Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and specifically relates to a ventilation and dust-proof device for an outdoor unit of an air conditioner. Background Art

[0002] During the operation of the outdoor unit of an air conditioner, good ventilation and heat dissipation are required. However, when it is exposed to the outdoor environment for a long time, it is easily blocked by foreign objects such as dust, leaves, catkins, and insects, which affects the heat dissipation efficiency, increases energy consumption, degrades performance, and even damages the equipment. Existing dust-proof technologies have some limitations and need to be improved and optimized. During the use of the outdoor unit of an air conditioner, generally after the air conditioner stops cooling or heating, the fan inside the outdoor unit of the air conditioner is reversed by a motor, and the generated airflow after reversal is blown towards the filter screen at the air inlet, thereby achieving the purpose of preventing dust from adhering to the filter screen. Since the motor inside the air conditioner sucks external gas through the air inlet during forward rotation and makes it flow into the air conditioner, when the external gas flows into the air conditioner during the forward rotation of the motor, the flowing gas will carry a large amount of dust and adhere to the filter screen. Due to the long-term adhesion and accumulation of dust on the filter screen, it is difficult for the airflow generated during the reverse rotation of the motor to clean the dust that has adhered for a long time and accumulated, affecting the use and the cleaning rate during reverse rotation. Summary of the Invention

[0010] Further, the lifting assembly includes a fixing block fixedly connected to one side wall of the sliding block.

[0011] Further, the pushing assembly includes a connecting rod II rotatably connected to the bottom of the sliding rod.

[0014] Furthermore, the auxiliary component includes a second arc-shaped plate fixedly connected to the inner wall of the main body.

[0015] The present invention has the following beneficial effects: 1. In the present invention, when the swinging component and the lifting component are operating, the second sliding block drives the wind blocking plate to reach a specified position and then complete rotation. Thus, when the fan blade blows air on one side, due to the blocking of the wind blocking plate, a part of the air flow will move in the reverse direction and then blow in the reverse direction at the air inlet of the main body. Therefore, when the motor rotates forward, it can generate a part of the reverse air flow blowing towards the air inlet, thereby reducing the situation that after the air conditioner is used for too long, a large amount of dust adheres to the filter screen at the air inlet, resulting in the difficulty of the air flow generated by the reverse rotation of the motor to clean the dust that has adhered for a long time and accumulated, and improving the cleaning rate of the motor after flipping.

[0016] 2. In the present invention, during the movement of the pushing component, since the gap between the return spring and the rotating rod will change, the second sliding block can rotate better after the wind blocking plate on its top contacts the second arc-shaped plate due to the increase in the gap during the sliding process. After the second sliding block slides to the specified position, the distance between the second sliding block and the rotating rod is restored, so that the return spring pushes the extrusion block to contact the outer surface of the second sliding block to fix the second sliding block, reducing the situation that after the second sliding block moves to the specified position, the wind blocking plate shakes due to the blowing of the wind and then contacts the fan blade, improving the stability of the device during operation, and thus improving the efficiency during operation.

[0017] 3. In the present invention, when the fixing component and the auxiliary component are operating, they will contact the pushing plate and then push the pushing plate to slide outward inside the arc-shaped groove and stretch the spring connected to it during the continuous movement, and then contact the outer surface of the wind blocking plate to assist the rotation of the wind blocking plate, improving the rotation speed of the wind blocking plate when rotating by contacting the second arc-shaped plate, and thus reducing the situation that the second sliding block contacts the fan blade during the continuous movement due to slow rotation when the second sliding block rotates, preventing accidents when the fan blade rotates, and ensuring the overall stability of the device during operation.

[0018] 4. In the present invention, during the sliding process of the sliding block 1 sliding inside the arc groove 1, its side wall assembly will gradually contact the pushing member, and the side wall of the sliding block 1 will contact the non-protruding end of the L-shaped rod to promote its rotation. Thereafter, after the sliding block 1 moves into the arc groove 1, the end located at the protruding portion of the L-shaped rod will be stuck by the sliding block 1. Thereafter, during the resetting process of the sliding block 1, the protruding portion of the L-shaped rod will be rotated, so that the other end of the L-shaped rod will rotate downward and contact the sliding block 1, thereby assisting the sliding block 1 in resetting, reducing the situation in which the sliding block 1 is blocked by the protruding portion of the L-shaped rod during the resetting process and then partially tilted, thereby affecting the resetting, thereby ensuring the stability of the device during operation and improving the efficiency of operation.

During the downward movement of the first connecting rod 213, the sliding rod 214 will be pushed to slide downward on the side wall of one of the support frames 111.

During the downward sliding of the sliding rod 214, the second sliding block 222 will be pushed to slide inside the rotating groove through the second connecting rod 221. During the sliding process of the second sliding block 222, the wind blocking plate 223 will be driven to move synchronously. During the movement of the wind blocking plate 223.

[0033] The extrusion member includes a strip-shaped groove 312 formed inside the rotating rod 311, a return spring 313 is fixedly connected inside the strip-shaped groove 312, and an extrusion block 314 is fixedly connected to one end of the return spring 313 close to the second sliding block 222; Among them, a telescopic rod 315 is fixedly connected to the outer surface of the rotating rod 311, and a pushing strip 316 is fixedly connected to the top of the telescopic rod 315; The inner wall of the rotating rod 311 is rotatably connected to the outer surface of the second sliding block 222. One end of the rotating rod 311 away from the second sliding block 222 is rotatably connected to the inner bottom wall of the main body 1. During the rotation of the rotating rod 311, since one end of the rotating rod 311 is connected to the telescopic rod 315, therefore, the telescopic rod 315 will rotate synchronously when the rotating rod 311 rotates. When the telescopic rod 315 rotates, it will synchronously drive the pushing bar 316 located at its top to move inside the second arc-shaped groove 322.

[0034] The auxiliary assembly 32 includes a second arc-shaped plate 321 fixedly connected to the inner wall of the main body 1. An arc-shaped groove 322 is formed inside the second arc-shaped plate 321. A plurality of sliding plates 323 are slidably connected inside the arc-shaped groove 322; Among them, a plurality of springs are fixedly connected to the side wall of the sliding plate 323. One end of the plurality of springs away from the sliding plate 323 is fixedly connected to the inner wall of the second arc-shaped plate 321. During the rotation of the pushing bar 316, it will come into contact with the sliding plate 323 and then push the sliding plate 323 to slide outward inside the arc-shaped groove 322 while stretching the springs connected to it during the continuous movement.

[0035] When the air conditioner is in use, the motor 112 located on the side wall of the support frame 111 is first started. The motor 112 drives the rotating shaft 113 to rotate clockwise through its output end. During the rotation of the rotating shaft 113, the fan blades 114 located on its outer surface are driven to rotate synchronously. While the rotating shaft 113 rotates, the contraction block on its outer surface rotates clockwise, thereby contacting the side wall of the sliding block 1 211, thereby pushing the sliding block 1 211 to slide in the arc groove 1 123 inside the arc plate 1 122. During the sliding process of the sliding block 1 211, a thrust is applied to the arc spring 124 to cause it to contract. As the sliding block 1 211 continues to slide, The first part of the sliding block 211 is connected to the first part of the arc groove 123, and the second ... The sliding rod 214 slides downward on the side wall of one of the support frames 111. During the downward sliding of the sliding rod 214, the connecting rod 221 pushes the sliding block 222 to slide inside the rotating groove. During the sliding of the sliding block 222, the wind blocking plate 223 is driven to move synchronously. During the movement of the wind blocking plate 223, it contacts the inner wall of the rotating rod 311 and drives the sliding block 222 to rotate during the movement. After that, when the sliding block 1 211 is fixed, since the L-shaped rod 127 fixing the sliding block 1 211 is small, the sliding block 1 211 will gradually break away from the L-shaped rod 127. Then, due to the rapid rotation of 113, it will retract. The shrinking block rotates quickly to fix the sliding block 1 211, and then the sliding block 222 drives the wind blocking plate 223 to reach the specified position and completes the rotation. Therefore, when the air flow is blown on one side of the fan blade 114, due to the obstruction of the wind blocking plate 223, a part of the air flow will move in the opposite direction and blow the air inlet of the main body 1 in the opposite direction, so that the motor can generate part of the reverse air flow to the air inlet when rotating forward, thereby reducing the situation where a large amount of dust adheres to the filter net at the air inlet after the air conditioner has been used for too long, resulting in the air flow generated after the motor is reversed being difficult to clean the dust that has been attached for a long time and has accumulated, thereby improving the cleaning rate of the motor after it is flipped over.

[0036] During the process of the second sliding block 222 sliding inside the rotating groove, due to the reduction in the distance between the second sliding block 222 and the rotating rod 311, during the sliding process of the second sliding block 222, its outer surface will contact the side wall of the pressing block 314, thereby pushing the return spring 313 to squeeze the strip-shaped groove 312, causing the strip-shaped groove 312 to contract, and then making the return spring 313 slide into the interior of the rotating rod 311, thus increasing the gap between the return spring 313 and the rotating rod 311. As a result, during the sliding process of the second sliding block 222, due to the increase in the gap, the wind blocking plate 223 at its top can rotate better after contacting the second arc-shaped plate 321. After the second sliding block 222 slides to the designated position, the distance between the second sliding block 222 and the rotating rod 311 is restored, so that the return spring 313 pushes the pressing block 314 to contact the outer surface of the second sliding block 222, thereby fixing the second sliding block 222. This reduces the situation where the wind blocking plate 223 shakes due to the blowing of the wind after the second sliding block 222 moves to the designated position and then contacts the fan blade 114, improving the stability of the device during operation and thus enhancing the efficiency during operation.

[0037] During the process of the second sliding block 222 driving the wind blocking plate 223 to rotate, it will drive the rotating rod 311 to rotate synchronously. During the rotation of the rotating rod 311, since one end of the rotating rod 311 is connected to the telescopic rod 315, therefore, the telescopic rod 315 will rotate synchronously when the rotating rod 311 rotates. When the telescopic rod 315 rotates, it will synchronously drive the pushing strip 316 located at its top to move inside the second arc-shaped groove 322. During the rotation of the pushing strip 316, it will contact the sliding plate 323 and then, during the continuous movement, it will push the sliding plate 323 to slide outward inside the second arc-shaped groove 322 and stretch the spring connected to it. Then it will contact the outer surface of the wind blocking plate 223 to assist the rotation of the wind blocking plate 223, increasing the speed at which the wind blocking plate 223 rotates by contacting the second arc-shaped plate 321 during rotation. As a result, it reduces the situation where the second sliding block 222 contacts the fan blade 114 during the subsequent movement due to slow rotation during the rotation of the second sliding block 222, preventing unexpected situations during the rotation of the fan blade 114 and ensuring the overall stability of the device during operation.

[0038] During the process of the first sliding block 211 sliding inside the first arc-shaped groove 123, its side wall will gradually come into contact with the pusher, and then gradually enter the inside of the first arc-shaped groove 123 during the continuous movement. During the process of the first sliding block 211 entering the inside of the first arc-shaped groove 123, the side wall of the first sliding block 211 will contact the non-protruding end of the L-shaped rod 127 to push it to rotate. After the first sliding block 211 moves into the inside of the first arc-shaped groove 123, the end of the L-shaped rod 127 located at the protruding part will jam the first sliding block 211. Then, due to the small contact area between the protruding part and the first sliding block 211, during the process of the first sliding block 211 resetting, the protruding part of the L-shaped rod 127 will rotate, causing the other end of the L-shaped rod 127 to rotate downward to contact the first sliding block 211 to assist the first sliding block 211 in resetting, reducing the situation where the first sliding block 211 is blocked by the protruding part of the L-shaped rod 127 during the resetting process and partially warps, thereby affecting the resetting, and thus ensuring the stability of the device during operation and improving the operation efficiency.
