US Patent Application Publication No. 2011/0089790

  In the above-described door in which the front surface of the glass plate is largely exposed, protection of the peripheral portion (end surface) of the glass plate becomes a problem. For example, if an object is accidentally hit against the peripheral edge of the glass plate, the glass plate is cracked from that portion, and there is a concern that the user may be injured.

  Such inconvenience can be prevented to some extent by the frame surrounding the peripheral edge of the glass plate, but when the degree of protrusion of the frame forward is small, it cannot be said to be sufficient from the viewpoint of protection of the glass plate. For example, assuming that an object collides obliquely from the front toward the periphery of the glass plate, if the degree of protrusion of the frame is equal to or less than the front position of the glass plate, the periphery of the glass plate is appropriately protected. It is difficult. Note that the above-described problem may be applicable even when a panel member other than a glass plate (a substantially flat member supported by a frame member) is employed.

  The present invention has been made in view of the above-described problems, and provides a refrigerator door capable of strengthening protection of a peripheral portion of a panel member while preventing a frame member from covering the whole or a part of a front outer edge of the panel member. Aim. Another object of the present invention is to provide a refrigerator provided with the door.

  When viewed from the front, the refrigerator door according to the present invention has a substantially rectangular peripheral edge having upper, lower, left, and right sides, a panel member formed in a substantially flat plate shape, and a peripheral edge of the panel member that opens forward. And a frame member having a frame portion surrounding the panel member, wherein the front surface of the panel member is directed forward, and one side of the frame portion is set to include the front surface of the panel member. And projecting the other three sides of the frame portion forward from the virtual plane.

An embodiment of the present invention will be described below with reference to each drawing, taking a first embodiment and a second embodiment as examples.
1. First embodiment
[Overall configuration of refrigerator]
First, a first embodiment will be described. FIG. 1 is a perspective view showing a refrigerator 1 of the present embodiment. In the present application, the directions of the refrigerator 1 and its components (frame members, panel members, and the like, which will be described later) in the front-rear, up-down, and left-right directions are as indicated by arrows in FIG. 1 unless otherwise specified. FIG. 2 is a front view of the refrigerator 1 with the door closed.

  Refrigerator 1 is provided with double doors on the upper and lower sides in front of heat insulation box 2. That is, an upper left door 3a, an upper right door 3b, a lower left door 3c, and a lower right door 3d are attached to the front side of the heat insulating box 2, respectively. 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 a vertically arranged manner. Note that the door 3a is provided with a display unit 4 (for example, a liquid crystal display panel) for displaying the state of the refrigerator 1 and the like.

  These doors (3 a to 3 d) (hereinafter sometimes collectively referred to as doors 3) are all separately manufactured as heat-insulating doors of heat-insulating specification, and are attached to the heat-insulating box 2. Note that a more detailed configuration and a manufacturing method of the door 3 will be described again.

  The upper doors (3a, 3b) open and close the front of a refrigerator 5 (see FIG. 3) described later, and the lower doors (3c, 3d) open and close the front of a freezer 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 refrigerating room 5 is provided at an upper portion of the heat insulating box 2, and a freezing room 6 is provided at a lower portion of the heat insulating box 2 via a heat insulating wall 7 with respect to the refrigerating room 5. In the refrigerating compartment 5, the stored items are refrigerated and stored, and in the freezing compartment 6, the stored items are frozen and stored. Hereinafter, each of the refrigerator compartment 5 and the freezer compartment 6 will be described.

  A metal cooling panel 8 that extends in the vertical direction at the center of the back wall 5a of the refrigerator compartment 5 is provided. The cooling panel 8 forms a not-shown cool air passage (duct) through which cool air flows together with the back wall 5a. The cool air flows upward from below the cool air passage, and is discharged into the refrigerating chamber 5 laterally from a discharge port provided at an upper portion of the cool air passage. The cool air discharged from the discharge port flows along the back wall 5a of the refrigerator, changes direction at left and right ends, and flows forward along the side walls 5b and 5c of the refrigerator compartment 5.

  The flow rate of the cool air flowing along the side walls 5b and 5c of the refrigerator compartment 5 decreases, and reaches the center from the front part of the refrigerator compartment to cool the storage. Thereby, it is possible to reduce the cool air directly hitting the storage object and suppress the drying of the storage object. Further, the temperature of the lower part can be higher than the temperature of the upper part in the refrigerating compartment 5, and the stored item can be stored at an appropriate position according to the proper storage temperature of the stored item.

  The cooling panel 8 itself is cooled by the cool air flowing through the cool air passage, and thereby cools the stored matter stored in the refrigerator compartment 5 together with the cool air discharged from the discharge port of the cool air passage. Therefore, the cooling effect is increased, the power consumption required for cooling can be suppressed, and energy can be saved.

  A tank room 13, a vegetable room 14, a fruit case 15, and a chilled room (fresh case) 16 are provided below the refrigerator compartment 5. The tank chamber 13 houses a water tank for making ice. The vegetable compartment 14 is isolated from the upper part of the refrigerator compartment 5 and stores vegetables therein. The fruit case 15 is isolated from the upper part of the refrigerator compartment 5 to store fruits.

  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, so that the vegetable compartment 14 and the fruit case 15 are maintained at a temperature suitable for storing vegetables and fruits which are higher in temperature than the surroundings. The chilled chamber 16 is isolated from the upper part of the refrigerating chamber 5, and is maintained at a lower temperature than the surroundings because the cool air is discharged from the lower part of the cool air passage.

  A storage case 21 is slidably disposed in the vegetable compartment 14. At the upper end of the vegetable compartment 14, a lid 22 for opening and closing between the front wall of the storage case 21 and the partition plate 9 forming the upper wall of the vegetable compartment 14 is pivotally supported. The storage case 21 is provided with an open upper surface, and the rear is covered by the upper wall of the vegetable compartment 14.

  On the other hand, the front of the upper surface opening of the storage case 21 is covered by the lid 22 in a state where the storage case 21 is inserted into the vegetable compartment 14. That is, the lid 22 rotates in accordance with the movement (slide) of the storage case 21 and opens and closes the space 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 water in the tank chamber 13 (water tank). In the small freezing case 11 and the large freezing case 12, arbitrary stored items are stored frozen.

[Door configuration]
Next, the configuration of the door 3 will be described in more detail. First, the lower doors (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 as viewed from the front. In FIG. 4, a portion surrounded by a broken line is a cross-sectional view near the upper end when the cross-section indicated by a dashed line in the drawing is viewed from the viewpoint indicated by A. 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 peripheral edge, and is provided in a manner 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 upper, lower, left, and right sides when viewed from the front. In addition, the panel member 31 performs printing with a design applied to the back surface of a transparent glass plate (glass panel).
It has a configuration in which a film for preventing scattering is attached.

  As a result, the panel member 31 is designed such that the design is applied to the rear side of the transparent glass plate, and the design is visible 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. 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 specifications with excellent design and the like.

  The frame member 32 is formed by molding an ABS resin or the like, and functions 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 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 each of the upper, lower, left, and right sides of the panel member 31.

  The upper frame portion 32b1 extends left and right at a position closer to the upper side of the front surface portion 32a, and the lower frame portion 32b2 extends left and right at a lower position near the front surface portion 32a. The left frame portion 32b3 extends vertically at a position closer to the left side of the front surface portion 32a, and the right frame portion 32b4 extends vertically at a position closer to 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). Is formed). The panel member 31 is fitted and fixed in the frame portion 32b, and the front surface is directed forward. The inner peripheral surface of the frame portion 32b is configured to surround the peripheral edge of the panel member 31.

  In the portion surrounded by the frame portion 32b of the front portion 32a, the portion near the center is an opening penetrating in the front-rear direction. The rear surface of the panel member 31 has a portion near the outer edge facing the front portion 32a surrounded by the frame portion 32b, and a portion inside the front portion contacts the rear space via the opening.

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

  Further, a door liner (not shown) that forms an exterior portion of the door 3c as viewed from the rear is provided on the rear side of the side wall portion 32c. 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, defines a space in contact with the rear surface of the panel member 31 as a closed space. The space is filled with urethane foam (not shown). The urethane foam serves not only as a heat insulating material but also as an adhesive for bonding the panel member 31 and the frame member 32.

  Further, in the present embodiment, a mode is adopted in which the entire front surface of the panel member 31 is exposed forward so that the frame member 32 does not hang on the front surface of the panel member 31. As a result, the door 3c has specifications that are more excellent in design and the like.

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

  The upper frame portion 32b1 has a shape protruding forward from a 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 a white arrow in FIG. 5) is located forward of the virtual plane P2 by a protruding length h.

  By thus protruding the upper frame portion 32b1 forward from the virtual plane P2, 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, it is conceivable that an object collides from diagonally forward toward the periphery 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 portion of the panel member 31 near the upper frame portion 32b1, and the panel member 31 is easily broken. In addition, when the frame portion 32b is less protruded forward, the panel member 31 tends to be weaker against impact.

  In this regard, in the case of the present embodiment, even when an object collides obliquely from the front toward the peripheral portion of the panel member 31, the upper frame portion 32b1 acts as a guard and the object directly hits the peripheral portion of the panel member 31. Is avoided as much as possible, so that the panel member 31 is relatively hard to crack. The panel member 31 is more resistant to impact than when the upper frame portion 32b1 does not protrude forward from the virtual plane P2. Further, 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, so that injury due to the user's hand touching the end surface is minimized. It is.

  Here, considering that the refrigerator 1 has a specification in which the upper door (3a, 3b) and the lower door (3c, 3d) are vertically arranged, the lower side of the lower door (in many cases, The upper side of the lower door and the lower side of the upper side door are located in comparison with the upper side of the upper door (often located near the user's feet) and the upper side of the upper door (often near the user's head). Is likely to collide.

  Therefore, with respect to the lower door 3c (same for the door 3d), 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 emphasis on design. On the other hand, the protection of the panel member 31 is emphasized so that the upper frame portion 32b1 projects forward from the virtual plane P2. As a result, the door 3c balances 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.

  It is desirable that the protruding length h of the upper frame portion 32b1 be 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.

  As shown in FIG. 5, the front end of the upper frame portion 32b1 has a round shape (roundness). Therefore, the door 3c is designed so that the protrusion of the upper frame portion 32b1 is not emphasized and the design is enhanced. Further, the adoption of the round shape prevents the user from being injured when touched by the user's hand.

As a modification, the front end of the upper frame portion 32b1 may have a further tapered shape as shown in FIG. By doing so, it is possible to prevent the protrusion of the upper frame portion 32b1 from being emphasized more, and to further enhance 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 projection changes near the boundary between 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. In addition, as a form near the intersection of the frame parts (32b1 to 32b4), 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.

  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. In addition, emphasis is placed on the description of the configuration different from that of the lower doors (3c, 3d) already described, and the description of the common configuration may be omitted.

  FIG. 8 is a configuration diagram of the door 3a as viewed from the front side, and is shown through the frame member 32 and the like. The display substrate support part 32d is provided in the frame member 32 which comprises the door 3a. The display substrate support part 32d is a part for supporting the display substrate 41 on which the display part 4 described above is mounted. The display substrate 41 is supported at the position shown in FIG. 8 by the display substrate support 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 upper door 3a (same for the door 3b), the upper frame portion 32b1, the left frame portion 32b3, and the right frame portion 32b4 include the front surface of the panel member 31 with emphasis on design. The lower frame portion 32b2 is made to protrude forward from the virtual plane P2 while preventing the panel member 31 from protruding forward from the set virtual plane P2.

  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.

[Door manufacturing method]
Next, a method for manufacturing the door 3 will be described. In the following description, a method of manufacturing the upper left door 3a will be described for convenience, but the same applies to other doors (3b to 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 32a 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. So that That is, the rear surface of the panel member 31 fitted into the frame portion 32b is attached and fixed to the frame member 32 using a double-sided tape.

By the primary bonding, the panel member 31 is fixed with a certain adhesive force, and is appropriately positioned inside the frame portion 32b. In addition, the primary bonding also plays an auxiliary role of bonding (secondary bonding) using urethane foam, which will be described later, and makes the bonding and fixing of the panel member 31 stronger.

  Here, the state of the positioning step 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. Note that 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 32a of the frame member 32 over the entire circumference inside 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. By the positioning steps so far, the positioning of the panel member 31 is achieved. Note that an embodiment in which the positioning step is more easily performed will be described again as a second embodiment.

  The step of manufacturing the door 3a includes a step of bonding and fixing the panel member 31 positioned in the positioning step to the frame member 32 by using urethane foam (bonding step).

  In the bonding step, the space inside the frame member 32 where the panel member 31 is positioned (the space surrounded by the panel member 31, the frame member 32, and the door liner) is filled with urethane foam, so that the panel member 31 It is firmly bonded (secondarily bonded) to the frame member 32. The door 3a is completed through the above-described positioning step, bonding step, and other various steps.

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 hook so that the positioning step is more easily performed. In the following description, emphasis will be placed on portions different from the first embodiment, and description of common portions 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 hang on the outer edge of the front surface of the panel member 31 (a hooked frame portion, a first frame portion). The other upper frame portion 32b1, lower frame portion 32b2, and right frame portion 32b4 are hookless frame portions.

  The state of the positioning step according to the second embodiment is shown in FIGS. The cross sections of the panel member 31 and the frame member 32 shown in these figures correspond to the cross section indicated by the two-dot chain line in FIG. Further, on the lower side of these figures, an enlarged view of a portion surrounded by a solid line is shown.

  In the positioning step, a panel member 31 and a frame member 32 in which a double-sided tape 35 is attached in advance to a portion inside the frame portion 32b of the front portion 32a are prepared. Note that, on the side (left side) where the hooked frame portion is provided, of the portion inside the frame portion 32b of the front surface portion 32a, the attachment of the double-sided tape 35 is omitted.

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 hook), and the panel member 31 is slightly rotated about the left side as an axis. The right side of the member 31 is fitted into the frame 32b. Then, as shown in FIG. 11, the paper tape 3 is closed so as to close the gap between the left side of the front surface 32a and the panel member 31.
(Single-sided tape) 9 is attached. By the positioning steps so far, the positioning of the panel member 31 is achieved.

  According to the positioning step of the second embodiment, it is possible to easily position the panel member 31 as compared with the positioning step of the first embodiment. In other words, 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, the positioning becomes very large. It will be 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 hook, it is only necessary to slightly rotate the panel member 31 while supporting the frame portion with the hook on 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 using the hooked frame, the double-sided tape 35 is provided on the side (left side) where the hooked frame is provided as described above. Can be omitted. Therefore, it is possible to reduce the use amount of the double-sided tape and to suppress the manufacturing cost.

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

3. Others As described above, the door 3 of the first embodiment and the second embodiment has 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, wherein the panel member 31 is fitted and positioned and fixed to the frame portion 32b 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 portion 32b is a hookless frame portion formed so as not to be hooked on the outer edge of the front surface of the panel member 31, and the whole or a part of the hookless frame portion is a panel member 31. Is projected forward from a virtual plane P2 set so as to include the front surface of.

  For this reason, the door 3 can strengthen the protection of the peripheral portion of the panel member 31 while preventing the frame member 32 from covering the whole or a 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 has upper frames corresponding to the upper, lower, left, and right sides of the panel member 31. It comprises a portion 32b1, a lower frame portion 32b2, a left frame portion 32b3, and a right frame portion 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 front opening and a frame portion surrounding the periphery of the panel member. A refrigerator door in which the panel member is fitted and positioned and fixed in the frame portion so that the front surface of the panel member faces forward, and the whole or a part of the frame portion is the panel member. Is a hookless frame formed so as not to be hooked on the front outer edge of the panel member, and the whole or a part of the hookless frame is projected forward from an imaginary plane set to include the front surface of the panel member. Configuration.

  According to this configuration, it is possible to enhance the protection of the peripheral portion of the panel member while preventing the frame member from covering the entire or a part of the front outer edge of the panel member.

  More specifically, as the above configuration, the shape of the panel member is a substantially rectangular shape having upper, lower, left, and right sides when viewed from the front, and the frame portion corresponds to each of the upper, lower, left, and right sides of the panel member. The upper frame, the lower frame, the left frame, and the right frame may be configured.
