Description

本発明は、高周波加熱機器の安全性を確保しながらドアー開閉力を軽くするものである。   The present invention reduces the door opening and closing force while ensuring the safety of the high-frequency heating device.

従来、この種の横開きドアーはハンドル部を直接引っ張って開くプル方式を採用している（例えば、特許文献１参照）。   Conventionally, this type of side-opening door employs a pull system that opens by directly pulling the handle (see, for example, Patent Document 1).

図５は、特許文献１に記載された従来のプル式ドアー開閉機構を示すものである。図５に示すように、ドアー１と、ドアー１に設けたハンドル２と、ドアー１に設けたドアーキー３と、ドアーキーが係合するドアーフック４とドアーキー３によって作動されるフックスペーサー５、６と、フックスペーサーを介しＯＮーＯＦＦするスイッチ７、８、９から構成されている。
特開平１１−１８２８５３号公報 FIG. 5 shows a conventional pull-type door opening / closing mechanism described in Patent Document 1. In FIG. As shown in FIG. 5, the door 1, the handle 2 provided on the door 1, the door key 3 provided on the door 1, the door hook 4 engaged with the door key, the hook spacers 5 , 6 operated by the door key 3, It consists of switches 7, 8, and 9 that turn on and off via hook spacers.
Japanese Patent Laid-Open No. 11-182853

しかしながら、前記従来の構成では、ドアー１のハンドル２を引っ張るとドアーキー３先端係合部の傾斜角３ａに沿って開いていく。この傾斜角度がきついとドアー１の開力は重たくなり、ゆるいと軽くなるのは言うまでもない。この傾斜角度を決定する要因はドアー１の開閉力、電波漏洩規制であるが、ドアー１の開きに対して発振を停止するスイッチ６の動作を優先させているのが現状である。ドアーキー３はバネ１０の力でフックスペーサー５、６を介しスイッチ７、８、９をＯＮさせる構造にしている。ドアーキー３はドアー１に設けた取り付け部１１に摺動可能に取り付けられている。バネ１０はスイッチ７、８、９のＯＮ荷重とドアーキーの３の摺動抵抗を考慮した荷重設定が求められる。この条件でドアー１を開けようとすると、ドアーキー３とドアーフック４の係合部４ａの摩擦抵抗、ドアー１に設けた取り付け部１１とドアーキー３の摩擦抵抗とドアー１の開方向とドアーキー３の動作方向が直行しているため分力されかなり開力が重たくなってしまうという課題を有していた。 However, in the conventional configuration, when the handle 2 of the door 1 is pulled, the door key 3 opens along the inclination angle 3a of the front end engaging portion. Needless to say, when the inclination angle is tight, the opening force of the door 1 becomes heavy, and when it is loose, it becomes light. The factors that determine the inclination angle are the opening / closing force of the door 1 and the radio wave leakage regulation, but the current situation is that priority is given to the operation of the switch 6 that stops oscillation with respect to the opening of the door 1. The door key 3 has a structure in which the switches 7, 8 and 9 are turned on via the hook spacers 5 and 6 by the force of the spring 10. The door key 3 is slidably attached to an attachment portion 11 provided on the door 1. The spring 10 is required to have a load setting in consideration of the ON load of the switches 7 , 8 , 9 and the sliding resistance of the door key 3. If an attempt is made to open the door 1 under these conditions, the friction resistance of the engagement portion 4a of the door key 3 and the door hook 4, the friction resistance of the mounting portion 11 provided on the door 1 and the door key 3, the opening direction of the door 1, and the operation of the door key 3 Since the direction is perpendicular, there is a problem that the force is divided and the opening force becomes considerably heavy.

本発明は、前記従来の課題を解決するもので、電波漏洩に対して全く心配のない、誰でも指一本で簡単に開閉できる操作性に優れた機器を提供することを目的とする。   SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a device with excellent operability that anyone can easily open and close with one finger without worrying about radio wave leakage.

イッチのＯＮ荷重に対して余裕を持った引き込み力に設定してある。 1 to 4, the high-frequency heating device includes a main body 12, a heating chamber 13 for storing food, a door 1 that closes the heating chamber 13, and an operation unit 14, and the door 1 has a door key 3 for maintaining the closed state with the main body 12. However, the door hook 4 is provided on the main body 12 side. The door key 3 is hooked at one end to the upper portion 1a of the door 1 so as to act upward by a door spring 10 (spring), and the other end is hooked to the door key 3 so as to be slidable into the long hole 15a on the side surface of the sheet metal 15 having the function of preventing radio wave leakage. It is caught. The door spring 10 turns on the switch 9 while receiving the friction resistance between the tip of the projection 3b (convex portion) of the door key 3 and the hook spacer 5, and the contact resistance between the door key 3 and the side surface of the metal plate 15 having the function of preventing leakage of radio waves ( (ON load 200g) is necessary, so the pull-in force has a margin with respect to the ON load of the switch.

ドアーキー３は板金１５との間で摺動する。ドアー１の下部にはハンドル２がハンドル２の支点２ａを中心に回動するよう取り付けてあり、ハンドルバネ１６によって上方に作用するように一端をドアー１の爪１ｂに、他端をハンドル２に引っ掛けてある。またハンドル２の手掛かり部２ｂと支点２ａを結ぶ直線から略９０℃の位置に突起２ｃが設けてある。   The door key 3 slides between the sheet metal 15. A handle 2 is attached to the lower part of the door 1 so as to rotate about a fulcrum 2 a of the handle 2. One end is connected to the claw 1 b of the door 1 and the other end is connected to the handle 2 so as to act upward by a handle spring 16. It is caught. Further, a protrusion 2c is provided at a position of approximately 90 ° C. from a straight line connecting the clue portion 2b of the handle 2 and the fulcrum 2a.

一方、ドアーキー３にはハンドル２の突起２ｃを覆うように凹部があり、突起２ｃの動作方向に近接して接触面３ａを有している。またドアーキー３にはドアーフック４側に向け２個の突起部３ｂ、３ｃ（凸部）がドアー１に中央から略均等に設けてあり先端には上向きの嵌合部を有している。この嵌合部はドアーキー３の上下方向の摺動と略平行に突出させている。 On the other hand, the door key 3 has a recess so as to cover the protrusion 2c of the handle 2, and has a contact surface 3a close to the operation direction of the protrusion 2c. Also the Doaki 3 in two projections 3b, 3c (convex portions) is provided with substantially uniformly from the center to the door 1 tip toward the Doafukku 4 side has an upward fitting portion. The fitting portion is substantially not parallel to the projecting sliding in the vertical direction of Doaki 3.

本体１２側に配置されたドアーフック４にはドアーキー３の嵌合部に対応する位置になだらかな傾斜を持った開口４ｂ、４ｃを設けてある。ドアーフック４にはドアー１の開閉を検知するスイッチ７，８，９が取り付けてあり、スイッチ７，８はフックスペーサー５を介しドアーキー３の突起部３ｂの先端、スイッチ９はドアーキー３の突起部３ｃの先端に設けた嵌合部の先端で直接ＯＮ・ＯＦＦする構成としている。スックスペーサー５は支点５ａを回転軸とし、一片をドアーキー３の突起部３ｂの先端で押し、他端でスイッチ８をＯＮさせる。支点５ａとドアーキー３の突起部３ｂが接触する一片までの距離を支点５ａからスイッチ８をＯＮさせる他端の距離の２倍程度取ってある。スイッチ７の動作用ボタンはスペーサー５の支点５ａに向けて取り付けてある。 The Doafukku 4 disposed on the body 12 side opening 4b having a gentle slope at a position corresponding to the fitting portion of Doaki 3, is provided with 4c. The door hook 4 is provided with switches 7, 8, 9 for detecting the opening / closing of the door 1. The switches 7, 8 are connected to the tip of the projection 3 b of the door key 3 through the hook spacer 5, and the switch 9 is the projection 3 c of the door key 3. It is configured to oN · OFF directly at the tip of the engagement portion fitted provided on the tip. The sock spacer 5 has a fulcrum 5a as a rotation shaft, one piece is pushed at the tip of the projection 3b of the door key 3, and the switch 8 is turned on at the other end. The distance from the fulcrum 5a to the one piece where the projection 3b of the door key 3 contacts is about twice the distance from the fulcrum 5a to the other end where the switch 8 is turned on. The operation button of the switch 7 is attached toward the fulcrum 5 a of the spacer 5.

本体１２へのドアーフック４の取り付けはドアー１のガタ等が発生しないようビスにより調整して取り付ける構成（図示せず）としている。   The door hook 4 is attached to the main body 12 with a structure (not shown) that is adjusted and attached with a screw so as not to cause looseness of the door 1 or the like.

以上のように構成された高周波加熱機器のドアー開閉装置について、以下その動作、作用を説明する。   About the door opening / closing apparatus of the high frequency heating apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

まず、ドアー１の閉じた状態ではハンドル２はハンドルバネ１６によって上方に作用するようにしてあり常に所定の位置にガタ等の発生もなく安定して取り付けることが出来る。またハンドル２の突起２ｃとドアーキー３の接触面３ａ間に隙間を持たしているため多少の部品・組み立てバラツキは吸収できる構成としている。   First, when the door 1 is closed, the handle 2 is acted upward by the handle spring 16 and can be stably attached to a predetermined position without any play. In addition, since there is a gap between the projection 2c of the handle 2 and the contact surface 3a of the door key 3, some components and assembly variations can be absorbed.

次に、ハンドル２の手掛かり部２ｂに手を掛け引っ張ると支点２ａを回転軸としハンドル２の突起２ｃ部が可動し、ハンドル２の突起２ｃでドアーキー３の接触面３ａを下方に押し下げる。   Next, when the hand 2 is pulled by the handle 2b of the handle 2, the protrusion 2c of the handle 2 moves with the fulcrum 2a as the rotation axis, and the contact surface 3a of the door key 3 is pushed downward by the protrusion 2c of the handle 2.

さらに、ハンドル２を引っ張り続けると、スイッチ９の動作ボタンがＯＦＦするがこの時ドアーフック４のドアーキー３の嵌合部に対応する位置になだらかな傾斜を持った開口４ｂ、４ｃからドアーキー３の突起部３ｂ、３ｃ先端の上向きの嵌合部は外れていない。またこの嵌合部はドアーキー３の上下方向の摺動と略平行に突出させているのでスイッチ９がＯＦＦした時点ではドアー１は全く開いていないこととなる。従って、高周波加熱機器が動作中でドアー１が少しでも開いた時にはすでに高周波の発振が停止していることとなる。さらにハンドル２を引っ張り続けると、ドアーフック４のドアーキー３の嵌合部に対応する位置になだらかな傾斜を持った開口４ｂ、４ｃからドアーキー３の突起部３ｂ、３ｃ先端の上向きの嵌合部が外れ、ドアー１を開くことが出来る。 Moreover, continued pulling of the handle 2, the operation button switch 9 is OFF although protrusion Doaki 3 from the opening 4b, 4c with a gentle slope at a position corresponding to the fitting portion of Doaki 3 at this time Doafukku 4 3b, the upward fitting portion of 3c tip does not come off. Also this fitting portion so that the door 1 is not at all open at the time since then substantially parallel to the projecting sliding in the vertical direction of Doaki 3 the switch 9 is turn OFF. Therefore, when the high frequency heating apparatus is in operation and the door 1 is opened even a little, the high frequency oscillation has already stopped. Continuing further pulling the handle 2, an opening 4b having a gentle slope at a position corresponding to the fitting portion of Doaki 3 Doafukku 4, the protrusion 3b of Doaki 3 from 4c, out upward fitting portion 3c tip , Door 1 can be opened.

以上のように、本実施の形態においては、ドアー開閉装置のドアーフック４に固定した
複数個のスイッチ７、８、９を、ドアーキー３の一部で直接・間接的にＯＮ・ＯＦＦさせる構成とし、ドアーフック４に固定された少なくとも１個以上のスイッチ７、８、９はドアー１と本体１２が保持された状態でＯＮ・ＯＦＦし、ドアーキー３のドアーフック４との係合は上下方向の摺動と略平行になるように設けることにより、発振が停止した状態ではドアー１は全く開くことがないため、ドアー１開時電波漏洩の心配のない安全な機器を提供できる。 As described above, in the present embodiment, the plurality of switches 7, 8, 9 fixed to the door hook 4 of the door opening / closing device are configured to be directly / indirectly turned on / off by a part of the door key 3, At least one of the switches 7, 8, 9 fixed to the door hook 4 is turned ON / OFF while the door 1 and the main body 12 are held, and the door key 3 is engaged with the door hook 4 by sliding in the vertical direction. By providing them so as to be substantially parallel, the door 1 does not open at all in a state where the oscillation is stopped. Therefore, it is possible to provide a safe device that does not have to worry about leakage of radio waves when the door 1 is opened.

以上のように、本発明にかかる高周波加熱機器のドアー開閉装置は、非常に軽い力で簡単にドアーの開閉が可能となるので、電熱加熱付高周波加熱装置にも適用できる。   As described above, the door opening and closing device of the high-frequency heating device according to the present invention can be easily opened and closed with a very light force, and thus can be applied to a high-frequency heating device with electric heating.
