Description

  The present invention relates to a refrigerator provided with a storage pocket attached to the inner wall surface of an opening / closing door.

  Currently, the mainstream refrigerator is provided with an opening / closing door on the front surface of the refrigerator compartment, and a plurality of storage pockets arranged vertically on the inner wall surface of the opening / closing door. These storage pockets have a large storage pocket for storing bottles at the bottom, and a small storage pocket for storing small food items such as eggs and tubes at the top.

  By the way, the door pocket inside the door is not attached with a dedicated pocket for storing small items such as a seasoning case for a lunch box or fine seasonings such as mayonnaise that can be used once. Therefore, it was scattered in the refrigerator, and wasted such as being disposed of without being mixed with other foods. Moreover, even if it was stored in the door pocket, there was a high risk that it would move and fall in the pocket when the door was opened and closed.

  In order to solve this problem, in the conventional example, a small pocket having an open upper surface is provided on the lower side of the door pocket so as to be drawn forward or rotatable. According to this conventional example, food such as fine seasonings can be stored and placed in the accessory pocket, so that the inside of the refrigerator door can be smoothly arranged. Moreover, since the space below the door pocket, which tends to be a dead space, can be used, the storage efficiency can be improved.

In addition, the same site | part, an arrow, etc. are shown with the same code | symbol, and the overlapping description is abbreviate | omitted.
(First embodiment)
First, with reference to FIG. 1 and FIG. 6, the schematic structure of the refrigerator provided with the accessory pocket based on 1st Example is demonstrated. Here, FIG. 1 is a schematic configuration diagram of the refrigerator according to the first embodiment, (a) FIG. 1 is an external view of the main part in a state in which the open / close door of the refrigerator is released, and (b) is a drawing out the accessory pocket. The perspective view of a state and (c) figure have shown the perspective view of the state which accommodated the accessory pocket. FIG. 6 is a reference diagram of the usage state of the accessory pocket according to the first embodiment. In addition, in the balloon of (a) figure, the external appearance of the 2nd storage pocket which accommodated the accessory pocket is shown.

  As shown to Fig.1 (a) figure, the refrigerator 1 which concerns on this Example has attached the opening-and-closing door 4 so that the opening part 3 of the front surface of the refrigerator housing 2 which incorporated the heat insulating material may be covered. Generally, the refrigerator 1 employs a structure in which the front surface of the refrigerator housing 2 is divided into a plurality of parts by a partition plate 5 and the divided storage parts 6 are covered with the opening / closing door 4 or a drawer door (not shown). In this embodiment, the present invention can be applied to the open / close door 4 that can be opened / closed by one or both openings via the hinge mechanism 7. In this embodiment, the case of the refrigerator 1 in which the front face of the refrigerator compartment (housing portion 6) formed at the uppermost part is constituted by a double door opening / closing door 4 is described. Of course, the present invention can also be applied to a one-door type refrigerator in which the front surface of the refrigerator housing 2 is constituted by a single door.

  The open / close door 4 according to this embodiment includes a plurality of storage pockets 100 on the inner surface 8 thereof. For example, in this embodiment, a large first storage pocket 101 capable of storing a plastic bottle or bottle is provided at the bottom, and a small size capable of storing small food items such as eggs and tubes is provided above the first storage pocket 101. One or a plurality of second storage pockets 110 are provided. In this embodiment, the first storage pocket 101 is fixedly provided. However, the height at which the second storage pocket 110 is attached by an attachment structure (not shown) can be adjusted.

  And one of the big features of the refrigerator 1 according to this embodiment is that a thin accessory pocket 150 whose upper part is opened on the lower surface of the second storage pocket 110 fixedly attached to the inner surface 8 of the door 4 of the refrigerator 1. The small pocket 150 is attached to be rotatable up to 90 degrees through the rotary shaft 20 provided in front of the end of the opening / closing door 4 of the second storage pocket 110 on the hinge mechanism 7 side. .

  That is, in the conventional refrigerator, there is a problem that there is no space for storing small items such as seasoning cases for lunch boxes or fine seasonings such as mayonnaise that can be used up once. Small items such as seasonings are usually stored in the storage pocket 100, but there is a problem that the bottom of the storage pocket 100 is lost, resulting in a lost child. Therefore, in the conventional example, a structure in which a thin accessory pocket 150 is stacked at the lower part of the storage pocket 100 so that it can be pulled out has been proposed.

  However, this conventional example does not solve the problem of breakage of the accessory pocket 150 or the like that occurs when the accessory pocket 150 is pulled out and the door is accidentally closed. For this reason, from the viewpoint of safety, there is a problem that the structure of the conventional example cannot be implemented as it is. Therefore, the inventors have conceived that the rotary shaft 20 for pulling out the accessory pocket 150 is provided on the bottom surface of the second storage pocket 110 on the hinge mechanism 7 side of the open / close door 4. With the arrangement of the rotating shaft 20, the end portion of the pulled out accessory pocket 150 is divided into the end portion of the other opening / closing door 4 and the refrigerator compartment (storage portion 6) up and down, or the partition shelf 9. Even when hitting the food to be stored, the small pocket 150 can be closed around the rotating shaft 20 without being damaged in conjunction with the closing operation of the open / close door 4 that rotates around the hinge mechanism 7.

  However, according to the experimental verification by the present inventors, it has been found that the accessory pocket 150 may be damaged in a special state as shown in FIG.

  That is, as shown in FIG. 6A, the sum of the length L2 from the hinge mechanism 7 to the rotary shaft 20 and the length L3 from the rotary shaft 20 to the end of the small accessory pocket 150 is the sum. However, when the length L1 between the hinge mechanism 7 and the free end of the open / close door 4 is larger than the length L1, the end of the small accessory pocket 150 that is pulled out may hit the open / close door 4.

  In this case, if the rotation angle Θ <b> 1 with which the accessory pocket 150 is pulled out is 90 degrees, the stress applied to the end of the accessory pocket 150 against the other opening / closing door 4 acts in the direction of closing the accessory pocket 150. The opening / closing door 4 can be closed without being damaged. Furthermore, even if the end of the accessory pocket 150 hits the partition shelf 9 or the stored food, the door 4 can be closed by the same action as described above.

  On the other hand, if the accessory pocket 150 is rotated to a rotation angle Θ1 at which the end of the drawn accessory pocket 150 does not hit the other opening / closing door 4, damage due to a collision with the other opening / closing door 4 can be avoided. However, in this case, it is necessary to prevent the attachment position of the accessory pocket 150 from overlapping with the attachment position of the partition shelf 9 so that the end of the accessory pocket 150 does not collide with the partition shelf 9. However, in this case, as shown in FIG. 6B, the problem that the end portion of the accessory pocket 150 collides with the food to be stored remains.

  Further, as shown in FIG. 6A, depending on the shape of the end of the accessory pocket 150 that contacts the other opening / closing door 4, the accessory pocket is rotated at a specific angle with the rotation angle Θ1 exceeding 90 degrees. When the end of 150 collides with another open / close door 4, it has been confirmed by experimental verification that the stress of the collision becomes a force for damaging the accessory pocket 150.

  Therefore, as shown in FIG. 1, in the present invention, the rotation shaft 20 is provided in front of the bottom surface of the second storage pocket 110 on the hinge mechanism 7 side, and the rotation angle Θ <b> 1 of the accessory pocket 150 about the rotation shaft 20 is set. It was set so as to be rotatable within a range of 90 degrees. With this structure, the upper portion of the accessory pocket 150 concealed by the second storage pocket 110 at the time of storage can be opened within a range sufficient to put in or out the accessory food or identify the stored accessory food. . In addition, if the rotation angle Θ1 is 90 degrees, the problem of damage due to the collision can be reduced.

  Another major feature of the refrigerator 1 according to this embodiment is that the rotary shaft 20 is provided with a spring 31 for returning the accessory pocket 150 drawn out by rotation.

  That is, as described above, in this embodiment, the spring 31 is provided on the rotary shaft 20 in order to reduce the problem of breakage due to the collision. The spring 31 only needs to act so that the rotation angle Θ1 does not rotate 90 degrees or more. However, in this embodiment, in consideration of the consistency and accuracy of merchantability, a spring 31 is employed that acts so that the accessory pocket 150 pulled out by rotation can be restored to its original storage position.

  According to this embodiment provided with the spring 21, the accessory pocket 150 can be rotated and pulled out with one hand from the state in the balloon shown in FIG. Then, if the hand is released from the pulled-out state in FIG. 5B, the original storage state can be restored as shown in FIG.

  Hereinafter, a more detailed description will be given with reference to FIGS. Here, FIG. 2 is an exploded view of parts of a storage pocket provided with accessory pockets.
