A safety device for a dishwasher for canteens.

摘要

A safety device for a dishwasher for canteens comprising a washing tank (6) and a protective cover (8) disposed above the tank (6) and adapted to rest thereon or be raised therefrom, the cover being moved vertically and balanced by a spring system (14) provided with a spring (15), a rigid rod (16) and a tie rod (17) jointed together and connected with a bracket (22). The spring (15) is supported by a vertical rod (21) supported by a bracket (22) and the hook (20) of this rod is connected with a spring (40) that tends to move a further rod (28), also connected with the rod (21), into the position in which it locks together the tank (6) and the protective cover (8). As long as the spring balance system (14) functions correctly it permits the cover (8) to be raised from and lowered onto the tank (6), preventing any bond therebetween, but if this system should break down or function incorrectly the rod (28) produces a bond between the tank (6) and the cover (8) when the latter is raised, thus preventing the cover from dropping undesirably and endangering the users of the machine. <IMAGE>
