However, the conventional technique has a problem that the leg level is adjusted by the feeling of the user, so that the proper level is not always maintained. The present invention is to solve this problem, and a first object thereof is to provide an inclined state display portion as a measure when the user adjusts the rubber feet so that the user can appropriately adjust the levelness. To do.

A second object of the present invention is to provide a washing machine which automatically maintains the levelness by judging the inclination angle and automatically adjusting the rubber feet.

[0005]

A first means for solving the above-mentioned problems is to provide a washing tub, a support rod for hanging down the washing tub, a main body to which the support rod is connected, and the support rod. A weight sensor that detects the weight of the washing tub from the applied tension,
An inclination angle determination means for determining the inclination angle of the main body from the detection value of the weight sensor, an inclination state display section for displaying the inclination state of the main body based on the determination result of the inclination angle determination means, and an inclination of the main body. The washing machine is provided with an adjustable leg rubber for adjusting a corner.

The second means is a washing tub, a support rod for hanging down the washing tub, a main body to which the support rod is connected, and a weight sensor for detecting the weight of the washing tub based on the tension applied to the support rod. , An inclination angle determining means for determining an inclination angle of the main body based on a detection value of the weight sensor, an automatic adjusting foot for adjusting the inclination angle of the main body, and the automatic adjustment based on the determination result of the inclination angle determining means. The washing machine is provided with a control unit that controls the adjusting feet.

[0007]

According to the washing machine of the first means, since the inclination state of the washing machine is displayed on the inclination state display portion, the user can adjust the inclination angle while confirming the inclination state of the washing machine. . Further, according to the washing machine of the second means, the inclination angle of the main body is automatically adjusted according to the judgment result of the inclination case judging means, so that the washing machine can always be kept in parallel. By these actions, it is possible to prevent the suspension of dehydration due to abnormal vibration caused by the inclination of the main body during dehydration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a block diagram of a washing machine for explaining a first embodiment of the present invention. In the figure, reference numeral 1 denotes a washing tub, which is connected to the main body 3 by four supporting rods of 2. Reference numeral 4 denotes a weight sensor that detects the tension applied to the support rods 2, and is attached to each support rod 4. Reference numeral 5 is an adjusting foot rubber for adjusting the inclination of the main body 4, and the height of the foot can be adjusted by a screw method. Reference numeral 7 is an inclination angle determining means for determining the inclination angle of the main body 3 from the detection value of the weight sensor 4.
Reference numeral 8 is a display unit control means, which controls the display state of the tilt state display unit 6.

The structure and operation of the weight sensor 4 will be described with reference to FIG. The suspension 20 expands and contracts due to the weight of the washing tub 1, and accordingly the ferrite 21 moves up and down, whereby the inductance of the coil 22 changes. As a result, the oscillation frequency of the oscillation circuit 23 changes, and the weight of the tank can be detected by detecting the amount of this change with the microcomputer. The inclination state determination means 7 calculates the center of gravity from the detection values of the four weight sensors 4 and estimates the inclination angle of the main body 3 from the result. As shown in FIG. 4, the tilted state display unit 7 has nine LEDs lined up vertically and horizontally.
The LED is lit up in the direction of inclination. FIG. 4 shows that the main body 3 is tilted to the right. The display unit control means 8 determines whether the LED is turned on or off based on the determination result of the inclination angle determination means 7 and controls it. By operating the adjusting rubber feet 5 based on this display, the main body 3 can be easily installed horizontally.

In the example of FIG. 4, the body 3 is tilted to the right. Therefore, the height of the right adjusting foot rubber 5 should be increased or the height of the left adjusting foot rubber 5 should be decreased. Then, the main body 3 can be installed horizontally by adjusting the inclination angle so that only the LED in the middle of the display of the inclination state display unit 7 lights up. Here, the inclination angle determining means 7 and the display control means 8 can be easily realized by the microcomputer 9.

Next, a second embodiment will be described with reference to FIG.
In the figure, reference numeral 10 denotes a washing tub, which is connected to the main body 12 by four 11 supporting bars. Reference numeral 13 denotes a weight sensor that detects the tension applied to the support rods 11, and is attached to each support rod 11. Reference numeral 14 denotes an adjusting leg rubber for adjusting the inclination of the main body 12, which is driven by an adjusting motor 15 via a speed reducer 16. Reference numeral 17 is an inclination angle determining means for determining the inclination angle of the main body 12 based on the detection value of the weight sensor 13.

The structure and operation of the weight sensor 13 will be described with reference to FIG. The suspension 25 expands and contracts due to the weight of the washing tub 10, and accordingly the ferrite 26 moves up and down, whereby the inductance of the coil 27 changes. As a result, the oscillation frequency of the oscillation circuit 28 changes, and the weight of the tank can be detected by detecting the amount of this change with the microcomputer. The inclination state determination means 17 is 4
The center of gravity is calculated from the detection values of the two weight sensors 13, and the tilt angle of the main body 12 is estimated from the result. The adjusting motor control unit 18 determines whether to adjust the tilt motor based on the determination result of the inclination state determining unit 17.
By controlling the two adjusting motors 15, the heights of the four adjusting foot rubbers 14 are adjusted so that the main body 12 becomes horizontal. By this operation, horizontal installation of the washing machine is automatically performed.

The effects of the present invention described above will be described below.

According to the first aspect of the invention, the user adjusts the rubber feet while monitoring the inclination state of the washing machine,
The washing machine can be installed horizontally easily. The second
According to the invention, the inclination state of the washing machine is automatically adjusted, so that the washing machine is always installed horizontally. By keeping the washing machine horizontally installed as described above, it is possible to prevent in advance the suspension of dehydration due to the abnormal vibration during dehydration due to the inclination of the main body.

According to the second invention, the tilting of the washing machine is detected by the same mechanism as in the first invention, and as a result, the horizontal installation of the washing machine is automatically maintained, and the trouble of manual adjustment is eliminated. In addition, it is possible to make sure adjustments.
