This female connector portion 143a is formed with a terminal portion 143b extending toward the damper portion 142 side, and is performed by inserting a male connector (not shown) into the female connector portion 143a from below in the vertical direction. Electrical connection. In addition, the damper member 140 is attached to the fan casing 111 (refer to FIG. 4 ), and is arranged so that the damper portion 141 is positioned on the upper side in the vertical direction and the damper portion 142 is positioned on the lower side in the vertical direction. , the female connector portion 143a is disposed facing downward. Therefore, even if the drain water when the frost generated at the damper member 140 dissolves, flows down on the casing of the driving part 143, for example, the terminal part 143b can be prevented from being exposed to the drain water.

Fig. 11 is a sectional view showing the arrangement of the damper member. In the damper member 120, in the arrangement shown in FIG. 11(a), the water W is likely to accumulate on the inner wall surface of the lower portion of the valve box 122a of the flap support portion 122. If the water W freezes at such a position, there is a possibility that the flapper 121 will be stuck by ice and cannot be opened. Therefore, as shown in FIG. 11( b ), by configuring the damper member 120 to incline the valve box 122 a so as to descend toward the rear side, it is possible to prevent the accumulation of the water W in the flap support portion 122 side situation. In addition, the damper members 130 and 140 are similarly arranged to be inclined.

Moreover, when the damper member 120 is comprised in the arrangement shown in FIG.11(b), the water system will accumulate in the recessed part formed by the valve seat part 122c and the flapper 121. However, since a heater H6 (refer to FIG. 9 ), which will be described later, is provided in the damper member 120 , when the shutter 121 is opened, the water system flows to the rear side.

Moreover, it can also be comprised so that the resin material of the damper member 120 may be comprised with the resin provided with water repellency or the resin provided with hydrophilicity.

FIG. 12 is a schematic diagram for explaining the flow of cold air in the refrigerator of the present embodiment. As shown in FIG. 12, in the refrigerating chamber 30 of the refrigerator 1, the cold air generated by the cooler 80B provided exclusively for the refrigerating chamber 30 is sucked into the blower fan 91, and is discharged from A plurality of discharge ports (not shown) in the back of the refrigerator compartment 30 are used to discharge. The cold air after cooling the food is returned to the cooler 80B from a return port (not shown) provided in the lower part of the refrigerator compartment 30 .

In the ice making compartment 40 and the freezing compartment 50 of the refrigerator 1, the cold air generated by the cooler 80A is sent from the outlet 40a provided in the ice making compartment 40 by the blower fan 90 (refer to FIG. 3 ) And it is provided in the discharge port 50a (refer FIG. 3) of the freezer compartment 50, and is discharged. Then, the air after cooling the food is sucked into the return port 41a provided on the back side of the freezer compartment 50, and returns to the cooler 80A through the return flow path 41b. In this way, the ice making compartment 40 and the freezing compartment 50 are constantly supplied with the cold air generated by the cooler 80A.

When the upper-stage switching chamber 60 is set to the freezing temperature zone, the damper member 120 is opened. In this case, the cool air generated by the cooler 80A passes through the damper member 120 . On the other hand, the cold air is directly supplied to the food in the upper storage container 61 from the discharge port 63a provided in the upper switching chamber 60, and directly supplied to the food in the lower storage container 62 from the discharge port 63b.

Moreover, when the upper stage switching chamber 60 is set to the refrigeration temperature zone, the damper part 141 of the damper member 140 is opened. In this case, the cool air generated by the cooler 80A passes through the damper portion 141 . Then, the food system is indirectly cooled by allowing cool air to flow outside the upper storage container 61 and the lower storage container 62 from the discharge port 63c provided in the upper switching chamber 60 . Thereby, drying of the food in the upper storage container 61 and the lower storage container 62 can be suppressed.

When the lower switching chamber 70 is set to the freezing temperature zone, the cool air generated by the cooler 80A passes through the damper member 130 . On the other hand, the cool air is directly supplied to the food in the upper storage container 71 from the discharge port 73a provided in the lower switching chamber 70, and directly supplied to the food in the lower storage container 72 from the discharge port 73b.

In addition, when the lower-stage switching chamber 70 is set to the refrigeration temperature zone, the damper part 142 of the damper member 140 is opened. In this case, the cool air generated by the cooler 80A passes through the damper portion 142 and the flow path 116 (refer to FIG. 4 ). Then, the food system is indirectly cooled by allowing cool air to flow outside the upper storage container 71 and the lower storage container 72 from the discharge port 73c provided in the lower switching chamber 70 . Thereby, drying of the food in the upper storage container 71 and the lower storage container 72 can be suppressed.

In this way, in the refrigerator 1 of the first embodiment, the upper switching chamber 60 can be set to the refrigeration temperature zone, and the lower switching chamber 70 can be set to the freezing temperature zone. Moreover, in the refrigerator 1, the upper switching chamber 60 can be set as a freezing temperature zone, and the lower switching chamber 70 can be set as a refrigeration temperature zone. Moreover, in the refrigerator 1, both the upper stage switching chamber 60 and the lower stage switching chamber 70 can be set as a freezing temperature range. Moreover, in the refrigerator 1, both the upper stage switching chamber 60 and the lower stage switching chamber 70 can be set as a refrigeration temperature range.

Fig. 13(a) is a cross-sectional view showing a refrigerator having a centrifugal fan as the blower fan of the first embodiment, and Fig. 13(b) is a comparative example with a propeller as the blower fan A cross-sectional view of a refrigerator with a fan for display. As shown in FIG. 13( a ), the refrigerator 1 includes a centrifugal fan (a turbo fan or a multi-blade fan) as the blower fan 90 , and the blower fan 90 is arranged behind the rear heat insulating partition member 65 place. This type of blower fan 90 sucks in the cold air from the center side in the radial direction and discharges the cool air in the circumferential direction, so the space in front of the blower fan 90 in the axial direction can be narrowed, and it is only necessary to ensure that there is a shaft. The space behind the direction (suction side) is sufficient. Therefore, in the first embodiment, the dimension D1 in the front-rear direction of the cooler accommodating space 100 provided on the back side of the upper-stage switching chamber 60 can be reduced.

On the other hand, the refrigerator 200 shown as a comparative example in FIG.13(b) is equipped with a propeller fan as the blower fan 201, and the blower fan 201 is arrange|positioned behind the back surface insulation partition member 202. In this case, the blower fan 201 is arranged obliquely, and the suction space and the discharge space are required at the rear and the front, respectively. Therefore, it is necessary to ensure that the dimension D100 (>D1) in the front-rear direction of the space of the cooling flow path provided on the back side of the upper-stage switching chamber 203 is large.

As described above, in the first embodiment, the volume Q1 of the upper-stage switching chamber 60 when the blower fan 90 is used can be compared to the upper stage when the blower fan 201 is used as a comparative example. The volume Q100 of the switching chamber 203 is further ensured. Thereby, it becomes possible to increase the storage capacity of the food in the upper switching chamber 60 .

Moreover, by dividing into the cooler 80B for the refrigerator compartment 30 and the cooler 80A below the refrigerator compartment 30, the cooler 80A can be made small (for example, 7 stages→5 stages). Thereby, the size of the cooler accommodating space 100 in the vertical direction can be made compact. Therefore, the protruding volumes in the ice making compartment 40 and the back surface in the freezing compartment 50 toward the front can be reduced, and the volumes in the ice making compartment 40 and the freezing compartment 50 can be enlarged.

In addition, the blower fan 90 is provided on the upper projection of the cooler 80A, and at least a part of the damper member 120 (refer to FIG. 6 ) is present on the upper projection of the blower fan 90 . Furthermore, the axial direction of the blower fan 90 and the front-rear direction of the opening 122b of the damper member 120 are arranged to be slightly parallel. Therefore, the cold air blown from the blower fan 90 to the centrifugal direction contacts the flapper 121 in the open state of the damper member 120 and is blown to the upper stage switching chamber 60 located on the front side of the opening 122b. Further, the support portion 92b of the blower fan 90 or the surface of the holding panel 67 facing the support portion 92b (refer to FIG. 20 ), the front portion provided at the opening 122b of the damper member 120, and the vacuum heat insulating material V11 or The holding panel 67 facing the back surface of the vacuum heat insulating material V11 is arranged in a slightly parallel manner. By doing so, the dimensions in the front and rear directions of the cooler storage space 100 and the air supply path for guiding the air supply from the air supply fan 90 can be made compact, and the volume of the upper switching chamber 60 can be ensured to be large. .

Fig. 14 is an exploded perspective view showing the insulating partition member. As shown in FIG. 14, the heat insulating partition member 16 includes a synthetic resin case 160 formed of a lower case 161 and an upper case 162, and expanded polystyrene (so-called foamed polystyrene) as a heat insulating material. Styrene) 163, and a vacuum heat insulating material V9 as another heat insulating material are constituted. In addition, since the heat insulating partition member 17 has the same structure as that of the heat insulating partition member 16 , only the heat insulating partition member 16 will be described below.

The lower case 161 is formed in a rectangular shape, and has a side surface portion 161a on which the outer peripheral edge portion is erected. This side part 161a is formed in the whole of four sides. Moreover, the lower case 161 is fastened on the side facing the outer surface of the side surface portion 161a, and locking claws 161b and 161b are formed.

The upper case 162 is formed in a rectangular shape, and has a side surface portion 162 a extending toward the lower case 161 with an outer peripheral edge portion thereof. This side part 162a is formed in the whole of four sides. In addition, the upper case 162 is fastened on the side facing the outer surface of the side surface portion 162a, and a locking hole 162b for engaging the locking claw 161b is formed.

The expanded polystyrene 163 is in the shape of a rectangle fitted into the lower case 161 . Moreover, the thickness of the expanded polystyrene 163 is formed to be lower than the height of the side surface part 161a.

The vacuum heat insulating material V9 is constructed in the same manner as the vacuum heat insulating materials V1 to V8 described above, and is formed in a rectangular shape accommodated in the lower case 161 . In addition, when the vacuum heat insulating material V9 is accommodated in the lower case 161 together with the expanded polystyrene 163, the surface of the vacuum heat insulating material V9 is set to a general thickness at the upper end of the side surface portion 161a.

Moreover, the sealing material 164 is stuck to the side surface of the vacuum heat insulating material V9. The sealing material 164 is formed on the entire outer peripheral surface of the vacuum heat insulating material V9. By providing the sealing material 164, the gap between the lower case 161 and the outer peripheral surface of the vacuum heat insulating material V9 can be filled, and the vacuum heat insulating material V9 can be prevented from moving and being damaged in the lower case 161.

In such a heat insulating partition member 16, after the expanded polystyrene 163 and the vacuum heat insulating material V9 are accommodated in the lower case 161, the upper case 162 is covered. In this case, the side surface portion 162a of the upper case 162 is located at the outer side of the side surface portion 161a of the lower case 161 . Therefore, when the upper case 162 is covered on the lower case 161, since the side portion 162a does not come into contact with the vacuum heat insulating material V9, the vacuum heat insulating material can be prevented from being damaged.

Moreover, on the inner surface of the upper case 162, a double-sided tape 162c is provided. By adhering the upper case 162 and the vacuum heat insulating material V9 with the double-sided tape 162c, it is possible to prevent the upper case 162 from being peeled off from the lower case 161. In addition, the double-sided tape 162c can suppress the formation of voids (spaces) between the upper case 162 and the vacuum heat insulating material V9, and can suppress the occurrence of frost or dew in the voids. .

In addition, in the present embodiment, the case where the lower case 161 and the upper case 162 are fixed by fitting the locking claws 161b into the locking holes 162b has been described as an example and explained. However, it is not limited to such a configuration, and the lower case 161 and the upper case 162 may be fixed with screws.

Fig. 15 is a cross-sectional view showing the installation state of the insulating partition member. As shown in FIG. 15 , when the insulating partition member 16 is installed, a partition wall 18 is provided at the upper side of the insulating partition member 16 to partition the ice making compartment 40 and the freezing compartment 50 on the left and right. Therefore, the insulating partition member 16 cannot be attached from the upper side, but is attached from the lower side of the partition wall 18 .

In addition, ribs 11e integrally formed with the inner box 11 are protrudingly formed on the left and right side surfaces of the inner box 11, and a hard urethane molding is filled in the inner side (rear side) to ensure thermal insulation. From the lower side of the rib 11e, the upper surface of the end portion of the heat insulating partition member 16 is pressed and abutted for positioning, and the lower surface of the end portion of the heat insulating partition member 16 is formed by other members from the lower side. The fixing member 11f is pressed against each other. On the other hand, the fixing member 11f is fixed to the inner case 11 in a state where the insulating partition member 16 is sandwiched by the rib 11e and the fixing member 11f.

In addition, the vacuum heat insulating material V9 is liable to have variations in the external dimensions during manufacture, and a difference occurs between the largest vacuum heat insulating material and the smallest vacuum heat insulating material. Due to the size of such a difference, there is a possibility that heat insulation cannot be performed, and in this case, frost may be generated at the end of the switching chamber (in the case of a refrigerating temperature compartment). Therefore, the urethane (hard urethane molding) front end P2 of the rib 11e is located inside the left-right direction (width direction) ( inside). In other words, the end portion of the vacuum heat insulating material V9 and the rib 11e filled with urethane are arranged so as to overlap in the up-down direction. By setting such a configuration, between the upper switching chamber 60 and the ice making chamber 40 at the left end and between the upper switching chamber 60 and the freezing chamber 50 at the right end, it is possible to prevent the risk of not being thermally insulated. to suppress.

Furthermore, when the insulating partition member 17 partitioning the upper switching chamber 60 and the lower switching chamber 70 is installed, only the upper switching chamber 60 exists above the insulating partition member 17 . Therefore, contrary to the heat insulating partition member 16, the heat insulating partition member 17 can be attached from the upper side. The heat insulating partition members 17 are fixed to ribs 11g formed on the left and right side surfaces of the inner case 11 .

The same is true for the heat insulating partition member 17 , the urethane (hard urethane molding) front end of the rib 11 g is compared to the position (outer peripheral end portion P1 ) where the size of the vacuum heat insulating material V10 (refer to FIG. 2 ) becomes the smallest. The portion P2 is located inside (inward) in the left-right direction (width direction). In other words, the end portion of the vacuum heat insulating material V10 and the rib 11g filled with urethane are arranged so as to overlap in the up-down direction. By setting it as such an arrangement, it is possible to suppress the risk of not being thermally insulated between the upper switching chamber 60 and the lower switching chamber 70 .

Furthermore, a gap (not shown) is provided between at least one of the left and right ends of the heat insulating partition member 16 and the heat insulating partition member 17 and the inner case 11 . Between the inner box 11 and the outer box 12 is filled with foamed heat insulating material. During the manufacturing process, it is easy to produce a difference in the external dimensions during the foaming process. For example, there will be an inner box 11 to face the In the case of deformation due to the expansion of the indoor side. On the other hand, the thermal insulation partition member 16 and the thermal insulation partition member 17 are not filled with a foamed thermal insulation material, so that it is difficult to produce variation in external dimensions during manufacture. Therefore, considering the assemblability of the thermal insulation partition member 16 and the thermal insulation partition member 17 at a specific location of the inner box 11, it is necessary to provide a foam insulation material for absorbing the foamed thermal insulation material inside the inner box 11. The resulting dimensional tolerances are ideal. At this time, an elastic sealing material (not shown) may also be interposed in at least a part of the gap. By filling the gap with the sealing material, it is possible to prevent the heat bridge. Influence is suppressed.

FIG. 16 is a cross-sectional view showing a modification of the area insulating thermal wall. In addition, about the same structure as the heat insulating partition members 16 and 17 shown in FIG. 15, the same reference numerals are attached, and the overlapping description is abbreviate|omitted. As shown in FIG. 16 , the heat insulating partition members 16 and 17 are provided with expanded polystyrene (expanded styrene) 163a provided at the lower part of the vacuum heat insulating materials V9 and V10, and are provided in a vacuum Expanded polystyrene (expanded styrene) 163b at the upper part of the heat insulating material V9, V10. In this way, it is comprised so that the whole periphery of the vacuum heat insulating material V9, V10 may be covered with the expanded polystyrene 163a, 163b. With this configuration, since the entire system of the vacuum heat insulating materials V9 and V10 is covered, the damage to the vacuum heat insulating materials V9 and V10 can be suppressed more reliably, and it is possible to eliminate the need for use in the aforementioned implementation. The sealing material 164 used in the form. Moreover, about the left and right end parts of the heat insulating partition members 16 and 17, similarly, by setting it as the same arrangement|positioning as FIG. 15, the risk of not being insulated from heat can be suppressed.

Fig. 17 is a cross-sectional view showing the rear insulating partition member. As shown in FIG. 17 , the rear heat insulating partition member 65 includes a vacuum heat insulating material V11 , a housing panel 66 for housing the vacuum heat insulating material V11 , and a holding panel 67 for holding the housing panel 66 . In addition, in this embodiment, the housing|casing is comprised by the accommodating panel 66 and the holding|maintenance panel 67.

The accommodating panel 66 includes a bottom surface 66a in contact with one surface of the vacuum heat insulating material V11, and a side surface 66b erected from the bottom surface 66a. On the outer surface of the side surface 66b, a locking claw 66c is formed to protrude. Moreover, the sealing material 66d is provided in the outer peripheral surface of the vacuum heat insulating material V11. Thereby, the space between the outer peripheral surface of the vacuum heat insulating material V11 and the side surface 66b is filled, and the vacuum heat insulating material V11 can be prevented from moving in the housing panel 66 and damaging the vacuum heat insulating material V11.

The holding panel 67 includes a partition plate 64a for partitioning the upper switching chamber 60 and the cooler storage space 100, an upper holding portion 67b for holding the upper portion of the storage panel 66, and a lower holding portion 67c for holding the lower portion of the storage panel 66. . The upper holding portion 67b is formed in a concave shape so that the concave surface is opened downward. The lower holding portion 67c is formed with a locking hole 67d for engaging the aforementioned locking pawl 66c.

When attaching the accommodation panel 66 in which the vacuum heat insulating material V11 is accommodated, the installation is performed with the exposed surface of the vacuum heat insulating material V11 facing the holding panel 67 side. In this case, the upper part of the accommodating panel 66 is inserted into the upper holding part 67b first, and the upper part is used as a fulcrum to rotate the accommodating panel 66 toward the partition plate 67a. Then, by pressing the receiving panel 66 against the partition plate 67a, the locking claws 66c of the receiving panel 66 are fitted into the locking holes 67d, and the receiving panel 66 is held at the holding panel 67. In this way, by constituting the upper part of the storage panel 66 to be covered by the upper holding part 67b, even if water drips from the upper part of the storage panel 66, the water can be prevented from entering the storage panel 66. . Moreover, when the housing panel 66 is attached to the holding panel 67, since the lower holding part 67c is positioned outside the side surface 66b, it is possible to prevent the vacuum heat insulating material V11 from being damaged.

In addition, when the upper switching chamber 60 is set to the refrigerating temperature zone and the lower switching chamber 70 is set to the freezing temperature zone, since the upper side, the lower side, and the deep side of the upper switching chamber are all the freezing temperature zone, the It becomes difficult to maintain the upper switching chamber 60 in the refrigeration temperature range. Therefore, in the present embodiment, heaters are arranged in the upper switching chamber 60 and the lower switching chamber 70 . Hereinafter, a detailed description will be given with reference to FIGS. 18 to 21 . Fig. 18 is a cross-sectional view showing the arrangement of the heaters in the upper switching chamber and the lower switching chamber. Fig. 19 is a plan view showing the arrangement of the heater on the back side. Fig. 20 is a cross-sectional view showing the arrangement of the heater provided at the blower fan and the fan casing. Fig. 21 is a cross-sectional view showing a modified example of the arrangement of the heater provided in the blower fan.

As shown in FIG. 18, the refrigerator main body 10 is equipped with heaters H1, H2, H3, H4, and H5. These heaters H1 to H5 are constituted by surface heaters, and are used to raise the temperature or prevent dew condensation. In addition, the arrangement and the number of heaters shown in this embodiment are only one example, and can be appropriately set according to the heat balance of the upper switching chamber 60 and the lower switching chamber 70 .

The heater H1 is provided under the heat insulating partition member 16 which constitutes the upper surface of the upper switching chamber 60 . The heater H2 is provided on the upper surface of the insulating partition member 17 which constitutes the lower surface of the upper-stage switching chamber 60 . The heater H3 is provided on the front surface of the rear heat insulating partition member 65 constituting the rear surface of the upper-stage switching chamber 60 . The heater H4 is provided under the heat insulating partition member 17 which constitutes the upper surface of the lower-stage switching chamber 70 . The heater H5 is provided on the urethane side surface of the inner case 11 which constitutes the bottom surface of the lower-stage switching chamber 70 .

For example, when the upper switching chamber 60 is set to the refrigerating temperature zone and the lower switching chamber 70 is set to the freezing temperature zone, it is presumed that the upper switching chamber 60 comes from the front side (door side) and the left and right side sides. The inflow of heat can be estimated as the outflow of heat from the upper, lower, and rear surfaces of the upper switching chamber 60 . Therefore, the heaters H1 , H2 , and H3 are energized so that the upper switching chamber 60 becomes the heat balance of the refrigeration temperature zone, and the upper switching chamber 60 is heated.

In addition, when the upper switching chamber 60 is set to the freezing temperature zone and the lower switching chamber 70 is set to the refrigerating temperature zone, it is presumed that the front side (door side), the left and right side surfaces, and the bottom surface of the upper switching chamber 60 are The inflow of heat from the side can be estimated as the outflow of heat from the upper surface side and the rear surface side of the lower-stage switching chamber 70 . Therefore, the heaters H4 and H5 are energized to heat the lower switching chamber 70 so that the lower switching chamber 70 becomes the heat balance of the refrigeration temperature zone.

As shown by bold lines in FIG. 19 , heaters H6 , H7 , H8 , H9 , H10 , and H11 are provided at the rear heat insulating partition member 65 . These heaters H6 to H11 are constituted by surface heaters.

The heater H6 is installed so as to surround the entire periphery of the damper member 120 . The heater H7 is installed so as to surround the entire periphery of the damper member 130 . The heater H8 is installed so as to surround the entire periphery of the damper member 140 . The heaters H6 to H8 are used to prevent frost from adhering to the damper members 120 to 140 and prevent the shutters 121 , 131 , 141 a and 142 a (refer to FIGS. 6 to 8 ) from being opened. For example, it is attached so as to surround the valve boxes 122a, 132a, 141c, and 142c (refer to FIGS. 6 to 8 ) for one turn.

The heater H9 is provided on the wall surface of the fan casing 111 . With this, it is possible to prevent frost or water from accumulating in the fan casing 111 . The heater H10 is provided in the vicinity of the blower fan 90 . Thereby, it is possible to prevent frost from adhering to the blower fan 90 .

The heater H11 is provided at the wall surface of the return flow path 41b and the return port 41a. Thereby, it is possible to prevent frost from adhering to the return flow path 41b.

As shown in FIG. 20 , the heater H9 is disposed at the inner wall surface 111t of the fan casing 111 and is formed along the wall surface facing the outer periphery of the blower fan 90 .

The blower fan 90 is fixed to the partition plate 67 a of the rear heat insulating partition member 65 via the bracket 92 . The bracket 92 includes a leg portion 92a extending in a direction away from the rear face of the partition plate 67a, a support portion 92b extending parallel to the partition plate 67a, and the support portion 92b and the support portion 92b. The blower fan 90 is constituted as a connecting portion 92c for connecting.

The heater H10 for the blower fan 90 is provided on the side of the blower fan 90 (outdoor side, the fan case 111 side) of the partition plate 67a. In addition, the heater H10 is configured in a disk shape or a ring shape when viewed in a plane from the axial direction.

In addition, as shown in FIG. 21 , the heater H10 may be provided on the indoor side (upper switching chamber 60 side) of the partition plate 67a of the rear heat insulating partition member 65 . For example, the partition plate 67a is formed at a position facing the blower fan 90, and a recessed portion 67e is formed on the side of the blower fan 90, and the heater H10 is provided in the recess portion 67e. By providing the recessed portion 67e and arranging the heater H10 in this way, there is no obstacle when the housing panel 66 (refer to FIG. 17 ) on the front side where the fishing zone partition 67a is provided is provided.

FIG. 22 is a diagram showing an operation panel for switching temperature zones. In addition, the structure shown below is only an example, and is not limited to this embodiment. As shown in FIG. 22, a control panel (operation panel) 150, for example, is provided at the surface of the refrigerator compartment door 2, and is electrically connected to the control board 13 (refer to FIG. 2). In addition, the control panel 150 is provided with a switching operation key 150a for switching the upper switching chamber 60 (switching chamber (upper)) to one of the refrigerating temperature zone and the freezing temperature zone, and the display of the refrigerating temperature zone or the freezing temperature zone. The temperature zone display part 150b, and the intensity display part 150c which displays the intensity|strength of the set temperature zone. In addition, the control panel 150 is also configured in the same manner as described above for the switching of the lower-stage switching chamber 70 (switching chamber (lower)).

As an operation method, for example, by long pressing the switch operation key 150a (for example, for 5 seconds), the refrigeration temperature zone and the freezing temperature zone can be switched, and the switched temperature zone is displayed. For example, when it is set as a refrigeration temperature zone, the character "refrigeration" is displayed on the temperature zone display part 150b, and the character is lit in green. In addition, by short pressing the switching operation key 150a after switching the temperature zone, "weak", "medium", and "strong" of the intensity display section 150c are displayed in sequence for each short pressing. Turn on the lights to adjust the temperature. For example, when set to "weak", the system is set to 5°C, by setting to "medium", the system is set to 3°C, and by setting to "strong", the system is set to 1°C. In addition, when it is set to the freezing temperature zone, the character "Frozen" is displayed on the temperature zone display part 150b, and the character is lit in blue. In this way, by long pressing the key to switch the temperature zone, it is possible to suppress the situation that the temperature zone is switched by mistake.

In addition, although not shown, the upper switching chamber door 6 and the lower switching chamber door 7 may be provided with a green light-emitting portion and a blue light-emitting portion, respectively. When the upper switching chamber 60 is set to the refrigerating temperature zone, the green light-emitting portion is turned on, and the surface of the upper switching chamber door 6 is made to emit green light. In addition, when it is set to the freezing temperature range, the blue light-emitting part is lit, and the surface of the upper switching chamber door 6 is made to emit blue light.
