In order to ensure the air supply effect, a side surface of the base 10 facing the inside of the housing is provided with a flow guide structure 12 for guiding the air flow in a direction close to the air inlet casing 20, and the flow guide structure 12 is located at the circumferential edge of the base 10.
That is, the air outlet angle of the air outlet of the air duct formed by the flow guiding structure 12 of the indoor unit faces the air inlet direction. And the value range of the air outlet angle delta is 45-50 degrees, so that good refrigerating and heating comfort is ensured.

When the indoor unit works, under the refrigeration working condition, the upper side, the left side and the right side of the indoor unit are respectively provided with an air outlet 31. That is, when the indoor unit is in the cooling condition, the air outlet 31 in the middle faces upward and discharges air, the air outlet 31 on the left side faces leftward and discharges air, and the air outlet 31 on the right side faces rightward and discharges air. Since the density of the cool air is high, the cool air at the upper outlet 31 falls down after being blown out, thereby achieving the shower effect.
Under the heating working condition, the air guide shell 30 rotates 180 degrees along with the air inlet shell 20 under the control of the motor, so that the lower side, the left side and the right side are respectively provided with an air outlet 31. That is, the central outlet 31 is directed downward to discharge air, the left outlet 31 is directed leftward to discharge air, and the right outlet 31 is directed rightward to discharge air. Since the hot air density is low, the hot air blown out from the lower side rises. Therefore, the air outlet directions under different working conditions are different, and the comfort level of the user is improved.
According to another aspect of the present invention, an air conditioner is provided, which includes an indoor unit and an outdoor unit, wherein the indoor unit is the indoor unit described above.
A second heat exchanger communicated with the first heat exchanger 40 of the indoor unit is arranged in the outdoor unit.

Therefore, the air is not blocked by the wall in the path of entering the air conditioner, and the loss along the path is small, so that the air volume of the air conditioner and the surface air speed of the first heat exchanger 40 are effectively ensured, and the heat exchange efficiency is ensured.
The distance L between the air inlet and the air outlet in the direction perpendicular to the wall is larger than 50mm, and the purpose of preventing air which is just blown out from the air outlet from being sucked back can be achieved.
The indoor unit and the air conditioner with the indoor unit have the following technical effects:
the front air inlet structure enables the space around the air inlet to be larger, the distance of air entering the air channel is not blocked by a wall, and energy loss is smaller, so that the air quantity of the air conditioner and the air speed flowing through the first heat exchanger are guaranteed. The surface wind speed of the first heat exchanger is good, and high-efficiency heat exchange efficiency is facilitated. Moreover, the effective windward area of the first heat exchanger is greatly increased, and the heat exchange efficiency is higher.
The direction of three air outlet can be adjusted according to different work condition for the comfort level that the user used promotes.
