The outline of the filter cleaning device according to the present invention will be described with reference to these figures. The filter cleaning device 10 according to the present invention is movably provided in a first filter body 1 that collects dust, a ventilation passage 2 provided on the upstream side of the filter body 1, and the ventilation passage 2. At the same time, it has a cleaning body 3 that comes into contact with the first filter body 1 and removes dust adhering to the first filter body 1, and an opening 4, which accommodates dust that communicates with the ventilation passage 2 through the opening 4. It has a chamber 5, a dust guide wall 7 for guiding the dust removed by the cleaning body 3 to the dust storage chamber 5, and a second filter body 1a provided in a part of the dust storage chamber 5 to compress the dust. ing. The dust guide wall 7 extends from the inner wall 10a of the filter cleaning device toward the downstream side of the ventilation. Further, the cleaning body 3 uses a drive motor (not shown) provided on the main body side of the clothes dryer 20 as a drive source, and a gear 3b provided on the rotation shaft of the cleaning body 3 is a drive motor (not shown). By engaging with the output shaft (not shown), the power is transmitted to the cleaning body 3 and rotates.

Then, during the drying operation, as shown by the arrow in FIG. 3, ventilation flows from the arrow B side to the arrow C side. At this time, as shown in FIG. 4, the cleaning body 3 is in a state of standing by at a position substantially parallel to the ventilation. Here, the dust guide wall 7 is installed to ensure that the dust is stored in the dust storage chamber 5 and that the rectifying plate has a function of improving the passage of ventilation.

FIG. 5 is a cross-sectional view showing a first embodiment of the filter cleaning device according to the present invention, showing a state before and after cleaning. The filter cleaning device 10f of the first embodiment shown in FIG. 5 cleans the first filter body 1f at the end of the drying operation, and specifically, with the first filter body 1f that collects dust. , A ventilation passage 52 provided on the upstream side of the first filter body 1f, and a ventilation passage 52 movably provided in the ventilation passage 52, and abutting on the first filter body 1f to form a first filter body 1f.

The dust guide wall 24 extends from the inner wall of the filter cleaning device 10f toward the downstream side of the ventilation.

During the drying operation, the cleaning body 19 is in a state of standing by at a position substantially parallel to the ventilation. Further, the length of the cleaning body 19 may be longer than the radius of the arc of the filter body 1f, which allows the tip portion 19a to bend and scrape off the dust 6 as shown in FIG. Further, when the tip portion 19a of the once bent cleaning body 19 returns to its original position, the dust 6 can be bounced diagonally downward, so that the dust 6 can be more reliably stored in the dust storage chamber 12c. .. Further, by making the shape of the tip of the tip portion 19a of the cleaning body 19 having irregularities as shown in FIG. 5, the effect of scraping off the dust 6 can be expected.

FIG. 6 is a cross-sectional view showing the filter cleaning device 10f of the first embodiment, and shows a state during a compression operation after cleaning the filter body 1f. As shown in FIG. 6, the cleaning body 19 is configured to be movable to a position where the ventilation to the first filter body 1f is restricted and the wind speed of the ventilation to the second filter body 1g is increased. Specifically, the cleaning body 19 is stopped at a position where the tip portion 19a of the cleaning body 19 contacts the inner wall of the filter cleaning device 10f. As a result, the air passage to the first filter body 1f is blocked, and the wind speed of ventilation to the second filter body 1g increases, so that the dust on the second filter body 1g is compressed. Become. The compression operation can also be performed during the drying operation.

In the filter cleaning device 10f of the first embodiment configured as described above, the cleaning body 19 restricts the ventilation to the first filter body 1f, so that the mechanism is not complicated and the filter cleaning device 10f is used. It can be miniaturized. Further, by moving the cleaning body 19 to a position where the wind speed of ventilation to the second filter body 1g is increased, the dust remaining in the ventilation passage 52 can be reliably transferred to the dust storage chamber 12c. , The dust 6 in the dust storage chamber 12c can be reliably transferred to the second filter body 1g.

FIG. 7 is a cross-sectional view showing the filter cleaning device 10f of the first embodiment, showing a state after repeating a series of operations from the drying operation to the cleaning of the filter body 1f and the compression operation. As shown in FIG. 7, the dust 6 is stored up to the vicinity of the opening 11d of the dust storage chamber 12c. At this time, the dust 6 is crushed and compressed between the tip portion 24a of the dust guide wall 24 and the tip portion 19a of the cleaning body 19 and pushed into the dust storage chamber 12c. Further, since the inner wall is formed to form an arc from the root of the dust guide wall 24 to the inner bottom surface of the dust storage chamber 12c, the dust 6 pushed by the cleaning body 19 is formed along the arced inner wall. Is sequentially pushed toward the 1 g side of the filter body. In this way, since the dust 6 can be transferred to the back of the dust storage chamber 12c while being compressed by the cleaning body 19, more dust 6 can be stored in the dust storage chamber 12c.

FIG. 8 is a cross-sectional view showing 10 g of the filter cleaning device of the second embodiment, and shows a state at the time of compression operation after cleaning the first filter body 1f. Further, FIG. 9 is a cross-sectional view showing 10 g of the filter cleaning device of the second embodiment, showing a state after the completion of the compression operation. The filter cleaning device 10g of the second embodiment will be described below with reference to these figures.

The difference between the filter cleaning device 10g of the second embodiment and the filter cleaning device 10f of the first embodiment is that the dust 6 whose dust trapping surface is captured falls on a part of the second filter body 1g due to gravity. It is a point that it is installed at an angle. Since other configurations are the same as those of the filter cleaning device 10f of the first embodiment, the description thereof will be omitted.

As described above, a part of the second filter body 1g is installed at an angle so that the dust 6 whose dust trapping surface is captured falls due to gravity, and when the ventilation is stopped, it is installed at an inclination. As shown in FIG. 9, the dust 6 adhering to a part of the dust trapping surface of the second filter body 1g is dropped, so that the dust 6 of the second filter body 1g installed at an angle is inclined. Since clogging can be prevented, the efficiency of the drying operation is improved, and more dust 6 can be compressed and stored.

FIG. 10 is a cross-sectional view showing the filter cleaning device 10h of the third embodiment, showing the state before and after cleaning. Further, FIG. 11 is a cross-sectional view showing the filter cleaning device 10h of the third embodiment, showing a state during the compression operation. The filter cleaning device 10h of the third embodiment will be described below with reference to these figures.

The filter cleaning device 10h of the third embodiment is movable in the first filter body 1f that collects dust, the ventilation passage 52 provided on the upstream side of the first filter body 1f, and the ventilation passage 52. It has a cleaning body 19 that is freely provided and that comes into contact with the first filter body 1f and rotates and removes dust 6 adhering to the first filter body 1f, and an opening 11d, through the opening 11d. A dust accommodating chamber 12c communicating with the ventilation passage 52, a dust guiding wall 24 for guiding the dust 6 removed by the cleaning body 19 to the dust accommodating chamber 12c, and a part of the dust accommodating chamber 12c are provided to compress the dust 6. It has a second filter body 1g, and a wind speed adjusting means 13 that limits the ventilation to the first filter body 1f and increases the ventilation speed of the ventilation to the second filter body 1g.

The wind speed adjusting means 13 is made of a soft material, and is stored in a movable state in a storage portion 14 above the cleaning body 19 at the time of cleaning. Then, during the compression operation, as shown in FIG. 11, the cleaning body 19 stops in the standby position. After that, the wind speed adjusting means 13 protrudes from the storage portion 14 and stops in a state of blocking the air passage to the first filter body 1f. As a result, the wind speed of ventilation to the second filter body 1g is increased, so that the dust remaining in the ventilation passage 52 can be reliably transferred to the dust storage chamber 12c, and the dust in the dust storage chamber 12c can be reliably transferred. 6 can be reliably transferred to 1 g of the second filter body and compressed. Further, when compared with the filter cleaning devices of the first embodiment and the second embodiment, it is possible to prevent the cleaning body 19 from being exposed to warm air and deteriorating during the compression operation, and to extend the life of the cleaning body 19.

FIG. 12 is a cross-sectional view showing the filter cleaning device 10i of the fourth embodiment, showing a state in which the wind speed adjusting means 13a is housed in the storage unit 14a. Further, FIG. 13 is a cross-sectional view showing the filter cleaning device 10i of the fourth embodiment, showing a state in which the wind speed adjusting means 13a protrudes from the storage portion 14a. The filter cleaning device 10i of the fourth embodiment will be described below with reference to these figures.

The filter cleaning device 10i of the fourth embodiment has a first filter body 15a for collecting dust, a ventilation passage 52 provided on the upstream side of the first filter body 15a, and an opening 11d. The dust accommodating chamber 12c communicating with the ventilation passage 52 through the opening 11d, the dust guiding wall 24 for guiding the dust 6 dropped from the first filter body 15a to the dust accommodating chamber 12c, and a part of the dust accommodating chamber 12c. Wind speed adjustment provided to limit ventilation to the second filter body 15b that compresses the dust 6 and the first filter body 15a, and to move to a position that increases the wind speed of ventilation to the second filter body 15b. It has means 13a.

The dust trapping surface of the first filter body 15a is tilted so that the trapped dust falls due to gravity. Then, even if the dust 6 is scattered during the fall, the dust guide wall 24 can surely drop the dust 6 into the dust storage chamber 12c. Further, the dust trapping surface of the second filter body 15b is also installed so as to be inclined so that the trapped dust falls due to gravity.

In the filter cleaning device 10i of the fourth embodiment configured as described above, as shown in FIG. 12, when the wind speed adjusting means 13a is housed in the storage unit 14a, the first filter body 15a and the second filter body 10a Since ventilation is performed by both of the filter bodies 15b of the above, the effect of compressing the dust 6 is small, and the dust 6 falls and accumulates on the bottom surface of the dust storage chamber 12c in a bulky state.

On the other hand, as shown in FIG. 13, when the wind speed adjusting means 13a protrudes from the storage portion 14a, the wind speed adjusting means 13a blocks the air passage to the first filter body 15a. The dust 6a is dropped and accumulated on the bottom surface of the dust storage chamber 12c in a compressed state by the filter body 15b of the above. The dust 6 adhering to the first filter body 15a can be dropped to the bottom surface of the dust storage chamber 12c by gravity because the dust trapping surface of the first filter body 15a is inclined. When the wind speed adjusting means 13a protrudes from the storage portion 14a, the wind speed adjusting means 13a can also scrape off the dust 6 adhering to the first filter body 15a, which is also included in the present invention.

In the third and fourth embodiments, the wind speed adjusting means 13 and 13a are provided on the upstream side of the first filter bodies 1f and 15a, but the ventilation to the first filter bodies 1f and 15a is restricted. If possible, wind speed adjusting means 13 and 13a can be provided on the downstream side of the first filter bodies 1f and 15a, which are also included in the present invention.

The filter cleaning device according to the present invention is used to remove dust adhering to the filter. Further, the clothes dryer according to the present invention is used as a clothes dryer provided with a filter cleaning device.
