Abstract

A humidifier assembly for bakery proof boxes for inservice removal of water and water-borne impurities has a water receptacle with a nonstick coating which includes an interior bottom with a raised section and a contiguous lowered sump. Surrounding sidewalls contain water which is heated. Water from a water supply passes through a solenoid valve and into a nozzle injecting water against the raised floor. The water contacts a near sidewall, creating turbulence and a scrubbing action and spreads over the entire raised floor. Heating elements are provided to heat the raised bottom section of the receptacle without heating the sump and water in the sump. Such elements are cast in the bottom section of the receptacle. Water and impurities are removed from the sump through an outlet conduit which is connected to a venturi. The venturi is connected to a drain line and to the water supply through a flush solenoid valve. A siphon breaker is provided. A pressure switch which is connected to a bell submerged in the sump activates the fill solenoid valve. Under the control of a timer, or manually, as desired, the flush solenoid valve is periodically actuated to create a suction in the venturi and remove water and water-borne particles. Water flows also through a check valve and into the nozzle to wash particles from the wall of the receptacle and the raised floor.
