[0041] In the prior art, it is usually necessary to regularly disassemble the air conditioner indoor unit and use disinfectant or alcohol to disinfect the inside of the air conditioner indoor unit to sterilize the air conditioner indoor unit. However, the above-mentioned operation of disassembling the air conditioner indoor unit and disinfecting the inside of the air conditioner indoor unit is relatively complicated. Due to the complex structure of the air conditioner indoor unit, disassembling the air conditioner indoor unit usually requires professional maintenance personnel to operate, which is costly.

[0042] Based on this, the present application provides an air conditioner indoor unit, including an air duct housing, a heat exchanger and at least one sterilization module, wherein the sterilization module is installed on the air duct housing and is located on the air inlet side of the heat exchanger to sterilize the air on the air inlet side of the heat exchanger, and the sterilized air reaches the air outlet side of the heat exchanger after passing through the heat exchanger, and the air outlet side of the heat exchanger is connected with the air outlet of the air conditioner indoor unit, so that the sterilized air is sent to the room through the air inlet side and the air outlet of the heat exchanger, so that the bacteria content of the air reaching the room is low. The air conditioner indoor unit provided by the present application eliminates bacteria in the air conditioner indoor unit through the sterilization module, and there is no need to disassemble the air conditioner indoor unit. The sterilization can be started by turning on the sterilization module, and the operation is relatively simple and convenient, and no professional operation is required, which reduces the cost.

[0043] The following describes the embodiments of the present utility model in conjunction with the accompanying drawings.

[0044] Reference Figures 1 to 7 As shown, the embodiment of the present application provides an air conditioner indoor unit, which includes an air duct housing 100, a heat exchanger 300, an air inlet grille, and at least one sterilization module 200. The heat exchanger 300 is connected to the air duct housing 100. The heat exchanger 300 has an air inlet side and an air outlet side, and the air inlet side is opposite to the air inlet grille. The sterilization module 200 has at least one first connection portion 211, and the air duct housing 100 has at least one second connection portion 117, and the first connection portion 211 is connected to the second connection portion 117 in a one-to-one correspondence.

[0045] The sterilization module 200 is located on the air inlet side to sterilize the air on the air inlet side. The air conditioner indoor unit has at least one air outlet 500 , and the air outlet 500 is connected to the air outlet side of the heat exchanger 300 .

[0046] The air inlet grille has a plurality of air inlets, each of which is opposite to the heat exchanger 300. The air enters the indoor unit of the air conditioner through the air inlet and passes through the heat exchanger 300. The heat exchanger 300 exchanges heat with the air, and the air after the heat exchange is sent to the room through the air outlet 500.

[0047] The first connection portion 211 on the sterilization module 200 is connected to the second connection portion 117 on the air duct housing 100 , so that the sterilization module 200 is fixed on the air duct housing 100 .

[0048] Exemplarily, the air conditioner indoor unit further includes at least one connecting member 600, the first connecting portion 211 is a first connecting hole, the second connecting portion 117 is a second connecting hole, and each connecting member 600 is connected to each second connecting hole through the first connecting hole in a one-to-one correspondence. Exemplarily, the connecting member 600 is a screw, and the screw connection strength is relatively high, thereby making the connection between the sterilization module 200 and the air duct housing 100 more reliable.

[0049] In some embodiments, one of the first connection portion 211 and the second connection portion 117 is a buckle, and the other is a slot matching the buckle, and the buckle is engaged with the slot.

[0050] In the air conditioner indoor unit provided by the embodiment of the present application, the heat exchanger 300 is installed on the air duct housing 100, and the sterilization module 200 is located on the air inlet side of the heat exchanger 300, so as to sterilize the air on the air inlet side of the heat exchanger 300. The air inlet of the air conditioner indoor unit is located on the air inlet grille, and the air inlet side of the heat exchanger 300 is opposite to the air inlet grille, so as to sterilize the air when the air just enters the air conditioner indoor unit, so that the air flowing in the air conditioner indoor unit is all sterilized air, thereby reducing the bacterial content in the entire air conditioner indoor unit. The air outlet side of the heat exchanger 300 is connected to the air outlet 500, and the air can reach the air outlet side of the heat exchanger 300 through the heat exchanger 300 after being sterilized on the air inlet side of the heat exchanger 300, and then enter the room through the air outlet 500, so that the bacterial content of the air entering the room is less, thereby reducing the indoor bacterial content.

[0051] The air-conditioning indoor unit provided in the embodiment of the present application eliminates bacteria in the air-conditioning indoor unit through the sterilization module 200. There is no need to disassemble the air-conditioning indoor unit for sterilization. Sterilization can be started by turning on the sterilization module 200. The operation is relatively simple and convenient. No professional operation is required. The user can turn on the sterilization module 200 by himself, which reduces the cost.

[0052] Reference Figure 2 , Figure 3 and Figure 4 As shown, in a specific implementation, the air duct housing 100 has a mounting groove 111 , the second connecting portion 117 is located at one side of the mounting groove 111 , and the sterilization module 200 is at least partially located in the mounting groove 111 .

[0053] The mounting groove 111 is used to accommodate at least part of the sterilization module 200, and at least part of the bottom of the sterilization module 200 is in the groove bottom of the mounting groove 111, so that the sterilization module 200 is supported by the mounting groove 111, so that the connection between the sterilization module 200 and the air duct housing 100 is more stable, and the sterilization module 200 is not easy to be disconnected from the air duct housing 100. The second connection portion 117 is located on one side of the mounting groove 111, so as to facilitate the connection between the first connection portion 211 and the second connection portion 117.

[0054] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the air duct housing 100 includes an air duct top plate 110 and an air duct bottom plate 120 that are relatively arranged, two ends of the heat exchanger 300 are respectively connected to the air duct top plate 110 and the air duct bottom plate 120, and the mounting groove 111 is located on the air duct top plate 110.

[0055] The air duct top plate 110 is located above the air duct bottom plate 120 , and the heat exchanger 300 is located between the air duct top plate 110 and the air duct bottom plate 120 .

[0056] The mounting groove 111 is located on the air duct top plate 110, and the sterilization module 200 is partially located in the mounting groove 111, so that the sterilization module 200 is connected to the air duct top plate 110. The projection of the heat exchanger 300 on the air duct top plate 110 is located in the air duct top plate 110, and the mounting groove 111 is located on the peripheral side of the air duct top plate 110, so that the sterilization module 200 is located on the outside of the heat exchanger 300. The heat exchanger 300 is arc-shaped, and the outside of the heat exchanger 300 is the air inlet side of the heat exchanger 300, so that the sterilization module 200 can sterilize the air on the air inlet side of the heat exchanger 300.

[0057] Compared with the air duct bottom plate 120 , there are more locations on the circumference of the air duct top plate 110 where the mounting grooves 111 can be set, so it is more convenient to set the mounting grooves 111 , thereby making it more convenient to connect the sterilization module 200 to the air duct top plate 110 .

[0058] In some embodiments, the mounting groove 111 may also be disposed on the air duct bottom plate 120 .

[0059] Reference Figure 2 , Figure 3 and Figure 4 As shown, in a specific implementation, the mounting slot 111 is located at the upper middle end of the air inlet side.

[0060] Among them, the number of sterilization modules 200 is one, the number of mounting grooves 111 is one, the mounting groove 111 is located on the air duct top plate 110, the air duct top plate 110 is located above the heat exchanger 300, and the mounting groove 111 is located in the middle area of ​​the air inlet side of the heat exchanger 300, that is, the sterilization module 200 is located at the upper and middle end of the heat exchanger 300, so that the sterilization module 200 can sterilize the air on both sides of the mounting groove 111, thereby making the effective sterilization area of ​​the sterilization module 200 larger.

[0061] In some embodiments, the number of sterilization modules 200 is at least two, the number of mounting grooves 111 is the same as the number of sterilization modules 200, the mounting grooves 111 are arranged at intervals on the peripheral side of the air duct top plate 110, and the mounting grooves 111 are located directly above the air inlet side of the heat exchanger 300, so that the sterilization area of ​​the sterilization module 200 is larger, and multiple sterilization modules 200 are sterilized at the same time, and the sterilization effect is better.

[0062] Reference Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, at least one wire clamping groove 115 is provided on the air duct top plate 110, and the sterilization module 200 includes a wiring harness 230, at least part of the wiring harness 230 is located outside the mounting groove 111, and the wire clamping groove 115 is located on one side of the mounting groove 111, and the wire clamping groove 115 is used to fix the wiring harness 230.

[0063] Among them, the control circuit part of the air-conditioning indoor unit is located outside the air-conditioning indoor unit and connected to the indoor electrical socket. The end of the wiring harness 230 away from the sterilization module 200 has a wiring terminal, which is connected to the control circuit located inside the air-conditioning indoor unit.

[0064] It is understandable that when the number of the sterilization modules 200 is at least two, the sterilization modules 200 are connected in parallel. At least one wire clamping groove 115 is disposed around each installation groove 111 .

[0065] Exemplarily, the number of the mounting slot 111 is one, and the number of the wire clamping slot 115 is one.

[0066] In some embodiments, the number of mounting slots 111 is one, the number of wire clamping slots 115 is at least two, the wire clamping slots are located on the air duct top plate 110, and each wire clamping slot 115 is arranged at intervals between the mounting slot 111 and the control circuit of the air-conditioning indoor unit, so that the position of the wiring harness 230 is relatively fixed, avoiding the wiring harness 230 from moving between the mounting slot 111 and the control circuit of the air-conditioning indoor unit.

[0067] Reference Figure 6 As shown, in some embodiments, a boss 113 is provided on the air duct top plate 110, the boss 113 is located on the side of the mounting groove 111 away from the air inlet grille, and the boss 113 is connected to one side of the mounting groove 111, and a clamping plate 114 is provided on the boss 113, and a spacing is provided between the clamping plate 114 and the boss 113 to form a wire clamping groove 115.

[0068] The mounting groove 111 is located on the peripheral side of the air duct top plate 110 , and the boss 113 is located on the rear side of the mounting groove 111 .

[0069] A clamping plate 114 is disposed on the boss 113, one end of the clamping plate 114 is connected to the boss 113, the clamping plate 114 is parallel to the top surface of the boss 113, and there is a distance between the clamping plate 114 and the top surface of the boss 113, so that the clamping plate 114 and the top surface of the boss 113 form a wire clamping groove 115. The distance between the clamping plate 114 and the boss 113 can be adaptively set according to the cross-sectional area of ​​the wire harness 230 and actual needs, so that the wire harness 230 can be inserted into the wire clamping groove 115, and the wire harness 230 is not easy to escape from the wire clamping groove 115.

[0070] Exemplarily, a limit block is provided on the other end of the card plate 114 , and the limit block is located on the side of the card plate 114 facing the boss 113 to prevent the wire harness 230 from falling out of the other end of the wire harness slot 115 when the wire harness 230 is inserted into the wire harness slot 115 .

[0071] Specifically, part of the wire harness 230 is located above the mounting groove 111, and the height of the wire clamping groove 115 is increased by providing the boss 113, and the distance between the wire harness 230 and the wire clamping groove 115 is reduced, so that the wire harness 230 can be inserted into the wire clamping groove 115. The boss 113 is connected to one side of the mounting groove 111, and the boss 113 supports one side of the mounting groove 111, thereby making the mounting groove 111 more reliable.

[0072] It is understandable that the mounting groove 111 has a groove on one side corresponding to the boss 113 , and the groove has reinforcing ribs staggered in both horizontal and vertical directions, so as to reduce materials and thus reduce costs while ensuring the strength of the surrounding side of the mounting groove 111 .

[0073] Reference Figure 4 , Figure 6 and Figure 7 As shown, in a specific implementation, the boss 113 further has a connecting column 116 , and the second connecting portion 117 is located on the connecting column 116 .

[0074] The connecting column 116 is disposed on the boss 113 and the second connecting portion 117 is disposed on the connecting column 116 , so that the structure of the connecting column 116 is more stable, and thus the connection between the second connecting portion 117 and the first connecting portion 211 is more reliable.

[0075] Exemplarily, the second connection portion 117 is a second connection hole, and the axis of the second connection hole is located on the axis of the connection column 116 .

[0076] Reference Figure 7 and Figure 8As shown, in a specific implementation, the sterilization module 200 includes a mounting box 210 and at least one germicidal lamp 220 located in the mounting box 210, and the first connecting portion 211 is located on the mounting box 210. An opening 212 is provided on one side of the mounting box 210, and a groove bottom of the mounting groove 111 has an escape opening 112, and the germicidal light emitted by the germicidal lamp 220 is sequentially emitted to the air inlet side through the opening 212 and the escape opening 112.

[0077] Among them, the installation groove 111 is located on the air duct top plate 110, the avoidance opening 112 is located at the lower end of the installation groove 111, the opening 212 is located at the bottom of the installation box 210, and the germicidal lamp 220 is arranged in the installation box 210, and the germicidal lamp 220 is facing the opening 212, so that the germicidal light emitted by the germicidal lamp 220 is facing the opening 212.

[0078] Exemplarily, the installation box 210 includes a box body and a box cover, the germicidal lamp 220 is located in the box body, and the box cover is arranged on the box body to close the box body. By providing the box body and the box cover, it is convenient to install and remove the germicidal lamp 220, so as to facilitate the maintenance of the germicidal lamp 220.

[0079] Specifically, the germicidal lamp 220 includes a circuit board, which is located in the box body. The wiring harness 230 of the sterilization module 200 is the wiring harness 230 of the circuit board, and part of the wiring harness 230 extends out of the box body through the upper end of the box body.

[0080] Exemplarily, the germicidal lamp 220 is a UVC ultraviolet germicidal lamp bead. UVC ultraviolet rays have strong sterilization and air purification capabilities, can kill most bacteria and viruses, and can also eliminate odors, prevent mold and prevent corrosion.

[0081] Specifically, there are two germicidal lamps 220, which are arranged side by side in the box body. Both germicidal lamps 220 face the opening 212, and the germicidal light emitted by the two germicidal lamps 220 covers a larger area, thereby making the sterilization area of ​​the sterilization module 200 larger.

[0082] In some embodiments, the box body has at least one light-transmitting hole, which is located in the opening 212 and gradually expands from the bottom of the light-transmitting hole. The germicidal lamp 220 is located at the bottom of the light-transmitting hole.

[0083] In some embodiments, the mounting box 210 has at least two baffles, which are respectively located on both sides of the germicidal lamp 220, and the baffles are parallel to a portion of the heat exchanger 300, so as to limit the germicidal light emitted by the germicidal lamp 220 between the two baffles, and prevent the germicidal light emitted by the germicidal lamp 220 from being emitted from the air inlet, thereby ensuring the sterilization effect of the germicidal lamp 220. It is understandable that the baffle can be a reflector, and when the germicidal light emitted by the germicidal lamp 220 hits the baffle, the baffle will reflect the germicidal light, so as to reflect the germicidal light to the air inlet side of the heat exchanger 300, thereby improving the sterilization effect of the germicidal lamp 220.

[0084] In some embodiments, at least two limit blocks are provided on the installation box 210 outside the installation slot 111, and the limit blocks are respectively arranged on both sides of the installation box 210. When the installation box 210 is located in the installation slot 111, the limit blocks abut against the side walls of the installation slot 111 to support the installation box 210 and prevent the installation box 210 from falling out from the bottom of the installation slot 111.

[0085] Reference Figure 3 and Figure 5 As shown, in a specific implementation, the number of the air outlets 500 is two, and the two air outlets 500 face different directions.

[0086] Among them, by arranging two air outlets 500 facing different directions on the air conditioner indoor unit, the sterilized air can be delivered to the room through the air outlets 500 in different directions, thereby making the sterilized air cover a larger area in the room.

[0087] Specifically, the air conditioner indoor unit includes two fans 400, which are arranged in parallel, one end of the fan 400 is connected to the air duct top plate 110, and the other end of the fan 400 is connected to the air duct bottom plate 120. The heat exchanger 300 is arc-shaped, and the two fans 400 are located on the inner side of the heat exchanger 300. The two fans 400 correspond to the two air outlets 500 respectively, and the two air outlets 500 are close to the two ends of the heat exchanger 300 respectively, so that the two air outlets 500 face different directions. The two fans 400 blow the air on the air outlet side of the heat exchanger 300 to the corresponding air outlets 500, and then send the air to the room through the two air outlets 500. Exemplarily, there is an angle between the directions to which the two air outlets 500 face, so that the two air outlets 500 face different directions.

[0088] On the basis of the above-mentioned embodiment, this embodiment provides an air conditioner, including an air conditioner outdoor unit and an air conditioner indoor unit connected to the air conditioner outdoor unit.
