Abstract

PROBLEM TO BE SOLVED: To add a structure having a high cold air flow-out suppression effect without impairing its purpose, and to obtain a high power saving effect, mainly in an inexpensive household versatile electric refrigerator.SOLUTION: A body 100 has a cold air flow-in port 101 using, at its main part, polymethylmethacrylate having high transparency, a polycarbonate resin (organic glass) or the like, and a cold air flow-out port 102. When a user lifts up a front face door 108, the front face door 108 and a shutter 104 become horizontal by the action of a movable joint 109, and when a shutter draw-in spring 106 is contracted and draws in the shutter 104 and the front face door 108, and when refrigeration articles become possible to be drawn in/from the body 100, the shutter 104 closes the cold air flow-in port 101 and the cold air flow-out port 102, and immediately stops the flow-out of cold air from the inside of the refrigerator.

Description

本発明は、冷蔵庫扉を開けた際にも冷気流出を有効に阻止して内蔵する冷蔵物品を可能な限り保冷状態に保つ器具に関する。   The present invention relates to a device that effectively prevents cold air outflow and keeps a built-in refrigerated article as cool as possible even when a refrigerator door is opened.

エネルギー資源の枯渇が現実の問題となっている今日、電気エネルギーの使用削減は至上命題である。
電気エネルギーの使用削減、すなわち消費電力削減はこれを用いる個々の電気機器の使用を止めることによって直ちに成し得ることができるものではあるが、一方でその使用を止めることが困難なものについては、エネルギー保存の法則により、個々電気機器でのエネルギー変換損失を減ずるなどの手段方法を講じる以外にない。 In today's world where depletion of energy resources is a real problem, reducing the use of electrical energy is a critical issue.
The reduction in the use of electric energy, that is, the reduction in power consumption, can be achieved immediately by stopping the use of the individual electrical equipment that uses it, but on the other hand it is difficult to stop the use. There is no other way but to take measures such as reducing the energy conversion loss in individual electrical devices according to the law of conservation of energy.

特に今日、広く一般家庭に普及した電気冷蔵庫においては、他により有効な代替手段を見出すことが困難であって、その使用を止めることの難しい消費電力削減は無視する事が出来ない。   Especially in today's electric refrigerators that are widely used in ordinary households, it is difficult to find other effective alternative means, and the power consumption reduction that is difficult to stop using cannot be ignored.

電気冷蔵庫での消費電力損失を減ずるには、一度冷却した庫内空気（冷気）の流出を防ぐことが効果的である。このため従来、産業用大型電気冷蔵庫、即ち冷蔵倉庫等では全体を密閉構造とした上で二重扉化、即ち有人宇宙船に用いられるエアロックと同様にその出入口部分（物品搬入口部分）に必要最小容積の別室を設け、一度ここに全ての冷蔵物品を搬入した後、外側の扉を閉め、しかる後に内側の冷蔵倉庫扉を開けて冷蔵物品を搬入、冷気流出を最小限に止めるという方法が広く用いられている。   In order to reduce the power consumption loss in the electric refrigerator, it is effective to prevent the inside air (cold air) that has been cooled once from flowing out. For this reason, conventionally, large industrial electric refrigerators, that is, refrigerated warehouses, etc., have a closed structure and are double-doored, that is, in the entrance part (article carry-in part) like an air lock used in a manned spacecraft. A method of providing a separate room with the required minimum volume, once all the refrigerated goods are brought in here, closing the outer door, then opening the inner refrigerated warehouse door to carry in the refrigerated goods and minimizing the outflow of cold air Is widely used.

しかしながら、産業用冷蔵倉庫等の個数は全電気冷蔵庫数に対してはごく僅かであり、特に最も数多い一般家庭用電気冷蔵庫や商店の商品陳列型電気冷蔵庫を上述従来の二重扉構造とすることは冷却効率の維持と省エネルギーの見地から困難である。そのため全電気冷蔵庫での冷気流出阻止による消費電力削減はなかなか成し得ていないのが現状である。 However, the number of industrial refrigerated warehouses is very small compared to the total number of electric refrigerators. Especially, the most common household electric refrigerators and merchandise display type electric refrigerators have the above-mentioned conventional double door structure. It is difficult to maintain cooling efficiency and save energy. Therefore, the current situation is that power consumption has not been reduced by preventing the outflow of cold air in all electric refrigerators.

この現状は、これらの家庭用電気冷蔵庫の使用目的が大型の産業用冷蔵倉庫等とは根本的に異なる事による。 This is because the purpose of use of these household electric refrigerators is fundamentally different from that of large industrial refrigerated warehouses.

家庭用電気冷蔵庫では、保冷中の多種多様な冷蔵物品を簡単に視認してから冷蔵庫内から取り出すこと、また冷蔵物品の出し入れを頻繁かつ容易に行い得ることが求められる。即ち一部冷蔵部を除いて上述従来の二重扉構造とすることが必然的に内蔵物の視認とアクセスに甚だ不便なものとなるからである。 In an electric refrigerator for home use, it is required that a wide variety of refrigerated articles being kept cold can be easily viewed and then taken out from the refrigerator, and that the refrigerated articles can be taken in and out frequently. In other words, the above-described conventional double door structure except for a part of the refrigeration part is inevitably inconvenient for visual recognition and access to the built-in objects.

特にこれは内蔵する食品や飲料等を出し入れする機会の多い家庭用電気冷蔵庫において顕著であり、従来、電気冷蔵庫扉内側に透明な塩化ビニル樹脂製シート等を設置して冷気流出を抑える、あるいは冷凍、冷蔵室を小分けにして独立させ、それぞれ密閉して冷気流出を抑えるといった方法が数多く考案され、実用に供されてきたが、適切なモデルはなお定まっていない。 This is especially noticeable in household electric refrigerators where there are many opportunities to put in and out foods and beverages built in. Conventionally, a transparent vinyl chloride resin sheet, etc. has been installed inside the electric refrigerator door to prevent cold air from flowing out or freezing. Many methods have been devised and put into practical use, such as subdividing the refrigeration room into independent parts and sealing them to suppress the outflow of cold air, but an appropriate model has not yet been determined.

しかしながら、例えば冷蔵室扉の内側に更に透明な合成樹脂シートで成るドア等を設置して冷気流失を防ぐ方法では、冷蔵物品の視認中はよいが、その取り出し時には多くの冷気が流出してしまい、内外ドアの開閉毎に室温空気が庫内の冷気と入れ換わり電気冷蔵庫内の温度が急激に上昇する事態を避けられない問題がある。 However, for example, a method of installing a door made of a transparent synthetic resin sheet or the like inside the refrigerator compartment door to prevent the loss of the cold air flow is good while the refrigerated article is visually recognized, but a lot of cold air flows out when the refrigerator is taken out. There is an unavoidable problem that room temperature air is replaced with cool air in the cabinet every time the inner and outer doors are opened and closed, and the temperature in the electric refrigerator rapidly rises.

また冷蔵室を小分けにして独立させ、それぞれ密閉して、冷気流出を抑える方法では、確かに冷気流出はその部分だけで最小限に抑えられるものの、冷蔵物品の視認性が悪く、また構造も所謂衣類箪笥の引き出しのようになり複雑化する。その結果、箪笥に衣類を整理収容するのと同様に、冷蔵物品を瞬時に視認選別して取り出し、冷気流出を最小限とするためには、各冷蔵室扉に収容している冷蔵物品名を予め記載しておく必要があるといった不便を生じる。 In addition, in the method in which the refrigeration room is divided into small parts, and each is sealed to suppress the cold air outflow, the cold air outflow is surely minimized only in that part, but the visibility of the refrigerated article is poor and the structure is also so-called. It becomes complicated like a drawer for clothes. As a result, in the same way as arranging and storing clothes in the bag, in order to instantly visually select and take out the refrigerated items and minimize the outflow of cold air, the name of the refrigerated items accommodated in each refrigeration room door can be changed. Inconvenience that it is necessary to describe in advance.

また、家庭用電気冷蔵庫の冷蔵室を小分けして密閉することは、その分構造が複雑化してコストアップし、さらには冷気の流通を妨げることにもなるため、必ずしも好ましいものではない。 Further, it is not always preferable to divide and seal the refrigerator compartment of a household electric refrigerator because the structure becomes complicated and the cost is increased, and further, the flow of cold air is hindered.

衣類箪笥等では各抽き出しを透明な合成樹脂等で作り、収容している衣類について抽き出しを開けなくても視認できるようにすることができるが、冷蔵庫に内蔵する冷蔵物品ではその種類も多く、当然、その色彩や形態も変動するため簡単ではない。 For clothes baskets, etc., each drawer can be made of transparent synthetic resin, etc., so that it can be seen without opening the drawer for the clothes it contains. Of course, it is not easy because its color and form change.

これはまた、例えば冷蔵室の扉を透明、即ち冷蔵物品を視認するために必要な可視光領域の光を透過させるようにすると、可視光領域に近接する熱線、即ち冷蔵庫内の温度を直接上昇させる赤外線の侵入を許すようになるためでもある。
またこの場合、可視光領域に近接する化学線、即ち紫外線や柔Ｘ線の侵入も許し、例えば風味を保つため、有用菌類を殺菌していない暗所保存を要求する食品、即ち高温のみならず光による影響をも嫌うことの多い冷蔵物品を長期安定保存する冷蔵庫の根本目的を阻害することになる。過去、赤外線から概ね柔Ｘ線までのおよそ冷蔵物品に影響を与える光を高度に遮蔽する目的より、その冷蔵室本体から前扉まで主要部を鉛で構成した家庭用電気冷蔵庫が実用化、市販されていた。今日においても赤外線、紫外線また概ね柔Ｘ線を遮蔽し、可視光領域の光のみを透過させるためには特別な光学遮蔽フィルタが必要であるから、もとより廉価を求められる家庭用電気冷蔵庫には不向きで、実用例は皆無に等しい。 For example, if the door of the refrigerator compartment is transparent, that is, the light in the visible light region necessary for visually recognizing the refrigerated article is transmitted, the heat ray close to the visible light region, that is, the temperature in the refrigerator is directly increased. This is also to allow the intrusion of infrared rays.
Also, in this case, invasion of actinic rays close to the visible light region, that is, ultraviolet rays and soft X-rays, is allowed, for example, foods that require preservation in the dark without sterilizing useful fungi in order to maintain the flavor, that is, not only high temperatures. This obstructs the basic purpose of refrigerators that stably store refrigerated goods that are often disliked by light. In the past, for the purpose of highly shielding light that affects refrigerated goods from infrared rays to generally soft X-rays, domestic electric refrigerators that consist of lead from the refrigerator compartment body to the front door have been put into practical use and are commercially available. It had been. Even today, a special optical shielding filter is necessary to shield infrared rays, ultraviolet rays, and generally soft X-rays, and transmit only light in the visible light range, so it is not suitable for home electric refrigerators that are required to be inexpensive. There are no practical examples.

一部の業務用冷蔵庫には家庭用電気冷蔵庫を改造し、一つの冷蔵室内を棚および透明な前面蓋によって小分けして商品を陳列、商品購入者は冷蔵庫の前扉を開けて商品を視認選択、選択した商品の代金を支払った後に当該商品棚の透明な前面蓋を開けて商品を取り出す構造とされているもの等もあるが、これは所謂自動販売機であり、冷蔵室内への棚及び透明な前面蓋の設置の目的は冷気流出阻止による冷却効率の維持と省エネルギーではなく、特定された商品である冷蔵物品の陳列およびその盗難防止にある。従ってもとより不特定多様な冷蔵物品の収容を要求される家庭用電気冷蔵庫の構造には適さない。これらの課題を解決することが本発明の目的である。 Some commercial refrigerators have been modified from household electric refrigerators, and one refrigerated room is subdivided by shelves and transparent front lids to display products, and product buyers can open the front door of the refrigerator and select the products visually In some cases, after paying the price of the selected product, the product shelf is opened to take out the product by opening the transparent front lid of the product shelf, which is a so-called vending machine, The purpose of installing the transparent front cover is not to maintain cooling efficiency and prevent energy saving by preventing the outflow of cold air, but to display the refrigerated goods, which are specified products, and prevent theft. Therefore, it is not suitable for the structure of an electric refrigerator for homes that is required to accommodate various kinds of refrigerated goods. It is an object of the present invention to solve these problems.

そこで本発明者は最も効率の良い、即ち根本解決策ともいえる従来からの産業用冷蔵倉庫の二重扉方式をヒントにして工夫研究を続けた結果、冷蔵庫内の棚部分に装着するだけで汎用の家庭用電気冷蔵庫を簡単に二重扉方式の省電力効果の高い電気冷蔵庫にすることのできる本発明に到達した。   Therefore, the present inventor has continued research on the idea of the double door system of the conventional industrial refrigerated warehouse, which is the most efficient, that is, the fundamental solution. The present invention has reached the present invention, which can easily make a double-door electric refrigerator with high power-saving effect.

本発明による家庭用電気冷蔵庫は、標準化された三元サイズの基本的に長方形型の庫内出し入れと開蓋性に優れた内容物透視可能で透明な合成樹脂製の蓋付き冷気遮断型ユニット容器を複数個冷蔵庫内に複数段の抽出し状に整列配置し、多数冷蔵物品の整頓収納と内容物の識別性に優れた事を特徴とする。   The electric refrigerator for home use according to the present invention is a standard ternary size, basically rectangular-shaped storage and storage unit with a lid made of transparent synthetic resin that can be seen through and is transparent in contents with excellent openability. A plurality of items are extracted and arranged in a plurality of stages in a refrigerator, and are characterized by an excellent storage of a large number of refrigerated articles and an excellent identification of contents.

また本発明による家庭用電気冷蔵庫は、前記蓋付き冷気遮断ユニット型容器の蓋が閉止時に容器フランジに弾性的にクリックストップする係止具で該フランジの一方に片手の指先で開放可能であり利用者の片手操作で容易に開放閉止するようにした事を特徴とする。
また本発明による家庭用電気冷蔵庫は、前記合成樹脂製の蓋付き冷気遮断型ユニット容器の蓋が、該容器を冷蔵庫外に取り出した時に利用者の片手の指先で容易に止着部を開放して開蓋し得るようにした事を特徴とする。 The household electric refrigerator according to the present invention can be opened with a fingertip of one hand on one side of the flange with a locking tool that elastically clicks and stops on the container flange when the lid of the cold air shutoff unit type container with the lid is closed. It is characterized in that it can be easily opened and closed by one hand operation of the person.
In addition, in the electric refrigerator for home use according to the present invention, the lid of the cold-insulated unit container with a lid made of synthetic resin easily opens the fastening portion with the fingertip of one hand of the user when the container is taken out of the refrigerator. It is characterized in that it can be opened.

本発明によれば、産業用冷蔵倉庫等に近い冷気流出抑制効果を持つ、内容物の視認性に優れた省電力型の家庭用電気冷蔵庫が提供される。   ADVANTAGE OF THE INVENTION According to this invention, the electric power saving type | mold household electric refrigerator excellent in the visibility of the content which has the cool air outflow suppression effect near an industrial refrigerated warehouse etc. is provided.

以下、図面を参照して本発明を説明する。   The present invention will be described below with reference to the drawings.

図１は本発明の冷気遮断型ユニット容器の実施例を示す一部透視斜視図である。１００は抽出状収納箱本体、１０１は冷気流入口、１０２は冷気流出口、１０３は棚板、１０４はシャッター、１０５はシャッターレール、１０６はシャッター引き込み用コイルバネ、１０７は冷気漏止パッキング、１０８は前面扉、１０９は可動継手、１１０は前面扉開閉取手、１１１は前面扉係止具である。 FIG. 1 is a partially transparent perspective view showing an embodiment of a cold air blocking type unit container of the present invention. 100 is an extraction storage box body, 101 is a cold air inlet, 102 is a cold air outlet, 103 is a shelf board, 104 is a shutter, 105 is a shutter rail, 106 is a coil spring for retracting a shutter, 107 is a cold air leakage packing, and 108 is A front door, 109 is a movable joint, 110 is a front door opening / closing handle, and 111 is a front door lock.

シャッター１０４とシャッター引き込み用コイルバネ１０６はシャッターレール１０５内で結合されており、前面扉１０８を閉じた状態では伸張した状態にある。このときシャッター１０４と前面扉１０８を結合している可動継手１０９の作用により、前面扉１０８とシャッター１０４は直角となっておりシャッター引き込み用コイルバネ１０６は伸張したまま動かない。このとき冷気流入口１０１および冷気流出口１０２は開状態にある。 The shutter 104 and the shutter pull-in coil spring 106 are coupled in the shutter rail 105, and are in an extended state when the front door 108 is closed. At this time, due to the action of the movable joint 109 connecting the shutter 104 and the front door 108, the front door 108 and the shutter 104 are at right angles, and the coil spring 106 for retracting the shutter does not move while being stretched. At this time, the cold air flow inlet 101 and the cold air flow outlet 102 are in an open state.

図２および図３は本発明の冷気遮断型ユニット容器の実施例の開蓋動作を示す一部透視斜視図である。図２において利用者が前面扉開閉取手１１０を片手の指先で抓み、小さな永久磁石と鉄片の組み合わせによって構成された前面扉係止具１１１のごく弱い係止力に抗して前面扉１０８を図２に記載の矢印で示すように軽く上方に引き上げると、可動継手１０９の作用により前面扉１０８とシャッター１０４は水平となり、シャッター引き込み用コイルバネ１０６は収縮、図３に記載の矢印で示す方向にシャッター１０４と前面扉１０８を引き込み、抽出状収納箱本体１００への冷蔵物品の出し入れが可能となる。 2 and 3 are partially perspective perspective views showing the opening operation of the embodiment of the cold air blocking type unit container of the present invention. In FIG. 2, the user squeezes the front door opening / closing handle 110 with the fingertip of one hand, and moves the front door 108 against the very weak locking force of the front door locking tool 111 composed of a combination of a small permanent magnet and an iron piece. When it is lifted lightly upward as indicated by the arrow shown in FIG. 2, the front door 108 and the shutter 104 become horizontal by the action of the movable joint 109, and the shutter pull-in coil spring 106 contracts, in the direction indicated by the arrow shown in FIG. The shutter 104 and the front door 108 are pulled in, and the refrigerated article can be taken in and out of the extraction-like storage box body 100.

このときシャッター１０４は図３に記載の矢印で示す方向にスライドして冷気流入口１０１を閉じ、冷蔵庫内からの冷気流出を止める。利用者が抽出状収納箱本体１００への冷蔵物品の出し入れを終了し、前面扉１０８の前面扉開閉取手１１０を片手の指先で抓み、可動継手１０９が図１および図２に示す位置にくるまで前面扉１０８を手前に引いて前面扉開閉取手１１０より指を離すと、前面扉１０８はその自重により自然に閉まり、シャッター１０４は冷気流入口１０１を空け、再び抽出状収納箱本体１００内に冷気が流入し、抽出状収納箱本体１００中に収容されている冷蔵物品は再び冷蔵状態になる。 At this time, the shutter 104 slides in the direction indicated by the arrow in FIG. 3 to close the cold air inlet 101 and stop the cold air from flowing out of the refrigerator. The user finishes putting refrigerated goods into and out of the extractable storage box main body 100, holds the front door opening / closing handle 110 of the front door 108 with the fingertip of one hand, and the movable joint 109 is in the position shown in FIGS. When the front door 108 is pulled to the front and the finger is released from the front door opening / closing handle 110, the front door 108 is naturally closed by its own weight, and the shutter 104 opens the cold air flow inlet 101, and again enters the extractable storage box body 100. Cold air flows in, and the refrigerated article accommodated in the extractable storage box body 100 is refrigerated again.

なお図１、図２および図３では説明のため、冷気流出口１０２側、すなわち本体側面のシャッター表記を省略したものとしているが、シャッター１０４は所謂コの字型断面構造となっており、シャッター１０４は冷気流入口１０１を閉じたときには併せて冷気流出口１０２も閉じる。 1, 2, and 3, the shutter notation on the cold air outlet 102 side, that is, the side surface of the main body is omitted for the sake of explanation, but the shutter 104 has a so-called U-shaped cross-sectional structure. When the cold air inlet 101 is closed, the cold air outlet 102 is also closed.

また、利用者が抽出状収納箱本体１００への冷蔵物品の出し入れを終了し、前面扉１０８の前面扉開閉取手１１０を片手の指先で抓み、可動継手１０９が図１及び図２に示す位置にくるまで前面扉１０８を手前に十分に引き切らずに前面扉開閉取手１１０より指を離した場合、シャッター引き込み用コイルバネ１０６は再び直ちに収縮、図３に記載の矢印で示す方向にシャッター１０４と前面扉１０８を再び引き込み、冷気流入口１０１および冷気流出口１０２を再び閉じ、冷気流入口１０１および冷気流出口１０２の不完全な開状態を阻止して抽出状収納箱本体１００を経由しての冷蔵庫外への不測の連続冷気流出を阻止するとともに、利用者に前面扉１０８を正しく閉じる事を促し、抽出状収納箱本体１００中に収容されている冷蔵物品のより確かな冷蔵を実現する。 Further, the user finishes putting in and out the refrigerated article into the extraction storage box main body 100, holds the front door opening / closing handle 110 of the front door 108 with the fingertip of one hand, and the movable joint 109 is positioned as shown in FIGS. When the finger is released from the front door opening / closing handle 110 without fully pulling the front door 108 forward until it comes to, the shutter pulling coil spring 106 immediately contracts again, and the shutter 104 and the shutter 104 in the direction indicated by the arrow in FIG. The front door 108 is pulled in again, the cold air flow inlet 101 and the cold air flow outlet 102 are closed again, and an incomplete open state of the cold air flow inlet 101 and the cold air flow outlet 102 is prevented to pass through the extractive storage box body 100. Refrigerated goods housed in the extractive storage box body 100 while preventing unexpected continuous cold air outflow to the outside of the refrigerator and encouraging the user to close the front door 108 correctly. To achieve a more reliable refrigeration.

家庭用冷蔵庫内の冷気は通常、冷蔵庫上部から下部に流れる構造となっているため、その流れを妨げないように冷気流入口１０１は抽出状収納箱本体１００の上面、冷気流出口１０２は抽出状収納箱本体１００の側面に設けるのが原則であるが、その詳細な位置、形状、大きさ等については特に限定されない。
抽出状収納箱本体１００は棚板１０３に載せて使用するが、この棚板は特に専用のものとする必要はなく、むしろ汎用冷蔵庫に標準で付属している棚板を積極的に利用するのが望ましい。 Since the cold air in the home refrigerator normally has a structure that flows from the upper part to the lower part of the refrigerator, the cold air inlet 101 is the upper surface of the extractable storage box body 100 and the cold air outlet 102 is the extracted one so as not to disturb the flow. Although it is a principle to provide in the side surface of the storage box main body 100, the detailed position, shape, size, etc. are not specifically limited.
The extractable storage box main body 100 is used by being placed on the shelf board 103, but this shelf board does not need to be specially used. Rather, the shelf board that comes standard with a general-purpose refrigerator is actively used. Is desirable.

しかしこのため、抽出状収納箱本体１００と冷蔵庫内面との間に隙間ができ、ここからの冷気漏れが生じることから、冷気漏止パッキング１０７によってその隙間を塞ぎ、より確実に冷気漏れを防ぐようにする。 However, a gap is formed between the extractable storage box main body 100 and the refrigerator inner surface, and cold air leaks from the gap. Therefore, the cold air leakage packing 107 closes the gap so as to prevent the cold air leakage more reliably. To.

これにより抽出状収納箱本体１００を、その中に冷蔵物品を内蔵したまま冷蔵庫本体より、もとより脱着簡単な汎用冷蔵庫に標準で付属している棚板ごと簡単に取り出すことを可能とし、冷蔵庫本体内の清掃等を容易なものとする。このとき冷気流入口１０１、冷気流出口１０２は閉じたままであるので、当該抽出状収納箱本体に内蔵された冷蔵物品は暫くの間、保冷されている。 As a result, the extractable storage box main body 100 can be easily taken out from the refrigerator main body with the shelf attached to the general-purpose refrigerator that is easy to detach as a standard from the refrigerator main body with the refrigerated article incorporated therein. It will be easy to clean. At this time, since the cold air flow inlet 101 and the cold air flow outlet 102 remain closed, the refrigerated article incorporated in the extracted storage box body is kept cold for a while.

さらに抽出状収納箱本体１００は独立した収容箱であることから、例えば冷蔵庫外に収納箱本体を取り出し、前面扉１０８を利用者の片手の指先で容易に開け、素早く内蔵の冷蔵物品を全て取り出して収容箱全体あるいは一部を清掃、再び冷蔵物品を素早く収容箱内に収容して冷蔵庫本体内に戻すことも出来る。 Further, since the extracted storage box body 100 is an independent storage box, for example, the storage box body is taken out of the refrigerator, the front door 108 is easily opened with the fingertip of one hand of the user, and all the built-in refrigerated articles are quickly taken out. The entire or a part of the storage box can be cleaned, and the refrigerated article can be quickly stored in the storage box and returned to the refrigerator body.

概ね廉価な家庭用冷蔵庫の本体内清掃は、冷蔵機能を全て停止した後、冷蔵物品全てを取り出してから行う必要があるが、即ち本発明を既存の家庭用冷蔵庫に付加するだけで、対象となる部分のみについて清掃すればよくなり、冷蔵機能の全てを清掃のために停止する必要も無くなる。 Cleaning the inside of the main body of a generally inexpensive refrigerator needs to be performed after all the refrigerated items are taken out after stopping the refrigeration function, that is, only by adding the present invention to an existing household refrigerator. It is only necessary to clean the part, and it is not necessary to stop all the refrigeration functions for cleaning.

従って冷蔵物品への影響も最小限に抑えることが出来る。 Therefore, the influence on refrigerated articles can be minimized.

なお前面扉係止具１１１は、前面扉１０８が可動継手１０９および重力の作用によって閉止するため、前面扉１０８の止着機能上は本来不要のものであるが、例えば利用者が抽出状収納箱本体１００にその奥行きをわずかに超える長物の冷蔵物品を収容し、前面扉１０８が不完全に閉止する事態に至った際、利用者に前面扉１０８の閉止時の所謂、音の違い等によってそれを認識させることに役立つことから設けることが望ましい。 Since the front door 108 is closed by the action of the movable joint 109 and gravity, the front door locking tool 111 is originally unnecessary for the fastening function of the front door 108. When a refrigerated article slightly longer than the depth is accommodated in the main body 100 and the front door 108 is incompletely closed, the user is informed by the so-called difference in sound when the front door 108 is closed. It is desirable to provide this because it helps to recognize

即ち前面扉係止具１１１は特に限定されず、本実施例の様に、小さな永久磁石と鉄片の組み合わせによって構成されたものであってもよいし、より確実、積極的に前面扉１０８の開閉状態を利用者に認識させるため、磁気あるいは光学接触センサ等と機械的に組み合わせ、概ね電気的に得られるその状態出力をランプやブザー等に伝達、前面扉１０８の開閉状態をランプの点滅表示あるいはブザーの鳴動によって利用者に認識させるものとしてもよい。 That is, the front door locking device 111 is not particularly limited, and may be configured by a combination of a small permanent magnet and an iron piece as in this embodiment, or more reliably and positively opening and closing the front door 108. In order to make the user recognize the state, it is mechanically combined with a magnetic or optical contact sensor, etc., and the state output obtained approximately electrically is transmitted to a lamp, a buzzer, etc. It is good also as what makes a user recognize by the sound of a buzzer.

抽出状収納箱本体１００はその主要部、即ち前面扉１０８をはじめとする各壁面に高透明度を有するポリメタクリル酸メチル、ポリカーボネート樹脂（有機ガラス）等を用い、抽出状収納箱本体１００中の冷蔵物品が利用者に明確にわかるようにする。 The extractable storage box main body 100 uses polymethyl methacrylate, polycarbonate resin (organic glass) or the like having high transparency on its main part, that is, each wall surface including the front door 108, and the refrigerator in the extractable storage box main body 100 is refrigerated. Make the article clear to the user.

これにより利用者は抽出状収納箱本体１００を複数、冷蔵庫内に設けた場合でも迷うことなく冷蔵物品を取り出すことが出来る。 Thus, the user can take out the refrigerated article without hesitation even when a plurality of the extracted storage box bodies 100 are provided in the refrigerator.

図４は本発明による家庭用電気冷蔵庫の開扉状態を示す正面である。４００は２ドア式冷凍冷蔵庫本体、４０１は冷蔵庫前面扉、４０２は冷凍庫前面扉である。 FIG. 4 is a front view showing an opened state of the household electric refrigerator according to the present invention.

図４に示すように、例えば廉価な汎用２ドア式冷凍冷蔵庫内の棚板空間の大きさに合わせて製作した抽出状収納箱本体１００を全ての棚に配置すると、冷蔵室前面扉４０１、冷凍室前面扉４０２の両方を全開状態にしても汎用２ドア式冷凍冷蔵庫４００内の冷気漏れを最小に抑えることができる。すなわち冷蔵庫前面扉４０１および冷凍庫前面扉４０２内側の所謂、ポケットなどに貯蔵してある冷凍、冷蔵物品以外への影響を低く抑えることができ、冷凍、冷蔵物品の視認、選択、取り出しのために暫くの間、冷蔵庫前面扉４０１、冷凍庫前面扉４０２の両方を全開状態にしてもかまわない。 As shown in FIG. 4, for example, when the extractable storage box bodies 100 manufactured according to the size of the shelf space in an inexpensive general-purpose two-door refrigerator are arranged on all the shelves, the refrigerator compartment front door 401, the freezer Even if both of the room front doors 402 are fully opened, the leakage of cold air in the general-purpose two-door refrigerator-freezer 400 can be minimized. That is, it is possible to suppress the influence on the parts other than the refrigeration and refrigeration articles stored in the so-called pockets inside the refrigerator front door 401 and the freezer front door 402, and for a while for visualizing, selecting, and taking out the refrigeration and refrigeration articles. During this time, both the refrigerator front door 401 and the freezer front door 402 may be fully opened.

すなわちこれは産業用冷蔵倉庫等と同様の二重扉構造の高い冷気流出抑制効果を持つ冷蔵庫であり本発明を付加するだけで廉価な家庭用電気冷蔵庫でも高い省電力効果が得られる。 In other words, this is a refrigerator having a high cold air outflow suppression effect similar to that of an industrial refrigerated warehouse or the like, and a high power saving effect can be obtained even with an inexpensive domestic electric refrigerator only by adding the present invention.

またそれゆえに家庭用電気冷蔵庫のみならず、例えば最低限、前面扉１０８の開閉状態をランプの点滅表示あるいはブザーの鳴動によって店舗運用者に遠隔通知させるようにするだけで、特に小規模有人店舗などでの商品陳列型電気冷蔵庫に適したものになる。 Therefore, not only electric refrigerators for home use, but also, for example, at least, it is possible to remotely notify the store operator of the open / closed state of the front door 108 by flashing a lamp or sounding a buzzer. Suitable for product display type electric refrigerators.

即ち商品購入者が頻繁に冷蔵庫の前面扉を全開にしても、冷蔵商品への影響が少なく、商品購入者は整理整頓された冷蔵商品をゆっくり選択できる。また通常使用において冷蔵庫内の清掃のために冷蔵機能の全てを停止する必要も無くなることから、店舗運営者側の大幅な省労力化も期待することができる。 That is, even if the product purchaser frequently opens the front door of the refrigerator, there is little influence on the refrigerated product, and the product purchaser can slowly select the refrigerated product that is organized. In addition, since it is not necessary to stop all the refrigeration functions for cleaning the refrigerator in normal use, significant labor savings can be expected on the store operator side.

なお上述の通り所謂、冷凍と冷蔵はその温度の違いによるだけに過ぎず、本発明の冷気遮断型ユニット容器は冷凍庫にも適用できることはいうまでもない。 As described above, the so-called refrigeration and refrigeration are only due to the difference in temperature, and it goes without saying that the cold air shutoff unit container of the present invention can also be applied to a freezer.

また冷蔵庫の設計段階より本発明を用いるならば、より精密で高い冷気流出抑制効果を期待することが出来る。 Further, if the present invention is used from the design stage of the refrigerator, it is possible to expect a more precise and high cooling outflow suppression effect.

家庭用をはじめとする汎用冷蔵庫全般に広く適用可能である。 It can be widely applied to general-purpose refrigerators including home use.
