Description

本発明は、急速冷却庫等の冷却庫に関する。 The present invention relates to a refrigerator such as a rapid refrigerator.

従来、急速冷却庫の一例として、特許文献１に記載されたものが知られている。このものは、内部が被冷却物を収納する収納室とされ、かつ同収納室の一側面側に冷却器と冷却ファンとを有する冷却ユニットが配設された冷凍庫本体の下面に機械室が設けられ、同機械室内には、圧縮機、空冷式の凝縮器等からなる冷凍装置が装備されて冷却器と冷媒配管により循環接続された構造になり、冷凍装置と冷却ファンを駆動することにより、冷却器で生成された冷気が収納室に循環供給されて、食品が急速冷却されるようになっている。 Conventionally, what was described in patent document 1 is known as an example of a rapid cooling cabinet. This machine room is provided in the lower surface of the freezer body in which the inside is a storage room for storing the object to be cooled, and a cooling unit having a cooler and a cooling fan is provided on one side of the storage room. The machine room is equipped with a refrigeration system comprising a compressor, an air-cooled condenser, etc., and is connected in a circulating manner by a cooler and a refrigerant pipe. By driving the refrigeration system and the cooling fan, The cold air generated by the cooler is circulated and supplied to the storage chamber so that the food is rapidly cooled.

一方、この種の急速冷却庫では、食材の付着等で庫内が汚れやすいという事情があり、また冷却ユニットに配された冷却器についても、食材から発生したガスが付着して腐食するおそれがあるため、適宜にホース等から水道水を掛けて水洗いされる。そして、洗浄に供した後の排水を処理するために、収納室の底壁における手前側の隅部等の適宜位置に排水孔を開口し、同排水孔に接続されたドレンホースを機械室の天井部を通して背面等から外部に導出した手段が講じられている。 On the other hand, in this type of rapid cooling cabinet, there is a situation that the inside of the cabinet is easily soiled due to adhesion of foodstuffs, etc. Also, the gas generated from the foodstuff may adhere to the cooler arranged in the cooling unit and corrode. For this reason, the water is appropriately washed with tap water from a hose or the like. And in order to treat the drainage after being used for cleaning, drainage holes are opened at appropriate positions such as the front corners of the bottom wall of the storage chamber, and the drain hose connected to the drainage hole is connected to the machine room. Means taken out from the back or the like through the ceiling are taken.

上記のような排水処理手段が講じられている場合、当該急速冷却庫では以下のような問題がある。すなわち急速冷却庫では庫内が−数１０℃に冷却され、その冷熱が機械室に配管されたドレンホースにも伝導されてドレンホースが低温となり、一方、機械室内は冷凍装置（凝縮器）を冷却した後の排熱が流通する等で高温雰囲気にあるために、ドレンホースに結露が生じ、その結露水が機械室内に滴下して、配設された電気部品等に降り懸かるおそれがあった。
本発明は上記のような事情に基づいて完成されたものであって、その目的は、ドレンホースへの結露水が機械室内に滴下することを防止するところにある。 When the waste water treatment means as described above is taken, the rapid refrigerator has the following problems. That is, in the rapid cooling chamber, the interior is cooled to −several tens of degrees Celsius, and the cold heat is also transmitted to the drain hose piped in the machine room, and the drain hose becomes low temperature. Since the exhaust heat after cooling is in a high-temperature atmosphere due to circulation, condensation may occur in the drain hose, and the condensed water may drip into the machine room and fall on the installed electrical parts, etc. .
The present invention has been completed based on the above circumstances, and an object thereof is to prevent the dew condensation water on the drain hose from dripping into the machine room.

本発明は、内部が被冷却物を収納する収納室とされ、かつ同収納室の一側面側に冷却器と冷却ファンとを有する冷却ユニットが配設された冷却庫本体の下面には機械室が設けられ、同機械室内には、圧縮機、空冷式の凝縮器等からなる冷凍装置が装備されて前記冷却器と冷媒配管により循環接続され、前記冷凍装置と前記冷却ファンを駆動することにより、前記冷却器で生成された冷気が前記収納室に循環供給されるとともに、前記冷却器本体の庫内底面には排水孔が開口されて、同排水孔に接続されたドレンホースが前記機械室の天井部を通って外部に導出されている冷却庫において、前記機械室の天井面には、前記ドレンホースを挿通する溝形をなすホースカバーが装着され、かつ前記ホースカバーの両側面には、前記機械室内の流通空気が通ることを許容する開口が形成されているところに特徴を有する。 The present invention provides a machine room on the lower surface of a refrigerator main body in which a cooling chamber having a cooling unit and a cooling fan is disposed on one side of the storage chamber. In the machine room, a refrigeration apparatus comprising a compressor, an air-cooled condenser, and the like is installed, and is circulated and connected by the cooler and a refrigerant pipe, and the refrigeration apparatus and the cooling fan are driven. The cool air generated by the cooler is circulated and supplied to the storage chamber, and a drain hole is opened on the bottom surface of the cooler body, and a drain hose connected to the drain hole is connected to the machine chamber. In the refrigerator led out to the outside through the ceiling of the machine room, a hose cover having a groove shape through which the drain hose is inserted is mounted on the ceiling surface of the machine room, and on both side surfaces of the hose cover , Distribution air in the machine room Characterized in place are open to allow it is formed that passes.

ドレンホースに結露して結露水が滴下しても、ホースカバーの溝底で受けられて機械室内に滴下することが防止される。一方、冷凍装置の運転中は、庫外から取り込まれた冷却用空気が凝縮器に当てられてこれを冷却し、冷却に供したのちの排熱が機械室内を通って外部に排出されるが、仮に同排熱がホースカバーで遮られたとしても、側面の開口を通って良好に流通し、凝縮器が効率良く冷却される。その結果、冷凍装置の冷凍能力は確保される。 Even if condensation is condensed on the drain hose and the condensed water is dripped, it is received at the groove bottom of the hose cover and prevented from dripping into the machine room. On the other hand, during the operation of the refrigeration system, the cooling air taken from the outside is applied to the condenser to cool it, and the exhaust heat after cooling is exhausted outside through the machine room. Even if the exhaust heat is blocked by the hose cover, it can be circulated well through the opening on the side surface, and the condenser is efficiently cooled. As a result, the refrigeration capacity of the refrigeration apparatus is ensured.

また、以下のような構成としてもよい。
（１）前記冷却庫本体が、前面開口でかつ同前面開口に開閉扉が装着された構造であって、同冷却庫本体内には、間口方向の一側に前記収納室が、他側に前記冷却ユニットが設置された設置室が設けられ、前記機械室内には、間口方向における前記設置室が設けられた側と対応する側に、前記冷凍装置が前記空冷式の凝縮器と前記圧縮機とを前後に並べた形態で設置され、かつ前記機械室の前面における前記冷凍装置の前方に対応する領域に外気の吸気口が、同機械室における前記冷凍装置の設置側とは反対側の側面に排熱の排気口が形成されているとともに、前記収納室の底面における前記設置室とは反対側の端縁側でかつ手前側の隅部に最深部が形成されて、同最深部に前記排水孔が形成され、前記排水孔に一端が接続された前記ドレンホースの他端が、前記機械室における前記冷凍装置の設置側とは反対側のスペースの天井部を後方に向けて配管され、前記ドレンホースにおける前記機械室内での配管部分のほぼ全長が、前記ホースカバーに挿通されている。 The following configuration may also be used.
(1) The cooling body has a structure having a front opening and an opening / closing door attached to the front opening, and the storage room is located on one side of the frontage direction on the other side. An installation chamber in which the cooling unit is installed is provided, and in the machine room, the refrigeration apparatus is provided with the air-cooled condenser and the compressor on the side corresponding to the side in which the installation chamber is provided in the frontage direction. And a side surface of the machine room opposite to the installation side of the refrigeration apparatus, where the outside air intake port is located in a region corresponding to the front of the refrigeration apparatus on the front surface of the machine room. And an exhaust port for exhaust heat is formed on the bottom surface of the storage chamber, the deepest portion is formed at the corner on the side opposite to the installation chamber and on the near side, and the drainage is formed at the deepest portion. The drain having a hole and having one end connected to the drain hole The other end of the pipe is piped with the ceiling portion of the space opposite to the installation side of the refrigeration apparatus in the machine room facing rearward, and the substantially total length of the pipe part in the machine room in the drain hose is The hose cover is inserted.

庫内を洗浄水で洗浄した場合、洗浄後の排水は収納室の底面の最深部に流下したのち、排水孔からドレンホースを通って排出される。機械室内においてドレンホースに結露して結露水が滴下しても、ホースカバーの底面で受けられる。冷却運転時には、機械室の前面の吸気口から取り込まれた外気によって凝縮器が冷却され、冷却に供した後の排熱が機械室の側面の排気口から排出され、このとき排熱の一部がホースカバーで遮られる可能性があるが、側面の開口を通って良好に排出される。併せてホースカバーの底面に残った結露水が蒸発される。 When the inside of the cabinet is washed with washing water, the drainage after washing flows down to the deepest part of the bottom surface of the storage chamber and is then discharged from the drainage hole through the drain hose. Even if dew condensation drops on the drain hose in the machine room, it can be received at the bottom of the hose cover. During the cooling operation, the condenser is cooled by the outside air taken in from the intake port on the front of the machine room, and the exhaust heat after cooling is exhausted from the exhaust port on the side of the machine room. Can be blocked by the hose cover, but is well drained through the side openings. At the same time, the condensed water remaining on the bottom surface of the hose cover is evaporated.

（２）前記ホースカバーは、底板の両側縁から側板を立ち上げた溝形に形成され、前記両側板の上縁における長さ方向の両端部には、前記機械室の天井面に取り付けられる取付板が外側に直角曲げされた形態で形成されているとともに、前記両側板の長さ方向の中央部において、前記開口が上縁から所定深さ切り欠かれた形態で形成されている。
ホースカバーが、シンプルな構造でもって、機械室の天井面への簡単な取付機能と、取り付けられた後の排熱の流通機能とを確実に果たすことができる。 (2) The hose cover is formed in a groove shape in which the side plate is raised from both side edges of the bottom plate, and is attached to both ends of the upper edge of the side plates in the length direction on the ceiling surface of the machine room. The plate is formed in a shape bent at right angles to the outside, and the opening is formed in a shape that is cut out by a predetermined depth from the upper edge at the center portion in the length direction of the both side plates.
With a simple structure, the hose cover can reliably perform a simple attachment function to the ceiling surface of the machine room and a distribution function of exhaust heat after being attached.

（３）前記ホースカバーにおける前記ドレンホースの前記排水孔と接続された側の端部を収める側の端面が閉鎖されている。
ドレンホースは排水孔と接続された端部側ほど冷却されやすく、したがって同端部側ほど結露水が滴下しやすいといえるが、ホースカバーにおけるドレンホースの排水孔と接続された側の端部を収めた側の端面は閉鎖されているから、滴下した結露水が同端面から零れることが確実に阻止される。 (3) The end face of the hose cover on the side where the end of the drain hose connected to the drain hole is received is closed.
The drain hose is more likely to be cooled at the end connected to the drain hole, so that the condensed water is more likely to drip toward the end, but the end of the hose cover on the side connected to the drain hole of the drain hose Since the end surface on the storage side is closed, the dripped condensed water is reliably prevented from spilling from the end surface.

本発明によれば、冷凍装置の冷凍能力は確保したままで、ドレンホースへの結露水が機械室内に滴下することを防止できる。 ADVANTAGE OF THE INVENTION According to this invention, it can prevent that the dew condensation water to a drain hose dripping in a machine room, ensuring the freezing capacity of a freezing apparatus.

Therefore, a piping space 50 for a drain hose 58, which will be described later, is provided above the electrical box 49.

続いて、庫内の排水処理部分の構造について説明する。庫内の底面５２は、上記した前面開口部１２の下端面１２Ａよりも下方に凹み形成されており、かつ正面視で右側手前の隅部が最深部５３となるような傾斜面として形成されている。
この底面５２の最深部５３には排水孔体５５が装着されている。同排水孔体５５は、底壁を貫通して、機械室４０内の上記した配管スペース５０の天井面５０Ａにおける手前側の位置から下方に突出するようにして装着されている。
図７に示すように、排水孔体５５の下方突出端には、エルボ５６を介して、ドレンホース５８の一端が接続され、その他端が、配管スペース５０の天井面５０Ａに沿うように背面側に向けて配管され、同配管スペース５０の背面から突出して垂下するようになっている。
なお、排水孔体５５は常には栓をして塞がれており、適宜に栓を外して開放されるようになっている。 Then, the structure of the waste water treatment part in a store | warehouse | chamber is demonstrated. The bottom surface 52 in the chamber is formed to be recessed below the lower end surface 12A of the front opening 12 described above, and is formed as an inclined surface such that the corner on the right front side becomes the deepest portion 53 in front view. Yes.
A drain hole 55 is attached to the deepest portion 53 of the bottom surface 52. The drain hole 55 is mounted so as to penetrate the bottom wall and protrude downward from a position on the near side of the ceiling surface 50A of the piping space 50 in the machine room 40 described above.
As shown in FIG. 7, one end of a drain hose 58 is connected to the downward projecting end of the drain hole 55 via an elbow 56, and the other end is on the back side so as to follow the ceiling surface 50 A of the piping space 50. It is piped toward the pipe and protrudes from the back surface of the pipe space 50 and hangs down.
The drain hole body 55 is always closed with a stopper, and is appropriately opened by removing the stopper.

さて、上記したドレンホース５８は、その配管スペース５０内に配管されたほぼ全長にわたって、ホースカバー６０に挿通されている。
このホースカバー６０は、図６にも示すように、亜鉛メッキ鋼板等の金属板を素材として形成され、底板６１の左右両側縁から側板６２を立ち上げた溝形に形成され、手前の開口には前板６３が張られている。同ホースカバー６０は、機械室４０の奥行よりも少し小さい長さ寸法と、ドレンホース５８の直径の２倍程度の深さ寸法を有している。 Now, the drain hose 58 described above is inserted into the hose cover 60 over almost the entire length of the piping hose 50 piped therein.
As shown in FIG. 6, the hose cover 60 is formed using a metal plate such as a galvanized steel plate as a raw material, is formed in a groove shape in which the side plate 62 is raised from the left and right side edges of the bottom plate 61, and has a front opening. The front plate 63 is stretched. The hose cover 60 has a length that is slightly smaller than the depth of the machine room 40 and a depth that is about twice the diameter of the drain hose 58.

ホースカバー６０における左右の側板６２では、長さ方向の中央部における大部分の領域において、上縁から所定深さ（全深さの２／３程度）切り欠かれた形態で開口６４が形成されている。
より詳細には、各側板６２における開口６４が形成された領域よりも手前側の端部領域の方が、奥側の端部領域よりも２倍以上程度長く取られており、手前側端部６２Ａと奥側端部６２Ｂの上縁には、それぞれ外向きに直角曲げされた取付板６５Ａ，６５Ｂが形成されている。各取付板６５Ａ，６５Ｂには、ねじの挿通孔６６が開口されている。 In the left and right side plates 62 of the hose cover 60, an opening 64 is formed in a form in which a predetermined depth (about 2/3 of the total depth) is cut from the upper edge in most of the region in the central portion in the length direction. ing.
More specifically, the end region on the near side is longer than the end region on the near side than the region where the opening 64 is formed in each side plate 62 by the front end portion. At the upper edges of 62A and the back end 62B, mounting plates 65A and 65B are formed, which are bent outward at right angles. A screw insertion hole 66 is opened in each of the mounting plates 65A and 65B.

上記したホースカバー６０は、排水孔体５５の配設位置の直下位置から背面側に真直に延出した形態で、配管スペース５０の天井面５０Ａに当てられ、手前側の左右の取付板６５Ａ及び奥側の左右の取付板６５Ｂをそれぞれねじ止めすることによって固定されている。
このようにホースカバー６０が取り付けられると、排水孔体５５の下方突出端からこれと接続されたドレンホース５８の一端が、前板６３で塞がれたホースカバー６０の手前側の端部内に収められ、背面側に向けて配管されたドレンホース５８がホースカバー６０内に挿通されたのち、奥側の端面から突出してさらには上記のように配管スペース５０の背面から突出するようになっている。なお、ドレンホース５８の背面突出端は、さらにホースが接続される等で、適宜の排水箇所に導かれている。 The above-described hose cover 60 extends straight from the position directly below the position where the drain hole 55 is disposed to the back side, is applied to the ceiling surface 50A of the piping space 50, and the left and right mounting plates 65A and The left and right mounting plates 65B are fixed by screwing.
When the hose cover 60 is attached in this way, one end of the drain hose 58 connected to the drain hole body 55 from the downward projecting end is in the front end portion of the hose cover 60 closed by the front plate 63. The drain hose 58 accommodated and piped toward the back side is inserted into the hose cover 60 and then protrudes from the end face on the back side and further protrudes from the back side of the piping space 50 as described above. Yes. Note that the rear protruding end of the drain hose 58 is led to an appropriate drainage point by connecting a hose or the like.

続いて、本実施形態の作用を説明する。当該急速冷却庫は、加熱調理後の食品を短時間で冷却することに用いられる。
調理後の食品はトレイＴに入れられ、左右のトレイ受け３８で受けられて最大５段にわたって収納室１５内に収納される。断熱扉１３を閉じたのち急速冷却運転がなされ、すなわち冷凍装置４３（圧縮機４５）と冷却ファン２２とが運転されると、図５の矢線に示すように、収納室１５の空気がファンケース２７のシュラウド２８を通って冷却ユニット２０内に吸引されて冷却器２１を通過する間に冷気が生成され、冷却ユニット２０の背面側に吹き出された冷気が、庫内の左側壁１６Ｂに当たって手前と奥に分かれて同冷却ユニット２０の手前側と奥側の側面に回り込んだのち、収納室１５に送り込まれるといった循環流を生じ、これによりトレイＴに入れられた食品が急速冷却される。 Then, the effect | action of this embodiment is demonstrated. The rapid cooling box is used for cooling food after cooking in a short time.
The cooked food is placed in the tray T, received by the left and right tray receivers 38, and stored in the storage chamber 15 over a maximum of five levels. After the heat insulating door 13 is closed, a rapid cooling operation is performed, that is, when the refrigeration apparatus 43 (compressor 45) and the cooling fan 22 are operated, the air in the storage chamber 15 is moved to the fan as shown by the arrow in FIG. Cold air is sucked into the cooling unit 20 through the shroud 28 of the case 27 and passes through the cooler 21, and the cold air blown out to the back side of the cooling unit 20 hits the left side wall 16 B in the cabinet and is on the near side. Then, it divides into the back and wraps around the front side and the back side of the cooling unit 20 and then flows into the storage chamber 15, thereby rapidly cooling the food in the tray T.

この間、凝縮器４４の後面に配された凝縮器ファン４４Ａが併せて駆動されることにより、機械室４０のフロントパネル４１の吸気口４２から外気が吸い込まれて、凝縮器４４を通過することにより凝縮器４４が冷却され、冷却に供した後の排熱は、機械室４０の背面や左右の側面に設けられた排気口４８を通して外部に排出される。
所定時間が経過したら冷却運転が停止され、断熱扉１３を開いたのちトレイＴが庫外に出される。 During this time, the condenser fan 44A disposed on the rear surface of the condenser 44 is driven together so that outside air is sucked from the air inlet 42 of the front panel 41 of the machine room 40 and passes through the condenser 44. The condenser 44 is cooled, and the exhaust heat after cooling is exhausted to the outside through the exhaust ports 48 provided on the back surface and the left and right side surfaces of the machine room 40.
When the predetermined time has elapsed, the cooling operation is stopped, and after the heat insulating door 13 is opened, the tray T is taken out.

本体１０内を清掃する場合は、ホース等で庫内の壁面に向けて水道水を掛けることで行われる。このとき排水孔体５５は、栓を外して開けられる。また、冷却ユニット２０内を併せて水洗いする場合は、両トレイ受け３８を外して庫外に出したのち、冷却ユニット２０の施錠装置３１を外して、ファンケース２７をヒンジ３０を中心にして奥壁１５Ａに向けて開く。そうすると、冷却器カバー２５内の冷却器２１並びに冷却ファン２２が庫内に開放された状態となるから、直接に水を掛けて洗浄できる。
庫内等を洗浄したのちの排水は、収納室の底面５２の最深部５３に流下し、そこに設けられた排水孔体５５から、機械室４０の配管スペース５０に配管されたドレンホース５８を通り、適宜の排水箇所に排水される。 When cleaning the inside of the main body 10, tap water is applied to the wall surface in the warehouse with a hose or the like. At this time, the drain hole 55 is opened by removing the stopper. When the inside of the cooling unit 20 is washed with water, both tray receivers 38 are removed and taken out of the cabinet, then the locking device 31 of the cooling unit 20 is removed, and the fan case 27 is centered around the hinge 30. Open toward wall 15A. If it does so, since it will be in the state by which the cooler 21 and the cooling fan 22 in the cooler cover 25 were open | released in the store | warehouse | chamber, it can wash | clean by pouring water directly.
The drainage after cleaning the inside of the storage chamber flows down to the deepest portion 53 of the bottom surface 52 of the storage chamber, and the drain hose 58 piped into the piping space 50 of the machine room 40 from the drainage hole 55 provided there. Drain to appropriate drainage points.

ここで急速冷却運転中では、庫内が−数１０℃に冷却され、その冷熱が機械室４０の配管スペース５０に配管されたドレンホース５８にも伝導されてドレンホース５８が低温となり、一方、機械室４０内は冷凍装置４３（凝縮器４４）を冷却した後の排熱が流通する等で高温雰囲気にあるために、ドレンホース５８に結露が生じるおそれがあるが、仮に結露が生じて結露水が滴下しても、同ドレンホース５８はホースカバー６０に挿通されているから、結露水はホースカバー６０の溝底で受けられ、その下方に設置された電装箱４９に向けて滴下することが防止される。また、ドレンホース５８は排水孔体５５と接続された端部側ほど冷却されやすく、したがって同端部側ほど結露水が滴下しやすいといえるが、ホースカバー６０におけるドレンホース５８の排水孔体５５と接続された側の端部を収めた手前側の端面は前板６３で塞がれているから、同端面から結露水が零れることが確実に阻止される。 Here, during the rapid cooling operation, the interior is cooled to −several tens of degrees Celsius, and the cold heat is also transmitted to the drain hose 58 piped in the piping space 50 of the machine room 40, and the drain hose 58 becomes low temperature, Since the exhaust heat after cooling the refrigeration apparatus 43 (condenser 44) is in a high temperature atmosphere in the machine room 40, there is a risk of condensation on the drain hose 58. Even when water is dropped, the drain hose 58 is inserted into the hose cover 60, so that the condensed water is received at the groove bottom of the hose cover 60 and dropped toward the electrical box 49 installed below the drain hose. Is prevented. In addition, the drain hose 58 is more easily cooled toward the end connected to the drain hole 55, and therefore, it can be said that the condensed water is more likely to drip toward the end, but the drain hole 55 of the drain hose 58 in the hose cover 60. The end face on the near side that accommodates the end connected to the front is blocked by the front plate 63, so that it is reliably prevented that the condensed water spills from the end face.

一方、冷凍装置４３の運転中は、庫外から取り込まれた外気が凝縮器４４に当てられてこれを冷却し、冷却に供したのちの排熱が機械室４０内を通って外部に排出されるように作用する。ここで、当該急速冷却庫の配置の関係で、機械室４０の左側面の排気口４８が塞がれると、排熱は機械室４０内を正面視で右側に流れて右側面の排気口４８から排気される比重が高くなる。このとき同排熱は、配管スペース５０にも流れてホースカバー６０で遮られる可能性があるが、ホースカバー６０には両側板６２に開口６４が切り欠き形成されているから、同開口６４を通って排熱は良好に流通し、すなわち凝縮器４４は効率良く冷却される。また、排熱が開口６４を通ることで、ホースカバー６０の溝底に残った結露水の蒸発が促進される。 On the other hand, during the operation of the refrigeration apparatus 43, the outside air taken from the outside of the refrigerator is applied to the condenser 44 to cool it, and the exhaust heat after cooling is exhausted outside through the machine room 40. Acts like Here, if the exhaust port 48 on the left side surface of the machine room 40 is blocked due to the arrangement of the quick cooler, the exhaust heat flows to the right side in the machine room 40 in front view and the exhaust port 48 on the right side surface. The specific gravity exhausted from becomes higher. At this time, the exhaust heat may also flow into the piping space 50 and be blocked by the hose cover 60, but the opening 64 is notched in the side plates 62 in the hose cover 60. The exhaust heat passes through well, i.e. the condenser 44 is cooled efficiently. Further, since the exhaust heat passes through the opening 64, evaporation of the condensed water remaining at the groove bottom of the hose cover 60 is promoted.

以上説明したように本実施形態によれば、機械室４０の配管スペース５０の天井面５０Ａに溝形をなすホースカバー６０を取り付けて、同ホースカバー６０内にドレンホース５８を挿通して配管したから、仮にドレンホース５８に結露が生じて結露水が滴下しても、ホースカバー６０の溝底で受けられ、その下方に設置された電装箱４９に向けて滴下することが防止される。また、ドレンホース５８は排水孔体５５と接続された手前の端部側ほど結露して結露水が滴下しやすいといえるが、ドレンホース５８の手前の端部を収めたホースカバー６０の手前側の端面は前板６３で塞がれているから、同端面から結露水が零れることが確実に阻止される。 As described above, according to the present embodiment, the hose cover 60 having a groove shape is attached to the ceiling surface 50 A of the piping space 50 of the machine room 40, and the drain hose 58 is inserted into the hose cover 60 for piping. Therefore, even if dew condensation occurs on the drain hose 58 and the condensed water drops, the drain hose 58 is received at the groove bottom of the hose cover 60 and is prevented from dripping toward the electrical equipment box 49 installed therebelow. In addition, the drain hose 58 is condensated toward the front end connected to the drain hole body 55, and it can be said that the dew condensation water tends to drip, but the front side of the hose cover 60 that houses the front end of the drain hose 58. Since this end face is closed by the front plate 63, it is reliably prevented that condensed water spills from the end face.

また、冷却運転中は、凝縮器４４が吸引された庫外空気で冷却されて冷却に供したのちの排熱が機械室４０内を通って外部に排出されるように作用し、特に同排熱が機械室４０の右側面の排気口４８から排気される際には、同排熱は配管スペース５０にも流れてホースカバー６０で遮られる可能性があるが、ホースカバー６０には両側板６２に開口６４が切り欠き形成されているから、同開口６４を通って排熱は良好に流通する。そのため凝縮器４４は効率良く冷却され、結果、冷凍装置４３の冷凍能力は確保される。また、排熱が開口６４を通ることで、ホースカバー６０の溝底に残った結露水の蒸発が促進され、電装箱４９へ降り懸かることがより確実に防止される。 Further, during the cooling operation, the condenser 44 is cooled by the sucked outside air and used for cooling, so that the exhaust heat is exhausted to the outside through the inside of the machine room 40. When heat is exhausted from the exhaust port 48 on the right side surface of the machine room 40, the exhaust heat may also flow into the piping space 50 and be blocked by the hose cover 60. Since the opening 64 is notched in 62, the exhaust heat passes through the opening 64 well. Therefore, the condenser 44 is efficiently cooled, and as a result, the refrigeration capacity of the refrigeration apparatus 43 is ensured. Further, since the exhaust heat passes through the opening 64, evaporation of the condensed water remaining at the groove bottom of the hose cover 60 is promoted, and it is more reliably prevented that the condensed heat falls on the electrical equipment box 49.

＜関連技術＞
上記実施形態に例示した急速冷却庫では他にも数々の工夫が凝らされており、以下にそれらについて関連技術として説明する。
（１）関連技術１は、図１に示されたところの、機械室４０の前面の下縁に垂設されたショートサイクル防止板７０に関する。このショートサイクル防止板７０は、冷却運転中において、冷凍装置４３を冷却した後の排熱が機械室４０の背面側から吹き出され、背面の壁等に当たって機械室４０の下面を手前側に流通し、機械室４０のフロントパネル４１の吸気口４２から外気とともに吸い込まれるといったショートサイクルを防止することに機能するものである。
本実施形態の急速冷却庫は、機械室４０の外底面の四隅にねじ込まれた脚１１で設置面Ｘ（図９）上に支持されるが、機械室４０の外底面と設置面Ｘとの間隔は微妙に異なる可能性がある。そのためショートサイクル防止板７０は、高さ調節可能に装着されるようになっている。 <Related technologies>
The quick cooler illustrated in the above embodiment has many other ideas, which will be described below as related technologies.
(1) The related technique 1 relates to the short cycle prevention plate 70 that is suspended from the lower edge of the front surface of the machine room 40 as shown in FIG. In the short cycle prevention plate 70, during the cooling operation, the exhaust heat after cooling the refrigeration apparatus 43 is blown out from the back side of the machine room 40, and hits the back wall or the like to circulate the lower surface of the machine room 40 to the near side. It functions to prevent a short cycle in which air is sucked together with outside air from the air inlet 42 of the front panel 41 of the machine room 40.
The quick cooler of this embodiment is supported on the installation surface X (FIG. 9) by the legs 11 screwed into the four corners of the outer bottom surface of the machine room 40. The spacing can be slightly different. Therefore, the short cycle prevention plate 70 is mounted so that the height can be adjusted.

図８及び図９に示すように、ショートサイクル防止板７０は、フルントパネルに設けられた全吸気口４２の間口寸法よりも大きい長さ寸法を持った溝型に形成されており、その正面板７１の両端部には、縦長のねじ７３の挿通孔７２が形成されている。
ショートサイクル防止板７０は、正面板７１の裏面が、機械室４０の底板４０Ａに載せられた載置台４６の手前の端縁に設けられた把手４６Ａに当てられ、両挿通孔７２に通したねじ７３が把手４６Ａに形成されたねじ孔７４にねじ込まれて固定される。
ここで、ショートサイクル防止板７０は、ねじ７３を仮締めした状態で縦長の挿通孔７２に沿って上下動させることにより高さ調節でき、図９の鎖線に示すように、ショートサイクル防止板７０を設置面Ｘに当たるまで下げて取り付けることにより、ショートサイクルをより確実に防止することができる。 As shown in FIGS. 8 and 9, the short cycle prevention plate 70 is formed in a groove shape having a length dimension that is larger than the opening dimensions of all the intake openings 42 provided in the front panel. At both ends of the face plate 71, insertion holes 72 for vertically long screws 73 are formed.
The short cycle prevention plate 70 is a screw that the rear surface of the front plate 71 is applied to a handle 46A provided on the front edge of the mounting table 46 placed on the bottom plate 40A of the machine room 40 and passed through both insertion holes 72. 73 is screwed into a screw hole 74 formed in the handle 46A and fixed.
Here, the height of the short cycle prevention plate 70 can be adjusted by moving it up and down along the vertically long insertion hole 72 with the screw 73 temporarily tightened. As shown by the chain line in FIG. By lowering and mounting until it hits the installation surface X, a short cycle can be prevented more reliably.

（２）関連技術２は、機械室４０の前面枠の増強構造に関する。図１０に示すように、機械室４０の前面枠を構成する上枠７５は、水平板７６の先端に鈎形に屈曲された屈曲板７７が立ち上がり形成された形状であり、同水平板７６の基端側が本体１０の外底面の前縁に固定されている。
一方、機械室４０に設置された凝縮器４４の上面に張られた天板４４Ｂの前縁が手前側に延出され、同延出端に取付板７８が立ち上がり形成されている。
この取付板７８の上縁部が上枠７５の屈曲板７７における垂直部７７Ａの前面下部に当てられ、例えば両端部がねじ７９で止められて固定されている。なお、上枠の屈曲板７７の水平部７７Ｂには、フロントパネル４１の上縁が引っ掛けられて、ねじで取り付けられるようになっている。 (2) The related technique 2 relates to a structure for reinforcing the front frame of the machine room 40. As shown in FIG. 10, the upper frame 75 constituting the front frame of the machine room 40 has a shape in which a bent plate 77 bent in a bowl shape is raised at the tip of the horizontal plate 76. The base end side is fixed to the front edge of the outer bottom surface of the main body 10.
On the other hand, the front edge of the top plate 44B stretched on the upper surface of the condenser 44 installed in the machine room 40 extends to the near side, and a mounting plate 78 rises at the extended end.
The upper edge of the mounting plate 78 is applied to the lower part of the front surface of the vertical portion 77A of the bent plate 77 of the upper frame 75. For example, both ends are fixed by screws 79. It should be noted that the upper edge of the front panel 41 is hooked on the horizontal portion 77B of the bent plate 77 of the upper frame and is attached with screws.

このように、機械室４０の前面枠の上枠７５における大部分の長さ領域が、機械室４０内に設置された凝縮器４４の天板４４Ｂの突出端縁と固定されているのであるから、例えば前面枠に対して、方形から菱形に変形するようなせん断変形をさせる力が作用した場合にも、同変形を規制可能な増強構造とすることができる。
また、上枠７５に設けられた屈曲板７７の垂直部７７Ａと本体１０の前面下部との間に、樋８０が形成され、例えば庫内を水洗いしている場合等、前面開口部１２の下縁から水が飛び出して来たとしても樋８０で受けられ、機械室４０の前面上縁等から機械室４０内に浸水することが防止される。 As described above, most of the length region of the upper frame 75 of the front frame of the machine room 40 is fixed to the protruding edge of the top plate 44B of the condenser 44 installed in the machine room 40. For example, even when a force that causes a shear deformation that deforms from a square to a rhombus is applied to the front frame, the reinforcing structure that can regulate the deformation can be provided.
Further, a flange 80 is formed between the vertical portion 77A of the bent plate 77 provided on the upper frame 75 and the front lower portion of the main body 10, and the bottom of the front opening 12 is washed, for example, when the inside of the cabinet is washed with water. Even if water jumps out from the edge, it is received by the eaves 80 and is prevented from entering the machine room 40 from the upper front edge of the machine room 40 or the like.

（３）関連技術３は、冷却庫本体１０の背面において、図４に示すように、冷却器２１に出し入れされる冷媒配管８１と、冷凍装置４３から引き出された冷媒配管８２との接続部分を配設する箇所の構造に関する。同図に示すように、冷却庫本体１０の背面壁には、背面視で右端寄りの位置（冷却器２１の奥側に対応する位置）で、かつ下部位置において、縦長の窓孔９０が底面に開口して形成されている。 (3) In Related Technology 3, as shown in FIG. 4, on the back surface of the refrigerator main body 10, a connection portion between the refrigerant pipe 81 that is taken in and out of the cooler 21 and the refrigerant pipe 82 drawn out from the refrigeration apparatus 43 It is related with the structure of the location to arrange | position. As shown in the figure, a vertically long window hole 90 is provided on the back wall of the refrigerator main body 10 at a position closer to the right end in the rear view (a position corresponding to the back side of the cooler 21) and at a lower position. It is formed to open.

一方、窓孔９０を覆うようにして蓋体９１が設けられている。この蓋体９１は、図１１及び図１３に示すように、縦長の背面板９２の下端から下面板９３が前方に向けて直角曲げされ、同下面板９３の左右の側縁には側板９４が立ち上がり形成され、さらに下面板９３の先端から押圧板９５が下向きに直角曲げされている。背面板９２の左右の側縁には、取付板９２Ａが同一面上で張り出し形成され、それぞれ上下両端にねじ９７の挿通孔９６が開口されているとともに、左右の側板９４の上縁には、取付板９４Ａが外方に直角曲げされて形成され、それぞれ奥行の中央部にねじの挿通孔９６が開口されている。そして、背面板９２、下面板９３及び押圧板９５の内面に亘って、厚肉の断熱材９８が貼着されている。 On the other hand, a lid 91 is provided so as to cover the window hole 90. As shown in FIGS. 11 and 13, the lid 91 has a bottom plate 93 bent at a right angle from the lower end of a vertically long back plate 92 toward the front, and side plates 94 are formed on the left and right side edges of the bottom plate 93. Further, the pressing plate 95 is bent at a right angle downward from the tip of the lower surface plate 93. At the left and right side edges of the back plate 92, mounting plates 92A are formed on the same surface, and through holes 96 of screws 97 are opened at both upper and lower ends, respectively, and at the upper edges of the left and right side plates 94, The mounting plate 94A is formed by being bent outward at a right angle, and a screw insertion hole 96 is opened at the center of the depth. A thick heat insulating material 98 is attached across the inner surfaces of the back plate 92, the lower plate 93 and the pressing plate 95.

冷媒配管８１，８２の接続は、以下のようにして行われる。図１２に参照して示すように、冷却器２１側の冷媒配管８１は、冷却器２１の奥面から奥方に突出したのち、接続端８１Ａである突出端が下向きに曲げられている。一方、冷凍装置４３側の冷媒配管８２は、機械室４０の底部側で奥方に延出したのち、上方、奥方及び上方へと三度直角曲げされており、上端が接続端８２Ａとなっている。
冷却器２１を収容した冷却ユニット２０は、既述した正規の取付位置よりも庫内の奥方に押し込み可能となっていて、まず冷却ユニット２０が正規よりも奥方に押し込まれることで、冷媒配管８１の接続端８１Ａ側が、図１２に示すように、背面壁の窓孔９０を通して庫外背面に突出する。一方、冷凍装置４３側の冷媒配管８２も庫外背面に引き出され、それぞれの接続端８１Ａ，８２Ａ同士が溶接により接続される。溶接が完了したら、冷媒配管８１，８２の回りに断熱材８３が巻き付けられる。 The refrigerant pipes 81 and 82 are connected as follows. As shown in FIG. 12, the refrigerant pipe 81 on the cooler 21 side protrudes from the back surface of the cooler 21 to the back, and then the protruding end that is the connection end 81 A is bent downward. On the other hand, the refrigerant pipe 82 on the refrigeration apparatus 43 side extends to the back on the bottom side of the machine room 40 and is then bent three times at right angles to the top, the back, and the top, and the upper end is the connection end 82A. .
The cooling unit 20 in which the cooler 21 is accommodated can be pushed deeper into the cabinet than the regular mounting position described above. First, the cooling unit 20 is pushed deeper than the regular, so that the refrigerant pipe 81 As shown in FIG. 12, the connecting end 81A side protrudes through the window hole 90 in the back wall to the rear outside the box. On the other hand, the refrigerant pipe 82 on the side of the refrigeration apparatus 43 is also drawn out to the rear outside the cabinet, and the connection ends 81A and 82A are connected to each other by welding. When the welding is completed, the heat insulating material 83 is wound around the refrigerant pipes 81 and 82.

そののち冷却ユニット２０は、庫内を手前側に戻されて正規位置に取り付けられ、それに伴い両冷媒配管８１，８２が手前側に引き戻されて、図４及び図１３に示すように、両冷媒配管８１，８２の接続部分である縦向き部分８４が、窓孔９０内に収まる。そののち、図１３の矢線に示すように、蓋体９１が、背面板９２により窓孔９０の背面開口を覆い、かつ下面板９３が冷媒配管８２の手前側の屈曲部８２Ｂを収めつつ窓孔９０の下面開口を覆うようにして当てられ、図３及び図１４に示すように、背面板９２の左右の取付板９２Ａが窓孔９０の背面開口の左右の口縁にねじ止めされ、また左右の側板９４の取付板９４Ａが窓孔９０の下面開口の左右の口縁にねじ止めされて固定される。
このように蓋体９１が被着されると、冷媒配管８１，８２の窓孔９０内等で庫外に露出した部分が断熱材８３で覆われた形態で、窓孔９０が閉鎖される。特に図１４に示すように、本体１０の背面に張り出した部分が形成されないから、当該急速冷却庫を設置する部屋の背面壁にぴったりと当てて設置する場合に有効となる。 After that, the cooling unit 20 is returned to the front side in the cabinet and attached to the normal position, and accordingly, both the refrigerant pipes 81 and 82 are pulled back to the front side. As shown in FIGS. A vertically oriented portion 84 that is a connecting portion of the pipes 81 and 82 is accommodated in the window hole 90. After that, as shown by the arrow in FIG. 13, the cover 91 covers the back opening of the window hole 90 with the back plate 92, and the bottom plate 93 accommodates the bent portion 82 B on the near side of the refrigerant pipe 82. 3 and 14, the left and right mounting plates 92A of the back plate 92 are screwed to the left and right mouth edges of the back opening of the window hole 90, as shown in FIGS. The mounting plates 94A of the left and right side plates 94 are fixed to the left and right mouth edges of the lower surface opening of the window hole 90 by screws.
When the lid body 91 is attached in this way, the window hole 90 is closed in a form in which the portions exposed to the outside of the refrigerant pipes 81 and 82 in the window hole 90 and the like are covered with the heat insulating material 83. In particular, as shown in FIG. 14, the projecting portion is not formed on the back surface of the main body 10, which is effective in the case where the quick cooler is installed in close contact with the back wall of the room in which the quick cooler is installed.

なお、図１３に示すように、両冷媒配管８１，８２が手前側に引き戻されて、縦向き部分８４が窓孔９０内に収まった際に、巻き付けられた断熱材８３が庫外へはみ出す可能性があり、そのまま蓋体９１が被せられると、特に背面板９２の内面の断熱材９８が厚さ方向に圧縮されて、断熱効果が低下することが懸念される。
そのため、当該蓋体９１には押圧板９５が設けられ、縦向き部分８４が窓孔９０内に収まった際に、縦向き部分８４が庫外にはみ出ているときには、押圧板９５が冷媒配管８２における奥側の屈曲部８２Ｃを押し、それに伴い縦向き部分８４を窓孔９０内に若干押し込めるように設定されている。したがって、その後に蓋体９１が被着されると、背面板９２の内面の断熱材９８が圧縮されることなく縦向き部分８４に当てられ、断熱機能を有効に果たすことができる。 In addition, as shown in FIG. 13, when both the refrigerant pipes 81 and 82 are pulled back to the front side and the vertical portion 84 is accommodated in the window hole 90, the wound heat insulating material 83 can protrude outside the chamber. If the cover 91 is directly covered, there is a concern that the heat insulating material 98 on the inner surface of the back plate 92 is compressed in the thickness direction and the heat insulating effect is reduced.
For this reason, the lid 91 is provided with a pressing plate 95, and when the vertical portion 84 fits inside the window hole 90 and the vertical portion 84 protrudes outside the chamber, the pressing plate 95 is connected to the refrigerant pipe 82. It is set so that the bent portion 82C on the back side is pushed, and the vertical portion 84 is slightly pushed into the window hole 90 accordingly. Therefore, when the cover body 91 is subsequently attached, the heat insulating material 98 on the inner surface of the back plate 92 is applied to the vertical portion 84 without being compressed, and the heat insulating function can be effectively achieved.

（４）関連技術４は、電装箱４９を載置台４６上で出し入れ可能に設置する部分の構造に関する。電装箱４９は、機械室４０内における上記したドレンホース５８の配管スペース５０の下方において、言い換えると、載置台４６上における正面視で右側縁寄りの位置において、手前側への出し入れ可能に設置されるようになっている。
以下、図１５ないし図１８に基づいて説明する。載置台４６は、手前側に溝形の把手４６Ａを設けて、機械室４０の底板４０Ａ上に出し入れ可能に設けられ、底板４０Ａの前縁と、把手４６Ａの奥側の側面をねじ１００で止めて定位置に固定されるようになっている。 (4) Related technology 4 relates to the structure of the part where the electrical box 49 is installed on the mounting table 46 so that it can be taken in and out. The electrical box 49 is installed in the machine room 40 below the piping space 50 of the drain hose 58, in other words, at a position close to the right edge when viewed from the front on the mounting table 46, so that it can be put in and out. It has become so.
Hereinafter, a description will be given based on FIGS. 15 to 18. The mounting table 46 is provided with a groove-shaped handle 46A on the front side so that it can be put in and out on the bottom plate 40A of the machine room 40, and the front edge of the bottom plate 40A and the side surface on the back side of the handle 46A are fixed with screws 100. Are fixed in place.

電装箱４９は、載置台４６上において単独で出し入れ可能に設置されようになっている。電装箱４９の下面の前縁寄りの位置には、図１５に示すように、載置台４６における把手４６Ａの奥面に当接可能な取付板１０１が垂下して設けられている。一方、電装箱４９の奥面の下縁には、図１７にも示すように、斜め下方に傾いた差込片１０２が突出形成されているとともに、載置台４６の奥側の所定位置には、図１８に示すように、差込片１０２が差し込み可能な同幅の差込溝１０３が形成されている。 The electrical box 49 is installed on the mounting table 46 so that it can be inserted and removed independently. At a position near the front edge of the lower surface of the electrical box 49, as shown in FIG. 15, a mounting plate 101 that can be brought into contact with the inner surface of the handle 46 A in the mounting table 46 is provided to hang down. On the other hand, as shown in FIG. 17, an insertion piece 102 that is inclined obliquely downward is projected and formed at a predetermined position on the back side of the mounting table 46 at the lower edge of the back surface of the electrical box 49. As shown in FIG. 18, an insertion groove 103 having the same width into which the insertion piece 102 can be inserted is formed.

電装箱４９を取り付ける際には、図１５に示すように、電装箱４９を載置台４６上を滑らせつつ奥側に押し込み、図１６に示すように、取付板１０１が載置台４６の把手４６Ａの奥面に当たったところで押し込みが停止され、このとき奥側の差込片１０２が差込溝１０３に差し込まれる。そののち取付板１０１を、載置台４６の把手４６Ａの奥面とともに底板４０Ａの前縁にねじ１００で共締めすることにより、電装箱４９は載置台４６上の所定位置において、前後左右に移動規制された状態で取り付けられる。
電装箱４９を手前に外す場合は、ねじ１００を緩めて取付板１０１を外したのち、前面の把手４９Ａに指を掛けて手前に引っ張ると、差込片１０２を差込溝１０３から抜き出しつつ、載置台４６上を滑らせて手前に引き出すことができる。
なお、載置台４６を手前に引き出すと、電装箱４９は同載置台４６に載った状態で一緒に手前に引き出される。
電装箱４９の奥側をいわゆる引っ掛け構造として、ねじ止めは手前側のみとしたから、電装箱４９の取付作業、並びに電装箱４９の引き出し作業を簡単に行うことができる。 When attaching the electrical equipment box 49, as shown in FIG. 15, the electrical equipment box 49 is slid on the mounting table 46 and pushed to the back side, and the mounting plate 101 is a handle 46A of the mounting table 46 as shown in FIG. Pushing is stopped when it hits the back surface of the back, and at this time, the back-side insertion piece 102 is inserted into the insertion groove 103. After that, by fastening the mounting plate 101 together with the back surface of the handle 46A of the mounting table 46 to the front edge of the bottom plate 40A with the screw 100, the electrical equipment box 49 is restricted from moving back and forth and left and right at a predetermined position on the mounting table 46. It is attached in the state that was done.
When removing the electrical box 49 in the foreground, loosen the screw 100 and remove the mounting plate 101, and then put the finger on the handle 49A on the front and pull it forward, while pulling out the insertion piece 102 from the insertion groove 103, It can be slid on the mounting table 46 and pulled out.
When the mounting table 46 is pulled out toward the front, the electrical equipment box 49 is pulled out together in a state of being placed on the mounting table 46.
Since the rear side of the electrical box 49 has a so-called hook structure and screwing is performed only on the front side, the mounting operation of the electrical box 49 and the drawing operation of the electrical box 49 can be easily performed.

なお、電装箱４９はドレンホース５８を挿通したホースカバー６０の直下位置に配されるのであるから、ホースカバー６０と電装箱４９の天板とを一体形成するようにしてもよい。部品点数の削減を図ることができる。
その場合、電装箱４９の天板を箱本体に対して簡単に着脱できるようにしておけば、ホースカバー６０と電装箱４９の天板は機械室４０内に残して、電装箱４９の箱本体のみを出し入れする構造とすることができる。 Since the electrical box 49 is disposed immediately below the hose cover 60 through which the drain hose 58 is inserted, the hose cover 60 and the top plate of the electrical box 49 may be integrally formed. The number of parts can be reduced.
In that case, if the top plate of the electrical box 49 can be easily attached to and detached from the box body, the hose cover 60 and the top plate of the electrical box 49 are left in the machine room 40, and the box body of the electrical box 49 is left. It is possible to adopt a structure in which only the material is taken in and out.

（５）関連技術５は、冷却庫本体１０の底面５２における前縁側の隅部の構造に関する。
本体１０は大まかには、前面開口の内装箱が、前面開口でかつ同開口縁に内向きのフランジが形成された外装箱内に間隔を開けて嵌められ、両箱の間に断熱材が発泡充填されることで形成されている。ここで、同本体１０の底面５２は、既述したように、洗浄後の排水等が溜められるように、前面開口部１２の下端面１２Ａよりも下方に凹んだ方形の浅皿状に形成され、特に手前側の両隅部では、拭き掃除等がしやすいように丸みが付されている。 (5) The related technique 5 relates to the structure of the corner on the front edge side in the bottom surface 52 of the refrigerator main body 10.
The main body 10 is roughly fitted with an interior box with a front opening and a front opening and an outer box with an inward flange formed at the opening edge, with a gap between them, and a heat insulating material foams between the two boxes. It is formed by filling. Here, as described above, the bottom surface 52 of the main body 10 is formed in a rectangular shallow dish shape that is recessed downward from the lower end surface 12A of the front opening 12 so that drainage after washing can be collected. In particular, both corners on the front side are rounded so as to facilitate wiping and cleaning.

このような構造を構築するために、図１９に示すように、底面５２を構成する内装底板１１０では、手前側の角部において、内側を１／４円形状とした切欠部１１１が形成され、所定幅の側縁部を残した切欠部１１１の内側の領域をプレス加工して凹み形成させることで、隅部に丸みが付された浅皿形状が形成される。
この内装底板１１０の残った前縁部１１２が、前面開口部１２の下端面１２Ａとなり、同じく残った左右の側縁部１１３の内側の端縁寄りの位置に、内装側板１１４が立てられる。そして、上記した切欠部１１１の下面側を覆うようにして、補助板１１５が内装底板１１０の残った前縁部１１２と側縁部１１３とに亘って当てられて、スポット溶接等で固定される。なお、前面開口部１２における上下左右の表面側の口縁部は、外装箱のフランジ１１７で構成される。 In order to construct such a structure, as shown in FIG. 19, in the interior bottom plate 110 that constitutes the bottom surface 52, a notch portion 111 having a 1/4 circular shape on the inside is formed at the corner on the near side, A shallow dish shape with rounded corners is formed by forming a recess by pressing a region inside the notch 111 that leaves a side edge of a predetermined width.
The remaining front edge 112 of the interior bottom plate 110 serves as the lower end surface 12A of the front opening 12, and the interior side plate 114 is erected at a position near the inner edges of the left and right side edges 113 that remain. Then, the auxiliary plate 115 is applied over the remaining front edge portion 112 and the side edge portion 113 of the interior bottom plate 110 so as to cover the lower surface side of the above-described notch portion 111 and is fixed by spot welding or the like. . Note that the upper, lower, left and right front edge portions of the front opening 12 are formed by the flange 117 of the outer box.

上記により、手前側の隅部に丸みを付した浅皿状の底面５２が形成される。ただし、前面開口部１２の下端面１２Ａの両端部には、段差状に凹んだ切欠部１１１が未だ残る。そのため、上記した切欠部１１１の開口を覆うべく合成樹脂製のキャップ１２０が備えられている。同キャップ１２０は、図２０にも示すように、露出した切欠部１１１よりもやや大きい平面形状をなし、その裏面側に、同切欠部１１１の周縁に沿って嵌められたり覆ったりするリブ１２１が形成されているとともに、上記した補助板１１５に開口された位置決め孔１１６に嵌合される位置決めピン１２２が立てられている。すなわちキャップ１２０は、位置決めピン１２２を位置決め孔１１６に挿入して位置決めしつつ、段差状に凹んだ切欠部１１１を塞いで装着される。 As described above, the shallow dish-shaped bottom surface 52 having a rounded corner on the near side is formed. However, the notches 111 that are recessed in steps are still left at both ends of the lower end surface 12A of the front opening 12. Therefore, a synthetic resin cap 120 is provided to cover the opening of the notch 111 described above. As shown in FIG. 20, the cap 120 has a planar shape that is slightly larger than the exposed notch 111, and a rib 121 that fits or covers the periphery of the notch 111 on the back side thereof. The positioning pins 122 that are formed and are fitted into the positioning holes 116 opened in the auxiliary plate 115 are raised. That is, the cap 120 is mounted by closing the notch 111 that is recessed in a step shape while positioning by inserting the positioning pin 122 into the positioning hole 116.

この例の冷却庫本体１０の底面５２のように、隅部に丸みを付した浅皿状に形成する場合は、従来では大掛かりな製造金型を用いて絞り加工を施していたのであるが、本例では、隅部に丸みを付けるに当たっていわゆる曲げ加工だけで済むから、比較的簡単な金型を準備すれば足り、ひいては製造コストの低減に寄与し得る。 Like the bottom surface 52 of the cooler body 10 of this example, when forming in a shallow dish shape with rounded corners, conventionally, drawing was performed using a large production mold, In this example, only a so-called bending process is required for rounding the corner, so it is sufficient to prepare a relatively simple mold, which can contribute to a reduction in manufacturing cost.

（６）関連技術６は、操作パネル１３０並びにその取付構造に関する。図１において、冷却庫本体１０の上面にはテーブルを兼ねた天板１２５が被着され、同天板１２５の正面板の右端寄りの位置に窓孔１２６が開口されており、操作パネル１３０は、窓孔１２６に臨むようにして、本体１０の前面開口部１２の上縁部に取り付けられている。以下、図２１ないし図２３に基づいて説明する。 (6) Related technology 6 relates to operation panel 130 and its mounting structure. In FIG. 1, a top plate 125 serving as a table is attached to the upper surface of the refrigerator main body 10, and a window hole 126 is opened at a position near the right end of the front plate of the top plate 125. The front opening 12 of the main body 10 is attached to the upper edge portion so as to face the window hole 126. Hereinafter, a description will be given with reference to FIGS.

操作パネル１３０は、横長で後面開口の箱形をなす本体部１３１を備え、本体部１３１の正面には、上側に向かうほど深くなった斜めの凹部１３２が形成され、同凹部１３２の奥面が装着部１３３となって適宜に開口１３４が形成されている。一方、各種スイッチや電気部品を搭載した操作基板１３５を備え、同操作基板１３５は、上記した斜めの装着部１３３の裏面の両端部に突設された取付柱１３６を貫通して、各種スイッチ等を開口１３４に臨ませつつ装着部１３３の裏面に当てられ、しかるのち、断面略コ字形をなす押え板１３７が両取付柱１３６に当てられてねじ１３８で止められ、それに伴い、押え板１３７の上下両縁が操作基板１３５の上下両縁を押し付けて固定する。最後に、前面開口の箱形をなす裏カバー１３９が本体部１３１の後面開口内に緊密に嵌合され、下面板同士がねじ１４０で止められて固定される。なお、装着部１３３の表面には開口１３４を覆うようにして操作ラベル１４１が張られている。
本構造によれば、特に断面略コ字形の押え板１３７を利用して、操作基板１３５を装着部１３３の裏面に固定するようにしたから、操作パネル１３０の組立作業性に優れる。 The operation panel 130 includes a main body 131 that is horizontally long and has a box shape with a rear opening. An oblique concave portion 132 that is deeper toward the upper side is formed on the front surface of the main body portion 131. An opening 134 is appropriately formed as a mounting portion 133. On the other hand, an operation board 135 on which various switches and electrical components are mounted is provided, and the operation board 135 penetrates through the mounting pillars 136 projecting from both end portions of the back surface of the above-described oblique mounting portion 133, and various switches and the like. Is pressed against the back surface of the mounting portion 133 while facing the opening 134. After that, a presser plate 137 having a substantially U-shaped cross section is applied to both mounting pillars 136 and fixed with screws 138. Accordingly, the presser plate 137 The upper and lower edges press and fix the upper and lower edges of the operation board 135. Finally, a back cover 139 having a box shape with a front opening is closely fitted into the rear opening of the main body 131, and the lower plates are fixed with screws 140. An operation label 141 is stretched on the surface of the mounting portion 133 so as to cover the opening 134.
According to this structure, since the operation board 135 is fixed to the back surface of the mounting portion 133 using the presser plate 137 having a substantially U-shaped cross section, the assembly workability of the operation panel 130 is excellent.

次に、操作パネル１３０の取付構造を説明する。本体部１３１の底面には、背面側に延出してなる被取付板１４２が、上記のねじ１４０による共締めによって固定されている。同被取付板１４２の延出端側の所定位置には、ねじ１４４の挿通孔１４３が開口されている。
一方、本体１０の前面開口部１２の上縁部１２Ｂの所定位置には、チャンネル形の取付部材１４５がねじ１４６で固定されている。この取付部材１４５の底板１４７には、上記したねじ１４４が螺合されるねじ孔１４８が形成されている。この取付部材１４５の前面板１４９には、操作パネル１３０の裏カバー１３９が当接されるが、この前面板１４９は、図２２に示すように、鉛直方向に対して上端側が手前側（同図の左側）に角度α（１°程度）だけ傾いた傾斜姿勢を取るように形成されている。 Next, the mounting structure of the operation panel 130 will be described. A mounting plate 142 extending to the back side is fixed to the bottom surface of the main body 131 by co-tightening with the screws 140 described above. An insertion hole 143 of the screw 144 is opened at a predetermined position on the extending end side of the attached plate 142.
On the other hand, a channel-shaped attachment member 145 is fixed with a screw 146 at a predetermined position of the upper edge 12B of the front opening 12 of the main body 10. A screw hole 148 into which the above-described screw 144 is screwed is formed in the bottom plate 147 of the mounting member 145. The front plate 149 of the mounting member 145 is in contact with the back cover 139 of the operation panel 130. As shown in FIG. 22, the front plate 149 has an upper end on the near side with respect to the vertical direction. Are inclined so as to be inclined at an angle α (about 1 °) to the left side of FIG.

操作パネル１３０を取り付けるには、図２２の矢線に示すように、被取付板１４２を取付部材１４５の底板１４７の下面に沿わせながら取付部材１４５に向けて押し込み、裏カバー１３９が前面板１４９に当たったのち、図２３に示すように、同前面板１４９が鉛直姿勢を取るまで押し込むと、挿通孔１４３とねじ孔１４８とが整合するから、挿通孔１４３に通したねじ１４４をねじ孔１４８にねじ込むことで固定する。これにより、操作パネル１３０が取付部材１４５に取り付けられるが、このとき前面板１４９の復元弾力により、操作パネル１３０に対して上端側が前傾する方向の付勢力が付与される。 In order to attach the operation panel 130, as shown by the arrow in FIG. 22, the attached plate 142 is pushed toward the attachment member 145 along the bottom surface of the bottom plate 147 of the attachment member 145, and the back cover 139 is moved to the front plate 149. 23, as shown in FIG. 23, when the front plate 149 is pushed in to take a vertical posture, the insertion hole 143 and the screw hole 148 are aligned, so that the screw 144 passed through the insertion hole 143 is inserted into the screw hole 148. Secure by screwing into. As a result, the operation panel 130 is attached to the attachment member 145. At this time, due to the restoring elasticity of the front plate 149, an urging force in a direction in which the upper end side is inclined forward is applied to the operation panel 130.

操作パネル１３０によって操作する場合は、図２３の矢線に示すように、指を操作ラベル１４１の表面から操作基板１３５に向けて押し付けることで行われ、操作パネル１３０は上端側が後傾する方向の押圧力を受けるが、取付部材１４５から上記と逆方向の付勢力を受けているから、操作パネル１３０を押圧した場合にも操作パネル１３０がぐらつくことが規制される。 When operating with the operation panel 130, as shown by the arrow in FIG. 23, the operation panel 130 is operated by pressing a finger from the surface of the operation label 141 toward the operation board 135. Although it receives a pressing force, since it receives an urging force in the opposite direction from the mounting member 145, the operation panel 130 is restricted from wobbling even when the operation panel 130 is pressed.

（７）関連技術７は、当該急速冷凍庫を輸送する場合に用いる輸送用脚体１５０に関する。図１等に示すように、機械室４０の外底面の四隅には、六角頭部を有するねじ状の脚１１が取り付けられるが、輸送時には別途備えられた輸送用脚体１５０が装着されるようになっている。以下、図２５ないし図２７によって説明する。
輸送用脚体１５０は合成樹脂製であって、図２４，図２５に示すように、環形の基台１５１の内周から、上端部が縮径された段付き状の筒形をなす下面開放の柱部１５２が立ち上がり形成され、同柱部１５２の上面板１５３に、脚１１のねじ棒１１Ａが挿通される挿通孔１５４が開口されている。 (7) The related technique 7 relates to the transport leg 150 used when transporting the quick freezer. As shown in FIG. 1 and the like, screw-like legs 11 having hexagonal heads are attached to the four corners of the outer bottom surface of the machine room 40, but separately provided transportation legs 150 are attached during transportation. It has become. This will be described below with reference to FIGS.
The transport leg 150 is made of a synthetic resin, and as shown in FIGS. 24 and 25, the lower surface is opened from the inner periphery of the ring-shaped base 151 to form a stepped cylindrical shape whose upper end is reduced in diameter. The column portion 152 is formed to rise, and an insertion hole 154 through which the screw rod 11 A of the leg 11 is inserted is opened in the upper surface plate 153 of the column portion 152.

この輸送用脚体１５０は基本的には、図２４に参照して示すように、機械室４０を上下反転姿勢としておいて同機械室４０の底板４０Ａにおけるねじ孔４０Ｂの切られた四隅に当てられ、内部に上記の脚１１を入れて上面板１５３の挿通孔１５４からねじ孔４０Ｂにねじ込むことで固定するようになっている。ただしその場合は、上下逆向きとなった輸送用脚体１５０の狭い底の部分において、工具により脚１１のねじ込み操作をしなければならないため、操作し辛い嫌いがある。 Basically, as shown in FIG. 24, the transport leg 150 is placed against the four corners of the screw hole 40B in the bottom plate 40A of the machine room 40 with the machine room 40 turned upside down. The above-mentioned leg 11 is put inside and fixed by being screwed into the screw hole 40B from the insertion hole 154 of the upper surface plate 153. However, in that case, since it is necessary to screw the leg 11 with a tool in the narrow bottom portion of the transportation leg 150 that is turned upside down, it is difficult to operate.

そこでこの例では、連結用のブラケット１６０が備えられてている。このブラケット１６０は金属板製であって、図２４及び図２６に示すように、平面長方形をなし、その中心に脚１１のねじ棒１１Ａの挿通孔１６１が形成されているとともに、長辺側の側縁に、脚１１の六角頭部１１Ｂの平行二面を挟持する山形をなす側板１６２が立てられている。また、対角の隅部に一対の位置決め孔１６３が形成されている。
一方、輸送用脚体１５０の上面板１５３の裏面には、ブラケット１６０を当てる座面１５５が形成され、同座面１５５からは、上記した位置決め孔１６３に挿入される一対の位置決め爪１５６が、対応した配置で立ち上がり形成されている。 Therefore, in this example, a connecting bracket 160 is provided. The bracket 160 is made of a metal plate, and as shown in FIGS. 24 and 26, has a flat rectangular shape with an insertion hole 161 for the screw rod 11A of the leg 11 formed at the center thereof, and a long side of the bracket 160. On the side edge, a side plate 162 having a mountain shape that sandwiches two parallel surfaces of the hexagonal head 11B of the leg 11 is erected. In addition, a pair of positioning holes 163 are formed at diagonal corners.
On the other hand, a seating surface 155 that contacts the bracket 160 is formed on the back surface of the upper surface plate 153 of the transport leg 150, and a pair of positioning claws 156 inserted into the positioning holes 163 from the seating surface 155, It is formed with a corresponding arrangement.

輸送用脚体１５０を装着するには、図２６に示すように、輸送用脚体１５０を上下反転姿勢とし、まず位置決め孔１６３に位置決め爪１５６を挿入しつつブラケット１６０を座面１５５に当て、続いてブラケット１６０の挿通孔１６１から上面板１５３の挿通孔１５４に亘って脚１１のねじ棒１１Ａを挿通し、六角頭部１１Ｂを両側板１６２で挟みつつブラケット１６０に当てる。これにより、ブラケット１６０が輸送用脚体１５０の上面板１５３の裏面に回り止めされて当てられ、そのブラケット１６０に対して脚１１が回り止めされて嵌められることで、輸送用脚体１５０と脚１１とがブラケット１６０を介して一体回転可能に連結された形態となる。 In order to mount the transport leg 150, as shown in FIG. 26, the transport leg 150 is turned upside down, and the bracket 160 is first applied to the seat surface 155 while the positioning claw 156 is inserted into the positioning hole 163. Subsequently, the screw rod 11A of the leg 11 is inserted from the insertion hole 161 of the bracket 160 to the insertion hole 154 of the upper surface plate 153, and the hexagonal head 11B is applied to the bracket 160 while being sandwiched between the side plates 162. As a result, the bracket 160 is prevented from being rotated against the back surface of the upper surface plate 153 of the transport leg 150, and the leg 11 is prevented from being rotated and fitted to the bracket 160, so that the transport leg 150 and the leg are fixed. 11 are connected via a bracket 160 so as to be integrally rotatable.

このように組み付けられた輸送用脚体１５０は、その上面板１５３から突出した脚１１のねじ棒１１Ａを機械室４０の底板４０Ａのねじ孔４０Ｂに螺合したのち、同輸送用脚体１５０をねじ込み方向に回転させると、脚１１のねじ棒１１Ａがねじ込まれることで、図２４に示すように、輸送用脚体１５０が脚１１によって装着された状態となる。輸送用脚体１５０自身を回すことで装着できるから、装着作業を能率良く行うことができる。
設置現場では、輸送用脚体１５０を逆方向に回して脚１１ともども外し、脚１１を単独で取り出したのち、同脚１１を改めてねじ孔４０Ｂにねじ込んで装着すればよい。 The transport leg 150 assembled in this way is screwed into the screw hole 40B of the bottom plate 40A of the machine room 40 after the screw rod 11A of the leg 11 protruding from the upper surface plate 153 is screwed, and then the transport leg 150 is mounted. When the screw 11 is rotated in the screwing direction, the screw rod 11A of the leg 11 is screwed in, so that the transport leg 150 is attached by the leg 11 as shown in FIG. Since it can be mounted by turning the transportation leg 150 itself, the mounting work can be performed efficiently.
At the installation site, the transport leg 150 is rotated in the opposite direction to remove the leg 11 and the leg 11 is taken out alone, and then the leg 11 is screwed into the screw hole 40B and attached.
