  • Publication number: 20060223432
    Abstract: An air-conditioning duct is provided inside a car console box that has an ornamental portion. The duct has an air passage for conducting conditioned air from an air conditioner to the passenger compartment. The air passage is defined by a first wall portion formed by the ornamental portion, a second wall portion opposed to the first wall portion, a third wall portion located between the first and the second wall portions, and a fourth wall portion located between the first and the second wall portions. The fourth wall portion is opposed to the third wall portion. Each wall portion has an inner surface exposed to the interior of the air passage. A pair of boundary lines are defined on the inner surface of the first wall portion at boundaries between the first wall portion and the third and fourth wall portions. A dew condensation suppression portion is provided on the inner surface of the first wall portion between the pair of the boundary lines.

  • Patent number: 7103979
    Abstract: Fanned air generated by a fan to cool a motor is discharged from a housing through fanned air discharge ports toward an opening formed in a base. The fanned air discharged toward the opening is then introduced into a groove in fluid communication with the opening. The groove is formed in a bottom surface of the base and has an open side at a front side of the base. The fanned air is then discharged from the front side of the base, blowing off saw dust on a cutting object so as to prevent dust from accumulating on a marking line on the cutting object.
