DEVICE FOR LEVEL ADJUSTMENT OF REAR SIDE OF ELECTRICAL MACHINE}

The present invention relates to a rear horizontal control device for household goods, and more particularly, to a rear horizontal control device for household goods designed to perform the height adjustment of the rear end of the household goods at the front end of the household goods.

Household items such as refrigerators, washing machines and air conditioners need to be leveled when installed. Therefore, when the floor is not flat, it was conventionally fixed by inserting a structure such as paper, board or brick on the installation surface of the household goods. However, since this method is not easy to adjust the horizontal and the work is cumbersome, the household goods are often released with a height adjustable structure installed.

Apparatuses for adjusting the level of household goods have been developed in various forms, starting with a simple method of screwing a support to the bottom of the household goods, and in recent years, more complicated and more convenient products have appeared.

Korean Patent Registration No. 150088 filed on December 8, 1995, under the heading 'Horizontal adjusting device of air conditioner outdoor unit', installs the rotating body by operating the adjusting member by gear-coupling a separate adjusting member with the rotating body. A technique for adjusting the height of an outdoor unit of an air conditioner by performing a spiral motion with a sphere is disclosed.

These techniques, however, use only the front of the household goods to perform the leveling work, the level of the rear of the household goods is almost difficult to adjust the situation. In fact, the household goods are installed to be attached to the wall or side-by-side with other household goods, it was easy to control the front part of the household goods, but it was almost impossible to control the rear part.

However, in general, since the adjustment of the rear part is also necessary in order for the household goods to be perfectly level, the conventional technique of adjusting only the front part actually performs only half the horizontal adjustment function.

The present invention was devised to solve the above problems, and an object of the present invention is to provide a rear horizontal control device for household goods, which is designed to perform horizontal adjustment on the rear part of household goods.

The following drawings attached to this specification are illustrative of the preferred embodiments of the present invention, and together with the detailed description of the present invention to serve to further understand the technical spirit of the present invention, the present invention is a matter described in such drawings It should not be construed as limited to.
