Abstract

A method for washing a conveyer belt in a heat treatment apparatus permits washing of the conveyer belt without causing splashing of a washing fluid so as not to cause danger in operation and contaminate the surroundings and can cause deformation of the conveyer belt upon washing so as to vary the surface configuration and positional relationship of the components for making washing effective. The method comprises the steps of defining a washing fluid bath containing a washing fluid, and placing the washing fluid bath in a portion of a traveling path of the conveyer belt, within which at least one of configuration and positional relationship of components of the conveyer belt varies, for dipping the conveyer belt at the portion within the washing fluid bath. Apparatus for carrying out the method includes a washing bath which can be shifted between a first position away from a vertically deflected portion of the conveyor belt and a second position dipping the vertically deflected portion of the conveyor belt in the washing bath. The washing bath is shifted between the first and second positions by a pivotal lever.
