Combinational weighing machine with washing device

A combinational weighing machine has weigh hoppers for weighing articles, a dispersion feeder for dispersing articles to be weighed, supply troughs for supplying articles from the dispersion feeder to the weigh hoppers and a control unit for controlling overall operations of the machine inclusive of combining weight values outputted from the weigh hoppers and discharging articles from selected ones of these weigh hoppers. The weighing machine is placed inside a washing device which forms a closed chamber inside and covers the weighing machine from all its four sides as well as from above. Nozzles for emitting warm water and a cleaning liquid are provided inside this chamber such that the liquids are prevented from splashing the work areas around the machine. The washing device may be lifted and kept away from the weighing machine during a normal mode of operation of the latter.
