In this embodiment, the air outlet channel 306 is divided into a plurality of sub air outlet channels 3061 by the partition 307, and since the plurality of sub air outlet channels 3061 are all communicated with the inlet and the outlet 303, each sub air outlet channel 3061 can guide the air flow flowing in from the inlet to the outlet 303. The air outlet amount of each part of the outlet 303 of the air supply barrel 30 can be adjusted by the plurality of sub air outlet channels 3061.

Optionally, the housing 305 includes a first end portion 3081, a second end portion 3082 and an annular sidewall 308, the annular sidewall 308 is connected between the first end portion 3081 and the second end portion 3082, and the outlet 303 is disposed on the annular sidewall 308 and extends along the length of the blower barrel 30; the partition 307 is provided on the inner wall surface of the outlet duct 306 (i.e., the inner wall surface of the blower casing 30) and located at the outlet 303.

In this embodiment, the annular sidewall 308 of the air supply duct 30 is longer, and the outlet 303 is disposed on the annular sidewall 308, so that the air outlet area of the air supply duct 30 is increased, and the air outlet volume of the air conditioner is increased. The partition 307 is located at the outlet 303, and can more accurately guide the airflow at the inlet to the outlet 303, so that the outlet air of the outlet 303 is convenient to adjust.

In this embodiment, the inlet is disposed at the first end portion 3081 and/or the second end portion 3082, the outlet 303 is disposed at the annular sidewall 308, and the airflow needs to flow along the length direction of the blower barrel 30 first and then flow along the radial direction of the blower barrel 30. The first connecting segment 3071 is used for guiding the gas flow at the inlet to the second connecting segment 3072, and the second connecting segment 3072 is used for guiding the gas flow at the first connecting segment 3071 to the outlet 303.

For example, the distance between the first connecting segment 3071 of the plurality of partition plates 307 and the outlet 303 gradually increases along the flowing direction of the air flow in the air outlet duct 306.

In this embodiment, the distance between the first connecting segment 3071 of the plurality of partition plates 307 and the outlet 303 gradually increases, which can be understood as follows: the second coupling segment 3072 gradually increases in length in the radial direction of the barrel 30. With such an arrangement, along the flowing direction of the air flow in the air outlet duct 306, the distance between the first connecting section 3071 and the inner wall surface of the air outlet duct 306 away from the outlet 303 is gradually reduced, which can be understood as follows: along the flow direction of the air flow in the air outlet duct 306, the flow area of each sub air outlet duct 3061 and the inlet along the radial direction of the air supply barrel 30 gradually increases.

The shorter the distance from the inlet in the outlet air duct 306, the faster the wind speed, so the smaller the communication area of the sub outlet air duct 3061 near the inlet in the radial direction with the inlet, and the sufficient wind can be guided out. Meanwhile, the distance between the first connecting section 3071 near the inlet and the air outlet channel 306 far away from the outlet 303 is larger, so that more air flows into the sub air outlet channel 3061 far away from the inlet. Through the setting of the partition 307 of the embodiment, the air outlet of each sub air outlet channel 3061 is more uniform, and the uniform air outlet of the air conditioner can be realized.
