(54) | CASE FOR DISHWASHER-USE WASHING BALLS |
(57) The present invention relates to a washing ball case for a dishwasher, used to wash
dishes by washing balls of a ceramic material and washing water without using any
detergents and, more particularly, to a washing ball case for a dishwasher, wherein
a case body (100) is formed by thermally bonding a top plate (10) and a bottom plate
(20) and has through holes (120) formed in an outer side portion thereof so as to
completely drain the washing water at the time of washing dishes such that the washing
balls can be maintained in a dried state through the complete draining of the washing
water and the washing efficiency of the washing balls can be maximized in next dish-washing,
and through holes (120) and reference grooves (130) are provided to the outer portions
of the top plate (10) and the bottom plate (20) such that, at the time of the thermal
bonding, the top plate (10) and the bottom plate (20) can be bonded to each other
at uniform positions in a fixed state without movement by the through holes (120)
and the reference grooves (130) so as to prevent the conventional bonding defects.
