Dryer and apparatus for removing lint

The present invention relates to a dryer and an apparatus for removing foreign matter from the dryer.

In general, a dryer is a device that blows hot air generated by a heater into a rotary drum to absorb moisture of a drying object (for example, clothing in a state in which washing is completed), thereby performing drying on the drying object.

The dryers are largely classified into exhaust type dryers and condensation dryers according to a treatment method of wet air containing moisture generated by drying the drying object. In detail, the exhaust dryer uses a method of discharging the humid air discharged from the drum to the outside of the dryer, and the condensation dryer dries the moisture from the drum in a heat exchanger to remove moisture and then removes moisture. The air is heated again and sent to the drum for recycling.

On the other hand, since the drum is rotatably formed, the drying object accommodated in the drum is rocked in the drum as the drum rotates. In this process, foreign substances contained in the drying object are spread into the air. That is, foreign matter is contained in the air passing through the drum.

Foreign matter contained in the air may cause a failure while passing through the mechanical components of the dryer, or may be harmful to the user's health if discharged to the outside of the dryer. Therefore, the air passing through the drum must pass through the filter to remove the foreign matter.

Generally, the filter is provided in front of the drum to filter out foreign matter contained in the air passing through the drum. If foreign matter accumulates at a predetermined level or more in the filter, the air flow is disturbed, so cleaning is required. In general, the filter is detachably coupled to the dryer, and after the drying stroke, the user separates and cleans the filter.

In particular, the foreign matter is contained in the wet air, it contains moisture, and thus adheres to the filter. In addition, when the amount of moisture contained in the air decreases as the drying process proceeds, the wet substance is dried and adhered to the filter. Therefore, in order to clean the filter cleanly, there is a problem in that the user needs to clean the filter with strong force.

If the filter is left in a state in which foreign matter is fixed, the air volume is not secured, and thus the air heated by the heater cannot be cooled, which may cause a fire.

Therefore, when the first gear 431 is rotated, the separation unit 400 moves in the vertical direction, and at the same time the separation mechanism 410 is rotated. That is, the brush 412 or the protrusion 415 is reciprocated in the vertical direction while being rotated. In other words, the brush 412 or the protrusion 415 cleans the filter 332 by reciprocating motion and also by rotating motion. That is, since the foreign matter filtered by the filter 332 is removed in duplicate, the filter 332 is more surely cleaned.

In detail, foreign matter is filtered and fixed to the filter 332, and the brush 412 is moved in close contact with the filter 332. Therefore, as the brush 412 moves, the foreign matter that has been filtered out of the filter 332 is separated from the filter 332 and falls downward by gravity.

In this case, the same effect may be obtained even if the protrusion 415 is provided instead of the brush 412.

The foreign matter dropped downward is stored in the foreign material case 390 through the foreign material discharge port 360, and is separated and discharged when the foreign matter is stored at a predetermined level or more in the foreign material case 390.

According to the dryer 10 and the foreign matter removing apparatus 300 according to the embodiment of the present invention as described above, the foreign matter adhered to the filter 332 is automatically removed can give a luxurious image for the product, There is an effect that the user's satisfaction is increased.

In addition, the user does not need to clean the filter 332 every time the dryer 10 is used, and when the foreign matter is stored in the foreign material case 390 or more, the foreign matter case 390 is removed to remove the foreign matter only. Because it is internal, there is an advantage that the ease of use is maximized.

In addition, when the filter 332 is automatically cleaned, there is no risk of fire because the amount of air passing through the drum 200 is maintained at a predetermined level or more.
