Description

TECHNICAL FIELD The present invention relates to a refrigerator door having a door stopper.

2. Description of the Related Art In recent years, it has become common in refrigerator doors to integrally form a stopper that regulates the opening angle of the door with the door. Such a refrigerator will be described with reference to FIGS. 3 to 5.

In the figure, reference numeral 1 denotes a body of a refrigerator, and a freezer compartment door 2 and a refrigeration compartment door 3 are attached to a front surface of the refrigerator body in a vertically rotatable manner by a hinge. The main body 1 is composed of an outer box 4, an inner box 5, and a heat insulating material 1'filled between the boxes 4 and 5. The refrigerating compartment door 3 (the freezing compartment door 2 has a similar structure, the refrigerating compartment door 3 will be described as an example) has an outer plate 6 and an inner plate 7 whose side surfaces are bent in a U shape, and both plates 6 The decorative plate 8 is made of synthetic resin and is provided to cover the upper and lower peripheral edges of the decorative plates 7 and 7, and the heat insulating material 9 is filled between the plates 6 and 7 and the decorative plate 8. Reference numeral 10 is a gasket attached to the door 3 and in contact with the main body 1. A hinge 11 is attached to the bottom surface of the main body 1 and has a pin 12 to be inserted into the bottom surface of the decorative plate 8 of the door 3.

A leg 13 for adjusting the height of the main body is adjustably attached to the bottom of the hinge 11 with a screw. Reference numeral 14 denotes a stopper attached to the bottom surface of the decorative plate 8 in the vicinity of the pin 12 so that the opening angle of the door 3 is regulated by hitting the end surface 11a of the hinge 11 (indicated by a chain line in FIG. 4). It has become.

The stopper 14 is formed by inserting the protrusion 15 into the hole 17 of the decorative plate 8 and fixing the other portion with a screw 18. Also screws
In order to fix at 18, a substantially U-shaped reinforcing plate 19 is attached to the heat insulating material 9 side of the decorative plate 8. A hole 20 is also made in the reinforcing plate 9 and the protrusion 15 is inserted.

However, the structure as described above has a drawback that the door angle is deviated due to the loosening of the screw 18 and the stopper effect is remarkably lowered during long-term use. This is for the following reason.

That is, the stopper 14 is placed between the decorative plates 8 and the reinforcing plate 19
Since it is mechanically attached to the screw 18 by the screw 18, the screw 18 loosens and rotates during long-term use. In order to prevent this, a protrusion 15 is usually provided on a part of the stopper 14 and inserted into the decorative plate 8 and the holes 17 and 20 formed in the reinforcing plate 19 to prevent rotation. Therefore, with the stopper 14,
A slight gap is provided between the decorative plate 8 and the holes 17 and 20 of the reinforcing plate 19. For this reason, there is an extremely small amount of rattling, the mounting of the stopper 14 starts to loosen during long-term use, and the door opening and closing angle at the initial design changes due to the inclination of the stopper 14 and the like. Further, the holes 17 and 20 formed in the decorative plate 8 and the reinforcing plate 19 respectively have a drawback that the attachment portion of the stopper 14 becomes weak in strength.

Therefore, in view of the above-mentioned drawbacks, the present invention integrally forms a stopper and a decorative plate, and further provides a reinforcing rib on the inner surface of the decorative plate to prevent the stopper from loosening and to secure the strength by eliminating the hole in the decorative plate. The present invention is to provide a decorative plate that always has a stable stopper effect.

Means for Solving the Problems To achieve this object, the technical means of the present invention is to provide a first flange and a second flange of the decorative plate on the inner surface where the stopper of the decorative plate is located. It is configured by providing both flanges and continuous reinforcing ribs.

Action The action by technical means is as follows.

That is, the door is opened, and the main body stopper protruding from the refrigerator main body and the force concentrated on the stopper when the stopper hits are distributed to the entire decorative plate, and the first flange and the second flange of the decorative plate are also distributed. Since the and are continuously connected by the reinforcing ribs and are further in the form of a lattice, the overall rigidity is increased.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. It should be noted that the same components as those of the related art are denoted by the same reference numerals and detailed description thereof is omitted.

Reference numeral 21 denotes a door attached to the front surface of the main body 1, and an outer plate 23 having a flange 22 extending in opposite directions by folding side edges.
An inner plate 24 made of a synthetic resin, an outer plate 23 and a decorative plate 25 attached to the inner plate 24 at the top and bottom, and a heat insulating material 26. The decorative plate 25 is made of synthetic resin, and a first flange 27 located along the inner surface of the outer plate 23 and a second flange 28 located along the inner surface of the inner plate 24 are integrally formed. Also,
The first flange 27 and the second flange 28 are continuously and integrally formed with a plurality of lattice-like reinforcing ribs 29. A stopper 30 is integrally formed on the rear surface side facing the reinforcing rib 29. The door 21 has a hole 34 into which a pin 33 of a hinge 32 attached to a partition wall 31 that divides a freezing room (not shown) and a refrigerating room (not shown) of the main body is inserted.
It is formed on the outer side of 30, and the end face of the hinge 32 and the stopper 30 abut when the door 21 is opened (shown by the dashed line in FIG. 1) to restrict further opening.

That is, open the door 21 and hinge 32 protruding from the refrigerator body.
When the stopper 30 hits the end face of the, the force applied to the stopper 30 is dispersed over the entire decorative plate, and the decorative plate 25
First flange 27, second flange 28 and reinforcing rib 29 of
Since it is connected continuously with and is made into a lattice shape, the overall rigidity is increased. Furthermore, the foam insulation material is densely filled to the inside of the lattice to improve the strength of the entire structure, and even if the door is opened and closed for a long period of time, there is no "loose" or "misalignment" of the stopper. No, you can always maintain a stable door opening angle.

Effect of the Invention The present invention improves the strength of the stopper by forming the stopper integrally with the decorative plate and providing continuous reinforcing ribs between the first flange and the second flange on the inner surface of the decorative plate. There is no "looseness" or "rattle" in the stopper, and you can always maintain a stable door opening angle. Furthermore, parts such as paper tape, which has conventionally sealed each hole of the door stopper mounting screw and door stopper rotation prevention boss, are no longer required, leading to reduction of materials and assembly man-hours, and door stopper of stable performance at low cost. Supply is possible.
