Abstract

PURPOSE:To remarkably enhance dehumidification efficiency by providing an air hole to the vessel of a dehumidifier and forcibly introducing the outside air into the vessel and efficiently bringing large amounts of air into contact with a desiccant. CONSTITUTION:When a fan 10 is rotated, the wet air of the outside of a vessel 1 is passed through a suction pipe 8a from a suction hole 8 and introduced into the vessel 1. This wet air is once introduced into a deliquescent liquid storage chamber 1a and thereafter passed through an annular gap 22 between the suction pipe 8a and a desiccant housing vessel 5. In this case, this air is passed through the fine holes 5d of the vessel 5 and brought into contact with a desiccant 6. Water is absorbed by the deliquescent action and the wet air is made dry air. This dry air is pushed out by fresh air introduced through the suction hole 8 and reaches the space 23 in a cover and discharged to the outside of the vessel 1 through an exhaust hole 14. The larger amounts of air are brought into contact with the desiccant 6 by the fan 10 and the air holes are separated into the suction hole 8 and the exhaust hole 14. Thereby a series of flow path is formed wherein the air is introduced and thereafter discharged and therefore the wet air can be efficiently brought into contact with the desiccant 6.

can be stored in

[Problem to be solved by the invention]

However, in such conventional dehumidifiers, the movement of air flowing into the container 1 and the movement of air flowing out from the container 1 are caused by natural convection, so that the deliquescent desiccant 3
The disadvantage is that the amount of air that comes into contact with the air is limited, and the dehumidification effect is also limited.

Therefore, this invention was made in consideration of these points, and the purpose of this invention is to provide a structure in which air from outside the container is forcibly taken into the inside of the container and a larger amount of air is brought into contact with the desiccant. Another object of the present invention is to provide a dehumidifier that uses a deliquescent desiccant and has a high dehumidification effect.

[Means to solve the problem]

The present invention provides a dehumidifier using a deliquescent desiccant in which a deliquescent desiccant is contained in a container provided with a deliquescent liquid storage chamber, and a vent hole is provided in the container to communicate between the inside and the outside. The above-mentioned problem is solved by configuring a dehumidifier using a deliquescent desiccant in which the ventilation hole is provided with a blower device that takes air from outside the container into the container.

Further, it is preferable that the air blowing device is a dehumidifier using a deliquescent desiccant, which is connected to a control device that turns on and off the air blowing function in accordance with the water level of the deliquescent liquid in the deliquescent liquid storage chamber.

In addition, the control B device may be configured by a float disposed in the storage chamber and a clutch interlocked with the movement of the float, which is provided between the motor and the fan of the blower. .

Further, the control device includes a float disposed in the storage chamber, and a switch provided in wiring between the motor and battery of the blower device that is linked to movement of the float.
It may also be configured by

Furthermore, the blower may include a centrifugal fan provided on the discharge side of the ventilation hole.

[Effect]

When the blower device located in the vent of the container is activated, humid air outside the container is introduced into the interior of the container through the vent. This humid air comes into contact with the desiccant contained in the container, and the moisture is adsorbed by the desiccant to become dry air, which is then discharged to the outside of the container again. In particular, in the dehumidifier of the present invention, since humid air outside the container is sequentially introduced into the container by the blower, a large amount of air can be efficiently (dried). The deliquescent water becomes deliquescent liquid, drips from the desiccant storage container of the desiccant, and is stored in the deliquescent liquid storage chamber.

In particular, in the dehumidifier of claim (2), when the deliquescent liquid in the deliquescent liquid storage chamber reaches a predetermined water level, the control device automatically stops the fan of the blower, and fresh air from the outside is removed. is no longer introduced into the container, and moist air no longer comes into contact with the desiccant. Therefore, the deliquescent liquid in the storage chamber does not increase, and the rise in the water level in the storage chamber almost stops. In addition,
When the deliquescent liquid is drained to lower the water level in the deliquescent liquid storage chamber below a predetermined water level, the fan automatically restarts.

Moreover, in the dehumidifier of claim (3), when the water level in the deliquescent liquid storage chamber increases, the float disposed inside the dehumidifier rises. Then, when the float rises to a predetermined height,
Disengage the clutch located between the blower motor and fan to stop the fan.

Furthermore, in the dehumidifier of claim (4), the float rises as the water level in the deliquescent liquid storage chamber increases, and when this float reaches a predetermined height, the wiring between the motor and the battery that drives it rises. Turn off the switch installed in
Stop the blower itself.

In the dehumidifiers of claims (3) and (4), once the deliquescent liquid in the deliquescent liquid storage chamber is drained, the float descends under its own weight and the blower is started again.

Furthermore, in the dehumidifier according to claim (5), the centrifugal fan forms a ventilation path that sucks external air from the inside of the container, that is, from the desiccant side and circulates it to the fan side. Even when a wet membrane is used to prevent the desiccant from overflowing, external air can be brought into direct contact with the desiccant through the moisture-permeable membrane, and a higher adsorption effect can be obtained.

〔Example〕

(First Embodiment) A first embodiment of the present invention will be described based on FIGS. 1 to 4.

FIG. 1 shows a side sectional view of a dehumidifier according to a first embodiment.

The container 1 consists of a main body 2, which is a cylindrical container that opens at the top, and a lid 3 that covers the opening 2C, both of which are made of synthetic resin.

A deliquescent liquid storage chamber 1a is formed in the inner bottom of the main body 2. Inside this storage chamber 1a, a float 4 having a float 4b at the tip of an arm 4a extending radially is arranged, and a pin formed at the apex of the base 2a at the bottom of the main body 2 is placed in a concave part of the center part 4C. 2b is fitted into the main body 2 so that the float 4 can move up and down.

An annular desiccant storage container 5 having a central hole 5c is disposed above the main body 2, and this storage container 5 has a flange 5b formed on the periphery of the upper surface of the container 5, which is connected to the opening 2c of the main body 2. It is fixed on the rim of the mouth. The storage container 5 has a deliquescent desiccant 3 such as calcium chloride or magnesium chloride sealed therein, and has a deliquescent liquid dripping hole 5a on its lower surface for draining the deliquescent liquid 21. Moreover, a small hole 5d for the purpose of ventilation is provided on the upper surface and the inner circumferential surface of the central hole 5c. Note that the deliquescent agent storage container 5 is composed of a net, and the net is connected to these deliquescent liquid dripping holes 5a.
It can also be used as .

The lid 3 is a bowl-shaped body opening downward, and is screwed onto the main body 2 so as to cover the opening 2C above the main body 2.

This lid body 3 is provided with a vent hole that communicates between the inside and outside of the container l, and this vent hole includes an intake hole 8 that introduces air into the inside of the container l, and an air intake hole 8 that exhausts the air inside the container 1. and an exhaust hole 14. The air intake hole 8 is defined by an air intake pipe 8 a that is a tubular body formed integrally with the lid 3 at the center of the lid 3 . Since this intake pipe 8a has an outer diameter smaller than the inner diameter of the center hole 5c of the desiccant storage container 5,
As shown in FIG. 1, when the lid 3 is screwed onto the main body 2, an annular gap 22 is formed between the center hole 5c and the intake pipe 8a.

A plurality of exhaust holes 14 are provided so as to surround the intake hole 8, and the battery 12 is housed in the lid space 23 between the lid 3 and the desiccant storage container 5.

A motor 9 is supported inside the intake pipe 8a, and a fan 1O and the like that engage with the motor 9 are arranged, and the structure of this part is shown separately in FIGS. 2 and 3.

The blower A is a device that forcibly introduces air outside the container 1 into the container 1, and includes a motor 9. Fan 10. It is constituted by a battery 8. Further, the control device B controls the blowing function of the blower B according to the water level of the deliquescent liquid storage chamber 1a.
4. An automatic disconnection device comprising a float 4. Clutch 11. It is composed of an actuating rod 33 and a weight 34.

An upper member 11a of a clutch 11 is engaged with the rotating shaft of the motor 9, and a lower member 11b, which is paired with the upper member 11a, has blades 10a integrally formed on its outer periphery to act as a fan. It is 10. Furthermore, the lower member 11b of this clutch 11 has an operating rod 3 at its lower part.
3 is suspended, and a weight 34 is attached to the lower end of the operating rod 33.
is fixed. Directly below this actuating rod 33, the center portion 4C of the float 4 described above is placed at a predetermined interval.
will be located.

The upper member 11a of the clutch 11 is a cylindrical body, and the lower member llb is a cylindrical body having a larger inner diameter.
It is loosely fitted so that it can move up and down within a certain width.

In addition, the lower end of the outer peripheral surface of the upper member 11a and the lower end of the outer peripheral surface of the lower member 1
Teeth that mesh with each other are formed on the upper end of the inner circumferential surface of 1b. That is, when the clutch 11 is extended, the teeth mesh with each other and the two are coupled in the shaft rotation direction, whereas when the clutch 11 is shortened,
The structure is such that when the meshing of both tooth bodies is released, this connection is also released. Note that an annular disc 35 is adhered to the upper end surface of the lower member 11b to serve as a material to prevent the upper member 11a from being removed. FIG. 3 shows the structure of this clutch in a shortened state.

Next, the operation of this embodiment will be explained.

When a switch (not shown) is turned on to start the motor 9 and rotate the fan 10, moist air outside the container 1 is introduced into the container 1 through the intake hole 8 and the intake pipe 8a. This air first enters the deliquescent liquid storage chamber 1a, and then passes through the annular gap 22 between the intake pipe 8a and the desiccant container 5. At this time, this air enters the desiccant container 1a. It passes through the pores 5d of 5 and comes into contact with the desiccant 6, and its deliquescent action absorbs moisture, resulting in dry air.

Then, this air is pushed out by new air introduced from the intake hole 8, reaches the lid space 23, and further passes through the exhaust hole 14, which is a ventilation hole, and is discharged to the outside of the container l.

That is, the air flows through the intake holes 8. as shown by the arrows in FIG. Deliquescent liquid storage chamber 1a, annular gap 22. Lid interior space 23.
The moisture of the humid air flowing through the exhaust hole 14 is sequentially adsorbed by the action of the desiccant 6, becoming dry air and being discharged to the outside of the container 1.

On the other hand, the moisture absorbed by the desiccant 6 becomes a deliquescent liquid 21 in which the desiccant 6 is dissolved, drips from the deliquescent liquid dripping hole 5a, and is stored in the deliquescent liquid storage chamber 1a.

When the water level in the storage chamber 1a gradually rises, the water level in the storage chamber 1a
The float 4 disposed inside rises.

When this float 4 reaches a predetermined height, its center 4
c contacts the weight 34 at the lower end of the actuating rod 33, and further pushes the actuating rod 33 upward as the water level rises.

As shown in FIG. 2, in a normal state, the clutch 11 is expanded by the weight of the lower member 11b and the loads of the actuating rod 33 and the weight 34, and is in a connected state. but,
When the actuating rod 33 rises, as shown in FIG. 3, the lower member 11b of the clutch 11 on which it is suspended also rises, and the teeth of this tooth and the upper member 11a are disengaged. As a result, the clutch 11 is disengaged. That is, the motor 9 idles, the fan 10 stops rotating, and new air from outside the container 1 is no longer introduced, so the rise in the water level in the deliquescent liquid storage chamber 1a also stops.
The deliquescent liquid 21 will not overflow from the container 1.Furthermore, by setting the actuation point of the clutch 11 to an appropriate water level, it is possible to avoid a large amount of deliquescent liquid 21 from accumulating in the storage chamber 1a. Even if the container is tipped over, it is possible to prevent an accident in which the deliquescent liquid 21 flows out of the container 1 and contaminates the place where the dehumidifier is installed.

Note that if the lid 3 of the container l and the desiccant storage container 5 are removed from the main body 2, the deliquescent liquid 21 is drained, and then reassembled,
The float 4 is lowered again, the clutch 11 is connected, and the fan IO starts rotating.

As described above, depending on the dehumidifier of this embodiment, not only can a larger amount of air be brought into contact with the desiccant 6 by the function of the air blower A, but also the ventilation hole can be connected to the intake hole 8 and the exhaust hole. Divide into 14 parts, take outside air into the container l,
Since a series of flow paths are formed until the air is discharged, moist air can be brought into contact with the desiccant 6 more efficiently.

Furthermore, in this embodiment, even if the fan 10 stops rotating, the motor 9 continues to rotate, so the deliquescent liquid 21 evaporated from the deliquescent liquid storage chamber 1a recrystallizes and adheres to its rotating shaft. It is possible to prevent the shaft from solidifying.

Note that FIG. 4 shows another structure of the clutch 11.

The second clutch 11 includes a conical clutch lower member 11b fixed to the rotating shaft of the motor 9, and a blade 10a on the outer peripheral surface.
It consists of a clutch upper member 11a that forms a fan 10 and a push-up member tic that presses the upper member 11a upward in conjunction with the float 4.

The clutch lower member 11b is a conical body tapered upward to a smaller diameter, and has a flange lid at the bottom, and a plurality of pins protruding from the upper surface of the flange lid. The clutch upper member 11a is an annular body having an opening in the center and having an outer diameter larger than the flange lid, and the lower surface of the clutch upper member 11a has a small opening into which the pin of the lower member 11b is fitted. A hole is opened in this lower member 11b.
is passed through this opening, and the flange l of the lower member 11b
When placed on the id, the two are engaged. The push-up member 11c is a cylindrical body, and the clutch lower member 11b
A structure in which the lower end is fitted so as to be movable up and down with a certain width, and when the pin is moved up to the maximum, the upper end comes into contact with the lower surface of the clutch upper member 11a and releases the engagement between the pin and the small hole. It becomes. Note that an operating rod 33 with a weight 34 fixed to the lower end is suspended from the lower part of the push-up member 11c, and the push-up member 11c is placed at a predetermined position in the intake pipe 8a. It is positioned movably up and down by a support member 38 extending from the inner surface of 8a.

In this clutch 11, like the clutch 11 described above, not only can the clutch 11 be connected and disconnected in conjunction with the movement of the float 4, but also the clutch lower member 1
Since 1b is constructed of a conical body, if the container 1 falls, the upper member 11a will slide off the flange lid of the lower member 11b due to the impact and the wind pressure of the fan 10, and the connection between the two will be easily broken. .

Therefore, with this clutch 11, even if the container 1 falls, the clutch 11 will be disconnected, so the amount of deliquescent liquid 21 will not increase in the fallen state, and the deliquescent liquid 21 will be removed from the fallen container 1. Accidents in which the liquid 21 continues to flow out can be prevented.

(Second example) A second embodiment of the present invention will be described based on FIG.

FIG. 5 is a side sectional view of the second embodiment.

In this embodiment, instead of the clutch 11 of the first embodiment,
A switch 13 that connects and disconnects the wiring between the motor 9 and the battery 12 is arranged inside the intake pipe 8a. That is, in this embodiment, the control device B controls the float 4. Switch 13. It is composed of an operating rod 33 and a weight 34.

The switch 13 includes a contact piece 13a fixed to the upper end of the actuation rod 33, and a support piece 13b disposed below the contact piece 13a and supporting the actuation rod 33 in the intake pipe 8a through the contact piece 13a. Metal pieces are adhered to the contact surfaces of both, and wiring 36 led out from the battery 12 and the motor 9 is brought into contact with both metal pieces, respectively.

The other structure is the same as that of the first embodiment.

In this embodiment, under normal conditions, the contact piece 13a contacts the support piece 13b due to the load of the actuating rod 33 and the weight 34, and the switch 13 is turned on, causing the motor 9
Rotate to continue drawing air from the outside of container 1.

However, when the float 4 rises due to the rise in the water level in the deliquescent liquid storage chamber 1a and pushes up the actuating rod 33, the contact piece 13a
The support piece 13b is separated and the switch 13 is turned off, thereby stopping the rotation of the motor 9.

Therefore, new moist air is no longer introduced from outside the container 1, and the water level in the deliquescent liquid storage chamber 1a stops rising.

In this embodiment, since the rotation of the motor 9 itself is stopped when the water level rises, an economical dehumidifier that suppresses the consumption of the battery 12 can be constructed.

Other operations and effects are the same as those in the first embodiment, and will therefore be omitted.

In addition, 1. In both the second embodiment, an exhaust hole 14 is provided on the top surface of the container 1, and as shown in FIG.
4 facing downward on the side of the container l, it is possible to prevent the exhausted dry air from being sucked in again and deteriorating the dehumidification efficiency.

Further, as shown in the figure, an aromatic agent 25 is provided in the lid inner space 23.
If installed, this dehumidifier can also be used as an air freshener spraying device.

Furthermore, if a deliquescent liquid discharge hole is provided at the bottom of the main body 2 of the container 1, and the structure is such that it can be opened and closed with a plug, the deliquescent liquid 21 can be drained without disassembling the container 1, making the work easier. can.

(Third Embodiment) Next, a third embodiment of the present invention will be described based on FIGS. 7 and 8. Here, the same reference numerals are used for the same components as in each of the embodiments described above, and the description thereof will be omitted or simplified.

In these figures, 40 indicates a rectangular parallelepiped container of the dehumidifier. This container 40 has a container main body 42 that opens upward.
and a lid body 44 that can be detachably attached to the opening of the container body 42.

A desiccant storage container 46 with an open top is inserted into the container main body 42. Specifically, a flange 46a extending outward from the upper peripheral edge of the storage container 46 is inserted into the inner upper part of the container main body 42. The container 46 can be detachably inserted by placing it on a shoulder 42a formed on the periphery. Since the height of the container 46 is smaller than the height of the container body 42, the remaining space on the bottom side of the container body 42 becomes a deliquescent liquid storage chamber 42b.

A plurality of deliquescent liquid dripping holes 46b are formed in the bottom surface of the storage container 46. Further, after putting the desiccant 6 into the storage container 46, a moisture permeable membrane 48 is attached using the upper surface of the flange 46a to seal the storage container 46 and prevent the desiccant 6 from overflowing. .

Furthermore, a fan housing 52 protruding from one side of the center of the upper surface of the lid body 44 houses a multi-blade fan (also referred to as a sirocco fan) 50 as a centrifugal fan having forward-facing blades, and has a vortex chamber. A motor housing 5 that accommodates a DC motor 54 is provided on the upper surface of this housing 52.
6 is further provided protrudingly. The DC motor 54 is fixed to the housing 56 with its rotation axis facing downward, and
Its rotating shaft is connected to the rotating shaft of the multi-blade fan 50 within the fan housing 52, so that the multi-blade fan 50 rotates in a plane parallel to the lid 44 as the motor 54 rotates. As shown in the figure, a plurality of exhaust slits 52a are bored in one side of the fan housing 52 in an aligned manner.

A battery case 60 that removably accommodates a battery 58 is attached to a position adjacent to the fan housing 52 at the center of the top surface of the lid 44, and power from the battery 58 is supplied to the motor 54. There is. In this embodiment, a multi-blade fan 50° motor 54 and a battery 58 constitute the essential parts of the blower.

Furthermore, the lid body 44 includes a plurality of intake slits 44a formed on both sides of the fan housing 52 and the battery case 60 as shown in the drawing. Here, the intake slit 44a.

. . , 44a into the container and then discharged through the aforementioned exhaust slits 52a, . . . , 52a, forming a ventilation hole.

Next, the effects of the third embodiment will be explained.

First, the desiccant storage container 46 is inserted into the container body 42 and the battery 5 is placed in the battery case 60 with the lid 44 covered.
When the fan 8 is inserted, the motor 54 rotates, and the multi-blade fan 50 is energized by the motor 54 and rotates in a predetermined direction. This allows the air outside the dehumidifier to flow through the intake slits 44a on both sides.
, 44a, permeates through the moisture permeable membrane 48, and enters the storage container 46.
(see the arrows in Figures 7 and 8), this sucked air comes in contact with the desiccant 6, and is again permeated by the suction force of the multi-blade fan 50, as shown by the arrow in Figure 8. It passes through the membrane 48 and is sucked into the fan 50, after which,
As shown in FIG. 7, the exhaust gas is discharged to the outside through the vortex chamber of the housing 52 from the exhaust gas 52a, . . . , 52a.

That is, by using the multi-blade fan 50, external air can be sucked from inside the container, and the air flow toward the permeable membrane 48 can be rectified vertically or nearly vertically. This forced circulation of air allows for warmer and more efficient air circulation compared to conventional structures in which air circulation into the dehumidifier was insufficient with only natural convection due to the low air permeability of the permeable membrane 48. It can be circulated. During the circulation, water is absorbed by the deliquescent action as in each of the above-mentioned examples.
This moisture becomes the deliquescent liquid 21, and the deliquescent liquid dripping hole 46b,
..., 46b, and is stored in the deliquescent liquid storage chamber 42b. In this way, even if the outside air is humid, contact with the desiccant 6 increases, so the moisture absorption effect is enhanced, and accordingly, high moisture-proofing, mold-proofing, and deodorizing effects can be obtained.

On the other hand, the operation can be stopped by removing the battery 58 from the case 60, and the deliquescent liquid 21 accumulated in the storage chamber 42b can be easily disposed of by removing the container 46 after removing the lid 44. Furthermore, when the desiccant 6 is exhausted, it can be used repeatedly by completely replacing the desiccant container 46.

Further, according to the ventilation hole of the third embodiment, the external air once passes through the deliquescent liquid storage chamber as in the first and second embodiments,
Thereafter, unlike contacting the desiccant 6 through pores, the external air is circulated directly through the moisture permeable membrane 48 into the chamber containing the desiccant 6, so that the moisture in the external air is further absorbed in the storage chamber. There is also the advantage that there is no increase in humidity, and therefore, dehumidification can be performed more efficiently.

Note that the centrifugal fan in the invention set forth in claim (5) is not limited to the multi-blade fan shown in the third embodiment, but may also be a backward-facing blade fan or a radial fan, for example.

〔Effect of the invention〕

As explained above, according to the dehumidifier of the present invention, by forcibly drawing air from outside the container into the inside of the container, a large amount of air can be efficiently brought into contact with the desiccant, thereby improving the dehumidification effect. can be dramatically improved.

In addition, in the dehumidifier of claim (2), even if the deliquescent liquid increases rapidly and the water level in the deliquescent liquid storage chamber 1a rises, the blowing device is automatically turned off once the water level rises to a predetermined height. Since the deliquescent liquid is stopped and the increase in the deliquescent liquid is stopped, it is possible to prevent the deliquescent liquid from overflowing from the container. Furthermore, by setting the operating point of the control device at a predetermined water level, it is possible to prevent the deliquescent liquid from flowing out even if the container is tipped over, thereby preventing the installation site from being contaminated.

In particular, in the dehumidifier of claim (3), even if the blower function of the blower is stopped, the power unit continues to operate.
It is possible to prevent the harmful effect that the evaporated deliquescent liquid recrystallizes and adheres to the rotating shaft of the power plant, thereby hindering the restart of the power plant.

Further, in the dehumidifier of claim (4), when the blowing function of the blower is stopped, the rotation of the power unit itself is stopped, so that it is possible to prevent unnecessary consumption of battery power. .

Furthermore, in the dehumidifier according to claim (5), since the centrifugal fan can form a ventilation path in the direction of sucking external air from the inside of the container and circulating it to the fan side, for example, a moisture permeable membrane can be used. Even with a structure in which the desiccant is isolated, external air can be efficiently sucked through the moisture-permeable membrane and brought into contact with the desiccant, which has the effect of achieving more efficient dehumidification.
