Reference numeral 10 denotes a drawer-type door provided in the freezer compartment 4. 11 is a drawer-type door provided in the vegetable compartment 5.

  A plurality of door containers 12 are provided in the refrigerator compartment doors 2a and 2b. The door container 12 is provided with a door container for storing a large storage item (for example, a beer bottle) and a door container for storing a small storage item (for example, egg, canned food, etc.). That is, door containers having different sizes are provided.

  In FIG. 2, the refrigerator compartment door 2a is provided with a lowermost door container 14, and two door containers 13 are provided above the lowermost door container 14 with a gap therebetween. In FIG. 2, the lowermost door container 14 is larger than the door container 13. Thereby, a stored item larger than the door container 13 can be stored. In this case, the outside door L1 dimension is 800 to 900 mm. In FIG. 2, such a configuration is adopted, but a configuration having a plurality of door containers may be used as long as the L1 dimension is larger.

  Next, the door inner plate of the refrigerator compartment door will be described with reference to FIGS. 3A is an enlarged perspective view of the inner plate of the refrigerator compartment door of FIG. 1, FIG. 3B is an enlarged explanatory view of the main part of FIG. 3A, and FIG. It is an engagement protrusion enlarged view of 3 (b).

  Reference numeral 15 denotes a door inner plate of the refrigerator compartment door 2a. The door inner plate 15 is formed by heating a thin resin plate, stretching it in a heated state, and further drawing it under vacuum to attract it to a mold. Moreover, the door container 13 is formed with resin by injection molding or the like.

  Reference numerals 16 denote protrusions formed at both ends of the door inner plate 15. The packing 17 is located outside the protrusion 16. Thereby, when the opening of the refrigerator compartment 2 is obstruct | occluded with refrigerator door 2a, 2b, it can prevent that the packing 17 is cooled with the cold in the refrigerator compartment 2. FIG.

  The protrusion 16 is provided with a plurality of locking projections 18 at the protrusions 16a and 16b at both ends. Moreover, the latching protrusion 18 is each provided in the position where protrusion part 16a, 16b opposes.

  The locking protrusion 18 is formed integrally with the door inner plate 15 when the door inner plate 15 is molded. When the locking protrusion 18 is viewed from the direction of the arrow P1, it is a substantially square protrusion, and the height dimension is 5 to 8 mm and the width dimension (D) is 12 to 15 mm.

  As shown in FIG. 3C, the upper width dimension D1 of the locking projection 18 is smaller than the lower width dimension D. That is, the locking protrusion 18 satisfies D1 <D. For example, D1 is 10 mm to 13 mm, and is about 2 mm smaller than D. Thereby, when attaching the door container 13 to the door inner board 15 by the latching protrusion 18, the engaging part 20 by the side of the door container 13 can be easily engaged with the latching protrusion 18. FIG.

  Further, a plurality of locking protrusions 18 are provided in the height direction of the protruding portions 16a and 16b. Thereby, the user can change the attachment height of the door container 13 according to the use condition of the door container 13.

  Next, the door container 13 will be described more specifically with reference to FIGS. FIG. 4 is a perspective view of the door container 13. FIG. 5 is an enlarged view of a main part in a state in which the door container 13 is attached to the refrigerator compartment door 2a. As shown in FIG. 2, the door container 13 is attached to the refrigerator compartment door 2 a by the protruding portion 16 of the door inner plate 15. In the present embodiment, the two door containers 13 are attached between the projecting portions 16a and 16b which have the inter-container dimension (H) in the vertical direction and face each other. Since the door container 13 stores small items, the inter-container dimension (H) (see FIG. 2) is smaller than the distance from the lowermost door container 14. That is, the inter-container dimension (H) (see FIG. 2) of the door container 13 is a dimension obtained by adding the dimension necessary for taking out from the door container 13 to the actual dimension of the stored item.

  Reference numeral 19 denotes a presser portion provided at both ends of the door container 13 and having a shape protruding in the width direction. When the door container 13 is attached to the projecting part 16, the presser part 19 is in contact with the end of the projecting part 16 in the height direction and regulates the rotational movement of the door container 13.

  Next, the attachment structure to the door inner board 15 of the door container 13 is demonstrated using FIG. 4, FIG. The door container 13 is attached when the engaging portion 20 engages with the locking protrusion 18 of the door inner plate 15. Here, in the door container 13, the dimension from the position (point A in FIG. 5) where the engaging portion 20 and the locking projection 18 are in contact to the presser portion 19 (point B in FIG. 5) is L2. Further, the dimension between the upper portion of the protrusion 16 on the door inner plate 15 side (point C in FIG. 5) and the position where the locking projection 18 and the engaging portion 20 contact (point D in FIG. 5) is L3. . Then, L1 and L2 are provided so as to have substantially equal dimensions. To be precise, L2> L3.

  The shape of the locking projection 18 having the relationship of D1 <D described above assists this engagement relationship. In other words, even when the dimensions of L2 and L3 are substantially the same, the engaging relationship of the engaging portion 20 is possible if the locking protrusion 18 has a relationship of D1 <D. In addition, it is preferable to configure so that L2> L3 exactly. The presser part 19 is provided over the entire length of the door container 13 in the height direction, and abuts on the upper surface 16 a of the protruding part 16.

  Reference numeral 21 denotes a flange that is an upper portion of the door container 13 and is provided so as to protrude outward in accordance with the protruding dimension of the engaging portion 20. When the door container 13 is attached to the protruding portion 16, the flange 21 contacts the door inner plate 15 and forms a space between the outer side surface of the door container 13 and the inner side surface 16 b of the protruding portion 16. The locking projection 18 and the engaging portion 20 are located in this space. Further, the engaging portion 20 is key-shaped (substantially L-shaped), and when engaging with the locking projection 18, the two surfaces come into contact with the locking projection 18. With the above configuration, the downward and forward movement of the door container 13 is restricted by the engagement relationship between the key-shaped engaging portion 20 and the locking protrusion 18. Further, the movement of the door container 13 to rotate in the vertical direction is regulated by combining the relationship between the presser portion 19 and the protruding portion 16 and the relationship between the engaging portion 20 and the locking protrusion 18.

  Next, the locking device for the door container 13 will be described with reference to FIGS. FIG. 6 is a diagram illustrating a state in which the slide lock portion of the locking device protrudes in the locking direction. FIG. 7A is a diagram illustrating a state in which the slide lock portion of the lock device does not protrude in the lock direction. FIG. 7B is a diagram illustrating that the sliding surface of the slide lock portion hits the locking projection and slides. FIG. 8 is a view showing a state in which the cover of the lock device is removed in the state shown in FIG.

  The lock device 22 shown in FIGS. 6 to 8 includes an operation unit 23 attached to the outer surface of the door container 13 shown in FIG. 4 and a slide lock unit 24 located in a space formed by the flange 21. The operation unit 23 and the slide lock unit 24 are integrally provided. And the operation part 23 moves integrally using the coil spring 25, as shown also in FIG. That is, one end of the coil spring 25 is fixed to the door container 13 side, and the other end is fixed to the attachment portion 23a of the operation portion 23 (state in FIG. 8). And the locking device 22 moves in the front-back direction (left-right direction in FIG. 7) in the recessed part 26 made in the outer surface of the door container 13. At this time, a rail is formed on the lock device 22 side and a rail groove is formed on the concave portion 26 side, and by combining them, the left and right slide of the operation unit 23 of the lock device can be smoothly performed.

  In the state of FIG. 6, the slide lock portion 24 located in the space is in a position close to the locking protrusion 18. This position is a position where, when the door container 13 is attached to the door inner plate 15, a part of the slide lock portion 24 is in contact with or close to the locking projection 18, and the coil spring 25 is contracted. It is. When the operation unit 23 is moved in the P4 direction as shown in FIG. 7A, the slide lock unit 24 is set to a position where it does not come into contact with or close to the locking projection 18.

  When the coil spring 25 is extended, in other words, unless the lock device 22 is displaced from the state shown in FIG. 6 to the state shown in FIG. 7A, the door container 13 has the slide lock portion 24 hooked on the locking protrusion 18 and the door The inner plate 15 does not come off. That is, when the locking projection 18 and the engaging portion 20 are engaged by the elastic force of the coil spring 25, the slide lock portion 24 is regulated so as to be positioned below the locking projection 18.

  Therefore, when removing the door container 13 attached to the door inner plate 15, when the operation part 23 of the locking device 22 is moved in the direction of the arrow P <b> 4, the slide lock part 24 moves away from the locking protrusion 18, and the door container 13 is moved. Is easily removed upward. By adopting such a configuration, the engagement relationship between the engagement protrusion 18 and the engagement portion 20 does not have to be a conventional fitting state (press-fit state). 6 to 8 is a guide pin for restricting the movement of the slide lock portion 24. The protrusion 27 provided on the upper portion of the slide lock portion 24 shown in FIGS. Here, the movement of the slide lock portion 24 in the direction of the arrow P3 is restricted.

  Reference numeral 28 denotes an inclined surface provided in the slide lock portion 24. By providing the inclined surface 28, the engaging portion 20 on the door container 13 side can be engaged with the locking projection 18 without operating the operating portion 23. That is, when the inclined surface 28 is not provided, the slide lock portion 24 hits the locking projection 18, and the door container 13 cannot be incorporated into the door inner plate 15 any more. However, by providing the slide lock portion 24 with the inclined surface 28 as shown in FIG. 7 (b), when the door container 13 is pushed slightly downward, the inclined surface 28 hits the locking projection 18 and the slide lock portion 24 is moved. Slid out (slide) in the direction of arrow P4 in FIG. That is, when the inclined surface 28 comes into contact with the upper portion of the locking projection 18, the slide lock portion 24 moves forward against the elastic force of the coil spring 25 and gets over the locking projection 18. Accordingly, the drag force of the coil spring 25 pulling the slide lock portion 24 is overcome, the coil spring 25 is extended, and the slide lock portion 24 is displaced in the direction of FIG. It is engaged with the protrusion 18.

  Further, as shown in FIG. 4, the cover 23 </ b> C of the operation portion 23 protrudes outward at the position of the coil spring 25, and has a hollow portion 23 d at the top and bottom thereof. That is, the operation part 23 is provided with a cover 23C having a convex part from the center, and the coil spring 25 is provided in the convex part. As a result, the user's finger is easily hooked on the recess 23d so as to straddle the coil spring 25, and the user's finger sufficiently comes into contact with the operation portion. Thus, the user can operate the operation unit 23 while holding the door container 13, and can easily change the position of the door container 13.

  Next, FIG. 9 is a diagram illustrating a relationship between the operation unit 23 of the lock device 22 and the rotation locus R1 of the refrigerator compartment door 2a. In FIG. 9, when the refrigerator compartment door 2a opens and closes, the operation part 23 of the locking device 22 provided on the anti-hinge side of the door container 13 enters the inside of the rotation locus R1 of the refrigerator compartment door 2a. That is, when the rotation locus R2 of the operation unit 23 accompanying the opening / closing operation of the refrigerator compartment door 2a is not located inside the rotation locus R1 of the refrigerator compartment door 3, the dimension between the refrigerator compartment door 2a and the refrigerator compartment door 2b. W must be increased by the size. In this way, by placing the rotation locus R2 of the operation unit 23 inside the rotation locus R1, the gap dimension W between the refrigerator compartment door 2a and the refrigerator compartment door 2b need not be enlarged. In addition, this is an example in the case of providing the rotation partition 34 in the refrigerator compartment door 2a side. When the rotation partition 34 is provided on the refrigerator compartment door 2b side, the rotation locus R2 needs to be set inside the locus R3 passing through the end of the rotation partition 34 on the refrigerator compartment door 2a side.

  Next, an embodiment of a locking device 29 different from the locking device 22 shown in FIG. 7 will be described with reference to FIGS.

The fulcrum 31 is provided on the outer surface of the door container 13, and is located in front of the door container (on the left side in FIGS. 11 and 12) with respect to the engaging portion 20. Here, the front means a direction from the door inner plate 15 toward the refrigerator compartment 2 in a state where the refrigerator compartment door 2a is closed. Further, in the state of FIG. 11 in which the locking projection 18 is engaged with the engaging portion 20, the fulcrum 31 is located in front of the locking projection 18 (left side in FIG. 11). In addition, when the door container 13 is attached, it is provided so that the latching protrusion 18 may be located in the rotation locus of the rotation lock portion 30. Thereby, even if a force in the lifting direction is applied to the door container 13, the rotation lock part 30 is in contact with the lower part of the locking projection 18, so that the door container 13 can be prevented from coming off.

  As shown in FIGS. 11 and 12, if the operation unit 32 is not operated so as to resist the torsion spring 33, there is a contact or proximity relationship between the rotation lock unit 30 and the locking projection 18. Never leave. That is, when the door container 13 is attached to the door inner plate 15, the relationship between the rotation lock part 30, the engagement part 20, the torsion spring 33, and the locking projection 18 so that the door container 13 is not easily detached. Therefore, the operation of the door container 13 is regulated. On the other hand, when the user operates the operation unit 32 as described above, the rotation lock unit 30 rotates against the torsion spring 33. Then, the locking projection 18 and the rotation lock part 30 are separated as shown in FIG. In this state, the user can easily remove the door container 13 from the door inner plate 15 by further lifting the door container 13 upward.

  In other words, the locking device 29 of the door container 13 is in the state shown in FIG. 11 before being attached to the door inner plate 15. When this is attached to the door inner plate 15, the position of the rotation lock portion 30 is set as shown in FIG. In this manner, the locking projection 18 is passed through in the state where the operation portion 32 is rotationally displaced, and the state shown in FIG. 11 is obtained. Further, even if the inclined surface 30a of the rotation lock portion 30 is used to bring the inclined surface 30a of the rotation lock portion 30 into contact with the locking projection 18 and the door container 13 is pressed against the locking projection 18 side, the door container 13 can be attached to the door inner plate 15.

  By adopting such a configuration, the door container 13 can be prevented from being detached from the door inner plate 15 even when an external force in a direction of pushing upward is applied to the door container 13.

  Further, when the user operates the operation portion 23 provided on the door container 13, the slide lock portion 24 that is brought into contact with or close to the locking projection 18 can be easily released, and the attachment position of the door container 13 can be easily set.
