H05B 102

US Classification:

219505, 219212, 219497, 219548, 219552

Abstract:

A thermo-sensitive heater and heater driving circuit are disclosed. The thermo-sensitive heater comprises a cord-shaped nylon thermistor that surrounds a heating element, such that the thermistor detects the temperature of the heating element and controls the driving current for a heating coil. Also, the present invention includes electromagnetic shielding material, which is formed by winding an electric conductor around the outer surface of the nylon thermistor, or formed as a wire mesh. This shielding material is advantageous for discharging the electric field radiated from inside of the heater to an external electric field, thus safely eliminating harmful electric fields. Also, the present invention further provides a driving circuit for safely driving the heater, which includes a temperature controller or an overheating prevention circuit.

International Classification:

H05B 3/10

US Classification:

219548

Abstract:

The present invention relates to a magnetic field-blocking panel heater. The magnetic field-blocking panel heater includes a panel heating element comprising a heat generating electrical conductor enclosed in an electrical insulator and first electrodes for transferring current to the electrical conductor. A magnetic field-blocking material surrounds the panel heating element.

Inventors:

Myoung Jun Lee - Cerritos CA

International Classification:

A45D 2010

US Classification:

392385

Abstract:

An electric field shielding apparatus used with an electrical device comprises a housing body at least partially surrounding the electrical device; and a conductive shield medium arranged with the shape of the housing body to at least partially surround the electrical device to substantially reflect electric field generated from the electrical device. The conductive shield medium is a thin conductive layer coated on interior surface of the housing body. Alternatively, the conductive shield medium is a conductive mesh placed against interior surface of the housing body. In addition, the conductive shield medium may be integrally mixed with the housing body to make the housing body substantially electrically conductive. In other words, the conductive shield medium may be in a powder form which is mixed with plastic power, the mixture of which is then heated and poured into an injection mold to form a housing body of an electric device. To effectively block or absorb the electric field generated from a device, the conductive shield medium is preferably grounded by being connected to a ground prong of a power outlet.

International Classification:

H05B 100

US Classification:

219212

Abstract:

An electric blanket using an AC to DC converter circuit either alone or in combination with a shield mesh that surrounds the heating wire to substantially reduce the electromagnetic field produced by the heating wire. The electric blanket has a heating element having a conductive wire and a shielding component, in which the conductive wire is placed between the shielding component to substantially encase the conductive wire. To discharge any build up of electrical charges, the shielding component is coupled to the ground. The electric blanket also has a control device for use with the alternating electrical current. The control device has a temperature control circuit that controls the current flow pursuant to the temperature setting. A converter device used in the electric blanket is electrically connected to the outputs of the control device. The converter device includes a rectifier circuit connected to the control device and has output terminals to generate rectified current from the alternating electrical current; and a filter circuit connected across the output terminals of the rectifier circuit to provide direct electrical current to the wire of the heating element.
