Provided is a composite thermal insulation sheet including an aerogel and a method for manufacturing the same. The methods yield an ultra-thin aerogel composite sheet having characteristics of low dust, high strength and high thermal insulation, thereby having an increased applicability thereof to an electronic device.

Composite thermal insulation sheet including aerogel

An enamel coating including a phosphate-based ingredient is provided on an inner surface of a cooking chamber and the inner surface of the cooking chamber is cleaned using high-temperature cleaning water. Therefore, the cleaning of the cooking chamber can be performed more efficiently.

Cooker

A cooking apparatus includes a case in which a cooking chamber for cooking food is provided, a heating source provided in the case, a fan configured to circulate air in the cooking chamber; and a plasma discharger provided in the case and configured to generate plasma in order to remove residue from a surface of the case.

Cooking apparatus with plasma cleaning

A lighting apparatus which uses microwave energy which includes a microwave generator disposed inside a casing for generating microwave energy, a waveguide for transmitting the microwave energy, a resonator for covering an outlet of the waveguide, a bulb placed inside a resonator for generating light by the microwave energy transmitted through the waveguide, a conduction block in contact with the microwave generator for receiving heat generated in the microwave generating process, a heat transfer unit connected between the conduction block and the casing for transmitting heat from the conduction block to the casing and a radiating unit installed at the end of the heat transfer unit for radiating heat transmitted from the conduction block to the casing or outside of the casing.

Lighting apparatus using microwave

An electrodeless lamp is disclosed. The electrodeless lamp according to the present invention is characterized in that SnI is used as a major component filled into a bulb as a filler, and the filler is excited by applying a microwave or high frequency to the bulb for thereby generating a visual ray for thereby obtaining a certain color temperature proper as a light source and implementing a faster light emission start-up at a lower cost without an additive.

Electrodeless lamp using SnI2

A resonator for use in microwave lighting apparatus includes a mesh portion formed in a cylindrical shape with one side opened, at least one portion of which prevents microwave transmitted through a waveguide from leaking and light radiated from a light bulb is transmitted outwardly, the mesh portion being formed integral without a joint. Since the portion of the mesh structure is integrally formed as one body without a joint rather than being welded to be coupled, the microwave is prevented from leaking. In addition, since the holes of the mesh portion are uniformly formed without any clogged portion, the light transmittance area is enlarged, improving the light efficiency of the lighting apparatus.

Resonator for microwave lighting apparatus and manufacturing method thereof

A food weight sensing device of a microwave oven using a variable capacitor of which the capacitance is varied in accordance with pressure applied thereto. The device comprises of first and second electrodes placed on a side portion of a lower surface of a cooking chamber, the side portion being included in a rotating trail of a roller applied with part of the food weight, each of the electrodes comprising a metal plate spring. A spacer is interposed between the first and second electrodes to space out the electrodes from each other at a predetermined interval. A rubber plate engages with the first electrode for transmitting the food weight to the first electrode. The first electrode comprises a center circular push part, an outer flange part and at least two arcuate ribs connecting the center circular push part to the outer flange part. The spacer is made of a metal so as to electrically connect the first electrode to a printed circuit board. This device precisely and easily senses the food weight by sensing a varied capacitance of the variable capacitor.
