airflow rate, thus guaranteeing a zero-wind-feel effect. For ease of understanding, the width of the air-gathering section 182 is denoted as B.

[0049] In this embodiment, the width of the wind-gathering section 182 is 8 mm, but it is not limited to this. In other embodiments, the width of the wind-gathering section 182 can be 5 mm or 10 mm. The width of the wind-gathering section 182 is not specifically limited.

[0050] 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.

[0051] 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'.

[0052] When the air conditioner 100 is in zero-wind mode, the first deflector plate 120 and the second deflector plate 130 are both rotated to the middle position. At this time, the concave surfaces of the first deflector plate 120 and the second deflector plate 130 are set facing the outlet 112 to play the role of scooping the air and guiding the airflow towards the air flow channel 180 of the panel. Specifically, when the airflow from outlet 112 reaches the concave surfaces of the first and second guide plates 120 and 130, a portion of the airflow flows out directly through the second micro-hole 123 on the first guide plate 120 and the third micro-hole 133 on the second guide plate 130, achieving zero-wind-feel airflow in the area of ​​the first and second guide plates 120 and 130. The other portion of the airflow, guided by the concave surfaces of the first and second guide plates 120 and 130, flows into the panel airflow channel 180 and flows out through the first micro-hole 171 on the front panel 170, achieving zero-wind-feel airflow in the area of ​​the front panel 170. This effectively increases the airflow volume for zero-wind-feel airflow, ensuring heat exchange efficiency.

[0053] When the air conditioner 100 is in enhanced heating mode, both the first deflector plate 120 and the second deflector plate 130 are rotated to the left limit position. At this time, the outer convex surface of the first deflector plate 120 is set to face the panel airflow channel 180 to block the panel airflow channel 180 and prevent the airflow from flowing into the panel airflow channel 180. The outer convex surface of the second deflector plate 130 is set to face the first deflector plate 120 to avoid guiding the airflow to the area where the first deflector plate 120 is located. Specifically, part of the airflow blowing out from outlet 112 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 second micro-hole 123 on the first guide plate 120 and the third micro-hole 133 on the second guide plate 130. However, since the airflow direction is different from the opening direction of the second micro-hole 123 and the third micro-hole 133, 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 air guidance, and enhancing the air guidance effect.

[0054] When the air conditioner 100 is in normal heating mode, both the first deflector plate 120 and the second deflector plate 130 are rotated to the right limit position. At this time, the concave surface of the first deflector plate 120 is set directly opposite the air flow channel 180 of the panel, and the concave surface of the second deflector plate 130 is set directly opposite the first deflector plate 120. The convex surface of the first deflector plate 120 and the concave surface of the second deflector plate 130 are used together to guide the airflow. Specifically, the airflow blown out from outlet 112 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 second micro-hole 123 on the first guide plate 120 and the third micro-hole 133 on the second guide plate 130. However, since the airflow direction is different from the opening direction of the second micro-hole 123 and the third micro-hole 133, 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 at an angle in the first direction, improving the accuracy of airflow guidance and enhancing the airflow guidance effect.

[0055] When the air conditioner 100 is in cooling mode, both the first deflector plate 120 and the second deflector plate 130 rotate to a position between the middle position and the right extreme position. At this time, the concave surfaces of the first deflector plate 120 and the second deflector plate 130 are both facing upwards. The concave surface of the first deflector plate 120, the convex surface of the first deflector plate 120, and the concave surface of the second deflector plate 130 are used together to guide the airflow. Specifically, part of the airflow blowing out from outlet 112 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 second micro-hole 123 on the first guide plate 120 and the third micro-hole 133 on the second guide plate 130. However, since the airflow direction is different from the opening direction of the second micro-hole 123 and the third micro-hole 133, 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 downwards along the second direction, improving the accuracy of air guidance and enhancing the air guidance effect.

[0056] When the air conditioner 100 is in constant temperature mode, the first air intake plate 120 and the second air intake 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 air intake plate 120 and the second air intake plate 130 are both set to the upward angle. The concave surface of the first air intake plate 120, the convex surface of the first air intake plate 120, and the concave surface of the second air intake plate 130 are used together to guide the airflow. Specifically, part of the airflow blown out from outlet 112 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 second micro-hole 123 on the first guide plate 120 and the third micro-hole 133 on the second guide plate 130. However, since the airflow direction is different from the opening direction of the second micro-hole 123 and the third micro-hole 133, 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 downwards along a third direction, improving the accuracy of air guidance and enhancing the air guidance effect.

[0057] When the air conditioner 100 is in dual-zone air supply mode, the first air intake plate 120 rotates to the right limit position and the second air intake plate 130 rotates to the left limit position. At this time, the outer convex surfaces of the first air intake plate 120 and the second air intake plate 130 are arranged opposite to each other. The outer convex surface of the first air intake plate 120, the inner concave surface of the second air intake plate 130, and the outer convex surface of the second air intake plate 130 are used together to guide the airflow. Specifically, part of the airflow blowing out from outlet 112 flows in one direction along the concave surface of the second guide plate 130, while the other part flows into the space between the outer convex surfaces of the first guide plate 120 and the second guide plate 130. The outer 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 second micro-hole 123 on the first guide plate 120 and the third micro-hole 133 on the second guide plate 130. However, since the airflow direction is different from the opening direction of the second and third micro-holes 123, this small amount of airflow can be ignored. In this way, the first guide plate 120 and the second guide plate 130 simultaneously act 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.

A limiting structure 115 is provided inside the housing 110, which abuts against the end of the deflector plate to limit the initial and final points of the deflector plate's rotation. The end of the deflector plate includes a head end and a tail end, which are arranged opposite each other. During the process of the deflector plate rotating from the initial point to the final point, the tail end moves along the movement trajectory of the head end. Compared with the prior art, the air conditioner 100 provided by the present invention adopts a panel airflow channel 180 disposed between the front panel 170 and the middle frame 160 and a deflector plate that moves along the movement trajectory of the head end. Therefore, it can maximize the rotation angle of the deflector plate within a limited space, while avoiding interference and ensuring the reliability of the deflector plate rotation.
