Description

washer

The present invention relates to a washing machine for washing laundry in a combined laundry dehydration tank.

The conventional washing machine has the structure as shown in FIG. The configuration will be described below.

As shown in FIG. 11, the washing combined use dehydration tank 1 arrange | positions the stirring blade 2 rotatably on the bottom, and installs the drip tank 3 in the outer side of this combined use dehydration tank 1. The bottom of the drip tank 3 is equipped with a washing / dehydration tank 1 and a motor 4 for driving the stirring blades 2, and through a clutch device 5 for switching the driving section, the washing / dehydration tank It is configured to drive (1) or the stirring blade (2). In addition, the drip tank 3 is dust-proof supported by the outer frame 6 via the suspension 7. The fluid balancer 8 in which the liquid is internally sealed is fixed to the upper part of the washing / dehydration tank 1. The upper surface of the drip tank 1 is covered with a drip tank cover 9.

In the above structure, in the washing stroke, the washing liquid is put into the drip tank 3, and the laundry (clothing) put into the washing / drying dehydration tank 1 is stirred by the stirring vane 2 to wash the washing liquid to the laundry. Penetrate and remove dirt by kneading the laundry. In a rinsing stroke, water is put in the drip tray 3, it stirs by the stirring blade 2, and wash | cleans laundry. In the dehydration stroke, the clutch device 5 is switched, the rotation of the motor 5 is transmitted to the washing / dehydration tank 1, and the water of the laundry is centrifugally dewatered by rotating the washing / dehydration tank 1.

Each of these strokes is gradually controlled to configure automatic washing, rinsing, and dehydration.

In such a conventional configuration, a large capacity of the washing capacity has been advanced these days, and a washing capacity of 8 kg or more has emerged. For this reason, in order to infiltrate the washing liquid in the whole laundry in the washing combined-use dehydration tank 1, and to transmit the rotation of the stirring blade 2 to the whole laundry, the rotational force of the stirring blade 2 is made strong, or stirring force is applied. As a result, it has been a problem that, at the same time, the laundry (clothing) is damaged while the laundry is removed, and the laundry is entangled.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems, and by circulating the washing liquid without adding mechanical force by stirring blades to the laundry in the combined washing and dehydration tank, without damaging or tangling the laundry.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described, referring drawings.

Example 1

As shown in FIG. 1, the combined use dehydration tank 10 has many small holes in an inner wall surface, and the stirring blade 11 is arrange | positioned rotatably in the bottom surface. The drip tray 12 is provided in the outer side of this washing | cleaning combined use dehydration tank 10. As shown in FIG. On the bottom of the drip tray 12, a washing-and-dry dewatering tank 10 and a motor (drive means) 13 for driving the stirring vane 11 are mounted, and the clutch device 14 which switches over the driving unit, It is configured to drive the washing combined use dehydration tank 10 or the stirring vane 11.

The drip tank 12 is dust-tightly supported through the suspension 16 in the outer frame 15. The channel cover 17 is fixed to the inner wall of the washing / dehydration tank 10 to form a circulation channel 18. The circulation path 18 is a lower wing integrally installed on the rear surface of the stirring blade 11 ( 19 is connected between the pump chamber 20 formed on the outer circumference of the lint filter 21 of the upper part of the washing and dehydrating tank 10.

The fluid equilibrium device 22 in which the liquid is sealed is fixed to the upper portion of the washing / dehydration tank 10. The upper surface of the drip tank 12 is covered with a drip cover 23. The packing member 27 is interposed between the drip tank 12 and the drip tank cover 23 to secure a watertight seal.

The drain valve 24 drains the laundry in the drip tank 12, and the feed valve 25 feeds the drip tank 12. The control device 26 controls operations of the motor 13, the drain valve 24, the water supply valve 25, and the like, and gradually controls a series of strokes of washing, rinsing, and dehydration.

And when washing the laundry which is easy to be damaged, by rotating driving the combined-use dehydration tank 10 at 300 rpm, for example in each process of washing and rinsing, by rotating-driving this combined use dehydration tank 10 by rotation. By the pumping action, the washing liquid between the washing-use dehydration tank 10 and the water receiving tank 12 is moved to approximately the center of rotation of the washing-use dehydrating tank 10 from between the washing-use dewatering tank 10 and the drip tank cover 23. It is set as the structure which discharges toward.

When the operation is explained in the above configuration, the laundry is put into the washing-and-drying dewatering tank 10, the water supply valve 25 is turned on to supply water, and the washing-and-drying dehydrating tank 10 is rotated. The washing liquid rises as if the washing liquid pushes up the inner surface of the drip tank 12 from the bottom, and the washing liquid raised between the washing combined-use dehydration tank 10 and the drip tank 12 is the upper drip tank cover 23. ) And change the direction so as to discharge toward the center of rotation of the washing / dehydrating tank 10 from between the washing / dehydrating tank 10 (upper surface of the fluid balancer 22) and the drip cover 23. .

The discharged washing liquid passes through the laundry, and then passes through a plurality of small holes provided on the inner wall surface of the washing / drying dehydration tank 10 to move between the washing / drying dehydration tank 10 and the drip tank 12. Circulate By circulating this washing liquid, when the washing liquid passes through the laundry, the dirt of the laundry can be removed. In particular, since the washing liquid is discharged from between the washing-use dehydrating tank 10 and the drip tray cover 23 toward the rotational center of the washing-use dehydrating tank 10, the washing liquid is effectively penetrated into the entire laundry by centrifugal force. You can.

The washing liquid which rotates the washing combined use dehydration tank 10 and rises as if the inner surface of the drip tank 12 is pushed up from the bottom by the centrifugal force by rotation contacts the drip tray cover 23, changes the direction, and uses the washing combined use. Since it is discharged between the dehydration tank 10 and the drip tray cover, the pressure for discharge is applied to the fitting part of the drip tank 10 and the drip tank cover. For this reason, the packing member 27 is interposed in order to prevent leakage. This causes damage to the laundry by circulating the washing liquid without worrying about water leakage due to the pressure for discharge and without adding mechanical force by the stirring blades 11 or the like to the laundry in the washing / drying dehydration tank 10. I can wash it without tangle.

In addition, although the packing member 27 is comprised using a sponge material, a rubber material, a putty material, etc., it is the same about an effect.
