Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine.

[0002]

2. Description of the Related Art In a fully automatic washing machine, for example, when a user sets washing contents at the start of washing and puts laundry into a washing / dewatering tub, water supply starts automatically thereafter. Detergent is supplied, and washing, rinsing, and spinning of the rotating blade and the washing and dewatering tub are simultaneously performed by high-speed rotation of the rotating blade to automatically complete washing.

In the washing and rinsing step, a swirl flow is generated in the washing and dewatering tub by alternately rotating, stopping and reversing the rotary blades, and the washing water and the laundry are agitated by the swirl flow to facilitate washing and rinsing. In the dehydration step, the water contained in the laundry is blown off by the centrifugal force generated by the high-speed rotation of the rotating blades and the washing and dewatering tub to dehydrate the laundry.

In addition, delicate clothing such as a sweater weakens the water flow by shortening the rotation and reversal time of the rotary wings, thereby washing easily.

[0005]

In the final dewatering step, the rotating blades and the washing and dewatering tub rotate at a high speed as described above, so that the laundry itself sticks to the peripheral wall of the tub due to centrifugal force.
It is in this state even after the completion of dehydration. For this reason, when taking out the laundry from the tub after the spin-drying, it is necessary to peel off the laundry from the peripheral wall, and it is difficult to take out the laundry.

Further, if the laundry is left in the washing and dewatering tub after the completion of the dehydration, the laundry adheres to the peripheral wall and becomes more difficult to take out, and wrinkles are generated.

[0007] On the other hand, in the washing and rinsing step, the washing power and the rinsing power are obtained from the water stream, so that the cloth may be entangled during the step.

[0008] Further, there is no difference that the clothes are agitated by the water flow even if the water flow is weakened in the delicate clothes washing and rinsing step, which is not sufficient for protection of such clothes.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the disadvantages of the prior art, to prevent the laundry from sticking to the peripheral wall of the washing and dewatering tub after the completion of the dehydrating step, to make it easier to take out the laundry, Entanglement can be reduced,
An object of the present invention is to provide a washing machine capable of providing a process for a delicate garment with less risk of impairing the feel and quality of the garment.

[0010]

According to the present invention, in order to achieve the above object, first, a water tub is suspended and supported in an outer box, and a washing and dewatering tub having a rotating blade provided on the bottom in the water tub is rotated. In a washing machine in which a motor for freely rotating and rotating a washing and dewatering tub and a rotating blade is disposed below a water tub, a motor for vibrating the water tub in a vertical direction or a horizontal direction at the bottom of the water tub. By installing a shaker and vibrating the water tub, this vibration is transmitted to the washing and dewatering tub, and the laundry stuck to the peripheral wall of the washing and dewatering tub is shaken off, and the washing water is vibrated during washing and rinsing. Let the clothes entangle.

Second, the vibrator uses a dedicated motor as a drive source, connects an eccentric rotary disk to a rotating shaft of the dedicated motor, and vibrates a water tank by rotation of the eccentric rotary disk to thereby provide a drive source. As compared with the case where the washing motor is shared, a switching gear is not required, so that the operation is more reliable.

Third, the vibrator uses a motor for rotating the washing / dewatering tub and the rotary blades as a drive source, and connects an eccentric rotary disk to a rotary shaft of the motor via a switching gear. By vibrating the water tank by the rotation, the number of display units is reduced and the space required for installation in a limited space in the outer box is reduced as compared with a case where a dedicated motor is provided as a drive source.

Fourthly, by performing the vibration after the final dehydration step, the laundry stuck to the peripheral wall of the washing and dewatering tub can be shaken off, and the laundry is left in the tub after the dehydration is completed. Even when the laundry is not adhered to the peripheral wall and wrinkles are not generated.

Fifth, by performing the vibration during the washing step or the rinsing step, the entanglement of the laundry in such a step can be reduced, and the washing power is increased by vibrating the washing water.

Sixth, the water tub is vibrated by a vibrator without rotating the rotary wings and the washing and dewatering tub, and this vibration is transmitted to the washing and dewatering tub, and water and laundry in the washing and dewatering tub are removed. By providing a delicate step of washing and rinsing by oscillating, the delicate clothes can be sufficiently protected without the laundry being swung directly by the water current.

[0016]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a longitudinal sectional side view showing an embodiment of the washing machine of the present invention. Explaining from the overall structure of the washing machine, a water tub 2 is suspended and supported in an outer box 1 as in the conventional case, The washing and dewatering tub 3 provided with the rotating wings 4 is rotatably disposed, and the rotating wings 4 and the washing and dewatering tub 3 are provided below the water tub 2.
, And a main bearing 6 are provided.

In the figure, reference numeral 7 denotes a water channel formed between the water tub 2 and the washing / dewatering tub 3, and 8 denotes a balancer provided at the upper edge of the washing and dewatering tub 3.

In such a washing machine, the vibrator 11 of the water tank 2 is used.
A dedicated motor 9 serving as a drive source is disposed below the water tank 2, and an eccentric rotary disk 10 is vertically rotatably connected to a rotary drive shaft 9 a of the motor 9, and a peripheral edge of the eccentric rotary disk 10 is When this is located above due to eccentricity, it contacts the bottom of the water tank 2 and engages to push it up.

The means for engaging the eccentric rotary disk 10 with the water tank 2 includes:
Although the peripheral edge of the eccentric rotary disk 10 may be engaged so as to directly contact the water tank 2, a horizontal member is separately provided at the bottom of the water tank 2, and the eccentric rotary disk 10 abuts on the horizontal member, and the horizontal member is interposed. Alternatively, the rotation of the eccentric rotary disk 10 may be transmitted to the water tank 2.

When the motor 9 is energized as described above, the rotary drive shaft 9a rotates, and the eccentric rotary disk 10 rotates in the vertical direction. Accordingly, when the center axis of the eccentric rotary disk 10 is located above the position of the rotary drive shaft 9a, the peripheral edge of the eccentric rotary disk 10 contacts the bottom outside of the water tank 2 and pushes it up. When the center axis is further positioned below the position of the rotary drive shaft 9a after further rotation, the peripheral edge thereof is separated from the outside of the bottom of the water tank 2, and the water tank 2 moves downward to return.

By repeating this, the water tank 2 vibrates up and down. The vibration frequency is, for example, 1 to 100H.
about z.

The operation of the vibrator 11 is performed, for example, after the final dehydration step. In the final spin-drying step, the washing and spin-drying tub 3 and the rotary blades 4 rotate at a high speed, so that the laundry sticks to the peripheral wall of the spin-drying and spin-drying tub 3 at the end by centrifugal force.

By vibrating the water tank 2 in this state,
The vibration of the water tub 2 is transmitted to the washing and dewatering tub 3, which vibrates and the laundry stuck to the peripheral wall of the washing and dewatering tub 3 is shaken off. Therefore, it becomes easy to take out the laundry from the washing and dewatering tub 3.

As another example of the operation timing of the vibrator 11, it can be performed during the washing and rinsing process. Thereby, the entanglement of the laundry due to the swirl generated by the rotation of the rotary wings 4 in such a process can be reduced, and the washing power is increased by vibrating the washing water.

Further, a delicate washing step performed by operating only the vibrator 11 without rotating the rotary blades 4 and the washing / dewatering tub 3 can be separately provided. In this case, the water tub 2 is vibrated by the vibrator 11, the vibration is transmitted to the washing and dewatering tub 3, and the water and the laundry in the washing and dewatering tub 3 are vibrated. Since washing is easily performed, the quality of the laundry can be more sufficiently ensured without the laundry being swung directly by the swirling current.

In the above embodiment, the water tank 2 is vibrated in the vertical direction. However, the present invention is not limited to this.
For example, the water tank 2 may be configured to vibrate horizontally. In this case, for example, a vertical member (not shown) is protruded downward from the bottom of the water tank 2, and the center axis of the eccentric rotary disk 10 is located on the side of the rotation drive shaft 9 a of the motor 9, and the eccentric rotary disk The eccentric turntable 10 is positioned with respect to the vertical member such that the side peripheral edge of 10 presses the vertical member from the side.

Thus, with the rotation of the motor 9,
The pressing and separation of the eccentric rotary disk 10 against the side of the vertical member are repeated, and the vertical member vibrates in the horizontal direction, and this vibration is transmitted to the water tub 2 and the washing and dewatering tub 3.

The operation when the water tank 2 is vibrated in the horizontal direction is the same as that when the water tank 2 is vibrated in the vertical direction.

In the above-described embodiment, the drive source of the vibrator 11 is provided with the dedicated motor 9. However, the present invention is not limited to this.
The motor 5 for washing and dehydration may be shared without providing the motor. In this case, an eccentric rotary disk is connected to the rotary drive shaft of the motor 5 via a switching gear. Then, only the eccentric rotary disk is rotated after the spin-drying process is completed by switching the switching gear.
