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

[0060] Combination Figure 1 , Figure 2 and Figure 3 As shown, an air-conditioning indoor unit 1000 according to an embodiment of the utility model includes: a casing assembly 100, an evaporator 200, a fan 300 and a sterilization device 400.

[0061] Among them, combined Figure 1 and Figure 3 As shown, the housing assembly 100 has an air inlet 110, an air outlet 120 and an air duct 130, and the air duct 130 connects 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 that the air is transported to the room through the air outlet 120, so as to achieve the purpose of adjusting the indoor air temperature, thereby improving the indoor comfort and ensuring the working performance of the air conditioner indoor unit 1000.

[0062] like Figure 3 As shown, the evaporator 200 and the fan 300 are both disposed 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, the evaporator 200 and the fan 300 are both disposed in the air duct 130, and when the 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 facilitate the delivery of air to the room through the air outlet 120, and 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 temperature of the air, so that the air delivered to the room through the air outlet 120 can effectively adjust the indoor temperature to ensure the working performance of the air-conditioning indoor unit 1000.

[0064] It should be noted that the evaporator 200 and the fan 300 of the present application are both existing technologies well known to those skilled in the art and will not be described in detail here.

[0065] Combination Figure 1 , Figure 2 and Figure 3 As shown, the sterilization device 400 includes a negative ion sterilization component 410, a pulse 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 pulse light sterilization component 420 respectively. The negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430 are independently arranged in the housing component 100.

[0066] Among them, by setting up a negative ion sterilization component 410, a pulse light sterilization component 420 and a power supply box 430, and configuring the power supply box 430 to supply power to the negative ion sterilization component 410 and the pulse light sterilization component 420, the negative ion sterilization component 410 and the pulse light sterilization component 420 can effectively perform 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, and the negative ions can combine with dust, bacteria, viruses and other microorganisms in the air to change their structure, thereby achieving the purpose of sterilization and realizing air purification; when the power supply box 430 is used to supply power to the pulse light sterilization component 420, the pulse light sterilization component 420 can emit sterilization light, such as ultraviolet light, infrared light, etc., so as to remove bacteria, viruses, etc. in the air, thereby removing bacteria, viruses, etc. in the air-conditioning indoor unit 1000 and ensuring the cleanliness of the air discharged from the air-conditioning indoor unit 1000.

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

[0069] At the same time, by independently arranging the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430 on the housing component 100, the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430 can be formed into three separate parts. In this way, when processing the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430, the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430 can be processed separately to reduce the processing of the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430. The difficulty of assembly is reduced, and during assembly, the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430 can be assembled separately, thereby reducing the difficulty of assembling the negative ion sterilization component 410, the pulse 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 maintenance can also be disassembled separately, without the need to dismantle the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430 as a whole, thereby reducing the difficulty of maintenance of the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430.

[0070] That is to say, the present application independently arranges the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430 in the casing component 100. On the first hand, it can reduce the manufacturing difficulty of the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430; on the second hand, it can improve the assembly efficiency of the negative ion sterilization component 410, the pulse 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 pulse light sterilization component 420 and the power supply box 430.

[0071] It is also worth noting that the present application utilizes a power supply box 430 to supply power to the negative ion sterilization component 410 and the pulse light sterilization component 420 respectively, so that the negative ion sterilization component 410 and the pulse light sterilization component 420 can share one power supply box 430. This can reduce the number of power supply boxes 430 used, thereby simplifying the structure of the air-conditioning indoor unit 1000, reducing the difficulty of assembling the air-conditioning indoor unit 1000, and reducing the manufacturing cost of the air-conditioning indoor unit 1000. It can also save the space occupied by the power supply box 430, which is conducive to the compact setting of the air-conditioning indoor unit 1000.

[0072] It can be seen from the above structure that the air-conditioning indoor unit 1000 of the embodiment of the utility model, by setting a negative ion sterilization component 410, a pulse light sterilization component 420 and a power supply box 430, enables the air-conditioning indoor unit 1000 to emit sterilization light and release ions that can kill bacteria, thereby achieving the purpose of double-stage purification and sterilization, improving the sterilization and purification efficiency of the air-conditioning indoor unit 1000, and thus improving the cleanliness of the air discharged from the air-conditioning indoor unit 1000.

[0073] At the same time, the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430 are independently arranged in the casing component 100, so that the negative ion sterilization component 410, the pulse 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 pulse light sterilization component 420 and the power supply box 430, improving the assembly efficiency of the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430, and reducing the maintenance difficulty of the negative ion sterilization component 410, the pulse 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 pulse light sterilization component 420 and a power supply box 430, and the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430 are independently arranged in the casing component 100, so that the air-conditioning indoor unit 1000 can achieve two-stage purification and sterilization, and the maintenance difficulty of the air-conditioning indoor unit 1000 can also be reduced, and it is beneficial to improve the maintenance efficiency of the air-conditioning indoor unit 1000.

[0075] In some embodiments, in combination 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 pulse light sterilization component 420 through a second wire. Thereby, the power supply box 430 can be connected to the negative ion sterilization component 410 and the pulse light sterilization component 420 at the same time, so as to achieve the purpose of using the power supply box 430 to supply power to the negative ion sterilization component 410 and the pulse light sterilization component 420 respectively, so as to ensure the working performance of the negative ion sterilization component 410 and the pulse light sterilization component 420. In addition, through the above-mentioned arrangement, the negative ion sterilization component 410 and the pulse light sterilization component 420 can be controlled by separate circuit boards respectively, so as to reduce the control difficulty of the negative ion sterilization component 410 and the pulse light sterilization component 420. In this way, when it is impossible to supply power to the negative ion sterilization component 410 or the pulse light sterilization component 420 in the future, only one of the circuit boards needs to be checked, so as to reduce the maintenance difficulty.

[0076] At the same time, through the above-mentioned setting, it is also possible to achieve the purpose of using one power supply box 430 to simultaneously control the negative ion sterilization component 410 and the pulse light sterilization component 420, so as to reduce the number of power supply boxes 430 used, thereby simplifying the structure of the air-conditioning indoor unit 1000, reducing the difficulty of assembling the air-conditioning indoor unit 1000, and reducing the manufacturing cost of the air-conditioning 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 safety of use 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 positional 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 Figure 5 and Figure 6As shown, a separation rib 4311 is provided in the box body 431, and the separation rib 4311 separates the inner cavity of the box body 431 into a first cavity 4312 and a second cavity 4313. The first circuit board 432 is provided in the first cavity 4312, and the second circuit board 433 is provided in the second cavity 4313. In this way, while the first circuit board 432 and the second circuit board 433 are both provided in the box body 431, the first circuit board 432 and the second circuit board 433 can also be separated from each other, avoiding mutual interference between the first circuit board 432 and the second circuit board 433, thereby reducing the difficulty of installing the first circuit board 432 and the second circuit board 433, and ensuring the working performance of the first circuit board 432 and the second circuit board 433.

[0079] In some embodiments, in combination 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. This ensures that the first circuit board 432 can be arranged in the first chamber 4312 and the second circuit board 433 can be arranged in the second chamber 4313, while further reducing the difficulty of installing the first circuit board 432 and the second circuit board 433. The first chamber 4312 can be used 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 positional 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, the first chamber 4312 and the second chamber 4313 are respectively filled with sealing glue to seal the first circuit board 432 and the second circuit board 433, and the height of the sealing glue in the first chamber 4312 is not equal to the height of the sealing glue in the second chamber 4313. In particular, by sealing the first circuit board 432 and the second circuit board 433 with the sealing glue, the first circuit board 432 and the second circuit board 433 are protected and fixed at the same time, 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 in the box body 431.

[0081] In addition, by setting the height of the sealing glue in the first chamber 4312 to be unequal to the height of the sealing glue in the second chamber 4313, it is also convenient for users to distinguish between the first chamber 4312 and the second chamber 4313, thereby reducing the difficulty of subsequent maintenance of the first circuit board 432 and the second circuit board 433.

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

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

[0084] It should be noted that since the chamber size of the first chamber 4312 is larger than the chamber size of the second chamber 4313, by setting the height of the sealant in the first chamber 4312 to be smaller than the height of the sealant in the second chamber 4313, the amount of sealant in the first chamber 4312 can be reduced, thereby reducing the sealing cost of the first chamber 4312, and helping to reduce the weight of the power supply box 430 and reduce the difficulty of installing the power supply box 430.

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

[0086] In some embodiments, in combination Figure 5 and Figure 6 As shown, the box body 431 has a first outlet 4314 and a second outlet 4315, and the power supply box 430 also 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 is passed through the first 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 is passed through the second outlet 4315 to be connected to the second wire. In this way, the electrical connection between the first circuit board 432 and the negative ion sterilization component 410 and the electrical connection between the second circuit board 433 and the pulse light sterilization component 420 are realized, so that the power supply box 430 is used to supply power to the negative ion sterilization component 410 and the pulse light sterilization component 420 respectively, so as to ensure the working performance of the negative ion sterilization component 410 and the pulse light sterilization component 420, and reduce the difficulty of connecting the power supply box 430 with the negative ion sterilization component 410 and the pulse light sterilization component 420 respectively.

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

[0088] In some embodiments, the protective shell 434 is a metal shell. On the one hand, the metal shell can make the protective shell 434 have a certain structural strength, so that it is convenient to use the protective shell 434 to protect the box body 431, and improve the protection performance of the protective shell 434; on the other hand, it can also prevent the first circuit board 432 and the second circuit board 433 from breaking through the potting glue and splashing other components after the explosion, thereby avoiding large-scale fire and safety hazards, so as to improve the performance of the power supply box 430.

[0089] In some embodiments, the protective shell 434 is composed of two relative parts, and the power supply box 430 is arranged between the two relative parts of the protective shell 434 to reduce the difficulty of assembling the power supply box 430 and the protective shell 434, thereby facilitating the use of the protective shell 434 to protect the box body 431.

[0090] In some embodiments, in combination Figure 5 and Figure 6 As shown, the two relative parts of the protective shell 434 are both provided with a connecting ear 4342, and the two relative parts of the protective shell 434 are fixedly connected by a fastening connector passing through the connecting ear 4342; and / or, one of the protective shells 434 is provided with a connecting protrusion 4341, and the other protective shell 434 is provided with a limiting hole matched with the connecting protrusion 4341. Here, it means that the two relative parts of the protective shell 434 are both provided with a connecting ear 4342, and the two relative parts of the protective shell 434 are fixedly connected by a fastening connector passing through the connecting ear 4342; or, in the two relative parts of the protective shell 434, one of the protective shells 434 is provided with a connecting protrusion 4341, and the other protective shell 434 is provided with a limiting hole matched with the connecting protrusion 4341, and the connecting protrusion 4341 is limitedly matched in the limiting hole to achieve the fixed connection of the two relative parts of the protective shell 434; Alternatively, connecting ears 4342 are provided on the two relative parts of the protective shell 434, and the two relative parts of the protective shell 434 are fixedly connected by a fastening connector passing through the connecting ears 4342, and one of the protective shells 434 is provided with a connecting protrusion 4341, and the other protective shell 434 is provided with a limiting hole matching the connecting protrusion 4341. In this way, while achieving fixed connection between the two relative parts of the protective shell 434, the structural strength of the protective shell 434 can be improved and the molding difficulty of the protective shell 434 can be reduced.

[0091] The fastening connector mentioned here may be a fastening bolt or a fastening screw, etc., so as to realize the assembly connection of the protective shell 434 by using the fastening connector.

[0092] In some embodiments, Figure 3 As shown, the negative ion sterilization component 410 is located downstream of the fan 300 in the airflow direction, and the pulse light sterilization component 420 is located between the evaporator 200 and the fan 300 in the airflow direction. Among them, by arranging the negative ion sterilization component 410 downstream of the fan 300, the negative ion sterilization component 410 can be arranged close to the air outlet 120, so that while the negative ion sterilization component 410 is used to sterilize the air flowing through it, the negative ions can also follow the air flowing through the room, so that the negative ion sterilization component 410 can be used to settle PM2.5 and other particulate matter in the room, play a dust removal role, thereby improving the indoor air quality to ensure the user experience.

[0093] At the same time, in the direction of air flow, by setting the pulse light sterilization component 420 to be located between the evaporator 200 and the fan 300, the pulse light sterilization component 420 can be set close to the evaporator 200. In this way, while the pulse light sterilization component 420 is used to sterilize the air flowing through it, the pulse light sterilization component 420 can also sterilize the evaporator 200, thereby ensuring the cleanliness of the airflow after passing through the evaporator 200 and achieving 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 easily bred on the surface of the evaporator 200. When the air flows through the evaporator 200, bacteria, viruses, etc. will be carried into the indoor space, thereby causing the air quality in the indoor space to deteriorate. Therefore, the present application arranges the pulse light sterilization component 420 to be located between the evaporator 200 and the fan 300 to effectively solve the above problem and improve the working performance of the air-conditioning indoor unit 1000.

[0095] It is also worth noting that by arranging the negative ion sterilization component 410 to be located downstream of the fan 300 in the direction of the air flow and arranging the pulse light sterilization component 420 to be located between the evaporator 200 and the fan 300 in the direction of the air flow, the negative ion sterilization component 410 and the pulse light sterilization component 420 can be arranged in sequence in the direction of the air flow, thereby facilitating the use of the negative ion sterilization component 410 and the pulse light sterilization component 420 to cooperate in performing multiple sterilization treatments on the air entering the air-conditioning indoor unit 1000 to improve the cleanliness of the air.

[0096] In some embodiments, in combination Figure 2 , Figure 3 and Figure 4As shown, the housing 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, the evaporator bracket 150 can be supported by the chassis 140 to improve the position stability of the evaporator bracket 150. In this way, after one end of the evaporator 200 is connected to the evaporator bracket 150, the evaporator bracket 150 can be used to support the evaporator 200 to improve the position stability of the evaporator 200, thereby ensuring the working performance of the evaporator 200, and the above arrangement can also make the overall structure of the air conditioner indoor unit 1000 stable.

[0097] Optionally, combined Figure 7 , Figure 8 and Fig.11 As shown, the power supply box 430 and the pulse light sterilization component 420 are both arranged on the evaporator bracket 150. The evaporator bracket 150 is used to support the power supply box 430 and the pulse light sterilization component 420, thereby improving the position stability of the power supply box 430 and the pulse light sterilization component 420, thereby ensuring the working performance of the power supply box 430 and the pulse light sterilization component 420.

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

[0099] In addition, the above arrangement also allows the pulse light sterilization component 420 to be arranged close to the evaporator 200, so as to facilitate the use of the pulse light sterilization component 420 to sterilize the evaporator 200, thereby ensuring the cleanliness of the airflow after passing through the evaporator 200 and achieving clean air outlet of the air conditioner indoor unit 1000.

[0100] In some embodiments, in combination Figure 2 , Fig. 9 and Fig.10As shown, the power supply box 430 is disposed on a side of the evaporator support 150 facing away from the evaporator 200 , and the pulse light sterilization component 420 is disposed on a side of the evaporator support 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 the evaporator bracket 150 is used to support the power supply box 430, the power supply box 430 can also be arranged away from the evaporator 200 to avoid the evaporator 200 interfering 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 air conditioner indoor unit 1000; by arranging the pulse light sterilization component 420 on the side of the evaporator bracket 150 facing the evaporator 200; by arranging the pulse light sterilization component 420 on the side of the evaporator bracket 150 facing the evaporator 200, the pulse light sterilization component 420 can be arranged directly opposite the evaporator 200, so that the evaporator 200 can be sterilized by the pulse light sterilization component 420, thereby ensuring the sterilization effect of the pulse light sterilization component 420.

[0101] At the same time, the above arrangement can also realize that the power supply box 430 and the pulse light sterilization component 420 are arranged on opposite sides of the evaporator bracket 150 (such as Fig.11 and Fig.12 As shown), the power supply box 430 and the pulse light sterilization component 420 are prevented from interfering with each other during installation, so that both the power supply box 430 and the pulse light sterilization component 420 can be arranged on the evaporator bracket 150, and the difficulty of installing the power supply box 430 and the pulse light sterilization component 420 is 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 matching hole, the power supply box 430 is fixed to the evaporator bracket 150 by a first fastener, and the first fastener is inserted through the first connection hole and the first matching 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 matching hole; when the power supply box 430 is provided with a first connection hole, the evaporator bracket 150 is provided with a first matching hole, so that when the first fastener is inserted through the first connection hole and the first matching hole, the power supply box 430 can be fixed to the evaporator bracket 150 by the first fastener, so as to realize the fixed connection between the power supply box 430 and the evaporator bracket 150, so as to facilitate the use of the evaporator bracket 150 to support the power supply box 430, so as to improve the position stability of the power supply box 430, and at the same time reduce the difficulty of connecting the power supply box 430 with the evaporator bracket 150.

[0103] Optionally, the first fastener is a fastening bolt or a fastening screw, etc., so that the first fastener can be used to achieve a fixed connection between the power supply box 430 and the evaporator bracket 150.

[0104] It should also be noted that the use of the first fastener to achieve a 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, thereby reducing the difficulty of assembling and disassembling the power supply box 430, thereby reducing the difficulty of repairing the power supply box 430.

[0105] In some embodiments, in combination Figure 2 , Figure 7 and Figure 8 As shown, one end of the pulse 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 the pulse light sterilization component 420 is arranged on the evaporator bracket 150, the pulse light sterilization component 420 can also be arranged directly opposite the evaporator 200, so that the pulse light sterilization component 420 is convenient for sterilizing the evaporator 200, avoiding residual bacteria in the evaporator 200, and ensuring the cleanliness of the air flowing through the evaporator 200.

[0106] At the same time, the above arrangement can also make the other end of the pulse light sterilization component 420 a free end, and make the other end of the pulse light sterilization component 420 unobstructed, so that the other end of the pulse 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 pulse light sterilization component 420 is connected to the evaporator bracket 150 via a second fastener; and / or, one end of the pulse light sterilization component 420 is provided with a snap-fit ​​component to be snap-fitted to the evaporator bracket 150 . Here, it means that one end of the pulse light sterilization component 420 connected to the evaporator bracket 150 is connected to the evaporator bracket 150 by a second fastener; or, one end of the pulse light sterilization component 420 connected to the evaporator bracket 150 is provided with a snap-in connection with the evaporator bracket 150; or, one end of the pulse light sterilization component 420 connected to the evaporator bracket 150 is connected to the evaporator bracket 150 by a second fastener and one end of the pulse light sterilization component 420 connected to the evaporator bracket 150 is provided with a snap-in connection with the evaporator bracket 150, thereby achieving a fixed connection between one end of the pulse light sterilization component 420 and the evaporator bracket 150, making it convenient to use the evaporator bracket 150 to support the pulse light sterilization component 420, so as to improve the positional stability of the pulse light sterilization component 420 and reduce the difficulty of connecting the pulse light sterilization component 420 to the evaporator bracket 150.

[0108] Among them, when one end of the pulse light sterilization component 420 connected to the evaporator bracket 150 is connected to the evaporator bracket 150 through a second fastener and one end of the pulse light sterilization component 420 connected to the evaporator bracket 150 is provided with a snap-fitting component to be snap-connected to the evaporator bracket 150, while achieving a fixed connection between the pulse light sterilization component 420 and the evaporator bracket 150, the connection strength between the pulse light sterilization component 420 and the evaporator bracket 150 can also be increased, and the difficulty of connecting the pulse light sterilization component 420 and the evaporator bracket 150 can be reduced.

[0109] In a specific example, when one end of the pulse light sterilization component 420 connected to the evaporator bracket 150 is connected to the evaporator bracket 150 through a second fastener and the end of the pulse light sterilization component 420 connected to the evaporator bracket 150 is provided with a snap-in component to snap-connect with the evaporator bracket 150, the snap-in component can be first used to achieve the snap-in fit between one end of the pulse light sterilization component 420 and the evaporator bracket 150, and then the second fastener can be used to achieve a fixed connection between the pulse light sterilization component 420 and the evaporator bracket 150, so as to reduce the difficulty of connecting the pulse light sterilization component 420 and the evaporator bracket 150.

[0110] At the same time, the above arrangement can also enable the pulse light sterilization component 420 to form a detachable connection with the evaporator bracket 150 to reduce the difficulty of assembling and disassembling the pulse light sterilization component 420 , thereby reducing the difficulty of repairing the pulse light sterilization component 420 .

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

[0112] In some embodiments, one of the ends of the evaporator bracket 150 and the pulse light sterilization component 420 is provided with a second connecting hole and the other is provided with a second matching hole, and the second fastener is passed through the second connecting hole and the second matching hole, so that one end of the pulse light sterilization component 420 is fixed to the evaporator bracket 150 through the second fastener, thereby realizing a fixed connection between the evaporator bracket 150 and the pulse light sterilization component 420.

[0113] Optionally, the snap-fit ​​component is a first snap-fit, which is disposed at one end of the pulse light sterilization component 420, and the evaporator bracket 150 is provided with a first snap-fit ​​hole that cooperates with the first snap-fit, and the first snap-fit ​​is snap-fitted into the first snap-fit ​​hole to realize the snap-fit ​​connection between the pulse light sterilization component 420 and the evaporator bracket 150, thereby realizing the pulse light sterilization component 420 being disposed on the evaporator bracket 150.

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

[0115] In the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0116] Of course, in some other embodiments, a first buckle may be provided on the evaporator bracket 150, and a first clip hole matching the first buckle may be provided on one end of the pulse light sterilization component 420, so that the pulse light sterilization component 420 and the evaporator bracket 150 can be connected by clipping, and this application does not impose any specific restrictions.

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

[0118] In some embodiments, Fig.13 As shown, the pulse light sterilization component 420 includes a lamp housing 421 and a pulse lamp body 422 . The lamp housing 421 defines a receiving cavity 4211 . The lamp housing 421 has a plurality of light-transmitting holes 4212 , and the plurality of light-transmitting holes 4212 are connected to the receiving cavity 4211 . The pulse lamp body 422 is disposed in the receiving cavity 4211 . Among them, the pulse lamp body 422 is arranged in the accommodating cavity 4211, so that the pulse lamp body 422 can be arranged in the lamp shell 421, that is, the lamp shell 421 provides an installation space for the pulse lamp body 422, so that it is convenient to use the lamp shell 421 to support and ensure the pulse lamp body 422. In this way, while ensuring the position stability of the pulse lamp body 422, the service life of the pulse lamp body 422 can also be extended. The pulse lamp body 422 is mainly used to emit strong light, which can be used to sterilize and disinfect the interior of the air-conditioning indoor unit 1000, improve the cleanliness of the interior of the air-conditioning indoor unit 1000, and then improve the cleanliness of the supply air of the air-conditioning indoor unit 1000, thereby improving the user experience.

[0119] At the same time, by arranging a plurality of light-transmitting holes 4212 connected with the accommodating cavity 4211 on the lamp housing 421, the light-transmitting holes 4212 can be used to realize the connection between the accommodating cavity 4211 and the external space, thereby ensuring that the strong light emitted by the pulse lamp body 422 can pass through the plurality of light-transmitting holes 4212 and irradiate into the air-conditioning indoor unit 1000, thereby realizing the sterilization effect of the pulse light sterilization component 420, thereby completing the sterilization treatment of the air-conditioning indoor unit 1000.

[0120] In addition, by setting up multiple light-transmitting holes 4212, the multiple light-transmitting holes 4212 can cooperate to increase the lighting range of the pulse lamp body 422, thereby increasing the treatment area of ​​the pulse light sterilization component 420 for sterilization and disinfection. This can effectively reduce the number of colonies in the air-conditioning indoor unit 1000, improve the cleanliness of the air supplied by the air-conditioning indoor unit 1000, and enhance the user experience.

[0121] It should be noted that the “plurality” mentioned above refers to two or more than two.

[0122] In some embodiments, the number of light-transmitting holes 4212 is two, three or more. Among them, through simulation experiments, it is found that by adopting the above-mentioned pulse light sterilization component 420, the light 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 improving the user experience.

[0123] In some embodiments, multiple light-transmitting holes 4212 are arranged opposite to the pulse lamp body 422 to ensure that the strong light emitted by the pulse lamp body 422 can effectively pass through the multiple light-transmitting holes 4212 to irradiate into the air-conditioning indoor unit 1000, thereby improving the sterilization effect of the pulse light sterilization component 420.

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

[0125] Among them, when the strong light emitted by the pulse lamp body 422 is ultraviolet light, the ultraviolet light irradiates bacteria, viruses and other microorganisms to destroy the molecular structure of DNA deoxyribonucleic acid or RNA ribonucleic acid in the cells of the microorganism body, causing DNA chain breakage, nucleic acid and protein cross-linking rupture, resulting in growth cell death and regenerative cell death, achieving the effect of sterilization and disinfection, thereby realizing the use of the pulse lamp body 422 to remove bacteria, viruses and other harmful substances in the air-conditioning indoor unit 1000.

[0126] In some embodiments, the pulse lamp body 422 is a xenon lamp, so that the pulse lamp body 422 can generate ultraviolet rays, thereby achieving the purpose of sterilization using the pulse light sterilization component 420, reducing the number of colonies in the air-conditioning indoor unit 1000, improving the cleanliness of the air supplied by the air-conditioning indoor unit 1000, and improving the user experience.

[0127] In some embodiments, the pulse lamp body 422 also includes an electrical connection line, which is connected to one end of the pulse lamp body 422. The electrical connection line is used to electrically connect to the power supply box 430, thereby facilitating the use of the power supply box 430 to supply power to the pulse light sterilization component 420, so that the pulse lamp body 422 can work normally to emit strong light.

[0128] In some embodiments, in combination Figure 2 , Fig.10 and Fig.13 As shown, the lamp housing 421 includes: a lamp holder 4213 and a lamp shade 4214. The lamp holder 4213 is arranged opposite to the evaporator 200 and the length direction of the lamp holder 4213 extends along the length direction of the evaporator 200. The lamp shade 4214 is arranged on the side of the lamp holder 4213 facing away from the evaporator 200 and cooperates with the lamp holder 4213 to define a accommodating cavity 4211. At least one of the lamp holder 4213 and the lamp shade 4214 is provided with a light-transmitting hole 4212. Among them, by setting the lamp housing 421 to include a lamp holder 4213 and a lamp shade 4214, and the lamp shade 4214 is covered on the side of the lamp holder 4213 facing away from the evaporator 200 and cooperates with the lamp holder 4213 to define the accommodating cavity 4211, the difficulty of molding the lamp housing 421 and the accommodating cavity 4211 is reduced, thereby facilitating the arrangement of the pulse lamp body 422 in the accommodating cavity 4211; by setting the lamp holder 4213 opposite to the evaporator 200 and setting the length direction of the lamp holder 4213 to extend along the length direction of the evaporator 200, while ensuring that the pulse light sterilization component 420 can be arranged directly facing the evaporator 200, the area of ​​the pulse light sterilization component 420 facing the evaporator 200 can also be increased, thereby improving the sterilization effect of the pulse light sterilization component 420.

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

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

[0131] In some embodiments, the lampshade 4214 and the lamp holder 4213 are detachably connected to facilitate the installation of the pulse lamp body 422, while also reducing the difficulty of assembling and disassembling the pulse light sterilization component 420 and increasing the convenience of maintaining the pulse light sterilization component 420.

[0132] Optionally, the lampshade 4214 and the lamp holder 4213 are snap-connected to achieve a detachable connection between the lampshade 4214 and the lamp holder 4213 , thereby reducing the difficulty of assembling and disassembling the pulse light sterilization component 420 .

[0133] In some embodiments, Fig.14 As shown, the lamp holder 4213 is provided with a plurality of second clip holes 4218, and the lamp shade 4214 is provided with a plurality of second clips matching with the second clip holes 4218, and the second clips are clipped and matched in the second clip holes 4218 to realize the clip connection between the lamp shade 4214 and the lamp holder 4213, that is, to realize the detachable connection between the lamp shade 4214 and the lamp holder 4213, thereby reducing the difficulty of assembly and disassembly of the pulse light sterilization component 420.

[0134] Of course, in some other embodiments, a plurality of second snap holes 4218 are provided on the lampshade 4214, and a second snap buckle matching the second snap holes 4218 is provided on the lamp holder 4213, so that the lampshade 4214 and the lamp holder 4213 can be snap-connected, and this application does not impose any specific restrictions.

[0147] In the description of the present utility model, features defined as “first”, “second”, and “third” may explicitly or implicitly include one or more such features, and are used to distinguish and describe the features, without any distinction of order or importance.

[0148] In some embodiments, Fig.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 parts 411 mainly release a large number of free electrons after the negative ion sterilization component 410 is powered on, and the free electrons are captured by oxygen molecules in the air, thereby generating air negative oxygen ions, i.e., negative ions. After the generated negative ions come into contact with bacteria, viruses, etc., they can destroy the molecular protein structure of bacteria, viruses, etc., change their structure, reverse the polarity of proteins, or transfer energy, thereby killing bacteria, viruses, etc., and achieving the purpose of sterilization by using the negative ion sterilization component 410.

[0149] At the same time, by providing a plurality of negative ion release parts 411 , 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 improving 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 amount of free electrons after the negative ion sterilization component 410 is powered on, thereby ensuring the working performance of the negative ion sterilization component 410.

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

[0152] Alternatively, if Fig.17 As shown, the number of negative ion release parts 411 is equal to 3, and the three negative ion release parts 411 are arranged at intervals. The three negative ion release parts 411 cooperate to increase the number of negative ions generated by the negative ion sterilization component 410 and the negative ion generation efficiency of the negative ion sterilization component 410, while also reducing the manufacturing cost of the negative ion sterilization component 410 and simplifying the structure of the negative ion sterilization component 410.

[0153] Alternatively, if Fig.17 As shown, the three negative ion release parts 411 form a triangular structure. Through experiments and theoretical simulations, it is found that by setting up three negative ion release parts 411 and forming a triangular structure, the sterilization effect is best, and the sterilization capacity of the negative ion sterilization component 410 can reach more than 99.5%.

[0154] In some embodiments, in combination 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 channel 180 is defined between the air outlet frame 170 and the volute tongue 160, the air outlet channel 180 is connected to the air outlet 120 and the air duct 130, and the negative ion sterilization component 410 is arranged on the air outlet frame 170. In this way, while the negative ion sterilization component 410 is supported by the air outlet frame 170, the negative ion sterilization component 410 can also be arranged close to the air outlet 120, so that the negative ion sterilization component 410 can be used to sterilize the air flowing through it, and the negative ions generated by the negative ion sterilization component 410 can flow through the room through the air outlet 120, so that the negative ion sterilization component 410 can be used to sterilize the indoor air.

[0155] It is worth noting that by using the air outlet frame 170 to support the negative ion sterilization component 410 , the difficulty of fixing the negative ion sterilization component 410 can be reduced, thereby improving the position stability of the negative ion sterilization component 410 to ensure the working performance of the negative ion sterilization component 410 .

[0157] At the same time, by arranging 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 shield the negative ion sterilization component 410 to prevent the user from directly observing the negative ion sterilization component 410, thereby improving the aesthetics of the air conditioning indoor unit 1000.

[0160] Optionally, the negative ion sterilization component 410 is plugged into the chassis 140 to reduce the difficulty of connecting the negative ion sterilization component 410 with the chassis 140, thereby reducing the difficulty of assembling the negative ion sterilization component 410 and improving the assembly efficiency.

[0161] In some embodiments, in combination Fig.17 , Fig.19 and Fig. 20 As shown, the negative ion sterilization component 410 includes a mounting seat 412 and a mounting cover 413. The mounting cover 413 is arranged on the mounting seat 412 and defines a matching cavity between the mounting seat 412. A through hole is formed on the mounting cover 413 and penetrates in the thickness direction. The through hole is connected to the matching cavity. A plurality of negative ion release parts 411 are arranged in the matching cavity. One end of the negative ion release part 411 extends out of the matching cavity through the through hole to ensure the working performance of the negative ion release part 411.

[0162] At the same time, by configuring the negative ion sterilization component 410 to include a mounting seat 412 and a mounting cover 413, the molding difficulty of the negative ion sterilization component 410 can be reduced, and the mounting seat 412 and the mounting cover 413 can be used to cooperate to limit the position of the negative ion release portion 411, thereby improving the position stability of the negative ion release portion 411.

[0163] In some embodiments, Fig. 20 As shown, the negative ion sterilization component 410 includes a conductive part 414, and the conductive part 414 is formed with a plurality of extended legs, and each negative ion release part 411 is arranged on the extended legs one by one. This facilitates the supply of 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 multiple extended legs, multiple negative ion release parts 411 can be powered by one conductive part 414, which facilitates the control of the operation and stop of the negative ion release part 411, and enables the multiple negative ion release parts 411 to be connected in parallel with each other, so that the multiple negative ion release parts 411 can work independently without affecting each other.

[0165] In some embodiments, the negative ion sterilization component 410 includes a plurality of negative ion sterilization components 410, and the plurality of negative ion sterilization components 410 are arranged at intervals 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.

[0167] At the same time, by arranging the negative ion sterilization component 410 relative to the space between two adjacent air guide blades 192, the negative ion sterilization component 410 can be located between two adjacent air guide blades 192, avoiding the negative ion sterilization component 410 from being arranged close to the air guide blades 192, thereby avoiding the negative ion sterilization component 410 from interfering with the rotation of the air guide blades 192, thereby ensuring the working performance of the air guide blades 192, and because the air guide blades 192 are generally made of plastic material, the above arrangement can also prevent the negative ions generated by the negative ion sterilization component 410 from being absorbed by the air guide blades 192, thereby ensuring the sterilization ability of the negative ion sterilization component 410.

[0168] In some embodiments, the negative ion sterilization component 410 is directly opposite the middle of the space between two adjacent air guide blades 192, so that the distance between the negative ion sterilization component 410 and the two adjacent air guide blades 192 is consistent, so as to further avoid the negative ion sterilization component 410 being set close to the air guide blades 192, thereby avoiding the negative ions generated by the negative ion sterilization component 410 from being absorbed by the air guide blades 192, thereby improving the sterilization ability of the negative ion sterilization component 410.
