It should be noted that, for a wall-mounted air conditioner, the length of the length extension direction of the air outlet 11 here can be understood as a horizontal direction, and the corresponding width direction of the air outlet 11 can be understood as a vertical height direction. For a cabinet air conditioner, it is just the opposite.
