Abstract: A washing machine, which can simply and reliably remove stains on an outer circumferential surface of a washing drum forming a dewatering drum and greatly increase the assembling efficiency and the space efficiency by reducing common used components The washing machine includes: a closed bottomed cylindrical first washing drum forming a housing of a washing machine body and having an upper opening; a closed bottomed cylindrical second washing drum disposed in a specified distance from an inner circumferential surface of the first washing drum and inside the first washing drum in a freely rotating manner and serving as a dewatering drum; a circular plate portion having stirring wings extending radially outwardly of the second washing drum and integrally formed with the second washing drum; and an electric motor driving the second washing drum and the circular plate portion to rotate together.

Abstract: A washing machine, including: a washing and dewatering drum for containing washings; an impeller configured at a bottom of the washing and dewatering drum in a free rotation manner; a circulating water path formed on a side surface part of the washing and dewatering drum and configured to enable water delivered by rotation of the impeller to flow from bottom to top; and a filter unit mounted on the circulating water path and configured to suck from an inflow port the water returning into the washing and dewatering drum from the circulating water path and enable the water to flow through to collect lint and the like contained in the water.

Abstract: A device and a washing machine are disclosed. The device includes: a main body mounted on an inner circumferential face of the washing tank; an intake port provided at a lower end portion of the main body; a waterway; and an exhaust port provided on a surface of an upper end portion of the main body. Water is guided through the waterway so as to be exhausted from the exhaust port and splashed onto laundry in the washing tank. The exhaust port is relatively long in a circumferential direction Y of the inner circumferential face, a top-to-bottom width of the exhaust port in the middle is narrower than that at both ends in the circumferential direction Y, and a groove on the surface of the main body is adjacently arranged on two outer sides of the exhaust port in the circumferential direction Y.

Abstract: Provided are an opening and closing structure, a component, and a washing machine. The opening and closing structure includes: a supporting body formed with an opening part; and the lid supported by the supporting body in a free rotation manner. An elastic deformation part forming a rotation center and a periphery of the lid has flexibility. One of the supporting body and the elastic deformation part is provided with a shaft forming the rotation center of the lid, and the other is provided with a hole insertable by the shaft. One of the supporting body and the elastic deformation part is provided with a pin, and the other is provided with a recess receivable to the pin with a clearance during opening and closing of the lid. The recess gradually becomes shallower as the lid goes from an open position to an opposite side of a closed position.
