Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a clothes dryer used in general households and the like.

Conventional configuration and its problems Conventionally, as a configuration for automatically removing dust attached to a filter during operation of a clothes dryer, for example,
As disclosed in No. 17039, there is a device in which the shaft of the brush body is engaged with a fixed shaft fixed to the exhaust system side so that the brush rotates in contact with the filter, but it is difficult to insert the filter cover. If it was perfect, there would be disadvantages such as insufficient meshing and idling, and a complicated structure such as the provision of a fixed shaft and the provision of meshing parts.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and an object thereof is to provide a clothes dryer that is simple in structure and free from idling.

Structure of the Invention In order to achieve the above-mentioned object, the clothes dryer of the present invention includes a filter cover that is detachably attached to the inside of a protrusion formed by protruding the rear central part of the rotary drum outward with respect to the exhaust part. A brush is provided with a filter removably attached within the filter cover, and a brush that is rotatably fitted onto a boss provided in the center of the filter cover and that contacts the filter with a brush body that is directed downward by gravity. It has a section.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is a clothes input port 2 on the front side and a fan 3 on the back side.
5 is a door for opening and closing the clothes input port 2; 6 is a drum installed in the main body 1 and rotatably supported by bearings 7 and 8; 9;
1 is a motor for driving the rotating drum 6 and the fan 3; 10 is a heater for supplying hot air into the rotating drum 6; 11 is an exhaust device 4 on the rear surface of the rotating drum 6;
A protrusion 12 is formed to protrude outward at a portion opposite to the protrusion 1 and has a large number of holes 11a in its wall.
A synthetic resin filter cover 14 is removably provided inside the filter cover 1 and has a ventilation hole 13 and a finger hole 13a. This is a removably fitted filter.

14a is a filter mesh of this filter 14. Reference numeral 15 denotes a shaft screwed to the center of the protruding portion 11 of the rotating drum 6, and the boss portion 12a of the filter cover 12 is elastically and detachably fitted onto the shaft 15. Reference numeral 16 denotes a brush main body, the ring portion 16a of which is rotatably fitted onto the boss portion 12a of the filter cover 12, and has an inner diameter d2 smaller than the thicker outer diameter portion dl at the tip of the boss portion 12a. It is formed and the extraction is stopped.

Further, the brush portion 17 attached to the brush body 16 hanging from the ring portion 16a is made of a soft material such as a brush or felt, and is in contact with the filter mesh 14a. Furthermore, the brush body 16 serves as a weight.

The operation in the above configuration will be explained. Dust generated from clothes during the operation of the clothes dryer adheres to and accumulates on the surface of the filter mesh 14a. If this dust is left to accumulate, the circulation of the hot air a will be impaired, and the drying effect will be adversely affected, such as by taking a long time to dry or causing the temperature to rise abnormally. Therefore, it is necessary to clean the filter 14 every time after drying the clothes. Therefore, it is convenient to automatically remove accumulated dust from the filter mesh 14a. Therefore, in order to automatically remove this dust, the brush portion 17 is in soft contact with the surface of the filter mesh 14a.

While the drum 6 is rotating in the direction indicated by the arrow in FIG. Since it is freely fitted to the outside and serves as a weight, it is always kept at a stationary position where it rotates relative to the rotation of the drum 6 (it remains facing downward due to gravity), and the brush part 17 is attached to the filter mesh. Continue brushing the surface of the shoe 14a. The brushed dust is pushed to the position shown in Figure 3C and accumulates, so it is only necessary to remove the filter cover 12 and clean the filter 14 periodically (once every 10 drying operations, etc.). .

Effects of the Invention As described above, according to the present invention, cotton lint and dust contained in the exhaust flow are captured by the filter and constantly removed, so there is no prolongation of drying time or abnormal rise in hot water temperature, and the filter There is no need to clean it after each use, and you only need to clean it once every few times, making it easier to use.The filter brush uses a weight to perform relative contact rotation movement on the filter surface Therefore, the structure is extremely simple, and there are effects such as reliable brushing without the worry of idling unlike the conventional brushing.
