Description

本発明は加熱調理器、特に、引き出し自在なグリル扉が設置されているグリル室を有する加熱調理器に関するものである。   The present invention relates to a cooking device, and more particularly, to a cooking device having a grill chamber in which a pullable grill door is installed.

システムキッチンに組み込まれたり、キッチンキャビネットにセットされる加熱調理器は、上面に載置された被加熱物を加熱するための加熱手段(誘導加熱コイル、ガスバーナ等)と、側面から内部に挿入された被加熱物を加熱するためのグリル加熱室(電気ヒータ、ガスバーナ等が設置されている)と、を有している。そして、グリル加熱室には被加熱物を出し入れするためのトレー(たとえば、魚等を載置するための載置網が設置されている)が配置され、トレーとグリル扉は一体化しているから、トレーをグリル加熱室に押し込んだ際、グリル扉によってグリル加熱室はシールされる。また、グリル扉には「とっ手」が設けられ、トレーの出し入れを容易にしている。   The cooking device that is built into the system kitchen or set in the kitchen cabinet is inserted into the interior from the side with heating means (induction heating coil, gas burner, etc.) for heating the object to be heated placed on the upper surface. And a grill heating chamber (with an electric heater, a gas burner, etc.) for heating the object to be heated. In the grill heating chamber, a tray (for example, a placement net for placing fish etc. is placed) for placing and removing the object to be heated is arranged, and the tray and the grill door are integrated. When the tray is pushed into the grill heating chamber, the grill heating chamber is sealed by the grill door. In addition, the grill door is provided with a “hand” to facilitate loading and unloading of the tray.

したがって、調理者はとっ手に手を掛けて、トレーを出し入れしたり、グリル加熱室を閉じたりすることができる。また、グリル加熱室には外気が吸引されると共に、加熱に伴って発生した煙等は所定の排気口から排出されている。通常、調理者が立つ側(前方に同じ)から吸気し、調理者から離れた側(後方に同じ)から排気されている。
そこで、グリル加熱室からの輻射や電熱によってとっ手が過熱しないように、とっ手に通気孔を設け、これを通過する空気によってとっ手を冷却しようとする発明が開示されている(例えば、特許文献1参照)。
Therefore, the cook can reach out and put the tray in and out or close the grill heating chamber. In addition, outside air is sucked into the grill heating chamber, and smoke generated by heating is discharged from a predetermined exhaust port. Normally, the air is sucked from the side where the cook stands (the same in the front) and exhausted from the side far from the cook (the same in the rear).
Therefore, an invention has been disclosed in which a vent is provided in the hand so that the hand is not overheated by radiation or electric heat from the grill heating chamber, and the hand is cooled by air passing through the hole (for example, a patent). Reference 1).

実開平2−137610号公報(第3−4頁、図2)Japanese Utility Model Publication No. 2-137610 (page 3-4, FIG. 2)

しかしながら、特許文献1に開示された発明は、とっ手の手掛け部の裏側に矩形状の透孔から成る通気孔を形成し、遮熱板および後板の通気孔に対応する位置にも矩形状の透孔を設け、さらに、トレーの枠体にも通気孔に対向する位置に一対の透孔を設けたものであるため、以下の問題があった。
(あ)調理者がとっ手の手掛け部に手を掛けるため、このとき、通気孔が塞がれて吸気不良が生じるおそれがある。
(い)空気の流れが2系統に単純化されるため、かかる空気の流れの内外において被加熱物に冷却ムラ(加熱ムラ)が生じる。
However, in the invention disclosed in Patent Document 1, a vent hole including a rectangular through hole is formed on the back side of the handle portion, and a rectangular shape is formed at a position corresponding to the vent hole of the heat shield plate and the rear plate. Further, there are the following problems because the tray frame is provided with a pair of through holes at positions facing the vent holes.
(A) Since the cook puts his hand on the handle portion of the hand, the air hole is blocked at this time, and there is a possibility that an intake failure may occur.
(Ii) Since the air flow is simplified to two systems, uneven cooling (heating unevenness) occurs in the heated object inside and outside the air flow.

本発明は、前記問題を解決するためになされたもので、調理者によって通気孔が塞がれることがなく、さらに、吸引した空気を分散してグリル加熱室に吹き出し、冷却ムラを防止することができる加熱調理器を得ることを目的とする。   The present invention has been made in order to solve the above-mentioned problem, and the air holes are not blocked by the cook. Further, the sucked air is dispersed and blown into the grill heating chamber to prevent uneven cooling. The object is to obtain a cooking device that can cook.

本発明に係る加熱調理器は、被加熱物を収納自在なグリル加熱室と、該グリル加熱室の前方に設置された進退自在なグリル扉と、前記グリル加熱室の内部に設置された発熱体と、前記グリル加熱室の後方に設置された排気手段と、を具備する加熱調理器であって、
前記グリル扉の前面に前方に突出するとっ手と、前記グリル扉の側方寄りに前記グリル加熱室に連通する吸気孔と、が形成されていることを特徴とする。

FIG. Alternatively, it may be supported by the dish support frame 31. In addition, a portion corresponding to the tray support frame 31 may be formed on the mounting tray 30 itself.

(天板)
天板70の上面には、鍋載置サークル71a、71b、71c(以下まとめて「鍋載置サークル71」と称する場合がある)が描かれ、天板70の下面でそれぞれの直下に加熱体72a、72b、72c(以下まとめて「加熱体72」と称する場合がある)が設置されている。加熱体72a、72b、72cは、本体10の前面に設けられた前面操作部11に設置されている電源スイッチ73a、73b、73cによって、あるいは枠体80の前方に設けられた天板操作部81に設置されている電源スイッチ74a、74b、74cによって、操作されるものである。なお、操作や調理の状態は、天板70に設けられた表示部75に表示される。
(Top board)
On the top surface of the top plate 70, pot placing circles 71a, 71b, 71c (hereinafter sometimes collectively referred to as “pan placing circle 71”) are drawn. 72a, 72b, 72c (hereinafter may be collectively referred to as "heating body 72") are installed. The heating bodies 72 a, 72 b, 72 c are provided by power switches 73 a, 73 b, 73 c installed in the front operation section 11 provided on the front surface of the main body 10, or a top panel operation section 81 provided in front of the frame body 80. It is operated by power switches 74a, 74b, 74c installed in the. The state of operation and cooking is displayed on the display unit 75 provided on the top board 70.

(グリル扉)
図3〜図5は、本発明の実施形態に係る加熱調理器におけるグリル扉を模式的に示すものであった、図3は部分を分離して示す斜め前方から後方に向かって見た斜視図、図4は斜め後方から前方に向かって見た斜視図、図5は風路を示す斜視図である。
(Grill door)
3 to 5 schematically show grill doors in the heating cooker according to the embodiment of the present invention, and FIG. FIG. 4 is a perspective view seen obliquely from the rear to the front, and FIG. 5 is a perspective view showing the air path.

(吸気孔)
図3において、グリル扉40の表板41の前面に前方に突出するとっ手50が設けられて、表板41の側方寄りに貫通する吸気孔45a、45b(以下まとめて「吸気孔45」と称する場合がある)が形成されている。図3において、吸気孔45a、45bは6個の丸孔を示しているが、本発明はその数量や形状をこれに限定するものではない。
(Intake hole)
In FIG. 3, a handle 50 is provided on the front surface of the front plate 41 of the grill door 40 so as to project forward, and the intake holes 45 a and 45 b (hereinafter collectively referred to as “intake holes 45”) penetrating to the side of the front plate 41. May be formed). In FIG. 3, the intake holes 45a and 45b show six round holes, but the present invention does not limit the number and shape thereof.

なお、「表板41の側方寄り」とは、調理者がとっ手50に手を掛けた際、手の位置に一致しない範囲を指し、たとえば、表板41の幅方向の中央範囲である約100〜150mmを除く側縁41a、41b寄りの範囲を指している。したがって、図3に示すような表板41の全幅に渡るとっ手50においては、とっ手50の中央範囲である約100〜150mmを除く、側縁41a、41b寄りの範囲を指している。あるいは、とっ手50が表板41の幅方向の中央範囲である約100〜150mmの範囲に設置された場合には、とっ手50を除く側縁41a、41b寄りの範囲を指している。   Note that the “side of the front plate 41” refers to a range that does not match the position of the hand when the cook places the hand 50 on the handle 50, for example, the central range in the width direction of the front plate 41. It indicates the range near the side edges 41a and 41b except for about 100 to 150 mm. Therefore, the grip 50 across the entire width of the front plate 41 as shown in FIG. 3 indicates a range near the side edges 41a and 41b, excluding about 100 to 150 mm which is the central range of the grip 50. Or when the handle 50 is installed in the range of about 100-150 mm which is the center range of the width direction of the surface board 41, the range near side edge 41a, 41b except the handle 50 is pointed out.

(とっ手)
とっ手50は、表板41に略垂直なフランジ部51と表板41に略平行な手掛け部52とを具備する断面略L字状であって、表板41の全幅に渡って配置され、平面視においてアーチ状を呈している。すなわち、とっ手50の端部50a、50b(手掛け部52の端部52a、52bに同じ)は、それぞれ表板41の側縁41a、41bに設置(接続)されている。
したがって、正面視において、吸気孔45はとっ手50の手掛け部52に覆われて、直接視認することができない。なお、手掛け部52の後面と表板41の前面との間隔が、端部50a、50bに近づく程狭くなっているものの、吸気孔45の前方には隙間が形成されているから、大気はかかる隙間(とっ手空間59に同じ)から吸気孔45を通過してグリル扉40の内部に吸引される。
(Hand)
The handle 50 has a substantially L-shaped cross section including a flange portion 51 substantially perpendicular to the front plate 41 and a handle portion 52 substantially parallel to the front plate 41, and is disposed over the entire width of the front plate 41. It has an arch shape in plan view. That is, the end portions 50a and 50b of the handle 50 (same as the end portions 52a and 52b of the handle portion 52) are installed (connected) to the side edges 41a and 41b of the front plate 41, respectively.
Therefore, in the front view, the air intake hole 45 is covered with the handle portion 52 of the handle 50 and cannot be directly visually recognized. In addition, although the space | interval of the rear surface of the handle 52 and the front surface of the front plate 41 becomes narrower as it approaches the end portions 50a and 50b, a gap is formed in front of the air intake hole 45, so that air is applied. The air is sucked into the grill door 40 from the gap (same as the handle space 59) through the intake hole 45.

また、とっ手50はアーチ状であるため、手掛け部52の端部50a、50bに近い範囲は、手掛け部52の後面と表板41の前面との間隔が狭くなり、調理者が手(指に同じ)を掛けることが困難になっている。このため、調理者のかかる動作によって吸気孔45が塞がれるおそれがない。また、万一、グリル加熱室20の圧力が上昇して熱気が逆流し、吸気孔45からとっ手空間59に熱気が噴出した場合であっても、当該熱気噴出範囲には調理者の手が無いから、手に熱気が触れることがない。   In addition, since the handle 50 has an arch shape, in the range close to the end portions 50a and 50b of the handle 52, the distance between the rear surface of the handle 52 and the front surface of the front plate 41 is narrowed, and the cook can The same). For this reason, there is no possibility that the intake hole 45 is blocked by the operation of the cook. In the unlikely event that the pressure in the grill heating chamber 20 rises and the hot air flows backward, and hot air is ejected from the intake hole 45 to the hand space 59, the cook's hand is in the hot air ejection range. Because there is no, heat does not touch the hand.

(仕切壁)
さらに、グリル扉40側方寄りには、とっ手50の後面とグリル扉40の表板41とを連結する仕切壁53a、53b(以下まとめて「仕切壁53」と称す場合がある)が設けられている。すなわち、吸気孔45aは、仕切壁53aと側縁41aとの間に形成され、吸気孔45aの前方は、グリル扉40の中央方向が仕切壁53aによって、水平方向が手掛け部52によって、上方向がフランジ部51によって、それぞれ包囲(かかる包囲された空間を「とっ手空間59」と称す)され、下方のみが開口しているから、万一、グリル加熱室20の圧力が上昇して熱気が逆流し、吸気孔45から熱気が噴出した場合であっても、かかる熱気は下方に向かって流れ出し、調理者の手に熱気が触れることがない(吸気孔45bについても同じ)。
(Partition wall)
Further, partition walls 53a and 53b (hereinafter sometimes collectively referred to as “partition walls 53”) for connecting the rear surface of the handle 50 and the front plate 41 of the grill door 40 are provided near the grill door 40 side. It has been. That is, the air intake hole 45a is formed between the partition wall 53a and the side edge 41a, and the front side of the air intake hole 45a is directed upward by the partition wall 53a in the center direction of the grill door 40 and by the handle 52 in the horizontal direction. Are surrounded by the flange portion 51 (the enclosed space is referred to as a “hand space 59”), and only the lower part is opened. Therefore, in the unlikely event that the pressure in the grill heating chamber 20 rises, Even when the hot air flows backward and the hot air is ejected from the intake hole 45, the hot air flows downward and does not touch the cook's hand (the same applies to the intake hole 45b).

また、仕切壁53を設けたことによって、調理者が仕切壁53よりも側方に手(指に同じ)を掛けること、あるいは、手を側方に移動させることがさらに困難になっている。
なお、とっ手50は断面略L字状であるから、大きな断面二次モーメントを具備するものであるが、仕切壁53を設けたことによって、とっ手50の剛性がさらに大きくなっている。また、とっ手50(含む、仕切壁53)は表板41とは別途成形して表板41に設置しても、表板41と一体的に成形してもよい。
Further, the provision of the partition wall 53 makes it more difficult for the cook to place his / her hand (same as a finger) on the side of the partition wall 53 or to move the hand to the side.
Since the handle 50 has a substantially L-shaped cross section, the handle 50 has a large second moment of section. However, the provision of the partition wall 53 further increases the rigidity of the handle 50. The handle 50 (including the partition wall 53) may be formed separately from the front plate 41 and installed on the front plate 41, or may be formed integrally with the front plate 41.

(吹出孔)
図4において、グリル扉40の裏板42の側縁42a、42b寄りの範囲に、貫通する側方吹出孔46a、46b(以下まとめて「側方吹出孔46」と称する場合がある)と、裏板42の中央範囲に、貫通する中央吹出孔47と、が形成されている。
図4および図5において、側方吹出孔46は、表板41に形成された吸気孔45と同様に「側方寄り」に配置されているものの、吸気孔45とは上下方向で位相が一致していない(ズレている)。このため、吸気孔45を通過した吸気(空気)は、側方吹出孔46に直接侵入することはなく、裏板42に衝突してドアー空間49に充満した後、側方吹出孔46および中央吹出孔47からグリル加熱室20に吹き出すことになる。
(Blowout hole)
In FIG. 4, penetrating side blowing holes 46 a and 46 b (hereinafter sometimes collectively referred to as “side blowing holes 46”) in the range near the side edges 42 a and 42 b of the back plate 42 of the grill door 40, A central blowout hole 47 is formed in the center area of the back plate 42.
4 and 5, the side blowing holes 46 are arranged “sideward” in the same manner as the intake holes 45 formed in the front plate 41, but have the same phase in the vertical direction as the intake holes 45. I have n’t done it. For this reason, the intake air (air) that has passed through the intake holes 45 does not directly enter the side blow holes 46, collides with the back plate 42, fills the door space 49, and then the side blow holes 46 and the center. The air is blown out from the blowout hole 47 to the grill heating chamber 20.

このとき、中央吹出孔47の開口面積が側方吹出孔46の開口面積より大きくなっているから、吸気の吹き出しが吸気孔45に近い側方吹出孔46に集中することがない。したがって、吸気孔45から遠い中央吹出孔47からの吹き出し量が確保されるから、グリル加熱室20の全幅に渡って、比較的均一な風流れが形成され、被加熱物の均一な冷却が可能になる。
また、吸気がドアー空間49に充満するから、かかる吸気によって透明窓41wやとっ手50が冷却されることになる。
At this time, since the opening area of the central blowing hole 47 is larger than the opening area of the side blowing hole 46, the blowout of the intake air does not concentrate on the side blowing hole 46 close to the suction hole 45. Therefore, since the amount of blowout from the central blowout hole 47 far from the intake hole 45 is ensured, a relatively uniform wind flow is formed over the entire width of the grill heating chamber 20, and the object to be heated can be uniformly cooled. become.
Further, since the intake air fills the door space 49, the transparent window 41w and the handle 50 are cooled by the intake air.

なお、図4において、側方吹出孔46および中央吹出孔47はそれぞれ長穴であるが、本発明はその形状、数量さらに、配置の範囲をこれに限定するものではない。たとえば、それぞれを複数の丸孔によって構成してもよい。このとき、当該丸孔の単位面積当たりの形成数あるいは開口面積(丸孔の直径)を、中央吹出孔47の方が側方吹出孔46よりも、密にあるいは大きくしておけば、グリル加熱室20において全幅に渡る均一な風流れが形成される。
また、裏板42の全幅に渡って側方吹出孔46および中央吹出孔47を形成してもよい(このとき、側方吹出孔46および中央吹出孔47の境界が明確でなくなる)。このとき、かかる吹出孔の開口面積(丸孔のとき、その直径)を、裏板42の中央に近づく程大きく、あるいは、かかる吹出孔同士の間隔を中央に近づく程狭くしておけば、グリル加熱室20において全幅に渡る均一な風流れが形成される。
さらに、ドアー空間49に、風流れを誘導する誘導板(いわゆる「邪魔板」)やオリフィスを形成して、吹き出す空気の流れを均一にしてもよい。
In FIG. 4, the side outlet holes 46 and the central outlet hole 47 are elongated holes, but the present invention does not limit the shape, quantity, and arrangement range thereof. For example, each may be constituted by a plurality of round holes. At this time, if the number of the round holes formed per unit area or the opening area (diameter of the round hole) is set closer or larger in the central blowing hole 47 than in the side blowing hole 46, grill heating is performed. A uniform wind flow over the entire width is formed in the chamber 20.
Moreover, you may form the side blowing hole 46 and the center blowing hole 47 over the full width of the backplate 42 (At this time, the boundary of the side blowing hole 46 and the center blowing hole 47 becomes unclear). At this time, if the opening area of the blowout holes (the diameter of a round hole) is increased as it approaches the center of the back plate 42 or the interval between the blowout holes is reduced as it approaches the center, the grill A uniform wind flow over the entire width is formed in the heating chamber 20.
Further, a guide plate (so-called “baffle plate”) or an orifice for guiding the wind flow may be formed in the door space 49 to make the flow of the blown air uniform.

(シール用パッキン)
図4において、裏板42の外周にそって、矩形環状にシール用パッキン48が設置されている。シール用パッキン48はグリル扉40を後方に押し込んだ際、グリル加熱室の前方開口部21の周囲に気密的に当接するものであって、吸気孔45以外の個所から空気がグリル加熱室に侵入しないようにシールしている。
(Seal packing)
In FIG. 4, a seal packing 48 is installed in a rectangular ring shape along the outer periphery of the back plate 42. When the grill door 40 is pushed rearward, the seal packing 48 comes into airtight contact with the periphery of the front opening 21 of the grill heating chamber, and air enters the grill heating chamber from locations other than the intake holes 45. It is sealed so that it does not.

(とっ手のバリエーション)
図6は、本発明の実施形態に係る加熱調理器におけるとっ手のバリエーションを模式的に示す斜視図である。なお、図3と同じ部分または相当する部分にはこれと同じ符号を付し、一部の説明を省略する。
図6の(a)において、とっ手150は、とっ手50の手掛け部52の端部52bに、支持部152bが形成され、支持部152bの後方が表板41の側縁41bに設置(接続)されている。また、他方の端部である端部52aには支持部がなく、表板41の側縁41aに直接設置(接続)されている。そして、手掛け部52と表板41との間隔がより広い支持部152b側にのみ仕切壁53bが設置されている。
したがって、前面操作部11(図1参照)に、たとえば、意匠性を高めるための凸部を形成した場合、かかる凸部と、支持部152bの高さを揃えておけば、グリル扉40を閉じた際、とっ手150の手掛り52の前面と前記凸部の前面との段差が無くなり、意匠性が向上する。
なお、とっ手150には、フランジ部51と仕切壁53aが設置されていないが、何れかを選択的に設置してもよい。
(Variety of variations)
FIG. 6 is a perspective view schematically showing a variation of the handle in the heating cooker according to the embodiment of the present invention. Note that the same or corresponding parts as those in FIG.
6A, the handle 150 has a support portion 152b formed at the end 52b of the handle portion 52 of the handle 50, and the rear of the support portion 152b is installed (connected) on the side edge 41b of the front plate 41. ) Further, the end portion 52a which is the other end portion has no support portion and is directly installed (connected) to the side edge 41a of the front plate 41. And the partition wall 53b is installed only in the support part 152b side where the space | interval of the handle 52 and the surface board 41 is wider.
Therefore, for example, when a convex portion for improving the design is formed on the front operation portion 11 (see FIG. 1), the grill door 40 is closed if the convex portion and the height of the support portion 152b are aligned. In this case, the step difference between the front surface of the clue 52 of the handle 150 and the front surface of the convex portion is eliminated, and the design is improved.
In addition, although the flange part 51 and the partition wall 53a are not installed in the handle 150, either may be selectively installed.

図6の(b)において、とっ手250は、とっ手50の手掛け部52の幅を、グリル扉40の全幅と同じ幅とし、さらに、手掛け部52を仕切壁53a、53bによってグリル扉40の表板41に設置(接続)された平板にしたものである。
このとき、吸気孔45の前方は、上下方向および側方が開口されているから、その分、吸気抵抗が小さくなっている。なお、手掛け部52をアーチ状にしたり、フランジ部51を設置したりしてもよい。
In FIG. 6B, the handle 250 has a width of the handle 52 of the handle 50 that is the same as the entire width of the grill door 40, and the handle 52 is separated from the grill door 40 by the partition walls 53a and 53b. It is a flat plate installed (connected) to the front plate 41.
At this time, the front and rear sides of the intake hole 45 are open in the vertical direction and the side, and therefore the intake resistance is reduced accordingly. The handle portion 52 may be formed in an arch shape or the flange portion 51 may be installed.

図6の(c)において、とっ手350は、とっ手50の手掛け部52の幅を、グリル扉40の側方寄りの範囲を除く幅とし、手掛け部52の端部52a、52bに、支持部352a、352bが形成され、支持部352a、352bの後方が表板41に設置(接続)されている。すなわち、とっ手250の手掛け部52の幅を仕切壁53aと仕切壁53bとの距離に同じにし、仕切壁53a、53bを支持部352a、352bと読み替えたものに同じである。
このため、吸気孔45は前方から直接視認されるものの、吸気孔45の近くには前方に突出するとっ手350が設置されているから、仮に、調理者が加熱調理器100の前方の至近位置に接近したとしても、吸気孔45が塞がれることはない。
なお、手掛け部52を平面状にしたり、フランジ部51を設置したりしてもよい。
In FIG. 6C, the handle 350 has a width of the handle portion 52 of the handle 50 excluding the range near the side of the grill door 40 and is supported by the end portions 52a and 52b of the handle portion 52. The portions 352a and 352b are formed, and the rear portions of the support portions 352a and 352b are installed (connected) to the front plate 41. That is, the width of the handle portion 52 of the handle 250 is the same as the distance between the partition wall 53a and the partition wall 53b, and the partition walls 53a and 53b are the same as the support portions 352a and 352b.
For this reason, although the intake hole 45 is directly visible from the front, since the handle 350 is installed in the vicinity of the intake hole 45 so as to protrude forward, it is assumed that the cook is in the closest position in front of the heating cooker 100. Even if it approaches, the intake hole 45 will not be blocked.
The handle portion 52 may be flat or the flange portion 51 may be installed.

(グリル扉のバリエーション)
以上、理解を容易にするため、グリル扉40は表板41、裏板42等で形成され、とっ手50は表板41に設置(接続)されるものとして説明しているが、かかる構成部材(構成する部分に同じ)は、それぞれ別体のものであって、相互に接続されるものに限定されるものではない。
たとえば、裏板42と外周板43と内周板44とは、一体的に成形(たとえば、プレス成形)されることがある。また、とっ手50と表板41の一部(透明窓41wを含む範囲、あるいは、吸気孔45を含む範囲)とが一体的に形成されることがある。
さらに、グリル扉40の構成部材およびとっ手50を形成する材質や、これらを接続する場合には相互の接続要領は、限定するものではない。
(Grill door variations)
As described above, in order to facilitate understanding, the grill door 40 is described as being formed by the front plate 41, the back plate 42, and the like, and the handle 50 is installed (connected) to the front plate 41. (Same as the constituent parts) are different from each other, and are not limited to those connected to each other.
For example, the back plate 42, the outer peripheral plate 43, and the inner peripheral plate 44 may be integrally molded (for example, press molding). Further, the handle 50 and a part of the front plate 41 (a range including the transparent window 41w or a range including the intake hole 45) may be integrally formed.
Furthermore, the components forming the grill door 40 and the material forming the handle 50, and the connection procedure between them are not limited.

(加熱体のバリエーション)
また、加熱体72として、高周波数電流が流れるコイルであって、被加熱物を電磁誘導によって加熱するものを示しているが、本発明はこれに限定するものではなく、また、これを必須とするものではない。たとえば、加熱体72が、電熱ヒータやガスバーナ等であってもよい。このとき、加熱体の形式に応じて、天板70が撤去されたり、電源スイッチ73、74の形式が変動することになる。また、グリル加熱室20のみにおいて調理し、天面に加熱手段を具備しないものであってもよい。
さらに、グリル加熱室20には、上ヒータ23および下ヒータ24が配置されたものを示しているが、本発明はこれに限定するものではない。たとえば、上ヒータ23および下ヒータ24の一方のみが配置されたものであってもよい。なお、上ヒータ23および下ヒータ24は通電による発熱体(ニクロム線等)であっても、ガスバーナであってもよい。
(Variation of heating element)
Further, although the heating body 72 is a coil through which a high-frequency current flows and heats an object to be heated by electromagnetic induction, the present invention is not limited to this, and this is essential. Not what you want. For example, the heating body 72 may be an electric heater or a gas burner. At this time, the top plate 70 is removed or the types of the power switches 73 and 74 are changed according to the type of the heating body. Alternatively, cooking may be performed only in the grill heating chamber 20, and the top surface may not be provided with heating means.
Further, the grill heating chamber 20 is shown in which an upper heater 23 and a lower heater 24 are arranged, but the present invention is not limited to this. For example, only one of the upper heater 23 and the lower heater 24 may be disposed. The upper heater 23 and the lower heater 24 may be heating elements (such as nichrome wire) by energization or gas burners.

以上より、本発明の加熱調理器は、グリル加熱室に空気を吸引する吸気孔が塞がれることがなく、吸引した空気をグリル加熱室に分散して被加熱物の冷却ムラを防止することができるから、グリル加熱室を具備する各種加熱調理器に広く利用することができる。   As described above, the cooking device of the present invention prevents the air to be sucked into the grill heating chamber from being blocked, and the sucked air is dispersed in the grill heating chamber to prevent uneven cooling of the object to be heated. Therefore, it can be widely used in various cooking devices having a grill heating chamber.
