[0043] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] In the description of the present utility model, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] The wind deflector 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0047] like Figure 6-Figure 11 As shown, the air guide plate 10 according to the embodiment of the utility model includes: a first grid layer 2 and a cyclone 1.

[0048] Specifically, refer to Figure 6-Figure 11The first grille layer 2 includes a first plate body 21, and a plurality of first micropores 211 are provided on the first plate body 21; the cyclone 1 is provided on one side of the first grille layer 2 in the thickness direction and is an integral part with the first grille layer 2, and the cyclone 1 is used to rotate the airflow passing through the cyclone 1. It should be noted that the air conditioner 100 has an air outlet 301, and when the air guide plate 10 closes the air outlet 301, the airflow can flow out of the air outlet 301 through the first micropores 211 and the cyclone 1, thereby achieving windless air outlet of the air conditioner 100.

[0049] It can be understood that part of the airflow passing through the air guide plate 10 will change its flow direction and form a vortex under the action of the cyclone 1, so that the airflow entering the air guide plate 10 and the air outlet direction leaving the air guide plate 10 are inconsistent, and the airflow is converted from straight wind to vortex wind, thereby improving the turbulent state of the airflow during the flow process. At the same time, it can reduce the airflow velocity and improve the smoothness of the airflow flow, so that the airflow will not blow directly to the user after passing through the air guide plate 10, thereby improving the comfort of the air outlet 301.

[0050] Since the first plate body 21 has the first microhole 211, the airflow can not only flow out of the air guide plate 10 through the cyclone 1, but also flow out of the air guide plate 10 directly through the first microhole 211, thereby increasing the air outlet area, thereby increasing the air outlet volume, and improving the air outlet effect. Among them, the first microhole 211 can also play the effect of breaking up the airflow, thereby also improving the turbulent state of the airflow during the flow process, and at the same time can reduce the airflow velocity, improve the flexibility of the airflow flow, and improve the comfort.

[0051] Furthermore, the cyclone 1 and the first grid layer 2 are an integrated part, thereby improving the overall strength of the air guide plate 10 and improving the durability of the air guide plate 10 .

[0052] The cross-sectional shape of the first micropore 211 can be circular, triangular, square or honeycomb, etc. The specific shape is not limited here. Figure 8 and Fig. 9 In the example shown, the first micropore 211 is a round hole with a circular cross section, which has a simple structure and is easy to process. Further, a plurality of first micropores 211 can be arranged in an array on the first plate body 21, thereby arranging as many ventilation holes as possible on the first plate body 21 under the premise of ensuring a certain structural strength of the first plate body 21, while not affecting the dispersion of the airflow, and ensuring sufficient ventilation, thereby ensuring the air output.

[0053] According to the air guide plate 10 of the embodiment of the utility model, a plurality of first micropores 211 spaced apart are provided on the first plate body 21, and the cyclone 1 is provided on one side of the thickness direction of the first grid layer 2, and the cyclone 1 is used to rotate the airflow passing through the cyclone 1. As a result, the airflow can not only flow out of the air guide plate 10 through the cyclone 1, but also directly flow out of the air guide plate 10 through the first micropores 211, thereby increasing the air outlet area, thereby increasing the air outlet volume, and improving the air outlet effect.

[0054] In some embodiments of the present invention, Figure 6 , Figure 7 , Fig.10 and Fig.11 As shown, the air guide plate 10 further includes: a second grille layer 3, the second grille layer 3 includes a second plate body 31, a plurality of spaced second micropores 311 are provided on the second plate body 31, and the second grille layer 3 and the first grille layer 2 are stacked.

[0055] It can be understood that the second grille layer 3 is arranged on one side of the thickness direction of the first grille layer 2, and the airflow passes through the first micropores 211 and the second micropores 311 to break up the airflow, thereby further improving the turbulent state of the airflow during the flow process, while being able to reduce the airflow velocity, improve the smoothness of the airflow flow, and improve comfort.

[0056] It should be noted that the cross-sectional shape of the second micropore 311 can be circular, triangular, square or honeycomb, etc., and the specific shape is not limited here. Fig.10 and Fig.11 In the example shown, the second micropores 311 are round holes with a circular cross section, simple in structure and easy to process. Further, a plurality of second micropores 311 can be arranged in an array on the second plate 31, so that as many ventilation holes as possible can be arranged on the second plate 31 under the premise of ensuring a certain structural strength of the second plate 31, and sufficient ventilation can be ensured without affecting the dispersion of the airflow, thereby ensuring the air volume.

[0057] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, the cyclone 1 is located between the first grid layer 2 and the second grid layer 3. Therefore, the cyclone 1 can be protected by the first grid layer 2 and the second grid layer 3, thereby increasing the service life of the cyclone 1.

[0058] When the air conditioner 100 is blowing out wind without a sense of wind, part of the airflow can be initially dispersed through one of the first grille layer 2 and the second grille layer 3, and then rotated through the cyclone 1. After the airflow is transformed from straight wind to swirl wind, it will pass through the second grille layer 3 and the other of the first grille layer 2 to be dispersed and refined again and form a dispersed airflow to blow out the air outlet 301, which can further improve the turbulent state of the airflow during the flow process, making the airflow flow softer, which is conducive to improving the windless air outlet effect of the air conditioner 100, and thus improving the user's comfort. Part of the airflow can be blown out of the air outlet 301 through the first micropores 211 and the second micropores 311 to form a dispersed airflow, thereby increasing the air volume and improving the air outlet effect.

[0059] In addition, the first grille layer 2 and the second grille layer 3 can also shield the cyclone 1, so that the cyclone 1 can be prevented from being directly exposed to the outside when the air guide plate 10 is rotated to any angle, thereby improving the appearance of the air conditioner 100.

[0060] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the cyclone 1 includes: a fixed part 11 and a cyclone body 12, the fixed part 11 is annular and connected to the first plate body 21, the annular space of the fixed part 11 is opposite to and connected to part of the first micropores 211; the cyclone body 12 is arranged in the fixed part 11 and connected to the inner peripheral wall of the fixed part 11.

[0061] It can be understood that the setting of the fixing portion 11 allows the cyclone body 12 to be fixed relative to the first plate body 21, and the annular space is relative to and connected with part of the first micropores 211, so that part of the airflow can enter the annular space through the first micropores 211, so that the airflow can be dispersed by the cyclone body 12 to achieve windless air discharge.

[0062] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the swirler body 12 includes a first swirl blade 121, and the first swirl blade 121 is arranged in a plurality along the circumferential direction of the fixed portion 11 at intervals. Each first swirl blade 121 extends along the radial direction of the fixed portion 11 and the radial outer end is connected to the inner circumferential wall of the fixed portion 11. Along the airflow direction, the first swirl blade 121 is inclined toward one of the circumferential directions of the fixed portion 11.

[0063] It can be understood that the inclined first swirl blade 121 can change the direction of the airflow, and can guide the airflow flowing into the cyclone 1 to flow out along the inclined direction of the first swirl blade. At the same time, multiple first swirl blades 121 are arranged at intervals along the circumferential direction of the fixed part 11. On the one hand, the airflow passing through the cyclone 1 can be cut, broken up and diverted by the first swirl blades 121, which can effectively reduce wind resistance and make the wind output softer. On the other hand, multiple inclined first swirl blades 121 arranged at intervals along the circumferential direction of the fixed part 11 can change the direction of the airflow flowing into the cyclone 1 and generate rotation, converting the airflow from straight wind to swirl wind, improving the turbulent state of the airflow during the flow process, reducing the airflow velocity, and improving the flexibility of the airflow flow, which is conducive to the airflow flowing out of the cyclone 1 to achieve a windless effect.

[0064] Among them, it should be noted that the cyclone 1 can realize the rotation of the airflow through a plurality of inclined first cyclone blades, without the need to set up an axial flow fan wheel, a fan wheel driving device for driving the axial flow fan wheel to rotate, or a gear rack mechanism for transmitting power and torque, which greatly simplifies the structure of the device for realizing the airflow rotation, thereby reducing the cost of the air conditioner 100 to achieve a windless effect.

[0065] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the swirler body 12 also includes: a fixing ring 123, a mounting portion 124 and a second swirl blade 122. The fixing ring 123 is arranged in the fixing portion 11 and is spaced apart from the fixing portion 11. The radial inner end of each first swirl blade 121 is connected to the outer peripheral wall of the fixing ring 123; the mounting portion 124 is arranged in the fixing ring 123 and is spaced apart from the fixing ring 123; the second swirl blade 122 is a plurality of second swirl blades 122 spaced apart along the circumferential direction of the fixing portion 11, each second swirl blade 122 extends along the radial direction of the fixing portion 11 and has a radial outer end connected to the inner peripheral wall of the fixing ring 123, and a radial inner end connected to the outer peripheral wall of the mounting portion 124. Along the airflow direction, the second swirl blade 122 is inclined toward one of the circumferential directions of the fixing portion 11.

[0066] The first swirl blade 121, the fixing ring 123, the second swirl blade 122 and the mounting portion 124 can be integrally formed or fixedly connected together by welding, bonding, crimping, etc. The fixing ring 123 is provided to facilitate connecting the first swirl blade 121 and the second swirl blade 122, and also plays the role of dividing and diverting the airflow, making the airflow softer.

[0067] It should be noted that if Figure 8 and Fig. 9In the example shown, the mounting portion 124 may be cylindrical, the fixing portion 11 and the fixing ring 123 may be arranged in a circular shape, and the center line of the mounting portion 124, the center line of the fixing ring 123 and the center line of the fixing portion 11 coincide with each other, so that the plurality of first swirl blades 121 and the second swirl blades 122 are arranged symmetrically in the center of the fixing portion 11, which is beneficial for the airflow passing through the swirler 1 to rotate around the center of the fixing portion 11.

[0068] It can be understood that the inclined second swirl blades 122 can change the direction of the airflow, and can guide the airflow flowing into the cyclone 1 to flow out along the inclined direction of the second swirl blade. At the same time, multiple second swirl blades 122 are arranged at intervals along the circumferential direction of the fixed part 11. On the one hand, the airflow passing through the cyclone 1 can be cut, broken up and diverted by the second swirl blades 122, which can effectively reduce wind resistance and make the wind output softer. On the other hand, multiple inclined second swirl blades 122 arranged at intervals along the circumferential direction of the fixed part 11 can change the direction of the airflow flowing into the cyclone 1 and generate rotation, converting the airflow from straight wind to swirl wind, further improving the turbulent state of the airflow during the flow process, making the airflow flow more flexible, and thus facilitating the airflow flowing out of the cyclone 1 to achieve a windless effect.

[0069] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the cyclones 1 are arranged in a plurality of intervals along the length direction of the first grid layer 2. This can increase the air flow of the cyclone 1, thereby improving the air outlet efficiency of the air conditioner 100. Figure 8 and Fig. 9 In the example shown, there are seven cyclones 1 correspondingly arranged at intervals along the length direction of the first grid layer 2, but the present invention is not limited thereto, and the number of cyclones 1 may be other numbers, such as 5, 6, 8 or 10.

[0070] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the inclination directions of the first swirl blade 121 and the second swirl blade 122 are the same or opposite; the first swirl blade 121 and the second swirl blade 122 can respectively guide the airflow flowing into the swirler 1 to flow out along the inclination directions of the first swirl blade 121 and the second swirl blade 122. The same inclination direction of the first swirl blade 121 and the second swirl blade 122 is conducive to the airflow passing through the swirler 1 to rotate in the same direction. When the inclination directions of the first swirl blade 121 and the second swirl blade 122 are opposite, the airflow flowing into the swirler 1 can be guided to flow out in opposite directions, which can further enhance the turbulent state of the airflow during the flow process, reduce the impact of the airflow, and further facilitate the airflow flowing out of the swirler 1 to achieve a windless effect.

[0071] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the inclination angles of the first swirl blade 121 and the second swirl blade 122 are the same or different; the inclination angles of the first swirl blade 121 and the second swirl blade 122 can be the same, which is convenient for processing and production. Of course, the inclination angles of the first swirl blade 121 and the second swirl blade 122 can also be different, which can respectively guide the airflow flowing into the swirler 1 to flow out along different inclination angles, further enhance the turbulent state of the airflow during the flow process, reduce the impact of the airflow, and thus help to ensure the windless effect.

[0072] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the first swirl blades 121 of at least two of the multiple swirlers 1 have the same or opposite inclination direction; the first swirl blades 121 of at least two of the multiple swirlers 1 have the same inclination direction, which is conducive to the airflows passing through different swirlers 1 to rotate in the same direction, and is easy to process. The first swirl blades 121 of at least two of the multiple swirlers 1 have opposite inclination directions, so that the airflows entering different swirlers 1 can be guided by the first swirl blades 121 to flow out in different directions and rotate in opposite directions, which can enhance the turbulent state of the airflow passing through the swirler 1, reduce the impact of the airflow, and further enhance the windless effect of the airflow flowing out of the swirler 1.

[0073] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the inclination direction of the second swirl blades 122 of at least two swirlers 1 among the multiple swirlers 1 is the same or opposite. The inclination direction of the second swirl blades 122 of at least two swirlers 1 among the multiple swirlers 1 is the same, which is conducive to the airflows passing through different swirlers 1 to rotate in the same direction and is convenient for processing. The inclination directions of the second swirl blades 122 of at least two swirlers 1 among the multiple swirlers 1 are opposite, so that the airflows entering different swirlers 1 can be guided by the second swirl blades 122 to flow out in different directions and rotate in opposite directions, which can enhance the turbulent state of the airflow flowing through the swirler 1, reduce the impact of the airflow, and further enhance the windless effect achieved by the airflow flowing out of the swirler 1.

[0074] The air conditioner 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0075] like Figure 1-Figure 5As shown, the air conditioner 100 according to the embodiment of the utility model includes: a shell 30 and the above-mentioned air guide plate 10, the shell 30 has an air outlet 301; the air guide plate 10 is rotatably arranged at the air outlet 301 for opening or closing the air outlet 301.

[0076] It can be understood that the air outlet 301 can extend along the length direction of the shell 30 and be in a long strip shape. The long strip-shaped air outlet 301 can increase the air supply volume and air supply range. At this time, the air guide plate 10 extends along the length direction of the air outlet 301 and is in a long strip shape, so that the air guide plate 10 can be adapted to the air outlet 301, so that the air guide plate 10 can block the air outlet 301 when the air outlet 301 is closed.

[0077] At the same time, the rotation axis of the air guide plate 10 can extend along the length direction of the air outlet 301, so that the air guide plate 10 can close the air outlet 301 and can rotate smoothly to guide the air in the width direction of the air outlet 301. Figure 1-Figure 5 As shown, the air conditioner 100 is an on-hook unit, the air outlet 301 extends in the left-right direction of the air conditioner 100, and the air guide plate 10 guides air in the up-down direction. Specifically, a first rotating shaft 4 may be provided on the air guide plate 10, and an axial hole adapted to the first rotating shaft 4 may be provided at a corresponding position of the housing 30, so as to realize the rotation of the air guide plate 10 around an axis extending in the length direction of the air outlet 301.

[0078] The air deflector 10 may be connected to a first driving mechanism for driving the air deflector 10 to rotate. For example, the first driving mechanism may be a first driving motor. By arranging a first rotating shaft 4 on the air deflector 10 and connecting the driving shaft of the first driving motor to the first rotating shaft 4, the extension direction of the driving shaft axis of the first driving motor is the same as the extension direction of the first rotating shaft 4 of the air deflector 10, the first driving motor can drive the first rotating shaft 4 to rotate and drive the air deflector 10 to rotate.

[0079] According to the air conditioner 100 of the embodiment of the utility model, the above-mentioned air guide plate 10 is provided, a plurality of spaced first micro holes 211 are provided on the first plate body 21, and the cyclone 1 is provided on one side of the thickness direction of the first grille layer 2, and the cyclone 1 is used to rotate the airflow passing through the cyclone 1. Therefore, the airflow can not only flow out of the air guide plate 10 through the cyclone 1, but also directly flow out of the air guide plate 10 through the first micro holes 211, thereby increasing the air outlet area, thereby increasing the air outlet volume, and improving the air outlet effect.

[0080] In some embodiments of the present invention, Figure 1 , Figure 6 and Figure 7 As shown, when the air guide plate 10 closes the air outlet 301 , the first grid layer 2 is located on the inner side of the cyclone 1 or the first grid layer 2 is located on the outer side of the cyclone 1 .

[0081] It is understandable that if Figure 1 and Figure 6 As shown, the first grid layer 2 is located inside the cyclone 1, so that part of the airflow can be dispersed by the first micropores 211 and then dispersed by the cyclone 1, thereby enhancing the swirl effect of the airflow and improving comfort. Figure 1 and Figure 7 As shown, the first grid layer 2 is located outside the cyclone 1 , thereby improving the protection effect on the cyclone 1 .

[0082] In some embodiments of the present invention, Figure 1-Figure 5 As shown, the air conditioner 100 further includes: an inner air guide plate 20 , which is rotatably disposed at the air outlet 301 . When the air guide plate 10 closes the air outlet 301 , the inner air guide plate 20 is located on the inner side of the air guide plate 10 .

[0083] It is understandable that the rotation axis of the inner air guide plate 20 can extend along the length direction of the air outlet 301, so that the inner air guide plate 20 can rotate smoothly to guide the air in the width direction of the air outlet 301. Figure 1-Figure 5 As shown, the air conditioner 100 is an on-hook unit, the air outlet 301 extends in the left-right direction of the air conditioner 100, and the inner air guide plate 20 guides air in the up-down direction. Specifically, a second rotating shaft 201 may be provided on the inner air guide plate 20, and an axial hole adapted to the second rotating shaft 201 may be provided at a corresponding position of the housing 30, so as to realize the rotation of the inner air guide plate 20 around an axis extending in the length direction of the air outlet 301.

[0084] The inner air guide plate 20 may be connected to a second driving mechanism for driving the inner air guide plate 20 to rotate. For example, the second driving mechanism may be a second driving motor. By providing a second rotating shaft 201 on the inner air guide plate 20 and connecting the driving shaft of the second driving motor to the second rotating shaft 201, the extension direction of the driving shaft axis of the second driving motor is the same as the extension direction of the second rotating shaft 201 of the inner air guide plate 20, so that the second driving motor can drive the second rotating shaft 201 to rotate and drive the inner air guide plate 20 to rotate.

[0085] In some embodiments of the present invention, Figure 2 As shown, the air conditioner 100 has a windless air outlet state. In the windless air outlet state, the upper end of the air guide plate 10 is spaced apart from the air outlet 301 and the air outlet 301 is opened, the inner air guide plate 20 blocks or opens the air outlet area between the upper end of the air guide plate 10 and the upper edge of the air outlet 301, the air outlet end of the air guide plate 10 extends upwardly and obliquely, and the air outlet end of the inner air guide plate 20 extends downwardly and obliquely;

[0086] It can be understood that the inner air guide plate 20 blocks the air outlet area between the upper end of the air guide plate 10 and the upper edge of the air outlet 301, thereby preventing the air flow from directly flowing out from the air outlet area between the upper end of the air guide plate 10 and the upper edge of the air outlet 301, so that the air flow can flow out through the swirl effect of the air guide plate 10, thereby achieving windless air outlet.

[0087] Among them, in the windless air outlet state, the inner air guide plate 20 opens the air outlet area between the upper end of the air guide plate 10 and the upper edge of the air outlet 301, so that part of the air flow can flow out through the air outlet area between the upper end of the air guide plate 10 and the upper edge of the air outlet 301, and part of the air flow can flow out through the swirl effect of the air guide plate 10, thereby increasing the air outlet volume, achieving windless air outlet, and improving user comfort.

[0088] In some embodiments of the present invention, Figure 5 As shown, the air conditioner 100 has a heating air outlet state. In the heating air outlet state, the air guide plate 10 opens the air outlet 301, the inner air guide plate 20 and the air guide plate 10 are both located outside the air outlet 301, and are respectively located at the upper and lower sides of the air outlet 301, the air guide plate 10 is located at the lower side of the inner air guide plate 20, and the air outlet ends of the air guide plate 10 and the inner air guide plate 20 are both inclined and extended downward;

[0089] It can be understood that the air outlet ends of the air guide plate 10 and the inner air guide plate 20 are both inclined downwardly, so that the inner air guide plate 20 and the air guide plate 10 jointly block the airflow from flowing upward, thereby further guiding more airflow to flow downwardly. Since the density of hot air is low in the heating air outlet state, the hot air is easy to float upward, and guiding the airflow to flow downward can enhance the convection effect of the hot air, thereby improving the heating efficiency.

[0090] In addition, the air guide plate 10 opens the air outlet 301, thereby maximizing the air outlet area, thereby increasing the air volume, improving the air outlet effect in the heating air outlet state, and improving the heating efficiency.

[0091] In some embodiments of the present invention, Figure 3 As shown, the air conditioner 100 has a direct blowing prevention state. In the direct blowing prevention state, the upper end of the air guide plate 10 is spaced apart from the air outlet 301 and the air outlet 301 is opened, the inner air guide plate 20 is located at the lower end of the air outlet 301, the inner air guide plate 20 is located inside the air guide plate 10, and the air outlet ends of the air guide plate 10 and the inner air guide plate 20 are both extended upwardly at an angle;

[0092] It can be understood that the inner air guide plate 20 is located inside the air guide plate 10 and the air outlet ends of the air guide plate 10 and the inner air guide plate 20 are both inclined and extended upwards, thereby blocking the airflow from flowing downwards, so that more airflow flows upwards. Therefore, the air guide plate 10 and the inner air guide plate 20 can guide the airflow flowing out of the air outlet 301 upwards, so that the airflow is blown upwards, which can prevent the airflow from blowing directly downwards from the air outlet 301 to the user, and improve the comfort of the air outlet.

[0093] In some embodiments of the present invention, Figure 4 As shown, the air conditioner 100 has a default air outlet state. In the default air outlet state, the air guide plate 10 opens the air outlet 301, the air guide plate 10 is located at the lower side of the inner air guide plate 20, at least part of the inner air guide plate 20 is located inside the air outlet 301, and the air outlet ends of the air guide plate 10 and the inner air guide plate 20 extend downwardly at an angle. It should be noted that the default air outlet state can be a cooling air outlet state or a natural wind air outlet state, etc.

[0094] It is understandable that the air outlet 301 is opened by the air guide plate 10, so that the air outlet area is maximized, thereby increasing the air outlet volume and improving the air outlet effect in the default air outlet state. At the same time, at least part of the inner air guide plate 20 is located inside the air outlet 301, and the air outlet ends of the air guide plate 10 and the inner air guide plate 20 extend downwardly at an angle, so that the inclined extension direction of the inner air guide plate 20 and the extension direction of the air duct 302 are roughly parallel, so that the air flow can flow better, thereby improving the air outlet efficiency and air outlet volume in the default air outlet state, and improving the working efficiency of the air conditioner 100.
