Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air handling equipment technology, specifically referring to an air conditioner. Background Technology

[0002] Currently, most air conditioners with air purification functions use negative ion generators for sterilization. The main principle is to release a large number of negatively charged particles to physically settle bacteria. However, they are less effective at removing larger allergens such as mold, and have almost no effect on gaseous pollutants such as formaldehyde and benzene compounds. Therefore, their overall air purification effect is relatively poor. Utility Model Content

[0003] The technical problem to be solved by this application is to provide an air conditioner that is beneficial to improving the air purification effect of the air conditioner.

[0004] This application provides an air conditioner, including: a housing with an air inlet; and an air purification module disposed at the air inlet, the air purification module including a plasma generating module and a catalyst module; the catalyst module is located downstream of the plasma generating module and is configured to work in conjunction with the plasma generating module to purify the air entering the housing.

[0005] The air conditioner provided in this application embodiment has an air purification module installed at the air inlet of the casing. The air purification module includes a plasma generation module and a catalyst module. The plasma generation module can discharge to generate high-energy plasma composed of high-energy electrons, positive and negative ions, and active particles (such as strong oxidizing free radicals), as well as ozone. The extremely high energy of the high-energy plasma and the high oxidizing properties of ozone can then be used to kill bacteria and viruses. Furthermore, the high-energy electrons and active particles can collide with allergens such as mold molecules in the air, destroying the cellular structure of these allergens and rendering them inactive, thereby killing them. In addition, the plasma generation module and the catalyst module work synergistically to broadly decompose gaseous pollutants such as formaldehyde and benzene compounds, thereby removing these pollutants from the air. Therefore, the air conditioner can not only kill bacteria and viruses but also kill allergens such as mold and remove gaseous pollutants, thus improving the air purification effect of the air conditioner.

[0006] Based on the above technical solution, the following improvements can be made to this application.

[0007] In one exemplary embodiment, the plasma generating module includes multiple plasma generating modules arranged in a matrix.

[0008] In an exemplary embodiment, the plasma generating module includes a housing and a discharge assembly disposed within the housing.

The leeward portion has an air outlet, and the windward portion is closed off from the position of the discharge assembly.

[0009] In an exemplary embodiment, the windward portion is provided with an air inlet so that the airflow at the air inlet can enter the housing through the air inlet and be discharged through the air outlet, and the air inlet is offset from the discharge component.

[0010] In an exemplary embodiment, the housing is provided with a first mounting groove, a first wiring groove, a vent corresponding to and communicating with the first mounting groove, and a cable passage corresponding to and communicating with the first wiring groove. The first mounting groove and the first wiring groove are located inside the housing, and the vent and the cable passage are connected to the external space.

Detailed Implementation

[0018] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0019] like Figure 1 As shown in the figure, this application embodiment provides an air conditioner, including: a housing 200 and an air purification module.

[0020] The housing 200 is provided with an air inlet 202. An air purification module is located at the air inlet 202, and the air purification module includes a plasma generating module 100 and a catalyst module 300. The catalyst module 300 is located downstream of the plasma generating module 100 and is configured to work in conjunction with the plasma generating module 100 to purify the air entering the housing 200.

[0021] The air conditioner provided in this embodiment has an air purification module installed at the air inlet 202 of the casing 200. The air purification module includes a plasma generation module 100 and a catalyst module 300. The plasma generation module 100 can discharge to generate high-energy plasma composed of high-energy electrons, positive and negative ions, and active particles (such as strong oxidizing free radicals), as well as ozone. The extremely high energy of the high-energy plasma and the high oxidizing properties of ozone can then be used to kill bacteria and viruses. Furthermore, the high-energy electrons and active particles can collide with allergens such as mold molecules in the air, destroying the cellular structure of these allergens and rendering them inactive, thereby killing allergens such as mold in the air. In addition, the plasma generation module 100 and the catalyst module 300 work synergistically to broadly decompose gaseous pollutants such as formaldehyde and benzene compounds, thereby removing these gaseous pollutants from the air. Therefore, the air conditioner can not only kill bacteria and viruses but also kill allergens such as mold and remove gaseous pollutants, thus improving the air purification effect of the air conditioner.

[0022] In some exemplary embodiments, the plasma generating module 100 includes multiple plasma generating modules 10, which helps to increase the amount of purifying substances released by the plasma generating module 100, thereby improving purification efficiency. The multiple plasma generating modules 10 are arranged in a matrix, which is relatively regular and facilitates the installation and wiring of the plasma purification module.

[0023] In some exemplary embodiments, the orthographic projection of the plurality of plasma generating modules 10 onto the plane containing the windward side of the catalyst module 300 lies within the windward side.

[0024] This allows the purifying substances released by the plasma purification module to pass through the catalyst module 300 as much as possible, thereby achieving a better synergistic effect with the catalyst module 300 and improving the air purification effect of the air conditioner.

[0025] The catalyst module 300 can cover the air inlet 202 to improve purification efficiency; it can also partially cover the air inlet 202 to reduce wind resistance.

[0026] In some exemplary embodiments, such as Figure 1 and Figure 2 As shown, the air purification module also includes a power conversion module 400, which is electrically connected to the plasma generating module 100 and configured to provide high-voltage electricity to the plasma generating module 100. The plasma generating module 100 is electrically connected to the power conversion module via a high-voltage line 500. The power conversion module can convert municipal power into high-voltage electricity and supply it to the plasma generating module 100. Municipal power can come from the air conditioner or from an external power source independent of the air conditioner.

[0027] The power conversion module 400 can be a high-voltage transformer that can supply high-voltage electricity to the plasma generation module 100, so that the plasma generation module 100 discharges to generate high-energy plasma composed of high-energy electrons, positive and negative ions, active particles (such as strong oxidizing free radicals), and ozone.

[0028] When the plasma generating module 100 includes multiple plasma generating modules 10, the multiple plasma generating modules 10 can be connected in series or in parallel.

[0029] In some embodiments, the catalyst module 300 may be mounted to the edge of the air inlet 202 or to the grille of the air inlet 202. The catalyst module 300 may include a rigid frame to facilitate its mounting. A matrix-distributed plasma generating module 10 may be mounted above the catalyst module 300 via a bracket connected to the edge of the air inlet 202, the grille of the air inlet 202, or the catalyst module 300. A high-voltage transformer may be connected to the bracket, the edge of the air inlet 202, the grille of the air inlet 202, or the catalyst module 300.

[0030] In some embodiments, the catalyst module 300 may be mounted to the edge of the air inlet 202 or to the grille of the air inlet 202 and located on the side of the air inlet 202 closer to the impeller. The catalyst module 300 may include a rigid frame to facilitate its mounting. A matrix-distributed plasma generation module 10 may be connected to the edge of the air inlet 202, the grille of the air inlet 202, or the catalyst module 300, and located further away from the impeller relative to the catalyst module 300 or on the side of the air inlet 202 furthest from the impeller. A high-voltage transformer may be connected to the edge of the air inlet 202, the grille of the air inlet 202, or the catalyst module 300.

[0031] In other embodiments, the catalyst module 300 and the plasma generating module 100 are integrated into a single module, which may include a support. The catalyst module 300 may be detachably installed to the lower end of the support, for example, by means of plugging or snapping. The plasma generating module 100 may be detachably installed to the upper end of the support by means of plugging or snapping. The support is then installed to the edge of the air inlet 202 or the grille of the air inlet 202.

[0032] In some exemplary embodiments, the plasma generating module 10 includes a housing 102 and a discharge assembly 104 disposed within the housing 102. The discharge assembly 104 may be, but is not limited to, electrode sheets 1041, such as... Figure 6 and Figure 7 As shown. The outer casing 102 is provided with a windward portion 215 and a leeward portion 216 located inside the air inlet 202 and spaced apart along the airflow direction at the air inlet 202, as... Figure 3 and Figure 4 As shown. The leeward section 216 is provided with an air outlet (such as... Figure 4 (As shown). The windward portion 215 is enclosed in the position directly opposite the discharge assembly 104.

[0033] The outer casing 102 protects the discharge assembly 104. The discharge assembly 104 can discharge to generate plasma, as well as high-energy electrons and active particles. The windward section 215 is positioned to enclose the discharge assembly 104, preventing direct airflow from negatively impacting its performance.

[0034] In some exemplary embodiments, the windward portion 215 is provided with an air inlet 213 (e.g., Figure 3 As shown in the figure, the airflow at the air inlet 202 can enter the housing 102 through the air inlet 213 and be discharged through the air outlet 214. Furthermore, the air inlet 213 is staggered from the discharge assembly 104.

[0035] During use, the airflow at the air inlet 202 enters the outer casing 102 of the plasma generating module 10 through the air inlet 213, and then carries plasma, high-energy electrons, active particles, and other substances out through the air outlet 214. This airflow then enters the room, effectively sterilizing the air. Because the air inlet 213 and air outlet 214 are arranged in the same direction as the airflow at the air inlet 202, the substances generated by the discharge component 104 can be discharged into the room as much as possible, which helps accelerate the diffusion rate of plasma, high-energy electrons, active particles, and other substances, thus improving the sterilization effect. Furthermore, during air conditioning operation, the airflow inside the plasma generating module 10 prevents condensation from forming on the internal surface of the module, keeping the internal structure dry and improving the reliability of the plasma generating module 10.

[0036] In other embodiments, the air inlet 213 may not be provided in the windward part 215. In this case, the substances generated by the discharge component 104 can be released near the air outlet 214 under the negative pressure generated by the airflow or by the diffusion of the plasma itself, and the airflow at the air inlet 202 can be avoided from affecting the discharge component 104.

[0037] In some exemplary embodiments, please refer to the following: Figures 3 to 5 As shown, at least a portion of the vent 214 faces the discharge assembly 104, which facilitates the rapid discharge of substances generated by the discharge assembly 104 into the room. This accelerates the diffusion rate of substances such as plasma, high-energy electrons, and active particles, thereby improving the mold-killing effect.

[0038] In some exemplary embodiments, the flow cross-sectional area of ​​the air outlet 214 is larger than that of the air inlet 213, which facilitates the rapid discharge of substances generated by the discharge component 104 into the room, thereby accelerating the diffusion rate of substances such as plasma, high-energy electrons, and active particles, and thus improving the mold-killing effect.

[0039] In some exemplary embodiments, such as Figure 4 As shown, the air inlet 213 includes multiple first openings 2131, which can prevent the area of ​​a single air inlet 213 from being too large. This is beneficial for preventing external impurities from entering the plasma generating module 10 and protecting the discharge component 104. It is also beneficial for preventing users from accidentally touching the discharge component 104 with their fingers, which could lead to safety accidents.

[0040] Similarly, such as Figure 3As shown, the air outlet 214 includes multiple second openings 2141, which can prevent the area of ​​a single air outlet 214 from being too large. This is beneficial for preventing external impurities from entering the plasma generating module 10 and protecting the discharge component 104. It is also beneficial for preventing users from accidentally touching the discharge component 104 with their fingers, which could lead to safety accidents.

[0041] In some exemplary embodiments, the housing 200 (e.g., on the grille of the air inlet) or on the bracket provided at the air inlet has a mounting port, and the housing 102 snaps into the mounting port. The snap-fit ​​method is simple in structure and easy to install.

[0042] Of course, the installation method of the plasma generating module 10 is not limited to the snap-fit ​​method. It can also be fixed by fasteners (such as screws), or a combination of fasteners and snap-fit, or a combination of fasteners and plug-in, etc. These will not be listed one by one here.

[0043] In some exemplary embodiments, such as Figure 3 and Figure 4 As shown, the housing 102 is provided with a first mounting buckle 2111 and a limiting portion 2115 spaced apart along a first direction. The first mounting buckle 2111 is configured to pass through the mounting opening in a second direction opposite to the first direction and hook onto the housing 200 or the bracket to prevent the housing 102 from disengaging from the housing 200 or the bracket in the first direction. The limiting portion 2115 is located on the side of the mounting opening away from the first mounting buckle 2111 and abuts against the housing 200 or the bracket to prevent the limiting portion 2115 from passing through the mounting opening in the second direction.

[0044] In this way, during assembly, the plasma generating module 10 can be pressed against the mounting port along the second direction, so that the first mounting clip 2111 passes through the mounting port and hooks onto the housing 200 or the bracket. At this time, constrained by the first mounting clip 2111, the plasma generating module 10 cannot move along the first direction and detach from the housing 200 or the bracket; constrained by the limiting part 2115, the plasma generating module 10 cannot continue to move along the second direction and detach from the housing 200 or the bracket. This achieves the installation and fixation of the plasma generating module 10 to the housing 200.

[0045] For example, the second direction is from bottom to top, and the first direction is from top to bottom. Alternatively, the second direction is from back to front, and the first direction is from front to back. Alternatively, the second direction is from diagonally backward to diagonally forward, and the first direction is from diagonally forward to diagonally backward.

[0046] In some exemplary embodiments, such as Figure 4As shown, the first mounting buckle 2111 includes an elastic arm 2112 and a hook 2113 connected to the elastic arm 2112. The elastic arm 2112 undergoes elastic deformation during the process of passing through the mounting opening, and undergoes reset deformation after passing through the mounting opening so that the hook 2113 hooks the housing 200 or the bracket.

[0047] In this way, the first mounting clip 2111 has a relatively large elastic deformation, which makes it easier for the first mounting clip 2111 to pass smoothly through the mounting opening. This helps to reduce the difficulty of the first mounting clip 2111 passing through the mounting opening, thereby improving the installation efficiency of the plasma generating module 10 and the housing 200 or bracket.

[0048] The specific structure of the limiting part 2115 is not limited. In some embodiments, the limiting part 2115 may include a flange 2116.

[0049] For example, a flange 2116 can be provided on the circumferential edge of the outer shell 102, and the flange 2116 can be used to abut against the shell 200 or the bracket to achieve a limiting function.

[0050] Or, such as Figure 3 and Figure 4 As shown, the circumferential edge of the outer shell 102 can be provided with a flange 2116, and the limiting part 2115 includes a plurality of limiting bosses 2117 provided on the flange 2116. The limiting bosses 2117 abut against the shell 200 or the bracket to achieve the limiting function. Since the wall surface of the shell 200 or the bracket can have a certain curvature, and the bottom wall of the outer shell 102 is set to be flat, it is easier to process and form and helps to save installation space. At this time, by providing the limiting bosses 2117 to abut against the shell 200 or the bracket, it is possible to avoid setting the flange 2116 to be a structure with uneven thickness, thus simplifying the structure of the outer shell 102.

[0051] In some exemplary embodiments, such as Figure 3 and Figure 4 As shown, there are multiple first mounting clips 2111, which are divided into two groups to facilitate balanced force distribution on the plasma generating module 10, thereby improving the positional stability and installation reliability of the plasma generating module 10. One group of first mounting clips 2111 is located on the windward side 215, and the other group of first mounting clips 2111 is located on the leeward side 216.

[0052] When the windward section 215 is equipped with an air inlet 213, such as Figure 3 and Figure 4As shown, one set of first mounting clips 2111 is located at the air inlet 213, and the other set of first mounting clips 2111 is located at the air outlet 214. Thus, the air inlet 213 and the air outlet 214 also function as clearance openings, allowing the first mounting clips 2111 relatively large deformation space, facilitating their smooth passage through the mounting opening. This reduces the difficulty of passing the first mounting clips 2111 through the mounting opening, thereby improving the installation efficiency of the plasma generating module 10 with the housing 200 or bracket. When the windward portion 215 does not have an air inlet 213, the set of first mounting clips 2111 located on the windward portion 215 can protrude from the outer surface of the windward portion 215. Of course, the set of first mounting clips 2111 located on the leeward portion 216 can also protrude from the outer surface of the leeward portion 216 and be offset from the air outlet 214.

[0053] like Figure 4 As shown, there is an air passage gap between the first mounting clip 2111 located inside the air inlet 213 and the wall of the air inlet 213, so that the air intake function of the air inlet 213 can be realized normally. There is also an air passage gap between the first mounting clip 2111 located inside the air outlet 214 and the wall of the air outlet 214. Figure 3 As shown, this is to ensure that the air outlet 214 can function properly.

[0054] In one embodiment, such as Figure 4 As shown, the air inlet 213 includes two first openings 2131, and a first mounting buckle 2111 is provided at each of the two first openings 2131. At least a portion of the elastic arm 2112 of the first mounting buckle 2111 is located inside the first opening 2131, and at least a portion of the hook 2113 of the first mounting buckle 2111 is located outside the first opening 2131.

[0055] like Figure 3 As shown, the air outlet 214 includes four second openings 2141, and a second mounting buckle 2121 is provided at each of the two second openings 2141 located at both ends. At least a portion of the elastic arm 2112 of the first mounting buckle 2111 is located inside the second opening 2141, and at least a portion of the hook 2113 of the first mounting buckle 2111 is located outside the second opening 2141.

[0056] In some exemplary embodiments, the housing 102 includes a detachably connected housing body 211 (e.g., Figure 3 and Figure 4 (as shown) and base 212 (as shown) Figure 6 and Figure 7(As shown). The detachable connection structure facilitates the installation of the discharge assembly 104. At least a portion of the housing body 211 is located within the housing 200 or the bracket, with the windward portion 215 and the leeward portion 216 located on the housing body 211, allowing the airflow in the air inlet 202 to enter the housing 102 and flow out through the air outlet 214.

[0057] In some exemplary embodiments, one of the housing body 211 and the base 212 is provided with a second mounting buckle 2121 (e.g., Figure 6 and Figure 7 As shown), the other has a card slot 2114 (as shown). Figure 3 and Figure 4 As shown, the second mounting clip 2121 is engaged in the slot 2114, allowing the housing body 211 to be closed and connected to the base 212. This snap-fit ​​method is simple in structure and easy to assemble. A protrusion 2118 can be provided at the slot 2114 to allow the second mounting clip 2121 to hook onto the protrusion 2118 for reliable fixing.

[0058] Of course, the installation method of the shell body 211 and the base 212 is not limited to the snap-fit ​​method. It can also be fixed by fasteners (such as screws), or a combination of fasteners and snap-fit, or a combination of fasteners and plug-in, etc., which will not be listed here.

[0059] In some exemplary embodiments, such as Figure 6 As shown, the base 212 is provided with a wiring port 2122, and the discharge assembly 104 can be electrically connected to the high voltage transformer outside the housing 102 through the wiring port 2122.

[0060] In some embodiments, the discharge assembly 104 is fixed to the base 212, such as Figure 7 As shown. The specific fixing method is not limited; for example, it can be fixed using fasteners, snap-fit ​​connections, or other methods, which will not be listed here. In one embodiment, the discharge assembly 104 is fixed to the base 212 by four screws.

[0061] In other embodiments, the discharge assembly 104 is fixed to the housing body 211, such as... Figure 5As shown. Thus, even if a small amount of liquid enters the housing 102 in the off state, the liquid will flow towards the base 212 under gravity, rather than flowing against gravity towards the housing body 211. Therefore, in the off state, the surface of the discharge component 104 fixed to the housing body 211 is difficult to be wetted by water, which helps improve the reliability of the plasma generating module 10. Similarly, in the off state, large dust particles are unlikely to accumulate on the surface of the discharge component 104. The specific fixing method is not limited; for example, it can be fixed by fasteners, by snap-fit, or by other methods, which will not be listed here. In one embodiment, the discharge component 104 is fixed to the housing body 211 by four screws.

[0062] In some exemplary embodiments, the plasma generating module 10 also includes an indicator light disposed within the housing 102. Figures 3 to 7 (Not shown in the image).

[0063] The indicator light can be used to indicate the status of the plasma generating module 10, such as working status, standby status, and off status. The housing 102 may be provided with a light-transmitting part adapted to the indicator light so that the light from the indicator light can be transmitted.

[0064] In some exemplary embodiments, the indicator light is snapped onto the base 212. The indicator light can be, but is not limited to, a light strip. The base 212 may be provided with structures such as a limiting groove 2123 and a limiting flange 2125 to fix the light strip, such as... Figure 6 and Figure 7 As shown. The limiting groove 2123 can be formed by multiple limiting ribs 2124. The light strip can be locked in the limiting groove 2123 and pressed down by the limiting fold 2125 to prevent the light strip from coming out of the limiting groove 2123.

[0065] like Figure 6 As shown, the base 212 has three wiring ports 2122, two of which are used for wiring the discharge assembly 104, and the other is used for wiring the indicator light. The discharge assembly 104 may have two electrical connecting pieces 1042, which are configured to correspond one-to-one with the two wiring ports 2122. The two electrical connecting pieces 1042 can be physically and electrically connected to the wire body through welding, fasteners, or other methods.

[0066] In some exemplary embodiments, the housing 102 is provided with a first mounting groove 123, a first wiring groove 124, a vent 1122 corresponding to and communicating with the first mounting groove 123, and a cable passage 13 corresponding to and communicating with the first wiring groove 124. The first mounting groove 123 and the first wiring groove 124 are located inside the housing 102, and the vent 1122 and the cable passage 13 communicate with the external space.

[0067] The discharge assembly 104 is installed in the first mounting slot 123 so that plasma can be discharged from the outer casing 102 through the vent 1122. The first wiring slot 124 and the wire passage 13 allow the wires connecting to the discharge assembly 104 to pass through, so that the discharge assembly 104 can be electrically connected to an external power source through the wires. The external power source and the air conditioner power source can be independent of each other (i.e., the external power source supplies power to the discharge assembly 104, and the air conditioner power source supplies power to other electrical components of the air conditioner), or they can be integrated into one unit (i.e., the air conditioner power source supplies power to both other electrical components of the air conditioner and the discharge assembly 104).

[0068] During production, the discharge assembly 104 can be installed in the first mounting slot 123 of the housing 102, the wire is passed through the first wiring slot 124 and the wire outlet 13, and the discharge assembly 104 is connected to an external power supply so that the power supply can supply power to the discharge assembly 104. The plasma generating module 10 is installed at the air inlet 202 of the air conditioner (e.g., Figure 1 As shown, the vent 1122 of the plasma generating module 10 is connected to the air duct of the air conditioner. In this way, when the discharge component 104 is energized, it can discharge to generate plasma. The plasma is discharged from the outer shell 102 of the plasma generating module 10 through the vent 1122 and enters the air duct of the air conditioner, and is discharged into the indoor space through the air duct of the air conditioner.

[0069] Furthermore, the first mounting slot 123 can provide positioning and limiting for the installation of the discharge assembly 104, which helps improve the installation efficiency of the discharge assembly 104. The first wiring slot 124 can provide positioning and guiding for the wires, which helps reduce the difficulty of wiring, facilitates smooth connection between the discharge assembly 104 and the external power supply, and helps avoid messy wiring.

[0070] Plasma can be discharged along with the airflow in the duct. Alternatively, it can spontaneously diffuse outwards under the influence of negative pressure or concentration difference generated by the airflow.

[0071] In some exemplary embodiments, please refer to Figure 8 and Figure 9 ,as well as Figure 10 and Figure 11 As shown, the housing 102 includes a detachably connected mounting base 12 and a cover 11. The cover 11 covers the mounting base 12 and encloses the mounting base 12 to form a cable passage 13. A first mounting groove 123 and a first cable routing groove 124 are provided on the mounting base 12, and a vent 1122 is provided on the cover 11.

[0072] During production, the mounting base 12 and the cover 11 can be disassembled, and the discharge assembly 104 can be placed into the first mounting slot 123 and fixed (e.g., Figure 9 and Figure 11 (As shown), then connect the discharge assembly 104 to the external power supply via a cable, and then cover it with the cover 11. This facilitates both the installation of the discharge assembly 104 and the connection of the cable, reducing assembly difficulty. During later inspection and maintenance, the cover 11 and the mounting base 12 can also be disassembled for easy repair and replacement of the discharge assembly 104.

[0073] In some exemplary embodiments, the cover 11 includes a cover body 111 and a cover shell 112 connected to the cover body 111, such as... Figure 8 and Figure 10 As shown.

[0074] The cover body 111 is mounted on the mounting base 12, and together with the mounting base 12, forms a cable passage 13. The cover body 111 covers a portion of the first cable routing groove 124 and the first mounting groove 123. The cover body 111 has a clearance opening 1115 that corresponds to and communicates with the first mounting groove 123, such as... Figure 12 and Figure 13 As shown. The cover 112 covers the clearance opening 1115 and has a vent 1122 so that the vent 1122 is connected to the first mounting groove 123.

[0075] This design protects the discharge assembly 104 and the wiring harness, preventing adverse effects from airflow at the inlet 202. The clearance opening 1115 ensures that the plasma generated by the discharge assembly 104 can reach the vent 1122 via the clearance opening 1115 and then be discharged through the vent 1122. Furthermore, the cover 112 increases the distance between the vent 1122 and the discharge assembly 104, helping to prevent direct airflow from negatively impacting the performance of the discharge assembly 104.

[0076] Furthermore, when the plasma generating module 10 is installed on the housing 200 or bracket of the air conditioner, only the cover 112 needs to be inserted into the air duct of the air conditioner. This ensures that the plasma can enter the air duct and be discharged, and also helps to prevent airflow, dust and other impurities in the air duct from contacting the discharge component 104, thus improving the reliability of the discharge component 104.

[0077] The cover 112 can be a hollow shell structure, with the hollowed-out parts serving as vents 1122, such as... Figure 8 , Figure 10 and Figure 14 As shown, this increases the airflow area, facilitating rapid plasma diffusion. The cover 112 may include a windward and leeward surface spaced apart, and a top surface located between the windward and leeward surfaces. The windward, leeward, and top surfaces may all have vents 1122, such as... Figure 8 , Figure 10 and Figure 14 As shown. Such good ventilation helps to prevent condensation from forming in the plasma generator.

[0078] In some exemplary embodiments, such as Figure 8 and Figure 12 As shown, the cover body 111 includes a cover plate 1111 and a first side plate 1112 connected to the cover plate 1111, with an avoidance opening 1115 provided on the cover plate 1111. In this way, there is a certain gap between the mounting base 12 and the avoidance opening 1115, so that the discharge assembly 104 has a suitable discharge space, which is beneficial to improving the discharge efficiency.

[0079] The first side plate 1112 is provided with a wire passage notch 1114, which together with the end of the first wiring groove 124 forms a wire passage opening 13. In this way, the wire passage opening 13 has a relatively large wire passage area, which makes it easier for the wire to be tilted, bent or otherwise manipulated outside the outer shell 102 as needed, so as to reasonably arrange the relative positions of the plasma generating module 10 and the external power supply.

[0080] In some exemplary embodiments, such as Figure 8 , Figure 9 , Figure 11 As shown, the mounting base 12 includes a base plate 121 and a second side plate 122 connected to the base plate 121. The second side plate 122 and the base plate 121 together form a first mounting groove 123, and a first wiring groove 124 is provided on the base plate 121. Thus, the structure of the mounting base 12 is relatively simple and easy to process and form.

[0081] In some exemplary embodiments, such as Figure 8 and Figure 10 As shown, the first side plate 1112 and the second side plate 122 are staggered. The first side plate 1112 abuts against the bottom plate 121, and the second side plate 122 abuts against the cover plate 1111. This helps to reduce the overall thickness of the outer shell 102, thereby reducing the volume of the plasma generating module 10 and the space required for assembly.

[0082] In some exemplary embodiments, such as Figure 8 As shown, the cover 112 and the cover body 111 are an integral structure, which can reduce the number of parts included in the outer shell 102, thereby simplifying the assembly process.

[0083] In some exemplary embodiments, please refer to Figure 10 , Figure 12 , Figure 13 and Figure 14 As shown, the cover shell 112 and the cover body 111 are separate assembly structures, which can simplify the structure of each component of the outer shell 102 and facilitate the individual processing and molding of each component.

[0084] In some exemplary embodiments, one of the cover shell 112 and the cover body 111 is provided with a first latch 1121 (e.g., Figure 14 As shown), the other has a first card slot 1118 (as shown). Figure 12 As shown), the first buckle 1121 engages with the first slot 1118 to connect the cover 112 with the cover body 111. Figure 10 As shown.

[0085] The snap-fit ​​assembly method has a simple structure and is relatively convenient to assemble, which helps to improve assembly efficiency. Among them, there can be multiple first snaps 1121, which can be divided into two groups. The two groups of first snaps 1121 can be spaced apart along the width direction of the outer shell 102, so that the cover shell 112 and the cover body 111 are reliably connected and the force is relatively balanced.

[0086] In other embodiments, the cover 112 and the cover body 111 may also be connected by fasteners (such as screws) or by other means.

[0087] In some exemplary embodiments, one of the cover shell 112 and the cover body 111 is provided with a first positioning protrusion 1117 (e.g., Figure 12 and Figure 13 As shown), the other is provided with a first positioning groove 1124 (as shown). Figure 14 (As shown). The first positioning protrusion 1117 is embedded in the first positioning groove 1124 to position the relative position of the cover shell 112 and the cover body 111, as shown. Figure 10 As shown.

[0088] This can increase the assembly speed of the cover shell 112 and the cover body 111, which is beneficial to improving the assembly efficiency of the plasma generating module 10. As for the shape of the first positioning protrusion 1117, it is not limited and can include, but is not limited to: columnar, plate-shaped, block-shaped, strip-shaped, etc.

[0089] In some exemplary embodiments, one of the cover 11 and the mounting base 12 is provided with a second latch 1113 (e.g., Figure 12 and Figure 13 As shown), the other has a second card slot 128 (as shown). Figure 9 , Figure 11 As shown), the second buckle 1113 engages with the second slot 128 to connect the cover 11 with the mounting base 12. Figure 8 and Figure 10 As shown.

[0090] The snap-fit ​​assembly method is simple in structure and convenient to assemble, which helps to improve assembly efficiency. Multiple second snap-fits 1113 can be used, and these can be divided into two groups. The two groups of second snap-fits 1113 can be spaced apart along the width of the outer shell 102, ensuring a reliable connection between the cover 11 and the mounting base 12 and relatively balanced force distribution. For a cover 11 comprising a cover body 111 and a cover shell 112, the second snap-fit ​​1113 or the second slot 128 can be provided on the cover body 111. When the cover body 111 comprises a cover plate 1111 and a first side plate 1112, the second snap-fit ​​1113 or the second slot 128 can be provided on the cover plate 1111.

[0091] In other embodiments, the cover 112 and the cover plate 1111 may also be connected by fasteners (such as screws) or by other means.

[0092] In some exemplary embodiments, one of the cover 11 and the mounting base 12 is provided with a second positioning protrusion 1119 (e.g., Figure 12 and Figure 13 As shown), the other is provided with a second positioning groove 127 (as shown). Figure 11 As shown), the second positioning protrusion 1119 is embedded in the second positioning groove 127 to position the relative position of the cover 11 and the mounting base 12, as shown. Figure 10 As shown.

[0093] This can increase the assembly speed of the cover 11 and the mounting base 12, which is beneficial to improving the assembly efficiency of the plasma generating module 10. The shape of the second positioning protrusion 1119 is not limited and can include, but is not limited to, columnar, plate-shaped, block-shaped, strip-shaped, etc. For a cover 11 that includes a cover body 111 and a cover shell 112, the second positioning protrusion 1119 or the second positioning groove 127 can be provided on the cover body 111. When the cover body 111 includes a cover plate 1111 and a first side plate 1112, the second positioning protrusion 1119 or the second positioning groove 127 can be provided on the cover plate 1111.

[0094] In some exemplary embodiments, the housing 102 is provided with a third latch 1123 (e.g. Figure 8 , Figure 10 and Figure 14 As shown), the third clip 1123 is used to clip the plasma generating module 10 onto the housing 200 of the air conditioner (e.g., the grille of the air inlet 202) or onto the bracket at the air inlet 202.

[0095] The snap-fit ​​assembly method is simple in structure and convenient to assemble, which helps to improve the assembly efficiency between the plasma generating module 10 and the air conditioner housing 200 or bracket. Multiple third snap-fits 1123 can be used, and these can be divided into two groups. The two groups of third snap-fits 1123 can be spaced apart along the length of the housing 102, ensuring a reliable connection between the housing 102 and the air conditioner housing 200 or bracket, and relatively balanced force distribution. For a housing 102 comprising a cover 11 and a mounting base 12, the third snap-fit ​​1123 can be located on the cover 11. For a cover 11 comprising a cover body 111 and a cover shell 112, the third snap-fit ​​1123 can be located on the cover shell 112.

[0096] In other embodiments, the plasma generating module 10 may also be connected by fasteners (such as screws) or other means.

[0097] In some exemplary embodiments, the first wiring channel 124 includes a first sub-channel 1241 and a second sub-channel 1242, such as Figure 9 and Figure 11 As shown, the first sub-slot 1241 and the second sub-slot 1242 are spaced apart on both sides of the first mounting slot 123 along the length of the outer casing 102.

[0098] The cable port 13 includes a first sub-port and a second sub-port. The first sub-port is connected to the end of the first sub-slot 1241, and the second sub-port is connected to the end of the second sub-slot 1242.

[0099] In this way, the positive and negative terminals of the discharge assembly 104 can be wired separately from different directions, which helps to avoid incorrect wiring.

[0100] In some exemplary embodiments, such as Figure 11 As shown, the plasma generating module 10 also includes an indicator light 3, installed inside the housing 102, configured to display the status of the plasma generating module. The housing 102 also has a light-transmitting portion 1116 (e.g., Figure 12 and Figure 13 As shown), the light-transmitting part 1116 is correspondingly provided with the indicator light 3 so that the light emitted by the indicator light 3 can be transmitted through the light-transmitting part 1116.

[0101] This allows for visualization of the status of the plasma generating module 10, enabling users to clearly understand its status and improving the user experience.

[0102] For example: when indicator light 3 is on, it indicates that the plasma generating module 10 is working; when indicator light 3 is off, it indicates that the plasma generating module 10 has stopped working. Or, when indicator light 3 is green, it indicates that the plasma generating device is normal; when indicator light 3 is red, it indicates that the plasma generating module 10 is malfunctioning.

[0103] Of course, the light signals emitted by indicator light 3 are not limited to those mentioned above; they can also include changes in brightness, changes in flashing patterns, etc. The states indicated by indicator light 3 are also not limited to those mentioned above; they can also include changes in operating intensity, changes in operating duration, etc.

[0104] The specific form of indicator light 3 is not limited, and it can be, but is not limited to, LED beads, LED strips, LED bars, etc. The structure of the light-transmitting part 1116 is also not limited, and it can be, but is not limited to, light-transmitting holes, light-transmitting slits, light-transmitting windows, etc.

[0105] In one embodiment, indicator light 3 is a light strip, and the light-transmitting part 1116 is a light-transmitting slit corresponding to the light strip, such as... Figure 12 and Figure 13 As shown. In this way, light can only pass through the slit, preventing the light from becoming too intense.

[0106] In some exemplary embodiments, a second mounting groove 125 is also provided within the housing 102, such as... Figure 11 As shown, the indicator light 3 is fixed in the second mounting slot 125, which helps to improve the positional reliability of the indicator light 3. The first wiring slot 124 is also configured to allow the wires of the indicator light 3 to pass through, so as to facilitate the wiring of the indicator light 3.

[0107] In some exemplary embodiments, such as Figure 11 As shown, the first mounting groove 123 and the second mounting groove 125 are arranged along the length of the housing 102. The housing 102 is also provided with a second wiring groove 126, which communicates with the first wiring groove 124, and the second wiring groove 126 and the second mounting groove 125 are arranged along the width of the housing 102. This allows the portion of the wires of the discharge assembly 104 located inside the housing 102 to be confined within the wiring grooves as much as possible, avoiding messy wiring.

[0108] In some exemplary embodiments, the power conversion module 400 is configured to provide alternating current to the plasma generating module 100, wherein the peak voltage of the alternating current may be in the range of, but is not limited to, 2000V to 10000V (e.g., 2000V, 4000V, 6000V, 8000V, 10000V, etc.), and the frequency of the alternating current may be in the range of, but is not limited to, 5kHz to 50kHz (e.g., 5kHz, 10kHz, 20kHz, 30kHz, 40kHz, 50kHz, etc.).

[0109] Tests have shown that air conditioners using the above-mentioned design have a good air purification effect.

[0110] In some exemplary embodiments, the distance between the plasma generating module 100 and the catalyst module 300 is in the range of 0.01cm to 5cm, such as 0.01cm, 0.1cm, 0.5cm, 1cm, 2cm, 3cm, 4cm, 5cm, etc.

[0111] Thus, there is a certain space between the plasma generation module 100 and the catalyst module 300, which is used for the mixing and interaction of high-energy plasma with bacteria, viruses, allergens, and gaseous pollutants.

[0112] Of course, the spacing between the plasma generation module 100 and the catalyst module 300 is not limited to the range described above.

[0113] In some exemplary embodiments, the catalyst module 300 includes a substrate with air passages and a catalyst supported on the substrate. The catalyst can be an adsorption catalyst, i.e., an adsorption catalyst. Alternatively, the catalyst can be a catalyst without adsorption properties.

[0114] The catalyst includes at least one of single metal oxides, perovskite polymetallic oxides, and metal catalysts.

[0115] Among them, the single metal oxides include at least one of the following: manganese oxide (MnOx), cerium oxide (CeOx), etc.; the perovskite polymetallic oxides include at least one of the following: LaFeO3, LaCoO3, and LaMnO3; and the metal catalysts include at least one of the following: Pd, Pt, Co, Cu, etc.

[0116] The substrate can be, but is not limited to, a honeycomb structure, which facilitates the adsorption of gaseous pollutants such as formaldehyde and benzene compounds onto the catalyst module 300. High-energy active particles and highly oxidizing ozone can act on the catalyst to decompose gaseous pollutants such as formaldehyde and benzene compounds until these pollutants are decomposed into carbon dioxide.

[0117] In one embodiment, the air conditioner is a wall-mounted air conditioner. The wall-mounted air conditioner is placed in a 30-cubic-meter test chamber for sterilization function testing.

[0118] The fan rotates at 600 rpm, drawing indoor air through its rotation; the airflow is set to 700 m³ / h. 3 / h. The power conversion module 400 starts up, supplying power to the plasma generation module 100 with AC power at a peak voltage of 4000V and a frequency of 30kHz. After the plasma generation module 100 starts up, it breaks down the air, simultaneously generating high-energy active particles and highly oxidizing ozone to kill Staphylococcus aureus in the air. The distance between the plasma generation module 100 and the catalyst module 300 is set at 1.5cm to create a mixing zone for the high-energy plasma and Staphylococcus aureus.

[0119] Test results: The sterilization rate reached 99.9% after 2 hours.

[0120] In one embodiment, the air conditioner is a wall-mounted air conditioner. The wall-mounted air conditioner was placed in a 30-cubic-meter test chamber for mold-killing function testing.

[0121] The fan rotates at 600 rpm, drawing indoor air through its rotation; the airflow is set to 800 m³ / h. 3 / h. The power conversion module 400 starts up, supplying power to the plasma generation module 100. The power is AC, with a peak voltage of 6500V and a frequency of 20KHz.

[0122] After the plasma generating module 100 is activated, it breaks down the air and generates high-energy active particles to kill Aspergillus niger in the air. The distance between the plasma generating module 100 and the catalyst module 300 is set at 1 cm to create a mixing zone for the high-energy plasma and Aspergillus niger.

[0123] Test results: The sterilization rate reached 99.56% after 2 hours.

[0124] In one embodiment, the air conditioner is a wall-mounted air conditioner. The wall-mounted air conditioner was placed in a 30-cubic-meter test chamber for formaldehyde and toluene removal function tests.

[0125] The fan rotates at 600 rpm, drawing indoor air through its rotation; the airflow is set to 780 m³ / h. 3 / h. The power conversion module 400 starts up, supplying power to the plasma generation module 100. The power is AC, with a peak voltage of 5500V and a frequency of 25KHz.

[0126] After the plasma generation module is activated, it breaks down the air, producing blue-violet light and high-energy active particles.

[0127] The distance between the plasma generating module 100 and the catalyst module 300 is set at 0.5 cm to create a mixing zone for high-energy plasma and formaldehyde. After mixing, the high-energy plasma and formaldehyde are adsorbed onto the catalyst module 300, which uses a MnOx-CeOx catalyst.

[0128] Test results: The CADR (Clear Air Delivery Rate) value for formaldehyde is 144m³. 3 / h, the CADR value of toluene is 212 m 3 / h, the carbon dioxide selectivity can reach about 80%.

[0129] Among these, a higher CADR value indicates that the air purifier can output a larger volume of clean air per unit time, resulting in higher purification efficiency. Carbon dioxide selectivity is commonly used as an experimental parameter for the adsorption performance of adsorbent materials. It is generally expressed as the ratio of the adsorption capacity of the target pollutant to that of CO2 under the same conditions. This indicator measures the "specificity" of the material for harmful gaseous pollutants (such as formaldehyde and benzene), that is, whether it can preferentially and effectively remove harmful gases rather than common gases like carbon dioxide in a gas mixture (air), thereby improving the effectiveness and efficiency of the purification device. High selectivity means that in actual use, it is highly efficient in purifying the target pollutant without consuming purification capacity on non-target gases (such as carbon dioxide).

[0130] In summary, the air conditioner provided in this application has the following beneficial effects: it can achieve multi-functional integration of sterilization, virus killing, allergen removal, and removal of gaseous pollutants such as formaldehyde and benzene series compounds; compared with the traditional negative ion physical sedimentation scheme, this scheme has higher sterilization and virus killing efficiency and can remove allergens; it can directly decompose formaldehyde and benzene series compounds into carbon dioxide, rather than the traditional direct adsorption.
