Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment and unit technology, and in particular to an air conditioning unit that combines electrostatic adsorption and deep purification of the filter. Background Technology

[0002] With the increasing demands for air quality in modern building environments, air conditioning units not only need to have temperature and humidity control functions, but also need to integrate efficient air purification technology. Air purification technology or devices can filter and adsorb impurities, dust and bacteria in the air, ensuring that the air input into the area is clean to meet the needs of production work.

[0003] Traditional modular air conditioning units typically employ single filtration or electrostatic adsorption technologies. For example, patent application CN 222747429 U discloses a utility model of a "modular air conditioning unit" that combines a filter with electrostatic adsorption. However, the two are simply arranged in series. The particulate matter capture efficiency of the electrostatic adsorption component is greatly affected by airflow distribution, and the single-zone design makes it difficult to handle environments with high concentrations of pollutants. Furthermore, the planar structure of the filter results in a small effective filtration area, further limiting its purification capacity. Although the filter assembly is designed to be detachable, it lacks self-cleaning functionality and is prone to clogging after long-term use, failing to address the performance degradation caused by filter dust accumulation. Therefore, it fails to fully utilize the synergistic purification effect, resulting in poor synergy. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an air conditioning unit that combines electrostatic adsorption with deep purification via a filter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An air conditioning unit that combines electrostatic adsorption and deep purification through a filter includes a unit housing. Two sets of fixing grooves are fixedly connected inside the unit housing, and an insulating partition is fixedly connected between the two sets of fixing grooves. A honeycomb electrode plate is disposed in the fixing groove on the left side, and a support rod is fixedly connected in the fixing groove on the right side. Several needle-shaped electrodes are fixedly connected to the end of the support rod, and a metal mesh electrode is disposed on the side of the needle-shaped electrodes away from the support rod.

[0007] The unit housing is also fixedly connected to a support groove. A HEPA filter is provided on one side of the support groove, and an activated carbon adsorption layer is provided on one side of the HEPA filter. Electrode plates are fixedly connected to both sides of the inner wall of the support groove, and an electrostatic filter is snapped into the electrode plate.

[0008] Preferably, a corrugated filter is provided on one side of the outer wall of the support groove. The corrugated filter adopts a pleated corrugated structure. A guide plate is inclinedly provided between the corrugated filter and the fixed groove. A purging component is provided on the side of the support groove away from the corrugated filter.

[0009] Preferably, the purging assembly includes a support vertical plate located inside the unit housing, an axial flow fan is provided on the support vertical plate, the output end of the axial flow fan is connected to a purging duct, and the purging duct is connected to the inner wall of the unit housing through two Y-shaped support frames.

[0010] Preferably, the end of the purge duct away from the axial flow fan extends above the electrostatic layer filter and is fixedly connected to a flow duct. The flow duct communicates with the interior of the purge duct. The outer wall of the flow duct has several oblique spray holes. A solenoid valve is provided at the end of the purge duct near the axial flow fan.

[0011] Preferably, ultraviolet lamps are provided on both sides of the outer wall of the electrostatic layer filter, and the outer wall of the electrostatic layer filter is coated with a nano-coating.

[0012] Preferably, the outer walls of the ultraviolet lamp group, the fixing groove, and the electrostatic filter are all provided with power-conducting terminals, and the output terminals of the power-conducting terminals are connected to the external power supply terminal of the unit housing.

[0013] Preferably, the inner wall of the unit housing is provided with a discharge port, and a dust collection box is provided inside the discharge port. The dust collection box is located below the electrostatic filter and has a snap-fit ​​opening on its outer wall.

[0014] The beneficial effects of this utility model are:

[0015] This air conditioning unit employs a dual-zone electrostatic adsorption system consisting of honeycomb electrode plates, needle electrodes, and metal mesh electrodes. The front honeycomb electrode plate adsorbs large particulate pollutants, while the rear needle electrodes ionize the air and form a corona zone, causing small particles to become charged and captured by the metal mesh electrodes. This significantly improves the removal efficiency for particles of different sizes and is suitable for environments with high concentrations of pollutants. The corrugated filter uses a pleated corrugated structure to increase the air-facing area, ensuring full contact between the air and the filter and improving the particulate matter interception efficiency. By utilizing the photocatalytic effect of the nano-coating of the electrostatic filter combined with the ultraviolet lamp group, residual particulate matter is adsorbed a second time and organic matter and bacteria are decomposed, achieving deep purification.

[0016] This air conditioning unit adopts an axial flow fan and an oblique nozzle structure. The electrostatic filter can be quickly cleaned of accumulated dust by airflow after power failure, realizing regular cleaning of the electrostatic filter and blowing the adsorbed particles into the dust collection box. This avoids manual cleaning, extends the service life of the filter, and solves the problem of efficiency reduction caused by dust accumulation in traditional electrostatic adsorption components.

[0029] Example:

[0030] Reference Figures 1-7 An air conditioning unit that combines electrostatic adsorption and deep purification through a filter includes a unit housing 1. Two sets of fixing grooves 2 are fixedly connected inside the unit housing 1. An insulating partition 3 is fixedly connected between the two sets of fixing grooves 2. A honeycomb electrode plate 201 is provided in the fixing groove 2 on the left side. A support rod 202 is fixedly connected in the fixing groove 2 on the right side. Several needle-shaped electrodes 203 are fixedly connected to the end of the support rod 202. A metal mesh electrode 204 is provided on the side of the needle-shaped electrode 203 away from the support rod 202.

[0031] Inside the unit housing 1, a support groove 4 is fixedly connected. A HEPA filter 401 is provided on one side of the support groove 4, and an activated carbon adsorption layer 402 is provided on one side of the HEPA filter 401. Electrode plates 403 are fixedly connected to both sides of the inner wall of the support groove 4, and an electrostatic filter 404 is snapped into the electrode plate 403.

[0032] A corrugated filter 5 is provided on one side of the outer wall of the support groove 4. The corrugated filter 5 adopts a pleated corrugated structure. A guide plate 6 is inclinedly provided between the corrugated filter 5 and the fixed groove 2. A purging component is provided on the side of the support groove 4 away from the corrugated filter 5.

[0033] The purging assembly includes a support vertical plate 7 located inside the unit housing 1. An axial flow fan 701 is installed on the support vertical plate 7. The output end of the axial flow fan 701 is connected to a purging duct 702. The purging duct 702 is connected to the inner wall of the unit housing 1 through two Y-shaped support frames 703.

[0034] The end of the purge duct 702 away from the axial flow fan 701 extends above the electrostatic filter screen 404 and is fixedly connected to the flow duct 704. The flow duct 704 communicates with the interior of the purge duct 702. Several oblique spray holes are opened on the outer wall of the flow duct 704. A solenoid valve 705 is provided at the end of the purge duct 702 near the axial flow fan 701.

[0035] Ultraviolet lamps 8 are provided on both sides of the outer wall of the electrostatic layer filter 404, and the outer wall of the electrostatic layer filter 404 is coated with a nano-coating.

[0036] The outer walls of the ultraviolet lamp assembly 8, the fixing groove 2, and the electrostatic filter 404 are all provided with power-on terminals 9, and the output terminals of the power-on terminals 9 are connected to the external power supply terminals of the unit housing 1.

[0037] The inner wall of the unit casing 1 is provided with a discharge port, and a dust collection box 10 is provided inside the discharge port. The dust collection box 10 is located below the electrostatic filter 404 and has a snap-fit ​​opening on its outer wall.

[0038] In this embodiment, when the air conditioning unit is running, the ultraviolet lamp group 8, the fixing groove 2, and the electrostatic filter 404 are energized sequentially using the power-on terminal 9. Air then enters the interior of the unit casing 1, first passing through the honeycomb electrode plate 201. Large particulate pollutants mixed in the air are adsorbed onto the surface of the honeycomb electrode plate 201 under the influence of the electric field. Small particulate pollutants then pass through and enter the needle electrode 203. The insulating partition 3 in the middle prevents interference from the electric field. When the needle electrode 203 is energized, an electromagnetic field is generated nearby, ionizing the air and producing a large number of electrons and positive ions. Under the influence of the electric field, the electrons move towards the metal mesh electrode 204, colliding with airborne particles during their movement, causing the particles to become negatively charged. The positive ions are then adsorbed onto the needle electrode 203, forming a corona region. Subsequently, the negatively charged particles move towards the metal mesh electrode 204 under the influence of the electric field and are adsorbed within the mesh of the metal mesh electrode 204, thus achieving the dust removal effect.

[0039] Furthermore, when the air pretreated by the needle electrode 203 and the metal mesh electrode 204 passes through the guide plate 6, the air moves into the corrugated filter 5 under the guidance of the guide plate 6. Since the corrugated filter 5 adopts a pleated corrugated structure, its pleated corrugated structure increases the windward area of ​​the corrugated filter 5, allowing the air to come into more full contact with the corrugated filter 5, capturing more dust particulate pollutants and improving filtration efficiency. Subsequently, the HEPA filter 401 intercepts and filters the fine particles remaining in the air, and the activated carbon adsorption layer 402 adsorbs the gaseous pollutants mixed in the air, further purifying them.

[0040] Furthermore, as air passes through the electrostatic filter 404, the electrode plate 403 applies a voltage to the electrostatic filter 404, causing the electrostatic filter 404 to further adsorb residual particulate matter in the air. Simultaneously, the ultraviolet lamp 8 is activated, irradiating the nano-coating on the surface of the electrostatic filter 404, thereby decomposing the organic matter and bacteria adsorbed on the electrostatic filter 404. After adsorption is complete, the electrostatic filter 404 will accumulate a large amount of residual particulate matter. At this point, the connection to the energized terminal 9 of the electrostatic filter 404 is disconnected, and then the support... An axial flow fan 701 is mounted on one side of the vertical plate 7, and a solenoid valve 705 is opened. When the axial flow fan 701 is running, the airflow flows through the purge duct 702 to the flow duct 704, and then blows downwards through the angled nozzles on the flow duct 704 towards the electrostatic filter screen 404. This causes the airflow to blow from top to bottom onto the electrostatic filter screen 404, thereby blowing the dust particles adhering to the electrostatic filter screen 404 into the dust collection box 10 below. Then, the dust collection box 10 is pulled out from the discharge port, achieving the effect of centralized and unified collection and cleaning of particulate matter. At this time, the ultraviolet lamp group 8 continuously irradiates and inhibits bacterial growth.
