  • Patent number: 10244918
    Abstract: Provided are a dish washing machine capable of effectively removing garbage which remains at the bottom of a washing tub and a filter and a method of controlling the same. When washing water is sprayed from a nozzle while a vane is positioned at a reference position during a drainage operation, since a deflection angle of the vane is bent back and the washing water is strongly sprayed toward a rear wall of a washing tub, the washing water may form a fast and strong water current over a bottom plate of the washing tub, and the fast and strong water current may remove garbage which remains at a filter while flowing over the bottom of the washing tub. Also, even when an excessive amount of garbage is accumulated at a filter at a top end of a sump and blocks the filter during a washing operation such as preliminary washing, main washing, etc., the filter is automatically washed using a small amount of water, thereby eliminating inconvenience of a user to directly separate and wash the filter.

  • Patent number: 10004114
    Abstract: An induction heating cooker includes a plurality of heating coils to heat a container, an inverter having a plurality of switching elements to be operated such that a high-frequency voltage is selectively supplied to the plurality of heating coils, and a control unit to control the operations of the plurality of switching elements such that the high-frequency voltage is time-divisionally supplied to a heating coil, on which the container is positioned, among the plurality of heating coils. By this configuration, it is possible to reduce the number of inverters and manufacturing costs. In addition, since the thickness of the cooker is reduced, it is possible to reduce the overall size of the cooker.

  • Patent number: 9986884
    Abstract: Provided are a dish washing machine and a controlling method thereof. When water is sprayed from a nozzle while a vane is positioned at a reference position during a drainage operation, since a deflection angle of the vane is bent back and the water is sprayed toward a rear wall of a washing tub, the water forms a fast and strong water current over a bottom plate of the washing tub to remove garbage which remains at a filter while flowing over the bottom of the washing tub. Accumulation at a filter at a top end of a sump and that may block the filter during washing such as preliminary washing, main washing, etc., is washed, thereby eliminating the inconvenience of having to separate and wash the filter, and effectively improves performance by avoiding poor circulation of water that may occur due to a filter blockage or generation of bubbles.
