Description

本発明は、病院や老人ホーム等において給食の保冷,加熱及び配膳を行うための配膳カートのように、冷却された状態でトレーに載せられた料理を一時冷蔵保管し、所定の時刻になったらそれらを加熱して配膳可能な状態にする配膳装置に関するものである。   The present invention temporarily stores refrigerated dishes placed on a tray in a chilled state, such as a food cart for cold storage, heating, and serving at a hospital or a nursing home, and when a predetermined time comes. The present invention relates to a laying apparatus that heats them so that they can be laid out.

病院の入院患者用食事は、それぞれの患者の病状に合わせて多彩なメニューを用意する必要があるが、従来は、それぞれの病院内に厨房を設け、そこで病院自らが調理して提供するか、あるいは、調理を外部の調理会社に依頼して提供するようにしていた。   For hospital inpatient meals, it is necessary to prepare various menus according to the medical condition of each patient, but in the past, a kitchen was set up in each hospital, and the hospital itself cooked or provided it, Alternatively, cooking was requested from an external cooking company.

しかし、そのように、それぞれの病院毎に調理を行うには、設備的及び人的に無駄が大きく非効率的である。そこで、それを解決するため、特許文献1に示されるような給食システムが開発されている。   However, as such, in order to cook for each hospital, it is wasteful and inefficient in terms of equipment and human resources. Then, in order to solve it, the lunch system as shown by patent document 1 is developed.

すなわち、複数の病院からの注文に応じて種々の料理が調理センターで調理され、クックチル処理、あるいは冷凍処理が施された後、浜底面に銀ペーストよりなる導電層が設けられた食器に入れられてトレー上に配置される。それらトレーに載せられた料理は、多数の区画室と冷却ユニットとを具えた配膳カートに収納された状態で、それぞれの病院に配送される。   That is, various dishes are cooked at a cooking center according to orders from a plurality of hospitals, cook chilled or frozen, and then placed in a tableware provided with a conductive layer made of silver paste on the bottom of the beach. Placed on the tray. The dishes placed on these trays are delivered to each hospital in a state of being stored in a serving cart having a number of compartments and cooling units.

配膳カートの各区画室の底部は、内部所定位置に複数の誘導加熱コイルが埋め込まれた加熱プレートで構成されており、各区画室に収納されるトレーは、加熱プレートの誘導加熱コイルに対して常に一定の位置に載置される。また、トレー上の各加熱用食器は、位置決め手段により常に所定の位置になるように載せられており、結局、それぞれの加熱用食器は、常に、各誘導加熱コイルに対応した位置に配置され、誘導加熱コイルに高周波電流が流されると導電層に渦電流が流れて熱が発生し、食器が加熱され、その中の食材が加熱されるようになっている。   The bottom of each compartment of the layout cart is composed of a heating plate in which a plurality of induction heating coils are embedded in a predetermined position inside, and the tray stored in each compartment is always constant with respect to the induction heating coil of the heating plate. It is placed at the position. In addition, each heating tableware on the tray is placed so as to be always in a predetermined position by the positioning means, and eventually each heating tableware is always arranged at a position corresponding to each induction heating coil, When a high frequency current is passed through the induction heating coil, an eddy current flows through the conductive layer to generate heat, the tableware is heated, and the foodstuffs therein are heated.

そして、配送中及び病院での待機中は、上記冷却ユニットから冷気供給ダクトを介して上下方向に多段に配列された各区画室内に冷気を供給して冷蔵状態を保ち、所定の時間になったら前記各誘導加熱コイルに高周波電流を流して加熱調理を行った後、配膳カートからトレーを取り出して配膳を行う。   Then, during delivery and waiting in the hospital, cold air is supplied from the cooling unit to the compartments arranged in multiple stages in the vertical direction through the cold air supply duct to maintain the refrigerated state, and when a predetermined time is reached After the high frequency current is applied to each induction heating coil to perform cooking, the tray is taken out from the serving cart and served.

このようにすれば、それぞれの患者に合った料理を、設備的及び人的な無駄を削減しながら効率的に提供できる。
特開2003-219918号公報(A47B 31/02)
In this way, food suitable for each patient can be efficiently provided while reducing facility and human waste.
JP2003-219918A (A47B 31/02)

ところで、このような配膳カートでは、冷凍食材を使った場合は、配膳前に、冷凍された食材をまず解凍してから加熱を行うことになる。その際、従来の配膳カートでは、解凍にかかる時間だけ、通常の場合より時期を早めて加熱を開始することになる。そして、解凍時間をできるだけ短くするため、解凍中は、誘導加熱コイルを大出力で運転することになる。   By the way, in such a distribution cart, when frozen foods are used, the frozen foods are first thawed before heating. At that time, in the conventional trolley cart, heating is started earlier than usual in the time required for thawing. And, in order to shorten the thawing time as much as possible, the induction heating coil is operated at a high output during thawing.

冷凍食材を加熱する場合の従来の配膳カートの庫内及び食材の温度変化を図5に示す。図5において、曲線Aは、食材の下端部、すなわち、食器底面に接触している部分の温度変化を示し、曲線Bは、食材中心部の温度変化を示し、曲線Cは、食材表面の温度変化を示し、曲線Dは、庫内温度の変化を示している。   FIG. 5 shows changes in the temperature of the conventional food cart and the food when the frozen food is heated. In FIG. 5, curve A shows the temperature change of the lower end portion of the food, that is, the portion in contact with the bottom of the tableware, curve B shows the temperature change of the food center, and curve C shows the temperature of the food surface. The curve D shows the change of the internal temperature.

時刻Tに、庫内への冷気の供給を止め、加熱を開始すると、食材の下端部は、誘導加熱コイルで加熱される食器に直に接しているため、温度が急激に上昇するが、食材中心部及び表面部の温度は、時刻T1に解凍が完了するまでは、あまり温度上昇しない。そして、解凍が完了した後は、食材の下端部,中心部及び表面部の温度は、それぞれ上昇して加熱が進み、時刻T2で加熱が完了する。 At time T 0 , when the supply of cold air to the cabinet is stopped and heating is started, the lower end of the food is in direct contact with the tableware heated by the induction heating coil, so the temperature rises rapidly. temperature of foodstuffs center and surface portions until thawed time T 1 is completed, not so much temperature rise. Then, after thawing is complete, the lower end portion of the foodstuff, the temperature of the central portion and the surface portion proceeds rise to heating each heating at time T 2, is completed.

図5から明らかなように、従来の配膳カートでは、解凍時から加熱完了までの間、食材の下端部,中心部及び表面部で大きな温度差が生じてしまい、料理の出来上がりが不良になるという問題点があった。また、解凍時には誘導加熱コイルを大出力で運転する必要があり、それをカートの全区画室で同時に行うことになるため、容量の大きな電源が必要になるという問題点もあった。   As is apparent from FIG. 5, in the conventional cart, from the time of thawing to the completion of heating, a large temperature difference occurs at the lower end portion, the central portion and the surface portion of the food, resulting in poor cooking. There was a problem. In addition, it is necessary to operate the induction heating coil with a large output at the time of thawing, and this is performed at the same time in all compartments of the cart.

本発明は、そのような問題点に鑑み、解凍時から加熱完了までの間、食材の下端部,中心部及び表面部で大きな温度差が生じないようにし、かつ、電源の容量を低くできるようにすることを目的とするものである。   In view of such a problem, the present invention prevents a large temperature difference from occurring at the lower end portion, the central portion, and the surface portion of the food from the time of thawing to the completion of heating, and can reduce the capacity of the power source. The purpose is to make it.

前記課題を解決するため、請求項1に記載の配膳装置は、食材を盛り付けた複数の食器を載置したトレーを収納する複数の区画室と、該区画室内に収納された前記食材を加熱するための加熱装置と、前記区画室内に冷気を送り込む冷却装置とを具えた配膳装置であって、前記冷却装置を運転して前記区画室内を冷蔵温度に保つ保冷モードと、前記加熱装置を高出力で動作させて前記食材を加熱する加熱モードと、前記冷却装置を運転するとともに、前記加熱装置を加熱モードの出力より低い出力で動作させて解凍を行う解凍モードとを具え、冷凍食材を加熱する際には、前記加熱モードを実行する前に、保冷のため運転していた前記冷却装置をそのまま運転させて、区画室内に冷気を供給しながら前記解凍モードを実行することを特徴とする。 In order to solve the above-mentioned problem, the laying apparatus according to claim 1 heats the food stored in the plurality of compartments storing a tray on which a plurality of dishes on which the food is arranged are placed, and the food stored in the compartments. And a cooling device that feeds cold air into the compartment, wherein the cooling device is operated to keep the compartment at a refrigeration temperature, and the heating device has a high output. The frozen food is heated by operating in the heating mode for heating the food and operating the cooling device and the thawing mode for operating the heating device at an output lower than the output of the heating mode to perform thawing. the time before running the heating mode, the cooling device was driving for cold as it is operated, and executes the decompression mode while supplying cooling air to the compartment

本発明の配膳装置は、次のような効果を奏する。   The laying apparatus of the present invention has the following effects.

本発明の配膳装置は、次のような効果を奏する。
すなわち、請求項1に記載の配膳装置は、保冷モードと、加熱モードとに加えて、冷却装置を運転するとともに、加熱装置を加熱モードの出力より低い出力で動作させて解凍を行う解凍モードとを持たせ、冷凍食材を加熱する際には、前記加熱モードを実行する前に、保冷のため運転していた前記冷却装置をそのまま運転させて、区画室内に冷気を供給しながら前記解凍モードを実行するようにしたので、食材の各部で大きな温度差が生じず、かつ、電源の容量を低く抑えながら冷凍食材の解凍が可能になる。また、解凍中、冷気により食材の衛生状態は保たれるため、解凍をじっくり時間をかけて行うことができ、さらに、加熱モードにおける加熱は、食材が解凍されて、熱伝導が良くなった状態で行われるため、食材の各部で大きな温度差が生じることなく加熱ができる。
The laying apparatus of the present invention has the following effects.
In other words, in addition to the cold insulation mode and the heating mode, the catering apparatus according to claim 1 operates the cooling device and operates the heating device at an output lower than the output of the heating mode to perform thawing. When the frozen food is heated, before the heating mode is performed, the cooling device that has been operated for cold storage is operated as it is, and the thawing mode is set while supplying cold air to the compartment. Since it was made to perform, a big temperature difference does not arise in each part of a foodstuff, and it becomes possible to thaw | freeze a frozen foodstuff, suppressing the capacity | capacitance of a power supply low. In addition, during the thawing, the sanitary state of the food is maintained by cold air, so the thawing can be performed over time, and the heating in the heating mode is a state where the food is thawed and the heat conduction is improved Therefore, heating can be performed without causing a large temperature difference in each part of the food material.

以下、本発明の実施例を図面に基づいて詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

図1は、本発明を適用する配膳カートの一例を示す図であり、図2は、その水平断面図である。図1,図2において、1はコントロールユニット収納部、2はコントロールパネル、3,4は扉、5は加熱プレート、6は区画室、7は仕切板、8は冷却ユニット、9は蒸発器、10は冷却ファン、11は冷気供給ダクト、12は加熱空間送風ファン、13は吸気ダクト、14はパワーアシスト車輪、15はキャスター、16はハンドル、17はトレー、18は加熱用食器、19は非加熱用食器、20は冷気回収ダクトである。   FIG. 1 is a view showing an example of a layout cart to which the present invention is applied, and FIG. 2 is a horizontal sectional view thereof. 1 and 2, 1 is a control unit storage section, 2 is a control panel, 3 and 4 are doors, 5 is a heating plate, 6 is a compartment, 7 is a partition plate, 8 is a cooling unit, 9 is an evaporator, 10 is a cooling fan, 11 is a cool air supply duct, 12 is a heating space blower fan, 13 is an intake duct, 14 is a power assist wheel, 15 is a caster, 16 is a handle, 17 is a tray, 18 is a tableware for heating, and 19 is non A tableware for heating 20 is a cold air collecting duct.

配膳カートの庫室は、前後左右にそれぞれ二分されており、また、上下方向は加熱プレート5により区切られていて、多数の区画室6が多段に形成されている。各区画室6には、それぞれに食材を盛り付けた食器を載せたトレー17が収納されるようにしている。トレー17上の食器は、浜底面に銀ペーストよりなる導電層が設けられた加熱用食器18とそのような導電層のない非加熱用食器19とが左右に分けられており、非加熱用食器19が内側になるようにしている。観音開きの扉3,4は、カートの前面と後面に設けられていて、前後からトレー17を出し入れできるようにしている。   The storage room of the layout cart is divided into front, rear, left and right, respectively, and the vertical direction is divided by the heating plate 5 so that a number of compartments 6 are formed in multiple stages. Each compartment 6 accommodates a tray 17 on which tableware with ingredients is placed. The tableware on the tray 17 is divided into a tableware for heating 18 having a conductive layer made of silver paste on the bottom of the beach and a tableware 19 for non-heating without such a conductive layer. 19 is on the inside. The double doors 3 and 4 are provided on the front and rear surfaces of the cart so that the tray 17 can be inserted and removed from the front and rear.

各区画室6の底面を構成する加熱プレート5は、内部所定位置に複数の誘導加熱コイル(図示せず)が埋め込まれている。そして、各区画室6に収納されるトレー17は、加熱プレート5の後端縁の周壁と扉3,4により前後方向の位置が決められ、加熱プレート5の左右両側縁の周壁により左右方向の位置が決められて、加熱プレート5の誘導加熱コイルに対して常に一定の位置に載置される。また、トレー17の上の各加熱用食器18は、位置決め手段により常に所定の位置になるように載せられており、結局、それぞれの加熱用食器18は、常に、各誘導加熱コイルに対応した位置に配置され、誘導加熱コイルに高周波電流が流されると導電層に渦電流が流れて熱が発生し、食器が加熱される。   A plurality of induction heating coils (not shown) are embedded in predetermined positions inside the heating plate 5 constituting the bottom surface of each compartment 6. The tray 17 accommodated in each compartment 6 is positioned in the front-rear direction by the peripheral wall of the rear end edge of the heating plate 5 and the doors 3, 4, and is positioned in the left-right direction by the peripheral walls of the left and right side edges of the heating plate 5. And is always placed at a fixed position with respect to the induction heating coil of the heating plate 5. In addition, each heating tableware 18 on the tray 17 is always placed at a predetermined position by the positioning means. After all, each heating tableware 18 is always in a position corresponding to each induction heating coil. When a high frequency current is passed through the induction heating coil, an eddy current flows through the conductive layer to generate heat, and the tableware is heated.

さらに、各区画室6内には、区画室6を左右に二分して外側部分の加熱空間6aと内側部分の冷蔵保持空間6bに分けられるように仕切板7が設けられており、その加熱空間6aに加熱用食器18が置かれ、冷蔵保持空間6bに非加熱用食器19が置かれるようにしている。そして、加熱空間6a内で各誘導加熱コイルにより加熱用食器18が加熱される間、冷蔵保持空間6bには、配膳カートの底部に設けられた冷却ユニット8の蒸発器9で冷却された冷気が、冷却ファン10により冷気供給ダクト11を介して供給される。冷気供給ダクト11から冷蔵保持空間6bに供給された冷気は、冷気回収ダクト20を介して吸気ダクト13に戻り、再び蒸発器9により冷却されて冷気供給ダクト11に送られる。そのように冷気が循環して非加熱用食器19が冷却される。その結果、区画室6の中では、非加熱用食器19の食材を冷蔵しながら、加熱用食器18の食材の加熱が可能になる。   Further, in each compartment 6, a partition plate 7 is provided so that the compartment 6 is divided into right and left and divided into an outer portion heating space 6a and an inner portion refrigeration holding space 6b, and the heating space 6a. The heating tableware 18 is placed on the refrigerated holding space 6b, and the non-heating tableware 19 is placed on the refrigerated holding space 6b. And while the tableware 18 for a heating is heated by each induction heating coil within the heating space 6a, the cold air cooled with the evaporator 9 of the cooling unit 8 provided in the bottom part of the distribution cart is received in the refrigeration holding space 6b. The cooling fan 10 supplies the air through a cold air supply duct 11. The cold air supplied from the cold air supply duct 11 to the refrigerated holding space 6 b returns to the intake duct 13 through the cold air recovery duct 20, is cooled again by the evaporator 9, and is sent to the cold air supply duct 11. In this way, the cool air circulates and the non-heating tableware 19 is cooled. As a result, in the compartment 6, it is possible to heat the ingredients of the heating tableware 18 while refrigeration of the ingredients of the non-heating tableware 19.

そして、配送中や待機中も、蒸発器9で冷却された冷気が、冷却ファン10により冷気供給ダクト11を介して冷蔵保持空間6bに供給される。また、加熱空間6aは、最上部の区画室天井の上に断熱隔壁で冷気回収ダクト20と連通させる形で囲って形成したダクトから、加熱空間送風ファン12により冷気を供給して内部を保冷できるようにしている。   The cool air cooled by the evaporator 9 is supplied to the refrigerated holding space 6b through the cool air supply duct 11 by the cooling fan 10 during delivery and standby. Further, the heating space 6a can be kept cool by supplying cold air from the duct formed by surrounding the ceiling of the uppermost compartment with a heat insulating partition wall so as to communicate with the cold air recovery duct 20 by the heating space blower fan 12. I am doing so.

図3は、配膳装置の制御ブロック図である。コントロールパネル2は、各種表示ランプ加熱時間を設定するための入力装置、設定時間を表示する表示器、及び、各種表示ランプ等を具えている。コントロールユニット21は、タイマを内蔵しており、所定の時刻になったらドライブ回路22〜25を制御して、前記誘導加熱コイルによる加熱を開始させる。また、冷却ユニット制御回路26やファン制御回路27を介して、冷却ユニット8,冷却ファン10,加熱空間送風ファン12のオンオフ制御を行う。   FIG. 3 is a control block diagram of the layout apparatus. The control panel 2 includes an input device for setting various display lamp heating times, a display for displaying the set time, and various display lamps. The control unit 21 has a built-in timer, and controls the drive circuits 22 to 25 to start heating by the induction heating coil when a predetermined time comes. Further, on / off control of the cooling unit 8, the cooling fan 10, and the heating space blower fan 12 is performed via the cooling unit control circuit 26 and the fan control circuit 27.

ドライブ回路22〜25は、それぞれ、各区画室内の誘導加熱コイルを位置別に分担する。例えば、ドライブ回路22は、主菜用の誘導加熱コイルを分担し、ドライブ回路23は、副菜用の誘導加熱コイルを分担し、ドライブ回路24は、御飯用の誘導加熱コイルを分担し、ドライブ回路25は、汁物用の誘導加熱コイルを分担する。   The drive circuits 22 to 25 share the induction heating coil in each compartment by position. For example, the drive circuit 22 shares an induction heating coil for main dishes, the drive circuit 23 shares an induction heating coil for side dishes, and the drive circuit 24 shares an induction heating coil for rice. The circuit 25 shares the induction heating coil for the soup.

そして、それぞれのドライブ回路22〜25は、コントロールユニット21により制御され、その時々のメニュー,量、及び、加熱,保温,非加熱等の運転モードに応じて最適な加熱が行えるように、各区画室の誘導加熱コイルを作動させる。   Each of the drive circuits 22 to 25 is controlled by the control unit 21 so that each compartment can be optimally heated according to the menu, amount, and operation mode such as heating, heat retention, and non-heating. Actuate induction heating coil.

各誘導加熱コイルの加熱の強さは、それぞれの誘導加熱コイルを繰り返しオンオフさせ、その内のオフ期間の長さを変化させることにより調整することができる。そのように、誘導加熱コイルを繰り返しオンオフさせても、加熱に用いる食器は磁器製であるため熱容量が大きく、オン期間に蓄積した熱によりオフ期間にも温度を維持することができる。むしろ、温度の急激な上昇を防止して料理の焦げ付きを防止できる。   The intensity of heating of each induction heating coil can be adjusted by repeatedly turning on and off each induction heating coil and changing the length of the off period. As described above, even if the induction heating coil is repeatedly turned on and off, the tableware used for heating is made of porcelain, so that the heat capacity is large, and the temperature can be maintained during the off period by the heat accumulated during the on period. Rather, the temperature can be prevented from rising sharply and cooking can be prevented from being burnt.

このような配膳カートで、冷凍された食材を加熱して温かい料理を提供する場合、従来は、解凍にかかる時間だけ、通常の場合より時期を早めてフル出力で加熱を開始し、解凍が完了した後は、加熱出力を所定のプログラムに従って調整しながら加熱を継続し、加熱を完了させるようにしていた。しかし、本発明では、加熱モードのほかに解凍モードを設け、解凍と加熱調理とを分けて行うようにした。   In such a food cart, when heating frozen foods to provide warm dishes, heating is started at full output earlier than usual in the conventional way, and thawing is completed. After that, heating was continued while adjusting the heating output according to a predetermined program to complete the heating. However, in the present invention, in addition to the heating mode, a thawing mode is provided so that thawing and cooking are performed separately.

その解凍モードでは、保冷のため運転していた冷却ユニット8と冷却ファン10,加熱空間送風ファン12をそのまま運転させて、冷気供給ダクト11,冷気回収ダクト20を介して加熱空間6aに冷気を供給しながら、誘導加熱コイルに高周波電流を流して食器底面の導電層を介して冷凍食材を加熱して解凍を進める。その際、冷気により食材の衛生状態は保たれるため、解凍をじっくり時間をかけて行うことができ、誘導加熱コイルは、上記従来の方法で解凍を行う場合に比べて、10%程度の出力で運転することができる。   In the thawing mode, the cooling unit 8, the cooling fan 10, and the heating space blower fan 12 that have been operated for cold storage are operated as they are, and the cooling air is supplied to the heating space 6 a through the cold air supply duct 11 and the cold air recovery duct 20. Meanwhile, a high-frequency current is passed through the induction heating coil to heat the frozen food material through the conductive layer on the bottom of the tableware and to proceed with thawing. At that time, since the sanitary condition of the food is maintained by the cold air, the thawing can be performed over time, and the induction heating coil has an output of about 10% as compared with the case where the thawing is performed by the conventional method. You can drive at.

加熱空間6a内及び食材の温度変化を図4に示す。図5と同様に、曲線Aは、食材の食器底面に接触している部分の温度変化を示し、曲線Bは、食材中心部の温度変化を示し、曲線Cは、食材表面の温度変化を示し、曲線Dは、庫内温度の変化を示している。   FIG. 4 shows changes in the temperature of the heating space 6a and the ingredients. Similarly to FIG. 5, the curve A shows the temperature change of the portion of the food that is in contact with the bottom of the tableware, the curve B shows the temperature change of the center of the food, and the curve C shows the temperature change of the food surface. Curve D shows the change in the internal temperature.

解凍の開始時刻Tは、料理提供予定時刻と、解凍に必要な時間と加熱に必要な時間を考慮して決められる。そして、解凍の開始時刻Tになったら、冷却ユニット8と冷却ファン10,加熱空間送風ファン12をそのまま運転させて、冷気供給ダクト11を介して加熱空間6aに冷気を供給しながら、誘導加熱コイルを解凍モードの低出力で運転開始させる。その結果、庫内温度Dが10℃以下の保冷状態に維持されながら、食材の各部の温度A,B,Cが徐々に上昇し、解凍が進んでいく。その際、誘導加熱コイルを低出力で運転して、比較的長時間(30〜60分程度)をかけて解凍するので、食材の各部の温度A,B,Cには、あまり差ができない。そして、時刻T1に解凍が完了する。 The thawing start time T 0 is determined in consideration of the scheduled food provision time, the time required for thawing and the time required for heating. When the thawing start time T 0 is reached, the cooling unit 8, the cooling fan 10, and the heating space blower fan 12 are operated as they are, and the cooling air is supplied to the heating space 6 a through the cold air supply duct 11 while induction heating is performed. Start the coil at low power in thawing mode. As a result, the temperature A, B, C of each part of the food is gradually increased and thawing proceeds while the internal temperature D is maintained in a cold state of 10 ° C. or less. At that time, since the induction heating coil is operated at a low output and defrosted over a relatively long time (about 30 to 60 minutes), there is not much difference in the temperatures A, B and C of each part of the food. Then, the decompression is completed at time T 1 .

解凍が完了したら、誘導加熱コイルの運転を停止させ、その後は、加熱空間6aに冷気を供給し続けて、解凍された食材を保冷しておく。そして、所定の時刻T2になったら、加熱空間6aへの冷気の供給を止めて、誘導加熱コイルを加熱モードの高出力で運転を開始する。その結果、食材の各部の温度A,B,Cが上昇していくとともに、庫内温度Dも上昇していく。 When the thawing is completed, the operation of the induction heating coil is stopped, and thereafter, the cold air is continuously supplied to the heating space 6a to keep the thawed food material cold. Then, when it reaches a predetermined time T 2, by stopping the supply of cold air to the heated space 6a, starts operation of the induction heating coil with a high output of the heating mode. As a result, the temperature A, B, C of each part of the food material increases, and the internal temperature D also increases.

その際、食材は、冷蔵状態の温度から加熱するだけなので、誘導加熱コイルの出力を、従来の配膳カートの解凍時ほどには大きくする必要はなく、また、食材は、解凍されると熱伝導が良くなるため、食材各部の温度A,B,Cには、あまり大きな差はできない。   At that time, since the food is only heated from the temperature of the refrigerated state, it is not necessary to increase the output of the induction heating coil as much as when thawing the conventional food cart. Therefore, the temperature A, B, C of each part of the food cannot be greatly different.

このように、本発明によれば、解凍中及び加熱中に食材各部の温度に大きな差は生じず、料理の出来上がりが良くなる。また、解凍を、従来の方法で行う場合に比べて10%程度の出力で行うことができ、また、加熱は、従来でも、従来方法による解凍時の出力の数分の1程度で可能なので、電源の容量を従来のものの数分の1程度に抑えることができる。   As described above, according to the present invention, there is no great difference in the temperature of each part of the food during thawing and heating, and the finished dish is improved. In addition, thawing can be performed at an output of about 10% compared to the case where the conventional method is performed, and heating can be performed at a fraction of the output at the time of thawing by the conventional method. The capacity of the power supply can be suppressed to about a fraction of that of the conventional one.

なお、上記実施例では、配膳カートの場合で説明したが、本発明は、上記配膳カートと同様に多数の区画室と冷却ユニットと加熱装置とを具えるが、車輪,キャスターは有しない固定式の配膳装置にも適用可能である。   In the above embodiment, the case has been described in the case of a layout cart.
