An electrical chamber 16 is provided below the heating chamber 12 of the housing 11. A door 17 is attached below the heating chamber front opening 15 of the housing 11 so as to be openable and closable at the center of rotation in the horizontal direction. The door 17 is provided on the front surface 13 so that the outer shape matches the outer shape of the front surface of the housing 11.

図２（Ａ）に示すように、正面視した扉１７の一方の側方には、表示部１８および操作部１９が配置されている。操作部１９は、加熱室１２に重なって配置される。操作部１９には各種の操作スイッチ２０や調理スイッチ２１が設けられている。   As shown in FIG. 2A, a display unit 18 and an operation unit 19 are arranged on one side of the door 17 as viewed from the front. The operation unit 19 is disposed so as to overlap the heating chamber 12. The operation unit 19 is provided with various operation switches 20 and cooking switches 21.

To the heating chamber 12 again. Thereby, a to-be-heated material is uniformly heated at high temperature.

電気室１６の下方には、加熱室１２に送る蒸気を生成するための水タンク２６が備えられる。水タンク２６の水は、蒸気発生部（図示せず）に供給されて蒸気となる。発生した蒸気は、蒸気発生部と加熱室１２とを接続する蒸気パイプによって加熱室１２に供給される。   A water tank 26 for generating steam to be sent to the heating chamber 12 is provided below the electric chamber 16. The water in the water tank 26 is supplied to a steam generator (not shown) to become steam. The generated steam is supplied to the heating chamber 12 through a steam pipe that connects the steam generating unit and the heating chamber 12.

なお、加熱室１２の上面側には、熱源である上部加熱ヒータ２７が設けられていてもよい。上部加熱ヒータ２７は、発熱することによって、加熱室１２の被加熱物を輻射熱によって加熱処理する。   An upper heater 27 that is a heat source may be provided on the upper surface side of the heating chamber 12. The upper heater 27 heats the object to be heated in the heating chamber 12 with radiant heat by generating heat.

図４に示すように、扉１７は、透過窓２８を備えた扉裏板２９と、扉枠３０と、ハンドル３１と、ハンドルカバー３２と、スクリーン３３と、を有する。扉枠３０の一方の側方には凹部３４が形成され、操作部１９は、この凹部３４を利用して組み立てられている。即ち、凹部３４の裏側には第１プレート３５が設けられる。一方、凹部３４には、底から第２プレート３６と、支持板３７と、回路基板３８と、表側ベースプレート３９と、化粧プレート４０と、が順に積層配置されている。また、表側ベースプレート３９にはボタンユニット４１が組み込まれる。回路基板３８には、液晶パネルからなる表示部１８が実装される。   As shown in FIG. 4, the door 17 includes a door back plate 29 having a transmission window 28, a door frame 30, a handle 31, a handle cover 32, and a screen 33. A recess 34 is formed on one side of the door frame 30, and the operation unit 19 is assembled using the recess 34. That is, the first plate 35 is provided on the back side of the recess 34. On the other hand, a second plate 36, a support plate 37, a circuit board 38, a front side base plate 39, and a decorative plate 40 are laminated in this order from the bottom in the recess 34. A button unit 41 is incorporated in the front base plate 39. A display unit 18 made of a liquid crystal panel is mounted on the circuit board 38.

複数部品を積層して組み立てられる操作部１９は、支持板３７によって凹部３４に支持される。支持板３７は、表示部１８および操作部１９を支持して、扉１７の縦辺部４２に沿って設けられる。操作部１９は、化粧プレート４０と支持板３７とが略同一外形で形成される。図２（Ａ）、（Ｂ）に示すように、筐体１１の外側面を基準面Ｗ０とすると、加熱室側壁１４の厚みはＷ１となる。支持板３７は、基準面Ｗ０から、この加熱室側壁１４の厚みＷ１よりも大きい幅寸法Ｗ２で形成されている。即ち、支持板３７は、縦辺部４２の反対側となる幅方向縁部４３が加熱室１２に重なって配置されている。   The operation unit 19 assembled by stacking a plurality of components is supported by the recess 34 by the support plate 37. The support plate 37 supports the display unit 18 and the operation unit 19 and is provided along the vertical side portion 42 of the door 17. As for the operation part 19, the decorative plate 40 and the support plate 37 are formed with the substantially same external shape. As shown in FIGS. 2A and 2B, when the outer surface of the housing 11 is a reference surface W0, the thickness of the heating chamber side wall 14 is W1. The support plate 37 is formed with a width dimension W2 larger than the thickness W1 of the heating chamber side wall 14 from the reference plane W0. In other words, the support plate 37 is disposed such that the width direction edge portion 43 on the opposite side of the vertical side portion 42 overlaps the heating chamber 12.

図５（Ａ）、（Ｂ）に示すように、操作部１９には、支持板３７に沿って流路４４が形成される。流路４４は、回路基板３８と支持板３７との間、或いは、支持板３７と第２プレート３６との間のいずれに形成されてもよい。本実施形態では、流路４４は、回路基板３８と支持板３７との間に形成される。凹部３４には、扉１７が閉止された状態で、下部側に流路下部開口４５、上部側に流路上部開口４６が形成される。流路下部開口４５と流路上部開口４６とのそれぞれは、流路４４を外部へ通じさせている。流路４４は、流路内の気体が暖められると上昇気流を発生させ、流路上部開口４６から排気を行う。その結果、流路下部開口４５から外部空気が流入する。   As shown in FIGS. 5A and 5B, a channel 44 is formed along the support plate 37 in the operation unit 19. The flow path 44 may be formed between the circuit board 38 and the support plate 37 or between the support plate 37 and the second plate 36. In the present embodiment, the flow path 44 is formed between the circuit board 38 and the support plate 37. In the recess 34, the flow path lower opening 45 is formed on the lower side and the flow path upper opening 46 is formed on the upper side with the door 17 closed. Each of the flow path lower opening 45 and the flow path upper opening 46 communicates the flow path 44 to the outside. The flow path 44 generates a rising air flow when the gas in the flow path is warmed, and exhausts air from the flow path upper opening 46. As a result, external air flows from the flow path lower opening 45.

次に、上記構成を有する加熱調理器１０の作用を説明する。
加熱調理器１０では、図２（Ａ）に示すように、操作部１９が扉１７の側方に配置されているので、従来構成のように、扉１７の下部に配置されている場合に比較して表示部１８、操作部１９が高い位置となり、視認性、操作性が向上する。特に、キッチンの下部に筐体１１をビルトインした場合に、表示部１８の視認や、操作部１９の操作のために屈む必要がなくなり、顕著な効果が得られる。 Next, the effect | action of the heating cooker 10 which has the said structure is demonstrated.
In the cooking device 10, as shown in FIG. 2A, the operation unit 19 is arranged on the side of the door 17, so that it is compared with the case where the operation unit 19 is arranged at the lower part of the door 17 as in the conventional configuration. As a result, the display unit 18 and the operation unit 19 become high, and the visibility and operability are improved. In particular, when the housing 11 is built in the lower part of the kitchen, it is not necessary to bend for visual recognition of the display unit 18 or operation of the operation unit 19, and a remarkable effect is obtained.

また、支持板３７の幅方向縁部４３（図２（Ｂ）参照）が加熱室１２に重なる位置なので、筐体１１を大型化する必要がない。同一サイズの加熱室１２において、仮に支持板３７の幅方向縁部４３を加熱室１２に重ねない位置とした場合、その分、支持板３７が筐体１１の縦辺部４２から外方へ突出する。この突出分に合わせて筐体１１の壁厚を厚くすれば、筐体１１が大型化する。本構成は、支持板３７の一部分を加熱室１２に重ねることでこのような筐体１１の大型化を回避している。   Moreover, since the width direction edge 43 (refer FIG. 2 (B)) of the support plate 37 overlaps the heating chamber 12, it is not necessary to enlarge the housing | casing 11. FIG. In the heating chamber 12 of the same size, if the edge 43 in the width direction of the support plate 37 is not overlapped with the heating chamber 12, the support plate 37 protrudes outward from the vertical side portion 42 of the housing 11. To do. If the wall thickness of the housing 11 is increased in accordance with this protrusion, the housing 11 is enlarged. This configuration avoids such an increase in the size of the casing 11 by overlapping a part of the support plate 37 on the heating chamber 12.

また、加熱室１２に一部分が重なった支持板３７には、加熱室１２からの熱が伝わろうとするが、加熱室１２と支持板３７との間である支持板３７に沿って形成される流路４４により、熱の伝達が低減される。即ち、流路４４には気体が介在し、加熱室１２からの熱が伝達された気体は、高温となって流路４４に上昇気流を生じさせる。加熱室１２からの熱の多くはこの上昇気流に運ばれて流路上部開口４６から排熱され、支持板３７に伝達し難くなる。これにより、操作部１９において、表示部１８や回路基板３８の電装品の冷却が可能となる。   Further, heat from the heating chamber 12 is transmitted to the support plate 37 partially overlapping the heating chamber 12, but a flow formed along the support plate 37 between the heating chamber 12 and the support plate 37. The passage 44 reduces heat transfer. That is, a gas is present in the flow path 44, and the gas to which the heat from the heating chamber 12 is transferred becomes a high temperature and causes an upward air flow in the flow path 44. Much of the heat from the heating chamber 12 is carried by this updraft and exhausted from the upper opening 46 of the flow path, making it difficult to transfer it to the support plate 37. Thereby, in the operation unit 19, the electrical components of the display unit 18 and the circuit board 38 can be cooled.

次に、本発明に係る加熱調理器４７の第２実施形態を説明する。

According to the heating cooker 47, the flow rate of the gas passing through the flow path 44 is increased by the flow path fan 48, and the amount of exhaust heat in the flow path 44 is increased. That is, the cooling effect is improved by forced cooling, and the temperature rise of the display unit 18 in the operation unit 19 and the electrical components of the circuit board 38 is further suppressed.

次に、本発明に係る加熱調理器４９の第３実施形態を説明する。
図７は冷却ファン５０の気体が流路４４に導入される第３実施形態に係る加熱調理器４９の要部拡大側断面図である。
この実施形態に係る加熱調理器４９は、電気室１６、或いは電気室１６の近傍に、マグネトロン駆動電源２２を冷却するための冷却ファン５０が設けられる。冷却ファン５０は、流路４４に、加熱室１２の温度よりも低温の気体を送風する。電気室１６からの排気は、電気室排気口５１と、連通口５２とを形成することによって、流路４４へ導入することができる。連通口５２から扉１７に導入した気体は、一旦、外部を経由して流路４４に取り込まれるようにしてもよい。気体取り込み口５３には、この際の気体を流入し易くするための導入片等を設けてもよい。
この加熱調理器４９によれば、流路４４を通過する気体の流量が、冷却ファン５０によって電気室１６から送られる気体によって増加され、流路４４における排熱量が大きくなる。即ち、強制冷却により、冷却効果が向上し、操作部１９における表示部１８や、回路基板３８の電装品の温度上昇がさらに抑制される。また、専用の流路ファン４８を設ける必要がなくなる。 Next, a third embodiment of the heating cooker 49 according to the present invention will be described.
FIG. 7 is an enlarged cross-sectional side view of a main part of a heating cooker 49 according to the third embodiment in which the gas of the cooling fan 50 is introduced into the flow path 44.
The heating cooker 49 according to this embodiment is provided with a cooling fan 50 for cooling the magnetron drive power supply 22 in the electric chamber 16 or in the vicinity of the electric chamber 16. The cooling fan 50 blows a gas having a temperature lower than the temperature of the heating chamber 12 through the flow path 44. The exhaust from the electrical chamber 16 can be introduced into the flow path 44 by forming an electrical chamber exhaust port 51 and a communication port 52. The gas introduced into the door 17 from the communication port 52 may be once taken into the flow path 44 via the outside. The gas intake port 53 may be provided with an introduction piece or the like for facilitating the inflow of the gas at this time.
According to this heating cooker 49, the flow rate of the gas passing through the flow path 44 is increased by the gas sent from the electric chamber 16 by the cooling fan 50, and the amount of heat exhausted in the flow path 44 is increased. That is, the cooling effect is improved by forced cooling, and the temperature rise of the display unit 18 in the operation unit 19 and the electrical components of the circuit board 38 is further suppressed. Further, it is not necessary to provide a dedicated flow channel fan 48.

次に、上記した実施形態の変形例を説明する。
第１実施形態に係る加熱調理器１０、第２実施形態に係る加熱調理器４７では、流路下部開口４５から流路４４に流入する気体が、水タンク２６のタンク表面５４を通過する。また、第３実施形態に係る加熱調理器４９では、連通口５２から扉１７に導入され、一旦、外部を経由した気体が、水タンク２６のタンク表面５４を通過して流路４４に取り込まれるようにする。
この変形例によれば、流路下部開口４５から流路４４に流入する気体が、水タンク２６の表面に接触した後に、流路４４に取り込まれるので、流路４４に入る直前の気体が、流路４４よりも低温のタンク表面５４を通過することで冷やされる。これにより、流路４４における冷却効果がさらに向上する。 Next, a modification of the above embodiment will be described.
In the heating cooker 10 according to the first embodiment and the heating cooker 47 according to the second embodiment, the gas flowing into the flow path 44 from the flow path lower opening 45 passes through the tank surface 54 of the water tank 26. Further, in the heating cooker 49 according to the third embodiment, the gas introduced into the door 17 from the communication port 52 and once passing through the outside passes through the tank surface 54 of the water tank 26 and is taken into the flow path 44. Like that.
According to this modification, the gas flowing into the flow path 44 from the flow path lower opening 45 is taken into the flow path 44 after contacting the surface of the water tank 26, so that the gas immediately before entering the flow path 44 is It cools by passing through the tank surface 54 lower in temperature than the flow path 44. Thereby, the cooling effect in the flow path 44 is further improved.

従って、本実施形態に係る加熱調理器１０によれば、表示部１８、操作部１９の視認性、操作性を向上できる。   Therefore, according to the heating cooker 10 which concerns on this embodiment, the visibility and operativity of the display part 18 and the operation part 19 can be improved.
