However, since the substrate support and the glass plate in Patent Document 1 are not positioned in the left-right direction with respect to the horizontal frame, the relative positions of the light sources installed on the substrate support with respect to the glass plate are the substrate support and the glass. It may change as the board moves in the left-right direction. If the light source portion is displaced outside the translucent portion of the glass, the display may appear lacking or the light may bleed into a display that should not be shining. In order to prevent this, it is necessary to set the translucent portion of the glass larger than the light source in consideration of the positional deviation. For this reason, in Patent Document 1, each display illustration provided on the glass plate corresponding to each light source needs to have a large translucent portion, and therefore must be positioned apart from each other. There was a problem that the design of the display part was restricted.

Therefore, an object of the present invention is to provide a refrigerator in which the design of the display portion on the outer panel of the heat insulating door is improved.

In the refrigerator of the present embodiment, a light-transmitting glass plate 7 is provided on the outer surface of each door as a door front plate (door front member) (see FIG. 2). Further, a substrate assembly 21 described later is arranged on the back side of the refrigerator compartment door 2b to form a display unit 50. Further, as shown in FIG. 5, the foamed heat insulating material (heat insulating material) 9 is filled and foamed between the door front plate (door front member) 7 and the door back member 10 using the glass plate 7 as an example. The plate thickness of the glass plate 7, which is the door front plate 7, is 2 mm to 3.5 mm in the present embodiment. This plate thickness is a dimension at which the glass plate 7 is not cracked or cracked due to an impact generated when assembling the refrigerator, transferring the refrigerator, using the refrigerator, or the like.

Further, in order to further secure the strength or reduce the plate thickness, the glass plate 7 may be subjected to a heat strengthening treatment, a chemical strengthening treatment, or the like. The glass plate 7 is an insulator.

Further, the refrigerating room door 2a and the refrigerating room door 2b are rotatably supported by upper hinges or the like (not shown) provided on the upper part of the refrigerator body 1, respectively. That is, it constitutes a so-called French door that is configured as a double door.

FIG. 2 is an explanatory view of a substrate to be arranged on the door of FIG. 1 and an arrangement portion thereof. 3A and 3B are perspective views of the substrate assembly, FIG. 4A is a perspective view of the substrate support, and FIG. 4B is a front view of the substrate.

As shown in FIG. 2, the door frame 12 connecting the door back member 10 and the door front member 7 of the refrigerator compartment door 2b is formed with a guide inlet 51 into which the substrate assembly 21 is inserted. In FIG. 2, the guide inlet 51 is formed in the frame 12 on the side opposite to the side pivotally supported by the hinge. As a result, when the refrigerating chamber doors 2a and 2b are closed, the position of the guide entrance 51 is not visible from the outside, so that the design is improved.

As shown in FIG. 3, the substrate assembly 21 is assembled by arranging the substrate 23 on the back surface side of the substrate support 24. The substrate 23 shown in FIG. 4B is provided with a light source (not shown) so that the user can see it from the outside through the film 22 and the glass plate 7 described later.

Further, as shown in FIGS. 7 and 9, in the lower part of the door frame 12, an insertion portion 41 for inserting the substrate assembly 21 and a recess 41d formed on the front side of the insertion portion 41 are provided. Have. The door frame 12 and the insertion portion 41 are molded as an integral part. Then, the substrate assembly 21 is inserted between the heat insulating material 9 and the glass plate 7 from the guide inlet 51 provided in the door frame 12, and the guide inlet 51 is closed by the lid 31. The film 22 is attached to the recess 41d. The glass plate 7 and the film 22 are provided with translucent portions around the light source, and these translucent portions are arranged on the front projection of the light source. In the present embodiment, the glass plate 7 is provided with a square hole-shaped translucent portion, and the film 22 is provided with a character-shaped translucent portion. As a result, the user can visually recognize that the characters and symbols are lit.

Next, the vertical positioning of the substrate support 24 (board assembly 21) with respect to the door frame 12 will be described.

First, as shown in FIG. 4A, the substrate support 24 is formed with a plurality of openings corresponding to the plurality of light sources on the substrate 23. Then, on the front side of the substrate support 24, a positioning convex portion 24a (first positioning portion) is formed at at least one of the edges between the openings.

On the other hand, the insertion portion 41 of the door frame 12 is also formed with a plurality of window portions corresponding to the plurality of openings of the substrate support 24. A positioning recess 41c (second positioning portion) is formed on the back surface side of the edge portion between the window portions, and by engaging with the positioning convex portion 24a of the substrate support 24, the positioning concave portion 41c (second positioning portion) is formed in the vertical direction. Is being positioned. The positioning recess 41c extends toward the back surface as a whole, and also plays a role of preventing light from leaking from each opening of the substrate support 24.

Next, the positioning of the substrate support 24 with respect to the door frame 12 in the left-right direction will be described.
When the substrate assembly 21 is pushed into the insertion portion 41, the convex portion 24c of the substrate assembly 21 abuts against the inner wall surface 41h of the insertion portion 41, so that the insertion of the substrate assembly 21 is locked. When the substrate assembly 21 is inserted until it is locked, the convex portion 24d and the convex portion 24e of the substrate assembly 21 engage with the notch 41f and the hole 41g of the insertion portion 41, respectively. As a result, the board assembly 21 once inserted is prevented from being displaced in the take-out direction.

Further, the positioning of the substrate support 24 with respect to the door frame 12 in the front-rear direction will be described. A positioning member 24b is provided at the end of the substrate support 24 on the side closer to the lid 31. Therefore, as the substrate assembly 21 is pushed into the insertion portion 41, the substrate assembly 21 is pushed toward the glass plate 7, that is, the front side. That is, the positioning member 24b positions the substrate support 24 in the front-rear direction with respect to the door frame 12. Further, the substrate support 24 is inserted into the insertion portion 41, and the positioning member 24b is finally pressed toward the front surface side, so that the positioning convex portion 24a engages with the positioning recess 41c.

By attaching the lid 31 after incorporating the substrate assembly 21 into the insertion portion 41, the positions of the substrate assembly 21 in the vertical direction, the horizontal direction, and the front-rear direction are further restricted.

Further, the positioning of the door frame 12 with respect to the glass plate 7 will be described. As shown in FIG. 7, the door frame 12 is provided with a glass ground plane 12c that regulates the position of the glass plate 7 in the front-rear direction. Further, the glass door frame 12 is provided with a convex portion 12b to regulate the position of the glass plate 7, and the convex portion 12b regulates the position of the glass plate 7 in the vertical and horizontal directions at the lower right of the refrigerator compartment door 2a. It is formed in an L shape. As a result, while aligning the end surface of the glass plate 7 with the convex portion 12b, the glass plate 7 is attached to the glass ground surface 12c using double-sided tape or the like, so that the positions of the glass plate 7 and the door frame 12 are vertically and horizontally aligned. It can be regulated in the direction and the front-back direction. Since the glass ground surface 12c is provided with the convex portion 12d, even when the glass plate 7 is attached by using an adhesive instead of the double-sided tape, the positions of the door frame 12 and the glass plate 7 in the front-rear direction are Be regulated.

Further, as shown in FIG. 9, a recess 41d for attaching the film 22 is formed on the surface of the insertion portion 41 on the glass plate 7 side (front side), and the wall surface around the recess 41d and the film 22 are formed. The positional relationship between the insertion portion 41 and the film 22 is determined by the side surface around the film 22. Further, the concave portion 41d is provided with a cylindrical convex portion 41e, and the film 22 is provided with a punched hole into which the cylindrical convex portion 41e is inserted. With such a cylindrical convex portion 41e and a punched hole, in addition to positioning the film 22, erroneous assembly of the front and back of the film 22 can be prevented.

In this way, by determining the positions of the substrate assembly 21 and the door frame 12 and the positions of the glass plate 7 and the door frame 12 in the front-rear direction, the left-right direction, and the vertical direction, the vertical direction and the vertical direction of each light source with respect to the glass plate 7 are determined. It is possible to prevent the relative position from shifting in the left-right direction. Therefore, even if the translucent portion formed on the glass plate 7 or the film 22 is not enlarged, the light source portion does not protrude to the outside of the transmissive portion, and the character light should appear lacking or not shining. It is possible to prevent the light from seeping out. Therefore, it is not necessary to position the characters apart from each other, and the design of the display unit is not restricted.

In addition, refrigerators may be vibrated by external force during the manufacturing, shipping, sales, and installation processes. At that time, if the film 22 provided with the character-shaped translucent portion is separated from the glass plate 7, the character light may be diffused by painting the glass plate 7 and appear blurred. However, in the present embodiment, as shown in FIG. 5, since the reinforcing portion 41a is provided on the back surface side of the insertion portion 41, warpage and foam deformation of the insertion portion 41 in the direction away from the glass plate 7 are suppressed. The film 22 is not separated from the glass plate 7 by a predetermined distance or more. Further, a tape pasting allowance 41b is provided on the front surface side of the insertion portion 41 to attach the tape, whereby the glass plate 7 and the insertion portion 41 are brought into close contact with each other. This tape also plays a role of preventing the foamed heat insulating material 9 from invading between the glass plate 7 and the insertion portion 41.

Next, wiring for connecting the board 23 to the control board on the top surface of the refrigerator body will be described. As shown in FIG. 8, a hole 41f for passing a cord for connecting to the substrate 23 is provided at the upper end of the insertion portion 41. The hole 41f is located higher than the horizontal projection of the substrate assembly 21 in the insertion direction. Further, a sealing material for preventing the foamed heat insulating material 9 from entering the insertion portion 41 from the hole 41f is attached to the cord. Therefore, when the substrate assembly 21 is inserted into the insertion portion 41 after the cord is inserted into the hole 41f, the sealing material and the cord are arranged at a position higher than that of the substrate assembly 21. As a result, it is possible to prevent the sealing material from being sandwiched between the substrate assembly 21 and the insertion portion 41 and the substrate assembly 21 being half-inserted.

Hereinafter, the heat insulating performance of the refrigerator compartment door 2b of the present embodiment will be described. As shown in FIG. 5, since the vicinity of both left and right ends inside the refrigerating chamber door 2b has protrusions 9a on the refrigerating chamber 2 side, between the door front plate 7 and the door back member 10 in this portion. The thickness dimension of the foamed heat insulating material 9 is larger than that of the other portion 9b. However, a plurality of door pockets are provided side by side on the inside of the refrigerator compartment door 2b, and a dent is formed on the front projection of the door pocket of the other portion 9b in order to store the door pockets. , The heat insulation performance of this part becomes low.

Here, in the portion of the refrigerator compartment door 2b where the insertion portion 41 is provided, the heat insulating material 9 is reduced by the amount of the space, so that the heat insulating performance is deteriorated. Therefore, it is desirable to avoid the recessed height of the other portion 9b described above as the position where the insertion portion 41 is provided. As a result, even if the inside of the insertion portion 41 is cooled by the influence of the cold air in the refrigerating chamber 2, the thickness of the heat insulating material 9 in that portion is maintained, so that the amount of heat leakage can be reduced, so that the front surface of the glass plate can be reduced. The occurrence of dew condensation can also be suppressed.

Further, as shown in FIG. 7, an upper portion of the door frame 12 is provided with a partition body fixing portion 12a for supporting a cord from the rotating partition body when the heat insulating material of the refrigerator compartment door 2b is foamed. The rotary partition is provided on the refrigerating room door 2b and closes the gap between the refrigerating room door 2a and the refrigerating room door 2b. A heater or the like is arranged inside the rotary partition body, and a cord is attached to connect the heater or the like to the control board.

The present embodiment is also characterized in that the above-mentioned substrate insertion portion 41 and the partition body fixing portion 12a are arranged above and below the same right side (rotary partition body side) in the same refrigerating chamber door 2b. .. With such an arrangement, the vacuum heat insulating material can be provided as wide as possible in the refrigerator compartment door 2b. If the partition body fixing portion 12a is provided on the upper right side of the door frame 12 and the insertion portion 41 is provided on the lower left side of the door frame 12, the vacuum heat insulating material must be arranged avoiding the partition body fixing portion 12a on the right side. On the other hand, the vacuum heat insulating material must be arranged on the left side as well, avoiding the insertion portion 41, and as a result, the expansion of the vacuum heat insulating material is restricted.

In the present embodiment, the board assembly 21 on which the light source is mounted is arranged in the insertion portion 41, but the wireless communication device may be mounted on the board assembly 21.
