Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and particularly relates to an air outlet module and an air conditioner. Background Art

[0002] When an air conditioner blows air directly to a user through an air outlet, the speed of the air outlet airflow is relatively high, which is likely to cause discomfort to the user. Therefore, traditional air conditioners usually have air outlet micro-holes on an air deflector or louvers and other air outlet structures, and these air outlet micro-holes are used to reduce the speed of the air outlet airflow. However, these air outlet micro-holes have a relatively large resistance to the airflow, which results in a reduction in the air outlet volume, and further leads to a decrease in the cooling or heating capacity of the air conditioner, making the comfort of the air conditioner's air outlet without wind feeling relatively poor. Summary of the Invention

[0010] Optionally, the range of the minimum diameter Dmin of each flow resistance segment is greater than or equal to 1 mm to 8 mm.

[0011] Optionally, two adjacent flow blocking segments on the flow blocking rod are detachably connected; alternatively, two adjacent flow blocking segments on the flow blocking rod are movably connected, so that the length of the flow blocking rod is adjustable.

[0012] Optionally, the air outlet module includes a plurality of the flow blocking layers, and the plurality of flow blocking layers are arranged at intervals along the air outlet direction of the air outlet frame.

[0013] Optionally, in two adjacent flow blocking layers, a plurality of flow blocking rods in one of the flow blocking layers are arranged in a staggered manner in the interlayer arrangement direction with respect to a plurality of flow blocking rods in the other flow blocking layer.

[0014] Optionally, in two adjacent flow blocking layers, at least one of the flow blocking layers is movable relative to the other flow blocking layer to adjust the distance between the two flow blocking layers.

[0015] Optionally, the range of the distance between two adjacent flow blocking layers is greater than or equal to 2 mm and less than or equal to 15 mm.

[0016] The present invention further provides an air conditioner, which includes a housing and an air outlet module; wherein, the housing is provided with an air outlet; the air outlet module is installed on the housing, and the air outlet module is adapted to block the air outlet. The air outlet module includes an air outlet frame and a flow blocking layer; the flow blocking layer is arranged on the air outlet frame, and the flow blocking layer includes a plurality of flow blocking rods extending along the length direction of the air outlet frame in a long strip shape, and the plurality of flow blocking rods are arranged at intervals along the width direction of the air outlet frame.

[0017] Optionally, the air outlet module is arranged on the front side of the air outlet, and the air outlet module is movable in the up and down direction to switch between a working position and an idle position, wherein: in the working position, the air outlet module is located on the front side of the air outlet; in the idle position, the air outlet module is hidden inside the housing.

Thus, the flow blocking rods of the flow blocking layer can block the air flow, so that the air flow forms a von Kármán vortex street around the flow blocking rods. The von Kármán vortex streets around adjacent flow blocking rods collide with each other to reduce the speed of the air flow, thereby realizing draft-free air output. After that, the draft-free air flow with reduced wind speed blows out from the air outlet gap of the flow blocking layer, and the air outlet resistance of the air outlet gap is small, so a large air flow rate can be passed, effectively increasing the draft-free air output of the air outlet module and improving the comfort of draft-free air output.

[0048] The realization of the object, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] It should be noted that if there are directional indications (such as up, down, left, right, front, back,...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0051] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0052] Figures 1 to 21 The accompanying drawings for the air outlet module 100 and the air conditioner 200 provided by the present invention are shown. The air outlet module 100 can be installed on the air outlet device to guide the airflow to blow out. The air outlet module 100 can increase the air volume of the draft-free air outlet to improve the comfort of the draft-free air outlet of the air conditioner. As for the type of the air outlet device, the air outlet device can be an air conditioner, an air machine, an air purifier or other air outlet devices; among them, the air conditioner can be any one of a wall-mounted air conditioner indoor unit, a floor-standing air conditioner indoor unit, a mobile air conditioner, and a ceiling-mounted air conditioner. Hereinafter, a floor-standing air conditioner will be mainly used as an example for introduction and description.

[0053] Please refer to Figures 1 to 3, in an embodiment of the air outlet module 100, the air outlet module 100 includes an air outlet frame 110 and a flow blocking layer 120; wherein, the flow blocking layer 120 is disposed on the air outlet frame 110, and the flow blocking layer 120 includes flow blocking rods 121 arranged at intervals in the width direction of the air outlet frame 110, and each flow blocking rod 121 is strip-shaped and extends along the length direction of the air outlet frame 110.

[0054] Specifically, the air outlet frame 110 can be arranged in a square, circular or other shaped structure. Specifically here, the air outlet frame 110 is arranged in a rectangular shape. The flow blocking layer 120 is installed inside the air outlet frame 110 (as Figure 4 shown), and the multiple flow blocking rods 121 of the flow blocking layer 120 are all strip-shaped and extend along the length direction of the air outlet frame 110; and the multiple flow blocking rods 121 are arranged at intervals in the width direction of the air outlet frame 110, so that an air outlet gap 101 is formed at intervals between two adjacent flow blocking rods 121, and the air outlet gap 101 is suitable for allowing air flow to pass through.

[0055] When the air flow entering the air outlet frame 110 hits the flow blocking layer 120, the air flow hits the multiple flow blocking rods 121 of the flow blocking layer 120 and is blocked from flowing, resulting in the Karman vortex street effect. Furthermore, Karman vortex street vortices are formed around the flow blocking rods 121, and the Karman vortex street vortices around adjacent flow blocking rods 121 collide with each other, reducing the speed of the air flow, thereby achieving windless feeling air outlet.

[0056] It can be understood that since the multiple flow blocking rods 121 are all strip-shaped, the air outlet gap 101 formed between two adjacent flow blocking rods 121 is a long and narrow slit. Therefore, during the process of windless feeling air outlet, compared with the conventional air outlet micro-holes, the air outlet resistance of the air outlet gap 101 is smaller, and the air flow rate that can pass through the air outlet gap 101 is larger. Furthermore, it can ensure that the air outlet module 100 has a larger windless feeling air outlet volume, effectively improving the comfort of windless feeling air outlet.

[0057] In the technical solution of the present invention, by arranging the flow blocking layer 120 inside the air outlet frame 110 of the air outlet module 100, the flow blocking layer 120 includes multiple flow blocking rods 121 arranged at intervals in the width direction of the air outlet frame 110, and the flow blocking rods 121 are strip-shaped and extend along the length direction of the air outlet frame 110. Thus, the flow blocking rods 121 of the flow blocking layer 120 can block the air flow, so that Karman vortex street vortices are formed around the flow blocking rods 121, and the Karman vortex street vortices around adjacent flow blocking rods 121 collide with each other to reduce the speed of the air flow, thereby achieving windless feeling air outlet. After that, the windless feeling air flow with reduced wind speed blows out from the air outlet gap of the flow blocking layer 120. The air outlet resistance of the air outlet gap 101 is smaller, so a larger air flow rate can pass through, effectively increasing the windless feeling air outlet volume of the air outlet module 100 and improving the comfort of windless feeling air outlet.

[0058] Please refer to Figures 4 to 6, for the number of the flow blocking layers 120 of the air outlet module 100, it can be one, two or more than two. In this embodiment, the air outlet module 100 includes a plurality of flow blocking layers 120, and the plurality of flow blocking layers 120 are arranged at intervals along the air outlet direction of the air outlet frame 110. After the air outlet airflow sequentially passes through the plurality of flow blocking layers 120 along the air outlet direction of the air outlet frame 110, the speed of the air outlet airflow gradually decreases, and is impacted by the plurality of flow blocking layers 120 to form a relatively disordered turbulent flow, thereby realizing soft wind and windless feeling air outlet, and greatly improving the comfort of windless feeling air outlet.

[0059] Please refer to Figure 6 and Figure 7 , in one embodiment, among two adjacent flow blocking layers 120 of each air outlet module 100, the plurality of flow blocking rods 121 in one flow blocking layer 120 are arranged in a staggered manner in the interlayer arrangement direction with the plurality of flow blocking rods 121 in the other flow blocking layer 120. For the convenience of explanation, assume that the two adjacent flow blocking layers 120 are the first flow blocking layer 120a and the second flow blocking layer 120b respectively. Then, the flow blocking rods 121 of the first flow blocking layer 120a are opposite to the air outlet gaps 101 of the second flow blocking layer 120b. Correspondingly, the flow blocking rods 121 of the second flow blocking layer 120b are also opposite to the flow blocking rods 121 of the second flow blocking layer 120b.

[0060] During the process of the airflow passing through the air outlet module 100, the airflow is first blocked by the flow blocking rods 121 of the first flow blocking layer 120a to form the first von Kármán vortex street vortices, and the von Kármán vortex street vortices of two adjacent flow blocking rods 121 of the first flow blocking layer 120a collide with each other to form a turbulent flow; then the turbulent flow flows from the air outlet gap 101 of the first flow blocking layer 120a to the second flow blocking layer 120b, and correspondingly impacts on the flow blocking rods 121 of the second flow blocking layer 120b corresponding to the air outlet gap 101 of the first flow blocking layer 120a, thereby causing the airflow to be blocked again to form the second von Kármán vortex street vortices, and the von Kármán vortex street vortices of two adjacent flow blocking rods 121 of the second flow blocking layer 120b collide with each other, and the collision effect is more obvious, greatly improving the comfort of soft wind and windless feeling air outlet.

[0061] Please refer to Figure 6 and Figure 7 , further, the distance between two adjacent flow blocking layers 120 of each air outlet module 100 is adjustable. Among them, Figure 7In the figure, D indicates the distance between two adjacent flow blocking layers 120. For example, when driving the first flow blocking layer 120a closer to the second flow blocking layer 120b, the distance between these two flow blocking layers 120 is shortened, so that the flow blocking rods of the second flow blocking layer 120 are closer to the air outlet gap of the first flow blocking layer 120. As a result, the air flow blown out from the air outlet gap of the first flow blocking layer 120 directly and quickly impacts on the flow blocking rods of the second flow blocking layer 120, and the wind speed is quickly reduced, which can make the no-wind feeling effect better. On the contrary, increasing the distance between the two flow blocking layers 120 can weaken the no-wind feeling effect.

[0062] As for the ways to realize the adjustable distance between two adjacent flow blocking layers 120, there can be various design methods. For example, two adjacent flow blocking layers 120 can both move relatively, or one of the flow blocking layers 120 is fixed and the other flow blocking layer 120 can move relative to this flow blocking layer 120. The installation method for the flow blocking layer 120 to be movable can be: the flow blocking layer 120 is slidably matched with the air outlet frame 110 through a slide rail structure, or the flow blocking layer 120 is rollingly matched with the air outlet frame 110 through a roller structure. The driving method of the flow blocking layer 120 can be manual or electric. For example, a driving component is installed on the air outlet frame 110, and this driving component is connected to the flow blocking layer 120, and then the flow blocking layer 120 is driven to move through this driving component. The driving component can include a motor fixed on the air outlet frame 110, a gear connected to the motor, and a rack arranged on the flow blocking layer 120, and this rack meshes with the gear.

[0063] Please refer to Figure 7 , considering here that if the distance between two adjacent flow blocking layers 120 (such as Figure 18 where D represents the said distance) is too small, the air outlet gap will be relatively narrow, which will affect the air output; if the distance between two adjacent flow blocking layers 120 is too large, the volume of the air outlet module 100 will increase accordingly, which will occupy a relatively large space. Therefore, optionally, the distance between two adjacent flow blocking layers 120 is less than or equal to 2 mm and less than or equal to 15 mm. That is, 2 mm ≤ D ≤ 15 mm. Specifically, it can be but not limited to: 3 mm, 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, etc.

[0064] For each flow blocking layer 120 of the air outlet module 100, the cross-section of each flow blocking rod 121 of the flow blocking layer 120 can be circular (as shown in Figure 8 and Figure 7 ), rhombus (as shown in Figure 11 and Figure 12 ), oval (as shown in Figure 13 and Figure 14It can be set in any shape as shown). It should be noted that the cross-section of the flow blocking rod 121 is obtained by a plane perpendicular to its length direction. In this embodiment, the cross-section of the flow blocking rod 121 is set to be circular, so that the outer peripheral surface of the flow blocking rod is relatively smooth, which helps the air flow to form a von Kármán vortex street vortex after colliding with the flow blocking rod.

[0065] The diameter of each flow blocking rod 121 can remain unchanged along the length direction of the flow blocking rod 121, that is, the flow blocking rod 121 is a regular cylinder. Of course, the diameter of each flow blocking rod 121 can also be variable, that is, the flow blocking rod 121 is an irregular cylinder, so that the von Kármán vortex street vortices formed by the air flow passing through different positions of the flow blocking rod 121 are different, and then the air flow is more disordered, forming a more natural natural wind.

[0066] Please refer to Figures 8 to 10 , in one embodiment, the flow blocking rod 121 has a plurality of flow blocking segments 1211 connected in sequence along its length direction, and the diameters at both ends of each flow blocking segment 1211 are larger than the diameter at the middle of the flow blocking segment 1211. In this way, the flow blocking rod 121 can be in the shape of a bamboo pole, and each flow blocking segment 1211 of the flow blocking rod 121 has a position with a larger diameter and a position with a smaller diameter, so that the air flow passing through different positions of each flow blocking segment 1211 will also form different vortex street vortices, improving the air dispersion effect.

[0067] The way that the diameters at both ends of each flow blocking segment 1211 are larger than the diameter at the middle of the flow blocking segment 1211, that is to say, the diameter of each flow blocking segment 1211 gradually increases from the middle of the flow blocking segment 1211 to both ends of the flow blocking segment 1211. Specifically, it can be: the diameter of each flow blocking segment 1211 gradually increases step by step in a ladder shape from the middle of the flow blocking segment 1211 to both ends of the flow blocking segment 1211; or, the diameter of each flow blocking segment 1211 linearly increases from the middle of the flow blocking segment 1211 to both ends of the flow blocking segment 1211. In this embodiment, the latter embodiment is adopted to make the outer surface of each flow blocking segment 1211 transition relatively smoothly and reduce the wind resistance.

[0068] Please refer to Figure 9 and Figure 10 , considering that, since the diameter of each flow blocking segment 1211 linearly increases from the middle of the flow blocking segment 1211 to both ends of the flow blocking segment 1211, there is a minimum diameter D min at the middle of the flow blocking segment 1211 and a maximum diameter D max . Through experimental research, it is found that the difference between the minimum diameter D min and the maximum diameter D max of the flow blocking segment 1211 should not be too large, otherwise the von Kármán vortex street vortices formed at the middle and both ends of the flow blocking segment 1211 are not easy to contact and collide, and the air flow dispersion effect is not good.

[0069] Based on this, through experimental research and analysis, it is obtained that when the ratio of the minimum diameter D min to the maximum diameter D max of the flow blocking section 1211 is greater than or equal to 0.4, the vortex streets formed in the middle and at both ends of the flow blocking section 1211 are prone to interfere with and collide with each other, and the air flow dispersion effect is better. Therefore, in this embodiment, the ratio of the minimum diameter D min to the maximum diameter D max of the flow blocking section 1211 should be greater than or equal to 0.4, that is, D min / D max ≥0.4, which means D min ≥0.4D max .

[0070] Of course, the difference between the minimum diameter D min and the maximum diameter D max of the flow blocking section 1211 should not be too small, otherwise the vortex streets formed in the middle and at both ends of the flow blocking section 1211 are not very different, and the formed turbulent flow effect is not good. Therefore, the ratio of the minimum diameter D min to the maximum diameter D max of the flow blocking section 1211 is also less than or equal to 0.9, that is, D min / D max ≤0.9, which means D min ≤0.9D max . Thus, 0.4D max ≤D min ≤0.9D max . Specifically, it can be but is not limited to: D min =0.5D max , 0.6D max , 0.7D max , 0.8D max .

[0071] Furthermore, since the minimum diameter D min of the flow blocking section 1211 should not be too small, optionally here, the range of the minimum diameter Dmin of each flow blocking section 1211 is greater than or equal to 1 mm to 8 mm, such as 1 mm, 2 mm, 4 mm, 5 mm, 6 mm, 7 mm. Based on the foregoing 0.4D max ≤D min ≤0.9D max , therefore, the maximum diameter D min of the flow blocking section 1211 can be correspondingly selected according to the value of the minimum diameter D max of each flow blocking section 1211.

[0072] Please refer to Figure 9 andFigure 10 In one embodiment, the flow blocking rod 121 further has a flow blocking joint connecting any two adjacent flow blocking segments 1211. The diameter of the flow blocking joint is greater than or equal to the diameters of the two ends of the flow blocking segment 1211. This flow blocking joint has greater strength and can strongly connect two adjacent flow blocking segments 1211 together (similar to a bamboo pole), preventing the disconnection of two adjacent flow blocking segments 1211.

[0073] Based on any of the above embodiments, it is considered that since the flow blocking rod is relatively long and narrow, during transportation or disassembly and assembly, the flow blocking rod 121 may be broken and damaged, resulting in the failure of the function of the air outlet module 100.

[0074] To address this situation, in one embodiment, two adjacent flow blocking segments 1211 on the flow blocking rod 121 are detachably connected. Thus, during transportation, the flow blocking rod 121 can be disassembled into multiple flow blocking segments 1211 for packaging, and then assembled after being transported to the destination. Moreover, when an individual flow blocking segment 1211 of the flow blocking rod 121 breaks, the broken flow blocking segment 1211 can be disassembled, and then a spare flow blocking segment 1211 can be replaced and installed on the flow blocking rod 121, so that the entire air outlet module 100 does not need to be replaced.

[0075] Regarding the detachable connection method of two adjacent flow blocking segments 1211 on the flow blocking rod 121, there are various design methods. For example, but not limited to: mutually matching threads are provided on the two adjacent flow blocking segments 1211 and are connected by screwing; or, one of the two adjacent flow blocking segments 1211 is inserted onto the other for insertion connection; or, one of the two adjacent flow blocking segments 1211 is provided with a buckle, and the other is provided with a slot matching the buckle for buckle connection.

[0076] In another embodiment, to reduce the occurrence of breakage of the flow blocking rod 121 during transportation, two adjacent flow blocking segments 1211 on the flow blocking rod 121 can also be movably connected so that the length of the flow blocking rod 121 is adjustable. During transportation, the length of the flow blocking rod 121 can be movably shortened, making it easy to be stored, packaged, and placed, and not easily broken or damaged. Moreover, since the two adjacent flow blocking segments 1211 remain connected after the flow blocking rod 121 is shortened, they are not easily lost.

[0077] Regarding the movable connection method of two adjacent flow blocking segments 1211 on the flow blocking rod 121, there are various design methods. For example, but not limited to: one of the two adjacent flow blocking segments 1211 is telescopically installed on the other (such as the telescopic strut of an umbrella); or, the two adjacent flow blocking segments 1211 are movably connected by a universal joint, enabling the two adjacent flow blocking segments 1211 to be movably folded.

[0078] Please refer toFigure 15 , the present invention further provides an air conditioner 200, which includes a housing 210 and an air outlet module 100; wherein, the housing 210 is provided with an air outlet; the air outlet module 100 is installed on the housing 210, and the air outlet module 100 is adapted to block the air outlet. For the specific structure of the air outlet module 100, refer to the above embodiments. Since the air conditioner 200 adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one. It should be noted that the air conditioner 200 can be any one of a wall-mounted air conditioner indoor unit, a floor-standing air conditioner indoor unit, a mobile air conditioner 200, and a ceiling-mounted air conditioner 200. To avoid redundancy, the following embodiments will mainly take the wall-mounted air conditioner indoor unit as an example for explanation.

[0079] Please refer to Figures 15 to 17 , in one embodiment, the housing 210 of the air conditioner 200 is provided with an air inlet and an air outlet, and an air duct 211 is formed inside the housing 210, and the air duct 211 communicates the air inlet and the air outlet. The air conditioner 200 further includes a heat exchanger and a wind wheel 220, and both the heat exchanger and the wind wheel 220 are installed inside the housing 210.

[0080] In one embodiment, the number of the air outlet modules 100 can be one, or two or more. For example, the air conditioner 200 is provided with an air outlet module 100 at the front side of the air outlet to be adapted to block the front side of the air outlet; and / or, the air conditioner 200 is provided with an air outlet module 100 at the lower side of the air outlet to be adapted to block the lower side of the air outlet.

[0081] Please refer to Figure 17 and Figure 18 , for the installation manner of the air outlet module 100, there can be various design manners. Optionally herein, the air outlet module 100 is movably installed in the housing 210 along the up and down direction, so that the air outlet module 100 can be switched between a working position and an idle position. Wherein, in the working position, the air outlet module 100 is located in front of the air outlet; in the idle position, the air outlet module 100 is hidden inside the housing 210.

[0082] Specifically, a receiving cavity 212 for receiving and hiding the air outlet module is formed inside the front panel of the housing 210. When conventional air outlet is required, the air outlet module 100 is moved to the idle position, so that the air outlet module 100 is hidden in the receiving cavity 212, and thus the air outlet of the housing 210 is exposed, and the air outlet can normally send air forward; when the windless feeling is required, the air outlet module 100 is moved to the working position to block the front side of the air outlet, so that the air flowing forward forms a relatively gentle wind after changing into a turbulent flow through the air outlet module 100. Of course, the installation method of the air outlet module 100 is not limited to this. In other embodiments, the air outlet module 100 can also be rotatably installed on the upper part of the air outlet to switch between the working position and the idle position by rotation.

[0083] Please refer to Figures 18 to 20 , in an embodiment, to facilitate the installation of the air outlet module 100, the air conditioner 200 further includes an installation component 300, and the installation component 300 includes an installation seat 310 and an installation plate 320. Among them, the installation seat 310 is arranged inside the housing 210 and fixedly connected to the housing 210; the installation plate 320 is fixedly connected to the air outlet frame 110 of the air outlet module 100, and the air outlet frame 110 is movably installed on the installation seat 310 along the up and down direction through the installation plate 320.

[0084] Specifically, the installation seat 310 is installed on the inner surface of the front panel of the housing 210, and the installation seat 310 is provided with a static rail 311 extending along the up and down direction; the installation plate 320 is fixedly connected to the air outlet frame 110, and the installation plate 320 is provided with a moving rail 321 corresponding to the static rail 311, and the moving rail 321 is slidably matched with the static rail 311, so that the installation plate 320 moves relative to the installation seat along the up and down direction, and further drives the air outlet module 100 to move through the installation plate 320.

[0085] Please refer to Figures 18 to 21 , further, the air conditioner 200 further includes a driving component 240, and the driving component 240 includes a rack 241, a motor and a gear; among them, the rack 241 is installed on the air outlet module 100; the motor is installed inside the housing 210; the gear is connected to the motor and meshes with the rack 241.

[0086] In other embodiments, the driving component 240 may include a motor, a reel and a towing rope; among them, the reel is rotatably installed inside the housing 210, the towing rope is wound on the reel, and the other end of the towing rope is connected to the air outlet module 100; the motor is connected to the reel to drive the reel to wind the towing rope to drive the air outlet module 100 to move up and down.

[0087] Please refer to Figures 15 to 17, Based on any of the above embodiments, the air conditioner 200 further includes a wind deflector 230 disposed below the air outlet. The wind deflector 230 is rotatably connected to the housing 210 to open or close the air outlet by rotation. When the air outlet module 100 moves to the front side of the air outlet, the wind deflector 230 can be rotated to block the lower side of the air outlet, so as to cooperate with the air outlet module 100 to block the air outlet. At this time, the wind deflector 230 can guide a large amount of air flow to flow forward, and then pass through and blow out from the air outlet module 100, effectively increasing the air volume of the comfortable draft-free feeling and improving the comfort of the comfortable draft-free feeling.

[0088] The above are only the optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields are all included in the patent protection scope of the present invention.
