品で構成することにより、安全で耐久性の良い電子レン
ジを提供することができる。In the unlikely event that a fire occurs inside the microwave oven, the flames will
The operation panel and opening/closing buttons must be made of self-extinguishing resin to prevent them from coming out, but this resin has a high coefficient of friction and is somewhat less durable. Therefore, by configuring the opening/closing lever with two parts: a self-extinguishing resin and a resin with a low coefficient of friction, it is possible to provide a safe and durable microwave oven.
実施例
第１図は１つの部品で構成した開閉レバー１０の要部断
面図である。Embodiment FIG. 1 is a sectional view of a main part of an opening/closing lever 10 constructed of one component.
第１図において操作パネル３はポリスエニレンオキサイ
ドなどの自己消火性の樹脂で作られている。In FIG. 1, the operation panel 3 is made of self-extinguishing resin such as polyenylene oxide.
開閉レバー９は操作パネル３と同一材料で樹脂成形され
ている。開閉レバー９０回転軸は、操作パネル３を軸受
けとして回動するようになっている。The opening/closing lever 9 is resin molded from the same material as the operation panel 3. The rotation shaft of the opening/closing lever 90 is configured to rotate using the operation panel 3 as a bearing.
開閉レバー９には細い板バネ１４が設けられており開閉
レバー９を矢印の方向に押すと、回転軸１６を中心に回
転し板バネ１４の先端は操作パネル３の裏面に当たって
いるので弾性限界内でたわむことになる。したがって第
４図のバネ１３の役目を果す。The opening/closing lever 9 is equipped with a thin leaf spring 14. When the opening/closing lever 9 is pushed in the direction of the arrow, it rotates around the rotating shaft 16 and the tip of the leaf spring 14 hits the back of the operation panel 3, so it is within the elastic limit. It will sag. Therefore, it plays the role of the spring 13 in FIG.
第２図は第１図のＡ−Ａ’断面図である。開閉レバー９

れらの部品の組立てるのに要する時間は極めて少い。FIG. 3 is a sectional view of a main part of another embodiment of the present invention. For markets such as the United States, flame-retardant resin materials are required when the exterior of the main body 1 consists of only the operation panel 3 and opening/closing buttons 4, but this material generally has low mechanical strength and poor elasticity. Therefore, by configuring the opening/closing lever 9 for opening the door 2 and the opening/closing button 4 as two parts, the above-mentioned drawbacks can be overcome. In FIG. 3, the opening/closing lever 9 is made of a resin such as polyacetal which has a small coefficient of friction and is rich in elasticity, and has a function of moving the lever 8%O and a leaf spring 14. The open/close button 4 is made of self-extinguishing resin, and is made of a material that will not cause flames to escape even if a fire occurs inside the main body. The opening/closing button 4 is provided with a rotation shaft 16 for rotating the opening/closing button 4. The flange 16 having the rotating shaft 15 has a certain length so as to be able to bounce inward, and is attached to the operation panel while sliding on an inclined portion 17 provided on the operation panel 3. Therefore, the time required to assemble these parts is extremely small.
第４図は第３図の断面図である。バネ１４はシャーシー
１８と接触して開閉ボタンのバネ性を有する様になって
いる。FIG. 4 is a sectional view of FIG. 3. The spring 14 comes into contact with the chassis 18 and has the spring properties of an opening/closing button.
発明の効果 以上のように本発明には以下のような効果がある。Effect of the invention As described above, the present invention has the following effects.
（１） ドア開閉機構の為に構成する部品点数が少く
なるのでコストダウンがはかれる。(1) Costs can be reduced because the number of parts required for the door opening/closing mechanism is reduced.
（２）部品点数が少なく、弾性力で組み立てる構成の為
組立工数が大巾に削減される。(2) Since the number of parts is small and the structure is assembled using elastic force, the number of assembly steps is greatly reduced.
（３）樹脂成形部品で構成しているので板金の折り曲げ
で構成するよりも寸法のバラツキが少ないので量産した
場合、ドアが開きにくいなどの不良が全くなくなる。(3) Since it is constructed from resin molded parts, there is less variation in dimensions than when it is constructed by bending sheet metal, so when mass-produced, there will be no defects such as doors that are difficult to open.
（４）機能に合った樹脂材料を選べるのでドアを開ける
為の操作力も非常に少くなる。(4) Since you can choose a resin material that matches the function, the operating force required to open the door is extremely small.
