Description

【０００１】
【発明の属する技術分野】
本発明は電子レンジに関し、より詳しくはドアを外向に突出した半円筒形に構成して、電子レンジの外部の多数位置で調理室の内部が透視できるようにするとともに、調理室に流入した空気が曲面に沿って円滑に流動できるようにして、ドアの内面に水分が凝結することを防止する電子レンジに関するものである。
【０００２】
【従来の技術】
一般に、電子レンジは電装室に設置されたマグネトロンから発生される高周波を用いて、調理室内に置かれた調理物を調理するか暖める器具であって、高周波を調理室の内部に放射して、調理物に含有された水分の分子配列を反復的に変換させることで、飲食物の水分分子間の摩擦熱を起こして調理物を調理するようになっている。
【０００３】
図１は、ドア８が開放された状態の従来の電子レンジの斜視図である。同図に示すように、従来の電子レンジは、ハウジング１と、前記ハウジング１の内部に区画されて設けられた電装室２及び調理室３とを有する。電装室２には、高周波を発生させるためのマグネトロン４と、前記マグネトロン４を冷却させるとともに、調理室を通じて空気を循環させることで、調理物から発生する水分及び匂いを外部へ排出させるための送風ファン５とが設けられる。
【０００４】
調理室３は前面が開放された箱状に形成され、底面３ａが長方形をなし、底面３ａの先端部は調理室３の前面と同一平面をなす。前記底面３ａ上には、調理物が載せられ、マグネトロン４から放射される高周波により調理物が調理されるようにするターンテーブル６と、前記ターンテーブル６を回転可能に支持するための回転ガイド（図示せず）が設けられている。前記ターンテーブル６は調理室３の下部に配置されたモータ（図示せず）に結合され、低速で回転する。
【０００５】
また、開放された調理室３の前面には、ハウジング１の一側に回動可能に結合され、調理室３を開閉するドア８が設けられている。前記ドア８は長方形に形成され、中央部には調理室３の内部が透視できるように多数の透視孔が形成された透視部材９が結合されている。この透視部材９を含むドア８はその前面及び背面共に平面となり、ドア８が閉鎖された状態でドア８の背面が調理室３の前面に接触し、ドア８の前面は平面をなして調理室３を閉鎖する。
【０００６】
したがって、電子レンジが作動すると、マグネトロン４から発生する高周波が調理室３に放射されているうちにターンテーブル６が低速で回転するので、ターンテーブル６上に載せられた調理物が高周波により調理される。
【０００７】
しかし、このように構成された従来の電子レンジは六面体の形状をなし、その中央部に調理室の内部が透視できるように形成された透視部材９がドア８とともに平面をなす構造を有するため、調理の途中で、調理室３に収納された調理物の調理状態を確認するためには、使用者がドア８の前方から透視部材９の高さに合わせて、つまり使用者が上体を屈して調理室３の内部を覗き見なければならない欠点がある。
【０００８】
特に、従来の電子レンジのドア８及び透視部材９が平面状になるとともに、透視孔が形成された部分がドア８の全面積に比べて小さく形成されるため、調理室３の内部を覗き見るためには、透視部材に接近しなければならない。よって、使用者が調理室内で調理される調理物の調理状態を確認することが大変面倒であり、長時間がかかる。さらに、電子レンジによる調理とともにほかの仕事を並行することができず、電子レンジに注意を注ぎつづけなければならない欠点があるものである。
【０００９】
また、従来の電子レンジは、ドア８が平面状になり、調理室３の一側壁に形成された吸気孔（図示せず）を通じて調理室に流入した空気が平面状のドア８にぶつかる構造を有するため、調理のうちに調理物から発生する水分がドアの内面に凝結する現象を十分防止することができず、よって、使用者は平面状のドア８を通じて調理室３の内部を透視することがもっと難しくなる。
【００１０】
【発明が解決しようとする課題】

【００２２】
【発明の実施の形態】
以下、添付図面に基づいて本発明の好ましい実施例を詳細に説明する。
図２及び図３は本発明の一実施例による電子レンジの斜視図であり、図２ではドア３０が開放され、図３では閉鎖されている。
同図に示すように、本発明による電子レンジは、高周波を発生させるためのいろいろの電気部品が設けられる電装室１０と、調理物を調理するための空間を有し、前面が開放されている調理室２０と、調理室２０の開放前面を開閉するためのドア３０とを備える。
【００２３】
前記電装室１０には、調理室２０に高周波を放射するマグネトロン１１と、前記マグネトロン１１を冷却させるとともに、調理室２０内の調理物から発生する水分及び匂いを電子レンジの外部へ排出させるための送風ファン１２とが設けられる。
調理室２０は上壁２１、底面板２２、左右側壁２３、２４、及び後壁（図示せず）からなり、その前面に開口部２５が設けられるので、前面が開放される。調理室２０の前面には、前記開口部２５を開閉するため、本発明によるドア３０が回動可能に結合される。前記調理室２０の開口部２５の縁部には、ドア３０が閉じたとき、ドア３０の縁部と接触して前記開口部２５を密閉するため、平面の四角帯面２６が設けられる。
【００２４】
また、調理室２０の底面板２２上には、調理物が載せられて調理されるようにするターンテーブル２７と、前記ターンテーブル２７を回転可能に支持するための回転支持部（図示せず）とが設けられている。このターンテーブル２７は前記底面板２２の下部に設置されるモータ（図示せず）の駆動により低速で回転しながら、その上に載せられた調理物に高周波が均等に伝達されるようにして調理物を調理することになる。
【００２５】
本発明によるドア３０は、調理室２０の開口部２５を形成する四角帯面２６に密着して高周波の漏洩を防止するため、長方形の縁部をなすフレーム３１と、調理室２０の内部を透視して調理状態を確認し得るように、前記フレーム３１の開口部に配置される透視部材３２とを含む。
フレーム３１には、その縁部の内側面に沿って多数のチョーク溝３１ａが一定の間隔で形成されているので、フレーム３１が調理室２０の前面の四角帯面２６と接触すると、前記チョーク溝３１ａにより調理室２０からの高周波の漏洩が防止される。
【００２６】
透視部材３２は、前記フレーム３１の両側から前方に、つまり調理室２０の前面の外側に曲面をなしながら突出した前面板３３と、前記前面板３３の上部を覆う略半円形の上面板３４と、前記前面板３３の下部を覆う略半円形の下面板３５とからなるもので、全体として前方に略半円筒形に突出した形状を有する。
一方、半円筒形をなすように前方に突出した構造を有するドア３０の透視部材３２が調理室２０とともに調理空間３７を形成するため、調理室２０の底面板２２の先端部２２ａも略半円形に形成され調理室の前方に突出した構造を有する。したがって、ドア３０が調理室２０を閉鎖した状態で、底面板２２の先端部２２ａは透視部材３２の下面板３５上に配置され、半円筒形の透視部材３２の内部が調理空間３７を構成することになる。
【００２７】
透視部材３２の前面板３３と上面板３４には、調理室２０が透視できるように一定大きさの透視孔が稠密に配列されているので、前記透視部材３２の前面板３３と上面板３４を通して調理室２０の内部を覗き見ることができるようになっている。すなわち、本発明による電子レンジは、調理室２０の前方だけでなく上方及び両方から調理室２０を透視することができるので、使用者は電子レンジの付近でほかの仕事をしながらも調理室２０に収納された調理物の調理状態を確認することができる。
【００２８】
一方、透視孔が形成されている透視部材３２の外面には、透明材質で作られた透明窓（図示せず）を付着することで、透視孔を通して調理室の内部が調理室の外部と連通しないようにするとともに、透視部材３２を通して調理室２０の内部を覗き見ることができるようになっている。
ところが、一般に、電子レンジは調理空間内に使用者の眼高に又はそれより低い位置に配置されるため、本実施例では、透視部材３２の下面板３５には透視のための透視孔が形成されていないものにしたが、調理室２０の内部が覗き見られるように、電子レンジの設置高によって下面板３５にも透視孔が形成されたものにすることができる。
【００２９】
図２及び図３に示すように、電子レンジのドア３０の透視部材３２が前方に突出した半円筒形を有するので、調理時に調理物から発生する水分が透視部材３２の内面に凝結する現象を効果的に防止することができる。
【００３０】
図４は電装室１０に流入した外部空気が調理室２０を通過して調理室２０の内部を流動して調理室から排出されるものを示す、電子レンジの斜視図である。
同図に示すように、送風ファン１２により外部空気を電装室１０の内部に吸入し調理室２０を経て調理室２０の外部へ排出させるため、電装室１０の後壁には多数の流入孔１３が設けられ、調理室２０の右側壁２４と左側壁２３には、それぞれ吸気孔１４と排気孔１５が設けられている。
【００３１】
電装室１０の後壁に設けられた流入孔１３の前方には送風ファン１２が配置され、外部空気を吸入し、調理室２０の右側壁２４に形成された吸気孔１４は調理室２０の前面に隣接して配置され、空気がドア３０の透視部材３２側に案内されて円滑に流動できるようにする。また、調理室２０の左側壁２３に形成された排気孔１５は、右側壁２４に形成された吸気孔１４と同様に、調理室２０の前面に隣接して配置され、透視部材３２を経た空気が調理室２０の外部へ円滑に排出されるようにする。マグネトロン１１は流入孔１３と吸気孔１４との間に配置され、マグネトロン１１と吸気孔１４との間には空気案内ダクト１６が配置されるので、マグネトロン１１を通過した空気が空気案内ダクト１６を通して吸気孔１４に案内され調理室２０の内部に流入される。
【００３２】
前記のような本発明による電子レンジの空気循環構造により、吸気孔１４を通じて調理室２０に流入された空気は曲面状の透視部材３２の内面に沿って円滑に流動する。したがって、調理物から発生する水分が、透視部材３２の前面板３３と上面板３４に沿って迅速に流動する空気とともに排気孔１５を通じて外部へ排出されるので、透視部材３２の内側面に水分が凝結する現象を効果的に防止することができる。よって、調理室２０に収納された調理物を透視部材３２を通じてより明らかに透視することができる。
【００３３】
【発明の効果】
以上説明したように、本発明による電子レンジは、ドアの透視部材の前面板が曲面状に前方に突出し、透視部材の上面板と下面板が前記曲面状の前面を覆うように略半円筒形に形成されるため、調理室の外部の多数位置及び角度で調理室の内部を透視することができ、よって、調理室内で調理される調理物の調理状態を電子レンジの外部の多数位置で迅速に確認することができる効果がある。
【００３４】
特に、本発明による電子レンジは、調理室の内部に収納されて調理される調理物を多数位置で確認することができるので、ほかの仕事をしながらも調理室の内部が透視できるので、従来の電子レンジのように調理室の前面近くにきて調理物の調理状態を確認しなくてもよい有利な効果があるものである。
【００３５】
また、本発明による電子レンジは、ドアが曲面状に形成され、吸気孔と排気孔が調理室の両側面に、ドアに隣接して配置されるので、調理室に流入した空気がドアの透視部材の内側面に沿って円滑に流動することにより、透視部材の内側面に水分が凝結する現象を効果的に防止することができ、よってドアの透視部材を通して調理室の内部を鮮明に透視することができる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave oven, and more particularly, to a door having a semi-cylindrical shape projecting outward so that the inside of a cooking chamber can be seen through at many positions outside the microwave oven and air flowing into the cooking chamber. The present invention relates to a microwave oven capable of smoothly flowing along a curved surface to prevent moisture from condensing on an inner surface of a door.
[0002]
[Prior art]
2. Description of the Related Art Generally, a microwave oven is an appliance that cooks or heats a food placed in a cooking chamber using high frequency generated from a magnetron installed in an electrical room, and radiates the high frequency into the cooking chamber. By repeatedly changing the molecular arrangement of the water contained in the food, the food is cooked by generating frictional heat between the water molecules of the food and drink.
[0003]
FIG. 1 is a perspective view of a conventional microwave oven with a door 8 opened. As shown in FIG. 1, the conventional microwave oven has a housing 1, and an electric equipment room 2 and a cooking room 3 partitioned and provided inside the housing 1. The electrical equipment room 2 has a magnetron 4 for generating a high frequency, and a blower for cooling the magnetron 4 and circulating air through the cooking chamber to discharge moisture and smell generated from the food to the outside. A fan 5 is provided.
[0004]
The cooking chamber 3 is formed in a box shape having an open front surface, the bottom surface 3 a is rectangular, and the tip of the bottom surface 3 a is flush with the front surface of the cooking chamber 3. A food is placed on the bottom surface 3a, and a turntable 6 for cooking the food by high frequency radiation emitted from the magnetron 4; and a rotation guide for rotatably supporting the turntable 6 ( (Not shown). The turntable 6 is connected to a motor (not shown) disposed below the cooking chamber 3 and rotates at a low speed.
[0005]
In addition, a door 8 that is rotatably connected to one side of the housing 1 and that opens and closes the cooking chamber 3 is provided on a front surface of the opened cooking chamber 3. The door 8 is formed in a rectangular shape, and a see-through member 9 having a large number of see-through holes is formed at a central portion thereof so that the inside of the cooking chamber 3 can be seen through. The front and back surfaces of the door 8 including the see-through member 9 are both flat. When the door 8 is closed, the back surface of the door 8 contacts the front surface of the cooking chamber 3, and the front surface of the door 8 is flat and the cooking chamber. 3 is closed.
[0006]
Therefore, when the microwave oven operates, the turntable 6 rotates at a low speed while the high frequency generated from the magnetron 4 is radiated to the cooking chamber 3, so that the food placed on the turntable 6 is cooked by the high frequency. You.
[0007]
However, the conventional microwave oven configured as described above has a hexahedral shape, and a transparent member 9 formed at the center of the microwave oven so that the inside of the cooking chamber can be seen through has a structure in which the transparent member 9 and the door 8 form a plane. In order to check the cooking state of the food stored in the cooking chamber 3 during cooking, the user adjusts the height of the transparent member 9 from the front of the door 8, that is, the user leans over the upper body. Therefore, there is a disadvantage that the inside of the cooking room 3 must be peeped.
[0008]
In particular, since the door 8 and the see-through member 9 of the conventional microwave oven have a planar shape, and the portion where the see-through hole is formed is formed smaller than the entire area of the door 8, so that the inside of the cooking chamber 3 is peeped. In order to do so, one has to approach the see-through member. Therefore, it is very troublesome for the user to check the cooking state of the food cooked in the cooking chamber, and it takes a long time. In addition, other tasks cannot be performed at the same time as cooking with the microwave oven, and there is a disadvantage that attention must be paid to the microwave oven.
[0009]
Further, the conventional microwave oven has a structure in which the door 8 has a planar shape, and air flowing into the cooking chamber through an air inlet (not shown) formed in one side wall of the cooking chamber 3 hits the flat door 8. Therefore, it is not possible to sufficiently prevent a phenomenon in which water generated from a cooked product is condensed on the inner surface of the door during cooking, so that the user can see through the inside of the cooking chamber 3 through the flat door 8. Becomes more difficult.
