Description

本発明は、例えばファーストフードなどの各種店舗に設置され、中華まんなどの被展示物を展示する展示保管機に関するものである。   The present invention relates to an exhibition storage machine that is installed in various stores such as fast food and displays exhibits to be exhibited such as Chinese buns.

従来、ファーストフードなどにおける調理品の展示・販売においては、例えば特許文献1に開示されるように、蒸気制御弁を開閉制御しながら筐体内に蒸気を導入することで、棚に載置される食品の加熱や保温を行う蒸し器を利用した展示・販売形態が普及してきている。   Conventionally, in the display and sale of cooked foods in fast food and the like, for example, as disclosed in Patent Document 1, the steam control valve is opened and closed, and steam is introduced into the housing while being placed on the shelf. Display and sales forms using steamers that heat and heat food are becoming popular.

この種の展示保管機としての蒸し器のショウケースは、図10にその外観図を示すように、一乃至複数段の棚201を筐体202の内部に備えると共に、この筐体202の外郭をなす部材(外郭部材)を、透明部材であるガラス203で形成している。棚201には、図示しない食材などの被展示物が陳列される。またこの図では、外郭部材の前面と両側面を形成するガラス203が、枠状部材204によって支持されているが、一般的には顧客に対する食材の見易さなどを考慮して、この外郭部材の前面と両側面を一体ガラスで構成したものが主流である。さらに、使用するガラス203は断熱性を高めるために、複層透明部材である複層(二重)ガラスとするのが主流である。   The steamer showcase as this type of exhibition storage machine has one or more shelves 201 inside the casing 202 as shown in FIG. The member (outer member) is formed of glass 203 which is a transparent member. On the shelf 201, objects to be displayed such as ingredients (not shown) are displayed. In this figure, the glass 203 forming the front surface and both side surfaces of the outer member is supported by the frame-like member 204. The mainstream is that the front and both sides are made of monolithic glass. Furthermore, in order to improve the heat insulation, the glass 203 to be used is mainly a multi-layer (double) glass which is a multi-layer transparent member.

ガラス203として複層ガラスを用いた場合、内外のガラス面を一定の間隔をもって一体化する必要があることから、複層ガラスの端部にはスペーサのような保持部材が必要になる。また、筐体202の下部には蒸気発生装置(図示せず)が設けられていることから、複層ガラスを構成する外側ガラスには、複層ガラス内部の空気を対流させ、外面のガラス温度を低下させるための穴が、複層ガラスの概ね上下端部近傍に設けられている。   When a double-layer glass is used as the glass 203, it is necessary to integrate the inner and outer glass surfaces at regular intervals, and thus a holding member such as a spacer is required at the end of the multi-layer glass. In addition, since a steam generator (not shown) is provided at the lower part of the housing 202, air inside the multilayer glass is convected to the outer glass constituting the multilayer glass, and the glass temperature of the outer surface is determined. Is provided in the vicinity of the upper and lower end portions of the multilayer glass.

一方、このような蒸し器は、中華まんなどの商品を展示販売する筐体の下部中央に、蒸発容器や加熱手段を備えた蒸気発生装置が設けられており、蒸気発生装置の周囲には底部で連通開口したタンクすなわち水タンクが配置されている。そして、水タンクからの水を有底状の蒸発容器に導き、この蒸発容器を加熱手段で加熱することで、気化容器用蓋の穴を通して蒸気が筐体の内部に噴出し、陳列された食材を蒸すようになっている。
特開平9−98889号公報
On the other hand, such a steamer is provided with a steam generator equipped with an evaporation container and a heating means at the lower center of a casing for displaying and selling products such as Chinese buns, and communicated at the bottom around the steam generator. An open tank or water tank is arranged. And the water from the water tank is led to the bottomed evaporation container, and the evaporation container is heated by the heating means, so that the steam is jetted into the inside of the casing through the hole of the vaporization container lid, and the displayed foodstuff Is supposed to steam.
Japanese Patent Laid-Open No. 9-99889

図に示すような複層ガラスにより筐体202の外面を構成した蒸し器は、ガラス203からの放熱を極力少なくして省エネを図ることに考慮されてはいるが、ガラス203からの放熱は、外側ガラスや内側ガラスの厚さや、外側および内側ガラス間の空気層の厚さで決まってしまい、筐体202内部の熱を外部に逃がさないようにする省エネとしての効果は、自ずと限度があった。とりわけ、コンビニエンスストア(CVS)などで中華まん販売機として設置される蒸し器は、昼夜を問わず一日中運転する場合が多く、複層ガラスを通しての熱の逃げは大きな課題であった。   Although the steamer in which the outer surface of the housing 202 is composed of the multilayer glass as shown in the figure is considered to save energy by minimizing the heat radiation from the glass 203, the heat radiation from the glass 203 is outside. The effect of energy saving that prevents the heat inside the housing 202 from escaping to the outside, which is determined by the thickness of the glass and the inner glass and the thickness of the air layer between the outer and inner glasses, is naturally limited. In particular, the steamer installed as a Chinese bun vending machine at a convenience store (CVS) or the like is often operated all day or night, and the escape of heat through the multi-layer glass has been a major issue.

また、蒸気発生装置に代わり、筐体内の被展示物を冷却する冷却装置を備えた保管機能を有する展示保管機にあっては、筺体をなすショーケース内の冷気が複層ガラスを通して外気により温められてしまうので、外部からの熱の侵入をいかに抑制するかという課題があった。   In addition, in an exhibition storage machine having a storage function provided with a cooling device for cooling the exhibits in the housing instead of the steam generator, the cool air in the showcase forming the enclosure is warmed by the outside air through the multilayer glass. Therefore, there is a problem of how to suppress the intrusion of heat from the outside.

さらに、筐体の外面一側には商品を出し入れするための開口部が設けられていて、この開口部を塞ぐための扉が開閉可能に設けられている。特に展示保管機の扉は、筐体の内部を見やすくするためと、ショーケース的な要素から、周囲の枠を除く略全面をガラスなどの透明部材で構成するのが一般的であった。しかし、ここでも透明部材を通しての熱の逃げにより、筐体内部の熱が外部に放散しているのが実態であった。   Furthermore, an opening for taking in and out the product is provided on one side of the outer surface of the housing, and a door for closing the opening is provided to be openable and closable. In particular, the doors of exhibition storage machines are generally made up of a transparent member such as glass, so that the inside of the housing is easy to see and because of the showcase-like elements, almost the entire surface excluding the surrounding frame. However, in this case as well, the actual condition is that the heat inside the casing is dissipated to the outside due to the escape of heat through the transparent member.

以下、本発明における展示保管機の各実施例について、図面を参照しながら説明する。   Hereinafter, each example of an exhibition storage machine according to the present invention will be described with reference to the drawings.

図1〜図6は本発明の第1実施例を示すもので、ここでは展示保管機としての蒸し器の構成について説明する。全体構成を示す図1および図2において、1は略直方体に形成される筐体で、この筐体1の下部開口部には、筐体1内に加熱装置となる蒸気発生装置2を内部に備えた基台3が設けられている。基台3は、その側面外郭をなす枠状の台座4と、中央部を残して台座4の上面開口部を覆うように設けた取付座5などにより構成される。7は、ショーケースの外面に相当するガラスで、これは筐体1の前面と上面の2面を形成し、側面から見て略への字状に折り曲げ形成された複層透明部材からなる前面ガラス8と、筐体1の一側面と他側面をそれぞれ形成し、前面ガラス8の端面に略密封して取付け固定される同じく複層透明部材からなる一対の側面ガラス9とにより構成され、これらの前面ガラス8と側面ガラス9は共に取付座5に載るように設けられている。こうして、食材などのひ展示物を陳列する筐体1は、その側面部を形成する周囲の少なくとも一方向を複層透明部材であるガラス7で覆っている。   FIGS. 1-6 shows the 1st Example of this invention, and demonstrates the structure of the steamer as an exhibition storage machine here. In FIG. 1 and FIG. 2 showing the entire configuration, reference numeral 1 denotes a casing formed in a substantially rectangular parallelepiped, and a steam generator 2 serving as a heating device is provided inside the casing 1 in a lower opening of the casing 1. A provided base 3 is provided. The base 3 includes a frame-shaped base 4 that forms a side surface of the base 3 and a mounting base 5 that is provided so as to cover the upper surface opening of the base 4 while leaving the center. 7 is a glass corresponding to the outer surface of the showcase, which forms two surfaces, a front surface and an upper surface of the housing 1, and is a front surface made of a multi-layer transparent member that is bent into a generally U shape when viewed from the side surface. The glass 8 is composed of a pair of side glass 9 that is formed of one side surface and the other side surface of the housing 1 and is substantially hermetically sealed and attached to the end surface of the front glass 8. The front glass 8 and the side glass 9 are both provided on the mounting seat 5. In this way, the casing 1 displaying the display such as foods covers at least one direction of the periphery forming the side surface with the glass 7 which is a multilayer transparent member.

ガラス7が設けられていない筐体1の後面側には、非透明部材である枠状部材10が設けられ、この枠状部材10により商品を出し入れする開口部が形成される。そして、枠状部材10の開口部を密閉状態に覆うべく、周囲にパッキン(図示せず)を備えた扉11が回動かつ開閉自在に設けられている。また、扉11を通して筐体1の内部が視認できるように、扉11はその周囲にある枠体12を除く部分に透明部材であるガラス13が設けられる。なお、14は扉11の開閉を容易にするための取手である。   A frame-like member 10 which is a non-transparent member is provided on the rear surface side of the casing 1 where the glass 7 is not provided, and an opening for taking in and out a product is formed by the frame-like member 10. In order to cover the opening of the frame-like member 10 in a sealed state, a door 11 provided with a packing (not shown) around it is provided so as to be rotatable and openable. The door 11 is provided with a glass 13 which is a transparent member in a portion excluding the frame body 12 around the door 11 so that the inside of the housing 1 can be visually recognized through the door 11. Reference numeral 14 denotes a handle for facilitating opening and closing of the door 11.

筐体1の下部にある基台3は有底筒状で、ここには前述のように筐体1内に蒸気を送り出す蒸気発生装置2が設けられる。また、筐体1の内部には、上下複数段に商品を陳列するための棚15が設けられる。棚15は、筐体1の両側部内面に設けられた左右一対のレール(図示せず)に着脱可能で、かつスライド移動可能に配置される。そして、基台3の後方に設けられた操作パネル16の操作ボタン(図示せず)を押して、蒸し器機能を選択すると、蒸気発生装置2から水を加熱蒸発させる。これによって、棚15に載置される例えば中華まんなどの蒸し器に適した食材を、良好な状態に保管できる。   The base 3 at the bottom of the housing 1 has a bottomed cylindrical shape, and is provided with a steam generator 2 for sending steam into the housing 1 as described above. Further, a shelf 15 for displaying products in a plurality of upper and lower stages is provided inside the housing 1. The shelf 15 is detachably mounted on a pair of left and right rails (not shown) provided on the inner surfaces of both sides of the housing 1 and is slidable. And if the operation button (not shown) of the operation panel 16 provided in the back of the base 3 is pushed and a steamer function is selected, water will be heated and evaporated from the steam generator 2. FIG. As a result, food suitable for a steamer such as a Chinese bun placed on the shelf 15 can be stored in good condition.

次に、枠状部材10や扉11と共に筐体1の外郭部材をなすガラス7の詳細な構成を図3〜図6に基づき説明する。本実施例におけるガラス7は、筐体1の内部に面した内ガラス21と、筐体1の外部に面した外ガラス22とにより構成され、これらの内ガラス21と外ガラス22を隙間を有した状態で保持する間隔保持部材23が、内ガラス21と外ガラス22との間の全周端面近傍に配置される。なお、ガラス7を複層透明部材とする理由は、筐体1の外面に手などを触れた場合に火傷しないようにするためである。間隔保持部材23には、ガラス7の組立て時にガラス7の上方に位置して、内ガラス21および外ガラス22と略平行に2個の穴すなわち換気穴24が設けられる。こうして、2枚の内ガラス21,外ガラス22および間隔保持部材23で形成された閉空間とガラス7の外部との間を、換気穴24により連通開口している。さらに、間隔保持部材23の外周に位置する内ガラス21と外ガラス22との間には、換気穴24を設けた部分を除きほぼ全周端面に渡って接着剤25が封印固定される。   Next, a detailed configuration of the glass 7 that forms the outer member of the housing 1 together with the frame-shaped member 10 and the door 11 will be described with reference to FIGS. The glass 7 in this embodiment is composed of an inner glass 21 facing the inside of the housing 1 and an outer glass 22 facing the outside of the housing 1, and the inner glass 21 and the outer glass 22 have a gap. A spacing member 23 that is held in this state is disposed in the vicinity of the entire peripheral end surface between the inner glass 21 and the outer glass 22. The reason why the glass 7 is a multi-layer transparent member is to prevent burns when touching the outer surface of the housing 1 with a hand or the like. The spacing member 23 is provided with two holes, that is, ventilation holes 24, which are positioned above the glass 7 when the glass 7 is assembled and are substantially parallel to the inner glass 21 and the outer glass 22. In this way, the ventilation space 24 opens the closed space formed by the two inner glasses 21, the outer glass 22 and the spacing member 23 and the outside of the glass 7. Further, between the inner glass 21 and the outer glass 22 positioned on the outer periphery of the spacing member 23, the adhesive 25 is sealed and fixed over almost the entire peripheral end surface except for the portion provided with the ventilation holes 24.

なお、本実施例における換気穴24は、例えばガラス7の対角位置にそれぞれ設けるなどして、間隔保持部材23のどの位置に設けられていてもよく、また個数も1個または2個に限定されない。特に換気穴24を2個設けると、ガラス7内部の対流でガラス7の温度が必要以上に下がり、蒸気発生装置2を構成する加湿ヒーターの消費電力が増加する場合には、ガラス7内部の対流を少なくするために、本実施例のように換気穴24を1個だけにしてもよい。こうすれば、筐体1内部を保温温度に維持する加湿ヒーターの消費電力を減らすことができる。   Note that the ventilation holes 24 in this embodiment may be provided at any position of the spacing member 23 by, for example, providing them at diagonal positions of the glass 7, and the number is limited to one or two. Not. In particular, when two ventilation holes 24 are provided, the convection inside the glass 7 is caused when the temperature of the glass 7 falls more than necessary due to the convection inside the glass 7 and the power consumption of the humidifying heater constituting the steam generating device 2 increases. In order to reduce this, only one ventilation hole 24 may be provided as in this embodiment. If it carries out like this, the power consumption of the humidification heater which maintains the inside of the housing | casing 1 at heat retention temperature can be reduced.

ガラス7の端面周囲は、内ガラス21および外ガラス22の熱膨張を吸収するための弾性に富むガラスパッキン27が覆っている。また、このガラスパッキン27の外面を覆うように、ガラス7の端面周囲にはガラス枠が設けられており、外部の構造物(図示せず)と接合されている。ガラス7の周囲に設けられる枠部材としてのガラスパッキン27およびガラス枠28には、換気穴24に対応してこの換気穴24を塞がないように図示しない連通穴が設けられており、これらの換気穴24と連通穴とにより、ガラス7の内部と庫外である筐体1の外部とを連通させている。   A glass packing 27 rich in elasticity for absorbing thermal expansion of the inner glass 21 and the outer glass 22 is covered around the end face of the glass 7. Further, a glass frame is provided around the end surface of the glass 7 so as to cover the outer surface of the glass packing 27, and is joined to an external structure (not shown). The glass packing 27 and the glass frame 28 as frame members provided around the glass 7 are provided with communication holes (not shown) corresponding to the ventilation holes 24 so as not to block the ventilation holes 24. The ventilation hole 24 and the communication hole allow the inside of the glass 7 to communicate with the outside of the housing 1 that is outside the warehouse.

前記側面ガラス9を構成する内ガラス21と外ガラス22の隙間には、真空断熱材26が設けられている。この真空断熱材26は、図示しないが、芯材となるグラスウールと、このグラスウールを真空状態で包装する外装体とにより構成される。ここで使用される真空断熱材26は、内ガラス21および外ガラス22の層間内面全体に設けてもよいが、図6に示すように層内内面の一部にのみ部分的に設けてもよい。こうすると、真空断熱材26を必要に応じて層間内面の一部にだけ設けることになるので、真空断熱材26の材料費に関わるコストアップを抑制することができる。また、真空断熱材26そのものは不透明性のため、棚15に陳列した商品を見せるガラス7のウインド部分に真空断熱材26を設けると、ガラス7を通しての視認性が阻害されるが、例えば側面ガラス9の後方部など、蒸し器としての外観構成上、透明性を必要としない非ウインド部分に真空断熱材26を設けるならば、視認性はさほど低下しない。しかも、複層透明部材であるガラス7自体にもある程度の断熱性があるため、筐体1内部の商品を見やすくするためにウインド部の領域を多くしても、効果的に省エネを図ることができる。   A vacuum heat insulating material 26 is provided in the gap between the inner glass 21 and the outer glass 22 constituting the side glass 9. Although not shown, the vacuum heat insulating material 26 is composed of glass wool as a core material and an exterior body that wraps the glass wool in a vacuum state. The vacuum heat insulating material 26 used here may be provided on the entire inner surface of the inner glass 21 and the outer glass 22, but may be partially provided only on a part of the inner surface of the layer as shown in FIG. . In this case, the vacuum heat insulating material 26 is provided only on a part of the inner surface of the interlayer as necessary, so that an increase in cost related to the material cost of the vacuum heat insulating material 26 can be suppressed. Further, since the vacuum heat insulating material 26 itself is opaque, if the vacuum heat insulating material 26 is provided in the window portion of the glass 7 showing the product displayed on the shelf 15, the visibility through the glass 7 is hindered. If the vacuum heat insulating material 26 is provided in a non-window portion that does not require transparency in terms of the appearance configuration as a steamer, such as the rear portion of 9, the visibility does not deteriorate so much. Moreover, since the glass 7 itself, which is a multi-layer transparent member, also has a certain degree of heat insulation, even if the area of the window portion is increased in order to make the product inside the housing 1 easier to see, energy can be effectively saved. it can.

尚、本実施例では側面ガラス9が一体的に構成されたものを示したが、前記側面ガラス9は前後方向に2分割して構成されてもよい。例えば、図7に示すように、側面ガラス9のうち前方には真空断熱材26が介在しない複層の透明部材9aを配置し、後方には真空断熱材26を設けた複層の透明部材9bを配置し、各透明部材9a,9bどうしを接合して側面ガラス9を構成してもよい。このように構成することで、筐体1内部から側面ガラス9を通過して外部へ移動する熱量を分割することができるので、熱の移動を効果的に遮断できる。一方で、このような側面ガラス9においては、外観に凹凸が生じデザインの選択を狭めることになるが、断熱性に重点を置く製品開発において好ましい。   In the present embodiment, the side glass 9 is integrally formed, but the side glass 9 may be divided into two in the front-rear direction. For example, as shown in FIG. 7, a multi-layer transparent member 9 a in which a vacuum heat insulating material 26 is not interposed is arranged in front of the side glass 9, and a multi-layer transparent member 9 b in which a vacuum heat insulating material 26 is provided in the rear. The side glass 9 may be formed by arranging the transparent members 9a and 9b. By comprising in this way, since the calorie | heat amount which passes the side glass 9 from the inside of the housing | casing 1 and moves outside can be divided | segmented, the movement of heat can be interrupted | blocked effectively. On the other hand, such a side glass 9 is uneven in appearance and narrows the choice of design, but it is preferable in product development focusing on heat insulation.

さらに、前記真空断熱材26は、製造を容易にできるように改良したものとして、例えば、前記芯材をシート材としてのインナーパック(図示せず)内に収納し、外装体としてのバリア材によりこれらの芯材およびインナーパックを真空状態で包装して構成したものを用いてもよい。この真空断熱材26は平板状に形成されたものが好ましく用いられる。また、バリア材は、ガスバリア性を有し、かつ芯材およびインナーパックを収納して内部を真空に維持できると共に、蒸し器としての使用における耐熱性を備えている必要がある。この場合、バリア材はアルミニウムなどの金属により構成されるのが好ましい。また、コスト面を考慮して、真空断熱材26を内ガラス21と外ガラス22の隙間全体ではなく、図6に示すように、必要な一部分にのみ設けてもよい。   Further, the vacuum heat insulating material 26 has been improved so that it can be easily manufactured. For example, the core material is housed in an inner pack (not shown) as a sheet material, and a barrier material as an exterior body is used. You may use what comprised these core materials and inner packs by packaging in a vacuum state. The vacuum heat insulating material 26 is preferably formed in a flat plate shape. In addition, the barrier material needs to have a gas barrier property, and can hold the core material and the inner pack to keep the inside vacuum, and has heat resistance when used as a steamer. In this case, the barrier material is preferably composed of a metal such as aluminum. In view of cost, the vacuum heat insulating material 26 may be provided not only in the entire gap between the inner glass 21 and the outer glass 22, but only in a necessary portion as shown in FIG.

次に上記構成についてその作用を説明すると、蒸気発生装置2の加湿ヒーターを通電して筐体1内部の温度が上昇すると、筐体1の内面をなす内ガラス21が温度上昇し、ガラス7の閉空間における内部空気の温度および圧力が上昇する。この上昇した圧力に応じて、開口した換気孔24からガラス間の空気が逃げ、ガラス7の閉空間は減圧すると共に、ガラス7内部の温まった空気が排出される。   Next, the operation of the above structure will be described. When the humidifier heater of the steam generator 2 is energized and the temperature inside the housing 1 rises, the inner glass 21 forming the inner surface of the housing 1 rises in temperature. The temperature and pressure of the internal air in the closed space increase. In response to this increased pressure, the air between the glasses escapes from the open ventilation hole 24, the closed space of the glass 7 is decompressed, and the warm air inside the glass 7 is discharged.

さらに、筐体1内部からの熱は、内ガラス21の筐体1内部に面した側から伝導し、内ガラス21の内部を伝って、内ガラス21と外ガラス22の間の閉空間に放散しようとする。しかし、内ガラス21の閉空間には真空断熱材26が設けられているので、熱の大部分は移動が遮られ、ガラス7を複層透明部材で構成したことと相俟って、筐体1の外面となる外ガラス22の温度上昇を効果的に防止できる。なお、真空断熱材26によって吸収された熱は、真空断熱材26を通過し、外ガラス22に伝わる。そして、外ガラス22の内部から外表面に達したわずかな熱だけが、室内などの外部に放散することとなる。この真空断熱材26を設けたことにより、外ガラス22の表面温度は、真空断熱材26を設けていない従来のものに比べて約20℃低下し、誤って外ガラス22の表面に手などを触れたときの安全性を高めることができる。また、蒸気発生装置2の電力消費量も、従来のものに比べて70%に低減され、この点で省エネを図ることができる。   Further, heat from the inside of the housing 1 is conducted from the side of the inner glass 21 facing the inside of the housing 1, and is transmitted to the closed space between the inner glass 21 and the outer glass 22 through the inside of the inner glass 21. try to. However, since the vacuum heat insulating material 26 is provided in the closed space of the inner glass 21, the movement of most of the heat is blocked, and in combination with the fact that the glass 7 is composed of a multilayer transparent member, the housing The temperature rise of the outer glass 22 which becomes the outer surface of 1 can be effectively prevented. The heat absorbed by the vacuum heat insulating material 26 passes through the vacuum heat insulating material 26 and is transmitted to the outer glass 22. Only a slight heat reaching the outer surface from the inside of the outer glass 22 is dissipated to the outside such as the room. By providing this vacuum heat insulating material 26, the surface temperature of the outer glass 22 is reduced by about 20 ° C. compared to the conventional one not provided with the vacuum heat insulating material 26. Safety when touched can be increased. Moreover, the power consumption of the steam generator 2 is also reduced to 70% compared to the conventional one, and energy can be saved in this respect.

以上のように本実施例では、被展示物である商品を展示する筐体1に真空断熱材26を備えている。このようにすると、筐体1内部の熱が筺体1を通過しようとする際に、真空断熱材26により遮断されるため、筐体1の表面からの熱の逃げを防いで、省エネ効果を高めることができる。   As described above, in the present embodiment, the vacuum heat insulating material 26 is provided in the casing 1 that displays the products that are the exhibits. If it does in this way, when the heat inside the housing | casing 1 tries to pass the housing | casing 1, since it will be interrupted | blocked by the vacuum heat insulating material 26, the escape of the heat | fever from the surface of the housing | casing 1 will be prevented and the energy-saving effect will be improved. be able to.

また本実施例では、筺体1が複層透明部材であるガラス7からなり、このガラス7の間に真空断熱材26を設けている。この場合、真空断熱材26は複層透明部材であるガラス7の層間内面に設けられているので、日常の清掃などで真空断熱材26が傷付くなどの弊害もなく、長期にわたりその性能を維持できるとともに、筺体1の外部に凹凸がなく、筺体1表面における清掃性の低下を免れることができる。   In this embodiment, the housing 1 is made of glass 7 which is a multilayer transparent member, and a vacuum heat insulating material 26 is provided between the glasses 7. In this case, since the vacuum heat insulating material 26 is provided on the inner surface of the glass 7 which is a multi-layer transparent member, the vacuum heat insulating material 26 is not damaged by daily cleaning and the performance is maintained for a long time. In addition, there is no unevenness on the outside of the housing 1 and it is possible to avoid the deterioration of the cleaning property on the surface of the housing 1.

また本実施例では、筐体1の例えば下部にこの筺体1内を加湿する蒸気発生装置2を備えている。こうすると、蒸気発生装置2によって筺体2内にある中華まんなどの商品を加湿することができるが、こうした加湿機能を備えたいわゆる蒸し器に対しても、筐体1の表面からの熱の逃げを真空断熱材26により防いで、効果的に省エネ効果を高めることができる。   In this embodiment, a steam generator 2 for humidifying the inside of the housing 1 is provided, for example, at the lower part of the housing 1. In this way, products such as Chinese buns in the housing 2 can be humidified by the steam generating device 2, but the heat escape from the surface of the housing 1 is vacuumed against a so-called steamer having such a humidifying function. It can be prevented by the heat insulating material 26, and the energy saving effect can be enhanced effectively.

次に、本発明の第2実施例を図8に基づき説明する。なお、上記第1実施例と同一部分には同一符号を付し、その共通する箇所の説明は重複するため極力省略する。   Next, a second embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the same part as the said 1st Example, and since the description of the common location overlaps, it abbreviate | omits as much as possible.

本実施例は扉11の構造に関するもので、扉11以外の構成は第1実施例と全く共通している。図8は扉11の構成を示す分解斜視図であり、透明部材としてのガラス13の周囲にある枠体12は、扉11の外側に面した扉外枠29と、扉11の内側に面した扉内枠30と、枠状部材10に扉を回動および開閉自在に軸支する支軸部32と、前記扉11の開閉を容易に行なうための取手14とにより構成され、ガラス13は扉外枠29と扉内枠30に挟まれるようにして扉11の中央部に保持され、扉外枠29と扉内枠30とは止着部材であるボルト31によって一体化される。ガラス13は扉11と同様に縦長の長方形形状をなし、その短手方向(横方向)の長さは、扉11の横幅に一致する扉外枠29の横幅Wに比べて1/3程度の寸法に形成される。一方、ガラス13の長手方向は、扉11の縦幅に一致する扉外枠29の縦幅よりも多少短い程度で、少なくとも筐体1内部において上下多段に配置される棚15の全体が見通せる寸法に形成される。   This embodiment relates to the structure of the door 11, and the configuration other than the door 11 is completely the same as that of the first embodiment. FIG. 8 is an exploded perspective view showing the structure of the door 11, and the frame 12 around the glass 13 as a transparent member faces the door outer frame 29 facing the outside of the door 11 and the inside of the door 11. A door inner frame 30, a support shaft portion 32 that pivotally supports the frame-like member 10 so that the door can be rotated and opened and closed, and a handle 14 for easily opening and closing the door 11, and the glass 13 is a door. It is held at the center of the door 11 so as to be sandwiched between the outer frame 29 and the door inner frame 30, and the door outer frame 29 and the door inner frame 30 are integrated by a bolt 31 which is a fastening member. The glass 13 has a vertically long rectangular shape similar to the door 11, and the length in the short direction (lateral direction) is about 1/3 of the lateral width W of the door outer frame 29 that matches the lateral width of the door 11. Formed into dimensions. On the other hand, the longitudinal direction of the glass 13 is slightly shorter than the vertical width of the door outer frame 29 that coincides with the vertical width of the door 11, and at least the dimensions of the entire shelf 15 that is arranged in multiple upper and lower stages inside the housing 1 can be seen. Formed.

扉11の内部には、ガラス13を設けていない周囲空間に、真空断熱材26が設けられる。この真空断熱材26は、筐体1内部からの熱の逃げを防止し、本実施例ではガラス13の左右に位置して、扉外枠29と扉内枠30とにより真空断熱材26が挟持固定され、外部からは一切見えないようになっている。また、図中省略しているが、扉11のガラス13は第1実施例のような内ガラス21と外ガラス22を間隔保持部材23で保持した複層透明部材で構成するのが好ましい。   Inside the door 11, a vacuum heat insulating material 26 is provided in a surrounding space where the glass 13 is not provided. This vacuum heat insulating material 26 prevents the escape of heat from the inside of the housing 1, and is positioned on the left and right sides of the glass 13 in this embodiment, and the vacuum heat insulating material 26 is sandwiched between the door outer frame 29 and the door inner frame 30. It is fixed and cannot be seen from outside. Although not shown in the figure, the glass 13 of the door 11 is preferably composed of a multilayer transparent member in which an inner glass 21 and an outer glass 22 are held by a spacing member 23 as in the first embodiment.

しかして、本実施例では蒸気発生装置2の加湿ヒーターを通電して筐体1内部の温度が上昇すると、扉11のガラス13は内ガラス21から外ガラス22に熱伝導し、蒸し器の外部にある室内に放散する。しかし、扉11のガラス13は前述のようにその横幅が狭められており、外部への熱放散は極力最小限に抑えられている。一方、ガラス13の左右に位置して、扉11の内部には真空断熱材26が介在しているので、扉11の枠体12を通過しようとする熱の大部分は真空断熱材26により遮断され、わずかな熱が扉外枠29から外部に放散される。本実施例によれば、扉11のガラス13と扉外枠29との温度差は、実験の結果として扉外枠29がガラス13の外面よりも約20℃低くなった。また、製品全体として蒸気発生装置2の消費電力も従来のものに比べて70%に低減され、この点で省エネを図ることができる。   Thus, in this embodiment, when the humidifying heater of the steam generating device 2 is energized and the temperature inside the housing 1 rises, the glass 13 of the door 11 conducts heat from the inner glass 21 to the outer glass 22 and goes outside the steamer. Disperse into a room. However, the glass 13 of the door 11 has a narrow width as described above, and heat dissipation to the outside is minimized as much as possible. On the other hand, since the vacuum heat insulating material 26 is interposed inside the door 11 located on the left and right sides of the glass 13, most of the heat passing through the frame 12 of the door 11 is blocked by the vacuum heat insulating material 26. A small amount of heat is dissipated from the door outer frame 29 to the outside. According to the present example, the temperature difference between the glass 13 of the door 11 and the door outer frame 29 was about 20 ° C. lower than the outer surface of the glass 13 in the door outer frame 29 as a result of the experiment. Moreover, the power consumption of the steam generator 2 as a whole product is reduced to 70% compared to the conventional product, and energy saving can be achieved in this respect.

また、扉11のガラス13は扉11の縦幅と略同じ縦長形状に形成されているので、その横幅が扉11の横幅の半分以下程度であっても、商品を陳列する網状の棚15が多段に配置された筐体1の内部を、全体的に見通すことができる。すなわち、筐体1内部に配置された棚15が上下に配置されている関係で、販売員は筐体1内部の状況を、扉11のガラス13を通して支障なく確認することができる。   Further, since the glass 13 of the door 11 is formed in a vertically long shape substantially the same as the vertical width of the door 11, even if the horizontal width is about half or less of the horizontal width of the door 11, a net-like shelf 15 for displaying products is provided. The inside of the housings 1 arranged in multiple stages can be seen as a whole. That is, the salesperson can check the situation inside the casing 1 through the glass 13 of the door 11 without any trouble because the shelves 15 arranged inside the casing 1 are arranged vertically.

以上のように本実施例では、被展示物である商品を展示する筐体1に真空断熱材26を備えた展示保管機において、特に透明部材であるガラス13を有する扉11を筐体1に設け、ガラス13を除く扉11の例えば枠材12に真空断熱材26を配置している。   As described above, in the present embodiment, in the display storage machine provided with the vacuum heat insulating material 26 in the case 1 for displaying the product as the exhibit, the door 11 having the glass 13 as the transparent member is provided in the case 1. The vacuum heat insulating material 26 is disposed on the frame material 12 of the door 11 excluding the glass 13, for example.

こうすると、扉11のガラス13を除く部分では、真空断熱材26により筐体1内部の熱が遮断されるため、扉11からの熱の逃げを部分的に防いで、省エネ効果を高めることができる。また、顧客側から見えない側にある扉11により省エネを実施しているので、ショーケースとして最も重要な被展示物の見易さを損なわない利点があり、展示に関するデメリットなく省エネを実現できる。   In this way, the heat inside the housing 1 is cut off by the vacuum heat insulating material 26 in the portion other than the glass 13 of the door 11, so that the heat escape from the door 11 is partially prevented to increase the energy saving effect. it can. Further, since the energy is saved by the door 11 on the side that cannot be seen from the customer side, there is an advantage that the visibility of the most important exhibits as a showcase is not impaired, and the energy saving can be realized without the disadvantages related to the exhibition.

また本実施例では、ガラス13は縦長形状で、扉11の半分以下の横幅に形成されている。すなわち、ガラス13が縦長形状を有しているため、ガラス13が扉11の半分以下の横幅に形成されていても、筐体1の内部に商品が上下多段に陳列されている場合に、扉11側にいる販売員が筐体1の内部にある商品を不自由なく容易に確認できる。さらに重量のある透明部材を小さくすることで、扉11の軽量化を図って操作性を高めることができる。   In this embodiment, the glass 13 is vertically long and has a width that is less than half that of the door 11. That is, since the glass 13 has a vertically long shape, even if the glass 13 is formed to have a width that is less than half that of the door 11, the door is used when the product is displayed in multiple stages in the housing 1. The salesperson on the 11th side can easily check the products in the housing 1 without inconvenience. Further, by reducing the weight of the transparent member, the door 11 can be lightened and the operability can be improved.

尚、上記した第1および第2実施例では蒸し器としてのショーケースについて説明したが、保冷装置としてのショーケースにおいても同様に実施可能である。すなわち、この場合の保冷装置は、蒸気発生装置2に換わって冷却装置33(図1参照)が基台3に設けられ、該冷却装置33からの冷気を筐体1内に導入するように構成される。これにより筐体1内の食品は冷気によって冷却され、当該食品を冷蔵保管できる。その際、筐体1外部の熱が複層透明部材であるガラス7や扉11を通して侵入しようとするが、側面ガラス9及び扉11内に設けられた真空断熱材26により熱の移動が遮られるため、効率のよい冷却を行なえ、省エネ効果が得られる。また、この場合の真空断熱材26は、例えばアルミニウムなどの金属箔を断熱材で囲み、真空状態を保持したものなどが好適である。   In the first and second embodiments described above, the showcase as a steamer has been described. However, the present invention can be similarly applied to a showcase as a cold insulator. In other words, the cooling apparatus in this case is configured such that a cooling device 33 (see FIG. 1) is provided in the base 3 in place of the steam generating device 2, and the cool air from the cooling device 33 is introduced into the housing 1. Is done. Thereby, the food in the housing 1 is cooled by cold air, and the food can be stored in a refrigerator. At that time, the heat outside the housing 1 tries to enter through the glass 7 and the door 11 which are multi-layer transparent members, but the heat transfer is blocked by the side wall glass 9 and the vacuum heat insulating material 26 provided in the door 11. Therefore, efficient cooling can be performed and an energy saving effect can be obtained. In addition, the vacuum heat insulating material 26 in this case is preferably, for example, a metal foil such as aluminum surrounded by a heat insulating material and kept in a vacuum state.

このように、筺体1内を冷却する冷却装置33を備えることによって、筺体1内にある被展示物を冷却保管することができるが、こうした保冷機能を備えたいわゆる保冷装置に対しても、筐体1の外部から内部への熱の侵入を抑制し、効果的に省エネ効果を高めることができる。   Thus, by providing the cooling device 33 that cools the inside of the housing 1, the exhibits in the housing 1 can be stored in a cooled state. The invasion of heat from the outside to the inside of the body 1 can be suppressed, and the energy saving effect can be enhanced effectively.

また、ここでも透明部材であるガラス13を有する扉11を筐体1に設け、ガラス13を除く扉11の例えば枠材12に真空断熱材26を配置すれば、上述した展示に関するデメリットなく省エネを実現できるとともに、保冷装置として使用した場合に、ガラス7だけでなく扉11からの熱の侵入を防ぎ、さらに効率的な冷却を行なうことができる。   In this case, if the door 11 having the glass 13 which is a transparent member is provided in the housing 1 and the vacuum heat insulating material 26 is disposed on the frame member 12 of the door 11 excluding the glass 13, for example, the energy can be saved without the disadvantages related to the exhibition described above. In addition to this, when used as a cold insulation device, it is possible to prevent heat from entering not only from the glass 7 but also from the door 11, and to perform more efficient cooling.

次に本発明の第3実施例について図9を参照して説明する。同図において、34は本実施例に適用する湿度制御手段である。まず、湿度制御手段34の構成について説明する。35は、筐体内湿度を検出する湿度センサーである。36は、使用者が希望する目標湿度(例えば40%、50%、60%および連続運転など)を設定するための湿度設定手段で、この湿度設定手段はスイッチなどからなる。2は実施例1と同じ蒸気発生装置で、当該蒸気発生装置2は、加湿ヒーターの加熱による蒸発によって蒸気を発生させるものである。37は、庫内湿度の状態や設定湿度を表示する湿度表示器で、この湿度表示器37はLEDあるいはLCDなどからなる。38は、前記蒸気発生装置2により発生した蒸気を筐体1内へ送風する送風機としての送風ファンである。   Next, a third embodiment of the present invention will be described with reference to FIG. In the figure, reference numeral 34 denotes humidity control means applied to this embodiment. First, the configuration of the humidity control means 34 will be described. Reference numeral 35 denotes a humidity sensor that detects the humidity inside the housing. Reference numeral 36 denotes humidity setting means for setting a target humidity desired by the user (for example, 40%, 50%, 60%, continuous operation, etc.), and this humidity setting means includes a switch or the like. 2 is the same steam generator as in Example 1, and the steam generator 2 generates steam by evaporation by heating of a humidifying heater. Reference numeral 37 denotes a humidity indicator that displays the state of the internal humidity and the set humidity, and the humidity indicator 37 includes an LED or an LCD. Reference numeral 38 denotes a blower fan as a blower that blows the steam generated by the steam generator 2 into the housing 1.

40は、前記湿度センサー35から入力した信号(筐体内湿度の検出値)と湿度設定手段36により設定された設定湿度とを比較判定する比較判定手段である。41は、前記比較判定手段40による判定結果に基づいて前記蒸気発生装置2の運転状態を自動的に設定する加湿量制御手段である。すなわち、この加湿量制御手段41は、比較判定手段40による判定結果に基づいて加湿量を自動的に判定し、蒸気発生装置2の出力を制御して所定の加湿量が得られるように制御するものである。42は前記比較判定手段40による判定結果に基づいて前記送風ファン38の回転数、つまり送風量を自動的に設定する送風機制御手段としての送風ファン制御手段である。すなわち、この送風ファン制御手段42は、送風ファン38の回転数を加湿量に応じて自動的に制御するものである。前記比較判定手段40、加湿量制御手段41および送風ファン制御手段42は、マイクロコンピュータ39により構成されている。   Reference numeral 40 denotes a comparison / determination unit that compares and determines a signal (a detected value of humidity inside the housing) input from the humidity sensor 35 and the set humidity set by the humidity setting unit 36. 41 is a humidification amount control means for automatically setting the operation state of the steam generator 2 based on the determination result by the comparison determination means 40. That is, the humidification amount control means 41 automatically determines the humidification amount based on the determination result by the comparison determination means 40, and controls the output of the steam generator 2 to obtain a predetermined humidification amount. Is. Reference numeral 42 denotes a blower fan control means as a blower control means for automatically setting the rotational speed of the blower fan 38, that is, the blown air amount, based on the determination result by the comparison determination means 40. That is, the blower fan control means 42 automatically controls the rotational speed of the blower fan 38 according to the humidification amount. The comparison determination means 40, the humidification amount control means 41 and the blower fan control means 42 are constituted by a microcomputer 39.

次に、上記構成についてその動作手順を説明する。まず切(運転停止)の状態から、操作パネル16の操作ボタン(図示せず)を押して蒸し運転の開始を指示すると、加湿量制御手段41は蒸気発生装置2を通電して水を加熱蒸発すると共に、送風ファン制御手段42は送風ファン38を通電し蒸気発生装置2から筐体1へ蒸気を送り込み、筐体1内部を蒸し加熱する加湿制御を行なう。そして、筐体1内の湿度を湿度センサー35により検出し、この筐体1内の湿度と湿度設定手段36により設定された設定湿度とを比較判定手段40により比較して、筐体1内の設定湿度以上であれば加湿量制御手段41によって蒸気発生装置2への電力供給量を減らし加湿を制限し、送風ファン制御手段42によって送風ファンの回転数を下げ送風量を減らし安定制御を行なう。   Next, the operation procedure of the above configuration will be described. First, when the operation button (not shown) on the operation panel 16 is pressed to instruct the start of the steaming operation from the off (operation stop) state, the humidification amount control means 41 energizes the steam generator 2 to heat and evaporate the water. At the same time, the blower fan control means 42 conducts humidification control in which the blower fan 38 is energized, steam is sent from the steam generator 2 to the housing 1, and the inside of the housing 1 is steamed and heated. The humidity in the housing 1 is detected by the humidity sensor 35, and the humidity in the housing 1 is compared with the set humidity set by the humidity setting means 36 by the comparison / determination means 40. If it is equal to or higher than the set humidity, the humidification amount control means 41 reduces the amount of power supplied to the steam generator 2 to limit humidification, and the blower fan control means 42 lowers the rotational speed of the blower fan to reduce the blown air amount and performs stable control.

一方、高湿度で使用する場合や、安定制御中に筐体1内部の温度が例えば扉11を開けるなどして通常ではあり得ない所定湿度未満に低下した場合、加湿量制御手段41によって蒸気発生装置2へ供給する電力量を増やし加湿を行なうと共に、送風ファン制御手段42によって送風ファン38の回転数を下げ送風量を増加させ加湿制御を行なう。以上が、蒸し器の湿度制御に関する基本動作である。   On the other hand, when used at high humidity, or when the temperature inside the housing 1 is lowered below a predetermined humidity that is not normal, for example, by opening the door 11 during the stable control, the humidification amount control means 41 generates steam. The amount of power supplied to the apparatus 2 is increased to perform humidification, and the blower fan control means 42 lowers the rotational speed of the blower fan 38 to increase the amount of blown air to perform humidification control. The above is the basic operation regarding the humidity control of the steamer.

以上のように本実施例では、被展示物である商品を展示する筐体1に真空断熱材26を備えると共に、筺体1内を加湿する蒸気発生装置2と、筐体1内の湿度を制御する手段としての湿度制御手段34とを備えている。   As described above, in this embodiment, the casing 1 that displays the product to be exhibited is provided with the vacuum heat insulating material 26, the steam generator 2 that humidifies the inside of the housing 1, and the humidity in the casing 1 is controlled. And a humidity control means 34 as a means to do this.

こうすると、筐体1内部の熱が側面ガラス9を通過しようとする際に、真空断熱材26により遮断されるため、側面ガラス9の表面からの熱の逃げを防いで、省エネ効果を高めることができる。さらに、筐体1内を所定の湿度に保つことができので、蒸し器として中華まんなどを展示販売する高湿度保温の用途だけでなく、加温器としてフランクフルトやコロッケなどを販売する低湿度保温の用途にも使用でき、共通の展示保管機で多用途に対応することが可能となる。したがって、用途に応じて複数のショーケースを用意する必要がなく、設備投資を低減できる。   In this way, the heat inside the housing 1 is blocked by the vacuum heat insulating material 26 when trying to pass through the side glass 9, thereby preventing the escape of heat from the surface of the side glass 9 and enhancing the energy saving effect. Can do. Furthermore, since the inside of the housing 1 can be kept at a predetermined humidity, it is not only used for high-humidity heat insulation for displaying and selling Chinese buns as steamers, but also for low-humidity heat retention for selling Frankfurt and croquettes as warmers. It can be used for various purposes with a common exhibition storage machine. Therefore, it is not necessary to prepare a plurality of showcases according to the use, and the capital investment can be reduced.

また、本実施例では湿度表示器37を備えているので、設定湿度や現在の筐体1内の湿度を適宜知ることが可能となる。   In addition, since the humidity indicator 37 is provided in the present embodiment, it is possible to appropriately know the set humidity and the current humidity in the housing 1.
