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.

[0002]

2. Description of the Related Art A basic filter device in a conventional clothes dryer is shown in FIGS. FIG. 4 shows a filter device in which the filter cover 1, the net filter 2 and the non-woven fabric filter 3 are detachably attached to the moisture exhaust port 6 provided in the drum 5 of the clothes dryer 4, and FIG. 5 shows the filter cover 1 and the net. Paper filter 7 between filters 2
Is a filter device having a configuration of arranging.

[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.

The arm with a brush is faced to the front side of the filter, and this arm is usually separated from the filter surface, and the brush is brought into contact with the filter surface during cleaning and the arm side is fixed to the main body and the drum is fixed. A clothes dryer with a filter cleaner that is configured so that the lint can be swept away while rotating, and the swept lint can be received by a detachable lint receiver.

The arm may be configured to be manually operated. Alternatively, the arm may be a motor or solenoid drive system, and the cleaner may be automatically controlled by driving this motor or solenoid for a certain period of time by detecting the operating time or number of operations of the clothes dryer or the temperature near the burner combustion cylinder. You may When lint is accumulated in the lint receiving room, 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 adhesion is calculated in advance by the operating time or the number of operations,
When the controller measures a certain operation time or number of times, the motor or solenoid is driven to bring the brush of the arm into contact with the filter surface and rotate the drum on the dryer side.
As a result, since the brush is fixed and the filter side rotates, the lint adhering to the filter surface is wiped off.
Lint that has been swept away collects lint. When the lint accumulates, an alarm lamp or buzzer sounds, so take out the lint holder and discard the lint.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, 10 is a filter, 11 is a drum, 12 is located on the front side of the filter 10, and an arm formed by brushing a brush 13 on the filter 10 side,
The arm 12 is fixed to the body side by an arm shaft 14 and is prevented from rotating. However, the solenoid 15 can freely move in and out in the axial direction. Reference numeral 16 is a detachable lint receiver, 17 is a filter cover, and 18 is a controller for the following control.

The operating time or the operating frequency of the clothes dryer or the temperature in the vicinity of the burner combustion cylinder is detected. When the time, the operating frequency and the temperature satisfy certain conditions, the solenoid 15 is driven to move the arm 12 to the filter 10 side. Move and brush 13
Is brought into contact with the surface of the filter 10 and the drum 11 is rotated for a predetermined time. By this rotation, the lint adhering to the surface of the filter 10 is wiped off by the brush 13. The swept lint collects in the lint receiving chamber 16. When the lint collects, an alarm is emitted by a lamp or a voice, and the lint receptacle 16 is taken out and the lint is discarded.

FIG. 3 shows an example in which a cleaner is attached to the clothes dryer. 19 is a moisture exhaust fan, 20 is a drum rotation motor, 21 is a gas burner, and 22 is a door. In the case of the embodiment, the operating time is adopted as a means for detecting that lint has accumulated in the lint receiving chamber 16.

[0015]

As described above, the present invention has the following effects because the cleaner with the brush, which is controlled under a certain condition, is attached to the front side of the filter. 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.
