It is. FIG. 4 is a diagram showing a resistance region of the damper when the door of the cooker is opened and closed, and FIG. 5 is a drag characteristic diagram with respect to the stroke of the damper of the cooker.

本発明の特徴は、加熱室２内の被加熱物３を出し入れする扉５の開閉動作において、扉４を閉じる前と、扉４を開いて終端部に到達する前に、衝撃力を緩衝するダンパーを構成することである。 The feature of the present invention is that the impact force is buffered before the door 4 is closed and before the door 4 is opened and reaches the terminal end in the opening / closing operation of the door 5 for taking in and out the article 3 to be heated in and out of the heating chamber 2. It is to configure a damper.

以下、実施例に従い詳細に説明する。 Hereinafter, it demonstrates in detail according to an Example.

図１ないし図３において、調理器１は内部配置する加熱室２の中に電熱や高周波で加熱される被加熱物３を載置し、加熱室２の開口部に装着した扉４の開閉によって、被加熱物３の出し入れを行う構成としている。そして、扉４は扉４に支点を持つドアアーム５と、調理器１側に固定、係止されたドアガイドローラ６、ドアバネ７の付勢によりヒンジ８を支点として開閉自在に装着されている。また、調理器１の外装と加熱室２の空間には高周波発振器や、ヒータ、制御基板等の各種の電気部品９が配置されている。 In FIG. 1 thru | or FIG. 3, the cooking device 1 mounts the to-be-heated material 3 heated by an electric heating or a high frequency in the heating chamber 2 arrange | positioned inside, and opens and closes the door 4 with which the opening part of the heating chamber 2 was mounted | worn. In this configuration, the object to be heated 3 is taken in and out. The door 4 is mounted so as to be openable and closable with a hinge 8 as a fulcrum by urging a door arm 5 having a fulcrum on the door 4, a door guide roller 6 fixed and locked to the cooker 1 side, and a door spring 7. In addition, various electric components 9 such as a high-frequency oscillator, a heater, and a control board are arranged in the exterior of the cooking device 1 and the space of the heating chamber 2.

次に本発明の要部である扉４とダンパー１０の関連動作を説明する。扉４を閉じる時は図１に示す通り、ドアバネ７等により付勢された扉４の慣性衝撃荷重Ｐ１は調理器１側の支点A１１で回動する作動レバー１２の凸部１３を押して矢印ａ方向の動きでダンパー１０に伝達されダンパー１０の緩衝効果で消失される構成である。ダンパー１０は緩衝条件により、オイル、エアー、グリス、摩擦方式など各種存在する。なお、今回のダンパー１０はダンパー１０に対する荷重が開放された時には元の状態に復帰するための復帰バネ１４が内蔵されている必要がある。 Next, a related operation of the door 4 and the damper 10 which is a main part of the present invention will be described. When the door 4 is closed, as shown in FIG. 1, the inertial impact load P1 of the door 4 urged by the door spring 7 or the like pushes the convex portion 13 of the operating lever 12 that rotates at the fulcrum A11 on the cooker 1 side, and the arrow a It is the structure which is transmitted to the damper 10 by the movement of the direction and disappears by the buffering effect of the damper 10. There are various types of dampers 10 such as oil, air, grease, and a friction system depending on buffer conditions. The damper 10 this time needs to incorporate a return spring 14 for returning to the original state when the load on the damper 10 is released.

また、扉４を開ける時は図２で示すように、のぞき窓ガラス１５等の重量物を内蔵する扉４の自重による慣性衝撃荷重Ｐ２は扉４の動きと連動するドアアーム５に固定されたストッパーピン１６の動きにより、連結レバー１８を矢印ｂで示す開口側へ押す。すると支点Ｂ１７の働きで連結レバー１８の上部は開口と反対側の矢印ｃ方向へ回動する。そして、連結レバー１８の動きに連動して作動レバー１２の凸部が矢印ｄで示すダンパー１０方向に動き、ダンパー１０伝達されて慣性衝撃荷重Ｐ２は消失する構成である。 When the door 4 is opened, as shown in FIG. 2, the inertial impact load P <b> 2 due to the dead weight of the door 4 containing a heavy object such as the observation window glass 15 is fixed to the door arm 5 interlocked with the movement of the door 4. The movement of the pin 16 pushes the connecting lever 18 to the opening side indicated by the arrow b. Then, the upper part of the connecting lever 18 rotates in the direction of the arrow c on the side opposite to the opening by the function of the fulcrum B17. Then, the projection of the operating lever 12 moves in the direction of the damper 10 indicated by the arrow d in conjunction with the movement of the connecting lever 18, and is transmitted to the damper 10 so that the inertial impact load P2 disappears.

ダンパー抗力を作動させるタイミングは限定されるものではなくいつ作動させてもよい。だだし、最初から作動させると扉の開閉時に重たく違和感を感じ、開閉に時間を要してしまう。また、扉を閉じる直前あるいは、開く直前のダンパー抗力を作動させてもよいが、あまり直前だとダンパーまたは組立時のバラツキによりうまく作動しない場合がある。従って、ダンパー抗力を作動させる実用的なタイミングとしては扉が閉時終端部から１〜３０＃の角度の時、また、開時終端部から１〜３０＃の角度の時がよい。 The timing for activating the damper drag is not limited and may be activated at any time. However, when it is operated from the beginning, it feels awkward when opening and closing the door, and it takes time to open and close. Also, the damper drag just before the door is closed or just before the door may be operated, but if it is just before the door, it may not work well due to variations in the damper or assembly. Therefore, a practical timing for operating the damper drag is preferably when the door is at an angle of 1-30 # from the closing end and at an angle of 1-30 # from the opening end.

以下、扉４の動きと、ダンパー１０の作動範囲の一例を図４で説明する。扉４を閉じる時は、扉４が閉時終端部から１〜３０＃の角度からダンパー１０を作動させダンパー１０の抗力により扉４の慣性衝撃荷重Ｐ１を受け、同じく扉４を開いた時には、扉４が開時終端部から１〜３０＃の角度からダンパー１０を作動させダンパー１０の抗力により扉４の慣性衝撃荷重Ｐ２を受け衝撃力を消失させている。 Hereinafter, an example of the movement of the door 4 and an operation range of the damper 10 will be described with reference to FIG. When the door 4 is closed, the damper 4 is operated from an angle of 1 to 30 # from the terminal end when the door 4 is closed, receives the inertial impact load P1 of the door 4 by the resistance of the damper 10, and when the door 4 is also opened, When the door 4 is opened, the damper 10 is operated from an angle of 1 to 30 # from the end portion, and the inertial impact load P2 of the door 4 is received by the resistance of the damper 10 so that the impact force disappears.

次に、ダンパー１０の特性は図５で示すように、ダンパー１０の抗力はストロークの最初の段階で強く働くタイプＡ、最初は弱くストロークが増すとともに抗力が強くなるタイプＢ、ストロークの変化に対し平均的な抗力を保つタイプＣと各種存在する。本発明は上
記ダンパー構成のなかで扉４と作動レバー１２を介してダンパー１０の接合時の瞬間的衝撃荷重を緩和し、スムーズに扉の開閉をさせるためタイプＢ、タイプＣを採用している。通常、タイプＡはダンパーのシリンダーを単孔オリフィス構造、タイプＢ、タイプＣは複合オリフィス構造や揺動式などがある。 Next, as shown in FIG. 5, the characteristic of the damper 10 is that the resistance of the damper 10 is strong at the first stage of the stroke, type A is weak at first, the type B is weak, and the resistance increases as the stroke increases. There are various types, such as Type C, that maintain average drag. The present invention employs Type B and Type C in the above damper configuration in order to relieve the momentary impact load when the damper 10 is joined via the door 4 and the operating lever 12 and smoothly open and close the door. . Normally, type A has a single-hole orifice structure for the damper cylinder, and type B and type C have a composite orifice structure and a swing type.

以上のように、本発明によれば、扉の開閉時に生じる調理器への衝撃は消失し、液状の食品がこぼれたり、電気部品が振動で不良をおこすことがなくなるものである。 As described above, according to the present invention, the impact on the cooker that occurs when the door is opened and closed disappears, and liquid food is not spilled or electrical components do not fail due to vibration.
