Provided is a coating method, including the steps of: applying a coating composition including inorganic fine particles and fluororesin particles in an aqueous medium onto a material to be coated; drying the coating composition on the material to be coated to remove the aqueous medium, thereby forming a porous film formed of the inorganic fine particles, the porous film having the fluororesin particles therein and having voids; and applying one or more water-soluble substances selected from the group consisting of a water-soluble surfactant and a water-soluble polymer onto the porous film, thereby filling the one or more water-soluble substances in the voids of the porous film. According to the coating method, there can be formed a coated article having a coating film which exhibits the excellent effect for inhibiting the attachment of oil stains for a long period and from which, even if oil stains are attached, the oil stains can be easily removed by wiping or washing with water.

摘要:
Disclosed is an air conditioner coated by the coating composition to the resin-made components where due formation occurs upon the cooling operation, provides the antifouling performance against various stains, restrains enlargement of droplet, and provides an excellent long-term durability (sticking property and peeling off property) all at the same time. The air conditioner of the present embodiment forms a coating film 103 to surfaces of resin-made components and resin-made components installed to a rear flow side of the heat exchanger, includes the silica ultrafine particles 101 and the fluororesin particles 102, and provides, within the coating film 103, a silica film 104 comprising the silica ultrafine particles and the fluororesin particles 102 partially exposed from a surface of the silica film 104 in dots, and an exposed area of the silica film 104 is greater than an exposed area of the fluororesin particles 102.

摘要:
A pleasant sound making device processes temporal variation characteristics in nature such that a frequency component and a peak frequency component in a frequency band which coincide with or are approximate to a housing of an indoor unit provided with a driving part (a fan, a motor, etc.) do not coincide with or are not approximate to the housing, on the basis of subjective view and physiological response evaluations of humans, and operates the driving part with a signal based on the processed waveform.
