  • Patent number: 7558457
    Abstract: A combined illumination and ventilation duct is disclosed. The present invention includes at least two optical pipes having air flown inside wherein light proceeds within the at least two optical pipes by being totally reflected and a connector connecting the at least two optical pipes together, the connector having a connecting nipple to be connected to a pipe. An upper part of the duct is embedded in a fake ceiling under a real ceiling and a lower part is exposed under the fake ceiling. Alternatively, the whole combined illumination and ventilation duct is installed to be exposed under the fake ceiling. As air and light pass through the combined illumination and ventilation duct, the light is totally reflected within the optical pipes to illuminate an indoor space and the air is supplied or discharged to ventilate the indoor space.

  • Publication number: 20070049189
    Abstract: A ventilator is provided. The ventilator includes blowers 60 and 70; ducts 62 and 72 that are connected to the blowers 60 and 70 to form a blow path having at least one bent part; and a sound-absorbing material 90 that is provided in the bent part of the blow path of the ducts 62 and 72 to absorb noise within the blow path thereof. Therefore, it is possible to remarkably reduce or prevent flow noise that is propagated to the inside of a room as noise of a flow passing through the ducts 62 and 72 is absorbed by the sound-absorbing material 90.
