At this time, the pressing piece 47 is formed to be connected to the locking projection 45 in order to use the elasticity of the locking projection 45.

It will be described that the lint is collected in the prior art having such a configuration.

When washing proceeds while the washing tank 5 and the washing blade 6 rotate, the washing water rotates inside the washing tank 5 to form a stream of water. Rotational water flow is formed in the direction of arrow A in FIG. 1 by the rotation of the washing blade 6 during the water flow. And the lifting and lowering flow which is formed in the arrow B direction in FIG. 1 by the centrifugal force by the rotation of the said washing tank 5 is formed. The lifting and lowering flow of the washing water flows from the lower part to the upper part of the washing tank 5 and then falls to the center of the washing tank 5. And as a whole, the complex water flow is formed while the rotational water flow and the lifting water flow are combined, and washing proceeds.

While the washing is in progress, the lift flows through the collecting device. That is, the lifting and lowering flow falling to the center of the washing tub 5 enters the inside of the collecting device 7 and moves toward the bottom edge of the washing tub 5.

In detail, the washing water flows into the filtering chamber 22 through the inflow hole 43 formed in the cover 40 of the collecting device 7. The washing water introduced into the filtering chamber 22 passes through the collecting network 34, and in this process, lint and seams mixed in the washing water are collected in the collecting network 34. The washing water circulates through the washing tank 5 by passing through the filtering chamber 22 through the discharge hole 24.

However, the prior art as described above has the following problems.

That is, in the collecting device 7 according to the prior art, foreign matters such as lint and the like mixed in the lifting water flow can be collected, but the lint and the mixed water in the rotational water are not collected. In other words, the path through which the wash water flows into the filtering chamber 22 is the inflow hole 43. However, the inflow hole 43 is formed to be opened upward on the upper surface of the cover 40 so that only the lifting flow can be introduced into the inflow hole 43 and the rotational flow is properly inside the inflow hole 43. It cannot be flowed into. Therefore, the collection capacity of the lint is relatively poor, there is a problem that the washing efficiency is lowered.

In addition, the inflow hole 43 into which the washing water is introduced into the filtering chamber 22 is formed only at a portion corresponding to the inside of the insertion rib 42, and thus there is a problem that the amount of the washing water is relatively small.

Therefore, an object of the present invention is to solve the problems of the prior art as described above, it is to be able to collect lint mixed in various water flows formed in the washing tank.

Another object of the present invention is to maximize the inflow area for flowing the wash water into the collection apparatus.

As shown in the figure, a plurality of inflow holes 52 are formed to be opened toward the upper portion of the cover 50 on the upper surface of the cover 50 installed on the top of the fixed case 20. The inlet 52 is formed centrally in the cover 50, a part is formed to the edge of the cover 50. The inlet 52 is formed such that the inlet is wider in cross section than the outlet. This serves to prevent backwashing the water once entering the inlet 52. Through such an inlet hole 52, the lifting water flow which is generally formed in the washing tank 5 is transmitted to the inside of the collecting device.

A plurality of water flow guides 55 are provided on the upper surface of the cover 50. The water flow guide 55 may be integrally formed on the top surface of the cover 50 or may be separately formed and mounted along the edge of the top surface of the cover 50.

As shown in FIG. 3, the water flow guide 55 protrudes the edge of the tip 55L the highest. At this time, the protruding height of the water flow guide 55 should be at least 10 mm. The water flow guide 55 is formed to gradually lower toward the center of the cover 50 at its tip 55L. It is also formed to be inclined downward toward the rear end 55T of the water flow guide 55, and the rear end 55T of the adjacent water flow guide 55 is formed to be connected to each other.

As the water flow guide 55 is formed to protrude on the upper surface of the cover 50 as described above, the water flow guide 55 serves as a kind of washing wing. That is, the collecting device whirls the washing water while rotating together with the washing tub or the washing blade and serves to impact the washing cloth.

One side of the water flow guide 55 is formed with an inlet 56 long to open in the rotational direction of the collecting device. The inlet 56 mainly serves to introduce the rotational water flow into the collection device. Here, the collection device may be rotated forward and backward with the rotation of the washing tank (5) or washing blade (6). Accordingly, the direction of formation of the inlet port 56 is selectively selected from each of the plurality of water flow guides 55 as shown in FIG. 3. In the illustrated embodiment, all four water flow guides 55 are formed, and the front ends 55L of the two water flow guides 55 are formed to face each other.

In addition, a partition wall 57 is formed in a lattice shape at an inlet 56 formed in the water flow guide 55. The partition wall 57 serves to prevent the laundry cloth from being sucked into the collecting device through the inlet 56. In addition, the partition wall 57 is formed narrower as it enters the inlet port 56 to prevent the wash water from flowing back. In addition, the internal flow path of the inlet 56 partitioned by the partition wall 57 is inclined downward from the inlet to the outlet. This is a configuration for guiding the wash water to the filtering chamber 22.

Now look at the configuration of the bottom surface of the cover 50. First, a fastening part 60 for fastening with the fixing case 20 is formed at a position where the bottom edge of the cover 50 is symmetric with each other. And the insertion guide 62 is formed between the fastening portion 60 at the bottom edge of the cover 50. The insertion guide 62 serves to guide the cover 50 to be accurately seated on the fixing case 20.

On the other hand, the inside of the lower surface of the cover 50, the insertion rib 64 which is fitted into the interior of the collecting port 30 is formed. The insertion rib 64 is inserted into the collecting port 30 to prevent the washing water introduced through the inlet 52 or the inlet 56 from leaking out of the filtering chamber 22.

Next, another embodiment of the present invention will be described with reference to FIG. 6. As shown in the figure, a plurality of inflow holes 152 are formed to be opened toward the upper portion of the cover 150 on the upper surface of the cover 150 is installed on the top of the fixed case 20. The inlet hole 152 is formed on the upper surface of the cover 150 is not formed water flow guide 155 to be described below. Through such an inlet hole 152, the lifting water flow which is generally formed in the washing tank 5 is transmitted to the inside of the collecting device. The inlet hole 152 is preferably such that the inlet is formed to have a wider cross-sectional area than the outlet, so that the wash water introduced once does not flow back.

A plurality of water flow guides 155 are provided on the upper surface of the cover 150. The water flow guide 155 may be integrally formed on the upper surface of the cover 150 or may be separately formed and mounted, and a plurality of the water guides 155 are formed so that the edge of the cover 150 is further protruded.

The water flow guide 155 is formed such that the front end 155L is relatively low and the rear end 155T is relatively high. In this case, the surface connecting the rear end 155T from the front end 155L is formed to be inclined, and the inlet 156 for introducing the rotational flow generated in the washing tank 5 into the filtering chamber 22 is punctured. The inlet 156 is formed on the inclined surface to allow the inflow of rotational water into the interior according to the rotation of the collecting device.

Meanwhile, the water flow guides 155 are formed in pairs so that the rear ends 155T face each other in this embodiment. Therefore, the inlet 156 is formed to be opened in the opposite direction to each other in the adjacent water flow guide 155.

The water flow guide 155 is formed to be gradually inclined upward toward the edge from the center of the top surface of the cover 150 so as to protrude from the edge of the cover 150 to be steeply inclined and is connected to the side of the cover 150.

Here, the water flow guide 155 is formed to protrude relatively higher than the upper surface of the cover 150. Therefore, the water flow guide 155 also serves as a kind of washing blade. In other words, the collecting device rotates with the washing blade or the washing tank to form a stream of water and impact the washing cloth.

Now look at the configuration of the bottom of the cover 150. First, fastening portions 160 for fastening with the fixing case 20 are formed at positions where the bottom edges of the cover 150 are symmetric with each other. And the insertion guide 162 is formed between the fastening portion 160 on the bottom edge of the cover 150. The insertion guide 162 serves to guide the cover 150 to be seated correctly on the fixing case 20.

On the other hand, the inner side of the lower cover 150 is formed with an insertion rib (not shown) to be fitted inside the collecting port 30. The insertion rib is inserted into the collecting port 30 to prevent the washing water introduced through the inlet 152 or the inlet 156 from leaking out of the filtering chamber 22.

Therefore, the lift flow is introduced into the collecting device through the inlet 52 to filter lint or foreign matter from the collecting port 30, and the rotating water flow is introduced through the inlet 56 to collect the collecting port 30. ) Lint or foreign material will be filtered out.

At this time, the water flow guide 55 is formed to be opened in the rotational direction of the washing tank 5 or the washing blade 6, and the rotational water flow is formed in accordance with the rotational direction of the washing tank 5 or the washing blade (6) It will flow into the inside of the collecting device.

In addition, the water flow guide 55 has a portion where the inlet port 56 is formed to protrude relatively high, so that washing water flows into the inlet port 56 smoothly.

In this way, the wash water introduced into the collecting device is filtered lint or foreign matter in the collecting network 34 in the interior of the filtering chamber 22, and discharged again to the washing tank 5 to proceed with the washing.

In addition, the water flow guide 55 is formed to protrude relatively high on the surface of the cover 50 to serve as a kind of washing wing. Therefore, while forming the water flow during the washing and at the same time to the impact on the laundry cloth it is possible to obtain a sucking effect. And when the laundry cloth is dropped into the center of the washing tank 5 in a state in which the lifting cloth flows together, the lint and the like mixed with the washing water between them while hanging the laundry cloth.

In the present embodiment, the inlet 56 has a relatively large area at the tip 55L side of the water flow guide 55 which protrudes relatively high, but the partition wall 57 is formed therein to wash the inlet 56. The laundry cloth does not flow into the inside through the carriage inlet 56. In addition, the cross-sectional area of the inlet 56 is gradually narrowed toward the inside by the partition wall 57, thereby preventing backflow of the wash water.

On the other hand, in the embodiment shown in Figure 6, the inlet 156 is formed on the inclined surface of the water flow guide 155, by being rotated with the rotation of the collecting device by this to allow the inflow of the rotational water formed in the washing tank into the inside do.

In this embodiment, the water flow guide 155 is formed to protrude upward on the outer circumferential surface of the cover 150, thereby increasing the washing efficiency while serving as a washing blade during washing.

As described above, according to the present invention, the inlet and the inlet are formed in accordance with the water flow formed in the washing tank so that the wash water flows into the collecting device so that the smooth and large amount of the washing water passes through the collecting device. It is the basic technical idea that the water flow guide of the cover can take on the role of the washing blade to some extent.

Within the scope of the basic technical idea of the present invention, of course, many other modifications are possible to those skilled in the art.
