Description

Leveling device for washing machine {device for adjusting level of automatic washing machine}

The present invention relates to a leveling device for a washing machine, and more particularly, to improve the structure of the height adjusting device for leveling the washing machine when installing a product so as to lower the height of the sound insulation panel.

In general, a washing machine removes various contaminants attached to clothes and bedding by emulsifying the detergent, friction action of the water flow due to the rotation of the pulsator, and impact action of the washing wing on the laundry. As the sensor detects the amount and type of laundry, the washing method is automatically set, and the washing water is supplied to an appropriate level according to the amount and type of the laundry, and then washing is performed under the control of the microcomputer.

The lower part of the washing machine having such a function is provided with height adjusting means for adjusting the height of the product at the installation place to level the front, rear and left and right directions.

This is because in most cases, the floor surface on which the washing machine is installed is not flat due to the drainage relationship, and thus the balance of the washing machine is balanced by using the height adjusting means. Because it can reduce.

An example of a height adjusting device provided in a conventional washing machine will be described with reference to FIG. 1.

First, the conventional washing machine has a control leg (40a) that is screwed to the front surface (F) of the sound insulating plate 2a (silent base) fixed to the bottom surface of the outer case 1, and screwed to the rear of the sound insulating plate (2a) Height and horizontal adjustment is performed by the rubber foot (5) (rubber toe).

The adjustment leg 40a is mounted on both sides of the front surface of the sound insulation plate 2a forming the bottom of the washing machine. Consists of the head portion 401 to be in contact with the bottom surface is installed, it is possible to adjust the height while supporting the load of the washing machine.

At this time, the threaded portion 400 of the adjustment leg 40a is screwed into a screw groove (not shown) formed in a corresponding portion of the bottom surface of the sound insulation plate 2a, and the height thereof is rotated as the external force acts. It is designed to control.

That is, a screw groove is formed on the bottom surface of the sound insulating plate 2a, and the adjusting leg 40a is rotated with respect to the base by rotating the adjusting leg 40a while the adjusting leg 40a is screwed to the screw groove. ) To adjust the horizontal height.

On the other hand, the rubber foot (5) made of a rubber material is fixed to both sides of the rear surface (R) of the base.

The rubber foot 5 is fixed to the screw (S) is fastened to the bottom surface of the sound insulating plate (2a) through a through hole 500 penetrating the center as shown, thereby height adjustment is impossible.

As described above, the conventional washing machine horizontal adjustment device is a pair of adjustment legs (40a) that are installed to be adjustable height on both sides of the front of the base, a pair of rubber feet (5) which is fixed to the rear both sides of the base is impossible to adjust the height. This leveling device is configured to be separately managed from the sound insulation plate 2a in the loading and transporting step of the product, which is a step before the product is installed on the floor on which the washing machine is installed.

On the other hand, such a horizontal adjustment device when the washing machine is installed in the installation place when using the washing machine, the distance from the lower end of the clutch to the installation bottom so that the interference between the lower end of the clutch (not shown) and the floor on which the washing machine is installed does not occur It also plays a role in increasing the number of people.

That is, since the adjustment leg 40a is mounted on the sound insulation board 2a, the distance from the lower end of the clutch to the bottom surface on which the washing machine is installed becomes large enough, even when the outer tank sags downward due to the weight of the laundry and the washing water. The phenomenon that the lower end of the clutch hits the installation bottom does not occur.

On the other hand, since the length of the adjustment leg (40a) can not be unconditionally lengthened, in order to increase the distance between the clutch and the bottom surface on which the washing machine is conventionally installed, the height of the outer case 1 or the sound insulation plate 2a is increased. Also give.

Therefore, in the manufacturing process of the washing machine in consideration of these points, the height of the outer case 1, the height of the sound insulating plate (2a), and the length of the adjustment leg (40a) is designed appropriately.

However, in the conventional washing machine, due to the structural characteristics of the leveling device, the height of the control leg is removed, the height is high, the packaging material takes a lot of packaging material, the height of the packaged product (7a) is large and loaded when loading the product There was a problem such as increased space.

That is, in the case of the existing washing machine, the height of the product (h _C ) of the product in the state removing the control leg (40a) is large, the packaging material takes a lot when packing, as shown in Figure 14 when loading in the container, the container (8) According to the standard, the three-stage loading of the product (7a) is impossible, so that only two-stage loading can significantly reduce the number of products loaded per container, resulting in an economic disadvantage such as an increase in transportation costs for the products. There was an issue going through.

The present invention is to solve the above-mentioned problems, while the height of the packaging and loading is reduced compared to the existing product, while improving the structure to maintain the same height as the existing product at the time of installation, required for product packaging It is an object of the present invention to provide a leveling device for a washing machine that can reduce packaging materials and reduce transportation costs while preventing interference between the clutch and the floor where the washing machine is installed.
