DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for leveling a washing machine, and more particularly, to an improved structure of an apparatus for adjusting the level and height of a washing machine when a product is installed.

[0002]

2. Description of the Related Art In general, a washing machine uses clothes, bedding, etc. by utilizing a mild action of a detergent, a friction action of a water flow caused by rotation of a washing wing, and an impact action applied to laundry by the washing wing. This is a household electrical appliance that removes various contaminants that were associated with it.Sensors detect the amount and type of laundry and automatically set the washing method, and the washing water reaches an appropriate water level based on the amount and type of laundry. After water is supplied, washing is performed under the control of the microcomputer. A lower portion of the washing machine having such a function is provided with a height adjusting means for adjusting the height when the product is installed at the installation location so as to adjust the level of the front-back method and the left-right method of the device. In most cases, the bottom surface where the washing machine is installed is not flat due to drainage, so the height adjustment means is used to maintain the equality of the washing machine and to be generated due to the uneven load of the laundry during washing and spin-drying. The vibration of the washing tub and the outer tub can be reduced.

An example of a height adjusting device provided in a conventional washing machine will be described with reference to FIG.

The existing washing machines include a type having a silent base and a type having no silent base, and the leg mounting structure is applied to both types having a silent base and those having no silent base. Here, a type of washing machine having a silent base will be described.

As shown in FIG. 1, a conventional washing machine includes a spindle leg 40a screwed to a front face F of a silent base 2a fixed to the bottom of an out case 1, and a screw thread on a rear face R of the silent base 2a. The height and the level are adjusted by a rubber toe 5 to be connected.

The spindle leg 40a is mounted on both sides of the front surface of the silent base 2a forming the bottom of the washing machine, and includes a screw portion 400 having a square screw thread formed on the outer peripheral surface, and one of the screw portions 400. And a head portion 401 integrally formed at the side end and in contact with the bottom surface on which the washing machine is provided. This supports the load of the washing machine and adjusts the height. At this time, the screw portion 400 of the spindle leg 40a is screw-coupled to a screw groove (not shown) formed on a corresponding portion of the bottom surface of the silent base 2a, and is rotated by an external force to adjust its height. It has become so. That is, a thread groove is formed on the bottom surface of the silent base 2a, and by rotating the spindle leg 40a in a state where the spindle leg 40a is screw-coupled to the thread groove, the protrusion height of the spindle leg 40a with respect to the base is reduced. Adjust to adjust the horizontal.

On the other hand, a rubber toe 5 made of a rubber material is fixed to both sides of the rear surface R of the base. As shown in the figure, the rubber toe 5 has a through hole 5 penetrating the center thereof.
Since the screw S is fastened and fixed to the bottom surface of the silent base 2a via the pin 00, the height cannot be adjusted.

As described above, the conventional leveling device of a washing machine has a pair of spindle legs 40a provided on both front sides of the base so as to be adjustable in height, and is fixed to both rear sides of the base so that the height cannot be adjusted. And a pair of rubber toes 5. Such a leveling device is already mounted on the silent base 2a at the stage of loading and transporting the product before the product is installed on the bottom surface of the washing machine.

Such a conventional washing machine has a problem in that the height of the product is high, so that a large amount of packaging material is required at the time of packaging the product, and the loading space is increased when the packaged product 7a is loaded. there were. That is, since the height hc of one product is high, a large amount of packaging material is required at the time of packaging, and as shown in FIG. 14, only two levels can be loaded when loading into a container. For this reason, the number of products to be loaded per container has been significantly reduced, and as a result, there has been an economic disadvantage such as an increase in transportation costs for the products.

[0010] On the other hand, in order to eliminate such economical disadvantages, in order to stack the existing washing machines in three stages, the height of the products at the time of stacking may be reduced. However, in this case, it is necessary to consider the following conditions.

That is, when the washing machine is installed at the installation location so as to use the washing machine, as shown in FIG. Gap D must be kept constant. This is because when the outer tub vibrates due to the imbalance due to the rotation of the washing tub during washing and dehydration and the eccentricity of the laundry, even if the outer tub hangs down, the clutch mounted on the lower end of the outer tub, etc. To prevent the drive unit from hitting the installation bottom surface, and prevent soap bubbles caused by detergent water, which is not drained to the outside of the washing machine when the washing machine is used, from flowing into electric components such as the motor 151 and causing dielectric breakdown. To do that.

On the other hand, as a specific method for reducing the height of the washing machine, there is a method of reducing the height of the out case or the silent base. However, in this case, the gap from the bottom surface to the lower end of the clutch becomes narrower. In order to secure a constant gap from the bottom surface to the lower end of the clutch, the length of the spindle leg 40a provided on the bottom surface of the silent base 2a is reduced. I can only extend it. But,
There is a limit in extending the length of the spindle leg 40a. This is because if the length of the spindle leg 40a is too long when the washing machine is installed, the stability is deteriorated, such as occurrence of a large amount of vibration when the washing machine is operated, and the appearance is also deteriorated.

[0013] Therefore, due to such a problem, the conventional washing machine not only requires a large amount of packaging material at the time of product packaging, but also has a problem that three-stage loading is impossible at the time of loading and transporting the product. Could not be resolved.

[0014]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has an object to reduce the height of the existing product at the time of packaging and loading, and to reduce the height of the existing product at the time of installation.
