本発明は、外部から内容液４面及び内容液の温度が観察
でき、同時に内容液の温度を長時間にわたり保持するこ
とができる保温槽に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat-retaining tank in which four sides of the liquid and the temperature of the liquid can be observed from the outside, and at the same time, the temperature of the liquid can be maintained for a long period of time.
一般に容器と呼ばれているものは外部から内容液量と液
温か直視でき、しかも内容液の温度を保持できれば便利
であることはいうまでもない。It goes without saying that what is generally called a container would be convenient if the amount and temperature of the liquid inside could be directly observed from the outside and the temperature of the liquid inside could be maintained.
内容液の保温という面からみれば、従来内壁と外壁との
間に空間を形成させ、該空間で断熱効果をもたせた容器

シも熱伝導率は小さいもので、それなりの断熱効果を期
待することができるが、そｎでも対流を起こすと意外に
熱を運ぶものであり、また輻射によってもかな９の熱が
移動するものである。From the perspective of keeping the liquid inside warm, conventional containers have been created in which a space is formed between an inner wall and an outer wall, and the space has a heat insulating effect. Air placed in a space has a low thermal conductivity compared to any solid insulation material, and can be expected to have a certain insulation effect, but when convection occurs, it surprisingly carries heat, and Kana 9's heat is also transferred by radiation.
そこで、内壁と外壁との空間を真壁にするとともに外壁
内側と内壁外測に輻射熱を反射させることにより、熱遮
断をする金属鏡（銀メッキ）を設け、より完全な断熱効
果を狽った魔法ビンがあｐ。Therefore, by making the space between the inner wall and the outer wall a solid wall, and by reflecting the radiant heat on the inner side of the outer wall and the outer wall, we installed a metal mirror (silver plated) that blocks heat, thereby achieving a more complete insulation effect. The bottle is up.
用途に応じて現在多数使用されている。Many types are currently used depending on the purpose.
しかしながら、上記魔法ビンは外壁内側及び内壁外側が

めにはその都度蓋を開けるか又は特別な液面レベル計及
び温度計等全付加して内容液の液量を検知するしか手段
がなかった。However, since the above-mentioned thermos bottle is covered with opaque metal mirrors on the inside of the outer wall and the outside of the inner wall, the amount of liquid inside can be controlled by external force.
The liquid temperature cannot be directly detected. In order to detect the liquid volume and temperature of the liquid content, the only way to do so is to open the lid each time or to add a special liquid level meter, thermometer, etc. to detect the liquid level of the liquid content.
本発明は上記従来の課題に鑑みなされたもので。The present invention has been made in view of the above-mentioned conventional problems.
その目的は外部から内容液の液面と液温が容易に観察で
き、同時に内容液の液温を長時間にわたり保持すること
ができる実用価値の晶い便利な保温槽を提供するもので
ある。The purpose is to provide a practical and convenient heat-retaining tank that allows the liquid level and temperature of the liquid content to be easily observed from the outside, and at the same time maintains the temperature of the liquid content for a long period of time.

を特徴とする。In other words, the heat-retaining tank of the present invention is a heat-retaining tank in which a transparent outer wall and an inner wall are integrally connected, a vacuum chamber is formed between the outer wall and the inner wall, and a space surrounded by the inner wall is configured as a container. The vacuum chamber is characterized in that at least one surface of the outer wall and the inner wall is coated with a transparent heat ray shielding film, and further a temperature indicating mechanism is disposed on a part of the side surface of the inner wall in the vacuum chamber.

が被覆しであるので、内容液からの熱線は保温槽の内側
に反射され、容器外には熱放散されないので、内容液の
温度を長時間維持することができる。In the heat-retaining tank of the present invention, the container itself is made of a transparent material, so the level of the liquid inside can be easily observed from the outside. Moreover, since the inner and outer walls are integrally connected and the space between them is used as a vacuum chamber, heat dissipation due to heat conduction and convection can be prevented. Furthermore, since the inner surface of the vacuum chamber is coated with a transparent heat ray shielding film, the heat rays from the content liquid are reflected inside the heat insulating tank and are not dissipated outside the container, so the temperature of the content liquid can be reduced. Can be maintained for a long time.
１だ、前記外壁又は内壁の内側面（臭突室側）上には内
容液の液温変化を表示する示温機構があるので、外部か
ら直接内容液の液温を検知できる。1. Since there is a temperature indicator mechanism on the inner surface (on the side of the odor chamber) of the outer wall or the inner wall to display the temperature change of the content liquid, the temperature of the content liquid can be directly detected from the outside.
本発明において、保温槽に用いた外壁及び内壁は内容液

A substance that reflects heat rays emitted from the liquid inside is used. Examples of such substances include the following.

'l'0 film] is one example. This ITO
FIG. 1 shows the relationship between the transmittance (T), absorption rate (A), and reflectance (it) of the film for each wavelength.

過率は大である。しかし、内容液から放射される波長の
長い熱線（約５ ｕｍ以上）については透過率は小さく
、逆に反射率が非常に高いことを示す。From FIG. 1, the ITO film has a high transmittance in the short wavelength visible light region. However, the transmittance of heat rays with long wavelengths (approximately 5 um or more) emitted from the liquid content is low, and on the contrary, the reflectance is extremely high.

るものとすることができる。The above oxides cannot be expected to have a great effect when used as a single-layer thin film, but by forming each thin film to a thickness that satisfies the conditions for interference and reflection of heat rays, and laminating multiple layers, it is possible to create a film with a large heat insulating effect. This makes it possible to greatly increase the heat retention effect of the content liquid.

的手段がある。The above-mentioned heat ray shielding film is a very thin film, and needs to have a strong adhesion strength to the extent that the thin film does not easily peel off. Methods for forming thin films with good adhesion include physical methods such as sputtering, vacuum evaporation, and ion plating, and chemical methods in which oxides or metals are precipitated by oxidizing, dispersing, or hydrolyzing organic metals. There is a means.

It is preferable to form it on the side wall soil. In order to further ensure a better effect, it is desirable to provide it on both the inner surface of the outer wall and the inner wall (vacuum chamber 011).

合物を主成分とする示温剤。In the present invention, the temperature indicating mechanism is one having a function of indicating a state of change in the temperature of the content liquid. An example of such a temperature indicating mechanism is a temperature indicating agent whose main component is a metal complex mixture that changes color tone reversibly in response to changes in liquid temperature.

のである。There are two types of heat dissipation: heat rays and heat conduction. The heat ray shielding film described above is intended to prevent heat dissipation by reflecting heat rays, but the heat ray shielding film alone cannot prevent heat dissipation due to thermal conduction. The vacuum chamber has the role of shielding heat conduction from the liquid inside and also preventing heat dissipation due to convection.
The heat retention ability of the liquid content can be made more reliable.
以下１図面を参照しながら９本発明の実施例を詳細に説

3A was coated by sputtering to form a hot wire zeolite film.
保温槽１の土部開口部１１には断熱性がよく加工性のよ
いコルク材で形成した円盤状の蓋体５を嵌着し、密閉で
きるようにする。A disc-shaped lid 5 made of a cork material with good heat insulation and workability is fitted into the soil opening 11 of the heat-retaining tank 1 so that it can be sealed tightly.

該槽内の湯の液面が容易に観察することができる。However, if hot water is poured into the heating tank 1 of the non-embodiment and left in a state where it is sealed with the lid 5, the double wall formed by the outer wall 2 and the inner wall 6 of the heating tank 1 will be formed of a transparent glass material. Moreover, since the top 24° 66 of the inner surface of the vacuum chamber 4 is a transparent iTO film, the liquid level of the hot water in the tank can be easily observed from the outer side of the heat-retaining tank without removing the lid 5. .

液の液温が内壁３を熱伝達してきた熱温の作用によシ変
色する。Moreover, since the temperature indicating mechanism 6 is disposed on a part of the surface of the inner side 54 of the inner wall 6 of the vacuum chamber 4, the temperature indicating mechanism 6 is capable of controlling the temperature of the liquid content transferred to the inner wall 3. It changes color due to the action.
かかる示温機構６における変色を外部より観察すること
により、内容液の液温を検知できる。By observing the color change in the temperature indicating mechanism 6 from the outside, the temperature of the content liquid can be detected.
また、槽内の湯は熱線（約８〜１０ ｕｍ ）を放射す
るが、ＩＴＯ膜３ｂの反射効果により該熱線はほとんど
槽内側に反射され、外部に放出されることかない。Further, although the hot water in the tank emits heat rays (approximately 8 to 10 um), most of the heat rays are reflected inside the tank due to the reflection effect of the ITO film 3b, and are not emitted to the outside.

Since the space formed by the outer wall 2 and the inner wall 5 serves as the vacuum chamber 4, heat conduction and heat dissipation due to convection can be blocked by the vacuum chamber 4.
さらに、あたためられたガラス内壁６α及びＩＴＯ膜３
ｂから発生する熱線は、外壁２の内側面２鵡上に形成し
たＩＴＯ膜２ｂの熱線反射効果によシ遮断される。Furthermore, the heated glass inner wall 6α and the ITO film 3
The heat rays generated from the outer wall 2 are blocked by the heat ray reflection effect of the ITO film 2b formed on the inner surface 2b of the outer wall 2.
しかして、槽内の湯は槽を形成する壁の二重。Therefore, the hot water in the tank is double walled in the walls that form the tank.
三重の熱遮断効果により、槽外への熱放散が妨げられ、
長時間にわたり湯温を維持することができる。The triple heat shielding effect prevents heat dissipation to the outside of the tank.
The water temperature can be maintained for a long time.

The configuration is shown in FIG. The thermometer 7 has a structure such that the contact area with the inside of the vacuum chamber, that is, with the outer surface 3α of the inner wall 6 is large.
本実施例の保温槽１は上記のように構成しであるので、
外部側面より温度計が内容液温を示していることが容易
に観察できる。Since the heat retention tank 1 of this embodiment is configured as described above,
It can be easily observed from the outside side that the thermometer indicates the temperature of the liquid inside.
