[0001] The utility model relates to the technical field of air-conditioning units, and specifically discloses a sterilizing and purifying rooftop air-conditioning unit. Background Art

[0002] As the mainstream air-conditioning equipment for large commercial buildings, rooftop air-conditioning units have been widely used in places with strict air quality requirements such as hospitals, laboratories, and electronic factories.

[0003] When dealing with complex air pollutants, traditional rooftop air-conditioning units have obvious deficiencies in air purification:

[0004] (1) When sterilizing air, traditional rooftop air-conditioning units usually use ultraviolet lamps or electrostatic dust removal devices. Since ultraviolet sterilization requires a continuous irradiation time of 0.5 - 2 s, and the air flow velocity of the air conditioner usually reaches 2 - 3 m / s, the actual sterilization effect is not good. When using an electrostatic dust removal device for sterilization, ozone pollution will be generated;

[0005] (2) When filtering air, as the first line of defense against large particle pollutants, the dust-proof net will accumulate a large amount of dust and other impurities after long-term use. However, the existing cleaning methods mostly rely on manual operation, which not only consumes a large amount of manpower and time costs, but when the dust-proof net needs to be replaced, the traditional structural design makes the disassembly process extremely cumbersome, and it often takes a long time for professional technicians to complete with the help of special tools, which inevitably leads to the air-conditioning system being shut down for a long time. Content of the Utility Model

[0006] The utility model provides a sterilizing and purifying rooftop air-conditioning unit, which effectively improves the air purification and sterilization effect, has an automatic cleaning function for the dust-proof net, and is convenient for quickly disassembling and replacing the dust-proof net and HEPA filter, reducing the downtime.

[0007] The utility model is realized as follows. The sterilizing and purifying rooftop air-conditioning unit includes an air-conditioning chassis and an air outlet provided at the right end of the air-conditioning chassis. Inside the air-conditioning chassis, a first fan, an ionization sterilization area, and a pull-out HEPA filter are sequentially arranged from left to right; a filtering mechanism is provided on the left side of the air-conditioning chassis. The filtering mechanism includes a moving frame in the shape of a "return" character. A placement groove is opened at the right end inside the moving frame, and a dust-proof net is placed inside the placement groove. A screw rod is rotatably connected to the inner wall of the moving frame, a slider is threadedly connected to the outer side wall of the screw rod, a dust suction cover is fixedly installed on the side of the slider close to the dust-proof net, and a brush and a brush plate contacting the dust-proof net are detachably connected to the inner wall of the dust suction cover by bolts.

[0008] As a preferred embodiment of the sterilization and purification rooftop air conditioning unit of this utility model, the bipolar plates in the ionization sterilization zone are arranged in an alternating array to form a honeycomb-shaped airflow channel.

[0009] As a preferred embodiment of the sterilization and purification rooftop air conditioning unit of this utility model, the top of the air conditioning unit is provided with a through hole, and the bottom surface of the air conditioning unit is provided with a slot opposite to the through hole. Both the inner wall of the through hole and the inner wall of the slot are fitted with sealing gaskets. The bottom of the HEPA filter is engaged in the slot and the top extends into the interior of the through hole.

[0010] As a preferred embodiment of the sterilization and purification rooftop air conditioning unit of this utility model, a sealing groove is provided on the left side wall of the air conditioning unit, which is opposite to the placement groove. Sealing gaskets are installed inside the sealing groove and on the inner side wall of the placement groove.

The left side wall of the air conditioning unit is provided with limiting grooves that are slidably connected to the two limiting rods respectively. Fixing blocks are fixedly installed at both ends of the air conditioning unit and at both ends of the movable frame. An electric push rod for pushing the movable frame to move is installed between two fixing blocks located on the same side.

[0013] As a preferred embodiment of the sterilization and purification rooftop air conditioning unit of this utility model, a vacuum cleaner is fixedly installed on the outer wall of the movable frame, and the input end of the vacuum cleaner is connected to the outer wall of the vacuum hood by a corrugated pipe.

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

[0015] 1. Large particulate pollutants (such as dust and willow catkins) are intercepted by the dustproof net, and the HEPA filter removes PM2.5 and microorganisms to ensure air cleanliness.

Specific embodiments

[0024] The following will further illustrate the present invention in conjunction with the drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0025] Please refer to Figure 1-4 , the sterilizing and purifying rooftop air conditioner unit includes an air conditioner chassis 1 and an air outlet 101 provided at the right end of the air conditioner chassis 1. Inside the air conditioner chassis 1, a first fan 2, an ionization sterilization area 3, and a pull-out HEPA filter 4 are sequentially arranged from left to right; a filtering mechanism is provided on the left side of the air conditioner chassis 1. The filtering mechanism includes a "return" - shaped moving frame 5. A placement groove 501 is opened at the right end inside the moving frame 5. A dust-proof net 6 is placed inside the placement groove 501. A screw rod7 is rotatably connected to the inner wall of the moving frame 5. A slider 701 is threadedly connected to the outer side wall of the screw rod 7. A dust suction hood 8 is fixedly installed on the side of the slider 701 close to the dust-proof net 6. The inner wall of the dust suction hood 8 is detachably connected by bolts with bristles and a brush plate 801 that contacts the dust-proof net 6.

[0026] In this embodiment: the first fan 2 is started, the dust net 6 can intercept large particulate pollutants (such as dust and willow catkins), and then the air enters the ionization sterilization zone 3. Through the high-voltage bipolar plate array, ion clusters are generated to kill bacteria or viruses in the airflow. Then the sterilized air passes through the pull-out HEPA filter 4, which can remove PM2.5 and residual microorganisms, thus purifying and sterilizing the air.

[0027] The motor 702 is started, driving the screw 7 to rotate and causing the slider 701 and the dust cover 8 to move along the surface of the dustproof net 6. At this time, the brush plate 801 scrapes the dustproof net 6 to loosen the attached dust, and the vacuum cleaner 9 collects the cleaned dust, automatically cleaning the dustproof net 6. The two electric push rods 504 are activated, so that the moving frame 5 abuts against the outer wall of the air conditioner housing 1. At this time, one side of the dustproof net 6 can be tightly attached to the outer wall of the air conditioner housing 1, so that the sealing groove 104 and the sealing gasket in the placement groove 501 cooperate with each other to tightly fit the outer wall of the dustproof net 6 frame, preventing airflow leakage and achieving the sealing installation of the dustproof net 6. When the dustproof net 6 is removed, the moving frame 5 slides away from the air conditioner housing 1 through the support wheel 502 and the limit rod 106, making it easy to clean or replace the dustproof net 6.

[0028] As a technical optimization of this utility model, the ionization sterilization zone 3 is formed by an alternating array of bipolar plates to create a honeycomb-shaped airflow channel.

[0029] In this embodiment, the high-voltage ionization region uses a bipolar plate driven by a 20kHz intermediate frequency power supply, which enables the high-voltage bipolar plate array to generate ion clusters to kill bacteria or viruses. The bipolar plates are made of stainless steel or titanium alloy, which are corrosion resistant and extend service life.

[0030] As a technical optimization of this utility model, the top of the air conditioner casing 1 is provided with a through hole 102, and the bottom surface of the air conditioner casing 1 is provided with a slot 103 opposite to the through hole 102. Both the inner wall of the through hole 102 and the inner wall of the slot 103 are equipped with sealing gaskets. The bottom of the HEPA filter 4 is engaged in the slot 103 and the top extends out from the through hole 102.

[0031] In this embodiment: the sealing gasket is made of rubber, and since the HEPA filter 4 is retractable, the sealing performance between the slot 103 and the through hole 102 and the HEPA filter 4 can be increased when the HEPA filter 4 is installed.

[0032] As a technical optimization of this utility model, a sealing groove 104 is provided on the left side wall of the air conditioner casing 1, which is opposite to the placement groove 501. A sealing gasket is installed inside the sealing groove 104 and on the inner side wall of the placement groove 501.

[0033] In this embodiment: the sealing gasket is also made of rubber, which can increase the sealing performance between the sealing groove 104 and the placement groove 501 and the dustproof net 6.

[0034] As a technical optimization of this utility model, a motor 702 is fixedly installed on the upper end surface of the movable frame 5, the output end of the motor 702 is coaxially fixedly connected to the screw 7, and the front and rear ends of the slider 701 are slidably connected to the inner wall of the movable frame 5.

[0035] In this embodiment: starting the motor 702 causes the screw 7 to rotate, which can drive the slider 701 to move. At the same time, the inner wall of the moving frame 5 can restrict the movement direction of the slider 701 and prevent the slider 701 from rotating axially.

[0036] As a technical optimization of this utility model, multiple support wheels 502 are installed at the bottom of the movable frame 5, and two vertically distributed limiting rods 106 are fixedly installed on the right side of the movable frame 5. The left side wall of the air conditioner housing 1 is provided with limiting grooves 105 that are slidably connected to the two limiting rods 106 respectively. Fixing blocks 503 are fixedly installed at both the front and rear ends of the air conditioner housing 1 and the front and rear ends of the movable frame 5. An electric push rod 504 for pushing the movable frame 5 to move is installed between the two fixing blocks 503 on the same side.

[0037] In this embodiment: by activating the electric actuator 504, the moving frame 5 can be moved. When the moving frame 5 moves, it can drive the limiting rod 106 to move along the limiting groove 105. The limiting groove 105 can restrict the moving direction of the limiting rod 106, so that the moving frame 5 can move stably.

[0038] As a technical optimization of this utility model, a vacuum cleaner 9 is fixedly installed on the outer wall of the movable frame 5, and the input end of the vacuum cleaner 9 is connected to the outer wall of the vacuum hood 8 by a corrugated pipe 802.

[0039] In this embodiment: when the vacuum cleaner 9 (industrial vacuum cleaner PT2230) is started, the dust inside the vacuum hood 8 can be collected in the vacuum cleaner 9 through the corrugated pipe 802.

[0040] The working principle and usage process of this utility model are as follows: The device is connected to an external power supply and a PLC controller. The air outlet 101 can be connected to the air conditioning duct inverter refrigeration system (not shown in the figure). In use, the dustproof net 6 is first placed in the placement slot 501. Then, two electric actuators 504 are started simultaneously (the PLC controller can control the simultaneous operation of the two electric actuators 504). At this time, multiple support wheels 502 support the moving frame 5 to move towards the air conditioning unit 1, so that the moving frame 5 abuts against the outer wall of the air conditioning unit 1. At this time, one side of the dustproof net 6 can be tightly attached to the outer wall of the air conditioning unit 1, so that the sealing groove 104 and the sealing gasket in the placement slot 501 cooperate closely and fit tightly against the outer wall of the dustproof net 6 frame, preventing airflow leakage and achieving a sealed installation of the dustproof net 6. When the dustproof net 6 is removed, the moving frame 5 slides away from the air conditioning unit 1 via the support wheels 502 and the limit rod 106, facilitating cleaning or replacement of the dustproof net 6.

[0041] When the first fan 2 is started, the outside air first passes through the dust filter 6, which can intercept large particulate pollutants (such as dust and willow catkins). Then the air enters the ionization sterilization zone 3, where it passes through a high-voltage (±5kV~±8kV) bipolar plate array to generate ion clusters to kill bacteria or viruses in the airflow. After sterilization, the air passes through the pull-out HEPA filter 4, which can remove PM2.5 and residual microorganisms, and finally is discharged from the air outlet 101.

[0042] When cleaning the dust filter 6, start the motor 702, drive the screw 7 to rotate and move the slider 701 and the dust cover 8 along the surface of the dust filter 6. At this time, the brush plate 801 scrapes the dust filter 6 to loosen the dust attached to it; at the same time, the vacuum cleaner 9 sucks the dust into the dust collection chamber of the vacuum cleaner 9 through the corrugated pipe 802 (not shown in the figure).
