Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a drying method and apparatus, and particularly to bedding such as futons and blankets, thick clothing, woolen products, lined products, cushions, and carpets. The present invention relates to a drying method and apparatus suitable for drying.

(Prior Art) Conventionally, devices for drying bedding such as futons, thick clothing, woolen products, lined products, cushions, or carpets (hereinafter simply referred to as bedding, etc.) have been designed to dry a certain amount of air. By placing a permeable air bag between bedding, etc., and forcibly supplying warm air to this air bag, the warm air leaking from the air bag can damage the bedding around the air bag. It is known that it is made to dry foods such as However, with such a drying device, it is necessary to spread out the bedding etc. over a certain area, and the drying itself can only be carried out mainly on the outer surface of the bedding that is in contact with the air bag. The reality is that there is no such thing.

On the other hand, there is a "bathroom hot air device" as proposed in Japanese Patent Application Laid-Open No. 58-130927. Although this device dries clothes in the bathroom, it is also possible to install it in a normal room and dry bedding, etc. If the "warm air device" shown in this L publication is adopted, it would be possible to dry the entire futon, for example, so a dryer with an air bag placed between the futons is recommended. It seems possible to perform efficient drying compared to

However, if you want to dry a futon from its entirety, for example, it is necessary to spread the futon out to some extent (force), and like a typical Japanese house, there is no room for that much space. It would be difficult to use this dryer without one.

Therefore, the inventors have conducted extensive research on methods of drying bedding, etc. without spreading them out, and found that it is possible to supply and suck hot air while the bedding, etc. is sealed. The present invention was completed based on the new knowledge that this method produces good results.

(Problems to be Solved by the Invention) The present invention has been made based on the above-mentioned circumstances, and the problems to be solved are the insufficiency of drying in conventional dryers for bedding, etc. This means that bedding, etc. must be spread out over a certain area.

It is an object of the present invention to provide a drying method and apparatus that can reliably dry bedding and the like in a folded state.

(Means for Solving the Problems) The means taken by the invention of the first claim to solve the following problems are: [Bedding (20), thick clothing, woolen products, kekawa products] Place cushions or carpets in airtight bags (11)
After blowing warm air into the airtight bag (11) to bring the internal temperature to 20°C to 100°C, the air inside the airtight bag (11) is sucked and discharged. Bedding (characterized in that the pressure is reduced to below atmospheric pressure, and one cycle consists of blowing warm air into the airtight bag (11), suction and discharge, and repeating this cycle one or more times) 20)
etc. drying method. ”.

That is, this drying method airtightly wraps the bedding (20) etc. in an airtight bag (11), then blows heated air into the airtight bag (11) and then suctions it. By discharging it to the outside and repeating this operation once or multiple times, bedding (20) and the like are dried.

In this case, the hot air supplied into the airtight bag (11) needs to bring the temperature inside the airtight bag (11) to 20'C to 100C. The reason is that airtight bags (
This is because sufficient drying cannot be performed if the temperature inside the airtight bag (11) is lower than 20°C.
This is because if the temperature inside rises above 100°C, it is dangerous and may cause a fire.

In addition, the means taken by the invention according to the second claim are “bedding (20), thick clothes, woolen products, lined products,
Airtight bag for storing cushions or carpets (11)
This drying device is equipped with a drive unit (12) that sucks and discharges the air inside the airtight bag (11) after supplying hot air into the airtight bag (11). ) via a hose (13), and a second air port (14b) that opens to the outside of the drive unit (12).

14b) via a pipe line (16) to suck air;
15) and a heater (17) installed in the pipe line (16) to heat the air to a constant temperature.
'), the air in the airtight bag (11) is sucked in through the first air port (14a) by the pump (15) and discharged through the second air port (14b). The air from the second air port (14b) is heated by a heater (17) and then supplied into the airtight bag (11) from the first air port (14a) by a pump (15). Drying device (10) for bedding (2o), etc. ”.

In other words, this drying device' (10) embodies the drying method according to the first claim, and is mainly comprised of 'airtight 41I (If) and heated airtight bag (11). A drive unit that sends in air and sucks it (
12). Of course, the drive unit (12) is
A pump (rs) for supplying and suctioning air,
It is equipped with a heater (17) for humidifying the air supplied into the airtight bag (11).

In this case, in order to easily store bedding (20) etc. in the airtight bag (11), the airtight bag (If) is configured to cover the outside of the storage box (19) having a predetermined rigidity. It may also be implemented by

(Function of the Invention) In the drying method according to the first claim configured as above, the bedding (20) etc. are first airtightly wrapped in the airtight bag (11). , (Il
), it is only necessary to dry the parts within ). In other words, with this drying method, not only is there no need to dry anything other than the bedding (20) in the airtight bag (11), but the bedding (20) itself is Even in the folded state shown in the figure, it can be kept sufficiently dry.

In this state, by sending heated air into the airtight bag (11) from the drive unit (12), the airtight bag (11) expands to the state shown in FIG. ) and the outer surface of the bedding (20), etc., and the bedding (20), etc. (is heated from the outside surface side). ,
Bedding (20) If there are pests such as mites lurking in the cause,
These pests have the property of moving to areas that are warmed to about the same temperature as a person's body temperature, so they move to the outer surface of bedding (20) and the like.

After that, if the air inside the airtight bag (1) is sucked by the drive unit (12), moisture and bedding (20
) etc. and pests that have moved there are sucked and discharged to the outside of the airtight bag (11).

Moreover, by suctioning this air, the pressure inside the airtight bag (11) becomes lower than the outside pressure, and the evaporation of moisture in the bedding (20) and other directions is promoted.

By repeating the above operation once or multiple times, the bedding (20) etc. is dried not only on the outside but also inside the bedding (20), etc., while the bedding (20) etc. remains folded. Even if there is, the drying will be done reliably.

The drying device (lO) according to the second claim 1 has substantially the same effect as the above drying method, but
Supply of air into the airtight bag (11) and this airtight bag (11)

In addition, each of the first switching valve (18a) and the second switching valve (18b)
) and the operation of the pump (15) and heater (17) are automatically performed by a known control mechanism (not shown) that works with a timer.

(Example) Next, each of the inventions according to the first claim and the second claim will be simultaneously explained based on an example of the drying device (10) shown in the drawings.

Example 1 FIG. 1 shows an example in which bedding (20) and the like are being dried by the drying device (10) according to the first example. It mainly consists of an airtight bag (11) for airtightly storing bedding (20) and the like, and a drive unit (12) connected to the airtight bag (11) via a hose (13).

The airtight bag (11) may be made of any material as long as it can maintain airtightness, but in this example, a synthetic resin sheet such as polypropylene, a rubber sheet, etc. Alternatively, rubber-treated cotton cloth or the like was used. In addition, since it is necessary to store and take out bedding (20), etc. from this airtight bag (11), a zipper or the like is provided in a part of the bag so that the inside can be opened. .
