As shown in FIG. 3, the three heaters 46 are held by heater brackets 47 extending in the left-right direction and arranged in the front-rear direction, and attached to the lower side of the evaporator 40 . That is, the heating device 21 efficiently heats the air with radiant heat and also functions as a defrost heater for the evaporator 40 arranged above.

Furthermore, a part of the humidifying device 22 is accommodated in the functional component chamber 30 . The humidifying device 22 includes a spray nozzle 50 that is a two-fluid nozzle that sprays water in the form of a mist, a water supply pipe 51 that supplies water from a water supply source to the spray nozzle 50, and an air supply pipe 52 that supplies air to the spray nozzle 50. , and an air pump 53 for sending air under pressure to the spray nozzle 50 through the air supply pipe 52 . The water supply pipe 51 is provided with a water supply valve 51a. A water discharge pipe 54 is connected from the water supply valve 51a to the spray nozzle 50 side, and the water discharge pipe 54 is provided with a water discharge valve 54a. Also, the air pump 53 is configured to supply the air sucked from the functional component chamber 30 to the spray nozzle 50 .

The spray nozzle 50, although detailed illustration and description is omitted, has two cylinders, and the inner cylinder has a water ejection port at the tip of the outer cylinder. An air ejection port is provided at the tip. The air jetting port is positioned behind the water jetting port, and by jetting air from behind the jetted water, the water is atomized in front of the spray nozzle 50. do. As shown in FIG. 3, the tip of the spray nozzle 50 is attached to the lower side of the heating device 21 so as to face the inside of the functional component chamber 30 from the side surface.

Then, the humidifying device 22 opens the water supply valve 51 a , operates the air pump 53 , and sprays misty water from the spray nozzle 50 . Thereby, the air sent out from the circulation fan 36 is humidified, and the humidity in the storage room 14 is increased. The humidifying device 22 opens the drain valve 54a and drains the water from the drain pipe 54 so that no water remains in the water supply pipe 51 when the water is not sprayed from the spray nozzle 50. .

The main temperature/humidity control cabinet 10 configured as described above is controlled by the control device 24 . Specifically, the control device 24 controls the circulation fan 36, the cooling device 20, the heating device 21, and the humidifying device 22 so as to independently adjust the temperature and humidity of each of the storage chambers 14A and 14B. is configured to In addition, the functional component room 30 houses a temperature sensor 60 and a humidity sensor 61 (see FIG. 7). , 14B to regulate the temperature and humidity.

<Configuration of circulation path>
Here, the air flow inside the storage chamber 14 will be described in detail. As described above, the temperature/humidity control chamber 10 is partitioned into the storage chamber 14 and the functional component chamber 30 by the back panel 32, and the air intake path 37 formed by the top panel 33 leads to the storage chamber 14. of air is sucked in, and temperature- and humidity-controlled air is discharged into the storage chamber 14 from a discharge passage 38 formed by the bottom panel 34 . As shown in FIGS. 3 and 6, a side wall duct member 65 extending vertically is fixed to each of the left and right side walls in each space 12 in the middle of the storage chamber 14 in the front-to-rear direction. The side wall side duct member 65 has a U-shaped cross section and forms a side wall side circulation path 66 between the side wall side duct member 65 and the side surface of the space 12 . Further, the side wall duct member 65 is formed with a discharge port 67 for discharging air onto the tray on the upper side. Then, after attaching the four shelf posts 17 and the side wall side duct members 65 to the side walls of the temperature/humidity control cabinet 10 in the state shown in FIG. A circulation path in the space 12 is formed by attaching in order of 34 .

Air circulates as indicated by white arrows in FIG. Specifically, when the circulation fan 36 operates, the air in the storage chamber 14 is sucked into the functional component chamber 30 . From there, it will be sucked in. That is, the opening serves as a suction port 70 for taking in the air in the storage chamber 14 into the suction path 37 .

On the other hand, the temperature and humidity in the functional component room 30 are adjusted, and the air that has flowed under the bottom panel 34 is discharged into the storage room 14 through the openings on both sides of the bottom panel 34 (both sides in the left-right direction). be Since the front end of the bottom panel 34 is closed, the forward air flow is blocked and the air is discharged only from the sides of the bottom panel 34 . Then, as shown in FIG. 6, part of the exhaled air rises upward through the gap between the tray guide 16 and the side wall and flows onto each tray. Another part of the discharged air enters the side wall circulation path 66 formed by the side wall duct member 65 and is discharged onto the upper trays. Further, another part of the air is also discharged forward from the lateral front ends of the bottom panel 34 and flows into the storage chamber 14 on the front side. Then, the air that has flowed into the front side of the storage chamber 14 passes through the gaps between the plurality of trays and the opening/closing door 15, flows onto each tray from the front, and advances toward the suction port 70 at the upper end. It's becoming

<Structure of lighting device>
Further, the temperature/humidity control cabinet 10 is provided with lighting devices 80 for illuminating the interiors of the two storage rooms 14A and 14B corresponding to the two storage rooms 14A and 14B, respectively. Each lighting device 80 is attached to the front end of the inner side of the space 12 of the housing 11, as shown in FIGS. As shown in FIG. 9 , each lighting device 80 includes a long LED lamp 81 (hereinafter sometimes simply referred to as “LED 81 ”) as a light source, and an LED base for fixing the LED 81 inside the housing 11 . It is configured including a base 82 and a cover 83 that covers the LED 81 . As shown in FIG. 8, the illumination device 80 is attached to the housing 11 so as to extend vertically. Specifically, the LED 81 and the LED base 82 are fixed to the housing 11 by screws (not shown) using mounting holes 81a and 82a provided at the upper and lower ends, and the cover 83 is attached to the LEDs 81. and the LED base 82, it is fixed to the housing 11 with a screw (not shown) using a mounting hole 83b provided in a bracket 83a of the cover 83. As shown in FIG.

An LED wiring 84 is connected to the upper end of the LED 81. The LED wiring 84 extends from the upper end of the cover 83 and is fixed to the upper end of the inner side surface of the space 12 so as to extend in the vertical direction. It extends through the wiring cover 85 to the functional component chamber 30 and is connected to other wiring.

As shown in FIGS. 9 to 11, the cover 83 includes a cover body 90 having a rectangular opening 90a and a diffusion plate 91 fixed inside the cover body 90 so as to cover the opening 90a. and consists of The diffuser plate 91 is made of highly translucent acrylic resin and diffuses the light from the LEDs 81 into the storage chamber 14 while covering the LEDs 81 . On the other hand, the cover body 90 and the LED base 82 are made of stainless steel. The diffuser plate 91 is fixed to the cover body 90 with one rivet 92, and is fixed at a single mounting portion. More specifically, the cover body 90 is provided with a mounting hole 90b on the upper side of the opening 90a, and the diffusion plate 91 is provided with a mounting hole 91a at the upper end. The diffuser plate 91 is fixed to the cover main body 90 by caulking the tip while the diffuser plate 91 is inserted through the hole 90b and the attachment hole 91a of the diffuser plate 91 .

Since the temperature/humidity control chamber 10 manages the bread dough from freezing to fermentation, the temperature change in the storage chamber 14 is large, and since it may be humidified, the air flow in the storage chamber 14 is small. Condensation may occur at some points. Then, for example, if the lighting device is arranged on the back side of the storage room 14, there is a risk that the LEDs will be exposed to light. On the other hand, in the temperature/humidity control cabinet 10 , the lighting device 80 is arranged on the front end side of the storage room 14 . On the other hand, in the temperature/humidity control chamber 10, on the front end side of the storage chamber 14, air flows from below toward the suction port 70 provided at the upper end, as described above. That is, as shown in FIG. 8, the lighting device 80 is arranged along the flow of air (white arrow in FIG. 8), and the flow of air hits the lighting device 80. Dew condensation on the surface of the cover 83 and dew on the LED 81 can be suppressed. In addition, since the lighting device 80 related to the temperature/humidity control cabinet 10 is arranged at the front end of the storage room 14, it is easy to clean even if it becomes dirty. Even if it occurs, it is possible to easily perform the work.

Since the cover body 90 of the lighting device 80 is made of stainless steel and the diffusion plate 91 is made of acrylic, the expansion coefficients of the lighting device 80 and the storage chamber 14 are different due to temperature changes. Specifically, the coefficient of expansion of the diffusion plate 91 made of acrylic is greater than the coefficient of expansion of the cover body 90 made of stainless steel. In other words, if the diffusion plate is fixed to the cover main body at a plurality of mounting portions, the diffusion plate may be damaged due to the difference in the amount of deformation caused by the temperature change. On the other hand, in the lighting device 80 related to the temperature/humidity control cabinet 10, the diffuser plate 91 is fixed to the cover main body 90 at one point on the upper end. The deformation is allowed on the lower end side, so that a situation in which the diffusion plate 91 is damaged can be avoided.
