Description

本発明は、一群の食品トレイが搭載されたカートを収納した状態で、食品トレイ上の食品に対して冷却処理あるいは加熱処理を行うカート棚式の食品加工装置に関する。 The present invention relates to a cart shelf type food processing apparatus that performs cooling treatment or heat treatment on food on a food tray in a state where a cart on which a group of food trays is mounted is stored.

この種の食品加工装置において、一群の食品トレイが搭載されたカートを庫内に収容して、カートごと冷却処理や加熱処理を行うことは、例えば、特許文献１に記載の貯蔵庫に公知である。そこでは、前面が開口する収納室を備えた貯蔵庫本体と、庫内空気を冷却ないし加熱する運転機構部と、収納室を開閉する扉などで貯蔵庫を構成している。庫内に収容されるカートは、基台と、基台に立設される一対の支柱と、各支柱の間に形成される多段状の棚などで構成されており、各棚に食品が盛り付けられたトレイを載置することができる。カートを貯蔵庫に収容した状態では、棚部分が収納室に収容され、基台は収納室の底壁と床面との間の空間に収まっている。この状態で扉を閉止することにより、収納室を閉止して食品の冷却処理や加熱処理を行うことができる。カートを貯蔵庫本体に収容した状態において、支柱の基台側の基端部分が接当干渉するのを防ぐために、収納室の底壁の前縁には先の基端部分を受入れる切欠が形成されている。 In this type of food processing apparatus, it is known, for example, in the storage described in Patent Document 1, that a cart on which a group of food trays is mounted is housed in a refrigerator and the entire cart is cooled or heat-treated. .. There, the storage is composed of a storage main body having a storage room with an open front, an operation mechanism for cooling or heating the air inside the storage, a door for opening and closing the storage room, and the like. The cart housed in the refrigerator is composed of a base, a pair of columns erected on the base, and a multi-tiered shelf formed between the columns, and food is served on each shelf. The tray can be placed. When the cart is housed in the storage, the shelves are housed in the storage room, and the base is housed in the space between the bottom wall and the floor of the storage room. By closing the door in this state, the storage chamber can be closed to cool or heat the food. When the cart is housed in the storage body, a notch is formed on the front edge of the bottom wall of the storage chamber to receive the tip end portion in order to prevent the base end portion on the base side of the support column from contacting and interfering with each other. ing.

この種の食品加工装置は定期的に収納室内を洗浄装置で洗浄し、収納室の周囲壁に付着した食材の断片や煮汁などを洗い流して、収納室内を衛生的な状態に保持する必要がある。本出願人は、洗浄装置を備えた食品加工装置を先に提案しているが（特許文献２）、この食品加工装置はカートごと出し入れを行う装置ではなく、食品トレイを人手で収納室内の棚に出し入れする。 In this type of food processing equipment, it is necessary to regularly clean the storage room with a washing device to wash away food fragments and broth adhering to the surrounding walls of the storage room to keep the storage room in a hygienic condition. .. The applicant has previously proposed a food processing device equipped with a cleaning device (Patent Document 2), but this food processing device is not a device for loading and unloading the entire cart, but a shelf in the storage room for manually storing the food tray. Put in and out.

遮水構造６４は、収納庫３に設けたヒンジ６６で遮蔽位置と退避位置の間で往復移動可能に支持される遮蔽体６５と、遮蔽体６５と収納庫３の内面壁の間に設けられて、少なくとも遮蔽位置において遮蔽体６５を移動不能に位置保持する位置保持具６７を備えている。遮蔽位置において対向する遮蔽体６５とドア１１の後面壁６３のいずれか一方に止水パッキン７２が設けられている。 The water-impervious structure 64 is provided between a shield 65 that is supported by a hinge 66 provided in the storage 3 so as to be reciprocally movable between the shield position and the retracted position, and between the shield 65 and the inner wall of the storage 3. A position holder 67 is provided to hold the shield 65 immovably at least in the shield position. A waterproof packing 72 is provided on either one of the shielding body 65 and the rear wall 63 of the door 11 facing each other at the shielding position.

収納庫３の底壁３ａの前部に立設した前壁１５に、カート２のフレーム部３６の出し入れを許す切欠１６が凹み形成されている。トレイ収容部３７が収納庫３に収容された状態において、収納庫３からはみ出るフレーム部３６の前部分を受け入れるフレーム収容部３１がドア１１の内面下部に設けられている。遮蔽位置における遮蔽体６５は、切欠１６の上開口および内開口を収納庫３の側から覆っている。 A notch 16 that allows the frame portion 36 of the cart 2 to be taken in and out is formed in a recess in the front wall 15 erected on the front portion of the bottom wall 3a of the storage 3. In a state where the tray accommodating portion 37 is accommodated in the storage storage 3, a frame accommodating portion 31 for receiving the front portion of the frame portion 36 protruding from the storage storage 3 is provided in the lower part of the inner surface of the door 11. The shield 65 at the shield position covers the upper opening and the inner opening of the notch 16 from the side of the storage 3.

遮蔽体６５は、その一側端に設けたヒンジ６６で前後揺動可能に支持されて、遮蔽ばね６８で遮蔽位置へ向かって移動付勢されている構成を採ることができる。 The shield 65 can be supported by a hinge 66 provided at one end thereof so as to be swingable back and forth, and can be moved and urged toward a shield position by a shield spring 68.

遮蔽体６５は、その下端に設けたヒンジ６６で前後傾倒可能に支持されて、遮蔽ばね６８で遮蔽位置へ向かって起立付勢されている構成を採ることができる。 The shield 65 can be supported by a hinge 66 provided at the lower end thereof so as to be tilted back and forth, and can be erected and urged toward the shield position by the shield spring 68.

位置保持具６７は、遮蔽体６５を磁気吸着する磁石を含んで構成する。 The position holder 67 includes a magnet that magnetically attracts the shield 65.

閉じた状態におけるドア１１の後面壁６３は切欠１６の上方に位置している。遮蔽体６５は、ドア１１の後面壁６３と対向する上カバー７０と、切欠１６の上開口および内開口を収納庫３の側から覆う下カバー７１と、上カバー７０の上縁に設けられてドア１１の後面壁６３に密着する止水パッキン７２を備えている。下カバー７１は、収納庫３の底壁３ａに向かって下り傾斜する排水壁７１ａと、ヒンジ６６で支持される垂直の縦壁７１ｂを一体に備えている。下カバー７１の排水壁７１ａが、ドア１１の後面壁６３より前方へ突出する状態で前向きに張り出されている。 The rear wall 63 of the door 11 in the closed state is located above the notch 16. The shield 65 is provided on the upper cover 70 facing the rear wall 63 of the door 11, the lower cover 71 that covers the upper opening and the inner opening of the notch 16 from the side of the storage 3, and the upper edge of the upper cover 70. A waterproof packing 72 that is in close contact with the rear wall 63 of the door 11 is provided. The lower cover 71 integrally includes a drainage wall 71a that inclines downward toward the bottom wall 3a of the storage 3, and a vertical vertical wall 71b supported by the hinge 66. The drainage wall 71a of the lower cover 71 projects forward in a state of projecting forward from the rear wall 63 of the door 11.

遮蔽位置において遮蔽体６５と対向する前壁１５に、遮蔽体６５が遮蔽位置へ切換ったことを検知するセンサー７５が配置されている。遮蔽位置へ切換った遮蔽体６５をセンサー７５が検知した状態においてのみ、洗浄構造５が作動するように構成する。 A sensor 75 for detecting that the shield 65 has switched to the shield position is arranged on the front wall 15 facing the shield 65 at the shield position. The cleaning structure 5 is configured to operate only when the sensor 75 detects the shield body 65 that has been switched to the shield position.

前壁１５の前面の上縁および切欠１６の周縁に沿って封止パッキン１７が配置されている。カート２を装置本体１から分離して、ドア１１を閉じた状態において、封止パッキン１７に密着して切欠１６を前面側から塞ぐシャッター構造４４が、フレーム収容部３１に配置されている。 The sealing packing 17 is arranged along the upper edge of the front surface of the front wall 15 and the peripheral edge of the notch 16. A shutter structure 44 is arranged in the frame accommodating portion 31 so that the cart 2 is separated from the apparatus main body 1 and the door 11 is closed, and the notch 16 is closed from the front side in close contact with the sealing packing 17.

本発明では、洗浄構造５を備えたカート棚式の食品加工装置において、収納庫３の底壁３ａの前部に切欠１６を形成して、トレイ収容部３７が収納庫３に収容された状態において、フレーム部３６の一部を切欠１６内に受入れるようにした。そのうえで、切欠１６を内面側から覆って、洗浄水が切欠１６へ流下するのを防止する遮水構造６４を、閉じたドア１１と収納庫３の底壁３ａの前部の間に設けた。このように、遮水構造６４が設けられていると、収納庫３の内部を洗浄構造５で洗浄する際に、洗浄水が切欠１６へ浸入するのを、当該遮水構造６４で遮断し止水できるので、洗浄水が切欠１６から床面Ｆへ流下して、床面Ｆが洗浄水で汚損されるのを解消でき、常に衛生的な状態で収納庫３内の洗浄を行うことが可能となる。 In the present invention, in the cart shelf type food processing apparatus provided with the cleaning structure 5, a notch 16 is formed in the front portion of the bottom wall 3a of the storage 3, and the tray storage portion 37 is housed in the storage 3. In the above, a part of the frame portion 36 is received in the notch 16. Then, a water-impervious structure 64 that covers the notch 16 from the inner surface side and prevents the washing water from flowing down to the notch 16 is provided between the closed door 11 and the front portion of the bottom wall 3a of the storage 3. When the impermeable structure 64 is provided in this way, when the inside of the storage 3 is cleaned by the cleaning structure 5, the impermeable structure 64 blocks and stops the infiltration of the cleaning water into the notch 16. Since water can be generated, it is possible to prevent the washing water from flowing down from the notch 16 to the floor surface F and contaminating the floor surface F with the washing water, and it is possible to always wash the inside of the storage 3 in a hygienic state. It becomes.

遮水構造６４は、遮蔽体６５と、遮蔽体６５を遮蔽位置と退避位置の間で往復移動可能に支持するヒンジ６６と、少なくとも遮蔽位置において遮蔽体６５を移動不能に位置保持する位置保持具６７と、例えば遮蔽体６５に設けた止水パッキン７２を備えるものとすることができる。こうした遮水構造６４によれば、冷却処理や洗浄作業を行う際には、作業者が遮蔽体６５を位置保持具６７から分離してヒンジ６６の周りに移動操作するだけで、遮蔽体６５を遮蔽位置と退避位置に適確に位置切換えすることができる。また、遮蔽位置においては、例えば遮蔽体６５に設けた止水パッキン７２がドア１１の後面壁６３に密着するので、ドア１１の後面壁６３に沿って流下する洗浄水が切欠１６に浸入するのを確実に防止できる。止水パッキン７２がドア１１の後面壁６３に設けられている場合にも、同様の作用効果を発揮できる。 The water-impervious structure 64 includes a shield 65, a hinge 66 that reciprocally supports the shield 65 between the shield position and the retracted position, and a position holder that holds the shield 65 immovably at least in the shield position. 67 and, for example, the waterproof packing 72 provided on the shield 65 may be provided. According to such a water-impervious structure 64, when performing cooling treatment or cleaning work, the operator simply separates the shield 65 from the position holder 67 and moves it around the hinge 66 to move the shield 65. The position can be accurately switched between the shielding position and the retracting position. Further, at the shielding position, for example, the waterproof packing 72 provided on the shielding body 65 is in close contact with the rear wall 63 of the door 11, so that the washing water flowing down along the rear wall 63 of the door 11 enters the notch 16. Can be reliably prevented. The same effect can be exhibited when the waterproof packing 72 is provided on the rear wall 63 of the door 11.

収納庫３の底壁３ａの前部に前壁１５を立設し、前壁１５にカート２のフレーム部３６の出し入れを許す切欠１６を凹み形成する。また、ドア１１の内面下部にフレーム収容部３１を設けて、トレイ収容部３７が収納庫３に収容された状態において、収納庫３からはみ出るフレーム部３６の前部分をフレーム収容部３１内に収容して、カート２の前面をドア１１で覆い隠せるようにする。さらに、遮蔽位置における遮蔽体６５は、切欠１６の上開口および内開口を収納庫３の側から覆うようにする。以上のような構成を採ることにより、ドア１１の内面に沿って流下し、あるいは収納庫３の内方から切欠１６へ向かって飛散する洗浄水を、遮蔽体６５で受け止めて底壁３ａへと流下させることができる。 A front wall 15 is erected on the front portion of the bottom wall 3a of the storage 3, and a notch 16 that allows the frame portion 36 of the cart 2 to be taken in and out is formed in the front wall 15 as a recess. Further, a frame accommodating portion 31 is provided in the lower part of the inner surface of the door 11, and in a state where the tray accommodating portion 37 is accommodated in the storage storage 3, the front portion of the frame portion 36 protruding from the storage storage 3 is accommodated in the frame accommodating portion 31. Then, the front surface of the cart 2 can be covered with the door 11. Further, the shield 65 at the shield position covers the upper opening and the inner opening of the notch 16 from the side of the storage 3. By adopting the above configuration, the cleaning water that flows down along the inner surface of the door 11 or scatters from the inside of the storage 3 toward the notch 16 is received by the shield 65 and becomes the bottom wall 3a. It can be made to flow down.

遮蔽体６５は、その一側端に設けたヒンジ６６で前後揺動可能に支持して、遮蔽ばね６８で遮蔽位置へ向かって移動付勢する。こうした遮水構造６４によれば、単にカート２を装置本体１に対して押し込み操作するだけで、遮蔽体６５を遮蔽ばね６８の付勢力に抗して遮蔽位置から退避位置へ移動操作できるので、作業者が遮蔽体６５を遮蔽位置から退避位置へ移動操作する手間を省くことができる。また、カート２を装置本体１から分離した洗浄作業時はもちろん、予冷運転や予熱運転を行う際にも、切欠１６が遮蔽体６５で覆われるので、切欠１６から冷気漏れや暖気漏れ、あるいは外気流入が生じることを極力防いでエネルギーロスを減少できる。 The shield 65 is supported by a hinge 66 provided at one end thereof so as to be swingable back and forth, and is moved and urged toward the shield position by a shield spring 68. According to such a water-impervious structure 64, the shield 65 can be moved from the shield position to the retracted position against the urging force of the shield spring 68 by simply pushing the cart 2 against the device main body 1. It is possible to save the trouble of the operator moving the shield 65 from the shield position to the retracted position. Further, since the notch 16 is covered with the shield 65 not only during the cleaning work in which the cart 2 is separated from the apparatus main body 1 but also during the precooling operation and the preheating operation, cold air leaks, warm air leaks, or outside air from the notch 16. Energy loss can be reduced by preventing inflow as much as possible.

遮蔽体６５は、その下端に設けたヒンジ６６で前後傾倒可能に支持されて、遮蔽ばね６８で遮蔽位置へ向かって起立付勢する構成を採ることができる。係る遮水構造６４によっても、単にカート２を装置本体１に対して押し込み操作するだけで、遮蔽体６５を遮蔽ばね６８の付勢力に抗して遮蔽位置から退避位置へ移動操作できるので、作業者が遮蔽体６５を遮蔽位置から退避位置へ移動操作する手間を省くことができる。また、洗浄作業時はもちろん予冷運転や予熱運転を行う際にも、切欠１６が遮蔽体６５で覆われるので、切欠１６から冷気漏れや暖気漏れ、あるいは外気流入が生じることを極力防いでエネルギーロスを減少できる。さらに、フレーム部３６と収納庫３の底壁３ａの間の上下隙間を利用して、遮蔽体６５を退避させることができる利点もある。 The shield 65 is supported by a hinge 66 provided at the lower end thereof so as to be tilted back and forth, and can be configured to stand up and urge toward the shield position by the shield spring 68. Even with the water-impervious structure 64, the shield 65 can be moved from the shield position to the retracted position against the urging force of the shield spring 68 by simply pushing the cart 2 against the device main body 1. It is possible to save the trouble of a person moving the shield 65 from the shield position to the retracted position. Further, since the notch 16 is covered with the shield 65 not only during the cleaning work but also during the precooling operation and the preheating operation, energy loss is prevented by preventing cold air leakage, warm air leakage, or outside air inflow from the notch 16 as much as possible. Can be reduced. Further, there is an advantage that the shield 65 can be retracted by utilizing the vertical gap between the frame portion 36 and the bottom wall 3a of the storage 3.

位置保持具６７は、遮蔽体６５を磁気吸着する磁石を含んで構成することができる。こうした遮水構造６４によれば、磁石の磁気吸着作用で遮蔽体６５を遮蔽位置や退避位置に位置保持できるので、例えば位置保持具６７がラッチ構造などの機械的な保持構造で構成されている場合に比べて、位置保持具６７の構造の簡素化と低コスト化を同時に実現できる。 The position holder 67 can be configured to include a magnet that magnetically attracts the shield 65. According to such a water-impervious structure 64, the shield 65 can be held at a shield position or a retracted position by the magnetic attraction action of a magnet. Therefore, for example, the position holder 67 is configured with a mechanical holding structure such as a latch structure. Compared with the case, the structure of the position holder 67 can be simplified and the cost can be reduced at the same time.

遮蔽体６５は、上カバー７０と、切欠１６の上開口および内開口を収納庫３の側から覆う下カバー７１と、上カバー７０の上縁に設けられる止水パッキン７２を備えるものとする。また、下カバー７１は、収納庫３の底壁３ａに向かって下り傾斜する排水壁７１ａと、ヒンジ６６で支持される垂直の縦壁７１ｂを一体に備えるものとし、排水壁７１ａをドア１１の後面壁６３より前方へ突出する状態で前向きに張り出すようにした。こうした遮水構造６４によれば、何らかの異常で洗浄水が止水パッキン７２と後面壁６３の封止面を通過して流下してきたとしても、洗浄水を排水壁７１ａで止水して、その左右両端から収納庫３の底壁３ａへと流下でき、洗浄水が切欠１６に浸入するのをさらに確実に解消できる。従って、閉じた状態におけるドア１１の後面壁６３が切欠１６の上方に位置している場合であっても、洗浄水が切欠１６を介して床面Ｆへ流下するのを解消できる。 The shield 65 includes an upper cover 70, a lower cover 71 that covers the upper opening and the inner opening of the notch 16 from the side of the storage 3, and a waterproof packing 72 provided on the upper edge of the upper cover 70. Further, the lower cover 71 is integrally provided with a drainage wall 71a that inclines downward toward the bottom wall 3a of the storage 3 and a vertical vertical wall 71b supported by the hinge 66, and the drainage wall 71a is a door 11 of the door 11. The rear wall 63 is projected forward so as to project forward. According to such an impermeable structure 64, even if the cleaning water flows down through the sealing surface of the waterproof packing 72 and the rear wall 63 due to some abnormality, the cleaning water is stopped by the drain wall 71a and the cleaning water is stopped. It can flow down from both the left and right ends to the bottom wall 3a of the storage 3, and it is possible to more reliably eliminate the infiltration of the washing water into the notch 16. Therefore, even when the rear wall 63 of the door 11 in the closed state is located above the notch 16, it is possible to eliminate the washing water flowing down to the floor surface F through the notch 16.

遮蔽位置において遮蔽体６５と対向する前壁１５に、遮蔽体６５が遮蔽位置へ切換ったことを検知するセンサー７５を配置する。こうした食品加工装置によれば、遮蔽体６５が遮蔽位置へ切換ったことをセンサー７５が検知した状態においてのみ、洗浄構造５を作動させることができる。従って、遮蔽体６５が退避位置に位置保持された状態のままで洗浄作業が開始されて、洗浄水が切欠１６から床面Ｆへ流出するのを確実に防止できる。 A sensor 75 for detecting that the shield 65 has switched to the shield position is arranged on the front wall 15 facing the shield 65 at the shield position. According to such a food processing apparatus, the cleaning structure 5 can be operated only when the sensor 75 detects that the shielding body 65 has switched to the shielding position. Therefore, it is possible to reliably prevent the cleaning water from flowing out from the notch 16 to the floor surface F by starting the cleaning operation while the shield 65 is held in the retracted position.

前壁１５の前面の上縁および切欠１６の周縁に沿って封止パッキン１７を配置する。また、カート２を装置本体１から分離して、ドア１１を閉じた状態において、封止パッキン１７に密着して切欠１６を前面側から塞ぐシャッター構造４４を、フレーム収容部３１に配置する。こうした食品加工装置によれば、カート２を装置本体１から分離してドア１１を閉じた状態において、シャッター構造４４で切欠１６の前面を閉塞できる。従って、カート２を分離して予冷運転や予熱運転を行う際に、切欠１６から冷気漏れや暖気漏れ、あるいは外気流入が生じることを確実に防いで、エネルギーロスのない食品加工装置を提供できる。 The sealing packing 17 is arranged along the upper edge of the front surface of the front wall 15 and the peripheral edge of the notch 16. Further, in a state where the cart 2 is separated from the apparatus main body 1 and the door 11 is closed, a shutter structure 44 which is in close contact with the sealing packing 17 and closes the notch 16 from the front side is arranged in the frame accommodating portion 31. According to such a food processing apparatus, the front surface of the notch 16 can be closed by the shutter structure 44 in a state where the cart 2 is separated from the apparatus main body 1 and the door 11 is closed. Therefore, when the cart 2 is separated to perform the precooling operation or the preheating operation, it is possible to reliably prevent cold air leakage, warm air leakage, or outside air inflow from the notch 16 and provide a food processing apparatus without energy loss.

図６において洗浄構造５は、収納庫３の内部に洗浄水を噴射するスプリンクラー５１と、水道水を収納庫３内に流下供給する給水口５２と、収納庫３の下方に配置されて洗浄水を貯留する貯水タンク５３と、貯水タンク５３内の洗浄水を、洗浄水送給路５４を介してスプリンクラー５１へ加圧送給する送給ポンプ５５などを備えている。給水口５２は給水弁５６を介して水道管に接続されている。蒸発器６の上方には、蒸発器６および送風ファン７に向かって洗浄水を噴射する噴水ノズル５８が配置されている。また、蒸発器６には洗浄後の乾燥を促すヒーター（図示していない）が設けられている。 In FIG. 6, the cleaning structure 5 is arranged below the storage 3, a sprinkler 51 for injecting cleaning water into the storage 3, a water supply port 52 for flowing tap water into the storage 3, and cleaning water. It is provided with a water storage tank 53 for storing water, and a supply pump 55 for pressurizing and supplying the wash water in the water storage tank 53 to the sprinkler 51 via the wash water supply path 54. The water supply port 52 is connected to the water pipe via the water supply valve 56. Above the evaporator 6, a fountain nozzle 58 that injects wash water toward the evaporator 6 and the blower fan 7 is arranged. Further, the evaporator 6 is provided with a heater (not shown) that promotes drying after washing.

スプリンクラー５１は、洗浄水の噴出反力で垂直軸回りに回転しながら洗浄水を噴射供給する。収納庫３の底部には、収納庫３の内部に噴射された洗浄水、および給水口５２から流下された水道水を貯水タンク５３へ流下させる集水口５９が設けられている。貯水タンク５３には、排水路６０と排水弁６１が設けられている。洗浄作業時には、洗浄工程と、前段すすぎ工程と、後段すすぎ工程と、乾燥工程とを順に行うことができる。 The sprinkler 51 injects and supplies the washing water while rotating around the vertical axis by the ejection reaction force of the washing water. At the bottom of the storage 3, a water collecting port 59 is provided to allow the washing water sprayed into the storage 3 and the tap water flowing down from the water supply port 52 to flow down to the water storage tank 53. The water storage tank 53 is provided with a drainage channel 60 and a drainage valve 61. At the time of cleaning work, the cleaning step, the pre-stage rinsing step, the post-stage rinsing step, and the drying step can be performed in order.

上記の急速冷却庫では、食品に対する冷却処理に先立って予冷運転を行い、冷却庫本体１の収納庫３の内部を所定温度にまで冷却する。予冷運転におけるカート２は、冷却庫本体１から分離されて、収納庫３の開口面が右ドア１１で閉止されており、このときの切欠１６は右ドア１１に設けたシャッター４５で閉塞されている（図１参照）。従って、予冷運転時に庫内の冷気が切欠１６から流出し、あるいは外気が切欠１６から庫内に侵入することを解消して、収納庫３内を効率良く所定温度に冷却することができる。 In the above-mentioned rapid cooling chamber, a precooling operation is performed prior to the cooling treatment of the food, and the inside of the storage chamber 3 of the cooling chamber main body 1 is cooled to a predetermined temperature. The cart 2 in the precooling operation is separated from the cooling cabinet main body 1, and the opening surface of the storage cabinet 3 is closed by the right door 11, and the notch 16 at this time is closed by the shutter 45 provided on the right door 11. (See Fig. 1). Therefore, it is possible to eliminate the fact that the cold air in the refrigerator flows out from the notch 16 or the outside air enters the refrigerator through the notch 16 during the pre-cooling operation, and the inside of the storage 3 can be efficiently cooled to a predetermined temperature.

予冷運転が終了すると、右ドア１１を開いた状態で、一群の食品トレイ４０が搭載されたカート２を収納庫３へ向かって押し込む。このとき、基台部３５がガイド枠１８で移動案内されるので、カート２のトレイ収容部３７を収納庫３内へ適正に押し込むことができる。切欠１６を介して収納庫３に進入したフレーム部３６は、収納庫３の底壁３ａの上方に浮き離れた状態で位置しており、基台部３５は格納空間１３内に位置している。また、フレーム部３６の縦枠部３６ａ側が前壁１５の前側にはみ出た状態で、閉塞板４１が封止パッキン１７に接当している。 When the precooling operation is completed, the cart 2 on which the group of food trays 40 is mounted is pushed toward the storage 3 with the right door 11 open. At this time, since the base portion 35 is moved and guided by the guide frame 18, the tray accommodating portion 37 of the cart 2 can be properly pushed into the storage 3. The frame portion 36 that has entered the storage 3 through the notch 16 is located above the bottom wall 3a of the storage 3 in a floating state, and the base portion 35 is located in the storage space 13. .. Further, the closing plate 41 is in contact with the sealing packing 17 in a state where the vertical frame portion 36a side of the frame portion 36 protrudes to the front side of the front wall 15.

カート２を冷却庫本体１内に収納した状態において、右ドア１１を閉じ操作すると、カート２の閉塞板４１を切欠１６の周縁の封止パッキン１７に圧接させて、切欠１６を閉塞板４１で閉塞することができる。同時に図５に示すように、ドアパッキン２９の下辺直線部が閉塞板４１の前面と封止パッキン１７に密着するので、収納庫３の気密性を確保することができる。また、右ドア１１を閉じ操作することにより、フレーム部３６の縦枠部３６ａ側がフレーム収容部３１に入り込んで、シャッター４５をキックばね４７の付勢力に抗して、図５に示す開姿勢に強制的に変位操作するので、右ドア１１を支障なく閉じることができる。この状態のカート２の前面はドア１１で覆い隠されるので、食品を冷却処理するときの急速冷却庫の外観をすっきりさせることができる。 When the right door 11 is closed while the cart 2 is housed in the cooler body 1, the closing plate 41 of the cart 2 is pressed against the sealing packing 17 on the periphery of the notch 16 and the notch 16 is pressed by the closing plate 41. Can be blocked. At the same time, as shown in FIG. 5, since the straight portion on the lower side of the door packing 29 is in close contact with the front surface of the closing plate 41 and the sealing packing 17, the airtightness of the storage 3 can be ensured. Further, by closing the right door 11, the vertical frame portion 36a side of the frame portion 36 enters the frame accommodating portion 31, and the shutter 45 is brought into the open posture shown in FIG. 5 against the urging force of the kick spring 47. Since the displacement operation is forcibly performed, the right door 11 can be closed without any trouble. Since the front surface of the cart 2 in this state is covered with the door 11, the appearance of the rapid cooler when the food is cooled can be made clear.

右ドア１１を閉じたときの同ドア１１の後面壁６３は、切欠１６の真上に位置している。そのため、収納庫３の内部を洗浄する場合に、右ドア１１の後面壁６３に沿って流下する洗浄水が切欠１６へ流下し、床面Ｆへ流出するおそれがある。こうした洗浄水の流出を確実に防止するために、閉じた右ドア１１と収納庫３の底壁３ａの前部の間に、切欠１６を収納庫３の内面側から覆う遮水構造６４を設けている。図１、図４、図７、図８に示すように遮水構造６４は、切欠１６の上面および後面を庫内側から覆う遮蔽体６５と、遮蔽体６５を遮蔽位置と退避位置の間で前後揺動可能（往復移動可能）に支持するヒンジ６６と、遮蔽体６５を遮蔽位置と退避位置において移動不能に位置保持する位置保持具６７と、遮蔽体６５を遮蔽位置へ向かって移動付勢する遮蔽ばね（付勢ばね）６８を備えている。 The rear wall 63 of the door 11 when the right door 11 is closed is located directly above the notch 16. Therefore, when cleaning the inside of the storage 3, the washing water flowing down along the rear wall 63 of the right door 11 may flow down to the notch 16 and flow out to the floor surface F. In order to reliably prevent such outflow of washing water, a water-impervious structure 64 is provided between the closed right door 11 and the front portion of the bottom wall 3a of the storage 3 to cover the notch 16 from the inner surface side of the storage 3. ing. As shown in FIGS. 1, 4, 7, and 8, the water-impervious structure 64 has a shield 65 that covers the upper surface and the rear surface of the notch 16 from the inside of the refrigerator, and the shield 65 is moved back and forth between the shield position and the retracted position. A hinge 66 that supports swingable (reciprocating movement), a position holder 67 that holds the shield 65 in an immovable position at a shield position and a retracted position, and a shield 65 that moves and urges the shield 65 toward the shield position. A shielding spring (urging spring) 68 is provided.

遮蔽位置における遮蔽体６５は、図１、図４に示すように切欠１６の上開口および内開口を収納庫３の側から覆うので、ドア１１の内面に沿って流下し、あるいは収納庫３の内方から切欠１６へ向かって飛散する洗浄水を、遮蔽体６５で受け止めて底壁３ａへと流下させることができる。カート２を収納庫３内へ押し込み操作する際には、フレーム部３６の後端が遮蔽体６５に接当するので、遮蔽体６５はカート２の進入動作に連動して遮蔽位置から退避位置へ変位操作される。また、カート２のトレイ収容部３７が収納庫３内に完全に収まった状態では、遮蔽体６５は図９に示すようにカート２の侵入領域の右側方へ退避した状態で、位置保持具６７で位置保持される。従って、作業者が遮蔽体６５を遮蔽位置から退避位置へ移動操作する手間を省くことができる。 As shown in FIGS. 1 and 4, the shield 65 at the shield position covers the upper opening and the inner opening of the notch 16 from the side of the storage 3, so that the shield 65 flows down along the inner surface of the door 11 or of the storage 3. The washing water scattered from the inside toward the notch 16 can be received by the shield 65 and flow down to the bottom wall 3a. When the cart 2 is pushed into the storage 3, the rear end of the frame portion 36 comes into contact with the shield 65, so that the shield 65 moves from the shield position to the retract position in conjunction with the approaching operation of the cart 2. The displacement is manipulated. Further, when the tray accommodating portion 37 of the cart 2 is completely housed in the storage 3, the shield 65 is retracted to the right side of the intrusion area of the cart 2 as shown in FIG. 9, and the position holder 67 The position is held by. Therefore, it is possible to save the time and effort for the operator to move the shield 65 from the shield position to the retracted position.

遮蔽体６５は、右ドア１１の内面と対向する上カバー７０と、切欠１６の上開口および内開口を収納庫３の側から覆う下カバー７１と、上カバー７０の上縁に沿って設けられる止水パッキン７２を備えている。上カバー７０は、止水パッキン７２を支持する垂直の上壁７０ａと、収納庫３の底壁３ａに向かって下り傾斜する排水壁７０ｂと、下カバー７１の後面に固定される垂直の下壁７０ｃを一体に備えたステンレス板材製のプレス成形品からなる。下カバー７１は、収納庫３の底壁３ａに向かって下り傾斜する排水壁７１ａと、ヒンジ６６で支持される垂直の縦壁７１ｂと、底壁３ａに向かって下り傾斜する裾壁７１ｃを一体に備えた、磁気吸着が可能なステンレス板材製のプレス成形品からなる。 The shield 65 is provided along the upper cover 70 facing the inner surface of the right door 11, the lower cover 71 that covers the upper opening and the inner opening of the notch 16 from the side of the storage 3, and the upper edge of the upper cover 70. It is provided with a waterproof packing 72. The upper cover 70 includes a vertical upper wall 70a that supports the waterproof packing 72, a drainage wall 70b that inclines downward toward the bottom wall 3a of the storage 3, and a vertical lower wall that is fixed to the rear surface of the lower cover 71. It is made of a press-molded product made of a stainless steel plate material integrally provided with 70c. The lower cover 71 integrates a drainage wall 71a that inclines downward toward the bottom wall 3a of the storage 3, a vertical vertical wall 71b supported by the hinge 66, and a hem wall 71c that inclines downward toward the bottom wall 3a. It is made of a press-molded product made of stainless steel plate that can be magnetically attracted in preparation for.

止水パッキン７２は、断面が中空Ｄ字状に形成してあって、その円弧表面が右ドア１１の内面に密着して、右ドア１１に沿って流下する洗浄水を止水し、その左右両端から収納庫３の底壁３ａへと流下させる。下カバー７１の排水壁７１ａの前縁は、右ドア１１の後面壁６３より前方へ突出する状態で前向きに張り出し形成されている（図１参照）。従って、洗浄水が何らかの異常で止水パッキン７２と後面壁６３の封止面を通過して流下してきたとしても、洗浄水を排水壁７１ａで止水して、その左右両端から収納庫３の底壁３ａへと流下させることができる。さらに、裾壁７１ｃと切欠１６の後縁の間には、小さな隙間が確保してあるので、万が一洗浄水が切欠１６に達したとしても、先の隙間から底壁３ａへと流下させることができる。 The water blocking packing 72 has a hollow D-shaped cross section, and its arc surface is in close contact with the inner surface of the right door 11 to stop the washing water flowing down along the right door 11 and to stop the washing water on the left and right sides thereof. It flows down from both ends to the bottom wall 3a of the storage 3. The front edge of the drainage wall 71a of the lower cover 71 is formed so as to project forward from the rear wall 63 of the right door 11 (see FIG. 1). Therefore, even if the cleaning water flows down through the sealing surface of the waterproof packing 72 and the rear wall 63 due to some abnormality, the cleaning water is stopped by the drain wall 71a and the storage 3 is stored from the left and right ends thereof. It can flow down to the bottom wall 3a. Further, since a small gap is secured between the hem wall 71c and the trailing edge of the notch 16, even if the washing water reaches the notch 16, it can flow down from the gap to the bottom wall 3a. it can.

位置保持具６７は磁石で構成されており、遮蔽体６５の下カバー７１の縦壁７１ｂを遮蔽位置と退避位置において移動不能に位置保持する。そのために、前壁１５のピラー３０側の端部後面と、収納庫３の右内周面の後寄りの２個所に位置保持具６７を配置している。洗浄作業を行う場合には、退避位置に位置保持された遮蔽体６５を位置保持具６７から分離して、遮蔽位置へと戻す必要がある。このときの遮蔽体６５は、位置保持具６７から分離されるのと同時に、遮蔽ばね６８の付勢力を受けて遮蔽位置へ自動的に移動変位し、下カバー７１の縦壁７１ｂが前壁１５側の位置保持具６７で吸着保持されるので、遮蔽体６５を退避位置から遮蔽位置へ移動する手間を省くことができる。また、磁石の磁気吸着作用で遮蔽体６５を遮蔽位置や退避位置に位置保持できるので、例えば位置保持具６７をラッチ構造などの機械的な保持構造で構成してある場合に比べて、位置保持具６７の構造の簡素化と低コスト化を同時に実現できる。 The position holder 67 is composed of a magnet, and holds the vertical wall 71b of the lower cover 71 of the shield 65 in an immovable position at the shield position and the retracted position. For this purpose, the position holders 67 are arranged at two locations, the rear surface of the end portion of the front wall 15 on the pillar 30 side and the rear surface of the right inner peripheral surface of the storage 3. When performing the cleaning work, it is necessary to separate the shield 65 whose position is held at the retracted position from the position holder 67 and return it to the shield position. At this time, the shield 65 is separated from the position holder 67, and at the same time, is automatically moved and displaced to the shield position by receiving the urging force of the shield spring 68, and the vertical wall 71b of the lower cover 71 is the front wall 15. Since it is attracted and held by the position holder 67 on the side, it is possible to save the trouble of moving the shield 65 from the retracted position to the shield position. Further, since the shield 65 can be held at the shield position or the retracted position by the magnetic attraction action of the magnet, the position is held as compared with the case where the position holder 67 is configured with a mechanical holding structure such as a latch structure, for example. The structure of the tool 67 can be simplified and the cost can be reduced at the same time.

上記のように、遮蔽体６５が退避位置に位置保持された状態のままで、洗浄作業を行うと、洗浄水が切欠１６へと流れ落ち、その一部が床面Ｆへ流出するおそれがある。こうしたうっかりミスを解消するために、図８に示すように、遮蔽位置において遮蔽体６５対向する前壁１５に、遮蔽体６５が遮蔽位置へ切換ったことを検知するセンサー７５を配置している。センサー７５は市販されているスイッチ付きマグネットからなり、遮蔽体６５が遮蔽位置へ切換った状態においてオン信号を制御部１０に出力する。制御部１０は、センサー７５からオン信号が出力され、さらに洗浄構造５のスタートボタンがオン操作された状態でのみ、洗浄構造５を起動させる。従って、遮蔽体６５が退避位置に位置保持された状態のままで洗浄構造５が作動するのを確実に防止できる。図８において符号７６は防水カバーである。 If the cleaning operation is performed while the shield 65 is held in the retracted position as described above, the cleaning water may flow down to the notch 16 and a part of the cleaning water may flow out to the floor surface F. In order to eliminate such an inadvertent mistake, as shown in FIG. 8, a sensor 75 for detecting that the shield 65 has switched to the shield position is arranged on the front wall 15 facing the shield 65 at the shield position. .. The sensor 75 is composed of a magnet with a switch on the market, and outputs an ON signal to the control unit 10 in a state where the shield 65 is switched to the shield position. The control unit 10 activates the cleaning structure 5 only when the on signal is output from the sensor 75 and the start button of the cleaning structure 5 is turned on. Therefore, it is possible to reliably prevent the cleaning structure 5 from operating while the shield 65 is held in the retracted position. In FIG. 8, reference numeral 76 is a waterproof cover.

上記のように構成したカート棚式の急速冷却庫によれば、カート２を冷却庫本体１から分離し、右ドア１１を閉じて洗浄作業を行う状態では、切欠１６の上面および後面が遮蔽体６５で覆われ、さらに止水パッキン７２が右ドア１１の後面壁６３に密着する。従って、右ドア１１の後面壁６３に沿って流下する洗浄水が切欠１６に浸入するのを確実に防止して、洗浄水の一部が切欠１６から床面Ｆへ流下して、床面Ｆが洗浄水で汚損されるのを解消でき、常に衛生的な状態で収納庫３内の洗浄を行える。また、洗浄後には、単にカート２を装置本体１に対して押し込み操作するだけで、遮蔽体６５を遮蔽ばね６８の付勢力に抗して遮蔽位置から退避位置へ移動操作できる。さらに、洗浄作業時はもちろん予冷運転を行う際にも、切欠１６がシャッター４５と遮蔽体６５で覆われるので、切欠１６から冷気漏れ、あるいは外気流入が生じることを防いでエネルギーロスを減少できる。 According to the cart shelf type rapid cooling cabinet configured as described above, in a state where the cart 2 is separated from the cooling cabinet main body 1 and the right door 11 is closed for cleaning work, the upper surface and the rear surface of the notch 16 are shields. It is covered with 65, and the waterproof packing 72 is in close contact with the rear wall 63 of the right door 11. Therefore, the washing water flowing down along the rear wall 63 of the right door 11 is surely prevented from entering the notch 16, and a part of the washing water flows down from the notch 16 to the floor surface F, so that the floor surface F Can be eliminated from being contaminated with washing water, and the inside of the storage 3 can be washed in a hygienic state at all times. Further, after cleaning, the shield 65 can be moved from the shield position to the retracted position against the urging force of the shield spring 68 by simply pushing the cart 2 against the device main body 1. Further, since the notch 16 is covered with the shutter 45 and the shield 65 not only during the cleaning work but also during the precooling operation, it is possible to prevent cold air leakage or outside air inflow from the notch 16 and reduce energy loss.

遮蔽体６５をヒンジ６６で遮蔽位置と退避位置の間で往復移動可能に支持し、各位置において遮蔽体６５を位置保持具６７で移動不能に位置保持するので、冷却処理や洗浄作業を行う際には、遮蔽体６５を位置保持具６７から分離してヒンジ６６の周りに移動操作するだけで、遮蔽体６５を遮蔽位置と退避位置に適確に位置切換えすることができる。また、遮蔽位置においては、遮蔽体６５に設けた止水パッキン７２がドア１１の後面壁６３に密着するので、右ドア１１の後面壁６３に沿って流下する洗浄水が切欠１６に浸入するのを確実に防止できる。 The shield 65 is supported by the hinge 66 so as to be reciprocally movable between the shield position and the retracted position, and the shield 65 is held in an immovable position by the position holder 67 at each position. The shield 65 can be accurately switched between the shield position and the retracted position simply by separating the shield 65 from the position holder 67 and moving the shield 65 around the hinge 66. Further, at the shielding position, the waterproof packing 72 provided on the shielding body 65 is in close contact with the rear wall 63 of the door 11, so that the washing water flowing down along the rear wall 63 of the right door 11 enters the notch 16. Can be reliably prevented.

図１０は本発明に係るカート棚式の食品加工装置の遮水構造６４の別の実施例を示している。そこでは、遮蔽体６５をその下端に設けたヒンジ６６で前後傾倒可能に支持して、遮蔽ばね６８で遮蔽位置へ向かって起立付勢するようにした。遮蔽体６５は、その裾壁７１ｃの左右に固定したにヒンジ６６で支持されている。こうした遮水構造６４によれば、単にカート２を装置本体１に対して押し込み操作するだけで、遮蔽体６５を遮蔽ばね６８の付勢力に抗して遮蔽位置から退避位置へ傾動操作できるので、作業者が遮蔽体６５を遮蔽位置から退避位置へ移動操作する手間を省くことができる。また、洗浄作業時はもちろん予冷運転を行う際にも、切欠１６が遮蔽体６５で覆われるので、切欠１６から冷気漏れ、あるいは外気流入が生じることを極力防いでエネルギーロスを減少できる。さらに、フレーム部３６と収納庫３の底壁３ａの間の上下隙間を利用して、遮蔽体６５を退避させることができるので、遮蔽体６５を退避させるためのスペースを別途確保する必要がなく、その分だけ収納庫３の構造を簡素化できる。他は先の実施例と同じであるので、同じ部材に同じ符号を付してその説明を省略する。以下の実施例においても同じとする。 FIG. 10 shows another embodiment of the impermeable structure 64 of the cart shelf type food processing apparatus according to the present invention. There, the shield 65 was supported by a hinge 66 provided at the lower end thereof so as to be tilted back and forth, and the shield spring 68 was used to erect and urge the shield toward the shield position. The shield 65 is fixed to the left and right of the hem wall 71c and is supported by hinges 66. According to such a water-impervious structure 64, the shield 65 can be tilted from the shield position to the retracted position against the urging force of the shield spring 68 by simply pushing the cart 2 against the device main body 1. It is possible to save the trouble of the operator moving the shield 65 from the shield position to the retracted position. Further, since the notch 16 is covered with the shield 65 not only during the cleaning work but also during the precooling operation, it is possible to prevent cold air leakage or outside air inflow from the notch 16 as much as possible and reduce energy loss. Further, since the shield 65 can be retracted by using the vertical gap between the frame portion 36 and the bottom wall 3a of the storage 3, there is no need to separately secure a space for retracting the shield 65. Therefore, the structure of the storage 3 can be simplified accordingly. Since the other parts are the same as those in the previous embodiment, the same members are designated by the same reference numerals and the description thereof will be omitted. The same shall apply in the following examples.

図１１は遮水構造６４のさらに別の実施例を示している。そこでは、収納庫３の底壁３ａの前縁に左右一対の切欠１６を形成して、カート２のトレイ収容部３７が収納庫３に収容された状態において、フレーム部３６の縦枠部３６ａが切欠１６に入り込むようにした。遮蔽体６５は、先の実施例で説明した遮蔽体６５と同様に、その右側端がヒンジ６６で前後揺動可能に支持されて、図示していない遮蔽ばね６８で遮蔽位置へ向かって移動付勢されている。遮蔽位置における遮蔽体６５は、左右一対の切欠１６の上面および後面を覆って、洗浄水が切欠１６へ流下するのを防止している。この実施例から理解できるように、本発明に係る遮水構造６４は、切欠１６が底壁３ａの前縁に形成してある場合にも適用できる。 FIG. 11 shows yet another embodiment of the impermeable structure 64. There, a pair of left and right notches 16 are formed on the front edge of the bottom wall 3a of the storage 3, and the vertical frame portion 36a of the frame portion 36 is in a state where the tray storage portion 37 of the cart 2 is housed in the storage 3. Was made to enter the notch 16. Similar to the shield 65 described in the previous embodiment, the shield 65 has its right end supported by a hinge 66 so as to swing back and forth, and is moved toward the shield position by a shield spring 68 (not shown). It is being pushed. The shielding body 65 at the shielding position covers the upper surface and the rear surface of the pair of left and right notches 16 to prevent the washing water from flowing down into the notches 16. As can be understood from this embodiment, the impermeable structure 64 according to the present invention can also be applied when the notch 16 is formed on the front edge of the bottom wall 3a.

上記の実施例以外に、遮水構造６４は左右一対の遮蔽体６５・６５と、各遮蔽体６５を前後揺動可能に支持するヒンジ６６・６６と、各遮蔽体６５を遮蔽位置へ向かって移動付勢する遮蔽ばね６８・６８などで構成することができる。その場合には、カート２が装置本体１に対して押し込み操作されるとき、遮蔽体６５・６５が遮蔽ばね６８の付勢力に抗して遮蔽位置から退避位置へ観音開き状に移動操作される。シャッター構造４４は省略してあってもよい。遮蔽体６５は、付勢ばね６８で退避位置へ向かって移動付勢してあってもよい。また、止水パッキン７２は、ドア１１の後面壁６３に固定してあってもよい。 In addition to the above embodiment, the water-impervious structure 64 includes a pair of left and right shields 65 and 65, hinges 66 and 66 that support each shield 65 so as to swing back and forth, and each shield 65 toward a shield position. It can be composed of shielding springs 68 and 68 that urge the movement. In that case, when the cart 2 is pushed against the device main body 1, the shields 65 and 65 are moved from the shield position to the retracted position in a double-door manner against the urging force of the shield spring 68. The shutter structure 44 may be omitted. The shield 65 may be moved and urged toward the retracted position by the urging spring 68. Further, the waterproof packing 72 may be fixed to the rear wall 63 of the door 11.

位置保持具６７は、磁石で構成する以外に、ラッチ構造や機械的に係脱する係止構造で構成してあってもよい。位置保持具６７は、遮蔽体６５を遮蔽位置へ向かって移動付勢する遮蔽ばね６８が兼ねることができる。その場合には、前壁１５に設けた位置保持具６７を省略してもよい。センサー７５はスイッチ付きマグネット以外に、近接スイッチ、光電スイッチ、マイクロスイッチ、リードスイッチなどのセンサーを適用できる。下カバー７１が磁気吸着不能なステンレス板材で形成してある場合には、磁石と対応する板面に鉄板製の吸着体を固定しておけばよい。本発明に係る食品加工装置は、実施例で説明した急速冷却庫に限られず、食品に対して加熱処理を行う加熱庫等にも適用できる。 The position holder 67 may have a latch structure or a locking structure that mechanically engages and disengages, in addition to the magnet. The position holder 67 can also serve as a shielding spring 68 that moves and urges the shielding body 65 toward the shielding position. In that case, the position holder 67 provided on the front wall 15 may be omitted. In addition to the magnet with a switch, the sensor 75 can apply a sensor such as a proximity switch, a photoelectric switch, a micro switch, or a reed switch. When the lower cover 71 is made of a stainless steel plate that cannot be magnetically attracted, an iron plate adsorbent may be fixed to the plate surface corresponding to the magnet. The food processing apparatus according to the present invention is not limited to the rapid cooling chamber described in the examples, but can also be applied to a heating chamber or the like that heat-treats food.
