The invention discloses a jet flow type air conditioner indoor unit and a control method thereof. The jet flow type air conditioner indoor unit comprises an air outlet penetrating an air conditioner body, a first fan, a second fan, a first air outlet channel and a second air outlet channel. The first fan and the second fan are located in the air conditioner body and arranged on the upper side and the lower side of the air outlet correspondingly. The first air outlet channel communicates with the first fan and an upper area of the air outlet. The second air outlet channel communicates with the second fan and a lower area of the air outlet. The jet flow type air conditioner indoor unit and the control method thereof have the beneficial effects that firstly, heat exchange air sent from the interior of an air conditioner and normal-temperature air at the position of the air outlet are mixed, the air jet flow phenomenon is generated, indoor air flowing can be accelerated, the mixed air is soft, and a user can feel more comfortable when the soft mixed air is blown to the body of the user; secondly, the distance between the heat exchange air generated by the fans and the air outlet is short, the conveying speed of the heat exchange air is slightly reduced, the heat exchange air can be transmitted to the air outlet with the high speed, and the overall air outlet efficiency of the air conditioner is high; and thirdly, an air flue structure is simple, and forming is easy.
