It is related with the microwave oven provided with the door provided so that the front opening part of the said heating chamber might be opened and closed in the front of the.

従来、電子レンジにおいては、外箱で外殻を形成する本体の前部に、加熱室の前面開口部を開閉する扉が回動可能に設けられていると共に、本体の前部の例えば右横に操作部を有する操作パネルが設けられていて、前記操作パネルの後方を機械室とし、その機械室内にマグネトロンやこれの電源装置などを配設する構成となっているのが一般的であった。
一方、近年では、扉に操作部を設け、本体内の加熱室の前面開口部を、本体の前面のほぼ全幅にわたる大きさを有する構成とした電子レンジがある。この種の電子レンジにおいては、加熱室の下方に、マグネトロンやこれの電源装置などを配設するのが一般的であった（例えば、特許文献１参照）。
特開２００１−５９６１６号公報 Conventionally, in a microwave oven, a door that opens and closes a front opening of a heating chamber is rotatably provided at a front portion of a main body that forms an outer shell with an outer box. In general, an operation panel having an operation unit is provided, and the rear of the operation panel is a machine room, and a magnetron, a power supply device thereof, and the like are arranged in the machine room. .
On the other hand, in recent years, there is a microwave oven in which an operation unit is provided on a door, and a front opening of a heating chamber in the main body has a size covering almost the entire width of the front surface of the main body.

JP 2001-59616 A

上記した特許文献１のような構成のものでは、加熱室の下方に、マグネトロンやこれの電源装置などを配設するスペースを必要としている。このため、扉を開けた状態で加熱室を前から見た際に、加熱室の底面が高く見え、加熱室が小さく見えるという欠点があった。また、製品高さには設置上の制限があるため、加熱室の高さを確保できず、本体の外形サイズに対して加熱室を大きくできないという欠点もあった。   In the configuration as described in Patent Document 1 described above, a space for arranging a magnetron, a power supply device thereof, and the like is required below the heating chamber. For this reason, when the heating chamber is viewed from the front with the door open, the bottom surface of the heating chamber looks high and the heating chamber looks small. In addition, since the height of the product is limited in terms of installation, there is a drawback that the height of the heating chamber cannot be secured and the heating chamber cannot be made larger than the outer size of the main body.

本発明は、上記の欠点を解決するためになされたもので、その目的は、本体の前面のほぼ全幅にわたる大きさの開口部を有する加熱室と、操作部を有し、本体の前面に加熱室の前面開口部を開閉するように設けられた扉とを備えたものにおいて、本体の外形寸法を大きくせずに、加熱室の高さ寸法を大きくすることができて、加熱室が大きく見える電子レンジを提供することにある。   The present invention has been made to solve the above-described drawbacks, and an object of the present invention is to provide a heating chamber having an opening having a size covering almost the entire width of the front surface of the main body and an operation portion, and heating the front surface of the main body. With a door provided to open and close the front opening of the chamber, the height of the heating chamber can be increased without increasing the external dimensions of the main body, and the heating chamber looks larger To provide a microwave oven.

上記の目的を達成するために、本発明は、外箱で外殻を形成する本体と、前記外箱内に設けられ、前記本体の前面のほぼ全幅にわたる大きさの開口部を有する加熱室と、操作部を有し、前記本体の前面に前記加熱室の前面開口部を開閉するように設けられた扉とを備えた電子レンジにおいて、前記加熱室内に高周波を供給するためのマグネトロン及びこれの電源装置を、前記加熱室の後方下部に配置したことを特徴とする。   In order to achieve the above object, the present invention includes a main body that forms an outer shell with an outer box, a heating chamber that is provided in the outer box and has an opening having a size that covers almost the entire width of the front surface of the main body. A magnetron for supplying a high frequency into the heating chamber in a microwave oven having an operation unit and including a door provided on the front surface of the main body so as to open and close the front opening of the heating chamber; The power supply device is arranged in the lower rear part of the heating chamber.

本発明によれば、マグネトロン及びこれの電源装置を、加熱室の後方に配置したことにより、加熱室の下方にそれらを配置するスペースを確保する必要がない。このため、加熱室の底面を低くすることができ、本体の外形寸法を大きくせずに、加熱室の高さ寸法を大きくすることができて、加熱室が大きく見えるようにできる。   According to the present invention, since the magnetron and the power supply device thereof are disposed behind the heating chamber, it is not necessary to secure a space for disposing them below the heating chamber. For this reason, the bottom face of the heating chamber can be lowered, the height dimension of the heating chamber can be increased without increasing the external dimensions of the main body, and the heating chamber can be seen larger.

以下、本発明の一実施形態について図面を参照して説明する。
まず、図４において、電子レンジの本体１は、外箱２で外殻を形成していて、矩形箱状に構成されている。外箱２の内部には前面が開口した内箱３が設けられていて、この内箱３の内部を加熱室４としている。この加熱室４の前面の開口部４ａは、本体１の前面のほぼ全幅にわたる大きさの矩形状をなしている。そして、本体１の前面部には、加熱室４の開口部４ａを開閉する扉５が設けられている。この扉５は、図示しない支持部を介して本体１の前下部に上下方向に回動可能に支持されている。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

扉５の前面部には、図３に示すように、上部に手掛け部６が設けられていると共に、下部に複数の操作部７及び表示部８を有する操作パネル９が設けられている。操作部７は、加熱調理の調理モードや調理時間などを設定するためのものであり、また、表示部８は、選択された調理モードや調理時間などを表示するためのものである。本体１の下面には脚部１０が設けられている。   As shown in FIG. 3, a handle portion 6 is provided on the upper portion of the door 5, and an operation panel 9 having a plurality of operation portions 7 and a display portion 8 is provided on the lower portion. The operation unit 7 is for setting the cooking mode and cooking time of cooking, and the display unit 8 is for displaying the selected cooking mode and cooking time. Legs 10 are provided on the lower surface of the main body 1.

上記本体１の背部には、図２に示すように、内箱３（加熱室４）の後方に位置させて機械室１１が形成されていて、この機械室１１は後部カバー１２により覆われている。図２は、内箱３の右側において破断した縦断右側面図、図１は機械室１１を後ろ側から見た破断背面図である。
図１において、機械室１１の下部には、右からマグネトロン１３と、これの電源装置１４と、この電源装置１４を冷却する冷却用ファン１５とが左右方向に直線状に並ぶように配設されている。マグネトロン１３は高周波を発生するもので、その発生した高周波は、加熱室４の下面に設けられた導波管１６を通して加熱室４内に供給されるようになっている。冷却用ファン１５は、送風用の羽根とこの羽根を回転駆動するモータを備えている。 As shown in FIG. 2, a machine room 11 is formed on the back of the main body 1 behind the inner box 3 (heating chamber 4). The machine room 11 is covered with a rear cover 12. Yes. FIG. 2 is a longitudinal right side view broken at the right side of the inner box 3, and FIG. 1 is a broken rear view when the machine room 11 is viewed from the rear side.
In FIG. 1, a magnetron 13, a power supply device 14 thereof, and a cooling fan 15 for cooling the power supply device 14 are arranged in a straight line in the left-right direction at the lower part of the machine room 11. ing. The magnetron 13 generates a high frequency, and the generated high frequency is supplied into the heating chamber 4 through a waveguide 16 provided on the lower surface of the heating chamber 4. The cooling fan 15 includes a fan for blowing air and a motor for rotationally driving the blade.

機械室１１における左右方向の中央部で、かつ上下方向の中央部から上部にかけて、熱風循環機構１７が設けられている。この熱風循環機構１７は、加熱室４内に熱風を供給して循環させるためのもので、ヒータ１８と、送風用の羽根１９と、これらを覆うカバー２０と、羽根１９を回転駆動するモータ２１とを備えている。熱風循環機構１７の図１における左側には、上記冷却用ファン１５の上方に位置させて、熱風循環機構１７冷却用の冷却用ファン２２が配設されている。また、熱風循環機構１７の図１における右側には、制御用配線基板２３が設けられている。   A hot air circulation mechanism 17 is provided at the center in the left-right direction in the machine room 11 and from the center to the top in the up-down direction. The hot air circulation mechanism 17 is for supplying hot air into the heating chamber 4 to circulate the heater 18, a blade 19 for blowing air, a cover 20 for covering these, and a motor 21 for rotationally driving the blade 19. And. On the left side of the hot air circulation mechanism 17 in FIG. 1, a cooling fan 22 for cooling the hot air circulation mechanism 17 is disposed above the cooling fan 15. A control wiring board 23 is provided on the right side of the hot air circulation mechanism 17 in FIG.

そして、機械室１１内には、下部のマグネトロン１３及び電源装置１４と、上部の熱風循環機構１７及び制御用配線基板２３との間を仕切る板状の仕切り部２５が設けられていると共に、上側の冷却用ファン２２の上側にも板状の上部仕切り部２６が設けられている。また、内箱３の左右両側の下部と外箱２との間には、下部仕切板２７，２８が設けられている。これら下部仕切板２７，２８は、内箱３の前後方向に沿って延びている（図２参照）。内箱３の右側壁３ａの前部の上部には、扉５の開閉に応動するインターロックスイッチ２９が設けられている。また、加熱室４の右側（図１においては左側）には、送風ダクト３０が設けられている。この送風ダクト３０は、前端部がインターロックスイッチ２９に臨み、後端部が機械室１１に臨んでいる。   The machine room 11 is provided with a plate-like partition portion 25 that partitions the lower magnetron 13 and the power supply device 14 from the upper hot air circulation mechanism 17 and the control wiring board 23, and the upper side. A plate-like upper partition 26 is also provided above the cooling fan 22. Further, lower partition plates 27 and 28 are provided between the lower portions on both the left and right sides of the inner box 3 and the outer box 2. These lower partition plates 27 and 28 extend along the front-rear direction of the inner box 3 (see FIG. 2). An interlock switch 29 that responds to the opening and closing of the door 5 is provided at the upper part of the front portion of the right side wall 3 a of the inner box 3. A blower duct 30 is provided on the right side of the heating chamber 4 (left side in FIG. 1). The air duct 30 has a front end facing the interlock switch 29 and a rear end facing the machine room 11.

上記構成において、下側の冷却用ファン１５が駆動されると、この冷却用ファン１５の送風作用により、図１及び図２に矢印Ａ１で示すように、本体１の外部の空気が、主に本体１の下部及び前部から機械室１１内に吸入される。そして、その吸入された空気の大部分は、図１及び図２に矢印Ａ２で示すように、電源装置１４及びマグネトロン１３側へ吐出され、これら電源装置１４及びマグネトロン１３が冷却される。これら電源装置１４及びマグネトロン１３を冷却した空気は、図１に矢印Ａ３で示すように、外箱２の内面に沿って機械室１１内の上部へ流れ、図示しない排気口から本体１の上方側へ排出される。   In the above configuration, when the lower cooling fan 15 is driven, the air blown by the cooling fan 15 mainly causes air outside the main body 1 as shown by an arrow A1 in FIGS. It is sucked into the machine room 11 from the lower part and the front part of the main body 1. Then, most of the sucked air is discharged to the power supply device 14 and the magnetron 13 side as shown by an arrow A2 in FIGS. 1 and 2, and the power supply device 14 and the magnetron 13 are cooled. The air that has cooled the power supply device 14 and the magnetron 13 flows to the upper part of the machine chamber 11 along the inner surface of the outer box 2 as shown by an arrow A3 in FIG. Is discharged.

また、上側の冷却用ファン２２が駆動されると、この冷却用ファン２２の送風作用により、上記冷却用ファン１５の場合と同様に図１及び図２に矢印Ａ１で示すように、本体１の外部の空気が、主に本体１の下部及び前部から機械室１１内に吸入される。そして、その吸入された空気の大部分は、図１及び図２に矢印Ａ４で示すように、熱風循環機構１７及び制御用配線基板２３側へ吐出され、これら熱風循環機構１７及び制御用配線基板２３が冷却される。これら熱風循環機構１７及び制御用配線基板２３を冷却した空気は、図１に矢印Ａ５で示すように、機械室１１内の上部へ流れ、図示しない排気口から本体１の上方側へ排出される。   When the upper cooling fan 22 is driven, the air blowing action of the cooling fan 22 causes the main body 1 to move as shown by the arrow A1 in FIGS. 1 and 2 as in the case of the cooling fan 15. External air is sucked into the machine room 11 mainly from the lower part and the front part of the main body 1. And most of the sucked air is discharged to the hot air circulation mechanism 17 and the control wiring board 23 side as shown by an arrow A4 in FIGS. 1 and 2, and these hot air circulation mechanism 17 and the control wiring board are discharged. 23 is cooled. The air that has cooled the hot air circulation mechanism 17 and the control wiring board 23 flows to the upper part of the machine room 11 as shown by an arrow A5 in FIG. .

なお、冷却用ファン１５または２２が駆動された際に、それらから吐出された空気の一部は、図２の矢印Ａ６で示すように、送風ダクト３０を通してインターロックスイッチ２９に吹き当てられ、このインターロックスイッチ２９が冷却される。
このように、冷却用ファン１５または２２が駆動された場合、これら冷却用ファン１５、２２の吸気は、本体１の下側及び前面側から行われ、排気は本体１の上部から行われる。 When the cooling fan 15 or 22 is driven, a part of the air discharged from them is blown to the interlock switch 29 through the air duct 30 as shown by an arrow A6 in FIG. The interlock switch 29 is cooled.
In this way, when the cooling fan 15 or 22 is driven, intake of the cooling fans 15 and 22 is performed from the lower side and front side of the main body 1, and exhaust is performed from the upper part of the main body 1.

図５は、上記構成の電子レンジが、壁３５により囲まれた空間３６に収納された状態が概略的に示されている。このような状態で、電子レンジの冷却用ファン１５または２２が駆動された場合、矢印Ｂ１で示すように、本体１の前部側から吸気され、矢印Ｂ２で示すように、本体１の上部から前方に向けて排気される。従って、上記電子レンジは、そのままビルトインタイプとして使用することが可能である。   FIG. 5 schematically shows a state in which the microwave oven having the above configuration is housed in a space 36 surrounded by a wall 35. When the cooling fan 15 or 22 of the microwave oven is driven in such a state, air is sucked from the front side of the main body 1 as indicated by an arrow B1, and from the upper part of the main body 1 as indicated by an arrow B2. Exhausted toward the front. Therefore, the microwave oven can be used as it is as a built-in type.

上記した実施形態によれば、次のような効果を得ることができる。
まず、本体１の前面のほぼ全幅にわたる大きさの開口部４ａを有する加熱室４と、操作部７を有し、本体１の前面に加熱室４の前面開口部４ａを開閉するように設けられた扉５と備えた電子レンジにおいて、マグネトロン１３及びこれの電源装置１４を、内箱３（加熱室４）の後方に配置したことにより、加熱室４の下方にそれらを配置するスペースを確保する必要がない。このため、加熱室４の底面を低くすることができ、本体１の外形寸法を大きくせずに、加熱室４の高さ寸法を大きくすることができて、加熱室が大きく見えるようにできる。また、加熱室３の下方のスペースを自由に使うことができるため、比較的大きな導波管１６を使用することが可能になり、高周波の制御が容易となる利点もある。 According to the above-described embodiment, the following effects can be obtained.
First, it has a heating chamber 4 having an opening 4a having a size that covers almost the entire width of the front surface of the main body 1 and an operation unit 7, and is provided on the front surface of the main body 1 so as to open and close the front opening 4a of the heating chamber 4. In the microwave oven provided with the door 5, the magnetron 13 and the power supply device 14 thereof are arranged behind the inner box 3 (heating chamber 4), thereby securing a space for arranging them below the heating chamber 4. There is no need. For this reason, the bottom face of the heating chamber 4 can be lowered, the height dimension of the heating chamber 4 can be increased without increasing the external dimensions of the main body 1, and the heating chamber can be seen larger. Further, since the space below the heating chamber 3 can be freely used, it is possible to use a relatively large waveguide 16 and there is an advantage that high-frequency control is facilitated.

また、内箱３後方の機械室１１内において、マグネトロン１３と、これの電源装置１４と、この電源装置１４を冷却する冷却用ファン１５とをほぼ直線状に並ぶように配置したことにより、一つの冷却用ファン１５で、マグネトロン１３及び電源装置１４を効率良く冷却することができる。
さらに、機械室１１内において、下部のマグネトロン１３及び電源装置１４と、上部の熱風循環機構１７との間を仕切る仕切り部２５を設けたことにより、熱風循環機構１７の発生する熱が、マグネトロン１３及び電源装置１４側へ及び難くできる。また、マグネトロン１３及び電源装置１４は冷却用ファン１５により、熱風循環機構１７及び制御用配線基板２３は冷却用ファン２２により、それぞれ独立して冷却することができる。 Further, in the machine room 11 behind the inner box 3, the magnetron 13, the power supply device 14 thereof, and the cooling fan 15 for cooling the power supply device 14 are arranged so as to be arranged substantially linearly. The magnetron 13 and the power supply device 14 can be efficiently cooled by the two cooling fans 15.
Further, in the machine room 11, by providing a partition portion 25 that partitions the lower magnetron 13 and the power supply device 14 from the upper hot air circulation mechanism 17, the heat generated by the hot air circulation mechanism 17 is transferred to the magnetron 13. And it can be difficult to reach the power supply 14 side. The magnetron 13 and the power supply device 14 can be cooled independently by the cooling fan 15, and the hot air circulation mechanism 17 and the control wiring board 23 can be cooled independently by the cooling fan 22.

機械室１１内において、熱風循環機構１７冷却用の冷却用ファン２２と、電源装置１４冷却用の冷却用ファン１５とを上下に並ぶように配置したことにより、それら冷却用ファン２２，１５の吸気経路を同じ方向とすることができる。
内箱３（加熱室４）の左右両外側の下部に下部仕切板２７，２８を設け、冷却用ファン１５，２２による吸気を、本体１の下側及び前面側から行うようにすると共に、排気は本体１の上方から行うようにしたことにより、製品（電子レンジ）を、図５に示すように、そのままビルトインタイプとして使用することが可能となる。 In the machine room 11, the cooling fan 22 for cooling the hot air circulation mechanism 17 and the cooling fan 15 for cooling the power supply device 14 are arranged so as to be lined up and down. The route can be in the same direction.
Lower partition plates 27 and 28 are provided at the lower portions of the left and right outer sides of the inner box 3 (heating chamber 4) so that the cooling fans 15 and 22 can be sucked from the lower side and the front side of the main body 1 and exhausted. Since it is performed from above the main body 1, the product (microwave oven) can be used as it is as a built-in type as shown in FIG.

上記した実施形態において、冷却用ファン１５，２２としては、プロペラファン、シロッコファンなど、各種のファンを使用することが可能である。熱風循環機構１７、及びこれを冷却する冷却用ファン２２は、必要に応じて設ければよい。   In the embodiment described above, various fans such as a propeller fan and a sirocco fan can be used as the cooling fans 15 and 22. The hot air circulation mechanism 17 and the cooling fan 22 that cools the hot air circulation mechanism 17 may be provided as necessary.
