Description

  Embodiments of the present invention relate to a refrigerator.

  Conventionally, in the case of a refrigerator that opens and closes a front opening of a storage room with a pair of kannon doors arranged on the left and right, a rotating partition is provided at the centering portion of both doors, A heater is built in to prevent condensation. In order to prevent the heat generated from the heater from affecting the temperature of the storage chamber, it has been proposed to provide a heat insulating member inside the rotating partition (see, for example, Patent Document 1).

Japanese Patent Laying-Open No. 2015-175584

  However, when the heat insulation performance of the rotating partition is low, not only the heat generation of the heater may affect the temperature of the storage chamber as described above, but also the temperature of the storage chamber may be input to the heater, that is, the heater May affect power consumption. Specifically, when the rotating partition is cooled by the cool air in the storage room that is relatively low in temperature, it is necessary to increase the input to the heater in order to obtain a heat generation amount that can prevent condensation.

On the other hand, when the input to the heater is increased, the effect on the storage chamber is increased, so that it is necessary to cool the storage chamber frequently. That is, when the heat insulation performance of the rotating partition is low, there is a possibility that power consumption increases in both the refrigeration cycle as well as the heater.
Then, the refrigerator which can improve the heat insulation performance of a rotary partition is provided.

  The refrigerator according to the embodiment includes a main body, a pair of left and right doors that open and close a front opening of a storage chamber provided in the main body, a gasket provided on a rear peripheral edge of the door, and one of the doors. A hollow rotating partition which is provided on the door so as to be pivotable, closes between the doors by contacting the gasket of the other door when both doors are closed, and an outer member is formed of a resin material. And a heater provided inside the rotating partition, and a vacuum heat insulating material disposed closer to the storage chamber than the heater inside the rotating partition.

Hereinafter, embodiments will be described with reference to FIGS. 1 to 4.
As shown in FIG. 1, the refrigerator 1 of this embodiment is equipped with the main body 2 which has heat insulation. The refrigerator 1 is provided with a refrigerator compartment 3 and a vegetable compartment 4 in order from the top inside the main body 2, and an ice making room 5 and an upper freezer compartment 6 are provided below the vegetable compartment 4 side by side. A lower freezer compartment 7 is provided in the lower part. Among these, the refrigerator compartment 3 and the vegetable compartment 4 are storage rooms in a refrigeration temperature zone, and the ice making chamber 5, the upper freezer compartment 6, and the lower freezer compartment 7 are storage compartments in a refrigeration temperature zone. As is well known, each storage room of the refrigerator 1 is cooled by a refrigeration cycle (not shown).

  These refrigerator compartment 3, vegetable compartment 4, ice making compartment 5, upper freezer compartment 6 and lower freezer compartment 7 are storage rooms which have a front opening as is well known and the front opening is opened and closed by a door. The refrigerator compartment 3 is provided side by side, and the front opening is opened and closed by a left door 3a that rotates about the left end side and a right door 3b that rotates about the right end side. That is, the refrigerating room 3 is provided with a pair of left and right kannon doors, a left door 3a and a right door 3b, which open and close the front opening of the refrigerating room 3. In the refrigerator compartment 3, a door pocket 3c, a shelf board, and the like are provided as is well known.

  Moreover, as shown in FIG. 2, the back surface of the left door 3a is provided with a gasket 8a for maintaining the airtightness of the refrigerator compartment 3 when closed. Similarly, a gasket 8b is provided on the back surface of the right door 3b to maintain the airtightness of the refrigerator compartment 3 when closed. These gaskets 8a and 8b are formed in a rectangular frame shape along the periphery of the left door 3a and the right door 3b.

  On the other hand, the vegetable room 4, the ice making room 5, the upper freezing room 6 and the lower freezing room 7 are opened to the front by the drawer-type vegetable room door 4a, the ice making room door 5a, the upper freezing room door 6a and the lower freezing room door 7a. Is opened and closed. Although not shown, gaskets 8 are also provided on the back surfaces of the vegetable compartment door 4a, ice making compartment door 5a, upper freezer compartment door 6a and lower freezer compartment door 7a in order to ensure the airtightness of each storage compartment. ing. A permanent magnet is provided inside the gasket 8.

  As shown in FIG. 1, the left door 3 a is provided at its open end, that is, at the end that is the central side of the refrigerator 1, so as to be rotatable with respect to the left door 3 a, and the left door 3 a and the right door 3 b In a state in which both are closed, a rotating partition body 9 is provided that abuts against the gasket 8a and the gasket 8b to airtightly close the refrigerator compartment 3 and each door. The rotary partition 9 is formed longer than the length of the front opening of the refrigerator compartment 3 in the vertical direction.

  That is, the rotary partition 9 is formed in a vertically long shape as shown in FIG. Further, as shown in FIG. 4, the rotary partition 9 has a generally rectangular shape in a cross-sectional view and is formed hollow. Hereinafter, the illustrated vertical direction in FIG. 3 is referred to as a height direction, the horizontal direction in FIG. 4 is referred to as a width direction, and the illustrated vertical direction in FIG. 4 is referred to as a depth direction.

  The rotating partition 9 includes a front plate 10 and a frame 11 that is formed in a substantially C shape in a cross-sectional view and is combined with each other by fitting with the front plate 10 to form a hollow internal space. Yes. Further, as shown in FIG. 3, the rotary partition 9 is provided with a cap member 12 at the upper end on the upper side in the figure and the lower end on the lower side in the longitudinal direction, that is, in the height direction. It is closed.

  The front plate 10 abuts against the gasket 8 of each door in a state where both the left door 3a and the right door 3b are closed, and is exposed to the outside air from the gap between the doors. Further, the frame 11 is generally exposed in the refrigerator compartment 3. The front plate 10, the frame 11, and the cap member 12 are all formed of a resin material. Further, the front plate 10, the frame 11, and the cap member 12 constitute an outer shell member of the rotary partition 9.

A heater 13, a reinforcing plate 14, a magnet 15, and a vacuum heat insulating material 16 are provided in the internal space of the rotating partition 9. The heater 13 is disposed over almost the entire area of the rotary partition 9 in the height direction in contact with the back surface of the front plate 10. Specifically, the heater 13 is disposed so as to go from the upper end side to the lower end side of the rotating partition 9 and to be folded back at the lower end side to reciprocate to the upper end side.
At this time, the forward and return heaters 13 are arranged so that the distance between them is slightly shorter than the gap between the left door 3a and the right door 3b. The heater 13 corresponds to a peripheral member disposed around the vacuum heat insulating material 16 inside the rotary partition 9.

  The heater 13 generates heat by energization and heats the front plate 10 to prevent water droplets from adhering to the surface side of the front plate 10, that is, condensation. In this embodiment, the heater 13 employs a variable pitch having a resistance value that varies depending on the position of the rotary partition 9 in the height direction. For this reason, in the refrigerator 1, the emitted-heat amount in the height direction of a vertical partition differs. In the present embodiment, the pitch is designed so that the amount of heat generation is increased on the upper end side and the lower end side of the rotary partition 9 where condensation is relatively likely to occur. The heater 13 is provided so as to be in close contact with the front plate 10 by the metal tape 17, that is, in a state of being biased toward the front plate 10. The metal tape 17 corresponds to an urging member.

  The reinforcing plate 14 is formed of a metal material in a C shape in a sectional view, and reinforces from one side wall 11b to the other side wall 11b along the back wall 11a. Further, the reinforcing plate 14 is formed to have a length extending over the entire area of the rotary partition 9 in the height direction. The reinforcing plate 14 corresponds to a reinforcing member that suppresses deformation, which will be described later, by reinforcing the frame 11 that is entirely exposed to the refrigerator compartment 3 and exposed to cold air. Further, the reinforcing plate 14 corresponds to a peripheral member disposed around the vacuum heat insulating material 16 inside the rotary partition 9.

  A double-sided tape 18 for fixing the vacuum heat insulating material 16 to the reinforcing plate 14 is provided on the surface of the reinforcing plate 14, that is, the surface on the inner space side. The double-sided tape 18 is provided so as to cover the surface of the reinforcing plate 14, and also functions as a protective member that prevents the vacuum heat insulating material 16 from directly contacting the reinforcing plate 14. The double-sided tape 18 regulates relative movement between the vacuum heat insulating material 16 and the rotary partition 9 and between the vacuum heat insulating material 16 and the reinforcing plate 14, and corresponds to a non-slip member. .

  The magnet 15 is fixed to the position corresponding to the gasket 8 on the inner surface side of the front plate 10 of the rotary partition 9 by an adhesive, tape, or the like. The magnet 15 is provided to have a polarity opposite to that of the magnet 15 on the gasket 8 side. For this reason, when the left door 3a and the right door 3b are closed, the magnet 15 on the rotating partition 9 side and the magnet 15 on the gasket 8 side attract each other, and the rotating partition 9 and the gasket 8 are mutually connected. Airtightness is ensured by pressing. The magnet 15 corresponds to a peripheral member disposed around the vacuum heat insulating material 16 inside the rotary partition 9.

  The vacuum heat insulating material 16 uses, for example, glass wool or the like, which is a thin glass fiber cotton, as a core material, and inserts the core material into a bag member such as a laminate film of aluminum foil and a synthetic resin, and evacuates the inside. By closing the opening, the inside is maintained in a vacuum reduced pressure state. As is well known, the vacuum heat insulating material 16 has a heat insulation performance several times higher in the thickness direction than a foam heat insulating material such as urethane foam having the same thickness.

  In the case of this embodiment, the vacuum heat insulating material 16 has a length that extends over almost the entire region in the height direction of the rotary partition 9 and is formed to a thickness that substantially fills the internal space of the hollow rotary partition 9. Yes. Further, although the refrigerator 1 is not illustrated, a vacuum heat insulating material is also provided on the wall portion of the main body 2, but the vacuum heat insulating material 16 provided on the rotating partition 9 is provided on the wall portion of the main body 2. A bag member having a thickness greater than that of the bag member and an increased strength is employed.

Next, the operation of the above configuration will be described.
As described above, in the rotating partition 9, the front plate 10 is partially exposed to the outside air through the gap between the doors, while being exposed in the refrigerating chamber 3 at a portion located on the inner peripheral side of the gasket 8. ing. For this reason, the front plate 10 is cooled by the cool air in the refrigerator compartment 3, and in that state, condensation occurs at a portion exposed to the outside air. Therefore, it is necessary to heat the front plate 10 with the heater 13.

  Now, when the front plate 10 is heated by the heater 13, the heat is transferred into the refrigerator compartment 3. At this time, in addition to the heat transmitted through the front plate 10, there is also heat transmitted through the frame 11, which is entirely exposed in the refrigerator compartment 3, to the refrigerator compartment 3. For this reason, when the heat insulation performance of the rotary partition 9 is low, the influence on the refrigerator compartment 3 when the heater 13 is heated increases.

  At this time, if the front plate 10 is cooled by the cool air in the refrigerator compartment 3, it is necessary to increase the input to the heater 13 in order to obtain a heat generation amount sufficient to prevent condensation, while increasing the input to the heater 13 The heat transmitted through the front plate 10 and into the refrigerator compartment 3 also increases. As a result, it is necessary to operate the refrigeration cycle frequently. That is, when the heat insulation performance of the rotating partition 9 is low, power consumption may increase in both the heater 13 and the refrigeration cycle.

  Therefore, in this embodiment, the outer shell member of the rotary partition 9, that is, the front plate 10 and the frame 11 are formed of a resin material. Resin materials generally have lower thermal conductivity than metal materials. For this reason, the rotating partition 9 according to the present embodiment, when compared with the conventional one in which the outer shell member is formed of a metal material, transmits heat transmitted to the refrigerating chamber 3 through the front plate 10 when heated by the heater 13. Can be reduced. In other words, the influence of the heat generated by the heater 13 on the temperature in the refrigerator compartment 3 can be reduced.

In addition, although a part of the front plate 10 is exposed in the refrigerator compartment 3, since the thermal conductivity is relatively low, it is possible to reduce the cooling of the front plate 10 from that portion, and input to the heater 13 Can be suppressed from significantly increasing.
Further, since the frame 11 is also formed of a resin material, the heat of the heater 13 is transmitted to the refrigerating chamber 3 through the frame 11, and conversely, the cold air in the refrigerating chamber 3 passes through the frame 11. Thus, the front plate 10 can be prevented from being cooled. And since the cooling of the front board 10 is suppressed, it is suppressed that the input to the heater 13 is increased significantly.

  And inside the rotary partition 9, the vacuum heat insulating material 16 whose heat insulation performance is generally higher than a foam heat insulating material is provided. Thereby, it is suppressed that the heat when the heater 13 generates heat is transmitted to the refrigerator compartment side of the frame 11, and the influence on the temperature of the refrigerator compartment 3 can be further reduced. And if there is little influence on the temperature of the refrigerator compartment 3, since the frequency | count of a refrigerating cycle will also reduce, the increase in power consumption can be suppressed.

  By the way, the rotary partition 9 has a relatively high temperature portion heated by the heater 13 and a relatively low temperature portion because it is exposed in the refrigerator compartment 3. At this time, since the general refrigerator 1 is always energized, the rotary partition 9 always has a high-temperature part and a low-temperature part. In addition, since the outer shell member is formed of a resin material as described above, that is, because the heat insulation performance is improved, a temperature difference is always generated in the outer shell member of the rotary partition 9, There is a possibility that the shell member, that is, the rotary partition 9 is deformed.

  If the rotating partition 9 is deformed, the airtightness cannot be secured and the cool air leaks, the door cannot be closed properly, or even if the cool air leak is prevented, the aesthetic appearance is impaired. Will be. In that case, even if it is a resin material, it is thought that deformation can be prevented by adopting a material having high rigidity, but in that case, the manufacturing cost increases significantly, or the hardness is high but it is weak against impact, There is a risk that the rotating partition 9 may be damaged when it is rotated or when it comes into contact with a container that is put in and out of the refrigerator compartment 3. That is, as a result of forming the rotary partition 9 with a resin material and providing the vacuum heat insulating material 16 with high heat insulating performance, further problems have occurred.

  Therefore, the rotating partition 9 is provided with a reinforcing plate 14 therein. Thereby, a deformation | transformation of the flame | frame 11 currently formed with the resin material can be suppressed. And the deformation | transformation of the front board 10 is also suppressed by the deformation | transformation of the flame | frame 11 being suppressed. As a result, deformation of the rotary partition 9 can be suppressed.

  Further, the reinforcing plate 14 of the present embodiment uses a C-shaped angle material in a sectional view. As described above, the rotary partition 9 is formed to have a length of about several tens of cm that crosses the front opening of the refrigerator compartment 3 in the vertical direction. In this case, if the reinforcing plate 14 is formed in a flat plate shape, the reinforcing plate 14 itself is bent in the length direction, and the deformation of the frame 11 may not be suppressed. Therefore, by forming the reinforcing plate 14 in an L shape, the reinforcing plate 14 is prevented from being bent. Thereby, a deformation | transformation of the rotation partition 9 can be suppressed further.

Now, by providing the reinforcing plate 14, as described above, the deformation of the rotating partition 9 can be suppressed, but the reinforcing plate 14 is often processed by cutting a metal plate, for example. Burr may remain at the cutting site. In this case, it is considered that deburring is performed before being attached to the rotary partition 9, but the cut portion may have a relatively sharp shape even if deburring is performed.
If the position of the vacuum heat insulating material 16 shifts due to vibrations during manufacturing or transportation, the bag member of the vacuum heat insulating material 16 is damaged and the internal vacuum is maintained when it is rubbed against the cut portion of the reinforcing plate 14. There is a possibility that the heat insulation performance will deteriorate.

  Therefore, in this embodiment, the double-sided tape 18 is provided on the surface of the reinforcing plate 14, and the vacuum heat insulating material 16 is fixed by the double-sided tape. The double-sided tape 18 is provided so as to cover the entire surface of the reinforcing plate 14, that is, so that the reinforcing plate 14 and the vacuum heat insulating material 16 do not directly contact each other. Thereby, it is possible to prevent the position of the vacuum heat insulating material 16 from being shifted due to vibration or the like during manufacturing or transportation, and it is possible to suppress damage to the vacuum heat insulating material 16, that is, a decrease in heat insulating performance.

According to the embodiment described above, the following effects can be obtained.
The refrigerator 1 includes a main body 2, a pair of left and right left doors 3a and 3b, and a left door 3a and a right door 3b that open and close a front opening of a refrigerator room 3 (storage room) provided in the main body 2. The gasket 8a is provided on the peripheral edge of the back surface of the left door 3a, and the left door 3a is rotatably provided so that the doors are closed by contacting the gasket 8b of the right door 3b when both doors are closed. The hollow rotating partition 9 in which the outer member is formed of a resin material, the heater 13 provided inside the rotating partition 9, and the refrigerating chamber 3 inside the rotating partition 9 than the heater 13. The vacuum heat insulating material 16 is disposed.

  Since the front plate 10 and the frame 11 (outer shell member) of the rotary partition 9 are formed of a resin material having a lower thermal conductivity than that of metal, the heat of the heater 13 is transmitted to the refrigerating chamber 3, and the refrigerating operation is performed. It can suppress that the heater 13 is cooled with the cool air in the chamber 3. Therefore, the heat insulation performance of the rotary partition 9 can be improved.

  In this case, since it becomes difficult for the heat of the heater 13 to be transmitted to the refrigerator compartment 3, an increase in the temperature in the refrigerator compartment 3 is suppressed, and an increase in the number of operations of the refrigeration cycle can be suppressed. Moreover, since it is suppressed that the heater 13 is cooled by the cold air in the refrigerator compartment 3, the input at the time of supplying with electricity to the heater 13 in order to prevent dew condensation, ie, power consumption, can be suppressed. That is, an increase in power consumption of both the heater 13 and the refrigeration cycle can be suppressed.

  The refrigerator 1 includes a reinforcing plate 14 (reinforcing member) that is provided inside the rotary partition 9 and reinforces the outer member. If the heat insulation of the outer shell member is improved, a portion having a large temperature difference is constantly present in the rotary partition 9, so that there is a risk that the rotary partition 9 may be deformed and airtightness cannot be maintained. is there. Therefore, by providing the reinforcing plate 14 and suppressing the deformation of the rotating partition 9, airtightness can be secured, and the rotating partition 9 can be prevented from being bent to impair the design.

  The refrigerator 1 includes a double-sided tape 18 (anti-slip member) provided between the vacuum heat insulating material 16 and peripheral members such as the heater 13, the reinforcing plate 14, or the magnet 15 disposed around the vacuum heat insulating material 16. Thus, for example, the position of the vacuum heat insulating material 16 in the rotary partition 9 is not shifted during manufacturing or transportation, and the position of the vacuum heat insulating material 16 is stabilized, thereby preventing rubbing between the surrounding members and the like. . Therefore, damage to the vacuum heat insulating material 16, that is, deterioration of the heat insulating performance can be suppressed.

  At this time, the vacuum heat insulating material 16 is fixed by the double-sided tape 18. In the present embodiment, the vacuum heat insulating material 16 is fixed to the reinforcing plate 14 by a double-sided tape 18 provided so as to cover the surface of the reinforcing plate 14. Thereby, for example, the position of the vacuum heat insulating material 16 does not shift during manufacturing or transportation, and rubbing between the vacuum heat insulating material 16 and surrounding members is prevented. Moreover, since it fixes in the state which does not contact the metal reinforcement board 14 with a sharp corner | angular part directly, damage to the vacuum heat insulating material 16 itself can be suppressed.

Moreover, since the vacuum heat insulating material 16 has a thick bag member and increased strength, the risk of breakage is reduced, and the risk of lowering the heat insulation performance is reduced.
The heater 13 has a variable pitch whose resistance value varies depending on the position of the rotary partition 9 in the vertical direction. For this reason, the calorific value is changed in the vertical direction of the rotary partition 9. At this time, it is possible to further suppress the occurrence of dew condensation by designing so that the amount of heat generation is increased on the upper end side and the lower end side of the rotary partition 9 which is relatively liable to cause dew condensation.

(Other embodiments)
Further, the present invention is not limited to the embodiment described above or illustrated in the drawings, and various modifications, expansions, and combinations can be made without departing from the scope of the invention.

  In the embodiment, the example in which the vacuum heat insulating material 16 having a length over the entire region in the height direction of the rotary partition 9 is shown, but the vacuum heat insulating material 16 can be divided into two or more. For example, as shown in FIG. 5, the vacuum heat insulating material 16 can be provided on each of the upper end side and the lower end side of the rotary partition 9. In this case, the vacuum heat insulating material 16 is provided so as to correspond to a portion where the amount of heat generation becomes large when the variable pitch heater 13 is used as in the embodiment, so that the temperature in the refrigerator compartment 3 is increased by the heat of the heater 13. The influence can be suppressed.

  In the embodiment, the vacuum heat insulating material 16 is fixed by the double-sided tape 18. However, as shown in FIG. 6, the vacuum heat insulating material 16 is formed between the vacuum heat insulating material 16 and the outer member such as the frame 11 and is elastic to some extent. You may provide the soft tape 20 which has. In addition, in FIG. 6, illustration of the heater 13, the reinforcement board 14, etc. is abbreviate | omitted for simplification of description.

  Although the vacuum heat insulating material 16 has high heat insulating properties in the thickness direction, the lateral width (length in the left-right direction in FIG. 4) is equal to or less than the width of the rotating partition 9. Therefore, the heat from the heater 13 may be transmitted from the surface of the vacuum heat insulating material 16 to the back surface of the vacuum heat insulating material 16 on the refrigerator compartment 3 side. Therefore, by providing the soft tape 20 between the vacuum heat insulating material 16 and the frame 11, it is possible to suppress the influence on the temperature of the refrigerator compartment 3 due to the heat transmitted through the surface of the vacuum heat insulating material 16.

  At this time, when the thickness of the soft tape 20 is equal to the depth of the internal space (the left-right direction in the figure) when the thickness of the vacuum heat insulating material 16 is added, The vacuum heat insulating material 16 can be urged toward the heater 13 by the soft tape 20 to prevent the displacement of the vacuum heat insulating material 16. That is, the soft tape 20 can function as an urging member. Moreover, since the vacuum heat insulating material 16 is pressed in the direction away from the back wall 11a by the soft tape 20, the influence on the refrigerating chamber 3 by the wraparound of heat from the surface of the vacuum heat insulating material 16 to the back surface can be further reduced. .

  Inside the rotary partition 9, a heat insulating member other than the vacuum heat insulating material 16 can be provided. For example, as shown in FIG. 7, a foam heat insulating material 21 can be provided between the vacuum heat insulating material 16 and the outer member such as the frame 11. Thereby, the influence on the refrigerator compartment 3 by the heat | fever surrounding from the surface of the vacuum heat insulating material 16 as mentioned above to the back surface can be decreased. In this case, by providing the foam heat insulating material 21 not only between the back surface side of the vacuum heat insulating material 16, that is, between the vacuum heat insulating material 16 and the back wall 11a, but also between the vacuum heat insulating material 16 and the side wall 11b, The influence of wraparound can be further reduced. In FIG. 7, illustration of the reinforcing plate 14 and the like is omitted.

  Further, as shown in FIG. 8, the vacuum heat insulating material 16 can be formed with a groove portion 16 a capable of accommodating the heater 13 on the surface on the heater 13 side. Thereby, it can insulate to the circumference | surroundings of the heater 13, and the influence on the temperature in the refrigerator compartment 3 can be reduced. In this case, the depth of the groove 16a is approximately the same as the diameter of the heater 13 or slightly smaller than the diameter, thereby suppressing the thickness of the vacuum heat insulating material 16 from being reduced and excessively reducing the heat insulating performance. it can.

  At this time, for example, with respect to the lower end side of the rotating partition 9 where the heater 13 is folded back in the embodiment, the vacuum heat insulating material 16 reaches beyond the folded portion so that the entire folded portion of the heater 13 can be enclosed. You may form in length. In FIG. 8, the illustration of the reinforcing plate 14 and the like is omitted for simplification of description.

  Further, as shown in FIG. 9, the vacuum heat insulating material 16 can be provided with an escape portion 16 b that avoids surrounding members and surrounding structures disposed around the vacuum heat insulating material 16 inside the rotary partition 9. For example, on the upper end side of the rotary partition 9, there may be a peripheral region 22 in which the circuit of the heater 13 has a peripheral member such as a lead wire or a peripheral structure such as an engaging portion for attaching the cap member 12. . In FIG. 9, illustration of the heater 13, the reinforcing plate 14, and the like is omitted for simplification of description.

And if the vacuum heat insulating material 16 and a surrounding member and a surrounding structure contact, the vacuum heat insulating material 16 may be damaged and heat insulation performance may fall.
Therefore, the vacuum heat insulating material 16 is provided with a relief portion 16b having a stepped shape, for example, from the surface in a cross-sectional view, thereby avoiding contact between the vacuum heat insulating material 16 and the surrounding member or the surrounding structure. Damage, that is, a decrease in heat insulation performance can be suppressed.

  Although the example which heats the front board 10 with the linear heater 13 was shown in embodiment, another heating member can be provided. For example, as shown in FIG. 9, an auxiliary heating member such as a thin plate surface heater 23 can be provided on the back surface of the front plate 10. Since the front plate 10 made of resin material has low heat conductivity, when the heater 13 is not in direct contact with the surrounding region 22, there is a possibility that heating sufficient to prevent dew condensation may not be performed.

  And the upper end and lower end which are the edge parts of the rotary partition 9 are the parts which are easy to condense as mentioned above. Therefore, by providing the thin plate-like surface heater 23 that is relatively unlikely to compete with surrounding members and surrounding structures, the occurrence of condensation can be suppressed by locally heating a portion that tends to form condensation.

  In this case, in the case of the vacuum heat insulating material 16 as shown in FIG. 6, the bag member is extended outward in the longitudinal direction from the core material without being bent at the end in the longitudinal direction of the core material, and the stretched portion Can be brought into contact with the back surface of the front plate 10 as an auxiliary heating member. As described above, since heat is transmitted through the surface of the bag member as described above, it can be used as a thin heat transfer material by intentionally extending the bag member, so that heat can be transmitted to a portion outside the core member. This is because it can.

In the embodiment, the variable pitch heater 13 is used as an example. However, the heater 13 that generates heat uniformly in the height direction of the rotating partition 9 can be used instead of the variable pitch.
In the embodiment, an example in which the reinforcing plate 14 and the magnet 15 are provided inside the rotary partition 9 is shown. However, if the magnet 15 on the gasket 8 side is relatively strong, a flat metal plate is used as the front plate 10. It is possible to adopt a configuration in which the magnet 15 is not disposed. In this case, the metal plate also functions as a reinforcing member that suppresses deformation of the rotary partition 9.

  In the embodiment, the example in which the heater 13 is attached to the front plate 10 side with the metal tape 17 is shown. However, the vacuum heat insulating material 16 can be used as the urging member. For example, the thickness of the vacuum heat insulating material 16 in a state in which no force is applied is added to the thickness of the heater 13, the thickness of the magnet 15, the thickness of the reinforcing plate 14, etc. By forming the value so as to be slightly larger than the thickness of the internal space of the rotary partition 9, the vacuum heat insulating material 16 is accommodated inside the rotary partition 9 in a state compressed in the thickness direction. Thereby, the heater 13 and the magnet 15 can be urged toward the front plate 10 by the vacuum heat insulating material 16. Therefore, the front plate 10 can be efficiently heated, and since the attractiveness with the magnet 15 on the gasket 8 side becomes strong, it becomes easy to ensure airtightness.

  In the embodiment, the C-shaped reinforcing plate 14 is exemplified as the reinforcing member, but the reinforcing member may have other shapes. For example, the reinforcing member can have an L shape that can reinforce the back wall 11a and the side wall 11b. Further, the reinforcing member can be formed into a flat plate shape along the back wall 11a and the side wall 11b of the frame 11, for example.

  Each embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
