Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a clothes dryer having a rotating drum for storing items to be dried.

Structure of a conventional clothes dryer and its problems The structure of a conventional clothes dryer is shown in FIGS. 1 and 2. The dryer body 1 is equipped with a rotating drum 2 that stores the material to be dried, and the drum 2 includes filters 3, 3' for collecting lint;
A filter cover 4 covering 3' is removably provided. Reference numeral 5 denotes a fan casing, and a fan 6 is installed inside the fan casing to constitute 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 is provided with an exhaust port 8. Reference numeral 9 is a drum bearing fixed to the center of the drum 2. 10 is a shaft, and a fixing plate 11 fixed to the dryer main body 1
is fixed to the drum 2 and the fan bearing 1.
A fan 6 into which 2 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 the motor 14 is controlled by a pulley 15;
The fan 6 is rotated via the belt 16 and the pulley 7, and the drum 2 is also driven at the same time. 17 is a dry air intake port, and 18 is a door.

In a conventional clothes dryer, items to be dried (not shown) are stored in a drum 2 and when operation is started, the drum 2 and fan 6 rotate. At the same time heating means 13
is energized, the drying air is heated, accelerates drying of the material to be dried in the drum 2, and is exhausted from the exhaust port 8.

During drying, the material to be dried rolls as the drum 2 rotates, so 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 material to be dried, etc. are applied. Cotton dust (hereinafter referred to as lint) is generated and collected by the filters 3 and 3'.
However, most of the lint will 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 cleaning of the filters 3, 3' is neglected, the filters 3, 3' become clogged, the drying air flow rate 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 is thrown up. It was not good enough in terms of usability and drying performance.

Purpose of the Invention The present invention provides a clothes dryer that has stable drying performance and is easy to use by automatically cleaning lint collected on a filter and collecting the lint in one place. It is.

Composition of the Invention In order to achieve this object, the present invention provides a dust collection means in a rotating drum that stores the material to be dried, and the dust collection means includes a filter for collecting lint,
It consists of a lint storage chamber that is detachably provided to correspond to the filter, and a rotating brush that is installed in the lint storage chamber to remove lint.The filter is installed to rotate in synchronization with the drum, and is independent of the rotational movement of the filter. The lint storage chamber is removably provided on the filter cover provided in the open state, and the rotation of the drum of the rotating brush is driven via an idler pulley.

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

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 in the conventional example are given the same reference numerals and their explanation 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. A filter cover 20 is stationary independent of the rotation of the filter 19, 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 parts 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. Rotating brush 22
is provided with an idler pulley 23 on its shaft 22',
As a result, it is driven by the rotation of the drum 2. 2
4 indicates the rotation direction of the drum 2, and 25 indicates the rotating brush 2.
2 rotation directions are shown, respectively. 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, the filter 19 rotates in synchronization with the drum 2, but since the lint storage chamber 21 is provided on the filter cover 20 which is fixed to the drum bearing 9 and is stationary, the rotating brush 22 scrapes the lint off the filter 19. It can thoroughly clean the entire surface of the filter, keeping the filter surface clean at all times. As a result, it is possible to realize a clothes dryer with stable drying performance in which the drying air volume does not decrease and therefore the drying time does not become long.

Furthermore, the lint storage chamber 2 is
The lint 26 collected in the lint storage chamber 21
By removing the lint from the filter cover 20 and opening the lint storage chamber 21, the lint can be easily thrown away without getting your hands dirty (Fig. 6), making it easy to use.

In addition, as shown in FIG. 7, the lint storage chamber 21
If the brush 27 is provided in contact with the filter 19, the brush 27 will stop the lint, so
Scattering during lint removal by the rotating brush 22 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 the rotating drum that stores the items to be dried, and this dust collection means includes a filter for collecting lint and a It consists of a correspondingly removable lint storage chamber and a rotating brush installed in the lint storage chamber to remove lint.The filter rotates in synchronization with the drum, and the filter cover remains stationary independently of the rotation of the filter. By driving the rotation of the drum through the idler pulley, the rotating brush can reliably keep the filter surface clean at all times, creating a clothes dryer with stable drying performance and making it easy to remove collected lint. We can provide a clothes dryer that is easy to use and can handle
The effect is great.
