Description

本発明は貯蔵庫に関するものであり、特に、電気的な温度調節ユニットによって内部を保温及び／又は冷却することができる携帯用の貯蔵庫に関するものである。   The present invention relates to a storage, and more particularly, to a portable storage that can keep the inside warm and / or cool by an electrical temperature control unit.

従来、この種の貯蔵庫としては、例えば、内容器が設けられた本体（本発明の断熱箱体に該当する）と、蓋体（本発明の断熱箱体に該当する）と、前記本体内に設けられたスターリング冷凍機（本発明の温度調節ユニットに該当する）と、前記内容器内の温度を検出する温度センサとを有するものが知られている。そして、前記温度センサによって検出された温度に基づいて、前記スターリング冷凍機を制御することで、前記本体内に設けられた内容器の内部が、所望の温度に冷却される。なお、このような貯蔵庫では、前記温度センサは、前記内容器の内壁に伝熱的に貼り付けられているものが一般的である(例えば、特許文献１参照。)。
特開２００１−２２１５５３号公報 Conventionally, as this type of storage, for example, a main body (corresponding to the heat insulation box of the present invention) provided with an inner container, a lid (corresponding to the heat insulation box of the present invention), and the main body One having a Stirling refrigerator (corresponding to the temperature control unit of the present invention) provided and a temperature sensor for detecting the temperature in the inner container is known. And the inside of the inner container provided in the said main body is cooled to desired temperature by controlling the said Stirling refrigerator based on the temperature detected by the said temperature sensor.

JP 2001-221553 A

ところで、前述したような貯蔵庫としては、温度調節ユニットによって、内容器内に露出した熱交換器を冷却又は加熱し、この熱交換器と前記内容器内の空気との間で熱交換を行うことで、前記内容器内を冷却又は加熱するものと、温度調節ユニットによって内容器を冷却又は加熱し、この内容器自体を熱交換器として用い、内容器内の空気との間で熱交換を行うことで、前記内容器内を冷却又は加熱するものがある。そして、後者のような貯蔵庫では、前述したように、前記内容器自体が前記温度調節ユニットによって加熱又は冷却されるので、前記内容器自体の温度と前記内容器内の温度との間に隔たりが生じてしまい、前記内容器内を所望の温度に調節し難いという問題があった。そして、このような問題を避けるために、前記温度センサを前記内容器から離間して設けることも考えられるが、このように構成した場合、前記内容器内で前記温度センサが内容物に当接する等、前記温度センサが邪魔になってしまう虞があった。   By the way, as the storage as described above, the heat exchanger exposed in the inner container is cooled or heated by the temperature control unit, and heat exchange is performed between the heat exchanger and the air in the inner container. Then, the inner container is cooled or heated by the temperature control unit and the inner container is cooled or heated, and the inner container itself is used as a heat exchanger to exchange heat with the air in the inner container. Thus, there are some which cool or heat the inside of the inner container. In the latter storage, as described above, since the inner container itself is heated or cooled by the temperature control unit, there is a gap between the temperature of the inner container itself and the temperature in the inner container. There arises a problem that it is difficult to adjust the inside of the inner container to a desired temperature. In order to avoid such a problem, it may be possible to provide the temperature sensor apart from the inner container. However, in this case, the temperature sensor contacts the contents in the inner container. For example, the temperature sensor may get in the way.

It is.

本発明の請求項１に記載の貯蔵庫は、以上のように構成することにより、前記温度調節ユニットからの熱が前記内容器から前記温度センサに伝わらず、前記内容器内の空気の温度が前記温度センサに伝わることで、前記内容器内の空気、ひいては内容器の内容物の温度をほぼ正確に検出でき、この検出された温度に基づいて前記温度調節ユニットが制御されることで、前記内容器内の空気、ひいては内容物を、ほぼ正確に所望の温度に調節することができる。   The storage according to claim 1 of the present invention is configured as described above, so that heat from the temperature adjustment unit is not transferred from the inner container to the temperature sensor, and the temperature of the air in the inner container is By being transmitted to the temperature sensor, the temperature of the air in the inner container, and hence the contents of the inner container, can be detected almost accurately, and the temperature adjusting unit is controlled based on the detected temperature, whereby the contents are The air in the vessel, and thus the contents, can be adjusted to the desired temperature almost accurately.

Since it is wired, the length of the cord becomes long, and thereby, the influence of heat that reaches the temperature sensor by conducting the cord from the outside of the storage can be reduced.

以下、本発明の一実施形態について添付図面を参照して説明する。なお、本実施形態では、携帯用冷蔵庫について説明するが、これに限定されず、保温用の貯蔵庫であってもよく、また設置型の貯蔵庫であってもよい。   Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In addition, although this embodiment demonstrates a portable refrigerator, it is not limited to this, The storage for heat retention may be sufficient, and an installation type storage may be sufficient.

１は本実施形態の冷蔵庫であり、当該冷蔵庫１は、開口部２を有する略直方体状の本体３と、その開口部２を開閉するように本体３に取り付けられた蓋体４とからなる断熱箱体５により構成されている。   1 is a refrigerator according to the present embodiment, and the refrigerator 1 is a heat insulating unit including a substantially rectangular parallelepiped body 3 having an opening 2 and a lid 4 attached to the body 3 so as to open and close the opening 2. A box 5 is used.

本体３は、冷却又は保冷する対象物を収納することのできる、上部が開口した内容器６と、その内容器６を所定の空間を空けて取り囲む外容器７とを備え、その空間内の内容器６の周りは断熱材３Ａで充填されている。なお、外容器７は、断熱性を有し、成型が容易で、且つ軽量である等の理由より合成樹脂製である。ただし、これに限定されず、他の材料から形成されるものであってもよい。   The main body 3 is provided with an inner container 6 having an open upper portion and an outer container 7 that surrounds the inner container 6 with a predetermined space and can store an object to be cooled or kept, and the contents in the space. The space around the vessel 6 is filled with a heat insulating material 3A. The outer container 7 is made of a synthetic resin for reasons such as heat insulation, easy molding, and light weight. However, it is not limited to this and may be formed from other materials.

内容器６は、図２〜図４に示すように、縁部が上方に延びた矩形の底部８と、１枚の平板を折り曲げて底部８を囲むように形成された側部９とを備える。また、折り曲げた平板の端部間には隙間が設けられ、内容器６の内外を貫通する貫通部10が形成されている。その貫通部10には、取付体11が嵌め込まれ、その取付体11の内容器６外方側には温度センサ12が取り付けられている。なお、底部８は、成形が容易で且つ軽量な合成樹脂により形成されていると共に、側部９は熱伝導率が高く、軽量で且つ腐食しにくいアルミニウムにより形成されているが、これに限定されず、熱伝導率が高ければ他の材料から形成されてもよく、また、前記底部８も熱伝導性率の高い材質で形成してもよい。更に、アルミ板をプレスすること等により、底部８と側部９とを一体に形成してもよい。   As shown in FIGS. 2 to 4, the inner container 6 includes a rectangular bottom portion 8 whose edge portion extends upward, and a side portion 9 that is formed so as to surround a bottom portion 8 by bending one flat plate. . Further, a gap is provided between the end portions of the bent flat plate, and a through portion 10 penetrating the inside and outside of the inner container 6 is formed. An attachment body 11 is fitted into the penetrating portion 10, and a temperature sensor 12 is attached to the outer side of the inner container 6 of the attachment body 11. The bottom portion 8 is formed of a synthetic resin that is easy to mold and lightweight, and the side portion 9 is formed of aluminum that has high thermal conductivity, is lightweight, and is not easily corroded, but is limited thereto. If the thermal conductivity is high, it may be formed from other materials, and the bottom 8 may also be formed from a material having high thermal conductivity. Further, the bottom portion 8 and the side portion 9 may be integrally formed by pressing an aluminum plate or the like.

前記蓋体４は、内部が断熱材４Ａで充填された矩形部材であり、ヒンジ（図示せず）により前記本体３に回動自在に連結され、回動することによって前記開口部２を開閉するようになっている。また、前記蓋体４自体も、断熱性を有し、成型が容易で、且つ軽量である等の理由より合成樹脂製であるが、これに限定されず、熱伝導率の低いものであれば他の材質で形成されたものであってもよい。   The lid 4 is a rectangular member filled with a heat insulating material 4A. The lid 4 is rotatably connected to the main body 3 by a hinge (not shown) and opens and closes the opening 2 by rotating. It is like that. The lid 4 itself is also made of a synthetic resin for reasons such as heat insulation, easy molding, and light weight, but is not limited to this and has a low thermal conductivity. It may be formed of other materials.

また、上述の内容器６と前記外容器７との間の空間には、スターリング冷凍機14及びこの冷却機14を冷却するためのファン15などを備える温度調整ユニット16が取り付けられている。そして、前記スターリング冷凍機14には、冷媒（図示せず）を凝縮させる凝縮器17が熱的に接続されており、更にこの凝縮器17には、前記冷媒を循環させるための配管18から成るサーモサイフォン19が接続されている。なお、前記配管18は銅等の熱伝導率の高い材料で形成され、内容器６の側面を取り巻くように配置されている。そして、前記凝縮器17内において熱を奪われて凝縮した冷媒が前記配管18内を流れ、前記内容器６から熱を奪って蒸発し、この蒸発した冷媒が前記配管18を通って前記凝縮器17に至り、再び熱を奪われて凝縮する。これが繰り返されることによって、前記内容器６は冷却されることになる。   In addition, a temperature adjustment unit 16 including a Stirling refrigerator 14 and a fan 15 for cooling the cooler 14 is attached to the space between the inner container 6 and the outer container 7 described above. A condenser 17 for condensing a refrigerant (not shown) is thermally connected to the Stirling refrigerator 14, and the condenser 17 further includes a pipe 18 for circulating the refrigerant. A thermosiphon 19 is connected. The pipe 18 is made of a material having high thermal conductivity such as copper, and is disposed so as to surround the side surface of the inner container 6. Then, the refrigerant deprived of heat in the condenser 17 flows in the pipe 18 and evaporates by taking heat from the inner vessel 6, and the evaporated refrigerant passes through the pipe 18 to the condenser. It reaches 17 and is again deprived of heat and condensed. By repeating this, the inner container 6 is cooled.

前記外容器７の一側面には、使用者が外部より温度設定等の操作ができる押しボタン式操作部21と、この操作部21から入力された信号によって内部の前記温度調整ユニット16を制御する制御部22とが備えられている。なお、前記操作部21の操作形式は、押しボタン式に限定されず、例えばダイヤル式等であってもよい。   On one side of the outer container 7, a push button type operation unit 21 that allows a user to perform operation such as temperature setting from the outside, and the temperature adjustment unit 16 inside is controlled by a signal input from the operation unit 21. And a control unit 22. The operation form of the operation unit 21 is not limited to the push button type, and may be a dial type, for example.

次に、前記取付体11について詳述する。上述した、前記内容器６の貫通部10に取り付けられた前記取付体11は、長端部に溝23が形成された合成樹脂製の細長棒状部材であり、断面が略「エ」の字型をしている。図５は図３のＶ−Ｖ線に沿った前記取付体11の断面図である。図示のように、前記取付体11の長手方向中央部の前記内容器６外方側には、当該取付体11と一体形成された箱状のセンサ受容部25が設けられている。そのセンサ受容部25は、半円状に切り込まれた２枚の壁板24を内部に備え、その切り込み箇所には温度センサ12が嵌め込まれている。更に、前記センサ受容部25の内部は、その開口が図示しない粘着シート等で塞がれた空間となっている。また、前記取付体11の上端近傍の、同じく前記内容器６の外方側には、断面コの字型のコード固定部27が前記取付体11から突出して一体形成されており、前記温度センサ12から延びる電力供給及び温度計測信号送信のためのコード26が固定されている。そして、このコード26は、前記センサ受容部25から前記取付体11に沿って上方に延び、更に前記コード固定部27に沿って固定されることで、配線経路が長く形成されると共に、前記コード26が前記コード固定部27で固定されることで、前記断熱材３Ａを充填した際に前記コードが押し流されることが防がれている。また、前記取付体11の前記センサ受容部25が形成されている部分の前記内容器６の内方側には、図４及び図５に示すように、前記内容器６の内外を連通する連通路たる楕円形の連通孔28が３つ設けられている。なお、前記連通孔28の数は３つに限定されず、それ以上又はそれ以下であってもよく、また、前記連通孔28の形状も楕円形に限定されるものではなく、円形又は矩形等であってもよい。また、前記取付体11の材質は合成樹脂に限定されず、熱伝導率が低ければ他の材質であってもよい。   Next, the attachment body 11 will be described in detail. The attachment body 11 attached to the penetrating portion 10 of the inner container 6 described above is an elongated rod-shaped member made of a synthetic resin having a groove 23 formed at the long end, and has a substantially “e” -shaped cross section. I am doing. FIG. 5 is a cross-sectional view of the mounting body 11 taken along the line VV in FIG. As shown in the figure, a box-shaped sensor receiving portion 25 formed integrally with the mounting body 11 is provided on the outer side of the inner container 6 at the center in the longitudinal direction of the mounting body 11. The sensor receiving portion 25 includes two wall plates 24 cut in a semicircular shape, and the temperature sensor 12 is fitted in the cut portion. Further, the inside of the sensor receiving portion 25 is a space in which the opening is closed by an adhesive sheet (not shown). In addition, a cord fixing portion 27 having a U-shaped cross section is formed integrally with the temperature sensor in the vicinity of the upper end of the mounting body 11 and on the outer side of the inner container 6 so as to protrude from the mounting body 11. A cord 26 for power supply and temperature measurement signal transmission extending from 12 is fixed. The cord 26 extends upward from the sensor receiving portion 25 along the attachment body 11, and is further fixed along the cord fixing portion 27, so that a wiring path is formed long and the cord 26 Since 26 is fixed by the cord fixing portion 27, the cord is prevented from being washed away when the heat insulating material 3A is filled. Further, as shown in FIG. 4 and FIG. 5, a communication that communicates the inside and the outside of the inner container 6 is provided on the inner side of the inner container 6 of the portion of the mounting body 11 where the sensor receiving portion 25 is formed. Three oval communication holes 28 serving as passages are provided. The number of the communication holes 28 is not limited to three, but may be more or less, and the shape of the communication holes 28 is not limited to an ellipse, and may be circular or rectangular. It may be. Further, the material of the attachment body 11 is not limited to a synthetic resin, and other materials may be used as long as the thermal conductivity is low.

次に作用について説明する。使用者が、前記操作部21に設けられた前記冷蔵庫１の電源スイッチを入れると、前記スターリング冷凍機14が駆動されて前記凝縮器17が冷却され、この凝縮器17内で前記冷媒が凝縮すると共に、前記凝縮器17に接続された配管18内を凝縮した冷媒が流れる。そして、凝縮した冷媒は、前記内容器６の外周に沿って設けられた前記配管18を流れる。このとき、前記内容器６及び配管18は、共に熱伝導率の高い材質で形成されているため、前記内容器６の熱が前記配管18を経て前記冷媒に移動する。そして、熱を奪われた前記内容器６が冷却源となることで、前記内容器６の内部が冷却される。そして、前記内容器６内部からの熱を吸収すると、前記配管18内の冷媒が蒸発し、前記配管18を通って前記凝縮器17に戻る。   Next, the operation will be described. When a user turns on the power switch of the refrigerator 1 provided in the operation unit 21, the Stirling refrigerator 14 is driven to cool the condenser 17, and the refrigerant condenses in the condenser 17. At the same time, the condensed refrigerant flows in the pipe 18 connected to the condenser 17. The condensed refrigerant flows through the pipe 18 provided along the outer periphery of the inner container 6. At this time, since the inner container 6 and the pipe 18 are both made of a material having high thermal conductivity, the heat of the inner container 6 moves to the refrigerant through the pipe 18. And the inside of the said inner container 6 is cooled because the said inner container 6 from which heat was taken becomes a cooling source. When the heat from the inside of the inner container 6 is absorbed, the refrigerant in the pipe 18 evaporates and returns to the condenser 17 through the pipe 18.

このとき、前記内容器６内部の冷却された空気は、前記連通孔28を通して前記内容器６の外部に備えられた前記温度センサ12に到達し、これによって、前記内容器６内部の温度が測定される。そして、その測定値は、電気信号として前記制御部22に送られ、この制御部22で予め設定された設定温度と比較され、設定温度よりも高い場合は、前記スターリング冷凍機14への印加電力が増加されて凝縮速度が速められて、前記内容器６内部の冷却が促進される。また、設定温度よりも低い場合は、前記スターリング冷凍機14への印加電力が低下されて、前記内容器６内部の冷却が抑制され、前記内容器６内部の温度が所望の温度に保たれる。   At this time, the cooled air inside the inner container 6 reaches the temperature sensor 12 provided outside the inner container 6 through the communication hole 28, whereby the temperature inside the inner container 6 is measured. Is done. Then, the measured value is sent as an electrical signal to the control unit 22 and compared with a preset temperature set in advance by the control unit 22. If the measured value is higher than the preset temperature, the applied power to the Stirling refrigerator 14 is Is increased and the condensation rate is increased, and the cooling of the inner container 6 is promoted. When the temperature is lower than the set temperature, the power applied to the Stirling refrigerator 14 is reduced, the cooling inside the inner container 6 is suppressed, and the temperature inside the inner container 6 is maintained at a desired temperature. .

そして、本実施形態によると、前記温度センサ12は、熱伝導率の低い材質からなる前記取付体11に取り付けられているため、冷却源である前記内容器６と温度センサ12とが熱的に直接接触しておらず、前記内容器６内部の空気が前記温度センサ12に触れることで、前記冷媒の冷熱が前記配管18及び内容器６を経て前記温度センサ12に殆ど伝導せず、前記内容器６内の空気の温度が前記温度センサ12に伝わるようになっている。したがって、前記温度センサ12によって、前記内容器６内部の空気の温度をほぼ正確に検出でき、この検出された温度に基づいて前記温度調節ユニット16が制御され、前記内容器６内の空気、ひいては内容物を、ほぼ正確に所望の温度に調節することができる。   According to this embodiment, since the temperature sensor 12 is attached to the attachment body 11 made of a material having low thermal conductivity, the inner container 6 that is a cooling source and the temperature sensor 12 are thermally connected. When the air inside the inner container 6 is not in direct contact with the temperature sensor 12, the cold heat of the refrigerant is hardly conducted to the temperature sensor 12 through the pipe 18 and the inner container 6, The temperature of the air in the vessel 6 is transmitted to the temperature sensor 12. Therefore, the temperature of the air inside the inner container 6 can be detected almost accurately by the temperature sensor 12, and the temperature adjusting unit 16 is controlled based on the detected temperature, and the air in the inner container 6 and consequently The contents can be adjusted to the desired temperature almost exactly.

また、本実施形態の貯蔵庫は、前記温度センサ12が前記内容器６内に露出せず、前記内容器６に対して殆ど段差が形成されないように取り付けられている。したがって、前記温度センサ12が、被冷却物の格納の際に邪魔になることがない。   In addition, the storage of this embodiment is attached so that the temperature sensor 12 is not exposed in the inner container 6 and almost no step is formed with respect to the inner container 6. Therefore, the temperature sensor 12 does not get in the way of storing the object to be cooled.

また、本実施形態の貯蔵庫の前記内容器６は、板材を折り曲げて構成し、両端の隙間に前記貫通部10を形成しているため、安価に前記内容器６を形成することができ、また容易に前記貫通部10を設けることができる。   In addition, the inner container 6 of the storage of the present embodiment is configured by bending a plate material, and the through portion 10 is formed in the gap between both ends, so that the inner container 6 can be formed at a low cost. The through portion 10 can be easily provided.

更に、本発明の貯蔵庫の前記取付体11は、その上部の外方側に突出して前記コード固定部27が形成されているため、前記温度センサ12のコード26を前記取付体11に沿って上方に延ばし、更に前記前記コード固定部27に沿って前記内容器６から離れる方向に延ばすことで、配線される前記温度センサ12のコード26の長さを長くした状態で固定することができ、これによって、貯蔵庫の外部からコード26を伝導して温度センサ12に至る熱の影響を減じ、前記内容器６内の空気、ひいては内容物を、より正確に所望の温度に調節することができる。   Furthermore, since the attachment body 11 of the storage of the present invention protrudes outward on the upper side and the cord fixing portion 27 is formed, the cord 26 of the temperature sensor 12 is moved upward along the attachment body 11. And the cord 26 of the temperature sensor 12 to be wired can be fixed in a lengthened state by extending in the direction away from the inner container 6 along the cord fixing portion 27. Thus, the influence of the heat reaching the temperature sensor 12 through the cord 26 from the outside of the storage can be reduced, and the air in the inner container 6, and thus the contents, can be adjusted to a desired temperature more accurately.
