Description

[Detailed Description of the Invention] The present invention relates to a dehydrating/washing machine in which a water channel is formed below the agitating blade at the inner bottom of the rotating tub, leading from the inside of the rotating tub to the drain valve. The present invention relates to a lint trapping device for a washing machine that also serves as a dehydrator for catching lint coming out of laundry during washing.

Conventionally, dehydrating/washing machines that have a waterway connected from the inside of the rotating tub to the drain valve formed below the agitating blades at the inner bottom of the rotating tub store water only inside the rotating tub to save water. After washing, the drain valve is opened, and the water can be drained from between the stirring blade and the bottom of the rotating tank around it, through the position below the stirring blade, and then around the shaft below it to the outside of the machine from the drain hose. It looks like this.

However, with this product, lint from the laundry during washing tends to collect below the stirring blade, and the collected lint can collect on the underside of the stirring blade, around the shaft, or on the ground near these. There is a problem in that thread waste gets entangled around the periphery of the hole, and the entangled thread waste encourages other thread waste to become entangled, and eventually accumulates to the extent that it blocks the water channel, resulting in a significant reduction in drainage capacity.

There is also the drawback that when the waterway is blocked as described above, the water level switch connected to the waterway becomes inoperable.
Furthermore, there was a drawback that the drainage valve was clogged due to the lumps of lint that were deposited and sometimes released and flowed out, causing the drainage valve to malfunction.

This invention was made in view of the above-mentioned circumstances,
Therefore, the purpose is to capture and easily remove lint without letting it reach the waterway below the stirring blade, thereby maintaining good drainage capacity and ensuring that the water level switch operates reliably. In addition, it is possible to reliably prevent clogging of the drain valve, and furthermore, it is possible to firmly hold the removable lint filter in place, which is a practical important point that does not cause problems such as laundry digging in. It is an object of the present invention to provide a useful lint trapping device for a washing machine that also serves as a dehydrator.

The ends of the connecting pipe 23 are connected, and the tip end of the connecting pipe 23 is connected to the suction side of the drain valve 24.

Reference numeral 25 denotes an air trap formed in the middle of the connecting pipe 23, which is connected via an air tube 26 to a water level switch 28 installed inside the operation box 27 on the outer box 1 shown in FIG.
29 is a connecting pipe that communicates the discharge side of the drain valve 24 with the T-shaped pipe 12.

On the other hand, 30 is a concave portion formed in the bottom of the rotary tank 2 by bulging downward, and this is placed on a support 32 fixed to the upper end of the dehydration shaft 14 with a nut 31. It is fixed with a plurality of bolts 34 (only negative ones are shown) together with the filter stopper 33 of the product.

As a result, the dewatering shaft 14 faces into the rotary tub 2 from the uppermost opening of the gap 18, following the inside of the recess 30, and the washing shaft 13
The upper end of the washing shaft 13 protrudes into the recess 30, and the stirring blade 3 is attached to the upper end of the protruding washing shaft 13 with a screw 36 through a washer 35.

There is a space 37 below the stirring blade 3 where the filter stopper 33 is located, and this space 37 communicates with the gap 18, so that the inside of the rotating tank 2 is The above-mentioned space 37 - gap 18 hole 19.20 - seal 16
．． 17, a water passage 38 is formed which passes through the connecting rod body 22 and the connecting pipe 23 in this order and continues to the drain valve 24.

Reference numeral 39 denotes a retaining portion formed on the filter stopper 33, which is a retaining portion of the filter stopper 33, as shown in FIG. In other words, the parts directly used for attachment and fixation to the solid fixing part 40 protrude only from each edge of the soil, and protrude outward to the extent that the outer periphery of the stirring blade 3 extends.

The filter stopper 33 has an annular shape that surrounds the center of the stirring blade 3 as a whole, and only the above-mentioned fixing parts 40 are formed in a concave shape, and the remaining parts are relatively hollow. It is formed into a raised shape, and a cavity 41 serving as a circulation path is formed below each of the raised cavities between it and the bottom of the rotary tank 2. In short, it also serves as a partition member.

Here, reference numeral 42 denotes a water passage part which is provided between the stirring blade 3 and the bottom of the rotating tank 2 around it by forming the recessed part 30 with a diameter large enough to consist of the stirring blade 3, and is connected to the water channel 38. Furthermore, a step portion 43 is formed on the peripheral wall of this water passage portion 42, and furthermore, stoppers 44 are provided protruding from the step portion 43 at several locations.

Reference numeral 45 is a lint filter made of, for example, a synthetic resin molded product, and this also has ribs 47, comb teeth 48, and comb teeth 49 in order from the outside on the lower surface of an annular substrate 46 that is inclined slightly downward toward the center. The comb teeth 48 are protruded from each other and are located close to the outer comb teeth 48 on the substrate 46.
A water passage hole 50 is provided between the comb teeth 48 and the rib 47.
A large number of water passage holes 51 are formed in alignment with each of the thin prismatic teeth 48a, and at the same time, water passage holes 51 are formed in a portion between the comb teeth 49 and the comb teeth 48, which are located close to the inner comb teeth 49. A large number of comb teeth 49 are formed in alignment with each narrow prismatic tooth 49a of the comb teeth 49, and the outer comb teeth 48
The inner comb teeth 49 are arranged by shifting the positions of the teeth 48 a and 49 a so that, for example, one of them faces between the teeth of the other.

Further, the lint filter 45 as described above includes the substrate 46.
A ridge 52 that functions as a jetty is provided on the upper surface of the innermost periphery of the comb teeth 49, and the comb teeth 49 have wide portions 53 at several locations corresponding to the fixing portions 40 of the filter stopper 33. A claw 54, which is a secured portion, is formed on each of these.

Therefore, the number of claws 54 is the same as the number of claws 39 on the filter stopper 33 on the inner edge of the lint filter 45.

Furthermore, in the intermediate portion of the substrate 46 of the lint filter 45, a hole 5 having the same shape as the hole 55 through which the screw 36 in the center of the agitating blade 3 passes through is provided at a position aligned with the claw 54.
6 respectively.

Here, the hole 55 at the center of the stirring blade 3 has notched holes 57 on both sides when the screw 36 and the washer 35 are removed.
are in communication with each other, and a fifth hole is provided in the notch holes 57 and 55, respectively.
Insert the inverted T-shaped tip 58a of the removal tool 58 shown in the figure and position the tip 58a to the space 59 between the notch hole 57 and the upper end of the washing shaft 13 below the hole 55, After that, if you turn the removal tool 58 by about 90 degrees and pull it up, the tip 58 a of the removal tool 58 will be removed.
The whole stirring blade 3 can be removed upwardly from the washing shaft 13 by hooking it on the peripheral edge of the hole 55 other than the notch hole 57.

Therefore, the hole 56 of the lint filter 45, which has the same shape as the hole 55 of the stirring blade 3, has notches 60 on both sides, and the above-mentioned removal tool 5 is attached to the notch holes 60 and 56.
The lint filter 45 can be removed by operating the lint filter 8 in the same manner as in the case of the agitating blade 3 described above.
This is the removable part of No. 5.

Further, the substrate 46 of the lint filter 45 is formed with recessed notches 61 corresponding to the stoppers 44 at several places on its periphery, and while the recessed notches 61 are fitted into the stoppers 44, the lint filter 45 is The entire body is inserted into the water passage portion 42 from above, and thereby each comb tooth 48, 49
In addition to locating the rib 47 in the water passage section 42, the rib 47 is placed in the stepped section 4.
3, and on the other hand, attach the claw 54 to the filter stopper 33.
With this, the lint filter 45 is positioned in the water passage section 42 and removably engaged with the filter stopper 33.

Next, to describe the operation, first, during washing, water supplied into the rotary tank 2 after the drain valve 24 is closed reaches the water passage part 42 from the water passage hole 50.51 of the lint filter 45. Between each tooth 48a of the comb teeth 48 existing in the iron part and between the comb teeth 4
The space 37 below the stirring blade 3 passes between each tooth 49 a of 9.
- The gap 18, the hole 19.20, the seal 16.17 are connected in series to fill the water passage 38 up to the drain valve 24, which is the rotor body 22 and the connecting pipe 23. After that, the water level is gradually raised in the rotating tank 2, and eventually from the air trap 25. Water level switch 28 is activated via air tube 26.

When the water level switch 28 operates in this way, the water supply described above is stopped and the motor 4 is instead energized to rotate the stirring blades 3, and the rotated stirring blades 3 do not remove the ice in the rotating tank 2. Stir with laundry.

In the vicinity of the stirring blade 3, the water stirred in this way is filtered through the lint filter 4 by the pumping action caused by the stirring blade 3.
The water flows from the water holes 50 and 51 of No. 5 to the water passage portion 42, and in this water passage portion 42, the water passes through the points 483 and 498 while hitting each tooth 48a of the comb teeth 48 and each tooth 49a of the comb teeth 49. The lint filter further passes through the cavity 41 under the filter stopper 33 and rises along the lower surface of the stirring blade 3 into the upper rotating tank 2 from the gap between the outer peripheral edge of the stirring blade 3 and the inner peripheral surface of the lint filter 45. The lint discharged from the laundry is repeatedly circulated, and the lint floating in the water from the laundry is collected towards the bottom of the agitating blade 3 and passes through a lint filter 45 on the way. Especially that comb tooth 4
8 and each tooth 49a of the comb teeth 49, and is captured.

In particular, in addition to providing the folding comb teeth 48 and the comb teeth 49 in two stages, the positions of the respective teeth 48 a and 49 a are shifted, so that, for example, thread waste leaking from the outer comb teeth 48 can also be absorbed into the inner comb teeth. The comb teeth 49 allow the thread waste to be captured without leaking, and thus a large amount of thread waste can be captured very efficiently.

Also, water holes 50 and 51 adjacent to the outer comb teeth 48 and the comb teeth 49 on both sides are connected to the outer comb teeth 48 and the comb teeth 49 on both sides.
Since it is provided in alignment with the comb teeth 48a and 49a, the lint that has passed through the water holes 50 and 49a together with the running water is captured by the teeth 48a and 49a of the comb teeth 48 and 49 without deviating from them. In particular, since the inner comb teeth 49 do not have any comb teeth beyond them, consideration must be given to capturing the thread waste without deviating it as described above, thereby making it possible to capture the thread waste even more efficiently. It is.

After this, the rotating tub 2 is rotated at high speed by the motor 4, and the water in the rotating tub 2 is shaken off and discharged from the top of the rotating tub 2 along with the water from the laundry by the centrifugal force. Sometimes, by opening the drain valve 24, some of the water can be discharged from the water channel 38 to the outside of the machine through the T-shaped pipe 12 and the drain hose 11. The lint contained in the lint passes through the lint filter 45 just before reaching the water channel 38.
It gets caught on the comb teeth 48 and 49 in the same manner as described above and is also efficiently captured.

The lint thus captured can be removed by removing the lint filter 45 after all operations have been completed, and cleaning the lint filter 4 with running water from a faucet, for example.
In particular, in this case, the lint filter 45 is a filter stopper 33 that is inserted into the water passage section 42 between the stirring blade 3 and the bottom of the rotating tank 2 around it and protrudes outward from the stirring blade 3. The claw 39 is the engaging part, and the claw 54 is the engaged part.
Therefore, it is not necessary to remove the stirring blades 3 one by one, and of course, it is not necessary to remove the screws or the like one by one. Since it can be easily removed by simply pulling it up using the removal tool 58, it is extremely convenient and convenient for removing captured thread waste.

Therefore, the water channel 38 and the lint filter 45 themselves can be cleaned without clogging and good drainage capacity can be maintained by frequent cleaning, and the water level switch 28 etc. can also be operated reliably. , and furthermore, the drain valve 24
It is possible to reliably prevent clogging, etc., and eliminate these failures more reliably.

In addition to the above, in this embodiment, the filter stopper 3
3, only the fixing part 40, which is the part directly used for attaching and fixing the bolt 34 to the bottom of the rotating tank 2, that is, to the lower position of the stirring blade 3, is provided with a claw 39, which is a retaining part, and the lint filter is attached to the fixing part 40. 45 is engaged and attached, the lint filter 4 is attached to the part other than the fixed part 40.
5, the fixing part 40 does not deform even if the lint filter 45 is repeatedly attached and detached, and therefore the lint filter 45 can be firmly held in the lower position at all times. The part other than the fixed part 40, that is, the sinus 41
However, due to the easy deformation of this part, the lint filter 45 can only be held in a state where the lint filter 45 is further lifted from its fixed position. Taking into consideration that the laundry may get stuck under it, this is effective in preventing the laundry from getting stuck.

The lint filter 45 has the same number of pawls 54 as engaged parts that are directly engaged with the pawls 39 of the filter stopper 33 as the pawls 39 that are the engaging parts, and a removal part is provided at a position aligned with the pawls 54. According to this embodiment, which has the hole 56 and the cutout hole 60, it is possible to prevent the lint filter 45 from deforming itself due to an operating force such as a pulling force at the time of removal. 45 can be installed.

In this case, according to the present embodiment, the holes 56 and notch holes 60 are provided in all the positions of the claws 54, so that the lint can be removed from the direction in which the work is most easily performed. Although the filter 45 is removable, this is not always necessary, and therefore the hole 56 and notch hole 60, ie, the removal portion of the lint filter 45, are provided with at least one of the claws 54, ie, the engaged portion. It is sufficient to provide the blades at the same locations, and although it is convenient that the removal tool 58 for the stirring blade 3 can also be used for removal, it is not necessary.

According to this embodiment, the lint filter 45 is attached by fitting the recessed part 61 into the stopper 44.
In addition to the so-called positioning guide effect in which the pawls 39 and 54 are accurately aligned and engaged, a rotation preventing effect is obtained to maintain their alignment against rotational movement of the lint filter 45. filter 45
Even if the lint filter 45 is rubbed and rotated by the laundry, this can be reliably prevented and the lint filter 45 can be prevented from coming off. It is also possible to prevent any kind of intrusion.

Here, FIG. 6 shows a different embodiment of the present invention.
This fixing part 4 of the filter stopper 33 replaces the stopper 44 provided on the stepped part 43 around the water passage part 42 described above.
A stopper 62 is provided at the
The wide part 53 of the lint filter 45 is held between the wide portions 53 of the lint filter 45, so the form is different from that of the stopper 44, but the function is similar to that of the stopper 44, and therefore the same positioning guide as described above is used. It is possible to obtain an anti-rotation effect in addition to the anti-rotation effect.

Of course, in this case, the lint filter 45 does not need the recessed part 61, but the consideration provided by the stopper 62, together with the consideration given to the stopper 44 and the provision of a removable part, are only necessary. It is fine as long as you have it.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings; for example, a net may be used instead of comb teeth in the lint filter to capture lint, without departing from the gist. It can be implemented with appropriate changes within the scope.

As explained above, the present invention provides a dewatering/washing machine in which a waterway connected from the rotary tank to the drain valve is formed at a position below the stirring blade at the inner bottom of the rotating tank. The outer edge of the fixed part that is attached and fixed to the fixing part and directly used for the attachment and fixing has an engaging part that protrudes outward from the stirring blade, and the part other than the fixed part is raised to form a circulation path below each part. A filter stopper that also serves as a partition member is provided, and a water passageway that overlaps the waterway between the stirring blade and the bottom of the rotating tank around the stirring blade is provided with a filter stopper that passes through the water passageway and passes through the circulation path. By inserting a lint filter that captures lint from circulating running water and engaging the retained part formed on the inner edge of the lint filter with the retained part, the lint filter can be removably attached and used for command. This is characterized by the fact that the thread waste from the laundry can be captured without reaching the waterway below the stirring blade, and the captured thread waste can be collected without removing the stirring blade one by one. It can be easily removed by easily removing the lint filter, which can maintain good drainage capacity, ensure that the water level switch operates reliably, and prevent clogging of the drain valve. Furthermore, the lint filter for this purpose can be firmly held in a fixed position at all times without causing problems such as laundry getting stuck in it, etc., and has many excellent practical effects.
