The ratio of introduction to the outside air taken into the chamber 14 is rotated and adjusted for opening and closing.

次に作用を説明する。   Next, the operation will be described.

試料を乾燥する際には、前記電気乾燥庫１の前記扉４を開け、前記本体３内の左右の前記トレー受け１３に試料を入れたトレーを載せた後、扉４を閉めて前記電気ヒータ１５および前記送風機１６を作動させ、前記加熱室１４で熱風を発生する。
この加熱室１４で発生された熱風は、熱風路１７に送り出され、この熱風路１７を介して左右の前記トレー受け１３まで送られ、このトレー受け１３部分から前記乾燥室１２内に吹き出される。 When the sample is dried, the door 4 of the electric drying cabinet 1 is opened, the tray containing the sample is placed on the left and right tray receivers 13 in the main body 3, and then the door 4 is closed to close the electric heater. 15 and the blower 16 are operated to generate hot air in the heating chamber 14.
The hot air generated in the heating chamber 14 is sent to the hot air passage 17, sent to the left and right tray receivers 13 through the hot air passage 17, and blown out from the tray receiver 13 into the drying chamber 12. .

この乾燥室１２内に吹き出された熱風は、トレー内の試料を乾燥する。
試料を乾燥した後の熱気は、前記排気口１９を介して外部に排気される。
このとき、試料を乾燥した後の熱気の一部は、内気循環用開口を介して前記加熱室１４に循環される。そして、前記シャッタ２６の開度調整によって内気循環と外気導入との比率を変化させつつ、循環させた内気の一部を再度前記乾燥室１２内に吹き出している。 The hot air blown into the drying chamber 12 dries the sample in the tray.
The hot air after drying the sample is exhausted to the outside through the exhaust port 19.
At this time, a part of the hot air after the sample is dried is circulated to the heating chamber 14 through the opening for circulating the inside air. Then, a part of the circulated inside air is blown out again into the drying chamber 12 while changing the ratio between the inside air circulation and the outside air introduction by adjusting the opening degree of the shutter 26.

また、前記排気口１９を介して外部に排気される熱気は、外気と接することによって結露水が発生する。
そして、発生した結露水が前記排気管部２１の内面に付着して下方に流れた際に、下方に位置する前記水受け部２４によって収集する。
この水受け部２４に収集された結露水は、乾燥熱による自然蒸発、あるいは前記電気乾燥庫１の乾燥作業の終了後に掃除して除去する。 Further, the hot air exhausted to the outside through the exhaust port 19 comes into contact with the outside air to generate dew condensation water.
When the generated condensed water adheres to the inner surface of the exhaust pipe portion 21 and flows downward, the condensed water is collected by the water receiving portion 24 located below.
The condensed water collected in the water receiver 24 is cleaned and removed after natural evaporation due to drying heat or after the drying operation of the electric dryer 1 is completed.

このように、前記排気口１９の外周部位には結露水を受ける水受け部２４を設けたことによって、排気によって生ずる結露水を水受け部２４で効率良く収集することができ、結露水が前記電気乾燥庫１内、つまり前記乾燥室１２内や本体３の外周部位に落下するそれが全くなく、結露水によって各部に錆が発生するという衛生的な不具合や、乾燥効率の低下に繋がる不具合を解消し得る。   As described above, by providing the water receiving portion 24 that receives the dew condensation water on the outer peripheral portion of the exhaust port 19, the dew condensation water generated by the exhaust can be efficiently collected by the water receiving portion 24. The hygienic problem that rust is generated in each part of the electric dryer 1, that is, in the drying chamber 12 and the outer peripheral part of the main body 3, and that each part is caused by condensed water, and a problem that leads to a decrease in drying efficiency. It can be resolved.

更に、前記本体３の上壁９には、前記乾燥室１２内からつまみを移動させて開度調整を行い、この開度調整によって内気循環と外気導入との比率を変化させるシャッタを設ける。 A water receiving portion 24 for receiving condensed water is provided on the outer peripheral portion of the exhaust port 19.
In addition, above the door 4 on the front surface of the electric dryer 1, an outside air intake port 25 is provided for taking outside air into the heating chamber 14.
Further, the upper wall 9 of the main body 3 is provided with a shutter for adjusting the opening degree by moving a knob from the inside of the drying chamber 12 and changing the ratio of the inside air circulation and the outside air introduction by this opening degree adjustment.

また、前記電気乾燥庫１には、前記排気口１９に排気を所定の方向に指向させて排気するとともに取り外し可能な前記排気ダクト３１を設け、この排気ダクト３１には結露水を受ける排気ダクト側水受け部３２を設ける構成とする。
詳述すれば、前記排気ダクト３１は、図４〜図７に示す如く、前記規制板２３よりも更に上方の前記排気管部２１の上端２１ａに取り付ける。
そして、前記排気ダクト３１は、前記排気口１９から上方向に排気される排気の指向方向を、例えば横方向（図４及び図５において前記電気乾燥庫１の後側方向）に変更させるように湾曲させて形成する。
このとき、前記排気ダクト３１内には排気ダクト通路３３が形成されており、この排気ダクト通路３３の外周部位に、図４に示す如く、排気ダクト３１内の結露水を収集するための前記排気ダクト側水受け部３２を設けるものである。
つまり、図４から明らかなように、前記電気乾燥庫１においては、前記排気口１９の外周部位に前記水受け部２４を設けるとともに、この水受け部２４よりも上方の前記排気ダクト３１内の排気ダクト通路３３の外周部位に前記排気ダクト側水受け部３２を設け、前記水受け部２４と排気ダクト側水受け部３２とを上下２段に配設している。 In addition, the electric dryer 1 is provided with the exhaust duct 31 detachable while directing the exhaust gas to the exhaust port 19 in a predetermined direction. The exhaust duct 31 receives the condensed water. The water receiving portion 32 is provided.
More specifically, the exhaust duct 31 is attached to the upper end 21a of the exhaust pipe portion 21 above the restriction plate 23 as shown in FIGS.
The exhaust duct 31 changes the direction of the exhaust exhausted upward from the exhaust port 19 to, for example, the lateral direction (the rear direction of the electric dryer 1 in FIGS. 4 and 5). Curved and formed.
At this time, an exhaust duct passage 33 is formed in the exhaust duct 31, and the exhaust for collecting the dew condensation water in the exhaust duct 31 as shown in FIG. The duct side water receiving part 32 is provided.
That is, as is apparent from FIG. 4, in the electric dryer 1, the water receiving portion 24 is provided at the outer peripheral portion of the exhaust port 19, and the exhaust duct 31 in the exhaust duct 31 above the water receiving portion 24 is provided. The exhaust duct side water receiving portion 32 is provided in the outer peripheral portion of the exhaust duct passage 33, and the water receiving portion 24 and the exhaust duct side water receiving portion 32 are arranged in two upper and lower stages.

さすれば、前記電気乾燥庫１は、上述第１実施例と同様に、試料を乾燥している。
このとき、この電気乾燥庫１による試料の乾燥の際には、上述第１実施例と同様に、前記シャッタ２６の開度調整によって内気循環と外気導入との比率を変化させつつ、循環させた内気の一部を再度前記乾燥室１２内に吹き出している。 In other words, the electric drying cabinet 1 dries the sample as in the first embodiment.
At this time, when the sample was dried by the electric drying cabinet 1, it was circulated while changing the ratio of the inside air circulation and the outside air introduction by adjusting the opening degree of the shutter 26, as in the first embodiment. A part of the inside air is blown out again into the drying chamber 12.

また、前記排気口１９を介して外部に排気される熱気は、前記排気ダクト３１の排気ダクト通路３３を通過した後に外気と接することによって結露水が発生する。
そして、前記排気口１９部分で発生した結露水が前記排気管部２１の内面に付着して下方に流れた際に、下方に位置する前記水受け部２４によって収集する一方、前記排気ダクト通路３３部分で発生した結露水が前記排気ダクト３１の内面に付着して下方に流れた際に、下方に位置する前記排気ダクト側水受け部３２によって収集する。
このとき、結露水の発生状況は、外部に近い前記排気ダクト通路３３部分の方が前記排気口１９部分よりも多い。
このため、たとえ上方に位置する前記排気ダクト側水受け部３２から結露水が溢流しても、下方に前記水受け部２４位置しているため、前記電気乾燥庫１内の前記乾燥室１２や前記本体３の外周部位への落下を確実に阻止できるものである。
前記水受け部２４及び前記排気ダクト側水受け部３２に収集された結露水は、乾燥熱による自然蒸発、あるいは前記電気乾燥庫１の乾燥作業の終了後に掃除して除去する。 Further, the hot air exhausted to the outside through the exhaust port 19 passes through the exhaust duct passage 33 of the exhaust duct 31 and then comes into contact with the outside air to generate condensed water.
When the condensed water generated at the exhaust port 19 is attached to the inner surface of the exhaust pipe portion 21 and flows downward, the condensed water is collected by the water receiving portion 24 positioned below, while being collected by the exhaust duct passage 33. When the condensed water generated in the portion adheres to the inner surface of the exhaust duct 31 and flows downward, the condensed water is collected by the exhaust duct side water receiving portion 32 positioned below.
At this time, the condensed water is generated in the exhaust duct passage 33 portion closer to the outside than in the exhaust port 19 portion.
For this reason, even if condensed water overflows from the exhaust duct side water receiving part 32 located above, the water receiving part 24 is located below, so the drying chamber 12 in the electric dryer 1 The fall to the outer peripheral part of the said main body 3 can be prevented reliably.
Condensed water collected in the water receiving part 24 and the exhaust duct side water receiving part 32 is cleaned and removed after natural evaporation due to drying heat or after the drying operation of the electric dryer 1 is completed.

このように、前記排気口１９の外周部位に結露水を受ける水受け部２４を設けるとともに、前記排気ダクト３１には結露水を受ける排気ダクト側水受け部３２を設けたことによって、排気によって生ずる結露水を水受け部２４及び排気ダクト側水受け部３２で確実かつ効率良く収集することができ、結露水が前記電気乾燥庫１内、つまり前記乾燥室１２内や本体３の外周部位に落下するそれが全くなく、結露水によって各部に錆が発生するという衛生的な不具合や、乾燥効率の低下に繋がる不具合を確実に解消し得る。
また、前記排気ダクト３１の湾曲形状によって排気方向を変更することが可能であることにより、前記電気乾燥庫１の使用時の設置場所の融通性の向上や使い勝手を向上させることができる。 As described above, the water receiving portion 24 that receives the dew condensation water is provided on the outer peripheral portion of the exhaust port 19, and the exhaust duct 31 is provided with the exhaust duct side water receiving portion 32 that receives the dew condensation water, thereby generating the exhaust. Condensed water can be reliably and efficiently collected by the water receiving part 24 and the exhaust duct side water receiving part 32, and the condensed water falls in the electric dryer 1, that is, in the drying chamber 12 or the outer peripheral part of the main body 3. Therefore, it is possible to surely eliminate a hygienic problem that rust is generated in each part due to condensed water and a problem that leads to a decrease in drying efficiency.
In addition, since the exhaust direction can be changed by the curved shape of the exhaust duct 31, it is possible to improve the flexibility of the installation place and the usability when the electric dryer 1 is used.

なお、この発明は上述第１及び第２実施例に限定されるものではなく、種々の応用改変が可能である。   The present invention is not limited to the first and second embodiments described above, and various application modifications can be made.

例えば、この発明の第２実施例においては、排気ダクトを、排気口から上方向に排気される排気の指向方向を、例えば横方向（図４及び図５において電気乾燥庫の後側方向）に変更させるように湾曲させて形成する構成としたが、排気ダクトの排気口を２分割し、上下２段や前後左右の所定の方向に指向させる特別構成とすることも可能である。
さすれば、電気乾燥庫の上部のスペース状況に応じて、排気ダクトの排気口の指向方向を変更させることが可能となり、電気乾燥庫の使用時の設置場所の融通性の向上や使い勝手の向上に寄与し得る。 For example, in the second embodiment of the present invention, the direction of the exhaust that is exhausted upward from the exhaust port through the exhaust duct is, for example, the lateral direction (the rear side of the electric dryer in FIGS. 4 and 5). Although it is configured to be curved so as to be changed, it is also possible to adopt a special configuration in which the exhaust port of the exhaust duct is divided into two parts and oriented in a predetermined direction of upper and lower two steps or front and rear and right and left.
This makes it possible to change the orientation of the exhaust duct's exhaust port according to the space conditions above the electric dryer, improving the flexibility and ease of use of the installation location when using the electric dryer. Can contribute.
