The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0067] The following disclosure provides many different embodiments, or examples, for implementing different structures of the application. For the purpose of simplifying the present application, the components and arrangements of the specific examples are described. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application can repeatedly refer to the reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0068] The sterilization device 100 for the air conditioner 1000 according to the embodiments of the present application is described below with reference to the accompanying drawings.

[0069] As shown in Figure 1 and Figure 2 , the air conditioner 1000 has a fresh air module 700 with a fresh air outlet, and the sterilization device 100 is adapted to be provided at the fresh air outlet (in combination with Figure 13 ). The sterilization device 100 can sterilize and disinfect the airflow at the fresh air outlet, play a role in purifying the air, and make the air introduced into the room fresh, clean and safe. Therefore, the air conditioner 1000 can have a medical fresh air function, thereby improving the comfort experience of the user. In comparison with some air conditioners 1000, in the case of abnormal weather and rampant viruses, long-term use can cause the indoor air to be turbid and not to circulate well, making people's living experience worse and easily getting air conditioning disease, or causing the virus to spread rapidly in the air, which does not meet the concept of healthy life. In the present application, the sterilization device 100 is applied to the air conditioner 1000, which can meet the flowability of the air in the room and the cleanliness and safety of the air breathed in the case of special epidemic situation and the like.

[0070] As shown in Figure 1 , Figure 2 and Figure 6 , the sterilization device 100 for the air conditioner 1000 according to the embodiments of the present application comprises a mounting seat 1, an air duct piece 2, a pull-out assembly 3 and a sterilization and disinfection assembly 4. The mounting seat 1 is formed with an air inlet 10 adapted to communicate with the fresh air outlet. The air duct piece 2 is provided on the mounting seat 1 and defines a sterilization air duct 20 communicating with the air inlet 10. The pull-out assembly 3 is slidably connected with the mounting seat 1 and is oppositely arranged with the air duct piece 2. The side wall of the pull-out assembly 3 is provided with an air outlet 30 communicating with the sterilization air duct 20. The sterilization and disinfection assembly 4 comprises an ultraviolet lamp 41 and a photocatalyst net 42. The sterilization and disinfection assembly 4 is provided on the pull-out assembly 3 and located at the outlet of the sterilization air duct 20.

[0071] By placing the sterilization and disinfection component 4 at the fresh air outlet, the ultraviolet light emitted by the ultraviolet lamp 41 at an appropriate wavelength, under the action of the photocatalytic mesh 42, can excite electrons in the valence band. - A jump to the conduction band generates a corresponding hole h in the valence band. + This generates highly reactive oxygen species and hydroxyl radicals, which damage the internal molecular structure of DNA or RNA in the cells of microorganisms in the air, causing growth-related cell death and / or regenerative cell death. This makes the air introduced into the room fresh, clean, and safe, thus enabling the air conditioner 1000 to have a medical fresh air function, satisfying the requirements of indoor air flow and the cleanliness of the breathable air.

[0072] Specifically, such as Figure 13 As shown, the airflow discharged from the fresh air outlet can pass through the sterilization duct 20 and the sterilization and disinfection component 4 in sequence. After the airflow is sterilized by the sterilization and disinfection component 4, it is discharged through the air outlet 30 on the side wall of the pull-out component 3.

[0073] For example, in one embodiment of the present invention, the fresh air module 700 introduces outdoor fresh air through a fresh air duct. After preliminary dust removal and filtration by the fresh air HEPA filter, the fresh air passes through the UVC wavelength ultraviolet light emitted by the ultraviolet lamp 41 of the sterilization and disinfection module. Under the action of the photocatalytic mesh 42, the ultraviolet light excites electrons in the valence band. - A jump to the conduction band generates a corresponding hole h in the valence band. + It generates highly reactive oxygen species and hydroxyl radicals with strong oxidizing effects, which destroy the internal molecular structure of DNA or RNA in the cells of microorganisms in the air, causing cell death and / or regenerative cell death, thereby achieving the effect of sterilization and disinfection. The sterilization and disinfection efficiency is over 99.98%, thus realizing the secondary cleaning treatment of outdoor air and indoor polluted air.

[0074] After a period of time, the indoor air begins to become polluted. Turning on the indoor recirculation mode, the indoor air undergoes a second cleaning process through the HEPA filter, followed by ionization and neutralization by positive and negative ions at the fresh air duct. This further ionizes and destroys residual viruses and bacteria, resulting in a third cleaning treatment. Furthermore, the air passing through the heat exchanger is further purified by negative ions on both sides of the cross-flow duct outlet 30, creating a feeling of freshness reminiscent of after a rain shower.

[0075] According to an embodiment of the present invention, a sterilization device 100 for an air conditioner 100, by placing a sterilization and disinfection component 4 at the fresh air outlet, allows ultraviolet light of an appropriate wavelength emitted by an ultraviolet lamp 41 to excite electrons in the valence band under the action of a photocatalytic mesh 42. - A jump to the conduction band generates a corresponding hole h in the valence band. +, generate active oxygen with strong oxidation and hydroxyl radicals, so that the molecular internal structure of DNA or RNA in the cells of the microorganism body in the air is destroyed, causing growth cell death and / or regenerative cell death, so that the air introduced into the room reaches a fresh, clean and safe degree, so that the air conditioner 1000 can have a medical fresh air function, meeting the indoor air flow and the cleanliness of the air breathed.

[0076] In some embodiments of the present application, as shown in Figure 4 and Figure 6 , the bottom wall of the mounting seat 1 is provided with a positioning groove 11, and the bottom wall of the air duct piece 2 is provided with a positioning block 21 matched with the positioning groove 11. It can be understood that the cooperation of the positioning block 21 and the positioning groove 11 can not only reduce the difficulty of the alignment and cooperation of the mounting seat 1 and the air duct piece 2, but also improve the assembly precision and efficiency of the mounting seat 1 and the air duct piece 2. For example, in an example of the present application, the front end of the bottom wall of the air duct piece 2 is provided with two spaced apart positioning blocks 21, and the bottom wall of the mounting seat 1 is provided with two positioning grooves 11, and the two positioning grooves 11 are matched with the two positioning blocks 21 one by one.

The fastener has the advantages of simple structure and easy assembly, and the tight connection of the mounting seat 1 and the air duct piece 2 can be realized by connecting the first connecting part 12 and the second connecting part 22 through the fastener. In addition, while ensuring the connection strength of the mounting seat 1 and the air duct piece 2, the cost can also be reduced. Alternatively, the fastener can be a screw, a bolt or a stud. For example, in an example of the present application, the first connecting part 12 is a screw column, the second connecting part 22 is a connecting hole, the first connecting part 12 is two, and the second connecting part 22 is two, and the two first connecting parts 12 and the two second connecting parts 22 are connected one by one through the fastener.

It can be understood that by arranging the first protective plate 17 on the inner bottom wall of the mounting seat 1, and the first protective plate 17 is a sheet metal part, the sheet metal part can shield the ultraviolet light emitted by the ultraviolet lamp 41, thereby avoiding the ultraviolet light from irradiating on the inner bottom wall of the mounting seat 1, and further avoiding the aging of the mounting seat 1, so as to ensure the service life of the mounting seat 1.

[0079] In addition, as shown in Figure 2 、 Figure 4 and Figure 6 , by matching the first positioning column 171 with the first positioning hole 13, not only can the difficulty of aligning the mounting seat 1 and the first protective plate 17 be reduced, but also the assembly precision and efficiency of the mounting seat 1 and the first protective plate 17 can be improved.
