However, this dust prevention method has certain defects. When the air conditioner is not used for a long time, the dust in the air will adsorb on the surface of the dust filter net, affecting the subsequent ventilation effect of the air conditioner.

[0009] Preferably, the cleaning mechanism includes a brush fixedly connected to the inner wall of the sealing plate. A plurality of first air suction pipes penetrate through the side wall of the sealing plate. The other end of the first air suction pipe is connected to an air pressure box, and the air pressure box is fixedly connected to the outer wall of the air conditioner housing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0024] In one embodiment, please refer to Figure 1 and Figure 2 , an air outlet control device for an air conditioner, including an air conditioner housing 1, one side of the air conditioner housing 1 is provided with an air outlet 5, and symmetrically distributed sealing plates 6 are arranged inside the air outlet 5. Rotating rods 7 penetrate through the inside of the sealing plates 6, and the rotating rods 7 are fixedly connected to the sealing plates 6. The rotating rods 7 penetrate through the side wall of the air conditioner housing 1 and are rotatably connected to the side wall of the air conditioner housing 1. One end of the rotating rod 7 is connected with a rotating mechanism 2, and the rotating mechanism 2 is used to drive the two sealing plates 6 to rotate mirror-symmetrically. One end of the sealing plates 6 close to each other is connected with a filtering mechanism 3, and the filtering mechanism 3 is used to filter the air to prevent dust in the air from entering the inside of the air conditioner housing 1. Cleaning mechanisms 4 are arranged inside the sealing plates 6, and the cleaning mechanisms 4 are used to clean the dust on the surface of the filtering mechanism 3.

[0025] In this embodiment, when the air conditioner needs to blow air, the rotating mechanism 2 drives the sealing plates 6 to rotate mirror-symmetrically through the rotating rods 7, so that the air outlet 5 is in an open state, and then the air conditioner can blow air. During the air blowing process, the filtering mechanism 3 can filter the dust in the air, thereby preventing the dust in the air from entering the inside of the air conditioner housing 1. The rotation angle of the rotating rod 7 can be controlled according to the actual situation, which can adjust the distance between the ends of the sealing plates 6, so as to control the air outlet range. When the air conditioner does not need to blow air, the rotating mechanism 2 drives the sealing plates 6 to rotate in the opposite direction through the rotating rods 7 until the ends of the sealing plates 6 are closed. The air outlet 5 is sealed by the sealing plates 6, which can avoid the phenomenon that dust in the air adheres to the surface of the filtering mechanism 3 when the air conditioner is not used for a long time, thereby ensuring the subsequent filtering effect of the filtering mechanism 3 on dust. And during the closing process of the sealing plates 6, the cleaning mechanisms 4 inside the sealing plates 6 will automatically clean the dust on the surface of the cleaning mechanisms 4, which can further ensure the subsequent filtering effect of the filtering mechanism 3 on dust.

[0026] Please refer to Figure 1 , the rotating mechanism 2 includes motors symmetrically arranged on the side wall of the air conditioner housing 1. The output ends of the motors are respectively fixedly connected to the rotating rods 7 on the two sealing plates 6, and the rotation directions of the two motors are opposite; When the air conditioner needs to blow air, the motor drives the sealing plate 6 to rotate mirror-symmetrically through the rotating rod 7, so that the air outlet 5 is in an open state, thus achieving the purpose of ventilation. Moreover, the rotation angle of the output end of the motor can be controlled according to the actual situation, which can adjust the distance between the sealing plates 6, thereby controlling the air outlet range and having a wide application range. When the air conditioner finishes blowing air, the motor drives the sealing plate 6 to rotate in the reverse direction through the rotating rod 7, so that the ends of the two sealing plates 6 are closely attached, playing a sealing role for the air outlet 5, and effectively avoiding the phenomenon that dust in the air enters the interior of the air conditioner housing 1 when the air conditioner does not blow air.

[0027] Please refer to Figure 2 and Figure 4 , the filtering mechanism 3 includes a dust-proof net 31 arranged between the two sealing plates 6. The two ends of the dust-proof net 31 are respectively inserted into the interior of the sealing plate 6 from the ends of the sealing plate 6. The dust-proof net 31 is slidably connected to the sealing plate 6, and one end of the dust-proof net 31 inserted into the interior of the sealing plate 6 is connected to the inner wall of the sealing plate 6 through a buffer assembly, and the buffer assembly is used to provide a pulling force to the dust-proof net 31; When the air conditioner needs to blow air, the two sealing plates 6 are driven to rotate mirror-symmetrically through the rotating mechanism 2. During the mirror-symmetric rotation of the sealing plates 6, a relative displacement will occur between the dust-proof net 31 and the sealing plate 6, so that the dust-proof net 31 can move to the outside of the sealing plate 6. At this time, the dust can be filtered through the dust-proof net 31, thereby preventing the dust in the air from entering the interior of the air conditioner housing 1 through the air inlet. When the air conditioner finishes blowing air, the rotating mechanism 2 drives the sealing plate 6 to rotate in the reverse direction, so that the sealing plates 6 are closed to each other. During the closing process of the sealing plates 6, the dust-proof net 31 is automatically retracted into the two sealing plates 6 under the action of the buffer assembly. The buffer assembly includes a slider 33 fixedly connected to the end of the dust-proof net 31. The slider 33 is slidably connected to the inner wall of the sealing plate 6. The end of the slider 33 away from the dust-proof net 31 is connected to the inner wall of the sealing plate 6 through a first elastic member 32. The first elastic member 32 and the slider 33 provide a pulling force to the dust-proof net 31, so that the dust-proof net 31 can be automatically retracted into the sealing plate 6 when the two sealing plates 6 are closed. The first elastic member 32 can be a spring.

[0028] Please refer to Figure 2 and Figure 5 , the cleaning mechanism 4 includes a brush 41 fixedly connected to the inner wall of the sealing plate 6. A plurality of first air suction pipes 42 penetrate through the side wall of the sealing plate 6. The other end of the first air suction pipe 42 is connected to an air pressure box 43. The air pressure box 43 is fixedly connected to the outer wall of the air conditioner housing 1. The air pressure box 43 is connected with an air suction component. When the sealing plate 6 is closed, the air suction component is used to suck the gas inside the air pressure box 43; When the air conditioning stops blowing air, the motor drives the sealing plate 6 to rotate in the reverse direction through the rotating rod 7, so that the ends of the two sealing plates 6 are closely attached. During the closing process of the sealing plate 6, the dust-proof net 31 can be retracted into the sealing plate 6 under the action of the first elastic member 32. At this time, the brush 41 inside the sealing plate 6 will clean the dust-proof net 31 during its movement, so that dust no longer adheres to the surface of the dust-proof net 31, thereby playing a cleaning role on the dust on the surface of the dust-proof net 31. And during the closing process of the sealing plate 6, the suction assembly sucks the gas inside the air pressure box 43, the air pressure inside the air pressure box 43 decreases, and then the first suction pipe 42 sucks the gas inside the sealing plate 6 into the air pressure box 43. During the suction process of the first suction pipe 42, the dust cleaned by the brush 41 will enter the air pressure box 43 along with the air flow, thus preventing the dust from adhering to the surface of the dust-proof net 31 again, effectively improving the cleaning effect on the dust-proof net 31, and there is no need for manual cleaning of the dust-proof net 31, saving manpower. In addition, an adsorption layer can be arranged inside the air pressure box 43 to adsorb the dust, so as to prevent the dust from flowing back into the sealing plate 6 through the first suction pipe 42. The adsorption layer can be an activated carbon adsorption layer. In order to avoid the interference of the first suction pipe 42 on the rotation of the sealing plate 6, the first suction pipe 42 can be a flexible pipe.

[0029] Please refer to Figure 1 and Figure 3 As shown in the figure, the suction assembly includes a mounting plate 45 fixedly connected to the outer wall of the air conditioner housing 1. A pressure cylinder 46 penetrates through the mounting plate 45. The pressure cylinder 46 is communicated with a second suction pipe 44, and the other end of the second suction pipe 44 is communicated with the air pressure box 43. A piston 47 is slidably connected inside the pressure cylinder 46. The piston 47 is fixedly connected to a support rod 48. The support rod 48 penetrates through the end of the pressure cylinder 46 and is slidably connected thereto. A baffle 410 is fixed to the end of the support rod 48 away from the piston 47. An extrusion member is provided outside the rotating rod 7, and the extrusion member is used to extrude the baffle 410; When the air conditioning stops blowing air, the rotating mechanism 2 drives the sealing plate 6 to rotate in the reverse direction through the rotating rod 7. During the reverse rotation process of the sealing plate 6, the extrusion member extrudes the baffle 410, and the baffle 410 drives the piston 47 to move inside the pressure cylinder 46 through the support rod 48, and a negative pressure is formed inside the pressure cylinder 46, and then the gas inside the air pressure box 43 is sucked through the second suction pipe 44.

[0030] Please refer to Figure 1 As shown in the figure, the extrusion member includes a push plate 411 fixed to the end of the rotating rod 7 and capable of extruding the baffle 410. A second elastic member 49 is provided outside the support rod 48, and both ends of the second elastic member 49 are fixedly connected to the baffle 410 and the end of the pressure cylinder 46 respectively; When the air conditioner finishes blowing air, while the motor drives the sealing plate 6 to rotate in the reverse direction through the rotating rod 7, it also drives the push plate 411 to rotate through the rotating rod 7. During the rotation of the push plate 411, it will squeeze the baffle 410, so that the baffle 410 drives the piston 47 to move inside the air pressure cylinder 46 through the support rod 48. When the air conditioner needs to blow air again, the motor drives the rotating rod 7 to rotate in the forward direction, the push plate 411 no longer squeezes the baffle 410, and the baffle 410 drives the piston 47 to automatically reset through the support rod 48 under the action of the second elastic member 49, where the second elastic member 49 can be a spring.

[0031] Please refer to Figures 1-6 , an air outlet control method for an air conditioner, which uses the air outlet control device as described above, and includes the following steps: S1. When the air conditioner blows air, the rotating rod 7 drives the sealing plate 6 to rotate, the sealing plates 6 move away from each other, and the dust-proof net 31 moves to the outside of the sealing plate 6; S2. When the air conditioner does not blow air, the rotating rod 7 drives the sealing plate 6 to rotate, the sealing plates 6 move closer to each other, and the dust-proof net 31 automatically moves to the inside of the sealing plate 6; S3. During the process of the dust-proof net 31 moving to the inside of the sealing plate 6, the dust on the surface of the dust-proof net 31 is cleaned by the brush 41 inside the sealing plate 6; S4. The dust cleaned is sucked into the air pressure box 43 through the first suction pipe 42.

[0032] Working principle: When the air conditioner needs to blow air, the rotation mechanism 2 drives the two sealing plates 6 to rotate mirror-symmetrically. During the mirror-symmetric rotation of the sealing plates 6, a relative displacement occurs between the dust-proof net 31 and the sealing plates 6, so that the dust-proof net 31 can move to the outside of the sealing plates 6. At this time, the dust can be filtered through the dust-proof net 31, thereby preventing the dust in the air from entering the interior of the air conditioner housing 1 through the air inlet. When the air conditioner finishes blowing air, the rotation mechanism 2 drives the sealing plates 6 to rotate in the reverse direction, so that the sealing plates 6 are closed to each other. During the closing process of the sealing plates 6, the dust-proof net 31 is automatically retracted into the two sealing plates 6 under the action of the buffer assembly. At this time, the brush 41 inside the sealing plate 6 will clean the dust-proof net 31 during the movement, so that the dust no longer adheres to the surface of the dust-proof net 31, thus playing a cleaning role on the dust on the surface of the dust-proof net 31. And during the reverse rotation of the sealing plate 6, the rotating rod 7 squeezes the baffle 410 through the push plate 411, so that the baffle 410 drives the piston 47 to move inside the air pressure cylinder 46 through the support rod 48. A negative pressure is formed inside the air pressure cylinder 46, and then the gas inside the air pressure box 43 is sucked through the second suction pipe 44. The air pressure inside the air pressure box 43 decreases, so that the first suction pipe 42 sucks the gas inside the sealing plate 6 into the air pressure box 43. During the suction process of the first suction pipe 42, the dust cleaned by the brush 41 will enter the air pressure box 43 along with the air flow, thus preventing the dust from adhering to the surface of the dust-proof net 31 again, effectively improving the cleaning effect on the dust-proof net 31, and there is no need for manual cleaning of the dust-proof net 31, saving manpower.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
