Abstract

PURPOSE:To eliminate the troublesome cleaning and exchange of a filter by installing the cleaner which rotates by the motor driving on the front of the filter and installing a lint receiver at the lower part of the filter. CONSTITUTION:A cleaner 13 installed on the front of a filter 10 consists of an arm 14 with a brush 15 and a motor 16 rotating an arm axis 14a. When the total operation time of the cloth drying machine reaches a fixed time, a controller 19 drives the motor 16 and rotates the arm 14. The lint stuck on the filter 10 is brushed off in a lint receiver 18 with the brush 15. The lint receiver 18 is detachably incorporated and it can be removed when the lint is accumulated. A lint alarm means using an alarm by lamp or voice when the lint is accumulated in the lint receiver 18 is installed, and the accumulation of the lint can be detected by the driving time, driving frequency of the cleaner 13 or the detection of the number of revolutions of the arm 14.

Description

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, which is designed to eliminate the trouble of cleaning or replacing the filter by automatically cleaning the filter.

[0002]

2. Description of the Related Art The basic structure of a filter in a conventionally known clothes dryer is shown in FIGS. FIG. 3 shows a filter device in which a filter cover 1, a net filter 2 and a non-woven fabric filter 3 are detachably attached to a moisture exhaust port 6 provided in a drum 5 of a clothes dryer 4, and FIG. The filter device has a configuration in which a paper filter 7 is arranged between the net filters 2.

[0003]

However, the known filter device described above has the following drawbacks.

A. Since the filters 2, 3 and 7 are attached to the inner side of the drum 5, the filters 2, 3 and 7 are
It is difficult to put on and take off when cleaning or replacing. In particular, when the clothes dryer is installed on the washing machine, it is difficult to remove the clothes dryer because of the added height.

B. In the case of the non-woven fabric filter 3, the collection efficiency is good, but it is difficult to remove lint even after cleaning with a vacuum cleaner. Therefore, the clogging of the filter 3 becomes faster as the number of times of use increases.

C. In the case of the paper filter 7, it is possible to dispose of it while ensuring the same collection efficiency as that of the non-woven fabric filter 3, but it is necessary to replace the filter once every 5 to 10 times.

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

[0008]

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

On the front side of the filter, a cleaner which is driven by a motor to rotate under a certain condition or reciprocally rotates at a certain angle is attached, and a lint holder is detachably attached around or below the filter within a certain angle range. Clothes dryer with filter cleaner.

The cleaner detects the total operation time or the number of operations of the clothes dryer or the temperature in the vicinity of the burner combustion cylinder, and drives the cleaner for a predetermined time. If lint accumulates in the lint container, it is convenient to provide a lamp or a means for notifying the user by voice.

[0011]

When the clothes dryer is used for a certain period of time, lint adheres to the surface of the filter. This lint is swept away by a cleaner driven by a motor and collects lint. If the lint accumulates, the alarm lamp will light up or the buzzer will sound. In this case, remove the lint holder and discard it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, 10 is a filter, 11 is a dehumidifying fan, 12 is a drum, 13 is a cleaner attached to the front side of the filter 10, and this cleaner 13 is an arm 14 to which a brush 15 is attached, The motor 16 is configured to rotate around the arm shaft 14a of the arm 14. 1
7 is a filter cover, 18 is lint-accepting, 19 is a controller, and this controller 19 drives the motor 16 to rotate the arm 14 when the total running time of the clothes dryer reaches a certain time. The brush 15 wipes the lint adhering to the filter 10 into the lint receiving chamber 18. The lint receptacle 18 is removably incorporated, and when the lint has accumulated, the lint receptacle 18 can be removed and discarded.

In the case of the embodiment, the arm 14 is provided with a cover portion 14b for preventing the lint from scattering.
Further, in the embodiment, when the lint accommodating portion 18 is filled with lint, a lint warning means for warning the lint by a lamp or a voice is attached. Cleaner 13 for the lint pool
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 cleaner 13 with an arm 14
In another embodiment in which the rotary shaft 14a of the above is arranged below the filter 10 and the arm 14 is reciprocally rotated by a predetermined angle to perform cleaning, the lint receiving unit 18 has a V
It is configured in a letter shape.

[0015]

As described above, according to the present invention, since the cleaner which is driven under a certain condition is attached to the filter,
It has the following effects. a. There is no need to bother with filter cleaning and replacement. b. Can always be used without clogging. c. If the lint collects to accept lint, it is convenient to install a device to notify the lint so that the lint can be immediately removed when it collects.
