Abstract:
A flow-through humidifier device comprising:a frame assembly for securing onto an air supply duct and having three side walls, a top and a bottom walls and a front cover wall, a first and a second of said side walls having an air inlet opening and an air outlet opening respectively; an evaporator assembly including a pad member adapted to be vertically disposed between and held by said top and bottom walls and being generally adjacent to said air inlet opening to substantially cover the same, a water supply member removably mounted to said top wall for supplying water to said pad member, and a water drain member mounted to said bottom wall to collect any excess of water from said pad member; said water supply member including a valve member controlled by an air temperature controller, said air temperature controller includes an electronic circuit electrically connected to a temperature sensor and timely pulses a solenoid valve of said valve member to allow for a specific amount of water to intermittently humidify said pad member for constant time intervals when the sensed temperature of said air supply duct is higher than a pre-determined set temperature, thereby humidifying hot air flowing through said pad member of said humidifier device.
