かかる構成の自動販売機1によれば、冷温切換室16に第2冷却ユニット50の圧縮機51を配置したので、圧縮機51の発熱による圧縮機51からの排熱によって冷温切換室16を加温できる。これにより、電気ヒータで加熱する従来機に比べて消費電力量を抑制することができ、自動販売機の省エネ化を図ることができる。また、第2冷却ユニット50の放熱器52を冷温切換室16に配置したので、放熱器52における冷媒の放熱で冷温切換室16を加温できるので、より省エネ化を図ることができる。 According to the vending machine 1 having such a configuration, the compressor 51 of the second cooling unit 50 is disposed in the cooling / temperature switching chamber 16, so that the cooling / temperature switching chamber 16 is added by exhaust heat from the compressor 51 due to heat generated by the compressor 51. Can warm. Thereby, compared with the conventional machine heated with an electric heater, power consumption can be suppressed and energy saving of a vending machine can be achieved.

また、冷温切換室16下部に配置する圧縮機51、放熱器52及び吸熱器32が、商品収納コラム19から落下した商品を商品搬出口22へ搬送するデリバリシュート(図示せず)と干渉しないように、冷温切換室16下部の上下仕切板25Bの位置を、他の冷温切換室17及び冷却専用室18の下部の上下仕切板25Aより低い位置に配置した。これにより、冷温切換室16の商品収容容積を従来機と同じにでき、従来と同様の商品収納容積を有する自動販売機1を提供できる。 Further, the compressor 51, the radiator 52, and the heat absorber 32 disposed at the lower part of the cold / warm switching chamber 16 do not interfere with a delivery chute (not shown) that conveys the product dropped from the product storage column 19 to the product delivery port 22.

The refrigerant piping portion connecting the heat absorber 54 of the cooling unit 50 and the capillary tube 53 and the capillary tube 38A of the first cooling unit 30 uses a step portion between the first upper and lower partition plates 25A and the second upper and lower partition plates 25B. Since the piping is performed in the horizontal direction, the refrigerant piping 44 can be simplified, and the refrigerant piping 44 can be easily attached.
また、冷温切換室16に圧縮機51を配置する冷却ユニット50の他に、第1冷却ユニット30を設け、その圧縮機35を機械室24の略中央部配置した。これにより、自動販売機1の重量バランスを確保でき、設置したときの安定性を確保できる。 In addition to the cooling unit 50 in which the compressor 51 is disposed in the cold / warm switching chamber 16, the first cooling unit 30 is provided, and the compressor 35 is disposed in the substantially central portion of the machine chamber 24.

また、本実施形態では、加温可能な収納室(冷温切換室16)の商品収容容積を従来機と同程度確保するために、加温可能な収納室の下部に位置する上下仕切板位置を他の室の下部に位置する上下仕切板位置よりも低くしたが、加温可能な収納室の商品収容容積を縮小して加温可能な収納室の下部の上下仕切板位置と他の室の下部の上下仕切板位置とを同じ高さとしてもよく、この場合、従来と同様に一枚の平板状の上下仕切板を用いることができ、閉塞板28やその組み付け構造が省略でき、自動販売機の製造コストが低減される。
In the present embodiment, the compressor of the cooling unit (second cooling unit) is arranged on the bottom surface of the warming storage chamber (cold temperature switching chamber 16). The arrangement may be any storage room that can be heated, and not necessarily the bottom surface of the storage room.
Moreover, in this embodiment, in order to ensure the product accommodation volume of the storage room (cold temperature switching room 16) which can be heated to the same extent as the conventional machine, the upper and lower partition plate positions located at the lower part of the storage room which can be heated are set. Although lower than the upper and lower partition plate positions located in the lower part of the other chambers, the product storage volume of the storage room that can be heated is reduced, and the upper and lower partition plate positions in the lower part of the storage room that can be heated and the other room The lower upper and lower partition plates may have the same height. In this case, a single flat upper and lower partition plate can be used as in the conventional case, the closing plate 28 and its assembly structure can be omitted, and vending The manufacturing cost of the machine is reduced.
次に、本発明の自動販売機に適用する冷却ユニットについて説明する。
本実施形態の自動販売機1では、2つの冷却ユニット設けている。即ち、冷却ユニットとして冷温切換室16,17と冷却専用室18を冷却する第1冷却ユニット30と、冷温切換室16を加温する第2冷却ユニット50とを設け、第1冷却ユニット30の各吸熱器32,33,34を、冷温切換室16,17と冷却専用室18にそれぞれ配置し、第2冷却ユニット50の圧縮機51と放熱器52を冷温切換室16に配置している。そして、冷温切換室16における第1冷却ユニット30の吸熱器32と第2冷却ユニット50の圧縮機51及び放熱器52の配置構成を、冷温切換室16の前方側から後方側に向けて、第1冷却ユニット30の吸熱器32、第2冷却ユニット50の圧縮機51、放熱器52の順で配置している。
Next, the cooling unit applied to the vending machine of the present invention will be described.
In the vending machine 1 of the present embodiment, two cooling units are provided. That is, as the cooling unit, a first cooling unit 30 for cooling the cooling / temperature switching chambers 16 and 17 and the cooling dedicated chamber 18 and a second cooling unit 50 for heating the cooling / temperature switching chamber 16 are provided. The heat absorbers 32, 33, and 34 are disposed in the cooling / temperature switching chambers 16 and 17 and the cooling dedicated chamber 18, respectively, and the compressor 51 and the radiator 52 of the second cooling unit 50 are disposed in the cooling / temperature switching chamber 16. Then, the arrangement configuration of the heat absorber 32 of the first cooling unit 30 and the compressor 51 and the radiator 52 of the second cooling unit 50 in the cold / temperature switching chamber 16 is changed from the front side to the rear side of the cold / temperature switching chamber 16. The heat absorber 32 of the first cooling unit 30, the compressor 51 of the second cooling unit 50, and the radiator 52 are arranged in this order.
この場合、第2冷却ユニット50の冷媒として、例えばR1234yfを使用し、圧縮機51として冷媒を超臨界圧力未満で圧縮する圧縮機を用いる。尚、第2冷却ユニット50の冷媒として、R134a、又はR1234ze等を用いてもよい。第1冷却ユニット30の冷媒としては、本実施形態では、例えば二酸化炭素(CO2)とするが、特に限定はしない。 In this case, for example, R1234yf is used as the refrigerant of the second cooling unit 50, and a compressor that compresses the refrigerant below the supercritical pressure is used as the compressor 51. Note that R134a, R1234ze, or the like may be used as the refrigerant of the second cooling unit 50. In the present embodiment, the refrigerant of the first cooling unit 30 is, for example, carbon dioxide (CO 2 ), but is not particularly limited.
かかる構成によれば、冷温切換室16,17及び冷却専用室18では、送風機44,45,46によって、後側から前側、上方、後部ダクト(図示せず)の順で室内の空気が流れる。このため、冷温切換室16内において、第1冷却ユニット30と第2冷却ユニット50が稼働状態にあるとき、例えば圧縮機51の表面温度が70℃、圧縮機51の吐出側の冷媒配管温度が55℃(放熱器51の入口温度と出口温度も同じ(第2冷却ユニット50の冷媒は等温変化))とした場合、圧縮機51を冷却した後の空気温度は放熱器52の温度より低く、放熱器52からの放熱が可能となり、放熱器51の効率を高めることができる。しかし、圧縮機51と放熱器52の配置を逆にした場合、即ち、冷温切換室16の前方側から後方側に向けて、第1冷却ユニット30の吸熱器32、第2冷却ユニット50の放熱器52、圧縮機51の順で配置した場合には、圧縮機51を冷却した後の空気温度が放熱器52の放熱温度より高く、放熱器52が放熱し難くなってしまう。 According to such a configuration, in the cool / warm switching chambers 16 and 17 and the cooling exclusive chamber 18, indoor air flows from the rear side to the front side, the upper side, and the rear duct (not shown) by the blowers 44, 45 and 46. For this reason, when the 1st cooling unit 30 and the 2nd cooling unit 50 are in an operation state in the cold temperature switching chamber 16, for example, the surface temperature of the compressor 51 is 70 degreeC, and the refrigerant | coolant piping temperature of the discharge side of the compressor 51 is the temperature. When the temperature is 55 ° C. (the inlet temperature and the outlet temperature of the radiator 51 are also the same (the refrigerant of the second cooling unit 50 changes isothermally)), the air temperature after cooling the compressor 51 is lower than the temperature of the radiator 52, Heat dissipation from the radiator 52 is possible, and the efficiency of the radiator 51 can be increased. However, when the arrangement of the compressor 51 and the radiator 52 is reversed, that is, from the front side to the rear side of the cold / warm switching chamber 16, the heat sink 32 of the first cooling unit 30 and the heat radiation of the second cooling unit 50 are performed. When the compressor 52 and the compressor 51 are arranged in this order, the air temperature after cooling the compressor 51 is higher than the heat dissipation temperature of the radiator 52, and the radiator 52 becomes difficult to dissipate heat.

図13は、冷却ユニットの別の配置構成における冷媒回路の構成図を示す。
この冷媒回路は、冷温切換室16における第1冷却ユニット30の吸熱器32と第2冷却ユニット50の圧縮機51及び放熱器52の配置構成を、冷温切換室16の前方側から後方側に向けて、第1冷却ユニット30の吸熱器32、第2冷却ユニット50の放熱器52、第2冷却ユニット50の圧縮機51の順で配置している。即ち、図5の冷媒回路の配置構成に対して、第2冷却ユニット50の放熱器52と圧縮機51の位置を入れ替えて構成されている。
FIG. 13 shows a configuration diagram of a refrigerant circuit in another arrangement configuration of the cooling unit.
In this refrigerant circuit, the arrangement of the heat absorber 32 of the first cooling unit 30 and the compressor 51 and the radiator 52 of the second cooling unit 50 in the cold / temperature switching chamber 16 is directed from the front side to the rear side of the cold / temperature switching chamber 16. The heat absorber 32 of the first cooling unit 30, the radiator 52 of the second cooling unit 50, and the compressor 51 of the second cooling unit 50 are arranged in this order. That is, the arrangement of the refrigerant circuit in FIG. 5 is configured by replacing the positions of the radiator 52 and the compressor 51 of the second cooling unit 50.
この場合、第2冷却ユニット50の冷媒として、二酸化炭素(CO2)を使用し、圧縮機51として冷媒を超臨界圧力以上で圧縮する圧縮機を用いる。尚、第1冷却ユニット30の冷媒としては、本実施形態では例えばCO2とするが、特に限定はしない。 In this case, carbon dioxide (CO 2 ) is used as the refrigerant of the second cooling unit 50, and a compressor that compresses the refrigerant at a supercritical pressure or higher is used as the compressor 51. The refrigerant of the first cooling unit 30 is, for example, CO 2 in the present embodiment, but is not particularly limited.
かかる構成によれば、冷温切換室16,17及び冷却専用室18での室内空気が、後側から前側、上方、後部ダクト(図示せず)の順で流れており、冷温切換室16内において、第1冷却ユニット30と第2冷却ユニット50が稼働状態にあるとき、例えば圧縮機51の表面温度が80℃、圧縮機51の吐出側の冷媒配管温度が120℃(放熱器51の入口温度)、放熱器51の出口温度が60℃(第2冷却ユニット50の冷媒であるCO2は等温変化ではない)とした場合、圧縮機51を冷却した後の室内雰囲気温度は放熱器52の温度より低く、放熱器52からの放熱が可能となる。しかし、圧縮機51と放熱器52の配置を逆にした場合、即ち、図5のように、冷温切換室16の前方側から後方側に向けて、第1冷却ユニット30の吸熱器32、第2冷却ユニット50の圧縮機51、放熱器52の順で配置した場合には、圧縮機51の温度が低下し、放熱器52で放熱した後の空気温度が圧縮機51の表面温度より高いので、圧縮機51を冷却し難くなってしまう。 According to such a configuration, the room air in the cooling / temperature switching chambers 16, 17 and the cooling dedicated chamber 18 flows in the order from the rear side to the front side, the upper side, and the rear duct (not shown). When the first cooling unit 30 and the second cooling unit 50 are in operation, for example, the surface temperature of the compressor 51 is 80 ° C., the refrigerant pipe temperature on the discharge side of the compressor 51 is 120 ° C. (the inlet temperature of the radiator 51). ) When the outlet temperature of the radiator 51 is 60 ° C. (CO 2 as the refrigerant of the second cooling unit 50 is not isothermal), the indoor ambient temperature after cooling the compressor 51 is the temperature of the radiator 52 The heat dissipation from the radiator 52 is possible. However, when the arrangement of the compressor 51 and the radiator 52 is reversed, that is, as shown in FIG. 5, from the front side to the rear side of the cold temperature switching chamber 16, the heat absorber 32 of the first cooling unit 30, 2 When the compressor 51 and the radiator 52 of the cooling unit 50 are arranged in this order, the temperature of the compressor 51 decreases, and the air temperature after the heat radiation by the radiator 52 is higher than the surface temperature of the compressor 51. This makes it difficult to cool the compressor 51.
図14は、図13の冷却ユニットの配置構成における別の冷媒回路例を示す構成図であり、この冷媒回路は、第2冷却ユニット50の圧縮機51と放熱器52の位置が異なる以外は、図9の冷媒回路と同じ構成である。 FIG. 14 is a configuration diagram showing another refrigerant circuit example in the arrangement configuration of the cooling unit of FIG. 13, and this refrigerant circuit is different except that the positions of the compressor 51 and the radiator 52 of the second cooling unit 50 are different. It is the same structure as the refrigerant circuit of FIG.
かかる構成では、図9に示す冷媒回路構成と同様、第2冷却ユニット50の稼働時に、第2冷却ユニット50を冷却専用室18の冷却に利用することができるようになる。 With this configuration, the second cooling unit 50 can be used for cooling the cooling dedicated chamber 18 when the second cooling unit 50 is in operation, as in the refrigerant circuit configuration shown in FIG.
図15は、図14の冷媒回路の変形例を示す構成図であり、この冷媒回路は、第2冷却ユニット50の圧縮機51と放熱器52の位置が異なる以外は、図10の冷媒回路と同じ構成である。 FIG. 15 is a block diagram showing a modification of the refrigerant circuit of FIG. 14. This refrigerant circuit differs from the refrigerant circuit of FIG. 10 except that the positions of the compressor 51 and the radiator 52 of the second cooling unit 50 are different. It is the same configuration.
かかる構成では、図10に示す冷媒回路構成と同様、第2冷却ユニット50の稼働時に、三方弁57の切換えにより、第2冷却ユニット50を冷却専用室18の冷却に利用したり、利用するのを止めたりすることが選択できるようになる。 In this configuration, as in the refrigerant circuit configuration shown in FIG. 10, the second cooling unit 50 is used for cooling the cooling dedicated chamber 18 or is used by switching the three-way valve 57 when the second cooling unit 50 is in operation. You can choose to stop.
図16は、図13の冷却ユニットの配置構成における更に別の冷媒回路例を示す構成図であり、この冷媒回路は、第2冷却ユニット50の圧縮機51と放熱器52の位置が異なる以外は、図11の冷媒回路と同じ構成である。 FIG. 16 is a configuration diagram showing still another refrigerant circuit example in the arrangement configuration of the cooling unit in FIG. 13, and this refrigerant circuit is different except that the positions of the compressor 51 and the radiator 52 of the second cooling unit 50 are different. The configuration is the same as that of the refrigerant circuit of FIG.
かかる構成では、図11に示す冷媒回路構成と同様、第2冷却ユニット50の稼働時に、冷温切換室17と冷却専用室18の冷却に第2冷却ユニット50を利用することができ、開閉弁57A,57Bの開閉制御により、冷温切換室17又は冷却専用室18だけに利用するか、冷温切換室17と冷却専用室18の両室の冷却に利用するか、を選択することができるようになる。 In this configuration, similar to the refrigerant circuit configuration shown in FIG. 11, the second cooling unit 50 can be used for cooling the cooling / temperature switching chamber 17 and the cooling dedicated chamber 18 during operation of the second cooling unit 50, and the on-off valve 57A. , 57B can be used to select whether to use only the cooling / cooling switching chamber 17 or the cooling dedicated chamber 18 or to cool both the cooling / cooling switching chamber 17 and the cooling dedicated chamber 18. .
図17は、図16の冷媒回路の変形例を示す構成図であり、この冷媒回路は、第2冷却ユニット50の圧縮機51と放熱器52の位置が異なる以外は、図12の冷媒回路と同じ構成である。 FIG. 17 is a configuration diagram showing a modification of the refrigerant circuit of FIG. 16, which is the same as the refrigerant circuit of FIG. 12 except that the positions of the compressor 51 and the radiator 52 of the second cooling unit 50 are different. It is the same configuration.
かかる構成では、図12に示す冷媒回路構成と同様、第2冷却ユニット50の稼働時に、開閉弁59A,59B,59Cの開閉制御により、第2冷却ユニット50を、冷温切換室17又は冷却専用室18だけに利用するか、冷温切換室17と冷却専用室18の両室の冷却に利用するか、第2冷却ユニット50を冷温切換室17と冷却専用室18の冷却に利用するのを止めたりするか、を選択できるようになる。 In this configuration, similarly to the refrigerant circuit configuration shown in FIG. 12, when the second cooling unit 50 is in operation, the second cooling unit 50 is controlled by the open / close valves 59A, 59B, 59C to control the second cooling unit 50 to the cooling / temperature switching chamber 17 or the cooling dedicated chamber. 18 is used only for cooling, the cooling / cooling switching chamber 17 and the cooling dedicated chamber 18 are cooled, or the second cooling unit 50 is stopped from being used for cooling the cooling / cooling switching chamber 17 and the cooling dedicated chamber 18. You will be able to choose.
また、図5、図9〜図17に示す冷媒回路構成において、第1冷却ユニット30と第2冷却ユニット50は、冷温切換室16,17と冷却専用室18の温度検出用温度センサの検出温度に基づいて圧縮機31,51をON/OFFするが、第2冷却ユニット50の圧縮機51のON動作に同期させて第1冷却ユニット30の圧縮機31をON駆動するとよい。このようにして、第1冷却ユニット30側の機械室24に配置した放熱器35の放熱を第2冷却ユニット50側の機械室24に配置した吸熱器54で吸熱させることで、第1冷却ユニット30側の放熱器35の放熱を第2冷却ユニット50側の吸熱器54で無駄なく回収することができ、第2冷却ユニット50の吸熱器54が単に大気から吸熱するよりも第2冷却ユニット50の効率を高めることができる。ただし、冷温切換室17や冷却専用室18の室温がある所定温度以上になった場合は、商品温度を維持するため、第2冷却ユニット50側の圧縮機51の駆動状態に関係なく、第1冷却ユニット30側の圧縮機31をON駆動する構成とすることが望ましい。 Further, in the refrigerant circuit configurations shown in FIGS. 5 and 9 to 17, the first cooling unit 30 and the second cooling unit 50 are detected by the temperature detection temperature sensors in the cold temperature switching chambers 16 and 17 and the cooling dedicated chamber 18. The compressors 31 and 51 are turned ON / OFF based on the above, but the compressor 31 of the first cooling unit 30 may be turned ON in synchronization with the ON operation of the compressor 51 of the second cooling unit 50. In this manner, the heat radiation of the radiator 35 arranged in the machine room 24 on the first cooling unit 30 side is absorbed by the heat absorber 54 arranged in the machine room 24 on the second cooling unit 50 side, whereby the first cooling unit. The heat radiation of the heat radiator 35 on the 30 side can be recovered without waste by the heat absorber 54 on the second cooling unit 50 side, so that the heat sink 54 of the second cooling unit 50 simply absorbs heat from the atmosphere. Can increase the efficiency. However, when the room temperature of the cooling / cooling switching chamber 17 or the cooling exclusive chamber 18 exceeds a predetermined temperature, the first temperature is maintained regardless of the driving state of the compressor 51 on the second cooling unit 50 side in order to maintain the product temperature. It is desirable that the compressor 31 on the cooling unit 30 side is driven ON.
尚、圧縮機を1つとして、これを加温可能な収納室内の下部に配置し、機械室に圧縮機を配置しない構成でもよいが、この場合、重量バランス的に自動販売機の設置安定性が損なわれる虞れがある。従って、上記実施形態のように、機械室に圧縮機を配置し、加温可能な収納室内の下部には他の圧縮機を配置する構成が望ましい。
また、加温可能な収納室を冷温切換室としたが、加温室であってもよく、この場合、冷温切換室16における第1冷却ユニット30の吸熱器32を省略してもよい。
また、送風機44,45,46は、冷温切換室16の最後方側、即ち、図5〜図12においては放熱器52の後側、図13〜図17においては圧縮機51の後側に配置してもよい。ただし、送風機の特性上、空気の流れを阻害するもの(特に熱交換器(放熱器や吸熱器))に対して、空気を押し込む方向より空気を吸い出す方向の方が好ましく、本実施形態のような配置が望ましい。
In addition, it is possible to adopt a configuration in which a single compressor is disposed in the lower part of the storage room where heating is possible and no compressor is disposed in the machine room, but in this case, the installation stability of the vending machine is balanced in weight. May be damaged. Therefore, as in the above-described embodiment, it is desirable that the compressor is disposed in the machine room, and another compressor is disposed in the lower part of the storage chamber that can be heated.
Moreover, although the storage room which can be heated was made into the cold temperature switching room, it may be a warming room. In this case, the heat absorber 32 of the first cooling unit 30 in the cold temperature switching room 16 may be omitted.
The blowers 44, 45, and 46 are arranged on the rearmost side of the cooling / temperature switching chamber 16, that is, on the rear side of the radiator 52 in FIGS. 5 to 12 and on the rear side of the compressor 51 in FIGS. May be. However, due to the characteristics of the blower, the direction that sucks out air is preferable to the direction that pushes in air (especially heat exchangers (heat radiators and heat sinks)) that obstruct the air flow. Is desirable.
