Description

refrigerator {refrigerator}

The present invention relates to a refrigerator having a shelf assembly provided with a cold air cover for preventing leakage of cold air in each storage space.

BACKGROUND ART In general, a refrigerator is a home appliance that is provided to store various foods or beverages for a long time with cold air generated by using the circulation of a refrigerant according to a refrigeration cycle.

Such a refrigerator provides a storage compartment for storing stored goods such as food or beverage to be stored, and the storage compartment is divided into a plurality of storage spaces using a plurality of shelf assemblies so that the storage compartments can be stored separately according to the type or size of each stored product. done so as to

In particular, in recent years, a cold air cover is additionally provided to the shelf assembly to prevent the cold air from leaking into the storage space even when the refrigerator door is opened.

This cold air cover is configured to open the front of the storage space when the storage is taken out. That is, the cold air cover is accommodated in the receiving groove when the storage is taken out while the receiving groove is formed on the bottom surface of the frame frame constituting the shelf assembly so as not to interfere with the taking out of the stored material.

In this regard, Korean Patent Laid-Open No. 10-2008-0111165, Korean Patent Laid-Open No. 10-2010-0128616, Korean Patent Laid-Open No. 10-2011-0052826, Korean Patent Laid-Open No. 10-2019-0133875, Republic of Korea Publication As disclosed in Patent No. 10-2020-0008752, etc.

However, in the conventional shelf assembly having the cold air cover described above, after the cold air cover is completely taken out from the edge frame, it is rotated about the hinge axis and is positioned to block the storage space. There was a problem.

That is, when the cold air cover is dropped from the frame frame, excessive shaking is generated due to the instantaneous inertia caused by the weight of the cold air cover and collides with the storage inside the storage space.

In particular, the above-described impact causes instantaneous noise, which causes problems such as surprise to consumers, as well as concerns about damage and breakage due to impact.

Of course, in the prior art, there has been an effort to apply a vibration / sound insulation material for preventing (or reducing) the impact caused by the cold air cover collides with the edge frame or storage.

However, the above structure has a problem that not only requires a separate operation for attaching or combining the vibration/sound insulation material, but also increases the manufacturing cost due to an increase in the number of parts.

For this reason, in recent years, various studies have been made to reduce the impact noise generated when the cold air cover is pulled out without providing a separate attachment or combination.

As shown in these drawings, the refrigerator of the present invention is a convertible type refrigerator that can be provided alone while the storage compartment is divided into a plurality of storage spaces by each shelf assembly 300 and the cold air cover 400 . do that as an example.

In particular, in the refrigerator of the present invention, the impact noise to the storage or collision with the guide part is generated when the cold air cover is rotated downward from the guide space to block the storage space through the additional provision of the limiting part and the contact part. This was done to reduce the impact noise.

The structure of the preferred embodiment of the refrigerator of the present invention will be described in more detail for each configuration as follows.

First, the refrigerator according to the embodiment of the present invention includes the cabinet 100 .

The cabinet 100 is configured to form the exterior of the refrigerator while providing a storage room therein.

The cabinet 100 is formed as a cylindrical body opened to the front, and the storage chamber is used as a space for storing various kinds of storage while forming an internal space of the cabinet 100 .

2 to 5, the cabinet 100 may include an outer case 110 forming an outer wall and an inner case 120 forming an inner wall.

In this case, although not shown, a heat insulating material or a foam material may be filled between the outer case 110 and the inner case 120 . Of course, the outer case 110 and the inner case 120 of the cabinet 100 may be formed as a single body.

In addition, the storage compartment may be provided as one, or two or more may be provided in plurality. In the embodiment of the present invention, it is assumed that only one storage compartment is provided.

Next, the refrigerator according to the embodiment of the present invention includes a door 200 .

The door 200 is installed to open and close the open front of the cabinet 100 and is configured to open and close the storage compartment.

The door 200 may be a rotary door or a drawer-type door. In addition, the door 200 may be one or a plurality of two or more.

In the embodiment of the present invention, the door 200 is provided as an example even though the door 200 is a rotatable door.

Next, the refrigerator according to the embodiment of the present invention includes the shelf assembly 300 .

The shelf assembly 300 is configured to divide the storage compartment into a plurality of storage spaces. That is, the inside of the storage chamber may be formed of a plurality of storage spaces by the shelf assembly 300 .

In addition, the mounting protrusions 130 are formed to protrude from both side walls of the cabinet 100 , and the shelf assembly 300 is installed so that both ends are mounted on each of the mounting protrusions 130 . Of course, mounting grooves (not shown) are formed in recesses on both side walls of the cabinet 100, and the shelf assembly 300 may be installed so that portions of both ends are recessed into the mounting grooves to be mounted, The shelf assembly 300 may be installed while both the mounting protrusions 130 and the mounting grooves are formed on both side walls of the cabinet 100 .

Two or more shelf assemblies 300 may be provided in plural, whereby a storage space is formed between the cabinet 100 and the shelf assembly 300 and a storage space is also formed between each shelf assembly 300 . can be

6 to 12 are views illustrating a shelf assembly and a cold air cover of a refrigerator according to an embodiment of the present invention.

As shown in these drawings, the shelf assembly 300 includes a shelf 310 and a guide part 320 .

Here, the shelf 310 is a portion provided as an area on which the storage material is placed, and is formed of a flat plate material.

More specifically, the shelf 310 may be formed of a mounting plate 311 and an edge frame 312 .

In this case, the mounting plate 311 may be made of a material that can see through so as to check the inside of the storage space located at the bottom thereof. The transparent material may include glass or transparent plastic.

In addition, the edge frame 312 is a portion formed along the circumference of the mounting plate (311).

The edge frame 312 is provided as a portion to be placed on the mounting protrusion 130 in the cabinet 100 . That is, in the case of the placing plate 311, since it is formed of a plate, when it is configured to be placed directly on the placing protrusion 130, the weight of the stored material is concentrated on the placing portion on the placing protrusion 130, there is a risk of damage. In consideration of this, by providing the edge frame 312 , it is possible to prevent damage to the mounting plate 311 .

The edge frame 312 may be formed integrally with the mounting plate 311 through molding. Of course, the frame 312 and the mounting plate 311 may be manufactured separately from each other and then combined with each other to form an integral body.

In addition, the guide part 320 is configured to provide a guide space 301 for the sliding operation of the cold air cover 400 to be described later.

The guide part 320 is formed to extend from both sides of the bottom of the edge frame 312 and is formed to be arranged side by side with the edge frame 312 .

That is, between the upper surface of the guide part 320 and the lower surface of the edge frame 312 , a guide space 301 that can be moved while the cold air cover 400 is placed is formed.

Accordingly, the cold air cover 400 is maintained stored in the guide space 301 when not in use, and is withdrawn from the guide space 301 when the cold air cover 400 is used, and then the shelf assembly 300 ) is positioned to block the open front of the storage space located at the bottom.

That is, the upper surface of the guide part 320 is provided as an area for sliding movement of the cold air cover 400 .

In addition, guide grooves 321 are formed in the side surfaces (facing surfaces between the two guide parts) of the guide part 320 , respectively. At this time, the guide groove 321 is a groove formed along the sliding movement direction of the cold air cover 400 and serves to guide the movement of the cold air cover 400 with respect to the hinge shaft 410 .

In addition, a hinge groove 322 is formed extending from the front end of the guide groove 321 . The hinge groove 322 is a groove provided so that the hinge shaft 410 of the cold air cover 400 can be rotated, and extends from the guide groove 321 and from the bottom of the front end of the guide groove 321 . It is formed to be indented.

In addition, the front surface of the guide part 320 is formed to protrude more forward than the front surface of the edge frame 312 . That is, the cold air cover 400 positioned in front of the guide part 320 is placed on the shelf 310 by positioning the guide part 320 more forward than the shelf (in particular, the frame frame) 310 . It is designed not to collide with the storage or collide with the edge frame 312 or the guide part 320 of the shelf assembly 300 positioned below it. This is as shown in FIGS. 8 and 10 and FIGS. 13 to 16 attached thereto.

In particular, the front surface of the guide part 320 is formed to be round. This round is formed in a shape in consideration of the rotation of the cold air cover 400 so that the contact portion 600 to be described later does not collide and interfere when the cold air cover 400 to be described later is rotated around the hinge groove 322 .

Next, the refrigerator according to the embodiment of the present invention includes a cold air cover 400 .

The cold air cover 400 serves to block the open front of each storage space (a space created by a plurality of shelf assemblies) to minimize the unwanted outflow of cold air existing in the corresponding storage space.

The cold air cover 400 is formed of a flat plate material, and preferably may be formed of a material that can see through so that the inside of the storage space can be checked.

The cold air cover 400 is accommodated in each shelf assembly 300 to open the front of the storage space below it, or is drawn out from the corresponding shelf assembly 300 to block the front of the storage space below it. is installed

More specifically, the cold air cover 400 is installed between the edge frame 312 and the guide part 320 constituting the shelf assembly 300 to slide and move in a state where both ends are accommodated.

In addition, the cold air cover 400 is provided with a hinge shaft (410). The hinge shaft 410 is configured to guide the movement while forming the rotational center of the cold air cover 400 while preventing vertical shaking when the corresponding cold air cover 400 is slidably moved.

The hinge shaft 410 is preferably configured to be rotated only within the hinge groove 322 while being prevented from being rotated while it is being moved along the guide groove 321 formed in the guide part 320, and for this purpose, the hinge The shaft 410 is preferably formed in a non-circular round structure such as an ellipse or a track type.

At the same time, a support rib 420 for forming the hinge shaft 410 is protruded from the bottom surface of the cold air cover 400 , and the hinge shaft 410 is formed from an outer wall surface of the support rib 420 . The guide groove 321 of the guide part 320 is formed to protrude toward the formed wall surface. In this case, the support rib 420 may be formed to have a height sufficient to allow the hinge shaft 410 to coincide with the guide groove 321 .

The structure related to the hinge shaft 410 and the support rib 420 is as shown in FIGS. 11 and 12 attached thereto.

Meanwhile, a bent end 430 bent toward the bottom may be formed at the rear end of the cold air cover 400 .

The bent end 430 serves to block the upper side when the cold air cover 400 is rotated and erected vertically. That is, by minimizing the gap between the front surface of the cold air cover 400 and the guide part 320 by the bent end 430, various objects or fingers can be prevented from being caught through the gap.

Of course, the bent end 430 can also serve to prevent the bottom surface from being exposed to the user's gaze when the cold air cover 400 is erected vertically, and prevent bending deformation during the manufacture of the cold air cover 400 . It can also play a role for reinforcing strength.

Next, the refrigerator according to the embodiment of the present invention includes a limiting unit 500 .

Considering that the hinge shaft 410 provided in the cold air cover 400 is formed to be round, and the hinge groove 322 formed in the guide part 320 is also formed to be round, the hinge shaft 410 is the hinge groove ( 322), when the cold air cover 400 is rotated in excess of the vertical state can be made.

In consideration of this, in the embodiment of the present invention, by providing the limiting part 500 in the shelf assembly 300 , it serves to provide interference when the cold air cover 400 rotates, and excessive rotation of the corresponding cold air cover 400 is restricted. it was made to be

That is, the excessive rotation of the cold air cover 400 is prevented due to the interference by the limiting unit 500, so that the cold air cover 400 collides with the storage or the guide unit 320, or another shelf under it. A collision with the assembly 300 can be prevented.

The limiting part 500 may be configured to limit the rotation of the cold air cover 400 so that it can be rotated only to the front position of the guide part 320 . That is, considering that the front surface of the guide part 320 is positioned more forward than the shelf 310, excessive rotation of the cold air cover 400 by allowing the cold air cover 400 to rotate only up to the front surface of the guide part 320. was done to prevent

To this end, the limiting part 500 is formed to protrude downward from the front surface of the guide part 320 toward the bottom as shown in FIGS. 8 and 10 . That is, the limiting part 500 is formed to extend to the bottom of the guide part 320 to limit the rotation angle of the cold air cover 400 . In particular, the limiting unit 500 is positioned as close to the center of rotation of the cold air cover 400 as possible to prevent excessive rotation of the corresponding cold air cover 400 .

On the other hand, when the cold air cover 400 is rotated at an excessively high speed, even if the contact part 600 collides with the limiting part 500 , if the protrusion height of the limiting part 500 is low, the contact part 600 is the It is possible to pass the limiting part 500 .

In consideration of this, the limiting part 500 is most preferably formed to protrude further to the bottom than the bottom surface of the front end of the guide part 320 . This is as shown in the accompanying Figures 13 to 16.

In addition, the front surface of the limiting part 500 is formed to form a plane. That is, since the front surface of the guide part 320 is formed to be round, when the cold air cover 400 is rotated around the hinge groove 322 as a center of rotation, the contact part 600 is prevented from collided with the front surface of the guide part 320, but From the limiting part 500 exceeding the front surface of the guide part 320, it collides with the limiting part 500 so that its rotation can be limited.

Next, the refrigerator according to the embodiment of the present invention includes the contact unit 600 .

The contact part 600 is a configuration provided to prevent excessive rotation of the cold air cover 400 together with the limiting part 500 described above. That is, the contact portion 600 is a portion provided to collide with the limiting portion 500 when the cold air cover 400 is rotated downward while departing from the guide space 301 .

The contact part 600 is formed to protrude from the bottom surface of the cold air cover 400 , and more specifically, the limiting part 500 at a portion facing the limiting part 500 among the bottom surfaces of the cold air cover 400 . ) is formed to protrude toward the

That is, when the cold air cover 400 is drawn out from the guide space 301 and is positioned in a vertically standing state to block the open front of the storage space, the contact portion 600 is located opposite to the limiting portion 500 . It is positioned so that it can come into contact with the limiting part 500 . This is as shown in the accompanying FIGS. 10 and 16 .

In particular, the contact part 600 is formed to extend from the end of one side of the bottom surface of the cold air cover 400 to the support rib 420 . This structure is such that the contact part 600 can also perform a role for reinforcing the strength of the support rib 420, and through this, the support rib 420 is caused by an impact or distortion generated during rotation of the cold air cover 400. ) can be prevented from being damaged.

In this case, side wall portions 440 extending from the contact portion 600 and forming both side wall surfaces of the cold air cover 400 may be further formed at both ends of the cold air cover 400 . That is, due to the effect of reinforcing strength by the side wall portion 440 , torsional deformation during manufacture of the cold air cover 400 may be prevented, and damage to the contact portion 600 may also be prevented.

The structure of the contact part 600 is as shown in FIGS. 11 and 12 attached thereto.

Hereinafter, the operation of the cold air cover 400 of the refrigerator according to the embodiment of the present invention described above will be described in more detail.

First, the cold air cover 400 is accommodated in the guide space (a space between the border frame and the guide part) 301 of the shelf assembly 300 or withdrawn from the guide space 301 according to the user's needs. It is maintained in an upright position.

For example, as shown in FIG. 6 , when a specific storage space between each shelf assembly 300 is not used, the cold air cover 400 is maintained so that the open front of the storage space is opened.

That is, the cold air cover 400 is maintained in a lying state in the guide space 301 , and the hinge shaft 410 formed on the cold air cover 400 is formed in the guide part 320 of the shelf assembly 300 . It is maintained in a state positioned within the guide groove 321 .

Accordingly, the cold air existing in the storage space is in a state in which it can smoothly flow to other spaces in the storage chamber.

On the other hand, when a specific storage space between each shelf assembly 300 is used, the cold air cover 400 is maintained so that the open front of the storage space is closed as shown in FIG. 7 .

That is, the cold air cover 400 is drawn out from the guide space 301 and blocks the open front of the storage space while maintaining a vertically erected state, and the hinge shaft 410 formed in the cold air cover 400 is a guide It remains positioned in the hinge groove 322 formed in the part 320 .

Accordingly, the cold air existing in the storage space only flows in the storage space and is prevented (minimized) from flowing to other spaces in the storage chamber.

Of course, even when the storage space is not used, the cold air cover 400 may be positioned to block the storage space. In this case, the cold air inside the storage space only flows in the storage space and other Flow into space is prevented (minimized).

On the other hand, when the user wants to store the storage in the storage space, he opens the storage space by manipulating the cold air cover 400 that blocks the storage space. At this time, the cold air cover 400 is maintained in a state accommodated in the guide space (301).

And, after storing the stored material in the storage space, the cold air cover 400 is withdrawn from the guide space 301 to close the open front of the storage space.

In the process in which the cold air cover 400 is drawn out in this way, the hinge shaft 410 is moved under the guidance of the guide groove 321 . At this time, since the hinge shaft 410 is formed in a non-circular shape, rotation is prevented while moving along the guide groove 321 . This is as shown in the accompanying Figures 13 and 14.

And, as described above, the hinge shaft 410 reaches the front end of the guide groove 321 while the cold air cover 400 is being drawn out as described above, and when the hinge groove 322 formed in the corresponding portion is located, the hinge The shaft 410 is rotatable within the hinge groove 322 , whereby the cold air cover 400 is rotated based on the hinge shaft 410 by its own weight. This is as shown in the accompanying Figures 15 and 16.

In the process in which the cold air cover 400 is rotated, the contact portion 600 formed on the cold air cover 400 is moved along the round formed on the front surface of the guide portion 320, so that the rotation is not interfered with.

However, in a state in which the cold air cover 400 is vertically erected, the contact portion 600 is in contact with the limiting portion 500 extending from the front lower end of the guide portion 320 .

Accordingly, the cold air cover 400 is not rotated beyond the vertically standing state, and since excessive rotation of the cold air cover 400 is prevented in this way, the cold air cover 400 collides with the stored material stored in the storage space. This can be prevented.

Of course, the phenomenon that the cold air cover 400 is rotated excessively and collides with the guide part 320 can also be prevented.

In particular, when the cold air cover 400 rotates due to its own weight, the support rib 420 on which the hinge shaft 410 is installed may be damaged due to torsion of the hinge shaft 410 . However, since the support rib 420 is extended to the contact portion 600 , its torsion can be prevented, and thus the support rib 420 is prevented from being damaged.

Accordingly, the cold air cover 400 blocks the open front of the storage space and closes it, so that the cold air provided into the storage space is blocked by the cold air cover 400 and flows out to other spaces in the storage room or other storage spaces. Storage is minimized and stored items located in the corresponding storage space are refrigerated (or frozen).

As a result, the refrigerator according to the present invention is provided with the limiting unit 500 and the contact unit 600 to reduce the impact caused by colliding with the shelf assembly 300 or the storage in the storage space when the cold air cover 400 is rotated. can be reduced

In particular, by reducing the above-described impact, not only the impact noise generated by the impact can be reduced, but also the occurrence of damage due to the impact can be prevented.

In addition, in the refrigerator of the present invention, the limiting part 500 is formed to extend to the bottom of the front surface of the guide part 320 , and the contact part 600 is formed to protrude from the bottom surface of the rear side of the cold air cover 400 and the corresponding cold air cover as much as possible. By being positioned adjacent to the center of rotation of the 400, it is possible to prevent excessive rotation of the cold air cover (400).

In addition, in the refrigerator of the present invention, since the limiting part 500 protrudes further to the bottom than the bottom of the guide part 320 , excessive rotation of the cold air cover 400 can be prevented.

In addition, in the refrigerator of the present invention, the contact portion 600 is formed to extend from the side wall portion 440 of the bottom surface of the cold air cover 400 to the support rib 420 , thereby reducing damage to the support rib 420 . .
