In winter, in order to ensure the air conditioning effect, doors and windows are closed for a long time, and the repeated circulation of indoor air will increase the probability of cross infection among people.

[0003] Many manufacturers at home and abroad have proposed the concept of integrating sterilization functions into air conditioners. The main sterilization methods include UVC deep ultraviolet rays, nano water ions, plasma, ozone, electrical dust collection, self-cleaning + high temperature, etc. These sterilization methods have their own advantages and disadvantages, but they all have more or less the sterilization rate needs to be improved, the user perception of the sterilization process is weak, and the visualization of the sterilization process is low.

[0004] At present, there is a new type of sterilization technology, pulse sterilization technology, which releases energy in the form of full-spectrum white light through the self-ionization and avalanche discharge of inert gas in a very short time. The instantaneous light power can reach 10 million times the power of ordinary sunlight, which can instantly kill all kinds of microorganisms without causing obvious temperature changes to the sterilized objects. It has been applied in water disinfection, food sanitation and medical hygiene, but it has not been promoted in the field of air conditioning until it is miniaturized.

[0005] Pulse sterilization usually uses xenon lamps, and the installation structure is heavier and larger than traditional UVC modules, so the installation space requirements are larger and must have a certain load-bearing capacity; in addition, pulse sterilization requires the supply of high-voltage pulse electricity, and the electric module requires a larger capacitor, so the installation location of the electric module also needs to be considered comprehensively in terms of load-bearing capacity, space, and wiring.

[0037] When the air conditioner is running in cooling mode, the indoor evaporator will produce condensed water, which provides favorable conditions for the growth of bacteria and other microorganisms, which can easily cause discomfort to the human body and even "air conditioning disease". For this reason, air conditioners with sterilization functions have emerged, but their current structures are complex and unreasonable, resulting in poor overall performance of the air conditioner. To this end, the applicant proposes the following technical solutions:

[0038] like Figure 1-7 As shown, an air-conditioning indoor unit includes a middle frame 9, a panel 6 is arranged on the outer side of the middle frame 9, an evaporator 1 is arranged on the inner side of the middle frame 9, a pulse sterilization component 2 is fixedly installed on the middle frame 9, the pulse sterilization component 2 is located between the middle frame 9 and the panel 6, and the pulse sterilization component 2 includes a pulse light source module 21 and a pulse electric control module 22 that are electrically connected to each other, and the pulse light source module 21 and the pulse electric control module 22 are arranged along the length direction of the middle frame 9.

After opening the panel 6, the pulse sterilization component 2 can be inspected and repaired, and the evaporator 1 and the air inlet grille located on the upper part of the indoor unit can be sterilized at the same time. The entire pulse sterilization component 2 is located on the upper front side of the evaporator 1 and will not interfere with the air flow in the evaporator 1. The structure is reasonable and the user experience is good.

[0040] The air conditioner also includes an electric control box 3, a right end cover 4, a left end cover 5, an air guide assembly 7, a base 8 and a wall-mounted plate 10.

[0042] This arrangement allows the pulse sterilization component 2 to be directly mounted on the upper portion of the middle frame 9, minimizing the obstruction of the pulse sterilization component 2 to the airflow when the sterilization function is not turned on; at the same time, the pulse wave or light generated by the pulse sterilization component 2 can radiate the evaporator 9 as much as possible, with a wide coverage range.

[0043] Preferably, a wire clip is provided on the middle frame 9, and the wire clip is located between the pulse light source module 21 and the pulse electric control module 22, and is used to limit the connection between the pulse electric control module 22 and the electric control box 3. This setting can make full use of the existing structure of the middle frame 9 and is convenient for production and processing.

[0044] As an example of the present invention, the middle frame 9 includes a first vertical support column 91, a second vertical support column 92 and a third vertical support column 93 arranged in sequence in the length direction, and the two ends of the pulse light source module 21 are respectively mounted on the first vertical support column 91 and the second vertical support column 92, and a bracket 94 is integrally formed between the second vertical support column 92 and the third vertical support column 93, and the pulse electric control module 22 is mounted on the bracket 94. This setting installs the pulse light source module 21 and the pulse electric control module 22 to different positions of the middle frame 9, which is conducive to dispersing the load; fully utilizes the internal space of the air conditioner, and makes little change to the existing structure.

[0045] As an example of the present invention, a first connecting plate 911 is arranged on a side of the first vertical support column 91 close to the second vertical support column 92, the first vertical connecting plate 911 extends along the length direction of the second vertical support column 92 and is provided with a slot, a second connecting plate 921 is arranged on a side of the second vertical support column 92 close to the first vertical support column 91, the second connecting plate 921 is perpendicular to the first connecting plate 911 and extends along the length direction of the middle frame 9, an assembly hole is provided on the second connecting plate 921, and the first connecting plate 911 and the second connecting plate 921 are jointly used for the limited assembly of the pulse sterilization module 21.

[0046] This arrangement enables the pulse sterilization module 21 to be located as a whole on the side of the middle frame 9 close to the evaporator 1, which has a good sterilization effect on the evaporator 1 and the internal air duct; it basically does not increase the size of the air conditioner indoor unit, and the existing air conditioner is modified little, which is easy to implement. Preferably, the first connecting plate 911 and the first vertical support column 91 are integrally formed. This arrangement can ensure that the assembly of the pulse sterilization module 21 is stable and reliable.

[0047] As an example of the present invention, the bracket 94 is provided with a cavity portion 941, and a hollow portion 942 is provided on the bottom surface of the cavity portion 941. Preferably, the cavity portion 941 is formed by a portion of the bracket 94 being recessed downward. This arrangement enables it to be integrally formed, and the mechanical strength meets the assembly requirements; at the same time, the hollow portion 942 is provided to facilitate heat dissipation of the pulse electric control module 22 after assembly. The hollow portion 942 can be composed of a round hole, a square hole or a hollow pattern, and is characterized in that it is connected to the inside of the middle frame 2, which is conducive to heat exchange and cooling using the cold generated by the evaporator 1.

[0048] Preferably, a second slot 943 is disposed on one side of the cavity portion 941 , and a fixing column 944 is disposed on the other side of the cavity portion 941 . The second slot 943 cooperates with the fixing column 944 to quickly assemble the pulse electric control module 22 .

[0049] like Figure 8 As shown, the pulse light source module 21 includes a fixing seat 211 disposed on the middle frame 9, a bracket 212 is disposed on the side of the fixing seat 211 away from the panel 6, a pulse germicidal lamp 213 is disposed between the fixing seat 211 and the bracket 212, sealing plugs 214 are disposed at both ends of the pulse germicidal lamp 213, and the pulse germicidal lamp 213 is electrically connected to the pulse electric control module 22. This arrangement can make full use of the internal space of the indoor unit of the air conditioner, with little modification to the existing structure; at the same time, it ensures that the light or pulse emitted by the pulse germicidal lamp 213 is directed toward the air inlet side, that is, above the air conditioner, and will not cause harm to the user.

[0050] like Fig. 9 As shown, the fixing seat 211 includes a bottom plate 2111 , and a first side plate 2112 and a second side plate 2113 are arranged on one side of the bottom plate 2111 . There is a gap between the first side plate 2112 and the second side plate 2113 for limiting the assembly bracket 212 .

[0051] Preferably, a connecting plate 2114 is provided at one end of the bottom plate 2111 for screwing and fixing with the first connecting plate 911; a first plug 2115 is provided at one end of the bottom plate 2111 away from the connecting plate 2114 for plugging and fixing with the second connecting plate 921. This arrangement has a simple structure, and the pulse light source module 21 can be quickly disassembled and assembled after the panel 6 is opened, which is convenient for maintenance.

[0052] As an example of the present invention, a baffle 2117 is disposed at at least one end of the bottom plate 2111, and the baffle 2117 is disposed perpendicular to the bottom plate 2111. This arrangement can shield the pulse germicidal lamp 213 from both sides to prevent foreign matter from contacting the pulse germicidal lamp 213 and causing damage.

[0054] Preferably, the longitudinal height of the second notch 2124 is H 1 , the height of the bracket 212 is H 2 , of which 0.4*H 2 <H 1 <0.8*H 1 This arrangement prevents the fixing base 211 from blocking the light generated by the pulse sterilization lamp 213, thereby achieving a good sterilization effect and facilitating heat dissipation. As an example of the present invention, the length of the second notch 2124 is L 1 , the length of the bracket 212 is L2 , of which 0.6*L 2 <L 1 <0.9*L 2 This arrangement can improve the sterilization performance and heat dissipation performance of the pulse light source module 21, while making it have good mechanical strength and a long service life.

The pulse frequency of the pulse sterilization lamp 213 can be adjusted according to the number of bacteria, for example, first fast and then slow every other time in the sterilization cycle.

[0057] During assembly, first install the sealing plugs 214 at both ends of the pulse sterilization lamp 213, install the pulse sterilization lamp 213 into the limit groove 2121 of the bracket 212, and then snap-fit ​​the bracket 212 to the fixing seat 211 to form a pulse light source module 21, and then assemble the pulse light source module 21 to the middle frame 9 through the connecting plate 2114 and the first plug 2115; the power cord of the pulse sterilization lamp 213 is connected to the pulse electric control module 22, and the connecting line of the pulse electric control module 22 is routed along the wire buckle on the middle frame 9 to the electric control box 3.
