  • Patent number: 11285441
    Abstract: According to one embodiment of the present invention, a control method for a water purifier comprises the steps of: filtering inflowing water so as to generate purified water; extracting the generated purified water; measuring the flow rate of the purified water extracted per unit time; flushing a filter part by using purified water generated in the filter part, when the extraction of the purified water is complete; and draining the flushed water to the outside through a residential water outlet of the filter part, wherein, in the purified water generation step, discharging of residential water generated in the purified water generation step is blocked according to the accumulated flow rate during a one-time extraction of the purified water, calculated on the basis of the flow rate of the purified water.

  • Patent number: 9844303
    Abstract: A gear reducer and a juicer including the gear reducer are disclosed. The gear reducer transfers rotational force, provided by a drive unit, to a juice extraction screw assembly after gear reduction. The gear reducer includes one or more gear reduction units. At least one of the one or more gear reduction units includes a sun gear coaxially connected to a rotating shaft of the drive unit; a ring gear configured such that a plurality of gear teeth are formed on the inner circumferential surface thereof around the sun gear, and configured to output a rotation speed slower than the rotation speed of the sun gear; and a plurality of planetary gears disposed between the sun gear and the ring gear, and configured to transfer the rotational force of the sun gear to the ring gear.
