Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a clothes dryer having a rotating drum for storing items to be dried.

Conventional Structure and Problems The structure of a conventional clothes dryer is shown in FIGS. 1 and 2. The dryer main body 1 is equipped with a rotating drum 2 that stores the material to be dried, and inside the drum 2 are filters 3 and 3' for collecting lint, and a filter that covers the filters 3 and 3'. A cover 4 is provided in a detachable manner. Reference numeral 5 denotes a fan casing, which is equipped with a fan 6 inside and constitutes an air blowing means. 7 is a pulley, which is integrated with the fan 6. Further, the fan casing 5 communicates with the drum 2, and 09, which is provided with an exhaust port 8, is a drum bearing.
is fixed at the center. A shaft 1o is fixed to a fixed plate 11 fixed to the dryer main body 1, and is attached to the drum 2.
A fan 6, into which fan bearings 12 and 12' are press-fitted, is rotatably supported.

13 is a heating means consisting of a semiconductor heater having positive temperature characteristics for heating dry air; 14 is a motor;
The rotation of 4 rotates the fan 6 via the pulley 15, belt 16, and pulley 7, and also drives the rotary drum 2 at the same time.

17 is a dry air intake port, and 18 is a door.

In a conventional clothes dryer, when drying items (not shown) are stored in the drum 2 and the operation is started, the drum 2 and the fan 6
rotates. At the same time, the heating means 13 is energized, the drying air is heated, accelerates the drying of the material to be dried in the drum 2, and is exhausted from the air opening 8. As the drying materials roll, various mechanical forces such as friction between the materials to be dried, friction between the materials to be dried and the drum 2, twisting and pulling of the materials to be dried, etc. are applied, and fluff (hereinafter referred to as lint) is generated, which can damage the filter. 3,3
′ is collected. However, most of the lint is likely to be collected by the filter 3.

However, there are problems (1): It is necessary to clean the filters 3, 3' each time before using the dryer.

(2) If the filters 3, 3' are not cleaned, the filters 3, 3' become clogged, the flow rate of drying air decreases, the input to the semiconductor heater 13 decreases, and the drying time becomes longer. (3) When cleaning the filter 3, a layer of lint adheres to the surface of the filter 3, which is difficult to remove, and when it is removed, fine dust will fly around. etc. are opened,
It was not good enough in terms of ease of use and drying performance.

Purpose of the Invention The present invention automatically cleans the lint collected on the filter and collects the lint in one place.
To provide a clothes dryer that has stable drying performance and is easy to use.

Structure of the Invention In order to achieve this object, the present invention provides a dust collecting means in a rotating drum that houses the material to be dried, and the dust collecting means includes a filter for collecting lint, and a filter for collecting lint. - A removable lint storage room that accommodates filters,
The lint storage chamber is equipped with a rotating brush that removes lint.

With this configuration, the particles collected on the filter are removed by a rotating brush, and by keeping the filter surface clean at all times, the volume of drying air can be kept constant and stable drying performance can be achieved. . In addition, by collecting the removed lint in the lint storage chamber, there is no need to clean the filter after each operation, and the collected lint can be easily cleaned by removing the lint storage chamber. It is.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Components that are the same as those of the conventional example will be given the same reference numerals and their explanations will be omitted.

3 to 7 mainly show the dust collecting means in one embodiment of the present invention, and 19 is a filter fixed to the drum 2, which rotates in synchronization with the drum 2. 2o is a filter cover that stands still and is detachably fixed to the drum bearing 9. A lint storage chamber 21 is detachably provided in the filter cover 20, and the lint storage chamber 21 has a structure that can be divided into two using a hinge 21 or the like. A rotating brush 22 that rotates in contact with the surface of the filter 19 is provided in the lint storage chamber 21. The rotating brush 22 has an idler pulley 23 on its shaft 22, and is driven by the rotation of the drum 2. 24 indicates the rotation direction of the drum 2, and 25 indicates the rotation direction of the rotating brush 22. Further, 26 is the collected lint.

The operation of the clothes dryer configured as above will be explained below. When the operation starts, the drum 2 rotates, the idler pulley 23 in contact with the drum 2 rotates, and the rotating brush 22 also rotates. At this time filter 19
The filter cover 2 rotates in synchronization with the drum 2, but the lint storage chamber 21 is fixed to the drum bearing 9 and remains stationary.
0, the rotating brush 22 removes the lint from the brush 7.

The entire surface of the filter 19 can be thoroughly cleaned, and the filter surface is always kept clean.

As a result, it is possible to realize a clothes dryer with stable drying performance in which the drying air flow rate does not decrease and the drying time does not increase accordingly.

Furthermore, the lint 26 collected on the rotating brush 22 and in the L lint storage chamber 21 can be easily disposed of without getting your hands dirty by removing the lint storage chamber 21 from the filter cover 20 and opening the lint storage chamber 21. Done (Figure 6)
, it is easy to use.

In addition, if a brush 27 is provided in the 91: sea urchin, suction storage chamber 21 itself shown in FIG. Scattering can be reduced and lint can be collected more efficiently.

Effects of the Invention As described above, the clothes dryer of the present invention is provided with a dust collection means in a rotating drum that stores the items to be dried, and this dust collection means has a filter for collecting lint and a filter. This clothes dryer has a removable lint storage chamber and a rotating brush installed inside the lint storage chamber to remove lint, allowing the filter surface to be kept clean at all times and providing stable drying performance. In addition, it is possible to provide an easy-to-use clothes dryer that can easily process collected lint, and its effects are significant.
