Description

Refrigerator {A refrigerator}

The present invention relates to a refrigerator.

Generally, a refrigerator is a device for low temperature storage of food, and is configured to freeze or refrigerate food according to the type of food to be stored.

The inside of the refrigerator is cooled by continuously supplied cold air, and the cold air is continuously generated by the heat exchange action of the refrigerant by a refrigeration cycle undergoing a process of compression-condensation-expansion-evaporation. The cold air supplied to the inside of the refrigerator is evenly transferred to the inside of the refrigerator by convection, so that food in the refrigerator can be stored at a desired temperature.

The refrigerator main body has a rectangular parallelepiped shape with an open front surface, and includes a refrigerating chamber and a freezing chamber inside the main body. The front surface of the main body includes a refrigerator compartment door and a freezer compartment door for selectively shielding the opening.

In addition, the storage space inside the refrigerator is provided with a plurality of drawers, shelves and storage boxes for storing various foods in an optimal state. In addition, a plurality of baskets are provided on the rear of the doors. The storage space inside the refrigerator is partitioned by the shelves, storage boxes, and baskets such that suitable foods can be stored.

At this time, if the width of the storage space is formed wide, the shelf may be provided so that two consecutive in the horizontal direction fall at a predetermined interval. In addition, the shelf may be provided to slide forward so that the withdrawal of food can be made easily. In order to easily adjust the height of the shelf, a locking protrusion may be provided at a rear end of the shelf so as to be fitted to a holder generated on a rear wall of the storage space.

However, the above conventional technologies have the following problems.

The left and right shelves are manufactured through the same process. However, even though the same process is performed, a minute difference in dimensions occurs for each part due to a process error or the like. In addition, a part such as an inner case forming an inner surface of the main body requires a foaming process, but a change in dimensions may occur according to the degree of foaming. In this case, since the shelf is fixed to the holder provided to the inner case, a change in the size of the inner case may affect the position of the shelf.

For the same reason as above, even if the shelves having been subjected to the same process are continuously arranged in the horizontal direction, a step is generated between the shelves. In detail, an upper and lower steps of different heights of the upper surfaces of the shelves provided in the horizontal direction may be generated, and gaps of different front and rear ends of two adjacent surfaces of the shelves may be generated. These front and rear steps may be generated in which the front end of the head is spaced apart from the rear wall of the storage space.

When such a step occurs, it is not easy to store food so as to be supported simultaneously by the left and right shelves. In detail, when the food is placed in the section in which the step occurs, the food may be inclined to one side and the like. In this case, since the load is applied to the shelf on one side more, the shelf may be subjected to deformation such as sagging downward.

In addition, when the shelf is slid, if the step exists, interference occurs between the left and right shelves, there is a problem that the one side of the shelf can not normally slide in and out.

In addition, if the step is present, the aesthetics of the refrigerator is impaired, so that the user's satisfaction with the product is lowered.

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a refrigerator in which generation of a step between neighboring shelves in a horizontal direction is prevented.

In addition, an object of the present invention is to provide a refrigerator in which food stored in the shelf does not tilt.

In addition, an object of the present invention is to provide a refrigerator in which sliding withdrawal of the shelf is smoothly performed.

It is also an object of the present invention to provide a refrigerator in which the shelves are neatly aligned to enhance aesthetics.

The refrigerator according to an embodiment of the present invention for achieving the object as described above is provided with a storage space for storing food at low temperature; A door rotatably provided on the main body to selectively shield the storage space; And a plurality of shelves provided in the storage space and provided in a horizontal direction, and protruding portions protrude from one side of each of the plurality of shelves, and a receiving portion receiving the protrusions is formed on the other side thereof. The projection provided on the shelf is characterized in that it is fitted to the receiving portion of the other adjacent shelf.

According to the refrigerator according to the embodiment of the present invention as described above, there is an advantage that the step between the plurality of shelves provided in the horizontal direction does not occur.

In addition, there is an effect that the food stored in the shelf does not tilt.

In addition, there is an advantage that it is easy to store food because it is not interfered by the shelves located at the side when sliding the draw-out of the shelf.

In addition, since the shelves are neatly aligned, the aesthetics are enhanced and the user's satisfaction with the product is improved.

2 is a perspective view showing a coupling of the shelf and the main body of FIG.

Referring to FIG. 2, the left shelf 15 includes a shelf unit 150 on which food is placed and stored, and a support unit 153 for guiding front and rear sliding of the shelf unit 150.

In detail, the shelf unit 150 includes a shelf surface 152 on which food is placed and an edge portion 151 surrounding the edge of the shelf surface 152. The shelf surface 152 may be formed of transparent glass or the like to facilitate identification of food stored in the refrigerator. Both sides of the edge portion 151 may include a shape bent at least downward for sliding, and may include a stopper (not shown) for limiting sliding.

In addition, the support part 153 has a support frame 154 and the support frame 154 which are provided at lower sides of both ends of the edge part 151 to guide the shelf part 150 to slide forward. Support bar 155 to be connected, provided with a point close to the front end of the support frame 154 includes a locking bar 155 is formed to catch the stopper (not shown) provided on the shelf 150 do.

In detail, the support frame 154 is formed in a plate shape, the coupling portion 157 is formed at the rear end. The coupling part 157 is coupled to the side holder 111 and the center holder 211 provided on the rear wall of the refrigerating chamber 11. In detail, the side holder 111 extends up and down at left and right edges of the rear wall of the refrigerating chamber 11. The center holder 211 is provided in the vertical direction at the center of the cold air duct 21. In the holders 111 and 211, coupling grooves 112 and 212 into which the coupling part 157 is fitted are continuously formed in the vertical direction.

At this time, since the coupling portion 157 of the two shelves should be fitted into the central coupling groove 212, its width may be larger than that of the side coupling groove 112.

On the other hand, the upper portion of the coupling portion 157 is formed in a hook shape, the lower portion is formed in a projection shape. The upper and lower portions of the coupling part 157 are coupled to the coupling grooves 112 and 212, respectively. Therefore, even if the user flips the front end of the left shelf 15 upward, the upper part of the coupling part 157 is provided in a hook shape and thus continues to be caught in the coupling grooves 112 and 212. The combined state of 15) can be maintained.

The first accommodating part 158 is formed at the front end of the right side of the shelf part 150, and the first protrusion 159 is formed at the front end of the left side of the shelf part 150. Details thereof will be described below.

In addition, since the structure of the said right shelf 16 is the same as that of the said left shelf 15, the description of the said left shelf 15 is used, and the detail is abbreviate | omitted.

By the above configuration, the user can freely slide in and out the shelves 15 and 16. In addition, by separating the shelves (15, 16) from the holders (111, 211) and recombining the coupling grooves 112, 212 of the desired height, the height of each of the shelves (15, 16) can be freely adjusted.

3 is a front view of the shelf of FIG. 1, and FIG. 4 is a plan view of the front end of the shelf of FIG. 1.

3 and 4, the left shelf 15 and the right shelf 16 are positioned such that the top and front ends are aligned side by side.

In detail, the first protrusion 159 protrudes from the front end of the left side of the left shelf 15. In this case, the first protrusion 159 may be formed to be inclined or rounded at a predetermined angle. In addition, the first accommodating part 158 is recessed in the front end of the right side of the left shelf 15. Like the first protrusion 159, the first accommodating part 158 is formed to be inclined or rounded at a predetermined angle. The first accommodating part 158 is formed to correspond to the position where the first protrusion 159 is provided. In other words, the position on the right side of the left shelf 15 where the first accommodating portion 158 is provided coincides with the position of the first protrusion 159 on the left side of the left shelf 15.

On the other hand, the right shelf 16 has a second protrusion 169 and the second receiving portion 168 the same structure as the first protrusion 159 and the first receiving portion 158 of the left shelf 15. Is provided. That is, the first protrusion 159, the second protrusion 169, the first accommodating part 158 and the second accommodating part 168 are each formed at the same position.

At this time, the side surfaces provided with the protrusions 159 and 169 and the receiving portions 158 and 168 may be interchanged. That is, the first protrusion 159 may be formed on the right side of the left shelf 15, and the second coupling groove 168 may be formed on the left side of the right shelf 16 to be combined with each other.

Here, the distance between the right side of the left shelf 15 and the left side of the right shelf 16 is shorter than the protruding lengths of the protrusions 159 and 169. Thus, an end portion of the second protrusion 169 is inserted into the first accommodating part 158 by a predetermined depth. That is, when the shelves 15 and 16 having the above configuration are coupled to the coupling grooves 112 and 212 having the same height, the left shelf 15 and the right shelf 16 are positioned side by side.

In this case, the length of the second protrusion 169 may be greater than the sum of the distance between the right side of the left shelf 15 and the left side of the right shelf 16 and the depth of the first accommodating part 158. It may be. In this case, the left shelf 15 and the right shelf 16 are forced to the edges on both sides. That is, the effect of the connection between the left shelf 15 and the right shelf 16 is more robust.

By the shelves 15 and 16 having the above configuration, there is no step difference generated between the shelves 15 and 16.

In detail, since the second protrusion 169 and the first accommodating part 158 are formed and coupled at the same height, a difference in height that may occur between the left shelf 15 and the right shelf 16 is forced. Is corrected. That is, the upper surface of the left shelf 15 and the upper surface of the right shelf 16 are formed horizontally at the same height.

In addition, since the second protrusion 169 and the first accommodating part 158 are formed to be spaced apart from the front ends of the shelves 15 and 16 by the same length, the left shelf 15 and the right shelf ( 16) The position difference between the front end parts that may occur is compulsorily corrected. That is, the front end portions of the left shelf 15 and the right shelf 16 are spaced apart by the same length from the rear wall surface of the refrigerating compartment 11. In other words, the front ends of the left shelf 15 and the right shelf 16 are located on one straight line.

Meanwhile, as described above, the shelves 15 and 16 are provided to slide in and out. In addition, when the shelves 15 and 16 are separated from the holders 111 and 211 to adjust the heights of the shelves 15 and 16, the shelves 15 and 16 are upper portions of the coupling part 157. The shear should be flipped upward with the hook engaged. That is, the second protrusion 169 should be separated from the first accommodating part 158 by the draw-out operation or the upward movement.

To this end, the second protrusion 169 and the first accommodation portion 158 is formed to be inclined or rounded at a predetermined angle as described above. In detail, the second protrusion 169 may protrude to be inclined in the front-rear direction and the vertical direction, and the first accommodating part 158 may be recessed to correspond thereto. Alternatively, the second protrusion 169 may be rounded in a circular shape, and the first accommodating part 158 may be recessed to correspond thereto. By the above configuration, when a user applies a force to move the shelves 15 and 16, the inclined surface or the rounded portion of the second protrusion 169 is along the first accommodating part 158. It is moved out of the receiving portion 158.

Accordingly, the left shelf 15 and the right shelf 16 are normally connected without a step by a combination of the second protrusion 169 and the first accommodating part 158 and sliding one shelf. When detaching one shelf for height adjustment, it is easily removed. That is, one shelf can be independently slid out or detached.

In addition, since the upper surface of the left shelf 15 and the right shelf 16 is provided horizontally at the same height, there is an effect that the food stored is not inclined. Therefore, even if food is placed in the space between the shelves 15 and 16, the load is not concentrated on one shelf, thereby preventing deformation and increasing the service life of the shelves 15 and 16.

In addition, since no step is generated between the left shelf 15 and the right shelf 16, the shelves 15 and 16 are smoothly slid.

In addition, since the shelves 15 and 16 are neatly aligned, the aesthetics are enhanced, thereby improving the user's satisfaction with the product.

On the other hand, the left shelf 15 and the right shelf 16 is provided to be detachable, since both shelves are the same structure, the left and right of the shelf can be changed according to the user's use. However, in this case, since the first protrusion 159 and the second coupling groove 158 are coupled, the same effects as those described above can be obtained.

Hereinafter, a refrigerator according to a second embodiment of the present invention will be described with reference to the drawings. However, since the second embodiment has a difference in the accommodating portion as compared with the first embodiment, the difference is mainly described, and the description of the first embodiment is used for the same parts.

5 is a perspective view illustrating a front end of a shelf of a refrigerator according to a second embodiment of the present invention.

Referring to FIG. 5, the shelf 300 includes a shelf surface 302 on which food is placed and an edge portion 301 that surrounds the edge of the shelf surface 302.

In addition, an accommodating part 303 is formed at the front end of the left side of the edge part 301. In detail, the receiving portion 303 is formed with a plurality of projections radially. No member is provided in the central portion, or is formed to be recessed to a predetermined depth so that the protrusions of the other shelf can be fitted.

The protrusion of the other shelf is moved in the front-rear direction with respect to the receiving part 303 as the other shelf is slid, and is moved in the vertical direction according to the detachment of the other shelf. Therefore, no projection is formed in the front-back direction or the vertical direction of the accommodation portion 303, so that the projection of the other shelf can be smoothly moved. That is, the protrusions of the accommodation portion 303 are provided to be spaced apart by a predetermined interval in the front-back direction or the vertical direction. At this time, the protrusions forming the accommodation portion 303 is the height of the protrusion protruding toward the edge from the inner end so that the fitting state of the protrusions of the other shelf is maintained stably, and the protrusions of the other shelf can be smoothly escaped. It can be formed to increase.

According to the refrigerator according to the second embodiment of the present invention as described above, even if protrusions are formed on both sides of the shelf, a step between the left and right shelves does not occur, so that the same effect as in the first embodiment can be obtained. There is an advantage.

The scope of the present invention is not limited to the above-described embodiments, and the embodiments may be changed, added, or deleted within the scope of the spirit of the present invention.
