Description

Automatic filter device of exhaust type dryer {FLUFFS FILTERING APPARATUS FOR A DRYER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust type clothes dryer, and more particularly, to an automatic filter device for an exhaust type dryer that allows to remove water such as lint generated during the drying process by spraying water.

In general, a clothes dryer includes an exhaust type for drying clothes by introducing outside air, and a dehumidification method for drying clothes while removing moisture while circulating internal air and condensing the removed moisture in a droplet state.

1 is a cross-sectional configuration view showing a conventional exhaust type clothes dryer.

Exhaust-type clothes dryer of the prior art is provided with a drum (20) rotatably installed in the case 10 so that clothes can be dried therein, a drive device (30) for rotating the drum (20), and the drum A heater 25 installed in the suction casing 22 which is the rear of the 20 and heating the suction air, and a fan 35 which is provided in the exhaust duct 27 which is the front lower side of the drum 20 to forcibly flow the air. It is composed of

An opening 11 is formed in the front surface of the case 10 so that clothes can be inserted or removed, and the opening 11 is provided with a door 15 for sealing or opening the drum 20.

The driving device 30 includes a biaxial motor 31 capable of simultaneously rotating the fan 35 and the drum 20, and a pulley 32 and a drum 20 of the biaxial motor 31. It is composed of a belt 33 connected to the circumference to transmit the rotational power.

The drum 20 has a suction port 20a through which the heated outside air is introduced while passing through the heater 25 at the rear thereof, and the exhaust duct 27 receives air drying clothes in the drum 20. A discharge port 27a and an exhaust passage 27b are formed to exhaust the gas.

In particular, on the exhaust passage 27b of the exhaust duct 27, a filter 40 for filtering foreign matter such as lint generated during the drying process of the clothes is installed.

In the conventional clothes dryer configured as described above, as the biaxial motor 31 rotates, the fan 35 rotates at the same time as the drum 20 connected to the belt 33 rotates.

As the fan 35 rotates, outside air is introduced into the suction casing 22, and the outside air is heated while passing through the heater 25 and introduced into the drum 20. As such, the heated air introduced into the drum 20, that is, the hot air, dries the clothes while exchanging heat with the damp clothes, and the hot air, which dries the clothes, discharges 27a and the discharge passage 27b of the exhaust duct 27. Is discharged to the outside through.

In particular, when the hot air passes through the filter 40 when passing through the discharge passage 27b of the exhaust duct 27, foreign substances such as seams are removed while being caught by the filter 40.

However, in the above-described exhaust type clothes dryer of the prior art, since the filter 40 is formed by a filtration method, when a large amount of foreign matter such as seams is attached, the filter 40 is blocked and the blowing resistance is increased, and thus the blowing amount is increased. Since this lowers the drying efficiency, there is a troublesome problem of replacing or cleaning the filter 40 at an appropriate time.

In addition, the user may not easily check with the naked eye, and may miss a time when the filter 40 may be replaced or cleaned. If the filter 40 is not replaced at an appropriate time, the blowing force may be lowered, and the drying efficiency may be reduced. It takes a lot of time to dry and a problem that consumes a lot of power.

The present invention has been made in order to solve the above problems, it is configured to remove the foreign matter such as lint by spraying water to the exhaust air to avoid the need to replace the filter to improve the user convenience and discharge It is an object of the present invention to provide an automatic filter device of an exhaust dryer that prevents passages from being blocked so that drying performance is improved.

The automatic filter device of the exhaust type dryer of the present invention for realizing the above object is an exhaust duct for allowing the air drying the clothes in the drum to be discharged out of the case; A shower separation means installed at one side of the exhaust duct to remove foreign substances such as lint and the like contained in the exhaust air passing through the exhaust duct by spraying water; It is possible to be characterized in that it is provided on the lower side of the exhaust duct includes a drain means for discharging the water and foreign matter injected from the shower separation means.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

2 is an internal configuration diagram showing an exhaust type dryer equipped with an automatic filter device according to the present invention.

Exhaust dryer equipped with an automatic filter device according to the present invention is a drum (60) made to be rotatably installed in the case 50 so that the clothes can be dried therein, and a motor capable of rotating the drum (60) 71 and the belt 73, a heater 65 installed in the suction casing 62, which is rear of the drum 60, to heat intake air, and an exhaust duct 67, which is a front lower side of the drum 60; ) And a fan 75 for forcibly discharging air in the drum 60 by the motor 71.

The case 50 is provided with a door 55 that can be opened and closed to insert or remove clothing into the drum (60).

The exhaust duct 67 is connected to the rear of the case 50 from the lower side of the door 55 so that the air drying the clothes in the drum 60 is discharged.

In particular, the exhaust duct 67 is configured to include a foreign matter separation pipe 80 is formed in the end portion in the vertical direction from the outside of the case 50 to the exhaust port 81 is discharged from the upper side.

An injection nozzle 85 is installed at an upper end of the foreign substance separating tube 80 to remove foreign substances such as lint and the like contained in the discharged air passing through the foreign substance separating tube 80 by spraying water. 85 is connected to the water supply hose 86 to receive water, and a water supply valve (not shown) is installed on the inlet portion of the injection nozzle 85 or the water supply hose 86.

A drain hose 90 is connected to the lower end of the foreign matter separating tube 80 so that the water sprayed from the spray nozzle 85 and the foreign matter removed by the water are discharged.

In addition, a water inflow prevention plate 95 is installed below the foreign substance separation pipe 80 to prevent the water injected from the injection nozzle 85 from flowing into the exhaust duct 67.

Referring to the operation of the automatic filter device of the exhaust type dryer according to the present invention configured as described above are as follows.

The humid air drying the clothes in the drum 60 is discharged to the outside of the case 50 through the exhaust duct 67 according to the operation of the fan 75.

Here, the foreign matter separating tube 80 is installed at the end of the exhaust duct 67, the air discharged through the exhaust duct 67 rises vertically while passing through the foreign matter separating tube 80, and then the exhaust port ( Through 81).

At this time, when water is injected from the injection nozzle 85 installed at the upper end of the foreign matter separation pipe 80, foreign matters such as lint and the like contained in the discharged air are separated by the water and dropped to the lower side, and then the outside is discharged through the drain hose 90. By being discharged to the outside it is possible to remove the foreign substances generated in the drying process and discharged with the discharged air.

The automatic filter device of the exhaust type dryer of the present invention configured and operated as described above is configured to remove foreign substances such as lint by spraying water on the discharged air, so that the filter does not need to be replaced. It is possible to improve and also to provide an advantage that the discharge passage is not clogged to improve the drying performance.
