The washing machine includes a tub mounted in a cabinet, a drum mounted in the tub, a shaft that transmits a driving force from a motor to the drum, front and rear bearings mounted on an outer circumference of opposite end portions of the shaft, a bearing housing built in a central portion of a rear wall of the tub to support the front bearing, a rotor coupled to the rear end portion of the shaft, a stator fixed to the tub rear wall inward of the rotor, and a connector of the rotor that serration coupled to the outer circumference of the shaft in front of the rear bearing so as to transmit rotating power from the rotor to the shaft. A bearing bracket may be fixed to the rear wall of the tub so as to cover an outside of the rotor and support the rear bearing.

Method of forming a drum type washing machine having a driving unit

A tub having a structurally strengthened rear wall and a washing machine with the same therein are disclosed. A washing machine includes a bearing housing having a flange part and a tub injection-molded with the bearing housing inserted into a wall thereof, the wall having a recessing part and a projecting part formed on an inner or an outer surface thereof along a circumferential direction, and a circumferential rib or a radial rib formed on the recessing part.

Tub having structurally strengthened rear wall and washing machine with the same therein

A washing machine includes a tub made of plastic to store water therein and a drum rotatably installed in the tub to hold laundry therein. A shaft passes through the tub and connects to the drum to transmit driving power from a motor to the drum. A wall having a recessing part and a projecting part is formed on an inner surface or outer surface thereof in a circumferential direction. A bearing housing has a stator fastening part where the stator fastening part has a recessing part and a projecting part corresponding with the recessing part and the projecting part of the wall in a circumferential direction, and a stator of the motor is mounted on the stator fastening part and a rotor of the motor is connected to a rear part of the shaft and surrounding the stator.

A washing machine includes a bearing housing having a flange part and a tub part injection-molded with the bearing housing inserted into a wall thereof, the wall having a recessing part and a projecting part formed on an inner or an outer surface thereof along a circumferential direction, and a circumferential rib or a radical rib formed on the recessing part.

A washing machine

A washing machine and an operating method of the washing machine are provided. In the operating method of the washing machine, it is determined whether a washing machine has a regular laundry load or a single laundry load based on the amount of laundry and the number of times of detection of the amount of laundry. Therefore, it is possible to precisely determine the laundry load of a washing machine, reduce the time taken to determine the laundry load of a washing machine, and prevent a washing machine from being damaged by a misreading of the laundry load of a washing machine.

Washing machine and operating method thereof

A drum type washing machine is provided. The washing machine includes a tub mounted in a cabinet, a drum mounted in the tub, a shaft that transmits a driving force from a motor to the drum, front and rear bearings mounted on an outer circumference of opposite end portions of the shaft, a bearing housing built in a central portion of a rear wall of the tub to support the front bearing, a rotor coupled to the rear end portion of the shaft, a stator fixed to the tub rear wall inward of the rotor, and a connector of the rotor that serration coupled to the outer circumference of the shaft in front of the rear bearing so as to transmit rotating power from the rotor to the shaft. A bearing bracket may be fixed to the rear wall of the tub so as to cover an outside of the rotor and support the rear bearing.

Structure of driving unit in drum type washing machine

A laundry treatment apparatus is provided that includes a condensing pool disposed within a water supply port formed in a tub, a water supply passage formed between the condensing pool and the water supply port, and a cap that guides water to the condensing pool and stops steam flowing backward through the water supply passage so that the steam is introduced into the condensing pool. The steam flowing backward from an inside of the tub to the water supply port of the tub is brought into contact with the water contained in the condensing pool and is condensed, thereby preventing pollution of a detergent holder or peripheral portions thereof, which may occur when the steam flows backward into the detergent holder or peripheral portions thereof via the water supply port of the tub.

Laundry treatment apparatus and control method thereof

A washing machine having height adjustable legs is provided. The washing machine may include a base provided at a bottom of the washing machine, a plurality of legs coupled to the base, and an over-unscrewed prevention member provided with each leg. Each leg may include a bolt that is height-adjustably assembled at the base. The over-unscrewed prevention member may be provided at the bolt of each leg and caught by the base when the legs are unscrewed so as to set a maximum unscrew height of the legs.

Washing machine

A defrosting method of a drum-type washing machine is provided. The defrosting method includes performing a warm water supply operation upon receiving a defrost command; performing a water discharge operation; performing a heating operation if a water level has not yet decreased; and performing an additional water discharge operation.

Defrosting method of drum-type washing machine

An automatic level controlling apparatus () for supporting an appliance includes a hollow leg body (), a piston () inserted in the hollow leg body (), a spring () seated on an upper portion of the piston (), a cap () disposed on an upper portion of the piston () to support an upper portion of the spring (), a frictional member () disposed around the piston (), and a piston rod () coupled to the piston () and supported on a floor.

Automatic level controlling apparatus

A washing machine and a controlling method thereof are provided. The washing machine and controlling method use a sensor to sense a load of laundry at a predetermined point during a wash cycle, and controls the rotating speed of a drum based on whether the sensed load of laundry is a small load or a single article, in order to untangle laundry and implement a spin cycle.

Washing machine and controlling method of the same

An automatic height adjustment leg of a laundry handling apparatus according to the present invention comprises a cylinder mounted to a base of a laundry handling apparatus; a piston movably arranged inside the cylinder; a elastic member installed in the cylinder so as to elastically support the piston; and a leg penetrating the cylinder and fixed to the piston. There are provided advantages that the horizontality of the laundry handling apparatus may be automatically adjusted as the piston and leg move on and vibration may be absorbed and reduced by the elastic member.

Automatic height adjustment leg of laundry handling apparatus and laundry handling apparatus

Structure of driving unit in a drum type washing machine including a tub mounted inside of a cabinet, a drum mounted inside of the tub, a shaft connected to the drum mounted inside of the tub for transmission of a driving force from a motor to the drum, a front bearing and a rear bearing mounted on an outer circumference of the shaft at opposite end portions thereof respectively, a bearing housing built in a central portion of a rear wall of the tub for supporting the front bearing, a rotor composing the motor together with the rotor, and coupled to the rear end portion of the shaft, a stator fixed to the tub rear wall inward of the rotor to compose the motor together with the rotor, a connector serration coupled to the outer circumference of the shaft in front of the rear bearing and fixed to the rotor, for transmission of a rotating power from the rotor to the shaft, and a bearing bracket fixed to the rear wall of the tub to cover an outside of the rotor and support the rear bearing, thereby reducing noise, repair and power loss, by improving a structure of a driving unit, improving a product reliability, by improving a washing capability, and improving a productivity by improving workability in fabrication of components of the driving unit.
