 熱交換冷却器(図示せず)より冷却された冷気は野菜容器1及び蓋体3の外面を流通することで、野菜容器1が冷却され、内部に収納された食品が冷やされる。また、冷蔵庫運転時に冷却器から発生する除霜水は除霜水ホース10を通過する時に浄化フィルター11によって浄化されて、超音波霧化装置5の貯水容器7に供給される。 The cold air cooled by the heat exchange cooler (not shown) flows through the outer surfaces of the vegetable container 1 and the lid 3, thereby cooling the vegetable container 1 and cooling the food stored inside. Further, the defrost water generated from the cooler during the refrigerator operation is purified by the purification filter 11 when passing through the defrost water hose 10 and supplied to the water storage container 7 of the ultrasonic atomizer 5.
 次に湿度センサ8によって、庫内湿度が90%以下と検知されると、超音波霧化装置5が加湿を開始し、野菜容器1内の野菜等を新鮮に保持するための適度な湿度に調湿することができる。 Next, when the humidity sensor 8 detects that the internal humidity is 90% or less, the ultrasonic atomizing device 5 starts humidification, so that the humidity in the vegetable container 1 is kept at a suitable level. Humidity can be adjusted.
 一方、湿度センサ8によって庫内湿度が90%以上であると検知された場合、超音波霧化装置5は過度な加湿を停止する。その結果、超音波霧化装置5により、野菜室内をすばやく加湿することができ、野菜室内は常に高湿度となり、野菜等の蒸散作用が抑制され、野菜等の鮮度を保持することができる。 On the other hand, when the humidity sensor 8 detects that the internal humidity is 90% or more, the ultrasonic atomizer 5 stops excessive humidification. As a result, the ultrasonic atomizer 5 can quickly humidify the vegetable compartment, the humidity in the vegetable compartment is always high, the transpiration action of the vegetable or the like is suppressed, and the freshness of the vegetable or the like can be maintained.
 また、オゾン水ミスト装置を設けた冷蔵庫を示す(例えば、特許文献2参照)。 Moreover, the refrigerator provided with the ozone water mist apparatus is shown (for example, refer patent document 2).
 冷蔵庫は、野菜室の近傍にオゾン発生体、排気口、水道直結の水供給経路、およびオゾン水供給経路を有している。オゾン水供給経路は野菜室に導かれている。オゾン発生体は水道直結の水供給部に連結している。また、排気口はオゾン水供給経路に連結するよう構成されている。また、野菜室内には超音波素子が備えられている。オゾン発生体で発生したオゾンは水と接触させて処理水としてのオゾン水にされる。生成したオゾン水は冷蔵庫の野菜室に導かれ、超音波振動子により霧化され、野菜室に噴霧される。 The refrigerator has an ozone generator, an exhaust port, a water supply path directly connected to the water supply, and an ozone water supply path in the vicinity of the vegetable room. The ozone water supply route is led to the vegetable room. The ozone generator is connected to a water supply unit directly connected to the water supply. Further, the exhaust port is configured to be connected to the ozone water supply path. In addition, an ultrasonic element is provided in the vegetable compartment. Ozone generated by the ozone generator is brought into contact with water to become ozone water as treated water. The generated ozone water is guided to the vegetable compartment of the refrigerator, atomized by an ultrasonic vibrator, and sprayed to the vegetable compartment.
 近年、冷蔵庫の庫内や保存している食品や食品容器へ対する除菌や冷蔵庫空気の脱臭ニーズが高まっている。 In recent years, there is a growing need for sterilization of refrigerators and stored foods and food containers, and deodorization of refrigerator air.
 従来、このニーズに応える機能を備えた冷蔵庫として、殺菌性又は抗菌性の処理水を超音波霧化装置にてミスト状にして貯蔵室へ供給し、そのミスト成分が貯蔵室の庫壁や保存している食品や食品容器の表面の除菌を行うことや、冷蔵庫空気の脱臭を行っている(例えば、特許文献2参照)。 Conventionally, as a refrigerator equipped with a function that meets this need, bactericidal or antibacterial treated water is supplied to the storage room in the form of a mist using an ultrasonic atomizer, and the mist components are stored in the storage room walls or preserved. The surface of foods and food containers being sterilized and the refrigerator air are deodorized (for example, see Patent Document 2).
 図30と図31は特許文献1に記載された従来のミスト生成装置を備えた冷蔵庫を示すものである。 30 and 31 show a refrigerator equipped with the conventional mist generating device described in Patent Document 1. FIG.
 図に示すように、野菜室7は冷蔵庫本体Rの下部に設けられ、その前面開口は開閉自在に引き出される引出し扉D2により閉止されるようになっている。また、野菜室7は仕切板(図示せず)によりその上方の冷蔵室(図示せず)と仕切られている。 As shown in the figure, the vegetable compartment 7 is provided in the lower part of the refrigerator main body R, and its front opening is closed by a drawer door D2 that can be freely opened and closed. Moreover, the vegetable compartment 7 is partitioned off from the upper refrigerator compartment (not shown) by a partition plate (not shown).
 また、引出し扉D2には固定ハンガ(図示せず)が固定され、この固定ハンガに野菜等の食品を収納する野菜容器7Bが搭載されている。野菜室7にはミスト生成装置として超音波振動子8、冷蔵庫近傍にオゾン発生装置(図示せず)と水道直結の水供給経路(図示せず)オゾン水供給経路(図示せず)を有している。また、オゾン水供給経路は野菜室へ導かれ超音波霧化装置8に連結している。 Also, a fixed hanger (not shown) is fixed to the drawer door D2, and a vegetable container 7B for storing food such as vegetables is mounted on the fixed hanger. The vegetable room 7 has an ultrasonic vibrator 8 as a mist generating device, an ozone generator (not shown) near the refrigerator, and a water supply path (not shown) directly connected to the water supply, an ozone water supply path (not shown). ing. The ozone water supply path is led to the vegetable room and connected to the ultrasonic atomizer 8.
 以上のように構成された冷蔵庫において、以下にその動作について説明する。 The operation of the refrigerator configured as described above will be described below.
 オゾン発生体で発生したオゾンは水と接触させて処理水としてのオゾン水にされる。生成したオゾン水は冷蔵庫の野菜室に導かれ、超音波振動子8によりミストへと霧化され、野菜室に噴霧される。この霧化されたオゾン水ミストにより、冷蔵庫の野菜室7に庫壁や食品等の表面に付着している細菌類の抗菌を行うことや野菜室7の空気の脱臭を行うことができる。 Ozone generated by the ozone generator is brought into contact with water to become ozone water as treated water. The generated ozone water is guided to the vegetable compartment of the refrigerator, atomized into mist by the ultrasonic vibrator 8, and sprayed to the vegetable compartment. With this atomized ozone water mist, it is possible to perform antibacterial action of bacteria adhering to the surface of the warehouse wall or food in the vegetable compartment 7 of the refrigerator, or to deodorize the air in the vegetable compartment 7.
 近年、さまざまな地域のさまざまな食材が冷蔵庫に保存されることから、冷蔵庫庫内に保存される食品から発生する臭気の脱臭や庫内除菌のニーズは非常に高く、冷蔵庫庫内の除菌・脱臭を目的として、各種手法を用いた除菌・脱臭装置の開発がさかんである。 In recent years, since various ingredients in various regions are stored in refrigerators, there is a very high need for deodorization and sterilization in food stored in refrigerators.・ For the purpose of deodorization, development of sterilization / deodorization equipment using various methods is in progress.
 従来の除菌装置は、フィルターを風路中に配置し、フィルターを通過する空気中の除菌・脱臭を行う除菌装置がある(例えば、特許文献3参照)。また、従来の光触媒を用いた除菌装置としては、酸化チタンを担持させたフィルター状の部材に紫外線を照射し、光触媒反応を用いて冷蔵庫の有機物質などを酸化、分解して除菌・脱臭を行うものなど複数の方法が存在している。 A conventional sterilization apparatus includes a sterilization apparatus that disposes a filter in an air passage and performs sterilization / deodorization in the air passing through the filter (see, for example, Patent Document 3). In addition, as a sterilization device using a conventional photocatalyst, a filter-like member carrying titanium oxide is irradiated with ultraviolet rays, and the organic substances in the refrigerator are oxidized and decomposed using a photocatalytic reaction to sterilize and deodorize. There are several ways to do this.
 以下、図面を参照しながら上記従来の除菌装置について説明する。 Hereinafter, the conventional sterilization apparatus will be described with reference to the drawings.
 図51は、冷蔵室戻り空気吸込部に除菌装置を装着した従来の冷蔵庫の部分縦断面図である。 FIG. 51 is a partial vertical cross-sectional view of a conventional refrigerator in which a sterilization apparatus is attached to the refrigerating room return air suction section.
 図51に示す除菌装置は、除菌フィルター1、脱臭フィルター2、取付枠3から構成される。ここで除菌フィルター1は、珪素、アルミニウム、ナトリウム等の酸化物からなるゼオライトに銀を配合したものをハニカム状に成型したもので、通風抵抗の関係でセル数100~250個/平方インチ、開口率70~80%、厚さ8mm程度のものを用いている。 51 includes a sterilization filter 1, a deodorization filter 2, and a mounting frame 3. Here, the sterilization filter 1 is formed by mixing a zeolite composed of oxides of silicon, aluminum, sodium and the like into a honeycomb shape, and the number of cells is 100 to 250 per square inch in relation to ventilation resistance. An aperture ratio of 70 to 80% and a thickness of about 8 mm are used.
 脱臭フィルター2は、マンガン酸化物と珪素やアルミニウムの酸化物と混連しハニカム状に成型したものであるが、この場合セル数や開口率も前記除菌フィルターとほぼ同じ場合が多い。これら除菌フィルター1と脱臭フィルター2は取付枠3で一体に固定されている。 The deodorizing filter 2 is formed by mixing a manganese oxide and an oxide of silicon or aluminum into a honeycomb shape, and in this case, the number of cells and the aperture ratio are often almost the same as the sterilization filter. The sterilizing filter 1 and the deodorizing filter 2 are integrally fixed by a mounting frame 3.
 図49において、冷蔵庫の最上部に冷凍室5、その下方に冷蔵室6が配設され、冷凍室5および冷蔵室6の背面に冷却器11が配置されている。また、冷凍室5と冷蔵室6との間の断熱部8には冷気通路9が配設され、冷気通路9には吸込部7側に除菌フィルター1と除菌フィルター1の奥側に脱臭フィルター2とが一体に具備されている。 49, the freezer compartment 5 is disposed at the top of the refrigerator, the refrigerator compartment 6 is disposed below the refrigerator compartment, and the cooler 11 is disposed on the back of the refrigerator compartment 5 and refrigerator compartment 6. Further, a cool air passage 9 is disposed in the heat insulating portion 8 between the freezer compartment 5 and the refrigerator compartment 6, and the cool air passage 9 is deodorized on the suction portion 7 side and on the back side of the disinfection filter 1. The filter 2 is integrally provided.
 以上のように構成された冷蔵庫について以下にその動作を説明する。 The operation of the refrigerator configured as described above will be described below.
 冷却器11で生成された冷気は一部が冷凍室5に流れ、一部が下方の冷蔵室6やその他の貯蔵室に流れる。各部を循環した冷気は、戻り空気の吸込部7から冷気通路9を経て、冷却器11に向かう。この時の冷気通路9における風速は0.5m/sec程度である。 A part of the cold air generated by the cooler 11 flows into the freezer compartment 5 and a part thereof flows into the refrigerator compartment 6 and other storage rooms below. The cold air circulated through each part goes from the return air suction part 7 to the cooler 11 through the cold air passage 9. The wind speed in the cool air passage 9 at this time is about 0.5 m / sec.
 冷気通路9を通る冷気は、除菌装置より除菌および脱臭が行われる。具体的には、まず除菌フィルター1にて塵埃とともに細菌やかびの胞子が捕捉され、脱臭フィルター2にて有臭成分の化学変化を進められ脱臭が行われる。 The cold air passing through the cold air passage 9 is sterilized and deodorized by a sterilization apparatus. Specifically, first, bacteria and mold spores are captured together with dust by the sterilization filter 1, and chemical changes of odorous components are advanced by the deodorization filter 2 to perform deodorization.
 以上のように、脱臭と除菌用フィルターを組み合わせることで小型化を図り、当該除菌・脱臭フィルターを冷気通路内に設けることで、冷蔵庫内全体の雰囲気に対し効率よく除菌・脱臭が行える。従って、雑菌および悪臭のないクリーンな冷蔵庫を実現できることとなる。 As described above, downsizing is achieved by combining deodorizing and sterilizing filters, and by disposing the sterilizing / deodorizing filter in the cool air passage, sterilization / deodorizing can be efficiently performed with respect to the entire atmosphere in the refrigerator. . Therefore, a clean refrigerator free from germs and bad odor can be realized.

 しかしながら、上記従来の構成では、超音波振動素子で水またはオゾン水を霧化する方式のため、霧化した水粒子またはオゾン水粒子が微細とならず粒子が大きいことで重量が重いミストである為、拡散性が低く庫内に拡散させて噴霧することができず、さらに超音波霧化装置5とオゾン水ミスト装置とが設けられている野菜室内にのみ噴霧されていた。 However, in the above-described conventional configuration, since the water or ozone water is atomized by the ultrasonic vibration element, the atomized water particles or ozone water particles are not fine and the particles are large, and thus the mist is heavy. Therefore, the diffusibility is low and it cannot be sprayed by being diffused in the cabinet, and is sprayed only in the vegetable room where the ultrasonic atomizer 5 and the ozone water mist device are provided.
 また、水粒子またはオゾン水粒子を自然拡散により他の貯蔵室に供給するために噴霧量を増加させるもしくは連続噴霧すると、野菜等の食品が水腐れを起こす、もしくは、庫内が結露することによる保鮮性の低下および品質低下が懸念されるという課題がある。 Also, when water spray or ozone water particles are supplied to other storage chambers by natural diffusion, increasing the spray amount or continuous spraying causes food such as vegetables to rot, or condensation in the storage There is a problem that deterioration of freshness and quality are concerned.
 本発明は、噴霧装置を設けた貯蔵室だけでなく他の貯蔵室へもミスト粒子を供給することで、冷蔵庫の全貯蔵室にわたって、貯蔵室の壁面や収納している食品表面に付着している細菌類の抗菌を行うとともに、食品等に起因する貯蔵室内の冷気の脱臭を行なうことを可能とする冷蔵庫を提供することを目的とする。 By supplying mist particles not only to the storage chamber provided with the spray device but also to other storage chambers, the present invention adheres to the wall surface of the storage chamber and the food surface contained therein over all the storage chambers of the refrigerator. Another object of the present invention is to provide a refrigerator capable of performing antibacterial action on bacteria and deodorizing cold air in a storage room caused by food or the like.
 また、上記従来の構成では、ミスト生成装置が設置されている野菜室に対してのみ殺菌性や抗菌性のあるミストを安定的に供給し、冷蔵庫の他の貯蔵室へ対して有用な効果を発揮できていなかった。 Moreover, in the said conventional structure, only the vegetable room in which the mist production | generation apparatus is installed stably supplies bactericidal and antibacterial mist, and has a useful effect with respect to the other storage room of a refrigerator. It was not able to be demonstrated.
 また、ミストを大量に噴霧することで他の貯蔵室へ供給することも考えられるが、その場合には、庫内結露や野菜の水腐れといった課題があった。 Also, it is conceivable to supply mist to other storage rooms by spraying a large amount of mist, but in that case, there are problems such as dew condensation in the warehouse and water rot of vegetables.
 本発明は、少ない量のミスト供給であっても冷蔵庫の全ての貯蔵室の庫壁や食品等の表面に付着したカビや細菌酵母およびウィルス等の微生物の増加を抑制することができることを目的とする。 It is an object of the present invention to suppress an increase in microorganisms such as mold, bacterial yeast, and viruses attached to the surfaces of storage walls of all storage rooms and the surface of foods even with a small amount of mist supply. To do.
 また、上記従来の構成では、超音波振動素子で水またはオゾン水を霧化する方式のため、霧化した水粒子またはオゾン水粒子が微細とならず粒子が大きいことで重量が重いミストである為、拡散性が低く庫内に拡散させて噴霧することができず、さらに超音波霧化装置5とオゾン水ミスト装置とが設けられている野菜室内にのみ噴霧されていた。 Moreover, in the said conventional structure, since it is a system which atomizes water or ozone water with an ultrasonic vibration element, it is a mist with a heavy weight because the atomized water particle or ozone water particle does not become fine but is large. Therefore, the diffusibility is low and it cannot be sprayed by being diffused in the cabinet, and is sprayed only in the vegetable room where the ultrasonic atomizer 5 and the ozone water mist device are provided.
 また、水粒子またはオゾン水粒子を自然拡散により他の貯蔵室に供給するために噴霧量を増加させるもしくは連続噴霧すると、野菜等の食品が水腐れを起こす、もしくは、庫内が結露することによる保鮮性の低下および品質低下が懸念されるという課題がある。 Also, when water spray or ozone water particles are supplied to other storage chambers by natural diffusion, increasing the spray amount or continuous spraying causes food such as vegetables to rot, or condensation in the storage There is a problem that deterioration of freshness and quality are concerned.
 本発明は、噴霧装置によって発生させたミストをより効果的に各貯蔵室へ配分することで、冷蔵庫の全貯蔵室において、最適な効果を発揮する噴霧装置を備えた冷蔵庫を提供することを目的とする。 An object of the present invention is to provide a refrigerator provided with a spraying device that exhibits an optimum effect in all storage rooms of the refrigerator by more effectively distributing the mist generated by the spraying device to each storage room. And
 また、上記従来の構成では、冷蔵室の冷気の風路の上流側に脱臭手段を設置しているため、触媒を通過する冷気には効果があっても、触媒を通過しない冷蔵室内の空気に直接の脱臭効果はないという課題があった。 Further, in the above conventional configuration, the deodorizing means is installed on the upstream side of the cool air flow path in the refrigerating room, so even if the cold air passing through the catalyst is effective, the air in the refrigerating room does not pass through the catalyst. There was a problem that there was no direct deodorizing effect.
 本発明は、上記従来の課題を解決するもので、複数の貯蔵室内の空気と循環している冷気の両方を効率的に除菌・脱臭することができる冷蔵庫を提供することを目的としている。 This invention solves the said conventional subject, and it aims at providing the refrigerator which can disinfect and deodorize efficiently both the air in several storage chambers, and the circulating cold air.
 上記従来の課題を解決するために、本発明の冷蔵庫は、複数の貯蔵室と、冷却器とファンとを収納し前記複数の貯蔵室と風路を介して繋がる冷却室と、ミストを噴霧する噴霧装置とを有する冷蔵庫であって、前記噴霧装置は、前記複数の貯蔵室のうちの少なくとも一つの貯蔵室内に設けられた外郭ケースの内部に収納されており、前記外郭ケースは前記貯蔵室から前記風路へ冷気を戻す吸込み口と連結されており、前記外郭ケースは前記貯蔵室と連通する開口部が設けられており、少なくとも前記ファンが動作するとき、前記噴霧装置によりミストが噴霧されるされるものである。 In order to solve the above-described conventional problems, a refrigerator according to the present invention sprays mist, a plurality of storage chambers, a cooling chamber that houses a cooler and a fan, and is connected to the plurality of storage chambers via an air passage. A refrigerator having a spraying device, wherein the spraying device is housed in an outer case provided in at least one of the plurality of storage chambers, and the outer case is separated from the storage chamber. The outer case is connected to a suction port for returning cool air to the air passage, and the outer case is provided with an opening communicating with the storage chamber, and at least when the fan operates, the mist is sprayed by the spray device. It is what is done.
 これによって、噴霧装置から発生するミストは、まず外郭ケース内に拡散するので、噴霧装置が設けられた貯蔵室に直接に全量が供給されることがない。さらに、外郭ケースは貯蔵室の吸込み口に連結されているため、ミストが複数の貯蔵室へ拡散できるとともに、ミストはファンが動作するときに噴霧されるので、ファンによる強制対流を利用して、複数の貯蔵室へミストが供給される構成が冷蔵庫において実現することができる。 This allows the mist generated from the spraying device to first diffuse into the outer case, so that the entire amount is not supplied directly to the storage chamber provided with the spraying device. In addition, since the outer case is connected to the suction port of the storage chamber, mist can diffuse to multiple storage chambers, and since the mist is sprayed when the fan operates, using forced convection by the fan, A configuration in which mist is supplied to a plurality of storage rooms can be realized in the refrigerator.
 また、上記従来の課題を解決するために、本発明の冷蔵庫は、複数の貯蔵室と、冷却器を収納し前記複数の貯蔵室と風路を介して繋がる冷却室と、ミストを噴霧する噴霧装置とを有する冷蔵庫であって、 前記噴霧装置は、コロナ放電を用いた霧化方式であり、前記貯蔵室の一つである第一貯蔵室に前記噴霧装置から発生したミストを貯留する専用区画を有し、前記専用区画に貯留されたミストの供給対象である貯蔵室を切り換えることが可能な分流手段を備えたものである。 In order to solve the above-described conventional problems, a refrigerator according to the present invention includes a plurality of storage rooms, a cooling chamber that houses a cooler and is connected to the plurality of storage rooms via an air passage, and a spray that sprays mist. The spraying device is an atomization method using corona discharge, and is a dedicated compartment for storing mist generated from the spraying device in a first storage chamber that is one of the storage chambers. And a diversion means capable of switching the storage chamber to which the mist stored in the dedicated section is to be supplied.
 これによって、噴霧装置から発生するミストは、まず専用区画内に充満した上で、分流手段によって必要な貯蔵室へ切り換えて確実に供給されるので、必要に応じた任意の貯蔵室へ速やかにミスト供給がなされる冷蔵庫を提供することが可能となる。 As a result, the mist generated from the spraying device is filled in the dedicated compartment first and then switched to the necessary storage room by the diverting means to be surely supplied, so that the mist can be promptly transferred to any storage room as needed. It is possible to provide a refrigerator to be supplied.
 また、本発明の冷蔵庫は、複数の貯蔵室と、前記貯蔵室を冷却する冷気を生成する冷却室と、前記冷気が搬送される風路と、前記貯蔵室へ供給するミストを生成する噴霧装置とを有する冷蔵庫であって、前記貯蔵室は、前記噴霧装置が備えられる前記貯蔵室の一つである第一貯蔵室を備え、前記第一貯蔵室以外の貯蔵室へは前記噴霧装置によって生成されたミストを断続的に供給することを特徴とするものである。 The refrigerator of the present invention includes a plurality of storage rooms, a cooling room that generates cool air for cooling the storage room, an air passage through which the cold air is conveyed, and a spray device that generates mist to be supplied to the storage room. The storage room includes a first storage room that is one of the storage rooms in which the spraying device is provided, and a storage room other than the first storage room is generated by the spraying device. The supplied mist is supplied intermittently.
 これによって、断続的なミスト供給により各貯蔵室のミスト濃度が変動し、このミスト濃度変動により貯蔵室の庫壁や食品等の表面に付着したカビや細菌酵母およびウィルス等の微生物へ対し生体ストレスを与えることができるようになったので、ミスト発生量を抑えた少ない量のミスト供給であっても冷蔵庫の全ての貯蔵室へ少量のミスト供給量でも貯蔵室の庫壁や食品等の表面に付着したカビや細菌酵母およびウィルス等の微生物の増加を抑制することができる。 As a result, the mist concentration in each storage room fluctuates due to intermittent mist supply, and this mist concentration fluctuation causes biological stress to microorganisms such as mold, bacterial yeast, and viruses adhering to the surface of the storage room wall and food. Therefore, even if a small amount of mist is supplied while suppressing the amount of mist generated, even a small amount of mist can be supplied to the storage wall of the storage room or the surface of food. An increase in microorganisms such as attached mold, bacterial yeast and virus can be suppressed.
 また、上記従来の課題を解決するために、本発明の冷蔵庫は、複数の貯蔵室と、冷却器を収納し前記複数の貯蔵室と風路を介して繋がる冷却室と、ミストを噴霧する噴霧装置とを有する冷蔵庫であって、前記複数の貯蔵室は、冷蔵温度帯で保持される冷蔵室と前記冷蔵温度帯と同等または高い温度設定とする野菜室とを少なくとも備え、前記貯蔵室内の収納部とは独立して前記ミストを貯留する専用区画を有するとともに、前記専用区画から前記冷蔵室への前記ミスト供給は、ファンを用いた強制対流とし、前記専用区画から前記野菜室への前記ミスト供給は、自然対流とするミスト供給経路を備えたものである。 In order to solve the above-described conventional problems, a refrigerator according to the present invention includes a plurality of storage rooms, a cooling chamber that houses a cooler and is connected to the plurality of storage rooms via an air passage, and a spray that sprays mist. The plurality of storage rooms include at least a refrigeration room maintained in a refrigeration temperature zone and a vegetable room set to a temperature equal to or higher than the refrigeration temperature zone, and storage in the storage room The mist supply from the dedicated compartment to the refrigerator compartment is forced convection using a fan, and the mist from the dedicated compartment to the vegetable compartment Supply is provided with a mist supply path for natural convection.
 また、本発明の冷蔵庫は、 複数の貯蔵室と、冷却器を収納し前記複数の貯蔵室と風路を介して繋がる冷却室と、ミストを噴霧する噴霧装置とを有し、前記複数の貯蔵室は、前記ミストを噴霧することによって主として除菌効果を期待する貯蔵室と、主として野菜の栄養素を増加させるもしくは野菜の低温障害を抑制する効果を期待する貯蔵室とを有し、前記除菌効果を期待する貯蔵室への前記ミスト供給は、ファンを用いた強制対流とし、前記野菜室への前記ミスト供給は自然対流とするミスト供給経路を備えたものである。 The refrigerator of the present invention includes a plurality of storage chambers, a cooling chamber that houses a cooler and is connected to the plurality of storage chambers via an air passage, and a spray device that sprays mist. The chamber has a storage chamber that is mainly expected to have a sterilizing effect by spraying the mist, and a storage chamber that mainly has an effect of increasing the nutrients of vegetables or suppressing the low-temperature damage of vegetables. The mist supply to the storage room where an effect is expected is a forced convection using a fan, and the mist supply to the vegetable room is provided with a mist supply path for natural convection.
 これによって、貯蔵される食品が多岐にわたることで最も除菌もしくは消臭効果を発揮したい冷蔵室、または主として除菌効果を期待する貯蔵室においては、前記専用区画から強制対流によってミストを供給することで濃いミストを供給することができ、さらに野菜室または主に野菜を収納する貯蔵室においては、前記専用区画から自然対流によってミストを供給することで強制対流を用いるよりもミストの濃度を薄くすることができ、ミストの配分の仕方を工夫することで必要に応じた任意の貯蔵室に合わせてミストの濃度調整がなされる冷蔵庫を提供することが可能となる。 In this way, in a refrigerated room where sterilization or deodorization is most desired due to a wide variety of foods to be stored, or in storage rooms where sterilization is mainly expected, mist is supplied from the dedicated compartment by forced convection. In a vegetable room or a storage room that mainly stores vegetables, the mist concentration can be reduced by using natural convection from the dedicated compartment, compared to forced convection. It is possible to provide a refrigerator in which the concentration of mist is adjusted according to any storage room as required by devising the way of mist distribution.
 また、上記従来の課題を解決するために、本発明の冷蔵庫は、断熱材で構成され、内部に貯蔵室を形成する断熱箱体と、前記断熱箱体の開口部に開閉自在に取り付けられる扉体と、前記断熱箱体内の空気を冷却し冷気を生成する冷却手段と、前記貯蔵室と前記冷却手段との間で前記冷気をファンにより循環させる風路とを有し、前記貯蔵室内の脱臭を行う第1の脱臭装置と、前記風路において前記貯蔵室よりも下流側に備えられた第2の脱臭装置とを備え、前記第1の脱臭装置と前記第2の脱臭装置とは異なる脱臭方式である。 Moreover, in order to solve the said conventional subject, the refrigerator of this invention is comprised with the heat insulating material, the heat insulation box which forms a storage chamber inside, and the door attached to the opening part of the said heat insulation box so that opening and closing is possible. Body, cooling means for cooling the air in the heat insulation box to generate cool air, and an air passage for circulating the cool air by a fan between the storage chamber and the cooling means, and deodorizing the storage chamber And a second deodorizing device provided downstream of the storage chamber in the air passage, wherein the first deodorizing device and the second deodorizing device are different from each other. It is a method.
 また、本発明は断熱材で構成され、内部に貯蔵室を形成する断熱箱体と、前記断熱箱体の開口部に開閉自在に取り付けられる扉体と、前記断熱箱体内の空気を冷却し冷気を生成する冷却手段と、前記貯蔵室と前記冷却手段との間で前記冷気をファンにより循環させる風路とを有し、前記風路において前記貯蔵室の冷気の上流側の空間にOHラジカルを含んだミストを噴霧する霧化装置を設置するとともに前記風路において貯蔵室の下流側に触媒を保持した脱臭装置を備えたものである。 The present invention also includes a heat insulating box that is formed of a heat insulating material and forms a storage chamber therein, a door that is attached to the opening of the heat insulating box so as to be openable and closable, and cools and cools air in the heat insulating box. A cooling means for generating the air, and an air passage for circulating the cold air by a fan between the storage chamber and the cooling means, and in the air passage, OH radicals are introduced into the space upstream of the cold air in the storage chamber. An atomizing device for spraying the contained mist is installed, and a deodorizing device for holding a catalyst on the downstream side of the storage chamber in the air passage is provided.
 これによって、除菌・脱臭効果のあるOHラジカルを含んだミストが貯蔵室中に拡散され、直接貯蔵室内の空間を除菌・脱臭し、さらに、OHラジカルを含んだミストが脱臭効果のある触媒に接触することで触媒の効果を高め、貯蔵室内の空気と循環している冷気の両方を効率的に除菌・脱臭することができる。 As a result, mist containing OH radicals having sterilizing and deodorizing effects is diffused into the storage room, directly sterilizing and deodorizing the space in the storage room, and mist containing OH radicals has a deodorizing effect. The effect of the catalyst can be enhanced by contact with, and both the air in the storage chamber and the circulating cold air can be sterilized and deodorized efficiently.
 本発明の冷蔵庫は、複数の貯蔵室へミストが供給される構成が冷蔵庫において実現することができるので、冷蔵庫の複数の貯蔵室にわたって、ミストによる有用な効果を発揮できる冷蔵庫を提供することができる。 In the refrigerator according to the present invention, the configuration in which the mist is supplied to the plurality of storage rooms can be realized in the refrigerator.

 また、ミスト排出口の面積の大きさによって、噴霧装置が設けられた貯蔵室へのミスト供給量を調整することができ、他貯蔵室への過剰なミスト拡散を抑制することができ、冷蔵庫全室に対して均衡が取れたミスト拡散が実現される。 In addition, the amount of mist supplied to the storage room provided with the spraying device can be adjusted according to the size of the area of the mist discharge port, and excessive mist diffusion to other storage rooms can be suppressed. Mist diffusion balanced against the chamber is realized.
 第14の発明は、噴霧装置は、空気中の水分を結露させることで生成する結露水を用いてミストが噴霧されるものであって、前記専用区画において前記噴霧装置に対する上流側に水分供給口が設けられ、前記噴霧装置に対する下流側にミスト拡散調整材が設けられている冷蔵庫である。 According to a fourteenth aspect of the invention, in the spray device, the mist is sprayed using the condensed water generated by the condensation of moisture in the air, and the moisture supply port is provided upstream of the spray device in the dedicated section.

 これによって、主にファンが停止している時に、外郭ケース内で拡散するミストを水分供給口だけでなく、ミスト排出口からも噴霧装置が設けられた貯蔵室へ供給することができる。 Thus, when the fan is stopped, the mist that diffuses in the outer case can be supplied not only from the water supply port but also from the mist discharge port to the storage chamber provided with the spray device.
 また、ミスト排出口の面積の大きさによって、噴霧装置が設けられた貯蔵室へのミスト供給量を調整することができ、他貯蔵室への過剰なミスト拡散を抑制することができ、冷蔵庫全室に対して均衡が取れたミスト拡散が実現される。 In addition, the amount of mist supplied to the storage room provided with the spraying device can be adjusted according to the size of the area of the mist discharge port, and excessive mist diffusion to other storage rooms can be suppressed. Mist diffusion balanced against the chamber is realized.
 ファン作動時には水分供給口やミスト排出口から貯蔵室内の高湿な冷気が外郭ケース内に取り込まれるが、水分供給口からの高湿冷気の風速が大きくなると、噴霧装置において結露を発生させられないことがあるが、外郭ケースにおける噴霧装置に対する上流側に水分供給口が設けられ、噴霧装置に対する下流側にミスト拡散調整材が設けられていることで、吸い込み口を通りその他貯蔵室へ拡散するミストはミスト拡散調整材が障壁となり、他貯蔵室への過剰なミスト拡散を抑制することができ、冷蔵庫全室に対して均衡が取れたミスト拡散が実現される。 When the fan is operating, high-humidity cold air in the storage chamber is taken into the outer case from the moisture supply port and mist discharge port. However, when the wind speed of the high-humidity cold air from the moisture supply port increases, condensation cannot be generated in the spray device.

Since the mist can be supplied indirectly according to the required amount, the mist can be supplied indirectly more efficiently, and the amount of mist generated from the spray device can be further suppressed. became.

It became possible to supply to other than one storage room, and further, the amount of mist generated from the spraying device could be suppressed.

The increase in microorganisms can be suppressed by storing food in the dedicated compartment.
 第24の発明の冷蔵庫は、前記専用区画は前記吐出風路および前記吸込み風路から独立し、かつ、前記吐出風路または前記吸込み風路と連通していることを特徴とするものである。 The refrigerator according to a twenty-fourth aspect is characterized in that the dedicated section is independent of the discharge air passage and the suction air passage and communicates with the discharge air passage or the suction air passage.
 これにより、前記ミスト専用空間が吐出風路や吸込み風路内に備えていないので、前記冷凍サイクルの冷気の循環の支障をきたさないことに加え、前記専用区画もしくは吐出風路とは連結しているのでミストを風路へより効率よく供給することができるようになり、さらに噴霧装置から発生するミスト量を抑えることができるようになった。 As a result, the mist dedicated space is not provided in the discharge air passage or the suction air passage, so that it does not interfere with the circulation of the cold air in the refrigeration cycle, and is connected to the dedicated section or the discharge air passage. As a result, the mist can be supplied to the air passage more efficiently, and the amount of mist generated from the spray device can be suppressed.
 第25の発明の冷蔵庫は、前記専用区画は前記吐出風路および前記吸込み風路から独立し、かつ、前記吐出風路または前記吸込み風路と連通していることを特徴とするものである。 In the refrigerator of the 25th invention, the dedicated section is independent of the discharge air passage and the suction air passage, and communicates with the discharge air passage or the suction air passage.
 これにより、前記冷凍サイクルにより前記貯蔵室を冷却するときは、前記専用区画から吸込み風路へミストを供給することによって前記冷凍サイクルの冷気の流れを利用して前記第一貯蔵室とは別の前記特定各貯蔵室以外へミストを供給することができたことに加え、前記冷凍サイクルにより各貯蔵室を冷却しないときも、前記吸込み風路を経由して前記専用区画に蓄えられたミストを前記貯蔵室へ供給することができるようになったので、前記冷凍サイクルにより冷蔵庫内に冷却が循環していないときも、前記貯蔵室へ対してミストを供給することができるようになり、さらに効率よくミストを冷蔵庫の各貯蔵室へ供給することができるようになり、さらに噴霧装置から発生するミスト量を抑えることができるようになった。 Accordingly, when the storage chamber is cooled by the refrigeration cycle, the mist is supplied from the dedicated section to the suction air passage, thereby using the flow of the cold air of the refrigeration cycle and different from the first storage chamber. In addition to being able to supply mist to other than the specific storage chambers, when the storage chambers are not cooled by the refrigeration cycle, the mist stored in the dedicated section via the suction air passage is Since it can now be supplied to the storage room, it becomes possible to supply mist to the storage room even when cooling is not circulated in the refrigerator by the refrigeration cycle. Mist can be supplied to each storage room of the refrigerator, and further, the amount of mist generated from the spray device can be suppressed.
 第26の発明の冷蔵庫は、前記専用区画は、前記貯蔵室天面後方側に備えることを特徴とするものである。 In the refrigerator of the twenty-sixth aspect of the invention, the dedicated section is provided on the rear side of the top surface of the storage room.
 これにより、前記冷凍サイクルにより各貯蔵室を冷却しないときは、前記貯蔵室の天面に備えられている専用区画に蓄えたミストは自重を利用した自然拡散により、前記貯蔵室全体へ供給されることができるようになり、さらに効率よくミストを前記貯蔵室へ供給することができるようになり、さらに噴霧装置から発生するミスト量を抑えることができるようになった。 Accordingly, when each storage room is not cooled by the refrigeration cycle, the mist stored in the dedicated section provided on the top surface of the storage room is supplied to the entire storage room by natural diffusion using its own weight. As a result, mist can be supplied to the storage chamber more efficiently, and the amount of mist generated from the spray device can be suppressed.
 第27の発明の冷蔵庫は、前記専用区画は前記貯蔵室へ接した面に開口部を設けてあることを特徴とするものである。 The refrigerator according to a twenty-seventh aspect is characterized in that the dedicated section is provided with an opening on a surface in contact with the storage room.
 これにより、前記冷凍サイクルにより各貯蔵室を冷却しているとき、していないときにかかわらず、前記専用区画に蓄えられたミストは前記貯蔵室へ接した面に設けてある開口部を経由して前記貯蔵室へミストを供給することができるようになったので、さらに効率よく前記貯蔵室へミストを供給することができるようになり、さらに噴霧装置から発生するミスト量を抑えることができるようになった。 Thus, regardless of whether or not each storage room is cooled by the refrigeration cycle, the mist stored in the dedicated section passes through the opening provided on the surface in contact with the storage room. Since the mist can be supplied to the storage chamber, the mist can be supplied to the storage chamber more efficiently, and the amount of mist generated from the spray device can be suppressed. Became.
 第28の発明の冷蔵庫は、前記貯蔵室のミスト濃度差が、ミストに含まれるオゾン濃度で0.01ppm以上であることを特徴とするものである。 The refrigerator of the 28th invention is characterized in that the difference in mist concentration in the storage chamber is 0.01 ppm or more in terms of ozone concentration contained in the mist.
 これにより、貯蔵室の庫壁や食品等の表面に付着したカビや細菌酵母およびウィルス等の微生物がミスト濃度差によるストレスを確実に与えることができ、効率よく貯蔵室の庫壁や食品等の表面に付着したカビや細菌酵母およびウィルス等の微生物の増加を抑制することができるようになった。 As a result, microorganisms such as mold, bacterial yeast, and viruses attached to the surface of the storage room storage wall and food can reliably give stress due to the difference in mist concentration.

The amount of mist generated from the spray device can be suppressed.
 第30の発明は、断熱区画された複数の貯蔵室と、冷却器を収納し前記複数の貯蔵室と風路を介して繋がる冷却室と、ミストを噴霧する噴霧装置とを有し、前記複数の貯蔵室は、冷蔵温度帯で保持される冷蔵室と前記冷蔵温度帯と同等または高い温度設定とする野菜室とを少なくとも備え、前記貯蔵室内の収納部とは独立して前記ミストを貯留する専用区画を有するとともに、前記専用区画から前記冷蔵室への前記ミスト供給はファンを用いた強制対流とし、前記専用区画から前記野菜室への前記ミスト供給は自然対流とするミスト供給経路を備えた冷蔵庫。 A thirtieth aspect of the present invention includes a plurality of storage compartments that are partitioned by heat insulation, a cooling chamber that houses a cooler and is connected to the plurality of storage compartments via an air passage, and a spray device that sprays mist. The storage room includes at least a refrigeration room maintained in a refrigeration temperature zone and a vegetable room set to a temperature setting equal to or higher than the refrigeration temperature zone, and stores the mist independently of a storage unit in the storage room. In addition to having a dedicated section, the mist supply from the dedicated section to the refrigerator compartment is a forced convection using a fan, and the mist supply from the dedicated section to the vegetable room has a mist supply path for natural convection. refrigerator.
 これによって、貯蔵される食品が多岐にわたることで最も除菌もしくは消臭効果を発揮したい冷蔵室においては、前記専用区画から強制対流によってミストを供給することで濃いミストを供給することができ、さらに野菜室においては、前記専用区画から自然対流によってミストを供給することで強制対流を用いるよりもミストの濃度を薄くすることができ、ミストの配分の仕方を工夫することで必要に応じた任意の貯蔵室に合わせてミストの濃度調整がなされる冷蔵庫を提供することが可能となる。 As a result, in the refrigerator compartment where the sterilization or deodorization effect is most desired due to the wide variety of stored foods, it is possible to supply a thick mist by supplying mist from the dedicated compartment by forced convection. In the vegetable room, the mist concentration can be made thinner than using forced convection by supplying mist by natural convection from the dedicated section, and any method according to need can be obtained by devising the way of mist distribution. It is possible to provide a refrigerator in which the concentration of mist is adjusted according to the storage room.
 第31の発明は、断熱区画された複数の貯蔵室と、冷却器を収納し前記複数の貯蔵室と風路を介して繋がる冷却室と、ミストを噴霧する噴霧装置とを有し、前記複数の貯蔵室は、前記ミストを噴霧することによって主として除菌効果を期待する貯蔵室と、主として野菜の栄養素を増加させるもしくは野菜の低温障害を抑制する効果を期待する貯蔵室とを有し、前記除菌効果を期待する貯蔵室への前記ミスト供給はファンを用いた強制対流とし、前記野菜室への前記ミスト供給は自然対流とするミスト供給経路を備えた冷蔵庫。 A thirty-first invention has a plurality of storage compartments that are thermally insulated, a cooling chamber that houses a cooler and is connected to the plurality of storage compartments via an air passage, and a spray device that sprays mist. The storage room has a storage room that mainly expects a sterilizing effect by spraying the mist, and a storage room that mainly expects an effect of increasing the nutrients of vegetables or suppressing the low temperature damage of vegetables, The refrigerator provided with the mist supply path | route which makes the said mist supply to the storage room which expects a bactericidal effect the forced convection using a fan, and makes the said mist supply to the said vegetable room natural convection.
 これによって、貯蔵される食品が多岐にわたることで最も除菌もしくは消臭効果を発揮したい冷蔵室、または主として除菌効果を期待する貯蔵室においては、前記専用区画から強制対流によってミストを供給することで濃いミストを供給することができ、さらに野菜室または主に野菜を収納する貯蔵室においては、前記専用区画から自然対流によってミストを供給することで強制対流を用いるよりもミストの濃度を薄くすることができ、ミストの配分の仕方を工夫することで必要に応じた任意の貯蔵室に合わせてミストの濃度調整がなされる冷蔵庫を提供することが可能となる。 In this way, in a refrigerated room where sterilization or deodorization is most desired due to a wide variety of foods to be stored, or in storage rooms where sterilization is mainly expected, mist is supplied from the dedicated compartment by forced convection. In a vegetable room or a storage room that mainly stores vegetables, the mist concentration can be reduced by using natural convection from the dedicated compartment, compared to forced convection. It is possible to provide a refrigerator in which the concentration of mist is adjusted according to any storage room as required by devising the way of mist distribution.
 第32の発明は、前記ミスト供給経路は、前記野菜室または、主として野菜の栄養素を増加させるもしくは野菜の低温障害を抑制する効果を期待する貯蔵室と前記専用区画とを連通する開口部とを有し、前記開口部の大きさによってミスト供給量を調整するものである。 In a thirty-second aspect of the invention, the mist supply path includes an opening that communicates the vegetable compartment or a storage compartment that mainly increases the nutrients of the vegetable or expects an effect of suppressing low temperature damage of the vegetable and the dedicated compartment. And the mist supply amount is adjusted according to the size of the opening.
 これによって、開口部の大きさを変化させることでミスト供給量を調整することができるので、多機種の容量帯を持つ冷蔵庫の実機に適用した場合であっても、各貯蔵室の容量や噴霧装置の能力によって、開口部の面積を調整するという簡単な構成で効果的にミスト供給量を調整することが可能となる。 As a result, the amount of mist supplied can be adjusted by changing the size of the opening. Therefore, even when it is applied to a real machine of a refrigerator having a variety of capacity bands, the capacity and spray of each storage room Depending on the capability of the apparatus, the mist supply amount can be effectively adjusted with a simple configuration of adjusting the area of the opening.
 第33の発明は、前記噴霧装置が設けられた貯蔵室以外の貯蔵室におけるミスト濃度が、前記噴霧装置を設置した貯蔵室におけるミスト濃度よりも濃いものである。 In a thirty-third invention, the mist concentration in a storage chamber other than the storage chamber provided with the spraying device is higher than the mist concentration in the storage chamber in which the spraying device is installed.
 これによって、噴霧装置が設けられた貯蔵室以外の貯蔵室において、ミスト効果(除菌や脱臭など)を実現するために必要なミスト濃度が、噴霧装置を設置した貯蔵室よりも大きい場合であっても、噴霧装置は任意の最適な箇所へ設置した上で、濃いミスト濃度が必要な貯蔵室においてミスト効果を発現させることができる。 As a result, in a storage room other than the storage room provided with the spraying device, the mist concentration necessary for realizing the mist effect (such as sterilization and deodorization) is larger than that in the storage room where the spraying device is installed. However, the spraying device can be installed at any optimal location, and can exhibit a mist effect in a storage room that requires a high concentration of mist.
 第34の発明は、前記噴霧装置が設けられた貯蔵室以外の貯蔵室における絶対湿度が前記噴霧装置を設けた貯蔵室における絶対湿度よりも小さく、前記噴霧装置が設けられた貯蔵室以外の貯蔵室におけるミスト濃度が、前記噴霧装置を設置した貯蔵室におけるミスト濃度よりも大きいものである。 In a thirty-fourth aspect of the invention, the absolute humidity in a storage chamber other than the storage chamber provided with the spraying device is smaller than the absolute humidity in the storage chamber provided with the spraying device, and the storage other than the storage chamber provided with the spraying device. The mist concentration in the chamber is higher than the mist concentration in the storage chamber in which the spraying device is installed.
 これによって、相対的に絶対湿度が大きい貯蔵室に噴霧装置が設けられので、噴霧装置の霧化部において結露が発生しやすい状態となるので、安定的にミストを噴霧させることが可能となる。 As a result, since the spray device is provided in the storage chamber having a relatively high absolute humidity, it becomes possible for condensation to easily occur in the atomizing portion of the spray device, so that mist can be sprayed stably.
 また、相対的に絶対湿度が小さく噴霧装置が設置されない貯蔵室において、ミスト効果(除菌や脱臭など)を実現するために必要なミスト濃度が、噴霧装置を設置した貯蔵室よりも大きい場合であっても、噴霧装置が設けられた貯蔵室以外の貯蔵室においてミスト効果を発現させることができる。 In a storage room where the relative humidity is relatively low and the spraying device is not installed, the mist concentration required to achieve the mist effect (such as sterilization and deodorization) is higher than that in the storage room where the spraying device is installed. Even if it exists, a mist effect can be expressed in store rooms other than the store room provided with the spraying apparatus.
 つまり、噴霧装置が設置されない絶対湿度の小さい貯蔵室には、間接的にしかミストが噴霧されないので、噴霧装置を設置した貯蔵室よりも一般的にミスト濃度は低くなりやすいが、強制対流によって間接的にミスト噴霧されるその他貯蔵室のミスト濃度が高くなるのが本発明の要点である。 In other words, since the mist is sprayed only indirectly in a storage room with a low absolute humidity where no spray device is installed, the mist concentration generally tends to be lower than the storage room where the spray device is installed, but indirect by forced convection. The main point of the present invention is that the mist concentration of the other storage chambers to be sprayed with mist increases.
 第35の発明は、断熱材で構成され、内部に複数の貯蔵室を形成する断熱箱体と、前記断熱箱体の開口部に開閉自在に取り付けられる扉体と、前記断熱箱体内の空気を冷却し冷気を生成する冷却手段と、前記貯蔵室と前記冷却手段との間で前記冷気をファンにより循環させる風路と、貯蔵室の下流側に触媒を備え、前記貯蔵室内にOHラジカルを含んだミストを噴霧する霧化装置を配置したものである。 According to a thirty-fifth aspect of the present invention, a heat insulating box which is formed of a heat insulating material and forms a plurality of storage chambers therein, a door which is attached to an opening of the heat insulating box so as to be opened and closed, and air in the heat insulating box. Cooling means for cooling and generating cold air, an air passage for circulating the cold air between the storage chamber and the cooling means by a fan, a catalyst on the downstream side of the storage chamber, and containing OH radicals in the storage chamber An atomizing device for spraying mist is arranged.
 これによって、除菌・脱臭効果のあるOHラジカルを含んだミストが貯蔵室中に拡散され、直接空間内を除菌・脱臭し、さらに、OHラジカルを含んだミストが脱臭効果のある触媒に接触することで触媒の効果を高め、貯蔵室内の空気と循環している冷気の両方を効率的に除菌・脱臭することができる。 As a result, mist containing OH radicals with sterilizing and deodorizing effects is diffused into the storage room, sterilizing and deodorizing directly in the space, and mist containing OH radicals contacts the catalyst with deodorizing effects. By doing so, the effect of the catalyst can be enhanced, and both the air in the storage chamber and the circulating cold air can be sterilized and deodorized efficiently.
 第36の発明は、貯蔵室の下流側に設置した触媒は、マンガン系触媒からなるハニカム状活性炭で形成する脱臭フィルターであることを特徴としたものである。 The thirty-sixth aspect of the invention is characterized in that the catalyst installed on the downstream side of the storage chamber is a deodorizing filter formed of honeycomb-like activated carbon made of a manganese-based catalyst.
 これによって、ハニカム状の触媒内に、におい成分を含んだ冷気とOHラジカルを含んだミストを多量に効率よく通過させることができ、さらに、OHラジカルを含んだミストがマンガン系からなる触媒に多量に接触することで、触媒に吸着したにおい成分をOHラジカルにより分解されるため、触媒の効果を長期的に保ち、効率的に脱臭・除菌することができる。 As a result, a large amount of cool air containing odor components and mist containing OH radicals can be efficiently passed through the honeycomb-shaped catalyst, and a large amount of mist containing OH radicals is added to the manganese-based catalyst. Since the odor component adsorbed on the catalyst is decomposed by OH radicals by contacting with the catalyst, the effect of the catalyst can be maintained for a long period of time, and the deodorization and sterilization can be performed efficiently.
 第37の発明は、断熱材で構成され、内部に貯蔵室を形成する断熱箱体と、前記断熱箱体の開口部に開閉自在に取り付けられる扉体と、前記断熱箱体内の空気を冷却し冷気を生成する冷却手段と、前記貯蔵室と前記冷却手段との間で前記冷気をファンにより循環させる風路と、貯蔵室の下流側に触媒を備え、前記貯蔵室の冷気の上流側にOHラジカルを含んだミストを噴霧する霧化装置を設置したものである。 In a thirty-seventh aspect of the present invention, a heat insulating box body that is formed of a heat insulating material and forms a storage chamber therein, a door body that can be freely opened and closed to an opening of the heat insulating box body, and air in the heat insulating box body is cooled. A cooling means for generating cold air, an air passage for circulating the cold air between the storage chamber and the cooling means by a fan, a catalyst on the downstream side of the storage chamber, and an OH upstream of the cold air in the storage chamber An atomization device that sprays mist containing radicals is installed.
 これによって、OHラジカルを含んだミストを噴霧する霧化装置が貯蔵室の冷気の上流側にあることで、除菌・脱臭高価のあるOHラジカルを含んだミストは、貯蔵室内に拡散され、直接空間内を除菌・脱臭し、さらに、OHラジカルを含んだミストが脱臭効果のある触媒に接触することで触媒の効果を高め、貯蔵室内の空気と循環している冷気の両方を効率的に除菌・脱臭することができる。 As a result, the atomization device for spraying the mist containing OH radicals is located upstream of the cool air in the storage room, so that the mist containing OH radicals with high sterilization and deodorization is diffused into the storage room and directly The inside of the space is sterilized and deodorized, and the mist containing OH radicals comes into contact with the catalyst having a deodorizing effect, thereby enhancing the effect of the catalyst and efficiently both the air in the storage chamber and the circulating cold air. It can be sterilized and deodorized.
 第38の発明は、複数の貯蔵室を備えた冷蔵庫本体と、冷蔵庫の設置環境の変化を検知できる第1の検知手段と、前記冷蔵庫本体に備えられた電気負荷部品の動作を制御する制御手段とを有し、前記第1の検知手段で検知された出力信号により前記電気負荷部品の動作を抑制または停止する節電運転を自動的に行うとともに、前記節電運転を行う場合に前記制御手段によって貯蔵室内の温度が上昇する貯蔵室の下流側に触媒を備え、前記貯蔵室の冷気の上流側にOHラジカルを含んだミストを噴霧する霧化装置を設置したものである。 A thirty-eighth aspect of the invention is a refrigerator main body having a plurality of storage rooms, a first detection means capable of detecting a change in the installation environment of the refrigerator, and a control means for controlling the operation of the electrical load component provided in the refrigerator main body. And automatically performing a power saving operation for suppressing or stopping the operation of the electrical load component according to the output signal detected by the first detection means, and storing the power saving operation by the control means when performing the power saving operation. An atomizer for spraying mist containing OH radicals is installed on the upstream side of the cool air in the storage chamber, with a catalyst provided downstream of the storage chamber where the temperature in the room rises.
 これによって、温度が上昇する貯蔵室は貯蔵物から多量のにおい成分を放出しやすく、よりにおいが強い冷気になりやすいが、温度が上昇する貯蔵室に除菌脱臭効果のあるOHラジカルを含んだミストを噴霧させ、且つ、においの発生源である温度が高い貯蔵室の下流側に触媒を備えることで、貯蔵室内の空気と循環している冷気の両方を効率的に除菌・脱臭することができるため、脱臭効果を維持した上で、より省エネルギーを実現することが可能な冷蔵庫を提供することができる。 As a result, the storage room where the temperature rises easily releases a large amount of odorous components from the stored matter, and it tends to be cooler with a strong smell, but the storage room where the temperature rises contains OH radicals that have a sterilizing and deodorizing effect. Efficient sterilization and deodorization of both the air in the storage room and the circulating cold air by spraying mist and providing a catalyst on the downstream side of the storage room where the temperature that is the source of odor is high Therefore, it is possible to provide a refrigerator capable of realizing further energy saving while maintaining the deodorizing effect.

 図において、冷蔵庫100の冷蔵庫本体である断熱箱体101は、主に鋼板を用いた外箱102と、ABSなどの樹脂で成型された内箱103と、外箱102と内箱103との間の空間に発泡充填される硬質発泡ウレタン101bとで構成され、周囲と断熱され、仕切り壁101Cによって複数の貯蔵室に断熱区画されている。最上部に第三の貯蔵室としての冷蔵室104、その冷蔵室104の下部に第四の貯蔵室としての切替室105と第五の貯蔵室としての製氷室106が横並びに設けられ、その切替室105と製氷室106の下部に第二の貯蔵室としての冷凍室107、そして最下部に第一貯蔵室としての野菜室108が配置されており、それぞれの貯蔵室には扉104a、105a、106a、107a、118が設けられる構成となっている。 In the figure, a heat insulating box 101 which is a refrigerator main body of the refrigerator 100 includes an outer box 102 mainly using a steel plate, an inner box 103 formed of a resin such as ABS, and the outer box 102 and the inner box 103. It is comprised with the hard foaming urethane 101b by which foam filling is carried out, and it heat-insulates with the circumference | surroundings and is heat-insulated by the partition wall 101C into several storage chambers. A refrigeration chamber 104 as a third storage chamber is provided at the top, and a switching chamber 105 as a fourth storage chamber and an ice making chamber 106 as a fifth storage chamber are provided side by side at the lower portion of the refrigeration chamber 104. A freezing room 107 as a second storage room is arranged in the lower part of the chamber 105 and the ice making room 106, and a vegetable room 108 as a first storage room is arranged in the lowermost part, and doors 104a, 105a, 106a, 107a, and 118 are provided.
 冷蔵室104は冷蔵保存のために凍らない温度である冷蔵温度帯に設定されており、通常1℃~5℃とし、野菜室108は冷蔵室104と同等の冷蔵温度帯もしくは若干高い温度設定の野菜温度帯2℃~7℃としている。冷凍室107は冷凍温度帯に設定されており、冷凍保存のために通常-22℃~-15℃で設定されているが、冷凍保存状態の向上のために、例えば-30℃や-25℃の低温で設定されることもある。 The refrigerated room 104 is set in a refrigerated temperature zone, which is a temperature that does not freeze for refrigerated storage. Usually, the temperature is set to 1 ° C. to 5 ° C. The vegetable temperature range is 2 ° C to 7 ° C. The freezer compartment 107 is set in a freezing temperature zone and is usually set at −22 ° C. to −15 ° C. for frozen storage, but for example, −30 ° C. or −25 ° C. to improve the frozen storage state. It may be set at a low temperature.
 切替室105は、冷蔵温度帯、野菜温度帯、冷凍温度帯以外に、冷蔵温度帯から冷凍温度帯の間で予め設定された温度帯に切り換えることができる。切替室105は製氷室106に並設された独立扉を備えた貯蔵室であり、引き出し式の扉を備えることが多い。 The switching chamber 105 can be switched to a preset temperature zone between the refrigeration temperature zone and the freezing temperature zone in addition to the refrigeration temperature zone, vegetable temperature zone, and freezing temperature zone. The switching chamber 105 is a storage chamber provided with an independent door arranged in parallel with the ice making chamber 106, and is often provided with a drawer-type door.
 なお、本実施の形態では、切替室105を、冷蔵と冷凍の温度帯までを含めた貯蔵室としているが、冷蔵は冷蔵室104と野菜室108、冷凍は冷凍室107に委ねて、冷蔵と冷凍の中間の上記温度帯のみの切り換えに特化した貯蔵室としても構わない。また、特定の温度帯に固定された貯蔵室でも構わない。 In this embodiment, the switching chamber 105 is a storage room including the temperature range of refrigeration and freezing. However, the refrigeration is performed by the refrigeration room 104 and the vegetable room 108, and the freezing is performed by the freezing room 107. A storage room specialized for switching only the temperature zone in the middle of freezing may be used. Moreover, the storage room fixed to the specific temperature range may be sufficient.
 製氷室106は、冷蔵室104内の貯水タンク(図示せず)から送られた水で室内上部に設けられた自動製氷機(図示せず)で氷を作り、室内下部に配置した貯氷容器(図示せず)に貯蔵する。 The ice making chamber 106 creates ice with an automatic ice maker (not shown) provided in the upper part of the room with water sent from a water storage tank (not shown) in the refrigerated room 104, and an ice storage container ( (Not shown).
 断熱箱体101の天面部は冷蔵庫の背面方向に向かって階段状に凹みを設けた形状であり、この階段状の凹部に機械室101aを形成して、機械室101aに、圧縮機109、水分除去を行うドライヤ(図示せず)等の冷凍サイクルの高圧側構成部品が収容されている。すなわち、圧縮機109を配設する機械室101aは、冷蔵室104内の最上部の後方領域に食い込んで形成されることになる。 The top surface portion of the heat insulating box 101 has a stepped recess shape toward the back of the refrigerator. A machine chamber 101a is formed in the stepped recess, and the compressor 109, moisture is formed in the machine chamber 101a. Houses high pressure side components of the refrigeration cycle such as a dryer (not shown) for removal. That is, the machine room 101 a in which the compressor 109 is disposed is formed by biting into the uppermost rear region in the refrigerator compartment 104.
 このように、手が届きにくくデッドスペースとなっていた断熱箱体101の最上部の貯蔵室後方領域に機械室101aを設けて圧縮機109を配置することにより、従来の冷蔵庫で、使用者が使いやすい断熱箱体101の最下部にあった機械室のスペースを貯蔵室容量として有効に転化することができ、収納性や使い勝手を大きく改善することができる。 Thus, by providing the machine room 101a in the rear region of the uppermost storage room of the heat insulation box 101 that has become a dead space that is difficult to reach, the compressor 109 is disposed in the conventional refrigerator. The space in the machine room at the bottom of the easy-to-use heat insulation box 101 can be effectively converted as the storage room capacity, and the storage performance and usability can be greatly improved.
 冷凍サイクルは、圧縮機109と凝縮器(図示せず)と減圧器であるキャピラリーと冷却器112とアキュムレーター112aを冷媒配管112bによって順に備えた一連の冷媒流路から形成されており、冷媒として炭化水素系冷媒である例えばイソブタンが封入されている。 The refrigeration cycle is formed of a series of refrigerant flow paths including a compressor 109, a condenser (not shown), a capillary as a decompressor, a cooler 112, and an accumulator 112a in order by a refrigerant pipe 112b. For example, isobutane, which is a hydrocarbon-based refrigerant, is enclosed.
 圧縮機109はピストンがシリンダ内を往復動することで冷媒の圧縮を行う往復動型圧縮機である。断熱箱体101に、三方弁や切替弁を用いる冷凍サイクルの場合は、それらの機能部品が機械室101a内に配設されている場合もある。 Compressor 109 is a reciprocating compressor that compresses refrigerant by reciprocating a piston in a cylinder. In the case of a refrigeration cycle using a three-way valve or a switching valve for the heat insulation box 101, those functional parts may be disposed in the machine room 101a.
 また、本実施の形態では冷凍サイクルを構成する減圧器をキャピラリーとしたが、パルスモーターで駆動する冷媒の流量を自由に制御できる電子膨張弁を用いてもよい。 In the present embodiment, the decompressor constituting the refrigeration cycle is a capillary, but an electronic expansion valve that can freely control the flow rate of the refrigerant driven by the pulse motor may be used.
 なお、本実施の形態における、以下に述べる発明の要部に関する事項は、従来一般的であった断熱箱体101の最下部の貯蔵室後方領域に機械室を設けて圧縮機109を配置するタイプの冷蔵庫に適用しても構わない。 In the present embodiment, the matter relating to the main part of the invention described below is a type in which a compressor room is provided by providing a machine room in the rear region of the lowermost storage room of the heat insulating box 101, which has been generally used conventionally. It may be applied to other refrigerators.
 冷凍室107の背面には冷気を生成する冷却室110が設けられ、風路141と区画されており、各貯蔵室と断熱区画するために構成された奥面仕切り壁111が構成されている。冷却室110内には、冷却器112が配設されており、冷却器112の上部空間には強制対流方式により冷却器112で冷却した冷気を冷蔵室104、切替室105、製氷室106、野菜室108、冷凍室107に送風するファン113が配置される。 A cooling chamber 110 for generating cold air is provided on the back surface of the freezing chamber 107 and is partitioned from the air passage 141, and a rear partition wall 111 configured to be thermally insulated from each storage chamber is configured. In the cooling chamber 110, a cooler 112 is disposed, and in the upper space of the cooler 112, the cold air cooled by the cooler 112 by a forced convection method is stored in the refrigerating chamber 104, the switching chamber 105, the ice making chamber 106, and vegetables. A fan 113 for blowing air to the chamber 108 and the freezing chamber 107 is disposed.
 風路141にはダンパ装置141a(241)が設けられ風路内の風量調整を行なうもので、本実施の形態では冷蔵室104への風量調整により室内の温度を所定の温度範囲となるようにしている。 The air passage 141 is provided with a damper device 141a (241) for adjusting the air flow in the air passage. In this embodiment, the air temperature to the refrigerator compartment 104 is adjusted so that the room temperature falls within a predetermined temperature range. ing.
 また、冷却器112の下部空間には冷却時に冷却器112やその周辺に付着する霜や氷を除霜するためのガラス管製のラジアントヒータ114が設けられている。 Further, a radiant heater 114 made of a glass tube is provided in the lower space of the cooler 112 for defrosting the frost and ice adhering to the cooler 112 and its surroundings during cooling.
 野菜室108には、野菜室108の引き出し扉118に取り付けられたフレームに載置された収納容器119が配置されている。 In the vegetable compartment 108, a storage container 119 placed on a frame attached to the drawer door 118 of the vegetable compartment 108 is arranged.
 野菜室108の上部には、野菜室108内を冷却し熱交換された冷気が冷却器112に戻るための野菜室用の吸込み口126と野菜室108の上部に設置される吸込み口カバー126aが吸込み口126を覆うように設けられている。なお、熱交換された冷気は吸込み口カバー126aに設けた開口部から取り込まれ吸込み口126を通り、冷却室110まで運ばれて、冷却されたのち冷蔵庫内を循環していく。 In the upper part of the vegetable compartment 108, there are a suction inlet 126 for the vegetable compartment for cooling the inside of the vegetable compartment 108 and returning heat to the cooler 112, and a suction inlet cover 126a installed in the upper part of the vegetable compartment 108. It is provided so as to cover the suction port 126. The heat-exchanged cold air is taken in from an opening provided in the suction port cover 126a, is carried to the cooling chamber 110 through the suction port 126, and is circulated in the refrigerator after being cooled.
 なお、本実施の形態における、以下に述べる発明の要部に関する事項は、従来一般的であった扉に取り付けられたフレームと内箱に設けられたレールにより開閉するタイプの冷蔵庫に適用しても構わない。 It should be noted that the matters relating to the main part of the invention described below in the present embodiment may be applied to a refrigerator that is opened and closed by a frame attached to a door and a rail provided in an inner box, which has been conventionally common. I do not care.
 奥面仕切り壁111は、ABSなどの樹脂と、風路141や冷却室110を隔離し、貯蔵室の断熱性を確保するための発泡スチロールなどの断熱材とで構成されている。 The rear partition wall 111 is made of a resin such as ABS and a heat insulating material such as polystyrene foam for isolating the air passage 141 and the cooling chamber 110 and ensuring the heat insulation of the storage chamber.
 野菜室108の上部には外郭ケース127が設けられており、その内部に噴霧装置131が設置されている。 The outer case 127 is provided in the upper part of the vegetable compartment 108, and the spraying device 131 is installed in the inside.
 霧化部139は、その先端からミストを噴霧する霧化電極であって白金やチタンなどで構成されている。霧化部139は、アルミニウムやステンレスなどの良熱伝導部材からなる伝熱冷却部材である冷却ピン134とアルミナなどの電気絶縁材料を介して近接し、冷却ピン134のほぼ中心部に位置するように固定されている。 The atomization unit 139 is an atomization electrode that sprays mist from its tip, and is made of platinum, titanium, or the like. The atomizing section 139 is located close to the cooling pin 134, which is a heat transfer cooling member made of a good heat conducting member such as aluminum or stainless steel, via an electrically insulating material such as alumina, and is located almost at the center of the cooling pin 134. It is fixed to.
 また、冷却ピン134の素材はアルミや銅などの高熱伝導部材が好ましく、冷却ピン134の一端からもう一端に冷熱を熱伝導で効率よく伝導させるため、その周囲は断熱材152で覆われていることが望ましい。 The material of the cooling pin 134 is preferably a high heat conductive member such as aluminum or copper, and the periphery of the cooling pin 134 is covered with a heat insulating material 152 in order to efficiently transfer cold heat from one end to the other end of the cooling pin 134. It is desirable.
 冷却ピン134は断熱材152の内部に位置しており、本実施の形態ではその先端を冷凍室107側に露出させている。 The cooling pin 134 is located inside the heat insulating material 152, and the tip thereof is exposed to the freezer compartment 107 side in this embodiment.
 冷凍室107の温度は-22℃~-15℃であり、冷却ピン134の先端を露出することで、より効果的に冷却ピン134の全体を冷却することができる。あるいは、冷却ピン134の先端表面だけを冷凍室107に露出させるだけでも良い。さらには、冷却ピン134を断熱材152の中に埋め込んだ状態でも良いが、この場合は冷却ピン134の冷却効果が本実施の形態の場合よりも小さくなる。 The temperature of the freezer compartment 107 is −22 ° C. to −15 ° C., and the entire cooling pin 134 can be cooled more effectively by exposing the tip of the cooling pin 134. Alternatively, only the tip surface of the cooling pin 134 may be exposed to the freezer compartment 107. Furthermore, the cooling pin 134 may be embedded in the heat insulating material 152, but in this case, the cooling effect of the cooling pin 134 is smaller than that in the present embodiment.
 ここで、冷凍室107の冷気によって冷却された冷却ピン134は熱伝導によって霧化部139を冷却し、露点以下の温度となった霧化部139の表面に結露が生じ、この結露水を用いてミストが噴霧されることとなる。 Here, the cooling pin 134 cooled by the cold air in the freezer compartment 107 cools the atomizing portion 139 by heat conduction, and condensation occurs on the surface of the atomizing portion 139 that has become a temperature below the dew point, and this condensed water is used. Mist will be sprayed.
 また、霧化部139に対向している位置で貯蔵室(野菜室108)側にドーナツ円盤状の対向電極136が、霧化部139の先端と一定距離を保つように取付けられている。 In addition, a donut disk-shaped counter electrode 136 is attached to the storage chamber (vegetable chamber 108) side at a position facing the atomizing portion 139 so as to maintain a certain distance from the tip of the atomizing portion 139.
 さらに、霧化部139の近傍に電圧印加部133が構成され、高電圧を発生する電圧印加部133の負電位側が霧化電極135と、正電位側が対向電極136とそれぞれ電気的に接続されている。 Further, a voltage application unit 133 is configured in the vicinity of the atomization unit 139, and the negative potential side of the voltage application unit 133 that generates a high voltage is electrically connected to the atomization electrode 135 and the positive potential side is electrically connected to the counter electrode 136, respectively. Yes.
 霧化部139近傍では、ミスト噴霧のため、常に放電が起こるため、霧化部139先端では、磨耗を生じる可能性がある。冷蔵庫100は、一般に10年以上の長期間にわたって運転することになるので、霧化部139の表面には表面処理が必要であり、例えば、ニッケルメッキ、および金メッキや白金メッキを用いることが望ましい。 In the vicinity of the atomizing portion 139, discharge is always generated due to mist spraying, and thus there is a possibility that wear will occur at the tip of the atomizing portion 139. Since the refrigerator 100 is generally operated for a long period of 10 years or longer, the surface of the atomizing portion 139 needs to be surface-treated. For example, it is desirable to use nickel plating, gold plating, or platinum plating.
 対向電極136は、例えば、ステンレスで構成されていて、また、その長期信頼性を確保する必要があり、特に異物付着防止、汚れ防止するため、例えば白金メッキなどの表面処理をすることが望ましい。 The counter electrode 136 is made of, for example, stainless steel, and it is necessary to ensure its long-term reliability. In particular, in order to prevent foreign matter adhesion and contamination, it is desirable to perform surface treatment such as platinum plating.
 電圧印加部133は、冷蔵庫本体の制御手段146と通信、制御され、冷蔵庫100もしくは噴霧装置131からの入力信号で高電圧印加のON/OFFを行う。 The voltage application unit 133 communicates and is controlled with the control means 146 of the refrigerator main body, and performs ON / OFF of high voltage application by an input signal from the refrigerator 100 or the spray device 131.
 以上のように構成された本実施の形態の冷蔵庫100について、以下その動作、作用を説明する。 The operation and action of the refrigerator 100 of the present embodiment configured as described above will be described below.
 まず、冷凍サイクルの動作について説明する。庫内の設定された温度に応じて制御基板(図示せず)からの信号により冷凍サイクルが動作して冷却運転が行われる。圧縮機109の動作により吐出された高温高圧の冷媒は、凝縮器(図示せず)である程度凝縮液化し、さらに冷蔵庫本体である断熱箱体101の側面や背面、また断熱箱体101の前面間口に配設された冷媒配管112bなどを経由し断熱箱体101の結露を防止しながら凝縮液化し、キャピラリーチューブ(図示せず)に至る。その後、キャピラリーチューブでは圧縮機109への吸入管(図示せず)と熱交換しながら減圧されて低温低圧の液冷媒となって冷却器112に至る。 First, the operation of the refrigeration cycle will be described. The refrigeration cycle is operated by a signal from a control board (not shown) according to the set temperature in the cabinet, and the cooling operation is performed. The high-temperature and high-pressure refrigerant discharged by the operation of the compressor 109 is condensed to some extent by a condenser (not shown), and further, the side surface and the rear surface of the heat insulation box body 101 which is the refrigerator main body, and the front opening of the heat insulation box body 101. The refrigerant is condensed and liquefied while preventing condensation of the heat insulating box 101 through the refrigerant pipe 112b and the like, and reaches a capillary tube (not shown). After that, the capillary tube is depressurized while exchanging heat with a suction pipe (not shown) to the compressor 109 to become a low-temperature and low-pressure liquid refrigerant and reaches the cooler 112.
 ここで低温低圧の液冷媒は各貯蔵室内の冷気と熱交換され、冷却器112内の冷媒は蒸発気化する。蒸発気化時には周囲から気化熱を奪うことで、冷却室110内で各貯蔵室を冷却するための冷気を生成する。低温冷気はファン203から冷蔵室104、切替室105、製氷室106、野菜室108、冷凍室107に冷気を風路141やダンパ装置141b(241)を用いて分流させ、それぞれの目的温度帯に冷却する。特に、野菜室108は、冷気の配分や加熱手段(図示せず)などのON/OFF運転により2℃から7℃になるように調整され、一般的には庫内温度検知手段を持たないものが多い。 Here, the low-temperature and low-pressure liquid refrigerant exchanges heat with the cold air in each storage chamber, and the refrigerant in the cooler 112 evaporates. When evaporating and evaporating, heat for evaporating is taken from the surroundings to generate cool air for cooling each storage chamber in the cooling chamber 110. The low-temperature cold air is diverted from the fan 203 to the refrigerating room 104, the switching room 105, the ice making room 106, the vegetable room 108, and the freezing room 107 by using the air passage 141 and the damper device 141b (241), and is brought to the respective target temperature zones. Cooling. In particular, the vegetable compartment 108 is adjusted to 2 ° C. to 7 ° C. by ON / OFF operation such as cold air distribution and heating means (not shown), and generally has no internal temperature detection means. There are many.
 冷蔵庫100の各貯蔵室を循環する冷気の流れを図3により説明する。各貯蔵室の冷気は、ファン203が作動することで風路141を通じて冷却室110へ戻ってくる構造となっている。戻ってきた冷気は冷却器112を通過するときに熱交換されて冷却されて、風路を通じて各貯蔵室へと供給される。 The flow of the cold air circulating through each storage room of the refrigerator 100 will be described with reference to FIG. The cool air in each storage chamber is structured to return to the cooling chamber 110 through the air passage 141 when the fan 203 is operated. When the returned cold air passes through the cooler 112, it is heat-exchanged and cooled, and is supplied to each storage room through an air passage.
 まず冷却室110で熱交換された冷気は、冷凍室107、切替室105、製氷室106へ供給されるとともに、ダンパ装置141bが開いている時には、冷蔵室104へ供給される。また、ダンパ装置141bを通過した冷気は冷蔵室104内へ向かう風路141と枝分かれした野菜室108へ通じる風路141を通じて、野菜室108へと供給される。 First, the cold air exchanged in the cooling chamber 110 is supplied to the freezing chamber 107, the switching chamber 105, and the ice making chamber 106, and is also supplied to the refrigerating chamber 104 when the damper device 141b is open. The cold air that has passed through the damper device 141b is supplied to the vegetable compartment 108 through the air passage 141 that leads into the refrigerator compartment 104 and the air passage 141 that leads to the branched vegetable compartment 108.
 なお、各貯蔵室の冷気は再び、風路141を通じて冷却室110へと戻ることとなり、このサイクルを繰り返すことで冷蔵庫を所定の温度に冷却する。 The cold air in each storage room returns to the cooling room 110 through the air passage 141 again, and the refrigerator is cooled to a predetermined temperature by repeating this cycle.
 ここで野菜室108を循環した冷気は、吸込み口126を通じて冷却室110へと戻るが、図4、図5に示す通り、噴霧装置131は外郭ケース127に収納されており、外郭ケース127には野菜室108の高湿冷気を取り込むための開口部である水分供給口138が設けられている。取り込まれた高湿冷気は露点以下となった霧化部139で冷却されて、結露してミストが噴霧される。この時、ファン203が作動しているときは、外郭ケース127は吸込み口126と連結しているので、吸込み口126、風路141を通じて冷却室110へミストが運ばれて冷蔵庫100の各貯蔵室に供給される。 Here, the cold air circulated through the vegetable chamber 108 returns to the cooling chamber 110 through the suction port 126, but as shown in FIGS. 4 and 5, the spray device 131 is accommodated in the outer case 127. A moisture supply port 138 that is an opening for taking in the high humidity and cold air of the vegetable compartment 108 is provided. The taken-in high-humidity cold air is cooled by the atomizing section 139 that has become below the dew point, and is condensed to spray mist. At this time, when the fan 203 is operating, the outer case 127 is connected to the suction port 126, so that the mist is conveyed to the cooling chamber 110 through the suction port 126 and the air passage 141, and each storage chamber of the refrigerator 100. To be supplied.
 また、吸込み口カバー126aは吸込み口126と連結しており、野菜室108の冷気を開口部147から取り入れて、吸込み口126、風路141を通じて冷却室110へ運ぶようになっている。 Further, the suction port cover 126a is connected to the suction port 126 so that the cool air of the vegetable chamber 108 is taken in from the opening 147 and is conveyed to the cooling chamber 110 through the suction port 126 and the air passage 141.
 ここで、本実施の形態では外郭ケース127と吸込み口カバー126aとは連結されている。なお、外郭ケース127が吸込み口カバー126aを兼用されることもあり、その場合、水分供給口138が開口部147の役割も兼用することとなる。 Here, in this embodiment, the outer case 127 and the suction port cover 126a are connected. Note that the outer case 127 may also serve as the suction port cover 126a. In this case, the moisture supply port 138 also serves as the opening 147.
 冷却ピン134の先端にある冷却手段である冷凍室107には、冷却システムの運転により冷却器112で生成し、ファン113により-15~-25℃程度の冷気が流れ、伝熱冷却部材である冷却ピン134が例えば0~-10℃程度に冷却される。 The freezing chamber 107, which is a cooling means at the tip of the cooling pin 134, is generated by the cooler 112 by the operation of the cooling system, and cool air of about −15 to −25 ° C. flows by the fan 113 and is a heat transfer cooling member. The cooling pin 134 is cooled to about 0 to −10 ° C., for example.
 このとき、冷却ピン134は、良熱伝導部材であるため、冷熱を非常に伝えやすく、冷却ピン134を介して霧化部139も0~-10℃程度に間接的に冷却される。 At this time, since the cooling pin 134 is a good heat conduction member, it is very easy to transmit cold heat, and the atomizing portion 139 is also indirectly cooled to about 0 to −10 ° C. via the cooling pin 134.
 ここで、野菜室108の温度は2℃から7℃で、かつ野菜などからの蒸散により比較的高湿状態であるので霧化部139は露点以下となれば、霧化部139には水が生成し、水滴が付着する。 Here, the temperature of the vegetable compartment 108 is 2 ° C. to 7 ° C., and it is in a relatively high humidity state due to transpiration from vegetables, so that if the atomizing portion 139 is below the dew point, the atomizing portion 139 has water. Generated and water droplets adhere.
 また、霧化部139を直接冷却することなく、伝熱冷却部材である冷却ピン134を冷却することで間接的に霧化部139を冷却することができ、伝熱冷却部材である冷却ピン134が霧化部139よりも大きな熱容量を有するようにすることで、霧化部139に直接的に大きな影響を与えることを緩和し、霧化部139を冷却することができ、また、蓄冷の役割を果たすことにより霧化部139の急激な温度変動を抑え、安定した噴霧量のミスト噴霧を実現することができる。 Moreover, the atomization part 139 can be cooled indirectly by cooling the cooling pin 134 which is a heat-transfer cooling member, without directly cooling the atomization part 139, and the cooling pin 134 which is a heat-transfer cooling member Has a larger heat capacity than that of the atomizing section 139, so that the direct influence on the atomizing section 139 can be reduced, and the atomizing section 139 can be cooled. By fulfilling the above, it is possible to suppress a rapid temperature fluctuation of the atomizing section 139 and realize a mist spray with a stable spray amount.
 このように、霧化部139に対向する位置に対向電極136を備え、霧化部139と対向電極136間に高圧電位差を発生させる電圧印加部133を有することで、霧化部139近傍の電界が安定に構築できることによって微粒化現象、噴霧方向が定まり、外郭ケース127内に噴霧する微細ミストの精度をより高めることができ、信頼性が高い噴霧装置131を提供することができる。 Thus, the electric field in the vicinity of the atomization unit 139 is provided by providing the counter electrode 136 at a position facing the atomization unit 139 and having the voltage application unit 133 that generates a high-voltage potential difference between the atomization unit 139 and the counter electrode 136. Can be stably constructed, the atomization phenomenon and the spray direction are determined, the accuracy of the fine mist sprayed in the outer case 127 can be further increased, and the spray device 131 with high reliability can be provided.
 さらに、伝熱冷却部材である冷却ピン134は熱緩和部材(断熱材152)を介して冷却されるので、前記のように霧化部139を冷却ピン134で間接的に冷却するものにさらに、熱緩和部材である断熱材152を介して二重構造で間接的に冷却することができ、霧化部139が極度に冷却されることを防ぐことができる。 Furthermore, since the cooling pin 134 which is a heat transfer cooling member is cooled via the heat relaxation member (heat insulating material 152), in addition to the one that indirectly cools the atomizing portion 139 with the cooling pin 134 as described above, It can cool indirectly with the double structure through the heat insulating material 152 which is a heat relaxation member, and can prevent that the atomization part 139 is cooled extremely.
 噴霧装置131は外郭ケース127に設けられた水分供給口138より、高湿冷気を取り入れ、霧化部139で結露することでミストを噴霧することができる。 The spraying device 131 can spray high-humidity cold air from the water supply port 138 provided in the outer case 127 and spray the mist by condensing in the atomizing unit 139.
 霧化電極135で発生した微細ミストは、外郭ケース127内に噴霧されるが、非常に小さい微粒子のため拡散性が強く、水分供給口138を通じて野菜室108にも微細ミストが拡散する。噴霧される微細ミストは、高圧放電で生成されたため、マイナスの電荷を帯びている。一方、野菜室108内には青果物である野菜の中でも緑の菜っ葉ものや果物等も保存されており、これらの青果物は蒸散あるいは保存中の蒸散によってより萎れやすいものである。野菜室内に保存されている野菜や果物の中には、通常、購入帰路時での蒸散あるいは保存中の蒸散によってやや萎れかけた状態のものが含まれており、プラスの電荷をもつ。よって、霧化されたミストは、野菜の表面に集まりやすく、これにより保鮮性が向上する。 The fine mist generated in the atomizing electrode 135 is sprayed in the outer case 127, but is very diffusible due to very small fine particles, and the fine mist diffuses into the vegetable compartment 108 through the water supply port 138. Since the fine mist to be sprayed is generated by high-pressure discharge, it has a negative charge. On the other hand, among the vegetables which are fruits and vegetables, green vegetable leaves and fruits are also stored in the vegetable room 108, and these fruits and vegetables are more susceptible to wilt due to transpiration or transpiration during storage. Some vegetables and fruits stored in the vegetable compartment usually have a slight charge due to transpiration at the time of purchase return or transpiration during storage, and have a positive charge. Therefore, the atomized mist is easy to gather on the surface of vegetables, and this improves the freshness.
 また、野菜表面に付着したナノレベルの微細ミストは、OHラジカルと微量ではあるがオゾンなどを多く含んでおり、殺菌、抗菌、除菌などに効果がある他、酸化分解による農薬除去や抗酸化によるビタミンC量などの栄養素の増加を野菜に促す。 In addition, nano-level fine mist adhering to the vegetable surface contains a lot of OH radicals and a small amount of ozone, etc., and is effective for sterilization, antibacterial, sterilization, etc. Encourages vegetables to increase nutrients such as vitamin C.
 ここで、霧化部139に水がないときは、放電距離が離れ、冷気の絶縁層を破壊することができず、放電現象が起こらない。これにより霧化部139と対向電極136間に電流が流れない。この現象を冷蔵庫100の制御手段146で検知することにより電圧印加部133の高圧をON/OFFすることもできる。 Here, when there is no water in the atomizing part 139, the discharge distance is increased, the cold insulating layer cannot be destroyed, and the discharge phenomenon does not occur. As a result, no current flows between the atomizing portion 139 and the counter electrode 136. By detecting this phenomenon by the control means 146 of the refrigerator 100, the high voltage of the voltage application unit 133 can be turned ON / OFF.
 また、本実施の形態において、電圧印加部133はポッチング材やコーティング材よる防湿・防水構造をとることにより回路の保護を行っている。 In this embodiment, the voltage application unit 133 protects the circuit by adopting a moisture-proof / water-proof structure using a potting material or a coating material.
 なお、電圧印加部133を貯蔵室外に設置する場合は、上記対応を行わなくてもよい。 In addition, when installing the voltage application part 133 outside a storage room, it is not necessary to perform the said response | compatibility.
 噴霧装置131からミストを噴霧するタイミングは図6によって説明する。まず、冷蔵庫100においてファン203は冷却室110で生成する冷気を全貯蔵室へ供給するために定期的にON/OFFをしており、ON時にファン203が動作し、OFF時にファン203は停止している状態となる。 The timing of spraying mist from the spray device 131 will be described with reference to FIG. First, in the refrigerator 100, the fan 203 is periodically turned on / off in order to supply the cool air generated in the cooling chamber 110 to all the storage rooms. The fan 203 operates when it is on, and the fan 203 stops when it is off. It will be in the state.
 また、ダンパ装置141bは冷蔵室104、野菜室108へ冷却室110で生成する冷気を分配するために定期的に開閉しており、冷蔵室104、野菜室108の温度が所定よりも高い時に開いて冷気を供給し、冷蔵室104、野菜室108の温度が所定よりも低い時に閉じて過冷状態となるのを防ぐ。 The damper device 141b is periodically opened and closed to distribute the cold air generated in the cooling chamber 110 to the refrigerator compartment 104 and the vegetable compartment 108, and opens when the temperature of the refrigerator compartment 104 and the vegetable compartment 108 is higher than a predetermined value. Then, cold air is supplied, and when the temperature of the refrigerator compartment 104 and the vegetable compartment 108 is lower than a predetermined temperature, it is closed and prevented from being overcooled.
 高圧印加部133も定期的にON/OFFを繰り返し、ON時に霧化部139と対向電極136との間に高電圧が印加されミストが噴霧され、OFF時は高電圧が印加されないのでミストが噴霧されることがない。 The high voltage application unit 133 also periodically repeats ON / OFF. When ON, a high voltage is applied between the atomizing unit 139 and the counter electrode 136 and mist is sprayed, and when it is OFF, no high voltage is applied and the mist is sprayed. It will not be done.
 ここで本実施の形態1では、ファン203が動作する時に高電圧が印加される時(噴霧2)があり、この時に発生したミストが吸込み口126を通じて冷却室110へと取り込まれるとともに冷凍室107、切替室105、製氷室106へとミストが供給される。またこの時、ダンパ装置141bも開いているので、冷蔵室104や野菜室108へと風路141を通じてミストが供給される。 Here, in the first embodiment, there is a time when a high voltage is applied (spray 2) when the fan 203 operates, and the mist generated at this time is taken into the cooling chamber 110 through the suction port 126 and the freezing chamber 107. The mist is supplied to the switching chamber 105 and the ice making chamber 106. At this time, the damper device 141b is also open, so that mist is supplied to the refrigerator compartment 104 and the vegetable compartment 108 through the air passage 141.
 また、ファン203が動作しない時にも高電圧が印加される時(噴霧1)があり、このとき、ミストは吸込み口126を通過することはなく、外郭ケース127内に滞留することなく拡散し、水分供給口138や吸込み口カバー126aの開口部147を通じて野菜室108内に供給される。 Further, there is a time when a high voltage is applied even when the fan 203 does not operate (spray 1). At this time, the mist does not pass through the suction port 126 and diffuses without staying in the outer case 127, It is supplied into the vegetable compartment 108 through the moisture supply port 138 and the opening 147 of the suction port cover 126a.
 以上のように、本実施の形態1においては、断熱区画された複数の貯蔵室(野菜室108等)と、冷却器112とファン203とを収納し各貯蔵室と風路141により繋がる冷却室110と、ミストを噴霧させる霧化部139と霧化部139に接続された伝熱冷却部材(冷却ピン134)とで構成される噴霧装置131と、冷却ピン134を冷却する冷却手段とを有し、冷却手段が冷却ピン134を冷却することで間接的に霧化部139を露点以下に冷却し、霧化部139に冷気中の水分を結露させて各貯蔵室にミストとして噴霧する冷蔵庫であって、噴霧装置131は野菜室108内に設けられた外郭ケース127内に収納されており、外郭ケース127は野菜室108から冷却室110へ室内冷気を戻す吸込み口126と連結されており、外郭ケース127における野菜室108に対する面に開口部である水分供給口138が設けられており、少なくともファン203が動作するとき、噴霧装置131によりミストが噴霧されるときがあるものであり、噴霧装置131から発生するミストは、まず外郭ケース127内に拡散するので、噴霧装置131が設けられた野菜室108に直接に全量が供給されることがない。さらに、外郭ケース127は野菜室108の吸込み口126に連結されているため、ミストがその他の貯蔵室へ拡散できる経路が形成されるとともに、ミストはファン203が動作するときに噴霧されているので、ファン203による強制対流を利用して、他の貯蔵室へミストが自ずと供給される構成が冷蔵庫100において実現できる。 As described above, in the first embodiment, a plurality of storage compartments (such as the vegetable compartment 108) that are thermally insulated, the cooler 112, and the fan 203 are accommodated and connected to each storage compartment by the air passage 141. 110, an atomizing unit 139 for spraying mist, and a heat transfer cooling member (cooling pin 134) connected to the atomizing unit 139, and a cooling means for cooling the cooling pin 134. In the refrigerator, the cooling means cools the cooling pin 134 to indirectly cool the atomization unit 139 to a dew point or less, and moisture in the cold air is condensed on the atomization unit 139 and sprayed as mist in each storage chamber. The spray device 131 is housed in an outer case 127 provided in the vegetable compartment 108, and the outer case 127 is connected to a suction port 126 that returns indoor cold air from the vegetable compartment 108 to the cooling chamber 110. A water supply port 138 that is an opening is provided on the surface of the outer case 127 with respect to the vegetable compartment 108, and at least when the fan 203 operates, mist may be sprayed by the spray device 131. Since the mist generated from the device 131 is first diffused into the outer case 127, the entire amount is not directly supplied to the vegetable compartment 108 provided with the spraying device 131. Further, since the outer case 127 is connected to the suction port 126 of the vegetable compartment 108, a path through which the mist can diffuse to other storage compartments is formed, and the mist is sprayed when the fan 203 operates. A configuration in which mist is naturally supplied to another storage room using forced convection by the fan 203 can be realized in the refrigerator 100.
 なお、噴霧装置131が設けられた野菜室108へのミストの供給は、外郭ケース127に設けられた水分供給口138を通じて、主にファン203が動作しないときに行われる。
る。
The supply of mist to the vegetable compartment 108 provided with the spray device 131 is performed mainly when the fan 203 does not operate through the moisture supply port 138 provided in the outer case 127.
The
 また、噴霧装置131は外郭ケース127内に取り付けられていることで容易に人の手に触れることができないので安全性が高い構成となっている。 In addition, since the spray device 131 is mounted in the outer case 127, it cannot be easily touched by a human hand, and thus has a high safety configuration.
 また、本実施の形態では、噴霧装置131が設けられた野菜室108の室内冷気を冷却室110に戻す吸込み口126を覆い、かつ水分供給口138を有する吸込み口カバー126aが設けられており、噴霧装置131を収納する外郭ケース127と吸込み口カバー126aとが連結されているので、野菜室108内を設定温度に維持するため定期的に冷却室110へ冷気を送り込むための吸込み口カバー126aと、噴霧装置131を収納し水分供給口138から野菜室108内の高湿冷気を取り込みミストを噴霧させ、その他貯蔵室へもミストを拡散させるための外郭ケース127とを有することとなり、それぞれの機能を追求すべく外郭ケース127、吸込み口カバー126aの本体や開口部等の形状やサイズの最適化を図ることができる。 Further, in the present embodiment, a suction port cover 126a that covers the suction port 126 that returns the indoor cold air of the vegetable chamber 108 provided with the spraying device 131 to the cooling chamber 110 and has a moisture supply port 138 is provided. Since the outer case 127 that houses the spraying device 131 and the suction port cover 126a are connected to each other, the suction port cover 126a for periodically feeding cool air to the cooling chamber 110 in order to maintain the inside of the vegetable compartment 108 at the set temperature, And an outer case 127 for storing the spray device 131, taking in the high-humidity cold air in the vegetable compartment 108 from the moisture supply port 138, spraying the mist, and diffusing the mist also into the other storage compartment. To optimize the shape and size of the outer case 127 and the main body and opening of the suction port cover 126a Kill.
 また、本実施の形態では、冷却室110と、貯蔵室とが繋がる風路141において開閉可能なダンパ装置141bを有しており、ダンパ装置141bが開いているとき、噴霧装置によりミストが噴霧される時があるので、生成したミストは、ダンパ装置141bが開いているときに風路141を通じて噴霧装置131が設けられた野菜室108以外の冷蔵室104にもミストを供給することができる。 Moreover, in this Embodiment, it has the damper apparatus 141b which can be opened and closed in the air path 141 which connects the cooling chamber 110 and a storage room, and when the damper apparatus 141b is open, mist is sprayed by the spray apparatus. Therefore, the generated mist can be supplied to the refrigerator compartment 104 other than the vegetable compartment 108 provided with the spraying device 131 through the air passage 141 when the damper device 141b is open.
 なお、噴霧装置131が設けられた野菜室108へのミストの供給は、外郭ケース127に設けられた水分供給口138や吸込み口カバー126aに設けられた開口部147を通じて、主にダンパ装置141bが閉じているときに行われる。 The supply of mist to the vegetable compartment 108 provided with the spray device 131 is mainly performed by the damper device 141b through the moisture supply port 138 provided in the outer case 127 and the opening 147 provided in the suction port cover 126a. Performed when closed.

FIG. 7 is a longitudinal sectional view of the refrigerator according to the second embodiment of the present invention, FIG. 8 is a schematic diagram showing the positional relationship between the air passage and each storage room in the refrigerator according to the second embodiment of the present invention, and FIG. It is sectional drawing which shows arrangement | positioning of the suction cover and outer case in the refrigerator of Embodiment 2.
 なお、実施の形態1と同様の構成および同様の技術思想が適用できる部分については、説明を省略するが、実施の形態1の構成に本実施の形態を組み合わせて実施することで不具合がない限り組み合わせて適用することが可能である。 In addition, although description is abbreviate | omitted about the part which can apply the structure similar to Embodiment 1, and the same technical idea, unless there is a malfunction by combining this Embodiment with the structure of Embodiment 1, and implementing it. It is possible to apply in combination.
 図7~図9に示すように、本実施の形態では野菜室108からの冷気を冷却室110へ戻すための吸込み口126にダンパ装置141bが設けられている。ここでダンパ装置は開閉可能であり、開いている時は野菜室の冷気を冷却室へと送りことはもちろんのこと、噴霧装置131で発生したミストを冷却室へ送り込み、風路を通じて冷蔵室104等の全貯蔵室へミストが拡散していく。 As shown in FIGS. 7 to 9, in the present embodiment, a damper device 141b is provided in the suction port 126 for returning the cold air from the vegetable compartment 108 to the cooling compartment 110. Here, the damper device can be opened and closed. When the damper device is open, not only the cool air in the vegetable compartment is sent to the cooling chamber, but also the mist generated in the spraying device 131 is sent to the cooling chamber, and the refrigerator compartment 104 is passed through the air passage. Mist spreads to all storage rooms.
 一方、ダンパ装置141bが閉じている時は野菜室108の冷気と噴霧装置131で発生したミストは吸込み口126を通過することができず、冷気とミストともに野菜室108内に拡散していくこととなる。 On the other hand, when the damper device 141b is closed, the cold air in the vegetable compartment 108 and the mist generated by the spraying device 131 cannot pass through the suction port 126, and both the cold air and the mist diffuse into the vegetable compartment 108. It becomes.
 以上のように、本実施の形態2においては、噴霧装置131が設けられた野菜室108の室内冷気を冷却室110に戻す吸込み口126にダンパ装置141bが設けられているので、発生したミストの各貯蔵室への配分がより精度よく制御できる。特に、噴霧装置131を設けた野菜室108のミスト噴霧量の調整が容易であり、ミスト噴霧量の多少に応じて、ダンパ装置141bの開閉という簡易な動作で実施できる。 As described above, in the second embodiment, since the damper device 141b is provided at the suction port 126 for returning the indoor cold air of the vegetable compartment 108 provided with the spray device 131 to the cooling chamber 110, the generated mist Distribution to each storage room can be controlled more accurately. In particular, the mist spray amount in the vegetable compartment 108 provided with the spray device 131 can be easily adjusted, and can be implemented by a simple operation of opening and closing the damper device 141b according to the amount of the mist spray amount.
 また、現在、冷凍サイクルの冷媒としては、地球環境保全の観点から地球温暖化係数が小さい可燃性冷媒であるイソブタンが使用されているものが主流になっている。 In addition, at present, as the refrigerant for the refrigeration cycle, the one that uses isobutane, which is a flammable refrigerant with a low global warming potential, has become the mainstream from the viewpoint of global environmental conservation.
 この炭化水素であるイソブタンは冷気と比較して常温、大気圧下で約2倍の比重であり、圧縮機109の停止時に冷凍システムから可燃性冷媒であるイソブタンが漏洩した場合には冷気よりも重いので下方に滞留することになる。したがって、仮に冷却器112からイソブタンが野菜室108に漏洩したとしても、噴霧装置131が野菜室108の上面に設置されているため、噴霧装置131付近が可燃濃度になる可能性を極めて低くすることができるので、噴霧装置131に高電圧を印加する場合でも、安全性を確保することができる。 This isobutane, which is a hydrocarbon, has a specific gravity approximately twice that of cold air at room temperature and atmospheric pressure. If isobutane, which is a flammable refrigerant, leaks from the refrigeration system when the compressor 109 is stopped, it is more than cold air. Because it is heavy, it will stay downward. Therefore, even if isobutane leaks from the cooler 112 to the vegetable compartment 108, since the spraying device 131 is installed on the top surface of the vegetable compartment 108, the possibility that the vicinity of the spraying device 131 becomes a flammable concentration is extremely reduced. Therefore, safety can be secured even when a high voltage is applied to the spray device 131.
 (実施の形態3)
 なお、上述の実施の形態と同様の構成および同様の技術思想が適用できる部分については、説明を省略するが、上述の実施の形態の構成に本実施の形態を組み合わせて実施することで不具合がない限り組み合わせて適用することが可能である。
(Embodiment 3)
In addition, although description is abbreviate | omitted about the part which can apply the same structure and the same technical idea as the above-mentioned embodiment, there is a malfunction by combining this embodiment with the structure of the above-mentioned embodiment. As long as there is not, it is possible to apply in combination.
 風路141にはダンパ装置241が設けられ風路内の風量調整を行なうもので、本実施の形態では冷蔵室104への風量調整により室内の温度を所定の温度範囲となるようにしている。 A damper device 241 is provided in the air passage 141 to adjust the air volume in the air passage. In this embodiment, the air temperature to the refrigerator compartment 104 is adjusted so that the room temperature falls within a predetermined temperature range.
 本実施の形態では、専用区画は、噴霧装置を覆う外郭ケース127で形成しており、外郭ケース127内空間は噴霧装置131が備えられた貯蔵室である野菜室108から風路141へ冷気を戻す吸込み口と連通している。 In the present embodiment, the dedicated section is formed by an outer case 127 that covers the spraying device, and the inner space of the outer case 127 cools air from the vegetable compartment 108, which is a storage room provided with the spraying device 131, to the air passage 141. It communicates with the return inlet.
 噴霧装置131は、空気中の水分を結露させることで生成する結露水を用いてミストが噴霧されるものであって、主に霧化部139、電圧印加部133、伝熱冷却部材である冷却ピン134で構成され、外郭ケース127には湿度供給口138が設けられている。 The spraying device 131 sprays mist using condensed water generated by condensing moisture in the air, and is mainly an atomizing unit 139, a voltage applying unit 133, and a cooling that is a heat transfer cooling member. A humidity supply port 138 is provided in the outer case 127.
 冷却ピン134の形状は、直方体や正多角形体でもよく、これらの多角形の場合は、円柱と比較して位置決めがしやすく、正確な位置に噴霧装置131を備えることができる。 The shape of the cooling pin 134 may be a rectangular parallelepiped or a regular polygon. In the case of these polygons, positioning is easier than a cylinder, and the spray device 131 can be provided at an accurate position.
 冷却ピン134は断熱材152の内部を介してその先端を冷凍室107側に凸状に延出させている突出部134aを有している。この突出部134aの先端面および周囲には断熱材を備えず、冷凍室内壁となるABSなどの樹脂で成型された内壁も同様に凸状に冷蔵室107側に延出している。この延出部は、冷凍室107を引き出し式の貯蔵室としているので、内部の収納容器によって扉を開けた場合でも使用者の目に入らない配置としている。 The cooling pin 134 has a protruding portion 134 a that protrudes from the inside of the heat insulating material 152 in a convex shape toward the freezing chamber 107. The protruding surface 134a has no heat insulating material on the front end surface and the periphery thereof, and the inner wall formed of a resin such as ABS serving as the freezer compartment wall also extends in a convex manner toward the refrigerator compartment 107 side. Since the freezing chamber 107 is a drawer-type storage chamber, the extending portion is arranged so that it is not visible to the user even when the door is opened by an internal storage container.
 冷凍室107の温度は-22℃~-15℃であり、冷却ピン134の先端を延出することで、より効果的に冷却ピン134の全体を冷却することができる。あるいは、冷却ピン134の先端表面を冷凍室107に露出させるという構成でも良い。さらには、冷却ピン134を断熱材152の中に埋め込んだ状態でも良いが、この場合は冷却ピン134の冷却効果が本実施の形態の場合よりも小さくなる。 The temperature of the freezing chamber 107 is −22 ° C. to −15 ° C. By extending the tip of the cooling pin 134, the entire cooling pin 134 can be cooled more effectively. Or the structure of exposing the front-end | tip surface of the cooling pin 134 to the freezer compartment 107 may be sufficient. Furthermore, the cooling pin 134 may be embedded in the heat insulating material 152, but in this case, the cooling effect of the cooling pin 134 is smaller than that in the present embodiment.
 また、霧化部139に対向している位置で貯蔵室(野菜室108)側にドーナツ型の内部が中空となった円盤状の対向電極136が、霧化部139の先端と一定距離を保つように取付けられている。 In addition, a disk-shaped counter electrode 136 having a hollow donut-shaped interior on the storage chamber (vegetable chamber 108) side at a position facing the atomizing portion 139 maintains a certain distance from the tip of the atomizing portion 139.

 この風路141において、冷却器112から各貯蔵室へ冷気が流れる風路141を吐出風路141aとし、各貯蔵室を冷却した後の冷気が書く貯蔵室から冷却器112へ冷気が流れる風路141を吸込み風路141bとし、風路141の簡単な構造を図13に示した。 In this air passage 141, the air passage 141 through which cool air flows from the cooler 112 to each storage chamber is referred to as a discharge air passage 141a, and the air passage through which cold air flows from the storage chamber to which the cool air is written after cooling each storage chamber to the cooler 112. 141 is a suction air passage 141b, and a simple structure of the air passage 141 is shown in FIG.
 まず冷却室110で熱交換された冷気は、冷凍室107、切替室105、製氷室106へ供給されるとともに、冷却器112から冷蔵室104へ流れる吐出風路141a内に備えられたダンパ装置241が開いている時には、冷蔵室104へ冷気が供給される。また、ダンパ装置241を通過した冷気は冷蔵室104内へ向かう風路141と枝分かれした野菜室108へ通じる吐出風路141aを通じて、野菜室108へと供給される。 First, the cold air heat-exchanged in the cooling chamber 110 is supplied to the freezing chamber 107, the switching chamber 105, and the ice making chamber 106, and the damper device 241 provided in the discharge air passage 141 a that flows from the cooler 112 to the refrigerating chamber 104. When is open, cold air is supplied to the refrigerator compartment 104. In addition, the cold air that has passed through the damper device 241 is supplied to the vegetable compartment 108 through the air passage 141 that goes into the refrigerator compartment 104 and the discharge air passage 141 a that leads to the branched vegetable compartment 108.
 なお、各貯蔵室を冷却した後の冷気は再び、吸込み風路141bを通じて冷却室110へと戻ることとなり、このサイクルを繰り返すことで冷蔵庫を所定の温度に冷却する。 The cool air after cooling each storage room returns to the cooling room 110 again through the suction air passage 141b, and the refrigerator is cooled to a predetermined temperature by repeating this cycle.
 ここで野菜室108を循環した冷気は、吸込み風路141bへの入り口である吸込み口126を通じて冷却室110へと戻るが、図14、図15に示す通り、噴霧装置131は専用区画である外郭ケース127に収納されており、外郭ケース127には野菜室108の高湿冷気を取り込むための開口部である水分供給口138が設けられている。 Here, the cold air circulated through the vegetable chamber 108 returns to the cooling chamber 110 through the suction port 126 which is the entrance to the suction air passage 141b. However, as shown in FIGS. 14 and 15, the spraying device 131 is an outer section which is a dedicated section. The outer case 127 is provided with a moisture supply port 138 that is an opening for taking in high-humidity cold air from the vegetable compartment 108.
 取り込まれた高湿冷気は冷凍温度帯からの熱伝導によって露点以下となった霧化部139で冷却されて、結露してミストが噴霧される。この時、噴霧されたミストは専用区画内に充満したうえで、分流手段によって、野菜室108へ供給されるか、他の貯蔵室へ供給されるかが変化する。 The high-humidity cold air that has been taken in is cooled by the atomization section 139 that has become below the dew point due to heat conduction from the freezing temperature zone, and is condensed and sprayed with mist. At this time, after the sprayed mist is filled in the exclusive section, whether it is supplied to the vegetable room 108 or another storage room is changed by the diversion means.
 本実施の形態では、分流手段にファン203を備え、ファン203の作動の有無によってミストを供給する貯蔵室を切り換える構成としている。 In the present embodiment, the flow dividing means is provided with a fan 203, and the storage chamber for supplying mist is switched depending on whether the fan 203 is activated or not.
 具体的には、ファン203が停止している場合には、専用区画内に充満しているミストは開口部147を介して、野菜室108内へと供給され、ファン203が作動しているときは、外郭ケース127は吸込み口126と連結しているので、吸込み口126、風路141を通じて冷却室110へミストが運ばれて、冷却室を介して吐出風路141aに流れる冷気の流れに乗って冷蔵庫100の各貯蔵室に供給される。 Specifically, when the fan 203 is stopped, the mist filled in the dedicated section is supplied into the vegetable compartment 108 through the opening 147, and the fan 203 is operating. Since the outer case 127 is connected to the suction port 126, the mist is transported to the cooling chamber 110 through the suction port 126 and the air passage 141, and rides on the flow of cold air flowing to the discharge air passage 141a through the cooling chamber. And supplied to each storage room of the refrigerator 100.
 また、吸込み口カバー126aは吸込み口126と連結しており、野菜室108の冷気を開口部147から取り入れて、吸込み口126、吸込み風路141bを通じて冷却室110へ運ぶようになっている。 Further, the suction port cover 126a is connected to the suction port 126 so that the cool air of the vegetable chamber 108 is taken in from the opening 147 and is conveyed to the cooling chamber 110 through the suction port 126 and the suction air passage 141b.
 ここで、本実施の形態では外郭ケース127と吸込み口カバー126aとは連通し、さらに連結している。なお、外郭ケース127が吸込み口カバー126aを兼用されることもあり、その場合、水分供給口138が開口部147の役割も兼用することができる。 Here, in the present embodiment, the outer case 127 and the suction port cover 126a are in communication with each other. The outer case 127 may also serve as the suction port cover 126a. In this case, the moisture supply port 138 can also serve as the opening 147.
 冷却ピン134を冷却する冷却手段である冷凍室107内の冷凍温度帯の冷気は、冷却システムの運転により冷却器112で生成し、ファン203により-15~-25℃程度の冷気が流れ、伝熱冷却部材である冷却ピン134が例えば0~-10℃程度に冷却される。 Cold air in the freezing temperature zone in the freezer compartment 107, which is a cooling means for cooling the cooling pins 134, is generated by the cooler 112 by the operation of the cooling system, and cool air of about −15 to −25 ° C. flows through the fan 203 and is transmitted. The cooling pin 134 as a heat cooling member is cooled to about 0 to −10 ° C., for example.
 このとき、冷却ピン134は、良熱伝導部材であるため、冷熱を非常に伝えやすく、冷却ピン134を介して霧化部139も0~-10℃程度に間接的に冷却される。 At this time, since the cooling pin 134 is a good heat conduction member, it is very easy to transmit cold heat, and the atomizing portion 139 is also indirectly cooled to about 0 to −10 ° C. via the cooling pin 134.
 ここで、野菜室108の温度は2℃から7℃で、冷却ピン134の野菜室208側は、周辺の空気と10℃以上の温度差が生じ、かつ野菜などからの蒸散により比較的高湿状態であるので霧化部139は露点温度以下となり、霧化部139に水が生成し、水滴が付着する。 Here, the temperature of the vegetable compartment 108 is 2 ° C. to 7 ° C., and the temperature of the cooling pin 134 on the side of the vegetable compartment 208 is 10 ° C. or more with the surrounding air, and the humidity is relatively high due to transpiration from the vegetables. Since it is in the state, the atomization part 139 becomes below the dew point temperature, water is generated in the atomization part 139, and water droplets adhere.
 水滴が付着した霧化部139に電圧印加部133により高電圧(例えば4~10kV)を印加させてコロナ放電が起こし、霧化部139の先端の水滴が、静電エネルギーにより微細化され、霧化される。さらに液滴が帯電しているためレイリー分裂により数nmレベルの電荷をもったナノレベルの微細ミストと同時に、オゾンやOHラジカルなどが発生する。 A high voltage (for example, 4 to 10 kV) is applied to the atomizing unit 139 to which water droplets have adhered by the voltage applying unit 133 to cause corona discharge, and the water droplets at the tip of the atomizing unit 139 are refined by electrostatic energy, It becomes. Furthermore, since the droplets are charged, ozone, OH radicals, and the like are generated simultaneously with nano-level fine mist having a charge of several nanometers due to Rayleigh splitting.
 噴霧装置131からミストを噴霧するタイミングは図16によって説明する。まず、冷蔵庫100においてファン203は冷却室110で生成する冷気を全貯蔵室へ供給するために定期的にON/OFFをしており、ON時にファン203が動作し、OFF時にファン203は停止している状態となる。 The timing of spraying mist from the spray device 131 will be described with reference to FIG. First, in the refrigerator 100, the fan 203 is periodically turned on / off in order to supply the cool air generated in the cooling chamber 110 to all the storage rooms. The fan 203 operates when it is on, and the fan 203 stops when it is off. It will be in the state.
 また、分流手段としてのダンパ装置241は冷蔵室104、野菜室108へ冷却室110で生成する冷気を分配するために定期的に開閉しており、この開閉に伴って冷蔵室104、野菜室108へのミスト供給を切り換えることが可能となる。 Further, the damper device 241 as a diversion unit is periodically opened and closed to distribute the cold air generated in the cooling chamber 110 to the refrigerator compartment 104 and the vegetable compartment 108, and accompanying this opening and closing, the refrigerator compartment 104 and the vegetable compartment 108. It becomes possible to switch the mist supply to.
 ここで本実施の形態3では、分流手段としてのファン203が動作する時に高電圧が印加される場合(噴霧2)があり、この時に発生したミストが吸込み口126を通じて冷却室110へと取り込まれるとともに、冷却室110と連通している冷凍室107、切替室105、製氷室106へとミストが供給される。またこの時、ダンパ装置241が開いている場合には、冷蔵室104へ吐出風路141aを通じてミストが供給される。 Here, in the third embodiment, there is a case where a high voltage is applied (spray 2) when the fan 203 as the flow dividing unit operates, and the mist generated at this time is taken into the cooling chamber 110 through the suction port 126. At the same time, mist is supplied to the freezing chamber 107, the switching chamber 105, and the ice making chamber 106 that communicate with the cooling chamber 110. At this time, if the damper device 241 is open, the mist is supplied to the refrigerator compartment 104 through the discharge air passage 141a.
 また、分流手段であるファン203が動作しない時にも高電圧が印加される時(噴霧1)があり、このときミストは野菜室108内に噴霧される。このようにファン203が停止している場合は、ミストは吸込み口126を通過することはなく、外郭ケース127内に充満した後、拡散し、水分供給口138や吸込み口カバー126aの開口部147を通じて野菜室108内に供給される。 Also, there is a time when a high voltage is applied (spray 1) even when the fan 203 as a flow dividing means does not operate. At this time, the mist is sprayed into the vegetable compartment 108. Thus, when the fan 203 is stopped, the mist does not pass through the suction port 126, fills the outer case 127, diffuses, and opens the moisture supply port 138 and the opening 147 of the suction port cover 126 a. It is supplied into the vegetable compartment 108 through.
 以上のように、本実施の形態3においては、噴霧装置131は野菜室108内の専用区画に設けられた外郭ケース127内に収納されており、外郭ケース127は野菜室108から冷却室110へ室内冷気を戻す吸込み口126と連結されており、外郭ケース127における野菜室108に対する面に開口部である水分供給口138が設けられている。この時、分流手段であるファン203の作動の有無によってミストを供給する貯蔵室を切り換えるものであり、ファン203が作動していない場合には、噴霧装置が備えられた貯蔵室である野菜室108にミストが噴霧され、ファン203が作動している場合には、噴霧装置が備えられた貯蔵室以外の他の貯蔵室へミストが噴霧される。 As described above, in the third embodiment, the spray device 131 is housed in the outer case 127 provided in the dedicated compartment in the vegetable compartment 108, and the outer case 127 is transferred from the vegetable compartment 108 to the cooling chamber 110. A water supply port 138 that is an opening is provided on the surface of the outer case 127 that faces the vegetable compartment 108, and is connected to a suction port 126 that returns the indoor cool air. At this time, the storage chamber for supplying mist is switched depending on whether or not the fan 203 which is a flow dividing unit is operated. When the fan 203 is not operating, the vegetable chamber 108 which is a storage chamber provided with a spraying device. In the case where the mist is sprayed and the fan 203 is operating, the mist is sprayed to a storage chamber other than the storage chamber provided with the spraying device.
 さらに、外郭ケース127は野菜室108の吸込み口126に連結されているため、ミストがその他の貯蔵室へ拡散できる経路が形成されるとともに、ミストはファン203が動作するときに噴霧されているので、ファン203による強制対流を利用して、他の貯蔵室へミストが自ずと供給される構成が冷蔵庫100において実現できる。 Further, since the outer case 127 is connected to the suction port 126 of the vegetable compartment 108, a path through which the mist can diffuse to other storage compartments is formed, and the mist is sprayed when the fan 203 operates. A configuration in which mist is naturally supplied to another storage room using forced convection by the fan 203 can be realized in the refrigerator 100.
 よって、冷凍サイクル内の部品であるファン203を利用して、冷気の流れに乗せた強制対流によってミストを分流させることができ、簡単な構成で確実に必要に応じた任意の貯蔵室へミスト供給を行うことが可能となる。 Therefore, using the fan 203, which is a component in the refrigeration cycle, the mist can be diverted by forced convection in the cold air flow, and the mist can be supplied to any storage room as required with a simple configuration. Can be performed.
 なお、噴霧装置131が設けられた野菜室108へのミストの供給は、専用区画を形成する外郭ケース127に設けられた水分供給口138を通じて、主にファン203が動作しないときに行われる。 In addition, supply of the mist to the vegetable compartment 108 provided with the spraying device 131 is performed mainly when the fan 203 does not operate through the moisture supply port 138 provided in the outer case 127 forming the dedicated section.
 また、コロナ放電で霧化をおこなう方式である静電霧化を用いた場合には、発生した微細ミストに、オゾンやOHラジカルなどが含まれ、これらの酸化力により、野菜室108内の脱臭や野菜表面を抗菌、殺菌することができると同時に、野菜表面に付着する農薬やワックスなどの有害物質を酸化分解・除去することができる。 In addition, when electrostatic atomization, which is a method of atomizing with corona discharge, is used, the generated fine mist contains ozone, OH radicals, etc., and these oxidizing powers deodorize the vegetable compartment 108. In addition to antibacterial and sterilizing the surface of vegetables and vegetables, harmful substances such as agricultural chemicals and wax adhering to the surface of vegetables can be oxidatively decomposed and removed.
 また、本実施の形態では、噴霧装置131が設けられた野菜室108の室内冷気を冷却室110に戻す吸込み口126を覆い、かつ水分供給口138を有する吸込み口カバー126aが設けられており、噴霧装置131を収納する外郭ケース127と吸込み口カバー126aとが連結されている。 Further, in the present embodiment, a suction port cover 126a that covers the suction port 126 that returns the indoor cold air of the vegetable chamber 108 provided with the spraying device 131 to the cooling chamber 110 and has a moisture supply port 138 is provided. The outer case 127 that houses the spray device 131 and the suction port cover 126a are connected.
 これによって、野菜室108内を設定温度に維持するため定期的に冷却室110へ冷気を送り込むための吸込み口カバー126aと、噴霧装置131を収納し水分供給口138から野菜室108内の高湿冷気を取り込み結露水を発生させるので、ミストが備えられている貯蔵室だけでなく、その他貯蔵室へも十分な量のミストを供給するための専用区画を有することとなり、それぞれの機能を追求すべく外郭ケース127、吸込み口カバー126aの本体や開口部等の形状やサイズの最適化を図ることができる。 Thereby, in order to maintain the inside of the vegetable compartment 108 at the set temperature, the suction port cover 126a for regularly sending cool air to the cooling chamber 110 and the spray device 131 are housed, and the high humidity in the vegetable compartment 108 is stored from the moisture supply port 138. Since cold air is taken in and condensed water is generated, not only the storage room equipped with mist, but also a dedicated section for supplying a sufficient amount of mist to other storage rooms will be pursued. Accordingly, it is possible to optimize the shape and size of the main body and the opening of the outer case 127 and the suction port cover 126a.
 また、本実施の形態では、冷却室110と、貯蔵室とが繋がる風路141において、冷却室110から貯蔵室への戻り風路には、開閉可能なダンパ装置241を有しており、ダンパ装置241が開いているとき、噴霧装置によりミストが噴霧される時があるので、生成したミストは、ダンパ装置241が開いているときに風路141を通じて噴霧装置131が設けられた野菜室108以外の冷蔵室104にもミストを供給することができる。 In the present embodiment, in the air passage 141 connecting the cooling chamber 110 and the storage chamber, the return air passage from the cooling chamber 110 to the storage chamber has the damper device 241 that can be opened and closed. Since the mist may be sprayed by the spray device when the device 241 is open, the generated mist is other than the vegetable compartment 108 provided with the spray device 131 through the air passage 141 when the damper device 241 is open. The mist can also be supplied to the refrigerator compartment 104 of the refrigerator.
 なお、噴霧装置131が設けられた野菜室108へのミストの供給は、外郭ケース127に設けられた水分供給口138や吸込み口カバー126aに設けられた開口部147を通じて、主にダンパ装置241が閉じているときに行われる。 The supply of mist to the vegetable compartment 108 provided with the spraying device 131 is mainly performed by the damper device 241 through the moisture supply port 138 provided in the outer case 127 and the opening 147 provided in the suction port cover 126a. Performed when closed.
 なお、本実施の形態において、噴霧装置131(の霧化部139)でミストが噴霧される貯蔵室を野菜室108としたが、冷蔵室104や切替室105などの他の温度帯の貯蔵室でもよく、冷蔵庫の商品構成によって専用区画をどの貯蔵室に設置するかを適宜選択することが可能となる。 In the present embodiment, the storage room in which the mist is sprayed by the spraying device 131 (the atomizing section 139) is the vegetable room 108, but the storage room in other temperature zones such as the refrigerator room 104 and the switching room 105. However, according to the product configuration of the refrigerator, it is possible to appropriately select in which storage room the dedicated section is installed.

13 is a cross-sectional view showing the arrangement of the suction cover and the outer case in the refrigerator according to the fourth embodiment of the present invention, FIG. 14 is a top view of the vegetable compartment in the refrigerator according to the fourth embodiment of the present invention, and FIG. It is a three-dimensional view showing the structure of the outer cover in the refrigerator according to the fourth embodiment.
 なお、上述の実施の形態と同様の構成および同様の技術思想が適用できる部分については、説明を省略するが、上述の実施の形態の構成に本実施の形態を組み合わせて実施することで不具合がない限り組み合わせて適用することが可能である。 In addition, although description is abbreviate | omitted about the part which can apply the same structure and the same technical idea as the above-mentioned embodiment, there is a malfunction by combining this embodiment with the structure of the above-mentioned embodiment. As long as there is not, it is possible to apply in combination.
 本実施の形態では、図13~図15に示すように外郭ケース127に噴霧装置131に対して上流側に開口部としての水分供給口142、下流側にそれぞれ開口部としてのミスト排出口143が設けられている。ここで上流、下流とは冷気の流れに応じて述べており、吸い込み口カバー126aから遠い場所に位置するものを上流側とし、他方側すなわち貯蔵室側に位置するものを下流側としている。 In the present embodiment, as shown in FIGS. 13 to 15, the outer casing 127 has a moisture supply port 142 as an opening on the upstream side with respect to the spraying device 131 and a mist discharge port 143 as an opening on the downstream side. Is provided. Here, “upstream” and “downstream” are described according to the flow of cold air, and those located far from the suction port cover 126a are the upstream side, and those located on the other side, that is, the storage chamber side, are the downstream side.
 また、外郭ケース127は図14に示すように接続部147にて吸い込み口カバー126aと連結しており、ファン203が動作時に噴霧装置131で発生したミストは吸い込み口126に吸い込まれ、その後冷蔵庫100の全室へと拡散していく。 Further, as shown in FIG. 14, the outer case 127 is connected to the suction port cover 126 a at the connection portion 147, and mist generated in the spray device 131 when the fan 203 is operated is sucked into the suction port 126, and then the refrigerator 100. Will spread to all rooms.
 本実施の形態における外郭ケース127の内部の構造は図15に示す通りであり、噴霧装置131と制御基板144を収納しており、水分供給口142、ミスト排出口143や冷蔵庫100への取り付けや外郭ケース127の強度確保のための各種リブが構成されている。 The internal structure of the outer case 127 in the present embodiment is as shown in FIG. 15, which houses the spray device 131 and the control board 144, and is attached to the moisture supply port 142, the mist discharge port 143 and the refrigerator 100. Various ribs for securing the strength of the outer case 127 are configured.
 噴霧装置131の冷却ピン134の上面にはブチルテープ145とアルミテープ146を貼付しており、アルミテープ146は冷凍室107の底面に接している。 The butyl tape 145 and the aluminum tape 146 are stuck on the upper surface of the cooling pin 134 of the spraying device 131, and the aluminum tape 146 is in contact with the bottom surface of the freezer compartment 107.
 ここで、ブチルテープ145は冷却ピン134を隙間なく取り付けるため寸法公差を吸収する目的で貼付している。また、アルミテープ146は冷却ピン134のおよそ中間部まで貼付することでブチルテープ145において形成される温度勾配の影響を低減し、冷凍室107の冷気を有効に活用して霧下部139を効果的に冷却させている。 Here, the butyl tape 145 is affixed for the purpose of absorbing dimensional tolerances in order to attach the cooling pins 134 without gaps. In addition, the aluminum tape 146 is applied to the middle portion of the cooling pin 134 to reduce the influence of the temperature gradient formed in the butyl tape 145, and the cold air in the freezer compartment 107 is effectively used to effectively use the lower mist 139. Let it cool down.
 水分供給口142とミスト排出口143はそれぞれ複数の穴で構成しており、本実施の形態では穴の寸法はともに縦12mm、横4mmの長方形としている。この程度の寸法であれば冷蔵庫100の運転中にも使用者が誤って指などを外郭ケース127の内部で入れることがないので、噴霧装置131で印加される電圧によって使用者が感電する心配がない。 The water supply port 142 and the mist discharge port 143 are each composed of a plurality of holes, and in this embodiment, the dimensions of the holes are both rectangles of 12 mm length and 4 mm width. With such a size, the user does not accidentally put a finger or the like inside the outer case 127 even during operation of the refrigerator 100, so there is a concern that the user may be electrocuted by the voltage applied by the spray device 131. Absent.
 制御基板144は高圧印加部133を有しており、霧化部139と対向電極136との間に高電圧を定期的にON/OFFさせる役割を持っている。 The control board 144 has a high voltage application unit 133 and has a role of periodically turning on / off the high voltage between the atomization unit 139 and the counter electrode 136.
 以上のように、本実施の形態4においては、外郭ケース127に貯蔵室108と連通する水分供給口142、ミスト排出口143が設けられており、水分供給口142は噴霧装置131に対して上流側に設けられ、ミスト排出口143は噴霧装置131に対して下流側に設けられているので、主にファン203が停止しているときに、外郭ケース127内で四方へ拡散するミストを水分供給口142、ミスト排出口143からもれなく貯蔵室108へ供給することができる。 As described above, in the fourth embodiment, the outer case 127 is provided with the moisture supply port 142 and the mist discharge port 143 communicating with the storage chamber 108, and the moisture supply port 142 is upstream of the spray device 131. Since the mist discharge port 143 is provided on the downstream side with respect to the spraying device 131, the mist that diffuses in all directions in the outer case 127 is mainly supplied when the fan 203 is stopped. It can be supplied to the storage chamber 108 from the mouth 142 and the mist discharge port 143.
 また、ミスト排出口143の面積の大きさによって、噴霧装置131が設けられた貯蔵室108へのミスト供給量を調整することができ、他貯蔵室への過剰なミスト拡散を抑制することができ、冷蔵庫全室に対して均衡が取れたミスト拡散が実現される。 Further, the amount of mist supplied to the storage chamber 108 provided with the spray device 131 can be adjusted by the size of the area of the mist discharge port 143, and excessive mist diffusion to other storage chambers can be suppressed. , Mist diffusion balanced in all the refrigerator rooms is realized.
 さらに、ファン203作動時には水分供給口142、ミスト排出口143から貯蔵室108内の高湿な冷気を取り込むが、風の流れは水分供給口143からミスト排出口の方向に流れており、噴霧装置131へ供給される高湿冷気は水分供給口142から取り込まれたものだけとなるが、水分供給口142から取り込む高湿冷気の風速が大きくなると、噴霧装置131において結露を発生することができないことがある。 Further, when the fan 203 is operated, high-humidity cold air in the storage chamber 108 is taken in from the moisture supply port 142 and the mist discharge port 143, but the flow of wind flows from the moisture supply port 143 to the mist discharge port. The high-humidity cold air supplied to 131 is only that taken in from the water supply port 142, but if the high-humidity cold air taken in from the water supply port 142 increases in wind speed, condensation cannot be generated in the spray device 131. There is.
 ここで本実施の形態ではミスト排出口143が設置されているので、水分供給口142から取り込む高湿冷気の風速を低減して噴霧装置131において結露を発生できるように調整することができ、ミスト噴霧の安定性を高めることができる。 Here, in the present embodiment, since the mist discharge port 143 is installed, it is possible to adjust the spray device 131 so as to generate dew condensation by reducing the wind speed of the high-humidity cold air taken in from the moisture supply port 142. Spray stability can be increased.

FIG. By implementing in combination, it is possible to apply in combination as long as there is no problem.
 本実施の形態では、図16~図18に示すように外郭ケース127の接続部147にミスト拡散調整材148が接続部147の断面積を絞るように設けられており、噴霧装置131で発生したミストがファン203動作時に吸い込み口126の方向へ拡散するときに障壁となり、ミスト拡散量の調整がされることになる。 In the present embodiment, as shown in FIGS. 16 to 18, a mist diffusion adjusting material 148 is provided at the connection portion 147 of the outer case 127 so as to reduce the cross-sectional area of the connection portion 147, and is generated in the spray device 131. When the mist diffuses in the direction of the suction port 126 when the fan 203 is operating, it becomes a barrier, and the amount of mist diffusion is adjusted.
 なお、本実施の形態ではミスト排出口143を設けているが、ミスト拡散調整材148により冷蔵室104や野菜室108などの各貯蔵室へのミスト分配量を調整することが可能であるのでミスト排出口143を省略することもできる。 In this embodiment, the mist discharge port 143 is provided. However, since the mist distribution adjusting material 148 can adjust the mist distribution amount to each storage room such as the refrigerator compartment 104 and the vegetable compartment 108, the mist The discharge port 143 can also be omitted.
 また、ミスト拡散調整材148の作用は噴霧装置131で発生したミストの吸い込み口126方向への拡散を抑制するものであり、接続部147の断面積を絞ることができるのであれば形状は問われない。図18ではミスト拡散調整材148は四角形の板状としているが、図19に示すようにL字型のミスト拡散調整材148aや開口部149を有するミスト拡散調整材148bであってもよい。 Further, the action of the mist diffusion adjusting material 148 suppresses the diffusion of the mist generated in the spray device 131 in the direction of the suction port 126, and the shape is not limited as long as the cross-sectional area of the connecting portion 147 can be reduced. Absent. In FIG. 18, the mist diffusion adjusting material 148 has a rectangular plate shape, but may be an L-shaped mist diffusion adjusting material 148a or a mist diffusion adjusting material 148b having an opening 149 as shown in FIG.
 以上のように、本実施の形態5においては、外郭ケース127において噴霧装置131に対する上流側に水分供給口142が設けられ、噴霧装置131に対する下流側にミスト拡散調整材148が設けられているので、噴霧装置131で発生したミストはミスト拡散調整材148が障壁となり、吸い込み口126方向への拡散が抑制され、冷凍室107や冷蔵室104などへの過剰なミスト拡散を抑制することができ、冷蔵庫全室に対して均衡が取れたミスト拡散が実現される。 As described above, in the fifth embodiment, in the outer case 127, the moisture supply port 142 is provided on the upstream side with respect to the spraying device 131, and the mist diffusion adjusting material 148 is provided on the downstream side with respect to the spraying device 131. In the mist generated in the spray device 131, the mist diffusion adjusting material 148 becomes a barrier, diffusion in the suction port 126 direction is suppressed, and excessive mist diffusion to the freezer compartment 107, the refrigerator compartment 104, and the like can be suppressed. A balanced mist diffusion is realized for all the refrigerator rooms.

FIG. 20 is a longitudinal sectional view of a part of the refrigerator in the sixth embodiment of the present invention.
 本実施の形態は、貯蔵室の配置構成を冷蔵室の第二貯蔵室に野菜室を設置したものである。 In the present embodiment, the vegetable compartment is installed in the second storage room of the refrigerator room in the arrangement configuration of the storage room.
 なお、実施の形態3から実施の形態5と同様の構成および同様の技術思想が適用できる部分については、説明を省略するが、実施の形態3から実施の形態4の構成に本実施の形態を組み合わせて実施することで不具合がない限り組み合わせて適用することが可能である。 In addition, although description is abbreviate | omitted about the part which can apply the structure similar to Embodiment 3 to Embodiment 5, and the same technical idea, this Embodiment is added to the structure of Embodiment 3 to Embodiment 4. FIG. By implementing in combination, it is possible to apply in combination as long as there is no problem.
 図のように専用区画510を形成する外殻ケース127は、噴霧装置131が備えられた貯蔵室として野菜室108側が常に専用区画510と連通しており、隣接する第二貯蔵室として、野菜室とおよそ10℃未満の庫内温度差の貯蔵室である冷蔵室との間の仕切り壁内に設けられている。このように第二貯蔵室との温度差が10℃未満である場合には、仕切り壁内に断熱材を注入することなく、このような仕切り壁のみの空気断熱で断熱性を保持することが可能であるので、仕切り壁内の空間を用いて専用区画を形成することができる。 As shown in the figure, the outer shell case 127 forming the dedicated compartment 510 has a vegetable compartment 108 side that is always in communication with the dedicated compartment 510 as a storage room provided with the spray device 131, and a vegetable room as an adjacent second storage room. And a refrigerating room, which is a storage room having a temperature difference of less than about 10 ° C., is provided in a partition wall. Thus, when the temperature difference with the second storage chamber is less than 10 ° C., heat insulation can be maintained by air insulation of such a partition wall without injecting a heat insulating material into the partition wall. Since it is possible, a dedicated section can be formed using the space in the partition wall.
 このように隣接区画との温度差が小さい場合には、冷凍温度帯で冷却することで結露を行うことで水供給を行うタイプは配置上難しいため、冷蔵室側から取り外し可能な水タンク501を噴霧装置131に備えている。 In this way, when the temperature difference between the adjacent compartments is small, the type of supplying water by performing dew condensation by cooling in the freezing temperature zone is difficult in terms of arrangement, so a water tank 501 that can be removed from the refrigerator compartment side is provided. The spray device 131 is provided.
 このような水タンクを備えた噴霧装置131は専用区画を形成する外郭ケース127内に備えられている。
また、外郭ケース内は風路141と連通しており、専用区画に貯留されたミストが風路141を介して噴霧装置131が備えられた貯蔵室である野菜室108以外の貯蔵室へ分流手段によって供給することができる。
The spraying device 131 having such a water tank is provided in an outer case 127 that forms a dedicated section.
Further, the inside of the outer case communicates with the air passage 141, and the mist stored in the dedicated section is diverted to a storage room other than the vegetable compartment 108 which is a storage room provided with the spray device 131 via the air passage 141. Can be supplied by.
 また、本実施の形態では貯蔵室間の仕切り壁内に噴霧装置131が備えられているので、どちら側の貯蔵室が噴霧装置131が備えられている貯蔵室であるのかが一義的には判断できないが、本実施の形態のように常に連通している開口部143が野菜室108側にあり、自然拡散によると野菜室108に多量のミストが噴霧されることから、本発明における噴霧装置131を備えた貯蔵室は野菜室108であると定義する。 Further, in the present embodiment, since the spray device 131 is provided in the partition wall between the storage chambers, it is uniquely determined which storage chamber is the storage chamber in which the spray device 131 is provided. However, the opening 143 that is always in communication as in the present embodiment is on the vegetable compartment 108 side, and a large amount of mist is sprayed on the vegetable compartment 108 by natural diffusion. Is defined as the vegetable compartment 108.
 この分流手段による分流方法は実施の形態3と同様に風路141内に備えられたファン203の作動の有無によってミストを供給する貯蔵室を切り換える構成や、ダンパ装置241の開閉によってミストを供給する貯蔵室を切り換える構成が適用できるものとする。 As in the third embodiment, the diversion method by the diversion means is configured to switch the storage chamber for supplying mist depending on whether the fan 203 provided in the air passage 141 is operated or to supply the mist by opening / closing the damper device 241. A configuration in which the storage room is switched can be applied.
 以上のように構成された冷蔵庫によると、貯蔵室間のデッドスペースを上手く利用して、専用区画を設けることができ、専用区画が貯蔵室の内容積に影響せず、より大容量の収納量を備えた冷蔵庫を実現できる。 According to the refrigerator configured as described above, the dedicated space can be provided by making good use of the dead space between the storage rooms, and the dedicated space does not affect the internal volume of the storage room, and the storage capacity is larger. A refrigerator equipped with can be realized.
 また、風路141とこの仕切り壁内の外郭ケース127を連通することで、簡単な構成で分流手段を用いて必要な貯蔵室にミストを供給することが可能と
