(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.

Since it was arranged and forced to supply outside air through the ventilation space under the floor, it was blown to the futon as hot air through the heat exchanger and allowed to pass through to dry, so the hot air immediately after being heated by the heat exchanger It is possible to spray directly on the futon, complete the drying in a short time to ensure the efficiency of the drying work, it is possible to realize a prompt service such as finishing on the same day, and greatly reduce heat loss It is possible to significantly reduce the amount of heat source energy used, and each heat exchanger shares the air blowing space under the floor, so the number and output of air blowers can be minimized. And , It becomes possible to exert a very large effect of fuel costs and electricity costs can be significantly reduced until 1/3 to 1/2 not compared to conventional futon drying apparatus.

    In implementing the present invention having the configuration as described above, the best or desirable mode will be described. First, the drying chamber of the present invention can accommodate a large number of bedding and daily necessities that contain a large amount of moisture after washing, etc., so that a large number of comforters can be uniformly and efficiently dried. It fulfills the function of ensuring a certain degree of hermeticity, and forms an air blowing space of a predetermined depth over an appropriate place under the bottom surface, preferably substantially the entire surface, and the air from the air blowing space is formed on the floor surface. There must be multiple rows of heat exchangers that can pass through, and at least one exhaust port should be formed at appropriate locations such as the ceiling and side walls, and adjacent to each heat exchanger It is desirable to have a work room that can be used for work related to each saddle horse by moving the saddle horse placed in Buildings such as factories and residences that can be installed outside It may be formed by using a part of the building for exclusive use, but heat and noise emitted from humid exhaust, heat source devices and heat exchangers, etc. It is desirable to install the facilities so that they do not adversely affect them.

    The ventilation space is forcibly guided from outside the heat exchangers installed at multiple locations on the floor of the drying room to the outside of the drying room, and then sent to the hanging horses located above the heat exchanger. The heated outside air is continuously blown up to the futons that are attached in a stretched manner, and the function of allowing ventilation is achieved. Each of the heat exchangers arranged at predetermined intervals on the floor surface of the drying chamber. The outside air must be supplied in a substantially uniform pressure, and it must be shaped so that it can be branched, and a pipe duct formed in a branched shape is circulated between the floor surfaces, so that a substantially equal amount of outside air is supplied to each heat exchanger. However, it is desirable to dig into a predetermined depth over almost the entire surface under the floor, and to form a cavity, the depth of which does not hinder the blowing of air Efficient wind flow with good wind speed and pressure It is desirable to set the vertical dimension so narrow that it can be formed, and an additional blower can be installed in a place far from the blower where sufficient wind pressure cannot be obtained, or under the floor where good ventilation is not generated due to the generation of vortex Alternatively, on the downstream side of the heat exchanger on the side close to the air blower, a guide vane plate that allows air to be blown and guided upwards with a part of the air blowing as a dam shape is suspended below the bottom surface of the drying chamber Alternatively, it can be fixed upright on the floor surface of the air blowing space.

    The guide vane plate is located on the downstream side of the heat exchanger near the air blower where sufficient wind pressure cannot be obtained. It functions to increase the wind pressure applied to the exchanger, and can be formed either in front or back with respect to the air blowing or in a right-angled posture, and is not limited to a flat plate shape. It can be formed so as to protrude from either the upper or lower inner wall of the space or from both the upper and lower inner wall surfaces, and it extends in a streamline shape on the downstream side rear surface so as not to generate vortex at the tip edge The formed guide wall surface can be formed.

    A plurality of heat exchangers are arranged at predetermined intervals on the floor surface of the drying room, and a saddle horse can be arranged on the upper side of each, and heat by heat source energy supplied from a heat source device installed at an appropriate place is obtained.

While flowing toward the other end side, the air forcedly supplied from the air blowing space 22 and blown into the drying chamber 2 is heated and laid so as to reciprocate a plurality of times in the depth direction below the bottom surface 21 of the drying chamber 2. The air in the air blowing space 22 is heated while flowing in the steam pipe 41, and then bypassed and guided to the outside of the drying chamber 2 to be circulated and supplied to a boiler (heat source device 4) (not shown). The steam flowing out from the other end of the heat exchangers 3, 3,... Is partly hot water as the temperature is lowered, and is directed in the depth direction below the heat exchangers 3, 3,. Are arranged in a plurality of drain pipes 42, 42,... After heating the air, is induced on the outside of the drying chamber 2, the circulation in the boiler (heat source unit 4), and be utilized.

    The outside air forcibly supplied from the blowers 74 and 74 flows into the blower space 22 from the blower chamber 7 side as indicated by a two-dot chain arrow in FIG. 3 and is guided by the guide vanes 23, 23, and 23. The air exchangers 3, 3, 3 close to the air blowers 74, 74 also generate substantially the same air pressure as the other heat exchangers 3, 3,. However, as shown by the dashed white arrows in FIG. 3, the air is blown out, and the air blown into the drying chamber 2 from the air blowing space 22 through the heat exchanger 3 absorbs heat energy from the steam. .. Are dry and have a high temperature, and pass through the inside of the base pedestal 92 of the saddle horses 9, 9,... Disposed on the heat exchanger 3, and also pass through the saddle top 96. Forced to pass in the thickness direction of the futon F, which is mounted in a straddling manner, is discharged into the drying chamber 2, Through the futon F heated and thus causing the water to evaporate evenly to that contained in the futon F upon.

    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 the heat exchangers 3, 3,... Is stopped and the blowers 74, 74 are stopped. Notify the waiting worker with the lighting of a lamp, a buzzer sound, etc., or notify the worker who is doing other work in the outside place in the same way, Open the sashes 81, 81,... And move the saddle horses 9, 9,..., As shown by the solid white arrows in FIGS. Remove futons F, F, ... from each saddle horse 9, 9, ... in room 8 Put them one after another into the drum-type futon dryers 84, 84,... In the same working room 8, and then finish and dry them almost 100%, finish them softly, then take them out and take out the futons F, F,. This completes the series of drying operations.

    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 for drying one futon was 2.59 · for the conventional type, whereas the futon drying system 1 uses 1.53 · to dry one futon. I was able to.

    Moreover, when the expenses for one month calculated based on the information obtained by the actual 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 per day, the amount of heavy oil used for one month (25 days) is 6,675. The price is approximately 246,975 yen. On the other hand, the futon drying system 1 can be set to 4,150 ·, 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.

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 heat exchangers 3, 3,. In addition, when collecting the futons F, F,... After finishing drying, the respective saddle horses 9, 9,. Reduces the burden of work, and even a relatively small number of workers can efficiently use a large number of futons F, F, ... Can be dried and processed, and the outside work can be done during the drying process, so the traditional futon that the worker has to assist in or monitor the futon supply during the drying operation Compared with the drying device, it is possible to ensure much higher workability.

    Further, by providing the opening / closing control valves 43, 43,... Between the heat source device 4 and the heat exchanger 3, the number of the futons F, F,. If there are heat exchangers 3, 3,... Where the saddle horses 9, 9,... Are not arranged, the heat exchangers 3, 3, etc. corresponding to the positions without the futons F, F,. ......, each opening / closing control valve 43, 43,... Is closed to eliminate unnecessary heat dissipation, thereby realizing an effect of realizing a more efficient drying process.

(Conclusion)
