Description

【0001】
【発明の属する技術分野】
本発明は、急速凍結庫等の冷却庫に関する。
【0002】
【従来の技術】
従来、急速凍結庫の一例として、図8に示すものが知られている。このものは、断熱箱体からなる凍結庫本体1内に収納室2が設けられて、その図示右側に仕切カバー3を挟んで冷却器室4が形成され、その中には、冷却器5が中央高さ位置に、その上下両側に庫内ファン6が収容されているとともに、仕切カバー3には、冷却器5の正面に複数の吸込口3Aが、庫内ファン6の正面に吹出口3Bがそれぞれ形成されている。そして冷却運転時には、吸込口3Aを通して吸引された庫内空気が冷却器5を通過する間に熱交換により冷気が生成され、この冷気が庫内ファン6により吹出口3Bから収納室2に吹き出されるといった循環流が生じ、収納室2内に収納された食材等が急速凍結される。
この間、冷却器5に加えて、仕切カバー3における吸込口3Aの形成領域付近の表面にも着霜xが進んで吸込口3Aを塞ぐようになる。そのため、冷却器5に装備された除霜ヒータ7に通電することで適宜に除霜運転が行われ、冷却器5付近とともに、仕切カバー3の表面の霜xが溶かされるようになっている。
【0003】
【発明が解決しようとする課題】
一方、この種の冷却庫では、同図8に示されるように、庫内ファン6からの冷気を整流する等の目的で、吹出口3Bの表面側の口縁に風向き板8を設ける場合がある。その場合、仕切カバー3の表面からの除霜水は、風向き板8の上に溜まった後そこから溢れて庫内底部に滴下するように作用する。そして、除霜運転が終了して冷却運転が再開されると、風向き板8上に溜まった水滴が凍って氷塊となり、また滴下する水滴も凍る現象を呈し、除霜運転と冷却運転とが繰り返されるごとに、同図に実線で示すように、氷塊y1が成長し、またつらら状の氷y2が生成される可能性がある。
【0004】
風向き板8上の氷塊y1が大きく成長すると、収納室2に入れられた食材と接触してその品質を損ねたり、吸込口3Aが塞がれて吸込面積が減少することで、冷却性能の低下を招く。また、つらら状の氷y2が成長すると、吹出口3Bの一部に突出するために、吹出面積が減少し、逆に吹出抵抗が増すことになって、これも冷却性能の低下に繋がり、また冷気の吹出方向も変化して、食材等の均一な冷却が阻害されるおそれもあった。
なお、上記のように風向き板8が無いまでも、仕切カバー3における吸込口3Aの形成領域の下方位置の表面に凹凸等があると、同様に氷塊やつつら状の氷が生成されるおそれがある。
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、仕切カバーの表面に除霜水からの氷塊等ができるのを防止するところにある。
【0005】
【課題を解決するための手段】
上記の目的を達成するための手段として、請求項1の発明は、内部を食材等の収納室とした冷却庫本体の一側壁側には、冷却器と庫内ファンとが収容された冷却器室が仕切カバーを挟んで設けられ、この仕切カバーにおける前記冷却器の正面に吸込口が形成されており、前記吸込口を通して吸引された庫内空気が前記冷却器を通過する間に冷気が生成され、この冷気が庫内ファンにより前記収納室に吹き出されて冷却されるようにした冷却庫において、前記仕切カバーにおける前記吸込口の形成領域の下方には、この形成領域付近の表面からの除霜水を受けて前記仕切カバーの裏側に設けられたドレンパンに案内する除霜水案内板が、前記仕切カバーを貫通して設けられている構成としたところに特徴を有する。
【0006】
請求項2の発明は、請求項1に記載のものにおいて、前記仕切カバーにおける前記冷却器の正面と対応する部分が分離された冷却器カバーとなって、揺動開閉可能に支持されており、この冷却器カバーに前記除霜水案内板が設けられているところに特徴を有する。
請求項3の発明は、請求項1または請求項2に記載のものにおいて、前記除霜水案内板が、前記仕切カバーを切り起こすことで仕切カバーと一体形成されているところに特徴を有する。
請求項4の発明は、請求項1ないし請求項3のいずれかに記載のものにおいて、前記ドレンパンは、前記冷却器等からの除霜水を受けるべく冷却器の下方に配設されたドレンパンで兼用されているところに特徴を有する。
【0007】
【発明の作用及び効果】
<請求項1の発明>
仕切カバーにおける吸込口の形成領域付近の表面に付着した霜が除霜運転で溶かされると、その表面に沿って流下した除霜水が除霜水案内板で受けられたのち、仕切カバーの裏側に導かれてドレンパンに排出される。
除霜運転時に仕切カバーの表面に除霜水が残ることが極力避けられるから、引き続く冷却運転の再開によっても氷塊ができることがなく、ひいては仕切カバーの表面で氷塊等が成長することが未然に防止される。
【0008】
<請求項2の発明>
除霜水案内板による除霜水の案内機能を担保しつつ、必要時には冷却器カバーを単独で開放することができる。冷却器の修理や交換等を行う場合に便利となる。
<請求項3の発明>
部品点数を削減でき、ひいては製造コストの低減を図ることができる。
<請求項4の発明>
仕切カバーの表面からの除霜水を受けるドレンパンを、冷却器付近の除霜水を受けるドレンパンで兼用したから、構造がシンプルにまとまる。
【0009】
【発明の実施の形態】
以下、本発明の実施形態を添付図面に基づいて説明する。
<第1実施形態>
本発明の第1実施形態を図1ないし図6によって説明する。この実施形態では、急速凍結庫に適用した場合を例示している。
図1及び図2において、符号10は、前面開口の縦長の断熱箱体からなる凍結庫本体であって、底面の四隅に設けられた脚11で支持されているとともに、前面開口が中央高さ位置で仕切枠12により仕切られて上下の出入口13が形成されており、各出入口13に断熱扉14が揺動開閉可能に支持されている。
【0010】
本体10内は、図1に示すように、正面から見た左側の2/3強の領域が収納室15に、右側の残りの領域が冷却器室16となっている。
収納室15内の四隅には棚柱18が立てられており、断面L字形をなす一対のレール19が向かい合わせの姿勢において、左右両側でそれぞれ手前と奥の棚柱18の間に同一高さで差し渡されて支持されるようになっている。これらのレール19の対が複数段に配され、対をなす両レール19に、方形の浅皿状をなすトレイ20がその両側縁を載せつつ出し入れされるようなっている。
【0011】
一方、冷却器室16内には、そのほぼ中央高さ位置に冷却器21が配置されるとともに、その上下両側に庫内ファン25が取り付けられている。
冷却器21は、本体10の上面に設けられた機械室22内の冷凍装置23と冷媒配管により循環接続され、周知の冷凍サイクルが構成されている。
上下の庫内ファン25は、それぞれ上下両面の開口されたファンケース26に収められ、収納室15側を向いて配設されている。ファンケース26の表面にはベルマウス27が形成されている。
【0012】
冷却器室16の前面には、仕切枠12を挟んだ上下両側にそれぞれ前面カバー29が張設されている。一方、冷却器室16における収納室15との境となる側面には、右側の前後の棚柱18の間において、冷却器カバー31と上下2枚の庫内ファンカバー32とが張設されている。
冷却器カバー31は、冷却器21の正面(図1の左側)に配されるものであって、その全面よりも一回り小さい領域34において、多数の吸込口35が整列して形成されている。庫内ファンカバー32は、それぞれ上下の庫内ファン25の正面に配されるものであって、その裏面の中央部には、ベルマウス27内に嵌合可能な円筒形をなす吹出口36が形成されている。
【0013】
各カバー31,32は、それぞれその奥縁が奥側の棚柱18にヒンジ37を介して取り付けられ、収納室15の奥面に向けて揺動可能に支持されているとともに、手前側の縁部が手前側の棚柱18にねじ38で止められるようになっている。
また除霜用として、冷却器21の表裏両面にはヒータ40が装着されている。それとともに冷却器21の下方には、除霜水を受けるべくドレンパン42が配設されている。ドレンパン42の底面は、図5に示すように、手前から奥に向けて下り勾配となっており、奥側の位置に排水口43が設けられている。
【0014】
さて、冷却器カバー31には、除霜水の案内板50が設けられている。
まず、冷却器カバー31における吸込口35の形成領域34の下方位置には、形成領域34の横幅にほぼ匹敵する長さを持った細長い角孔状の取入口45が開口されている。また、冷却器カバー31の下縁部には、図6に示すように、裏面側の斜め下方に屈曲されたのち、下向きに屈曲された屈曲板46が形成されている。この屈曲板46の垂下部48が、冷却器カバー31が閉鎖された場合に、ドレンパン42における収納室15側の側面の上縁に密着され、ねじ49により固定可能となっている。
【0015】
案内板50は、上記した取入口45にほぼ匹敵する長さを持った横長の板材が、そのほぼ上半分を収納室15側に向けて鈍角に屈曲した逆く字形断面に形成されている。この案内板50の鉛直部52が、上記した取入口45の下側の口縁における裏面に当てられ、ねじ49Aで止められて固定されており、傾斜部51が、取入口45の下側の口縁から斜め上方を向いて表面側に突出している。
また、冷却器カバー31の表面における取入口45の両側には、補助案内板55が取り付けられている。この補助案内板55はクランク状に曲げ形成されて、その鈎形部56で除霜水を受けることが可能となっている。両補助案内板55は、内側の端部が下がった斜め姿勢で取り付けられ、鈎形部56の内端部が、上記した案内板50における取入口45から突出した傾斜部51の両端に臨んでいる。
【0016】
続いて、本実施形態の作用を説明する。稼働時には、食材を収納したトレイ20を左右のレール19にわたって載せて、収納室15内に収納する。係る状態で、冷凍装置23並びに両庫内ファン25が駆動されると、図1の矢線に示すように、収納室15内の庫内空気が、冷却器カバー31の吸込口35を通って冷却器21に向けて吸引され、冷却器21を通過する間に熱交換により冷気が生成される。この冷気は、上下のファンケース26内に導かれた後、庫内ファンカバー32の吹出口36から収納室15内に向けて吹き出されるといった循環流が生じ、もって収納室15内が冷却されて食材が凍結される。
【0017】
この間に、冷却器21付近や、冷却器カバー31の表面に着霜するため、適宜に除霜運転が行われる。そのときは、冷却器21に装備したヒータ40が通電により発熱し、冷却器21等に付着した霜が融かされ、その除霜水は、ドレンパン42で受けられる。
一方、上記のヒータ40の発熱により冷却器カバー31も加熱されるため、その表面に付着した霜も溶かされる。
例えば、吸込口35の形成領域34の表面の除霜水は、表面を流下したのち、図4ないし図6の矢線で示すように、案内板50の傾斜部51で受けられたのち、その傾斜部51上を流下しつつ取入口45を通って冷却器カバー31の裏面に達し、案内板50の鉛直部52、屈曲板46の傾斜部47を伝って、ドレンパン42内に流入する。この除霜水は、冷却器21等からの除霜水ともども、排水口43から排水ホース(図示せず)を通って庫外に排出される。
また、吸込口35の形成領域34の両側における表面の除霜水は、補助案内板55の鈎形部56で受けられたのち、その傾斜に倣って案内板50の傾斜部51上に導かれ、同様にドレンパン42に導かれる。
所定の除霜運転が終了したら、冷却運転が再開される。
【0018】
また、冷却器21や庫内ファン25等の故障等が発見され、修理や部品交換を行う場合は、トレイ20を庫外に抜き出したのち、カバー31,32を個別に開ける。例えば、冷却器21に関して故障があった場合は、まず冷却器21の位置に配されたレール19、必要に応じて対向した側のレール19を外す。それとともに、冷却器カバー31の揺動端をねじ38を緩めて棚柱18から外し、また、屈曲板46をねじ49を緩めてドレンパン42から外し、ヒンジ37を中心として、冷却器カバー31を収納室15の奥面に向けて揺動させる。これにより、冷却器21の設置位置が収納室15側に開放されるから、収納室15側から修理、部品交換等を行うことができる。部品交換等が終わったら、冷却器カバー31を元位置に揺動して戻し、ねじ38,49で固定する。
【0019】
以上のように本実施形態によれば、除霜運転時に冷却器カバー31の表面に除霜水が残ることが極力避けられるから、引き続く冷却運転の再開によっても氷塊ができることがなく、ひいては冷却器カバー31の表面で氷塊が成長したり、つらら状の氷が出きることが未然に防止される。
冷却器カバー31の表面で氷塊が成長するのが防止されることで、氷塊が収納室15に入れられた食材と接触してその品質を損ねるおそれが無く、また、吸込口35が塞がれることなく所定の吸込面積が確保されるから、所定の冷却性能を発揮することができる。一方、下方に向けてつらら状の氷が成長するのが防止されることで、下側の吹出口36の一部を塞ぐことが無くなり、所定の吹出面積が確保され、また吹出抵抗も余分に受けないから、所定の冷却性能を発揮することに有効であり、また冷気の吹出方向も正規方向に維持できるから、食材等の均一な冷却を図ることができる。
【0020】
<第2実施形態>
図7は、本発明の第2実施形態を示す。
この第2実施形態では、冷却器カバー31の取入口45が、素材である板金をプレス加工して切り起こすことで形成されており、この加工時に切り起こされた部分によって、取入口45の下側の口縁から斜め上方を向いて表面側に突出した案内板50Aが形成されている。
その他の構造並びに作用については、上記第1実施形態と同様である。
この第2実施形態によれば、案内板50Aが冷却器カバー31と一体に形成されているから、部品点数を削減でき、また組み付け工程も減少させることができ、ひいては製造コストの低減を図ることができる。
【0021】
<他の実施形態>
本発明は上記記述及び図面によって説明した実施形態に限定されるものではなく、例えば次のような実施形態も本発明の技術的範囲に含まれ、さらに、下記以外にも要旨を逸脱しない範囲内で種々変更して実施することができる。
(1)冷却器カバーの除霜水を受けるドレンパンは、冷却器用のドレンパンとは別に設けてもよく、そのようなものも本発明の技術的範囲に含まれる。
(2)上記実施形態では、冷却器カバーの下端側での強度を確保すること等を目的として、取入口並びに案内板の長さを吸込口の形成領域の範囲に限り、形成領域の外側の除霜水は補助案内板で受けるようにしたが、取入口並びに案内板を冷却器カバーのほぼ全幅にわたって設けることにより、補助案内板を除去した構造としてもよい。
(3)冷却器カバーと庫内ファンカバーとが一体の仕切カバーとして設けられている形式のものにも、本発明は同様に適用可能である。
(4)本発明は、上記実施形態に例示した急速凍結庫に限らず、収納室の側方に冷却器カバーを介して冷却器室が設けられた形式の冷却庫全般に広く適用することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cooling box such as a quick freezing box.
[0002]
[Prior art]
Conventionally, as an example of a quick freezer, the one shown in FIG. 8 is known. In this apparatus, a storage chamber 2 is provided in a freezer main body 1 formed of a heat insulating box, and a cooler chamber 4 is formed on the right side of the figure with a partition cover 3 interposed therebetween, and a cooler 5 is provided therein. At the center height position, the inside fan 6 is accommodated on the upper and lower sides thereof, and the partition cover 3 has a plurality of suction ports 3A in front of the cooler 5 and outlets 3B in front of the inside fan 6. Are formed respectively. In the cooling operation, cool air is generated by heat exchange while the inside air sucked through the suction port 3A passes through the cooler 5, and this cool air is blown out from the outlet 3B into the storage chamber 2 by the inside fan 6. As a result, a circulating flow is generated, and foodstuffs and the like stored in the storage chamber 2 are rapidly frozen.
During this time, in addition to the cooler 5, the surface of the partition cover 3 near the area where the suction port 3A is formed also advances frost x to block the suction port 3A. Therefore, the defrosting operation is appropriately performed by energizing the defrost heater 7 provided in the cooler 5, and the frost x on the surface of the partition cover 3 is melted together with the vicinity of the cooler 5.

In that case, the defrost water from the surface of the partition cover 3 acts to collect on the wind-facing plate 8 and then overflow from there to drop onto the bottom of the compartment. Then, when the defrosting operation is completed and the cooling operation is restarted, the water droplets accumulated on the wind direction plate 8 freeze to form ice blocks, and the dripping water droplets also freeze, and the defrosting operation and the cooling operation are repeated. Every time, as shown by a solid line in the figure, there is a possibility that the ice block y1 grows and icicle-like ice y2 is generated.
[0004]
When the ice block y1 on the wind direction plate 8 grows larger, the quality of the ice block comes into contact with the foodstuffs stored in the storage chamber 2 and the quality thereof is impaired, or the suction area is reduced by closing the suction port 3A, thereby lowering the cooling performance. Invite. Also, when the icicle-like ice y2 grows, it protrudes into a part of the outlet 3B, so that the blowout area decreases and the blowout resistance increases, which also leads to a decrease in cooling performance. The direction in which the cool air is blown also changes, and there is a possibility that uniform cooling of foods and the like may be hindered.
Even if the wind direction plate 8 is not provided as described above, if there is unevenness on the surface of the partition cover 3 at a position below the formation area of the suction port 3A, there is a possibility that ice blocks and whirl-like ice are similarly generated. is there.
The present invention has been completed based on the above circumstances, and an object of the present invention is to prevent the formation of ice blocks and the like from defrost water on the surface of a partition cover.

As shown in FIG. 6, a bent plate 46 is formed on the lower edge of the cooler cover 31. The bent plate 46 is bent obliquely downward on the back side and then bent downward. The hanging portion 48 of the bent plate 46 is in close contact with the upper edge of the side surface of the drain pan 42 on the storage chamber 15 side when the cooler cover 31 is closed, and can be fixed by screws 49.
[0015]
The guide plate 50 is formed of a horizontally long plate material having a length substantially equal to that of the above-described intake port 45 and having an inverted-V-shaped cross section in which an upper half thereof is bent at an obtuse angle toward the storage chamber 15 side. The vertical portion 52 of the guide plate 50 is applied to the back surface of the lower edge of the above-described inlet 45 and is fixed by being screwed down with the screw 49A. It protrudes obliquely upward from the edge to the surface side.
Auxiliary guide plates 55 are attached to both sides of the inlet 45 on the surface of the cooler cover 31. The auxiliary guide plate 55 is formed to be bent in a crank shape, and the hook-shaped portion 56 can receive defrost water. The two auxiliary guide plates 55 are attached in an oblique posture in which the inner ends are lowered, and the inner ends of the hook-shaped portions 56 face both ends of the inclined portion 51 protruding from the intake port 45 of the guide plate 50 described above. I have.
[0016]
Subsequently, the operation of the present embodiment will be described. At the time of operation, the tray 20 storing the food is placed on the left and right rails 19 and stored in the storage room 15. In this state, when the refrigerating device 23 and both the internal fans 25 are driven, the internal air in the storage chamber 15 passes through the suction port 35 of the cooler cover 31 as shown by the arrow in FIG. 1. The air is sucked toward the cooler 21 and is cooled by heat exchange while passing through the cooler 21. After the cool air is guided into the upper and lower fan cases 26, a circulating flow is generated such that the cool air is blown out from the outlet 36 of the in-compartment fan cover 32 into the storage chamber 15, whereby the storage chamber 15 is cooled. Ingredients are frozen.
[0017]
During this time, defrosting operation is appropriately performed to form frost on the vicinity of the cooler 21 and on the surface of the cooler cover 31. At that time, the heater 40 provided in the cooler 21 generates heat by energization, the frost attached to the cooler 21 and the like is melted, and the defrost water is received by the drain pan 42.
On the other hand, since the cooler cover 31 is also heated by the heat generated by the heater 40, the frost adhering to its surface is melted.
For example, the defrost water on the surface of the formation region 34 of the suction port 35 flows down the surface, and is received by the inclined portion 51 of the guide plate 50, as shown by arrows in FIGS. While flowing down on the inclined portion 51, it reaches the back surface of the cooler cover 31 through the inlet 45, flows along the vertical portion 52 of the guide plate 50 and the inclined portion 47 of the bent plate 46, and flows into the drain pan 42. The defrost water is discharged from the refrigerator through the drain port 43 through a drain hose (not shown) together with the defrost water from the cooler 21 and the like.
Further, the defrost water on the surface on both sides of the formation region 34 of the suction port 35 is received by the hook-shaped portion 56 of the auxiliary guide plate 55, and then guided on the inclined portion 51 of the guide plate 50 following the inclination thereof. , And similarly to the drain pan 42.
When the predetermined defrosting operation is completed, the cooling operation is restarted.
[0018]
Further, when a failure or the like of the cooler 21 or the fan 25 in the refrigerator or the like is found and the repair or replacement of parts is performed, the trays 20 are pulled out of the refrigerator and the covers 31 and 32 are individually opened. For example, when there is a failure with respect to the cooler 21, the rail 19 disposed at the position of the cooler 21 and, if necessary, the rail 19 on the opposite side are removed. At the same time, the swinging end of the cooler cover 31 is removed from the shelf 18 by loosening the screw 38, and the bent plate 46 is removed from the drain pan 42 by loosening the screw 49, and the cooler cover 31 is centered on the hinge 37. It swings toward the back of the storage room 15. Thus, the installation position of the cooler 21 is opened to the storage room 15 side, so that repair, component replacement, and the like can be performed from the storage room 15 side. After the replacement of parts, the cooler cover 31 is swung back to the original position and fixed with screws 38 and 49.
[0019]
As described above, according to the present embodiment, defrosting water is prevented from remaining on the surface of the cooler cover 31 during the defrosting operation as much as possible. It is possible to prevent ice blocks from growing on the surface of the cover 31 and icicle-like ice from coming out.
By preventing ice blocks from growing on the surface of the cooler cover 31, there is no risk that the ice blocks will come into contact with foodstuffs stored in the storage chamber 15 and impair the quality thereof, and the suction port 35 will be closed. Since a predetermined suction area is ensured without the need, a predetermined cooling performance can be exhibited. On the other hand, by preventing icicle-like ice from growing downward, it does not block a part of the lower outlet port 36, thereby securing a predetermined outlet area and additionally reducing outlet resistance. Since the cooling air is not received, it is effective to exhibit a predetermined cooling performance, and since the blowing direction of the cool air can be maintained in the normal direction, it is possible to uniformly cool the food material and the like.
[0020]
<Second embodiment>
FIG. 7 shows a second embodiment of the present invention.
In the second embodiment, the inlet 45 of the cooler cover 31 is formed by press-cutting and raising a sheet metal as a raw material. A guide plate 50A that projects obliquely upward from the side edge and protrudes toward the front surface side is formed.
Other structures and operations are the same as those in the first embodiment.
According to the second embodiment, since the guide plate 50A is formed integrally with the cooler cover 31, the number of components can be reduced, the number of assembling steps can be reduced, and the manufacturing cost can be reduced. Can be.
