Abstract: The present invention relates to a fountain type of wash basin capable of improving product efficiency by simplifying the appearance of the wash basin, saving water, and enabling washing and drying by installing a water discharge outlet in the interior of a wash basin body such that the direction of discharged water is upward. The fountain type of wash basin comprises: the wash basin body having a water reservoir; and the water discharge outlet which is installed on the side surface of the lower portion of the wash basin body so as to allow tap water to be discharged in the upward direction opposite to gravity, thereby increasing the stay time of tap water in the air.

Abstract: A fin tube heat exchanger includes plate-shaped elongated fin members spaced at regular intervals, in parallel with one another. Each fin member has a fin base, through-holes in two rows in a longitudinal direction of the fin member, and raised portions with legs. Heat exchanger tubes are inserted into the through-holes. Each fin member has flat areas at a front and middle regions of a front half and a middle region of a rear half. The raised portion disposed at a rear region of the front half and a front region of the rear half has the legs inclined by a predetermined angle with respect to a traverse centerline which passes through the center of an adjacent through-hole of the front row. The distance from the centerline generally increases with a direction of airflow. A larger volume of air can be directed toward the vicinity of the tubes of the rear row. Each fin member has a front edge and a rear edge.
