Fig. 1 is a schematic structural view of an air duct machine according to an embodiment of the present utility model, and as shown in fig. 1, an embodiment of the present utility model provides an air duct machine 1, including a housing 10 for forming an outer surface, in which a heat exchanging air duct is provided, and a motor 30, and a centrifugal fan assembly having at least one centrifugal fan 20, which is provided in the heat exchanging air duct. Part or all of the motor 30 is disposed outside the housing 10, and the motor 30 is used to drive the centrifugal fan assembly to operate so that the air flows in the heat exchange air duct.

When the motor 30 is fully or partially arranged outside the casing 10, the motor 30 does not occupy the space of the heat exchange air duct, compared with the situation that the motor 30 is fully arranged in the heat exchange air duct, namely, the casing 10, the distance between the centrifugal fan assembly and the left side wall and the right side wall of the casing 10 is increased, and when the centrifugal fan assembly works, the air inlet space of the air inlet side is larger, so that the air inlet quantity is larger, and the air outlet quantity is also larger. The arrangement can prevent the motor 30 from occupying the air inlet space of the centrifugal fan 20, prevent the motor 30 from blocking the air inlet of the centrifugal fan 20, and increase the air inlet quantity of the centrifugal fan 20. The motor 30 is a single-shaft motor 30.

Referring to fig. 2, in some embodiments of the present utility model, there are at least two centrifugal fans 20, and at least two centrifugal fans 20 are coaxially disposed. Preferably, the centrifugal fan 20 is provided with two. The rotating shafts of the centrifugal fans 20 are fixedly connected or integrally formed or in transmission connection through a first transmission device, and the output shaft of the motor 30 is fixedly connected or integrally formed or in transmission connection through a second transmission device with the rotating shaft of the centrifugal fan 20 close to the motor. Specifically, when the ducted air conditioner 1 starts to operate, the output shaft of the motor 30 rotates to drive all the centrifugal fans 20 to start to operate, and air flow is sucked into the centrifugal fans 20.

Referring to fig. 3, in some embodiments of the utility model, the two distances between the centrifugal fan assembly and the two sidewalls of the housing 10 perpendicular to the axis of the centrifugal fan 20 are a first distance and a second distance, respectively, the first distance being less than or equal to the second distance. The ratio between the first distance and the distance between every two adjacent centrifugal fans 20 is 1/4 to 1.

In the ducted air machine 1 before the present utility model, the ratio between the first distance and the second distance and the distance between every two adjacent centrifugal fans 20 is less than 1/4. When the motor 30 is partially or entirely disposed outside the casing 10, the distance between the two centrifugal fans 20 can be reduced, i.e., the two centrifugal fans 20 can be brought close to each other, when the motor 30 is disposed between the adjacent centrifugal fans 20 in the casing 10, both the first distance and the second distance are increased, and the distance between the two adjacent centrifugal fans 20 is reduced, which makes the ratio between the first distance and the distance between every two adjacent centrifugal fans 20 large and is in the range of 1/4 to 1, so that the arrangement can improve the suction efficiency of the centrifugal fans 20.

In some preferred embodiments of the present utility model, the ratio between the first distance and the distance between each two adjacent centrifugal fans 20 is 4/5 to 1/2, and the first distance is equal to the second distance.

Referring to fig. 1, in some embodiments of the present utility model, the ducted air machine 1 further includes a first mounting lug 13, and a sidewall of the housing 10 to which the motor 30 is mounted is a first sidewall 11. The first mounting lug 13 is provided on the first side wall 11, and a portion where the first mounting lug 13 is connected with an external structure is a connection portion, which is located on the upper side of the motor 30. The distance between the surface of the motor 30 facing away from the housing 10 and the end face of the first mounting lug 13 at the end facing away from the housing 10 is 0mm to 50mm. That is, the edge of the motor 30 does not exceed or slightly exceeds the edge in the length direction of the first mounting shackle 13, preferably does not exceed. Because the first mounting lifting lug 13 belongs to the existing structure of the air duct machine 1, and the length dimension of the first mounting lifting lug 13 is fixed, the length dimension of the whole air duct machine 1 cannot be increased when the motor 30 is arranged outside the shell 10, and the existing structure is fully utilized by the arrangement, so that the whole length dimension of the air duct machine 1 is prevented from being increased.

Referring to fig. 1 and 3, in some embodiments of the present utility model, a mounting box 31 is further included, and the mounting box 31 is mounted to the housing 10 and is used to receive and fix the motor 30. Further, when the motor 30 is disposed entirely outside the housing 10, the mounting box 31 is disposed on the outer surface of the first side wall 11. When the motor 30 is partially disposed at the outer side, a mounting box 31 is partially disposed on the outer surface of the first sidewall 11, and another portion of the mounting box 31 is embedded in the housing 10 to receive and fix the portion of the motor 30 disposed in the housing 10. The motor 30 is protected from being damaged by external objects, and meanwhile, the motor 30 is prevented from moving during operation, so that the normal operation of the air duct machine 1 is prevented from being influenced.

Referring to fig. 4, in some embodiments of the present utility model, the ducted air conditioner 1 further includes a fixing column 15, a side wall of the heat exchange duct opposite to the side wall on which the motor 30 is mounted is a second side wall 12, the fixing column 15 is disposed on the second side wall 12 and extends into the housing 10, and the fixing column 15 is disposed coaxially with the centrifugal fan 20. The end face of the fixing column 15 facing the centrifugal fan 20 is provided with a fixing needle 16 extending along the axis of the fixing column 15, and the fixing needle 16 is inserted into the rotating shaft of the centrifugal fan 20 near the second side wall 12 to realize rotational connection with the centrifugal fan 20 near the second side wall 12. This arrangement strengthens the connection of the centrifugal fan 20 to the housing 10, so that the ducted air machine 1 works more stably.

Referring to fig. 1, in some embodiments of the present utility model, the ducted air conditioner 1 further includes a plurality of second mounting lugs 14 provided on the housing 10, the second mounting lugs 14 being provided at the same level as the first mounting lugs 13. The second mounting shackle 14 is identical in structure to the first mounting shackle 13. Preferably, the second mounting lugs 14 are provided in three, one of which is provided on the first side wall 11 and is spaced apart from the first mounting lugs 13 in parallel. Wherein the other two second mounting lugs 14 are provided on the second side wall 12, and the two second mounting lugs 14 mounted on the second side wall 12 are arranged in parallel at a spacing and are provided corresponding to the first mounting lugs 13 and the second mounting lugs 14 mounted on the first side wall 11 in the length direction of the housing 10.
