Abstract
(EN)
Disclosed in the present application are a cross-flow air duct structure, a fan heater, and an air conditioner having the cross-flow air duct structure. The cross-flow air duct structure comprises a volute casing, a panel, an air inlet, and an air outlet; a cross-flow fan blade is provided in the volute casing; the panel and the cross-flow fan blade are unequally spaced; the minimum spacing between the panel and the cross-flow fan blade is L; an air guide structure is provided on the panel. The cross-flow air duct structure of the present application is applicable to the fan heater. In the present application, an air guide apparatus is locally added so as to promote outflow of a cross-flow air duct volute tongue to return to a cross-flow area at an appropriate position in advance, thereby improving the air volume of a cross-flow fan and achieving the purpose of improving efficiency; a high-speed airflow at the volute tongue reenters the cross-flow area as soon as possible so as to shorten an acting time between the high-speed airflow at the position and the panel and reduce abnormal noise caused by rotor-stator interaction to the maximum extent.

La présente invention concerne une structure de conduite d'air à écoulement tangentiel, un radiateur soufflant et un climatiseur pourvu de la structure de conduite d'air à écoulement tangentiel. La structure de conduite d'air à écoulement tangentiel comprend une volute, un panneau, une entrée d'air et une sortie d'air ; une pale de ventilateur tangentiel est agencée dans la volute ; le panneau et la pale de ventilateur tangentiel sont espacés inégalement ; l'espacement minimal entre le panneau et la pale de ventilateur tangentiel est égal à L ; une structure de guidage d'air est agencée sur le panneau. La structure de conduite d'air à écoulement tangentiel de la présente invention peut être appliquée au radiateur soufflant. Selon la présente invention, un appareil de guidage d'air est ajouté localement afin d'amener l'écoulement de sortie d'une languette en spirale de la conduite d'air à écoulement tangentiel à retourner vers une zone d'écoulement tangentiel à une position appropriée à l'avance, ce qui permet d'améliorer le volume d'air d'un ventilateur tangentiel et d'atteindre l'objectif d'amélioration de l'efficacité ; un écoulement d'air à grande vitesse, au niveau de la languette en spirale, entre de nouveau dans la zone d'écoulement tangentiel dès que possible afin de raccourcir un temps d'action entre l'écoulement d'air à grande vitesse au niveau de ladite position et le panneau et de réduire le plus possible le bruit anormal provoqué par l'interaction rotor-stator.

本申请公开了一种贯流风道结构、暖风机及具有其的空调器。该贯流风道结构包括蜗壳、面板、进风口、出风口,所述蜗壳内设置有贯流风叶,所述面板和所述贯流风叶之间形成不等间距的空间,所述面板与贯流风叶之间的最小间距为L,在所述面板位置设置有导风结构。本申请的贯流风道结构可以适用于暖风机中。本申请通过局部增加导风装置,促使贯流风道蜗舌出流在适当位置提前返回贯流区,从而提升了贯流风机的风量,达到了提效的目的;通过让蜗舌位置的高速气流尽快重新进入贯流区,减小该位置高速气流与面板的作用时间,最大程度降低因动静干涉引起的噪音异常。
