[0003] However, after long-term use, a large number of bacteria, viruses, etc. are likely to breed inside the indoor unit of the air conditioner. Especially on the surface of the evaporator, since water vapor in the air will condense on the surface of the evaporator, the humid environment is more conducive to the growth of bacteria. In this way, when air flows through the inside of the indoor unit of the air conditioner, bacteria, viruses, etc. will be transported into the room, thereby causing a decline in the indoor air quality and seriously endangering people's health when severe.

The embodiments described below by referring to the accompanying drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0058] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.

[0059] The air conditioner indoor unit 1000 of the embodiments of the present invention will be described below with reference to the accompanying drawings of the specification.

[0060] Combined withFigure 1 , Figure 2 and Figure 3 As shown in Figure 1 , Figure 2 and Figure 3 , an air conditioner indoor unit 1000 according to an embodiment of the present invention includes a housing assembly 100, an evaporator 200, a fan 300 and a sterilization device 400.

[0061] Among them, as shown in combination with Figure 1 and Figure 3 , the housing assembly 100 has an air inlet 110, an air outlet 120 and an air duct 130, and the air duct 130 communicates the air inlet 110 and the air outlet 120. In this way, external air can enter the air duct 130 of the housing assembly 100 through the air inlet 110 and flow toward the air outlet 120 through the air duct 130, so as to convey the air to the room through the air outlet 120, achieve the purpose of adjusting the indoor air temperature, improve the indoor comfort, and ensure the working performance of the air conditioner indoor unit 1000.

[0062] As Figure 3 shown, both the evaporator 200 and the fan 300 are arranged in the air duct 130, and the fan 300 is located between the evaporator 200 and the air outlet 120 in the air flow direction. That is to say, both the evaporator 200 and the fan 300 are arranged in the air duct 130, and when air flows along the air duct 130, the air passes through the evaporator 200, the fan 300 and the air outlet 120 in sequence.

[0063] Among them, the fan 300 is mainly used to drive the air flow to ensure that the air can effectively flow through the evaporator 200 and ensure that the air can flow toward the air outlet 120, so as to convey the air to the room through the air outlet 120. When the air flows through the evaporator 200, the evaporator 200 is mainly used to exchange heat with the air flowing through it to adjust the air temperature, so that the air conveyed to the room through the air outlet 120 can effectively adjust the indoor temperature and ensure the working performance of the air conditioner indoor unit 1000.

[0064] It should be noted that the evaporator 200 and the fan 300 of the present application are both well-known prior arts to those skilled in the art and will not be elaborated here.

[0065] Combined with Figure 1 , Figure 2 and Figure 3 shown, the sterilization device 400 includes a negative ion sterilization component 410, a pulsed light sterilization component 420 and a power supply box 430. The power supply box 430 is used to supply power to the negative ion sterilization component 410 and the pulsed light sterilization component 420 respectively. The negative ion sterilization component 410, the pulsed light sterilization component 420 and the power supply box 430 are independently arranged on the housing assembly 100.

[0066] ​​​​Among them, by setting the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430, and setting the power supply box 430 to be able to supply power to the negative ion sterilization component 410 and the pulsed light sterilization component 420, so that the negative ion sterilization component 410 and the pulsed light sterilization component 420 can effectively carry out the sterilization work.

[0067] Among them, when the power supply box 430 is used to supply power to the negative ion sterilization component 410, the negative ion sterilization component 410 can produce negative ions, which can combine with microorganisms such as dust, bacteria, and viruses in the air, changing their structures, thereby achieving the purpose of sterilization and purifying the air; when the power supply box 430 is used to supply power to the pulsed light sterilization component 420, the pulsed light sterilization component 420 can emit sterilizing light rays, such as ultraviolet light rays, infrared light rays, etc., so as to remove bacteria, viruses, etc. in the air, thereby achieving the removal of bacteria, viruses, etc. in the air conditioner indoor unit 1000 and ensuring the cleanliness of the air discharged from the air conditioner indoor unit 1000.

[0068] In summary, the air conditioner indoor unit 1000 of the present application can emit sterilizing light rays and release ions capable of sterilizing, achieving the purpose of double-stage purification and sterilization, so as to improve the sterilization and purification efficiency of the air conditioner indoor unit 1000, thereby improving the cleanliness of the air discharged from the air conditioner indoor unit 1000.

[0069] At the same time, by independently arranging the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430 in the casing assembly 100, the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430 can form three separate parts. In this way, when processing the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430, the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430 can be processed separately, so as to reduce the processing difficulty of the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430. And during assembly, the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430 can be assembled separately, achieving the reduction of the assembly difficulty of the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430 and improving the assembly efficiency. At the same time, during the use and maintenance process, the structural parts that need to be maintained can also be disassembled separately, without the need to remove the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430 as a whole, achieving the reduction of the maintenance difficulty of the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430.

[0070] That is to say, in this application, the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430 are independently arranged in the housing component 100. On the one hand, it can reduce the manufacturing difficulty of the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430. On the other hand, it can improve the assembly efficiency of the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430, that is, improve the assembly efficiency of the air conditioner indoor unit 1000. On the third hand, it can also reduce the maintenance difficulty of the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430.

[0071] It is also worth noting that in this application, the power supply box 430 is used to supply power to the negative ion sterilization component 410 and the pulsed light sterilization component 420 respectively, so that the negative ion sterilization component 410 and the pulsed light sterilization component 420 can share one power supply box 430. In this way, the number of power supply boxes 430 used can be reduced, thereby simplifying the structure of the air conditioner indoor unit 1000, reducing the assembly difficulty of the air conditioner indoor unit 1000, reducing the manufacturing cost of the air conditioner indoor unit 1000, and saving the occupied space of the power supply box 430, which is beneficial to the compact setting of the air conditioner indoor unit 1000.

[0072] As can be seen from the above structure, for the air conditioner indoor unit 1000 according to the embodiment of the present invention, by arranging the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430, the air conditioner indoor unit 1000 can emit sterilizing light and release ions capable of sterilizing, achieving the purpose of dual-stage purification and sterilization, improving the sterilization and purification efficiency of the air conditioner indoor unit 1000, and thus improving the cleanliness of the air discharged from the air conditioner indoor unit 1000.

[0073] At the same time, the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430 are independently arranged in the housing component 100, so that the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430 are independent of each other, thereby reducing the manufacturing difficulty of the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430, improving the assembly efficiency of the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430, and reducing the maintenance difficulty of the negative ion sterilization component 410, the pulsed light sterilization component 420, and the power supply box 430, thereby reducing the maintenance difficulty of the air conditioner indoor unit 1000, improving the maintenance efficiency, and thus enhancing the user experience.

[0074] It can be understood that, compared with the prior art, the present application is provided with a negative ion sterilization component 410, a pulsed light sterilization component 420 and a power supply box 430, and the negative ion sterilization component 410, the pulsed light sterilization component 420 and the power supply box 430 are independently arranged in the casing component 100. In this way, while the air conditioner indoor unit 1000 can achieve dual-stage purification and sterilization, the maintenance difficulty of the air conditioner indoor unit 1000 can be reduced, and it is beneficial to improve the maintenance efficiency of the air conditioner indoor unit 1000.

[0075] In some embodiments, in combination with Figure 5 and Figure 6 As shown, the power supply box 430 includes: a box body 431, a first circuit board 432 and a second circuit board 433. The first circuit board 432 and the second circuit board 433 are both arranged in the box body 431. The first circuit board 432 is connected to the negative ion sterilization component 410 through a first wire, and the second circuit board 433 is connected to the pulsed light sterilization component 420 through a second wire. Thus, the power supply box 430 can be simultaneously connected to the negative ion sterilization component 410 and the pulsed light sterilization component 420, achieving the purpose of using the power supply box 430 to supply power to the negative ion sterilization component 410 and the pulsed light sterilization component 420 respectively, so as to ensure the working performance of the negative ion sterilization component 410 and the pulsed light sterilization component 420. And through the above arrangement, the negative ion sterilization component 410 and the pulsed light sterilization component 420 can also be controlled by separate circuit boards respectively, so as to reduce the control difficulty of the negative ion sterilization component 410 and the pulsed light sterilization component 420. In this way, when power cannot be supplied to the negative ion sterilization component 410 or the pulsed light sterilization component 420 subsequently, only one of the circuit boards needs to be checked, reducing the maintenance difficulty.

[0076] At the same time, through the above arrangement, the purpose of using one power supply box 430 to control the negative ion sterilization component 410 and the pulsed light sterilization component 420 simultaneously can also be achieved, so as to reduce the number of power supply boxes 430 used, thereby simplifying the structure of the air conditioner indoor unit 1000, reducing the assembly difficulty of the air conditioner indoor unit 1000, and reducing the manufacturing cost of the air conditioner indoor unit 1000.

[0077] In addition, by arranging both the first circuit board 432 and the second circuit board 433 in the box body 431, the box body 431 can also be used to protect and support the first circuit board 432 and the second circuit board 433, so as to improve the use safety of the first circuit board 432 and the second circuit board 433, extend the service life of the first circuit board 432 and the second circuit board 433, and improve the position stability of the first circuit board 432 and the second circuit board 433, thereby ensuring the working performance of the power supply box 430.

[0078] In some embodiments, in combination with Figure 5 and Figure 6As shown, a partition rib 4311 is provided inside the box body 431. The partition rib 4311 divides the inner cavity of the box body 431 into a first chamber 4312 and a second chamber 4313. The first circuit board 432 is disposed in the first chamber 4312, and the second circuit board 433 is disposed in the second chamber 4313. In this way, while realizing that both the first circuit board 432 and the second circuit board 433 are disposed inside the box body 431, the first circuit board 432 and the second circuit board 433 can be separated from each other, avoiding interference between the first circuit board 432 and the second circuit board 433, so as to reduce the installation difficulty of the first circuit board 432 and the second circuit board 433, and ensure the working performance of the first circuit board 432 and the second circuit board 433.

[0079] In some embodiments, in combination with Figure 5 and Figure 6 As shown, the shape and size of the first chamber 4312 are adapted to the first circuit board 432, and the shape and size of the second chamber 4313 are adapted to the second circuit board 433. In this way, while ensuring that the first circuit board 432 can be disposed in the first chamber 4312 and the second circuit board 433 can be disposed in the second chamber 4313, the installation difficulty of the first circuit board 432 and the second circuit board 433 can be further reduced. Additionally, the first chamber 4312 can be utilized to support the first circuit board 432 and the second chamber 4313 can be used to support the second circuit board 433, so as to further improve the position stability of the first circuit board 432 and the second circuit board 433, and ensure the working performance of the first circuit board 432 and the second circuit board 433.

[0080] In some embodiments, sealants are respectively filled in the first chamber 4312 and the second chamber 4313 to respectively seal the first circuit board 432 and the second circuit board 433. The height of the sealant in the first chamber 4312 is not equal to the height of the sealant in the second chamber 4313. Among them, by filling the sealant to seal the first circuit board 432 and the second circuit board 433, while protecting the first circuit board 432 and the second circuit board 433, it can also serve the purpose of fixing the first circuit board 432 and the second circuit board 433, so as to extend the service life of the first circuit board 432 and the second circuit board 433, and prevent the first circuit board 432 and the second circuit board 433 from shaking inside the box body 431.

[0081] In addition, by setting the height of the sealant in the first chamber 4312 to be not equal to the height of the sealant in the second chamber 4313, it is also convenient for users to distinguish the first chamber 4312 and the second chamber 4313, so as to reduce the maintenance difficulty of the subsequent first circuit board 432 and the second circuit board 433.

[0082] In some embodiments, the height of the potting glue in the first chamber 4312 is greater than the height of the potting glue in the second chamber 4313, so that the height of the potting glue in the first chamber 4312 is not equal to the height of the potting glue in the second chamber 4313, thereby facilitating the user to distinguish the first chamber 4312 from the second chamber 4313, that is, ensuring that when the first circuit board 432 and the second circuit board 433 are potted and sealed, the user can quickly and accurately locate the installation positions of the first circuit board 432 and the second circuit board 433.

[0083] In other embodiments, the height of the potting glue in the first chamber 4312 is less than the height of the potting glue in the second chamber 4313, so that the height of the potting glue in the first chamber 4312 is not equal to the height of the potting glue in the second chamber 4313.

[0084] It should be noted that since the chamber size of the first chamber 4312 is larger than that of the second chamber 4313, by setting the height of the potting glue in the first chamber 4312 to be less than the height of the potting glue in the second chamber 4313, the amount of potting glue in the first chamber 4312 can also be reduced, thereby reducing the potting glue cost of the first chamber 4312 and being beneficial to reducing the weight of the power supply box 430 and lowering the installation difficulty of the power supply box 430.

[0085] In some embodiments, in order to further ensure that the user can quickly and accurately locate the installation positions of the first circuit board 432 and the second circuit board 433, after the potting of the first chamber 4312 and the second chamber 4313 is completed, words, graphics, etc. can be printed on the potting surface to further distinguish the first circuit board 432 from the second circuit board 433.

[0086] In some embodiments, in combination with Figure 5 and Figure 6 As shown, the box body 431 has a first wire outlet 4314 and a second wire outlet 4315. The power supply box 430 further includes: a first lead wire and a second lead wire. One end of the first lead wire is connected to the first circuit board 432 and the other end passes through the first wire outlet 4314 to be connected to the first wire, and one end of the second lead wire is connected to the second circuit board 433 and the other end passes through the second wire outlet 4315 to be connected to the second wire. Thus, the electrical connection between the first circuit board 432 and the negative ion sterilization component 410 is realized and the electrical connection between the second circuit board 433 and the pulsed light sterilization component 420 is realized, facilitating the use of the power supply box 430 to supply power to the negative ion sterilization component 410 and the pulsed light sterilization component 420 respectively, ensuring the working performance of the negative ion sterilization component 410 and the pulsed light sterilization component 420, and reducing the connection difficulty between the power supply box 430 and the negative ion sterilization component 410 and the pulsed light sterilization component 420 respectively.

[0087] In some embodiments, as shown in Figure 5 andFigure 6 As shown, the power supply box 430 further includes a protective housing 434, which is wrapped around the outside of the box body 431 and exposes the first wire outlet 4314 and the second wire outlet 4315. In this way, while preventing the protective housing 434 from hindering the connection between the first lead wire and the first wire and the connection between the second lead wire and the second wire, the protective housing 434 can also be used to protect the box body 431, so as to extend the service life of the box body 431 and thus reduce the use cost of the power supply box 430.

[0088] In some embodiments, the protective housing 434 is a metal housing. On the one hand, the metal housing can endow the protective housing 434 with certain structural strength, so as to facilitate the use of the protective housing 434 to protect the box body 431 and improve the protection performance of the protective housing 434; on the other hand, it can also prevent the first circuit board 432 and the second circuit board 433 from bursting and splashing the potting glue onto other components after bursting, thus avoiding large-area fire and safety hazard events and improving the use performance of the power supply box 430.

[0089] In some embodiments, the protective housing 434 is composed of two opposite parts, and the power supply box 430 is arranged between the two opposite parts of the protective housing 434 to reduce the assembly difficulty between the power supply box 430 and the protective housing 434, so as to facilitate the use of the protective housing 434 to protect the box body 431.

[0090] In some embodiments, in combination Figure 5 and Figure 6 As shown, connection ears 4342 are provided on both of the two opposite parts of the protective housing 434, and the two opposite parts of the protective housing 434 are fixedly connected through fastening connectors passing through the connection ears 4342; and / or, a connection protrusion 4341 is provided on one of the protective housings 434, and a limiting hole matching with the connection protrusion 4341 is provided on the other protective housing 434. Here, it means that connection ears 4342 are provided on both of the two opposite parts of the protective housing 434, and the two opposite parts of the protective housing 434 are fixedly connected through fastening connectors passing through the connection ears 4342; or, among the two opposite parts of the protective housing 434, a connection protrusion 4341 is provided on one of the protective housings 434, and a limiting hole matching with the connection protrusion 4341 is provided on the other protective housing 434, and the connection protrusion 4341 is limited and fitted in the limiting hole to realize the fixed connection of the two opposite parts of the protective housing 434; or, connection ears 4342 are provided on both of the two opposite parts of the protective housing 434, and the two opposite parts of the protective housing 434 are fixedly connected through fastening connectors passing through the connection ears 4342 and a connection protrusion 4341 is provided on one of the protective housings 434, and a limiting hole matching with the connection protrusion 4341 is provided on the other protective housing 434. In this way, while realizing the fixed connection of the two opposite parts of the protective housing 434, the structural strength of the protective housing 434 can also be improved and the forming difficulty of the protective housing 434 can be reduced.

[0091] Among them, the fastening connection member mentioned here can be a fastening bolt or a fastening screw, etc., so as to facilitate the assembly connection of the protective shell 434 by using the fastening connection member.

[0092] In some embodiments, as Figure 3 shown, the negative ion sterilization component 410 is located downstream of the blower 300 in the air flow direction, and the pulsed light sterilization component 420 is located between the evaporator 200 and the blower 300 in the air flow direction. Among them, by arranging the negative ion sterilization component 410 downstream of the blower 300, the negative ion sterilization component 410 can be arranged close to the air outlet 120. In this way, while using the negative ion sterilization component 410 to sterilize the air flowing through it, negative ions can also follow the air to flow through the room, so as to facilitate the use of the negative ion sterilization component 410 to settle PM2.5 and other particulate matters in the room, playing a role in dust removal, thereby improving the indoor air quality and ensuring the user experience.

[0093] At the same time, in the air flow direction, by arranging the pulsed light sterilization component 420 between the evaporator 200 and the blower 300, the pulsed light sterilization component 420 can be arranged close to the evaporator 200. In this way, while using the pulsed light sterilization component 420 to sterilize the air flowing through it, the pulsed light sterilization component 420 can also sterilize the evaporator 200, and then the cleanliness of the air flow after passing through the evaporator 200 can be ensured, realizing the clean air outlet of the air conditioner indoor unit 1000.

[0094] It should be noted that due to the working characteristics of the evaporator 200, bacteria are likely to grow on the surface of the evaporator 200. In this way, when the air flows through the evaporator 200, bacteria, viruses, etc. will be carried into the indoor space, resulting in a decrease in the indoor air quality. Therefore, in this application, the pulsed light sterilization component 420 is arranged between the evaporator 200 and the blower 300 to effectively solve the above problems and improve the working performance of the air conditioner indoor unit 1000.

[0095] It is also worth noting that by arranging the negative ion sterilization component 410 downstream of the blower 300 in the air flow direction and arranging the pulsed light sterilization component 420 between the evaporator 200 and the blower 300 in the air flow direction, the negative ion sterilization component 410 and the pulsed light sterilization component 420 can also be arranged in sequence in the air flow direction, so as to facilitate the cooperation of the negative ion sterilization component 410 and the pulsed light sterilization component 420 to perform multiple sterilization treatments on the air entering the air conditioner indoor unit 1000, so as to improve the cleanliness of the air.

[0096] In some embodiments, in combination with Figure 2 、 Figure 3 and Figure 4As shown, the cabinet assembly 100 includes: a chassis 140 and an evaporator bracket 150. The evaporator bracket 150 is connected to the chassis 140, and one end of the evaporator 200 is connected to the evaporator bracket 150. Among them, by connecting the evaporator bracket 150 to the chassis 140, it is possible to use the chassis 140 to support the evaporator bracket 150 and improve the positional stability of the evaporator bracket 150. After connecting one end of the evaporator 200 to the evaporator bracket 150, the evaporator 200 can be supported by the evaporator bracket 150 to improve the positional stability of the evaporator 200, thereby ensuring the working performance of the evaporator 200. Moreover, the above arrangement can also make the overall structure of the air conditioner indoor unit 1000 stable.

[0097] Optionally, as shown in Figure 7 , Figure 8 and Figure 11 , the power supply box 430 and the pulsed light sterilization component 420 are both arranged on the evaporator bracket 150. In order to use the evaporator bracket 150 to support the power supply box 430 and the pulsed light sterilization component 420 and improve the positional stability of the power supply box 430 and the pulsed light sterilization component 420, thereby ensuring the working performance of the power supply box 430 and the pulsed light sterilization component 420.

[0098] At the same time, by arranging both the power supply box 430 and the pulsed light sterilization component 420 on the evaporator bracket 150, the power supply box 430 can also be arranged close to the pulsed light sterilization component 420, so as to facilitate the electrical connection between the power supply box 430 and the pulsed light sterilization component 420, thereby facilitating the power supply from the power supply box 430 to the pulsed light sterilization component 420 and reducing the connection difficulty between the power supply box 430 and the pulsed light sterilization component 420.

[0099] In addition, the above arrangement can also make the pulsed light sterilization component 420 close to the evaporator 200, so as to facilitate the use of the pulsed light sterilization component 420 to sterilize the evaporator 200, and then the cleanliness of the air flow after passing through the evaporator 200 can be ensured, realizing the clean air output of the air conditioner indoor unit 1000.

[0100] In some embodiments, as shown in Figure 2 , Figure 9 and Figure 10As shown in the figure, the power supply box 430 is arranged on the side of the evaporator bracket 150 facing away from the evaporator 200, and the pulsed light sterilization component 420 is arranged on the side of the evaporator bracket 150 facing the evaporator 200. Among them, by arranging the power supply box 430 on the side of the evaporator bracket 150 facing away from the evaporator 200, while realizing the support of the power supply box 430 by the evaporator bracket 150, the power supply box 430 can be arranged away from the evaporator 200, so as to avoid the interference of the evaporator 200 with the assembly of the power supply box 430, thereby reducing the assembly difficulty of the power supply box 430, that is, reducing the assembly difficulty of the indoor unit 1000 of the air conditioner; by arranging the pulsed light sterilization component 420 on the side of the evaporator bracket 150 facing the evaporator 200; by arranging the pulsed light sterilization component 420 on the side of the evaporator bracket 150 facing the evaporator 200, the pulsed light sterilization component 420 can be arranged directly opposite to the evaporator 200, so as to facilitate the use of the pulsed light sterilization component 420 to sterilize the evaporator 200 and ensure the sterilization effect of the pulsed light sterilization component 420.

[0101] Meanwhile, through the above arrangement, the power supply box 430 and the pulsed light sterilization component 420 can also be arranged on the opposite sides of the evaporator bracket 150 (as shown in Figure 11 and Figure 12 ), so as to avoid the mutual interference of the power supply box 430 and the pulsed light sterilization component 420 during installation, so that both the power supply box 430 and the pulsed light sterilization component 420 can be arranged on the evaporator bracket 150, and the installation difficulty of the power supply box 430 and the pulsed light sterilization component 420 can be reduced.

[0102] In some embodiments, one of the evaporator bracket 150 and the power supply box 430 is provided with a first connection hole and the other is provided with a first mating hole. The power supply box 430 is fixed to the evaporator bracket 150 through a first fastener, and the first fastener passes through the first connection hole and the first mating hole. Here, it means that when the evaporator bracket 150 is provided with a first connection hole, the power supply box 430 is provided with a first mating hole; when the power supply box 430 is provided with a first connection hole, the evaporator bracket 150 is provided with a first mating hole. In this way, when the first fastener passes through the first connection hole and the first mating hole, the power supply box 430 can be fixed to the evaporator bracket 150 through the first fastener, so as to realize the fixed connection between the power supply box 430 and the evaporator bracket 150, thereby facilitating the support of the power supply box 430 by the evaporator bracket 150, improving the position stability of the power supply box 430, and at the same time reducing the connection difficulty between the power supply box 430 and the evaporator bracket 150.

[0103] Optionally, the first fastener is a fastening bolt or a fastening screw, etc., so as to facilitate the fixed connection between the power supply box 430 and the evaporator bracket 150 through the first fastener.

[0104] It should also be noted that using the first fastener to achieve the fixed connection between the power supply box 430 and the evaporator bracket 150 can also make the power supply box 430 and the evaporator bracket 150 form a detachable connection, so as to reduce the installation and disassembly difficulty of the power supply box 430, and thus reduce the maintenance difficulty of the power supply box 430.

[0105] In some embodiments, as shown in Figure 2 , Figure 7 and Figure 8 , one end of the pulsed light sterilization component 420 is connected to the evaporator bracket 150 and the other end is suspended in the air duct 130. In this way, while realizing the installation of the pulsed light sterilization component 420 on the evaporator bracket 150, the pulsed light sterilization component 420 can be arranged directly opposite to the evaporator 200, so as to facilitate the use of the pulsed light sterilization component 420 to sterilize the evaporator 200, avoid the residue of bacteria on the evaporator 200, and ensure the cleanliness of the air flowing through the evaporator 200.

[0106] At the same time, through the above setting, the other end of the pulsed light sterilization component 420 can be formed as a free end, and there is no obstruction at the other end of the pulsed light sterilization component 420, so that the other end of the pulsed light sterilization component 420 can emit light to the air duct 130, thereby increasing the irradiation range and improving the sterilization effect.

[0107] In some embodiments, one end of the pulsed light sterilization component 420 is connected to the evaporator bracket 150 through a second fastener; and / or, a clamping member is provided at one end of the pulsed light sterilization component 420 for clamping connection with the evaporator bracket 150. Here, it means that one end of the pulsed light sterilization component 420 connected to the evaporator bracket 150 is connected to the evaporator bracket 150 through a second fastener; or, a clamping member is provided at one end of the pulsed light sterilization component 420 connected to the evaporator bracket 150 for clamping connection with the evaporator bracket 150; or, one end of the pulsed light sterilization component 420 connected to the evaporator bracket 150 is connected to the evaporator bracket 150 through a second fastener and a clamping member is provided at one end of the pulsed light sterilization component 420 connected to the evaporator bracket 150 for clamping connection with the evaporator bracket 150, so as to realize the fixed connection between one end of the pulsed light sterilization component 420 and the evaporator bracket 150, facilitate the use of the evaporator bracket 150 to support the pulsed light sterilization component 420, improve the position stability of the pulsed light sterilization component 420, and reduce the connection difficulty between the pulsed light sterilization component 420 and the evaporator bracket 150.

[0108] Among them, when one end of the pulsed light sterilization component 420 connected to the evaporator bracket 150 is connected to the evaporator bracket 150 through a second fastener and a clamping member is provided at the end of the pulsed light sterilization component 420 connected to the evaporator bracket 150 for clamping connection with the evaporator bracket 150, while realizing the fixed connection between the pulsed light sterilization component 420 and the evaporator bracket 150, the connection strength between the pulsed light sterilization component 420 and the evaporator bracket 150 can be increased, and the connection difficulty between the pulsed light sterilization component 420 and the evaporator bracket 150 can be reduced.

[0109] In a specific example, when one end of the pulsed light sterilization component 420 connected to the evaporator bracket 150 is connected to the evaporator bracket 150 through a second fastener and a clamping member is provided at the end of the pulsed light sterilization component 420 connected to the evaporator bracket 150 for clamping connection with the evaporator bracket 150, the clamping cooperation between one end of the pulsed light sterilization component 420 and the evaporator bracket 150 can be first realized by using the clamping member, and then the fixed connection between the pulsed light sterilization component 420 and the evaporator bracket 150 can be realized by using the second fastener, so as to reduce the connection difficulty between the pulsed light sterilization component 420 and the evaporator bracket 150.

[0110] At the same time, the above setting can also make the pulsed light sterilization component 420 and the evaporator bracket 150 form a detachable connection, so as to reduce the installation and disassembly difficulty of the pulsed light sterilization component 420, and thus reduce the maintenance difficulty of the pulsed light sterilization component 420.

[0111] Optionally, the second fastener is a fastening bolt or a fastening screw, etc., so as to facilitate the use of the second fastener to realize the fixed connection between the pulsed light sterilization component 420 and the evaporator bracket 150.

[0112] In some embodiments, a second connection hole is provided in one of the evaporator bracket 150 and one end of the pulsed light sterilization component 420, and a second mating hole is provided in the other, and the second fastener passes through the second connection hole and the second mating hole, so that one end of the pulsed light sterilization component 420 is fixed to the evaporator bracket 150 through the second fastener, thereby realizing the fixed connection between the evaporator bracket 150 and the pulsed light sterilization component 420.

[0113] Optionally, the clamping member is a first buckle, the first buckle is provided at one end of the pulsed light sterilization component 420, and a first clamping hole matched with the first buckle is provided on the evaporator bracket 150, and the first buckle is clamped in the first clamping hole to realize the clamping connection between the pulsed light sterilization component 420 and the evaporator bracket 150, so as to realize the installation of the pulsed light sterilization component 420 on the evaporator bracket 150.

[0114] In some embodiments, there are multiple first buckles, which are spaced apart and arranged at one end of the pulsed light sterilization component 420. The evaporator bracket 150 is provided with multiple first holes that cooperate with the first buckles. In this way, while realizing the fixed connection between the pulsed light sterilization component 420 and the evaporator bracket 150, the connection strength of the pulsed light sterilization component 420 disposed on the evaporator bracket 150 can be improved to ensure the position stability of the pulsed light sterilization component 420.

[0115] In the description of the present invention, unless otherwise specified, the meaning of "multiple" is two or more.

[0116] Of course, in some other embodiments, first buckles can also be provided on the evaporator bracket 150, and first holes that cooperate with the first buckles can be provided at one end of the pulsed light sterilization component 420. In this way, the snap connection between the pulsed light sterilization component 420 and the evaporator bracket 150 can also be realized, and the present application does not make specific limitations.

[0117] In some embodiments, the evaporator bracket 150 is provided with reinforcing ribs for improving the structural strength of the evaporator bracket 150. In this way, when the power supply box 430 and the pulsed light sterilization component 420 are disposed on the evaporator bracket 150, the evaporator bracket 150 can stably support the power supply box 430 and the pulsed light sterilization component 420, so as to improve the position stability of the power supply box 430 and the pulsed light sterilization component 420, thereby ensuring the working performance of the power supply box 430 and the pulsed light sterilization component 420.

[0118] In some embodiments, as Figure 13 shown, the pulsed light sterilization component 420 includes a lamp housing 421 and a pulsed lamp body 422. An accommodation cavity 4211 is defined inside the lamp housing 421. The lamp housing 421 has multiple light-transmitting holes 4212, and the multiple light-transmitting holes 4212 communicate with the accommodation cavity 4211. The pulsed lamp body 422 is disposed inside the accommodation cavity 4211. Among them, by disposing the pulsed lamp body 422 inside the accommodation cavity 4211, the pulsed lamp body 422 is disposed inside the lamp housing 421, that is, the lamp housing 421 provides an installation space for the pulsed lamp body 422, which is convenient for using the lamp housing 421 to support and ensure the pulsed lamp body 422. In this way, while ensuring the position stability of the pulsed lamp body 422, the service life of the pulsed lamp body 422 can be extended. The pulsed lamp body 422 is mainly used to emit strong light, which can be used to sterilize and disinfect the interior of the air conditioner indoor unit 1000, improve the cleanliness of the interior of the air conditioner indoor unit 1000, and further improve the cleanliness of the air blown by the air conditioner indoor unit 1000, thereby improving the user experience.

[0119] Meanwhile, by providing a plurality of light-transmitting holes 4212 on the lamp housing 421 that communicate with the accommodation cavity 4211, the accommodation cavity 4211 can be communicated with the external space through the light-transmitting holes 4212, so as to ensure that the strong light emitted by the pulsed lamp body 422 can penetrate through the plurality of light-transmitting holes 4212 and irradiate into the air conditioner indoor unit 1000, realizing the sterilization effect of the pulsed light sterilization component 420, thereby completing the sterilization treatment of the air conditioner indoor unit 1000.

[0120] In addition, by providing a plurality of light-transmitting holes 4212, the cooperation of the plurality of light-transmitting holes 4212 can increase the illumination range of the pulsed lamp body 422, and further increase the treatment area of the pulsed light sterilization component 420 for sterilization and disinfection. In this way, the colony count of the air conditioner indoor unit 1000 can be effectively reduced, the cleanliness of the air supplied by the air conditioner indoor unit 1000 can be improved, and the user experience can be enhanced.

[0121] It should be noted that the above-mentioned "a plurality of" means two or more.

[0122] In some embodiments, the number of the light-transmitting holes 4212 is two, three or more. Among them, through simulation experiments, it is obtained that by adopting the above-mentioned pulsed light sterilization component 420, the illumination treatment range of the air conditioner indoor unit 1000 is increased by at least 20%, thereby increasing the cleanliness of the air conditioner indoor unit 1000 and enhancing the user experience.

[0123] In some embodiments, the plurality of light-transmitting holes 4212 are disposed opposite to the pulsed lamp body 422 to ensure that the strong light emitted by the pulsed lamp body 422 can effectively irradiate into the air conditioner indoor unit 1000 through the plurality of light-transmitting holes 4212, and improve the sterilization effect of the pulsed light sterilization component 420.

[0124] It should be noted that the strong light emitted by the above-mentioned pulsed lamp body 422 can be ultraviolet light, infrared light, etc., to ensure that the strong light emitted by the pulsed lamp body 422 can effectively remove bacteria, viruses, etc. in the air conditioner indoor unit 1000, thereby ensuring the sterilization effect of the pulsed light sterilization component 420.

[0125] Among them, when the strong light emitted by the pulsed lamp body 422 is ultraviolet light, by irradiating bacteria, viruses and other microorganisms with ultraviolet light, the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of the microorganism body is damaged, causing DNA strand breakage, cross-linking rupture of nucleic acid and protein, resulting in growth cell death and reproductive cell death, achieving the effect of sterilization and disinfection, thereby realizing the removal of harmful substances such as bacteria and viruses in the air conditioner indoor unit 1000 by using the pulsed lamp body 422.

[0126] In some embodiments, the pulsed lamp body 422 is a xenon lamp, so that the pulsed lamp body 422 can generate ultraviolet light, thereby achieving the purpose of sterilizing with the pulsed light sterilization component 420, reducing the colony count in the air conditioner indoor unit 1000, improving the cleanliness of the air supplied by the air conditioner indoor unit 1000, and enhancing the user experience.

[0127] In some embodiments, the pulsed lamp body 422 further includes an electrical connection wire, which is connected to one end of the pulsed lamp body 422 and is used for electrically connecting to the power supply box 430, so as to facilitate power supply to the pulsed light sterilization component 420 by the power supply box 430, enabling the pulsed lamp body 422 to work normally and emit strong light.

[0128] In some embodiments, in combination Figure 2 、 Figure 10 and Figure 13 As shown in, the lamp housing 421 includes: a lamp base 4213 and a lamp cover 4214. The lamp base 4213 is disposed opposite to the evaporator 200 and the length direction of the lamp base 4213 extends along the length direction of the evaporator 200. The lamp cover 4214 covers the side of the lamp base 4213 facing away from the evaporator 200 and cooperates with the lamp base 4213 to define a receiving cavity 4211. At least one of the lamp base 4213 and the lamp cover 4214 is provided with a light-transmitting hole 4212. Among them, by setting the lamp housing 421 to include the lamp base 4213 and the lamp cover 4214, and covering the lamp cover 4214 on the side of the lamp base 4213 facing away from the evaporator 200 and cooperating with the lamp base 4213 to define the receiving cavity 4211, the molding difficulty of the lamp housing 421 and the receiving cavity 4211 can be reduced, thereby facilitating the placement of the pulsed lamp body 422 in the receiving cavity 4211; by setting the lamp base 4213 opposite to the evaporator 200 and setting the length direction of the lamp base 4213 to extend along the length direction of the evaporator 200, while ensuring that the pulsed light sterilization component 420 can be disposed directly opposite to the evaporator 200, the area of the pulsed light sterilization component 420 facing the evaporator 200 can also be increased, thereby enhancing the sterilization effect of the pulsed light sterilization component 420.

[0129] At the same time, by providing the light-transmitting hole 4212 in at least one of the lamp base 4213 and the lamp cover 4214, the light-transmitting hole 4212 can be provided on the lamp housing 421, ensuring that the strong light emitted by the pulsed lamp body 422 can irradiate into the air conditioner indoor unit 1000 and realizing the sterilization function of the pulsed light sterilization component 420.

[0130] In some embodiments, the pulsed lamp body 422 extends along the length direction of the lamp base 4213 and is disposed in the receiving cavity 4211. By setting the length direction of the lamp base 4213 to extend along the length direction of the evaporator 200, the installation adaptability between the lamp base 4213 and the pulsed lamp body 422 can also be increased to ensure that the pulsed lamp body 422 can be effectively disposed in the lamp housing 421.

[0131] In some embodiments, the lamp cover 4214 is detachably connected to the lamp base 4213, facilitating the installation of the pulsed lamp body 422. At the same time, it can also reduce the difficulty of assembling and disassembling the pulsed light sterilization component 420 and improve the convenience of maintaining the pulsed light sterilization component 420.

[0132] Optionally, the lamp cover 4214 and the lamp base 4213 are snap-connected, thereby realizing the detachable connection between the lamp cover 4214 and the lamp base 4213 and reducing the difficulty of assembling and disassembling the pulsed light sterilization component 420.

[0133] In some embodiments, as Figure 14 shown, the lamp base 4213 is provided with a plurality of second card holes 4218, and the lamp cover 4214 is provided with a plurality of second buckles that cooperate with the second card holes 4218. The second buckles are snap-fitted into the second card holes 4218 to realize the snap connection between the lamp cover 4214 and the lamp base 4213, that is, to realize the detachable connection between the lamp cover 4214 and the lamp base 4213 and reduce the difficulty of assembling and disassembling the pulsed light sterilization component 420.

[0134] Of course, in some other embodiments, the lamp cover 4214 is provided with a plurality of second card holes 4218, and the lamp base 4213 is provided with second buckles that cooperate with the second card holes 4218. In this way, the snap connection between the lamp cover 4214 and the lamp base 4213 can also be realized, and the present application does not make specific limitations.

[0147] In the description of the present invention, the features defined as "first", "second", and "third" may explicitly or implicitly include one or more of such features, which are used to distinguish and describe features, without order or importance.

[0148] In some embodiments, such as Figure 17As shown, the negative ion sterilization component 410 has a plurality of negative ion release parts 411, and the plurality of negative ion release parts 411 are arranged at intervals. Among them, the negative ion release part 411 mainly releases a large number of free electrons after the negative ion sterilization component 410 is powered on. These free electrons are captured by oxygen molecules in the air, thereby generating negative oxygen ions in the air, that is, negative ions. After the generated negative ions come into contact with bacteria, viruses, etc., they can destroy the molecular protein structures of bacteria, viruses, etc., causing their structures to change, the protein bipolarity to reverse or energy transfer, so that bacteria, viruses, etc. die, achieving the purpose of sterilization using the negative ion sterilization component 410.

[0149] At the same time, by setting the negative ion release parts 411 into a plurality, the cooperation of the plurality of negative ion release parts 411 can improve the efficiency of the negative ion sterilization component 410 in generating negative ions, thereby enhancing the sterilization ability of the negative ion sterilization component 410.

[0150] In some embodiments, the negative ion release part 411 is made of materials such as carbon fiber and tungsten wire. To ensure that the negative ion release part 411 can release a large number of free electrons after the negative ion sterilization component 410 is powered on, thus ensuring the working performance of the negative ion sterilization component 410.

[0151] In some embodiments, as Figure 17 shown, the number of the negative ion release parts 411 is greater than or equal to 3. To further ensure the efficiency of the negative ion sterilization component 410 in generating negative ions, thereby enhancing the sterilization ability of the negative ion sterilization component 410.

[0152] Optionally, as Figure 17 shown, the number of the negative ion release parts 411 is equal to 3, and the three negative ion release parts 411 are arranged at intervals. The cooperation of the three negative ion release parts 411 can, while increasing the number of negative ions generated by the negative ion sterilization component 410 and improving the efficiency of the negative ion sterilization component 410 in generating negative ions, also reduce the manufacturing cost of the negative ion sterilization component 410 and simplify the structure of the negative ion sterilization component 410.

[0153] Optionally, as Figure 17 shown, the three negative ion release parts 411 enclose a triangular structure. Through experiments and theoretical simulation and emulation, it is obtained that by setting three negative ion release parts 411 and enclosing the three negative ion release parts 411 into a triangular structure, the sterilization effect is the best, and the sterilization ability of the negative ion sterilization component 410 can reach more than 99.5%.

[0154] In some embodiments, in combination with Figure 2 and Figure 3As shown, the housing assembly 100 further includes: a volute tongue 160 and an air outlet frame 170. An air outlet passage 180 is defined between the air outlet frame 170 and the volute tongue 160. The air outlet passage 180 communicates with the air outlet 120 and the air duct 130. The negative ion sterilization component 410 is disposed on the air outlet frame 170. In this way, while realizing the support of the negative ion sterilization component 410 by the air outlet frame 170, the negative ion sterilization component 410 can be disposed close to the air outlet 120, so as to facilitate the use of the negative ion sterilization component 410 to sterilize the air flowing through it, and enable the negative ions generated by the negative ion sterilization component 410 to flow through the room through the air outlet 120, so as to facilitate the use of the negative ion sterilization component 410 to sterilize the indoor air.

[0155] It should be noted that realizing the support of the negative ion sterilization component 410 by the air outlet frame 170 can reduce the fixing difficulty of the negative ion sterilization component 410, thereby improving the position stability of the negative ion sterilization component 410 to ensure the working performance of the negative ion sterilization component 410.

[0156] In some embodiments, in combination with Figure 3 , Figure 17 and Figure 18 As shown, the air outlet frame 170 defines an installation cavity 171 opening towards the air outlet passage 180. The negative ion sterilization component 410 is disposed in the installation cavity 171 and a plurality of negative ion release parts 411 are exposed from the opening. To realize the arrangement of a plurality of negative ion release parts 411 in the air outlet passage 180, so as to facilitate the use of the negative ion sterilization component 410 to sterilize the air flowing through the air outlet passage 180, and enable the negative ions to flow through the room following the air, so as to facilitate the use of the negative ion sterilization component 410 to sterilize the indoor air.

[0157] At the same time, by disposing the negative ion sterilization component 410 in the installation cavity 171, on the one hand, the air outlet frame 170 can be used to protect the negative ion sterilization component 410 to extend the service life of the negative ion sterilization component 410; on the other hand, the air outlet frame 170 can also be used to block the negative ion sterilization component 410 to prevent the user from directly observing the negative ion sterilization component 410, so as to improve the aesthetic appearance of the air conditioner indoor unit 1000.

[0158] In some embodiments, in combination with Figure 3 , Figure 17 and Figure 18 As shown, the air outlet frame 170 is disposed on the chassis 140 of the housing assembly 100. The air outlet frame 170 and the chassis 140 cooperate to form the installation cavity 171. The negative ion sterilization component 410 is connected to the chassis 140 and is located in the installation cavity 171. To facilitate the use of the chassis 140 to support the negative ion sterilization component 410 and improve the position stability of the negative ion sterilization component 410.

[0159] In some embodiments, the negative ion sterilization component 410 can be pre-installed on the chassis 140 in advance and can be made into inserts during mold opening, which is convenient for subsequent selection at any time.

[0160] Optionally, the negative ion sterilization component 410 is inserted and cooperated with the chassis 140 to reduce the connection difficulty between the negative ion sterilization component 410 and the chassis 140, thereby reducing the assembly difficulty of the negative ion sterilization component 410 and improving the assembly efficiency.

[0161] In some embodiments, as shown in Figure 17 、 Figure 19 and Figure 20 the negative ion sterilization component 410 includes a mounting base 412 and a mounting cover 413. The mounting cover 413 is disposed on the mounting base 412 and defines a fitting cavity with the mounting base 412. A through hole penetrating in the thickness direction is formed on the mounting cover 413, and the through hole communicates with the fitting cavity. A plurality of negative ion release parts 411 are disposed in the fitting cavity, and one end of the negative ion release part 411 extends out of the fitting cavity through the through hole to ensure the working performance of the negative ion release part 411.

[0162] At the same time, by setting the negative ion sterilization component 410 to include the mounting base 412 and the mounting cover 413, the molding difficulty of the negative ion sterilization component 410 can also be reduced, and it is convenient to use the cooperation of the mounting base 412 and the mounting cover 413 to limit the position of the negative ion release part 411, thereby improving the position stability of the negative ion release part 411.

[0163] In some embodiments, as shown in Figure 20 the negative ion sterilization component 410 includes a conductive part 414. The conductive part 414 is formed with a plurality of extended legs, and each negative ion release part 411 is correspondingly disposed on an extended leg. This is convenient for supplying power to the negative ion release part 411, so that the negative ion sterilization component 410 can generate negative ions when powered on, thereby ensuring the working performance of the negative ion sterilization component 410.

[0164] At the same time, by providing a plurality of extended legs, a plurality of negative ion release parts 411 can also be powered by one conductive part 414, which is convenient for controlling the operation and stop of the negative ion release parts 411, and makes the plurality of negative ion release parts 411 connected in parallel with each other. The plurality of negative ion release parts 411 work independently and do not affect each other.

[0165] In some embodiments, there are a plurality of negative ion sterilization components 410, and the plurality of negative ion sterilization components 410 are spaced apart on the chassis 140. The cooperation of the plurality of negative ion sterilization components 410 can enhance the sterilization ability of the air conditioner indoor unit 1000, and can also make the negative ions generated by the air conditioner indoor unit 1000 more evenly distributed, thereby improving the purification ability of the air conditioner indoor unit 1000.

The plurality of wind guiding vanes 192 are arranged at intervals in the length direction of the connecting rod 191. The negative ion sterilization assembly 410 is opposite to the space between two adjacent wind guiding vanes 192. Among them, by providing the wind guiding assembly 190, it is convenient to use the wind guiding assembly 190 to guide the flow direction of the air in the air outlet passage 180, so as to achieve large-range air outlet of the air conditioner indoor unit 1000 and ensure the working performance of the air conditioner indoor unit 1000.

[0167] At the same time, by arranging the negative ion sterilization assembly 410 opposite to the space between two adjacent wind guiding vanes 192, the negative ion sterilization assembly 410 can be located between two adjacent wind guiding vanes 192, avoiding the negative ion sterilization assembly 410 being arranged close to the wind guiding vane 192, thereby avoiding the negative ion sterilization assembly 410 interfering with the rotation of the wind guiding vane 192 and ensuring the working performance of the wind guiding vane 192. And since the wind guiding vane 192 is generally made of plastic material, through the above arrangement, it can also be avoided that the negative ions generated by the negative ion sterilization assembly 410 are absorbed by the wind guiding vane 192, so as to ensure the sterilization ability of the negative ion sterilization assembly 410.

[0168] In some embodiments, the negative ion sterilization assembly 410 is directly opposite to the middle of the space between two adjacent wind guiding vanes 192, so that the distance between the negative ion sterilization assembly 410 and two adjacent wind guiding vanes 192 can be made consistent, further avoiding the negative ion sterilization assembly 410 being arranged close to the wind guiding vane 192, thereby avoiding the negative ions generated by the negative ion sterilization assembly 410 being absorbed by the wind guiding vane 192 and improving the sterilization ability of the negative ion sterilization assembly 410.
