Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a refrigerator,
More specifically, the present invention relates to a drawer structure of a drawer type door.

[0002]

2. Description of the Related Art In a conventional refrigerator, as shown in FIGS. 1, 6 and 7, for example, a refrigerator body 1 is divided into upper and lower refrigerator compartments 4 and middle freezer compartments 5 by partitions 2 and 3, and a lower vegetable compartment. The drawer is provided with storage cases 5a, 5b, and 6a detachably held on the back sides of doors A, B, and C that open and close respective openings. It is composed of an expression door.

[0003] Guide rails 7 having a substantially U-shaped cross section are disposed substantially horizontally on opposing inner surfaces of the vegetable compartment 6, and support rollers 8 are provided on the front side of the guide rails 7. On the back side of the door C, a door rail 9 'mounted on the support roller 8 and sliding thereon, and a rolling roller 10 rolling along the guide rail 7 at the rear of the door rail 9' are provided. The guide rail 7 and the door rail 9 ′ hold the door body C so as to be able to be pulled out, and when the door body C is fully opened, the stopper 11 at the rear part of the door rail 9 ′ restricts the drawer toward the front. It has become. Also, in recent years, rollers with bearings are often used to reduce the movement of the drawer door. However, in the above-described configuration, when the refrigerator body 1 is placed at an angle or the roller mounting position fluctuates, if the door is fully opened and the hand is released from the handle, the door is closed and the usability is poor. was there.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a refrigerator which does not self-close even if the door of the drawer type door is fully opened and the hand is released from the handle. And

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and comprises a storage room having an opening at the front surface and a substantially horizontal arrangement on opposing inner surfaces of the storage room. A guide rail having a U-shaped cross section, a support roller provided on the opening side with respect to the guide rail, a door body for opening and closing the opening part, and a support roller mounted on the back surface of the door body. A door rail mounted and slidable on the door rail, and a rolling roller provided at the rear of the door rail and rolling along the guide rail, so that the door body can be pulled out by the guide rail and the door rail. In the refrigerator to be held, a stopper of the support roller is provided at a rear portion of the door rail so that the door body does not self-close when the door body is fully opened.

Further, the stopper is constituted by a convex portion formed on an upper portion of the door rail.

[0007] Further, the stopper is constituted by a recess formed in the upper part of the door rail.

Further, the projection and the recess are formed integrally with the door rail.

[0009]

According to the above construction, a stopper is provided at the rear of the door rail, so that the refrigerator does not self-close even if the drawer door is fully opened and the hand is released from the handle.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the accompanying drawings, taking a vegetable room as an example. FIG. 1 is a side sectional view showing an internal configuration of a refrigerator, and FIG. 2 is an exploded perspective view of a vegetable room. In the figure, reference numeral 1 denotes a refrigerator main body, and the main body 1 is divided into an upper refrigerator room 4, a middle freezer room 5, and a lower vegetable room 6 by partitions 2, 3, and the freezer room 5 and the vegetable room 6 are respectively Of the doors A, B, and C that open and close the opening portions.

A guide rail 7 having a substantially U-shaped cross section is disposed substantially horizontally on opposite inner surfaces of the vegetable compartment 6, and a support roller 8 is provided on the front side of the guide rail 7. A door rail 9 mounted on the support roller 8 and sliding on the back side of the door body C, and a rolling roller 10 rolling along the guide rail 7 at the rear of the door rail 9 are provided. The guide rail 7 and the door rail 9 hold the door C so that it can be pulled out.

FIG. 3 and FIG. 4 are enlarged sectional views of a main part showing an embodiment of the present invention. On the upper surface of the rear part of the door rail 9 placed on the support roller 8, there is provided a protruding stopper 11 for restricting and stopping the withdrawal in the forward direction when the door body C is fully opened. A stopper 12 having a convex portion is provided in front of the door C so that the door C does not self-close when fully opened.

FIG. 5 is an enlarged sectional view of a main part showing another embodiment of the present invention. Since the door C does not self-close when fully opened, a stopper 13 having a concave portion is provided in front of the protruding stopper 11. With this configuration, the same effect as that of the stopper 12 having the convex portion is obtained.

In the above construction, the stopper 12 formed of a convex portion or the stopper 13 formed of a concave portion is provided on the upper surface of the rear portion of the door rail 9.
Is provided, the refrigerator is easy to use and does not self-close even when the door C is fully opened and the hand is released from the handle.

[0015]

As described above, according to the present invention, the door body C is fully opened and the hand is released from the handle by providing the stopper 12 formed of a convex portion or the stopper 13 formed of a concave portion on the rear upper surface of the door rail 9. It becomes a convenient refrigerator that does not self-close.
