Description

Device for collecting lint in washing machine

The present invention relates to a washing machine, and more particularly, to a foreign matter collecting device for a washing machine for effectively collecting foreign matters such as lint and the like contained in the washing water circulated in the washing water circulation type washing machine.

The washing machine is a device that exfoliates contaminants by applying energy such as impact to laundry, and may be divided into a pulsator washing machine, a drum washing machine, and an agitator washing machine according to a method of applying energy to laundry. That is, the laundry is impacted by a pulsator or agitator, or the laundry is dropped by dropping the laundry by the rotation of the drum to wash the laundry. And the action of the detergent is added to this is done washing. That is, the above washing machine is a method of washing laundry by giving a shock to the laundry in a mechanical manner.

However, the conventional washing machine mainly washes using mechanical energy such as a pulsator or agitator, and thus it is difficult to avoid twisting or damaging the laundry since a rotational force of a predetermined speed or more is required to satisfy the required washing degree. In addition, since the conventional pulsator washing machine operates in a state in which the inner and outer tanks are filled with water, the amount of washing water used in washing and the amount of detergent are increased, and the overall washing is increased by an increase in the water supply and drainage time regardless of the washing time. There was a problem that the time increases.

Therefore, in order to solve this problem, a washing water circulation type washing machine has been proposed. That is, the washing water is circulated to the inner tank at the time of washing or rinsing, and the circulated washing water is sprayed to the laundry of the inner tank. In this manner, since only a small amount of washing water may be supplied to the inner tank and the outer tank, the above-described problems may be solved to some extent.

Referring to Figure 1, a conventional washing water circulation washing machine will be described.

An inner tub 3 for storing the washing water is installed in the washing machine case 1, and an inner tub 5 in which a plurality of through holes 5a are formed is rotatably installed in the tub 3. The pulsator 7 is rotatably installed in the inside of (5). And the inner tank 5 and the pulsator 7 are rotated by the drive means 9 provided in the bottom face of the outer tank 3.

Meanwhile, a drain duct 11 for discharging the washing water to the outside of the washing machine is connected to the bottom of the outer tub 3, and a drain valve 13 is installed at a predetermined position of the drain duct 11. In addition, a circulation duct 15 for circulating the washing water into the inner tank 5 is branched at a predetermined position of the drain duct 11, and a circulation pump 20 for pumping the washing water at a predetermined position of the circulation duct 15. Is installed.

Referring to Figure 2, the circulation pump will be described.

The circulation pump 20 is composed of a motor unit 22 generating a rotational force and an impeller unit 24 coupled to the motor unit 22 and installed on the circulation duct 15 to pump washing water. do. That is, the wash water from the outer tank is introduced into the impeller 24 of the circulation pump 20, the introduced wash water is pumped, so that the wash water is discharged to the inner tank again.

The operation of the washing machine described above with reference to FIGS. 1 and 2 is as follows.

The operation of the washing machine may be divided into a washing stroke, a rinsing stroke, and a dehydrating stroke. Each of the above modes is sequentially performed to perform washing.

First, the laundry administration will be described. When the laundry is put into the inner tank 5 and the washing machine is operated, the washing water is supplied to the inner tank 5, and the washing water fills the inner tank 5 and the outer tank 3 to a predetermined level. When the water supply is completed, the pulsator 7 washes the laundry while rotating forward and reverse. At this time, the circulation pump 20 is also driven to wash water is discharged back to the inner tank.

After the washing operation is performed for a predetermined time, the drain valve 13 is opened to discharge the contaminated washing water to the outside. Thereafter, clean washing water is supplied to the inner tank 5, and then the pulsator 7 is rotated to perform a rinsing stroke. At this time, the circulation pump 20 is driven so that the wash water is discharged to the inner tank again.

In the dehydration stroke, the inner tank 5 and the pulsator 7 rotate together at high speed in one direction. Therefore, the washing water of the inner tank 5 is discharged to the outer tank 3 through the through hole 5a by centrifugal force. At this time, since the circulation pump 20 is stopped and the drain valve 13 is open, the washing water discharged to the outer tank 3 is discharged to the outside of the washing machine through the drain valve 13.

However, the conventional laundry water circulation washing machine described above has the following problems.

First, in the conventional washing machine, foreign matter such as lint and soil in the washing rinsing or rinsing cycle is circulated along the circulation duct 15 as it is. Accordingly, this foreign matter is wound around the impeller 24 of the circulation pump 20, in particular, the connecting portion 24a of the impeller 24 and the motor portion, which may constrain the circulation pump 20. In addition, when foreign matters such as buttons separated from clothes and the like circulate intact, there is a concern that these may cause a failure of the circulation pump 20.

Second, in order to solve the above problems, it is conceivable to install a filter for filtering foreign matters on the circulation duct 15, but in this case, although foreign matters can be filtered to some extent, it causes inconvenience to users. That is, in the case of using a mesh filter that is commonly used, even if the foreign matter is filtered during the washing or rinsing stroke, the filtered foreign matter is attached to the filter as it is. Therefore, after using the washing machine for a predetermined time, the filtration performance of the filter is lowered, and there is a problem that the user has to remove foreign substances attached to the filter, which is very inconvenient.

The present invention has been made to solve the above problems, an object of the present invention is to collect the foreign matter for a washing machine that can be circulated only pure wash water by filtering the foreign matter contained in the wash water on the circulation duct in the washing water circulation type washing machine To provide.

Another object of the present invention is to provide a foreign matter collecting device for a washing machine capable of automatically discharging the filtered foreign matter.

At this time, the drainage duct (11a, 11b) is in communication with one side of the cyclone body 110, the incoming drainage duct (11a) that the wash water containing foreign matter, such as lint, and the foreign matter dust collector 150 in communication with When the drain valve (not shown) is opened, the foreign matter is divided into a discharge drain duct (11b) discharged to the outside with the wash water. A predetermined position of the circulation duct 15 is provided with a circulation pump 20 for forced circulation of the wash water.

On the other hand, the cyclone body 110 is made of a cylindrical shape so that the foreign matter is rotated along the inner wall by the centrifugal force is separated, the inlet drainage duct into which one side (left side in the drawing) the wash water containing the foreign matter ( 11a) is installed to communicate with the inside, and the other side (right side in the drawing) is provided with a circulation duct 15 for discharging only pure wash water from which foreign matters are separated and communicated with the inside. In addition, the outer peripheral edge of the other side of the cyclone body 110 is provided with a foreign material discharge pipe 112 for guiding the foreign matter separated from the wash water to the foreign material dust collecting container 150, the foreign material discharge pipe is a cyclone for the smooth discharge of the foreign material It is preferable that the body 110 is formed in a tangential direction.

As shown in FIG. 4, a swirl flow generating means 120 is provided between the one side and the other side of the cyclone body 110 to pivot the wash water introduced through the inlet drainage duct 11a. A high specific gravity material reservoir 130 is provided at the rear end of the swirl flow generating means. At this time, the high specific gravity material reservoir 130 may be provided at the front end portion of the swirl flow generating means 120, but after the swirl flow generating means for smooth discharge of the high specific gravity material 200 to be described later It is preferably installed at the end. In addition, the foreign matter dust collector 150 is provided to communicate with each other through the foreign matter discharge pipe 112 in the lower portion of the cyclone body 110, so that the foreign matter passing through the cyclone body can be smoothly collected by its own weight.

The high specific weight material storage container 130 is in communication with the cyclone body 110, it is preferable that the high specific weight material 200 is provided on the upper portion of the cyclone body by the magnetic weight toward the cyclone body side. At this time, the high specific gravity material reservoir 130 has a cylindrical tube portion 132 is formed in the lower portion of the cylindrical body to reduce the cross-sectional area to facilitate the discharge of the high specific gravity material 200, the cyclone body at the bottom of the cylindrical tube portion A high specific weight material outlet 134 is formed in communication with 110. In addition, between the high specific weight material outlet 134 and the cyclone body 110 is provided with a high specific material discharge means 140 for discharging the high specific material 200 only when the wash water is introduced.

As shown in Figure 5a, the high specific weight material discharging means 140 in the longitudinal direction of the cyclone body on the outer periphery of the cyclone body to open and close the high specific material storage bin and the cyclone body according to the inflow of wash water It is an impeller consisting of a shaft 142 is installed as a plurality, and a plurality of wings 144 rotatably installed on the shaft. That is, the wing 144 of the impeller is rotated by the turning force of the washing water or foreign matter that rotates along the inner wall of the cyclone body to discharge the foreign matter in the high specific gravity material outlet during rotation into the interior of the cyclone body.

To this end, the impeller wing 144 is preferably curved so that it rotates well by the rotating washing water, regardless of the number.

When the high specific gravity material storage container 130 configured as described above is provided at the rear end of the swirl flow generating means 120, the action of the high specific gravity material discharge means 140 may be ensured by the wash water past the swirl flow generating means. Can be. That is, the washing water passing through the swirl flow generating means 120 is rotated by hitting the wing 144 of the impeller provided on one side of the cyclone body while turning along the inner wall of the cyclone body 110. Accordingly, the high specific gravity material 200 is discharged only when the wash water flows into the cyclone body 110.

On the other hand, the high specific-weight material discharge means 140 is provided in the direction of the axis of the impeller orthogonal to the longitudinal direction of the cyclone body, it may be provided with a wing in the radial direction of the axis.

On the other hand, the high specific gravity material 200 is to agglomerate foreign matter, such as lint, seams and fine particles separated in the washing process included in the wash water, when the wash water passes the cyclone body 110 by the centrifugal force The material having a specific gravity greater than water having a specific gravity of 1 may be separated from the wash water.

Specifically, the high specific gravity material 200 is mixed with the foreign matter contained in the wash water to increase its total weight, thereby increasing the centrifugal force due to the turning force of the wash water to facilitate the separation of the foreign matter by the cyclone method. That is, the centrifugal force is proportional to the mass. When the high specific gravity material 200 is mixed with foreign matter such as lint, the total mass is increased to increase the centrifugal force. In this case, the foreign matter is pushed toward the inner wall side from the center of the cyclone body 110 under the influence of the centrifugal force, and is discharged to the foreign matter outlet 112 while turning the inner wall along the running direction of the wash water.

Therefore, the high specific gravity material 200 is preferably made of metal powder for smooth discharge from the specific gravity side and the high specific weight storage container 130, in particular made of magnetite (magnetite) to increase the cohesion with foreign matters Do.

On the other hand, the shape of the high specific weight material storage container 130 is also not necessarily limited to the cylindrical shape, and is in communication with the cyclone body 110 by the storage of high specific material and the high specific material discharge means 140, such as the impeller. Any shape can be applied.

On the other hand, from one side of the cyclone body 110 to the front end portion of the swirl flow generating means 120 is formed an expansion section 114 is increased in cross-sectional area along the inflow direction of the wash water. That is, the cyclone body 110 is a cylindrical shape having one side conical. This is to add the turning force by allowing the washing water introduced into the cyclone body to pass evenly through the swirl flow generating means.

As shown in FIG. 5B, the swirl flow generating means 120 includes a shaft 122 formed in a direction parallel to the longitudinal direction of the cyclone body, and a plurality of axial blades 124 radially formed on the outer periphery of the shaft. Is done.

Therefore, the wash water passing through the swirl flow generating means 120 has a swirl force while flowing along the curved surface of the axial blade 124 to rotate along the inner wall of the cyclone body.

On the other hand, the swirl flow generating means 120 is a known technique for applying a swirl force to the internal flow in the cyclone dust collector, it is possible to apply a modified form, such as having a spiral blade instead of the axial blade.

Referring to the overall operation of the foreign matter collecting device for a washing machine configured as described above are as follows.

Figure 6 is a cross-sectional view showing the action of the washing water circulation washing machine according to the present invention, will be described divided into washing and rinsing administration and dehydration administration.

First, during washing and rinsing stroke, the drain valve (not shown) provided in the discharge drain duct 11b is closed and the circulation pump 20 is in a driving state. Therefore, the washing water in the outer tank (3) is repeated through the inlet drainage duct (11a), the cyclone body 110 and the circulation duct 15 by the circulation pump in order to repeat the circulation process flowing back into the inner tank. At this time, the wash water is passed through the cyclone body 110 before entering the circulation duct 15, where the foreign matter is separated and only the pure wash water is introduced into the circulation duct 15. Therefore, it is possible to prevent the operation of the circulation pump 20 to be constrained by foreign matter.

In detail, the washing water in the outer tub 3 is introduced into the cyclone body 110 through the inlet drainage duct 11a and flows while turning inside the cyclone body after passing the swirl flow generating means 120. . At this time, as the wing of the impeller 140 is rotated by the rotating washing water, the high specific weight material 200 in the high specific material storage container 130 is introduced into the cyclone body through the discharge pipe 134. Subsequently, the high specific gravity material 200 introduced into the cyclone body 110 generates a mixture 300 that is heavier than water while mixing with the foreign matter contained in the wash water, and the mixture 300 of the foreign matter and the high specific gravity material 300. ) Is finally collected through the foreign matter outlet 112 through the foreign matter outlet 112 while turning along the inner wall of the cyclone body 110 by centrifugal force. In addition, the pure wash water from which the foreign matter is separated is introduced into the circulation duct 15 by the suction force of the circulation pump 20 and is re-injected into the inner tank. At this time, since the drain valve maintains the closed state, the mixture 300 of the foreign matter and the high specific gravity material is continuously collected in the foreign matter dust collecting container 150.

Next, during the dehydration stroke, the circulation pump 20 is in a stopped state and the drain valve is in an open state. Thus, the wash water in the outer tub 3 is finally discharged to the outside through the drain duct (11a, 11b) and is no longer circulated along the circulation duct (15).

At this time, the washing water introduced into the cyclone body 110 through the inlet drainage duct 11a is flowed into the foreign matter dust collecting container 150 through the foreign matter discharge port 112, and the foreign matter and ferns in the foreign matter dust collecting container continue. The mixture of heavy material 300 is finally discharged to the outside through the discharge drain duct (11b).

That is, the foreign matter separated from the wash water at the washing and rinsing stroke is automatically discharged to the outside by the washing water discharged to the outside during the dehydration stroke. Therefore, it is possible to avoid the hassle of cleaning the foreign matter dust collector 150 arbitrarily.

First, according to the present invention, as the foreign matter contained in the wash water is effectively collected in the foreign matter collecting device, it is possible to prevent foreign matter from being introduced into the circulation pump. Therefore, it is possible to prevent the circulation pump from being confined by the foreign matter.

Second, according to the present invention by filtering the foreign matter contained in the wash water on the circulation duct, only pure wash water can continue to circulate, it is possible to perform effective washing with only a small amount of wash water.

Third, according to the present invention, since the foreign matter collected in the foreign matter collecting device is automatically discharged to the outside of the washing machine at the time of dehydration administration, there is no need to clean the foreign matter collecting device regularly, thereby providing convenience for use.
