  • Publication number: 20090224637
    Abstract: A trim kit type door assembly for an electronic product is disclosed. In the door assembly including door plates and left and right side caps coupled to both sides of the door plates, an opening/closing door handle is integrally formed with one of the left and right side caps, achieving a reduction in manufacturing costs. Also, when the door handle of the side cap takes the form of a recessed portion integrally defined in the side cap so as not to protrude outward from the side cap, the resulting door assembly achieves an exterior appearance satisfying the aesthetic demands of consumers.

  • Publication number: 20090151193
    Abstract: Disclosed is a cloth treating apparatus, which supplies hot air to a accommodating space receiving clothes to dry the clothes. The cloth treating apparatus includes a cabinet including a accommodating space to receive clothes, and an electric component chamber, in which a moisture supply device to spray steam to the accommodating space and a air supply device to supply hot air are installed; and a condensed water treating unit to treat condensed water, generated by condensing the steam sprayed to the accommodating space or the hot air supplied from the air supply device. Therefore, the cloth treating apparatus treats the condensed water generated in the accommodating space, and thus prevents the generation of substances harmful to the human body, such as mold, in the accommodating space.

  • Patent number: 6875001
    Abstract: A reciprocating compressor, wherein a flange unit connected to the mover constituting the reciprocating motor is installed on the piston constituting the compressing unit, the distance between the piston flange unit and the front frame of the frame unit is shorter than that of the between the piston flange unit and the reciprocating motor. In the process of being transmitted the linear reciprocal movement driving force of the reciprocating motor and compressing the gas in the compressing unit, the stability of the compressor is raised by preventing the components moving together with the mover of reciprocating motor from impacting with other components by the displacement generated by compression force applying the piston constituting the compressing unit. Also, the size of compressor can be scaled down by compactly constituting the components.
