Description

  The present invention relates to a refrigerator.

  The refrigerator is provided with doors that are pivotally supported at the left and right ends. In recent years, an increasing number of refrigerator doors cover the front surface with a decorative plate such as a glass plate. As for the door of the said refrigerator, a surrounding surface is a frame part, the back is covered with a cover, and the front is covered with the said decorative board. And a foaming heat insulator is filled in the inside surrounded by the frame part, the cover and the decorative plate. Thereby, a glass plate adheres to a foam heat insulating body.

  In the door using the decorative plate, the frame portion covering the four sides is formed by integrally forming resin. Resin is easily deformed, but has a large thermal deformation. Therefore, when a temperature difference occurs between the front surface and the back surface when the refrigerator is cooled, warpage is likely to occur due to the temperature difference. Due to this warpage, if there is a gap between the door and the refrigerator main body, the cold air escapes, and the cooling performance of the refrigerator deteriorates. In order to suppress such warpage due to the temperature difference of the door, for example, in the refrigerator described in Patent Document 1, a refrigerator is proposed in which a reinforcing member is arranged inside a frame portion that covers the peripheral surface of the door.

Japanese Utility Model Publication No. 61-23272

  The reinforcing member that reinforces the door of the refrigerator described in Patent Literature 1 has a portion that connects the front surface and the rear surface of the frame portion. Thus, since the whole inside of a frame part is reinforced with a reinforcement member, the shape of a frame part may be restrict | limited by the shape of a reinforcement member. In addition, when a reinforcing member that connects the front surface and the rear surface of the frame portion is added, when the temperature difference occurs in the thickness direction of the frame portion, the frame portion is cracked due to the thermal deformation of the frame portion and the deformation difference between the reinforcing member, There is a risk of deformation.

  Then, an object of this invention is to provide the refrigerator provided with the door which can suppress a deformation | transformation and a breakage | damage and can suppress the fall of the cooling performance and cooling efficiency by deformation | transformation of a frame.

  In order to achieve the above object, the present invention provides a refrigerator having a front plate arranged on the front surface of a rectangular door in front view that opens and closes a storage chamber provided in a main body, and has a rectangular shape in front view and a periphery of the front plate. And a reinforcing member attached to the inside of at least one side of the frame, and the frame is formed in a U-shape in cross section and supports the front plate And a rear surface portion facing the front surface portion, a side surface portion connecting the front surface portion and the rear surface portion, and the reinforcing member supports the rear surface portion and the side surface portion, and Located away from the front.

  According to this structure, since the said reinforcement member is supporting the said rear surface part and the said side part, it can suppress the deformation | transformation of the frame of the door which generate | occur | produces with the internal and external temperature difference of the refrigerator when the door is closed. . Thereby, the fall of cooling performance and cooling efficiency can be suppressed.

And the said structure WHEREIN: The said reinforcement member is arrange | positioned away from the said front surface. Thereby, since there is a predetermined distance between the front surface of the frame body and the reinforcing member, it is possible to secure a region that absorbs deformation of the side surface due to a temperature difference between the front surface and the rear surface of the frame body. . Therefore, it is possible to prevent the side surface portion of the frame body from being locally deformed, and it is possible to prevent damage such as breaking of the side surface portion of the frame body.

  In addition, the said reinforcement member may be provided in the back surface part side rather than the center of the front-back direction of the said side part. By constructing in this way, the reinforcement of the side surface part that generates a temperature difference in itself is limited to the rear surface part side, which is a necessary range, thereby securing a region to absorb the stress generated by the thermal deformation of the side surface part. It is possible to reduce the stress by dispersing it over a wider area, thereby suppressing excessive deformation and breakage of the side surface.

  The said structure WHEREIN: The said reinforcement member may be provided in the adjacent edge | side of the said frame, and the clearance gap may be provided between the said reinforcement members in this case. The reinforcing member may be attached to all four sides of the rectangular frame.

  The said structure WHEREIN: The said side part may be comprised by the surface from which the part adjacent to the said rear surface part and the part adjacent to the said front surface part differ. The portion adjacent to the rear surface portion reinforced by the reinforcing member is preferably a flat surface to be supported by the reinforcing member. Moreover, it is preferable that the part adjacent to the front part which accept | permits a certain amount of deformation | transformation is a curved surface which a deformation | transformation does not stand out easily.

  In the above configuration, the frame body includes a support protrusion that supports the reinforcing member, and the support protrusion protrudes inward and elastically deforms, and a direction intersecting from the tip of the protrusion The reinforcing member may be supported by the frame body by contacting the presser portion. By comprising in this way, a frame and a reinforcement member can move relatively in the longitudinal direction of a reinforcement member. Thereby, even if the thermal contraction difference between the frame body and the reinforcing member occurs, they are not pulled from each other, so that the stress due to heat can be suppressed.

  The said structure WHEREIN: Even if the inside of the said door is filled with the heat insulation foam and the peeling layer which peels the said heat insulation foam is provided at least between the said rear surface part or side part, and the said reinforcement member, Good. By comprising in this way, the said rear surface part or side part and the said reinforcement member can be suppressed by the heat insulation foam.

  In the above configuration, the door is pivotally supported by the main body at least in the vicinity of one of the left and right sides, and the reinforcing member is provided on the pivoted side of the left and right sides of the frame. Good.

(First embodiment)
FIG. 1 is a front view of an example of a refrigerator according to the present invention. In the following description, the front-rear direction, the up-down direction, the left-right direction, and the like may be indicated. In this case, the state shown in FIG. In the refrigerator A, the refrigerator compartment 1 is provided on the upper part of the main body 100 including the heat insulating box. Below the refrigerating room 1, an ice making room 2 and an upper freezing room 3 are arranged side by side. A lower freezing chamber 4 is provided below the ice making chamber 2 and the upper freezing chamber 3.

  The refrigerator compartment 1 stores stored items in a refrigerator. The ice making chamber 2 performs ice making and ice storage. The upper freezer compartment 3 and the lower freezer compartment 4 store the stored items in a frozen state. In the present embodiment, the upper freezer compartment 3 is a freezer compartment, but the maintenance temperature may be changed. By changing the maintenance temperature, it can be used as, for example, a refrigerating room or a storage room other than the freezing room.

  The refrigerator compartment 1 is opened and closed by a door 11. The door 11 is rectangular when viewed from the front, and includes a left hinge portion 111 and a right hinge portion 112 at both left and right end portions (see FIG. 6 described later). As shown in FIG. 6, the left hinge portion 111 and the right hinge portion 112 are formed on the upper side and the lower side of the door 11.

  On the front surface of the door 11, a left handle 12 and a right handle 13 are provided. The right hinge portion 112 is pivotally supported by pulling the left handle 12. As a result, the door 11 pivots around the axis (not shown) of the right hinge portion 112. Moreover, the left hinge part 111 is pivotally supported by pulling the right handle 13. Thereby, the door 11 rotates effortlessly on the axis | shaft (not shown) of the left hinge part 111. As shown in FIG. In addition, when the door 11 is in a closed state, one of the left handle 12 and the right handle 13 can be operated. By pulling either one, the opposite side of the pulled handle is used. The hinge part acts to open the door. The operations of the left handle 12 and the right handle 13, and the right hinge portion 112 and the left hinge portion 111 are well known and will not be described in detail.

  The ice making chamber 2 is opened and closed by a drawer-type door 21 integrated with an ice storage container (not shown). The upper freezer compartment 3 and the lower freezer compartment 4 are respectively opened and closed by drawer-type doors 31 and 41 integrated with a storage case (not shown) of stored items. The doors 11, 21, 31, and 41 are filled with a foam insulation 50 (see FIG. 5). Since the main body 100 is a heat insulating box, when the doors 11, 21, 31 and 41 are closed, the refrigerator compartment 1, the ice making compartment 2, the upper freezer compartment 3 and the lower freezer compartment 4 are insulated from the outside, respectively. Space.

  FIG. 2 is a front view of the refrigerator compartment door shown in FIG. 3 is a cross-sectional view of the door shown in FIG. 2 taken along line III-III. 4 is a cross-sectional view of the door shown in FIG. 2 taken along line IV-IV. FIG. 5 is an enlarged view of a circled portion of the door shown in FIG. FIG. 6 is a perspective view of the frame constituting the door as seen from the lower rear side. FIG. 7 is an enlarged view of a circled portion of the frame shown in FIG. FIG. 8 is a cross-sectional view of the frame shown in FIG. 6 taken along line VIII-VIII. FIG. 9 is an enlarged view of a portion surrounded by a circle on the upper side of the frame shown in FIG. FIG. 10 is an enlarged view of a circled portion on the lower side of the frame shown in FIG.

  As shown in FIGS. 2 and 3, the door 11 includes an upper frame 14, a left frame 15, a right frame 16, a lower frame 17, a glass plate 18 (front plate), and a back cover 19. The upper frame 14, the left frame 15, the right frame 16, the lower frame 17, and the rear cover 19 are resin moldings, and cover the upper surface, the lower surface, the left and right side surfaces, and the rear surface of the door 11, respectively. The glass plate 18 is formed of, for example, soda glass having a thickness of 3.2 mm and covers the front surface of the door 11. The door 11 has a space covered with an upper frame 14, a left frame 15, a right frame 16, a lower frame 17, a glass plate 18 and a back cover 19. The space is filled with a heat insulating foam 50 (see FIG. 5 and the like).

  The door 11 has a rectangular shape, and the upper frame 14 and the lower frame 17, and the left frame 15 and the right frame 16 form a pair. That is, the upper frame 14 and the lower frame 17 have substantially the same configuration. Moreover, although the left frame 15 and the right frame 16 are in a mirror image relationship, other than that, they have the same structure.

  When the door 11 is opened and closed around the axis of the left hinge part 111 or the axis of the right hinge part 112, the upper frame 14 and the lower frame 17 support the weight of the door 11. In order to suppress deformation of the upper frame 14 and the lower frame 17 due to the weight of the door 11, a reinforcing member 141 is provided on the inner surface side of the upper frame 14. Similarly, a reinforcing member 171 is provided on the inner surface side of the lower frame 17. The reinforcing member 141 and the reinforcing member 171 have a sufficient size capable of suppressing deformation of the upper frame 14 and the lower frame 17 and are firmly fixed.

  By arranging such reinforcing members 141 and 171, even if the door 11 is supported in a cantilevered state by the left hinge portion 111 or the right hinge portion 112, it is possible to prevent the door 11 from being deformed or damaged. . The upper frame 14 and the lower frame 17 include a front surface portion and a rear surface portion.

  The left frame 15 has a front surface portion 153, a rear surface portion 154, and a side surface portion 155, and is formed in a U-shaped cross section. The left frame 15 is provided with a reinforcing member 151 on the inner surface. As shown in FIG. 8, the reinforcing member 151 is a long member, and the reinforcing member 151 is disposed on the inner surface side of the left frame 15 along the longitudinal direction. As shown in FIG. 5, the reinforcing member 151 is formed in a U-shaped cross section, and includes a bottom wall portion 1511 that is supported by contacting the side surface portion 155, and a rear wall portion that is supported by contacting the rear surface portion 154. 1512 and a front wall portion 1513 facing the rear wall portion 1512. The bottom wall portion 1511, the rear wall portion 1512 and the front wall portion 1513 are integrated.

  In this embodiment and other embodiments described later, the bottom wall portion 1511 of the reinforcing member 151 is in contact with the side surface portion 155 of the frame, and the rear wall portion 1512 of the reinforcing member 151 is in contact with the rear surface portion 154 of the frame. The member 151 supports the left frame 15, but may have a gap without contact, or may have a contact portion and a portion having a gap. Moreover, when it has a clearance gap, it is preferable that the reinforcing member 151 can support the frame.

  A stopper 156 that protrudes inward is formed at a portion of the rear surface portion 154 away from the side surface portion 155. The stopper 156 is a ridge formed continuously in the longitudinal direction of the rear surface portion 154 (see FIGS. 9 and 10). The stopper 156 is formed in a wedge shape having an inclined surface with a thin tip. The stopper 156 is in contact with the end of the rear wall 1512 of the reinforcing member 151 opposite to the bottom wall 1511 and supports the reinforcing member 151.

  A support protrusion 152 is provided inside the side surface portion 155 of the left frame 15. The support protrusions 152 are arranged at predetermined intervals in the longitudinal direction of the left frame 15. Note that the support protrusions 152 may be arranged at equal intervals, or the number of the support protrusions 152 may be changed according to the force distribution. The support protrusion 152 is disposed at a distance equal to or slightly larger than the front-rear width of the reinforcing member 151 with respect to the rear surface portion 154 (see FIGS. 3 and 8).

  As shown in FIG. 5, the support protrusion 152 includes a flat plate-like protruding portion 1521 that protrudes inward from the inner surface of the side surface portion 155, and a presser portion 1522 that protrudes toward the rear surface portion 154 on the distal end side of the protruding portion 1521. I have. The protrusion 1521 can be elastically deformed and bends when a force acts on the tip. Further, the presser portion 1522 has a wedge shape having an inclined surface whose tip is narrowed. The pressing portion 1522 is in contact with the end portion of the front wall portion 1513 of the reinforcing member 151 opposite to the bottom plate portion 1511 and supports the reinforcing member 151.

  The interval between the stopper 156 and the pressing portion 1522 is narrower than the front-rear width of the reinforcing member 151. The bottom wall portion 1511 of the reinforcing member 151 is brought into contact with both the stopper 156 and the pressing portion 1522 of the support protrusion 152 and then pressed toward the side surface portion 155. At this time, the reinforcing member 151 is pushed by the inclined surface of the stopper 156 and displaced forward. In the support protrusion 152, the inclined surface of the pressing portion 1522 is pressed by the reinforcing member 151, and the protruding portion 1521 is elastically bent. As a result, the distance between the stopper 156 and the pressing portion 1522 is widened, and the bottom wall portion 1511 of the reinforcing member 151 enters between the stopper 156 and the pressing portion 1522. When the reinforcing member 151 is further pushed, the rear wall portion 1512 moves to the side wall portion 155 side with respect to the stopper 156, and the front wall portion 1513 moves to the side wall portion 155 side with respect to the presser portion 1522, the protruding portion 1521 becomes the original. Return to shape. As a result, the rear wall portion 1512 engages with the stopper 156 and the front intermediate portion 1513 engages with the presser portion 1522, and the reinforcing member 151 is supported by the left frame 15.

  When the reinforcing member 151 is attached to the left frame 15, the bottom wall portion 1511 of the reinforcing member 151 is in contact with the side surface portion 155 and the rear wall portion 1512 is in contact with and supported by the rear surface portion 154. Thereby, the reinforcing member 151 reinforces the rear surface portion 154 side surface portion 155. When the reinforcing member 151 is attached to the left frame 15, the bottom wall portion 1511 and the side surface portion 155 of the reinforcing member 151, and the rear wall portion 1512 and the rear surface portion 154 are relatively movable in the longitudinal direction of the reinforcing member 151. It has become. The reinforcing member 151 is provided on the rear side of the center of the left frame 15 in the front-rear direction. That is, the reinforcing member 151 is separated from the front surface portion 153 of the left frame 15. In the left frame 15 shown in FIG. 5, the reinforcing member 151 is provided on the rear side of the center C1 in the front-rear direction.

  The left frame 15 is provided with a hook 157 further on the front side of the front surface 151. The hook 157 holds the glass plate 18 by sandwiching the peripheral portion between the front surface portion 153 and the glass plate 18. The hook 157 covers the edge portion of the glass plate 18.

  As shown in FIG. 4, the right frame 16 is bilaterally symmetric with the left frame 15, but has the same configuration. That is, the support member 161 is provided on the inner surface. The right frame 16 includes a support protrusion 162, a front surface portion 163, a rear surface portion 164, and a side surface 165 (see FIG. 4). In addition, although illustration is abbreviate | omitted, the vinegar stopper and the hook are also provided. The details of the right frame 16 are the same as those of the left frame 15 and are omitted.

  As shown in FIG. 6, a frame 110 is configured by combining an upper frame 14, a left frame 15, a right frame 16, and a lower frame 17 in a rectangular shape. In the following description, when the upper frame 14, the left frame 15, the right frame 16, and the lower frame 17 are used in combination, the frame body 110 will be described.

  In the door 11, the glass plate 18 is a rectangular plate arranged on the front surface of the frame body 110. The peripheral edge of the glass plate 18 is in contact with the front surface of the upper frame 14, the front surface 153 of the left frame 15, the front surface 163 of the right frame 16, and the front surface of the lower frame 17. Further, hooks 157 of the left frame 15 and hooks of the right frame 16 are respectively engaged with the front side of the long side of the glass plate 18. The door 11 is configured to rotate around either the left hinge portion 111 or the right hinge portion 112. Therefore, the left and right ends of the glass 18 easily collide with furniture or the like (a chair or a wagon). Since the left and right ends of the glass plate 18 are covered with the hooks 157 of the left frame 15 and the hooks of the right frame 16, the edges of the glass plate 18 are protected, and damage to the glass plate 18 can be suppressed.

  The back cover 19 constitutes the interior of the refrigerator compartment 1. The peripheral edge portion of the back cover 19 contacts the rear surface portion of the upper frame 14, the rear surface portion 154 of the left frame 15, the rear surface portion 164 of the right frame 16, and the rear surface portion of the lower frame 17, and is fixed to each rear surface portion. When the door 11 closes the refrigerator compartment 1, the peripheral edge of the back cover 19 comes into contact with the main body 100. If there is a gap between the back cover 19 and the main body 100, the external high-temperature air flows into the inside, in other words, the internal cooled air flows out to the outside. Therefore, an elastically deformable packing 191 is provided at the peripheral edge of the back cover 19. When the door 11 closes the refrigerator compartment 1, the packing 191 is elastically deformed and hermetically seals the refrigerator compartment 1. Thereby, when the door 11 is in the closed state, the flow of air inside and outside the refrigerator compartment 1 is suppressed.

  The door 11 is filled with the heat insulating foam 50 in a space surrounded by these members with the glass plate 18 attached to the front surface of the frame 110 and the back cover 19 attached to the rear surface. And since the heat insulation foam 50 solidifies, the frame 110, the glass plate 18, and the back cover 19 are integrated. In addition, when fixing of the glass plate 18 is required at the time of manufacture (especially the process of filling with a heat insulating foam), at least one front portion of each frame of the frame 110 and the glass plate 18 are bonded with an adhesive or a double-sided tape. Etc. may be used for bonding.

  The door 11 is filled with a heat insulating foam 50 in a space surrounded by the frame 110, the glass plate 18, and the back cover 19, and the door 11 becomes a heat insulator. The heat insulating foam 50 serves as an adhesive that integrates the glass plate 18 and the frame 110, and the back cover 19 and the frame 110. Furthermore, the solidified heat insulating foam 50 also serves as a strength member of the door 11.

  Further details of the reinforcing member will be described. When the door 11 closes the refrigerator compartment 1, the refrigerator compartment 1 has a temperature lower than the outside. Therefore, the door 11 has a temperature difference between the front surface and the rear surface. Also in the frame 110 itself, there is a temperature difference before and after. As described above, the frame 110 is made of resin, and deformation (expansion or contraction) due to heat is larger than that of a material such as metal. The frame 110 has a difference in deformation amount between the front side and the rear side due to a temperature difference between the front and rear.

  The door 11 has a rectangular shape that is long in the vertical direction. Of the frame body 110 surrounding the outer periphery of the door 11, the upper frame 14 and the lower frame 17 have a short length in the longitudinal direction, so that the difference in deformation is small, and problems due to the difference in deformation are unlikely to occur. As described above, since the upper frame 14 and the lower frame 17 are also members that support the weight of the door 11, the reinforcing member 141 and the reinforcing member 171 are disposed so as to reinforce the entire upper frame 14 and lower frame 17, respectively. Has been.

  On the other hand, in the frame body 110, the left frame 15 and the right frame 16 are longer in the longitudinal direction than the upper frame 14 and the lower frame 17, and thus the difference in deformation amount between the front and rear due to the temperature difference between the front and rear becomes large. For example, if the refrigerator A is used in a high temperature environment, the front surface 153 side of the left frame 15 expands due to the outside air temperature, and the rear surface 154 side contracts due to the cold air in the refrigerator compartment 1. That is, when the article is cooled in the refrigerator compartment 1, the front surface portion 153 side is at a high temperature and the rear surface portion 154 is at a low temperature. The rear surface portion 154 is shorter than the length of the front surface portion 153. That is, in the deformation of the left frame 15, the middle part in the vertical direction is bent forward.

  When the left frame 15 is deformed as described above due to the temperature difference between the front and rear, the rear part 154 and the side part 155 are problematic as the refrigerator A. If the middle part of the rear surface part 154 in the vertical direction is bent forward, a gap is formed between the door 11 and the main body part 100. Since this gap is formed, the refrigerator compartment 1 is not sufficiently sealed, and the cooling efficiency may be reduced or the cooling may be insufficient.

  Further, the side surface portion 155 has a configuration in which the front surface portion 153 and the rear surface portion 154 are connected to each other, and a temperature difference is generated in itself, and a difference in deformation occurs between the front side and the rear side. As described above, when a difference in deformation amount occurs, deformation, cracking, and the like are likely to occur.

  Therefore, the left frame 15 is provided with a reinforcing member 151 to suppress deformation of the rear surface portion 154 and the side surface portion 155 due to temperature change. Details of the left frame 15 and the reinforcing member 151 will be described. The reinforcing member 151 is made of a metal material (for example, iron). Therefore, the reinforcing member 151 is less likely to be deformed by heat than the left frame 15.

  As shown in FIG. 5, the reinforcing member 151 is pressed and supported by a stopper 156 and a pressing portion 1522 of the support protrusion 152. That is, the rear wall portion 1512 and the rear surface portion 154 of the reinforcing member 151 and the bottom wall portion 1511 and the side surface portion 155 of the reinforcing member 151 come into contact with each other but are not fixed. For this reason, even if a shrinkage difference occurs between the rear surface portion 154 and the rear wall portion 1512 due to thermal deformation, the rear surface portion 154 and the rear wall portion 1512 are relatively displaced, so that the generation of stress is suppressed. Similarly, even if a shrinkage difference occurs between the side surface portion 155 and the bottom wall portion 1511 due to thermal deformation, the side surface portion 155 and the bottom wall portion 1511 are relatively displaced in the longitudinal direction, and thus the generation of stress is suppressed. . That is, even if the rear surface portion 154 and the side surface portion 155 expand or contract in the longitudinal direction, the generation of stress with the reinforcing member 151 is suppressed.

  Further, since the reinforcing member 151 has a U-shaped cross section including a bottom surface portion 1511 that connects the rear wall portion 1512 and the front wall portion 1513, the reinforcing member 151 is not easily bent in the front-rear direction. Thereby, even if the rear surface portion 154 and the side surface portion 155 of the left frame 15 are deformed as described above, the reinforcing member 151 suppresses the deformation of the rear surface portion 154 and the side surface portion 155. Therefore, even if the above-described deflection due to the temperature difference occurs in the rear surface portion 154 and the side surface portion 155, the deformation is suppressed by the reinforcing member 151. As described above, the reinforcing member 151 is formed of a metal such as iron and generally has a larger elastic coefficient than that of the resin. Also from this, the reinforcement member 151 exhibits the effect which suppresses the above deformation | transformation by the temperature difference of the rear surface part 154 and the side part 155. FIG.

  The front wall portion 1513 of the reinforcing member 151 is provided with a space from the front surface portion 153. From this, the rear surface portion 154 of the left frame 15 is restricted in deflection by the reinforcing member 151, but the reinforcement by the reinforcing member 151 is separated from the front surface portion 153.

  The side surface portion 155 is provided with a rear portion S1 and a front portion S2. The rear portion S1 of the side wall portion 155 comes into contact with the bottom wall portion 1511 and is reinforced. Since the bottom wall portion 1511 of the reinforcing member 151 has a planar shape, the rear portion S1 reinforced by the bottom wall portion 1511 is a plane. Deformation of the rear portion S1 of the side surface portion 155 is suppressed by the reinforcing member 151.

  On the other hand, the front portion S2 is a portion that allows deformation to some extent due to a temperature difference, and is different from the plane of the rear portion S1. Note that when the deformation is different in the lateral direction as in the side surface portion 155, the curved surface is less likely to be visually recognized by the user than the flat surface, that is, the surface is less noticeable. Therefore, the front side portion S2 of the side surface portion 155 is a curved surface. If the deformation is not noticeable, it may be a flat surface. In that case, it may be the same plane as the rear portion S1 or a different plane.

  In the side surface portion 155, deformation of the rear portion S1 is restricted, and deformation of the front portion S2 is allowed to some extent. Therefore, distortion caused by the deformation of the rear portion S1 is dispersed by the deformation of the front portion S2. The front portion S2 has a curved surface structure in which a predetermined range of deformation is difficult to be visually recognized. Thereby, compared with the case where the deformation of the entire surface of the side surface portion 155 is restricted, the deformation amount can be suppressed and the deformation can be made inconspicuous. In addition, the front surface part 153 of the left frame 15 is in contact with the glass plate 18, and the glass plate 8 has a smaller amount of thermal deformation than the resin. Therefore, it can be considered that the front surface portion 153 is reinforced by the glass plate 18.

  The right frame 16 has the same configuration as the left frame 15.

  As described above, in the frame 110, the upper frame 14, the left frame 15, the right frame 16, and the lower frame 17 and the reinforcing members 141, 151, 161, and 171 provided in the respective frames are different materials. The amount of deformation due to heat is different. When the reinforcing members 141, 151, 161, and 171 are connected to each other in the frame, stress is generated due to the difference between the deformation amount of the upper frame 14, the left frame 15, the right frame 16, and the lower frame 17 during thermal deformation. Cause damage. Therefore, the reinforcing member 151 provided on the left frame 15 constituting the long side of the frame 110 and the reinforcing member 161 provided on the right frame 16 constituting the long side are respectively referred to as the left frame 15 and the right frame 16. Is also formed short.

  7 and 9, when the upper frame 14 and the left frame 15 are joined, the reinforcing member 141 provided on the upper frame 14 and the reinforcing member 151 provided on the left frame 15 are joined. A gap Gp is provided. It is assumed that the door 11 is cooled and the left frame 15 and the reinforcing member 151 are contracted by providing the gap as described above. As the left frame 15 contracts, the upper frame 14 joined to the left frame 15 moves downward. At this time, a shrinkage difference due to temperature occurs between the left frame 15 and the reinforcing member 151, but by providing the gap Gp, the reinforcing member 141 of the upper frame 14 and the reinforcing member 151 of the left frame 15 come into strong contact. Can be suppressed. As a result, it is possible to suppress the left frame 15 from being stressed due to thermal deformation (shrinkage due to cooling) and being deformed or damaged.

  On the other hand, as shown in FIG. 10, the reinforcing member 151 and the reinforcing member 171 are in contact with each other at the joint portion between the left frame 15 and the lower frame 17. This is because the weight of the door 11 is applied to the lower frame 17 and the reinforcing member 171. Therefore, the upper frame 14 and the left frame 15 are brought into contact with each other in order to perform stronger reinforcement. The reinforcing member 151 of the left frame 15 has a gap Gp between the reinforcing member 141 of the upper frame 14 and the left frame 15 and the reinforcing member 151 are relative to each other in the longitudinal direction of the left frame 15 (that is, the vertical direction). Can be moved. Therefore, the difference in shrinkage due to temperature changes between the left frame 15 and the reinforcing member 151 can be adjusted by the gap Gp.

  From the above, it is preferable that the gap Gp is larger than the difference in deformation amount between the left frame 15 and the reinforcing member 151 generated by an assumed temperature change. Further, also in the left frame 16, a gap Gp is provided between the reinforcing member 141 and the reinforcing member 161 at a joint portion with the upper frame 14.

The heat-insulating foam 50 may be in close contact with the member when cured and perform the same function as an adhesive. Since the heat insulating foam 50 is liquid when filled, it enters between the rear surface portion 154 and the rear wall portion 1512 or between the side surface portion 155 and the bottom wall portion 1511. As a result, the rear surface portion 154 and the rear wall portion 1512, the side surface portion 155 and the bottom wall portion 1511 are fixed so as not to move, and stress is generated during thermal deformation.

The thing of the cross-sectional shape which contacts the rear surface part 154 and the side part 155, and suppresses a deflection | deviation can be employ | adopted widely.

  Further, the support of the reinforcing member 151 by the left frame 15 is performed using a support protrusion 152 (so-called snap fit) that is elastically deformed by being pushed in, but is not limited thereto. A support method in which the rear wall portion 1512 and the rear surface portion 154 of the reinforcing member 151 and the bottom wall portion 1511 and the side surface portion 155 are relatively movable in the longitudinal direction of the reinforcing member 151 can be widely employed.

  According to the refrigerator A shown above, it is possible to suppress the occurrence of warpage or breakage even if a difference in deformation occurs between the front and back of the door due to the temperature difference between the inside and outside. With the door closed, the storage room can be hermetically sealed to prevent the air inside and outside the refrigerator A from being exchanged. Thereby, it is possible to suppress that the cooling capacity of the refrigerator A falls or cooling efficiency falls.
