Description

本発明は、例えば検体、細胞、ＤＮＡ、血液、製剤、高級食料品等の各種保存物を超低温で保存するための超低温フリーザに関し、特に、開閉扉を開けた時の開口部付近に発生する氷の付着を最小限に抑えることができる超低温フリーザに関する。   The present invention relates to an ultra-low temperature freezer for storing various stored items such as specimens, cells, DNA, blood, pharmaceuticals, and high-quality food products at an ultra-low temperature, and in particular, ice generated near the opening when the door is opened. The present invention relates to an ultra-low temperature freezer that can minimize the adhesion of water.

一般に、バイオ分野、医療分野、食品分野等では、検体、細胞、ＤＮＡ、血液、製剤、高級食料品等の貴重な保存物を長期に亙って収納・保存するため、−３０℃〜−１５０℃に温度設定可能な冷凍室を有する超低温フリーザ（冷凍庫）が使用されている。   In general, in the bio field, the medical field, the food field, and the like, in order to store and store valuable preservation materials such as specimens, cells, DNA, blood, pharmaceuticals, and high-quality food products over a long period of time, −30 ° C. to −150 ° C. An ultra-low temperature freezer (freezer) having a freezing room whose temperature can be set to ° C. is used.

近年、環境保護によるフロン規制の影響で、フロン規制に対応した超低温フリーザが開発されている。しかし、この種の超低温フリーザでは、フロンの使用禁止によって冷却能力が低下するため、例えば保存物の取り出しの際に冷凍室内の温度が上昇し、コンプレッサの可動時間が長くなる。その結果、コンプレッサが故障しやすくなり、製品寿命が短くなるという問題があった。   In recent years, ultra-low temperature freezers that comply with CFC regulations have been developed under the influence of CFC regulations due to environmental protection. However, in this type of ultra-low temperature freezer, the cooling capacity is reduced due to the prohibition of the use of chlorofluorocarbon, so that, for example, the temperature in the freezer compartment rises when a stored item is taken out, and the operation time of the compressor becomes longer. As a result, there is a problem that the compressor is likely to break down and the product life is shortened.

そこで、冷凍室内の断熱効果を向上させるため、開閉扉及び筐体に断熱材を配置した超低温フリーザが提案されている（例えば特許文献１参照）。   Then, in order to improve the heat insulation effect in a freezer compartment, the ultra-low temperature freezer which has arrange | positioned the heat insulating material to the door and the housing | casing is proposed (for example, refer patent document 1).

特開２００２−３３３２５５号公報JP 2002-333255 A

従来の超低温フリーザでは、開閉扉及び筐体に断熱材を配置しているので、低温での温度維持を良好にすることができる。   In the conventional ultra-low temperature freezer, since the heat insulating material is arranged in the door and the casing, the temperature can be maintained well at a low temperature.

しかし、開閉扉を開けると、広い開口部が開放されるので、内外の温度差により冷凍室内の冷気が外部に大量に流出して、開口部付近の温度が上昇する。これによって開口部付近の空気が水滴となり、再度、開閉扉を閉めると、この水滴が氷となって開口部付近に付着する。このように開閉扉の開閉の度に氷の付着が蓄積されて、大きな氷の塊が形成される。その結果、開口部付近に形成された氷の塊のために開閉扉をスムーズに開閉できなくなったり、保存物を入れる貯蔵ケースをスムーズに出し入れできなくなったりするという課題があった。また、上記の氷の付着は、開口部付近の温度上昇をもたらし、コンプレッサに負荷がかかるという課題があった。   However, when the open / close door is opened, the wide opening is opened, so that a large amount of cool air in the freezer compartment flows out to the outside due to the temperature difference between the inside and outside, and the temperature near the opening rises. As a result, the air near the opening becomes water droplets, and when the door is closed again, the water droplets become ice and adhere to the vicinity of the opening. In this way, the adhesion of ice is accumulated each time the door is opened and closed, and a large ice lump is formed. As a result, there is a problem that the opening / closing door cannot be opened / closed smoothly due to the lump of ice formed in the vicinity of the opening, and the storage case for storing stored items cannot be smoothly put in / out. Moreover, the adhesion of the ice described above causes a temperature increase near the opening, and there is a problem that a load is applied to the compressor.

本発明は、上記課題を解決するためになされたものであり、開閉扉を開けた時の開口部付近に発生する氷の付着を最小限に抑えることができる超低温フリーザを提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an ultra-low temperature freezer capable of minimizing the adhesion of ice generated near the opening when the door is opened. To do.

本発明の第１の超低温フリーザによれば、保存物を貯蔵する複数の貯蔵ケースと、前記貯蔵ケースを収納する冷凍室を備えた本体と、前記本体に回動可能に取り付けられ、前記冷凍室の開口部を開閉する開閉扉と、前記冷凍室の開口部を塞ぐように取り付けられ、前記貯蔵ケースが挿入される挿入孔が複数形成された断熱パネルとを有する超低温フリーザであって、前記貯蔵ケースには、前記断熱パネルの挿入孔に挿入され、前記冷凍室内に収納された時に、前記断熱パネルとともに開口部を塞ぐ断熱部が設けられていることを特徴とするものである。   According to the first ultra-low temperature freezer of the present invention, a plurality of storage cases for storing stored items, a main body including a freezing chamber for storing the storage cases, and a freezer that is rotatably attached to the main body. An open / close door that opens and closes the opening of the freezing chamber, and a heat insulation panel that is attached so as to close the opening of the freezer compartment and in which a plurality of insertion holes into which the storage case is inserted is formed. The case is provided with a heat insulating portion that closes the opening together with the heat insulating panel when inserted into the insertion hole of the heat insulating panel and accommodated in the freezer compartment.

前記冷凍室の開口部は、前記本体の側面方向に形成されていてもよい。   The opening of the freezer compartment may be formed in the side surface direction of the main body.

前記冷凍室には、前記断熱パネルの挿入孔に挿入される貯蔵ケースをガイドするガイドレールが設けられていてもよい。   The freezer compartment may be provided with a guide rail for guiding a storage case inserted into the insertion hole of the heat insulating panel.

前記冷凍室の開口部は、前記本体の上面方向に形成されていてもよい。   The opening of the freezer compartment may be formed in the upper surface direction of the main body.

前記断熱パネルと前記冷凍室の底部との間に補強用支柱が設けられていてもよい。   A reinforcing column may be provided between the heat insulating panel and the bottom of the freezer compartment.

本発明の超低温フリーザによれば、貯蔵ケースが断熱パネルの挿入孔に挿入され、冷凍室内に収納された時に、貯蔵ケースの断熱部と断熱パネルとにより、冷凍室の開口部がほとんど塞がれる。従って、保存物の低温での温度維持を非常に良好にすることができる。また、開閉扉を開けて、保存物を取り出すために貯蔵ケースを引き出しても、引き出した部分から冷凍室内の冷気が流出されるだけであるので、従来に比べ、開口部付近の温度の上昇を抑制できる。その結果、開口部付近での氷の付着を最小限に抑えることができるので、開閉扉の開閉及び貯蔵ケースの出し入れをスムーズに行うことができる。また、氷の付着に伴う開口部付近の温度上昇を抑えることにより、コンプレッサの負荷を低減できる。   According to the ultra-low temperature freezer of the present invention, when the storage case is inserted into the insertion hole of the heat insulation panel and stored in the freezer compartment, the opening portion of the freezer compartment is almost blocked by the heat insulation portion and the heat insulation panel of the storage case. . Therefore, the temperature maintenance of the preserved product at a low temperature can be made very good. In addition, even if the storage case is pulled out to open the open / close door and the stored matter is taken out, only the cold air in the freezer compartment flows out from the drawn out portion, so the temperature near the opening is increased compared to the conventional case. Can be suppressed. As a result, it is possible to minimize the adhesion of ice in the vicinity of the opening, so that the opening / closing door and the storage case can be smoothly opened and closed. Moreover, the load on the compressor can be reduced by suppressing the temperature rise in the vicinity of the opening due to the adhesion of ice.
