A method of treating dishware in a domestic automatic dishwashing machine for from 30 minutes to 50 minutes includes washing the dishware for from 15 minutes to 30 minutes and rinsing the dishware for from 15 minutes to 30 minutes. Washing the dishware includes dosing from 2.0 litres to 5.0 litres of water into a cleaning chamber of the domestic automatic dishwashing machine and contacting the dishware in the cleaning chamber with the wash water. At least 10 minutes of washing the dishware is carried out at a temperature ranging from 40° C. to less than 50° C. Rinsing the dishware includes dosing from 2.0 litres to 5.0 litres of rinse water into the cleaning chamber and contacting the dishware in the cleaning chamber with the rinse water. At least 7 minutes of rinsing the dishware is carried out at a temperature ranging from 55° C. to 65° C.

Induction cooker

An induction cooker according to the present disclosure includes a body including a top plate on which a heating target is placed, a frame formed to surround an outer periphery of the top plate, and having a discontinuous portion being electrically discontinuous from other parts of the frame, a heating coil disposed below the top plate, and configured to inductively heat the heating target, a driver circuit configured to supply electric power to the heating coil, a power transfer coil configured to transfer electric power by magnetic resonance, and a power transfer circuit configured to supply electric power to the power transfer coil, and a power receiving device including a power receiving coil configured to receive electric power from the power transfer coil by magnetic resonance, and a load circuit configured to operate by the electric power received by the power receiving coil.

Washing machine

An inner drum cover is provided at a drum opening of an inner drum of a washing machine, the inner drum cover is used to open or close the drum opening, so that the inner drum forms a closed container after the drum opening is closed by the inner drum cover. The inner drum can perform washing after the inner drum cover is correspondingly fastened to the drum opening, so that clothes only come into contact with washing water in the sealed inner drum in a washing process. In this way, a case in which the clothes are contaminated because washing water between the inner drum and an outer drum flows into the inner drum is avoided, washing cleanliness of the washing machine is greatly improved, and incomplete washing of the clothes caused by contamination of the washing water between the inner drum and the outer drum is avoided.

ELECTRIC RANGE
20220400540 · 2022-12-15 ·

An electric range is provided that may effectively increase output of a heater by optimizing a shape of each ferrite core without increasing a number of ferrite cores and may secure a maximum area of a through hole that facilitates communication between an inside and outside of a core frame, thereby preventing overheating of the heater and decreasing a use time of the heater.

Washing machine driving device, and washing machine and driving method using same
11525204 · 2022-12-13 · ·

Provided are an apparatus for and a driving method of driving a washing machine in which a washing tub is rotated by an inertial force in a freewheeling condition or at a low power driving mode, and a pulsator is reversely rotated, in a state where the pulsator and the washing tub are rotated in one direction. When driving the pulsator and the washing tub in the opposite directions, the inner rotor and the outer rotor are driven in a first direction where the washing tub is rotated, to then set the inner rotor to any one of a free-wheeling mode, an intermittent driving mode, and a low power driving mode, to thus rotate the washing tub, and the outer rotor is driven in one direction opposing the first direction to thus reversely rotate the pulsator.
