Description

本発明は、前面を開口した商品収納庫の内壁面に断熱板を配置し断熱仕切り板により商品収納庫を左右に区画した自動販売機の断熱構造に関するものである。 The present invention relates to a heat insulating structure of a vending machine in which a heat insulating plate is arranged on an inner wall surface of a product storage with an open front, and the product storage is divided into left and right by a heat insulating partition plate.

従来の自動販売機は、商品収納庫の背面に配設される断熱背板が、１枚の板状体で構成されて外箱の背板に沿って取り付けられ、また、商品収納庫の底面に配設される断熱底板も、１枚の板状体で構成されて外箱の収納庫底板に沿って取り付けられ、また、商品収納庫の天井面に配設される断熱天板も、１枚の板状体で構成されて外箱の収納庫天井板に沿って取り付けられ、その断熱背板と断熱底板と断熱天板の庫内側の面に対して、断熱仕切り板の端面が当接されて取り付けられていた。 In a conventional vending machine, a heat insulating back plate disposed on the back of the product storage is composed of a single plate and attached along the back plate of the outer box, and the bottom of the product storage The heat-insulating bottom plate disposed on the top is also composed of a single plate-like body and is attached along the storage bottom plate of the outer box, and the heat-insulating top plate disposed on the ceiling surface of the product storage is also 1 It is composed of a single plate and attached along the storage ceiling plate of the outer box, and the end face of the heat insulating partition plate contacts the inner surface of the heat insulating back plate, heat insulating bottom plate, and heat insulating top plate. Had been attached.

ところで、外箱は、比較的薄い金属製の板材で構成されるため、特に、面積の大きな背板側では、中央部が外側に凸となるように反る現象が発生しやすい。 By the way, since the outer box is composed of a relatively thin metal plate, a phenomenon of warping so that the central portion is convex outward tends to occur particularly on the back plate side having a large area.

外箱の背板に、このような反りが生じると、断熱背板も反って、そのために、断熱背板と断熱仕切り板の端面との間に隙間が生じると、断熱仕切り板により商品収納庫を加温庫と冷却庫とに左右に区画した自動販売機では、加温庫内から冷却庫内への熱移動が多くなり、加温庫内を加温し冷却庫内を冷却するための消費電力量が増加する。 When such a warp occurs in the back plate of the outer box, the heat insulating back plate also warps. Therefore, if a gap is generated between the heat insulating back plate and the end face of the heat insulating partition plate, the heat insulating partition plate causes the product storage to be stored. In the vending machine that is divided into a heating chamber and a cooling chamber on the left and right, the heat transfer from the heating chamber to the cooling chamber increases, and the heating chamber is heated to cool the cooling chamber. Power consumption increases.

そこで、クッション材を断熱仕切り板の後端面に取り付けると共に、断熱背板側にもクッション材が当接する部分に両面粘着テープを貼り付けて、クッション材によって断熱背板と断熱仕切り板の後端面との間の隙間を埋めて、加温庫内から冷却庫内への熱移動を減らすことが提案された（例えば、特許文献１参照）。 Therefore, the cushion material is attached to the rear end surface of the heat insulating partition plate, and a double-sided adhesive tape is attached to the portion where the cushion material contacts the heat insulating back plate side, and the heat insulating back plate and the rear end surface of the heat insulating partition plate are attached by the cushion material. It has been proposed to reduce the heat transfer from the inside of the heating chamber to the inside of the cooling chamber by filling the gap between them (for example, see Patent Document 1).

しかしながら、上記特許文献１に記載の従来の自動販売機では、断熱背板の反りが比較的大きい場合は、クッション材の圧縮度低下により、クッション材によるシール性が低下し、加温庫内から冷却庫内への熱移動が多くなるという課題を有していた。 However, in the conventional vending machine described in Patent Document 1, when the warp of the heat insulating back plate is relatively large, the sealing performance by the cushion material is reduced due to a decrease in the compression degree of the cushion material, and from the inside of the heating chamber. There was a problem that heat transfer into the refrigerator increased.

また、経年変化により、両面粘着テープの粘着性が低下し、クッション材の弾力性も低下すると、断熱背板と断熱仕切り板の端面との間に隙間が生じる可能性があるという課題を有していた。 In addition, when the adhesiveness of the double-sided adhesive tape decreases and the elasticity of the cushioning material also decreases due to secular change, there is a problem that a gap may be generated between the heat insulating back plate and the end face of the heat insulating partition plate. It was.

本発明は、上記従来の課題を解決するものであり、断熱仕切り板により商品収納庫を加温庫と冷却庫とに左右に区画した自動販売機において、商品収納庫の背面全体を断熱する背面断熱板の中央部が外側に凸となるように反った場合においても、加温庫と冷却庫との間の熱移動を低減できる自動販売機を提供することを目的とする。 The present invention solves the above-mentioned conventional problems, and in a vending machine in which a product storage is partitioned into a heating chamber and a cooling chamber on the left and right by a heat insulating partition plate, the rear surface that insulates the entire rear surface of the product storage. An object of the present invention is to provide a vending machine capable of reducing the heat transfer between the heating chamber and the cooling chamber even when the central portion of the heat insulating plate is warped so as to protrude outward.

上記目的を達成するために、本発明の自動販売機は、前面を開口した商品収納庫の内壁面を少なくとも背面断熱板、側面断熱板で断熱し、さらに断熱仕切り板により前記商品収
納庫を加温庫と冷却庫とに左右に区画した自動販売機であって、前記加温庫の背面に位置する前記背面断熱板の前面に、左右の端面が前記側面断熱板と前記断熱仕切り板に弾性的に当接して、前記側面断熱板と前記断熱仕切り板に弾性的に挟持される加温庫背面断熱板を、前記背面断熱板が前記加温庫に露出しないように重ねたのである。 In order to achieve the above object, the vending machine of the present invention insulates the inner wall surface of the product storage with the front face open by at least a rear heat insulating plate and a side heat insulating plate, and further adds the product storage by a heat insulating partition plate. A vending machine that is divided into a left and right side of a warm chamber and a cooler, and the left and right end surfaces are elastic to the side heat insulating plate and the heat insulating partition plate on the front surface of the rear heat insulating plate located on the rear surface of the heating chamber. The heating insulator back heat insulating plate elastically sandwiched between the side heat insulating plate and the heat insulating partition plate is overlapped so that the back heat insulating plate is not exposed to the heating cabinet.

上記構成により、背面断熱板の中央部が外側に凸となるように反って、背面断熱板と断熱仕切り板との間の部分で断熱性が低下しても、加温庫背面断熱板が、背面断熱板と断熱仕切り板との間の断熱性が低下した部分と、加温庫との熱が伝わる通路を遮断しているので、加温庫内から冷却庫内への熱移動を抑えることができ、それにより自動販売機の消費電力量を低減することができる。 With the above configuration, even if the heat insulation is reduced in the portion between the back heat insulation plate and the heat insulation partition plate, the heating insulation back heat insulation plate is warped so that the center portion of the back heat insulation plate is convex outward. Since the heat conduction between the part with reduced heat insulation between the rear heat insulating plate and the heat insulating partition and the heating chamber is blocked, the heat transfer from the heating chamber to the cooling chamber should be suppressed. Thus, the power consumption of the vending machine can be reduced.

本発明によれば、背面断熱板の中央部が外側に凸となるように反って、背面断熱板と断熱仕切り板との間の部分で断熱性が低下しても、加温庫背面断熱板が、背面断熱板と断熱仕切り板との間の断熱性が低下した部分と、加温庫との熱が伝わる通路を遮断しているので、加温庫内から冷却庫内への熱移動を抑えることができ、それにより自動販売機の消費電力量を低減することができる。 According to the present invention, even if the heat insulation performance is lowered at the portion between the rear heat insulating plate and the heat insulating partition plate, the heating insulating rear heat insulating plate is warped so that the central portion of the rear heat insulating plate is convex outward. However, since the heat insulation between the part where the heat insulating property between the rear heat insulating plate and the heat insulating partition plate is lowered and the heat transfer to the heating chamber is blocked, the heat transfer from the heating chamber to the cooling chamber is prevented. The power consumption of the vending machine can be reduced.

Then, the entire ceiling surface of the inner wall surface of the space (product storage) on the upper side of the bottom heat insulating plate 2 is covered and insulated.

断熱仕切り板７は、加温庫となる左庫９と、冷却庫となる中庫１０とを仕切る断熱板であり、底面断熱板２と当接する下端面と背面断熱板３と当接する後端面と天面断熱板６と当接する上端面にポリエチレンフォームからなるクッション材１２を備えている。 The heat insulating partition plate 7 is a heat insulating plate that partitions the left chamber 9 serving as a heating chamber and the middle chamber 10 serving as a cooling chamber, and a rear end surface contacting the bottom heat insulating plate 2 and a rear heat insulating plate 3. A cushion material 12 made of polyethylene foam is provided on the upper end surface in contact with the top heat insulating plate 6.

断熱仕切り板８は、冷却庫となる中庫１０と、冷却庫となる右庫１１とを仕切る断熱板であり、底面断熱板２と当接する下端面と背面断熱板３と当接する後端面と天面断熱板６と当接する上端面にポリエチレンフォームからなるクッション材１２を備えている。 The heat insulating partition plate 8 is a heat insulating plate that partitions the middle store 10 serving as a refrigerator and the right store 11 serving as a refrigerator, and includes a lower end surface that contacts the bottom heat insulating plate 2 and a rear end surface that contacts the rear heat insulating plate 3. A cushion material 12 made of polyethylene foam is provided on the upper end surface in contact with the top heat insulating plate 6.

左庫９、中庫１０、右庫１１のそれぞれの背面側には、上端に空気吸い込み口、下部前面に空気吹き出し口が形成された背面ダクト１３，１４，１５が設けられる。 On the back side of each of the left warehouse 9, the middle warehouse 10, and the right warehouse 11, rear ducts 13, 14, and 15 having an air inlet at the upper end and an air outlet at the lower front are provided.

そして、庫内の下部において冷媒サイクルを構成する庫内熱交換器（図示せず）等により冷却または加熱された空気は、庫内循環用の送風機（図示せず）により、庫内に吹き出され、庫内の商品を冷却または加温した後、背面ダクト１３，１４，１５の上端の空気吸い込み口に吸い込まれ、背面ダクト１３，１４，１５の中を下降して、背面ダクト１３，１４，１５の下部前面の空気吹き出し口から庫内下部の庫内熱交換器（図示せず）等が配置された部分に戻る。 And the air cooled or heated by the internal heat exchanger (not shown) etc. which comprise a refrigerant cycle in the lower part in an inside of a warehouse is blown out in the inside by the air circulation fan (not shown). After the product in the cabinet is cooled or heated, it is sucked into the air suction port at the upper end of the rear ducts 13, 14, 15 and descends in the rear ducts 13, 14, 15 to return to the rear ducts 13, 14, 15 returns from the air outlet at the front of the lower part to the part where the internal heat exchanger (not shown) at the lower part of the internal part is disposed.

本実施の形態では、加温庫となる左庫９の背面に位置する背面断熱板３の前面に、左右の端面が左側面断熱板４と断熱仕切り板７に弾性的に当接して、左側面断熱板４と断熱仕切り板７に弾性的に挟持される加温庫背面断熱板１６を、背面断熱板３が左庫９に露出しないように重ねている。なお、加温庫背面断熱板１６は背面断熱板３と左庫９の背面ダクト１３との間に配置されることになる。 In the present embodiment, the left and right end surfaces elastically contact the left side heat insulating plate 4 and the heat insulating partition plate 7 on the front surface of the rear heat insulating plate 3 located on the rear surface of the left chamber 9 serving as a heating chamber, and the left side A heating chamber rear heat insulating plate 16 elastically sandwiched between the surface heat insulating plate 4 and the heat insulating partition plate 7 is stacked so that the rear heat insulating plate 3 is not exposed to the left chamber 9. In addition, the heating chamber rear heat insulating plate 16 is disposed between the rear heat insulating plate 3 and the rear duct 13 of the left chamber 9.

本実施の形態では、加温庫背面断熱板１６に、厚みが約１５ｍｍの発泡スチロール板を用いており、左庫９の背面ダクト１３の奥行き寸法は、加温庫背面断熱板１６を設けたことにより、中庫１０、右庫１１の背面ダクト１４，１５の奥行き寸法（約３０ｍｍ）よりも、約１５ｍｍ小さくなっており、背面ダクト１３の奥行き寸法が小さくなって背面ダクト１３の風路抵抗が増加したことを考慮して、左庫９の庫内循環用の送風機（図示せず）は加温庫背面断熱板１６を設けていないものと較べて回転数（送風量）を増やしている。 In the present embodiment, a foamed polystyrene plate having a thickness of about 15 mm is used for the heating chamber rear heat insulating plate 16, and the depth dimension of the rear duct 13 of the left chamber 9 is provided with the heating chamber rear heat insulating plate 16. Therefore, the depth dimension of the rear ducts 14 and 15 (about 30 mm) of the middle warehouse 10 and the right warehouse 11 is about 15 mm smaller, the depth dimension of the rear duct 13 becomes smaller, and the air duct resistance of the rear duct 13 is reduced. In consideration of the increase, the internal circulation fan (not shown) of the left warehouse 9 increases the rotational speed (air flow rate) compared to the case where the heating chamber rear heat insulating plate 16 is not provided.

加温庫背面断熱板１６の材料として、発泡ウレタンフォームや、真空断熱材も候補に挙がったが、発泡スチロールを採用した。その理由は、発泡スチロールの方が他の断熱材より弾力性と断熱板の生産効率に優れ、真空断熱材は高価で、コストアップとなるからである。 Although foamed urethane foam and vacuum heat insulating materials were cited as candidates for the material of the heating chamber back heat insulating plate 16, polystyrene foam was adopted. The reason is that the polystyrene foam is superior in elasticity and the production efficiency of the heat insulating plate than other heat insulating materials, and the vacuum heat insulating material is expensive and increases the cost.

加温庫背面断熱板１６を、左側面断熱板４と断熱仕切り板７とで、しっかりと保持するためには、加温庫背面断熱板１６の厚みを断熱仕切り板７の使用（設置）時のクッション材１２の厚みよりも厚くすることが望ましい。 In order to hold the heating chamber rear heat insulating plate 16 firmly between the left side heat insulating plate 4 and the heat insulating partition plate 7, the thickness of the heating chamber rear heat insulating plate 16 is set to the thickness of the heat insulating partition plate 7 during use (installation). It is desirable to make it thicker than the thickness of the cushion material 12.

以上のように本実施の形態の自動販売機は、前面を開口した商品収納庫の内壁面を少なくとも背面断熱板３、側面断熱板４，５で断熱し、さらに断熱仕切り板７により商品収納庫を加温庫（左庫９）と冷却庫（中庫１０）とに左右に区画した自動販売機であって、加温庫（左庫９）の背面に位置する背面断熱板３の前面に、左右の端面が左側面断熱板４と断熱仕切り板７に弾性的に当接して、左側面断熱板４と断熱仕切り板７に弾性的に挟持される加温庫背面断熱板１６を、背面断熱板３が加温庫（左庫９）に露出しないように重ねたことを特徴とする。 As described above, the vending machine according to the present embodiment insulates the inner wall surface of the product storage with the front opened by at least the rear heat insulating plate 3 and the side heat insulating plates 4 and 5, and further the product storage by the heat insulating partition plate 7. Is a vending machine that is divided into a heating chamber (left chamber 9) and a cooling chamber (middle chamber 10) on the left and right sides, on the front surface of the rear heat insulating plate 3 located on the back of the heating chamber (left chamber 9). The left and right end surfaces elastically contact the left side heat insulating plate 4 and the heat insulating partition plate 7, and the heating chamber rear heat insulating plate 16 elastically held between the left side heat insulating plate 4 and the heat insulating partition plate 7 The heat insulating plates 3 are stacked so as not to be exposed to the heating chamber (left chamber 9).

上記構成により、図３に示すように、背面断熱板３の中央部が外側に凸となるように反って、背面断熱板３と断熱仕切り板７との間の部分でクッション材１２の弾性復元力では
カバーできない隙間ができて、背面断熱板３と加温庫背面断熱板１６との間にできる空間が冷却庫（中庫１０）の空間と連通することにより、背面断熱板３と断熱仕切り板７との間の部分で断熱性が低下しても、加温庫背面断熱板１６が、背面断熱板３と断熱仕切り板７との間の断熱性が低下した部分（背面断熱板３と断熱仕切り板７との間と背面断熱板３と加温庫背面断熱板１６との間にでき、冷却庫（中庫１０）の空間と連通する空間）と、加温庫（左庫９）との熱が伝わる通路を遮断しているので、加温庫（左庫９）内から冷却庫（中庫１０）内への熱移動を抑えることができ、それにより自動販売機の消費電力量を低減することができる。 With the above configuration, as shown in FIG. 3, the central portion of the back heat insulating plate 3 is warped so as to protrude outward, and the cushion material 12 is elastically restored at the portion between the back heat insulating plate 3 and the heat insulating partition plate 7. A space that cannot be covered by force is formed, and a space formed between the rear heat insulating plate 3 and the heating chamber rear heat insulating plate 16 communicates with the space of the cooling chamber (the inner chamber 10), whereby the rear heat insulating plate 3 and the heat insulating partition. Even if the heat insulating property is reduced in the portion between the plate 7 and the heating chamber back heat insulating plate 16, the heat insulating property between the back heat insulating plate 3 and the heat insulating partition plate 7 is reduced (the back heat insulating plate 3 and The space between the heat insulating partition plate 7, the back heat insulating plate 3 and the heating chamber rear heat insulating plate 16, which communicates with the space of the cooling chamber (inside chamber 10), and the heating chamber (left chamber 9). Since the passage through which heat is transmitted is blocked, the heat transfer from the heating chamber (left chamber 9) to the cooling chamber (center chamber 10) Obtain it can, thereby reducing the power consumption of the vending machine.

本実施の形態において、実施の形態１と同一構成については同一符号を付して、その詳細な説明は省略する。 In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

本実施の形態は、加温庫背面断熱板１６の左端面に弾性変形部材としてクッション材１８を有する点で、実施の形態１と異なっており、その他の構成は実施の形態１と同様である。 The present embodiment is different from the first embodiment in that the cushioning member 18 is provided as an elastic deformation member on the left end surface of the heating chamber rear heat insulating plate 16, and the other configurations are the same as those of the first embodiment. .

クッション材１８の材料は、例えばウレタンフォームや独立発泡ポリエチレンフォームであり、加温庫背面断熱板１６の左端面の寸法に合わせたものを用いており、粘着面を加温庫背面断熱板１６の左端面に貼り付ける。両者の寸法が異なると取付け冶具が必要となり作業性が低下するが、両者の寸法を合わせれば冶具を用いずに所定の位置に取付けることができ作業性が向上するためである。 The material of the cushion material 18 is, for example, urethane foam or independent foamed polyethylene foam, and uses a material that matches the size of the left end face of the warming chamber rear heat insulating plate 16. Paste to the left edge. If the two dimensions are different, a mounting jig is required and workability is lowered. However, if both dimensions are matched, the jig can be mounted at a predetermined position without using the jig and workability is improved.

以上のように本実施の形態の自動販売機は、実施の形態１の構成において、左右の少なくともどちらか一方の端面に弾性変形部材（クッション材１８）を有する加温庫背面断熱板１６を用いるものであり、加温庫背面断熱板１６を構成する断熱材に比較的断熱性に優れるが弾性変形しにくい断熱材を用いた場合であっても、また、左側面断熱板４と断熱仕切り板７との間隔と加温庫背面断熱板１６の左右方向の寸法（幅寸法）の少なくともどちらか一方に設計寸法との誤差（製造寸法バラツキ）があっても、左右方向の端面部分を弾性変形部材（クッション材１８）で構成していれば、加温庫背面断熱板１６の左右の端面を左側面断熱板４と断熱仕切り板７に弾性的に当接させて、背面断熱板３の中央部が外側に凸となるように反った場合においても加温庫背面断熱板１６を左側面断熱板４と断熱仕切り板７とで保持することができる。 As described above, the vending machine according to the present embodiment uses the heating chamber rear heat insulating plate 16 having the elastic deformation member (cushion material 18) on at least one of the left and right end surfaces in the configuration of the first embodiment. Even when a heat insulating material that is relatively excellent in heat insulating properties but hardly elastically deforms is used for the heat insulating material constituting the heating chamber rear heat insulating plate 16, the left side heat insulating plate 4 and the heat insulating partition plate are also used. Even if there is an error (manufacturing size variation) from the design dimension in at least one of the space between the heater 7 and the horizontal dimension (width dimension) of the heating chamber rear heat insulating plate 16, the lateral end face part is elastically deformed. If it comprises a member (cushion material 18), the left and right end surfaces of the heating chamber rear heat insulating plate 16 are elastically brought into contact with the left side heat insulating plate 4 and the heat insulating partition plate 7, so that the center of the rear heat insulating plate 3 is When the part warps so that it protrudes outward There can also hold a warming cabinet rear heat insulator 16 at the left side insulation plate 4 and the heat insulating partition plate 7.

なお、図６に示すように、左端面ではなく右端面に弾性変形部材としてクッション材１８を有する加温庫背面断熱板１６や、左端面と右端面の両方に弾性変形部材としてクッション材１８を有する加温庫背面断熱板１６を用いても構わないが、その場合は、クッション材１８とクッション材１２とが接触するために、加温庫背面断熱板１６の左端面にクッション材１８を有する場合よりも、加温庫背面断熱板１６を左側面断熱板４と断熱仕切り板７とで保持する力は低下し、クッション材１８とクッション材１２とが熱（空気）の通り道になりやすいので、注意が必要である。 In addition, as shown in FIG. 6, the heating chamber back heat insulating plate 16 having the cushion material 18 as an elastic deformation member on the right end surface instead of the left end surface, or the cushion material 18 as an elastic deformation member on both the left end surface and the right end surface. However, in this case, since the cushion material 18 and the cushion material 12 are in contact with each other, the cushion material 18 is provided on the left end surface of the warming chamber back heat insulation plate 16. Since the force for holding the heating chamber rear heat insulating plate 16 with the left side heat insulating plate 4 and the heat insulating partition plate 7 is lower than the case, the cushion material 18 and the cushion material 12 are likely to become a passage for heat (air). ,Caution must be taken.

FIG. 7 is a schematic cross-sectional view of the main body excluding the door of the vending machine according to the third embodiment of the present invention, which is cut horizontally at the product storage portion.

本実施の形態は、加温庫背面断熱板１６は、背面断熱板３と対向する面に弾性変形部材としてクッション材１９を有する点で、実施の形態１と異なっており、その他の構成は実施の形態１と同様である。 The present embodiment is different from the first embodiment in that the heating chamber rear heat insulating plate 16 has a cushion material 19 as an elastic deformation member on the surface facing the rear heat insulating plate 3, and other configurations are implemented. This is the same as the first embodiment.

クッション材１８の材料は、例えばウレタンフォームや独立発泡ポリエチレンフォームであり、加温庫背面断熱板１６の背面の寸法に合わせたものを用いており、粘着面を加温庫背面断熱板１６の背面に貼り付ける。両者の寸法が異なると取付け冶具が必要となり作業性が低下するが、両者の寸法を合わせれば冶具を用いずに所定の位置に取付けることができ作業性が向上するためである。 The material of the cushion material 18 is, for example, urethane foam or polyethylene foam, and uses a material that matches the size of the back surface of the heating chamber back heat insulating plate 16. The adhesive surface is the back surface of the heating chamber back heat insulating plate 16. Paste to. If the two dimensions are different, a mounting jig is required and workability is lowered. However, if both dimensions are matched, the jig can be mounted at a predetermined position without using the jig and workability is improved.

以上のように本実施の形態の自動販売機は、実施の形態１の構成において、背面断熱板３と対向する面に弾性変形部材としてクッション材１９を有する加温庫背面断熱板１６を用いるものであり、図８に示すように、背面断熱板３の中央部が外側に凸となるように反った場合に、背面断熱板３と加温庫背面断熱板１６との間に隙間ができにくくなるので、また、背面断熱板３の前面と加温庫背面断熱板１６の背面の少なくともどちらか一方に凹凸があっても、背面断熱板３と加温庫背面断熱板１６との間に隙間ができにくくなるので、背面断熱板３と加温庫背面断熱板１６との隙間を経由した加温庫（左庫９）内から冷却庫（中庫１０）内への熱移動を抑えることができ、それにより、自動販売機の消費電力量を低減することができる。 As described above, the vending machine according to the present embodiment uses the heating chamber rear heat insulating plate 16 having the cushion material 19 as an elastic deformation member on the surface facing the rear heat insulating plate 3 in the configuration of the first embodiment. As shown in FIG. 8, when the central portion of the back heat insulating plate 3 is warped so as to protrude outward, a gap is not easily formed between the back heat insulating plate 3 and the heating chamber back heat insulating plate 16. Therefore, even if at least one of the front surface of the back heat insulating plate 3 and the back surface of the heating chamber back heat insulating plate 16 is uneven, there is a gap between the back heat insulating plate 3 and the heating chamber back heat insulating plate 16. Therefore, it is possible to suppress the heat transfer from the heating chamber (left chamber 9) to the cooling chamber (center chamber 10) through the gap between the rear heat insulating plate 3 and the heating chamber rear heat insulating plate 16. Thus, the power consumption of the vending machine can be reduced.

以上のように、本発明は、背面断熱板の中央部が外側に凸となるように反って、背面断熱板と断熱仕切り板との間の部分で断熱性が低下しても、加温庫背面断熱板が、背面断熱
板と断熱仕切り板との間の断熱性が低下した部分と、加温庫との熱が伝わる通路を遮断しているので、加温庫内から冷却庫内への熱移動を抑えることができ、それにより自動販売機の消費電力量を低減することができるので、加温販売する商品と冷却販売する商品とを隣接した庫内に収納して販売する飲料自動販売機に最適である。 As described above, the present invention warps so that the central portion of the rear heat insulating plate protrudes outward, and even if the heat insulating property is lowered at the portion between the rear heat insulating plate and the heat insulating partition plate, the heating chamber Since the back heat insulating plate blocks the part where the heat insulating property between the back heat insulating plate and the heat insulating partition plate is reduced and the passage through which heat is transmitted to the heating chamber, the inside of the heating chamber to the cooling chamber Since heat transfer can be suppressed, and the power consumption of the vending machine can be reduced, beverage vending that stores and sells products that are sold hot and products that are sold cold Ideal for machine.
