Abstract

PURPOSE:To improve maintenance properties of a filter by a method wherein a securing piece with a pawl to be engaged with a tumbler is rotatably inserted axially into near the periphery of the 2nd filter located at the back of the tumbler. CONSTITUTION:Lint shed by clothes during drying operation is carried to a lint filter unit 14 by circulating air and most of them are collected by the 1st filter 23. Fine dirt passed through the filter 23 is collected by the 2nd filter 16, causing lint and so on to be completely removed from the circulating air. The 1st filter 23 can be removed by pulling it up by hand from a filter guard 22. The 2nd filter 16 can be removed from the back of a tumbler 2 by turning a tongue part 20 of securing piece 18 provided in the plural axially in a 180-degree arc to change the position of a securing pawl 15, and to disconnect with the tumbler. Thus, the filters 23, 16 can be removed from a dryer body easily and the maintenance of them are easy.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a clothes dryer, and particularly to an improvement in a lint filter device suitable for collecting lint.

[Conventional technology]

The conventional phosphorus F filter device is disclosed in Japanese Patent Application Laid-open No. 59-214.
Phosphorus filter as described in 494''f:
The filter is triple-layered, one of which is fixed to the drying tram with screws, and the other two filters are attached to the filter fixed to the drum. The advantage of using a clothes dryer is that dirt and lint from clothes can be removed by the lint filter in the ventilation path, but if the lint filter is not maintained frequently, the filter itself may open.
Since I'Ii b'i decreases and drying time becomes longer, the maintenance described in 1iij is an indispensable work, and a product with good maintenance workability is desired. In the case of conventional phosphorus filters, two of the three-layer filters can be easily removed by the user, making maintenance easy, but those fixed with drum screws are easy to maintain. Since they are not removed, maintenance is often not performed, and as a result, the opening area is reduced, reducing the amount of ventilation and lengthening the drying time, often resulting in complaints.

[Problem to be Solved by the Invention 1] The above-mentioned conventional technology did not take into account the workability of filter maintenance, and there was a problem in which the user used the dryer without performing filter maintenance. .

An object of the present invention is to improve the maintainability of the filter.

[Means for Solving the Problems 1] In order to achieve the above object, in the present invention, the filter is fixed to the drying drum with screws, and the user can attach the filter to the drying drum as needed without using any tools. It is designed to be attached via a fixing piece that can be attached and removed.

[Function] The fixing piece is attached to one place near the outer periphery of the filter so that it can rotate freely around its axis, and one end of the fixing piece has a tock for engaging with a hole provided in the drying drum. have. A fixing piece is installed by the user to maintain the filter attached to the drying drum.
When rotated around the axis 80 degrees, the hole provided in the drying drum and!・The filter can be removed from the drying drum by disengaging from the hook.

[Example] Hereinafter, an example of the present invention will be described with reference to FIG. 1 is the outer frame, 2 is the rotating drum, 3 is the heat source, 4 is the exhaust [-],
5 is a double-winged fan, 6 is a fan casing, 7 is a motor that provides power, 8 is a bell that transmits the power of the motor 7 to the mouth mud drum 2, 9 is a round belt that transmits the power of Chiyo 7 to the double-winged fan 5, 10 is the first airtight fer 1-. II is the second
12 is a partition plate, 13 is a circulation duct that guides the circulating air discharged from the fan casing 6 to the heat source 3, and 14 is a lint filter device.

That is, what is shown in FIG. 1 includes a rotating drum 2 rotatably supported within an outer frame 1, a heat source 3 related to a heater for obtaining hot air, a belt 8 for driving the rotating drum 2,
It has a round belt 9 and a motor 7 for driving the double-blade fan 5. The rotation of the motor 7 rotates the double-blade fan 5 and the rotating drum 2, and the circulating air (solid arrow) generated by the rotation drives the heat source 3. When the laundry passes through, it is heated and enters the rotating drum 2, where the water content of the laundry is evaporated and dried. At that time, the lint and dirt generated from the laundry pass through the lint filter device 4 together with the circulating air, and the lint and dirt are collected.

Thereafter, circulating air is sent through the circulation duct 13 to the heat source 3 by the double-blade fan 5 to heat the clothes again and dry the clothes repeatedly.

Next, the present invention will be explained in detail with reference to FIG.

Lint filter device 1 located at the rear of the rotating drum 2
4, a second filter 16 having a fixing claw 15 near its outer periphery is engaged with the rotating drum 2 by a mounting claw 19 of a fixed piece 18 inserted into a plurality of fixed piece mounting bosses 17. It is firmly attached. The left end of the fixed piece 18 has a knob 20,
A user can grasp the knob 20 to rotate the fixed piece 18 about its axis. A filter guard 22 is attached to the front side of the lint filter device 14, and the filter guard 22 has an engaging claw 21 on the outer periphery that engages with the fixing claw 15 provided on the second filter 16. Filter 23 has been removed.

Hereinafter, the operations of the phosphor 1 to the filter device 14 will be explained in the second state 1.

The lint generated from the clothes during the drying operation is carried to the lint filter device 14 by the circulating air, and most of it is collected by the first filter 23. Next, the fine dust that has passed through the first filter 23 is transferred to the second filter 1.
(Phosphorus collected by 5) - Lint and the like are completely removed from the circulating air that has passed through the filter device 14.

Next, a method for maintaining the lint filter device 14 will be explained.

When the clothes dryer is used several times, a considerable amount of lint is collected in the first filter 23 and the second filter 16, and the opening area becomes smaller than the original size, requiring maintenance to maintain its performance. The first filter 23 can be removed by pulling it from the filter guard 22 by hand. The second filter 16 has a plurality of fixing pieces 18 arranged around the knob portion 20 of the second filter 16.
By rotating the drum 2 by 80 degrees, the fixing claw 15 changes from the position shown by the solid line to the position shown by the dashed line.
The first filter 23. is disengaged and can be removed from the rear of the rotating drum 2. The second filter 16 can be easily removed from the dryer body and its maintenance can be easily performed.

(Effects of the Invention) Since the present invention is configured as described below, maintenance of the lint filter device can be performed on the main parts.

Therefore, each filter can always be kept free from clogging, and the drying time will not be unnecessarily long.
