Description

DEHUMIDIFICATION APPARATUS

The present invention relates to a dehumidifying device,

More particularly, the present invention relates to a dehumidifying device which is applied to a dehumidifying target body (lighting such as a street lamp or a vehicle lamp, distribution, communication equipment, security equipment, outdoor equipment such as a solar system, When the dehumidifying target object is at a high temperature, the temperature of the lamp module is raised and the moisture of the dehumidifying material is heated to the outside And,

Furthermore, when the temperature of the dehumidifying object is further increased by introducing an inner valve in addition to the outer valve provided outside the dehumidification member of the housing, the moisture of the dehumidifying member is more completely removed by closing the inner valve at the time of opening the outer valve And more particularly, to a general dehumidifying device in which the inner and outer valves are made of bimetallic material to perform non-dynamic opening and dehumidification.

Various dehumidifying objects such as street lamps, vehicle lamps, lighting, distribution, communication equipment, security equipment, solar systems, and the like are required to remove moisture in the enclosure to protect internal circuits and devices.

Specifically, it is ideal to apply a sealing structure for waterproofing in case of rain in the case of an electronic enclosure such as a control panel or an electric switchboard, in particular, an outdoor enclosed electronic enclosure. However, contraction and expansion of air in the enclosure It is common to introduce a vent for pressure balance in order to prevent breakage of various parts, elements, etc. in the electronic enclosure due to internal pressure fluctuations.

When such a vent is applied, the electronic enclosure communicates with the air, and therefore there is a possibility of condensation in the enclosure due to the temperature difference.

For example, a vehicle lamp, which can be classified as an electronic enclosure, has an open structure for ventilation, not an airtight structure, in order to relieve internal air pressure that expands with an increase in internal temperature during lighting, Condensation phenomena often occur due to differences in temperature and humidity.

If the condensation inside the lamp is repeated and the condensation state is not solved, problems may arise in the nature of the lamp (irradiation angle, etc.), which may lead to a bad smell of safety and electrical insulation, which may cause additional problems .

To solve this problem, Japanese Patent Application Laid-Open No. 10-2006-0067597 (published on June 20, 2006) (a head lamp for a vehicle in which a moisture removing means is formed)

This patent discloses a vehicular head having a moisture removing means for removing moisture generated on the inner surface of a headlamp lens cover installed on the front surface of the headlamp when the headlamp is installed in a headlamp housing on both left and right sides of the vehicle, Regarding the lamp,

Specifically, a headlamp for a vehicle, which is installed on an inner surface of a headlamp lens cover formed on a front surface of the headlamp and has a height difference at both ends and formed in a round shape, A moisture removing means installed; And an overheat preventing unit that can cut off the current when the current flowing during operation of the moisture removing unit is excessive.

However, it is insufficient to effectively discharge the air inside the lamp only by the moisture removing means composed of the heater of the hot line, and there is a safety problem even when it operates at a temperature higher than the lamp operating temperature.

In addition, there is a dehumidification method of a headlamp for a vehicle as disclosed in Japanese Patent Application Laid-Open No. 10-2012-0050268 (published on May 18, 2012)

The patent discloses a diffuse reflection measuring method for measuring irregular reflection of a light source emitted from a light through a photodiode sensor mounted on a head lamp of a vehicle. A diffuse reflection comparison step of comparing the diffuse reflection result measured in the diffuse reflection measuring step with a first reference value; A power driving step of driving power through a controller interlocked with an ECU provided in the vehicle when the diffuse reflection result value measured in the diffuse reflection comparison determination step exceeds a reference value; And a moisture removal step of dehumidifying the inside of the head lamp by operating a fan interlocked with the controller during power operation in the power driving step.

However, it is considered to be an intricate technique to realize a realistic technology of dehumidifying by operating only a fan in a vehicle lamp that always takes a ventilation structure.

Next, Patent Registration No. 10-1366848 (registered on Feb. 14, 2014) [Automobile head lamp dehumidifier]

The present invention relates to a head lamp dehumidifying device installed in a headlamp housing of an automobile and circulating air inside a headlamp to remove moisture, the headlamp dehumidifying device being installed in a discharge hole drilled for discharging the air inside the lamp housing, A moisture absorbing portion for absorbing or adsorbing moisture contained in the air inside the head lamp, and an air blowing portion for forcibly circulating the air in the head lamp to the inside of the head lamp, .

However, this patent also fails to provide a solution to the problem that the moisture absorption part is caught not only in the inside of the lamp but also in the outside moisture due to the characteristic of the lamp structure of the vehicle, which always takes a ventilation structure.

Further, Patent Registration No. 10-0836307 (registered on June 02, 2008) [Dehumidification structure of vehicle head lamp using Bentonai natural clay pack]

This patent relates to a dehumidification structure of a vehicle headlamp using a Bentonai natural clay pack,

In particular, the Bentonite natural clay pack is used as a desiccant to absorb moisture at a temperature of 50 ° C or lower, and to evaporate moisture at 50 ° C to 100 ° C, thereby enabling dehumidification of the headlamp.

More specifically, as a dehumidifying structure of a headlamp for a vehicle, a bentonite natural clay pack which absorbs moisture at a temperature below a predetermined temperature range and evaporates moisture at a predetermined temperature range, and which is repeatedly regenerated, and a head lamp bezel A bentonite natural clay pack receiving space in which the bentonite natural clay pack can be accommodated in a lower portion of a side of a side of a head bulb side of a head lamp bulb, a fixing bracket for fixing the bentonite natural clay pack to a head lamp bezel, And FIG.

However, this patent does not provide a solution to the problem of moisture absorption in the outside air circulating inside the same lamp as the above two prior arts, except for the specificity of a dehumidifying member composed of a bentonite natural clay pack.

Therefore, the present invention can be applied to various dehumidifying objects such as a street lamp, a lamp for a vehicle lamp, a power distribution device, a communication device, a security device, an outdoor or indoor electronic enclosure such as a solar optical system, and more specifically, And it is an object of the present invention to provide a universal dehumidifier capable of preventing corrosion or damage of internal components or elements due to inevitable condensation of a dehumidifying object such as various electronic enclosures.
