Drum type washing machine and drum therefor

Abstract

Disclosed herein is a drum type washing machine. The drum type washing machine comprises front and rear balancers mounted at the front and rear sides of a drum, respectively. Consequently, an eccentric force generated by laundry is complementarily eliminated by the front and rear balancers even when the laundry is eccentrically placed at one side of the drum.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a drum type washing machine, and, more particularly, to a drum type washing machine having balancers mounted at the front and rear surfaces of a drum for eliminating an eccentric force generated by laundry. [0003] 2. Description of the Related Art [0004]FIG. 1 is a sectional view illustrating the interior structure of a conventional drum type washing machine. [0005] As shown in FIG. 1, the conventional drum type washing machine comprises: a cabinet assembly 110 having a base 101 and a door 102; a tub 120 mounted in the cabinet assembly 110; a drum 130 rotatably disposed inside the tub 120; a motor 140 for rotating the drum 130; a spring 150 and a damper 160 for attenuating vibration transmitted to the cabinet assembly 110 from the tub 120; and a balancer 170 for attenuating vibration generated at the drum 130. [0006] The drum 130 has a plurality of holes 104, through which wash water...

AI Technical Summary

Benefits of technology

[0017] Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a drum type washing machine that is capable of effectively eliminating an eccentric force generated by laundry when a drum is rotated.

[0019] In accordance with one aspect of the present invention, the above and other objects can be accomplished by the provision of a drum for drum type washing machines, comprising: a hollow drum body; a drum front mounted in the front of the drum body, the drum front having an opening; a drum back mounted at the rear of the drum body; a hub fixed to the rear surface of the drum back; and front and rear balancers mounted in the front and the rear of the drum body, respectively, for complementarily eliminating an eccentric force generated at the drum body when the drum body is rotated.

[0026] In accordance with yet another aspect of the present invention, there is provided a drum type washing machine comprising: a cabinet assembly forming the outer appearance of the drum type washing machine; a tub mounted in the cabinet assembly in a supported fashion; and a drum rotatably disposed inside the tub, wherein the drum comprises: a hollow drum body; a drum front mounted in the front of the drum body, the drum front having an opening; and a drum back mounted in the rear of the drum body; and front and rear balancers mounted in the front and the rear of the drum body, respectively, for complementarily eliminating an eccentric force generated at the drum body when the drum body is rotated.

[0028] According to the present invention, the front and rear balancers are mounted at the front and rear sides of the drum, respectively, and therefore, the eccentric force generated by the laundry is complementarily eliminated by the front and rear balancers even when the laundry is eccentrically placed at one side of the drum.

Problems solved by technology

As a result, appropriate balancing is not accomplished by the balancer 170.
