Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of use> The present invention relates to improvement of an electronic dehumidifier using an electronic cooling element.

<Prior art> Recently, in order to maintain the reliability of equipment, storage, etc. under high temperature and humidity environmental conditions, a dehumidifier is installed inside the equipment, storage, etc. The operation and control are performed to dehumidify and prevent dew condensation inside equipment, storage, etc., and an electronic dehumidifier is used as an optimum dehumidifier for that purpose.

FIG. 4 shows an embodiment of a conventional electronic dehumidifier used for this type of application, in which the dropping direction of the water droplets 6 is shown as downward, (a) is a longitudinal sectional view thereof, and (b) is cooling. It is a front view of a fin. The configuration of the electronic dehumidifier 20 will be described below with reference to the drawings.

Reference numeral 1 is an electronic cooling element, and a drainer 21 is provided at the lower end on the cooling surface side.
The cooling fin 2 provided with the cooling fin 2 is fastened to the radiation surface side by the bolts 19, and the radiation fin is extended above and below the dimension of the cooling fin. The heat radiation fins 3 are attached to the outer wall 31 by the frame 27 so that the heat radiation fins 3 are located on the outer side of the outer wall 31 of the device, the storage, etc.
Then, the air flow 9 is present in the space interposed between the fins 2 and 3.
Is filled with a heat insulating material 11 except for a ventilation passage portion, and has an airtight and heat insulating structure as a whole, an outer case 17 made of a metal on the inner side of the outer wall 31, and a metal-like mesh on the outer side. It is protected by an external mesh case 18 having a lattice-shaped opening. A heat radiating plate 4 is provided on the inner side of the upper extension of the heat radiating fin 3, and the outer case 17
An air passage is formed between the inner wall of the cooling fin 2 and the heat radiating plate 4 and communicates vertically from below to above for cooling and heating, and an air flow 9 flows through this ventilation passage from below to above. The outer case 17 is attached to the outer edge of the heat dissipation plate 4 by a bolt (not shown), and the outer mesh case is used as the heat dissipation fins 3.
Are fastened to each other. Inlet 13 at the bottom of the electronic dehumidifier 20
Is provided, and the exhaust port 14 is provided at the upper part.

10 is a fan for forced ventilation, which is used especially when the humidity is high.

Next, the operation of the electronic dehumidifier 20 having the above configuration will be described. The humid air 7 sucked in through the intake port 13 is cooled to below the dew point temperature when passing through the cooling ventilation path formed between the inner wall of the outer case 17 and the cooling fins 2 as the air flow 9 and becomes saturated. The resulting water vapor condenses on the surface of the cooling fin 2 to form a water drop 6, which is dropped from the drainer 21 of the cooling fin 2 and discharged from the drainage funnel 5 provided at the bottom of the electronic dehumidifier 20. A drainage hose is connected to the drainage funnel 5 and is discharged to the outside of the equipment, the storage, etc. through a discharge hole provided on the floor of the equipment, the storage, etc. On the other hand, the cooled and dehumidified airflow 9 rises and this time is heated and dried while passing through the ventilation passage for heating formed between the inner wall of the outer case 17 and the heat dissipation plate 4, The relative humidity decreases and the dry air 8 is returned to the inside of the equipment, the storage, etc. through the exhaust port 14 at the upper part.

As described above, by repeating the intake of the humid air 7 and the exhaust of the dry air 8 repeatedly, the internal humidity of the equipment, the storage, etc. is reduced to a predetermined value, and the dew condensation inside the equipment, the storage, etc. is prevented. can do.

<Problems to be solved by the invention> As described above, water drops are generated as a result of the dehumidifying action of the electronic dehumidifier, but since these are useless, it is necessary to discharge them from the inside of equipment, storage, etc. to the outside. With a drainage hose connected to a drainage funnel provided at the bottom of the electronic dehumidifier, it is discharged from the drainage holes drilled on the floor or side of the storage, or once inside the equipment, storage, etc. It is necessary to select one of the methods of storing it in the installed water tank and artificially discarding it outside the equipment at the time of inspection. When a facility intends to install an electronic dehumidifier as a measure to prevent condensation on existing equipment, various storage cabinets, etc., new drainage holes should be drilled on the floor and side walls of the equipment and cabinets as described above. ,
There is a problem that a drain hose must be laid down to the external drainage ditch, and when the water tank system is used, it is necessary to dispose of the water stored by periodical manual inspection, which is troublesome and costly. Therefore, there is a problem that the adoption of the electronic dehumidifier is avoided.

<Means for Solving the Problems> In order to solve the above problems, the present invention has one end located immediately below the drainer under the cooling fin and the other end penetrating the heat insulating material and the radiation fin at an inclination. Then, a water guide plate is provided so as to flow out of the electronic dehumidifier, and the water droplets are transferred to the outside of the equipment, storage, etc. through the water guide plate. Therefore, even if a water receiving tank is provided directly below the radiation fins and a drain hose is connected to the bottom of the water receiving fin, the water temporarily stored in the water receiving tank can be naturally stored in response to the case where there is no drain groove in the vicinity. It may be diffused into the outside air by evaporation. Furthermore, a dry auxiliary material (for example, gauze) having one end immersed in the water receiving tank and the other end hooked on the outer edge of the heat dissipation fin is used as the heat dissipation fin. The same effect can be expected even if it is sandwiched between the outer case and the outer mesh case, or if one end of the dried auxiliary material is not immersed in the water receiving tank but directly locked to the lower end of the water guide plate. .

<Operation> According to the present invention, since the lower end of the water guide plate inserted into the insertion port provided in the heat insulating material and the heat radiation fin is exposed to the outside of the equipment, the storage, etc., water droplets are stored in the equipment, the storage. It has been transferred from the inside to the outside and drained. Therefore, if you install a water tank just below the radiation fin and receive water drops once,
The treatment may be performed by connecting a drainage hose as usual, and it is also possible to perform the treatment by diffusing it into the surrounding air by natural drying by utilizing the capillary action of a drying auxiliary material such as gauze. In this case, one end of the dried auxiliary material may be put in the water receiver, or the same effect can be obtained by directly extending it from the lower end of the water guide plate.

<Embodiment> The present invention will be described below based on an embodiment shown in FIGS. 1 to 3.

1 and 2 are cross-sectional views of an essential part showing an embodiment of an electronic dehumidifier according to the present invention, in which the dropping direction of the water droplets 6 is shown as downward as in FIG. 4, and FIG. It is a perspective view of the synthetic resin water guide plate used in the Example.

The same components as those of the electronic dehumidifier shown in FIG. 4 described before in the figure are designated by the same reference numerals, and thus the description will be omitted to avoid duplication of description.

The water guide plate 25 shown in FIG. 3 is made of a synthetic resin having a plate thickness of about 3 to 5 mm, which is arranged immediately below the cooling fins 2. The water receiving surface, which is the upper surface of the water guide plate, has fine grooves 26 for sinking water flowing down. Multiple pieces are engraved in parallel with. According to the present invention, as shown in the embodiment of FIG. 1, the outer wall 31 of the side wall surface or rear wall surface of equipment, storage, etc.
An opening for exposing the radiation fin 3 is provided in advance, and the electronic dehumidifier 20 according to the present invention is made to project the radiation fin 3 and the water tank 24 to the outside of the outer wall 31 from the inside so that the frame 27 is covered with the outer wall 31. By installing it so that it closely adheres to the inner surface of
Although this opening is closed, the water guide plate 25 has an insertion opening 28 provided in the heat insulating material 11 and an insertion opening provided in the radiating fin 3.
Since it is inserted in 29 and penetrates from the cooling fin 2 side inside to the outside of the heat radiation fin 3, the water droplet 6 dropped on the water guide plate 25 flows down by the narrow groove 26 arranged on the surface, and , It can be transferred from the inside of the storage to the outside and discharged to the outside.

In the second embodiment shown in FIG. 2, the water stored in the water receiving tank 24 is returned to the atmosphere outside the equipment, storage, etc. by natural evaporation, and as shown in the figure, it is generally called gauze. Dry auxiliary material formed by stacking multiple layers of woven cotton cloth
Is sandwiched between the radiating fins 3 and the external mesh case 18, one end is immersed in the water receiving tank 24, and the other end is hooked on the upper edge of the radiating fins 3. With this configuration, the water droplets 6 generated by the dehumidification flow down the narrow groove 26 of the water guide plate 25 and are temporarily stored in the water receiving tank 24, and at the same time they permeate into the dry auxiliary material 30 and the capillary phenomenon causes the dry auxiliary material 30 to flow. Move to the upper part. However, since the dry auxiliary material 30 is sandwiched between the radiation fins 3 and the exterior mesh case 18, and the exterior mesh case 18 is also fastened to the radiation fins 3 with bolts not shown, the dry auxiliary material 30 is heated from both sides. As the water diffuses upward, it vaporizes faster and evaporates. Evaporated water is the water tank
Since the water is constantly replenished from one end immersed in the water 24, when the dehumidifying operation is continued for a long period of time, the water in the water receiving tank 24 is usually hardly observed.

In the embodiment of FIG. 2, the case where the water receiving tank 24 for receiving the water droplets 6 from the water guiding plate 25 is provided has been described. However, the water receiving tank 24 is not provided at the lower end of the water guiding plate 25, and the drying auxiliary material 30 is directly used. One end may be locked. Of course, in this case, the water droplets 6 move directly from the water guide plate 25 to the drying auxiliary material 30 and evaporate into the atmosphere in the same manner as described above.

<Effects of the Invention> According to the present invention, it is possible to discharge water from the inside of equipment, storage, etc. to the outside with a simple structure that only one water guide plate is added to the lower part of the cooling fin. Therefore, it is extremely easy to drain the water droplets generated by the dehumidification operation, eliminating the need to install a drainage hose to the drainage ditch by drilling a drainage hole on the floor or side of equipment, storage, etc. Since the dehumidified water is evaporated by using the heat radiation of the fins, it is not necessary to regularly inspect the water stored in the storage tank or artificially dispose of it, or the storage tank itself can be eliminated. The cost is not high, and the adoption of the electronic dehumidifier is effective.
