(point of view)
A large number of futons used in hospitals, various nursing homes, accommodation facilities, recreational facilities, etc. are not only economically rich, but also helped to promote hygiene and national hygiene. In addition to being used in general, it is not only common that the used items are immediately cleaned and disinfected, but then reused. Even in the futons used in ordinary households located in urban areas, the environment in which futons can be dried in individual households has been increasingly lost, and the number of people in the family environment of couples working together for nuclear families has increased Recently, there is a strong tendency to use cleaning by specialists, and in response to such a tendency, in addition to the traditional so-called futon specialists, we mainly focus on clothes. The cleaning industry has been forced to take countermeasures, and it has become an urgent task to develop a means for efficiently drying in a short time, not only in general laundry, but also in a completely different structure. ing.

(Conventional technology)
As a typical example of a current professional contractor and a commercial futon dryer in the general cleaning industry placed under such circumstances, for example, a box type disclosed in Japanese Patent Application Laid-Open No. 2000-157795 The bedding, mattress, and other beddings are stored in a dry room in a stationary state so that they can be dried and dry air supply means for supplying dry air into the drying room and the bedding using the air permeability of the bedding. There is a `` bedclothes dryer '' invention having a supporting means for supporting the bedclothes so that they can be dried, and like the `` futon dryer '' invention described in JP-A-2001-239095, A gas burner is provided at the top of the machine that has a drying chamber inside, a blower duct is provided in the drying chamber, a hot air blowing duct is provided in the inner bottom, and a blower fan that sends hot air from the gas burner to the drying chamber; There is an exhaust fan that exhausts outside the drying chamber, and the hot air generated by the gas burner is forcibly exhausted while the exhaust hot air inside the drying chamber is forcibly exhausted. Many things have already been developed.

However, such a general commercial futon dryer has a main body formed in a box shape, and has been developed and manufactured to be individually installed and used indoors, so it is easy to move and install. On the other hand, the number of futons that can be dried by a single drying operation is limited, and is not capable of quickly drying a large number of futons. In order to quickly dry the futon, there is no choice but to prepare a plurality of the traditional commercial futon dryers, which not only requires a lot of money to prepare the equipment, but also for maintenance. Labor costs increase due to labor and time being deprived, and even if a large amount of futon is dried, the cost of drying per futon cannot be reduced at once. There is a drawback to say.

As shown in FIG. 2, the air blown into the drying chamber 2 through the respective band-shaped vents 4, 4... Absorbs the heat energy from the steam and is dried to a high temperature. 4 passes through the hook top 96 through the inside of the base pedestal 92 of the saddle horses 9, 9,... Shown in FIG. 4 and FIG. As shown in Fig. 3, the futon F, which is attached in a straddling manner, is forcibly passed through the thickness direction and discharged into the drying chamber 2, and the futon F is heated and contained in the futon F. The water that is in it will be uniformly evaporated.
Although the air in the drying chamber 2 is in a hot and humid state, the air is agitated by the blower fans 51, 51,... Of the agitating mechanism 5, adjusted to a uniform humidity and temperature throughout the interior, and exhausted. Since the hot air with moisture is naturally exhausted from the exhaust port 6 through the duct 61, the moisture is gradually dehumidified according to the drying state of the futons F, F,..., And condensation occurs on the drying chamber 2 wall surface, ceiling surface, etc. Will be blocked.

The control device and switch panel automatically measure the humidity and temperature in the drying chamber 2 and automatically recognize the drying state of the futons F, F,... And the humidity in the futons F, F,. When about 90% of the water is removed, the supply of steam to each of the heat exchangers 3 and 3 is stopped and the blowers 74 and 74 are stopped to wait in the work room 8 that the drying operation is completed. The worker who has received the notification is notified by the lighting of a lamp, a buzzer sound, or the like, or the worker who is performing another work in an outside place, and the worker who has received the notification has the sliding door sash 81 , 81,... Are opened, and the saddle horses 9, 9,... Are moved as shown by solid white arrows in FIGS. Remove futons F, F, ... from each saddle horse 9, 9, ... Put one after another into the drum-type futon dryers 84, 84,... In the room 8 and finish-dry them one after another to dry them almost 100%, and after finishing them softly, take them out and take out the futons F, F,. A series of drying operations are completed.
When performance comparison was performed based on the futon drying operation in which the futon drying system 1 and the conventional futon drying apparatus were actually performed, the results shown in Table 1 were obtained.

    The conventional futon drying apparatus takes about 5.8 minutes to dry one futon when the drying temperature is set to 90 ° C., whereas the futon drying system 1 has a drying chamber 2. When the inside temperature was set to 70 ° C., one futon could be dried in about 3.5 minutes, and the conventional futon dryer required 120 minutes to finish and dry 36 futons. However, since the futon drying system 1 uses the drum-type futon dryer 84, it was possible to finish and dry the 26 futons in 90 minutes. In addition, the amount of heavy oil necessary to dry one futon was 2.59 liters for the conventional type, whereas the futon drying system 1 dries one futon using 1.53 liters. I was able to.

Moreover, when the expenses for one month calculated based on the information obtained by the drying operation were compared, the results shown in the following Table 2 were obtained.

    In the conventional futon drying device, the electricity bill for one month was 38,708.5 yen, while the futon drying system 1 was 7,846.5 yen, If the conventional type dries 62 sheets a day and operates for 25 days, it is 148,925 yen, and the futon drying system 1 dries 103 sheets a day and operates for 25 days at 153,550 yen The conventional type dries 1,550 sheets in 25 days, while the futon drying system 1 was able to dry 2,575 sheets in 25 days.

Furthermore, when comparing the case of drying 103 futons per day, the results shown in Table 3 were obtained.

    When a conventional futon drying device dries 103 futons a day, the amount of heavy oil used for one month (25 days) is 6,675 liters, and the price is approximately 246,975 yen. On the other hand, the futon drying system 1 can be 4,150 liters, and the price can be reduced to about 153,550 yen. Also, it takes a total of 250 hours to dry 103 sheets of futon per day using the conventional type and operate for one month (25 days), while using the futon drying system 1 totals 150 hours. However, according to the futon drying system 1, the electricity cost required at that time is about 38,708.5 yen as described above. It is possible to keep it at 6 yen.

(Effect of Example)
In addition to the features described above, the futon drying system 1 taken up in this embodiment can perform work related to the saddle horse 9 in the work room 8 installed adjacent to the drying room 2. Of the futons F, F,... Into the working room 8 and efficiently straddle the saddle horses 9, 9,. The free casters 93, 93,... Can be easily moved to the drying chamber 2 and placed on the belt-type vents 4, 4,. Furthermore, when collecting the futons F, F,... After finishing drying, the respective saddle horses 9, 9,. Reduces the work load before and after, and a large number of futons F, F, ... are effective even for a relatively small number of workers. Can be dried and processed automatically, and the outside work can be done during the drying process, so the worker must assist or monitor the futon supply during the drying operation. Compared with the futon drying device, it is possible to ensure much higher workability.

    Further, in the initial stage of supplying outside air into the blowing space 22 by the blowing devices 74, 74, the inflowing outside air is sufficiently heated by passing through the heat exchangers 3, 3, so that cold air is introduced into the blowing space 22. Can be surely prevented from entering and temperature unevenness of hot air discharged from the belt-shaped vents 4, 4,... Into the drying chamber 2 can be eliminated, and uniform and efficient drying can be achieved. By supplying only high-temperature air into the air blowing space 22, high heat insulation and heat insulation are ensured, and drying is continued for a while after the supply of steam to the air blowers 74 and 74 and the heat exchangers 3 and 3 is stopped. It becomes possible to continue the drying in the chamber 2, and when the replacement of the futon is repeated one after another and the drying operation is repeated continuously, it will demonstrate high drying performance from the beginning of the restart, making it more efficient That makes it possible to achieve To become.
