Embodiment Construction

[0028] Although the present invention can allow various forms of embodiments, the currently preferred embodiments are shown in the accompanying drawings and will be described below. It should be understood that the present disclosure should be regarded as an example of the present invention, and it is not intended to describe the present invention. Limited to the specific examples described.

[0029] First a brief reference image 3 , Schematically shows the separation liquid level sensor 10 embodying the principle of the present invention. The sensor 10 includes a detector 12 formed of elongated elements that can be manufactured in various different materials and in various different shapes.

[0030] The sensor 10 is installed in the system to detect the presence or absence of liquid in contact with the detector 12. In an exemplary application for use in an ice maker (not shown), the sensor 10 is positioned to detect the presence or absence of water (and thus its level) in a wate...

Abstract

A level sensor for determining the presence or absence of a liquid in contact with the sensor includes an elongate probe, a transducer operably connected to the probe and configured to produce compressional waves in the probe, and circuitry for detecting acoustic energy emitted into the liquid when liquid is in contact with the probe. A mount for the releasably holding the sensor includes a base have a receiving region formed in part by a plurality of flexible securing fingers. The fingers have locking projections extending therefrom. A contact is mounted to the base and extends into the receiving region. A cartridge supports the level sensor and is received in the receiving region. The cartridge includes a circumferential recess for receiving the securing fingers. When the level sensor is positioned in the cartridge and the cartridge is inserted into the base, the level sensor is operably connected to the contact and the cartridge is resiliently secured in the base.

Description

[0001] Cross-reference relevant application data [0002] This application claims priority to the provisional U.S. Patent Application Serial No. 60 / 880,822 filed on January 17, 2007 entitled "Separated Liquid Level Sensor". Technical field [0003] The invention relates to a liquid level sensor and a base. More specifically, the present invention relates to a liquid level sensor that is insensitive to mineral deposits on the surface of the sensor and a base for the sensor. Background technique [0004] One common type of liquid level sensor is the capacitive sensor. For example, such sensors are used in automatic machines such as automatic ice making machines. In a typical capacitive sensor, a rod-shaped metal electrode is installed vertically above the water reservoir. Each machine cycle, the reservoir is filled and emptied to reduce the accumulation of dissolved solids that can cause the ice to have a cloud-like appearance. [0005] A small high-frequency voltage is applied to t...
