Title: Humidification device
Inventor: IWAHASHI HIROSHI
IPC: F24F6/00
Filed: 1988-01-29
Abstract: PURPOSE:To make it possible to carry out sanitary humidification by installing a filter, which is made of porous membrane and does not allow the passage of various germs breeding in water, but allows the passage of water only, into a water supply channel which leads to a humidification device installed in a water tank. CONSTITUTION:When a humidification device is operated, an oscillation unit 5 and a vibrator 6 atomize water 10 in a water tank 2, and the atomized water is discharged indoors by the action of a blower unit 7. However, various germs contained in city water are increased in a tank 4 of humidification equipment or a water tank 2. When the water 10 which contains the various germs passes through a filter 13, the various germs are caught up, since their sizes are larger than the mesh size of the filter when their sizes are compared. As a result, clean water without the various germs is supplied to the vibrator side 6. This clean water 10 is further atomized. It is therefore, possible to carry out clean humidification.
