Description

本発明は、食品や生活用品を急速に冷却するのに好適な急速冷却器に関する。 The present invention relates to a rapid cooler suitable for rapidly cooling foods and daily necessities.

従来、食品や生活用品を急速に冷却する方法としては、あらかじめ冷却しておいた蓄冷材を冷却対象物に接触させる方法や、冷凍庫や冷凍室に冷却対象物をそのまま入れる方法が一般的である。 Conventionally, as a method of rapidly cooling foods and daily necessities, a method of bringing a pre-cooled cold storage material into contact with a cooling object or a method of putting the cooling object in a freezer or a freezing chamber as it is is common. ..

特許文献１および特許文献２では、容器の側壁や底面に蓄冷材を組み込んだ冷却機器が提案されており、この容器に冷却対象物を入れることで、冷却対象物と蓄冷材を接触させて冷却を行うものとなっている。 Patent Document 1 and Patent Document 2 propose a cooling device in which a cold storage material is incorporated in the side wall or bottom surface of a container. By putting a cooling object in this container, the cooling target and the cold storage material are brought into contact with each other for cooling. Is to be done.

特許文献１および特許文献２では、容器の側壁や底面に蓄冷材を組み込んだ冷却機器が提案されているが、これらの機器では冷却対象物と蓄冷材を隔てる部材における蓄冷材側の表面形状が平面的である。蓄冷材の熱伝導率は金属と比較して小さく、熱伝導の距離が増加すると急速な冷却に十分な熱量を伝導できなくなるため、蓄冷材の冷熱はこの部材に近い範囲のものしか効率よく利用できない。蓄冷材の冷熱を広範囲から効率よく利用するためには、前記の平面的形状を凹凸のある形状、すなわち表面積を大きくすることが効果的である。 Patent Document 1 and Patent Document 2 propose cooling devices in which a cold storage material is incorporated in the side wall or bottom surface of the container, but in these devices, the surface shape on the cold storage material side of the member separating the cooling object and the cold storage material is It is flat. The thermal conductivity of the cold storage material is smaller than that of metal, and as the distance of heat conduction increases, it becomes impossible to conduct a sufficient amount of heat for rapid cooling. Can not. In order to efficiently utilize the cold heat of the cold storage material from a wide range, it is effective to change the planar shape to an uneven shape, that is, to increase the surface area.

冷凍庫や冷凍室に冷却対象物をそのまま入れる冷却方法では、冷却作用のほとんどが気体からの熱伝達によるものであるため、固体や液体から熱伝達を行う方法と比較して、急速な冷却を行いにくい。 In the cooling method in which the object to be cooled is put into the freezer or freezer as it is, most of the cooling action is due to heat transfer from gas, so the cooling is performed more rapidly than the method in which heat transfer is performed from solid or liquid. Hateful.

本発明は、蓄冷材の冷熱を広範囲から効率よく利用し、かつ、冷却対象物の側面と底面から、場合によっては上面からも、固体からの熱伝達による冷却作用を与えることで、食品や生活用品を急速に冷却する、急速冷却器を提供することにある。 The present invention efficiently utilizes the cold heat of the cold storage material from a wide range, and also provides a cooling action by heat transfer from a solid from the side surface and the bottom surface of the object to be cooled, and in some cases, from the top surface, thereby providing a cooling effect to food and daily life. The purpose is to provide a quick cooler that cools supplies rapidly.

冷却対象物またはアタッチメント５を挿入する挿入孔２があり、挿入孔２以外の表面積は挿入孔２の表面積の１．５倍以上とした、金属製の伝熱板１と、伝熱板１の挿入孔２以外の表面を内包した蓄冷材充填用空間を提供するケース４と、この空間に充填した蓄冷材３と、で構成する本体、および、挿入孔２に挿入して使用する、金属製のアタッチメント５、からなる急速冷却器とする。 A metal heat transfer plate 1 and a heat transfer plate 1 having an insertion hole 2 into which an object to be cooled or an attachment 5 is inserted and having a surface area other than the insertion hole 2 1.5 times or more the surface area of the insertion hole 2. A main body composed of a case 4 for providing a space for filling a cold storage material containing a surface other than the insertion hole 2, a cold storage material 3 filled in this space, and a metal product inserted into the insertion hole 2. A rapid cooler consisting of the attachment 5 of the above.

本器の使用には、本器全体が十分に冷却されている必要がある。本器の使用方法は、冷却対象物を挿入孔２に挿入する。 To use the instrument, the entire instrument must be sufficiently cooled. The method of using this instrument is to insert the object to be cooled into the insertion hole 2.

伝熱板１の材質である金属の熱伝導率は一般的に大きいため、冷却対象物の熱は効率よく伝熱板１へ移動する。しかしながら、金属は水に比べて比熱容量が小さいため、伝熱板１単独で冷却対象物を十分に冷却するためには伝熱板１を相当の重量とする必要がある。 Since the thermal conductivity of the metal that is the material of the heat transfer plate 1 is generally high, the heat of the object to be cooled efficiently transfers to the heat transfer plate 1. However, since metal has a smaller specific heat capacity than water, it is necessary to make the heat transfer plate 1 a considerable weight in order to sufficiently cool the object to be cooled by the heat transfer plate 1 alone.

このため、一般的に金属よりも比熱容量が大きい材質である蓄冷材３を、伝熱板１の外周囲に接触させることにより、伝熱板１の比熱容量を補う。伝熱板１は、蓄冷材３に接触する部分の表面積を大きくしているため、冷却対象物から取り込んだ熱を効率よく蓄冷材３へ移動させることができる。 Therefore, the specific heat capacity of the heat transfer plate 1 is supplemented by contacting the cold storage material 3, which is a material having a specific heat capacity larger than that of metal, with the outer periphery of the heat transfer plate 1. Since the heat transfer plate 1 has a large surface area of the portion in contact with the cold storage material 3, the heat taken in from the object to be cooled can be efficiently transferred to the cold storage material 3.

蓄冷材３を真水とした場合には、氷の融解温度未満すなわち氷点下の温度で冷却対象物を冷却できる熱量は氷の顕熱分のみであるが、蓄冷材３を塩水とすることで融解温度を氷点下にすることができるため、蓄冷材３を塩水とした場合には、氷点下の温度で冷却対象物を冷却できる熱量に氷の潜熱分が加わる。 When the cold storage material 3 is fresh water, the amount of heat that can cool the object to be cooled at a temperature below the freezing point, that is, below the melting temperature of ice, is only the apparent heat of the ice. When the cold storage material 3 is salt water, the latent heat of ice is added to the amount of heat that can cool the object to be cooled at the temperature below the freezing point.

本器の冷却能力は、伝熱板１の材質・形状・重量、蓄冷材３の材質・重量、などにより変化させることができる。 The cooling capacity of the instrument can be changed depending on the material, shape, and weight of the heat transfer plate 1, the material, weight, and the like of the cold storage material 3.

本器では、冷却対象物をそのまま本器に挿入する使用方法のほか、挿入孔２に挿入できるように製作した、各種用途に特化した各種アタッチメント５を利用する使用方法を選択することができる。 In this instrument, in addition to the usage method of inserting the object to be cooled into the instrument as it is, the usage method of using various attachments 5 specialized for various purposes, which are manufactured so as to be inserted into the insertion hole 2, can be selected. ..

図１に本発明の請求項１に係る急速冷却器の実施例を示す。図１において急速冷却器は、冷却対象物またはアタッチメント５を挿入する挿入孔２があり、挿入孔２以外の表面積は挿入孔２の表面積の１．５倍以上とした、金属製の伝熱板１と、伝熱板１の挿入孔２以外の表面を内包した蓄冷材充填用空間を提供するケース４と、この空間に充填した蓄冷材３、で構成する。 FIG. 1 shows an embodiment of the rapid cooler according to claim 1 of the present invention. In FIG. 1, the rapid cooler has an insertion hole 2 into which an object to be cooled or an attachment 5 is inserted, and the surface area other than the insertion hole 2 is 1.5 times or more the surface area of the insertion hole 2. It is composed of 1 and a case 4 for providing a space for filling a cold storage material containing a surface other than the insertion hole 2 of the heat transfer plate 1, and a cold storage material 3 filled in this space.

請求項１に係る本器は、図２（ａ）～（ｅ）に示すアタッチメント５を挿入孔２に挿入することで様々な用途に特化した利用ができる。これらのアタッチメント５の主材質は、伝熱板１と同様に金属である。図２（ａ）は缶飲料用アタッチメントで、缶飲料を挿入する缶挿入孔があり、急速に缶飲料を冷却するために使用する。図２（ｂ）は製氷皿アタッチメントであり、急速に氷を製造するために使用する。図２（ｃ）は落とし蓋アタッチメントであり、冷却対象物の上面からも冷却するために使用する。特に、食品保存袋などに入れた液体状の冷却対象物の場合には、冷却対象物の上面に密着させることができるため効果的である。図２（ｄ）は汁物容器アタッチメントであり、カレーや汁物の粗熱取りや急速冷却に使用し、落とし蓋アタッチメントと併用することで、湯気による冷凍庫や冷凍室内への悪影響を低減できる。図２（ｅ）はアイスキャンディ製造用アタッチメントであり、アイスキャンディを製造するために使用する。これらのアタッチメント以外にも、弁当の粗熱を取りやすくするため、そのまま弁当箱として使用できるアタッチメントや、本器をワインクーラーとして使用するためのアタッチメントや、冷却効果を高めることを目的に缶飲料など円柱状の冷却対象物を自動回転させるためのアタッチメントなども考えられ、本器はアイデア次第で様々な用途に利用できる。 The instrument according to claim 1 can be used for various purposes by inserting the attachment 5 shown in FIGS. 2A to 2E into the insertion hole 2. The main material of these attachments 5 is metal like the heat transfer plate 1. FIG. 2A is an attachment for a canned beverage, which has a can insertion hole for inserting the canned beverage and is used for rapidly cooling the canned beverage. FIG. 2 (b) is an ice tray attachment, which is used to rapidly produce ice. FIG. 2C shows a drop lid attachment, which is used for cooling from the upper surface of the object to be cooled. In particular, in the case of a liquid cooling object placed in a food storage bag or the like, it is effective because it can be brought into close contact with the upper surface of the cooling object. FIG. 2D shows a soup container attachment, which is used for removing the rough heat of curry and soup and for rapid cooling, and when used in combination with the otoshi buta attachment, the adverse effect of steam on the freezer and the freezing room can be reduced. FIG. 2 (e) is an attachment for producing an ice lolly, which is used for producing an ice lolly. In addition to these attachments, attachments that can be used as a lunch box as they are to make it easier to remove the rough heat of the lunch box, attachments for using this device as a wine cooler, canned beverages for the purpose of enhancing the cooling effect, etc. An attachment for automatically rotating a columnar object to be cooled can be considered, and this instrument can be used for various purposes depending on the idea.

伝熱板１の材質は、熱伝導率が大きく、比較的安価な材質であるアルミや銅を想定するが、耐食性を重視したステンレスや、コスト度外視で大きい熱伝導率を求めた銀、などの他の材質を排除するものではない。 The material of the heat transfer plate 1 is assumed to be aluminum or copper, which has a high thermal conductivity and is a relatively inexpensive material, but stainless steel, which emphasizes corrosion resistance, and silver, which requires a large thermal conductivity without considering the cost, are used. It does not exclude other materials.

蓄冷材３の主材質は、蓄冷材として広く利用されており、氷の潜熱を利用できる材質である水を想定するが、グリコール類などの他の材質を排除するものではない。 The main material of the cold storage material 3 is widely used as a cold storage material, and water, which is a material that can utilize the latent heat of ice, is assumed, but other materials such as glycols are not excluded.

本器の使用には、本器全体が十分に冷却されている必要があるため、使用するときにだけ冷凍庫や冷凍室に入れるという使用方法は現実的ではない。このため、本器は冷凍庫や冷凍室内に常時設置することを前提としていることから、本器を冷凍庫や冷凍室に組み込むことは利便性向上に有効である。また、冷凍庫や冷凍室に組み込まれた本器を着脱できるようにすることで、不要時に取り外すことや、冷凍庫や冷凍室外で一時的に使用することができる。 Since the entire unit needs to be sufficiently cooled in order to use the unit, it is not realistic to put it in the freezer or freezer only when it is used. For this reason, since it is assumed that the instrument is always installed in the freezer or the freezer, it is effective to incorporate the instrument into the freezer or the freezer to improve convenience. In addition, by making it possible to attach and detach the instrument built into the freezer or freezer, it can be removed when it is not needed, or it can be used temporarily outside the freezer or freezer.

本器に冷却対象物を入れたままにすると冷却対象物が凍結する可能性が高いことから、本器にタイマー表示や警告音発生装置を組み込むことも利便性向上に有効である。 Since there is a high possibility that the object to be cooled will freeze if the object to be cooled is left in the instrument, it is also effective to incorporate a timer display and a warning sound generator into the instrument to improve convenience.

蓄冷材３の凝固膨張によるケース４破損の予防としては、ケース４を柔軟材料とすることや、ケース４の内側に非吸水性の発泡弾性材料を貼り付ける方法などが考えられ、後者では発泡弾性材料の断熱材としての効果も得られる。 To prevent damage to the case 4 due to solidification and expansion of the cold storage material 3, it is conceivable to use the case 4 as a flexible material or to attach a non-absorbent foam elastic material to the inside of the case 4, and the latter has foam elasticity. The effect of the material as a heat insulating material can also be obtained.

蓄冷材３の成分によっては、蓄冷材３に高吸水性ポリマーを配合してゲル状にすることにより、蓄冷材３の漏れ出しを予防することができる。 Depending on the components of the cold storage material 3, the leakage of the cold storage material 3 can be prevented by blending the superabsorbent polymer with the cold storage material 3 to form a gel.
