Washing machine {WASHING MACHINE}

The present invention relates to a washing machine, and more particularly, to a washing machine having an improved structure for the rapid loading and washing of the drum.

In general, a washing machine is an apparatus for washing laundry through a process of washing, rinsing, and dehydrating to remove contaminants from laundry contained in the drum by using the washing water and detergent supplied into the tub.

Looking at the washing process of the washing machine, first, the quantity of clothes and the like put into the drum is measured, and the quantity of washing water and detergent and the total washing time are set according to the measured quantity, and then washing through the rotation of the drum with the whole washing time. A washing stroke is performed to separate the stains on laundry by friction between water and laundry.

When the washing administration is completed, the turbid wash water is discharged into the tub, and new washing water is supplied to the tub to rinse the laundry for a predetermined number of times. When the rinsing stroke is completed, the water in the tub is discharged and the drum is rotated at a high speed to perform a dehydration stroke to remove the laundry water by centrifugal separation.

Here, in the case of washing with simply washed water in the washing administration of the washing machine, the packing of the laundry is not smoothly performed, and a considerable time is required even when the detergent is decomposed.

In addition, there is a problem that the laundry is not efficiently made by the laundry detergent absorption due to this is also delayed.

On the other hand, as the washing machine is used, the drum generates foreign matters on its surface. When cleaning the drum through a simple washing course, it is not easy to remove foreign matters on the outer surface of the drum. Hygienic problems are caused by

FIG. 2 is a view illustrating first and second flow paths in the washing machine of FIG. 1, and FIG. 3 is a front sectional view schematically illustrating that the first and second flow paths in the washing machine of FIG. 2 are installed and sprayed on a tub.

Referring to the drawings, the present invention includes a circulation pump 170 and the first and second flow paths 180, 190 to circulate some of the wash water in the tub 120.

The circulation pump 170 serves to draw back part of the wash water in the tub 120 and then re-introduce it. The circulation pump 170 is disposed below the tub 120 and provides power for circulating the wash water in the tub 120.

The circulation pump 170 configured as described above circulates some of the wash water supplied through the water supply hose 192 to speed up the core of the drum 130 and to help dismantle the detergent for washing. In addition, since the rinsing water is circulated by the circulation pump 170 during the rinsing cycle, the rinsing efficiency of the laundry is increased.

Here, the circulation pump 170 is connected to the bottom of the tub 120 to withdraw some of the wash water in the tub 120.

In addition, the circulation pump 170 is connected to the front end and the upper portion of the tub 120 by the first and second flow paths 180 and 190, respectively.

The first flow path 180 is configured to connect the front end of the circulation pump 170 and the tub 120, so that the washing water drawn out by the circulation pump 170 flows through the opening of the drum 130.

Here, although not shown in detail, a first connection hole corresponding to an end of the first flow path 180 is formed at the front end of the tub 120 to communicate with the first flow path 180.

This first connection hole, the washing water drawn out by the circulation pump 170 to guide the inflow to the inside of the drum 130 through the opening of the drum 130, the inclination of a predetermined angle toward the central side of the drum 130. Achieve.

In addition, the second flow passage 190 is branched from the first flow passage 180 and connected to the upper portion of the tub 120 to communicate with the inside of the tub 120.

As described above, the second flow passage 190 connected to the upper portion of the tub 120 has the washing water drawn out by the circulation pump 170 falling from the upper portion of the tub 120 to allow the drum through the through hole 132 of the drum 130. (130) to be introduced into.

In particular, the lift 131 configured on the inner circumferential surface of the drum 130 drops water into the laundry through the lift hole 131a provided in the groove formed therein as the drum 130 rotates.

Here, although not shown in detail, a second connection hole corresponding to an end of the second flow passage 190 is formed on the tub 120 so as to communicate with the second flow passage 190.

In the first and second flow paths 180 and 190 configured as described above, a three-way valve 198 including one inlet and two outlets is installed at a portion where the second flow path branches from the first flow path. do. The three-way valve 198 is a solenoid valve that controls the selective opening and closing of one inlet and two outlets.

This allows the washing machine to circulate water into the tub 120 through the three-way valve 198 by applying a voltage to the three-way valve 198 at an appropriate time when washing or rinsing.

Alternatively, valves capable of electrical control may be installed in the first and second flow paths 180 and 190, respectively.

On the other hand, the second flow passage 190 is preferably made of at least one hose (192). In this case, preferably, when a plurality of hoses 192 are provided with respect to the upper portion of the tub 120 to drop the circulated water, the filling of the laundry may be performed quickly.

In addition, as will be described later, the hose 192 of the second flow passage 190 also serves to remove foreign matters on the outer surface of the drum 130, and the foreign matters can be efficiently removed from the entire outer surface of the drum 130.

In this case, the nozzle 194 may be mounted at the end of the hose 192 of the second flow passage 190 to remove foreign substances on the outer surface of the drum 130 when spraying.

That is, the nozzle 194 may take the structure of the enlarged nozzle 194 to dissipate the wash water, that is, water, thereby removing foreign matter on the outer surface of the drum 130 as much as possible.

In the second flow passage 190, two hoses 192 are disposed on both sides of the drum 130, and the nozzle 194 has a constant angle range so that water sprayed during spraying is directed toward the center of the drum 130. It is more preferable to achieve. Due to this structure, it is possible to clean the outer surface of the drum 130 as efficiently as possible.

The nozzle 194 may be connected to the end of the hose 192 by a ball joint 196. Due to this ball joint, the nozzle 194 may be rotated at a predetermined angle by hydraulic pressure during the injection.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
