초록 ▼

A parts washer including a receptacle positioned on a reservoir for cleaning liquid having a drain opening and a module which engages a portion of the reservoir in the cleaning liquid for adjusting the temperature of the cleaning liquid and circulating the cleaning liquid into the receptacle. The module includes a heating element, a sensor and pump. An enclosure houses a temperature controller which displays the temperature of the cleaning liquid and a low liquid level condition. A bridge thermally links the heating element to the sensor so that the sensor normally generates a signal representative of the temperature of the cleaning fluid unless the level of the cleaning fluid is disposed below the sensor.

대표청구항 ▼

What is claimed is: 1. A sensor assembly for detecting a temperature and low liquid level condition of a cleaning liquid in combination with a parts washer, comprising: the parts washer including a reservoir for the cleaning fluid, a receptacle disposed above the reservoir, a drain opening defined in a part of the receptacle for fluid communication between the receptacle and the reservoir and a module; a heating element extending from the module and substantially immersed in the cleaning fluid; a thermowell immersed in the cleaning liquid; a thermocouple disposed with the thermowell and operatively coupled to a temperature controller of the module; and a bridge connected at a first-end to the thermowell and at a second end to the heating element such that the thermocouple detects the temperature of the cleaning fluid in an operating condition and the bridge conducts heat directly from the heating element to the thermowell and the thermocouple disposed therein when the cleaning liquid is in a low liquid level condition. 2. The sensor assembly and parts washer combination as defined in claim 1, wherein the bridge is constructed from a thermally conductive material. 3. The sensor assembly and parts washer combination as defined in claim 1, wherein the first end of the bridge engages the thermowell without encircling and the second end of the bridge engages the heating element without encircling. 4. The sensor assembly and parts washer combination as defined in claim 1, wherein the first end of the bridge encircles the thermowell and engages the thermowell with an interference fit and the second end of the bridge is contiguous with the heating element. 5. A sensor assembly for detecting a temperature and low liquid level condition of a cleaning liquid in combination with a parts washer, comprising: the parts washer including a reservoir for the cleaning fluid, a receptacle disposed above the reservoir, a drain opening defined in a part of the receptacle for fluid communication between the receptacle and the reservoir and a module; a heating element extending from the module and substantially immersed in the cleaning fluid; a thermowell immersed in the cleaning liquid; a thermocouple disposed with the thermowell and operatively coupled to a temperature controller of the module; and the thermowell disposed closely proximate the heating element such that the thermocouple detects the temperature of the cleaning fluid in an operating condition and when the cleaning liquid is in a low-liquid level condition the thermocouple detects the temperature of the heating element rather than the temperature of the cleaning liquid.
