Problems solved by technology

[0007] In addition, complex shapes can lead to product distortion and other defects that typically occur during the manufacture of drive unit components, including the tub 10, bearing housing 30, and base 40, thereby causing size and shape mismatches between the components
Large degrees of bending of complex shapes cause correspondingly large deformations, which lead to high frequency occurrence of manufacturing defects of drive unit components

Abstract

A drum type washing machine is provided having a simplified drive unit support structure design and improved vibration dispersion characteristics. The washing machine includes a tub, a drum disposed inside the tub, a shaft coupled to the drum, a bearing supporting the shaft, a bearing housing supporting the bearing, and a base secured to the tub. The bearing housing has a rear end protruding from a rear wall of the tub, and the tub has an extension facing an outer peripheral surface of the rear end of the bearing housing.

Description

technical field [0001] The present invention relates to a drum type washing machine, and more particularly, to a drum type washing machine including a structurally improved driving unit. Background technique [0002] Generally, a drum type washing machine is provided with a motor pulley and a drum pulley under a tub in which a drum is disposed so that driving force of the motor is transmitted to the drum through a belt connecting the motor pulley and the drum pulley. [0003] As such, the conventional washing machine suffers from energy loss because the driving force of the motor is transmitted to the drum through the belt, and generates a lot of noise during energy and power transmission. [0004] figure 1 It is a sectional view of a part of a drive unit of a conventional front-loading washing machine. [0005] Such as figure 1 As shown, the conventional drum type washing machine includes a tub 10 , a shaft 20 and a base 40 . A tub 10 with a roller (not shown) is locate...
