Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a purification device for a new type of combined air conditioner unit. Background Art

[0002] A combined air conditioner is an air conditioner unit composed of a combination of multi-functional sections of purifiers, and is commonly used in the air purification systems of various clean workshops, such as industrial electronics factories, precision machinery manufacturing factories, textile workshops and other occasions.

[0003] During the use of the combined air conditioner, since the outside air is cooled by the outdoor unit and then discharged into the room, in order to prevent dust from entering the room, a filter screen is provided at the air inlet of the outdoor unit. However, although the existing filter screen can filter some dust, there is still some dust that enters the interior of the outdoor unit, and then enters the workshop along with the air flow, resulting in air pollution in the workshop. Moreover, during long-term use, dust will also adhere to the fan blades, so that when people replace the filter screen later, they also need to clean the fan, which is rather troublesome. At the same time, since some workshops need to maintain dryness, some existing outdoor units are provided with a dehumidification mechanism to dehumidify the gas entering the workshop. Since most of the existing dehumidification uses a dehumidifying agent to adsorb moisture, the dehumidifying agent that first comes into contact with the gas has a larger adsorption amount, and the side farther away from the air outlet has a smaller adsorption amount of moisture. When replacing the dehumidifying agent each time, a part of the dehumidifying agent cannot reach its maximum absorption level sufficiently, resulting in waste of the dehumidifying agent. Therefore, it is necessary to design a new type of purification device for a combined air conditioner unit to solve the above problems. Summary of the Invention

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

A horizontal pipe 39 is communicated with the left side of the housing 1. A dust removal switching assembly is provided in the housing 1. The dust removal switching assembly includes a rectangular frame 24 provided in the housing 1. The left and right inner walls of the rectangular frame 24 are jointly rotatably connected to a switching rod 16. Fixing plates 33 are fixedly connected to the upper and lower ends of the switching rod 16. Thick rods 35 are rotatably connected to the right sides of the two fixing plates 33.

The two thick rods 35 and the corresponding fixing plates 33 are elastically connected by torsion springs 34. Thus, when the incomplete gear 37 meshes with the upper first gear 36, the thick rod 35 will drive the disc 7 and the electrostatic bar 9 to rotate. When the incomplete gear 37 does not mesh with the first gear 36, at this time, under the action of the torsion spring 34, the thick rod 35 drives the disc 7 and the electrostatic bar 9 to rotate in the reverse direction.

The L-shaped rod 31 is made of iron metal material. When the first electromagnet 29 is energized, it generates an attractive force on the L-shaped rod 31. The front inner wall of the shell 1 is rotatably connected to a rotating rod 4. The front side of the rotating rod 4 extends to the outside. The rotating rod 4 and the output shaft of the driving motor 22 are both provided with a second bevel gear 38. The lead screw 5 located above extends to the outside. The rotating rod 4 and the lead screw 5 are connected through a first transmission assembly 3. The first transmission assembly 3 includes a first sprocket arranged on the rotating rod 4 and the lead screw 5. The two first sprockets are connected through a first chain transmission.

[0036] Among them, the left side of the transverse tube 39 is fixedly connected with a dehumidification box 10, and the left side of the dehumidification box 10 is connected with an air outlet pipe 20. A cylinder 45 is arranged in the dehumidification box 10, and two grids 42 are arranged in the cylinder 45. Activated carbon is arranged between the two grids 42. The front inner wall of the dehumidification box 10 is rotatably connected with a cross bar 13, and the left side of the switching rod 16 extends to the outside. Two connecting blocks 14 are fixedly connected to the left side of the shell 1, and a transmission rod 12 is rotatably connected to the two connecting blocks 14. The transmission rod 12 and the switching rod 16 are both provided with a first bevel gear 15. The transmission rod 12 and the cross bar 13 are connected through the second transmission assembly 11. The second transmission assembly 11 includes a second sprocket arranged on the transmission rod 12 and the cross bar 13. The two second sprockets are connected through a second chain transmission, annular grooves are provided on the left and right sides of the cylinder 45, and second electromagnets 41 are provided on the inner walls of the adjacent sides of the two annular grooves. Sealing blocks 40 are slidably connected in the two annular grooves, and the two sealing blocks 40 are elastically connected to the adjacent sides of the second electromagnets 41 through a second spring. Sealing rings are provided on the opposite sides of the two sealing blocks 40, so as to ensure the sealing between the cylinder 45 and the air outlet pipe 20 and the cross pipe 39. A timer and a controller are provided. When the running time reaches the timing time of the timer, the timer will transmit a signal to the controller, and the controller controls the pneumatic rod 44 to contract first and then stretch, and at the same time, the first electromagnet 29 and the second electromagnet 41 are energized for a period of time.

[0037] The functional principle of the present invention can be explained through the following operation mode: first, the outlet pipe 20 is connected to the main machine in the factory, and then the driving motor 22 is controlled to operate, so that the fan 23 rotates, so that the external air enters the housing 1 through the filter, and then is injected into the factory through the outlet pipe 20. When the air conditioning unit is running, the electrostatic generator 2 will be synchronously operated. Since the conductive rod 18 located at the front side is in contact with the two conductive blocks 19 at this time, the electrostatic rod 9 located at the top is energized and operated;

[0038] When the electrostatic rod 9 is powered on, static electricity will be generated on the electrostatic rod 9. At this time, the gas entering the housing 1 will be initially filtered through the filter, and some fine dust will enter the housing 1. According to the characteristic that static electricity attracts small particles, the fine dust in the air will be adsorbed on the electrostatic rod 9 located above.

[0039] When the fan 23 is running, the incomplete gear 37 will rotate. When the incomplete gear 37 is meshed with the first gear 36, the first gear 36 will drive the thick rod 35 and the disc 7 located above to rotate, thereby causing the electrostatic rod 9 located above to rotate. When the incomplete gear 37 is not meshed with the first gear 36, the thick rod 35 drives the disc 7 and the electrostatic rod 9 to rotate in the opposite direction under the action of the torsion spring 34, so that the electrostatic rod 9 can more comprehensively absorb the dust in the gas entering the housing 1.

[0040] After a period of time, when the running time of the timer is reached, the timer will transmit a signal to the controller. The controller controls the pneumatic rod 44 to contract first and then stretch, and controls the first electromagnet 29 and the second electromagnet 41 to be energized for a period of time. When the first electromagnet 29 is energized for a period of time, it will exert an attractive force on the corresponding L-shaped rod 31, causing the two L-shaped rods 31 to move to the right and move away from the electrostatic rod 9 located below;

[0041] When the pneumatic rod 44 contracts, it will cause the moving block 26 to drive the rack 17 to move backward, so that the second gear 43 drives the switching rod 16 to rotate, thus changing the positions of the two electrostatic rods 9. When the switching rod 16 rotates, the two conductive rods 18 will be separated from the conductive block 19, so that the static electricity on the electrostatic rod 9 will slowly dissipate. After the positions of the two electrostatic rods 9 are exchanged, the electrostatic rod 9 rotated to the upper side is energized and operates, and the dust on the electrostatic rod 9 rotated to the lower side will slowly dissipate, so that the dust on the electrostatic rod 9 will fall to the inner bottom of the housing 1 (a collection box can be placed at the inner bottom of the housing 1 so that the falling dust can fall into the collection box for subsequent cleaning by the staff);

[0042] When the pneumatic rod 44 stretches, it will cause the moving block 26 to drive the rack 17 to move forward. Since a one-way bearing is provided between the second gear 43 and the switching rod 16, the rotation of the second gear 43 will not drive the switching rod 16 to rotate at this time;

[0043] After a period of time, the first electromagnet 29 will be de-energized, causing the two L-shaped rods 31 to move back, so that the multiple brush hairs 32 move to the upper and lower sides of the electrostatic rod 9. When the drive motor 22 operates, the second bevel gear 38 drives the rotating rod 4 to rotate, and then the two lead screws 5 are driven by the first transmission assembly 3 and the third transmission assembly 27 to rotate, so that the two sliders 28 drive the multiple brush hairs 32 to move back and forth to clean the electrostatic rod 9 rotated to the lower side;

[0044] The gas entering the housing 1 will enter the cylinder 45 through the horizontal pipe 39, and then be injected into the host through the air outlet pipe 20 and finally into the workshop. At this time, the activated carbon in the cylinder 45 can dehumidify the gas, so that the gas entering the workshop remains in a dry state;

[0045] After the two second electromagnets 41 are energized, an attractive force will act on the two sealing blocks 40, causing the two sealing blocks 40 to move relative to each other, so that the two sealing blocks 40 move away from the air outlet pipe 20 and the horizontal pipe 39. When the switching rod 16 rotates, it will drive the transmission rod 12 to rotate, and then drive the cross bar 13 to rotate through the second transmission assembly 11, so that the cylinder 45 rotates 180 degrees. Furthermore, the positions of the activated carbon on the left and right sides of the cylinder 45 are exchanged, ensuring that each activated carbon can fully exert its adsorption property;

[0046] After a period of time, the second electromagnet 41 will be de-energized. At this time, under the elastic action of the second spring, the two sealing blocks 40 will move away from each other, so that the two sealing blocks 40 will tightly squeeze against the adjacent sides of the air outlet pipe 20 and the horizontal pipe 39 again, so that the gas in the housing 1 enters the main machine through the horizontal pipe 39, the cylinder 45 and the air outlet pipe 20, and then is injected into the workshop.

[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
