Fig. 1 is a schematic front view of an indoor unit of an air conditioner according to an embodiment of the present utility model, and referring to fig. 2 to 5, the indoor unit of an air conditioner according to an embodiment of the present utility model includes two air outlet portions 10, and the two air outlet portions 10 are spaced apart so that an induced air space 20 is formed between the two air outlet portions 10. The front end of the side wall of each induced air interval 20 is provided with a groove 13, the grooves 13 on the side walls of the two induced air intervals 20 are oppositely arranged, and the axes of the grooves 13 on the side walls of each induced air interval 20 are vertically arranged.

In these embodiments, when at least one of the air outlet portions 10 blows the heat exchange air flow forward, the air in the air introducing space 20 is driven forward by the negative pressure. The air in the induced air interval flows forward and passes through the grooves 13, so that the flowing direction of the air flow passing through the two side walls is far away from the air outlet part 10 corresponding to the side walls. As shown in fig. 5, a is an area where the air flow blown out from the first air outlet and the air flow blown out from the induced air interval are not mixed. The grooves are arranged so that the air with room temperature in the induced air interval is mixed with the heat exchange air flow at a distance in front of the air outlet portion 10. As shown in fig. 4, the air with room temperature in the induced air space is mixed with the heat exchange air flow near the surface of the air outlet portion 10 to generate condensation on the surface because the induced air channel is not provided with the groove 13.

Of course, in some embodiments of the present utility model, the plurality of grooves 13 may be multiple, the plurality of grooves 13 are disposed on the side wall of the induced air channel, and the axes of the plurality of grooves 13 are coincident or not coincident, so that the plurality of grooves 13 can also function to avoid condensation.

In some embodiments of the utility model, as shown in fig. 2, the groove 13 is an arcuate groove. The axis of the arcuate slot extends along the length of the induced draft gap 20. The arrangement of the arc-shaped groove is more beneficial to the flow of the air flow.

In some embodiments of the utility model, the front edges of the two grooves 13 are the two vertical edges of the induced draft interval 20. This arrangement causes the air flow from the induced air compartment to change direction at the outlet of the induced air compartment 20 such that the air having room temperature in the induced air compartment is mixed with the heat exchange air flow as far as possible in front of the air outlet portion 10, thereby avoiding the generation of condensation as much as possible.

In some embodiments of the present utility model, the front end of the induced draft interval 20 is connected to the air outlets on both sides through an arc surface. The arc surface extends along the length direction of the air outlet part 10, and protrudes towards the front of the air induction interval 20. The arrangement of the arc-shaped surface is beneficial to mixing the air flow at the induced air interval with the air flow of the air outlet part.

In some embodiments of the utility model, the width between the rear ends of the two arcuate slots is less than the width between the front ends of the two arcuate slots. This arrangement facilitates the flow of air entering from the rear end of the arcuate slot out of the front end of the arcuate slot after acceleration.

In some embodiments of the present utility model, as shown in fig. 2, the air intake section includes an arc segment portion and a straight segment portion connected to each other, the arc segment portion being on a rear side of the straight segment portion.

In some embodiments of the present utility model, as shown in fig. 2, an air outlet structure 18 is disposed at the second air outlet 17, and the air outlet structure 18 causes the air outlet passing through the second air outlet 17 to blow out toward the front side of the second air outlet 17 near the third edge. That is, the wind entering the bypass duct can change the wind direction after passing through the wind outlet structure 18, and enlarge the wind outlet angle.

In some embodiments of the present utility model, as shown in fig. 3, the air outlet structure 18 includes a plurality of arc plates, and the plurality of arc plates are disposed in parallel, and the plurality of arc plates protrude toward the front of the first air outlet 11, so that the air outlet passing through the arc plates blows out toward the front side of the second air outlet 17 near the third edge.
