PARTS WASHER WITH IMPROVED TEMPERATURE AND PUMP CONTROL

摘要

A parts washer (10) including a receptacle (12) positioned on a reservoir fo r cleaning liquid having a drain opening (36) and a module (40) which engages a portion of the reservoir in the cleaning liquid for adjusting the temperatur e of the cleaning liquid and circulating the cleaning liquid into the receptac le (12). The module includes a heating element (74), a sensor (75) and pump (78 ). An enclosure (82) houses a temperature controller (100) which displays the temperature of the cleaning liquid and low level condition. A bridge (114) thermally links the heating element to the sensor so that the sensor normall y generates a signal representative of the temperature of the cleaning fluid unless the level of the cleaning fluid is disposed below the sensor.
