以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（参考例１）
図１、図２は、本発明の参考例１における断熱機器である電気湯沸かし器を例示したものである。 (Reference Example 1)
1 and 2 illustrate an electric water heater which is a heat insulating device in Reference Example 1 of the present invention.

図に示すように、この電気湯沸かし器は、被収容物（水）２を収容する有底筒状の容器３と、容器３内の被収容物２を加熱・保温する加熱手段６と、サーミスターなどの感温素子７と、感温素子７からの電気信号により容器３内の被収容物２の温度を制御する制御回路１０と、容器３の上方開口部を開閉自在に覆う蓋体８と、蓋体８に内蔵された発泡ポリプロピレンなどの蓋断熱材９と、容器３の外周部に位置する筒状の断熱材１１と、断熱材１１の外周に位置するボデー１と、ボデー１上方に載置した上枠４とを備えている。   As shown in the figure, this electric water heater includes a bottomed cylindrical container 3 that accommodates an object (water) 2, a heating means 6 that heats and retains the object 2 in the container 3, and a thermistor. A control circuit 10 for controlling the temperature of the object 2 in the container 3 by an electric signal from the temperature sensing element 7, and a lid body 8 that covers the upper opening of the container 3 so as to be openable and closable. , A lid heat insulating material 9 such as foamed polypropylene built in the lid body 8, a cylindrical heat insulating material 11 located on the outer periphery of the container 3, a body 1 located on the outer periphery of the heat insulating material 11, And an upper frame 4 placed thereon.

そして、前記容器３はその開口周縁部が上枠４に装備され、容器３の開口周縁部と蓋体８間には、シリコーンゴムなど弾性体のパッキンが施されシール部５を構成しているものである。   The opening periphery of the container 3 is mounted on the upper frame 4, and an elastic packing such as silicone rubber is applied between the opening periphery of the container 3 and the lid 8 to form the seal portion 5. Is.

また、前記断熱材１１は、特に、その構成が限定されるものでないが、本参考例においては、断熱材１１を真空断熱材としているものである。これは、真空部１２を外袋１３で覆い、真空部１２はヒュームドシリカやパーライトなどの無機粉末、あるいはグラスウー
ルなどの無機繊維、硬質ウレタンフォーム、発泡フェノール樹脂などの芯材が充填されており、外袋１３はガスバリア性を有した樹脂フィルム、樹脂・金属箔ラミネートフィルム（例えば、ナイロン・ＰＥＴ・アルミ箔・無延伸ポリプロピレン）などで構成され、内部を減圧して封止したものである。通常、真空断熱材は平板状なるものなので、容器３への装着を可能とするため、３本ローラーなどを用いて筒状に加工している。 Moreover, although the structure in particular is not limited, the said heat insulating material 11 uses the heat insulating material 11 as a vacuum heat insulating material in this reference example. This is because the vacuum part 12 is covered with an outer bag 13, and the vacuum part 12 is filled with an inorganic powder such as fumed silica or perlite, or an inorganic fiber such as glass wool, a hard urethane foam, or a core material such as foamed phenol resin. The outer bag 13 is made of a resin film having gas barrier properties, a resin / metal foil laminate film (for example, nylon, PET, aluminum foil, unstretched polypropylene), and the like, and is sealed by reducing the inside. Usually, since a vacuum heat insulating material becomes flat form, in order to make the mounting | wearing to the container 3 possible, it is processed into the cylinder shape using 3 rollers.

ここで、断熱材１１は、その上端部を容器３と蓋体８間のシール部５よりも上方に配設しているものである。また、断熱材１１の上端部は、蓋体８の下面８ａよりも上方に配設している。さらに、断熱材１１の上端部は、蓋体８に内蔵された蓋断熱材９の下面よりも上方に配設しているものである。   Here, the heat insulating material 11 has an upper end disposed above the seal portion 5 between the container 3 and the lid 8. Further, the upper end portion of the heat insulating material 11 is disposed above the lower surface 8 a of the lid 8. Furthermore, the upper end portion of the heat insulating material 11 is disposed above the lower surface of the cover heat insulating material 9 built in the cover body 8.

なお、断熱材１１と容器３との間には隙間１４を設け、その一部には対流防止部材１６が配設されている。ここでは、対流防止部材１６として発泡メラミンなどを用いているが、１００℃以上の耐熱性のある断熱材であれば何を用いてもよい。   Note that a gap 14 is provided between the heat insulating material 11 and the container 3, and a convection preventing member 16 is disposed in a part thereof. Here, foamed melamine or the like is used as the convection preventing member 16, but any heat insulating material having heat resistance of 100 ° C. or higher may be used.

次に、本参考例における作用を説明する。   Next, the operation of this reference example will be described.

例示した電気湯沸かし器は、一般によく知られているように、蓋体８を開放して容器３内に被収容物（水）２を入れ、被収容物２を加熱・保温し、ポンプの駆動により、湯を適宜吐出させることができるものである。   In the illustrated electric water heater, as is generally well known, the lid 8 is opened, the object (water) 2 is placed in the container 3, the object 2 is heated and kept warm, and the pump is driven. The hot water can be discharged appropriately.

ここで、本参考例においては、被収容物２の保温中、容器３の外周部に配置した断熱材１１および蓋体８内部の蓋断熱材９により、容器３側面および容器３上方からの放熱を抑制できるものである。断熱材１１を真空断熱材（真空断熱材の熱伝導率＝０．００３〜０．００８Ｗ／ｍＫ）とすれば、保温時の電力量を大幅に低減でき経済性が高く、しかも製品重量を増加させることなく、組立て作業性・使い勝手を良化できるものである。   Here, in this reference example, during the heat insulation of the object 2, heat is dissipated from the side surface of the container 3 and from above the container 3 by the heat insulating material 11 disposed on the outer peripheral portion of the container 3 and the lid heat insulating material 9 inside the lid 8. Can be suppressed. If the heat insulating material 11 is a vacuum heat insulating material (thermal conductivity of the vacuum heat insulating material = 0.003 to 0.008 W / mK), the amount of electric power during heat insulation can be greatly reduced, and the cost is high, and the product weight is increased. This makes it possible to improve the assembly workability and usability.

そして、断熱材１１の上端部は容器３と蓋体８のシール部５よりも上方に配設し、シール部５の外周を覆っている。さらに、断熱材１１の上端部は、蓋体８の下面８ａよりも上方で、しかも蓋体８に内蔵された蓋断熱材９の下面よりも上方に配設しているものである。これにより、蓋体８と容器３のシール部５はパッキンで接しているだけであるので、熱が漏洩しやすいが、断熱材１１で外周が覆われ、蓋体８と蓋断熱材９で内周を覆うことで、シール部５が外周と内周で挟み込まれる構成となり、シール部５からの熱漏洩を低減することができ、従来の構成よりも少量の保温電力量で容器３中の被収容物２を保温することができる。   And the upper end part of the heat insulating material 11 is arrange | positioned above the seal | sticker part 5 of the container 3 and the cover body 8, and has covered the outer periphery of the seal | sticker part 5. FIG. Further, the upper end portion of the heat insulating material 11 is disposed above the lower surface 8 a of the lid body 8 and further above the lower surface of the lid heat insulating material 9 built in the lid body 8. Thereby, since the lid 8 and the seal portion 5 of the container 3 are only in contact with the packing, heat is likely to leak, but the outer periphery is covered with the heat insulating material 11, and the lid 8 and the lid heat insulating material 9 By covering the periphery, the seal portion 5 is sandwiched between the outer periphery and the inner periphery, heat leakage from the seal portion 5 can be reduced, and the amount of heat retained in the container 3 can be reduced with a smaller amount of heat retention than in the conventional configuration. The contents 2 can be kept warm.

また、断熱材１１と容器３の間には対流防止部材１６が配設され、断熱材１１と容器３の間には隙間１４が設けられ、断熱材１１と容器３が直接接触せず、空気層を介して熱が移動するため、さらに断熱効果を向上することができる。この場合、断熱材１１への直接の熱伝達が無く、断熱材１１の表面温度も下がるため、断熱材表面の熱伝導量も低減することができる。したがって、真空断熱材を用いた場合、平均温度の低下により侵入ガス量が低減するので、真空断熱材の経時信頼性が向上し、省エネ性能の劣化を低減することができる。   Further, a convection preventing member 16 is disposed between the heat insulating material 11 and the container 3, and a gap 14 is provided between the heat insulating material 11 and the container 3, so that the heat insulating material 11 and the container 3 are not in direct contact with each other, and air Since heat moves through the layers, the heat insulation effect can be further improved. In this case, there is no direct heat transfer to the heat insulating material 11, and the surface temperature of the heat insulating material 11 is also lowered, so that the amount of heat conduction on the surface of the heat insulating material can also be reduced. Therefore, when the vacuum heat insulating material is used, the amount of intrusion gas is reduced due to a decrease in the average temperature, so that the reliability over time of the vacuum heat insulating material is improved and the deterioration of the energy saving performance can be reduced.

なお、本参考例では、真空断熱材は外袋１３と芯材が充填された真空部１２で構成されるものとしたが、特に限定するものではなく、内部を減圧して封止した２重層のステンレスなどで構成される断熱材であっても同様の効果を得ることができる。また、容器３の形状としては、円柱や多角柱形状をなし、断熱材１１は容器３に沿うような円柱または多角柱形状が好ましいが、特に限定するものではない。   In this reference example, the vacuum heat insulating material is composed of the outer bag 13 and the vacuum portion 12 filled with the core material. However, the vacuum heat insulating material is not particularly limited, and a double layer sealed by reducing the pressure inside. The same effect can be obtained even with a heat insulating material made of stainless steel. In addition, the shape of the container 3 is preferably a columnar or polygonal column shape, and the heat insulating material 11 is preferably a columnar or polygonal column shape along the container 3, but is not particularly limited.

本参考例では、断熱機器として電気湯沸かし器を例示したが、特に、これに限定するものではなく、炊飯器、保温調理器、給湯器などであってもよく、また、電気・ガス機器に限らず貯湯容器など保温を目的とする機器類であれば適用することが可能であり、保温効果の向上を図ることができるものである。   In this reference example, an electric water heater has been exemplified as the heat insulating device, but it is not particularly limited to this, and may be a rice cooker, a heat-retaining cooker, a water heater, etc., and is not limited to an electric / gas device. It can be applied to any device such as a hot water storage container for the purpose of keeping heat, and the heat keeping effect can be improved.

FIG. 3 shows a main part of an electric water heater in Reference Example 2 of the present invention. The same elements as those in Reference Example 1 are denoted by the same reference numerals, and description thereof is omitted.

本参考例においては、断熱材１１を第１の断熱材１１ａと第２の断熱材１１ｂから構成し、第１の断熱材１１ａは容器３と蓋体８間のシール部５よりも下方位置に配設し、第２の断熱材１１ｂは容器３と蓋体８間のシール部５よりも上方位置から第１の断熱材１１ａの上端部とオーバーラップする下方位置まで配設したものである。   In this reference example, the heat insulating material 11 is composed of a first heat insulating material 11 a and a second heat insulating material 11 b, and the first heat insulating material 11 a is positioned below the seal portion 5 between the container 3 and the lid 8. The second heat insulating material 11b is disposed from a position higher than the seal portion 5 between the container 3 and the lid 8 to a lower position overlapping the upper end portion of the first heat insulating material 11a.

これにより、第１、第２の断熱材１１ａ、１１ｂで、最も熱漏洩しやすい容器３と蓋体８間のシール部５の上、下方位置を断熱するため、断熱効果を向上することができ、少量の保温電力量で容器３中の被収容物２を保温することができるものである。   Accordingly, the first and second heat insulating materials 11a and 11b insulate the lower position on the seal portion 5 between the container 3 and the lid body 8 that is most likely to leak heat, so that the heat insulating effect can be improved. The to-be-contained object 2 in the container 3 can be kept warm with a small amount of heat retaining power.

FIG. 4 shows a main part of an electric water heater in Reference Example 3 of the present invention. The same elements as those in Reference Examples 1 and 2 are denoted by the same reference numerals and description thereof is omitted.

本参考例においては、断熱材１１を構成する第１の断熱材１１ａと第２の断熱材１１ｂは、芯材の充填されていない折返し部１５を設けて一体化したものである。そして、第１の断熱材１１ａは容器３と蓋体８間のシール部５よりも下方位置に配設し、第２の断熱材１１ｂは容器３と蓋体８間のシール部５よりも上方位置から第１の断熱材１１ａの上端部とオーバーラップする下方位置まで配設したものである。   In this reference example, the 1st heat insulating material 11a and the 2nd heat insulating material 11b which comprise the heat insulating material 11 provide the folding | returning part 15 with which the core material is not filled, and are integrated. And the 1st heat insulating material 11a is arrange | positioned in the downward position rather than the seal part 5 between the container 3 and the cover body 8, and the 2nd heat insulating material 11b is above the seal part 5 between the container 3 and the cover body 8. It arrange | positions from the position to the downward position which overlaps with the upper end part of the 1st heat insulating material 11a.

これにより、第１、第２の断熱材１１ａ、１１ｂが一体化され断熱材１１の扱いが容易で、かつ、参考例２と同様、断熱効果を向上することができ、少量の保温電力量で容器３中の被収容物２を保温することができる。   Thereby, the 1st, 2nd heat insulating material 11a, 11b is integrated, the handling of the heat insulating material 11 is easy, and, similarly to the reference example 2, the heat insulating effect can be improved, and with a small amount of heat insulation power. The to-be-contained object 2 in the container 3 can be kept warm.

（参考例４）
図５は、本発明の参考例４における電気湯沸かし器を示すものである。参考例１、２と同一要素については同一符号を付して説明を省略する。 (Reference Example 4)
FIG. 5 shows an electric water heater in Reference Example 4 of the present invention. The same elements as those in Reference Examples 1 and 2 are denoted by the same reference numerals and description thereof is omitted.

本参考例においては、断熱材１１は第１の断熱材１１ａとこれと折返し部１５を設けて一体化した第２の断熱材１１ｂから構成し、これら第１、第２の断熱材１１ａ、１１ｂを芯材の充填されていない折返し部１５で折り返して２重に重ねて容器３の外周部に位置させたものである。そして、外周側に位置する第２の断熱材１１ｂの上端部は、蓋体８と容器３のシール部５よりも上方に配設したものである。   In this reference example, the heat insulating material 11 is composed of a first heat insulating material 11a and a second heat insulating material 11b integrated with the first heat insulating material 11a, and the first and second heat insulating materials 11a and 11b. Is folded at the folded portion 15 that is not filled with the core material, and is overlapped and positioned on the outer peripheral portion of the container 3. And the upper end part of the 2nd heat insulating material 11b located in an outer peripheral side is arrange | positioned above the cover 8 and the seal part 5 of the container 3. FIG.

これにより、断熱材１１を２重に重ねで容器３側面の断熱効力を２倍にすることができとともに、外周側の断熱材１１ｂが蓋体８と容器３のシール部５を覆うため、さらに断熱効果を向上することができ、少量の保温電力量で容器３中の被収容物２を保温することができる。   Accordingly, the heat insulating material 11 can be doubled to double the heat insulating effect on the side surface of the container 3, and the outer heat insulating material 11 b covers the lid 8 and the seal portion 5 of the container 3. The heat insulation effect can be improved, and the to-be-contained object 2 in the container 3 can be kept warm with a small amount of heat retaining power.

（実施の形態１）
図６は、本発明の実施の形態１における電気湯沸かし器の要部を示すものである。参考例１と同一要素については同一符号を付して説明を省略する。 (Embodiment 1)
FIG. 6 shows a main part of the electric water heater according to the first embodiment of the present invention. The same elements as those in Reference Example 1 are denoted by the same reference numerals, and description thereof is omitted.

本実施の形態においては、容器３の上端部よりも下方位置で容器３の内側面部に凸部３ａを形成することにより蓋体８とのシール部５を設けたものである。そして、断熱材１１は真空断熱材とし、その真空部上端を容器３と蓋体８間のシール部５よりも上方に配設した。さらに、蓋体８の下面８ａおよび蓋体８に内蔵された蓋断熱材９の下面は、シール部５よりも下方に配設したものである。   In the present embodiment, the sealing portion 5 with the lid 8 is provided by forming the convex portion 3 a on the inner side surface portion of the container 3 at a position below the upper end portion of the container 3. The heat insulating material 11 was a vacuum heat insulating material, and the upper end of the vacuum part was disposed above the seal part 5 between the container 3 and the lid 8. Furthermore, the lower surface 8 a of the lid 8 and the lower surface of the lid heat insulating material 9 built in the lid 8 are disposed below the seal portion 5.

これにより、蓋体８と容器３のシール部５は断熱材１１で覆われるため、シール部５からの熱漏洩が低減でき、少量の保温電力量で容器３中の被収容物２を保温することができる。特に、断熱材１１は真空断熱材とし、その真空部上端を容器３と蓋体８間のシール部５よりも上方に配設したことにより、真空断熱材の実質的に断熱効果の高い真空部で蓋体８と容器３のシール部５を覆うため、シール部５からの熱漏洩が低減できる。また、蓋体８の下面８ａを、容器３と蓋体８のシール部５よりも下方に配設したことにより、シール部５よりも下方で蓋体８下面が容器３内の熱の上昇を抑え、さらにシール部５外周が断熱材１１に覆われるため、シール部５からの熱漏洩が低減できる。特に、蓋体８に内蔵された蓋断熱材９の下面を、シール部５よりも下方に配設したことにより、シール部５よりも下方で蓋体８下面が容器３内の熱の上昇を抑え、さらに実質的に断熱効力の高い蓋体８の蓋断熱材９とシール部５外周の断熱材１１をオーバーラップさせることで、さらに断熱効力を上げることができる。   As a result, since the lid 8 and the seal portion 5 of the container 3 are covered with the heat insulating material 11, heat leakage from the seal portion 5 can be reduced, and the object 2 in the container 3 can be kept warm with a small amount of heat retention power. be able to. In particular, the heat insulating material 11 is a vacuum heat insulating material, and the upper end of the vacuum part is disposed above the seal part 5 between the container 3 and the lid 8, so that the vacuum heat insulating material has a substantially high heat insulating effect. Since the cover 8 and the seal part 5 of the container 3 are covered, heat leakage from the seal part 5 can be reduced. Further, since the lower surface 8 a of the lid 8 is disposed below the seal portion 5 between the container 3 and the lid 8, the lower surface of the lid 8 lowers the heat in the container 3 below the seal portion 5. Further, since the outer periphery of the seal portion 5 is covered with the heat insulating material 11, heat leakage from the seal portion 5 can be reduced. In particular, since the lower surface of the lid heat insulating material 9 built in the lid body 8 is disposed below the seal portion 5, the lower surface of the lid body 8 increases the heat in the container 3 below the seal portion 5. Further, the heat insulation effect can be further increased by overlapping the cover heat insulating material 9 of the lid body 8 having a substantially high heat insulation effect and the heat insulation material 11 on the outer periphery of the seal portion 5.

以上のように、本発明にかかる断熱機器は、容器と蓋体のシール部の側面からの熱漏洩を大幅に低減し、省エネ効果の高いものとすることができるので、炊飯器、保温調理器、給湯器あるいは湯沸かし器など保温を目的とする機器の断熱強化に適用できる。   As described above, the heat insulating device according to the present invention can greatly reduce the heat leakage from the side surfaces of the seal part of the container and the lid, and can have a high energy saving effect. It can be applied to heat insulation reinforcement of equipment for the purpose of keeping warm, such as a water heater or a water heater.
