ABSTRACT:
BACKGROUND OF THE INVENTION
This invention concerns dehumidifiers for use especially in connection with bathrooms and the like. It is well known that when an individual is taking a shower, a great deal of water vapor accumulates and condenses on the various surfaces of the bathroom. Most bathrooms have exhaust fans for removing the undesirable humid air; but, exhaust fans simply exhaust moist air from the room and replace it with air from an adjacent room. Since bathroom doors are customarily closed, it is inefficient and difficult for an exhaust fan to pull air from an adjacent room. If the door is left open, the exhaust fan might become effective but air from an adjacent room is typically undesirably cold.
Besides exhaust fans, dehumidification is accomplished by the use of a dehumidifier or refrigeration system wherein the evaporator acts as a cold surface on which moisture condenses and the condenser acts as a heat exchanger to rewarm the air before it passes back into the room. Such dehumidifiers are typically too large to fit conveniently in a typical bathroom.
SUMMARY OF THE INVENTION
By this invention, dehumidification in a bathroom is accomplished when air from an adjacent room enters the device and is selectively directed into contact with a heat exchanger and then forced into the bathroom by fan means.
