The present application includes the following beneficial effects:
The technical solution of the present application adopts the middle frame and the front panel. The middle frame is provided with a plurality of installation holes, and the installation holes include the through hole section and the fastening section communicated with the through hole section. For each installation hole, the front panel is provided with a fastening member. The fastening member passes through the through hole section and moves to the fastening section to fasten with the fastening section, so that the front panel is installed on the middle frame. It can be seen that this assembly method is not only simple in structure, but also simple in connection procedure. The fastening member is only put into the installation hole, and the fastening member is moved from the through hole section to the fastening section to complete the installation of the front panel. Not only does it have fewer assembly parts and extremely high assembly efficiency, it also greatly reduces the use of screws. It is beneficial to save the installation process, thereby saving the production cost.
The technical solution of the present application adopts the top panel and the middle frame, and the opposite ends of the top panel are provided with connection side members extending downward; the middle frame includes two opposite side panels, and the upper end of each side panel is correspondingly connected to one connection side member; a buckle structure and a screw lock structure are provided between the upper end of the side panel and the connection side member. Because the buckle structure has connected the top panel and the side panel to each other, the screw lock structure can solve the gap problem between the top panel and the middle frame with the depth of the screw connection. It can be understood that the tighter the screw is, the smaller the gap between the top panel and the middle frame is, and the combination of the buckle structure and the screw lock structure can make the gap between the top panel and the middle frame control within 0.5 mm to 0.8 mm. The smaller the gap is, the more difficult it is for impurities such as dust in the external environment to enter the casing. Because impurities entering the housing assembly will corrode the devices in the housing assembly, thereby affecting the service life of the mobile air conditioner. Not only that, the assembly method of the buckle structure and the screw lock structure is simple in structure, and the connection is stable, so that the housing assembly is stronger.
In the technical solution of the present application, the drive motor is connected to an air deflector through a non-conductive shaft, and the connection rod is connected to each air deflector. In this way, the drive motor can drive an air deflector to rotate to drive the movement of the connection rod, and the connection rod drives all of the air deflectors to rotate synchronously. In addition, if any two adjacent air deflectors are parallel to each other, the wind flowing out from the air outlet will be in the same direction under the action of the air deflectors, so that the user has a better experience. It is worth mentioning that the surface of the drive motor is easy to carry current, and the drive motor is connected to the air deflector through the non-conductive shaft, which can prevent the current of the drive motor from being transmitted to the air deflector, thereby avoiding damage to other components in the air conditioner, and avoiding that a large amount of dust is absorbed on the surface of the air deflector.

The present application proposes a housing assembly 100.
Referring to
In an embodiment, the cross-sectional area of the through hole section 211 is larger than that of the fastening section 213, which is to facilitate the fastening member 310 to enter the installation hole 210 and improve the convenience of installation. The installation process of the front panel 300 and the middle frame 200 is as follows: the fastening member 310 is just put into the installation hole 210, and the fastening member 310 is moved from the through hole section 211 to the fastening section 213 to complete the installation of the front panel 300. It is not difficult to understand that when it needs to be disassembled, it is only necessary to move the front panel 300 towards the direction of the through hole section 211, and the front panel 300 can be removed from the installation hole 210 by pulling the action. At this time, the disassembly path of the fastening member 310 is: it gradually moves from the fastening section 213 to the through hole section 211, and finally escape from the through hole section 211. The technical solution of the present application has fewer assembly parts and simple installation process, which greatly improves the assembly efficiency of the front panel 300 and the middle frame 200, and the technical solution also greatly reduces the use of screws, so it is beneficial to save the installation process and thus save production cost.
Furthermore, multiple front panels 300 may be provided, and the styles of the multiple front panels 300 may be the same or different. For example but not limited thereto, when the front panel 300 is scratched or cracked, only the front panel 300 needs to be replaced, and the housing assembly 100 will look brand new. The assembly method of the housing assembly 100 is simple, and the user can replace it by himself without requiring professionals, which greatly improves the convenience of use. Of course, the present application is not limited thereto, and in some other embodiments, only one front panel 300 may be provided.
Furthermore, the fastening member 310 and the front panel 300 are integrally formed. The integrally formed structure has high rigidity, good integrity, stronger stability and is not easy to break. The integrally formed structure also makes the manufacturing process and installation process more convenient and quicker. Of course, the present application is not limited thereto, and in some other embodiments, the fastening member 310 and the front panel 300 may also be fixed together by welding.
In an embodiment, the fastening section 213 is located on the lower side of the through hole section 211, so that the connection between the front panel 300 and the middle frame 200 can be made more stable by the action of gravity, so that the fastening member 310 is tightly fastened to the fastening section 213. During installation, it is only necessary to put the fastening member 310 into the through hole section 211, and the front panel 300 will pass through the transition section 212 from the through hole section 211 and then enter the fastening section 213 under the guidance of the transition section 212 and the action of gravity. Finally the fastening member 310 will be stuck on the lower edge of the fastening section 213, which also makes the installation more labor-saving. The fastening section 213 can also be located on the upper side of the through hole section 211.
In an embodiment, the installation hole 210 further includes a transition section 212 located between the through hole section 211 and the fastening section 213, and the transition section 212 is gradually reduced in a direction close to the fastening section 213. It can be understood that the width of the transition section 212 decreases gradually in a direction approaching the fastening section 213. This helps to guide the fastening member 310 into the fastening section 213, avoiding the fastening member 310 from being stuck in the transitional step between the through hole section 211 and the fastening section 213, which can improve the efficiency of installation, and also make the installation of the front panel 300 and the middle frame 200 more labor-saving.
Further, one side of the transition section 212 is a beveled side, and the other side is a straight side, which can reduce processing techniques, improve work efficiency, and further reduce production costs. Of course, the present application is not limited thereto. In some other embodiments, both sides of the transition section 212 are hypotenuses.
In an embodiment, a side of the fastening member 312 is provided with a limitation convex 312a, and the limitation convex 312a and the fastening member 312 are fastened to different edges of the fastening section 213 respectively. The setting of the limitation convex 312a can prevent the fastening member 312 from moving back and forth, so that the connection between the front panel 300 and the middle frame 200 is more stable. It can be understood that the front and rear movement of the fastening member 312 will inevitably cause the front panel 300 to move forward and backward, and the setting of the limitation convex 312a can ensure the stability of the connection between the front panel 300 and the middle frame 200. Of course, the present application is not limited thereto. In the second embodiment, a limitation slot may also be provided at the fastening member 312, and a limitation protrusion may be provided in the installation hole 210.
Referring to
Furthermore, the connection arm 311 and the fastening member 312 are integrally formed, and the integrally formed structure has strong stability and is not easy to break. Therefore, adopting an integrally formed structure is conducive to improving the structural strength of the fastening member 310, thereby improving the connection between the middle frame 200 and the front panel 300, and further increasing the practical life of the housing assembly 100.
In an embodiment, the fastening member 312 is arranged at the lower side of the connection arm 311. It can be understood that the fastening member 310 is like a hook at this time, and when the front panel 300 and the middle frame 200 are installed, the fastening member 310 will be tightly hung on the lower end of the fastening section 213. Protruding downward from the connection arm 311, the fastening member 312 is also beneficial to utilize gravity to make the connection structure more stable. Of course, the present application is not limited thereto, and in some other embodiments, the fastening member 312 may also protrude from the connection arm 311 toward the side.
Referring to
In an embodiment, the edge of the fastening surface is provided with a limitation protrusion 312b, and the edge of the fastening section 213 is provided with a limitation recess, and when installed, the limitation protrusion 312b will fit into the limitation recess. In another embodiment, the edge of the fastening section 213 is provided with a limitation protrusion 312b, and the edge of the fastening surface is provided with a limitation recess.
Further, the limitation protrusion 312b is provided at the side of the fastening member 312 facing the connection arm 311, so that the limitation protrusion 312b can prevent the fastening member 310 from rebounding, and can also achieve a certain position-limiting effect. When it is disassembled, it does not affect the disassembly. However, the present application is not limited thereto. In the second embodiment, the limitation protrusion 312b is arranged at a side of the fastening member 312 away from the connection arm 311.
In an embodiment, a reinforcement rib 311a is provided at the connection between the connection arm 311 and the front panel 300. This can help to increase the strength of the fastening member 310, avoiding the breakage of the connection arm 311 without affecting the fastening strength of the fastening member 310.
Further, in the direction close to the fastening member 312, the cross-sectional area of the reinforcement rib 311a is gradually reduced, which is conducive to guiding the fastening member 310 to slide into the fastening section 213, and improves installation efficiency and makes installation more labor-saving. Of course, the present application is not limited thereto. In the second embodiment, the cross-sectional area of the reinforcement rib 311a from the direction approaching the fastening member 312 may also be unchanged.
Further, the reinforcement rib 311a includes a first reinforcement rib 311a arranged under the fastening member 312. The first reinforcement rib 311a not only serves as a guide, but also serves as a position limiter, limiting the fastening position and increasing the compactness of the structure.
Further, the top end of the connection arm 311 connected to the fastening member 312 is provided with a guide slope, which is beneficial to reduce the sharpness of the fastening member 310 and avoid scratching the operator. Of course, the present application is not limited thereto. In some other embodiments, the top end of the connection arm 311 connected to the fastening member 312 may also be provided with rounded corners.
Further, the free end of the fastening member 312 is provided with a straight chamfer, and/or the inner surface of the fastening member 312 is provided with a straight chamfer, so that the fastening member 310 can slide into the fastening section 213 more easily. However, the present application is not limited thereto. In some other embodiments, the free end of the fastening member 312 may also be rounded, and/or the inner surface of the fastening member 312 may also be rounded.
Referring to
In an embodiment, the front side of the middle frame 200 includes an upper side, a lower side, a left side and a right side, and installation holes 210 are provided at the upper side, the lower side, the left side and the right side. It can be understood that the connection surface of the front panel 300 includes an upper side, a lower side, a left side and a right side, and the upper side, the lower side, the left side and the right side are all provided with a fastening member 310. This helps to increase the compactness of the connection, avoid warping caused by uneven placement of the installation holes 210, and further reduce the gap between the front panel 300 and the middle frame 200.
Further, the fastening members 310 are symmetrically distributed on the vertical center line of the front panel 300, which is beneficial to improve the stability of the installation. Of course, the present application is not limited thereto, and in some other embodiments, the fastening members 310 may also be symmetrically distributed on the horizontal centerline of the front panel 300.
Referring to
In an embodiment, when assembling, the top panel 110 and the middle frame 200 are first fastened, then the top panel 110 and the middle frame 200 are tightened with screws; because the buckle structure has connected the top panel 110 and the side panel 121 to each other, the screw lock structure 400 can solve the gap problem between the top panel 110 and the middle frame 200 by the depth of the screw connection. It can be understood that the tighter the screw is, the smaller the gap between the top panel 110 and the middle frame 200 is. The combination of the buckle structure and the screw lock structure 400 can make the gap between the top panel 110 and the middle frame 200 controllable within 0.5-0.8 mm. The smaller the gap, the more difficult it is for impurities such as dust in the external environment to enter the housing; because impurities entering the housing assembly 100 will corrode the devices in the housing assembly 100, thereby affecting the service life of the mobile air conditioner. Furthermore, the assembly method of the buckle structure and the screw lock structure 400 is simple in structure and stable in connection, thereby making the housing assembly 100 more firm.

In an embodiment, the buckle 200a includes an elastic arm 210a extending downward, and a buckle member 220 arranged at the elastic arm 210a, and a lower surface of the buckle member 220 is configured as a guide slope 221.
In an embodiment, the setting of the elastic arm 210a greatly increases the convenience of installation, making it easier for the buckle member 220 to snap into the buckle hole 230. It can be understood that as long as the operator presses the buckle member 220 lightly, the elastic arm 210a will shrink, and then enter the buckle hole 230. When the operator releases his hand, the buckle member 220 will tightly buckle the side wall of the buckle hole 230 under the action of the elastic restoring force of the elastic arm 210a. Of course, the present application is not limited thereto, and in other embodiments, the buckle member 220 may also be arranged at the fixing plate.
Further, the purpose of setting the lower surface of the buckle member 220 as the guide slope 221 is to guide the buckle member 220 to snap into the buckle hole 230. In an embodiment, when the operator presses the buckle member 220, the buckle member 220 will follow the guide slope 221 to snap into the buckle hole 230, so that the connection structure is more convenient and labor-saving. Of course, the present application is not limited thereto, and in some other embodiments, the lower surface of the buckle member 220 may also be set to be perpendicular to the vertical surface of the elastic arm 210a.
Further, the free end surface of the elastic arm 210a close to the buckle member 220 is provided with a straight chamfer, which is also conducive to guiding the elastic arm 210a to slide into the buckle hole 230. Of course, the present application is not limited thereto, and in some other embodiments, the end surface of the elastic arm 210a near the buckle member 220 may also be provided with rounded corners.
Further, there is a certain distance between the buckle member 220 and the free end of the elastic arm 210a, so that there is a certain buffer zone when the buckle member 220 snaps into the buckle hole 230, so as to prevent the elastic arm 210a from popping out of the buckle hole 230 due to insufficient pressing. Of course, the present application is not limited thereto, and in some other embodiments, the buckle member 220 may also be directly arranged at the free end edge of the elastic arm 210a.
Further, the angle between the surface of the buckle member 220 away from the guide slope 221 and the elastic arm 210a is less than or equal to 90°. The purpose of such arrangement is to make the position of the buckle 200a of the buckle member 220 and the buckle hole 230 more stable. When the angle between the surface of the buckle member 220 away from the guide slope 221 and the elastic arm 210a is less than 90°, the buckle member 220 is like a hook, so that the surface of the buckle member 220 away from the guide slope 221 is tightly hooked to the side wall of the buckle hole 230; when the angle between the surface of the buckle member 220 away from the guide slope 221 and the elastic arm 210a is equal to 90°, the surface of the buckle member 220 away from the guide slope 221 will be tightly attached to the side wall of the buckle hole 230 to form a tight structure; however, the present design is not limited thereto. In the second embodiment, the angle between the surface of the buckle member 220 away from the guide slope 221 and the elastic arm 210a may also be greater than 90°.
In an embodiment, the upper end of the side panel 121 is provided with an inset installation step 122. The installation step 122 includes a first step surface 122a extending laterally and a second step surface extending up and down; the connection side member 111 is arranged at the installation step 122, and the buckle hole 230 is arranged at the first step surface 122a. The setting of the installation step 122 is to increase the connection surface between the top panel 110 and the middle frame 200 and increase the stability of the connection, and the installation step 122 can also give the top panel 110 sufficient supporting force, so that the structure of the top panel 110 and the middle frame 200 more stable. Of course, the present application is not limited thereto. In some other embodiments, the upper end of the side panel 121 may also be provided with a horizontal installation surface perpendicular to the middle frame 200.
Furthermore, the buckle hole 230 is provided at the first step surface 122a, which is beneficial to increase the stability of the buckle structure. Because the first step surface 122a is close to the middle frame 200, the strength of the first step surface 122a is greatly enhanced, thus the buckle hole 230 is arranged at the first step surface 122a to help the increasing strength of the buckle hole 230. Of course, the present application is not limited thereto, and in the second embodiment, the buckle hole 230 may also be arranged at the second step surface.
In an embodiment, the outer edge of the first step surface 122a is provided with a positioning rib (not shown), the lower end of the connection side member 111 is provided with a positioning slot 310a. The positioning rib is inserted into the positioning slot 310a, which facilitates to avoid relative displacement between the middle frame 200 and the top panel 110.

In an embodiment, when installing the screw lock structure 400, the screws should be installed from the inside of the housing assembly 100 outward, which helps to improve the aesthetics and hide the threaded holes 410 to enhance the aesthetics, and prevent the screws from being exposed to the environment. Because the screws are exposed to the environment, the corrosion is prone to occur, which reduces the service life of the housing assembly 100. Of course, the present application is not limited thereto, and in some other embodiments, the screws can also be installed from the outer side to the inner side of the housing assembly 100 during screw locking installation.
In an embodiment, the connection side member 111 has a first side and a second side oppositely arranged in the width direction, and at least one threaded hole 410 is opened on the buckle 200a close to the first side. This can make the connection position more compact. Because the gap between the top panel 110 and the middle frame 200 is mainly caused by the insufficient connection of the buckle structure, and setting the threaded hole 410 on the buckle 200a helps to increase the tightness of the buckle structure, thereby reducing the connection gap between the top panel 110 and the middle frame 200, so as to prevent sundries from entering the housing assembly 100. Of course, the present application is not limited thereto. In some other embodiments, the threaded hole 410 can also be provided with the buckle 200a at intervals.
Further, the threaded hole 410 is integrally formed with the buckle 200a. The one-piece molding structure has high rigidity, good integrity, stronger stability and is not easy to break, which can prevent the threaded hole 410 and buckle 200a from breaking when the screw is tightened, and the one-piece molding manufacturing process and installation process are more convenient and faster, which can improve production or installation efficiency. Of course, the present application is not limited thereto, and in some other embodiments, the threaded hole 410 and the buckle 200a may also be welded together.
In an embodiment, the positioning buckle 300a close to the second side is integrally connected with an installation protrusion, and at least one threaded hole 410 is opened on the installation protrusion. The buckle structure and the screw lock structure 400 are arranged at the opposite sides, which can avoid uneven stress on the opposite first side and the second side during connection, which may cause edge warping.

Since the mobile air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
In addition to the temperature level of the air conditioner that can affect people's experience, the flow direction of the air blown by the air conditioner is also one of the factors that affect people's experience. The air deflector is one of the key components that control the flow of the airflow blown by the air conditioner. The air deflector is plate-shaped, and its main function is to guide the airflow. If the angle of the air deflector changes, the airflow flowing out of the air deflector will also change accordingly to achieve the purpose of changing the direction of the airflow. However, at present, it is difficult for multiple air deflectors to rotate synchronously. As a result, the multiple airflows flowing out from the multiple air deflectors are inconsistent and the user experience is poor. Therefore, the present application proposes an air guide structure.

In the technical solution of the present application, the drive motor 7000 is connected to an air deflector 3000 through the non-conductive shaft 6000, and the connection rod 4000 is connected to each air deflector 3000. In this way, the drive motor 7000 can drive an air deflector 3000 to rotate to drive the connection rod 4000. The movement of the connection rod 4000 drives all the air deflectors 3000 to rotate synchronously. In addition, any two adjacent air deflectors 3000 are parallel to each other; under the action of the air deflectors 3000, the wind flowing out from the air outlet 230 has the same flow direction of each airflow, so that the user has a better experience. It is worth mentioning that the surface of the drive motor 7000 is prone to carry current. The drive motor 7000 is connected to the air deflector 3000 through the non-conductive shaft 6000, which can prevent the current of the drive motor 7000 from being conducted to the air deflector 3000, thereby avoiding damage to other components in the air conditioner, and preventing the surface of the air deflector 3000 from absorbing a large amount of dust.

In an embodiment, the air guide structure 1000 further includes a plurality of cranks 5000 arranged in parallel. One crank 5000 is set corresponding to one air deflector 3000, and the crank 5000 is arranged along the radial direction of the rotation shaft 3100. One end of the crank 5000 is rotatably connected to the connection rod 4000, and the other end is rotatably connected to the air deflector 3000. It can be understood that each crank 5000 is connected to the connection rod 4000. Under the action of the connection rod 4000, all cranks 5000 move synchronously to drive all the air deflectors 3000 move synchronously, so that users have a better experience. However, the present design is not limited thereto. In other embodiments, the air deflector is connected to the connection rod in rotation, and the rotational connection between the air deflector and the connection rod is outside the rotation shaft of the air deflector, that is, there is a certain distance between the rotation joint of the air deflector and the connection rod and the rotation shaft of the air deflector.
In an embodiment, the crank 5000 is detachably connected to the rotation shaft 3100. When the crank 5000 is damaged, a new crank 5000 can be replaced. It can be understood that the cost of replacing the crank 5000 alone is much less than replacing the crank 5000 and the air deflector 3000 as a whole. Or when the air deflector 3000 is damaged, a new air deflector 3000 can be replaced without the crank 5000 and the air deflector 3000 being replaced integrally, which saves costs. However, the design is not limited thereto. In other embodiments, if the connection strength between the crank and the air deflector is considered, the crank and the air deflector are integrally formed.

In an embodiment, the other end of the crank 5000 is provided with a clamping post 5300, and the connection rod 4000 is provided with a clamping hole for clamping the clamping post 5300. The clamping post 5300 has a first clamping section 5310, and a second clamping section 5320 coaxially connected to the first clamping section 5310. The second clamping section 5320 is arranged close to the clamping hole, and the second clamping section 5320 is in the shape of a circular cone. The radius of the lower bottom surface of the second clamping section 5320 is greater than the radius of the first clamping section 5310, and the first clamping section 5310 is connected to the lower bottom surface of the second clamping section 5320. The clamping post 5300 is provided with a gap extending along the axial direction of the clamping post 5300 to limit two sub clamping posts 5330. In this way, by squeezing the two sub clamping posts 5330 to make them close to each other, even if the gap becomes smaller, so that the second clamping section of the clamping post 5300 can pass through the clamping hole. Then the force applied on the two sub clamping posts 5330 is removed to reset the two sub clamping posts 5330. After the two sub clamping posts 5330 are restored, the clamping hole is located at the first clamping section 5310. It is worth mentioning that since the first clamping section 5310 is in the shape of a circular cone, after the upper bottom surface of the first clamping section 5310 passes through the clamping hole, the first clamping section 5310 continues to extend into the clamping hole. The outer peripheral surface of the first clamping section 5310 is abutted against the peripheral edge of the clamping hole. Under the squeeze of the peripheral edge of the clamping hole, the two sub clamping posts 5330 are close to each other, that is, the gap becomes smaller, so that the second clamping section 5320 of the clamping post 5300 can pass through the clamping hole. After the second clamping section 5320 passes through the clamping hole, the two sub clamping posts 5330 are reset. After the two sub clamping posts 5330 are restored, the clamping holes are located in the first clamping section 5310. In this way, the connection rod 4000 and the crank 5000 are firmly assembled.
In an embodiment, a first installation post 5400 protrudes from the side of the crank 5000 close to the air deflector 3000, and the limitation hole 5100 is provided at the first installation post 5400. It can be understood that after the rotation shaft 3100 of the air deflector 3000 is extended into the limitation hole 5100 by the first installation post 5400, the air deflector 3000 and the crank 5000 are installed more reliably.

In an embodiment, the air outlet frame 2000 is provided with a first shaft hole 2220 through which the rotation shaft 3100 can rotate, and the hole wall of the first shaft hole 2220 is provided with a limitation notch 2230 communicating with the first shaft hole 2220. The two stop positions 2240 are respectively the two opposite side walls of the limitation notch 2230. The crank 5000 is formed with a limitation rib 5200 extending into the limitation notch 2230, and the limitation rib 5200 can go back and forth between the two stop positions 2240. On the one hand, the limitation notch 2230 is easy to process, and only needs to open a gap on the hole wall of the first shaft hole 2220 to communicate with the first shaft hole 2220. On the one hand, in addition to the limiting function, the limitation member is also conducive to improving the structural strength of the crank 5000. In an embodiment, the limitation rib 5200 is connected to the first installation post 5400 to improve the structural strength of the first installation post 5400.
However, the present design is not limited thereto. In other embodiments, two stop posts protrude from the outer peripheral surface of the first shaft hole, and the two stop posts extend along the radial direction of the first shaft hole. The two stop positions are respectively two opposite sides of the two stop posts, and the limitation rib on the crank can go back and forth between the two stop posts.
In an embodiment, the air outlet frame 2000 is provided with a second installation post 2210, and the first shaft hole 2220 and the limitation notch 2230 are both provided at the second installation post 2210. It can be understood that after the second installation post 2210 makes the rotation shaft 3100 of the air deflector 3000 extend into the first shaft hole 2220, the installation of the air deflector 3000 and the air outlet 2300 is more reliable.
In an embodiment, referring to
In an embodiment, the air deflector 3000 is provided with a third installation post 3200 extending along the extension direction of the rotation shaft 3100, and the second shaft hole 3210 is provided in the third installation post 3200. It can be understood that after the non-conductive shaft 6000 is extended into the second shaft hole 3210 by the third installation post 3200, the non-conductive shaft 6000 and the air deflector 3000 are more reliably installed.
In an embodiment, the drive motor 7000 is a stepping motor, which is a motor that converts electrical pulse signals into corresponding angular displacements. Every time a pulse signal is input, the rotor rotates an angle, and the output angular displacement or linear displacement is proportional to the input pulse number, and the speed is proportional to the pulse frequency. Under the action of the stepping motor, the rotation angle of the air deflector 3000 can be control, and the rotation angle of the air deflector 3000 is determined, which is beneficial to adjust the angle of the air deflector 3000 to an appropriate value, so as to provide users with a better experience. However, this design is not limited to this, in other embodiments, if the cost is not considered, the drive motor can be a servo motor.
In an embodiment, there are multiple non-conductive shafts 6000, multiple drive motors 7000. One non-conductive shaft 6000 corresponds to one air deflector 3000, and one drive motor 7000 corresponds to one non-conductive shaft 6000. That is, each air deflector 3000 is correspondingly equipped with a non-conductive shaft 6000 and a drive motor 7000, and each air deflector 3000 rotates smoothly at the air outlet frame 2000 under the action of the corresponding drive motor 7000, which is beneficial to reduce the noise generated when the air deflector 3000 and the air outlet 2300 rotate relative to each other, thereby improving user experience. In addition, under the action of the connection rod 4000, even if a drive motor 7000 fails, each air deflector 3000 can also rotate synchronously.
The present application also proposes an air conditioner. Referring to
