Benefits of technology

[0013] An object of the present invention is to provide a drum washing machine which includes a balance weight mounting structure capable of reducing vibration generated at a tub of the drum washing machine, thereby being capable of preventing the tub from being damaged at regions where bolts are fastened, during operation of the drum washing machine, while preventing the front wall of the tub from being damaged due to contact between the tub and a drum arranged in the tub.

Problems solved by technology

As a result, the drum 4 cannot be smoothly rotated during operation of the drum washing machine.
In this case, the tub cover 3a may be damaged because the tub cover 3a is made of a plastic material.

first embodiment

[0046]FIG. 4 illustrates a balance weight mounting structure for mounting balance weights in a drum washing machine in accordance with the present invention. In this case, the drum washing machine includes a cabinet 100, which forms an outer appearance of the drum washing machine, a tub 30 arranged in the cabinet 100 to contain washing water, and a drum 40 rotatably arranged in the tub 30 to carry out a laundry washing function in accordance with rotation of a motor 80 mounted to a rear wall of the tub 30.

[0047] Balance weights 50 are mounted to a front wall of the tub 30 such that the balance weights 50 are symmetrical with respect to a first center line I-I extending vertically through the center c of the front wall of the tub 30 along the front wall of the tub 30. The balance weights 50 are also symmetrical with respect to a second center line II-II extending through the center c of the front wall of the tub 30 in perpendicular to the first center line I-I along the front wall of...

second embodiment

[0049] Meanwhile, FIG. 5 illustrates a balance weight mounting structure for mounting balance weights in a drum washing machine in accordance with the present invention. In this case, balance weights 50 are mounted to the front wall of the tub 30 such that the balance weights 50 are symmetrical with respect to a third center line III-III extending diagonally through the center c of the front wall of the tub 30 along the front wall of the tub 30. The balance weights 50 are also symmetrical with respect to a fourth center line IV-IV extending through the center c of the front wall of the tub 30 in perpendicular to the third center line III-III along the front wall of the tub 30.

[0050] In both the first and second embodiments illustrated in FIGS. 4 and 5, the weight of each balance weight 50 is determined, taking into consideration the weight of the motor 80 mounted to the rear wall of the tub 30. In either embodiment, it is preferred that the total weight of the balance weights 50 be ...

third embodiment

[0056] As shown in FIG. 6, the drum washing machine applied to the present invention includes a cabinet (not shown), which forms an outer appearance of the drum washing machine, a tub 30 arranged in the cabinet to contain washing water, and a drum 40 rotatably arranged in the tub 30 to carry out a laundry washing function in accordance with rotation of a motor (not shown) mounted to a rear wall of the tub 30.

[0057] A suction duct 10 adapted to suck air into the drum 40 and an exhaust duct 20 adapted to exhaust air from the drum 40 are mounted to the tub 30. An air inlet 31 is formed at the tub 30 in order to communicate the tub 30 with the suction duct 10. Balance weights 50 are mounted to a front wall of the tub 30 in such a manner that the front wall of the tub 30 is balanced in weight between positions opposing to each other with respect to the center of the front wall of the tub 30.

[0058] As described above, this drum washing includes the suction duct 10 and exhaust duct 20 for...

Abstract

A drum washing machine including an improved balance weight mounting structure is disclosed. The drum washing machine includes a cabinet which forms an outer appearance of the drum washing machine, a tub disposed in the cabinet such that the tub is balanced in weight between positions opposing to each other on a front wall of the tub with respect to a center of the front wall of the tub, and a drum rotatably disposed in the tub to perform a washing function in accordance with a rotation of a motor attached to a rear wall of the tub. Balance weights are mounted to the front wall of the tub to cause the tub to be balanced in weight between positions opposing to each other on the front wall of the tub with respect to the center of the front wall of the tub.

Description

[0001] This application claims the benefit of the Korean Patent Application No. 20074-39601, filed on Jun. 1, 2004, which is hereby incorporated by reference as if fully set forth herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a drum washing machine, and more particularly, to a drum washing machine including a tub, and a drum rotatably mounted in the tub, wherein the mounting structure for balance weights mounted to a front wall of the tube for weight balance, taking into consideration the weight of a motor mounted to a rear wall of the tub, is improved. [0004] 2. Discussion of the Related Art [0005] Generally, drum washing machines wash laundry, utilizing friction generated between the laundry and a drum, which is horizontally arranged, and is rotated by a drive force of a motor, under the condition in which detergent and washing water are placed into the drum, together with the laundry. Such a drum washing machine has a...
