  • Refrigerator having an ice making device in which an ice tray rotates upside down in a tray accommodating portion
    Patent number: 10047995
    Abstract: A refrigerator having an ice making device, comprises: a case having an opening at one side thereof; a tray accommodation portion having opened upper and lower surfaces, and configured to be inserted into or withdrawn from the case through the opening; an ice tray accommodated in the tray accommodation portion, and containing water to be frozen to ice cubes; and an accommodation portion coupling unit for coupling the tray accommodation portion to the case. Water is poured onto the ice tray in a state that the ice tray has been accommodated in the tray accommodation portion, and then the ice tray is carried to be mounted to the case. This may solve the conventional problem that each ice tray has to be carried. Furthermore, since an external force such as hand trembling is transmitted to the ice tray via the tray accommodation portion, overflow of water is minimized.
