Abstract
(EN)
An air duct structure (600), comprising a volute (610), an air guide shell (620), and an exhaust coil (630), an air output end of the volute (610) being in communication with an air intake end of the air guide shell (620), and an air blocking plate (611) being arranged on the peripheral ring edge of the volute (610); an air output end of the air guide shell (620) is in communication with an inner side curved surface of the exhaust coil (630); and the peripheral ring of the exhaust coil (630) is provided with air guide plates (631), the air guide plates (631) being arcuate structures bending uniformly to the same side.
(FR)
La présente invention concerne une structure de conduite d'air (600), qui comprend une volute (610), une enveloppe de guidage d'air (620), et une spirale d'échappement (630), une extrémité de sortie d'air de la volute (610) étant en communication avec une extrémité d'admission d'air de l'enveloppe de guidage d'air (620), et une plaque de blocage d'air (611) étant agencée sur le bord de bague périphérique de la volute (610) ; une extrémité de sortie d'air de l'enveloppe de guidage d'air (620) est en communication avec une surface incurvée de côté intérieur de la spirale d'échappement (630) ; et la bague périphérique de la spirale d'échappement (630) est pourvue de plaques de guidage d'air (631), les plaques de guidage d'air (631) étant des structures arquées qui se courbent uniformément vers le même côté.
