Description

Technical Field

[0001] The invention relates to the technical field of central air conditioners, in particular to a pipe for a central air conditioner with the function of collecting and processing dust. Background Art

[0002] Central air conditioning refers to large-scale air conditioning equipment composed of one or more cold and heat source systems and multiple air conditioning systems. It can control the temperature inside multiple rooms at the same time through a host, introduce new air into the room, and help improve the air environment;

[0003] The Chinese publication number cited is CN113063225A. The patent discloses a duct for a central air conditioner with a dust collection and processing function, including a dust removal duct body, a filter screen is fixedly installed inside the dust removal duct body, a fixed plate is fixedly installed inside the dust removal duct body, a through hole is opened on the left side of the fixed plate, a coaxial wheel is movably installed inside the fixed plate, and a magnetic isolation plate is fixedly installed on the top of the coaxial wheel;

[0004] When the central air conditioner is in use, it needs pipes to transport gas to ventilate the room. However, after the pipes are used for a long time, a lot of dust will adhere to the inner wall of the pipes. During the use of the central air conditioner, the dust will enter the room, causing the indoor air to deteriorate and damaging human health. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a duct for a central air conditioner with a dust collection and treatment function to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions: a central air-conditioning device with a dust collection and processing function, including a central air-conditioning device, which cools a certain space when in use, and then draws outside air through an intake pipe and delivers it to a certain space when the air needs to be improved, and when the air flows through the intake pipe, the filter bag filters the dust in the air and then temporarily stores it on the filter bag, and when the air flows through the filter bag, the filter bag is driven to shrink into the intake pipe, the outer wall of the central air-conditioning device is plugged with an intake pipe, the outer wall of the intake pipe is rotatably connected to a bearing, the outer wall of the bearing is fixedly connected to a connecting rod, the outer wall of the connecting rod is fixedly connected to a rotating tube, and the outer wall of the rotating tube is fixedly connected to a filtering mechanism;

[0007] The filtering mechanism comprises:

[0008] The filter bag has a hole on its outer wall, and the filter bag is fixedly connected to the hole position of the filter bag. The filter bag will filter the dust in the air and then temporarily store it on the filter bag, ensuring the filtration of dust in the air and preventing dust from entering the room and causing the indoor air to deteriorate, which will damage human health. When the airflow passes through the filter bag, it will drive the filter bag to shrink into the air inlet pipe. The shrinkage of the filter bag forms a bag-like shape, and then the dust will be gathered inside the bag-like shape of the filter bag, ensuring the gathering of dust and ensuring that the other positions of the filter bag can filter the dust normally while the airflow passes through. The rotation of the horizontal tube is combined with the Bernoulli principle, and the airflow is prevented from passing through the horizontal tube into the rotating tube under the flow of gas driven by pressure, preventing the external air from directly entering the air inlet pipe through the horizontal tube.

[0009] The cross pipe is fixedly connected to the outer wall of the rotating pipe. The rotation of the cross pipe drives the dust inside the intake pipe to be discharged to the outside by utilizing the pressure, thereby cleaning the dust on the inner wall of the intake pipe and avoiding the accumulation of dust on the inner wall of the intake pipe. The gear will also drive the impact block during the rotation. The impact block and the protrusion block will collide during the rotation, which will drive the intake pipe to vibrate. The intake pipe will cause the dust adhered to the inner wall of the intake pipe to fall off during the vibration, thereby cleaning the dust adhered to the inner wall of the intake pipe. After falling, the dust is discharged by the flow of airflow in the cross pipe, thereby discharging the dust.

[0010] Preferably, there are three transverse tubes, and the transverse tubes are connected to the interior of the rotating tube, and part of the rotating tube is also located in the air intake pipe.

[0011] Preferably, the outer wall of the bearing is fixedly connected with circular teeth, and the outer wall of the central air-conditioning device is fixedly connected with a motor, and the kinetic energy generated by the rotating tube during rotation is used to drive the rotation of the pull rope. The gravity block at the end of the pull rope is set, so centrifugal force is generated during the rotation process. The pull rope is driven to move in the limit ring under the pull of the centrifugal force, and then the filter bag is pulled out, which has the effect of guiding the filter bag to leak out. After the filter bag is extended, the dust adhered to the inner wall of the filter bag will fall off, and the vibration generated during the collision between the protruding block and the impact block will be transmitted to the filter bag. The vibration will cause the dust on the filter bag to fall further, ensuring the cleaning of the dust on the filter bag and avoiding the filter bag being blocked by dust.

[0012] Preferably, the outer wall of the motor is rotatably connected to a gear, and the gear is meshed with circular teeth. When the motor is powered on and started, the motor drives the gear to rotate, and the meshing of the gear and the circular teeth drives the rotation of the bearing. Then the connecting rod is respectively connected to the rotating tube and the bearing. When the rotating tube rotates, it drives the rotation of the cross tube. During the rotation of the cross tube, the air flow velocity at the outer circle position of the cross tube is greater than the air flow velocity at the inner position of the rotating tube.

[0013] Preferably, a spring is fixedly connected to the outer wall of the gear, and an impact block is fixedly connected to the outer wall of the spring.

[0014] Preferably, two protruding blocks are fixedly connected to the outer wall of the air intake pipe at positions on both sides of the impact block, and the protruding blocks are in active contact with the impact block.

[0015] Preferably, a cleaning mechanism is fixedly connected to the outer wall of the rotating tube, and the cleaning mechanism comprises a limiting ring, and the limiting ring is fixedly connected to the outer wall of the rotating tube.

[0016] Preferably, a pulling rope is inserted into the inner wall of the limiting ring. When the central air-conditioning device needs to suck in air from the outside, the force of the air sucked by the central air-conditioning device is relatively large, so the filter bag will be driven to shrink into the air inlet pipe under the suction. Then, when the central air-conditioning device stops sucking in air from the outside, the suction force disappears, so the rotating tube will drive the rotation of the pulling rope during rotation. The gravity block at the end of the pulling rope is set, so centrifugal force is generated during the rotation process. One end of the pulling rope is fixedly connected to the inner wall of the filter bag, and the other end of the pulling rope is fixedly connected to the gravity block.

[0017] The present invention provides a central air conditioner with a dust collecting and processing pipe.

[0018] Beneficial effects:

[0019] 1. The central air conditioner uses a pipe with the function of collecting and processing dust. The dust in the air will be filtered through the filter bag, and then temporarily stored on the filter bag, ensuring the filtration of dust in the air and preventing dust from entering the room and causing the indoor air to deteriorate, damaging human health. When the airflow passes through the filter bag, it will drive the filter bag to shrink into the air inlet pipe. The contraction of the filter bag forms a bag-like shape, and then the dust will be gathered inside the filter bag, ensuring the gathering of dust and ensuring the normal dust filtration at other positions of the filter bag while the airflow passes. The rotation of the horizontal tube is combined with the Bernoulli principle. Under the pressure-driven flow of gas, the airflow is prevented from passing through the horizontal tube into the rotating tube, preventing external air from directly entering the air inlet pipe through the horizontal tube.

[0020] 2. The central air conditioner uses a pipe with the function of collecting and processing dust. Through the rotation of the horizontal pipe, the pressure is used to drive the dust inside the intake pipe to be discharged to the outside, which has the effect of cleaning the dust on the inner wall of the intake pipe and avoiding the accumulation of dust on the inner wall of the intake pipe. The gear will also drive the impact block during the rotation process. The impact block and the protrusion block will collide during the rotation, and the intake pipe will vibrate during the collision. The intake pipe will make the dust adhered to the inner wall of the intake pipe fall off during the vibration process, which has the effect of cleaning the dust adhered to the inner wall of the intake pipe. After the dust falls, the flow of airflow in the horizontal pipe drives the dust to be discharged, which has the effect of discharging dust.

[0021] 3. The central air conditioner uses a pipe with the function of collecting and processing dust. The kinetic energy generated by the rotating tube during rotation drives the rotation of the pulling rope. The gravity block at the end of the pulling rope is set, so centrifugal force is generated during the rotation process. The pulling rope is driven by the centrifugal force to move in the limit ring, and then the filter bag is pulled out, which plays an effect of guiding the filter bag to leak out. After the filter bag is extended, the dust adhered to the inner wall of the filter bag will fall off, and the vibration generated during the collision between the protruding block and the impact block will be transmitted to the filter bag. The vibration will cause the dust on the filter bag to fall further, ensuring the cleaning of the dust on the filter bag and avoiding the filter bag being blocked by dust.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Embodiment 1

[0034] See also Figure 1-6 The present invention provides a technical solution: a central air conditioner with a dust collecting and processing function, comprising a central air conditioner 1, an air inlet pipe 2 is plugged into the outer wall of the central air conditioner 1, a bearing 3 is rotatably connected to the outer wall of the air inlet pipe 2, a connecting rod 4 is fixedly connected to the outer wall of the bearing 3, a rotating tube 5 is fixedly connected to the outer wall of the connecting rod 4, and a filtering mechanism 6 is fixedly connected to the outer wall of the rotating tube 5;

[0035] The filtering mechanism 6 comprises:

[0036] The filter bag 61 and the outer wall of the rotating tube 5 are provided with holes, and the filter bag 61 is fixedly connected to the hole position of the filter bag 61. The filter bag 61 will filter the dust in the air, and then temporarily store it on the filter bag 61, ensuring the filtration of dust in the air, and preventing dust from entering the room and causing the indoor air to deteriorate, which will damage human health. When the airflow passes through the filter bag 61, it will drive the filter bag 61 to shrink into the air inlet pipe 2, and the shrinkage of the filter bag 61 forms a bag-like shape, and then the dust will be gathered inside the bag of the filter bag 61, ensuring the gathering of dust, ensuring that the other positions of the filter bag 61 can filter the dust normally while the airflow passes through. The rotation of the cross tube 62 is combined with the Bernoulli principle, and the pressure drives the flow of gas to prevent the airflow from passing through the cross tube 62 and entering the rotating tube 5, thereby preventing the external air from directly entering the air inlet pipe 2 through the cross tube 62.

[0037] The transverse tube 62 is fixedly connected to the outer wall of the rotating tube 5 .

[0038] There are three transverse tubes 62, and the transverse tube 62 is connected to the inside of the rotating tube 5. Part of the rotating tube 5 is also located in the air intake pipe 2. The rotation of the transverse tube 62 uses pressure to drive the dust inside the air intake pipe 2 to be discharged to the outside, which has the effect of cleaning the dust on the inner wall of the air intake pipe 2 and avoiding the accumulation of dust on the inner wall of the air intake pipe 2. The gear 64 will also drive the impact block 10 during the rotation. The impact block 10 and the protruding block 8 will collide during the rotation, which will drive the air intake pipe 2 to vibrate. The air intake pipe 2 will cause the dust adhered to the inner wall of the air intake pipe 2 to fall off during the vibration, which has the effect of cleaning the dust adhered to the inner wall of the air intake pipe 2. After the dust falls, it is driven to be discharged by the flow of airflow in the transverse tube 62, which has the effect of discharging dust.

[0039] The outer wall of the bearing 3 is fixedly connected with a circular tooth 65 , and the outer wall of the central air conditioning device 1 is fixedly connected with a motor 63 .

[0040] The outer wall of the motor 63 is rotatably connected to a gear 64 , and the gear 64 is meshed with a circular tooth 65 .

[0041] A spring 9 is fixedly connected to the outer wall of the gear 64 , and an impact block 10 is fixedly connected to the outer wall of the spring 9 .

[0042] Two protruding blocks 8 are fixedly connected to the outer wall of the air inlet pipe 2 at positions on both sides of the impact block 10 , and the protruding blocks 8 are in active contact with the impact block 10 .

[0043] When in use, the central air-conditioning device 1 cools down a certain space, and when the air needs to be improved, it will draw in external air through the air intake pipe 2 and transport it to a certain space. When the airflow passes through the air intake pipe 2, the filter bag 61 will filter the dust in the air, and then temporarily store it on the filter bag 61. When the airflow passes through the filter bag 61, it will drive the filter bag 61 to shrink into the air intake pipe 2. The motor 63 is powered on and started, and the motor 63 drives the gear 64 to rotate. The engagement of the gear 64 and the circular tooth 65 will drive the rotation of the bearing 3, and then the connecting rod 4 is respectively connected to the rotating tube 5 and the bearing 3. The rotating tube 5 will drive the rotation of the cross tube 62 when it rotates. During the rotation of the cross tube 62, the airflow velocity at the outer circle position of the cross tube 62 is greater than the airflow velocity at the inner position of the rotating tube 5. According to Bernoulli's principle, the greater the airflow velocity, the better. The smaller the pressure, the pressure inside the rotating tube 5 squeezes the gas to be discharged toward the outside of the cross tube 62. When the pressure drives the flow of gas, the airflow is prevented from passing through the cross tube 62 and entering the rotating tube 5. When the central air-conditioning device 1 stops sucking air from the outside, the rotation of the cross tube 62 uses the pressure to drive the dust inside the intake pipe 2 to be discharged to the outside. The gear 64 will also drive the rotation of the spring 9 and the impact block 10 during the rotation process. The elastic length of the spring 9 makes the impact block 10 located between the two protruding blocks 8. When the gear 64 drives the impact block 10 to rotate, the impact block 10 and the protruding block 8 will collide. During the collision, the intake pipe 2 will be driven to vibrate. During the vibration of the intake pipe 2, the dust adhered to the inner wall of the intake pipe 2 will fall off. After the dust falls, the flow of air in the cross tube 62 drives the dust to be discharged.

[0044] Embodiment 2

[0045] See also Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0046] The outer wall of the rotating tube 5 is fixedly connected with a cleaning mechanism 7 . The cleaning mechanism 7 includes a limiting ring 72 . The limiting ring 72 is fixedly connected to the outer wall of the rotating tube 5 .

[0047] The pull rope 71 is inserted into the inner wall of the limiting ring 72, and the kinetic energy generated by the rotating tube 5 during rotation is used to drive the rotation of the pull rope 71. The gravity block 73 at the end of the pull rope 71 is set, so centrifugal force is generated during the rotation process. The pull of the centrifugal force will drive the pull rope 71 to move in the limiting ring 72, and then the filter bag 61 will be pulled out, which has the effect of guiding the filter bag 61 to leak out. After the filter bag 61 is extended, the dust adhered to the inner wall of the filter bag 61 will fall off, and the vibration generated during the collision between the protruding block 8 and the impact block 10 will be transmitted to the filter bag 61. The vibration will cause the dust on the filter bag 61 to fall further, ensuring the cleaning of the dust on the filter bag 61 and avoiding the filter bag 61 being blocked by dust. One end of the pull rope 71 is fixedly connected to the inner wall of the filter bag 61, and the other end of the pull rope 71 is fixedly connected to the gravity block 73.

[0048] During use, because the force of the air sucked by the central air-conditioning device 1 is relatively large when the central air-conditioning device 1 needs to suck the outside air, the suction will drive the filter bag 61 to shrink into the air inlet pipe 2. Then, when the central air-conditioning device 1 stops sucking the outside air, because the suction force disappears, the rotating tube 5 will drive the rotation of the pull rope 71 during rotation. The gravity block 73 at the end of the pull rope 71 is set, so centrifugal force is generated during the rotation process. Under the pull of the centrifugal force, the pull rope 71 is driven to move in the limit ring 72, and then the filter bag 61 is pulled out. After the filter bag 61 is extended, the dust adhered to the inner wall of the filter bag 61 will fall off, and the vibration generated during the collision between the protrusion block 8 and the impact block 10 will be transmitted to the filter bag 61, and the vibration will cause the dust on the filter bag 61 to fall further.
