Therefore, the work efficiency when the user takes out the container may deteriorate, and the quality of the sample may deteriorate.

　本発明は、上記のような従来の問題に鑑みてなされたものであって、その目的は、扉が開かれた際に白煙が発生することを抑制できる冷凍装置を提供することにある。 The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a freezing device capable of suppressing the generation of white smoke when the door is opened.

　前述した課題を解決する主たる本発明は、前面に開口を有する収納室と、前記収納室に設けられ、被冷却物を収納する複数の容器を収納する引き出し可能な引き出し部を、収納する箱状部材と、前記開口のうち、前記箱状部材と、前記収納室との隙間を覆う第１閉塞部材と、前記収納室を密閉するための外扉と、を備える冷凍装置である。 The main invention for solving the above-mentioned problems is a box shape for storing a storage chamber having an opening on the front surface and a pullable drawer portion provided in the storage chamber for storing a plurality of containers for storing objects to be cooled. A freezing device including a member, a first closing member that covers a gap between the box-shaped member and the storage chamber, and an outer door for sealing the storage chamber among the openings.

FIG. 2 is a perspective view of the freezer 20 with the heat insulating door open, and FIG. 3 is a diagram for explaining “section B” of the freezer 20. Further, FIG. 4 is a cross-sectional view of the freezer 20 when it is cut along the line XX of FIG.

　なお、以下、本実施形態においては、冷凍庫２０の構成の理解を容易にするために、冷凍庫２０の一部の構成（例えば、冷却装置３２や温度センサ４０）は、適宜省略されている。冷凍庫２０は、内箱５０、外箱５１、断熱扉５２を備えている。 Hereinafter, in the present embodiment, in order to facilitate understanding of the configuration of the freezer 20, a part of the configuration of the freezer 20 (for example, the cooling device 32 and the temperature sensor 40) is appropriately omitted. The freezer 20 includes an inner box 50, an outer box 51, and a heat insulating door 52.

　内箱５０は、直方体形状の部材であり、前面に開口５３を有している。なお、内箱５０によって区画される空間、つまり内箱５０の内側に形成される空間が収納室３０となる。 The inner box 50 is a rectangular parallelepiped member and has an opening 53 on the front surface. The space partitioned by the inner box 50, that is, the space formed inside the inner box 50 is the storage chamber 30.

　外箱５１は、断熱材等（不図示）を介して内箱５０の周囲を囲む直方体形状の筐体であり、断熱扉５２は、冷凍庫２０を密閉するための外扉である。 The outer box 51 is a rectangular parallelepiped housing that surrounds the inner box 50 via a heat insulating material or the like (not shown), and the heat insulating door 52 is an outer door for sealing the freezer 20.

　また、本実施形態では、収納室３０の開口５３が設けられている方向を「前」とし、逆側を「後」とする。また、冷凍庫２０において、断熱扉５２が取り付けられた方向を「左」とし、逆側を「右」とする。さらに、冷凍庫２０の底面側を「下」とし、逆側を「上」とする。なお、「上下方向」は、「前後方向」及び「左右方向」と直交する方向でもある。 Further, in the present embodiment, the direction in which the opening 53 of the storage chamber 30 is provided is "front", and the opposite side is "rear". Further, in the freezer 20, the direction in which the heat insulating door 52 is attached is "left", and the opposite side is "right". Further, the bottom side of the freezer 20 is "bottom" and the opposite side is "top". The "vertical direction" is also a direction orthogonal to the "front-back direction" and the "left-right direction".

　収納室３０には、棚６２（後述）よって区切られた、“区画Ａ”と、“区画Ｂ”とが形成されている。なお、棚６２の上側の“区画Ａ”は、「第１区画」に相当し、棚６２の下側の“区画Ｂ”は、「第２区画」に相当する。 The storage room 30 is formed with "section A" and "section B" separated by a shelf 62 (described later). The "section A" on the upper side of the shelf 62 corresponds to the "first section", and the "section B" on the lower side of the shelf 62 corresponds to the "second section".

　収納室３０のうち、“区画Ａ”は、例えば、長期保存される検体等を収納する区画であり、“区画Ａ”には、棚６１，６２、内扉６３，６４が設けられている。 Of the storage chamber 30, "section A" is, for example, a section for storing a sample or the like to be stored for a long period of time, and "section A" is provided with shelves 61, 62 and inner doors 63, 64.

　棚６１，６２は、検体等の被冷却物が収納されるラック（不図示）を支持する部材であり、内箱５０の内側に取り付けられている。また、棚６１，６２は、網目形状の棚であるため、収納室３０の“区画Ａ”と、“区画Ｂ”とは、連通される。 The shelves 61 and 62 are members that support a rack (not shown) in which objects to be cooled such as specimens are stored, and are attached to the inside of the inner box 50. Further, since the shelves 61 and 62 are mesh-shaped shelves, the "section A" and the "section B" of the storage chamber 30 are communicated with each other.

　内扉６３は、“区画Ａ”の開口５３ａのうち、棚６１より上側の区画の開口を覆う扉であり、内扉６４は、“区画Ａ”の開口５３ａのうち、棚６１，６２で挟まれた区画の開口を覆う扉である。このため、内扉６３，６４が閉じられることにより、“区画Ａ”の開口５３ａ（第１開口）は覆われることになる。 The inner door 63 is a door that covers the opening of the section above the shelf 61 in the opening 53a of the “section A”, and the inner door 64 is sandwiched between the shelves 61 and 62 in the opening 53a of the “section A”. It is a door that covers the opening of the section. Therefore, by closing the inner doors 63 and 64, the opening 53a (first opening) of the "section A" is covered.

　収納室３０のうち、“区画Ｂ”は、例えば、取り出し頻度の高い検体等を収納する区画であり、“区画Ｂ”には、ラック６５ａ～６５ｃ、閉塞部材６６～６８が設けられている。 Of the storage chamber 30, the "section B" is, for example, a section for storing a sample or the like that is frequently taken out, and the "section B" is provided with racks 65a to 65c and closing members 66 to 68.

　ラック６５ａは、検体等が収納される容器を複数収納する引き出し部１００（後述）を、４つ収納する直方体状の「箱状部材」である。また、ラック６５ｂ，６５ｃは、ラック６５ａと同じ形状の部材である。そして、収納室３０の底面には、ラック６５ｂを挟み込むよう、３つのラック６５ａ～６５ｃは、隙間なく置かれている。なお、ラック６５ａ～６５ｃの詳細な構造については後述する。 The rack 65a is a rectangular parallelepiped "box-shaped member" that stores four drawers 100 (described later) for storing a plurality of containers for storing specimens and the like. Further, the racks 65b and 65c are members having the same shape as the rack 65a. The three racks 65a to 65c are placed on the bottom surface of the storage chamber 30 without gaps so as to sandwich the rack 65b. The detailed structure of the racks 65a to 65c will be described later.

　閉塞部材６６～６８は、“区画Ｂ”の開口５３ｂ（第２開口）のうち、ラック６５ａ～６５ｃと、“区画Ｂ”との隙間（以下、“隙間Ｇ”とする。）を塞ぐよう、取り付けられる板状部材である。なお、閉塞部材６６～６８は、内箱５０と同じ、アルミニウム等の材質で製造された部材であり、「第１閉塞部材」に相当する。 The closing members 66 to 68 close the gap between the racks 65a to 65c and the "section B" (hereinafter referred to as "gap G") in the opening 53b (second opening) of the "section B". It is a plate-shaped member that can be attached. The closing members 66 to 68 are the same members as the inner box 50 and are made of a material such as aluminum, and correspond to the "first closing member".

　閉塞部材６６は、ラック６５ａ～６５ｃが設置された後、“隙間Ｇ”のうち、ラック６５ａの左側と、“区画Ｂ”との隙間を覆う板状部材であり、例えば収納室３０の左側の側面と、ラック６５ａと、に取り付けられる。 The closing member 66 is a plate-shaped member that covers the gap between the left side of the rack 65a and the “compartment B” in the “gap G” after the racks 65a to 65c are installed, and is, for example, the left side of the storage chamber 30. It is attached to the side surface and the rack 65a.

　閉塞部材６７は、ラック６５ａ～６５ｃが設置された後、“隙間Ｇ”のうち、ラック６５ｃの右側と、“区画Ｂ”との隙間を覆う板状部材であり、例えば収納室３０の右側の側面と、ラック６５ｃと、に取り付けられる。なお、本実施形態の閉塞部材６６，６７の上下方向の長さは、ラック６５ａ，６５ｂの高さと等しい。 The closing member 67 is a plate-shaped member that covers the gap between the right side of the rack 65c and the “compartment B” in the “gap G” after the racks 65a to 65c are installed, and is, for example, the right side of the storage chamber 30. It is attached to the side surface and the rack 65c. The vertical lengths of the closing members 66 and 67 of the present embodiment are equal to the heights of the racks 65a and 65b.

　閉塞部材６８は、ラック６５ａ～６５ｃと、閉塞部材６６，６７と、が設置された後、“隙間Ｇ”のうち、ラック６５ａ～６５ｃ及び閉塞部材６６，６７の上側と、“区画Ｂ”との隙間を覆う板状部材である。閉塞部材６８は、例えば、収納室３０の左右の側面と、棚６２と、に取り付けられる。 After the racks 65a to 65c and the closing members 66 and 67 are installed, the closing member 68 includes the upper side of the racks 65a to 65c and the closing members 66 and 67 and the "section B" in the "gap G". It is a plate-shaped member that covers the gap between the two. The closing member 68 is attached to, for example, the left and right side surfaces of the storage chamber 30 and the shelves 62.

　なお、詳細は後述するが、引き出し部１００は、ラック６５に収納されると、ラック６５の挿入口を覆う形状をしている。このため、ラック６５ａ～６５ｃに、１２個の全ての引き出し部１００が収納されると、“区画Ｂ”の開口５３ｂは、引き出し部１００と、閉塞部材６６～６８とで、覆われることになる。 Although details will be described later, the drawer portion 100 has a shape that covers the insertion port of the rack 65 when it is stored in the rack 65. Therefore, when all 12 drawers 100 are housed in the racks 65a to 65c, the opening 53b of the "section B" is covered by the drawers 100 and the closing members 66 to 68. ..

　そして、このような状態で、“区画Ａ”の内扉６３，６４が閉じられると、収納室３０の前面の開口５３、つまり、“区画Ａ”の開口５３ａと、“区画Ｂ”の開口５３ｂの両方は、覆われることになる。 Then, when the inner doors 63 and 64 of the "section A" are closed in such a state, the opening 53 on the front surface of the storage chamber 30, that is, the opening 53a of the "section A" and the opening 53b of the "section B" Both will be covered.

＜＜＜白煙について＞＞＞
　つぎに、収納室３０の冷たい空気と、収納室３０の外の空気とで発生する“白煙”について説明する。一般に、“白煙”は、収納室３０の冷たい空気と、収納室３０の外の空気とが、冷凍庫２０の庫外で混ざり合うことで、外気中の水蒸気が液体または氷の粒となって発生する霧である。霧は空気より重いので、下方に溜まる傾向にある。冷たい空気が流体の場合、表面近傍で外気と冷気が交じり合って、霧が発生する。外気と冷気の交じり合う層が厚いと、霧による視認度の低下が発生する。流体表面での霧の発生する層の厚みは、流体の速度に依存する。速度が速いと霧の層は薄く。速度が緩慢であれば、霧の層は厚くなる。 <<< About white smoke >>>
Next, the "white smoke" generated by the cold air in the storage chamber 30 and the air outside the storage chamber 30 will be described. Generally, in "white smoke", the cold air in the storage chamber 30 and the air outside the storage chamber 30 are mixed outside the freezer 20, so that the water vapor in the outside air becomes liquid or ice particles. It is the fog that occurs. Fog is heavier than air and tends to collect downwards. When cold air is a fluid, the outside air and cold air mix near the surface to generate fog. If the layer where the outside air and the cold air mix is thick, the visibility will be reduced due to fog. The thickness of the mist-generating layer on the surface of the fluid depends on the velocity of the fluid. The faster the speed, the thinner the fog layer. If the speed is slow, the fog layer will thicken.

　収納室３０からの冷たい空気が緩やかに放出される場合、冷たい空気と、収納室３０の外の空気とが混ざり易くなるため、より多くの“白煙”が発生する傾向がある。また、白煙は水蒸気の凝縮または昇華により発生する霧が要因のため冷気温度が大きく影響する。－６０℃以下の冷凍機では白煙の発生が顕著になる。 When the cold air from the storage chamber 30 is slowly discharged, the cold air and the air outside the storage chamber 30 are likely to be mixed, so that more "white smoke" tends to be generated. In addition, white smoke is greatly affected by the cold air temperature because of the fog generated by the condensation or sublimation of water vapor. White smoke is noticeably generated in a refrigerator at -60 ° C or lower.

　ここで、本実施形態の冷凍庫２０において、例えば、ラック６５ａの最上段の引き出し部１００が引き出されると、ラック６５ａの最上段の挿入口（後述）を介して、収納室３０の冷たい空気が、収納室３０の外に放出される。 Here, in the freezer 20 of the present embodiment, for example, when the uppermost drawer portion 100 of the rack 65a is pulled out, the cold air of the storage chamber 30 is released through the uppermost insertion port (described later) of the rack 65a. It is discharged to the outside of the storage chamber 30.

　一方、“区画Ｂ”に閉塞部材６６～６８が取り付けられていない場合に、ラック６５ａの最上段の引き出し部１００が引き出されると、ラック６５ａの最上段の挿入口（後述）と、“隙間Ｇ”と、を介して、収納室３０の空気が外に放出される。 On the other hand, when the closing members 66 to 68 are not attached to the "section B" and the uppermost drawer portion 100 of the rack 65a is pulled out, the uppermost insertion port (described later) of the rack 65a and the "gap G" ", The air in the storage chamber 30 is released to the outside through.

　したがって、冷凍庫２０は、“区画Ｂ”に閉塞部材６６～６８が取り付けられていない場合と比較すると、狭い隙間を介して、収納室３０の冷たい空気を放出する。このため、冷凍庫２０からは、冷たい空気が、より早い速度で庫外に放出されることになり、冷たい空気と、収納室３０の外の空気と、が混ざりにくくなる。この結果、冷凍庫２０では、“区画Ｂ”に閉塞部材６６～６８を設けることにより、“白煙”の発生を抑制できる。 Therefore, the freezer 20 discharges the cold air of the storage chamber 30 through a narrow gap as compared with the case where the closing members 66 to 68 are not attached to the "section B". Therefore, the cold air is discharged from the freezer 20 to the outside of the freezer at a faster speed, and the cold air and the air outside the storage chamber 30 are less likely to be mixed. As a result, in the freezer 20, the generation of "white smoke" can be suppressed by providing the closing members 66 to 68 in the "section B".

　また、本実施形態では、収納室３０の冷たく、重い空気を、より早い速度で放出させるため、ラック６５を、収納室３０の２つの区画のうち、底面側の“区画Ａ”に設置している。さらに、詳細は後述するが、引き出し部１００、容器を収納する収納箱には、空気を円滑に庫外へ流す流路が形成されている。以下、ラック６５、引き出し部１００、容器を収納する収納箱等の詳細について説明する。 Further, in the present embodiment, in order to release the cold and heavy air of the storage chamber 30 at a higher speed, the rack 65 is installed in the "compartment A" on the bottom side of the two compartments of the storage chamber 30. There is. Further, as will be described in detail later, the drawer portion 100 and the storage box for accommodating the container are formed with a flow path for smoothly flowing air to the outside of the refrigerator. Hereinafter, details of the rack 65, the drawer portion 100, the storage box for storing the container, and the like will be described.

　白煙に対する、流路の効果について説明する。前述したように、冷気と外気が混合されると霧が発生して白煙となる。冷気と外気が混合する層の厚みは冷気流体の速度に依存するが、別の要因として冷気流体への抵抗の影響がある。流体抵抗が大きいと流体の流れが乱され表面積が増えるため、周辺の外気とより多く接触する。その結果、霧の発生する量が大きくなり視認度が低下する。乱流の発生を抑えるためには、流体への抵抗をできるだけ小さくする必要がある。流路を作ることで流体への抵抗を小さくできる。 << Effect of flow path >>
The effect of the flow path on white smoke will be described. As mentioned above, when cold air and outside air are mixed, fog is generated and becomes white smoke. The thickness of the layer where cold air and outside air are mixed depends on the velocity of the cold air fluid, but another factor is the influence of resistance to the cold air fluid. If the fluid resistance is large, the flow of the fluid is disturbed and the surface area increases, so that the contact with the surrounding outside air increases. As a result, the amount of fog generated increases and the visibility decreases. In order to suppress the generation of turbulence, it is necessary to reduce the resistance to the fluid as much as possible. The resistance to the fluid can be reduced by creating a flow path.

＜＜＜ラック６５の詳細＞＞＞
　図５は、ラック６５の構成を説明するための斜視図であり、図６は、ラック６５の断面図である。なお、３つのラック６５ａ～６５ｃの構造は同じであるため、ここでは、便宜上、ラック６５ａ～６５ｃを区別せず、単に、ラック６５として説明している。 <<< Details of Rack 65 >>>
FIG. 5 is a perspective view for explaining the configuration of the rack 65, and FIG. 6 is a cross-sectional view of the rack 65. Since the structures of the three racks 65a to 65c are the same, the racks 65a to 65c are not distinguished here for convenience, and are simply described as racks 65.

　ラック６５は、引き出し部１００を４つ収納可能な直方体形状の箱状部材であり、内側には、引き出し部１００を支持するＬ字型のレール２２０ａ～２２０ｄ，２２１ａ～２２１ｄが設けられている。 The rack 65 is a rectangular parallelepiped-shaped box-shaped member that can store four drawers 100, and L-shaped rails 220a to 220d and 221a to 221d that support the drawers 100 are provided inside.

　具体的には、ラック６５の底面２００から垂直に延びる側面２０１には、所定の間隔で、４つのレール２２０ａ～２２０ｄが取り付けられている。また、底面２００から垂直に延び、側面２０１に対向する側面２０２には、レール２２０ａ～２２０ｄの夫々に対応するよう、レール２２１ａ～２２１ｄが取り付けられている。具体的には、レール２２０ａ～２２０ｄの夫々が取り付けられた高さと同じ高さに、レール２２１ａ～２２１ｄが取り付けられている。 Specifically, four rails 220a to 220d are attached to the side surface 201 extending vertically from the bottom surface 200 of the rack 65 at predetermined intervals. Further, rails 221a to 221d are attached to the side surfaces 202 that extend vertically from the bottom surface 200 and face the side surface 201 so as to correspond to the rails 220a to 220d, respectively. Specifically, the rails 221a to 221d are mounted at the same height as the rails 220a to 220d, respectively.

　そして、本実施形態では、レール２２０ａ～２２０ｄと、レール２２０ａ～２２０ｄとのうち、向かい合う１組のレールのそれぞれが、引き出し部１００を支持する。 Then, in the present embodiment, each of the rails 220a to 220d and the rails 220a to 220d facing each other supports the drawer portion 100.

　具体的には、レール２２０ａ，２２１ａは、ラック６５の最上段の挿入口２５０ａを介して挿入される引き出し部１００を支持し、レール２２０ｂ，２２１ｂは、ラック６５の上から２段目の挿入口２５０ｂを介して挿入される引き出し部１００を支持する。 Specifically, the rails 220a and 221a support the drawer portion 100 to be inserted through the uppermost insertion port 250a of the rack 65, and the rails 220b and 221b are the second insertion ports from the top of the rack 65. The drawer portion 100 inserted via the 250b is supported.

　また、レール２２０ｃ，２２１ｃは、ラック６５の下から２段目の挿入口２５０ｃを介して挿入される引き出し部１００を支持し、レール２２０ｄ，２２１ｄは、ラック６５の最下段の挿入口２５０ｄを介して挿入される引き出し部１００を支持する。 Further, the rails 220c and 221c support the drawer portion 100 inserted through the second-stage insertion port 250c from the bottom of the rack 65, and the rails 220d and 221d pass through the lowermost insertion port 250d of the rack 65. Supports the drawer portion 100 to be inserted.

　また、ラック６５の上面２０３には、開口２１０が設けられ、後方の背面２０４には、開口２１１が設けられている。 Further, the upper surface 203 of the rack 65 is provided with an opening 210, and the rear rear surface 204 is provided with an opening 211.

　開口２１０，２１１は、引き出し部１００が、ラック６５から引き出される際に、収納室３０内の空気を、効率良く取り込むための「取り込み口」である。このため、引き出し部１００が引き出される際には、ラック６５の、収納室３０内の空気は、開口２１０，２１１、挿入口２５０を介して外へ放出される。なお、開口２１０，２１１は、空気が取り込めれば良いため、形状はどのような形であっても良い。 The openings 210 and 211 are "take-in ports" for efficiently taking in the air in the storage chamber 30 when the drawer portion 100 is pulled out from the rack 65. Therefore, when the drawer portion 100 is pulled out, the air in the storage chamber 30 of the rack 65 is discharged to the outside through the openings 210, 211 and the insertion port 250. The openings 210 and 211 may have any shape as long as air can be taken in.

　また、本実施形態のラック６５の側面２０１，２０２の間には、４枚のアンテナ基板３００ａ～３００ｄが設置されている。 Further, four antenna boards 300a to 300d are installed between the side surfaces 201 and 202 of the rack 65 of the present embodiment.

　アンテナ基板３００ａは、レール２２０ａ，２２１ａの長手方向に沿って延びる板状の部材であり、例えば、アンテナ４００を表面に１００個有する。アンテナ４００は、引き出し部１００に収納された複数の容器のそれぞれ無線タグの情報を読み取るためのパターンアンテナ等であり、配線ケーブル（不図示）を介して、庫外の読取装置２１に接続される。 The antenna substrate 300a is a plate-shaped member extending along the longitudinal direction of the rails 220a and 221a, and has, for example, 100 antennas 400 on its surface. The antenna 400 is a pattern antenna or the like for reading the information of the wireless tags of each of the plurality of containers housed in the drawer 100, and is connected to the reading device 21 outside the refrigerator via a wiring cable (not shown). ..

　また、アンテナ基板３００ａは、レール２２０ａ，２２１ａに支持された引き出し部１００に収納された複数の容器のそれぞれ無線タグの情報を、アンテナ４００が読みとることができるよう、レール２２０ａ，２２１ａの下側に取り付けられている。なお、ここでは、アンテナ基板３００ａについて説明したが、アンテナ基板３００ｂ～３００ｄについても、アンテナ基板３００ａと同様である。 Further, the antenna substrate 300a is placed on the lower side of the rails 220a and 221a so that the antenna 400 can read the information of the wireless tags of the plurality of containers housed in the drawers 100 supported by the rails 220a and 221a. It is attached. Although the antenna board 300a has been described here, the antenna boards 300b to 300d are the same as the antenna board 300a.

＜＜＜容器８０の詳細＞＞＞
　図７は、検体（不図示）を収納する容器８０の一例を示す図である。容器８０は、底面に、無線タグ８５（ＲＦ（Radio-frequency）タグ）が付された円筒形状の容器である。容器８０の本体には、本体の内側の空間を密閉するとともに、取り外し可能な蓋が取り付けられている。 <<< Details of Container 80 >>>
FIG. 7 is a diagram showing an example of a container 80 for storing a sample (not shown). The container 80 is a cylindrical container having a radio tag 85 (RF (Radio-frequency) tag) attached to the bottom surface. The main body of the container 80 is provided with a removable lid while sealing the space inside the main body.

　無線タグ８５は、例えばアンテナ４００からの電波を受信すると、識別コードを送信する受動型のタグである。なお、「識別コード」は、無線タグ８５に記憶された固有の識別情報であり、例えば５ビットの数字を示すデータである。 The wireless tag 85 is, for example, a passive tag that transmits an identification code when receiving a radio wave from the antenna 400. The "identification code" is unique identification information stored in the wireless tag 85, and is data indicating, for example, a 5-bit number.

　本実施形態では、例えば容器８０に収納される検体の情報が、識別コードに紐付けされて、記憶装置２３に記憶されている。具体的には、例えば容器８０に収納された検体が「Ａさんの血液」であり、保存期間が「２年」である場合、それらの情報が、容器８０に付された無線タグ８５の識別コード（例えば、“００００１”）とともに、記憶装置２３に記憶されている。 In the present embodiment, for example, the information of the sample stored in the container 80 is associated with the identification code and stored in the storage device 23. Specifically, for example, when the sample stored in the container 80 is "Mr. A's blood" and the storage period is "2 years", the information is used to identify the wireless tag 85 attached to the container 80. It is stored in the storage device 23 together with the code (for example, “00001”).

＜＜＜収納箱９０の詳細＞＞＞
　図８は、収納箱９０を説明するための図である。収納箱９０の内側の底面には、容器８０を１つずつ分けて収納可能な所定の凹みが２５個設けられている。そして、容器８０は、収納箱９０の底面の凹みに挿入されることにより、容器８０は、収納箱９０に装着される。 <<< Details of storage box 90 >>>
FIG. 8 is a diagram for explaining the storage box 90. On the inner bottom surface of the storage box 90, 25 predetermined recesses that can store the containers 80 separately are provided. Then, the container 80 is attached to the storage box 90 by being inserted into the recess on the bottom surface of the storage box 90.

　蓋９１は、収納箱９０の開口を覆いつつ、取り外し可能に収納箱９０に取り付けられる。また、蓋９１の表面には、蓋９１が取り付けられた収納箱９０が、引き出し部１００に収納された際、引き出し部１００の長手方向に沿って延びる凹部９２が形成されている。 The lid 91 is detachably attached to the storage box 90 while covering the opening of the storage box 90. Further, on the surface of the lid 91, a recess 92 is formed which extends along the longitudinal direction of the drawer portion 100 when the storage box 90 to which the lid 91 is attached is stored in the drawer portion 100.

　なお、詳細は後述するが、凹部９２は、引き出し部１００が引き出される際に、収納室３０内の空気を、引き出し部１００が引き出される方向に沿って、収納室３０の外に流す“流路Ｐ２”に相当する。 Although the details will be described later, the recess 92 allows the air in the storage chamber 30 to flow out of the storage chamber 30 along the direction in which the drawer portion 100 is drawn out when the drawer portion 100 is pulled out. Corresponds to "P2".

　本実施形態の凹部９２は、蓋９１に１つのみ設けられているが、複数設けられていても良い。また、凹部９２は、空気が円滑に流れる形状を有していれば良いため、図８の形状に限られない。さらに、凹部９２は、蓋９１の左右方向の中央に設けられているが、蓋９１の端部等、中央以外の場所に形成されていても良い。 Although only one recess 92 of the present embodiment is provided in the lid 91, a plurality of recesses 92 may be provided. Further, the recess 92 is not limited to the shape shown in FIG. 8 as long as it has a shape through which air flows smoothly. Further, although the recess 92 is provided at the center of the lid 91 in the left-right direction, it may be formed at a place other than the center such as the end of the lid 91.

＜＜＜引き出し部１００の詳細＞＞＞
　図９は引き出し部１００の一部を分解した斜視図であり、図１０は、収納箱９０と引き出し部１００との関係を説明するための図である。また、図１１は、引き出し部１００等を、図１０のＸ－Ｘ線で切断した際の断面図である。 <<< Details of drawer 100 >>>
FIG. 9 is an exploded perspective view of a part of the drawer portion 100, and FIG. 10 is a diagram for explaining the relationship between the storage box 90 and the drawer portion 100. Further, FIG. 11 is a cross-sectional view when the drawer portion 100 and the like are cut by the XX line of FIG.

　引き出し部１００は、上面に開口を有し、収納箱９０を４つ収納する直方体形状の箱状部材であり、底面板１２０、側面板１２１，１２２、背面板１２３、前面板１２４、底板１５０，１５１を含む
　引き出し部１００において、収納箱９０を収納する空間は、底面板１２０、側面板１２１，１２２、背面板１２３、前面板１２４の合計５枚の平板で囲まれることによって形成される。そして、引き出し部１００には、収納箱９０を、引き出し部１００の所定の収納位置に収納させるための、仕切り板１４０ａ～１４０ｃ、１４１ａ～１４１ｃが設けられている。 The drawer portion 100 is a rectangular parallelepiped box-shaped member having an opening on the upper surface and accommodating four storage boxes 90, and is a bottom plate 120, side plates 121, 122, back plate 123, front plate 124, bottom plate 150, In the drawer portion 100 including 151, the space for storing the storage box 90 is formed by being surrounded by a total of five flat plates of the bottom plate 120, the side plates 121 and 122, the back plate 123, and the front plate 124. Then, the drawer portion 100 is provided with partition plates 140a to 140c and 141a to 141c for storing the storage box 90 in a predetermined storage position of the drawer portion 100.

　具体的には、仕切り板１４０ａ～１４０ｃの夫々は、底面板１２０から垂直に延びる側面板１２１の長手方向に沿って、等間隔に設けられている。 Specifically, the partition plates 140a to 140c are provided at equal intervals along the longitudinal direction of the side plate 121 extending vertically from the bottom plate 120.

　また、仕切り板１４１ａ～１４１ｃの夫々も同様に、底面板１２０から垂直に延び、側面板１２１に対向する側面板１２２の長手方向に沿って、等間隔に設けられている。 Similarly, each of the partition plates 141a to 141c extends vertically from the bottom plate 120 and is provided at equal intervals along the longitudinal direction of the side plate 122 facing the side plate 121.

　ここでは、仕切り板１４０ａ～１４０ｃの夫々に対向する位置に、仕切り板１４１ａ～１４１ｃが設けられるため、引き出し部１００には、区切られた４つの空間が形成される。そして、本実施形態では、区切られた４つの空間の何れかに収納箱９０が収納されると、収納箱９０は、底面板１２０に垂直な方向以外には動かなくなるよう、仕切り板１４０，１４１の位置が定められている。 Here, since the partition plates 141a to 141c are provided at positions facing each of the partition plates 140a to 140c, four divided spaces are formed in the drawer portion 100. Then, in the present embodiment, when the storage box 90 is stored in any of the four divided spaces, the storage box 90 does not move except in the direction perpendicular to the bottom plate 120, so that the partition plates 140, 141 The position of is determined.

　そして、図１０に示すように、区切られた４つの空間の全てに、蓋９１が取り付けられた収納箱９０が収納されると、引き出し部１００が引き出される際に、収納室３０の空気を外に流す、４つの凹部９２による“流路Ｐ２”が形成されることになる。 Then, as shown in FIG. 10, when the storage box 90 to which the lid 91 is attached is stored in all four divided spaces, the air in the storage chamber 30 is removed when the drawer portion 100 is pulled out. A "flow path P2" is formed by the four recesses 92 flowing into the air.

　ところで、本実施形態では、収納箱９０は、２５個の容器８０を収納でき、引き出し部１００は、４つの収納箱９０を収納できる。このため、引き出し部１００には、最大で１００個の容器８０が収納されることになる。 By the way, in the present embodiment, the storage box 90 can store 25 containers 80, and the drawer 100 can store four storage boxes 90. Therefore, a maximum of 100 containers 80 can be stored in the drawer portion 100.

　また、本実施形態では、１００個の容器８０を収納する引き出し部１００がラック６５に収納された場合、１００個の容器８０は、アンテナ基板３００の１００個のアンテナ４００のそれぞれに対応する位置に収納される。 Further, in the present embodiment, when the drawer portion 100 for accommodating 100 containers 80 is housed in the rack 65, the 100 containers 80 are positioned at positions corresponding to each of the 100 antennas 400 of the antenna board 300. It is stored.

　さらに、引き出し部１００の底面板１２０には、中央に面積の大きい開口１３０が設けられている。これにより、アンテナ４００は、高い精度で、無線タグ８５の情報を読み取ることができる。 Further, the bottom plate 120 of the drawer portion 100 is provided with an opening 130 having a large area in the center. As a result, the antenna 400 can read the information of the wireless tag 85 with high accuracy.

　底板１５０，１５１は、引き出し部１００が引き出される際に、引き出し部１００が引き出される方向に沿って、収納室３０の外に流す“流路Ｐ１”を形成するための部材である。本実施形態では、底板１５０，１５１は、前後方向に伸びる板状部材であり、底面板１２０の開口１３０を塞がないよう、底面板１２０の長手方向に沿って取り付けられている。 The bottom plates 150 and 151 are members for forming a "flow path P1" that flows out of the storage chamber 30 along the direction in which the drawer portion 100 is pulled out when the drawer portion 100 is pulled out. In the present embodiment, the bottom plates 150 and 151 are plate-shaped members extending in the front-rear direction, and are attached along the longitudinal direction of the bottom plate 120 so as not to block the opening 130 of the bottom plate 120.

　そして、底板１５０，１５１は、引き出し部１００がラック６５に収納される際に、レール２２０，２２１に支持される。この結果、図１１に示すように、引き出し部１００の底面側には、底板１５０，１５１の上下方向の厚みに応じた隙間が、“流路Ｐ１”として形成されることになる。なお、“流路Ｐ１”は、「第１流路」に相当し、“流路Ｐ２”は、「第２流路」に相当する。 Then, the bottom plates 150 and 151 are supported by the rails 220 and 221 when the drawer portion 100 is stored in the rack 65. As a result, as shown in FIG. 11, a gap corresponding to the thickness of the bottom plates 150 and 151 in the vertical direction is formed as the "flow path P1" on the bottom surface side of the drawer portion 100. The "flow path P1" corresponds to the "first flow path", and the "flow path P2" corresponds to the "second flow path".

　また、図１２は、引き出し部１００が、図３で示したラック６５の最上段の挿入口２５０ａに挿入され、収納された状態を示す図である。 Further, FIG. 12 is a diagram showing a state in which the drawer portion 100 is inserted into and stored in the uppermost insertion port 250a of the rack 65 shown in FIG.

　ここで、図１２と、図３とを比較すると明らかなように、本実施形態の引き出し部１００の前面板１２４は、引き出し部１００が、ラック６５の最上段に収納された状態では、挿入口２５０ａを覆う形状を有している。このため、例えば、ラック６５の全ての挿入口２５０ａ～２５０ｄに、引き出し部１００が収納されると、ラック６５の前面の開口（すなわち、挿入口２５０ａ～２５０ｄの全て）は、覆われることになる。 Here, as is clear from a comparison between FIGS. 12 and 3, the front plate 124 of the drawer portion 100 of the present embodiment has an insertion slot when the drawer portion 100 is housed in the uppermost stage of the rack 65. It has a shape that covers 250a. Therefore, for example, when the drawer portion 100 is housed in all the insertion ports 250a to 250d of the rack 65, the openings on the front surface of the rack 65 (that is, all the insertion ports 250a to 250d) are covered. ..

　これにより、例えば、４つの引き出し部１００のうち、１つのみが引き出された際には、引き出された引き出し部１００を介して放出される空気の速度は上昇することになる。 As a result, for example, when only one of the four drawers 100 is pulled out, the velocity of the air discharged through the drawn out 100 is increased.

　なお、本実施形態では、引き出し部１００の底面に底板１５０，１５１を用いて“流路Ｐ１”を形成することとしたが、例えば、引き出し部１００の側面に余裕があれば、側面に流路を形成しても良い。つまり、引き出し部１００に“流路Ｐ１”が形成できれば、“流路Ｐ１”の位置は、どの様な位置であっても良い。 In the present embodiment, the bottom plates 150 and 151 are used to form the "flow path P1" on the bottom surface of the drawer portion 100. For example, if there is a margin on the side surface of the drawer portion 100, the flow path is on the side surface. May be formed. That is, the position of the "flow path P1" may be any position as long as the "flow path P1" can be formed in the drawer portion 100.

＜＜＜空気の流れ＞＞＞
　図１３は、引き出し部１００が引き出された際の空気の流れの一例を示す図である。ここでは、“所望の容器”を取得すべく、利用者が断熱扉５２（不図示）を開放し、例えば、ラック６５ｂの上から２段目の引き出し部１００を引き出したこととする。なお、利用者が取得すべき“所望の容器”の位置は、例えば、アンテナ４００で容器の無線タグ８５の情報を取得させることにより、予め把握されている。 <<< Air flow >>>
FIG. 13 is a diagram showing an example of the air flow when the drawer portion 100 is pulled out. Here, it is assumed that the user opens the heat insulating door 52 (not shown) and pulls out the second drawer portion 100 from the top of the rack 65b in order to acquire the “desired container”. The position of the "desired container" to be acquired by the user is grasped in advance by, for example, having the antenna 400 acquire the information of the wireless tag 85 of the container.

　引き出し部１００が引き出されると、ラック６５ｂの挿入口２５０ｂを覆っていた、引き出し部１００の前面板１２４も前方向に移動する。この結果、収納室３０の“区画Ａ”の冷たい空気は、“区画Ｂ”のラック６５ｂの開口２１０，２１１、引き出し部１００の底面側の“流路Ｐ１”及び、引き出し部１００の上側の“流路Ｐ２”、挿入口２５０ｂを介し、庫外に放出される。 When the drawer portion 100 is pulled out, the front plate 124 of the drawer portion 100, which covers the insertion port 250b of the rack 65b, also moves forward. As a result, the cold air in the "compartment A" of the storage chamber 30 is the openings 210, 211 of the rack 65b in the "compartment B", the "flow path P1" on the bottom side of the drawer 100, and the "flow path P1" on the upper side of the drawer 100. It is discharged to the outside of the refrigerator through the flow path P2 ”and the insertion port 250b.

　なお、図１３において、開口２１０，２１１、“流路Ｐ１”、挿入口２５０ｂの経路は、“実線”で示され、開口２１０，２１１、“流路Ｐ２”、挿入口２５０ｂの経路は、“一点鎖線”で示されている。 In FIG. 13, the paths of the openings 210, 211, “flow path P1” and the insertion port 250b are indicated by “solid lines”, and the paths of the openings 210, 211, “flow path P2” and the insertion port 250b are “1”. It is indicated by a alternate long and short dash line.

　ここで、ラック６５は、収納室３０の２つの区画のうち、底面側の“区画Ｂ”に設けられている。そして、冷やされ、密度の高くなった収納室３０の空気は、底面側の“区画Ｂ”の挿入口２５０ｂを介して放出されるため、放出される際の速度は速くなる。この結果、冷たい空気と、庫外の空気とは、簡単には混ざり合うことが少なくなるため、“白煙”の発生は抑制される。 Here, the rack 65 is provided in "compartment B" on the bottom side of the two compartments of the storage chamber 30. Then, the air in the storage chamber 30 that has been cooled and has a high density is discharged through the insertion port 250b of the “section B” on the bottom surface side, so that the speed at which the air is discharged becomes high. As a result, the cold air and the air outside the refrigerator are less likely to be easily mixed with each other, so that the generation of "white smoke" is suppressed.

　この結果、例えば、利用者の視界が遮られることはないため、利用者は、引き出し部１００から、“所望の容器”を短時間で特定し、取り出すことができる。これにより、引き出し部１００に収納された容器の検体の質の劣化を防ぐことができる。 As a result, for example, since the user's field of view is not obstructed, the user can identify and take out the "desired container" from the drawer 100 in a short time. This makes it possible to prevent deterioration of the quality of the sample in the container stored in the drawer 100.

＜＜冷凍庫２５（区画Ｂ）の他の実施形態＞＞
　図１４は、冷凍庫２５の斜視図である。図１４の冷凍庫２５と、図１の冷凍庫２０とで、同じ符号が付されたブロックは同じである。冷凍庫２５では、“区画Ｂ”において、冷凍庫２０と異なりラック６５ａ～６５ｃが離されて収納室３０に設置されている。 << Other Embodiments of Freezer 25 (Section B) >>
FIG. 14 is a perspective view of the freezer 25. The blocks with the same reference numerals are the same in the freezer 25 of FIG. 14 and the freezer 20 of FIG. In the freezer 25, unlike the freezer 20, racks 65a to 65c are separated from each other and installed in the storage chamber 30 in "section B".

　冷凍庫２５では、上述した閉塞部材６６～６８に加え、ラック６５ａと、ラック６５ｂとの隙間を覆う閉塞部材６９ａと、ラック６５ｂと、ラック６５ｃとの隙間を覆う閉塞部材６９ｂと、が“区画Ｂ”に設けられている。 In the freezer 25, in addition to the above-mentioned closing members 66 to 68, the closing member 69a covering the gap between the rack 65a and the rack 65b, and the closing member 69b covering the gap between the rack 65b and the rack 65c are "compartment B". It is provided in ".

　このため、ラック６５ａ～６５ｃが離されて収納室３０に設置されている場合であっても、閉塞部材６９ａ，６９ｂを設けることにより、“区画Ｂ”と、ラック６５ａ～６５ｃとの隙間を覆うことができる。この結果、冷凍庫２５を用いた場合であっても“白煙”の発生を抑制できる。なお、閉塞部材６９ａ，６９ｂは、「第２閉塞部材」に相当する。 Therefore, even when the racks 65a to 65c are separated and installed in the storage chamber 30, the gap between the "section B" and the racks 65a to 65c is covered by providing the closing members 69a and 69b. be able to. As a result, the generation of "white smoke" can be suppressed even when the freezer 25 is used. The closing members 69a and 69b correspond to the "second closing member".

　図１５は、収納箱９５の構成を示す図である。図８の収納箱９０には、凹部９２が形成された蓋９１が取り付けられることにより、“流路Ｐ２”が形成された。収納箱９５では、左右方向における中央の列の容器８０が、他の容器８０より深く収納箱９５に差し込まれ、凹みが形成されることにより、“流路Ｐ２”と同様の“流路Ｐ３（第３流路）”が形成される。つまり、複数の容器８０は、引き出し部１００が引き出される際に、庫内の空気を、庫外へ流す“流路Ｐ３”を形成する。 << Other embodiments of the storage box >>
FIG. 15 is a diagram showing the configuration of the storage box 95. A "flow path P2" was formed in the storage box 90 of FIG. 8 by attaching a lid 91 having a recess 92 formed therein. In the storage box 95, the container 80 in the center row in the left-right direction is inserted into the storage box 95 deeper than the other containers 80, and a recess is formed, so that the “flow path P3 (flow path P3” similar to the “flow path P2” is formed. A third flow path) ”is formed. That is, the plurality of containers 80 form a "flow path P3" that allows the air inside the refrigerator to flow to the outside of the refrigerator when the drawer portion 100 is pulled out.

　このような収納箱９５を、蓋を取り付けずに引き出し部１００に収納すると、引き出し部１００の上側には、引き出し部１００の長手方向に沿った“流路Ｐ３”が形成されることになる。したがって、収納箱９５を用いる場合であっても、引き出し部１００を引き出す際には、早い速度で庫内の空気を放出することができる。 When such a storage box 95 is stored in the drawer portion 100 without attaching the lid, a "flow path P3" along the longitudinal direction of the drawer portion 100 is formed on the upper side of the drawer portion 100. Therefore, even when the storage box 95 is used, the air in the refrigerator can be discharged at a high speed when the drawer portion 100 is pulled out.

　なお、図１５は、収納箱９５の一例であり、複数の容器８０を用いて庫内の空気を流す流路ができれば、どのように容器８０を収納しても良い。 Note that FIG. 15 is an example of the storage box 95, and the container 80 may be stored in any way as long as a flow path for flowing air in the refrigerator is created by using a plurality of containers 80.

＝＝＝まとめ＝＝＝
　以上、本実施形態の冷凍システム１０について説明した。冷凍庫２０では、収納室３０が“区画Ａ”及び“区画Ｂ”の２つの区画を含むこととしたが、例えば、“区画Ａ”がなく、“区画Ｂ”のみの冷凍庫であっても良い。このような冷凍庫において、ラック６５と、“区画Ｂ”との“隙間Ｇ”は、閉塞部材６６～６８により覆われている。このため、例えば、ラック６５から引き出し部１００が引き出される際には、冷凍庫内の空気が、早い速度で庫外に流れでる。この結果、“区画Ｂ”のみの冷凍庫であっても、“白煙”の発生を抑制できる。 === Summary ===
The refrigeration system 10 of the present embodiment has been described above. In the freezer 20, the storage chamber 30 includes two compartments, "compartment A" and "compartment B". For example, a freezer without "compartment A" and only "compartment B" may be used. In such a freezer, the "gap G" between the rack 65 and the "compartment B" is covered with the closing members 66 to 68. Therefore, for example, when the drawer portion 100 is pulled out from the rack 65, the air in the freezer flows out of the freezer at a high speed. As a result, the generation of "white smoke" can be suppressed even in the freezer having only "compartment B".

　また、図１２に示したように、引き出し部１００が、例えばラック６５の最上段に収納されると、引き出し部１００の前面板１２４は、ラック６５の挿入口２５０ａは覆う。このような引き出し部１００を用いることにより、ラック６５に生じる隙間を小さくできる。このため、ラック６５から、引き出し部１００が引き出された際に、庫外に放出される空気の速度を、より上昇させることができる。 Further, as shown in FIG. 12, when the drawer portion 100 is housed in the uppermost stage of the rack 65, for example, the front plate 124 of the drawer portion 100 covers the insertion port 250a of the rack 65. By using such a drawer portion 100, the gap generated in the rack 65 can be reduced. Therefore, when the drawer portion 100 is pulled out from the rack 65, the speed of the air discharged to the outside of the refrigerator can be further increased.

　また、図１４に示す冷凍庫２５では、ラック６５ａ～６５ｃの間が離されて設置されている。このような冷凍庫２５であっても、ラック６５ａ～６５ｃの間に生じる隙間を、閉塞部材６９で覆うことにより、“区画Ｂ”の隙間を塞ぐことができる。この結果、ラック６５から、引き出し部１００が引き出された際に、庫外に放出される空気の速度を、上昇させることができる。 Further, in the freezer 25 shown in FIG. 14, the racks 65a to 65c are separated from each other. Even in such a freezer 25, the gap of the "section B" can be closed by covering the gap generated between the racks 65a to 65c with the closing member 69. As a result, when the drawer portion 100 is pulled out from the rack 65, the speed of the air discharged to the outside of the refrigerator can be increased.

　また、断熱扉５２が開かされた際、ラック６５の挿入口２５０を介し、収納室３０の空気がスムーズに外へ放出されるよう、ラック６５には、収納室３０の空気を取り込む開口２１０，２１１が形成されている。このため、ラック６５は、空気の取り込み口が形成されていない一般的なラックと比較すると、より早い速度で、収納室３０の空気を庫外に放出することができる。 Further, when the heat insulating door 52 is opened, the rack 65 has an opening 210 for taking in the air of the storage chamber 30 so that the air of the storage chamber 30 is smoothly discharged to the outside through the insertion port 250 of the rack 65. 211 is formed. Therefore, the rack 65 can discharge the air in the storage chamber 30 to the outside of the refrigerator at a faster speed than that of a general rack in which the air intake port is not formed.

　また、例えば図９に示したように、引き出し部１００の底面には、底板１５０，１５１と、底面板１２０の下側の面とで、庫内の空気を外へ流す“流路Ｐ１”が形成されている。このため、庫外に放出される空気の速度は上昇するため、効果的に“白煙”の発生を抑制できる。 Further, for example, as shown in FIG. 9, on the bottom surface of the drawer portion 100, there are "flow paths P1" through which the air in the refrigerator flows to the outside by the bottom plates 150 and 151 and the lower surface of the bottom plate 120. It is formed. Therefore, since the velocity of the air discharged to the outside of the refrigerator increases, the generation of "white smoke" can be effectively suppressed.

　また、例えば図８に示したように、収納箱９０の蓋９１には、引き出し部１００が引き出される際に、庫内の空気を外へ流す凹部９２により、“流路Ｐ２”が形成されている。このため、庫外に放出される空気の速度は上昇するため、より、確実に“白煙”の発生を抑制できる。 Further, for example, as shown in FIG. 8, in the lid 91 of the storage box 90, a “flow path P2” is formed by a recess 92 that allows air in the refrigerator to flow to the outside when the drawer portion 100 is pulled out. There is. Therefore, since the velocity of the air discharged to the outside of the refrigerator increases, the generation of "white smoke" can be suppressed more reliably.

　また、例えば図１５に示したように、収納箱９５は、“流路Ｐ３”が形成されるように、複数の容器８０を収納するため、例えば、収納箱９５には蓋を取り付ける必要がない。このため、利用者が、所望の容器８０を取り出す際の作業効率を上げることができる。 Further, for example, as shown in FIG. 15, since the storage box 95 stores a plurality of containers 80 so that the “flow path P3” is formed, for example, it is not necessary to attach a lid to the storage box 95. .. Therefore, the work efficiency when the user takes out the desired container 80 can be improved.

　また、収納室３０には、ラック６５が設けられた“区画Ｂ”以外に、他のラック（不図示）等を収納できる“区画Ａ”が設けられている。しかしながら、“区画Ａ”には、開口５３ａを覆う内扉６３，６４が設けられてため、内扉６３，６４が覆われている状態では、“区画Ａ”、“区画Ｂ”には、隙間は塞がれている。したがって、本実施形態のように、２つ“区画”がある場合であっても、“白煙”の発生を抑制することができる。 Further, in the storage chamber 30, in addition to the "section B" in which the rack 65 is provided, a "section A" in which other racks (not shown) and the like can be stored is provided. However, since the inner doors 63 and 64 that cover the opening 53a are provided in the "section A", there are gaps in the "section A" and the "section B" when the inner doors 63 and 64 are covered. Is blocked. Therefore, even when there are two "compartments" as in the present embodiment, the generation of "white smoke" can be suppressed.

　また、収納室３０で冷やされた空気の密度は高くなる。このため、２つの区画の下側の“区画Ｂ”にラック６５等を設ける方が、“区画Ａ”にラック６５等を設けるより、引き出し部１００が引き出された場合に放出される空気の速度を上昇させることができる。この結果、底面側の“区画Ｂ”にラック６５を設置することにより、効果的に“白煙”の発生を抑制できる。 Also, the density of air cooled in the storage room 30 becomes high. Therefore, it is better to provide the rack 65 or the like in the lower "section B" of the two sections than to provide the rack 65 or the like in the "section A", and to release the air when the drawer portion 100 is pulled out. Can be raised. As a result, the generation of "white smoke" can be effectively suppressed by installing the rack 65 in the "section B" on the bottom surface side.

　また、“区画Ｂ”には、ラック６５に収納された容器８０の無線タグ８５の情報を取得するアンテナ４００が設けられている。このため、利用者は、例えば、冷凍庫２０の断熱扉５２を開ける前の状態にて、所望の容器の位置を把握できる。したがって、利用者は、断熱扉５２を開放し、所望の容器のみを取り出すことができるため、検体の劣化を防ぐことができる。 Further, in the "section B", an antenna 400 for acquiring the information of the wireless tag 85 of the container 80 housed in the rack 65 is provided. Therefore, the user can grasp the position of the desired container, for example, in the state before opening the heat insulating door 52 of the freezer 20. Therefore, since the user can open the heat insulating door 52 and take out only the desired container, deterioration of the sample can be prevented.

　上記の実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。また、本発明は、その趣旨を逸脱することなく、変更や改良され得るとともに、本発明にはその等価物が含まれるのはいうまでもない。例えば、以下に示すような変形が可能である。 The above embodiment is for facilitating the understanding of the present invention, and is not for limiting and interpreting the present invention.
