Description

Sewing machine for washing machine

The present invention relates to the field of washing machines, and more particularly, to a seams collecting device of the washing machine.

In general, a washing machine is a device that separates stains on laundry by a complex action such as water flow, friction between laundry, and emulsification of detergents. Washing is performed automatically or semi-automatically while repeating the drainage-dehydration stroke several times.

An example of a washing machine having the above function will be described in detail with reference to FIG. 1.

An outer case 1 constituting an outer shape, an outer tub 2 fixedly installed inside the outer case and storing wash water, an inner tub 3 rotatably installed in the outer tub, and the inner tub A pulsator (4) rotatably installed on the bottom surface of the pulsator (4) for generating a flow force in the washing or rinsing water, and a drive motor (5) installed outside the tub (2) to generate rotational power; And a clutch 6 for selectively transmitting the power of the drive motor to the inner tub 3 and the pulsator 4, and the like.

Therefore, if the power is applied while the laundry is in the device, the load of the laundry is sensed by the control of the microcomputer (not shown), and the appropriate level and washing time are automatically set. Will proceed.

The washing or rinsing operation during the operation of the device is performed by washing or rinsing due to the flow force of the washing water or the rinsing water and the emulsification of the detergent as the pulsator 4 rotates left and right by the power of the driving motor 5. Will be performed.

For reference, depending on the washing machine, the inner tub 3 rotates only the pulsator 4 in a stopped state during washing or rinsing, and simultaneously rotates the inner tub 3 and the pulsator 4 at the same time. There are two ways to do this.

The drainage stroke is a process in which only the drain valve 7 is opened while the inner tub 3 and the pulsator 4 are stopped to discharge the washing water or the rinsing water in the out tub 2 to the outside of the apparatus.

The dehydration stroke is a process of removing water from the laundry by centrifugal force by rotating the inner tub 3 and the pulsator 4 in the same direction by the one-way rotational power of the driving motor 5.

Meanwhile, a pumping flow path 8 is formed in the inner tub 3 to pump washing water or rinsing water (hereinafter referred to as “water”) located below the inner tub to the upper portion of the inner tub 3. At the outlet located at the upper side, a seams gathering device is installed for collecting the debris contained in the pumped water or the seams separated from the laundry.

The conventional seams collecting device is composed of a collecting port (9) provided with a collecting net (9a) and the body (10) for fixing the collecting portion to collect foreign substances contained in water as shown in FIG.

Therefore, when the pulsator 4 is rotated, water rises and flows along the pumping flow path 8 by the rotational force of the lower blade 4b formed at the lower part of the pulsator, and the rising water is installed at the outlet side of the pumping flow path. As it passes through the seams gathering device again into the inner tub (3), foreign matters are filtered out and two effects of improving washing power due to the drop of water are obtained.

However, the conventional seams collecting device as described above is installed on the upper portion of the pumping flow path (8), so the amount of pumped water at a high water level is relatively good, but the collecting efficiency is relatively good, but at a low water level, the amount of water to be pumped is reduced. There was a problem of poor efficiency.

In order to prevent the collection efficiency from being lowered in this way, the pulsator 4 should be rotated at a higher speed than when the water level is high. In this case, the output of the driving motor 5, which is the power source of the pulsator 4, must be excessively increased. It is a technology that is difficult to apply in practice because noise and power consumption may increase, as well as overloading may cause equipment failure or shorten the life of components.

The present invention has been made to solve the conventional problems as described above, the object is to lower the position of the seams collecting device to facilitate seams collection even at low water level.

Another object of the present invention is to prevent the fall of the washing efficiency by causing the waterfall flow occurs even if the position of the seam collecting device is adjusted downward.

The present invention for achieving the above object is a washing machine having an inner tub rotatably installed in the outer tub, and a pulsator rotatably installed in the lower portion of the inner tub; Body fixedly installed in the inner lower portion of the inner tub, and detachably coupled to the body, the inlet water is formed so that the water in the inner tub flows into the left / right side and the lower portion, the drain for discharging the introduced water in the front Is formed, the drain is composed of a collecting net is attached to the collecting net for collecting the foreign matter contained in the drained water, the water flowing in the left / right turn of the pulsator or the inner tub to the left / right inlet of the collector The water flowing by the upper wing of the pulsator is introduced into the lower inlet, respectively, and the introduced water is discharged into the inner tub through the drain hole formed in front of the collection chamber, and the foreign matter contained in the discharged water is collected by the collection network. It is to provide a seams collecting device of the washing machine characterized in that the collection.

Another object of the present invention for achieving the above object is a washing machine having an inner tub rotatably installed in the outer tub, and a pulsator rotatably installed at the lower portion of the inner tub and having upper and lower wings respectively formed on upper and lower surfaces thereof. To; It is fixedly installed on the inner lower portion of the inner tub, the lower body is formed in the inlet and the upper drain, respectively, is detachably installed between the inlet and the drain of the body, the water is introduced into the rear through the inlet of the body A water inlet is formed, and in the front, a water outlet for discharging water introduced through the water inlet in the direction of the center of the inner tub is formed, and the water outlet has a collecting net equipped with a collecting net for collecting foreign substances contained in the drained water.

In addition, although the body 100 and the inner tub 3 are primarily coupled by a hook, the body 100 and the inner tub 3 are fastened by a fastening member such as a screw 11 for a firm fixing force.

On the other hand, the collection port 90 detachably coupled to the body 100 has a collection chamber 91 formed therein, the left / right side and the lower portion of the inner tub (3) in the collection chamber 91 Water inlets 91d, 91e, 91f are formed so that water flows in, and water outlets 91g, 91h, 91i for discharging water introduced into the collection chamber 91 in front of the collector 90 are formed. Are each formed, and the drain is provided as a collecting network 92 for collecting foreign matter contained in the drained water.

The collection chamber 91 is divided into the left and right collection chambers 91a and 91b and the lower collection chamber 91c when the collection port 90 is viewed from the front, so that water flowing in each direction does not mix with each other. Each was allowed to flow in and out.

The reason why the water flowing into each collection chamber is not mixed in the above is because the flow direction of the incoming water is different, so if the collection chamber is one, the incoming water collides and vortices are generated in the collection chamber, so that the smooth inflow and drainage of the water is achieved. Because I do not lose.

In addition, the left / right inlet (91d) (91e) is formed with a grate-shaped rib 93 to prevent the laundry and buttons, such as during the washing and rinsing run flow into the collection chamber (91).

The collector 90 is to form a hook on one side of the collector or the body 100 to facilitate attachment and detachment from the body 100, and to form a locking jaw on the side opposite to the hook to be coupled to each other, In this embodiment, the hook 94 is formed on the upper end of the collecting port 90, and the locking jaw 103 is formed on the body 100 opposite thereto.

In addition, the lower end of the collecting port 90 to form a locking projection 95, the body 100 to form a locking groove 104 so that the locking projection 95 is fitted, the upper portion of the collecting port 90 The lower portion by the hook 94 was to be fixed to the body 100 by a locking projection (95).

The coupling structure of the seams collecting device of the first embodiment configured as described above is fixed to the hook 102 formed on the rear surface of the body 100 at an inner lower proper position of the inner tub 3 and then fixed to maintain a firm fixing force. The body 100 is fastened to the inner tub 3 using the above screw 11.

Thereafter, the upper end of the collecting port 90 in a state in which the engaging projection 95 formed at the lower end of the collecting hole 90 is inserted into and supported by the locking groove 104 formed below the insertion portion 101 of the body 100. When pushed toward the body 100, the hook 94 formed at the top of the collector 90 is locked to the locking jaw 103 of the body 100 formed at a position opposite thereto, so that the collector and the body are connected to the fastening force of the hook. It becomes the state joined by.

When the washing machine is operated while the collecting port 90 and the body 100 are coupled as described above, the water located near the pulsator is rotated as the pulsator 4 is rotated to the left / right by the power of the driving motor 5. Flowing in the direction of the centrifugal force of the pulsator flows into the lower collecting chamber (91c) through the water inlet (91f) formed in the lower portion of the collecting port 90, the introduced water is discharged through the drain opening (91i) formed in front of it.

At this time, since the collecting net 92 is installed in the drain hole 91i of the lower collecting chamber 91c, foreign substances contained in the drained water are filtered by the collecting net 92 and collected in the lower collecting chamber 91C. .

Further, the water flowing in the left / right direction by the left / right rotational force of the pulsator 4 is obtained in each of the inlets 91d and 91e of the left collecting chamber 91a and the right collecting chamber 91b of the collecting hole 90. Are respectively introduced into the chamber, and the water introduced into each chamber is discharged through the drains 91g and 91h respectively formed in front of the chamber.

At this time, since the collecting network 92 is provided in each of the drain holes 91g and 91h, foreign matter contained in the drained water is collected by the collecting network and collected in the left and right collecting chambers 91a and 91b.

In particular, the foreign matter collecting device of the shape of each of the collection chamber is partitioned as described above can be used efficiently when applied to the outgoing tub-type washing machine.

Because the inner tub 3 rotates alternately in the left / right direction, the seam collecting device attached to the inner surface of the inner tub 3 also rotates in the same direction, so that water naturally flows into the left / right collecting chambers 91a and 91b. You can improve your sex.

In addition, since the water introduced into each chamber is drained toward the center of the inner tub 3, it generates another stream of water besides the existing stream of water due to the rotation of the pulsator 4, thereby obtaining a secondary effect of doubling the washing force. .

Next, with reference to Figures 5a to 5b will be described in detail with respect to the second embodiment of the present foreign matter collecting device as follows.

The gist of the seams collecting device of the second embodiment allows the water pumped by the upper blades 4a or the lower blades 4b of the pulsator 4 to be introduced from the lower portion of the seams collecting device so as to filter out foreign substances. The rest is configured to satisfy the two effects at the same time by raising along the body 120 to be discharged to the outside by filtering the foreign matter and improving the washing power using a drop of water.
