摘要： A free-of-bearing rotational positioning device for a dewatering basket of a non-treading type wringer bucket, comprising: a bucket body having a projecting seat being extended from the bottom of the bucket body toward inside; a support shaft being covered and secured by the projecting seat, the upper portion thereof jutting out of the top of the projecting seat to create a connection part; a positioning element having a conic part at the top thereof, the conic part being tapered upward, a positioning surface being formed at the bottom of the conic part and extended outward from the periphery of the support shaft; and a dewatering basket having a driven seat at the center of the bottom thereof. The bottom of the driven seat includes a shaft holder made of non-metal material. In mounting the dewatering basket, the driven seat fits from top to bottom over the connection part of the support shaft. After the lower sleeve passes through positioning element in a compression manner, the positioning surface of the positioning element is stretched into the engagement groove at the center of the shaft holder when returning to its original shape.

摘要： A powerless diversion plate of a ceiling air-conditioning circulation machine including a bearing block and a bearing within a circular inflow/outflow hole for installing a diversion disc. The diversion disc includes a plurality of radial separation pieces, and a plurality of conic and ring-shaped diversion pieces are concentrically and outwardly positioned around the connection shaft. Moreover, the diversion disc is separated by the ring-shaped diversion pieces and the radial separation pieces to create a plurality of air inflow/outflow zones. The bottom of the diversion disc has a downward protruding middle part and a staged structure at the rim thereof so as to form a -shape. In this way, it is not necessary to install a motor serving a power source. Instead, many radial separation pieces of the diversion disc serve as working surface. When an air delivery force created by the fan acts on the radial separation pieces, the diversion disc are driven in rotation at 360° such that the air to be diffused downward or sucked upward in a -shaped flowing way, thereby enhancing the air-outflowing and convection efficiency. Thus, the energy consumption and the carbon release can be reduced.

摘要： An airflow-cooling apparatus of a ceiling air-conditioning circulation machine, and more particularly a structure permitting a smooth flow of the indoor air, wherein the drawn current of air passes through a cooling apparatus and then is guided indoors for reducing the temperature. Thus, the energy consumption and the carbon release can be reduced. According to the invention, a base frame includes a base frame having a rectangular positioning frame at the rim thereof. A plurality of radial supports are extended from the periphery of the positioning frame inwards. A circular frame is positioned at the center of the base frame. The rim of the circular frame is attached to the radial supports. A fan base is positioned within the circular hole of the circular frame and supported by a plurality of ribs. A plurality of conic and ring-shaped air outflow/inflow channels are concentrically and outwardly interposed between the circular frame and the positioning frame. Moreover, a wave-shaped cooling ring frame is disposed on the circular frame. In this way, a wavy flow is ensured when the indoor air pass through the conic air outflow/inflow channels into a cooling ring frame. Thus, the structure according to the invention achieves the flowing and cooling effect.
