Warewashing machine with drain water tempering system

A warewashing system for dishware with a drain water tempering system, comprising:

• a warewashing machine having a housing defining an internal volume and a hot water tank including a drain, the hot water tank being adjacent the internal volume;
• a drain water fitting having a top end, a bottom end, and a body extending therebetween that defines an interior chamber, a drain water inlet port in fluid communication with the drain of the hot water tank, a drain water outlet port, and a cool water inlet port;
• and
• a drain tempering valve coupled with the cool water inlet port and movable between a closed position in which the drain water tempering valve blocks a fluid flow path into the interior chamber and an open position in which the drain tempering valve opens the fluid flow path, the drain tempering valve including a thermostatic sensor operative about a set point temperature to control the drain tempering valve to the closed position when the thermostatic sensor senses a temperature below the set point and to control the drain tempering valve to the open position when the thermostatic sensor senses a temperature above the set point;
• wherein a longitudinal center axis of the cool water inlet port is disposed between the bottom end of the drain water fitting and a longitudinal center axis of the drain water outlet port.

A drain water tempering system for use with a warewashing machine having a housing defining an internal volume, a hot water tank, and an agitation unit, the drain water tempering system comprising:

• a drain water fitting having a body defining an interior chamber, a drain water inlet port in fluid communication with a drain of the hot water tank, a drain water outlet port, and a cool water inlet port;
• and
• a drain tempering valve coupled with the cool water inlet port and movable between a closed position in which the drain water tempering valve blocks a fluid flow path into the interior chamber and an open position in which the drain tempering valve opens the fluid flow path, the drain tempering valve including a thermostatic sensor operative about a set point temperature to control the drain tempering valve to the closed position when the thermostatic sensor senses a temperature below the set point and to control the drain tempering valve to the open position when the thermostatic sensor senses a temperature above the set point;
• wherein the interior chamber of the drain water fitting defines a top volume portion and a bottom volume portion, the bottom volume portion being disposed below a threshold at which the drain water outlet port intersects the interior chamber of the body, and at least a portion of the thermostatic sensor of the drain tempering valve is disposed within the bottom volume portion of the interior chamber.
