Abstract

The utility model relates to an electrical moisture absorbing device, which belongs to the field of the manufacture electric appliances. Two arms of a U-shaped pipeline are tightly clamped and is leaned and connected to the cold end and the hot end of a semiconductor cooling electric pile. The interior of the pipeline of one arm is a condenser structure, and the interior and the exterior of the pipeline of the other arm are radiator structures. When the electrical moisture absorbing device is arranged in a closed container to be processed by moisture absorbing and drying treatment, and when air in the closed container flows across the U-shaped pipeline, moisture in the air is heated to improve temperature to became dry heat air after the moisture in the air is condensed and collected to achieve moisture absorbing and drying purposes.

Description

Electrial dehumidizer

The utility model relates to a kind of Electrial dehumidizer, belongs to electrical equipment and makes the field.

In the fields such as people's daily life, work and scientific research, there be depositing of many article tighter, special be afraid of to mildew, go bad, ectocrine resistance etc. because of humidity causes for humidity requirement.In order to address this problem, adopt sealing to add chemical hygroscopic agent or the like, the one, inconvenient, the 2nd, must periodic replacement, otherwise lost hygroscopicity after losing efficacy and become unreliable, impracticable.The characteristics of this Electrial dehumidizer are: volume is small and exquisite, compact, is positioned in container, the vessel such as the case of preserving article, cabinet, cylinder, bottle, barrel polybag, can absorb moisture after the energising, keeps dry.Adopt low-voltage power supply, safe in utilization, the power consumptive province.

Below in conjunction with description of drawings basic structure of the present utility model and operation principle.

The pipeline of a U-shaped ［ 1 ］ clamps semiconductor refrigerating pile original paper ［ 3 ］ across electric-insulation heat-conduction layer ［ 2 ］, is treated to condenser ［ 4 ］ structure in the pipeline that the cold junction of semiconductor refrigerating pile original paper ［ 3 ］ leans on mutually, and pipe is outer to have heat-insulation and heat-preservation and handle cover.In the pipeline that its hot junction is leaned on mutually, be treated to radiator ［ 5 ］ structure.Put at the end of U-shaped pipeline recess and to connect a condensate collector ［ 6 ］, the little blower fan of a low noise can also be set in the U-shaped pipe.Outside humid air is by the U-shaped pipeline time, and behind the moisture that freeze-outs in condenser, heat absorption becomes the heated dry air discharge in the hot-side heat dissipation device again, has promptly reached the purpose of moisture absorption.

Outside the pipeline of hot junction, also radiator structure can be set.Simultaneously can lay the adjustable electrothermal relay in electrothermal relay or contact, to limit hot-side temperature in the hot junction.The modulation hot-side temperature has also just been modulated the temperature and the air aridity of discharging air, also can protect the semiconductor refrigerating pile not to be damaged.

To collect airborne moisture in order condensing as much as possible, can to adjust refrigerating speed and cryogenic temperature by adjustment (partly realizing) at low-voltage dc power supply to the cooling pile operating current.The temperature of cold junction condenser can be low to moderate subzero, forms if any frost or ice, contrary operation that can be by cooling pile or make the cooling pile break-off and blower fan still to work with defrost and ice be that water is collected.The outer heat-insulation and heat-preservation that will carry out of the pipeline of condensation end is handled.

Air is caught a cold in the condenser of U-shaped pipeline and density increases, and proportion must sink greater than extraneous air, and in the radiator hollow aspiration heat of U-shaped pipeline and density reduces, proportion must rise less than outside air.So this Electrial dehumidizer is when work, outside humid air enters the discharge of U-shaped pipeline and dry air, must not drive (blower fan driving) with external force again and can constantly enter the hot junction discharge from cold junction.Just note the U-shaped mouth of pipe is placed towards the top.If in order to quicken the circulation of air, can be in the U-shaped pipeline suitable location, for example in U-shaped pipe bottom near little blower fan of low noise of radiating end one side installation.By the blower fan driving outside air is continued to flow through the U-shaped pipe, absorb airborne moisture content.

Can put some small hoses in the exit of heated dry air the heated dry air branch is guided to each moist place or each corner in the vessel, it is better to absorb wet circulating effect.As only dry air being drawn out to the purpose that also can reach hygroscopic desiccation in the vessel that need dry storage product.

The refrigeration characteristics of semiconductor refrigerating pile are that volume is little, efficient is high, noiseless, nothing wearing and tearing, long, good reliability of life-span.In addition, need the power supply of configuring direct current low-tension supply, thus will be to civil power step-down rectifier (the filtering ripple coefficient require less than 20%), this type of circuit and device are much used always, and the professional and technical personnel can understand and realize, so do not describe in detail.

Figure one and figure two are two embodiment.

Among the figure one: ［ 1 ］ is the U-shaped pipeline, ［ 2 ］ be the electric-insulation heat-conduction layer, ［ 3 ］ semiconductor refrigerating pile original paper, ［ 4 ］ be condenser (be surrounded by heat-insulation and heat-preservation outward and handle cover), ［ 5 ］ radiator (being laid with electrothermal relay), ［ 6 ］ condensate collector (can be provided with the full sensing electrode of water, connect acoustic-optic alarm, all be prior art), the little blower fan of ［ 7 ］ low noise, ［ 8 ］ U type pipeline air intake (being the cold junction mouth), ［ 9 ］ U type pipeline air outlet slit (being the hot junction mouth), ［ 10 ］ be sleeved on some small hoses on the mouth of hot junction, ［ 11 ］ electric source connecting box, ［ 12 ］ step-down rectifier filtering Dc low voltage power supply.

Among the figure two: ［ 13 ］ are U type pipeline, and ［ 14 ］ are the electric-insulation heat-conduction layer, ［ 15 ］ semiconductor refrigerating pile, and ［ 16 ］ condenser and heat-insulation and heat-preservation are handled cover, ［ 17 ］ radiator and hot protective relay, ［ 18 ］ condensate collector, ［ 19 ］ electrical terminal block.

The topmost strong point of the utility model is that volume is little, uses flexibly especially, puts in the ready-made storage container and gets final product hygroscopic desiccation.For example put into mug, tea case, wardrobe, grain cylinder, medicinal material cylinder case etc., put into the recording videotape in addition and preserve cabinet etc.Do not need special facility, can implement hygroscopic desiccation reaching the internal memory article in the existing preservation container.So be widely used arbitrarily, family, shop, pharmacy, scientific experiment chamber etc. all are suitable for.
