Therefore, through the auxiliary air guide plate 9, when the air conditioner 100 works, the air blown out from the air outlet 31 can be better guided through the combined action of the auxiliary air guide plate 9 and the main air guide plate 8, so that the comfort of the air conditioner 100 can be further improved, and the higher use requirement is met.
For example, referring to fig. 2, when the air conditioner 100 is in the cooling mode, the auxiliary air guide plate 9 is located at the storage position, the auxiliary air guide plate 9 is located at one side of the air outlet 31 (for example, the front side of the air outlet 31) and extends obliquely upward in a direction from the air outlet 31 to the side wall of the casing 1 (for example, the front side wall of the casing 1), the position of the bottom wall of the casing 1 opposite to the auxiliary air guide plate 9 coincides with the oblique direction of the auxiliary air guide plate 9, and the bottom surface of the auxiliary air guide plate 9 forms the above-mentioned guide inclined surface 91, whereby the air blown out from the air outlet 31 can flow obliquely upward through the guide action of the guide inclined surface 91, improving the comfort of the air conditioner 100 in the cooling mode.
For example, referring to fig. 3, when the air conditioner 100 is in the heating mode, the auxiliary air guide plate 9 is located at the extended position, and at this time, the auxiliary air guide plate 9 extends downward, the auxiliary air guide plate 9 may extend in the vertical direction, the auxiliary air guide plate 9 may also extend downward obliquely, and the wind of the air outlet 31 may be guided downward by the combined action of the auxiliary air guide plate 9 and the main air guide plate 8, so that the blown hot wind may better reach the ankle position of the human body, and the comfort in the heating mode is improved.
Alternatively, referring to fig. 1 to 3 and 5, the bottom surface of the cabinet 1 is formed with a receiving groove 13 adapted to receive the auxiliary air guide plate 9, and the auxiliary air guide plate 9 is received in the receiving groove 13 when the auxiliary air guide plate 9 is rotated to the receiving position. Thereby, the storage of the auxiliary air deflector 9 is facilitated by the storage groove 13 provided, so that the air conditioner 100 is more compact in structure and more attractive in appearance. Alternatively, the bottom surface of the casing 1 may be formed with a limiting protrusion 12, and the opening end of the volute 3 in the casing 1 may extend to the outside of the casing 1, and the receiving groove 13 is defined between the limiting protrusion 12 and the volute 3.
Further, referring to fig. 1 to 3 and 5, a portion of the bottom wall 131 of the receiving groove 13 is recessed upward to form a relief space 132, one end of the auxiliary air guide plate 9 is accommodated in the relief space 132 when the auxiliary air guide plate 9 is in the deployed position, and the other end of the auxiliary air guide plate 9 is rotated downward. Therefore, through the avoidance space 132, the auxiliary air deflector 9 is convenient to rotate, and when the auxiliary air deflector 9 is in the unfolding position, the auxiliary air deflector 9 can be positioned at a higher position, and the utilization rate of the space below the auxiliary air deflector 9 is improved. Here, the open end of the receiving groove 13 is directed downward, and the bottom wall 131 of the receiving groove 13 is a wall corresponding to the open end of the receiving groove 13.
Alternatively, referring to fig. 1 to 3 and 5, when the scroll casing 3 is disposed in the casing 1, a support rib 33 may be disposed on an outer wall surface of the scroll casing 3, the support rib 33 extends toward the escape space 132, and a free end of a bottom wall of the escape space 132 (the bottom wall of the escape space 132 is opposite to an open end of the receiving groove 13) is supported on the support rib 33.
