Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine having both dehydrating and adjusting legs for adjusting the inclination of a washing machine main body.

[0002]

2. Description of the Related Art As is well known, when installing a dehydrating / washing machine, if the installation location is not flat or inclined, the length of the washing machine is adjusted by adjusting legs provided at a lower end portion of the main body of the washing machine. In this case, the dehydration washing machine is prevented from being installed in an inclined state. The adjustment of the inclination by the adjusting leg also depends on the intuition of the installer in determining whether or not the inclination has been corrected. Therefore, depending on the case, there is a case where the installation is performed with a slant without being sufficiently corrected. In such an installed state, the water receiving tub storing the rotating tub is elastically suspended in the washing machine main body by the elastic suspension mechanism. When the operation is performed in this biased state, when the rotating tub rotates during the spin-drying operation and the water receiving tub swings, the safety switch that completely stops the operation of the dehydrating washing machine due to the swing of the water receiving tub operates. It will be easier. If the installed state of the main body of the washing machine exceeds a predetermined inclination limit, the safety switch is activated during the spin-drying operation and the operation is stopped halfway.

In order to prevent the washing machine from being installed in an inclined state without being sufficiently corrected, a mark corresponding to a top cover provided with a laundry entrance and a water receiving tub of a washing machine body is provided. There has been proposed a configuration in which it is possible to confirm that the installation has been performed normally by aligning the corresponding marks with each other. In addition, a configuration has been proposed in which a level can be attached to the top cover and the level can be set with the level to confirm that the installation has been performed normally.

However, in the above prior art,
At the time of installation, the adjusting feet provided at the lower end of the washing machine body must be adjusted, and each time the adjustment is made, it must be checked at the top of the washing machine body whether the adjustment is appropriate. It was very annoying.

[0005]

In addition, at the time of dehydration, dehydration is performed by rotating both the stirring body and the washing / dehydrating tub at high speed.

On the other hand, the adjusting leg 5 attached to the front leg attaching portion at the four corners of the base plate 3 has a substantially cylindrical leg rubber 14 whose lower surface abuts the floor surface of the installation location, and the head of the bolt 15 Is formed by embedding, and the screw portion is extended upward. Then, the adjustment leg 5 rotates the bolt 15 screwed to the base plate 3 to advance and retreat the adjustment of the leg length,
This can be achieved by appropriately adjusting the amount of downward extension from the base plate 3. Therefore, by adjusting the screwing amount of the adjusting leg 5 into the base plate 3, the washing machine main body 4 can be horizontally installed even if the floor surface is inclined or has a step.

A leg nut 16 is screwed to one of the adjusting legs 5 at an intermediate portion of the bolt 15. The leg nut 16 has a concave portion 1 at the upper end of a cylindrical body portion 17 having a female thread.

If the washing machine main body 4 does not fall out of position 2, it can be confirmed that the washing machine main body 4 has already been installed in a substantially horizontal state with a range of inclination smaller than the allowable inclination angle θ, and the adjustment by the adjustment leg 5 is unnecessary.

On the other hand, when the small iron ball 21 rolls out of the depression 22, the washing machine main body 4 is not installed within the range of the inclination smaller than the allowable inclination angle θ, and gravity acts according to the inclination of the flat surface. As a result, the small iron ball 21 rolls, and when the washing machine main body is inclined to the allowable inclination angle θ or more, the small iron ball 21 rolls out from the recess 22, so that the installation is performed in a horizontal state. It is found that there is no adjustment, and adjustment by the adjustment leg 5 for horizontal installation is required. Then, the bolt 15 is rotated to adjust the leg length of the adjusting leg 5 so that the small iron ball 21 does not fall out of the recess 22. By adjusting the leg length of the adjustment leg 5 in this manner, the washing machine main body 4 is installed in a substantially horizontal state with a range of inclination smaller than the allowable inclination angle θ. Thereafter, the leg nut 16 is tightened to such an extent that the tooth portion of the toothed washer 23 on the concave portion 18 bites into the lower surface of the leg mounting portion of the base plate 3, and the bolt 15 does not rotate with the leg nut 16 as a lock nut. Then, the adjustment leg 5 is fixed to the base plate 3.

As described above, when the washing machine main body 4 of the shelf 20 of the leg nut 16 screwed to the adjusting leg 5 is horizontally installed, the flat iron recess 22 becomes horizontal when the small iron is installed. The ball 21 is placed, and the leg length of the adjusting leg 5 provided on the front side of the washing machine main body 4 is easily and quickly adjusted so that the installer takes the same posture so that the small iron ball 21 does not fall out of the recess 22. Can be adjusted. Thus, the washing machine body 4
By simply correcting the inclination at the lower part of the washing machine, the washing machine main body 4 can be easily installed in a substantially horizontal state within a range of inclination smaller than the allowable inclination angle θ without any troublesome work.

In such a construction, when installing, the shelf 3 of the leg nut 31 screwed to the bolt 15 is installed.
The small iron ball 21 is placed on the flat surface of No. 3 so as to be aligned with the pair of vertical ribs 34. Then, watching whether the small iron ball 22 is displaced from the position of the pair of longitudinal ribs 34 that are rolled and aligned, the washing machine body is installed in a substantially horizontal state in a range of inclination smaller than the allowable inclination angle θ. Check whether it has been done. When the small iron ball 22 rolls and deviates from the position of the aligned vertical rib 34, the washing machine body is inclined at an allowable inclination angle θ or more, so that the bolt 15 is turned to adjust the leg length of the adjusting leg 5. The inclination of the main body of the washing machine is corrected so that the small iron ball 22 does not roll on the flat surface of the shelf 33.

After the main body of the washing machine is substantially horizontal, the leg nut 31 is tightened until the tooth portion of the toothed washer 23 on the recess 18 bites into the lower surface of the leg mounting portion of the base plate. Using the leg nut 31 as a lock nut, the bolt 15 is prevented from rotating, and the adjusting leg 5 is fixed to the base plate.

As described above, the small iron ball 21 is placed on the flat surface of the shelf 33 of the leg nut 31 screwed to the adjusting leg 5 so that the small iron ball 21 is not rolled. The leg length of the adjusting leg 5 provided on the front side of the main body can be adjusted while the installer takes the same posture. In this manner, as in the first embodiment, the washing machine main body 4 can be simply corrected at the lower portion of the main body of the washing machine without any troublesome work.

For this reason, when the flat surface is inclined, the small iron ball 21 rolls due to gravity acting in the inclined direction, and when the washing machine body is inclined at the allowable inclination angle θ or more, The small iron ball 21 rolls out of the recess 22. Further, on the inner surface side of the transparent cover 45, a partition wall 46 having an arc-shaped cross section that crosses the inside of the transparent case 42 is formed.

With the above-described structure, at the time of installation, the recess 22 in the flat surface of the shelf 43 serving as the bottom surface of the transparent case 42 of the leg nut 41 screwed to the bolt 15 is installed.
The small iron ball 21 housed in the transparent case 42 is placed while rotating the transparent cover 45 and pressing the small iron ball 21 with the partition wall 46. Thereafter, it is determined whether or not the small iron ball 21 rolls out of the recess 22 to determine whether or not the rinsing machine body is installed in a substantially horizontal state with a tilt range smaller than the allowable tilt angle θ. When the small iron ball 22 rolls out and rolls on a flat surface, the washing machine body is inclined at an allowable inclination angle θ or more, so the bolt 15 is turned to adjust the leg length of the adjusting leg 5, By rotating the transparent cover 45 again, the inclination of the main body of the washing machine is corrected so that the small iron balls 21 placed in the depressions 22 do not roll out.

After the main body of the washing machine is substantially horizontal, the leg nut 41 is tightened until the teeth of the toothed washer 23 on the recess 18 bite into the lower surface of the leg mounting portion of the base plate. The leg 15 is fixed to the base plate by using the leg nut 41 as a lock nut so that the bolt 15 does not rotate.
