Description

Foam Dispenser of Drum Washing Machine

The present invention relates to a drum washing machine, and more particularly, to a drum washing machine which can prevent a load on a motor for rotating a dehydrating drum by easily discharging bubbles generated between a washing tank and a dehydrating drum to the outside during an intermittent dehydration process. It relates to a bubble discharge device.

The structure of a conventional drum washing machine is shown in FIG.

That is, a washing tank 2 coupled to the inside of the drum washing machine 1 to store the washing water, and a dehydrating drum coupled to the washing tank 2 to rotate with the rotational force of the motor and wash and rinse and dehydrate the laundry ( 3), a water supply hose 4 for supplying the wash water into the dehydration drum 3, a reservoir 5 for collecting the wash water to discharge the wash water supplied to the water hose 4 to the outside; And a drain pump 6 for discharging the wash water collected by the water storage unit 5 to the outside, and a drain hose 7 for guiding the wash water discharged to the drain pump 6 to the outside.

Referring to the operation of the drum washing machine 1 according to the configuration as described above are as follows.

First, the operation of the drum washing machine 1 is an intermittent dehydration process in the middle of ending the washing process and repeating the rinsing process.

And, the intermittent dehydration process is a process for improving the rinsing performance by removing the detergent component contained in the laundry.

In this case, when the intermittent dehydration process is carried out, the detergent component contained in the laundry hits the washing tank 2 by the rotation of the dehydration drum which rotates at high speed, and bubbles are generated.

Then, the wash water is supplied to the water supply hose 4 to remove the foam, and the wash water and the foam collected in the water storage unit 5 are discharged to the outside by operating the drain pump 6.

However, in the intermittent dehydration process, the dehydration drum 3 rotates at a high speed, so that a large amount of bubbles are generated.

In addition, the large amount of foam is blown between the washing tank 2 and the dehydrating drum 3 so as not to be discharged together with the washing water supplied to the water supply hose 4.

In addition, the bubbles stuck between the washing tank 2 and the dehydration drum 3 will rotate together with the dehydration drum 3.

As the dehydrating drum 3 and the foam rotate together, the frictional force between the washing tank 2 and the dehydrating drum 3 increases with the foam.

Therefore, a problem occurs that the motor that rotates the dehydration drum 3 is overloaded due to a large amount of foam.

In addition, since the motor is overloaded, the normal rotation speed at the time of intermittent dehydration cannot be output.

In addition, when the motor is severely overloaded, the motor may be damaged and the drum washing machine 1 may not be used.

In addition, a large amount of washing water was consumed by supplying the washing water several times to remove the large amount of foam.

Further, by repeating the process for removing the large amount of bubbles several times, the power for operating the drum washing machine 1 also consumes a large amount.

In the intermittent dehydration process, a large amount of foam generated between the washing tank and the dehydration drum is discharged to the outside to prevent the motor from being overloaded and to shorten the washing time to save water and detergent. to provide.

In order to achieve the above object, the present invention can achieve the object of the present invention by combining the bubble guide to guide the bubble collected in the reservoir to the drainage pump.

The configuration of the drum washing machine 101 of the present invention is shown in Figs.

That is, during the intermittent dehydration process of the drum washing machine 101, the frictional force of the dehydration drum 103 is increased by the foam generated between the washing tank 102 and the dehydration drum 103 to prevent the motor from being overloaded. In order to guide the bubbles collected in the reservoir 105 in the intermittent dehydration process in the direction of the drain pump 106 is configured to have a bubble guide (111) coupled to the reservoir 105.

In addition, the bubble guide 111 is formed in the insert 112 and the insert 112 for coupling the bubble guide 111 to the reservoir 105, the foam dehydration drum 103 It was provided with an elastic rib 114 to be guided only in the direction of the drain pump 106 without rotating along.

At this time, the bubble guide 111 has a coupling groove 108 formed on one side of the reservoir 105 in order to couple the insert 112 to the reservoir 105.

In addition, in order to prevent the insert 112 of the foam guide 111 from being detached from the coupling groove 108 of the reservoir 105, the outer inclined surface 116 formed on the outer surface of the insert 112 and In addition, the inner inclined surface 109 formed in the coupling groove 108 of the reservoir 105 so as to match the outer inclined surface 116 was further provided.

In addition, the elastic rib 114 of the bubble guide 111 is further provided with a plurality of grooves 115 through which the wash water can pass in order to minimize the rotational friction of the dehydration drum 103.

In addition, a plurality of brushes 113 are implanted instead of the elastic ribs 114 formed on the insert 112 of the foam guide 111.

In addition, the elastic ribs 114 and the brush 113 are angled in a direction toward the reservoir 105 inside a connection line (not shown) connecting the rotation center of the dehydration drum 103 and the insert 112. It is formed to be inclined at an inclination angle of, so that the bubbles collected in the reservoir 105 is easily guided to the drain pump 106.

Referring to the effects of the configuration as described above are as follows.

First, the detergent contained in the laundry during intermittent dehydration of the drum washing machine 101 hits the washing tub 102 due to the high speed rotation of the dehydrating drum 103 and generates bubbles.

Then, in order to remove the bubbles generated by hitting the washing tank 102, the washing water is supplied to the water supply hose 104 and the drain pump 106 is operated.

In addition, the foam is rotated with the wash water supplied by the water supply hose 104 between the washing tub 102 and the dehydration drum 103.

At this time, the washing water and the foam that was rotated between the washing tank 102 and the dehydration drum 103 hit the bubble guide 111 coupled to the reservoir 105.

In addition, the wash water and the foam that hit the bubble guide 111 is guided to the reservoir 105 by the guide of the bubble guide (111).

That is, as shown in FIG. 2, the foam flowing with the wash water collides with the foam guide 111 combined with the insert 112 into the coupling groove 108 of the reservoir 105.

At this time, the plurality of grooves 115 are formed in the elastic ribs 114 formed on the insert 112, thereby reducing the frictional force with the washing water rotating together with the dehydration drum 103 and foaming into the drain pump 106. Will guide you.

Therefore, the washing water that rotates together with the dehydration drum 103 to the groove 115 between the elastic ribs 114 passes and the foam strikes the elastic ribs 114.

And, the bubble hit the elastic rib 114 is lost to the adhesion to the dehydration drum 103 is guided to the reservoir 105 by the guide of the bubble guide 111.

At this time, the bubble guide 111 is coupled to contact with the dehydration drum 103 or in close contact with the short distance to reliably remove the bubble from the dehydration drum 103 to guide in the direction of the drain pump 106 will be. That is, the foam is formed in a predetermined size or more than the diameter of the groove 115 is not easy to pass through the groove 115, wash water to facilitate the passage of the groove 115. Accordingly, by passing through the groove 115 of the wash water during the bubble removal operation of the bubble guide 111, it is possible to reduce the rotational friction force during the bubble removal operation of the bubble guide 111.

The bubble guide 111 is more reliably and easily coupled to the reservoir 105 with a predetermined inclination angle α opposite to the rotational direction with respect to the normal line connected to the rotation center of the dehydration drum 103. You will be able to guide the bubble.

In addition, the bubble guide 111 is because the outer inclined surface 116 formed in the insert 112 is inserted into the inner inclined surface 109 of the coupling groove 108 formed in the reservoir 105, the coupling groove 108 From the bubble guide 111 is to be prevented from being separated.

Then, the bubbles hit the bubble guide 111 dropped into the reservoir 105 is discharged to the outside by the drain pump 106 together with the wash water.

At this time, the foam between the dehydration drum 103 and the washing tank 102 is discharged to the outside so that the friction force due to the foam is not generated during the high-speed rotation of the dehydration drum 103.

In addition, the foam is discharged to the outside, so that the rotational friction force of the dehydration drum 103 is normal so that the load on the motor for rotating the dehydration drum 103 is not applied.

In addition, since the load is not applied to the motor, the rotation speed of the motor can be normally output during intermittent dehydration.

5 and 6 can achieve the object of the present invention by implanting a plurality of brushes 113 instead of the elastic ribs 114 on the insert 112 of the foam guide 111. Will be.

That is, the bubbles gathered by the reservoir 105 are bumped into the plurality of brushes 113 implanted on the insert 112 of the foam guide 111 to be guided to the drain pump 106.

In addition, the foam guide 111 in which the plurality of brushes 113 are implanted does not affect the rotation of the dehydration drum 103 by passing the wash water between the brushes 113 and the brushes 113.

Therefore, a large amount of bubbles generated during intermittent dehydration of the drum washing machine 101 are simply guided to the drain pump 106 by the bubble guide 111 coupled to the reservoir 105 to be discharged to the outside to the motor. Overload can be prevented.

In addition, the repeated process of supplying and discharging the washing water to remove the large amount of bubbles generated between the washing tank 102 and the dehydration drum 103 is eliminated, thereby shortening the washing time and saving the washing water and power. Will be.

The present invention as described above is coupled to the water guide to the bubble guide for guiding the bubbles collected in the reservoir to the drainage pump to guide the drainage pump to discharge a large amount of bubbles generated between the washing tank and the dehydration drum to the outside during the intermittent dehydration process It is useful to prevent the motor from being overloaded and to shorten the washing time to save water and detergent.
