Abstract

PURPOSE:To prevent overflow of water owing to the excessive feed of water through display of a state to fully fill a tank with water by a method wherein, when water in the water tank runs short and water is supplied through an upper surface opening part to feed water in the water tank, a display means is lighted ON according to a water level in the water tank. CONSTITUTION:When an ultrasonic vibrator 6 and a motor 8 are energized, water fed in a water tab 5 from a water tank 20 is atomized by means of the ultrasonic vibrator 6. Meanwhile, air sucked through a suction port 2 with the aid of a blower 10 is guided in a space, surrounded with an inner case 4 and a partition member 14, through a blast cylinder body 13, and water atomized by means of the ultrasonic vibrator 6 is sprayed through a spray port 18 to the outside of a body 1. When water in the water tank 21 runs short, water is supplied from above and fed in the water tank 21 through a decoration object 31 and a lattice form member 30. Along with the feed of water to the water tank 21, a display device 32 is moved upward, and when the water tank 21 is brought into a state to be approximately fully filled with water, a reed switch 37 approaches and positioned facing a magnet 36 and the reed switch 37 is closed. A lamp 39 is lighted ON through the feed of a power from a battery 33 to display a state to be fully filled with water.

Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to improvements in humidifiers.
