DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clothes dryer with a filter cleaner configured to eliminate the trouble of cleaning or replacing a filter by automatically cleaning the filter.

[0002]

2. Description of the Related Art FIGS. 4 and 5 show a basic structure of a filter in a conventionally known clothes dryer. 4 filter cover 1, the net filter 2, in the filter device of detachably mounting configuration in which the nonwoven fabric filter 3 to a discharge Shimekuchi 6 provided on the clothes dryer 4 in the drum 5, 5 and the filter cover 1 This is a filter device having a configuration in which a paper filter 7 is arranged between the net filters 2.

[0003]

However, the above-mentioned known filter devices have the following disadvantages.

A. Since the filters 2, 3, and 7 are attached to the back of the drum 5, the filters 2, 3, 7
It is difficult to attach and detach when cleaning or exchanging. In particular, when the clothes dryer is installed on the washing machine, it is difficult to remove the clothes dryer because the height is added.

B. In the case of the non-woven fabric filter 3, the collection efficiency is good, but it is difficult to remove the lint even when cleaning with a vacuum cleaner. For this reason, clogging of the filter 3 becomes faster as the number of uses increases.

C. In the case of the paper filter 7, it is possible to dispose it while ensuring the same collection efficiency as the nonwoven fabric filter 3, but the filter needs to be replaced once every 5 to 10 times.

An object of the present invention is to solve the above problems a to c.

[0008]

The construction of a clothes dryer with a filter cleaner according to the present invention is as follows.

A mode arranged at the lower center of the filter 10
Contact the front of the filter 10 about the rotation axis of the
Arm 14 with a brush 15 reciprocating left and right
And move the arm 14 to the left and right
A clothes dryer with a filter cleaner having a V-shaped lint support 18 as viewed from the front .

The cleaner detects the total operation time or the number of times of operation of the clothes dryer or the temperature in the vicinity of the burner combustion cylinder and drives the clothes dryer for a certain period of time. If lint accumulates in the lint reception, it is convenient to attach a means for notifying this by a lamp or sound.

[0011]

[Action] When the clothes dryer is used for a certain period of time, lint adheres to the surface of the filter. This lint is swept off by a cleaner driven by a motor, and the lint is collected. When the lint accumulates, the warning lamp lights or the buzzer sounds. In this case, remove the lint support and discard it.

[0012]

In FIG. 1, 10 is a filter, 11 is a dehumidification fan, 12 is a drum, 13 is a cleaner attached to the front side of the filter 10, and this cleaner 13 has an arm 14 to which a brush 15 is attached and And a motor 16 that rotates around an arm shaft 14a of the arm 14. 1
Reference numeral 7 denotes a filter cover, reference numeral 18 denotes lint, reference numeral 19 denotes a controller. The controller 19 drives the motor 16 to rotate the arm 14 when the total operation time of the clothes dryer reaches a predetermined time. The lint adhering to the filter 10 is swept down into the lint bearing 18 with the brush 15. The lint bearing 18 is detachably incorporated, and when the lint is accumulated, the lint bearing 18 can be removed and discarded.

In the embodiment, a cover 14b is formed on the arm 14 to prevent lint from scattering.
Further, the embodiment is provided with a lint alarm means for alarming by a lamp or voice when lint is accumulated in the lint bearing 18. Lint pool is cleaner 13
Can be detected by detecting the driving time, the number of times of driving, or the number of rotations of the arm 14.

FIG. 3 shows a brush 15 in the cleaner 13.
Is the rotation axis 1 of the arm 14 in contact with the front of the filter 10.
4a was placed in front center bottom of the filter 10, in the configuration described embodiments to perform the cleaning by reciprocally rotating the arm 14 at an angle left and right, lint receives 18 V
It is shaped like a letter.

[0015]

As described above, according to the present invention, a cleaner driven under a certain condition is attached to a filter.
The following effects are obtained. a. There is no need to clean and replace the filter. b. Can always be used without clogging. c. If the lint accumulates in the lint, it is convenient to attach a device to notify the lint so that the lint can be removed as soon as it accumulates.
