Abstract: A tubular frame assembly for a door type warewashing machine includes four tubular legs, and two upper cross-braces and two lower cross-braces. The cross-braces are received through cross-brace receiving openings in the tubular legs, and the cross-braces are bolted together within the legs by nut and bolt assemblies.

Abstract: A dump and fill low temperature chemical sanitizing warewasher includes a wash and rinse tank and a temperature sensor associated with the tank and configured to sense a water temperature within the tank. A controller is connected to the temperature sensor to receive the water temperature sensor. The controller is configured to initiate a low temperature drain and refill cycle prior to starting a wash cycle, if the controller determines that the water temperature is below a set point.

Abstract: A vapor vent for use with an industrial washing machine that increases heat performance of the industrial washing machine by removing vapors from outside two sets of curtain structures rather than in between the curtain structures. The design of the vapor vent is such that vapors and/or steam are extracted from the outer surface of the outer curtain structures proximate the openings of a conveyor type washer without extracting heat from the internal cavity of the housing unit. The vapor vent achieves this by being mounted externally from the vent cowl so as to suction vapors and/or steam that have escaped the outermost curtain, outer curtain structure. This is an improvement upon the old design that withdrew vapors as well as heat from within the machine because the vent is mounted into the vent cowl and has a detrimental effect on the heat performance of the machine.

Abstract: Disclosed is a warewashing assembly comprising a batch-loading warewashing machine and a movable tray or cart capable of holding a rack in a position that departs form the horizontal outside of the warewashing machine for convenient operations; said tray or cart comprising a flat tray of a size complementary to said rack, wherein the flat tray comprises side and rear fences capable of holding the ware rack against horizontal motion and wherein the tray is attached to a support structure in such a way that it is supported at the desired angle .alpha. and can be inserted into the machine when quiescent; wherein the support structure is of a height approximately equal to that of the warewashing machine and comprises means to move horizontally in relation to the warewashing machine.

Abstract: Household and institutional sinks are commonly used in cleaning regimens in which articles are contacted with aqueous cleaning media under conditions of agitation. Such agitation can be provided by directing the aqueous medium contained within the sink to a pump that returns the aqueous medium to the sink under agitating conditions such that the agitation can act to promote soil removal. The aqueous medium can be withdrawn from a waste line installed in a sink drain. The aqueous medium can then pass into a pump which can return the aqueous medium to the sink at a location in the sink causing the aqueous medium to agitate and circulate within the sink bowl. Preferably, valved waste line hardware can be installed in the drain such that when the waste line valve is closed, the aqueous medium is retained in the sink. The pump intake is placed in liquid communication with the aqueous cleaning medium upstream of the valve.
