本考案は、ターンテーブルを備えた電子レンジである高
周波加熱装置に関する。[Detailed Description of the Invention] The present invention relates to a high frequency heating device which is a microwave oven equipped with a turntable.
従来より用いられる電子レンジは第1図に示すように形
成される。A conventionally used microwave oven is formed as shown in FIG.
すなわち装置本体1に、開口部に扉体2を枢着する加熱
室3が設けられる。That is, the apparatus main body 1 is provided with a heating chamber 3 in which a door body 2 is pivotally attached to an opening.
加熱室3には図示しないマグネトロンから高周波を発振
し、収容する被加熱物aを加熱調理できるようになって
いるろ被加熱物aはターンテーブル4に載置され、加熱
中は回転して高周波を均等に吸収する。In the heating chamber 3, a magnetron (not shown) oscillates high frequency waves to heat and cook the stored object a.The object to be heated a is placed on a turntable 4, and during heating, it rotates and generates high frequency waves. absorbs evenly.
ターンテーブル4は駆動モータ5に駆動され回転するが
、これらの連結構造を第2図に示す。The turntable 4 is driven and rotated by a drive motor 5, and the connection structure thereof is shown in FIG.
加熱室3の底面には取付孔3aが穿設され、凹状に加工
した取付カップ6が螺着される。A mounting hole 3a is formed in the bottom surface of the heating chamber 3, into which a mounting cup 6 machined into a concave shape is screwed.
駆動モータ5は加熱室3にスペーサト・・を介して取付
けられる支持板8に固定され、その回転軸5aは上記取
付カップ6に穿設される透孔9に挿通ずる。The drive motor 5 is fixed to a support plate 8 attached to the heating chamber 3 via a spacer, and its rotating shaft 5a is inserted into a through hole 9 formed in the mounting cup 6.
上記回転軸5aにはターンテーブル4を載設する伝達シ
ャフト10が軸方向に移動自在で、かつ周方向に係合す
るように嵌合する。A transmission shaft 10 on which the turntable 4 is mounted is fitted onto the rotating shaft 5a so as to be movable in the axial direction and engaged in the circumferential direction.
したがって伝達シャフト10は加熱室3から回転軸5a
に容易に着脱可能であるとともに駆動モータ5により回
転されることとなる。Therefore, the transmission shaft 10 is connected from the heating chamber 3 to the rotating shaft 5a.
It can be easily attached and detached and is rotated by the drive motor 5.
伝達シャフト10と加熱室3との間にはスペーサ11が
介在する。A spacer 11 is interposed between the transmission shaft 10 and the heating chamber 3.
このスペーサ11は、耐高周波性で、高滑性体であるテ
フロン材などが用いられ、カップ6内に汁等が侵入する
のを防止するとともに透孔9からの電波漏洩を防止する
。The spacer 11 is made of a Teflon material that is resistant to high frequencies and highly slippery, and prevents juice and the like from entering the cup 6 and also prevents leakage of radio waves from the through hole 9.
本来スペーサ11は伝達シャフト10と同時成形すべき
であるが、材質的な事情から別体となっている。Originally, the spacer 11 should be molded at the same time as the transmission shaft 10, but due to material considerations, it is made separately.
ところでスペーサ11は第3図に示すようにAφの内孔
11aが設けられ、伝達シャフト10のBφのシャフト
部10aに遊嵌する。By the way, as shown in FIG. 3, the spacer 11 is provided with an Aφ inner hole 11a, and loosely fits into the Bφ shaft portion 10a of the transmission shaft 10.
このため、加熱室3の掃除の際など伝達シャフト10を
回転軸5aを抜出すと、Bφ〉Aφのためスペーサ11
が残ってしまう。Therefore, when the rotating shaft 5a of the transmission shaft 10 is pulled out when cleaning the heating chamber 3, etc., the spacer 11
remains.
したがってスペーサ11が紛失したり、伝達シャフト1
0を回転軸5aに嵌合する際にスペーサ11との穴合せ
が必要であり、面倒であるとともに入れ忘れることもあ
る。Therefore, the spacer 11 may be lost or the transmission shaft 1 may be lost.
0 to the rotating shaft 5a, it is necessary to align the holes with the spacer 11, which is troublesome and may be forgotten.
本考案は上記事情にもとづきなされたものであり、その
目的とするところは、比較的簡単な構造でありながらス
ペーサの管理を容易化するとともに組立作業の単純化を
図った高周波加熱装置を提供しようとするものである。The present invention was developed based on the above circumstances, and its purpose is to provide a high-frequency heating device that has a relatively simple structure, facilitates spacer management, and simplifies assembly work. That is.
以下本考案の一実施例を説明するに、伝達シャフトを除
く形状は第1図および第2図と同様であるので説明を省
略する。An embodiment of the present invention will be described below. Since the shape except for the transmission shaft is the same as that shown in FIGS. 1 and 2, the explanation will be omitted.
そして伝達シャフトの一実施例は第4図および第5図に
もとづいて説明する。One embodiment of the transmission shaft will be explained based on FIGS. 4 and 5.
すなわち伝達シャフト10のシャフト部10aには掛合
部であるところの一対の掛合突起12.12が突設され
る。That is, the shaft portion 10a of the transmission shaft 10 is provided with a pair of engaging projections 12, 12, which are engaging portions.
これら掛合突起12゜12はできるだけ相対向する位置
に設けるのが望ましく、その両端間隔をC寸法に設定す
る。It is desirable that these engaging protrusions 12.degree. 12 are provided at positions facing each other as much as possible, and the distance between both ends thereof is set to dimension C.
装置の組立時、スペーサ11の内孔Aφに対して伝達シ
ャフト10のシャフト部10aの外径寸法BφはAφ〉
Bφであるところから、スペーサ11はシャフト部10
a下端から嵌挿できる。When assembling the device, the outer diameter Bφ of the shaft portion 10a of the transmission shaft 10 with respect to the inner hole Aφ of the spacer 11 is Aφ>
Since Bφ, the spacer 11 is connected to the shaft portion 10.
a Can be inserted from the bottom end.
しかるにC>Aφであるのでスペーサ11は掛合突起1
2゜12に引掛かり、それ以上には嵌挿し難い。However, since C>Aφ, the spacer 11 is the engaging protrusion 1.
It gets stuck at 2°12 and is difficult to insert beyond that.
ところがこのスペーサ11は弾性があるので、強制的に
嵌挿することにより掛合突起12.12を乗越えて図に
示す状態となる。However, since this spacer 11 has elasticity, when it is forcibly inserted, it gets over the engaging protrusions 12 and 12, resulting in the state shown in the figure.
しかして伝達シャフト10がどの位置にあってもスペー
サ11が必ずシャフト部10aに嵌合して強制的に外さ
ないかぎり外れない。Therefore, no matter where the transmission shaft 10 is located, the spacer 11 is always fitted into the shaft portion 10a and cannot be removed unless it is forcibly removed.
このため伝達シャフト10が加熱室3にあるときは、シ
ャフト10と加熱室3底面間にスペーサ11が介在しシ
ャフト10の回転を円滑化するとともに相互の摩耗を防
止する。Therefore, when the transmission shaft 10 is in the heating chamber 3, the spacer 11 is interposed between the shaft 10 and the bottom surface of the heating chamber 3 to smooth the rotation of the shaft 10 and prevent mutual wear.
さらにスペーサ11はカップ6内に煮汁等が侵入するの
を防止するとともに透孔9から電波が漏洩するのを防止
する。Furthermore, the spacer 11 prevents broth etc. from entering the cup 6 and also prevents radio waves from leaking from the through hole 9.
また加熱室3内の掃除の際などターンテーブル4および
伝達シャフト10を取外せば、スペーサ11は伝達シャ
フト10の掛合突起12゜12に掛合したまま加熱室3
から取除かれる。Furthermore, if the turntable 4 and the transmission shaft 10 are removed when cleaning the inside of the heating chamber 3, the spacer 11 remains engaged with the engaging protrusion 12 of the transmission shaft 10 and is removed from the heating chamber 3.
removed from.
したがってスペーサ11が加熱室3に取残されることが
なく掃除が容易である。Therefore, the spacer 11 is not left behind in the heating chamber 3, and cleaning is easy.
伝達シャフト10を再び回転軸5aに嵌合すれば、スペ
ーサ11は同時に元の状態になって組立てられる。When the transmission shaft 10 is fitted onto the rotating shaft 5a again, the spacer 11 is returned to its original state at the same time and assembled.
なお掛合部12は第4図および第5図に示される形状ば
かりでなく、たとえば第6図および第1図にしても良い
。The shape of the engaging portion 12 is not limited to that shown in FIGS. 4 and 5, but may also be formed, for example, in FIGS. 6 and 1.
すなわちシャフト部10aに平行に切落した掛合溝12
′を設ける。In other words, the engaging groove 12 is cut parallel to the shaft portion 10a.
′ is provided.
スペーサ11にも掛合溝12′に嵌合する内孔14を設
ける。The spacer 11 is also provided with an inner hole 14 that fits into the engaging groove 12'.
しかしながらシャフト部10の直径はスペーサ11の内
孔14最小径より大であり(Bφ>A)、挿入し難いが
弾性を利用して強制的に変形し、強制的に掛合溝12′
に嵌挿する。However, the diameter of the shaft portion 10 is larger than the minimum diameter of the inner hole 14 of the spacer 11 (Bφ>A), and although it is difficult to insert it, it is forcibly deformed using its elasticity, and the engaging groove 12' is forcibly deformed.
Insert into.
しかして上記実施例と同様の作用効果を得る。Thus, the same effects as in the above embodiment are obtained.
このように掛合部の形状は限定されるものではなく、要
は伝達シャフト10を回転軸5aから抜出したときのみ
スペーサ11を掛合できれば良い。As described above, the shape of the engaging portion is not limited, and it is sufficient that the spacer 11 can be engaged only when the transmission shaft 10 is extracted from the rotating shaft 5a.
なお取付カップ6は加熱室3底面と別体としたがこれに
限定されるものではなく、一体であっても良い。Although the mounting cup 6 is separate from the bottom surface of the heating chamber 3, the present invention is not limited thereto, and may be integrated.
以上説明したように本考案によれば加熱室の底面に駆動

ペーサとでは材質、形状が別体であるにも拘らず一体的
となり、スペーサの紛失を防止できるとともに組立作業
が容易化するなどの効果を奏する。As explained above, according to the present invention, a through hole is formed in the bottom of the heating chamber through which the rotating shaft of the drive motor projects, and a transmission shaft having a turntable is removably fitted to the rotating shaft, and the transmission Since an engaging part is provided on the shaft and the spacer interposed between the transmission shaft and the bottom of the heating chamber is engaged only when the transmission shaft is removed, the materials and shapes of the transmission shaft and spacer are different. Nevertheless, it is integrated, which has the effect of preventing loss of the spacer and facilitating assembly work.
