Description

[Detailed description of the invention]

(a) Industrial Application Field The present invention relates to a multi-stage heating unit that can be used in a dryer such as an athlete's foot treatment device that dries by continuously supplying hot air. (b) Prior Art A conventional dryer using a heat-generating unit, such as an athlete's foot treatment device, consists of a heating section using electrical resistance made of nichrome wire, etc., and an air blowing section made of a fan or the like. However, heating using electrical resistance is inefficient and requires separate mechanisms for heating and blowing air, which has the disadvantage of requiring a large number of parts. On the other hand, the present inventor has disclosed Japanese Patent Application Laid-open No. 57-19582 (Japanese Patent Publication No. 60-222263),
A series of publications such as JP-A-57-19583 (JP-A No. 60-222264), JP-A-57-55378 (JP-A-59-52342) and JP-A-57-55379 (JP-A-59-52753) In subsequent inventions, a reduced pressure equilibrium heating method and a drying method or apparatus using the method were proposed. The basic technology is that the air inside a sealed hollow chamber is forcibly sucked in by the rotating action of a rotating body and exhausted to the outside, reducing the pressure inside the room and keeping the pressure difference between the inside and outside at an almost constant equilibrium. and maintaining this equilibrium state, the rotating action of the rotating body is continued to promote frictional action with the air to generate frictional heat, and this frictional heat heats the inside of the hollow chamber. This method also uses the rotating action of a rotating body to forcibly suck the air inside a sealed hollow chamber and exhaust it outside the room, reducing the pressure in the room and keeping the pressure difference between the inside and outside in a nearly constant equilibrium state. The rotating action of the rotating body is continued while maintaining an equilibrium state to promote frictional action with the air to generate frictional heat, and this frictional heat heats the inside of the hollow chamber. This is a reduced pressure equilibrium heating method in which outside air is supplied. The present inventor also proposed a pressurized equilibrium heating method in JP-A No. 57-127779, and found that if an exhaust port with a capacity lower than the exhaust capacity of the rotating body is provided for exhaust, the intake gas will be forced to be discharged to the outside. It was also discovered that the compressor exhibits a kind of pressurizing effect, and therefore generates heat of compression, increasing the temperature more effectively and producing warm air. (c) Problems to be solved by the invention On the other hand, the inventor has disclosed in Japanese Patent Application Laid-Open No. 60-20059 "Hot Air Method and Apparatus" that the invention has a gas inlet and a gas outlet, We proposed a method to create multiple hot air continuously by sequentially connecting the gas outlet and gas inlet of each hollow body with an airtight structure that has a rotating body that rotates with a gas suction capacity greater than the intake amount. did. Further, in the same application, a plurality of rotating bodies having a gas inlet and a gas exhausting capacity larger than the gas inlet and the gas exhausting capacity of the gas inlet and the gas exhausting capacity of the gas inlet and the gas outlet, respectively, are arranged in a hollow body of an airtight structure having a gas inlet and a gas outlet. We proposed a method of creating hot air by connecting hollow bodies in sequence by sequentially connecting the gas outlet and gas inlet of each hollow body. In the same method, even if the capacity of the other rotating bodies is lower than the capacity of the rotating body closest to the intake side, the hot air production capacity of the entire device is still higher than when rotating bodies of the same capacity are used. I also found that there was no difference. In addition, when three or more such hollow chambers are connected in succession, even if the capacity of the rotating bodies is lowered sequentially from the intake side, the hot air generation capacity of the entire device will be lower than when the capacities of all the rotating bodies are the same. I also found that there was no difference. (d) Means for solving the problems Based on these findings, it is an object of the present invention to provide a treatment device having a body storage section. That is, the present invention includes a rotating body that has a gas inlet and a gas outlet, and rotates inside to be able to move gas from the gas inlet to the gas outlet, and a gas inflow restriction provided on the side of the gas inlet from the rotating body. A plurality of hollow bodies having means are connected in sequence by sequentially connecting the gas outlet and gas inlet of each hollow body. A treatment device having a body storage part, which is the largest and is provided outside the rotating body on the most inhalation side. and a rotating body that has a gas inlet and a gas outlet and rotates internally so as to be able to move gas from the gas inlet to the gas outlet; and a gas intake restriction means provided on the side of the gas inlet from the rotating body; A rotating body of hollow bodies in which a plurality of hollow bodies having a gas discharge restriction means provided on the side of the gas discharge port from the body are connected by sequentially connecting the gas discharge port and gas inlet of each hollow body, and a plurality of hollow bodies are installed. To provide a treatment device having a body accommodating part, characterized in that the rotary body on the most inhalation side has the largest gas inhalation capacity, and the body accommodating part is provided outside the rotary body on the most inhalation side. (e) Action: Store the parts of the body that require treatment, such as the legs and the whole body, in the body storage section. When each rotating body is then rotated, gas flows into the hollow body through the gas inlet. At this time, the amount of gas intake is limited by the gas intake limiting means, so the amount of gas sucked in is smaller than the gas discharged by the rotating body, and the amount of gas sucked in is smaller than the amount of gas discharged by the rotating body. The pressure of the hollow body as a whole is also reduced. The pressure difference between the rotating region and other parts, and the pressure difference between the hollow interior and the outside air will gradually increase, but once a certain pressure difference is reached, it will reach an almost equilibrium state in relation to the gas flowing into the vicinity of the rotating region. and maintain this constant pressure state. In this equilibrium state and constant pressure state, the pressure difference inside and outside the rotation region is
This equilibrium and constant pressure state is determined by the magnitude of the rotational suction and exhaust force of the rotating body, the size of the opening area of the gas inlet, and the size of minute gaps, etc., but this equilibrium and constant pressure state is maintained as long as the rotating action of the rotating body continues. will be maintained for as long as possible. In this equilibrium state, it is assumed that air stagnation occurs in the rotating region of the rotating body, and as frictional action continues and repeats between the rotating body and the stagnant gas, frictional heat is generated and the temperature gradually rises. The warm air heated by this frictional heat passes through a small gap and is discharged from the gas outlet to the exhaust port. If a gas discharge restriction means is provided on the gas discharge port side, the gas sucked into the hollow body will be forcibly discharged to the outside, so a kind of pressurizing effect will be exerted on the gas discharge port side. guessed,
With the generation of compression heat, it is possible to further increase the exhaust gas temperature. Furthermore, since a plurality of hollow bodies are arranged in series, it is possible to increase the temperature in stages and make the final exhaust temperature high. In this case, if the opening area of the gas outlet of each hollow body is set so that the exhaust capacity is smaller than the exhaust capacity of the rotating body installed in the hollow body, the pressure near the gas outlet will tend to increase. Since air is taken in by a rotating body installed in a hollow body adjacent to the continuous exhaust side, the area near the gas discharge port of the hollow body on the most exhaust side eventually becomes high pressure, and a kind of pressurizing effect is created in that part. It is estimated that the temperature increases more effectively with the generation of compression heat. In this invention, a plurality of hollow bodies are connected in series, and the output ratio of each motor is made smaller sequentially from the intake port side to the discharge port side, but the final output ratio is smaller than when the output of each motor is the same. There is almost no change in the temperature of the heated air. (F) Examples Below, Fig. 1 shows a central sectional view of an embodiment in which the present invention is used as an athlete's foot treatment device, Fig. 2 shows a central sectional view of an embodiment in which the invention is used for treatment of the whole body, and other embodiments. The explanation will be made according to FIG. 3, which shows a central cross section. 1 is a dry heat treatment device;
In the embodiment shown in FIG. 1, it is used for treatment of human feet, for example, athlete's foot, so it has a chamber-shaped body storage section 3 capable of accommodating a human foot, which is an object 2 to be treated.
The embodiment shown in FIGS. 2 and 3 is used for treating the entire human body, so the entire human body, which is the object to be treated 2, can be stored therein, and there is a body storage section 3 in which the human body, such as a bed, can be lied down. A heat storage material may be installed inside the body storage section 3. The structure may be such that there is no gap between the periphery of the treatment object inlet 4 of the treatment object 2 in the body storage section 3 and the treatment object 2. That is, as shown in FIG.
A band-like material made of a flexible material such as rubber is fixed to the periphery, and the periphery of the object 2 to be treated is tightly adhered when the object to be treated 2 is inserted. 5 is a hollow body, and the hollow body 5 has an airtight structure, and has a gas inlet 6 and a gas outlet 7 having a larger opening area than the gas inlet. In the embodiment shown in FIGS. 1 and 2, the hollow body 5 is installed outside the body storage area 3, but it may be installed inside the body storage area 3 as shown in FIG. 8 is a rotating body, which is composed of rotating blades such as a propeller fan or a Shirotsuko fan. The rotating bodies 8 are rotatable by electric motors 9 installed in each of the hollow bodies 5 in a direction in which gas can be sucked in from the gas inlet 6 and gas can be discharged from the gas outlet 7. In this invention, FIGS.
As shown in Fig. 3, a plurality of hollow bodies are connected, and the gas outlet 7 and gas inlet 6 of each hollow body 5 are successively connected in a sealed state, and the hollow body on the most exhaust side is connected. A gas outlet 7 is opened to the body storage section 3.
g is a minute gap formed between the inner wall of the hollow body 5 and the rotating body 8, and R is the rotation area of the rotating body 8. The hollow body 5 may be provided with a heat storage material. The gas inlet 6 is designed so that the gas inlet capacity of the gas inlet 6 formed in each hollow body 5 is greater than that of the gas inlet 6 formed in the corresponding hollow body 5 during normal rotation of the rotating body 8 installed in the corresponding hollow body 5. It is necessary to set the opening area. In this embodiment, the gas exhaust ports are further arranged such that the gas exhaust capacity during normal rotation of the rotating body 8 installed in the corresponding hollow body is greater than the gas exhaust capacity of the gas exhaust ports 7 formed in each hollow body. Set the opening area of 7. In the embodiments of the present invention shown in FIGS. 1, 2, and 3, the capacity of each rotating body 8 decreases from the intake side to the exhaust side, and each electric motor 9 that rotates the rotating body 8 The output of the motor is approximately 1/2 that of the electric motor adjacent to the intake side. That is, the ratio (Kw) of the output of each electric motor is about 3 to 4:2:1 from the intake port side to the exhaust port side. Therefore, when the rotating body 8 is rotated by the electric motor 9,
The gas in the body storage part 3 flows into the hollow body 5 from the gas inlet 6. At this time, the opening area of the gas inlet 6 is the same as that of the rotating body 8 installed in the corresponding hollow body 5.
Since the gas suction capacity is limited to less than the gas suction capacity of the rotor 8, the amount of gas sucked in is smaller than the gas discharged by the rotor 8, and the pressure is reduced in the rotation region R of the rotor 8 compared to other parts. The hollow body as a whole is also depressurized. The pressure difference between the rotating region R and other parts and the pressure difference between the rotating body and the outside air will gradually increase, but once they reach a certain pressure difference, they will be almost balanced in relation to the gas flowing into the vicinity of the rotating region R. condition is reached and this constant pressure condition is maintained. This equilibrium state,
The pressure difference between the inside and outside of the rotation region R in a constant pressure state is determined by the magnitude of the rotation suction and exhaust force of the rotor 8 and the gas intake port 6.
This equilibrium and constant pressure state is maintained as long as the rotating action of the rotating body 8 continues, although it is determined by the size of the opening area of the , the size of the minute gap g, etc. In this equilibrium state, a phenomenon of air stagnation occurs in the rotation region R of the rotor 8, and the frictional action continues repeatedly between the rotor 8 and the stagnant gas, so that frictional heat is generated and the temperature gradually rises. This frictional heat is transmitted from the hollow body 5 into the body storage part 3 and heats the object to be treated 2. However, when the hollow body 5 is installed inside the body storage part 3 as shown in FIG. 3, it is more efficient. The inside of the body storage section 3 is heated. When heating the inside of the body storage section 3, gas such as air inside the body storage section 3 is sucked in through the gas inlet 6 and discharged to the outside through the gas exhaust port 7. The object 2 to be treated is dried and heated by drying by discharging the moisture inside the air to the outside, thereby treating skin diseases such as athlete's foot. At this time, more gas than the gas flowing in from the treatment object import port 4 is transferred to the gas inlet 6,
When the pressure inside the body storage section 3 is reduced by discharging the gas through the gas outlet 7, moisture dissipation from the treated object is further promoted. If the gap between the treatment object insertion port 4 and the treatment object 2 is reduced or sealed, the decompression effect will be further improved, and the treatment effect will also be improved. If the opening area of the gas exhaust port 7 is set to a smaller exhaust capacity than the exhaust capacity of the rotating body 8, the gas sucked into the hollow body 5 will be forcibly discharged to the outside. 7 exhibits a kind of pressurizing effect, and is accompanied by the generation of compression heat, making it possible to further increase the exhaust gas temperature. As shown in FIGS. 1 to 3, since a plurality of hollow bodies 5 are arranged in series, it is possible to increase the temperature in stages and make the final exhaust temperature high. In this case, if the opening area of the gas outlet of each hollow body 5 is set to have a smaller exhaust capacity than the exhaust capacity of the rotating body 8 installed in the hollow body, the pressure near the gas outlet 7 tends to increase. However, since the air is taken in by the rotary body 8 installed in the hollow body 5 adjacent to the continuous exhaust side, the area near the gas discharge port of the hollow body 5 on the most exhaust side eventually becomes high pressure, and a kind of It exhibits a pressurizing effect, and the temperature rises more effectively with the generation of compression heat. In the case of three consecutive hollow bodies 5, if the gas intake and discharge capacity of the electric motor 9 that drives the rotating body installed in each hollow body is the same, the pressure inside each hollow body 5 will change from the intake port side to the exhaust port side. The ratio changes to 1:1/2:1/3 as you go. As shown in FIGS. 1 to 3, when the output ratio of each electric motor 9 is gradually decreased from 3 to 4:2:1 from the intake port side to the exhaust port side, the output ratio of each electric motor 9 is There is almost no difference in the temperature of the hot air finally obtained compared to when the output is the same. In this case, the opening area of the gas inlet 6 of the hollow body 5 on the most intake side needs to be of a size that can create a reduced pressure equilibrium state in the rotation region R of each rotating body. Embodiment 1 As shown in FIG. 4, hollow bodies 5 (), 5 with an airtight structure having a gas inlet and a gas outlet
A motor (750W) is installed at () and 5() to drive fans of the same size. The gas inlets of each hollow body each have a diameter of 270 mm. When the hollow bodies are connected in this order from the intake side and each rotating body is driven, the values shown in Table 1 are obtained for the changes over time in the current used by each motor, the intake temperature, and the ventilation temperature. Then, by connecting the hollow bodies in the order of , from the intake side, the values shown in Table 2 are obtained. Then, by connecting the hollow bodies from the intake side in this order, the values shown in Table 3 are obtained. In either case, the amount of current is greatest on the intake side and gradually decreases toward the exhaust side.
