Description

本発明は、磁性のある容器を加熱手段により電磁誘導加熱して調理を行う加熱調理器に関する。   The present invention relates to a cooking device that cooks a magnetic container by electromagnetic induction heating with a heating means.

一般に、電磁誘導式の加熱調理器(以下、電磁調理器)は、加熱手段に高周波電流を供給することによって、本体であるケース上部の天板(トッププレート)上に載置される鉄やステンレスなどの磁性のある容器に、電磁誘導による渦電流を発生させて加熱調理を行うものであり、上記高周波電流は、インバータ回路などから供給されるようになっている。   Generally, an electromagnetic induction heating cooker (hereinafter referred to as an electromagnetic cooker) supplies iron or stainless steel placed on a top plate (top plate) at the top of a case by supplying a high-frequency current to heating means. An eddy current due to electromagnetic induction is generated in a magnetic container such as the one for heating cooking, and the high-frequency current is supplied from an inverter circuit or the like.

一方、ケースの上部に備えられた天板は、ガラスや陶磁器などの非金属体で、非磁性体の材質で構成される。図6はその一例を示すものであるが、同図において、101は加熱調理器の本体で、これは底板102と天板受け103とケース104とにより外郭を構成すると共に、天板受け103に形成した開口部を覆うようにして、天板105が設けられる。天板105の上面すなわち表面105aは、本体101外部に露出しており略平坦に形成される。なおいずれも図示しないが、本体101の内部には、天板105の裏面に対向して加熱手段が設けられると共に、加熱手段に高周波電流を供給するインバータ回路などの駆動手段が設けられる。そして、天板105に前記磁性のある容器としての鍋106を載置して加熱調理を行なう。   On the other hand, the top plate provided in the upper part of the case is made of a non-magnetic material such as glass or ceramics. FIG. 6 shows an example. In FIG. 6, reference numeral 101 denotes a main body of the heating cooker, which forms an outer shell by the bottom plate 102, the top plate receiver 103 and the case 104, and A top plate 105 is provided so as to cover the formed opening. The top surface, that is, the surface 105a of the top plate 105 is exposed to the outside of the main body 101 and is formed to be substantially flat. Although not shown in the drawings, heating means is provided inside the main body 101 so as to face the back surface of the top plate 105, and driving means such as an inverter circuit for supplying a high-frequency current to the heating means is provided. Then, the pan 106 as the magnetic container is placed on the top plate 105 and cooking is performed.

しかし上記構成では、天板105の表面105aと鍋106の底面との摩擦力が小さいため、図6の破線で示すように、鍋106が滑って本体101の上部から落ちたり、天板105と鍋106の接触面を互いに傷付けたりする不具合があった。   However, in the above configuration, since the frictional force between the surface 105a of the top plate 105 and the bottom surface of the pan 106 is small, the pan 106 slides down from the top of the main body 101 as shown by the broken line in FIG. There was a problem that the contact surfaces of the pan 106 were damaged each other.

そこで、このような不具合を防止するため、図7に示すように、天板105の外周上面に凸部108を設けることで、鍋106が天板105の表面105aにおいて滑り落ちるのを防止するものが知られている。またこれに関連して、特許文献1には非磁性体面と天板の上面に段差を設けることで鍋の移動を防止することが示されている。さらに、図8に示すように、鍋106の底面外周部分にリブ109を設けて、鍋106に嵌合部110を形成し、前記嵌合部110をケース104の上部に直接取付けられた天板105に嵌合することで、鍋106の滑りを防止することが、例えば特許文献2などにおいて知られている。

Therefore, in order to prevent such a problem, as shown in FIG. 7, a protrusion 108 is provided on the outer peripheral upper surface of the top plate 105 to prevent the pan 106 from sliding down on the surface 105 a of the top plate 105. Are known. In connection with this, Patent Document 1 discloses that a pan is prevented from moving by providing a step on the non-magnetic surface and the top surface of the top plate. Further, as shown in FIG. 8, a rib 109 is provided on the outer peripheral portion of the bottom surface of the pan 106 to form a fitting portion 110 in the pan 106, and the top plate is directly attached to the upper portion of the case 104. It is known, for example, in Patent Document 2 to prevent the pan 106 from slipping by being fitted to 105.

しかし、図7に示すような構造の凸部108を有する天板105では、使用する鍋106のサイズが制約される。すなわち、図9に示すように、天板105より極端に小さい鍋106の場合、または図10に示すように、天板105より大きい鍋106の場合は、鍋106の滑りや傷付きを防止できない。さらに図10に示すような大きな鍋106では、鍋106の底面が凸部108の上端に乗り上げて、天板105との間に隙間111を生じ、鍋106が加熱手段から離れてしまって十分加熱されず、調理をすることができないという不具合があった。しかも、天板105において凸部108を設けるための成形が必要となり、製造コストの上昇を招くだけでなく、上方に突出した凸部108が加熱調理器のデザインをする上で制約になる不具合があった。   However, in the top plate 105 having the convex portion 108 having the structure as shown in FIG. 7, the size of the pan 106 to be used is restricted. That is, as shown in FIG. 9, when the pan 106 is extremely smaller than the top plate 105, or when the pan 106 is larger than the top plate 105 as shown in FIG. . Further, in the large pan 106 as shown in FIG. 10, the bottom surface of the pan 106 rides on the upper end of the convex portion 108, and a gap 111 is formed between the pan 105 and the pan 106 is separated from the heating means and heated sufficiently. There was a problem that it was not possible to cook. In addition, it is necessary to form the convex portion 108 on the top plate 105, which not only causes an increase in manufacturing cost, but also has a problem that the convex portion 108 that protrudes upward becomes a limitation in designing the cooking device. there were.

また、上記図8に示すようなリブ109を備えた鍋106では、嵌合部110に適合する加熱調理器でなければならず、これもデザイン上の制約を著しく受けると共に、別な形状の鍋106では対応できず、融通がきかないという不具合があった。   In addition, the pan 106 having the rib 109 as shown in FIG. 8 must be a heating cooker that fits the fitting portion 110, which is significantly limited in design and has a different shape. There was a problem that 106 could not handle it and it was not flexible.

本発明は上記問題点を解決して、容器の種類、形状および大きさを問わずに調理容器が滑って移動することを防止し、使い易さと安全性を向上するとともに、簡便な構成によってデザイン性の向上とコストダウンを図ることができる電磁誘導加熱調理器を提供することを目的とする。   The present invention solves the above problems, prevents the cooking container from sliding and moving regardless of the type, shape and size of the container, improves usability and safety, and is designed with a simple configuration. It aims at providing the electromagnetic induction heating cooking device which can aim at the improvement of property, and cost reduction.

本発明の加熱調理器は、上記目的を達成するために、加熱手段により容器を電磁誘導加熱する加熱調理器において、前記容器を載置する摩擦部材を設けている。   In order to achieve the above object, the heating cooker of the present invention is provided with a friction member for placing the container in the heating cooker in which the container is electromagnetically heated by a heating means.

摩擦部材に容器を載せると、摩擦部材の材質の特性により鍋の底面と摩擦部材の表面との間に摩擦力が発生し、この摩擦力は摩擦部材に対する水平方向への保持力として容器に働いて、容器の滑りや傷付きを防止することができる。さらに容器内に食材などを収容すれば、容器と摩擦部材の表面の摩擦力はより大きくなり、容器の水平方向の滑りや傷付きをより効果的に防止できる。さらに、こうした滑りや傷つき防止のために、容器の底面や摩擦部材の表面を複雑な形状にすることもなく、簡便な構成によってデザイン性の向上とコストダウンを図ることができる。   When the container is placed on the friction member, a frictional force is generated between the bottom surface of the pan and the surface of the friction member due to the characteristics of the material of the friction member, and this frictional force acts on the container as a holding force in the horizontal direction with respect to the friction member. Thus, slipping and scratching of the container can be prevented. Furthermore, if foodstuffs etc. are accommodated in a container, the frictional force of the surface of a container and a friction member will become larger, and the horizontal slip and damage | wound of a container can be prevented more effectively. Furthermore, in order to prevent such slipping and scratching, the design can be improved and the cost can be reduced with a simple configuration without making the bottom surface of the container and the surface of the friction member complicated.

本発明の加熱調理器は、加熱手段により容器を電磁誘導加熱する加熱調理器において、前記容器を載置する摩擦部材を設けたものであり、容器の種類、形状および大きさを問わずに調理容器が滑って移動することを防止し、使い易さと安全性を向上するとともに、簡便な構成によってデザイン性の向上とコストダウンを図ることができる。   The heating cooker of the present invention is a heating cooker in which a container is electromagnetically heated by a heating means, provided with a friction member for placing the container, and cooks regardless of the type, shape and size of the container. The container can be prevented from slipping and moving, improving ease of use and safety, and improving design and reducing costs with a simple configuration.

以下、添付図面を参照しながら本発明の一実施例について説明する。加熱調理器の概略構成を示す図1〜図3の各図において、1は誘導コイル26(図4参照)をその内部に備えた加熱調理器の本体で、この本体1は、床面などに載置される底板2と、底板2の上部に設けられた本体1の外殻側面をなす筒状のケース3と、このケース3の上部に装着される枠状の天板受け4とを備え、底板2と天板受け4とによりケース3が狭持されている。このケース3には、電源のオン・オフスイッチや加熱量の調節スイッチなどを含む操作部(図示せず)が設けられている。   Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. 1-3 which shows schematic structure of a heating cooker, 1 is the main body of the heating cooker which equipped the induction coil 26 (refer FIG. 4) in the inside, This main body 1 is on a floor surface etc. A bottom plate 2 to be placed, a cylindrical case 3 that forms the outer shell side surface of the main body 1 provided on the top of the bottom plate 2, and a frame-shaped top plate receiver 4 that is mounted on the top of the case 3. The case 3 is held between the bottom plate 2 and the top plate receiver 4. The case 3 is provided with an operation unit (not shown) including a power ON / OFF switch, a heating amount adjustment switch, and the like.

天板受け4の内周部には、天板5と摩擦部材としてのラバー6を載せるための段部7が設けられる。天板5は上述の通り、ガラスや陶磁器などの非金属体であって非磁性体の材質で構成され、その表面5aは滑らかに処理されている。また、天板5の上面に載せられるラバー6は、厚さ1〜2mm程度の例えばシリコーンゴム製で平板状に形成され、おおよそ天板5の表面全体を覆い隠すように設けられる。なお、シリコーンゴムに代わる摩擦部材として、この他にフッ素ゴムなどを用いても良い。前記天板受け4の段部7に天板5とラバー6を順に嵌合載置すると、天板受け4の開口部が塞がれ、本体1の上面が段部7の上面7aがラバー6の表面6aよりも若干低い位置かもしくは概ね面一となる。   A step 7 for placing the top plate 5 and the rubber 6 as a friction member is provided on the inner periphery of the top plate receiver 4. As described above, the top plate 5 is made of a non-metallic material such as glass or ceramics, and its surface 5a is treated smoothly. Further, the rubber 6 placed on the top surface of the top plate 5 is made of, for example, a silicone rubber having a thickness of about 1 to 2 mm and is formed in a flat plate shape so as to cover the entire surface of the top plate 5 approximately. In addition, fluorine rubber or the like may be used as a friction member instead of silicone rubber. When the top plate 5 and the rubber 6 are sequentially fitted and placed on the step 7 of the top plate receiver 4, the opening of the top plate receiver 4 is closed, and the upper surface of the main body 1 is the upper surface 7 a of the step 7. The surface 6a is slightly lower than or substantially flush with the surface 6a.

調理用の容器である有底状の鍋8は、平坦なラバー6の上面に載置される。この鍋8は平坦な底面を有し、ラバー6の表面6aと底面全体で接している。鍋8は底面が略平坦で磁性のある容器であれば、様々なサイズのものを利用できる。この場合、鍋8は母材全体が磁性材料で形成されていても、あるいは熱伝導性の良い母材の外面に磁性材料が接合されていてもよい。鍋8の底面が平坦である理由は、ラバー6との摩擦力を極力大きくするためと、天板5の直下にある誘導コイル26に鍋8の底部をできるだけ近づけて、鍋8を効率よく加熱するためである。   A bottomed pan 8 that is a container for cooking is placed on the upper surface of a flat rubber 6. The pan 8 has a flat bottom surface and is in contact with the surface 6a of the rubber 6 over the entire bottom surface. The pot 8 can be of various sizes as long as the bottom is substantially flat and magnetic. In this case, the whole base material of the pan 8 may be formed of a magnetic material, or the magnetic material may be bonded to the outer surface of the base material having good thermal conductivity. The reason why the bottom surface of the pan 8 is flat is to heat the pan 8 efficiently by making the bottom of the pan 8 as close as possible to the induction coil 26 directly below the top plate 5 in order to increase the frictional force with the rubber 6 as much as possible. It is to do.

次に、電気的な構成を図4において説明すると、20は本体1内部の制御基板(図示せず)に設けられた制御手段としてのマイクロコンピュータ(以下、単にマイコンと称する)であり、これはいずれも図示しないが、周知のマイクロプロセッサを構成する制御装置や演算装置の他に、ROMやRAMなどからなる記憶装置および入出力装置などを備えて構成される。マイコン20の入力側には、ケース3に設けられる操作部の各種スイッチからなる操作手段21が設けられると共に、前記鍋8の温度を計測する温度検出手段としての温度センサ22が接続される。一方、マイコン20の出力側には電流供給回路25が接続され、この電流供給回路25から加熱手段である誘導コイル26に所定の電流を供給するようになっている。   Next, the electrical configuration will be described with reference to FIG. 4. Reference numeral 20 denotes a microcomputer (hereinafter simply referred to as a microcomputer) as control means provided on a control board (not shown) inside the main body 1. Although neither of them is shown, it is configured to include a storage device such as a ROM or a RAM, an input / output device, and the like in addition to a control device and an arithmetic device that constitute a known microprocessor. On the input side of the microcomputer 20, operating means 21 including various switches of an operating unit provided in the case 3 is provided, and a temperature sensor 22 as temperature detecting means for measuring the temperature of the pan 8 is connected. On the other hand, a current supply circuit 25 is connected to the output side of the microcomputer 20, and a predetermined current is supplied from the current supply circuit 25 to the induction coil 26 as heating means.

マイコン20は自身の保有するプログラムの機能的な構成として、温度センサ22により計測した鍋8の温度に基づき、誘導コイル26による加熱動作を制御する加熱制御手段31を備えている。またここでの加熱制御手段31は、操作手段で設定した設定温度に鍋8の検出温度が近づくように鍋8への加熱量を調節するが、ラバー6の耐熱温度よりも鍋8の検出温度が高くなると(例えば、シリコーン製のラバー6の耐熱温度が180〜200℃であったとすると、鍋8の温度がそれ以上になった場合)、強制的に誘導コイル26への電力供給を制限または遮断して、鍋8をラバー6から取り外すように表示や報知で促す加熱保護手段32を備えている。これにより、例えば鍋8で焼き物などの調理が行なわれた場合でも、ラバー6の熱変形などを確実に防止できる。   The microcomputer 20 is provided with a heating control means 31 for controlling the heating operation by the induction coil 26 based on the temperature of the pan 8 measured by the temperature sensor 22 as a functional configuration of the program held by the microcomputer 20. The heating control means 31 here adjusts the amount of heating to the pan 8 so that the detected temperature of the pan 8 approaches the set temperature set by the operating means, but the detected temperature of the pan 8 is higher than the heat-resistant temperature of the rubber 6. (For example, if the heat-resistant temperature of the rubber 6 made of silicone is 180 to 200 ° C., when the temperature of the pan 8 becomes higher), the power supply to the induction coil 26 is forcibly restricted or A heat protection means 32 is provided for prompting by display or notification to shut off and remove the pan 8 from the rubber 6. Thereby, for example, even when cooking such as pottery is performed in the pan 8, thermal deformation of the rubber 6 can be reliably prevented.

次に上記構成の作用について説明する。天板5上のラバー6に鍋8を載置した状態で、前記操作部のスイッチ(図示しない)を操作して電源をオンにすると、天板5の直下にある誘導コイル26に電流供給回路25から高周波電流が供給され、誘導コイル26から発生する交番磁界により、磁性のある鍋8が発熱して、鍋8内に投入された被調理物が加熱される。このときの鍋8への加熱量は、操作部の調節スイッチを操作することによって、適宜調節することができる。   Next, the operation of the above configuration will be described. When the power source is turned on by operating a switch (not shown) of the operation unit in a state where the pan 8 is placed on the rubber 6 on the top plate 5, a current supply circuit is connected to the induction coil 26 directly below the top plate 5. A high frequency current is supplied from 25, and the magnetic pot 8 generates heat by the alternating magnetic field generated from the induction coil 26, and the food to be cooked in the pot 8 is heated. The amount of heating to the pan 8 at this time can be appropriately adjusted by operating the adjustment switch of the operation unit.

マイコン20の加熱制御手段31は、温度センサ22により計測される鍋8の検出温度を読み取って、前記調節スイッチによる設定温度との比較結果に基づき、電流供給回路25を介して誘導コイル26の加熱出力を制御する。但し、ここでの鍋8の加熱温度は、ラバー6の耐熱温度よりも低くするのが好ましい。その理由は、ラバー6の耐熱温度以上に鍋8を加熱すると、ラバー6の材質が劣化したり変形して、摩擦力の低下を来たし、さらにはラバー6が熱変形する虞れもあるからである。例えば、ラバー6の材料としてシリコーンゴムを用いた場合は、シリコーンゴムの耐熱温度が通常約180〜200℃であるため、煮物などの調理では、鍋8内の水分によって沸点である100℃前後以上に鍋8の温度が上昇することはないが、汁気のない焼き物などの調理では、鍋8内に水分がないため100℃を超えて温度上昇することがある。その点本実施例では、温度センサ24による鍋8の検出温度が、水の沸点よりも高くラバー6の耐熱温度よりも低い例えば120℃に達したら、過熱保護手段32により電流供給回路25から誘導コイル26に供給される電流を制限または遮断する。こうして、加熱制御手段31により鍋8の温度をラバー6の耐熱温度以下に加熱制御することで、ラバー6の熱変形などを確実に防止することができる。   The heating control means 31 of the microcomputer 20 reads the detected temperature of the pan 8 measured by the temperature sensor 22 and heats the induction coil 26 via the current supply circuit 25 based on the comparison result with the set temperature by the adjustment switch. Control the output. However, the heating temperature of the pan 8 here is preferably lower than the heat resistance temperature of the rubber 6. The reason is that if the pan 8 is heated above the heat-resistant temperature of the rubber 6, the material of the rubber 6 deteriorates or deforms, resulting in a decrease in frictional force, and further, the rubber 6 may be thermally deformed. is there. For example, when silicone rubber is used as the material of the rubber 6, the heat resistance temperature of the silicone rubber is usually about 180 to 200 ° C. Therefore, in cooking such as boiled food, the boiling point is about 100 ° C. or higher due to moisture in the pan 8 Although the temperature of the pan 8 does not rise, the cooking temperature of the pot 8 may rise over 100 ° C. because there is no moisture in the pan 8. In this respect, in this embodiment, when the temperature detected by the temperature sensor 24 reaches the pot 8 which is higher than the boiling point of water and lower than the heat-resistant temperature of the rubber 6, for example, 120 ° C. The current supplied to the coil 26 is limited or cut off. Thus, by controlling the temperature of the pan 8 to be equal to or lower than the heat resistant temperature of the rubber 6 by the heating control means 31, it is possible to reliably prevent the rubber 6 from being thermally deformed.

一方、ラバー6の表面6aに鍋8を載せた時の摩擦係数は、ガラスや陶磁器などの天板5に鍋8を載せたときの摩擦係数よりもはるかに大きく、鍋8はラバー6上において滑りにくくなって、鍋8を水平方向に動かすには従来よりも大きな力が必要になる。さらに、鍋8内に被調理物である食材などを投入すると、鍋8自体の自重のみならず食材の侍従も加わって、鍋8の底面とラバー6の表面6aの摩擦力はより大きくなり、水平方向に鍋8が滑って移動することをより効果的に防止できる。また、鍋8が滑りにくくなる分だけ、鍋8の底面の擦れによる傷付きも防止できる。さらに、天板5はラバー6により覆われているので、これも傷付きが防止されると共に、ラバー6だけを着脱できる構造にしておけば、ラバー6単体での丸洗いも可能になって清掃性が向上する。   On the other hand, the friction coefficient when the pan 8 is placed on the surface 6a of the rubber 6 is much larger than the friction coefficient when the pan 8 is placed on the top plate 5 such as glass or ceramics. It becomes difficult to slip, and a greater force than before is required to move the pan 8 in the horizontal direction. Furthermore, when the foodstuff etc. which are to-be-cooked things are thrown in in the pan 8, not only the weight of the pan 8 itself but the obedience of foodstuffs will be added, and the frictional force of the bottom face of the pan 8 and the surface 6a of the rubber 6 will become larger, It is possible to more effectively prevent the pan 8 from sliding and moving in the horizontal direction. Moreover, the damage | wound by the rubbing of the bottom face of the pan 8 can also be prevented by the part which the pan 8 becomes difficult to slip. Furthermore, since the top plate 5 is covered with the rubber 6, it is also prevented from being scratched, and if only the rubber 6 is detachable, the rubber 6 can be washed with a single piece of rubber and can be cleaned. Will improve.

また、本体1の上面に関しても、ラバー6による滑り止め効果により、従来例の図7,図9および図10に示すようながたつき防止用の凸部108を設ける必要がなく、すっきりとしたシンプルなデザイン形状とすることができると共に、本体1の上面全体を平坦にできるので、図2に示すような本体1の上面よりも相当小さな鍋9であっても、あるいは図3に示すような本体の1の上面をはみ出す大きさの鍋10であっても、鍋9,10の滑りや傷付きを防止して、様々なサイズの鍋9,10を調理加熱することができる。   Further, with respect to the upper surface of the main body 1, it is not necessary to provide a bump 108 for preventing rattling as shown in FIGS. Since it can be made into a simple design shape and the whole upper surface of the main body 1 can be made flat, even if it is a pot 9 considerably smaller than the upper surface of the main body 1 as shown in FIG. 2, or as shown in FIG. Even if the pan 10 has a size that protrudes from the top surface of the main body 1, the pans 9 and 10 can be cooked and heated by preventing the pans 9 and 10 from slipping and scratching.

さらに、ラバー6そのものは平形状で、成形型がなくても抜き型で簡単に形成できる。そのため、本体1の上面に凸部108を設けないことと相俟って、より安価な滑り止め構造を実現できる。   Further, the rubber 6 itself has a flat shape and can be easily formed with a punching die without a molding die. Therefore, coupled with the fact that the convex portion 108 is not provided on the upper surface of the main body 1, a cheaper anti-slip structure can be realized.

以上のように本実施例では、加熱手段である誘導コイル26により容器である鍋8を電磁誘導加熱する加熱調理器において、鍋8(または鍋9,10)を載置する摩擦部材としてのラバー6を設けている。   As described above, in this embodiment, a rubber serving as a friction member on which the pan 8 (or pans 9 and 10) is placed in the heating cooker that electromagnetically heats the pan 8 that is a container by the induction coil 26 that is a heating means. 6 is provided.

この場合、天板5上のラバー6に鍋8を載せると、ラバー6の材質の特性により鍋8の底面とラバー6の表面6aとの間に摩擦力が発生し、この摩擦力は摩擦部材に対する水平方向への保持力として鍋8に働いて、鍋8の滑りや傷付きを防止することができる。さらに鍋8内に食材などを収容すれば、鍋8とラバー6の表面6aの摩擦力はより大きくなり、鍋8の水平方向の滑りや傷付きをより効果的に防止できる。さらに、こうした滑りや傷つき防止のために、鍋8の底面やラバー6の表面6aを複雑な形状にすることもなく、簡便な構成によってデザイン性の向上とコストダウンを図ることができる。   In this case, when the pan 8 is placed on the rubber 6 on the top plate 5, a frictional force is generated between the bottom surface of the pan 8 and the surface 6a of the rubber 6 due to the characteristics of the material of the rubber 6, and this frictional force is a friction member. It acts on the pan 8 as a holding force in the horizontal direction against the pan, and can prevent the pan 8 from slipping and scratching. Furthermore, if foodstuffs etc. are accommodated in the pan 8, the frictional force of the pan 8 and the surface 6a of the rubber 6 will become larger, and the horizontal slip and damage | wound of the pan 8 can be prevented more effectively. Furthermore, in order to prevent such slip and damage, the design can be improved and the cost can be reduced with a simple configuration without making the bottom surface of the pan 8 or the surface 6a of the rubber 6 into a complicated shape.

また、別の変形例として図5に示すように、摩擦部材であるラバー6は様々な形状にすることができる。図5(a)ではラバー6を円板形状とし、図5(b)ではラバー6を十文字形状とし、図5(c)ではラバー6を一重の円環形状とし、図5(d)ではラバー6の二重の円環形状とし、図5(e)では複数の扇形状のラバー6を配置し、さらに図5(f)では放射状に凸条のラバー6を配置して、本実施例と同様の効果を得ることができる。このようにすれば、ラバー6を滑り止め防止用としてだけではなく、本体1の上面のデザイン性向上のために利用することができる。   As another modification, as shown in FIG. 5, the rubber 6 that is a friction member can have various shapes. In FIG. 5A, the rubber 6 has a disk shape, in FIG. 5B, the rubber 6 has a cross shape, in FIG. 5C, the rubber 6 has a single annular shape, and in FIG. In FIG. 5 (e), a plurality of fan-shaped rubbers 6 are arranged, and in FIG. 5 (f), radially protruding rubbers 6 are arranged, Similar effects can be obtained. In this way, the rubber 6 can be used not only for preventing slipping but also for improving the design of the upper surface of the main body 1.

本発明は上記実施例に限定されるものではなく、本発明の要旨の範囲で種々の変形実施が可能である。例えば、ラバー6の材質,厚さ,形状等は、本体1の設計に適合するように、適宜選択可能である。また、ラバー6は接着剤を介して天板5上に固着しても良い。なお、上記実施例では摩擦部材としてラバー6を用いたものに基づいて説明したが、これに限定されるものではない。例えば、人工皮革のように摩擦係数が大きく、かつ、耐熱性のある材料であれば、ラバー6以外の材料であっても同様に用いることができる。   The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist of the present invention. For example, the material, thickness, shape, and the like of the rubber 6 can be appropriately selected so as to match the design of the main body 1. Further, the rubber 6 may be fixed on the top plate 5 via an adhesive. In addition, although the said Example demonstrated based on what used the rubber 6 as a friction member, it is not limited to this. For example, a material other than rubber 6 can be used in the same manner as long as it is a material having a large friction coefficient and heat resistance, such as artificial leather.
