Abstract
A dry out mechanism for controlling a humidifier is disclosed. The mechanism includes a float and a switch. The float contacts the switch when the float is within an operating range. The movement of the float can be manually changed between settings to achieve normal operation or dry out operation of the humidifier. In the normal operation, the float activates the switch based on the fluid level within the humidifer's reservoir. In the dry out setting, the float activates the switch independent from the level of fluid within the reservoir so that the humidifier depletes the reservoir and components of fluid.
Claims6
A humidifier, comprising:
- a reservoir adapted to contain fluid;
- a wick situated to be wetted by fluid contained in the reservoir;
- a fan operable to move air through the wick;
- a switch for controlling operation of the fan;
- a float movable between a first position to activate the switch and a second position to deactivate the switch;
- and
- a float holder connecting the float to the humidifier, the float holder having a first setting in which the float is movable between the first and second positions in response to the level of fluid contained in the reservoir, and having a second setting in which the float is fixed in the first position independent of the level of fluid contained in the reservoir.
