Low temperature warewasher with temperature drain feature

摘要

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.

主权项

1. A warewashing apparatus, comprising:
a common wash and rinse tank for storing wash water and rinse water, the tank having a drain outlet; a water supply conduit communicated with the tank; a fill valve communicated with the water supply conduit, the fill valve being movable between a water supply open position and a water supply closed position; a drain valve communicated with the drain outlet, the drain valve being movable between a drain open position and a drain closed position; a temperature sensor operably associated with the tank and configured to sense a water temperature within the tank; a set point input configured so that an operator can adjust a set point temperature for a minimum tank water temperature for a wash cycle; and a controller operably associated with the drain valve, the fill valve, the temperature sensor and the set point input, the controller being configured to automatically control a wash cycle and then a rinse cycle in the common wash and rinse tank upon receiving a start wash cycle signal, the controller being configured to initiate a low temperature drain and refill cycle of the tank prior to starting the wash cycle if the tank water temperature is below the set point temperature.
