Description

  The present invention relates to a refrigerator provided with a drawer container in a storage chamber, and more particularly to a support structure for the drawer container.

  As shown in FIG. 7, the refrigerator compartment (56) in the refrigerator is conventionally provided at the top of the main body as a storage chamber having the largest storage capacity. A so-called chilled chamber (63), which is controlled to about 0 to −3 ° C., which is slightly lower than the temperature of the refrigerator compartment by partitioning with a bottom plate (58) which is a partition, is disposed below the refrigerator compartment. In many cases, a water supply tank (64) for supplying ice making water to the automatic ice making device is installed on the side of the chilled chamber via a partition plate (62).

  A container (65) is housed in the chilled chamber (63) so that it can be pulled out, and this container (65) has one of the ridges (65a) formed on both side walls extending in the front-rear direction. A rail formed on a partition plate (62) that divides the chilled chamber (63) and the water supply tank (64) into the rail (54a) provided on the inner box side wall (54) forming (62a) is engaged so that it can slide back and forth, and when the refrigerator compartment (56) is opened, the container (65) can be pulled out and the stored food can be taken out and stored. ing.

In addition, a vegetable room (59) is provided below the refrigerating room (56) via a bottom plate (58), and the cooling of the vegetable room (59) is performed by using the cold air circulated in the refrigerating room from behind. The upper surface opening is covered with a lid cover and is blown forward from between the upper surface of the vegetable container and the bottom plate (58). The cold air that has reached the front opening of the vegetable compartment (59) descends between the front and left and right peripheral sides of the vegetable container and the wall surface of the vegetable compartment and circulates back to the cooler compartment through the outer bottom surface of the container. The stored vegetables are indirectly cooled from the periphery of the vegetable container to prevent drying. (For example, see Patent Document 1)
JP 2002-277152 A (paragraphs [0018] [0023])

  However, in the support structure of the container (65), one of the left and right rails (62a) (54a) is attached to the inner box side wall (54), and the other forms the bottom surface of the refrigerator compartment (56). Since it is formed on the side surface of the partition plate (62) erected on the bottom plate (58), the height dimensions of the receiving surfaces of the rails (62a) (54a) on both sides are included when assembly dimension errors of each part are included. It is extremely difficult to match, and as a result, as indicated by the two-dot chain line in the figure, the container (65) in the chilled chamber is attached not diagonally but obliquely, and the adjustment work is complicated. It was a thing.

  Further, since the container (65) is placed between the rails (62a) (54a) on both sides so as to be drawable, a dimensional error is taken into consideration between the container (65a) and the protrusion (65a) of the container. Since a relatively large gap was formed, the container (65) fluttered from side to side during sliding and lacked a sense of stability.

  The present invention has been made in consideration of the above points, and improves the design effect by improving the container support method and maintaining the horizontal state, and also reduces smoothness and smooth sliding in the drawer storage operation. An object of the present invention is to provide a refrigerator capable of effectively expanding the storage capacity of the container.

  In order to solve the above-described problems, a refrigerator according to the present invention includes a storage space partitioned in a storage chamber, a container installed in a bottom of the storage space so that it can be pulled out, and a depth below the bottom of the container. It has a slide guide portion formed and a rail portion provided on the bottom surface portion so as to engage with the guide portion, and the slide guide portion and the rail portion are engaged with each other by a concavo-convex mechanism to move left and right. The movement of the container is restricted and the container is slid back and forth.

  In addition, the storage space defined in the storage chamber, a container that can be pulled out on the bottom surface of the storage space, an engagement protrusion formed in the depth direction below the bottom of the container, and the engagement protrusion An engagement receiving groove provided in the bottom surface portion so as to engage with the strip, and when the container is slidably installed at a predetermined position on the bottom portion, the engagement with the engagement convex strip A cold air circulation space is formed between the bottom surface and the bottom surface of the container by engaging and abutting with the receiving groove.

  With this configuration, the container is held by the bottom plate of the storage chamber, and is also restricted from moving left and right even when sliding back and forth, preventing tilting and in a pull-out operation in a design that does not fluctuate left and right. In addition, a configuration with high quality can be obtained, and since the support protrusions on the left and right sides of the container can be eliminated, the width dimension can be expanded, and the substantial storage volume can be increased. Furthermore, the space between the container and the bottom plate can be used as a cold air circulation passage, and the configuration is not complicated as compared with the case where the cold air passage is formed in the partition wall or the like.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view showing the upper part of the refrigerator (1), and a storage space is formed by an inner box (4) provided on the inner surface of the outer box (2) via a heat insulating material (3), and a partition wall Divided into multiple storage rooms according to (5).

  (6) is a refrigerating room disposed at the uppermost part of the main body. A refrigerating room door is pivotally supported on one side of the main body by a hinge, and the front opening is closed by this door.

  In the lower part of the refrigerator compartment (6), a vegetable compartment (9) for accommodating vegetables and the like is formed via a bottom plate (8). Since this vegetable room (9) is basically in the temperature range almost the same as that of the refrigerator room (6), the bottom plate (8) does not require a heat insulation structure and is formed of a plate body that performs a simple partitioning action. Yes.

  Below the vegetable compartment (9), although not shown in the drawing, an ice-making storage compartment and a temperature switching compartment are placed in a relatively small volume via a heat-insulating partition wall (5), and a frozen portion containing frozen food at the bottom. These storage rooms other than the refrigerator compartment (6) are provided with a support frame on the inner side of the door that closes the front opening, and the storage containers held by the support frame are attached to the side walls of the respective storage rooms. The drawer system is slidable back and forth with the arranged rails.

  Thus, at the bottom of the refrigerator compartment (6), the bottom surface is composed of the bottom plate (8) of the refrigerator compartment, and the top plate (11) and the partition plate (12) are arranged on one side wall to form a compartment, A chilled chamber (13) controlled at about 0 to -3 ° C is formed. As shown in FIG. 2, which is a front view, a water supply tank (14) for supplying ice-making water to the ice-making ice storage chamber is provided outside the partition plate (12) constituting one side wall of the chilled chamber (13). It is installed detachably.

  (15) is a container that can be pulled out into the chilled chamber (13), has a box shape with a peripheral side with an open top, has a low front wall and a large front opening, as described above. Stores low-temperature food.

  As shown in FIG. 3, which is an enlarged sectional view of the main part, and FIG. 4, which is an exploded perspective view of each member constituting the chilled chamber, the container (15) is the bottom plate (8) of the refrigerator compartment (6). Guide rails (15a) (15a) provided on the slide rails (8a) (8a) formed on both sides and provided in the depth direction on both sides below the bottom of the slide rail (8a). By being engaged, the weight of the container (15) and the stored food is supported and slidable in the front-rear direction.

  The slide rail (8a) is formed integrally with the bottom plate (8), and guide rails are provided on the outer sides of the rail surfaces (8a) on both sides for placing and contacting the guide rails (15a). (15a) is provided with a slight gap, and the wall step (8b) is erected to refrigerate the space between the container (15) and the bottom plate (8) between the left and right rail surfaces (8a) (8a). It is made into the suction duct (16) which leads to the cooler room of the cool air which circulated through the room (6), and the vegetable room (9) located under that is indirectly cooled by the cold air passing through the duct (16) .

  (17) is a chilled door that holds the chilled chamber (13) in a substantially sealed state together with the top plate (11) and the partition plate (12), and is pivotally supported at the front end of the top plate (11) ( 15) The upper opening on the front surface is covered so as to be openable and closable, and is configured to open and close in conjunction with the drawer and push-in operations of the container (15).

  FIG. 5 shows a more detailed configuration of the present embodiment. The rear portion of the rail (8a) of the bottom plate (8), that is, the container (15) in a predetermined position when the refrigerator compartment door is closed. A concave groove (8c) is formed in the rail surface (8a) extending from the front portion to the rear end portion. And the front end part of the guide protrusion (15a) of the container (15) is engaged with the rail surface (8a) in front of the concave groove (8c), and the concave groove is formed at the rear end of the guide protrusion (15a). (8c) The stopper convex part (15b) which reaches the bottom part of the ditch | groove (8c) is formed in the position which corresponds to the rear-end part.

  In addition, a downwardly inclined portion (8d) toward the final inner portion is formed at the rear end of the concave groove (8c) by bead molding or the like. By pushing the container (15) to a predetermined position, When the chilled door (17) pivots downward along the guide slope and closes the opening of the chilled chamber (13), the container (15) is dropped along the downward slope (8d) at the final position. It is formed so as to be held in a predetermined position automatically.

  Further, as shown in FIG. 3, a locking projection (15c) is provided below the side wall of the container (15), and the upper part of the corresponding side wall of the inner box (4) or the water supply tank (14) Engagement ridges (20) are projected on the inner surface of the partition plate (12) and arranged to overlap on the projected area so as to prevent rattling such as upward movement of the container (15) during sliding I have to.

  With the above configuration, when pulling out the container (15) from the chilled chamber (13), the guide protrusion (15a) of the container (15) moves forward along the rail surface (8a) of the bottom plate (8). The stopper projection (15b) moves forward in the groove (8c) at the rear of the rail. At this time, the guide protrusion (15a) and the rail (8a) are engaged by the concave and convex mechanism by the wall step (8b), and the movement of the guide protrusion (15a) in the width direction is prevented. As a result, smooth sliding operation can be performed.

  Moreover, since the guide ridge (15a) below the container (15) is directly held on the rail (8a) of the bottom plate (8) without any other parts, the horizontal state can be easily held without tilting. Since the guide protrusion (15a) also functions as a reinforcing rib of the container (15), the container (15) can be secured in a more stable state and there is no support protrusion on the left and right sides of the container. , The width dimension can be enlarged, and the substantial storage volume can be increased.

  When the container (15) is pulled forward by a predetermined distance, the stopper convex portion (15b) is in contact with the front end of the concave groove (8c) to prevent further forward movement. As shown in FIG. 5, the chilled door (17) is rotated upward with the side wall of the container (15) as a guide, and there is no hindrance to the forward movement and taking in and out of the food stored in the container.

  Even when the container (15) is pushed in, the same action can smoothly slide backward without rattling to the left and right, and in the final position, the stopper protrusion (15b) is caused by the downward inclined portion (8d) at the rear end of the groove. It can be lowered and stopped without moving at a predetermined position, and the space between the container (15) and the bottom plate (8) can be used as a cold air circulation passage (16), such as in a partition wall Compared with the case where the cool air passage is formed, the configuration is not complicated.

  Next, a second embodiment of the present invention will be described. As shown in FIG. 6 in which the same reference numerals are assigned to the same parts as in the above embodiment, the feature of this embodiment is that the guide protrusion (15a) of the container (15) and the slide rail (8a) of the bottom plate (8). ) Is slightly displaced toward the center, and a predetermined space is formed between the left and right rail surfaces (8a) (8a) to each end portion, and this is provided at the back of the chilled chamber (13). A cooling air passage (18) (18) that blows out in the direction of the arrow from the outlet and a suction duct (19 to the cooler chamber of the cold air that circulates in the refrigerator compartment (6) between the rails (8a) (8a) on both sides (19) ).

  At this time, the guide protrusion (15a) of the container is in contact with the rail surface (8a) of the bottom plate, and the opening of the rear groove (8c) is flush with the guide protrusion (15a). From the relationship with the wall step (8b), the blown cold air passage (18) and the suction duct (19) are clearly separated.
