Hereinafter, an embodiment of a refrigerator according to the present invention having the configuration as described above will be described in detail with reference to the accompanying drawings.

Figure 2 is a partial perspective view showing the outer surface of the first embodiment of the refrigerator according to the present invention, as shown in the figure, the main body 100 of the refrigerator is formed in a substantially rectangular parallelepiped shape, the inside of the main body 100 The storage space opened forward is formed.

The inside of the main body 100, that is, the inside of the storage space having a front opening, is divided into left and right sides to form a refrigerating compartment and a freezing compartment, respectively. The refrigerating compartment and the freezing compartment are selectively shielded by the door 120, respectively.

The door 120 is rotatably mounted from the front side of the main body 100 to the left and right sides, and is configured to selectively shield the refrigerating chamber and the freezing chamber by rotation.

On the other hand, the bottom surface of the main body 100 is provided with a plurality of roller assembly 200. The roller assembly 200 is to be able to move the relatively heavy refrigerator body 100 more easily and stably, it will be preferable to be mounted on the four corners of the lower surface of the body (100).

Looking at the configuration of the roller assembly 200 in more detail through FIG. 3 as follows.

3 is an exploded perspective view illustrating a coupling relationship between a roller assembly and a horizontal control mechanism, which are main components of a refrigerator according to a first embodiment of the present invention. As shown in the drawing, the roller assembly 200 includes a roller 220. And a rotation shaft 240 and a bracket 260.

The roller 220 is formed in a circular wheel shape having a predetermined size as in general wheels to allow the main body 100 to move by rolling in contact with the bottom surface.

On the other hand, the roller 220 is substantially penetrated laterally by the rotation shaft 240 is formed in a round bar shape. Therefore, the rotating shaft 240 is the center of rotation of the roller 220, is mounted to the bracket 260 to be described in detail below, as well as formed to have a predetermined length to be in contact with the horizontal adjustment mechanism (A). do.

The bracket 260 is mounted so that the roller 220 is rotatable, and the cross section of the bracket 260 is formed in a substantially "∩" shape to surround the roller 220 from above. Therefore, the roller 220 is accommodated between the brackets 260, and the rotating shaft 240 penetrating the rollers 220 is mounted through the long holes 262 on both sides of the bracket 260.

The long hole 262 is formed in approximately the center of the left and right sides of the bracket 260, is formed to be perforated in the bracket 260 in a corresponding size so that the rotating shaft 240 can penetrate, and long in the vertical direction Is formed.

Therefore, the rotating shaft 240 mounted through the long hole 262 is movable up and down along the long hole 262, and the overall height of the roller assembly 200 is moved by the movement of the rotating shaft 240. Can be adjusted.

As a result, the roller 220 is rotatably mounted inside the bracket 260, and both sides of the rotation shaft 240 penetrating the bracket 260 may protrude somewhat to the left and right sides of the bracket 260. It can be formed in any length.

On the other hand, the left and right sides of the bracket 260 is provided with a horizontal adjustment mechanism (A). The horizontal adjustment mechanism (A) is to adjust the height of the roller assembly 200, more specifically, the rotation shaft (depending on the load of the main body 100 and the state of the bottom surface on which the main body 100 is installed) By adjusting the height of the 240, the height of the roller assembly 200 may be adjusted to maintain the main body 100 in a horizontal state.

To this end, the horizontal adjustment mechanism (A) is composed of a spring 300 having an elasticity. And, the upper end of the spring 300 is fixed to one side of the upper portion of the bracket 260, or fixed to one side of the lower surface of the main body 100, the lower end of the spring 300 to the side of the bracket 260 It comes into contact with the protruding rotation shaft 240.

The lower end of the spring 300 in contact with the rotary shaft 240 is formed to correspond to the outer peripheral surface shape of the spring 300 to reliably press the rotary shaft 240 from above to accommodate the upper portion of the rotary shaft 240 Support member 320 may be further provided.

On the other hand, the springs 300 respectively provided on one side of the roller assembly 200 mounted on the four corners of the lower surface of the main body 100 are all different in the spring constant according to the position of the roller assembly 200.

This is due to the difference in load according to the location of the refrigerator. Generally, since the second half of the refrigerator including the compressor, the condenser, the evaporator, etc. constituting the refrigeration cycle is heavier than the first half of the refrigerator, the roller assembly for supporting the refrigerator ( In order to adjust the height of the horizontal 200, the spring constant should be different according to the position of the roller assembly 200.

That is, the spring constant of the spring 300 provided in the roller assembly 200 mounted at the edge of the bottom surface of the main body 100 is relatively mounted to the edge of the front end of the bottom surface of the main body 100. It will be preferable to be formed to have a larger value than the spring constant of the spring 300 provided in the (200).

On the other hand, above the bracket 260 is further provided with a mounting portion 264 protruding upward so that the bracket 260 can be mounted to the main body 100. The mounting portion 264 extends upwardly to be inserted into a mounting hole (not shown) formed to correspond to the edge of the lower surface of the main body 100, and has a round bar shape so that the bracket 260 may be rotatably mounted. It will be preferable to form.

Therefore, the roller assembly 200 can be freely rotated about the mounting portion 264 to easily change the direction of the main body 100 during transportation.

Of course, the bracket 260 may be fixedly mounted on the lower surface of the main body 100 by welding or screwing, and may be integrally formed with the lower surface of the refrigerator main body 100 as necessary.

Hereinafter, the operation of the roller assembly according to the first embodiment of the refrigerator according to the present invention having the configuration as described above will be described with reference to the accompanying drawings.

4A and 4B are schematic views schematically showing the action of a horizontal adjustment mechanism, which is a main component of the first embodiment of the refrigerator according to the present invention. As shown in these drawings, first, the main body 100 of the refrigerator for installation of the refrigerator is shown. ) Should be transported to the installation site.

When transporting the refrigerator main body 100, the roller 220 is moved while moving in rolling motion, and when it reaches a position for installation of the refrigerator, the operator adjusts the position of the refrigerator main body 100 and the refrigerator The horizontal state of the main body 100 is confirmed.

At this time, the height of the roller assembly 200 is naturally adjusted according to the state of the bottom surface on which the refrigerator main body 100 is installed, which is naturally made by the load of the refrigerator main body 100.

Looking at this in more detail through the drawings, Figure 4a shows the state of the roller assembly 200 when the height of the bottom surface is relatively low compared to other locations.

When the height of the bottom surface is relatively low compared to other positions in the place where the refrigerator main body 100 is installed, the roller assembly 200 at the corresponding position is relative to the roller assembly 200 mounted at another position. Less load.

Therefore, since a relatively small load is also transmitted to the roller 220 in contact with the bottom surface, the spring 300 in contact with the rotation shaft 240 is relatively tensioned to push the rotation shaft 240 downward so that the rotation shaft ( 240 is adjusted to be positioned below the long hole 262 of the bracket 260.

As a result, the roller 220 is in contact with the bottom surface, and the overall height h of the roller assembly 200 at this time is higher than that of the roller assembly 200 in a relatively different position.

On the other hand, Figure 4b shows the state of the roller assembly when the height of the bottom surface is relatively high compared to other positions.

When the height of the bottom surface is relatively high compared to other positions at the place where the refrigerator main body 100 is installed, the roller assembly 200 at a position corresponding thereto is relatively relative to the roller assembly 200 mounted at another position. You will be heavily loaded.

Therefore, since a relatively large load is also transmitted to the roller 220 in contact with the bottom surface, the spring 300 in contact with the rotation shaft 240 is relatively compressed, and the rotation shaft is compressed by the spring 300. The position in contact with the 240 is moved upwards so that the rotary shaft 240 is positioned above the long hole 262 of the bracket 260.

As a result, the roller 220 is in contact with the bottom surface, and the overall height h 'of the roller assembly 200 at this time is lower than that of the roller assembly 200 at a relatively different position.

In this way, the height (h, h ') of the roller assembly 200 is naturally adjusted according to the state of the bottom surface on which the main body 100 is installed so that the refrigerator main body 100 can maintain a horizontal state as a whole.

Meanwhile, the refrigerator according to the present invention may be configured with various other embodiments in addition to the above-described first embodiment. Hereinafter, a refrigerator according to the second embodiment of the present invention will be described with reference to the accompanying drawings.

Since the overall configuration of the refrigerator main body 100 and the overall configuration of the roller assembly 200 are the same as those of the first embodiment described above, the detailed description will be omitted, and the same configuration will be described using the same reference numerals. do.

Figure 5 is a partial perspective view showing the outer surface of the second embodiment of the refrigerator according to the present invention, Figure 6 is an exploded perspective view showing a coupling relationship between the roller assembly and the horizontal adjustment mechanism of the main configuration of the second embodiment of the refrigerator according to the present invention to be.

As shown in these figures, the main body 100 of the refrigerator is formed in a rectangular parallelepiped shape, and the inside of the main body 100 is divided into left and right to form a refrigerating chamber and a freezing chamber. In addition, the refrigerating compartment and the freezing compartment are selectively shielded by doors 120 that open and close left and right, respectively.

In addition, the lower surface of the refrigerator main body 100 is provided with a roller assembly 200 to facilitate the movement of the main body 100. The roller assembly 200 is formed at each corner of the lower surface of the main body 100 to facilitate the horizontal movement of the main body 100 and to facilitate the movement of the main body 100.

The roller assembly 200, as in the first embodiment described above, the roller 220 and the rolling shaft 240 and the long hole 262 through which the roller 220 and the rolling motion in contact with the ground is formed, the rotating shaft By allowing the 240 to penetrate, the bracket 220 is configured to support the mounting of the roller 220.

On the other hand, both sides of the bracket 260 is provided with a horizontal adjustment mechanism (A). The horizontal adjustment mechanism (A) is to adjust the height of the roller assembly 200 according to the user's operation so that the main body 100 to maintain the horizontal when the refrigerator is installed on the upper side of the bracket 260 It is composed of a control cam 400 is mounted to be rotatable.

The adjustment cam 400 is formed in the same shape as the general cam is formed with a different radius at the center of rotation, it is mounted on the upper side of the bracket 260 corresponding to the vertical upward of the rotation shaft 240. At this time, the adjustment cam 400 is penetrated by the screw 420, the screw 420 is fastened to the bracket 260.

And, the adjustment cam 400 is mounted to the bracket 260 to be rotatable together in accordance with the rotation of the screw 420, if necessary, one side of the lower surface of the main body 100 instead of the bracket 260 It may be mounted on.

On the other hand, the adjustment cam 400 is always mounted so that the outer circumferential surface is in contact with the outer surface of the rotary shaft 240 is formed so as to press the rotary shaft 240 from above to support it. At this time, since the distance from the center of rotation to the outer peripheral surface of the adjustment cam 400 is formed differently, the rotating shaft 240 contacting the control cam 400 can be moved up and down according to the rotation of the adjustment cam 400.

By moving the rotary shaft 240 up and down is possible to adjust the operating height of the roller 220 in contact with the ground, thereby enabling the adjustment of the overall height of the roller assembly 200.

On the other hand, the roller assembly 200 may be mounted only on both sides of the front edge of the lower surface of the main body 100, if necessary, in this case, the rear end of the lower surface of the main body 100 is a roller capable of rolling motion only It would be desirable to be equipped.

Hereinafter, the operation of the roller assembly according to the second embodiment of the refrigerator according to the present invention having the configuration as described above will be described with reference to the accompanying drawings.

7A and 7B are schematic views schematically showing the operation of a horizontal adjustment mechanism, which is a main component of a second embodiment of the refrigerator according to the present invention. As shown in these drawings, first, the main body 100 of the refrigerator for installation of the refrigerator is shown. ) Should be transported to the installation site.

When transporting the refrigerator main body 100, the roller 220 is moved while moving in rolling motion, and when it reaches a position for installation of the refrigerator, the operator adjusts the position of the refrigerator main body 100 and the refrigerator The horizontal state of the main body 100 is confirmed.

In this case, when the bottom surface on which the main body 100 is installed is not in a horizontal state, the operator operates the horizontal adjusting mechanism A to adjust the height of the roller assembly 200 to maintain the main body 100 in a horizontal state. To maintain.

Looking at this in more detail through the drawings, Figure 7a shows the state of the roller assembly when the height of the bottom surface is relatively low compared to other positions.

When the height of the bottom surface is relatively low in other places where the refrigerator main body 100 is installed, the height of the roller assembly 200 is relatively higher than that of the roller assembly 200 mounted at another position. Adjust to be high.

To this end, the screw 420 penetrates the adjusting cam 400 so that the outer circumferential surface of the long distance between the center of rotation of the adjusting cam 400 and the outer circumferential surface is in contact with the outer circumferential surface of the rotating shaft 240. The cam 400 is rotated.

When the adjustment cam 400 is rotated, the distance between the rotation center of the adjustment cam 400 and the rotation shaft 240 is far, and thus the rotation shaft 240 in contact with the control cam 400 is The lower hole 262 is located below.

When the rotating shaft 240 is positioned below the long hole 262, the roller 220 is also moved downward and in contact with the ground in this state, so that the height (h) of the roller assembly 200 as a whole Relatively higher.

On the other hand, Figure 7b shows the state of the roller assembly when the height of the bottom surface is relatively high compared to other positions.

When the height of the bottom surface is relatively high in other places where the refrigerator main body 100 is installed, the height of the roller assembly 200 is relatively lower than that of the roller assembly 200 mounted at another position. To be adjusted.

To this end, by adjusting the screw 420 passing through the adjustment cam 400, the adjustment is made so that the outer circumferential surface of the portion having a short distance between the center of rotation of the adjustment cam 400 and the outer circumferential surface is in contact with the outer circumferential surface of the rotation shaft 240. The cam 400 is rotated.

When the adjustment cam 400 is rotated, the distance between the rotation center of the adjustment cam 400 and the rotation shaft 240 is close, and thus the rotation shaft 240 in contact with the adjustment cam 400 is It is located above the long hole 262.

When the rotating shaft 240 is located above the long hole 262, the roller 220 is also moved upwards and in contact with the ground in this state, the height (h ') of the roller assembly 200 as a whole Becomes relatively lower.

In this way, the height of the roller assembly 200 is rotated by rotating the control cam 400 so that the main body 100 is in a horizontal state according to the height of the bottom surface on which the main body 100 of the refrigerator is installed. h, h ') to maintain the main body 100 in a horizontal state.

The scope of the present invention is not limited to the above embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

In the refrigerator according to the present invention as described above in detail has the following effects.

First, the roller assembly is provided with a horizontal adjustment mechanism for adjusting the height of the roller drive it is possible to adjust the height of the roller assembly. Therefore, the mounting of the roller assembly facilitates the movement of the main body, as well as to adjust the horizontal level of the main body.

As a result, the overall configuration is concise, so that the manufacturing cost can be reduced and the labor cost can be reduced, thereby improving productivity.

Second, when a spring is employed as the horizontal adjustment mechanism for adjusting the height of the roller assembly, the height of the roller assembly can be automatically adjusted by the load of the main body and the elasticity of the spring.

Therefore, the horizontal adjustment of the refrigerator can be made naturally without a separate operation, thereby making the installation easier.

In addition, since the horizontal leveling is naturally performed even in the second half of the refrigerator, which is difficult to adjust the horizontal level, the overall leveling performance of the refrigerator main body may be improved.

Third, when the adjustment cam is employed as a horizontal adjustment mechanism for adjusting the height of the roller assembly to adjust the height of the roller assembly by directly rotating the cam by the operation of the screw.

Therefore, it is possible to operate while watching the rotation of the roller assembly directly, it is possible to easily measure the height change of the roller assembly and accordingly the fine adjustment is possible by only one rotation or 1/2 rotation of the adjustment cam is a horizontal adjustment work The effect which becomes easier can be expected.
