Description

  The present invention relates to a refrigerator having an outer plate on the surface of a door.

  As a display unit for displaying settings and the like, there has been proposed a refrigerator in which a substrate support is inserted through an opening on a side surface or a bottom surface of a door so that it can be recognized through a glass plate constituting the surface of the door. For example, Patent Document 1 states that “the substrate support 31 is formed by integrally forming the substrate mounting portions 38 and 39 and the cover plate portion 40 as shown in FIGS. The substrate mounting portions 38 and 39 face the operation and display illustration 32a provided at the lower end portion of the glass plate 25, and the lid plate portion 40 closes the opening of the substrate support plate insertion recess 37 ". (Paragraph 0038). Further, the document discloses that the substrate support 31 is integrally formed with positioning portions 43 for positioning in the front-rear direction at the upper end portion of one substrate mounting portion 39 and the left and right end portions of the cover plate portion 40, respectively. The position in the front-rear direction is regulated by fitting into recesses (not shown) provided in the substrate support insertion recess 37 "(paragraph 0040).

Japanese Patent Laying-Open No. 2015-48985

  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 position of each light source installed on the substrate support with respect to the glass plate is determined by the substrate support and the glass. It may change as the plate moves in the left-right direction. If the light source part is displaced outside the light-transmitting part of the glass, the display may appear to be missing or light may be blurred in the display that should not have been lit. In order to prevent this, it is necessary to set the glass translucent part larger than the light source in consideration of positional deviation. For this reason, in the above-mentioned Patent Document 1, each display illustration provided on the glass plate corresponding to each light source needs to be set apart from each other because it is necessary to set the translucent part larger. There was a problem that the design of the display unit was restricted.

  Then, the objective of this invention is providing the refrigerator which improved the designability of the display part in a glass-made outer plate.

  The present invention is filled in a space formed by a glass outer plate provided on the front side of the heat insulating door, a door frame provided on a peripheral edge of the outer plate, and the outer plate and the door frame. In a refrigerator comprising a foam insulation and a substrate support provided with a light source on the back side of the outer plate, the door frame is formed with an insertion portion into which the substrate support is inserted, A coating surface having a translucent part is formed on the back side of the outer plate, the light source is located in a rear side projection of the translucent part, and the outer plate has the substrate support on the insertion part. In the inserted state, the substrate support was positioned in the front-rear direction, the up-down direction, and the left-right direction with respect to the door frame.

  In the refrigerator of the present embodiment, a light-transmissive 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 to be described later is arranged on the back side of the refrigerator compartment door 2b to constitute a display unit 50. Further, as shown in FIG. 5, the foamed heat insulating material (heat insulating material) 9 is filled and foamed between a door front plate (door front member) 7 and a door rear member 10, taking 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 this embodiment. This plate | board thickness is a dimension which the glass plate 7 does not break by the impact which arises at the time of refrigerator assembly, refrigerator transport, a refrigerator use, etc., or a crack does not arise.

  Further, when further strengthening the strength or reducing 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.

  Moreover, the refrigerator compartment door 2a and the refrigerator compartment door 2b are each rotatably supported by the upper hinge etc. (not shown) provided in the upper part of the refrigerator main body 1, respectively. That is, what is called a French door comprised by the double-spread type is comprised.

  FIG. 2 is an explanatory diagram of a substrate and its arrangement portion arranged on the door of FIG. 3 is a perspective view 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, a guide inlet 51 into which the board assembly 21 is inserted is formed in the door frame 12 that connects the door rear member 10 and the door front member 7 of the refrigerator compartment door 2b. The guide inlet 51 is formed in the frame 12 on the side opposite to the side pivotally supported by the hinge in FIG. Thereby, when the refrigerator doors 2a and 2b are closed, the position of the guide inlet 51 is not visually recognized 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 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 visually recognize the film 22 and the glass plate 7 described later from the outside.

  Further, as shown in FIGS. 7 and 9, at the lower part of the door frame 12, an insertion part 41 for inserting the board assembly 21 and a recess 41d formed on the front side of the insertion part 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 affixed to the recess 41d. The glass plate 7 and the film 22 are provided with a light transmitting part around the light source, and these light transmitting parts 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-type translucent portion. Thereby, the user can visually recognize that characters and symbols are lit.

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

  First, the substrate support 24 is formed with a plurality of openings corresponding to the plurality of light sources on the substrate 23 as shown in FIG. And the positioning convex part 24a (1st positioning part) is formed in at least one place of the edge part between an opening part among the front sides of the board | substrate support body 24. As shown in FIG.

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

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

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

  In addition, the position of the board assembly 21 in the vertical direction, the left-right direction, and the front-back direction is further regulated by attaching the lid 31 after the board assembly 21 is assembled in the insertion portion 41.

  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 surface 12 c 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 for regulating 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. Thus, the glass plate 7 and the door frame 12 are positioned in the vertical direction, left and right by attaching the glass plate 7 to the glass ground surface 12c using a double-sided tape or the like while aligning the end surface of the glass plate 7 with the convex portion 12b. It can be regulated in the direction and front-rear direction. In addition, since the convex part 12d is provided in the glass grounding surface 12c, even when the glass plate 7 is pasted using an adhesive instead of the double-sided tape, the position of the door frame 12 and the glass plate 7 in the front-rear direction is Be regulated.

  Moreover, as shown in FIG. 9, the glass plate 7 side (front side) surface of the insertion portion 41 is formed with a recess 41d for attaching the film 22, 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 peripheral side surface. Further, the concave portion 41d is provided with a cylindrical convex portion 41e, and the film 22 is provided with a punch hole into which the cylindrical convex portion 41e is inserted. In addition to the positioning of the film 22, misalignment of the front and back of the film 22 can be prevented by such cylindrical convex portions 41e and the punched holes.

  Thus, 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, respectively, The shift of the relative position in the left-right direction can be prevented. For this reason, even if it does not enlarge the translucent part formed in the glass plate 7 or the film 22, the light source part does not protrude outside the translucent part, and the character light should be seen missing or not shining. It is possible to prevent light from oozing out. Therefore, it is not necessary to place the characters apart from each other, and the design of the display unit is not easily restricted.

  In addition, the refrigerator may be vibrated by an external force in the process of manufacture, shipment, sale, and installation. 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 the coating of the glass plate 7 and may appear blurred. However, in this embodiment, as shown in FIG. 5, since the reinforcing portion 41a is provided on the back side of the insertion portion 41, warpage and foam deformation in a direction in which the insertion portion 41 is separated from the glass plate 7 are suppressed, The film 22 is not separated from the glass plate 7 by a predetermined distance or more. Moreover, the tape pasting allowance 41b is provided in the front side of the insertion part 41, and the tape is affixed and the glass plate 7 and the insertion part 41 are stuck by this. This tape also serves to prevent the foam heat insulating material 9 from entering 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 main body will be described. As shown in FIG. 8, a hole 41 f 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 at a position higher than the horizontal projection in the insertion direction of the board assembly 21. Further, a sealing material for preventing the foam heat insulating material 9 from entering the insertion portion 41 from the hole 41f is attached to the cord. For this reason, when the board assembly 21 is inserted into the insertion portion 41 after the cord is inserted into the hole 41 f, the sealing material and the cord are disposed at a higher position than the board assembly 21. Thereby, the sealing material is sandwiched between the board assembly 21 and the insertion portion 41, and the board assembly 21 can be prevented from being half-inserted.

  Hereinafter, the heat insulation performance of the refrigerator compartment door 2b of this embodiment is demonstrated. As shown in FIG. 5, since the left and right both ends near the inside of the refrigerator compartment door 2b have protrusions 9a on the refrigerator compartment 2 side, the space between the door front plate 7 and the door rear member 10 in this portion. The thickness of the foam heat insulating material 9 is larger than that of the other portion 9b. However, inside the refrigerator compartment door 2b, a plurality of door pockets are provided vertically, and in order to store the door pockets, a recess is formed on the front projection of the door pocket of the other portion 9b. The heat insulation performance of this part is lowered.

  Here, about the part in which the insertion part 41 is provided among the refrigerator compartment doors 2b, since the heat insulating material 9 decreases by the part of the space, heat insulation performance will fall. Therefore, it is desirable to avoid the above-described height of the other portion 9b having a recess as a position where the insertion portion 41 is provided. Thereby, even if the inside of the insertion part 41 is cooled by the influence of the cold in the refrigerator compartment 2, since the thickness of the heat insulating material 9 of the part is maintained, since the amount of heat leakage can be reduced, the front surface of the glass plate It is also possible to suppress the occurrence of condensation on the surface.

  Moreover, as shown in FIG. 7, the partition frame fixing | fixed part 12a for supporting the code | cord | chord from a rotation partition is provided in the upper part of the door frame 12 at the time of foaming of the heat insulating material of the refrigerator compartment door 2b. In addition, a rotation partition is provided in the refrigerator compartment door 2b, and closes the clearance gap between the refrigerator compartment door 2a and the refrigerator compartment door 2b. A heater or the like is disposed inside the rotary partition, and a cord is attached to connect the heater and the control board.

  The present embodiment is also characterized in that the above-described substrate insertion portion 41 and the partition fixing portion 12a are arranged above and below the same right side (rotating partition side) in the same refrigerator compartment door 2b. . By adopting such an arrangement, it is possible to provide a wide range of vacuum heat insulating materials within the refrigerator compartment door 2b. If the partition fixing part 12a is provided in the upper right part of the door frame 12 and the insertion part 41 is provided in the lower left part of the door frame 12, the vacuum heat insulating material should not be arranged on the right side avoiding the partition fixing part 12a. On the other hand, the vacuum heat insulating material must be disposed on the left side while avoiding the insertion portion 41. As a result, the expansion of the vacuum heat insulating material is limited.

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