Abstract: A flow guide structure for a bladeless air fan. The bladeless air fan includes a host and an airflow guiding frame. The host includes an airflow generator. The airflow guiding frame is connected to the host and includes an air discharging portion which has an airflow guiding passage inside to communicate with the airflow generator. The air discharging portion also includes an airflow gathering wall, an inner ring compression wall and an outer ring compression wall extended forwards from two ends of the airflow gathering wall. From the junctions of the airflow gathering wall and inner ring compression wall and outer ring compression wall, the inner ring compression wall and outer ring compression wall are spaced from each other at a decreasing interval between them, and the inner ring compression wall and outer ring compression wall also have distal ends forming a front air outlet to discharge airflow forwards.

Abstract: A bladeless air fan includes a host and an airflow guiding frame. The host divides into a housing section to hold an airflow generator and a pivoting section to include two first pivoting portions. The airflow generator is connected to an airflow guiding manifold extended from the housing section to the pivoting section. The airflow guiding frame includes an air discharging portion and an airflow guiding passage and two second pivoting portions being annular to form two air intake ports communicating with the airflow guiding passage. The second pivoting portions are rotatably coupled with the first pivoting portions such that the airflow guiding passage communicates with the airflow guiding manifold. The air discharging portion encircles an airflow passage being formed at an inner diameter allowing the housing section to pass through to enlarge the range of the second pivoting portions rotating against the first pivoting portions.

Abstract: A steam-cleaning appliance of the invention comprises a housing in which a water storage chamber, a pump, and a steam device are mounted. The pump pumps cold water from the water storage chamber and delivers cold water to the steam device. The steam device includes a water-flowing path and a heating unit that heats water flowing through the water-flowing path. Cold water pumped by the pump penetrates into the water-flowing path via a water inlet to be heated. The increasingly heated water is sputtered into steam through a steam pipe to a nozzle of the steam-cleaning appliance.
