Disclosed is a clothes dryer including a bearing capable of stably supporting an up and down movement of a drum caused by an unbalanced load inside a drum upon the rotation of the drum, and a method for manufacturing the same. The clothes dryer includes a cabinet provided with a rear plate, a drum rotatably installed inside the cabinet, a shaft configured to transmit a rotational force to the drum, a bearing unit configured to support the shaft and placed between the rear plate and the shaft, and a bearing hole placed on the rear plate and to which the bearing unit is coupled, and the bearing unit includes a ball bearing provided with an inner ring and an outer ring, a bearing housing configured to support the outer ring and inserted into the bearing hole and a bearing bracket coupled to the bearing housing.

A clothes dryer having a control circuit including a speed sensor, wherein the control circuit can sense movement of a portion of a drum assembly. The control circuit uses sensed speed information to control the motor, the heater, or other portion of the clothes dryer. While conventional components can provide a simple speed-triggered on-off switch for the motor or the heater, the present speed sensor approach can provide additional functions by discriminating between varying speeds. The speed sensor can also provide improved accommodation of a broken or slipping drive belt or other drive system problems by sensing the speed of a portion of the drum assembly rather than the motor speed. The speed sensor can replace the functions of multiple conventional components, simplifying the construction and reducing cost. The speed sensor can incorporate a solid state component which has lower cost and improved reliability over standard approaches.

A washing machine with a drying function can include a tub, a drum inside the tub and including: a cylindrical body having a rear end opening, and a drum back coupled to the cylindrical body to be over the rear end opening and including: a plurality of recess portions, a plurality of openings between adjacent recess portions and a plurality of porous plates coupled to the plurality of openings, a motor to provide a rotational force to the drum, a flange shaft between the drum and the motor to transmit the rotational force of the motor to the drum and including: a hub, and a plurality of flange portions extending radially from the hub, a drying duct configured to supply heated air into the tub, and an exhaust duct configured to return the heated air from the tub through the plurality of porous plates to the drying duct.

Dryer appliances, including methods of operation, are provided herein. The dryer appliance may include a cabinet, a drum, a ventilation assembly, an air handler, and a controller. The drum may be rotatably mounted within the cabinet. The drum may define a drying chamber. A ventilation assembly may be attached to the drying chamber. The ventilation assembly may include a conduit defining an exhaust passage in fluid communication with the drying chamber. The conduit may extend from an inlet at the drying chamber to an outlet defined through the cabinet. The air handler may be attached to the conduit in fluid communication with the drying chamber to draw air through the exhaust passage. The controller may be in operable communication with the air handler and the drum, and may be configured to initiate a dry cycle.
