Document Type and Number:
Japanese Patent JP2022104681
Kind Code:
A
Abstract:
To solve the problems that in a conventional refrigerator, it is difficult to control a power consumption of a refrigerator depending on the operating state of a heating unit, and there is a risk that bacteria in water in a water supply pipe may grow.SOLUTION: An ice maker 30 of a refrigerator 10 mainly comprises a water supply tank 31, an ice tray 32, an ice storage container 33, a water supply pump 34, a water supply pipe 35, and a heating unit 36. Then, a control unit 40 determines the presence or absence of water in the water supply tank 31 via an infrared sensor 44, and variably controls an energization rate to the heating unit 36 according to the determination content. With this structure, bacteria are prevented from growing in the water remaining in the water supply pipe, and a power consumption of the refrigerator 10 is suppressed.SELECTED DRAWING: Figure 2
