TECHNICAL FIELD

[0002] The present application belongs to the technical field of air conditioners, and in particular relates to an air conditioner. BACKGROUND

[0003] At present, the indoor unit of an air conditioner has an indoor housing forming its appearance, and the indoor housing is provided with an air inlet and an air outlet. The air outlet is used for the heat exchange air in the air outlet duct to flow out, and the air outlet is usually provided with an electrically charged fine particle water generating device.

[0004] The electrically charged fine particle water generating device includes an electrode component. By performing high-voltage discharge on the moisture on the electrode component, the moisture is gradually split into water mist, and is decomposed into nanoscale water ions with high activity, which contain a large amount of electric charge and highly active hydroxyl radicals. The electrically charged fine particle water generating device can decompose and remove bacteria, microorganisms, formaldehyde, VOC, and other components in the air.

[0005] Whether the electrically charged fine particle water generating device can release water ions and how high the concentration of the water ions that can be released are largely determined by how much water can participate in ionization when the generator is working.

[0006] In the related art, a semiconductor refrigeration scheme is used to cool the discharge electrode, so that the front end of the discharge electrode maintains atomized condensed water. This scheme has a limited applicable air humidity range because it needs to condense and liquefy water in the air. Generally, it can effectively generate condensed water only in a humidity of 60% or more. The performance is greatly affected by the environmental humidity. Meanwhile, the semiconductor refrigeration components in the device need to be powered, which causes redundant power consumption. An electric control unit needs to be added, which increases the risk of failure. SUMMARY

[0007] Some embodiments of the present application propose an air conditioner. Water-absorbing material is incorporated into the solidified matrix of the charged microparticle water generating device, so that the electrode component can absorb moisture in the air under low humidity conditions, provide a relatively stable water source for ionization, and ensure stable release of ions.

[0008] Some embodiments of the present application propose an air conditioner, which comprises:

[0009] An indoor housing, which is provided with an air inlet and an air outlet;

[0010] A charged microparticle water generating device installed at the air outlet to generate ions, which comprises:

[0011] A voltage output component for outputting a first voltage;

[0012] An electrode component for receiving the first voltage output by the voltage output component and ionizing the absorbed moisture in the air. The electrode component further comprises:

[0013] A solidified matrix;

[0014] A plurality of conductive fibers dispersedly arranged in the solidified matrix, and the emission tips of the conductive fibers extend to the outside of the solidified matrix, so that one end of the electrode component forms an emission end with a bare multi-fiber structure;

[0015] Water-absorbing material incorporated into the solidified matrix to at least arrange on the surface of the solidified matrix to absorb moisture in the air.

[0016] The application discloses an air conditioner, comprising an electrically charged micro-particle water generating device arranged at an air outlet, the device comprising a voltage output component outputting a first voltage and an electrode component receiving the first voltage, the electrode component further comprising a solidified base, a plurality of electrically conductive fibers dispersedly arranged in the solidified base, and a water-absorbing material. The water-absorbing material is incorporated into the solidified base and arranged at least on the surface of the solidified base to absorb moisture in the air. The water-absorbing material is dispersed in the solidified base and on the outer surface of the solidified base. The water-absorbing material on the outer surface of the electrode component is in contact with the air, and can efficiently capture water molecules in the air by virtue of the high active sites, thereby achieving high moisture absorption. The water-absorbing material inside the electrode component plays a role in preserving moisture. Thus, the electrode component still has high moisture absorption under low humidity conditions, so that the electrode component has the ability to stably release ions in a low humidity environment. When the electrode component and the voltage output component are connected, the moisture absorbed by the water-absorbing material is ionized into water ions, such as hydroxyl radicals, by the high-voltage electric emission tip of the electrically conductive fiber, and the hydroxyl radicals are wrapped by water particles to form hydroxyl electrically charged micro-particle water, which has air purification effects of sterilization and odor removal.

[0075] In some embodiments, the front surface, the top surface, and part of the bottom surface are provided as one body. This facilitates stable connection between the back panel and the side panels, and forms a stable external structure of the air conditioner 100.

[0076] In some embodiments, the back panel and part of the bottom surface are provided as one body. This facilitates stable connection of other components, and forms a stable external structure of the air conditioner 100.

[0077] The indoor unit includes an indoor heat exchanger. The indoor heat exchanger is installed in the indoor housing 1. The indoor heat exchanger is used to exchange heat with the airflow entering the indoor housing 1.

[0078] The indoor unit includes an indoor fan. The indoor fan is installed in the indoor housing 1, and rotates to draw indoor air into the indoor housing 1, and the indoor air exchanges heat with the indoor heat exchanger and then flows out of the indoor housing 1.

[0079] The front panel, the rear panel, the bottom surface, the top surface, and the side panels enclose a heat exchange air duct.

[0080] In some embodiments, the indoor fan is provided as a cross-flow fan. The inner periphery of the rear panel is provided with a space for installing the indoor fan.

[0081] In some embodiments, the indoor heat exchanger is arranged around the indoor fan.

[0082] In some embodiments, the air conditioner 100 further includes a compressor, which can compress a gaseous refrigerant at a high temperature and high pressure and discharge the compressed gaseous refrigerant.

[0083] The compressor includes a suction port. The refrigerant flows into the compressor from the suction port to be compressed.

[0084] The compressor includes a discharge port. The refrigerant enters the compressor from the suction port, and after being compressed by the compressor, it is discharged from the discharge port.

[0085] In some embodiments, the air conditioner 100 further includes an indoor heat exchanger for heat exchange with indoor air.

The fourth port of the four-way valve is connected to the outdoor heat exchanger.

[0088] The air conditioner 100 further includes a throttling pressure reducing device, such as an electronic expansion valve. The electronic expansion valve is provided between the outdoor heat exchanger and the indoor heat exchanger. The electronic expansion valve is used for throttling. The electronic expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0089] The indoor heat exchanger and the outdoor heat exchanger are used as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner 100 is used as a heater in a heating mode.

[0093] Referring to FIG. 2, the indoor unit further comprises an electrically charged fine particle water generating device 5 installed at the air outlet 3 to generate ions having air purification effects of sterilization and odor removal, and the generated ions are blown into the indoor environment to improve the air purification effect.

[0094] In some embodiments, referring to FIG. 27, the electrically charged fine particle water generating device 5 comprises a voltage output component 51. The voltage output component 51 can be integrated into the main control circuit module of the air conditioner. The voltage output component 51 is used to output a stable first voltage to ensure the stability and ion quantity of the electrically charged fine particle water generating device 5 releasing ions.

[0095] As shown in FIG. 3, the electrically charged fine particle water generating device 5 comprises an electrode component 52. The electrode component 52 is used to absorb moisture in the air and release ions using the received first voltage.

[0096] In some embodiments, the electrically charged fine particle water generating device 5 is installed at the air outlet 3. At least the electrode component 52 is installed at the air outlet 3 so that the ions generated by the electrode component 52 can enter the indoor environment with the airflow of the air outlet 3.

[0097] In some embodiments, as shown in FIG. 5, the electrode component 52 comprises a solidified matrix 521.

[0098] In some embodiments, the solidified matrix 521 can be composed of a crosslinking agent and an initiator in a certain proportion.

[0099] In the above, the crosslinking agent is a substance that can bridge the connection between linear structure molecules during condensation, and make the groups in the molecules bond with each other to become a non-melting network.

[0100] The initiator is a substance capable of initiating the monomer to carry out the polymerization reaction. The unsaturated monomer polymerization active center has free radical type, anion type, cation type and coordination compound, etc. The free radical type is most commonly used in the adhesive industry. It shows unique chemical activity. Under the action of heat or light, covalent bond homolysis occurs to generate two free radicals, which can initiate polymerization.

[0101] In some embodiments, the crosslinking agent is first added to the mold to undergo a crosslinking reaction to form a crosslinked structure; then the initiator is added to initiate the monomer polymerization reaction by the initiator, so that the monomer in the crosslinked structure is polymerized, and finally a high molecular material with a crosslinked structure is obtained.

[0102] The electrode component 52 includes conductive fibers 522. The conductive fibers 522 can realize electrical conduction and form a local electric field at the end of the conductive fibers 522.

[0103] The conductive fibers 522 are arranged in a plurality of conductive fibers 522 dispersedly arranged in the cured matrix 521. The cured matrix 521 and the conductive fibers 522 constitute the main structure of the electrode component 52.

[0104] In some embodiments, the emission tip of the conductive fiber 522 extends to the outside of the cured matrix 521, so that one end of the electrode component 52 forms an emission end with a bare multi-fiber structure.

[0105] In the present embodiment, the conductive fibers 522 are molded into a rod-shaped structure by the cured matrix 521. In some embodiments, the main structure formed by the conductive fibers 522 and the cured matrix 521 can also be arranged as a cylindrical structure, a cubic column structure, and a flat sheet structure. It should be noted that the shape of the main structure is not limited herein, and the shape of the main structure can be connected to the first voltage and the emission end to generate an electric field.

[0106] In some embodiments, the electrode component 52 as a whole can be arranged as a solid structure. In some embodiments, the electrode component 52 as a whole can also be arranged as a cylindrical structure, a hollow structure, and a mesh structure, etc.

[0107] In some embodiments, the conductive fibers 522 are regularly arranged in the cured matrix 521 and form the main structure of the electrode component 52 with the cured matrix 521.

[0108] In some embodiments, the conductive fibers 522 are distributed in the interior and the outer surface of the cured matrix 521.

[0109] In some embodiments, the conductive fibers 522 are arranged as carbon fibers.

[0110] Carbon fiber is a fiber made of carbon atoms, which has good electrical conductivity like metal. It can quickly transfer electrons at low voltage. Moreover, carbon fiber has high strength and stiffness per unit mass or volume, and the diameter of carbon fiber bundle can be from several microns to tens of microns, which can reach one tenth or even one hundredth of the curvature radius of the pointed structure electrode.

[0111] Compared with the pointed structure electrode, carbon fiber can generate a stronger local electric field under the same power supply voltage, frequency and other conditions, and ionize to produce a higher concentration of air anions or water ions.

[0112] In this embodiment, the unidirectional carbon fiber is used as the conductive fiber 522. The selection of this carbon structure as the conductive framework can induce the increase of the single-direction electron migration activity of the electrode, thereby promoting the increase of the single-direction negative ion yield.

[0113] Carbon fiber is subjected to tension during production, and its structure is oriented, so it has anisotropy of mechanical and electrical properties.

[0114] In some embodiments, the diameter of the cured matrix 521 of the electrode component 52 is larger than the diameter of the conductive fiber 522. The number of conductive fibers 522 is configured as N, and the diameter of the conductive fiber 522 is y. Wherein, N≥100, y<0.2mm.

[0115] This setting makes the number of conductive fibers 522 large and the diameter small, so that the electric field generated by the electrode component 52 is equivalent to the superposition of multiple local tiny electric fields, which can greatly improve the concentration of air anions and enhance the release ability of negative ions.

[0116] At the same time, like charges repel each other, which improves the diffusion ability of negative ions in space and improves the space diffusion range. This also reduces the dependence on auxiliary devices such as fans during the application of the charged microparticle water generating device 5. Referring to FIG. 4, it is a schematic diagram of single tip and multiple tip discharge effective electric field.

[0117] In some embodiments, carbon fiber uses carbon fiber bundle between 1 to 10 microns as electrode material. The fiber bundle in one electrode component 52 contains N carbon fibers, which constitutes a group of multi-tip discharge electric field. Wherein, N is less than 500,000.

[0118] If the number of carbon fibers is too large, it will cause the overall size of the electrode component 52 to be too large, which is not easy to complete the installation of the charged microparticle water generating device 5. Therefore, the number of carbon fibers should be less than 500,000.

[0119] Therefore, the electrode component 52 in the embodiment corresponds to the superimposed combination of multiple tip discharge electrodes, and the effective electric field strength and range thereof is several times, several hundred times or even several thousand times of that of a single tip discharge electrode.

[0120] The cured matrix 521 and the conductive fibers 522 together constitute the main body of the electrode component 52. The emitting tips of the conductive fibers 522 extend to the outside of the cured matrix 521.

[0121] In some embodiments, referring to FIGS. 5 and 6, the conductive fibers 522 and the cured matrix 521 together form a rod shape, and the top end of the electrode rod has the conductive fiber bundle exposed, and the height h at which the conductive fiber bundle is exposed is defined, where 0.01 mm≤h.

[0122] In order to ensure that the electrode top end can generate an effective electric field, the electrode rod top end is thus arranged to have the conductive fiber bundle exposed. The conductive fiber bundle is exposed by at least 0.01 mm, so that the electrode component 52 can generate an effective electric field of air anions or water ions.

[0123] In some embodiments, the top end of the electrode rod has the conductive fiber bundle exposed, and the height h at which the conductive fiber bundle is exposed is defined, where h≤10 mm. In the embodiment, the height at which the conductive fiber bundle is exposed should not be too large. When the height is maintained within a range of less than or equal to 10 mm, the phenomenon of multiple conductive fibers 522 being overlapped, entangled or having inconsistent directions can be avoided, which affects the formation of the electric field.

[0124] Meanwhile, in the embodiment, water is an important source of ionized target product water ions. These waters are partly derived from the air, and more are derived from the supply of the electrode component 52 to the tip electric field. The moisture in the electrode component 52 can be guided to the end of the conductive fiber 522 through the internal channel, similar to the action of a capillary tube. This part of the moisture is used to generate water ions by using the first voltage. In order to ensure sufficient supply of moisture, the height h at which the conductive fiber 522 is exposed should not be too high. Therefore, the height h at which the conductive fiber 522 is exposed is set to be less than 10 mm.

[0125] In some embodiments, the ratio X of the number n of the conductive fibers 522 exposed to the cured matrix 521 to the total number of the conductive fibers 522 is defined, where X is greater than 1%, so that the discharge effect of the electrode component 52 is at least higher than that of the pointed structure electrode in the related art.

[0126] Ideally, the ratio of the number of the exposed conductive fibers 522 is that all the conductive fibers 522 are exposed, which will produce a better superimposed electric field effect. However, due to the operation of the manufacturing process, such as mold forming, fiber bundle cutting, cured matrix 521 filling and the like, some of the conductive fibers 522 may not be exposed. In the embodiment, the ratio of the conductive fibers 522 exposed to the cured matrix 521 is ensured to be more than 1%, which can ensure the discharge effect of the electrode component 52.

[0127] In some embodiments, referring to FIG. 5, the diameter of the bottom of the electrode component 52 is defined as d, and the curvature radius of the arc formed by the plurality of conductive fibers 522 is d / 2, so that when the electrode component 52 is connected to the voltage output component 51, the emitting end generates an electric field to ionize the moisture in the air absorbed by the moisture-absorbing material 523.

[0128] In some embodiments, d≥1 mm. When the diameter of the electrode component 52 is greater than or equal to 1 mm, the number of conductive fibers 522 can be ensured to be appropriate, so that the electrode component 52 generates sufficient electric field strength, so that the ion amount generated by the charged micro-particle water generating device 5 is relatively large, and the cleaning effect is achieved.

[0129] In some embodiments, d≤6 mm. When the diameter of the electrode component 52 is kept within the range of 6 mm, the overall size of the charged micro-particle water generating device 5 is appropriate, and the installation is convenient.

[0130] In some embodiments, the top end of the electrode component 52 can be, but is not limited to, a circular arc shape or a platform shape.

[0131] In some embodiments, the conductive fiber 522 can be a metal fiber.

[0132] In some embodiments, the conductive fiber 522 can be designed using a combination of a high polymer and a metal salt, so that it has good conductivity after absorbing moisture or other design methods that can achieve good conductivity after absorbing moisture.

[0133] In some embodiments, the high polymer includes polyethylene, polypropylene, etc. The metal salt includes LiCl, CaCl2, NaCl, etc.

[0134] In some embodiments, the electrode component 52 further includes a moisture-absorbing material 523. The moisture-absorbing material 523 is arranged at least on the surface of the electrode component 52 to capture moisture in the air and is used for electrode ionization.

[0135] In some embodiments, the moisture-absorbing material 523 is arranged to be composed of MOFs. MOFs is the abbreviation of Metal organic Framework, which is a metal-organic framework compound. MOFs has the advantages of high specific surface area and high active site. Through the design of the ligand of MOFs, it can have higher moisture absorption performance under low humidity conditions. So that the electrode component 52 has the ability to stably release ions in a low humidity environment.

[0136] In some embodiments, the content of MOFs in the water-absorbing material 523 accounts for more than a first parameter, where the first parameter is set to 1%. Since the structure of MOFs is beneficial to the collection of water, but the specific rigid structure of MOFs is not conducive to the storage of a large amount of water. When the content of MOFs is too low, the adsorption capacity of the composite material to the water in the air is poor.

[0137] In some embodiments, the content of MOFs in the water-absorbing material 523 accounts for less than a second parameter, where the second parameter is set to 2.9%. When the content of MOFs is too high, the agglomeration phenomenon and the rigid structure of MOFs cause the water to be concentrated in the voids of MOFs, and the water cannot be transported and stored in the surrounding water storage structure 526 in time, thus causing the decrease of the moisture absorption capacity, and also causing the decrease of the water conductivity of the electrode structure, which cannot efficiently transport the absorbed water to the end of the electrode structure for ionization.

[0138] Referring to FIG. 9, the moisture absorption performance of the electrode within 24 hours is illustrated in different proportions of MOFs in the water-absorbing material 523. As shown in the figure, when the doping amount of MOFs is 1.1-2.9%, the moisture absorption performance of the electrode is better than that of other doping amount proportions, for example, 0-1%.

[0139] In some embodiments, the content of MOFs in the water-absorbing material 523 is 1.1%. The adsorption capacity of the composite material to the water in the air is enhanced relative to other contents.

[0140] In some embodiments, the content of MOFs in the water-absorbing material 523 is 2%. The adsorption capacity of the composite material to the water in the air is enhanced relative to other contents.

[0141] Referring to FIG. 8, the water absorption rate of the electrode component 52, sample 1 and sample 2 in the present application is compared when they are continuously placed in a humidity of 30% RH and a temperature of 25°C for 24 hours. The electrode component 52 in the present application includes the conductive fiber 522 and the solidified matrix 521, where the solidified matrix 521 is doped with MOFs. Sample 1 includes the conductive fiber 522 and the solidified matrix 521 without doping MOFs. Sample 2 is formed by the solidified matrix 521 without doping MOFs.

[0142] As shown in FIG. 8, the electrode component 52 in the present application has strong moisture absorption performance, and the moisture absorption rate within 24 hours reaches 0.17 g·g - 1 , and still has the ability to continue to absorb moisture, which indicates that the water storage structure 526 is successfully formed in the solidified matrix 521, and the water in the air can be captured by the moisture-absorbing functional material and continuously transported to the water storage structure 526 through the surface micropores.

[0143] With time, the moisture in the air is gradually absorbed into the electrode structure, and as the water storage structure 526 inside gradually reaches saturation, the absorption rate gradually slows down, but it still does not reach saturation in 24 hours.

[0144] Since sample 1 includes conductive fibers 522 and a cured matrix 521, and does not include a hygroscopic functional material such as MOFs, it can only rely on the water storage structure 526 and micropores in the small amount of cured matrix 521 to absorb water, and the hygroscopic performance is very limited, with a saturated hygroscopic rate of only 0.013 g·g -1 , and it reaches saturation in 6 hours.

[0145] The electrode component 52 of sample 2 does not include a hygroscopic functional material, and it relies on the surface micropores 525 and the internal water storage structure 526 to absorb water, with a 24-hour hygroscopic rate of 0.09 g·g -1 , and it still has a weak ability to continue to absorb water, so it can be judged that the internal water storage structure 526 is not completely saturated at this time, but due to the lack of efficient ability to capture moisture in the air, its 24-hour hygroscopic rate is almost only half of the technical solution in this embodiment.

[0146] In some embodiments, referring to FIG. 7, the electrode component 52 includes a water storage structure 526. The water storage structure 526 is disposed in the cured matrix 521. The water storage structure 526 is a micron-sized hole generated in the cured matrix 521 due to the lateral expansion and pulling effect during the manufacturing process of the electrode component 52. When the hygroscopic material captures the moisture in the air to saturation, the moisture is stored in the hole in the form of liquid water.

[0147] In some embodiments, the water storage structure 526 is a three-dimensional network structure, and the water storage structure 526 is micron-sized, used to store the absorbed moisture, and can repeatedly absorb and release water without damaging its own structure.

[0148] In some embodiments, the size of the water storage structure 526 is between several microns and tens of microns, and the external moisture can be guided into the water storage structure 526 by surface tension and capillary action, and the internal moisture is prevented from flowing out by gravity.

[0149] In some embodiments, the main components inside the electrode component 52 are conductive fibers 522 and a cured matrix 521, wherein the conductive fibers 522 realize longitudinal conduction and form a local electric field at the end of the conductive fibers 522. Due to the special manufacturing process, the lateral expansion and pulling effect of the electrode component 52 generates micron-sized holes in the cured matrix 521 between the conductive fibers 522 in the electrode component 52, i.e., the water storage structure 526.

[0150] In some embodiments, as shown in FIG. 35, the electrode component 52 includes surface micropores 525 for connecting the water-absorbing material 523 and the water storage structure 526, for conducting the water in the air captured by the water-absorbing material 523 into the water storage structure 526 for storage.

[0151] In some embodiments, referring to FIG. 35, the surface micropores 525 are arranged on the surface of the electrode structure. The moisture on the surface can be transferred to the inside of the electrode component 52 through the surface micropores 525 and stored in the water storage structure 526.

[0152] In some embodiments, the electrode component 52 includes water-conducting channels 524. The water-conducting channels 524 are arranged inside the electrode component 52. The water-conducting channels 524 are located between the solidified matrix 521 and the conductive fibers 522. The water-conducting channels 524 are arranged as elongated channels with a width of microns along the surface of the conductive fibers 522.

[0153] The water-conducting channels 524 in the solidified matrix 521 material can improve the dispersion of MOFs in the electrode and reduce the performance degradation caused by the agglomeration of MOFs.

[0154] The water-conducting channels 524 are in communication with the water storage structure 526. After the electrode component 52 is connected to the first voltage, the water at the end of the electrode component 52 is ionized to generate water ions, which consumes the water at the end of the electrode component 52. At this time, the water stored in the electrode component 52 can be transported to the end of the electrode component 52 through the water-conducting channels 524 for ionization to generate water ions.

[0155] By arranging the water-conducting channels 524 in the electrode component 52, the water at the emission end of the electrode component 52 can be replenished during the generation of water ions, and unnecessary loss of water is limited.

[0156] The water-conducting channels 524 can assist in the storage and transportation of water. Water molecules in the water-conducting channels 524 are affected by surface tension and capillary action, so that a stable water column is formed in the water-conducting channels 524, and the water is prevented from flowing under the action of gravity.

[0157] In this embodiment, there are micron-level water storage structures 526 between the conductive fibers 522, which are in communication with the surface micropores 525 and are conducive to the water storage of the electrode component 52. The water storage structures 526 are connected to the conductive fibers 522 and can conduct the water along the conductive fibers 522 to the emission tip of the conductive fibers 522.

[0158] By setting the water-absorbing material 523, the water storage structure 526, and the water guide channel 524 to cooperate with each other, the water absorption, storage, and guide capabilities of the electrode component 52 are effectively improved, without the need for other semiconductor refrigeration devices, and the failure rate is lower than that in the related art. Moreover, the charged microparticle water generating device 5 has a wider humidity range of the required working environment and can work under a humidity of 20% or more, so that the application range of the indoor unit of the air conditioner 100 is wider, and the competitiveness of the entire machine is improved.

[0159] In some embodiments, referring to FIG. 7, the water-absorbing material 523 is dispersed in and on the surface of the solidified matrix 521. The hygroscopic material on the outer surface of the electrode component 52 is in contact with air, and can efficiently capture water molecules in the air by taking advantage of its high active sites, achieving high-efficiency hygroscopic effect. The hygroscopic material located inside the electrode component 52 has the function of preserving water.

[0160] The water-absorbing material 523 is incorporated into the solidified matrix 521. Due to the introduction of the water-absorbing material 523, water in the air can be absorbed in a low-humidity environment, providing water raw materials for ionization of the conductive fiber 522.

[0161] In some embodiments, when the water-absorbing material 523 is doped into the solidified matrix 521, the organic ligand can form a hydrogen bond with the material of the solidified matrix 521, and then be uniformly dispersed to achieve the uniformity of the overall performance of the material.

[0162] In addition, the introduction of the water-absorbing material 523 can form a heterostructure with the material of the solidified matrix 521, change the energy band structure of the material, improve the utilization efficiency of water by the electrode component 52, and then improve the negative ion yield.

[0163] In the present application, the electrode component 52 includes a conductive fiber 522 and a solidified matrix 521, wherein the solidified matrix 521 is doped with MOFs. In other words, the electrode component 52 includes a composite material composed of carbon fiber, MOF, and solidified matrix 521.

[0164] The hydroxyl groups of the electrode component 52 in the present embodiment mainly come from the surface hydroxyl-rich pre-treatment of carbon fiber and the hydration network adhesive in the process. The introduction of hydroxyl groups can greatly improve the hydrophilicity of the material itself and enhance the water absorption performance of the material.

[0165] In some embodiments, within a certain humidity range, water in the air is captured by the water-absorbing material 523 incorporated into the solidified matrix 521 into the surface micropore 525, and then introduced into the water storage structure 526. When the electrode component 52 and the voltage output component 51 are connected, the emission tip of the conductive fiber 522 ionizes water to generate water ions, so as to consume the water at the emission end of the electrode component 52, and a pressure difference is formed between the emission end and the bottom end of the electrode component 52.

[0166] The water in the water storage structure 526 is transported to the emitting end of the electrode component 52 through the water guide channel 524 to replenish the water required for ionization.

[0167] In some embodiments, when the water absorption material 523 captures the water in the air to saturation, the water is stored in the form of liquid water in the hole. The moisture absorption characteristics of the electrode component 52 can be further improved, and the moisture absorption characteristics of more than 10% of the mass of the electrode component 52 can be achieved even in a dry environment with an ambient humidity of 30% RH.

[0168] The water stored in the electrode component 52 can diffuse longitudinally along the conductive fiber 522. Under the action of an electric field, the emitting tip of the conductive fiber 522 generates a local electric field with the air, and the water molecules on the surface of the emitting tip of the conductive fiber 522 are ionized into hydroxyl radicals under the action of the electric field. At the same time, the electrons released by the electrode component 52 form negative ions with the air around the electric field. The hydroxyl radicals and negative ions are wrapped by high-pressure atomized nanometer water particles and diffuse into the air.

[0169] The water in the electrode component 52 is continuously supplied to the emitting tip of the conductive fiber 522 to generate water ions, and the water absorption material 523 on the surface of the solidified matrix 521 simultaneously captures the water in the air to replenish the water for the electrode component 52, forming a water replenishment and consumption cycle.

[0170] In some embodiments, the electrode component 52 includes the water absorption material 523. Referring to FIG. 10, the water absorption material 523 is combined with the conductive fiber 522. The water absorption material 523 is attached to the conductive fiber 522. The water absorption material 523 on the conductive fiber 522 located on the outer surface of the solidified matrix 521 is in contact with the air, and its high active site advantage can capture the water in the air to achieve high-efficiency moisture absorption.

[0171] In some embodiments, the MOFs are attached to the conductive fiber 522 using a process such as in-situ growth, which can improve the hydrophilic ability of the surface of the conductive fiber 522, greatly improve the hydrophilic ability of the water guide channel 524 located on the surface of the conductive fiber 522, and further greatly improve the transmission performance of the water in the water guide channel 524.

[0172] In some embodiments, within a certain humidity range, the water in the air enters the water storage structure 526 through the capture of the water absorption material 523 on the conductive fiber 522 into the surface micropore 525.

[0173] When the electrode component 52 and the voltage output component 51 are connected, the emitting tip of the conductive fiber 522 ionizes the water to generate water ions to consume the water at the emitting end of the electrode component 52, and a pressure difference is formed between the emitting end and the bottom end of the electrode component 52.

[0174] The water in the water storage structure 526 is transported to the emitting end of the electrode component 52 through the water guide channel 524 to replenish the water needed for ionization.

[0175] In some embodiments, within a certain humidity range, the water in the air is guided into the surface micropore 525 through the water absorption material 523 on the conductive fiber 522, and then into the water guide channel 524.

[0176] When the electrode component 52 and the voltage output component 51 are connected, the emitting tip of the conductive fiber 522 ionizes the water to generate water ions, which consume the water at the emitting end of the electrode component 52, and a pressure difference is formed between the emitting end and the bottom end of the electrode component 52.

[0177] The water in the water guide channel 524 is transported to the emitting end of the electrode component 52 to replenish the water needed for ionization.

[0178] In some embodiments, when the water absorption material 523 saturates the water in the air, the water is stored in the form of liquid water in the hole. Further improving the moisture absorption characteristics of the electrode component 52, even in a dry environment with an ambient humidity of 30% RH (Relative Humidity), the moisture absorption characteristics of the electrode component 52 can still be greater than 10% of the mass of the electrode component 52.

[0179] The water stored in the electrode component 52 can diffuse longitudinally along the conductive fiber 522. Under the action of the electric field, the emitting tip of the conductive fiber 522 generates a local electric field with the air, and the water molecules on the surface of the emitting tip of the conductive fiber 522 are ionized into hydroxyl radicals under the action of the electric field. At the same time, the electrons released by the electrode component 52 form negative ions with the air around the electric field. The hydroxyl radicals and negative ions are wrapped in high-pressure atomized nanometer water particles and diffuse into the air.

[0180] The water in the electrode component 52 continuously supplies the emitting tip of the conductive fiber 522 to generate water ions, and the water absorption material 523 on the surface of the conductive fiber 522 simultaneously captures the water in the air to replenish the water for the electrode component 52, forming a water replenishment and consumption cycle.

[0181] When the voltage output component 51 does not supply power to the electrode component 52, the charged microparticle water generating device 5 is in a condensed water state, and the water absorption material 523 of the electrode component 52 can adsorb the water in the air on the surface of the electrode component 52. Using the pore structure and high specific surface area of the lateral pores, the water molecules on the surface of the electrode component 52 can be stored in the interior of the electrode component 52 by capillary principle.

[0182] When the voltage output component 51 supplies power to the electrode component 52, the charged micro-particle water generating device 5 releases ions. Referring to FIG. 11, the emission tip of the conductive fiber 522 generates a negative high-voltage electric field, the moisture in the interior of the electrode component 52 is atomized by the high voltage and released through the transverse aperture and the longitudinal aperture, and is ionized into hydroxyl radicals, while the electrons released by the electrode component 52 form negative ions with the air around the negative high-voltage electric field, and the hydroxyl radicals and the negative ions are wrapped by the nanometer water ions atomized by the high voltage, and diffuse into the air.

[0183] That is, part of the water in the interior of the electrode component 52 is excited by the negative high-voltage electric field to become hydroxyl radicals, which are wrapped by water particles to form hydroxyl charged micro-particle water. The electrons released by the electrode component 52 react with oxygen O2 in the air to generate negative ions O2-, which are wrapped by water particles to form negative ion O2- charged micro-particle water. Both the hydroxyl radical and the negative ion O2- charged micro-particle water have air purification effects of sterilization and odor removal, and because the outer layer is wrapped by nanometer water particles, they have a longer action distance and better action effect.

[0184] Among them, when the first voltage source supplies power to the electrode component 52, the water-absorbing material 523 can also absorb the moisture in the air, and can generate charged micro-particle water through the same path as described above.

[0185] After the emission tip of the conductive fiber 522 is ionized, the moisture is consumed, and the water in the interior of the conductive fiber 522 can be absorbed to the emission tip by the pressure difference between the interior and the tip of the conductive fiber 522 to continuously supply ionization. The electrode component 52 can continuously supply water and store it, which saves the trouble of regularly adding water to the water storage function component in the related art, and avoids the disadvantages of obtaining condensed water through a structure load and a high-cost semiconductor refrigeration module in the related art.

[0186] The indoor unit provided in the embodiment has an air purification function, and the charged micro-particle water generating device 5 is installed at the air outlet 3, so that the charged micro-particle water generated by the charged micro-particle water generating device 5 is blown into the room, improving the air purification effect.

[0187] Referring to FIG. 34, the charged micro-particle water generating device 5 further includes a base 53, one end of the electrode component 52 away from the emission tip is installed on the base 53, the base 53 has a through hole 531 for the high-voltage wire 60 to pass through, and the voltage output component 51 is connected with the electrode component 52 through the high-voltage wire 60 passing through the through hole 531. The base 53 plays a role of mounting and supporting the electrode component 52, and the base 53 is made of an insulating material.

[0188] In some embodiments, the base 53 is installed at the air outlet 3 of the indoor unit.

[0189] In the embodiment, the electrode component 52 and the voltage output component 51 are in a split structure, and the two are connected through the high-voltage wire 60. Of course, in other embodiments, the base 53 can be integrally connected with the voltage output component 51, which shortens the distance between the electrode component 52 and the voltage output component 51, reduces the volume of the charged-particle water generating device 5, and facilitates installation.

[0190] Specifically, in the embodiment, the base 53 is hollow inside and has an open bottom end, and the top end of the base 53 is provided with a through hole 531. The through hole 531 is protrudingly arranged at the top end of the base 53, facilitating connection with the electrode component 52.

[0191] In some embodiments, referring to FIG. 13, the charged-particle water generating device 5 further comprises a connecting cover 54, which is arranged on the base 53. The connecting cover 54 is formed with a mounting position 541 on the side away from the base 53 for mounting and fixing the electrode component 52, and the mounting position 541 is arranged opposite to and in communication with the through hole 531.

[0192] In the embodiment, the connecting cover 54 is hollow inside and has an open top end, and the mounting position 541 is protrudingly arranged on the connecting cover 54 and arranged opposite to the through hole 531, and the through hole 531 extends into the mounting position 541.

[0193] In order to realize detachable connection of the connecting cover 54 and the base 53, a connecting groove 56 is further arranged on the inner side wall of the connecting cover 54, and a buckle 55 is arranged on the outer wall of the base 53, and the buckle 55 is adaptively connected with the connecting groove 56 to connect and fix the connecting cover 54 and the base 53, which is simple and convenient.

[0194] In some embodiments, referring to FIG. 12, in order to realize installation of the charged-particle water generating device 5, the charged-particle water generating device 5 further comprises a mounting plate 57, which is connected with the connecting cover 54 and is adapted to be mounted on the indoor housing 1 and located at the air outlet 3.

[0195] In order to improve the release capacity of the charged-particle water generating device 5, the electrode component 52 can be configured with one or more to improve the release capacity of negative ions. The plurality of electrode components 52 are arranged in parallel. As shown in FIG. 2, the electrode component 52 is configured with two. Correspondingly, the number of the through hole 531 of the base 53 and the mounting position 541 on the connecting cover 54 is configured to be the same as the number of the electrode component 52.

[0196] In some embodiments, the air deflector 4 is movably arranged at the air outlet 3 to open or close the air outlet 3. When the air deflector 4 opens the air outlet 3, the air deflector 4 can also be used to guide the heat-exchanged air discharged through the air outlet 3.

[0197] In some embodiments, the indoor unit further includes multiple air guide vanes. These multiple air guide vanes are oscillatingly disposed within the air outlet 3 along the length of the housing, and are spaced apart along the length of the housing. By providing multiple air guide vanes, the airflow direction at the air outlet 3 can be adjusted, thereby dispersing and guiding the airflow blown out of the air outlet 3, and thus blowing ions to a designated area for diffusion. This also improves the comfort and uniformity of the airflow.

[0198] In some embodiments, a plurality of conductive fibers 522 are dispersedly disposed at one end of the cured substrate 521 so that the electrode component 52 forms an emitting end with exposed conductive fibers 522. The outer edge of the emitting end is configured as an arc-shaped structure.

[0199] When the indoor unit is in normal use, the airflow after heat exchange passes through the charged microparticle water generator 5 and is blown out through the air outlet 3. The heat-exchanged air can carry ions out, which can facilitate the blowing out of negative ions and also blow the ions further.

[0200] Ions, such as oxygen ions, diffuse into the indoor space under the influence of electric field force and heat exchange airflow force, and collide and combine with bacteria, viruses and other organisms in the indoor space. By destroying the cell protein structure, they kill bacteria and inactivate viruses. At the same time, negatively charged ions can combine with positively charged particulate matter suspended in the indoor space and settle down, thus purifying the air and keeping the indoor air fresh and clean.

[0201] In some embodiments, the indoor fan operates in reverse, allowing indoor air to enter the interior of the casing through the opening and closing of the air outlet 3 and the air guide plate 4. The air then flows through the charged microparticle water generator 5. Ions diffuse into the interior space of the casing under the influence of the electric field and the airflow, making full contact with the indoor heat exchanger, indoor fan, etc. The negative ions collide and combine with bacteria and viruses attached to their surfaces, destroying the bacterial protein structure and thus killing bacteria and inactivating viruses. In this way, the charged microparticle water generator 5 can also kill bacteria and inactivate viruses on the internal components of the air conditioner 100.

[0202] In some embodiments, the electrode component 52 includes conductive fibers 522 and a cured substrate 521. The conductive fibers 522 are used to communicate with the high-voltage wire 60 to conduct electrical energy to the ends of the conductive fibers 522, forming a local electric field. The cured substrate 521 serves to shape and cure the material.

[0203] In some embodiments, the solidified matrix 521 is an insulator. In this case, it is necessary to ensure that each conductive fiber 522 is in effective electrical connection with the high-voltage wire 60, so as to ensure the superposition of the electric field at the end of the conductive fiber 522, and to ensure the ion release amount and ion release stability of the electrode component 52. However, since the conductive fiber 522 is very thin, it is difficult to effectively connect each conductive fiber 522 to the high-voltage wire 60.

[0204] In order to ensure the stable connection between the conductive fiber 522 and the first voltage, in some embodiments, the charged-particle water generating device 5 includes a conductive structure 58. The conductive structure 58 is arranged between the electrode component 52 and the voltage output component 51, and is used to deliver the first voltage to the conductive fiber 522.

[0205] In some embodiments, referring to FIG. 14, the conductive structure 58 includes a plurality of terminal connectors 581. One end of the terminal connector 581 is in electrical connection with the high-voltage wire 60 of the voltage output component 51, and a plurality of conductive fibers 522 form a conductive fiber bundle, which is in corresponding connection with the other end of one terminal connector 581.

[0206] When the voltage output component 51 is used to output the first voltage to the electrode component 52, the first voltage is delivered to the plurality of conductive fibers 522 through the high-voltage wire 60 and the terminal connector 581, so as to form an electric field at the emitting end of the electrode component 52, and to ionize the moisture in the air absorbed by the moisture-absorbing material 523 by using the electric field.

[0207] In some embodiments, the plurality of conductive fibers 522 are divided into a plurality of conductive fiber bundles, and the conductive fiber bundles are in corresponding connection with the terminal connectors 581.

[0208] When the voltage output component 51 is used to output the first voltage to the electrode component 52, the first voltage is delivered to the plurality of conductive fibers 522 through the high-voltage wire 60 and the terminal connector 581, so as to form an electric field at the emitting end of the electrode component 52, and to ionize the moisture in the air absorbed by the moisture-absorbing material 523 by using the electric field.

[0209] In some embodiments, the solidified matrix 521 includes a plurality of conductive components, which are dispersed in the solidified matrix 521, so as to realize the electrical conduction of the solidified matrix 521.

[0210] In some embodiments, referring to FIG. 15, one end of the conductive structure 58 is connected to the voltage output component 51, and the other end of the conductive component is partially or entirely immersed in the solidified matrix 521, so that the conductive structure 58 is in contact connection with the solidified matrix 521 and the partial conductive fiber 522, and the first voltage is delivered to the conductive fiber 522.

[0211] The conductive fiber 522 connected with the conductive structure 58 is defined as the first conductive fiber 5221, and the conductive fiber 522 not in contact with the conductive structure 58 is defined as the second conductive fiber 5222.

[0212] When the voltage output component 51 outputs the first voltage to the electrode component 52, the first voltage is transmitted to the first conductive fiber 5221 through the conductive structure 58.

[0213] The first conductive fiber 5221 and the second conductive fiber 5222 form a transient potential difference, and an electric current is formed in the cured matrix 521 under the action of the conductive structure 58, so that the conductive loop formed between the first conductive fiber 5221 and the second conductive fiber 5222 is in communication with each other. In this way, the second conductive fiber 5222 not in contact with the conductive structure 58 establishes electrical connection with the conductive structure 58 through the conductive loop.

[0214] The first conductive fiber 5221 and the second conductive fiber 5222 are connected to the first voltage to form an electric field at the emitting end of the electrode component 52, and ionize the moisture in the air absorbed by the electrode component 52.

[0215] In an embodiment, if the resistance of the cured matrix 521 is too high, for example, the resistance value of the electrode structure prepared by the ordinary cured matrix 521 in the cross-sectional direction reaches 100,000 ohms or more, and the conductive fiber 522 in communication with the pointed structure is divided by the cured matrix 521, the farther the conductive fiber 522 from the pointed structure, the lower the voltage value, resulting in insufficient electric field at the emitting end of the conductive fiber 522, and finally insufficient water ion concentration.

[0216] In this case, a conductive component can be introduced into the cured matrix 521, which can be the conductive ion 528.

[0217] In some embodiments, the conductive ion 528 is introduced by adding an alkaline solvent during the preparation of the cured matrix 521, for example, the alkaline solvent can be set as potassium hydroxide, sodium hydroxide.

[0218] So that after the curing of the cured matrix 521, the coordination between the conductive ion 528 (herein referred to as potassium ion or sodium ion) and the carbon fiber in the cured matrix 521 can effectively reduce the cross-sectional resistance value of the cured matrix 521, and improve the conductive performance of the cured matrix 521.

[0219] In some embodiments, the preparation process of the solidified matrix 521 is as follows: polyacrylic acid is dissolved in deionized water, and the pH value is adjusted to between 6 and 8 by an alkaline agent (optionally KOH, NaOH, etc.), and then a crosslinking agent and an initiator are added. The addition of the alkaline agent, such as KOH, not only adjusts the pH value, but also effectively reduces the cross-sectional resistance of the electrode after solidification, thereby improving the conductivity of the solidified matrix 521.

[0220] In this embodiment, the addition ratio of the alkaline agent is in the range of 30% to 70% of the alkaline agent / acidic agent, wherein the alkaline agent can be KOH, NaOH, etc., and the acidic agent can be acrylic acid, etc.

[0221] In some embodiments, when the voltage output component 51 outputs the first voltage to the electrode component 52, the first voltage is transmitted to the first conductive fiber 5221 through the conductive structure 58.

[0222] In some embodiments, when the voltage output component 51 outputs the first voltage to the electrode component 52, a transient potential difference is formed between the first conductive fiber 5221 and the second conductive fiber 5222, and an electric current is formed in the solidified matrix 521 under the action of the conductive component, so that the first conductive fiber 5221 and the second conductive fiber 5222 are connected in circuit.

[0223] The first conductive fiber 5221 and the second conductive fiber 5222 are connected to the first voltage to form an electric field at the emitting end of the electrode component 52 and ionize the moisture in the air absorbed by the electrode component 52.

[0224] In some embodiments, referring to FIG. 16, when the voltage output component 51 outputs the first voltage to the electrode component 52, a transient potential difference is formed between the second conductive fiber 5222 and the first conductive fiber 5221, and in the solidified matrix 521 between the first conductive fiber 5221 and the second conductive fiber 5222, the conductive ions 528 move to the first conductive fiber 5221, and the electrons move to the second conductive fiber 5222, forming a circuit connection between the first conductive fiber 5221 and the second conductive fiber 5222, so that all the conductive fibers 522 can be connected to the first voltage to provide a high voltage for the electrode component 52 to ionize the moisture in the air absorbed by the electrode component 52.

[0225] Referring to FIG. 17, potassium ions are taken as an example. When the conductive structure 58 is connected to the first voltage, which can be a negative voltage, a transient potential difference is formed between the conductive structure 58 and the conductive fiber 3411A near it, and in the solidified matrix 521 between them, the electrons move to the conductive fiber 3411A, and the K+ moves to the sharp structure, forming a circuit connection, and the conductive fiber 3411A is connected to the negative high voltage.

[0226] Similarly, the conductive fiber 3411A and the conductive fiber 3411B form a potential difference, and in the solidified matrix 521 between the two, electrons move to the conductive fiber 3411B, and K+ moves to the conductive fiber 3411A, forming a circuit connection, and the conductive fiber 3411B is connected to the negative high voltage.

[0227] By analogy, the outermost conductive fiber 3411Z is connected to the negative high voltage.

[0228] The cross-sectional resistance value of the electrode component 52 obtained in the above embodiment can be less than 250 ohms, and all the conductive fiber bundles in the electrode component 52 can form an effective local electric field and effectively release water ions.

[0229] In some embodiments, the conductive component of the solidified matrix 521 is a conductive material 527.

[0230] In some embodiments, referring to FIG. 22, the conductive material 527 is a spherical conductive material 527. For example, carbon powder, graphene powder, etc.

[0231] In some embodiments, referring to FIG. 23, the conductive material 527 is a short rod-shaped conductive material 527. For example, short carbon fibers, etc.

[0232] In some embodiments, the conductive material 527 is introduced in the following way: during the preparation of the solidified matrix 521, the conductive material 527 is added so that the conductive material 527 is suspended or floated inside the solidified matrix 521.

[0233] After the electrode component 52 is powered on, the conductive material 527 is used to realize the electrical connection between the conductive fibers 522.

[0234] The coordination of the conductive material 527 and the carbon fibers in the solidified matrix 521 can effectively reduce the cross-sectional resistance value of the solidified matrix 521 and improve the conductive performance of the solidified matrix 521.

[0235] Referring to FIGS. 20-21, the conductive material 527 forms a conductive material layer 529 in the solidified matrix 521, and the thickness of the conductive material layer 529 is defined as H 导电层 , and the diameter of the conductive fiber 522 is defined as D 纤维 , where H 导电层 > 5 × D 纤维 . To ensure effective contact between the conductive material 527 in the conductive material layer 529 and form good conductivity inside the solidified matrix 521. In this embodiment, the conductive material layer 529 is added in the solidified matrix 521. By adding a material that does not react with the solidified matrix 521 and has good conductive performance to the solution when the solidified matrix 521 is in a solution mixing state during the preparation of the solidified matrix 521.

[0236] During the curing reaction of the solidifying matrix 521 and the conductive fiber 522, the electrode component 52 is placed vertically (or nearly vertically, the electrode rod is at an angle of 60°-120° with the horizontal plane) as a whole. After the curing reaction is completed, the filled conductive material 527 will be deposited into a layer, i.e., the conductive material layer 529, the small particles in the conductive material layer 529 are connected to each other and can be in contact with the conductive structure and the conductive fiber 522 in the electrode component 52, forming good electrical conductivity.

[0237] In some embodiments, the position of the conductive material layer 529 in the electrode rod is not limited to the bottom. Since the conductive material 527 has a certain gravity, the position of the conductive material 527 in the solidifying matrix 521 can be controlled by controlling the placement of the electrode component 52, the density of the conductive material 527, and the amount of the conductive material 527 during the preparation of the electrode component 52 during the introduction of the conductive material 527.

[0238] In some embodiments, if the density of the conductive material 527 is less than the density of the solidifying matrix 521, the conductive material 527 will float or suspend inside the solidifying matrix during the curing reaction. In this way, the conductive material layer 529 will be formed at the upper part of the electrode rod.

[0239] In this embodiment, referring to FIG. 24, when the conductive material 527 is formed at the emitting end of the solidifying matrix 521, the conductive material 527 forms a conductive material layer 529 in the solidifying matrix 521, and the thickness of the conductive material layer 529 is defined as H 导电层 . The height of the electrode component 52 is H 棒 . The conductive structure 58 can be provided as a pointed structure, and the height of the pointed structure is H 针 . Then H 导电层 >H 棒 -H 针 . To ensure that the conductive material layer 529 can effectively communicate the pointed structure with each conductive fiber 522 in the electrode component 52, to ensure that the electric field output by the electrode component 52 meets the ionization requirement.

[0240] In some embodiments, if the density of the conductive material 527 and the density of the composition of the solidifying matrix 521 are approximately the same, the conductive material 527 is uniformly dispersed in the solidifying matrix, and the conductive material layer 529 has no clear boundary. At this time, it can be considered that H 导电层 =H 棒 .

[0241] In some embodiments, the conductive material layer 529 is realized by adding a blended raw material that can improve the electrical conductivity of the solidifying matrix 521 during the formation of the solidifying matrix 521.

[0242] In some embodiments, the conductive structure 58 is configured as a pointed structure, which is partially or entirely inserted into the electrode component 52 to connect the electrode component 52 to the first voltage.

[0243] In some embodiments, the pointed structure is inserted from the bottom of the electrode component 52 and partially inserted into the electrode component 52 to ensure the effective connection between the pointed structure and the conductive fiber 522 and the solidified matrix 521.

[0244] In some embodiments, the periphery of the pointed structure is configured as a slope to facilitate the insertion into the electrode component 52 and the close connection with the conductive fiber 522 and the solidified matrix 521, thereby ensuring the stable input of the first voltage.

[0245] In the present embodiment, the pointed structure is partially inserted into the electrode component 52 to avoid affecting the overall strength of the electrode component 52.

[0246] In FIG. 18, the diameter of the electrode component 52 is defined as D 棒 , and the height of the electrode component 52 is defined as H 棒 .

[0247] In FIG. 19, the height of the pointed structure is defined as H 针 , the height of the needle tip of the pointed structure is defined as H 针尖 , the diameter of the pointed structure is defined as D 针 , the diameter of the conductive fiber 522 is defined as D 纤维 , the average distance between the conductive fibers 522 is defined as l2, and the closest distance between the conductive fiber 522 and the pointed structure is defined as l1. In some embodiments, the diameter relationship between the conductive fiber 522, the pointed structure, and the electrode component 52 is: D 纤维 <D 针 <D 棒 / 3.

[0248] By setting D 针 <D 棒 / 3, it can be avoided that the diameter of the pointed structure is too large during the insertion of the pointed structure into the electrode component 52, which causes the electrode component 52 to crack and affects the overall strength of the electrode component 52.

[0249] By setting D 纤维 <D 针 , not only the requirements for the pointed structure can be reduced, but also the pointed structure can connect multiple conductive fibers 522 at the same time to ensure the stability of the output of the first voltage of the local conductive fiber 522.

[0250] In some embodiments, the ratio of the conductive structure 58 and the solidified matrix 521 can be less than 1:2 to avoid the loss of the moisture absorption ability of the electrode structure as much as possible.

[0251] In some embodiments, the conductive fibers 522 are longitudinally dispersed uniformly, and the average distance between each fiber and the nearest surrounding fiber is l2, and l2 针 And it is ensured that the distance between more than 50% of the conductive fibers 522 and the nearest surrounding fiber is less than 2xl2, so as to ensure that the solidified matrix 521 has good conductivity under the action of potassium ions and the like.

[0252] In some embodiments, in order to ensure sufficient contact between the pointed structure and the solidified matrix 521, and to ensure the convenience of inserting the pointed structure into the solidified matrix 521, the top end of the pointed structure should be designed as a sharp needle, and H 针尖 >2xD 针 Therefore, the conductive fibers 522 that are not connected to the pointed structure are conductive through potassium ions in the solidified matrix 521 to be connected to the first voltage.

[0253] In some embodiments, in order to ensure the contact area between the pointed structure and the solidified matrix 521, and to ensure the fixing effect of the pointed structure on the electrode rod and the stability of the connection, the pointed structure should be inserted into the solidified matrix 521 sufficiently, and H 棒 / 5<H 针 <H 棒 .

[0254] In some embodiments, as shown in FIG. 26, the charged microparticle water generating device 5 further comprises a connecting component 59. The connecting component 59 is arranged at the bottom of the electrode component 52, and the connecting component 59 is connected to the conductive structure 58, for connecting the voltage output component 51 and each conductive fiber 522, so as to conduct the first voltage to the conductive fiber 522. In order to realize stable installation of the conductive structure 58.

[0255] In some embodiments, the connecting component 59 is arranged to be made of metal. The conductive fiber 522 and the connecting component 59 are in effective contact between the end surface of the electrode component 52, so as to avoid virtual connection.

[0256] In other embodiments, the connecting component 59 can also be arranged to be conductive glue.

[0257] In some embodiments, the conductive structure 58 comprises a pointed structure and a connecting component 59, the connecting component 59 is arranged at the bottom of the electrode component 52, and the connecting component 59 is connected to the pointed structure, so as to improve the stability of installation of the pointed structure.

[0258] The connecting component 59 is used to connect the negative high-voltage wire 60 and each conductive fiber 522. The first voltage is conducted to each conductive fiber 522, and the first voltage can be a negative voltage.

[0259] In some embodiments, the charged micro-particle water generating device 5 comprises a high-voltage wire 60. One end of the high-voltage wire 60 is connected to the voltage output component 51, and the other end of the high-voltage wire 60 is connected to the conductive structure 58, so as to transmit the first voltage output by the voltage output component 51 to the conductive fiber 522.

[0260] In some embodiments, one end of the high-voltage wire 60 is connected to the voltage output component 51, and the other end of the high-voltage wire 60 is connected to the connecting component 59.

[0261] In some embodiments, referring to FIG. 26, the conductive structure 58 is provided in a plurality of forms. The plurality of conductive structures 58 are combined with the connecting component 59. An example is shown in the figure as a pointed structure. The pointed structure and the connecting component 59 are combined to have the effects of conduction and fixed connection.

[0262] In some embodiments, the diameter of the connecting component 59 is the same as the diameter of the electrode component 52, so that the connecting component 59 is connected to as many conductive fibers 522 as possible, and the conduction between the conductive fibers 522 is ensured.

[0263] In some embodiments, the diameter of the connecting component 59 is slightly larger than the diameter of the pointed structure, so as to increase the connection strength between the pointed structure and the connecting component 59, and ensure the reliability of the conduction between the pointed structure and the connecting component 59.

[0264] Due to the increase in the number of conductive structures 58, compared with one conductive structure 58, the height of the conductive structure 58 can be reduced and the diameter of the conductive structure 58 can be reduced without reducing the conduction performance between the conductive structure 58 and the conductive fiber 522. The contact between the conductive structure 58 and the electrode component 52 can be more firm and reliable, and the worker can press the electrode component 52 more easily.

[0265] In some embodiments, referring to FIG. 25, the conductive structure 58 comprises a metal strap 61. The metal strap 61 is wrapped around the periphery of part of the electrode component 52, so that the diameter of the electrode component 52 wrapped with the metal strap 61 is smaller than the diameter of the electrode component 52 without the metal strap 61, so as to shorten the distance between the conductive fibers 522; and the metal strap 61 is in contact with the conductive fiber 522 on the surface of the electrode component 52.

[0266] When the voltage output component 51 transmits the first voltage to the conductive fiber 522 on the surface of the electrode component 52 through the conductive structure 58, a transient potential difference is formed between the conductive fiber 522 on the surface of the solidified matrix 521 and the conductive fiber 522 inside the solidified matrix 521, and an electric current is formed in the solidified matrix 521 under the action of the conductive component, so as to form an electrical circuit communication between the conductive fiber 522 on the surface of the solidified matrix 521 and the conductive fiber 522 inside the solidified matrix 521.

[0267] The conductive fibers 522 on the surface of the cured base 521 and the conductive fibers 522 inside the cured base 521 are connected to the first voltage to form an electric field at the emitting end of the electrode component 52 and ionize the moisture in the air absorbed by the electrode component 52.

[0268] In the above embodiment, the high-voltage wire 60 and the conductive fibers 522 are bundled together by the metal deformation extrusion, the distance between the conductive fibers 522 is shortened, the resistance value between the conductive fibers 522 is reduced, and the first voltage is conducted to the conductive fibers 522.

[0269] In the above embodiment, the high-voltage wire 60 and the conductive fibers 522 are fixedly connected by the metal cable 61, and the pointed structure component and the pointed structure connection point can be omitted.

[0270] In some embodiments, when the conductive component is the conductive ion 528, when the voltage output component 51 outputs the first voltage to the electrode component 52, a transient potential difference is formed between the conductive fibers 522 on the surface of the cured base 521 and the conductive fibers 522 inside the cured base 521, the conductive ion 528 moves to the conductive fibers 522 on the surface of the cured base 521, and the electron moves to the conductive fibers 522 inside the cured base 521. The conductive fibers 522 on the surface of the cured base 521 and the conductive fibers 522 inside the cured base 521 form an electrical connection to enable all conductive fibers 522 to connect to high voltage and provide high voltage to the electrode component 52 to ionize the moisture in the air absorbed by the electrode component 52.

[0271] In some embodiments, the charged microparticle water generating device 5 further comprises a voltage output component 51. The voltage output component 51 is connected to the electrode component 52 to provide the first voltage to the electrode component 52.

[0272] The moisture in the electrode component 52 is ionized by the first voltage to form charged microparticle water, which has a charge and hydroxyl radicals generated by ionized water, thereby improving the air purification effect.

[0273] A power switch is electrically connected between the voltage output component 51 and the electrode component 52, and is used to control the closing or opening of the circuit between the electrode component 52 and the voltage output component 51, thereby controlling the power-on or power-off of the electrode component 52. This setting can realize the charged microparticle water generating device 5 to control the power-on or power-off through the power switch, which is simple and convenient.

[0274] In some embodiments, the voltage output component 51 can be electrically connected to the electric control board of the indoor unit of the air conditioner 100.

[0275] The voltage output component 51 has a high voltage output end outputting negative voltage and a grounding electrode, the high voltage output end is connected with the electrode component 52 through a wire to provide a negative voltage of 0.3Kv-3.5KV, so that a negative high voltage electric field is formed between the electrode component 52 and the grounding electrode, thereby making the electrode component 52 generate hydroxyl charged micro-particle water and negative ion charged micro-particle water.

[0276] Referring to FIG. 27, the voltage output component 51 comprises an oscillation circuit. The oscillation circuit comprises a triangular wave output circuit 512. The input end of the triangular wave output circuit 512 is used to connect an external power supply. The output end of the triangular wave output circuit 512 is used to output a triangular wave with stable frequency.

[0277] The external power supply is a direct current 12V power supply, which can be provided by the electric control board of the indoor unit, and does not need to be connected with an external power supply, and the structure is simple. After the power supply input line is connected with the external power supply, 12V direct current is input to the oscillation circuit.

[0278] Referring to FIG. 27, the oscillation circuit further comprises a PWM signal output circuit 513. The PWM signal output circuit 513 is used to convert the received triangular wave into a PWM signal and output. Under the control of the stable PWM signal, the transformer 517 secondary coil outputs a high voltage with stable frequency to output a stable high voltage to the electrode component 52, thereby ensuring the ion release concentration.

[0279] Compared with the problem of unstable oscillation frequency of the high voltage generation circuit realized by the transformer feedback type oscillation circuit in the embodiment, the oscillation frequency can be accurately controlled and adjusted by adjusting the components. Therefore, the stable release of ions is ensured, and the control of the ion release amount is realized.

[0280] In some embodiments, the frequency of the output high voltage can be adjusted by adjusting the frequency of the triangular wave output by the triangular wave output circuit 512, thereby realizing the influence on the ion release amount.

[0281] In some embodiments, when the required ion generation amount is high, the oscillation frequency is increased, and the number of pulses generated per unit time is increased, the number of pulses is high, and the ion generation amount is correspondingly increased. Referring to FIGS. 31-32, the voltage pulse waveforms corresponding to different oscillation frequencies are shown. In FIG. 31, the oscillation frequency is low, the number of pulses is small, and the ion generation amount is relatively small. In FIG. 32, the oscillation frequency is high, the number of pulses is high, and the ion generation amount is relatively high.

[0282] In some embodiments, the frequency of the PWM signal is different, and the number of negative high-voltage pulses generated after the rectifier circuit is different. In some embodiments, in the case where the output voltage amplitude of the secondary side of the transformer 517 is the same, the higher the oscillation frequency, the more negative high-voltage pulses generated per unit time, and the more water ions generated. The lower the oscillation frequency, the fewer negative high-voltage pulses generated per unit time, and the fewer water ions generated.

[0283] In addition, considering the limitations of module structure and component performance, the size of the high-frequency transformer is not easy to be too large, so its voltage conversion ratio is not easy to be too large, so the voltage conversion ratio will be limited.

[0284] In the case where the external power supply is determined, the amplitude of its output voltage will also be limited. Due to the limitations of device specifications and performance, the oscillation frequency of the circuit will also be limited. Therefore, after the amount of water ion release is determined, the transformer 517 voltage conversion ratio and component performance are considered to design the circuit.

[0285] In some embodiments, when the required ion yield is low, the oscillation frequency is reduced, and the number of pulses generated per unit time is reduced, and the ion yield is correspondingly reduced.

[0286] In the above embodiments, by adjusting the circuit parameters, the voltage output component 51 can output voltages with different amplitudes and frequencies, and control the amount of water ion release.

[0287] In some embodiments, the voltage output component 51 includes a drive circuit 514. The drive circuit 514 is used to compensate for the poor load capacity of the comparator and the inability to drive the switch component.

[0288] The drive circuit 514 includes a push-pull circuit. The input end of the push-pull circuit is connected to the PWM signal output circuit 513, and the output end of the push-pull circuit outputs an amplified PWM signal.

[0289] The voltage output component 51 includes a switching device 515. In some embodiments, the switching device 515 includes a MOS tube U2. The MOS tube U2 is controlled by the PWM signal to switch at high frequency.

[0290] In some embodiments, the switching device 515 can also be an IGBT or other switching device.

[0291] The voltage output component 51 includes a voltage boosting circuit. The voltage boosting circuit is used to boost the output voltage to achieve the required ionization electric field strength of the electrode component 52.

[0292] The voltage boosting circuit includes a transformer 517. The primary side of the transformer 517 is connected to the output of the switching device 515, and the secondary side of the transformer 517 is connected to the electrode component 52. The transformer 517 is used to receive the pulse-shaped voltage and output the pulse-shaped voltage after boosting the voltage.

[0293] The MOS transistor U2 generates the pulse-shaped voltage on the primary side of the transformer 517. The pulse-shaped voltage is boosted by the transformer 517 and a high voltage is generated on the secondary side of the transformer 517. The high voltage is applied to the electrode component 52 to generate the negative ions.

[0294] In some embodiments, referring to FIG. 27, the high-voltage output circuit includes a rectifier circuit 519. The high voltage generated on the secondary side of the transformer 517 is rectified by the rectifier circuit 519 and applied to the electrode component 52 to generate the negative ions.

[0295] Referring to FIG. 28, in some embodiments, the voltage boosting circuit includes at least one voltage doubling circuit 518 to perform voltage doubling. In this embodiment, the voltage can be boosted twice by the voltage doubling circuit 518 before being applied to the electrode component 52.

[0296] Referring to FIG. 28, the voltage boosting circuit includes a diode voltage doubling circuit 518. By adjusting the voltage boosting ratio of the transformer 517 or the number of stages of the voltage doubling circuit 518, the output voltage of the electrode component 52 can be adjusted at the same oscillation frequency. At the same circuit structure, the higher the voltage of the electrode component 52, the greater the amount of ions released.

[0297] Referring to FIGS. 29-30, the test waveforms of the electrode component 52 at different voltage boosting ratios are shown.

[0298] In some embodiments, when the oscillation frequency is increased, the number of pulses generated per unit time is increased, the number of pulses is high, and the amount of ions generated is correspondingly increased. Conversely, when the oscillation frequency is decreased, the number of pulses generated per unit time is decreased, the number of pulses is low, and the amount of ions released is decreased.

[0299] The MOS transistor U2 is switched under the control of the PWM signal, and the power supply returns to the power supply ground through the MOS transistor U2 on the primary side of the transformer 517. During the switching of the MOS transistor U2, the pulse-shaped voltage generated is boosted by the transformer 517 and a high voltage is output on the secondary side. Due to the fast switching of the MOS transistor U2, high-frequency oscillation is generated on the primary side of the transformer 517.

[0300] In some embodiments, when the oscillation frequency is constant, the voltage boosting ratio of the transformer 517 is increased, the voltage peak generated on the secondary side of the transformer 517 is increased, the output voltage applied to the electrode component 52 after rectification is increased, and the amount of water ions released is increased.

[0301] In some embodiments, the output voltage peak on the electrode component 52 is increased by the voltage doubling circuit 518 to increase the release amount of water ions.

[0302] In some embodiments, the output voltage peak on the electrode component 52 is reduced by reducing the voltage boosting ratio of the transformer 517 or without the voltage doubling circuit to reduce the release amount of water ions. As shown in FIGS. 29-30, the waveform of the electrode component 52 under different voltage boosting ratios of the transformer 517 is compared, where V2 < V1.

[0303] In some embodiments, the voltage output component 51 includes a resonance circuit 520 to reduce the influence of resonance on high voltage.

[0304] In some embodiments, referring to FIG. 33, a stable PWM signal can also be generated by the MCU, the frequency of the PWM signal is set by the program as needed, and the PWM signal controls the driving circuit 514 to drive the MOS tube U2 to work.

[0305] Compared with the high-voltage output circuit realized by the transformer 517 feedback type oscillation circuit in the related art, the voltage output component 51 in the embodiment has stable oscillation frequency, and the oscillation frequency can be accurately controlled and adjusted by adjusting the resistance value of the component, to realize accurate control of the release amount of ions. At the same time, the resonance circuit 520 is designed for the oscillation generated by the high-frequency switch, so that the high voltage output by the voltage output component 51 is not affected by resonance.

[0306] In some embodiments, the frequency, pulse number, and size of the first voltage of the PWM signal can be controlled according to the detected indoor air state or pollution degree, to control the ion release concentration.
