Moreover, the 1st cooler 22 and the 2nd cooler 31 are each connected to the cooling device 14 via the on-off valve etc. so that the cooling device 14 and a refrigerant | coolant may circulate.

  The reheating device 1 of the present embodiment heats or cools food for food stored in the cart by hot air or cold air supplied from a station. Even in the case where the heating time is insufficient, additional heating is possible. The operation of the reheating apparatus 1 will be described in detail with reference to the schematic process diagram of FIG. 8 and the flowchart of FIG.

  As shown in FIG. 8, the reheating device 1 has a reheating process K1 for reheating food once cooked, and an additional heating process K2 for performing additional heating after the reheating process K1. . Further, the reheating device 1 performs the exhaust heat insulation process K4 after the reheating process K1, and performs the exhaust heat insulation process K4 after performing the additional heating process K2. In the present embodiment, the reheating step K1 is also a heating / cooling step K3 including supply of hot air from the heating and cooling chamber 20 and supply of cold air from the cooling chamber 30. Hereinafter, a detailed description will be given with reference to the flowchart of FIG.

  The station 10 is turned on (step S1). Next, the cart 100 is connected to the station 10 (step S2). At this time, the food to be provided warmed is placed in the heating / cooling unit 124, and the food to be provided in the cold state is placed in the cooling unit 125 on the tray 127 and stored in the second cart 120, and the tray 127 is stored. The second cart 120 is stored in the first cart 110.

  And the operation start button in the operation part 16 is touched (step S3). The control unit 13 receives the operation start button touch signal, and the control unit 13 starts the cooling device 14 to start the cooling operation (step S4). In the heating / cooling chamber 20, the air sucked by the first suction unit 50 is cooled by the first cooler 22 in which the refrigerant circulates through the cooling device 14 and the opening / closing valve to cool the air and is stored in the heating / cooling unit 124 of the cart 100. Cool the food. Further, in the cooling chamber 30, the air sucked by the second suction unit 70 is cooled by the second cooler 31 in which the refrigerant circulates through the cooling device 14 and the opening / closing valve to cool the air and is stored in the cooling unit 125 of the cart 100. Cool the food.

  When the predetermined time has passed, the control unit 13 stops the circulation of the refrigerant to the first cooler 22 in the heating / cooling chamber 20, heats the heater 21, and the air supplied from the first air blowing unit 40 changes to hot air. The food stored in the heating / cooling unit 124 of the cart 100 is heated. On the other hand, for the purpose of preventing the movement of heat from the heating / cooling unit 124 to the cooling unit 125, the cooling chamber 30 always supplies cold air and constantly cools the food in the cooling unit 125. (Step S5).

  When the heating from the heating / cooling chamber 20 elapses for a predetermined time, the control unit 13 stops heating the heater 21, opens the opening / closing lid 26 of the exhaust duct 25, and removes hot air from the heating / cooling chamber 20 and the heating / cooling unit 124 to the exhaust duct 25. Exhaust heat insulation process K4 is discharged to the outside. In the exhaust heat insulation process K4, the exhaust duct 25 is opened for a predetermined time to discharge hot air from the heating and cooling chamber 20, and the temperature of the heating and cooling unit 124 is lowered to gradually cool the dishes and trays so that they can be served. And the opening and closing of the exhaust duct 25 and the heater 21 to maintain the heating and cooling unit 124 at a preset temperature, and the slow cooling operation is first started (slow cooling operation: step S6). .

  During reheating, the food is heated by hot air in a state where it is placed on the tableware 126. Therefore, the tableware 126 and the tray 127 themselves have heat during the heating process. It continues to be heated by the heat of the tableware 126 and the tray 127 itself. That is, even when the hot air heating in the reheating process K1 is completed, the food is continuously heated by the remaining heat of the tableware 126 and the tray 127.

  When the heating is completed and the slow cooling operation is started and the predetermined cooling time elapses, the slow cooling operation is completed. During this time, the heating by the residual heat to the food is settled, and the heating and cooling unit 124 is also lowered to the heat retention temperature (step S7). The operator can determine whether or not additional heating is necessary by notifying completion of the slow cooling operation (step S8). When it is determined that additional heating is not necessary, the cart 100 is disconnected from the station 10, the opening 113 is closed with the opening / closing door 113 a, and the food for meal placed on the tray 127 is served.

  By performing the exhaust heat insulation process K4, safety to the worker can be achieved. That is, immediately after the heating with hot air is completed, the tableware 126 and the tray 127 are hot and dangerous, and there is a danger that hot air blows out to an operator who opens the open / close door 114a of the cart 100 to measure the temperature of the food. By exhausting the hot air to the outside, the heating / cooling chamber 20 and the heating / cooling section 124 can be gradually cooled to open the door safely.

  In the exhaust heat retention step K4, the control unit 13 monitors the temperatures of the heating / cooling chamber 20 and the heating / cooling unit 124 by using the suction temperature sensor 54, and controls the heater 21 when the temperature is lower than the preset heat retention temperature to thereby achieve a predetermined heat retention. The temperature can be maintained, and when the temperature is too high, the opening / closing lid 26 of the exhaust duct 25 may be opened. As described above, the control unit 13 includes a heat retaining operation for controlling the output of the heater 21 in the heating / cooling chamber 20 and the opening / closing of the exhaust duct 25 to keep the heating / cooling unit 124 at the heat retaining temperature. It is possible to keep the temperature of the tray 127 constant.

  The exhaust heat retention step K4 is intended to gradually cool the heating / cooling unit 124, but after completion of the slow cooling operation, by keeping the temperature of the heating / cooling unit 124 constant, food and dishes are kept until the operation is stopped. Since the food can be stored at a temperature suitable for serving, the meal can be provided at a delicious temperature even if the timing of the serving is delayed.

  The start of the heating / cooling operation (S5) can be calculated based on the time required to heat the food (“heating by hot air” + “heating by residual heat of the food”), but may be set in advance. .

  If the operator opens the door 114a and measures the temperature of the food, and the food does not reach the predetermined temperature, or if there is insufficient heating due to an increase in the planned number of meals or menu changes, this embodiment The reheating apparatus 1 can perform the additional heating step K2.

  There are various methods for measuring the temperature of food, such as measuring by a temperature sensor by an operator or using a temperature sensor installed in the cart 100. However, the temperature reaches a temperature required for hygiene management (for example, 75 ° C.). If not, the additional heating step K2 is performed.

  The control unit 13 determines whether or not the additional heating button of the operation unit 16 is touched. When it determines with the additional heating button being touched (step S8 is Yes), the control part 13 starts an additional heating operation in order to perform the additional heating process K2 (step S10).

  The control part 13 is controlled so that the additional heating process K2 can be performed when discharge of hot air is started by the slow cooling operation of the exhaust heat retention process K4. Although it is control which lowers the temperature of the heating / cooling unit 124 to a safe state as much as possible, if the additional heating step K2 is performed before the completion of the slow cooling operation, the heating is applied before the temperature is lowered to the heat retention temperature. May overheat. Therefore, it is desirable that the additional heating step K2 be operable after the slow cooling operation, which not only ensures the safety of an operator who wants to measure the temperature of the food, but also heating by the residual heat of the tableware 126 and heating by the additional heating. And can be prevented from overheating.

  In order to control the control unit 13 so that the additional heating process K2 can be performed only after completion of the slow cooling operation in the exhaust heat retention process K4, for example, an “additional heating” button is displayed on the operation unit 16 after the completion of the slow cooling operation. By providing a protective function such that the arranged additional heating button is movable, additional heating can be performed after completion of the slow cooling operation without mistakes by the operator.

  The additional heating process K2 is automatically stopped after a predetermined time (for example, a maximum of 30 minutes) has elapsed in order to prevent the worker from arbitrarily stopping or heating for a long time due to the worker's forgetfulness. Further, in order to provide meals early, it is desirable to perform additional heating at a temperature equal to or higher than the set temperature of the reheating step K1. By setting at least a temperature equal to or higher than the heat retaining temperature, heating beyond the heat retaining temperature is additionally performed, and the meal can be heated and provided earlier than waiting at the heat retaining temperature.

  In addition heating process K2, control part 13 closes opening-and-closing lid 26 of exhaust duct 25, and switches the output of a heater to control of additional heating process K2. In the additional heating step K2, food can be efficiently heated by suppressing discharge of hot air from the exhaust duct 25.

  Further, it is desirable that the additional heating step K2 can be operated during the reserved operation. During the reserved operation, the heating temperature and the heating time are set in advance for each meal time by the number of meals and menu. If heating is insufficient, such as when the number of meals suddenly changes or the menu is changed, the setting of heating switches to the setting of the next meal once the operation is stopped to start the operation again. The same heating may not be possible. On the other hand, it is also possible to switch the operation mode to manual operation and perform additional heating, but if you forget to return from manual operation to reserved operation, it will be heated even when it is time to heat the next meal There is a risk that will not be done. Therefore, by enabling the additional heating step K2 in advance during the reserved operation, the additional heating can be easily performed under the same heating conditions as the immediately preceding heating without switching the heating setting.

  When the additional heating operation is completed after the elapse of a predetermined time, the exhaust heat retention step K4 is started as in step S6. First, the opening / closing lid 26 of the exhaust duct 25 is opened, hot air in the heating / cooling chamber 20 and the heating / cooling unit 124 is discharged, and a slow cooling operation is started (step S11). Therefore, since the inside of the heating / cooling chamber 20 and the heating / cooling unit 124 is gradually cooled even after the additional heating, the operator can open and close the open / close door 114a of the cart 100 in a safe state.

  When the slow cooling operation of the exhaust heat insulation process K4 is completed, the operator is notified that the slow cooling after the additional heating has been completed by flashing a button, sound, buzzer, or the like (step S12). Then, the temperature of the heating / cooling unit 124 is kept constant until the operation is stopped by the heat insulation operation to be operated next, and the tableware and the tray are stored at a temperature suitable for serving. The control unit 13 determines whether or not the operation stop button has been touched (step S13). When it is determined that the operation stop button has been touched (step S13 is Yes), the operation is ended (step S14).

  When the additional heating process K2 is not necessary, the additional heating button is not touched, so the control unit 13 determines that the additional heating button is not touched (No in step S8), and then the operation stop button is displayed. It is determined whether or not it is touched (step S9), and when it is determined that the operation stop button is touched (step S9 is Yes), the operation is terminated (step S14).

  In the reheating process K1 (heating / cooling process K3) and the additional heating process K2, the cooling chamber 30 is always driven and ends simultaneously with the end of the operation (step S14). That is, the control unit 13 controls the supply of the cold air from the cooling chamber 30 even after the heating / cooling step K3 is completed, and supplies the cold air from the cooling chamber 30 also in the additional heating step K2. Thereby, the inside of the cooling unit 125 of the cart 100 is always cooled, and the temperature rise due to the heat from the heating and cooling unit 124 can be prevented.

  When the operation is finished (step S14), the worker can detach the cart 100 from the station 10 (step S15) and perform the catering with the cart 100 while the second cart is stored.

  The operation end is not limited to the operation stop button, and may be automatically ended after a predetermined time has elapsed, and the additional heating can be performed even after the above-described additional heating step K2. Note that this additional heating is unscheduled and needs to be arranged as soon as possible.Therefore, when the additional heating operation is completed, the operator is notified with a buzzer or the like, and the operation is stopped without waiting for completion of the slow cooling operation. , And serving by the cart 100 may be prompted.

  10 to 12 are flowcharts showing an example of the operation of the operation unit 16. An example of the operation will be described with reference to FIGS.

  When the power of the station 10 is turned on (S 1), “standby” is displayed on the screen of the operation unit 16. In the present embodiment, the operation unit 16 is a touch panel type having a UI (user interface), and various displays and push buttons are arranged on the panel. The operation unit 16 is not limited to a touch panel type, and may be a hard button type, and is not particularly limited.

  Next, when the cart 100 is connected to the station 10 (S2), the “waiting for cart connection” display on the operation unit 16 is switched to the “cart connection release” display. At this time, the character color of the button may be reversed to emphasize that the function of the button has been changed.

  The operation start button on the operation unit 16 is touched (S3). For example, when the “operation start” display button of the operation unit 16 is pressed for a long time, the light turns blue and “operation stop” is displayed, and the cooling operation is started (S4). In addition, the “standby” display is switched to the “ALL cooling operation” display. Then, for example, about 20 minutes after the start of cooling, the inside of the cart 100 is kept in a chilled state.

  Then, for example, the control unit 13 prepares for switching the air in the heating / cooling chamber 20 from the cold air to the hot air from 5 minutes before the start of heating, so the display of “ALL cooling operation” is switched to the “heating preparation” display.

  When the heating / cooling operation is started (S5), the “heating preparation” display is switched to the “heating / cooling operation” display. The air in the heating / cooling chamber 20 is switched to hot air in accordance with the meal time, and the food in the heating / cooling unit 124 is started to be heated. For example, hot vegetables are kept hot and cold dishes are kept cold.

  When the slow cooling operation is started (S6), the “heating / cooling operation” display is switched to the “cooling down” display. In addition to the state where the heater 21 is stopped and only the fan 43 is operated, the open / close lid 26 of the exhaust duct 25 is opened, and hot air is discharged. As a result, wind at a lower temperature than that in the heating / cooling operation is supplied to the heating / cooling unit 124. Then, the temperature of the heating / cooling unit 124 gradually decreases, and is settled to a temperature at which the tableware 126 that has become hot with hot air can be touched.

  When the slow cooling operation of the exhaust heat insulation process K4 is completed (S7), the “Cooling down” display is changed to “Completed” display, and the heat insulation operation is started. Notification to the operator of completion is performed by a buzzer, sound, blinking of a display button, or the like. At the same time, an “additional heating” button indicating that the additional heating step K2 may be performed is displayed. When the additional heating process K2 is not required, the cart 100 is separated from the station 10 and is arranged. For example, the operation is stopped by touching the “stop operation” display button (step S14), and then the “cart connection release” display button is touched (step S15) to release the connection between the station 10 and the cart 100. Can do.

  The additional heating operation (S10) of the additional heating step K2 is started by touching the displayed “additional heating” button. During the additional heating, the “additional heating” button is reversed, and the “complete” display is switched to the “heating / cooling operation” display. When the additional heating is completed, the “heating / cooling operation” display is switched to “completed” display, and the display of the “additional heating” button is switched to “additionally heated” as in step S7. Notification to the worker of completion of heating is performed by a buzzer, sound, blinking of a display button, or the like.

  Although FIG. 10 to FIG. 12 show an example of the operation of the operation unit 16, the operation unit 16 may be a hard button type, a voice input type, or a communication type with a terminal, and is not limited to the above example.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimension, numerical value, form, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

  The reheating apparatus according to the present invention can be applied to a field where additional heating is required for foods and the like arranged vertically in a cart.
