Abstract: A method for producing a hot-rolled steel sheet which enables predicting a temperature history of unevenness of the end face of a coil includes: measuring a surface temperature of hot-rolled strip-shaped steel; calculating a temperature history in a natural cooling state after coiling, assuming that the strip-shaped steel has been coiled without unevenness on an end face, based on the surface temperature measured in the measurement step; actually coiling the strip-shaped steel after the measurement step; scanning with a displacement meter, an end face of a coil formed in the coiling step, and deriving a size of the unevenness of the end face over a radius of the coil; and predicting a temperature history of the unevenness in a natural cooling state using: the temperature history calculated in the first calculation step; and the size of the unevenness derived in the derivation step.

Abstract: Provided is a drum washing machine. The drum washing machine, which is provided with a rotating body on the rear a drum, is able to smoothly switch between a first form in which the drum and the rotating body rotate independently and a second form in which the drum and the rotating body rotate integrally. When switching from a biaxial driving form to a uniaxial driving form and vice versa, a control part rotates a rotor clockwise and anticlockwise in a manner of taking a reverse action 1 and a reverse action 2 during the operation of a torque motor, i.e., during an action of moving a clutch body by virtue of a moving mechanism. The reverse action 1 includes an action of stopping the rotor rotating clockwise direction, and the reverse action 2 includes an action of stopping the rotor rotating anticlockwise.

Abstract: The present disclosure reduces sound generated when a driving mode of a drum washing machine having a rotating body on a rear part of a drum is switched between a first mode and a second mode. The first mode is a driving mode in which the drum and the rotating body independently rotate, and the second mode is a driving mode in which the drum and the rotating body integrally rotate. A bearing-side cushioning member is arranged on a clutch carrying plate side. The bearing-side cushioning member firstly touches an object side when a spline of a clutch body is engaged with a spline of the clutch carrying plate, so as to reduce an impact force generated between the clutch body and the clutch carrying plate.

Abstract: A drum washing machine, including: a driving part, capable of operating in a uniaxial driving form and a biaxial driving form; a heater configured to heat water stored in the outer drum for washing; and a control part which at least performs washing operation of a first washing mode and a second washing mode. In a washing process of the first washing mode, the control part enables the driving part to operate in the uniaxial driving form and also enables the heater to operate. Further, in a washing process of the second washing mode, the control part enables the driving part to operate in the biaxial driving form and also enables the heater to operate in such a manner that heat applied to the water is reduced compared with the first washing mode.

Abstract: A washing machine is provided. The washing machine includes: a washing tub having an axis extending longitudinally; a circulation path configured to draw detergent solution mixed with a detergent in the washing tub and return the detergent solution into the washing tub from an upper side; a pump configured to pump the detergent solution in the washing tub into the circulation path and allow the detergent solution to rise in the circulation path; and a controller configured to execute a washing operation. The washing operation includes a circulation-soaking process during which a circulation process and a soaking process are conducted alternately and repeatedly. The detergent solution is circulated between the washing tub and the circulation path by driving the pump and sprayed onto washings in the circulation process. The pump is stopped from being driven and, the washings are soaked with the detergent solution in the washing tub in the soaking process.

Abstract: Provided is a washing machine. The washing machine includes: a washing drum accommodated in an outer drum 3; a motor for rotating the washing drum; a water tank for receiving detergent water containing detergents from the outer drum; a circulating path for taking the detergent water and injecting the detergent water from an upper side into the washing drum; a pump for taking the detergent water in the water tank into the circulating path and lifting the detergent water in the circulating path; and a control part for executing a washing operation including a dewatering washing process. In the dewatering washing process, circulating treatment, impregnation treatment and dewatering treatment are repeatedly conducted.

Abstract: Disclosed is a drum washing machine, including: a drum configured in an outer tank and capable of rotating by using an inclination axis as center; a stirring body configured at a rear part of the drum and including main blades in contact with washings; a driving unit enabling the drum and the stirring body to rotate at different rotating speeds; and a water supply mechanism part configured to splash water to a surface of the stirring body. The water supply mechanism part includes a first water storage part capable of moving between a position in water soaked in the outer tank and a position higher than the water and storing water when soaked in water of the outer tank, and a first outflow port capable of enabling water stored in the first water storage part to flow out to the surface of the stirring body at an upper position.

Abstract: The present invention provides a washing machine capable of suppressing vibration and noise and capable of reducing a gap between a circumferential wall of an outer tub and a housing so as to reduce a useless space. The washing machine includes a box-shaped housing having an internal space opened upward; and a washing tub unit suspended and supported through a hanger bar in the internal space. The washing tub unit includes an outer tub presented in a bottomed quasi-cylindrical shape; an inner tub presented in a bottomed quasi-cylindrical shape, coaxially configured inside the outer tub and rotatably supported by the outer tub; and a driving mechanism arranged at a lower end of the outer tub and configured to drive the inner tub to rotate.
