本考案の基本となる構成を、第１図及び第２図
に基づいて説明する。
The basic structure of the present invention will be explained based on FIGS. 1 and 2.
第２図に示す１は、炊飯器用の内なべで、底板
１ａの外周縁より、上端開口縁１ｃが若干拡径す

状周壁１ｂの外周面には、遠赤外線吸収膜２が形
成されている。 Reference numeral 1 shown in FIG. 2 is an inner pot for a rice cooker, which has a bottomed cylindrical shape with a continuous annular circumferential wall 1b whose upper opening edge 1c is slightly larger in diameter than the outer circumferential edge of a bottom plate 1a. A far-infrared absorbing film 2 is formed on the surface.
この遠赤外線吸収膜２は、遠赤外線放射物質と

に、例えば吹き付けた後、焼き付けて形成されて
いる。 This far-infrared absorption film 2 is made of metal oxides such as zirconia (ZrO 2 ), zircon (ZrO 2・SiO 2 ), titania (TiO 2 ), and alumina (Al 2 O 3 ), which are known as far-infrared emitting substances. It is formed by, for example, spraying a coating material that is a mixture of ceramic material and paint onto the outer peripheral surface of the inner pot and then baking it.

性質が優れてたものとして一般に利用されている
が、物質の光の放射と選択吸収のスペクトルは同
一であるため、前記波長の遠赤外線の吸収媒体と
して有効なものである。 The far-infrared emitting material used for this far-infrared absorbing film 2 is generally used as a material with excellent properties of emitting far-infrared rays with a wavelength of 1 to 10 μm, but the spectrum of light emission and selective absorption of the material is Since they are the same, it is effective as a medium for absorbing far infrared rays of the above wavelength.
第１図に示す３は電気炊飯器であり、上面が開
口する有底円筒状の本体４と、この本体４の外周
上縁部に一端が開閉自在に枢着された把手５、及
び外ぶた６からなつている。 Reference numeral 3 shown in FIG. 1 is an electric rice cooker, which includes a bottomed cylindrical main body 4 with an open top, a handle 5 with one end pivotally attached to the upper edge of the outer periphery of the main body 4 so as to be able to open and close freely, and an outer lid. It consists of 6.
本体４は、アルミニウムからなり、かつ内なべ
１よりやや大径の内筒８と、それよりさらに大径
の外筒９との間へ充填材７を充填してなり、内筒
８は、内なべの収納室１０を形成している。 The main body 4 is made of aluminum and has a filling material 7 filled between an inner cylinder 8 having a slightly larger diameter than the inner pot 1 and an outer cylinder 9 having an even larger diameter. A storage chamber 10 for pans is formed.
内筒８の底板８ａの下面には、環状をなす熱源
として、電気ヒーター１１が設けられている。 An electric heater 11 is provided on the lower surface of the bottom plate 8a of the inner cylinder 8 as an annular heat source.
外ぶた６も同様に、アルミニウムからなり、か
つ間隙を有する逆皿状の天板１３及び外板１４の
間に、断熱材１２を充填してなり、天板１３に
は、逆皿状の内ぶた１５が着脱自在に取付けられ
ている。 Similarly, the outer lid 6 is made of aluminum, and a heat insulating material 12 is filled between an inverted dish-shaped top plate 13 and an outer plate 14 having a gap. A lid 15 is detachably attached.
１６は、内なべ内の飯の炊きあがりを検知する
ための検知手段である。 16 is a detection means for detecting the completion of cooking of the rice in the inner pot.
なお、図示はしていないが、本体４には、炊飯
スイツチ、電源コード等が設けられている。 Although not shown, the main body 4 is provided with a rice cooker switch, a power cord, and the like.
炊飯をするには、内なべ１に、洗つた米及び適
量の水を入れ、これを、本体４の内なべ収納室１
０に入れた後、電気ヒーター１１に通電する。 To cook rice, put washed rice and an appropriate amount of water in the inner pot 1, and then pour this into the inner pot storage chamber 1 of the main body 4.
After setting the temperature to 0, the electric heater 11 is energized.
電気ヒーター１１の熱は、内筒８の底板８ａを
介して、伝導により内なべ１に伝わり、これと同
時に、内筒８自身も加熱されて、その温度が上昇
する。 The heat from the electric heater 11 is transmitted to the inner pot 1 by conduction via the bottom plate 8a of the inner cylinder 8, and at the same time, the inner cylinder 8 itself is also heated and its temperature rises.
しかし、内筒８と内なべ１の外周面との間には
間隙が形成されているため、内なべ１に伝導され
る熱の量は少なく、しかも内筒８の外側は断熱材
７で覆われているため、内筒８には熱が多量に蓄
積されて、内筒８は高温になる。 However, since a gap is formed between the inner cylinder 8 and the outer peripheral surface of the inner pot 1, the amount of heat conducted to the inner pot 1 is small, and the outside of the inner cylinder 8 is covered with a heat insulating material 7. As a result, a large amount of heat is accumulated in the inner cylinder 8, and the inner cylinder 8 becomes high in temperature.
このように高温となつた内筒８の内周面から出
る赤外線は、内なべ１の外周面に形成された遠赤
外線吸収膜２に吸収される。 The infrared rays emitted from the inner circumferential surface of the inner cylinder 8 which has reached a high temperature in this way is absorbed by the far infrared absorbing film 2 formed on the outer circumferential surface of the inner pot 1.
従つて、内なべ１内の米と水には、従来の底か
らの加熱に加えて、側方からも加熱が行なわれ、
従来に比して短時間で、炊飯を完了することがで
きる。 Therefore, the rice and water in the inner pot 1 are heated from the sides in addition to the conventional heating from the bottom.
Rice cooking can be completed in a shorter time than conventional methods.
本考案は、上記のような炊飯器において、内筒
８の赤外線放射効果をより高めるようにしたもの
で、第３図に示すように、内筒８の内周面８ｂ

膜２と同じ物質からなる遠赤外線放射膜１７を設
けてある。 The present invention is a rice cooker as described above, in which the infrared radiation effect of the inner cylinder 8 is further enhanced.As shown in FIG.
A far-infrared emitting film 17 made of the same material as the far-infrared absorbing film 2 provided on the outer peripheral surface 1b of the inner pot 1 is provided.
これによつて、高温側と低温側に、同じスペク
トルを有する遠赤外線放射膜１７と遠赤外線吸収
膜２が向きあうため、熱の伝導効率はきわめて高
められる。 As a result, the far-infrared radiation film 17 and the far-infrared absorption film 2, which have the same spectrum, face each other on the high-temperature side and the low-temperature side, so that the heat conduction efficiency is extremely improved.
上述した実施例では、自動炊飯器は電気炊飯器
として説明したが、本考案は、ガス炊飯器につい
て適用できることは勿論である。 In the embodiments described above, the automatic rice cooker was explained as an electric rice cooker, but the present invention can of course be applied to a gas rice cooker.
本考案によると、内なべの外周面に遠赤外線吸

According to this invention, since a far-infrared absorbing film is formed on the outer circumferential surface of the inner pot, when cooking rice, far-infrared rays are absorbed from the inner circumferential surface of the inner cylinder of the main body, and this is used as heat for cooking rice. Therefore, you can cook rice efficiently in a short time.
また、炊飯器本体の内筒内周面に、遠赤外線放
