The present invention relates to a leveling device for a refrigerator, and to a leveling device for a refrigerator configured to automatically detect a tilt of the refrigerator and adjust the height of the adjustment group based on a detected signal value.

In general, the lower portion of the refrigerator is provided with a simple horizontal adjustment device that can adjust the horizontal, mainly to adjust the predetermined height by the manual adjustment screw bolts on both sides of the front.

The leveling device using the adjustment bolt is a lot of weight of the refrigerator because it is difficult to adjust by hand every day, there is also a risk of inadvertent hand injuries.

In addition, it is difficult to maintain the level of the refrigerator precisely by adjusting the adjustment bolts. If the level is not correct, it is inconvenient to use paper or plywood on the rear casters, and to re-adjust during installation. There is a difficulty.

As such, when the level of the refrigerator is not properly made, the door of the refrigerator may sag as well as the cap of the refrigerator is twisted.

Therefore, the present invention has been made to solve the above problems, the purpose of the horizontal adjustment of the refrigerator so that the horizontal adjustment of the refrigerator is easy and at the same time the horizontal detection unit is automatically made without regard to the installation place In providing a device.

A feature of the present invention for achieving the above object is, in the refrigerator having a power supply for receiving commercial power required for driving, by receiving the power output from the power supply to detect the inclination of the refrigerator during installation of the control unit A horizontal detection unit for transmitting a horizontal control unit, a horizontal adjustment motor driver for driving a horizontal control motor according to a control signal of the controller according to the inclination of the refrigerator detected by the horizontal detection unit, and a horizontal adjustment unit for horizontally adjusting the inclination of the refrigerator according to the driving of the horizontal motor It is configured to include a control unit.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a block diagram of the main part of the horizontal control device of the refrigerator according to the present invention, Figure 2 is a main part installation state diagram according to the present invention, Figure 3 is a detailed view showing the combined state of the horizontal control motor and the horizontal control unit of FIG. to be.

Referring to FIG. 1, the leveling device of the refrigerator according to the present invention first, the user is installed in a convenient place to use the refrigerator, and then the power supply unit 10 receives the commercial power required for driving the refrigerator, and the power supply unit Control unit 11 for controlling the entire system of the refrigerator by receiving the power output from the (10), the control signal of the control unit 11 is applied to detect the inclination of the refrigerator during installation of the refrigerator and transmits to the control unit (11) The horizontal control unit 12, the horizontal control motor driving unit 13 for driving the horizontal control motor 14 in response to the control signal of the control unit 11 in accordance with the inclination of the refrigerator detected by the horizontal detection unit 12, the horizontal control motor It is configured to include a horizontal control unit 15 for horizontally adjusting the inclination of the refrigerator according to the driving of (14).

That is, as shown in FIG. 2, the leveling device of the refrigerator includes the inside of the refrigerator 16 according to the inclination of the refrigerator detected by the horizontal detectors 12 of the refrigerator installed at both front sides of the bottom surface of the refrigerator 16. Under the control of the control unit 11 disposed on one side, the adjustment group 27 of the horizontal control unit 15 moves in accordance with the driving of the horizontal control motor 14 to level the refrigerator.

Referring to Figure 3 described in detail the horizontal adjustment unit as follows.

Referring to FIG. 3, the horizontal adjustment motor 14, in which the output shaft 21a rotates forward and backward by the inclination of the refrigerator detected by the control unit 11, is fixed to the plate 22 by bolts 23. The drive gear 24 is affixed to the output shaft 21a of the motor 14, and the driven gear 25 meshing with the drive gear 24 is fixed to one side of the front surface of the plate 22. At the same time, the screw hole 25a of the driven gear 25 is screwed to the screw shaft 27a of the adjustment group 27.

The through holes 22a and 22b of the plate 22 are holes formed by the screw shafts 27a of the drive gear 24 and the adjustment group 27 to facilitate assembly.

In order to horizontally adjust the horizontal control unit 15 configured as described above (installed on both sides, but for convenience of description, one horizontal control device will be described). First, the horizontal control motor 14 according to the control signal of the control unit 11. When driven), the output shaft 21a of the horizontal control motor 14 is rotated forward and backward, and at the same time, the driven gear 25 engaged with the drive gear 24 rotates inside the gear cover 26.

Accordingly, the screw shaft 27a of the adjustment group 27 screwed to the screw hole 25a of the driven gear 25 is raised or lowered along the screw hole 25a.

Therefore, precisely controlling the amount of rotation of the horizontal control motor 14, the horizontal adjustment of the refrigerator is made simply.

4A and 4B show the horizontal detection unit applied to the present invention in another form, and the electrode adjusting plate 31 is mounted on the upper part of the case 30 in which the conducting plate 30a is attached to the inner bottom surface. The cover 32 which fixes the adjustment plate 31 to the case 30 is comprised, The cavity terminal 33 is fixed to the center of the said electrode adjustment plate 31, and the terminal 34 is surrounded by this cavity terminal 33. As shown in FIG. , 35, 36, 37 are fixedly disposed, and the joint terminal 33 is freely moved to the upper surface of the conduction plate 30a of the case 30 according to the inclination of the case 30. There is a mercury sphere 38 which alternatively energizes any one of 36 and 37.

The horizontal detection unit configured as described above, each terminal (34, 35, 36, 37) is connected to the control unit 11 is installed in the center of the refrigerator, but preferably installed on the bottom bottom bottom.

That is, as the refrigerator is inclined, the mercury bulb 38 inside the case 30 moves to contact the common terminal 33 with any one of the terminals 34, 35, 36, and 37. The control signal is transmitted to the side, and the control unit 11 controls the horizontal control motor 14 to adjust the adjustment group 27 to adjust the level of the refrigerator.

5A and 5B are a perspective view and an enlarged cross-sectional view showing another embodiment of the horizontal adjustment unit of FIG. 2, and the adjustment feet provided at each end of the cross-shaped support base 40 supporting the refrigerator 16 downwardly. As an embodiment of the method for controlling the horizontal control motor 14 to adjust the height of the (27), each of the micro switch 42 is located inside the support base 40, the micro switch 42 is a refrigerator It is to be switched on by the ball 43 moving in the ball guide groove 41 in accordance with the inclination of, the upper portion of the micro switch 42 in the recess 41a to prevent malfunction due to unnecessary vibration of the refrigerator, etc. Is formed.

That is, as the refrigerator is inclined, the ball 43 moves in the ball guide groove 41 in the direction in which the refrigerator is inclined to operate the micro switch 42, and the micro switch 42 is the tilting side horizontal adjustment motor 14. The adjustment group 27 connected with the rotation is to adjust the horizontal.
