【０００１】[0001]
本考案は、食肉店、鮮魚店、スーパーマーケット、その他の食品売り場、食品 加工場、レストランその他の厨房等で、食肉、魚介類等の冷凍食品を解凍し、保 冷するのに使用する解凍保冷庫に関する。 The present invention is a defrosting refrigerator used for thawing and keeping frozen frozen foods such as meat and seafood in meat shops, fresh fish stores, supermarkets, other food shops, food processing plants, restaurants and other kitchens. Regarding
【０００２】[0002]
従来、冷凍食品を解凍するには、(1) 冷凍食品を常温で放置して解凍するか、 (2) 流水中で冷凍食品を解凍するか、(3) 保冷庫に冷凍食品を入れ、保冷庫内に 常温に近い冷気を循環させて冷凍食品を解凍するかのいずれかの方法にて行われ ている。しかしながら、前記常温で放置する解凍方法(1) では、常温で解凍する ため、食品の腐敗が進行し易く、前記流水を用いる解凍方法(2) では、流水中で 冷凍食品を扱うため、操作が複雑で厄介になり、また流水により食品の品質が劣 化するおそれがあり、前記常温に近い冷気を用いる方法(3) では、食品の鮮度低 下による食品本体からの体液浸出、すなわち、ドリップが生じ、また食品が比較 的低湿度の空気に曝されるため、食品の表面が乾燥し、さらに、上記方法(1) 〜 (3) のいずれの場合においても、ドリップ中や、食品に含まれる水中あるいは冷 気発生用の冷却水中に含まれている各種物質がバクテリア等にて腐敗し、異臭を 発するなど、不衛生になり易いという問題点を有している。このため、衛生状態 を良好に保ちながら冷凍食品を解凍できる解凍装置はほとんど知られていない。 Conventionally, to thaw frozen food, (1) leave the frozen food at room temperature to thaw, (2) thaw the frozen food in running water, or (3) put the frozen food in a cool box and keep it cool. One of the methods is to chill frozen food by circulating cold air near room temperature in the refrigerator. However, in the thawing method (1) that is left at room temperature, the food is easily thawed at room temperature, and the thawing method (2) that uses running water handles frozen foods in running water. It is complicated and troublesome, and the quality of the food may deteriorate due to running water.Therefore, in the method (3) that uses cold air close to normal temperature, body fluid leaching from the food body due to low freshness of the food, that is, drip Occurs, and the food is exposed to air of relatively low humidity, the surface of the food dries, and in any of the above methods (1) to (3), it is contained in the drip or in the food There is a problem that various substances contained in water or cooling water for generating cold air are apt to become unsanitary, such as being decomposed by bacteria and giving off a strange odor. Therefore, there is almost no known defrosting device that can thaw frozen foods while maintaining good hygiene.
【０００３】 一方、衛生状態を良好に保ちながら保冷できる装置としては、例えば、特開平 ４−２０７７８号公報に記載される装置が知られている。この装置では、保冷庫 の筐体内を冷却室とこの冷却室に連通する冷気ダクトとに区画し、冷気ダクトに 設けた冷水槽の冷水にオゾンガスを混入させてオゾン水とし、このオゾン水を循 環ポンプを介して冷気ダクト内に設けた散水ノズルから冷水槽に向かって噴出拡 散させ、冷気を殺菌、消臭するとともに、冷水槽の冷水を通過したオゾンガスの 一部を冷気とともに筐体内を循環させ、冷却室の食品に作用させて、食品の消毒 を行う構造が採られている。On the other hand, as a device capable of keeping cold while maintaining a good hygienic condition, for example, a device described in Japanese Patent Laid-Open No. 20778/1992 is known. In this device, the inside of the cool box is divided into a cooling chamber and a cold air duct communicating with this cooling chamber.Ozone gas is mixed with cold water in a cold water tank provided in the cold air duct to make ozone water, and this ozone water is circulated. A sprinkling nozzle provided in the cold air duct through a ring pump sprays and spreads it toward the cold water tank to sterilize and deodorize the cold air, and also to remove part of the ozone gas that has passed through the cold water in the cold water tank along with the cold air inside the housing It is circulated and acts on the food in the cooling room to disinfect the food.
【０００４】[0004]
しかしながら、上記従来の構造を有する特開平４−２０７７８号公報に記載さ れる保冷庫では、筐体内に冷水槽とオゾン発生装置を収納しているため、筐体寸 法が大きくなり、食品収容容積が少なくなり、利用効率が低下し、筐体内に複雑 な装置が配設されているため、装置の保守点検が困難になるとともに筐体内の食 品の取扱いに制約を生じるという問題点を有している。また、冷却室の食品と冷 水槽のオゾン水とがともに筐体内に収容されているため、食品が濃度の高いオゾ ンガスに直接曝され、オゾンの強い酸化作用にて食品表面が強く酸化され、変質 したり、変色が生じる場合があるという問題点を有している。さらに、加熱手段 が設けられていないため、冷凍食品を解凍する際に加熱することができず、解凍 時間を短縮できないという問題点を有している。 However, in the cool box described in JP-A-4-20778 having the above-mentioned conventional structure, since the cold water tank and the ozone generator are housed in the case, the size of the case becomes large, and the food storage volume is increased. However, it has a problem that the maintenance and inspection of the equipment is difficult and the handling of food in the enclosure is restricted because the complicated equipment is installed in the enclosure. ing. In addition, since the food in the cooling room and the ozone water in the cold water tank are both housed in the housing, the food is directly exposed to high-concentration ozone gas, and the strong oxidizing action of ozone strongly oxidizes the food surface. It has a problem that it may be deteriorated or discolored. Further, since no heating means is provided, there is a problem in that the frozen food cannot be heated when it is thawed, and the thawing time cannot be shortened.
【０００５】 なお、上記従来の特開平４−２０７７８号公報に記載される保冷庫では、オゾ ン水を散水ノズルから勢い良く噴出させる構造が採られているので、オゾン水を 冷気ダクト内に噴出させることはできるが、食品が収容されている冷却室内に直 接噴出させることはできない構造となっている。The conventional cool box described in Japanese Patent Laid-Open No. 20778/1992 has a structure in which ozone water is vigorously ejected from a water spray nozzle, so that ozone water is ejected into a cool air duct. However, the structure is such that it cannot be sprayed directly into the cooling chamber containing the food.
【０００６】 本考案は、上記問題点に鑑みなされたもので、解凍を短時間に簡単に行うこと ができ、食品の乾燥を防止でき、食品の鮮度を良好に保ち、異臭の発生を防止で き、食品の変質、変色を防止でき、しかも庫内の食品収容容積の大きな解凍保冷 庫を提供することを目的とする。The present invention has been made in view of the above problems, and is capable of thawing easily in a short time, preventing food from drying, maintaining good freshness of food, and preventing generation of offensive odor. In addition, it is an object of the present invention to provide a thawing cold storage box that can prevent the deterioration and discoloration of food and that has a large food storage capacity in the storage.

【００３０】 次に、本実施例の作用について説明する。Next, the operation of this embodiment will be described.
【００３１】 空気は、矢指Ａに示すように、第１の送風機６にて棚３間に送り込まれ、各ス リット４を経由し、ヒーター７および冷却用の熱交換機８を通過する際に解凍ま たは保冷に最適な温度に調節され、筐体１内を循環する。そして、この循環空気 に、棚3bに置かれた図示しない食品が曝されて、解凍保冷される。As shown by the arrow A, the air is sent between the shelves 3 by the first blower 6, passes through the slits 4, passes through the heater 7 and the heat exchanger 8 for cooling, and is thawed. Or, the temperature is adjusted to the optimum temperature for keeping cold, and circulates in the housing 1. Then, the food (not shown) placed on the shelf 3b is exposed to this circulating air to be thawed and kept cold.
【００３２】 なお、必要に応じて、前記仕切り壁体５と筐体１の間の下部に第２の送風機19 を設けると、この第２の送風機19にて各スリット４を経由した空気の上方への送 り込みを強化することができる。また、必要に応じて、棚３間を循環する風量を 均一化するため、下部に位置するスリット４の幅が大きくなるように、上下方向 に幅の勾配を付けてスリット４を形成してもよい。If a second blower 19 is provided in a lower portion between the partition wall body 5 and the housing 1 as needed, the second blower 19 can raise the air above each slit 4 through each slit 4.

Further, the mist of ozone water is condensed and the water accumulated at the bottom of the housing 1 is discharged from the drain port 11.
【００３５】 筐体内の温度調節については、まず、ヒーター７または冷却用の熱交換機８に て解凍に最適な温度に設定して所定時間解凍を行い、冷凍食品を所定温度まで解 凍した後に、熱交換機８にて保冷に最適な温度に設定し、食品が使用されるまで の間保冷を行う。このとき、筐体１、扉２のいずれも熱絶縁されているので、効 率良く解凍保冷を行える。なお、解凍から保存までの期間を通して、オゾン水の 霧を連続的に筐体１内に導入してもよいし、間欠的に必要量を導入してもよい。 また、解凍の際に、必要に応じて、前記クーラーをヒートポンプとし、熱交換 機８を通過する空気を加熱するヒーター運転を行って、解凍時間をさらに短縮し てもよい。Regarding the temperature control inside the housing, first, the temperature is set to the optimum temperature for thawing by the heater 7 or the heat exchanger 8 for cooling, and the frozen food is thawed for a predetermined time, and after the frozen food is thawed to a predetermined temperature, The heat exchanger 8 sets the optimum temperature for keeping cold and keeps it cold until the food is used. At this time, since the case 1 and the door 2 are both thermally insulated, it is possible to efficiently perform thawing and cooling. Note that the fog of ozone water may be continuously introduced into the housing 1 or intermittently a necessary amount may be introduced throughout the period from thawing to storage. When thawing, if necessary, the cooler may be used as a heat pump and a heater operation for heating the air passing through the heat exchanger 8 may be performed to further shorten the thawing time.
