Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a filter device in a clothes dryer.

[0002]

2. Description of the Related Art The construction of a basic filter device in a conventional clothes dryer is shown in FIGS. In FIG. 4, 1 is a filter cover, 2 is a net filter, 3
Is a nonwoven fabric filter, 4 is a clothes dryer, 5 is a drum, 6
Is a moisture outlet, and the filter component is detachably attached to the moisture outlet 6 in the drum 5. Figure 5
Is a filter device in which a paper filter 7 is arranged between the filter cover 1 and the net filter 2.

[0003]

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

A. Since the filters 3 and 7 are located inside the drum 5, the filters 3 and 7 are difficult to remove 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 constitution of the present invention is as follows. 1. A filter device for a clothes dryer, wherein a long filter is arranged so as to cross the front of the moisture outlet, and the filter is automatically wound up by a fixed amount under a fixed condition. 2. A filter mounting shaft arranged on one side of the moisture outlet, a filter winding shaft arranged on the opposite side of the filter mounting shaft, a drive motor for driving the filter winding shaft, and controlling the drive motor Drying clothes comprising a controller and a filter made by rolling a long body in a roll shape, attachable to the filter mounting shaft, and capable of being continuously wound on the winding shaft from the end. Device in the machine.

The drive motor is driven according to the operating time of the clothes dryer, the number of drying operations, or when the temperature near the burner combustion cylinder rises above a certain level to wind up a certain amount of the filter. To configure.

[0010]

When the clothes dryer is used and more than a certain amount of lint adheres to the filter, the controller drives the drive motor to wind the filter to a position where the lint adhered part is avoided. By repeating this, the clothes dryer can be used without changing the filter until the filter is completely wound up.

In the present invention, the filter is a disposable type.

[0012]

1 and 2 show a filter device according to the present invention. Reference numeral 10 is a filter device, 11 is a free-rotating filter mounting shaft, and a filter roll 12a, in which a long paper filter 12 is wound in a roll shape, is detachably mounted on the mounting shaft 11. 13 is a winding shaft driven by a drive motor 14, 15 is a winding drum, 16 is a guide roll,
Reference numeral 18 is a moisture outlet, and 19 is a filter cover. Reference numeral 20 denotes a controller for controlling the drive motor 14 so that the drive motor 14 is driven when the operating time of the clothes dryer is accumulated for a certain period of time, and a certain amount of the filter 12 is wound onto the winding drum 15. Control. The filter mounting shaft 11, the winding shaft 13, and the winding drum 15 can be freely removed. In the case of the embodiment, the guide roll 16 is provided, but the guide roll 16 is not necessarily attached. FIG. 3 shows an embodiment of a clothes dryer in which the filter device 10 having the above structure is attached to the moisture outlet 17 in the drum.
21 is a clothes dryer, 22 is a drum, 23 is a fan, 24
Is a drum rotation belt, 25 is a motor, 26 is a gas burner, and 27 is a door.

In the case of the embodiment, when the filter 12 is used up or when the remaining amount of the filter 12 is low, a lamp or an alarm buzzer is used to notify the signal that the replacement is required.

[0014]

INDUSTRIAL APPLICABILITY As described above, according to the present invention, by automatically moving (winding) a long filter under a certain condition under a certain condition, lint does not have to be replaced each time. . As a result, the following effects are achieved. a. Eliminates the hassle of cleaning and replacing filters. b. Can always be used without clogging. c. If the filter runs out, a device to notify this will be installed so that the filter replacement time will not be lost.
