Title:
ICE-MAKER
Document Type and Number:
Japanese Patent JP2019078466
Kind Code:
A
Abstract:
To attain reduction of cost by reducing the number of components as further as possible in an ice-maker that alternately and iteratively executes an ice-making operation and a deicing operation.SOLUTION: An ice-maker 10 is configured to make ice by alternately and iteratively executing an ice-making operation and a deicing operation in an ice-making part 11. An electronic expansion valve of which the opening is adjusted by control of a control device 40 is adopted to an expansion valve 33 of a freezer 30 that cools the ice-making part 11, and an entrance part temperature sensor 37 and an exit part temperature sensor 38 are provided in a coolant entrance part 34a and a coolant exit part 34b of an evaporator 34 in the ice-making part 11. The control device 40 controls the opening of the expansion valve due to detected temperatures of the entrance part temperature sensor 37 and the exit part temperature sensor 38 while the ice-making operation is executed, and detects at least either ice-making is completed in the case of the ice-making operation or deicing is completed in the case of the deicing operation due to a detected temperature of at least one of the entrance part temperature sensor 37 and the exit part temperature sensor 38.SELECTED DRAWING: Figure 1
