羽根6の吸引排気作用によって、次第に排気減圧され、
中空室1の内外の圧力差が次第に大きくなるが、成る圧
力差に達した時点で略々平衡状態を維持する。In the configuration described above, when the electric motor 5 is energized and the rotary blade 6 is rotated, the air in the sealed hollow chamber 1 is gradually exhausted and depressurized by the suction and exhaust action of the rotary blade 6.
The pressure difference between the inside and outside of the hollow chamber 1 gradually increases, but when the pressure difference reaches this pressure difference, an approximately equilibrium state is maintained.
この略々一定の平衡状態における中空室1の内外の圧力
差は、回転羽根60回転吸引力の大きさと吸引口4と回
転羽根6の間隙の大きさなどによって定まるが、この平
衡状態は、回転羽根60回転作用が継続する限り維持さ
れる。The pressure difference between the inside and outside of the hollow chamber 1 in this approximately constant equilibrium state is determined by the magnitude of the rotational suction force of the rotating blade 60 and the size of the gap between the suction port 4 and the rotating blade 6. This is maintained as long as the blade 60 rotation action continues.
この平衡状態では、回転羽根6の回転領域内にある摩擦
熱発生部Aにおいて空気の滞溜現象が生じ、回転羽根6
との摩擦作用が反覆継続するので摩擦熱が発生して次第
に温度か上昇する。In this equilibrium state, air stagnation occurs in the frictional heat generating portion A within the rotation area of the rotating blade 6, and the rotating blade 6
As the frictional action continues to be repeated, frictional heat is generated and the temperature gradually rises.
この摩擦熱が中空室1内に伝播して室内を好みの温度に
加熱できる。This frictional heat propagates into the hollow chamber 1, allowing the interior to be heated to a desired temperature.
ところで、中空室1にはその吸引口4に案内板8を円錐
状に固着し、これと平行して間隙部gを形成するように
円錐状の固転板10を設けて旋回層流形成部7を形成し
であるので、摩擦熱を有する気流はこの間隙部gを通っ
て層流状態となって下向し、同時に回転数10を回転さ
せるために旋回流となって遠心作用の下に中空室1の内
周壁に沿って急激な気流を発生させることとなる。By the way, a guide plate 8 is fixed to the suction port 4 of the hollow chamber 1 in a conical shape, and a conical fixed plate 10 is provided in parallel with the guide plate 8 to form a gap g to form a swirling laminar flow forming section. 7, the airflow with frictional heat flows downward through this gap g in a laminar flow state, and at the same time turns into a swirling flow to rotate at a rotational speed of 10 under centrifugal action. A rapid airflow is generated along the inner circumferential wall of the hollow chamber 1.
また回転板10には、その中心に中心孔9を有するので
中空室1内の中心部分の気流は上昇して吸引せられる。Furthermore, since the rotary plate 10 has a center hole 9 at its center, the airflow in the center of the hollow chamber 1 rises and is sucked.
このように中空室1内の空気圧が回転羽根6の回転によ

働きによシ、外周よシ中心側に向って移行する気流の対
流作用が生起し、室1内の温度を所望の設定された温度
に急速に均一化できる。When the air pressure in the hollow chamber 1 is reduced by the rotation of the rotary vanes 6, the swirling laminar flow forming section 7 causes a convection effect of the airflow moving from the outer periphery toward the center. occurs, and the temperature within the chamber 1 can be uniformized rapidly to a desired set temperature.

とができる。Therefore, if an object to be dried, for example, is housed in the hollow chamber 1 as an object to be heated, the release of moisture contained in the object to be dried can be increased by the reduced pressure and the convection action of swirling air currents, and the moisture contained in the object to be dried can be increased. The heating action on the dried material promotes the release of free moisture from the material to be dried, thereby achieving a highly efficient drying action.

度は降下するが、外気の給入分だけ中空室1内の気化蒸
気分が回転羽根6によって外部に排出除去されるので、
乾燥作用をより促進できる。In addition, when the regulating valve 20 is opened to supply outside air from the outside air supply pipe 11 in the process of heating, the temperature inside the hollow chamber 1 decreases, but the temperature inside the hollow chamber 1 decreases by the amount of outside air supplied. Since the vaporized steam is removed by the rotating blade 6,
The drying effect can be further promoted.
さらに中空室1内の温度を予じめ所望の温度に設定して

ことができる。Further, the temperature inside the hollow chamber 1 is set in advance to a desired temperature, and this set temperature and the control valve 20 of the outside air supply pipe 17 are
By linking the opening and closing operations of , outside air is intermittently introduced into the hollow chamber 1 through the outside air supply pipe 7, and automatic operation is performed under desired set temperature conditions. I can do it.
以上、この発明についての実施例を説明したがことに旋

きる他の部材を介装させて旋回層流を得るようにしても
よい。Although the embodiments of the present invention have been described above, the swirling laminar flow forming section 7 is not limited to the above-mentioned configuration, and the lower conical rotary plate 10 is fixed, and the upper conical The guide plate 8 may be rotated, or the upper and lower plates 8 and 10 may be fixed, and another rotatable member may be interposed in the gap g to obtain swirling laminar flow. Good too.
この旋回層流は、中空室1内の減圧度が大きい程、その
力は強く、減圧度が低下するに従って漸次と弱まること
が分っている。It is known that the force of this swirling laminar flow is stronger as the degree of vacuum in the hollow chamber 1 increases, and gradually weakens as the degree of vacuum decreases.
また、中空室1は図示では立方体形状であるがこの形状
は同等特定されるものでなく円筒構造であっても良いこ
とは勿論である。Further, although the hollow chamber 1 is shown to have a cubic shape, this shape is not necessarily specified and it goes without saying that it may have a cylindrical structure.
なお、図示のように立方体形状の場合はその四周の四隅
部に屈曲面を形成して旋回層流の流れ抵抗を逓減させる
こともある。In the case of a cubic shape as shown in the figure, curved surfaces may be formed at the four corners of the four circumferences to gradually reduce the flow resistance of the swirling laminar flow.

エネルギーに役立つと共に中空室内の温度分布を短時間
に均一にできるという特徴を有する。This invention, as shown in the diagonal above, suctions and exhausts the air inside a sealed hollow chamber by the rotational action of a rotating body, maintains the hollow chamber in a reduced pressure state, and maintains the pressure difference between the inside and outside in a substantially constant equilibrium state. A method in which the rotating action of the rotating body is continued to generate frictional heat due to the frictional action between the rotating body and the air, and the gas having this frictional heat is made into a swirling laminar flow state and is caused to descend and convect within the hollow chamber. Since it is related to heat generation, there is no need for a direct heat source such as a conventional heater or fuel as a means of dissipating heat, and it is useful for so-called energy saving, and the temperature distribution within the hollow chamber can be made uniform in a short time. It has the following characteristics.

きるので加熱時間を著るしく短縮して、ことに乾燥機に
広く利用できる利点を有する。Furthermore, since frictional heat is obtained by the frictional action between the exhaust rotating body, that is, the rotary vane, and the air in an equilibrium state, the decompression effect and heat generation effect work synergistically and effectively only by the rotating action of the rotating body. Since the convection phenomenon can be forcibly generated by turning the airflow containing frictional heat into a swirling laminar flow state, the heating time can be significantly shortened, and it has the advantage that it can be widely used, especially in dryers.
