JPH06220898A - Water-tight pan for washing machine - Google Patents

Abstract

PURPOSE:To prevent generation of noise since vibration from a washing machine is absorbed and ensure a high workability and a water-tightness. CONSTITUTION:Convex stepped parts 4 bulged inward is formed at a peripheral wall part 2 in the vicinity of four corner parts of a water-tight pan body 3 formed in a receiving pan-like shape by a bottom plate part 1 and the peripheral wall part 2, and vertically piercing throughholes 7 are formed respectively in the stepped parts 4, corresponding to legs of a washing machine. Meanwhile, convex rising pieces made of elastic materials are projected from an attaching plate 9 secured to a floor surface 8, at positions corresponding to the through- holes 7. These convex rising pieces 10 are fitted respectively in the through-holes 7 so that the water-tight pan body 3 is removably superposed and fixed to the attaching plate 9. The legs of the washing machine is set on the rising pieces 10 made of elastic materials, and accordingly, vibration is absorbed. Further, the plate 9 is secured to the floor surface 8 while the water-tightness is ensured by the upper side water-tight pan body 3.
