A pump motor is disclosed. The pump motor includes a case; a socket part disposed in a portion of the case and provided with a terminal part thereinside; and a cover part detachably coupled to the case and configured to open and close the socket part, wherein the socket part includes a moisture blocking member configured to block a gap between the case and the cover part.

A washing machine includes a casing, an outer tub, an inner tub, a pulsator, and a driving mechanism configured to cause rotation of at least one of the inner tub or the pulsator. The driving mechanism includes a drive motor including a stator and a rotor, a bearing housing located below the outer tub, a hollow spinning shaft coupled to the inner tub, a coupler configured to selectively connect the spinning shaft to the rotor based on moving upward and downward along an outer circumferential surface of the spinning shaft, a washing shaft located in the spinning shaft and configured to rotate the pulsator, where the washing shaft has a lower part connected to the rotor and an upper part connected to the pulsator, and an anti-friction member located between the spinning shaft and the washing shaft and configured to reduce friction between the spinning shaft and the washing shaft.

Provided is a laundry treating apparatus comprising a drum including: a drum body defining a space to store laundry therein, a front cover, a rear cover, and a drum introduction opening defined at the front cover and configured to communicate with an inside of the drum body; a drying unit configured to supply heated air to the drum body; a fixing panel; a power transmission unit including: a housing, an input shaft, an output shaft, and a gear unit disposed in the housing and configured to transmit rotational motion of the input shaft to the output shaft; a motor comprising including: a stator, and a rotor; and a heat insulation part made of a material having heat conductivity lower than heat conductivity of the housing and configured to reduce an amount of heat that is transferred from the outside of the housing to an inside of the housing.

An electric motor suitable for use in a laundry machine comprises an improved stator and/or rotor design.

A pump motor is disclosed. The pump motor includes a case; a socket part disposed in a portion of the case and provided with a terminal part thereinside; and a cover part detachably coupled to the case and configured to open and close the socket part, wherein the socket part includes a moisture blocking member configured to block a gap between the case and the cover part.

A washing machine comprises a cabinet, a washing drum rotatably arranged in the cabinet, wherein the washing drum is a water holding drum to accommodate washing water, a water drainage channel which discharges water from top to bottom is arranged at an inner side of a peripheral wall of the washing drum, an upper end of the water drainage channel communicates with the inside of a washing drum, and a lower end communicates with the outside of the washing drum. The water drainage channel comprises a water channel casing and at least part of a washing drum wall, and one side, facing the washing drum wall, of the water channel casing is provided with a cut-through groove, the water channel casing is fastened on the washing drum wall, and forms a water flow channel together with the washing drum wall.

Disclosed herein is a washing apparatus includes a drum, a pulsator, a drum drive motor rotates the drum in a first direction or a second direction, a pulsator drive motor rotates the pulsator in the first direction or the second direction, and a controller controls the drum drive motor to rotate the drum in the first direction and to rotate the drum in the second direction when an operation period expires. When a drum drive current value is greater than a first reference current value during the first direction rotation of the drum, the controller controls the drum drive motor so that the drum drive motor stops rotating the drum in the first direction. When the operation period expires the controller controls the drum drive motor so that the drum is rotated in the second direction.

A pump motor is disclosed. The pump motor includes a case; a socket part disposed in a portion of the case and provided with a terminal part thereinside; and a cover part detachably coupled to the case and configured to open and close the socket part, wherein the socket part includes a moisture blocking member configured to block a gap between the case and the cover part.

A laundry appliance includes a drum rotationally positioned within a structural cabinet. An impeller is rotationally positioned within the drum. The impeller is selectively and independently operable with respect to the drum. A binary motor has a first motor and a second motor disposed within a common housing. A first drive belt extends between the first motor and the drum. A second drive belt extends between the second motor and the impeller. The first and second motors engage the first and second drive belts on a belt side of the common housing.

By improving the rigidity of a pulley while suppressing a weight of the pulley from increasing, excessive noises due to resonance can be reduced. A washing machine 1 includes a drum 9 rotatably disposed in the water tub 5. The washing machine 1 has a motor to rotationally drive a pulley 20, which is fixed to the drum 9, via an endless belt 13. The pulley 20 has a plurality of arms 23 radially extend from the boss 22 to support an outer wheel 21. The arm 23 has a variable cross-sectional portion 24 in which a section modulus against bending in an axial direction gradually decreases from the boss 22 to the outer wheel 21.
