[0041] For example, the air conditioner 100 is a split type air conditioner 100, and the air conditioner 100 is divided into an air conditioner indoor unit and an air conditioner outdoor unit, and the air conditioner indoor unit comprises the shell assembly 2, the heat exchanger assembly 3 and the air duct assembly 4.

[0042] Referring to Figures 1-4The front of the casing assembly 2 is formed with an air outlet 22, the rear of the casing assembly 2 is formed with an air inlet 21, the heat exchanger assembly 3 is arranged in the casing assembly 2, the air duct assembly 4 is arranged in the casing assembly 2 and comprises an air duct volute 41 and a fan assembly 44, the air duct volute 41 has an air duct 414 therein which is in communication with the air inlet 21 and the air outlet 22, the fan assembly 44 is mounted on the air duct volute 41 and comprises a fan, the fan comprises a fan wheel 441 and a motor 442, the motor 442 is connected with the fan wheel 441, at least a part of the fan wheel 441 is located in the air duct 414 and the rotation axis of the fan wheel 441 extends in the up-down direction.

[0043] For example, the air conditioner 100 is a split floor type air conditioner 100, and the rotation axis of the fan wheel 441 extends in the up-down direction. During operation of the air conditioner, the fan wheel 441 rotates along the rotation axis to drive air to enter the air conditioner 100 from the rear air inlet 21 of the casing assembly 2, the air flow passes through the heat exchanger assembly 3 and exchanges heat with the heat exchanger assembly 3, and then the fan wheel 441 drives the air flow to flow along the air duct 414 and finally flows out of the air conditioner 100 through the air outlet 22.

[0044] For example, the air duct assembly 4 further comprises a motor cover 45 which can be arranged on the air duct volute 41 to shield and protect the motor 442.

[0045] For example, the motor 442 can be arranged on the upper side of the air duct volute 41, the rotation shaft of the fan wheel 441 is a fan wheel 441 rotation shaft, the upper end of the fan wheel 441 rotation shaft can be connected with the motor 442 shaft of the motor 442, the lower end of the fan wheel 441 rotation shaft can be rotationally connected with the bottom wall of the air duct volute 41, the bottom wall of the air duct volute 41 can be provided with a matching hole, and the lower end of the fan wheel 441 rotation shaft can be rotatably accommodated in the matching hole. Further, the lower end of the fan wheel 441 rotation shaft can be sleeved with a shaft sleeve 443, and the shaft sleeve 443 is accommodated in the matching hole

[0046] The air duct volute 41 comprises a front volute tongue 412, and an air inlet end 415 is formed at one end of the front volute tongue 412 close to the air inlet 21, and a flow guiding structure 416 is formed on the air inlet end 415, and the flow guiding structure 416 comprises a plurality of flow guiding teeth 417 arranged in the up-down direction. By arranging the flow guiding structure 416 on the air inlet end 415, and the flow guiding structure 416 comprises a plurality of flow guiding teeth 417, the flow guiding structure 416 close to the air inlet 21 can regulate the airflow entering the air duct 414 during the process of the airflow entering the air duct 414 from the air inlet 21 of the air duct volute 41, so that the airflow in the air duct 414 flows more orderly, the airflow direction in the air duct 414 is more uniform, and the turbulence phenomenon in the air duct 414 is reduced, thereby reducing the noise or the air duct 414 abnormal sound in the air conditioner 100, for example, reducing the surge sound. By arranging the plurality of flow guiding teeth 417 in the up-down direction, the range of the flow guiding teeth 417 in the up-down direction is wider, and the effect of reducing the noise or the air duct 414 abnormal sound in the air conditioner 100 is better.

[0047] For example, the arrangement length of the flow guiding teeth 417 in the up-down direction is the same as the extension length of the front volute tongue 412 in the up-down direction, so that the flow guiding teeth 417 can play a role in regulating the airflow in the up-down direction of the air conditioner 100, and the effect of reducing the noise or the air duct 414 abnormal sound in the air conditioner 100 is better.

[0048] For example, the shape of the flow guiding teeth 417 can be semicircular, triangular or rectangular.

[0049] For example, the plurality of flow guiding teeth 417 are arranged in the up-down direction, and the shapes of the plurality of flow guiding teeth 417 are the same. By making the shapes of the plurality of flow guiding teeth 417 the same, the flow regulating effect of the flow guiding teeth 417 on the airflow in the up-down direction is consistent, the airflow in the air duct 414 flows more orderly, the turbulence in the air duct 414 is reduced, and the effect of reducing the noise or the air duct 414 abnormal sound in the air conditioner 100 by the flow guiding teeth 417 is better.

[0050] According to the air conditioner 100 provided by the embodiment of the present application, by arranging the flow guiding structure 416 for guiding the airflow on the air inlet end 415, and the flow guiding structure 416 comprises a plurality of flow guiding teeth 417 arranged in the up-down direction, the flow guiding teeth 417 can regulate the airflow flowing through the air inlet end 415, guide the airflow flowing through the air inlet end 415 to flow in the same direction, so that the airflow flows more orderly and uniformly, the turbulence in the air duct 414 is reduced, and the noise and the air duct 414 abnormal sound are reduced.

[0051] According to some embodiments of the present application, referring to Figure 7 and Figure 8The dredging teeth 417 are in a rectangular shape. By making the dredging teeth 417 in a rectangular shape, the dredging teeth 417 can have a better air flow rectification effect.

[0052] According to some embodiments of the present application, referring to Figure 7 and Figure 8 The end of the dredging tooth 417 is formed with a circular arc chamfer 418. By making the end of the dredging tooth 417 formed with a circular arc chamfer 418, it can be avoided that the end of the dredging tooth 417 is scratched during the maintenance or repair of the air conditioner 100 by the relevant personnel.

[0053] For example, the dredging tooth 417 and the air duct volute 41 are integrally formed, the dredging tooth 417 and the air duct volute 41 are an integral injection molding part, and the end of the dredging tooth 417 is formed with a circular arc chamfer 418. By making the end of the dredging tooth 417 have a circular arc chamfer 418, the injection molding mold stress of the dredging tooth 417 can be smaller, and the dredging tooth 417 is more convenient to manufacture.

[0054] According to some embodiments of the present application, referring to Figure 8 The extension length of the dredging tooth 417 is a, a satisfies 3mm≤a≤7mm, and the extension length direction of the dredging tooth 417 is perpendicular to the up-down direction. For example, the extension length a of the dredging tooth 417 can be 3mm, 4mm, 5mm, 6mm, 7mm, etc. By making the extension length a of the dredging tooth 417 not less than 3mm, the flow guiding effect of the dredging tooth 417 can be more sufficient; by making the extension length a of the dredging tooth 417 not more than 7mm, the air inlet amount into the air duct 414 can be ensured, and the influence of the too long dredging tooth 417 on the air inlet amount into the air duct 414 can be avoided.

[0055] According to some embodiments of the present application, referring to Figure 8 The width of the dredging tooth 417 in the up-down direction is b, b satisfies 3mm≤b≤7mm. For example, the width b of the dredging tooth 417 in the up-down direction can be 3mm, 4mm, 5mm, 6mm, 7mm, etc. By making the width b of the dredging tooth 417 in the up-down direction not less than 3mm, the dredging tooth 417 can have sufficient structural strength to prevent the dredging tooth 417 from being bent; by making the width b of the dredging tooth 417 in the up-down direction not more than 7mm, a sufficient number of dredging teeth 417 can be arranged in the length direction of the air duct volute 41, so that the flow guiding effect of the dredging structure 416 is more sufficient.

[0056] According to some embodiments of the present application, referring to Figure 7 and Figure 8In the up-down direction, the adjacent guiding teeth 417 define guiding tooth grooves 419. By defining guiding tooth grooves 419 between adjacent guiding teeth 417, the air flow can pass through the guiding tooth grooves 419, and the air flow is rectified by the two guiding teeth 417 located on the upper and lower sides of the guiding tooth 417 during the process of the air flow flowing through the guiding tooth grooves 419, so that the flow direction of the air flow is more uniform.

[0057] According to some embodiments of the present application, referring to Figure 8 , the width of the guiding tooth groove 419 in the up-down direction is c, and c satisfies 3mm≤c≤6mm. For example, the width c of the guiding tooth groove 419 in the up-down direction can be 3mm, 4mm, 5mm, 6mm, etc. By making the width c of the guiding tooth groove 419 in the up-down direction not less than 3mm, the guiding tooth groove 419 can have enough gaps for the air flow to pass through; by making the width c of the guiding tooth groove 419 in the up-down direction not greater than 6mm, the air flow can be fully rectified by the guiding tooth 417 when passing through the guiding tooth groove 419, so that the guiding effect of the guiding structure 416 is more sufficient.

[0058] According to some embodiments of the present application, referring to Figure 8 , the width of the guiding tooth 417 in the up-down direction is b, the width of the guiding tooth groove 419 in the up-down direction is c, and 0.7≤c / b≤1.5. For example, the value of c / b can be 0.7, 0.9, 1.1, 1.3, 1.5, etc. By making the ratio c / b between the width c of the guiding tooth groove 419 in the up-down direction and the width b of the guiding tooth 417 in the up-down direction satisfy 0.7≤c / b≤1.5, the guiding effect of the guiding structure 416 can be more sufficient, and the air volume entering the air duct 414 can be guaranteed.

[0059] According to some embodiments of the present application, referring to Figure 2 , the air duct volute 41 includes a detachably connected front volute 411 and an air duct partition plate 413, the air duct partition plate 413 is connected with the front volute 411 and together defines two air ducts 414 arranged along the left-right direction, the air duct partition plate 413 is located between the two air ducts 414, the fan assembly 44 includes two fans arranged along the left-right direction, the fan wheels 441 of the two fans are respectively located in the two air ducts 414, the air outlets 22 are two spaced apart along the left-right direction, the two air outlets 22 are respectively communicated with the two air ducts 414, the front volute 411 includes two front volute tongues 412 located at the left and right ends, and at least one of the front volute tongues 412 has the guiding structure 416 formed thereon.

[0060] For example, the front volute 411 includes the front volute tongue 412, and the front volute tongue 412 of the front volute 411 has the guiding structure 416 formed thereon.

[0061] The fan assembly 44 includes two fans by connecting the air duct partition plate 413 with the front volute 411 and jointly defining two air ducts 414 arranged along the left-right direction, and installing the two fans in the two air ducts 414 respectively, so that the driving capacity of the air conditioner 100 on air can be improved, the air inlet and air outlet of the air conditioner 100 can be improved, and the temperature regulation efficiency can be improved. By arranging the air outlet 22 as two air outlets arranged along the left-right direction, the air outlet range of the air conditioner can be wider, and the temperature regulation efficiency can be higher. By forming the guide structure 416 on at least one front volute tongue 412, the airflow entering the at least one air duct 414 can be guided by the guide structure 416, the airflow in the at least one air duct 414 can flow more orderly, the at least one air duct 414 can reduce turbulence, and the air conditioner 100 can reduce noise or air duct 414 abnormal sound better.

[0062] For example, the front volute 411 and the air duct partition plate 413 are connected by clamping. In the related art, the front volute 411 and the air duct partition plate 413 need to be connected by fasteners 5 such as screws. By connecting the front volute 411 and the air duct partition plate 413 by clamping, the number of fasteners 5 used by the air conditioner 100 can be reduced, such as the number of screws, so that the installation and disassembly of the air conditioner 100 are more convenient.

By making the heat exchanger assembly 3 include the heat exchanger bracket 31, and making the heat exchanger 32 installed on the heat exchanger bracket 31, the heat exchanger 32 can be fixed relative to the heat exchanger bracket 31, avoiding the heat exchanger 32 from moving in the air conditioner 100, causing the heat exchanger 32 to be damaged or causing noise. By connecting the air duct volute 41 with the heat exchanger bracket 31, and connecting the heat exchanger bracket 31 with the cabinet assembly 2, the air duct volute 41 and the heat exchanger bracket 31 can be fixed relative to the cabinet assembly 2, avoiding the air duct volute 41 from moving in the air conditioner 100, causing the air duct volute 41 to be damaged or causing noise. In addition, by connecting the air duct volute 41 with the heat exchanger bracket 31, the air duct assembly 4 and the heat exchanger assembly 3 can be connected as a whole, so that the heat exchanger assembly 3 and the air duct assembly 4 can be conveniently installed and fixed in the cabinet assembly 2.

[0064] According to some embodiments of the present application, referring to Figures 9-13The front volute 411 is formed with a plurality of first mounting holes 420 arranged in the up-down direction at both left and right ends, the heat exchanger support 31 is formed with a plurality of second mounting holes 311 arranged in the up-down direction, and the casing assembly 2 is formed with a plurality of third mounting holes 23 arranged in the up-down direction. The fastener 5 is arranged in the first mounting hole 420, the second mounting hole 311 and the third mounting hole 23, so as to mount the heat exchanger assembly 3 and the air duct assembly 4 on the casing assembly 2. By arranging the fastener 5 in the first mounting hole 420, the second mounting hole 311 and the third mounting hole 23, the fastener 5 can mount the heat exchanger assembly 3 and the air duct assembly 4 on the casing assembly 2, so that the connection between the heat exchanger assembly 3, the air duct assembly 4 and the casing assembly 2 is more stable, thereby avoiding the air duct volute 41 or the heat exchanger support 31 from moving in the air conditioner 100, which can cause damage to the air duct volute 41 or the heat exchanger support 31 or cause noise.

[0065] For example, the fastener 5 can be a screw.

[0066] For example, with reference to Figure 12 The casing assembly 2 comprises a rear shell 24, and the rear shell 24 is provided with the third mounting hole 23.

[0067] For example, with reference to Figure 5 The air duct volute 41 is formed with six first mounting holes 420, wherein three first mounting holes 420 are arranged in the up-down direction on the left side of the air duct volute 41, and the first mounting holes 420 on the air duct volute 41 are arranged in left-right symmetry. Correspondingly, the heat exchanger support 31 is formed with six second mounting holes 311, and the casing assembly 2 is formed with six third mounting holes 23, and the positions of the six first mounting holes 420, the six second mounting holes 311 and the six third mounting holes 23 correspond one by one.

[0069] When the relevant personnel need to disassemble the air conditioner 100 for maintenance or repair, the relevant personnel will disassemble the fastener 5 arranged in the first mounting hole 420, the second mounting hole 311 and the third mounting hole 23, at this time, the air duct volute 41 is separated from the relative fixation with the heat exchanger support 31, but the second positioning rib plate plays a role of upward supporting on the first positioning rib plate, so that the heat exchanger support 31 plays a role of upward supporting on the air duct volute 41, and damage to nearby people or objects caused by the downward falling of the air duct volute 41 can be avoided.

[0070] When the relevant personnel need to assemble the air conditioner 100, the relevant personnel will hang the air duct volute 41 on the heat exchanger support 31, at this time, the first supporting positioning rib plate 421 and the second supporting positioning rib plate 312 are matched in the up-down direction, which can play a role of pre-positioning, prompting the relevant personnel that the air duct volute 41 is positioned correctly relative to the heat exchanger support 31, and then the relevant personnel installs the fastener 5 to fix the air duct volute 41 relative to the heat exchanger support 31.
