Method and device for washing inside and outside of the washing machine in which the tub is rotated

The present invention relates to a washing machine in which a tub is rotated, and in particular, the washing process is performed by tilting the washing tank and the washing tank at a predetermined angle during the washing process of the washing machine, and during the dehydration process, the dehydration process is performed by setting the washing tank and the outer tank correctly. The present invention relates to a washing method and an apparatus for tilting an inner tub of a washing machine in which a tub is rotated to lower the degree of poking and washing of the laundry contained in the washing tub.

The configuration of a washing machine performing washing by rotating a conventional barrel is shown in FIG.

That is, the above structure is the washing machine (1) and the outer tub (2) suspended on the snubber bar (15) inside the washing machine (1) and the motor (2) which combines the stator (4) to the hub (14) of the washing tub ( 3) a rotor 5 formed in the rotor, a drive shaft 6 coupled to the rotor 5 to be rotated, and a washing inner tub installed in the laundry outer tub 2 coupled to and rotated at an end of the drive shaft 6. (8), washing blades (7) provided on the bottom surface of the washing inner tank (8), and a plurality of washing protrusions (11) protruding into the inner circumference of the washing inner tank (8) and contact with the laundry; And a plurality of washing holes 10 formed at the periphery of the washing inner tank 8 to circulate the washing water, and the washing water collected in the washing outer tank 2 through the washing holes 10. It is configured to have a drain hose 13 connected to the bottom surface of the laundry outer tub (2) to be discharged to the outside by the).

In addition, the inside of the laundry, the outer tank (8) (2) is inclined to perform the washing and hemging process, and when dehydration, the configuration of the laundry inside, the outer tank (8) (2) to set up correctly is the laundry outer tank (2) and out A seating groove 27 formed in the support plate 26 in order to couple the upper end of the snubber bar 15 that acts as a damper by connecting the case 21;

The worm 25 is attached to the support plate 26,

A worm gear 24 meshed with the worm 25 to lift the worm 25;

The drive motor 23 is mounted to the bracket 22 of the outer case 21 in order to transmit the rotational force to the worm gear 24.

The effects of the conventional configuration as described above will be described.

First, when the laundry is put into the washing tub 8 and the operation button is pressed, the water supply valve opens and water is made. When the water reaches the predetermined level in the washing tub 8, 2, the water supply valve is shut off to supply water. Stopped.

The worm gear 24 is rotated while the driving motor 23 mounted on the bracket 22 of the outer case 21 is rotated and the worm gear 24 is engaged with the worm gear 24 at the same time as the water supply valve is blocked. (25) is linearly moved upward.

Therefore, the support plate 26 attached to the worm 25 is also moved upward, so that the snubber bar 15 coupled to the seating groove 27 of the support plate 26 is moved upward, so that the laundry outer tub 2 and the laundry The inner tub 8 is inclined by a predetermined angle as shown in FIG.

When the inner and outer tubs 8 and 2 are inclined by the set angle, power is stopped to the driving motor 23 and power is applied to the motor 3 to perform the washing process.

That is, the stator 4 formed in the motor 3 is fixed to the hub 14 and the rotor 5 is fixed to the drive shaft 6 connected to the washing tub 8 so that the rotor 5 The drive shaft (6) and the washing inner tank (8) is rotated by the rotation to wash.

At this time, the laundry contained in the laundry inner tank (8) is able to wash the friction generated by the contact with the washing blade (7) and the washing protrusions (9) rotated with the washing inner tank (8). do.

On the other hand, in the washing, the outer tub (8) (2) in the inclined state to complete the washing process and to perform the dehydration process in the laundry, the outer tub (8) (2) must be correctly set to the original position.

That is, in the dehydration process, it is difficult to obtain the centrifugal force in a state where the washing inner tank 2 is inclined because the washing inner tank 2 should be dehydrated by the centrifugal force while the washing inner tank 2 rotates at a high speed.

Therefore, when the above washing process is completed, the inside of the laundry, the outer tank (8) (2) is erected to stand on the dehydration process.

That is, as the driving motor 23 is rotated in reverse, the worm gear 24 is rotated in reverse, and the worm 25 engaged with the worm gear 24 is lowered.

When the worm 25 is lowered as described above, the support plate 26 attached thereto and the snubber bar 15 coupled to the seating groove 27 of the support plate 26 are also lowered to wash the inner and outer tubs 8 and 2. ) Is correctly set as shown in FIG.

Then, when the washing, the outer tub (8) (2) is set to the normal position, the motor (3) is rotated to rotate the washing blade (7) and washing tub (2) at high speed to perform a dehydration process. .

In addition, the washing water of the washing outer tank 2 discharged to the washing hole 10 of the washing inner tank 8 by the dehydration process passes through the drain hose 13 to the outside by the operation of the drain pump 12. Is discharged.

However, such a conventional tilting device requires many parts to tilt the inner tub and the outer tub 8, 2.

That is, in order to tilt the inside of the laundry, the outer tub 8, 2, many parts such as the driving motor 23, the worm gear 24, the worm 25, the support plate 26, the bracket 22, etc. As it becomes necessary, the configuration is complicated.

Therefore, there is a high risk of increase of labor costs and failures due to an increase in raw material costs, an assembly process, and the like, and a considerable difficulty in repairing the above failures has many problems such as power loss due to the driving motor.

The purpose of the present invention for solving and complementing such a conventional problem,

In addition, in the washing process of the inner and outer tubs, the first and second elastic members 124 and 134 having a small spring constant are greatly compressed by the weight of the wash water supplied to the washing tub 108 and the springs are greatly compressed. The third and fourth elastic members 144 and 154 having a high constant value were provided with a tilting process by spring constant values that tilt the inner and outer tubs 108 and 102 in a predetermined direction while being compactly compressed.

In addition, the slanting process of the inner and outer tubs is greatly compressed by the first and second elastic members 124 and 134 having a short free length of spring by the weight of the wash water supplied to the washing tub 108. The free length of the elastic member 144, 154 is provided with a tilting process by the free length of the spring to be inclined in a predetermined direction, the inner tub 108, 102 while washing slightly compressed.

In addition, the process of returning the inner position of the inner and outer tubs is carried out as the spring constant values of the first and second elastic members 124 and 134 return to their original positions due to the weight loss caused by the drainage during dehydration. 108) (102) is made up of the correct position of the inner and outer tub washing by the spring constant value is set up correctly.

In addition, the washing process of returning the inner position of the inner and outer tubs is performed in the inner and outer tubs as the free length of the springs of the first and second elastic members 124 and 134 returns to their original positions due to the weight reduction caused by the drainage during dehydration. 108) (102) is made up of the correct position of the inner and outer tub washing by the spring free field to be correctly set up.

In addition, the inclination angle α of the inner and outer tubs 108 and 102 is inclined within a range of 0 ° -20 °.

On the other hand, the configuration for inclining the inner and outer tub of the present invention will be described with reference to Figs.

In order to lower the porosity of laundry to be washed and washed in the washing tub 108 of the washing machine 101 and to increase the washing degree, the inner and outer tubs 108 and 102 by the weight of the washing water in the water supply state, that is, the washing and rinsing process Is inclined, and during the dehydration process, the first and lower spring constant values are smaller than the spring constant values of the third and fourth elastic members 144 and 154 so that the inner and outer tubs are raised to their original positions by the weight loss of the wash water. And a second elastic member 124 and 134.

In addition, in order to lower the degree of entanglement of the laundry to be washed and washed in the washing tub 108 of the washing machine 101 and to increase the washing degree, in the water supply state, that is, in the washing and rinsing process, the weight of the washing water in the washing tub and the outer tub 108 are reduced. When the 102 is inclined and dewatered, the free length of the first and second elastic members 124 and 134 is raised so that the inner tub 108 and 102 are raised to their original positions by the weight loss of the wash water. F1 was provided shorter than the free field F2 of the third and fourth elastic members 144 and 154.

Referring to the operation of the present invention as described above is as follows.

First, when the laundry is put into the washing tank 108 and the operation button is pressed, the water supply valve is opened and the water is made. When the water reaches the predetermined level in the washing tank 108, 102, the water supply valve is blocked and the water is supplied. Stopped.

Since the first and second elastic members 124 and 134 are shorter than the free field of the spring of the third and fourth elastic members 144 and 154 coupled to the 155, the first and second elastic members 124 and 134 are greatly compressed. The third and fourth elastic members 144 and 154 are slightly compressed.

Accordingly, the inner tub 108 and 102 can be tilted at about 0 ° -20 ° as shown in FIG. 5 even by the free length of the elastic members 124, 134, 144, and 154.

In the laundry as described above, the power is applied to the motor 103 in a state inclined at a predetermined angle by the wash water supplied to the outer tub 108, 102 to perform the washing process.

In this case, the laundry contained in the laundry inner tank 108 may be washed while friction resistance is generated due to the contact of the washing blade 107 and the washing protrusion 109 rotated together with the washing inner tank 108. do.

On the other hand, when the washing process is completed in the state in which the inner and outer tubs 108 and 102 are inclined, the dehydration process is continued. The dehydration process is performed by the high speed rotation of the motor 103. The washing water is discharged to the washing tub 102 through the washing hole 110.

In addition, the wash water discharged to the laundry outer tank 102 is drained to the outside by passing through the drain hose 13 by the operation of the drain pump (12).

As described above, when the washing water in the laundry, the inner tub 108, 102 is drained to the outside, the weight of the inner tub, the outer tub 108, 102 is gradually reduced.

Accordingly, the first and second elastic members 124 and 134 having a small spring constant or a short free field, which are compressed by the weight of the wash water, gradually return to each other after being relaxed. Inner laundry 108, 102 can be obtained.

On the other hand, Figure 7 is a diagram showing the degree of porosity and washing degree when washed in a state inclined the inner tub, outer tub 108, 102 according to the present invention, the angle of the inner tub, outer tub 108, 102 is 0 In a tilting angle from ˚ to 20˚, the kink degree is lowered and the cleaning degree is higher, so that it is possible to obtain improved washing performance and to prevent twisting of laundry.

According to the present invention, the spring constant values of the first and second elastic members coupled to the first and second snubber bars supporting the laundry outer tub are set to the third and fourth elasticities coupled to the third and fourth snubber bars. The free length of the springs of the first and second elastic members coupled to the first and second snubber bars is smaller than the spring constant value of the members or the third and fourth elastic members coupled to the third and fourth snubber bars. By forming shorter than the spring free field,
