〔産業上の利用分野〕
本発明は、自動車の電源に接続することにより、走行中

置に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention stores cold air while the vehicle is running by connecting it to the power source of the vehicle, and even after the vehicle reaches its destination and the power is turned off. This invention relates to a refrigerator that keeps items inside the refrigerator cool for a long time, and an electronic cooling device used therein.
自動車の電源を利用した車載型の冷蔵庫は、売店や自動
販売機等が配置されていない郊外の行楽地やキャンプ場
等に出かける場合、飲物等を保冷したままで携行しうる
利点があり、しかも走行中の車内で気軽に利用すること
ができるため、近年普及しつつある。An on-vehicle refrigerator that uses the car's power supply has the advantage of being able to keep drinks and other items cold when you go to suburban resorts or campgrounds where there are no shops or vending machines. It has become popular in recent years because it can be easily used inside a moving car.
従来の車載用冷蔵庫は、通常の家庭用冷蔵庫と同様に、
冷媒を使用した熱交換器を備えるものが殆んどである。Traditional car refrigerators, like regular household refrigerators,
Most are equipped with a heat exchanger that uses refrigerant.
上述の冷蔵庫は、電圧を高めるためのコンバータ、コン
プレッサ、および熱交換器等の比較的大型となり易い付
属機器を備えているため、その小型化および軽量化には
限界がある。Since the above-mentioned refrigerator is equipped with accessory devices that tend to be relatively large, such as a converter for increasing the voltage, a compressor, and a heat exchanger, there is a limit to how the refrigerator can be made smaller and lighter.
また、この種の車載用冷蔵庫は、消費電力が多いため、
バッテリ電圧に余裕のある走行中のみに使用し、エンジ
ンの停止時には、電源をＯＦＦとして、バッテリ負荷を
軽減しうるようにしである。In addition, this type of in-vehicle refrigerator consumes a lot of power, so
It is designed to be used only while driving when there is sufficient battery voltage, and when the engine is stopped, the power is turned off to reduce the load on the battery.
そのため、目的地へ到着して電源を切り、庫内の物を出
し入れすると、庫内温度は徐々に常温に近づき、せっか
くそれまで保冷してきた内容物の温度を、比較的短時間
の間に上昇させる結果となる。Therefore, when you arrive at your destination, turn off the power, and take things out of the refrigerator, the temperature inside the refrigerator gradually approaches room temperature, and the temperature of the contents that have been kept cold rises in a relatively short period of time. This results in
本発明は、上記問題点を解決するためになされたもので
、小型化および軽量化が図れ、電源をＯＦＦとした後で
も、引き続き庫内温度を、走行中に蓄積された吸熱エネ
ルギーを利用して、低温に保ち、しかも、庫内の物を長
時間にわたり保冷しうるようにした車載用冷蔵庫、およ
びそれに使用される電子冷却装置を提供することを目的
としている。The present invention was made to solve the above-mentioned problems, and it is possible to reduce the size and weight, and even after the power is turned off, the temperature inside the refrigerator can be maintained by using the endothermic energy accumulated during driving. It is an object of the present invention to provide an on-vehicle refrigerator that can maintain a low temperature and keep things inside cold for a long time, and an electronic cooling device used therein.
上記目的を達成するために、本発明の車載用冷蔵庫は、
開閉自在の扉体を有する断熱性の庫体と、前記庫体の一
壁面に設けられた電子冷却素子と、前記庫体の内側に配
設されるとともに、前記電子冷却素子における吸熱部側
に密着された蓄冷体とを備えてなるものである。In order to achieve the above object, the in-vehicle refrigerator of the present invention has the following features:
an insulating storage body having a door body that can be opened and closed; an electronic cooling element provided on one wall of the storage body; It is equipped with a cold storage body that is in close contact with the cold storage body.
また、これに使用される電子冷却装置は、電子冷却素子
を、その発熱部側に設けた放熱板と、吸熱部側に設けた
吸熱板とにより、密着状として、かつ互いの熱伝導を遮
断して挾持するとともに、前記吸熱板側に、蓄冷材を設
けたことを特徴としている。In addition, the electronic cooling device used for this uses a heat dissipating plate provided on the heat generating part side of the electronic cooling element and a heat absorbing plate provided on the heat absorbing part side, which keep the electronic cooling element in close contact with each other and block heat conduction from each other. It is characterized in that a cold storage material is provided on the side of the heat absorption plate.
本発明によると、電子冷却素子の吸熱作用により、蓄冷
材が凝固させられる。According to the present invention, the cold storage material is solidified by the heat absorption action of the electronic cooling element.
電源を切ると、凝固した蓄冷材は、徐々に相変化を起こ
して融解し始めるが、このとき、周囲より融解熱を奪う
ため、蓄冷材が完全に融解する間、引き続き庫内の温度
上昇を抑制しうる。When the power is turned off, the solidified cold storage material gradually undergoes a phase change and begins to melt, but at this time, it absorbs the heat of fusion from the surroundings, so the temperature inside the refrigerator continues to rise while the cold storage material completely melts. Can be suppressed.
従って、庫内に入れた缶ジュース等を、長時間にわたり
保冷することができる。Therefore, canned juice etc. placed in the refrigerator can be kept cold for a long time.

吸熱板（８）、および吸熱板（８）に載置された蓄冷体
（９）の温度は徐々に低下する。As a result, the cooling fan (5) is activated, and at the same time, electricity is started to be applied to each cooling element (7).
) begins to absorb heat, and the temperature of the heat absorption plate (8) that is in close contact with this and the cool storage body (9) placed on the heat absorption plate (8) gradually decreases.

4) and (15) below, the cold storage material (14) gradually undergoes a phase change and freezes, and then the cold storage material (15), which has a lower melting point, undergoes a phase change and solidifies.
このとき、両蓄冷材（１４） （１５）には、相変化に
伴う潜熱が蓄えられる。At this time, latent heat accompanying the phase change is stored in both the cold storage materials (14) and (15).
なお、蓄冷材（１５）は、先に固化した蓄冷材（１４）
を熱伝漂媒体として、効果的に熱吸収される。Note that the cold storage material (15) is the cold storage material (14) that has been solidified first.
As a heat transfer medium, heat can be effectively absorbed.
これにより、庫内の温度は、缶ジュース（Ｄ）等を冷却
又は保冷するに充分な温度まで下がり、自動車の走行中
、すなわち電源を入れている間は。As a result, the temperature inside the refrigerator falls to a temperature sufficient to cool or keep the canned juice (D) etc. while the car is running, that is, while the power is turned on.
この状態が保たれる。This state is maintained.

融解し始め、その温度が、蓄冷材（１４）の融解点、す
なわち氷の融解点である０℃を越えたとき、蓄冷材（１
４）が徐々に融解し始める。Thus, when the car arrives at its destination and turns off the power, the cold storage material (15), which has a lower melting point, begins to melt gradually, and its temperature reaches the melting point of the cold storage material (14), i.e. When the temperature exceeds 0℃, which is the melting point of ice, the cold storage material (1
4) begins to gradually melt.
従って、例えば蓄冷材（１５）の融解点を一５℃に設定
すれば、これが完全に融解する間、すなわち蓄冷材（１
４）が融解し始めるまでの間は、庫内の温度は、少なく

ジュース（Ｄ）等を長く保冷しうるようになる。Therefore, for example, if the melting point of the regenerator material (15) is set to -5°C, the melting point of the regenerator material (15) is set at -5°C.
4), the temperature inside the refrigerator is maintained at least below 0° C., which is the melting point of the cold storage material (14). Moreover, the time required for the cold storage material (15) to melt and reach the melting point of the cold storage material (14) plus the time required for complete melting of the cold storage material (14) is the time required for the cold storage material (15) to absorb heat of fusion from the surroundings. The temperature inside can be kept low for a long time, and canned juice (D) etc. can be kept cold for a long time.
なお、蓄冷体（９）を、上述のように２相とせずに、水
又はポリエチレングリコール等の蓄冷材を単体で使用す

ファン（２５）を作動して冷却するようにしてもよい。In this case, in consideration of the case where sufficient wind is not obtained due to traffic jams, etc., the temperature of the heat sink (21) or the wind speed is sensed, and the power supply to the cooling element (7) is stopped or the cooling fan is turned off. (25) may be operated for cooling.
以上のように、上記実施例の冷蔵庫および電子冷却装置
においては、コンプレッサや熱交換器等の大きな機器を
用いていないため、構造が簡単であり、かつ小型軽量と
しうる利点がある。As described above, the refrigerator and electronic cooling device of the above embodiments do not use large equipment such as a compressor or a heat exchanger, so they have the advantage of being simple in structure and being small and lightweight.
また、電子冷却装置（２）及び（２０）がユニット化さ
れているため、断熱性の庫体（３）（２４）の形状の選
択が自由であり、自動車の車種に合せた空間に適する形
状、又は使用者が自由にデザインした形状等としうる。In addition, since the electronic cooling devices (2) and (20) are unitized, the shape of the heat-insulating storage body (3) and (24) can be freely selected, and the shape is suitable for the space according to the type of car. , or a shape freely designed by the user.
本発明によれば、電源をＯＦＦとした後でも、蓄冷材の
融解している間は、引き続き庫内の温度は低温のまま維
持されるため、保冷効果が高く、庫内の物を長時間にわ
たり保冷しうる。According to the present invention, even after the power is turned off, the temperature inside the refrigerator is maintained at a low temperature while the cold storage material is melting, so the cold retention effect is high and the items inside the refrigerator can be kept for a long time. Can be kept cold for a long time.
なお、融解点の異なる蓄冷材を用いると、保冷時間をさ
らに延ばすことができる。Note that by using cold storage materials with different melting points, the cold storage time can be further extended.
