Description

この発明は、筐体の前面および背面に開口部を有し、物品カートを一方の側から庫内へ搬入して消毒運転を行った後、該物品カートを他方の側から庫外へ搬出し得るパススルー式の消毒保管庫に関するものである。 The present invention has openings on the front and back surfaces of the housing, and after carrying the article cart into the refrigerator from one side and performing a disinfection operation, the article cart is carried out from the other side. It is about the pass-through type disinfection storage to be obtained.

例えば図１に示すように、食器洗いエリアＡに臨む筐体前面に食器カート１０が搬入される第１開口部１２および該開口部１２を閉成する第１扉１４が設けられ、また食品盛り付けエリアＢに臨む筐体背面に前記食器カート１０が搬出される第２開口部１６および該開口部１６を閉成する第２扉１８が設けられたパススルー式の消毒保管庫２０が、大型レストラン、病院その他学校等の厨房に広く使用されている。ここで、前記食器洗い場のようなエリアを便宜的に汚染エリアＡと称するが、これは単なる説明のためのものであって、衛生基準が劣っている訳ではない。また、食品盛り付け場のようなエリアを便宜的に清浄エリアＢと称するが、これとても衛生基準が格別優れているという訳ではない。唯、食器洗い場のような汚染エリアＡは、食品盛り付け場のような清浄エリアＢに比較すれば、一般に空気中の雑菌や塵埃等が相対的に多いと言うことができる。 For example, as shown in FIG. 1, a first opening 12 for carrying the tableware cart 10 and a first door 14 for closing the opening 12 are provided on the front surface of the housing facing the dishwashing area A, and a food serving area. A pass-through type disinfection storage 20 provided with a second opening 16 through which the tableware cart 10 is carried out and a second door 18 for closing the opening 16 on the back surface of the housing facing B is a large restaurant and a hospital. It is also widely used in kitchens such as schools. Here, the area such as the dishwashing place is referred to as a contaminated area A for convenience, but this is for the purpose of explanation only, and the hygiene standard is not inferior. In addition, an area such as a food serving area is referred to as a clean area B for convenience, but this does not mean that the hygiene standards are particularly excellent. However, it can be said that the contaminated area A such as a dishwashing place generally has a relatively large amount of germs and dust in the air as compared with the clean area B such as a food serving place.

この消毒保管庫２０は、図２に示すように、庫内に空気加熱用ヒーター２２と、該ヒーター２２で加熱された空気を熱風として庫内に循環させるファン２４とを備えている。そして、多数の食器籠２６を多段に載置した食器カート１０(図１０)を消毒保管庫２０の庫内に搬入した後、前記第１扉１４で第１開口部１２を、また第２扉１８で第２開口部１６を対応的に閉成して消毒運転を行う。すなわち、前記空気加熱用ヒーター２２と前記空気循環ファン２４とを作動させ、庫内に高温の熱風を循環させることにより、前記食器カート１０に載せた食器籠２６の食器を強制的に加熱乾燥させて高温殺菌が行われる。 As shown in FIG. 2, the disinfection storage 20 includes an air heating heater 22 and a fan 24 that circulates the air heated by the heater 22 as hot air in the storage. Then, after the tableware cart 10 (FIG. 10) in which a large number of tableware baskets 26 are placed in multiple stages is carried into the disinfection storage 20, the first door 14 opens the first opening 12 and the second door 2 doors. At 18, the second opening 16 is correspondingly closed and the disinfection operation is performed. That is, the tableware in the tableware basket 26 placed on the tableware cart 10 is forcibly heated and dried by operating the air heating heater 22 and the air circulation fan 24 to circulate high-temperature hot air in the chamber. High temperature sterilization is performed.

Then, as described above, after the tableware cart 10 is housed in the disinfection storage 20, the front and rear doors 14 and 18 are closed and the disinfection operation is performed, so that the tableware mounted on the tableware cart 10 is sterilized at a high temperature. To. Then, when the disinfection operation is completed, the second door 18 on the cleaning area B side is opened, the tableware cart 10 is carried out, and food is served at the serving place or the like in the cleaning area B. However, in this case, the first door 14 on the contaminated area A side may also be accidentally opened. Then, a contaminated atmosphere such as germs and dust floating in the contaminated area A invades the inside of the storage, adheres to the tableware that has just been disinfected, or recontaminates the inside of the storage. In addition, germs and dust in the contaminated area A may pass through the disinfection storage 20 and invade the clean area B, contaminating the atmosphere of the clean area B.

For this reason, it is possible to prevent the occurrence of erroneous operations such as the worker on the food serving place side accidentally stopping the operation even though the operation is started on the washing place side. Adjacent to the operation panel 30, a panel 32 for displaying the operating state of the disinfection storage 20 is provided. This is because in the pass-through type disinfection storage, the contaminated area A and the cleaning area B are separated by the storage, so that the worker working in one of the areas can open the door of the other area. Since it is not possible to confirm whether the door is closed or closed, the status display panel 32 is provided in order to eliminate the inconvenience. For example, even if the first door 14 is to be opened in the contaminated area A after the article cart 10 has been unloaded to the clean area B side, whether or not the article cart 10 has been unloaded is in the contaminated area A. The worker does not know. Therefore, in the case where the status display panel 32 is arranged, whether the first door 14 and the second door 18 are opened and closed, and whether the door is unlocked or locked by the first lock mechanism R1 and the second lock mechanism R2. Various information such as whether or not is displayed. In addition, instead of the state display panel 32, a plurality of lamps for identifying the operating state may be provided.

(経時的動作について)

物品カート１０を消毒保管庫２０の庫内へ搬入するときは、図５に示すように、第１扉１４を開放して該物品カート１０を庫内へ搬入する。このとき清浄エリアＢ側の第２扉１８は引き続き鎖錠されている。そして図６に示すように、消毒保管庫２０の庫内へ物品カート１０を完全に収納すると、庫内の赤外線送信部ＣＳ２からの赤外線が該物品カート１０に設けた赤外線受け部ＣＳ１に反応してカート完全収納を検知し、その検知信号を図９の制御回路２８に送る。そして、図８のタイムチャートに示すように、汚染エリアＡ側の第１扉１４を閉成すると、第１扉センサーＳＷ１が扉閉成を検知し、第１ロック機構Ｒ１がＯＮ作動して該第１扉１４を鎖錠する。この状態で空気加熱用ヒーター２２および空気循環ファン２４に通電され、消毒運転が開始される。 When the goods cart 10 is carried into the disinfection storage 20, the first door 14 is opened and the goods cart 10 is carried into the storage as shown in FIG. At this time, the second door 18 on the clean area B side is still locked. Then, as shown in FIG. 6, when the article cart 10 is completely stored in the disinfection storage 20, the infrared rays from the infrared transmitting unit CS2 in the storage react with the infrared receiving unit CS1 provided in the article cart 10. The cart is detected to be completely stored, and the detection signal is sent to the control circuit 28 of FIG. Then, as shown in the time chart of FIG. 8, when the first door 14 on the contaminated area A side is closed, the first door sensor SW1 detects the door closing, and the first lock mechanism R1 is turned on to operate the door. Lock the first door 14. In this state, the air heating heater 22 and the air circulation fan 24 are energized, and the disinfection operation is started.

所定時間の消毒運転が終了すると、図９の制御回路２８から第２ロック機構Ｒ２にＯＦＦ指令が出され、図７に示すように、清浄エリアＢ側の第２扉１８のロックが開錠される。そこで作業者が第２扉１８を開放して、消毒乾燥の終了した物品カート１０を清浄エリアＢ側へ搬出して食器の盛り付け等に供される。なお汚染エリアＡ側の第１扉１４における第１ロック機構Ｒ１の鎖錠は依然として継続しているので、該第１扉１４を開放することはできない。すなわち汚染エリアＡ側へ第１扉１４は開かないので、誤って第１扉１４を開放して汚染された雰囲気が庫内へ流入することがない。 When the disinfection operation for a predetermined time is completed, the control circuit 28 in FIG. 9 issues an OFF command to the second lock mechanism R2, and as shown in FIG. 7, the lock of the second door 18 on the cleaning area B side is unlocked. To. Therefore, the worker opens the second door 18 and carries out the article cart 10 that has been disinfected and dried to the cleaning area B side for serving tableware and the like. Since the locking of the first lock mechanism R1 at the first door 14 on the contaminated area A side is still ongoing, the first door 14 cannot be opened. That is, since the first door 14 is not opened toward the contaminated area A side, the first door 14 is not accidentally opened and the contaminated atmosphere does not flow into the refrigerator.
