After 3 hours have passed from the start of the freeze (freezing) process, the control device 50 executes the retard (refrigerating) process. In the retard (refrigerating) step, the control device 50 controls the operation of the cooling device 20 based on the detection temperature of the temperature sensor 18 to control the temperature inside the storage 12 so as to be 2 ° C.

When a lower set lower limit temperature is detected, the operation of the cooling device 20 is stopped. When the cooling device 20 is operating, the air sent from the inside of the storage 12 to the temperature control space 16c of the duct passage 16 by the circulation fan 17 is cooled by exchanging heat with the evaporator 25. As shown by the arrow of the two-dot chain line in FIG. 4, the cooled air is sent to the storage 12 again through the vertical duct passage 16a and the horizontal duct passage 16b, and the inside of the storage 12 is cooled by the cooled air. Will be done.

When a predetermined time has elapsed from the start of the retard (refrigerating) process, the control device 50 executes the preheating process. In the preheating step, the control device 50 controls the operation of the cooling device 20 or the heater 31 based on the detected temperature of the temperature sensor 18, so that the temperature inside the storage 12 is controlled to 18 ° C. and the humidity is controlled. By controlling the operation of the humidifier 40 based on the detected humidity of the sensor 19, the humidity inside the storage 12 is controlled to be 85%. In an environment where the room temperature is higher than the set temperature of 18 ° C, the cooling device 20 is operated when the detection temperature of the temperature sensor 18 detects a set upper limit temperature higher than the set temperature of the storage 12 of 18 ° C. It is controlled so that the operation of the cooling device 20 is stopped when the detection temperature of the temperature sensor 18 detects a set lower limit temperature lower than the set temperature of the storage 12 of 18 ° C. When the cooling device 20 is operating, the air sent from the inside of the storage 12 to the temperature control space 16c of the duct passage 16 by the circulation fan 17 is cooled by exchanging heat with the evaporator 25. As shown by the arrow of the two-dot chain line in FIG. 4, the cooled air is sent to the storage 12 again through the vertical duct passage 16a and the horizontal duct passage 16b, and the inside of the storage 12 is cooled by the cooled air. Will be done.

On the other hand, in an environment where the room temperature is lower than the set temperature of 18 ° C, the heater 31 is operated when the detection temperature of the temperature sensor 18 detects a set lower limit temperature lower than the set temperature of the storage 12 of 18 ° C. When the detection temperature of the temperature sensor 18 detects a set upper limit temperature higher than the set temperature of the storage 12 of 18 ° C., the operation of the heater 31 is controlled to be stopped. When the heater 31 is operated, the air sent from the inside of the storage 12 to the temperature control space 16c of the duct passage 16 by the circulation fan 17 is heated by the heater 31. As shown by the arrow of the two-dot chain line in FIG. 4, the heated air is sent to the storage 12 again through the vertical duct passage 16a and the horizontal duct passage 16b, and the inside of the storage 12 is warmed by the heated air.

When the control device 50 detects the lower limit set humidity whose detection humidity by the humidity sensor 19 is lower than 75%, the humidifier 40 controls to humidify the humidity, and when the control device 50 detects the upper limit set humidity whose detection humidity by the humidity sensor 19 is higher than 75%. It is controlled to stop the humidification by the humidifier 40. When the inside of the storage 12 is humidified by the humidifier 40, the humidity of the storage 12 is controlled so that water is intermittently sprayed from the spray nozzle 41 of the humidifier 40 by alternately repeating the spray time and the standby time. ing. By intermittently spraying water from the spray nozzle 41, the sprayed water can be vaporized in the standby time and sufficiently distributed in the storage 12. Further, in this embodiment, the spraying time from the spray nozzle 41 is set to 2 seconds, and the standby time of the spray nozzle 41 is defined by the temperature and humidity in the storage 12 as shown in FIG. There is. In addition, although the waiting time specified by some temperature and some humidity is shown in FIG. 7 and the waiting time specified by other temperature and humidity is omitted, the waiting time of temperature and humidity not shown is shown. It has a proportional relationship with the waiting time for each temperature and the waiting time for each humidity shown. P
When humidifying by the humidifier 40 based on the detected humidity of the humidity sensor 19 during the preheating step, the control device 50 has a standby time defined by the temperature and humidity in the storage 12 described above. The standby time is derived from the detected temperature of the temperature sensor 18 and the detected humidity of the humidity sensor 19. When the control device 50 detects the lower limit set humidity in which the humidity detected by the humidity sensor 19 is lower than 75%, the water supply valve 42b is opened for 2 seconds, which is the spray time, and water is atomized from the spray nozzle 41 for 2 seconds, which is the spray time. It is controlled to repeatedly execute spraying in a shape and closing the water supply valve 42b at the calculated standby time to wait for spraying water. When water is sprayed from the spray nozzle 41 in the form of a mist, the air sent from the storage 12 to the duct passage 16 by the circulation fan 17 is the water sprayed from the spray nozzle 41 in the vertical duct passage 16a. It is vaporized and humidified, and as shown by the arrow of the two-point chain line in FIG. 4, the humidified air is sent to the storage 12 again through the vertical duct passage 16a and the horizontal duct passage 16b, and the inside of the storage 12 is inside. It is humidified by the humidified air.

Two hours after the start of the preheating step, the control device 50 executes the fermentation (hoiro) step. In the proofing (fermentation) step, the control device 50 controls the operation of the heater 31 based on the detection temperature of the temperature sensor 18, so that the temperature inside the storage 12 is controlled to 35 ° C., and the humidity sensor By controlling the operation of the humidifier 40 based on the detected humidity of 19, the humidity inside the storage 12 is controlled to be 85%.

When the detection temperature of the temperature sensor 18 detects a set lower limit temperature lower than the set temperature of the storage 12 of 35 ° C, the heater 31 is controlled to operate, and the detection temperature of the temperature sensor 18 is the set temperature of the storage 12. When a set upper limit temperature higher than a certain 35 ° C. is detected, the operation of the heater 31 is controlled to be stopped. When the heater 31 is operated, the air sent from the inside of the storage 12 to the temperature control space 16c of the duct passage 16 by the circulation fan 17 is heated by the heater 31. As shown by the arrow of the two-dot chain line in FIG. 4, the heated air is sent to the storage 12 again through the vertical duct passage 16a and the horizontal duct passage 16b, and the inside of the storage 12 is warmed by the heated air. Be done.

Further, the control device 50 not only controls the temperature described above but also controls the humidity in the storage 12 so that the humidity in the storage 12 becomes 85% even in the proof (fermentation) step. When the control device 50 detects the lower limit set humidity whose detection humidity by the humidity sensor 19 is lower than 85%, the humidifier 40 controls to humidify the humidity, and when the control device 50 detects the upper limit set humidity whose detection humidity by the humidity sensor 19 is higher than 85%. It is controlled to stop the humidification by the humidifier 40. When the inside of the storage 12 is humidified by the humidifier 40, the humidity of the storage 12 is controlled so that water is intermittently sprayed from the spray nozzle 41 of the humidifier 40 by alternately repeating the spray time and the standby time. ing. By intermittently spraying water from the spray nozzle 41, the sprayed water can be vaporized in the standby time and sufficiently distributed in the storage 12. Further, in this embodiment, the spraying time from the spray nozzle 41 is set to 2 seconds, and the standby time of the spray nozzle 41 is defined by the temperature and humidity in the storage 12 as shown in FIG. There is. In addition, although the waiting time specified by some temperature and some humidity is shown in FIG. 7 and the waiting time specified by other temperature and humidity is omitted, the waiting time of temperature and humidity not shown is shown. It has a proportional relationship with the waiting time for each temperature and the waiting time for each humidity shown.

Even when humidifying by the humidifier 40 based on the detected humidity of the humidity sensor 19 during the proofing (fermentation) step, the control device 50 is defined by the temperature and humidity in the storage 12 described above. Using the waiting time, the waiting time is derived from the detected temperature of the temperature sensor 18 and the detected humidity of the humidity sensor 19. When the control device 50 detects the lower limit set humidity in which the humidity detected by the humidity sensor 19 is lower than 85%, the water supply valve 42b is opened for 2 seconds, which is the spray time, and water is atomized from the spray nozzle 41 for 2 seconds, which is the spray time. It is controlled to repeatedly execute spraying in a shape and closing the water supply valve 42b at the calculated standby time to wait for spraying water. When water is sprayed from the spray nozzle 41 in the form of a mist, the air sent from the storage 12 to the duct passage 16 by the circulation fan 17 is the water sprayed from the spray nozzle 41 in the vertical duct passage 16a. It is vaporized and humidified, and as shown by the arrow of the two-point chain line in FIG. 4, the humidified air is sent to the storage 12 again through the vertical duct passage 16a and the horizontal duct passage 16b, and the inside of the storage 12 is inside. It is humidified by the humidified air. One hour after starting the proofing (fermentation) process, the control device 50 ends the fermentation program.

In the temperature / humidity control cabinet (humidity control cabinet) 10 configured as described above, when humidifying by the humidifier 40 when executing the preheating step and the proof (fermentation) step, the control device 50 sprays from the spray nozzle 41. The humidity of the storage 12 was controlled by intermittently spraying water by alternately repeating the time and the standby time. The mist-like water sprayed during the spray time is vaporized during the standby time and distributed throughout the storage 12, and then the mist-like water is sprayed again during the spray time, so unnecessary water is sprayed. The humidity inside the storage 12 was large and it became difficult to hunt, and it became easier to adjust the humidity inside the storage 12 to the set humidity.

In the temperature / humidity control cabinet (humidity control cabinet) 10, the control device 50 uses a standby time defined based on both the detection temperature of the temperature sensor 18 and the detection humidity of the humidity sensor 19 to water from the spray nozzle 41. Humidity is controlled in the storage 12 so as to spray. Specifically, the standby time of the spray nozzle 41 is defined by the temperature and humidity in the storage 12 as shown in FIG. 7, and the standby time defined by the temperature and humidity in the storage 12 is used. Therefore, the standby time is derived from the detected temperature of the temperature sensor 18 and the detected humidity of the humidity sensor 19. As can be understood from FIG. 7, the lower the temperature, the more difficult the water vaporizes, so the waiting time is lengthened, and the lower the humidity, the larger the change in humidity due to one spray, so the waiting time is lengthened. In this case, the mist-like water sprayed during the spraying time is vaporized to an appropriate waiting time and distributed in the storage 12, and then the mist-like water is sprayed again during the spraying time. Therefore, it was possible to prevent unnecessary water from being sprayed, the humidity inside the storage 12 was large and it became difficult to hunt, and it became easy to adjust the humidity inside the storage 12 to the set humidity. In this embodiment, the control device 50 is stored so as to spray water from the spray nozzle 41 using a standby time specified based on both the detected temperature of the temperature sensor 18 and the detected humidity of the humidity sensor 19. Although the humidity of the refrigerator 12 is controlled, the present invention is not limited to this, and the control device 50 has a spraying time specified based on both the detected temperature of the temperature sensor 18 and the detected humidity of the humidity sensor 19. The humidity of the storage 12 may be controlled by spraying water from the spray nozzle 41 using the standby time. In this case, the lower the temperature, the more difficult it is for water to vaporize, so the injection time is shortened, and the lower the humidity, the larger the change in humidity due to one spray, so the spray time is shortened.

In this embodiment, the control device 50 sprays water from the spray nozzle 41 using a spray time and a standby time defined based on both the detected temperature of the temperature sensor 18 and the detected humidity of the humidity sensor 19. Although the humidity of the storage 12 is controlled in this manner, the present invention is not limited to this, and the control device 50 has at least one of the spray time and the standby time (spray time and / /) based on the detection temperature of the temperature sensor 18. Alternatively, it may be controlled to change the waiting time). In this case, the lower the detection temperature of the temperature sensor 18, the more difficult it is for water to vaporize, so that the spraying time is shortened and the standby time is lengthened. Similarly, the control device 50 may be controlled to change at least one of the spray time and the standby time (spray time and / or standby time) based on the detected humidity of the humidity sensor 19. In this case, the lower the detected humidity of the humidity sensor 19, the larger the change in humidity due to one spraying, so that the spraying time is shortened and the standby time is lengthened.
