Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drum type washing machine, and more particularly to a lint collection structure that reliably collects lint generated in the drum during washing.

Conventionally, lint collection devices for drum-type washing machines have not been installed inside the drum, and the lint generated during washing can adhere to the holes in the peripheral wall of the drum or remain in the gap between the baffle and the drum. Therefore, it was not possible to remove all the lint from the aircraft.

In addition, lint also adhered to the laundry itself, making the laundry look bad.

The present invention attempts to reliably collect most of the lint by installing a lint collecting device inside the drum.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is rotatably held in a receiver tank 4 by a ball bearing 3 housed in a bearing receiver 2 so as to have a center axis of rotation in the horizontal direction, and has many through holes (not shown) in the peripheral side wall. It is a drum with

Reference numeral 5 designates a drum shaft to which one end side of the drum 1 is fastened, a drum pulley 6 is attached to the other end, and a motor 8
The rotation is transferred to the drum 1 via the V-belt 7 and the motor pulley 9.
is being communicated to.

10 is a door for loading and unloading the laundry, and 11 is a seal packing, which serves as a seal between the receiving tank 4 and the outer casing 12, and the door 10.
and the receiving tank 4 are sealed at the same time.

Reference numeral 13 denotes a water supply pipe for putting washing water into the receiving tank 4, and reference numeral 14 indicates a drain pipe for discharging the washing water in the receiving tank 4 to the outside of the machine.

Reference numeral 15 designates a plurality of panfuls attached within the drum, the specific shape of which is as shown in FIGS. 2 and 3.

This baffle 15 is long in the length direction of the rotation center axis of the drum 1, has a substantially mountain-shaped cross section in a direction perpendicular to this direction, and is hollow.

Furthermore, the baffle 15 includes a baffle body 15a and a side surface 1 that opens and closes using the top of the baffle body 15a as a fulcrum.
5b, and a large number of through holes 15c are formed in one side portion 15b.

The fulcrum structure for opening and closing is comprised of a protrusion 15a provided on the upper end surface of the one side surface 15b and a recess 15e formed at the top of the baffle body 15a to rotatably support the protrusion 15d. Become.

A filter stopper 16 and a claw 17 in the shape of a cutout circuit are integrally provided on the back surface of the negative side portion 15b.

Further, the hole 18 that engages with the claw 17 is formed in the baffle body 15.

On the other hand, a filter 1 is detachably attached to the back surface of the one side portion 15b.
9 is installed.

This filter 19 is constructed by pushing the periphery of a filter body 19a made of a net or the like into a groove 20a of a filter frame 20 using a filter presser 21.

The filter frame 20 engages with the filter stop 16, and
It is attached to the back surface of one side portion 15b of the baffle 15.

Further, the other side surface portion 1 corresponding to the one side surface portion 15b that can be opened and closed
A drainage hole 22 is provided at the bottom of 5f.

The above-described through hole 15c, filter main body 19a, and drain hole 22 constitute a washing water circulation section.

Further, the plurality of baffles 15 described above are arranged at equal intervals on the inner surface of the drum 1, but these baffles 15
Particularly, one side surface portion 15b that can be opened and closed faces each other.

In the above configuration, the baffle 15 rotates together with the drum 1 during washing.

At this time, the washing water enters into the baffle 15 through the through hole 15c of the one side portion 15b, passes through the filter body 19a, and flows out of the baffle 15 through the drain hole 22.

At this time, lint in the washing water is collected within the filter body 19.

Further, since a specific one of the plurality of baffles 15 is installed in the drum 1 so that one side surface portion 15b which can be opened and closed faces each other, even if the drum 1 rotates in either the left or right direction, the lint will not flow. Can be collected.

On the other hand, the collected lint can be easily discarded because the filter body 19a can be removed by opening the openable and closable side surface 15b, pulling out the filter frame 20 upward, and pulling out the filter holder 21. can.

Conversely, the filter body 19a is inserted into the groove 20 of the filter frame 20.
The filter body 19a can be attached to the filter frame 20 by pushing the filter holder 21 into the filter holder 21 at the same time as the filter holder 21. Furthermore, by pushing the filter frame 20 into the filter stopper 16, the filter body 19a can be attached to the back side of the one side part 15b. Attachment and detachment of 19a is extremely easy.

As is clear from the above embodiments, the present invention is extremely effective in collecting most of the lint in the drum, and the work of removing the collected lint is relatively easy. , the filter is housed in a baffle, so the filter does not come into direct contact with the laundry, which has extremely great practical value, such as keeping the filter's lifespan long.
