It relates to what can be obtained.
従来から、電子レンジの扉部分等には、電子レンジ内部の空気が外部に漏れないように、シリコーンゴム等からなるパッキンが取付けられ、このパッキンにより気密が図られていた（例えば、特許文献１参照。）。 Conventionally, a packing made of silicone rubber or the like has been attached to a door portion of a microwave oven so that air inside the microwave oven does not leak to the outside, and this packing has been airtight (for example, Patent Document 1). reference.).
本件に関連する他の技術として、例えば、特許文献２、特許文献３が挙げられる。 Other techniques related to this case include, for example, Patent Document 2 and Patent Document 3.
ここで、近年における電子レンジには、マイクロ波による加熱のみではなく、スチーム機能を付加したものがある。このようなスチーム機能を付加した電子レンジの場合、電子レンジ内部で大量に発生する水蒸気が外部に漏れないようにするため、パッキンによる気密性を更に高める必要がある。 Here, some recent microwave ovens have not only heating by microwaves but also a steam function. In the case of a microwave oven to which such a steam function is added, it is necessary to further improve the airtightness by packing in order to prevent a large amount of water vapor generated inside the microwave oven from leaking to the outside.
パッキンにより気密を図る際には、押圧の力を強くすることで気密性を高めることが考えられるが、この場合、上記した従来技術に記載されたようなパッキンでは、パッキンを保持している樹脂基材に余計な力が掛かり、樹脂基材が歪んでそこから水蒸気が漏れてしまう恐れがある。また、余計な力が掛からないようにパッキンの硬度を低いものとした場合には、パッキンが樹脂機材から外れ易くなるという別の問題が生じてしまう。 When attempting to achieve airtightness by packing, it is conceivable to increase the airtightness by increasing the pressing force. In this case, in the packing as described in the prior art described above, the resin holding the packing An excessive force is applied to the base material, and the resin base material may be distorted and water vapor may leak therefrom. In addition, when the packing has a low hardness so that an extra force is not applied, another problem arises that the packing is easily detached from the resin material.
本発明はこのような点に基づいてなされたもので、その目的とするところは、軽微な押圧でも充分な気密性が得られるパッキンを提供することにある。 The present invention has been made based on such points, and an object of the present invention is to provide a packing that can obtain sufficient airtightness even with slight pressing.
上記目的を達成するべく本発明の請求項１によるパッキンは、弾性材料からなり、中空部分を有する筒部と、該筒部に形成され取付に寄与する係止部と、上記筒部の上記係止部と反対側に形成されたヒレ部とからなるパッキンにおいて、上記筒部と上記係止部とが断面略コの字形状をなすように形成されているとともに、略コの字形状開口部分において、上記筒部には上記係止部と上記筒部との間隔が広くなるように傾斜部が形成されていることを特徴とするものである。
又、本発明の請求項２によるパッキンは、上記筒部と上記係止部の境界部分近傍において、上記略コの字形状開口部と反対側に突出部が形成されていることを特徴とするものである。
又、本発明の請求項３によるパッキンは、上記弾性材料がシリコーンゴムからなることを特徴とするものである。
又、本発明の請求項４によるパッキンは、上記シリコーンゴムのＪＩＳ Ａ硬度計で測定した硬度が４０〜８０であることを特徴とするものである。
In order to achieve the above object, a packing according to claim 1 of the present invention is made of an elastic material, and has a cylindrical portion having a hollow portion, a locking portion formed in the cylindrical portion and contributing to attachment, and the engagement of the cylindrical portion. In the packing comprising a fin portion formed on the side opposite to the stopper portion, the cylindrical portion and the locking portion are formed so as to form a substantially U-shaped cross section, and a substantially U-shaped opening portion. In the above, the cylindrical portion is formed with an inclined portion so that a gap between the locking portion and the cylindrical portion is widened.
The packing according to claim 2 of the present invention is characterized in that a protruding portion is formed on the opposite side of the substantially U-shaped opening in the vicinity of the boundary portion between the cylindrical portion and the locking portion. Is.
The packing according to claim 3 of the present invention is characterized in that the elastic material is made of silicone rubber.
The packing according to claim 4 of the present invention is characterized in that the silicone rubber has a hardness measured by a JIS A hardness meter of 40 to 80.
本発明によれば、中空部分、ヒレ部、傾斜部の３つのクッション要素により、軽微な押圧であっても充分な気密性を得ることができる。勿論、パッキンを取付けた基材に余計な力が掛かり、基材が歪んでしまうようなことはない。 According to the present invention, sufficient airtightness can be obtained even with a slight pressure by the three cushion elements of the hollow portion, the fin portion, and the inclined portion. Of course, an extra force is not applied to the base material to which the packing is attached, and the base material is not distorted.
以下、図面を参照して、本発明による実施の形態の一例を説明する。 Hereinafter, an example of an embodiment according to the present invention will be described with reference to the drawings.
図１に示すように、横幅が５．４ｍｍ、高さが７．１ｍｍ、長さが１２００ｍｍのパッキン１がある。中空部２ａを有する筒部２には、断面略コの字形状となるように係止部３が形成され、また、係止部３の反対側には、ヒレ部４が形成されている。 As shown in FIG. 1, there is a packing 1 having a lateral width of 5.4 mm, a height of 7.1 mm, and a length of 1200 mm. The cylindrical portion 2 having the hollow portion 2 a is formed with a locking portion 3 so as to have a substantially U-shaped cross section, and a fin portion 4 is formed on the opposite side of the locking portion 3.
パッキン１を構成する材料としては、弾性材料であれば何でも良く、特に制限はない。例えば、フッ素ゴム、シリコーンゴム、エチレン−プロピレンゴム、アクリルゴム、ニトリルゴム、クロロプレンゴム、ブチルゴム、スチレン−ブタジエンゴム、ウレタンゴムなどのゴム材料が挙げられる。この中でもシリコーンゴムは、低温から高温までの耐久性に優れ、柔軟であり、耐候性にも優れるとともに、無臭且つ食品衛生上問題が生じることがないことから、種々の用途に展開できるため好ましい。特に、ＪＩＳ Ａ硬度計で測定した硬度が４０〜８０（ＪＩＳ Ｃ ２１２３に準拠）であれば、軽微な力でも確実な気密性が得られるとともに、パッキンが基材から容易に外れてしまうことを防止できるため好ましい。また、上記したパッキンを構成する材料には、充填剤、顔料、耐熱向上剤、難燃剤等の各種添加剤を必要に応じて適宜配合しても良い。このようなものとして、例えば、シリカ、珪藻土、酸化チタン、酸化アルミニウム、酸化亜鉛、酸化鉄、酸化セリウム、マイカ、クレイ、炭酸亜鉛、炭酸マンガン、水酸化セリウム、ガラスビーズ、ポリジメチルシロキサン、アルケニル基含有ポリシロキサン、ポリオルガノシルセスキオキサンなどが挙げられる。又、複数種類の材料を配合しても良い。又、上記したゴム材料等を発泡させて使用しても良い。 The material constituting the packing 1 is not particularly limited as long as it is an elastic material. Examples thereof include rubber materials such as fluorine rubber, silicone rubber, ethylene-propylene rubber, acrylic rubber, nitrile rubber, chloroprene rubber, butyl rubber, styrene-butadiene rubber, and urethane rubber. Among these, silicone rubber is preferable because it is excellent in durability from low temperature to high temperature, is flexible, has excellent weather resistance, is odorless and does not cause any problems in food hygiene, and can be used in various applications. In particular, if the hardness measured with a JIS A hardness tester is 40 to 80 (based on JIS C 2123), it is possible to obtain a reliable airtightness even with a slight force, and the packing is easily removed from the base material. Since it can prevent, it is preferable. Moreover, you may mix | blend suitably various additives, such as a filler, a pigment, a heat resistance improving agent, a flame retardant, with the material which comprises the above-mentioned packing as needed. As such, for example, silica, diatomaceous earth, titanium oxide, aluminum oxide, zinc oxide, iron oxide, cerium oxide, mica, clay, zinc carbonate, manganese carbonate, cerium hydroxide, glass beads, polydimethylsiloxane, alkenyl group Examples thereof include polysiloxane and polyorganosilsesquioxane. A plurality of kinds of materials may be blended. Further, the above rubber material or the like may be used after being foamed.
又、上記したようなゴム材料を成形品として使用する際には、架橋する必要があるため、架橋剤が配合されることになるが、この架橋剤としては、一般的に用いられているものであればなんでも良く、特に限定されない。例えば、シリコーンゴムの場合、２，５ジメチル−２，５−ビス（ｔ−ブチルパーオキシ）ヘキサン、ジ−ｔ−ブチルパーオキサイド、ジクミルパーオキサイドなどの有機過酸化物が挙げられる。これらは、使用するゴム材料を考慮して適宜に選択する。 In addition, when the rubber material as described above is used as a molded product, it is necessary to crosslink, and therefore a crosslinking agent is blended. This crosslinking agent is generally used. Anything is acceptable as long as it is not particularly limited. For example, in the case of silicone rubber, organic peroxides such as 2,5 dimethyl-2,5-bis (t-butylperoxy) hexane, di-t-butyl peroxide, and dicumyl peroxide are exemplified. These are appropriately selected in consideration of the rubber material to be used.
パッキン１の成形に際しては、従来公知の種々の成形法を用いれば良く、例えば、射出成形、プレス成形、押出成形など特に制限はないが、生産性に優れるという点から押出成形により成形することが好ましい。このようにして所定形状に成形した後、加熱することで架橋をし、パッキン１とする。 For molding the packing 1, various conventionally known molding methods may be used. For example, there is no particular limitation such as injection molding, press molding, and extrusion molding. However, the molding may be performed by extrusion molding because it is excellent in productivity. preferable. Thus, after shape | molding in a predetermined shape, it bridge | crosslinks by heating and it is set as the packing 1. FIG.
本発明においては、上記したように、ヒレ部４、筒部２に形成された中空部分２ａ、筒部２に形成された傾斜部２ｂ、を有している。そのため、「ヒレ部４が筒部２側に倒れることによるクッション」「中空部分２ａが潰れることによるクッション」「傾斜部２ｂにより筒部２全体が倒れることによるクッション」の３つのクッション要素を得ることができる。そのため、軽微な力であっても、充分な気密性を得ることが可能となる。 In this invention, it has the fin part 4, the hollow part 2a formed in the cylinder part 2, and the inclination part 2b formed in the cylinder part 2 as mentioned above. Therefore, three cushion elements are obtained: “cushion due to collapse of the fin portion 4 toward the cylindrical portion 2”, “cushion due to the collapse of the hollow portion 2a”, and “cushion due to the entire cylindrical portion 2 falling due to the inclined portion 2b”. Can do. Therefore, sufficient airtightness can be obtained even with a slight force.
尚、図１に示すように、筒部２と係止部３の境界部分近傍において、略コの字形状開口部と反対側に突出部５を形成しても良い。こうすることで、パッキン１の略コの字形状開口部と反対側に隙間が生じた場合でも、突出部５によりこの隙間を塞ぐことができる。 In addition, as shown in FIG. 1, you may form the protrusion part 5 on the opposite side to the substantially U-shaped opening part in the boundary part vicinity of the cylinder part 2 and the latching | locking part 3. As shown in FIG. By doing so, even when a gap is formed on the side opposite to the substantially U-shaped opening of the packing 1, the gap can be closed by the protruding portion 5.
又、図１に示すように、係止部３には、かえし部３ａを形成しても良い。こうすることにより、パッキン１を基板等に取付けた際に外れ難くすることができる。また、係止部３にも傾斜部３ｂを形成しても良い。こうすることで、基板等にパッキン１を取付け易くすることができる。 Further, as shown in FIG. 1, a barb portion 3 a may be formed in the locking portion 3. By doing so, it is possible to make it difficult to remove the packing 1 when it is attached to a substrate or the like. Moreover, you may form the inclination part 3b also in the latching | locking part 3. FIG. By doing so, the packing 1 can be easily attached to the substrate or the like.
本発明によるパッキン１の使用態様として、端面ともう一方の端面とを接着剤等で接合し、リング状にして使用することも考えられる。 As a usage mode of the packing 1 according to the present invention, it is also conceivable that the end face and the other end face are joined with an adhesive or the like and used in a ring shape.
図３は、図１に示すパッキン１を上記のようにリング状とし、電子レンジ１０に使用されるパッキンとして適用した例である。電子レンジ１０の扉１１の内側は、樹脂製の基板１２が扉１１に嵌め込まれる構造となっており、この基板１２にパッキン１が取付けられる。基板１２へのパッキン１の取付けは、図３（Ｂ）に示すように、筒部２と係止部３とによる断面略コの字形状部分に基板１２を嵌入することによりなされる。このようにパッキン１が取付けられた状態で扉１１を閉めると、パッキン１は押圧を受けることになるが、この押圧は基材１２が歪まないように、触れる程度の軽微な押圧となる。本発明によるパッキン１であれば、上記したように、中空部分２ａ、ヒレ部４、傾斜部２ｂの３つのクッション要素を有していることから、このような軽微な押圧であっても充分な気密性を得ることができる。そのため、電子レンジ１０のスチーム機能を実際に使用してみたが、水蒸気が漏れるようなことは全くなかった。 FIG. 3 shows an example in which the packing 1 shown in FIG. 1 has a ring shape as described above and is applied as a packing used in the microwave oven 10. The inside of the door 11 of the microwave oven 10 has a structure in which a resin substrate 12 is fitted into the door 11, and the packing 1 is attached to the substrate 12. As shown in FIG. 3B, the packing 1 is attached to the substrate 12 by inserting the substrate 12 into a substantially U-shaped section of the cylindrical portion 2 and the locking portion 3. When the door 11 is closed with the packing 1 attached in this manner, the packing 1 is pressed, but this pressing is a slight pressing so that the substrate 12 is not distorted. Since the packing 1 according to the present invention has the three cushion elements of the hollow portion 2a, the fin portion 4, and the inclined portion 2b as described above, even such a slight pressing is sufficient. Airtightness can be obtained. Therefore, when the steam function of the microwave oven 10 was actually used, water vapor did not leak at all.
尚、本発明は、上記した図１に示すようなパッキンに限定されるものではない。例えば、図２に示すように、ヒレ部４を垂直に形成しても良い。又、図１に示すパッキンではヒレ部４は、略コの字形状開口部側が先端となるように形成されているが、図１に示すパッキンとは逆に、略コの字状開口部側が根元となるようにヒレ部４を形成しても良い。 The present invention is not limited to the packing as shown in FIG. For example, as shown in FIG. 2, the fin portion 4 may be formed vertically. In addition, in the packing shown in FIG. 1, the fin portion 4 is formed so that the substantially U-shaped opening side is the tip, but on the contrary to the packing shown in FIG. 1, the substantially U-shaped opening side is You may form the fin part 4 so that it may become a root.
又、係止部３についても、図１に示す形状に限定されることはなく、傾斜部３ｂを形成しない形状でも良いし、かえし部３ａを形成しない形状でも良い。要は、筒部２と係止部３とが断面略コの字形状をなすように形成されていれば良く、詳細については取付ける基板の形状に応じて適宜に設計すれば良い。 Further, the locking portion 3 is not limited to the shape shown in FIG. 1 and may have a shape not forming the inclined portion 3b or a shape not forming the barb portion 3a. In short, it is only necessary that the cylindrical portion 2 and the locking portion 3 are formed to have a substantially U-shaped cross section, and the details may be appropriately designed according to the shape of the substrate to be attached.
又、突出部５は、必要に応じて適宜に形成すれば良く、突出部５の形状についても目的に応じて適宜設計すれば良い。 The protrusion 5 may be appropriately formed as necessary, and the shape of the protrusion 5 may be appropriately designed according to the purpose.
以上、詳述したように本発明によれば、軽微な押圧でも充分な気密性が得られるパッキンを提供することができる。従って本発明によるパッキンは、例えば、電子レンジ、温蔵庫、蒸し器、乾燥機、クーラーボックス、炊飯器、ジャーポット、食器洗浄器などなどをはじめとして、各種密封手段に好適に使用が可能である。 As described above in detail, according to the present invention, it is possible to provide a packing capable of obtaining sufficient airtightness even with slight pressing. Therefore, the packing according to the present invention can be suitably used for various sealing means including, for example, a microwave oven, a warm storage, a steamer, a dryer, a cooler box, a rice cooker, a jar pot, a dishwasher, and the like. .
