Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a dehumidifier using a deliquescent hygroscopic agent, and more particularly to a dehumidifier provided with forced ventilation means using an electric fan.
[0002]
[Prior art]
Conventionally, for example, in order to remove moisture in a storage space such as a closet at home, a clothes closet or a clog box, and to protect the stored items from damages such as molds, the liquid is sucked and liquefied. Various dehumidifiers using deliquescent absorbents such as calcium chloride, magnesium chloride, and phosphorus pentoxide have been used.
[0003]
These dehumidifiers are roughly classified into two types. One is a natural ventilation type in which the moisture is transferred from the air circulating by natural convection to the moisture absorbent, and the other is a forced ventilation type in which the fan is rotated by power to forcibly suck and exhaust air.
[0004]
As a known example of the former natural ventilation type, as described in Patent Literature 1 below, a flange for suspending the edge of a container body having an open upper surface, and a hole for deliquescent droplets or A space is provided between the lower part of the moisture absorbent container provided with the groove and the bottom of the container body to form a storage room for absorbing moisture and storing liquefied deliquescent liquid, and a net covering the ceiling surface Moisture is absorbed through a cover formed of a breathable sheet such as a body or a nonwoven fabric. In order to prevent the deliquescent liquid accumulated in the storage chamber from flowing to the outside when the container falls, a method for using a thickener has been devised.
[0005]
Many other dehumidifiers using a deliquescent hygroscopic agent have been proposed and put into practical use, but have almost the same configuration. However, there are few examples of preventing spills simply by imparting viscosity to the deliquescent liquid with a thickener, and many natural ventilation type dehumidifiers as lids have breathability but prevent the exudation of moisture, In most cases, an air-permeable / water-impermeable sheet is used and the periphery is hermetically sealed to the container body.
[0006]
A known example of the latter forced-ventilation type is described in Patent Document 2 below, which includes an air inflow cylinder in which a motor and a fan are mounted in a central portion, and an air outflow port around the air inflow cylinder. The lid is configured by mounting components such as batteries, and is screwed into a container body that has a slightly narrow opening and contains a deliquescent hygroscopic agent and stores deliquescent liquid. Is done.
[0007]
In such a configuration, as a result of the forced ventilation in which the air forcibly sucked and exhausted by the fan touches the dehumidifier, the dehumidifying ability is remarkably improved as compared with the natural ventilation type dehumidifier. However, in order to secure the air flow path, the opening is inevitable, and depending on the amount of deliquescent liquid that has accumulated in the container body when it is turned over, it overflows from the slightly narrowed opening and overflows to the outside. Will flow out.
[0008]
Therefore, recently, as in the conventional example described in Patent Literature 3 below, a device has been proposed in which the container body is configured to be hermetically sealed to prevent the deliquescent liquid from flowing out.
[0009]
That is, an intake port and an exhaust port are respectively provided at the left and right ends of the upper surface of the container main body which can be sealed, and both openings are opened and closed by a ventilation passage closing plate which acts as a seal. A rod-shaped movable body corresponding to a valve rod is fixed to the ventilation path closing plate, and the ventilation path closing plate is urged by a spring means in a direction to close the opening, and the tip of the movable body slightly extends from the bottom of the container body. It protrudes.
[0010]
Then, when the dehumidifier is correctly positioned, the movable body connected to the ventilation path closing plate is pushed up against the urging force of the spring means, and the intake port and the exhaust port are opened, so that the lid is closed. The forced ventilation of the provided fan works, and efficient dehumidification is performed.
[0011]
If the dehumidifier falls down, the movable body, which has been pushed in by the weight of the container body and opened the opening, returns to the original position by the spring urging force, so that the intake port and the exhaust port are closed, and the container is closed. The main body is in a sealed state to prevent the outflow of deliquescent liquid.

[Problems to be solved by the invention]
However, each of the two types has advantages and disadvantages, and the natural ventilation type dehumidifier has a relatively simple structure, can be manufactured at low cost, and can be disposable. There is a problem that the dehumidifying ability is extremely low. Also, recently, due to the increasing awareness of environmental issues, in the case of disposables, there are various ideas on the side of supplying the dehumidifier, such as devising a method to reduce the material of the discarded part and considering materials that do not cause environmental degradation. There is a problem that it is difficult to think of a standard one.
[0016]
On the other hand, in the forced-ventilation type dehumidifier, the air flow generated by turning the fan with a motor is passed from the separately provided intake port to the exhaust port, and the dehumidifier is increased. Openings are essential.
[0017]
Therefore, since it is necessary to prevent the deliquescent liquid from flowing out, a seal member must be provided at each opening, and the structure is inevitably complicated, and there is a disadvantage that the cost is extremely high as compared with the natural ventilation type.
[0018]
In addition, by using a refilling method for the absorbent, the only part to be discarded is the packaging of the dehumidifying agent for replenishment, which has the advantage of reducing the number of waste components and contributing to resource saving compared to the disposable method. Since the dehumidifying agent is exclusively used, there is a disadvantage that it is rather expensive.
[0019]
The present invention has been devised in view of the above-mentioned conventional technical problems, and incorporates the advantages of the two types, has excellent dehumidifying ability as a forced-ventilation type, and has a breathable and water-impermeable sheet even when it falls down. Like the closed natural ventilation type, the upper surface itself is a liquid leakage prevention means, or it is equipped with extremely simple and inexpensive liquid leakage prevention means, so that dehumidification performance is high, low cost, and replacement replacement An object of the present invention is to provide a dehumidifier excellent in versatility of a dehumidifier.
[0020]
[Means for Solving the Problems]
The present invention separates a lid portion containing a ventilation mechanism in a forced-ventilation type dehumidifier, which has conventionally been integrally formed, and a sealed container portion having a partition for containing a desiccant, a fan, a motor, and a battery. The lid part that contains the elements required for forced ventilation, such as, is integrated into an independent ventilation unit. On the other hand, conventionally, the closed container part, which is mainly located at the lower part of the lid part and mainly consists of a partition for storing the moisture absorbent and a storage part for storing the deliquescent liquid, The container is hermetically sealed with a sheet or an independent container unit provided with a liquid leakage prevention means such as one simple check valve.
[0021]
By adopting such a configuration, the present invention adopts a form in which an independent ventilation unit is located above a conventional natural ventilation type dehumidifier, and guides only one of intake or exhaust to the container unit, It is an object of the present invention to provide a forced-ventilation type dehumidifier which can reduce or simplify the means for preventing liquid leakage at the openings required at two places and reduce the cost while maintaining the dehumidifying performance.
[0022]
Specifically, in the present invention, a power source such as a dry battery is mounted on a resin housing, the motor is further fixed by a tightening means such as a screw, and an appropriate means such as press-fitting into a rotating shaft of the motor is adopted. A resin fan is mounted, and the rotating fan is configured so as to minimize the gap between the rotating fan and the casing and reduce leakage with a labyrinth structure or the like. Further, the casing may be provided with a connection port at the center thereof, which may be integral with or separate from the casing. For example, a bell mouth-shaped suction port or an otherwise flexible pipe or hose may be connected to the suction port. And At the position facing the outer periphery of the fan of the casing, an opening as wide as possible is secured and used as an exhaust port. Further, the casing has a concentric circular fitting structure, and is assembled concentrically with the resin casing to avoid contact with the casing whose gap is reduced as much as possible when the fan rotates. In order to attach the air supply / exhaust means configured as described above to a wall surface or a ceiling surface, a metal or resin suspension device is provided, and a ventilation unit is configured and disposed above the dehumidifying unit. A magnet, a magic tape (registered trademark), or the like may be appropriately used as the suspension tool.
[0023]
On the other hand, a transparent or translucent resin container having an open upper surface is formed with a flat flange at the upper edge, and the upper edge is sealed with a liquid leakage preventing means made of a gas-permeable and water-impermeable sheet. Although it is sealed and covers the upper surface, a resin partition is also provided immediately below the liquid leakage preventing means, and the partition has a hole or groove for deliquescent droplets on the bottom surface, and calcium chloride , Magnesium chloride, phosphorus pentoxide, etc., constitute a storage section for deliquescent hygroscopic agents. The deliquescent moisture absorbent is stored in the partition beforehand before being hermetically sealed. In most cases, a natural ventilation type dehumidifier that is supposed to be completely disposed of and a container unit having the same configuration are arranged near the ventilation unit, and both functions as a dehumidifier.
[0024]
That is, the housing of the ventilation unit is placed on the upper edge of the container unit, and both units are fixed by an appropriate method such as banding. At this time, the bell mouth-shaped intake port of the ventilation unit is If the fan is driven so as to contact the liquid leakage prevention means covering the upper surface of the container, the liquid leakage prevention means has air permeability, so that the air inside the container unit is sucked from the part where the intake port contacts, Air containing moisture flows into the container unit from the portion. In other words, the surrounding air around the deliquescent moisture absorbent is forcibly ventilated, so that a container unit having the same configuration as a natural ventilation type dehumidifier can achieve the same dehumidifying capacity as a forced ventilation type. In addition, assuming a fall, the top surface of the container unit is covered with a ventilating / non-permeable liquid leakage preventing means, so that the deliquescent liquid does not flow out similarly to the natural ventilation type.
[0025]
In addition, as described in the previous section, the present invention sucks air inside the container unit through the air-impermeable and water-impermeable sheet acting as a liquid leakage preventing means by the power of the fan. However, the dehumidifying effect is still obtained, and of course, the deliquescent liquid does not flow out.
[0026]
Further, in the present invention, a bell mouth-shaped intake port of the ventilation unit is replaced with a connection port for connecting a flexible pipe or hose, and a flexible pipe or hose of a required length is connected to the connection port. Further, the tip is detachably attached to the container unit.
[0027]
That is, if the shape of the tip is a bell mouth and it comes into contact with the liquid leakage prevention means that covers the upper surface of the container unit, the above-described case of the ventilation unit is placed on the upper edge of the container unit, and a band is formed. The same operation and effect can be obtained as when both units are fixed by an appropriate method such as hanging.
[0028]
Next, to describe a method for easily attaching the tip of a flexible pipe or hose to the container unit, the central part of the partition of the container unit is formed into a hollow cylindrical shape to form an intake pipe. The upper end surface of the intake pipe is at the same height as the upper edge of the container unit, and is tightly sealed with a gas-permeable / non-permeable sheet. Instead, the lower end surface of the intake pipe is tightly sealed with a gas-permeable / water-impermeable sheet. That is, there is a cylindrical hole in a part of the upper surface of the natural ventilation type dehumidifier, the hole is an outlet of the intake pipe, and the inlet side is tightly sealed. If the tip of a flexible pipe or hose is inserted tightly into this intake pipe so that it does not come off easily, the above-mentioned ventilation unit housing is placed on the upper edge of the container unit and banded. The same operation and effect as when the two units are fixed by an appropriate method can be obtained.
[0029]
Instead of the container unit having a disposable structure described so far, a container unit to be used repeatedly will be described. The container body has a wide-mouth bottle shape, and a large-diameter packing lid is screwed. And sealed. The lid is formed in a donut shape having a hole at the center, and the hole at the center is closed by a gas-permeable and water-impermeable sheet having a strong adhesive applied to the periphery. A middle partition for storing the dehumidifying agent is provided at the middle stage inside the container body, and refilling and replacement is performed from the wide mouth of the bottle-shaped container. An inlet for inserting the tip of a flexible pipe or hose is provided at the shoulder of the jar-shaped container body. In view of the above, liquid leakage prevention means for preventing outflow of deliquescence is required.
[0030]
In the present invention, a rubber check valve is provided which is pushed open at the tip when a flexible tube or tube is inserted and closes the opening when the tube is removed. If a container unit and a ventilation unit that are repeatedly used with such an idea are used in combination, the casing of the ventilation unit is placed on the upper edge of the container unit and a suitable method such as banding is used. The same operation and effect as when both units are fixed can be obtained.
[0031]
In the device of the preceding paragraph, the horizontal cross-sectional shape is basically a circular container body. However, as described for the container main body with a horizontal cross-sectional shape, it is configured such that the intake port is provided at the sharp end of the droplet shape. Thus, when the flexible pipe or hose comes off and falls down, the opening is always on the upper side as in the case of rising and spilling, so that the outflow of deliquescent liquid can be prevented.
[0032]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a vertical section of the ventilation unit 1, and FIG. 2 shows a vertical section of the container unit 4. The ventilation unit 1 is made of a light-weight and highly rigid material such as a substantially cylindrical resin. 5 is largely divided into upper and lower portions by a base portion 51 formed across the middle stage, and a motor 6 passes through a rotary shaft 61 through a through hole 52 provided substantially in the center of the internal base portion 51, and a screw or the like is formed. The battery 7 which is a driving power source of the motor 6 is attached to the base portion 51 as necessary, one or more as needed.
[0033]
The upper surface of the housing 5 is provided with a cover 53 covering the motor 6 and the battery 7, and a suspension tool 8 such as a hook made of metal or resin for holding the ventilation unit 1 on a ceiling surface or a wall surface. In addition, although the hook was illustrated as the suspension tool 8, a magnet, a magic tape, or the like may be used.
[0034]
The back surface of the base portion 51 to which the motor 6 and the dry battery 7 are attached also serves as a part of the air path, and faces the back surface of the fan 9 made of light metal such as resin or aluminum with a slight gap. ing. A boss portion is provided at the center of the back surface of the fan 9, mounted on the rotating shaft 61 of the motor 6 by an appropriate method such as press fitting, and driven to rotate by the motor 6.
[0035]
Further, the surface of the fan 9 has a large opening 10 at the center, which constitutes an air inlet. The front surface of the fan 9 faces the casing 11 with a very small gap like the rear surface, and together with the rear surface of the base portion 51, constitutes an air passage. The opening corresponding to the opening 10 of the fan 9 is provided to form a connection port 12.
[0036]
The outer periphery of the casing 11 has a circular shape, and is fitted to the spigot portion 13 provided inside the housing 5, and concentric with the fan 9. Therefore, the inner surface of the casing 11 facing the surface of the fan 9 is formed. The gap can be narrowed, and in addition, by adopting, for example, a labyrinth structure (not shown) on the two faces facing each other, it is possible to further reduce the air flow passing through the narrow gap and leaking.
[0037]
The connection port 12 is connected to a bell mouth-shaped suction port 14 made of rubber, for example, and forms an intake port 15.
[0038]
The lower half of the base portion 51 of the housing 5 has an opening as wide as possible at a position corresponding to the outer periphery of the fan 9, forms an exhaust port 16, and further extends a part of the tip portion to extend the leg. The ventilation unit 1 is configured as the unit 17.
[0039]
In the ventilation unit 1 having such a configuration, when the motor 6 supplied with electric power from the battery 7 rotates, the fan 9 fixed to the rotating shaft 61 of the motor 6 starts rotating. As the fan 9 rotates, the air that has flowed in through the inlet 15 is sent out through the outlet 16. At this time, if the gap between the casing 11 and the fan 9 is too large, there is no danger of the two hitting or rubbing, but a so-called short circuit in which part of the air sent to the exhaust port 16 returns to the opening 10. And reduce the performance of ventilation. In order to avoid this adverse effect, the present invention uses a labyrinth structure as well as narrowing the gap as much as possible to reduce the short circuit and maintain the ventilation performance, so efficient ventilation is realized. You.
[0040]
On the other hand, as shown in FIG. 2, the whole or a part of the container main body 40 whose upper surface is open is formed of a transparent or translucent resin, and the upper end of the container unit 4 is formed in a flat flange shape. An upper edge 41 is formed, and the upper edge 41 is hermetically sealed by an appropriate method such as welding or bonding using a liquid leakage prevention means 42 formed of a gas-permeable / water-impermeable sheet.
[0041]
A partition 43 made of resin is provided inside the container body 40, and an upper edge portion formed into a flange shape like the container body 40 is hooked and stopped by a projection 44 on a side surface of the container body 40. ing. A deliquescent granular hygroscopic agent 45 such as calcium chloride, magnesium chloride, phosphorus pentoxide or the like is stored in the partition 43 in advance, and is held in the middle stage of the container body 40. Holes or groove-shaped dropping windows 46 are opened on the bottom and side surfaces of the partition 43, and the container unit 4 that stores the deliquescent liquid 47 smoothly in the storage chamber 48 is configured.
[0042]
In the container unit 4 having such a configuration, the liquid leakage prevention means 42 that covers the open upper surface is made of a gas-permeable and water-impermeable sheet. Inflows easily. The inside contains a so-called deliquescent absorbent 45, such as calcium chloride, magnesium chloride, phosphorus pentoxide, etc., which absorbs moisture in the air and liquefies itself, so that the inflowing air is removed of moisture and leaked again. It goes out through the liquid prevention means 42. In other words, it functions as a so-called natural ventilation type dehumidifier for dehumidifying the air in a clothes chest or a clog box.
[0043]
As shown in FIG. 3, the relationship between the ventilation unit 1 and the container unit 4 is such that the ventilation unit 1 is detachably provided at the upper end of the container unit 4. Is placed on the upper edge 41 of the container unit 4 and is removably fixed by an appropriate method such as using the band 2, and the bell mouth-shaped suction port 14 of the ventilation unit 1 covers the ceiling surface of the container unit 4. Although it is in contact with the prevention means 42, it becomes a dehumidifier that is used by hanging it on a clothes closet or placing the container unit 4 as it is on a shelf of a clog box in the state of FIG.
[0044]
That is, when the ventilation unit 1 is driven, the air in the container unit 4 is sucked from the suction port 14 through the liquid leakage prevention means 42, so that the air in the container unit 4 becomes lean, and Ambient air flows in through the portion where 14 is not in contact. That is, it functions as a forced ventilation type dehumidifier.
[0045]
FIG. 4 shows a second embodiment, in which a bell mouth-shaped suction port 14 connected to the connection port 12 of the ventilation unit 1 shown in FIG. 1 is replaced with a flexible pipe 3 made of a flexible pipe or hose. This shows a situation in which the suction port 14 is connected to the distal end of the flexible tube 3 and is brought into contact with the liquid leakage prevention means 42 of the container unit 4 to be used as the dehumidifier of the present invention. Unlike the previous example, the suspension device 8 is hung on a clothes closet or the like, but the container unit 4 is placed on the floor or a shelf, and becomes a dehumidifier that can use the two units separately.
[0046]
In the case of the dehumidifier that functions separately as in the present embodiment, unlike the first embodiment, even if a pushing force is applied, the dehumidifier is suspended by the suspension tool 8 of the ventilation unit 1. It is hard to fall down. In addition, because it accommodates functional parts such as motors, fans, and batteries, it can be made smaller and has a greater degree of freedom with respect to the floor than a forced-ventilation type dehumidifier, which had to be enlarged. It also increases.
[0047]
FIG. 5 shows a third embodiment of the present invention. The difference from the first embodiment shown in FIG. 2 is that instead of the liquid leakage preventing means 42, the outer liquid leakage preventing means 21 made of a gas-permeable and water-impermeable sheet having a round hole at the center is hermetically sealed. In place of the flat partition 43, the central portion is raised up to the sheet surface in a chimney shape to form a ventilation pipe 20, and the lower end face of the ventilation pipe 20 is formed with an inner leaking surface made of a circular air-permeable and water-impermeable sheet. It was hermetically sealed with the liquid prevention means 22. With such a configuration, a dehumidifier is used in which the distal end of the flexible tube 3 made of a flexible pipe or hose is directly inserted into the container unit 4 and used.
[0048]
According to such a configuration, the air in the container unit 4 is sucked by the ventilation unit 1, passes through the inner liquid leakage prevention means 22, and is discharged from the exhaust port 16 via the flexible pipe 3, but at the same time, the outer leakage is prevented. It acts so that the surrounding air flows in through the liquid prevention means 21. At this time, as is clear from the figure, the air flows so as to lick the outer periphery of the partition 43 and the surface of the moisture absorbent 45, and is sucked from the distal end of the flexible tube 3. This clearly indicates that the moisture absorption is performed more efficiently than in the first and second embodiments.
[0049]
FIG. 6 shows a fourth embodiment. In each of the above embodiments, the ventilation unit 1 can be used repeatedly and the container unit 4 is disposable, but in this embodiment, the container unit 60 is also used repeatedly. Is possible.
[0050]
That is, the container unit 60 has a large opening 62 having a threaded portion and a relatively small-diameter hose, such as a wide-mouth bottle in which the container main body 61 is manufactured by blow molding of transparent or translucent resin or glass. A hollow body having an insertion port 63, a check valve 64 made of a flexible material having a large repulsive force such as rubber is provided inside the insertion port 63. The check valve 64 does not use the repulsive force of a material such as rubber, but can provide the same operation and effect even when the repulsive force is urged by, for example, a spring means.
[0051]
The lid 65 made of resin screwed into the opening 62 has a large opening at the center of the upper surface, and the opening is coated with an adhesive from the back surface of the lid 65 to the periphery made of a gas-permeable / water-impermeable sheet. The upper surface liquid leakage prevention means 66 is attached and closed. The resin partition 43 is wrapped around the entire periphery of the upper edge formed into a flange shape with a packing 67, and is sandwiched between the edge of the opening 62 and the lid 65 to which the upper surface liquid leakage prevention means 66 is attached. , And the moisture absorbent 45 is held in the middle stage to constitute a reusable container unit 60. It goes without saying that the ventilation unit 1 is the same as that described with reference to FIGS. 3 and 4, and functions in combination as a dehumidifier.
[0052]
In the dehumidifier having such a structure, the lid 65 is opened, the hygroscopic agent 45 is stored in the partition 43 in an appropriate amount, and the lid 65 is closed. Then, the distal end of the flexible tube 3 is inserted into the insertion port 63. At this time, the check valve 64, which has sealed the container, is pushed open, and the outlet of the internal air is secured. When the ventilation unit 1 is operated to suck air in the container, efficient moisture absorption is performed as in the embodiment shown in FIG. When the hygroscopic agent 45 almost deliquesces and the deliquescent liquid accumulates, the flexible tube 3 is withdrawn, the lid 65 is opened, the partition 43 is taken out, and the deliquescent liquid is discarded. After that, a new use is started by replenishing a new moisture absorbent 45.
[0053]
Thus, a reusable container unit 60 that can be used repeatedly can be provided.
[0054]
In this embodiment, since the ventilation unit 1 is firmly held by the suspension device 8, there is no danger of overturning. If the repetitive use container unit 60 overturns over, the flexible tube 3 falls out. Immediately, the check valve 64 closes the insertion port 63 with a repulsive force to prevent the deliquescent liquid from flowing out.
[0055]
Moreover, since the liquid leakage is prevented by the packing 67 at the screwed portion between the container body 61 and the lid 65, even if it falls down, the liquid does not leak from the screwed portion.
[0056]
The upper surface of the lid 65 serving as an air inlet does not leak because the upper surface liquid leakage prevention means 66 prevents liquid leakage. Because it is made of a non-woven sheet, it is expected that dust will cause clogging during long use. In such a case, the upper surface liquid leakage prevention means 66 attached with the adhesive may be peeled off and replaced with a new upper surface liquid leakage prevention means 66. It does not hinder.
[0057]
In each of the above embodiments, the description has been made in which the ventilation unit sucks the air inside the container unit. However, even if the air flow is completely reversed by replacing the intake air and the exhaust air, the invention does not depart from the gist of the present invention. Absent.
[0058]
Furthermore, the present invention relates to a dehumidifier using a hygroscopic agent. However, the present invention can be applied to, for example, a deodorizer using a deodorant, an aroma device using an aromatic agent, and a insect trap using an insecticide.
[0059]
【The invention's effect】
As described above, according to the dehumidifier of the present invention, the advantages of each of the natural ventilation type and the forced ventilation type are adopted, so that the dehumidifier is excellent in dehumidification ability, and can be realized at low cost and small size and light weight. Further, it is easy to maintain and highly versatile.
