Abstract:
1. An ice making unit for a flow-down ice making machine, comprising an ice making portion having: an ice making plate provided at predetermined horizontal intervals with a plurality of projected rims projecting out on a front side and also extending vertically; and an evaporation tube disposed on a back face of the ice making plate opposite to the front side and meandering to have horizontally extending horizontal extensions vertically apart from each other, to generate an ice block by supplying ice making water to an ice making surface portion positioned between the projected rims in the ice making plate, wherein the ice making surface portion is provided with vertical steps of inclined portions inclined from a back side to a front side as directed downwardly from above, a lower inclination end of each inclined portion is configured to be positioned closer to the front side than an upper inclination end of an inclined portion positioned below, and the horizontal extensions of the evaporation tube are disposed to make contact with a back face of each inclined portion, the ice making portion is configured to dispose a pair of ice making plates having back faces facing each other and sandwiching the evaporation tube, and a channel for deicing water having a width narrower than a diameter of the evaporation tube is formed between upper inclination ends of back sides of inclined portions facing each other and sandwiching the horizontal extensions of the evaporation tube.
