Description

本発明は、保存温度の異なる商品を同時に収納可能なショーケースに関するものである。   The present invention relates to a showcase that can simultaneously store products having different storage temperatures.

従来、この種のショーケースとしては、前面に開口部を有するショーケース本体と、ショーケース本体内に形成された商品収納部と、商品収納部に配置された上下複数段の商品棚と、商品収納部の少なくとも背面側に上下方向に延びるように設けられた通風路と、通風路内に配置された冷却器及び送風機とを備え、ショーケース本体の開口部の下端側に設けられた空気吸入口から通風路に吸入した空気を冷却し、開口部の上端側に設けられた空気吐出口から吐出することにより、商品棚に陳列された商品を冷却するようにしたものが知られている。   Conventionally, as a showcase of this type, a showcase body having an opening on the front surface, a product storage section formed in the showcase body, a plurality of upper and lower product shelves arranged in the product storage section, and a product An air intake provided at the lower end side of the opening of the showcase body, comprising a ventilation path provided to extend in the vertical direction at least on the back side of the storage section, and a cooler and a blower disposed in the ventilation path. There has been known a system that cools the product that is displayed on the product shelf by cooling the air sucked into the ventilation path from the mouth and discharging it from the air discharge port provided on the upper end side of the opening.

JP 2004-286433 A

従来のショーケースでは、商品収納部を冷却する場合、空気吸入口から通風路に吸入した空気を冷却器によって所定の温度に冷却して空気吐出口または冷気流通ダクトから吐出するようにしているため、例えば商品収納部の下側を第1の所定温度(3℃)に冷却し、商品収納部の上側を第2の所定温度(5℃)に冷却するように、商品収納部を同時に二温度以上の冷却温度に設定することはできない。このため、冷却温度の異なる商品を収納する場合には、それぞれ異なるショーケースの設置が必要となり、売り場面積の小さい店舗内において商品を効率的に収納することができないという問題点があった。   In the conventional showcase, when the product storage unit is cooled, the air sucked into the ventilation path from the air suction port is cooled to a predetermined temperature by the cooler and discharged from the air discharge port or the cold air circulation duct. For example, the product storage unit is simultaneously cooled to a first predetermined temperature (3 ° C.) and the product storage unit is cooled to a second predetermined temperature (5 ° C.) at the same time so that the lower side of the product storage unit The above cooling temperature cannot be set. For this reason, when goods with different cooling temperatures are stored, it is necessary to install different showcases, and there is a problem that the goods cannot be efficiently stored in a store with a small sales area.

本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、冷却温度の異なる商品及び加熱する商品を同時に収納することができるショーケースを提供することにある。   The present invention has been made in view of the above problems, and an object thereof is to provide a showcase capable of simultaneously storing products having different cooling temperatures and products to be heated.

本発明は前記目的を達成するために、前面に開口部を有するショーケース本体と、ショーケース本体内に設けられた商品収納部と、商品収納部に配置された上下複数段の商品棚と、商品収納部の少なくとも背面側に上下方向に延びるように設けられた通風路と、通風路内に設けられた送風機とを備えたショーケースにおいて、前記商品収納部の背面側に位置する通風路の少なくとも下端側を商品収納部側とショーケース本体の内面側とに仕切る仕切部材と、仕切部材の商品収納部側及びショーケース本体の内面側を流通する空気をそれぞれ異なる温度に冷却可能な冷却器と、仕切部材の商品収納部側の通風路の上下方向所定位置を上下方向に仕切るとともに、空気を前方に流通させて商品収納部に吐出可能な冷気流通ダクトとを備えている。   To achieve the above object, the present invention provides a showcase body having an opening on the front surface, a product storage section provided in the showcase body, a plurality of upper and lower product shelves disposed in the product storage section, In a showcase comprising a ventilation path provided so as to extend in the vertical direction at least on the back side of the product storage unit, and a blower provided in the ventilation path, a ventilation path located on the back side of the product storage unit A partition member that partitions at least the lower end side into a product storage portion side and an inner surface side of the showcase body, and a cooler capable of cooling the air flowing through the product storage portion side of the partition member and the inner surface side of the showcase body to different temperatures. And a cold air circulation duct that divides the predetermined position in the vertical direction of the ventilation path on the product storage portion side of the partition member in the vertical direction and allows air to flow forward and be discharged to the product storage portion.

これにより、仕切部材の商品収納部側を流通する空気が冷気流通ダクトによって通風路の上下方向所定位置から前方に流通することから、冷却温度の異なる空気がそれぞれ商品収納部に吐出され、商品収納部が同時に異なる冷却温度に冷却される。   As a result, air flowing through the product storage portion side of the partition member flows forward from a predetermined position in the up-and-down direction of the ventilation path by the cold air distribution duct, so that air having different cooling temperatures is discharged to the product storage portion, respectively. The parts are simultaneously cooled to different cooling temperatures.

本発明によれば、冷却温度の異なる空気をそれぞれ商品収納部に吐出し、商品収納部を同時に異なる冷却温度に冷却することができるので、商品収納部に冷却温度の異なる商品を同時に収納することが可能となる。   According to the present invention, since air having different cooling temperatures can be discharged to the product storage unit and the product storage unit can be simultaneously cooled to different cooling temperatures, products having different cooling temperatures can be stored simultaneously in the product storage unit. Is possible.

以上のように構成されたショーケースにおいて、商品収納部17に収納される商品の全てを所定温度(3℃または5℃)に冷却する場合には、冷気流通ダクト40を使用することなく送風機37を運転し、第1及び第2の電磁弁54a,54bの一方を開放して他方を閉鎖する。送風機37によって空気吸入口31から通風路30内に流入した空気は、第1の冷却器34aまたは第2の冷却器34bによって冷却され、空気吐出口32から吐出されてショーケース本体10の開口部にエアカーテンを形成する。これにより、商品収納部17に収納される商品は、所定温度に冷却される。また、ショーケースが設置される店舗内の温度が高い場合など、冷却負荷が大きく冷却能力が不足する場合には、第1及び第2の電磁弁54a,54bを同時に開放し、通風路30内に流入した空気を第1及び第2の冷却器34a,34bによって冷却する。   In the showcase configured as described above, when all the products stored in the product storage unit 17 are cooled to a predetermined temperature (3 ° C. or 5 ° C.), the blower 37 is used without using the cold air duct 40. Is operated, one of the first and second electromagnetic valves 54a and 54b is opened and the other is closed. The air that has flowed into the ventilation path 30 from the air inlet 31 by the blower 37 is cooled by the first cooler 34a or the second cooler 34b, discharged from the air discharge port 32, and the opening of the showcase body 10 Form an air curtain. Thereby, the product stored in the product storage unit 17 is cooled to a predetermined temperature. Further, when the cooling load is large and the cooling capacity is insufficient, such as when the temperature in the store where the showcase is installed is high, the first and second electromagnetic valves 54a and 54b are opened at the same time, and the inside of the ventilation path 30 The air that has flowed into is cooled by the first and second coolers 34a and 34b.

また、商品収納部17に収納される商品の全てを加熱する場合には、送風機37を運転することなく第1及び第2の電磁弁54a,54bを閉鎖し、各商品棚20の棚板21に設けられた電気ヒータ23に通電する。これにより、棚板21上に載置される商品は、電気ヒータ23によって加熱される。   Further, when heating all the products stored in the product storage unit 17, the first and second electromagnetic valves 54 a and 54 b are closed without operating the blower 37, and the shelf plate 21 of each product shelf 20. The electric heater 23 provided in is energized. Thereby, the product placed on the shelf board 21 is heated by the electric heater 23.

また、商品収納部17の上部側の商品棚20に載置される商品を加熱するとともに、下部側の商品棚20に載置される商品を所定温度(3℃または5℃)に冷却する場合には、図5に示すように、加熱する商品が載置される商品棚20のうち、最下段の商品棚20の下部に冷気流通ダクト40を取付け、仕切部42の後端側を断熱壁11の内面に当接させるとともに、送風機37を運転し、第1及び第2の電磁弁54a,54bの一方を開放して他方を閉鎖する。本実施形態において、加熱する商品を載置可能な商品棚20は、最上段の商品棚20から3段目までの商品棚20となる。送風機37によって開口部の下端の空気吸入口31から流入した空気は、第1または第2の冷却器34a,34bによって冷却された後に冷気流通ダクト40を流通してダクト部41の前端側から吐出される。これにより、商品収納部17に収納される商品は、商品収納部17の下部側に位置する商品棚20に載置される商品が冷却され、商品収納部17の上部側の商品棚20に載置される商品がそれぞれ電気ヒータ23によって加熱される。   In addition, when the product placed on the product shelf 20 on the upper side of the product storage unit 17 is heated, the product placed on the product shelf 20 on the lower side is cooled to a predetermined temperature (3 ° C. or 5 ° C.). As shown in FIG. 5, among the product shelves 20 on which products to be heated are placed, a cold air circulation duct 40 is attached to the lower part of the lowest product shelf 20, and the rear end side of the partition 42 is insulated by a heat insulating wall. 11, the blower 37 is operated, and one of the first and second electromagnetic valves 54a and 54b is opened and the other is closed. In the present embodiment, the product shelves 20 on which products to be heated can be placed are the product shelves 20 from the uppermost product shelf 20 to the third product shelf 20. The air flowing in from the air inlet 31 at the lower end of the opening by the blower 37 is cooled by the first or second cooler 34a, 34b, then flows through the cold air circulation duct 40 and is discharged from the front end side of the duct portion 41. Is done. As a result, the product stored in the product storage unit 17 is cooled by the product placed on the product shelf 20 located on the lower side of the product storage unit 17 and placed on the product shelf 20 on the upper side of the product storage unit 17.
