Problems solved by technology

Such sensors, typically located at or near the edge of a removable filter pan, can be problematic as they can become jammed, broken, or otherwise damaged during pan movement
Additionally, touch sensor pads that engage or activate when the filter pan is in place can become dirty, damaged, or incapacitated, and when located in inaccessible areas, are difficult to clean, repair, or replace

Embodiment Construction

[0020] exist figure 1 A capacitive sensor probe according to the present disclosure configured for installation in a fluid environment, such as in the case of a filter disc, is shown in . The sensor probe 100 is configured and constructed to operate over a wide range of temperatures, across a wide range of fluid viscosities from partially solid to low viscosities, and is typically made of "food-safe" materials, as these materials may interact with food Use in exposed cooking environments. In operation, as described in more detail below, the capacitive sensor probe acts as the "plate" of a capacitor, along with a metallic portion of the environment housing the probe 100 (eg, a portion of a metal fryer), and the fluid placed in the environment acts as the capacitor's dielectric.

[0021] Sensor 100 is implemented as a capacitive sensor that senses the capacitance of fluid surrounding the sensor. In an illustrative embodiment, a sensor according to the invention is placed on or...

Abstract

A capacitive sensor and control system is configured to detect the presence (or absence) of a filter pan and of fluid within a filter pan. Configured in a filter pan of a deep fryer, the sensor determines when a level of liquid within the filter pan is at or above the level of the. The sensor is in communication with the control system and the sensor sends a signal to the control system representative of the presence of liquid within the filter pan and at the level of the sensor. The controller receives the signal from the sensor, and allows operation of a fluid management system and its associated plumbing to completely and safely move oil into and out of the filter pan.

Description

technical field [0001] This specification relates to fluid sensors and detection systems, and more particularly to sensors implemented in controlled cooking systems. Background technique [0002] In some known controlled cooking systems, such as deep frying cooking systems, control systems and associated sensors may be used to detect the presence or level of fluid in the system to ensure that the systems operate at the desired times. [0003] Additionally, in some cooking systems, removable filter pans are used to filter and remove debris and / or other impurities from the fluid. However, these removable filter discs require multiple sensors for different purposes. For example, a sensor is used to detect and ensure that the removable filter pan is properly placed in the fryer. Additional fluid sensors are also required to detect the presence of fluid in these pans. [0004] Known systems include a plurality of sensors, each having its own purpose. For example, level sensor...
