Disclosed is a battery including a cathode and an anode wound to face each other with a separator interposed therebetween. Both surfaces of a cathode collector are provided with cathode active-material coating layers so as not to provide a cathode uncoated part at a winding beginning portion of the cathode. The cathode uncoated part for installation of a cathode lead is provided only at a winding ending portion of the cathode. An insulator tape is attached to the boundary of the cathode active-material coating layer facing the anode at the winding ending portion of the cathode. Providing the insulator tape to the boundary of the cathode active-material coating layer at a position where a non-coating part not containing the cathode active-material coating layer and an anode active-material coating layer face each other achieves enhanced electrical insulation capability and consequential safety of the battery.

Disclosed is a jelly-roll type electrode assembly (“jelly-roll”) configured by winding a cathode having a cathode active material coated portion formed at at least one side of a cathode current collector and an anode having an anode active material coated portion formed at at least one side of an anode current collector in a state in which the cathode and the anode are opposite to each other via a separator, wherein a cathode tab mounted at an uncoated portion of the cathode so that the cathode tab is inclined upward at a predetermined angle to a longitudinal direction of the cathode and an anode tab mounted at an uncoated portion of the anode so that the anode tab is inclined upward at a predetermined angle to a longitudinal direction of the anode are located so as to be adjacent to each other.

Disclosed herein is an oven that is capable of discharging hot air generated when cooling a door and heat generated in a cooking chamber through the lower end of the door. The oven includes a door having at least two separated air channels. The air channels comprise at least one first air channel to discharge hot air generated when cooling the door through the lower end of the door, and at least one second air channel to introduce air through the lower end of the door such that the door is cooled. In the housing is mounted a circulating fan. Between the circulating fan and the air channels is connected a channel connecting unit. As the circulating fan is rotated, air flows along the second air channel to cool the door. Hot air generated when cooling the door is introduced into the first air channel through the channel connecting unit, and is then discharged out of the oven through the lower end of the door.

A door damper. The door damper includes a rotational shaft rotatably coupled to a door, a rotating resistance unit to generate rotating resistance to the rotational shaft, and a latching device latched to the rotational shaft and the door so as to allow the door and the rotational shaft to rotate together in a predetermined region. The latching device includes a free rotating section enabling free rotation of the door at an initial stage of opening the door, and a latching section enabling the latching device to be latched to the rotational shaft and the door at a final stage of opening the door so as to allow the door and the rotational shaft to rotate together. With the door damper, the door of electronic appliances can be smoothly opened without impact, and can be easily closed.

A cooking apparatus performing cooking with a cooking container disposed at any desired position on a cooking plate, and a heating device thereof. The cooking apparatus includes a cooking plate to receive a cooking container thereon, and at least one working coil disposed under the cooking plate to heat the cooking container, the at least one working coil including a first portion and a second portion having a different winding structure of a conducting wire which forms the working coil so that a winding density of the conducting wire at one of the first portion and the second portion is relatively higher than the other of the first portion and the second portion.

A high voltage transformer includes an E-shaped core having grooves into which electrical parts are inserted, an I-shaped core supporting the E-shaped core, and an insulating element inserted between the E-shaped core and the I-shaped core to insulate the electrical parts. The electrical parts are primarily insulated by the insulating element inserted into the transformer, so that a conventional insulation process may be shortened. Additionally, low-cost insulating papers may be used to insulate the electric parts, so that the manufacturing cost of the transformer may be reduced.

Disclosed herein are a heating device usable with a cooking appliance and a manufacturing method thereof to assure economical formation and arrangement of a working coil. The heating device usable with a cooking appliance includes a working coil formed by spirally winding a conducting wire, and a sheet member arranged to support the working coil and having a supporting plane facing the working coil. Individual windings of the conducting wire, which constitute individual turns of the working coil, are spaced apart from neighboring windings by a predetermined distance. Spaces are defined between the individual neighboring windings of the conducting wire without a structure to guide the working coil.
