The invention relates to an ice maker. A shell of the ice maker is provided with an ice-making mechanism in which a reversible ice-making box is arranged. A refrigeration circulation mechanism comprises a compressor, a condenser, an evaporator and corresponding pipelines; a water-supplying system is provided with a water tank, an evaporator is arranged in the ice-making box and an ice-receiving mechanism is arranged beneath the ice-making box. The ice-receiving mechanism comprises: an ice-storing box arranged under the ice-making box, a water tank arranged under the ice-storing box and a water-pouring port arranged at the upper end of the ice-making box. When the ice-making box is turned downwards, the water-pouring port is always kept at the lowest position of the downward side of the ice-making box, and a water flowing channel is arranged beneath the water-pouring port. When the ice-making box is driven by a motor to turn upside, the water in the ice-making box flows from the water-pouring port into the water tank, therefore the water is separated from the ice. The ice maker omits the ice-shoveling plate and other relevant parts of the existing ice maker, therefore the structure of the ice maker is simple and simultaneously the defects of easily being blocked when the ice-shoveling plate is working can be avoided.
