作ることを目的とするものである。[Detailed description of the invention] The present invention relates to a heating chamber of a cooking appliance that has a rotary mounting table on the bottom of the heating chamber.In particular, the heating chamber of a high-frequency heating device in which a rotary mounting table is put into practical use can be made clean, bright, and economical. The purpose is to create a

一般に磁気結合手段により回転載置台を駆動する場合、
磁気による回転力伝達部の加熱室の材質はアルミＳＵＳ
３０４等の磁石を吸着しない非強磁性金属板を使用し
なければならないが、これ等の非強磁性金属板は明るく
て清潔感があるように塗装を施こそうとした場合塗装被
覆との密着性が鉄板に比して弱く、長年使用すると塗装
被膜がはがれる危険性があり、実用化できなかった。Generally, when a rotating mounting table is driven by magnetic coupling means,
The material of the heating chamber of the magnetic rotational force transmission section is aluminum SUS.
It is necessary to use a non-ferromagnetic metal plate such as 304 that does not attract magnets, but these non-ferromagnetic metal plates have poor adhesion to the paint coating when painting to give a bright and clean look. It was weaker than iron plate, and there was a risk that the paint film would peel off after long-term use, so it could not be put to practical use.

そこで本考案は上記塗装被膜のはがれる危険性をなくす
ることを目的とするもので、以下本考案の一実施例につ
いて添付図面とともに説明する。Therefore, the present invention aims to eliminate the risk of the paint film peeling off, and one embodiment of the present invention will be described below with reference to the accompanying drawings.

is a decorative board equipped with a time switch (not shown) and the like.

５は加熱室で、その底壁板６上には回転台７が配設され
、また内部上方には天板８とスタラーファン９が配設さ
れ、さらに外部上面には高周波発振器１０が配設されて
いる。Reference numeral 5 denotes a heating chamber, in which a rotary table 7 is arranged on a bottom wall plate 6, a top plate 8 and a stirrer fan 9 are arranged above the interior, and a high frequency oscillator 10 is arranged on the outer upper surface. It is set up.

ところで、前記回転台７の下面にはその外周縁部に複数
のローラ１１を配設しローラの内方には複数の磁石１２
とが円周状に配設されており、そのローラ１１によって
この回転台７は加熱室５の底壁板６に回転自在に載置さ
れている。By the way, a plurality of rollers 11 are arranged on the outer peripheral edge of the lower surface of the rotary table 7, and a plurality of magnets 12 are arranged inside the rollers.
are arranged in a circumferential manner, and the rotary table 7 is rotatably placed on the bottom wall plate 6 of the heating chamber 5 by the rollers 11 thereof.

また、この回転台７と対向して前記加熱室５の底壁板６
下には回転板１３が配設されている。In addition, a bottom wall plate 6 of the heating chamber 5 faces the rotary table 7.
A rotary plate 13 is arranged below.

この回転板１３は回転軸１３ａに軸支されたプーリで構
成されており、その上面には回転台７に装着された磁石
１２に対応する位置に複数の磁石１４が円周状に配設さ
れている。The rotating plate 13 is composed of a pulley supported by a rotating shaft 13a, and a plurality of magnets 14 are circumferentially arranged on the upper surface of the rotating plate 13 at positions corresponding to the magnets 12 attached to the rotating table 7. ing.

この回転板１３にはさらにローラ（図示せず）が磁石１
４と略同一円周上でかつ近傍に設けられており磁石１２
．１４内の距離を近くするとともに一定に保っている。This rotary plate 13 further includes a roller (not shown) that is attached to the magnet 1.
Magnet 12 is provided on approximately the same circumference as 4 and near
．． 14 is kept close and constant.

しかして、この回転板１３の磁石１４と前記回転台７の
磁石１２の間には吸引力か゛働くようになっており、し
たがって回転板１３が駆動モータ１４によってベルト駆
動されれば、これにともなって回転台７が駆動されるよ
うになっている。Therefore, an attractive force is exerted between the magnet 14 of the rotary plate 13 and the magnet 12 of the rotary table 7, so that when the rotary plate 13 is driven by the belt by the drive motor 14, the magnet 12 of the rotary table 7 is driven by the belt. The rotary table 7 is driven by the rotation table 7.

ところで、加熱室５の底壁板６はこれらの磁石１２．１
４の磁力線を遮蔗しないように非強磁性金属板のステン
レスＳＵＳ ３０４アルミ等で構成されている。By the way, the bottom wall plate 6 of the heating chamber 5 has these magnets 12.1
It is made of a non-ferromagnetic metal plate such as stainless steel SUS 304 aluminum so as not to block the magnetic lines of force.

なお１５は回転台７の位置決め用の絞り部、１６は食品
用受皿、１７は食品である。Note that 15 is a constriction portion for positioning the rotary table 7, 16 is a food tray, and 17 is a food.

しかしながら、ステンレスＳＵＳ ３０４アルミ等の金
属板は高価であるとともに、塗装を施した場合塗装被膜
との化学的結合力がなく、密着性の点で鉄板と比較して
弱く、長年高周波加熱調理器を使用した場合に塗装被膜
がはがれる危険性がある。However, metal plates such as stainless steel SUS 304 aluminum are expensive, and when painted, they have no chemical bonding strength with the paint film, and their adhesion is weaker than iron plates, so they have not been used in high-frequency cooking appliances for many years. There is a risk that the paint film will peel off when used.

したがって本考案では非強磁性金属板で形成する底壁板
６は略ローラ１１近傍迄にとどめ、ローラ１１と磁石１
２間で絞り部１５を構成する鉄板とを重ね合わせて溶接
している。Therefore, in the present invention, the bottom wall plate 6 made of a non-ferromagnetic metal plate is limited to approximately the vicinity of the roller 11, and the roller 11 and the magnet 1
The iron plate constituting the constricted portion 15 is overlapped and welded between the two.

なお１８は非強磁性金属板と鉄板との重ね合わせ部であ
るが、非強磁性金属板端部は加熱室外に重ね合わせ溶接
時の位置決めのため延長してもよいことは云うまでもな
い。Note that reference numeral 18 indicates the overlapping portion of the non-ferromagnetic metal plate and the iron plate, but it goes without saying that the end portion of the non-ferromagnetic metal plate may be extended outside the heating chamber for positioning during overlapping welding.

以上説明したように本考案によれば次のような効果が期
待できる。As explained above, according to the present invention, the following effects can be expected.

（１）塗装被膜のはがれる危険性のある非強磁性金属板
は回転台７の下部で人目のつかない部分にあり、塗装被
膜がはがれても不潔感を与えることがなく、かつ非強磁
性金属板は錆びないため実用上問題とならない。(1) The non-ferromagnetic metal plate, which is at risk of peeling off the paint film, is located in an out-of-the-way area at the bottom of the turntable 7, so that even if the paint film peels off, it will not give an unclean feeling, and the non-ferromagnetic metal plate The board does not rust, so there is no practical problem.

なお塗装被膜がはがれて問題となる場合は塗装時にマス
キングをおこない塗装をつけなくとも加熱室内の明るさ
清潔感をそこなう、ことはない。If the paint film peels off and becomes a problem, mask it during painting so that the brightness and cleanliness inside the heating chamber will not be affected even if no paint is applied.

（２）一般に非強磁性金属板は鉄板に比較して著しく価
格が高いが、本考案により非強磁性金属板の使用をきわ
めて少なく経済的である。(2) In general, non-ferromagnetic metal plates are significantly more expensive than iron plates, but the present invention makes it possible to reduce the use of non-ferromagnetic metal plates, making it economical.

（３）回転載置台７のローラ１１は外縁部に装置してい
るため、受皿１６の縁部に被加熱物を載置しても回転載
置台７は安定している。(3) Since the rollers 11 of the rotary mounting table 7 are installed on the outer edge, the rotary mounting table 7 is stable even if the object to be heated is placed on the edge of the saucer 16.

またこのローラ１１の接触する加熱室壁は塗装されてお
り塗装の凹凸が多少でるがこの場合においても絞り部に
近いため回転時に異常音を発生することがない。Further, the heating chamber wall that this roller 11 comes into contact with is painted, and the coating may have some unevenness, but even in this case, since it is close to the constriction part, no abnormal noise is generated during rotation.

ところが回転体１３の磁石１４の近傍に装着されるロー
ラ部に塗装がつき多少の凹凸が出ると底壁板６にタイコ
をたたくごとく異常音が発生するが本考案ではローラ近
傍に重ね合わせ部があり、ローラ近くの底壁板６を固定
した結果と同じとなり、たとえ塗装した場合でも異常音
の発生がなくなる。However, if the roller section attached near the magnet 14 of the rotary body 13 gets painted and becomes slightly uneven, an abnormal sound similar to hitting a hammer on the bottom wall board 6 will be generated. This is the same result as fixing the bottom wall plate 6 near the roller, and even if it is painted, no abnormal noise will occur.

したがって塗装時に加熱室裏面磁石１４の近傍をマスキ
ングをする必要がなく経済的である。Therefore, it is not necessary to mask the vicinity of the magnet 14 on the back surface of the heating chamber during painting, which is economical.
