In addition, air circulation paths are respectively formed.

  Next, the electrical configuration of the refrigeration apparatus 10 will be described with reference to FIG. The refrigeration apparatus 10 includes a control circuit in which a plurality of electronic components are mounted on a circuit board, and the control circuit includes a control unit 50 as shown in FIG. The control unit 50 performs a chilled storage mode for performing a chilled storage operation in which both the refrigerator compartment 21 and the warm compartment 22 are kept cold, and a reheating operation for keeping the refrigerator compartment 21 and heating the refrigerator compartment 22. The reheating mode to be performed can be switched. The control unit 50 includes a CPU 51, a memory 52, and a timer 53. Among these, the memory 52 includes a ROM, a RAM, an NV (nonvolatile) RAM, and the like, and various kinds of programs executed by the CPU 51 and operation information related to the operation of the refrigeration apparatus 10 described below are stored in the ROM. In the RAM, data related to various processes is temporarily stored. The timer 53 is for measuring time.

  When in the chilled storage mode, the control unit 50 controls the cooling device 38 to perform a chilled storage operation in which the temperatures of both the refrigerator compartment 21 and the warm compartment 22 are maintained at a chilled temperature of 5 ° C. or less. As a result, as shown in FIG. 4, the refrigerator compartment 21 and the refrigerator compartment 22 are cooled with the set temperature (set chill temperature) TA as a target temperature. The control unit 50 switches the chilled storage operation to the reheating mode at the set time t1 (a predetermined time before the serving time when the serving time is set). When the control unit 50 is in the reheating mode, the cooling device 38 and the heating device 34 are configured to perform a reheating operation in which the refrigerating chamber 21 is cooled by the cooling device 38 and the warming chamber 22 is heated by the heating device 34. To control. As a result, the refrigerator compartment 21 is cooled (defrosted) using a set temperature (set refrigerator temperature) TB higher than the preset temperature TA in the chilled storage operation as a target temperature, and the refrigerator compartment 22 is heated using the preset temperature TC as a target temperature. Is done. Therefore, in the reheating operation, the temperature of the warming chamber 22 is maintained substantially constant in the vicinity of the set temperature TC after being rapidly raised toward the set temperature TC. The set temperature TB of the refrigerating chamber 21 is a refrigerating temperature higher than the chilled temperature, and is set from a range of 5 ° C. to 10 ° C., for example, so that the period during which the compressor is stopped becomes longer. Thus, the defrosting of the cooler can be performed efficiently, so that a sufficient cooling capacity can be provided. At the end of the reheating operation, at time t2 (predetermined time before time t3 when the reheating operation ends), cooling of the refrigerator compartment 21 by the cooling device 38 continues, and the refrigerator compartment 22 by the heating device 34 continues. The cooling device 38, the heating device 34, and the second circulation fan 37 are controlled so that the second circulation fan 37 is driven to steam the interior of the warm storage chamber 22. Therefore, it can be said that the final stage of the reheating operation is a “steaming operation”. Further, (t2-t1) is a heating time, and (t3-t2) is a steaming time. In addition, the temperature of the refrigerator compartment 21 and the refrigerator compartment 22 is set by the control part 50 so that it may be in the range of a predetermined temperature difference (differential) with respect to each set temperature TA-TC. Is controlled on and off.

  On the input side of the control unit 50, as shown in FIG. 3, an operation unit 32 operated by a user, and temperature sensors (temperature measuring means) for measuring the temperatures of the refrigerator compartment 21 and the refrigerator compartment 22. 41) is connected. The temperature sensor 41 is made of, for example, a thermistor, and is installed inside the refrigerator compartment 21 and the refrigerator compartment 22, respectively. The operation unit 32 uses the touch panel function of the display panel 31 described above, and allows the user to perform operations such as starting or stopping the chilled storage operation of the cooling device 38. An example of an image displayed on the display panel 31 which is the operation unit 32 includes a home screen shown in FIG. On the home screen, as shown in FIG. 5, a display relating to the touch panel function is arranged at the lower end of the figure, and other displays are arranged on the upper side of the figure. Specifically, an operation button 32a constituting the operation unit 32 that can be operated by the user by a touch panel function is displayed at the lower end portion shown in FIG. 5 on the home screen. On the upper side of the home screen shown in FIG. 5 with respect to the operation button 32a, the temperatures of the refrigerator compartment 21 and the refrigerator compartment 22 measured by the temperature sensor 41, the current time, and the cart state (the cart is contained). If the cart is locked, “lock” is displayed), and the operating states of the cooling device 38 and the heating device 34 are respectively displayed. In addition, as the display related to the operation state of the cooling device 38 and the heating device 34, the display related to the remaining time until the start of operation and the remaining time until the operation is completed below each temperature of the refrigerator compartment 21 and the warm storage chamber 22. However, at the upper right end of each temperature of the refrigerator compartment 21 and the refrigerator compartment 22, it is “standby” if it is not in operation, “cold” if it is in a chilled storage operation, and it is in reheating operation or steaming operation. If so, a display such as “heating” is made (see FIGS. 5 to 7).

  As shown in FIG. 5, the operation button 32a constituting the operation unit 32 includes a breakfast start button 32a1, a lunch start button 32a2, a dinner start button 32a3, a precooling start button 32a4, a heat retention start button 32a5, and a setting button 32a6. It is. The breakfast start button 32a1, the lunch start button 32a2, and the dinner start button 32a3 are arranged so that the cooling device 38 and the breakfast start button 32a3 and the dinner start button 32a3, respectively, reach the set serving times (breakfast start time, lunch start time, and dinner start time). This is for executing a program for completing a series of operations (chilled storage operation and reheating operation) related to the heating device 34. Accordingly, when any one of the breakfast start button 32a1, the lunch start button 32a2, and the dinner start button 32a3 is touch-operated by the user, for example, the chilled storage operation of the cooling device 38 is performed at a predetermined time obtained by calculating backward from the serving time. Is supposed to start. The pre-cooling start button 32a4 is for executing a program for controlling the operation of the cooling device 38 so as to pre-cool the inside of the refrigerator compartment 21 and the refrigerator compartment 22. The heat insulation start button 32a5 is for executing a program for controlling the operation of the heating device 34 to keep the inside of the warm room 22 warm. The setting button 32a6 is for shifting from the above-described home screen to a setting screen (not shown) for performing various settings. On this setting screen, an operation for stopping the chilled storage operation can be performed. Therefore, for example, when it is necessary to replace food (cold or hot food) on the tray 19 after the chilled storage operation is started, the user stops the chilled storage operation from the setting screen. It is possible to perform the operation.

  As shown in FIG. 3, the warning unit 33, the cooling device 38, the heating device 34, and the circulation fans 36 and 37 are connected to the output side of the control unit 50. Accordingly, the warning unit 33, the cooling device 38, the heating device 34, and the circulation fans 36 and 37 are operated in accordance with a control signal from the control unit 50. Of these, the warning unit 33 uses the image display function of the display panel 31 described above, and performs “operation monitoring” to warn the user to perform an operation of starting the chilled storage operation of the cooling device 38. It is possible. Specifically, when the user performs an operation to stop the chilled storage operation from the setting screen described above, the warning screen 33a shown in FIG. 9 is displayed on the display panel 31. By displaying such a warning screen 33a on the display panel 31, the user is prompted to perform an operation to restart the chilled storage operation. As a result, it is possible to prevent with high certainty the situation in which the resumption of the stopped chilled preservation operation remains forgotten, and thus the situation where food is corrupted without being preserved in the chilled state is prevented with high certainty. . The “meal zone buttons” shown in FIG. 9 are the breakfast start button 32 a 1, the lunch start button 32 a 2, and the dinner start button 32 a 3. The “lever” is raised when the tray 19 is put in and out. It is a mechanism component (not shown) that is required to be in a state and is required to be in a lowered state when performing a chilled storage operation or the like.

  Control of the refrigeration apparatus 10 will be described. First, cooked hot food and cold food are chilled and stored in a prefabricated refrigerator (not shown) separate from the cold storage apparatus 10. Next, hot and cold foods taken out of the prefabricated refrigerator or the like are placed on the tray 19, each tray 19 is stored in a plurality of stages across the warming room 22 and the refrigerating room 21 of the cart 11, and the cart 11 is stored in the station 30. Put in. When the user touches one of the breakfast start button 32a1, the lunch start button 32a2, and the dinner start button 32a3 among the operation buttons 32a on the home screen displayed on the display panel 31, the control unit 50 As shown in FIG. 10, the chilled storage mode is initially set, and the chilled storage operation of the cooling device 38 and the circulation fans 36 and 37 is started (step S10). In the chilled storage mode, the control unit 50 sets both the warm room 22 and the cold room 21 to the set temperature TA according to the temperature in the warm room 22 and the cold room 21 measured by the temperature sensor 41. Then, a chilled storage operation for operating the cooling device 38 and the circulation fans 36 and 37 is performed. Note that the screen shown in FIG. 6 is displayed on the display panel 31 as the chilled storage operation is started.

  When the chilled storage operation is started, the control unit 50 determines whether or not an operation for stopping the chilled storage operation has been performed by the user from the setting screen of the display panel 31 as illustrated in FIG. 10 (step S11). ). When it determines with "YES" by the control part 50 in step S11, the control part 50 stops the chilled preservation | save operation | movement of the cooling device 38 and each circulation fan 36 and 37 (step S12). Then, the control part 50 displays the warning image 33a shown in FIG. 9 on the display panel 31 (warning part 33) (step S13). With the display of the warning image 33a, the user is prompted to perform an operation to restart the chilled storage operation. Subsequently, the control unit 50 determines whether or not an operation for restarting the chilled storage operation has been performed (step S14). If “NO” is determined by the control unit 50 in step S14, the process returns to step S14 again, and the state where the warning image 33a is displayed on the display panel 31 is maintained. On the other hand, when it is determined as “YES” by the control unit 50 in step S14, the control unit 50 deletes the warning image 33a of the display panel 31 and chilles the cooling device 38 and the circulation fans 36 and 37. The storage operation is started (step S15). Subsequently, the control unit 50 determines whether or not the timer 53 has reached the reheating operation start time t1 (step S16). In addition, when it determines with "NO" by the control part 50 in above-mentioned step S11, it transfers to said step S16.

  If it is determined as “NO” by the control unit 50 in step S16, the control unit 50 returns to step S11 as shown in FIG. 10, and has the user performed an operation to stop the chilled storage operation again? It is determined whether or not. On the other hand, when it is determined as “YES” by the control unit 50 in step S16, the control unit 50 changes from the chilled storage mode to the reheating mode, and the heating device 34, the cooling device 38, and the circulation fans 36 and 37 are changed. A reheating operation is started (step S17). In this reheating mode, the control unit 50 sets the refrigerator compartment 21 to the set temperature TB and the refrigerator compartment 22 to the set temperature TC according to the temperatures in the refrigerator compartment 22 and the refrigerator compartment 21 measured by the temperature sensor 41. Then, a reheating operation is performed to operate the heating device 34, the cooling device 38, and the circulation fans 36 and 37 so as to be respectively. Note that the screen shown in FIG. 7 is displayed on the display panel 31 as the reheating operation is started. In this reheating operation, when a predetermined heating time (t2-t1) has elapsed, heating of the warming chamber 22 by the heating device 34 is stopped, and the second circulation fan 37 is driven to steam the warming chamber 22. Subsequently, the control unit 50 determines whether or not the reheating operation end time t3 has been reached (step S18). If “NO” is determined by the control unit 50 in step S18, the process returns to step S18 again and the reheating operation is continued. On the other hand, when it is determined as “YES” by the control unit 50 in step S18, the control unit 50 stops the reheating operation of the heating device 34, the cooling device 38, and the circulation fans 36 and 37 (step S19). ). Note that the screen shown in FIG. 8 is displayed on the display panel 31 as the reheating operation ends.

  As described above, the refrigeration apparatus (cooling storage) 10 according to this embodiment includes the refrigeration room 21 and the warming room 22 that are storage rooms, and the refrigeration operation that cools the refrigeration room 21 and the warming room 22 that are storage rooms. A cooling device (cooling unit) 38 that performs the operation, an operation unit 32 that can operate the start or stop of the refrigeration operation of the cooling device 38, a warning unit 33 that can issue a warning to start the refrigeration operation, A control unit 50 that controls the operation of the cooling device 38 based on the operation by the unit 32 and controls the warning unit 33 to issue a warning when the operation unit 32 is operated to stop the refrigeration operation. Prepare.

  In this manner, when an operation for starting the refrigeration operation is performed in the operation unit 32, the cooling unit 38 is controlled by the control unit 50, thereby cooling the inside of the refrigeration chamber 21 and the warming chamber 22 that are storage rooms. Refrigerated operation is performed. When an operation for stopping the refrigeration operation is performed in the operation unit 32 in a state where the refrigeration operation is performed, the refrigeration operation is stopped by the control unit 50 controlling the cooling device 38. Here, in the case where the reason for stopping the refrigeration operation is, for example, the replacement of stored items stored in the refrigeration chamber 21 and the warming chamber 22 which are storage rooms, the refrigeration operation is started again. However, if the user forgets the operation of re-starting the refrigeration operation, there is a possibility that the stored items may be deteriorated without cooling the inside of the refrigerated room 21 and the warmed room 22 as storage rooms. In this respect, the control unit 50 controls the warning unit 33 to issue a warning as the operation unit 32 performs an operation to stop the refrigeration operation. Prompted to do. As a result, it is possible to prevent with high certainty the situation in which the resumption of the stopped refrigeration operation remains forgotten.

  The warning unit 33 includes a display panel (display unit) 31 that can display at least a warning image 33a. In this way, the control unit 50 can visually prompt the user to perform an operation of resuming the refrigeration operation by displaying the warning image 33a on the display panel 31.

  Further, the display panel 31 has an input position detection function for detecting an input position by the user, and the operation unit 32 includes the display panel 31. In this way, the user can start or stop the refrigeration operation of the cooling device 38 by performing position input based on the image displayed on the display panel 31 having the input position detection function.
