Embodiments of the present invention will be described below with reference to the drawings, taking the first embodiment and the second embodiment as examples.
1. First embodiment
[Overall configuration of refrigerator]
First, the first embodiment will be described. FIG. 1 is a perspective view showing a refrigerator 1 of the present embodiment. In this application, the front-rear and top-bottom and left-right directions of the refrigerator 1 and its constituent members (frame members and panel members described later) are as shown by arrows in FIG. 1 unless otherwise specified. FIG. 2 is a front view of the refrigerator 1 with the door closed.

  The refrigerator 1 includes double doors on the upper and lower sides in front of the heat insulating box 2. That is, on the front side of the heat insulating box 2, an upper left door 3a, an upper right door 3b, a lower left door 3c, and a lower right door 3d are respectively attached. As described above, the refrigerator 1 is provided with the upper doors (3a, 3b) and the lower doors (3c, 3d) on the front side in the form of being arranged in the vertical direction. In addition, the display part 4 (for example, liquid crystal display panel) which displays the state etc. of the refrigerator 1 is provided in the door 3a.

  All of these doors (3a to 3d) (hereinafter sometimes collectively referred to as door 3) are separately manufactured as heat-insulating doors with heat-insulating specifications and attached to the heat-insulating box 2. A more detailed configuration and manufacturing method of the door 3 will be described again.

  The upper doors (3a, 3b) open and close the front of the refrigerator compartment 5 (see FIG. 3) described later, and the lower doors (3c, 3d) open and close the front of the freezer compartment 6 (see FIG. 3) described later. . FIG. 3 is a front view showing the refrigerator 1 when the door 3 is opened (however, the display of the lower doors (3c, 3d) is omitted).

  A refrigerator compartment 5 is provided in the upper part of the heat insulation box 2, and a freezer compartment 6 is provided in the lower part of the heat insulation box 2 through the heat insulation wall 7 with respect to the refrigerator compartment 5. In the refrigerator compartment 5, stored items are stored refrigerated, and in the freezer compartment 6, stored items are stored frozen. Hereinafter, the refrigerator compartment 5 and the freezer compartment 6 will be described.

  The rear wall 5a of the refrigerator compartment 5 is provided with a metal cooling panel 8 extending in the vertical direction at the center thereof. The cooling panel 8 forms a cold air passage (duct) (not shown) through which cold air flows together with the back wall 5a. The cold air flows from the lower side to the upper side of the cold air passage, and is discharged into the refrigerator compartment 5 from the discharge port provided in the upper portion of the cold air passage. The cool air discharged from the discharge port flows along the back wall 5a of the refrigerator, changes direction at the left and right ends, and flows forward along the side walls 5b and 5c of the refrigerator compartment 5.

  The cold air flowing along the side walls 5b and 5c of the refrigerator compartment 5 has a reduced flow velocity, reaches the center from the front of the refrigerator compartment, and cools the stored items. Thereby, the cool air which hits a store thing directly can be reduced and drying of a store thing can be controlled. Moreover, the temperature of a lower part can be made higher than the temperature of an upper part in the refrigerator compartment 5, and a store thing can be preserve | saved in a suitable position according to the appropriate preservation temperature of a store thing.

  Moreover, the cooling panel 8 cools the stored matter stored in the refrigerator compartment 5 together with the cold air discharged from the discharge port of the cold air passage by being cooled by the cold air flowing through the cold air passage. Therefore, the cooling effect is increased and power consumption necessary for cooling can be suppressed, and energy saving can be achieved.

  A tank room 13, a vegetable room 14, a fruit case 15, and a chilled room (fresh case) 16 are provided in the lower part of the refrigerator room 5. The tank chamber 13 stores a water tank for ice making. The vegetable compartment 14 is isolated with respect to the upper part of the refrigerator compartment 5, and a vegetable is accommodated. The fruit case 15 is isolated with respect to the upper part of the refrigerator compartment 5, and a fruit is accommodated.

  Since the vegetable compartment 14 and the fruit case 15 are cooled by the cold air discharged from the upper part of the refrigerator compartment 5 and circulated downward, the vegetable compartment 14 and the fruit case 15 are maintained at a temperature suitable for storing vegetables and fruits that are hotter than the surroundings. The chilled chamber 16 is isolated from the upper portion of the refrigerated chamber 5 and is maintained at a lower temperature than the surroundings because cold air is discharged from the lower portion of the cold air passage.

  A storage case 21 is slidably disposed in the vegetable compartment 14. In addition, a lid 22 that opens and closes between the front wall of the storage case 21 and the partition plate 9 that forms the upper wall of the vegetable compartment 14 is pivotally supported at the upper end of the vegetable compartment 14. The storage case 21 is provided with an upper surface open, and the back thereof is covered by the upper wall of the vegetable compartment 14.

  On the other hand, the front of the upper opening of the storage case 21 is covered with the lid portion 22 in a state where the storage case 21 is inserted into the vegetable compartment 14. In other words, the lid portion 22 is rotated according to the movement of the storage case 21 (slide), and opens and closes between the front wall of the storage case 21 and the upper wall of the vegetable compartment 14.

  The freezer compartment 6 is provided with an ice storage box 10 equipped with an automatic ice maker, three small freezing cases 11 and two large freezing cases 12. The ice storage box 10 stores ice made by an automatic ice maker (not shown) using the water in the tank chamber 13 (water tank). In the small refrigeration case 11 and the large refrigeration case 12, arbitrary stored items are stored frozen.

[Door structure]
Next, the configuration of the door 3 will be described in more detail. First, the lower door (3c, 3d) will be described. In the following description, the configuration of the lower left door 3c will be described, but the same applies to the lower right door 3d.

  FIG. 4 is a configuration diagram of the door 3c from the front viewpoint. 4 is a cross-sectional view in the vicinity of the upper end when the cross-section indicated by the alternate long and short dash line is viewed from the viewpoint indicated by A in the drawing. As shown in the figure, the door 3c is formed using a panel member 31, a frame member 32, and the like.

  The panel member 31 is formed in a flat plate shape having a rectangular periphery, and is provided in a shape supported by the frame member 32 so that the front surface faces forward. That is, the shape of the panel member 31 is a rectangle having each of the upper, lower, left and right sides when viewed from the front. The panel member 31 has a configuration in which printing is performed with a design on the back surface of a transparent glass plate (glass panel), and a scattering prevention film is attached on the printing.

  Thereby, the design is given to the panel member 31 on the rear side of the transparent glass plate, and this design is in a form that can be seen through the glass plate. In addition, the panel member 31 may have a configuration in which, for example, a predetermined sheet (a design printed on the front side) is attached to the back surface of the glass plate. Moreover, the front side of the door 3c has a form in which the front surface (glass plate) of the panel member 31 is exposed. As a result, the door 3c has an excellent design and the like.

  The frame member 32 is formed by molding of ABS resin or the like, and plays a role as an outer frame that supports the fitted panel member 31. The frame member 32 has a front surface portion 32a, a frame portion 32b, a side wall portion 32c, and the like. The front surface portion 32a is a portion that forms an appearance portion when viewed from the front, and has a rectangular outer edge when viewed from the front.

  The frame portion 32b is a portion provided so as to protrude forward from the front side of the front surface portion 32a so as to form a frame opened forward. More specifically, the frame portion 32b includes an upper frame portion 32b1, a lower frame portion 32b2, a left frame portion 32b3, and a right frame portion 32b4 corresponding to the upper, lower, left and right sides of the panel member 31.

  The upper frame portion 32b1 extends to the left and right at a position near the upper side of the front surface portion 32a, and the lower frame portion 32b2 extends to the left and right at the lower side of the front surface portion 32a. The left frame portion 32b3 extends vertically at a position near the left side of the front surface portion 32a, and the right frame portion 32b4 extends vertically near the right side of the front surface portion 32a.

  The frame portion 32b is adapted to the size of the peripheral edge of the panel member 31 so that the panel member 31 can be fitted from the front (the size of the opening is equal to or slightly larger than the peripheral edge of the panel member 31). Formed). The panel member 31 is fixed by being fitted into the frame portion 32b so that the front surface faces forward. The inner peripheral surface of the frame portion 32 b is configured to surround the peripheral edge of the panel member 31.

  In addition, in the part surrounded by the frame part 32b of the front part 32a, the part near the center is an opening part penetrating in the front-rear direction. As for the rear surface of the panel member 31, the vicinity of the outer edge is opposed to the front surface portion 32a surrounded by the frame portion 32b, and the inner portion thereof is in contact with the rear space through the opening.

  The side wall part 32c is a part that protrudes rearward from the vicinity of the upper, lower, left, and right sides of the front surface part 32a, and forms the side wall of the door 3c. The side wall portion 32c is configured to surround the space in contact with the rear surface of the panel member 31 from the top, bottom, left, and right directions.

  In addition, a door liner (not shown) is provided on the rear side of the side wall portion 32c to form an exterior portion of the door 3c as viewed from the rear. The door liner constitutes a part of the inner wall of the refrigerator 1, and together with the panel member 31 and the frame member 32, a space in contact with the rear surface of the panel member 31 is a closed space. The space is filled with foamed urethane (not shown). The urethane foam serves as a heat insulating material and also serves as an adhesive that bonds the panel member 31 and the frame member 32 together.

  Moreover, in this embodiment, the form which exposed the whole front surface of the panel member 31 ahead so that the frame member 32 may not be hung on the front surface of the panel member 31 is employ | adopted. As a result, the door 3c has a more excellent design and the like.

  FIG. 5 is a detailed view of a portion B shown in FIG. As shown in the figure, the panel member 31 has a side portion 31a facing the inner surface of the frame portion 32b. Here, the entire frame part 32b (entire circumference) is formed so as not to be hung on the front outer edge of the panel member 31 (a wrinkleless frame part, a second frame part). That is, when the virtual plane P1 is set so as to be in contact with the side portion 31a and expand in the front-rear direction, the entire frame portion 32b has a portion like a ridge protruding inward (downward in FIG. 5) from the virtual plane P1. It has a shape that does not. Therefore, the front surface 31b of the panel member 31 has a form in which the entire outer edge is exposed forward (rightward in FIG. 5).

  The upper frame portion 32b1 has a shape protruding forward from the virtual plane P2 set to include the front surface 31b of the panel member 31. More specifically, the front end of the upper frame portion 32b1 (the portion indicated by the white arrow in FIG. 5) is positioned forward from the virtual plane P2 by the protruding length h.

  As described above, the upper frame portion 32b1 protrudes forward from the virtual plane P2, and thus the door 3c has enhanced protection of the peripheral portion of the panel member 31. For example, when the refrigerator 1 is used or transported, a situation is assumed in which objects collide from the diagonally forward direction toward the peripheral edge of the panel member 31. In this case, if the upper frame portion 32b1 does not protrude forward from the virtual plane P2, an object directly hits the peripheral edge of the panel member 31 near the upper frame portion 32b1, and the panel member 31 is easily broken. In addition, when the forward projection of the frame portion 32b is small, the panel member 31 tends to be weak against impact.

  In this case, in the case of the present embodiment, even when an object collides from the diagonally forward toward the peripheral edge of the panel member 31, the upper frame portion 32b1 serves as a guard, and the object directly hits the peripheral edge of the panel member 31. Is avoided as much as possible, so that the panel member 31 is relatively difficult to break. Further, the panel member 31 is more resistant to impact than the case where the upper frame portion 32b1 does not protrude forward from the virtual plane P2. Moreover, even if the end surface treatment of the panel member 31 is insufficient, the upper frame portion 32b1 is projected forward from the virtual plane P2, thereby preventing the injury caused by the user's hand touching the end surface as much as possible. It is.

  Here, considering that the refrigerator 1 is a specification in which the upper doors (3a, 3b) and the lower doors (3c, 3d) are arranged in the vertical direction, the lower side of the lower door (in many cases, Compared to the upper side of the upper door (often located near the user's head) and the upper side of the upper door and the lower side of the upper door. It is thought that it is easy to hit.

  Therefore, regarding the door 3c (the door 3d is the same) as the lower door, the lower frame portion 32b2, the left frame portion 32b3, and the right frame portion 32b4 are not projected forward from the virtual plane P2 with an emphasis on design. On the other hand, with emphasis on protection of the panel member 31, the upper frame portion 32b1 is projected forward from the virtual plane P2. As a result, the door 3c achieves both safety and design as much as possible. However, the form of the frame portion 32b is not limited to this, and for example, the entire frame portion 32b may protrude forward from the virtual plane P2.

  The protruding length h of the upper frame portion 32b1 is preferably set to an appropriate value with no excess or deficiency in consideration of safety, design and the like. For example, the protrusion length h is set to 1 mm.

  Further, the front end of the upper frame portion 32b1 has a round shape (roundness) as shown in FIG. Therefore, the door 3c is designed so that the protrusion of the upper frame portion 32b1 is not emphasized and the design is improved. In addition, since the round shape is adopted, even when the hand of the user touches, no injury is caused.

  As a modification, the front end of the upper frame portion 32b1 may be further tapered as shown in FIG. In this way, it is possible to prevent the protrusion of the upper frame portion 32b1 from being emphasized more and improve the design.

  FIG. 7 is a detailed view of the portion C shown in FIG. 4 and shows one form near the intersection of the upper frame portion 32b1 and the left frame portion 32b3. As shown in FIG. 7, the upper frame portion 32b1 and the left frame portion 32b3 are connected, but the length of the forward protrusion is changed near the boundary between the both. That is, the portion of the upper frame portion 32b1 (hatched portion in the figure) protrudes forward from the virtual plane P2, and the portion of the left frame portion 32b3 (portion without hatching) does not protrude forward from the virtual plane P2. Various forms such as a form in which the frame parts are not connected to each other and a form in which the length of the protrusion changes smoothly can be adopted as the form in the vicinity of the intersection between the frame parts (32b1 to 32b4).

  Next, the configuration of the upper door (3a, 3b) will be described. In the following description, the configuration of the upper left door 3a will be described, but the same applies to the upper right door 3b. Further, the description of the configuration different from that of the lower door (3c, 3d) already described is emphasized, and description of the common configuration may be omitted.

  FIG. 8 is a configuration diagram of the door 3a from the front viewpoint, which is displayed through the frame member 32 and the like. A display substrate support portion 32d is provided on the frame member 32 constituting the door 3a. The display substrate support part 32d is a part for supporting the display substrate 41 on which the display unit 4 described above is mounted. The display substrate 41 is supported at the position shown in FIG. 8 by the display substrate support portion 32d so that the display unit 4 faces forward. A user in front of the door 3a can see the display on the display unit 4.

  For the door 3a which is the upper door (the same applies to the door 3b), the upper frame portion 32b1, the left frame portion 32b3, and the right frame portion 32b4 are included so as to include the front surface of the panel member 31 with emphasis on design. While making it not project forward from the set virtual plane P2, the lower frame portion 32b2 is projected forward from the virtual plane P2 with emphasis on protection of the panel member 31.

  As a result, the door 3a achieves both safety and design as much as possible. However, the form of the frame portion 32b is not limited to this, and for example, the entire frame portion 32b may protrude forward from the virtual plane P2.

[Manufacturing method of door]
Next, a method for manufacturing the door 3 will be described. In addition, in the following description, although the manufacturing method of the upper left door 3a is demonstrated for convenience, it is basically the same also about other doors (3b-3d).

  The step of manufacturing the door 3a includes a step of positioning the panel member 31 by fitting it into the frame portion 32b of the frame member 32 (positioning step).

  In the positioning step, the panel member 31 and the frame member 32 are used, and the panel member 31 is fitted into the frame portion 32b. At this time, a double-sided tape is interposed between the front surface portion 32 a of the frame member 32 and the rear surface of the panel member 31, and bonding (primary bonding) is performed between the panel member 31 and the frame member 32. Keep it like that. That is, the rear surface of the panel member 31 fitted into the frame portion 32b is fixed to the frame member 32 by using a double-sided tape.

  By the primary bonding, the panel member 31 is fixed with a certain amount of adhesive force and is appropriately positioned inside the frame portion 32b. Further, the primary bonding also plays an auxiliary role in bonding (secondary bonding) using foamed urethane, which will be described later, and makes the panel member 31 more firmly fixed.

  Here, the state of the positioning process of this embodiment is illustrated in FIG. As shown in the figure, in the positioning step, the frame member 32 is set on a predetermined jig 50a, and the panel member 31 is set on a predetermined jig 50b. The cross sections of the panel member 31 and the frame member 32 shown in FIG. 9 correspond to the cross section indicated by the two-dot chain line in FIG. A double-sided tape 35 is attached to the front surface portion 32a of the frame member 32 in advance over the entire inner periphery of the frame portion 32b.

  Then, by bringing the jig 50a closer to the jig 50b, the frame member 32 is moved in the direction indicated by the white arrow until the rear surface of the panel member 31 comes into close contact with the front surface portion 32a of the frame member 32. The positioning of the panel member 31 is achieved by the positioning process so far. An embodiment in which the positioning process is performed more easily will be described again as the second embodiment.

  Moreover, the process of manufacturing the door 3a includes a process (adhesion process) of bonding and fixing the panel member 31 positioned in the positioning process to the frame member 32 using urethane foam.

  In the bonding process, by filling the space inside the frame member 32 in which the panel member 31 is positioned (the space surrounded by the panel member 31, the frame member 32, and the door liner) with urethane foam, The frame member 32 is firmly bonded (secondary bonding). The door 3a is completed through the above-described positioning process, bonding process, and other processes.

2. Second Embodiment Next, a second embodiment will be described. The second embodiment is basically the same as the first embodiment except that a part of the frame portion 32b is a frame portion with a ridge so that the positioning process can be performed more easily. In the following description, emphasis is placed on the description of parts different from the first embodiment, and description of common parts may be omitted.

  In the frame member 32 of the second embodiment, the left frame portion 32b3 of the frame portion 32b is formed so as to be hooked on the outer edge of the front surface of the panel member 31 (a frame portion with a flange, a first frame portion). The other upper frame portion 32b1, lower frame portion 32b2, and right frame portion 32b4 are wrinkleless frame portions.

  FIGS. 10 and 11 show the positioning process according to the second embodiment. The cross sections of the panel member 31 and the frame member 32 shown in these drawings correspond to the cross section indicated by the two-dot chain line in FIG. In addition, on the lower side of these drawings, an enlarged view of a portion surrounded by a solid line is shown.

  In the positioning step, the panel member 31 and the frame member 32 in which the double-sided tape 35 is attached in advance to a portion inside the frame portion 32b of the front surface portion 32a are prepared. In addition, attachment of the double-sided tape 35 is abbreviate | omitted in the side (left side) in which the frame part with a ridge is provided among the parts inside the frame part 32b of the front part 32a.

Then, as shown in FIG. 10, first, the left side (one side) of the panel member 31 is held in the left frame portion 32b3 (the frame portion with the flange), and the panel member 31 is rotated a little around this left side as an axis. The right side of the member 31 is fitted into the frame portion 32b. Then, as shown in FIG. 11, a paper tape 39 is attached so as to close the gap between the left side of the front surface portion 32 a and the panel member 31. The positioning of the panel member 31 is achieved by the positioning process so far.

  According to the positioning process of the second embodiment, the panel member 31 can be easily positioned as compared with the positioning process of the first embodiment. That is, in the case of the first embodiment, the positioning jig becomes very large like the jigs (50a, 50b) illustrated in FIG. 9, and if the jig is not used, positioning is very It becomes difficult. In this regard, in the case of the second embodiment, after holding one side of the panel member 31 in the frame portion with the ridge, it is only necessary to slightly rotate the panel member 31 while the frame portion with the heel supports the one side. Therefore, the panel member 31 can be easily positioned.

  In the case of the second embodiment, since the panel member 31 is positioned by using the frame portion with the heel, the double-sided tape 35 is provided on the side (left side) where the heel frame portion is provided as described above. Can be omitted. Therefore, the amount of double-sided tape used can be reduced, and the manufacturing cost can be reduced.

  In the second embodiment, the left frame portion 32b3 is a frame portion with a heel, but instead, the upper frame portion 32b1, the lower frame portion 32b2, or the right frame portion 32b4 may be a rimmed frame portion. The panel member 31 can be positioned by a method according to the positioning step. However, when using a vertically long panel member 31 (longer in the vertical direction than the left-right direction) as in the present embodiment, the left frame portion 32b3 (or the right frame portion 32b4) is considered in consideration of ease of rotation of the panel member 31 and the like. Is preferably a frame portion with a wrinkle.

3. Others As described above, the door 3 of the first embodiment and the second embodiment is a frame having a panel member 31 formed in a flat plate shape and a frame portion 32b that opens forward and surrounds the periphery of the panel member 31. And a member 32. The door of the refrigerator 1 is configured such that the panel member 31 is fitted into the frame portion 32b and positioned and fixed so that the front surface of the panel member 31 faces forward. Further, in the door 3, the whole or a part of the frame part 32 b is a wrinkleless frame part formed so as not to hang on the front outer edge of the panel member 31, and the whole or part of the wrinkleless frame part is a panel member 31. It protrudes forward from the virtual plane P2 set to include the front surface.

  Therefore, the door 3 can reinforce the protection of the peripheral edge of the panel member 31 while preventing the frame member 32 from hanging over the whole or part of the front outer edge of the panel member 31. More specifically, the shape of the panel member 31 is a rectangle having upper, lower, left and right sides when viewed from the front, and the frame portion 32b corresponds to the upper, lower, left and right sides of the panel member 31. It consists of a part 32b1, a lower frame part 32b2, a left frame part 32b3, and a right frame part 32b4.

<Appendix>
In order to achieve the above object, a door according to another aspect of the present invention includes a panel member formed in a substantially flat plate shape, and a frame member having a frame portion that opens forward and surrounds the periphery of the panel member. The panel member is a refrigerator door in which the panel member is fitted and positioned and fixed, and the front surface of the panel member faces forward. The whole or a part of the frame portion is the panel member. A wrinkleless frame portion formed so as not to hang on the front outer edge of the front panel, and the whole or part of the wrinkleless frame portion is protruded forward from a virtual plane set so as to include the front surface of the panel member. The configuration.
