| Zusammenfassung: | The embodiment of the invention provides a fan, which comprises a rotor, a fan blade and a motor, a stator disposed so as to face the rotor; an impeller that is attached to the rotor and rotates together with the rotor; a tower part for supporting the stator; and a support part disposed on the opposite side of the rotor in the axial direction and provided in cooperation with the tower part, the support part having: a base part attached to the tower part; the outer ring part is arranged on the outer side of the base part in the radial direction, an air suction opening is formed between the outer ring part and the base part, and an air guide part is arranged on the inner circumference of the outer ring part in the radial direction. According to the draught fan, by arranging the air guide part, on one hand, airflow entering from the air suction opening can be guided, on the other hand, airflow in the draught fan is prevented from flowing out from the air suction opening, and therefore the air suction efficiency |
