Therefore, even if drain water flows down on the case of the drive unit 143 when frost generated on the damper member 140 melts, the terminal portion 143b can be prevented from being exposed to the drain water.

FIG. 11 is a cross-sectional view showing the arrangement of damper members.
When the damper member 120 is arranged as shown in FIG. 11A, the water W tends to accumulate on the inner wall surface of the lower portion of the valve box 122a of the flapper support portion 122. As shown in FIG. If the water W freezes at such a position, there is a risk that the flapper 121 will be caught in the ice and will not open. Therefore, as shown in FIG. 11B, by inclining the damper member 120 so that the valve body 122a descends toward the rear side, it is possible to prevent the water W from accumulating on the back side of the flapper support portion 122. The damper members 130 and 140 are similarly inclined.

Also, when the damper member 120 is arranged as shown in FIG. However, since the damper member 120 is provided with a heater H6 (see FIG. 19), which will be described later, the opening of the flapper 121 causes the water to flow rearward.

Also, the resin material of the damper member 120 may be composed of a water-repellent resin or a hydrophilic resin.

FIG. 12 is a schematic diagram illustrating the flow of cool air in the refrigerator according to this embodiment.
As shown in FIG. 12, in the refrigerating chamber 30 of the refrigerator 1, cold air generated by a cooler 80B provided exclusively for the refrigerating chamber 30 is sucked into a blower fan 91, and a plurality of air blowers provided on the back surface of the refrigerating chamber 30 is discharged from the discharge port (not shown). After cooling the food, the cold air returns to cooler 80B from a return port (not shown) provided at the bottom of refrigerator compartment 30 .

In the ice making compartment 40 and the freezing compartment 50 of the refrigerator 1, the cool air generated by the cooler 80A is blown by the blower fan 90 to the outlet 40a (see FIG. 3) provided in the ice making compartment 40 and the outlet provided in the freezing compartment 50. It is discharged from 50a (see FIG. 3). After cooling the food, the air is sucked into the return port 41a provided on the back side of the freezer compartment 50, passes through the return flow path 41b, and returns to the cooler 80A. In this manner, the cold air generated by the cooler 80A is constantly sent to the ice making compartment 40 and the freezing compartment 50. As shown in FIG.

When the upper switching chamber 60 is set to the freezing temperature range, the damper member 120 is opened. In this case, cold air generated by cooler 80A passes through damper member 120 . Cold air is directly supplied to the food in the upper storage container 61 from the outlet 63a provided in the upper switching chamber 60, and is directly supplied to the food in the lower storage container 62 from the outlet 63b.

Further, when the upper switching chamber 60 is set to the refrigerating temperature range, the damper portion 141 of the damper member 140 is opened. In this case, cool air generated by cooler 80A passes through damper section 141 . Cold air flows 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 indirectly cooling the food. As a result, 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 range, cold air generated by the cooler 80A passes through the damper member 130 . The food in the upper storage container 71 is directly supplied from the discharge port 73a provided in the lower switching chamber 70, and the food in the lower storage container 72 is directly supplied from the discharge port 73b.

Further, when the lower switching chamber 70 is set to the refrigerating temperature range, the damper portion 142 of the damper member 140 is opened. In this case, cool air generated by cooler 80A passes through damper portion 142 and flow path 116 (see FIG. 4). Cold air flows 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 indirectly cooling the food. As a result, drying of the food in the upper storage container 71 and the lower storage container 72 can be suppressed.

Thus, in the refrigerator 1 of the first embodiment, the upper switchable compartment 60 can be set to the refrigerating temperature range and the lower switchable compartment 70 can be set to the freezing temperature range. In the refrigerator 1, the upper switchable compartment 60 can be set to the freezing temperature range, and the lower switchable compartment 70 can be set to the refrigerating temperature range. In the refrigerator 1, both the upper switchable chamber 60 and the lower switchable chamber 70 can be set to the freezing temperature range. In the refrigerator 1, both the upper switchable chamber 60 and the lower switchable chamber 70 can be set to the refrigerating temperature range.

Fig. 13(a) is a cross-sectional view showing a refrigerator equipped with a centrifugal fan as the blower fan of the first embodiment, and Fig. 13(b) is a cross-sectional view showing a refrigerator equipped with a propeller fan as the blower fan of the comparative example. .
As shown in FIG. 13( a ), the refrigerator 1 includes a centrifugal fan (turbo fan or sirocco fan) as the blower fan 90 , and the blower fan 90 is arranged behind the rear heat-insulating partition member 65 . Such a blower fan 90 sucks cool air from the center side in the radial direction and discharges cool air in the circumferential direction. Just make sure you have the space. Therefore, in the first embodiment, the dimension D1 in the front-rear direction of the cooler storage space 100 provided on the back side of the upper switching chamber 60 can be reduced.

On the other hand, a refrigerator 200 shown as a comparative example in FIG. In such a case, the blower fan 201 is arranged at an angle, and a suction space and a discharge space are required at the rear and front, respectively. Therefore, it is necessary to secure a large dimension D100 (>D1) in the front-rear direction of the space of the cooling flow path provided on the back side of the upper switching chamber 203 .

Thus, in the first embodiment, the volume Q1 of the upper switchable chamber 60 when using the blower fan 90 can be ensured to be larger than the volume Q100 of the upper switchable chamber 203 when using the blower fan 201 as a comparative example. This makes it possible to increase the storage amount of food in the upper switchable chamber 60 .

Also, by separating the cooler 80B for the refrigerator compartment 30 and the cooler 80A below the refrigerator compartment 30, the cooler 80A can be made smaller (for example, from 7 stages to 5 stages). Thereby, the vertical dimension of the cooler storage space 100 can be made compact. Therefore, the volume of the forward projection on the back surface in the ice making compartment 40 and the freezing compartment 50 can be reduced, and the volume in the ice making compartment 40 and the freezing compartment 50 can be increased.

A blower fan 90 is provided on the upper projection of the cooler 80A, and at least a part of the damper member 120 (see FIG. 6) is present on the upper projection of the blower fan 90. As shown in FIG. Furthermore, the axial direction of the blower fan 90 and the longitudinal direction of the opening 122b of the damper member 120 are provided substantially parallel. Therefore, the cool air blown in the centrifugal direction from the blower fan 90 comes into contact with the open flapper 121 of the damper member 120, and is blown into the upper switching chamber 60 located on the near side of the opening 122b. In addition, the supporting portion 92b of the blower fan 90 or the surface of the holding panel 67 facing the supporting portion 92b (see FIG. 20), the front portion provided with the opening 122b of the damper member 120, the vacuum heat insulating material V11 or the vacuum heat insulating material The rear portion of V11 and the opposing holding panel 67 are arranged substantially parallel to each other. As a result, it is possible to reduce the longitudinal dimensions of the cooler storage space 100 and the airflow path that guides the airflow from the blower fan 90, and to secure a large capacity for the upper switching chamber 60. FIG.

FIG. 14 is an exploded perspective view showing a heat insulating partition member.
As shown in FIG. 14, the heat insulating partition member 16 includes a synthetic resin case 160 consisting of a lower case 161 and an upper case 162, expanded polystyrene (so-called expanded polystyrene) 163 as a heat insulating material, and vacuum as another heat insulating material. and a heat insulating material V9. Since the heat insulating partition member 17 has the same configuration as 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 portion 161a with an upright outer peripheral edge portion. The side surface portion 161a is formed on the entire four sides. Further, the lower case 161 has locking claws 161b, 161b formed on opposite sides of the outer surface of the side portion 161a.

The upper case 162 is formed in a rectangular shape and has a side surface portion 162 a whose outer peripheral edge portion extends toward the lower case 161 . The side surface portion 162a is formed along the entire four sides. Further, the upper case 162 is formed with engaging holes 162b in which the engaging claws 161b are engaged in opposite sides of the outer surface of the side surface portion 162a.

The expanded polystyrene 163 has a rectangular shape that fits 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 portion 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 to be accommodated in the lower case 161. As shown in FIG. Further, the vacuum heat insulating material V9 is set to have a thickness such that the surface of the vacuum heat insulating material V9 is positioned at the upper end of the side surface portion 161a when the vacuum heat insulating material V9 is housed in the lower case 161 together with the foamed polystyrene 163.

A sealing material 164 is attached to the side surface of the vacuum heat insulating material V9. This sealing material 164 is formed on the entire outer peripheral surface of the vacuum heat insulating material V9. By providing this 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 within the lower case 161 and being damaged.

In such a heat insulating partition member 16, after the polystyrene foam 163 and the vacuum heat insulating material V9 are accommodated in the lower case 161, the upper case 162 is put thereon. In this case, the side surface portion 162a of the upper case 162 is positioned outside the side surface portion 161a of the lower case 161 . Therefore, when the upper case 162 is put on the lower case 161, the side portion 162a does not come into contact with the vacuum heat insulating material V9, thereby preventing the vacuum heat insulating material V9 from being damaged.

Also, the inner surface of the upper case 162 is provided with a double-sided tape 162c. By bonding 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 separated from the lower case 161. FIG. Moreover, the formation of a gap (space) between the upper case 162 and the vacuum heat insulating material V9 can be suppressed by the double-faced tape 162c, and the formation of frost and dew in the gap can be suppressed.

In this 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 is described as an example. However, the configuration is not limited to this, and the lower case 161 and the upper case 162 may be fixed with screws.

FIG. 15 is a cross-sectional view showing an attached state of the heat insulating partition member.
As shown in FIG. 15 , when the heat insulating partition member 16 is attached, a partition wall 18 is provided above the heat insulating partition member 16 to partition the ice making compartment 40 and the freezer compartment 50 left and right. Therefore, the heat insulating partition member 16 cannot be attached from the upper side, and must be attached from the lower side of the partition wall 18.例文帳に追加

Ribs 11e integral with the inner box 11 are formed on the left and right side surfaces of the inner box 11, and the inner side (back side) is filled with hard urethane foam to ensure heat insulation. The top surface of the end portion of the heat insulating partition member 16 is pressed from below the rib 11e to position it, and the fixed member 11f formed of a separate member is pressed against the bottom surface of the end portion of the heat insulating partition member 16 from below. Then, the fixing member 11f is fixed to the inner box 11 while the heat insulating partition member 16 is sandwiched between the rib 11e and the fixing member 11f.

By the way, the vacuum heat insulating material V9 is likely to have variations in outer dimensions during manufacturing, and a difference widens between the maximum vacuum heat insulating material and the minimum vacuum heat insulating material. Depending on the magnitude of such a difference, heat insulation may not be possible, and in that case frost may occur at the end of the switchable compartment (in the case of a refrigerating temperature zone compartment). Therefore, the tip portion P2 of the urethane (hard urethane foam) of the rib 11e is positioned inside (inward) in the left-right direction (width direction) from the position (peripheral end portion P1) where the vacuum heat insulating material V9 has the minimum dimension. ing. In other words, the ends of the vacuum heat insulating material V9 and the ribs 11e filled with urethane are arranged so as to overlap in the vertical direction. By such arrangement, the risk of not being insulated 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 can be suppressed.

When the heat insulating partition member 17 that separates the upper switchable chamber 60 and the lower switchable chamber 70 is attached, only the upper switchable chamber 60 is above the heat insulating partition member 17 . Therefore, unlike the heat insulating partition member 16, the heat insulating partition member 17 can be attached from above. The heat insulating partition member 17 is fixed to ribs 11 g formed on the left and right side surfaces of the inner box 11 .

Similarly, for the heat insulating partition member 17, the tip portion P2 of urethane (hard urethane foam) of the rib 11g is positioned laterally ( width direction). In other words, the ends of the vacuum heat insulating material V10 and the ribs 11g filled with urethane are arranged so as to overlap in the vertical direction. With such an arrangement, it is possible to reduce the risk that insulation is not provided between the upper switchable chamber 60 and the lower switchable chamber 70 .

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 . The space between the inner box 11 and the outer box 12 is filled with a foamed heat insulating material, and the outer dimensions are likely to vary during the foaming process during manufacturing. Sometimes. On the other hand, the heat-insulating partition member 16 and the heat-insulating partition member 17 are not filled with foamed heat-insulating material, so that the outer dimensions are less likely to vary during manufacturing. Therefore, considering ease of assembly of the insulating partition member 16 and the insulating partition member 17 at predetermined locations in the inner box 11, it is possible to provide a gap for absorbing the dimensional tolerance that occurs after foaming of the foamed insulating material inside the inner box 11. desirable. At this time, an elastic sealing material (not shown) may be interposed in at least part of the gap, and the effect of heat bridge can be suppressed by filling the gap with the sealing material.

FIG. 16 is a cross-sectional view showing a modification of the partitioning hot wall. The same reference numerals are assigned to the same components as those of the heat-insulating partition members 16 and 17 shown in FIG. 15, and overlapping descriptions are omitted.
As shown in FIG. 16, the insulating partition members 16 and 17 are composed of expanded polystyrene (expanded polystyrene) 163a provided below the vacuum heat insulating materials V9 and V10, and expanded polystyrene (expanded polystyrene) provided above the vacuum heat insulating materials V9 and V10. 163b and . In this manner, the vacuum heat insulating materials V9 and V10 are entirely covered with expanded polystyrene 163a and 163b. With such a configuration, the vacuum heat insulating materials V9 and V10 are entirely covered, so damage to the vacuum heat insulating materials V9 and V10 can be suppressed more reliably, and the sealing material 164 used in the above-described embodiment can be eliminated. can. Also, by arranging the left and right ends of the heat insulating partition members 16 and 17 in the same manner as in FIG. 15, the risk of not being insulated can be suppressed.

FIG. 17 is a cross-sectional view showing a rear heat insulating partition member.
As shown in FIG. 17, the rear heat insulating partition member 65 is configured by having a vacuum heat insulating material V11, a housing panel 66 housing the vacuum heat insulating material V11, and a holding panel 67 holding the housing panel 66. ing. In addition, in this embodiment, the housing panel 66 and the holding panel 67 constitute a case.

The housing panel 66 has a bottom surface 66a with which one surface of the vacuum heat insulating material V11 is in contact, and side surfaces 66b rising from the bottom surface 66a. A locking claw 66c is formed to protrude from the outer surface of the side surface 66b. A sealing material 66d is provided on the outer peripheral surface of the vacuum heat insulating material V11. Thereby, the gap 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 within the housing panel 66 and damaging the vacuum heat insulating material V11.

The holding panel 67 includes a partition plate 67a that separates the upper switching chamber 60 and the cooler storage space 100, an upper holding portion 67b that holds the upper portion of the accommodation panel 66, and a lower holding portion 67c that holds the lower portion of the accommodation panel 66. and have The upper holding portion 67b is formed in a concave shape so that the concave surface opens downward. The lower holding portion 67c is formed with a locking hole 67d in which the locking claw 66c is locked.

When the housing panel 66 containing the vacuum heat insulating material V11 is mounted, it is mounted with the exposed surface of the vacuum heat insulating material V11 directed toward the holding panel 67 side. In this case, the upper portion of the housing panel 66 is first inserted into the upper holding portion 67b, and the housing panel 66 is rotated toward the partition plate 67a using the upper portion as a fulcrum. By pressing the housing panel 66 against the partition plate 67 a , the locking claws 66 c of the housing panel 66 are fitted into the locking holes 67 d , and the housing panel 66 is held by the holding panel 67 . By covering the upper part of the housing panel 66 with the upper holding part 67b in this way, even if water drips from the upper part of the housing panel 66, it is possible to prevent water from entering the housing panel 66.例文帳に追加Further, when the housing panel 66 is attached to the holding panel 67, the lower holding portion 67c is positioned outside the side surface 66b, so that the vacuum heat insulating material V11 can be prevented from being damaged.

By the way, if the upper switchable chamber 60 is set to the refrigerating temperature range and the lower switchable chamber 70 is set to the freezing temperature range, the upper, lower and back sides of the upper switchable chamber 60 are all set to the freezing temperature range. in the refrigeration temperature range becomes difficult. Therefore, in the present embodiment, heaters are arranged in the upper switching chamber 60 and the lower switching chamber 70 . A detailed description will be given below with reference to FIGS. 18 to 21. FIG. FIG. 18 is a cross-sectional view showing the arrangement of heaters in the upper switchable chamber and the lower switchable chamber. FIG. 19 is a plan view showing the arrangement of heaters on the back side. FIG. 20 is a cross-sectional view showing the arrangement of heaters provided in the blower fan and the fan casing. FIG. 21 is a cross-sectional view showing a modification of the arrangement of heaters provided in the blower fan.

As shown in FIG. 18, refrigerator body 10 includes heaters H1, H2, H3, H4, and H5. These heaters H1 to H5 are plane heaters and are used to increase the temperature or prevent condensation. Note that the arrangement and number of heaters shown in the present embodiment are examples, and are appropriately set according to the heat balance of the upper switchable chamber 60 and the lower switchable chamber 70 .

The heater H<b>1 is provided on the lower surface of the heat insulating partition member 16 forming the upper surface of the upper switching chamber 60 . The heater H<b>2 is provided on the upper surface of the heat insulating partition member 17 forming the lower surface of the upper switching chamber 60 . The heater H<b>3 is provided on the front surface of the rear heat insulating partition member 65 that forms the rear surface of the upper switching chamber 60 . The heater H4 is provided on the lower surface of the heat insulating partition member 17 forming the upper surface of the lower switching chamber 70 . The heater H5 is provided on the urethane side surface of the inner box 11 forming the bottom surface of the lower switching chamber 70 .

For example, when the upper switchable chamber 60 is set to the refrigerating temperature range and the lower switchable chamber 70 is set to the freezing temperature range, heat is expected to flow in from the front side (door side) and left and right side surfaces of the upper switchable chamber 60. It is assumed that heat flows out from the upper, lower and rear surfaces of the upper switching chamber 60 . Therefore, the heaters H1, H2 and H3 are energized to heat the upper switchable chamber 60 so that the upper switchable chamber 60 has a heat balance within the refrigerating temperature range.

When the upper switchable chamber 60 is set to the freezing temperature range and the lower switchable chamber 70 is set to the refrigerating temperature range, heat flows in from the front side (door side), the left and right side surfaces, and the bottom side of the upper switchable chamber 60 . It is assumed that heat flows out from the upper surface side and the rear surface side of the lower switching chamber 70 . Therefore, the heaters H4 and H5 are energized to heat the lower switchable chamber 70 so that the lower switchable chamber 70 has a heat balance in the refrigerating temperature range.

As indicated by thick lines in FIG. 19, the back heat insulating partition member 65 is provided with heaters H6, H7, H8, H9, H10, and H11. These heaters H6 to H11 are composed of planar heaters.

The heater H6 is provided so as to surround the entire circumference of the damper member 120 . The heater H7 is provided so as to surround the entire circumference of the damper member 130 . The heater H8 is provided so as to surround the entire circumference of the damper member 140 . The heaters H6 to H8 are for preventing the flappers 121, 131, 141a, 142a (see FIGS. 6 to 8) from not opening due to frost adhering to the damper members 120 to 140. FIG. For example, it is attached to the valve bodies 122a, 132a, 141c, 142c (see FIGS. 6 to 8) so as to make one turn.

The heater H9 is provided on the wall surface of the fan casing 111 . As a result, it is possible to prevent frost and water from accumulating in the fan casing 111 . The heater H10 is provided near the blower fan 90 . Thereby, it is possible to prevent frost from adhering to the blower fan 90 .

The heater H11 is provided on the wall surface of the return channel 41b and the return port 41a. As a result, it is possible to prevent frost from adhering to the inside of the return channel 41b.

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

The blower fan 90 is fixed to the partition plate 67 a of the rear heat insulating partition member 65 via a bracket 92 . The bracket 92 has a leg portion 92a extending away from the rear surface of the partition plate 67a, a support portion 92b extending parallel to the partition plate 67a, and a connecting portion 92c connecting the support portion 92b and the blower fan 90. is configured as

The heater H10 for the blower fan 90 is provided on the partition plate 67a on the blower fan 90 side (on the outside of the refrigerator, on the side of the fan casing 111). In addition, the heater H10 is configured in a disk shape or an annular shape in a plan view from the axial direction.

As shown in FIG. 21, the heater H10 may be provided inside the partition plate 67a of the rear heat insulating partition member 65 (on the side of the upper switching chamber 60). For example, the partition plate 67a is formed with a recessed portion 67e recessed toward the blower fan 90 at a position facing the blower fan 90, and the heater H10 is provided in this recessed portion 67e. By providing the recessed portion 67e and arranging the heater H10 in this way, it does not interfere with the installation of the accommodation panel 66 (see FIG. 17) provided on the front side of the partition plate 67a.

FIG. 22 is a diagram showing an operation panel for switching temperature zones. Note that the configuration shown below is an example and is not limited to this embodiment.
As shown in FIG. 22, a control panel (operating panel) 150 is provided, for example, on the surface of the refrigerator compartment door 2 and electrically connected to the control board 13 (see FIG. 2). The control panel 150 also includes a switching operation button 150a for switching the upper switching chamber 60 (switching chamber (upper)) between the refrigerating temperature range and the freezing temperature range, and a temperature range indicator for displaying the refrigerating temperature range or the freezing temperature range. It has a display section 150b and an intensity display section 150c that displays the intensity of the set temperature range. The control panel 150 is also configured in the same manner as described above for switching the lower switching chamber 70 (switching chamber (lower)).

As an operation method, for example, by pressing and holding the switching operation button 150a for a long time (for example, 5 seconds), the refrigeration temperature zone and the freezing temperature zone can be switched, and the switched temperature zone is displayed. For example, when the refrigerating temperature range is set, temperature range display section 150b displays the characters "refrigerate" and the characters are lit in green. Further, by pressing the switching operation button 150a for a short time after switching the temperature zone, the strength display section 150c "weak", "medium", and "strong" light up in order for each short press, and the temperature can be adjusted. can. For example, setting to "weak" sets the temperature to 5°C, setting to "medium" sets the temperature to 3°C, and setting to "strong" sets the temperature to 1°C. Further, when the freezing temperature range is set, the temperature range display portion 150b displays the characters "Frozen" and the characters light up in blue. In this way, by pressing the button for a long time to switch the temperature zone, it is possible to prevent the temperature zone from being erroneously switched.

Although not shown, the upper switchable chamber door 6 and the lower switchable chamber door 7 may be provided with a green light emitting portion and a blue light emitting portion, respectively. When the upper switchable chamber 60 is set to the refrigerating temperature range, the green light-emitting part is turned on to cause the surface of the upper switchable chamber door 6 to emit green light. Further, when the freezing temperature range is set, the blue light-emitting portion is turned on, and the display on the upper switching chamber door 6 is made to emit blue light. Also, the lower switching chamber door 7 can be configured in the same manner. With such a configuration, the current temperature zone can be confirmed without the user opening the upper switchable chamber door 6 or the lower switchable chamber door 7 .

In addition, since switching of the temperature zone of the switching chamber and switching of the strength can be performed by long pressing and short pressing of the same switching operation button 150a, the substrate structure of the control panel can be simplified and reduced in cost ( For example, the number of switch elements such as capacitance can be reduced), and the simplification of the control panel suppresses complication of the operation method and improves operability.

Further, the switching operation button 150a, the temperature range display section 150b, and the intensity display section 150c are lit in a warm color or a neutral color when the refrigeration temperature range is set, and when the freezing temperature range is set, The user's visibility can be improved by lighting in a cool color.

In addition, in the case of the operation to change the temperature zone, the temperature zone is not switched just by performing the switching operation. may As a result, it is possible to more reliably prevent the temperature zone from being set erroneously.

FIG. 23 is a diagram showing a modification of the layout of the control panel.
As shown in FIG. 23 , the refrigerator 1 has a control panel 150 inside the refrigerator compartment 30 . This control panel 150 is, for example, similar to that shown in FIG. 22, and is electrically connected to the control board 13 (see FIG. 2). The position of the control panel 150 is not limited to the left side of the inner box 11, but may be the right side of the inner box 11 or the inner wall surfaces of the refrigerating compartment doors 2 and 3, and can be changed as appropriate.

Thus, by providing the control panel 150 inside the refrigerator such as the refrigerator compartment 30, it is possible to suppress erroneous switching of the temperature zone more than when the control panel 150 is provided outside the refrigerator.

FIG. 24 is a diagram showing another means of confirming the temperature zone.
