以下、本発明の一実施の形態について、図面に基づき説明する。
図１は本発明の一実施形態を示す冷凍機内蔵型ショーケースの概略構成を示す断面側面図、図２は同じく正面図、図３は通気孔カバーを閉じた状態の要部断面側面図、図４は通気孔カバーを開けた状態の要部断面側面図、図５は送風機制御部における凝縮器用送風機の制御例を示すフローチャートである。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

冷凍機内蔵型ショーケース１は、商品陳列部２の下部に設けられた架台３内に、圧縮機、凝縮器、凝縮器用送風機等の冷凍機ユニット４の構成要素を内蔵し、この冷凍機ユニットの運転によって商品陳列部２内を所定温度に冷却する。この架台３内には、冷凍機ユニット４の運転制御を行うための制御装置５が設けられていて、この制御装置５に前記凝縮器用送風機を制御する送風機制御部が含まれている。   The refrigerator-incorporated showcase 1 incorporates the components of the refrigerator unit 4 such as a compressor, a condenser, and a condenser blower in a frame 3 provided at the lower part of the product display unit 2. The inside of the commodity display unit 2 is cooled to a predetermined temperature by the operation of. A control device 5 for controlling the operation of the refrigerator unit 4 is provided in the gantry 3, and the control device 5 includes a blower control unit that controls the condenser blower.

また、架台３の前面のキックプレート３ａに外気取入用の通気孔６ａを有する通気孔カバー６が着脱可能に設けられており、該通気孔カバー６の内部側に凝縮器用フィルター７が配置され、さらに、該凝縮器用フィルター７の内部側に凝縮器８及び凝縮器用送風機（図示せず）が配置されている。   Also, a vent hole cover 6 having a vent hole 6 a for taking in outside air is detachably provided on the kick plate 3 a on the front surface of the gantry 3, and a condenser filter 7 is disposed inside the vent hole cover 6. Furthermore, a condenser 8 and a condenser blower (not shown) are disposed inside the condenser filter 7.

通気孔カバー６は、下部のヒンジ等により前傾可能に設けられており、上部側面には通気孔カバー６を前傾位置に保つレバーアーム１０が設けられている。さらに、通気孔カバー６の両側部には、凝縮器用フィルター７を保持するための凹溝部１１が設けられており、この凹溝部１１に上方から凝縮器用フィルター７が差し込まれ、凝縮器用フィルター７は、通気孔カバー６の内部側において上方に取り外し可能に取り付けられている。この通気孔カバー６は、図３に示すように、通常は架台側に閉じられているが、凝縮器用フィルター７を引き抜く際などには、図４に示すように前傾状態に開口する。   The vent hole cover 6 is provided so as to be able to tilt forward by a lower hinge or the like, and a lever arm 10 is provided on the upper side surface to keep the vent hole cover 6 in a forward tilt position. Further, a concave groove portion 11 for holding the condenser filter 7 is provided on both sides of the vent hole cover 6, and the condenser filter 7 is inserted into the concave groove portion 11 from above, and the condenser filter 7 is The air hole cover 6 is detachably mounted on the inner side of the vent hole cover 6. As shown in FIG. 3, the vent hole cover 6 is normally closed on the gantry side, but when the condenser filter 7 is pulled out, the vent hole cover 6 opens in a forward inclined state as shown in FIG.

前記制御装置５における送風機制御部は、前記凝縮器用送風機の回転方向を冷却運転時と除霜運転時とで逆方向に切り替えるように制御する。図４に示すように、ステップ１０１で冷却運転中であるか否かを判断し、冷却運転中であると判断した場合は（ＹＥＳ）、ステップ１０２に進み、冷凍機ユニットの圧縮機が運転中か否かを判断する。このステップ１０２で圧縮機が運転中であると判断した場合には（ＹＥＳ）、ステップ１０３に進んで凝縮器用送風機を正回転方向に運転する。   The blower control unit in the control device 5 performs control so that the rotation direction of the condenser blower is switched in the opposite direction between the cooling operation and the defrosting operation. As shown in FIG. 4, it is determined in step 101 whether or not the cooling operation is being performed. If it is determined that the cooling operation is being performed (YES), the process proceeds to step 102 and the compressor of the refrigerator unit is operating. Determine whether or not. If it is determined in step 102 that the compressor is in operation (YES), the process proceeds to step 103 to operate the condenser blower in the normal rotation direction.

ステップ１０１で冷却運転中ではないと判断した場合は（ＮＯ）、ステップ１０４に進み、除霜運転中であるか否かを判断し、除霜運転中であると判断した場合は（ＹＥＳ）、ステップ１０５に進んで凝縮器用送風機を逆回転方向に運転する。ステップ１０４で除霜運転中ではないと判断した場合は（ＮＯ）、すなわち、冷却運転中でもなく、除霜運転中でもないと判断されたときには、ステップ１０６に進んで凝縮器用送風機に異常が発生しているか否かを判断し、異常が発生していると判断した場合は（ＹＥＳ）、ステップ１０７に進んで凝縮器用送風機を停止させる。また、ステップ１０６で凝縮器用送風機に異常が発生していないと判断した場合は（ＮＯ）、ステップ１０８に進んで凝縮器用送風機を含めた冷凍機ユニットの電源をＯＦＦとする。   If it is determined in step 101 that the cooling operation is not being performed (NO), the process proceeds to step 104 to determine whether or not the defrosting operation is being performed. If it is determined that the defrosting operation is being performed (YES), Proceeding to step 105, the condenser blower is operated in the reverse rotation direction. If it is determined in step 104 that the defrosting operation is not being performed (NO), that is, if it is determined that the cooling operation is not being performed or the defrosting operation is not being performed, the process proceeds to step 106 and an abnormality has occurred in the condenser fan. If it is determined that there is an abnormality (YES), the process proceeds to step 107 and the condenser fan is stopped. If it is determined in step 106 that no abnormality has occurred in the condenser blower (NO), the process proceeds to step 108 and the power to the refrigerator unit including the condenser blower is turned off.

さらに、前記ステップ１０２で圧縮機が運転中ではないと判断した場合は（ＮＯ）、すなわち、冷却運転中に前記商品陳列部２内の温度が設定値に下がって冷凍機ユニットの運転が停止し、圧縮機が停止することで凝縮器８に高温の冷媒が流れない状態になったときにも、ステップ１０５に進んで凝縮器用送風機を逆回転方向に運転する。   Further, when it is determined in step 102 that the compressor is not in operation (NO), that is, during the cooling operation, the temperature in the product display unit 2 is lowered to the set value, and the operation of the refrigerator unit is stopped. Even when the compressor stops and the high-temperature refrigerant does not flow into the condenser 8, the routine proceeds to step 105 and the condenser blower is operated in the reverse rotation direction.

このように、凝縮器８を冷却するための運転を行う必要がない期間に凝縮器用送風機を冷却運転中とは逆方向に運転することにより、架台３の内部側から逆方向の風を凝縮器用フィルター７に送ることができるので、凝縮器用フィルター７の表面に付着した埃を除去することができ、凝縮器用フィルター７への埃の付着量を減少させることができる。   Thus, by operating the condenser blower in the opposite direction to that during the cooling operation during a period when it is not necessary to perform the operation for cooling the condenser 8, wind in the reverse direction from the inside of the gantry 3 is used for the condenser. Since it can send to the filter 7, the dust adhering to the surface of the filter 7 for condensers can be removed, and the adhesion amount of the dust to the filter 7 for condensers can be reduced.

したがって、凝縮器用フィルター７のメンテナンス回数を減らすことができる。また、埃の付着量が減少するので凝縮器用フィルター７の通気性が良好に保たれ、凝縮器８の放熱性能を長時間確保することができる。また、凝縮器用フィルター７に埃が付着した場合に比べて冷却効率が向上し、省エネルギーが図れるとともに、冷凍機ユニット４における高圧カットの発生も低減できる。   Therefore, the maintenance frequency of the condenser filter 7 can be reduced. Further, since the amount of dust attached is reduced, the air permeability of the condenser filter 7 is kept good, and the heat radiation performance of the condenser 8 can be ensured for a long time. Moreover, compared with the case where dust adheres to the condenser filter 7, the cooling efficiency is improved, energy saving can be achieved, and occurrence of high-pressure cut in the refrigerator unit 4 can be reduced.

また、ステップ１０２またはステップ１０３からステップ１０５に進んで凝縮器用送風機を冷却運転中とは逆方向に運転する場合、凝縮器８が店内温度近くに冷却されるまで凝縮器用送風機の正回転を継続し、逆回転運転の開始を遅らせる遅延機能を送風機制御部に設けておくことにより、凝縮器用送風機が逆回転することによって高温の凝縮器８を通った温風が通気孔カバー６からショーケース前方に流出することを防止できる。遅延機能は、タイマーを用いて所定時間逆回転を遅らせるだけの簡単な構成を採用することができ、また、温度センサーを用いて凝縮器８の温度を検出することによって行うこともできる。   When the condenser blower is operated from the step 102 or the step 103 to the step 105 in the direction opposite to that during the cooling operation, the condenser blower is continuously rotated until the condenser 8 is cooled close to the in-store temperature. By providing a delay function for delaying the start of the reverse rotation operation in the blower control unit, the hot air passing through the high-temperature condenser 8 by the reverse rotation of the condenser blower is forwarded from the vent hole cover 6 to the front of the showcase. It can prevent outflow. The delay function can employ a simple configuration that only delays reverse rotation for a predetermined time using a timer, and can also be performed by detecting the temperature of the condenser 8 using a temperature sensor.

さらに、通気孔カバー６には、凝縮器用フィルター７の表面に付着した埃を除去する埃除去手段として、上部内面に清掃爪１２が設けられるとともに、該清掃爪１２の下方に埃受けレール１３が設けられている。清掃爪１２は、凝縮器用フィルター７を通気孔カバー６から凹溝部１１に沿って上方に引き抜いて取り外す際に、清掃爪１２の先端が凝縮器用フィルター７の前面に摺接することにより、凝縮器用フィルター７の表面に付着した埃を掻き取って除去するもので、下方に設けた埃受けレール１３は、清掃爪１２で除去した埃を受け止めて床面等に落下しないようにしている。   Further, the air vent cover 6 is provided with a cleaning claw 12 on the upper inner surface as dust removing means for removing dust adhering to the surface of the condenser filter 7, and a dust receiving rail 13 is provided below the cleaning claw 12. Is provided. The cleaning claw 12 pulls the condenser filter 7 upward from the vent cover 6 along the groove 11 and removes the condenser claw 12 by sliding the tip of the cleaning claw 12 against the front surface of the condenser filter 7. The dust receiving rail 13 provided at the lower side receives the dust removed by the cleaning claw 12 so that it does not fall on the floor surface or the like.

このような清掃爪１２と埃受けレール１３とを設けることにより、凝縮器用フィルター７を通気孔カバー６から取り外す際に、凝縮器用フィルター７の表面に付着した比較的大きな埃を手を汚さずに除去することができ、また、埃受けレール１３で受けた埃は、電気掃除機等で簡単に取り除くことができるので、凝縮器用フィルター７の表面部分の清掃を簡単に行うことができる。   By providing the cleaning claw 12 and the dust receiving rail 13 as described above, when removing the condenser filter 7 from the vent hole cover 6, relatively large dust adhering to the surface of the condenser filter 7 can be obtained without staining the hands. Since the dust received by the dust receiving rail 13 can be easily removed with a vacuum cleaner or the like, the surface portion of the condenser filter 7 can be easily cleaned.

したがって、凝縮器用送風機の回転方向を切り替える制御と、凝縮器用フィルター７の埃除去手段とを採用することにより、簡単なメンテナンスを行うだけで凝縮器用フィルター７の通気性を長期間にわたって確実に良好に保つことができ、凝縮器の放熱性の向上から冷凍機ユニットの冷却効率が向上し、より一層の省エネルギー化を図ることができる。   Therefore, by adopting the control for switching the rotation direction of the condenser blower and the dust removing means of the condenser filter 7, the air permeability of the condenser filter 7 can be reliably improved over a long period of time only by performing simple maintenance. The cooling efficiency of the refrigerator unit can be improved by improving the heat dissipation of the condenser, and further energy saving can be achieved.

なお、冷凍機内蔵型ショーケースの構成、構造は特に限定されるものではなく、各種形式の冷凍機内蔵型ショーケースに適用することができる。   The configuration and structure of the refrigerator built-in showcase are not particularly limited, and can be applied to various types of refrigerator-mounted showcases.
