Description

この発明は、冷凍機およびこの冷凍機を備えた消毒保管庫に関するものであって、更に詳細には、冷却効率を向上させると共に配置スペースおよび製造コストを抑え得る冷凍機と、外気を取り入れることなく密閉状態で、庫内の保管物を周囲温度にまで急速に冷却し得る消毒保管庫とに関するものである。 The present invention relates to a refrigerator and a disinfecting storage provided with the refrigerator, and more specifically, to a refrigerator that can improve cooling efficiency and reduce an arrangement space and manufacturing cost, and that does not take in outside air. The present invention relates to a disinfecting storage cabinet capable of rapidly cooling stored items in the cabinet to ambient temperature in a closed state.

病院や学校その他レストラン等の厨房施設では、水による洗浄が終わり水滴の付着している食器や箸、その他ナイフやフォーク等の金属什器(以下保管物という)を庫内に収納して、消毒状態で乾燥させる消毒保管庫が好適に使用されている。すなわち消毒保管庫は、電気ヒータに代表される加熱源と、該加熱源により加熱された空気を強制的に庫内に循環させる送風ファンとを備えて、水滴の付いた保管物を熱風で高温に加熱して殺菌消毒と乾燥とを行うものである。 In kitchen facilities such as hospitals, schools, and restaurants, tableware and chopsticks that have been washed with water and metal fixtures such as knives and forks (hereinafter referred to as stored items) that have water droplets are stored in the refrigerator and disinfected. A disinfecting storage that is dried at is preferably used. That is, the disinfection storage is equipped with a heating source typified by an electric heater and a blower fan for forcibly circulating the air heated by the heating source in the storage, so that the stored items with water drops are heated to high temperature with hot air. It is heated to sterilize and disinfect and dry.

図4は、一般的な消毒保管庫における正面の縦断面図であって、該消毒保管庫10は、外装と内装との間にグラスウールを充填した断熱構造の断熱箱体(箱体)12の内部に、所要の庫内空間14を保持して収納部16を配設した二重構造になっている。この収納部16は、その天板18の中央部に吸込口18aが形成されている。また収納部16の内部には、複数の棚板20が上下に所定間隔離間して多段に配置され、各棚板20に食器等の保管物(図示せず)を収容したカゴ22が載置される。 FIG. 4 is a vertical cross-sectional view of a front surface of a general disinfecting storage, and the disinfecting storage 10 includes a heat-insulating box body 12 having a heat insulating structure in which glass wool is filled between the exterior and interior. It has a double structure in which a required storage space 14 is held and a storage portion 16 is disposed inside. A suction port 18a is formed in a central portion of a top plate 18 of the storage section 16. In addition, a plurality of shelves 20 are vertically arranged at predetermined intervals in a multi-tiered manner inside the storage section 16, and a basket 22 accommodating stored items (not shown) such as dishes is placed on each shelf 20. To be done.

前記庫内空間14は、収納部16の天板上部に画成される上部空間14aと、前記収納部16の幅方向に対向する両側板24,24の外部に画成されて上部空間14aと連通する側部空間14b,14bと、断熱箱体12内に画成されて収納部16の下方に臨む底部空間14cとで構成されている。前記底部空間14cは、両側部空間14b,14bの下端に形成された吹出口26,26を介して相互に連通している。また収納部16は、上部空間14aに前記吸込口18aを介して連通すると共に、底部空間14cに連通し、更に側板24,24に形成した複数の通孔(図示せず)を介して側部空間14b,14bと連通している。 The interior space 14 is defined as an upper space 14a defined above the top plate of the storage unit 16 and an upper space 14a defined outside the side plates 24, 24 facing each other in the width direction of the storage unit 16. It is composed of side spaces 14b, 14b which communicate with each other, and a bottom space 14c which is defined in the heat insulating box 12 and faces below the storage section 16. The bottom space 14c communicates with each other through air outlets 26, 26 formed at the lower ends of the both side spaces 14b, 14b. Further, the storage portion 16 communicates with the upper space 14a through the suction port 18a, communicates with the bottom space 14c, and further through a plurality of through holes (not shown) formed in the side plates 24, 24. It communicates with the spaces 14b, 14b.

前記上部空間14aには送風ファン28が配設されると共に、該上部空間14aには、送風ファン28に近接して加熱源である電気ヒータ30が配置してある。前記送風ファン28は、収納部16の吸込口18aから空気を上部空間14aに吸込み、該空気を電気ヒータ30に接触させる。従って送風ファン28を運転すると、収納部16側から吸込んだ空気は、電気ヒータ30に加熱されて熱風になった後、前記両側部空間14b,14bへ流入する。そして熱風は、前記側板24の通孔および吹出口26,26から収納部16の内部へ吹込まれ、収納されている保管物を加熱する。前記消毒保管庫10には、図4に示す如く、筐体天板36に開口部38が開設され、この開口部38に前記収納部16を介して外気を導入する排気ダクト32が設けられている。この排気ダクト32にはダンパ34が開閉自在に配設され、該ダンパ34によって閉成または開放される。すなわち、ダンパ34を閉じて排気ダクト32を閉成したときには、収納部16内の湿気が外部に排出されることなく食器が加熱されて該食器の消毒がなされる。また、排気ダクト32のダンパ34を開放したときには、収納部16内の湿気は庫内空間14および開口部38を介して外部に排出されつつ保管物が加熱されて該保管物の乾燥がなされる。 A blower fan 28 is arranged in the upper space 14a, and an electric heater 30 as a heating source is arranged in the upper space 14a close to the blower fan 28. The blower fan 28 sucks air into the upper space 14a from the suction port 18a of the storage section 16 and brings the air into contact with the electric heater 30. Therefore, when the blower fan 28 is operated, the air sucked from the storage portion 16 side is heated by the electric heater 30 to become hot air, and then flows into the both side spaces 14b, 14b. Then, the hot air is blown into the inside of the storage portion 16 from the through holes of the side plate 24 and the outlets 26, 26 to heat the stored items stored therein. As shown in FIG. 4, in the disinfecting storage 10, an opening 38 is opened in the top plate 36 of the housing, and an exhaust duct 32 for introducing outside air through the storage 16 is provided in the opening 38. There is. A damper 34 is openably and closably arranged in the exhaust duct 32, and is closed or opened by the damper 34. That is, when the damper 34 is closed and the exhaust duct 32 is closed, the tableware is heated and the tableware is sterilized without the moisture in the storage section 16 being discharged to the outside. Further, when the damper 34 of the exhaust duct 32 is opened, the moisture in the storage portion 16 is discharged to the outside through the internal space 14 and the opening portion 38, and the stored material is heated to dry the stored material. ..

このように消毒保管庫は、保管物を乾燥する過程で乾燥消毒するので極めて衛生的である。ところで厨房施設等では、乾燥消毒が終了したら直ぐに保管物を取り出して、次の配膳に使いたい、という需要が存在する。しかし乾燥終了直後の保管物は高温状態であるので、この保管物に冷たい料理を盛り付ける等の配膳には適さない。また、熱い状態の保管物を運搬する際には火傷しないよう、作業者は充分注意を払わねばならない。そこで乾燥終了後に、保管物を消毒保管庫から冷蔵庫へ移し替えて冷却したり、該保管物を台車式のカートに移載した後、このカートごと冷蔵プレハブ庫へ搬入して冷却したりする作業を行っている。 As described above, the disinfection storage is extremely hygienic because it is dried and disinfected in the process of drying the stored material. By the way, in kitchen facilities and the like, there is a demand for removing stored items immediately after drying and disinfecting and using them for the next serving. However, since the stored items immediately after drying are in a high temperature state, they are not suitable for serving such as serving cold dishes. In addition, workers must take great care to prevent burns when transporting hot items. Therefore, after drying, transfer the stored items from the disinfecting storage to the refrigerator for cooling, or transfer the stored items to a cart with a cart, and then carry the entire cart into a refrigerated prefab to cool it. It is carried out.

しかし、前記の如く保管物を消毒保管庫から冷蔵庫へ移載したり、該保管物をカートごと冷蔵プレハブ庫へ搬入させるのは、煩雑な移し替え作業や余分な設備投資を必要とする難点がある。このため、加熱乾燥機能に加えて冷却機能を付帯させ、同一庫内で保管物の加熱乾燥をした後に、該保管物を配膳に必要な温度まで冷却する消毒保管庫が実用化されている。例えば、特開2017−113239号公報や特開2003−310527号公報に開示の冷却機能付き消毒保管庫がそれであって、何れも庫内に外部空気を取り入れて一次冷却を行った後に、冷凍機により二次冷却を行うものである。このように一次冷却を行う理由は、冷凍機の容量が大きくなる(過大負荷になる)のを避けて、設備費用が嵩むのを抑制するためである。 However, transferring the stored items from the disinfecting storage to the refrigerator or carrying the stored items together with the cart into the refrigerated prefabricated storage box as described above has a drawback that complicated transfer work and extra capital investment are required. is there. For this reason, a disinfecting storage cabinet has been put into practical use in which a cooling function is additionally provided in addition to the heating and drying function, and the storage article is heated and dried in the same cabinet, and then the stored article is cooled to a temperature necessary for serving. For example, the disinfecting storage cabinets with a cooling function disclosed in JP-A-2017-113239 and JP-A-2003-310527 are examples thereof, and both of them are provided with external air to perform primary cooling and then a refrigerator. The secondary cooling is performed by. The reason for performing the primary cooling in this manner is to prevent the capacity of the refrigerator from becoming large (excessive load) and to suppress an increase in equipment cost.

特開2017−113239号公報JP, 2017-113239, A

前述のように、冷却機能付きの消毒保管庫10は外部空気を庫内へ導入して一次冷却しているが、冷却媒体が空気であるために保管物の冷却に時間を要する難点がある。また、庫内に取り入れられる外部空気は浮遊菌(雑菌)や埃その他夾雑物を含んでいるから、消毒した保管物を再汚染することになる。このため、消毒保管庫10の前記開口部38に細かいメッシュのフィルタを配置しているが、圧力損失を生じて外部空気の取込み量が減少して一次冷却の効果が低下する恐れがある。またフィルタを定期交換したり、前記開口部38に前記ダンパ34を設けたりする必要があって、製作費用や維持費用が嵩む難点も指摘される。 As described above, the disinfecting storage cabinet 10 with a cooling function introduces external air into the cabinet for primary cooling. However, since the cooling medium is air, it takes a long time to cool the stored article. In addition, since the external air taken into the storage contains airborne bacteria (miscellaneous bacteria), dust and other contaminants, it will recontaminate the sterilized stored items. For this reason, a fine mesh filter is arranged in the opening 38 of the disinfecting storage 10, but there is a risk that pressure loss will occur and the amount of external air taken in will decrease, reducing the effect of primary cooling. It is also pointed out that it is necessary to periodically replace the filter and to provide the damper 34 in the opening 38, which causes a problem that manufacturing cost and maintenance cost increase.

また、従来の冷凍機における冷凍系は、圧縮機と凝縮器と冷媒膨張手段と蒸発器とから構成されているが、その他に圧縮機を使用しないで、凝縮器と蒸発器との位置的な高低差並びに該凝縮器での温度差を利用して冷媒を循環させるループ型サーモサイホン方式の冷凍機が存在する。そして、これら2つの異なる冷凍機を物品保管庫に併設して、求められる冷凍状態に応じて何れかの冷凍機を使い分けることが提案されている。しかし、この2つの冷凍機を併用するときは、凝縮器および蒸発器が夫々に必要になって配置スペースが大きくなり、また製造コストが嵩む難点がある。 Further, the refrigeration system in the conventional refrigerator is composed of a compressor, a condenser, a refrigerant expansion means, and an evaporator, but other compressors are not used, and the positional relationship between the condenser and the evaporator is fixed. There is a loop-type thermosiphon refrigerator that circulates a refrigerant by utilizing the height difference and the temperature difference in the condenser. Then, it has been proposed that these two different refrigerators be installed side by side in an article storage, and one of the refrigerators is used properly according to the required frozen state. However, when these two refrigerators are used in combination, a condenser and an evaporator are required for each, so that the arrangement space becomes large and the manufacturing cost increases.

前記課題を解決し、所期の目的を達成するため請求項3に記載の発明は、
加熱源と送風ファンとを備え、熱風を庫内に循環させて保管物を消毒保管する消毒保管庫において、
前記消毒保管庫の内部に配置した蒸発器と、前記消毒保管庫の外部に設けられ、かつ前記蒸発器よりも上方に配置した凝縮器と、前記蒸発器と前記凝縮器とをループ状に連結すると共に、内部に封入した冷媒を温度差により該蒸発器および該凝縮器の間で循環させる冷媒循環路とからなる冷却系が設けられ、この冷却系により前記庫内を冷却するようにしたことを要旨とする。

In order to solve the above problems and achieve the intended purpose, the invention according to claim 3 is
In a disinfecting storage that includes a heating source and a blower fan, circulates hot air in the storage to disinfect and store stored items,
An evaporator disposed inside the disinfecting storage, a condenser disposed outside the disinfecting storage and disposed above the evaporator, and the evaporator and the condenser connected in a loop. In addition, a cooling system including a refrigerant circulation path that circulates the refrigerant sealed inside between the evaporator and the condenser due to a temperature difference is provided, and the inside of the refrigerator is cooled by this cooling system. Is the gist.
According to the invention of claim 3, when the operation is switched to the cooling operation, it is not necessary to take in the outside air into the refrigerator for the primary cooling, so that the stored items such as tableware are re-contaminated by various bacteria and fine dust in the air. There is an advantage that the stored material can be stored hygienically in a disinfected state without being damaged. Also, in the loop type thermosiphon method, the higher the temperature inside the chamber after disinfection/drying, the higher the speed of the refrigerant circulating between the evaporator and the condenser (heat transfer efficiency is good), so the outside air is taken in. Therefore, the cooling time can be shortened as compared with the conventional method of primary cooling.

請求項4に記載の発明では、前記蒸発器の下方にドレンパンを配置すると共に、該ドレンパンに排水管を連通接続し、該蒸発器に凝縮して滴下する結露水をドレンパンおよび排水管を介して庫外へ排出することを要旨とする。
請求項4に係る発明によれば、ループ型サーモサイホン方式を採用した際に、水蒸気が蒸発器に凝縮して結露し滴下するが、滴下した水滴はドレンパンを介して庫外へ排出される。このため、水蒸気を排出するための排気ダクトやダンパを不要になし得る。また、水蒸気が庫外へ逃出することがないので、消毒保管庫を設置した個所の天井等に結露を生ずることがなく、設置場所に制約を受けない。また、水蒸気が庫外へ逃出しないために周囲の温度や湿度を上げることがなく、設置環境を良好に保ち得る。
In the invention according to claim 4, a drain pan is arranged below the evaporator, and a drain pipe is connected to the drain pan so that condensed water condensed and dropped in the evaporator is drained through the drain pan and the drain pipe. The main point is to discharge it outside the refrigerator.
According to the invention of claim 4, when the loop type thermosiphon system is adopted, the water vapor condenses in the evaporator to form dew drops, but the dropped water drops are discharged to the outside of the refrigerator via the drain pan. Therefore, it is possible to eliminate the need for an exhaust duct or a damper for discharging water vapor. Further, since the steam does not escape to the outside of the storage, there is no dew condensation on the ceiling or the like of the place where the disinfection storage is installed, and the installation location is not restricted. Further, since the water vapor does not escape to the outside of the refrigerator, the ambient temperature and humidity are not raised, and the installation environment can be kept good.

冷却運転に切り替えた際に、一次冷却のため外気を庫内へ取り入れる必要がないので、食器等の保管物が空中の雑菌や微細な埃により再汚染されることがなく、保管物を消毒状態のまま衛生的に保管し得る。また、ループ型サーモサイホン方式は、消毒・乾燥後の庫内温度が高いほど蒸発器と凝縮器との間を循環する冷媒の速度が大きくなるから、外気を取り込んで一次冷却する在来の方式に比べて冷却時間を短縮することができる。また、第1冷却系と第2冷却系とを備える冷凍機では、2つの冷却系において凝縮器と蒸発器とを共用できるので配置スペースが小さくなり、製造コストを抑えることができる。 When switching to cooling operation, it is not necessary to take in outside air into the refrigerator for primary cooling, so stored items such as tableware are not re-contaminated by bacteria in the air and fine dust, and stored items are disinfected. It can be stored sanitarily as it is. In addition, the loop-type thermosiphon method is a conventional method that takes in the outside air and performs primary cooling because the speed of the refrigerant circulating between the evaporator and the condenser increases as the temperature inside the chamber after disinfection/drying increases. The cooling time can be shortened as compared with. Further, in the refrigerator provided with the first cooling system and the second cooling system, since the condenser and the evaporator can be shared by the two cooling systems, the arrangement space becomes small and the manufacturing cost can be suppressed.

An on-off valve V1 (also referred to as a first on-off valve) is provided in a refrigerant circulation path 40 that connects the refrigerant outlet side of the condenser CD and the refrigerant inlet side of the evaporator EVA to evaporate from the condenser CD. It is possible to control the cutoff/communication of the refrigerant to the container EVA.

前記蒸発器EVAと凝縮器CDとを冷媒循環路40で連通した冷凍機(第1冷却系)を、一般にループ型サーモサイホン方式という。このループ型サーモサイホン方式は、前記冷媒循環路40に封入した冷媒を、凝縮器CDと蒸発器EVAとの高低差および温度差で循環させて蒸発器EVAにより庫内を冷却するものであって、冷媒を強制循環させるための圧縮機を必要としない静的クローズドループになっている。すなわち、消毒保管庫10の加熱運転を行うと、加熱源である電気ヒータ30と送風ファン28とにより熱風が庫内を循環する。このため、加熱運転を終了した直後の庫内は予熱で充分高温(例えば80℃)になっており、前記高温環境に晒された庫内上方の蒸発器EVAもかなり温度が高くなっている。そこで、加熱運転から冷却運転に切り替って前記開閉弁V1が開放すると、冷媒循環路40に封入した冷媒は高低差により凝縮器CDから蒸発器EVAに流入する。このとき蒸発器EVAの温度は高くなっているので、該蒸発器EVAを通過する冷媒は高い効率で気化し、蒸発器EVAによる冷却機能を発揮して保管物の冷却を行う。蒸発器EVAを出て軽くなった気化冷媒は冷媒循環路40を上昇して凝縮器CDに帰還し、ここで凝縮され液化した冷媒は再び蒸発器EVAに戻るサイクルを反復する。この冷媒循環サイクルが所謂ループ型のサーモサイホンであって、庫内温度が高いほど庫外温度との温度差が付いて熱輸送能力が向上し、急速に庫内を冷却することができる。このように実施例の消毒保管庫10は、その冷却系(第1冷却系)として前記ループ型サーモサイホン方式を採用したので、外気を庫内に取り入れて一次冷却する必要がない。従って、庫内を密閉したまま冷却できるため、空気中の浮遊菌や埃が侵入せず、保管物を衛生的に保管することができる。 The refrigerator (first cooling system) in which the evaporator EVA and the condenser CD are connected by the refrigerant circulation path 40 is generally called a loop thermosiphon system. In this loop type thermosiphon system, the refrigerant enclosed in the refrigerant circulation path 40 is circulated at a height difference and a temperature difference between the condenser CD and the evaporator EVA to cool the inside of the refrigerator by the evaporator EVA. , It is a static closed loop that does not require a compressor for forced circulation of the refrigerant. That is, when the heating operation of the disinfecting storage 10 is performed, hot air is circulated in the storage by the electric heater 30 which is a heating source and the blower fan 28. For this reason, the inside of the refrigerator immediately after the heating operation is preheated to a sufficiently high temperature (for example, 80° C.), and the evaporator EVA above the inside of the refrigerator exposed to the high temperature environment also has a considerably high temperature. Therefore, when the opening/closing valve V1 is opened by switching from the heating operation to the cooling operation, the refrigerant enclosed in the refrigerant circulation path 40 flows from the condenser CD into the evaporator EVA due to the height difference. At this time, since the temperature of the evaporator EVA is high, the refrigerant passing through the evaporator EVA is vaporized with high efficiency, and the cooling function of the evaporator EVA is exerted to cool the stored items. The vaporized refrigerant that has left the evaporator EVA and becomes lighter rises in the refrigerant circulation path 40 and returns to the condenser CD, where the condensed and liquefied refrigerant returns to the evaporator EVA again. This refrigerant circulation cycle is a so-called loop type thermosiphon, and the higher the temperature inside the refrigerator, the higher the temperature difference from the temperature outside the refrigerator, and the higher the heat transport capacity, and the faster the inside can be cooled. As described above, since the disinfecting storage cabinet 10 of the embodiment adopts the loop type thermosiphon system as the cooling system (first cooling system), it is not necessary to take in outside air into the cabinet for primary cooling. Therefore, since the inside of the refrigerator can be cooled while being sealed, suspended microorganisms and dust in the air do not enter, and the stored items can be stored hygienically.

(変形例)
図1の消毒保管庫10には、その変形例として符号42で示すドレンパンと符号44で示す排水管とが配設されている。すなわち消毒保管庫では、水による洗浄が済んで濡れた状態の保管物を加熱乾燥させるため、加熱運転中に水滴が蒸発して多量の水蒸気が発生する。この高温の水蒸気は熱伝達性が良いので、保管物の高温殺菌による消毒が併せて行われる。前記消毒を終えた水蒸気は不要であるので、図4に示す消毒保管庫10の上面に設けた前記ダンパ34を開放して、筐体天板36に開設した開口部38から該水蒸気を外部へ排出する。すなわち、保管物に付着した水分が気化して水蒸気になると、体積膨張により庫内の圧力(内圧)が上昇するため、水蒸気は庫内の空気と共に自然に前記開口部38から排出される。しかし前記開口部38は、前記ダンパ34が存在するとはいえ、外部に連通しているから、消毒後の庫内を引き続き衛生的に保つためには、該開口部38を設けないのが望ましい。
(Modification)
As a modified example thereof, the drain pan shown by reference numeral 42 and the drainage pipe shown by reference numeral 44 are arranged in the disinfecting storage box 10 of FIG. That is, in the disinfecting storage, the stored material that has been washed with water and wet is dried, so that water droplets evaporate and a large amount of water vapor is generated during the heating operation. Since this high-temperature steam has a good heat transfer property, the stored material is also sterilized by high-temperature sterilization. Since the steam that has been disinfected is unnecessary, the damper 34 provided on the upper surface of the disinfecting storage 10 shown in FIG. Discharge. That is, when the water attached to the stored material is vaporized to become water vapor, the pressure (internal pressure) in the refrigerator rises due to volume expansion, so that the steam is naturally discharged from the opening 38 together with the air in the refrigerator. However, even though the damper 34 is present, the opening 38 communicates with the outside, and therefore it is desirable not to provide the opening 38 in order to keep the inside of the chamber after disinfection hygienic.

図1に示す変形例は、前記開口部38およびダンパ34を設けることなく、水蒸気を外部へ排出する代替手段を提案したものである。すなわち、消毒保管庫10が冷却運転に入ると前記開閉弁V1が開放して、凝縮器CDからの冷媒を自重により前記蒸発器EVAへ流入させて庫内冷却を行う。蒸発器EVAの表面は庫内温度よりかなり低いために、水蒸気は該蒸発器EVAの表面に凝縮して結露し、自重により次々と滴下する。そこで、前記蒸発器EVAの下方に受け皿としてのドレンパン42を配置すると共に、該ドレンパン42の底面に排水管44を連通接続するようにした。 The modification shown in FIG. 1 proposes an alternative means for discharging water vapor to the outside without providing the opening 38 and the damper 34. That is, when the disinfection storage box 10 enters the cooling operation, the on-off valve V1 is opened, and the refrigerant from the condenser CD is caused to flow into the evaporator EVA by its own weight to cool the inside of the box. Since the surface of the evaporator EVA is considerably lower than the temperature inside the refrigerator, the water vapor condenses on the surface of the evaporator EVA to cause dew condensation, and drops one after another due to its own weight. Therefore, a drain pan 42 as a tray is arranged below the evaporator EVA, and a drain pipe 44 is connected to the bottom surface of the drain pan 42 for communication.

これにより、蒸発器EVAに結露して滴下する水滴は前記ドレンパン42に回収され、該ドレンパン42に回収された水は前記排水管44を介して外部へ排出される。なお、前記ドレンパン42は排水管44を介して外部に連通しているが、該排水管44の開口面積は小さく、しかも庫内は水蒸気により内圧が高まっているから、外気が侵入する懸念は殆どない。この構造によれば、外気侵入による保管物の再汚染がなく、しかも前記排気口や排気ダンパを要しないために、製造コストを抑制し得る利点がある。 As a result, water droplets that condense on the evaporator EVA and drip are collected in the drain pan 42, and the water collected in the drain pan 42 is discharged to the outside via the drain pipe 44. The drain pan 42 communicates with the outside through a drain pipe 44. However, since the opening area of the drain pipe 44 is small and the internal pressure of the inside of the storage chamber is increased by the steam, there is almost no possibility that outside air will enter. Absent. According to this structure, there is no recontamination of stored items due to invasion of outside air, and since the exhaust port and the exhaust damper are not required, there is an advantage that the manufacturing cost can be suppressed.

(別実施例について)
図1に関して説明したループ型サーモサイホン方式の第1冷却系を採用した冷凍機は、小型でありながら熱輸送能力が高く、しかも圧縮機を要しないという利点がある。また、蒸発器EVAの周囲温度と凝縮器CDの周囲温度との温度差が大きいほど熱輸送能力は向上するので、庫内が高温になっている温度域から徐々に冷却するのに本発明は大きな威力を発揮する。しかし、庫内を高温域から冷温域まで長い時間をかけることなく冷却させたい場合(急速冷却)は、ループ型サーモサイホン方式の冷却系だけでは対処しきれないこともある。
(About another example)
The refrigerator adopting the first cooling system of the loop type thermosiphon system described with reference to FIG. 1 has advantages that it is small in size, has a high heat transport capacity, and does not require a compressor. In addition, the larger the temperature difference between the ambient temperature of the evaporator EVA and the ambient temperature of the condenser CD is, the more the heat transfer capacity is improved. Demonstrate great power. However, when it is desired to cool the inside of the refrigerator from the high temperature region to the low temperature region without taking a long time (rapid cooling), the loop type thermosiphon cooling system may not be sufficient.

このような場合には、ループ型サーモサイホン方式の第1冷却系で庫内を一次冷却した後に、圧縮機を使用した第2冷却系で二次冷却する方が効率的である。しかし、ループ型サーモサイホン方式の第1冷却系と圧縮機を使用した第2冷却系との夫々に、独立した凝縮器CDおよび蒸発器EVAを個別に設けることは極めて不経済である。また、2つの独立した冷却系を併設すると必然的に配置スペースが大きくなり、消毒保管庫10を設置する場所を選ぶ必要がある。 In such a case, it is more efficient to first cool the inside of the refrigerator by the first cooling system of the loop type thermosiphon system and then perform the second cooling by the second cooling system using the compressor. However, it is extremely uneconomical to separately provide an independent condenser CD and an evaporator EVA in each of the first cooling system of the loop type thermosiphon system and the second cooling system using the compressor. In addition, if two independent cooling systems are provided side by side, the arrangement space inevitably becomes large, and it is necessary to select a place where the disinfection storage cabinet 10 is installed.

そこで本発明は、消毒保管庫10にループ型サーモサイホン方式の第1冷却系と圧縮機を使用した第2冷却系とを併用する際に、図2および図3に示す如く、凝縮器CD、蒸発器EVAおよび一部の冷媒循環用の管路を2つの冷却系に共用し、弁体の切り替えで何れかの冷却系を選択し得るようにしたものである。すなわち、庫内が高温域のときはループ型サーモサイホン方式の第1冷却系により一次冷却し、庫内温度がある程度まで下がったら圧縮機を使用した第2冷却系で二次冷却することで、全体として急速冷却を達成し得る。例えば、80℃から50℃まではループ型サーモサイホン方式の第1冷却系を使用し、50℃から10℃までは圧縮機を有する第2冷却系を使用するようにして、1つの冷却回路で機能を使い分けるものである。 Therefore, according to the present invention, when the loop type thermosiphon type first cooling system and the second cooling system using the compressor are used together in the disinfecting storage 10, as shown in FIGS. 2 and 3, the condenser CD, The evaporator EVA and a part of the pipeline for circulating the refrigerant are shared by the two cooling systems, and one of the cooling systems can be selected by switching the valve element. That is, when the inside of the refrigerator is in a high temperature range, primary cooling is performed by the first cooling system of the loop type thermosiphon system, and when the temperature of the inside is lowered to a certain degree, secondary cooling is performed by the second cooling system using the compressor. Overall, rapid cooling can be achieved. For example, from 80° C. to 50° C., the first cooling system of the loop type thermosiphon system is used, and from 50° C. to 10° C., the second cooling system having the compressor is used. Different functions are used.

次に、第1冷却系と第2冷却系とを切り替える具体例を説明する。図2は、2つの冷却系を1つの冷却回路に集約したもので、ループ型サーモサイホン方式の第1冷却系を運転する一方で、圧縮機使用の第2冷却系は停止させた場合を示している。すなわち図2および図3において、前述したループ型サーモサイホン方式の第1冷却系とは別に、圧縮機CMを使用する第2冷却系が1つの冷却回路に併設されている。そして第1冷却系および第2冷却系は、前記凝縮器CDと蒸発器EVAの双方を共用している。ここで、ループ型サーモサイホン方式の第1冷却系は図1に関して説明した通りであるが、第2冷却系は筐体天板36の上部に圧縮機CMを備えている。 Next, a specific example of switching between the first cooling system and the second cooling system will be described. FIG. 2 shows a case where two cooling systems are integrated into one cooling circuit and the first cooling system of the loop type thermosiphon system is operated while the second cooling system using the compressor is stopped. ing. That is, in FIG. 2 and FIG. 3, in addition to the first cooling system of the loop type thermosiphon system described above, a second cooling system using the compressor CM is provided in one cooling circuit. The first cooling system and the second cooling system share both the condenser CD and the evaporator EVA. Here, the first cooling system of the loop type thermosiphon system is as described with reference to FIG. 1, but the second cooling system is provided with the compressor CM above the housing top plate 36.

例えば凝縮器CDの冷媒出口は、第1冷却系の冷媒循環路40に連通接続していると共に、これとは別に第2冷却系の冷媒循環路46に連通接続している。この冷媒出口側の冷媒循環路46は、第2開閉弁V2および膨張弁EVを介して前記蒸発器EVAの冷媒流入側に連通接続している。また、蒸発器EVAの冷媒流出側は、第1冷却系の冷媒循環路40に接続すると共に、第2冷却系の冷媒循環路46にも接続している。そして冷媒流出側の前記冷媒循環路46は、第3開閉弁V3を介して前記圧縮機CMに連通接続し、該圧縮機CMの冷媒流出側は凝縮器CDの冷媒流入側に連通接続している。 For example, the refrigerant outlet of the condenser CD is connected to the refrigerant circulation passage 40 of the first cooling system, and separately connected to the refrigerant circulation passage 46 of the second cooling system. The refrigerant circulation path 46 on the refrigerant outlet side is connected to the refrigerant inflow side of the evaporator EVA via the second opening/closing valve V2 and the expansion valve EV. Further, the refrigerant outflow side of the evaporator EVA is connected to the refrigerant circulation path 40 of the first cooling system and is also connected to the refrigerant circulation path 46 of the second cooling system. The refrigerant circulation path 46 on the refrigerant outflow side is connected to the compressor CM via the third on-off valve V3, and the refrigerant outflow side of the compressor CM is connected to the refrigerant inflow side of the condenser CD. There is.

このような構成において、図2はループ型サーモサイホン方式の第1冷却系における第1開閉弁V1を開放することで、冷媒を高低差に伴う自重により落下させ冷媒循環路40を介して前記蒸発器EVAへ供給し、第1冷却系による庫内冷却を行っている。このとき、第2冷却系における前記第2開閉弁V2および第3開閉弁V3は何れも閉じているので、冷媒循環路46での冷媒循環は停止している。 In such a configuration, as shown in FIG. 2, by opening the first opening/closing valve V1 in the first cooling system of the loop type thermosiphon system, the refrigerant is dropped by its own weight due to the height difference and the evaporation is performed via the refrigerant circulation path 40. It is supplied to the container EVA, and the inside of the refrigerator is cooled by the first cooling system. At this time, since both the second opening/closing valve V2 and the third opening/closing valve V3 in the second cooling system are closed, the refrigerant circulation in the refrigerant circulation path 46 is stopped.

図3に示す冷却回路では、第1冷却系の第1開閉弁V1を閉じて冷媒供給を停止している。また、第2冷却系の圧縮機CMを起動すると共に第2開閉弁V2および第3開閉弁V3を開放し、更に前記膨張弁EVを開放することで、前記蒸発器EVAに冷媒を供給している。すなわち第1冷却系は停止し、第2冷却系が運転されて庫内冷却を行っている。 In the cooling circuit shown in FIG. 3, the first on-off valve V1 of the first cooling system is closed to stop the refrigerant supply. Further, the refrigerant CM is supplied to the evaporator EVA by starting the compressor CM of the second cooling system, opening the second opening/closing valve V2 and the third opening/closing valve V3, and further opening the expansion valve EV. There is. That is, the first cooling system is stopped and the second cooling system is operated to cool the inside of the refrigerator.

このように図2および図3に示す消毒保管庫10によれば、ループ型サーモサイホン方式の第1冷却系と圧縮機を有する第2冷却系とを併設することで、加熱運転が終了した後に庫内の保管物を冷却する時間を短縮できる。すなわち、第2冷却系だけでは対応困難な高負荷冷却を第1冷却系で行えるために急速に冷却することが可能になった。しかも、ループ型サーモサイホン方式の第1冷却系と圧縮機を有する第2冷却系とで凝縮器CD、蒸発器EVAおよび一部の冷媒循環用配管を共用できるために、製作コストを低減し得ると共に、2系統の冷凍機を併設しても装置の小型化を図ることができる。 As described above, according to the disinfecting storage 10 shown in FIGS. 2 and 3, the loop type thermosiphon type first cooling system and the second cooling system having the compressor are provided side by side so that the heating operation is completed. It is possible to shorten the time for cooling the stored items in the refrigerator. That is, high-load cooling, which is difficult to deal with only by the second cooling system, can be performed by the first cooling system, so that rapid cooling is possible. Moreover, since the condenser CD, the evaporator EVA, and a part of the refrigerant circulation pipe can be shared by the first cooling system of the loop type thermosiphon system and the second cooling system having the compressor, the manufacturing cost can be reduced. At the same time, it is possible to reduce the size of the device even if two refrigerators are provided side by side.

(棚構造について)
消毒保管庫における保管物は、前述したように一般的に食器や箸その他スプーン等の金属什器であるが、用途によってはフードスライサーの円盤刃を消毒して保管することもある。この円盤刃を消毒保管庫や、乾燥消毒機能のない専用の保管庫で保管するには、図5に示すように、保管庫52の対向する両内壁に所要間隔で多段に設けた一対の断面L字型の棚受け48,48により、該円盤刃50を両側から支持するようになっている。
(About shelf structure)
The stored items in the disinfecting storage are generally metal utensils such as tableware, chopsticks and spoons as described above, but depending on the application, the disc blade of the food slicer may be disinfected and stored. In order to store this disc blade in a disinfecting storage or a dedicated storage without a drying and disinfecting function, as shown in FIG. 5, a pair of cross-sections provided on both inner walls of the storage 52 facing each other in multiple stages at required intervals. The disk blade 50 is supported from both sides by L-shaped shelf receivers 48, 48.

しかし、保管庫52の庫内横幅が特定の円盤刃50の直径寸法に相応したものであれば、前記棚受け48,48の幅方向の間隔は小さくて済み、該円盤刃50が載置される位置に大きなずれを生じない。しかしながら、円盤刃50は、その用途に応じて直径が異なり得るので、直径寸法の異なる種々の円盤刃50に対応した横幅寸法の保管庫52を個別に準備しておくことは、不経済であって現実的でない。 However, if the horizontal width of the storage cabinet 52 corresponds to the diameter dimension of the specific disc blade 50, the space between the shelf receivers 48, 48 in the width direction can be small, and the disc blade 50 can be placed. There is no large deviation in the position. However, since the disc blade 50 may have different diameters depending on its use, it is uneconomical to separately prepare the storage cabinets 52 having the width dimensions corresponding to the disc blades 50 having different diameter dimensions. Is not realistic.

そこで左右で一対になる前記棚受け48,48の少なくとも一方だけを、図6に示すように、横幅Lを大きくすることで、ある程度寸法差がある各種円盤刃50であっても載置保持できるようにした。すなわち図7に示すように、例えば左側の棚受け48の横幅よりも右側の棚受け48の横幅L1を大きく設定することで、円盤刃50を両棚受け48,48に載置した際に自然に中央に収まって安定する。また棚受け48の横幅を大きくすることで強度が向上すると共に、板厚を薄く抑えることができる。更に、円盤刃50を両棚受け48,48に載置した際に中央付近に収納されるため、整頓状態になって見映えが良い。なお、円盤刃50の直径が比較的小さい場合は、図7の左側に位置する棚受け48の横幅L2も大きく設定することで、該円盤刃50の載置位置は中央へ誘導され一層好ましい。 Therefore, by increasing the lateral width L of at least one of the rack receivers 48, 48 that are paired on the left and right, it is possible to mount and hold even various disk blades 50 having a certain dimensional difference. I did it. That is, as shown in FIG. 7, for example, by setting the lateral width L1 of the right shelf receiver 48 to be larger than the lateral width of the left shelf receiver 48, the disk blade 50 is naturally placed on both shelf receivers 48, 48. It fits in the center and stabilizes. Further, by increasing the width of the shelf receiver 48, the strength can be improved and the plate thickness can be reduced. Further, when the disc blade 50 is placed on both shelf receivers 48, 48, it is housed in the vicinity of the center, so that it is neat and has a good appearance. When the diameter of the disc blade 50 is comparatively small, it is more preferable to set the lateral width L2 of the shelf receiver 48 located on the left side of FIG.
