The invention provides a device for preparing fancy ice, which comprises an ice making box with an ice-making inner cavity; an evaporating pipe, located at the bottom of the ice-making box, for cooling the water in the ice-making inner cavity into Ice; also includes a diversion structure, provided on the ice making box, for guiding water exceeding the maximum water capacity of the ice making inner cavity to the outside of the ice making box. The device for preparing fancy ice in the present invention, when a small part of water is supplied inside the ice making box and keeps the part of the water still, the evaporating tube can completely cool the small part of water into white ice, and when it continues to cool on the surface of the white ice, When the water is supplied from above and the water flows on the surface of the white ice, the diversion structure can guide the water exceeding the maximum water capacity of the ice-making inner cavity to the outside of the ice-making box, and the evaporation tube cools the water on the surface of the white ice into a layer Transparent ice, so that fancy ice in which white ice and transparent ice are stacked can be prepared.
