According to some embodiments of the present invention, as shown in fig. 8, the fresh air duct member 500 includes an annular portion 520.

The annular portion 520 surrounds the ventilation opening 530, the air mixing region 120 is located on a side of the annular portion 520 facing the air outlet 110, the air-conditioning air duct communicates with the air mixing region 120 through the ventilation opening 530, the first fresh air outlet 510 is located on a side of the annular portion 520 facing the air mixing region 120, and the adjusting ring 700 is rotatably mounted in the annular portion 520, that is, the second fresh air outlet 710 may be located on a side of the first fresh air outlet 510 facing the air-conditioning fan 400.

The axial direction of the first fresh air outlet 510, the axial direction of the second fresh air outlet 710, the axial direction of the vent 530, and the axial direction of the air outlet 110 may be parallel to each other, and the central axis of the vent 530 and the central axis of the air outlet 110 may coincide with each other.

Specifically, the air-conditioned air is blown to the air mixing area 120 through the ventilation opening 530, and the fresh air is blown to the air mixing area 120 through the annular portion 520, so that the fresh air can be directly mixed with the air-conditioned air after being blown out through the second fresh air outlet 710 due to the closer distance between the first fresh air outlet 510 and the ventilation opening 530, and the air mixing effect is better. Moreover, because the adjusting ring 700 is annular, and the part of the fresh air duct member 500 is configured as the annular part 520, the matching of the adjusting ring 700 and the annular part 520 is facilitated, the adjusting ring 700 can rotate in the annular part 520 to form included angles with different angles with the annular part 520, so that the adjusting ring 700 can control the fresh air to be mixed with the air conditioning air from different directions, and the two kinds of air are mixed more uniformly.

Further, the fresh air duct extends to the inside of the annular portion 520 and surrounds the ventilation opening 530, the first fresh air outlets 510 are plural and are arranged at intervals along the circumferential direction of the annular portion 520, the second fresh air outlets 710 are plural and are arranged at intervals along the circumferential direction of the adjusting ring 700, and the adjusting ring 700 controls the air volume entering the air mixing region 120 from the fresh air duct member 500 by adjusting the overlapping ratio of the plural second fresh air outlets 710 and the plural first fresh air outlets 510.

Through a plurality of first fresh air export 510 and a plurality of second fresh air export 710 cooperatees, and a plurality of first fresh air export 510 and a plurality of second fresh air export 710 all set up around the circumference interval of vent 530, can control the new trend like this and evenly blow off by the circumference of annular part 520, on the one hand, the air-out area of new trend is bigger, the difficult condition that blocks up first fresh air export 510 that interferes each other between the new trend appears, be favorable to improving the air-out efficiency of new trend, on the other hand, the new trend mixes with the air conditioner wind from the circumference of air conditioner wind, it is more even to mix.

In some embodiments of the present invention, the plurality of first fresh air outlets 510 are arranged along the circumference of the annular portion 520 for a full circumference, and the plurality of second fresh air outlets 710 are arranged along the circumference of the adjustment ring 700 for a half circumference.

Specifically, the first fresh air outlets 510 disposed in the circumferential direction of the annular portion 520 may be communicated with the air mixing region 120, and since only half of the area of the adjusting ring 700 is provided with the second fresh air outlets 710, when the second fresh air outlets 710 correspond to a portion of the first fresh air outlets 510, another portion of the first fresh air outlets 510 is blocked by the adjusting ring 700, so that only half of the first fresh air outlets 510 may discharge air.

In this way, by changing the relative positions of the adjusting ring 700 and the annular portion 520, the air can be discharged from the upper or lower peripheral portion of the annular portion 520 separately, or from the left or right peripheral portion of the annular portion 520 separately.

For example, when the air conditioner indoor unit 1 heats, the air conditioner indoor unit 1 blows hot air, and at this time, the adjusting ring 700 is rotated to blow out fresh air from the upper half circumference of the annular part 520, so that the fresh air can not only reduce the temperature of the air conditioner air, but also enable the air outlet 110 to blow out air towards the front lower part, so that the air from the air outlet can heat the air in the indoor lower space first, and because the hot air has a rising trend, the air from the air outlet can rise again to heat the air in the indoor upper space, so that the indoor overall temperature is uniformly raised;

when the air conditioner indoor unit 1 is refrigerating, the air conditioner indoor unit 1 blows out cold air, the adjusting ring 700 is adjusted by rotating at the moment, the air is discharged from the lower half of the annular part 520, therefore, the fresh air can not only raise the temperature of the air conditioner air, but also enable the air outlet 110 to discharge the air towards the front upper part, the air discharged from the air outlet can cool the air in the upper indoor space firstly, and the cold air has a descending trend, so that the discharged air at the air outlet can be lowered again to cool the air in the lower indoor space, and the indoor overall temperature is uniformly lowered more.

The first upper fresh air outlets 511 are arranged on the upper half of the annular portion 520, and the first lower fresh air outlets 512 are arranged on the lower half of the annular portion 520. The second fresh air outlets 710 include a second fresh air outlet 711 and a second fresh air outlet 712, the second fresh air outlet 711 is arranged on one half of the adjusting ring 700, and the second fresh air outlet 712 is arranged on the other half of the adjusting ring 700.

When the second upper fresh air outlets 711 and the first upper fresh air outlets 511 are completely overlapped in a one-to-one correspondence manner, the second lower fresh air outlets 712 and the first lower fresh air outlets 512 are completely staggered; when the second lower fresh air outlets 712 completely overlap the first lower fresh air outlets 512 in a one-to-one correspondence, the second upper fresh air outlets 711 are completely staggered from the first upper fresh air outlets 511.

For example, the first upper fresh air outlets 511 and the second lower fresh air outlets 712 are uniformly arranged along the circumferential direction of the annular portion 520, the second upper fresh air outlets 711 are uniformly distributed along one half of the adjusting ring 700, and the second lower fresh air outlets 712 are uniformly distributed along the other half of the adjusting ring 700. The central angle corresponding to the adjacent first fresh air outlet 510, the central angle corresponding to the adjacent second upper fresh air outlet 711 and the central angle corresponding to the adjacent second lower fresh air outlet 712 are the same, and the central angles corresponding to the adjacent second upper fresh air outlet 711 and the adjacent second lower fresh air outlet 712 are different from the central angles.

Thus, when the second upper fresh air outlets 711 and the first upper fresh air outlets 511 are completely overlapped in a one-to-one correspondence manner, the second lower fresh air outlets 712 can be staggered with the first lower fresh air outlets 512, and air outlet from the first upper fresh air outlets 511 is realized. Or, when the second lower fresh air outlets 712 completely overlap with the first lower fresh air outlets 512 in a one-to-one correspondence manner, the second upper fresh air outlets 711 can be staggered with the first upper fresh air outlets 511, that is, only the first lower fresh air outlets 512 are used for air outlet. When the second upper fresh air outlets 711 and the first upper fresh air outlets 511 are staggered, the second lower fresh air outlets 712 and the first lower fresh air outlets 512 can also be staggered.

In summary, the adjustment ring 700 is rotated by a small amplitude, so that the first upper fresh air outlet 511 and the first lower fresh air outlet 512 can be opened and closed, and the air output of the first fresh air outlet 510 can be adjusted more conveniently and quickly.

An air conditioner including the air conditioner outdoor unit of the present application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
