Description

本発明は、加熱調理器に関するものであり、特に感温インクを印刷した加熱調理器に関するものである。
なお、上記加熱調理器は電磁調理器や誘導加熱調理器を含むものとする。 The present invention relates to a cooking device, and more particularly to a cooking device printed with temperature-sensitive ink.
In addition, the said heating cooker shall include an electromagnetic cooker and an induction heating cooker.

加熱調理器を用いて調理を行うと、天板上の鍋などの被加熱物と接する部分は被加熱物の温度と同等の温度となる。調理後に被加熱物を移動すると、今まで被加熱物を置いていた部分が露出するので従来から色々な工夫が為されてきた。
例えば、従来の加熱調理器において、本体ケースの上部に設置され、鍋等の金属製被加熱容器の設置面をなすトッププレートを、耐熱性ならびに対衝撃性にすぐれた透明材の結晶化ガラスで形成するとともに、そのトッププレート（天板）の裏面に、所定温度（例えば８０℃以上）で色表出する可逆性サーモペイントを用いて注意喚起表示を記載し、その注意喚起表示が被加熱容器の底で削り取られることがないようにすることで、調理器の耐用期間中に注意喚起表示をいささかも劣化することなく行うことができるようにしたという技術が開示されている（例えば特許文献１参照）。
また、誘導加熱調理器用上板の被誘導加熱物を置く面に、回路装置などで発生する微量の残熱や気温によって変色することがない変色温度が４０℃以上で、変色温度が９０℃以下の感温変色模様層を少なくとも一層形成したという技術が開示されている（例えば特許文献２参照）。 When cooking is performed using a heating cooker, the portion in contact with the object to be heated, such as a pan on the top plate, becomes a temperature equivalent to the temperature of the object to be heated. When the object to be heated is moved after cooking, since the portion where the object to be heated has been placed is exposed, various devices have been conventionally made.
For example, in a conventional cooking device, the top plate that is installed on the upper part of the main body case and forms the installation surface of a metal heated container such as a pan is made of crystallized glass of transparent material with excellent heat resistance and impact resistance. At the same time, a warning display is described on the back surface of the top plate (top plate) using a reversible thermopaint that displays color at a predetermined temperature (for example, 80 ° C. or more), and the warning display is a container to be heated. A technique has been disclosed in which the warning display can be performed without any deterioration during the service life of the cooker by preventing it from being scraped off at the bottom of the cooker (for example, Patent Document 1). reference).
Further, on the surface on which the induction heating object of the upper plate for the induction heating cooker is placed, the discoloration temperature that is not discolored by a small amount of residual heat or temperature generated in a circuit device or the like is 40 ° C. or more, and the discoloration temperature is 90 ° C. or less The technique of forming at least one layer of the temperature-sensitive discoloration pattern layer is disclosed (see, for example, Patent Document 2).

しかしながら、上記特許文献１で示される従来の加熱調理器では、感温変色インクの印刷は、鍋こすれによる印刷剥がれを考慮し、天板ガラス裏面に印刷を行っているが、鍋底の熱が天板ガラスを伝導するのに時間がかかるため、反応が悪いという問題があった。
また、上記特許文献２で示される従来の誘導加熱調理器では、感温変色インクを印刷後、オーバーコート層と呼ぶ、さらに上から覆い被せるように剥がれ防止の透明インクを印刷する方法もあるが、印刷工程が増えるため、コストアップとなる要因となっていた。 However, in the conventional cooking device shown in Patent Document 1, the temperature-sensitive color-changing ink is printed on the back surface of the top glass in consideration of the printing peeling due to the scrubbing of the pan. Since it takes time to conduct the reaction, there was a problem that the reaction was bad.
Further, in the conventional induction heating cooker disclosed in Patent Document 2, there is a method of printing a temperature-sensitive color change ink, which is called an overcoat layer, and further printing a transparent ink for preventing peeling so as to cover from above. Because of the increase in the printing process, this was a factor that increased the cost.

本発明は上記の課題を解決するために為されたものであり、感温変色塗料を保護しつつ、天面の全面又は一部で注意喚起表示を行うことができる加熱調理器を得ることを目的としている。 The present invention has been made to solve the above-described problems, and it is intended to obtain a heating cooker that can perform a warning display on the entire top surface or a part of the top surface while protecting the temperature-sensitive color-changing paint. It is aimed.

本発明によれば、鍋などの被加熱物を加熱する加熱部と、加熱部の上方に位置し、被加熱物が載置されるとともに、被加熱物側の面の少なくとも一部に、所定温度以上で変色する可逆性の感温変色塗料と、被加熱物と天板との間に水膜ができることで生じる滑りを防止する滑り防止塗料と、が印刷されている天板と、を備えたので、感温変色塗料を保護しつつ、天面の全面又は一部で注意喚起表示を行うことができる。 According to the present invention, a heating unit that heats an object to be heated, such as a pan, and the heating object that is positioned above the heating unit are placed on at least a part of the surface on the object to be heated side. A top plate on which a reversible temperature-sensitive color-changing paint that changes color at a temperature or higher and an anti-slip paint that prevents slippage caused by the formation of a water film between the object to be heated and the top plate are printed. Therefore, a warning display can be performed on the entire top surface or a part of the top surface while protecting the temperature-sensitive color changing paint.

FIG. 1 is a diagram showing a configuration of a heating cooker according to an embodiment of the present invention.
As shown in FIG. 1, the heating cooker 10 includes a main body 1 of the heating cooker and a transparent heat-resistant glass top plate 3 on which an upper surface of the main body 1 is formed and a heated object 2 such as a pan is placed. Composed. Further, the top plate 3 is provided with a thermal power setting unit 4 for setting the strength of the thermal power in the heating unit, a thermal power display unit, and the like. The main body 1 also has a grill 5 suitable for grilling fish and meat, and a plurality of rotary buttons and display units so that conditions such as heating power, cooking time, temperature, etc. can be set and displayed for the heating unit and the grill 5 etc. The front operation unit 6 is provided, and a heating coil (not shown) provided below the top plate 3 and constituting the substance of the heating unit.
In addition, although it is also possible to arrange | position the coil with the substantially same diameter as the heating coil conventionally used as a heating part, by using many heating coils smaller than this coil by disperse | distributing and using it, such as a pot It is also possible to arrange the object to be heated at a free position on the top 3. The configuration and operation for realizing such a system are as described in Japanese Patent Application No. 2007-267673, and heating coils 8a to 8t are dispersedly arranged below the top board 3 as shown in FIG. ing. In FIG. 8, 21 is a circuit for supplying a high-frequency current to each heating coil, 6e is a power switch, 22 is a display means, 10 is a heating coil 8a to 8t, a housing for housing the circuit 21 and the display means 22, and 6a to 6d. Represents a front operation unit on which the user adjusts the power. The heating coils 8a to 8t (hereinafter sometimes referred to as the heating coil 8) have a coil diameter of 100 mm or less, the distance between the edges of the coil is 20 mm or less, and the total area of the heating coil is the top plate lower surface area. A plurality of them are arranged in the depth direction and the lateral direction so as to be 50%. Although not shown, a heating coil having a coil diameter smaller than that of the heating coil 8 is arranged so as to fill a space between the heating coils 8.

また、図２は本願発明に係る天板の印刷パターンを示した概念図である。図２（ａ）は印刷パターンＡを上方から見た図であり、図２（ｂ）は印刷パターンＢを上方から見た図であり、図２（ｃ）は図２（ａ）のＡ―Ａ断面図または図２（ｂ）のＢ―Ｂ断面図である。
図２（ａ）〜（ｂ）に白い丸印で示されるドットパターンは滑り防止印刷模様の印刷パターンであり、図２（ｂ）において、黒で塗りつぶした丸印で示されるドットパターンは感温変色塗料（以下、感温変色印刷模様という）の印刷パターンである。また、図２（ｃ）に示すように、変色インクの厚さより大きい厚さで滑り防止塗料（以下、滑り防止印刷模様という）のパターン印刷が施される。この場合、滑り防止印刷模様の素材としてガラス系無機質や熱硬化型樹脂や紫外線硬化型樹脂などを用いて構成された印刷パターンを作り、さらに焼き付け工程により仕上げている。なお、滑り防止印刷模様の素材としては上記のものに限らず、比較的高い剛性と低い脆性をもち、有害物質を含まない素材であれば広範な材料を用いることができる。 FIG. 2 is a conceptual view showing a printing pattern on the top plate according to the present invention. 2A is a view of the print pattern A as viewed from above, FIG. 2B is a view of the print pattern B as viewed from above, and FIG. 2C is a view of FIG. It is A sectional drawing or BB sectional drawing of FIG.2 (b).
The dot pattern indicated by white circles in FIGS. 2A and 2B is a print pattern of an anti-slip print pattern, and the dot pattern indicated by black circles in FIG. 2B is temperature sensitive. It is a printing pattern of a discoloration paint (hereinafter referred to as a temperature-sensitive discoloration printing pattern). Further, as shown in FIG. 2C, pattern printing of an anti-slip paint (hereinafter referred to as anti-slip printing pattern) is performed with a thickness larger than the thickness of the discoloration ink. In this case, a printing pattern constituted by using a glass-based inorganic material, a thermosetting resin, an ultraviolet curable resin, or the like as the material of the anti-slip printing pattern is made and further finished by a baking process. The material for the anti-slip print pattern is not limited to the above, and a wide range of materials can be used as long as the material has relatively high rigidity and low brittleness and does not contain harmful substances.

図２に示すように、加熱調理器の天板３の鍋などの被加熱物２を設置する面に、変色温度が概ね４０℃以上の可逆性の感温変色印刷模様１１と、被加熱物と天板の間に水膜ができることで生じる水滑りを防止することを目的とする滑り防止印刷模様１２が、互いに重なることなく、交互に印刷されている。
なお上記の図では、格子状のドットパターンであるが、図３（ａ）のように感温変色印刷模様と、滑り防止印刷模様を所定の方向（図では縦方向）に連続して延びるように構成し、縞模様を構成するようにこれらの模様を交互に印刷するようにしても良い。また、図３（ｂ）のようにグリッドパターンを構成するように交互に印刷しても良いし、図３（ｃ）のようにハニカムパターンを構成するように交互に印刷しても良い。さらに、図示しないが、簡単な文字を構成するように交互に印刷しても良い。
また、印刷工程において、感温変色印刷模様と滑り防止印刷模様が、互いに重なり合わないよう、印刷工程における版ずれを見越して、わずかに隙間を設けることで、多少の版ずれを許容できるように工夫する必要がある。 As shown in FIG. 2, a reversible temperature-sensitive discoloration printing pattern 11 having a discoloration temperature of approximately 40 ° C. or higher, and an object to be heated, on the surface on which the object to be heated 2 such as a pan of the top plate 3 of the cooking device is installed. The anti-slip printed pattern 12 intended to prevent water slip caused by the formation of a water film between the top plate and the top plate is printed alternately without overlapping each other.
In the above figure, the dot pattern has a lattice shape, but as shown in FIG. 3A, the temperature-sensitive discoloration print pattern and the anti-slip print pattern extend continuously in a predetermined direction (vertical direction in the figure). These patterns may be printed alternately so as to form a striped pattern. Moreover, it may be printed alternately so as to form a grid pattern as shown in FIG. 3B, or may be printed alternately so as to form a honeycomb pattern as shown in FIG. Further, although not shown, printing may be performed alternately so as to form simple characters.
In addition, in the printing process, a slight misalignment can be allowed by providing a slight gap in anticipation of misregistration in the printing process so that the temperature-sensitive discoloration printing pattern and the anti-slip printing pattern do not overlap each other. It is necessary to devise.

また、図４は本発明の実施の形態における天板３上の印刷パターンと被加熱物との接触部を示す模式図である。図４（ａ）は天板３に被加熱物２を載置した場合の天板と被加熱物との接触との接触断面を示す模式図であり、図４（ｂ）は天板３と被加熱物２との接触面の拡大図である。滑り防止用止め印刷パターンのピッチは広過ぎると従来と同じ問題が発生し、逆にピッチが狭過ぎると被加熱部２が滑り易くなる。ピッチは図４（ｂ）に示すように被加熱物２の大きさに比べて十分に小さい２．５ｍｍ〜５ｍｍが好適である。また、感温変色印刷模様の厚さは滑り防止印刷模様の印刷パターンのみと接触するように、滑り防止印刷模様の厚さより小さくする。図４（ｂ）に示すように感温変色印刷模様の厚さは約０．１ｍｍ、滑り防止印刷模様の厚さは約０．２ｍｍが好適である。 FIG. 4 is a schematic diagram showing a contact portion between a printed pattern on the top 3 and an object to be heated in the embodiment of the present invention. FIG. 4A is a schematic diagram showing a contact cross section of the contact between the top plate and the heated object when the heated object 2 is placed on the top plate 3, and FIG. It is an enlarged view of a contact surface with the to-be-heated material 2. FIG. If the pitch of the anti-slip stop printing pattern is too wide, the same problem as in the conventional case occurs. Conversely, if the pitch is too narrow, the heated portion 2 becomes slippery. As shown in FIG. 4B, the pitch is preferably 2.5 mm to 5 mm, which is sufficiently smaller than the size of the article 2 to be heated. Further, the thickness of the temperature-sensitive discoloration printing pattern is made smaller than the thickness of the anti-slip printing pattern so as to come into contact with only the printing pattern of the anti-slip printing pattern. As shown in FIG. 4B, the thickness of the temperature-sensitive discoloration printing pattern is preferably about 0.1 mm, and the thickness of the anti-slip printing pattern is preferably about 0.2 mm.

図２（ｃ）に示すように、感温変色印刷模様の厚さが滑り防止印刷模様の厚さよりも小さくなるように印刷することにより、鍋などの被加熱物２が印刷面上をずれることなどにより擦れが生じても被加熱物２は図４（ａ）〜（ｂ）に示すように滑り防止印刷模様と接触するだけで、感温変色印刷模様の印刷面は直接被加熱物に接触することがないため、感温変色印刷模様の印刷剥がれを防止することができる。
なお、滑り防止印刷模様の厚さが感温変色印刷模様より大きいのが理想であるが、たとえ同等の高さであっても滑り防止印刷模様の硬度が高いので、感温変色印刷模様の剥がれを保護する効果が期待できる。 As shown in FIG. 2C, the object to be heated 2 such as a pan is displaced on the printing surface by printing so that the thickness of the temperature-sensitive discoloration printing pattern is smaller than the thickness of the anti-slip printing pattern. As shown in FIGS. 4A to 4B, the object to be heated 2 just comes into contact with the anti-slip printed pattern, and the printed surface of the temperature-sensitive discolored printed pattern directly contacts the object to be heated. Therefore, it is possible to prevent the temperature-sensitive discolored printing pattern from being peeled off.
Ideally, the thickness of the anti-slip print pattern should be larger than the temperature-sensitive discoloration print pattern, but the anti-slip print pattern has high hardness even at the same height, so the temperature-sensitive discoloration print pattern will peel off. We can expect effect to protect.

このように、滑り防止印刷模様１２の突起の間に４０℃以上で変色する可逆性の感温変色インクで印刷された感温変色印刷模様１１を天板３の全面に施すことにより、天板全面のどこに被加熱物２を置いても調理によって高温になった被加熱物２を検知して、天板上面の色が変わるので、ユーザーの注意を喚起することができ、火傷を防止することができる。しかも、従来と異なり、比較的高価なＬＥＤを用いず、より低コストの印刷技術を用いるため、低コスト化を図ることができる。
感温変色印刷模様１１を天板３の全面に施すことにより、さらにこの効果が高まる。
天板３の下方に設けられている従来の３口タイプの加熱コイルに代えて、天板３の全面に渡りその下方にほぼ均一に分散配置され、従来の加熱コイルの径よりも小さい径を有する複数の誘導加熱コイル８で加熱部７を構成した場合、鍋などの被加熱物２の位置が固定されない、天板のどこに被加熱物を設置しても加熱が行える加熱調理器では、感温変色印刷模様１１を天板３の全面に施すことにより、コストを著しく下げることができる。
従来のＬＥＤ等の表示灯による電気的な表示方式では格段に高いコストを招き、また、大きさの関係で加熱コイルの配置が制限され、注意喚起に十分な数のＬＥＤが配置されない場合もあるが、上記の感温変色印刷模様１１を用いることで以上の問題を解決することができる。
また、感温変色印刷模様１１を滑り防止印刷模様１２の突起の隙間に印刷することで鍋との擦れによる印刷の剥がれの問題も殆どなく、長期にわたり表示性能を維持することができる。 In this way, by applying the temperature-sensitive color-change printing pattern 11 printed with the reversible temperature-sensitive color-changing ink that changes color at 40 ° C. or higher between the protrusions of the anti-slip printed pattern 12 on the entire surface of the top plate 3, Regardless of where the heated object 2 is placed on the entire surface, the heated object 2 that has become hot due to cooking is detected and the color of the top surface of the top changes, so that the user can be alerted and burns can be prevented. Can do. In addition, unlike the prior art, relatively inexpensive LEDs are not used, and a lower cost printing technique is used, so that the cost can be reduced.
This effect is further enhanced by applying the temperature-sensitive discoloration printing pattern 11 to the entire surface of the top 3.
Instead of the conventional three-port type heating coil provided below the top plate 3, it is distributed almost uniformly below the top plate 3 and has a diameter smaller than the diameter of the conventional heating coil. When the heating unit 7 is composed of a plurality of induction heating coils 8 having a heating cooker that does not fix the position of the object 2 to be heated, such as a pan, and that can heat the object to be heated anywhere on the top plate, By applying the temperature-change color printed pattern 11 to the entire surface of the top plate 3, the cost can be significantly reduced.
The conventional electric display method using indicator lights such as LEDs incurs a remarkably high cost, and the arrangement of heating coils is limited due to the size, and there are cases where a sufficient number of LEDs are not arranged for alerting. However, the above-described problems can be solved by using the above-described temperature-sensitive discoloration printing pattern 11.
Further, by printing the temperature-sensitive discoloration printed pattern 11 in the gaps between the protrusions of the anti-slip printed pattern 12, there is almost no problem of peeling of the print due to rubbing with the pan, and the display performance can be maintained for a long time.

また、天板３の上面のヒーターの有る加熱部７はＬＥＤ等による電気的な注意表示を行い、加熱部７以外のその他の部分に変色印刷模様を施すように構成してもよい。これにより、調理終了後の高温の被加熱物をヒーター部以外の部分に移動させても、変色インクの作用によって、高温部を注意喚起することが可能であり、加熱ヒーター部をより視覚的効果の高いＬＥＤによって高温注意喚起を行うことで、安全性を高めることができる。 Moreover, the heating part 7 with the heater on the upper surface of the top plate 3 may be configured to display an electrical caution by an LED or the like and to apply a discoloration printing pattern to other parts other than the heating part 7. As a result, even if the high-temperature object to be heated after cooking is moved to a part other than the heater part, it is possible to alert the high-temperature part by the action of the discoloration ink, and the heater part is more visually effective. Safety can be enhanced by calling attention to high temperature with a high LED.

なお、トップコートを持たない場合には、変色模様がそのままユーザーに見えるので、変色度合いも確認しやすく、低コスト化を実現できる。 If the topcoat is not provided, the discoloration pattern is visible to the user as it is, so the degree of discoloration can be easily confirmed, and cost reduction can be realized.
