HUMIDIFIER WITH WATER FLOW CONTROL BETWEEN AN UPPER TANK AND A LOWER RESERVOIR

摘要

The humidifier has an upper tank and a lower reservoir. A liquid level switch in the lower reservoir works in conjunction with a valve in a water passage between the upper tank and the lower reservoir in order to provide an automated flow of water to the lower reservoir during operation of the humidifier. The upper tank is unsealed, such that air in the upper tank may equalize with an ambient air pressure. The humidifier can be top-filled allowing that the upper tank to be permanently affixed to the base of the humidifier.
