DETAILED DESCRIPTION

[0059] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0060] The air conditioner indoor unit 1000 according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0061] As shown in Figures 1, 2 and 3, an air-conditioning indoor unit 1000 according to an embodiment of the present application includes: a casing assembly 100, an evaporator 200, a fan 300 and a sterilization device 400.

[0062] As shown in Figures 1 and 3 , the housing assembly 100 includes an air inlet 110, an air outlet 120, and an air duct 130. The air duct 130 connects the air inlet 110 and the air outlet 120. 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. The air is then delivered to the room through the air outlet 120, thereby regulating the indoor air temperature, improving indoor comfort, and ensuring the operating performance of the air conditioner indoor unit 1000.

[0063] As shown in Figure 3, the evaporator 200 and the fan 300 are both located within the air duct 130, with the fan 300 positioned between the evaporator 200 and the air outlet 120 in the direction of airflow. In other words, the evaporator 200 and the fan 300 are both located within 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 this order.

[0064] 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.

[0065] 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.

[0066] As shown in Figures 1, 2 and 3, 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.

[0067] Among them, by setting up a negative ion sterilization component 410, a pulse light sterilization component 420 and a power supply box 430, and setting 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.

[0068] Among them, when the power supply box 430 is used to power the negative ion sterilization component 410, the negative ion sterilization component 410 can produce negative ions, which can combine with dust, bacteria, viruses and other microorganisms in the air to change their structure, thereby achieving the purpose of sterilization and purifying the air; when the power supply box 430 is used to power the pulse light sterilization component 420, the pulse light sterilization component 420 can emit sterilization light, such as ultraviolet light, infrared light, etc., 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.

[0069] 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.

[0070] 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 negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430 can be assembled separately during assembly, 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 to be maintained 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 maintaining the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430.

[0071] That is to say, the present application can reduce the manufacturing difficulty of the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430 by independently arranging the negative ion sterilization component 410, the pulse light sterilization component 420 and the power supply box 430 in the casing component 100. Secondly, 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. Thirdly, 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.

[0072] 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.

[0073] As can be seen from the above structure, the air-conditioning indoor unit 1000 of the embodiment of the present application is equipped with a negative ion sterilization component 410, a pulse light sterilization component 420 and a power supply box 430, so that the air-conditioning indoor unit 1000 can emit sterilization light and release ions that can kill bacteria, thereby achieving the purpose of two-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.

[0074] 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, and 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.

[0075] It can be understood that compared with the existing technology, 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. In this way, while the air-conditioning indoor unit 1000 can achieve two-stage purification and sterilization, it can also reduce the maintenance difficulty of the air-conditioning indoor unit 1000 and help improve the maintenance efficiency of the air-conditioning indoor unit 1000.

[0076] In some embodiments, as shown in Figures 5 and 6, 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. This enables the power supply box 430 to 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 difficulty of controlling the negative ion sterilization component 410 and the pulse light sterilization component 420. In this way, when power cannot be supplied 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, thereby reducing the difficulty of maintenance.

[0077] At the same time, the above-mentioned setting can also 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 assembly difficulty of the air-conditioning indoor unit 1000, and reducing the manufacturing cost of the air-conditioning indoor unit 1000.

[0078] 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.

[0079] In some embodiments, as shown in conjunction with Figures 5 and 6 , a separating rib 4311 is provided within the box body 431. The separating 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. This allows both the first circuit board 432 and the second circuit board 433 to be disposed within the box body 431 while also separating the first circuit board 432 and the second circuit board 433 from each other, thereby preventing interference between the first circuit board 432 and the second circuit board 433, 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.

[0080] In some embodiments, as shown in Figures 5 and 6, 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 arranged in the first chamber 4312 and the second circuit board 433 can be arranged in the second chamber 4313, the difficulty of installing the first circuit board 432 and the second circuit board 433 can be further reduced. 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.

[0081] 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. The height of the sealing glue in the first chamber 4312 is different from the height of the sealing glue in the second chamber 4313. The sealing glue not only protects the first circuit board 432 and the second circuit board 433, but also secures the first circuit board 432 and the second circuit board 433, thereby extending the service life of the first circuit board 432 and the second circuit board 433 and preventing the first circuit board 432 and the second circuit board 433 from shaking within the box body 431.

[0082] 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.

[0083] 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 making it easier for users to distinguish between the first chamber 4312 and the second chamber 4313, that is, to ensure that the first circuit board 432 and the second circuit board 433 are sealed with glue, and users can quickly and accurately locate the installation positions of the first circuit board 432 and the second circuit board 433.

[0084] In other embodiments, the height of the sealing compound in the first chamber 4312 is smaller than the height of the sealing compound in the second chamber 4313 , so that the height of the sealing compound in the first chamber 4312 is not equal to the height of the sealing compound in the second chamber 4313 .

[0085] 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 sealing glue in the first chamber 4312 to be smaller than the height of the sealing glue in the second chamber 4313, the amount of sealing glue used in the first chamber 4312 can also be reduced, thereby reducing the sealing glue 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.

[0086] 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.

[0087] In some embodiments, as shown in conjunction with FIG5 and FIG6 , the box body 431 has a first wire outlet 4314 and a second wire outlet 4315. 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 extends through the first wire outlet 4314 to connect to the first wire. One end of the second lead wire is connected to the second circuit board 433, and the other end extends through the second wire outlet 4315 to connect to the second wire. This achieves electrical connection between the first circuit board 432 and the negative ion sterilization assembly 410, and between the second circuit board 433 and the pulse light sterilization assembly 420. This facilitates powering the negative ion sterilization assembly 410 and the pulse light sterilization assembly 420 using the power supply box 430, thereby ensuring the operating performance of the negative ion sterilization assembly 410 and the pulse light sterilization assembly 420, and reducing the difficulty of connecting the power supply box 430 to the negative ion sterilization assembly 410 and the pulse light sterilization assembly 420.

[0088] In some embodiments, as shown in Figures 5 and 6, the power supply box 430 further includes a protective shell 434, which wraps around the outside of the box body 431 and exposes the first wire outlet 4314 and the second wire outlet 4315. This prevents the protective shell 434 from obstructing the connection between the first lead wire and the first wire and the connection between the second lead wire and the second wire, while also protecting the box body 431, thereby extending the service life of the box body 431 and reducing the cost of using the power supply box 430.

[0089] In some embodiments, the protective shell 434 is a metal shell. The metal shell not only provides a certain structural strength for the protective shell 434, thereby facilitating its use to protect the box body 431 and improving the protective performance of the protective shell 434, but also prevents the first circuit board 432 and the second circuit board 433 from bursting through the potting compound and splashing onto other components, thereby avoiding large-scale fires and potential safety hazards, thereby improving the performance of the power supply box 430.

[0090] 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.

[0091] In some embodiments, as shown in Figures 5 and 6 , 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 that cooperates with the connecting protrusion 4341. This 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 that cooperates with the connecting protrusion 4341, and the connecting protrusion 4341 is limited and fits in the limiting hole to achieve fixed connection between 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 that cooperates with the connecting protrusion 4341. In this way, while achieving fixed connection between the two relative parts of the protective shell 434, it can also improve the structural strength of the protective shell 434 and reduce the difficulty of molding the protective shell 434.

[0092] The fastening connectors mentioned here may be fastening bolts or fastening screws, etc., so as to realize the assembly connection of the protective shell 434 by using the fastening connectors.

[0093] In some embodiments, as shown in FIG3 , the negative ion sterilization assembly 410 is located downstream of the fan 300 in the direction of airflow, and the pulse light sterilization assembly 420 is located between the evaporator 200 and the fan 300 in the direction of airflow. By placing the negative ion sterilization assembly 410 downstream of the fan 300, the negative ion sterilization assembly 410 can be placed close to the air outlet 120. In this way, while the negative ion sterilization assembly 410 sterilizes the air flowing through it, negative ions can also flow through the room with the air, so that the negative ion sterilization assembly 410 can be used to settle particulate matter such as PM2.5 in the room, thereby removing dust and improving indoor air quality to ensure a better user experience.

[0094] At the same time, in the direction of airflow, by setting the pulse light sterilization component 420 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 using the pulse light sterilization component 420 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 realizing clean air outlet of the air-conditioning indoor unit 1000.

[0095] 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 of the indoor space to deteriorate. Therefore, this 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.

[0096] 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 airflow and arranging the pulse light sterilization component 420 to be located between the evaporator 200 and the fan 300 in the direction of the airflow, the negative ion sterilization component 410 and the pulse light sterilization component 420 can be arranged in sequence in the direction of the airflow, 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.

[0097] In some embodiments, as shown in conjunction with Figures 2, 3, and 4, the housing assembly 100 includes: a base plate 140 and an evaporator bracket 150. The evaporator bracket 150 is connected to the base plate 140, and one end of the evaporator 200 is connected to the evaporator bracket 150. By connecting the evaporator bracket 150 to the base plate 140, the base plate 140 can be used to support the evaporator bracket 150, thereby improving the positional stability of the evaporator bracket 150. Thus, 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, thereby improving the positional stability of the evaporator 200 and ensuring the operating performance of the evaporator 200. Furthermore, the above arrangement can also stabilize the overall structure of the air conditioner indoor unit 1000.

[0098] Optionally, as shown in Figures 7, 8, and 11, the power supply box 430 and the pulse light sterilization assembly 420 are both mounted on the evaporator bracket 150. This allows the evaporator bracket 150 to support the power supply box 430 and the pulse light sterilization assembly 420, thereby improving their positional stability and ensuring their operating performance.

[0099] 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 set close to the pulse light sterilization component 420, so as 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, reducing the difficulty of connecting the power supply box 430 and the pulse light sterilization component 420.

[0100] In addition, the above setting can also allow the pulse light sterilization component 420 to be set close to the evaporator 200, so that the pulse light sterilization component 420 can be used to sterilize the evaporator 200, thereby ensuring the cleanliness of the air flow after passing through the evaporator 200 and achieving clean air outlet of the air conditioner indoor unit 1000.

[0101] In some embodiments, as shown in Figures 2, 9 and 10, the power supply box 430 is disposed on the side of the evaporator bracket 150 facing away from the evaporator 200, and the pulse light sterilization component 420 is disposed 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 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.

[0102] At the same time, through the above-mentioned arrangement, the power supply box 430 and the pulse light sterilization component 420 can be arranged on opposite sides of the evaporator bracket 150 (as shown in Figures 11 and 12) to avoid interference between the power supply box 430 and the pulse light sterilization component 420 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 can be reduced.

[0103] 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 via a first fastener, and the first fastener is inserted through the first connection hole and the first mating hole. This means that when the evaporator bracket 150 is provided with a first connection hole, the power supply box 430 is also provided with a first mating hole; when the power supply box 430 is provided with a first connection hole, the evaporator bracket 150 is also provided with a first mating hole. In this way, when the first fastener is inserted through the first connection hole and the first mating hole, the power supply box 430 can be fixed to the evaporator bracket 150 via the first fastener, thereby achieving a fixed connection between the power supply box 430 and the evaporator bracket 150. This facilitates the use of the evaporator bracket 150 to support the power supply box 430, thereby improving the positional stability of the power supply box 430 and reducing the difficulty of connecting the power supply box 430 to the evaporator bracket 150.

[0104] Optionally, the first fastener is a fastening bolt or a fastening screw, etc., so that the first fastener is used to achieve a fixed connection between the power supply box 430 and the evaporator bracket 150.

[0105] 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.

[0106] In some embodiments, as shown in conjunction with Figures 2, 7, and 8, one end of the pulse light sterilization assembly 420 is connected to the evaporator bracket 150, and the other end is suspended within the air duct 130. This allows the pulse light sterilization assembly 420 to be positioned within the evaporator bracket 150 while also being positioned directly opposite the evaporator 200. This facilitates the use of the pulse light sterilization assembly 420 to sterilize the evaporator 200, preventing residual bacteria from forming on the evaporator 200 and ensuring the cleanliness of the air flowing through the evaporator 200.

[0107] At the same time, the above-mentioned 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.

[0108] 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 clip to be clipped and connected to 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 clip to be clipped and connected to 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.

[0109] Among them, when the 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 clip to be clipped and connected to the evaporator bracket 150, while achieving a fixed connection between the pulse light sterilization component 420 and the evaporator bracket 150, it can also increase the connection strength between the pulse light sterilization component 420 and the evaporator bracket 150 and reduce the difficulty of connecting the pulse light sterilization component 420 and the evaporator bracket 150.

[0110] 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-fit ​​component to be snap-fitted to the evaporator bracket 150, the snap-fit ​​component can be first used to achieve the snap-fitting of one end of the pulse light sterilization component 420 with 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.

[0111] 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, thereby reducing the difficulty of assembling and disassembling the pulse light sterilization component 420, thereby reducing the difficulty of maintaining the pulse light sterilization component 420.

[0112] Optionally, the second fastener is a fastening bolt or a fastening screw, so that the second fastener can be used to achieve a fixed connection between the pulse light sterilization component 420 and the evaporator bracket 150.

[0113] In some embodiments, one of the ends of the evaporator bracket 150 and the pulse light sterilization component 420 is provided with a second connection hole and the other is provided with a second matching hole, and a second fastener is passed through the second connection 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 achieving a fixed connection between the evaporator bracket 150 and the pulse light sterilization component 420.

[0114] Optionally, the snap-fit ​​component is a first snap, which is provided at one end of the pulse light sterilization component 420. The evaporator bracket 150 is provided with a first snap hole that cooperates with the first snap, and the first snap is snapped into the first snap hole to realize the snap connection between the pulse light sterilization component 420 and the evaporator bracket 150, thereby realizing the pulse light sterilization component 420 being arranged on the evaporator bracket 150.

[0115] In some embodiments, there are multiple first clips, and the multiple first clips are spaced apart at one end of the pulse light sterilization component 420. The evaporator bracket 150 is provided with multiple first clip holes that cooperate with the first clips. In this way, while achieving a fixed connection between the pulse light sterilization component 420 and the evaporator bracket 150, it can also improve the connection strength of the pulse light sterilization component 420 to the evaporator bracket 150 to ensure the position stability of the pulse light sterilization component 420.

[0116] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0117] Of course, in some other embodiments, a first buckle may be provided on the evaporator bracket 150, and a first clip hole cooperating with the first buckle may be provided on one end of the pulse light sterilization component 420. In this way, the pulse light sterilization component 420 may be snap-connected to the evaporator bracket 150, and this application does not impose any specific restrictions.

[0118] 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 placed 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 positional 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.

[0119] In some embodiments, as shown in Figure 13, 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, which is convenient for using 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.

[0120] At the same time, by arranging multiple light-transmitting holes 4212 connected to 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 multiple light-transmitting holes 4212 and irradiate 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.

[0121] 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.

[0122] It should be noted that the “plurality” mentioned above refers to two or more.

[0123] In some embodiments, the number of light-transmitting holes 4212 is two, three, or more. Simulation experiments have shown that by employing the aforementioned pulsed light sterilization assembly 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 enhancing the user experience.

[0124] 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 the air-conditioning indoor unit 1000, thereby improving the sterilization effect of the pulse light sterilization component 420.

[0125] 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.

[0126] 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 microbial body, causing DNA chain breakage, cross-linking rupture of nucleic acid and protein, 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.

[0127] 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 supply of the air-conditioning indoor unit 1000, and improving the user experience.

[0128] 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.

[0129] In some embodiments, in combination with Figures 2, 10 and 13, the lamp housing 421 includes: a lamp holder 4213 and a lampshade 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 lampshade 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 a accommodating cavity 4211, and at least one of the lamp holder 4213 and the lampshade 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 lampshade 4214, and the lampshade 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 set 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.

[0130] At the same time, by providing a light-transmitting hole 4212 in at least one of the lamp holder 4213 and the lampshade 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 the air-conditioning indoor unit 1000, thereby realizing the sterilization effect of the pulse light sterilization component 420.

[0131] In some embodiments, the pulse lamp body 422 extends along the length direction of the lamp holder 4213 and is arranged 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 arranged in the lamp housing 421.

[0132] 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.

[0133] Optionally, the lampshade 4214 and the lamp holder 4213 are snap-connected, thereby achieving 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 .

[0134] In some embodiments, as shown in FIG14 , a plurality of second snap holes 4218 are provided on the lamp holder 4213, and a plurality of second snap buckles matching the second snap holes 4218 are provided on the lamp shade 4214. The second snap buckles are snap-fitted into the second snap holes 4218 to achieve a snap-fit ​​connection between the lamp shade 4214 and the lamp holder 4213, that is, to achieve a detachable connection between the lamp shade 4214 and the lamp holder 4213, thereby reducing the difficulty of assembling and disassembling the pulse light sterilization component 420.

[0135] 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.

[0136] In some embodiments, as shown in conjunction with Figures 13 and 14 , at least a portion of the light-transmitting holes 4212 are first light-transmitting holes 4215, and multiple first light-transmitting holes 4215 are provided on the lamp holder 4213 and spaced apart along the length of the lamp holder 4213. In other words, the lamp holder 4213 is provided with multiple first light-transmitting holes 4215, and the multiple first light-transmitting holes 4215 are spaced apart along the length of the lamp holder 4213, so that the lamp housing 421 is provided with multiple light-transmitting holes 4212 that communicate with the accommodating cavity 4211. This ensures that the strong light emitted by the pulse lamp body 422 can reach the air conditioner indoor unit 1000, achieving the sterilization effect of the pulse light sterilization assembly 420.

[0137] At the same time, since the pulse lamp body 422 extends along the length direction of the lamp holder 4213, by arranging multiple first light-transmitting holes 4215 to be spaced apart in the length direction of the lamp holder 4213, it can be ensured that the multiple first light-transmitting holes 4215 can all face the pulse lamp body 422, so as to increase the illumination range of the pulse lamp body 422, thereby increasing the processing area of ​​the pulse light sterilization component 420 for sterilization and disinfection, and improving the working performance of the pulse light sterilization component 420.

[0138] In some embodiments, the number of the first light-transmitting holes 4215 can be two, three, or more.

[0139] In some embodiments, as shown in Figures 13 and 14, two first light-transmitting holes 4215 are provided on a side wall of the lamp holder 4213 facing the lampshade 4214, and the two first light-transmitting holes 4215 are arranged at intervals in the length direction of the lamp holder 4213. In this way, while multiple first light-transmitting holes 4215 are provided on the lamp holder 4213, the structural strength of the lamp holder 4213 can be ensured, thereby ensuring the structural strength of the lamp housing 421, so that the lamp housing 421 can be used to support and protect the pulse lamp body 422, so as to improve the working performance of the pulse lamp body 422.

[0140] In some embodiments, as shown in FIG14 , at least one first light-transmitting hole 4215 is a rectangular hole. Rectangular holes have a large light-transmitting area and are easy to manufacture, thereby increasing the illumination range of the pulse lamp body 422 while reducing the difficulty of manufacturing the lamp holder 4213.

[0141] In some embodiments, as shown in conjunction with Figures 13, 15, and 16, at least a portion of the light-transmitting holes 4212 are second light-transmitting holes 4216, and a plurality of second light-transmitting holes 4216 are provided on the lampshade 4214 and spaced apart along the length of the lampshade 4214. In other words, the lampshade 4214 is provided with a plurality of second light-transmitting holes 4216, and the plurality of second light-transmitting holes 4216 are spaced apart along the length of the lampshade 4214, thereby providing a plurality of light-transmitting holes 4212 in communication with the accommodating cavity 4211 on the lamp housing 421, thereby ensuring that the strong light emitted by the pulse lamp body 422 can illuminate the air conditioner indoor unit 1000.

[0142] At the same time, by arranging multiple second light-transmitting holes 4216 to be spaced apart in the length direction of the lampshade 4214, it can be ensured that the multiple second light-transmitting holes 4216 can all face the pulse lamp body 422, so as to increase the illumination range of the pulse lamp body 422, thereby increasing the processing area of ​​the pulse light sterilization component 420 for sterilization and disinfection, and improving the working performance of the pulse light sterilization component 420.

[0143] In some embodiments, the number of the second light-transmitting holes 4216 can be two, three, or more.

[0144] In some embodiments, in combination with Figures 13, 15 and 16, the lampshade 4214 includes a plurality of lampshades 4214, and the plurality of lampshades 4214 are spaced apart in the length direction of the lamp housing 421, and at least one lampshade 4214 located at one end of the length direction of the lamp housing 421 is spaced apart from the lamp holder 4213 to form a second light-transmitting hole 4216 between two adjacent lampshades 4214 and between the lampshade 4214 and the lamp holder 4213, thereby providing a plurality of second light-transmitting holes 4216 on the lampshade 4214 to reduce the difficulty of forming the plurality of second light-transmitting holes 4216.

[0145] Optionally, the lampshade 4214 is made of an insulating, aging-resistant and high-temperature resistant flexible material, for example, a rubber material, so that the lampshade 4214 has insulating, buffering and sealing functions to improve the installation stability of the pulse lamp body 422 and ensure the safe use of the pulse lamp body 422.

[0146] In some embodiments, as shown in Figures 13, 15, and 16, at least one light-transmitting hole 4212 is a third light-transmitting hole 4217, which is located at one end of the lamp holder 4213 in the longitudinal direction. At least one second light-transmitting hole 4216 is located at one end of the lampshade 4214 in the longitudinal direction, opposite to and connected to the third light-transmitting hole 4217. In other words, the lamp holder 4213 is provided with a plurality of first light-transmitting holes 4215 and third light-transmitting holes 4217, with the plurality of first light-transmitting holes 4215 spaced apart along the longitudinal direction of the lamp holder 4213. The third light-transmitting hole 4217 is located at one end of the lamp holder 4213 in the longitudinal direction, opposite to and connected to the second light-transmitting hole 4216 located at one end of the lampshade 4214 in the longitudinal direction. This allows the pulse lamp body 422 to emit light outward in both the circumferential and axial directions, thereby sterilizing and disinfecting the interior of the air conditioner indoor unit 1000.

[0147] In summary, the present application arranges the multiple light-transmitting holes 4212 to include multiple first light-transmitting holes 4215, multiple second light-transmitting holes 4216 and third light-transmitting holes 4217, so that the pulse light sterilization component 420 can perform multi-directional sterilization on the interior of the air-conditioning indoor unit 1000, increase the illumination range of the pulse lamp body 422, and thereby improve the sterilization effect of the pulse light sterilization component 420.

[0148] In the description of this application, features defined as "first", "second" and "third" may explicitly or implicitly include one or more such features, and are used to distinguish and describe features, without any distinction in order or importance.

[0149] In some embodiments, as shown in FIG17 , the negative ion sterilization assembly 410 includes multiple negative ion release sections 411, which are arranged at intervals. The negative ion release sections 411 primarily release a large number of free electrons when the negative ion sterilization assembly 410 is powered on. These free electrons are captured by oxygen molecules in the air, thereby generating negative oxygen ions (i.e., negative ions) in the air. Upon contact with bacteria, viruses, etc., the generated negative ions can destroy the molecular protein structures of the bacteria, viruses, etc., causing structural changes, protein polarity reversal, or energy transfer, thereby killing the bacteria, viruses, etc., thereby achieving the sterilization purpose of the negative ion sterilization assembly 410.

[0150] 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 .

[0151] In some embodiments, the negative ion release portion 411 is made of materials such as carbon fiber and tungsten wire to ensure that the negative ion sterilization component 410 can release a large amount of free electrons after being energized, thereby ensuring the working performance of the negative ion sterilization component 410.

[0152] In some embodiments, as shown in FIG17 , the number of the negative ion releasing parts 411 is greater than or equal to 3, so as 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 .

[0153] Optionally, as shown in Figure 17, 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 improve 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.

[0154] Optionally, as shown in Figure 17, three negative ion release parts 411 are arranged to form a triangular structure. Through experiments and theoretical simulations, it is found that by setting three negative ion release parts 411 and enclosing the three negative ion release parts 411 to form 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%.

[0155] In some embodiments, as shown in conjunction with Figures 2 and 3, the housing assembly 100 further includes: a volute 160 and an air outlet frame 170. An air outlet channel 180 is defined between the air outlet frame 170 and the volute 160. The air outlet channel 180 connects 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 the air outlet frame 170 is used to support the negative ion sterilization component 410, the negative ion sterilization component 410 can also be disposed close to the air outlet 120, thereby facilitating the use of the negative ion sterilization component 410 to sterilize the air flowing therethrough, and allowing the negative ions generated by the negative ion sterilization component 410 to flow into the room through the air outlet 120, thereby facilitating the use of the negative ion sterilization component 410 to sterilize the indoor air.

[0156] It is worth noting that using the air outlet frame 170 to support the negative ion sterilization component 410 can reduce the difficulty of fixing the negative ion sterilization component 410, thereby improving the position stability of the negative ion sterilization component 410 and ensuring the working performance of the negative ion sterilization component 410.

[0157] In some embodiments, as shown in conjunction with Figures 3, 17, and 18, the air outlet frame 170 defines an installation cavity 171 that opens toward the air outlet passage 180. The negative ion sterilization assembly 410 is disposed within the installation cavity 171, with multiple negative ion releasers 411 exposed from the opening. This allows the multiple negative ion releasers 411 to be disposed within the air outlet passage 180, thereby facilitating the use of the negative ion sterilization assembly 410 to sterilize the air flowing through the air outlet passage 180 and allowing negative ions to flow with the air into the room, thereby facilitating the use of the negative ion sterilization assembly 410 to sterilize the indoor air.

[0158] 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 intuitively observing the negative ion sterilization component 410, thereby improving the aesthetics of the air-conditioning indoor unit 1000.

[0159] In some embodiments, as shown in Figures 3, 17, and 18, an 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 a mounting cavity 171. The negative ion sterilization assembly 410 is connected to the chassis 140 and is located within the mounting cavity 171. This allows the chassis 140 to support the negative ion sterilization assembly 410, thereby improving the positional stability of the negative ion sterilization assembly 410.

[0160] In some embodiments, the negative ion sterilization component 410 can be pre-installed on the chassis 140 in advance and can be made into an insert when the mold is opened, so that it can be selected at any time during subsequent selection.

[0161] 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 to the chassis 140, thereby reducing the difficulty of assembling the negative ion sterilization component 410 and improving assembly efficiency.

[0162] In some embodiments, in combination with Figures 17, 19 and 20, the negative ion sterilization component 410 includes a mounting base 412 and a mounting cover 413. The mounting cover 413 is arranged on the mounting base 412 and defines a matching cavity between the mounting base 412. A through hole is formed on the mounting cover 413 and passes through in the thickness direction. The through hole connects 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.

[0163] At the same time, by configuring the negative ion sterilization component 410 to include a mounting seat 412 and a mounting cover 413, the difficulty of molding the negative ion sterilization component 410 can be reduced, and it is convenient to utilize the mounting seat 412 and the mounting cover 413 to cooperate in limiting the position of the negative ion release part 411, thereby improving the position stability of the negative ion release part 411.

[0164] In some embodiments, as shown in FIG20 , the negative ion sterilization assembly 410 includes a conductive portion 414 having a plurality of extended legs, with each negative ion release portion 411 disposed one-to-one on the extended legs. This facilitates supplying power to the negative ion release portion 411, enabling the negative ion sterilization assembly 410 to generate negative ions when powered, thereby ensuring the performance of the negative ion sterilization assembly 410.

[0165] At the same time, by setting up 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, and the multiple negative ion release parts 411 work independently without affecting each other.

[0166] In some embodiments, the negative ion sterilization assembly 410 includes multiple negative ion sterilization assemblies 410, which are spaced apart on the chassis 140. The multiple negative ion sterilization assemblies 410 can enhance the sterilization capability of the air conditioner indoor unit 1000 and make the negative ions generated by the air conditioner indoor unit 1000 more evenly distributed, thereby improving the purification capability of the air conditioner indoor unit 1000.

[0167] In some embodiments, as shown in Figures 7, 8, and 10, an air guide assembly 190 is provided within the air outlet duct 180. The air guide assembly 190 includes a connecting rod 191 and a plurality of air guide vanes 192. The plurality of air guide vanes 192 are spaced apart along the length of the connecting rod 191, and the negative ion sterilization assembly 410 is positioned opposite the space between two adjacent air guide vanes 192. The provision of the air guide assembly 190 facilitates the use of the air guide assembly 190 to guide the flow direction of the air within the air outlet duct 180, thereby achieving a wide range of air outlet for the air conditioner indoor unit 1000 and ensuring the operating performance of the air conditioner indoor unit 1000.

[0168] At the same time, by arranging the negative ion sterilization component 410 relative to the space between two adjacent guide blades 192, the negative ion sterilization component 410 can be located between the two adjacent guide blades 192, avoiding the negative ion sterilization component 410 from being arranged close to the guide blades 192, thereby avoiding the negative ion sterilization component 410 from interfering with the rotation of the guide blades 192, ensuring the working performance of the guide blades 192, and because the 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 guide blades 192, thereby ensuring the sterilization ability of the negative ion sterilization component 410.

[0169] 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 preventing 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.
