Dehumidifying apparatus
View Patent ↗The present invention relates to a general-purpose dehumidifying apparatus in which a housing having a dehumidifying member therein is applied to an object to be dehumidified (an electric light (such as a street lamp, a vehicle lamp, etc.), an outdoor or indoor electronic enclosure (such as power distributing equipment, communication equipment, security equipment, a solar system, etc.), and the like), and the dehumidifying apparatus removes internal moisture through an outer valve that opens and closes an outer communicating part of the housing (by closing the outer valve) in a case where the temperature of the object to be dehumidified is low and discharges the moisture of the dehumidifying member to the outside by opening the outer valve when the temperature in a lamp module rises in a case where the temperature of the object to be dehumidified is high. The dehumidifying apparatus, according to the present invention, comprises: a housing installed in an object to be dehumidified and having inner and outer communicating parts connected to the outside; a dehumidifying member mounted in the housing; and an outer valve that opens and closes the outer communicating part of the housing.
1. A dehumidifying apparatus comprising:
a housing installed in an object to be dehumidified and having an internal communication portion and an external communication portion, the internal communication portion and the external communication portion being connected to an outside of the housing;
a dehumidifying member installed in the housing;
an outer valve configured to open and close the external communication portion of the housing, and
an inner valve configured to open and close the internal communication portion of the housing,
wherein the outer valve comprises:
an outer opening/closing body displaced by temperature rise of the object to be dehumidified to open the external communication portion; and
an outer sealing body arranged between the outer opening/closing body and the external communication portion, the outer opening/closing body closing the external communication portion when the object to be dehumidified is cooled in an open state of the external communication portion,
wherein the inner valve comprises:
an inner opening/closing body displaced by temperature rise of the object to be dehumidified to close the internal communication portion; and
an inner sealing body arranged between the inner opening/closing body and the internal communication portion, the inner opening/closing body opening the internal communication portion when the objet-to-be-dehumidified is cooled in an closed state of the internal communication portion,
wherein at least one of the outer opening/closing body and the inner opening/closing body is formed of bimetal, and
wherein the object to be dehumidified or the housing further comprises a heater.
