And in this thing, the apparatus which capture | acquires the lint contained in the dry wind which scattered from the laundry at the time of drying is appropriately provided.

(Problems to be Solved by the Invention) However, in the case of the above-mentioned one, there is almost no one provided with a device for separating lint contained in the washing water by being separated from the laundry at the time of washing, and therefore, the finish of the laundry is sufficiently clean It had a problem that it could not be obtained. Further, in this case, it is possible to adopt a filter that is used in a usual drum type dryer, but even in that case, it does not have the function of capturing the lint that appears during washing, and on the contrary, particularly This product has a problem that when the next washing is performed with the lint captured at the time of drying being left as it is, the lint thus captured flows out into the wash water and adheres to new laundry.

The present invention has been made in view of the above circumstances, and therefore an object thereof is to capture lint not only when it is dried but also when it is washed, and moreover, the captured lint is not discharged and a sufficiently clean finish of laundry is obtained. To provide an excellent washer / dryer that can obtain

[Structure of the Invention] (Means for Solving the Problems) The washing / drying machine of the present invention is provided with a mouth part for discharging washing air when the washing water comes in contact with the washing water during washing in a washing / drying room.
It is characterized in that it is provided with a filter which covers the mouth and forms a bag-like peripheral part, through which the washing water and dry air are passed and lint is captured from them and stored in the peripheral bag-shaped part. .

(Operation) According to the above means, the washing water passes through the filter at the time of washing and the dry air passes at the time of drying. Therefore, the lint contained in the washing water and the dry air can be captured by the filter, and further captured. Of the lint, the lint captured by the part covering the mouth is transferred to the surrounding bag-like part by the flow of washing water thereafter, and the lint captured by the bag-like part is retained in the bag-like part as it is, respectively. It can be stored in the bag-shaped portion.

Next, in FIG. 1, reference numeral 19 denotes a filter, which is attached to an annular frame 20 on the outer periphery and a circular receiving plate 21 on the inner periphery, as shown in detail in FIG. And a first filter 22 made of, for example, a nylon net, and an outer peripheral portion thereof is attached to an annular frame 23, and the inner peripheral portion is supported on the back side of the central portion by a protrusion 24.
It also has a second filter 26, which is also made of nylon net and is attached and loosened to a circular guard 25 having a cover 27. In addition, the cover 27 has a port 28 for both water passage and ventilation in the central portion, and a required number of ribs 30 for reinforcement of the water passage hole 29 are formed in the peripheral portion, and also for engaging attachment. A plurality of, for example, four claws 31 are formed at equal intervals. Similarly, the frame 23 of the second filter 26 is also formed with the same number of engaging attachment claws 32 on the peripheral portion, and correspondingly, holes 33 are formed in the frame 20 of the first filter 22. After all, the same number is formed. Thus, the first filter 22 fits the frame 20 into the opening 8 portion of the drum 2, more specifically, into the recessed step portion 34 formed around the opening 8 and screws.
The second filter 26 is fixed by the hole 35 of the first filter (frame 20) and the claw 32 of the second filter 26 and the cover 27.
The claws 31 of the drum 2 are sequentially engaged, so that the opening 8 of the drum 2 is
Part of the filter 19 is the first filter 22, the second filter 2

Now, in the case of the one configured as described above, at the time of washing,
With the laundry (not shown) and the required amount (washing water level h ₁ and rinsing water level h _{2 in} FIG. ₁ ) of washing water and detergent contained in the drum 2, a motor (not shown) drives the belt pulley 17 and the shaft. The rotation driving force transmitted to the drum 2 via 3 rotates the drum 2. During such washing, especially rinsing, the washing water should be put in the mouth of the cover 27 at the filter 19 part.
Circulation is carried out from 28 through the guard 25 and further through the first filter 22 and the second filter 26, and in particular the bag-like portion 36 thereof, from the hole 29 of the cover 27 back into the drum 2. In the middle of the process, the lint contained in the wash water is captured in the process of passing through the first and second filters 22 and 26, and all of them are moved into the bag-shaped portion 36 by the above-mentioned flow of the wash water. Are stored.

On the other hand, at the time of drying, the rotary power of the motor (not shown) is transmitted to the drum 2 through the same route as described above, and thus the drum 2 is rotated, and at the same time, the hot air generator (not shown) is operated. Then, the air in the drum 2 is sucked out through the air duct 11 and is subjected to heat exchange, heating, etc. to be changed into hot air which is a dry air, and then through the air supply duct 12 into the tub 1 and further. It is supplied into the drum 2 and passed through the drum 2. Then, the hot air enters through the mouth 29 of the cover 27 at the filter 19 portion, passes through the guard 24, and further passes through the first filter 22 and exits into the air circulation duct 11. In the middle of the process, however, the lint contained in the hot air is captured while passing through the first filter 22.

Further, the lint captured by the first filter 22 from the above-mentioned hot air is separated from the first filter 22 by the above-mentioned flow of washing water at the time of the next washing and is transferred to the bag-shaped portion 36. Stored in part 36.

As described above, according to the present embodiment, lint can be captured not only during drying but also during washing, and the captured lint can be stored in the bag-like portion 36, and the lint can be prevented from flowing out.
Therefore, it is possible to obtain a sufficiently clean finish with little or less lint attached to the laundry.

In addition to the above, in particular, in the above embodiment, the filter 19 is composed of the first filter 22 and the second filter 26, so the second filter 26 is removed at the time of cleaning. By doing so, it is possible to separately handle them, and therefore, it is possible to obtain a further effect that more reliable cleaning can be performed and the work can be easily performed.

However, the present invention is not limited to the embodiments described above and shown in the drawings. Therefore, the filter may be composed of one sheet, or conversely may be composed of three or more sheets. In addition, the washing / drying chamber may not necessarily be a drum, but may be appropriately modified and implemented without departing from the scope of the invention.

[Effects of the Invention] As is clear from the above description, the washer / dryer of the present invention is provided with a mouth at which the washing water comes into contact with the washing water during the washing in the washing / drying room and discharges the drying air at the time of drying. It is characterized in that it is provided with a filter that covers the bag and has a bag-shaped peripheral part that allows the washing water and the dry air to pass therethrough to capture lint and store the lint in the bag-shaped part around the bag. The lint can be captured not only when it is dried but also when it is washed, and the lint thus captured does not flow out, so that a sufficiently clean finish of the laundry can be obtained.
