Description

Drum washing machine provided with a drum having a collector for an extraneous matter}

The present invention relates to a drum washing machine, and more particularly, to a drum washing machine having a drum having a foreign matter collecting device capable of efficiently collecting foreign matter such as lint generated during washing by installing a foreign matter collecting device on the drum. .

The drum washing machine adopts a method of washing laundry by dropping laundry in the drum from top to bottom by rotating the cylindrical drum as a washing tank. For this reason, the drum washing machine has the advantage that the damage of the laundry due to friction or twist between the laundry and the amount of the wash water used is relatively small compared to the general washing machine of the pulsator type.

4 and 5 show the basic structure of the drum washing machine.

The drum washing machine 400 has a water tank 420 installed horizontally inside the main body 410 shown by a dotted line. In addition, a drum 440 serving as a washing tank is rotatably installed in the storage tank 420.

The upper portion of the reservoir 420 is provided with a water supply port 480 for supplying the washing water from the outside to the drum 440, and a part of the water supply port 480 is associated with the detergent container 490 so that the detergent is temporarily supplied when the washing water is supplied. To be supplied. The surface of the drum 440 is formed with a plurality of through holes 441 through which washing water passes.

A driving motor 450 for rotating the drum 440 is installed below the reservoir 420.

In addition, a drain pump 470 is installed at a lower portion of the reservoir 420 to discharge the washed water from the drum 440 to the outside, and a drain pipe 471 connected to the outside at the end of the drain pump 470. ) Is provided.

In addition, a filter 460 is installed between the reservoir 420 and the drain pump 470 for filtering foreign matter such as lint generated during washing included in the wash water.

The front of the main body 410 is provided with a door 430 for opening and closing the drum 440.

In the conventional drum washing machine 400 having such a configuration, foreign matter such as lint generated in the drum 440 during washing is discharged through the plurality of through holes 441 formed in the drum 440, which is a filter 460 and a drain pump. It is filtered through 470 or discharged to the outside.

However, such a conventional drum washing machine has accumulated foreign matter accumulated in the filter when the washing for a long time, or if the accumulation amount is excessive, foreign matter accumulated in the drain pump. For this reason, it was necessary to replace the filter every predetermined period, there was a problem that the impeller installed in the drain pump is damaged by the introduction of foreign matter.

The present invention was devised to solve the above-mentioned problems of the prior art, and an object of the present invention is to install a collection device for collecting foreign matters generated during washing in the drum drums without filter replacement or damage to the drain pump even for a long time washing It is to provide a washing machine.

In order to achieve the above object of the present invention, the present invention is installed in the washing means for washing the laundry and the foreign matter collecting device, characterized in that it comprises a foreign matter collecting means for collecting foreign matters generated during washing A drum washing machine having a drum having the same is provided.

In the present invention, the collecting means is hinged to one end of the collecting container and the collecting container for storing the foreign matter and includes an opening and closing device for opening and closing the collecting container.

In addition, the opening and closing device has a plurality of through holes through which foreign matter penetrates, and the through hole is formed such that the size of the inlet through which the foreign matter flows is larger than the size of the outlet through which the foreign matter flows out.

Hereinafter, with reference to the accompanying drawings will be described in detail a drum washing machine having a drum having a foreign matter collection apparatus according to a preferred embodiment of the present invention.

1 shows a drum having a foreign matter collecting device according to a preferred embodiment of the present invention.

The drum 100 has a cylindrical shape and a plurality of first through holes 101 are formed on the surface thereof, so that the washing water is supplied (discharged) to the drum 100.

One side of the drum 100 is installed in the collecting container 110 in the longitudinal direction. There is no limitation on the size and installation direction of the collecting container 110, but considering that the drum 100 rotates, it is preferable to install to have a suitable length in the longitudinal direction.

The collecting device of the present invention is composed of a collecting container 110 and a cover 120, the collecting container 110 is preferably opened and closed by a cover 120 having the same length. The cover 120 is formed with a plurality of second through holes 121 having a diameter larger than the diameter of the first through holes 101 formed on the surface of the drum 100. Although not limited to the shape of the collector 110 and the lid 120, it is preferable to form so as to have a curvature equal to the outer curvature and the inner curvature of the drum 100, respectively.

The cover 120 is hinged to the drum 100 and the outer part is coupled to the drum 100 so as to be easily opened by the operator at the door side (front in the drawing).

The collector 110 and the cover 120 will be described with reference to the schematic cross-sectional view taken along the line 2 and B-B which is a schematic cross-sectional view taken along the line A-A of FIG.

The cover 120 forms a plurality of second through holes 121. The second through hole 121 is formed so that the diameter formed on the upper surface of the cover 120 is larger than the diameter formed on the lower surface. Accordingly, foreign matters generated in the drum 100 are not easily discharged into the first through hole (101 in FIG. 1), and are easily collected in the collecting tube 110 through the second through hole 121 formed in the cover 120. do.

As described above, one end of the cover 120 is hinged to the collecting container 110, the other end is coupled to the release.

A predetermined hinge portion 122 is formed at one end of the cover 120. Hinge portion 122 can be applied to any of the commonly known hingeable configuration.

A hinge coupling portion 111 rotatably coupled to the hinge portion 122 is formed at one end of the collecting container 110 that is hinged to one end of the cover 120. The hinge coupler 111 may be formed separately or integrally with the collecting container 110.

As described above, the drum washing machine having the drum having the foreign matter collecting device of the present invention has been described with reference to the preferred embodiment of the present invention, but modifications, changes, and various modifications are possible without departing from the spirit of the present invention. It is obvious to

According to the present invention, since foreign matters such as lint generated during washing are collected by the collecting device formed on the drum of the drum washing machine, the user can collect and remove the foreign matters at appropriate times.

In addition, since the foreign matter is collected by the collecting device and the foreign matter does not flow into the filter and the drain pump of the drum washing machine when the washing water is discharged, it is unnecessary to replace the filter due to the accumulation of foreign matter and there is no damage to the drain pump.
