Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hygroscopic device, and more particularly to a technique for efficiently drying and regenerating the hygroscopic agent inside the hygroscopic cartridge regardless of the number of hygroscopic cartridges.

[0002]

2. Description of the Related Art Conventional moisture absorbers use a Peltier device that uses a Peltier element to condense moisture in the air to absorb moisture as water, or a moisture absorber such as calcium chloride that reacts with moisture in the air. For example, if the hygroscopic agent is disposable, the amount of hygroscopicity is represented by the water stored. However, this product has a drawback that water will spill when it falls. Therefore, in Japanese Patent Application No. 2-73817, we have proposed a hygroscopic device which can be used by regenerating the hygroscopic agent with good usability in a small space.

However, such a Japanese Patent Application No. 2-7381
In No. 7, although it is for a small space, a hygroscopic agent and a heater for regeneration are built in the main body, and it takes a certain amount of space to incorporate these, so there is a problem that it cannot be used in an extremely small space. there were. Further, when the capacity of the hygroscopic agent is full, it has to be dried and regenerated over a predetermined time, so that there is a problem that moisture cannot be absorbed during that time.

Therefore, we have filed Japanese Patent Application No. 3-121609.
No. 3, a cartridge having a flat shape and having vent holes on both sides, a drying unit having a heater, and a blower unit having a blower, and the cartridge is attached to and detached from the drying unit and the blower unit at a side face having the vent hole. We are proposing a cartridge system that can be made freely.

[0005]

However, in the above-described moisture absorber, the rotation speed of the blower of the drying unit is constant regardless of the number of moisture absorption cartridges,
Therefore, the maximum number of moisture absorption cartridges (for example, 4)
When piled up, the air resistance is maximized, the wind passing through the heater unit built into the drying unit is reduced, the wind speed is reduced, and the temperature is maximized. When the number of moisture absorption cartridges decreases, the air resistance decreases, the amount of wind passing through the heater increases, the wind speed increases, and the temperature decreases. Then, the temperature at which the hygroscopic agent is dried and regenerated becomes low, and the time required for regeneration becomes long. For example, if it takes 6 hours to reproduce four sheets, there is a problem that two sheets take about four and a half hours instead of three hours, which is half the time.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a hygroscopic device having a drying unit that does not reduce the efficiency of dry regeneration even when the number of dried hygroscopic cartridges decreases. To try to serve.

[0007]

The moisture absorber of the present invention incorporates a moisture absorbing cartridge 7 which is flat and has ventilation holes 6 formed on both sides thereof and a moisture absorbing material 9 accommodated therein, a blower 1 and a heater 30. The drying unit 31 is provided, and the moisture absorption cartridge 7 is detachably attached to the drying unit 31, and the moisture absorption cartridges 7 are configured to be connectable so that the ventilation holes 6 communicate with each other. The number of rotations is changed as the number of the moisture absorption cartridges 7 mounted on the drying unit 31 decreases, and the number of rotations changing means C is provided.

[0008]

When the number of the moisture absorption cartridges 7 mounted on the drying unit 31 is small, the rotation speed changing means C reduces the rotation speed of the blower 1 to reduce the air volume passing through the heater 30 and increase the air volume. Therefore, it is possible to avoid the temperature of the introduced air from being raised to a proper temperature, and to regenerate and dry a small number of the moisture absorption cartridges 7 in a high temperature state. When the ventilation holes 6 of the moisture absorption cartridge 7 are aligned and a plurality of sheets are stacked and mounted on the drying unit 31, the rotation speed of the blower 1 of the drying unit 31 is increased, and a large amount is obtained regardless of the air resistance when a large number of sheets are stacked. Hot air is sent, and re-drying is performed with warm air heated to an appropriate temperature without causing a shortage of air volume.

[0009]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 2 shows a cartridge 7 filled with a hygroscopic agent 9. In the moisture absorption cartridge 7, the moisture absorbent 9 is loaded in the housing 8 having the ventilation holes 6 formed on both sides, and the slide convex portion 10 is formed on the edge portion on one side of the housing 8.
A slide concave portion 11 is formed on the edge portion on the other surface side, and the slide convex portion 10 and the slide concave portion 11 are slidably fitted together to adjust the number of cartridges 7 to be combined and slide fitted into the drying unit 31. It can be installed by doing so.

FIG. 1 shows a state in which the moisture absorption cartridge 7 is assembled to the drying unit 31. Drying unit 31
The fan 34 as the blower 1 and the heater holding frame 29
The heater 30 held by is provided. The fan 34 is driven by the motor 33 built in the case 32 of the drying unit 31, and the air sucked from the suction port 35 is supplied to the heater holding frame 2.
The heater 30 held at 9 raises the temperature to collect warm air in the warm air reservoir 36, and such warm air can be ejected from the ejection port 37. Reference numeral 38 is a switch, and the spout 3
7 is separated from the heater 30 side by an intake path by the intake port 35, and the outside air drawn from the intake port 35 is switched to the switch 3
The temperature of the switch 38 is suppressed by passing through the vicinity of 8 parts,
The influence of warm air from the ejection port 37 is avoided. Fitting protrusions (not shown) having the same shape as the slide protrusions 10 are formed on both edges of the surface of the drying unit 31 on which the moisture absorbing cartridge 7 is mounted. Then, the slide recess 11 of the moisture absorption cartridge 7 is fitted to the fitting protrusion.
Is slidably fitted, the cartridge 7 is set in the drying unit 31, and the hygroscopic agent 9 in the cartridge 7 is dried by hot air from the drying unit 31 to be regenerated.

As shown in FIG. 2, a click-locking convex portion 26 is formed at the approximate center of one surface of the moisture absorbing cartridge 7. A concave groove 22 is formed on the other surface of the moisture absorbent cartridge 7, and the click locking portion 23 is elastically displaceable by a pair of notches 27 at the center of the concave groove 22 in the length direction.
A concave portion 23a is formed in the concave portion 23a, and the click locking convex portion 26 is inserted into the concave portion 23a of the click locking portion 23 so that the moisture absorbing cartridges 7 can be connected with a feeling of moderation by the click operation. In such a case, the ventilation holes 6 of the moisture absorption cartridge 7 are communicated with each other through the air passage X. The peripheral portion of the air passage X is surrounded by the ribs 24 so as to prevent the blown air from escaping to the outside.

According to this structure, the temperature of the air sucked from the suction port 35 by the drive of the fan 34 is raised by the heater 30, and the hot air trap 36 is blown out from a large number of jet ports 37. Then, the hygroscopic agent 9 is dried with warm air through the vent holes 6 of the moisture absorbing cartridge 7, and the moisture absorbing cartridge 7 overlaid thereon is similarly dried for regeneration. FIG. 3 is a circuit diagram showing the rotation speed changing means C. The resistances R _{1 to} R ₄ are switched by switching the terminals of the switch S to the terminals S _{1 to} S ₄ so that the rotation speed of the motor 33 is changed. I am doing it. That is, the switch S is switched to the terminal S ₄ side so that the rotation speed of the blower 1 decreases as the number of the moisture absorption cartridges 7 mounted on the drying unit 31 decreases.
Reference numeral 40 in FIG. 3 denotes a full-wave rectifier. In this way, the motor 3
The configuration for changing the rotational speed of 3 is generically referred to as rotational speed changing means C, but the configuration can be variously changed in design. Further, such a rotation speed changing means C is provided in the drying unit 31. The rotation speed changing means C may be built in the drying unit 31 or may be provided separately.

When the number of the moisture absorption cartridges 7 mounted on the drying unit 31 decreases, the switch S is switched to decrease the rotation speed of the motor 33 and the heater 30.
By reducing the amount of air passing through, the regeneration and drying of a small number of moisture absorption cartridges 7 can be efficiently performed in a high temperature state. Then, when the number of the moisture absorption cartridges 7 increases, the switch S is switched to increase the rotation speed of the fan 34 to compensate for the insufficient amount of air when a large number of sheets are stacked, and to perform the re-drying with a sufficient amount of air.

The moisture absorbing cartridge 7 of the present invention may be used by inserting it into a narrow space by itself.
Although not shown, the moisture absorbing cartridge 7 may be attached to the blower unit for use.
