  • Patent number: 9410547
    Abstract: A compressor includes a casing configured to store lubricating oil in a bottom part, and a compression mechanism accommodated in an interior of the casing. Lubricating oil is separated out from high-pressure refrigerant discharged from the compression mechanism. Lubricating oil separated out by the oil separator flows from a high-pressure space formed in the interior of the casing and into which the high-pressure refrigerant flows. An ejector mechanism is disposed in the interior of the casing, preferably in the high-pressure space. The ejector mechanism includes a refrigerant-accelerating flow path in which the high-pressure refrigerant flows via a narrowed part in order to increase a flow rate of the high-pressure refrigerant, and an oil suction flow path merging with the refrigerant-accelerating flow path.

  • Patent number: 9335087
    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thereof; a tray accommodation portion having opened upper and lower surfaces, and configured to be inserted into or withdrawn from the case through the opening; an ice tray accommodated in the tray accommodation portion, and containing water to be frozen to ice cubes; and an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.

  • Patent number: 9273890
    Abstract: An ice making assembly and method utilizes a housing having an upper fluid chamber, a plurality of distinct, substantially vertical fluid channels, and at least one drain aperture in fluid communication with a fluid reservoir. Ice forming members extend from an ice forming evaporator into respective fluid channels. During an ice making event, fluid continuously supplied to the upper fluid chamber flows into each of the fluid channels and out through at least one drain aperture into a fluid reservoir below. The ice forming members are cooled such that fluid flowing across the fluid channels freezes on the ice forming members over time, forming clear ice pieces. The ice pieces are subsequently released from the ice forming members and transferred for storage and/or dispensing.
