Description

  The present invention relates to a refrigerator provided with a glass material on the surface of a refrigerator door.

  As background arts in this technical field, there are JP-T-2005-502854 (Patent Document 1) and JP-A-2006-243421 (Patent Document 2).

  In Patent Document 1, in order to provide a refrigerator having various and high-grade external shapes, a first paint including a reflective material that is formed on a glass member and reflects light that has passed through the glass member as an exterior member of the refrigerator door. It is disclosed to comprise a layer and a second paint layer formed on the first paint layer and having a predetermined color.

  Patent Document 2 discloses a nameplate-forming plate body that can be printed with excellent design, can be produced simply and in large quantities with a high yield, and a manufacturing method thereof. In order to provide this, it is disclosed that a metallic gloss film with printing having a metallic luster and printing is laminated on one side of a transparent substrate via an adhesive layer.

JP 2005-502854 A JP 2006-243421 A

  However, in the configuration described in Patent Document 1, the paint is applied directly to the back surface of the glass member, so that there is a risk of smearing. In addition, since the viscosity and drying time of the paint differ depending on changes in temperature and humidity conditions, fine production management is required to obtain a desired quality of coating.

  Also, when providing multiple paint layers, changing the color tone, or arranging patterns, etc., the next paint is applied after the paint has dried to form multiple paint layers. Therefore, the manufacturing time becomes long and the production efficiency is not high.

  Next, when applying the technology of the nameplate forming plate described in Patent Document 2 to a refrigerator door, the door is filled with a liquid foam heat insulating material such as polyurethane foam in a high temperature state. Therefore, the foam heat insulating material contacts and adheres to the back of the metallic glossy film with print. In this case, at the time of foaming of the foam heat insulating material, the printing surface provided on the printed metallic glossy film and the foam heat insulating material are fixed (strongly bonded). As a result, it becomes difficult to separate and disassemble the transparent substrate to which the metallic glossy film with print is adhered and the foam heat insulating material, the recyclability of the transparent substrate is lowered, and the recycling cost is practically high, and thus it cannot be recycled.

  Furthermore, after the heat insulation of the foam heat insulating material is filled and the heat shrinks, the foam heat insulating material and the metallic glossy film with print are shrunk, and the printed metallic glossy film is torn and wrinkled. Performance may be degraded, and in this case, it will be discarded.

  Then, an object of this invention is to provide the refrigerator which is excellent in design property and is highly recyclable.

  In order to solve the above problems, the present invention provides a door that opens and closes an opening of a storage chamber, a translucent door plate on the surface of the door, a sheet portion on the back surface of the door plate, and a peripheral edge of the door plate. A door frame, an inner wall member supported by the frame with a space from the door plate, a foam insulation material foam filled in the space formed by the inner wall member, the door plate and the frame; The sheet portion includes a decorative sheet that is visually recognized from the front of the door plate, and a partition that partitions the decorative sheet and the foamed heat insulating material.

  ADVANTAGE OF THE INVENTION According to this invention, it is excellent in design property and can provide a refrigerator with high recyclability. Problems, configurations, and effects other than those described above will be clarified by the following description of embodiments.

  Hereinafter, examples will be described with reference to the drawings.

  FIG. 1 is a front view showing the refrigerator according to the first embodiment. In addition, below, it demonstrates on the basis of the direction when the refrigerator 1A is seen from the front.

  As shown in FIG. 1, the refrigerator 1A includes a refrigerator compartment 2, an ice making compartment 3, a switching compartment (upper freezer compartment, quick freezer compartment) 4, a lower freezer compartment 5 (drawer compartment, first storage compartment), and a vegetable compartment 6 ( A drawer chamber, a second storage chamber).

  Further, the refrigerator 1A opens and closes the rotary doors 2a and 2b for opening and closing the refrigerator compartment 2, the drawer type door 3a for opening and closing the ice making chamber 3, the drawer type door 4a for opening and closing the switching chamber 4, and the lower freezer compartment 5 A pull-out door 5a for opening and a pull-out heat insulating door 6a for opening and closing the vegetable compartment 6 are provided.

  FIG. 2 is a schematic structural diagram of the door according to the first embodiment of the present invention. Since the doors 2a and 2b have the same configuration, FIG. 2 shows the door 2a as a representative. The door 2a includes a glass plate (door plate) 10 constituting the front surface, a sheet member 20 to be described later, an inner wall member 30 constituting the surface on the storage chamber side, and a frame body 40 constituting the periphery. A structure is used in which a space formed by the glass plate 10, the inner wall member 30, and the frame body 40 is filled with a foam heat insulating material 50 made of polyurethane foam as an example. The glass plate 10 may be a door plate having translucency such as plastic. Further, a structure in which a vacuum heat insulating material (not shown) is arranged together with the foam heat insulating material 50 can be adopted.

  The specific structure of the door 2a includes a sheet member 20 disposed on the back side of the glass plate 10, an inner wall member 30 configured by sandwiching a foam heat insulating material 50 behind the sheet member 20, and the periphery of the door 2a. And a frame 40 covering the frame. Here, the frame body 40 is a molded product formed of a resin material, and includes an upper frame 41 and a lower frame 42 that constitute upper and lower surfaces, a left frame 43 that constitutes a left side surface, and a right frame that constitutes a right side surface. 44.

  In FIG. 2, the foamed heat insulating material 50 is shown in an exploded perspective view. However, in actuality, it is configured to be in close contact with the back surface of the sheet member 20, the front surface of the inner wall member 30, and the inner surface of the frame body 40. .

  FIG. 3 is a sectional view of the refrigerator door according to the first embodiment of the present invention. In the present embodiment, the glass plate 10 and the sheet member 20 can be simultaneously held by the holding portions 43a and 43b formed in the frame body 40 (43). As specifically illustrated, the left frame 43 has a front holding portion 43a, a rear holding portion 43b, and an inner wall member that hold and hold the sides of the glass plate 10 and the sheet member 20 together. And a holding portion 43c for holding 30. Although not shown, the upper frame 41, the lower frame 42, and the right frame 44 are also provided with the same configuration as the holding portions 43a, 43b, and 43c, respectively, and hold the glass plate 10, the sheet member 20, and the inner wall member 30. doing.

  And the heat insulating door 2a can be formed by filling the space formed between the glass plate 10 including the sheet member 20, the inner wall member 30, and the frame body 40 with the foam heat insulating material 50. .

  The left frame 43 has a structure in which the glass plate 10 and the sheet member 20 are held from the front and rear by the front holding portion 43a and the rear holding portion 43b. However, the holding structure of each frame 40 is not limited thereto. Absent. For example, as shown in FIG. 3B, the structure may be such that the front holding portion 43a of FIG. 3A is eliminated and the glass plate 10 and the sheet member 20 are held by the rear holding portion 43b. Furthermore, the structure which abuts the edge part of the glass plate 10 on the inner surface of the left side frame 43 may be sufficient. Further, in forming the door 2a, each frame body 40 may be a combination of the sandwiching structure and the butting structure. For example, the upper frame 41 and the left frame 43 have a sandwiching structure, and the lower frame 42 and the right frame The frame 44 may have a butting structure. That is, the lower edge and the right edge of the glass plate 10 abut against the frame body 40 (lower frame 42, right frame 44), and the upper edge and the left edge are forward with the frame body 40 (upper frame 41, left frame 43). It is the structure covered.

  Thereby, since the front side is not covered with the frame 40 at least one side, the rectangular glass plate 10 can enlarge the area of the glass plate 10 visually recognizable from the front. In particular, since the right edge and the lower edge are in a position including the central portion of the front surface of the refrigerator 1A, the user can easily recognize the right edge and the lower edge as compared with the left edge and the upper edge. Therefore, by exposing the front sides of the right edge and the lower edge of the glass plate 10, it is possible to give the user an impression as a large-capacity storage space while emphasizing a flat feeling.

  Moreover, in FIG. 1, the right side edge and the lower side edge of the door 2a are in a position closer to the center near the other doors 2b and 3a when the door 2a is closed. On the other hand, the left side edge and the upper side edge of the door 2a are located outside with the door 2a closed. Therefore, there is a possibility that the user and other structures may come into contact with the left edge and the upper edge of the door 2a with the door 2a closed.

  Therefore, the left side edge and the upper side edge of the glass plate 10 located outside are configured to cover the front with the frame body 40, thereby preventing the user and other structures from being directly touched with the door 2a closed. it can. Similarly, the door 2b can achieve the same effect by covering the front side with the frame body 40 on the right edge and the upper edge of the glass plate 10 located outside.

  Here, since the frame 40 is formed by resin molding, an assembly error may occur. In particular, when foaming and filling rigid urethane foam, deformation due to heat or foaming pressure may occur. Under this premise, when the entire periphery of the glass plate 10 is sandwiched between the frame bodies 40, it is assumed that partial stress concentration occurs in the glass plate 10 due to the deformation that occurs during the assembly.

  Therefore, in the present embodiment, the lower edge and the right edge of the glass plate 10 abut against the frame body 40 (lower frame 42, right frame 44), and the upper edge and the left edge are frame bodies 40 (upper frame 41, left frame). 43) the front is covered. Thereby, the deformation | transformation dimension part which arises at the time of an assembly can be absorbed in the location where the lower side edge and right side edge of a right side edge and a lower side edge contact | abut to the frame 40 (lower frame 42, right side frame 44).

  Note that a handle portion (not shown) is provided on the lower frame 42 of the doors 2a and 2b. The handle is formed by a recess, and the user inserts a hand into the gap between the doors 2a and 2b and the pull-out type doors 3a and 4a, and opens and closes the doors 2a and 2b by placing a hand on the recess. By providing the handle portion with the concave portion at the lower part of the door, the flat surface of the glass plate can be shown large in front view, giving the user an impression as a large-capacity storage space.

  In addition, the corner | angular of the glass plate 10 of a present Example is shape | molded at about 90 degree | times. Therefore, when the sheet member 20 is bonded to the glass plate 10, the corners can be aligned, so that positioning is facilitated. Further, when the corners of the glass plate 10 are rounded, the corners of the sheet member 20 may protrude, but in this embodiment, the sheet member 20 can be pasted to the corners of the glass plate 10 with dimensional accuracy. .

  FIG. 4 is a cross-sectional view illustrating a laminated configuration of door plates according to the first embodiment of the present invention. Next, the laminated structure of the glass plate 10, the sheet member 20, and the foam heat insulating material 50 is demonstrated. A sheet member 20 is bonded to the rear side of the glass plate 10 via an adhesive 11. The sheet member 20 according to the present embodiment includes a decorative sheet 21, a paint layer 22 that is a layer of paint printed behind the decorative sheet 21, and a partition sheet 26 that is bonded via an adhesive 25. . Further, a foam heat insulating material 50 is filled behind the sheet member 20. The paint layer 22 includes a decorative layer 23 and an opaque layer 24.

  The decorative sheet 21 may be a thin film-like substrate that can be coated with a paint on the surface, and examples thereof include a polyester film (PET film). The PET film has high transparency, and by printing on the back surface of the base material, it is possible to provide the decorative sheet 21 having a high design with a paint layer visible through the film and a glossy appearance. Moreover, the PET film is excellent in heat resistance and cold resistance, and is less affected by the outside air temperature transmitted from the glass plate. Further, the PET film has excellent strength and is effective in preventing scattering when the glass is broken.

  The decoration layer 23 is for decoration of the door of the refrigerator 1 </ b> A, and is formed by applying a paint to the entire rear surface or a part of the decoration sheet 21. Further, the opaque layer 24 is similarly formed by applying a paint, but is for preventing the rear foam insulation 50 from being seen from the front. When the decoration of the decoration layer 21 is dark and difficult to see through, the opaque layer 22 may not be provided. On the other hand, when the decoration layer 21 is thin and easy to see through, a plurality of opaque layers 22 may be provided. Moreover, it is good also as a structure which does not provide this opaque layer 23 by making the partition sheet 25 mentioned later opaque.

  With respect to the means for printing on the decorative layer 22 and the opaque layer 24, the decorative sheet 21 can be made into a roll-like sheet and can be continuously produced using a rotary printing machine, such as gravure printing, offset printing, flexographic printing. Printing or the like can be employed.

  Silk screen printing (stencil printing) was suitable for applying a paint directly to a hard material such as a glass plate as in the past. However, with this printing means, since ink is pushed out and applied from the holes in the screen, the expression of the decoration is limited by the size of the holes, and a precise expression cannot be made. However, gravure printing, for example, can express fine shades by changing the size and depth of cells on the surface of a printing press, and thus can provide a door plate for a refrigerator with high appearance characteristics.

  Further, when silk screen printing is performed on the back surface of the glass member, smears may occur. In addition, since the viscosity and drying time of the paint differ depending on changes in temperature and humidity conditions, detailed production management is required. Also, when providing multiple paint layers, changing the color tone, or arranging a pattern, etc., the next paint is applied after the paint is dried to form multiple paint layers. The production efficiency was not high.

  However, in this embodiment, since the decorative sheet 21 provided with the coating layer 22 in advance is simply adhered to the back surface of the glass via the adhesive 11, production management is easy and production efficiency can be increased. Further, even if there is a paint mistake or a sheet adhesion mistake, the glass plate can be reused by peeling off the decorative sheet 21 from the glass plate, so the yield is higher than when printing directly on the back of the conventional glass plate. Can be improved.

  However, in this configuration, the heat insulating door of the refrigerator is filled with the foam heat insulating material, so that the paint layer and the foam heat insulating material are bonded. In this case, when the foam heat insulating material is foamed, the paint layer and the foam heat insulating material adhere to each other, so that it becomes difficult to separate and disassemble the glass plate to which the decorative sheet is adhered and the foam heat insulating material, and the recyclability is lowered.

  In some cases, urethane resin is used as the ink resin for gravure printing, and in this case, the resin is more firmly fixed to the foam heat insulating material. In addition, due to the heat shrinkage after filling with the foam heat insulating material, shrinkage may occur while the foam heat insulating material and the decorative sheet are fixed, whereby the decorative sheet may be broken or wrinkled, and the appearance performance may be deteriorated.

  Therefore, in the present embodiment, a partition sheet 26 is provided behind the paint layer 22 to partition the foam heat insulating material 50 via the adhesive 25. By this partition part, it can suppress that the decoration sheet 21 receives the influence at the time of foaming or heat shrink at the time of filling foaming of the foam heat insulating material 50, and can suppress that a tear and a wrinkle are formed. Further, the glass plate 10 and the foam heat insulating material 50 can be easily separated to improve recyclability. Therefore, by adhering the sheet member 20 including the decorative sheet 21 and the partition sheet 26 to the glass plate 10, it is possible to provide a refrigerator with high design and high recyclability. Moreover, in the manufacturing process, by sticking the sheet member 20 to the back surface of the glass plate 10 at a time, production management is easy and production efficiency can be increased.

  Further, when the glass plate 10 is transported or assembled, a protective film may be temporarily provided in order to prevent damage to the glass plate 10 or the paint layer 22. By providing the partition sheet 26, even if the protective film is damaged, the partition sheet 26 is further provided, so that the protection characteristics can be enhanced. Moreover, it is good also as a structure where a partition sheet | seat serves as a protective film in order to reduce cost or improve production efficiency.

  The partition sheet 25 may be a thin film-like material that partitions the paint layer 26 and the foam heat insulating material 50. Specifically, for example, a biaxially stretched polypropylene film (OPP film) may be used. Since the OPP film has excellent heat resistance and strong strength, the coating layer can be protected without being deformed against the high temperature during filling with the foam heat insulating material.

  In addition, the dimension of each structure demonstrated in FIG. 4 does not limit an actual dimension. For example, the partition sheet may be configured such that the width dimension is smaller (thinner) than the decorative sheet. This is because the decorative sheet needs to have a large width dimension in order to further enhance the characteristics of preventing scattering when the substrate material of the paint layer and the glass plate are broken. On the other hand, a partition sheet does not have such a restriction | limiting, A resource can be saved and cost can be reduced by setting it as a thinner structure. As an example of the configuration, a PET film is provided as a decorative sheet and an OPP film is provided as a partition sheet. As an example of the width dimension, PET is approximately 50 microns and OPP is approximately 25 microns.

<Modification 1>
Next, as a first modification of the first embodiment, a configuration in which a sheet member with gradation decoration is provided only on a rotary heat insulating door and a touch type operation unit is provided will be described. In addition, the same site | part, an arrow, etc. are shown with the same code | symbol, and the overlapping description is abbreviate | omitted.

  FIG. 5 is a front view of a refrigerator according to Modification 1 of the present invention. FIG. 6 is a cross-sectional view showing a laminated structure of door plates according to Modification 1 of the present invention. FIG. 7 is a detailed cross-sectional view of the operation / display unit according to Modification 1 of the present invention.

  In the refrigerator 100A shown in FIG. 5, only the rotary doors 2a and 2b that are the upper door 101 are provided with sheet members 110 to be described later with gradation decoration. On the other hand, the lower door 102 composed of the drawer-type doors 3a, 4a, 5a and 6a is decorated by directly applying a paint on the back surface of the glass. The door 2a is provided with an operation / display unit 120.

  As shown in FIG. 6, the sheet member 110 with gradation decoration is provided with a gradation paint layer 111 behind the decoration sheet 21. The gradation paint layer 111 includes at least a gradation layer 112 to which shades of color are applied, and a background layer 113 that becomes a background color of the gradation layer 112. In this embodiment, the two-layer structure of the gradation layer and the background layer is used, but the present invention is not limited to this. Depending on the decoration to be expressed, a decoration layer may be provided on the entire surface of the gradation layer, or a plurality of these layers may be provided.

  A feature of this modification is that only the upper door 101 is provided with a sheet member 101 that can be decorated with higher definition. The upper door 101 is provided at a height position (as an example, a range of 843 mm to 1818 mm from the installation floor) that is easily noticeable by a general user, and has the largest area (however, the right and left doors Therefore, the appearance performance can be effectively improved by changing the color tone or arranging the pattern.

  On the other hand, the lower door 102 is a door at a height position lower than the general user's eye level (as an example, the range of the installation floor to 975 mm), and thus is less visible than the upper door 101. Furthermore, since the decoration is applied to the rear of the thick glass plate 10, the visibility of the decoration becomes worse when viewed straight from the position of the line of sight and when viewed at an angle. Therefore, the lower door 102 may have a single color tone or no pattern. With this configuration, the cost can be reduced by limiting to the upper door 101 which is more effective than the case where the sheet members are provided in all the doors.

  In the present modification, the gradation paint layer 111 of the upper door 101 is configured such that the density of the upper part is the highest and the density gradually decreases toward the lower part, as shown in the doors 2a and 2b in FIG. In a kitchen where a refrigerator is installed, lighting is usually installed at a high position on the ceiling or the like, so that the upper part is well lit and is clearly visible. Therefore, the gradation can be more emphasized by increasing the density of the portion where the light hits well.

  In the present modification, the gradation configuration is shaded in the vertical direction, but is not limited to this. A gradation configuration with shades in the left and right and diagonal directions may be used. Specifically, for example, a configuration in which the left and right sides are dark and the density gradually decreases toward the center may be adopted, and this configuration can give the user a slim feeling.

  In addition, in this modification, although demonstrated in the 6-door type refrigerator, it is not restricted to this. Side-by-side type that has a structure that covers one side of a vertically long storage room with a single door, a three-door type in which the storage space in the refrigerator is divided into three vertically and a two-door type that is divided into two vertically. You may apply to a refrigerator.

  In other words, in a refrigerator equipped with a plurality of doors, at least one door is constituted by a glass plate in which a sheet member provided with a paint layer is pasted on the back surface, and the other door is directly coated with the paint on the glass plate. The configuration. As a result, specific doors can change color or have patterns, and other doors can be configured in a single color or without patterns to attract the user's attention to specific doors while keeping costs down. be able to.

  Next, a configuration provided with an operation / display unit will be described. FIG. 7 is a cross-sectional view showing how the operation / display unit 120 is arranged on the door 2a. The operation / display unit 120 includes a menu display unit 121 printed directly in front of the glass plate 10, a sheet 122 that is a translucent film in which operation content is described with characters, symbols, and the like, and behind this film. An operation / display control unit 123 that is arranged and has a plurality of input touch electrodes and LED light emitting units (none of which are shown), and a sheet 124 and a case 124 that holds the operation / display control unit 123 are laminated. It is a thing. And the sheet | seat 122 and the operation / display control part 123 are integrally hold | maintained at the case 124, and slide the inside of the space formed between the glass plate 10 and the foam heat insulating material 50 of the door 2a by the left-right direction, and thereby the door. 2a is positioned at a predetermined position.

  The menu display unit 121 can be viewed at all times, but the operation display of various operation contents printed on the sheet 122 cannot be viewed normally. When the menu display unit 121 is touched by the user, the LED light emitting unit emits light, and various settings / operation contents and the operation unit of the refrigerator are displayed through the sheet member 110 and the glass plate 10. With this configuration, the content of the sheet member 110 is not displayed on the front surface of the glass plate 10 in a normal state, and the content of the sheet member 110 is lit and displayed when the user needs it. A simple plane can be emphasized and the design can be improved. Furthermore, since the LED emits light only when necessary, power consumption can be suppressed.

  One of the features of this modification is that the menu display unit 121 is provided on the surface of the glass plate 10. When partial printing is provided directly behind the glass plate 10, a gap is formed between the sheet member 110 and the sheet member 110 is peeled off. Further, when the menu display unit 121 is provided by applying paint on the decorative sheet 21 of the sheet member 110, it is necessary to accurately position the sheet member 110 and the operation / display unit 120, resulting in poor production efficiency. .

  In addition, since the menu display unit 121 is an operation unit for lighting the content of the sheet 122, it is necessary for the user to recognize the menu display unit 121, but the menu display unit 121 is provided behind the glass plate 10. In a dark environment, the visibility of the menu display unit 121 is lowered. Therefore, in this embodiment, the menu display unit 121 is provided on the surface of the glass plate 10. Thus, when the user touches the menu display unit 121, the position of the menu display unit 121 can be recognized by the difference in texture between the glass plate 10 surface and the printing surface. In addition, since the sheet member 110 is provided on the back surface of the glass plate 10, the menu display unit 121 can be seen forward from the glass plate 10, and a reduction in visibility due to reflection of the glass plate 10 can be suppressed. .

  Next, Example 2 will be described. Note that parts and arrows similar to those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 8 is a rear perspective view of the door plate according to the second embodiment of the present invention. FIG. 9 is a cross-sectional view illustrating a laminated configuration of door plates according to the second embodiment. FIG. 10 is a cross-sectional view of the refrigerator door according to the second embodiment.

  An opening 201 is formed in a part of the back surface of the sheet member 200. Specifically, the opening 201 is formed by removing a part of the partition sheet 202, for example, by cutting out the vicinity of the four corners in this embodiment, and the coating layer 22 is exposed.

  FIG. 9 shows a stacked configuration of the opening 201. The glass plate 10, the sheet member 200, and the frame of the heat insulating door are temporarily fixed with an adhesive tape (not shown) or the like, and the foam heat insulating material is filled. As a result, the paint layer 22 and the foam heat insulating material 50 are fixed only at the locations of the openings 201. That is, the glass plate 10 is also supported by the foam heat insulating material 50 through the sheet member 200.

  In the present embodiment, as shown in FIG. 10, the frame 203 supports the end portion of the glass plate 10 from the back, and is different from the configuration in which the frame body 203 is sandwiched or abutted as in the first embodiment.

  According to this embodiment, since the frame cannot be seen from the front of the refrigerator main body, the visible area of the glass plate 10 can be widened, so that the flat feeling of the glass plate 10 can be expressed more effectively. it can. Moreover, since the fixing surface with the foam heat insulating material remains at a part (opening 201) at the time of dismantling, the separability is not greatly impaired. In addition, in this embodiment, although it was set as the structure which provides the opening 201 of a recessed part in four corners, it is not restricted to this.

  As mentioned above, according to each Example of this invention, there can exist the following effects.

  That is, a door that opens and closes the opening of the storage chamber, a translucent door plate on the surface of the door, a seat portion on the back surface of the door plate, a frame on the periphery of the door plate, the door plate and the space An inner wall member supported by the frame body with a space therebetween, and a foam heat insulating material foam-filled in a space formed by the inner wall member, the door plate, and the frame body, and the seat portion includes the door A decorative sheet that is visually recognized from the front of the plate; and a partition that partitions the decorative sheet and the foamed heat insulating material.

  Thereby, it can suppress that a decoration sheet receives the influence at the time of foaming or a heat shrink at the time of filling foaming of a foam heat insulating material, and can suppress that a tear and a wrinkle are formed. Moreover, it is easy to separate the door plate and the foam heat insulating material 50, and the recyclability can be improved.

  Further, the door for opening and closing the opening of the storage chamber, the glass plate on the surface of the door, the film part on the back surface of the glass plate, the frame on the periphery of the glass plate, and the glass plate across the space An inner wall member supported by a frame body, and a foam heat insulating material foam-filled in a space formed by the inner wall member, the glass plate, and the frame body, and the film portion includes a decorative sheet and a partition sheet The decorative sheet has a paint layer that is visually recognized from the front of the door plate on the partition sheet side, and the partition sheet is provided at a position that partitions the paint layer and the foam heat insulating material of the decorative sheet. It has been.
