That is, the damper member 140 is configured such that both of the damper portions 141 and 142 can be closed and both of the damper portions 141 and 142 can be opened. The damper member 140 is configured to open the damper portion 141 and close the damper portion 142, and to close the damper portion 141 and open the damper portion 142. As described above, by combining the damper portion 141 and the damper portion 142 into the damper member 140, the manufacturing cost can be reduced. In the present embodiment, the case where the damper units 141 and 142 are integrated is described as an example, but the damper units 141 and 142 may be configured separately.

  As shown in FIG. 10, the back sides of the damper portions 141 and 142 of the damper member 140 have a shape in which the periphery of the flappers 141a and 142a is open toward the back side. That is, the flapper support portions 141b and 142b have the valve boxes 141c and 142c that are open rearward. A groove-shaped gap is formed between the valve boxes 141c and 142c and the valve seats 141e and 142e (see FIG. 9). In other words, gaps S1 and S2 are formed around the flappers 141a and 142a.

  Note that, similarly to the damper member 140, the damper members 120 and 130 also have a shape that is open toward the back side and has a gap formed around the flappers 121 and 131.

  The flapper 141a has a rotating shaft 141g, and is rotatably supported inside the valve box 141c. The flapper 142a has a rotating shaft 142g, and is rotatably supported inside the valve box 142c. The rotating shaft 141g and the rotating shaft 142g are arranged so that their axial directions are parallel to each other, and are formed at positions where they do not overlap each other in the axial direction. Further, the flappers 141a and 142a are configured to open in mutually opposite directions in a direction orthogonal to the axial direction.

  A female connector 143a for control is provided on the back side of the case of the drive unit 143. The female connector portion 143a has a terminal portion 143b extending toward the damper portion 142, and is electrically connected by inserting a male connector (not shown) into the female connector portion 143a from below in the vertical direction. Done. Further, the damper member 140 is arranged such that the damper portion 141 is located vertically above the fan casing 111 (see FIG. 4) and the damper portion 142 is located below the fan casing 111, and the female connector portion 143a is arranged downward. Therefore, even if the drain water generated when the frost generated in the damper member 140 melts flows down on the case of the drive unit 143, the terminal unit 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 arrangement shown in FIG. 11A, the water W easily accumulates on the inner wall surface of the lower part of the valve box 122a of the flapper support portion 122 in the arrangement shown in FIG. If the water W freezes in such a position, the flapper 121 may be caught by the ice and may not be opened. Therefore, as shown in FIG. 11B, the water W can be prevented from accumulating on the back side of the flapper supporting portion 122 by inclining the damper member 120 so that the valve box 122a is lowered toward the rear side. Note that the damper members 130 and 140 are similarly arranged to be inclined.

  When the damper member 120 is arranged as shown in FIG. 11B, water will accumulate in the recess formed by the valve seat 122c and the flapper 121. However, since the damper member 120 is provided with a heater H6 described later (see FIG. 19), the water flows to the rear side by opening the flapper 121.

  Further, the resin material of the damper member 120 may be made of a resin having water repellency or a resin having hydrophilicity.

FIG. 12 is a schematic diagram illustrating the flow of cool air in the refrigerator according to the present embodiment.
As shown in FIG. 12, in the refrigerator compartment 30 of the refrigerator 1, the cool air generated by the cooler 80 </ b> B provided exclusively for the refrigerator compartment 30 is sucked into the blower fan 90, and a plurality of cool air is provided on the back surface in the refrigerator compartment 30. Is discharged from a discharge port (not shown). The cool air after cooling the food returns to the cooler 80B from a return port (not shown) provided at the lower part of the refrigerator compartment 30.

  In the ice making room 40 and the freezing room 50 of the refrigerator 1, the cool air generated by the cooler 80 </ b> A is discharged by the blower fan 90 into the discharge opening 40 a (see FIG. 3) provided in the ice making room 40 and the discharge opening provided in the freezing room 50. It is discharged from 50a (see FIG. 3). Then, the air after cooling the food is sucked into the return port 41a provided on the back side of the freezing room 50, and returns to the cooler 80A through the return flow path 41b. Thus, in the ice making room 40 and the freezing room 50, the cool air generated by the cooler 80A is always sent.

  When the upper switching chamber 60 is set in 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. Then, the cool 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 is also directly supplied to the food in the lower storage container 62 from the discharge port 63b.

  When the upper switching chamber 60 is set in the refrigeration temperature zone, the damper portion 141 of the damper member 140 is opened. In this case, the cool air generated by the cooler 80A passes through the damper unit 141. Then, the cold air flows from the discharge port 63c provided in the upper switching chamber 60 to the outside of the upper storage container 61 and the outside of the lower storage container 62, whereby the food is indirectly cooled. 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 in the freezing temperature zone, the cool air generated by the cooler 80A passes through the damper member 130. And it 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 is also directly supplied to the food in the lower storage container 72 from the discharge port 73b.

  When the lower switching chamber 70 is set in the refrigeration temperature zone, the damper portion 142 of the damper member 140 is opened. In this case, the cool air generated by the cooler 80A passes through the damper section 142 and the flow path 116 (see FIG. 4). Then, the cold air flows from the discharge port 73c provided in the lower switching chamber 70 to the outside of the upper storage container 71 and the outside of the lower storage container 72, whereby the food is indirectly cooled. Thereby, the 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 switching chamber 60 can be set in the refrigeration temperature zone and the lower switching chamber 70 can be set in the freezing temperature zone. Further, in the refrigerator 1, the upper switching chamber 60 can be set in the freezing temperature zone and the lower switching chamber 70 can be set in the refrigeration temperature zone. In the refrigerator 1, both the upper switching chamber 60 and the lower switching chamber 70 can be set in the freezing temperature zone. In the refrigerator 1, both the upper switching chamber 60 and the lower switching chamber 70 can be set in the refrigeration temperature zone.

FIG. 13A is a cross-sectional view illustrating a refrigerator including a centrifugal fan as a blower fan according to the first embodiment, and FIG. 13B is a cross-sectional view illustrating a refrigerator including a propeller fan as a blower fan according to a comparative example. .
As shown in FIG. 13A, the refrigerator 1 includes a centrifugal fan (turbo fan or sirocco fan) as the blower fan 90, and the blower fan 90 is disposed behind the rear heat insulating partition member 65. Such a blower fan 90 sucks cool air from the center in the radial direction, and discharges cool air in the circumferential direction. Therefore, the space in the axial front of the blower fan 90 can be narrowed, and the space in the rear (suction side) in the axial direction can be reduced. You only need to secure space. Therefore, in the first embodiment, the dimension D1 in the front-rear direction of the cooler storage space 100 provided on the rear side of the upper switching chamber 60 can be reduced.

  On the other hand, the refrigerator 200 shown as a comparative example in FIG. 13B includes a propeller fan as the blower fan 201, and the blower fan 201 is arranged behind the rear heat insulating partition member 202. In such a case, the blower fan 201 is disposed obliquely, and a suction space and a discharge space are required at the rear and the front, respectively. Therefore, it is necessary to ensure a large dimension D100 (> D1) in the front-rear direction of the space of the cooling channel provided on the back side of the upper switching chamber 203.

  As described above, in the first embodiment, the volume Q1 of the upper switching chamber 60 when the blowing fan 90 is used can be larger than the volume Q100 of the upper switching chamber 203 when the blowing fan 201 is used as a comparative example. This makes it possible to increase the amount of food stored in the upper switching chamber 60.

  Further, by separating the cooler 80B for the refrigerator compartment 30 from the cooler 80A below the refrigerator compartment 30, the cooler 80A can be reduced in size (for example, from seven stages to five stages). Thus, the vertical dimension of the cooler storage space 100 can be made compact. For this reason, it is possible to reduce the volume of the forward protrusion on the back surface inside the ice making room 40 and the inside of the freezing room 50, and it is possible to increase the capacity inside the ice making room 40 and the freezing room 50.

  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) exists on the upper projection of the blower fan 90. Further, the axial direction of the blower fan 90 and the front-rear direction of the opening 122b of the damper member 120 are provided substantially in parallel. Therefore, the cool air blown from the blower fan 90 in the centrifugal direction comes into contact with the flapper 121 in the open state of the damper member 120 and is blown to the upper switching chamber 60 located on the front side of the opening 122b. In addition, the support portion 92b of the blower fan 90 or the surface of the holding panel 67 facing the support portion 92b (see FIG. 20), the front surface portion where the opening 122b of the damper member 120 is provided, and the vacuum heat insulating material V11 or the vacuum heat insulating material The holding panel 67 facing the back surface of the V11 is arranged substantially in parallel. Thus, the size of the air passage for guiding the air from the cooler storage space 100 and the air blowing fan 90 in the front-rear direction can be made compact, and the volume of the upper switching chamber 60 can be increased.

FIG. 14 is an exploded perspective view showing the heat insulating partition member.
As shown in FIG. 14, the heat insulating partition member 16 includes a synthetic resin case 160 including a lower case 161 and an upper case 162, a polystyrene foam (so-called styrene foam) 163 as a heat insulating material, and a 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 surface portion 161a at which the outer peripheral edge rises. The side surface portion 161a is formed on all four sides. Further, the lower case 161 has locking claws 161b, 161b formed on opposite sides of the outer surface of the side surface portion 161a.

  The upper case 162 is formed in a rectangular shape, and has a side surface portion 162 a whose outer peripheral edge extends toward the lower case 161. The side surface portion 162a is formed on all four sides. Further, the upper case 162 has a locking hole 162b with which the locking claw 161b is engaged, formed on the opposite side 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. Further, 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 has the same configuration as that of the above-described vacuum heat insulating materials V1 to V8, and is formed in a rectangular shape accommodated in the lower case 161. The vacuum heat insulating material V9 is set to have a thickness such that the surface of the vacuum heat insulating material V9 is located at the upper end of the side surface portion 161a when housed in the lower case 161 together with the expanded polystyrene 163.

  Further, a sealing material 164 is attached to a 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 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 in the lower case 161 and being damaged.

  In such a heat insulating partition member 16, after the expanded polystyrene 163 and the vacuum heat insulating material V9 are stored 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 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 surface portion 162a does not come into contact with the vacuum heat insulator V9, so that the vacuum heat insulator V9 can be prevented from being damaged.

  Further, a double-sided tape 162c is provided on the inner surface of the upper case 162. By bonding the upper case 162 and the vacuum heat insulating material V9 with the double-sided tape 162c, the upper case 162 can be prevented from peeling off from the lower case 161. Further, formation of a gap (space) between the upper case 162 and the vacuum heat insulating material V9 can be suppressed by the double-sided tape 162c, and generation of frost and dew in the gap can be suppressed.

  In the present embodiment, an example is described in which the lower case 161 and the upper case 162 are fixed by fitting the locking claws 161b into the locking holes 162b. However, the present invention is not limited to such a configuration, and the lower case 161 and the upper case 162 may be fixed by 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 that partitions the ice making room 40 and the freezing room 50 into right and left is provided above the heat insulating partition member 16. For this reason, the heat insulating partition member 16 cannot be attached from above, and is attached from below the partition wall 18.

  Also, ribs 11e integral with the inner box 11 are formed on the left and right side surfaces of the inner box 11 so as to protrude, and a hard urethane foam is filled inside (back side) to ensure heat insulation. The upper surface of the end portion of the heat insulating partition member 16 is pressed against the lower side of the rib 11e for positioning, and the fixing member 11f formed as a separate member is pressed against the lower 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, in the vacuum heat insulating material V9, the external dimensions are likely to vary in manufacturing, and the difference between the largest vacuum heat insulating material and the smallest vacuum heat insulating material is widened. Depending on the magnitude of such a difference, heat insulation cannot be performed, and in that case, frost may be generated at the end of the switching chamber (when the temperature is set in the refrigeration zone). Therefore, the tip P2 of the urethane (hard urethane foam) of the rib 11e is located on the inner side (inward) in the left-right direction (width direction) than the position (outer peripheral end P1) where the vacuum heat insulating material V9 has the minimum dimension. ing. In other words, the end of the vacuum heat insulating material V9 and the rib 11e filled with urethane are arranged so as to overlap in the vertical direction. With such an arrangement, it is possible to suppress the risk that the heat insulation is not provided 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.

  When the heat insulating partition member 17 for separating the upper switching chamber 60 and the lower switching chamber 70 is attached, only the upper switching chamber 60 is provided above the heat insulating partition member 17. For this reason, the heat insulation partition member 17 can be attached from the upper side contrary to the heat insulation partition member 16. 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, with respect to the heat insulating partition member 17, the distal end portion P2 of the urethane (hard urethane foam) of the rib 11g is moved in the left-right direction (the outer peripheral end portion P1) of the vacuum heat insulating material V10 (see FIG. 2). (In the width direction). In other words, the end of the vacuum heat insulating material V10 and the rib 11g filled with urethane are arranged so as to overlap in the vertical direction. With such an arrangement, the risk of not being thermally insulated between the upper switching chamber 60 and the lower switching chamber 70 can be suppressed.

  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 box 11. The space between the inner box 11 and the outer box 12 is filled with a foamed heat insulating material. In manufacturing, the outer dimensions are likely to vary during the foaming process. For example, the inner box 11 is deformed so as to swell inside the storage. There are cases. On the other hand, the heat insulating partition member 16 and the heat insulating partition member 17 are not filled with the foamed heat insulating material, so that the external dimensions in manufacturing hardly vary. Therefore, in consideration of the assemblability of the heat insulating partition member 16 and the heat insulating partition member 17 in a predetermined place of the inner box 11, it is possible to provide a gap for absorbing a dimensional tolerance generated after foaming of the foam heat insulating material inside the inner box 11. desirable. At this time, an elastic sealing material (not shown) may be interposed in at least a part of the gap, and the influence of the 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. Note that the same components as those of the heat insulating partition members 16 and 17 shown in FIG. 15 are denoted by the same reference numerals, and redundant description will be omitted.
As shown in FIG. 16, the heat insulating partition members 16 and 17 are made of expanded polystyrene (styrene foam) 163a provided below the vacuum heat insulators V9 and V10, and expanded polystyrene (styrene foam) provided above the vacuum heat insulators V9 and V10. 163b. As described above, the entire periphery of the vacuum heat insulating materials V9 and V10 is covered with the expanded polystyrene 163a and 163b. With such a configuration, the entirety of the vacuum heat insulating materials V9 and V10 are covered, so that 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 is unnecessary. it 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 thermally insulated can be suppressed.

FIG. 17 is a cross-sectional view showing the rear heat 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 that houses the vacuum heat insulating material V11, and a holding panel 67 that holds the housing panel 66. ing. In this embodiment, a case is constituted by the accommodation panel 66 and the holding panel 67.

  The accommodation panel 66 has a bottom surface 66a with which one surface of the vacuum heat insulating material V11 contacts, and a side surface 66b rising from the bottom surface 66a. On the outer surface of the side surface 66b, a locking claw 66c is formed to protrude. Further, 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 it is possible to prevent the vacuum heat insulating material V11 from moving in the accommodation panel 66 and damaging the vacuum heat insulating material V11.

  The holding panel 67 includes a partition plate 67a for partitioning the upper switching chamber 60 and the cooler storage space 100, an upper holding portion 67b for holding an upper portion of the storage panel 66, and a lower holding portion 67c for holding a lower portion of the storage panel 66. And The upper holding portion 67b is formed in a concave shape such that the concave surface opens downward. The lower holding portion 67c is provided with a locking hole 67d for locking the locking claw 66c.

  When attaching the accommodation panel 66 in which the vacuum heat insulating material V11 is housed, the vacuum heat insulating material V11 is attached with the exposed surface facing the holding panel 67 side. In this case, the upper part of the accommodation panel 66 is inserted into the upper holding part 67b first, and the accommodation panel 66 is rotated toward the partition plate 67a using the upper part as a fulcrum. Then, by pressing the storage panel 66 against the partition plate 67a, the locking claws 66c of the storage panel 66 are fitted into the locking holes 67d, and the storage panel 66 is held by the holding panel 67. In this way, by configuring 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, it is possible to prevent water from entering the storage panel 66. When the storage panel 66 is attached to the holding panel 67, the lower holding portion 67c is located outside the side surface 66b, so that the vacuum heat insulating material V11 can be prevented from being damaged.

  By the way, when the upper switching chamber 60 is in the refrigeration temperature zone and the lower switching chamber 70 is in the freezing temperature zone, the upper, lower and back sides of the upper switching chamber 60 are all in the freezing temperature zone. Temperature in the refrigerated temperature zone. Therefore, in the present embodiment, heaters are arranged in the upper switching chamber 60 and the lower switching chamber 70. The details will be described below with reference to FIGS. FIG. 18 is a cross-sectional view showing the arrangement of 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 illustrating an arrangement of a blower fan and a heater provided in a fan casing. FIG. 21 is a cross-sectional view showing a modification of the arrangement of the heaters provided in the blower fan.

  As shown in FIG. 18, the refrigerator main body 10 includes heaters H1, H2, H3, H4, and H5. These heaters H1 to H5 are formed of surface heaters, and serve to increase the temperature or prevent dew. Note that the arrangement and number of heaters described in the present embodiment are merely examples, and are appropriately set according to the heat balance of the upper switching chamber 60 and the lower switching chamber 70.

  The heater H1 is provided on the lower surface of the heat insulating partition member 16 that forms the upper surface of the upper switching chamber 60. The heater H2 is provided on the upper surface of the heat insulating partition member 17 that forms the lower surface of the upper switching chamber 60. The heater H3 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 that forms the bottom surface of the lower switching chamber 70.

  For example, when the upper switching room 60 is set in the refrigeration temperature zone and the lower switching room 70 is set in the freezing temperature zone, heat is assumed to flow from the near side (door side) and the left and right side surfaces of the upper switching room 60, It is assumed that heat flows out of 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 is heated so that the upper switching chamber 60 has a heat balance in the refrigeration temperature zone.

  When the upper switching chamber 60 is set in the freezing temperature zone and the lower switching chamber 70 is set in the refrigeration temperature zone, heat flows in from the near side (door side), the left and right side faces, and the bottom face side of the upper switching chamber 60. It is assumed that heat flows out of the upper and rear sides of the lower 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 has a heat balance in the refrigeration temperature zone.

  19, heaters H6, H7, H8, H9, H10, and H11 are provided on the rear heat insulating partition member 65. These heaters H6 to H11 are configured by surface heaters.

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

  The heater H9 is provided on a wall surface of the fan casing 111. This can prevent frost and water from accumulating in the fan casing 111. The heater H10 is provided near the blower fan 90. This can 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. This can prevent frost from adhering to the inside of the return channel 41b.

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

  The blower fan 90 is fixed to a 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 in a direction 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. It is configured.

  The heater H10 for the blower fan 90 is provided on the blower fan 90 side (outside the warehouse, the fan casing 111 side) of the partition plate 67a. The heater H10 is formed in a disc 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 67a of the rear heat insulating partition member 65 (on the side of the upper switching chamber 60). For example, in the partition plate 67a, at a position facing the blower fan 90, a recessed portion 67e recessed toward the blower fan 90 is formed, and the heater H10 is provided in the recessed portion 67e. By providing the recesses 67e and arranging the heater H10 in this way, there is no hindrance when installing the storage panel 66 (see FIG. 17) provided on the front side of the partition plate 67a.

FIG. 22 is a diagram illustrating an operation panel for switching a temperature zone. The configuration shown below is an example and is not limited to the present embodiment.
As shown in FIG. 22, a control panel (operation panel) 150 is provided, for example, on the surface of the refrigerator compartment door 2 and is electrically connected to the control board 13 (see FIG. 2). Further, the control panel 150 includes a switching operation button 150a for switching the upper switching chamber 60 (switching chamber (upper)) to either the refrigeration temperature zone or the freezing temperature zone, and a temperature zone for displaying whether the temperature is the refrigeration temperature zone or the freezing temperature zone. There is provided a display unit 150b and an intensity display unit 150c for displaying the intensity of the set temperature zone. The control panel 150 is configured similarly to the above for switching of the lower switching chamber 70 (switching chamber (lower)).

  As an operation method, for example, by long-pressing (for example, 5 seconds) the switching operation button 150a, the refrigeration temperature zone and the freezing temperature zone can be switched, and the switched temperature zone is displayed. For example, when the temperature is set to the refrigeration temperature zone, the characters “refrigerated” are displayed on the temperature zone display section 150b, and the characters are lit in green. Further, by short-pressing the switching operation button 150a after switching the temperature zone, "weak", "medium", and "strong" of the intensity display section 150c are sequentially turned on each time the button is short-pressed, and the temperature can be adjusted. it can. For example, it is set to 5 ° C. by setting “weak”, 3 ° C. by setting “medium”, and 1 ° C. by setting “strong”. When the temperature is set to the freezing temperature zone, the text "freezing" is displayed on the temperature zone display section 150b, and the text turns on in blue. As described above, when the temperature zone is switched, by pressing and holding the button, it is possible to prevent the temperature zone from being incorrectly switched.

  Although not shown, a light emitting unit that emits green light and a light emitting unit that emits blue light may be provided in the upper switching chamber door 6 and the lower switching chamber door 7, respectively. When the upper switching chamber 60 is set in the refrigeration temperature zone, the green light emitting section is turned on, and the surface of the upper switching chamber door 6 emits green light. When the temperature is set in the freezing temperature range, the blue light emitting section is turned on, and the display on the upper switching chamber door 6 emits blue light. Further, the lower switching chamber door 7 can be similarly configured. With this configuration, the current temperature zone can be confirmed without the user opening the upper switching room door 6 and the lower switching room door 7.

  Further, since the switching of the temperature zone and the switching of the strength of the switching chamber 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 inexpensive ( For example, the number of switch elements such as capacitance can be reduced), and the simplification of the control panel can reduce the complexity of the operation method and improve the operability.

  Further, the switching operation button 150a, the temperature zone display section 150b, and the intensity display section 150c are lit in a warm color or neutral color when set to the refrigeration temperature zone, and when set to the freezing temperature zone. By lighting in a cool color, the visibility of the user can be improved.

  In addition, in the case of an operation for changing the temperature zone, the temperature zone is not switched just by performing the switching operation, but an operation for prompting the user to determine whether the changed setting is acceptable after the switching operation is added. You may. Thereby, it is possible to more reliably prevent the temperature zone from being incorrectly set.

FIG. 23 is a diagram showing a modification of the arrangement of the control panel.

On the display screen of the portable terminal MT, the current temperature of the upper switching room 60, the current temperature of the lower switching room 70, and the like are displayed. With such a configuration, the current temperature and temperature zone can be confirmed without the user opening the upper switching chamber door 6 and the lower switching chamber door 7. Thereby, the temperature zone can be confirmed without opening the upper switching chamber door 6 and the lower switching chamber door 7.

  The current temperatures of the upper switching room 60 and the lower switching room 70 may be displayed on the surface of the refrigerator compartment door 2 or the like, or may be displayed in the refrigerator compartment 30 (inside the refrigerator).

Light is emitted, and the interior of the refrigerator is illuminated in green. This allows the user to immediately recognize that the upper switching room 60 is in the refrigerated temperature zone (vegetable room) by recognizing green. Further, when the lower switching chamber door 7 is opened, the light emitting section 78b emits light, and the inside of the refrigerator is illuminated with blue. By recognizing blue, the user can immediately recognize that the lower switching room 70 is in the freezing temperature zone (freezing room).

  Further, as shown in FIG. 25B, when the upper switching chamber 60 is set in the freezing temperature zone and the lower switching chamber 70 is set in the refrigeration temperature zone (vegetable compartment), the upper switching chamber door 6 is opened. As a result, the light emitting section 68b emits light, and the inside of the refrigerator is illuminated with blue. By recognizing blue, the user can immediately recognize that the upper switching room 60 is in the freezing temperature zone (freezing room). When the lower switching chamber door 7 is opened, the light emitting section 78a emits light, and the inside of the refrigerator is illuminated in green. By recognizing green, the user can immediately recognize that the lower switching room 70 is in the refrigerated temperature zone (vegetable room).
