Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a dryer for drying futons and the like.

<Prior Art> In order to dry a damp futon, etc., it is common to dry it in the sun to evaporate the moisture in the futon and dry it. However, in that case, it is difficult to carry the heavy futon, and it also has the drawback that it cannot be dried during rainy or cloudy days, and these days there are often no places to dry it.

Therefore, as shown in Fig. 4, a breathable bag 2 is sandwiched between the futons that serve as the drying body 1 indoors, and air is forced into the bag 2 with a blower 3, and melon fan heated with a heating device 4 is sent into the bag 2. I am drying the futon.

<Problems to be Solved by the Invention> However, the above-mentioned prior art has the following problems.

■Since heated air is blown through the futon l, the futon l located below the bag 2 has no place for moisture to escape and is difficult to dry. Therefore, if you try to dry the entire futon, it will take time and effort, such as changing the top and bottom midway through.

■Since the outer surface of the futon 1 is exposed to room temperature, it is difficult for the temperature to rise and moisture cannot completely escape.

■In the case of duvets and wool comforters, raising the temperature may cause them to change in quality, so they need to be dried by blowing air, which requires a long drying process.

In view of the above-mentioned problems, the present invention aims to provide a dryer that can uniformly remove moisture from the entire object to be dried such as a futon and easily dry even special items such as a duvet. Means> The means for solving the problem according to claim 1 of the present invention, as shown in FIG.
It is equipped with a suction device 13 that reduces the pressure inside the container 412 to evaporate the moisture in the dry limb body 1, and sucks and discharges it to the outside of the container 2312.

Moreover, in claim 2, a heating device 2I for ripening the inside of the container 12 according to claim 1 is provided.

<Function> In the means for solving the problem according to claim 1, the dried body l
To dry the object, the object to be dried 1 is placed inside the container I2 and sealed, and the suction device 13 starts suctioning air. Then, the air in the container 12 is sucked out to Uiro by the suction device i1+3, and the pressure inside the container 12 is reduced. Yong i5
When the pressure inside the futon 12 is reduced, the boiling point is lowered, so the water contained in the futon l can be evaporated even at room temperature, and the evaporated water is sucked out of the container, resulting in a volume of 2:+
The dry body 1 in 1 2 becomes dry.

In this way, the dried body 1 can be dried simply by reducing the pressure without heating the inside of the container 12, and moisture can be uniformly removed from the entire body to be dried. Therefore, duvets, wool comforters, etc. can be dried without deteriorating their quality.

Furthermore, since the pressure inside the container is reduced, pests such as mites can be killed.

Moreover, in claim 2, at the same time as the suction device i13 starts suction, the heating device 21 is used to remove the container! Since the inside of the drying device 2 is heated, the moisture in the drying object 1 can be evaporated in a shorter time than when heating is not performed, and the drying object 1 can be dried.

Example Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a vertical cross-sectional view showing the overall structure of a dryer according to a first embodiment of the present invention, and FIG. 2 is a plan view of a tentative air intake.

As shown in the figure, the dryer of this embodiment is used for drying materials such as futons.
A container 512 that seals and stores the container! The container 12 is equipped with a suction device I3 that reduces the pressure inside the container 12 to evaporate the moisture in the dried body 1, sucks it, and discharges it to the outside of the container 12.

The container l2 is made of a plastic bag made of synthetic resin, etc.
As shown in the figure, it is formed in a size that allows the object to be dried, such as a futon, to be folded into quarters and stored. Further, the container 612 includes a storage opening (not shown) for putting in and taking out the object to be dried l;
An opening 12a is provided for communication between the inside and the outside. A suction plate l5 is disposed inside the container l2, and the suction plate l5 has a hollow interior as shown in FIG. A hole l6 is formed.

A connecting pipe 17 passing through the opening 12a and leading to Uiro is formed at one end of the intake plate l5. 7 and the opening 12a are in close contact with each other by a seal or the like so as to maintain an airtight state.

The suction device 13 is composed of a diaphragm type vacuum pump or the like, and as shown in FIG. 1, is airtightly connected to the connecting pipe 17 of the suction plate 15 via a bellows-shaped extension pipe 18.

In the above configuration, in order to dry the futon as the drying body 1, the futon 1 is folded in four and put into the container l2 from the storage opening, and the suction plate l5 is sandwiched between the futons 1 and sealed.

Next, the suction device! When you turn on the power to 3 and start breathing,
Yong! The air in +2 is first sucked into the suction plate 15 through the hole [6] in the suction plate l5, passes through the connecting pipe l7 and the extension pipe 18, and is sucked into the suction device 13. Then, it is discharged to the outside from the suction device I3, and the pressure inside the container I2 is reduced.

By the way, in general, as the atmospheric pressure is lowered, the boiling point of water gradually lowers. For example, the boiling point of water is 100°C at 760 mmHg (atmospheric pressure), but drops to 69°C at 150 mΩHg. Utilizing this principle, if the pressure inside the container 12 is reduced by the suction device 13 to lower the boiling point, the water contained in the futon 1 can be evaporated even at room temperature.

Therefore, even though the pressure inside the container 12 is reduced ("f-no," the moisture in the futon l evaporates, the evaporated moisture is sucked out by the suction device 13, and the futon l in the container 12 dries. Therefore, the futon 1 can be dried simply by reducing the pressure inside the container I2 without heating, and moisture can be removed uniformly over the entire futon.

Furthermore, when drying a dried material such as a down comforter or wool comforter, it can be dried in a short time without deterioration by simply reducing the pressure without heating it.

Furthermore, since the pressure inside the container is reduced, pests such as mites can be killed.

Next, a second embodiment of the present invention will be described based on FIG.

As shown in the figure, the dryer of this embodiment is provided with a heating device 2l for heating the inside of a container 2S+2.

The heating device 21 is a general cord heater type in which a heating element made of copper, cadmium alloy, etc. is coated with heat-resistant nylon or heat-resistant vinyl, and is equipped with a controller (not shown). room temperature(
It is said that it is possible to adjust the temperature down to about 60 degrees Celsius from when the power is turned off. The heating device 21 is arranged inside the intake plate I5 and over the entire surface of the container 12.

The configuration of the pond is similar to that of the first embodiment.

In the above configuration, when the inside of the container 12 is heated by the heating device 21 at the same time as the suction device I3 starts suctioning, the moisture in the dried body 1 is more likely to evaporate in a shorter time than in the first embodiment. At this time, if the object to be dried 1 is heated to about 60° C., moisture can be sufficiently removed.

In addition, in the case of special futons such as wool or feathers, there is a risk of deterioration due to high temperature heating, so turn off the power to the heating device 21.
Or set the temperature of the controller low and dry by just reducing the pressure without applying too much M.

Other functions and effects are the same as those of the first embodiment.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

For example, the heating device may be placed on either the container or the intake plate.

Further, the suction device may be provided inside the container instead of being provided outside the container.

Furthermore, it goes without saying that the dryer can be used for other purposes besides drying bedding and the like.

<Effects of the Invention> As is clear from the above description, according to claim 1 of the present invention, there is provided a container for sealing and storing an object to be dried such as a futon, and a container for storing an object to be dried such as a futon by reducing the pressure inside the container. Evaporate and suction the water out of the container. Since it is equipped with a suction device that discharges moisture to the inside of the container, the object to be dried can be dried simply by reducing the pressure without heating the inside of the container, and moisture can be removed uniformly over the entire object to be dried. can.

Furthermore, when drying an object to be dried such as a down comforter or a wool comforter, it is possible to dry the object in a short period of time without deteriorating the quality of the object, since the object to be dried is simply reduced pressure without heating.

Furthermore, since the pressure of the object to be dried in the container is reduced, pests such as mites can be killed.

Further, according to claim 2, since the Kashima device that heats the inside of the container 4 is provided, if the inside of the container is heated by the heating device at the same time as the suction device starts suction, the drying temperature will be lower than in the case where no heating is performed. It has an excellent effect of making it easier for the water in your body to evaporate in a shorter time.
