Abstract: The embodiments of the present disclosure provide a heating control method, a heating control device, and an ice maker. The heating control method comprises: determining that the ice maker is in an ice-making operation state; acquiring a first heating strategy of a target part of the ice maker according to a preset first heating strategy acquisition rule, based on ambient parameter information of an ambient in which the target part of the ice maker is located; and heating the target part based on the first heating strategy. Through the embodiments of the present disclosure, the problem that the deicing heating control technology of the ice maker in the prior art has high energy consumption is solved, and the beneficial effect of precise and low-energy deicing heating control on the ice-prone parts of the ice maker is achieved.

Abstract: A refrigerator is provided that includes a low energy refrigerator heat source. The refrigerator includes a heat source positioned at a source of latent heat. The heat source harvested heat from the source of latent heat and stores said heat in a fluid within that heat reservoir or heat exchanger. The warmed fluid is then supplied via a fluid pathway to an application requiring a heat output. Thus, the heat reservoir provides heat to the application without use of an energy-consuming device, which reduces the energy consumption of the refrigerator.

Abstract: An ice-making device for a refrigerator including a duct providing a cold air flow path under an ice tray in which water turns into ice pieces. Uneven portions extending in a direction differing from a flow direction of cold air are formed at a lower surface of the ice tray. The duct may have a wavy surface. The surface features of the ice tray and the duct can advantageously increase contact area and contact time between cold air and the ice tray, thereby increasing the heat exchange efficiency between cold air and water contained in the ice tray.

Abstract: A refrigerator includes an ice tray, a motor, an ejector including a rotary shaft and a protrusion pin, and a heater for selectively supplying heat to the ice tray. A control method of the refrigerator includes a first step of sensing whether the ejector is rotated to reach a first setup position; a second step of driving the heater and stopping driving of an ice making compartment fan if the first step is satisfied; a third step of determining whether the ejector is rotated to reach a second setup position; and a fourth step of stopping driving of the heater if the third step is satisfied, and wherein the ejector continues to be rotated while the second to fourth steps are implemented.
