[0002] With the improvement of living quality, people's demand for indoor odor purification is increasing. At present, the commonly used odor removal technology is mainly adsorption, which has problems such as unsatisfactory adsorption effect and easy saturation of adsorption materials.

[0003] With continuous development, a dual-medium plasma discharge device using a plasma discharge device to remove odors has emerged.

In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0048] In some embodiments of the present application, an air conditioner is provided. Referring to Figure 1 as shown, the air conditioner includes:

[0049] A housing 100, on which an air return part 110 is formed. The air return part 110 is an air inlet formed on the housing 100 to enable external air flow to enter the interior of the housing 100.

[0050] An air outlet part 120 is formed on the housing 100. The air outlet part 120 is an air outlet formed on the housing 100 and is used to discharge the heat-exchanged air flow.

[0051] The housing 100 constitutes the outer shell of the indoor unit of the air conditioner, and a heat exchange air duct is formed inside the housing 100. The heat exchange air duct is formed between the air return part 110 and the air outlet part 120 and is used for the air flow to circulate. The air flow enters from the air return part 110, flows through the heat exchange air duct, and then flows out from the air outlet part 120. The air flow flowing into the heat exchange air duct exchanges heat inside it.

[0052] An evaporator 300 is arranged in the heat exchange air duct and is used to exchange heat with the air flow flowing through the heat exchange air duct. By exchanging heat between the evaporator 300 and the air flow in the heat exchange air duct, the heating or cooling of the air flow can be realized, so that the air flow blown out from the air return part 120 is the heated or cooled air flow, thereby realizing the refrigeration or heating effect of the air conditioner accordingly.

[0053] A blowing device 200 is arranged in the heat exchange air duct and is used to drive the air flow to circulate in the heat exchange air duct and control the flow rate of the air flow in the heat exchange air duct.

[0054] Through the blowing device 200, the air flow can be sucked from the air return part into the heat exchange air duct to exchange heat with the evaporator and then the air flow is sent out from the air outlet part 120. The blowing device 200 provides the power for the circular movement of the air flow.

[0055] The refrigeration cycle circuit is formed by connecting a compressor, a main expansion valve, a condenser, and an evaporator 300 through refrigerant pipelines.

[0056] The refrigeration cycle of the air conditioner is performed by using a compressor, a condenser, a main expansion valve, and an evaporator 300. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat the indoor space.

[0057] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0058] The main expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state formed by condensation in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the main expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by using the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0059] The outdoor unit of the air conditioner refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger. The indoor unit of the air conditioner includes the indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0060] The indoor heat exchanger and the outdoor heat exchanger are used as condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner serves as a heater in the heating mode. When the indoor heat exchanger is used as an evaporator, the air conditioner serves as a cooler in the cooling mode.

[0061] In some embodiments, an air purification device is provided in the air flow path of the air conditioner, which is arranged at the return air portion 110 and is used to purify the air discharged into the room.

[0062] In some embodiments, the air purification device is arranged at the air outlet portion 120, which purifies the air flow when the air flows out into the room.

[0063] In some embodiments, the air purification device is arranged inside the heat exchange air duct to purify the air flow passing through the heat exchange air duct, which can also ensure that the air entering the room is clean and purified air.

[0064] In some embodiments, referring to Figure 2 As shown, the air purification device is composed of a grounding portion 400, a power supply portion 500, and an emission electrode assembly horizontally connected between the grounding portion 400 and the power supply portion 500.

[0065] The grounding portion 400 is connected to the ground and is used to achieve the grounding function.

[0066] The power supply unit 500 can be used to supply power to the emission electrode assembly electrically connected thereto.

[0067] The emission electrode assembly is connected between the grounding unit 400 and the power supply unit 500 and includes

[0068] a plurality of electrode components 600, and the plurality of electrode components 600 are arranged side by side.

[0069] In some embodiments, the plurality of electrode components 600 arranged side by side all extend horizontally along the direction from the power supply unit 500 to the grounding unit 400.

[0070] In some embodiments, the plurality of electrode components 600 are parallel to each other and the structures of the plurality of electrode components 600 are exactly the same.

[0071] Referring to Figure 3 as shown, during connection, some of the plurality of electrode components 600 are electrically connected to the power supply unit 500, and the other ends are mechanically connected to the grounding unit 400, and both ends thereof are respectively supported and fixed by the power supply unit 500 and the grounding unit 400.

[0072] Another part of the electrode components 600 is connected to the grounding unit 400 to achieve grounding, and the other ends are connected and mechanically assembled to the power supply unit 500, and both ends thereof are respectively supported and fixed by the power supply unit 500 and the grounding unit 400.

[0073] The plurality of electrode components 600 electrically connected to the power supply unit 500 and the plurality of electrode components 600 electrically connected to the grounding unit 400 are alternately arranged in sequence.

[0074] After the connection is completed, one of the adjacent electrode components 600 is electrically connected to the power supply unit 500 at one end and assembled to the grounding unit 400 at the other end.

[0075] One end of another electrode component 600 is connected to the grounding unit 400 for grounding, and the other end is assembled to the power supply unit 500.

[0076] The electrode components 600 electrically connected to the power supply unit 500 form high-voltage electrode components 600, and the electrode components 600 connected to the grounding unit 400 form grounding electrode components 600.

[0077] The high-voltage electrode components 600 are connected to the power supply unit 500, the grounding electrode components 600 are connected to the grounding unit 400, and the voltages of the high-voltage electrode components 600 and the grounding electrode components 600 are different. Therefore, there can be a potential difference between the adjacent high-voltage electrode components 600 and the grounding electrode components 600, and a high-frequency high-voltage electric field is formed. The molecular chains of odor molecules can be broken by the high-frequency high-voltage electric field to form small molecule fragments.

[0078] In some embodiments, a discharge gap 700 through which gas molecules flow is formed between two adjacent electrode components 600. The distance of the discharge gap 700 left between the two electrode components 600 is 2 to 5 mm.

[0079] When setting, the number of electrode components 600 can be set according to actual usage requirements, and it is okay to set 4, 6, 8, etc. for the electrode components 600.

[0080] When the indoor polluted air passes through the discharge gap 700 formed between the two electrode components 600, the molecular chains of harmful gases are directly broken under the action of a high-frequency high-voltage electric field.

[0081] Meanwhile, plasma is generated during the ionization of air by the electrode components 600. The plasma will further react with the broken small molecules to generate harmless substances such as carbon dioxide and water, achieving the elimination of odor molecules. At the same time, bacteria and viruses will also have their cell walls and RNA directly damaged by the high-voltage electric field when passing through the discharge gap 700 and thus be killed, so as to achieve a good odor removal and purification effect.

[0082] The air flow entering the casing 100 of the air conditioner from the return air part will flow through the air purification device arranged at the return air part, the heat exchange air duct or the return air part 120. When the odor molecules in the air flow pass through the discharge gap 700, they will be broken and react with the plasma, and be eliminated, achieving a good odor removal effect for the air conditioner.

[0083] In terms of structural arrangement, the grounding part 400 and the power supply part 500 are respectively arranged at both ends of the emitting electrode assembly. When connecting, one end of some electrode components 600 is electrically connected to the power supply part 500, and one end is assembled to the grounding part 400. One end of some electrode components 600 is connected to the grounding part 400 for grounding, and one end is assembled to the power supply part 500. This not only realizes the support and fixation of the electrode components 600, but also realizes the integrated connection and assembly of multiple electrode components 600 with the grounding part 400 and the power supply part 500. The whole connection structure is not only compact but also simpler, making it more convenient to be assembled to positions such as the return air part or the return air part 120 of the air conditioner during use, facilitating assembly and installation.

[0084] The electrode component 600 has a wiring end for electrical connection. When connecting, the wiring ends of some electrode components 600 are connected to the power supply part 500, and the wiring ends of some electrode components 600 are connected to the grounding part 400.

[0085] In some embodiments of the present application, referring to Figure 5 、 Figures 13 - 16 as shown, the electrode component 600 includes: an insulating dielectric shell 610 and an internal conductive component.

[0086] In some embodiments, the insulating dielectric shell 610 is an insulating dielectric shell with a certain length. In some embodiments, the insulating dielectric shell 610 is made of quartz glass tube with good insulation.

[0087] In some embodiments, the outer diameter of the insulating dielectric shell 610 is between 10 and 20 mm.

[0088] In some embodiments, the insulating dielectric shell 610 is made of materials such as ceramics, PTFE or nylon.

[0089] In some embodiments, the insulating dielectric shell 610 has a pipe orifice 616, through which it is convenient to assemble the conductive component into it.

[0090] In some embodiments, the conductive component includes: a conductive member 620. The conductive member 620 is inserted into the insulating dielectric shell 610 from the pipe orifice 616 along the axial direction of the insulating dielectric shell 610. When inserted, it is inserted to the position at one end far from the pipe orifice 616.

[0091] In some embodiments, the conductive member 620 is hollow inside, and a notch portion 621 extending along its axial direction is formed on the side wall of the conductive member 620.

[0092] The notch portion 621 is configured to radially deform the conductive member 620 assembled into the insulating dielectric shell 610 to fit snugly against the inner wall of the insulating dielectric shell 610.

[0093] The dimensional accuracy of the insulating dielectric shell 610 is poor during the high-temperature manufacturing process. Therefore, when the inner size of the insulating dielectric shell 610 is too small, if the dimensional accuracy of the conductive member 620 remains unchanged, it is difficult for the conductive member 620 to be inserted into the glass tube.

[0094] In addition, due to the strict requirements for the parallelism between the electrodes of the low-temperature plasma electrode pair, non-parallel electrodes will cause uneven discharge between the electrodes. When the inner wall size of the insulating dielectric shell 610 is too large, the conductive member 620 will shake inside the insulating dielectric shell 610, resulting in the conductive member 620 not being able to fit completely against the inner wall of the insulating dielectric shell 610, causing the electrodes to be non-parallel.

[0095] The notch portion 621 axially formed along the conductive member 620 can make the notch portion 621 communicate with the internal space of the conductive member 620, so that the conductive member 620 can deform through the notch portion 621.

[0096] During processing, the notch portion 621 is formed by wire cutting technology to extend along the axial direction of the conductive member 620, so that the conductive member 620 will elastically deform in the radial direction under the action of internal stress, making the diameter of the conductive member 620 larger. At this time, the conductive member 620 with a notch has a certain elastic variable in the diameter direction.

[0097] When the actual inner diameter of the insulating dielectric shell 610 is larger than the reference inner diameter due to processing deviation, the conductive member 620 will expand radially, thereby ensuring that the outer wall of the conductive member 620 fits the inner diameter of the insulating dielectric shell 610 and keeps in contact with the inner wall of the insulating dielectric shell 610.

[0098] When the actual inner diameter of the insulating dielectric shell 610 is smaller than the reference inner diameter due to processing deviation, the conductive member 620 inserted inside it will be compressed and deformed in the radial direction due to the extrusion force from the inner wall of the insulating dielectric shell 610, with its size becoming smaller. Similarly, it ensures close contact with the inner wall of the insulating dielectric shell 610, thereby ensuring the parallelism and installation accuracy of the plasma electrode.

[0099] In some embodiments, the conductive member 620 is a metal part with conductivity, which can be used to ensure normal conduction of the electrode.

[0100] The conductive member 620 can be made of iron, copper, stainless steel, etc. It not only ensures conductivity but also has a certain hardness, so that it can be quickly and conveniently inserted into the insulating dielectric shell 610 during assembly to achieve its quick and convenient installation.

[0101] In some embodiments, the outer diameter of the conductive member 620 is less than 5% - 8% of the inner diameter of the insulating dielectric shell 610, and the wall thickness of the tube is less than 0.7 mm, so that the deformation amount in the diameter direction after processing can meet the processing error requirements of the insulating dielectric shell 610.

[0102] In some embodiments, the outer diameter of the conductive member 620 is less than 5% of the inner diameter of the insulating dielectric shell 610.

[0103] In some embodiments, the outer diameter of the conductive member 620 is less than 6% of the inner diameter of the insulating dielectric shell 610.

[0104] In some embodiments, the outer diameter of the conductive member 620 is less than 8% of the inner diameter of the insulating dielectric shell 610.

[0105] In some embodiments, the wall thickness of the conductive member 620 is 0.1 mm.

[0106] In some embodiments, the wall thickness of the conductive member 620 is 0.3 mm.

[0107] In some embodiments, the wall thickness of the conductive member 620 is 0.5 mm.

[0108] In some embodiments, the wall thickness of the conductive member 620 is 0.6 mm.

[0109] When in use, the conductive member 620 should neither expand too much so that it cannot be effectively inserted into the insulating dielectric housing 610, nor expand too little, causing the conductive member 620 to shake within the insulating dielectric housing 610. The diameter of the conductive member 620 is set such that its outer diameter is less than 5% - 8% of the inner diameter of the insulating dielectric housing 610, ensuring that the conductive member 620 deforms within a suitable size range.

[0110] In some embodiments, the conductive assembly includes: a conductive connecting member 630 disposed within the insulating dielectric housing 610, one end of which is connected to the conductive member 620 and the other end extends out of the insulating dielectric housing 610.

[0111] The conductive connecting member 630 is mainly used to achieve electrical connection for wiring, and it can be used to connect to the power supply unit 500 or the grounding unit 400.

[0112] In some embodiments, the conductive connecting member 630 is a conductive post, which is arranged side by side with the conductive member 620 within the insulating dielectric housing 610 and extends outwards from the pipe orifice 616.

[0113] External threads 631 are provided on the extending section of the conductive connecting member 630 to facilitate later wiring operations.

[0114] In some embodiments of the present application, Figure 15 As shown, the conductive member 620 has a first end 623 and a second end 624 at its two ends, and the notch portion 621 extends from the first end 623 to the second end 624 along the axial direction of the conductive member 620.

[0115] The notch portion 621 is a long strip notch opened along the entire length direction of the conductive member 620.

[0116] The long strip opening is used to ensure that the conductive member 620 can deform radially at various positions along the entire length direction, ensuring that all positions of the conductive member 620 are in contact with the inner wall of the insulating dielectric housing 610, and ensuring the parallelism and installation accuracy of the electrode component 600.

[0117] In some embodiments, the conductive member 620 is a conductive sleeve, and a first through hole and a second through hole are formed through both ends thereof, and the notch portion 621 extends from the first through hole to the second through hole.

[0118] In some embodiments, both ends of the conductive member 620 are not through, and hollowed portions are formed at positions corresponding to the notch portion 621 on the end faces of both ends of the conductive member 620 to ensure that the conductive member 620 can deform radially normally.

[0119] In some embodiments of the present application, the conductive member 620 has a first end 623 and a second end 624 formed at both ends, and the second end 624 is disposed opposite to the first end 623.

[0120] In some embodiments, the notch portion 621 includes a first deformation opening 6211, which extends from the first end 623 of the conductive member 620 along the axial direction of the conductive member 620 towards the second end 624.

[0121] In some embodiments, with reference to Figure 19 As shown, the notch portion 621 includes a second deformation opening 6212. The second deformation opening 6212 and the first deformation opening 6211 are arranged staggeredly in the circumferential direction of the conductive member 620. The second deformation opening 6212 extends from the second end 624 of the conductive member 620 along the axial direction of the conductive member 620 towards the first end 623. One end of the second deformation opening 6212 far from the second end 624 is flush with one end of the first deformation opening 6211 far from the first end 623.

[0122] The notch portion 621 arranged along the axial direction of the conductive member 620 is formed by the staggeredly arranged first deformation opening 6211 and second deformation opening 6212.

[0123] The first deformation opening 6211 deforms the conductive member 620 on the segment of the conductive member 620 corresponding to the first deformation opening. The second deformation opening can deform the conductive member 620 on the segment of the conductive member 620 corresponding to the second deformation opening 6212. Through the cooperation of the two, it can also ensure that the entire conductive member 620 deforms in the radial direction to fit and keep in contact with the inner wall of the insulating dielectric shell 610.

[0124] In some embodiments of the present application, the conductive member 620 includes:

[0125] A sleeve body, with a first through portion 625 and a second through portion 626 formed at both ends. The first through portion 625 and the second through portion 626 are communicated with the inner space of the sleeve body. The first through portion 625 is closer to the conductive connecting member 630 than the second through portion 626.

[0126] The first through portion 625 is a first through opening, and the second through portion 626 is a second through opening. The two are communicated with the inner space of the sleeve body to form a conductive kit 5323.

[0127] A connecting portion 627 is formed around the first through portion 625. The connecting portion 627 extends along the axial direction of the insulating dielectric shell 610 to the conductive connecting member 630 and is connected to the conductive connecting member 630.

[0128] The first through portion 625 is close to the conductive connecting member 630. By forming the connecting portion 627 around the first through portion 625, the connection with the conductive connecting member 630 can be achieved at a relatively short distance.

[0129] It is connected through the connecting part 627 and the conductive connecting piece 630 to ensure the continuity of the electrical transmission path and guarantee the transmission of electricity.

[0130] In some embodiments of the present application, a plurality of the connecting parts 627 are provided and arranged circumferentially along the first through part 625. The connection with the conductive connecting piece 630 through the plurality of connecting parts 627 ensures the firmness of the connection.

[0131] During molding, a part can be cut off from the middle at one end of the conductive part 620 by wire cutting, so that one connecting part 627 is left on each side, and the two connecting parts 627 are symmetrically distributed on both sides of the notch part 621.

[0132] In some embodiments, the connecting part 627 includes:

[0133] An inclined connecting arm 6271, which is inclined from the conductive part 620 towards the conductive connecting piece 630, and is used to realize the transition of the connection from the conductive part 620 to the conductive connecting piece 630.

[0134] A straight connecting arm 6272, which is connected to the inclined connecting arm 6271, fits against the outer wall of the conductive connecting piece 630 and is fixedly welded to it. The straight connecting arm 6272 can be fixedly welded to the outer side wall of the conductive connecting piece 630 to realize the connection with the conductive connecting piece 630.

[0135] During connection, the conductive connecting piece 630 is inserted into the middle position of the plurality of connecting parts 627, and the plurality of connecting parts 627 are welded to the conductive connecting piece 630 simultaneously by spot welding.

[0136] In some embodiments of the present application, a raised positioning protrusion part 613 is formed on the inner wall of the insulating dielectric shell 610, and is used to be inserted into the notch part 621 to guide and position the installation of the conductive part 620.

[0137] After the notch part 621 is processed on the conductive part 620, there is no conductive substance at the notch part 621, so plasma discharge cannot be carried out at the notch part 621. When arranging multiple plasma electrode components 600, the notch part 621 cannot be facing another plasma electrode component 600, so the notch part 621 needs to be positioned.

[0138] Through the positioning protrusion part 613 designed at a specific position inside the insulating dielectric shell 610, when installing the conductive part 620, the notch part 621 is aligned with the positioning protrusion part 613, and the conductive part 620 is inserted into the insulating dielectric part. The notch part 621 is guided by the positioning protrusion part 613, so that all the notch parts 621 can be inserted into the insulating dielectric shell 610 along the same direction, and the notch parts 621 of multiple electrode components 600 all face one direction.

[0139] In some embodiments of the present application, the insulating dielectric housing 610 has a first connection end 614, and a limiting convex portion 612 for positioning its assembly position to the power supply portion 500 or the grounding portion 400 is provided on the insulating dielectric housing 610 near the first connection end 614.

[0140] During assembly, the insulating dielectric housing 610 is inserted into the power supply portion 500 or the grounding portion 400, and its insertion position can be limited by the limiting convex portion 612, so that it can be quickly assembled in place.

[0141] The insulating dielectric housing 610 includes a second connection end 615, and a threaded connection portion 611 for connecting and cooperating with the grounding portion 400 or the power supply portion 500 is formed at the second connection end 615.

[0142] The threaded connection portion 611 is a threaded connection hole for screwing into the power supply portion 500 or the grounding portion 400 to achieve fixation.

[0143] In some embodiments of the present application, as shown in Figure 14 it includes a fixed sealing assembly, including:

[0144] A blocking member 640 is assembled in the insulating dielectric housing 610 and is located at a position between the second connection end 615 and the conductive member 620.

[0145] The blocking member 640 is a plug, which mainly plays a sealing role, and the plug has a certain length to increase the creepage distance of the electrode component 600 during use and improve safety. The pipe wall of the insulating dielectric housing 610 and the plug are connected by high-temperature welding. The pipe wall thickness should be between 1 and 1.5 mm.

[0146] During assembly, the conductive member 620 is mainly inserted into the insulating dielectric housing 610 from the pipe orifice 616 until the conductive member 620 contacts the bottom plug.

[0147] A seal 650 is inserted into the insulating dielectric housing 610 and is sleeved at the connection position of the conductive member 620 and the conductive connection member 630. The seal 650 is a sealing rubber plug.

[0148] After the conductive member 620 is inserted to the bottom of the insulating dielectric member, the seal 650 is pushed into the insulating dielectric housing 610 by a ring-shaped tooling until the welding position of the conductive member 620 and the conductive connection member 630. Its main function is to prevent the sealant in the subsequent process from flowing into the inside of the conductive member 620.

[0149] The sealant is filled in the insulating dielectric housing 610 and is in the area between the seal 650 and the first connection end 614.

[0150] The sealing filler is an epoxy resin sealant. The epoxy resin sealant is poured into the remaining space of the insulating medium shell 610 and leveled with the pipe orifice 616. After the curing is completed, the assembly of the electrode component 600 is completed.

[0151] In some embodiments of the present application, the power supply unit 500 includes an insulating power supply shell 510, a high-voltage power supply unit 520 and an electrical connection component 530 assembled in the insulating power supply shell 510.

[0152] In some embodiments, referring to Figures 6 - 8 As shown, an assembly space 511 is formed inside the insulating power supply shell 510.

[0153] The insulating power supply shell 510 is injection-molded from insulating materials such as plastics like PP and ABS.

Through the first flange portion 512 and the first mounting hole 513, the assembly connection between the plasma generating device and the air conditioner can be realized.

[0155] During connection, the insulating power supply shell 510 can be partially locked and fixed to the air conditioner by passing a locking screw through the first mounting hole 513.

[0156] In some embodiments of the present application, a first insertion hole 514 is formed on the insulating power supply shell 510. The first insertion hole 514 is used to insert one end of the high-voltage electrode component 600 provided with a limiting protrusion portion 612, so that the high-voltage electrode component 600 is inserted above it and its end is supported.

[0157] A first threaded connection hole 515 is formed on the insulating power supply shell 510. The first threaded connection hole 515 is used to cooperate with the threaded connection portion 611 on the grounding electrode component 600. The grounding electrode component 600 is screwed into the first threaded connection hole 515 through the threaded connection portion 611 to realize the connection and fixation with the insulating power supply shell 510, and the support for one end of it is realized through the insulating power supply shell 510.

[0173] The screwing arm is continuously screwed onto the conductive connecting member 630 and applies a force to the first connecting member 531, squeezing the first connecting member 531 toward the insulating dielectric housing 610 side, and finally pressing the first connecting member 531 tightly against the end face of the insulating dielectric housing 610 to firmly fix the first connecting member 531.

[0174] The second connecting member 532 abuts and presses tightly on the first connecting member 531 and is locked and fixed to the conductive connecting member 630. The first connecting member 531 is connected to the high-voltage package 521, and the electricity transmitted from the high-voltage package 521 is transmitted to the first connecting member 531.
