The present invention relates to a washing machine, and more particularly, to a washing machine having a pedestal for adjusting the level of the washing machine.

In general, a washing machine uses a motor as its main power, and processes washing, rinsing, and dehydration to remove contaminants from laundry using the action of detergent and water. The washing machine includes a motor, a power unit, a mechanical unit for transmitting energy to laundry, a control unit for adjusting a washing process, a water supply unit for draining water, and a drainage system. Examples of the washing machine include a drum washing machine using a drop of laundry, a stirring washing machine for rotating the stirrer from side to side, and a pulsator washing machine for rotating the pulsator to use water. Hereinafter, the drum washing machine will be described as an example.

1 is a perspective view showing a state where a drum washing machine according to the prior art is mounted on a washing machine mounting stand.

As shown in FIG. 1, a conventional drum washing machine includes a housing 1 forming an external appearance, a water tank containing washing water in the housing 1, and a drum rotatably provided in the water tank. The lower surface of the) is equipped with a leg (2) for supporting the drum washing machine.

Normally, the legs 2 are provided in plural on the lower surface of the housing 1, and are mounted side by side in two at the front and the rear. A female thread portion is formed on the lower surface of the housing 1 on which the leg 2 is mounted, and a male thread portion is formed on the leg 2 so as to be engaged with the female thread portion. Therefore, when the leg 2 is rotated, the leg 2 is moved up and down on the female screw part to adjust the height of the washing machine.

However, since the installation place of the washing machine is different for each household, the washing machine may not be mounted on the washing machine mounting stand 3. For example, as shown in FIG. 1, when the washing machine is installed on the washing machine mounting unit 3 as the washing machine is enlarged, a part of the legs 2 may not be seated on the washing machine mounting unit 3. .

In this case, the legs 2 may be rotated to level the washing machine so that the legs 2 reach the floor. However, when the length of the legs 2 is increased, it is difficult to maintain the washing machine horizontally, and the washing machine vibrates. Will not absorb.

In addition, the leg 2 of the washing machine is limited in the length that can be extended while the height (H) of the washing machine mounting stand (3) is formed differently in each home, so the level of the washing machine is maintained by adjusting the leg (2) There is a limit to this.

 In this case, the brick is used to compensate for the height (H) of the washing machine mounting unit 12, but it hurts the appearance of the washing machine, and the pedestal is also used, but the height (H) of the washing machine mounting unit (3) varies as mentioned above. There is a problem that can not be used in all homes.

The present invention has been made to solve the above problems, an object of the present invention is to provide a washing machine having a pedestal applicable to a variety of installation space by improving the structure of the pedestal for adjusting the level of the washing machine.

The present invention is devised to achieve the above object, the washing machine according to the present invention in the washing machine including a pedestal on which the legs of the washing machine, the pedestal includes an upper pedestal and a lower pedestal laminated, the lower pedestal Is characterized in that it is provided in a polyhedral shape that increases the frictional force with the ground.

In addition, the upper supporter includes a first laminated portion protruding from the lower surface, the lower supporter includes a second laminated portion formed by recessing the upper surface, the first laminated portion and the second laminated portion is engaged with each other It is characterized by.

In addition, the upper surface of the upper support base on which the leg is raised is characterized in that the mounting portion is formed recessed.

In addition, the plurality of upper pedestal is provided, the plurality of upper pedestal is characterized in that the seating portion and the first laminated portion is engaged with each other.

In addition, the lower support is characterized in that the rubber material is formed to reduce the vibration.

In addition, the lower support is characterized in that the foreign material insertion groove is formed between the ground and the foreign material is inserted to generate the cloud friction.

In addition, the polyhedral lower pedestal is characterized in that the rectangular parallelepiped.

In addition, the lower support provided in a rectangular parallelepiped is characterized in that the ratio of the length of the horizontal and vertical is 1.5: 1 ~ 2: 1.

The pedestal for washing machine according to the present invention includes an upper pedestal laminated in multiple stages to adjust the height of the washing machine; and a lower pedestal provided on the lower side of the upper pedestal to reduce vibration, wherein the upper pedestal and the lower pedestal are rectangular parallelepiped. It is provided in a shape.

Hereinafter, a preferred embodiment of the washing machine according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a perspective view showing a state in which a washing machine according to the present invention is installed on a washing machine mounting stand using a pedestal.

As shown in FIG. 2, the washing machine according to the present invention has a housing 10 forming an exterior and four legs 11 protruding downward from the bottom of the housing 10. A female screw portion is formed on the lower surface of the housing 10, and a male screw portion is formed on the leg 11 to engage the female screw portion. Therefore, as the leg 11 rotates, the length of the leg 11 protruding from the lower surface of the housing 10 is stretched so that the height of the washing machine can be adjusted.

In addition, the housing 10 is provided with a water tank (not shown) in which washing water is contained, a drum (not shown) rotatably provided in the water tank, and a driving motor (not shown) for imparting rotational force to the drum. Laundry and washing water are put into the drum, so when the drum rotates, the eccentricity acts on the washing machine. Therefore, it is important that the washing machine is provided so that slippage does not occur in the ground according to the rotation of the drum. In addition, it is important to keep the washing machine horizontal to suppress the vibration generated when the washing machine rotates.

However, as shown in FIG. 2, the washing machine mount 12 is formed to protrude from the ground, and two legs 11 mounted at the front of the legs 11 of the washing machine are deviated from the washing machine mount 12. In this case, the height H of the washing machine mounting stand 12 is too large, and only adjusting the length of the leg 11 has a limit in keeping the washing machine horizontal and suppressing vibration. At this time, the pedestal 20 for adjusting the height of the washing machine so that the washing machine is horizontal is located between the leg 11 and the ground.

The pedestal 20 can be used regardless of the number of legs 11 that deviate from the washing machine mount 12. For example, as in the present invention, the two legs 11 may be detached from the washing machine mounting unit 12, or one leg 11 may be detached from the washing machine mounting unit 12. In addition, even if there is no washing machine mounting stand 12, when a step is formed in the place where the washing machine is installed, one or a plurality of pedestals 20 may be used to keep the washing machine horizontal.

3 is a perspective view showing a pedestal of the washing machine according to the present invention, Figure 4 is an exploded perspective view showing a pedestal of the washing machine according to the present invention.

As shown in FIGS. 3 and 4, the pedestal 20 is composed of an upper pedestal 21 positioned at an upper side and a lower pedestal 25 positioned at a lower side thereof. The upper pedestal 21 and the lower pedestal 25 are each other. They are interlocked and stacked. In addition, as shown in Figure 2, when the height (H) of the washing machine mounting stand 12 is provided so that the upper base 21 can be additionally stacked.

First, a structure in which the lower pedestal 25 and the upper pedestal 21 are stacked will be described. The upper surface of the lower pedestal 25 is provided with a second laminated portion 26 formed in a predetermined depth, and the upper pedestal 21 of The first stacked portion 24 protruding downward is provided on the lower surface. At this time, since the first stacking portion 24 is inserted into the second stacking portion 26, the lower support 25 and the upper support 21 are interlocked and stacked.

Next, looking at the structure in which the plurality of upper pedestal 21 is stacked, the seating portion 22 formed by recessing a predetermined depth is provided on the upper surface of the upper pedestal 21. In this case, since the first stacking part 24 of the other upper supporter 21 is inserted into the seating part 22, the plurality of upper supporters 21 are stacked to be engaged with each other. The seating portion 22 has a shape substantially the same as that of the second stacked portion 26. However, the seating portion 22 is formed with a plurality of grooves 23 of a predetermined depth to prevent slipping when the leg 11 is supported.

Thus, if the upper support 21 and the lower support 25 are provided to be stacked, even if the installation space of the washing machine (for example, the height (H) of the washing machine mounting stand 12 shown in Figure 2) is different for each home There is an advantage to this. However, such a laminated structure may generate a gap between the upper support 21 and the lower support 25 due to the vibration of the washing machine to react sensitively to the vibration. Below, the shape provided so that the base 20 may be tough with respect to vibration is demonstrated.

The pedestal 20 has an approximately rectangular parallelepiped shape. This is because the upper support 21 and the lower support 25 also have a substantially rectangular parallelepiped shape, the lower support 20 increases the frictional force with the ground and the lower support 20, the upper support 20 and the upper support 20 And the top support 20 are small enough to be spaced apart from each other to increase the robustness against vibration. More specifically, the experimental results measured for the vibration characteristics with the length-to-length ratio of the pedestal 20 set to 2: 1 or 1.5: 1 are the best. In this case, when the horizontal portion is formed to be relatively longer in length, the vibration characteristics of the washing machine become better when the horizontal portion is installed in parallel with the edge portion 13 (see FIG. 2) where the front and bottom surfaces of the washing machine meet. How to set the length ratio of the width and length of the pedestal 20 is determined in consideration of the effect of vibration reduction and cost reduction effect such that the length ratio of the length and width is in the range of 1.5: 1 ~ 2: 1 It would be desirable.

In addition, pp (propane propylene) is used as the material of the upper support 21, a rubber material is used as the material of the lower support (25). Since the rubber material is stronger in vibration characteristics as the hardness is stronger, it may be desirable to determine the material of the lower support 25 in consideration of this.

5 is a cross-sectional view showing two states of the bottom structure of the lower support according to the present invention.

As shown in FIG. 5, when the bottom of the lower support 25 is formed in a flat pattern, and there is a foreign matter 28 such as sand grains between the bottom of the lower support 25 and the ground, it is momentarily caused by vibration of the washing machine. As a result, the frictional force is reduced, so that the washing machine may flow. That is, when the bottom of the lower support 25 is in contact with the ground as a whole, the static frictional force acts, but if there is a grain of sand between the bottom of the lower support 25 and the ground friction may act. Therefore, since the rolling friction is less than the static friction, the flow of the washing machine may occur instantaneously.

Therefore, in the present invention, a plurality of foreign material insertion grooves 27 having a predetermined depth are formed on the bottom of the lower support 25. Therefore, foreign matters such as sand grains are inserted into the foreign substance insertion groove 27, and the static friction force acts between the bottom of the lower support 25 and the ground to prevent flow due to the vibration of the washing machine. In particular, since the lower support 25 is formed of a rubber material, the static friction force between the lower support 25 and the ground is very large so that the washing machine does not react sensitively to vibration.

Through the configuration as described above, when the washing machine is installed by providing a pedestal stacked in multiple stages, the washing machine can be horizontally maintained even if the installation site has a step, and even if the height of the step is different for each installation site, various applicable washing machines can be provided. It can be effective.

In addition, by providing a pedestal having a rectangular parallelepiped shape to ensure maximum robustness to the vibration of the washing machine has an effect of providing a safer and improved satisfaction washing machine.
