Appl. No.:

10/973510

International Classification:

H01H 50/54
G08B 21/00

US Classification:

340652, 361245

Abstract:

An alarm device that connects to a circuit using two wires and is actuated when a switch changes the status of the circuit from a normally closed circuit condition to open circuit condition. The alarm device includes a PC board with an electronic buzzer, an electronic signal transmitter and/or a visual indicator, such as a flashing LED, all of which may be enclosed within a case. The circuitry of the alarm device is non-polarized, thereby allowing the two wires to be connected to either terminal connection point in the circuit.

Abstract:

A condensate overflow safety switch that can be used with an air handling system is disclosed. The air-cooling system includes a drain pan for collecting liquid condensed on the evaporator coils. The drain pan is fluidwise connected to the safety switch that is in turn electrically connected to a circuit of the air handling system. To reduce the probability of an overflow from the drain pan arising from an occlusion to water liquid draining from the drain pan, an annular float is mounted about a tube in which is sealed a reed switch electrically connected to a circuit of the air handling system or to an alarm circuit. The float containing an annular magnet ascends or descends based on the level of water liquid within the structure. If a predetermined level of condensate liquid within the safety switch tubular structure exists, the float will have ascended such that the magnetic field of the annular magnet will cause a reed switch to open in the case of the air handling circuit, or to close in the case of an alarm circuit. Upon removal of the drainage occlusion, the water liquid level within the tubular structure will decrease below the predetermined level thereby causing the float to descend and the reed switch contacts to engage or to disengage, thereby rendering the circuit of the air handling system operative or alarm circuit inoperative, respectively. The disclosed condensate safety switch with its tubular structure, either T-shaped or L-shaped; is compact and easy to install, can be installed at any slope from horizontal to vertical and, by virtue of its sealed electrical components, is of heightened reliability in warning of drain line occlusions and/or preventing drain pan overflows.

International Classification:

F25D021/00
F25D021/14

US Classification:

062150000, 062285000

Abstract:

A safety switch prevents overflow of condensate that collects in the drain pan of an air-cooling system. The overflow safety switch attaches to the condensate drainage system and is electrically connected to a circuit of the air-cooling system, a power circuit, a control circuit and/or an alarm circuit. The switch includes a tube that extends within the condensate drain pan or any other water conducting point in the condensate drainage system. A reed switch is sealed within the tube and a float containing a magnet is moveably supported on the exterior of the tube. The float ascends or descends in response to the level of the liquid condensate within the drain pan. As the float moves relative to the tube, the magnet causes the reed switch to open, thereby interrupting operation of the air-cooling system and/or actuating the alarm circuit.

US Classification:

220009200

Abstract:

A disposable trash container has a lining made of plastic or other material forming a bottom and sides, and an expandable spring loaded frame structure connecting between a base at the bottom of the lining and a top hoop near a closable top opening of the lining. One or more clasps hold the lining and frame structure collapsed flat near the base in a low profile state for packaging. When ready for use, the clasp(s) is operated to release the spring loaded frame structure, thereby causing the trash container to open as the frame structure expands and the top hoop moves upwardly and away from the base. The top opening of the lining may be provided with a drawstring or other means to close the trash container prior to disposal.

Abstract:

A PC board containing electronic components of a normally closed switch is enclosed in a case and connects to a circuit using two wires. Electrically conductive sensor-probe pins extend from the PC board and are positioned for detecting liquids at various levels within drains, drain pans, tanks, reservoirs and pipes of various dimensions. An optional remote probe, having a pair of electrically conductive sensor probe pins, connects to the PC board and is adapted for positioning at a location that is separated from the enclosed case, such as in an auxiliary drain pan of an HVAC system. The normally closed switch is actuated to an open state upon a rising liquid level contacting the tips of the sensor probe pins. Actuation of the switch to the open state changes the status of the circuit from a normally closed circuit condition to an open circuit condition, thereby interrupting operation of a system (e.g. HVAC) on the circuit. Actuation to the open circuit condition may be visibly indicated by an illuminated LED on the exterior of the case. In one embodiment, the circuitry of the liquid level sensor switch is non-polarized, thereby allowing the two wires to be connected to either terminal connection point in the circuit.
