It's getting smaller. Furthermore, the device protrusion 71 is symmetrically inclined with respect to the center line Ob. Therefore, the device protrusion 71 has a tapered shape. Further, the device protrusion 71 is inserted into the plate hole 511 and the box protrusion hole 521. Further, the outer surface of the device protrusion 71 and the inner surface of the box protrusion 52 are in contact with each other. This closes the gap between the outer surface of the device duct 70 and the inner surface of the box duct 50.

The device protrusion hole 711 is surrounded by the device protrusion 71 . Further, the lower side of the device protrusion hole 711 communicates with the inside air recovery hole 313 . Furthermore, the upper side of the device protrusion hole 711 communicates with the inside air supply hole 314 .

The first device partition plate 81 is connected to the upper and lower sides of the device protruding end portion 712 and extends in the vertical direction. Note that the device protruding end 712 is the end of the device protruding portion 71 on the storage chamber 2x side.

The second device partition plate 82 is connected to the left and right sides of the device projecting end 712 and extends in the left-right direction. Further, the second device partition plate 82 is connected to the first device partition plate 81 by penetrating it.

The device recovery hole 73 is divided into a plurality of sections by the lower side of the device protruding end 712, the first device partition plate 81, and the second device partition plate 82. Further, the device recovery hole 73 communicates with the box main recovery hole 55 and the lower side of the device protrusion hole 711 .

The device supply hole 74 is defined by the upper side of the device protruding end portion 712, a first device partition plate 81, and a second device partition plate 82. Further, the device supply hole 74 communicates with the box main supply hole 56 and the upper side of the device protrusion hole 711 .

The deformable member 72 is arranged on the casing rear wall 31b so as to surround the device protrusion 71. Furthermore, the deformable member 72 is in contact with the front surface 211 of the box front wall 21 of the box 2 . As a result, the deformable member 72 receives force from the box 2 and is elastically deformed. Further, in the direction orthogonal to the front surface 211 of the box front wall 21, the length Ls of the deformable member 72 in this deformed state is larger than the distance Lc from the casing rear wall 31b to the box plate part 51. Therefore, the deformable member 72 covers the gap between the casing rear wall 31b and the box plate portion 51.

As shown in FIGS. 7 and 8, the battery 32 is disposed inside the casing 31 on the opposite side of the outside air introduction hole 311. Further, the battery 32 supplies power to an expansion valve 37, an exhaust fan 39, a blow-off fan 40, an inverter 43, and an ECU 46, which will be described later.

The compressor 35, condenser 36, expansion valve 37, and evaporator 38 are connected by piping and constitute a vapor compression type refrigeration cycle.

Further, the compressor 35 is arranged in the machine room 31z of the casing 31 so as to face the outside air introduction hole 311. The compressor 35 also sucks refrigerant from an evaporator 38, which will be described later. Furthermore, the compressor 35 compresses the sucked refrigerant and discharges the high temperature and high pressure refrigerant toward the condenser 36 .

The capacitor 36 is arranged in the heat radiation chamber 31y of the casing 31, as shown in FIGS. 4, 7, and 8. Further, the condenser 36 exchanges heat between the air in the heat radiation chamber 31y and the refrigerant discharged by the compressor 35. Specifically, the air in the heat radiation chamber 31y absorbs heat from the refrigerant discharged by the compressor 35. Further, the refrigerant discharged by the compressor 35 radiates heat to the air in the heat radiation chamber 31y and condenses. Further, the refrigerant condensed by the condenser 36 flows to the expansion valve 37.

The expansion valve 37 reduces the pressure of the refrigerant flowing from the condenser 36. This depressurized refrigerant becomes a low-temperature, low-pressure refrigerant and flows to the evaporator 38 .

The evaporator 38 is arranged in the recovery chamber 31x of the casing 31. Further, the evaporator 38 exchanges heat between the air in the recovery chamber 31x and the refrigerant made low in temperature and pressure by the expansion valve 37. Specifically, the air in the recovery chamber 31x is cooled by dissipating heat to this low-temperature, low-pressure refrigerant. Moreover, this low-temperature, low-pressure refrigerant absorbs heat from the air in the recovery chamber 31x. This heat-absorbed refrigerant is sucked by the compressor 35, as described above, and the refrigerant from the compressor 35 is circulated.

The exhaust fan 39 is arranged in the outside air exhaust hole 312 in the heat radiation chamber 31y of the casing 31. Further, as shown in FIG. 7, the exhaust fan 39 sucks in air that has passed through the compressor 35 and the condenser 36 from outside the casing 31 via the outside air introduction hole 311. At this time, the exhaust fan 39 sucks the air that has absorbed heat by the condenser 36 in the heat radiation chamber 31y. Further, the exhaust fan 39 blows out the sucked air to the outside of the casing 31 through the outside air exhaust hole 312.

As shown in FIG. 4, the blowing fan 40 is disposed within the device protrusion hole 711, facing the inside air supply hole 314. Further, the blow-off fan 40 sucks air cooled by the evaporator 38 through the inside air supply hole 314. Furthermore, the blowing fan 40 blows out this sucked air toward the accommodation chamber 2x of the box 2.

Drain pan 41 is formed into a funnel shape. Further, a portion of the drain pan 41 having a larger diameter is arranged below the evaporator 38 . Thereby, the drain pan 41 receives the condensed water generated and dripped by the evaporator 38 at a portion of the drain pan 41 having a large diameter. Further, a portion of the drain pan 41 having a smaller diameter is inserted into the partition member hole 315. Further, a portion of the drain pan 41 having a smaller diameter extends toward an evaporating dish 42, which will be described later. Therefore, the drain pan 41 guides the received condensed water to the evaporating dish 42.

The evaporating dish 42 is arranged below the condenser 36 and the drain pan 41 in the heat radiation chamber 31y of the casing 31. Further, the evaporating dish 42 receives condensed water dripping from the drain pan 41. The condensed water received by the evaporation plate 42 is evaporated by absorbing heat from the refrigerant flowing through the condenser 36 together with the air in the heat radiation chamber 31y. Therefore, the refrigerant flowing through the condenser 36 radiates heat not only to the air in the heat radiating chamber 31y but also to this condensed water. As a result, the temperature of the refrigerant flowing through the condenser 36 tends to decrease, so that a lower temperature refrigerant flows through the evaporator 38 than when there is no evaporation plate 42 . Therefore, since this low-temperature refrigerant absorbs heat from the air in the recovery chamber 31x, the effect of cooling the air in the recovery chamber 31x is enhanced.

As shown in FIGS. 7 and 8, the inverter 43 is arranged in the machine room 31z of the casing 31 above an ECU 46, which will be described later. Further, the inverter 43 supplies alternating current to the compressor 35 based on a command from the ECU 46. Thereby, the inverter 43 controls the rotation speed of the compressor 35 and the like.

The ECU 46 is arranged above the expansion valve 37 in the machine room 31z of the casing 31. Further, the ECU 46 is a microcomputer including a CPU, RAM, ROM, flash memory, and the like. RAM, ROM, and flash memory are all non-transient physical storage media. A CPU executes a program stored in a ROM or flash memory, using RAM as a work area. By executing the program by the CPU, the ECU 46 controls, for example, the rotation speed of the compressor 35 by controlling the inverter 43.

The temperature adjustment system is configured as described above. This temperature adjustment system cools the object T housed in the box 2.

Next, cooling of the object T by this temperature adjustment system will be explained.

When power from the battery 32 is supplied to the blow-off fan 40, the blow-off fan 40 sucks air cooled by the evaporator 38 through the inside air supply hole 314, as shown in FIG. Furthermore, the blowing fan 40 blows out this sucked air toward the accommodation chamber 2x of the box 2. At this time, air from the blow-off fan 40 flows into the box main supply hole 56 via the upper side of the device protrusion hole 711 and the device supply hole 74. In addition, in FIG. 4, the air flow is schematically represented by a two-dot chain line.

Here, in the direction perpendicular to the front surface 211 of the box front wall 21, if the object T does not block the box main supply hole 56, the air flowing through the box main supply hole 56 flows directly to the storage chamber 2x and , flows into the storage chamber 2x via the box preliminary supply hole 58. As a result, the inside of the storage chamber 2x is cooled, so that the object T is cooled. Further, in the direction orthogonal to the front surface 211 of the box front wall 21, if the object T does not block the box main recovery hole 55, the air in the storage chamber 2x directly flows into the box main recovery hole 55. Moreover, in this case, the air in the storage chamber 2x flows directly to the main recovery hole 55 for boxes, and also flows to the main recovery hole 55 for boxes via the preliminary recovery hole 57 for boxes.

Further, as shown in FIG. 10, when the object T blocks the box main supply hole 56 in the direction perpendicular to the front surface 211 of the box front wall 21, the air flowing through the box main supply hole 56 is It cannot flow directly into chamber 2x. Therefore, the air flowing through the box main supply hole 56 flows into the storage chamber 2x via the box preliminary supply hole 58. As a result, the inside of the storage chamber 2x is cooled, so that the object T is cooled. Furthermore, if the object T blocks the box main recovery hole 55 in the direction perpendicular to the front surface 211 of the box front wall 21, the air in the storage chamber 2x may flow directly into the box main recovery hole 55. Can not. Therefore, in this case, the air in the storage chamber 2x flows to the main box recovery hole 55 via the box preliminary recovery hole 57. In addition, in FIG. 10, the air flow is schematically represented by a two-dot chain line.

Further, as shown in FIGS. 4 and 10, the air flowing through the box main recovery hole 55 passes through the device recovery hole 73, the lower side of the device protrusion hole 711, and the inside air recovery hole 313, and then passes through the recovery chamber 31x. flows to The air flowing through the recovery chamber 31x is cooled by the evaporator 38. The air cooled by the evaporator 38 is sucked into the blowing fan 40 through the inside air supply hole 314. The blowing fan 40 blows out the sucked air toward the storage chamber 2x of the box 2, as described above.

In this way, the temperature regulation system cools the object T housed in the box 2. Further, in this temperature adjustment system, a decrease in the temperature maintenance function of the box 2 is suppressed.

Next, suppression of the decline in the temperature maintenance function will be explained.

As shown in FIG. 4, the inner surface of the box protrusion 52 extends obliquely with respect to the direction perpendicular to the front surface 211 of the box front wall 21. As a result, the cross-sectional area of the box protrusion hole 521 parallel to the front surface 211 of the box front wall 21 extends in the direction from the end of the box protrusion 52 on the plate hole 511 side to the inner surface of the box protrusion 52. It gets smaller as you move towards.

Further, the device protrusion 71 is inserted into the box protrusion hole 521. Further, the outer surface of the device protrusion 71 and the inner surface of the box protrusion 52 are in contact with each other. Thereby, the gap between the outer surface of the device protrusion 71 and the inner surface of the box protrusion 52 is closed. For this reason, leakage of the air supplied from the temperature adjustment device 3 from the storage chamber 2x is suppressed, so that the temperature maintenance function is ensured.

Moreover, the device protrusion 71 extends in the direction along the box protrusion 52. Specifically, the outer surface of the device protrusion 71 is inclined with respect to the direction perpendicular to the front surface 211 of the box front wall 21. Thereby, the outer surface of the device protrusion 71 and the inner surface of the box protrusion 52 face each other in a direction perpendicular to the front surface 211 of the box front wall 21. Therefore, the outer surface of the device protrusion 71 and the inner surface of the box protrusion 52 can be opposed in the direction in which the device protrusion 71 is inserted into the box protrusion hole 521. As a result, even if the outer surface of the device protrusion 71 and the inner surface of the box protrusion 52 are worn, the device protrusion 71 can be attached to the outer surface of the device protrusion 71 when inserted into the box protrusion hole 521. It can be brought into contact with the inner surface of the box protrusion 52. For example, by pushing the device protrusion 71 toward the box protrusion 52 by the size of the gap corresponding to this amount of wear, the device protrusion 71 is moved between the outer surface of the device protrusion 71 and the box protrusion. 52 can be brought into contact with the inner surface. Therefore, even if the device protrusion 71 and the box protrusion 52 are worn out, the gap between the outer surface of the device protrusion 71 and the inner surface of the box protrusion 52 can be closed. Therefore, deterioration of the temperature maintenance function of the box 2 is suppressed.

Moreover, this temperature adjustment system also has the following effects.

[1] Since the inner surface of the device protrusion 71 and the outer surface of the box protrusion 52 are inclined with respect to the direction perpendicular to the front surface 211 of the box front wall 21, the device protrusion 71 is inserted into the box protrusion hole. 521 is inclined with respect to the direction of insertion. As a result, when the temperature adjustment device 3 is attached to the box 2, the force applied to the device protrusion 71 and the box protrusion 52 is dispersed, so that the device protrusion 71 and the box protrusion 52 are tilted. It will be smaller compared to when it is not. Therefore, wear of the device protrusion 71 and the box protrusion 52 is suppressed. Therefore, since deterioration of the device protrusion 71 and the box protrusion 52 is suppressed, the gap between the outer surface of the device protrusion 71 and the inner surface of the box protrusion 52 is suppressed from increasing. Therefore, deterioration of the temperature maintenance function of the box 2 is suppressed.

Further, the inner surface of the device protrusion 71 and the outer surface of the box protrusion 52 are inclined with respect to the direction in which the device protrusion 71 is removed from the box protrusion hole 521. As a result, while the device protrusion 71 is inserted into the box protrusion hole 521, a force is applied to the device protrusion 71 in the direction of removing the device protrusion 71 from the box protrusion hole 521. Therefore, when removing the temperature adjustment device 3 from the box 2, the force applied to the device protrusion 71 and the box protrusion 52 is compared to when the device protrusion 71 and the box protrusion 52 are not inclined. It can be made smaller. Therefore, similarly to the above, wear of the device protrusion 71 and the box protrusion 52 is suppressed. Thereby, deterioration of the device protrusion 71 and the box protrusion 52 is suppressed, and the gap between the outer surface of the device protrusion 71 and the inner surface of the box protrusion 52 is suppressed from increasing. Therefore, deterioration of the temperature maintenance function of the box 2 is suppressed.

[2] As described above, when the temperature adjustment device 3 is attached to the box 2, the force applied to the device protrusion 71 and the box protrusion 52 is dispersed, and therefore becomes relatively small. Further, when removing the temperature adjustment device 3 from the box 2, the force applied to the device protrusion 71 and the box protrusion 52 becomes relatively small. Therefore, it becomes easy to attach the temperature adjustment device 3 to the box 2 and to remove the temperature adjustment device 3 from the box 2.

[3] As described above, since the deterioration of the device protrusion 71 and the box protrusion 52 is suppressed, the durability of the device protrusion 71 and the box protrusion 52 is improved.

[4] The box duct 50 and the device duct 70 are made of resin. Thereby, the dimensional accuracy of the box duct 50 and the device duct 70 can be made relatively high. Therefore, the device protrusion 71 can be easily inserted into the box protrusion 52, and the outer surface of the device protrusion 71 and the inner surface of the box protrusion 52 can easily come into contact with each other. Therefore, the gap between the outer surface of the device protrusion 71 and the inner surface of the box protrusion 52 is easily closed. Therefore, leakage of the air supplied from the temperature adjustment device 3 from the storage chamber 2x is suppressed, so that the temperature maintenance function is improved.

[5] The deformable member 72 is arranged on the casing rear wall 31b and comes into contact with the front surface 211 of the box front wall 21 of the box 2. As a result, the deformable member 72 receives force from the box 2 and deforms. By deforming the deforming member 72, the position of the device protrusion 71 when inserted into the plate hole 511 and the box protrusion hole 521 can be adjusted.

[6] Moreover, the deformable member 72 covers the gap between the casing rear wall 31b and the box plate part 51. This prevents the air in the storage chamber 2x from leaking to the outside of the box 2 via the small gap between the outer surface of the device protrusion 71 and the inner surface of the box protrusion 52. Further, this leakage suppresses the occurrence of dew condensation due to condensation of water vapor contained in the air outside the box 2.

[7] The box duct 50 has a box preliminary recovery hole 57 and a box preliminary supply hole 58 in addition to the box main recovery hole 55 and the box main supply hole 56.

The box preliminary recovery hole 57 communicates with the box main recovery hole 55 and the storage chamber 2x in a direction perpendicular to the front surface 211 of the box front wall 21.

As a result, as shown in FIG. 10, even if the object T blocks the main collection hole 55 for boxes, the air in the storage chamber 2 It flows into the main recovery hole 55 and is recovered.

Further, the box preliminary supply hole 58 communicates with the box main supply hole 56 and the storage chamber 2x in a direction perpendicular to a direction perpendicular to the front surface 211 of the box front wall 21.

As a result, as shown in FIG. 10, even if the object T blocks the main supply hole 56 for the box, the air from the blow-off fan 40 passes through the preliminary supply hole 58 for the box to the storage chamber. Flows to 2x. Therefore, even in this case, the inside of the storage chamber 2x is cooled, so the object T is cooled.

[8] The box duct 50 has a first extension part 531, a second extension part 532, a third extension part 533, and a fourth extension part 534. Each of the first extension part 531, the second extension part 532, the third extension part 533, and the fourth extension part 534 protrudes from the outer shell hole 210 toward the inside of the storage chamber 2x, and also extends from the box front wall 21. It is located inside the storage chamber 2x with respect to the rear surface 212. As a result, the object T is blocked by the first extension part 531, the second extension part 532, the third extension part 533, and the fourth extension part 534, so that it becomes difficult to contact the rear surface 212 of the box front wall 21. Therefore, the storage chamber 2x is prevented from being blocked by the object T.

(Second embodiment)
In the second embodiment, the temperature adjustment system heats or cools the inside of the storage chamber 2x.

The temperature adjustment device 3 includes the above-described casing 31, device duct 70, deformable member 72, battery 32, compressor 35, condenser 36, and expansion valve 37. The temperature adjustment device 3 also includes an evaporator 38, an exhaust fan 39, a blowing fan 40, a drain pan 41, an evaporating dish 42, an inverter 43, and an ECU 46. Furthermore, the temperature adjustment device 3 includes a heater 47 in addition to these.

The heater 47 is arranged between the evaporator 38 and the blowing fan 40, as shown in FIG. Further, the heater 47 generates heat using electric power from the battery 32 . Furthermore, the heater 47 generates heat based on a command from the ECU 46. Thereby, the heater 47 heats the air that has passed through the evaporator 38.

The second embodiment is configured as described above.

Next, heating of the object T by this temperature adjustment system will be explained.

When power from the battery 32 is supplied to the heater 47, the heater 47 heats the air that has passed through the evaporator 38. Further, when power from the battery 32 is supplied to the blow-off fan 40, the blow-off fan 40 sucks air heated by the heater 47 through the inside air supply hole 314, as shown in FIG. Furthermore, the blowing fan 40 blows out this sucked air toward the accommodation chamber 2x of the box 2. Air from the blow-off fan 40 flows into the box main supply hole 56 via the device protrusion hole 711 and the device supply hole 74.

Here, in the direction perpendicular to the front surface 211 of the box front wall 21, if the object T does not block the box main supply hole 56, the air flowing through the box main supply hole 56 flows directly to the storage chamber 2x and , flows into the storage chamber 2x via the box preliminary supply hole 58. As a result, the inside of the storage chamber 2x is heated, so that the object T is heated. Further, in the direction orthogonal to the front surface 211 of the box front wall 21, if the object T does not block the box main recovery hole 55, the air in the storage chamber 2x directly flows into the box main recovery hole 55. Moreover, in this case, the air in the storage chamber 2x flows directly to the main recovery hole 55 for boxes, and also flows to the main recovery hole 55 for boxes via the preliminary recovery hole 57 for boxes.

Furthermore, if the object T blocks the box main supply hole 56 in the direction perpendicular to the front surface 211 of the box front wall 21, the air flowing through the box main supply hole 56 will not flow directly into the storage chamber 2x. Can not. Therefore, in this case, the air flowing through the box main supply hole 56 flows into the storage chamber 2x via the box preliminary supply hole 58. As a result, the inside of the storage chamber 2x is heated, so that the object T is heated. Furthermore, if the object T blocks the box main recovery hole 55 in the direction perpendicular to the front surface 211 of the box front wall 21, the air in the storage chamber 2x cannot flow directly into the box main recovery hole 55. Can not. Therefore, in this case, the air in the storage chamber 2x flows to the main box recovery hole 55 via the box preliminary recovery hole 57.

The air flowing through the box main recovery hole 55 flows into the recovery chamber 31x via the device recovery hole 73, the lower side of the device protrusion hole 711, and the inside air recovery hole 313. The air flowing through the recovery chamber 31x is heated by the heater 47. The air heated by the heater 47 is sucked into the blowing fan 40 via the inside air supply hole 314. The blowing fan 40 blows out the sucked air toward the storage chamber 2x of the box 2, as described above.

As described above, the object T is heated by the temperature adjustment system. Note that the object T is cooled by this temperature adjustment system without power being supplied from the battery 32 to the heater 47, and as in the first embodiment, the blowing fan 40 sucks in air cooled by the evaporator 38. This is done by blowing out the air towards the storage chamber 2x of the box 2. Further, when precisely adjusting the temperature and humidity of the object T, the air flowing through the collection chamber 31x is cooled and dehumidified by the evaporator 38, and the temperature and humidity are adjusted. The air cooled by the evaporator 38 is heated by a heater 47 and its temperature is adjusted. The air heated by the heater 47 is sucked into the blowing fan 40 via the inside air supply hole 314. The blowing fan 40 blows out the sucked air toward the storage chamber 2x of the box 2, as described above. Thereby, in addition to temperature adjustment of the target object T, humidity adjustment of the target object T is performed.

The second embodiment also provides the same effects as the first embodiment.

(Third embodiment)
In the third embodiment, the form of the device duct 70 is different. In the first embodiment, the device protrusion 71 of the device duct 70 is integrally connected to the casing rear wall 31b. In contrast, in the third embodiment, the device protrusion 71 of the device duct 70 is connected to the casing rear wall 31b separately. Other than this, the second embodiment is the same as the first embodiment.

In addition to the above-described device protrusion hole 711, device protrusion 71, first device partition plate 81, second device partition plate 82, device recovery hole 73, and device supply hole 74, the device duct 70 has the following features: , a device plate portion 75, a connecting member 76, and a non-connecting portion 77.

The device plate portion 75 corresponds to the device base, and is formed into a plate shape as shown in FIGS. 12 and 13. Further, the device plate portion 75 is connected to the device protrusion 71 and extends in a direction parallel to the front surface 211 of the box front wall 21 . Note that the device plate portion 75 may extend in a direction perpendicular to the front surface 211 of the box front wall 21 .

Furthermore, here, a deformable member 72 is arranged on the device plate portion 75. This deformable member 72 is in contact with the front surface 211 of the box front wall 21 of the box 2 . As a result, the deformable member 72 receives force from the box 2 and is elastically deformed. Further, in the direction orthogonal to the front surface 211 of the box front wall 21, the length Ls of the deformable member 72 in this deformed state is larger than the distance Lp from the device plate part 75 to the box plate part 51. Thereby, the deformable member 72 covers the gap between the device plate part 75 and the box plate part 51.

The connecting member 76 is made of adhesive or the like and is connected to the casing rear wall 31b and the front side of the device plate portion 75. Thereby, the device plate portion 75 is connected to the casing rear wall 31b via this connecting member 76. In addition, in FIGS. 12 and 13, in order to clarify the location of the connecting member 76, the connecting member 76 is shown in an exaggerated dot pattern.

The non-connection portion 77 is a gap formed between the casing rear wall 31b and the device plate portion 75, which face each other in a direction orthogonal to the front surface 211 of the box front wall 21.

The third embodiment is configured as described above. The third embodiment also provides the same effects as the first embodiment. Further, in the third embodiment, the device plate portion 75 is connected to the casing rear wall 31b via the connecting member 76, and there is a non-connected portion between the casing rear wall 31b and the device plate portion 75. 77 are arranged. This makes it easy to remove the device plate portion 75 from the casing rear wall 31b starting from the non-connection portion 77.

(Fourth embodiment)
In the fourth embodiment, the form of the box duct 50 is different. Other than this, the second embodiment is the same as the first embodiment.

The box duct 50 further includes a preliminary recovery hole 571 and a preliminary supply hole 581, as shown in FIGS. 14 and 15.

Here, a part of the box protrusion 52 protrudes from the outer shell hole 210 toward the inside of the storage chamber 2x. Therefore, a part of the box protrusion 52 is located inside the storage chamber 2x with respect to the rear surface 212 of the box front wall 21.

The preliminary recovery hole 571 is formed on the lower side of the box protrusion 52 on the storage chamber 2x side. The preliminary recovery hole 571 corresponds to the box preliminary recovery hole 57 described above, and the lower side of the box protrusion hole 521 extends in a direction perpendicular to the front surface 211 of the box front wall 21. It communicates with the storage chamber 2x.

As a result, even if the object T blocks the box main collection hole 55 in the direction perpendicular to the front surface 211 of the box front wall 21, the air in the storage chamber 2x passes through the preliminary collection hole 571. It flows into the box protrusion hole 521 and is collected.

The preliminary supply hole 581 is formed above the box protrusion 52, as shown in FIG. Further, the preliminary supply hole 581 corresponds to the above-mentioned preliminary supply hole 58 for the box, and is accommodated with the upper side of the protrusion hole 521 for the box in the direction perpendicular to the front surface 211 of the box front wall 21. It communicates with room 2x.

As a result, even if the object T blocks the box main supply hole 56 in the direction perpendicular to the front surface 211 of the box front wall 21, the air from the blowing fan 40 passes through the preliminary supply hole 581. and flows into the storage chamber 2x. Therefore, the inside of the storage chamber 2x is cooled, so that the object T is cooled.
