Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Use) The present invention is an epoch-making bedding which can be incorporated in a closet, a storage box or the like to quickly dry a material to be dried such as a futon or a blanket in a stored state. The present invention relates to a drying device.

(Conventional Technology and Problems Thereof) The conventional bedding dryer (A) has a warm air circulation system or a warm air inflow system. In these methods, the temperature is 70 ~ depending on the heater.
Hot air of 80 ° C. is blown out to raise the temperature of the futon (3) to 50 to 60 ° C. to scatter the water contained in the futon (3) to lower the water content. Inside the closet,
The futon (3) is folded and stored in a stacked state. Even if the bedding drier (A) is incorporated in such a closet, warm airflow causes a surface portion of the futon (3). However, even if the surface can be dried, it does not reach the inside and the drying efficiency is very poor. Therefore, in general, the warm air blowing part (5) of the bedding drier (A) is inserted between the futon (3) with the warm air blowing part (5) spread to promote the drying. From the original purpose of the bedding drier (A), the futon (3) cannot be cleaned up because the insertion work is complicated and the futon (3) cannot be put away because it has to be dried in a spread state. Deviates.

Further, wool and duvet are not preferable because they cause thermal deterioration at too high temperature.

Further, it is very difficult to collect the blown warm air, and there is a problem that it is not preferable that hot and humid hot air flow into the room side from the close-up because the humidity in the room becomes high such as during the rainy season.

(Object of the present invention) The present invention has been made in view of the drawbacks of the conventional example,
Contrary to warm air blowing, the purpose is to suck air through the material to be dried, such as a futon, to generate an air flow in the material to be dried, and to collect the moisture of the material to be dried together with the air flow. It is an object of the present invention to provide an epoch-making bedding dryer which can be dried well and which can treat high-humidity air without leaking to the outside.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention comprises: forming an opening (2) for suction in a device body (1) made of a rigid body, and opening the opening (2). The entire periphery of the is the contact surface (4) with which the material to be dried (3) such as a futon or blanket contacts, and the dry opening (2) has an air flow of 3 m ³ / min or more and a static pressure of 20 mm.
A suction device (8) for injecting room temperature air into the material to be dried with a fan of H ₂ O or more, a duct (9) for circulating the high humidity air discharged from the material to be dried, and dehumidifying the high humidity air. Connect with the dehumidifier (13).

The technical means called; is adopted.

(Function) Items to be dried (3) such as folded blankets and blankets are stacked on the contact surface (4) of the bedding dryer (A), and the opening (2) for suctioning by the weight of the substance to be dried (3). The material to be dried (3) is in contact with the entire periphery of the.

In this state, when air is sucked from the suction opening (2) by a suction device (8) such as a fan, the air is forced to flow inside the folded object (3) to be dried. Moisture contained in the substance (3) moves along with this circulating air and is discharged from the suction opening (2).

At this time, if the entire periphery of the suction opening (2) is not covered with the material to be dried (3) and there is a short path leading to even a part of the suction opening (2), the material to be dried is (3)
The air passes through the opening (2) for suction through a short path without passing through the above, resulting in that the material to be dried (3) is not dried uniformly.

(Examples) Hereinafter, the present invention will be described in detail with reference to illustrated examples. As shown in FIG. 1, the plate-shaped device body (1) is 70 to 100 cm square, and has a size such that a material to be dried (3) such as bedding such as a blanket or a blanket can be placed in a folded state, and the bedding The upper surface is flat so that the objects can come into contact with each other by its own weight, and it is made of a rigid body that does not deform the weight or suction force of the object to be dried (3) such as resin molded product, wood material, metal material. There is. A suction opening (2) is formed substantially in the center of the apparatus body (1), and the suction opening (2) is provided with a punching metal or a net for supporting the material to be dried (3). The cover material (6) is fitted. The dustproof filter (7) may be arranged inside the cover material (6). The position of the suction opening (2) is preferably near the center of the device main body (1), and it is closer to the center than where it enters inside by 1/5 or more (preferably 1/3 or more) in width from the peripheral edge. If so, it is unlikely to be affected by misalignment or curling when placing an object to be dried (3) such as a futon. Further, the area of the suction opening (2) is preferably 1/2 or less of the surface of the apparatus main body (1) in contact with the material to be dried (3). This is because when the ratio exceeds 1/2, the negative pressure of the material to be dried (3) generated by the suction device (8) such as a suction fan is small, and an airflow for suction passing through the material to be dried (3) is less likely to occur. And efficient drying becomes difficult. However, a suction device (8) with a large capacity such as a fan may be used, but a commercial fan with a large capacity may have a voltage of 200V.
There is a problem in that it is difficult to apply the present invention because a 100V commercial power source cannot be used and a large capacity has a large noise during operation and is difficult to use indoors.

The suction opening (2) may be provided at a plurality of locations.

A duct (9) communicating with the suction opening (2) is provided on the lower surface of the device body (1).
A suction device (8) such as a fan is installed in the communicating portion of the. The suction device (8) such as a fan used is preferably a sirocco fan, but may be an axial fan. The capacity of the suction fan (8) depends on the area of the suction opening (2) (intake port), but the air volume is 3 m ³ / min or more and the static pressure is 20 mmH ₂
Use O or more. The drying efficiency is almost proportional to the wind speed of the suction opening (2) determined by the air volume and static pressure, and the result of analyzing the characteristics of the intake air speed and the fan (8) shows that the intake air speed = (static pressure) ^It was found to be expressed by ^2/5 x (air volume).

Then, the material to be dried (3) such as a folded blanket or blanket is stacked on the contact surface (4) of the bedding dryer (A), and the material to be dried (3) is placed around the opening (2) for suction. ) Are in contact with each other. Here, the important thing is that the whole circumference of the suction opening (2) is not covered with the material to be dried (3),
If there is even a short path leading to the suction opening (2), the air will flow into the suction opening (2) through the short path without passing through the drying target (3), and the drying target will be dried. Since (3) will not be dried, it is important to cover the entire circumference of the suction opening (2) with the material to be dried (3) so that there is no short path. The peripheral weight of the suction opening (2) is covered by its own weight. When air is sucked from the suction opening (2) in this state, the air is forcibly circulated inside the folded object to be dried (3), and the moisture contained in the object to be dried (3) is removed. With this circulating air, it moves and evaporates, is discharged from the suction opening (2), and the material to be dried (3) is efficiently dried.

FIG. 3 shows the bedding dryer (A) of the present invention incorporated in a shelf (10) of a storage (or a closet), and a duct (9) inside the shelf (10) and inside the backboard (11). And top plate (12)
Dehumidifier (12) that is routed inside and placed on the top plate (12)
The air containing a large amount of moisture sucked from the suction opening (2) is introduced into the dehumidifier (13) and dehumidified by the dehumidifier (13) including a heat exchange system and a water condensing system. , Recycled to dry air and discharged and circulated in the refrigerator. The front of the storage is a door (14) so that the inside of the storage will not have much air inside. The condensed water (15) is appropriately discharged to the outside.

FIG. 4 shows that in the third embodiment, suction openings (2) are opened on both the front and back sides of the apparatus body (1), and the suction openings (2) are inserted between the objects to be dried (3) and the objects to be dried (3) above and below. This is an example of simultaneously drying. In this case, a fan box (16) may be integrally provided at the end of the device body (1) so that it can be carried.

Further, in the third embodiment, when the apparatus main body (1), which is a plate-like body, is formed into a plurality of parallel pipes, and the suction openings (2) are provided on the front and back sides, insertion or folding into a futon or the like is possible. Has the advantage that it will be easier.

(Experimental example 1) Sample 120 g of water was sprayed onto the surface of a cotton bedding blanket of about 100 × 200 mm, which was preliminarily conditioned in a room of 50% RH.
A sample that was left for a time was prepared.

The drying apparatus of the present invention The bedclothing drying apparatus for the experiment has a device body of 80 × 100 cm, and a suction opening is formed in a square shape of 20 × 20 cm in the center of the device body, and the suction opening has a mesh cover. Was used.

The suction fan used had an air volume of 5 m ³ / min, static pressure of 45 mmH ₂ O, and power consumption of 150 W.

Comparative Example On the other hand, as a comparative example, a warm air type futon dryer in which warm air is blown to the futon (wind speed 3 m / sec, heater temperature 80
℃, power consumption 600W) was used.

Measurement method and measurement results The above-mentioned blanket for sample was folded in two and dried in each drying device, and the change in weight of the blanket was measured with time. The drying conditions are 40 to 50% RH and room temperature 10 ° C.

The measurement results are as shown in FIG. The horizontal axis of FIG. 5 is the operating time, and the vertical axis is the weight (g) of water in the futon.

It should be noted that the weight of the remaining water = the weight of the futon at the time of measurement−the weight of the futon before spraying with water.

With a warm-air type futon dryer that blows warm air onto the futon, the temperature inside the futon is only 45 ° C even after 30 minutes of operation, even though the hot air of 80 ° C circulates. , About 2
It was about half the dryness over time.

On the other hand, in the suction type drying device of the present invention, about 90
After a few minutes, the weight returned to that before spraying. Therefore, it was found that sweat and the like generated in daily life can be efficiently removed.

(Experimental Example 2) Next, as an experiment for clarifying the relationship between the fan capacity and the dry amount, the amount of sprayed water of the sample futon used in Experimental Example 1 was changed to 250 g and the wind speed at the opening for suction of the fan was changed. Was changed, and the weight of water removed 1 hour after the start of operation was measured.

The size of the apparatus main body and the size of the opening for suction are the same as in Experimental Example 1.

As shown in the measurement results in FIG. 6, it was found that the weight of the removed water was proportional to the wind speed of the suction opening in the range of water content in this experiment.

(Effect) According to the present invention, a suction opening is formed in a device body made of a rigid body as described above, and the entire circumference of the suction opening is used as a contact surface with which an object to be dried such as a futon or a blanket contacts. Therefore, stack the items to be dried, such as folded blankets and blankets, on the contact surface of the bedding dryer, and keep the items to be dried in contact with the entire area around the suction opening. When sucked by a blower, the inside of the folded material to be dried becomes a negative pressure and the air is forced to flow to a deep part,
Since the water contained in the material to be dried moves along with this circulating air and is discharged from the opening for suction, there is an advantage that the material to be dried can be dried to a deep portion in a short time. is there. In this way, compared to the conventional warm air circulation type drying device, it can be efficiently dried in a folded state, so that it can be applied to a storage box, a pusher, etc. that stores dried objects in a folded state. . Moreover, since it is dried by suction of air and hot air is not blown, the temperature does not rise, and even wool or feathers are not deteriorated by heat. Furthermore, since it is a suction type, it is possible to easily control the air flow direction of the air flow by using ducts etc. to prevent warm air with high humidity from leaking to the room side. However, it does not mean that the living environment will deteriorate.
