Abstract

A coin-operated washing/drying machine including a cabinet and a coin box assembly disposed within the cabinet. A supporting structure is fixedly disposed within the cabinet. At least a bottom surface of the coin box assembly is fixedly connected with the supporting structure by a fastener. The fastener passes through from the interior of the coin box assembly and is fixedly connected with the supporting structure. The supporting structure is disposed within the cabinet; the bottom surface of the coin box assembly is fixedly connected with the supporting structure; the fasteners such as screws are thus invisible from an overall appearance. Since the coin box assembly is fixed to the supporting structure by the bottom surface to cause such a fixing structure to be hidden in the bottom surface of the coin box assembly, thereby achieving a good anti-theft effect.

First claim

What is claimed is:
