Description

【0001】
【発明の属する技術分野】
本発明は、例えば冷凍または冷蔵の食品や飲料等を車両で運搬するための保冷庫に関するものである。
【0002】
【従来の技術】
従来、食品や飲料等の物品の運搬、例えば牛乳の配達においては、小売店の商品を小型トラックに積載して配達先まで運搬しているが、最近では品質の維持等を目的として商品の温度管理が必要とされている。そこで、小型トラック等の車両の荷台に搭載した保冷庫に商品を収容し、小売店から配達先まで商品を保冷した状態で運搬するようにしている。また、このような目的で使用される車載用保冷庫としては、例えば特開平2−106677号公報に記載されているように、断熱性の保冷庫本体の前面に開閉扉を有し、保冷庫本体に付設された冷凍装置によって庫内を冷却するようにしたものが知られている。また、車載用保冷庫の他の例として、保冷庫本体の前面上部を開閉する上部開閉扉を備え、上部開閉扉を車両の荷台の側壁よりも上方に配置することにより、上部開閉扉の開閉のみによって物品の出し入れを行えるようにしたものが本出願人から提案されている(特願平10−271074号)。
【0003】
【発明が解決しようとする課題】
ところで、前記保冷庫では、例えば小売店等において、車両の荷台の側壁を開放し、上部開閉扉及び下部開閉扉の両方を開放して商品の収納を行った後、配達先では上部開閉扉のみを開閉して商品を取出すといった使用形態が多い。即ち、下部開閉扉よりも上部開閉扉の方が頻繁に開閉される。しかしながら、前記保冷庫では、保冷庫本体内に設けた温度検出器の検出温度に基づいて冷凍装置の制御等を行っているため、上部開閉扉の頻繁な開閉により、温度検出器の検出温度が外気の侵入による影響を受け易いという課題が残されていた。
【0004】
本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、上部開閉部材が頻繁に開閉される場合でも、外気の侵入による温度検出器への影響を少なくすることのできる保冷庫を提供することにある。
【0005】
【課題を解決するための手段】
本発明は前記目的を達成するために、請求項1では、前面を開口した保冷庫本体と、保冷庫本体の前面開口部の上部を開閉する上部開閉部材と、保冷庫本体の前面開口部の下部を開閉する下部開閉部材と、保冷庫本体の内面に設けられ、庫内の温度を検出する温度検出器とを備え、車両の荷台に搭載して使用される保冷庫において、前記温度検出器を上部開閉部材よりも下方に配置し、上部開閉部材を車両の荷台の側壁よりも上方に位置するように設けている。これにより、保冷庫本体内の温度検出器が上部開閉部材よりも下方に配置されていることから、上部開閉部材のみを開放した状態では外部から侵入する空気が温度検出器まで容易に到達することはない。また、保冷庫の上部開閉部材は車両の側壁よりも上方に位置することから、保冷庫本体の前面側を車両の側壁に近接させた状態で上部開閉部材のみを開閉することができる。
【0006】
また、請求項2では、請求項1記載の保冷庫において、前記温度検出器を保冷庫本体内の背面寄りに配置している。これにより、温度検出器が保冷庫本体内の背面寄りに配置されていることから、請求項1の作用を達成するためにより有利である。
【0007】
【発明の実施の形態】
図1乃至図6は本発明の一実施形態を示すもので、図1は車載用保冷庫の全体斜視図、図2は上部開閉扉を開放した状態を示す車載用保冷庫の全体斜視図、図3は車載用保冷庫の正面断面図、図4は図3のA−A線矢視方向断面図、図5はセンサユニットの分解斜視図、図6は車両への搭載状態を示す側面図である。
【0008】
この車載用保冷庫は、前面を開口した保冷庫本体1と、保冷庫本体1の前面上部を開閉する上部開閉扉2と、保冷庫本体1の前面下部を開閉する下部開閉扉3とから構成されている。
【0009】
保冷庫本体1は内部に断熱壁によって囲まれた物品収納部1aを有し、その一側面側には機械室1bが設けられ、機械室1b内には物品収納部1a内を冷却するための冷凍機器(図示せず)が収容されている。また、保冷庫本体1の前面には、庫内温度を表示する温度表示部1cが設けられている。
【0010】
上部開閉扉2は断熱性の部材によって形成され、その幅方向一端側を複数の蝶番2aによって保冷庫本体1に連結されている。この場合、上部開閉扉2は、図6に示すように保冷庫本体1の下端から高さHよりも上方、即ち車両10の荷台11の側壁12よりも上方に形成されている。また、上部開閉扉2の幅方向他端側には周知構造のロック部材2bが取付けられ、ロック部材2bは所定の操作により上部開閉扉2を保冷庫本体1側にロック及びロック解除するようになっている。
【0011】
下部開閉扉3は断熱性の部材によって形成され、その幅方向一端側を複数の蝶番3aによって保冷庫本体1に連結されている。また、下部開閉扉3の幅方向他端側には前述と同等のロック部材3bが取付けられている。
【0012】
また、保冷庫本体1の物品収納部1a内には庫内温度検出用のセンサユニット4が取付けられ、センサユニット4は、庫内温度制御用の第1の温度センサ4aと、庫内温度表示用の第2の温度センサ4bと、各温度センサ4a,4bが取付けられる取付板4cとからなる。第1の温度センサ4aは冷凍機器の制御部(図示せず)に接続され、その検出温度に基づいて冷凍機器の圧縮機(図示せず)が制御されるようになっている。第2の温度センサ4bは保冷庫本体1の温度表示部1cに接続され、その検出温度に基づいて庫内の温度が表示されるようになっている。取付板4cは多数の通気孔4dを有し、各温度センサ4a,4bを覆うように板状に形成されている。このセンサユニット4は保冷庫本体1の内側面の背面寄りに取付けられ、上部開閉扉2よりも下方に配置されている。即ち、図6に示すようにセンサユニット4の上端の高さL1 は上部開閉扉2の下端の高さL2 よりも低く位置している。
【0013】
以上のように構成された車載用保冷庫は、図6に示すように小型トラックからなる車両10の荷台11に搭載され、図示しないロープやベルト等によって荷台11に固定される。この場合、保冷庫本体1は前面を車両11の後方に向けて配置され、保冷庫本体1内への商品の出し入れは荷台11の後方から上部開閉扉2を開閉することによって行われる。即ち、この車載用保冷庫では、例えば牛乳等の商品を保冷庫本体1内に収容し、商品を保冷庫本体1内で保冷した状態で小売店等から配達先まで運搬される。この場合、車両10の側壁12を開放し、各開閉扉2,3の両方を開放すれば、小売店等における商品の収納を容易に行うことができる。また、保冷庫の上部開閉扉2は車両10の後部側壁12よりも上方に形成されていることから、保冷庫本体1の前面側を車両10の後端に近接させた状態で上部開閉扉2のみを開閉することができ、配達先等における商品の取出しを容易に行うことができる。その際、保冷庫本体1内のセンサユニット4が上部開閉扉2よりも下方に配置され、且つ保冷庫本体1内の背面寄りに配置されていることから、上部開閉扉2のみを開放した状態では外部から侵入する空気がセンサユニット4まで容易に到達することはない。
【0014】
このように、本実施形態の車載用保冷庫によれば、保冷庫本体1内の温度を検出するセンサユニット4を上部開閉扉2よりも下方に配置したので、上部開閉扉2のみを開放した状態では外部から侵入する空気がセンサユニット4まで容易に到達することがなく、上部開閉扉2が頻繁に開閉される場合でも、外気の侵入によるセンサユニット4の各温度センサ4a,4bへの影響を極めて少なくすることができる。更に、センサユニット4を保冷庫本体1内の背面寄りに配置したので、侵入外気の影響をより少なくすることができる。
【0015】
尚、前記実施形態では車両10に搭載して運搬される車載用の保冷庫を示したが、移動を伴わずに任意の場所に設置される保冷庫にも本発明を適用することができる。
【0016】
【発明の効果】
以上説明したように、請求項1及び2の保冷庫によれば、上部開閉部材が頻繁に開閉される場合でも、外気の侵入による温度検出器への影響を極めて少なくすることができ、庫内温度の制御等に極めて有利である。また、保冷庫本体の前面側を車両の側壁に近接させた状態で上部開閉部材のみを開閉することができるので、配達先等における商品の取出しを容易に行うことができる。
