As shown in the drawing, there is an outer case 40 forming an appearance, and inside the outer case 40, separate washing means 100 is installed to separate and wash laundry according to quality or color.

The separating and washing means 100 includes a plurality of inner tubs 111 and 112 installed to separate and accommodate laundry, and a plurality of inner tubs 111 and 112 through partition members 121 to partition and accommodate the plurality of inner tubs 111 and 112. An outer tub 120 partitioned into two spaces, a driving means 160 installed at one side of the outer tub 120 to simultaneously drive the inner tubs 111 and 112, and installed at an upper end of one side of the outer case 40. The water supply means 130 for supplying water to the plurality of inner tanks (111, 112) at the same time or supplying water to any one of the plurality of inner tanks (111, 112), and installed on the lower side of the outer tank 120 to wash, After rinsing and dehydration, drainage means 140 for simultaneously discharging the washing water contained in the plurality of inner tanks 111 and 112 or discharging the contaminated washing water contained in any one inner tank and one side of the inner tank 111 and 112. Installed in each of the opening and closing Inner doors 113 and 115 for preventing separation of laundry contained in 111 and 112, and outer doors 41 and 43 that are hinged to an upper side of the outer case 40 to open and close openings for taking out and inserting laundry. consist of.

On the other hand, one side of the outer tank 120 is provided with a circulation pumping means 150 for moving the wash water accommodated in any one of the inner tank (111, 112) to the remaining inner tank.

The driving means 160 is installed on one side of the outer tub 120 to generate power, and is installed on one side of the motor 19 to transmit the rotational force of the motor 19 to the plurality of A belt 21 and a pulley 23 for rotating the inner and outer tanks 111 and 112 forward and backward.

The plurality of inner tubs 111 and 112 are connected to the drive shaft 117 connected to the pulley 23 in series to rotate simultaneously.

The water supply means 130 is composed of a water supply hose (133, 135) for supplying the water supplied from the water supply source into the partitioned outer tank 120, and a water supply valve (131) for opening and closing the water supply hose (133, 135), The drainage means 140 includes drain hoses 141 and 143 for draining the contaminated wash water contained inside the partitioned outer tank 120, and to discharge the water drained through the drain hoses 141 and 143 to the outside. It consists of a drain pump 145 for pumping operation.

The circulation pumping means 150 includes a casing 151, a plurality of impellers 154 and 155 installed to rotate forward and reverse with the drive shaft 153 of the motor 152 coaxially within the casing 151, and the It consists of a plurality of circulation hoses (156, 157, 158, 159) installed on both sides of the casing (151) so that water flows in and out by the rotational force of the impeller (154, 155).

The water supply hoses 133 and 135, the drain hoses 141 and 143, and the circulation hoses 156, 157, 158 and 159 are elastically coupled to allow vibration absorption.

Reference numeral 37 denotes a spring for supporting the upper side of the outer tub 120 so as to absorb vibration, and reference numeral 39 denotes a damper for supporting the lower side of the outer tub 120 and reducing vibration at the same time. , 45 and 47 denote gaskets which prevent the wash water from leaking to the outside.

Next will be described the operation of the drum washing machine having a separate washing function according to an embodiment of the present invention.

First, when the user separates the laundry according to color or quality and puts it in the plurality of inner tanks 111 and 112, closes the inner tank doors 113 and 115 and the outer case doors 41 and 43, and selects an operating condition. Is opened and tap water is supplied to the respective inner tanks 111 and 112 by a plurality of feed hoses 133 and 135.

When tap water is supplied to each of the inner tanks 111 and 112 as described above, the plurality of inner tanks 111 and 112 are simultaneously rotated forward through the belt 21 and the pulley 23 which are driven by the motor 19 to be interlocked with the motor 19. Or perform the washing and rinsing stroke while rotating in reverse.

At this time, the laundry is pulled up to a certain height by a lifter (not shown) installed on the inner side of the plurality of inner tanks 111 and 112, and the laundry is dropped to the bottom of the plurality of inner tanks 111 and 112 by gravity at the predetermined height. Mechanical washing is performed by dropping laundry.

When the washing and rinsing process is completed as described above, a drain valve (not shown) is opened to contaminated water after the washing process is drained through the drain hoses 141 and 143, respectively, and the water drained through the drain hoses 141 and 143. Is pumped by the drain pump 145 and discharged to the outside.

After the washing and rinsing process is completed in the same principle as described above, power is transmitted to the belt 21 and the pulley 23 as the motor 19 rotates at a high speed in one direction so that the plurality of inner tanks 111 and 112 simultaneously move in one direction. Rotation at high speed, the water absorbed by the laundry by the centrifugal force according to the high-speed rotation of the plurality of inner tank (111, 112) exits through the outer tank 120 through the dehydration hole of the inner tank (111, 112) and then one side of the outer tank 120 Drained through the drain hoses (141, 143) installed in, the water drained through the drain hose (141, 143) is pumped by the drain pump 145 is discharged to the outside.

On the other hand, when it is not necessary to separate the wash water, when the user selects a separate operation condition, the water is supplied to one of the inner tanks 111 of the plurality of inner tanks 111 and 112 by the operation of the water supply valve 131, and the motor 19 Power is transmitted by the belt 21 and the pulley 23 by the driving of the drive shaft 117 is rotated, and as the drive shaft 117 is rotated the inner tub 111 is rotated at the same time the inner tub 111 Wash the laundry accommodated in. At this time, the inner tank 112 is also rotated together.

After washing the laundry accommodated in the inner tank 111 as described above, the impeller (154) is rotated forward by the circulating pumping means 150, that is, the motor 152 is rotated forward (rotated in the solid arrow direction). 154) the suction water pressure generated on the inner tank 111 passes through the circulation hose 156 and the casing 151 along the solid arrow direction and then passes through the circulation hose 157. To 112).

When the wash water is moved to the inner tank 112 as described above, the laundry contained in the inner tank 112 is washed as the inner tank 112 is rotated forward and reverse according to the operation principle as described above. In this case, too, the inner tank 111 is, of course, reverse rotation.

In the rinsing process, the washing water is moved on the principle described above to perform a rinsing operation.

In addition, when water is supplied to the inner tank 112, as the motor 152 reversely rotates (rotates in the direction of the dotted arrow), the impeller 155 reversely rotates, so that an intake discharge pressure is generated on the impeller 155 side. Thus, the wash water accommodated in the inner tank 112 passes through the circulation hose 159 and the casing 151 along the dotted arrow direction and is moved to the inner tank 111 through the circulation hose 158.

According to the drum washing machine according to the present invention as described above, a plurality of inner tanks are installed in the washing machine, and as the plurality of inner tanks are rotated at the same time, the laundry can be separated and washed at once according to quality or color, and the laundry can be washed at once. If the separation of water does not need to be circulated again to use the water used in the inner tank has the advantage of reducing the water consumption by more than half.
