Benefits of technology

[0014] One aspect of the invention is to provide a refrigerator, in which one moving member is installed at one of front and rear parts of a main body, thereby minimizing a difference of heights of doors, and easily adjusting the difference of heights of the doors when the refrigerator is installed.
[0015] Another aspect of the invention is to provide a refrigerator, which reduces the number of contact points between a main body thereof and a floor of an indoor space, thereby being easily moved and installed.

Problems solved by technology

Since the four wheels are installed at the four corners of the bottom surface of the refrigerator, the above conventional refrigerator cannot be smoothly moved, and increases the probability of damaging a floor of an indoor space, and after movement, it is difficult to level the refrigerator.
That is, the conventional refrigerator is moved while supported at four points on the floor of the indoor space by the four wheels, thus requiring a large force for movement.
Further, the conventional refrigerator requires excessive support points on the floor of the indoor space, thus increasing the probability of damaging the floor of the indoor space during movement.
Since the refrigerator must be leveled via the two wheels installed at both front corners of the bottom surface thereof when the refrigerator is located at a desired position, it is difficult to level the refrigerator and it takes considerable time to level the refrigerator.
When the floor of the indoor space is not even, it is more difficult to move and level the refrigerator.
Since a refrigerator having a large volume has a large weight, it is more difficult to move the refrigerator while supported at four points in the same manner as the above conventional refrigerator.
Further, in this case, since it is difficult to precisely level the refrigerator having the large volume, freezing and chilling chamber doors of the refrigerator sag, thereby decreasing sealing force of the freezing and chilling chamber doors and generating noise when the freezing and chilling chamber doors are opened and closed.

first embodiment

[0029]FIG. 1 is a schematic exploded perspective view illustrating a bottom surface of a refrigerator in accordance with the present invention.

[0030] As shown in FIG. 1, the refrigerator 1 in accordance with the first embodiment of the present invention includes a main body 10 provided with an opened front surface and including a freezing chamber (not shown) and a chilling chamber (not shown) for containing foods therein, a freezing chamber door 11 and a chilling chamber door 12 installed on the opened front surface of the main body 10 for respectively opening and closing the freezing chamber and the chilling chamber, and a rolling unit 20 and a plurality of height adjustable legs 30 installed on a bottom surface 10a of the main body 10.

[0031] The freezing chamber door 11 is hinged to one side end of the main body 10 by a hinge member 13 such that the freezing chamber door 11 can be rotated, and the chilling chamber door 12 is hinged to the other side end of the main body 10 by a h...

second embodiment

[0047] That is, in the refrigerator 1 of the second embodiment, the rolling unit 20 includes one front wheel 20a, having a ball structure, installed at the approximately central point of the front part of the bottom surface 10a of the main body 10, and a pair of rear wheels 20b, each having a ball structure, installed at both corners of the rear part of the bottom surface 10a of the main body 10.

[0048] Accordingly, the refrigerator 1 of the second embodiment can be rapidly moved rectilinearly or curved by a small force, compared to the refrigerator 1 of the first embodiment in which the front and rear wheels 20a and 20b of the rolling unit 20 are respectively made of rollers.

[0049]FIG. 5 is a schematic exploded perspective view illustrating a bottom surface of a refrigerator in accordance with a third embodiment of the present invention. As shown in FIG. 5, the refrigerator 1 of the third embodiment is the same as that of the first embodiment except that positions of the front and ...

third embodiment

[0050] That is, in the refrigerator 1 of the third embodiment, the rolling unit 20 includes a pair of front wheels 20a installed at both corners of the front part of the bottom surface 10a of the main body 10 and serving as one moving member, and one rear wheel 20b installed at the approximately central point of the rear part of the bottom surface 10a and serving as other moving members.

[0051] Accordingly, the refrigerator 1 of the third embodiment is moved while supported at three points on the floor 5 of the indoor space in the same manner as those of the first and second embodiments, thus being easily and rapidly moved.

[0052] The above-described embodiments of the present invention provide a refrigerator, which is moved while supported at three points, thus being easily and rapidly moved compared to conventional refrigerators. Further, the refrigerator is easily and rapidly leveled when the refrigerator is located at a desired position, thus being rapidly handled. Moreover, sinc...

Abstract

A refrigerator, which minimizes and easily adjusts a difference of heights of doors, and reduces the number of contact points with a floor of an indoor space, thereby being easily moved and installed. A pair of rear wheels are installed at both corners of a rear part of a bottom surface of a main body and one front wheel is installed at an approximately central point of a front part of the bottom surface so that the refrigerator is moved while the refrigerator is supported at three points. Height adjustable legs, heights of which are adjusted, are installed at both corners of the front part of the bottom surface, and the height adjustable legs together with the front and rear wheels allow the refrigerator to be leveled.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of Korean Patent Application No. 2004-68206, filed Aug. 28, 2004, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a refrigerator, and more particularly, to a refrigerator which is smoothly moved and is rapidly leveled. [0004] 2. Description of Related Art [0005] Generally, a refrigerator serves to store various foods in a fresh state for a long time by supplying cold air, generated from an evaporator, to storage chambers, such as a chilling chamber and a freezing chamber. Recently, refrigerators having a large volume for storing a large quantity of foods have been manufactured and sold. [0006] Such a refrigerator having a large volume includes a main body, the front surface of which is opened, a chilling chamber and a freezing chamber divided by a...
