DRUM-TYPE WASHING MACHINE
Document Type and Number:
Japanese Patent JP3840734
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To eliminate bad conditions where water is leaked because of the deterioration of adhesion between an oil seal and an outer tank due to long time use, a packing member is worn because the core of position of a rotary drum is deviated to be in contact with the packing member, a part of the outer tank is deformed by the load receiving from a bearing case and an abnormal sound is generated.
SOLUTION: A bearing 19 pivoting the rotary shaft 4 of the rotary drum 1 is sealed airtightly by the oil seal 20 housing a bearing case 21, the inner peripheral part of this case 21 is fixed to an outer tank reinforcing plate 23 nearly in the shape of a doughnut fixed to the nearly center part of the outer tank 3 and an outer peripheral part is house-fixed in/to a recessed part arranged in the outer tank 3 to improve adhesion to prevent water leakage, to prevent the deviation of the core of the rotary drum and to prevent the generation of the abnormal sound.
