Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a clothes dryer in which items to be dried are stored in a rotating drum and dried.

2. Construction of a conventional clothes dryer and its problems 2. The construction of a conventional clothes dryer is shown in FIGS. 1 and 2. In the figure, a main body 1 of the dryer is equipped with a rotating drum 2 for storing materials to be dried, and inside the rotating drum are filters 3 and 3' that collect lint generated from the materials to be dried. A filter cover 4 is provided so as to be detachable. 5 is the fan casing,
A fan 6 for guiding dry air into the rotating drum 2 is installed inside, and a pulley 7 is integrated with the fan 6. Further, the fan casing 5 communicates with the rotating drum 2 and is provided with an exhaust port 8. A drum bearing 9 is fixed to the center of the rotating drum 2.

Reference numeral 10 denotes a shaft supporting the rotating drum 2, which is fixed to a fixed plate 11 fixed to the main body 1, and rotatably supports the rotating drum 2 and the fan 6 into which fan bearings 12 and 12' are press-fitted. There is.

13 is a heater that heats the dry air, 14 is a motor, and the rotation of the motor 14 is controlled by a pulley 15. belt 16, pulley 7
is transmitted to the fan 6 via.

It is also transmitted to the rotating drum 2 at the same time. 17 is a dry air intake port, and 18 is a door.

The operation of a conventional clothes dryer will be described below. When the material to be dried (not shown) is stored in the rotating drum 2 and the operation is started, the rotating drum 2. Fan 6 rotates. At the same time, heater 1
3 is energized, the drying air is heated, accelerates drying of the material to be dried on the rotating drum 2, and is exhausted from the exhaust port 8.

During drying, the material to be dried rolls with the rotation of the drum 2, which causes various mechanical forces such as friction between the materials to be dried, friction between the materials to be dried and the rotating drum 2, twisting and pulling of the material to be dried, etc. , and fabric dust (hereinafter referred to as lint) is generated. The generated lint is collected by filters 3, 3'. However, most of the lint will be collected by the filter 3.

2. The problem is that before using the dryer, it is necessary to clean the filters 3 and 3' every time. Due to clogging, the amount of drying air decreases, leading to a decrease in the input to the heater 13, and the drying time becoming longer.
There are drawbacks in terms of ease of use and drying performance, such as the fact that it is difficult to clean the filter 3, a layer of lint adheres to the surface of the filter 3, which is difficult to remove, and fine dust is thrown up.

OBJECTS OF THE INVENTION The present invention overcomes the drawbacks of conventional lint filters as described above. That is, it is an object of the present invention to provide a clothes dryer in which the filter is less likely to be clogged without cleaning for a long period of time, and the generated lint is collected in a predetermined portion in the form of a lump to facilitate cleaning.

Structure of the Invention The clothes dryer of the present invention is provided with a comb-shaped lint collector on the surface of a filter for collecting lint generated from drying materials, and removes the lint accumulated in a layer on the filter surface by the rotation of the filter itself. The lint collector is configured to collect dust in lumps using the lint collector.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 6-74. The basic configuration of the clothes dryer is the same as that shown in FIGS. 1 and 2. A shaft 20 fixed to the fixed plate 11 in FIGS.
3.23' is locked for synchronous rotation with the rotating drum 21. In addition, a comb-shaped lint collector 26 is provided in the gap formed between the filter 23 and the filter cover 24 for secondary collection of lint by contacting the surface of the filter 23.
This lint collector 25 has one end connected to the tip 2 of the shaft 2o.
0' and is removably locked, the back surface is held down by a protrusion 24' at the center of the filter cover 24, and the other end is a free end. That is, the lint collector 25 is held in a cantilevered position in close contact with the flat portion of the outer ring 26 of the filter 23. The picking part 27 of the lint collector 26 is located so as to cross from the center to the outer circumference of the filter 23, and is held stationary regardless of the rotation of the filter 23.

Next, this effect will be explained. 216 rotary drums
When the material to be dried is stored in the rotary drum and the drying operation is started, the humidity inside the rotating drum begins to decrease, and lint begins to form from the material to be dried. The lint floats along with the flow of dry air indicated by the dotted line in FIG. The filter 23, which rotates in synchronization with the rotating drum 21, collects the particles in a layer over the entire surface of the inside of the drum chamber, and the collected particles rotate together with the filter 23.

Conventionally, this operation continued, and the collected lint accumulated over the entire surface of the filter 230, reducing the flow rate of drying air and deteriorating the drying performance. However, the picking part 27 of the lint collector 25 of the embodiment has the effect of entangling the lint collected on the surface of the rotating filter 23, and before the lint is deposited on the surface of the filter 23, it is The lint is locally collected to prevent the filter 23 from clogging for a long time. FIG. 4 illustrates this state, and the filter 23
The filter cover 24 is rotated in the direction of the arrow, that is, clockwise, and the lint collected in a layer on the surface of the filter 23 (on the front side of the page) is further transferred to the grip 27 of the lint collector 25 fixed to the shirt 20. The 7 entangled lint particles are thus collected and form a lint mass 28. Even if this lint accumulates, it will be returned to the filter 23; In this way, the lint collected by the filter 23 is locally collected by the lint collector 25.The collected lint h- Filter 23.23'
, filter cover 24. By removing the lint collector 25 from the rotating drum side, it can be easily removed.

Effects of the Invention As is clear from the above embodiments, the clothes dryer of the present invention has the following excellent effects by providing a comb-shaped lint collector.

1. Since lint is locally concentrated and collected, it prevents clogging caused by layered lint accumulation on the filter over a long period of time, and prevents deterioration of drying performance.

2. Therefore, the frequency of cleaning the filter is greatly reduced compared to the conventional method, and it is easy to use.

3. Since the lint is locally collected in clumps, there is less scattering of fine dust from the entire surface of the filter when cleaning it, making it easier to clean.
