Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically an automatic cleaning device for air conditioner heat sink production. Background Technology

[0002] Air conditioning fins are the core components of air conditioning systems used for air heat exchange. They are usually composed of densely arranged metal fins such as aluminum fins and copper tubes. Their main function is to increase the heat dissipation area to improve heat exchange efficiency. When the refrigerant flows inside the copper tubes, heat is conducted to the fins through the copper tubes. After the fins come into contact with the air, heat exchange is completed, thereby achieving cooling or heating.

[0003] As disclosed in CN219880691U, a central air conditioning radiator cleaning device relates to the field of cleaning technology. It includes a housing for cleaning radiators, a protective box fixed to one side of the housing, a main motor fixed inside the protective box, a female gear fixed to the output shaft of the main motor, a screw rotating inside the housing, a transmission rod fixed to one end of the screw, a female gear fixed to the transmission rod, a moving block threaded onto the screw, a positioning rod rotating inside the housing, a moving plate fixed to the lower end of the moving block, a pair of fixed blocks fixed to the lower end of the moving plate, and a first synchronous motor fixed inside each fixed block. A brush bucket is fixed to the output shaft of each of the first synchronous motors.

[0004] Although it achieves the ability to clean both sides of the heat sink simultaneously by adding a pair of brush buckets, making the cleaning process simpler and more efficient, by adding a pair of fans, the heat sink can be dried directly after cleaning, without the need for drying again.

[0005] However, this does not solve the problem that existing cleaning devices of this type are generally not conducive to the automatic conveying and cleaning of air conditioner condenser fins during use, are not convenient to tilt and adjust the cleaning angle of the air conditioner condenser fins, thus affecting the cleaning effect of the air conditioner condenser fins, and are not convenient to use the cleaning device to dry the air conditioner condenser fins by moving back and forth, thus affecting the drying efficiency of the air conditioner condenser fins.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] An automatic cleaning device for air conditioner heat exchanger production includes a water storage tank and a cleaning rack. The cleaning rack is installed at the top of the water storage tank. A conveyor rack is installed inside the cleaning rack and extends to the outside of the cleaning rack. A servo motor is installed on the outer wall of the conveyor rack. A conveyor roller is installed at the output end of the servo motor and extends into the interior of the conveyor rack. The conveyor roller is movably connected to the conveyor rack. A conveyor mesh chain is fitted on the surface of the conveyor roller. A support roller is movably installed inside the conveyor rack on the side away from the conveyor roller, and the conveyor mesh chain extends to the surface of the support roller. A connecting frame is installed on the outer wall of the cleaning rack above the conveyor mesh chain. A water pump is installed on the outer wall of the water storage tank. A water outlet pipe is installed on the outer wall of the water pump and extends into the interior of the water pump.

[0009] Optionally, a water supply pipe is installed on the outer wall of the outlet pipe, and the water supply pipe extends into the interior of the outlet pipe. Connecting pipes are symmetrically installed on the outer wall of the water supply pipe, and the connecting pipes extend into the interior of the water supply pipe. Three sets of water inlet pipes with equal spacing are installed on the outer wall of each connecting pipe, and one end of each water inlet pipe extends into the interior of the connecting pipe.

[0010] Optionally, a fixed frame is installed on the outer wall of the cleaning rack on one side of the water inlet pipe. A movable reversing sleeve is installed at the bottom of the fixed frame, and the other end of the water inlet pipe extends into the interior of the movable reversing sleeve. A spray pipe is movably installed at the end of the movable reversing sleeve away from the water inlet pipe, and the spray pipe extends into the interior of the cleaning rack and is movably connected to the cleaning rack.

[0011] Optionally, multiple sets of nozzles with equal spacing are installed on the outer wall of the spray pipe, and a stepper motor is installed on the outer wall of the cleaning rack on one side of the spray pipe.

[0012] Optionally, each stepper motor is equipped with a worm gear at its output end, and a worm wheel is fitted on the surface of the spray pipe on one side of the worm gear, with the worm gear and the worm wheel meshing together.

[0013] Optionally, a limit frame is installed at the top of the connecting frame, and a power motor is installed at the top of the limit frame.

[0014] Optionally, the output end of the power motor is equipped with a rotating shaft, and the rotating shaft extends to the outside of the limiting frame, and a rocker arm is fitted on the surface of the rotating shaft.

[0015] Optionally, a drive shaft is mounted at the bottom end of the rocker arm, and a sliding wheel is movably fitted onto the surface of the drive shaft.

[0016] Optionally, a groove is provided at the top of the connecting frame on one side of the sliding wheel, and the groove is slidably connected to the sliding wheel. A drive frame is slidably installed inside the connecting frame below the limiting frame.

[0017] Optionally, two sets of limiting wheels are symmetrically installed on the outer wall of the drive frame, and the limiting wheels are slidably connected to the connecting frame. Three sets of drying fans with equal spacing are installed at the bottom of the drive frame.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the cleaning device not only realizes the automatic conveying and cleaning of the air conditioner heat exchanger, but also facilitates the tilting adjustment of the cleaning angle of the air conditioner heat exchanger, improves the efficiency of batch cleaning of the air conditioner heat exchanger, facilitates the convenient reciprocating movement of the cleaning device to dry the air conditioner heat exchanger, and facilitates multi-position drying of the air conditioner heat exchanger, thus improving the drying efficiency of the air conditioner heat exchanger.

[0019] A servo motor drives a conveyor roller to rotate, which in turn drives a conveyor chain to move. The conveyor chain then moves the air conditioning radiator fins. When the radiator fins are positioned below multiple sets of nozzles, a water pump delivers water from the storage tank to two connecting pipes via an outlet pipe. These connecting pipes then deliver water through multiple inlet pipes and a movable reversing sleeve to the spray pipes, facilitating easy cleaning of the radiator fins via the multiple nozzles. The cleaned radiator fins are then conveyed by the conveyor chain to below multiple drying fans, which are activated to dry the fins. A stepper motor drives a worm gear to rotate, which in turn drives a worm wheel, which in turn drives the spray pipes. The movable reversing sleeve provides support for the spray pipes, which in turn rotates the multiple nozzles, allowing for easy adjustment of the cleaning angle. This system enables automatic conveying and cleaning of the air conditioning radiator fins, facilitates tilting adjustment of the cleaning angle, and allows for continuous conveying and discharge of the radiator fins, thus improving the efficiency of batch cleaning.

[0020] The motor drives the rotating shaft to rotate, which in turn drives the rocker arm to rotate. The rocker arm drives the drive shaft to rotate, which in turn drives the sliding wheel to rotate. The sliding wheel slides inside the sliding groove to facilitate the reciprocating movement of the drive frame. The limit wheel slides on the surface of the connecting frame to provide sliding support for the drive frame. The drive frame drives three sets of drying fans to move and turn on, facilitating convenient reciprocating drying of the air conditioner heat sink. This enables the cleaning device to conveniently dry the air conditioner heat sink in multiple locations, improving the efficiency of drying the air conditioner heat sink and enhancing the convenience of cleaning the air conditioner heat sink.
