頭記の扉付き冷凍・冷蔵ショーケース(リーチイン形ショーケース)として、前面に扉を備えたケース本体の庫内に上下段に並ぶ商品陳列棚を架設し、冷気循環ダクトを通じて庫内前面に冷気エアカーテンを吹出し形成するとともに、背面側からも庫内前方に向け冷気を吹き出して庫内を保冷するようにしたショーケースが知られており(例えば、特許文献1参照)、その構成を図3に示す。 As a refrigerated / refrigerated showcase with doors (reach-in type showcase), the product display shelves lined up and down are erected in the cabinet of the case body with the door on the front, and cold air is circulated through the cool air circulation duct on the front of the cabinet. A showcase is known in which an air curtain is blown out and cold air is blown out from the back side toward the front of the interior to keep the interior cool (see, for example, Patent Document 1). Shown in
図3において、1は断熱筐体になる前面開放形のケース本体、2はケース本体1の前面に設けた扉(透視扉)、3はケース本体1の外箱と内箱との間に画成した冷気循環ダクト、4は内箱の庫内陳列室5と冷気循環ダクト3との間を仕切る背面パネル、6はケース本体1の底部に配した冷却器、7はファン、8は上下段に並べて庫内に架設した商品陳列棚であり、前記背面パネル4の壁面には、上下各段の陳列棚8に対応して冷気循環ダクト3の途中経路から庫内の陳列室5に向けて冷気を前方に吹き出す冷気吹出穴4aが開口している。この冷気吹出穴4aは、特許文献1にも記載されているように、上下段に並ぶ各段の陳列棚8の下側に開口位置を合わせて左右方向に分散配列したスリット状の角穴である。なお、図中の符号9は庫内照明用の蛍光灯である。 In FIG. 3, 1 is an open front case body that becomes a heat-insulating housing, 2 is a door (transparent door) provided on the front surface of the case body 1, and 3 is a space between the outer box and the inner box of the case body 1. The formed cool air circulation duct 4 is a rear panel for partitioning the inside box storage chamber 5 and the cool air circulation duct 3, 6 is a cooler disposed at the bottom of the case body 1, 7 is a fan, and 8 is an upper and lower stage. Product display shelves that are arranged in the cabinet, and are arranged on the wall surface of the back panel 4 from the halfway path of the cold air circulation duct 3 to the display chamber 5 in the cabinet corresponding to the display shelves 8 of the upper and lower stages. A cold air blowing hole 4a for blowing out cold air forward is opened. As described in Patent Document 1, the cold air blowing holes 4a are slit-shaped square holes that are distributed in the left-right direction with the opening positions aligned below the display shelves 8 of the upper and lower stages. is there. In addition, the code | symbol 9 in a figure is a fluorescent lamp for interior lighting.
上記した冷気循環式ショーケースの保冷動作は周知の通りであり、保冷運転時には図3の矢印で表すように、冷却器6と熱交換した冷気が冷気循環ダクト3を経由してケース本体1の天井部に開口したエアカーテン吹出口3aからか下方の吸込口3bに向け、扉2の内面に沿って庫内前面に冷気エアカーテン気流Aを吹き出し形成する。また、上下段に並ぶ各段の商品陳列棚8に対応して背面パネル4に穿設した冷気吹出穴4aを通じて冷気循環ダクト3の途中経路から庫内に向け冷気流Bを吹き出して陳列棚8に陳列した商品(不図示)を保冷する。 The cold-reserving operation of the above-described cold-air circulation type showcase is well known, and the cold-air exchanged with the cooler 6 passes through the cold-air circulation duct 3 in the case body 1 as shown by the arrows in FIG. A cold air curtain airflow A is blown out from the air curtain outlet 3a opened in the ceiling toward the lower suction port 3b along the inner surface of the door 2 on the front surface of the interior. Further, the cold shelf B is blown out from the midway path of the cold air circulation duct 3 through the cold air blowing holes 4a formed in the back panel 4 corresponding to the commodity display shelves 8 arranged in the upper and lower stages. Keep the goods (not shown) displayed in
ところで、前記した冷気循環式の扉付きショーケース、特に冷凍食品を保冷する冷凍仕様のショーケースでは、保冷運転中に庫内から商品を取り出すために扉2を開け,閉めると外気が庫内に侵入し、この外気侵入が基で内箱の天井面,側壁面,陳列棚8の下面,および陳列棚8に搭載した商品の表面などに霜が着霜する問題がある。 By the way, in the above-described showcase with a cold air circulation type door, in particular, a freezer-type showcase that keeps frozen food cold, the door 2 is opened and closed in order to take out the product from the inside during the cold-keeping operation, and the outside air enters the inside. There is a problem that frost forms on the ceiling surface, the side wall surface, the lower surface of the display shelf 8, the surface of the product mounted on the display shelf 8, and the like due to the intrusion of the outside air.
すなわち、ショーケースの保冷運転状態で扉2(図3参照)を開放すると、図4で示すように陳列室5の下部領域から庫外に向けて庫内の冷気が漏出する一方、庫外からは庫内の上部域に向けて外気が侵入するようになる。この場合に、庫内の上部域に外気が侵入すると、この侵入外気の流れに前記冷気エアカーテン気流A,庫内の背面から前方に吹き出す冷気流B(図3参照)が干渉(衝突)してこの部分に乱流(渦流)が発生し、庫内に侵入した外気の一部は庫内前面域から保冷状態にある陳列室5の奥の方に向けて流れ込むようになる。 That is, when the door 2 (see FIG. 3) is opened in the cool operation state of the showcase, as shown in FIG. 4, the cool air in the cabinet leaks from the lower region of the display chamber 5 to the outside of the cabinet, while from the outside of the cabinet. Will invade outside air toward the upper area of the chamber. In this case, when the outside air enters the upper area in the warehouse, the cold air curtain airflow A and the cold airflow B (see FIG. 3) blown forward from the back of the inside interfere with (impact) the flow of the intruding outside air. A turbulent flow (vortex) is generated in the lever portion, and a part of the outside air that has entered the interior flows from the front area of the interior toward the back of the display room 5 that is in a cold state.
このために、冷凍仕様のショーケースのように庫内温度が0℃以下のマイナス温度に保冷されていると、外気に含まれた湿気(水蒸気)が昇華,凝固し、陳列室5の庫内壁面、陳列棚8の下面,陳列棚8に搭載した商品の表面などに着霜する。なお、ショーケースの扉2を閉じて外気の侵入が無くなると、庫内の背面側から吹き出す冷気流B(図3参照)が着霜した霜層の表面に沿って流れ、これにより霜が昇華蒸発して次第に消滅するようになるが、扉2を頻繁に開け,閉めしたりすると庫内の各部に発生する着霜量が多くなって霜の十分な解消には至らない。特に、図3のように背面パネル4に開口した冷気吹出穴4aを上下段に並ぶ陳列棚8に合わせてその下面側の左右方向に分散開口した従来構造では、背面パネル4の冷気吹出穴4aを通じて庫内前方に吹き出す冷気流Bが陳列棚の下面に沿った領域を流れるため、この冷気流の流れ領域から外れた内箱の側壁面,商品の周面に沿って流れる冷気風量が不足してこの部分に着霜した霜が消滅されずに残存する。 For this reason, when the inside temperature is kept at a minus temperature of 0 ° C. or lower as in a refrigeration specification showcase, moisture (water vapor) contained in the outside air sublimates and solidifies, and the inside of the display room 5 Frost is formed on the wall surface, the lower surface of the display shelf 8, the surface of the product mounted on the display shelf 8, and the like. In addition, when the door 2 of the showcase is closed and no outside air enters, the cold air flow B (see FIG. 3) blown out from the back side in the warehouse flows along the surface of the frosted frost layer, thereby sublimating the frost. Although it gradually evaporates and disappears, if the door 2 is frequently opened and closed, the amount of frost generated at each part in the cabinet increases, and the frost cannot be sufficiently eliminated. In particular, as shown in FIG. 3, in the conventional structure in which the cold air blowing holes 4a opened in the back panel 4 are distributed and opened in the left and right direction on the lower surface side in accordance with the display shelves 8 arranged in the upper and lower stages, the cold air blowing holes 4a in the back panel 4 Since the cold air flow B that blows out forward through the interior flows through the area along the lower surface of the display shelf, the amount of the cold air flowing along the side wall surface of the inner box and the peripheral surface of the product is not sufficient. The frost that has formed on the lever remains without disappearing.
なお、背面パネル4の全面域に多数の冷気吹出穴4aを分散開口してこの冷気吹出穴を通じて庫内前方に吹き出す冷気流Bの風量を多くすることも考えられるが、この方法ではファン7の総送風量のうち冷気循環ダクト3の途中から庫内に向けて分流する風量割合が大きくなった分だけ冷気循環ダクト3の冷気吹出口3aから吸込口3bに向けて庫内前面に吹き出し形成するエアカーテン気流Aの風量が少なくなってエアカーテンの機能が低下するため、扉2を開放した際の外気侵入量が増えて庫内の着霜量が一層増加してしまう。 In addition, it is conceivable that a large number of the cold air blowing holes 4a are dispersed and opened over the entire area of the back panel 4 to increase the air volume of the cold air flow B blown forward through the cold air blowing holes. Out of the total amount of air blown, the amount of air flow diverted from the middle of the cold air circulation duct 3 toward the inside of the chamber is increased by the amount blown from the cold air outlet 3a of the cold air circulation duct 3 toward the suction port 3b. Since the amount of air curtain airflow A is reduced and the function of the air curtain is reduced, the amount of outside air intrusion when the door 2 is opened increases, and the amount of frost formation in the cabinet further increases.
そこで、従来のショーケースでは内箱の庫内側の壁面に防露,防霜ヒータなどを布設して結露,霜付きを防ぐようにしているが、防露,防霜ヒータを使用するとショーケースの消費電力が増加するほか、ヒータの発熱がそのままショーケースの熱負荷となって冷凍機の負担が増えるといった問題がある。 Therefore, in conventional showcases, a dew-proof / frost-proof heater is installed on the inner wall of the inner box to prevent condensation and frost formation. In addition to an increase in power consumption, there is a problem that the heat generated by the heater directly becomes a heat load on the showcase and the burden on the refrigerator increases.
本発明は上記の点に鑑みなされたものであり、庫内の背面パネルに開口した冷気吹出穴の開口パターンを適正に変更することで、防露,防霜ヒータを用いずに外気の侵入に起因して庫内に発生した着霜を効果的に解消できるように改良した冷気循環式の扉付き冷凍・冷蔵ショーケースを提供することを目的とする。 The present invention has been made in view of the above points, and by appropriately changing the opening pattern of the cold air blowing holes opened in the back panel in the warehouse, it is possible to prevent intrusion of outside air without using a dew-proof and frost-proof heater. An object of the present invention is to provide a cold air circulation type refrigerated / refrigerated showcase with an improved door so as to effectively eliminate frosting caused in the interior.
上記目的を達成するために、本発明によれば、前面に扉を備えるとともに底部に冷却器を配したケース本体の庫内に上下段に並ぶ陳列棚を架設し、ケース本体の内箱/外箱間に画成した冷気循環ダクトを通じて庫内に冷気を循環送風して陳列商品を保冷する冷気循環式の扉付き冷凍・冷蔵ショーケースであり、前記冷気循環ダクトを通じて庫内前面に冷気エアカーテンを吹き出すとともに、庫内の背面パネルには上下各段の陳列棚に対応して前記冷気循環ダクトの途中経路から庫内前方に向けて冷気を吹き出す冷気吹出穴を穿設したものにおいて、前記背面パネルには、庫内の下段側に並ぶ陳列棚を除き、上段側に並ぶ陳列棚,および庫内天井の下面側に開口位置を合せて左右方向に配列した第1パターンの冷気吹出穴と、庫内の下段側に並ぶ陳列棚を除き、上段側に並ぶ陳列棚の左右両端のみに開口位置を合せて上下方向に配列した第2パターンの冷気吹出穴を穿設する(請求項1)。 In order to achieve the above object, according to the present invention, display shelves arranged in upper and lower stages are erected in a case body with a door on the front surface and a cooler at the bottom, It is a refrigeration / refrigeration showcase with a cold air circulation type door that keeps the displayed products cold by circulating cold air into the cabinet through a cold air circulation duct defined between the boxes, and a cold air curtain on the front of the cabinet through the cold air circulation duct In the back panel in the chamber, the back panel is provided with a cold air outlet hole corresponding to the upper and lower display shelves to blow out cool air from the midway path of the cool air circulation duct toward the front of the chamber. In the panel, except for the display shelves arranged on the lower side of the cabinet, the display shelves arranged on the upper side, and the cold air outlet holes of the first pattern arranged in the left-right direction with the opening position aligned with the lower surface side of the ceiling in the cabinet, Along the lower side of the chamber Except for shelves, bored cold air blowing ports of the second pattern arranged in the vertical direction only to the left and right ends of the display shelf arranged on the upper side and the combined opening position (claim 1).
上記のように、前面に扉を備えるとともに底部に冷却器を配したケース本体の庫内に上下段に並ぶ陳列棚を架設し、ケース本体の内箱/外箱間に画成した冷気循環ダクトを通じて庫内に冷気を循環送風して陳列商品を保冷する冷気循環式の扉付き冷凍・冷蔵ショーケースであり、前記冷気循環ダクトを通じて庫内前面に冷気エアカーテンを吹き出すとともに、庫内の背面パネルには上下各段の陳列棚に対応して前記冷気循環ダクトの途中経路から庫内前方に向けて冷気を吹き出す冷気吹出穴を穿設したものにおいて、庫内の背面パネルには、庫内の下段側に並ぶ陳列棚を除き、上段側に並ぶ陳列棚,および庫内天井の下面側に開口位置を合せて左右方向に配列した第1パターンの冷気吹出穴と、庫内の下段側に並ぶ陳列棚を除き、上段側に並ぶ陳列棚の左右両端のみに開口位置を合せて上下方向に配列した第2パターンの冷気吹出穴を穿設することにより、相対的に冷気循環ダクトの冷気吹出口(天井側)を通じて庫内前面に吹き出し形成するエアカーテン気流の風量が増え、扉の開放時に庫外から庫内上部域(上段側)に流入する外気の侵入量を抑制して庫内に発生する着霜量を効果的に低減させることができ、ショーケースの保冷運転中には第1,および第2パターンの冷気吹出穴を通じて冷気循環ダクトの途中から庫内前方に向けて吹き出す冷気流が、各段の陳列棚の裏面、内箱の庫内側壁面,天井面、および商品の表面に沿って満遍なく流れるようになる。これにより、保冷運転中における扉の開放に伴い前方から庫内上部域に侵入する外気によって庫内の各部に着霜した霜を効率よく昇華蒸発させてその霜層を満遍なく確実に消滅することかできる。しかも、従来のショーケースのように防露,防霜ヒータを用いないので高い省エネ効果が得られる。 As mentioned above, a cold air circulation duct that is constructed between the inner box / outer box of the case body, with the display shelves arranged in the upper and lower stages in the case body with the door on the front and the cooler at the bottom. Through the cold air circulation duct, the cold air curtain is blown to the front of the interior through the cold circulation duct, and the rear panel of the interior Is provided with a cold air outlet hole that blows out cold air from the midway path of the cold air circulation duct toward the front of the cabinet corresponding to the upper and lower display shelves . Except for the display shelves arranged on the lower side, the display shelves arranged on the upper side, the first pattern cold air holes arranged in the left-right direction with the opening position aligned with the lower surface side of the ceiling in the cabinet, and the lower shelf in the cabinet Except for display shelves, By forming the second pattern of cold air outlet holes that are aligned in the vertical direction with the opening positions aligned only on the left and right ends of the display shelf, it is relatively placed on the front of the cabinet through the cold air outlet (ceiling side) of the cold air circulation duct. The amount of air curtain airflow generated by the blowout increases, and the amount of frost generated inside the cabinet is effectively reduced by suppressing the amount of outside air entering from the outside of the cabinet to the upper area (upper side) when the door is opened. During the cool-down operation of the showcase, the cold air blown out from the middle of the cold air circulation duct through the cold air blowing holes of the first and second patterns toward the front of the interior of the cabinet, It flows evenly along the inner wall surface of the inner box, the ceiling surface, and the surface of the product. By this, it is possible to efficiently sublimate and evaporate the frost that has formed on each part of the interior by the outside air that enters the upper area of the interior from the front as the door opens during the cold insulation operation, and the frost layer disappears evenly and reliably. it can. In addition, unlike the conventional showcase, no dew-proof and frost-proof heater is used, so a high energy saving effect can be obtained.
以下、本発明の実施の形態を図1、および図2に示す実施例に基づいて説明する。なお図示実施例の図中で図3に対応する部位には同じ符号を付してその説明は省略する。 Hereinafter, embodiments of the present invention will be described based on the examples shown in FIGS. 1 and 2. In the drawing of the illustrated embodiment, parts corresponding to those in FIG.
図1に示す実施例においては、上下段に並べて庫内の陳列室5に架設した陳列棚8に対して、図3で述べた背面パネル4の壁面には、図示のように各段の陳列棚8,および庫内天井の下面側に開口位置を合わせて左右方向に分散配列した第1パターンの冷気吹出穴4aと、陳列棚8の左右両側に開口位置を合わせて上下方向に分散配列した第2パターンの冷気吹出穴4bが併設して開口されている。 In the embodiment shown in FIG. 1, with respect to the display shelf 8 arranged in the upper and lower stages and erected in the display room 5 in the warehouse, the wall of the back panel 4 described in FIG. The first pattern of cold air outlet holes 4a distributed in the left-right direction with the opening position aligned with the lower surface side of the shelf 8 and the ceiling inside the cabinet, and the opening position aligned with the left and right sides of the display shelf 8 are distributed in the vertical direction A cold air blowing hole 4b of the second pattern is opened side by side.
そして、ショーケースの保冷運転時には、前記第1,第2パターンの冷気吹出穴4a,4bを通じてその背後に画成した冷気循環ダクト3(図3参照)から庫内前方に向けて冷気を吹き出し、ケース本体1の内箱天井面,左右側壁面,上下段に並べて陳列室5に架設した各陳列棚8の下面,および陳列棚8に搭載した商品10(アイスクリームなどの冷凍食品)の表面に沿って満遍なく冷気を流すようにしている。 And at the time of the cool operation of the showcase, the cold air is blown out from the cold air circulation duct 3 (see FIG. 3) defined behind the cold air blowing holes 4a and 4b of the first and second patterns toward the front of the interior, On the ceiling surface of the inner box of the case body 1, the left and right side wall surfaces, the lower surface of each display shelf 8 arranged in the upper and lower stages, and the surface of the product 10 (frozen food such as ice cream) mounted on the display shelf 8 The cold air is made to flow evenly along.
これにより、ショーケースの保冷運転中にケース本体1の前面に配した扉2(図3参照)の開け,閉めに伴い、図4で述べたように庫内の上部域に侵入する外気の湿気によって庫内の各部に着霜した霜層が満遍なく昇華蒸発して着霜を確実に消滅させるこができる。 As a result, as shown in FIG. 4, the humidity of the outside air entering the upper area of the cabinet as the door 2 (see FIG. 3) arranged on the front surface of the case body 1 is opened and closed during the cool operation of the showcase. As a result, the frost layer that has formed frost on each part in the chamber can be sublimated and evaporated uniformly, and the frost formation can be reliably eliminated.
次に本発明の請求項2に対応する実施例を図2で説明する。この実施例においては、先記実施例1で述べた第1パターンの冷気吹出穴4a,第2パターンの冷気吹出穴4bを、図示のように庫内陳列室5の上段側に並ぶ陳列棚8に限定して庫内上部域の背面パネル4に開口し、陳列室5の下段側に並ぶ陳列棚8に対応する前記第1パターンの冷気吹出穴4a,第2パターンの冷気吹出穴4bは穿設しないで閉口しておく。 Next, an embodiment corresponding to claim 2 of the present invention will be described with reference to FIG. In this embodiment, the first pattern cold air outlet holes 4a and the second pattern cold air outlet holes 4b described in the first embodiment are arranged on the upper side of the display chamber 5 as shown in the figure. The first pattern cold air outlet holes 4a and the second pattern cold air outlet holes 4b corresponding to the display shelves 8 arranged on the lower side of the display chamber 5 are opened. Keep it closed without setting up.
したがって、庫内の上段側に並ぶ陳列棚8の上側および左右両側域には背面パネル4に開口した第1,および第2パターンの冷気吹出穴4a,4bを通じて冷気が前方に吹き出すが、下段側の陳列棚8が並ぶ庫内の下部領域には背面側からの冷気吹き出しはなく、図1に示した実施例と比べて、冷気循環ダクト3の途中から庫内前方に向けて吹き出し分流する冷気の風量がトータル的に少なくなる。 Accordingly, the cold air blows forward through the first and second patterns of the cold air blowing holes 4a and 4b opened in the rear panel 4 on the upper and left and right side areas of the display shelf 8 arranged on the upper side of the cabinet. In the lower area in the cabinet in which the display shelves 8 are arranged, there is no cold air blowing from the back side, and compared with the embodiment shown in FIG. The total air volume is reduced.
これにより、背面パネル4の背後に画成した冷気循環ダクト3を通じて天井側の冷気吹出口3aから下方の吸込口3bに向けて庫内前面に吹き出し形成するエアカーテン気流A(図3参照)の風量が増えるので、実施例1と比べて扉開放時に庫外から庫内上部域(上段側)に流入する外気侵入量を抑制して庫内に発生する着霜量を一層効果的に低減させることができる。 As a result, the air curtain airflow A (see FIG. 3) that blows out from the ceiling-side cold air outlet 3a toward the lower inlet 3b through the cold air circulation duct 3 defined behind the back panel 4 is formed on the front surface of the interior. Since the air volume increases, the amount of frost generated in the interior can be more effectively reduced by suppressing the amount of outside air entering from the outside of the warehouse to the upper area (upper side) when the door is opened compared to the first embodiment. be able to.
