Patent ID: 6874512

Claim:
A parts washer for washing mechanical parts, said parts washer comprising, in combination, a parts receiving receptacle positionable on a reservoir for cleaning liquid, a drain opening formed in a part of said receptacle and a module engageable with a portion of the reservoir and the cleaning liquid for adjusting a temperature of the cleaning liquid and circulating the cleaning liquid into the parts receiving receptacle; the module including a heating element, a sensor assembly and a pump assembly including a pump and a motor for driving the pump, each of the heating element, sensor assembly and pump assembly are connected to and supported by a bracket, said bracket extending and depending from an enclosure housing a programmable temperature controller for receiving sensor assembly signals and generating heater element signals; the sensor assembly contiguous with the temperature controller such that the temperature controller displays the temperature of the cleaning liquid and a low liquid level condition; and a bridge thermally linking the heating element to a thermowell of the sensor assembly in which is disposed a thermocouple such that the sensor assembly normally generates a signal representing the temperature of cleaning liquid unless a level of the cleaning liquid is disposed below the sensor assembly.
