Description

本発明は、一般家庭、あるいは業務用に使用する炊飯器に関するものである。 The present invention relates to a rice cooker used for general home use or business use.

炊飯器は、従来より、台所を主に配置されていた。台所は、常に食物及び水がある為、ゴキブリが繁殖しやすい環境にある。炊飯器には、炊飯器の内部を冷却する目的で開口部が多数存在する為、その開口部からコキブリの侵入は可能であった。また、ゴキブリは、室温が２５℃〜３１℃の状態を好む為、特に室温の低い冬期においては、炊飯器が通電状態にあると、基板部品及び加熱手段等の自己発熱により炊飯器内部の雰囲気温度は上昇し、前述のゴキブリの好む室温２５℃〜３１℃とほぼ同等になっていた。更には、ゴキブリは、自身の身体がこすれる程度の隙間、身を隠せる暗い場所を好む習性があり、炊飯器の内部はゴキブリが存在するには、最適の環境下にあった。 Conventionally, rice cookers have been mainly arranged in the kitchen. The kitchen is in an environment where cockroaches are easy to breed because there is always food and water. Since there are many openings in the rice cooker for the purpose of cooling the inside of the rice cooker, intrusion of cockroaches was possible from the opening. In addition, since cockroaches prefer a state where the room temperature is 25 ° C. to 31 ° C., especially in the winter when the room temperature is low, when the rice cooker is in an energized state, the atmosphere inside the rice cooker due to self-heating of the substrate components and heating means, etc. The temperature rose and was almost equivalent to the room temperature of 25 ° C. to 31 ° C. preferred by the above cockroach. Furthermore, cockroaches have a habit of preferring a gap where the body is rubbed, and a dark place where the body can be hidden, and the inside of the rice cooker was in an optimal environment for the presence of cockroaches.

上記理由で、ゴキブリが繁殖している台所に設置された炊飯器の内部には、多くのゴキブリが炊飯器の内部に侵入し、一旦炊飯器の内部に侵入したコキブリは炊飯器の内部に滞在する傾向にあった。 For the above reasons, many cockroaches enter the inside of the rice cooker installed in the kitchen where cockroaches are breeding, and the cockroach once invaded inside the rice cooker stays inside the rice cooker Tended to be.

特許文献１に、従来例の炊飯器が開示されている。従来例の炊飯器は、操作基板及び加熱基板とそれぞれに対応した基板ベースとの間に発生する隙間を０．３ｍｍ〜０．５ｍｍとする構成としたものである。この構成をとることにより、炊飯器内部に侵入したゴキブリは操作基板及び加熱基板とそれぞれに対応した基板ベースの間に侵入できなくなるため、ゴキブリが各基板背面にあるパターン間をショートすることがないため、炊飯器の基板故障を抑制するものである。 Patent Document 1 discloses a conventional rice cooker. The conventional rice cooker has a configuration in which a gap generated between the operation substrate and the heating substrate and the corresponding substrate base is set to 0.3 mm to 0.5 mm. By adopting this configuration, cockroaches that have entered the inside of the rice cooker cannot enter between the operation substrate and the heating substrate and the corresponding substrate base, so that the cockroaches do not short-circuit between the patterns on the back of each substrate. Therefore, the substrate failure of the rice cooker is suppressed.

特許第４２５４６５９号公報Japanese Patent No. 4254659

特許文献１に開示された従来例の炊飯器の操作表示部の構成を図１１、図１２を用いて説明する。図１１は、従来例の炊飯器の前方中心部の要部断面図、図１２は、従来例の炊飯器の操作ボタン近傍の要部断面図である。 The structure of the operation display part of the rice cooker of the prior art example disclosed by patent document 1 is demonstrated using FIG. 11, FIG. FIG. 11 is a cross-sectional view of a main part of a front center portion of a conventional rice cooker, and FIG. 12 is a cross-sectional view of a main part near an operation button of the conventional rice cooker.

操作パネル１０１は、操作表示等を表面に印刷したフィルムと形状ベースとなる樹脂材で一体成形されており、上枠１０２の前方部に複数の爪嵌合で配設されている。その際、上枠１０２とは、操作パネル１０１の外周端部で、接触もしくは所定の隙間を有している。 The operation panel 101 is integrally formed of a film having operation display and the like printed on the surface and a resin material serving as a shape base, and is disposed at the front portion of the upper frame 102 with a plurality of claws. At this time, the upper frame 102 is an outer peripheral end portion of the operation panel 101 and has a contact or a predetermined gap.

また、操作パネル１０１は、その外表面にエンボス加工で形成されている複数個の操作ボタン１０３と、操作基板１０４に設置されている炊飯コースや炊飯時間等を表示するＬＣＤ１０５や炊飯コースを表示しているコース表示シート１０６を可視化するための透明可視部を有している。 In addition, the operation panel 101 displays a plurality of operation buttons 103 formed on the outer surface thereof by embossing, and an LCD 105 and a rice cooking course that display a rice cooking course, a rice cooking time, and the like installed on the operation board 104. A transparent visible portion for visualizing the course display sheet 106 is provided.

コース表示シート１０６は、ＬＣＤ１０５の上方に設置するため、設置時にＬＣＤ１０５の表示内容を可視化できるようにＬＣＤ１０５の表示部と対向する部位に穴の開いた形状を有している。 Since the course display sheet 106 is installed above the LCD 105, the course display sheet 106 has a shape with a hole in a portion facing the display unit of the LCD 105 so that the display content of the LCD 105 can be visualized at the time of installation.

それぞれの操作ボタン１０３の裏側には、相対する操作キー１０７を操作ボタン１０３と一定の隙間を有した状態で設置しており、その操作キー１０７の下方には、操作基板１０４の入力装置であるタクトスイッチ１０８を設置している。一定の隙間を有する構成にしているのは、初期状態での操作ボタン１０３の突き上げ防止のためである。操作キー１０７は、操作基板１０４上にＬＣＤ１０５を固定する役割を有する樹脂で成形されたＬＣＤホルダー１０９と共加工されている。 Opposite operation keys 107 are installed on the back side of each operation button 103 with a certain gap from the operation buttons 103. Below the operation keys 107 are input devices for the operation board 104. A tact switch 108 is installed. The reason for having a certain gap is to prevent the operation button 103 from being pushed up in the initial state. The operation key 107 is co-processed with an LCD holder 109 formed of a resin having a role of fixing the LCD 105 on the operation board 104.

ＬＣＤホルダー１０９は、前述のＬＣＤ１０５を設置するための凹部１１０と、その凹部１０９の外側に上面に設置するコース表示シート１０６を位置規制する役割を有するガイドリブ１１１を有している。前記ガイドリブ１１１は、使用者から見えないよう操作パネル１０１の透明可視部の外側に相当する位置に配設されている。また、前述の構成下では、コース表示シート１０６は本来の役割である炊飯コースを表示するだけでなく、ＬＣＤ１０５とＬＣＤホルダー１０９の凹部１１０に発生する隙間を隠す役割も有している。 The LCD holder 109 includes a recess 110 for installing the LCD 105 described above, and a guide rib 111 that serves to regulate the position of the course display sheet 106 installed on the upper surface outside the recess 109. The guide rib 111 is disposed at a position corresponding to the outside of the transparent visible portion of the operation panel 101 so as not to be seen by the user. Moreover, under the above-described configuration, the course display sheet 106 not only displays a rice cooking course, which is the original role, but also has a role of hiding a gap generated in the recess 110 of the LCD 105 and the LCD holder 109.

図１１に示すように操作パネル１０１とＬＣＤホルダー１０９のガイドリブ１１０には、ゴキブリが通過できる隙間（０．５ｍｍ以上）を有しているため、炊飯器本体内に侵入したゴキブリは操作基板１０４を介して、ガイドリブ１１１の内側に設置されているＬＣＤ１０５、コース表示シート１０６上を容易に通過でき、その状態を操作パネル１０１の透明可視部を介して炊飯器の使用者に目撃され、使用者に不快感を与えるという問題が発生した。 As shown in FIG. 11, the guide rib 110 of the operation panel 101 and the LCD holder 109 has a gap (0.5 mm or more) through which cockroaches can pass. Through the LCD 105 and the course display sheet 106 installed on the inner side of the guide rib 111, and the state is witnessed by the user of the rice cooker through the transparent visible portion of the operation panel 101. The problem of discomfort occurred.

上記、問題を解決するために操作パネル１０１とＬＣＤホルダー１０９のガイドリブ１１１を当接し、操作表示部へゴキブリが侵入する隙間を設けない構成とする方法も考えられるが、同構成では、操作パネル１０１の操作ボタン１０３を押す際に、操作キー１０７を押す力が前述の操作パネル１０１とＬＣＤホルダー１０９のガイドリブ１１１の当接部へと伝わり、操作キー１０７を押す力が分散してしまい、操作力の低下、操作力のバラツキ、また、ガイドリブ１１１の付属するＬＣＤホルダー１０９にはその他操作キー１０７が共加工されているため、近傍のその他操作キー１０７に力が伝わり使用者の意図に反して反応してしまう、等の問題を引き起こす可能性があり、さらには、落下等で操作パネル１０１の前面に力が付加された場合、操作パネル１０１とＬＣＤホルダー１０９のガイドリブ１１１の当接部からＬＣＤホルダー１０９を介して操作基板１０４に力が伝達し、場合によってはその力により操作基板１０４の破損を引き起こす可能性があるという課題があった。 In order to solve the above-described problem, a method may be considered in which the operation panel 101 and the guide rib 111 of the LCD holder 109 are brought into contact with each other so as not to provide a gap through which cockroaches enter the operation display unit. When the operation button 103 is pressed, the force for pressing the operation key 107 is transmitted to the contact portion between the operation panel 101 and the guide rib 111 of the LCD holder 109, and the force for pressing the operation key 107 is dispersed. The operation key 107 is co-processed on the LCD holder 109 to which the guide rib 111 is attached, so that the force is transmitted to the other operation key 107 in the vicinity and reacts against the user's intention. In addition, a force is applied to the front surface of the operation panel 101 due to a drop or the like. In this case, a force is transmitted from the contact portion between the operation panel 101 and the guide rib 111 of the LCD holder 109 to the operation substrate 104 via the LCD holder 109, and in some cases, the force may cause damage to the operation substrate 104. There was a problem.

The operation key 17 is generally co-processed with an LCD holder 19 formed of a resin having a role of fixing the LCD 14 on the operation board 7.

図４に示すように、ＬＣＤホルダー１９は、前述のＬＣＤ１４を設置するための凹部２０と、その凹部２０の外側に上面に設置するコース表示シート１５を位置規制する役割を有するガイドリブ２１を有している。なお、コース表示シート１５は、前述の構成により、炊飯コースを表示するだけでなく、ＬＣＤ１４とＬＣＤホルダー１９の凹部２０に発生する隙間を隠す役割も果たしている。 As shown in FIG. 4, the LCD holder 19 includes a recess 20 for installing the LCD 14 described above, and a guide rib 21 that serves to regulate the position of the course display sheet 15 installed on the upper surface outside the recess 20. ing. The course display sheet 15 not only displays the rice cooking course but also plays a role of hiding a gap generated in the recess 20 of the LCD 14 and the LCD holder 19 with the above-described configuration.

ガイドリブ２１は、使用者から見えないよう操作パネル１２の透明可視部１６の外側に相当する位置に配設され、操作パネルとの隙間（図４のＢ）を０．５ｍｍ以下になるように高さ設定している。その際、この操作パネル１２とガイドリブ２１の天面との隙間は、前述の操作パネル１２と上枠の嵌合隙間（図４のＡ）より大きく設定している。 The guide rib 21 is disposed at a position corresponding to the outside of the transparent visible portion 16 of the operation panel 12 so that the guide rib 21 cannot be seen by the user, and the gap (B in FIG. 4) with the operation panel is high so as to be 0.5 mm or less. Is set. At this time, the gap between the operation panel 12 and the top surface of the guide rib 21 is set larger than the fitting gap (A in FIG. 4) between the operation panel 12 and the upper frame.

以下に本発明の実施の形態１の炊飯器の操作時における操作部の動作を説明する。 Below, operation | movement of the operation part at the time of operation of the rice cooker of Embodiment 1 of this invention is demonstrated.

炊飯器の使用者が操作パネル１２の操作表示や操作パネル１２の透明可視部１６を介して、ＬＣＤ１４やコース表示シート１５の表示を確認し、使用したいコースを決定した後、そのコースに該当する操作ボタン１３を押すと、操作ボタン１３の裏側が操作キー１７の先端と接触し、操作キー１７の下方に設置している操作基板７の入力装置であるタクトスイッチ１８を押す。このタクトスイッチ１８が押されることにより操作基板７の入力装置からの信号を加熱基板９に伝達し、加熱基板９の加熱装置により、内鍋４を誘導加熱し
、鍋内の調理物１１を加熱調理する。 The user of the rice cooker confirms the display of the LCD 14 and the course display sheet 15 via the operation display of the operation panel 12 and the transparent visible portion 16 of the operation panel 12, determines the course to be used, and then corresponds to the course. When the operation button 13 is pressed, the back side of the operation button 13 comes into contact with the tip of the operation key 17, and the tact switch 18 that is an input device of the operation board 7 installed below the operation key 17 is pressed. When the tact switch 18 is pressed, a signal from the input device of the operation substrate 7 is transmitted to the heating substrate 9, the inner pan 4 is induction-heated by the heating device of the heating substrate 9, and the food 11 in the pan is heated. Cook.

本発明の実施の形態１の炊飯器においては、操作パネル１２とＬＣＤホルダー１９のガイドリブ２１の天面との隙間（図４のＢ）を０．５ｍｍ以下に設定しており、従来例の炊飯器に記載のように０．５ｍｍ以下の隙間をゴキブリは通過できないため、操作パネル１２とＬＣＤホルダー１９のガイドリブ２１の天面との隙間（図４のＢ）を介してゴキブリが炊飯器本体１の操作表示部内に侵入することはない。 In the rice cooker according to Embodiment 1 of the present invention, the gap (B in FIG. 4) between the operation panel 12 and the top surface of the guide rib 21 of the LCD holder 19 is set to 0.5 mm or less. Since the cockroach cannot pass through a gap of 0.5 mm or less as described in the cooker, the cockroach is attached to the rice cooker body 1 through the gap (B in FIG. 4) between the operation panel 12 and the top surface of the guide rib 21 of the LCD holder 19. No entry into the operation display section.

また、ＬＣＤホルダー１９のガイドリブ２１の天面との隙間（図４のＢ）を操作パネル１２と上枠の嵌合隙間（図４のＡ）より大きく設定することにより、使用者が操作ボタン１３を押した際に力が伝わる部位は、操作キー１７と操作パネル１２の外周端部と対向する上枠３のみである。このような構成をとることで、使用者が操作キー１７を押した際に、上枠３の外周端部より先にＬＣＤホルダー１９のガイドリブ２１が操作パネル１２に接触することはない。操作キー１７を押す力が、ＬＣＤホルダー１９のガイドリブ２１に伝わることがないため、操作力の設計の際には、操作キー１７と操作パネル１２の外周端部と対向する上枠３との接触のみを考慮すれば良いので、バラツキの少ない安定した操作力を設定することができる。また、ＬＣＤホルダー１９に共加工されているその他の操作キー１７に力が伝わることもないので、その他の操作キー１７が意図に反して反応するという問題も発生しない。さらには、落下等で操作パネル前面に力が付加された場合、ＬＣＤホルダー１９のガイドリブ２１を介して操作基板７に過度な力がかかることがなく、操作基板７の破損を引き起こすこともない。 Further, by setting the gap between the guide rib 21 of the LCD holder 19 and the top surface (B in FIG. 4) larger than the fitting gap between the operation panel 12 and the upper frame (A in FIG. 4), the user can operate the operation buttons 13. The only part where the force is transmitted when pressing is the upper frame 3 facing the operation key 17 and the outer peripheral end of the operation panel 12. With this configuration, when the user presses the operation key 17, the guide rib 21 of the LCD holder 19 does not come into contact with the operation panel 12 before the outer peripheral end portion of the upper frame 3. Since the pressing force of the operation key 17 is not transmitted to the guide rib 21 of the LCD holder 19, the contact between the operation key 17 and the upper frame 3 facing the outer peripheral end of the operation panel 12 is required when designing the operation force. Therefore, it is possible to set a stable operation force with little variation. In addition, since no force is transmitted to the other operation keys 17 that are co-processed on the LCD holder 19, the problem that the other operation keys 17 react unintentionally does not occur. Furthermore, when a force is applied to the front surface of the operation panel due to dropping or the like, an excessive force is not applied to the operation substrate 7 via the guide rib 21 of the LCD holder 19, and the operation substrate 7 is not damaged.

以上のように、本発明の実施の形態１の炊飯器においては、炊飯器本体の操作性能を低下させることなく、コギブリが炊飯器本体の操作表示部に侵入すること未然に防ぐことができ、使用者へ不快感を与えない炊飯器を提供することができる。 As described above, in the rice cooker of Embodiment 1 of the present invention, without lowering the operation performance of the rice cooker body, it is possible to prevent Kogori from entering the operation display unit of the rice cooker body, A rice cooker that does not cause discomfort to the user can be provided.

（実施の形態２）
図５を用いて、本発明の実施の形態２の炊飯器の説明をする。図５は、本発明の実施の形態２の炊飯器の前方中心部の要部断面図である。 (Embodiment 2)
The rice cooker of Embodiment 2 of this invention is demonstrated using FIG. FIG. 5: is principal part sectional drawing of the front center part of the rice cooker of Embodiment 2 of this invention.

図５において、操作パネル１２からＬＣＤホルダー１９のガイドリブ２１の外側にＬＣＤホルダー１９のガイドリブ２１の側面部を全周覆うゴキブリ侵入防止リブａ２２を配設し、ＬＣＤホルダー１９のガイドリブ２１の側面との隙間を（図５のＣ）０．５ｍｍ以下となるように構成している。 In FIG. 5, a cockroach intrusion prevention rib a22 that covers the entire side surface of the guide rib 21 of the LCD holder 19 from the operation panel 12 to the outside of the guide rib 21 of the LCD holder 19 is disposed. The gap is configured to be 0.5 mm or less (C in FIG. 5).

その他の構成及び動作、作用は実施の形態１と同様であるため、省略する。 Other configurations, operations, and actions are the same as those in the first embodiment, and thus are omitted.

本発明の実施の形態２の炊飯器は、上記構成をとることにより、従来例の炊飯器に記載のように０．５ｍｍ以下の隙間をゴキブリは通過できないため、ＬＣＤホルダー１９のガイドリブ２１とゴキブリ侵入防止リブａ２２の間にゴキブリが介在することはない。このことにより、ゴキブリが操作表示部内への侵入の可能性を低減することができる。なお、前述の効果は、隙間０．５ｍｍ以下の領域が大きいほど効果があるので、例えば、ゴキブリ侵入防止リブａ２２をＬＣＤホルダー１９の下面２３より凸となるまで伸ばしても良い。また、ゴキブリ侵入防止リブａ２２を操作パネル７と０．５ｍｍ以下の隙間になるように伸ばし、前述の隙間を上枠３と操作パネル１２の嵌合隙間（図４のＡ）大きくすると、炊飯器本体の操作性能を低下させることなく、操作基板７に介在するゴキブリが操作表示部内に侵入する可能性を低減することができる。 Since the rice cooker according to the second embodiment of the present invention has the above configuration, cockroaches cannot pass through a gap of 0.5 mm or less as described in the conventional rice cooker. There are no cockroaches between the intrusion prevention ribs a22. Thereby, the possibility that the cockroach enters the operation display unit can be reduced. In addition, since the above-described effect is more effective as a region having a gap of 0.5 mm or less is larger, for example, the cockroach intrusion prevention rib a22 may be extended from the lower surface 23 of the LCD holder 19 until it protrudes. In addition, when the cockroach intrusion prevention rib a22 is extended so as to have a gap of 0.5 mm or less from the operation panel 7, and the above-mentioned gap is increased to a fitting gap (A in FIG. 4) between the upper frame 3 and the operation panel 12, a rice cooker. The possibility that cockroaches intervening on the operation board 7 enter the operation display unit can be reduced without deteriorating the operation performance of the main body.
