Abstract

The present invention relates to an unattended-cooking rice cooker device in which cooking ingredients such as rice or other grains are supplied, cleaned, and cooked and, more specifically, to an unattended-cooking rice cooker device comprising: a supply unit that divides and stores the cooking ingredients to supply the cooking ingredients; a cleaning unit that receives the cooking ingredients supplied from the supply unit and cleans the cooking ingredients supplied therein while forwardly and backwardly rotating; and a cooking unit including a rice cooker that receives and cooks the cooking ingredients cleaned in the cleaning unit, so as to automatically perform the cleaning and cooking of the ingredients. At the same time, a cleaning drum unit of the cleaning unit can be used as a lid (cap) of the cooking unit including the rice cooker, and thus the number of components can be reduced. In addition, the heat during the cooking is transferred into the cleaning unit to improve hygiene conditions in the cleaning unit.

a cooker (300) installed under the washer (200) to heat and cook the cooking ingredient supplied from the washer (200), wherein
the feeder (100), the washer (200), and the cooker (300) slide in along a side surface of a housing (400) including a feeder shelf (410), a washer shelf (420), and a cooker shelf (430), wherein
the feeder (100), the washer (200), and the cooker (300) are vertically arranged such that the cooking ingredient moves by gravity from the feeder (100) to the washer (200) and from the washer (200) to the cooker (300),
the washer (200) includes an inlet slot (211) through which the cooking ingredient is introduced from the feeder (100) and a hollow washing drum (210) for washing the cooking ingredient, wherein
wherein the washing drum (210) is rotatable to discharge the cooking ingredient through the inlet slot (211) by rotating the inlet slot (211) downward, wherein
an inner pot body (310) in the cooker (300) receiving the cooking ingredient from the washing drum (210) is spaced apart from a bottom of the washer shelf (420), wherein
the washing drum (210) is spaced apart from a top of the washer shelf (420) having a curve corresponding to an outer shape of the washing drum (210),
wherein the inlet slot (211), which is an opening formed in a top of the washing drum (210), serves as both an inlet for receiving the cooking ingredient and an outlet for discharging the cooking ingredient into the inner pot body (310) by being rotated downward after washing, after washing, the washing drum (210) is rotated downward to the inner pot body (310);
wherein
during cooking, the washing drum (210) is pressed down and lowered by a pressurizer to come in tight contact with the washer shelf (420), and the inner pot body (310) is pressed and lifted by a traction driver (330) to come in tight contact with the washer shelf (420) so that the washing drum (210) serves as a lid of the inner pot body (310), and whereby heat from the inner pot body (310) during cooking is transferred to the washing drum (210) to evaporate moisture therein.
