Abstract
A household humidifier comprising a closed water tank, a demineralizer, an air exchange pipe for introducing the outside air, a housing defining a chamber, and a coiled spring. The demineralizer has a container containing ion-exchange resin. The water tank has a water supply port through which the demineralizer and the air exchange pipe can be inserted into the tank. One hollow end of the container is rotatably connected to the chamber such that the container is in communication with the chamber. The container is biased downward by the spring so that the container always lies on its side.
