The fan 5 in this embodiment is a mixed-flow fan. The mixed-flow fan has a small volume and circular characteristic. The fan reversing basically does not increase the space volume of the indoor unit of the air conditioner. The high-speed fan can greatly reduce the volume of the fan and further reduce the unit. Overall volume; the air outlet of the mixed flow fan is circular. Compared with the traditional centrifugal fan, the air outlet basically covers the upper and lower surfaces of the heat exchanger. The circular air outlet is more uniform, which greatly reduces the uneven distribution of air volume on the surface of the heat exchanger, thereby reducing The uneven distribution of the surface temperature of the heat exchanger makes the user's wind experience better.

Due to the use of mixed flow fans, the surface wind speed of the heat exchanger is more uniform. Under the same air volume and the same windward area, the surface wind speed of the heat exchanger will not appear at a higher wind speed area. The fluid further reduces the resistance of the unit's return air; more importantly, this technical solution has only one fan system, unlike the previous solution, another fan becomes a source of resistance or a new source of noise for the unit; therefore, the noise of the unit can be significantly reduced .

The "V" type heat exchanger is arranged at the tuyere of the mixed flow fan, so that the air volume distribution on the surface of the heat exchanger is more uniform, the heat exchange effect is better, and the volume of the heat exchanger can be greatly reduced; materials are saved and the cost of the unit is reduced; at the same time, due to heat exchange The wind speed on the surface of the unit is uniform, and the temperature distribution at the air outlet of the unit is more even. The minimum temperature of the air outlet at the air outlet has been greatly improved compared with previous fan solutions, which reduces the risk of condensation of the unit.

Mixed-flow fans (different from the prior art schemes using centrifugal fans, cross-flow fans, and axial fans) are small in volume and large in air volume. Small volume fans can achieve large air volume output. Because the mixed-flow fan is similar to a "sphere" in structure, it does not look like a centrifugal. The fan needs a large volute, and the cross flow fan needs a vortex tongue structure. The rotation of these fan systems requires a larger unit space; this technical solution does not need to increase the unit space volume too much (basically not increase); therefore, compared to the past The solution can greatly reduce the size of the unit.

According to another aspect of the present disclosure, this embodiment also provides an air conditioner, which includes the above-mentioned air conditioner indoor unit. In some embodiments, the indoor unit of the air conditioner is a duct machine.

Example two

Fig. 12 shows a schematic structural diagram of the indoor unit of the air conditioner of this embodiment. The difference between this embodiment and the first embodiment is that the first heat exchanger 41 and the second heat exchanger 42 of the heat exchanger 4 are arranged in a V-shape. A flow guiding member 13 is provided on the bisector of the angle of the first heat exchanger 41 and the second heat exchanger 42. The air guiding member 13 extends along the direction of the bisector of the angle of the first heat exchanger 41 and the second heat exchanger 42.

By arranging the guide member 13 between the first heat exchanger 41 and the second heat exchanger 42, the airflow from the first heat exchanger 41 and the airflow from the second heat exchanger 42 can be separated, avoiding the airflow from the second heat exchanger. The air flow from the first heat exchanger 41 and the air flow from the second heat exchanger 42 intersect to generate a vortex. The reduction of the vortex can reduce the impact on the air output, reduce noise, and improve user experience.

In some embodiments, the flow channel inside the indoor unit is also provided with a guide member.
