Reference numerals 5 to 10 are connecting pipes. FIG. 4 is a configuration diagram showing another conventional nitrogen enriching device for a refrigerator, which is a simplified version of the conventional example shown in FIG. 3, and the same reference numerals as those in FIG. 3 denote the same or corresponding parts, and detailed description thereof will be given. Is omitted.
【0003】 次に図4に関する動作について説明する。密閉容器1内に設置した第1ガス分 離装置2及び第2ガス分離装置3は接続管5、10を介して減圧ポンプ4aに接 続されており、この減圧ポンプ4aを作動させることで、低圧室2c、3cは低 圧になり、高圧室2b、3bはそれぞれ高圧となる。ここで、上記分離膜2a、 3aは両面に圧力差が生じ、空気がガス分離膜2a、3aを高圧室2bから低圧 室2cへ、また高圧室3bから低圧室3cへと通過する。そして、このガス分離 膜2a、3aは、窒素に比べて酸素や炭酸ガス及び水を多く、すなわち早く透過 させるもので、例えば窒素のガス通過スピードを1とすれば、酸素は約2.2倍 、炭酸ガスは約8倍、水分は約22倍である。Next, the operation relating to FIG. 4 will be described. The first gas separation device 2 and the second gas separation device 3 installed in the closed container 1 are connected to the decompression pump 4a via the connecting pipes 5 and 10. By operating the decompression pump 4a, The low pressure chambers 2c and 3c have a low pressure, and the high pressure chambers 2b and 3b have a high pressure. Here, a pressure difference is generated on both sides of the separation membranes 2a and 3a, and air passes through the gas separation membranes 2a and 3a from the high pressure chamber 2b to the low pressure chamber 2c and from the high pressure chamber 3b to the low pressure chamber 3c. The gas separation membranes 2a, 3a allow more oxygen, carbon dioxide and water to permeate than nitrogen, that is, permeate faster. For example, if the gas passage speed of nitrogen is 1, the oxygen content is about 2.2 times. , Carbon dioxide is about 8 times, and water is about 22 times.
【0004】 その際のガスの通過スピードの差により、第1ガス分離装置2は減圧ポンプ4 aによって高圧室2b、低圧室2cに圧力差を生じ、高圧室2b側は窒素富化し 、低圧室2c側は酸素、炭酸ガス、水分富化の雰囲気となり密閉容器1内は減圧 、除湿されながら窒素富化される。又、第2ガス分離装置3も同様の働きで高圧 室3b側を窒素富化及び除湿する。そして、減圧ポンプ4aにより容器1より引 き出された空気を補うため、押込ポンプ4dから空気が押込まれて、高圧室3b で窒素富化し、かつ除湿された空気が接続管9を介し容器1内に供給され、この 窒素富化及び除湿された雰囲気を供給することにより、密閉容器1の破損を防止 するとともに、密閉容器1内をさらに窒素富化させていた。従来、上記のような 手段により密閉容器1内を窒素に富せることで、容器1内に収納する食品のいた みを防止していた。Due to the difference in the gas passing speed at that time, the first gas separation device 2 causes a pressure difference between the high pressure chamber 2b and the low pressure chamber 2c by the decompression pump 4a, and the high pressure chamber 2b side is enriched with nitrogen and the low pressure chamber 2b is enriched. The atmosphere on the 2c side is enriched with oxygen, carbon dioxide, and water, and the interior of the closed container 1 is enriched with nitrogen while being depressurized and dehumidified. The second gas separation device 3 also has the same function to enrich and dehumidify the high-pressure chamber 3b side. Then, in order to supplement the air drawn from the container 1 by the decompression pump 4a, the air is pushed in from the pushing pump 4d, the high pressure chamber 3b is enriched with nitrogen, and the dehumidified air is passed through the connecting pipe 9 to the container 1 By supplying this nitrogen-enriched and dehumidified atmosphere to the inside, damage to the closed container 1 was prevented, and the inside of the closed container 1 was further enriched with nitrogen. Conventionally, by enriching the closed container 1 with nitrogen by the above-mentioned means, it is possible to prevent the food contained in the container 1 from being used up.
【0005】[0005]
従来の冷蔵庫の窒素富化装置は以上のように構成されているので、密閉容器内 は窒素富化はされるが、除湿も同時に行われるため、密閉容器に収納する野菜な どを乾燥させてしまうという問題点があった。 Since the conventional refrigerator's nitrogen enrichment device is configured as described above, nitrogen is enriched in the closed container, but dehumidification is also performed at the same time, so it is necessary to dry vegetables stored in the closed container. There was a problem that it would end up.
【0006】 この考案は上記のような問題点を解消するためになされたもので、簡単、かつ 安価な構成で、従来の窒素富化の機能を損なうことなく、密閉容器内の乾燥を防 止でき、青果物などの長期保存を可能にできる冷蔵庫の窒素富化装置を得ること を目的とする。The present invention has been made to solve the above problems, and has a simple and inexpensive structure, which prevents the inside of a sealed container from being dried without impairing the conventional function of enriching nitrogen. The purpose of the present invention is to obtain a nitrogen enriching device for refrigerators that can be used for long-term storage of fruits and vegetables.

この考案に係る冷蔵庫の窒素富化装置は、密閉容器に供給する窒素富化空気の 供給路内に、窒素富化空気を加湿させる貯水部を設けたものである。 The nitrogen enriching device of the refrigerator according to the present invention is provided with a water storage portion for humidifying the nitrogen enriched air in the supply passage of the nitrogen enriched air supplied to the closed container.

この考案における窒素富化装置は、貯水部により供給される窒素富化空気が加 湿され、窒素富化空気をつくる際に失なわれる水分を補い、密閉容器内の乾燥を 防止する。 The nitrogen-enriching device according to the present invention humidifies the nitrogen-enriched air supplied by the water storage unit, supplements the water lost when producing the nitrogen-enriched air, and prevents the inside of the closed container from drying.

実施例1. 以下、この考案の一実施例を図について説明する。図1、図2において、従来 の技術と同一符号は同一、又は相当部分を示し、その詳細な説明は省略する。図 1において、11は上記密閉容器1内に窒素富化空気を供給する供給路である第 2ガス分離装置3の高圧室3bと密閉容器1を接続する接続管9の途中に設けた 貯水部で、高圧室3b側からの接続管9aの先端を貯水11aの水面下まで延設 させ、また、密閉容器1側の設管9bを貯水部11の上部に接続し、窒素富化空 気を、この貯水部11の貯水11a中を通過させて加湿させている。 Example 1. An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, the same reference numerals as those in the conventional technique indicate the same or corresponding portions, and detailed description thereof will be omitted. In FIG. 1, reference numeral 11 is a water supply part provided in the middle of a connecting pipe 9 connecting the high-pressure chamber 3b of the second gas separation device 3 and the closed container 1 which is a supply path for supplying nitrogen-enriched air into the closed container 1. Then, the tip of the connection pipe 9a from the high-pressure chamber 3b side is extended to below the water surface of the water storage 11a, and the installation pipe 9b on the closed container 1 side is connected to the upper part of the water storage section 11 to supply nitrogen-enriched air. The water is stored in the water storage section 11 and is humidified by passing through the water storage 11a.
【0010】 図2はこの図1の構成による窒素富化装置を備えた冷蔵庫の要部断面図であり 、図において、12は冷蔵庫本体で、内箱12aと外箱12b及びこの両箱12 a、12b間に充填した断熱材12cにより構成されている。1はこの冷蔵庫本 体12の下部に配設した青果物等の食品を貯蔵する密閉容器で、上部に蓋1aを 備え、かつ後部に、冷蔵庫本体12の後部に配設した上記第1ガス分離装置2を この密閉容器1内に露出させる穴1bを開設している。13はこの第1ガス分離 装置2と密閉容器1の穴1bの周囲をシールするパッキンで、第1ガス分離装置 2が密閉容器1内の雰囲気だけを吸い込むように塞いでいる。FIG. 2 is a cross-sectional view of essential parts of a refrigerator equipped with the nitrogen enriching device according to the configuration of FIG. 1. In the figure, 12 is a refrigerator body, which is an inner box 12a, an outer box 12b, and both boxes 12a. , 12b are filled with a heat insulating material 12c. Reference numeral 1 is a closed container for storing foods such as fruits and vegetables arranged in the lower part of the refrigerator main body 12, which has a lid 1a on the upper part and is arranged at the rear part of the refrigerator main body 12 at the rear part thereof. A hole 1b for exposing 2 in the closed container 1 is provided. A packing 13 seals the first gas separation device 2 and the periphery of the hole 1b of the closed container 1, and closes the first gas separation device 2 so as to suck only the atmosphere in the closed container 1.
【0011】 14は冷蔵庫本体12の下部に区画形成した圧縮機(図示せず)等を配設する 機械室で、この機械室14内に、上記窒素富化空気を密閉容器1内に供給する第 2ガス分離装置3と、減圧ポンプ4aと、押込ポンプ4d及び貯水部11をそれ ぞれ配設している。なお、この貯水部11の貯水11aは冷蔵庫本体12の上部 に備えた蒸発器(図示せず)からの除霜水をドレンホース(図示せず)により導 き貯めたものを利用している。15は冷蔵庫本体12の下部前面を開閉自在に塞 ぐ扉で、周囲にパッキン16を設けている。Numeral 14 is a machine room in which a compressor (not shown) and the like, which is partitioned and formed in the lower part of the refrigerator main body 12, is arranged. In the machine room 14, the nitrogen-enriched air is supplied into the closed container 1. The second gas separation device 3, the decompression pump 4a, the pushing pump 4d and the water storage section 11 are arranged respectively. As the water storage 11a of the water storage unit 11, defrosting water from an evaporator (not shown) provided on the upper portion of the refrigerator body 12 is introduced and stored by a drain hose (not shown). Reference numeral 15 denotes a door that opens and closes the lower front surface of the refrigerator main body 12, and a packing 16 is provided around the door.
【0012】 次に図2に関し動作について説明する。青果物貯蔵用の密閉容器1は蓋1aに より上部を、又扉15が閉められた状態で背面に設けられた第1ガス分離装置2 を露出する為の穴1bがパッキン13により密閉される。第1ガス分離装置2は 従来技術と同様の働きで上記容器1内を窒素富化、除湿及び減圧する。Next, the operation will be described with reference to FIG. The closed container 1 for storing fruits and vegetables is closed by a packing 13 at a top portion thereof by a lid 1a and a hole 1b for exposing a first gas separation device 2 provided at a rear surface in a state where a door 15 is closed. The first gas separator 2 enriches, dehumidifies, and depressurizes the inside of the container 1 in the same manner as in the prior art.
【0013】 また、第2ガス分離装置3も従来技術と同様に高圧室3bは窒素富化及び除湿 され、その空気は押込ポンプ4dにより接続管9aを介し一定量の貯水11aを 蓄えた貯水部11に送り込まれる。そして、接続管9aは貯水部11に蓄えられ た貯水11aの水面下まで達しており、上記ポンプ4dにより押し込まれた窒素 富化し、除湿された空気は貯水11a中を通過して加湿され、接続管9bを通じ 容器1内に送り込まれる。このため、密閉容器1内は乾燥することがない。Further, in the second gas separation device 3 as well as in the prior art, the high pressure chamber 3b is enriched with nitrogen and dehumidified, and its air is stored by a pushing pump 4d through a connecting pipe 9a to store a certain amount of stored water 11a. It is sent to 11. The connecting pipe 9a reaches below the surface of the stored water 11a stored in the water storage unit 11, and the nitrogen enriched and dehumidified by the pump 4d passes through the stored water 11a to be humidified and connected. It is fed into the container 1 through the pipe 9b. Therefore, the inside of the closed container 1 is not dried.
【0014】 また、上記実施例では、第1ガス分離装置2と第2ガス分離装置3の両方を備 えたものを示したが、第2ガス分離装置3だけを設ける構成としてもよく、密閉 容器1の上部などに適宜小さな穴などを設けて密閉容器1内の空気を逃し、第2 ガス分離装置3から供給される窒素富化空気だけで、この略密閉状態の密閉容器 1内を窒素富化の雰囲気にしても良く、上記実施例と同様の効果を奏する。Further, in the above-mentioned embodiment, the one provided with both the first gas separation device 2 and the second gas separation device 3 was shown, but it is also possible to provide only the second gas separation device 3 and to form a closed container. 1 is provided with an appropriate small hole or the like to allow the air in the closed container 1 to escape, and only the nitrogen-enriched air supplied from the second gas separation device 3 is filled with nitrogen in the closed container 1 in the substantially closed state. The atmosphere may be changed to the same effect as in the above embodiment.
【0015】 なお、上記実施例では貯水11aの水供給源として除霜水を利用したものを示 したが、自動製氷用として用いられる水の一部を供給源としてもよく、又その両 方を水の供給源としてもよく、上記実施例と同様の効果を奏する。Although the defrosting water is used as the water supply source of the water storage 11a in the above embodiment, a part of the water used for automatic ice making may be used as the supply source, or both of them may be used. It may be used as a water supply source and has the same effect as that of the above-mentioned embodiment.
【0016】 また、上記実施例では密閉容器1への窒素富化空気の供給路内である接続管9 の途中に貯水部11を設け、窒素富化空気を通すことにより貯水11aが自然に 蒸発し、加湿されるものを示したが、接続管9の途中や密閉容器1内に専用の加 湿装置を設けてもよく、上記実施例に比較して高価となるものの、同様に密閉容 器1内の乾燥を防ぐことができるものが得られる。Further, in the above embodiment, the water storage portion 11 is provided in the middle of the connecting pipe 9 which is in the supply passage of the nitrogen-enriched air to the closed container 1 and the water-enriched water 11a is naturally evaporated by passing the nitrogen-enriched air. However, although the humidifier is shown, a dedicated humidifier may be provided in the middle of the connecting pipe 9 or in the closed container 1, which is more expensive than the above-mentioned embodiment, but is similarly closed. The thing which can prevent the drying in 1 is obtained.
