Flow-down-type ice making machine

A flow-down-type ice making machine in which ice cubes reliably separate and drop from the lower end of an ice making plate, an ice guiding member can be placed close to the ice making plate, and the amount of ice storage is increased. An ice making section (10) is made up of a pair of ice making plates (12, 12) placed opposed to each other in a substantially vertical position and of evaporation tube (14) provided meandering between the ice making plates (12, 12). The ice guiding member (32) attached to an ice making water tank (22) is placed right under and close to the ice making section (10). The ice guiding member (32) is formed in a reverse V-shaped cross-section and is placed so that the top of the ice guiding member is located in the middle between the back sides of the ice making plates (12, 12). A slope (32a) tilting from the top of the ice guiding member (32) to one side of the top faces below one ice making plate (12), and a slope (32a) tilting from the top of the ice guiding member (32) to the other side of the top faces below the other ice making plate (12). An outwardly projecting lower end projection (20) is formed on each ice making plate (12), at the lower end of its surface facing each ice making region (12) of the ice making plate (12). Because of the presence of the lower end projection (20), an ice cube (M) running onto the lower end projection (20) is separated from an ice making surface.
